bi-directionality. The only evidence that has survived are inscriptions found on various artifacts. The Nautae Parisiaci monument was probably constructed by Gaulish sailors in 14 CE. It was discovered in 1710 within the foundations of the cathedral of Notre-Dame de Paris, site of ancient Lutetia, the civitas capital of the Celtic Parisii. It is now displayed in the Musée National du Moyen Age in Paris. The distinctive stone pillar is an important monument of Gallo-Roman religion. Its low reliefs depict and label by name several Roman deities such as Jupiter, Vulcan, and Castor and Pollux, along with Gallic deities such as Esus, Smertrios, and Tarvos Trigaranus. The name Cernunnos can be read clearly on 18th century drawings of the inscriptions, but the initial letter has been obscured since, so that today only a reading "[_]ernunnos" can be verified. Additional evidence is given by one inscription on a metal plaque from Steinsel-Rëlent in Luxembourg, in the territory of the Celtic Treveri. This inscription read Deo Ceruninco, "to the God Cerunincos", assumed to be the same deity. The Gaulish inscription from Montagnac reads αλλετ[ει]νος καρνονου αλ[ι]σο[ντ]εας (Alletinos [dedicated this] to Carnonos of Alisontea), with the last word possibly a place name based on Alisia, "service-tree" or "rock" (compare Alesia, Gaulish Alisiia). Iconography On the Pillar of the Boatmen, we find an image depicted with stag's antlers, both having torcs hanging from them with the inscription of [C]ernunnos with it. The lower part of the relief is lost, but the dimensions suggest that the god was sitting cross-legged, in the depiction traditionally called "Buddhic posture", providing a direct parallel to the antlered figure on the Gundestrup cauldron. Iconography associated with Cernunnos is often portrayed with a stag and the ram-horned serpent. Less frequently, there are bulls (at Rheims), dogs and rats. Because of the image of him on the Gundestrup Cauldron, some scholars describe Cernunnos as the Lord of the Animals or the Lord of Wild Things, and Miranda Green describes him as a "peaceful god of nature and fruitfulness" who seems to be seated in a manner that suggests traditional shamans who were often depicted surrounded by animals. Other academics such as Ceisiwr Serith describes Cernunnos as a god of bi-directionality and mediator between opposites, seeing the animal symbolism in the artwork reflecting this idea. The Pilier des nautes links him with sailors and with commerce, suggesting that he was also associated with material wealth as does the coin pouch from the Cernunnos of Rheims (Marne, Champagne, France)—in antiquity, Durocortorum, the civitas capital of the Remi tribe—and the stag vomiting coins from Niedercorn-Turbelslach (Luxembourg) in the lands of the Treveri. The god may have symbolized the fecundity of the stag-inhabited forest. Other examples of Cernunnos imagery include a petroglyph in Val Camonica in Cisalpine Gaul. The antlered human figure has been dated as early as the 7th century BCE or as late as the 4th. Two goddesses with antlers appear at Besançon and Clermont-Ferrand, France. An antlered god appears on a relief in Cirencester, Britain dated to Roman times and appears depicted on a coin from Petersfield, Hampshire. An antlered child appears on a relief from Vendeuvres, flanked by serpents and holding a purse and a torc. The best known image appears on the Gundestrup cauldron found on Jutland, dating to the 1st century BCE, thought to depict Celtic subject matter though usually regarded as of | Cycle. In this line of interpretation, Cernach is taken as an epithet with a wide semantic field—"angular; victorious; prominent," though there is little evidence that the figures of Conall and Cernunnos are related. A brief passage involving Conall in an eighth-century story entitled Táin Bó Fraích ("The Cattle Raid on Fraech") has been taken as evidence that Conall bore attributes of a "master of beasts." In this passage Conall Cernach is portrayed as a hero and mighty warrior who assists the protagonist Fraech in rescuing his wife and son, and reclaiming his cattle. The fort that Conall must penetrate is guarded by a mighty serpent. The supposed anti-climax of this tale is when the fearsome serpent, instead of attacking Conall, darts to Conall's waist and girdles him as a belt. Rather than killing the serpent, Conall allows it to live, and then proceeds to attack and rob the fort of its great treasures the serpent previously protected. The figure of Conall Cernach is not associated with animals or forestry elsewhere; and the epithet "Cernach" has historically been explained as a description of Conall's impenetrable "horn-like" skin which protected him from injury. Possible connection to Saint Ciarán Some see the qualities of Cernunnos subsumed into the life of Saint Ciarán of Saighir, one of the Twelve Apostles of Ireland. When he was building his first tiny cell, as his hagiography goes, his first disciple and monk was a boar that had been rendered gentle by God. This was followed by a fox, a badger, a wolf and a stag. Neopaganism and Wicca Within Neopaganism, specifically the Wiccan tradition, The Horned God is a deity that is believed to be the consort of the Great Goddess and syncretizes various horned or antlered gods from various cultures. The name Cernunnos became associated with the Wiccan Horned God through the adoption of the writings of Margaret Murray, an Egyptologist and folklorist of the early 20th century. Murray, through her Witch-cult hypothesis, believed that the various horned deities found in Europe were expressions of a "proto-horned god" and in 1931 published her theory in "The God of the Witches". Her work was considered highly controversial at the time, but was adopted by Gerald Gardner in his development of the religious movement of Wicca. Within the Wiccan tradition, The Horned God reflects the seasons of the year in an annual cycle of life, death and rebirth and his imagery is a blend of the Gaulish god Cernunnos, the Greek god Pan, The Green Man motif, and various other horned spirit imagery.

In languages without , such as Zulu, may be written gq. was proposed by Clement Doke, and by Beach, but did not catch on. The former is not supported by Unicode, and the latter was proposed only in 2020. (Doke's character resembles a down arrow and is here represented by the old Roman numeral for 50; Beach is a double-barred esh.) Three of these, , and , were adopted into the IPA, though eventually abandoned. Doke and Beach used additional or modified letters for voiced and nasal clicks, but they did not catch on. The labial and palatal clicks do not occur in written Bantu languages. However, the palatal clicks have been romanised in Naron, Juǀʼhõasi and !Xun, where they have been written , and , respectively. In the 19th century, they were sometimes written , which might be source of the Doke letter . There are a few less-well-attested articulations. A reported subapical retroflex articulation in Grootfontein !Kung turns out to be alveolar with lateral release, ; Ekoka !Kung has a fricated alveolar click with an s-like release, provisionally transcribed ; and Sandawe has a "slapped" alveolar click, provisionally transcribed (in turn, the lateral clicks in Sandawe are more abrupt and less noisy than in southern Africa). However, the Khoisan languages are poorly attested, and it is quite possible that, as they become better described, more click articulations will be found. Formerly when a click consonant was transcribed, two symbols were used, one for each articulation, and connected with a tie bar. This is because a click such as was analysed as a nasal velar rear articulation pronounced simultaneously with the forward ingressive release . The symbols may be written in either order, depending on the analysis: or . However, a tie bar was not often used in practice, and when the manner is tenuis (a simple ), it was often omitted as well. That is, = = = = . Regardless, elements that do not overlap with the forward release are usually written according to their temporal order: Prenasalisation is always written first ( = = ), and the non-lingual part of a contour is always written second ( = = ). However, it is common to analyse clicks as simplex segments, despite the fact that the front and rear articulations are independent, and to use diacritics to indicate the rear articulation and the accompaniment. At first this tended to be for , based on the belief that the rear articulation was velar; but as it has become clear that the rear articulation is often uvular or even pharyngeal even when there is no velar–uvular contrast, voicing and nasalisation diacritics more in keeping with the IPA have started to appear: for . In practical orthography, the voicing or nasalisation is sometimes given the anterior place of articulation: dc for and mʘ for , for example. In the literature on Damin, the clicks are transcribed as . Places of articulation Places of articulation are often called click types, releases, or influxes, though 'release' is also used for the accompaniment/efflux. There are seven or eight known places of articulation, not counting slapped or egressive clicks. These are (bi)labial affricated , or "bilabial"; laminal denti-alveolar affricated , or "dental"; apical (post)alveolar plosive , or "alveolar"; laminal palatal plosive , or "palatal"; laminal palatal affricated (known only from Ekoka !Kung); subapical postalveolar , or "retroflex" (only known from Central !Kung and possibly Damin); and apical (post)alveolar lateral , or "lateral". Languages illustrating each of these articulations are listed below. Given the poor state of documentation of Khoisan languages, it is quite possible that additional places of articulation will turn up. No language is known to contrast more than five. Extra-linguistically, Coatlán Zapotec of Mexico uses a linguolabial click, , as mimesis for a pig drinking water, and several languages, such as Wolof, use a velar click , long judged to be physically impossible, for backchanneling and to express approval. An extended dental click with lip pursing or compression ("sucking-teeth"), variable in sound and sometimes described as intermediate between and , is found across West Africa, the Caribbean and into the United States. The exact place of the alveolar clicks varies between languages. The lateral, for example, is alveolar in Khoekhoe but postalveolar or even palatal in Sandawe; the central is alveolar in Nǀuu but postalveolar in Juǀʼhoan. Names found in the literature The terms for the click types were originally developed by Bleek in 1862. Since then there has been some conflicting variation. However, apart from "cerebral" (retroflex), which was found to be an inaccurate label when true retroflex clicks were discovered, Bleek's terms are still considered normative today. Here are the terms used in some of the main references. {|class="wikitable" |+ Names in the literature ! Click type !! Bleek (1862) !!

However, the palatal and alveolar clicks frequently had conflicting names in older literature, and still do in Unicode. However, since Ladefoged & Traill (1984) clarified the places of articulation, the terms listed under Vosser (2013) have become standard, apart from details such as whether and are alveolar and postalveolar, or is bilabial or labiodental, in a particular language, or whether the rear articulation is velar, uvular or pharyngeal, which again varies between languages (or may even be contrastive within a language). The back-vowel constraint In several languages, including Nama and Juǀʼhoan, the alveolar click types and only occur, or preferentially occur, before back vowels, whereas the dental and palatal clicks occur before any vowel. The effect is most noticeable with the high front vowel . In Nama, for example, the diphthong is common but is rare after alveolar clicks, whereas the opposite is true after dental and palatal clicks. This is a common effect of uvular or uvularised consonants on vowels in both click and non-click languages. In Taa, for example, the back-vowel constraint is triggered by both alveolar clicks and uvular stops, but not by palatal clicks or velar stops: sequences such as and are rare to non-existent, whereas sequences such as and are common. It is also triggered by labial clicks, though not by labial stops. Clicks subject to this constraint involve a sharp retraction of the tongue during release. Miller and colleagues (2003) used ultrasound imaging to show that the rear articulation of the alveolar clicks () in Nama is substantially different from that of palatal and dental clicks. Specifically, the shape of the body of the tongue in palatal clicks is very similar to that of the vowel , and involves the same tongue muscles, so that sequences such as involved a simple and quick transition. The rear articulation of the alveolar clicks, however, is several centimetres further back, and involves a different set of muscles in the uvular region. The part of the tongue required to approach the palate for the vowel is deeply retracted in , as it lies at the bottom of the air pocket used to create the vacuum required for click airstream. This makes the transition required for much more complex and the timing more difficult than the shallower and more forward tongue position of the palatal clicks. Consequently, takes 50 ms longer to pronounce than , the same amount of time required to pronounce . Languages do not all behave alike. In Nǀuu, the simple clicks trigger the and allophones of and , whereas do not. All of the affricated contour clicks, such as , do as well, as do the uvular stops . However, the occlusive contour clicks pattern like the simple clicks, and does not trigger the back-vowel constraint. This is because they involve tongue-root raising rather than tongue-root retraction in the uvular-pharyngeal region. However, in Gǀwi, which is otherwise largely similar, both and trigger the back-vowel constraint (Miller 2009). Manners of articulation Click manners are often called click accompaniments or effluxes, but both terms have met with objections on theoretical grounds. There is a great variety of click manners, both simplex and complex, the latter variously analysed as consonant clusters or contours. With so few click languages, and so little study of them, it is also unclear to what extent clicks in different languages are equivalent. For example, the of Khoekhoe, of Sandawe and of Hadza may be essentially the same phone; no language distinguishes them, and the differences in transcription may have more to do with the approach of the linguist than with actual differences in the sounds. Such suspected allophones/allographs are listed on a common row in the table below. Some Khoisan languages are typologically unusual in allowing mixed voicing in non-click consonant clusters/contours, such as , so it is not surprising that they would allow mixed voicing in clicks as well. This may be an effect of epiglottalised voiced consonants, because voicing is incompatible with epiglottalisation. Phonation As do other consonants, clicks vary in phonation. Oral clicks are attested with four phonations: tenuis, aspirated, voiced and breathy voiced (murmured). Nasal clicks may also vary, with plain voiced, breathy voiced / murmured nasal, aspirated and unaspirated voiceless clicks attested (the last only in Taa). The aspirated nasal clicks are often said to have 'delayed aspiration'; there is nasal airflow throughout the click, which may become voiced between vowels, though the aspiration itself is voiceless. A few languages also have pre-glottalised nasal clicks, which have very brief prenasalisation but have not been phonetically analysed to the extent that other types of clicks have. All languages have nasal clicks, and all but Dahalo and Damin also have oral clicks. All languages but Damin have at least one phonation contrast as well. Complex clicks Clicks may be pronounced with a third place of articulation, glottal. A glottal stop is made during the hold of the click; the (necessarily voiceless) click is released, and then the glottal hold is released into the vowel. Glottalised clicks are very common, and they are generally nasalised as well. The nasalisation cannot be heard during the click release, as there is no pulmonic airflow, and generally not at all when the click occurs at the beginning of an utterance, but it has the effect of nasalising preceding vowels, to the extent that the glottalised clicks of Sandawe and Hadza are often described as prenasalised when in medial position. Two languages, Gǀwi and Yeyi, contrast plain and nasal glottalised clicks, but in languages without such a contrast, the glottalised click is nasal. Miller (2011) analyses the glottalisation as phonation, and so considers these to be simple clicks. Various languages also have prenasalised clicks, which may be analysed as consonant sequences. Sotho, for example, allows a syllabic nasal before its three clicks, as in nnqane 'the other side' (prenasalised nasal) and seqhenqha 'hunk'. There is ongoing discussion as to how the distinction between what were historically described as 'velar' and 'uvular' clicks is best described. The 'uvular' clicks are only found in some languages, and have an extended pronunciation that suggests that they are more complex than the simple ('velar') clicks, which are found in all. Nakagawa (1996) describes the extended clicks in Gǀwi as consonant clusters, sequences equivalent to English st or pl, whereas Miller (2011) analyses similar sounds in several languages as click–non-click contours, where a click transitions into a pulmonic or ejective articulation within a single segment, analogous to how English ch and j transition from occlusive to fricative but still behave as unitary sounds. With ejective clicks, for example, Miller finds that although the ejective release follows the click release, it is the rear closure of the click that is ejective, not an independently articulated consonant. That is, in a simple click, the release of the rear articulation is not audible, whereas in a contour click, the rear (uvular) articulation is audibly released after the front (click) articulation, resulting in a double release. These contour clicks may be linguo-pulmonic, that is, they may transition from a click (lingual) articulation to a normal pulmonic consonant like (e.g. ); or linguo-glottalic and transition from lingual to an ejective consonant like (e.g. ): that is, a sequence of ingressive (lingual) release + egressive (pulmonic or glottalic) release. In some cases there is a shift in place of articulation as well, and instead of a uvular release, the uvular click transitions to a velar or epigottal release (depending on the description, or ). Although homorganic does not contrast with heterorganic | 115 click phonemes, depending on analysis (clusters vs. contours), and over 70% of words in the dictionary of this language begin with a click. Clicks appear more stop-like (sharp/abrupt) or affricate-like (noisy) depending on their place of articulation: In southern Africa, clicks involving an apical alveolar or laminal postalveolar closure are acoustically abrupt and sharp, like stops, whereas labial, dental and lateral clicks typically have longer and acoustically noisier click types that are superficially more like affricates. In East Africa, however, the alveolar clicks tend to be flapped, whereas the lateral clicks tend to be more sharp. Transcription The five click places of articulation with dedicated symbols in the International Phonetic Alphabet (IPA) are labial , dental , palatal ("palato-alveolar") , (post)alveolar ("retroflex") and lateral . In most languages, the alveolar and palatal types are abrupt; that is, they are sharp popping sounds with little frication (turbulent airflow). The labial, dental and lateral types, on the other hand, are typically noisy: they are longer, lip- or tooth-sucking sounds with turbulent airflow, and are sometimes called affricates. (This applies to the forward articulation; both may also have either an affricate or non-affricate rear articulation as well.) The apical places, and , are sometimes called "grave", because their pitch is dominated by low frequencies; whereas the laminal places, and , are sometimes called "acute", because they are dominated by high frequencies. (At least in the Nǁng language and Juǀʼhoan, this is associated with a difference in the placement of the rear articulation: "grave" clicks are uvular, whereas "acute" clicks are pharyngeal.) Thus the alveolar click sounds something like a cork pulled from a bottle (a low-pitch pop), at least in Xhosa; whereas the dental click is like English tsk! tsk!, a high-pitched sucking on the incisors. The lateral clicks are pronounced by sucking on the molars of one or both sides. The labial click is different from what many people associate with a kiss: the lips are pressed more-or-less flat together, as they are for a or an , not rounded as they are for a . The most populous languages with clicks, Zulu and Xhosa, use the letters c, q, x, by themselves and in digraphs, to write click consonants. Most Khoisan languages, on the other hand (with the notable exceptions of Naro and Sandawe), use a more iconic system based on the pipe . (The exclamation point for the "retroflex" click was originally a pipe with a subscript dot, along the lines of ṭ, ḍ, ṇ used to transcribe the retroflex consonants of India.) There are also two main conventions for the second letter of the digraph as well: voicing may be written with g and uvular affrication with x, or voicing with d and affrication with g (a convention of Afrikaans). In two orthographies of Juǀʼhoan, for example, voiced is written g! or dq, and !x or qg.

Wilbur came to this work reluctantly, but he is driven by having seen the horrors of back-alley operations. Homer, upon learning Wilbur's secret, considers it morally wrong. As a young man, Homer befriends a young couple, Candy Kendall and Wally Worthington, who come to St. Cloud's for an abortion. Homer leaves the orphanage, and returns with them to Ocean View Orchards (Wally's family's orchard) in Heart's Rock, near the Maine coast. Wally and Homer become best friends and Homer develops a secret love for Candy. Wally goes off to serve in the Second World War and his plane is shot down over Burma. He is presumed missing by the military, but Homer and Candy both believe he is dead and move on with their lives, which includes beginning a romantic relationship. When Candy becomes pregnant, they go back to St. Cloud's Orphanage, where their son is born and named Angel. Subsequently, Wally is found in Burma and returns home, paralyzed from the waist down. He is still able to have sexual intercourse but is sterile due to an infection caught in Burma. They lie to the family about Angel's parentage, claiming that Homer decided to adopt him. Wally and Candy marry shortly afterward, but Candy and Homer maintain a secret affair that lasts some 15 years. Many years later, teenaged Angel falls in love with Rose. Rose, the daughter of the head migrant worker at the apple orchard, becomes pregnant by her father, and Homer performs an abortion on her.

The right to represent : Thus, the Act has enabled us as consumers to have the right to represent in the consumer courts. Economics and marketing In an economy, a consumer buys goods or services primarily for consumption and not for resale or for commercial purposes. Consumers pay some amount of money (or equivalent) for something - goods or services - which they (or their families) then consume (use up). As such, consumers play a vital role in the economic system of a capitalist system and form a fundamental part of any economy. Without consumer | consumers play a vital role in the economic system of a capitalist system and form a fundamental part of any economy. Without consumer demand, producers would lack one of the key motivations to produce: to sell to consumers. The consumer also forms one end of the chain of distribution. Recently in marketing, instead of marketers generating broad demographic profiles and Fisio-graphic profiles of market segments, marketers have started to engage in personalized marketing, permission marketing, and mass customization to target potential consumers. Largely due to the rise of the Internet, consumers are shifting more and more towards becoming prosumers, consumers who are also producers (often of information and media on the social web) - they influence the products created (e.g. by customization, crowdfunding or publishing their preferences), actively participate in the production process, or use interactive products. Law and politics The law primarily uses a notion of the consumer in relation to consumer protection laws, and the definition of consumer is often restricted to living persons (not corporations or businesses) and excludes commercial users. A typical legal rationale for protecting the consumer is based on the notion of policing market failures and inefficiencies, such as inequalities of bargaining power between a consumer and a business. As all potential voters are also consumers, consumer protection has a clear political significance. Concern over the interests of consumers has spawned consumer activism, where organized activists do research, education and advocacy to improve the offer of products and services. Consumer education has |
and succulent in many species. Other species of cactus with long-lasting leaves, such as the opuntioid Pereskiopsis, also have succulent leaves. A key issue in retaining water is the ratio of surface area to volume. Water loss is proportional to surface area, whereas the amount of water present is proportional to volume. Structures with a high surface area-to-volume ratio, such as thin leaves, necessarily lose water at a higher rate than structures with a low area-to-volume ratio, such as thickened stems. Spines, which are modified leaves, are present on even those cacti with true leaves, showing the evolution of spines preceded the loss of leaves. Although spines have a high surface area-to-volume ratio, at maturity they contain little or no water, being composed of fibers made up of dead cells. Spines provide protection from herbivores and camouflage in some species, and assist in water conservation in several ways. They trap air near the surface of the cactus, creating a moister layer that reduces evaporation and transpiration. They can provide some shade, which lowers the temperature of the surface of the cactus, also reducing water loss. When sufficiently moist air is present, such as during fog or early morning mist, spines can condense moisture, which then drips onto the ground and is absorbed by the roots. Stems The majority of cacti are stem succulents, i.e., plants in which the stem is the main organ used to store water. Water may form up to 90% of the total mass of a cactus. Stem shapes vary considerably among cacti. The cylindrical shape of columnar cacti and the spherical shape of globular cacti produce a low surface area-to-volume ratio, thus reducing water loss, as well as minimizing the heating effects of sunlight. The ribbed or fluted stems of many cacti allow the stem to shrink during periods of drought and then swell as it fills with water during periods of availability. A mature saguaro (Carnegiea gigantea) is said to be able to absorb as much as of water during a rainstorm. The outer layer of the stem usually has a tough cuticle, reinforced with waxy layers, which reduce water loss. These layers are responsible for the grayish or bluish tinge to the stem color of many cacti. The stems of most cacti have adaptations to allow them to conduct photosynthesis in the absence of leaves. This is discussed further below under Metabolism. Roots Many cacti have roots that spread out widely, but only penetrate a short distance into the soil. In one case, a young saguaro only tall had a root system with a diameter of , but no more than deep. Cacti can also form new roots quickly when rain falls after a drought. The concentration of salts in the root cells of cacti is relatively high. All these adaptations enable cacti to absorb water rapidly during periods of brief or light rainfall. Thus, Ferocactus cylindraceus reportedly can take up a significant amount of water within 12 hours of as little as of rainfall, becoming fully hydrated in a few days. Although in most cacti, the stem acts as the main organ for storing water, some cacti have in addition large taproots. These may be several times the length of the above-ground body in the case of species such as Copiapoa atacamensis, which grows in one of the driest places in the world, the Atacama Desert in northern Chile. Metabolism Photosynthesis requires plants to take in carbon dioxide gas (). As they do so, they lose water through transpiration. Like other types of succulents, cacti reduce this water loss by the way in which they carry out photosynthesis. "Normal" leafy plants use the C3 mechanism: during daylight hours, is continually drawn out of the air present in spaces inside leaves and converted first into a compound containing three carbon atoms (3-phosphoglycerate) and then into products such as carbohydrates. The access of air to internal spaces within a plant is controlled by stomata, which are able to open and close. The need for a continuous supply of during photosynthesis means the stomata must be open, so water vapor is continuously being lost. Plants using the C3 mechanism lose as much as 97% of the water taken up through their roots in this way. A further problem is that as temperatures rise, the enzyme that captures starts to capture more and more oxygen instead, reducing the efficiency of photosynthesis by up to 25%. Crassulacean acid metabolism (CAM) is a mechanism adopted by cacti and other succulents to avoid the problems of the C3 mechanism. In full CAM, the stomata open only at night, when temperatures and water loss are lowest. enters the plant and is captured in the form of organic acids stored inside cells (in vacuoles). The stomata remain closed throughout the day, and photosynthesis uses only this stored . CAM uses water much more efficiently at the price of limiting the amount of carbon fixed from the atmosphere and thus available for growth. CAM-cycling is a less water-efficient system whereby stomata open in the day, just as in plants using the C3 mechanism. At night, or when the plant is short of water, the stomata close and the CAM mechanism is used to store produced by respiration for use later in photosynthesis. CAM-cycling is present in Pereskia species. By studying the ratio of 14C to 13C incorporated into a plant—its isotopic signature—it is possible to deduce how much is taken up at night and how much in the daytime. Using this approach, most of the Pereskia species investigated exhibit some degree of CAM-cycling, suggesting this ability was present in the ancestor of all cacti. Pereskia leaves are claimed to only have the C3 mechanism with CAM restricted to stems. More recent studies show that "it is highly unlikely that significant carbon assimilation occurs in the stem"; Pereskia species are described as having "C3 with inducible CAM." Leafless cacti carry out all their photosynthesis in the stem, using full CAM. , it is not clear whether stem-based CAM evolved once only in the core cacti, or separately in the opuntias and cactoids; CAM is known to have evolved convergently many times. To carry out photosynthesis, cactus stems have undergone many adaptations. Early in their evolutionary history, the ancestors of modern cacti (other than Leuenbergeria species) developed stomata on their stems and began to delay developing bark. However, this alone was not sufficient; cacti with only these adaptations appear to do very little photosynthesis in their stems. Stems needed to develop structures similar to those normally found only in leaves. Immediately below the outer epidermis, a hypodermal layer developed made up of cells with thickened walls, offering mechanical support. Air spaces were needed between the cells to allow carbon dioxide to diffuse inwards. The center of the stem, the cortex, developed "chlorenchyma" – a plant tissue made up of relatively unspecialized cells containing chloroplasts, arranged into a "spongy layer" and a "palisade layer" where most of the photosynthesis occurs. Taxonomy and classification Naming and classifying cacti has been both difficult and controversial since the first cacti were discovered for science. The difficulties began with Carl Linnaeus. In 1737, he placed the cacti he knew into two genera, Cactus and Pereskia. However, when he published Species Plantarum in 1753—the starting point for modern botanical nomenclature—he relegated them all to one genus, Cactus. The word "cactus" is derived through Latin from the Ancient Greek (kaktos), a name used by Theophrastus for a spiny plant, which may have been the cardoon (Cynara cardunculus). Later botanists, such as Philip Miller in 1754, divided cacti into several genera, which, in 1789, Antoine Laurent de Jussieu placed in his newly created family Cactaceae. By the early 20th century, botanists came to feel Linnaeus's name Cactus had become so confused as to its meaning (was it the genus or the family?) that it should not be used as a genus name. The 1905 Vienna botanical congress rejected the name Cactus and instead declared Mammillaria was the type genus of the family Cactaceae. It did, however, conserve the name Cactaceae, leading to the unusual situation in which the family Cactaceae no longer contains the genus after which it was named. The difficulties continued, partly because giving plants scientific names relies on "type specimens". Ultimately, if botanists want to know whether a particular plant is an example of, say, Mammillaria mammillaris, they should be able to compare it with the type specimen to which this name is permanently attached. Type specimens are normally prepared by compression and drying, after which they are stored in herbaria to act as definitive references. However, cacti are very difficult to preserve in this way; they have evolved to resist drying and their bodies do not easily compress. A further difficulty is that many cacti were given names by growers and horticulturalists rather than botanists; as a result, the provisions of the International Code of Nomenclature for algae, fungi, and plants (which governs the names of cacti, as well as other plants) were often ignored. Curt Backeberg, in particular, is said to have named or renamed 1,200 species without one of his names ever being attached to a specimen, which, according to David Hunt, ensured he "left a trail of nomenclatural chaos that will probably vex cactus taxonomists for centuries." Classification In 1984, it was decided that the Cactaceae Section of the International Organization for Succulent Plant Study should set up a working party, now called the International Cactaceae Systematics Group (ICSG), to produce consensus classifications down to the level of genera. Their system has been used as the basis of subsequent classifications. Detailed treatments published in the 21st century have divided the family into around 125–130 genera and 1,400–1,500 species, which are then arranged into a number of tribes and subfamilies. The ICSG classification of the cactus family recognized four subfamilies, the largest of which was divided into nine tribes. The subfamilies were: Subfamily Pereskioideae K. Schumann The only genus in the ICSG classification was Pereskia. It has features considered closest to the ancestors of the Cactaceae. Plants are trees or shrubs with leaves; their stems are smoothly round in cross section, rather than being ribbed or having tubercles. Two systems may be used in photosynthesis, both the "normal" C3 mechanism and crassulean acid metabolism (CAM)—an "advanced" feature of cacti and other succulents that conserves water. Molecular phylogenetic studies showed that when broadly circumscribed, Pereskia was not monophyletic, and it has been split into three genera, Leuenbergeria, Rhodocactus and a narrowly circumscribed Pereskia. Leuenbergeria is then placed on its own in a separate monogeneric subfamily, Leuenbergerioideae. Subfamily Opuntioideae K. Schumann Some 15 genera are included in this subfamily. They may have leaves when they are young, but these are lost later. Their stems are usually divided into distinct "joints" or "pads" (cladodes). Plants vary in size from the small cushions of Maihueniopsis to treelike species of Opuntia, rising to or more. Subfamily Maihuenioideae P. Fearn The only genus is Maihuenia, with two species, both of which form low-growing mats. It has some features that are primitive within the cacti. Plants have leaves, and crassulean acid metabolism is wholly absent. Subfamily Cactoideae Divided into nine tribes, this is the largest subfamily, including all the "typical" cacti. Members are highly variable in habit, varying from tree-like to epiphytic. Leaves are normally absent, although sometimes very reduced leaves are produced by young plants. Stems are usually not divided into segments, and are ribbed or tuberculate. Two of the tribes, Hylocereeae and Rhipsalideae, contain climbing or epiphytic forms with a rather different appearance; their stems are flattened and may be divided into segments. Molecular phylogenetic studies have supported the monophyly of three of these subfamilies (not Pereskioideae), but have not supported all of the tribes or even genera below this level; indeed, a 2011 study found only 39% of the genera in the subfamily Cactoideae sampled in the research were monophyletic. Classification of the cacti currently remains uncertain and is likely to change. Phylogeny and evolution Phylogeny A 2005 study suggested the genus Pereskia as then circumscribed (Pereskia sensu lato) was basal within the Cactaceae, but confirmed earlier suggestions it was not monophyletic, i.e., did not include all the descendants of a common ancestor. The Bayesian consensus cladogram from this study is shown below with subsequent generic changes added. A 2011 study using fewer genes but more species also found that Pereskia s.l. was divided into the same clades, but was unable to resolve the members of the "core cacti" clade. It was accepted that the relationships shown above are "the most robust to date." Leuenbergeria species (Pereskia s.l. Clade A) always lack two key features of the stem present in most of the remaining "caulocacti": like most non-cacti, their stems begin to form bark early in the plants' life and also lack stomata—structures that control admission of air into a plant and hence control photosynthesis. By contrast, caulocacti, including species of Rhodocactus and the remaining species of Pereskia s.s., typically delay forming bark and have stomata on their stems, thus giving the stem the potential to become a major organ for photosynthesis. (The two highly specialized species of Maihuenia are something of an exception.) The first cacti are thought to have been only slightly succulent shrubs or small trees whose leaves carried out photosynthesis. They lived in tropical areas that experienced periodic drought. If Leuenbergeria is a good model of these early cacti, then, although they would have appeared superficially similar to other trees growing nearby, they had already evolved strategies to conserve water (some of which are present in members of other families in the order Caryophyllales). These strategies included being able to respond rapidly to periods of rain, and keeping transpiration low by using water very efficiently during photosynthesis. The latter was achieved by tightly controlling the opening of stomata. Like Pereskia species today, early ancestors may have been able to switch from the normal C3 mechanism, where carbon dioxide is used continuously in photosynthesis, to CAM cycling, in which when the stomata are closed, carbon dioxide produced by respiration is stored for later use in photosynthesis. The clade containing Rhodocactus and Pereskia s.s. marks the beginnings of an evolutionary switch to using stems as photosynthetic organs. Stems have stomata and the formation of bark takes place later than in normal trees. The "core cacti" show a steady increase in both stem succulence and photosynthesis accompanied by multiple losses of leaves, more-or-less complete in the Cactoideae. One evolutionary question at present unanswered is whether the switch to full CAM photosynthesis in stems occurred only once in the core cacti, in which case it has been lost in Maihuenia, or separately in Opuntioideae and Cactoideae, in which case it never evolved in Maihuenia. Understanding evolution within the core cacti clade is difficult , since phylogenetic relationships are still uncertain and not well related to current classifications. Thus, a 2011 study found "an extraordinarily high proportion of genera" were not monophyletic, so were not all descendants of a single common ancestor. For example, of the 36 genera in the subfamily Cactoideae sampled in the research, 22 (61%) were found not monophyletic. Nine tribes are recognized within Cactoideae in the International Cactaceae Systematics Group (ICSG) classification; one, Calymmantheae, comprises a single genus, Calymmanthium. Only two of the remaining eight – Cacteae and Rhipsalideae – were shown to be monophyletic in a 2011 study by Hernández-Hernández et al.

For a more detailed discussion of the phylogeny of the cacti, see Classification of the Cactaceae. Evolutionary history No known fossils of cacti exist to throw light on their evolutionary history. However, the geographical distribution of cacti offers some evidence. Except for a relatively recent spread of Rhipsalis baccifera to parts of the Old World, cacti are plants of South America and mainly southern regions of North America. This suggests the family must have evolved after the ancient continent of Gondwana split into South America and Africa, which occurred during the Early Cretaceous, around . Precisely when after this split cacti evolved is less clear. Older sources suggest an early origin around 90 – 66 million years ago, during the Late Cretaceous. More recent molecular studies suggest a much younger origin, perhaps in very Late Eocene to early Oligocene periods, around 35–30 million years ago. Based on the phylogeny of the cacti, the earliest diverging group (Leuenbergeria) may have originated in Central America and northern South America, whereas the caulocacti, those with more-or-less succulent stems, evolved later in the southern part of South America, and then moved northwards. Core cacti, those with strongly succulent stems, are estimated to have evolved around 25 million years ago. A possible stimulus to their evolution may have been uplifting in the central Andes, some 25–20 million years ago, which was associated with increasing and varying aridity. However, the current species diversity of cacti is thought to have arisen only in the last 10–5 million years (from the late Miocene into the Pliocene). Other succulent plants, such as the Aizoaceae in South Africa, the Didiereaceae in Madagascar and the genus Agave in the Americas, appear to have diversified at the same time, which coincided with a global expansion of arid environments. Distribution Cacti inhabit diverse regions, from coastal plains to high mountain areas. With one exception, they are native to the Americas, where their range extends from Patagonia to British Columbia and Alberta in western Canada. A number of centers of diversity exist. For cacti adapted to drought, the three main centers are Mexico and the southwestern United States; the southwestern Andes, where they are found in Peru, Bolivia, Chile and Argentina; and eastern Brazil, away from the Amazon Basin. Tree-living epiphytic and climbing cacti necessarily have different centers of diversity, as they require moister environments. They are mainly found in the coastal mountains and Atlantic forests of southeastern Brazil; in Bolivia, which is the center of diversity for the subfamily Rhipsalideae; and in forested regions of Central America, where the climbing Hylocereeae are most diverse. Rhipsalis baccifera is the exception; it is native to both the Americas and the Old World, where it is found in tropical Africa, Madagascar, and Sri Lanka. One theory is it was spread by being carried as seeds in the digestive tracts of migratory birds; the seeds of Rhipsalis are adapted for bird distribution. Old World populations are polyploid, and regarded as distinct subspecies, supporting the idea that the spread was not recent. The alternative theory is the species initially crossed the Atlantic on European ships trading between South America and Africa, after which birds may have spread it more widely. Naturalized species Many other species have become naturalized outside the Americas after having been introduced by people, especially in Australia, Hawaii, and the Mediterranean region. In Australia, species of Opuntia, particularly Opuntia stricta, were introduced in the 19th century for use as natural agricultural fences and in an attempt to establish a cochineal industry. They rapidly became a major weed problem, but are now controlled by biological agents, particularly the moth Cactoblastis cactorum. The weed potential of Opuntia species in Australia continues however, leading to all opuntioid cacti except O. ficus-indica being declared Weeds of National Significance by the Australian Weeds Committee in April 2012. The Arabian Peninsula has a wide variety of ever-increasing, introduced cactus populations. Some of these are cultivated, some are escapes from cultivation, and some are invasives that are presumed to be ornamental escapes. Reproductive ecology Cactus flowers are pollinated by insects, birds and bats. None are known to be wind-pollinated and self-pollination occurs in only a very few species; for example the flowers of some species of Frailea do not open (cleistogamy). The need to attract pollinators has led to the evolution of pollination syndromes, which are defined as groups of "floral traits, including rewards, associated with the attraction and utilization of a specific group of animals as pollinators." Bees are the most common pollinators of cacti; bee-pollination is considered to have been the first to evolve. Day-flying butterflies and nocturnal moths are associated with different pollination syndromes. Butterfly-pollinated flowers are usually brightly colored, opening during the day, whereas moth-pollinated flowers are often white or pale in color, opening only in the evening and at night. As an example, Lophocereus schottii is pollinated by a particular species of moth, Upiga virescens, which also lays its eggs among the developing seeds its caterpillars later consume. The flowers of this cactus are funnel-shaped, white to deep pink, up to long, and open at night. Hummingbirds are significant pollinators of cacti. Species showing the typical hummingbird-pollination syndrome have flowers with colors towards the red end of the spectrum, anthers and stamens that protrude from the flower, and a shape that is not radially symmetrical, with a lower lip that bends downwards; they produce large amounts of nectar with a relatively low sugar content. Schlumbergera species, such as S. truncata, have flowers that correspond closely to this syndrome. Other hummingbird-pollinated genera include Cleistocactus and Disocactus. Bat-pollination is relatively uncommon in flowering plants, but about a quarter of the genera of cacti are known to be pollinated by bats—an unusually high proportion, exceeded among eudicots by only two other families, both with very few genera. Columnar cacti growing in semidesert areas are among those most likely to be bat-pollinated; this may be because bats are able to travel considerable distances, so are effective pollinators of plants growing widely separated from one another. The pollination syndrome associated with bats includes a tendency for flowers to open in the evening and at night, when bats are active. Other features include a relatively dull color, often white or green; a radially symmetrical shape, often tubular; a smell described as "musty"; and the production of a large amount of sugar-rich nectar. Carnegiea gigantea is an example of a bat-pollinated cactus, as are many species of Pachycereus and Pilosocereus. The fruits produced by cacti after the flowers have been fertilized vary considerably; many are fleshy, although some are dry. All contain a large number of seeds. Fleshy, colorful and sweet-tasting fruits are associated with seed dispersal by birds. The seeds pass through their digestive systems and are deposited in their droppings. Fruit that falls to the ground may be eaten by other animals; giant tortoises are reported to distribute Opuntia seeds in the Galápagos Islands. Ants appear to disperse the seeds of a few genera, such as Blossfeldia. Drier spiny fruits may cling to the fur of mammals or be moved around by the wind. Uses Early history , there is still controversy as to the precise dates when humans first entered those areas of the New World where cacti are commonly found, and hence when they might first have used them. An archaeological site in Chile has been dated to around 15,000 years ago, suggesting cacti would have been encountered before then. Early evidence of the use of cacti includes cave paintings in the Serra da Capivara in Brazil, and seeds found in ancient middens (waste dumps) in Mexico and Peru, with dates estimated at 12,000–9,000 years ago. Hunter-gatherers likely collected cactus fruits in the wild and brought them back to their camps. It is not known when cacti were first cultivated. Opuntias (prickly pears) were used for a variety of purposes by the Aztecs, whose empire, lasting from the 14th to the 16th century, had a complex system of horticulture. Their capital from the 15th century was Tenochtitlan (now Mexico City); one explanation for the origin of the name is that it includes the Nahuatl word nōchtli, referring to the fruit of an opuntia. The coat of arms of Mexico shows an eagle perched on a cactus while holding a snake, an image at the center of the myth of the founding of Tenochtitlan. The Aztecs symbolically linked the ripe red fruits of an opuntia to human hearts; just as the fruit quenches thirst, so offering human hearts to the sun god ensured the sun would keep moving. Europeans first encountered cacti when they arrived in the New World late in the 15th century. Their first landfalls were in the West Indies, where relatively few cactus genera are found; one of the most common is the genus Melocactus. Thus, melocacti were possibly among the first cacti seen by Europeans. Melocactus species were present in English collections of cacti before the end of the 16th century (by 1570 according to one source,) where they were called Echinomelocactus, later shortened to Melocactus by Joseph Pitton de Tourneville in the early 18th century. Cacti, both purely ornamental species and those with edible fruit, continued to arrive in Europe, so Carl Linnaeus was able to name 22 species by 1753. One of these, his Cactus opuntia (now part of Opuntia ficus-indica), was described as "" (with larger fruit ... now in Spain and Portugal), indicative of its early use in Europe. Food The plant now known as Opuntia ficus-indica, or the Indian fig cactus, has long been an important source of food. The original species is thought to have come from central Mexico, although this is now obscure because the indigenous people of southern North America developed and distributed a range of horticultural varieties (cultivars), including forms of the species and hybrids with other opuntias.

CCC tried to build "better men" who would be economically independent and self-reliant. By 1939, there was a shift in the ideal from the hardy manual worker to the highly trained citizen soldier ready for war. Early years, 1933–1937 The legislation and mobilization of the program occurred quite rapidly. Roosevelt made his request to Congress on March 21, 1933; the legislation was submitted to Congress the same day; Congress passed it by voice vote on March 31; Roosevelt signed it the same day, then issued an executive order on April 5 creating the agency, appointing its director (Fechner), and assigning War Department corps area commanders to begin enrollment. The first CCC enrollee was selected April 8, and subsequent lists of unemployed men were supplied by state and local welfare and relief agencies for immediate enrollment. On April 17, the first camp, NF-1, Camp Roosevelt, was established at George Washington National Forest near Luray, Virginia. On June 18, the first of 161 soil erosion control camps was opened, in Clayton, Alabama. By July 1, 1933, there were 1,463 working camps with 250,000 junior enrollees (18–25 years of age); 28,000 veterans; 14,000 American Indians; and 25,000 adults in the Locally Men (LEM) program. Enrollees The typical CCC enrollee was a U.S. citizen, unmarried, unemployed male, 18–25 years of age. Normally his family was on local relief. Each enrollee volunteered and, upon passing a physical exam and/or a period of conditioning, was required to serve a minimum six-month period, with the option to serve as many as four periods, or up to two years, if employment outside the Corps was not possible. Enrollees worked 40 hours per week over five days, sometimes including Saturdays if poor weather dictated. In return they received $30 per month () with a compulsory allotment of $25 (about ) sent to a family dependent, as well as housing, food, clothing, and medical care. Veterans Conservation Corps Following the second Bonus Army march on Washington, D.C., President Roosevelt amended the CCC program on May 11, 1933, to include work opportunities for veterans. Veteran qualifications differed from the junior enrollee; one needed to be certified by the Veterans Administration by an application. They could be any age, and married or single as long as they were in need of work. Veterans were generally assigned to entire veteran camps. Enrollees were eligible for the following "rated" positions to help with camp administration: senior leader, mess steward, storekeeper and two cooks; assistant leader, company clerk, assistant educational advisor and three second cooks. These men received additional pay ranging from $36 to $45 per month depending on their rating. Camps Each CCC camp was located in the area of particular conservation work to be performed and organized around a complement of up to 200 civilian enrollees in a designated numbered "company" unit. The CCC camp was a temporary community in itself, structured to have barracks (initially Army tents) for 50 enrollees each, officer/technical staff quarters, medical dispensary, mess hall, recreation hall, educational building, lavatory and showers, technical/administrative offices, tool room/blacksmith shop and motor pool garages. The company organization of each camp had a dual-authority supervisory staff: firstly, Department of War personnel or Reserve officers (until July 1, 1939), a "company commander" and junior officer, who were responsible for overall camp operation, logistics, education and training; and secondly, ten to fourteen technical service civilians, including a camp "superintendent" and "foreman", employed by either the Departments of Interior or Agriculture, responsible for the particular fieldwork. Also included in camp operation were several non-technical supervisor LEMs, who provided knowledge of the work at hand, "lay of the land," and paternal guidance for inexperienced enrollees. Enrollees were organized into work detail units called "sections" of 25 men each, according to the barracks they resided in. Each section had an enrollee "senior leader" and "assistant leader" who were accountable for the men at work and in the barracks. Work classifications The CCC performed 300 types of work projects in ten approved general classifications: Structural improvements: bridges, fire lookout towers, service buildings Transportation: truck trails, minor roads, foot trails and airfields Erosion control: check dams, terracing, and vegetable covering Flood control: irrigation, drainage, dams, ditching, channel work, riprapping Forest culture: tree planting, fire prevention, fire pre-suppression, firefighting, insect and disease control Landscape and recreation: public camp and picnic ground development, lake and pond site clearing and development Range: stock driveways, elimination of predatory animals Wildlife: stream improvement, fish stocking, food and cover planting Miscellaneous: emergency work, surveys, mosquito control The responses to this seven-month experimental conservation program were enthusiastic. On October 1, 1933, Director Fechner was directed to arrange for the second period of enrollment. By January 1934, 300,000 men were enrolled. In July 1934, this cap was increased by 50,000 to include men from Midwest states that had been affected by drought. The temporary tent camps had also developed to include wooden barracks. An education program had been established, emphasizing job training and literacy. Approximately 55% of enrollees were from rural communities, a majority of which were non-farm; 45% came from urban areas. Level of education for the enrollee averaged 3% illiterate; 38% had less than eight years of school; 48% did not complete high school; and 11% were high school graduates. At the time of entry, 70% of enrollees were malnourished and poorly clothed. Few had work experience beyond occasional odd jobs. Peace was maintained by the threat of "dishonorable discharge". "This is a training station; we're going to leave morally and physically fit to lick 'Old Man Depression,'" boasted the newsletter, Happy Days, of a North Carolina camp. Minorities Because of the power of conservative Solid South white Democrats in Congress, who insisted on racial segregation, most New Deal programs were racially segregated; blacks and whites rarely worked alongside each other. At this time, all the states of the South had passed legislation imposing racial segregation and, since the turn of the century, laws and constitutional provisions that disenfranchised most blacks; they were excluded from formal politics. Because of discrimination by white officials at the local and state levels, blacks in the South did not receive as many benefits as whites from New Deal programs. In the first few weeks of operation, CCC camps in the North were integrated. By July 1935, however, all camps in the United States were segregated. Enrollment peaked at the end of 1935, when there were 500,000 men in 2,600 camps in operation in every state. All received equal pay and housing. Black leaders lobbied to secure leadership roles. Adult white men held the major leadership roles in all the camps. Director Fechner refused to appoint black adults to any supervisory positions except that of education director in the all-black camps. Indian Division The CCC operated a separate division for members of federally recognized tribes: the "Indian Emergency Conservation Work Division" (IECW or CCC-ID). Native men from reservations worked on roads, bridges, clinics, shelters, and other public works near their reservations. Although they were organized as groups classified as camps, no permanent camps were established for Native Americans. Instead, organized groups moved with their families from project to project and were provided with an additional rental allowance. The CCC often provided the only paid work, as many reservations were in remote rural areas. Enrollees had to be between the ages of 17 and 35. During 1933, about half the male heads of households on the Sioux reservations in South Dakota were employed by the CCC-ID. With grants from the Public Works Administration (PWA), the Indian Division built schools and conducted a road-building program in and around many reservations to improve infrastructure. The mission was to reduce erosion and improve the value of Indian lands. Crews built dams of many types on creeks, then sowed grass on the eroded areas from which the damming material had been taken. They built roads and planted shelter-belts on federal lands. The steady income helped participants regain self-respect, and many used the funds to improve their lives. John Collier, the federal Commissioner of Indian Affairs and Daniel Murphy, the director of the CCC-ID, both based the program on Indian self-rule and the restoration of tribal lands, governments, and cultures. The next year, Congress passed the Indian Reorganization Act of 1934, which ended allotments and helped preserve tribal lands, and encouraged tribes to re-establish self-government. Collier said of the CCC-Indian Division, "no previous undertaking in Indian Service has so largely been the Indians' own undertaking". Educational programs trained participants in gardening, stock raising, safety, native arts, and some academic subjects. IECW differed from other CCC activities in that it explicitly trained men in skills to be carpenters, truck drivers, radio operators, mechanics, surveyors, and technicians. With the passage of the National Defense Vocational Training Act of 1941, enrollees began participating in defense-oriented training. The government paid for the classes and after students completed courses and passed a competency test, guaranteed automatic employment in defense work. A total of 85,000 Native Americans were enrolled in this training. This proved valuable social capital for the 24,000 alumni who later served in the military and the 40,000 who left the reservations for city jobs supporting the war effort. Expansion, 1935–1936 Responding to public demand to alleviate unemployment, Congress approved the Emergency Relief Appropriation Act of 1935, on April 8, 1935, which included continued funding for the CCC program through March 31, 1937. The age limit was expanded to 18–28 to include more men. April 1, 1935, to March 31, 1936, was the period of greatest activity and work accomplished by the CCC program. Enrollment peaked at 505,782 in about 2,900 camps by August 31, 1935, followed by a reduction to 350,000 enrollees in 2,019 camps by June 30, 1936. During this period the public response to the CCC program was overwhelmingly popular. A Gallup poll of April 18, 1936, asked: "Are you in favor of the CCC camps?"; 82% of respondents said "yes", including 92% of Democrats and 67% of Republicans. Change of purpose, 1937–1938 On June 28, 1937, the Civilian Conservation Corps was legally established and transferred from its original designation as the Emergency Conservation Work program. Funding was extended for three more years by Public Law No. 163, 75th Congress, effective July 1, 1937. Congress changed the age limits to 17–23 years old and changed the requirement that enrollees be on relief to "not regularly in attendance at school, or possessing full-time employment." The 1937 law mandated the inclusion of vocational and academic training for a minimum of 10 hours per week. Students in school were allowed to enroll during summer vacation. During this period, the CCC forces contributed to disaster relief following 1937 floods in New York, Vermont, and the Ohio and Mississippi river valleys, and response and clean-up after the 1938 hurricane in New England. From conservation to defense, 1939–1940 In 1939 Congress ended the independent status of the CCC, transferring it to the control of the Federal Security Agency. The National Youth Administration, U.S. Employment Service, the Office of Education, and the Works Progress Administration also had some responsibilities. About 5,000 reserve officers serving in the camps were affected, as they were transferred to federal Civil Service, and military ranks and titles were eliminated. Despite the loss of overt military leadership in the camps by July 1940, with war underway in Europe and Asia, the government directed an increasing number of CCC projects to resources for national defense. It developed infrastructure for military training facilities and forest protection. By 1940 the CCC was no longer wholly a relief agency, was rapidly losing its non-military character, and it was becoming a system for work-training, as its ranks had become increasingly younger and inexperienced. Decline and disbandment 1941–1942 Although the CCC was probably the most popular New Deal program, it never was authorized as a permanent agency. The program was reduced in scale as the Depression waned and employment opportunities improved. After conscription began in 1940, fewer eligible young men were available. Following the attack on Pearl Harbor in December 1941, the Roosevelt administration directed all federal programs to emphasize the war effort. Most CCC work, except for wildland firefighting, was shifted onto U.S. military bases to help with construction. The CCC disbanded one year earlier than planned, as the 77th United States Congress ceased funding it. Operations were formally concluded at the end of the federal fiscal year on June 30, 1942. The end of the CCC program and closing of the camps involved arrangements to leave the incomplete work projects in the best possible state, the separation of about 1,800 appointed employees, the transfer of CCC property to the War and Navy Departments and other agencies, and the preparation of final accountability records. Liquidation of the CCC was ordered by Congress by the Labor-Federal Security Appropriation Act (56 Stat. 569) on July 2, 1942, and virtually completed on June 30, 1943. Liquidation appropriations for the CCC continued through April 20, 1948. Some former CCC sites in good condition were reactivated from 1941 to 1947 as Civilian Public Service camps where conscientious objectors performed "work of national importance" as an alternative to military service. Other camps were used to hold Japanese, German and Italian Americans interned under the Western Defense Command's Enemy Alien Control Program, as well as Axis prisoners of war. Most of the Japanese American internment camps were built by the people held there. After the CCC disbanded, the federal agencies responsible for public lands organized their own seasonal fire crews, modeled after the CCC. These have performed a firefighting function formerly done by the CCC and provided the same sort of outdoor work experience for young people. Approximately 47 young men have died while in this line of duty.

Jeanette Ingold's novel Hitch (2012) is a young adult book about a teenager in the CCC. Inspired programs The CCC program was never officially terminated. Congress provided funding for closing the remaining camps in 1942 with the equipment being reallocated. It became a model for conservation programs that were implemented in the period after World War II. Present-day corps are national, state, and local programs that engage primarily youth and young adults (ages 16–25) in community service, training, and educational activities. The nation's approximately 113 corps programs operate in 41 states and the District of Columbia. During 2004, they enrolled more than 23,000 young people. The Corps Network, known originally as the National Association of Service and Conservation Corps (NASCC), works to expand and enhance corps-type programs throughout the country. The Corps Network began in 1985 when the nation's first 24 Corps directors banded together to secure an advocate at the federal level and a repository of information on how best to start and manage a corps. Early financial assistance from the Ford, Hewlett and Mott Foundations was critical to establishing the association. Similar active programs in the United States are: the National Civilian Community Corps, part of the AmeriCorps program, a team-based national service program in which young adults ages 18–24 spend 10 months working for non-profit and government organizations; and the Civilian Conservation Corps, USA, (CCCUSA) managed by its president, Thomas Hark, in 2016. Hark, his co-founder Mike Rama, currently the Deputy Director of the Corporate Eco Forum (CEF) founded by M. R. Rangaswami, and their team of strategic advisors have reimagined the federal Civilian Conservation Corps program of the 1930s as a private, locally governed, national social franchise. The goal of this recently established CCCUSA is to enroll a million young people annually, building a core set of values in each enrollee, who will then become the catalyst in their own communities and states to create a more civil society and stronger nation. Student Conservation Association The CCC program became a model for the creation of team-based national service youth conservation programs such as the Student Conservation Association (SCA). The SCA, founded in 1959, is a nonprofit | was maintained by the threat of "dishonorable discharge". "This is a training station; we're going to leave morally and physically fit to lick 'Old Man Depression,'" boasted the newsletter, Happy Days, of a North Carolina camp.

About 5,000 reserve officers serving in the camps were affected, as they were transferred to federal Civil Service, and military ranks and titles were eliminated. Despite the loss of overt military leadership in the camps by July 1940, with war underway in Europe and Asia, the government directed an increasing number of CCC projects to resources for national defense. It developed infrastructure for military training facilities and forest protection. By 1940 the CCC was no longer wholly a relief agency, was rapidly losing its non-military character, and it was becoming a system for work-training, as its ranks had become increasingly younger and inexperienced. Decline and disbandment 1941–1942 Although the CCC was probably the most popular New Deal program, it never was authorized as a permanent agency. The program was reduced in scale as the Depression waned and employment opportunities improved. After conscription began in 1940, fewer eligible young men were available. Following the attack on Pearl Harbor in December 1941, the Roosevelt administration directed all federal programs to emphasize the war effort. Most CCC work, except for wildland firefighting, was shifted onto U.S. military bases to help with construction. The CCC disbanded one year earlier than planned, as the 77th United States Congress ceased funding it. Operations were formally concluded at the end of the federal fiscal year on June 30, 1942. The end of the CCC program and closing of the camps involved arrangements to leave the incomplete work projects in the best possible state, the separation of about 1,800 appointed employees, the transfer of CCC property to the War and Navy Departments and other agencies, and the preparation of final accountability records. Liquidation of the CCC was ordered by Congress by the Labor-Federal Security Appropriation Act (56 Stat. 569) on July 2, 1942, and virtually completed on June 30, 1943. Liquidation appropriations for the CCC continued through April 20, 1948. Some former CCC sites in good condition were reactivated from 1941 to 1947 as Civilian Public Service camps where conscientious objectors performed "work of national importance" as an alternative to military service. Other camps were used to hold Japanese, German and Italian Americans interned under the Western Defense Command's Enemy Alien Control Program, as well as Axis prisoners of war. Most of the Japanese American internment camps were built by the people held there. After the CCC disbanded, the federal agencies responsible for public lands organized their own seasonal fire crews, modeled after the CCC. These have performed a firefighting function formerly done by the CCC and provided the same sort of outdoor work experience for young people. Approximately 47 young men have died while in this line of duty.

The American Experience PBS series showcased documentaries on American history; it portrayed the life in Civilian Conservation Corps in 2009, in the first episode of Season 22. Jeanette Ingold's novel Hitch (2012) is a young adult book about a teenager in the CCC. Inspired programs The CCC program was never officially terminated. Congress provided funding for closing the remaining camps in 1942 with the equipment being reallocated. It became a model for conservation programs that were implemented in the period after World War II. Present-day corps are national, state, and local programs that engage primarily youth and young adults (ages 16–25) in community service, training, and educational activities. The nation's approximately 113 corps programs operate in 41 states and the District of Columbia. During 2004, they enrolled more than 23,000 young people. The Corps Network, known originally as the National Association of Service and Conservation Corps (NASCC), works to expand and enhance corps-type programs throughout the country. The Corps Network began in 1985 when the nation's first 24 Corps directors banded together to secure an advocate at the federal level and a repository of information on how best to start and manage a corps. Early financial assistance from the Ford, Hewlett and Mott Foundations was critical to establishing the association. Similar active programs in the United States are: the National Civilian Community Corps, part of the AmeriCorps program, a team-based national service program in which young adults ages 18–24 spend 10 months working for non-profit and government organizations; and the Civilian Conservation Corps, USA, (CCCUSA) managed by its president, Thomas Hark, in 2016. Hark, his co-founder Mike Rama, currently the Deputy Director of the Corporate Eco Forum (CEF) founded by M. R. Rangaswami, and their team of strategic advisors have reimagined the federal Civilian Conservation Corps program of the 1930s as a private, locally governed, national social franchise. The goal of this recently established CCCUSA is to enroll a million young people annually, building a core set of values in each enrollee, who will then become the catalyst in their own communities and states to create a more civil society and stronger nation. Student Conservation Association The CCC program became a model for the creation of team-based national service youth conservation programs such as the Student Conservation Association (SCA). The SCA, founded in 1959, is a nonprofit organization that offers conservation internships and summer trail crew opportunities to more than 4,000 people each year. California Conservation Corps In 1976, Governor of California Jerry Brown established the California Conservation Corps. This program had many similar characteristics - residential centers, high expectations for participation, and emphasis on hard work on public lands. Young adults from different backgrounds were recruited for a term of one year. Corps members attended a training session called the Corpsmember Orientation Motivation Education and Training (COMET) program before being assigned to one of the various centers. Project work is also similar to the original CCC of the 1930s - work on public forests, state and federal parks. Nevada Conservation Corps The Nevada Conservation Corps is a non-profit organization that partners with public land management agencies such as the Bureau of Land Management, United States Forest Service, National Park Service, and Nevada State Parks to complete conservation and restoration projects throughout Nevada. Conservation work includes fuel reductions through thinning, constructing and maintaining trails, invasive species removal, and performing biological surveys. The Nevada Conservation Corps was created through the Great Basin Institute and is part of the AmeriCorps program. Minnesota Conservation Corps Conservation Corps Minnesota & Iowa provides environmental stewardship and service-learning opportunities to youth and young adults while accomplishing conservation, natural resource management projects and emergency response work through its Young Adult Program and the Summer Youth Program. These programs emphasize the development of job and life skills by conservation and community service work. Montana Conservation Corps The Montana Conservation Corps (MCC) is a non-profit organization with a mission to equip young people with the skills and values to be vigorous citizens who improve their communities and environment. Collectively, MCC crews contribute more than 90,000 work hours each year. The MCC was established in 1991 by Montana's Human Resource Development Councils in Billings, Bozeman and Kalispell. Originally, it was a summer program for disadvantaged youth, although it has grown into an AmeriCorps-sponsored non-profit organization with six regional offices that serve Montana, Idaho, Wyoming, North Dakota, and South Dakota.

There was a very serious eruption of Mount Pelée in 1902 which caused many casualties. The Caribbean sea floor is also home to two oceanic trenches: the Cayman Trench and Puerto Rico Trench, which put the area at a high risk of earthquakes. Underwater earthquakes pose a threat of generating tsunamis which could have a devastating effect on the Caribbean islands. Scientific data reveals that over the last 500 years the area has seen a dozen earthquakes above 7.5 magnitude. Most recently, a 7.1 earthquake struck Haiti on January 12, 2010. List of islands in the Caribbean Oceanography The hydrology of the sea has a high level of homogeneity. Annual variations in monthly average water temperatures at the surface do not exceed . Over the past fifty years the Caribbean has gone through three stages: cooling until 1974; a cold phase with peaks during 1974–1976 and 1984–1986 then; a warming phase with an increase in temperature of per year. Virtually all temperature extremes were associated with the phenomena of El Niño and La Niña. The salinity of seawater is about 3.6% and its density is . The surface water colour is blue-green to green. The Caribbean's depth in its wider basins and deep water temperatures are similar to those of the Atlantic. Atlantic deep water is thought to spill into the Caribbean and contribute to the general deep water of its sea. The surface water (30 m; 100 feet) acts as an extension of the northern Atlantic as the Guiana Current and part of the North Equatorial Current enter the sea on the east. On the western side of the sea the trade winds influence a northerly current which causes an upwelling and a rich fishery near Yucatán. Ecology The Caribbean is home to about 9% of the world's coral reefs covering about , most of which are located off the Caribbean Islands and the Central American coast. Among them stands out the Belize Barrier Reef with an area of which was declared a World Heritage Site in 1996. It forms part of the Great Mayan Reef also known as the MBRS and being over in length is the world's second longest. It runs along the Caribbean coasts of Mexico, Belize, Guatemala and Honduras. During the past ten years, unusually warm Caribbean waters have been increasingly threatening Caribbean coral reefs. Coral reefs support some of the most diverse marine habitats in the world, but they are fragile ecosystems. When tropical waters become unusually warm for extended periods of time, microscopic plants called zooxanthellae, which are symbiotic partners living within the coral polyp tissues, die off. These plants provide food for the corals and give them their color. The result of the death and dispersal of these tiny plants is called coral bleaching, and can lead to the devastation of large areas of reef. Over 42% of corals are completely bleached and 95% are experiencing some type of whitening. Historically the Caribbean is thought to contain 14% of the world's coral reefs. The habitats supported by the reefs are critical to such tourist activities as fishing and diving, and provide an annual economic value to Caribbean nations of US$3.1–4.6 billion. Continued destruction of the reefs could severely damage the region's economy. A Protocol of the Convention for the Protection and Development of the Marine Environment of the Wider Caribbean Region came in effect in 1986 to protect the various endangered marine life of the Caribbean through forbidding human activities that would advance the continued destruction of such marine life in various areas. Currently this protocol has been ratified by 15 countries. Also, several charitable organisations have been formed to preserve the Caribbean marine life, such as Caribbean Conservation Corporation which seeks to study and protect sea turtles while educating others about them. In connection with the foregoing, the Institute of Marine Sciences and Limnology of the National Autonomous University of Mexico, conducted a regional study, funded by the Department of Technical Cooperation of the International Atomic Energy Agency, in which specialists from 11 Latin American countries (Colombia, Costa Rica, Cuba, Guatemala, Haiti, Honduras, Mexico, Nicaragua, Panama, Dominican Republic, Venezuela) plus Jamaica participated. The findings indicate that heavy metals such as mercury, arsenic, and lead, have been identified in the coastal zone of the Caribbean Sea. Analysis of toxic metals and hydrocarbons is based on the investigation of coastal sediments that have accumulated less than 50 meters deep during the last hundred and fifty years. The project results were presented in Vienna in the forum "Water Matters", and the 2011 General Conference of said multilateral organization. Climate The climate of the Caribbean is driven by the low latitude and tropical ocean currents that run through it. The principal ocean current is the North Equatorial Current, which enters the region from the tropical Atlantic. The climate of the area is tropical, varying from tropical rainforest in some areas to tropical savanna in others. There are also some locations that are arid climates with considerable drought in some years. Rainfall varies with elevation, size, and water currents (cool upwelling keep the ABC islands arid). Warm, moist trade winds blow consistently from the east, creating both rainforest and semi-arid climates across the region. The tropical rainforest climates include lowland areas near the Caribbean Sea from Costa Rica north to Belize, as well as the Dominican Republic and Puerto Rico, while the more seasonal dry tropical savanna climates are found in Cuba, northern Venezuela, and southern Yucatán, Mexico. Arid climates are found along the extreme southern coast of Venezuela out to the islands including Aruba and Curaçao, as well as the northern tip of Yucatán Tropical cyclones are a threat to the nations that rim the Caribbean Sea. While landfalls are infrequent, the resulting loss of life and property damage makes them a significant hazard to life in the Caribbean. Tropical cyclones that impact the Caribbean often develop off the West coast of Africa and make their way west across the Atlantic Ocean toward the Caribbean, while other storms develop in the Caribbean itself. The Caribbean hurricane season as a whole lasts from June through November, with the majority of hurricanes occurring during August and September. On average around 9 tropical storms form each year, with 5 reaching hurricane strength. According to the National Hurricane Center 385 hurricanes occurred in the Caribbean between 1494 and 1900. Flora and fauna The region has a high level of biodiversity and many species are endemic to the Caribbean. Vegetation The vegetation of the region is mostly tropical but differences in topography, soil and climatic conditions increase species diversity. Where there are porous limestone terraced islands these are generally poor in nutrients. It is estimated that 13,000 species of plants grow in the Caribbean of which 6,500 are endemic.

The mahogany is the national tree of the Dominican Republic and Belize. The caimito (Chrysophyllum cainito) grows throughout the Caribbean. In coastal zones there are coconut palms and in lagoons and estuaries are found thick areas of black mangrove and red mangrove (Rhizophora mangle). In shallow water flora and fauna is concentrated around coral reefs where there is little variation in water temperature, purity and salinity. Leeward side of lagoons provide areas of growth for sea grasses. Turtle grass (Thalassia testudinum) is common in the Caribbean as is manatee grass (Syringodium filiforme) which can grow together as well as in fields of single species at depths up to . Another type shoal grass (Halodule wrightii) grows on sand and mud surfaces at depths of up to . In brackish water of harbours and estuaries at depths less than widgeongrass (Ruppia maritima) grows. Representatives of three species belonging to the genus Halophila, (Halophila baillonii, Halophila engelmannii and Halophila decipiens) are found at depths of up to except for Halophila engelmani which does not grow below and is confined to the Bahamas, Florida, the Greater Antilles and the western part of the Caribbean. Halophila baillonii has been found only in the Lesser Antilles. Fauna Marine biota in the region have representatives of both the Indian and Pacific oceans which were caught in the Caribbean before the emergence of the Isthmus of Panama four million years ago.

Royal Society. In 1722, having provided a locum for his class at Aberdeen, he travelled on the Continent as tutor to George Hume, the son of Alexander Hume, 2nd Earl of Marchmont. During their time in Lorraine, he wrote his essay on the percussion of bodies (Demonstration des loix du choc des corps), which gained the prize of the Royal Academy of Sciences in 1724. Upon the death of his pupil at Montpellier, Maclaurin returned to Aberdeen. In 1725, Maclaurin was appointed deputy to the mathematical professor at the University of Edinburgh, James Gregory (brother of David Gregory and nephew of the esteemed James Gregory), upon the recommendation of Isaac Newton. On 3 November of that year Maclaurin succeeded Gregory, and went on to raise the character of that university as a school of science. Newton was so impressed with Maclaurin that he had offered to pay his salary himself. Contributions to mathematics Maclaurin used Taylor series to characterize maxima, minima, and points of inflection for infinitely differentiable functions in his Treatise of Fluxions. Maclaurin attributed the series to Brook Taylor, though the series was known before to Newton and Gregory, and in special cases to Madhava of Sangamagrama in fourteenth century India. Nevertheless, Maclaurin received credit for his use of the series, and the Taylor series expanded around 0 is sometimes known as the Maclaurin series. Maclaurin also made significant contributions to the gravitation attraction of ellipsoids, a subject that furthermore attracted the attention of d'Alembert, A.-C. Clairaut, Euler, Laplace, Legendre, Poisson and Gauss. Maclaurin showed that an oblate spheroid was a possible equilibrium in Newton's theory of gravity. The subject continues to be of scientific interest, and Nobel Laureate Subramanyan Chandrasekhar dedicated a chapter of his book Ellipsoidal Figures of Equilibrium to Maclaurin spheroids. Independently from Euler and using the same methods, Maclaurin discovered the Euler–Maclaurin formula. He used it to sum powers of arithmetic progressions, derive Stirling's formula, and to derive the Newton-Cotes numerical integration formulas which includes Simpson's rule as a special case. Maclaurin contributed to the study of elliptic integrals, reducing many intractable integrals to problems of finding arcs for hyperbolas. His work was continued by d'Alembert and Euler, who gave a more concise approach. In his Treatise of Algebra (Ch. XII, Sect 86), published in 1748 two years after his death, Maclaurin proved a rule for solving square linear systems in the cases of 2 and 3 unknowns, and discussed the case of 4 unknowns.

Personal life In 1733, Maclaurin married Anne Stewart, the daughter of Walter Stewart, the Solicitor General for Scotland, by whom he had seven children. His eldest son John Maclaurin studied Law, was a Senator of the College of Justice, and became Lord Dreghorn; he was also joint founder of the Royal Society of Edinburgh. Maclaurin actively opposed the Jacobite rising of 1745 and superintended the operations necessary for the defence of Edinburgh against the Highland army. Maclaurin compiled a diary of his exertions against the Jacobites, both within and without the city. When the Highland army entered the city, however, he fled to York, where he was invited to stay by the Archbishop of York. On his journey south, Maclaurin fell from his horse, and the fatigue, anxiety, and cold to which he was exposed on that occasion laid the foundations of dropsy. He returned to Edinburgh after the Jacobite army |
of the celestial sphere, whereas the celestial globe is orthographic projection as viewed from the outside. For this reason, celestial globes are often produced in mirror image, so that at least the constellations appear as viewed from earth. Some modern celestial globes address this problem by making the surface of the globe transparent. The stars can then be placed in their proper positions and viewed through the globe, so that the view is of the inside of the celestial sphere. However, the proper position from which to view the sphere would be from its centre, but the viewer of a transparent globe must be outside it, far from its centre. Viewing the inside of the sphere from the outside, through its transparent surface, produces serious distortions. Opaque celestial globes that are made with the constellations correctly placed, so they appear as mirror images when directly viewed from outside the globe, are often viewed in a mirror, so the constellations have their familiar appearances. Written material on the globe, e.g. constellation names, is printed in reverse, so it can easily be read in the mirror. Before Copernicus’s 16th century discovery that the solar system is ‘heliocentric rather than geocentric and geostatic’ (that the earth orbits the sun and not the other way around) ‘the stars have been commonly, though perhaps not universally, perceived as though attached to the inside of a hollow sphere enclosing and rotating about the earth’. Working under the incorrect assumption that the cosmos was geocentric the second century Greek astronomer Ptolemy composed the Almagest in which ‘the movements of the planets could be accurately represented by means of techniques involving the use of epicycles, deferents, eccentrics (whereby planetary motion is conceived as circular with respect to a point displaced from Earth), and equants (a device that posits a constant angular rate of rotation with respect to a point displaced from Earth)’. | on how the globe should be decorated, suggesting ‘the sphere a dark colour resembling the night sky’. Al-Sufi - The Book of the Constellations Al-sufi (Abu'l-Husayn 'Abd al-Rahman ibn 'Umar al-Sufi) was an important 10th century astronomer whose works were instrumental in the Islamic development of the Celestial Globe. His Books, The Book of the Constellations, (‘designed to be accurate for the year 964 (353 AH)’ ) was a ‘description of the constellations that combines Greek/ Ptolemaic traditions with Arabic/Bedouin ones’. The Book of the Constellations then served as an important source of star coordinates for makers of astrolabes and globes across the Islamic world. Similarly this ‘treatise was instrumental in displacing the traditional Bedouin constellation imagery and replacing it with the Greek/Ptolemaic system which ultimately came to dominate all astronomy’. Earliest example – 11th century The earliest surviving Celestial Globe was made between 1080 and 1085 C.E by Ibrahim ibn Said al-Sahli, a well known astrolabe maker working in Valencia, Spain. Although the imagery on this globe appears to be unrelated to that in al-Sufi’s The Book of the Constellations al-Wazzan does seem to have been aware of this work as ‘all forty-eight of the classical Greek constellations are illustrated on the globe, just as in al-Sufi's treatise, with the stars indicated by circles’. 13th Century In the 13th century a Celestial Globe, now housed in the Mathematisch-Physikalischer Salon in Dresden, ‘was produced at one of the most important centres of astronomy in intellectual history, the Ilkhanid observatory at Maragha in north-western Iran constructed in 1259 and headed by Nasir al-Dln TusT (d. 1274), the renowned polymath.’ This particular scientific instrument was made by the son of the renowned scientist Mu'ayyad al-’Urdi al-Dimashqi, Muhammad b. Mu'ayyad al-'Urdl in 1288. This globe is an interesting example of how Celestial Globes demonstrate both the scientific and the artistic talents of those who make them. All ‘forty-eight classical constellations used in Ptolemy's Almagest are represented on the globe, meaning it could then be ‘used in calculations for astronomy and astrology, such as navigation, time-keeping or determining a horoscope’. Artistically, this globe is an exciting insight into thirteenth century Iranian illustration as the |
attack the Baháʼí Faith. Examples include Ávárih, Sobhi and Níkú. Excluded categories of people Shoghi Effendi wrote to the National Spiritual Assembly of Canada in 1957: Beyond this, many other relationships to the Baháʼí Faith exist, both positive and negative. Covenant-breaking does not apply to most of them. The following is a partial list of those who could not rightly be termed Covenant-breakers: Members of other religions or no religion—with or without any particular relationship to the Baháʼí Faith. Baháʼís who simply leave the religion. (see above) Baháʼís who, in the estimation of the head of the religion have insufficiently understood the nature of the covenant from the start. These are sometimes "disenrolled" and are considered to have never actually been Baháʼís, given their fundamental diversion from this core Baháʼí doctrine. Bábís Bábís are generally regarded as another religion altogether. Since Covenant-breaking presumes that one has submitted oneself to a covenant and then broken it, and Bábís never recognized or swore allegiance to Baháʼu'lláh, they are not Covenant-breakers. Followers of Subh-i-Azal, Baháʼu'lláh's half-brother who tried to poison him, engaged in active opposition to Baháʼís, and Shoghi Effendi did inform Baháʼís that they should avoid contact with his descendants, writing that "No intelligent and loyal Baha'i would associate with a descendant of Azal, if he traced the slightest breath of criticism of our Faith, in any aspect, from that person. In fact these people should be strenuously avoided as having an inherited spiritual disease -- the disease of Covenant-breaking!". Shoghi Effendi's immediate family Through the influence of Bahíyyih Khánum, the eldest daughter of Baháʼu'lláh, everyone in the household initially rallied around Shoghi Effendi after the death of ʻAbdu'l-Bahá. For several years his brother Husayn and several cousins served him as secretaries. The only ones publicly opposing him were Mírzá Muhammad ʻAlí and his followers, who were declared Covenant-breakers by ʻAbdu'l-Bahá. Contrary to ʻAbdu'l-Bahá's specific instruction, certain family members established illicit links with those whom ʻAbdu'l-Bahá had declared Covenant-breakers. After Bahíyyih Khánum died in 1932, Shoghi Effendi's eldest sister – Ruhangiz – married Nayyer Effendi Afnan, a son of Siyyid Ali Afnan, son of Baháʼu'lláh though Furughiyyih. The children of Furughiyyih sided with Muhammad ʻAlí and opposed ʻAbdu'l-Bahá, leaving only ʻAbdu'l-Bahá's own children as faithful among the descendants of Baháʼu'lláh. Nayyer, in particular, was one of the greatest enemies of Shoghi Effendi throughout his time as Guardian. The marriage of Ruhangiz and Nayyer caused convulsions in the family, and it was followed by another sister of Shoghi Effendi – Mehrangiz – marrying another son of Siyyid Ali. A third son of Siyyid Ali – Faydi – also married Thurayyá, a granddaughter of ʻAbdu'l-Bahá through Túbá. These marriages caused Ruhangiz, Mehrangiz, and Thurayyá to be declared Covenant-breakers by Shoghi Effendi, though there was some delay and concealment initially in order to avoid public degradation of the family. On 2 November 1941 Shoghi Effendi sent two cables announcing the expulsion of Túbá and her children Ruhi, Suhayl, and Fu'ad for consenting to the marriage of Thurayyá to Faydi. There was also mention that Ruhi's visit to America and Fu'ad's visit to England were without approval. In December 1941 he announced the expulsion of his sister Mehrangiz. Presumably being faced with a choice between shunning their disobedient family members and being themselves disobedient to ʻAbdu'l-Bahá and Shoghi Effendi, his cousins, aunts and uncles chose the latter. Expulsions In 1944 Shoghi Effendi announced the expulsion of Munib Shahid, the grandson of ʻAbdu'l-Bahá's through Ruha, for marrying into the family of an enemy of the Baháʼís. In April 1945, he announced the expulsion of Husayn Ali, his brother, for joining the other Covenant-breakers. In a 1950 Shoghi Effendi sent another cable expelling the family of Ruha, another daughter of ʻAbdu'l-Bahá for showing "open defiance", and in December 1951 he announced a "fourth alliance" of members of the family of Siyyid Ali marrying into Ruha's family, and that his brother Riaz was included among the Covenant-breakers. In 1953 he cabled about Ruhi Afnan corresponding with Mirza Ahmad Sohrab, selling property of Baháʼu'lláh, and publicly "misrepresenting the teachings and deliberately causing confusion in minds of authorities and the local population". Resultant groups Most of the groups regarded by the larger group of Baháʼís as Covenant-breakers originated in the claims of Charles Mason Remey to the Guardianship in 1960. The Will and Testament of ʻAbdu'l-Bahá states that Guardians should be lineal descendants of Baháʼu'lláh, that each Guardian must select his successor during his lifetime, and that the nine Hands of the Cause of God permanently stationed in the holy land must approve the appointment by majority vote. Baháʼís interpret lineal descendency to mean physical familial relation to Baháʼu'lláh, of which Mason Remey was not. Almost all of Baháʼís accepted the determination of the Hands of the Cause that upon the death of Shoghi Effendi, he died "without having appointed his successor". There was an absence of a valid descendant of Baháʼu'lláh who could qualify under the terms of ʻAbdu'l-Bahá's will. Later the Universal House of Justice, initially elected in 1963, made a ruling on the subject that it | Ruhangiz – married Nayyer Effendi Afnan, a son of Siyyid Ali Afnan, son of Baháʼu'lláh though Furughiyyih. The children of Furughiyyih sided with Muhammad ʻAlí and opposed ʻAbdu'l-Bahá, leaving only ʻAbdu'l-Bahá's own children as faithful among the descendants of Baháʼu'lláh. Nayyer, in particular, was one of the greatest enemies of Shoghi Effendi throughout his time as Guardian. The marriage of Ruhangiz and Nayyer caused convulsions in the family, and it was followed by another sister of Shoghi Effendi – Mehrangiz – marrying another son of Siyyid Ali. A third son of Siyyid Ali – Faydi – also married Thurayyá, a granddaughter of ʻAbdu'l-Bahá through Túbá. These marriages caused Ruhangiz, Mehrangiz, and Thurayyá to be declared Covenant-breakers by Shoghi Effendi, though there was some delay and concealment initially in order to avoid public degradation of the family. On 2 November 1941 Shoghi Effendi sent two cables announcing the expulsion of Túbá and her children Ruhi, Suhayl, and Fu'ad for consenting to the marriage of Thurayyá to Faydi. There was also mention that Ruhi's visit to America and Fu'ad's visit to England were without approval. In December 1941 he announced the expulsion of his sister Mehrangiz. Presumably being faced with a choice between shunning their disobedient family members and being themselves disobedient to ʻAbdu'l-Bahá and Shoghi Effendi, his cousins, aunts and uncles chose the latter. Expulsions In 1944 Shoghi Effendi announced the expulsion of Munib Shahid, the grandson of ʻAbdu'l-Bahá's through Ruha, for marrying into the family of an enemy of the Baháʼís. In April 1945, he announced the expulsion of Husayn Ali, his brother, for joining the other Covenant-breakers. In a 1950 Shoghi Effendi sent another cable expelling the family of Ruha, another daughter of ʻAbdu'l-Bahá for showing "open defiance", and in December 1951 he announced a "fourth alliance" of members of the family of Siyyid Ali marrying into Ruha's family, and that his brother Riaz was included among the Covenant-breakers. In 1953 he cabled about Ruhi Afnan corresponding with Mirza Ahmad Sohrab, selling property of Baháʼu'lláh, and publicly "misrepresenting the teachings and deliberately causing confusion in minds of authorities and the local population". Resultant groups Most of the groups regarded by the larger group of Baháʼís as Covenant-breakers originated in the claims of Charles Mason Remey to the Guardianship in 1960.

There was an absence of a valid descendant of Baháʼu'lláh who could qualify under the terms of ʻAbdu'l-Bahá's will. Later the Universal House of Justice, initially elected in 1963, made a ruling on the subject that it was not possible for another Guardian to be appointed. In 1960 Remey, a Hand of the Cause himself, retracted his earlier position, and claimed to have been coerced. He claimed to be the successor to Shoghi Effendi. He and the small number of people who followed him were expelled from the mainstream Baháʼí community by the Hands of the Cause. Those close to Remey claimed that he went senile in old age, and by the time of his death he was largely abandoned, with his most prominent followers fighting amongst themselves for leadership. The largest group of the remaining followers of Remey, members of the "Orthodox Baháʼí Faith", believe that legitimate authority passed from Shoghi Effendi to Mason Remey to Joel Marangella. They, therefore, regard the Universal House of Justice in Haifa, Israel to be illegitimate, and its members and followers to be Covenant-breakers. In 2009, Jeffery Goldberg and Janice Franco, both from the mainstream Baháʼí community, joined the Orthodox Baháʼí Faith. Both of them were declared as Covenant-breakers and shunned. Goldberg's wife was told to divorce her husband. The present descendants of expelled members of Baháʼu'lláh's family have not specifically been declared Covenant-breakers, though they mostly do not associate themselves with the Baháʼí religion. A small group of Baháʼís in Northern New Mexico believe that these descendants are eligible for appointment to the Guardianship and are waiting for such a direct descendant of Baháʼu'lláh to arise as the rightful Guardian. Enayatullah (Zabih) Yazdani was designated a Covenant-breaker in June 2005, after many years of insisting on his views that Mason Remey was the legitimate successor to Shoghi Effendi and of accepting Donald Harvey as the third guardian. He is now the fifth guardian of a small group of Baháʼís and resides in Australia. There is also a small group in Montana, originally inspired by Leland Jensen, who claimed a status higher than that of the Guardian. His failed apocalyptic predictions and unsuccessful efforts to reestablish the Guardianship and the administration were apparent by his death in 1996. A dispute among Jensen's followers over the identity of the Guardian resulted in another division in 2001. American opposition Juan Cole, an American professor of Middle Eastern history who had been a Baháʼí for 25 years, left the religion in 1996 after being approached by a Continental Counselor about his involvement in a secret email list that was organizing opposition to certain Baháʼí institutions and policies. Cole was never labeled a Covenant-breaker, because he claimed to be Universalist-Unitarian upon leaving. He went on to publish three papers in journals in 1998, 2000, and 2002. These heavily criticized the Baháʼí administration in the United States and suggested cult-like tendencies, particularly regarding the requirement of pre-publication literature review and the practice of shunning Covenant-breakers. For example, Cole wrote in 1998, "Baha’is, like members of the Watchtower and other cults, shun those who are excommunicated." In 2000, "Baha'i authorities... keep believers in line by appealing to the welfare and unity |

the incident, the system provider had failed to react to proof of the security flaw provided by the CCC, claiming to the public that their system was safe. Bildschirmtext was the biggest commercially available online system targeted at the general public in its region at that time, run and heavily advertised by the German telecommunications agency Deutsche Bundespost which also strove to keep up-to-date alternatives out of the market. Karl Koch In 1987, the CCC was peripherally involved in the first cyberespionage case to make international headlines. A group of German hackers led by Karl Koch, who was loosely affiliated with the CCC, was arrested for breaking into US government and corporate computers, and then selling operating-system source code to the Soviet KGB. This incident was portrayed in the movie 23. GSM-Hack In April 1998, the CCC successfully demonstrated the cloning of a GSM customer card, breaking the COMP128 encryption algorithm used at that time by many GSM SIMs. Project Blinkenlights In 2001, the CCC celebrated its twentieth birthday with an interactive light installation dubbed Project Blinkenlights that turned the building Haus des Lehrers in Berlin into a giant computer screen. A follow up installation, Arcade, was created in 2002 by the CCC for the Bibliothèque nationale de France. Later in October 2008 CCC's Project Blinkenlights went to Toronto, Ontario, Canada with project Stereoscope. Schäuble fingerprints In March 2008, the CCC acquired and published the fingerprints of German Minister of the Interior Wolfgang Schäuble. The magazine also included the fingerprint on a film that readers could use to fool fingerprint readers. This was done to protest the use of biometric data in German identity devices such as e-passports. Staatstrojaner affair The Staatstrojaner (Federal Trojan horse) is a computer surveillance program installed secretly on a suspect's computer, which the German police uses to wiretap Internet telephony. This "source wiretapping" is the only feasible way to wiretap in this case, since Internet telephony programs will usually encrypt the data when it leaves the computer. The Federal Constitutional Court of Germany has ruled that the police may only use such programs for telephony wiretapping, and for no other purpose, and that this restriction should be enforced through technical and legal means. On 8 October 2011, the CCC published an analysis of the Staatstrojaner software. The software was found to have the ability to remote control the target computer, to capture screenshots, and to fetch and run arbitrary extra code. The CCC says that having this functionality built in is in direct contradiction to the ruling of the constitutional court. In addition, there were a number of security problems with the implementation. The software was controllable over the Internet, but the commands were sent completely unencrypted, with no checks for authentication or integrity. This leaves any computer under surveillance using this software vulnerable to attack. The captured screenshots and audio files were encrypted, but so incompetently that the encryption was ineffective. All captured data was sent over a proxy server in the United States, which is problematic since the data is then temporarily outside the German jurisdiction. The CCC's findings were widely | and technological infrastructure as well as the use of open-source software. The CCC spreads an entrepreneurial vision refusing capitalist control. It has been characterised as "…one of the most influential digital organisations anywhere, the centre of German digital culture, hacker culture, hacktivism, and the intersection of any discussion of democratic and digital rights". Members of the CCC have demonstrated and publicized a number of important information security problems. The CCC frequently criticizes new legislation and products with weak information security which endanger citizen rights or the privacy of users. Notable members of the CCC regularly function as expert witnesses for the German constitutional court, organize lawsuits and campaigns, or otherwise influence the political process. Activities Regular events The CCC hosts the annual Chaos Communication Congress, Europe's biggest hacker gathering. When the event was held in the Hamburg congress center in 2013, it drew guests. For the 2016 installment, guests were expected, with additional viewers following the event via live streaming. Every four years, the Chaos Communication Camp is the outdoor alternative for hackers worldwide. The CCC also held, from 2009 to 2013, a yearly conference called SIGINT in Cologne which focused on the impact of digitisation on society. The SIGINT conference was discontinued in 2014. The four-day conference in Karlsruhe is with more than 1500 participants the second largest annual event. Another yearly CCC event taking place on the Easter weekend is the Easterhegg, which is more workshop oriented than the other events. The CCC often uses the c-base station located in Berlin as an event location or as function rooms. Publications, Outreach The CCC publishes the irregular magazine Datenschleuder (data slingshot) since 1984. The Berlin chapter produces a monthly radio show called which picks up various technical and political topics in a two-hour talk radio show. The program is aired on a local radio station called and on the internet. Other programs have emerged in the context of Chaosradio, including radio programs offered by some regional Chaos Groups and the podcast spin-off CRE by Tim Pritlove. Many of the chapters of CCC participate in the volunteer project Chaos macht Schule which supports teaching in local schools. Its aims are to improve technology and media literacy of pupils, parents, and teachers. CCC members are present in big tech companies and in administrative instances. One of the spokespersons of the CCC, as of 1986, Andy Müller-Maguhn, was a member of the executive committee of the ICANN (Internet Corporation for Assigned Names and Numbers) between 2000 and 2002. CryptoParty The CCC sensitises and introduces people to the questions of data privacy. Some of its local chapters support or organize so called CryptoParties to introduce people to the basics of practical cryptography and internet anonymity. History Founding The CCC was founded in West Berlin on 12 September 1981 at a table which had previously belonged to the Kommune 1 in the rooms of the newspaper Die Tageszeitung by Wau Holland and others in anticipation of the prominent role that information technology would play in the way people live and communicate. BTX-Hack The CCC became world-famous in 1984 when they drew public attention to the security flaws of the German Bildschirmtext computer network by causing it to debit DM in a Hamburg bank in favor of the club. The money was returned the next day in front of the press. Prior to the incident, the system provider had failed to react to proof of the security flaw provided by the CCC, claiming to the public that their system was safe. Bildschirmtext was the biggest commercially available online system targeted at the general public in its region at that time, run and heavily advertised by the German telecommunications agency Deutsche Bundespost which also strove to keep up-to-date alternatives out of the market.

Japan, Nepal, India and the United Kingdom motorists drive on the left. The standardization of time is a human convention based on the solar cycle or calendar. The extent to which justice is conventional (as opposed to natural or objective) is historically an important debate among philosophers. The nature of conventions has raised long-lasting philosophical discussion. Quine, Davidson, and David Lewis published influential writings on the subject. Lewis's account of convention received an extended critique in Margaret Gilbert's On Social Facts (1989), where an alternative account is offered. Another view of convention comes from Ruth Millikan's Language: A Biological Model (2005), once more against Lewis. According to David Kalupahana, The Buddha described conventions—whether linguistic, social, political, moral, ethical, or even religious—as arising dependent on specific conditions. According to his paradigm, when conventions are considered absolute realities, they contribute to dogmatism, which in turn leads to conflict. This does not mean that conventions should be absolutely ignored as unreal and therefore useless. Instead, according to Buddhist thought, a wise person adopts a middle way without holding conventions to be ultimate or ignoring them when they are fruitful. Customary or social conventions Social In sociology a social rule refers to any social convention commonly adhered to in a society. These rules are not written in law or otherwise formalized. In social constructionism there is a great focus on social rules. It is argued that these rules are socially constructed, that these rules act upon every member of a society, but at the same time, are re-produced by the individuals. Sociologists representing symbolic interactionism argue that social rules are created through the interaction between the members of a society. The focus on active interaction highlights the fluid, shifting character of social rules. These are specific to the social context, a context that varies through time and place. That means a social rule changes over time within the same society. What was acceptable in the past may no longer be the case. Similarly, rules differ across space: what is acceptable in one society may not be so in another. Social rules reflect what is acceptable or normal behaviour in any situation. Michel Foucault's concept of discourse is closely related to social rules as it offers a possible explanation how these rules are shaped and change. It is the social rules that tell people what is normal behaviour for any specific category. Thus, social rules tell a woman how to behave in a womanly manner, and a man, how to be manly. Other such rules are as follows: Strangers being introduced shake hands, as in Western societies, but Bow toward each other, in Korea, Japan and China Wai each other in Thailand Do not bow at each other, in the Jewish tradition In the United States, eye contact, a nod of the head toward each other, and a smile, with no bowing; the palm of the hand faces sideways, neither upward nor downward, in a business handshake. Present business cards to each other, in business meetings (both-handed in Japan) Click heels together, while saluting in some military contexts In most places its always polite to ask before kissing or hugging, this is called public display of affection. A property norm is to place things back where we found them. A property norm is used to identify which commodities are accepted as money. A sexual norm can refer to a personal or a social norm. Most cultures have social norms regarding sexuality, and define normal sexuality to consist only of certain sex acts between individuals who meet specific criteria of age, consanguinity, race/ethnicity, and/or social role and socioeconomic status. In the west outside the traditional norm between consenting adults what is considered not normal is what falls under what is regarded as paraphilia or sexual perversion. A form of marriage, polygyny or polyandry, is right or wrong in a given society, as is homosexual marriage considered wrong in many of the societies. An religious more for an example is that a woman or man must not cohabitate, live together, when romantically involved until they have gotten married. Adultery is considered wrong that is not violating sexual fidelity when there is union of a couple in marriage. A men's and women's dress code. Avoid using rude hand gestures like pointing at people, swear words, offensive language etc., A woman's curtsey in some societies In the Middle East, never displaying the sole of the foot toward another, as this would be seen as a grave insult. In many schools, though seats for students are not assigned they are still "claimed" by certain students, and sitting in someone else's seat is considered an insult. To reciprocate when something is done for us. Etiquette norms, like asking to be excused from the gathering's table, be ready to pay for your bill particularly in the case you asked people to dinner, its a faux pas to refuse an offer of food as a guest.

His announcer was Bob Shields, who later played the judge on The Judge. Criswell wore heavy makeup in public after his live program was broadcast in Los Angeles. Only selected people were allowed in the KCOP studio during his broadcast. Criswell wrote several books of predictions, including 1968's Criswell Predicts: From Now to the Year 2000. In it, he claimed that Denver, Colorado would be struck by a ray from space that would cause all metal to adopt the qualities of rubber, leading to horrific accidents at amusement parks. He predicted mass cannibalism and the end of planet Earth, which he set as happening on August 18, 1999. Criswell was a student of history. He believed history repeated itself, that the United States were the "modern Romans". Each day, he read the St. Louis Post-Dispatch looking for clues for his predictions. Some sources claim Criswell's most famous prediction was on The Jack Paar Program (1962–65) in March 1963, when he predicted that US President John F. Kennedy would not run for reelection in 1964 because something was going to happen to him in November 1963. Sources | looking for clues for his predictions. Some sources claim Criswell's most famous prediction was on The Jack Paar Program (1962–65) in March 1963, when he predicted that US President John F. Kennedy would not run for reelection in 1964 because something was going to happen to him in November 1963. Sources say that Criswell never claimed to be a real psychic; however, those who knew him, including actress and fellow Plan 9 alumna Maila Nurmi ("Vampira"), believed he was. According to writer Charles A. Coulombe, whose family rented an apartment from him, Criswell told Coulombe's father "[I] had the gift, but ... lost it when I started taking money for it." Private life Criswell married a former speakeasy dancer named Halo Meadows, who once appeared on You Bet Your Life, and whom Coulombe describes as "quite mad": "Mrs Criswell had a huge standard poodle (named "Buttercup") which she was convinced was the reincarnation of her cousin Thomas. She spent a great deal of time sunbathing ... which, given her size, was not too pleasing a sight." Mae West used Criswell as her personal psychic; he once predicted her rise to President of the United States, whereupon she, Criswell and George Liberace, the brother of showman Liberace, would take a rocket to the Moon. Criswell and West were great friends and she would lavish him with home-cooked food which she had delivered to the studio that he shared with Maila Nurmi ("Vampira"). It is said that West sold Criswell her old luxury cars for five dollars. He died in 1982 aged 75. Legacy In 1955, Mae West wrote and recorded a song called "Criswell Predicts" for her album The Fabulous Mae West In 1994, Criswell was portrayed in the Tim Burton biopic Ed Wood by actor Jeffrey Jones. In 1997, several actors, including Sean Phillip Mabrey, have played Criswell in Plan 9 from Outer Space: The Musical, written by David G. Smith. In 1999, the film Devil Girls featured a portrayal of Criswell by Rob Gorden. In 2000, the song "Criswell Predicts" by pop punk band Groovie Ghoulies appeared on their album Travels With My Amp. In 2005, Criswell and the Plan 9 cast were lampooned in an episode of the television series, Deadly Cinema, and clips of this episode were featured in the documentary, Vampira: The Movie. In 2006, Craig Brown played Criswell in Plan Live From Outer Space, a stage adaptation of Plan 9 from Outer Space which won a Canadian Comedy Award the following year. In 2009, a teaser trailer was released by Darkstone Entertainment for the John Johnson film Plan 9, a remake of Plan 9 From Outer Space. The voice of popular television horror host Mr. Lobo can be heard narrating the trailer as Criswell. He also portrayed Criswell in the film, in a much larger role in this re-imagining of the original Ed Wood story. In addition, for the purpose of promoting the film on the internet, Mr. Lobo has produced 62 episodes of Criswell Predicts! which is a parody and homage to Criswell's original television program of the same name sans the exclamation mark.

effect"). This is a result of stored gravitational potential energy seeking a path of release over friction. Chemically, the equivalent to a snow avalanche is a spark causing a forest fire. In nuclear physics, a single stray neutron can result in a prompt critical event, which may finally be energetic enough for a nuclear reactor meltdown or (in a bomb) a nuclear explosion. Numerous chain reactions can be represented by a mathematical model based on Markov chains. Chemical chain reactions History In 1913, the German chemist Max Bodenstein first put forth the idea of chemical chain reactions. If two molecules react, not only molecules of the final reaction products are formed, but also some unstable molecules which can further react with the parent molecules with a far larger probability than the initial reactants. (In the new reaction, further unstable molecules are formed besides the stable products, and so on.) In 1918, Walther Nernst proposed that the photochemical reaction between hydrogen and chlorine is a chain reaction in order to explain what's known as the quantum yield phenomena. This means that one photon of light is responsible for the formation of as many as 106 molecules of the product HCl. Nernst suggested that the photon dissociates a Cl2 molecule into two Cl atoms which each initiate a long chain of reaction steps forming HCl. In 1923, Danish and Dutch scientists Christian Christiansen and Hendrik Anthony Kramers, in an analysis of the formation of polymers, pointed out that such a chain reaction need not start with a molecule excited by light, but could also start with two molecules colliding violently due to thermal energy as previously proposed for initiation of chemical reactions by van' t Hoff. Christiansen and Kramers also noted that if, in one link of the reaction chain, two or more unstable molecules are produced, the reaction chain would branch and grow. The result is in fact an exponential growth, thus giving rise to explosive increases in reaction rates, and indeed to chemical explosions themselves. This was the first proposal for the mechanism of chemical explosions. A quantitative chain chemical reaction theory was created later on by Soviet physicist Nikolay Semyonov in 1934. Semyonov shared the Nobel Prize in 1956 with Sir Cyril Norman Hinshelwood, who independently developed many of the same quantitative concepts. Typical steps The main types of steps in chain reaction are of the following types. Initiation (formation of active particles or chain carriers, often free radicals, in either a thermal or a photochemical step) Propagation (may comprise several elementary steps in a cycle, where the active particle through reaction forms another active particle which continues the reaction chain by entering the next elementary step). In effect the active particle serves as a catalyst for the overall reaction of the propagation cycle. Particular cases are: * chain branching (a propagation step where one active particle enters the step and two or more are formed); * chain transfer (a propagation step in which the active particle is a growing polymer chain which reacts to form an inactive polymer whose growth is terminated and an active small particle (such as a radical), which may then react to form a new polymer chain). Termination (elementary step in which the active particle loses its activity; e. g. by recombination of two free radicals). The chain length is defined as the average number of times the propagation cycle is repeated, and equals the overall reaction rate divided by the initiation rate. Some chain reactions have complex rate equations with fractional order or mixed order kinetics. Detailed example: the hydrogen-bromine reaction The reaction H2 + Br2 → 2 HBr proceeds by the following mechanism: Initiation Br2 → 2 Br• (thermal) or Br2 + hν → 2 Br• (photochemical) each Br atom is a free radical, indicated by the symbol « • » representing an unpaired electron. Propagation (here a cycle of two steps) Br• + H2 → HBr + H• H• + Br2 → HBr + Br• the sum of these two steps corresponds to the overall reaction H2 + Br2 → 2 HBr, with catalysis by Br• which participates in the first step and is regenerated in the second step. Retardation (inhibition) H• + HBr → H2 + Br• this step is specific to this example, and corresponds to the first propagation step in reverse. Termination 2 Br• → Br2 recombination of two radicals, corresponding in this example to initiation in reverse. As can be explained using the steady-state approximation, the thermal reaction has an initial rate of fractional order (3/2), and a complete rate equation with a two-term | the active particle loses its activity; e. g. by recombination of two free radicals).

As can be explained using the steady-state approximation, the thermal reaction has an initial rate of fractional order (3/2), and a complete rate equation with a two-term denominator (mixed-order kinetics). Further chemical examples The reaction 2 H2 + O2 → 2 H2O provides an example of chain branching. The propagation is a sequence of two steps whose net effect is to replace an H atom by another H atom plus two OH radicals. This leads to an explosion under certain conditions of temperature and pressure. H + O2 → OH + O O + H2 → OH + H In chain-growth polymerization, the propagation step corresponds to the elongation of the growing polymer chain. Chain transfer corresponds to transfer of the activity from this growing chain, whose growth is terminated, to another molecule which may be a second growing polymer chain. For polymerization, the kinetic chain length defined above may differ from the degree of polymerization of the product macromolecule. Polymerase chain reaction, a technique used in molecular biology to amplify (make many copies of) a piece of DNA by in vitro enzymatic replication using a DNA polymerase. Acetaldehyde pyrolysis and rate equation The pyrolysis (thermal decomposition) of acetaldehyde, CH3CHO (g) → CH4 (g) + CO (g), proceeds via the Rice-Herzfeld mechanism: Initiation (formation of free radicals): CH3CHO (g) → •CH3 (g) + •CHO (g) k1 The methyl and CHO groups are free radicals. Propagation (two steps): •CH3 (g) + CH3CHO (g) → CH4 (g) + •CH3CO (g) k2 This reaction step provides methane, which is one of the two main products. •CH3CO (g) → CO (g) + •CH3 (g) k3 The product •CH3CO (g) of the previous step gives rise to carbon monoxide (CO), which is the second main product. The sum of the two propagation steps corresponds to the overall reaction CH3CHO (g) → CH4 (g) + CO (g), catalyzed by a methyl radical •CH3. Termination: •CH3 (g) + •CH3 (g) → C2H6 (g) k4 This reaction is the only source of ethane (minor product) and it is concluded to be the main chain ending step. Although this mechanism explains the principal products, there are others that are formed in a minor degree, such as acetone (CH3COCH3) and propanal (CH3CH2CHO). Applying the Steady State Approximation for the intermediate species CH3(g) and CH3CO(g), the rate law for the formation of methane and the order of reaction are found: The rate of formation of the product methane is For the intermediates and Adding (2) and (3), we obtain so that Using (4) in (1) gives the rate law , which is order 3/2 in the reactant CH3CHO. Nuclear chain reactions A nuclear chain reaction was proposed by Leo Szilard in 1933, shortly after the neutron was discovered, yet more than five years |
Many states at this time particularly in the South legally required golf clubs to provide separate washrooms, etc. for blacks and whites. Such clubs would have never allowed caddies access to members-only facilities in any case. Moreover, the "Jim Crow morality" of the era demanded that whites (particularly in the upper classes) ensure that blacks have ample opportunity to perform menial work to ensure they contributed to society, thus attempting to restrict caddying to whites would have been socially unacceptable to the Southern white elites of the time. Types of caddying Traditional caddying involves both the golfer and the caddie walking the course. The caddie is in charge of carrying the player's bag, keeping the clubs clean, and washing the ball when on the green, and walks ahead of the golfer to locate their ball and calculate the yardage to the pin and/or hazards. Sometimes, a caddy is asked for opinions on matters such as club selection, what/where to hit and/or where to aim a putt. This is the most common method used in golf clubs and is the only method allowed in the PGA (Professional Golf Association) and LPGA (Ladies Professional Golf Association). The three usual "ups" of caddying are: show up, shut up, and keep up. Fore-Caddying entails the caddie walking while the players ride in carts. The fore-caddie will give a hole description and then walk ahead to spot the players' tee shots. The caddie then gets the player's yardage (either with a GPS watch, laser, course knowledge, or sprinkler heads) while the players drive their carts from the tee to their shots. The caddie walks ahead again to spot the golfer's next shots. This process is continued until the players reach the green. Once on the green the caddie will read greens (if asked per proper golf etiquette), clean golf balls (if asked), fix ball marks, and attend the flag. The usual rule is that the first golfer on the green's caddy tends the flag. The caddie is also responsible for raking traps on the course. Caddies may be asked to help with club selection, reading greens, weather variables, and marking balls on the green. More than anything else, the caddie is there to make the player's round enjoyable by taking care of menial tasks, speeding up play, and providing mental support if asked. Caddie ranks Many clubs use a ranking system. Caddies will start as a trainee, and be promoted through the ranks of Intermediate, Captain, Honor, and finally Championship. Many courses start their caddies off at the B level, and after a year move them to A, and on their fourth year (if they have earned it), they will receive the title of Honor caddie. The intermediate and captain ranks can usually be obtained within the first year of caddying, and the honor rank is usually obtained in the second or third year of caddying. Championship takes at least 6 years and often as many as 10 years to obtain. An alternative ranking system often used in the American Mid-West proceeds as B level, A level, AA level, Honor level, and Evans Scholar. Caddies often obtain a promotion in rank once a year, while often Honor takes two years to achieve and Evans Scholars are only produced by winning the venerable Evans Scholarship for university. However, in many American clubs, caddies are divided simply between "B" caddies (usually younger, less experienced caddies who often carry only one bag), and "A" caddies (usually older, more experienced caddies). Day of a caddy Caddies report early each morning at the "Caddy Shack" where they wait until the caddie master assigns them to a golfer. At that time, they retrieve the golfer's bag (typically from the bag room) and wait to meet the golfer out in an open area. When done with the morning round of golf (a loop), the caddie can either wait to work an afternoon "loop" or leave for the day. Caddies can also begin work later in the morning to work only afternoons based on how busy they anticipate the club to be. Weekly schedule Caddies typically work at clubs all week except Mondays with most traffic on weekends, being the busiest days. Additionally, caddies are often allowed to play the course at which they caddie for free, usually on a Monday (the day that most private clubs choose to close their course for maintenance).

Additionally, the player may hire their caddie to carry their bag for them during training sessions and practice rounds. Pay scale At most clubs, caddies are paid at the end of the round by cash, or receive a payment ticket for which they can redeem their wages in the clubhouse. Generally, the player will tip the caddie based on their performance during the round, with extra money given for exemplary work or for working special event such as a tournament.

Tandem compound or cross compound The rotor arrangement can be either tandem-compound in which the two axles are joined end to end, or cross-compound in which the two turbines have separate axles. In the cross-compound case two separate generators are usually supplied, although a gearbox can reduce this to one. Advantages The principal advantages of compound turbines are the reduction in size of any one | principal advantages of compound turbines are the reduction in size of any one casing, the confinement of the highest pressure to the smaller casing (which may be made of stronger and more expensive materials) and the possibility of divided flow in the low-pressure casing for the purpose of equalizing end thrusts.

can vary considerably: from seconds to several months. The typical sizes of the regions where coronal events take place vary in the same way, as it is shown in the following table. Flares Flares take place in active regions and are characterized by a sudden increase of the radiative flux emitted from small regions of the corona. They are very complex phenomena, visible at different wavelengths; they involve several zones of the solar atmosphere and many physical effects, thermal and not thermal, and sometimes wide reconnections of the magnetic field lines with material expulsion. Flares are impulsive phenomena, of average duration of 15 minutes, and the most energetic events can last several hours. Flares produce a high and rapid increase of the density and temperature. An emission in white light is only seldom observed: usually, flares are only seen at extreme UV wavelengths and into the X-rays, typical of the chromospheric and coronal emission. In the corona, the morphology of flares is described by observations in the UV, soft and hard X-rays, and in Hα wavelengths, and is very complex. However, two kinds of basic structures can be distinguished: Compact flares, when each of the two arches where the event is happening maintains its morphology: only an increase of the emission is observed without significant structural variations. The emitted energy is of the order of 1022 – 1023 J. Flares of long duration, associated with eruptions of prominences, transients in white light and two-ribbon flares: in this case the magnetic loops change their configuration during the event. The energies emitted during these flares are of such great proportion they can reach 1025 J. As for temporal dynamics, three different phases are generally distinguished, whose duration are not comparable. The durations of those periods depend on the range of wavelengths used to observe the event: An initial impulsive phase, whose duration is on the order of minutes, strong emissions of energy are often observed even in the microwaves, EUV wavelengths and in the hard X-ray frequencies. A maximum phase A decay phase, which can last several hours. Sometimes also a phase preceding the flare can be observed, usually called as "pre-flare" phase. Coronal mass ejections Often accompanying large solar flares and prominences are coronal mass ejections (CME). These are enormous emissions of coronal material and magnetic field that travel outward from the Sun at over a million kilometers per hour, containing roughly 10 times the energy of the solar flare or prominence that accompanies them. Some larger CMEs can propel hundreds of millions of tons of material into interplanetary space at roughly 1.5 million kilometers an hour. Stellar coronae Coronal stars are ubiquitous among the stars in the cool half of the Hertzsprung–Russell diagram. These coronae can be detected using X-ray telescopes. Some stellar coronae, particularly in young stars, are much more luminous than the Sun's. For example, FK Comae Berenices is the prototype for the FK Com class of variable star. These are giants of spectral types G and K with an unusually rapid rotation and signs of extreme activity. Their X-ray coronae are among the most luminous (Lx ≥ 1032 erg·s−1 or 1025W) and the hottest known with dominant temperatures up to 40 MK. The astronomical observations planned with the Einstein Observatory by Giuseppe Vaiana and his group showed that F-, G-, K- and M-stars have chromospheres and often coronae much like our Sun. The O-B stars, which do not have surface convection zones, have a strong X-ray emission. However these stars do not have coronae, but the outer stellar envelopes emit this radiation during shocks due to thermal instabilities in rapidly moving gas blobs. Also A-stars do not have convection zones but they do not emit at the UV and X-ray wavelengths. Thus they appear to have neither chromospheres nor coronae. Physics of the corona The matter in the external part of the solar atmosphere is in the state of plasma, at very high temperature (a few million kelvin) and at very low density (of the order of 1015 particles/m3). According to the definition of plasma, it is a quasi-neutral ensemble of particles which exhibits a collective behaviour. The composition is similar to that in the Sun's interior, mainly hydrogen, but with much greater ionization than that found in the photosphere. Heavier metals, such as iron, are partially ionized and have lost most of the external electrons. The ionization state of a chemical element depends strictly on the temperature and is regulated by the Saha equation in the lowest atmosphere, but by collisional equilibrium in the optically-thin corona. Historically, the presence of the spectral lines emitted from highly ionized states of iron allowed determination of the high temperature of the coronal plasma, revealing that the corona is much hotter than the internal layers of the chromosphere. The corona behaves like a gas which is very hot but very light at the same time: the pressure in the corona is usually only 0.1 to 0.6 Pa in active regions, while on the Earth the atmospheric pressure is about 100 kPa, approximately a million times higher than on the solar surface. However it is not properly a gas, because it is made of charged particles, basically protons and electrons, moving at different velocities. Supposing that they have the same kinetic energy on average (for the equipartition theorem), electrons have a mass roughly times smaller than protons, therefore they acquire more velocity. Metal ions are always slower. This fact has relevant physical consequences either on radiative processes (that are very different from the photospheric radiative processes), or on thermal conduction. Furthermore, the presence of electric charges induces the generation of electric currents and high magnetic fields. Magnetohydrodynamic waves (MHD waves) can also propagate in this plasma, even though it is still not clear how they can be transmitted or generated in the corona. Radiation Coronal plasma is optically-thin and therefore transparent to the electromagnetic radiation that it emits and to that coming from lower layers. The plasma is very rarefied and the photon mean free path overcomes by far all the other length-scales, including the typical sizes of common coronal features. Electromagnetic radiation from the corona has been identified coming from three main sources, located in the same volume of space: The K-corona (K for kontinuierlich, "continuous" in German) is created by sunlight Thomson scattering off free electrons; doppler broadening of the reflected photospheric absorption lines spreads them so greatly as to completely obscure them, giving the spectral appearance of a continuum with no absorption lines. The F-corona (F for Fraunhofer) is created by sunlight bouncing off dust particles, and is observable because its light contains the Fraunhofer absorption lines that are seen in raw sunlight; the F-corona extends to very high elongation angles from the Sun, where it is called the zodiacal light. The E-corona (E for emission) is due to spectral emission lines produced by ions that are present in the coronal plasma; it may be observed in broad or forbidden or hot spectral emission lines and is the main source of information about the corona's composition. Thermal conduction In the corona thermal conduction occurs from the external hotter atmosphere towards the inner cooler layers. Responsible for the diffusion process of the heat are the electrons, which are much lighter than ions and move faster, as explained above. When there is a magnetic field the thermal conductivity of the plasma becomes higher in the direction which is parallel to the field lines rather than in the perpendicular direction. A charged particle moving in the direction perpendicular to the magnetic field line is subject to the Lorentz force which is normal to the plane individuated by the velocity and the magnetic field. This force bends the path of the particle. In general, since particles also have a velocity component along the magnetic field line, the Lorentz force constrains them to bend and move along spirals around the field lines at the cyclotron frequency. If collisions between the particles are very frequent, they are scattered in every direction. This happens in the photosphere, where the plasma carries the magnetic field in its motion. In the corona, on the contrary, the mean free-path of the electrons is of the order of kilometres and even more, so each electron can do a helicoidal motion long before being scattered after a collision. Therefore, the heat transfer is enhanced along the magnetic field lines and inhibited in the perpendicular direction. In the direction longitudinal to the magnetic field, the thermal conductivity of the corona is where is the Boltzmann constant, is the temperature in kelvin, is the electron mass, is the electric charge of the electron, is the Coulomb logarithm, and is the Debye length of the plasma with particle density . The Coulomb logarithm is roughly 20 in the corona, with a mean temperature of 1 MK and a density of 1015 particles/m3, and about 10 in the chromosphere, where the temperature is approximately 10kK and the particle density is of the order of 1018 particles/m3, and in practice it can be assumed constant. Thence, if we indicate with the heat for a volume unit, expressed in J m−3, the Fourier equation of heat transfer, to be computed only along the direction of the field line, becomes . Numerical calculations have shown that the thermal conductivity of the corona is comparable to that of copper. Coronal seismology Coronal seismology is a method of studying the plasma of the solar corona with the use of magnetohydrodynamic (MHD) waves. MHD studies the dynamics of electrically conducting fluids—in this case the fluid is the coronal plasma. Philosophically, coronal seismology is similar to the Earth's seismology, the Sun's helioseismology, and MHD spectroscopy of laboratory plasma devices. In all these approaches, waves of various kinds are used to probe a medium. The potential of coronal seismology in the estimation of the coronal magnetic field, density scale height, fine structure and heating has been demonstrated by different research groups. Coronal heating problem The coronal heating problem in solar physics relates to the question of why the temperature of the Sun's corona is millions of kelvins greater than that of the surface. Several theories have been proposed to explain this phenomenon but it is still challenging to determine which of these is correct. The problem first emerged when Bengt Edlen and Walter Grotrian identified Fe IX and Ca XIV | temporal dynamics, three different phases are generally distinguished, whose duration are not comparable.

The O-B stars, which do not have surface convection zones, have a strong X-ray emission. However these stars do not have coronae, but the outer stellar envelopes emit this radiation during shocks due to thermal instabilities in rapidly moving gas blobs. Also A-stars do not have convection zones but they do not emit at the UV and X-ray wavelengths. Thus they appear to have neither chromospheres nor coronae. Physics of the corona The matter in the external part of the solar atmosphere is in the state of plasma, at very high temperature (a few million kelvin) and at very low density (of the order of 1015 particles/m3). According to the definition of plasma, it is a quasi-neutral ensemble of particles which exhibits a collective behaviour. The composition is similar to that in the Sun's interior, mainly hydrogen, but with much greater ionization than that found in the photosphere. Heavier metals, such as iron, are partially ionized and have lost most of the external electrons. The ionization state of a chemical element depends strictly on the temperature and is regulated by the Saha equation in the lowest atmosphere, but by collisional equilibrium in the optically-thin corona. Historically, the presence of the spectral lines emitted from highly ionized states of iron allowed determination of the high temperature of the coronal plasma, revealing that the corona is much hotter than the internal layers of the chromosphere. The corona behaves like a gas which is very hot but very light at the same time: the pressure in the corona is usually only 0.1 to 0.6 Pa in active regions, while on the Earth the atmospheric pressure is about 100 kPa, approximately a million times higher than on the solar surface. However it is not properly a gas, because it is made of charged particles, basically protons and electrons, moving at different velocities. Supposing that they have the same kinetic energy on average (for the equipartition theorem), electrons have a mass roughly times smaller than protons, therefore they acquire more velocity. Metal ions are always slower. This fact has relevant physical consequences either on radiative processes (that are very different from the photospheric radiative processes), or on thermal conduction. Furthermore, the presence of electric charges induces the generation of electric currents and high magnetic fields. Magnetohydrodynamic waves (MHD waves) can also propagate in this plasma, even though it is still not clear how they can be transmitted or generated in the corona. Radiation Coronal plasma is optically-thin and therefore transparent to the electromagnetic radiation that it emits and to that coming from lower layers. The plasma is very rarefied and the photon mean free path overcomes by far all the other length-scales, including the typical sizes of common coronal features. Electromagnetic radiation from the corona has been identified coming from three main sources, located in the same volume of space: The K-corona (K for kontinuierlich, "continuous" in German) is created by sunlight Thomson scattering off free electrons; doppler broadening of the reflected photospheric absorption lines spreads them so greatly as to completely obscure them, giving the spectral appearance of a continuum with no absorption lines. The F-corona (F for Fraunhofer) is created by sunlight bouncing off dust particles, and is observable because its light contains the Fraunhofer absorption lines that are seen in raw sunlight; the F-corona extends to very high elongation angles from the Sun, where it is called the zodiacal light. The E-corona (E for emission) is due to spectral emission lines produced by ions that are present in the coronal plasma; it may be observed in broad or forbidden or hot spectral emission lines and is the main source of information about the corona's composition. Thermal conduction In the corona thermal conduction occurs from the external hotter atmosphere towards the inner cooler layers. Responsible for the diffusion process of the heat are the electrons, which are much lighter than ions and move faster, as explained above. When there is a magnetic field the thermal conductivity of the plasma becomes higher in the direction which is parallel to the field lines rather than in the perpendicular direction. A charged particle moving in the direction perpendicular to the magnetic field line is subject to the Lorentz force which is normal to the plane individuated by the velocity and the magnetic field. This force bends the path of the particle. In general, since particles also have a velocity component along the magnetic field line, the Lorentz force constrains them to bend and move along spirals around the field lines at the cyclotron frequency. If collisions between the particles are very frequent, they are scattered in every direction. This happens in the photosphere, where the plasma carries the magnetic field in its motion. In the corona, on the contrary, the mean free-path of the electrons is of the order of kilometres and even more, so each electron can do a helicoidal motion long before being scattered after a collision. Therefore, the heat transfer is enhanced along the magnetic field lines and inhibited in the perpendicular direction. In the direction longitudinal to the magnetic field, the thermal conductivity of the corona is where is the Boltzmann constant, is the temperature in kelvin, is the electron mass, is the electric charge of the electron, is the Coulomb logarithm, and is the Debye length of the plasma with particle density . The Coulomb logarithm is roughly 20 in the corona, with a mean temperature of 1 MK and a density of 1015 particles/m3, and about 10 in the chromosphere, where the temperature is approximately 10kK and the particle density is of the order of 1018 particles/m3, and in practice it can be assumed constant. Thence, if we indicate with the heat for a volume unit, expressed in J m−3, the Fourier equation of heat transfer, to be computed only along the direction of the field line, becomes . Numerical calculations have shown that the thermal conductivity of the corona is comparable to that of copper. Coronal seismology Coronal seismology is a method of studying the plasma of the solar corona with the use of magnetohydrodynamic (MHD) waves. MHD studies the dynamics of electrically conducting fluids—in this case the fluid is the coronal plasma. Philosophically, coronal seismology is similar to the Earth's seismology, the Sun's helioseismology, and MHD spectroscopy of laboratory plasma devices. In all these approaches, waves of various kinds are used to probe a medium. The potential of coronal seismology in the estimation of the coronal magnetic field, density scale height, fine structure and heating has been demonstrated by different research groups. Coronal heating problem The coronal heating problem in solar physics relates to the question of why the temperature of the Sun's corona is millions of kelvins greater than that of the surface. Several theories have been proposed to explain this phenomenon but it is still challenging to determine which of these is correct. The problem first emerged when Bengt Edlen and Walter Grotrian identified Fe IX and Ca XIV lines in the solar spectrum. This led to the discovery that the emission lines seen during solar eclipses are not caused by an unknown element called "coronium" but known elements at very high stages of ionization. The comparison of the coronal and the photospheric temperatures of 6,000K, leads to the question of how the 200 times hotter coronal temperature can be maintained. The problem is primarily concerned with how the energy is transported up into the corona and then converted into heat within a few solar radii. The high temperatures require energy to be carried from the solar interior to the corona by non-thermal processes, because the second law of thermodynamics prevents heat from flowing directly from the solar photosphere (surface), which is at about , to the much hotter corona at about 1 to 3 MK (parts of the corona can even reach ). Between the photosphere and the corona, the thin region through which the temperature increases is known as the transition region. It ranges from only tens to hundreds of kilometers thick. Energy cannot be transferred from the cooler photosphere to the corona by conventional heat transfer as this would violate the second law of thermodynamics. An analogy of this would be a light bulb raising the temperature of the air surrounding it to something greater than its glass surface. Hence, some other manner of energy transfer must be involved in the heating of the corona. The amount of power required to heat the solar corona can easily be calculated as the difference between coronal radiative losses and heating by thermal conduction toward the chromosphere through the transition region. It is about 1 kilowatt for every square meter of surface area on the Sun's chromosphere, or 1/ of the amount of light energy that escapes the Sun. Many coronal heating theories have been proposed, but two theories have remained as the most likely candidates: wave heating and magnetic reconnection (or nanoflares). Through most of the past 50 years, neither theory has been able to account for the extreme coronal temperatures. In 2012, high resolution (<0.2″) soft X-ray imaging with the High Resolution Coronal Imager aboard a sounding rocket revealed tightly wound braids in the corona. It is hypothesized that the reconnection and unravelling of braids can act as primary sources of heating of the active solar corona to temperatures of up to 4 million kelvin. The main heat source in the quiescent corona (about 1.5 million kelvin) is assumed to originate from MHD waves. NASA's Parker Solar Probe is intended to approach the Sun to a distance of approximately 9.5 solar radii to investigate coronal heating and the origin of the solar wind. It was successfully launched on August 12, 2018 and has completed the first few of the more than 20 planned close approaches to the Sun. Wave heating theory The wave heating theory, proposed in 1949 by Évry Schatzman, proposes that waves carry energy from the solar interior to the solar chromosphere and corona. The Sun is made of plasma rather than ordinary gas, so it supports several types of waves analogous to sound waves in air. The most important types of wave are magneto-acoustic waves and Alfvén waves. Magneto-acoustic waves are sound waves that have been modified by the presence of a magnetic field, and Alfvén waves are similar to ultra low frequency radio waves that have been modified by interaction with matter in the plasma. Both types of waves can be launched by the turbulence of granulation and super granulation at the solar photosphere, and both types of waves can carry energy for some distance through the solar atmosphere before turning into shock waves that dissipate their energy as heat. One problem with wave heating is delivery of the heat to the appropriate place. Magneto-acoustic waves cannot carry sufficient energy upward through the chromosphere to the corona, both because of the low pressure present in the chromosphere and because they tend to be reflected back to the photosphere. Alfvén waves can carry enough energy, but do not dissipate that energy rapidly enough once they enter the corona. Waves in plasmas are notoriously difficult to understand and describe analytically, but computer simulations, carried out by Thomas Bogdan and colleagues in 2003, seem to show that Alfvén waves can transmute into other wave modes at the base of the corona, providing a pathway that can carry large amounts of energy from the photosphere through the chromosphere and transition region and finally into the corona where it dissipates it as heat. Another problem with wave heating has been the complete absence, until the late 1990s, of any direct evidence of waves propagating through the solar corona. The first direct observation of waves propagating into and through the solar corona was made in 1997 with the Solar and Heliospheric Observatory space-borne solar observatory, the first platform capable of observing the Sun in the extreme ultraviolet (EUV) for long periods of time with stable photometry. Those were magneto-acoustic waves with a frequency of about 1 millihertz (mHz, corresponding to a wave period), that carry only about 10% of the energy required to heat the corona. Many observations exist of localized wave phenomena, such as Alfvén waves launched by solar flares, but those events are transient and cannot explain the uniform coronal heat. It is not yet |
color used in the upper corner of the battle screen. If the field is purely one color, characters are able to unleash a powerful summon element at the cost of one of the player's stars. The field will also enhance the power of Elements of the colors present, while weakening Elements of the opposite colors. Characters also innately learn some special techniques ("Techs") that are unique to each character but otherwise act like Elements. Like Chrono Trigger, characters can combine certain Techs to make more powerful Double or Triple Techs. Consumable Elements may be used to restore hit points or heal status ailments during or after battle. Another innovative aspect of Chrono Cross is its stamina bar. At the beginning of a battle, each character has seven points of stamina. When a character attacks or uses an Element, stamina is decreased proportionally to the potency of the attack. Stamina slowly recovers when the character defends or when other characters perform actions in battle. Characters with stamina below one point must wait to take action. Use of an Element reduces the user's stamina bar by seven stamina points; this often means that the user's stamina gauge falls into the negative and the character must wait longer than usual to recover. With each battle, players can enhance statistics such as strength and defense. However, no system of experience points exists; after four or five upgrades, statistics remain static until players defeat a boss. This adds a star to a running count shown on the status screen, which allows for another few rounds of statistical increases. Players can equip characters with weapons, armor, helmets, and accessories for use in battle; for example, the "Power Seal" upgrades attack power. Items and equipment may be purchased or found on field maps, often in treasure chests. Unlike Elements, weapons and armor cannot merely be purchased with money; instead, the player must obtain base materials—such as copper, bronze, or bone—for a blacksmith to forge for a fee. The items can later be disassembled into their original components at no cost. Parallel dimensions The existence of two major parallel dimensions, like time periods in Chrono Trigger, plays a significant role in the game. Players must go back and forth between the worlds to recruit party members, obtain items, and advance the plot. Much of the population of either world have counterparts in the other; some party members can even visit their other versions. The player must often search for items or places found exclusively in one world. Events in one dimension sometimes have an impact in the other—for instance, cooling scorched ground on an island in one world allows vegetation to grow in the other world. This system assists the presentation of certain themes, including the questioning of the importance of one's past decisions and humanity's role in destroying the environment. Rounding out the notable facets of Chrono Cross's gameplay are the New Game+ option and multiple endings. As in Chrono Trigger, players who have completed the game may choose to start the game over using data from the previous session. Character levels, learned techniques, equipment, and items gathered copy over, while acquired money and some story-related items are discarded. On a New Game+, players can access twelve endings. Scenes viewed depend on players' progress in the game before the final battle, which can be fought at any time in a New Game+ file. Plot Characters Chrono Cross features a diverse cast of 45 party members. Each character is outfitted with an innate Element affinity and three unique special abilities that are learned over time. If taken to the world opposite their own, characters react to their counterparts (if available). Many characters tie in to crucial plot events. Since it is impossible to obtain all 45 characters in one playthrough, players must replay the game to witness everything. Through use of the New Game+ feature, players can ultimately obtain all characters on one save file. Serge, the game's protagonist, is a 17-year-old boy with blue hair who lives in the fishing village of Arni. One day, he slips into an alternate world in which he drowned ten years before. Determined to find the truth behind the incident, he follows a predestined course that leads him to save the world. He is assisted by Kid, a feisty, skilled thief who seeks the mythical Frozen Flame. Portrayed as willful and tomboyish due to her rough, thieving past, she helps Serge sneak into Viper Manor in order to obtain the Frozen Flame. Kid vows to find and defeat Lynx, an anthropomorphic panther who burned down her adopted mother's orphanage. Lynx, a cruel agent of the supercomputer FATE, is bent on finding Serge and using his body as part of a greater plan involving the Frozen Flame. Lynx travels with Harle, a mysterious, playful girl dressed like a harlequin. Harle was sent by the Dragon God to shadow Lynx and one day steal the Frozen Flame from Chronopolis, a task she painfully fulfills despite being smitten with Serge. To accomplish this goal, Harle helps Lynx manipulate the Acacia Dragoons, the powerful militia governing the islands of El Nido. As the Dragoons maintain order, they contend with Fargo, a former Dragoon turned pirate captain who holds a grudge against their leader, General Viper. Though tussling with Serge initially, the Acacia Dragoons—whose ranks include the fierce warriors Karsh, Zoah, Marcy, and Glenn—later assist him when the militaristic nation of Porre invades the archipelago. The invasion brings Norris and Grobyc to the islands, a heartful commander of an elite force and a prototype cyborg soldier, respectively, as they too seek the Frozen Flame. Story The game begins with Serge located in El Nido, a tropical archipelago inhabited by ancient natives, mainland colonists, and beings called Demi-humans. Serge slips into an alternate dimension in which he drowned on the beach ten years prior, and meets the thief, "Kid". As his adventure proceeds from here, Serge is able to recruit a multitude of allies to his cause. While assisting Kid in a heist at Viper Manor to steal the Frozen Flame, he learns that ten years before the present, the universe split into two dimensions—one in which Serge lived, and one in which he perished. Through Kid's Astral Amulet charm, Serge travels between the dimensions. At Fort Dragonia, with the use of a Dragonian artifact called the Dragon Tear, Lynx switches bodies with Serge. Unaware of the switch, Kid confides in Lynx, who stabs her as the real Serge helplessly watches. Lynx boasts of his victory and banishes Serge to a strange realm called the Temporal Vortex. He takes Kid under his wing, brainwashing her to believe the real Serge (in Lynx's body) is her enemy. Serge escapes with help from Harle, although his new body turns him into a stranger in his own world, with all the allies he had gained up to that point abandoning him due to his new appearance. Discovering that his new body prevents him from traveling across the dimensions, he sets out to regain his former body and learn more of the universal split that occurred ten years earlier, gaining a new band of allies along the way. He travels to a forbidden lagoon known as the Dead Sea—a wasteland frozen in time, dotted with futuristic ruins. At the center, he locates a man named Miguel and presumably Home world's Frozen Flame. Charged with guarding the Dead Sea by an entity named FATE, Miguel and three visions of Crono, Marle, and Lucca from Chrono Trigger explain that Serge's existence dooms Home world's future to destruction at the hands of Lavos. To prevent Serge from obtaining the Frozen Flame, FATE destroys the Dead Sea. Able to return to Another world, Serge allies with the Acacia Dragoons against Porre and locates that dimension's Dragon Tear, allowing him to return to his human form. He then enters the Sea of Eden, Another world's physical equivalent of the Dead Sea, finding a temporal research facility from the distant future called Chronopolis. Lynx and Kid are inside; Serge defeats Lynx and the supercomputer FATE, allowing the six Dragons of El Nido to steal the Frozen Flame and retire to Terra Tower, a massive structure raised from the sea floor. Kid falls into a coma, and Harle bids the party goodbye to fly with the Dragons. Serge regroups his party and tends to Kid, who remains comatose. Continuing his adventure, he obtains and cleanses the corrupted Masamune sword from Chrono Trigger. He then uses the Dragon relics and shards of the Dragon Tears to create the mythic Element Chrono Cross. The spiritual power of the Masamune later allows him to lift Kid from her coma. At Terra Tower, the prophet of time, revealed to be Belthasar from Chrono Trigger, visits him with visions of Crono, Marle, and Lucca. Serge learns that the time research facility Chronopolis created El Nido thousands of years ago after a catastrophic experimental failure drew it to the past. The introduction of a temporally foreign object in history caused the planet to pull in a counterbalance from a different dimension. This was Dinopolis, a city of Dragonians—parallel universe descendants of Chrono Trigger's Reptites. The institutions warred and Chronopolis subjugated the Dragonians. Humans captured their chief creation—the Dragon God, an entity capable of controlling nature. Chronopolis divided this entity into six pieces and created an Elements system. FATE then terraformed an archipelago, erased the memories of most of Chronopolis's staff, and sent them to inhabit and populate its new paradise. Thousands of years later, a panther demon attacked a three-year-old Serge. His father took him to find assistance at Marbule, but Serge's boat blew off course due to a raging magnetic storm caused by Schala. Schala, the princess of the Kingdom of Zeal, had long ago accidentally fallen to a place known as the Darkness Beyond Time and began merging with Lavos, the chief antagonist of Chrono Trigger. Schala's storm nullified Chronopolis's defenses and allowed Serge to contact the Frozen Flame; approaching it healed Serge but corrupted his father, turning him into Lynx. A circuit in Chronopolis then designated Serge "Arbiter", simultaneously preventing FATE from using the Frozen Flame by extension. The Dragons were aware of this situation, creating a seventh Dragon under the storm's cover named Harle, who manipulated Lynx to steal the Frozen Flame for the Dragons. After Serge returned home, FATE sent Lynx to kill Serge, hoping that it would release the Arbiter lock. Ten years after Serge drowned, the thief Kid—presumably on Belthasar's orders—went back in time to save Serge and split the dimensions. FATE, locked out of the Frozen Flame again, knew that Serge would one day cross to Another world and prepared to apprehend him. Lynx switched bodies with Serge to dupe the biological check of Chronopolis on the Frozen Flame. Belthasar then reveals that these events were part of a plan he had orchestrated named Project Kid. Serge continues to the top of Terra Tower and defeats the Dragon God. Continuing to the beach where the split in dimensions had occurred, Serge finds apparitions of Crono, Marle, and Lucca once more. They reveal that Belthasar's plan was to empower Serge to free Schala from melding with Lavos, lest they evolve into the "Time Devourer", a creature capable of destroying spacetime. Lucca explains that Kid is Schala's clone, sent to the modern age to take part in Project Kid. Serge uses a Time Egg—given to him by Belthasar—to enter the Darkness Beyond Time and vanquish the Time Devourer, separating Schala from Lavos and restoring the dimensions to one. Thankful, Schala muses on evolution and the struggle of life and returns Serge to his home, noting that he will forget the entire adventure. She then seemingly records the experience in her diary, noting she will always be searching for Serge in this life and beyond, signing the entry as Schala "Kid" Zeal, implying that she and Kid have merged and became whole again. A wedding photo of Kid and an obscured male sits on the diary's desk. Scenes then depict a real-life Kid searching for someone in a modern city, intending to make players entertain the possibility that their own Kid is searching for them. The ambiguous ending leaves the events of the characters' lives following the game up to interpretation. Relation to Radical Dreamers Chrono Cross employs story arcs, characters, and themes from Radical Dreamers, a Satellaview side story to Chrono Trigger released in Japan. Radical Dreamers is an illustrated text adventure which was created to wrap up an unresolved plot line of Chrono Trigger. Though it borrows from Radical Dreamers in its exposition, Chrono Cross is not a remake of Radical Dreamers, but a larger effort to fulfill that game's purpose; the plots of the games are irreconcilable. To resolve continuity issues and acknowledge Radical Dreamers, the developers of Chrono Cross suggested the game happened in a parallel dimension. A notable difference between the two games is that Magus—present in Radical Dreamers as Gil—is absent from Chrono Cross. Director Masato Kato originally planned for Magus to appear in disguise as Guile, but scrapped the idea due to plot difficulties. Kato specifically felt that the game's large number of characters, as well as the difficult production schedule, did not allow him to develop the relationship between Magus and Kid. In the DS version of Chrono Trigger, Kato teases the possibility of an amnesiac Magus. Development Square began planning Chrono Cross immediately after the release of Xenogears in 1998 (which itself was originally conceived as a sequel to the SNES game). Chrono Trigger's scenario director Masato Kato had brainstormed ideas for a sequel as early as 1996, following the release of Radical Dreamers. Square's managers selected a team, appointed Hiromichi Tanaka producer, and asked Kato to direct and develop a new Chrono game in the spirit of Radical Dreamers. Kato thought Dreamers was released in a "half-finished state", and wanted to continue the story of the character Kid. Kato and Tanaka decided to produce an indirect sequel. They acknowledged that Square would soon re-release Chrono Trigger as part of Final Fantasy Chronicles, which would give players a chance to catch up on the story of Trigger before playing Cross. Kato thought that using a different setting and cast for Chrono Cross would allow players unfamiliar with Chrono | a grudge against their leader, General Viper.

They acknowledged that Square would soon re-release Chrono Trigger as part of Final Fantasy Chronicles, which would give players a chance to catch up on the story of Trigger before playing Cross. Kato thought that using a different setting and cast for Chrono Cross would allow players unfamiliar with Chrono Trigger to play Cross without becoming confused. The Chrono Cross team decided against integrating heavy use of time travel into the game, as they thought it would be "rehashing and cranking up the volume of the last game". Masato Kato cited the belief, "there's no use in making something similar to before ", and noted, "we're not so weak nor cheap as to try to make something exactly the same as Trigger ... Accordingly, Chrono Cross is not Chrono Trigger 2. It doesn't simply follow on from Trigger, but is another, different Chrono that interlaces with Trigger." Kato and Tanaka further explained their intentions after the game's release: Full production began on Chrono Cross in mid-1998. The Chrono Cross team reached 80 members at its peak, with additional personnel of 10–20 cut-scene artists and 100 quality assurance testers. The team felt pressure to live up to the work of Chrono Trigger's "Dream Team" development group, which included famous Japanese manga artist Akira Toriyama. Kato and Tanaka hired Nobuteru Yūki for character design and Yasuyuki Honne for art direction and concept art. The event team originally envisioned a short game, and planned a system by which players would befriend any person in a town for alliance in battle. Developers brainstormed traits and archetypes during the character-creation process, originally planning 64 characters with unique endings that could vary in three different ways per character. Kato described the character creation process: "Take Pierre, for example: we started off by saying we wanted a wacko fake hero like Tata from Trigger. We also said things like 'we need at least one powerful mom', 'no way we're gonna go without a twisted brat', and so on so forth." As production continued, the length of Cross increased, leading the event team to reduce the number of characters to 45 and scrap most of the alternate endings. Developers humorously named the character Pip "Tsumaru" in Japanese (which means "packed") as a pun on their attempts to pack as much content into the game as possible. To avoid the burden of writing unique, accented dialogue for several characters, team member Kiyoshi Yoshii coded a system that produces accents by modifying basic text for certain characters. Art director Nobuteru Yuuki initially wanted the characters to appear in a more chibi format with diminutive proportions. The game world's fusion of high technology and ethnic, tribal atmospheres proved challenging at first. He later recalled striving to harmonize the time period's level of technology, especially as reflected in characters' garb. The Chrono Cross team devised an original battle system using a stamina bar and Elements. Kato planned the system around allowing players to avoid repetitive gameplay (also known as "grinding") to gain combat experience. Hiromichi Tanaka likened the Elements system to card games, hoping players would feel a sense of complete control in battle. The team programmed each battle motion manually instead of performing motion capture. Developers strove to include tongue-in-cheek humor in the battle system's techniques and animations to distance the game from the Final Fantasy franchise. Masato Kato planned for the game's setting to feature a small archipelago, for fear that players would become confused traveling in large areas with respect to parallel worlds. He hoped El Nido would still impart a sense of grand scale, and the development team pushed hardware limitations in creating the game's world. To create field maps, the team modeled locations in 3D, then chose the best angle for 2D rendering. The programmers of Chrono Cross did not use any existing Square programs or routines to code the game, instead writing new, proprietary systems. Other innovations included variable-frame rate code for fast-forward and slow-motion gameplay (awarded as a bonus for completing the game) and a "CD-read swap" system to allow quick data retrieval. Masato Kato directed and wrote the main story, leaving sub-plots and minor character events to other staff. The event team sometimes struggled to mesh their work on the plot due to the complexity of the parallel worlds concept. Masato Kato confirmed that Cross featured a central theme of parallel worlds, as well as the fate of Schala, which he was previously unable to expound upon in Chrono Trigger. Concerning the ending sequences showing Kid searching for someone in a modern city, he hoped to make players realize that alternate futures and possibilities may exist in their own lives, and that this realization would "not ... stop with the game". He later added, "Paraphrasing one novelist's favorite words, what's important is not the message or theme, but how it is portrayed as a game. Even in Cross, it was intentionally made so that the most important question was left unanswered." Kato described the finished story as "ole' boy-meets-girl type of story" with sometimes-shocking twists. Kato rode his motorcycle to relieve the stress of the game's release schedule. He continued refining event data during the final stages of development while the rest of the team undertook debugging and quality control work. Square advertised the game by releasing a short demo of the first chapter with purchases of Legend of Mana. The North American version of Cross required three months of translation and two months of debugging before release. Richard Honeywood translated, working with Kato to rewrite certain dialogue for ease of comprehension in English. He also added instances of wordplay and alliteration to compensate for difficult Japanese jokes. To streamline translation for all 45 playable characters, Honeywood created his own version of the accent generator which needed to be more robust than the simple verbal tics of the Japanese cast. Although the trademark Chrono Cross was registered in the European Union, the game was not released in Europe. Music Chrono Cross was scored by freelance video game music composer Yasunori Mitsuda, who previously worked on Chrono Trigger. Director Masato Kato personally commissioned Mitsuda's involvement, citing a need for the "Chrono sound". Kato envisioned a "Southeast Asian feel, mixed with the foreign tastes and the tones of countries such as Greece"; Mitsuda centered his work around old world cultural influences, including Mediterranean, Fado, Celtic, and percussive African music. Mitsuda cited visual inspiration for songs: "All of my subjects are taken from scenery. I love artwork." To complement the theme of parallel worlds, he gave Another and Home respectively dark |
power. Command economy Planned economies contrast with command economies in that a planned economy is "an economic system in which the government controls and regulates production, distribution, prices, etc." whereas a command economy necessarily has substantial public ownership of industry while also having this type of regulation. In command economies, important allocation decisions are made by government authorities and are imposed by law. This goes against the Marxist understanding of conscious planning. Decentralized planning has been proposed as a basis for socialism and has been variously advocated by anarchists, council communists, libertarian Marxists and other democratic and libertarian socialists who advocate a non-market form of socialism, in total rejection of the type of planning adopted in the economy of the Soviet Union. Most of a command economy is organized in a top-down administrative model by a central authority, where decisions regarding investment and production output requirements are decided upon at the top in the chain of command, with little input from lower levels. Advocates of economic planning have sometimes been staunch critics of these command economies. Leon Trotsky believed that those at the top of the chain of command, regardless of their intellectual capacity, operated without the input and participation of the millions of people who participate in the economy and who understand/respond to local conditions and changes in the economy. Therefore, they would be unable to effectively coordinate all economic activity. Historians have associated planned economies with Marxist–Leninist states and the Soviet economic model. Since the 1980s, it was recognized that the Soviet economic model did not actually constitute a planned economy in that a comprehensive and binding plan did not guide production and investment. The further distinction of an administrative-command system emerged as a new designation in some academic circles for the economic system that existed in the former Soviet Union and Eastern Bloc, highlighting the role of centralized hierarchical decision-making in the absence of popular control over the economy. The possibility of a digital planned economy was explored in Chile between 1971 and 1973 with the development of Project Cybersyn and by Aleksandr Aleksandrovich Kharkevich, head of the Department of Technical Physics in Kiev in 1962. While both economic planning and a planned economy can be either authoritarian or democratic and participatory, democratic socialist critics argue that command economies are necessarily authoritarian or undemocratic in practice. Indicative planning is a form of economic planning in market economies that directs the economy through incentive-based methods. Economic planning can be practiced in a decentralized manner through different government authorities. In some predominantly market-oriented and Western mixed economies, the state utilizes economic planning in strategic industries such as the aerospace industry. Mixed economies usually employ macroeconomic planning while micro-economic affairs are left to the market and price system. Decentralized planning A decentralized-planned economy, occasionally called horizontally-planned economy due to its horizontalism, is a type of planned economy in which the investment and allocation of consumer and capital goods is explicated accordingly to an economy-wide plan built and operatively coordinated through a distributed network of disparate economic agents or even production units itself. Decentralized planning is usually held in contrast to centralized planning, in particular the Soviet-type economic planning of the Soviet Union's command economy, where economic information is aggregated and used to formulate a plan for production, investment and resource allocation by a single central authority. Decentralized planning can take shape both in the context of a mixed economy as well as in a post-capitalist economic system. This form of economic planning implies some process of democratic and participatory decision-making within the economy and within firms itself in the form of industrial democracy. Computer-based forms of democratic economic planning and coordination between economic enterprises have also been proposed by various computer scientists and radical economists. Proponents present decentralized and participatory economic planning as an alternative to market socialism for a post-capitalist society. Decentralized planning has been a feature of anarchist and socialist economics. Variations of decentralized planning such as economic democracy, industrial democracy and participatory economics have been promoted by various political groups, most notably anarchists, democratic socialists, guild socialists, libertarian Marxists, libertarian socialists, revolutionary syndicalists and Trotskyists. During the Spanish Revolution, some areas where anarchist and libertarian socialist influence through the CNT and UGT was extensive, particularly rural regions, were run on the basis of decentralized planning resembling the principles laid out by anarcho-syndicalist Diego Abad de Santillan in the book After the Revolution. Models Negotiated coordination Economist Pat Devine has created a model of decentralized economic planning called "negotiated coordination" which is based upon social ownership of the means of production by those affected by the use of the assets involved, with the allocation of consumer and capital goods made through a participatory form of decision-making by those at the most localized level of production. Moreover, organizations that utilize modularity in their production processes may distribute problem solving and decision making. Participatory planning The planning structure of a decentralized planned economy is generally based on a consumers council and producer council (or jointly, a distributive cooperative) which is sometimes called a consumers' cooperative. Producers and consumers, or | fashion as urban planning in a project called Million Programme, implemented from 1965 to 1974. Some decentralised participation in economic planning occurred across Revolutionary Spain, most notably in Catalonia, during the Spanish Revolution of 1936. Relationship with socialism While socialism is not equivalent to economic planning or to the concept of a planned economy, an influential conception of socialism involves the replacement of capital markets with some form of economic planning in order to achieve ex-ante coordination of the economy. The goal of such an economic system would be to achieve conscious control over the economy by the population, specifically so that the use of the surplus product is controlled by the producers. The specific forms of planning proposed for socialism and their feasibility are subjects of the socialist calculation debate. Computational economic planning In 1959 Anatoly Kitov proposed a distributed computing system (Project "Red Book", ) with a focus on the management of the Soviet economy. Opposition from the Defence Ministry killed Kitov's plan. In 1971 the socialist Allende administration of Chile launched Project Cybersyn to install a telex machine in every corporation and organisation in the economy for the communication of economic data between firms and the government. The data was also fed into a computer-simulated economy for forecasting. A control room was built for real-time observation and management of the overall economy. The prototype-stage of the project showed promise when it was used to redirect supplies around a trucker's strike, but after CIA-backed Augusto Pinochet led a coup in 1973 that established a military dictatorship under his rule the program was abolished and Pinochet moved Chile towards a more liberalized market economy. In their book Towards a New Socialism (1993), the computer scientist Paul Cockshott from the University of Glasgow and the economist Allin Cottrell from the Wake Forest University claim to demonstrate how a democratically planned economy built on modern computer technology is possible and drives the thesis that it would be both economically more stable than the free-market economies and also morally desirable. Cybernetics The use of computers to coordinate production in an optimal fashion has been variously proposed for socialist economies. The Polish economist Oskar Lange (1904-1965) argued that the computer is more efficient than the market process at solving the multitude of simultaneous equations required for allocating economic inputs efficiently (either in terms of physical quantities or monetary prices). Salvador Allende's socialist government pioneered the 1970 Chilean distributed decision support system Project Cybersyn in an attempt to move towards a decentralised planned economy with the experimental viable system model of computed organisational structure of autonomous operative units though an algedonic feedback setting and bottom-up participative decision-making in the form of participative democracy by the Cyberfolk component. Fictional portrayals The 1888 novel Looking Backward by Edward Bellamy depicts a fictional planned economy in a United States around the year 2000 which has become a socialist utopia. The World State in Aldous Huxley's Brave New World (1932) and Airstrip One in George Orwell's Nineteen Eighty-Four (1949) provide fictional depictions of command economies, albeit with diametrically opposed aims. The former is a consumer economy designed to engender productivity while the latter is a shortage economy designed as an agent of totalitarian social control. Airstrip One is organized by the euphemistically named Ministry of Plenty. Other literary portrayals of planned economies include Yevgeny Zamyatin's We (1924), which influenced Orwell's work. Like Nineteen Eighty-Four, Ayn Rand's dystopian 1938 story Anthem offered an artistic portrayal of a command economy that was influenced by We. The difference is that it was a primitivist planned economy as opposed to the advanced technology of We or Brave New World. Central planning Advantages The government can harness land, labour, and capital to serve the economic objectives of the state. Consumer demand can be restrained in favor of greater capital investment for economic development in a desired pattern. In international comparisons, state-socialist nations compared favorably with capitalist nations in health indicators such as infant mortality and life expectancy. However, the reality of this, at least in regards to infant mortality, varied depending on whether official Soviet statistics or WHO definitions were used. In Socialist China under Mao China's growth in life expectancy between 1950 and 1980 ranks as among the most rapid sustained increases in documented global history. The state can begin building massive heavy industries at once in an underdeveloped economy without waiting years for capital to accumulate through the expansion of light industry and without reliance on external financing. This is what happened in the Soviet Union during the 1930s when the government forced the share of gross national income dedicated to private consumption down from 80% to 50%. As a result of this development, the Soviet Union experienced massive growth in heavy industry, with a concurrent massive contraction of its agricultural sector due to the labour shortage. Disadvantages Economic instability Studies of command economies of the Eastern Bloc in the 1950s and 1960s by both American and Eastern European economists found that contrary to the expectations of both groups they showed greater fluctuations in output than market economies during the same period. Inefficient resource distribution Critics of planned economies argue that planners cannot detect consumer preferences, shortages and surpluses with sufficient accuracy and therefore cannot efficiently co-ordinate production (in a market economy, a free price system is intended to serve this purpose). This difficulty was notably written about by economists Ludwig von Mises and Friedrich Hayek, who referred to subtly distinct aspects of the problem as the economic calculation problem and local knowledge problem, respectively. Whereas the former stressed the theoretical underpinnings of a market economy to subjective value theory while attacking the labor theory of value, the latter argued that the only way to satisfy individuals who have a constantly changing hierarchy of needs and are the only ones to possess their particular individual's circumstances is by allowing those with the most knowledge of their needs to have it in their power to use their resources in a competing marketplace to meet the needs of the most consumers most efficiently. This phenomenon is recognized as spontaneous order. Additionally, misallocation of resources would naturally ensue by redirecting capital away from individuals with direct knowledge and circumventing it into markets where a coercive monopoly influences behavior, ignoring market signals. According to Tibor Machan, "[w]ithout a market in which allocations can be made in obedience to the law of supply and demand, it is difficult or impossible to funnel resources with respect to actual human preferences and goals". Suppression of economic democracy and self-management Economist Robin Hahnel, who supports participatory economics, a form of socialist decentralized planned economy, notes that even if central planning overcame its inherent inhibitions of incentives and innovation, it would nevertheless be unable to maximize economic democracy and self-management, which he believes are concepts that are more intellectually coherent, consistent and just than mainstream notions of economic freedom. Furthermore, Hahnel states: Combined with a more democratic political system, and redone to closer approximate a best case version, centrally planned economies no doubt would have performed better. But they could never have delivered economic self-management, they would always have been slow to innovate as apathy and frustration took their inevitable toll, and they would always have been susceptible to growing inequities and inefficiencies as the effects of differential economic power grew. Under central planning neither planners, managers, nor workers had incentives to promote the social economic interest. Nor did impeding markets for final goods to the planning system enfranchise consumers in meaningful ways. But central planning would have been incompatible with economic democracy even if it had overcome its information and incentive liabilities. And the truth is that it survived as long as it did only because it was propped up by unprecedented totalitarian political power. Command economy Planned economies contrast with command economies |
and lower region. The skin may range from pale to dark, and females develop swelling pink skin when in oestrus. Chimpanzees are adapted for both arboreal and terrestrial locomotion. Arboreal locomotion consists of vertical climbing and brachiation. On the ground chimpanzees move both quadrupedally and bipedally, which appear to have similar energy costs. As with bonobos and gorillas, chimpanzees move quadrupedally by knuckle-walking, which probably evolved independently in Pan and Gorilla. The physical strength of chimps is around 1.5 times greater than humans due to higher content of fast twitch muscle fibres, one of the chimpanzee's adaptations for climbing and swinging. According to Japan's Asahiyama Zoo, the grip strength of an adult chimpanzee is estimated to be 200 kg (441 lb), while other sources claim figures of up to 330 kg (727 lb). Ecology The chimpanzee is a highly adaptable species. It lives in a variety of habitats, including dry savanna, evergreen rainforest, montane forest, swamp forest and dry woodland-savanna mosaic. In Gombe, the chimpanzee mostly uses semideciduous and evergreen forest as well as open woodland. At Bossou, the chimpanzee inhabits multistage secondary deciduous forest, which has grown after shifting cultivation, as well as primary forest and grassland. At Taï, it is found in the last remaining tropical rain forest in Ivory Coast. The chimpanzee has an advanced cognitive map of its home range and can repeatedly find food. The chimpanzee builds a sleeping nest in a tree in a different location each night, never using the same nest more than once. Chimpanzees sleep alone in separate nests except for infants or juvenile chimpanzees, which sleep with their mothers. Diet The chimpanzee is an omnivorous frugivore. It prefers fruit above all other food items but also eats leaves and leaf buds, seeds, blossoms, stems, pith, bark and resin. A study in Budongo Forest, Uganda found that 64.5% of their feeding time concentrated on fruits (84.6% of which being ripe), particularly those from two species of Ficus, Maesopsis eminii and Celtis durandii. In addition, 19% of feeding time was spent on arboreal leaves, mostly Broussonetia papyrifera and Celtis mildbraedii. While the chimpanzee is mostly herbivorous, it does eat honey, soil, insects, birds and their eggs, and small to medium-sized mammals, including other primates. Insect species consumed include the weaver ant Oecophylla longinoda, Macrotermes termites and honey bees. The red colobus ranks at the top of preferred mammal prey. Other mammalian prey include red-tailed monkeys, infant and juvenile yellow baboons, bush babies, blue duikers, bushbucks, and common warthogs. Despite the fact that chimpanzees are known to hunt, and to collect insects and other invertebrates, such food actually makes up a very small portion of their diet, from as little as 2% yearly to as much as 65 grams of animal flesh per day for each adult chimpanzee in peak hunting seasons. This also varies from troop to troop and year to year. However, in all cases, the majority of their diet consists of fruits, leaves, roots, and other plant matter. Female chimpanzees appear to consume much less animal flesh than males, according to several studies. Jane Goodall documented many occasions within Gombe Stream National Park of chimpanzees and western red colobus monkeys ignoring each other despite close proximity. Chimpanzees do not appear to directly compete with gorillas in areas where they overlap. When fruit is abundant gorilla and chimpanzee diets converge, but when fruit is scarce gorillas resort to vegetation. The two apes may also feed on different species, whether fruit or insects. Chimpanzees and gorillas usually ignore or avoid each other when feeding on the same tree, but coalitions of chimpanzees have been observed attacking families of gorillas including silverbacks and killing infants. Mortality and health The average lifespan of a chimpanzee in the wild is relatively short, usually less than 15 years, although individuals that reach 12 years may live an additional 15. Wild individuals may live over 25 years and on rare occasions, around 60 years. Captive chimpanzees tend to live longer, with median lifespans of 31.7 years for males and 38.7 years for females. The oldest known male captive chimpanzee to have been documented lived to 66 years, and the oldest female, Little Mama, was over 70 years old. Leopards prey on chimpanzees in some areas. It is possible that much of the mortality caused by leopards can be attributed to individuals that have specialised in chimp-killing. Chimpanzees may react to a leopard's presence with loud vocalising, branch shaking and throwing objects. There is at least one record of chimpanzees killing a leopard cub, after mobbing it and its mother in their den. Four chimpanzees could have fallen prey to lions at Mahale Mountains National Park. Although no other instances of lion predation on chimpanzees have been recorded, lions likely do kill chimpanzees occasionally and the larger group sizes of savanna chimpanzees may have developed as a response to threats from these big cats. Chimpanzees may react to lions by fleeing up trees, vocalising or hiding in silence. Chimpanzees and humans share only 50% of their parasite and microbe species. This is due to the differences in environmental and dietary adaptations; human internal parasite species overlap more with omnivorous, savanna-dwelling baboons. The chimpanzee is host to the louse species Pediculus schaeffi, a close relative of P. humanus which infests human head and body hair. By contrast, the human pubic louse Pthirus pubis is closely related to Pthirus gorillae which infests gorillas. A 2017 study of gastrointestinal parasites of wild chimpanzees in degraded forest in Uganda found nine species of protozoa, five nematodes, one cestode, and one trematode. The most prevalent species was the protozoan Troglodytella abrassarti. Behaviour Recent studies have suggested that human observers influence chimpanzee behavior. One suggestion is that drones, camera traps and remote microphones should be used to record and monitor chimpanzees rather than direct observation. Group structure Chimpanzees live in communities that typically range from around 20 to more than 150 members, but spend most of their time travelling in small, temporary groups consisting of a few individuals, which may consist of any combination of age and sex classes. Both males and females sometimes travel alone. This fission-fusion society may include groups of four types: all-male, adult females and offspring, both sexes, or one female and her offspring. These smaller groups emerge in a variety of types, for a variety of purposes. For example, an all-male troop may be organised to hunt for meat, while a group consisting of lactating females serves to act as a "nursery group" for the young. At the core of social structures are males, which patrol the territory, protect group members, and search for food. Males remain in their natal communities, while females generally emigrate at adolescence. Males in a community are more likely to be related to one another than females are to each other. Among males there is generally a dominance hierarchy, and males are dominant over females. However, this unusual fission-fusion social structure, "in which portions of the parent group may on a regular basis separate from and then rejoin the rest," is highly variable in terms of which particular individual chimpanzees congregate at a given time. This is caused mainly by the large measure of individual autonomy that individuals have within their fission-fusion social groups. As a result, individual chimpanzees often forage for food alone, or in smaller groups as opposed to the much larger "parent" group, which encompasses all the chimpanzees which regularly come into contact and congregate into parties in a particular area. Male chimpanzees exist in a linear dominance hierarchy. Top-ranking males tend to be aggressive even during dominance stability. This is probably due to the chimpanzee's fission-fusion society, with male chimpanzees leaving groups and returning after extended periods of time. With this, a dominant male is unsure if any "political maneuvering" has occurred in his absence and must re-establish his dominance. Thus, a large amount of aggression occurs within five to fifteen minutes after a reunion. During these encounters, displays of aggression are generally preferred over physical attacks. Males maintain and improve their social ranks by forming coalitions, which have been characterised as "exploitative" and are based on an individual's influence in agonistic interactions. Being in a coalition allows males to dominate a third individual when they could not by themselves, as politically apt chimpanzees can exert power over aggressive interactions regardless of their rank. Coalitions can also give an individual male the confidence to challenge a dominant or larger male. The more allies a male has, the better his chance of becoming dominant. However, most changes in hierarchical rank are caused by dyadic interactions. Chimpanzee alliances can be very fickle and one member may suddenly turn on another if it is to his advantage. Low-ranking males frequently switch sides in disputes between more dominant individuals. Low-ranking males benefit from an unstable hierarchy and often find increased sexual opportunities if a dispute or conflict occurs. In addition, conflicts between dominant males cause them to focus on each other rather than the lower-ranking males. Social hierarchies among adult females tend to be weaker. Nevertheless, the status of an adult female may be important for her offspring. Females in Taï have also been recorded to form alliances. While chimpanzee social structure is often referred to as patriarchal, it is not entirely unheard of for females to forge coalitions against males. There is also at least one recorded case of females securing a dominant position over males in their respective troop, albeit in a captive environment. Social grooming appears to be important in the formation and maintenance of coalitions. It is more common among adult males than adult females and between males and females. Chimpanzees have been described as highly territorial and will frequently kill other chimpanzees, although Margaret Power wrote in her 1991 book The Egalitarians that the field studies from which the aggressive data came, Gombe and Mahale, used artificial feeding systems that increased aggression in the chimpanzee populations studied, and might not reflect innate characteristics of the species as a whole as such. In the years following her artificial feeding conditions at Gombe, Jane Goodall described groups of male chimpanzees patrolling the borders of their territory, brutally attacking chimpanzees that had split off from the Gombe group. A study published in 2010 found that the chimpanzees wage wars over territory, not mates. Patrols from smaller groups are more likely to avoid contact with their neighbours. Patrols from large groups even take over a smaller group's territory, gaining access to more resources, food, and females. While it was traditionally accepted that only female chimpanzees immigrate and males remain in their natal troop for life, there are confirmed cases of adult males safely integrating themselves into new communities among West African chimpanzees, suggesting they are less territorial than other subspecies. Mating and parenting Chimpanzees mate throughout the year, although the number of females in oestrus varies seasonally in a group. Female chimpanzees are more likely to come into oestrus when food is readily available. Oestrous females exhibit sexual swellings. Chimpanzees are promiscuous; during oestrus, females mate with several males in their community, while males have large testicles for sperm competition. Other forms of mating also exist. A community's dominant males sometimes restrict reproductive access to females. A male and female can form a consortship and mate outside their community. In addition, females sometimes leave their community and mate with males from neighboring communities. These alternative mating strategies give females more mating opportunities without losing the support of the males in their community. Infanticide has been recorded in chimpanzee communities in some areas and the victims are often consumed. Male chimpanzees practice infanticide on unrelated young to shorten the interbirth intervals in the females. Females sometimes practice infanticide; this may be related to the dominance hierarchy in females, or may simply be pathological. Copulation is brief, lasting approximately seven seconds. The gestation period is eight months. Care for the young is provided mostly by their mothers. The survival and emotional health of the young is dependent on maternal care. Mothers provide their young with food, warmth, and protection, and teach them certain skills. In addition, a chimpanzee's future rank may be dependent on its mother's status. Newborn chimpanzees are helpless; their grasping reflex is not strong enough to support them for more than a few seconds. For their first 30 days, infants cling to their mother's bellies. Infants are unable to support their own weight for their first two months and need their mothers' support. When they reach five to six months, infants ride on their mothers' backs. They remain in continual contact for the rest of their first year. When they reach two years of age, they are able to move and sit independently, and start moving beyond the arms' reach of their mothers. By four to six years, chimpanzees are weaned and infancy ends. The juvenile period for chimpanzees lasts from their sixth to ninth years. Juveniles remain close to their mothers, but interact an increasing amount with other members of their community. Adolescent females move between groups and are supported by their mothers in agonistic encounters. Adolescent males spend time with adult males in social activities like hunting and boundary patrolling. A captive study suggests males can safely immigrate to a new group if accompanied by immigrant females who have an existing relationship with this male. This gives the resident males reproductive advantages with these females, as they are more inclined to remain in the group if their male friend is also accepted. Communication Chimpanzees use facial expressions, postures, and sounds to communicate with each other. Chimpanzees have expressive faces that are important in close-up communications. When frightened, a "full closed grin" causes nearby individuals to be fearful, as well. Playful chimpanzees display an open-mouthed grin. Chimpanzees may also express themselves with the "pout", which is made in distress, the "sneer", which is made when threatening or fearful, and "compressed-lips face", which is a type of display. When submitting to a dominant individual, a chimpanzee crunches, bobs, and extends a hand. When in an aggressive mode, a chimpanzee swaggers bipedally, hunched over and arms waving, in an attempt to exaggerate its size. While travelling, chimpanzees keep in contact by beating their hands and feet against the trunks of large trees, an act that is known as "drumming". They also do this when encountering individuals from other communities. Vocalisations are also important in chimpanzee communication. The most common call in adults is the "pant-hoot", which may signal social rank and bond along with keeping groups together. Pant-hoots are made | of gorillas. Chimpanzee bodies are covered by coarse hair, except for the face, fingers, toes, palms of the hands, and soles of the feet. Chimpanzees lose more hair as they age, and develop bald spots. The hair of a chimpanzee is typically black but can be brown or ginger. As they get older, white or grey patches may appear, particularly on the chin and lower region. The skin may range from pale to dark, and females develop swelling pink skin when in oestrus. Chimpanzees are adapted for both arboreal and terrestrial locomotion. Arboreal locomotion consists of vertical climbing and brachiation. On the ground chimpanzees move both quadrupedally and bipedally, which appear to have similar energy costs. As with bonobos and gorillas, chimpanzees move quadrupedally by knuckle-walking, which probably evolved independently in Pan and Gorilla. The physical strength of chimps is around 1.5 times greater than humans due to higher content of fast twitch muscle fibres, one of the chimpanzee's adaptations for climbing and swinging. According to Japan's Asahiyama Zoo, the grip strength of an adult chimpanzee is estimated to be 200 kg (441 lb), while other sources claim figures of up to 330 kg (727 lb). Ecology The chimpanzee is a highly adaptable species. It lives in a variety of habitats, including dry savanna, evergreen rainforest, montane forest, swamp forest and dry woodland-savanna mosaic. In Gombe, the chimpanzee mostly uses semideciduous and evergreen forest as well as open woodland. At Bossou, the chimpanzee inhabits multistage secondary deciduous forest, which has grown after shifting cultivation, as well as primary forest and grassland. At Taï, it is found in the last remaining tropical rain forest in Ivory Coast. The chimpanzee has an advanced cognitive map of its home range and can repeatedly find food. The chimpanzee builds a sleeping nest in a tree in a different location each night, never using the same nest more than once. Chimpanzees sleep alone in separate nests except for infants or juvenile chimpanzees, which sleep with their mothers. Diet The chimpanzee is an omnivorous frugivore. It prefers fruit above all other food items but also eats leaves and leaf buds, seeds, blossoms, stems, pith, bark and resin. A study in Budongo Forest, Uganda found that 64.5% of their feeding time concentrated on fruits (84.6% of which being ripe), particularly those from two species of Ficus, Maesopsis eminii and Celtis durandii. In addition, 19% of feeding time was spent on arboreal leaves, mostly Broussonetia papyrifera and Celtis mildbraedii. While the chimpanzee is mostly herbivorous, it does eat honey, soil, insects, birds and their eggs, and small to medium-sized mammals, including other primates. Insect species consumed include the weaver ant Oecophylla longinoda, Macrotermes termites and honey bees. The red colobus ranks at the top of preferred mammal prey. Other mammalian prey include red-tailed monkeys, infant and juvenile yellow baboons, bush babies, blue duikers, bushbucks, and common warthogs. Despite the fact that chimpanzees are known to hunt, and to collect insects and other invertebrates, such food actually makes up a very small portion of their diet, from as little as 2% yearly to as much as 65 grams of animal flesh per day for each adult chimpanzee in peak hunting seasons. This also varies from troop to troop and year to year. However, in all cases, the majority of their diet consists of fruits, leaves, roots, and other plant matter. Female chimpanzees appear to consume much less animal flesh than males, according to several studies. Jane Goodall documented many occasions within Gombe Stream National Park of chimpanzees and western red colobus monkeys ignoring each other despite close proximity. Chimpanzees do not appear to directly compete with gorillas in areas where they overlap. When fruit is abundant gorilla and chimpanzee diets converge, but when fruit is scarce gorillas resort to vegetation. The two apes may also feed on different species, whether fruit or insects. Chimpanzees and gorillas usually ignore or avoid each other when feeding on the same tree, but coalitions of chimpanzees have been observed attacking families of gorillas including silverbacks and killing infants. Mortality and health The average lifespan of a chimpanzee in the wild is relatively short, usually less than 15 years, although individuals that reach 12 years may live an additional 15. Wild individuals may live over 25 years and on rare occasions, around 60 years. Captive chimpanzees tend to live longer, with median lifespans of 31.7 years for males and 38.7 years for females. The oldest known male captive chimpanzee to have been documented lived to 66 years, and the oldest female, Little Mama, was over 70 years old. Leopards prey on chimpanzees in some areas. It is possible that much of the mortality caused by leopards can be attributed to individuals that have specialised in chimp-killing. Chimpanzees may react to a leopard's presence with loud vocalising, branch shaking and throwing objects. There is at least one record of chimpanzees killing a leopard cub, after mobbing it and its mother in their den. Four chimpanzees could have fallen prey to lions at Mahale Mountains National Park. Although no other instances of lion predation on chimpanzees have been recorded, lions likely do kill chimpanzees occasionally and the larger group sizes of savanna chimpanzees may have developed as a response to threats from these big cats. Chimpanzees may react to lions by fleeing up trees, vocalising or hiding in silence. Chimpanzees and humans share only 50% of their parasite and microbe species. This is due to the differences in environmental and dietary adaptations; human internal parasite species overlap more with omnivorous, savanna-dwelling baboons. The chimpanzee is host to the louse species Pediculus schaeffi, a close relative of P. humanus which infests human head and body hair. By contrast, the human pubic louse Pthirus pubis is closely related to Pthirus gorillae which infests gorillas. A 2017 study of gastrointestinal parasites of wild chimpanzees in degraded forest in Uganda found nine species of protozoa, five nematodes, one cestode, and one trematode. The most prevalent species was the protozoan Troglodytella abrassarti. Behaviour Recent studies have suggested that human observers influence chimpanzee behavior. One suggestion is that drones, camera traps and remote microphones should be used to record and monitor chimpanzees rather than direct observation. Group structure Chimpanzees live in communities that typically range from around 20 to more than 150 members, but spend most of their time travelling in small, temporary groups consisting of a few individuals, which may consist of any combination of age and sex classes. Both males and females sometimes travel alone. This fission-fusion society may include groups of four types: all-male, adult females and offspring, both sexes, or one female and her offspring. These smaller groups emerge in a variety of types, for a variety of purposes. For example, an all-male troop may be organised to hunt for meat, while a group consisting of lactating females serves to act as a "nursery group" for the young. At the core of social structures are males, which patrol the territory, protect group members, and search for food. Males remain in their natal communities, while females generally emigrate at adolescence. Males in a community are more likely to be related to one another than females are to each other. Among males there is generally a dominance hierarchy, and males are dominant over females. However, this unusual fission-fusion social structure, "in which portions of the parent group may on a regular basis separate from and then rejoin the rest," is highly variable in terms of which particular individual chimpanzees congregate at a given time. This is caused mainly by the large measure of individual autonomy that individuals have within their fission-fusion social groups. As a result, individual chimpanzees often forage for food alone, or in smaller groups as opposed to the much larger "parent" group, which encompasses all the chimpanzees which regularly come into contact and congregate into parties in a particular area. Male chimpanzees exist in a linear dominance hierarchy. Top-ranking males tend to be aggressive even during dominance stability. This is probably due to the chimpanzee's fission-fusion society, with male chimpanzees leaving groups and returning after extended periods of time. With this, a dominant male is unsure if any "political maneuvering" has occurred in his absence and must re-establish his dominance. Thus, a large amount of aggression occurs within five to fifteen minutes after a reunion. During these encounters, displays of aggression are generally preferred over physical attacks. Males maintain and improve their social ranks by forming coalitions, which have been characterised as "exploitative" and are based on an individual's influence in agonistic interactions. Being in a coalition allows males to dominate a third individual when they could not by themselves, as politically apt chimpanzees can exert power over aggressive interactions regardless of their rank. Coalitions can also give an individual male the confidence to challenge a dominant or larger male. The more allies a male has, the better his chance of becoming dominant. However, most changes in hierarchical rank are caused by dyadic interactions. Chimpanzee alliances can be very fickle and one member may suddenly turn on another if it is to his advantage. Low-ranking males frequently switch sides in disputes between more dominant individuals. Low-ranking males benefit from an unstable hierarchy and often find increased sexual opportunities if a dispute or conflict occurs. In addition, conflicts between dominant males cause them to focus on each other rather than the lower-ranking males. Social hierarchies among adult females tend to be weaker. Nevertheless, the status of an adult female may be important for her offspring. Females in Taï have also been recorded to form alliances. While chimpanzee social structure is often referred to as patriarchal, it is not entirely unheard of for females to forge coalitions against males. There is also at least one recorded case of females securing a dominant position over males in their respective troop, albeit in a captive environment. Social grooming appears to be important in the formation and maintenance of coalitions. It is more common among adult males than adult females and between males and females. Chimpanzees have been described as highly territorial and will frequently kill other chimpanzees, although Margaret Power wrote in her 1991 book The Egalitarians that the field studies from which the aggressive data came, Gombe and Mahale, used artificial feeding systems that increased aggression in the chimpanzee populations studied, and might not reflect innate characteristics of the species as a whole as such. In the years following her artificial feeding conditions at Gombe, Jane Goodall described groups of male chimpanzees patrolling the borders of their territory, brutally attacking chimpanzees that had split off from the Gombe group. A study published in 2010 found that the chimpanzees wage wars over territory, not mates. Patrols from smaller groups are more likely to avoid contact with their neighbours. Patrols from large groups even take over a smaller group's territory, gaining access to more resources, food, and females. While it was traditionally accepted that only female chimpanzees immigrate and males remain in their natal troop for life, there are confirmed cases of adult males safely integrating themselves into new communities among West African chimpanzees, suggesting they are less territorial than other subspecies. Mating and parenting Chimpanzees mate throughout the year, although the number of females in oestrus varies seasonally in a group. Female chimpanzees are more likely to come into oestrus when food is readily available. Oestrous females exhibit sexual swellings. Chimpanzees are promiscuous; during oestrus, females mate with several males in their community, while males have large testicles for sperm competition. Other forms of mating also exist. A community's dominant males sometimes restrict reproductive access to females. A male and female can form a consortship and mate outside their community. In addition, females sometimes leave their community and mate with males from neighboring communities. These alternative mating strategies give females more mating opportunities without losing the support of the males in their community. Infanticide has been recorded in chimpanzee communities in some areas and the victims are often consumed. Male chimpanzees practice infanticide on unrelated young to shorten the interbirth intervals in the females. Females sometimes practice infanticide; this may be related to the dominance hierarchy in females, or may simply be pathological. Copulation is brief, lasting approximately seven seconds. The gestation period is eight months. Care for the young is provided mostly by their mothers. The survival and emotional health of the young is dependent on maternal care. Mothers provide their young with food, warmth, and protection, and teach them certain skills. In addition, a chimpanzee's future rank may be dependent on its mother's status. Newborn chimpanzees are helpless; their grasping reflex is not strong enough to support them for more than a few seconds. For their first 30 days, infants cling to their mother's bellies. Infants are unable to support their own weight for their first two months and need their mothers' support. When they reach five to six months, infants ride on their mothers' backs. They remain in continual contact for the rest of their first year. When they reach two years of age, they are able to move and sit independently, and start moving beyond the arms' reach of their mothers. By four to six years, chimpanzees are weaned and infancy ends. The juvenile period for chimpanzees lasts from their sixth to ninth years. Juveniles remain close to their mothers, but interact an increasing amount with other members of their community. Adolescent females move between groups and are supported by their mothers in agonistic encounters. Adolescent males spend time with adult males in social activities like hunting and boundary patrolling. A captive study suggests males can safely immigrate to a new group if accompanied by immigrant females who have an existing relationship with this male. This gives the resident males reproductive advantages with these females, as they are more inclined to remain in the group if their male friend is also accepted. Communication Chimpanzees use facial expressions, postures, and sounds to communicate with each other. Chimpanzees have expressive faces that are important in close-up communications. When frightened, a "full closed grin" causes nearby individuals to be fearful, as well. Playful chimpanzees display an open-mouthed grin. Chimpanzees may also express themselves with the "pout", which is made in distress, the "sneer", which is made when threatening or fearful, and "compressed-lips face", which is a type of display. When submitting to a dominant individual, a chimpanzee crunches, bobs, and extends a hand. When in an aggressive mode, a chimpanzee swaggers bipedally, hunched over and arms waving, in an attempt to exaggerate its size. While travelling, chimpanzees keep in contact by beating their hands and feet against the trunks of large trees, an act that is known as "drumming". They also do this when encountering individuals from other communities. Vocalisations are also important in chimpanzee communication. The most common call in adults is the "pant-hoot", which may signal social rank and bond along with keeping groups together. Pant-hoots are made of four parts, starting with soft "hoos", the introduction; that gets louder and louder, the build-up; and climax into screams and sometimes barks; these die down back to soft "hoos" during the letdown phase as the call ends. Grunting is made in situations like feeding and greeting. Submissive individuals make "pant-grunts" towards their superiors. Whimpering is made by young chimpanzees as a form of begging or when lost from the group. Chimpanzees use distance calls to draw attention to danger, food sources, or other community members. "Barks" may be made as "short barks" when hunting and "tonal barks" when sighting large snakes. Hunting When hunting small monkeys such as the red colobus, chimpanzees hunt where the forest canopy is interrupted or irregular. This allows them to easily corner the monkeys when chasing them in the appropriate direction. Chimpanzees may also hunt as a coordinated team, so that they can corner their prey even in a continuous canopy. During an arboreal hunt, each chimpanzee in the hunting groups has a role. "Drivers" serve to keep the prey running in a certain direction and follow them without attempting to make a catch. "Blockers" are stationed at the bottom of the trees and climb up to block prey that takes off in a different direction. "Chasers" move quickly and try to make a catch. Finally, "ambushers" hide and rush out when a monkey nears. While both adults and infants are taken, adult male colobus monkeys will attack the hunting chimps. Male chimpanzees hunt more than females. When caught and killed, the meal is distributed to all hunting party members and even bystanders. Intelligence and cognition Chimpanzees display numerous signs of intelligence, from the ability to remember symbols to cooperation, tool use, and perhaps language. They are among species that have passed the mirror test, suggesting self-awareness. In one study, two young chimpanzees showed retention of mirror self-recognition after one year without access to mirrors. Chimpanzees have been observed to use insects to treat their own wounds and those of others. They catch them as apply them directly to the injury. Chimpanzees also display signs of culture among groups, with the learning and transmission of variations in grooming, tool use and foraging techniques leading to localized traditions. A 30-year study at Kyoto University's Primate Research Institute has shown that chimpanzees are able to learn to recognise the numbers 1 to 9 and their values. The chimpanzees further show an aptitude for eidetic memory, demonstrated in experiments in which the jumbled digits are flashed onto a computer screen for less than a quarter of a second. One chimpanzee, Ayumu, was able to correctly and quickly point to the positions where they appeared in ascending order. Ayumu performed better than human adults who were given the same test. In controlled experiments on cooperation, chimpanzees show a basic understanding of cooperation, and recruit the best collaborators. In a group setting with a device that delivered food rewards only to cooperating chimpanzees, cooperation first increased, then, due to competitive behaviour, decreased, before finally increasing to the highest level through punishment and other arbitrage behaviours. Great apes show laughter-like vocalisations in response to physical contact, such as wrestling, play chasing, or tickling. This is documented in wild and captive chimpanzees. Chimpanzee laughter is not readily recognisable to humans as such, because it is generated by alternating inhalations and exhalations that sound more like breathing and panting. Instances in which nonhuman primates have expressed joy have been reported. Humans and chimpanzees share similar ticklish areas of the body, such as the armpits and belly. The enjoyment of tickling in chimpanzees does not diminish with age. Chimpanzees have displayed different behaviours in response to a dying or dead group member. When witnessing a sudden death, the other group members act in frenzy, with vocalisations, aggressive displays, and touching of the corpse. In one case chimpanzees cared for a dying elder, then attended and cleaned the corpse. Afterward, they avoided the spot where the elder died and behaved in a more subdued manner. Mothers have been reported to carry around and groom their dead infants for several days. Experimenters now and then witness behaviour that cannot be readily reconciled with chimpanzee intelligence or theory of mind. Wolfgang Köhler, for instance, reported insightful behaviour in chimpanzees, but he likewise often observed that they experienced "special difficulty" in solving simple problems. Researchers also reported that, when faced with a choice between two persons, chimpanzees were just as likely to beg |
gap junctions that interrupt molecular exchange and signal transport. The mutation can appear in GJB1 coding for connexin 32, a gap junction protein expressed in Schwann cells. Because this protein is also present in oligodendrocytes, demyelination can appear in the CNS. Schwann cells create the myelin sheath, by wrapping its plasma membrane around the axon. Neurons, Schwann cells, and fibroblasts work together to create a functional nerve. Schwann cells and neurons exchange molecular signals by gap junctions that regulate survival and differentiation. Demyelinating Schwann cells causes abnormal axon structure and function. They may cause axon degeneration, or they may simply cause axons to malfunction. The myelin sheath allows nerve cells to conduct signals faster. When the myelin sheath is damaged, nerve signals are slower, and this can be measured by a common neurological test, electromyography. When the axon is damaged, though, this results in a reduced compound muscle action potential. Diagnosis CMT can be diagnosed through three different forms of tests: measurement of the speed of nerve impulses (nerve conduction studies), a biopsy of the nerve, and DNA testing. DNA testing can give a definitive diagnosis, but not all the genetic markers for CMT are known. CMT is first most noticed when someone develops lower leg weakness, such as foot drop, or foot deformities, including hammertoes and high arches, but signs alone do not lead to diagnosis. Patients must be referred to a physician specialising in neurology or rehabilitation medicine. To see signs of muscle weakness, the neurologist may ask patients to walk on their heels or to move part of their leg against an opposing force. To identify sensory loss, the neurologist tests for deep-tendon reflexes, such as the knee jerk, which are reduced or absent in CMT. The doctor may also ask the patient's family history since CMT is hereditary. The lack of family history does not rule out CMT, but is helpful to rule out other causes of neuropathy, such as diabetes or exposure to certain chemicals or drugs. In 2010, CMT was one of the first diseases where the genetic cause of a particular patient's disease was precisely determined by sequencing the whole genome of an affected individual. This was done by the scientists employed by the Charcot Marie Tooth Association (CMTA). Two mutations were identified in a gene, SH3TC2, known to cause CMT. Researchers then compared the affected patient's genome to the genomes of the patient's mother, father, and seven siblings with and without the disease. The mother and father each had one normal and one mutant copy of this gene, and had mild or no symptoms. The offspring who inherited two mutant genes presented fully with the disease. Histology The constant cycle of demyelination and remyelination, which occurs in CMT, can lead to the formation of layers of myelin around some nerves, termed an "onion bulb". These are also seen in chronic inflammatory demyelinating polyneuropathy. Muscles show fiber type grouping, a similarly nonspecific finding that indicates a cycle of denervation/reinnervation. Normally, type I and type II muscle fibers show a checkerboard-like random distribution. However, when reinnervation occurs, the group of fibers associated with one nerve are of the same type. The standard for indicating fiber type is histoenzymatic adenosine triphosphatase (ATPase at pH 9.4). Management Often, the most important goal for patients with CMT is to maintain movement, muscle strength, and flexibility. Therefore, an interprofessional team approach with occupational therapy (OT), physical therapy (PT), orthotist, podiatrist, and or orthopedic surgeon is recommended. PT typically focuses on muscle-strength training, muscle stretching, and aerobic exercise, while OT can provide education on energy conservation strategies and activities of daily living. Physical therapy should be involved in designing an exercise program that fits a person's personal strengths and flexibility. Bracing can also be used to correct problems caused by CMT. An orthotist may address gait abnormalities by prescribing the use of orthotics. Appropriate footwear is also very important for people with CMT, but they often have difficulty finding well-fitting shoes because of their high arched feet and hammer toes. Due to the lack of good sensory reception in the feet, CMT patients may also need to see a podiatrist for assistance in trimming nails or removing calluses that develop on the pads of the feet. Lastly, patients can also decide to have surgery performed by a podiatrist or an orthopedic surgeon. Surgery may help to stabilize the patients' feet or correct progressive problems. These procedures include straightening and pinning the toes, lowering the arch, and sometimes, fusing the ankle joint to provide stability. CMT patients must take extra care to avoid falling as fractures take longer to heal in someone with an underlying disease process. Additionally, the resulting inactivity may cause the CMT to worsen. The Charcot–Marie–Tooth Association classifies the chemotherapy drug vincristine as a "definite high risk" and states, "vincristine has been proven hazardous and should be avoided by all CMT patients, including those with no symptoms." Several corrective surgical procedures can be done to improve the physical condition of the affected individuals.

Several corrective surgical procedures can be done to improve the physical condition of the affected individuals. Orthotics If the muscles of the lower extremities are weak, it makes sense to prescribe custom-fabricated orthotics. Depending on which muscle groups are affected, the right orthoses with the appropriate functional elements should be prescribed. A weakness of the Musculus tibialis anterior, which lifts the feet, is usually accompanied by an atrophy of the Musculus gastrocnemius which, together with the Musculus soleus, forms the Musculus triceps surae (distal calf muscles), occurs causing the known “stork leg deformity”. In most cases, ankle-foot orthoses that have functional elements for the foot lifting and adjustable control of the lowering of the forefoot make sense. Weak calf muscles lead to insufficient activation of the forefoot lever. This leads to an additional increasing uncertainty when standing and walking. If the calf muscles are weak, an orthosis should therefore be equipped with functional elements to activate the forefoot lever. An orthotic joint with an adjustable dynamic dorsiflexion stop with strong spring in combination with a lower leg shell in front of the shin is recommended for this. Such orthoses help to control foot drop, instability of the foot and ankle and offer the patient a better sense of balance when standing and walking without restricting mobility and the dynamics of the ankle joint. Studies confirm the positive effect of orthoses with adjustable functional elements in patients with paralysis of these muscle groups. It is of great advantage if the resistances of the two functional elements can be set separately from one another in the two directions of movement, dorsiflexion and plantar flexion. Prognosis The severity of symptoms varies widely even for the same type of CMT. Cases of monozygotic twins with varying levels of disease severity have been reported, showing that identical genotypes are associated with different levels of severity (see penetrance). Some patients are able to live a normal life and are almost or entirely asymptomatic. A 2007 review stated that, "life expectancy is not known to be altered in the majority of cases." History The disease is named after those who classically described it: the Frenchman Jean-Martin Charcot (1825–1893), his pupil Pierre Marie (1853–1940), and the Briton Howard Henry Tooth (1856–1925).

vomiting, confusion, headache and seizures. These symptoms may resolve with normalisation of the serum sodium concentration. Three to five days later, a second phase of neurological manifestations occurs correlating with the onset of myelinolysis. Observable immediate precursors may include seizures, disturbed consciousness, gait changes, and decrease or cessation of respiratory function. The classical clinical presentation is the progressive development of spastic quadriparesis, pseudobulbar palsy, and emotional lability (pseudobulbar affect), with other more variable neurological features associated with brainstem damage. These result from a rapid myelinolysis of the corticobulbar and corticospinal tracts in the brainstem. In about ten per cent of people with central pontine myelinolysis, extrapontine myelinolysis is also found. In these cases symptoms of Parkinson's disease may be generated. Causes The most common cause is overly-rapid correction of low blood sodium levels (hyponatremia). Apart from rapid correction of hyponatraemia, there are case reports of central pontine myelinolysis in association with hypokalaemia, anorexia nervosa when feeding is started, patients undergoing dialysis and burn victims. There is a case report of central pontine myelinolysis occurring in the context of refeeding syndrome, in the absence of hyponatremia. It has also been known to occur in patients suffering withdrawal symptoms of chronic alcoholism. In these instances, occurrence may be entirely unrelated to hyponatremia or rapid correction of hyponatremia. It could affect patients who take some prescription medicines that are able to cross the blood-brain barrier and cause abnormal thirst reception - in this scenario the central pontine myelinolysis is caused by polydipsia leading to low blood sodium levels (hyponatremia). In schizophrenic patients with psychogenic polydipsia, inadequate thirst reception leads to excessive water intake, severely diluting serum sodium. With this excessive thirst combined with psychotic symptoms, brain damage such as central pontine myelinolysis may result from hyperosmolarity caused by excess intake of fluids, (primary polydipsia) although this is difficult to determine because such patients are often institutionalised and have a long history of mental health conditions. It has been observed following hematopoietic stem cell transplantation. Central pontine myelinolysis may also occur in patients prone to hyponatremia affected by: Severe liver disease (e.g., cirrhosis) Liver transplant Alcoholism Hypokalemia People with serum sodium <105 mEq/L Severe burns Malnutrition Anorexia nervosa Severe electrolyte disorders HIV/AIDS hyperemesis gravidarum Hyponatremia due to peritoneal dialysis Wernicke encephalopathy Pathophysiology The currently accepted theory states that the brain cells adjust their osmolarities by changing levels of certain osmolytes like inositol, betaine, and glutamine in response to varying serum osmolality. In the context of chronic low plasma sodium (hyponatremia), the brain compensates by decreasing the levels of these osmolytes within the cells, so that they can remain relatively isotonic with their surroundings and not absorb too much fluid. The reverse is true in hypernatremia, in which the cells increase their intracellular osmolytes so as not to lose too much fluid to the extracellular space. With correction of the hyponatremia with intravenous fluids, the extracellular tonicity increases, followed by an increase in intracellular tonicity. When the correction is too rapid, not enough time is allowed for the brain's cells to adjust to the new tonicity, namely by increasing the intracellular osmoles mentioned earlier. If the serum sodium levels rise too rapidly, the increased extracellular tonicity will continue to drive water out of the brain's cells. This can lead to cellular dysfunction and central pontine myelinolysis. Diagnosis It can be diagnosed clinically in the appropriate context, but may be difficult to confirm radiologically using conventional imaging techniques. Changes are more prominent on MRI than on CT, but often take days | differentiate this condition from multiple sclerosis and other neuroinflammatory disorders. Since this original description, demyelination in other areas of the central nervous system associated with osmotic stress has been described outside the pons (extrapontine). Osmotic demyelination syndrome is the term used for both central pontine myelinolysis and extrapontine myelinolysis. Central pontine myelinolysis, and osmotic demyelination syndrome, present most commonly as a complication of treatment of patients with profound hyponatremia (low sodium), which can result from a varied spectrum of conditions, based on different mechanisms. It occurs as a consequence of a rapid rise in serum tonicity following treatment in individuals with chronic, severe hyponatremia who have made intracellular adaptations to the prevailing hypotonicity. Signs and symptoms Symptoms depend on the regions of the brain involved. Prior to its onset, patients may present with the neurological signs and symptoms of hyponatraemic encephalopathy such as nausea and vomiting, confusion, headache and seizures. These symptoms may resolve with normalisation of the serum sodium concentration. Three to five days later, a second phase of neurological manifestations occurs correlating with the onset of myelinolysis. Observable immediate precursors may include seizures, disturbed consciousness, gait changes, and decrease or cessation of respiratory function.

the crystal structure is perfectly ordered on either side. The analogy with a stack of paper is apt: if a half a piece of paper is inserted in a stack of paper, the defect in the stack is only noticeable at the edge of the half sheet. The screw dislocation is more difficult to visualise, but basically comprises a structure in which a helical path is traced around the linear defect (dislocation line) by the atomic planes of atoms in the crystal lattice. The presence of dislocation results in lattice strain (distortion). The direction and magnitude of such distortion is expressed in terms of a Burgers vector (b). For an edge type, b is perpendicular to the dislocation line, whereas in the cases of the screw type it is parallel. In metallic materials, b is aligned with close-packed crystallographic directions and its magnitude is equivalent to one interatomic spacing. Dislocations can move if the atoms from one of the surrounding planes break their bonds and rebond with the atoms at the terminating edge. It is the presence of dislocations and their ability to readily move (and interact) under the influence of stresses induced by external loads that leads to the characteristic malleability of metallic materials. Dislocations can be observed using transmission electron microscopy, field ion microscopy and atom probe techniques. Deep-level transient spectroscopy has been used for studying the electrical activity of dislocations in semiconductors, mainly silicon. Disclinations are line defects corresponding to "adding" or "subtracting" an angle around a line. Basically, this means that if you track the crystal orientation around the line defect, you get a rotation. Usually, they were thought to play a role only in liquid crystals, but recent developments suggest that they might have a role also in solid materials, e.g. leading to the self-healing of cracks. Planar defects Grain boundaries occur where the crystallographic direction of the lattice abruptly changes. This usually occurs when two crystals begin growing separately and then meet. Antiphase boundaries occur in ordered alloys: in this case, the crystallographic direction remains the same, but each side of the boundary has an opposite phase: For example, if the ordering is usually ABABABAB (hexagonal close-packed crystal), an antiphase boundary takes the form of ABABBABA. Stacking faults occur in a number of crystal structures, but the common example is in close-packed structures. They are formed by a local deviation of the stacking sequence of layers in a crystal. An example would be the ABABCABAB stacking sequence. A twin boundary is a defect that introduces a plane of mirror symmetry in the ordering of a crystal. For example, in cubic close-packed crystals, the stacking sequence of a twin boundary would be ABCABCBACBA. On planes | off-center ions. There are two different types of substitutional defects: Isovalent substitution and aliovalent substitution. Isovalent substitution is where the ion that is substituting the original ion is of the same oxidation state as the ion it is replacing. Aliovalent substitution is where the ion that is substituting the original ion is of a different oxidation state than the ion it is replacing. Aliovalent substitutions change the overall charge within the ionic compound, but the ionic compound must be neutral. Therefore, a charge compensation mechanism is required. Hence either one of the metals is partially or fully oxidised or reduced, or ion vacancies are created. Antisite defects occur in an ordered alloy or compound when atoms of different type exchange positions. For example, some alloys have a regular structure in which every other atom is a different species; for illustration assume that type A atoms sit on the corners of a cubic lattice, and type B atoms sit in the center of the cubes. If one cube has an A atom at its center, the atom is on a site usually occupied by a B atom, and is thus an antisite defect. This is neither a vacancy nor an interstitial, nor an impurity. Topological defects are regions in a crystal where the normal chemical bonding environment is topologically different from the surroundings. For instance, in a perfect sheet of graphite (graphene) all atoms are in rings containing six atoms. If the sheet contains regions where the number of atoms in a ring is different from six, while the total number of atoms remains the same, a topological defect has formed. An example is the Stone Wales defect in nanotubes, which consists of two adjacent 5-membered and two 7-membered atom rings. Also amorphous solids may contain defects. These are naturally somewhat hard to define, but sometimes their nature can be quite easily understood. For instance, in ideally bonded amorphous silica all Si atoms have 4 bonds to O atoms and all O atoms have 2 bonds to Si atom. Thus e.g. an O atom with only one Si bond (a dangling bond) can be considered a defect in silica. Moreover, defects can also be defined in amorphous solids based on empty or densely packed local atomic neighbourhoods, and the properties of such 'defects' can be shown to be similar to normal vacancies and interstitials in crystals. Complexes can form between different kinds of point defects. For example, if a vacancy encounters an impurity, the two may bind together if the impurity is too large for the lattice. Interstitials can form 'split interstitial' or 'dumbbell' structures where two atoms effectively share an atomic site, resulting in neither atom actually occupying the site. Line defects Line defects can be described by gauge theories. Dislocations are linear defects, around which the atoms of the crystal lattice are misaligned. There are two basic types of dislocations, the edge dislocation and the screw dislocation. "Mixed" dislocations, combining aspects of both types, are also common. Edge dislocations are caused by the termination of a plane of atoms in the middle of a crystal. In such a case, the adjacent planes are not straight, but instead bend around the edge of the terminating plane so that the crystal structure is perfectly ordered on either side. The analogy with a stack of paper is apt: if a half a piece of paper is inserted in a stack of paper, the defect in the stack is only noticeable at the edge of the half sheet. The screw dislocation is more difficult to visualise, but basically comprises a structure in which a helical path is traced around the linear defect (dislocation line) by the atomic planes of atoms in the crystal lattice. The presence of dislocation results in lattice strain (distortion). The direction and magnitude of such distortion is expressed in terms of a Burgers vector (b). For an edge type, b is perpendicular to the dislocation line, whereas in the cases of the screw type it is parallel. In metallic materials, b is aligned with close-packed crystallographic directions and its magnitude is equivalent to one interatomic spacing. Dislocations can move if the atoms from one of the surrounding planes break their bonds and rebond with the atoms at the terminating edge. It is the presence of dislocations and their ability to readily move (and interact) under the influence of stresses induced by external loads that leads to the characteristic malleability of metallic materials. Dislocations can be observed using transmission electron microscopy, field ion microscopy and atom probe techniques. Deep-level transient spectroscopy has been used for studying the electrical activity of dislocations in semiconductors, mainly silicon. Disclinations are line defects corresponding to "adding" or "subtracting" an angle around a line. Basically, this means that if you track the crystal orientation around the line defect, you get a rotation. Usually, they were thought to play a role only in |
produced by the context-free grammar G. Every grammar in Chomsky normal form is context-free, and conversely, every context-free grammar can be transformed into an equivalent one which is in Chomsky normal form and has a size no larger than the square of the original grammar's size. Converting a grammar to Chomsky normal form To convert a grammar to Chomsky normal form, a sequence of simple transformations is applied in a certain order; this is described in most textbooks on automata theory. The presentation here follows Hopcroft, Ullman (1979), but is adapted to use the transformation names from Lange, Leiß (2009). Each of the following transformations establishes one of the properties required for Chomsky normal form. START: Eliminate the start symbol from right-hand sides Introduce a new start symbol S0, and a new rule S0 → S, where S is the previous start symbol. This does not change the grammar's produced language, and S0 will not occur on any rule's right-hand side. TERM: Eliminate rules with nonsolitary terminals To eliminate each rule A → X1 ... a ... Xn with a terminal symbol a being not the only symbol on the right-hand side, introduce, for every such terminal, a new nonterminal symbol Na, and a new rule Na → a. Change every rule A → X1 ... a ... Xn to A → X1 ... Na ... Xn. If several terminal symbols occur on the right-hand side, simultaneously replace each of them by its associated nonterminal symbol. This does not change the grammar's produced language. BIN: Eliminate right-hand sides with more than 2 nonterminals Replace each rule A → X1 X2 ... Xn with more than 2 nonterminals X1,...,Xn by rules A → X1 A1, A1 → X2 A2, ... , An-2 → Xn-1 Xn, where Ai are new nonterminal symbols. Again, this does not change the grammar's produced language. DEL: Eliminate ε-rules An ε-rule is a rule of the form A → ε, where A is not S0, the grammar's start symbol. To eliminate all rules of this form, first determine the set of all nonterminals that derive ε. Hopcroft and Ullman (1979) call such nonterminals nullable, and compute them as follows: If a rule A → ε exists, then A is nullable. If a rule A → X1 ... Xn exists, and every single Xi is nullable, then A is nullable, too. Obtain an intermediate grammar by replacing each rule A → X1 ... Xn by all versions with some nullable Xi omitted. By deleting in this grammar each ε-rule, unless its left-hand side is the start symbol, the transformed grammar is obtained. For example, in the following grammar, with start symbol S0, S0 → AbB | C B → AA | AC C → b | c A → a | ε the nonterminal A, and hence also B, is nullable, while neither C nor S0 is. Hence the following intermediate grammar is obtained: S0 → b | b | b | b | C B → | | | ε | C | C C → b | c A → a | ε In this grammar, all ε-rules have been "inlined at the call site". In the next step, they can hence be deleted, yielding the grammar: S0 → AbB | Ab | bB | b | C B → AA | A | AC | C C → b | c A → a This grammar produces the same language as the original example grammar, viz. {ab,aba,abaa,abab,abac,abb,abc,b,bab,bac,bb,bc,c}, but has no ε-rules. UNIT: Eliminate unit rules A unit rule is a rule of the form A → B, where A, B are nonterminal symbols. To remove it, for each rule B → X1 ... Xn, where X1 ... Xn is a string of nonterminals and terminals, add rule A → X1 ... Xn unless this is a unit rule which has already been (or is being) removed. Order of transformations When choosing the order in which the above transformations are to be applied, it has to be considered that some transformations may destroy the result achieved by other ones. For example, START will re-introduce a unit | right-hand sides Introduce a new start symbol S0, and a new rule S0 → S, where S is the previous start symbol. This does not change the grammar's produced language, and S0 will not occur on any rule's right-hand side. TERM: Eliminate rules with nonsolitary terminals To eliminate each rule A → X1 ... a ... Xn with a terminal symbol a being not the only symbol on the right-hand side, introduce, for every such terminal, a new nonterminal symbol Na, and a new rule Na → a. Change every rule A → X1 ... a ... Xn to A → X1 ... Na ... Xn. If several terminal symbols occur on the right-hand side, simultaneously replace each of them by its associated nonterminal symbol. This does not change the grammar's produced language. BIN: Eliminate right-hand sides with more than 2 nonterminals Replace each rule A → X1 X2 ... Xn with more than 2 nonterminals X1,...,Xn by rules A → X1 A1, A1 → X2 A2, ... , An-2 → Xn-1 Xn, where Ai are new nonterminal symbols. Again, this does not change the grammar's produced language. DEL: Eliminate ε-rules An ε-rule is a rule of the form A → ε, where A is not S0, the grammar's start symbol. To eliminate all rules of this form, first determine the set of all nonterminals that derive ε. Hopcroft and Ullman (1979) call such nonterminals nullable, and compute them as follows: If a rule A → ε exists, then A is nullable. If a rule A → X1 ... Xn exists, and every single Xi is nullable, then A is nullable, too. Obtain an intermediate grammar by replacing each rule A → X1 ... Xn by all versions with some nullable Xi omitted. By deleting in this grammar each ε-rule, unless its left-hand side is the start symbol, the transformed grammar is obtained. For example, in the following grammar, with start symbol S0, S0 → AbB | C B → AA | AC C → b | c A → a | ε the nonterminal A, and hence also B, is nullable, while neither C nor S0 is. Hence the following intermediate grammar is obtained: S0 → b | b | b | b | C B → | | | ε | C | C C → b | c A → a | ε In this grammar, all ε-rules have been "inlined at the call site". In the next step, they can hence be deleted, yielding the grammar: S0 → AbB | Ab | bB | b | C B → AA | A | AC | C C → b | c A → a This grammar produces the same language as the original example grammar, viz. {ab,aba,abaa,abab,abac,abb,abc,b,bab,bac,bb,bc,c}, but has no ε-rules. UNIT: Eliminate unit rules A unit rule is a rule of the form A → B, where A, B are nonterminal symbols. To remove it, for each rule B → X1 ... Xn, where X1 ... Xn is |
ban. These three nuclear powers made notable progress in the late 1970s, agreeing to terms on a ban on all testing, including a temporary prohibition on PNEs, but continued disagreements over the compliance mechanisms led to an end to negotiations ahead of Ronald Reagan's inauguration as president in 1981. In 1985, Soviet leader Mikhail Gorbachev announced a unilateral testing moratorium, and in December 1986, Reagan reaffirmed US commitment to pursue the long-term goal of a comprehensive test ban. In November 1987, negotiations on a test ban restarted, followed by a joint US-Soviet program to research underground-test detection in December 1987. Negotiations Given the political situation prevailing in the subsequent decades, little progress was made in nuclear disarmament until the end of the Cold War in 1991. Parties to the PTBT held an amendment conference that year to discuss a proposal to convert the Treaty into an instrument banning all nuclear-weapon tests. With strong support from the UN General Assembly, negotiations for a comprehensive test-ban treaty began in 1993. Adoption Extensive efforts were made over the next three years to draft the Treaty text and its two annexes. However, the Conference on Disarmament, in which negotiations were being held, did not succeed in reaching consensus on the adoption of the text. Under the direction of Prime Minister John Howard and Foreign Minister Alexander Downer, Australia then sent the text to the United Nations General Assembly in New York, where it was submitted as a draft resolution. On 10 September 1996, the Comprehensive Test-Ban Treaty (CTBT) was adopted by a large majority, exceeding two-thirds of the General Assembly's Membership. Obligations (Article I): Each State Party undertakes not to carry out any nuclear weapon test explosion or any other nuclear explosion, and to prohibit and prevent any such nuclear explosion at any place under its jurisdiction or control. Each State Party undertakes, furthermore, to refrain from causing, encouraging, or in any way participating in the carrying out of any nuclear weapon test explosion or any other nuclear explosion. Status The Treaty was adopted by the United Nations General Assembly on 10 September 1996. It opened for signature in New York on 24 September 1996, when it was signed by 71 States, including five of the eight then nuclear-capable states. As of February 2021, 170 states have ratified the CTBT and another 15 states have signed but not ratified it. The treaty will enter into force 180 days after the 44 states listed in Annex 2 of the treaty have ratified it. These "Annex 2 states" are states that participated in the CTBT's negotiations between 1994 and 1996 and possessed nuclear power reactors or research reactors at that time. As of 2016, eight Annex 2 states have not ratified the treaty: China, Egypt, Iran, Israel and the United States have signed but not ratified the Treaty; India, North Korea and Pakistan have not signed it. Monitoring Geophysical and other technologies are used to monitor for compliance with the Treaty: forensic seismology, hydroacoustics, infrasound, and radionuclide monitoring. The first three forms of monitoring are known as wave-form measurements. Seismic monitoring is performed with a system of 50 primary stations located throughout the world, with 120 auxiliary stations in signatory states. Hydroacoustic monitoring is performed with a system of 11 stations that consist of hydrophone triads to monitor for underwater explosions. Hydroacoustic stations can use seismometers to measure T-waves from possible underwater explosions instead of hydrophones. The best measurement of hydroacoustic waves has been found to be at a depth of 1000 m. Infrasound monitoring relies on changes in atmospheric pressure caused by a possible nuclear explosion, with 41 stations certified as of August 2019. One of the biggest concerns with infrasound measurements is noise due to exposure from wind, which can affect the sensor's ability to measure if an event occurred. Together, these technologies are used to monitor the ground, water, and atmosphere for any sign of a nuclear explosion. Radionuclide monitoring takes the form of either monitoring for radioactive particulates or noble gases as a product of a nuclear explosion. Radioactive particles emit radiation that can be measured by any of the 80 stations located throughout the world. They are created from nuclear explosions that can collect onto the dust that is moved from the explosion. If a nuclear explosion took place underground, noble gas monitoring can be used to verify whether or not a possible nuclear explosion took place. Noble gas monitoring relies on measuring increases in radioactive xenon gas. Different isotopes of xenon include 131mXe, 133Xe, 133mXe, and 135Xe. All four monitoring methods make up the International Monitoring System (IMS). Statistical theories and methods are integral to CTBT monitoring providing confidence in verification | weapons states. In 1974, a step towards a comprehensive test ban was made with the Threshold Test Ban Treaty (TTBT), ratified by the US and Soviet Union, which banned underground tests with yields above 150 kilotons. In April 1976, the two states reached agreement on the Peaceful Nuclear Explosions Treaty (PNET), which concerns nuclear detonations outside the weapons sites discussed in the TTBT. As in the TTBT, the US and Soviet Union agreed to bar peaceful nuclear explosions (PNEs) at these other locations with yields above 150 kilotons, as well as group explosions with total yields over 1,500 kilotons. To verify compliance, the PNET requires that states rely on national technical means of verification, share information on explosions, and grant on-site access to counterparties. The TTBT and PNET entered into force on 11 December 1990. In October 1977, the US, UK, and Soviet Union returned to negotiations over a test ban. These three nuclear powers made notable progress in the late 1970s, agreeing to terms on a ban on all testing, including a temporary prohibition on PNEs, but continued disagreements over the compliance mechanisms led to an end to negotiations ahead of Ronald Reagan's inauguration as president in 1981.

All four monitoring methods make up the International Monitoring System (IMS). Statistical theories and methods are integral to CTBT monitoring providing confidence in verification analysis. Once the Treaty enters into force, on-site inspections will be conducted where concerns about compliance arise. The Preparatory Commission for the Comprehensive Test Ban Treaty Organization (CTBTO), an international organization headquartered in Vienna, Austria, was created to build the verification framework, including establishment and provisional operation of the network of monitoring stations, the creation of an international data centre (IDC), and development of the on-site Inspection capability. The CTBTO is responsible for collecting information from the IMS and distribute the analyzed and raw data to member states to judge whether or not a nuclear explosion occurred through the IDC. Parameters such as determining the location where a nuclear explosion or test took place is one of the things that the IDC can accomplish. If a member state chooses to assert that another state had violated the CTBT, they can request an on-site inspection to take place to verify. The monitoring network consists of 337 facilities located all over the globe. As of May 2012, more than 260 facilities have been certified. The monitoring stations register data that is transmitted to the international data centre in Vienna for processing and analysis. The data are sent to states that have signed the Treaty.

of (or in addition to) music. Many early forms of music and dance were created for each other and are frequently performed together. Notable examples of traditional dance/music couplings include the jig, waltz, tango, disco, and salsa. Some musical genres have a parallel dance form such as baroque music and baroque dance; other varieties of dance and music may share nomenclature but developed separately, such as classical music and classical ballet. The choreography and music go hand in hand, as they complement each other to express a story told by the choreographer and or dancers. Rhythm Rhythm and dance are deeply linked in history and practice. The American dancer Ted Shawn wrote; "The conception of rhythm which underlies all studies of the dance is something about which we could talk forever, and still not finish." A musical rhythm requires two main elements; first, a regularly-repeating pulse (also called the "beat" or "tactus") that establishes the tempo and, second, a pattern of accents and rests that establishes the character of the metre or basic rhythmic pattern. The basic pulse is roughly equal in duration to a simple step or gesture. Dances generally have a characteristic tempo and rhythmic pattern. The tango, for example, is usually danced in time at approximately 66 beats per minute. The basic slow step, called a "slow", lasts for one beat, so that a full "right–left" step is equal to one measure. The basic forward and backward walk of the dance is so counted – "slow-slow" – while many additional figures are counted "slow – quick-quick. Just as musical rhythms are defined by a pattern of strong and weak beats, so repetitive body movements often depend on alternating "strong" and "weak" muscular movements. Given this alternation of left-right, of forward-backward and rise-fall, along with the bilateral symmetry of the human body, it is natural that many dances and much music are in duple and quadruple meter. Since some such movements require more time in one phase than the other – such as the longer time required to lift a hammer than to strike – some dance rhythms fall equally naturally into triple metre. Occasionally, as in the folk dances of the Balkans, dance traditions depend heavily on more complex rhythms. Further, complex dances composed of a fixed sequence of steps always require phrases and melodies of a certain fixed length to accompany that sequence. The very act of dancing, the steps themselves, generate an "initial skeleton of rhythmic beats" that must have preceded any separate musical accompaniment, while dance itself, as much as music, requires time-keeping just as utilitarian repetitive movements such as walking, hauling and digging take on, as they become refined, something of the quality of dance. Musical accompaniment, therefore, arose in the earliest dance, so that ancient Egyptians attributed the origin of the dance to the divine Athotus, who was said to have observed that music accompanying religious rituals caused participants to move rhythmically and to have brought these movements into proportional measure. The same idea, that dance arises from musical rhythm, is still found in renaissance Europe in the works of the dancing master Guglielmo Ebreo da Pesaro who speaks of dance as a physical movement that arises from and expresses inward, spiritual motion agreeing with the "measures and perfect concords of harmony" that fall upon the human ear, while, earlier, Mechthild of Magdeburg, seizing upon dance as a symbol of the holy life foreshadowed in Jesus' saying "I have piped and ye have not danced", writes; Thoinot Arbeau's celebrated 16th-century dance-treatise Orchésographie, indeed, begins with definitions of over eighty distinct drum-rhythms. As has been shown above, dance has been represented through the ages as having emerged as a response to music yet, as Lincoln Kirstein implied, it is at least as likely that primitive music arose from dance. Shawn concurs, stating that dance "was the first art of the human race, and the matrix out of which all other arts grew" and that even the "metre in our poetry today is a result of the accents necessitated by body movement, as the dancing and reciting was performed simultaneously" – an assertion somewhat supported by the common use of the term "foot" to describe the fundamental rhythmic units of poetry. Scholes, not a dancer but a musician, offers support for this view, stating that the steady measures of music, of two, three or four beats to the bar, its equal and balanced phrases, regular cadences, contrasts and repetitions, may all be attributed to the "incalculable" influence of dance upon music. Émile Jaques-Dalcroze, primarily a musician and teacher, relates how a study of the physical movements of pianists led him "to the discovery that musical sensations of a rhythmic nature call for the muscular and nervous response of the whole organism", to develop "a special training designed to regulate nervous reactions and effect a co-ordination of muscles and nerves" and ultimately to seek the connections between "the art of music and the art of dance", which he formulated into his system of eurhythmics. He concluded that "musical rhythm is only the transposition into sound of movements and dynamisms spontaneously and involuntarily expressing emotion". Hence, though doubtless, as Shawn asserts, "it is quite possible to develop the dance without music and... music is perfectly capable of standing on its own feet without any assistance from the dance", nevertheless the "two arts will always be related and the relationship can be profitable both to the dance and to music", the precedence of one art over the other being a moot point. The common ballad measures of hymns and folk-songs takes their name from dance, as does the carol, originally a circle dance. Many purely musical pieces have been named "waltz" or "minuet", for example, while many concert dances have been produced that are based upon abstract musical pieces, such as 2 and 3 Part Inventions, Adams Violin Concerto and Andantino. Similarly, poems are often structured and named after dances or musical works, while dance and music have both drawn their conception of "measure" or "metre" from poetry. Shawn quotes with approval the statement of Dalcroze that, while the art of musical rhythm consists in differentiating and combining time durations, pauses and accents "according to physiological law", that of "plastic rhythm" (i.e. dance) "is to designate movement in space, to interpret long time-values by slow movements and short ones by quick movements, regulate pauses by their divers successions and express sound accentuations in their multiple nuances by additions of bodily weight, by means of muscular innervations". Shawn nevertheless points out that the system of musical time is a "man-made, artificial thing.... a manufactured tool, whereas rhythm is something that has always existed and depends on man not at all", being "the continuous flowing time which our human minds cut up into convenient units", suggesting that music might be revivified by a return to the values and the time-perception of dancing. The early-20th-century American dancer Helen Moller stated simply that "it is rhythm and form more than harmony and color which, from the beginning, has bound music, poetry and dancing together in a union that is indissoluble." Approaches Theatrical Concert dance, like opera, generally depends for its large-scale form upon a narrative dramatic structure. The movements and gestures of the choreography are primarily intended to mime the personality and aims of the characters and their part in the plot. Such theatrical requirements tend towards longer, freer movements than those usual in non-narrative dance styles. On the other hand, the ballet blanc, developed in the 19th century, allows interludes of rhythmic dance that developed into entirely "plotless" ballets in the 20th century and that allowed fast, rhythmic dance-steps such as those of the petit allegro. A well-known example is The Cygnets' Dance in act two of Swan Lake. The ballet developed out of courtly dramatic productions of 16th- and 17th-century France and Italy and for some time dancers performed dances developed from those familiar from the musical suite, all of which were defined by definite rhythms closely identified with each dance. These appeared as character dances in the era of romantic nationalism. Ballet reached widespread vogue in the romantic era, accompanied by a larger orchestra and grander musical conceptions that did not lend themselves easily to rhythmic clarity and by dance that emphasised dramatic mime. A broader concept of rhythm was needed, that which Rudolf Laban terms the "rhythm and shape" of movement that communicates character, emotion and intention, while only certain scenes required the exact synchronisation of step and music essential to other dance styles, so that, to Laban, modern Europeans seemed totally unable to grasp the meaning of "primitive rhythmic movements", a situation that began to change in the 20th century with such productions as Igor Stravinsky's The Rite of Spring with its new rhythmic language evoking primal feelings of a primitive past. Indian classical dance styles, like ballet, are often in dramatic form, so that there is a similar complementarity between narrative expression and "pure" dance. In this case, the two are separately defined, though not always separately performed. The rhythmic elements, which are abstract and technical, are known as nritta. Both this and expressive dance (nritya), though, are closely tied to the rhythmic system (tala). Teachers have adapted the spoken rhythmic mnemonic system called bol to the needs of dancers. Japanese classical dance-theatre styles such as Kabuki and Noh, like Indian dance-drama, distinguish between narrative and abstract dance productions. The three main categories of kabuki are jidaimono (historical), sewamono (domestic) and shosagoto (dance pieces). Somewhat similarly, Noh distinguishes between Geki Noh, based around the advancement of plot and the narration of action, and Furyū Noh, dance pieces involving acrobatics, stage properties, multiple characters and elaborate stage action. Participatory and social Social dances, those intended for participation rather than for an audience, may include various forms of mime and narrative, but are typically set much more closely to the rhythmic pattern of music, so that terms like waltz and polka refer as much to musical pieces as to the dance itself. The rhythm of the dancers' feet may even form an essential part of the music, as in tap dance. African dance, for example, is rooted in fixed basic steps, but may also allow a high degree of rhythmic interpretation: the feet or the trunk mark the basic pulse while cross-rhythms are picked up by shoulders, knees, or head, with the best dancers simultaneously giving plastic expression to all the elements of the polyrhythmic pattern. Cultural traditions Africa Dance in Africa is deeply integrated into society and major events in a community are frequently reflected in dances: dances are performed for births and funerals, weddings and wars. Traditional dances impart cultural morals, including religious traditions and sexual standards; give vent to repressed emotions, such as grief; motivate community members to cooperate, whether fighting wars or grinding grain; enact spiritual rituals; and contribute to social cohesiveness. Thousands of dances are performed around the continent. These may be divided into traditional, neotraditional, and classical styles: folkloric dances of a particular society, dances created more recently in imitation of traditional styles, and dances transmitted more formally in schools or private lessons. African dance has been altered by many forces, such as European missionaries and colonialist governments, who often suppressed local dance traditions as licentious or distracting. Dance in contemporary African cultures still serves its traditional functions in new contexts; dance may celebrate the inauguration of a hospital, build community for rural migrants in unfamiliar cities, and be incorporated into Christian church ceremonies. Asia All Indian classical dances are to varying degrees rooted in the Natyashastra and therefore share common features: for example, the mudras (hand positions), some body positions, leg movement and the inclusion of dramatic or expressive acting or abhinaya. Indian classical music provides accompaniment and dancers of nearly all the styles wear bells around their ankles to counterpoint and complement the percussion. There are now many regional varieties of Indian classical dance. Dances like "Odra Magadhi", which after decades-long debate, has been traced to present day Mithila, Odisha region's dance form of Odissi (Orissi), indicate influence of dances in cultural interactions between different regions. The Punjab area overlapping India and Pakistan is the place of origin of Bhangra. It is widely known both as a style of music and a dance. It is mostly related to ancient harvest celebrations, love, patriotism or social issues. Its music is coordinated by a musical instrument called the 'Dhol'. Bhangra is not just music but a dance, a celebration of the harvest where people beat the dhol (drum), sing Boliyaan (lyrics) and dance. It developed further with the Vaisakhi festival of the Sikhs. The dances of Sri Lanka include the devil dances (yakun natima), a carefully crafted ritual reaching far back into Sri Lanka's pre-Buddhist past that combines ancient "Ayurvedic" concepts of disease causation with psychological manipulation and combines many aspects including Sinhalese cosmology. Their influence can be seen on the classical dances of Sri Lanka. Indonesian dances reflect the richness and diversity of | music, of two, three or four beats to the bar, its equal and balanced phrases, regular cadences, contrasts and repetitions, may all be attributed to the "incalculable" influence of dance upon music. Émile Jaques-Dalcroze, primarily a musician and teacher, relates how a study of the physical movements of pianists led him "to the discovery that musical sensations of a rhythmic nature call for the muscular and nervous response of the whole organism", to develop "a special training designed to regulate nervous reactions and effect a co-ordination of muscles and nerves" and ultimately to seek the connections between "the art of music and the art of dance", which he formulated into his system of eurhythmics. He concluded that "musical rhythm is only the transposition into sound of movements and dynamisms spontaneously and involuntarily expressing emotion". Hence, though doubtless, as Shawn asserts, "it is quite possible to develop the dance without music and... music is perfectly capable of standing on its own feet without any assistance from the dance", nevertheless the "two arts will always be related and the relationship can be profitable both to the dance and to music", the precedence of one art over the other being a moot point. The common ballad measures of hymns and folk-songs takes their name from dance, as does the carol, originally a circle dance. Many purely musical pieces have been named "waltz" or "minuet", for example, while many concert dances have been produced that are based upon abstract musical pieces, such as 2 and 3 Part Inventions, Adams Violin Concerto and Andantino. Similarly, poems are often structured and named after dances or musical works, while dance and music have both drawn their conception of "measure" or "metre" from poetry. Shawn quotes with approval the statement of Dalcroze that, while the art of musical rhythm consists in differentiating and combining time durations, pauses and accents "according to physiological law", that of "plastic rhythm" (i.e. dance) "is to designate movement in space, to interpret long time-values by slow movements and short ones by quick movements, regulate pauses by their divers successions and express sound accentuations in their multiple nuances by additions of bodily weight, by means of muscular innervations". Shawn nevertheless points out that the system of musical time is a "man-made, artificial thing.... a manufactured tool, whereas rhythm is something that has always existed and depends on man not at all", being "the continuous flowing time which our human minds cut up into convenient units", suggesting that music might be revivified by a return to the values and the time-perception of dancing. The early-20th-century American dancer Helen Moller stated simply that "it is rhythm and form more than harmony and color which, from the beginning, has bound music, poetry and dancing together in a union that is indissoluble." Approaches Theatrical Concert dance, like opera, generally depends for its large-scale form upon a narrative dramatic structure. The movements and gestures of the choreography are primarily intended to mime the personality and aims of the characters and their part in the plot. Such theatrical requirements tend towards longer, freer movements than those usual in non-narrative dance styles. On the other hand, the ballet blanc, developed in the 19th century, allows interludes of rhythmic dance that developed into entirely "plotless" ballets in the 20th century and that allowed fast, rhythmic dance-steps such as those of the petit allegro. A well-known example is The Cygnets' Dance in act two of Swan Lake. The ballet developed out of courtly dramatic productions of 16th- and 17th-century France and Italy and for some time dancers performed dances developed from those familiar from the musical suite, all of which were defined by definite rhythms closely identified with each dance. These appeared as character dances in the era of romantic nationalism. Ballet reached widespread vogue in the romantic era, accompanied by a larger orchestra and grander musical conceptions that did not lend themselves easily to rhythmic clarity and by dance that emphasised dramatic mime. A broader concept of rhythm was needed, that which Rudolf Laban terms the "rhythm and shape" of movement that communicates character, emotion and intention, while only certain scenes required the exact synchronisation of step and music essential to other dance styles, so that, to Laban, modern Europeans seemed totally unable to grasp the meaning of "primitive rhythmic movements", a situation that began to change in the 20th century with such productions as Igor Stravinsky's The Rite of Spring with its new rhythmic language evoking primal feelings of a primitive past. Indian classical dance styles, like ballet, are often in dramatic form, so that there is a similar complementarity between narrative expression and "pure" dance. In this case, the two are separately defined, though not always separately performed. The rhythmic elements, which are abstract and technical, are known as nritta. Both this and expressive dance (nritya), though, are closely tied to the rhythmic system (tala). Teachers have adapted the spoken rhythmic mnemonic system called bol to the needs of dancers. Japanese classical dance-theatre styles such as Kabuki and Noh, like Indian dance-drama, distinguish between narrative and abstract dance productions. The three main categories of kabuki are jidaimono (historical), sewamono (domestic) and shosagoto (dance pieces). Somewhat similarly, Noh distinguishes between Geki Noh, based around the advancement of plot and the narration of action, and Furyū Noh, dance pieces involving acrobatics, stage properties, multiple characters and elaborate stage action. Participatory and social Social dances, those intended for participation rather than for an audience, may include various forms of mime and narrative, but are typically set much more closely to the rhythmic pattern of music, so that terms like waltz and polka refer as much to musical pieces as to the dance itself. The rhythm of the dancers' feet may even form an essential part of the music, as in tap dance. African dance, for example, is rooted in fixed basic steps, but may also allow a high degree of rhythmic interpretation: the feet or the trunk mark the basic pulse while cross-rhythms are picked up by shoulders, knees, or head, with the best dancers simultaneously giving plastic expression to all the elements of the polyrhythmic pattern. Cultural traditions Africa Dance in Africa is deeply integrated into society and major events in a community are frequently reflected in dances: dances are performed for births and funerals, weddings and wars. Traditional dances impart cultural morals, including religious traditions and sexual standards; give vent to repressed emotions, such as grief; motivate community members to cooperate, whether fighting wars or grinding grain; enact spiritual rituals; and contribute to social cohesiveness. Thousands of dances are performed around the continent. These may be divided into traditional, neotraditional, and classical styles: folkloric dances of a particular society, dances created more recently in imitation of traditional styles, and dances transmitted more formally in schools or private lessons. African dance has been altered by many forces, such as European missionaries and colonialist governments, who often suppressed local dance traditions as licentious or distracting. Dance in contemporary African cultures still serves its traditional functions in new contexts; dance may celebrate the inauguration of a hospital, build community for rural migrants in unfamiliar cities, and be incorporated into Christian church ceremonies. Asia All Indian classical dances are to varying degrees rooted in the Natyashastra and therefore share common features: for example, the mudras (hand positions), some body positions, leg movement and the inclusion of dramatic or expressive acting or abhinaya. Indian classical music provides accompaniment and dancers of nearly all the styles wear bells around their ankles to counterpoint and complement the percussion. There are now many regional varieties of Indian classical dance. Dances like "Odra Magadhi", which after decades-long debate, has been traced to present day Mithila, Odisha region's dance form of Odissi (Orissi), indicate influence of dances in cultural interactions between different regions. The Punjab area overlapping India and Pakistan is the place of origin of Bhangra. It is widely known both as a style of music and a dance. It is mostly related to ancient harvest celebrations, love, patriotism or social issues. Its music is coordinated by a musical instrument called the 'Dhol'. Bhangra is not just music but a dance, a celebration of the harvest where people beat the dhol (drum), sing Boliyaan (lyrics) and dance. It developed further with the Vaisakhi festival of the Sikhs. The dances of Sri Lanka include the devil dances (yakun natima), a carefully crafted ritual reaching far back into Sri Lanka's pre-Buddhist past that combines ancient "Ayurvedic" concepts of disease causation with psychological manipulation and combines many aspects including Sinhalese cosmology. Their influence can be seen on the classical dances of Sri Lanka. Indonesian dances reflect the richness and diversity of Indonesian ethnic groups and cultures. There are more than 1,300 ethnic groups in Indonesia, it can be seen from the cultural roots of the Austronesian and Melanesian peoples, and various cultural influences from Asia and the west. Dances in Indonesia originate from ritual movements and religious ceremonies, this kind of dance usually begins with rituals, such as war dances, shaman dances to cure or ward off disease, dances to call rain and other types of dances. With the acceptance of dharma religion in the 1st century in Indonesia, Hinduism and Buddhist rituals were celebrated in various artistic performances. Hindu epics such as the Ramayana, Mahabharata and also the Panji became the inspiration to be shown in a dance-drama called "Sendratari" resembling "ballet" in the western tradition. An elaborate and highly stylized dance method was invented and has survived to this day, especially on the islands of Java and Bali. The Javanese Wayang wong dance takes footage from the Ramayana or Mahabharata episodes, but this dance is very different from the Indian version, indonesian dances do not pay as much attention to the "mudras" as Indian dances: even more to show local forms. The sacred Javanese ritual dance Bedhaya is believed to date back to the Majapahit period in the 14th century or even earlier, this dance originated from ritual dances performed by virgin girls to worship Hindu Gods such as Shiva, Brahma, and Vishnu. In Bali, dance has become an integral part of the sacred Hindu Dharma rituals. Some experts believe that Balinese dance comes from an older dance tradition from Java. Reliefs from temples in East Java from the 14th century feature crowns and headdresses similar to the headdresses used in Balinese dance today. Islam began to spread to the Indonesian archipelago when indigenous dances and dharma dances were still popular. Artists and dancers still use styles from the previous era, replacing stories with more Islamic interpretations and clothing that is more closed according to Islamic teachings. The dances of the Middle East are usually the traditional forms of circle dancing which are modernized to an extent. They would include dabke, tamzara, Assyrian folk dance, Kurdish dance, Armenian dance and Turkish dance, among others. All these forms of dances would usually involve participants engaging each other by holding hands or arms (depending on the style of the dance). They would make rhythmic moves with their legs and shoulders as they curve around the dance floor. The head of the dance would generally hold a cane or handkerchief. Europe and North America Folk dances vary across Europe and may date back hundreds or thousands of years, but many have features in common such as group participation led by a caller, hand-holding or arm-linking between participants, and fixed musical forms known as caroles. Some, such as the maypole dance are common to many nations, while others such as the céilidh and the polka are deeply-rooted in a single culture. Some European folk dances such as the square dance were brought to the New World and subsequently became part of American culture. Ballet developed first in Italy and then in France from lavish court spectacles that combined music, drama, poetry, song, costumes and dance. Members of the court nobility took part as performers. During the reign of Louis XIV, himself a dancer, dance became more codified. Professional dancers began to take the place of court amateurs, and ballet masters were licensed by the French government. The first ballet dance academy was the Académie Royale de Danse (Royal Dance Academy), opened in Paris in 1661. Shortly thereafter, the first institutionalized ballet troupe, associated with the Academy, was formed; this troupe began as an all-male ensemble but by 1681 opened to include women as well. 20th century concert dance brought an explosion of innovation in dance style characterized by |

Pickford, and Douglas Fairbanks; the studio was premised on allowing actors to control their own interests rather than being dependent upon commercial studios. He continued to make films, but never again achieved box-office grosses as high as either The Birth of a Nation or Intolerance. Later film career Though United Artists survived as a company, Griffith's association with it was short-lived. While some of his later films did well at the box office, commercial success often eluded him. Griffith features from this period include Broken Blossoms (1919), Way Down East (1920), Orphans of the Storm (1921), Dream Street (1921), One Exciting Night (1922) and America (1924). Of these, the first three were successes at the box office. Griffith was forced to leave United Artists after Isn't Life Wonderful (1924) failed at the box office. He made a part-talkie, Lady of the Pavements (1929), and only two full-sound films: Abraham Lincoln (1930) and The Struggle (1931). Neither was successful, and after The Struggle he never made another film. In 1936, director Woody Van Dyke, who had worked as Griffith's apprentice on Intolerance, asked Griffith to help him shoot the famous earthquake sequence for San Francisco, but did not give him any film credit. Starring Clark Gable, Jeanette MacDonald and Spencer Tracy, it was the top-grossing film of the year. In 1939, the producer Hal Roach hired Griffith to produce Of Mice and Men (1939) and One Million B.C. (1940). He wrote to Griffith: "I need help from the production side to select the proper writers, cast, et cetera, and to help me generally in the supervision of these pictures." Although Griffith eventually disagreed with Roach over the production and parted, Roach later insisted that some of the scenes in the completed film were directed by Griffith. This would make the film the final production in which Griffith was actively involved. However, cast members' accounts recall Griffith directing only the screen tests and costume tests. When Roach advertised the film in late 1939 with Griffith listed as producer, the latter asked that his name be removed. Griffith was for decades held in awe by many members of the film industry. He was presented a special Oscar by the Academy of Motion Picture Arts and Sciences in the mid-1930s. In 1946, he made an impromptu visit to the film location of David O. Selznick's epic western Duel in the Sun, where some of his veteran actors—Lillian Gish, Lionel Barrymore and Harry Carey—were cast members. Gish and Barrymore found their old mentor's presence distracting and became self-conscious; in response, Griffith hid behind the scenery when the two were filming their scenes. Death On the morning of July 23, 1948, Griffith was discovered unconscious in the lobby at the Knickerbocker Hotel in Los Angeles, where he had been living alone. He died of a cerebral hemorrhage at 3:42 PM on the way to a Hollywood hospital. A public memorial service was held in his honor at the Hollywood Masonic Temple. He is buried at Mount Tabor Methodist Church Graveyard in Centerfield, Kentucky. In 1950, The Directors Guild of America provided a stone and bronze monument for his grave site. Legacy Performer and director Charlie Chaplin called Griffith "The Teacher of Us All". Filmmakers such as Alfred Hitchcock, Lev Kuleshov, Jean Renoir, Cecil B. DeMille, King Vidor, Victor Fleming, Raoul Walsh, Carl Theodor Dreyer, Sergei Eisenstein, and Stanley Kubrick have praised Griffith. Griffith seems to have been the first to understand how certain film techniques could be used to create an expressive language; it gained popular recognition with the release of his The Birth of a Nation (1915). His early shorts —such as Biograph's The Musketeers of Pig Alley (1912), show that Griffith's attention to camera placement and lighting heightened mood and tension. In making Intolerance Griffith opened up new possibilities for the medium, creating a form that seems to owe more to music than to traditional narrative. In the 1951 Philco Television Playhouse episode "The Birth of the Movies" events from Griffith's film career were depicted. Griffith was played by John Newland. In 1953 the Directors Guild of America (DGA) instituted the D. W. Griffith Award, its highest honor. However, on December 15, 1999, then DGA President Jack Shea and the DGA National Board announced that the award would be renamed as the "DGA Lifetime Achievement Award". They stated that, although Griffith was extremely talented, they felt his film The Birth of a Nation had "helped foster intolerable racial stereotypes", and that it was thus better not to have the top award in his name. In 1975 Griffith was honored on a ten-cent postage stamp by the United States. The 1976 American comedy film Nickelodeon in part pays homage to silent film makers and includes footage from The Birth of a Nation. D. W. Griffith Middle School in Los Angeles is named after Griffith. Because of the association of Griffith and the racist nature of The Birth of a Nation, attempts have been made to rename the 99% minority-enrolled school. In 2008 the Hollywood Heritage Museum hosted a screening of Griffith's earliest films to commemorate the centennial of his start in film. On January 22, 2009, the Oldham History Center in La Grange, Kentucky opened a 15-seat theatre in Griffith's honor. The theatre features a library of available Griffith films. Film preservation Griffith has six films preserved on the United States National Film Registry deemed as being "culturally, historically, or aesthetically significant". These are Lady Helen's Escapade (1909), A Corner in Wheat (1909), The Musketeers of Pig Alley (1912), The Birth of a Nation (1915), Intolerance (1916) and Broken Blossoms (1919). See also D. W.

There he co-produced The Life of General Villa, a silent biographical-action movie starring Pancho Villa as himself, shot on location in Mexico during a civil war. He formed a studio with Majestic Studios manager Harry Aitken, which became known as Reliance-Majestic Studios and later was renamed Fine Arts Studios. His new production company became an autonomous production unit partner in the Triangle Film Corporation along with Thomas H. Ince and Keystone Studios' Mack Sennett. The Triangle Film Corporation was headed by Aitken, who was released from the Mutual Film Corporation, and his brother Roy. Griffith directed and produced The Clansman through Reliance-Majestic Studios in 1915, which became known as The Birth of a Nation and is considered one of the early feature length American films. The film was a success, but it aroused much controversy due to its depiction of slavery, the Ku Klux Klan and race relations in the American Civil War and the reconstruction era of the United States. It was based on Thomas Dixon Jr.'s 1905 novel The Clansman: A Historical Romance of the Ku Klux Klan; it depicts Southern slavery as benign, the enfranchisement of freedmen as a corrupt plot by the Republican Party, and the Ku Klux Klan as a band of heroes restoring the rightful order. This view of the era was popular at the time and was endorsed for decades by historians of the Dunning School, although it met with strong criticism from the National Association for the Advancement of Colored People (NAACP) and other groups. The NAACP attempted to stop showings of the film. This was successful in some cities, but nonetheless it was shown widely and became the most successful box-office attraction of its time. It is considered among the first "blockbuster" motion pictures, and broke all box office records that had been established until then. "They lost track of the money it made", Lillian Gish remarked in a Kevin Brownlow interview. Audiences in some major northern cities rioted over the film's racial content, which was filled with action and violence. Griffith's indignation at efforts to censor or ban the film motivated him to produce Intolerance the following year, in which he portrayed the effects of intolerance in four different historical periods: the Fall of Babylon; the Crucifixion of Jesus; the events surrounding the St. Bartholomew's Day massacre (during religious persecution of French Huguenots); and a modern story. Intolerance was not a financial success; it did not bring in enough profits to cover the lavish road show that accompanied it. Griffith put a huge budget into the film's production that could not be recovered in its box office. He mostly financed Intolerance himself, contributing to his financial ruin for the rest of his life. Griffith's production partnership was dissolved in 1917, and he went to Artcraft, part of Paramount Pictures, and then to First National Pictures (1919–1920). At the same time, he founded United Artists together with Charlie Chaplin, Mary Pickford, and Douglas Fairbanks; the studio was premised on allowing actors to control their own interests rather than being dependent upon commercial studios. He continued to make films, but never again achieved box-office grosses as high as either The Birth of a Nation or Intolerance. Later film career Though United Artists survived as a company, Griffith's association with it was short-lived. While some of his later films did well at the box office, commercial success often eluded him. Griffith features from this period include Broken Blossoms (1919), Way Down East (1920), Orphans of the Storm (1921), Dream Street (1921), One Exciting Night (1922) and America (1924). Of these, the first three were successes at the box office. Griffith was forced to leave United Artists after Isn't Life Wonderful (1924) failed at the box office. He made a part-talkie, Lady of the Pavements (1929), and only two full-sound films: Abraham Lincoln (1930) and The Struggle (1931). Neither was successful, and after The Struggle he never made another film. In 1936, director Woody Van Dyke, who had worked as Griffith's apprentice on Intolerance, asked Griffith to help him shoot the famous earthquake sequence for San Francisco, but did not give him any film credit. Starring Clark Gable, Jeanette MacDonald and Spencer Tracy, it was the top-grossing film of the year. In 1939, the producer Hal Roach hired Griffith to produce Of Mice and Men (1939) and One Million B.C. (1940). He wrote to Griffith: "I need help from the production side to select the proper writers, cast, et cetera, and to help me generally in the supervision of these pictures." Although Griffith eventually disagreed with Roach over the production and parted, Roach later insisted that some of the scenes in the completed film were directed by Griffith. This would make the film the final production in which Griffith was actively involved. However, cast members' accounts recall Griffith directing only the screen tests and costume tests. When Roach advertised the film in late 1939 with Griffith listed as producer, the latter asked that his name be removed. Griffith was for decades held in awe by many members of the film industry. He was presented a special Oscar by the Academy of Motion Picture Arts and Sciences in the mid-1930s. In 1946, he made an impromptu visit to the film location of David O. Selznick's epic western Duel in the Sun, where some of his veteran actors—Lillian Gish, Lionel Barrymore and Harry Carey—were cast members. Gish and Barrymore found their old mentor's presence distracting and became self-conscious; in response, Griffith hid behind the scenery when the two were filming their scenes. Death On the morning of July 23, 1948, Griffith was discovered unconscious in the lobby at the Knickerbocker Hotel in Los Angeles, where he had been living alone. He died of a cerebral hemorrhage at 3:42 PM on the way to a Hollywood hospital. A public memorial service was held in his honor at the Hollywood Masonic Temple. He is buried at Mount Tabor Methodist Church Graveyard in Centerfield, Kentucky. In 1950, The Directors Guild of America provided a stone and bronze monument for his grave site.

closed arid basins that retain the highly soluble gypsum that would otherwise be washed into the sea. Nabkha dunes A nabkha, or coppice dune, is a small dune anchored by vegetation. They usually indicate desertification or soil erosion, and serve as nesting and burrow sites for animals. Sub-aqueous dunes Sub-aqueous (underwater) dunes form on a bed of sand or gravel under the actions of water flow. They are ubiquitous in natural channels such as rivers and estuaries, and also form in engineered canals and pipelines. Dunes move downstream as the upstream slope is eroded and the sediment deposited on the downstream or lee slope in typical bedform construction. In the case of sub-aqueous barchan dunes, sediment is lost by their extremities, known as horns. These dunes most often form as a continuous 'train' of dunes, showing remarkable similarity in wavelength and height. The shape of a dune gives information about its formation environment. For instance, rivers produce asymmetrical ripples, with the steeper slip face facing downstream. Ripple marks preserved in sedimentary strata in the geological record can be used to determine the direction of current flow, and thus an indication of the source of the sediments. Dunes on the bed of a channel significantly increase flow resistance, their presence and growth playing a major part in river flooding. Lithified dunes A lithified (consolidated) sand dune is a type of sandstone that is formed when a marine or aeolian sand dune becomes compacted and hardened. Once in this form, water passing through the rock can carry and deposit minerals, which can alter the color of the rock. Cross-bedded layers of stacks of lithified dunes can produce the cross-hatching patterns, such as those seen in Zion National Park in the western United States. A slang term, used in the southwest US, for consolidated and hardened sand dunes is "slickrock", a name that was introduced by pioneers of the Old West because their steel-rimmed wagon wheels could not gain traction on the rock. Desertification Sand dunes can have a negative impact on humans when they encroach on human habitats. Sand dunes move via a few different means, all of them helped along by wind. One way that dunes can move is by saltation, where sand particles skip along the ground like a bouncing ball. When these skipping particles land, they may knock into other particles and cause them to move as well, in a process known as creep. With slightly stronger winds, particles collide in mid-air, causing sheet flows. In a major dust storm, dunes may move tens of metres through such sheet flows. Also as in the case of snow, sand avalanches, falling down the slipface of the dunes—that face away from the winds—also move the dunes forward. Sand threatens buildings and crops in Africa, the Middle East, and China. Drenching sand dunes with oil stops their migration, but this approach uses a valuable resource and is quite destructive to the dunes' animal habitats. Sand fences might also slow their movement to a crawl, but geologists are still analyzing results for the optimum fence designs. Preventing sand dunes from overwhelming towns, villages, and agricultural areas has become a priority for the United Nations Environment Programme. Planting dunes with vegetation also helps to stabilise them. Conservation Dune habitats provide niches for highly specialized plants and animals, including numerous rare species and some endangered species. Due to widespread human population expansion, dunes face destruction through land development and recreational usages, as well as alteration to prevent the encroachment of sand onto inhabited areas. Some countries, notably the United States, Australia, Canada, New Zealand, the United Kingdom, Netherlands, and Sri Lanka have developed significant programs of dune protection through the use of sand dune stabilization. In the U.K., a Biodiversity Action Plan has been developed to assess dunes loss and to prevent future dunes destruction.

Indiana Dunes | snakes, lizards, and rodents can live in coastal sand dunes, along with insects of all types. Often the vegetation of sand dunes is discussed without acknowledging the importance that coastal dunes have for animals. Further, some animals, such as foxes and feral pigs can use coastal dunes as hunting grounds to find food. Birds are also known to utilize coastal dunes as nesting grounds. All these species find the coastal environment of the sand dune vital to their species' survival. Over the course of time coastal dunes may be impacted by tropical cyclones or other intense storm activity, dependent on their location. Recent work has suggested that coastal dunes tend to evolve toward a high or low morphology depending on the growth rate of dunes relative to storm frequency. During a storm event, dunes play a significant role in minimizing wave energy as it moves onshore. As a result, coastal dunes, especially those in the foredune area affected by a storm surge, will retreat or erode. To counteract the damage from tropical activity on coastal dunes, short term post-storm efforts can be made by individual agencies through fencing to help with sand accumulation. How much a dune erodes during any storm surge is related to its location on the coastal shoreline and the profile of the beach during a particular season. In those areas with harsher winter weather, during the summer a beach tends to take on more of a convex appearance due to gentler waves, while the same beach in the winter may take on more of a concave appearance. As a result, coastal dunes can get eroded much more quickly in the winter than in the summer. The converse is true in areas with harsher summer weather. There are many threats to these coastal communities. Some coastal dunes, for example ones in San Francisco, have been completely altered by urbanization; reshaping the dune for human use. This puts native species at risk. Another danger, in California and places in the UK specifically, is the introduction of invasive species. Plant species, such as Carpobrotus edulis, were introduced from South Africa in an attempt to stabilize the dunes and provide horticultural benefits, but instead spread taking land away from native species. Ammophila arenaria, known as European beachgrass, has a similar story, though it has no horticulture benefits. It has great ground coverage and, as intended, stabilized the dunes but as an unintended side effect prevented native species from thriving in those dunes. One such example is the dune field at Point Reyes, California. There are now efforts to get rid of both of these invasive species. Ecological succession on coastal dunes As a dune forms, plant succession occurs. The conditions on an embryo dune are harsh, with salt spray from the sea carried on strong winds. The dune is well drained and often dry, and composed of calcium carbonate from seashells. Rotting seaweed, brought in by storm waves adds nutrients to allow pioneer species to colonize the dune. For example, in the United Kingdom these pioneer species are often marram grass, sea wort grass and other sea grasses. These plants are well adapted to the harsh conditions of the foredune, typically having deep roots which reach the water table, root nodules that produce nitrogen compounds, and protected stoma, reducing transpiration. Also, the deep roots bind the sand together, and the dune grows into a foredune as more sand is blown over the grasses. The grasses add nitrogen to the soil, meaning other, less hardy plants can then colonize the dunes. Typically these are heather, heaths and gorses. These too are adapted to the low soil water content and have small, prickly leaves which reduce transpiration. Heather adds humus to the soil and is usually replaced by coniferous trees, which can tolerate low soil pH, caused by the accumulation and decomposition of organic matter with nitrate leaching. Coniferous forests and heathland are common climax communities for sand dune systems. Young dunes are called yellow dunes and dunes which have high humus content are called grey dunes. Leaching occurs on the dunes, washing humus into the slacks, and the slacks may be much more developed than the exposed tops of the dunes. It is usually in the slacks that more rare species are developed and there is a tendency for the dune slacks' soil to be waterlogged where only marsh plants can survive. In Europe these plants include: creeping willow, cotton grass, yellow iris, reeds, and rushes. As for vertebrates in European dunes, natterjack toads sometimes breed here. Coastal dune floral adaptations Dune ecosystems are extremely difficult places for plants to survive. This is due to a number of pressures related to their proximity to the ocean and confinement to growth on sandy substrates. These include: Little available soil moisture Little available soil organic matter/nutrients/water Harsh winds Salt spray Erosion/shifting and sometimes burial or exposure (from shifting) Tidal influences There are many adaptations plants have evolved to cope with these pressures: Deep taproot to reach water table (Pink Sand Verbena) Shallow but extensive root systems Rhizomes Prostrate growth form to avoid wind/salt spray (Abronia spp., Beach Primrose) Krummholz growth form (Monterrey Cypress-not a dune plant but deals with similar pressures) Thickened cuticle/Succulence to reduce moisture loss and reduce salt uptake (Ambrosia/Abronia spp., Calystegia soldanella) Pale leaves to reduce insolation (Artemisia/Ambrosia spp.) Thorny/Spiky seeds to ensure establishment in vicinity of parent, reduces chances of being blown away or swept out to sea (Ambrosia chamissonis) Gypsum dunes In deserts where large amounts of limestone mountains surround a closed basin, such as at White Sands National Park in south-central New Mexico, occasional storm runoff transports dissolved limestone and gypsum into a low-lying pan within the basin where the water evaporates, depositing the gypsum and forming crystals known as selenite. The crystals left behind by this process are eroded by the wind and deposited as vast white dune fields that resemble snow-covered landscapes. These types of dune are rare, and only form in closed arid basins that retain the highly soluble gypsum that would otherwise be washed into the sea.

short, but upon getting the film developed, realized that the result was a blurred, frameless print. He later said, "So I called up [Wasserman] and said, 'Bart, the film is a disaster. The camera was broken and what I've done hasn't turned out.' And he said, 'Don't worry, David, take the rest of the money and make something else for me. Just give me a print.' End of story." With his leftover money, Lynch decided to experiment with a mix of animation and live action, producing the four-minute short The Alphabet (1968). The film starred Lynch's wife Peggy as a character known as The Girl, who chants the alphabet to a series of images of horses before dying at the end by hemorrhaging blood all over her bed sheets. Adding a sound effect, Lynch used a broken Uher tape recorder to record the sound of Jennifer crying, creating a distorted sound that Lynch found particularly effective. Later describing what had inspired him, Lynch said, "Peggy's niece was having a bad dream one night and was saying the alphabet in her sleep in a tormented way. So that's sort of what started The Alphabet going. The rest of it was just subconscious." Learning about the newly founded American Film Institute, which gave grants to filmmakers who could support their application with a prior work and a script for a new project, Lynch decided to send them a copy of The Alphabet along with a script he had written for a new short film that would be almost entirely live action, The Grandmother. The institute agreed to help finance the work, initially offering him $5,000 out of his requested budget of $7,200, but later granting him the additional $2,200. Starring people he knew from both work and college and filmed in his own house, The Grandmother featured a neglected boy who "grows" a grandmother from a seed to care for him. The film critics Michelle Le Blanc and Colin Odell wrote, "this film is a true oddity but contains many of the themes and ideas that would filter into his later work, and shows a remarkable grasp of the medium". 1970s: Los Angeles and Eraserhead In 1971, Lynch moved with his wife and daughter to Los Angeles, where he began studying filmmaking at the AFI Conservatory, a place he later called "completely chaotic and disorganized, which was great ... you quickly learned that if you were going to get something done, you would have to do it yourself. They wanted to let people do their thing." He began writing a script for a proposed work, Gardenback, that had "unfolded from this painting I'd done". In this venture he was supported by a number of figures at the Conservatory, who encouraged him to lengthen the script and add more dialogue, which he reluctantly agreed to do. All the interference on his Gardenback project made him fed up with the Conservatory and led him to quit after returning to start his second year and being put in first-year classes. AFI dean Frank Daniel asked Lynch to reconsider, believing that he was one of the school's best students. Lynch agreed on the condition that he could create a project that would not be interfered with. Feeling that Gardenback was "wrecked", he set out on a new film, Eraserhead. Eraserhead was planned to be about 42 minutes long (it ended up being 89 minutes), its script was only 21 pages, and Lynch was able to create the film without interference. Filming began on May 29, 1972, at night in some abandoned stables, allowing the production team, which was largely Lynch and some of his friends, including Sissy Spacek, Jack Fisk, cinematographer Frederick Elmes and sound designer Alan Splet, to set up a camera room, green room, editing room, sets as well as a food room and a bathroom. The AFI gave Lynch a $10,000 grant, but it was not enough to complete the film, and under pressure from studios after the success of the relatively cheap feature film Easy Rider, it was unable to give him more. Lynch was then supported by a loan from his father and money that he earned from a paper route that he took up, delivering The Wall Street Journal. Not long into Eraserhead's production, Lynch and Peggy amicably separated and divorced, and he began living full-time on set. In 1977, Lynch married Mary Fisk, sister of Jack Fisk. Lynch has said that not a single reviewer of the film understood it in the way he intended. Filmed in black and white, Eraserhead tells the story of Henry (Jack Nance), a quiet young man living in a dystopian industrial wasteland, whose girlfriend gives birth to a deformed baby whom she leaves in his care. It was heavily influenced by the fearful mood of Philadelphia, and Lynch has called it "my Philadelphia Story". Due to financial problems the filming of Eraserhead was haphazard, regularly stopping and starting again. It was in one such break in 1974 that Lynch created the short film The Amputee, a one-shot film about two minutes long. Lynch proposed that he make The Amputee to present to AFI to test two different types of film stock. Eraserhead was finally finished in 1976. Lynch tried to get it entered into the Cannes Film Festival, but while some reviewers liked it, others felt it was awful, and it was not selected for screening. Reviewers from the New York Film Festival also rejected it, but it was screened at the Los Angeles Film Festival, where Ben Barenholtz, the distributor of the Elgin Theater, heard about it. He was very supportive of the movie, helping to distribute it around the United States in 1977, and Eraserhead subsequently became popular on the midnight movie underground circuit, and was later called one of the most important midnight movies of the 1970s, along with El Topo, Pink Flamingos, The Rocky Horror Picture Show, The Harder They Come and Night of the Living Dead. Stanley Kubrick said it was one of his all-time favorite films. 1980s: The Elephant Man, Dune and Blue Velvet After Eraserhead's success on the underground circuit, Stuart Cornfeld, an executive producer for Mel Brooks, saw it and later said, "I was just 100 percent blown away ... I thought it was the greatest thing I'd ever seen. It was such a cleansing experience." He agreed to help Lynch with his next film, Ronnie Rocket, for which Lynch had already written a script. But Lynch soon realized that Ronnie Rocket, a film that he has said is about "electricity and a three-foot guy with red hair", was not going to be picked up by any financiers, and so he asked Cornfeld to find him a script by someone else that he could direct. Cornfeld found four. On hearing the title of the first, The Elephant Man, Lynch chose it. The Elephant Man's script, written by Chris de Vore and Eric Bergren, was based on a true story, that of Joseph Merrick, a severely deformed man in Victorian London, who was held in a sideshow but later taken under the care of a London surgeon, Frederick Treves. Lynch wanted to make some alterations that would alter the story from true events but in his view make a better plot, but he needed Mel Brooks's permission, as Brooks's company, Brooksfilms, was responsible for production. Brooks viewed Eraserhead, and after coming out of the screening theatre, embraced Lynch, declaring, "You're a madman! I love you! You're in." The Elephant Man starred John Hurt as John Merrick (the name changed from Joseph) and Anthony Hopkins as Treves. Filming took place in London. Though surrealistic and in black and white, it has been called "one of the most conventional" of Lynch's films. The Elephant Man was a huge critical and commercial success, earning eight Academy Award nominations, including Best Director and Best Adapted Screenplay. After The Elephant Man's success, George Lucas, a fan of Eraserhead, offered Lynch the opportunity to direct the third film in his Star Wars trilogy, Return of the Jedi. Lynch refused, arguing that Lucas should direct the film himself as the movie should reflect his own vision, not Lynch's. Soon, the opportunity to direct another big-budget science fiction epic arose when Dino de Laurentiis of the De Laurentiis Entertainment Group asked Lynch to create a film adaptation of Frank Herbert's science fiction novel Dune (1965). Lynch agreed, and in doing so was also contractually obliged to produce two other works for the company. He set about writing a script based upon the novel, initially with both Chris de Vore and Eric Bergren, and then alone when De Laurentiis was unhappy with their ideas. Lynch also helped build some of the sets, attempting to create "a certain look", and particularly enjoyed building the set for the oil planet Giedi Prime, for which he used "steel, bolts, and porcelain". Dune is set in the far future, when humans live in an interstellar empire under a feudal system. The main character, Paul Atreides (Kyle MacLachlan), is the son of a noble who takes control of the desert planet Arrakis, which grows the rare spice melange, the empire's most highly prized commodity. Lynch was unhappy with the work, later saying, "Dune was a kind of studio film. I didn't have final cut. And, little by little, I was subconsciously making compromises" [to his own vision]. Much of his footage was eventually removed from the final theatrical cut, dramatically condensing the plot. Although De Laurentiis hoped it would be as successful as Star Wars, Dune (1984) was a critical and commercial dud; it had cost $45 million to make, and grossed $27.4 million domestically. Later, Universal Studios released an "extended cut" for syndicated television, containing almost an hour of cutting-room-floor footage and new narration. It did not represent Lynch's intentions, but the studio considered it more comprehensible than the original version. Lynch objected to the changes and had his name struck from the extended cut, which has Alan Smithee credited as the director and "Judas Booth" (a pseudonym Lynch invented, reflecting his feelings of betrayal) as the screenwriter. Meanwhile, in 1983, he had begun the writing and drawing of a comic strip, The Angriest Dog in the World, which featured unchanging graphics of a tethered dog that was so angry that it could not move, alongside cryptic philosophical references. It ran from 1983 to 1992 in the Village Voice, Creative Loafing and other tabloid and alternative publications. Around this time Lynch also became interested in photography as an art form, and traveled to northern England to photograph the degrading industrial landscape. Lynch was contractually still obliged to produce two other projects for De Laurentiis, the first a planned sequel to Dune, which due to the film's failure never went beyond the script stage. The other was a more personal work, based on a script Lynch had been working on for some time. Developing from ideas that Lynch had had since 1973, the film, Blue Velvet, was set in the real town of Lumberton, North Carolina, and revolves around a college student, Jeffrey Beaumont (MacLachlan), who finds a severed ear in a field. Investigating further with the help of friend Sandy (Laura Dern), he discovers that it is related to a criminal gang led by psychopath Frank Booth (Dennis Hopper), who has kidnapped the husband and child of singer Dorothy Vallens (Isabella Rossellini) and repeatedly rapes her. Lynch has called the story "a dream of strange desires wrapped inside a mystery story". Lynch included pop songs from the 1960s in the film, including Roy Orbison's "In Dreams" and Bobby Vinton's "Blue Velvet", the latter of which largely inspired the film. Lynch has said, "It was the song that sparked the movie ... There was something mysterious about it. It made me think about things. And the first things I thought about were lawns—lawns and the neighborhood." Other music for the film was composed by Angelo Badalamenti, who wrote the music for most of Lynch's subsequent work. De Laurentiis loved the film, and it received support at some of the early specialist screenings, but the preview screenings to mainstream audiences were very negatively received, with most of the viewers hating the film. Lynch had found success with The Elephant Man, but Blue Velvets controversy with audiences and critics introduced him into the mainstream, and it became a huge critical and moderate commercial success. The film earned Lynch his second Academy Award nomination for Best Director. Woody Allen, whose Hannah and Her Sisters was nominated for Best Picture, said Blue Velvet was his favorite film of the year. In the late 1980s, Lynch began to work in television, directing a short piece, The Cowboy and the Frenchman, for French television in 1989. 1990s: Twin Peaks, Wild at Heart and other works Around this time, he met the television producer Mark Frost, who had worked on such projects as Hill Street Blues, and they decided to start working together on a biopic of Marilyn Monroe based on Anthony Summers's book The Goddess: The Secret Lives of Marilyn Monroe, but it never got off the ground. They went on to work on a comedy script, One Saliva Bubble, but that did not see completion either. While talking in a coffee shop, Lynch and Frost had the idea of a corpse washing up on a lakeshore, and went to work on their third project, initially called Northwest Passage but eventually Twin Peaks (1990–91). A drama series set in a small Washington town where popular high school student Laura Palmer has been murdered, Twin Peaks featured FBI Special Agent Dale Cooper (MacLachlan) as the investigator trying to identify the killer, and discovering not only the murder's supernatural aspects but also many of the townsfolk's secrets; Lynch said, "The project was to mix a police investigation with the ordinary lives of the characters." He later said, "[Mark Frost and I] worked together, especially in the initial stages. Later on we started working more apart." They pitched the series to ABC, which agreed to finance the pilot and eventually commissioned a season comprising seven episodes. During season one Lynch directed two of the seven episodes, devoting more time to his film Wild at Heart, but carefully chose the other episodes' directors. He also appeared in several episodes as FBI agent Gordon Cole. The series was a success, with high ratings in the United States and many other countries, and soon spawned a cult following. Soon a second season of 22 episodes went into production, but ABC executives believed that public interest in the show was decreasing. The network insisted that Lynch and Frost reveal Laura Palmer's killer's identity prematurely, which Lynch grudgingly agreed to do, in what Lynch has called one of his biggest professional regrets. After identifying the murderer and moving from Thursday to Saturday night, Twin Peaks continued for several more episodes, but was canceled after a ratings drop. Lynch, who disliked the direction that writers and directors took in the later episodes, directed the final episode. He ended it with a cliffhanger (like season one had), later saying, "that's not the ending. That's the ending that people were stuck with." Also while Twin Peaks was in production, the Brooklyn Academy of Music asked Lynch and Badalamenti, who wrote the music for Twin Peaks, to create a theatrical piece to be performed twice in 1989 as a part of the New Music America Festival. The result was Industrial Symphony No. 1: The Dream of the Broken Hearted, which starred frequent Lynch collaborators such as Laura Dern, Nicolas Cage and Michael J. Anderson, and contained five songs sung by Julee Cruise. Lynch produced a 50-minute video of the performance in 1990. Meanwhile, he was also involved in creating various commercials for companies including Yves Saint Laurent, Calvin Klein, Giorgio Armani and the Japanese coffee company Namoi, which featured a Japanese man searching Twin Peaks for his missing wife. While Lynch was working on the first few episodes of Twin Peaks, his friend Monty Montgomery "gave me a book that he wanted to direct as a movie. He asked if I would maybe be executive producer or something, and I said 'That's great, Monty, but what if I read it and fall in love with it and want to do it myself?' And he said, 'In that case, you can do it yourself'." The book was Barry Gifford's novel Wild at Heart: The Story of Sailor and Lula, about two lovers on a road trip. Lynch felt that it was "just exactly the right thing at the right time. The book and the violence in America merged in my mind and many different things happened." With Gifford's support, Lynch adapted the novel into Wild at Heart, a crime and road movie starring Nicolas Cage as Sailor and Laura Dern as Lula. Describing its plot as a "strange blend" of "a road picture, a love story, a psychological drama and a violent comedy", Lynch altered much of the original novel, changing the ending and incorporating numerous references to The Wizard of Oz. Despite a muted response from American critics and viewers, Wild at Heart won the Palme d'Or at the 1990 Cannes Film Festival. After Wild at Heart's success, Lynch returned to the world of the canceled Twin Peaks, this time without Frost, to create a film that was primarily a prequel but also in part a sequel. Lynch said, "I liked the idea of the story going back and forth in time." The result, Twin Peaks: Fire Walk with Me (1992), primarily revolved around the last few days in the life of Laura Palmer, and was much "darker" in tone than the TV series, with much of the humor removed, and dealing with such topics as incest and murder. Lynch has said the film is about "the loneliness, shame, guilt, confusion and devastation of the victim of incest". The company CIBY-2000 financed Twin Peaks: Fire Walk with Me, and most of the TV series' cast reprised their roles, though some refused and many were unenthusiastic about the project. The film was a commercial and critical failure in the United States but a hit in Japan, and some critics, such as Mark Kermode, have called it Lynch's "masterpiece". Meanwhile, Lynch worked on some new television shows. He and Frost created the comedy series On the Air (1992), which was canceled after three episodes aired, and he and Monty Montgomery created the three-episode HBO miniseries Hotel Room (1993) about events that happen in one hotel room on different dates. In 1993, Lynch collaborated with Japanese musician Yoshiki on the video for X Japan's song "Longing ~Setsubou no Yoru~". The video was never officially released, but Lynch claimed in his 2018 memoir Room to Dream that "some of the frames are so fuckin' beautiful, you can't believe it." After his unsuccessful TV ventures, Lynch returned to film. In 1997 he released the non-linear, noiresque Lost Highway, which was co-written by Barry Gifford and starred Bill Pullman and Patricia Arquette. The film failed commercially and received a mixed response from critics. Lynch then began work on a film from a script by Mary Sweeney and John E. Roach, The Straight Story, based on a true story: that of Alvin Straight (Richard Farnsworth), an elderly man from Laurens, Iowa, who goes on a 300-mile journey to visit his sick brother (Harry Dean Stanton) in Mount Zion, Wisconsin, by riding lawnmower. Asked why he chose this script, Lynch said, "that's what I fell in love with next", and expressed his admiration of Straight, describing him as "like James Dean, except he's old". Badalamenti wrote the music for the film, saying it was "very different from the kind of score he's done for [Lynch] in the past". Among the many differences from Lynch's other films, The Straight Story contains no profanity, sexuality or violence, and is rated G (general viewing) by the Motion Picture Association of America, which came as "shocking news" to many in the film industry, who were surprised that it "did not disturb, offend or mystify". Le Blanc and Odell write that the plot made it "seem as far removed from Lynch's earlier works as could be imagined, but in fact right from the very opening, this is entirely his film—a surreal road movie". 2000s: Mulholland Drive and other works The same year, Lynch approached ABC again with ideas for a television drama. The network gave Lynch the go-ahead to shoot a two-hour pilot for the series Mulholland Drive, but disputes over content and running time led to the project being shelved indefinitely. But with $7 million from the French production company StudioCanal, Lynch completed the pilot as a film, Mulholland Drive. The film, a non-linear narrative surrealist tale of Hollywood's dark side, stars Naomi Watts, Laura Harring and Justin Theroux. It performed relatively well at the box office worldwide and was a critical success, earning Lynch Best Director at the 2001 Cannes Film Festival (shared with Joel Coen for The Man Who Wasn't There) and Best Director from the New York Film Critics Association. He also received his third Academy Award nomination for Best Director. In 2016, the film was named the best film of the 21st century in a BBC poll of 177 film critics from 36 countries. With the rising popularity of the Internet, Lynch decided to use it as a distribution channel, releasing several new series he had created exclusively on his website, davidlynch.com, which went online on December 10, 2001. In 2002, he created a series of online shorts, DumbLand. Intentionally crude in content and execution, the eight-episode series was later released on DVD. The same year, Lynch released a surreal sitcom, Rabbits, about a family of humanoid rabbits. Later, he made his experiments with Digital Video available in the form of the Japanese-style horror short Darkened Room. In 2006, Lynch's feature film Inland Empire was released. At three hours, it is the longest of his films. Like Mulholland Drive and Lost Highway, it does not follow a traditional narrative structure. It stars Lynch regulars Laura Dern, Harry Dean Stanton and Justin Theroux, with cameos by Naomi Watts and Laura Harring as the voices of Suzie and Jane Rabbit, and a performance by Jeremy Irons. Lynch has called Inland Empire "a mystery about a woman in trouble". In an effort to promote it, he made appearances with a cow and a placard bearing the slogan "Without cheese there would be no Inland Empire". In 2009, Lynch produced a documentary web series directed by his son Austin Lynch and friend Jason S., Interview Project. Interested in working with Werner Herzog, in 2009 Lynch collaborated on Herzog's film My Son, My Son, What Have Ye Done?. With a nonstandard narrative, the film is based on a true story of an actor who committed matricide while acting in a production of the Oresteia, and starred Lynch regular Grace Zabriskie. In 2009 Lynch had plans to direct a documentary on Maharishi Mahesh Yogi consisting of interviews with people who knew him, but nothing has come of it. 2010s: Continued work, Twin Peaks revival In 2010, Lynch began making guest appearances on the Family Guy spin-off The Cleveland Show as Gus the Bartender. He had been convinced to appear in the show by its lead actor, Mike Henry, a fan of Lynch who felt that his whole life had changed after seeing Wild at Heart. Lady Blue Shanghai is a 16-minute promotional film that was written, directed and edited by Lynch for Dior. It was released on the Internet in May 2010. Lynch directed a concert by English new wave band Duran Duran on March 23, 2011. The concert was streamed live on YouTube from the Mayan Theater in Los Angeles as the kickoff to the second season of Unstaged: An Original Series from American Express. "The idea is to try and create on the fly, layers of images permeating Duran Duran on the stage", Lynch said. "A world of experimentation and hopefully some happy accidents". The animated short I Touch a Red Button Man, a collaboration between Lynch and the band Interpol, played in the background during Interpol's concert at the Coachella Valley Music and Arts Festival in April 2011. The short, which features Interpol's song "Lights", was later made available online. It was believed that Lynch was going to retire from the film industry; according to Abel Ferrara, Lynch "doesn't even want to make films any more. I've talked to him about it, OK? I can tell when he talks about it." But in a June 2012 Los Angeles Times interview, Lynch said he lacked the inspiration to start a new movie project, but "If I got an idea that I fell in love with, I'd go to work tomorrow". In September 2012, he appeared in the three-part "Late Show" arc on FX's Louie as Jack Dahl. In November 2012, Lynch hinted at plans for a new film while attending Plus Camerimage in Bydgoszcz, Poland, saying, "something is coming up. It will happen but I don't know exactly when". At Plus Camerimage, Lynch received a lifetime achievement award and the Key to the City from Bydgoszcz's mayor, Rafał Bruski. In a January 2013 interview with the Los Angeles Times, Laura Dern confirmed that she and Lynch were planning a new project, and The New York Times later revealed that Lynch was working on the script. Idem Paris, a short documentary film about the lithographic process, was released online in February 2013. On June 28, 2013, a video Lynch directed for the Nine Inch Nails song "Came Back Haunted" was released. He also did photography for the Dumb Numbers' self-titled album released in August 2013. On October 6, 2014, Lynch confirmed via Twitter that he and Frost would start shooting a new, nine-episode season of Twin Peaks in 2015, with the episodes expected to air in 2016 on Showtime. Lynch and Frost wrote all the episodes. On April 5, 2015, Lynch announced via Twitter that the project was still alive, but he was no longer going to direct because the budget was too low for what he wanted to do. On May 15, 2015, he said via Twitter that he would return to the revival, having sorted out his issues with Showtime. Showtime CEO David Nevins confirmed this, announcing that Lynch would direct every episode of the revival and that the original nine episodes had been extended to 18. Filming was completed by April 2016. The two-episode premiere aired on May 21, 2017. While doing press for Twin Peaks, Lynch was again asked if he had retired from film and seemed to confirm that he had made his last feature film, responding, "Things changed a lot... So many films were not doing well at the box office even though they might have been great films and the things that were doing well at the box office weren't the things that I would want to do". Lynch later said that this statement had been misconstrued: "I did not say I quit cinema, simply that nobody knows what the future holds." Since the last episode of The Return aired, there has been speculation about a fourth season. Lynch did not deny the possibility of another season, but said that if it were to happen, it would not air before 2021. 2020s: Weather reports and short films Lynch did weather reports on his now-defunct website in the early 2000s. He has returned to doing weather reports from his apartment in Los Angeles, along with two new series, What is David Lynch Working on Today?, which details him making collages and Today's Number Is..., where each day he picks a random number from a jar. In one of his weather reports, he detailed a dream he had about being a German soldier shot by an American soldier on D-Day. Lynch rereleased his 2002 film Rabbits on YouTube. On July 17, 2020, his store for merchandise released a set of face masks with Lynch's art on them for the COVID-19 pandemic. In February 2022, it was announced that Lynch had been cast in the Steven Spielberg film The Fabelmans, in a role Variety called "a closely guarded secret". Lynch is reportedly working on a new project for Netflix under the working titles Wisteria and Unrecorded Night. He is set to write and direct 13 episodes with an $85 million budget. Production was set to begin in May 2021 in Los Angeles. Cinematic influences and themes Influences Lynch has said his work is more similar to that of European filmmakers than American ones, and that most films that "get down and thrill your soul" are by European directors. He has expressed his admiration for Federico Fellini, Werner Herzog, Alfred Hitchcock, Roman Polanski, Jacques Tati, Stanley Kubrick, and Billy Wilder. He has said that Wilder's Sunset Boulevard (1950) is one of his favorite pictures, as are Kubrick's Lolita (1962), Tati's Monsieur Hulot's Holiday (1953), Hitchcock's Rear Window (1954), and Herzog's Stroszek (1977). He has also cited Herk Harvey's Carnival of Souls (1962) and Jerzy Skolimowski's Deep End (1970) as influences on his work. Motifs Several themes recur in Lynch's work. Le Blanc and Odell write, "his films are so packed with motifs, recurrent characters, images, compositions and techniques that you could view his entire output as one large jigsaw puzzle of ideas". One of the key themes they note is the usage of dreams | Eraserhead subsequently became popular on the midnight movie underground circuit, and was later called one of the most important midnight movies of the 1970s, along with El Topo, Pink Flamingos, The Rocky Horror Picture Show, The Harder They Come and Night of the Living Dead. Stanley Kubrick said it was one of his all-time favorite films. 1980s: The Elephant Man, Dune and Blue Velvet After Eraserhead's success on the underground circuit, Stuart Cornfeld, an executive producer for Mel Brooks, saw it and later said, "I was just 100 percent blown away ... I thought it was the greatest thing I'd ever seen. It was such a cleansing experience." He agreed to help Lynch with his next film, Ronnie Rocket, for which Lynch had already written a script. But Lynch soon realized that Ronnie Rocket, a film that he has said is about "electricity and a three-foot guy with red hair", was not going to be picked up by any financiers, and so he asked Cornfeld to find him a script by someone else that he could direct. Cornfeld found four. On hearing the title of the first, The Elephant Man, Lynch chose it. The Elephant Man's script, written by Chris de Vore and Eric Bergren, was based on a true story, that of Joseph Merrick, a severely deformed man in Victorian London, who was held in a sideshow but later taken under the care of a London surgeon, Frederick Treves. Lynch wanted to make some alterations that would alter the story from true events but in his view make a better plot, but he needed Mel Brooks's permission, as Brooks's company, Brooksfilms, was responsible for production. Brooks viewed Eraserhead, and after coming out of the screening theatre, embraced Lynch, declaring, "You're a madman! I love you! You're in." The Elephant Man starred John Hurt as John Merrick (the name changed from Joseph) and Anthony Hopkins as Treves. Filming took place in London. Though surrealistic and in black and white, it has been called "one of the most conventional" of Lynch's films. The Elephant Man was a huge critical and commercial success, earning eight Academy Award nominations, including Best Director and Best Adapted Screenplay. After The Elephant Man's success, George Lucas, a fan of Eraserhead, offered Lynch the opportunity to direct the third film in his Star Wars trilogy, Return of the Jedi. Lynch refused, arguing that Lucas should direct the film himself as the movie should reflect his own vision, not Lynch's. Soon, the opportunity to direct another big-budget science fiction epic arose when Dino de Laurentiis of the De Laurentiis Entertainment Group asked Lynch to create a film adaptation of Frank Herbert's science fiction novel Dune (1965). Lynch agreed, and in doing so was also contractually obliged to produce two other works for the company.

Lynch also helped build some of the sets, attempting to create "a certain look", and particularly enjoyed building the set for the oil planet Giedi Prime, for which he used "steel, bolts, and porcelain". Dune is set in the far future, when humans live in an interstellar empire under a feudal system. The main character, Paul Atreides (Kyle MacLachlan), is the son of a noble who takes control of the desert planet Arrakis, which grows the rare spice melange, the empire's most highly prized commodity.

It did not represent Lynch's intentions, but the studio considered it more comprehensible than the original version. Lynch objected to the changes and had his name struck from the extended cut, which has Alan Smithee credited as the director and "Judas Booth" (a pseudonym Lynch invented, reflecting his feelings of betrayal) as the screenwriter. Meanwhile, in 1983, he had begun the writing and drawing of a comic strip, The Angriest Dog in the World, which featured unchanging graphics of a tethered dog that was so angry that it could not move, alongside cryptic philosophical references. It ran from 1983 to 1992 in the Village Voice, Creative Loafing and other tabloid and alternative publications. Around this time Lynch also became interested in photography as an art form, and traveled to northern England to photograph the degrading industrial landscape. Lynch was contractually still obliged to produce two other projects for De Laurentiis, the first a planned sequel to Dune, which due to the film's failure never went beyond the script stage.

The film earned Lynch his second Academy Award nomination for Best Director. Woody Allen, whose Hannah and Her Sisters was nominated for Best Picture, said Blue Velvet was his favorite film of the year. In the late 1980s, Lynch began to work in television, directing a short piece, The Cowboy and the Frenchman, for French television in 1989. 1990s: Twin Peaks, Wild at Heart and other works Around this time, he met the television producer Mark Frost, who had worked on such projects as Hill Street Blues, and they decided to start working together on a biopic of Marilyn Monroe based on Anthony Summers's book The Goddess: The Secret Lives of Marilyn Monroe, but it never got off the ground.

He ended it with a cliffhanger (like season one had), later saying, "that's not the ending. That's the ending that people were stuck with." Also while Twin Peaks was in production, the Brooklyn Academy of Music asked Lynch and Badalamenti, who wrote the music for Twin Peaks, to create a theatrical piece to be performed twice in 1989 as a part of the New Music America Festival. The result was Industrial Symphony No. 1: The Dream of the Broken Hearted, which starred frequent Lynch collaborators such as Laura Dern, Nicolas Cage and Michael J. Anderson, and contained five songs sung by Julee Cruise. Lynch produced a 50-minute video of the performance in 1990. Meanwhile, he was also involved in creating various commercials for companies including Yves Saint Laurent, Calvin Klein, Giorgio Armani and the Japanese coffee company Namoi, which featured a Japanese man searching Twin Peaks for his missing wife. While Lynch was working on the first few episodes of Twin Peaks, his friend Monty Montgomery "gave me a book that he wanted to direct as a movie. He asked if I would maybe be executive producer or something, and I said 'That's great, Monty, but what if I read it and fall in love with it and want to do it myself?' And he said, 'In that case, you can do it yourself'." The book was Barry Gifford's novel Wild at Heart: The Story of Sailor and Lula, about two lovers on a road trip. Lynch felt that it was "just exactly the right thing at the right time. The book and the violence in America merged in my mind and many different things happened." With Gifford's support, Lynch adapted the novel into Wild at Heart, a crime and road movie starring Nicolas Cage as Sailor and Laura Dern as Lula. Describing its plot as a "strange blend" of "a road picture, a love story, a psychological drama and a violent comedy", Lynch altered much of the original novel, changing the ending and incorporating numerous references to The Wizard of Oz. Despite a muted response from American critics and viewers, Wild at Heart won the Palme d'Or at the 1990 Cannes Film Festival.

In 1997 he released the non-linear, noiresque Lost Highway, which was co-written by Barry Gifford and starred Bill Pullman and Patricia Arquette. The film failed commercially and received a mixed response from critics. Lynch then began work on a film from a script by Mary Sweeney and John E. Roach, The Straight Story, based on a true story: that of Alvin Straight (Richard Farnsworth), an elderly man from Laurens, Iowa, who goes on a 300-mile journey to visit his sick brother (Harry Dean Stanton) in Mount Zion, Wisconsin, by riding lawnmower. Asked why he chose this script, Lynch said, "that's what I fell in love with next", and expressed his admiration of Straight, describing him as "like James Dean, except he's old". Badalamenti wrote the music for the film, saying it was "very different from the kind of score he's done for [Lynch] in the past". Among the many differences from Lynch's other films, The Straight Story contains no profanity, sexuality or violence, and is rated G (general viewing) by the Motion Picture Association of America, which came as "shocking news" to many in the film industry, who were surprised that it "did not disturb, offend or mystify". Le Blanc and Odell write that the plot made it "seem as far removed from Lynch's earlier works as could be imagined, but in fact right from the very opening, this is entirely his film—a surreal road movie". 2000s: Mulholland Drive and other works The same year, Lynch approached ABC again with ideas for a television drama. The network gave Lynch the go-ahead to shoot a two-hour pilot for the series Mulholland Drive, but disputes over content and running time led to the project being shelved indefinitely. But with $7 million from the French production company StudioCanal, Lynch completed the pilot as a film, Mulholland Drive. The film, a non-linear narrative surrealist tale of Hollywood's dark side, stars Naomi Watts, Laura Harring and Justin Theroux. It performed relatively well at the box office worldwide and was a critical success, earning Lynch Best Director at the 2001 Cannes Film Festival (shared with Joel Coen for The Man Who Wasn't There) and Best Director from the New York Film Critics Association. He also received his third Academy Award nomination for Best Director. In 2016, the film was named the best film of the 21st century in a BBC poll of 177 film critics from 36 countries. With the rising popularity of the Internet, Lynch decided to use it as a distribution channel, releasing several new series he had created exclusively on his website, davidlynch.com, which went online on December 10, 2001. In 2002, he created a series of online shorts, DumbLand. Intentionally crude in content and execution, the eight-episode series was later released on DVD. The same year, Lynch released a surreal sitcom, Rabbits, about a family of humanoid rabbits. Later, he made his experiments with Digital Video available in the form of the Japanese-style horror short Darkened Room. In 2006, Lynch's feature film Inland Empire was released. At three hours, it is the longest of his films. Like Mulholland Drive and Lost Highway, it does not follow a traditional narrative structure. It stars Lynch regulars Laura Dern, Harry Dean Stanton and Justin Theroux, with cameos by Naomi Watts and Laura Harring as the voices of Suzie and Jane Rabbit, and a performance by Jeremy Irons. Lynch has called Inland Empire "a mystery about a woman in trouble". In an effort to promote it, he made appearances with a cow and a placard bearing the slogan "Without cheese there would be no Inland Empire". In 2009, Lynch produced a documentary web series directed by his son Austin Lynch and friend Jason S., Interview Project. Interested in working with Werner Herzog, in 2009 Lynch collaborated on Herzog's film My Son, My Son, What Have Ye Done?. With a nonstandard narrative, the film is based on a true story of an actor who committed matricide while acting in a production of the Oresteia, and starred Lynch regular Grace Zabriskie. In 2009 Lynch had plans to direct a documentary on Maharishi Mahesh Yogi consisting of interviews with people who knew him, but nothing has come of it. 2010s: Continued work, Twin Peaks revival In 2010, Lynch began making guest appearances on the Family Guy spin-off The Cleveland Show as Gus the Bartender. He had been convinced to appear in the show by its lead actor, Mike Henry, a fan of Lynch who felt that his whole life had changed after seeing Wild at Heart. Lady Blue Shanghai is a 16-minute promotional film that was written, directed and edited by Lynch for Dior. It was released on the Internet in May 2010. Lynch directed a concert by English new wave band Duran Duran on March 23, 2011. The concert was streamed live on YouTube from the Mayan Theater in Los Angeles as the kickoff to the second season of Unstaged: An Original Series from American Express. "The idea is to try and create on the fly, layers of images permeating Duran Duran on the stage", Lynch said. "A world of experimentation and hopefully some happy accidents". The animated short I Touch a Red Button Man, a collaboration between Lynch and the band Interpol, played in the background during Interpol's concert at the Coachella Valley Music and Arts Festival in April 2011. The short, which features Interpol's song "Lights", was later made available online. It was believed that Lynch was going to retire from the film industry; according to Abel Ferrara, Lynch "doesn't even want to make films any more. I've talked to him about it, OK? I can tell when he talks about it." But in a June 2012 Los Angeles Times interview, Lynch said he lacked the inspiration to start a new movie project, but "If I got an idea that I fell in love with, I'd go to work tomorrow". In September 2012, he appeared in the three-part "Late Show" arc on FX's Louie as Jack Dahl. In November 2012, Lynch hinted at plans for a new film while attending Plus Camerimage in Bydgoszcz, Poland, saying, "something is coming up. It will happen but I don't know exactly when". At Plus Camerimage, Lynch received a lifetime achievement award and the Key to the City from Bydgoszcz's mayor, Rafał Bruski. In a January 2013 interview with the Los Angeles Times, Laura Dern confirmed that she and Lynch were planning a new project, and The New York Times later revealed that Lynch was working on the script. Idem Paris, a short documentary film about the lithographic process, was released online in February 2013. On June 28, 2013, a video Lynch directed for the Nine Inch Nails song "Came Back Haunted" was released. He also did photography for the Dumb Numbers' self-titled album released in August 2013. On October 6, 2014, Lynch confirmed via Twitter that he and Frost would start shooting a new, nine-episode season of Twin Peaks in 2015, with the episodes expected to air in 2016 on Showtime. Lynch and Frost wrote all the episodes. On April 5, 2015, Lynch announced via Twitter that the project was still alive, but he was no longer going to direct because the budget was too low for what he wanted to do. On May 15, 2015, he said via Twitter that he would return to the revival, having sorted out his issues with Showtime. Showtime CEO David Nevins confirmed this, announcing that Lynch would direct every episode of the revival and that the original nine episodes had been extended to 18. Filming was completed by April 2016. The two-episode premiere aired on May 21, 2017. While doing press for Twin Peaks, Lynch was again asked if he had retired from film and seemed to confirm that he had made his last feature film, responding, "Things changed a lot... So many films were not doing well at the box office even though they might have been great films and the things that were doing well at the box office weren't the things that I would want to do". Lynch later said that this statement had been misconstrued: "I did not say I quit cinema, simply that nobody knows what the future holds." Since the last episode of The Return aired, there has been speculation about a fourth season. Lynch did not deny the possibility of another season, but said that if it were to happen, it would not air before 2021. 2020s: Weather reports and short films Lynch did weather reports on his now-defunct website in the early 2000s. He has returned to doing weather reports from his apartment in Los Angeles, along with two new series, What is David Lynch Working on Today?, which details him making collages and Today's Number Is..., where each day he picks a random number from a jar. In one of his weather reports, he detailed a dream he had about being a German soldier shot by an American soldier on D-Day. Lynch rereleased his 2002 film Rabbits on YouTube. On July 17, 2020, his store for merchandise released a set of face masks with Lynch's art on them for the COVID-19 pandemic. In February 2022, it was announced that Lynch had been cast in the Steven Spielberg film The Fabelmans, in a role Variety called "a closely guarded secret". Lynch is reportedly working on a new project for Netflix under the working titles Wisteria and Unrecorded Night. He is set to write and direct 13 episodes with an $85 million budget. Production was set to begin in May 2021 in Los Angeles. Cinematic influences and themes Influences Lynch has said his work is more similar to that of European filmmakers than American ones, and that most films that "get down and thrill your soul" are by European directors. He has expressed his admiration for Federico Fellini, Werner Herzog, Alfred Hitchcock, Roman Polanski, Jacques Tati, Stanley Kubrick, and Billy Wilder. He has said that Wilder's Sunset Boulevard (1950) is one of his favorite pictures, as are Kubrick's Lolita (1962), Tati's Monsieur Hulot's Holiday (1953), Hitchcock's Rear Window (1954), and Herzog's Stroszek (1977). He has also cited Herk Harvey's Carnival of Souls (1962) and Jerzy Skolimowski's Deep End (1970) as influences on his work. Motifs Several themes recur in Lynch's work. Le Blanc and Odell write, "his films are so packed with motifs, recurrent characters, images, compositions and techniques that you could view his entire output as one large jigsaw puzzle of ideas". One of the key themes they note is the usage of dreams and dreamlike imagery and structure, something they relate to the "surrealist ethos" of relying "on the subconscious to provide visual drive". This can be seen in Merrick's dream of his mother in The Elephant Man, Cooper's dreams of the red room in Twin Peaks and the "dreamlike logic" of the narratives of Eraserhead, Mulholland Drive and Inland Empire. Of his attitude to dreams, Lynch has said, "Waking dreams are the ones that are important, the ones that come when I'm quietly sitting in a chair, letting my mind wander. When you sleep, you don't control your dream. I like to dive into a dream world that I've made or discovered; a world I choose ... [You can't really get others to experience it, but] right there is the power of cinema." His films are known for their use of magic realism. The motif of dreams is closely linked to his recurring use of drones, real-world sounds and musical styles. Another of Lynch's prominent themes is industry, with repeated imagery of "the clunk of machinery, the power of pistons, shadows of oil drills pumping, screaming woodmills and smoke billowing factories", as seen in the industrial wasteland in Eraserhead, the factories in The Elephant Man, the sawmill in Twin Peaks and the lawnmower in The Straight Story. Of his interest in such things, Lynch has said, "It makes me feel good to see giant machinery, you know, working: dealing with molten metal. And I like fire and smoke. And the sounds are so powerful. It's just big stuff. It means that things are being made, and I really like that." Another theme is the dark underbelly of violent criminal activity in a society, such as Frank Booth's gang in Blue Velvet and the cocaine smugglers in Twin Peaks. The idea of deformity is also found in several of Lynch's films, from The Elephant Man to the deformed baby in Eraserhead, as well as death from head wounds, found in most of Lynch's films. Other imagery common in Lynch's works includes flickering electricity or lights, fire, and stages upon which a singer performs, often surrounded by drapery. Except The Elephant Man and Dune, which are set in Victorian London and a fictitious galaxy respectively, all of Lynch's films are set in the United States, and he has said, "I like certain things about America and it gives me ideas. When I go around and I see things, it sparks little stories, or little characters pop out, so it just feels right to me to, you know, make American films." A number of his works, including Blue Velvet, Twin Peaks and Lost Highway, are intentionally reminiscent of 1950s American culture despite being set in later decades of the 20th century. Lynch has said, "It was a fantastic decade in a lot of ways ... there was something in the air that is not there any more at all. It was such a great feeling, and not just because I was a kid. It was a really hopeful time, and things were going up instead of going down. You got the feeling you could do anything. The future was bright. Little did we know we were laying the groundwork for a disastrous future." Lynch also tends to feature his leading female actors in "split" roles, so that many of his female characters have multiple, fractured identities. This practice began with his casting Sheryl Lee as both Laura Palmer and her cousin Maddy Ferguson in Twin Peaks and continued in his later works. In Lost Highway, Patricia Arquette plays the dual role of Renee Madison/Alice Wakefield; in Mulholland Drive Naomi Watts plays Diane Selwyn/Betty Elms and Laura Harring plays Camilla Rhodes/Rita; in Inland Empire Laura Dern plays Nikki Grace/Susan Blue. The numerous alternative versions of lead characters and fragmented timelines may echo and/or reference the many worlds interpretation of quantum physics and perhaps Lynch's broader interest in quantum mechanics. Some have suggested that Lynch's love for Hitchcock's Vertigo, which employs a split lead character (the Judy Barton and Madeleine Elster characters, both portrayed by Kim Novak) may have influenced this aspect of his work. His films frequently feature characters with supernatural or omnipotent qualities. They can be seen as physical manifestations of various concepts, such as hatred or fear. Examples include The Man Inside the Planet in Eraserhead, BOB in Twin Peaks, The Mystery Man in Lost Highway, The Bum in Mulholland Drive, and The Phantom in Inland Empire. Lynch approaches his characters and plots in a way that steeps them in a dream state rather than reality. Recurring collaborators Lynch is also widely noted for his collaborations with various production artists and composers on his films and other productions. He frequently works with Angelo Badalamenti to compose music for his productions, former wife Mary Sweeney as a film editor, casting director Johanna Ray, and cast members Harry Dean Stanton, Jack Nance, Kyle MacLachlan, Naomi Watts, Isabella Rossellini, Grace Zabriskie, and Laura Dern.

others, he described as "scary and bizarre and violent and nasty—the ones your mother didn’t want you to have." Early films that later proved influential on Cronenberg's career include standard avant-garde, horror, science fiction, and thriller films, such as Un Chien Andalou, Vampyr, War of the Worlds, Freaks, Creature from the Black Lagoon, Alphaville, Performance, and Duel. However, Cronenberg has also cited less obvious films as influences, including comedies like The Bed Sitting Room, as well as Disney cartoons such as Bambi and Dumbo. Cronenberg said he found these two Disney animated films, as well as Universal's live-action Blue Lagoon, "terrifying" which influenced his approach to horror. Cronenberg went on to say that Bambi was the "first important film" he ever saw, citing the moment when Bambi's mother died as particularly powerful. Cronenberg even wished to screen Bambi as part of a museum exhibition of his influences, but Disney refused him permission. In terms of conventional horror films that frightened him, Cronenberg cited Don't Look Now. Cronenberg began writing as a child and did so constantly, mainly working in the science fiction genre. He attended high school at Harbord Collegiate Institute and North Toronto Collegiate Institute. A keen interest in science, especially botany and lepidopterology, led him to enter the Honours Science program at the University of Toronto in 1963, but he switched to Honours English Language and Literature later in his first year. Cronenberg's fascination with the film Winter Kept Us Warm (1966), by classmate David Secter, sparked his interest in film. He began frequenting film camera rental houses, learning the art of filmmaking, and made two 16mm films (Transfer and From the Drain). Inspired by the New York underground film scene, he founded the Toronto Film Co-op with Iain Ewing and Ivan Reitman. After taking a year off to travel in Europe, he returned to Canada in 1967 and graduated from University College of the University of Toronto at the top of his class. Career After two short sketch films and two short art-house features (the black-and-white Stereo and the colour Crimes of the Future) Cronenberg went into partnership with Ivan Reitman. The Canadian government provided financing for his films throughout the 1970s. During this period, he focused on his signature "body horror" films such as Shivers and Rabid, the latter of which provided pornographic actress Marilyn Chambers with work in a different genre, although Cronenberg's first choice for the role had been a then little-known Sissy Spacek. Rabid was a breakthrough with international distributors, and his next two horror features, The Brood and Scanners, gained stronger support. Even at this stage however, Cronenberg showed variety, by making Fast Company between The Brood and Rabid, a project reflecting his interest in car racing and bike gangs. Cronenberg has cited William S. Burroughs and Vladimir Nabokov as influences. Perhaps the best example of a film that straddles the line between his works of personal chaos and psychological confusion is Cronenberg's 1991 "adaptation" of Naked Lunch (1959), his literary hero William S. Burroughs' most controversial book. The novel was considered "unfilmable", and Cronenberg acknowledged that a straight translation into film would "cost 400 million dollars and be banned in every country in the world". Instead—much like in his earlier film, Videodrome—he consistently blurred the lines between what appeared to be reality and what appeared to be hallucinations brought on by the main character's drug addiction. Some of the book's "moments" (as well as incidents loosely based upon Burroughs' life) are presented in this manner within the film. Cronenberg stated that while writing the screenplay for Naked Lunch (1991), he felt a moment of synergy with Burroughs' writing style. He felt the connection between his screenwriting style and Burroughs' prose style was so strong, that he jokingly remarked that should Burroughs pass on, "I'll just write his next book." Cronenberg has said that his films should be seen "from the point of view of the disease", and that in Shivers, for example, he identifies with the characters after they become infected with the anarchic parasites. Disease and disaster, in Cronenberg's work, are less problems to be overcome than agents of personal transformation. Of his characters' transformations, Cronenberg said, "But because of our necessity to impose our own structure of perception on things we look on ourselves as being relatively stable. But, in fact, when I look at a person I see this maelstrom of organic, chemical and electron chaos; volatility and instability, shimmering; and the ability to change and transform and transmute." Similarly, in Crash (1996), people who have been injured in car crashes attempt to view their ordeal as "a fertilizing rather than a destructive event". In 2005, Cronenberg publicly disagreed with Paul Haggis' choice of the same name for the latter's Oscar-winning film Crash (2004), arguing that it was "very disrespectful" to the "important and seminal" J.G. Ballard novel on which Cronenberg's film was based. Aside from The Dead Zone (1983) and The Fly (1986), Cronenberg has not generally worked within the world of big-budget, mainstream Hollywood filmmaking, although he has had occasional near misses. At one stage he was considered by George Lucas as a possible director for Return of the Jedi (1983) but was passed over. Cronenberg also worked for nearly a year on a version of Total Recall (1990), but experienced "creative differences" with producers Dino De Laurentiis and Ronald Shusett; a different version of the film was eventually made by Paul Verhoeven. A fan of Philip K. Dick's, author of "We Can Remember it For You Wholesale", the short story upon which the film was based, Cronenberg related in the 1992 biography/overview of his work, Cronenberg on Cronenberg, that his dissatisfaction with what he envisioned the film to be and what it ended up being pained him so greatly that for a time, he suffered a migraine just thinking about it, akin to a needle piercing his eye. In the late 1990s, Cronenberg was announced as director of a sequel to another Verhoeven film, Basic Instinct (1992), but this also fell through. His thriller A History of Violence (2005) is one of his highest budgeted and most accessible to date. He has said that the decision to direct it was influenced by his having had to defer some of his salary on the low-budgeted Spider (2002), but it was one of his most critically acclaimed films to date, along with Eastern Promises (2007), a film about the struggle of one man to gain power in the Russian Mafia. Cronenberg has collaborated with composer Howard Shore on all of his films since The Brood (1979), (see List of film director and composer collaborations) with the exception of The Dead Zone (1983), which was scored by Michael Kamen. Other regular collaborators include actor Robert Silverman, art director Carol Spier (also his sister) sound editor Bryan Day, film editor Ronald Sanders, his sister, costume designer Denise Cronenberg, and, from 1979 until 1988, cinematographer Mark Irwin. In 2008, Cronenberg directed Howard Shore's first opera, The Fly. Since Dead Ringers (1988), Cronenberg has worked with cinematographer Peter Suschitzky on each of his films (see List of film director and cinematographer collaborations). Suschitzky was the director of photography for The Empire Strikes Back (1980), and Cronenberg remarked that Suschitzky's work in that film "was the only one of those movies that actually looked good", which was a motivating factor to work with him on Dead Ringers. Although Cronenberg has worked with a number of Hollywood stars, he remains a staunchly Canadian filmmaker, with nearly all of his films (including major studio vehicles The Dead Zone and The Fly) having been filmed in his home province Ontario. Notable exceptions include M. Butterfly (1993), most of which was shot in China, Spider, and Eastern Promises (2007), which were both filmed primarily in England, and A Dangerous Method (2011), which was filmed in Germany and Austria. Rabid and Shivers were shot in and around Montreal. Most of his films have been at least partially financed by Telefilm Canada, and Cronenberg, a vocal supporter of government-backed film projects, has said: "Every country needs [a system of government grants] to have a national cinema in the face of Hollywood". Cronenberg has also appeared as an actor in other directors' films. Most of his roles are cameo appearances, as in the films Into the Night (1985), Blood and Donuts (1995), To | the unraveling of his first marriage, which caused both Cronenberg and his daughter Cassandra a great deal of turmoil. The character Nola Carveth, mother of the brood, is based on Cassandra's mother. Cronenberg said that he found the shooting of the climactic scene, in which Nola was strangled by her husband, to be "very satisfying". In a September 2013 interview, Cronenberg revealed that Roman Catholic film director Martin Scorsese admitted to him that he was intrigued by Cronenberg's early work but was subsequently "terrified" to meet him in person. Cronenberg responded to Scorsese: "You're the guy who made Taxi Driver and you're afraid to meet me?" In the same interview, Cronenberg identified as an atheist. "Anytime I've tried to imagine squeezing myself into the box of any particular religion, I find it claustrophobic and oppressive," Cronenberg elaborated. "I think atheism is an acceptance of what is real." In the same interview, Cronenberg revealed that it depends on the "time of day" as to whether or not he is afraid of death. He further stated that he is not concerned about posthumous representations of his film work: "It wouldn't disturb me to think that my work would just sink beneath the waves without trace and that would be it. So what? It doesn't bother me." In Cronenberg on Cronenberg, the director further elaborated that he was raised in a secular Jewish home, and while he and his family had no disdain towards any religion, such matters were not discussed. In the same book, Cronenberg said that in his teens he went through a phase where he wondered about the existence of God, but ultimately came to the conclusion that the God concept was developed to cope with the fear of death. In a 2007 interview, Cronenberg explained the role atheism plays in his work. He stated, "I'm interested in saying, 'Let us discuss the existential question. We are all going to die, that is the end of all consciousness. There is no afterlife. There is no God. Now what do we do.' That's the point where it starts getting interesting to me." In Cronenberg's later films (e.g. A History of Violence, Eastern Promises and A Dangerous Method) openly religious characters become more common. During an interview for A History of Violence, Cronenberg even chose to identify as a materialist rather than an atheist, stating, "I’m not an atheist, but for me to turn away from any aspect of the human body to me is a philosophical betrayal. And there’s a lot of art and religion whose whole purpose is to turn away from the human body. I feel in my art that my mandate is to not do that." In a separate 2013 interview, Cronenberg discussed the role religion plays in his films, using Eastern Promises as the main example: I'm an atheist but not all my characters are atheists. So it's true that I don't think about God ever as part of my life or anything. But if you're a dramatist and you are working with characters who come from a particular culture, you have to accept their understanding of life, and with passion. So the Nikolai character, I'm pretty sure he believes in God and most of the other characters in the movie do too. Some of them are Muslim, some of them are Eastern Orthodox, and that's a part of their life, a part of their understanding of suffering. Because everybody in life suffers but not everybody thinks of that in religious terms. These people do. And they think of suffering as a way to salvation, also in religious terms. I am their God really, as I am creating them; that's religious in itself. I am a very hardcore atheist believe me but you become like an actor really, as a director or a writer. You must take on the character as that character is and believe in it as you're playing it. To allow that character to exist as he would exist. That's really what it's all about, so I have no problem with characters who are religious and believe in God. I would have a problem if that was the point of the whole story because that bores me and I just don't have any emotional or intellectual respect for it, frankly. Filmography Films Acting roles Short films Television TV movies TV series Acting roles Commercials Awards and recognition Cronenberg has appeared on various "Greatest Director" lists. In 2004, Science Fiction magazine Strange Horizons named him the second greatest director in the history of the genre, ahead of better known directors such as Steven Spielberg, James Cameron, Jean-Luc Godard, and Ridley Scott. In the same year, The Guardian listed him 9th on their list of "The world's 40 best directors". In 2007, Total Film named him as the 17th greatest director of all-time. Film professor Charles Derry, in his overview of the horror genre Dark Dreams, called the director one of the most important in his field, and that "no discussion of contemporary horror film can conclude without reference to the films of David Cronenberg." Cronenberg received the Special Jury Prize at the 1996 Cannes Film Festival for Crash. In 1999, he was inducted onto Canada's Walk of Fame, awarded the Silver Bear Award at the 49th Berlin International Film Festival. and that November received the Governor General's Performing Arts Award, Canada's highest honour in the performing arts. In 2002, he was made an Officer of the Order of Canada, and was promoted to Companion of the Order of Canada (the order's highest rank) in 2014. In 2006 he was awarded the Cannes Film Festival's lifetime achievement award, the Carrosse d'Or. In 2009 Cronenberg received the Légion d'honneur from the government of France. The following year Cronenberg was named an honorary patron of the University Philosophical Society, Trinity College Dublin. In 2012, he received the Queen Elizabeth II Diamond Jubilee Medal. The opening of the "David Cronenberg: Evolution" Toronto International Film Festival (TIFF) exhibition occurred on October 30, 2013. Held at the TIFF Bell Lightbox venue, the exhibition paid tribute to the director's entire filmmaking career and the festival's promotional material referred to Cronenberg as "one of Canada's most prolific and iconic filmmakers". The exhibition was shown internationally following the conclusion of the TIFF showing on January 19, 2014. In 2014, he was made a Member of the Order of Ontario in recognition for being "Canada's most celebrated internationally acclaimed filmmaker". In April 2018, it was announced that Cronenberg would receive the honorary Golden Lion at the 75th Venice International Film Festival.

in the Twin 125-mile qualifying race, his record eighth-straight win in the event. Once again in the hunt for the Daytona 500 with 10 laps to go, Earnhardt was taken out of contention by a late crash which sent his car upside down on the backstretch. He hit the low point of his year when he blacked out early in the Mountain Dew Southern 500 at Darlington in September, causing him to hit the wall. Afterward, he was disoriented, and it took several laps before he could find his pit stall. When asked, Earnhardt complained of double vision which made it difficult to pit. Mike Dillon (Richard Childress's son-in-law) was brought in to relieve Earnhardt for the remainder of the race. Earnhardt was evaluated at a local hospital and cleared to race the next week, but the cause of the blackout and double vision was never determined. Despite no wins, Earnhardt finished the season fifth in the final standings with 7 top fives and 16 top tens, with an average finish of 12.1. On February 15, 1998, Earnhardt finally won the Daytona 500 in his 20th attempt after failing to win in his previous 19 attempts. He began the season by winning his Twin 125-mile qualifier race for the ninth straight year, and the week before was the first to drive around the track under the newly installed lights, for coincidentally 20 laps. On race day, he showed himself to be a contender early. Halfway through the race, however, it seemed that Jeff Gordon had the upper hand. But by lap 138, Earnhardt had taken the lead and thanks to a push by teammate Mike Skinner, he maintained it. Earnhardt made it to the caution-checkered flag before Bobby Labonte. Afterwards, there was a large show of respect for Earnhardt, in which every crew member of every team lined pit road to shake his hand as he made his way to victory lane. Earnhardt then drove his No. 3 into the infield grass, starting a trend of post-race celebrations. He spun the car twice, throwing grass and leaving tire tracks in the shape of a No. 3 in the grass. He then spoke about the victory, saying, "I have had a lot of great fans and people behind me all through the years and I just can't thank them enough. The Daytona 500 is ours. We won it, we won it, we won it!" The rest of the season did not go as well, and the Daytona 500 was his only victory that year. Despite that, he did almost pull off a Daytona sweep, where he was one of the contenders for the win in the first nighttime Pepsi 400, but a pit stop late in the race in which a rogue tire cost him the race win. He slipped to 12th in the point standings halfway through the season, and Richard Childress decided to make a crew chief change, taking Mike Skinner's crew chief Kevin Hamlin and putting him with Earnhardt while giving Skinner Larry McReynolds (Earnhardt's crew chief). Earnhardt finished the 1998 season eighth in the final points standings, with 1 win, 5 top fives, and 13 top tens, with an average finish of 16.2. Before the 1999 season, fans began discussing Earnhardt's age and speculating that with his son, Dale Jr., making his Winston Cup debut, Earnhardt might be contemplating retirement. Earnhardt swept both races for the year at Talladega, leading some to conclude that his talent had become limited to the restrictor plate tracks, which require a unique skill set and an exceptionally powerful racecar to win. But halfway through the year, Earnhardt began to show some of the old spark. In the August race at Michigan, he led laps late in the race and nearly pulled off his first win on a non-restrictor-plate track since 1996. One week later, he provided NASCAR with one of its most controversial moments. At the Bristol night race, Earnhardt found himself in contention to win his first short track race since Martinsville in 1995. When a caution came out with 15 laps to go, leader Terry Labonte got hit from behind by the lapped car of Darrell Waltrip. His spin put Earnhardt in the lead with five cars between him and Labonte with five laps to go. Labonte had four fresh tires, and Earnhardt was driving on old tires, which made Earnhardt's car considerably slower. Labonte caught Earnhardt and passed him coming to the white flag, but Earnhardt drove hard into turn two, bumping Labonte and spinning him around. Earnhardt collected the win while spectators booed and made obscene gestures. "I didn't mean to turn him around, I just wanted to rattle his cage," Earnhardt said of the incident. He finished seventh in the standings that year, with 3 wins, 7 top fives, and 21 top tens, with an average finish of 12.0. 2000 In the 2000 season, Earnhardt had a resurgence, which was commonly attributed to neck surgery he underwent to correct a lingering injury from his 1996 Talladega crash. He scored what were considered the two most exciting wins of the year—winning by 0.010 seconds over Bobby Labonte at Atlanta, then gaining seventeen positions in the final four laps to win at Talladega, claiming his only No Bull million-dollar bonus along with his record 10th win at the track. Earnhardt also had second-place runs at Richmond and Martinsville, tracks where he had struggled through the late 1990s. On the strength of those performances, Earnhardt got to second in the standings. However, poor performances at the road course of Watkins Glen, where he wrecked coming out of the chicane, a wreck with Kenny Irwin Jr. while leading the spring race at Bristol, and mid-pack runs at intermediate tracks like Charlotte and Dover in a season dominated by the Ford Taurus in those tracks from Roush, Yates, and Penske, coupled with Bobby Labonte's extreme consistency, denied Earnhardt an eighth championship title. Earnhardt finished 2000 with two wins, 13 top fives, 24 top tens, an average finish of 9.4, and was the only driver besides Labonte to finish the season with zero DNF's. Death During the Daytona 500 at Daytona International Speedway on February 18, 2001, Earnhardt was killed in a three-car crash on the final lap of the race. He collided with Ken Schrader after making small contact with Sterling Marlin and hit the outside wall head-on. He had been blocking Schrader on the outside and Marlin on the inside at the time of the crash. Earnhardt's and Schrader's cars both slid off the track's asphalt banking into the infield grass just inside of turn 4. Seconds later, his driver Michael Waltrip won the race, with his teammate and son Dale Earnhardt Jr. finishing second. Earnhardt's death was officially pronounced at the Halifax Medical Center at 5:16 PM Eastern Standard Time (22:16 UTC); he was 49 years old. NASCAR president Mike Helton confirmed Earnhardt's death in a statement to the press. An autopsy conducted on February 19, 2001, concluded that Earnhardt sustained a fatal basilar skull fracture. Days later, on February 22, public funeral services were held at the Calvary Church in Charlotte, North Carolina. Aftermath After Earnhardt's death, two investigations led by the police and NASCAR commenced; nearly every detail of the crash was made public. The allegations of seatbelt failure resulted in Bill Simpson's resignation from the company bearing his name, which manufactured the seatbelts used in Earnhardt's car and nearly every other NASCAR driver's car. NASCAR implemented rigorous safety improvements, such as mandating the HANS device, which Earnhardt refused to wear after finding it restrictive and uncomfortable. Several press conferences were held in the days following Earnhardt's death. After driver Sterling Marlin and his relatives received hate mail and death threats from angry fans, Waltrip and Earnhardt Jr. absolved him of any responsibility. Richard Childress made a public pledge that the number 3 would never again adorn the side of a black race car with a GM Goodwrench sponsorship. The number returned for the 2014 season, this time not sponsored by GM Goodwrench (which was rebranded GM Certified Service in 2011), driven by Childress's grandson Austin Dillon. At this time, his team was re-christened as the No. 29 team. Childress' second-year Busch Series driver Kevin Harvick was named as Earnhardt's replacement, beginning with the 2001 Dura Lube 400 at North Carolina Speedway. Special pennants bearing the No. 3 were distributed to everyone at the track to honor Earnhardt, and the Childress team wore blank uniforms out of respect, something which disappeared quickly and was soon replaced by the previous GM Goodwrench Service Plus uniforms. Harvick's car always displayed the Earnhardt stylized number 3 on the "B" posts (metal portion on each side of the car to the rear of the front windows) above the number 29 until the end of 2013, when he departed for Stewart-Haas Racing. Fans began honoring Earnhardt by holding three fingers aloft on the third lap of every race, a black screen of No. 3 in the beginning of NASCAR Thunder 2002 before the EA Sports logo, and the television coverage of NASCAR on Fox and NASCAR on NBC went silent for each third lap from Rockingham to the following year's race there in honor of Earnhardt, unless on-track incidents brought out the caution flag on the third lap. Three weeks after Earnhardt's death, Harvick, driving a car that had been prepared for Earnhardt, scored his first career Cup win at Atlanta. On the final lap of the 2001 Cracker Barrel Old Country Store 500, he beat Jeff Gordon by .006 seconds (the margin being 0.004 of a second closer than Earnhardt had won over Bobby Labonte at the same race a year ago) in an identical photo finish, and the images of Earnhardt's longtime gas man Danny "Chocolate" Myers crying after the victory, Harvick's tire-smoking burnout on the frontstretch with three fingers held aloft outside the driver's window. The win was also considered cathartic for a sport whose epicenter had been ripped away. Harvick would win another race at the inaugural event at Chicagoland en route to a ninth-place finish in the final points, and won Rookie of the Year honors along with the 2001 NASCAR Busch Series Championship. Dale Earnhardt, Inc. won five races in the 2001 season, beginning with Steve Park's victory in the race at Rockingham just one week after Earnhardt's death. Earnhardt Jr. and Waltrip finished first and second in the series' return to Daytona in July for the Pepsi 400, a reverse of the finish in the Daytona 500. Earnhardt Jr. also won the fall races at Dover (first post 9/11 race) and Talladega and came to an eighth-place points finish. Earnhardt's remains were interred at his estate in Mooresville, North Carolina after a private funeral service on February 21, 2001. No. 3 car Earnhardt drove the No. 3 car for the majority of his career, spanning the latter half of the 1981 season, and then again from 1984 until his death in 2001. Although he had other sponsors during his career, his No. 3 is associated in fans' minds with his last sponsor GM Goodwrench and his last color scheme — a predominantly black car with bold red and silver trim. The black and red No. 3 continues to be one of the most famous logos in North American motor racing. A common misconception was that Richard Childress Racing "owned the rights" to the No. 3 in NASCAR competition (fueled by the fact that Kevin Harvick's car had a little No. 3 as an homage to Earnhardt from 2001 to 2013 and the usage of the No. 3 on the Camping World Truck Series truck of Ty Dillon when he ran in that series), but in fact NASCAR, and no specific team, owns the rights to this or any other number. According to established NASCAR procedures, Richard Childress Racing had priority over other teams if they chose to reuse the number, which they did when Austin Dillon was promoted to the Cup series in 2014. While Richard Childress Racing owns the stylized No. 3 logos used during Earnhardt's lifetime (and used presently with Dillon), those rights would hypothetically not prevent a future racing team from using a different No. 3 design (also, a new No. 3 team would most likely, in any case, need to create logos which fit with their sponsor's logos). In 2004, ESPN released a made-for-TV movie entitled 3: The Dale Earnhardt Story, which used a new (but similarly colored) No. 3 logo. The movie was a sympathetic portrayal of Earnhardt's life, but the producers were sued for using the No. 3 logo. In December 2006, the ESPN lawsuit was settled, but details were not released to the public. Dale Earnhardt Jr. made two special appearances in 2002 in a No. 3 Busch Series car: these appearances were at the track where his father died (Daytona) and the track where he made his first Winston Cup start (Charlotte). Earnhardt Jr. won the first of those two races, which was the season-opening event at Daytona. He also raced a No. 3 sponsored by Wrangler on July 2, 2010, for Richard Childress Racing at Daytona. In a green-white-checker finish he outran Joey Logano to win his second race in the No. 3. Otherwise, the No. 3 was missing from the national touring series until September 5, 2009, when Austin Dillon, the 19-year-old grandson of Richard Childress, debuted an RCR-owned No. 3 truck in the Camping World Truck Series. Dillon and his younger brother Ty Dillon drove the No. 3 in various lower level competitions for several years, including the Camping World East Series. In 2012, Austin Dillon began driving in the Nationwide Series full-time, using the No. 3; he had previously used the No. 33 while driving in that series part-time. Richard Childress Racing entered a No. 3 in the Daytona truck race on February 13, 2010, painted identically to when Earnhardt drove it, but with a sponsorship from Bass Pro Shops. It was driven by Austin Dillon. It was involved in a wreck almost identical to that which took the life of Earnhardt: being spun out, colliding with another vehicle, and being turned into the outside wall in turn number four. He walked away unscathed. Dillon again returned to a No. 3 marked racecar when he started fifth in the 2012 Daytona Nationwide Series opener in an Advocare sponsored black Chevrolet Impala. On December 11, 2013, RCR announced that Austin Dillon would drive the No. 3 car in the upcoming 2014 Sprint Cup season, bringing the number back to the series for the first time in 13 years. Only the former International Race of Champions actually retired the No. 3, which they did in a rule change effective in 2004. Until the series folded in 2007, anyone wishing to use the No. 3 again had to use No. 03 instead. Formula One driver Daniel Ricciardo chose the number 3 as his permanent racing number when F1's rules changed to allow drivers to choose their own numbers for 2014 and stated on Twitter that part of the reason for his choice was that he was a fan of Earnhardt's, while his helmet design features the number stylized in the same way. Legacy "Earnhardt Tower", a seating section at Daytona International Speedway was opened and named in his honor a month before his death at the track. Earnhardt has several roads named after him, including a street in his hometown Kannapolis. Dale Earnhardt Boulevard (originally Earnhardt Road) is marked as exit 60 off Interstate 85, northeast of Charlotte. Dale Earnhardt Drive is also the start of The Dale Journey Trail, a self-guided driving tour of landmarks in the lives of Earnhardt and his family. The North Carolina Department of Transportation switched the designation of a road between Kannapolis and Mooresville near the headquarters of DEI (that used to be called NC 136) with NC 3, which was in Currituck County. In addition, exit 72 off Interstate 35W, one of the entrances to Texas Motor Speedway, is named "Dale Earnhardt Way". Between the 2004 and 2005 JGTC (renamed Super GT from 2005) season, Hasemi Sport competed in the series with a sole black G'Zox-sponsored Nissan 350Z with the same number and letterset as Earnhardt on the roof. During the NASCAR weekend races at Talladega Superspeedway on April 29, 2006 – May 1, 2006, the DEI cars competed in identical special black paint schemes on Dale Earnhardt Day, which is held annually on his birthday—April 29. Martin Truex Jr., won the Aaron's 312 in the black car, painted to reflect Earnhardt's Intimidating Black No. 3 NASCAR Busch Grand National series car. In the Nextel Cup race on May 1, No. 8 Dale Earnhardt Jr.; No. 1 Martin Truex Jr.; and No. 15 Paul Menard competed in cars with the same type of paint scheme. On June 18, 2006, at Michigan for the 3M Performance 400, Earnhardt Jr. ran a special vintage Budweiser car to honor his father and his grandfather Ralph Earnhardt. He finished third after rain caused the race to be cut short. The car was painted to resemble Ralph's 1956 dirt cars, and carried 1956-era Budweiser logos to complete the throwback look. In the summer of 2007, Dale Earnhardt, Inc. (DEI) with the Dale Earnhardt Foundation, announced it will fund an annual undergraduate scholarship at Clemson University in Clemson, South Carolina for students interested in motorsports and automotive engineering. Scholarship winners are also eligible to work at DEI in internships. The first winner was William Bostic, a senior at Clemson majoring in mechanical engineering. In 2008, on the 50th anniversary of the first Daytona 500 race, DEI and RCR teamed up to make a special COT sporting Earnhardt's 1998 Daytona 500 paint scheme to honor the tenth anniversary of his Daytona 500 victory. In a tribute to all previous Daytona 500 winners, the winning drivers appeared in a lineup on stage, in chronological order. The throwback No. 3 car stood in the infield, in the approximate position Earnhardt would have taken in the processional. The throwback car featured the authentic 1998-era design on a current-era car, a concept similar to modern throwback jerseys in other sports. The car was later sold in 1:64 and 1:24 scale models. The Intimidator 305 roller coaster has been open since April 2, 2010, at Kings Dominion in Doswell, Virginia. Named after Earnhardt, the ride's trains are modeled after his black-and-red Chevrolet. Another Intimidator was built at Carowinds, in Charlotte, North Carolina, which opened on March 27, 2010. The entrance to both roller coasters feature signage that shows Earnhardt's legacy along with one of his cars. Atlanta Braves assistant coach Ned Yost was a friend of Earnhardt, and Richard Childress. When Yost was named Milwaukee Brewers manager, he changed jersey numbers, from No. 5 to No. 3 in Earnhardt's honor. (No. 3 is retired by the Braves in honor of outfielder Dale Murphy, so Yost could not make the change while in Atlanta.) When Yost was named Kansas City Royals assistant coach, he wore No. 2 for the 2010 season, even when he was named manager in May 2010, but for the 2011 season, he switched back to No. 3. During the third lap of the 2011 Daytona 500 (a decade since Earnhardt's death), the commentators on FOX fell silent while fans raised three fingers in a similar fashion to the tributes throughout 2001. The north entrance to New Avondale City Center in Arizona will bear the name Dale Earnhardt Drive. Avondale is where Earnhardt | his home in 1973 at age 45, it took many years before Dale felt as though he had finally "proven" himself to his father. Earnhardt had four siblings: two brothers, Danny (died 2021) and Randy (died 2013); and two sisters, Cathy and Kaye. In 1968, at the age of 17, Earnhardt married his first wife, Latane Brown. With her, Earnhardt fathered his first son, Kerry, a year later. Earnhardt and Brown divorced in 1970. In 1971, Earnhardt married his second wife, Brenda Gee, the daughter of NASCAR car builder Robert Gee. In his marriage with Gee, Earnhardt had two more children: a daughter, Kelley King Earnhardt, in 1972, and a son, Dale Earnhardt Jr., in 1974. Not long after Dale Jr. was born, Earnhardt and Gee divorced. Earnhardt then married his third wife, Teresa Houston, in 1982. She gave birth to their daughter, Taylor Nicole Earnhardt, in 1988. Taylor and her husband, Brandon Putnam, are professional rodeo performers. NASCAR career Early Winston Cup career (1975–1978) Earnhardt began his professional career in the NASCAR Winston Cup Series in 1975, making his points race debut at Charlotte Motor Speedway in North Carolina in the longest race on the Cup circuit—the 1975 World 600. He had made his Grand National debut in 1974 in an unofficial invitational exhibition race at Metrolina Speedway, where with eight laps to go he got under Richard Childress and spun out when battling for third. He drove the No. 8 Ed Negre Dodge Charger and finished 22nd in that race, just one spot ahead of his future car owner, Richard Childress. Earnhardt competed in eight more races until 1979. Rod Osterlund Racing (1979–1980) When he joined car owner Rod Osterlund Racing in a season that included a rookie class of future stars including Earnhardt, Harry Gant, and Terry Labonte in his rookie season, Earnhardt won one race at Bristol, captured four poles, scored eleven Top 5s and seventeen Top 10s, and finished seventh in the points standings despite missing four races due to a broken collarbone, winning Rookie of the Year honors. During his sophomore season, Earnhardt, now with 20-year-old Doug Richert as his crew chief, began the season winning the Busch Clash. With wins at Atlanta, Bristol, Nashville, Martinsville, and Charlotte, Earnhardt won his first Winston Cup points championship. He is the only driver in NASCAR Winston Cup history to follow a Rookie of the Year title with a NASCAR Winston Cup Championship the next season. He was also the third driver in NASCAR history to win both the Rookie of the Year and Winston Cup Series championship, following David Pearson (1960, 1966) and Richard Petty (1959, 1964). Ten drivers have since joined this exclusive club: Rusty Wallace (1984, 1989), Alan Kulwicki (1986, 1992), Jeff Gordon (1993, 1995), Tony Stewart (1999, 2002), Matt Kenseth (2000, 2003), Kevin Harvick (2001, 2014), Kyle Busch (2005, 2015), Joey Logano (2009, 2018), Chase Elliott (2016, 2020), and Kyle Larson (2014, 2021). Rod Osterlund Racing, Stacy Racing, and Richard Childress Racing (1981) 1981 would prove to be tumultuous for the defending Winston Cup champion. Sixteen races into the season, Rod Osterlund suddenly sold his team to Jim Stacy, an entrepreneur from Kentucky who entered NASCAR in 1977. After just four races, Earnhardt fell out with Stacy and left the team. Earnhardt finished out the year driving Pontiacs for Richard Childress Racing and managed to place seventh in the final points standings. Earnhardt departed RCR at the end of the season, citing a lack of chemistry. Earnhardt was also a color commentator for the Busch Clash, as David Hobbs was a pit reporter on that weekend. Bud Moore Engineering (1982–1983) The following year, at Childress's suggestion, Earnhardt joined car owner Bud Moore for the 1982 and 1983 seasons driving the No. 15 Wrangler Jeans-sponsored Ford Thunderbird (the only full-time Ford ride in his career). During the 1982 season, Earnhardt struggled. Although he won at Darlington, he failed to finish 18 of the 30 races and ended the season 12th in points, the worst of his career. He also suffered a broken kneecap at Pocono Raceway when he flipped after contact with Tim Richmond. In 1983, Earnhardt rebounded and won his first of 12 Twin 125 Daytona 500 qualifying races. He won at Nashville and at Talladega, finishing 8th in the points standings, despite failing to finish 13 of the 30 races. Return to Richard Childress Racing (1984–2001) 1984–1985 After the 1983 season, Earnhardt returned to Richard Childress Racing, replacing Ricky Rudd in the No. 3. Rudd went to Bud Moore's No. 15, replacing Earnhardt. Wrangler sponsored both drivers at their respective teams. During the 1984 and 1985 seasons, Earnhardt went to victory lane six times, at Talladega, Atlanta, Richmond, Bristol (twice), and Martinsville, where he finished fourth and eighth in the season standings respectively. 1986–1987 The 1986 season saw Earnhardt win his second career Winston Cup Championship and the first owner's championship for Richard Childress Racing. He won five races and had 16 top-fives and 23 top-10s. Earnhardt successfully defended his championship the following year, going to victory lane 11 times and winning the championship by 489 points over Bill Elliott. In the process, Earnhardt set a NASCAR modern-era record of four consecutive wins and won five of the first seven races. In the 1987 season, he earned the nickname "The Intimidator", due in part to the 1987 Winston All-Star Race. During this race, Earnhardt was briefly forced into the infield grass but kept control of his car and returned to the track without giving up his lead. The maneuver is now referred to as the "Pass in the Grass", even though Earnhardt did not pass anyone while he was off the track. After The Winston, an angry fan sent Bill France Jr. a letter threatening to kill Earnhardt at Pocono, Watkins Glen, or Dover, prompting the FBI to provide security for Earnhardt on the three tracks. The investigation was closed after the races at the three tracks finished without incident. 1988–1989 The 1988 season saw Earnhardt racing with a new sponsor, GM Goodwrench, after Wrangler Jeans dropped its sponsorship in 1987. During this season, he changed the color of his paint scheme from blue and yellow to the signature black in which the No. 3 car was painted for the rest of his life. He won three races in 1988, finishing third in the points standings behind Bill Elliott in first and Rusty Wallace in second. The following year, Earnhardt won five races, but a late spin out at North Wilkesboro arguably cost him the 1989 championship, as Rusty Wallace edged him out for it by 12 points (Earnhardt won the final race, but Wallace finished 15th when needing to finish at least 18th to win). It was his first season for the GM Goodwrench Chevrolet Lumina. 1990–1995 The 1990 season started for Earnhardt with victories in the Busch Clash and his heat of the Gatorade Twin 125's. Near the end of the Daytona 500, he had a dominant forty-second lead when the final caution flag came out with a handful of laps to go. When the green flag waved, Earnhardt was leading Derrike Cope. On the final lap, Earnhardt ran over a piece of metal, which was later revealed as a bell housing, in turn 3, cutting down a tire. Cope, in an upset, won the race while Earnhardt finished fifth after leading 155 of the 200 laps. The No. 3 Goodwrench-sponsored Chevy team took the flat tire that cost them the win and hung it on the shop wall as a reminder of how close they had come to winning the Daytona 500. Earnhardt won nine races that season and won his fourth Winston Cup title, beating Mark Martin by 26 points. He also became the first multiple winner of the annual all-star race, The Winston. The 1991 season saw Earnhardt win his fifth Winston Cup championship. This season, he scored four wins and won the championship by 195 points over Ricky Rudd. One of his wins came at North Wilkesboro, in a race where Harry Gant had a chance to set a single-season record by winning his fifth consecutive race, breaking a record held by Earnhardt. Late in the race, Gant lost his brakes, which gave Earnhardt the chance he needed to make the pass for the win and maintain his record. Earnhardt's only win of the 1992 season came at Charlotte, in the Coca-Cola 600, ending a 13-race win streak by Ford teams. Earnhardt finished a career-low 12th in the points for the second time in his career, with three last place finishes (Daytona and Talladega in July and Martinsville in September), and the only time he had finished that low since joining Richard Childress Racing. He still made the trip to the annual Awards Banquet with Rusty Wallace but did not have the best seat in the house. Wallace stated he and Earnhardt had to sit on the backs of their chairs to see, and Earnhardt said, "This sucks, I should have gone hunting." At the end of the year, longtime crew chief Kirk Shelmerdine left to become a driver. Andy Petree took over as crew chief. Hiring Petree turned out to be beneficial, as Earnhardt returned to the front in 1993. He once again came close to a win at the Daytona 500 and dominated Speedweeks before finishing second to Dale Jarrett on a last-lap pass. Earnhardt scored six wins en route to his sixth Winston Cup title, including wins in the first prime-time Coca-Cola 600 and The Winston, both at Charlotte, and the Pepsi 400 at Daytona. He beat Rusty Wallace for the championship by 80 points. On November 14, 1993, after the season-ending Hooters 500 at Atlanta, the race winner Wallace and 1993 series champion Earnhardt ran a dual Polish Victory Lap together while carrying #28 and #7 flags commemorating 1992 Daytona 500 winner Davey Allison and 1992 NASCAR Winston Cup Series champion Alan Kulwicki respectively, who both had died in separate plane accidents during the season. In 1994, Earnhardt achieved a feat that he himself had believed to be impossible—he scored his seventh Winston Cup championship, tying Richard Petty. He was very consistent, scoring four wins, and after Ernie Irvan was sidelined due to a near-deadly crash at Michigan (the two were neck-and-neck at the top of the points up until the crash), won the title by over 400 points over Mark Martin. Earnhardt sealed the deal at Rockingham by winning the race over Rick Mast. It was his final NASCAR championship and his final season for the GM Goodwrench Chevrolet Lumina. Earnhardt started off the 1995 season by finishing second in the Daytona 500 to Sterling Marlin. He won five races in 1995, including his first road course victory at Sears Point. He also won the Brickyard 400 at Indianapolis Motor Speedway, a win he called the biggest of his career. But in the end, Earnhardt lost the championship to Jeff Gordon by 34 points. The GM Goodwrench racing team changed to Chevrolet Monte Carlos. 1996–1999 1996 for Earnhardt started just like it had done in 1993—he dominated Speedweeks, only to finish second in the Daytona 500 to Dale Jarrett for the second time. He won early in the year, scoring consecutive victories at Rockingham and Atlanta. On July 28 in the DieHard 500 at Talladega, he was second in points and looking for his eighth season title, despite the departure of crew chief Andy Petree. Late in the race, Ernie Irvan lost control of his No. 28 Havoline-sponsored Ford Thunderbird, made contact with the No. 4 Kodak-sponsored Chevy Monte Carlo of Sterling Marlin, and ignited a crash that saw Earnhardt's No. 3 Chevrolet hit the tri-oval wall nearly head-on at almost 200 mph. After hitting the wall, Earnhardt's car flipped and slid across the track, in front of race traffic. His car was hit in the roof and windshield. This accident, as well as a similar accident that led to the death of Russell Phillips at Charlotte, led NASCAR to mandate the "Earnhardt Bar", a metal brace located in the center of the windshield that reinforces the roof in case of a similar crash. This bar is also required in NASCAR-owned United SportsCar Racing and its predecessors for road racing. Rain delays had canceled the live telecast of the race, and most fans first learned of the accident during the night's sports newscasts. Video of the crash showed what appeared to be a fatal incident, but once medical workers arrived at the car, Earnhardt climbed out and waved to the crowd, refusing to be loaded onto a stretcher despite a broken collarbone, sternum, and shoulder blade. Although the incident looked like it would end his season early, Earnhardt refused to stay out of the car. The next week at Indianapolis, he started the race but exited the car on the first pit stop, allowing Mike Skinner to take the wheel. When asked, Earnhardt said that vacating the No. 3 car was the hardest thing he had ever done. The following weekend at Watkins Glen, he drove the No. 3 Goodwrench Chevrolet to the fastest time in qualifying, earning the "True Grit" pole. T-shirts emblazoned with Earnhardt's face were quickly printed up, brandishing the caption, "It Hurt So Good". Earnhardt led for most of the race and looked to have victory in hand, but fatigue took its toll and he ended up sixth behind race winner Geoff Bodine. Earnhardt did not win again in 1996 but still finished fourth in the standings behind Terry Labonte, Jeff Gordon, and Dale Jarrett, with 2 wins, 13 top fives, 17 top tens, and his last 2 career poles, with an average finish of 10.6. David Smith departed as crew chief of the No. 3 team and RCR at the end of the year for personal reasons, and he was replaced by Larry McReynolds. In 1997, Earnhardt went winless for only the second time in his career. The only (non-points) win came during Speedweeks at Daytona in the Twin 125-mile qualifying race, his record eighth-straight win in the event. Once again in the hunt for the Daytona 500 with 10 laps to go, Earnhardt was taken out of contention by a late crash which sent his car upside down on the backstretch. He hit the low point of his year when he blacked out early in the Mountain Dew Southern 500 at Darlington in September, causing him to hit the wall. Afterward, he was disoriented, and it took several laps before he could find his pit stall. When asked, Earnhardt complained of double vision which made it difficult to pit. Mike Dillon (Richard Childress's son-in-law) was brought in to relieve Earnhardt for the remainder of the race. Earnhardt was evaluated at a local hospital and cleared to race the next week, but the cause of the blackout and double vision was never determined. Despite no wins, Earnhardt finished the season fifth in the final standings with 7 top fives and 16 top tens, with an average finish of 12.1. On February 15, 1998, Earnhardt finally won the Daytona 500 in his 20th attempt after failing to win in his previous 19 attempts. He began the season by winning his Twin 125-mile qualifier race for the ninth straight year, and the week before was the first to drive around the track under the newly installed lights, for coincidentally 20 laps. On race day, he showed himself to be a contender early. Halfway through the race, however, it seemed that Jeff Gordon had the upper hand. But by lap 138, Earnhardt had taken the lead and thanks to a push by teammate Mike Skinner, he maintained it. Earnhardt made it to the caution-checkered flag before Bobby Labonte. Afterwards, there was a large show of respect for Earnhardt, in which every crew member of every team lined pit road to shake his hand as he made his way to victory lane. Earnhardt then drove his No. 3 into the infield grass, starting a trend of post-race celebrations. He spun the car twice, throwing grass and leaving tire tracks in the shape of a No. 3 in the grass. He then spoke about the victory, saying, "I have had a lot of great fans and people behind me all through the years and I just can't thank them enough. The Daytona 500 is ours. We won it, we won it, we won it!" The rest of the season did not go as well, and the Daytona 500 was his only victory that year. Despite that, he did almost pull off a Daytona sweep, where he was one of the contenders for the win in the first nighttime Pepsi 400, but a pit stop late in the race in which a rogue tire cost him the race win. He slipped to 12th in the point standings halfway through the season, and Richard Childress decided to make a crew chief change, taking Mike Skinner's crew chief Kevin Hamlin and putting him with Earnhardt while giving Skinner Larry McReynolds (Earnhardt's crew chief). Earnhardt finished the 1998 season eighth in the final points standings, with 1 win, 5 top fives, and 13 top tens, with an average finish of 16.2. Before the 1999 season, fans began discussing Earnhardt's age and speculating that with his son, Dale Jr., making his Winston Cup debut, Earnhardt might be contemplating retirement. Earnhardt swept both races for the year at Talladega, leading some to conclude that his talent had become limited to the restrictor plate tracks, which require a unique skill set and an exceptionally powerful racecar to win. But halfway through the year, Earnhardt began to show some of the old spark. In the August race at Michigan, he led laps late in the race and nearly pulled off his first win on a non-restrictor-plate track since 1996. One week later, he provided NASCAR with one of its most controversial moments. At the Bristol night race, Earnhardt found himself in contention to win his first short track race since Martinsville in 1995. When a caution came out with 15 laps to go, leader Terry Labonte got hit from behind by the lapped car of Darrell Waltrip. His spin put Earnhardt in the lead with five cars between him and Labonte with five laps to go. Labonte had four fresh tires, and Earnhardt was driving on old tires, which made Earnhardt's car considerably slower. Labonte caught Earnhardt and passed him coming to the white flag, but Earnhardt drove hard into turn two, bumping Labonte and spinning him around. Earnhardt collected the win while spectators booed and made obscene gestures. "I didn't mean to turn him around, I just wanted to rattle his cage," Earnhardt said of the incident. He finished seventh in the standings that year, with 3 wins, 7 top fives, and 21 top tens, with an average finish of 12.0. 2000 In the 2000 season, Earnhardt had a resurgence, which was commonly attributed to neck surgery he underwent to correct a lingering injury from his 1996 Talladega crash. He scored what were considered the two most exciting wins of the year—winning by 0.010 |
Chronicles of the Imperium (2000): Last Unicorn Games. Delayed by legal issues and then a corporate buyout of Last Unicorn by Wizards of the Coast, a "Limited Edition" run of 3000 copies of a core rule-book was initially published, pending Wizard of the Coast's conversion of the game to its d20 role-playing game system and a subsequent wider release. The game was later discontinued, but was eventually published by Wizards of the Coast after the acquisition. Val Mayerik did interior art for the game. Dune: A Dream Of Rain (2004): Evil Twin Games; unlicensed fan-made game, based on the d20 System. Dune: Adventures in the Imperium (2021): Modiphius Entertainment. Its release coincided with the 2021 Dune film. Video games To date, there have been five licensed Dune-related video games released. There have also been many Dune-based MUDs (Multi-User Dimension) and browser-based online games, all created and run by fans. Dune (1992) 1992's Dune from Cryo Interactive/Virgin Interactive blends adventure with strategy. Loosely following the story of the 1965 novel Dune and using many visual elements from the 1984 film of the same name by David Lynch, the game casts the player as Paul Atreides, with the ultimate goal of driving the Harkonnens from the planet Dune and taking control of its valuable export, the spice. Key to success is the management of spice mining, military forces, and ecology as the player amasses allies and skills. One aspect of the game allows the player to terraform Arrakis from a desert into a fertile and green planet, at the cost of sandworm habitat and reduced melange spice production. Dune II (1992) Dune II: The Building of a Dynasty, later retitled Dune II: Battle for Arrakis for the Mega Drive/Genesis port, was released in December 1992 from Westwood Studios/Virgin Interactive. Often considered | 2000 features an enhanced storyline and functionality. Emperor: Battle for Dune (2001) Emperor: Battle for Dune (Intelligent Games/Westwood Studios/Electronic Arts) was released on June 12, 2001. A sequel to Dune 2000, the real-time strategy game features 3D graphics and live-action cutscenes, and casts players as Atreides, Harkonnens, or Ordos. Frank Herbert's Dune (2001) Released in 2001 by Cryo Interactive/DreamCatcher Interactive, Frank Herbert's Dune is a 3D video game based on the 2000 Sci Fi Channel miniseries of the same name. As Paul Muad'Dib Atreides, the player must become leader of the Fremen, seize control of Dune, and defeat the evil Baron Harkonnen. The game was not a commercial or critical success, and Cryo subsequently filed for bankruptcy in July 2002. Dune Generations (2001, cancelled) In 2001, Cryonetworks disclosed information about Dune Generations, an online, 3D real-time strategy game set in the Dune universe. An official website for the upcoming game featured concept images, a brief background story and description of the persistent gameworld, and a list of frequently asked questions. The game would be constructed using Cryo's own online multimedia development framework SCOL. Within "the infrastructure of a permanent and massive multiplayer world that exists online", Dune Generations would let players assume control of a dynasty in the Dune universe, with the goal of first mastering the natural resources of their own homeworlds and ultimately rising in power and influence through conflicts and alliances with other player dynasties. Each of the three available dynasty types - traders, soldiers, or mercenaries - would provide a different playing experience, all with the long-term goal of gaining control of Arrakis and its valuable spice. A preview video trailer was released in November 2001. The game was still in the alpha testing stage in February 2002, and the project was ultimately halted after |

plan to assure Feyd's power is to install him as ruler of Arrakis after a period of tyrannical misrule by Rabban, making Feyd appear to be the savior of the people. However, a crisis on Arrakis begins when the mysterious Muad'Dib emerges as a leader of the native Fremen tribes, uniting them against the rule of the Harkonnens. Eventually, a series of Fremen victories against Beast Rabban threaten to disrupt the trade of the spice, inciting the Padishah Emperor Shaddam IV to intervene personally, leading several legions of Sardaukar. After the emperor's arrival on Arrakis, both Corrino and Harkonnen are shocked to learn that rather than a native Fremen warlord, their opponent Muad'Dib is the still-living Paul Atreides, and the Emperor's intervention was part of his plan. The Imperial forces fall prey to a surprise attack by the Fremen, who let a sandstorm short out the force field shields of the transport ships, disable them with projectile weapons, and then mount a mass assault using sandworms as siege-breakers. Their enemies are left trapped on the planet, outnumbered by the many tribes and outgunned by the sandworms. The Harkonnen's past ruthlessness further causes the enraged Fremen to give them little to no quarter; over the course of the battle their entire army is exterminated. The Harkonnen leadership are also all killed in the course of this battle. Rabban dies first, in the early stages of the battle. Baron Harkonnen himself is poisoned with a gom jabbar by Paul's sister Alia Atreides, still a toddler physically but an adult Reverend Mother mentally, who reveals that she is his granddaughter to him just before his death. His remaining heir Feyd-Rautha is killed in ritual combat by Paul Atreides. House Harkonnen as a political entity is left virtually defunct, permanently excluded from galactic power, though Harkonnen blood is technically ascendant, as Imperial House Atreides is composed entirely of Vladimir Harkonnen's descendants. Children of Dune Alia had been born with her ancestral memories in the womb, a circumstance the Bene Gesserit refer to as Abomination, because in their experience it is inevitable that the individual will become possessed by the personality of one of their ancestors. In Children of Dune, Alia falls victim to this prediction when she shares control of her body with the ego-memory of the Baron Harkonnen, and eventually falls under his power. Alia eventually commits suicide, realizing that Harkonnen's consciousness has surpassed her abilities to contain him. Prelude to Dune In the Prelude to Dune prequel series by Brian Herbert and Anderson, it is established that Baron Vladimir Harkonnen is the son and heir of Dmitri Harkonnen and his wife Victoria. Harkonnen's father had been the head of House Harkonnen and ruled the planet Giedi Prime. Trained since youth as a possible successor, Vladimir had been eventually chosen over his half-brother Abulurd (namesake of the original). Unhappy with his brother's doings, Abulurd eventually marries Emmi Rabban and renounces the family name and his rights to the title. Under the name Abulurd Rabban, he reigns as governor of the secondary Harkonnen planet Lankiveil. Abulurd and his wife have two sons: Glossu Rabban (later nicknamed "Beast Rabban" after he murders his own father) and Feyd-Rautha; Vladimir later adopts the boys back into House Harkonnen, and Feyd becomes his designated heir. The Baron's most prominent political rival is Duke Leto Atreides; the Harkonnens and the Atreides have been bitter enemies for millennia, since the Battle of Corrin that ended the Butlerian Jihad. When Emperor Shaddam IV orchestrates a plot to destroy the "Red Duke" Leto, the Baron eagerly lends his aid. The young Baron Vladimir Harkonnen is described as an exceedingly handsome man, possessing red hair and a near-perfect physique. The Bene Gesserit Reverend Mother Gaius Helen Mohiam is instructed by the Sisterhood to collect his genetic material (through conception) for their breeding program. As the Baron's homosexuality is something of an open secret, Mohiam blackmails him into having sexual relations with her and conceives his child. When that daughter proves genetically undesirable, Mohiam kills her and returns to Harkonnen for a second try; at this point he drugs and viciously rapes her. She exacts her retribution by infecting him with a rare, incurable disease that later causes his obesity. Mohiam's second child with the Baron is Jessica. In Dune: House Harkonnen, the deteriorating Baron at first walks with the assistance of a cane, then relies on belt-mounted suspensors to retain mobility. He consults numerous doctors in the expanse of time between the Dune: House Atreides and Dune: House Harkonnen, up to and including his future instrument Dr. Yueh, all of whom are ultimately no help. To conceal this debilitation, he pretends that his obesity is due to intentional overindulgence, lest the Landsraad remove him from power. When he determines that Mohiam inflicted him with the disease, he attempts to coerce her into revealing the cure, but soon discovers that there is none. The Baron, Duke Leto, and Jessica herself are unaware that Jessica is secretly the Baron's daughter or that he has even fathered one. In the year 10,176, the Baron's grandson Paul is born to Leto and Jessica. Hunters of Dune In Hunters of Dune (2006), the continuation of the original series by Brian Herbert and Kevin J. Anderson, the Baron is resurrected as a ghola (5,029 years after the death of Alia) by the Lost Tleilaxu Uxtal, acting on orders from the Face Dancer Khrone. Khrone intends to use the Baron ghola to manipulate a ghola of Paul Atreides, named Paolo. Khrone tries various torture techniques for three years to awaken the 12-year-old Baron's genetic memories; these methods fail due to the Baron's sadomasochistic nature. Khrone is successful when he imprisons the Baron in a sensory deprivation tank for a prolonged period; the Baron's memories of his former life return. The reincarnated Baron is soon haunted by the voice of Alia in his mind; the source of this inner Alia is never explained. In adaptations 1984 film Baron Harkonnen is portrayed by Kenneth McMillan in David Lynch's 1984 film. The obese and disheveled Baron is overtly unstable, and covered in oozing pustules. William Hughes of The A.V. Club deemed McMillan's facial prosthetics "very memorable". Emmet Asher-Perrin of Tor.com wrote that "Lynch's attempt is infamous for really leaning on [the] codified aspects of the Baron, to the point where his sore-ridden appearance has been called out as a likely connection to the AIDS epidemic, which was a prevalent health crisis while the film was in production." Travis Johnson of Flicks.com.au noted that the Lynch film embraced "the archetype of the depraved gay sadist", which would not be acceptable in 2019. Asher-Perrin added, "Lynch also makes a point of connecting the Baron's desire for men to deviancy and violence, deliberately juxtaposing his assault of a young man with a tender love scene between Duke Leto and Lady Jessica Atreides." 2000 miniseries Ian McNeice plays the Baron in the 2000 Sci-Fi Channel miniseries Frank Herbert's Dune, and its | is written as "a predatory homosexual given to pederasty and incest, an unrepentant rapist and murderer." The Baron's sexual preference for young men is implied in Dune and Children of Dune. It is noted, however, that he "once permitted himself to be seduced" by a Bene Gesserit in the liaison which produced his secret daughter. Plotlines Dune As Dune begins, a longstanding feud exists between the Harkonnens of Giedi Prime and the Atreides of Caladan. The Baron's intent to exterminate the Atreides line seems close to fruition as Duke Leto Atreides is lured to the desert planet Arrakis on the pretense of taking over the valuable melange operation there. The Baron has an agent in the Atreides household: Leto's own physician, the trusted Suk doctor Wellington Yueh. Though Suk Imperial Conditioning supposedly makes the subject incapable of inflicting harm, the Baron's twisted Mentat Piter De Vries notes: The Baron has taken Yueh's wife Wanna prisoner, threatening her with interminable torture unless Yueh complies with his demands. Harkonnen also distracts Leto's Mentat Thufir Hawat from discovering Yueh by guiding Hawat toward another suspect: Leto's Bene Gesserit concubine Lady Jessica, of whom Hawat is already distrustful. The Atreides are soon attacked by Harkonnen forces (secretly supplemented by the seemingly unstoppable Imperial Sardaukar) as Yueh disables the protective shields around the Atreides palace on Arrakis. As instructed, Yueh takes Leto prisoner; however, desiring to slay the Baron, Yueh provides the captive Leto with a fake tooth filled with poisonous gas as a means of simultaneous assassination and suicide. De Vries kills Yueh but he also dies with Leto in the assassination attempt; however Harkonnen survives. The Baron then manipulates Hawat into his service, by convincing Hawat that Lady Jessica was the traitor and using Hawat's desire for revenge on Lady Jessica and the Emperor as motivation to assist House Harkonnen. Jessica flees into the desert with her and Leto's son Paul Atreides, and both are presumed dead. Paul's prescience helps him determine the identity of Jessica's father, the "maternal grandfather who cannot be named" — the Baron himself. Over the next two years, Harkonnen learns that his nephews Glossu Rabban and Feyd-Rautha are conspiring against him to usurp his throne; he lets them continue to do so, reasoning that they have to somehow learn to organize a conspiracy. As punishment for a failed assassination attempt against him, Harkonnen forces Feyd to single-handedly slaughter all the female slaves who serve as Feyd's lovers. He explains that Feyd has to learn the price of failure. The Baron's plan to assure Feyd's power is to install him as ruler of Arrakis after a period of tyrannical misrule by Rabban, making Feyd appear to be the savior of the people. However, a crisis on Arrakis begins when the mysterious Muad'Dib emerges as a leader of the native Fremen tribes, uniting them against the rule of the Harkonnens. Eventually, a series of Fremen victories against Beast Rabban threaten to disrupt the trade of the spice, inciting the Padishah Emperor Shaddam IV to intervene personally, leading several legions of Sardaukar.

to guarantee Hawat's allegiance to the Harkonnens, who alone possess the antidote. De Vries is the architect of the plan to destroy House Atreides, longtime enemy of the Harkonnens, while restoring the Baron's stewardship over the planet Arrakis. Dr. Wellington Yueh, personal physician to House Atreides, has undergone Suk conditioning, which renders him incapable of inflicting harm on his patients. De Vries breaks this conditioning through torture and psychological manipulation, and Yueh eventually betrays House Atreides. De Vries originally plans to claim Lady Jessica, the concubine of Duke Leto Atreides, as his slave, but accepts an offer to become governor of Arrakis instead. However, Yueh has given the captured Leto a false tooth filled with poison gas. When Leto crushes the tooth, the intended victim Baron Harkonnen escapes, but Leto and De Vries die. Prelude to Dune In Dune: House Corrino (published in 2001 and the third novel in the Prelude to Dune prequel series by Brian Herbert and Kevin J. Anderson), Piter De Vries discovers the Harkonnen heritage of Lady Jessica and her newborn son Paul, and attempts to kidnap and ransom the infant. The plot is thwarted and the secret preserved—the Reverend Mother Gaius Helen Mohiam kills the Mentat and arranges for his corpse to be shipped home to Giedi Prime. An enraged Baron is left with no choice but to order a duplicate from the Bene Tleilax: the Mentat De Vries featured in Herbert's original novel Dune. In adaptations De Vries is portrayed by Brad Dourif in David Lynch's 1984 film Dune, Jan Unger in the 2000 Dune miniseries, and David Dastmalchian in Denis Villeneuve's 2021 film Dune.

first mixed colors (orange-tan and light-blue), but it would be difficult for this party to determine the final secret color (yellow-brown). Bringing the analogy back to a real-life exchange using large numbers rather than colors, this determination is computationally expensive. It is impossible to compute in a practical amount of time even for modern supercomputers. Cryptographic explanation The simplest and the original implementation of the protocol uses the multiplicative group of integers modulo p, where p is prime, and g is a primitive root modulo p. These two values are chosen in this way to ensure that the resulting shared secret can take on any value from 1 to p–1. Here is an example of the protocol, with non-secret values in blue, and secret values in red. Alice and Bob publicly agree to use a modulus p = 23 and base g = 5 (which is a primitive root modulo 23). Alice chooses a secret integer a = 4, then sends Bob A = ga mod p A = 54 mod 23 = 4 Bob chooses a secret integer b = 3, then sends Alice B = gb mod p B = 53 mod 23 = 10 Alice computes s = Ba mod p s = 104 mod 23 = 18 Bob computes s = Ab mod p s = 43 mod 23 = 18 Alice and Bob now share a secret (the number 18). Both Alice and Bob have arrived at the same values because under mod p, More specifically, Only a and b are kept secret. All the other values – p, g, ga mod p, and gb mod p – are sent in the clear. The strength of the scheme comes from the fact that gab mod p = gba mod p take extremely long times to compute by any known algorithm just from the knowledge of p, g, ga mod p, and gb mod p. Once Alice and Bob compute the shared secret they can use it as an encryption key, known only to them, for sending messages across the same open communications channel. Of course, much larger values of a, b, and p would be needed to make this example secure, since there are only 23 possible results of n mod 23. However, if p is a prime of at least 600 digits, then even the fastest modern computers using the fastest known algorithm cannot find a given only g, p and ga mod p. Such a problem is called the discrete logarithm problem. The computation of ga mod p is known as modular exponentiation and can be done efficiently even for large numbers. Note that g need not be large at all, and in practice is usually a small integer (like 2, 3, ...). Secrecy chart The chart below depicts who knows what, again with non-secret values in blue, and secret values in red. Here Eve is an eavesdropper – she watches what is sent between Alice and Bob, but she does not alter the contents of their communications. g = public (prime) base, known to Alice, Bob, and Eve. g = 5 p = public (prime) modulus, known to Alice, Bob, and Eve. p = 23 a = Alice's private key, known only to Alice. a = 6 b = Bob's private key known only to Bob. b = 15 A = Alice's public key, known to Alice, Bob, and Eve. A = ga mod p = 8 B = Bob's public key, known to Alice, Bob, and Eve. B = gb mod p = 19 Now s is the shared secret key and it is known to both Alice and Bob, but not to Eve. Note that it is not helpful for Eve to compute AB, which equals ga + b mod p. Note: It should be difficult for Alice to solve for Bob's private key or for Bob to solve for Alice's private key. If it is not difficult for Alice to solve for Bob's private key (or vice versa), Eve may simply substitute her own private / public key pair, plug Bob's public key into her private key, produce a fake shared secret key, and solve for Bob's private key (and use that to solve for the shared secret key. Eve may attempt to choose a public / private key pair that will make it easy for her to solve for Bob's private key). Another demonstration of Diffie–Hellman (also using numbers too small for practical use) is given here. Generalization to finite cyclic groups Here is a more general description of the protocol: Alice and Bob agree on a finite cyclic group G of order n and a generating element g in G. (This is usually done long before the rest of the protocol; g is assumed to be known by all attackers.) The group G is written multiplicatively. Alice picks a random natural number a with 1 < a < n, and sends the element ga of G to Bob. Bob picks a random natural number b with 1 < b < n, and sends the element gb of G to Alice. Alice computes the element (gb)a = gba of G. Bob computes the element (ga)b = gab of G. Both Alice and Bob are now in possession of the group element gab = gba, which can serve as the shared secret key. The group G satisfies the requisite condition for secure communication if there is not an efficient algorithm for determining gab given g, ga, and gb. For example, the elliptic curve Diffie–Hellman protocol is a variant that represents an element of G as a point on an elliptic curve instead of as an integer modulo n. Variants using hyperelliptic curves have also been proposed. The supersingular isogeny key exchange is a Diffie–Hellman variant that has been designed to be secure against quantum computers. Ephemeral and/or Static Keys The used keys can either be ephemeral or static (long term) key, but could even be mixed, so called semi-static DH. These variants have different properties and hence different use cases. An overview over many variants and some also discussions can for example be found in NIST SP 800-56A. Here just a basic list: ephemeral, ephemeral: Usually used for key agreement. Provides forward secrecy, but no authenticity. static, static: Would generate a long term shared secret. Does not provide forward secrecy, but implicit authenticity. Since the keys are static it would for example not protect against replay-attacks. ephemeral, static: For example used in ElGamal encryption or Integrated Encryption Scheme (IES). If used in key agreement it could provide implicit one-sided authenticity (the ephemeral side could verify the authenticity of the static side). No forward secrecy is provided. It is possible to use ephemeral and static keys in one key agreement to provide more security as for example shown in NIST SP 800-56A, but it is also possible to combine those in a single DH key exchange, which is then called triple DH (3-DH). Triple Diffie-Hellman (3-DH) In 1997 a kind of double DH was proposed by Simon Blake-Wilson, Don Johnson, Alfred Menezes in "Key Agreement Protocols and their Security Analysis (1997)", which was improved by C. Kudla and K. G. Paterson in “Modular Security Proofs for Key Agreement Protocols (2005)” and shown to be secure. It's also used or mentioned in other variants. For example: Extended Triple Diffie-Hellman sci.crypt news group (from 18.08.2002) Double Ratchet Algorithm Signal Protocol The long term secret keys of Alice and Bob are denoted by a and b respectively, with public keys A and B, as well as the ephemeral key pairs x, X and y, Y. Then protocol is: The long term public keys need to be transferred somehow. That can be done beforehand in a separate, trusted channel, or the public keys can be encrypted using some partial key agreement to preserve anonymity. For more of such details as well as other improvements like side channel protection or explicit key confirmation, as well as early messages and additional password authentication, one could e.g. have a look at "Advanced modular handshake for key agreement and optional authentication" Operation with more than two parties Diffie–Hellman key agreement is | static (long term) key, but could even be mixed, so called semi-static DH. These variants have different properties and hence different use cases. An overview over many variants and some also discussions can for example be found in NIST SP 800-56A.

For more of such details as well as other improvements like side channel protection or explicit key confirmation, as well as early messages and additional password authentication, one could e.g. have a look at "Advanced modular handshake for key agreement and optional authentication" Operation with more than two parties Diffie–Hellman key agreement is not limited to negotiating a key shared by only two participants. Any number of users can take part in an agreement by performing iterations of the agreement protocol and exchanging intermediate data (which does not itself need to be kept secret). For example, Alice, Bob, and Carol could participate in a Diffie–Hellman agreement as follows, with all operations taken to be modulo p: The parties agree on the algorithm parameters p and g. The parties generate their private keys, named a, b, and c. Alice computes and sends it to Bob. Bob computes () = and sends it to Carol. Carol computes () = and uses it as her secret. Bob computes gb and sends it to Carol. Carol computes () = and sends it to Alice. Alice computes () = = and uses it as her secret. Carol computes and sends it to Alice. Alice computes () = and sends it to Bob. Bob computes () = = and uses it as his secret. An eavesdropper has been able to see , , , , , and , but cannot use any combination of these to efficiently reproduce . To extend this mechanism to larger groups, two basic principles must be followed: Starting with an "empty" key consisting only of g, the secret is made by raising the current value to every participant's private exponent once, in any order (the first such exponentiation yields the participant's own public key). Any intermediate value (having up to N-1 exponents applied, where N is the number of participants in the group) may be revealed publicly, but the final value (having had all N exponents applied) constitutes the shared secret and hence must never be revealed publicly. Thus, each user must obtain their copy of the secret by applying their own private key last (otherwise there would be no way for the last contributor to communicate the final key to its recipient, as that last contributor would have turned the key into the very secret the group wished to protect). These principles leave open various options for choosing in which order participants contribute to keys. The simplest and most obvious solution is to arrange the N participants in a circle and have N keys rotate around the circle, until eventually every key has been contributed to by all N participants (ending with its owner) and each participant has contributed to N keys (ending with their own). However, this requires that every participant perform N modular exponentiations. By choosing a more optimal order, and relying on the fact that keys can be duplicated, it is possible to reduce the number of modular exponentiations performed by each participant to using a divide-and-conquer-style approach, given here for eight participants: Participants A, B, C, and D each perform one exponentiation, yielding ; this value is sent to E, F, G, and H. In return, participants A, B, C, and D receive . Participants A and B each perform one exponentiation, yielding , which they send to C and D, while C and D do the same, yielding , which they send to A and B. Participant A performs an exponentiation, yielding , which it sends to B; similarly, B sends to A. C and D do similarly. Participant A performs one final exponentiation, yielding the secret = , while B does the same to get = ; again, C and D do similarly. Participants E through H simultaneously perform the same operations using as their starting point. Once this operation has been completed all participants will possess the secret , but each participant will have performed only four modular exponentiations, rather than the eight implied by a simple circular arrangement. Security The protocol is considered secure against eavesdroppers if G and g are chosen properly. In particular, the order of the group G must be large, particularly if the same group is used for large amounts of traffic. The eavesdropper has to solve the Diffie–Hellman problem to obtain gab. This is currently considered difficult for groups whose order is large enough. An efficient algorithm to solve the discrete logarithm problem would make it easy to compute a or b and solve the Diffie–Hellman problem, making this and many other public key cryptosystems insecure. Fields of small characteristic may be less secure. The order of G should have a large prime factor to prevent use of the Pohlig–Hellman algorithm to obtain a or b. For this reason, a Sophie Germain prime q is sometimes used to calculate , called a safe prime, since the order of G is then only divisible by 2 and q. g is then sometimes chosen to generate the order q subgroup of G, rather than G, so that the Legendre symbol of ga never reveals the low order bit of a. A protocol using such a choice is for example IKEv2. g is often a small integer such as 2. Because of the random self-reducibility of the discrete logarithm problem a small g is equally secure as any other generator of the same group. If Alice and Bob use random number generators whose outputs are not completely random and can be predicted to some extent, then it is much easier to eavesdrop. In the original description, the Diffie–Hellman exchange by itself does not provide authentication of the communicating parties and is thus vulnerable to a man-in-the-middle attack. Mallory (an active attacker executing the man-in-the-middle attack) may establish two distinct key exchanges, one with Alice and the other with Bob, effectively masquerading as Alice to Bob, and vice versa, allowing her to decrypt, then re-encrypt, the messages passed between them. Note that Mallory must continue to be in the middle, actively decrypting and re-encrypting messages every time Alice and Bob communicate. If she is ever absent, her previous presence is then revealed to Alice and Bob. They will know that all of their private conversations had been intercepted and decoded by someone in the channel. In most cases it will not help them get Mallory's private key, even if she used the same key for both exchanges. A method to authenticate the communicating parties to each other is generally needed to |
Dimsdale, as the new sheriff, assuming that he will be easy to control and manipulate. However, Dimsdale, a deputy under the famous lawman Tom Destry, promptly swears off drinking, and is able to call upon the latter's equally formidable son, Tom Destry Jr., to help him make Bottleneck a lawful, respectable town. Destry arrives in Bottleneck with Jack Tyndall, a cattleman, and his sister, Janice. Destry initially confounds the townsfolk by refusing to strap on a gun and maintaining civility in dealing with everyone, including Kent and Frenchy. This quickly makes him a disappointment to Dimsdale and a laughingstock to the townspeople; he is mockingly asked to "clean up" Bottleneck by being given a mop and bucket. However, after a number of rowdy horsemen ride into town shooting their pistols in the air, he demonstrates uncanny expertise in marksmanship and threatens to jail them if they do it again, earning the respect of Bottleneck's citizens. Through the townsmen's evasive answers regarding the whereabouts of Keogh, Destry gradually begins to suspect that Keogh was murdered. He confirms this by provoking Frenchy into admitting it, but without a location for the body, he lacks any proof. Destry therefore deputizes Boris, a Russian immigrant whom Frenchy had earlier humiliated, and implies to Kent that he had found the body outside of town "in remarkably good condition". When Kent sends a member of his gang to check on Keogh's burial site, Boris and Dimsdale follow, capture, and jail him. Although the gang member is charged with Keogh's murder (in the hope that he would implicate Kent in exchange for clemency), Mayor Slade appoints himself judge of the trial, making an innocent verdict a foregone conclusion. To prevent this, Destry calls in a judge from a larger city in secret, but the plan is ruined after Boris accidentally gives away the other judge's name in the saloon. Kent orders Frenchy to invite the deputy to her house while other gang members storm the sheriff's office and cause a breakout; now in love with Destry, she accepts. When shots are fired, he rushes back, to find the cell empty and Dimsdale mortally wounded. Destry returns to his room and puts on his gun belt, abandoning his previous commitment to nonviolence. Under Destry's command, the honest townsmen form a posse and prepare to attack the saloon, where Kent's gang is fortified, while Destry enters through the roof and looks for Kent. At Frenchy's urging, the townswomen march in between the groups, preventing further violence, before breaking into the saloon and subduing the gang. Kent narrowly escapes, and attempts to shoot Destry from the second floor; Frenchy takes the bullet for him, killing her, and Destry kills Kent. Some time later, Destry is shown to be the sheriff of a now lawful Bottleneck, repeating to children the stories that Dimsdale told him of the town's violent history. He jokingly tells a story about marriage to Janice, implying a marriage between them will soon follow.

Production Western writer Max Brand contributed the novel, Destry Rides Again, but the film also owes its origins to Brand's serial "Twelve Peers", published in a pulp magazine. In the original work, Harrison (or "Harry") Destry was not a pacifist. As filmed in 1932, with Tom Mix in the starring role, the central character differed in that Destry did wear six-guns. The film was James Stewart's first Western (he would not return to the genre until 1950, with Winchester '73, followed by Broken Arrow).

function, this is true. However, in 1872 Weierstrass found the first example of a function that is continuous everywhere but differentiable nowhere. This example is now known as the Weierstrass function. In 1931, Stefan Banach proved that the set of functions that have a derivative at some point is a meager set in the space of all continuous functions. Informally, this means that hardly any random continuous functions have a derivative at even one point. Derivative as a function Let be a function that has a derivative at every point in its domain. We can then define a function that maps every point to the value of the derivative of at . This function is written and is called the derivative function or the derivative of . Sometimes has a derivative at most, but not all, points of its domain. The function whose value at equals whenever is defined and elsewhere is undefined is also called the derivative of . It is still a function, but its domain is strictly smaller than the domain of . Using this idea, differentiation becomes a function of functions: The derivative is an operator whose domain is the set of all functions that have derivatives at every point of their domain and whose range is a set of functions. If we denote this operator by , then is the function . Since is a function, it can be evaluated at a point . By the definition of the derivative function, . For comparison, consider the doubling function given by ; is a real-valued function of a real number, meaning that it takes numbers as inputs and has numbers as outputs: The operator , however, is not defined on individual numbers. It is only defined on functions: Because the output of is a function, the output of can be evaluated at a point. For instance, when is applied to the square function, , outputs the doubling function , which we named . This output function can then be evaluated to get , , and so on. Higher derivatives Let be a differentiable function, and let be its derivative. The derivative of (if it has one) is written and is called the second derivative of . Similarly, the derivative of the second derivative, if it exists, is written and is called the third derivative of . Continuing this process, one can define, if it exists, the th derivative as the derivative of the th derivative. These repeated derivatives are called higher-order derivatives. The th derivative is also called the derivative of order and denoted . If represents the position of an object at time , then the higher-order derivatives of have specific interpretations in physics. The first derivative of is the object's velocity. The second derivative of is the acceleration. The third derivative of is the jerk. And finally, the fourth through sixth derivatives of are snap, crackle, and pop; most applicable to astrophysics. A function need not have a derivative (for example, if it is not continuous). Similarly, even if does have a derivative, it may not have a second derivative. For example, let Calculation shows that is a differentiable function whose derivative at is given by {{math|f(x)}} is twice the absolute value function at , and it does not have a derivative at zero. Similar examples show that a function can have a th derivative for each non-negative integer but not a th derivative. A function that has successive derivatives is called times differentiable. If in addition the th derivative is continuous, then the function is said to be of differentiability class . (This is a stronger condition than having derivatives, as shown by the second example of .) A function that has infinitely many derivatives is called infinitely differentiable or smooth. On the real line, every polynomial function is infinitely differentiable. By standard differentiation rules, if a polynomial of degree is differentiated times, then it becomes a constant function. All of its subsequent derivatives are identically zero. In particular, they exist, so polynomials are smooth functions. The derivatives of a function at a point provide polynomial approximations to that function near . For example, if is twice differentiable, then in the sense that If is infinitely differentiable, then this is the beginning of the Taylor series for evaluated at around . Inflection point A point where the second derivative of a function changes sign is called an inflection point. At an inflection point, the second derivative may be zero, as in the case of the inflection point of the function given by , or it may fail to exist, as in the case of the inflection point of the function given by . At an inflection point, a function switches from being a convex function to being a concave function or vice versa. Notation (details) Leibniz's notation The symbols , , and were introduced by Gottfried Wilhelm Leibniz in 1675. It is still commonly used when the equation is viewed as a functional relationship between dependent and independent variables. Then the first derivative is denoted by and was once thought of as an infinitesimal quotient. Higher derivatives are expressed using the notation for the nth derivative of . These are abbreviations for multiple applications of the derivative operator. For example, With Leibniz's notation, we can write the derivative of at the point in two different ways: Leibniz's notation allows one to specify the variable for differentiation (in the denominator), which is relevant in partial differentiation. It also can be used to write the chain rule as Lagrange's notation Sometimes referred to as prime notation, one of the most common modern notations for differentiation is due to Joseph-Louis Lagrange and uses the prime mark, so that the derivative of a function is denoted . Similarly, the second and third derivatives are denoted and To denote the number of derivatives beyond this point, some authors use Roman numerals in superscript, whereas others place the number in parentheses: or The latter notation generalizes to yield the notation for the nth derivative of – this notation is most useful when we wish to talk about the derivative as being a function itself, as in this case the Leibniz notation can become cumbersome. Newton's notation Newton's notation for differentiation, also called the dot notation, places a dot over the function name to represent a time derivative. If , then and denote, respectively, the first and second derivatives of . This notation is used exclusively for derivatives with respect to time or arc length. It is typically used in differential equations in physics and differential geometry. The dot notation, however, becomes unmanageable for high-order derivatives (order 4 or more) and cannot deal with multiple independent variables. Euler's notation Euler's notation uses a differential operator , which is applied to a function to give the first derivative . The nth derivative is denoted . If is a dependent variable, then often the subscript x is attached to the D to clarify the independent variable x. Euler's notation is then written or , although this subscript is often omitted when the variable x is understood, for instance when this is the only independent variable present in the expression. Euler's notation is useful for stating and solving linear differential equations. Rules of computation The derivative of a function can, in principle, be computed from the definition by considering the difference quotient, and computing its limit. In practice, once the derivatives of a few simple functions are known, the derivatives of other functions are more easily computed using rules for obtaining derivatives of more complicated functions from simpler ones. Rules for basic functions Here are the rules for the derivatives of the most common basic functions, where a is a real number. Derivatives of powers: Exponential and logarithmic functions: Trigonometric functions: Inverse trigonometric functions: Rules for combined functions Here are some of the most basic rules for deducing the derivative of a compound function from derivatives of basic functions. Constant rule: if f(x) is constant, then Sum rule: for all functions f and g and all real numbers and . Product rule: for all functions f and g. As a special case, this rule includes the fact whenever is a constant, because by the constant rule. Quotient rule: for all functions f and g at all inputs where . Chain rule for composite functions: If , then Computation example The derivative of the function given by is Here the second term was computed using the chain rule and third using the product rule. The known derivatives of the elementary functions x2, x4, sin(x), ln(x) and , as well as the constant 7, were also used. Definition with hyperreals Relative to a hyperreal extension of the real numbers, the derivative of a real function at a real point can be defined as the shadow of the quotient for infinitesimal , where . Here the natural extension of to the hyperreals is still denoted . Here the derivative is said to exist if the shadow is independent of the infinitesimal chosen. In higher dimensions Vector-valued functions A vector-valued function y of a real variable sends real numbers to vectors in some vector space Rn. A vector-valued function can be split up into its coordinate functions , meaning that . This includes, for example, parametric curves in R2 or R3. The coordinate functions are real valued functions, so the above definition of derivative applies to them. The derivative of y(t) is defined to be the vector, called the tangent vector, whose coordinates are the derivatives of the coordinate functions. That is, Equivalently, if the limit exists. The subtraction in the numerator is the subtraction of vectors, not scalars. If the derivative of y exists for every value of t, then y′ is another vector-valued function. If is the standard basis for Rn, then y(t) can also be written as . If we assume that the derivative of a vector-valued function retains the linearity property, then the derivative of y(t) must be because each of the basis vectors is a constant. This generalization is useful, for example, if y(t) is the position vector of a particle at time t; then the derivative y′(t) is the velocity vector of the particle at time t. Partial derivatives Suppose that f is a function that depends on more than one variable—for instance, f can be reinterpreted as a family of functions of one variable indexed by the other variables: In other words, every value of x chooses a function, denoted fx, which is a function of one real number. That is, Once a value of x is chosen, say a, then determines a function fa that sends y to : In this expression, a is a constant, not a variable, so fa is a function of only one real variable. Consequently, the definition of the derivative for a function of one variable applies: The above procedure can be performed for any choice of a. Assembling the derivatives together into a function gives a function that describes the variation of f in the y direction: This is the partial derivative of f with respect to y. Here ∂ is a rounded d called the partial derivative symbol. To distinguish it from the letter d, ∂ is sometimes pronounced "der", "del", or "partial" instead of "dee". In general, the partial derivative of a function in the direction xi at the point (a1, ..., an) is defined to be: In the above difference quotient, all the variables except xi are held fixed. That choice of fixed values determines a function of one variable and, by definition, In other words, the different choices of a index a family of one-variable functions just as in the example above. This expression also shows that the computation of partial derivatives reduces to the computation of one-variable derivatives. This is fundamental for the study of the functions of several real variables. Let be such a real-valued function. If all partial derivatives of are defined at the point , these partial derivatives define the vector which is called the gradient of at . If is differentiable at every point in some domain, then the gradient is a vector-valued function that maps the point to the vector . Consequently, the gradient determines a vector field. Directional derivatives If f is a real-valued function on Rn, then the partial derivatives of f measure its variation in the direction of the coordinate axes. For example, if f is a function of x and y, then its partial derivatives measure the variation in f in the x direction and the y direction. They do not, however, directly measure the variation of f in any other direction, such as along the diagonal line . These are measured using directional derivatives. Choose a vector The directional derivative of f in the direction of v at the point x is the limit In some cases it may be easier to compute or estimate the directional derivative after changing the length of the vector. Often this is done to turn the problem into the computation of a directional derivative in the direction of a unit vector. To see how this works, suppose that where u is a unit vector in the direction of v. Substitute into the difference quotient. The difference quotient becomes: This is λ times the difference quotient for the directional derivative of f with respect to u. Furthermore, taking the limit as h tends to zero is the same as taking the limit as k tends to zero because h and k are multiples of each other. Therefore, . Because of this rescaling property, directional derivatives are frequently considered only for unit vectors. If all the partial derivatives of f exist and are continuous at x, then they determine the directional derivative of f in the direction v by the formula: This is a consequence of the definition of the total derivative. It follows that the directional derivative is linear in v, meaning that . The same definition also works when f is a function with values in Rm. The above definition is applied to each component of the vectors. In this case, the directional derivative is a vector in Rm. Total derivative, total differential and Jacobian matrix When f is a function from an open subset of Rn to Rm, then the directional derivative of f in a chosen direction is the best linear approximation to f at that point and in that direction. But when , no single directional derivative can give a complete picture of the behavior of f. The total derivative gives a complete picture by considering all directions at once. | The idea, illustrated by Figures 1 to 3, is to compute the rate of change as the limit value of the ratio of the differences as tends towards 0. Toward a definition The most common approach to turn this intuitive idea into a precise definition is to define the derivative as a limit of difference quotients of real numbers. This is the approach described below. Let be a real valued function defined in an open neighborhood of a real number . In classical geometry, the tangent line to the graph of the function at was the unique line through the point that did not meet the graph of transversally, meaning that the line did not pass straight through the graph. The derivative of with respect to at is, geometrically, the slope of the tangent line to the graph of at . The slope of the tangent line is very close to the slope of the line through and a nearby point on the graph, for example . These lines are called secant lines. A value of close to zero gives a good approximation to the slope of the tangent line, and smaller values (in absolute value) of will, in general, give better approximations. The slope of the secant line is the difference between the values of these points divided by the difference between the values, that is, This expression is Newton's difference quotient. Passing from an approximation to an exact answer is done using a limit. Geometrically, the limit of the secant lines is the tangent line. Therefore, the limit of the difference quotient as approaches zero, if it exists, should represent the slope of the tangent line to . This limit is defined to be the derivative of the function at : When the limit exists, is said to be differentiable at . Here is one of several common notations for the derivative (see below). From this definition it is obvious that a differentiable function is increasing if and only if its derivative is positive, and is decreasing iff its derivative is negative. This fact is used extensively when analyzing function behavior, e.g. when finding local extrema. Equivalently, the derivative satisfies the property that which has the intuitive interpretation (see Figure 1) that the tangent line to at gives the best linear approximation to near (i.e., for small ). This interpretation is the easiest to generalize to other settings (see below). Substituting 0 for in the difference quotient causes division by zero, so the slope of the tangent line cannot be found directly using this method. Instead, define to be the difference quotient as a function of : is the slope of the secant line between and . If is a continuous function, meaning that its graph is an unbroken curve with no gaps, then is a continuous function away from . If the limit exists, meaning that there is a way of choosing a value for that makes a continuous function, then the function is differentiable at , and its derivative at equals . In practice, the existence of a continuous extension of the difference quotient to is shown by modifying the numerator to cancel in the denominator. Such manipulations can make the limit value of for small clear even though is still not defined at . This process can be long and tedious for complicated functions, and many shortcuts are commonly used to simplify the process. Example The square function given by is differentiable at , and its derivative there is 6. This result is established by calculating the limit as approaches zero of the difference quotient of : The last expression shows that the difference quotient equals when and is undefined when , because of the definition of the difference quotient. However, the definition of the limit says the difference quotient does not need to be defined when . The limit is the result of letting go to zero, meaning it is the value that tends to as becomes very small: Hence the slope of the graph of the square function at the point is , and so its derivative at is . More generally, a similar computation shows that the derivative of the square function at is : Continuity and differentiability If is differentiable at , then must also be continuous at . As an example, choose a point and let be the step function that returns the value 1 for all less than , and returns a different value 10 for all greater than or equal to . cannot have a derivative at . If is negative, then is on the low part of the step, so the secant line from to is very steep, and as tends to zero the slope tends to infinity. If is positive, then is on the high part of the step, so the secant line from to has slope zero. Consequently, the secant lines do not approach any single slope, so the limit of the difference quotient does not exist. However, even if a function is continuous at a point, it may not be differentiable there. For example, the absolute value function given by is continuous at , but it is not differentiable there. If is positive, then the slope of the secant line from 0 to is one, whereas if is negative, then the slope of the secant line from 0 to is negative one. This can be seen graphically as a "kink" or a "cusp" in the graph at . Even a function with a smooth graph is not differentiable at a point where its tangent is vertical: For instance, the function given by is not differentiable at . In summary, a function that has a derivative is continuous, but there are continuous functions that do not have a derivative. Most functions that occur in practice have derivatives at all points or at almost every point. Early in the history of calculus, many mathematicians assumed that a continuous function was differentiable at most points. Under mild conditions, for example if the function is a monotone function or a Lipschitz function, this is true. However, in 1872 Weierstrass found the first example of a function that is continuous everywhere but differentiable nowhere. This example is now known as the Weierstrass function. In 1931, Stefan Banach proved that the set of functions that have a derivative at some point is a meager set in the space of all continuous functions. Informally, this means that hardly any random continuous functions have a derivative at even one point. Derivative as a function Let be a function that has a derivative at every point in its domain. We can then define a function that maps every point to the value of the derivative of at . This function is written and is called the derivative function or the derivative of . Sometimes has a derivative at most, but not all, points of its domain. The function whose value at equals whenever is defined and elsewhere is undefined is also called the derivative of . It is still a function, but its domain is strictly smaller than the domain of . Using this idea, differentiation becomes a function of functions: The derivative is an operator whose domain is the set of all functions that have derivatives at every point of their domain and whose range is a set of functions. If we denote this operator by , then is the function . Since is a function, it can be evaluated at a point . By the definition of the derivative function, . For comparison, consider the doubling function given by ; is a real-valued function of a real number, meaning that it takes numbers as inputs and has numbers as outputs: The operator , however, is not defined on individual numbers. It is only defined on functions: Because the output of is a function, the output of can be evaluated at a point. For instance, when is applied to the square function, , outputs the doubling function , which we named . This output function can then be evaluated to get , , and so on. Higher derivatives Let be a differentiable function, and let be its derivative. The derivative of (if it has one) is written and is called the second derivative of . Similarly, the derivative of the second derivative, if it exists, is written and is called the third derivative of . Continuing this process, one can define, if it exists, the th derivative as the derivative of the th derivative. These repeated derivatives are called higher-order derivatives. The th derivative is also called the derivative of order and denoted . If represents the position of an object at time , then the higher-order derivatives of have specific interpretations in physics. The first derivative of is the object's velocity. The second derivative of is the acceleration. The third derivative of is the jerk. And finally, the fourth through sixth derivatives of are snap, crackle, and pop; most applicable to astrophysics. A function need not have a derivative (for example, if it is not continuous). Similarly, even if does have a derivative, it may not have a second derivative. For example, let Calculation shows that is a differentiable function whose derivative at is given by {{math|f(x)}} is twice the absolute value function at , and it does not have a derivative at zero. Similar examples show that a function can have a th derivative for each non-negative integer but not a th derivative. A function that has successive derivatives is called times differentiable. If in addition the th derivative is continuous, then the function is said to be of differentiability class . (This is a stronger condition than having derivatives, as shown by the second example of .) A function that has infinitely many derivatives is called infinitely differentiable or smooth. On the real line, every polynomial function is infinitely differentiable. By standard differentiation rules, if a polynomial of degree is differentiated times, then it becomes a constant function. All of its subsequent derivatives are identically zero. In particular, they exist, so polynomials are smooth functions. The derivatives of a function at a point provide polynomial approximations to that function near . For example, if is twice differentiable, then in the sense that If is infinitely differentiable, then this is the beginning of the Taylor series for evaluated at around . Inflection point A point where the second derivative of a function changes sign is called an inflection point. At an inflection point, the second derivative may be zero, as in the case of the inflection point of the function given by , or it may fail to exist, as in the case of the inflection point of the function given by . At an inflection point, a function switches from being a convex function to being a concave function or vice versa. Notation (details) Leibniz's notation The symbols , , and were introduced by Gottfried Wilhelm Leibniz in 1675. It is still commonly used when the equation is viewed as a functional relationship between dependent and independent variables. Then the first derivative is denoted by and was once thought of as an infinitesimal quotient. Higher derivatives are expressed using the notation for the nth derivative of . These are abbreviations for multiple applications of the derivative operator. For example, With Leibniz's notation, we can write the derivative of at the point in two different ways: Leibniz's notation allows one to specify the variable for differentiation (in the denominator), which is relevant in partial differentiation. It also can be used to write the chain rule as Lagrange's notation Sometimes referred to as prime notation, one of the most common modern notations for differentiation is due to Joseph-Louis Lagrange and uses the prime mark, so that the derivative of a function is denoted . Similarly, the second and third derivatives are denoted and To denote the number of derivatives beyond this point, some authors use Roman numerals in superscript, whereas others place the number in parentheses: or The latter notation generalizes to yield the notation for the nth derivative of – this notation is most useful when we wish to talk about the derivative as being a function itself, as in this case the Leibniz notation can become cumbersome. Newton's notation Newton's notation for differentiation, also called the dot notation, places a dot over the function name to represent a time derivative. If , then and denote, respectively, the first and second derivatives of . This notation is used exclusively for derivatives with respect to time or arc length. It is typically used in differential equations in physics and differential geometry. The dot notation, however, becomes unmanageable for high-order derivatives (order 4 or more) and cannot deal with multiple independent variables. Euler's notation Euler's notation uses a differential operator , which is applied to a function to give the first derivative . The nth derivative is denoted . If is a dependent variable, then often the subscript x is attached to the D to clarify the independent variable x. Euler's notation is then written or , although this subscript is often omitted when the variable x is understood, for instance when this is the only independent variable present in the expression. Euler's notation is useful for stating and solving linear differential equations. Rules of computation The derivative of a function can, in principle, be computed from the definition by considering the difference quotient, and computing its limit. In practice, once the derivatives of a few simple functions are known, the derivatives of other functions are more easily computed using rules for obtaining derivatives of more complicated functions from simpler ones. Rules for basic functions Here are the rules for the derivatives of the most common basic functions, where a is a real number. Derivatives of powers: Exponential and logarithmic functions: Trigonometric functions: Inverse trigonometric functions: Rules for combined functions Here are some of the most basic rules for deducing the derivative of a compound function from derivatives of basic functions. Constant rule: if f(x) is constant, then Sum rule: for all functions f and g and all real numbers and . Product rule: for all functions f and g. As a special case, this rule includes the fact whenever is a constant, because by |
Henry Heras, Kamil Zvelebil, Asko Parpola and Iravatham Mahadevan as being strong evidence for a proto-Dravidian origin of the ancient Indus Valley civilisation. The discovery in Tamil Nadu of a late Neolithic (early 2nd millennium BCE, i.e. post-dating Harappan decline) stone celt allegedly marked with Indus signs has been considered by some to be significant for the Dravidian identification. Yuri Knorozov surmised that the symbols represent a logosyllabic script and suggested, based on computer analysis, an underlying agglutinative Dravidian language as the most likely candidate for the underlying language. Knorozov's suggestion was preceded by the work of Henry Heras, who suggested several readings of signs based on a proto-Dravidian assumption. Linguist Asko Parpola writes that the Indus script and Harappan language are "most likely to have belonged to the Dravidian family". Parpola led a Finnish team in investigating the inscriptions using computer analysis. Based on a proto-Dravidian assumption, they proposed readings of many signs, some agreeing with the suggested readings of Heras and Knorozov (such as equating the "fish" sign with the Dravidian word for fish, "min") but disagreeing on several other readings. A comprehensive description of Parpola's work until 1994 is given in his book Deciphering the Indus Script. Northern Dravidian pockets Although in modern times speakers of the various Dravidian languages have mainly occupied the southern portion of India, in earlier times they probably were spoken in a larger area. After the Indo-Aryan migrations into north-western India, starting ca. 1500 BCE, and the establishment of the Kuru kingdom ca. 1100 BCE, a process of Sanskritisation of the masses started, which resulted in a language shift in northern India. Southern India has remained majority Dravidian, but pockets of Dravidian can be found in central India, Pakistan and Nepal. The Kurukh and Malto are pockets of Dravidian languages in central India, spoken by people who may have migrated from south India. They do have myths about external origins. The Kurukh have traditionally claimed to be from the Deccan Peninsula, more specifically Karnataka. The same tradition has existed of the Brahui, who call themselves immigrants. Holding this same view of the Brahui are many scholars such as L.H. Horace Perera and M.Ratnasabapathy. The Brahui population of Pakistan's Balochistan province has been taken by some as the linguistic equivalent of a relict population, perhaps indicating that Dravidian languages were formerly much more widespread and were supplanted by the incoming Indo-Aryan languages. However, it has been argued that the absence of any Old Iranian (Avestan) loanwords in Brahui suggests that the Brahui migrated to Balochistan from central India less than 1,000 years ago. The main Iranian contributor to Brahui vocabulary, Balochi, is a western Iranian language like Kurdish, and arrived in the area from the west only around 1000 CE. Sound changes shared with Kurukh and Malto also suggest that Brahui was originally spoken near them in central India. Dravidian influence on Sanskrit Dravidian languages show extensive lexical (vocabulary) borrowing, but only a few traits of structural (either phonological or grammatical) borrowing from Indo-Aryan, whereas Indo-Aryan shows more structural than lexical borrowings from the Dravidian languages. Many of these features are already present in the oldest known Indo-Aryan language, the language of the Rigveda (c.1500 BCE), which also includes over a dozen words borrowed from Dravidian. Vedic Sanskrit has retroflex consonants (/, ) with about 88 words in the Rigveda having unconditioned retroflexes. Some sample words are , , , , and . Since other Indo-European languages, including other Indo-Iranian languages, lack retroflex consonants, their presence in Indo-Aryan is often cited as evidence of substrate influence from close contact of the Vedic speakers with speakers of a foreign language family rich in retroflex consonants. The Dravidian family is a serious candidate since it is rich in retroflex phonemes reconstructible back to the Proto-Dravidian stage. In addition, a number of grammatical features of Vedic Sanskrit not found in its sister Avestan language appear to have been borrowed from Dravidian languages. These include the gerund, which has the same function as in Dravidian. Some linguists explain this asymmetrical borrowing by arguing that Middle Indo-Aryan languages were built on a Dravidian substratum. These scholars argue that the most plausible explanation for the presence of Dravidian structural features in Indic is language shift, that is, native Dravidian speakers learning and adopting Indic languages due to elite dominance. Although each of the innovative traits in Indic could be accounted for by internal explanations, early Dravidian influence is the only explanation that can account for all of the innovations at once; moreover, it accounts for several of the innovative traits in Indic better than any internal explanation that has been proposed. Grammar The most characteristic grammatical features of Dravidian languages are: Dravidian languages are agglutinative. Word order is subject–object–verb (SOV). Most Dravidian languages have a clusivity distinction. The major word classes are nouns (substantives, numerals, pronouns), adjectives, verbs, and indeclinables (particles, enclitics, adverbs, interjections, onomatopoetic words, echo words). Proto-Dravidian used only suffixes, never prefixes or infixes, in the construction of inflected forms. Hence, the roots of words always occurred at the beginning. Nouns, verbs, and indeclinable words constituted the original word classes. There are two numbers and four different gender systems, the ancestral system probably having "male:non-male" in the singular and "person:non-person" in the plural. In a sentence, however complex, only one finite verb occurs, normally at the end, preceded if necessary by a number of gerunds. Word order follows certain basic rules but is relatively free. The main (and probably original) dichotomy in tense is past:non-past. Present tense developed later and independently in each language or subgroup. Verbs are intransitive, transitive, and causative; there are also active and passive forms. All of the positive verb forms have their corresponding negative counterparts, negative verbs. Phonology Dravidian languages are noted for the lack of distinction between aspirated and unaspirated stops. While some Dravidian languages have accepted large numbers of loanwords from Sanskrit and other Indo-Iranian languages in addition to their already vast vocabulary, in which the orthography shows distinctions in voice and aspiration, the words are pronounced in Dravidian according to different rules of phonology and phonotactics: aspiration of plosives is generally absent, regardless of the spelling of the word. This is not a universal phenomenon and is generally avoided in formal or careful speech, especially when reciting. For instance, Tamil does not distinguish between voiced and voiceless stops. In fact, the Tamil alphabet lacks symbols for voiced and aspirated stops. Dravidian languages are also characterized by a three-way distinction between dental, alveolar, and retroflex places of articulation as well as large numbers of liquids. Proto-Dravidian Proto-Dravidian had five short and long vowels: *a, *ā, *i, *ī, *u, *ū, *e, *ē, *o, *ō. There were no diphthongs; ai and au are treated as *ay and *av (or *aw). The five-vowel system is largely preserved in the descendent subgroups. The following consonantal phonemes are reconstructed: Numerals The numerals from 1 to 10 in various Dravidian and Indo-Aryan languages (here exemplified by Indo Aryan language Sanskrit and Iranian language Persian). This is the same as the word for another form of the number one in Tamil and Malayalam, used as the indefinite article ("a") and when the number is an attribute preceding a noun (as in "one person"), as opposed to when it is a noun (as in "How many are there?" "One"). The stem *īr is still found in compound words, and has taken on a meaning of "double" in Tamil, Telugu, Kannada and Malayalam. For example, irupatu (20, literally meaning "double-ten"), iravai (20 in Telugu), "iraṭṭi" ("double") or iruvar ("two people", in Tamil) and "ippatthu" (ipp-hatthu, double ten", in Kannada). The Kolami numbers 5 to 10 are borrowed from Telugu. The word tondu was also used to refer to the number nine in ancient Sangam texts but was later completely replaced by the word onpadu. These forms are derived from "one (less than) ten". Proto-Dravidian *toḷ is still used in Tamil and Malayalam as the basis of numbers such as 90, thonnooru as well as the Kannada tombattu. Words indicated (II) are borrowings from Indo-Iranian languages (in Brahui's case, from Balochi). Literature Four Dravidian languages, viz. Tamil, Kannada, Telugu and Malayalam, have lengthy literary traditions. Literature in Tulu and Kodava is more recent. Recently old literature in Gondi has been discovered as well. The earliest known Dravidian inscriptions are 76 Old Tamil inscriptions on cave walls in Madurai and Tirunelveli districts in Tamil Nadu, dating from the 2nd century BCE. These inscriptions are written in a variant of the Brahmi script called Tamil Brahmi. In 2019, the Tamil Nadu Archaeology Department released a report on excavations at Keeladi, near Madurai, Tamil Nadu, including a description of potsherds dated to the 6th century BCE inscribed with personal names in the Tamil-Brahmi script. However, the report lacks the detail of a full archaeological study, and other archaeologists have disputed whether the oldest dates obtained for the site can be assigned to these potsherds. The earliest long text in Old Tamil is the Tolkāppiyam, a work on Tamil grammar and poetics preserved in a 5th-century CE redaction, whose oldest layers could date from the late 2nd century or 1st century BCE. Kannada is first known from the Halmidi inscription (450 CE). A 9th-century treatise on poetics, the Kavirajamarga, is the first literary work. The earliest Telugu inscription, from Erragudipadu in Kadapa district, | almost 150 million speakers. Tamil, Kannada and Malayalam make up around 98% of the speakers, with 75 million, 44 million and 37 million native speakers, respectively. The next-largest is the South-Central branch, which has 78 million native speakers, the vast majority of whom speak Telugu. The total number of speakers of Telugu, including those whose first language is not Telugu, is around 84 million people. This branch also includes the tribal language Gondi spoken in central India. The second-smallest branch is the Northern branch, with around 6.3 million speakers. This is the only sub-group to have a language spoken in Pakistan — Brahui. The smallest branch is the Central branch, which has only around 200,000 speakers. These languages are mostly tribal, and spoken in central India. Languages recognized as official languages of India appear here in boldface. Proposed relations with other families The Dravidian family has defied all of the attempts to show a connection with other languages, including Indo-European, Hurrian, Basque, Sumerian, Korean and Japanese. Comparisons have been made not just with the other language families of the Indian subcontinent (Indo-European, Austroasiatic, Sino-Tibetan, and Nihali), but with all typologically similar language families of the Old World. Nonetheless, although there are no readily detectable genealogical connections, Dravidian shares strong areal features with the Indo-Aryan languages, which have been attributed to a substratum influence from Dravidian. Dravidian languages display typological similarities with the Uralic language group, and there have been several attempts to establish a genetic relationship in the past. This idea has been popular amongst Dravidian linguists, including Robert Caldwell, Thomas Burrow, Kamil Zvelebil, and Mikhail Andronov, The hypothesis is, however, rejected by most specialists in Uralic languages, and also in recent times by Dravidian linguists such as Bhadriraju Krishnamurti. In the early 1970s, the linguist David McAlpin produced a detailed proposal of a genetic relationship between Dravidian and the extinct Elamite language of ancient Elam (present-day southwestern Iran). The Elamo-Dravidian hypothesis was supported in the late 1980s by the archaeologist Colin Renfrew and the geneticist Luigi Luca Cavalli-Sforza, who suggested that Proto-Dravidian was brought to India by farmers from the Iranian part of the Fertile Crescent. (In his 2000 book, Cavalli-Sforza suggested western India, northern India and northern Iran as alternative starting points.) However, linguists have found McAlpin's cognates unconvincing and criticized his proposed phonological rules as ad hoc. Elamite is generally believed by scholars to be a language isolate, and the theory has had no effect on studies of the language. In 2012, Southworth suggested a "Zagrosian family" of West Asian origin including Elamite, Brahui and Dravidian as its three branches. Dravidian is one of the primary language families in the Nostratic proposal, which would link most languages in North Africa, Europe and Western Asia into a family with its origins in the Fertile Crescent sometime between the Last Glacial Period and the emergence of Proto-Indo-European 4,000–6,000 BCE. However, the general consensus is that such deep connections are not, or not yet, demonstrable. Prehistory The origins of the Dravidian languages, as well as their subsequent development and the period of their differentiation are unclear, partially due to the lack of comparative linguistic research into the Dravidian languages. Though some scholars have argued that the Dravidian languages may have been brought to India by migrations in the fourth or third millennium BCE or even earlier, the Dravidian languages cannot easily be connected to any other language, and they could well be indigenous to India. Proto-Dravidian was spoken in the 4th or 3rd millennium BCE, and it is thought that the Dravidian languages were the most widespread indigenous languages in the Indian subcontinent before the advance of the Indo-Aryan languages. Proto-Dravidian and onset of diversification As a proto-language, the Proto-Dravidian language is not itself attested in the historical record. Its modern conception is based solely on reconstruction. It was suggested in the 1980s that the language was spoken in the 4th millennium BCE, and started disintegrating into various branches around the 3rd millennium BCE. According to Krishnamurti, Proto-Dravidian may have been spoken in the Indus civilization, suggesting a "tentative date of Proto-Dravidian around the early part of the third millennium." Krishnamurti further states that South Dravidian I (including pre-Tamil) and South Dravidian II (including Pre-Telugu) split around the eleventh century BCE, with the other major branches splitting off at around the same time. Kolipakam et al. (2018) estimate the Dravidian language family to be approximately 4,500 years old. Several geneticists have noted a strong correlation between Dravidian and the Ancestral South Indian (ASI) component of South Asian genetic makeup. Narasimhan et al. (2018) argue that the ASI component itself resulted from a mixture of Iranian-related agriculturalists, moving southeast after the decline of the Indus Valley Civilization (early 2nd millennium BCE), and hunter-gatherers native to southern India. They conclude that one of these two groups may have been the source of proto-Dravidian. Introduction from the northwest would be consistent with the location of Brahui and with attempts to interpret the Indus script as Dravidian. On the other hand, reconstructed Proto-Dravidian terms for flora and fauna provide some support for an Indian origin. Indus Valley Civilisation The Indus Valley civilisation (3,300–1,900 BCE), located in Northwestern Indian subcontinent, is sometimes suggested to have been Dravidian. Already in 1924, when announcing the discovery of the IVC, John Marshall stated that (one of) the language(s) may have been Dravidic. Cultural and linguistic similarities have been cited by researchers Henry Heras, Kamil Zvelebil, Asko Parpola and Iravatham Mahadevan as being strong evidence for a proto-Dravidian origin of the ancient Indus Valley civilisation. The discovery in Tamil Nadu of a late Neolithic (early 2nd millennium BCE, i.e. post-dating Harappan decline) stone celt allegedly marked with Indus signs has been considered by some to be significant for the Dravidian identification. Yuri Knorozov surmised that the symbols represent a logosyllabic script and suggested, based on computer analysis, an underlying agglutinative Dravidian language as the most likely candidate for the underlying language.

the novel are true, and that "for obvious reasons" he had changed the names of places and people. Although scholars had been aware of the translation's existence since the 1980s because of Stoker's preface, none had thought to translate it back into English. Makt Myrkranna differs significantly from Stoker's novel. Character names were changed, the length was abridged, and it was more overtly sexual than the original. Dutch scholar Hans Corneel de Roos compared the translation favourably to Stoker's, writing that where Dracula meandered, the translation was concise and punchy. Major themes Gender and sexuality Academic analyses of Dracula as sexually charged have become so frequent that a cottage industry has developed around the topic. Sexuality and seduction are two of the novel's most frequently discussed themes, especially as it relates to the corruption of English womanhood. Modern critical writings about vampirism widely acknowledge its link to sex and sexuality. Bram Stoker himself was possibly homosexual; Talia Schaffer points to intensely homoerotic letters sent by him to the American poet Walt Whitman. Stoker began writing the novel one month following the imprisonment of his friend Oscar Wilde for homosexuality. The novel's characters are often said to represent transgressive sexuality through the performance of their genders. The primary sexual threat posed by Count Dracula is, Christopher Craft writes, that he will "seduce, penetrate, [and] drain another male", with Jonathan Harker's excitement about being penetrated by three vampire women serving as a mask and proxy for his homosexual desire. His excitement also inverts standard Victorian gender roles; in succumbing to the vampire women, Harker assumes the traditionally feminine role of sexual passivity while the vampire women assume the masculinised role of acting. Sexual depravity and aggression were understood by the Victorians as the exclusive domain of Victorian men, while women were expected to submit to their husband's sexual wishes. Harker's desire to submit, and the scene's origin as a dream Stoker had, highlights the divide between societal expectations and lived realities of men who wanted more freedom in their sexual lives. In the British version of the text, Harker hears the three vampire women whispering at his door, and Dracula tells them they can feed on him tomorrow night. In the American version, Dracula insinuates that he will be feeding on Harker that night: "To-night is mine! To-morrow is yours!" Nina Auerbach and David J. Skal, in the Norton Critical Edition of the text, posit that Stoker thought the line would render the novel unpublishable in 1897 England, and that "the America that produced his hero Walt Whitman would have been more tolerant of men feeding on men". The novel's depiction of women continues to divide critics. Elaine Showalter writes that Lucy Westenra and Mina Harker represent different aspects of the New Woman. According to Showalter, Lucy represents the "sexual daring" of the New Woman, evidenced by how she wonders why a woman cannot marry three men if they all desire her. Mina, meanwhile, represents the New Woman's "intellectual ambitions", citing her occupation as a schoolmaster, her keen mind, and her knowledge of shorthand. Carol A. Senf writes that Stoker was ambivalent about the New Woman phenomenon. Of the novel's five vampires, four are women, and all are aggressive, "wildly erotic", and driven only by their thirst for blood. Mina Harker, meanwhile, serves as the antithesis of the other female characters, and plays a singularly important role in Dracula's defeat. On the other hand, Judith Wasserman argues that the fight to defeat Dracula is really a battle for control over women's bodies. Senf points out that Lucy's sexual awakening, and her reversal of gender-based sexual roles, is what Abraham Van Helsing considers a threat. Race Dracula, and specifically the Count's migration to Victorian England, is frequently read as emblematic of invasion literature, and a projection of fears about racial pollution. A number of scholars have indicated that Dracula version of the vampire myth participates in antisemitic stereotyping. Jules Zanger links the novel's portrayal of the vampire to the appearance of Eastern European Jews in fin de siècle England. Between 1881 and 1900, the number of Jews living in England had increased sixfold because of pogroms and antisemitic laws. Jack Halberstam provides a list of Dracula's associations with antisemitic conceptions of Jewish people: his appearance, wealth, parasitic bloodlust, and "lack of allegiance" to one country. In terms of his appearance, Halbertstam notes Dracula's resemblance to other fictional Jews; for example, his long, sharp nails are compared to those of Fagin in Charles Dickens's Oliver Twist (1838), and Svengali of George du Maurier's Trilby (1895), who is depicted as animalistic and thin. The novel's depiction of Slovaks and Romani people has attracted some, albeit limited, scholarly attention. Peter Arnds wrote that the Count's control over the Romani and his abduction of young children evokes real folk superstitions about Romani people stealing children, and that his ability to transform into a wolf is likewise related to xenophobic beliefs about the Romani as animalistic. Although vagrants of all kinds were associated with animals, the Romani were especially persecuted because of an English belief that they enjoyed "unclean meat" and lived among animals. Stoker's description of the Slovaks draws heavily from a travel memoir by a British major. Unlike the major's description, Harker's description is overtly imperialistic, labelling the people as "barbarians" and their boats as "primitive", emphasising their perceived cultural inferiority. Stephen Arata describes the novel as a case of "reverse colonisation"; that is, a fear of the non-white invading England and weakening its racial purity. Arata describes the novel's cultural context of mounting anxiety in Britain over the decline of the British Empire, the rise of other world powers, and a "growing domestic unease" over the morality of imperial colonisation. Manifesting also in other works aside from Stoker's novel, narratives of reverse colonisation indicate a fear of the "civilised" world being invaded by the "primitive". What Dracula does to human bodies is not horrifying simply because he kills them, but because he transforms them into the racial Other. Monika Tomaszewska associates Dracula's status as the racial Other with his characterisation as a degenerate criminal. She explains that, at the time of the novel's composition and publication, the "threatening degenerate was commonly identified as the racial Other, the alien intruder who invades the country to disrupt the domestic order and enfeeble the host race". Disease The novel's representation of vampirism has been discussed as symbolising Victorian anxieties about disease. The theme is discussed with far less frequency than others because it is discussed alongside other topics rather than as the central object of discussion. For example, some connect its depiction of disease with race. Jack Halberstam points to one scene in which an English worker says that the repugnant odour of Count Dracula's London home smells like Jerusalem, making it a "Jewish smell". Jewish people were frequently described, in Victorian literature, as parasites; Halberstam highlights one particular fear that Jews would spread diseases of the blood, and one journalist's description of Jews as "Yiddish bloodsuckers". In contrast, Mathias Clasen writes parallels between vampirism and sexually-transmitted diseases, specifically syphilis. Martin Willis, a researcher focused on the intersection of literature and disease, argues that the novel's characterisation of vampirism makes it both the initial infection and resulting illness. Style Narrative As an epistolary novel, Dracula is narrated through a series of documents. The novel's first four chapters are related as the journals of Jonathan Harker. Scholar David Seed notes that Harker's accounts function as an attempt to translocate the "strange" events of his visit to Dracula's castle into the nineteenth-century tradition of travelogue writing. John Seward, Mina Murray and Jonathan Harker all keep a crystalline account of the period as an act of self-preservation; David Seed notes that Harker's narrative is written in shorthand to remain inscrutable to the Count, protecting his own identity, which Dracula threatens to destroy. Harker's journal, for example, embodies the only advantage during his stay at Dracula's castle: that he knows more than the Count thinks he does. The novel's disparate accounts approach a kind of narrative unity as the narrative unfolds. In the novel's first half, each narrator has a strongly characterised narrative voice, with Lucy's showing her verbosity, Seward's businesslike formality, and Harker's excessive politeness. These narrative styles also highlight the power struggle between vampire and his hunters; the increasing prominence of Van Helsing's broken English as Dracula gathers power represents the entrance of the foreigner into Victorian society. Genre Dracula is a common reference text in discussions of Gothic fiction. Jerrold E. Hogle notes Gothic fiction's tendency to blur boundaries, pointing to sexual orientation, race, class, and even species. Relating this to Dracula, he highlights that the Count "can disgorge blood from his breasts" in addition to his teeth; that he is attracted to both Jonathan Harker and Mina Murray; appears both racially western and eastern; and how he is an aristocrat able to mingle with homeless vagrants. Stoker drew extensively from folklore in crafting Count Dracula, but many of the Count's physical attributes were typical of Gothic villains during Stoker's lifetime. In particular, his hooked nose, pale complexion, large moustache and thick eyebrows were likely inspired by the villains of Gothic fiction. Likewise, Stoker's selection of Transylvania has roots in the Gothic. Writers of the mode were drawn to Eastern Europe as a setting because travelogues presented it as a land of primitive superstitions. Dracula deviates from Gothic tales before it by firmly establishing its time—that being the modern era. The novel is an example of Urban Gothic. Dracula became the subject of critical interest into Irish fiction during the early 1990s. Dracula is set largely in England, but Stoker was born in Ireland, which was at that time a British colony, and lived there for the first 30 years of his life. As a result, a significant body of writing exists on Dracula, Ireland, England, and colonialism. Calvin W. Keogh writes that Harker's voyage into Eastern Europe "bears comparison with the Celtic fringe to the west", highlighting them both as "othered" spaces. Keogh notes that the Eastern Question has been both symbolically and historically associated with the Irish question. In this reading, Transylvania functions as a stand-in for Ireland. Several critics have described Count Dracula as an Anglo-Irish landlord. Reception Upon publication, Dracula was well received. Reviewers frequently compared the novel to other Gothic writers, and mentions of novelist Wilkie Collins and The Woman in White (1859) were especially common because of similarities in structure and style. A review appearing in The Bookseller notes that the novel could almost have been written by Collins, and an anonymous review in Saturday Review of Politics, Literature, Science and Art wrote that Dracula improved upon the style of Gothic pioneer Ann Radcliffe. Another anonymous writer described Stoker as "the Edgar Allan Poe of the nineties". Other favourable comparisons to other Gothic novelists include the Brontë sisters and Mary Shelley. Many of these early reviews were charmed by Stoker's unique treatment of the vampire myth. One called it the best vampire story ever written. The Daily Telegraph reviewer noted that while earlier Gothic works, like The Castle of Otranto, had kept the supernatural far away from the novelists' home countries, Dracula horrors | a newly qualified English solicitor, visits Count Dracula at his castle in the Carpathian Mountains to help the Count purchase a house near London. Ignoring the Count's warning, Harker wanders the castle and encounters three vampire women; Dracula rescues Harker, and gives the women a small child bound inside a bag. Harker awakens in bed; soon after, Dracula leaves the castle, abandoning him to the women; Harker escapes with his life and ends up delirious in a Budapest hospital. Dracula takes a ship for England with boxes of earth from his castle. The captain's log narrates the crew's disappearance until he alone remains, bound to the helm to maintain course. An animal resembling a large dog is seen leaping ashore when the ship runs aground at Whitby. Lucy Westenra's letter to her best friend, Harker's fiancée Mina Murray, describes her marriage proposals from Dr. John Seward, Quincey Morris, and Arthur Holmwood. Lucy accepts Holmwood's, but all remain friends. Mina joins her friend Lucy on holiday in Whitby. Lucy begins sleepwalking. After his ship lands there, Dracula stalks Lucy. Mina receives a letter about her missing fiancé's illness, and goes to Budapest to nurse him. Lucy becomes very ill. Seward's old teacher, Professor Abraham Van Helsing, determines the nature of Lucy's condition, but refuses to disclose it. He diagnoses her with acute blood-loss. Van Helsing places garlic flowers around her room and makes her a necklace of them. Lucy's mother removes the garlic flowers, not knowing they repel vampires. While Seward and Van Helsing are absent, Lucy and her mother are terrified by a wolf and Mrs. Westenra dies of a heart attack; Lucy dies shortly thereafter. After her burial, newspapers report children being stalked in the night by a "bloofer lady" (beautiful lady), and Van Helsing deduces it is Lucy. The four go to her tomb and see that she is a vampire. They stake her heart, behead her, and fill her mouth with garlic. Jonathan Harker and his now-wife Mina have returned, and they join the campaign against Dracula. Everyone stays at Dr. Seward's asylum as the men begin to hunt Dracula. Van Helsing finally reveals that vampires can only rest on earth from their homeland. Dracula communicates with Seward's patient, Renfield, an insane man who eats vermin to absorb their life force. After Dracula learns of the group's plot against him, he uses Renfield to enter the asylum. He secretly attacks Mina three times, drinking her blood each time and forcing Mina to drink his blood on the final visit. She is cursed to become a vampire after her death unless Dracula is killed. As the men find Dracula's properties, they discover many earth boxes within. The vampire hunters open each of the boxes and seal wafers of sacramental bread inside them, rendering them useless to Dracula. They attempt to trap the Count in his Piccadilly house, but he escapes. They learn that Dracula is fleeing to his castle in Transylvania with his last box. Mina has a faint psychic connection to Dracula, which Van Helsing exploits via hypnosis to track Dracula's movements. Guided by Mina, they pursue him. In Galatz, Romania, the hunters split up. Van Helsing and Mina go to Dracula's castle, where the professor destroys the vampire women. Jonathan Harker and Arthur Holmwood follow Dracula's boat on the river, while Quincey Morris and John Seward parallel them on land. After Dracula's box is finally loaded onto a wagon by Szgany men, the hunters converge and attack it. After routing the Szgany, Harker slashes Dracula's neck and Quincey stabs him in the heart. Dracula crumbles to dust, freeing Mina from her vampiric curse. Quincey is mortally wounded in the fight against the Szgany. He dies from his wounds, at peace with the knowledge that Mina is saved. A note by Jonathan Harker seven years later states that the Harkers have a son, named Quincey. Background Author As the acting manager of the Lyceum Theatre in London, Bram Stoker was a recognisable figure: he would greet evening guests, and served as assistant to the stage actor Henry Irving. In a letter to Walt Whitman, Stoker described his own temperament as "secretive to the world", but he nonetheless led a relatively public life. Stoker supplemented his income from the theatre by writing romance and sensation novels, and had published 18 books by his death in 1912. Dracula was Stoker's seventh published book, following The Shoulder of Shasta (1895) and preceding Miss Betty (1898). Hall Caine, a close friend of Stoker's, wrote an obituary for him in The Daily Telegraph, saying that—besides his biography on Irving—Stoker wrote only "to sell" and "had no higher aims". Influences Many figures have been suggested as inspirations for Count Dracula, but there is no consensus. In his 1962 biography of Stoker, Harry Ludlam suggested that Ármin Vámbéry, a professor at the University of Budapest, supplied Stoker with information about Vlad Drăculea, commonly known as Vlad the Impaler. Professors Raymond T. McNally and Radu Florescu popularised the idea in their 1972 book, In Search of Dracula. Benjamin H. LeBlanc writes that there is a reference within the text to Vámbéry, an "Arminius, of Buda-Pesh University", who is familiar with the historical Vlad III and is a friend of Abraham Van Helsing, but an investigation by McNally and Florescu found nothing about "Vlad, Dracula, or vampires" within Vámbéry's published papers, nor in Stoker's notes about his meeting with Vámbéry. Academic and Dracula scholar Elizabeth Miller calls the link to Vlad III "tenuous", indicating that Stoker incorporated a large amount of "insignificant detail" from his research, and rhetorically asking why he would omit Vlad III's infamous cruelty. Raymond McNally's Dracula Was A Woman (1983) suggests another historical figure as an inspiration: Elizabeth Báthory. McNally argues that the imagery of Dracula has analogues in Báthory's described crimes, such as the use of a cage resembling an iron maiden. Gothic critic and lecturer Marie Mulvey-Roberts writes that vampires were traditionally depicted as "mouldering revenants, who dragged themselves around graveyards", but—like Báthory—Dracula uses blood to restore his youth. Recent scholarship has questioned whether Báthory's crimes were exaggerated by her political opponents, with others noting that very little is concretely known about her life. A book that Stoker used for research, The Book of Were-Wolves, does have some information on Báthory, but Miller writes that he never took notes on anything from the short section devoted to her. In a facsimile edition of Bram Stoker's original notes for the book, Miller and her co-author Robert Eighteen-Bisang say in a footnote that there is no evidence she inspired Stoker. In 2000, Miller's book-length study, Dracula: Sense and Nonsense, was said by academic Noel Chevalier to correct "not only leading Dracula scholars, but non-specialists and popular film and television documentaries". Aside from the historical, Count Dracula also has literary progenitors. Academic Elizabeth Signorotti argues that Dracula is a response to the lesbian vampire of Sheridan Le Fanu's Carmilla (1872), "correcting" its emphasis on female desire. Bram Stoker's great-nephew, broadcaster Daniel Farson, wrote a biography of the author; in it, he doubts that Stoker was aware of the lesbian elements of Carmilla, but nonetheless notes that it influenced him profoundly. Farson writes that an inscription upon a tomb in Dracula is a direct allusion to Carmilla. Scholar Alison Milbank observes that as Dracula can transform into a dog, Carmilla can become a cat. According to author Patrick McGrath, "traces of Carmilla" can be found in the three female vampires residing in Dracula castle. A short story written by Stoker and published after his death, "Dracula's Guest", has been seen as evidence of Carmilla influence. According to Milbank, the story was a deleted first chapter from early in the original manuscript, and replicates Carmilla setting of Styria instead of Transylvania. Textual history Composition Prior to writing the novel, Stoker researched extensively, assembling over 100 pages of notes, including chapter summaries and plot outlines. The notes were sold by Bram Stoker's widow, Florence, in 1913, to a New York book dealer for £2.2s, (). Following that, the notes became the property of Charles Scribner's Sons, and then disappeared until they were bought by the Rosenbach Museum and Library in Philadelphia in 1970. H. P. Lovecraft wrote that he knew "an old lady" who was approached to revise the original manuscript, but that Stoker found her too expensive. Stoker's first biographer, Harry Ludlam, wrote in 1962 that writing commenced on Dracula around 1895 or 1896. Following the rediscovery of Stoker's notes in 1972 by Raymond T. McNally and Radu Florescu, the two dated the writing of Dracula from between 1895 and 1897. Later scholarship has questioned these sets of dates. In the first extensive study of the notes, Joseph S. Bierman writes that the earliest date within them is 8 March 1890, for an outline of a chapter that "differs from the final version in only a few details". According to Bierman, Stoker always intended to write an epistolary novel, but with an original setting of Styria instead of Transylvania; this iteration did not explicitly use the word vampire. For two summers, Stoker and his family stayed in the Kilmarnock Arms Hotel in Cruden Bay, Scotland, while he was actively writing Dracula. Stoker's notes illuminate much about earlier iterations of the novel. For instance, they indicate that the novel's vampire was intended to be a count, even before he was given the name Dracula. Stoker likely found the name Dracula in Whitby's public library while holidaying there with his wife and son in 1880. On the name, Stoker wrote: "Dracula means devil. Wallachians were accustomed to give it as a surname to any person who rendered himself conspicuous by courage, cruel actions or cunning". Stoker's initial plans for Dracula markedly differ from the final novel. Had Stoker completed his original plans, a German professor called Max Windshoeffel "would have confronted Count Wampyr from Styria", and one of the Crew of Light would have been slain by a werewolf. Stoker's earliest notes indicate that Dracula might have originally been intended to be a detective story, with a detective called Cotford and a psychical investigator called Singleton. Publication Dracula was published in London in May 1897 by Archibald Constable and Company. It cost 6 shillings, and was bound in yellow cloth and titled in red letters. In 2002, Barbara Belford, a biographer, wrote that the novel looked "shabby", perhaps because the title had been changed at a late stage. Although contracts were typically signed at least 6 months ahead of publication, Dracula was unusually signed only 6 days prior to publication. For the first thousand sales of the novel, Stoker earned no royalties. Following serialisation by American newspapers, Doubleday & McClure published an American edition in 1899. In the 1930s when Universal Studios purchased the rights to make a film version, it was discovered that Stoker had not fully complied with US copyright law, |
situation because he is faced with impending death if he fails to do so. Such a decision is not made on the basis of chance, but rather on necessity and spontaneity, given the prior predetermined events leading up to the predicament. Hume's argument is supported by modern-day compatibilists such as R. E. Hobart, a pseudonym of philosopher Dickinson S. Miller. However, P. F. Strawson argued that the issue of whether we hold one another morally responsible does not ultimately depend on the truth or falsity of a metaphysical thesis such as determinism. This is because our so holding one another is a non-rational human sentiment that is not predicated on such theses. Religion Philosopher Paul Russell (2005) contends that Hume wrote "on almost every central question in the philosophy of religion", and that these writings "are among the most important and influential contributions on this topic." Touching on the philosophy, psychology, history, and anthropology of religious thought, Hume's 1757 dissertation "The Natural History of Religion" argues that the monotheistic religions of Judaism, Christianity, and Islam all derive from earlier polytheistic religions. He went on to suggest that all religious belief "traces, in the end, to dread of the unknown". Hume had also written on religious subjects in the first Enquiry, as well as later in the Dialogues Concerning Natural Religion. Religious views Although he wrote a great deal about religion, Hume's personal views have been the subject of much debate. Some modern critics have described Hume's religious views as agnostic or have described him as a "Pyrrhonian skeptic". Contemporaries considered him to be an atheist, or at least un-Christian, enough so that the Church of Scotland seriously considered bringing charges of infidelity against him. Evidence of his un-Christian beliefs can especially be found in his writings on miracles, in which he attempts to separate historical method from the narrative accounts of miracles. The fact that contemporaries suspected him of atheism is exemplified by a story Hume liked to tell: The best theologian he ever met, he used to say, was the old Edinburgh fishwife who, having recognized him as Hume the atheist, refused to pull him out of the bog into which he had fallen until he declared he was a Christian and repeated the Lord's prayer. However, in works such as "Of Superstition and Enthusiasm", Hume specifically seems to support the standard religious views of his time and place. This still meant that he could be very critical of the Catholic Church, dismissing it with the standard Protestant accusations of superstition and idolatry, as well as dismissing as idolatry what his compatriots saw as uncivilised beliefs. He also considered extreme Protestant sects, the members of which he called "enthusiasts", to be corrupters of religion. By contrast, in "The Natural History of Religion", Hume presents arguments suggesting that polytheism had much to commend it over monotheism. Additionally, when mentioning religion as a factor in his History of England, Hume uses it to show the deleterious effect it has on human progress. In his Treatise of Human Nature, Hume wrote: "Generally speaking, the errors in religions are dangerous; those in philosophy only ridiculous." Paul Russell (2008) writes that Hume was plainly sceptical about religious belief, although perhaps not to the extent of complete atheism. He suggests that Hume's position is best characterised by the term "irreligion," while philosopher David O'Connor (2013) argues that Hume's final position was "weakly deistic". For O'Connor, Hume's "position is deeply ironic. This is because, while inclining towards a weak form of deism, he seriously doubts that we can ever find a sufficiently favourable balance of evidence to justify accepting any religious position." He adds that Hume "did not believe in the God of standard theism ... but he did not rule out all concepts of deity", and that "ambiguity suited his purposes, and this creates difficulty in definitively pinning down his final position on religion". Design argument One of the traditional topics of natural theology is that of the existence of God, and one of the a posteriori arguments for this is the argument from design or the teleological argument. The argument is that the existence of God can be proved by the design that is obvious in the complexity of the world, which Encyclopædia Britannica states is "the most popular", because it is:…the most accessible of the theistic arguments ... which identifies evidences of design in nature, inferring from them a divine designer ... The fact that the universe as a whole is a coherent and efficiently functioning system likewise, in this view, indicates a divine intelligence behind it.In An Enquiry Concerning Human Understanding, Hume wrote that the design argument seems to depend upon our experience, and its proponents "always suppose the universe, an effect quite singular and unparalleled, to be the proof of a Deity, a cause no less singular and unparalleled". Philosopher Louise E. Loeb (2010) notes that Hume is saying that only experience and observation can be our guide to making inferences about the conjunction between events. However, according to Hume: We observe neither God nor other universes, and hence no conjunction involving them. There is no observed conjunction to ground an inference either to extended objects or to God, as unobserved causes.Hume also criticised the argument in his Dialogues Concerning Natural Religion (1779). In this, he suggested that, even if the world is a more or less smoothly functioning system, this may only be a result of the "chance permutations of particles falling into a temporary or permanent self-sustaining order, which thus has the appearance of design". A century later, the idea of order without design was rendered more plausible by Charles Darwin's discovery that the adaptations of the forms of life result from the natural selection of inherited characteristics. For philosopher James D. Madden, it is "Hume, rivaled only by Darwin, [who] has done the most to undermine in principle our confidence in arguments from design among all figures in the Western intellectual tradition". Finally, Hume discussed a version of the anthropic principle, which is the idea that theories of the universe are constrained by the need to allow for man's existence in it as an observer. Hume has his sceptical mouthpiece Philo suggest that there may have been many worlds, produced by an incompetent designer, whom he called a "stupid mechanic". In his Dialogues Concerning Natural Religion, Hume wrote: Many worlds might have been botched and bungled throughout an eternity, ere this system was struck out: much labour lost: many fruitless trials made: and a slow, but continued improvement carried on during infinite ages in the art of world-making. American philosopher Daniel Dennett has suggested that this mechanical explanation of teleology, although "obviously ... an amusing philosophical fantasy", anticipated the notion of natural selection, the 'continued improvement' being like "any Darwinian selection algorithm". Problem of miracles In his discussion of miracles, Hume argues that we should not believe miracles have occurred and that they do not therefore provide us with any reason to think God exists. In An Enquiry Concerning Human Understanding (Section 10), Hume defines a miracle as "a transgression of a law of nature by a particular volition of the Deity, or by the interposition of some invisible agent". Hume says we believe an event that has frequently occurred is likely to occur again, but we also take into account those instances where the event did not occur: A wise man ... considers which side is supported by the greater number of experiments. ... A hundred instances or experiments on one side, and fifty on another, afford a doubtful expectation of any event; though a hundred uniform experiments, with only one that is contradictory, reasonably beget a pretty strong degree of assurance. In all cases, we must balance the opposite experiments ... and deduct the smaller number from the greater, in order to know the exact force of the superior evidence. Hume discusses the testimony of those who report miracles. He wrote that testimony might be doubted even from some great authority in case the facts themselves are not credible: "[T]he evidence, resulting from the testimony, admits of a diminution, greater or less, in proportion as the fact is more or less unusual." Although Hume leaves open the possibility for miracles to occur and be reported, he offers various arguments against this ever having happened in history. He points out that people often lie, and they have good reasons to lie about miracles occurring either because they believe they are doing so for the benefit of their religion or because of the fame that results. Furthermore, people by nature enjoy relating miracles they have heard without caring for their veracity and thus miracles are easily transmitted even when false. Also, Hume notes that miracles seem to occur mostly in "ignorant and barbarous nations" and times, and the reason they do not occur in the civilised societies is such societies are not awed by what they know to be natural events. Finally, the miracles of each religion argue against all other religions and their miracles, and so even if a proportion of all reported miracles across the world fit Hume's requirement for belief, the miracles of each religion make the other less likely. Hume was extremely pleased with his argument against miracles in his Enquiry. He states "I flatter myself, that I have discovered an argument of a like nature, which, if just, will, with the wise and learned, be an everlasting check to all kinds of superstitious delusion, and consequently, will be useful as long as the world endures." Thus, Hume's argument against miracles had a more abstract basis founded upon the scrutiny, not just primarily of miracles, but of all forms of belief systems. It is a common sense notion of veracity based upon epistemological evidence, and founded on a principle of rationality, proportionality and reasonability. The criterion for assessing Hume's belief system is based on the balance of probability whether something is more likely than not to have occurred. Since the weight of empirical experience contradicts the notion for the existence of miracles, such accounts should be treated with scepticism. Further, the myriad of accounts of miracles contradict one another, as some people who receive miracles will aim to prove the authority of Jesus, whereas others will aim to prove the authority of Muhammad or some other religious prophet or deity. These various differing accounts weaken the overall evidential power of miracles. Despite all this, Hume observes that belief in miracles is popular, and that "the gazing populace… receive greedily, without examination, whatever soothes superstition, and promotes wonder." Critics have argued that Hume's position assumes the character of miracles and natural laws prior to any specific examination of miracle claims, thus it amounts to a subtle form of begging the question. To assume that testimony is a homogeneous reference group seems unwise- to compare private miracles with public miracles, unintellectual observers with intellectual observers and those who have little to gain and much to lose with those with much to gain and little to lose is not convincing to many. Indeed, many have argued that miracles not only do not contradict the laws of nature, but require the laws of nature to be intelligible as miraculous, and thus subverting the law of nature. For example, William Adams remarks that "there must be an ordinary course of nature before anything can be extraordinary. There must be a stream before anything can be interrupted." They have also noted that it requires an appeal to inductive inference, as none have observed every part of nature nor examined every possible miracle claim, for instance those in the future. This, in Hume's philosophy, was especially problematic. Little appreciated is the voluminous literature either foreshadowing Hume, in the likes of Thomas Sherlock or directly responding to and engaging with Hume- from William Paley, William Adams, John Douglas, John Leland, and George Campbell, among others. Regarding the latter, it is rumoured that, having read Campbell's Dissertation, Hume remarked that "the Scotch theologue had beaten him." Hume's main argument concerning miracles is that miracles by definition are singular events that differ from the established laws of nature. Such natural laws are codified as a result of past experiences. Therefore, a miracle is a violation of all prior experience and thus incapable on this basis of reasonable belief. However, the probability that something has occurred in contradiction of all past experience should always be judged to be less than the probability that either ones senses have deceived one, or the person recounting the miraculous occurrence is lying or mistaken. Hume would say, all of which he had past experience of. For Hume, this refusal to grant credence does not guarantee correctness. He offers the example of an Indian Prince, who, having grown up in a hot country, refuses to believe that water has frozen. By Hume's lights, this refusal is not wrong and the Prince "reasoned justly;" it is presumably only when he has had extensive experience of the freezing of water that he has warrant to believe that the event could occur. So for Hume, either the miraculous event will become a recurrent event or else it will never be rational to believe it occurred. The connection to religious belief is left unexplained throughout, except for the close of his discussion where Hume notes the reliance of Christianity upon testimony of miraculous occurrences. He makes an ironic remark that anyone who "is moved by faith to assent" to revealed testimony "is conscious of a continued miracle in his own person, which subverts all principles of his understanding, and gives him a determination to believe what is most contrary to custom and experience." Hume writes that "All the testimony whichever was really given for any miracle, or ever will be given, is a subject of derision." As an historian of England From 1754 to 1762 Hume published The History of England, a six-volume work, that extends (according to its subtitle) "From the Invasion of Julius Caesar to the Revolution in 1688." Inspired by Voltaire's sense of the breadth of history, Hume widened the focus of the field away from merely kings, parliaments, and armies, to literature and science as well. He argued that the quest for liberty was the highest standard for judging the past, and concluded that after considerable fluctuation, England at the time of his writing had achieved "the most entire system of liberty that was ever known amongst mankind". It "must be regarded as an event of cultural importance. In its own day, moreover, it was an innovation, soaring high above its very few predecessors." Hume's History of England made him famous as a historian before he was ever considered a serious philosopher. In this work, Hume uses history to tell the story of the rise of England and what led to its greatness and the disastrous effects that religion has had on its progress. For Hume, the history of England's rise may give a template for others who would also like to rise to its current greatness. Hume's The History of England was profoundly impacted by his Scottish background. The science of sociology, which is rooted in Scottish thinking of the eighteenth century, had never before been applied to British philosophical history. Because of his Scottish background, Hume was able to bring an outsider's lens to English history that the insulated English whigs lacked. Hume's coverage of the political upheavals of the 17th century relied in large part on the Earl of Clarendon's History of the Rebellion and Civil Wars in England (1646–69). Generally, Hume took a moderate royalist position and considered revolution unnecessary to achieve necessary reform. Hume was considered a Tory historian, and emphasised religious differences more than constitutional issues. Laird Okie explains that "Hume preached the virtues of political moderation, but ... it was moderation with an anti-Whig, pro-royalist coloring." For "Hume shared the ... Tory belief that the Stuarts were no more high-handed than their Tudor predecessors". "Even though Hume wrote with an anti-Whig animus, it is, paradoxically, correct to regard the History as an establishment work, one which implicitly endorsed the ruling oligarchy". Historians have debated whether Hume posited a universal unchanging human nature, or allowed for evolution and development. The debate between Tory and the Whig historians can be seen in the initial reception to Hume's History of England. The whig-dominated world of 1754 overwhelmingly disapproved of Hume's take on English history. In later editions of the book, Hume worked to "soften or expunge many villainous whig strokes which had crept into it." Hume did not consider himself a pure Tory. Before 1745, he was more akin to an "independent whig." In 1748, he described himself as "a whig, though a very skeptical one." This description of himself as in between whiggism and toryism, helps one understand that his History of England should be read as his attempt to work out his own philosophy of history. Robert Roth argues that Hume's histories display his biases against Presbyterians and Puritans. Roth says his anti-Whig pro-monarchy position diminished the influence of his work, and that his emphasis on politics and religion led to a neglect of social and economic history. Hume was an early cultural historian of science. His short biographies of leading scientists explored the process of scientific change. He developed new ways of seeing scientists in the context of their times by looking at how they interacted with society and each other. He covers over forty scientists, with special attention paid to Francis Bacon, Robert Boyle, and Isaac Newton. Hume particularly praised William Harvey, writing about his treatise of the circulation of the blood: "Harvey is entitled to the glory of having made, by reasoning alone, without any mixture of accident, a capital discovery in one of the most important branches of science." The History became a best-seller and made Hume a wealthy man who no longer had to take up salaried work for others. It was influential for nearly a century, despite competition from imitations by Smollett (1757), Goldsmith (1771) and others. By 1894, there were at least 50 editions as well as abridgements for students, and illustrated pocket editions, probably produced specifically for women. Political theory Hume's writings have been described as largely seminal to conservative theory, and he is considered a founding father of conservatism. Many of his ideas, such as limited government, private property when there is scarcity, and constitutionalism, are first principles of conservative political parties around the world. Thomas Jefferson banned the History from University of Virginia, feeling that it had "spread universal toryism over the land." By comparison, Samuel Johnson thought Hume to be "a Tory by chance [...] for he has no principle. If he is anything, he is a Hobbist." A major concern of Hume's political philosophy is the importance of the rule of law. He also stresses throughout his political essays the importance of moderation in politics, public spirit, and regard to the community. Throughout the period of the American Revolution, Hume had varying views. For instance, in 1768 he encouraged total revolt on the part of the Americans. In 1775, he became certain that a revolution would take place and said that he believed in the American principle and wished the British government would let them be. Hume's influence on some of the Founders can be seen in Benjamin Franklin's suggestion at the Philadelphia Convention of 1787 that no high office in any branch of government should receive a salary, which is a suggestion Hume had made in his emendation of James Harrington's Oceana. The legacy of religious civil war in 18th-century Scotland, combined with the relatively recent memory of the 1715 and 1745 Jacobite risings, had fostered in Hume a distaste for enthusiasm and factionalism. These appeared to him to threaten the fragile and nascent political and social stability of a country that was deeply politically and religiously divided. Hume thought that society is best governed by a general and impartial system of laws; he is less concerned about the form of government that administers these laws, so long as it does so fairly. However, he also clarified that a republic must produce laws, while "monarchy, when absolute, contains even something repugnant to law." Hume expressed suspicion of attempts to reform society in ways that departed from long-established custom, and he counselled peoples not to resist their governments except in cases of the most egregious tyranny. However, he resisted aligning himself with either of Britain's two political parties, the Whigs and the Tories: My views of things are more conformable to Whig principles; my representations of persons to Tory prejudices. Canadian philosopher Neil McArthur writes that Hume believed that we should try to balance our demands for liberty with the need for strong authority, without sacrificing either. McArthur characterises Hume as a "precautionary conservative," whose actions would have been "determined by prudential concerns about the consequences of change, which often demand we ignore our own principles about what is ideal or even legitimate." Hume supported the liberty of the press, and was sympathetic to democracy, when suitably constrained. American historian Douglass Adair has argued that | conceive an idea of the physical flower because the idea of the illustrated object is associated with the physical object's idea. The principle of contiguity describes the tendency of ideas to become associated if the objects they represent are near to each other in time or space, such as when the thought of a crayon in a box leads one to think of the crayon contiguous to it. The principle of cause and effect refers to the tendency of ideas to become associated if the objects they represent are causally related, which explains how remembering a broken window can make someone think of a ball that had caused the window to shatter. Hume elaborates more on the last principle, explaining that, when somebody observes that one object or event consistently produces the same object or event, that results in "an expectation that a particular event (a 'cause') will be followed by another event (an 'effect') previously and constantly associated with it". Hume calls this principle custom, or habit, saying that "custom...renders our experience useful to us, and makes us expect, for the future, a similar train of events with those which have appeared in the past". However, even though custom can serve as a guide in life, it still only represents an expectation. In other words: Experience cannot establish a necessary connection between cause and effect, because we can imagine without contradiction a case where the cause does not produce its usual effect…the reason why we mistakenly infer that there is something in the cause that necessarily produces its effect is because our past experiences have habituated us to think in this way. Continuing this idea, Hume argues that "only in the pure realm of ideas, logic, and mathematics, not contingent on the direct sense awareness of reality, [can] causation safely…be applied—all other sciences are reduced to probability". He uses this scepticism to reject metaphysics and many theological views on the basis that they are not grounded in fact and observations, and are therefore beyond the reach of human understanding. Induction and causation The cornerstone of Hume's epistemology is the problem of induction. This may be the area of Hume's thought where his scepticism about human powers of reason is most pronounced. The problem revolves around the plausibility of inductive reasoning, that is, reasoning from the observed behaviour of objects to their behaviour when unobserved. As Hume wrote, induction concerns how things behave when they go "beyond the present testimony of the senses, or the records of our memory". Hume argues that we tend to believe that things behave in a regular manner, meaning that patterns in the behaviour of objects seem to persist into the future, and throughout the unobserved present. Hume's argument is that we cannot rationally justify the claim that nature will continue to be uniform, as justification comes in only two varieties—demonstrative reasoning and probable reasoning—and both of these are inadequate. With regard to demonstrative reasoning, Hume argues that the uniformity principle cannot be demonstrated, as it is "consistent and conceivable" that nature might stop being regular. Turning to probable reasoning, Hume argues that we cannot hold that nature will continue to be uniform because it has been in the past. As this is using the very sort of reasoning (induction) that is under question, it would be circular reasoning. Thus, no form of justification will rationally warrant our inductive inferences. Hume's solution to this problem is to argue that, rather than reason, natural instinct explains the human practice of making inductive inferences. He asserts that "Nature, by an absolute and uncontroulable [sic] necessity has determin'd us to judge as well as to breathe and feel." In 1985, and in agreement with Hume, John D. Kenyon writes: Reason might manage to raise a doubt about the truth of a conclusion of natural inductive inference just for a moment ... but the sheer agreeableness of animal faith will protect us from excessive caution and sterile suspension of belief.Others, such as Charles Sanders Peirce, have demurred from Hume's solution, while some, such as Kant and Karl Popper, have thought that Hume's analysis has "posed a most fundamental challenge to all human knowledge claims". The notion of causation is closely linked to the problem of induction. According to Hume, we reason inductively by associating constantly conjoined events. It is the mental act of association that is the basis of our concept of causation. At least three interpretations of Hume's theory of causation are represented in the literature: the logical positivist; the sceptical realist; and the quasi-realist. Hume acknowledged that there are events constantly unfolding, and humanity cannot guarantee that these events are caused by prior events or are independent instances. He opposed the widely accepted theory of causation that 'all events have a specific course or reason'. Therefore, Hume crafted his own theory of causation, formed through his empiricist and sceptic beliefs. He split causation into two realms: "All the objects of human reason or enquiry may naturally be divided into two kinds, to wit, Relations of Ideas, and Matters of Fact." Relations of Ideas are a priori and represent universal bonds between ideas that mark the cornerstones of human thought. Matters of Fact are dependent on the observer and experience. They are often not universally held to be true among multiple persons. Hume was an Empiricist, meaning he believed "causes and effects are discoverable not by reason, but by experience". He goes on to say that, even with the perspective of the past, humanity cannot dictate future events because thoughts of the past are limited, compared to the possibilities for the future. Hume's separation between Matters of Fact and Relations of Ideas is often referred to as "Hume's fork." Hume explains his theory of causation and causal inference by division into three different parts. In these three branches he explains his ideas and compares and contrasts his views to his predecessors. These branches are the Critical Phase, the Constructive Phase, and Belief. In the Critical Phase, Hume denies his predecessors' theories of causation. Next, he uses the Constructive Phase to resolve any doubts the reader may have had while observing the Critical Phase. "Habit or Custom" mends the gaps in reasoning that occur without the human mind even realising it. Associating ideas has become second nature to the human mind. It "makes us expect for the future, a similar train of events with those which have appeared in the past". However, Hume says that this association cannot be trusted because the span of the human mind to comprehend the past is not necessarily applicable to the wide and distant future. This leads him to the third branch of causal inference, Belief. Belief is what drives the human mind to hold that expectancy of the future is based on past experience. Throughout his explanation of causal inference, Hume is arguing that the future is not certain to be repetition of the past and that the only way to justify induction is through uniformity. The logical positivist interpretation is that Hume analyses causal propositions, such as "A causes B", in terms of regularities in perception: "A causes B" is equivalent to "Whenever A-type events happen, B-type ones follow", where "whenever" refers to all possible perceptions. In his Treatise of Human Nature, Hume wrote: Power and necessity…are…qualities of perceptions, not of objects…felt by the soul and not perceiv'd externally in bodies. This view is rejected by sceptical realists, who argue that Hume thought that causation amounts to more than just the regular succession of events. Hume said that, when two events are causally conjoined, a necessary connection underpins the conjunction: Shall we rest contented with these two relations of contiguity and succession, as affording a complete idea of causation? By no means…there is a necessary connexion to be taken into consideration. Angela Coventry writes that, for Hume, "there is nothing in any particular instance of cause and effect involving external objects which suggests the idea of power or necessary connection" and "we are ignorant of the powers that operate between objects". However, while denying the possibility of knowing the powers between objects, Hume accepted the causal principle, writing: "I never asserted so absurd a proposition as that something could arise without a cause." It has been argued that, while Hume did not think that causation is reducible to pure regularity, he was not a fully fledged realist either. Simon Blackburn calls this a quasi-realist reading, saying that "Someone talking of cause is voicing a distinct mental set: he is by no means in the same state as someone merely describing regular sequences." In Hume's words, "nothing is more usual than to apply to external bodies every internal sensation, which they occasion". The 'self' Empiricist philosophers, such as Hume and Berkeley, favoured the bundle theory of personal identity. In this theory, "the mind itself, far from being an independent power, is simply 'a bundle of perceptions' without unity or cohesive quality". The self is nothing but a bundle of experiences linked by the relations of causation and resemblance; or, more accurately, the empirically warranted idea of the self is just the idea of such a bundle. According to Hume: This view is supported by, for example, positivist interpreters, who have seen Hume as suggesting that terms such as "self", "person", or "mind" refer to collections of "sense-contents". A modern-day version of the bundle theory of the mind has been advanced by Derek Parfit in his Reasons and Persons. However, some philosophers have criticised Hume's bundle-theory interpretation of personal identity. They argue that distinct selves can have perceptions that stand in relation to similarity and causality. Thus, perceptions must already come parcelled into distinct "bundles" before they can be associated according to the relations of similarity and causality. In other words, the mind must already possess a unity that cannot be generated, or constituted, by these relations alone. Since the bundle-theory interpretation portrays Hume as answering an ontological question, philosophers like Galen Strawson see Hume as not very concerned with such questions and have queried whether this view is really Hume's. Instead, Strawson suggests that Hume might have been answering an epistemological question about the causal origin of our concept of the self. In the Appendix to the Treatise, Hume declares himself dissatisfied with his earlier account of personal identity in Book 1. Corliss Swain notes that "Commentators agree that if Hume did find some new problem" when he reviewed the section on personal identity, "he wasn't forthcoming about its nature in the Appendix." One interpretation of Hume's view of the self, argued for by philosopher and psychologist James Giles, is that Hume is not arguing for a bundle theory, which is a form of reductionism, but rather for an eliminative view of the self. Rather than reducing the self to a bundle of perceptions, Hume rejects the idea of the self altogether. On this interpretation, Hume is proposing a "no-self theory" and thus has much in common with Buddhist thought (see anattā). Psychologist Alison Gopnik has argued that Hume was in a position to learn about Buddhist thought during his time in France in the 1730s. Practical reason Practical reason relates to whether standards or principles exist that are also authoritative for all rational beings, dictating people's intentions and actions. Hume is mainly considered an anti-rationalist, denying the possibility for practical reason, although other philosophers such as Christine Korsgaard, Jean Hampton, and Elijah Millgram claim that Hume is not so much of an anti-rationalist as he is just a sceptic of practical reason. Hume denied the existence of practical reason as a principle because he claimed reason does not have any effect on morality, since morality is capable of producing effects in people that reason alone cannot create. As Hume explains in A Treatise of Human Nature (1740): Morals excite passions, and produce or prevent actions. Reason of itself is utterly impotent in this particular. The rules of morality, therefore, are not conclusions of our reason."Since practical reason is supposed to regulate our actions (in theory), Hume denied practical reason on the grounds that reason cannot directly oppose passions. As Hume puts it, "Reason is, and ought only to be the slave of the passions, and can never pretend to any other office than to serve and obey them." Reason is less significant than any passion because reason has no original influence, while "A passion is an original existence, or, if you will, modification of existence." Practical reason is also concerned with the value of actions rather than the truth of propositions, so Hume believed that reason's shortcoming of affecting morality proved that practical reason could not be authoritative for all rational beings, since morality was essential for dictating people's intentions and actions. Ethics Hume's writings on ethics began in the 1740 Treatise and were refined in his An Enquiry Concerning the Principles of Morals (1751). He understood feeling, rather than knowing, as that which governs ethical actions, stating that "moral decisions are grounded in moral sentiment." Arguing that reason cannot be behind morality, he wrote: Morals excite passions, and produce or prevent actions. Reason itself is utterly impotent in this particular. The rules of morality, therefore, are not conclusions of our reason. Hume's moral sentimentalism was shared by his close friend Adam Smith, and the two were mutually influenced by the moral reflections of their older contemporary, Francis Hutcheson. Peter Singer claims that Hume's argument that morals cannot have a rational basis alone "would have been enough to earn him a place in the history of ethics." Hume also put forward the is–ought problem, later known as Hume's Law, denying the possibility of logically deriving what ought to be from what is. According to the Treatise (1740), in every system of morality that Hume has read, the author begins by stating facts about the world as it is but always ends up suddenly referring to what ought to be the case. Hume demands that a reason should be given for inferring what ought to be the case, from what is the case. This is because it "seems altogether inconceivable, how this new relation can be a deduction from others." Hume's theory of ethics has been influential in modern-day meta-ethical theory, helping to inspire emotivism, and ethical expressivism and non-cognitivism, as well as Allan Gibbard's general theory of moral judgment and judgments of rationality. Aesthetics Hume's ideas about aesthetics and the theory of art are spread throughout his works, but are particularly connected with his ethical writings, and also the essays "Of the Standard of Taste" and "Of Tragedy" (1757). His views are rooted in the work of Joseph Addison and Francis Hutcheson. In the Treatise (1740), he touches on the connection between beauty & deformity and vice & virtue. His later writings on the subject continue to draw parallels of beauty and deformity in art with conduct and character. In "Standard of Taste", Hume argues that no rules can be drawn up about what is a tasteful object. However, a reliable critic of taste can be recognised as objective, sensible and unprejudiced, and as having extensive experience. "Of Tragedy" addresses the question of why humans enjoy tragic drama. Hume was concerned with the way spectators find pleasure in the sorrow and anxiety depicted in a tragedy. He argued that this was because the spectator is aware that he is witnessing a dramatic performance. There is pleasure in realising that the terrible events that are being shown are actually fiction. Furthermore, Hume laid down rules for educating people in taste and correct conduct, and his writings in this area have been very influential on English and Anglo-Saxon aesthetics. Free will, determinism, and responsibility Hume, along with Thomas Hobbes, is cited as a classical compatibilist about the notions of freedom and determinism. Compatibilism seeks to reconcile human freedom with the mechanist view that human beings are part of a deterministic universe, which is completely governed by physical laws. Hume, on this point, was influenced greatly by the scientific revolution, particularly by Sir Isaac Newton. Hume argued that the dispute between freedom and determinism continued over 2000 years due to ambiguous terminology. He wrote: "From this circumstance alone, that a controversy has been long kept on foot…we may presume that there is some ambiguity in the expression," and that different disputants use different meanings for the same terms. Hume defines the concept of necessity as "the uniformity, observable in the operations of nature; where similar objects are constantly conjoined together," and liberty as "a power of acting or not acting, according to the determinations of the will." He then argues that, according to these definitions, not only are the two compatible, but liberty requires necessity. For if our actions were not necessitated in the above sense, they would "have so little in connexion with motives, inclinations and circumstances, that one does not follow with a certain degree of uniformity from the other." But if our actions are not thus connected to the will, then our actions can never be free: they would be matters of "chance; which is universally allowed to have no existence." Australian philosopher John Passmore writes that confusion has arisen because "necessity" has been taken to mean "necessary connexion." Once this has been abandoned, Hume argues that "liberty and necessity will be found not to be in conflict one with another." Moreover, Hume goes on to argue that in order to be held morally responsible, it is required that our behaviour be caused or necessitated, for, as he wrote: Actions are, by their very nature, temporary and perishing; and where they proceed not from some cause in the character and disposition of the person who performed them, they can neither redound to his honour, if good; nor infamy, if evil. Hume describes the link between causality and our capacity to rationally make a decision from this an inference of the mind. Human beings assess a situation based upon certain predetermined events and from that form a choice. Hume believes that this choice is made spontaneously. Hume calls this form of decision making the liberty of spontaneity. Education writer Richard Wright considers that Hume's position rejects a famous moral puzzle attributed to French philosopher Jean Buridan. The Buridan's ass puzzle describes a donkey that is hungry. This donkey has separate bales of hay on both sides, which are of equal distances from him. The problem concerns which bale the donkey chooses. Buridan was said to believe that the donkey would die, because he has no autonomy. The donkey is incapable of forming a rational decision as there is no motive to choose one bale of hay over the other. However, human beings are different, because a human who is placed in a position where he is forced to choose one loaf of bread over another will make a decision to take one in lieu of the other. For Buridan, humans have the capacity of autonomy, and he recognises the choice that is ultimately made will be based on chance, as both loaves of bread are exactly the same. However, Wright says that Hume completely rejects this notion, arguing that a human will spontaneously act in such a situation because he is faced with impending death if he fails to do so. Such a decision is not made on the basis of chance, but rather on necessity and spontaneity, given the prior predetermined events leading up to the predicament. Hume's argument is supported by modern-day compatibilists such as R. E. Hobart, a pseudonym of philosopher Dickinson S. Miller. However, P. F. Strawson argued that the issue of whether we hold one another morally responsible does not ultimately depend on the truth or falsity of a metaphysical thesis such as determinism. This is because our so holding one another is a non-rational human sentiment that is not predicated on such theses. Religion Philosopher Paul Russell (2005) contends that Hume wrote "on almost every central question in the philosophy of religion", and that these writings "are among the most important and influential contributions on this topic." Touching on the philosophy, psychology, history, and anthropology of religious thought, Hume's 1757 dissertation "The Natural History of Religion" argues that the monotheistic religions of Judaism, Christianity, and Islam all derive from earlier polytheistic religions. He went on to suggest that all religious belief "traces, in |
Communist Party in 1943, and remained active until 1947. He reaffiliated himself with the party in 1954. His novel The Remarkable Andrew featured the ghost of President Andrew Jackson appearing to caution the United States against getting involved in World War II and in support of the Nazi-Soviet pact. Shortly after the Operation Barbarossa, the German invasion of the Soviet Union in 1941, Trumbo and his publisher decided to suspend reprinting Johnny Got His Gun until the end of the war. During the war, Trumbo received letters from individuals "denouncing Jews" and using Johnny to support their arguments for "an immediate negotiated peace" with Nazi Germany; Trumbo reported these correspondents to the FBI. Trumbo regretted this decision, which he called "foolish". After two FBI agents showed up at his home, he understood that "their interest lay not in the letters but in me". In a 1946 article titled "The Russian Menace" published in Rob Wagner's Script Magazine, Trumbo wrote from the perspective of a post-World War II Russian citizen. He argued that Russians were likely fearful of the mass of U.S. military power that surrounded them, at a time when any sympathetic view toward Communist countries was viewed with suspicion. He ended the article by stating, "If I were a Russian ... I would be alarmed, and I would petition my government to take measures at once against what would seem an almost certain blow aimed at my existence. This is how it must appear in Russia today". He argued that the U.S. was a "menace" to Russia, rather than the more popular American view of Russia as the "red menace". According to anti-Communist author Kenneth Billingsley, Trumbo had written in The Daily Worker that Communist influence in Hollywood had prevented films from being made from anti-Communist books, such as Arthur Koestler's Darkness at Noon and The Yogi and the Commissar. William R. Wilkerson, publisher and founder of The Hollywood Reporter, published a July 29, 1946 "TradeView" column entitled "A Vote For Joe Stalin". It named Trumbo and several others as Communist sympathizers, the first persons identified on what became known as "Billy's Blacklist". In October 1947, drawing upon these names, the House Un-American Activities Committee (HUAC) summoned Trumbo and nine others to testify for their investigation as to whether Communist agents and sympathizers had surreptitiously planted propaganda in U.S. films. The writers refused to give information about their own or any other person's involvement and were convicted for contempt of Congress. They appealed the conviction to the Supreme Court on First Amendment grounds and lost. Trumbo served eleven months in the federal penitentiary in Ashland, Kentucky in 1950. In the 1976 documentary Hollywood On Trial, Trumbo said: "As far as I was concerned, it was a completely just verdict. I had contempt for that Congress and have had contempt for it ever since. And on the basis of guilt or innocence, I could never really complain very much. That this was a crime or misdemeanor was the complaint, my complaint." The MPAA issued a statement that Trumbo and his compatriots would not be permitted to work in the industry unless they disavowed Communism under oath. After completing his sentence, Trumbo sold his ranch and moved his family to Mexico City with Hugo Butler and his wife Jean Rouverol, who had also been blacklisted. In Mexico, Trumbo wrote 30 scripts (under pseudonyms) for B-movie studios such as King Brothers Productions. In the case of Gun Crazy (1950), adapted from a short story by MacKinlay Kantor, Kantor agreed to be the front for Trumbo's screenplay. Trumbo's role in the screenplay was not revealed until 1992. During this blacklist period, Trumbo also wrote The Brave One (1956) for the King Brothers. Like Roman Holiday, it received an Academy Award for Best Story he could not claim. The script was credited to Robert Rich, a name borrowed from a nephew of the producers. Trumbo recalled earning an average fee of $1,750 per film for 18 screenplays written in two years and said, "None was very good". He published The Devil | Kantor agreed to be the front for Trumbo's screenplay. Trumbo's role in the screenplay was not revealed until 1992.

He published The Devil in the Book, an analysis of the conviction of 14 California Smith Act defendants, in 1956. The statute set criminal penalties for advocating the overthrow of the U.S. government and required all non-citizen adult residents to register with the government. Later career Gradually the blacklist weakened. With the support of director Otto Preminger, Trumbo was credited for the screenplay of the film Exodus (1960), adapted from the novel of the same name by Leon Uris. Shortly thereafter, actor Kirk Douglas announced Trumbo had written the screenplay for Stanley Kubrick's film Spartacus (also 1960), adapted from the novel by Howard Fast. With these actions, Preminger and Douglas helped end the power of the blacklist. Trumbo was reinstated into the Writers Guild of America, West and was credited on all subsequent scripts. The guild finally gave him full credit for the script of the 1953 film Roman Holiday in 2011. Trumbo directed the 1971 film adaptation of his novel Johnny Got His Gun, starring Timothy Bottoms, Diane Varsi, Jason Robards and Donald Sutherland. One of the last films Trumbo wrote, Executive Action (1973), was based on the Kennedy assassination. The Academy officially recognized Trumbo as the winner of the Oscar for the 1956 film The Brave One in 1975, presenting him with a statuette. Personal life In 1938, Trumbo married Cleo Fincher, who was born in Fresno, California on July 17, 1916 and had moved with her divorced mother and her brother and sister to Los Angeles. The Trumbos had three children: Nikola Trumbo (1939), who became a psychotherapist; Christopher Trumbo (1940), a filmmaker and screenwriter who became an expert on the Hollywood blacklist; and Melissa Trumbo (1945), known as Mitzi, a photographer. Mitzi Trumbo dated comedian Steve Martin when they were both in their early 20s, which is recounted in Martin's 2007 book Born Standing Up. Martin wrote of her: "Mitzi became my official photographer, and she snapped dozens of rolls of film, all to find the perfect publicity photo." Cleo Trumbo died of natural causes at the age of 93 on October 9, 2009 at the home she shared with Mitzi Trumbo in Los Altos, California. Death and legacy Trumbo died in Los Angeles of a heart attack at the age of 70 on September 10, 1976. He donated his body to scientific research. In 1993, Trumbo was posthumously awarded the Academy Award for writing Roman Holiday (1953). The screen credit and award were previously given to Ian McLellan Hunter, who had been a front for Trumbo. A new statue was made for this award because Hunter's son refused to hand over the one his father had received. In 2003, Christopher Trumbo mounted an Off-Broadway play based on his father's letters, called Trumbo: Red, White and Blacklisted, in which a wide variety of actors played his father during the run, including Nathan Lane, Tim Robbins, Brian Dennehy, Ed Harris, Chris Cooper and Gore Vidal. He adapted it as the documentary Trumbo (2007), which added archival footage and new interviews. A dramatization of Trumbo's life, also called Trumbo, was released in November 2015. It starred Bryan Cranston in the title role and was directed by Jay Roach. For his portrayal of Trumbo, Cranston was nominated for Best Actor at the 88th Academy Awards. The moving image collection of Trumbo is held at the Academy Film Archive and consists primarily of extensive 35 mm production materials relating to the 1971 anti-war film Johnny Got His Gun. More than a hundred years after his birth, Trumbo was honored by the installation of a statue of him in front of the Avalon Theater on Main Street in Grand Junction, Colorado, his home town. He was depicted writing a screenplay in a bathtub.

the 15th Amendment was rejected on March 18, 1869. Delaware officially ratified the 13th, 14th, and 15th amendments on February 12, 1901. Reconstruction and industrialization After the Civil War, Democratic governments led by the state's Bourbon aristocracy continued to dominate the state and imposed an explicitly white supremacist regime in the state. The Democratic legislatures declared blacks second-class citizens in 1866 and restricted their voting rights despite the Fifteenth Amendment, ensuring continued Democratic success throughout most of the nineteenth century. Beginning in the late nineteenth century, the Wilmington area grew into a manufacturing center. Investment in manufacturing in the city grew from $5.5 million in 1860 to $44 million in 1900. The most notable manufacturer in the state was the Du Pont Company. Because of Wilmington's growth, local politicians from the city and New Castle County pressured the state government to adopt a new constitution providing the north with more representation. However, the subsequent 1897 constitution did not proportionally represent the north and continued to give the southern counties disproportionate influence. As manufacturing expanded, businesses became major players in state affairs and funders of politicians through families such as the Du Ponts. Republican John Addicks attempted to buy a US Senate seat multiple times in a rivalry with the Du Ponts until the passage of the Seventeenth Amendment. The allegiance of industries with the Republican party allowed them to gain control of the state's governorship throughout most of the twentieth century. The GOP ensured blacks could vote because of their general support for Republicans and thus undid restrictions on black suffrage. Delaware benefited greatly from World War I because of the state's large gunpowder industry. The Du Pont Company, the most dominant business in the state by WWI, produced an estimated 40% of all gunpowder used by the Allies during the war. It produced nylon in the state after the war and began investments into General Motors. Additionally, the company invested heavily in the expansion of public schools in the state and colleges such as the University of Delaware in the 1910s and 1920s. This included primary and secondary schools for blacks and women. Delaware suffered less during the Great Depression than other states, but the depression spurred further migration from the rural south to urban areas. World War II to present Like in World War I, the state enjoyed a big stimulus to its gunpowder and shipyard industries in World War II. New job opportunities during and after the war in the Wilmington area coaxed African Americans from the southern counties to move to the city. The proportion of blacks constituting the city's population rose from 15% in 1950 to over 50% by 1980. The surge of black migrants to the north sparked white flight in which middle class whites moved from the city to suburban areas, leading to general segregation of Delaware's society. In the 1940s and 1950s, the state attempted to integrate its schools. The University of Delaware admitted its first black student in 1948, and local courts ruled that primary schools had to be integrated. Delaware's integration efforts partially inspired the US Supreme Court's decision in Brown v. Board of Education. However, integration only encouraged more white flight, and poor economic conditions for the black population led to some violence during the 1960s. Riots broke out in Wilmington in 1967 and again in 1968 in response to the assassination of Martin Luther King Jr after which the National Guard occupied the city for nine months to prevent further violence. Since WWII, the state has been generally economically prosperous and enjoyed relatively high per capita income because of its location between major cities like Philadelphia, New York, and Washington, DC. Its population grew rapidly, particularly in the suburbs in the north where New Castle county became an extension of the Philadelphia metropolitan area. Americans, including migrants from Puerto Rico, and immigrants from Latin America flocked to the state. By 1990, only 50% of Delaware's population consisted of natives to the state. Geography Delaware is long and ranges from to across, totaling , making it the second-smallest state in the United States after Rhode Island. Delaware is bounded to the north by Pennsylvania; to the east by the Delaware River, Delaware Bay, New Jersey and the Atlantic Ocean; and to the west and south by Maryland. Small portions of Delaware are also situated on the eastern side of the Delaware River sharing land boundaries with New Jersey. The state of Delaware, together with the Eastern Shore counties of Maryland and two counties of Virginia, form the Delmarva Peninsula, which stretches down the Mid-Atlantic Coast. The definition of the northern boundary of the state is unusual. Most of the boundary between Delaware and Pennsylvania was originally defined by an arc extending from the cupola of the courthouse in the city of New Castle. This boundary is often referred to as the Twelve-Mile Circle. Although the Twelve-Mile Circle is often claimed to be the only territorial boundary in the U.S. that is a true arc, the Mexican boundary with Texas includes several arcs, and many cities in the South (such as Plains, Georgia) also have circular boundaries. This border extends all the way east to the low-tide mark on the New Jersey shore, then continues south along the shoreline until it again reaches the arc in the south; then the boundary continues in a more conventional way in the middle of the main channel (thalweg) of the Delaware River. To the west, a portion of the arc extends past the easternmost edge of Maryland. The remaining western border runs slightly east of due south from its intersection with the arc. The Wedge of land between the northwest part of the arc and the Maryland border was claimed by both Delaware and Pennsylvania until 1921, when Delaware's claim was confirmed. Topography Delaware is on a level plain, with the lowest mean elevation of any state in the nation. Its highest elevation, located at Ebright Azimuth, near Concord High School, is less than above sea level. The northernmost part of the state is part of the Piedmont Plateau with hills and rolling surfaces. The Atlantic Seaboard fall line approximately follows the Robert Kirkwood Highway between Newark and Wilmington; south of this road is the Atlantic Coastal Plain with flat, sandy, and, in some parts, swampy ground. A ridge about high extends along the western boundary of the state and separates the watersheds that feed Delaware River and Bay to the east and the Chesapeake Bay to the west. Climate Since almost all of Delaware is a part of the Atlantic coastal plain, the effects of the ocean moderate its climate. The state lies in the humid subtropical climate (Köppen Cfa) zone. Despite its small size (roughly from its northernmost to southernmost points), there is significant variation in mean temperature and amount of snowfall between Sussex County and New Castle County. Moderated by the Atlantic Ocean and Delaware Bay, the southern portion of the state has a milder climate and a longer growing season than the northern portion of the state. Delaware's all-time record high of was recorded at Millsboro on July 21, 1930. The all-time record low of was also recorded at Millsboro, on January 17, 1893. The hardiness zones are 7a and 7b. Environment The transitional climate of Delaware supports a wide variety of vegetation. In the northern third of the state are found Northeastern coastal forests and mixed oak forests typical of the northeastern United States. In the southern two-thirds of the state are found Middle Atlantic coastal forests. Trap Pond State Park, along with areas in other parts of Sussex County, for example, support the northernmost stands of bald cypress trees in North America. Environmental management Delaware provides government subsidy support for the clean-up of property "lightly contaminated" by hazardous waste, the proceeds for which come from a tax on wholesale petroleum sales. Municipalities Wilmington is the state's most populous city (70,635) and its economic hub. It is located within commuting distance of both Philadelphia and Baltimore. Dover is the state capital and the second most populous city (38,079).

Demographics The United States Census Bureau determined that the population of Delaware was 989,948 on April 1, 2020, an increase since the 2010 United States census at 897,934. Delaware's history as a border state has led it to exhibit characteristics of both the Northern and the Southern regions of the United States. Generally, the rural Southern (or "Slower Lower") regions of Delaware below the Chesapeake and Delaware Canal embody a Southern culture, while densely-populated Northern Delaware above the canal—particularly Wilmington, a part of the Philadelphia metropolitan area—has more in common with that of the Northeast. The U.S. Census Bureau designates Delaware as one of the South Atlantic States, but it is commonly associated with the Mid-Atlantic States and/or northeastern United States by other federal agencies, the media, and some residents. Delaware is the sixth most densely populated state, with a population density of 442.6 people per square mile, 356.4 per square mile more than the national average, and ranking 45th in population. Delaware is one of five U.S. states (Maine, Vermont, West Virginia, Wyoming) that do not have a single city with a population over 100,000 as of the 2010 census. The center of population of Delaware is in New Castle County, in the town of Townsend. , 49.7% of Delaware's population younger than one year of age belonged to minority groups (i.e., did not have two parents of non-Hispanic white ancestry). In 2000 approximately 19% of the population were African-American and 5% of the population is Hispanic (mostly of Puerto Rican or Mexican ancestry). Race and ethnicity According to the 2010 United States census, the racial composition of the state was 68.9% White American (65.3% Non-Hispanic White, 3.6% White Hispanic), 21.4% Black or African American, 0.5% American Indian and Alaska Native, 3.2% Asian American, 0.0% Native Hawaiian and other Pacific Islander, 3.4% some other race, and 2.7% Multiracial American. Ethnically, Hispanics and Latin Americans of any race made up 8.2% of the population. The 2019 American Community Survey estimated the state had a racial and ethnic makeup of 61.% non-Hispanic whites, 23.2% Black or African American, 0.7% American Indian or Alaska Native, 4.1% Asian, 0.1% Pacific Islander, 2.7% multiracial, and 9.6% Hispanic or Latin American of any race. In the Native American community, the state has a Native American group (called in their own language Lenni Lenape) which was influential in the colonial period of the United States and is today headquartered in Cheswold, Kent County, Delaware. A band of the Nanticoke tribe of American Indians today resides in Sussex County and is headquartered in Millsboro, Sussex County, Delaware. Birth data Note: Births in table do not add up because Hispanics are counted both by their ethnicity and by their race, giving a higher overall number. Since 2016, data for births of White Hispanic origin are not collected, but included in one Hispanic group; persons of Hispanic origin may be of any race. Languages As of 2000, 91% of Delaware residents of age5 and older spoke only English at home; 5% spoke Spanish. French was the third-most spoken language at 0.7%, followed by Chinese at 0.5% and German at 0.5%. Legislation had been proposed in both the House and the Senate in Delaware to designate English as the official language. Neither bill was passed in the legislature. Sexual orientation A 2012 Gallup poll found that Delaware's proportion of lesbian, gay, bisexual, and transgender adults stood at 3.4 percent of the population. This constitutes a total LGBT adult population estimate of 23,698 people. The number of same-sex couple households in 2010 stood at 2,646. This grew by 41.65% from a decade earlier. On July 1, 2013, same-sex marriage was legalized, and all civil unions would be converted into marriages. Religion , Delaware is mostly Christian. Although Protestants account for almost half of the population, the Catholic Church is the largest single denomination in the state. The Association of Religion Data Archives reported in 2010 that the three largest denominational groups in Delaware by number of adherents are the Catholic Church at 182,532 adherents, the United Methodist Church with 53,656 members reported, and non-denominational Evangelical Protestant with 22,973 adherents reported. The religious body with the largest number of congregations is the United Methodist Church (with 158 congregations) followed by non-denominational Evangelical Protestant (with 106 congregations), then the Catholic Church (with 45 congregations). The Roman Catholic Diocese of Wilmington and the Episcopal Diocese of Delaware oversee the parishes within their denominations. The A.U.M.P. Church, the oldest African-American denomination in the nation, was founded in Wilmington. It still has a substantial presence in the state. Reflecting new immigrant populations, an Islamic mosque has been built in the Ogletown area, and a Hindu temple in Hockessin. Delaware is home to an Amish community which resides west of Dover in Kent County, consisting of nine church districts and about 1,650 people. The Amish first settled in Kent County in 1915. In recent years, increasing development has led to the decline in the number of Amish living in the community. A 2012 survey of religious attitudes in the United States found that 34% of Delaware residents considered themselves "moderately religious", 33% "very religious", and 33% as "non-religious". At the 2014 Pew Research survey, 23% of the population were irreligious. Economy Affluence According to a 2020 study by Kiplinger, Delaware had the seventeenth largest number of millionaires per capita in the United States, with a ratio of 6.98 percent, 0.7 percent from 2013 in ration but falling eight places in ranking. Delaware had 25,937 millionaires as of 2020. The median income for all Delaware households as of 2020 was $64,805. Agriculture Delaware's agricultural output consists of poultry, nursery stock, soybeans, dairy products and corn. Industries , the state's unemployment rate was 3.7%. The state's largest employers are: government (State of Delaware, New Castle County) education (University of Delaware, Delaware Technical Community College) banking (Bank of America, M&T Bank, JPMorgan Chase, Citigroup, Deutsche Bank) chemical, pharmaceutical, technology (DuPont de Nemours Inc., AstraZeneca, Syngenta, Agilent Technologies) healthcare (Christiana Care Health System (Christiana Hospital), Bayhealth Medical Center, Alfred I. duPont Hospital for Children) farming, specifically chicken farming in Sussex County (Perdue Farms, Mountaire Farms, Allen Family Foods) retail (Walmart, Walgreens, Acme Markets) Industrial decline Since the mid-2000s, Delaware has seen the departure of the state's automotive manufacturing industry (General Motors Wilmington Assembly and Chrysler Newark Assembly), the corporate buyout of a major bank holding company (MBNA), the departure of the state's steel industry (Evraz Claymont Steel), the bankruptcy of a fiber mill (National Vulcanized Fibre), and the diminishing presence of AstraZeneca in Wilmington. In late 2015, DuPont announced that 1,700 employees, nearly a third of its footprint in Delaware, would be laid off in early 2016. The merger of E.I. du Pont de Nemours & Co. and Dow Chemical Company into DowDuPont took place on September 1, 2017. Incorporation in Delaware More than half of all U.S. publicly traded companies, and 63% of the Fortune 500, are incorporated in Delaware. The state's attractiveness as a corporate haven is largely because of its business-friendly corporation law. Franchise taxes on Delaware corporations supply about a fifth of the state's revenue. Although "USA (Delaware)" ranked as the world's most opaque jurisdiction on the Tax Justice Network's 2009 Financial Secrecy Index, the same group's 2011 Index ranks the U.S. fifth and does not specify Delaware. In Delaware, there are more than a million registered corporations, meaning there are more corporations than people. Food and drink Title 4, chapter 7 of the Delaware Code stipulates that alcoholic liquor be sold only in specifically licensed establishments, and only between 9:00a.m. and 1:00a.m. Until 2003, Delaware was among the several states enforcing blue laws and banned the sale of liquor on Sunday. Media Newspapers Two daily newspapers are based in Delaware, the Delaware State News, based in Dover and covering the two southern counties, and The News Journal covering Wilmington and northern Delaware. The state is also served by several weekly, monthly and online publications. Television No standalone television stations are based solely in Delaware. The northern part of the state is served by network stations in Philadelphia and the southern part by network stations in Salisbury, Maryland. Philadelphia's ABC affiliate, WPVI-TV, maintains a news bureau in downtown Wilmington. Salisbury's CBS affiliate, WBOC-TV, maintains bureaus in Dover and Milton. Three Philadelphia-market stations—PBS member WHYY-TV, Ion affiliate WPPX, and MeTV affiliate WDPN-TV—all have Wilmington as their city of license, but maintain transmitters at the market antenna farm in Roxborough and do not produce any Delaware-centric programming. Radio There are a numerous radio stations licensed in Delaware.

Tourism Delaware is home to First State National Historical Park, a National Park Service unit composed of historic sites across the state including the New Castle Court House, Green, and Sheriff's House, Dover Green, Beaver Valley, Fort Christina, Old Swedes' Church, John Dickinson Plantation, and the Ryves Holt House. Delaware has several museums, wildlife refuges, parks, houses, lighthouses, and other historic places. Rehoboth Beach, together with the towns of Lewes, Dewey Beach, Bethany Beach, South Bethany, and Fenwick Island, comprise Delaware's beach resorts. Rehoboth Beach often bills itself as "The Nation's Summer Capital" because it is a frequent summer vacation destination for Washington, D.C., residents as well as visitors from Maryland, Virginia, and in lesser numbers, Pennsylvania. Vacationers are drawn for many reasons, including the town's charm, artistic appeal, nightlife, and tax-free shopping. According to SeaGrant Delaware, the Delaware beaches generate $6.9billion annually and over $711million in tax revenue. Delaware is home to several festivals, fairs, and events. Some of the more notable festivals are the Riverfest held in Seaford, the World Championship Punkin Chunkin formerly held at various locations throughout the state since 1986, the Rehoboth Beach Chocolate Festival, the Bethany Beach Jazz Funeral to mark the end of summer, the Apple Scrapple Festival held in Bridgeville, the Clifford Brown Jazz Festival in Wilmington, the Rehoboth Beach Jazz Festival, the Sea Witch Halloween Festival and Parade in Rehoboth Beach, the Rehoboth Beach Independent Film Festival, the Nanticoke Indian Pow Wow in Oak Orchard, Firefly Music Festival, and the Return Day Parade held after every election in Georgetown. In 2015, tourism in Delaware generated $3.1billion, which makes up five percent of the state's GDP. Delaware saw 8.5million visitors in 2015, with the tourism industry employing 41,730 people, making it the 4th largest private employer in the state.

Delaware is also home to two large sporting venues. Dover Motor Speedway is a race track in Dover, and Frawley Stadium in Wilmington is the home of the Wilmington Blue Rocks, a Minor League Baseball team. Education In the early 1920s, Pierre S. du Pont served as president of the state board of education. At the time, state law prohibited money raised from white taxpayers from being used to support the state's schools for black children. Appalled by the condition of the black schools, du Pont donated four million dollars to construct 86 new school buildings. Delaware was the origin of Belton v. Gebhart (1952), one of the four cases which were combined into Brown v. Board of Education, the Supreme Court of the United States decision that led to the end of officially segregated public schools. Significantly, Belton was the only case in which the state court found for the plaintiffs, thereby ruling that segregation is unconstitutional. Unlike many states, Delaware's educational system is centralized in a state Superintendent of Education, with local school boards retaining control over taxation and some curriculum decisions. This centralized system, combined with the small size of the state, likely contributed to Delaware becoming the first state, after completion of a three-year, $30million program ending in 1999, to wire every K-12 classroom in the state to the Internet. , the Delaware Department of Education had authorized the founding of 25 charter schools in the state, one of them being all-girls. All teachers in the State's public school districts are unionized. , none of the State's charter schools are members of a teachers union. One of the State's teachers' unions is Delaware State Education Association (DSEA). Colleges and universities Delaware College of Art and Design Delaware State University Delaware Technical & Community College Drexel University at Wilmington Goldey-Beacom College University of Delaware—Ranked 63rd in the U.S. and in top 201–250 in the world (Times Higher Education World University Rankings 2018) Wesley College Widener University School of Law Wilmington University Transportation The transportation system in Delaware is under the governance and supervision of the Delaware Department of Transportation, also known as "DelDOT". Funding for DelDOT projects is drawn, in part, from the Delaware Transportation Trust Fund, established in 1987 to help stabilize transportation funding; the availability of the Trust led to a gradual separation of DelDOT operations from other Delaware state operations. DelDOT manages programs such as a Delaware Adopt-a-Highway program, major road route snow removal, traffic control infrastructure (signs and signals), toll road management, Delaware Division of Motor Vehicles, the Delaware Transit Corporation (branded as "DART First State", the state government public transportation organization), among others. In 2009, DelDOT maintained 13,507 lane-miles, totaling 89 percent of the state's public roadway system, the rest being under the supervision of individual municipalities. This far exceeds the national average (20 percent) for state department of transportation maintenance responsibility. Roads One major branch of the U.S. Interstate Highway System, Interstate95 (I-95), crosses Delaware southwest-to-northeast across New Castle County. Two Auxiliary Interstate Highway routes are also located in the state. Interstate 495 (I-495) is an eastern bypass of Wilmington. Interstate 295 (I-295) is a bypass of Philadelphia which begins south of Wilmington. In addition to Interstate highways, there are six U.S. highways that serve Delaware: U.S.9, U.S.13, U.S.40, U.S.113, U.S.202, and U.S.301. There are also several state highways that cross the state of Delaware; a few of them include DE1, DE9, and DE404. U.S.13 and DE1 are primary north–south highways connecting Wilmington and Pennsylvania with Maryland, with DE1 serving as the main route between Wilmington and the Delaware beaches. DE9 is a north–south highway connecting Dover and Wilmington via a scenic route along the Delaware Bay. U.S.40 is a primary east–west route, connecting Maryland with New Jersey. DE404 is another primary east–west highway connecting the Chesapeake Bay Bridge in Maryland with the Delaware beaches. The state also operates three toll highways, the Delaware Turnpike, which is I-95, between Maryland and New Castle; the Korean War Veterans Memorial Highway, which is DE1, between Wilmington and Dover; and the U.S. 301 toll road between the Maryland border and DE1 in New Castle County. A bicycle route, Delaware Bicycle Route 1, spans the north–south length of the state from the Maryland border in Fenwick Island to the Pennsylvania border north of Montchanin. It is the first of several signed bike routes planned in Delaware. Delaware has about 1,450 bridges, 95 percent of which are under the supervision of DelDOT. About 30 percent of all Delaware bridges were built before 1950, and about 60 percent of the number are included in the National Bridge Inventory. Some bridges not under DelDOT supervision includes the four bridges on the Chesapeake and Delaware Canal, which are under the jurisdiction of the U.S. Army Corps of Engineers, and the Delaware Memorial Bridge, which is under the bi-state Delaware River and Bay Authority. It has been noted that the tar and chip composition of secondary roads in Sussex County makes them more prone to deterioration than are the asphalt roadways in almost the rest of the state. Among these roads, Sussex (county road) 236 is among the most problematic. Ferries Three ferries operate in the state of Delaware: Cape May–Lewes Ferry crosses the mouth of Delaware Bay between Lewes, Delaware, and Cape May, New Jersey. Woodland Ferry (a cable ferry) crosses the Nanticoke River southwest of Seaford. Forts Ferry Crossing connects Delaware City with Fort Delaware and Fort Mott, New Jersey. Rail and bus Amtrak has two stations in Delaware along the Northeast Corridor; the relatively quiet Newark Rail Station in Newark, and the busier Wilmington Rail Station in Wilmington. The Northeast Corridor is also served by SEPTA's Wilmington/Newark Line of Regional Rail, which serves Claymont, Wilmington, Churchmans Crossing, and Newark. Two Class I railroads, Norfolk Southern and CSX, provide freight rail service in northern New Castle County. Norfolk Southern provides freight service along the Northeast Corridor and to industrial areas in Edgemoor, New Castle, and Delaware City. CSX's Philadelphia Subdivision passes through northern New Castle County parallel to the Amtrak Northeast Corridor. Multiple short-line railroads provide freight service in Delaware. The Delmarva Central Railroad operates the most trackage of the short-line railroads, running from an interchange with Norfolk Southern in Porter south through Dover, Harrington, and Seaford to Delmar, with another line running from Harrington to Frankford and branches from Ellendale to Milton and from Georgetown to Gravel Hill. The Delmarva Central Railroad connects with the Maryland and Delaware Railroad, which serves local customers in Sussex County. CSX connects with the freight/heritage operation, the Wilmington and Western Railroad, based in Wilmington and the East Penn Railroad, which operates a line from Wilmington to Coatesville, Pennsylvania. The last north–south passenger trains through the main part of Delaware was the Pennsylvania Railroad's local Wilmington-Delmar train in 1965. This was a successor to the Del-Mar-Va Express and Cavalier, which had run from Philadelphia through the state's interior, to the end of the Delmarva Peninsula until the mid-1950s. The DART First State public transportation system was named "Most Outstanding Public Transportation System" in 2003 by the American Public Transportation Association. Coverage of the system is broad within northern New Castle County with close association to major highways in Kent and Sussex counties. The system includes bus, subsidized passenger rail operated by Philadelphia transit agency SEPTA, and subsidized taxi and paratransit modes. The paratransit system, consisting of a statewide door-to-door bus service for the elderly and disabled, has been described by a Delaware state report as "the most generous paratransit system in the United States". , fees for the paratransit service have not changed since 1988. Air , there is no scheduled air service from any Delaware airport, as has been the case in various years since 1991. Various airlines had served Wilmington Airport, the latest departure being Frontier Airlines in April 2015. Delaware is centrally situated in the Northeast megalopolis region of cities along I-95. Therefore, Delaware commercial airline passengers most frequently use Philadelphia International Airport (PHL), Baltimore-Washington International Thurgood Marshall Airport (BWI) and Washington Dulles International Airport (IAD) for domestic and international transit. Residents of Sussex County will also use Wicomico Regional Airport (SBY), as it is located less than from the Delaware border. Atlantic City International Airport (ACY), Newark Liberty International Airport (EWR), and Ronald Reagan Washington National Airport (DCA) are also within a radius of New Castle County. Other general aviation airports in Delaware include Summit Airport near Middletown, Delaware Airpark near Cheswold, and Delaware Coastal Airport near Georgetown. Dover Air Force Base, one of the largest in the country, is home to the 436th Airlift Wing and the 512th Airlift Wing. In addition to its other responsibilities in the Air Mobility Command, it serves as the entry point and mortuary for U.S. military personnel (and some civilians) who die overseas. Law and government Delaware's fourth and current constitution, adopted in 1897, provides for executive, judicial and legislative branches. Legislative branch The Delaware General Assembly consists of a House of Representatives with 41 members and a Senate with 21 members. It sits in Dover, the state capital. Representatives are elected to two-year terms, while senators are elected to four-year terms. The Senate confirms judicial and other nominees appointed by the governor. Delaware's U.S. Senators are Tom Carper (Democrat) and Chris Coons (Democrat). Delaware's single U.S. Representative is Lisa Blunt Rochester (Democrat). Judicial branch The Delaware Constitution establishes a number of courts: The Delaware Supreme Court is the state's highest court. The Delaware Superior Court is the state's trial court of general jurisdiction. The Delaware Court of Chancery deals primarily in corporate disputes. The Family Court handles domestic and custody matters. The Delaware Court of Common Pleas has jurisdiction over a limited class of civil and criminal matters. Minor non-constitutional courts include the Justice of the Peace Courts and Aldermen's Courts. Significantly, Delaware has one of the few remaining Courts of Chancery in the nation, which has jurisdiction over equity cases, the vast majority of which are corporate disputes, many relating to mergers and acquisitions. The Court of Chancery and the Delaware Supreme Court have developed a worldwide reputation for rendering concise opinions concerning corporate law which generally (but not always) grant broad discretion to corporate boards of directors and officers. In addition, the Delaware General Corporation Law, which forms the basis of the Courts' opinions, is widely regarded as giving great flexibility to corporations to manage their affairs. For these reasons, Delaware is considered to have the most business-friendly legal system in the United States; therefore a great number of companies are incorporated in Delaware, including 60% of the companies listed on the New York Stock Exchange. Delaware was the last U.S. state to use judicial corporal punishment, in 1952. Executive branch The executive branch is headed by the Governor of Delaware. The present governor is John Carney (Democrat), who took office January 17, 2017. The lieutenant governor is Bethany Hall-Long. The governor presents a "State of the State" speech to a joint session of the Delaware legislature annually. Counties Delaware is subdivided into three counties; from north to south they are New Castle, Kent and Sussex. This is the fewest among all states. Each county elects its own legislative body (known in New Castle and Sussex counties as County Council, and in Kent County as Levy Court), which deal primarily in zoning and development issues. Most functions which are handled on a county-by-county basis in other states—such as court and law enforcement—have been centralized in Delaware, leading to a significant concentration of power in the Delaware state government. The counties were historically divided into hundreds, which were used as tax reporting and voting districts until the 1960s, but now serve no administrative role, their only current official legal use being in real estate title descriptions. Politics The Democratic Party holds a plurality of registrations in Delaware. Currently, Democrats hold all positions of authority in Delaware, as well as majorities in the state Senate and House. The Democrats have held the governorship since 1993, having won the last seven gubernatorial elections. Democrats presently hold all the nine statewide elected offices, while the Republicans last won any statewide offices in 2014, State Auditor and State Treasurer. During the First and Second Party Systems, Delaware was a stronghold for the Federalist and Whig Parties, respectively. After a relatively brief adherence to the Democratic Solid South following the US Civil War, Delaware became a Republican-leaning state from 1896 through 1948, voting for losing Republicans Charles Evans Hughes in 1916, Herbert Hoover in 1932, and Thomas Dewey in 1948. During the second half of the 20th century, Delaware was a bellwether state, voting for the winner of every presidential election from 1952 through 1996. Delaware's bellwether status came to an end when Delaware voted for Al Gore in 2000 by 13%. Subsequent elections have continued to demonstrate Delaware's current strong Democratic lean: John Kerry carried the First State by 8% in 2004; Barack Obama carried it by 25% and by 19% in his two elections of 2008 and 2012; and Hillary Clinton carried it by 11% as she lost the Electoral College in 2016. In 2020, Delaware native (and Barack Obama's former Vice President and running mate) Joe Biden headed the Democratic ticket; he carried his home state by just shy of 19% en route to a national 4.5% win. The dominant factor in Delaware's political shift has been the strong Democratic trend in heavily urbanized New Castle County, home to 55% of Delaware's population. New Castle County has not voted Republican in a presidential election since 1988, and has given Democrats over 60% of its vote in every election from 2004 on. In 1992, 2000, 2004, and 2016, the Republican presidential candidate carried both Kent and Sussex but lost by double digits each time in New Castle County, which was a large enough margin to tip the state to the Democrats. New Castle County also elects a substantial majority of the state legislature; 27 of the 41 state house districts and 14 of the 21 state senate districts are based in New Castle County. In a 2020 study, Delaware was ranked as the 18th hardest state for citizens to vote in. Freedom of information Each of the 50 states of the United States has passed some form of freedom of information legislation, which provides a mechanism for the general public to request information of the government. In 2011 Delaware passed legislation placing a 15 business day time limit on addressing freedom-of-information requests, to either produce information or an explanation of why such information would take longer than this time to produce. Taxation Tax is collected by the Delaware Division of Revenue. Delaware has six different income tax brackets, ranging from 2.2% to 5.95%. The state does not assess sales tax on consumers. The state does, however, impose a tax on the gross receipts of most businesses. Business and occupational license tax rates range from 0.096% to 1.92%, depending on the category of business activity. Delaware does not assess a state-level tax on real or personal property. Real estate is subject to county property taxes, school district property taxes, vocational school district taxes, and, if located within an incorporated area, municipal property taxes. Gambling provides significant revenue to the state. For instance, the casino at Delaware Park Racetrack provided more than $100million to the state in 2010. In June 2018, Delaware became the first U.S. state to legalize sports betting following the Supreme Court ruling to repeal the Professional and Amateur Sports Protection Act of |
their translation in the Middle Persian language and phonetic transcription in the Pazend alphabet. A 9th-century CE Irish dictionary, Sanas Cormaic, contained etymologies and explanations of over 1,400 Irish words. In the 12th century, The Karakhanid - Turkic scholar Mahmud Kashgari finished his work "Divan-u Lügat'it Türk", a dictionary about the Turkic dialects, but especially Karakhanid Turkic. His work contains about 7500 to 8000 words and it was written to teach non Turkic Muslims, especially the Abbasid Arabs, the Turkic language. Al-Zamakhshari wrote a small Arabic dictionary called "Muḳaddimetü’l-edeb" for the Turkic-Khwarazm ruler Atsiz. In the 14th century, the Codex Cumanicus was finished and it served as a dictionary about the Cuman - Turkic language. While in Mamluk Egypt, Ebû Hayyân el-Endelüsî finished his work "Kitâbü’l-İdrâk li-lisâni’l-Etrâk", a dictionary about the Kipchak and Turcoman languages spoken in Egypt and the Levant. A dictionary called "Bahşayiş Lügati", which is written in old Anatolian Turkish, served also as a dictionary between Oghuz Turkish, Arabic and Persian. But it is not clear who wrote the dictionary or in which century exactly it was published. It was written in old Anatolian Turkish from the Seljuk period and not the late medieval Ottoman period.In India around 1320, Amir Khusro compiled the Khaliq-e-bari, which mainly dealt with Hindustani and Persian words. Arabic dictionaries were compiled between the 8th and 14th centuries CE, organizing words in rhyme order (by the last syllable), by alphabetical order of the radicals, or according to the alphabetical order of the first letter (the system used in modern European language dictionaries). The modern system was mainly used in specialist dictionaries, such as those of terms from the Qur'an and hadith, while most general use dictionaries, such as the Lisan al-`Arab (13th century, still the best-known large-scale dictionary of Arabic) and al-Qamus al-Muhit (14th century) listed words in the alphabetical order of the radicals. The Qamus al-Muhit is the first handy dictionary in Arabic, which includes only words and their definitions, eliminating the supporting examples used in such dictionaries as the Lisan and the Oxford English Dictionary. In medieval Europe, glossaries with equivalents for Latin words in vernacular or simpler Latin were in use (e.g. the Leiden Glossary). The Catholicon (1287) by Johannes Balbus, a large grammatical work with an alphabetical lexicon, was widely adopted. It served as the basis for several bilingual dictionaries and was one of the earliest books (in 1460) to be printed. In 1502 Ambrogio Calepino's Dictionarium was published, originally a monolingual Latin dictionary, which over the course of the 16th century was enlarged to become a multilingual glossary. In 1532 Robert Estienne published the Thesaurus linguae latinae and in 1572 his son Henri Estienne published the Thesaurus linguae graecae, which served up to the 19th century as the basis of Greek lexicography. The first monolingual dictionary written in Europe was the Spanish, written by Sebastián Covarrubias' Tesoro de la lengua castellana o española, published in 1611 in Madrid, Spain. In 1612 the first edition of the Vocabolario degli Accademici della Crusca, for Italian, was published. It served as the model for similar works in French and English. In 1690 in Rotterdam was published, posthumously, the Dictionnaire Universel by Antoine Furetière for French. In 1694 appeared the first edition of the Dictionnaire de l'Académie française (still published, with the ninth edition not complete ). Between 1712 and 1721 was published the Vocabulario portughez e latino written by Raphael Bluteau. The Real Academia Española published the first edition of the Diccionario de la lengua española (still published, with a new edition about every decade) in 1780; their Diccionario de Autoridades, which included quotes taken from literary works, was published in 1726. The Totius Latinitatis lexicon by Egidio Forcellini was firstly published in 1777; it has formed the basis of all similar works that have since been published. The first edition of A Greek-English Lexicon by Henry George Liddell and Robert Scott appeared in 1843; this work remained the basic dictionary of Greek until the end of the 20th century. And in 1858 was published the first volume of the Deutsches Wörterbuch by the Brothers Grimm; the work was completed in 1961. Between 1861 and 1874 was published the Dizionario della lingua italiana by Niccolò Tommaseo. Between 1862 and 1874 was published the six volumes of A magyar nyelv szótára (Dictionary of Hungarian Language) by Gergely Czuczor and János Fogarasi. Émile Littré published the Dictionnaire de la langue française between 1863 and 1872. In the same year 1863 appeared the first volume of the Woordenboek der Nederlandsche Taal which was completed in 1998. Also in 1863 Vladimir Ivanovich Dahl published the Explanatory Dictionary of the Living Great Russian Language. The Duden dictionary dates back to 1880, and is currently the prescriptive source for the spelling of German. The decision to start work on the Svenska Akademiens ordbok was taken in 1787. English dictionaries in Britain The earliest dictionaries in the English language were glossaries of French, Spanish or Latin words along with their definitions in English. The word "dictionary" was invented by an Englishman called John of Garland in 1220 — he had written a book Dictionarius to help with Latin "diction". An early non-alphabetical list of 8000 English words was the Elementarie, created by Richard Mulcaster in 1582. The first purely English alphabetical dictionary was A Table Alphabeticall, written by English schoolteacher Robert Cawdrey in 1604. The only surviving copy is found at the Bodleian Library in Oxford. This dictionary, and the many imitators which followed it, was seen as unreliable and nowhere near definitive. Philip Stanhope, 4th Earl of Chesterfield was still lamenting in 1754, 150 years after Cawdrey's publication, that it is "a sort of disgrace to our nation, that hitherto we have had no… standard of our language; our dictionaries at present being more properly what our neighbors the Dutch and the Germans call theirs, word-books, than dictionaries in the superior sense of that title." In 1616, John Bullokar described the history of the dictionary with his "English Expositor". Glossographia by Thomas Blount, published in 1656, contains more than 10,000 words along with their etymologies or histories. Edward Phillips wrote another dictionary in 1658, entitled "The New World of English Words: Or a General Dictionary" which boldly plagiarized Blount's work, and the two criticised each other. This created more interest in the dictionaries. John Wilkins' 1668 essay on philosophical language contains a list of 11,500 words with careful distinctions, compiled by William Lloyd. Elisha Coles published his "English Dictionary" in 1676. It was not until Samuel Johnson's A Dictionary of the English Language (1755) that a more reliable English dictionary was produced. Many people today mistakenly believe that Johnson wrote the first English dictionary: a testimony to this legacy. By this stage, dictionaries had evolved to contain textual references for most words, and were arranged alphabetically, rather than by topic (a previously popular form of arrangement, which meant all animals would be grouped together, etc.). Johnson's masterwork could be judged as the first to bring all these elements together, creating the first "modern" dictionary. Johnson's dictionary remained the English-language standard for over 150 years, until the Oxford University Press began writing and releasing the Oxford English Dictionary in short fascicles from 1884 onwards. It took nearly 50 years to complete this huge work, and they finally released the complete OED in twelve volumes in 1928. It remains the most comprehensive and trusted English language dictionary to this day, with revisions and updates added by a dedicated team every three months. One of the main contributors to this modern dictionary was an ex-army surgeon, William Chester Minor, a convicted murderer who was confined to an asylum for the criminally insane. American English dictionaries In 1806, American Noah Webster published his first dictionary, A Compendious Dictionary of the English Language. In 1807 Webster began compiling an expanded and fully comprehensive dictionary, An American Dictionary of the English Language; it took twenty-seven years to complete. To evaluate the etymology of words, Webster learned twenty-six languages, including Old English (Anglo-Saxon), German, Greek, Latin, Italian, Spanish, French, Hebrew, Arabic, and Sanskrit. Webster completed his dictionary during his year abroad in 1825 in Paris, France, and at the University of Cambridge. His book contained seventy thousand words, of which twelve thousand had never appeared in a published dictionary before. As a spelling reformer, Webster believed that English spelling rules were unnecessarily complex, so his dictionary introduced spellings that became American English, replacing "colour" with "color", substituting "wagon" for "waggon", and printing "center" instead of "centre". He also added American words, like "skunk" and "squash," which did not appear in British dictionaries. At the age of seventy, Webster published his dictionary in 1828; it sold 2500 copies. In 1840, the second edition was published in two volumes. Webster's dictionary was acquired by G & C Merriam Co. in 1843, after his death, and has since been published in many revised editions. Merriam-Webster was acquired by Encyclopedia Britannica in 1964. Controversy over the lack of usage advice in the 1961 Webster's Third New International Dictionary spurred publication of the 1969 The American Heritage Dictionary of the English Language, the first dictionary to use corpus linguistics. Types In a general dictionary, each word may have multiple meanings. Some dictionaries include each separate meaning in the order of most common usage while others list definitions in historical order, with the oldest usage first. In many languages, words can appear in many different forms, but only the undeclined or unconjugated form appears as the headword in most dictionaries. Dictionaries are most commonly found in the form of a book, but some newer dictionaries, like StarDict and the New Oxford American Dictionary are dictionary software running on PDAs or computers. There are also many online dictionaries accessible via the Internet. Specialized dictionaries According to the Manual of Specialized Lexicographies, a specialized dictionary, also referred to as a technical dictionary, is a dictionary that focuses upon a specific subject field, as opposed to a dictionary that comprehensively contains words from the lexicon of a specific language or languages. Following the description in The Bilingual LSP Dictionary, lexicographers categorize specialized dictionaries into three types: A multi-field dictionary broadly covers | Blount's work, and the two criticised each other.

Following the description in The Bilingual LSP Dictionary, lexicographers categorize specialized dictionaries into three types: A multi-field dictionary broadly covers several subject fields (e.g. a business dictionary), a single-field dictionary narrowly covers one particular subject field (e.g. law), and a sub-field dictionary covers a more specialized field (e.g. constitutional law). For example, the 23-language Inter-Active Terminology for Europe is a multi-field dictionary, the American National Biography is a single-field, and the African American National Biography Project is a sub-field dictionary. In terms of the coverage distinction between "minimizing dictionaries" and "maximizing dictionaries", multi-field dictionaries tend to minimize coverage across subject fields (for instance, Oxford Dictionary of World Religions and Yadgar Dictionary of Computer and Internet Terms) whereas single-field and sub-field dictionaries tend to maximize coverage within a limited subject field (The Oxford Dictionary of English Etymology). Another variant is the glossary, an alphabetical list of defined terms in a specialized field, such as medicine (medical dictionary). Defining dictionaries The simplest dictionary, a defining dictionary, provides a core glossary of the simplest meanings of the simplest concepts. From these, other concepts can be explained and defined, in particular for those who are first learning a language. In English, the commercial defining dictionaries typically include only one or two meanings of under 2000 words. With these, the rest of English, and even the 4000 most common English idioms and metaphors, can be defined. Prescriptive vs. descriptive Lexicographers apply two basic philosophies to the defining of words: prescriptive or descriptive. Noah Webster, intent on forging a distinct identity for the American language, altered spellings and accentuated differences in meaning and pronunciation of some words. This is why American English now uses the spelling color while the rest of the English-speaking world prefers colour. (Similarly, British English subsequently underwent a few spelling changes that did not affect American English; see further at American and British English spelling differences.) Large 20th-century dictionaries such as the Oxford English Dictionary (OED) and Webster's Third are descriptive, and attempt to describe the actual use of words. Most dictionaries of English now apply the descriptive method |
Friedman (born February 12, 1945) is an American economist, physicist, legal scholar, and anarcho-capitalist theorist, described by Walter E. Block as a "free-market anarchist". Although he studied chemistry and physics and not law or economics, he is known for his textbook writings on microeconomics and the libertarian theory of anarcho-capitalism, which is the subject of his most popular book, The Machinery of Freedom. He has also authored several other books and articles, including Price Theory: An Intermediate Text (1986), Law's Order: What Economics Has to Do with Law and Why It Matters (2000), Hidden Order: The Economics of Everyday Life (1996), and Future Imperfect (2008). Life and work David Friedman is the son of economists Rose and Milton Friedman. He graduated magna cum laude from Harvard University in 1965, with a bachelor's degree in chemistry and physics. He later earned a master's (1967) and a Ph.D. (1971) in theoretical physics from the University of Chicago. Despite his later career, he never took a class for credit in either economics or law. He was a professor of law at Santa Clara University from 2005 to 2017, and a contributing editor for Liberty magazine. He is currently a Professor Emeritus. He is an atheist. His son, Patri Friedman, has also written about libertarian theory and market anarchism, particularly seasteading. The Machinery of Freedom In his book The Machinery of Freedom (1973), Friedman sketched a form of anarcho-capitalism where all goods and services including law itself can be produced by the free market.

Friedman advocates an incrementalist approach to achieve anarcho-capitalism by gradual privatization of areas that government is involved in, ultimately privatizing the law itself. In the book, he states his opposition to violent anarcho-capitalist revolution. He advocates a consequentialist version of anarcho-capitalism, arguing for it on a cost-benefit analysis of state versus no state. It is contrasted with the natural-rights approach as propounded most notably by economist and libertarian theorist Murray Rothbard. Non-academic interests Friedman is a longtime member of the Society for Creative Anachronism, where he is known as Duke Cariadoc of the Bow. He is known throughout the worldwide society for his articles on the philosophy of recreationism and practical historical recreations, especially those relating to the medieval Middle East. His work is compiled in the popular Cariadoc's Miscellany. He is sometimes credited with founding the largest and longest-running SCA event, the Pennsic War; as king of the Middle Kingdom he challenged the East Kingdom, and later as king of the |
law that were not explained until later in terms of dissociating molecules. At the 1860 Karlsruhe Congress on atomic weights, Cannizzaro resurrected Avogadro's ideas and used them to produce a consistent table of atomic weights, which mostly agree with modern values. These weights were an important prerequisite for the discovery of the periodic law by Dmitri Mendeleev and Lothar Meyer. Excited electronic states Diatomic molecules are normally in their lowest or ground state, which conventionally is also known as the state. When a gas of diatomic molecules is bombarded by energetic electrons, some of the molecules may be excited to higher electronic states, as occurs, for example, in the natural aurora; high-altitude nuclear explosions; and rocket-borne electron gun experiments. Such excitation can also occur when the gas absorbs light or other electromagnetic radiation. The excited states are unstable and naturally relax back to the ground state. Over various short time scales after the excitation (typically a fraction of a second, or sometimes longer than a second if the excited state is metastable), transitions occur from higher to lower electronic states and ultimately to the ground state, and in each transition results a photon is emitted. This emission is known as fluorescence. Successively higher electronic states are conventionally named , , , etc. (but this convention is not always followed, and sometimes lower case letters and alphabetically out-of-sequence letters are used, as in the example given below). The excitation energy must be greater than or equal to the energy of the electronic state in order for the excitation to occur. In quantum theory, an electronic state of a diatomic molecule is represented by the molecular term symbol where is the total electronic spin quantum number, is the total electronic angular momentum quantum number along the internuclear axis, and is the vibrational quantum number. takes on values 0, 1, 2, ..., which are represented by the electronic state symbols , , ,.... For example, the following table lists the common electronic states (without vibrational quantum numbers) along with the energy of the lowest vibrational level () of diatomic nitrogen (N2), the most abundant gas in the Earth's atmosphere. In the table, the subscripts and superscripts after give additional quantum mechanical details about the electronic state. The aforementioned fluorescence occurs in distinct regions of the electromagnetic spectrum, called "emission bands": each band corresponds to a particular transition from a higher electronic state and vibrational level to a lower electronic state and vibrational level (typically, many vibrational levels are involved in an excited gas of diatomic molecules). For example, N2 - emission bands (a.k.a. Vegard-Kaplan bands) are present in the spectral range from 0.14 to 1.45 μm (micrometres).

In quantum theory, an electronic state of a diatomic molecule is represented by the molecular term symbol where is the total electronic spin quantum number, is the total electronic angular momentum quantum number along the internuclear axis, and is the vibrational quantum number. takes on values 0, 1, 2, ..., which are represented by the electronic state symbols , , ,.... For example, the following table lists the common electronic states (without vibrational quantum numbers) along with the energy of the lowest vibrational level () of diatomic nitrogen (N2), the most abundant gas in the Earth's atmosphere. In the table, the subscripts and superscripts after give additional quantum mechanical details about the electronic state. The aforementioned fluorescence occurs in distinct regions of the electromagnetic spectrum, called "emission bands": each band corresponds to a particular transition from a higher electronic state and vibrational level to a lower electronic state and vibrational level (typically, many vibrational levels are involved in an excited gas of diatomic molecules). For example, N2 - emission bands (a.k.a. Vegard-Kaplan bands) are present in the spectral range from 0.14 to 1.45 μm (micrometres). A given band can be spread out over several nanometers in electromagnetic wavelength space, owing to the various transitions that occur in the molecule's rotational quantum number, . These are classified into distinct sub-band branches, depending on the change in . The branch corresponds to , the branch to , and the branch to . Bands are spread out even further by the limited spectral resolution of the spectrometer that is used to measure the spectrum. The spectral resolution depends on the instrument's point spread function. Energy levels The molecular term symbol is a shorthand expression of the angular momenta that characterize the electronic quantum states of a diatomic molecule, which are also eigenstates of the electronic molecular Hamiltonian. It is also convenient, and common, to represent a diatomic molecule as two-point masses connected by a massless spring. The energies involved in the |

as campaign settings. Miniature figures The wargames from which Dungeons & Dragons evolved used miniature figures to represent combatants. D&D initially continued the use of miniatures in a fashion similar to its direct precursors. The original D&D set of 1974 required the use of the Chainmail miniatures game for combat resolution. By the publication of the 1977 game editions, combat was mostly resolved verbally. Thus miniatures were no longer required for game play, although some players continued to use them as a visual reference. In the 1970s, numerous companies began to sell miniature figures specifically for Dungeons & Dragons and similar games. Licensed miniature manufacturers who produced official figures include Grenadier Miniatures (1980–1983), Citadel Miniatures (1984–1986), Ral Partha, and TSR itself. Most of these miniatures used the 25 mm scale. Periodically, Dungeons & Dragons has returned to its wargaming roots with supplementary rules systems for miniatures-based wargaming. Supplements such as Battlesystem (1985 and 1989) and a new edition of Chainmail (2001) provided rule systems to handle battles between armies by using miniatures. Development history Sources and influences An immediate predecessor of Dungeons & Dragons was a set of medieval miniature rules written by Jeff Perren. These were expanded by Gary Gygax, whose additions included a fantasy supplement, before the game was published as Chainmail. When Dave Wesely entered the Army in 1970, his friend and fellow Napoleonics wargamer Dave Arneson began a medieval variation of Wesely's Braunstein games, where players control individuals instead of armies. Arneson used Chainmail to resolve combat. As play progressed, Arneson added such innovations as character classes, experience points, level advancement, armor class, and others. Having partnered previously with Gygax on Don't Give Up the Ship!, Arneson introduced Gygax to his Blackmoor game and the two then collaborated on developing "The Fantasy Game", the game that became Dungeons & Dragons, with the final writing and preparation of the text being done by Gygax. The name was chosen by Gygax's two-year-old daughter Cindy; upon being presented with a number of choices of possible names, she exclaimed, "Oh Daddy, I like Dungeons & Dragons best!", although less prevalent versions of the story gave credit to his then wife Mary Jo. Many Dungeons & Dragons elements appear in hobbies of the mid-to-late 20th century. For example, character-based role playing can be seen in improvisational theater. Game-world simulations were well developed in wargaming. Fantasy milieux specifically designed for gaming could be seen in Glorantha's board games among others. Ultimately, however, Dungeons & Dragons represents a unique blending of these elements. The world of D&D was influenced by world mythology, history, pulp fiction, and contemporary fantasy novels. The importance of J. R. R. Tolkien's The Lord of the Rings and The Hobbit as an influence on D&D is controversial. The presence in the game of halflings, elves, half-elves, dwarves, orcs, rangers, and the like, draw comparisons to these works. The resemblance was even closer before the threat of copyright action from Tolkien Enterprises prompted the name changes of hobbit to 'halfling', ent to 'treant', and balrog to 'balor'. For many years, Gygax played down the influence of Tolkien on the development of the game. However, in an interview in 2000, he acknowledged that Tolkien's work had a "strong impact" though he also said that the list of other influential authors was long. The D&D magic system, in which wizards memorize spells that are used up once cast and must be re-memorized the next day, was heavily influenced by the Dying Earth stories and novels of Jack Vance. The original alignment system (which grouped all characters and creatures into 'Law', 'Neutrality' and 'Chaos') was derived from the novel Three Hearts and Three Lions by Poul Anderson. A troll described in this work influenced the D&D definition of that monster. Other influences include the works of Robert E. Howard, Edgar Rice Burroughs, A. Merritt, H. P. Lovecraft, Fritz Leiber, L. Sprague de Camp, Fletcher Pratt, Roger Zelazny, and Michael Moorcock. Monsters, spells, and magic items used in the game have been inspired by hundreds of individual works such as A. E. van Vogt's "Black Destroyer", Coeurl (the Displacer Beast), Lewis Carroll's "Jabberwocky" (vorpal sword) and the Book of Genesis (the clerical spell 'Blade Barrier' was inspired by the "flaming sword which turned every way" at the gates of Eden). Edition history Dungeons & Dragons has gone through several revisions. Parallel versions and inconsistent naming practices can make it difficult to distinguish between the different editions. Original game The original Dungeons & Dragons, now referred to as OD&D, was a small box set of three booklets published in 1974. With a very limited production budget of only $2000 — with only $100 budgeted for artwork — it was amateurish in production and assumed the player was familiar with wargaming. Nevertheless, it grew rapidly in popularity, first among wargamers and then expanding to a more general audience of college and high school students. Roughly 1,000 copies of the game were sold in the first year followed by 3,000 in 1975, and many more in the following years. This first set went through many printings and was supplemented with several official additions, such as the original Greyhawk and Blackmoor supplements (both 1975), as well as magazine articles in TSR's official publications and many fanzines. Two-pronged strategy In early 1977, TSR created the first element of a two-pronged strategy that would divide D&D for nearly two decades. A Dungeons & Dragons Basic Set boxed edition was introduced that cleaned up the presentation of the essential rules, made the system understandable to the general public, and was sold in a package that could be stocked in toy stores. Later in 1977, the first part of Advanced Dungeons & Dragons (AD&D) was published, which brought together the various published rules, options and corrections, then expanded them into a definitive, unified game for hobbyist gamers. TSR marketed them as an introductory game for new players and a more complex game for experienced ones; the Basic Set directed players who exhausted the possibilities of that game to switch to the advanced rules. As a result of this parallel development, the basic game included many rules and concepts which contradicted comparable ones in AD&D. John Eric Holmes, the editor of the basic game, preferred a lighter tone with more room for personal improvisation. AD&D, on the other hand, was designed to create a tighter, more structured game system than the loose framework of the original game. Between 1977 and 1979, three hardcover rulebooks, commonly referred to as the "core rulebooks", were released: the Player's Handbook (PHB), the Dungeon Master's Guide (DMG), and the Monster Manual (MM). Several supplementary books were published throughout the 1980s, notably Unearthed Arcana (1985) that included a large number of new rules. Confusing matters further, the original D&D boxed set remained in publication until 1979, since it remained a healthy seller for TSR. Revised editions In the 1980s, the rules for Advanced Dungeons & Dragons and "basic" Dungeons & Dragons remained separate, each developing along different paths. In 1981, the basic version of Dungeons & Dragons was revised by Tom Moldvay to make it even more novice-friendly. It was promoted as a continuation of the original D&D tone, whereas AD&D was promoted as advancement of the mechanics. An accompanying Expert Set, originally written by David "Zeb" Cook, allowed players to continue using the simpler ruleset beyond the early levels of play. In 1983, revisions of those sets by Frank Mentzer were released, revising the presentation of the rules to a more tutorial format. These were followed by Companion (1983), Master (1985), and Immortals (1986) sets. Each set covered game play for more powerful characters than the previous. The first four sets were compiled in 1991 as a single hardcover book, the Dungeons & Dragons Rules Cyclopedia, which was released alongside a new introductory boxed set. Advanced Dungeons & Dragons 2nd Edition was published in 1989, again as three core rulebooks; the primary designer was David "Zeb" Cook. The Monster Manual was replaced by the Monstrous Compendium, a loose-leaf binder that was subsequently replaced by the hardcover Monstrous Manual in 1993. In 1995, the core rulebooks were slightly revised, although still referred to by TSR as the 2nd Edition, and a series of Player's Option manuals were released as optional rulebooks. The release of AD&D 2nd Edition deliberately excluded some aspects of the game that had attracted negative publicity. References to demons and devils, sexually suggestive artwork, and playable, evil-aligned character types – such as assassins and half-orcs – were removed. The edition moved away from a theme of 1960s and 1970s "sword and sorcery" fantasy fiction to a mixture of medieval history and mythology. The rules underwent minor changes, including the addition of non-weapon proficiencies – skill-like abilities that originally appeared in 1st Edition supplements. The game's magic spells were divided into schools and spheres. A major difference was the promotion of various game settings beyond that of traditional fantasy. This included blending fantasy with other genres, such as horror (Ravenloft), science fiction (Spelljammer), and apocalyptic (Dark Sun), as well as alternative historical and non-European mythological settings. Wizards of the Coast In 1997, a near-bankrupt TSR was purchased by Wizards of the Coast. Following three years of development, Dungeons & Dragons 3rd edition was released in 2000. The new release folded the Basic and Advanced lines back into a single unified game. It was the largest revision of the D&D rules to date, and served as the basis for a multi-genre role-playing system designed around 20-sided dice, called the d20 System. The 3rd Edition rules were designed to be internally consistent and less restrictive than previous editions of the game, allowing players more flexibility to create the characters they wanted to play. Skills and feats were introduced into the core rules to encourage further customization of characters. The new rules standardized the mechanics of action resolution and combat. In 2003, Dungeons & Dragons v.3.5 was released as a revision of the 3rd Edition rules. This release incorporated hundreds of rule changes, mostly minor, and expanded the core rulebooks. In early 2005, Wizards of the Coast's R&D team started to develop Dungeons & Dragons 4th Edition, prompted mainly by the feedback obtained from the D&D playing community and a desire to make the game faster, more intuitive, and with a better play experience than under the 3rd Edition. The new game was developed through a number of design phases spanning from May 2005 until its release. Dungeons & Dragons 4th Edition was announced at Gen Con in August 2007, and the initial three core books were released June 6, 2008. 4th Edition streamlined the game into a simplified form and introduced numerous rules changes. Many character abilities were restructured into "Powers". These altered the spell-using classes by adding abilities that could be used at will, per encounter, or per day. Likewise, non-magic-using classes were provided with parallel sets of options. Software tools, including player character and monster building programs, became a major part of the game. This edition added the D&D Encounters program; a weekly event held at local stores designed to draw players back to the game by giving "the busy gamer the chance to play D&D once a week as their schedules allow. In the past, D&D games could take months, even years, and players generally had to attend every session so that the story flow wasn't interrupted. With Encounters, players can come and go as they choose and new players can easily be integrated into the story continuity". On January 9, 2012, Wizards of the Coast announced that it was working on a 5th edition of the game. The company planned to take suggestions from players and let them playtest the rules. Public playtesting began on May 24, 2012. At Gen Con 2012 in August, Mike Mearls, lead developer for 5th Edition, said that Wizards of the Coast had received feedback from more than 75,000 playtesters, but that the entire development process would take two years, adding, "I can't emphasize this enough ... we're very serious about taking the time we need to get this right." The release of the 5th Edition, coinciding with D&Ds 40th anniversary, occurred in the second half of 2014. Since the release of 5th edition, there have been over twenty Dungeon & Dragons books published including new rulebooks, campaign guides and adventure modules. 2017 had "the most number of players in its history — 12 million to 15 million in North America alone". Mary Pilon, for Bloomberg, reported that sales of 5th edition Dungeon & Dragons "were up 41 percent in 2017 from the year before, and soared another 52 percent in 2018, the game’s biggest sales year yet. [...] In 2017, 9 million people watched others play D&D on Twitch, immersing themselves in the world of the game without ever having to pick up a die or cast a spell". In 2018, Wizards of the Coast organized a massive live-stream event, the Stream of Many Eyes, where ten live-streamed sessions of Dungeons & Dragons were performed on Twitch over three days. This event won the Content Marketing Institute's 2019 award for best "In-Person (Event) Content Marketing Strategy". Dungeons & Dragons continued to have a strong presence on Twitch throughout 2019; this included a growing number of celebrity players and dungeon masters, such as Joe Manganiello, Deborah Ann Woll and Stephen Colbert. Wizards of the Coast has created, produced and sponsored multiple web series featuring Dungeons & Dragons. These shows have typically aired on the official Dungeons & Dragons Twitch and YouTube channels. In 2020, Wizards of the Coast announced that Dungeons & Dragons had its 6th annual year of growth in 2019 with a "300 percent increase in sales of their introductory box sets, as well as a 65% increase on sales in Europe, a rate which has more than quadrupled since 2014". In terms of player demographics in 2019, 39% of identified as female and 61% identified as male. 40% of players are considered Gen Z (24 years old or younger), 34% of players are in the age range of 25–34 and 26% of players are aged 35+. In January 2021, the Los Angeles Times reported that according to Liz Schuh, head of publishing and licensing for Dungeons & Dragons, "revenue was up 35% in 2020 compared with 2019, the seventh consecutive year of growth," and in 2020, during the COVID-19 pandemic, "virtual play rose 86% [...] aided by online platforms such as Roll20 and Fantasy Grounds". Sarah Parvini, for the Los Angeles Times, wrote, "players and scholars attribute the game’s resurgent popularity not only to the longueurs of the pandemic, but also to its reemergence in pop culture — on the Netflix series Stranger Things, whose main characters play D&D in a basement; on the sitcom The Big Bang Theory; or via the host of celebrities who display their love for the game online". In September 2021, it was announced that a backwards compatible "evolution" of 5th edition would be released in 2024 to mark the 50th anniversary of the game. Licensing Early in the game's history, TSR took no action against small publishers' production of D&D compatible material, and even licensed Judges Guild to produce D&D materials for several years, such as City State of the Invincible Overlord. This attitude changed in the mid-1980s when TSR took legal action to try to prevent others from publishing compatible material. This angered many fans and led to resentment by the other gaming companies. Although TSR took legal action against several publishers in an attempt to restrict third-party usage, it never brought any court cases to completion, instead settling out of court in every instance. TSR itself ran afoul of intellectual property law in several cases. With the launch of Dungeons & Dragonss 3rd Edition, Wizards of the Coast made the d20 System available under the Open Game License (OGL) and d20 System trademark license. Under these licenses, authors were free to use the d20 System when writing games and game supplements. The OGL and d20 Trademark License made possible new games, some based on licensed products like Star Wars, and new versions of older games, such as Call of Cthulhu. With the release of the fourth edition, Wizards of the Coast introduced its Game System License, which represented a significant restriction compared to the very open policies embodied by the OGL. In part as a response to this, some publishers (such as Paizo Publishing with its Pathfinder Roleplaying Game) who previously produced materials in support of the D&D product line, decided to continue supporting the 3rd Edition rules, thereby competing directly with Wizards of the Coast. Others, such as Kenzer & Company, are returning to the practice of publishing unlicensed supplements and arguing that copyright law does not allow Wizards of the Coast to restrict third-party usage. During the 2000s, there has been a trend towards reviving and recreating older editions of D&D, known as the Old School Revival. This in turn inspired the creation of "retro-clones", games which more closely recreate the original rule sets, using material placed under the OGL along with non-copyrightable mechanical aspects of the older rules to create a new presentation of the games. Alongside the publication of the 5th Edition, Wizards of the Coast established a two-pronged licensing approach. The core of the 5th Edition rules have been made available under the OGL, while publishers and independent creators have also been given the opportunity to create licensed materials directly for Dungeons & Dragons and associated properties like the Forgotten Realms under a program called the DM's Guild. The DM's Guild does not function under the OGL, but uses a community agreement intended to foster liberal cooperation among content creators. Wizards of the Coast has started to release 5th Edition products that tie into other intellectual properties — such as Magic: The Gathering with the Guildmasters' Guide to Ravnica (2018) and Mythic Odysseys of Theros (2020) source books. Two 5th Edition starter box sets based on TV shows, Stranger Things and Rick and Morty, were released in 2019. Source books based on Dungeons & Dragons live play series have also been released: Acquisitions Incorporated (2019) and Explorer's Guide to Wildemount (2020). Reception Eric Goldberg reviewed Dungeons & Dragons in Ares Magazine #1 (March 1980), rating it a 6 out of 9, and commented that "Dungeons and Dragons is an impressive achievement based on the concept alone, and also must be credited with cementing the marriage between the fantasy genre and gaming." Eric Goldberg again reviewed Dungeons & Dragons in Ares Magazine #3 and commented that "D&D is the FRP game played most often in most places." The game had more than three million players around the world by 1981, and copies of the rules were selling at a rate of about 750,000 per year by 1984. Beginning with a French language edition in 1982, Dungeons & Dragons has been translated into many languages beyond the original English. By 1992, the game had been translated into 14 languages and sold over copies in 44 countries worldwide. By 2004, consumers had spent more than on Dungeons & Dragons products and the game had been played by more than 20 million people. As many as six million people played the game in 2007. Later editions would lead to inevitable comparisons between the game series. Griffin McElroy, for Polygon, wrote: "The game has shifted in the past four decades, bouncing between different rules sets, philosophies and methods of play. Role-playing, character customization and real-life improvisational storytelling has always been at the game's core, but how those ideas are interpreted by the game system has changed drastically edition-to-edition". Dieter Bohn, for The Verge, wrote: "Every few years there’s been a new version of D&D that tries to address the shortcomings of the previous version and also make itself more palatable to its age.

Reception Eric Goldberg reviewed Dungeons & Dragons in Ares Magazine #1 (March 1980), rating it a 6 out of 9, and commented that "Dungeons and Dragons is an impressive achievement based on the concept alone, and also must be credited with cementing the marriage between the fantasy genre and gaming." Eric Goldberg again reviewed Dungeons & Dragons in Ares Magazine #3 and commented that "D&D is the FRP game played most often in most places." The game had more than three million players around the world by 1981, and copies of the rules were selling at a rate of about 750,000 per year by 1984. Beginning with a French language edition in 1982, Dungeons & Dragons has been translated into many languages beyond the original English. By 1992, the game had been translated into 14 languages and sold over copies in 44 countries worldwide. By 2004, consumers had spent more than on Dungeons & Dragons products and the game had been played by more than 20 million people. As many as six million people played the game in 2007. Later editions would lead to inevitable comparisons between the game series. Griffin McElroy, for Polygon, wrote: "The game has shifted in the past four decades, bouncing between different rules sets, philosophies and methods of play. Role-playing, character customization and real-life improvisational storytelling has always been at the game's core, but how those ideas are interpreted by the game system has changed drastically edition-to-edition". Dieter Bohn, for The Verge, wrote: "Every few years there’s been a new version of D&D that tries to address the shortcomings of the previous version and also make itself more palatable to its age. [...] The third edition got a reputation (which it didn’t necessarily deserve) for being too complex and rules-focused. The fourth edition got a reputation (which it didn’t necessarily deserve) for being too focused on miniatures and grids, too mechanical. Meanwhile, the company that owns D&D had released a bunch of its old material for free as a service to fans, and some of that was built up into a competing game called Pathfinder. Pathfinder ultimately became more popular, by some metrics, than D&D itself". Bohn highlighted that the 5th Edition was "designed for one purpose: to bring D&D back to its roots and win back everybody who left during the edition wars". Henry Glasheen, for SLUG Magazine, highlighted that after jumping ship during the 4th Edition era he was drawn back to Dungeons & Dragons with 5th Edition and he considers it "the new gold standard for D20-based tabletop RPGs". Glasheen wrote "Fifth Edition is a compelling reason to get excited about D&D again" and "while some will welcome the simplicity, I fully expect that plenty of people will stick to whatever system suits them best. However, this edition is easily my favorite, ranking even higher than D&D 3.5, my first love in D&D". Curtis D. Carbonell, in the book Dread Trident: Tabletop Role-Playing Games and the Modern Fantastic, wrote: "Negative association with earlier niche 'nerd' culture have reversed. 5e has become inclusive in its reach of players, after years of focusing on a white, male demographic. [...] At its simplest, the game system now encourages different types of persons to form a party not just to combat evil [...] but to engage in any number of adventure scenarios". Acclaim The various editions of Dungeons & Dragons have won many Origins Awards, including All Time Best Roleplaying Rules of 1977, Best Roleplaying Rules of 1989, Best Roleplaying Game of 2000 and Best Role Playing Game and Best Role Playing Supplement of 2014 for the flagship editions of the game. Both Dungeons & Dragons and Advanced Dungeons & Dragons are Origins Hall of Fame Games inductees as they were deemed sufficiently distinct to merit separate inclusion on different occasions.Academy of Adventure Gaming Arts and Design; Hall of Fame The independent Games magazine placed Dungeons & Dragons on their Games 100 list from 1980 through 1983, then entered the game into the magazine's Hall of Fame in 1984.Games Magazine Online; Hall of Fame Advanced Dungeons & Dragons was ranked 2nd in the 1996 reader poll of Arcane magazine to determine the 50 most popular roleplaying games of all time. Dungeons & Dragons was inducted into the National Toy Hall of Fame in 2016 and into the Science Fiction and Fantasy Hall of Fame in 2017. Legacy and influence Dungeons & Dragons was the first modern role-playing game and it established many of the conventions that have dominated the genre. Particularly notable are the use of dice as a game mechanic, character record sheets, use of numerical attributes and gamemaster-centered group dynamics. Within months of Dungeons & Dragons'''s release, new role-playing game writers and publishers began releasing their own role-playing games, with most of these being in the fantasy genre. Some of the earliest other role-playing games inspired by D&D include Tunnels & Trolls (1975), Empire of the Petal Throne (1975), and Chivalry & Sorcery (1976). The role-playing movement initiated by D&D would lead to release of the science fiction game Traveller (1977), the fantasy game RuneQuest (1978), and subsequent game systems such as Chaosium's Call of Cthulhu (1981), Champions (1982), GURPS (1986), and Vampire: The Masquerade (1991).Darlington; A History of Role-Playing Part VIII Dungeons & Dragons and the games it influenced fed back into the genre's origin – miniatures wargames – with combat strategy games like Warhammer Fantasy Battles. D&D also had a large impact on modern video games.D&D has been compared unfavorably to other role-playing games of its time. Writing for Slate, Erik Sofge makes unfavorable comparisons between the violent incentives of D&D and the more versatile role-playing experience of GURPS. He claims that "for decades, gamers have argued that since D&D came first, its lame, morally repulsive experience system can be forgiven. But the damage is still being done: New generations of players are introduced to RPGs as little more than a collective fantasy of massacre." This criticism generated backlash from D&D fans. Writing for Ars Technica, Ben Kuchera responded that Sofge had experienced a "small-minded Dungeon Master who only wanted to kill things", and that better game experiences are possible. Director Jon Favreau credits Dungeons & Dragons with giving him "... a really strong background in imagination, storytelling, understanding how to create tone and a sense of balance." ND Stevenson and the crew of She-Ra and the Princesses of Power were strongly influenced by Dungeons & Dragons, with Stevenson calling it basically a D&D campaign, with Adora, Glimmer, and Bow falling into "specific classes in D&D". Controversy and notoriety The game's commercial success was a factor that led to lawsuits regarding distribution of royalties between original creators Gygax and Arneson.Rausch; Dave Arneson Interview Gygax later became embroiled in a political struggle for control of TSR which culminated in a court battle and Gygax's decision to sell his ownership interest in the company in 1985. At various times in its history, Dungeons & Dragons has received negative publicity, in particular from some Christian groups, for alleged promotion of such practices as devil worship, witchcraft, suicide, and murder, and for the presence of naked breasts in drawings of female humanoids in the original AD&D manuals (mainly monsters such as harpies, succubi, etc.). These controversies led TSR to remove many potentially controversial references and artwork when releasing the 2nd Edition of AD&D. Many of these references, including the use of the names "devils" and "demons", were reintroduced in the 3rd edition. The moral panic over the game led to problems for fans of D&D who faced social ostracism, unfair treatment, and false association with the occult and Satanism, regardless of an individual fan's actual religious affiliation and beliefs.Dungeons & Dragons has also been the subject of rumors regarding players having difficulty separating fantasy from reality, even leading to psychotic episodes. The most notable of these was the saga of James Dallas Egbert III, the facts of which were fictionalized in the novel Mazes and Monsters and later made into a TV movie in 1982 starring Tom Hanks. William Dear, the private investigator hired by the Egbert family to find their son when he went missing at college, wrote a book titled The Dungeon Master refuting any connection with D&D and Egbert's personal issues. The game was blamed for some of the actions of Chris Pritchard, who was convicted in 1990 of murdering his stepfather. Research by various psychologists, starting with Armando Simon, has concluded that no harmful effects are related to the playing of D&D.Dungeons & Dragons has, however, been cited as encouraging people to socialize weekly or biweekly, teaching problem solving skills which can be beneficial in adult life, and teaching positive moral decisions. In 2020, Polygon reported that "the D&D team announced that it would be making changes to portions of its 5th edition product line that fans have called out for being insensitive". Sebastian Modak, for The Washington Post, reported that the tabletop community has widely approved these changes. Modak wrote that "in its statement addressing mistakes around portrayals of different peoples in the D&D universe, Wizards of the Coast highlighted its recent efforts in bringing in more diverse voices to craft the new D&D source books coming out in 2021. [...] These conversations — around depictions of race and alleged treatment of employees of marginalized backgrounds and identities — have encouraged players to seek out other tabletop roleplaying experiences". Matthew Gault, for Wired, reported positively on the roundtable discussions Wizards of the Coast has hosted with fans and community leaders on diversity and inclusion. However, Gault also highlighted that other efforts, such as revisions to old material and the release of new material, have been less great and at times minimal. Gault wrote, "WotC appears to be trying to change things, but it keeps stumbling, and it’s often the fans who pick up the pieces. [...] WotC is trying to make changes, but it often feels like lip service. [...] The loudest voices criticizing D&D right now are doing it out of love. They don’t want to see it destroyed, they want it to change with the times". However, in 2022, academic Christopher Ferguson stated that the game "was not associated with greater ethnocentrism (one facet of racism) attitudes" after he conducted a survey study of 308 adults (38.2% non-White, and 17% Dungeons and Dragons players). Ferguson concluded that Wizards of the Coast may be responding to a moral panic similar to that surrounding Satanism in the 1990s. Related productsD&Ds commercial success has led to many other related products, including Dragon and Dungeon magazines, an animated television series, a film series, an official role-playing soundtrack, novels, both ongoing and limited series licensed comics, and numerous computer and video games. Hobby and toy stores sell dice, miniatures, adventures, and other game aids related to D&D and its game offspring. In popular cultureD&D grew in popularity through the late 1970s and 1980s. Numerous games, films, and cultural references based on D&D or D&D-like fantasies, characters or adventures have been ubiquitous since the end of the 1970s. D&D players are (sometimes pejoratively) portrayed as the epitome of geekdom, and have become the basis of much geek and gamer humor and satire. "In 2017, 9 million people watched others play D&D on Twitch, immersing themselves in the world of the game without ever having to pick up a die or cast a spell". Since the release of 5th edition, these D&D shows have only grown in popularity. Critical Role, one of the most popular D&D shows, brings in an average of 21,978 viewers per week.

convicted of second-degree murder in the second trial. France Once all appeals have been exhausted on a case, the judgement is final and the action of the prosecution is closed (code of penal procedure, art. 6), except if the final ruling was forged. Prosecution for a crime already judged is impossible even if incriminating evidence has been found. However, a person who has been convicted may request another trial on the grounds of new exculpating evidence through a procedure known as révision. Germany The Basic Law (Grundgesetz) for the Federal Republic of Germany protects against double jeopardy if a final verdict is pronounced. A verdict is final if nobody appeals against it. However, each trial party can appeal against a verdict in the first instance. The prosecution or the defendants can appeal against a judgement if they disagree with it. In this case, the trial starts again in the second instance, the court of appeal (Berufungsgericht), which reconsiders the facts and reasons and delivers a final judgement. If one of the parties disagrees with the second instance's judgement, they can appeal it only for formal judicial reasons. The case will be checked in the third instance (Revisionsgericht), whether all laws are applied correctly. The rule applies to the whole "historical event, which is usually considered a single historical course of actions the separation of which would seem unnatural". This is true even if new facts occur that indicate other crimes. The Penal Procedural Code (Strafprozessordnung) permits a retrial (Wiederaufnahmeverfahren), if it is in favour of the defendant or if the following events had happened: In the case of an order of summary punishment, which can be issued by the court without a trial for lesser misdemeanours, there is a further exception: In Germany, a felony is defined by § 12 (1) StGB as a crime that has a minimum of one year of imprisonment. India A partial protection against double jeopardy is a Fundamental Right guaranteed under Article 20 (2) of the Constitution of India, which states "No person shall be prosecuted and punished for the same offence more than once". This provision enshrines the concept of autrefois convict, that no one convicted of an offence can be tried or punished a second time. However, it does not extend to autrefois acquit, and so if a person is acquitted of a crime he can be retried. In India, protection against autrefois acquit is a statutory right, not a fundamental one. Such protection is provided by provisions of the Code of Criminal Procedure rather than by the Constitution. Japan The Constitution of Japan, which came into effect on May 3, 1947, states in Article 39 that However, in 1950, one defendant was found guilty in the District Court for crimes related to the election law and was sentenced to paying a fine. The prosecutor wanted a stronger sentence and appealed to the High Court. As a result, the defendant was sentenced to three months of imprisonment. He appealed to the Supreme Court on the grounds that the sentence was excessive when compared with precedents and that he had been placed in double jeopardy, which was in violation of Article 39. On September 27, 1950, all fifteen judges of the Supreme Court made the Grand Bench Decision to rule against the defendant and declared that a criminal proceeding in the District Court, High Court and Supreme Court is all one case and that there is no double jeopardy. In other words, if the prosecutor appeals against a judgement of not guilty or a guilty decision that they think does not impose a severe enough sentence, the defendant will not be placed in double jeopardy. On October 10, 2003, the Supreme Court made a landmark decision in the area of double jeopardy. The case involved Article 235 of the Penal Code, which addresses “simple larceny”, and Article 2 of the Law for Prevention and Disposition of Robbery, Theft, etc., which addresses “habitual larceny”. The Court ruled that in the event that there are two trials for separate cases of simple larceny, it will not be considered double jeopardy, even if the prosecutor could have charged both of them as a single crime of habitual larceny. The defendant in this case had committed crimes of trespassing and simple larceny on 22 separate occasions. The defence counsel argued that the crimes were actually one offence of habitual larceny and that charging them as separate counts was double jeopardy. The Supreme Court ruled that it was within the prosecutor’s discretion as to whether to charge the defendant with one count of habitual larceny or to charge them with multiple counts of trespassing and simple larceny. In either case, it is not considered double jeopardy. The Netherlands In the Netherlands, the state prosecution can appeal a not-guilty verdict at the bench. New evidence can be applied during a retrial at a district court. Thus one can be tried twice for the same alleged crime. If one is convicted at the district court, the defence can make an appeal on procedural grounds to the supreme court. The supreme court might admit this complaint, and the case will be reopened yet again, at another district court. Again, new evidence might be introduced by the prosecution. On 9 April 2013 the Dutch senate voted 36 "yes" versus 35 "no" in favour of a new law that allows the prosecutor to re-try a person who was found not guilty in court. This new law is limited to crimes where someone died and new evidence must have been gathered. The new law also works retroactively. Pakistan Article 13 of the Constitution of Pakistan protects a person from being punished or prosecuted more than once for the same offence. Section 403 of The Code of Criminal Procedure contemplates of a situation where as person having once been tried by a Court of competent jurisdiction and acquitted by such court cannot be tried again for the same offence or for any other offence based on similar facts. The scope of section 403 is restricted to criminal proceedings and not to civil proceedings and departmental inquiries. Serbia This principle is incorporated into the Constitution of the Republic of Serbia and further elaborated in its Criminal Procedure Act. South Africa The Bill of Rights in the Constitution of South Africa forbids a retrial when there has already been an acquittal or a conviction. South Korea Article 13 of the South Korean constitution provides that no citizen shall be placed in double jeopardy. United Kingdom England and Wales Double jeopardy has been permitted in England and Wales in certain (exceptional) circumstances since the Criminal Justice Act 2003. Pre-2003 The doctrines of autrefois acquit and autrefois convict persisted as part of the common law from the time of the Norman conquest of England; they were regarded as essential elements for protection of the subject's liberty and respect for due process of law in that there should be finality of proceedings. There were only three exceptions, all relatively recent, to the rules: The prosecution has a right of appeal against acquittal in summary cases if the decision appears to be wrong in law or in excess of jurisdiction. A retrial is permissible if the interests of justice so require, following appeal against conviction by a defendant. A "tainted acquittal", where there has been an offence of interference with, or intimidation of, a juror or witness, can be challenged in the High Court. In Connelly v DPP [1964] AC 1254, the Law Lords ruled that a defendant could not be tried for any offence arising out of substantially the same set of facts relied upon in a previous charge of which he had been acquitted, unless there are "special circumstances" proven by the prosecution. There is little case law on the meaning of "special circumstances", but it has been suggested that the emergence of new evidence would suffice.

There is little case law on the meaning of "special circumstances", but it has been suggested that the emergence of new evidence would suffice. A defendant who had been convicted of an offence could be given a second trial for an aggravated form of that offence if the facts constituting the aggravation were discovered after the first conviction. By contrast, a person who had been acquitted of a lesser offence could not be tried for an aggravated form even if new evidence became available. Post-2003 Following the murder of Stephen Lawrence, the Macpherson Report recommended that the double jeopardy rule should be abrogated in murder cases, and that it should be possible to subject an acquitted murder suspect to a second trial if "fresh and viable" new evidence later came to light. The Law Commission later added its support to this in its report "Double Jeopardy and Prosecution Appeals" (2001). A parallel report into the criminal justice system by Lord Justice Auld, a past Senior Presiding Judge for England and Wales, had also commenced in 1999 and was published as the Auld Report six months after the Law Commission report. It opined that the Law Commission had been unduly cautious by limiting the scope to murder and that "the exceptions should [...] extend to other grave offences punishable with life and/or long terms of imprisonment as Parliament might specify." Both Jack Straw (then Home Secretary) and William Hague (then Leader of the Opposition) favoured this measure. These recommendations were implemented—not uncontroversially at the time—within the Criminal Justice Act 2003, and this provision came into force in April 2005. It opened certain serious crimes (including murder, manslaughter, kidnapping, rape, armed robbery, and serious drug crimes) to a retrial, regardless of when committed, with two conditions: the retrial must be approved by the Director of Public Prosecutions, and the Court of Appeal must agree to quash the original acquittal due to "new and compelling evidence". Then Director of Public Prosecutions, Ken Macdonald QC, said that he expected no more than a handful of cases to be brought in a year. Pressure by Ann Ming, the mother of 1989 murder victim Julie Hogg—whose killer, Billy Dunlop, was initially acquitted and subsequently confessed—also contributed to the demand for legal change. On 11 September 2006, Dunlop became the first person to be convicted of murder following a prior acquittal for the same crime, in his case his 1991 acquittal of Hogg's murder. Some years later he had confessed to the crime, and was convicted of perjury, but was unable to be retried for the killing itself. The case was re-investigated in early 2005, when the new law came into effect, and his case was referred to the Court of Appeal, in November 2005, for permission for a new trial, which was granted. Dunlop pleaded guilty to murder and was sentenced to life imprisonment, with a recommendation he serve no less than 17 years. On 13 December 2010, Mark Weston became the first person to be retried and found guilty of murder by a jury (Dunlop having confessed). In 1996 Weston had been acquitted of the murder of Vikki Thompson at Ascott-under-Wychwood on 12 August 1995, but following the discovery in 2009 of compelling new evidence (Thompson's blood on Weston's boots) he was arrested and tried for a second time. He was sentenced to life imprisonment, to serve a minimum of 13 years. In December 2018, convicted paedophile Russell Bishop was also retried and found guilty by a jury for the Babes in the Wood murders of two 9-year-old girls, Nicola Fellows and Karen Hadaway, on 9 October 1986. At the original trial in 1987, a key piece of the prosecution's case rested on the recovery of a discarded blue sweatshirt. Under questioning, Bishop denied that the sweatshirt belonged to him, but his girlfriend, Jennifer Johnson, alleged the clothing was Bishop's, before she changed her story in the trial, telling the jury she had never seen the top before. Attributed to a series of blunders in the prosecution's case, Bishop was acquitted by the jury after two hours of deliberations. Three years later, Bishop was found guilty of the abduction, molestation, and attempted murder of a 7-year-old girl in February 1990. In 2014, re-examined by modern forensics, the sweatshirt contained traces of Bishop's DNA, and also had fibres on it from both of the girls' clothing. Tapings taken from Karen Hadaway's arm also yielded traces of Bishop's DNA. At the 2018 trial, a jury of seven men and five women returned a guilty verdict after two-and-a-half hours of deliberation. On 14 November 2019, Michael Weir became the first person to be twice found guilty of a murder. He was originally convicted of the murder of Leonard Harris and Rose Seferian in 1999, but the conviction was quashed in 2000 by the Court of Appeal on a technicality. In 2018, new DNA evidence had been obtained and palm prints from both murder scenes were matched to Weir. Twenty years after the original conviction, Weir was convicted of the murders for a second time. Scotland The double jeopardy rule no longer applies absolutely in Scotland since the Double Jeopardy (Scotland) Act 2011 came into force on 28 November 2011. The Act introduced three broad exceptions to the rule: where the acquittal had been tainted by an attempt to pervert the course of justice; where the accused admitted their guilt after acquittal; and where there was new evidence. Northern Ireland In Northern Ireland, the Criminal Justice Act 2003, effective 18 April 2005, makes certain "qualifying offence" (including murder, rape, kidnapping, specified sexual acts with young children, specified drug offences, defined acts of terrorism, as well as in certain cases attempts or conspiracies to commit the foregoing) subject to retrial after acquittal (including acquittals obtained before passage of the Act) if there is a finding by the Court of Appeal that there is "new and compelling evidence." United States The ancient protection of the Common Law against double jeopardy is maintained in its full rigour in the United States. The Fifth Amendment to the United States Constitution provides: Conversely, double jeopardy comes with a key exception. Under the multiple sovereignties doctrine, multiple sovereigns can indict a defendant for the same crime. The federal and state governments can have overlapping criminal laws, so a criminal offender may be convicted in individual states and federal courts for exactly the same crime or for different crimes arising out of the same facts. However, in 2016, the Supreme Court held that Puerto Rico is not a separate sovereign for purposes of the Double Jeopardy Clause. The dual sovereignty doctrine has been the subject of substantial scholarly criticism. As described by the U.S. Supreme Court in its unanimous decision concerning Ball v. United States 163 U.S. 662 (1896), one of its earliest cases dealing with double jeopardy, "the prohibition is not against being twice punished, but against being twice put in jeopardy; and the accused, whether convicted or acquitted, is equally put in jeopardy at the first trial." The Double Jeopardy Clause encompasses four distinct prohibitions: subsequent prosecution after acquittal, subsequent prosecution after conviction, subsequent prosecution after certain mistrials, and multiple punishment in the same indictment. Jeopardy "attaches" when the jury is impanelled, the first witness is sworn, or a plea is accepted. Prosecution after acquittal With two exceptions, the government is not permitted to appeal or retry the defendant once jeopardy attaches to a trial unless the case does not conclude. Conditions which constitute "conclusion" of a case include After the entry of an acquittal, whether: a directed verdict before the case is submitted to the jury, a directed verdict after a deadlocked jury, an appellate reversal for sufficiency (except by direct appeal to a higher appellate court), or an "implied acquittal" via conviction of a lesser included offence. re-litigating against the same defence a fact necessarily found by the jury in a prior acquittal, even if the jury hung on |
state law, despite many participating in a uniform scheme. Admission as a lawyer is the business of the admissions board and the Supreme Court. Disciplinary proceedings may be commenced by the Bar Association or the Law Society of which one is a member, or the board itself. Germany In Germany, a Berufsverbot is a ban on practicing a profession, which the government can issue to a lawyer for misconduct, Volksverhetzung or for serious mismanagement of personal finances. In April 1933, the Nazi government issued a Berufsverbot forbidding the practice of law by Jews, Communists, and other political opponents, except for those protected by the Frontkämpferprivileg. United Kingdom In the United Kingdom, the removal of the licence to practise of a barrister or Scottish advocate is called being "disbarred", whilst the removal of a solicitor from the rolls in England and Wales, Scotland, or Northern Ireland is called being "struck off". United States Overview Generally disbarment is imposed as a sanction for conduct indicating that an attorney is not fit to practice law, willfully disregarding the interests of a client, commingling funds, or engaging in fraud which impedes the administration of justice. In addition, any lawyer who is convicted of a felony is automatically disbarred in most jurisdictions, a policy that, although opposed by the American Bar Association, has been described as a convicted felon's just deserts. In the United States legal system, disbarment is specific to regions; one can be disbarred from some courts, while still being a member of the bar in another jurisdiction. However, under the American Bar Association's Model Rules of Professional Conduct, which have been adopted in most states, disbarment in one state or court is grounds for disbarment in a jurisdiction which has adopted the Model Rules. Disbarment is quite rare: in 2011, only 1,046 lawyers were disbarred. Instead, lawyers are usually sanctioned by their own clients through civil malpractice proceedings, or via fine, censure, suspension, or other punishments from the disciplinary boards. To be disbarred is considered a great embarrassment and shame, even if one no longer wishes to continue a career in law. Because disbarment rules vary by area, different rules can apply depending on where a lawyer is disbarred. Notably, the majority of US states have no procedure for permanently disbarring a person. Depending on the jurisdiction, a lawyer may reapply to the bar immediately, after five to seven years, or be banned for life. Notable U.S. disbarments The 20th and the 21st centuries have seen one former U.S. president and one former U.S. vice president disbarred, and another former president suspended from one bar and caused to resign from another bar rather than face disbarment. Former vice president Spiro Agnew, having pleaded no contest (which subjects a person to the same criminal penalties as a guilty plea, but is not an admission of guilt for a civil suit) to charges of bribery and tax evasion, was disbarred from Maryland, the state of which he had previously been governor. Former president Richard Nixon | vice president disbarred, and another former president suspended from one bar and caused to resign from another bar rather than face disbarment. Former vice president Spiro Agnew, having pleaded no contest (which subjects a person to the same criminal penalties as a guilty plea, but is not an admission of guilt for a civil suit) to charges of bribery and tax evasion, was disbarred from Maryland, the state of which he had previously been governor. Former president Richard Nixon was disbarred from New York in 1976 for obstruction of justice related to the Watergate scandal. He had attempted to resign from the New York bar, as he had done with California and the Supreme Court, but his resignation was not accepted as he would not acknowledge that he was unable to defend himself from the charges brought against him. In 2001, following a 5-year suspension by the Arkansas bar, the United States Supreme Court suspended Bill Clinton, providing 40 days for him to contest disbarment. He resigned before the end of the 40 day period, thus avoiding disbarment. Alger Hiss was disbarred for a felony conviction, but later became the first person reinstated to the bar in Massachusetts after disbarment. In 2007, Mike Nifong, the District Attorney of Durham County, North Carolina who presided over the 2006 Duke University lacrosse case, was disbarred for prosecutorial misconduct related to his handling of the case. In April 2012, a three-member panel appointed by the Arizona Supreme Court voted unanimously to disbar Andrew Thomas, former County Attorney of Maricopa County, Arizona, and a former close confederate of Maricopa County Sheriff Joe Arpaio. According to the panel, Thomas "outrageously exploited power, flagrantly fostered fear, and disgracefully misused the law" while serving as Maricopa County Attorney. The panel found "clear and convincing evidence" that Thomas brought unfounded and malicious criminal and civil charges against political opponents, including four state judges and the state attorney general. "Were this a criminal case," the panel concluded, "we are confident that the evidence would establish this conspiracy beyond a reasonable doubt." Jack Thompson, the Florida lawyer noted for his activism against Howard Stern, video games, and rap music, was permanently disbarred for various charges of misconduct. The action was the result of several grievances claiming that Thompson had |
not uncommon for a soldier to be issued one tag with the notch and one tag without. Notched tags are still in production, to satisfy the needs of hobbyists, film production, etc., while the Model 70 imprinter has become a rare collector's item. It appears instructions that would confirm the notch's mythical use were issued at least unofficially by the Graves Registration Service during the Vietnam War to Army troops headed overseas. Dog tags are traditionally part of the makeshift battlefield memorials soldiers created for their fallen comrades. The casualty's rifle with bayonet affixed is stood vertically atop the empty boots, with the helmet over the rifle's stock. The dog tags hang from the rifle's handle or trigger guard. Non-military usage Medical condition identification Some tags (along with similar items such as MedicAlert bracelets) are used also by civilians to identify their wearers and specify them as having health problems that may (a) suddenly incapacitate their wearers and render them incapable of providing treatment guidance (as in the cases of heart problems, epilepsy, diabetic coma, accident or major trauma) and/or (b) interact adversely with medical treatments, especially standard or "first-line" ones (as in the case of an allergy to common medications) and/or (c) provide in case of emergency ("ICE") contact information and/or (d) state a religious, moral, or other objection to artificial resuscitation, if a first responder attempts to administer such treatment when the wearer is non-responsive and thus unable to warn against doing so. A DNR signed by a physician is still required in some states. Military personnel in some jurisdiction may wear a supplementary medical information tag. Fashion Dog tags have found their way into youth fashion by way of military chic. Originally worn as a part of a military uniform by youth wishing to present a tough or militaristic image, dog tags have since seeped out into wider fashion circles. They may be inscribed with a person's details, their beliefs or tastes, a favorite quote, or may bear the name or logo of a band or performer. Since the late 1990s, custom dog tags have been fashionable amongst musicians (particularly rappers), and as a marketing give-away item. Numerous companies offer customers the opportunity to create their own personalized dog tags with their own photos, logos, and text. Even high-end jewelers have featured gold and silver dog tags encrusted with diamonds and other jewels. Variations by country Austria The Austrian Bundesheer used a single long, rectangular tag, with oval ends, stamped with blood group & Rh factor at the end, with ID number underneath. Two slots and a hole stamped beneath allows the tag to be broken in halves, and the long bottom portion has both the ID number and a series of holes which allows the tag to be inserted into a dosimeter. This has been replaced with a more conventional, wider and rounded rectangle which can still be halved, but lacks the dosimeter reading holes. Australia The Australian Defence Force issues soldiers two tags of different shapes, one octagonal and one circular, containing the following information: AS (denoting Australia, previously both AU and AUST have been used) PMKeyS/Service number First initial Last name Religious abbreviation (e.g. RC – Roman Catholic, NREL – No religion) Blood group The information is printed exactly the same on both discs. In the event of a casualty, the circular tag is removed from the body. Belgium Belgian Forces identity tags are, like the Canadian and Norwegian, designed to be broken in two in case of fatality; the lower half is returned to Belgian Defence tail, while the upper half remains on the body. The tags contain the following information: Upper half: Belgisch Leger (Belgian Army) and Date of Birth in DD/MM/YYYY format. Surname with the addition of the first letter of given name. Service number and blood group with RH factor and optionally religion. Lower half: identical. Example: Belgisch Leger 01/01/1991 Surname J 1234567 O+ KATH Canada Canadian Forces identity discs (abbreviated "I discs") are designed to be broken in two in the case of fatality; the lower half is returned to National Defence Headquarters with the member's personal documents, while the upper half remains on the body. The tags contain the following information: Upper half: Service Number (SN) Initials and surname Religion (or "NRE" if none) and blood group with RH factor The legend "CDN FORCES CDN" (or for foreign nationals, the name of the country the individual represents) The text "DO NOT REMOVE / NE PAS ENLEVER" on the reverse Lower half: identical, except the reverse is blank and blood group is not included. Before the Service Number was introduced in the 1990s, military personnel were identified on the I discs (as well as other documents) by their Social Insurance Number. China The People's Liberation Army issues two long, rectangular tags. All information is stamped in Simplified Chinese: Full name Gender Date of birth RIC number PLA's ID number Blood type Branch PLA is introducing a two-dimensional matrix code on the second tag, the matrix code contains a link to the official database. This allows the inquirer get more details about the military personnel. Colombia The Ejército Nacional de Colombia uses long, rectangular metal tags with oval ends tags stamped with the following information: Family Name First Name Military ID Number Blood Type Branch of Service Duplicate tags are issued. Often, tags are issued with a prayer inscribed on the reverse. Cyprus In Cyprus, identification tags include the following information: Surname First name Service number (E.g., 11111/00/00B, where the first five digits are the ID, the second two are the year the soldier turned 18 years old, the last two digits are the year the soldier enlisted, and the letter is the enlistment group, either A or B) Blood Group Denmark The military of Denmark use dog tags made from small, rectangular metal plates. The tag is designed to be broken into two pieces each with the following information stamped onto it: Personal identification number Surname First name Additionally, the right hand side of each half-tag is engraved 'DANMARK', . Starting in 1985, the individual's service number (which is the same as the social security number) is included on the tag. In case the individual dies, the lower half-tag is supposed to be collected, while the other will remain with the corpse. In the army, navy, and air force but not in the national guard, the individual's blood type is indicated on the lower half-tag only, since this information becomes irrelevant if the individual dies. In 2009, Danish dog tags were discontinued for conscripts. East Germany The Nationale Volksarmee used a tag nearly identical to that used by both the Wehrmacht and the West German Bundeswehr. The oval aluminum tag was stamped "DDR" (Deutsche Demokratische Republik) above the personal ID number; this information was repeated on the bottom half, which was intended to be broken off in case of death. Oddly, the tag was not worn, but required to be kept in a plastic sleeve in the back of the WDA identity booklet. Ecuador The Placas de identificación de campaña consists of two long, rectangular steel or aluminum tags with rounded corners and a single hole punched in one end. It is suspended by a US-type ball chain, with a shorter chain for the second tag.

The ball chain is of X5CrNi1810, diameter of ball is 3.5 mm, that of the wire 1.5 mm. Closure is of 1.4301, stainless steel, too. The long chain is 680 + 30 mm long, the short one 145 + 7 mm. Breaking force of the chain including the closure must reach 100 N, after 10 min glow at 1200 °C in air at least 10 N. Greece In Greece, identification tags include the following information: Surname First name Service number (where date of birth is included as "class") Blood Group Hungary The Hungarian army dog tag is made out of steel, forming a 25×35 mm tag designed to split diagonally. Both sides contain the same information: the soldier's personal identity code, blood group and the word HUNGARIA. Some may not have the blood group on them. These are only issued to soldiers who are serving outside of the country. If the soldier should die, one side is removed and kept for the army's official records, while the other side is left attached to the body. Iraq The Saddam-era Iraqi Army used a single, long, rectangular metal tag with oval ends, inscribed (usually by hand) with Name and Number or Unit, and occasionally Blood Type. Israel Dog tags of the Israel Defense Forces are designed to be broken in two. The information appears in three lines (twice): Army identification number ("mispar ishi", literally "personal number". A seven-digit number that is different from the nine-digit identification number for citizens). Last name First Name Blood Type (ABO group - in some years) Recruits are issued with 2 Dogtags (4 halves total), one remains whole and worn on a necklace, and the second is broken into its halves and placed in each military boot for the purpose of Identifying dead soldiers (IDF Military Boots contain pouches on their inner sides at the 1/3 calf height, the pouches have holes corresponding in size and placement to those on the discs, allowing for fastening, often via small cable ties). Originally the IDF issued two circular aluminum tags (1948 – late 1950s) stamped in three lines with serial number, family name, and first name. The tags were threaded together through a single hole onto a cord worn around the neck. Italy Rectangular piece, 35x45 mm, designed to be broken in two. Includes soldier's first and last name, coded date and place of birth, identification number, religious affiliation, and blood group. Japan Japan follows a similar system to the US Army for its Japan Self-Defense Forces personnel, and the appearance of the tags is similar, although laser etched. The exact information order is as follows. Japan Ground Self-Defense Force JAPAN GSDF First name, last name Identification number Blood type Japan Maritime Self-Defense Force First name, last name Identification number JAPAN MSDF Blood type Japan Air Self-Defense Force First name, last name Identification number JAPAN ASDF Blood type Malaysia Malaysian Armed Forces have two identical oval tags with this information: NRIC number (The last digit is an odd number for a male soldier, and an even number for a female soldier.) Service number Full name Blood type Religion Branch (e.g., TLDM) If more information needed, another two oval wrist tags are provided. The term wrist tags can be used to refer to the bracelet-like wristwatch. The additional tags only need to be worn on the wrist, with the main tags still on the neck. All personnel are allowed to attach a small religious pendant or locket; this makes a quick identifiable reference for their funeral services. Mexico The Mexican Army uses two long identity tags, very similar to the ones used in the United States Army. They are rectangular metal tags with oval ends, embossed with name, serial number, and blood type, plus Rh factor. Netherlands Dutch military identity tags, like the Canadian and Norwegian ones, are designed to be broken in two in case of a fatality; the lower end is returned to Dutch Defence Headquarters, while the upper half remains on the body. The tags contain the following information: Upper half: Name and family name Service number Nationality and religion Blood group with RH factor Lower half: identical. There is a difference in the Army and Air Force service number and the Navy service number: The Army and Air Force service number is made up of the date of birth in YY.MM.DD. format, for example 83.01.15, and a three-digit number, such as 123. The Navy service number is made up out of random five- or six-digit numbers. Norway Norwegian dog tags are designed to be broken in two like the Canadian and the Dutch version: The top half contains the nationality, the eleven-digit birth number and the blood type. The bottom half contains the nationality and birth number and has a hole so the broken-off half can be hung on a ring.

When the hoop is placed around the drum head and shell and tightened down with tension rods, the tension of the head can be adjusted. When the tension is increased, the amplitude of the sound is reduced and the frequency is increased, making the pitch higher and the volume lower. The type of shell also affects the sound of a drum. Because the vibrations resonate in the shell of the drum, the shell can be used to increase the volume and to manipulate the type of sound produced. The larger the diameter of the shell, the lower the pitch. The larger the depth of the drum, the louder the volume. Shell thickness also determines the volume of drums. Thicker shells produce louder drums. Mahogany raises the frequency of low pitches and keeps higher frequencies at about the same speed. When choosing a set of shells, a jazz drummer may want smaller maple shells, while a rock drummer may want larger birch shells. History Drums made with alligator skins have been found in Neolithic cultures located in China, dating to a period of 5500–2350 BC. In literary records, drums manifested shamanistic characteristics and were often used in ritual ceremonies. The bronze Dong Son drum was fabricated by the Bronze Age Dong Son culture of northern Vietnam. They include the ornate Ngoc Lu drum. Animal drumming Macaque monkeys drum objects in a rhythmic way to show social dominance and this has been shown to be processed in a similar way in their brains to vocalizations, suggesting an evolutionary origin to drumming as part of social communication. Other primates make drumming sounds by chest beating or hand clapping, and rodents such as kangaroo rats also make similar sounds using their paws on the ground. Talking drums Drums are used not only for their musical qualities, but also as a means of communication over great distances. The talking drums of Africa are used to imitate the tone patterns of spoken language. Throughout Sri Lankan history drums have been used for communication between the state and the community, and Sri Lankan drums have a history stretching back over 2500 years. Drums in art Drumming may be a purposeful expression of emotion for entertainment, spiritualism and communication. Many cultures practice drumming as a spiritual or religious passage and interpret drummed rhythm similarly to spoken language or prayer. Drumming has developed over millennia to be a powerful art form. Drumming is commonly viewed as the root of music and is sometimes performed as a kinesthetic dance. As a discipline, drumming concentrates on training the body to punctuate, convey and interpret musical rhythmic intention to an audience and to the performer. Military uses Chinese troops used tàigǔ drums to motivate troops, to help set a marching pace, and to call out orders or announcements. For example, during a war between Qi and Lu in 684 BC, the effect of drum on soldiers' morale is employed to change the result of a major battle. Fife-and-drum corps of Swiss mercenary foot soldiers also used drums. They used an early version of the snare drum carried over the player's right shoulder, suspended by a strap (typically played with one hand using | number of tuning screws called "tension rods" that screw into lugs placed evenly around the circumference. The head's tension can be adjusted by loosening or tightening the rods. Many such drums have six to ten tension rods. The sound of a drum depends on many variables—including shape, shell size and thickness, shell materials, counterhoop material, drumhead material, drumhead tension, drum position, location, and striking velocity and angle. Prior to the invention of tension rods, drum skins were attached and tuned by rope systems—as on the Djembe—or pegs and ropes such as on Ewe drums. These methods are rarely used today, though sometimes appear on regimental marching band snare drums. The head of a talking drum, for example, can be temporarily tightened by squeezing the ropes that connect the top and bottom heads. Similarly, the tabla is tuned by hammering a disc held in place around the drum by ropes stretching from the top to bottom head. Orchestral timpani can be quickly tuned to precise pitches by using a foot pedal. Sound Several factors determine the sound a drum produces, including the type, shape and construction of the drum shell, the type of drum heads it has, and the tension of these drumheads. Different drum sounds have different uses in music. For example, the modern Tom-tom drum. A jazz drummer may want drums that are high pitched, resonant and quiet whereas a rock drummer may prefer drums that are loud, dry and low-pitched. The drum head has the most effect on how a drum sounds. Each type of drum head serves its own musical purpose and has its own unique sound. Double-ply drumheads dampen high frequency harmonics because they are heavier and they are suited to heavy playing. Drum heads with a white, textured coating on them muffle the overtones of the drum head slightly, producing a less diverse pitch. Drum heads with central silver or black dots tend to muffle the overtones even more, while drum heads with perimeter sound rings mostly eliminate overtones. Some jazz drummers avoid using thick drum heads, preferring single ply drum heads or drum heads with no muffling. Rock drummers often prefer the thicker or coated drum heads. The second biggest factor that affects drum sound is head tension against the shell. When the hoop is placed around the drum head and shell and tightened down with tension rods, the tension of the head can be adjusted. When the tension is increased, the amplitude of the sound is reduced and the frequency is increased, making the pitch higher and the volume lower. The type of shell also affects the sound of a drum. Because the vibrations resonate in the shell of the drum, the shell can be used to increase the volume and to manipulate the type of sound produced. The larger the diameter of the shell, the lower the pitch. The larger the depth of the drum, the louder the volume. Shell thickness also determines the volume of drums. Thicker shells produce louder drums. Mahogany raises the frequency of low pitches and keeps higher frequencies at about the same speed.

stated "no Emperor would proceed beyond [Persian capital city] Ctesiphon", and predicted Julian's "apotheosis to Olympos in a fiery chariot"; Gregory points out these oracles were truly the "last" pagan prophecies. Kedrenos notes contemporary Christian discomfort at these oracles after the "last", in claiming the Christian god "allowed temporary reversion to the old order". Julian's siege of Ctesiphon indeed failed and was followed by his death in battle ten (or twelve) days later. The end of his reign also marked the end of the pagan revival project. Excavation The site was first briefly excavated in 1880 by Bernard Haussoullier (1852-1926) on behalf of the French School at Athens, of which he was a sometime member. The site was then occupied by the village of Kastri, about 100 houses, 200 people. Kastri ("fort") had been there since the destruction of the place by Theodosius I in 390. He probably left a fort to make sure it was not repopulated, except that the fort became the new village. They were mining the stone for re-use in their own buildings. British and French travelers visiting the site suspected it was ancient Delphi. Before a systematic excavation of the site could be undertaken, the village had to be relocated but the residents resisted. The opportunity to relocate the village occurred when it was substantially damaged by an earthquake, with villagers offered a completely new village in exchange for the old site. In 1893 the French Archaeological School removed vast quantities of soil from numerous landslides to reveal both the major buildings and structures of the sanctuary of Apollo and of Athena Pronoia along with thousands of objects, inscriptions and sculptures. During the Great Excavation were discovered architectural members from a 5th-century Christian basilica, when Delphi was a bishopric. Other important Late Roman buildings are the Eastern Baths, the house with the peristyle, the Roman Agora, the large cistern usw. At the outskirts of the city there were located late Roman cemeteries. To the southeast of the precinct of Apollo lay the so-called Southeastern Mansion, a building with a 65-meter-long façade, spread over four levels, with four triclinia and private baths. Large storage jars kept the provisions, whereas other pottery vessels and luxury items were discovered in the rooms. Among the finds stands out a tiny leopard made of mother of pearl, possibly of Sassanian origin, on display in the ground floor gallery of the Delphi Archaeological Museum. The mansion dates to the beginning of the 5th century and functioned as a private house until 580, later however it was transformed into a potters' workshop. It is only then, in the beginning of the 6th century, that the city seems to decline: its size is reduced and its trade contacts seem to be drastically diminished. Local pottery production is produced in large quantities: it is coarser and made of reddish clay, aiming at satisfying the needs of the inhabitants. The Sacred Way remained the main street of the settlement, transformed, however, into a street with commercial and industrial use. Around the agora were built workshops as well as the only intra muros early Christian basilica. The domestic area spread mainly in the western part of the settlement. The houses were rather spacious and two large cisterns provided running water to them. Delphi Archaeological Museum The Delphi Archaeological Museum is at the foot of the main archaeological complex, on the east side of the village, and on the north side of the main road. The museum houses artifacts associated with ancient Delphi, including the earliest known notation of a melody, the Charioteer of Delphi, Kleobis and Biton, golden treasures discovered beneath the Sacred Way, the Sphinx of Naxos, and fragments of reliefs from the Siphnian Treasury. Immediately adjacent to the exit is the inscription that mentions the Roman proconsul Gallio. Entries to the museum and to the main complex are separate and chargeable. A reduced rate ticket gets entry to both. There is a small cafe, and a post office by the museum. Architecture of the precinct Most of the ruins that survive today date from the most intense period of activity at the site in the 6th century BC. Temple of Apollo The ruins of the Temple of Delphi visible today date from the 4th century BC, and are of a peripteral Doric building. It was erected by Spintharus, Xenodoros, and Agathon on the remains of an earlier temple, dated to the 6th century BC which itself was erected on the site of a 7th-century BC construction attributed in legend to the architects Trophonios and Agamedes. Ancient tradition accounted for four temples that successively occupied the site before the 548/7 BC fire, following which the Alcmaeonids built a fifth. The poet Pindar celebrated the Alcmaeonids' temple in Pythian 7.8-9 and he also provided details of the third building (Paean 8. 65-75). Other details are given by Pausanias (10.5.9-13) and the Homeric Hymn to Apollo (294 ff.). The first temple was said to have been constructed out of olive branches from Tempe. The second was made by bees out of wax and wings but was miraculously carried off by a powerful wind and deposited among the Hyperboreans. The third, as described by Pindar, was created by the gods Hephaestus and Athena, but its architectural details included Siren-like figures or "Enchantresses", whose baneful songs eventually provoked the Olympian gods to bury the temple in the earth (according to Pausanias, it was destroyed by earthquake and fire). In Pindar's words addressed to the Muses: Muses, what was its fashion, shown By the skill in all arts Of the hands of Hephaestus and Athena? Of bronze the walls, and of bronze Stood the pillars beneath, But of gold were six Enchantresses Who sang above the eagle. But the sons of Cronus Opened the earth with a thunderbolt And hid the holiest of all things made. Away from their children And wives, when they hung Their lives on the honey-hearted words. The fourth temple was said to have been constructed from stone by Trophonius and Agamedes. However, a new theory gives a completely new explanation of the above myth of the four temples of Delphi. Treasuries From the entrance of the upper site, continuing up the slope on the Sacred Way almost to the Temple of Apollo, are a large number of votive statues, and numerous so-called treasuries. These were built by many of the Greek city-states to commemorate victories and to thank the oracle for her advice, which was thought to have contributed to those victories. These buildings held the offerings made to Apollo; these were frequently a "tithe" or tenth of the spoils of a battle. The most impressive is the now-restored Athenian Treasury, built to commemorate their victory at the Battle of Marathon in 490 BC. The Siphnian Treasury was dedicated by the city of Siphnos whose citizens gave a tithe of the yield from their silver mines until the mines came to an abrupt end when the sea flooded the workings. One of the largest of the treasuries was that of Argos. Having built it in the late classical period, the Argives took great pride in establishing their place at Delphi amongst the other city-states. Completed in 380 BC, the treasury seems to draw inspiration mostly from the Temple of Hera located in the Argolis. However, recent analysis of the Archaic elements of the treasury suggest that its founding preceded this. Other identifiable treasuries are those of the Sicyonians, the Boeotians, Massaliots, and the Thebans. Altar of the Chians Located in front of the Temple of Apollo, the main altar of the sanctuary was paid for and built by the people of Chios. It is dated to the 5th century BC by the inscription on its cornice. Made entirely of black marble, except for the base and cornice, the altar would have made a striking impression. It was restored in 1920. Stoa of the Athenians The stoa, or open-sided, covered porch, is placed in an approximately E-W alignment along the base of the polygonal wall retaining the terrace on which the Temple of Apollo sits. There is no archaeological suggestion of a connection to the temple. The stoa opened to the Sacred Way. The nearby presence of the Treasury of the Athenians suggests that this quarter of Delphi was used for Athenian business or politics, as stoas are generally found in market-places. Although the architecture at Delphi is generally Doric, a plain style, in keeping with the Phocian traditions, which were Doric, the Athenians did not prefer the Doric. The stoa was built in their own preferred style, the Ionic order, the capitals of the columns being a sure indicator. In the Ionic order they are floral and ornate, although not as much as the Corinthian, which is in deficit there. The remaining porch structure contains seven fluted columns, unusually carved from single pieces of stone (most columns were constructed from a series of discs joined together). The inscription on the stylobate indicates that it was built by the Athenians after their naval victory over the Persians in 478 BC, to house their war trophies. At that time the Athenians and the Spartans were on the same side. Sibyl rock The Sibyl rock is a pulpit-like outcrop of rock between the Athenian Treasury and the Stoa of the Athenians upon the sacred way which leads up to the temple of Apollo in the archaeological area of Delphi. It is claimed to be where an ancient Sibyl pre-dating the Pythia of Apollo sat to deliver her prophecies. Or, the Pythia might have stood there, or an acolyte whose function was to deliver the final prophecy. The rock seems ideal for public speaking. Theatre The ancient theatre at Delphi was built further up the hill from the Temple of Apollo giving spectators a view of the entire sanctuary and the valley below. It was originally built in the 4th century BC but was remodeled on several occasions, particularly in 160/159 B.C. at the expenses of king Eumenes II of Pergamon and in 67 A.D. on the occasion of emperor Nero's visit. The koilon (cavea) leans against the natural slope of the mountain whereas its eastern part overrides a little torrent that led the water of the fountain Cassotis right underneath the temple of Apollo. The orchestra was initially a full circle with a diameter measuring 7 meters. The rectangular scene building ended up in two arched openings, of which the foundations are preserved today. Access to the theatre was possible through the parodoi, i.e. the side corridors. On the support walls of the parodoi are engraved large numbers of manumission inscriptions recording fictitious sales of the slaves to the god. The koilon was divided horizontally in two zones via a corridor called diazoma. The lower zone had 27 rows of seats and the upper one only 8. Six radially arranged stairs divided the lower part of the koilon in seven tiers. The theatre could accommodate about 4,500 spectators. On the occasion of Nero's visit to Greece in 67 A.D. various alterations took place. The orchestra was paved and delimited by a parapet made of stone. The proscenium was replaced by a low pedestal, the pulpitum; its façade was decorated with scenes from Hercules' myth in relief. Further repairs and transformations took place in the 2nd century A.D. Pausanias mentions that these were carried out under the auspices of Herod Atticus. In antiquity, the theatre was used for the vocal and musical contests which formed part of the programme of the Pythian Games in the late Hellenistic and Roman period. The theatre was abandoned when the sanctuary declined in Late Antiquity. After its excavation and initial restoration it hosted theatrical performances during the Delphic Festivals organized by A. Sikelianos and his wife, Eva Palmer, in 1927 and in 1930. It has recently been restored again as the serious landslides posed a grave threat for its stability for decades. Tholos The tholos at the sanctuary of Athena Pronoia (Ἀθηνᾶ Πρόνοια, "Athena of forethought") is a circular building that was constructed between 380 and 360 BC. It consisted of 20 Doric columns arranged with an exterior diameter of 14.76 meters, with 10 Corinthian columns in the interior. The Tholos is located approximately a half a mile (800 m) from the main ruins at Delphi (at ). Three of the Doric columns have been restored, making it the most popular site at Delphi for tourists to take photographs. The architect of the "vaulted temple at Delphi" is named by Vitruvius, in De architectura Book VII, as Theodorus Phoceus (not Theodorus of Samos, whom Vitruvius names separately). Gymnasium The gymnasium, which is half a mile away from the main sanctuary, was a series of buildings used by the youth of Delphi. The building consisted of two levels: a stoa on the upper level providing open space, and a palaestra, pool and baths on lower floor. These pools and baths were said to have magical powers, and imparted the ability to communicate to Apollo himself. Stadium The stadium is located further up the hill, beyond the via sacra and the theatre. It was originally built in the 5th century BC but was altered in later centuries. The last major remodelling took place in the 2nd century AD under the patronage of Herodes Atticus when the stone seating was built and (arched) entrance. It could seat 6500 spectators and the track was 177 metres long and 25.5 metres wide. Hippodrome It was at the Pythian Games that prominent political leaders, such as Cleisthenes, tyrant of Sikyon, and Hieron, tyrant of Syracuse, competed with their chariots. The hippodrome where these events took place was referred to by Pindar, and this monument was sought by archaeologists for over two centuries. Its traces have recently been found at Gonia in the plain of Krisa in the place where the original stadium was sited. Polygonal wall The retaining wall was built to support the terrace housing the construction of the second temple of Apollo in 548 BC. Its name is taken from the polygonal masonry of which it is constructed. At a later date, from 200 BC onwards, the stones were inscribed with the manumission (libration) contracts of slaves who were consecrated to Apollo. Approximately a thousand manumissions are recorded on the wall. Castalian spring The sacred spring of Delphi lies in the ravine of the Phaedriades. The preserved remains of two monumental fountains that received the water from the spring date to the Archaic period and the Roman, with the latter cut into the rock. Athletic statues Delphi is famous for its many preserved athletic statues. It is known that Olympia originally housed far more of these statues, but time brought ruin to many of them, leaving Delphi as the main site of athletic statues. Kleobis and Biton, two brothers renowned for their strength, are modeled in two of the earliest known athletic statues at Delphi. The statues commemorate their feat of pulling their mother's cart several miles to the Sanctuary of Hera in the absence of oxen. The neighbors were most impressed and their mother asked Hera to grant them the greatest gift. When they entered Hera's temple, they fell into a slumber and never woke, dying at the height of their admiration, the perfect gift. The Charioteer of Delphi is another ancient relic that has withstood the centuries. It is one of the best known statues from antiquity. The charioteer has lost many features, including his chariot and his left arm, but he stands as a tribute to athletic art of antiquity. Myths regarding the origin of the precinct A myth is a story based on fantasy or belief rather than known fact. Ancient Greek culture used them frequently in many different contexts. They are only known to moderns through mention in ancient Greek writings. A writer typically had access to writings at a library or private archive, unless he was wealthy enough to have his own copies made. All books were hand-written. Authors referred to other authors whose books they had before them, or had taken notes from. Often the source of the story was not identified, but even if it was, the source may have taken it from some other book. Sometimes authors wrote down myths related to them orally. It is thus not possible to date myths. They could have come from any prior time. Often the date of the book relating the myth cannot be determined within centuries. A myth cannot with any certainty be attributed to any century, although the written source may be. Scholars are not entirely without dating methods, however. The content of the myth may resemble or imply circumstances of known or probable provenience. The Iliad, for example, most likely relates myths passed down from the Trojan War, a known Late Bronze Age event. The Greeks were aided and abetted in their myth-making by the oracles in which they typically devoutly believed. When asked a question, an oracle never gave a direct answer, but spoke in allegories with "hidden meanings" and "ambiguities," said Plutarch, priest of Apollo and historian. It was then incumbent on the inquiring party to interpret them. As the prophecy was regarded as the true word of divinity, the actual meaning, if it could be known, must be historical truth. Believing this principle to be true, many of the best historians spent time trying to intepret oracular myths as actual circumstances. Some Temple of Apollo appears in the Homeric Literature. In the Iliad, Achilles would not accept Agamemnon's peace offering even if it included all the wealth in the "stone floor" of "rocky Pytho" (I 404). In the Odyssey (θ 79) Agamemnon crosses a "stone floor" to receive a prophecy from Apollo in Pytho, the first known of proto-history. Hesiod also refers to Pytho "in the hollows of Parnassus" (Theogony 498). These references imply that the earliest known date of the oracle's existence is the 8th century BC, the probable date of composition of the Homeric works. Earlier times of existence cannot be excluded if the written poems are adaptations of earlier oral ones. Beyond these proto-historic tidbits the main myths of Delphi are given in three literary loci. H.W Parke, the Delphi scholar, complained that they are self-contradictory, thus unconsciously falling into the Plutarchian epistemology, that they reflect some common, objective historic reality against which the accounts can be compared. Missing is the reality, nor can it be assumed ever to have existed. There is no Apollo, no Zeus, no Hera, and certainly never was a great, serpent-like monster. The myths are pure Plutarchian figures of speech, meant to be aetiologies of some oracular tradition. Homeric Hymn 3, "To Apollo," is the oldest of the three loci, dating to the 7th century BC (estimate). Apollo travels about after his birth on Delos seeking a place for an oracle. He is advised by Telephus to choose Crissa "below the glade of Parnassus," which he does, and has a temple built. Killing the serpent that guards the spring. Subsequently, some Cretans from Knossos sail up on a mission to reconnoitre Pylos. Changing into a dolphin, Apollo casts himself on deck. The Cretans do not dare to remove him but sail on. Apollo guides the ship around Greece, ending back at Crisa, where the ship grounds. Apollo enters his shrine with the Cretans to be its priests, worshipping him as Delphineus, "of the dolphin." Zeus determined the site of Delphi when he sought to find the centre of his "Grandmother Earth" (Gaia). He sent two eagles flying from the eastern and western extremities, and the path of the eagles crossed over Delphi where the omphalos, or navel of Gaia was found. According to Aeschylus in the prologue of the Eumenides, the oracle had origins in prehistoric times and the worship of Gaia, a view echoed by H.W. Parke. One tale of the sanctuary's discovery states that a goatherd, who grazed his flocks on Parnassus, one day observed his goats playing with great agility upon nearing a chasm in the rock; the goatherd noticing this held his head over the chasm causing the fumes to go to his brain; throwing him into a strange trance. The Homeric Hymn to Delphic Apollo recalled that the ancient name of this site had been Krisa. Others relate that it was named Pytho (Πυθώ) and that Pythia, the priestess serving as the oracle, was chosen from their ranks by a group of priestesses who officiated at the temple. Apollo was said to have slain Python, a drako (a male serpent or a dragon) who lived there and protected the navel of the Earth. "Python" (derived from the verb πύθω (pythō), "to rot") is claimed by some to be the original name of the site in recognition of Python which Apollo defeated. The name Delphi comes from the same root as δελφύς delphys, "womb" and may indicate archaic veneration of Gaia at the site. Apollo is connected with the site by his epithet Δελφίνιος Delphinios, "the Delphinian". The epithet is connected with dolphins (Greek δελφίς,-ῖνος) in the Homeric Hymn to Apollo (line 400), recounting the legend of how Apollo first came to Delphi in the shape of a dolphin, carrying Cretan priests on his back. The Homeric name of the oracle is Pytho (Πυθώ). Another legend held that Apollo walked to Delphi from the north and stopped at Tempe, a city in Thessaly, to pick laurel (also known as bay tree) which he considered to be a sacred plant. In commemoration of this legend, the winners at the Pythian Games received a wreath of laurel picked in the temple. Oracle of Delphi The prophetic process Delphi is perhaps best known for its oracle, the Pythia, or sibyl, the duty priestess prophesying from the tripod in the sunken adyton of the Temple of Apollo. Apollo spoke through his oracle. She had to be an older woman of blameless life chosen from among the peasants of the area. Alone in an enclosed inner sanctum (Ancient Greek adyton – "do not enter") she sat on a tripod seat over an opening in the earth (the "chasm"). According to legend, when Apollo slew Python its body fell into this fissure and fumes arose from its decomposing body. Intoxicated by the vapors, the sibyl would fall into a trance, allowing Apollo to possess her spirit. In this state she prophesied. The oracle could not be consulted during the winter months, for this was traditionally the time when Apollo | spring The sacred spring of Delphi lies in the ravine of the Phaedriades.

Apollo spoke through his oracle. She had to be an older woman of blameless life chosen from among the peasants of the area.

Intoxicated by the vapors, the sibyl would fall into a trance, allowing Apollo to possess her spirit. In this state she prophesied. The oracle could not be consulted during the winter months, for this was traditionally the time when Apollo would live among the Hyperboreans. Dionysus would inhabit the temple during his absence. The time to consult pythia for an oracle during the year is determined from astronomical and geological grounds related to the constellations of Lyra and Cygnus but the hydrocarbon vapors emitted from the chasm. Similar practice was followed in other Apollo oracles too. While in a trance the Pythia "raved" – probably a form of ecstatic speech – and her ravings were "translated" by the priests of the temple into elegant hexameters. It has been speculated that the ancient writers, including Plutarch who had worked as a priest at Delphi, were correct in attributing the oracular effects to the sweet-smelling pneuma (Ancient Greek for breath, wind or vapor) escaping from the chasm in the rock. That exhalation could have been high in the known anaesthetic and sweet-smelling ethylene or other hydrocarbons such as ethane known to produce violent trances. Though this theory remains debatable the authors put up a detailed answer to their critics. Ancient sources describe the priestess using “laurel” to inspire her prophecies. Several alternative plant candidates have been suggested including Cannabis, Hyoscyamus, Rhododendron and Oleander. Harissis claims that a review of contemporary toxicological literature indicates that oleander causes symptoms similar to those shown by the Pythia, and his study of ancient texts shows that oleander was often included under the term "laurel". The Pythia may have chewed oleander leaves and inhaled their smoke prior to her oracular pronouncements and sometimes dying from the toxicity. The toxic substances of oleander resulted in symptoms similar to those of epilepsy, the “sacred disease,” which may have been seen as the possession of the Pythia by the spirit of Apollo. The Delphic oracle exerted considerable influence throughout the Greek world, and she was consulted before all major undertakings including wars and the founding of colonies. She also was respected by the Greek-influenced countries around the periphery of the Greek world, such as Lydia, Caria, and even Egypt. The oracle was also known to the early Romans. Rome's seventh and last king, Lucius Tarquinius Superbus, after witnessing a snake near his palace, sent a delegation including two of his sons to consult the oracle. In 83 BCE a Thracian tribe raided Delphi, burned the temple, plundered the sanctuary and stole the "unquenchable fire" from the altar. During the raid, part of the temple roof collapsed. The same year, the temple was severely damaged by an earthquake, thus it fell into decay and the surrounding area became impoverished. The sparse local population led to difficulties in filling the posts required. The oracle's credibility waned due to doubtful predictions. The oracle flourished again in the second century CE during the rule of emperor Hadrian, who is believed to have visited the oracle twice and offered complete autonomy to the city. By the 4th century, Delphi had acquired the status of a city. Despite the rise of Christianity across the Roman Empire, the oracle remained a religious center throughout the 4th century, and the Pythian Games continued to be held at least until 424 CE; however, the decline continued. The attempt of Emperor Julian to revive polytheism did not survive his reign. Excavations have revealed a large three-aisled basilica in the city, as well as traces of a church building in the sanctuary's gymnasium. The site was abandoned in the 6th or 7th centuries, although a single bishop of Delphi is attested in an episcopal list of the late 8th and early 9th centuries. Religious significance of the oracle Delphi became the site of a major temple to Phoebus Apollo, as well as the Pythian Games and the prehistoric oracle. Even in Roman times, hundreds of votive statues remained, described by Pliny the Younger and seen by Pausanias. Carved into the temple were three phrases: (gnōthi seautón = "know thyself") and (mēdén ágan = "nothing in excess"), and (engýa pára d'atē = "make a pledge and mischief is nigh"), In antiquity, the origin of these phrases was attributed to one or more of the Seven Sages of Greece by authors such as Plato and Pausanias. Additionally, according to Plutarch's essay on the meaning of the "E at Delphi"—the only literary source for the inscription—there was also inscribed at the temple a large letter E. Among other things epsilon signifies the number 5. However, ancient as well as modern scholars have doubted the legitimacy of such inscriptions. According to one pair of scholars, "The actual authorship of the three maxims set up on the Delphian temple may be left uncertain. Most likely they were popular proverbs, which tended later to be attributed to particular sages." According to the Homeric hymn to the Pythian Apollo, Apollo shot his first arrow as an infant which effectively slew the serpent Pytho, the son of Gaia, who guarded the spot. To atone the murder of Gaia's son, Apollo was forced to fly and spend eight years in menial service before he could return forgiven. A festival, the Septeria, was held every year, at which the whole story was represented: the slaying of the serpent, and the flight, atonement, and return of the god. The Pythian Games took place every four years to commemorate Apollo's victory. Another regular Delphi festival was the "Theophania" (Θεοφάνεια), an annual festival in spring celebrating the return of Apollo from his winter quarters in Hyperborea. The culmination of the festival was a display of an image of the gods, usually hidden in the sanctuary, to worshippers. The theoxenia was held each summer, centred on a feast for "gods and ambassadors from other states." Myths indicate that Apollo killed the chthonic serpent Python guarding the Castalian Spring and named his priestess Pythia after her. Python, who had been sent by Hera, had attempted to prevent Leto, while she was pregnant with Apollo and Artemis, from giving birth. This spring flowed toward the temple but disappeared beneath, creating a cleft which emitted chemical vapors that purportedly caused the oracle at Delphi to reveal her prophecies. Apollo killed Python but had to be punished for it, since he was a child of Gaia. The shrine dedicated to Apollo was originally dedicated to Gaia and shared with Poseidon. The name Pythia remained as the title of the Delphic oracle. Erwin Rohde wrote that the Python was an earth spirit, who was conquered by Apollo, and buried under the omphalos, and that it is a case of one deity setting up a temple on the grave of another. Another view holds that Apollo was a fairly recent addition to the Greek pantheon coming originally from Lydia. The Etruscans coming from northern Anatolia also worshipped Apollo, and it may be that he was originally identical with Mesopotamian Aplu, an Akkadian title meaning "son", originally given to the plague God Nergal, son of Enlil. Apollo Smintheus (Greek ), the mouse killer eliminates mice, a primary cause of disease, hence he promotes preventive medicine. History Occupation of the site at Delphi can be traced back to the Neolithic period with extensive occupation and use beginning in the Mycenaean period (1600–1100 BC). In Mycenaean times Krissa was a major Greek land and sea power, perhaps one of the first in Greece, if the Early Helladic date of Kirra is to be believed. The ancient sources indicate that the previous name of the Gulf of Corinth was the "Krisaean Gulf." Like Krisa, Corinth was a Dorian state, and Gulf of Corinth was a Dorian lake, so to speak, especially since the migration of Dorians into the Peloponnesus starting about 1000 BC. Krisa's power was broken finally by the recovered Aeolic and Attic-Ionic speaking states of southern Greece over the issue of access to Delphi. Control of it was assumed by the Amphictyonic League, an organization of states with an interest in Delphi, in the early classical period. Krisa was destroyed for its arrogance. The gulf was given Corinth's name. Corinth by then was like the Ionic states: ornate and innovative, not like the spartan style of the Doric. Ancient Delphi Earlier myths include traditions that Pythia, or the Delphic oracle, already was the site of an important oracle in the pre-classical Greek world (as early as 1400 BC) and, rededicated from about 800 BC, when it served as the major site during classical times for the worship of the god Apollo. Delphi was since ancient times a place of worship for Gaia, the mother goddess connected with fertility. The town started to gain pan-Hellenic relevance as both a shrine and an oracle in the 7th century BC. Initially under the control of Phocaean settlers based in nearby Kirra (currently Itea), Delphi was reclaimed by the Athenians during the First Sacred War (597–585 BC). The conflict resulted in the consolidation of the Amphictyonic League, which had both a military and a religious function revolving around the protection of the Temple of Apollo. This shrine was destroyed by fire in 548 BC and then fell under the control of the Alcmaeonids banned from Athens. In 449–448 BC, the Second Sacred War (fought in the wider context of the First Peloponnesian War between the Peloponnesian League led by Sparta and the Delian-Attic League led by Athens) resulted in the Phocians gaining control of Delphi and the management of the Pythian Games. In 356 BC the Phocians under Philomelos captured and sacked Delphi, leading to the Third Sacred War (356–346 BC), which ended with the defeat of the former and the rise of Macedon under the reign of Philip II. This led to the Fourth Sacred War (339 BC), which culminated in the Battle of Chaeronea (338 BC) and the establishment of Macedonian rule over Greece. In Delphi, Macedonian rule was superseded by the Aetolians in 279 BC, when a Gallic invasion was repelled, and by the Romans in 191 BC. The site was sacked by Lucius Cornelius Sulla in 86 BC, during the Mithridatic Wars, and by Nero in 66 AD. Although subsequent Roman emperors of the Flavian dynasty contributed towards to the restoration of the site, it gradually lost importance. In the course of the 3rd century mystery cults became more popular than the traditional Greek pantheon. Christianity, which started as yet one more mystery cult, soon gained ground, and this eventually resulted in the persecution of pagans in the late Roman Empire. The anti-pagan legislation of the Flavian dynasty deprived ancient sanctuaries of their assets. The emperor Julian attempted to reverse this religious climate, yet his "pagan revival" was particularly short-lived. When the doctor Oreibasius visited the oracle of Delphi, in order to question the fate of paganism, he received a pessimistic answer: [Tell the king that the flute has fallen to the ground. Phoebus does not have a home any more, neither an oracular laurel, nor a speaking fountain, because the talking water has dried out.] It was shut down during the persecution of pagans in the late Roman Empire by Theodosius I in 381 AD. Amphictyonic Council The Amphictyonic Council was a council of representatives from six Greek tribes that controlled Delphi and also the quadrennial Pythian Games. They met biannually and came from Thessaly and central Greece. Over time, the town of Delphi gained more control of itself and the council lost much of its influence. The sacred precinct in the Iron Age Excavation at Delphi, which was a post-Mycenaean settlement of the late 9th century, has uncovered artifacts increasing steadily in volume beginning with the last quarter of the 8th century BC. Pottery and bronze as well as tripod dedications continue in a steady stream, in contrast to Olympia. Neither the range of objects nor the presence of prestigious dedications proves that Delphi was a focus of attention for a wide range of worshippers, but the large quantity of valuable goods, found in no other mainland sanctuary, encourages that view. Apollo's sacred precinct in Delphi was a Panhellenic Sanctuary, where every four years, starting in 586 BC athletes from all over the Greek world competed in the Pythian Games, one of the four Panhellenic Games, precursors of the Modern Olympics. |
the minicomputer market starting in the mid-1960s. The company produced a series of machines known as the PDP line, with the PDP-8 and PDP-11 being among the most successful minis in history. Their success was only surpassed by another DEC product, the late-1970s VAX "supermini" systems that were designed to replace the PDP-11. Although a number of competitors had successfully competed with Digital through the 1970s, the VAX cemented the company's place as a leading vendor in the computer space. As microcomputers improved in the late 1980s, especially with the introduction of RISC-based workstation machines, the performance niche of the minicomputer was rapidly eroded. By the early 1990s, the company was in turmoil as their mini sales collapsed and their attempts to address this by entering the high-end market with machines like the VAX 9000 were market failures. After several attempts to enter the workstation and file server market, the DEC Alpha product line began to make successful inroads in the mid-1990s, but was too late to save the company. DEC was acquired in June 1998 by Compaq in what was at that time the largest merger in the history of the computer industry. During the purchase, some parts of DEC were sold to other companies; the compiler business and the Hudson, Massachusetts facility, were sold to Intel. At the time, Compaq was focused on the enterprise market and had recently purchased several other large vendors. DEC was a major player overseas where Compaq had less presence. However, Compaq had little idea what to do with its acquisitions, and soon found itself in financial difficulty of its own. The company subsequently merged with Hewlett-Packard (HP) in May 2002. , decades-old hardware (including PDP-11, VAX, and AlphaServer) is being emulated to allow legacy software to run on modern hardware; funding for this is planned to last at least until 2030. History From 1957 until 1992, DEC's headquarters were located in a former wool mill in Maynard, Massachusetts. The headquarters buildings were vacated in 1993, renamed Clock Tower Place, and subsequently redeveloped as Mill & Main Place, a 1.1 million square foot facility for offices and light industry. Initially focusing on the small end of the computer market allowed DEC to grow without its potential competitors making serious efforts to compete with them. Their PDP series of machines became popular in the 1960s, especially the PDP-8, widely considered to be the first successful minicomputer. Looking to simplify and update their line, DEC replaced most of their smaller machines with the PDP-11 in 1970, the year they became the third largest computer manufacturer after IBM and the UNIVAC Division of Sperry Rand. The rising corporation eventually sold over 600,000 PDP-11s. Originally designed as a follow-on to the PDP-11, DEC's VAX-11 series was the first widely used 32-bit minicomputer, sometimes referred to as "superminis". These systems were able to compete in many roles with larger mainframe computers, such as the IBM System/370. The VAX was a best-seller, with over 400,000 sold, and its sales through the 1980s propelled DEC to become the second largest computer company in the industry. At its peak, it was the second largest employer in Massachusetts, after the state government. The rapid rise of the business microcomputer in the late 1980s, and especially the introduction of powerful 32-bit systems in the 1990s, quickly eroded the value of DEC's systems. DEC's last major attempt to find a space in the rapidly changing market was the DEC Alpha 64-bit RISC instruction set architecture. DEC initially started work on Alpha as a way to re-implement their VAX series, but also employed it in a range of high-performance workstations. Although the Alpha processor family met both of these goals, and, for most of its lifetime, was the fastest processor family on the market, extremely high asking prices were outsold by lower priced workstation chips from Intel and IBM/Motorola. DEC was acquired in June 1998 by | major American company in the computer industry from the 1960s to the 1990s. The company was co-founded by Ken Olsen and Harlan Anderson in 1957. Olsen was president until forced to resign in 1992, after the company had gone into precipitous decline. Although the company produced many different product lines over its history, it is best known for the work in the minicomputer market starting in the mid-1960s. The company produced a series of machines known as the PDP line, with the PDP-8 and PDP-11 being among the most successful minis in history. Their success was only surpassed by another DEC product, the late-1970s VAX "supermini" systems that were designed to replace the PDP-11. Although a number of competitors had successfully competed with Digital through the 1970s, the VAX cemented the company's place as a leading vendor in the computer space. As microcomputers improved in the late 1980s, especially with the introduction of RISC-based workstation machines, the performance niche of the minicomputer was rapidly eroded. By the early 1990s, the company was in turmoil as their mini sales collapsed and their attempts to address this by entering the high-end market with machines like the VAX 9000 were market failures. After several attempts to enter the workstation and file server market, the DEC Alpha product line began to make successful inroads in the mid-1990s, but was too late to save the company.

Products Beyond DECsystem-10/20, PDP, VAX and Alpha, DEC was known for its work in communication subsystem designs, such as Ethernet, DNA (DIGITAL Network Architecture: predominantly DECnet products), DSA (Digital Storage Architecture: disks/tapes/controllers), and its "dumb terminal" subsystems including VT100 and DECserver products. Research DEC's Research Laboratories (or Research Labs, as they were commonly known) conducted DEC's corporate research. Some of them were continued in operation by Compaq and are still operated by Hewlett-Packard. The laboratories were: Cambridge Research Laboratory (CRL) in Cambridge, Massachusetts, US MetroWest Technology Campus (MTC) in Maynard, Massachusetts, US Network Systems Laboratory (NSL) in Palo Alto, California, US Systems Research Center (SRC) in Palo Alto, California, US Paris Research Laboratory (PRL) in Paris, France Western |
and songs such as "Moral Majority", "Nazi Punks Fuck Off!" and "We've Got a Bigger Problem Now" placed Dead Kennedys as the spokesmen of social protest, while "Dog Bite", a cover version of Rawhide and various joke introductions showed a much more whimsical side. In 1982, they released their second studio album, Plastic Surgery Disasters. The album's cover features a withered starving African child's hand being held and dwarfed by a white man's hand, a picture that had won the World Press Photo award in 1980, taken in Karamoja district in Uganda by Mike Wells. The band's music had evolved considerably in a short time, moving away from hardcore formulae toward a more innovative jazz-informed style, featuring musicianship and dynamics far beyond other bands in the genre (thus effectively removing the music from that genre). By now the group had become a de facto political force, pitting itself against rising elements of American social and political life such as the religious right, Ronald Reagan and the idle rich. The band continued touring all over the United States, as well as Europe and Australia, and gained a large underground following. While they continued to play live shows during 1983 and 1984, they took a break from releasing new records to concentrate on the Alternative Tentacles record label, which would become synonymous with DIY alternative culture. The band continued to write and perform new material during this time, which would appear on their next album (some of these early performances can be seen in the DMPO's on Broadway video, originally released by Dirk Dirksen and later reissued on Rhino). Frankenchrist and obscenity trial (1985–1986) The release of the album Frankenchrist in 1985 showed the band had grown in musical proficiency and lyrical maturity. While there were still a number of loud/fast songs, much of the music featured an eclectic mix of instruments including trumpets and synthesizers. Around this time Klaus Flouride released the similarly experimental solo EP Cha Cha Cha With Mr. Flouride. Lyrically, the band continued their trademark social commentary, with songs such as "MTV Get Off The Air" and "Jock-O-Rama (Invasion of the Beef Patrol)" poking fun at mainstream America. However, the controversy that erupted over H.R. Giger's "Penis Landscape", included as an insert with the album, dwarfed the notoriety of its music. The artwork caused a furor with the newly formed Parents Music Resource Center (PMRC). In December 1985 a teenage girl purchased the album at the Wherehouse Records store in Los Angeles County. The girl's mother wrote letters of complaint to the California Attorney General and to Los Angeles prosecutors. In 1986, members of the band, along with other parties involved in the distribution of Frankenchrist, were charged criminally with distribution of harmful matter to minors. The store where the teen actually purchased the album was never named in the lawsuit. The criminal charges focused on an illustration by H.R. Giger, titled "Work 219: Landscape XX" (also known as Penis Landscape). Included as a poster with the album, Penis Landscape depicts nine copulating penises and vaginas. Members of the band and others in the chain of distribution were charged with violating the California Penal Code on a misdemeanor charge carrying a maximum penalty of up to a year in county jail and a base fine of up to $2,000. Biafra says that during this time government agents invaded and searched his home. The prosecution tried to present the poster to the jury in isolation for consideration as obscene material, but Judge Susan Isacoff ruled that the poster must be considered along with the music and lyrics. The charges against three of the original defendants, Ruth Schwartz (owner of Mordam Records), Steve Boudreau (a distributor involved in supplying Frankenchrist to the Los Angeles Wherehouse store), and Salvatore Alberti (owner of the factory where the record was pressed), were dismissed for lack of evidence. In August 1987, the case went to the jury with two remaining defendants: Jello Biafra and Michael Bonanno (former Alternative Tentacles label manager). However, the criminal trial ended with a hung jury, split 7 to 5 in favor of acquittal. District Attorneys Michael Guarino and Ira Riener made a motion for a retrial which was denied by Judge Isacoff, Superior Court Judge for the County of Los Angeles. The album, however, was banned from many record stores nationwide. After the break up of the band, Jello Biafra brought up the court case on The Oprah Winfrey Show. Biafra was on the show with Tipper Gore as part of a panel discussion on the issues of "controversial music lyrics" and censorship. Bedtime for Democracy and break-up (1986) In addition to the obscenity lawsuit, the band became increasingly disillusioned with the underground scene as well. The hardcore scene, which had been a haven for free-thinking intellectuals and downtrodden nonconformists, was attracting a more violent audience that imposed an increasing level of brutality on other concertgoers and began to alienate many of the bands and individuals who had helped pioneer the movement in the early 1980s. In earlier years the band had criticized neo-Nazi skinheads for trying to ruin the punk scene, but just as big a problem was the popularity of increasingly macho hardcore bands, which brought the group (and their genre) an audience that had little to do with the ideas/ideals they stood for. In January 1986, frustrated and alienated from their own scene, Dead Kennedys decided to break up to pursue other interests and played their last concert on February 21. The band continued to work on songs, with Biafra penning songs such as "Chickenshit Conformist" and "Anarchy for Sale", which articulated their feelings about the "dumbing down" of punk rock. During the summer they recorded these songs for their final album, Bedtime for Democracy, which was released in November. The artwork, depicting a defaced Statue of Liberty overrun with Nazis, media, opportunists, Klan members, corrupt government officials, and religious zombies, echoed the idea that neither America itself or the punk scene were safe havens any more for "your tired, your poor, your huddled masses yearning to breathe free". The album contains a number of fast/short songs interspersed with jazz ("D.M.S.O."), spoken word ("A Commercial") and psychedelia ("Cesspools In Eden"). The lyrical focus is more introspective and earnest ("Where Do Ya Draw The Line?"), with an anti-war, anti-violence ("Rambozo The Clown") bend, moving away from the violent imagery of their early records, while remaining as subversive as ever ("I Spy", "D.M.S.O."). In December, the band announced their split. Biafra went on to speak about his political beliefs on numerous television shows and he released a number of spoken-word albums. Ray, Flouride, and Peligro also went on to solo careers. Reforming of new band line-up In 2001, Ray, Peligro, and Flouride reformed the Dead Kennedys, with former Dr. Know singer Brandon Cruz replacing Biafra on vocals. The band played under the name "DK Kennedys" for a few concerts, but later reverted to "Dead Kennedys" permanently. They played across the continental United States, | world tours in 2013 and in 2014, the latter mostly in North American cities. In 2015 and 2016 they toured again, including South America, where they had not played since 2001. In 2017, East Bay Ray revealed that the band and Jello Biafra had been approached by the Punk-oriented music festival Riot Fest about a potential reunion. While Ray and the rest of the band expressed interest in the concept, Biafra refused. On April 26, 2019, the group released DK40, a live compilation album celebrating 40 years since the band formed. Conflicts between members Royalties lawsuit In the late 1990s, former band members discovered problems with the payment of royalties they had received from Alternative Tentacles. East Bay Ray, Klaus Flouride, and D. H. Peligro claimed that Jello Biafra had conspired to pay lower royalty rates. Although both sides agreed that the failure to pay these royalties was an accounting mistake, the other members were upset that Biafra failed to inform them of the mistake after he and his co-workers discovered it and additionally claimed he intended to use the money against them. A jury found Biafra and Alternative Tentacles "guilty of malice, oppression and fraud". Malice was defined for the jury as "conduct which is intended to cause injury or despicable conduct which is carried with a willful and conscious disregard for the rights of others". Biafra's appeal was denied; he had to pay the outstanding royalties and punitive damages, and was forced to hand over the rights to the majority of Dead Kennedys' back catalogue to the Decay Music partnership. The jury and judges also noted, in their words, that Biafra "lacked credibility" on the songwriting issue and found from evidence presented by both sides that the songwriting credits were due to the entire band. This dispute was hotly contested by all concerned who felt passionately for their cause, and the case caused minor waves within punk circles. Biafra claims that East Bay Ray had long expressed displeasure with Alternative Tentacles and with the amount of money he received from them, thus the original incentive for the discovery of the back payments. It was found out that Alternative Tentacles was paying Dead Kennedys less per CD than all the other bands, including Biafra himself, and not informing his other bandmates, which was the fraud. Biafra accused the band of wanting to license the famous Dead Kennedys song "Holiday in Cambodia" for use in a Levi's jeans commercial, which the band denied. However, an instrumental loop from "Holiday in Cambodia" was part of the 1981 movie "Neighbors," but wasn't included on the soundtrack. Biafra's former bandmates maintain that they sued because of Jello Biafra's deliberate withholding of money, though when pressed they have acknowledged that the payment was an accounting mistake, but insist that Biafra was wrong in failing to inform the band directly. Details about this issue remain scarce. The band also maintains that the Levi's story was completely fictitious and invented by Biafra to discredit them. Disputes over new commercial activities Matters were stirred up even further when the three bandmates invited Jello Biafra to "bury the hatchet" in the form of a band reunion. Jello Biafra felt it was unprofessional because no one contacted him directly. In addition, Biafra was disdainful of the reunion, and having long expressed his disdain for nostalgia and rock reunion/oldies tours in particular, argued that the whole affair was motivated by greed. Several DVDs, re-issues, and live albums have been released since the departure of Biafra most recently on Manifesto Records. According to Biafra, the live albums are "cash-ins" on Dead Kennedys' name and his music. Biafra also accused the releases of the new live material of having poor sound quality. Furthermore, he has stated he is not receiving any royalties from the sale of any Manifesto Records releases. Consequently, he has discouraged fans from buying any Dead Kennedy reissues. The other band members denied Biafra's accusations regarding the live releases, and have defended the mixes as an effort of hard work. Biafra dismissed the new group as "the world's greediest karaoke band." Nevertheless, in 2003, Klaus Flouride said of performances without the band's former frontman: "There hasn't been a show yet that people didn't really like." Biafra further criticized them for advertising shows using his own image taken from the original 1980s incarnation of the band, which he labeled as false advertising. He attacked the reformed Dead Kennedys in a song called "Those Dumb Punk Kids (Will Buy Anything)", which appears on his second collaboration with sludge metal band the Melvins, Sieg Howdy! Biafra told an audience at a speaking gig in Trenton, New Jersey, that the remaining Dead Kennedys have licensed their single "Too Drunk to Fuck" to be used in a rape scene in a Robert Rodriguez movie. The reference is to a lounge cover of the song, recorded by the band Nouvelle Vague, played during a scene in the Planet Terror segment of Grindhouse, although no rape takes place, and in fact the would-be rapist is killed by the would-be victim. The scene in Planet Terror has would-be rapist, "Rapist No. 1" (Quentin Tarantino) order one-legged stripper "Cherry Darlin" (Rose McGowan) to get up off the floor and dance. At this point Tarantino hits play on a cassette recorder and Nouvelle Vague's cover of "Too Drunk To Fuck" plays. Biafra, disapproving of the situation, later wrote, "This is their lowest point since Levi's... This goes against everything the Dead Kennedys stands for in spades... The terrified woman later 'wins' by killing Tarantino, but that excuse does not rescue this at all. I wrote every note of that song and this is not what it was meant for.... Some people will do anything for money. I can't help but think back to how prudish Klaus Flouride was when he objected to H.R. Giger's painting on the "Frankenchrist" (sic) poster, saying he couldn't bear to show it to his parents. I'd sure love to be a fly on the wall when he tries to explain putting a song in a rape scene for money to his teenage daughter... The deal was pushed through by a new business manager the other three hired." The reformed Dead Kennedys followed their court victory by releasing reissues of all Dead Kennedys albums (except Fresh Fruit for Rotting Vegetables, to which they did not have the rights until 2005), releasing several new archival concert DVDs, and licensing several songs to The Manchurian Candidate |
chromosome ends using the enzyme telomerase, as the enzymes that normally replicate DNA cannot copy the extreme 3′ ends of chromosomes. These specialized chromosome caps also help protect the DNA ends, and stop the DNA repair systems in the cell from treating them as damage to be corrected. In human cells, telomeres are usually lengths of single-stranded DNA containing several thousand repeats of a simple TTAGGG sequence. These guanine-rich sequences may stabilize chromosome ends by forming structures of stacked sets of four-base units, rather than the usual base pairs found in other DNA molecules. Here, four guanine bases, known as a guanine tetrad, form a flat plate. These flat four-base units then stack on top of each other to form a stable G-quadruplex structure. These structures are stabilized by hydrogen bonding between the edges of the bases and chelation of a metal ion in the centre of each four-base unit. Other structures can also be formed, with the central set of four bases coming from either a single strand folded around the bases, or several different parallel strands, each contributing one base to the central structure. In addition to these stacked structures, telomeres also form large loop structures called telomere loops, or T-loops. Here, the single-stranded DNA curls around in a long circle stabilized by telomere-binding proteins. At the very end of the T-loop, the single-stranded telomere DNA is held onto a region of double-stranded DNA by the telomere strand disrupting the double-helical DNA and base pairing to one of the two strands. This triple-stranded structure is called a displacement loop or D-loop. Branched DNA can form networks containing multiple branches. Branched DNA In DNA, fraying occurs when non-complementary regions exist at the end of an otherwise complementary double-strand of DNA. However, branched DNA can occur if a third strand of DNA is introduced and contains adjoining regions able to hybridize with the frayed regions of the pre-existing double-strand. Although the simplest example of branched DNA involves only three strands of DNA, complexes involving additional strands and multiple branches are also possible. Branched DNA can be used in nanotechnology to construct geometric shapes, see the section on uses in technology below. Artificial bases Several artificial nucleobases have been synthesized, and successfully incorporated in the eight-base DNA analogue named Hachimoji DNA. Dubbed S, B, P, and Z, these artificial bases are capable of bonding with each other in a predictable way (S–B and P–Z), maintain the double helix structure of DNA, and be transcribed to RNA. Their existence could be seen as an indication that there is nothing special about the four natural nucleobases that evolved on Earth. On the other hand, DNA is tightly related to RNA which does not only act as a transcript of DNA but also performs as moleular machines many tasks in cells. For this purpose it has to fold into a structure. It has been shown that to allow to create all possible structures at least four bases are required for the corresponding RNA, while a higher number is also possible but this would be against the natural Principle of least effort. Chemical modifications and altered DNA packaging Structure of cytosine with and without the 5-methyl group. Deamination converts 5-methylcytosine into thymine. Base modifications and DNA packaging The expression of genes is influenced by how the DNA is packaged in chromosomes, in a structure called chromatin. Base modifications can be involved in packaging, with regions that have low or no gene expression usually containing high levels of methylation of cytosine bases. DNA packaging and its influence on gene expression can also occur by covalent modifications of the histone protein core around which DNA is wrapped in the chromatin structure or else by remodeling carried out by chromatin remodeling complexes (see Chromatin remodeling). There is, further, crosstalk between DNA methylation and histone modification, so they can coordinately affect chromatin and gene expression. For one example, cytosine methylation produces 5-methylcytosine, which is important for X-inactivation of chromosomes. The average level of methylation varies between organisms—the worm Caenorhabditis elegans lacks cytosine methylation, while vertebrates have higher levels, with up to 1% of their DNA containing 5-methylcytosine. Despite the importance of 5-methylcytosine, it can deaminate to leave a thymine base, so methylated cytosines are particularly prone to mutations. Other base modifications include adenine methylation in bacteria, the presence of 5-hydroxymethylcytosine in the brain, and the glycosylation of uracil to produce the "J-base" in kinetoplastids. Damage DNA can be damaged by many sorts of mutagens, which change the DNA sequence. Mutagens include oxidizing agents, alkylating agents and also high-energy electromagnetic radiation such as ultraviolet light and X-rays. The type of DNA damage produced depends on the type of mutagen. For example, UV light can damage DNA by producing thymine dimers, which are cross-links between pyrimidine bases. On the other hand, oxidants such as free radicals or hydrogen peroxide produce multiple forms of damage, including base modifications, particularly of guanosine, and double-strand breaks. A typical human cell contains about 150,000 bases that have suffered oxidative damage. Of these oxidative lesions, the most dangerous are double-strand breaks, as these are difficult to repair and can produce point mutations, insertions, deletions from the DNA sequence, and chromosomal translocations. These mutations can cause cancer. Because of inherent limits in the DNA repair mechanisms, if humans lived long enough, they would all eventually develop cancer. DNA damages that are naturally occurring, due to normal cellular processes that produce reactive oxygen species, the hydrolytic activities of cellular water, etc., also occur frequently. Although most of these damages are repaired, in any cell some DNA damage may remain despite the action of repair processes. These remaining DNA damages accumulate with age in mammalian postmitotic tissues. This accumulation appears to be an important underlying cause of aging. Many mutagens fit into the space between two adjacent base pairs, this is called intercalation. Most intercalators are aromatic and planar molecules; examples include ethidium bromide, acridines, daunomycin, and doxorubicin. For an intercalator to fit between base pairs, the bases must separate, distorting the DNA strands by unwinding of the double helix. This inhibits both transcription and DNA replication, causing toxicity and mutations. As a result, DNA intercalators may be carcinogens, and in the case of thalidomide, a teratogen. Others such as benzo[a]pyrene diol epoxide and aflatoxin form DNA adducts that induce errors in replication. Nevertheless, due to their ability to inhibit DNA transcription and replication, other similar toxins are also used in chemotherapy to inhibit rapidly growing cancer cells. Biological functions DNA usually occurs as linear chromosomes in eukaryotes, and circular chromosomes in prokaryotes. The set of chromosomes in a cell makes up its genome; the human genome has approximately 3 billion base pairs of DNA arranged into 46 chromosomes. The information carried by DNA is held in the sequence of pieces of DNA called genes. Transmission of genetic information in genes is achieved via complementary base pairing. For example, in transcription, when a cell uses the information in a gene, the DNA sequence is copied into a complementary RNA sequence through the attraction between the DNA and the correct RNA nucleotides. Usually, this RNA copy is then used to make a matching protein sequence in a process called translation, which depends on the same interaction between RNA nucleotides. In alternative fashion, a cell may simply copy its genetic information in a process called DNA replication. The details of these functions are covered in other articles; here the focus is on the interactions between DNA and other molecules that mediate the function of the genome. Genes and genomes Genomic DNA is tightly and orderly packed in the process called DNA condensation, to fit the small available volumes of the cell. In eukaryotes, DNA is located in the cell nucleus, with small amounts in mitochondria and chloroplasts. In prokaryotes, the DNA is held within an irregularly shaped body in the cytoplasm called the nucleoid. The genetic information in a genome is held within genes, and the complete set of this information in an organism is called its genotype. A gene is a unit of heredity and is a region of DNA that influences a particular characteristic in an organism. Genes contain an open reading frame that can be transcribed, and regulatory sequences such as promoters and enhancers, which control transcription of the open reading frame. In many species, only a small fraction of the total sequence of the genome encodes protein. For example, only about 1.5% of the human genome consists of protein-coding exons, with over 50% of human DNA consisting of non-coding repetitive sequences. The reasons for the presence of so much noncoding DNA in eukaryotic genomes and the extraordinary differences in genome size, or C-value, among species, represent a long-standing puzzle known as the "C-value enigma". However, some DNA sequences that do not code protein may still encode functional non-coding RNA molecules, which are involved in the regulation of gene expression. Some noncoding DNA sequences play structural roles in chromosomes. Telomeres and centromeres typically contain few genes but are important for the function and stability of chromosomes. An abundant form of noncoding DNA in humans are pseudogenes, which are copies of genes that have been disabled by mutation. These sequences are usually just molecular fossils, although they can occasionally serve as raw genetic material for the creation of new genes through the process of gene duplication and divergence. Transcription and translation A gene is a sequence of DNA that contains genetic information and can influence the phenotype of an organism. Within a gene, the sequence of bases along a DNA strand defines a messenger RNA sequence, which then defines one or more protein sequences. The relationship between the nucleotide sequences of genes and the amino-acid sequences of proteins is determined by the rules of translation, known collectively as the genetic code. The genetic code consists of three-letter 'words' called codons formed from a sequence of three nucleotides (e.g. ACT, CAG, TTT). In transcription, the codons of a gene are copied into messenger RNA by RNA polymerase. This RNA copy is then decoded by a ribosome that reads the RNA sequence by base-pairing the messenger RNA to transfer RNA, which carries amino acids. Since there are 4 bases in 3-letter combinations, there are 64 possible codons (43 combinations). These encode the twenty standard amino acids, giving most amino acids more than one possible codon. There are also three 'stop' or 'nonsense' codons signifying the end of the coding region; these are the TAG, TAA, and TGA codons, (UAG, UAA, and UGA on the mRNA). Replication Cell division is essential for an organism to grow, but, when a cell divides, it must replicate the DNA in its genome so that the two daughter cells have the same genetic information as their parent. The double-stranded structure of DNA provides a simple mechanism for DNA replication. Here, the two strands are separated and then each strand's complementary DNA sequence is recreated by an enzyme called DNA polymerase. This enzyme makes the complementary strand by finding the correct base through complementary base pairing and bonding it onto the original strand. As DNA polymerases can only extend a DNA strand in a 5′ to 3′ direction, different mechanisms are used to copy the antiparallel strands of the double helix. In this way, the base on the old strand dictates which base appears on the new strand, and the cell ends up with a perfect copy of its DNA. Extracellular nucleic acids Naked extracellular DNA (eDNA), most of it released by cell death, is nearly ubiquitous in the environment. Its concentration in soil may be as high as 2 μg/L, and its concentration in natural aquatic environments may be as high at 88 μg/L. Various possible functions have been proposed for eDNA: it may be involved in horizontal gene transfer; it may provide nutrients; and it may act as a buffer to recruit or titrate ions or antibiotics. Extracellular DNA acts as a functional extracellular matrix component in the biofilms of several bacterial species. It may act as a recognition factor to regulate the attachment and dispersal of specific cell types in the biofilm; it may contribute to biofilm formation; and it may contribute to the biofilm's physical strength and resistance to biological stress. Cell-free fetal DNA is found in the blood of the mother, and can be sequenced to determine a great deal of information about the developing fetus. Under the name of environmental DNA eDNA has seen increased use in the natural sciences as a survey tool for ecology, monitoring the movements and presence of species in water, air, or on land, and assessing an area's biodiversity. Neutrophil extracellular traps Neutrophil extracellular traps (NETs) are networks of extracellular fibers, primarily composed of DNA, which allow neutrophils, a type of white blood cell, to kill extracellular pathogens while minimizing damage to the host cells. Interactions with proteins All the functions of DNA depend on interactions with proteins. These protein interactions can be non-specific, or the protein can bind specifically to a single DNA sequence. Enzymes can also bind to DNA and of these, the polymerases that copy the DNA base sequence in transcription and DNA replication are particularly important. DNA-binding proteins Structural proteins that bind DNA are well-understood examples of non-specific DNA-protein interactions. Within chromosomes, DNA is held in complexes with structural proteins. These proteins organize the DNA into a compact structure called chromatin. In eukaryotes, this structure involves DNA binding to a complex of small basic proteins called histones, while in prokaryotes multiple types of proteins are involved. The histones form a disk-shaped complex called a nucleosome, which contains two complete turns of double-stranded DNA wrapped around its surface. These non-specific interactions are formed through basic residues in the histones, making ionic bonds to the acidic sugar-phosphate backbone of the DNA, and are thus largely independent of the base sequence. Chemical modifications of these basic amino acid residues include methylation, phosphorylation, and acetylation. These chemical changes alter the strength of the interaction between the DNA and the histones, making the DNA more or less accessible to transcription factors and changing the rate of transcription. Other non-specific DNA-binding proteins in chromatin include the high-mobility group proteins, which bind to bent or distorted DNA. These proteins are important in bending arrays of nucleosomes and arranging them into the larger structures that make up chromosomes. A distinct group of DNA-binding proteins is the DNA-binding proteins that specifically bind single-stranded DNA. In humans, replication protein | conformations of DNA within the cell (see below), but the major and minor grooves are always named to reflect the differences in width that would be seen if the DNA was twisted back into the ordinary B form. Base pairing In a DNA double helix, each type of nucleobase on one strand bonds with just one type of nucleobase on the other strand. This is called complementary base pairing. Purines form hydrogen bonds to pyrimidines, with adenine bonding only to thymine in two hydrogen bonds, and cytosine bonding only to guanine in three hydrogen bonds. This arrangement of two nucleotides binding together across the double helix (from six-carbon ring to six-carbon ring) is called a Watson-Crick base pair. DNA with high GC-content is more stable than DNA with low -content. A Hoogsteen base pair (hydrogen bonding the 6-carbon ring to the 5-carbon ring) is a rare variation of base-pairing. As hydrogen bonds are not covalent, they can be broken and rejoined relatively easily. The two strands of DNA in a double helix can thus be pulled apart like a zipper, either by a mechanical force or high temperature. As a result of this base pair complementarity, all the information in the double-stranded sequence of a DNA helix is duplicated on each strand, which is vital in DNA replication. This reversible and specific interaction between complementary base pairs is critical for all the functions of DNA in organisms. Top, a base pair with three hydrogen bonds. Bottom, an base pair with two hydrogen bonds. Non-covalent hydrogen bonds between the pairs are shown as dashed lines. ssDNA vs. dsDNA As noted above, most DNA molecules are actually two polymer strands, bound together in a helical fashion by noncovalent bonds; this double-stranded (dsDNA) structure is maintained largely by the intrastrand base stacking interactions, which are strongest for stacks. The two strands can come apart—a process known as melting—to form two single-stranded DNA (ssDNA) molecules. Melting occurs at high temperature, low salt and high pH (low pH also melts DNA, but since DNA is unstable due to acid depurination, low pH is rarely used). The stability of the dsDNA form depends not only on the -content (% basepairs) but also on sequence (since stacking is sequence specific) and also length (longer molecules are more stable). The stability can be measured in various ways; a common way is the their melting temperature (also called Tm value), which is the temperature at which 50% of the double-strand molecules are converted to single-strand molecules; melting temperature is dependent on ionic strength and the concentration of DNA. As a result, it is both the percentage of base pairs and the overall length of a DNA double helix that determines the strength of the association between the two strands of DNA. Long DNA helices with a high -content have more strongly interacting strands, while short helices with high content have more weakly interacting strands. In biology, parts of the DNA double helix that need to separate easily, such as the Pribnow box in some promoters, tend to have a high content, making the strands easier to pull apart. In the laboratory, the strength of this interaction can be measured by finding the melting temperature Tm necessary to break half of the hydrogen bonds. When all the base pairs in a DNA double helix melt, the strands separate and exist in solution as two entirely independent molecules. These single-stranded DNA molecules have no single common shape, but some conformations are more stable than others. Sense and antisense A DNA sequence is called a "sense" sequence if it is the same as that of a messenger RNA copy that is translated into protein. The sequence on the opposite strand is called the "antisense" sequence. Both sense and antisense sequences can exist on different parts of the same strand of DNA (i.e. both strands can contain both sense and antisense sequences). In both prokaryotes and eukaryotes, antisense RNA sequences are produced, but the functions of these RNAs are not entirely clear. One proposal is that antisense RNAs are involved in regulating gene expression through RNA-RNA base pairing. A few DNA sequences in prokaryotes and eukaryotes, and more in plasmids and viruses, blur the distinction between sense and antisense strands by having overlapping genes. In these cases, some DNA sequences do double duty, encoding one protein when read along one strand, and a second protein when read in the opposite direction along the other strand. In bacteria, this overlap may be involved in the regulation of gene transcription, while in viruses, overlapping genes increase the amount of information that can be encoded within the small viral genome. Supercoiling DNA can be twisted like a rope in a process called DNA supercoiling. With DNA in its "relaxed" state, a strand usually circles the axis of the double helix once every 10.4 base pairs, but if the DNA is twisted the strands become more tightly or more loosely wound. If the DNA is twisted in the direction of the helix, this is positive supercoiling, and the bases are held more tightly together. If they are twisted in the opposite direction, this is negative supercoiling, and the bases come apart more easily. In nature, most DNA has slight negative supercoiling that is introduced by enzymes called topoisomerases. These enzymes are also needed to relieve the twisting stresses introduced into DNA strands during processes such as transcription and DNA replication. Alternative DNA structures DNA exists in many possible conformations that include A-DNA, B-DNA, and Z-DNA forms, although, only B-DNA and Z-DNA have been directly observed in functional organisms. The conformation that DNA adopts depends on the hydration level, DNA sequence, the amount and direction of supercoiling, chemical modifications of the bases, the type and concentration of metal ions, and the presence of polyamines in solution. The first published reports of A-DNA X-ray diffraction patterns—and also B-DNA—used analyses based on Patterson functions that provided only a limited amount of structural information for oriented fibers of DNA. An alternative analysis was proposed by Wilkins et al. in 1953 for the in vivo B-DNA X-ray diffraction-scattering patterns of highly hydrated DNA fibers in terms of squares of Bessel functions. In the same journal, James Watson and Francis Crick presented their molecular modeling analysis of the DNA X-ray diffraction patterns to suggest that the structure was a double helix. Although the B-DNA form is most common under the conditions found in cells, it is not a well-defined conformation but a family of related DNA conformations that occur at the high hydration levels present in cells. Their corresponding X-ray diffraction and scattering patterns are characteristic of molecular paracrystals with a significant degree of disorder. Compared to B-DNA, the A-DNA form is a wider right-handed spiral, with a shallow, wide minor groove and a narrower, deeper major groove. The A form occurs under non-physiological conditions in partly dehydrated samples of DNA, while in the cell it may be produced in hybrid pairings of DNA and RNA strands, and in enzyme-DNA complexes. Segments of DNA where the bases have been chemically modified by methylation may undergo a larger change in conformation and adopt the Z form. Here, the strands turn about the helical axis in a left-handed spiral, the opposite of the more common B form. These unusual structures can be recognized by specific Z-DNA binding proteins and may be involved in the regulation of transcription. Alternative DNA chemistry For many years, exobiologists have proposed the existence of a shadow biosphere, a postulated microbial biosphere of Earth that uses radically different biochemical and molecular processes than currently known life. One of the proposals was the existence of lifeforms that use arsenic instead of phosphorus in DNA. A report in 2010 of the possibility in the bacterium GFAJ-1 was announced, though the research was disputed, and evidence suggests the bacterium actively prevents the incorporation of arsenic into the DNA backbone and other biomolecules. Quadruplex structures At the ends of the linear chromosomes are specialized regions of DNA called telomeres. The main function of these regions is to allow the cell to replicate chromosome ends using the enzyme telomerase, as the enzymes that normally replicate DNA cannot copy the extreme 3′ ends of chromosomes. These specialized chromosome caps also help protect the DNA ends, and stop the DNA repair systems in the cell from treating them as damage to be corrected. In human cells, telomeres are usually lengths of single-stranded DNA containing several thousand repeats of a simple TTAGGG sequence. These guanine-rich sequences may stabilize chromosome ends by forming structures of stacked sets of four-base units, rather than the usual base pairs found in other DNA molecules. Here, four guanine bases, known as a guanine tetrad, form a flat plate. These flat four-base units then stack on top of each other to form a stable G-quadruplex structure. These structures are stabilized by hydrogen bonding between the edges of the bases and chelation of a metal ion in the centre of each four-base unit. Other structures can also be formed, with the central set of four bases coming from either a single strand folded around the bases, or several different parallel strands, each contributing one base to the central structure. In addition to these stacked structures, telomeres also form large loop structures called telomere loops, or T-loops. Here, the single-stranded DNA curls around in a long circle stabilized by telomere-binding proteins. At the very end of the T-loop, the single-stranded telomere DNA is held onto a region of double-stranded DNA by the telomere strand disrupting the double-helical DNA and base pairing to one of the two strands. This triple-stranded structure is called a displacement loop or D-loop. Branched DNA can form networks containing multiple branches. Branched DNA In DNA, fraying occurs when non-complementary regions exist at the end of an otherwise complementary double-strand of DNA. However, branched DNA can occur if a third strand of DNA is introduced and contains adjoining regions able to hybridize with the frayed regions of the pre-existing double-strand. Although the simplest example of branched DNA involves only three strands of DNA, complexes involving additional strands and multiple branches are also possible. Branched DNA can be used in nanotechnology to construct geometric shapes, see the section on uses in technology below. Artificial bases Several artificial nucleobases have been synthesized, and successfully incorporated in the eight-base DNA analogue named Hachimoji DNA. Dubbed S, B, P, and Z, these artificial bases are capable of bonding with each other in a predictable way (S–B and P–Z), maintain the double helix structure of DNA, and be transcribed to RNA. Their existence could be seen as an indication that there is nothing special about the four natural nucleobases that evolved on Earth. On the other hand, DNA is tightly related to RNA which does not only act as a transcript of DNA but also performs as moleular machines many tasks in cells. For this purpose it has to fold into a structure. It has been shown that to allow to create all possible structures at least four bases are required for the corresponding RNA, while a higher number is also possible but this would be against the natural Principle of least effort. Chemical modifications and altered DNA packaging Structure of cytosine with and without the 5-methyl group. Deamination converts 5-methylcytosine into thymine. Base modifications and DNA packaging The expression of genes is influenced by how the DNA is packaged in chromosomes, in a structure called chromatin. Base modifications can be involved in packaging, with regions that have low or no gene expression usually containing high levels of methylation of cytosine bases. DNA packaging and its influence on gene expression can also occur by covalent modifications of the histone protein core around which DNA is wrapped in the chromatin structure or else by remodeling carried out by chromatin remodeling complexes (see Chromatin remodeling). There is, further, crosstalk between DNA methylation and histone modification, so they can coordinately affect chromatin and gene expression. For one example, cytosine methylation produces 5-methylcytosine, which is important for X-inactivation of chromosomes. The average level of methylation varies between organisms—the worm Caenorhabditis elegans lacks cytosine methylation, while vertebrates have higher levels, with up to 1% of their DNA containing 5-methylcytosine. Despite the importance of 5-methylcytosine, it can deaminate to leave a thymine base, so methylated cytosines are particularly prone to mutations. Other base modifications include adenine methylation in bacteria, the presence of 5-hydroxymethylcytosine in the brain, and the glycosylation of uracil to produce the "J-base" in kinetoplastids. Damage DNA can be damaged by many sorts of mutagens, which change the DNA sequence. Mutagens include oxidizing agents, alkylating agents and also high-energy electromagnetic radiation such as ultraviolet light and X-rays. The type of DNA damage produced depends on the type of mutagen. For example, UV light can damage DNA by producing thymine dimers, which are cross-links between pyrimidine bases. On the other hand, oxidants such as free radicals or hydrogen peroxide produce multiple forms of damage, including base modifications, particularly of guanosine, and double-strand breaks. A typical human cell contains about 150,000 bases that have suffered oxidative damage. Of these oxidative lesions, the most dangerous are double-strand breaks, as these are difficult to repair and can produce point mutations, insertions, deletions from the DNA sequence, and chromosomal translocations. These mutations can cause cancer. Because of inherent limits in the DNA repair mechanisms, if humans lived long enough, they would all eventually develop cancer. DNA damages that are naturally occurring, due to normal cellular processes that produce reactive oxygen species, the hydrolytic activities of cellular water, etc., also occur frequently. Although most of these damages are repaired, in any cell some DNA damage may remain despite the action of repair processes. These remaining DNA damages accumulate with age in mammalian postmitotic tissues. This accumulation appears to be an important underlying cause of aging. Many mutagens fit into the space between two adjacent base pairs, this is called intercalation. Most intercalators are aromatic and planar molecules; examples include ethidium bromide, acridines, daunomycin, and doxorubicin. For an intercalator to fit between base pairs, the bases must separate, distorting the DNA strands by unwinding of the double helix. This inhibits both transcription and DNA replication, causing toxicity and mutations. As a result, DNA intercalators may be carcinogens, and in the case of thalidomide, a teratogen. Others such as benzo[a]pyrene diol epoxide and aflatoxin form DNA adducts that induce errors in replication. Nevertheless, due to their ability to inhibit DNA transcription and replication, other similar toxins are also used in chemotherapy to inhibit rapidly growing cancer cells. Biological functions DNA usually occurs as linear chromosomes in eukaryotes, and circular chromosomes in prokaryotes. The set of chromosomes in a cell makes up its genome; the human genome has approximately 3 billion base pairs of DNA arranged into 46 chromosomes. The information carried by DNA is held in the sequence of pieces of DNA called genes. Transmission of genetic information in genes is achieved via complementary base pairing. For example, in transcription, when a cell uses the information in a gene, the DNA sequence is copied into a complementary RNA sequence through the attraction between the DNA and the correct RNA nucleotides. Usually, this RNA copy is then used to make a matching protein sequence in a process called translation, which depends on the same interaction between RNA nucleotides. In alternative fashion, a cell may simply copy its genetic information in a process called DNA replication. The details of these functions are covered in other articles; here the focus is on the interactions between DNA and other molecules that mediate the function of the genome. Genes and genomes Genomic DNA is tightly and orderly packed in the process called DNA condensation, to fit the small available volumes of the cell. In eukaryotes, DNA is located in the cell nucleus, with small amounts in mitochondria and chloroplasts. In prokaryotes, the DNA is held within an irregularly shaped body in the cytoplasm called the nucleoid. The genetic information in a genome is held within genes, and the complete set of this information in an organism is called its genotype. A gene is a unit of heredity and is a region of DNA that influences a particular characteristic in an organism. Genes contain an open reading frame that can be transcribed, and regulatory sequences such as promoters and enhancers, which control transcription of the open reading frame. In many species, only a small fraction of the total sequence of the genome encodes protein. For example, only about 1.5% of the human genome consists of protein-coding exons, with over 50% of human DNA consisting of non-coding repetitive sequences. The reasons for the presence of so much noncoding DNA in eukaryotic genomes and the extraordinary differences in genome size, or C-value, among species, represent a long-standing puzzle known as the "C-value enigma". However, some DNA sequences that do not code protein may still encode functional non-coding RNA molecules, which are involved in the regulation of gene expression. Some noncoding DNA sequences play structural roles in chromosomes. Telomeres and centromeres typically contain few genes but are important for the function and stability of chromosomes. An abundant form of noncoding DNA in humans are pseudogenes, which are copies of genes that have been disabled by mutation. These sequences are usually just molecular fossils, although they can occasionally serve as raw genetic material for the creation of new genes through the process of gene duplication and divergence. Transcription and translation A gene is a sequence of DNA that contains genetic information and can influence the phenotype of an organism. Within a gene, the sequence of bases along a DNA strand defines a messenger RNA sequence, which then defines one or more protein sequences. The relationship between the nucleotide sequences of genes and the amino-acid sequences of proteins is determined by the rules of translation, known collectively as the genetic code. The genetic code consists of three-letter 'words' called codons formed from a sequence of three nucleotides (e.g. ACT, CAG, TTT). In transcription, the codons of a gene are copied into messenger RNA by RNA polymerase. This RNA copy is then decoded by a ribosome that reads the RNA sequence by base-pairing the messenger RNA to transfer RNA, which carries amino acids. Since there are 4 bases in 3-letter combinations, there are 64 possible codons (43 combinations). These encode the twenty standard amino acids, giving most amino acids more than one possible codon. There are also three 'stop' or 'nonsense' codons signifying the end of the coding region; these are the TAG, TAA, and TGA codons, (UAG, UAA, and UGA on the mRNA).

Kennedy Sr. and Rose Elizabeth Fitzgerald were the parents of nine children: Joseph Jr., John, Rose Marie (called Rosemary), Kathleen, Eunice, Patricia, Robert, Jean, and Edward (called Ted). John served as the 35th president of the United States, while Robert and Ted both became prominent senators. Every Kennedy elected to public office has served as a Democrat, while other members of the family have worked for the Democratic Party or held Cabinet posts in Democratic administrations. Many have attended Harvard University, and the family has contributed greatly to that university's John F. Kennedy School of Government. Joseph Sr. expected his eldest son, Joseph Jr., to go into politics and to ultimately be elected president. Joseph Jr. was elected as a delegate to the 1940 Democratic National Convention, and enlisted in the Navy after the U.S. entered World War II. He was killed in 1944 when the bomber he was piloting exploded in flight. Joseph Sr.'s desire to see the family involved in politics and government then focused on John, who had considered a career as a journalist, having authored a book and done some reporting for Hearst Newspapers. After returning from Navy service, John served in the U.S. House of Representatives representing Massachusetts's 11th congressional district from 1947 to 1953, and then as U.S. Senator from Massachusetts until his election as President in 1960.

inevitably led to tyranny. Democracy was therefore highly fragile and rare historically, as it could only survive in small political units, which due to their size were vulnerable to conquest by larger political units. Montesquieu famously said, "if a republic is small, it is destroyed by an outside force; if it is large, it is destroyed by an internal vice." Rousseau asserted, "It is, therefore the natural property of small states to be governed as a republic, of middling ones to be subject to a monarch, and of large empires to be swayed by a despotic prince." Contemporary theory Among modern political theorists, there are three contending conceptions of democracy: aggregative democracy, deliberative democracy, and radical democracy. Aggregative The theory of aggregative democracy claims that the aim of the democratic processes is to solicit citizens' preferences and aggregate them together to determine what social policies society should adopt. Therefore, proponents of this view hold that democratic participation should primarily focus on voting, where the policy with the most votes gets implemented. Different variants of aggregative democracy exist. Under minimalism, democracy is a system of government in which citizens have given teams of political leaders the right to rule in periodic elections. According to this minimalist conception, citizens cannot and should not "rule" because, for example, on most issues, most of the time, they have no clear views or their views are not well-founded. Joseph Schumpeter articulated this view most famously in his book Capitalism, Socialism, and Democracy. Contemporary proponents of minimalism include William H. Riker, Adam Przeworski, Richard Posner. According to the theory of direct democracy, on the other hand, citizens should vote directly, not through their representatives, on legislative proposals. Proponents of direct democracy offer varied reasons to support this view. Political activity can be valuable in itself, it socialises and educates citizens, and popular participation can check powerful elites. Most importantly, citizens do not rule themselves unless they directly decide laws and policies. Governments will tend to produce laws and policies that are close to the views of the median voter—with half to their left and the other half to their right. This is not a desirable outcome as it represents the action of self-interested and somewhat unaccountable political elites competing for votes. Anthony Downs suggests that ideological political parties are necessary to act as a mediating broker between individual and governments. Downs laid out this view in his 1957 book An Economic Theory of Democracy. Robert A. Dahl argues that the fundamental democratic principle is that, when it comes to binding collective decisions, each person in a political community is entitled to have his/her interests be given equal consideration (not necessarily that all people are equally satisfied by the collective decision). He uses the term polyarchy to refer to societies in which there exists a certain set of institutions and procedures which are perceived as leading to such democracy. First and foremost among these institutions is the regular occurrence of free and open elections which are used to select representatives who then manage all or most of the public policy of the society. However, these polyarchic procedures may not create a full democracy if, for example, poverty prevents political participation. Similarly, Ronald Dworkin argues that "democracy is a substantive, not a merely procedural, ideal." DeliberativeDeliberative democracy is based on the notion that democracy is government by deliberation. Unlike aggregative democracy, deliberative democracy holds that, for a democratic decision to be legitimate, it must be preceded by authentic deliberation, not merely the aggregation of preferences that occurs in voting. Authentic deliberation is deliberation among decision-makers that is free from distortions of unequal political power, such as power a decision-maker obtained through economic wealth or the support of interest groups.Joshua Cohen, "Deliberation and Democratic Legitimacy" in Essays on Reason and Politics: Deliberative Democracy Ed. James Bohman and William Rehg (The MIT Press: Cambridge) 1997, 72–73. If the decision-makers cannot reach consensus after authentically deliberating on a proposal, then they vote on the proposal using a form of majority rule. Citizens assemblies are considered by many scholars as practical examples of deliberative democracy, with a recent OECD report identifying citizens assemblies as an increasingly popular mechanism to involve citizens in governmental decision-making. RadicalRadical democracy is based on the idea that there are hierarchical and oppressive power relations that exist in society. Democracy's role is to make visible and challenge those relations by allowing for difference, dissent and antagonisms in decision-making processes. Measurement of democracy Indices ranking degree of democracy Ranking of the degree of democracy are published by several organisations according to their own various definitions of the term and relying on different types of data: The V-Dem Institute's Varieties of Democracy Report is published each year since 2014 by the Swedish research institute V-Dem.Nazifa Alizada, Rowan Cole, Lisa Gastaldi, Sandra Grahn, Sebastian Hellmeier, Palina Kolvani, Jean Lachapelle, Anna Lührmann, Seraphine F.

The Democracy Index, published by the UK-based Economist Intelligence Unit, is an assessment of countries' democracy. Countries are rated to be either Full Democracies, Flawed Democracies, Hybrid Regimes, or Authoritarian regimes. Full democracies, flawed democracies, and hybrid regimes are considered to be democracies, and the authoritarian states are considered to be dictatorial or oligarchic. The index is based on 60 indicators grouped in five different categories. The U.S.-based Polity data series is a widely used data series in political science research. It contains coded annual information on regime authority characteristics and transitions for all independent states with greater than 500,000 total population and covers the years 1800–2006. Polity's conclusions about a state's level of democracy are based on an evaluation of that state's elections for competitiveness, openness and level of participation. The Polity work is sponsored by the Political Instability Task Force (PITF) which is funded by the U.S. Central Intelligence Agency. However, the views expressed in the reports are the authors' alone and do not represent the views of the US Government. MaxRange, a dataset defining level of democracy and institutional structure(regime-type) on a 100-graded scale where every value represents a unique regime type. Values are sorted from 1–100 based on level of democracy and political accountability. MaxRange defines the value corresponding to all states and every month from 1789 to 2015 and updating. MaxRange is created and developed by Max Range, and is now associated with the university of Halmstad, Sweden. Other indices measuring freedom and human rights include degree of democracy as an element. Some of these include the Freedom in the World ranking, the Worldwide Press Freedom Index, the Index of Freedom in the World, and the CIRI Human Rights Data Project. Difficulties in measuring democracy Because democracy is an overarching concept that includes the functioning of diverse institutions which are not easy to measure, strong limitations exist in quantifying and econometrically measuring the potential effects of democracy or its relationship with other phenomena—whether inequality, poverty, education etc. Given the constraints in acquiring reliable data with within-country variation on aspects of democracy, academics have largely studied cross-country variations. Yet variations between democratic institutions are very large across countries which constrains meaningful comparisons using statistical approaches. Since democracy is typically measured aggregately as a macro variable using a single observation for each country and each year, studying democracy faces a range of econometric constraints and is limited to basic correlations. Cross-country comparison of a composite, comprehensive and qualitative concept like democracy may thus not always be, for many purposes, methodologically rigorous or useful. Dieter Fuchs and Edeltraud Roller suggest that, in order to truly measure the quality of democracy, objective measurements need to be complemented by "subjective measurements based on the perspective of citizens". Similarly, Quinton Mayne and Brigitte Geißel also defend that the quality of democracy does not depend exclusively on the performance of institutions, but also on the citizens' own dispositions and commitment. Types of governmental democracies Democracy has taken a number of forms, both in theory and practice. Some varieties of democracy provide better representation and more freedom for their citizens than others.The Judge in a Democracy, Princeton University Press, 2006, p. 26, , Google Books link However, if any democracy is not structured to prohibit the government from excluding the people from the legislative process, or any branch of government from altering the separation of powers in its favour, then a branch of the system can accumulate too much power and destroy the democracy.T.R. Williamson, Problems in American Democracy, Kessinger Publishing, 2004, p. 36, , Google Books link The following kinds of democracy are not exclusive of one another: many specify details of aspects that are independent of one another and can co-exist in a single system. Basic forms Several variants of democracy exist, but there are two basic forms, both of which concern how the whole body of all eligible citizens executes its will. One form of democracy is direct democracy, in which all eligible citizens have active participation in the political decision making, for example voting on policy initiatives directly. In most modern democracies, the whole body of eligible citizens remain the sovereign power but political power is exercised indirectly through elected representatives; this is called a representative democracy. Direct Direct democracy is a political system where the citizens participate in the decision-making personally, contrary to relying on intermediaries or representatives. A direct democracy gives the voting population the power to: Change constitutional laws, Put forth initiatives, referendums and suggestions for laws, Give binding orders to elective officials, such as revoking them before the end of their elected term or initiating a lawsuit for breaking a campaign promise. Within modern-day representative governments, certain electoral tools like referendums, citizens' initiatives and recall elections are referred to as forms of direct democracy. However, some advocates of direct democracy argue for local assemblies of face-to-face discussion. Direct democracy as a government system currently exists in the Swiss cantons of Appenzell Innerrhoden and Glarus, the Rebel Zapatista Autonomous Municipalities, communities affiliated with the CIPO-RFM, the Bolivian city councils of FEJUVE, and Kurdish cantons of Rojava. Lot system The use of a lot system, a characteristic of Athenian democracy, is a feature of some versions of direct democracies. In this system, important governmental and administrative tasks are performed by citizens picked from a lottery. Representative Representative democracy involves the election of government officials by the people being represented. If the head of state is also democratically elected then it is called a democratic republic. The most common mechanisms involve election of the candidate with a majority or a plurality of the votes. Most western countries have representative systems. Representatives may be elected or become diplomatic representatives by a particular district (or constituency), or represent the entire electorate through proportional systems, with some using a combination of the two. Some representative democracies also incorporate elements of direct democracy, such as referendums. A characteristic of representative democracy is that while the representatives are elected by the people to act in the people's interest, they retain the freedom to exercise their own judgement as how best to do so. Such reasons have driven criticism upon representative democracy, pointing out the contradictions of representation mechanisms with democracy Parliamentary Parliamentary democracy is a representative democracy where government is appointed by or can be dismissed by, representatives as opposed to a "presidential rule" wherein the president is both head of state and the head of government and is elected by the voters. Under a parliamentary democracy, government is exercised by delegation to an executive ministry and subject to ongoing review, checks and balances by the legislative parliament elected by the people.Kuykendall, Ralph, Hawaii: A History. New York: Prentice Hall, 1948.Taussig, Capt. J.K., "Experiences during the Boxer Rebellion," in Quarterdeck and Fo'c'sle. Chicago: Rand McNally & Company, 1963 Parliamentary systems have the right to dismiss a Prime Minister at any point in time that they feel he or she is not doing their job to the expectations of the legislature. This is done through a Vote of No Confidence where the legislature decides whether or not to remove the Prime Minister from office by a majority support for his or her dismissal. In some countries, the Prime Minister can also call an election whenever he or she so chooses, and typically the Prime Minister will hold an election when he or she knows that they are in good favour with the public as to get re-elected. In other parliamentary democracies, extra elections are virtually never held, a minority government being preferred until the next ordinary elections. An important feature of the parliamentary democracy is the concept of the "loyal opposition". The essence of the concept is that the second largest political party (or coalition) opposes the governing party (or coalition), while still remaining loyal to the state and its democratic principles. Presidential Presidential Democracy is a system where the public elects the president by election. The president serves as both the head of state and head of government controlling most of the executive powers. The president serves for a specific term and cannot exceed that amount of time. Elections typically have a fixed date and aren't easily changed. The president has direct control over the cabinet, specifically appointing the cabinet members. The president cannot be easily removed from office by the legislature, but he or she cannot remove members of the legislative branch any more easily. This provides some measure of separation of powers. In consequence, however, the president and the legislature may end up in the control of separate parties, allowing one to block the other and thereby interfere with the orderly operation of the state. This may be the reason why presidential democracy is not very common outside the Americas, Africa, and Central and Southeast Asia. A semi-presidential system is a system of democracy in which the government includes both a prime minister and a president. The particular powers held by the prime minister and president vary by country. Hybrid or semi-direct Some modern democracies that are predominantly representative in nature also heavily rely upon forms of political action that are directly democratic. These democracies, which combine elements of representative democracy and direct democracy, are termed hybrid democracies, semi-direct democracies or participatory democracies. Examples include Switzerland and some U.S. states, where frequent use is made of referendums and initiatives. The Swiss confederation is a semi-direct democracy. At the federal level, citizens can propose changes to the constitution (federal popular initiative) or ask for a referendum to be held on any law voted by the parliament. Between January 1995 and June 2005, Swiss citizens voted 31 times, to answer 103 questions (during the same period, French citizens participated in only two referendums). Although in the past 120 years less than 250 initiatives have been put to referendum. The populace has been conservative, approving only about 10% of the initiatives put before them; in addition, they have often opted for a version of the initiative rewritten by government. Examples include the extensive use of referendums in the US state of California, which is a state that has more than 20 million voters. In New England, Town meetings are often used, especially in rural areas, to manage local government. This creates a hybrid form of government, with a local direct democracy and a representative state government. For example, most Vermont towns hold annual town meetings in March in which town officers are elected, budgets for the town and schools are voted on, and citizens have the opportunity to speak and be heard on political matters. Variants Constitutional monarchy Many countries such as the United Kingdom, Spain, the Netherlands, Belgium, Scandinavian countries, Thailand, Japan and Bhutan turned powerful monarchs into constitutional monarchs with limited or, often gradually, merely symbolic roles. For example, in the predecessor states to the United Kingdom, constitutional monarchy began to emerge and has continued uninterrupted since the Glorious Revolution of 1688 and passage of the Bill of Rights 1689. Strongly limited constitutional monarchies, such as the United Kingdom, have been referred to as crowned republics by writers such as H. G. Wells. In other countries, the monarchy was abolished along with the aristocratic system (as in France, China, Russia, Germany, Austria, Hungary, Italy, Greece and Egypt). An elected person, with or without significant powers, became the head of state in these countries. Elite upper houses of legislatures, which often had lifetime or hereditary tenure, were common in many states. Over time, these either had their powers limited (as with the British House of Lords) or else became elective and remained powerful (as with the Australian Senate). Republic The term republic has many different meanings, but today often refers to a representative democracy with an elected head of state, such as a president, serving for a limited term, in contrast to states with a hereditary monarch as a head of state, even if these states also are representative democracies with an elected or appointed head of government such as a prime minister. The Founding Fathers of the United States rarely praised and often criticised democracy, which in their view often came without the protection of a constitution enshrining inalienable rights; James Madison argued, especially in The Federalist No. 10, that what distinguished a direct democracy from a republic was that the former became weaker as it got larger and suffered more violently from the effects of faction, whereas a republic could get stronger as it got larger and combats faction by its very structure. Professors Richard Ellis of Willamette University and Michael Nelson of Rhodes College argue that much constitutional thought, from Madison to Lincoln and beyond, has focused on "the problem of majority tyranny." They conclude, "The principles of republican government embedded in the Constitution represent an effort by the framers to ensure that the inalienable rights of life, liberty, and the pursuit of happiness would not be trampled by majorities." What was critical to American values, John Adams insisted, was that the government be "bound by fixed laws, which the people have a voice in making, and a right to defend." As Benjamin Franklin was exiting after writing the U.S. constitution, Elizabeth Willing Powel asked him "Well, Doctor, what have we got—a republic or a monarchy?". He replied "A republic—if you can keep it." Liberal democracy A liberal democracy is a representative democracy in which the ability of the elected representatives to exercise decision-making power is subject to the rule of law, and moderated by a constitution or laws that emphasise the protection of the rights and freedoms of individuals, and which places constraints on the leaders and on the extent to which the will of the majority can be exercised against the rights of minorities (see civil liberties). In a liberal democracy, it is possible for some large-scale decisions to emerge from the many individual decisions that citizens are free to make. In other words, citizens can "vote with their feet" or "vote with their dollars", resulting in significant informal government-by-the-masses that exercises many "powers" associated with formal government elsewhere. Socialist Socialist thought has several different views on democracy. Social democracy, democratic socialism, and the dictatorship of the proletariat (usually exercised through Soviet democracy) are some examples. Many democratic socialists and social democrats believe in a form of participatory, industrial, economic and/or workplace democracy combined with a representative democracy. Within Marxist orthodoxy there is a hostility to what is commonly called "liberal democracy", which is simply referred to as parliamentary democracy because of its often centralised nature. Because of orthodox Marxists' desire to eliminate the political elitism they see in capitalism, Marxists, Leninists and Trotskyists believe in direct democracy implemented through a system of communes (which are sometimes called soviets). This system ultimately manifests itself as council democracy and begins with workplace democracy. Anarchist Anarchists are split in this domain, depending on whether they believe that a majority-rule is tyrannic or not. To many anarchists, the only form of democracy considered acceptable is direct democracy. Pierre-Joseph Proudhon argued that the only acceptable form of direct democracy is one in which it is recognised that majority decisions are not binding on the minority, even when unanimous. However, anarcho-communist Murray Bookchin criticised individualist anarchists for opposing democracy, and says "majority rule" is consistent with anarchism. Some anarcho-communists oppose the majoritarian nature of direct democracy, feeling that it can impede individual liberty and opt-in favour of a non-majoritarian form of consensus democracy, similar to Proudhon's position on direct democracy. Henry David Thoreau, who did not self-identify as an anarchist but argued for "a better government" and is cited as an inspiration by some anarchists, argued that people should not be in the position of ruling others or being ruled when there is no consent. Sortition Sometimes called "democracy without elections", sortition chooses decision makers via a random process. The intention is that those chosen will be representative of the opinions and interests of the people at large, and be more fair and impartial than an elected official. The technique was in widespread use in Athenian Democracy and Renaissance Florence and is still used in modern jury selection. Consociational A consociational democracy allows for simultaneous majority votes in two or more ethno-religious constituencies, and policies are enacted only if they gain majority support from both or all of them. Consensus democracy A consensus democracy, in contrast, would not be dichotomous. Instead, decisions would be based on a multi-option approach, and policies would be enacted if they gained sufficient support, either in a purely verbal agreement or via a consensus vote—a multi-option preference vote. If the threshold of support were at a sufficiently high level, minorities would be as it were protected automatically. Furthermore, any voting would be ethno-colour blind. Supranational Qualified majority voting is designed by the Treaty of Rome to be the principal method of reaching decisions in the European Council of Ministers. This system allocates votes to member states in part according to their population, but heavily weighted in favour of the smaller states. This might be seen as a form of representative democracy, but representatives to the Council might be appointed rather than directly elected. Inclusive Inclusive democracy is a political theory and political project that aims for direct democracy in all fields of social life: political democracy in the form of face-to-face assemblies which are confederated, economic democracy in a stateless, moneyless and marketless economy, democracy in the social realm, i.e. self-management in places of work and education, and ecological democracy which aims to reintegrate society and nature. The theoretical project of inclusive democracy emerged from the work of political philosopher Takis Fotopoulos in "Towards An Inclusive Democracy" and was further developed in the journal Democracy & Nature and its successor The International Journal of Inclusive Democracy. The basic unit of decision making in an inclusive democracy is the demotic assembly, i.e. the assembly of demos, the citizen body in a given geographical area which may encompass a town and the surrounding villages, or even neighbourhoods of large cities. An inclusive democracy today can only take the form of a confederal democracy that is based on a network of administrative councils whose members or delegates are elected from popular face-to-face democratic assemblies in the various demoi. Thus, their role is purely administrative and practical, not one of policy-making like that of representatives in representative democracy. The citizen body is advised by experts but it is the citizen body which functions as the ultimate decision-taker. Authority can be delegated to a segment of the citizen body to carry out specific duties, for example, to serve as members of popular courts, or of regional and confederal councils. Such delegation is made, in principle, by lot, on a rotation basis, and is always recallable by the citizen body. Delegates to regional and confederal bodies should have specific mandates. Participatory politics A Parpolity or Participatory Polity is a theoretical form of democracy that is ruled by a Nested Council structure. The guiding philosophy is that people should have decision making power in proportion to how much they are affected by the decision. Local councils of 25–50 people are completely autonomous on issues that affect only them, and these councils send delegates to higher level councils who are again autonomous regarding issues that affect only the population affected by that council. A council court of randomly chosen citizens serves as a check on the tyranny of the majority, and rules on which body gets to vote on which issue. Delegates may vote differently from how their sending council might wish but are mandated to communicate the wishes of their sending council. Delegates are recallable at any time. Referendums are possible at any time via votes of most lower-level councils, however, not everything is a referendum as this is most likely a waste of time. A parpolity is meant to work in tandem with a participatory economy. Cosmopolitan Cosmopolitan democracy, also known as Global democracy or World Federalism, is a political system in which democracy is implemented on a global scale, either directly or through representatives. An important justification for this kind of system is that the decisions made in national or regional democracies often affect people outside the constituency who, by definition, cannot vote. By contrast, in a cosmopolitan democracy, the people who are affected by decisions also have a say in them. According to its supporters, any attempt to solve global problems is undemocratic without some form of cosmopolitan democracy. The general principle of cosmopolitan democracy is to expand some or all of the values and norms of democracy, including the rule of law; the non-violent resolution of conflicts; and equality among citizens, beyond the limits of the state. To be fully implemented, this would require reforming existing international organisations, e.g. the United Nations, as well as the creation of new institutions such as a World Parliament, which ideally would enhance public control over, and accountability in, international politics. Cosmopolitan Democracy has been promoted, among others, by physicist Albert Einstein, writer Kurt Vonnegut, columnist George Monbiot, and professors David Held and Daniele Archibugi. The creation of the International Criminal Court in 2003 was seen as a major step forward by many supporters of this type of cosmopolitan democracy. Creative democracy Creative Democracy is advocated by American philosopher John Dewey. The main idea about Creative Democracy is that democracy encourages individual capacity building and the interaction among the society. Dewey argues that democracy is a way of life in his work of "Creative Democracy: The Task Before Us" and an experience built on faith in human nature, faith in human beings, and faith in working with others. Democracy, in Dewey's view, is a moral ideal requiring actual effort and work by people; it is not an institutional concept that exists outside of ourselves. "The task of democracy", Dewey concludes, "is forever that of creation of a freer and more humane experience in which all share and to which all contribute". Guided democracy Guided democracy is a form of democracy that incorporates regular popular elections, but which often carefully "guides" the choices offered to the electorate in a manner that may reduce the ability of the electorate to truly determine the type of government exercised over them. Such democracies typically have only one central authority which is often not subject to meaningful public review by any other governmental authority. Russian-style democracy has often been referred to as a "Guided democracy." Russian politicians have referred to their government as having only one center of power/ authority, as opposed to most other forms of democracy which usually attempt to incorporate two or more naturally competing sources of authority within the same government. Non-governmental democracy Aside from the public sphere, similar democratic principles and mechanisms of voting and representation have been used to govern other kinds of groups. Many non-governmental organisations decide policy and leadership by voting. Most trade unions and cooperatives are governed by democratic elections. Corporations are controlled by shareholders on the principle of one share, one vote—sometimes supplemented by workplace democracy. Amitai Etzioni has postulated a system that fuses elements of democracy with sharia law, termed Islamocracy. There is also a growing number of Democratic educational institutions such as Sudbury schools that are co-governed by students and staff. Justification Several justifications for democracy have been postulated. Legitimacy Social contract theory argues that the legitimacy of government is based on consent of the governed, i.e. an election, and that political decisions must reflect the general will. Better decision-making Condorcet's jury theorem is logical proof that if each decision-maker has a better than chance probability of making the right decision, then having the largest number of decision-makers, i.e. a democracy, will result in the best decisions. This has also been argued by theories of the wisdom of the crowd. Democratic peace Democratic peace theory claims that liberal democracies do not go to war against each other. Economic success In Why Nations Fail, economists Daron Acemoglu and James A. Robinson argue that democracies are more economically successful because undemocratic political systems tend to limit markets and favor monopolies at the expense of the creative destruction which is necessary for sustained economic growth. A 2019 study by Acemoglu and others estimated that countries switching to democratic from authoritarian rule had on average a 20% higher GDP after 25 years than if they had remained authoritarian. The study examined 122 transitions to democracy and 71 transitions to authoritarian rule, occurring from 1960 to 2010. Acemoglu said this was because democracies tended to invest more in health care and human capital, and reduce special treatment of regime allies. Criticism Arrow's theorem Arrow's impossibility theorem suggests that democracy is logically incoherent. This is based on a certain set of criteria for democratic decision-making being inherently conflicting, i.e. these three "fairness" criteria: Kenneth Arrow summarised the implications of the theorem in a non-mathematical form, stating that "no voting method is fair", "every ranked voting method is flawed", and "the only voting method that isn't flawed is a dictatorship". However, Arrow's formal premises can be considered overly strict, and with their reasonable weakening, the logical incoherence of democracy looks much less critical. Inefficiencies Some economists have criticized the efficiency of democracy, citing the premise of the irrational voter, or a voter who makes decisions without all of the facts or necessary information in order to make a truly informed decision. Another argument is that democracy slows down processes because of the amount of input and participation needed in order to go forward with a decision. A common example often quoted to substantiate this point is the high economic development achieved by China (a non-democratic country) as compared to India (a democratic country). According to economists, the lack of democratic participation in countries like China allows for unfettered economic growth. On the other hand, Socrates believed that democracy without educated masses (educated in the broader sense of being knowledgeable and responsible) would only lead to populism being the criteria to become an elected leader and not competence. This would ultimately lead to a societal demise. This was quoted by Plato in book 10 of The Republic, in Socrates' conversation with Adimantus. Socrates was of the opinion that the right to vote must not be an indiscriminate right (for example by birth or citizenship), but must be given only to people who thought sufficiently of their choice. Popular rule as a façade The 20th-century Italian thinkers Vilfredo Pareto and Gaetano Mosca (independently) argued that democracy was illusory, and served only to mask the reality of elite rule. Indeed, they argued that elite oligarchy is the unbendable law of human nature, due largely to the apathy and division of the masses (as opposed to the drive, initiative and unity of the elites), and that democratic institutions would do no more than shift the exercise of power from oppression to manipulation. As Louis Brandeis once professed, "We may have democracy, or we may have wealth concentrated in the hands of a few, but we can't have both.". British writer Ivo Mosley, grandson of blackshirt Oswald Mosley describes in In the Name of the People: Pseudo-Democracy and the Spoiling of Our World, how and why current forms of electoral governance are destined to fall short of their promise. A study led by Princeton professor Martin Gilens of 1,779 U.S. government decisions concluded that "elites and organized groups representing business interests have substantial independent impacts on U.S. government policy, while average citizens and mass-based interest groups have little or no independent influence." Mob rule Plato's The Republic presents a critical view of democracy through the narration of Socrates: "Democracy, which is a charming form of government, full of variety and disorder, and dispensing a sort of equality to equals and unequaled alike." In his work, Plato lists 5 forms of government from best to worst. Assuming that the Republic was intended to be a serious critique of the political thought in Athens, Plato argues that only Kallipolis, an aristocracy led by the unwilling philosopher-kings (the wisest men), is a just form of government. James Madison critiqued democracy in Federalist No. 10, arguing that a republic is a preferable form of government, saying: "... democracies have ever been spectacles of turbulence and contention; have ever been found incompatible with personal security or the rights of property; and have in general been as short in their lives as they have been violent in their deaths." Madison offered that republics were superior to democracies because republics safeguarded against tyranny of the majority, stating in Federalist No. 10: "the same advantage which a republic has over a democracy, in controlling the effects of faction, is enjoyed by a large over a small republic". Thomas Jefferson warned that "an elective despotism is not the government we fought for." Political instability More recently, democracy is criticised for not offering enough political stability. As governments are frequently elected on and off there tends to be frequent changes in the policies of democratic countries both domestically and internationally. Even if a political party maintains power, vociferous, headline-grabbing protests and harsh criticism from the popular media are often enough to force sudden, unexpected political change. Frequent policy changes with regard to business and immigration are likely to deter investment and so hinder economic growth. For this reason, many people have put forward the idea that democracy is undesirable for a developing country in which economic growth and the reduction of poverty are top priorities. This opportunist alliance not only has the handicap of having to cater to too many ideologically opposing factions, but it is usually short-lived since any perceived or actual imbalance in the treatment of coalition partners, or changes to leadership in the coalition partners themselves, can very easily result in the coalition partner withdrawing its support from the government. Biased media has been accused of causing political instability, resulting in the obstruction | overarching concept that includes the functioning of diverse institutions which are not easy to measure, strong limitations exist in quantifying and econometrically measuring the potential effects of democracy or its relationship with other phenomena—whether inequality, poverty, education etc. Given the constraints in acquiring reliable data with within-country variation on aspects of democracy, academics have largely studied cross-country variations.

The populace has been conservative, approving only about 10% of the initiatives put before them; in addition, they have often opted for a version of the initiative rewritten by government. Examples include the extensive use of referendums in the US state of California, which is a state that has more than 20 million voters. In New England, Town meetings are often used, especially in rural areas, to manage local government. This creates a hybrid form of government, with a local direct democracy and a representative state government. For example, most Vermont towns hold annual town meetings in March in which town officers are elected, budgets for the town and schools are voted on, and citizens have the opportunity to speak and be heard on political matters. Variants Constitutional monarchy Many countries such as the United Kingdom, Spain, the Netherlands, Belgium, Scandinavian countries, Thailand, Japan and Bhutan turned powerful monarchs into constitutional monarchs with limited or, often gradually, merely symbolic roles. For example, in the predecessor states to the United Kingdom, constitutional monarchy began to emerge and has continued uninterrupted since the Glorious Revolution of 1688 and passage of the Bill of Rights 1689. Strongly limited constitutional monarchies, such as the United Kingdom, have been referred to as crowned republics by writers such as H. G. Wells. In other countries, the monarchy was abolished along with the aristocratic system (as in France, China, Russia, Germany, Austria, Hungary, Italy, Greece and Egypt). An elected person, with or without significant powers, became the head of state in these countries. Elite upper houses of legislatures, which often had lifetime or hereditary tenure, were common in many states. Over time, these either had their powers limited (as with the British House of Lords) or else became elective and remained powerful (as with the Australian Senate). Republic The term republic has many different meanings, but today often refers to a representative democracy with an elected head of state, such as a president, serving for a limited term, in contrast to states with a hereditary monarch as a head of state, even if these states also are representative democracies with an elected or appointed head of government such as a prime minister. The Founding Fathers of the United States rarely praised and often criticised democracy, which in their view often came without the protection of a constitution enshrining inalienable rights; James Madison argued, especially in The Federalist No. 10, that what distinguished a direct democracy from a republic was that the former became weaker as it got larger and suffered more violently from the effects of faction, whereas a republic could get stronger as it got larger and combats faction by its very structure. Professors Richard Ellis of Willamette University and Michael Nelson of Rhodes College argue that much constitutional thought, from Madison to Lincoln and beyond, has focused on "the problem of majority tyranny." They conclude, "The principles of republican government embedded in the Constitution represent an effort by the framers to ensure that the inalienable rights of life, liberty, and the pursuit of happiness would not be trampled by majorities." What was critical to American values, John Adams insisted, was that the government be "bound by fixed laws, which the people have a voice in making, and a right to defend." As Benjamin Franklin was exiting after writing the U.S. constitution, Elizabeth Willing Powel asked him "Well, Doctor, what have we got—a republic or a monarchy?". He replied "A republic—if you can keep it." Liberal democracy A liberal democracy is a representative democracy in which the ability of the elected representatives to exercise decision-making power is subject to the rule of law, and moderated by a constitution or laws that emphasise the protection of the rights and freedoms of individuals, and which places constraints on the leaders and on the extent to which the will of the majority can be exercised against the rights of minorities (see civil liberties). In a liberal democracy, it is possible for some large-scale decisions to emerge from the many individual decisions that citizens are free to make. In other words, citizens can "vote with their feet" or "vote with their dollars", resulting in significant informal government-by-the-masses that exercises many "powers" associated with formal government elsewhere. Socialist Socialist thought has several different views on democracy. Social democracy, democratic socialism, and the dictatorship of the proletariat (usually exercised through Soviet democracy) are some examples. Many democratic socialists and social democrats believe in a form of participatory, industrial, economic and/or workplace democracy combined with a representative democracy. Within Marxist orthodoxy there is a hostility to what is commonly called "liberal democracy", which is simply referred to as parliamentary democracy because of its often centralised nature. Because of orthodox Marxists' desire to eliminate the political elitism they see in capitalism, Marxists, Leninists and Trotskyists believe in direct democracy implemented through a system of communes (which are sometimes called soviets). This system ultimately manifests itself as council democracy and begins with workplace democracy. Anarchist Anarchists are split in this domain, depending on whether they believe that a majority-rule is tyrannic or not. To many anarchists, the only form of democracy considered acceptable is direct democracy. Pierre-Joseph Proudhon argued that the only acceptable form of direct democracy is one in which it is recognised that majority decisions are not binding on the minority, even when unanimous. However, anarcho-communist Murray Bookchin criticised individualist anarchists for opposing democracy, and says "majority rule" is consistent with anarchism. Some anarcho-communists oppose the majoritarian nature of direct democracy, feeling that it can impede individual liberty and opt-in favour of a non-majoritarian form of consensus democracy, similar to Proudhon's position on direct democracy. Henry David Thoreau, who did not self-identify as an anarchist but argued for "a better government" and is cited as an inspiration by some anarchists, argued that people should not be in the position of ruling others or being ruled when there is no consent. Sortition Sometimes called "democracy without elections", sortition chooses decision makers via a random process. The intention is that those chosen will be representative of the opinions and interests of the people at large, and be more fair and impartial than an elected official. The technique was in widespread use in Athenian Democracy and Renaissance Florence and is still used in modern jury selection. Consociational A consociational democracy allows for simultaneous majority votes in two or more ethno-religious constituencies, and policies are enacted only if they gain majority support from both or all of them. Consensus democracy A consensus democracy, in contrast, would not be dichotomous. Instead, decisions would be based on a multi-option approach, and policies would be enacted if they gained sufficient support, either in a purely verbal agreement or via a consensus vote—a multi-option preference vote. If the threshold of support were at a sufficiently high level, minorities would be as it were protected automatically. Furthermore, any voting would be ethno-colour blind. Supranational Qualified majority voting is designed by the Treaty of Rome to be the principal method of reaching decisions in the European Council of Ministers. This system allocates votes to member states in part according to their population, but heavily weighted in favour of the smaller states. This might be seen as a form of representative democracy, but representatives to the Council might be appointed rather than directly elected. Inclusive Inclusive democracy is a political theory and political project that aims for direct democracy in all fields of social life: political democracy in the form of face-to-face assemblies which are confederated, economic democracy in a stateless, moneyless and marketless economy, democracy in the social realm, i.e. self-management in places of work and education, and ecological democracy which aims to reintegrate society and nature. The theoretical project of inclusive democracy emerged from the work of political philosopher Takis Fotopoulos in "Towards An Inclusive Democracy" and was further developed in the journal Democracy & Nature and its successor The International Journal of Inclusive Democracy. The basic unit of decision making in an inclusive democracy is the demotic assembly, i.e. the assembly of demos, the citizen body in a given geographical area which may encompass a town and the surrounding villages, or even neighbourhoods of large cities. An inclusive democracy today can only take the form of a confederal democracy that is based on a network of administrative councils whose members or delegates are elected from popular face-to-face democratic assemblies in the various demoi. Thus, their role is purely administrative and practical, not one of policy-making like that of representatives in representative democracy. The citizen body is advised by experts but it is the citizen body which functions as the ultimate decision-taker. Authority can be delegated to a segment of the citizen body to carry out specific duties, for example, to serve as members of popular courts, or of regional and confederal councils. Such delegation is made, in principle, by lot, on a rotation basis, and is always recallable by the citizen body. Delegates to regional and confederal bodies should have specific mandates. Participatory politics A Parpolity or Participatory Polity is a theoretical form of democracy that is ruled by a Nested Council structure. The guiding philosophy is that people should have decision making power in proportion to how much they are affected by the decision. Local councils of 25–50 people are completely autonomous on issues that affect only them, and these councils send delegates to higher level councils who are again autonomous regarding issues that affect only the population affected by that council. A council court of randomly chosen citizens serves as a check on the tyranny of the majority, and rules on which body gets to vote on which issue. Delegates may vote differently from how their sending council might wish but are mandated to communicate the wishes of their sending council. Delegates are recallable at any time. Referendums are possible at any time via votes of most lower-level councils, however, not everything is a referendum as this is most likely a waste of time. A parpolity is meant to work in tandem with a participatory economy. Cosmopolitan Cosmopolitan democracy, also known as Global democracy or World Federalism, is a political system in which democracy is implemented on a global scale, either directly or through representatives. An important justification for this kind of system is that the decisions made in national or regional democracies often affect people outside the constituency who, by definition, cannot vote. By contrast, in a cosmopolitan democracy, the people who are affected by decisions also have a say in them. According to its supporters, any attempt to solve global problems is undemocratic without some form of cosmopolitan democracy. The general principle of cosmopolitan democracy is to expand some or all of the values and norms of democracy, including the rule of law; the non-violent resolution of conflicts; and equality among citizens, beyond the limits of the state. To be fully implemented, this would require reforming existing international organisations, e.g. the United Nations, as well as the creation of new institutions such as a World Parliament, which ideally would enhance public control over, and accountability in, international politics. Cosmopolitan Democracy has been promoted, among others, by physicist Albert Einstein, writer Kurt Vonnegut, columnist George Monbiot, and professors David Held and Daniele Archibugi. The creation of the International Criminal Court in 2003 was seen as a major step forward by many supporters of this type of cosmopolitan democracy. Creative democracy Creative Democracy is advocated by American philosopher John Dewey. The main idea about Creative Democracy is that democracy encourages individual capacity building and the interaction among the society. Dewey argues that democracy is a way of life in his work of "Creative Democracy: The Task Before Us" and an experience built on faith in human nature, faith in human beings, and faith in working with others. Democracy, in Dewey's view, is a moral ideal requiring actual effort and work by people; it is not an institutional concept that exists outside of ourselves. "The task of democracy", Dewey concludes, "is forever that of creation of a freer and more humane experience in which all share and to which all contribute". Guided democracy Guided democracy is a form of democracy that incorporates regular popular elections, but which often carefully "guides" the choices offered to the electorate in a manner that may reduce the ability of the electorate to truly determine the type of government exercised over them. Such democracies typically have only one central authority which is often not subject to meaningful public review by any other governmental authority. Russian-style democracy has often been referred to as a "Guided democracy." Russian politicians have referred to their government as having only one center of power/ authority, as opposed to most other forms of democracy which usually attempt to incorporate two or more naturally competing sources of authority within the same government. Non-governmental democracy Aside from the public sphere, similar democratic principles and mechanisms of voting and representation have been used to govern other kinds of groups. Many non-governmental organisations decide policy and leadership by voting. Most trade unions and cooperatives are governed by democratic elections. Corporations are controlled by shareholders on the principle of one share, one vote—sometimes supplemented by workplace democracy. Amitai Etzioni has postulated a system that fuses elements of democracy with sharia law, termed Islamocracy. There is also a growing number of Democratic educational institutions such as Sudbury schools that are co-governed by students and staff. Justification Several justifications for democracy have been postulated. Legitimacy Social contract theory argues that the legitimacy of government is based on consent of the governed, i.e. an election, and that political decisions must reflect the general will. Better decision-making Condorcet's jury theorem is logical proof that if each decision-maker has a better than chance probability of making the right decision, then having the largest number of decision-makers, i.e. a democracy, will result in the best decisions. This has also been argued by theories of the wisdom of the crowd. Democratic peace Democratic peace theory claims that liberal democracies do not go to war against each other. Economic success In Why Nations Fail, economists Daron Acemoglu and James A. Robinson argue that democracies are more economically successful because undemocratic political systems tend to limit markets and favor monopolies at the expense of the creative destruction which is necessary for sustained economic growth. A 2019 study by Acemoglu and others estimated that countries switching to democratic from authoritarian rule had on average a 20% higher GDP after 25 years than if they had remained authoritarian. The study examined 122 transitions to democracy and 71 transitions to authoritarian rule, occurring from 1960 to 2010. Acemoglu said this was because democracies tended to invest more in health care and human capital, and reduce special treatment of regime allies. Criticism Arrow's theorem Arrow's impossibility theorem suggests that democracy is logically incoherent. This is based on a certain set of criteria for democratic decision-making being inherently conflicting, i.e. these three "fairness" criteria: Kenneth Arrow summarised the implications of the theorem in a non-mathematical form, stating that "no voting method is fair", "every ranked voting method is flawed", and "the only voting method that isn't flawed is a dictatorship". However, Arrow's formal premises can be considered overly strict, and with their reasonable weakening, the logical incoherence of democracy looks much less critical. Inefficiencies Some economists have criticized the efficiency of democracy, citing the premise of the irrational voter, or a voter who makes decisions without all of the facts or necessary information in order to make a truly informed decision. Another argument is that democracy slows down processes because of the amount of input and participation needed in order to go forward with a decision. A common example often quoted to substantiate this point is the high economic development achieved by China (a non-democratic country) as compared to India (a democratic country). According to economists, the lack of democratic participation in countries like China allows for unfettered economic growth. On the other hand, Socrates believed that democracy without educated masses (educated in the broader sense of being knowledgeable and responsible) would only lead to populism being the criteria to become an elected leader and not competence. This would ultimately lead to a societal demise. This was quoted by Plato in book 10 of The Republic, in Socrates' conversation with Adimantus. Socrates was of the opinion that the right to vote must not be an indiscriminate right (for example by birth or citizenship), but must be given only to people who thought sufficiently of their choice. Popular rule as a façade The 20th-century Italian thinkers Vilfredo Pareto and Gaetano Mosca (independently) argued that democracy was illusory, and served only to mask the reality of elite rule. Indeed, they argued that elite oligarchy is the unbendable law of human nature, due largely to the apathy and division of the masses (as opposed to the drive, initiative and unity of the elites), and that democratic institutions would do no more than shift the exercise of power from oppression to manipulation. As Louis Brandeis once professed, "We may have democracy, or we may have wealth concentrated in the hands of a few, but we can't have both.". British writer Ivo Mosley, grandson of blackshirt Oswald Mosley describes in In the Name of the People: Pseudo-Democracy and the Spoiling of Our World, how and why current forms of electoral governance are destined to fall short of their promise. A study led by Princeton professor Martin Gilens of 1,779 U.S. government decisions concluded that "elites and organized groups representing business interests have substantial independent impacts on U.S. government policy, while average citizens and mass-based interest groups have little or no independent influence." Mob rule Plato's The Republic presents a critical view of democracy through the narration of Socrates: "Democracy, which is a charming form of government, full of variety and disorder, and dispensing a sort of equality to equals and unequaled alike." In his work, Plato lists 5 forms of government from best to worst. Assuming that the Republic was intended to be a serious critique of the political thought in Athens, Plato argues that only Kallipolis, an aristocracy led by the unwilling philosopher-kings (the wisest men), is a just form of government. James Madison critiqued democracy in Federalist No. 10, arguing that a republic is a preferable form of government, saying: "... democracies have ever been spectacles of turbulence and contention; have ever been found incompatible with personal security or the rights of property; and have in general been as short in their lives as they have been violent in their deaths." Madison offered that republics were superior to democracies because republics safeguarded against tyranny of the majority, stating in Federalist No. 10: "the same advantage which a republic has over a democracy, in controlling the effects of faction, is enjoyed by a large over a small republic". Thomas Jefferson warned that "an elective despotism is not the government we fought for." Political instability More recently, democracy is criticised for not offering enough political stability. As governments are frequently elected on and off there tends to be frequent changes in the policies of democratic countries both domestically and internationally. Even if a political party maintains power, vociferous, headline-grabbing protests and harsh criticism from the popular media are often enough to force sudden, unexpected political change. Frequent policy changes with regard to business and immigration are likely to deter investment and so hinder economic growth. For this reason, many people have put forward the idea that democracy is undesirable for a developing country in which economic growth and the reduction of poverty are top priorities. This opportunist alliance not only has the handicap of having to cater to too many ideologically opposing factions, but it is usually short-lived since any perceived or actual imbalance in the treatment of coalition partners, or changes to leadership in the coalition partners themselves, can very easily result in the coalition partner withdrawing its support from the government. Biased media has been accused of causing political instability, resulting in the obstruction of democracy, rather than its promotion. Opposition Democracy in modern times has almost always faced opposition from the previously existing government, and many times it has faced opposition from social elites. The implementation of a democratic government within a non-democratic state is typically brought about by democratic revolution. Democratization Several philosophers and researchers have outlined historical and social factors seen as supporting the evolution of democracy. Other commentators have mentioned the influence of economic development. In a related theory, Ronald Inglehart suggests that improved living-standards in modern developed countries can convince people that they can take their basic survival for granted, leading to increased emphasis on self-expression values, which correlates closely with democracy. Douglas M. Gibler and Andrew Owsiak in their study argued about the importance of peace and stable borders for the development of democracy. It has often been assumed that democracy causes peace, but this study shows that, historically, peace has almost always predated the establishment of democracy. Carroll Quigley concludes that the characteristics of weapons are the main predictor of democracy:see also Chester G Starr, Review of Weapons Systems and Political Stability, American Historical Review, Feb 1984, p. 98, available at carrollquigley.net Democracy—this scenario—tends to emerge only when the best weapons available are easy for individuals to obtain and use. By the 1800s, guns were the best personal weapons available, and in the United States of America (already nominally democratic), almost everyone could afford to buy a gun, and could learn how to use it fairly easily. Governments couldn't do any better: it became the age of mass armies of citizen soldiers with guns. Similarly, Periclean Greece was an age of the citizen soldier and democracy. Other theories stressed the relevance of education and of human capital—and within them of cognitive ability to increasing tolerance, rationality, political literacy and participation. Two effects of education and cognitive ability are distinguished:Compare: a cognitive effect (competence to make rational choices, better information-processing) an ethical effect (support of democratic values, freedom, human rights etc.), which itself depends on intelligence. Evidence consistent with conventional theories of why democracy emerges and is sustained has been hard to come by. Statistical analyses have challenged modernisation theory by demonstrating that there is no reliable evidence for the claim that democracy is more likely to emerge when countries become wealthier, more educated, or less unequal. In fact, empirical evidence shows that economic growth and education may not lead to increased demand for democratization as modernization theory suggests: historically, most countries attained high levels of access to primary education well before transitioning to democracy. Rather than acting as a catalyst for democratization, in some situations education provision may instead be used by non-democratic regimes to indoctrinate their subjects and strengthen their power. The assumed link between education and economic growth is called into question when analyzing empirical evidence. Across different countries, the correlation between education attainment and math test scores is very weak (.07). A similarly weak relationship exists between per-pupil expenditures and math competency (.26). Additionally, historical evidence suggests that average human capital (measured using literacy rates) of the masses does not explain the onset of industrialization in France from 1750 to 1850 despite arguments to the contrary. Together, these findings show that education does not always promote human capital and economic growth as is generally argued to be the case. Instead, the evidence implies that education provision often falls short of its expressed goals, or, alternatively, that political actors use education to promote goals other than economic growth and development. Some scholars have searched for the "deep" determinants of contemporary political institutions, be they geographical or demographic. More inclusive institutions lead to democracy because as people gain more power, they are able to demand more from the elites, who in turn have to concede more things to keep their position. This virtuous circle may end up in democracy. An example of this is the disease environment. Places with different mortality rates had different populations and productivity levels around the world. For example, in Africa, the tsetse fly—which afflicts humans and livestock—reduced the ability of Africans to plow the land. This made Africa less settled. As a consequence, political power was less concentrated. This also affected the colonial institutions European countries established in Africa. Whether colonial settlers could live or not in a place made them develop different institutions which led to different economic and social paths. This also affected the distribution of power and the collective actions people could take. As a result, some African countries ended up having democracies and others autocracies. An example of geographical determinants for democracy is having access to coastal areas and rivers. This natural endowment has a positive relation with economic development thanks to the benefits of trade. Trade brought economic development, which in turn, broadened power. Rulers wanting to increase revenues had to protect property-rights to create incentives for people to invest. As more people had more power, more concessions had to be made by the ruler and in many places this process lead to democracy. These determinants defined the structure of the society moving the balance of political power. Robert Michels asserts that although democracy can never be fully realised, democracy may be developed automatically in the act of striving for democracy: The peasant in the fable, when on his deathbed, tells his sons that a treasure is buried in the field. After the old man's death the sons dig everywhere in order to discover the treasure. They do not find it. But their indefatigable labor improves the soil and secures for them a comparative well-being. The treasure in the fable may well symbolise democracy. Disruption Some democratic governments have experienced sudden state collapse and regime change to an undemocratic form of government. Domestic military coups or rebellions are the most common means by which democratic governments have been overthrown. (See List of coups and coup attempts by country and List of civil wars.) Examples include the Spanish Civil War, the Coup of 18 Brumaire that ended the First French Republic, and the 28 May 1926 coup d'état which ended the First Portuguese Republic. Some military coups are supported by foreign governments, such as the 1954 Guatemalan coup d'état and the 1953 Iranian coup d'état. Other types of a sudden end to democracy include: Invasion, for example the German occupation of Czechoslovakia, and the fall of South Vietnam. Self-coup, in which the leader of the government extra-legally seizes all power or unlawfully extends the term in office. This can be done through: Suspension of the constitution by decree, such as with the 1992 Peruvian coup d'état An "electoral self-coup" using election fraud to obtain re-election of a previously fairly elected official or political party. For example, in the 1999 Ukrainian presidential election, 2003 Russian legislative election, and 2004 Russian presidential election. Royal coup, in which a monarch not normally involved in government seizes all power. For example, the 6 January Dictatorship, begun in 1929 when King Alexander I of Yugoslavia dismissed parliament and started ruling by decree. Democratic backsliding can end democracy in a gradual manner, by increasing emphasis on national security and eroding free and fair elections, freedom of expression, independence of the judiciary, rule of law. A famous example is the Enabling Act of 1933, which lawfully ended democracy in Weimar Germany and marked the transition to Nazi Germany. Temporary or long-term political violence and government interference can prevent free and fair elections, which erode the democratic nature of governments. This has happened on a local level even in well-established democracies like the United States; for example, the Wilmington insurrection of 1898 and African-American disfranchisement after the Reconstruction era. Importance of mass media The theory of democracy relies on the implicit assumption that voters are well informed about social issues, policies, and candidates so that they can make a truly informed decision. Since the late 20'th century there has been a growing concern that voters may be poorly informed because the news media are focusing more on entertainment and gossip and less on serious journalistic research on political issues. The media professors Michael Gurevitch and Jay Blumler have proposed a number of functions that the mass media are expected to fulfill in a democracy: Surveillance of the sociopolitical environment Meaningful agenda setting Platforms for an intelligible and illuminating advocacy Dialogue across a diverse range of views Mechanisms for holding officials to account for how they have exercised power Incentives for citizens to learn, choose, and become involved A principled resistance to the efforts of forces outside the media to subvert their independence, integrity, and ability to serve the audience A sense of respect for the audience member, as potentially concerned and able to make sense of his or her political environment This proposal has inspired a lot of discussions over whether the news media are actually fulfilling the requirements that a well functioning democracy requires. Commercial mass media are generally not accountable to anybody but their owners, and they have no obligation to serve a democratic function. They are controlled mainly by economic market forces. Fierce economic competition may force the mass media to divert themselves from any democratic ideals and focus entirely on how to survive the competition. The tabloidization and popularization of the news media is seen in an increasing focus on human examples rather than statistics and principles. There is more focus on politicians as personalities and less focus on political issues in the popular media. Election campaigns are covered more as horse races and less as debates about ideologies and issues. The dominating media focus on spin, conflict, and competitive strategies has made voters perceive the politicians as egoists rather than idealists. This fosters mistrust and a cynical attitude to politics, less civic engagement, and less interest in voting. The ability to find effective political solutions to social problems is hampered when problems tend to be blamed on individuals rather than on structural causes. This person-centered focus may have far-reaching consequences not only for domestic problems but also for foreign policy when international conflicts are blamed on foreign heads of state rather than on political and economic structures. A strong media focus on fear and terrorism has allowed military logic to penetrate public institutions, leading to increased surveillance and the erosion of civil rights. The responsiveness and accountability of the democratic system is compromised when lack of access to substantive, diverse, and undistorted information is handicapping the citizens' capability of evaluating the political process. The fast pace and trivialization in the competitive news media is dumbing down the political debate. Thorough and balanced investigation of complex political issues does not fit into this format. The political communication is characterized by short time horizons, short slogans, simple explanations, and simple solutions. This is conducive to political populism rather than serious deliberation. Commercial mass media are often differentiated along the political spectrum so that people can hear mainly opinions that they already agree with. Too much controversy and diverse opinions are not always profitable for the commercial news media. Political polarization is emerging when different people read different news and watch different TV channels. This polarization has been worsened by the emergence of the social media that allow people to communicate mainly with groups of like-minded people, the so-called echo chambers. Extreme political polarization may undermine the trust in democratic institutions, leading to erosion of civil rights and free speech and in some cases even reversion to autocracy. Many media scholars have discussed non-commercial news media with public service obligations as a means to improve the democratic process by providing the kind of political contents that a free market does not provide. The World Bank has recommended public service broadcasting in order to strengthen democracy in developing countries. These broadcasting services should be accountable to an independent regulatory body that is adequately protected from interference from political and economic interests. Public service media have an obligation to provide reliable information to voters. Many countries have publicly funded radio and television stations with public service obligations, especially in Europe and Japan, while such media are weak or non-existent in other countries including the USA. Several studies have shown that the stronger the dominance of commercial broadcast media over public service media, the less the amount of policy-relevant information in the media and the more focus on horse race journalism, personalities, and the pecadillos of politicians. Public service broadcasters are characterized by more policy-relevant information and more respect for journalistic norms and impartiality than the commercial media. However, the trend of deregulation has put the public service model under increased pressure from competition with commercial media. The emergence of the internet and the social media has profoundly altered the conditions for political communication. The social media have given ordinary citizens easy access to voice their opinion and share information while bypassing the filters of the large news media. |
reasoning Validity (logic) Cogency (disambiguation) | induction may refer to: Deductive reasoning |
= 1 1 or 1 = 1 1010 or 1100 = 1110 The or operator can be used to set bits in a bit field to 1, by or-ing the field with a constant field with the relevant bits set to 1. For example, x = x | 0b00000001 will force the final bit to 1, while leaving other bits unchanged. Logical operation Many languages distinguish between bitwise and logical disjunction by providing two distinct operators; in languages following C, bitwise disjunction is performed with the single pipe operator (|), and logical disjunction with the double pipe (||) operator. Logical disjunction is usually short-circuited; that is, if the first (left) operand evaluates to true, then the second (right) operand is not evaluated. The logical disjunction operator thus usually constitutes a sequence point. In a parallel (concurrent) language, it is possible to short-circuit both sides: they are evaluated in parallel, and if one terminates with value true, the other is interrupted. This operator is thus called the parallel or. Although the type of a logical disjunction expression is boolean in most languages (and thus can only have the value true or false), in some languages (such as Python and JavaScript), the logical disjunction operator returns one of its operands: the first operand if it evaluates to a true value, and the second operand otherwise. Constructive disjunction The Curry–Howard correspondence relates a constructivist form of disjunction to tagged union types. Set theory The membership of an element of a union set in set theory is defined in terms of a logical disjunction: if and only if . Because of this, logical disjunction satisfies many of the same identities as set-theoretic union, such as associativity, commutativity, distributivity, and de Morgan's laws, identifying logical conjunction with set intersection, logical negation with set complement. Natural language The classical denotation for does not precisely match the denotation of disjunctive statements in natural languages such as English. Notably, classical disjunction is inclusive while natural language disjunction is often understood exclusively. 1. Mary is patriotic or quixotic. Mary is not both patriotic and quixotic. This inference has sometimes been understood as an entailment, for instance by Alfred Tarski, who suggested that natural language disjunction is ambiguous between a classical and a nonclassical interpretation. More recent work in pragmatics has shown that this inference can be derived as a conversational implicature on the basis of a semantic denotation which behaves classically. However, disjunctive constructions including Hungarian vagy... vagy and French soit... soit have been argued to be inherently exclusive, rendering ungrammaticality in contexts where an inclusive reading would otherwise be forced. Similar deviations from classical logic have been noted in cases such as free choice disjunction and simplification of disjunctive antecedents, where certain modal operators trigger a conjunction-like interpretation of disjunction. As with exclusivity, these inferences have been analyzed both as implicatures and as entailments arising from a nonclassical interpretation of disjunction. 2. You can have an apple or a pear. You can have an apple and you can have a pear (but you can't have both) In many languages, disjunctive expressions play a role in question formation. For instance, while the following English example can be interpreted as a polar question asking whether it's true | have the value true or false), in some languages (such as Python and JavaScript), the logical disjunction operator returns one of its operands: the first operand if it evaluates to a true value, and the second operand otherwise.

However, disjunctive constructions including Hungarian vagy... vagy and French soit... soit have been argued to be inherently exclusive, rendering ungrammaticality in contexts where an inclusive reading would otherwise be forced. Similar deviations from classical logic have been noted in cases such as free choice disjunction and simplification of disjunctive antecedents, where certain modal operators trigger a conjunction-like interpretation of disjunction. As with exclusivity, these inferences have been analyzed both as implicatures and as entailments arising from a nonclassical interpretation of disjunction. 2. You can have an apple or a pear. You can have an apple and you can have a pear (but you can't have both) In many languages, disjunctive expressions play a role in question formation. For instance, while the following English example can be interpreted as a polar question asking whether it's true that Mary is either a philosopher or a linguist, it can also be interpreted as an alternative question asking which of the two professions is hers. The role of disjunction in these cases has been analyzed using nonclassical logics such as alternative semantics and inquisitive semantics, which have also been adopted to explain the free choice and simplification inferences. 3. Is Mary a philosopher or a linguist? In English, as in many other languages, disjunction is expressed by a coordinating conjunction. Other |
choose salad. I will not choose soup. Therefore, I will choose salad. Here is another example: It is red or it is blue. It is not blue. Therefore, it is red. Inclusive and exclusive disjunction Please observe that the disjunctive syllogism works whether 'or' is considered 'exclusive' or 'inclusive' disjunction. See below for the definitions of these terms. There are two kinds of logical disjunction: inclusive means "and/or"—at least one of them is true, or maybe both. exclusive ("xor") means exactly one must be true, but they cannot both be. The widely used English language concept of or is often ambiguous between these two meanings, but the difference is pivotal in evaluating disjunctive arguments. This argument: P or Q. Not P. Therefore, Q. is valid and indifferent between both meanings. However, only in the exclusive meaning is the following form valid: Either (only) P or (only) Q. P. Therefore, not Q. | An example in English: The breach is a safety violation, or it is not subject to fines. The breach is not a safety violation. Therefore, it is not subject to fines. Propositional logic In propositional logic, disjunctive syllogism (also known as disjunction elimination and or elimination, or abbreviated ∨E), is a valid rule of inference. If we are told that at least one of two statements is true; and also told that it is not the former that is true; we can infer that it has to be the latter that is true. If P is true or Q is true and P is false, then Q is true. The reason this is called "disjunctive syllogism" is that, first, it is a syllogism, a three-step argument, and second, it contains a logical disjunction, which simply means an "or" statement. "P or Q" is a disjunction; P and Q are called the statement's disjuncts. The rule makes it possible to eliminate a disjunction from a logical proof. It is the rule that: where the rule is that whenever instances of "", and "" appear on lines of a proof, "" can be placed on a subsequent line. Disjunctive syllogism is closely related and similar to hypothetical syllogism, in that it is also a type of syllogism, and also the name of a rule of inference. |
have a shared origin, such as mouth (of a river) and mouth (of an animal). Polysemes Polysemy is the capacity for a sign (such as a word, phrase, or symbol) to have multiple meanings (that is, multiple semes or sememes and thus multiple senses), usually related by contiguity of meaning within a semantic field. It is thus usually regarded as distinct from homonymy, in which the multiple meanings of a word may be unconnected or unrelated. In logic and mathematics In mathematics, definitions are generally not used to describe existing terms, but to describe or characterize a concept. For naming the object of a definition mathematicians can use either a neologism (this was mainly the case in the past) or words or phrases of the common language (this is generally the case in modern mathematics). The precise meaning of a term given by a mathematical definition is often different than the English definition of the word used, which can lead to confusion, particularly when the meanings are close. For example a set is not exactly the same thing in mathematics and in common language. In some case, the word used can be misleading; for example, a real number has nothing more (or less) real than an imaginary number. Frequently, a definition uses a phrase built with common English words, which has no meaning outside mathematics, such as primitive group or irreducible variety. Classification Authors have used different terms to classify definitions used in formal languages like mathematics. Norman Swartz classifies a definition as "stipulative" if it is intended to guide a specific discussion. A stipulative definition might be considered a temporary, working definition, and can only be disproved by showing a logical contradiction. In contrast, a "descriptive" definition can be shown to be "right" or "wrong" with reference to general usage. Swartz defines a precising definition as one that extends the descriptive dictionary definition (lexical definition) for a specific purpose by including additional criteria. A precising definition narrows the set of things that meet the definition. C.L. Stevenson has identified persuasive definition as a form of stipulative definition which purports to state the "true" or "commonly accepted" meaning of a term, while in reality stipulating an altered use (perhaps as an argument for some specific belief). Stevenson has also noted that some definitions are "legal" or "coercive" – their object is to create or alter rights, duties, or crimes. Recursive definitions A recursive definition, sometimes also called an inductive definition, is one that defines a word in terms of itself, so to speak, albeit in a useful way. Normally this consists of three steps: At least one thing is stated to be a member of the set being defined; this is sometimes called a "base set". All things bearing a certain relation to other members of the set are also to count as members of the set. It is this step that makes the definition recursive. All other things are excluded from the set For instance, we could define a natural number as follows (after Peano): "0" is a natural number. Each natural number has a unique successor, such that: the successor of a natural number is also a natural number; distinct natural numbers have distinct successors; no natural number is succeeded by "0". Nothing else is a natural number. So "0" will have exactly one successor, which for convenience can be called "1". In turn, "1" will have exactly one successor, which could be called "2", and so on. Notice that the second condition in the definition itself refers to natural numbers, and hence involves self-reference. Although this sort of definition involves a form of circularity, it is not vicious, and the definition has been quite successful. In the same way, we can define ancestor as follows: A parent is an ancestor. A parent of an ancestor is an ancestor. Nothing else is an ancestor. Or simply: an ancestor is a parent or a parent of an ancestor. In medicine In medical dictionaries, guidelines and other consensus statements and classifications, definitions should as far as possible be: simple and easy to understand, preferably even by the general public; useful clinically or in related areas where the definition will be used; specific (that is, by reading the definition only, it should ideally not be possible to refer to any other entity than that being defined); measurable; a reflection of current scientific knowledge. Problems Certain rules have traditionally been given for definitions (in particular, genus-differentia definitions). A definition must set out the essential attributes of the thing defined. Definitions should avoid circularity. To define a horse as "a member of the species equus" would convey no information whatsoever. For this reason, Locke adds that a definition of a term must not consist of terms which are synonymous with it. This would be a circular definition, a circulus in definiendo. Note, however, that it is acceptable to define two relative terms in respect of each other. Clearly, we cannot define "antecedent" without using the term "consequent", nor conversely. The definition must not be too wide or too narrow. It must be applicable to everything to which the defined term applies (i.e. not miss anything out), and to nothing else (i.e. not include any things to which the defined term would not truly apply). The definition must not be obscure. The purpose of a definition is to explain the meaning of a term which may be obscure or difficult, by the use of terms that are commonly understood and whose meaning is clear. The violation of this rule is known by the Latin term obscurum per obscurius. However, sometimes scientific and philosophical terms are difficult to define without obscurity. A definition should not be negative where it can be positive. We should not define "wisdom" as the absence of folly, or a healthy thing as whatever is not sick. Sometimes this is unavoidable, however. For example, it appears difficult to define blindness in positive terms rather than as "the absence of sight in a creature that is normally sighted". Fallacies of definition Limitations of definition Given that a natural language such as English contains, at any given time, a finite number of words, any comprehensive list of definitions must either be circular or rely upon primitive notions. If every term of every definiens must itself be defined, "where at last should we stop?" A dictionary, for instance, insofar as it is a comprehensive list of lexical definitions, must resort to circularity. Many philosophers have chosen instead to leave some terms undefined. The scholastic philosophers claimed that the highest genera (called the ten generalissima) cannot be defined, since a higher genus cannot be assigned under which they may fall. Thus being, unity and similar concepts cannot be defined. Locke supposes in An Essay Concerning Human Understanding that the names of simple concepts do not admit of any definition. More recently Bertrand Russell sought to develop a formal language based on logical atoms. Other philosophers, notably Wittgenstein, rejected the need for any undefined simples. Wittgenstein pointed out in his Philosophical Investigations that what counts as a "simple" in one circumstance might not do so in another. He rejected the very idea that every explanation of the meaning of a term needed itself to be explained: "As though an explanation hung in the air unless supported by another one", claiming instead that explanation of a term is only needed to avoid misunderstanding. Locke and Mill also argued that individuals cannot be defined. Names are learned by connecting an idea with a sound, so that speaker and hearer have the same idea when the same word is used. This is not possible when no one else is acquainted with the particular thing that has "fallen under our notice". Russell offered his theory of descriptions in part as a way of defining a proper name, the definition being given by a definite description that "picks out" exactly one individual. Saul Kripke pointed to difficulties with this approach, especially in relation to modality, in his book Naming and Necessity. There is a presumption in the classic example of a definition that the definiens can be stated. Wittgenstein argued that for some terms this is not the case.<ref>Philosophical Investigations</ref> The examples he used include game, number and family. In such cases, he argued, there is no fixed boundary that can be used to provide a definition. Rather, the items are grouped together because of a family resemblance. For terms such as these it is not possible and indeed not necessary to state a definition; | A partitio is simply an intensional definition. A divisio is not an extensional definition, but an exhaustive list of subsets of a set, in the sense that every member of the "divided" set is a member of one of the subsets. An extreme form of divisio lists all sets whose only member is a member of the "divided" set. The difference between this and an extensional definition is that extensional definitions list members, and not subsets. Nominal definitions vs real definitions In classical thought, a definition was taken to be a statement of the essence of a thing. Aristotle had it that an object's essential attributes form its "essential nature", and that a definition of the object must include these essential attributes. The idea that a definition should state the essence of a thing led to the distinction between nominal and real essence—a distinction originating with Aristotle. In the Posterior Analytics, he says that the meaning of a made-up name can be known (he gives the example "goat stag") without knowing what he calls the "essential nature" of the thing that the name would denote (if there were such a thing). This led medieval logicians to distinguish between what they called the quid nominis, or the "whatness of the name", and the underlying nature common to all the things it names, which they called the quid rei, or the "whatness of the thing". The name "hobbit", for example, is perfectly meaningful. It has a quid nominis, but one could not know the real nature of hobbits, and so the quid rei of hobbits cannot be known. By contrast, the name "man" denotes real things (men) that have a certain quid rei. The meaning of a name is distinct from the nature that a thing must have in order that the name apply to it. This leads to a corresponding distinction between nominal and real definitions. A nominal definition is the definition explaining what a word means (i.e., which says what the "nominal essence" is), and is definition in the classical sense as given above. A real definition, by contrast, is one expressing the real nature or quid rei of the thing. This preoccupation with essence dissipated in much of modern philosophy. Analytic philosophy, in particular, is critical of attempts to elucidate the essence of a thing. Russell described essence as "a hopelessly muddle-headed notion". More recently Kripke's formalisation of possible world semantics in modal logic led to a new approach to essentialism. Insofar as the essential properties of a thing are necessary to it, they are those things that it possesses in all possible worlds. Kripke refers to names used in this way as rigid designators. Operational vs. theoretical definitions A definition may also be classified as an operational definition or theoretical definition. Terms with multiple definitions Homonyms A homonym is, in the strict sense, one of a group of words that share the same spelling and pronunciation but have different meanings. Thus homonyms are simultaneously homographs (words that share the same spelling, regardless of their pronunciation) and homophones (words that share the same pronunciation, regardless of their spelling). The state of being a homonym is called homonymy. Examples of homonyms are the pair stalk (part of a plant) and stalk (follow/harass a person) and the pair left (past tense of leave) and left (opposite of right). A distinction is sometimes made between "true" homonyms, which are unrelated in origin, such as skate (glide on ice) and skate (the fish), and polysemous homonyms, or polysemes, which have a shared origin, such as mouth (of a river) and mouth (of an animal). Polysemes Polysemy is the capacity for a sign (such as a word, phrase, or symbol) to have multiple meanings (that is, multiple semes or sememes and thus multiple senses), usually related by contiguity of meaning within a semantic field. It is thus usually regarded as distinct from homonymy, in which the multiple meanings of a word may be unconnected or unrelated. In logic and mathematics In mathematics, definitions are generally not used to describe existing terms, but to describe or characterize a concept. For naming the object of a definition mathematicians can use either a neologism (this was mainly the case in the past) or words or phrases of the common language (this is generally the case in modern mathematics).

The largest scenes were most notably in New York City but also in Philadelphia, San Francisco, Miami, and Washington, D.C. The scene was centered on discotheques, nightclubs, and private loft parties. In the 1970s, notable discos included "Crisco Disco", "The Sanctuary", "Leviticus", "Studio 54" and "Paradise Garage" in New York, "Artemis" in Philadelphia, "Studio One" in Los Angeles, "Dugan's Bistro" in Chicago, and "The Library" in Atlanta. In the late '70s, Studio 54 in Midtown Manhattan was arguably the best known nightclub in the world. This club played a major formative role in the growth of disco music and nightclub culture in general. It was operated by Steve Rubell and Ian Schrager and was notorious for the hedonism that went on within; the balconies were known for sexual encounters, and drug use was rampant. Its dance floor was decorated with an image of the "Man in the Moon" that included an animated cocaine spoon. The "Copacabana", another New York nightclub dating to the 1940s, had a revival in the late 1970s when it embraced disco; it would become the setting of a Barry Manilow song of the same name. In Washington, D.C., large disco clubs such as "The Pier" ("Pier 9") and "The Other Side," originally regarded exclusively as "gay bars," became particularly popular among the capital area's gay and straight college students in the late '70s. By 1979 there were 15,000-20,000 disco nightclubs in the US, many of them opening in suburban shopping centers, hotels and restaurants. The 2001 Club franchises were the most prolific chain of disco clubs in the country. Although many other attempts were made to franchise disco clubs, 2001 was the only one to successfully do so in this time frame. Sound and light equipment Powerful, bass-heavy, hi-fi sound systems were viewed as a key part of the disco club experience. "[Loft-party host David] Mancuso introduced the technologies of tweeter arrays (clusters of small loudspeakers, which emit high-end frequencies, positioned above the floor) and bass reinforcements (additional sets of subwoofers positioned at ground level) at the start of the 1970s to boost the treble and bass at opportune moments, and by the end of the decade sound engineers such as Richard Long had multiplied the effects of these innovations in venues such as the Garage." Typical lighting designs for disco dance floors could include multi-coloured lights that swirl around or flash to the beat, strobe light, an illuminated dance floor and a mirror ball. DJs Disco-era disc jockeys (DJs) would often remix existing songs using reel-to-reel tape machines, and add in percussion breaks, new sections, and new sounds. DJs would select songs and grooves according to what the dancers wanted, transitioning from one song to another with a DJ mixer and using a microphone to introduce songs and speak to the audiences. Other equipment was added to the basic DJ setup, providing unique sound manipulations, such as reverb, equalization, and echo effects unit. Using this equipment, a DJ could do effects such as cutting out all but the bassline of a song and then slowly mixing in the beginning of another song using the DJ mixer's crossfader. Notable U.S. disco DJs include Francis Grasso of The Sanctuary, David Mancuso of The Loft, Frankie Knuckles of the Chicago Warehouse, Larry Levan of the Paradise Garage, Nicky Siano, Walter Gibbons, Karen Mixon Cook, Jim Burgess, John "Jellybean" Benitez, Richie Kulala of Studio 54 and Rick Salsalini. Some DJs were also record producers who created and produced disco songs in the recording studio. Larry Levan, for example, was a prolific record producer as well as a DJ. Because record sales were often dependent on dance floor play by DJs in leading nightclubs, DJs were also influential for the development and popularization of certain types of disco music being produced for record labels. Dance In the early years, dancers in discos danced in a "hang loose" or "freestyle" approach. At first, many dancers improvised their own dance styles and dance steps. Later in the disco era, popular dance styles were developed, including the "Bump", "Penguin", "Boogaloo", "Watergate" and "Robot". By October 1975 the Hustle reigned. It was highly stylized, sophisticated and overtly sexual. Variations included the Brooklyn Hustle, New York Hustle and Latin Hustle. During the disco era, many nightclubs would commonly host disco dance competitions or offer free dance lessons. Some cities had disco dance instructors or dance schools, which taught people how to do popular disco dances such as "touch dancing", "the hustle", and "the cha cha". The pioneer of disco dance instruction was Karen Lustgarten in San Francisco in 1973. Her book The Complete Guide to Disco Dancing (Warner Books 1978) was the first to name, break down and codify popular disco dances as dance forms and distinguish between disco freestyle, partner and line dances. The book topped the New York Times bestseller list for 13 weeks and was translated into Chinese, German and French. In Chicago, the Step By Step disco dance TV show was launched with the sponsorship support of the Coca-Cola company. Produced in the same studio that Don Cornelius used for the nationally syndicated dance/music television show, Soul Train, Step by Step'''s audience grew and the show became a success. The dynamic dance duo of Robin and Reggie led the show. The pair spent the week teaching disco dancing to dancers in the disco clubs. The instructional show aired on Saturday mornings and had a strong following. The viewers of this would stay up all night on Fridays so they could be on the set the next morning, ready to return to the disco on Saturday night knowing with the latest personalized dance steps. The producers of the show, John Reid and Greg Roselli, routinely made appearances at disco functions with Robin and Reggie to scout out new dancing talent and promote upcoming events such as "Disco Night at White Sox Park". In Sacramento, California, Disco King Paul Dale Roberts danced for the Guinness Book of World Records. Roberts danced for 205 hours which is the equivalent of 8 ½ days. Other dance marathons took place after Roberts held the world's record for disco dancing for a short period of time. Some notable professional dance troupes of the 1970s included Pan's People and Hot Gossip. For many dancers, a key source of inspiration for 1970s disco dancing was the film Saturday Night Fever (1977). This developed into the music and dance style of such films as Fame (1980), Disco Dancer (1982), Flashdance (1983), and The Last Days of Disco (1998). Interest in disco dancing also helped spawn dance competition TV shows such as Dance Fever (1979). Fashion Disco fashions were very trendy in the late 1970s. Discothèque-goers often wore glamorous, expensive, and extravagant fashions for nights out at their local disco club. Some women would wear sheer, flowing dresses, such as Halston dresses or loose, flared pants. Other women wore tight, revealing, sexy clothes, such as backless halter tops, disco pants, "hot pants", or body-hugging spandex bodywear or "catsuits". Men would wear shiny polyester Qiana shirts with colorful patterns and pointy, extra wide collars, preferably open at the chest. Men often wore Pierre Cardin suits, three piece suits with a vest and double-knit polyester shirt jackets with matching trousers known as the leisure suit. Men's leisure suits were typically form-fitted in some parts of the body, such as the waist and bottom, but the lower part of the pants were flared in a bell bottom style, to permit freedom of movement. During the disco era, men engaged in elaborate grooming rituals and spent time choosing fashion clothing, both activities that would have been considered "feminine" according to the gender stereotypes of the era. Women dancers wore glitter makeup, sequins, or gold lamé clothing that would shimmer under the lights. Bold colors were popular for both genders. Platform shoes and boots for both genders and high heels for women were popular footwear. Necklaces and medallions were a common fashion accessory. Less commonly, some disco dancers wore outlandish costumes, dressed in drag, covered their bodies with gold or silver paint, or wore very skimpy outfits leaving them nearly nude; these uncommon get-ups were more likely to be seen at invitation-only New York City loft parties and disco clubs. Drug subculture In addition to the dance and fashion aspects of the disco club scene, there was also a thriving club drug subculture, particularly for drugs that would enhance the experience of dancing to the loud, bass-heavy music and the flashing colored lights, such as cocaine (nicknamed "blow"), amyl nitrite ("poppers"), and the "... other quintessential 1970s club drug Quaalude, which suspended motor coordination and gave the sensation that one's arms and legs had turned to 'Jell-O.'" Quaaludes were so popular at disco clubs that the drug was nicknamed "disco biscuits". Paul Gootenberg states that "[t]he relationship of cocaine to 1970s disco culture cannot be stressed enough..." During the 1970s, the use of cocaine by well-to-do celebrities led to its "glamorization" and to the widely held view that it was a "soft drug". LSD, marijuana, and "speed" (amphetamines) were also popular in disco clubs, and the use of these drugs "...contributed to the hedonistic quality of the dance floor experience." Since disco dances were typically held in liquor licensed-nightclubs and dance clubs, alcoholic drinks were also consumed by dancers; some users intentionally combined alcohol with the consumption of other drugs, such as Quaaludes, for a stronger effect. Eroticism and sexual liberation According to Peter Braunstein, the "massive quantities of drugs ingested in discothèques produced the next cultural phenomenon of the disco era: rampant promiscuity and public sex. While the dance floor was the central arena of seduction, actual sex usually took place in the nether regions of the disco: bathroom stalls, exit stairwells, and so on. In other cases the disco became a kind of 'main course' in a hedonist's menu for a night out." At The Saint nightclub, a high percentage of the gay male dancers and patrons would have sex in the club; they typically had unprotected sex, because in 1980, HIV-AIDS had not yet been identified. At The Saint, "dancers would elope to an un[monitored] upstairs balcony to engage in sex." The promiscuity and public sex at discos was part of a broader trend towards exploring a freer sexual expression in the 1970s, an era that is also associated with "swingers clubs, hot tubs, [and] key parties." In his paper, "In Defense of Disco" (1979), Richard Dyer claims eroticism as one of the three main characteristics of disco. As opposed to rock music which has a very phallic centered eroticism focusing on the sexual pleasure of men over other persons, Dyer describes disco as featuring a non-phallic full body eroticism. Through a range of percussion instruments, a willingness to play with rhythm, and the endless repeating of phrases without cutting the listener off, disco achieved this full body eroticism by restoring eroticism to the whole body for both sexes. This allowed for the potential expression of sexualities not defined by the cock/penis, and the erotic pleasure of bodies that are not defined by a relationship to a penis. The sexual liberation expressed through the rhythm of disco is further represented in the club spaces that disco grew within. In Peter Shapiro's Modulations: A History of Electronic Music: Throbbing Words on Sound, he discusses eroticism through the technology disco utilizes to create its audacious sound. The music, Shapiro states, is adjunct to "the pleasure-is-politics ethos of post-Stonewall culture." He explains how "mechano-eroticism," which links the technology used to create the unique mechanical sound of disco to eroticism, sets the genre in a new dimension of reality living outside of naturalism and heterosexuality. He uses Donna Summer's singles "Love to Love You Baby" (1975) and "I Feel Love" (1977) as examples of the ever present relationship between the synthesized bass lines and backgrounds to the simulated sounds of orgasms Summers echoes in the tracks, and likens them to the drug-fervent, sexually liberated fans of disco who sought to free themselves through disco's "aesthetic of machine sex." Shapiro sees this as an influence that creates sub-genres like hi-NRG and dub-disco, which allowed for eroticism and technology to be further explored through intense synth bass lines and alternative rhythmic techniques that tap into the entire body rather than the obvious erotic parts of the body. The New York nightclub The Sanctuary under resident DJ Francis Grasso is a prime example of this sexual liberty. In their history of the disc jockey and club culture, Bill Brewster and Frank Broughton describe the Sanctuary as "poured full of newly liberated gay men, then shaken (and stirred) by a weighty concoction of dance music and pharmacoia of pills and potions, the result is a festivaly of carnality." The Sanctuary was the "first totally uninhibited gay discotheque in America" and while sex was not allowed on the dancefloor, the dark corners, the bathrooms and the hallways of the adjacent buildings were all utilized for orgy like sexual engagements. By describing the music, drugs and liberated mentality as a trifecta coming together to create the festival of carnality, Brewster and Broughton are inciting all three as stimuli for the dancing, sex and other embodied movements that contributed to the corporeal vibrations within the Sanctuary. This supports the argument that the disco music took a role in facilitating this sexual liberation that was experienced in the discotheques. Further, this coupled with the recent legalization of abortions, the introduction of antibiotics and the pill all facilitated a culture shift around sex from one of procreation to pleasure and enjoyment fostering a very sex positive framework around discotheques. Given that at this time all instances of oral and anal gay sex were considered deviant and illegal acts in New York state, this sexual freedom can be considered quite liberatory and resistant to dominant oppressive structures. Further, in addition to gay sex being illegal in New York state, until 1973 the American Psychiatric Association classified homosexuality as an illness. This law and classification coupled together can be understood to have heavily dissuaded the expression of queerness in public, as such the liberatory dynamics of discotheques can be seen as having provided space for self-realization for queer persons. David Mancuso's club/house party, The Loft, was described as having a "pansexual attitude [that] was revolutionary in a country where up until recently it had been illegal for two men to dance together unless there was a woman present; where women were legally obliged to wear at least one recognizable item of female clothing in public; and where men visiting gay bars usually carried bail money with them." History 1940s–1960s: First discotheques Disco was mostly developed from music that was popular on the dance floor in clubs that started playing records instead of having a live band. The first discotheques mostly played swing music. Later on uptempo rhythm and blues became popular in American clubs and northern soul and glam rock records in the UK. In the early 1940s, nightclubs in Paris resorted to playing jazz records during the Nazi occupation. Régine Zylberberg claimed to have started the first discotheque and to have been the first club DJ in 1953 in the "Whisky à Go-Go" in Paris. She installed a dance floor with coloured lights and two turntables so she could play records without having a gap in the music. In October 1959, the owner of the Scotch Club in Aachen, West Germany chose to install a record player for the opening night instead of hiring a live band. The patrons were unimpressed until a young reporter, who happened to be covering the opening of the club, impulsively took control of the record player and introduced the records that he chose to play. Klaus Quirini later claimed to thus have been the world's first nightclub DJ. 1960s–1974: Precursors and early disco music During the 1960s, discotheque dancing became a European trend that was enthusiastically picked up by the American press. At this time, when the discotheque culture from Europe became popular in the United States, several music genres with danceable rhythms rose to popularity and evolved into different sub-genres: rhythm and blues (originated in the 1940s), soul (late 1950s and 1960s), funk (mid-1960s) and go-go (mid-1960s and 1970s; more than "disco", the word "go-go" originally indicated a music club). Those genres, mainly African-American ones, would influence much of early disco music. Also during the 1960s, the Motown record label developed the popular and influential Motown sound, described as having "1) simply structured songs with sophisticated melodies and chord changes, 2) a relentless four-beat drum pattern, 3) a gospel use of background voices, vaguely derived from the style of the Impressions, 4) a regular and sophisticated use of both horns and strings, 5) lead singers who were half way between pop and gospel music, 6) a group of accompanying musicians who were among the most dextrous, knowledgeable, and brilliant in all of popular music (Motown bassists have long been the envy of white rock bassists) and 7) a trebly style of mixing that relied heavily on electronic limiting and equalizing (boosting the high range frequencies) to give the overall product a distinctive sound, particularly effective for broadcast over AM radio." Motown had many hits with early disco elements by acts like the Supremes (for instance "You Keep Me Hangin' On" in 1966), Stevie Wonder (for instance "Superstition" in 1972), The Jackson 5 and Eddie Kendricks ("Keep on Truckin'" in 1973). At the end of the 1960s, musicians and audiences from the Black, Italian and Latino communities adopted several traits from the hippie and psychedelia subcultures. They included using music venues with a loud, overwhelming sound, free-form dancing, trippy lighting, colorful costumes, and the use of hallucinogenic drugs.(1998) "The Cambridge History of American Music", , , p.372: "Initially, disco musicians and audiences alike belonged to marginalized communities: women, gay, black, and Latinos" In addition, the perceived positivity, lack of irony, and earnestness of the hippies informed proto-disco music like MFSB's album Love Is the Message."But the pre-Saturday Night Fever dance underground was actually sweetly earnest and irony-free in its hippie-dippie positivity, as evinced by anthems like MFSB's Love Is the Message." – Village Voice, July 10, 2001. Partly through the success of Jimi Hendrix, psychedelic elements that were popular in rock music of the late 1960s found their way into soul and early funk music and formed the subgenre psychedelic soul. Examples can be found in the music of the Chambers Brothers, George Clinton with his Parliament-Funkadelic collective, Sly and the Family Stone and the productions of Norman Whitfield with The Temptations. The long instrumental introductions and detailed orchestration found in psychedelic soul tracks by the Temptations are also considered as cinematic soul. In the early 1970s, Curtis Mayfield and Isaac Hayes scored hits with cinematic soul songs that were actually composed for movie soundtracks: "Superfly" (1972) and "Theme from Shaft" (1971). The latter is sometimes regarded as an early disco song. From the mid-1960s to early 1970s, Philadelphia soul and New York soul developed as sub-genres that also had lavish percussion, lush string orchestra arrangements, and expensive record production processes. In the early 1970s, the Philly soul productions by Gamble and Huff evolved from the simpler arrangements of the late-1960s into a style featuring lush strings, thumping basslines, and sliding hi-hat rhythms. These elements would become typical for disco music and are found in several of the hits they produced in the early 1970s: "Love Train" by the O'Jays (with M.F.S.B. as the backup band) was released in 1972 and topped the Billboard Hot 100 in March 1973 "The Love I Lost" by Harold Melvin & the Blue Notes (1973) "Now That We Found Love" by The O'Jays (1973), later a hit for Third World in 1978. "TSOP (The Sound of Philadelphia)" by MFSB with vocals by The Three Degrees, a wordless song written as the theme for Soul Train and a #1 hit on the Billboard Hot 100 in 1974. Other early disco tracks that helped shape disco and became popular on the dance floors of (underground) discotheque clubs and parties include: "Soul Makossa" by Manu Dibango was first released in France in 1972. It was picked up by the underground disco scene in New York and subsequently got a proper release in the U.S., reaching #35 on the Billboard Hot 100 in 1973. "The Night" by the Four Seasons was released in 1972, but was not immediately popular. It appealed to the Northern soul scene and became a hit in the UK in 1975. "Love's Theme" by the Love Unlimited Orchestra conducted by Barry White, an instrumental song originally featured on Under the Influence of... Love Unlimited in July 1973 from which it was culled as a single in November of that year. Subsequently the conductor included it on his own debut album Rhapsody in White (1974) where the track reached number one on the Billboard Hot 100 early that year. "Jungle Fever" by The Chakachas was first released in Belgium in 1971, was later released in the U.S. in 1972, where it reached #8 on the Billboard Hot 100 that same year. "Girl You Need a Change of Mind" by Eddie Kendricks was released in May 1972, on the album People ... Hold On. Early disco was dominated by record producers and labels such as Salsoul Records (Ken, Stanley, and Joseph Cayre), West End Records (Mel Cheren), Casablanca (Neil Bogart), and Prelude (Marvin Schlachter), to name a few. The genre was also shaped by Tom Moulton, who wanted to extend the enjoyment of dance songs — thus creating the extended mix or "remix", going from a three-minute 45 rpm single to the much longer 12" record. Other influential DJs and remixers who helped to establish what became known as the "disco sound" included David Mancuso, Nicky Siano, Shep Pettibone, Larry Levan, Walter Gibbons, and Chicago-based Frankie Knuckles. Frankie Knuckles was not only an important disco DJ; he also helped to develop house music in the 1980s. Disco hit the television airwaves as part of the music/dance variety show Soul Train in 1971 hosted by Don Cornelius, then Marty Angelo's Disco Step-by-Step Television Show in 1975, Steve Marcus' Disco Magic/Disco 77, Eddie Rivera's Soap Factory, and Merv Griffin's Dance Fever, hosted by Deney Terrio, who is credited with teaching actor John Travolta to dance for his role in the film Saturday Night Fever, as well as DANCE, based out of Columbia, South Carolina. In 1974, New York City's WPIX-FM premiered the first disco radio show. Early disco culture in the United States In the 1970s, the key counterculture of the 1960s, the hippie movement, was fading away. The economic prosperity of the previous decade had declined, and unemployment, inflation and crime rates had soared. Political issues like the backlash from the Civil Rights Movement culminating in the form of race riots, the Vietnam War, the assassinations of Dr. Martin Luther King Jr. and John F. Kennedy, and the Watergate scandal, left many feeling disillusioned and hopeless. The start of the '70s was marked by a shift in the consciousness of the American people: the rise of the feminist movement, identity politics, gangs, etc. very much shaped this era. Disco music and disco dancing provided an escape from negative social and economic issues. The non-partnered dance style of disco music allowed people of all races and sexual orientations to enjoy the dancefloor atmosphere. In Beautiful Things in Popular Culture, Simon Frith highlights the sociability of disco and its roots in 1960s counterculture. "The driving force of the New York underground dance scene in which disco was forged was not simply that city's complex ethnic and sexual culture but also a 1960s notion of community, pleasure and generosity that can only be described as hippie", he says. "The best disco music contained within it a remarkably powerful sense of collective euphoria." The birth of disco is often claimed to be found in the private dance parties held by New York City DJ David Mancuso's home that became known as The Loft, an invitation-only non-commercial underground club that inspired many others. He organized the first major party in his Manhattan home on Valentine's Day 1970 with the name "Love Saves The Day". After some months the parties became weekly events and Mancuso continued to give regular parties into the 1990s. Mancuso required that the music played had to be soulful, rhythmic, and impart words of hope, redemption, or pride. When Mancuso threw his first informal house parties, the gay community (which made up much of The Loft's attendee roster) was often harassed in the gay bars and dance clubs, with many gay men carrying bail money with them to gay bars. But at The Loft and many other early, private discotheques, they could dance together without fear of police action thanks to Mancuso's underground, yet legal, policies. Vince Aletti described it "like going to party, completely mixed, racially and sexually, where there wasn't any sense of someone being more important than anyone else," and Alex Rosner reiterated this saying "It was probably about sixty percent black and seventy percent gay...There was a mix of sexual orientation, there was a mix of races, mix of economic groups. A real mix, where the common denominator was music." Film critic Roger Ebert called the popular embrace of disco's exuberant dance moves an escape from "the general depression and drabness of the political and musical atmosphere of the late seventies." Pauline Kael, writing about the disco-themed film Saturday Night Fever, said the film and disco itself touched on "something deeply romantic, the need to move, to dance, and the need to be who you'd like to be. Nirvana is the dance; when the music stops, you return to being ordinary." Early disco culture in the United Kingdom In the late 1960s, uptempo soul with heavy beats and some associated dance styles and fashion were picked up in the British mod scene and formed the northern soul movement. Originating at venues such as the Twisted Wheel in Manchester, it quickly spread to other UK dancehalls and nightclubs like the Chateau Impney (Droitwich Spa|Droitwich]]), Catacombs (Wolverhampton), the Highland Rooms at Blackpool Mecca, Golden Torch (Stoke-on-Trent) and Wigan Casino. As the favoured beat became more uptempo and frantic in the early 1970s, northern soul dancing became more athletic, somewhat resembling the later dance styles of disco and break dancing. Featuring spins, flips, karate kicks and backdrops, club dancing styles were often inspired by the stage performances of touring American soul acts such as Little Anthony & the Imperials and Jackie Wilson. In 1974, there were an estimated 25,000 mobile discos and 40,000 professional disc jockeys in the United Kingdom. Mobile discos were hired deejays that brought their own equipment to provide music for special events. Glam rock tracks were popular, with, for example, Gary Glitter's 1972 single "Rock and Roll Part 2" becoming popular on UK dance floors while it did not get much radio airplay. 1974–1977: Rise to mainstream From 1974 to 1977, disco music increased in popularity as many disco songs topped the charts. The Hues Corporation's "Rock the Boat" (1974), a US number-one single and million-seller, was one of the early disco songs to reach number one. The same year saw the release of "Kung Fu Fighting", performed by Carl Douglas and produced by Biddu, which reached number one in both the UK and US, and became the best-selling single of the year and one of the best-selling singles of all time with 11 million records sold worldwide, helping to popularize disco to a great extent. Another notable disco success that year was George McCrae's "Rock Your Baby": it became the United Kingdom's first number one chart disco single. In the northwestern sections of the United Kingdom, the northern soul explosion, which started in the late 1960s and peaked in 1974, made the region receptive to disco, which the region's disc jockeys were bringing back from New York City. The shift by some DJs to the newer sounds coming from the U.S.A. resulted in a split in the scene, whereby some abandoned the 1960s soul and pushed a modern soul sound which tended to be more closely aligned with disco than soul. In 1975, Gloria Gaynor released her first side-long vinyl album, which included a remake of the Jackson 5's "Never Can Say Goodbye" (which, in fact, is also the album title) and two other songs, "Honey Bee" and her disco version of "Reach Out (I'll Be There)", first topped the Billboard disco/dance charts in November 1974. Later in 1978, Gaynor's number-one disco song was "I Will Survive", which was seen as a symbol of female strength and a gay anthem, like her further disco hit, a 1983 remake of "I Am What I Am"; in 1979 she released "Let Me Know (I Have a Right)", a single which gained popularity in the civil rights movements. Also in 1975, Vincent Montana Jr.'s Salsoul Orchestra contributed with their Latin-flavored orchestral dance song "Salsoul Hustle", reaching number four on the Billboard Dance Chart and their 1976 hits "Tangerine" and "Nice 'n' Naasty", the first being a cover of a 1941 song. Songs such as Van McCoy's 1975 "The Hustle" and the humorous Joe Tex 1977 "Ain't Gonna Bump No More (With No Big Fat Woman)" gave names to the popular disco dances "the Bump" and "the Hustle". Other notable early successful disco songs include Barry White's "You're the First, the Last, My Everything" (1974), Labelle's "Lady Marmalade" (1974), Disco-Tex and the Sex-O-Lettes' "Get Dancin'" (1974), Silver Convention's "Fly, Robin, Fly" (1975) and "Get Up and Boogie" (1976) and Johnny Taylor's "Disco Lady" (1976). Formed by Harry Wayne Casey (a.k.a. "KC") and Richard Finch, Miami's KC and the Sunshine Band had a string of disco-definitive top-five singles between 1975 and 1977, including "Get Down Tonight", "That's the Way (I Like It)", "(Shake, Shake, Shake) Shake Your Booty", "I'm Your Boogie Man" and "Keep It Comin' Love". In this period, rock bands like the English Electric Light Orchestra featured in their songs a violin sound that became a staple of disco music, as in the 1975 hit "Evil Woman", although the genre was correctly described as orchestral rock. Other disco producers such as Tom Moulton took ideas and techniques from dub music (which came with the increased Jamaican migration to New York City in the 1970s) to provide alternatives to the "four on the floor" style that dominated. DJ Larry Levan utilized styles from dub and jazz and remixing techniques to create early versions of house music that sparked the genre. Motown turning disco Norman Whitfield was an influential producer and songwriter at Motown records, renowned for creating innovative "psychedelic soul" songs with many hits for Marvin Gaye, the Velvelettes, the Temptations and Gladys Knight & The Pips. From around the production of the Temptations' album Cloud Nine in 1968, he incorporated some psychedelic influences and started to produce longer, dance-friendly tracks, with more room for elaborate rhythmic instrumental parts. An example of such a long psychedelic soul track is "Papa Was a Rollin' Stone", which appeared as a single edit of almost seven minutes and an approximately 12-minute-long 12" version in 1972. By the early 70s, many of Whitfield's productions evolved more and more towards funk and disco, as heard on albums by the Undisputed Truth and the 1973 album G.I.T.: Get It Together by The Jackson 5. The Undisputed Truth, a Motown recording act assembled by Whitfield to experiment with his psychedelic soul production techniques, found success with their 1971 song "Smiling Faces Sometimes". Their disco single "You + Me = Love" (number 43) was produced by Whitfield and made number 2 on the US Dance Charts in 1976. In 1975, Whitfield left Motown and founded his own label Whitfield records, on which also "You + Me = Love" was released. Whitfield produced some more disco hits, including "Car Wash" (1976) by Rose Royce from the album soundtrack to the 1976 film Car Wash. In 1977, singer, songwriter and producer Willie Hutch, who had been signed to Motown since 1970, now signed with Whitfield's new label, and scored a successful disco single with his song "In and Out" in 1982. Other Motown artists turned to disco as well. Diana Ross embraced the disco sound with her successful 1976 outing "Love Hangover" from her self-titled album. Her 1980 dance classics "Upside Down" and "I'm Coming Out" were written and produced by Nile Rodgers and Bernard Edwards of the group Chic. The Supremes, the group that made Ross famous, scored a handful of hits in the disco clubs without her, most notably 1976's "I'm Gonna Let My Heart Do the Walking" and, their last charted single before disbanding, 1977's "You're My Driving Wheel". At the request of Motown that he produce songs in the disco genre, Marvin Gaye released "Got to Give It Up" in 1978, despite his dislike of disco. He vowed not to record any songs in the genre, and actually wrote the song as a parody. However, several of Gaye's songs have disco elements, including "I Want You" (1975). Stevie Wonder released the disco single "Sir Duke" in 1977 as a tribute to Duke Ellington, the influential jazz legend who had died in 1974. Smokey Robinson left the Motown group the Miracles for a solo career in 1972 and released his third solo album A Quiet Storm in 1975, which spawned and lent its name to the "Quiet Storm" musical programming format and subgenre of R&B. It contained the disco single "Baby That's Backatcha". Other Motown artists who scored disco hits include: Robinson's former group, the Miracles, with "Love Machine" (1975), Eddie Kendricks with "Keep On Truckin'" (1973), the Originals with "Down to Love Town" (1976) and Thelma Houston with her cover of the Harold Melvin and the Blue Notes song "Don't Leave Me This Way" (1976). The label continued to release successful songs into the 1980s with Rick James' "Super Freak" (1981), and the Commodores' "Lady (You Bring Me Up)" (1981). Several of Motown's solo artists who left the label went on to have successful disco songs. Mary Wells, Motown's first female superstar with her signature song "My Guy" (written by Smokey Robinson), abruptly left the label in 1964. She briefly reappeared on the charts with the disco song "Gigolo" in 1980. Jimmy Ruffin, the elder brother of the Temptations lead singer David Ruffin, was also signed to Motown, and released his most successful and well-known song "What Becomes of the Brokenhearted" as a single in 1966. Ruffin eventually left the record label in the mid-1970s, but saw success with the 1980 disco song "Hold On (To My Love)", which was written and produced by Robin Gibb of the Bee Gees, for his album Sunrise. Edwin Starr, known for his Motown protest song "War" (1970), reentered the charts in 1979 with a pair of disco songs, "Contact" and "H.A.P.P.Y. Radio". Kiki Dee became the first white British singer to sign with Motown in the US, and released one album, Great Expectations (1970), and two singles "The Day Will Come Between Sunday and Monday" (1970) and "Love Makes the World Go Round" (1971), the latter giving her first-ever chart entry (number 87 on the US Chart). She soon left the company and signed with Elton John's The Rocket Record Company, and in 1976 had her biggest and best-known single, "Don't Go Breaking My Heart", a disco duet with John. The song was intended as an affectionate disco-style pastiche of the Motown sound, in particular the various duets recorded by Marvin Gaye with Tammi Terrell and Kim Weston. Many Motown groups who had left the record label charted with disco songs. The Jackson 5, one of Motown's premier acts in the early 1970s, left the record company in 1975 (Jermaine Jackson, however, remained with the label) after successful songs like "I Want You Back" (1969) and "ABC" (1970), and even the disco song "Dancing Machine" (1974). Renamed as 'the Jacksons' (as Motown owned the name 'the Jackson 5'), they went on to find success with disco songs like "Blame It on the Boogie" (1978), "Shake Your Body (Down to the Ground)" (1979) and "Can You Feel It?" (1981) on the Epic label. The Isley Brothers, whose short tenure at the company had produced the song "This Old Heart of Mine (Is Weak for You)" in 1966, went on release successful disco songs like "That Lady" (1973) and "It's a Disco Night (Rock Don't Stop)" (1979). Gladys Knight and the Pips, who recorded the most successful version of "I Heard It Through the Grapevine" (1967) before Marvin Gaye, scored commercially successful singles such as "Baby, Don't Change Your Mind" (1977) and "Bourgie, Bourgie" (1980) in the disco era. The Detroit Spinners were also signed to the Motown label and saw success with the Stevie Wonder-produced song "It's a Shame" in 1970. They left soon after, on the advice of fellow Detroit native Aretha Franklin, to Atlantic Records, and there had disco songs like "The Rubberband Man" (1976). In 1979, they released a successful cover of Elton John's "Are You Ready for Love", as well as a medley of the Four Seasons' song "Working My Way Back to You" and Michael Zager's "Forgive Me, Girl". The Four Seasons themselves were briefly signed to Motown's MoWest label, a short-lived subsidiary for R&B and soul artists based on the West Coast, and there the group produced one album, Chameleon (1972) – to little commercial success in the US. However, one single, "The Night", was released in Britain in 1975, and thanks to popularity from the Northern Soul circuit, reached number seven on the UK Singles Chart. The Four Seasons left Motown in 1974 and went on to have a disco hit with their song "December, 1963 (Oh, What a Night)" (1975) for Warner Curb Records. Eurodisco By far the most successful Euro disco act was ABBA (1972–1982). This Swedish quartet, which sang primarily in English, found success with singles such as "Waterloo" (1974), "Fernando" (1976), "Take a Chance on Me" (1978), "Gimme! Gimme! Gimme! (A Man After Midnight)" (1979), and their signature smash hit "Dancing Queen" (1976)—ranks as the Fourth best-selling act of all time. In 1970s Munich, West Germany, music producers Giorgio Moroder and Pete Bellotte made a decisive contribution to disco music with a string of hits for Donna Summer, which became known as the "Munich Sound". In 1975, Summer suggested the lyric "Love to Love You Baby" to Moroder and Bellotte, who turned the lyric into a full disco song. The final product, which contained the vocalizations of a series of simulated orgasms, initially was not intended for release, but when Moroder played it in the clubs it caused a sensation and he released it. The song became an international hit, reaching the charts in many European countries and the US (No. 2). It has been described as the arrival of the expression of raw female sexual desire in pop music. A 17-minute 12-inch single was released. The 12" single became and remains a standard in discos today. In 1976 Donna Summer's version of "Could It Be Magic" brought disco further into the mainstream. In 1977 Summer, Moroder and Bellotte further released "I Feel Love", as the B-side of "Can't We Just Sit Down (And Talk It Over)", which revolutionized dance music with its mostly electronic production and was a massive worldwide success, spawning the Hi-NRG subgenre. Giorgio Moroder was described by AllMusic as "one of the principal architects of the disco sound". Another successful disco music project by Moroder at that time was Munich Machine (1976–1980). Boney M. (1974–1986) was a West German disco group of four West Indian singers and dancers masterminded by record producer Frank Farian. Boney M. charted worldwide with such songs as "Daddy Cool" (1976) "Ma Baker" (1977) and "Rivers Of Babylon" (1978). Another successful West German disco recording act was Silver Convention (1974–1979). The German group Kraftwerk also had an influence on Euro disco. In France, Dalida released "J'attendrai" ("I Will Wait") in 1975, which also became successful in Canada, Europe and Japan. Dalida successfully adjusted herself to disco era and released at least a dozen of songs that charted among top number 10 in whole Europe and wider. Claude François, who re-invented himself as the king of French disco, released "La plus belle chose du monde", a French version of the Bee Gees song "Massachusetts", which became successful in Canada and Europe and "Alexandrie Alexandra" was posthumously released on the day of his burial and became a worldwide success. Cerrone's early songs, "Love in C Minor" (1976), "Supernature" (1977) and "Give Me Love" (1978) were successful in the US and Europe. Another Euro disco act was the French diva Amanda Lear, where Euro disco sound is most heard in "Enigma (Give a Bit of Mmh to Me)" (1978). French producer Alec Costandinos assembled the disco group Love and Kisses (1977–1982). In Italy Raffaella Carrà is the most successful disco act, alongside La Bionda, Hermanas Goggi and Oliver Onions. Her greatest international single was "Tanti Auguri" ("Best Wishes"), which has become a popular song with gay audiences. The song is also known under its Spanish title "Para hacer bien el amor hay que venir al sur" (which refers to Southern Europe, since the song was recorded and taped in Spain). The Estonian version of the song "Jätke võtmed väljapoole" was performed by Anne Veski. "A far l'amore comincia tu" ("To make love, your move first") was another success for her internationally, known in Spanish as "En el amor todo es empezar", in German as "Liebelei", in French as "Puisque tu l'aimes dis le lui", and in English as "Do It, Do It Again". It was her only entry | Some DJs were also record producers who created and produced disco songs in the recording studio. Larry Levan, for example, was a prolific record producer as well as a DJ. Because record sales were often dependent on dance floor play by DJs in leading nightclubs, DJs were also influential for the development and popularization of certain types of disco music being produced for record labels. Dance In the early years, dancers in discos danced in a "hang loose" or "freestyle" approach. At first, many dancers improvised their own dance styles and dance steps. Later in the disco era, popular dance styles were developed, including the "Bump", "Penguin", "Boogaloo", "Watergate" and "Robot". By October 1975 the Hustle reigned. It was highly stylized, sophisticated and overtly sexual. Variations included the Brooklyn Hustle, New York Hustle and Latin Hustle. During the disco era, many nightclubs would commonly host disco dance competitions or offer free dance lessons. Some cities had disco dance instructors or dance schools, which taught people how to do popular disco dances such as "touch dancing", "the hustle", and "the cha cha". The pioneer of disco dance instruction was Karen Lustgarten in San Francisco in 1973. Her book The Complete Guide to Disco Dancing (Warner Books 1978) was the first to name, break down and codify popular disco dances as dance forms and distinguish between disco freestyle, partner and line dances. The book topped the New York Times bestseller list for 13 weeks and was translated into Chinese, German and French. In Chicago, the Step By Step disco dance TV show was launched with the sponsorship support of the Coca-Cola company. Produced in the same studio that Don Cornelius used for the nationally syndicated dance/music television show, Soul Train, Step by Step'''s audience grew and the show became a success. The dynamic dance duo of Robin and Reggie led the show. The pair spent the week teaching disco dancing to dancers in the disco clubs. The instructional show aired on Saturday mornings and had a strong following. The viewers of this would stay up all night on Fridays so they could be on the set the next morning, ready to return to the disco on Saturday night knowing with the latest personalized dance steps. The producers of the show, John Reid and Greg Roselli, routinely made appearances at disco functions with Robin and Reggie to scout out new dancing talent and promote upcoming events such as "Disco Night at White Sox Park". In Sacramento, California, Disco King Paul Dale Roberts danced for the Guinness Book of World Records. Roberts danced for 205 hours which is the equivalent of 8 ½ days. Other dance marathons took place after Roberts held the world's record for disco dancing for a short period of time. Some notable professional dance troupes of the 1970s included Pan's People and Hot Gossip. For many dancers, a key source of inspiration for 1970s disco dancing was the film Saturday Night Fever (1977). This developed into the music and dance style of such films as Fame (1980), Disco Dancer (1982), Flashdance (1983), and The Last Days of Disco (1998). Interest in disco dancing also helped spawn dance competition TV shows such as Dance Fever (1979). Fashion Disco fashions were very trendy in the late 1970s. Discothèque-goers often wore glamorous, expensive, and extravagant fashions for nights out at their local disco club. Some women would wear sheer, flowing dresses, such as Halston dresses or loose, flared pants. Other women wore tight, revealing, sexy clothes, such as backless halter tops, disco pants, "hot pants", or body-hugging spandex bodywear or "catsuits". Men would wear shiny polyester Qiana shirts with colorful patterns and pointy, extra wide collars, preferably open at the chest. Men often wore Pierre Cardin suits, three piece suits with a vest and double-knit polyester shirt jackets with matching trousers known as the leisure suit. Men's leisure suits were typically form-fitted in some parts of the body, such as the waist and bottom, but the lower part of the pants were flared in a bell bottom style, to permit freedom of movement. During the disco era, men engaged in elaborate grooming rituals and spent time choosing fashion clothing, both activities that would have been considered "feminine" according to the gender stereotypes of the era. Women dancers wore glitter makeup, sequins, or gold lamé clothing that would shimmer under the lights. Bold colors were popular for both genders. Platform shoes and boots for both genders and high heels for women were popular footwear. Necklaces and medallions were a common fashion accessory. Less commonly, some disco dancers wore outlandish costumes, dressed in drag, covered their bodies with gold or silver paint, or wore very skimpy outfits leaving them nearly nude; these uncommon get-ups were more likely to be seen at invitation-only New York City loft parties and disco clubs. Drug subculture In addition to the dance and fashion aspects of the disco club scene, there was also a thriving club drug subculture, particularly for drugs that would enhance the experience of dancing to the loud, bass-heavy music and the flashing colored lights, such as cocaine (nicknamed "blow"), amyl nitrite ("poppers"), and the "... other quintessential 1970s club drug Quaalude, which suspended motor coordination and gave the sensation that one's arms and legs had turned to 'Jell-O.'" Quaaludes were so popular at disco clubs that the drug was nicknamed "disco biscuits". Paul Gootenberg states that "[t]he relationship of cocaine to 1970s disco culture cannot be stressed enough..." During the 1970s, the use of cocaine by well-to-do celebrities led to its "glamorization" and to the widely held view that it was a "soft drug". LSD, marijuana, and "speed" (amphetamines) were also popular in disco clubs, and the use of these drugs "...contributed to the hedonistic quality of the dance floor experience." Since disco dances were typically held in liquor licensed-nightclubs and dance clubs, alcoholic drinks were also consumed by dancers; some users intentionally combined alcohol with the consumption of other drugs, such as Quaaludes, for a stronger effect. Eroticism and sexual liberation According to Peter Braunstein, the "massive quantities of drugs ingested in discothèques produced the next cultural phenomenon of the disco era: rampant promiscuity and public sex. While the dance floor was the central arena of seduction, actual sex usually took place in the nether regions of the disco: bathroom stalls, exit stairwells, and so on. In other cases the disco became a kind of 'main course' in a hedonist's menu for a night out." At The Saint nightclub, a high percentage of the gay male dancers and patrons would have sex in the club; they typically had unprotected sex, because in 1980, HIV-AIDS had not yet been identified. At The Saint, "dancers would elope to an un[monitored] upstairs balcony to engage in sex." The promiscuity and public sex at discos was part of a broader trend towards exploring a freer sexual expression in the 1970s, an era that is also associated with "swingers clubs, hot tubs, [and] key parties." In his paper, "In Defense of Disco" (1979), Richard Dyer claims eroticism as one of the three main characteristics of disco. As opposed to rock music which has a very phallic centered eroticism focusing on the sexual pleasure of men over other persons, Dyer describes disco as featuring a non-phallic full body eroticism. Through a range of percussion instruments, a willingness to play with rhythm, and the endless repeating of phrases without cutting the listener off, disco achieved this full body eroticism by restoring eroticism to the whole body for both sexes. This allowed for the potential expression of sexualities not defined by the cock/penis, and the erotic pleasure of bodies that are not defined by a relationship to a penis. The sexual liberation expressed through the rhythm of disco is further represented in the club spaces that disco grew within. In Peter Shapiro's Modulations: A History of Electronic Music: Throbbing Words on Sound, he discusses eroticism through the technology disco utilizes to create its audacious sound. The music, Shapiro states, is adjunct to "the pleasure-is-politics ethos of post-Stonewall culture." He explains how "mechano-eroticism," which links the technology used to create the unique mechanical sound of disco to eroticism, sets the genre in a new dimension of reality living outside of naturalism and heterosexuality. He uses Donna Summer's singles "Love to Love You Baby" (1975) and "I Feel Love" (1977) as examples of the ever present relationship between the synthesized bass lines and backgrounds to the simulated sounds of orgasms Summers echoes in the tracks, and likens them to the drug-fervent, sexually liberated fans of disco who sought to free themselves through disco's "aesthetic of machine sex." Shapiro sees this as an influence that creates sub-genres like hi-NRG and dub-disco, which allowed for eroticism and technology to be further explored through intense synth bass lines and alternative rhythmic techniques that tap into the entire body rather than the obvious erotic parts of the body. The New York nightclub The Sanctuary under resident DJ Francis Grasso is a prime example of this sexual liberty. In their history of the disc jockey and club culture, Bill Brewster and Frank Broughton describe the Sanctuary as "poured full of newly liberated gay men, then shaken (and stirred) by a weighty concoction of dance music and pharmacoia of pills and potions, the result is a festivaly of carnality." The Sanctuary was the "first totally uninhibited gay discotheque in America" and while sex was not allowed on the dancefloor, the dark corners, the bathrooms and the hallways of the adjacent buildings were all utilized for orgy like sexual engagements. By describing the music, drugs and liberated mentality as a trifecta coming together to create the festival of carnality, Brewster and Broughton are inciting all three as stimuli for the dancing, sex and other embodied movements that contributed to the corporeal vibrations within the Sanctuary. This supports the argument that the disco music took a role in facilitating this sexual liberation that was experienced in the discotheques. Further, this coupled with the recent legalization of abortions, the introduction of antibiotics and the pill all facilitated a culture shift around sex from one of procreation to pleasure and enjoyment fostering a very sex positive framework around discotheques. Given that at this time all instances of oral and anal gay sex were considered deviant and illegal acts in New York state, this sexual freedom can be considered quite liberatory and resistant to dominant oppressive structures. Further, in addition to gay sex being illegal in New York state, until 1973 the American Psychiatric Association classified homosexuality as an illness. This law and classification coupled together can be understood to have heavily dissuaded the expression of queerness in public, as such the liberatory dynamics of discotheques can be seen as having provided space for self-realization for queer persons. David Mancuso's club/house party, The Loft, was described as having a "pansexual attitude [that] was revolutionary in a country where up until recently it had been illegal for two men to dance together unless there was a woman present; where women were legally obliged to wear at least one recognizable item of female clothing in public; and where men visiting gay bars usually carried bail money with them." History 1940s–1960s: First discotheques Disco was mostly developed from music that was popular on the dance floor in clubs that started playing records instead of having a live band. The first discotheques mostly played swing music. Later on uptempo rhythm and blues became popular in American clubs and northern soul and glam rock records in the UK. In the early 1940s, nightclubs in Paris resorted to playing jazz records during the Nazi occupation. Régine Zylberberg claimed to have started the first discotheque and to have been the first club DJ in 1953 in the "Whisky à Go-Go" in Paris. She installed a dance floor with coloured lights and two turntables so she could play records without having a gap in the music. In October 1959, the owner of the Scotch Club in Aachen, West Germany chose to install a record player for the opening night instead of hiring a live band. The patrons were unimpressed until a young reporter, who happened to be covering the opening of the club, impulsively took control of the record player and introduced the records that he chose to play. Klaus Quirini later claimed to thus have been the world's first nightclub DJ. 1960s–1974: Precursors and early disco music During the 1960s, discotheque dancing became a European trend that was enthusiastically picked up by the American press. At this time, when the discotheque culture from Europe became popular in the United States, several music genres with danceable rhythms rose to popularity and evolved into different sub-genres: rhythm and blues (originated in the 1940s), soul (late 1950s and 1960s), funk (mid-1960s) and go-go (mid-1960s and 1970s; more than "disco", the word "go-go" originally indicated a music club). Those genres, mainly African-American ones, would influence much of early disco music. Also during the 1960s, the Motown record label developed the popular and influential Motown sound, described as having "1) simply structured songs with sophisticated melodies and chord changes, 2) a relentless four-beat drum pattern, 3) a gospel use of background voices, vaguely derived from the style of the Impressions, 4) a regular and sophisticated use of both horns and strings, 5) lead singers who were half way between pop and gospel music, 6) a group of accompanying musicians who were among the most dextrous, knowledgeable, and brilliant in all of popular music (Motown bassists have long been the envy of white rock bassists) and 7) a trebly style of mixing that relied heavily on electronic limiting and equalizing (boosting the high range frequencies) to give the overall product a distinctive sound, particularly effective for broadcast over AM radio." Motown had many hits with early disco elements by acts like the Supremes (for instance "You Keep Me Hangin' On" in 1966), Stevie Wonder (for instance "Superstition" in 1972), The Jackson 5 and Eddie Kendricks ("Keep on Truckin'" in 1973). At the end of the 1960s, musicians and audiences from the Black, Italian and Latino communities adopted several traits from the hippie and psychedelia subcultures. They included using music venues with a loud, overwhelming sound, free-form dancing, trippy lighting, colorful costumes, and the use of hallucinogenic drugs.(1998) "The Cambridge History of American Music", , , p.372: "Initially, disco musicians and audiences alike belonged to marginalized communities: women, gay, black, and Latinos" In addition, the perceived positivity, lack of irony, and earnestness of the hippies informed proto-disco music like MFSB's album Love Is the Message."But the pre-Saturday Night Fever dance underground was actually sweetly earnest and irony-free in its hippie-dippie positivity, as evinced by anthems like MFSB's Love Is the Message." – Village Voice, July 10, 2001. Partly through the success of Jimi Hendrix, psychedelic elements that were popular in rock music of the late 1960s found their way into soul and early funk music and formed the subgenre psychedelic soul. Examples can be found in the music of the Chambers Brothers, George Clinton with his Parliament-Funkadelic collective, Sly and the Family Stone and the productions of Norman Whitfield with The Temptations. The long instrumental introductions and detailed orchestration found in psychedelic soul tracks by the Temptations are also considered as cinematic soul. In the early 1970s, Curtis Mayfield and Isaac Hayes scored hits with cinematic soul songs that were actually composed for movie soundtracks: "Superfly" (1972) and "Theme from Shaft" (1971). The latter is sometimes regarded as an early disco song. From the mid-1960s to early 1970s, Philadelphia soul and New York soul developed as sub-genres that also had lavish percussion, lush string orchestra arrangements, and expensive record production processes. In the early 1970s, the Philly soul productions by Gamble and Huff evolved from the simpler arrangements of the late-1960s into a style featuring lush strings, thumping basslines, and sliding hi-hat rhythms. These elements would become typical for disco music and are found in several of the hits they produced in the early 1970s: "Love Train" by the O'Jays (with M.F.S.B. as the backup band) was released in 1972 and topped the Billboard Hot 100 in March 1973 "The Love I Lost" by Harold Melvin & the Blue Notes (1973) "Now That We Found Love" by The O'Jays (1973), later a hit for Third World in 1978. "TSOP (The Sound of Philadelphia)" by MFSB with vocals by The Three Degrees, a wordless song written as the theme for Soul Train and a #1 hit on the Billboard Hot 100 in 1974. Other early disco tracks that helped shape disco and became popular on the dance floors of (underground) discotheque clubs and parties include: "Soul Makossa" by Manu Dibango was first released in France in 1972. It was picked up by the underground disco scene in New York and subsequently got a proper release in the U.S., reaching #35 on the Billboard Hot 100 in 1973. "The Night" by the Four Seasons was released in 1972, but was not immediately popular. It appealed to the Northern soul scene and became a hit in the UK in 1975. "Love's Theme" by the Love Unlimited Orchestra conducted by Barry White, an instrumental song originally featured on Under the Influence of... Love Unlimited in July 1973 from which it was culled as a single in November of that year. Subsequently the conductor included it on his own debut album Rhapsody in White (1974) where the track reached number one on the Billboard Hot 100 early that year. "Jungle Fever" by The Chakachas was first released in Belgium in 1971, was later released in the U.S. in 1972, where it reached #8 on the Billboard Hot 100 that same year. "Girl You Need a Change of Mind" by Eddie Kendricks was released in May 1972, on the album People ... Hold On. Early disco was dominated by record producers and labels such as Salsoul Records (Ken, Stanley, and Joseph Cayre), West End Records (Mel Cheren), Casablanca (Neil Bogart), and Prelude (Marvin Schlachter), to name a few. The genre was also shaped by Tom Moulton, who wanted to extend the enjoyment of dance songs — thus creating the extended mix or "remix", going from a three-minute 45 rpm single to the much longer 12" record. Other influential DJs and remixers who helped to establish what became known as the "disco sound" included David Mancuso, Nicky Siano, Shep Pettibone, Larry Levan, Walter Gibbons, and Chicago-based Frankie Knuckles. Frankie Knuckles was not only an important disco DJ; he also helped to develop house music in the 1980s. Disco hit the television airwaves as part of the music/dance variety show Soul Train in 1971 hosted by Don Cornelius, then Marty Angelo's Disco Step-by-Step Television Show in 1975, Steve Marcus' Disco Magic/Disco 77, Eddie Rivera's Soap Factory, and Merv Griffin's Dance Fever, hosted by Deney Terrio, who is credited with teaching actor John Travolta to dance for his role in the film Saturday Night Fever, as well as DANCE, based out of Columbia, South Carolina. In 1974, New York City's WPIX-FM premiered the first disco radio show. Early disco culture in the United States In the 1970s, the key counterculture of the 1960s, the hippie movement, was fading away. The economic prosperity of the previous decade had declined, and unemployment, inflation and crime rates had soared. Political issues like the backlash from the Civil Rights Movement culminating in the form of race riots, the Vietnam War, the assassinations of Dr. Martin Luther King Jr. and John F. Kennedy, and the Watergate scandal, left many feeling disillusioned and hopeless. The start of the '70s was marked by a shift in the consciousness of the American people: the rise of the feminist movement, identity politics, gangs, etc. very much shaped this era. Disco music and disco dancing provided an escape from negative social and economic issues. The non-partnered dance style of disco music allowed people of all races and sexual orientations to enjoy the dancefloor atmosphere. In Beautiful Things in Popular Culture, Simon Frith highlights the sociability of disco and its roots in 1960s counterculture. "The driving force of the New York underground dance scene in which disco was forged was not simply that city's complex ethnic and sexual culture but also a 1960s notion of community, pleasure and generosity that can only be described as hippie", he says. "The best disco music contained within it a remarkably powerful sense of collective euphoria." The birth of disco is often claimed to be found in the private dance parties held by New York City DJ David Mancuso's home that became known as The Loft, an invitation-only non-commercial underground club that inspired many others. He organized the first major party in his Manhattan home on Valentine's Day 1970 with the name "Love Saves The Day". After some months the parties became weekly events and Mancuso continued to give regular parties into the 1990s. Mancuso required that the music played had to be soulful, rhythmic, and impart words of hope, redemption, or pride. When Mancuso threw his first informal house parties, the gay community (which made up much of The Loft's attendee roster) was often harassed in the gay bars and dance clubs, with many gay men carrying bail money with them to gay bars. But at The Loft and many other early, private discotheques, they could dance together without fear of police action thanks to Mancuso's underground, yet legal, policies. Vince Aletti described it "like going to party, completely mixed, racially and sexually, where there wasn't any sense of someone being more important than anyone else," and Alex Rosner reiterated this saying "It was probably about sixty percent black and seventy percent gay...There was a mix of sexual orientation, there was a mix of races, mix of economic groups. A real mix, where the common denominator was music." Film critic Roger Ebert called the popular embrace of disco's exuberant dance moves an escape from "the general depression and drabness of the political and musical atmosphere of the late seventies." Pauline Kael, writing about the disco-themed film Saturday Night Fever, said the film and disco itself touched on "something deeply romantic, the need to move, to dance, and the need to be who you'd like to be. Nirvana is the dance; when the music stops, you return to being ordinary." Early disco culture in the United Kingdom In the late 1960s, uptempo soul with heavy beats and some associated dance styles and fashion were picked up in the British mod scene and formed the northern soul movement. Originating at venues such as the Twisted Wheel in Manchester, it quickly spread to other UK dancehalls and nightclubs like the Chateau Impney (Droitwich Spa|Droitwich]]), Catacombs (Wolverhampton), the Highland Rooms at Blackpool Mecca, Golden Torch (Stoke-on-Trent) and Wigan Casino. As the favoured beat became more uptempo and frantic in the early 1970s, northern soul dancing became more athletic, somewhat resembling the later dance styles of disco and break dancing. Featuring spins, flips, karate kicks and backdrops, club dancing styles were often inspired by the stage performances of touring American soul acts such as Little Anthony & the Imperials and Jackie Wilson. In 1974, there were an estimated 25,000 mobile discos and 40,000 professional disc jockeys in the United Kingdom. Mobile discos were hired deejays that brought their own equipment to provide music for special events. Glam rock tracks were popular, with, for example, Gary Glitter's 1972 single "Rock and Roll Part 2" becoming popular on UK dance floors while it did not get much radio airplay. 1974–1977: Rise to mainstream From 1974 to 1977, disco music increased in popularity as many disco songs topped the charts. The Hues Corporation's "Rock the Boat" (1974), a US number-one single and million-seller, was one of the early disco songs to reach number one. The same year saw the release of "Kung Fu Fighting", performed by Carl Douglas and produced by Biddu, which reached number one in both the UK and US, and became the best-selling single of the year and one of the best-selling singles of all time with 11 million records sold worldwide, helping to popularize disco to a great extent. Another notable disco success that year was George McCrae's "Rock Your Baby": it became the United Kingdom's first number one chart disco single. In the northwestern sections of the United Kingdom, the northern soul explosion, which started in the late 1960s and peaked in 1974, made the region receptive to disco, which the region's disc jockeys were bringing back from New York City. The shift by some DJs to the newer sounds coming from the U.S.A. resulted in a split in the scene, whereby some abandoned the 1960s soul and pushed a modern soul sound which tended to be more closely aligned with disco than soul. In 1975, Gloria Gaynor released her first side-long vinyl album, which included a remake of the Jackson 5's "Never Can Say Goodbye" (which, in fact, is also the album title) and two other songs, "Honey Bee" and her disco version of "Reach Out (I'll Be There)", first topped the Billboard disco/dance charts in November 1974. Later in 1978, Gaynor's number-one disco song was "I Will Survive", which was seen as a symbol of female strength and a gay anthem, like her further disco hit, a 1983 remake of "I Am What I Am"; in 1979 she released "Let Me Know (I Have a Right)", a single which gained popularity in the civil rights movements. Also in 1975, Vincent Montana Jr.'s Salsoul Orchestra contributed with their Latin-flavored orchestral dance song "Salsoul Hustle", reaching number four on the Billboard Dance Chart and their 1976 hits "Tangerine" and "Nice 'n' Naasty", the first being a cover of a 1941 song. Songs such as Van McCoy's 1975 "The Hustle" and the humorous Joe Tex 1977 "Ain't Gonna Bump No More (With No Big Fat Woman)" gave names to the popular disco dances "the Bump" and "the Hustle". Other notable early successful disco songs include Barry White's "You're the First, the Last, My Everything" (1974), Labelle's "Lady Marmalade" (1974), Disco-Tex and the Sex-O-Lettes' "Get Dancin'" (1974), Silver Convention's "Fly, Robin, Fly" (1975) and "Get Up and Boogie" (1976) and Johnny Taylor's "Disco Lady" (1976). Formed by Harry Wayne Casey (a.k.a. "KC") and Richard Finch, Miami's KC and the Sunshine Band had a string of disco-definitive top-five singles between 1975 and 1977, including "Get Down Tonight", "That's the Way (I Like It)", "(Shake, Shake, Shake) Shake Your Booty", "I'm Your Boogie Man" and "Keep It Comin' Love". In this period, rock bands like the English Electric Light Orchestra featured in their songs a violin sound that became a staple of disco music, as in the 1975 hit "Evil Woman", although the genre was correctly described as orchestral rock. Other disco producers such as Tom Moulton took ideas and techniques from dub music (which came with the increased Jamaican migration to New York City in the 1970s) to provide alternatives to the "four on the floor" style that dominated. DJ Larry Levan utilized styles from dub and jazz and remixing techniques to create early versions of house music that sparked the genre. Motown turning disco Norman Whitfield was an influential producer and songwriter at Motown records, renowned for creating innovative "psychedelic soul" songs with many hits for Marvin Gaye, the Velvelettes, the Temptations and Gladys Knight & The Pips. From around the production of the Temptations' album Cloud Nine in 1968, he incorporated some psychedelic influences and started to produce longer, dance-friendly tracks, with more room for elaborate rhythmic instrumental parts. An example of such a long psychedelic soul track is "Papa Was a Rollin' Stone", which appeared as a single edit of almost seven minutes and an approximately 12-minute-long 12" version in 1972. By the early 70s, many of Whitfield's productions evolved more and more towards funk and disco, as heard on albums by the Undisputed Truth and the 1973 album G.I.T.: Get It Together by The Jackson 5. The Undisputed Truth, a Motown recording act assembled by Whitfield to experiment with his psychedelic soul production techniques, found success with their 1971 song "Smiling Faces Sometimes". Their disco single "You + Me = Love" (number 43) was produced by Whitfield and made number 2 on the US Dance Charts in 1976. In 1975, Whitfield left Motown and founded his own label Whitfield records, on which also "You + Me = Love" was released. Whitfield produced some more disco hits, including "Car Wash" (1976) by Rose Royce from the album soundtrack to the 1976 film Car Wash. In 1977, singer, songwriter and producer Willie Hutch, who had been signed to Motown since 1970, now signed with Whitfield's new label, and scored a successful disco single with his song "In and Out" in 1982. Other Motown artists turned to disco as well. Diana Ross embraced the disco sound with her successful 1976 outing "Love Hangover" from her self-titled album. Her 1980 dance classics "Upside Down" and "I'm Coming Out" were written and produced by Nile Rodgers and Bernard Edwards of the group Chic. The Supremes, the group that made Ross famous, scored a handful of hits in the disco clubs without her, most notably 1976's "I'm Gonna Let My Heart Do the Walking" and, their last charted single before disbanding, 1977's "You're My Driving Wheel". At the request of Motown that he produce songs in the disco genre, Marvin Gaye released "Got to Give It Up" in 1978, despite his dislike of disco. He vowed not to record any songs in the genre, and actually wrote the song as a parody. However, several of Gaye's songs have disco elements, including "I Want You" (1975). Stevie Wonder released the disco single "Sir Duke" in 1977 as a tribute to Duke Ellington, the influential jazz legend who had died in 1974. Smokey Robinson left the Motown group the Miracles for a solo career in 1972 and released his third solo album A Quiet Storm in 1975, which spawned and lent its name to the "Quiet Storm" musical programming format and subgenre of R&B. It contained the disco single "Baby That's Backatcha". Other Motown artists who scored disco hits include: Robinson's former group, the Miracles, with "Love Machine" (1975), Eddie Kendricks with "Keep On Truckin'" (1973), the Originals with "Down to Love Town" (1976) and Thelma Houston with her cover of the Harold Melvin and the Blue Notes song "Don't Leave Me This Way" (1976). The label continued to release successful songs into the 1980s with Rick James' "Super Freak" (1981), and the Commodores' "Lady (You Bring Me Up)" (1981). Several of Motown's solo artists who left the label went on to have successful disco songs. Mary Wells, Motown's first female superstar with her signature song "My Guy" (written by Smokey Robinson), abruptly left the label in 1964. She briefly reappeared on the charts with the disco song "Gigolo" in 1980. Jimmy Ruffin, the elder brother of the Temptations lead singer David Ruffin, was also signed to Motown, and released his most successful and well-known song "What Becomes of the Brokenhearted" as a single in 1966. Ruffin eventually left the record label in the mid-1970s, but saw success with the 1980 disco song "Hold On (To My Love)", which was written and produced by Robin Gibb of the Bee Gees, for his album Sunrise. Edwin Starr, known for his Motown protest song "War" (1970), reentered the charts in 1979 with a pair of disco songs, "Contact" and "H.A.P.P.Y. Radio". Kiki Dee became the first white British singer to sign with Motown in the US, and released one album, Great Expectations (1970), and two singles "The Day Will Come Between Sunday and Monday" (1970) and "Love Makes the World Go Round" (1971), the latter giving her first-ever chart entry (number 87 on the US Chart). She soon left the company and signed with Elton John's The Rocket Record Company, and in 1976 had her biggest and best-known single, "Don't Go Breaking My Heart", a disco duet with John. The song was intended as an affectionate disco-style pastiche of the Motown sound, in particular the various duets recorded by Marvin Gaye with Tammi Terrell and Kim Weston. Many Motown groups who had left the record label charted with disco songs. The Jackson 5, one of Motown's premier acts in the early 1970s, left the record company in 1975 (Jermaine Jackson, however, remained with the label) after successful songs like "I Want You Back" (1969) and "ABC" (1970), and even the disco song "Dancing Machine" (1974). Renamed as 'the Jacksons' (as Motown owned the name 'the Jackson 5'), they went on to find success with disco songs like "Blame It on the Boogie" (1978), "Shake Your Body (Down to the Ground)" (1979) and "Can You Feel It?" (1981) on the Epic label. The Isley Brothers, whose short tenure at the company had produced the song "This Old Heart of Mine (Is Weak for You)" in 1966, went on release successful disco songs like "That Lady" (1973) and "It's a Disco Night (Rock Don't Stop)" (1979). Gladys Knight and the Pips, who recorded the most successful version of "I Heard It Through the Grapevine" (1967) before Marvin Gaye, scored commercially successful singles such as "Baby, Don't Change Your Mind" (1977) and "Bourgie, Bourgie" (1980) in the disco era. The Detroit Spinners were also signed to the Motown label and saw success with the Stevie Wonder-produced song "It's a Shame" in 1970. They left soon after, on the advice of fellow Detroit native Aretha Franklin, to Atlantic Records, and there had disco songs like "The Rubberband Man" (1976). In 1979, they released a successful cover of Elton John's "Are You Ready for Love", as well as a medley of the Four Seasons' song "Working My Way Back to You" and Michael Zager's "Forgive Me, Girl". The Four Seasons themselves were briefly signed to Motown's MoWest label, a short-lived subsidiary for R&B and soul artists based on the West Coast, and there the group produced one album, Chameleon (1972) – to little commercial success in the US. However, one single, "The Night", was released in Britain in 1975, and thanks to popularity from the Northern Soul circuit, reached number seven on the UK Singles Chart. The Four Seasons left Motown in 1974 and went on to have a disco hit with their song "December, 1963 (Oh, What a Night)" (1975) for Warner Curb Records. Eurodisco By far the most successful Euro disco act was ABBA (1972–1982). This Swedish quartet, which sang primarily in English, found success with singles such as "Waterloo" (1974), "Fernando" (1976), "Take a Chance on Me" (1978), "Gimme! Gimme! Gimme! (A Man After Midnight)" (1979), and their signature smash hit "Dancing Queen" (1976)—ranks as the Fourth best-selling act of all time. In 1970s Munich, West Germany, music producers Giorgio Moroder and Pete Bellotte made a decisive contribution to disco music with a string of hits for Donna Summer, which became known as the "Munich Sound". In 1975, Summer suggested the lyric "Love to Love You Baby" to Moroder and Bellotte, who turned the lyric into a full disco song. The final product, which contained the vocalizations of a series of simulated orgasms, initially was not intended for release, but when Moroder played it in the clubs it caused a sensation and he released it. The song became an international hit, reaching the charts in many European countries and the US (No. 2). It has been described as the arrival of the expression of raw female sexual desire in pop music. A 17-minute 12-inch single was released. The 12" single became and remains a standard in discos today. In 1976 Donna Summer's version of "Could It Be Magic" brought disco further into the mainstream. In 1977 Summer, Moroder and Bellotte further released "I Feel Love", as the B-side of "Can't We Just Sit Down (And Talk It Over)", which revolutionized dance music with its mostly electronic production and was a massive worldwide success, spawning the Hi-NRG subgenre. Giorgio Moroder was described by AllMusic as "one of the principal architects of the disco sound". Another successful disco music project by Moroder at that time was Munich Machine (1976–1980). Boney M. (1974–1986) was a West German disco group of four West Indian singers and dancers masterminded by record producer Frank Farian. Boney M. charted worldwide with such songs as "Daddy Cool" (1976) "Ma Baker" (1977) and "Rivers Of Babylon" (1978). Another successful West German disco recording act was Silver Convention (1974–1979). The German group Kraftwerk also had an influence on Euro disco. In France, Dalida released "J'attendrai" ("I Will Wait") in 1975, which also became successful in Canada, Europe and Japan. Dalida successfully adjusted herself to disco era and released at least a dozen of songs that charted among top number 10 in whole Europe and wider. Claude François, who re-invented himself as the king of French disco, released "La plus belle chose du monde", a French version of the Bee Gees song "Massachusetts", which became successful in Canada and Europe and "Alexandrie Alexandra" was posthumously released on the day of his burial and became a worldwide success. Cerrone's early songs, "Love in C Minor" (1976), "Supernature" (1977) and "Give Me Love" (1978) were successful in the US and Europe. Another Euro disco act was the French diva Amanda Lear, where Euro disco sound is most heard in "Enigma (Give a Bit of Mmh to Me)" (1978). French producer Alec Costandinos assembled the disco group Love and Kisses (1977–1982). In Italy Raffaella Carrà is the most successful disco act, alongside La Bionda, Hermanas Goggi and Oliver Onions. Her greatest international single was "Tanti Auguri" ("Best Wishes"), which has become a popular song with gay audiences. The song is also known under its Spanish title "Para hacer bien el amor hay que venir al sur" (which refers to Southern Europe, since the song was recorded and taped in Spain). The Estonian version of the song "Jätke võtmed väljapoole" was performed by Anne Veski. "A far l'amore comincia tu" ("To make love, your move first") was another success for her internationally, known in Spanish as "En el amor todo es empezar", in German as "Liebelei", in French as "Puisque tu l'aimes dis le lui", and in English as "Do It, Do It Again". It was her only entry to the UK Singles Chart, reaching number 9, where she remains a one-hit wonder. In 1977, she recorded another successful single, "Fiesta" ("The Party" in English) originally in Spanish, but then recorded it in French and Italian after the song hit the charts. "A far l'amore comincia tu" has also been covered in Turkish by a Turkish popstar Ajda Pekkan as "Sakın Ha" in 1977.

Scottish origin. The Donegal fiddlers may well have been the route by which Scottish tunes such as Lucy Campbell, Tarbolton Lodge (Tarbolton) and The Flagon (The Flogging Reel), that entered the Irish repertoire. These players prided themselves on their technical abilities, which included playing in higher positions (fairly uncommon among traditional Irish fiddlers), and sought out material which would demonstrate their skills. As Irish music was consolidated and organised under the Comhaltas Ceoltóirí Éireann movement in the 1960s, both strengthened the interest in traditional music but sometimes conflicted with the Donegal tradition and its social conventions. The rigidly organised sessions of the Comhaltas reflected the traditions of Southern Ireland and Donegal fiddlers like John Doherty considered the National repertoire with its strong focus on reels to be less diverse than that of Donegal with its varied rhythms. Other old fiddlers dislike the ways comhaltas sessions were organised with a committee player, often not himself a musician, in charge. Sometimes Comhaltas representatives would even disparage the Donegal tradition, with its Scottish flavour, as being un-Irish, and prohibit them from playing local tunes with Scottish genealogies such as the "Highlands" at Comhaltas sessions. This sometimes cause antagonism between Donegal players and the main organisation of traditional music in Ireland. Outside of the Comhaltas movement however, Donegal fiddling stood strong with Paddy Glackin of Ceoltorí Laighean and the Bothy Band and later Tommy Peoples also with the Bothy Band and Mairead Ni Mhaonaigh with Altan, who all drew attention and prestige to the Donegal tradition within folk music circles throughout Ireland. Description of style The Donegal style of fiddling is a label often applied to music from this area, though one also might plausibly identify several different, but related, styles within the county. To the extent to which there is one common style in the county, it is characterised by a rapid pace; a tendency to be more un-swung in the playing of the fast dance tune types (reel and jigs); short (non-slurred), aggressive bowing, sparse ornamentation, the use of bowed triplets more often than trills as ornaments, the use of double stops and droning; and the occurrence of "playing the octave", with one player playing the melody and the other playing the melody an octave lower. None of these characteristics are universal, and there is some disagreement as to the extent to which there is a common style at all. In general, however, the style is rather aggressive. Another feature of Donegal fiddling that makes it distinctive among Irish musical traditions is the variety of rare tune types that are played. Highlands, a type of tune in time with some similarities to Scottish strathspeys, which are also played in Donegal, are one of the most commonly played types of tune in the county. Other tune types common solely in the county include barndances, also called "Germans," and mazurkas. Fiddlers of the Donegal tradition Historical There are a number of different strands to the history of fiddle playing in County Donegal. Perhaps the best-known and, in the last half of the twentieth century, the most influential has been that of the Doherty family. Hugh Doherty is the first known musician of this family. Born in 1790, he headed an unbroken tradition of fiddlers and pipers in the Doherty family until the death, in 1980, of perhaps the best-known Donegal fiddler, John Doherty. John, a travelling tinsmith, was known for his extremely precise and fast finger- and bow-work and vast repertoire, and is considered to be one of the greatest Irish fiddlers ever recorded. John's older brother, Mickey, was also recorded and, though Mickey was another of the great Irish fiddlers, his reputation has been overshadowed by John's. There is no single Donegal style but several distinctive styles. These styles traditionally come from the geographical isolated regions of Donegal including Inishowen, eastern Donegal, The Rosses and Gweedore, Croaghs, Teelin, Kilcar, Glencolmcille, Ballyshannon and Bundoran. Even with improved communications and transport, these regions still have recognisably different ways of fiddle playing. Notable deceased players of the older Donegal styles include Neillidh ("Neilly") Boyle, Francie Byrne, Con Cassidy, Frank Cassidy, James Byrne (1946–2008), P.V. O'Donnell (2011), and Tommy Peoples (1948–2018). Currently living Donegal fiddlers, include, Vincent Campbell, John Gallagher, Paddy Glackin, and Danny O'Donnell. Modern Fiddle playing continues to be popular in Donegal. The three fiddlers of the Donegal "supergroup" Altan, Mairéad Ní Mhaonaigh, Paul O'Shaughnessy, and Ciarán Tourish, are generally admired within Donegal. An example of another fiddler-player from Donegal is Liz Doherty. Another well regarded fiddle player hailing from Donegal is Aidan O'Donnell. TG4 Young Musician of the Year 2010 Aidan O'Donnell has been described as one of the finest young Irish musicians at present. He began his music making at the age of 12, and since then has performed with some of traditional music's | unaccompanied listening pieces in addition to the more common dance music. The influences between Scotland and Donegal went both ways and were furthered by a wave of immigration from Donegal to Scotland in the 19th century (the regions share common names of dances), as can be heard in the volume of strathspeys, schottisches, marches, and Donegal's own strong piping tradition, has influenced and been influenced by music, and by the sounds, ornaments, and repertoire of the Píob Mhór, the traditional bagpipes of Ireland and Scotland. There are other differences between the Donegal style and the rest of Ireland. Instruments such as the tin whistle, flute, concertina and accordion were very rare in Donegal until modern times. Traditionally the píob mór and the fiddle were the only instruments used and the use of pipe or fiddle music was common in old wedding customs. Migrant workers carried their music to Scotland and also brought back a number of tunes of Scottish origin. The Donegal fiddlers may well have been the route by which Scottish tunes such as Lucy Campbell, Tarbolton Lodge (Tarbolton) and The Flagon (The Flogging Reel), that entered the Irish repertoire. These players prided themselves on their technical abilities, which included playing in higher positions (fairly uncommon among traditional Irish fiddlers), and sought out material which would demonstrate their skills.

repeating shotguns is the ability to have more than one choke at a time. Some shotgun shooting sports, such as skeet shooting, use crossing targets presented in a narrow range of distance, and only require one level of choke. Other sports, like sporting clays, give the shooter targets at differing ranges, and targets that might approach or recede from the shooter, and so must be engaged at differing ranges. Having two barrels lets the shooter use a more open choke for near targets, and a tighter choke for distant targets, providing the optimal shot pattern for each distance. The disadvantage lies in the fact that the barrels of a double-barreled shotgun, whether O/U or S×S, are not parallel, but slightly angled, so that shots from the barrels converge, usually at "40 yards out". For the S×S configuration, the shotstring continues on its path to the opposite side of the rib after the converging point; for example, the left barrel's discharge travels on the left of the rib till it hits dead center at 40 yards out, after that, the discharge continues on to the right. In the O/U configuration with a parallel rib, both barrels' discharges will keep to the dead center, but the discharge from the "under" barrel will shoot higher than the discharge from the "over" barrel after 40 yards. Thus, double-barreled shotguns are accurate only at practical shotgun ranges, though the range of their ammunition easily exceeds four to six times that distance. S×S shotguns are often more expensive, and may take more practice to aim effectively than a O/U. The off-center nature of the recoil in a S×S gun may make shooting the body-side barrel slightly more painful by comparison to an O/U, single-shot, or pump/lever action shotgun. Gas-operated, and to a lesser extent recoil-operated, designs will recoil less than either. More S×S than O/U guns have traditional "cast-off" stocks, where the end of the buttstock veers slightly to the right, allowing a right-handed user to point the gun more easily. Double-barreled shotguns are also inherently more safe, as whether the shotgun is loaded or can be fired can be ascertained by anyone present if the action is broken open, for instance on a skeet, trap or hunting clays course when another shooter is firing; if the action is open, the gun cannot fire. Similarly, doubles are more easily examined to see if loaded than pump or semi-automatic shotguns, whose bolt must be opened and chamber closely examined or felt to make sure it is unloaded; with a double gun (or a break-action single gun), whether the gun is loaded, i.e., has cartridges in any chamber, is easily and immediately seen with a glance (and just as easily unloaded). Trigger mechanism The early doubles used two triggers, one for each barrel, located front to back inside the trigger guard. The index finger was used to pull either trigger, as having two fingers inside the trigger guard can cause a very undesirable recoil-induced double-discharge. Double-trigger designs are typically set up for right-handed users. In double-trigger designs, it is often possible to pull both triggers at once, firing both barrels simultaneously, though this is generally not recommended as it doubles the recoil, battering both shotgun and shooter, particularly if it was unanticipated or unintended.

Discharging both barrels at the same time has long been a hunting trick employed by hunters using 8 gauge "elephant" shotguns, firing the two two-ounce slugs for sheer stopping power at close range. Later models use a single trigger that alternately fires both barrels, called a single selective trigger or SST. The SST does not allow firing both barrels at once, since the single trigger must be pulled twice in order to fire both barrels. The change from one barrel to the other may be done by a clockwork type system, where a cam alternates between barrels, or by an inertial system where the recoil of firing the first barrel toggles the trigger to the next barrel. A double-barreled shotgun with an inertial trigger works best with full power shotshells; shooting low recoil shotshells often will not reliably toggle the inertial trigger, causing an apparent failure to fire occasionally when attempting to depress the trigger a second time to fire the second barrel (this also can happen if the first shell fails to fire). Generally there is a method of selecting the order in which the barrels of an SST shotgun fire; commonly this is done through manipulation of the safety, pushing to one side to select top barrel first and the other side to select bottom barrel first. In the event that an inertial trigger does not toggle to the second barrel when firing low recoil shotshells, manually selecting the order to the second barrel will enable the second barrel to fire when the trigger is depressed again. One of the advantages of double-barreled shotgun with double triggers or SST, is that the second shot can be taken almost immediately after the first with merely a second trigger pull, without needing to manually operate the action (which will |
desserts moist. Many desserts also contain eggs, in order to form custard or to aid in the rising and thickening of a cake-like substance. Egg yolks specifically contribute to the richness of desserts. Egg whites can act as a leavening agent or provide structure. Further innovation in the healthy eating movement has led to more information being available about vegan and gluten-free substitutes for the standard ingredients, as well as replacements for refined sugar. Desserts can contain many spices and extracts to add a variety of flavors. Salt and acids are added to desserts to balance sweet flavors and create a contrast in flavors. Some desserts are coffee-flavored, for example an iced coffee soufflé or coffee biscuits. Alcohol can also be used as an ingredient, to make alcoholic desserts. Varieties and elements Dessert consist of variations of tasted, textures, and appearances. Desserts can be defined as a usually sweeter course that concludes a meal. This definition includes a range of courses ranging from fruits or dried nuts to multi-ingredient cakes and pies. Many cultures have different variations of dessert. In modern times the variations of desserts have usually been passed down or come from geographical regions. This is one cause for the variation of desserts. These are some major categories in which desserts can be placed. Cakes Cakes are sweet tender breads made with sugar and delicate flour. Cakes can vary from light, airy sponge cakes to dense cakes with less flour. Common flavorings include dried, candied or fresh fruit, nuts, cocoa or extracts. They may be filled with fruit preserves or dessert sauces (like pastry cream), iced with buttercream or other icings, and decorated with marzipan, piped borders, or candied fruit. Cake is often served as a celebratory dish on ceremonial occasions, for example weddings, anniversaries, and birthdays. Small-sized cakes have become popular, in the form of cupcakes and petits fours. Puddings Puddings are similar to custards in that their base is creme or milk. However their primary difference is that puddings are thickened with starches such as corn starch or tapioca. On the other hand, custards are thickened using only eggs and are usually more firm. Small cakes and pastries A batched dough between a cake and pastry by the mix of ingredients. An Old French bescuit, commonly spelt in English as biscuit, is a derivation of Latin for twice-baked. A Dutch koekje, commonly spelt in English as cookie, is a derivation of cake-ie , meaning little cake. This form of dough can have a texture that is crisp, hard, chewy, or soft – in the UK a biscuit is the former two and a cookie is typically the latter. Examples include a ginger nut, shortbread biscuit and chocolate chip cookie. Other small cakes and pastries can also be counted as under these terms, due to their size and relative similarity to cookies and biscuits, such as jaffa cakes and Eccles cakes. Confection Confection, also called candy, sweets or lollies, features sugar or honey as a principal ingredient. Many involve sugar heated into crystals with subtle differences. Dairy and sugar based include caramel, fudge and toffee or taffy. They are multiple forms of egg and sugar meringues. and similar confections. Unheated sugar co-adulate into icings, preservatives and sauces with other ingredients. Chocolate Theobroma cacao beans can be a substitute or more commonly mixed with sugar to form chocolate. Pure, unsweetened dark chocolate contains primarily cocoa solids. Cocoa butter is also added in varying proportions. Much of the chocolate currently consumed is in the form of sweet chocolate, combining chocolate with sugar. Milk chocolate is sweet chocolate that additionally contains milk powder or condensed milk. White chocolate contains cocoa butter, sugar, and milk, but no cocoa solids. Dark chocolate is produced by adding fat and sugar to the cacao mixture, with no milk or much less than milk chocolate. Custards These kinds of desserts usually include a thickened dairy base. Custards are cooked and thickened with eggs. Baked custards include crème brûlée and flan. They are often used as ingredients in other desserts, for instance as a filling for pastries or pies. Deep-fried Many cuisines include a dessert made of deep-fried starch-based batter or dough. In many countries, a doughnut is a flour-based batter that has been deep-fried. It is sometimes filled with custard or jelly. Fritters are fruit pieces in a thick batter that have been deep fried. Gulab jamun is an Indian dessert made of milk solids kneaded into a dough, deep-fried, and soaked in honey. Churros are a deep-fried and sugared dough that is eaten as dessert or a snack in many countries. Frozen Ice cream, gelato, sorbet and shaved-ice desserts fit into this category. Ice cream is a cream base that is churned as it is frozen to create a creamy consistency. Gelato uses a milk base and has less air whipped in than ice cream, making it denser. Sorbet is made from churned fruit and is not dairy based. Shaved-ice desserts are made by shaving a block of ice and adding flavored syrup or juice | made by shaving a block of ice and adding flavored syrup or juice to the ice shavings. Gelatin Jellied desserts are made with a sweetened liquid thickened with gelatin or another thickening agent. They are traditional in many cultures. Grass jelly and annin tofu are Chinese jellied desserts. Yōkan is a Japanese jellied dessert. In English-speaking countries, many dessert recipes are based on gelatin with fruit or whipped cream added. The vegetarian substitute for Gelatin is Agar. Marshmallow is also most commonly made with gelatin. Pastries Pastries are sweet baked pastry products. Pastries can either take the form of light and flaky bread with an airy texture, such as a croissant or unleavened dough with a high fat content and crispy texture, such as shortbread. Pastries are often flavored or filled with fruits, chocolate, nuts, and spices. Pastries are sometimes eaten with tea or coffee as a breakfast food. Pies, cobblers, and clafoutis Pies and cobblers are a crust with a filling. The crust can be either made from either a pastry or crumbs. Pie fillings range from fruits to puddings; cobbler fillings are generally fruit-based. Clafoutis are made of batter poured over a fruit-based filling before baking. Sweet soups Tong sui, literally translated as "sugar water" and also known as tim tong, is a collective term for any sweet, warm soup or custard served as a dessert at the end of a meal in Cantonese cuisine. Tong sui are a Cantonese specialty and are rarely found in other regional cuisines of China. Outside of Cantonese-speaking communities, soupy desserts generally are not recognized as a distinct category, and the term tong sui is not used. Wines Dessert wines are sweet wines typically served with dessert. There is no simple definition of a dessert wine. In the UK, a dessert wine is considered to be any sweet wine drunk with a meal, as opposed to the white fortified wines (fino and amontillado sherry) drunk before the meal, and the red fortified wines (port and madeira) drunk after it. Thus, most fortified wines are regarded as distinct from dessert wines, but some of the less strong fortified white wines, such as Pedro Ximénez sherry and Muscat de Beaumes-de-Venise, are regarded as honorary dessert wines. In the United States, by contrast, a dessert wine is legally defined as any wine over 14% alcohol by volume, which includes all fortified wines - and is taxed at higher rates as a result. Examples include Sauternes and Tokaji Aszú. Gallery By continent Africa Throughout much of central and western Africa, there is no tradition of a dessert course following a meal. Fruit or fruit salad would be eaten instead, which may be spiced, or sweetened with a sauce. In some former colonies in the region, the colonial power has influenced desserts – for example, the Angolan cocada amarela (yellow coconut) resembles baked desserts in Portugal. Asia In Asia, desserts are often eaten between meals as snacks rather than as a concluding course. There is widespread use of rice flour in East Asian desserts, which often include local ingredients such as coconut milk, palm sugar, and tropical fruit. In India, where sugarcane has been grown and refined since before 500 BC, desserts have been an important part of the diet for thousands of years; types of desserts include burfis, halvahs, jalebis, and laddus. Dessert nowadays are made into drinks as well. Bubble tea, which originated in Taiwan, is a kind of dessert made with flavored tea or milk and tapioca. It is well known across the world. India Europe In Ukraine and Russia, breakfast foods such as nalysnyky or blintz or oladi (pancake), and syrniki are served with honey and jam as desserts. In the Netherlands vla is a popular dessert. It is a custard-like dessert that is served cold. Popular flavours are: vanilla, chocolate, caramel, and several fruit flavours. There is also hopjesvla which is flavoured like a Hopje, a Dutch coffee and caramel sweet. North America European colonization of the Americas yielded the introduction of a number of ingredients and cooking styles. The various styles continued expanding well into the 19th and 20th centuries, proportional to the influx of immigrants. South America Dulce de leche is a very common confection in Argentina. In Bolivia, sugarcane, honey and coconut are traditionally used in desserts. Tawa tawa is a Bolivian sweet fritter prepared using sugar cane, and helado de canela is a dessert that is similar to sherbet which is prepared with cane sugar and cinnamon. Coconut tarts, puddings cookies and candies are also consumed in Bolivia. Brazil has a variety of candies such as brigadeiros (chocolate fudge balls), cocada (a coconut sweet), beijinhos (coconut truffles and clove) and romeu e julieta (cheese with a guava jam known as goiabada). Peanuts are used to make paçoca, rapadura and pé-de-moleque. Local common fruits are turned in juices and used to make chocolates, ice pops and ice cream. In Chile, kuchen has been described as a "trademark dessert". Several desserts in Chile are prepared with manjar, (caramelized milk), including alfajor, flan, cuchufli and arroz con leche. Desserts consumed in Colombia include dulce de leche, waffle cookies, puddings, nougat, coconut with syrup and thickened milk with sugarcane syrup. Desserts in Ecuador tend to be simple, and desserts are a moderate part of the cuisine. Desserts consumed in Ecuador include tres leches cake, flan, candies and various sweets. Oceania Desserts are typically eaten in Australia, and most daily meals "end with simple desserts", which can include various fruits. More complex desserts include cakes, pies and cookies, which are sometimes served during special occasions. Market The market for desserts has grown over the last few decades, which was greatly increased by the |
symbol denotes the exclusive-OR (XOR) operation. The F-function scrambles half a block together with some of the key. The output from the F-function is then combined with the other half of the block, and the halves are swapped before the next round. After the final round, the halves are swapped; this is a feature of the Feistel structure which makes encryption and decryption similar processes. The Feistel (F) function The F-function, depicted in Figure 2, operates on half a block (32 bits) at a time and consists of four stages: Expansion: the 32-bit half-block is expanded to 48 bits using the expansion permutation, denoted E in the diagram, by duplicating half of the bits. The output consists of eight 6-bit (8 × 6 = 48 bits) pieces, each containing a copy of 4 corresponding input bits, plus a copy of the immediately adjacent bit from each of the input pieces to either side. Key mixing: the result is combined with a subkey using an XOR operation. Sixteen 48-bit subkeys—one for each round—are derived from the main key using the key schedule (described below). Substitution: after mixing in the subkey, the block is divided into eight 6-bit pieces before processing by the S-boxes, or substitution boxes. Each of the eight S-boxes replaces its six input bits with four output bits according to a non-linear transformation, provided in the form of a lookup table. The S-boxes provide the core of the security of DES—without them, the cipher would be linear, and trivially breakable. Permutation: finally, the 32 outputs from the S-boxes are rearranged according to a fixed permutation, the P-box. This is designed so that, after permutation, the bits from the output of each S-box in this round are spread across four different S-boxes in the next round. The alternation of substitution from the S-boxes, and permutation of bits from the P-box and E-expansion provides so-called "confusion and diffusion" respectively, a concept identified by Claude Shannon in the 1940s as a necessary condition for a secure yet practical cipher. Key schedule Figure 3 illustrates the key schedule for encryption—the algorithm which generates the subkeys. Initially, 56 bits of the key are selected from the initial 64 by Permuted Choice 1 (PC-1)—the remaining eight bits are either discarded or used as parity check bits. The 56 bits are then divided into two 28-bit halves; each half is thereafter treated separately. In successive rounds, both halves are rotated left by one or two bits (specified for each round), and then 48 subkey bits are selected by Permuted Choice 2 (PC-2)—24 bits from the left half, and 24 from the right. The rotations (denoted by "<<<" in the diagram) mean that a different set of bits is used in each subkey; each bit is used in approximately 14 out of the 16 subkeys. The key schedule for decryption is similar—the subkeys are in reverse order compared to encryption. Apart from that change, the process is the same as for encryption. The same 28 bits are passed to all rotation boxes. Security and cryptanalysis Although more information has been published on the cryptanalysis of DES than any other block cipher, the most practical attack to date is still a brute-force approach. Various minor cryptanalytic properties are known, and three theoretical attacks are possible which, while having a theoretical complexity less than a brute-force attack, require an unrealistic number of known or chosen plaintexts to carry out, and are not a concern in practice. Brute-force attack For any cipher, the most basic method of attack is brute force—trying every possible key in turn. The length of the key determines the number of possible keys, and hence the feasibility of this approach. For DES, questions were raised about the adequacy of its key size early on, even before it was adopted as a standard, and it was the small key size, rather than theoretical cryptanalysis, which dictated a need for a replacement algorithm. As a result of discussions involving external consultants including the NSA, the key size was reduced from 128 bits to 56 bits to fit on a single chip. In academia, various proposals for a DES-cracking machine were advanced. In 1977, Diffie and Hellman proposed a machine costing an estimated US$20 million which could find a DES key in a single day. By 1993, Wiener had proposed a key-search machine costing US$1 million which would find a key within 7 hours. However, none of these early proposals were ever implemented—or, at least, no implementations were publicly acknowledged. The vulnerability of DES was practically demonstrated in the late 1990s. In 1997, RSA Security sponsored a series of contests, offering a $10,000 prize to the first team that broke a message encrypted with DES for the contest. That contest was won by the DESCHALL Project, led by Rocke Verser, Matt Curtin, and Justin Dolske, using idle cycles of thousands of computers across the Internet. The feasibility of cracking DES quickly was demonstrated in 1998 when a custom DES-cracker was built by the Electronic Frontier Foundation (EFF), a cyberspace civil rights group, at the cost of approximately US$250,000 (see EFF DES cracker). Their motivation was to show that DES was breakable in practice as well as in theory: "There are many people who will not believe a truth until they can see it with their own eyes. Showing them a physical machine that can crack DES in a few days is the only way to convince some people that they really cannot trust their security to DES." The machine brute-forced a key in a little more than 2 days' worth of searching. The next confirmed DES cracker was the COPACOBANA machine built in 2006 by teams of the Universities of Bochum and Kiel, both in Germany. Unlike the EFF machine, COPACOBANA consists of commercially available, reconfigurable integrated circuits. 120 of these field-programmable gate arrays (FPGAs) of type XILINX Spartan-3 1000 run in parallel. They are grouped in 20 DIMM modules, each containing 6 FPGAs. The use of reconfigurable hardware makes the machine applicable to other code breaking tasks as well. One of the more interesting aspects of COPACOBANA is its cost factor. One machine can be built for approximately $10,000. The cost decrease by roughly a factor of 25 over the EFF machine is an example of the continuous improvement of digital hardware—see Moore's law. Adjusting for inflation over 8 years yields an even higher improvement of about 30x. Since 2007, SciEngines GmbH, a spin-off company of the two project partners of COPACOBANA has enhanced and developed successors of COPACOBANA. In 2008 their COPACOBANA RIVYERA reduced the time to break DES to less than one day, using 128 Spartan-3 5000's. SciEngines RIVYERA held the record in brute-force breaking DES, having utilized 128 Spartan-3 5000 FPGAs. Their 256 Spartan-6 LX150 model has further lowered this time. In 2012, David Hulton and Moxie Marlinspike announced a system with 48 Xilinx Virtex-6 LX240T FPGAs, each FPGA containing 40 fully pipelined DES cores running at 400 MHz, for a total capacity of 768 gigakeys/sec. The system can exhaustively search the entire 56-bit DES key space in about 26 hours and this service is offered for a fee online. Attacks faster than brute force There are three attacks known that can break the full 16 rounds of DES with less complexity than a brute-force search: differential cryptanalysis (DC), linear cryptanalysis (LC), and Davies' attack. However, the | them up in safes, because they were considered U.S. government classified. They said do it. So I did it". Bruce Schneier observed that "It took the academic community two decades to figure out that the NSA 'tweaks' actually improved the security of DES." The algorithm as a standard Despite the criticisms, DES was approved as a federal standard in November 1976, and published on 15 January 1977 as FIPS PUB 46, authorized for use on all unclassified data. It was subsequently reaffirmed as the standard in 1983, 1988 (revised as FIPS-46-1), 1993 (FIPS-46-2), and again in 1999 (FIPS-46-3), the latter prescribing "Triple DES" (see below). On 26 May 2002, DES was finally superseded by the Advanced Encryption Standard (AES), following a public competition. On 19 May 2005, FIPS 46-3 was officially withdrawn, but NIST has approved Triple DES through the year 2030 for sensitive government information. The algorithm is also specified in ANSI X3.92 (Today X3 is known as INCITS and ANSI X3.92 as ANSI INCITS 92), NIST SP 800-67 and ISO/IEC 18033-3 (as a component of TDEA). Another theoretical attack, linear cryptanalysis, was published in 1994, but it was the Electronic Frontier Foundation's DES cracker in 1998 that demonstrated that DES could be attacked very practically, and highlighted the need for a replacement algorithm. These and other methods of cryptanalysis are discussed in more detail later in this article. The introduction of DES is considered to have been a catalyst for the academic study of cryptography, particularly of methods to crack block ciphers. According to a NIST retrospective about DES, The DES can be said to have "jump-started" the nonmilitary study and development of encryption algorithms. In the 1970s there were very few cryptographers, except for those in military or intelligence organizations, and little academic study of cryptography. There are now many active academic cryptologists, mathematics departments with strong programs in cryptography, and commercial information security companies and consultants. A generation of cryptanalysts has cut its teeth analyzing (that is, trying to "crack") the DES algorithm. In the words of cryptographer Bruce Schneier, "DES did more to galvanize the field of cryptanalysis than anything else. Now there was an algorithm to study." An astonishing share of the open literature in cryptography in the 1970s and 1980s dealt with the DES, and the DES is the standard against which every symmetric key algorithm since has been compared. Chronology Description DES is the archetypal block cipher—an algorithm that takes a fixed-length string of plaintext bits and transforms it through a series of complicated operations into another ciphertext bitstring of the same length. In the case of DES, the block size is 64 bits. DES also uses a key to customize the transformation, so that decryption can supposedly only be performed by those who know the particular key used to encrypt. The key ostensibly consists of 64 bits; however, only 56 of these are actually used by the algorithm. Eight bits are used solely for checking parity, and are thereafter discarded. Hence the effective key length is 56 bits. The key is nominally stored or transmitted as 8 bytes, each with odd parity. According to ANSI X3.92-1981 (Now, known as ANSI INCITS 92-1981), section 3.5: Like other block ciphers, DES by itself is not a secure means of encryption, but must instead be used in a mode of operation. FIPS-81 specifies several modes for use with DES. Further comments on the usage of DES are contained in FIPS-74. Decryption uses the same structure as encryption, but with the keys used in reverse order. (This has the advantage that the same hardware or software can be used in both directions.) Overall structure The algorithm's overall structure is shown in Figure 1: there are 16 identical stages of processing, termed rounds. There is also an initial and final permutation, termed IP and FP, which are inverses (IP "undoes" the action of FP, and vice versa). IP and FP have no cryptographic significance, but were included in order to facilitate loading blocks in and out of mid-1970s 8-bit based hardware. Before the main rounds, the block is divided into two 32-bit halves and processed alternately; this criss-crossing is known as the Feistel scheme. The Feistel structure ensures that decryption and encryption are very similar processes—the only difference is that the subkeys are applied in the reverse order when decrypting. The rest of the algorithm is identical. This greatly simplifies implementation, particularly in hardware, as there is no need for separate encryption and decryption algorithms. The ⊕ symbol denotes the exclusive-OR (XOR) operation. The F-function scrambles half a block together with some of the key. The output from the F-function is then combined with the other half of the block, and the halves are swapped before the next round. After the final round, the halves are swapped; this is a feature of the Feistel structure which makes encryption and decryption similar processes. The Feistel (F) function The F-function, depicted in Figure 2, operates on half a block (32 bits) at a time and consists of four stages: Expansion: the 32-bit half-block is expanded to 48 bits using the expansion permutation, denoted E in the diagram, by duplicating half of the bits. The output consists of eight 6-bit (8 × 6 = 48 bits) pieces, each containing a copy of 4 corresponding input bits, plus a copy of the immediately adjacent bit from each of the input pieces to either side. Key mixing: the result is combined with a subkey using an XOR operation. Sixteen 48-bit subkeys—one for each round—are derived from the main key using the key schedule (described below). Substitution: after mixing in the subkey, the block is divided into eight 6-bit pieces before processing by the S-boxes, or substitution boxes. Each of the eight S-boxes replaces its six input bits with four output bits according to a non-linear transformation, provided in the form of a lookup table. The S-boxes provide the core of the security of DES—without them, the cipher would be linear, and trivially breakable. Permutation: finally, the 32 outputs from the S-boxes are rearranged according to a fixed permutation, the P-box. This is designed so that, after permutation, the bits from the output of each S-box in this round are spread across four different S-boxes in the next round. The alternation of substitution from the S-boxes, and permutation of bits from the P-box and E-expansion provides so-called "confusion and diffusion" respectively, a concept identified by Claude Shannon in the 1940s as a necessary condition for a secure yet practical cipher. Key schedule Figure 3 illustrates the key schedule for encryption—the algorithm which generates the subkeys. Initially, 56 bits of the key are selected from the initial 64 by Permuted Choice 1 (PC-1)—the remaining eight bits are either discarded or used as parity check bits. The 56 bits are then divided into two 28-bit halves; each half is thereafter treated separately. In successive rounds, both halves are rotated left by one or two bits (specified for each round), and then 48 subkey bits are selected by Permuted Choice 2 (PC-2)—24 bits from the left half, and 24 from the right. The rotations (denoted by "<<<" in the diagram) mean that a different set of bits is used in each subkey; each bit is used in approximately 14 out of the 16 subkeys. The key schedule for decryption is similar—the subkeys are in reverse order compared |
fitted with double hulls, or an alternative design approved by IMO". However, in the aftermath of the Erika incident of the coast off France in December 1999, members of IMO adopted a revised schedule for the phase-out of single-hull tankers, which came into effect on 1 September 2003, with further amendments validated on 5 April 2005. After the Exxon Valdez oil spill disaster, when that ship grounded on Bligh Reef outside the port of Valdez, Alaska in 1989, the US Government required all new oil tankers built for use between US ports to be equipped with a full double hull. However, the damage to the Exxon Valdez penetrated sections of the hull (the slops oil tanks, or slop tanks) that were protected by a double bottom, or partial double hull. Maintenance issues Although double-hulled tankers reduce the likelihood of ships grazing rocks and creating holes in the hull, a double hull does not protect against major, high-energy collisions or groundings which cause the majority of oil pollution, despite this being the reason that the double hull was mandated by United States legislation. Double-hulled tankers, if poorly designed, constructed, maintained and operated can be as problematic, if not more problematic than their single-hulled counterparts. Double-hulled tankers have a more complex design and structure than their single-hulled counterparts, which means that they require more maintenance and care in operating, which if not subject to responsible monitoring and policing, may cause problems. Double hulls often result in the weight of the hull increasing by at least 20%, and because the steel weight of doubled-hulled tanks should not be greater than that of single-hulled ships, the individual hull walls are typically thinner and theoretically less resistant to wear. Double hulls by no means eliminate the possibility of the hulls breaking apart. Due to the air space between the hulls, there is also a potential problem with volatile gases seeping out through worn areas of the internal hull, increasing the risk of an explosion. Although several international conventions against pollution are in place, as of 2003 there was still no formal body setting international mandatory standards, although the International Safety Guide for Oil Tankers and Terminals (ISGOTT) | spill disaster in Alaska in 1989, the US Government required all new oil tankers built for use between US ports to be equipped with a full double hull. Reasons for use A number of manufacturers have embraced oil tankers with a double hull because it strengthens the hull of ships, reducing the likelihood of oil disasters in low-impact collisions and groundings over single-hull ships. They reduce the likelihood of leaks occurring at low speed impacts in port areas when the ship is under pilotage. Research of impact damage of ships has revealed that double-hulled tankers are unlikely to perforate both hulls in a collision, preventing oil from seeping out. However, for smaller tankers, U shaped tanks might be susceptible to "free flooding" across the double bottom and up to the outside water level each side of the cargo tank. Salvors prefer to salvage doubled-hulled tankers because they permit the use of air pressure to vacuum out the flood water. In the 1960s, collision proof double hulls for nuclear ships were extensively investigated, due to escalating concerns over nuclear accidents. The ability of double-hulled tankers to prevent or reduce oil spills led to double hulls being standardized for other types of ships including oil tankers by the International Convention for the Prevention of Pollution from Ships or MARPOL Convention.

contains little or no alcohol. This category includes low-alcohol beer, non-alcoholic wine, and apple cider if they contain a sufficiently low concentration of alcohol by volume (ABV). The exact definition of what is "non-alcoholic" and what is not depends on local laws: in the United Kingdom, "alcohol-free beer" is under 0.05% ABV, "de-alcoholised beer" is under 0.5%, while "low-alcohol beer" can contain no more than 1.2% ABV. The term "soft drink" specifies the absence of alcohol in contrast to "hard drink" and "drink". The term "drink" is theoretically neutral, but often is used in a way that suggests alcoholic content. Drinks such as soda pop, sparkling water, iced tea, lemonade, root beer, fruit punch, milk, hot chocolate, tea, coffee, milkshakes, and tap water and energy drinks are all soft drinks. Water Water is the world's most consumed drink, however, 97% of water on Earth is non-drinkable salt water. Fresh water is found in rivers, lakes, wetlands, groundwater, and frozen glaciers. Less than 1% of the Earth's fresh water supplies are accessible through surface water and underground sources which are cost effective to retrieve. In western cultures, water is often drunk cold. In the Chinese culture, it is typically drunk hot. Milk Milk is regarded as one of the "original" drinks, milk is the primary source of nutrition for babies. In many cultures of the world, especially the Western world, humans continue to consume dairy milk beyond infancy, using the milk of other animals (especially cattle, goats and sheep) as a drink. Soft drinks Carbonated drinks refer to drinks which have carbon dioxide dissolved into them. This can happen naturally through fermenting and in natural water spas or artificially by the dissolution of carbon dioxide under pressure. The first commercially available artificially carbonated drink is believed to have been produced by Thomas Henry in the late 1770s. Cola, orange, various roots, ginger, and lemon/lime are commonly used to create non-alcoholic carbonated drinks; sugars and preservatives may be added later. The most consumed carbonated soft drinks are produced by three major global brands: Coca-Cola, PepsiCo and the Dr Pepper Snapple Group. Juice and plant drinks Fruit juice is a natural product that contains few or no additives. Citrus products such as orange juice and tangerine juice are familiar breakfast drinks, while grapefruit juice, pineapple, apple, grape, lime, and lemon juice are also common. Coconut water is a highly nutritious and refreshing juice. Many kinds of berries are crushed; their juices are mixed with water and sometimes sweetened. Raspberry, blackberry and currants are popular juices drinks but the percentage of water also determines their nutritive value. Grape juice allowed to ferment produces wine. Fruits are highly perishable so the ability to extract juices and store them was of significant value. Some fruits are highly acidic and mixing them with water and sugars or honey was often necessary to make them palatable. Fruits can also be blended with ice and other ingredients to make a smoothie. Early storage of fruit juices was labor-intensive, requiring the crushing of the fruits and the mixing of the resulting pure juices with sugars before bottling. Vegetable juices are usually served warm or cold. Different types of vegetables can be used to make vegetable juice such as carrots, tomatoes, cucumbers, celery and many more. Some vegetable juices are mixed with some fruit juice to make the vegetable juice taste better. Many popular vegetable juices, particularly ones with high tomato content, are high in sodium, and therefore consumption of them for health must be carefully considered. Some vegetable juices provide the same health benefits as whole vegetables in terms of reducing risks of cardiovascular disease and cancer. Plant milk is a general term for any milk-like product that is derived from a plant source. The most common varieties internationally are soy milk, almond milk, rice milk and coconut milk. Sleep drinks A nightcap is a drink taken shortly before bedtime to induce sleep. For example, a small alcoholic drink or a cup of warm milk can supposedly promote a good night's sleep. Today, most nightcaps and relaxation drinks are generally non-alcoholic beverages containing calming ingredients. They are considered beverages which serve to relax a person. Unlike other calming beverages, such as tea, warm milk or milk with honey; relaxation drinks almost universally contain more than one active ingredient. Relaxation drinks have been known to contain other natural ingredients and are usually free of caffeine and alcohol but some have claimed to contain marijuana. Alcoholic drinks A drink is considered "alcoholic" if it contains ethanol, commonly known as alcohol (although in chemistry the definition of "alcohol" includes many other compounds). Beer has been a part of human culture for 8,000 years. In many countries, imbibing alcoholic drinks in a local bar or pub is a cultural tradition. Beer Beer is an alcoholic drink produced by the saccharification of starch and fermentation of the resulting sugar. The starch and saccharification enzymes are often derived from malted cereal grains, most commonly malted barley and malted wheat. Most beer is also flavoured with hops, which add bitterness and act as a natural preservative, though other flavourings such as herbs or fruit may occasionally be included. The preparation of beer is called brewing. Beer is the world's most widely consumed alcoholic drink, and is the third-most popular drink overall, after water and tea. It is said to have been discovered by goddess Ninkasi around 5300 BCE, when she accidentally discovered yeast after leaving grain in jars that were later rained upon and left for several days. Women have been the chief creators of beer throughout history due to its association with domesticity and it, throughout much of history, being brewed in the home for family consumption. Only in recent history have men begun to dabble in the field. It is thought by some to be the oldest fermented drink. Some of humanity's earliest known writings refer to the production and distribution of beer: the Code of Hammurabi included laws regulating beer and beer parlours, and "The Hymn to Ninkasi", a prayer to the Mesopotamian goddess of beer, served as both a prayer and as a method of remembering the recipe for beer in a culture with few literate people. Today, the brewing industry is a global business, consisting of several dominant multinational companies and many thousands of smaller producers ranging from brewpubs to regional breweries. Cider Cider is a fermented alcoholic drink made from fruit juice, most commonly and traditionally apple juice, but also the juice of peaches, pears ("Perry" cider) or other fruit. Cider may be made from any variety of apple, but certain cultivars grown solely for use in cider are known as cider apples. The United Kingdom has the highest per capita consumption of cider, as well as the largest cider-producing companies in the world, , the U.K. produces 600 million litres of cider each year (130 million imperial gallons). Wine Wine is an alcoholic drink made from fermented grapes or other fruits. The natural chemical balance of grapes lets them ferment without the addition of sugars, acids, enzymes, water, or other nutrients. Yeast consumes the sugars in the grapes and converts them into alcohol and carbon dioxide. Different varieties of grapes and strains of yeasts produce different styles of wine. The well-known variations result from the very complex interactions between the biochemical development of the fruit, reactions involved in fermentation, terroir and subsequent appellation, along with human intervention in the overall process. The final product may contain tens of thousands of chemical compounds in amounts varying from a few percent to a few parts per billion. Wines made from produce besides grapes are usually named after the product from which they are produced (for example, rice wine, pomegranate wine, apple wine and elderberry wine) and are generically called fruit wine. The term "wine" can also refer to starch-fermented or fortified drinks having higher alcohol content, such as barley wine, huangjiu, or sake. Wine has a rich history dating back thousands of years, with the earliest production so far discovered having occurred BC in Georgia. It had reached the Balkans by BC and was consumed and celebrated in ancient Greece and Rome. From its earliest appearance in written records, wine has also played an important role in religion. Red wine was closely associated with blood by the ancient Egyptians, who, according to Plutarch, avoided its free consumption as late as the 7th-century BC Saite dynasty, "thinking it to be the blood of those who had once battled against the gods". The Greek cult and mysteries of Dionysus, carried on by the Romans in their Bacchanalia, were the origins of western theater. Judaism incorporates it in the Kiddush and Christianity in its Eucharist, while alcohol consumption was forbidden in Islam. Spirits Spirits are distilled beverages that contain no added sugar and have at least 20% alcohol by volume (ABV). Popular spirits include borovička, brandy, gin, rum, slivovitz, tequila, vodka, and whisky. Brandy is a spirit created by distilling wine, whilst vodka may be distilled from any starch- or sugar-rich plant matter; most vodka today is produced from grains such as sorghum, corn, rye or wheat. Hot drinks Coffee Coffee is a brewed drink prepared from the roasted seeds of several species of an evergreen shrub of the genus Coffea. The two most common sources of coffee beans are the highly regarded Coffea arabica, and the "robusta" form of the hardier Coffea canephora. Coffee plants are cultivated in more than 70 countries. Once ripe, coffee "berries" are picked, processed, and dried to yield the seeds inside. The seeds are then roasted to varying degrees, depending on the desired flavor, before being ground and brewed to create coffee. Coffee is slightly acidic (pH 5.0–5.1) and can have a stimulating effect on humans because of its caffeine content. It is one of the most popular drinks in the world. It can be prepared and presented in a variety of ways. The effect of coffee on human health has been a subject of many studies; however, results have varied in terms of coffee's relative benefit. Coffee cultivation first took place in southern Arabia; the earliest credible evidence of coffee-drinking appears in the middle of the 15th century in the Sufi shrines of Yemen. Coffee may have been used socially in the renaissance period of the 17th century. The increasing trades between Europe and North Africa regions made coffee more widely available to Europeans gathering at social locations that served coffee, possibly contributing to the growth of coffeehouses. Hot chocolate Hot chocolate, also known as drinking chocolate or cocoa, is a heated drink consisting of shaved chocolate, melted chocolate or cocoa powder, heated milk or water, and usually a sweetener. Hot chocolate may be topped with whipped cream. Hot chocolate made with melted chocolate is sometimes called drinking chocolate, characterized by less sweetness and a thicker consistency. The first chocolate drink is believed to have been created by the Mayans around 2,500-3,000 years ago, and a cocoa drink was an essential part of Aztec culture by 1400 AD, by which they referred to as xocōlātl. The drink became popular in Europe after being introduced from Mexico in the New World and has undergone multiple changes since then. Until the 19th century, hot chocolate was even used medicinally to treat ailments such as liver and stomach diseases.Hot chocolate is consumed throughout the world and comes in multiple variations, including the spiced chocolate para mesa of Latin America, the very thick cioccolata calda served in Italy and chocolate a la taza served in Spain, and the thinner hot cocoa consumed in the United States. Prepared hot chocolate can be purchased from a range of establishments, including cafeterias, fast food restaurants, coffeehouses and teahouses. Powdered hot chocolate mixes, which can be added to boiling water or hot milk to make the drink at home, are sold at grocery stores and online. Tea Tea, the second most consumed drink in the world, is produced from infusing dried leaves of the camellia sinensis shrub, in boiling water. There are many ways in which tea is prepared for consumption: lemon or milk | In addition to their basic function of satisfying thirst, drinks play important roles in human culture. Common types of drinks include plain drinking water, milk, juice, smoothies and soft drinks. Traditionally warm beverages include coffee, tea, and hot chocolate. Caffeinated drinks that contain the stimulant caffeine have a long history. In addition, alcoholic drinks such as wine, beer, and liquor, which contain the drug ethanol, have been part of human culture for more than 8,000 years. Non-alcoholic drinks often signify drinks that would normally contain alcohol, such as beer, wine and cocktails, but are made with a sufficiently low concentration of alcohol by volume. The category includes drinks that have undergone an alcohol removal process such as non-alcoholic beers and de-alcoholized wines. Biology When the human body becomes dehydrated, a person experiences thirst. This craving of fluids results in an instinctive need to drink. Thirst is regulated by the hypothalamus in response to subtle changes in the body's electrolyte levels, and also as a result of changes in the volume of blood circulating. The complete deprivation of drinks (that is, water) will result in death faster than the removal of any other substance besides oxygen. Water and milk have been basic drinks throughout history. As water is essential for life, it has also been the carrier of many diseases. As society developed, techniques were discovered to create alcoholic drinks from the plants that were available in different areas. The earliest archaeological evidence of wine production yet found has been at sites in Georgia ( BCE) and Iran ( BCE). Beer may have been known in Neolithic Europe as far back as 3000 BCE, and was mainly brewed on a domestic scale. The invention of beer (and bread) has been argued to be responsible for humanity's ability to develop technology and build civilization. Tea likely originated in Yunnan, China, during the Shang Dynasty (1500 BCE–1046 BCE) as a medicinal drink. History Drinking has been a large part of socialising throughout the centuries. In Ancient Greece, a social gathering for the purpose of drinking was known as a symposium, where watered down wine would be drunk. The purpose of these gatherings could be anything from serious discussions to direct indulgence. In Ancient Rome, a similar concept of a convivium took place regularly. Many early societies considered alcohol a gift from the gods, leading to the creation of gods such as Dionysus. Other religions forbid, discourage, or restrict the drinking of alcoholic drinks for various reasons. In some regions with a dominant religion the production, sale, and consumption of alcoholic drinks is forbidden to everybody, regardless of religion. Toasting is a method of honouring a person or wishing good will by taking a drink. Another tradition is that of the loving cup, at weddings or other celebrations such as sports victories a group will share a drink in a large receptacle, shared by everyone until empty. In East Africa and Yemen, coffee was used in native religious ceremonies. As these ceremonies conflicted with the beliefs of the Christian church, the Ethiopian Church banned the secular consumption of coffee until the reign of Emperor Menelik II. The drink was also banned in Ottoman Turkey during the 17th century for political reasons and was associated with rebellious political activities in Europe. Production A drink is a form of liquid which has been prepared for human consumption. The preparation can include a number of different steps, some prior to transport, others immediately prior to consumption. Purification of water Water is the chief constituent in all drinks, and the primary ingredient in most. Water is purified prior to drinking. Methods for purification include filtration and the addition of chemicals, such as chlorination. The importance of purified water is highlighted by the World Health Organization, who point out 94% of deaths from diarrhea – the third biggest cause of infectious death worldwide at 1.8 million annually – could be prevented by improving the quality of the victim's environment, particularly safe water. Pasteurisation Pasteurisation is the process of heating a liquid for a period of time at a specified temperature, then immediately cooling. The process reduces the growth of microorganisms within the liquid, thereby increasing the time before spoilage. It is primarily used on milk, which prior to pasteurisation is commonly infected with pathogenic bacteria and therefore is more likely than any other part of the common diet in the developed world to cause illness. Juicing The process of extracting juice from fruits and vegetables can take a number of forms. Simple crushing of most fruits will provide a significant amount of liquid, though a more intense pressure can be applied to get the maximum amount of juice from the fruit. Both crushing and pressing are processes used in the production of wine. Infusion Infusion is the process of extracting flavours from plant material by allowing the material to remain suspended within water. This process is used in the production of teas, herbal teas and can be used to prepare coffee (when using a coffee press). Percolation The name is derived from the word "percolate" which means to cause (a solvent) to pass through a permeable substance especially for extracting a soluble constituent. In the case of coffee-brewing the solvent is water, the permeable substance is the coffee grounds, and the soluble constituents are the chemical compounds that give coffee its color, taste, aroma, and stimulating properties. Carbonation Carbonation is the process of dissolving carbon dioxide into a liquid, such as water. Fermentation Fermentation is a metabolic process that converts sugar to ethanol. Fermentation has been used by humans for the production of drinks since the Neolithic age. In winemaking, grape juice is combined with yeast in an anaerobic environment to allow the fermentation. The amount of sugar in the wine and the length of time given for fermentation determine the alcohol level and the sweetness of the wine. When brewing beer, there are four primary ingredients – water, grain, yeast and hops. The grain is encouraged to germinate by soaking and drying in heat, a process known as malting. It is then milled before soaking again to create the sugars needed for fermentation. This process is known as mashing. Hops are added for flavouring, then the yeast is added to the mixture (now called wort) to start the fermentation process. Distillation Distillation is a method of separating mixtures based on differences in volatility of components in a boiling liquid mixture. It is one of the methods used in the purification of water. It is also a method of producing spirits from milder alcoholic drinks. Mixing An alcoholic mixed drink that contains two or more ingredients is referred to as a cocktail. Cocktails were originally a mixture of spirits, sugar, water, and bitters. The term is now often used for almost any mixed drink that contains alcohol, including mixers, mixed shots, etc. A cocktail today usually contains one or more kinds of spirit and one or more mixers, such as soda or fruit juice. Additional ingredients may be sugar, honey, milk, cream, and various herbs. Type Non-alcoholic drinks A non-alcoholic drink is one that contains little or no alcohol. This category includes low-alcohol beer, non-alcoholic wine, and apple cider if they contain a sufficiently low concentration of alcohol by volume (ABV). The exact definition of what is "non-alcoholic" and what is not depends on local laws: in the United Kingdom, "alcohol-free beer" is under 0.05% ABV, "de-alcoholised beer" is under 0.5%, while "low-alcohol beer" can contain no more than 1.2% ABV.

Espírito Santo). Dill is found ubiquitously in Santa Maria, yet, is rare in the other Azorean Islands. In Sweden, dill is a common spice or herb. The top of fully grown dill is called krondill (crown dill); this is used when cooking crayfish. The krondill is put into the water after the crayfish is boiled, but still in hot and salt water. Then the entire dish is refrigerated for at least 24 hours before being served (with toasted bread and butter). Krondill also is used for pickles, vodka, not wine, sugar, and krondill. After a month or two of fermentation, the cucumber pickles are ready to eat, for instance, with pork, brown sauce, and potatoes, as a "sweetener". The thinner part of dill and young plants may be used with boiled fresh potatoes (especially the first potatoes of the year, "new potatoes", which usually are small and have a very thin skin). In salads it is used together with, or instead, of other green herbs, such as parsley, chives, and basil. It often is paired up with chives when used in food. Dill often is used to flavour fish and seafood in Sweden, for example, gravlax and various herring pickles, among them the traditional, sill i dill (literally "herring in dill"). In contrast to the various fish dishes flavoured with dill, there is also a traditional Swedish dish called, dillkött, which is a meaty stew flavoured with dill. The dish commonly contains pieces of veal or lamb that are boiled until tender and then served together with a vinegary dill sauce. Dill seeds may be used in breads or akvavit. A newer, non-traditional use of dill is to pair it with chives as a flavouring for potato chips. These are called "dillchips" and are quite popular in Sweden. Asian and Middle Eastern cooking In Iran, dill is known as shevid and sometimes, is used with rice and called shevid-polo. It also is used in Iranian aash recipes, and similarly, is called in Persian. In India, dill is known as "Sholpa" in Bengali, (शेपू) in Marathi and Konkani, in Hindi, or in Punjabi. In Telugu, it is called Soa-kura (herb greens). It also is called (ಸಬ್ಬಸಿಗೆ ಸೊಪ್ಪು) in Kannada. In Tamil it is known as (சதகுப்பி). In Malayalam, it is ചതകുപ്പ () or (). In Sanskrit, this herb is called . In Gujarati, it is known as (સૂવા). In India, dill is prepared in the manner of yellow moong dal, as a main-course dish. It is considered to have very good antiflatulent properties, so it is used as mukhwas, or an after-meal digestive. Traditionally, it is given to mothers immediately after childbirth. In the state of Uttar Pradesh in India, a small amount of fresh dill is cooked along with cut potatoes and fresh fenugreek leaves (Hindi आलू-मेथी-सोया). In Manipur, dill, locally known as , is an essential ingredient of – a traditional Manipuri dish made with fermented soybean and rice. In Laos and parts of northern Thailand, dill is known in English as Lao coriander ( or ), and served as a side with salad yum or papaya salad. In the Lao language, it is called phak see, and in Thai, it is known as phak chee Lao. In Lao cuisine, Lao coriander is used extensively in traditional Lao dishes such as mok pa (steamed fish in banana leaf) and several coconut milk curries that contain fish or prawns. In China dill is called colloquially, huíxiāng (, perfume of Hui people), or more properly shíluó (). It is a common filling in baozi and xianbing and may be used as vegetarian with rice vermicelli, or combined with either meat or eggs. Vegetarian dill baozi are a common part of a Beijing breakfast. In baozi and xianbing, it often is interchangeable with non-bulbing fennel and the term also may refer to fennel, similarly to caraway and coriander leaf, sharing a name in Chinese as well. Dill also may be stir fried as a potherb, often with egg, in the same manner as Chinese chives. It commonly is used in Taiwan as well. In Northern China, Beijing, Inner-Mongolia, Ningxia, Gansu, and Xinjiang, dill seeds commonly are called zīrán (), but also kūmíng (), | water.

In the whole of China, yángchuàn () or yángròu chuàn (), lamb brochette, a speciality from Uyghurs, uses cumin and pepper. In Vietnam, the use of dill in cooking is regional. It is used mainly in northern Vietnamese cuisine. Middle Eastern uses In Arab countries, dill seed, called (grasshopper's eye), is used as a spice in cold dishes such as fattoush and pickles. In Arab countries of the Persian Gulf, dill is called shibint and is used mostly in fish dishes. In Egypt, dillweed is commonly used to flavour cabbage dishes, including mahshi koronb (stuffed cabbage leaves). In Israel, dill weed is used in salads and also to flavour omelettes, often alongside parsley. It is known in Hebrew as (שמיר). Cultivation Successful cultivation requires warm to hot summers with high sunshine levels; even partial shade will reduce the yield substantially. It also prefers rich, well-drained soil. The seeds are viable for three to ten years. The plants are somewhat monocarpic and quickly die after "bolting" (producing seeds). High temperatures may quicken bolting. The seed is harvested by cutting the flower heads off the stalks when the seed is beginning to ripen. The seed heads are placed upside down in a paper bag and left in a warm, dry place for a week. The seeds then separate from the stems easily for storage in an airtight container. These plants, like their fennel and parsley relatives, often are eaten by black swallowtail caterpillars in areas where that species occurs. For this reason, they may be included in some butterfly gardens. Companion planting When used as a companion plant, dill attracts many beneficial insects as the umbrella flower heads go to seed. It makes a good companion plant for cucumbers and broccoli. Tomatoes will benefit from dill when they |
index set I, then In particular if A and B are subspaces of V then If V is finite-dimensional and W is a vector subspace, then after identifying W with its image in the second dual space under the double duality isomorphism . In particular, forming the annihilator is a Galois connection on the lattice of subsets of a finite-dimensional vector space. If W is a subspace of V then the quotient space V/W is a vector space in its own right, and so has a dual. By the first isomorphism theorem, a functional factors through V/W if and only if W is in the kernel of f. There is thus an isomorphism As a particular consequence, if V is a direct sum of two subspaces A and B, then V∗ is a direct sum of A and B. Continuous dual space When dealing with topological vector spaces, the continuous linear functionals from the space into the base field (or ) are particularly important. This gives rise to the notion of the "continuous dual space" or "topological dual" which is a linear subspace of the algebraic dual space , denoted by . For any finite-dimensional normed vector space or topological vector space, such as Euclidean n-space, the continuous dual and the algebraic dual coincide. This is however false for any infinite-dimensional normed space, as shown by the example of discontinuous linear maps. Nevertheless, in the theory of topological vector spaces the terms "continuous dual space" and "topological dual space" are often replaced by "dual space". For a topological vector space its continuous dual space, or topological dual space, or just dual space (in the sense of the theory of topological vector spaces) is defined as the space of all continuous linear functionals . Properties If is a Hausdorff topological vector space (TVS), then the continuous dual space of is identical to the continuous dual space of the completion of . Topologies on the dual There is a standard construction for introducing a topology on the continuous dual of a topological vector space . Fix a collection of bounded subsets of . This gives the topology on of uniform convergence on sets from or what is the same thing, the topology generated by seminorms of the form where is a continuous linear functional on , and runs over the class This means that a net of functionals tends to a functional in if and only if Usually (but not necessarily) the class is supposed to satisfy the following conditions: Each point of belongs to some set : Each two sets and are contained in some set : is closed under the operation of multiplication by scalars: If these requirements are fulfilled then the corresponding topology on is Hausdorff and the sets form its local base. Here are the three most important special cases. The strong topology on is the topology of uniform convergence on bounded subsets in (so here can be chosen as the class of all bounded subsets in ). If is a normed vector space (for example, a Banach space or a Hilbert space) then the strong topology on is normed (in fact a Banach space if the field of scalars is complete), with the norm The stereotype topology on is the topology of uniform convergence on totally bounded sets in (so here can be chosen as the class of all totally bounded subsets in ). The weak topology on is the topology of uniform convergence on finite subsets in (so here can be chosen as the class of all finite subsets in ). Each of these three choices of topology on leads to a variant of reflexivity property for topological vector spaces: If is endowed with the strong topology, then the corresponding notion of reflexivity is the standard one: the spaces reflexive in this sense are just called reflexive. If is endowed with the stereotype dual topology, then the corresponding reflexivity is presented in the theory of stereotype spaces: the spaces reflexive in this sense are called stereotype. If is endowed with the weak topology, then the corresponding reflexivity is presented in the theory of dual pairs: the spaces reflexive in this sense are arbitrary (Hausdorff) locally convex spaces with the weak topology. Examples Let 1 < p < ∞ be a real number and consider the Banach space ℓ p of all sequences for which Define the number q by . Then the continuous dual of ℓ p is naturally identified with ℓ q: given an element , the corresponding element of is the sequence where denotes the sequence whose -th term is 1 and all others are zero. Conversely, given an element , the corresponding continuous linear functional on is defined by for all (see Hölder's inequality). In a similar manner, the continuous dual of is naturally identified with (the space of bounded sequences). Furthermore, the continuous duals of the Banach spaces c (consisting of all convergent sequences, with the supremum norm) and c0 (the sequences converging to zero) are both naturally identified with . By the Riesz representation theorem, the continuous dual of a Hilbert space is again a Hilbert space which is anti-isomorphic to the original space. This gives rise to the bra–ket notation used by physicists in the mathematical formulation of quantum mechanics. By the Riesz–Markov–Kakutani representation theorem, the continuous dual of certain spaces of continuous functions can be described using measures. Transpose of a continuous linear map If is a continuous linear map between two topological vector spaces, then the (continuous) transpose is defined by the same formula as before: The resulting functional is in . The assignment produces a linear map between the space of continuous linear maps from V to W and the space of linear maps from to . When T and U are composable continuous linear maps, then When V and W are normed spaces, the norm of the transpose in is equal to that of T in . Several properties of transposition depend upon the Hahn–Banach theorem. For example, the bounded linear map T has dense range if and only if the transpose is injective. When T is a compact linear map between two Banach spaces V and W, then the transpose is compact. This can be proved using the Arzelà–Ascoli theorem. When V is a Hilbert space, there is an antilinear isomorphism iV from V onto its continuous dual . For every bounded linear map T on V, the transpose and the adjoint operators are linked by When T is a continuous linear map between two topological vector spaces V and W, then the transpose is continuous when and are equipped with"compatible" topologies: for example, when for and , both duals have the strong topology of uniform convergence on bounded sets of X, or both have the weak-∗ topology of pointwise convergence on X. The transpose is continuous from to , or from to . Annihilators Assume that W is a closed linear subspace of a normed space V, and consider the annihilator of W in , Then, the dual of the quotient can be identified with W⊥, and the dual of W can be identified with the quotient . Indeed, let P denote the canonical surjection from V onto the quotient ; then, the transpose is an isometric isomorphism from into , with range equal to W⊥. If j denotes the injection map from W into V, then the kernel of the transpose is the annihilator of W: and it follows from the Hahn–Banach theorem that induces an isometric isomorphism . Further properties If the dual of a normed space is separable, then so is the space itself. The converse is not true: for example, the space is separable, but its dual is not. Double dual In analogy with the case of the algebraic double dual, there is always a naturally defined continuous linear operator from a normed space V into its continuous double dual , defined by As a consequence of the | an archetypal example of a natural isomorphism. Infinite-dimensional Hilbert spaces are not a counterexample to this, as they are isomorphic to their continuous double duals, not to their algebraic double duals. Transpose of a linear map If is a linear map, then the transpose (or dual) is defined by for every . The resulting functional in is called the pullback of along . The following identity holds for all and : where the bracket [·,·] on the left is the natural pairing of V with its dual space, and that on the right is the natural pairing of W with its dual. This identity characterizes the transpose, and is formally similar to the definition of the adjoint. The assignment produces an injective linear map between the space of linear operators from V to W and the space of linear operators from W to V; this homomorphism is an isomorphism if and only if W is finite-dimensional. If then the space of linear maps is actually an algebra under composition of maps, and the assignment is then an antihomomorphism of algebras, meaning that . In the language of category theory, taking the dual of vector spaces and the transpose of linear maps is therefore a contravariant functor from the category of vector spaces over F to itself. It is possible to identify (f) with f using the natural injection into the double dual. If the linear map f is represented by the matrix A with respect to two bases of V and W, then f is represented by the transpose matrix AT with respect to the dual bases of W and V, hence the name. Alternatively, as f is represented by A acting on the left on column vectors, f is represented by the same matrix acting on the right on row vectors. These points of view are related by the canonical inner product on Rn, which identifies the space of column vectors with the dual space of row vectors. Quotient spaces and annihilators Let S be a subset of V. The annihilator of S in V∗, denoted here S, is the collection of linear functionals such that for all . That is, S consists of all linear functionals such that the restriction to S vanishes: . Within finite dimensional vector spaces, the annihilator is dual to (isomorphic to) the orthogonal complement. The annihilator of a subset is itself a vector space. The annihilator of the zero vector is the whole dual space: , and the annihilator of the whole space is just the zero covector: . Furthermore, the assignment of an annihilator to a subset of V reverses inclusions, so that if , then If A and B are two subsets of V then and equality holds provided V is finite-dimensional. If Ai is any family of subsets of V indexed by i belonging to some index set I, then In particular if A and B are subspaces of V then If V is finite-dimensional and W is a vector subspace, then after identifying W with its image in the second dual space under the double duality isomorphism . In particular, forming the annihilator is a Galois connection on the lattice of subsets of a finite-dimensional vector space. If W is a subspace of V then the quotient space V/W is a vector space in its own right, and so has a dual. By the first isomorphism theorem, a functional factors through V/W if and only if W is in the kernel of f. There is thus an isomorphism As a particular consequence, if V is a direct sum of two subspaces A and B, then V∗ is a direct sum of A and B.

in developing Dianetics was abreaction therapy. Abreaction is a psychoanalytical term that means bringing to consciousness, and thus adequate expression, material that has been unconscious. "It includes not only the recollection of forgotten memories and experience, but also their reliving with appropriate emotional display and discharge of effect. This process is usually facilitated by the patient's gaining awareness of the causal relationship between the previously undischarged emotion and his symptoms." According to Hubbard, before Dianetics psychotherapists had dealt with very light and superficial incidents (e.g. an incident that reminds the patient of a moment of loss), but with Dianetic therapy, the patient could actually erase moments of pain and unconsciousness. He emphasized: "The discovery of the engram is entirely the property of Dianetics. Methods of its erasure are also owned entirely by Dianetics". While 1950 style Dianetics was in some respects similar to older therapies, with the development of New Era Dianetics in 1978, the similarity vanished. New Era Dianetics uses an E-Meter and a rote procedure for running chains of related traumatic incidents. Dianetics clarifies the understanding of psychosomatic illness in terms of predisposition, precipitation, and prolongation. With the use of Dianetics techniques, Hubbard claimed, the reactive mind could be processed and all stored engrams could be refiled as experience. The central technique was "auditing", a two-person question-and-answer therapy designed to isolate and dissipate engrams (or "mental masses"). An auditor addresses questions to a subject, observes and records the subject's responses, and returns repeatedly to experiences or areas under discussion that appear painful until the troubling experience has been identified and confronted. Through repeated applications of this method, the reactive mind could be "cleared" of its content having outlived its usefulness in the process of evolution; a person who has completed this process would be "Clear". The benefits of going Clear, according to Hubbard, were dramatic. A Clear would have no compulsions, repressions, psychoses or neuroses, and would enjoy a near-perfect memory as well as a rise in IQ of as much as 50 points. He also claimed that "the atheist is activated by engrams as thoroughly as the zealot". He further claimed that widespread application of Dianetics would result in "A world without insanity, without criminals and without war." One of the key ideas of Dianetics, according to Hubbard, is the fundamental existential command to survive. According to Hugh B. Urban, this would serve as the foundation of a big part of later Scientology. According to the Scientology journal The Auditor, the total number of "Clears" as of May 2006 stands at 50,311. Procedure in practice The procedure of Dianetics therapy (known as auditing) is a two-person activity. One person, the "auditor", guides the other person, the "pre-clear". The pre-Clear's job is to look at the mind and talk to the auditor. The auditor acknowledges what the pre-Clear says and controls the process so the pre-Clear may put his full attention on his work. The auditor and pre-Clear sit down in chairs facing each other. The process then follows in eleven distinct steps: 1. The auditor assures the pre-Clear that he will be fully aware of everything that happens during the session. 2. The pre-Clear is instructed to close his eyes for the session, entering a state of "dianetic reverie", signified by "a tremble of the lashes". During the session, the preclear remains in full possession of his will and retains full recall thereafter. 3. The auditor installs a "canceller", an instruction intended to absolutely cancel any form of positive suggestion that could accidentally occur. This is done by saying "In the future, when I utter the word 'cancelled,' everything I have said to you while you are in a therapy session will be cancelled and will have no force with you. Any suggestion I may have made to you will be without force when I say the word 'cancelled.' Do you understand?" 4. The auditor then asks the pre-Clear to locate an exact record of something that happened to the pre-Clear in his past: "Locate an incident that you feel you can comfortably face." 5. The pre-Clear is invited by the auditor to "Go through the incident and say what is happening as you go along." 6a. The auditor instructs the pre-Clear to recall as much as possible of the incident, going over it several times "until the pre-Clear is cheerful about it". 6b. When the pre-Clear is cheerful about an incident, the auditor instructs the pre-Clear to locate another incident: "Let's find another incident that you feel you can comfortably face." The process outlined at steps 5 and 6a then repeats until the auditing session's time limit (usually two hours or so) is reached. 7. The pre-Clear is then instructed to "return to present time". 8. The auditor checks to make sure that the pre-Clear feels himself to be in "present time", i.e., not still recalling a past incident. 9. The auditor gives the pre-Clear the canceller word: "Very good. Cancelled." 10. The auditor tells the pre-Clear to feel alert and return to full awareness of his surroundings: "When I count from five to one and snap my fingers you will feel alert. Five, four, three, two, one." (snaps fingers) Auditing sessions are supposedly kept confidential. A few transcripts of auditing sessions with confidential information removed have been published as demonstration examples. Some extracts can be found in J.A. Winter's book Dianetics: A Doctor's Report. Other, more comprehensive, transcripts of auditing sessions carried out by Hubbard himself can be found in volume 1 of the Research & Discovery Series (Bridge Publications, 1980). Examples of public group processing sessions can be found throughout the Congresses lecture series. According to Hubbard, auditing enables the pre-Clear to "contact" and "release" engrams stored in the reactive mind, relieving him of the physical and mental aberrations connected with them. The pre-Clear is asked to inspect and familiarize himself with the exact details of his own experience; the auditor may not tell him anything about his case or evaluate any of the information the pre-Clear finds. Therapeutic claims In August 1950, amidst the success of Dianetics, Hubbard held a demonstration in Los Angeles' Shrine Auditorium where he presented a young woman called Sonya Bianca (a pseudonym) to a large audience including many reporters and photographers as "the world's first Clear". Despite Hubbard's claim that she had "full and perfect recall of every moment of her life", Bianca proved unable to answer questions from the audience testing her memory and analytical abilities, including the question of the color of Hubbard's tie. Hubbard explained Bianca's failure to display her promised powers of recall to the audience by saying that he had used the word "now" in calling her to the stage, and thus inadvertently froze her in "present time", which blocked her abilities. Later, in the late 1950s, Hubbard would claim that several people had reached the state of Clear by the time he presented Bianca as the world's first; these others, Hubbard said, he had successfully cleared in the late 1940s while working incognito in Hollywood posing as a swami. In 1966, Hubbard declared South African Scientologist John McMaster to be the first true Clear. Hubbard claimed, in an interview with The New York Times in November 1950, that "he had already submitted proof of claims made in the book to a number of scientists and associations." He added that the public as well as proper organizations were entitled to such proof and that he was ready and willing to give such proof in detail. In January 1951, the Hubbard Dianetic Research Foundation of Elizabeth, New Jersey, published Dianetic Processing: A Brief Survey of Research Projects and Preliminary Results, a booklet providing the results of psychometric tests conducted on 88 people undergoing Dianetics therapy. It presents case histories and a number of X-ray plates to support claims that Dianetics had cured "aberrations" including manic depression, asthma, arthritis, colitis and "overt homosexuality", and that after Dianetic processing, test subjects experienced significantly increased scores on a standardized IQ test. The report's subjects are not identified by name, but one of them is clearly Hubbard himself ("Case 1080A, R. L."). The authors provide no qualifications, although they are described in Hubbard's book Science of Survival (where some results of the same study were reprinted) as psychotherapists. Critics of Dianetics are skeptical of this study, both because of the bias of the source and because the researchers appear to ascribe all physical benefits to Dianetics without considering possible outside factors; in other words, the report lacks any scientific controls. J.A. Winter, M.D., originally an associate of Hubbard and an early adopter of Dianetics, had by the end of 1950 cut his ties with Hubbard and written an account of his personal experiences with Dianetics. He described Hubbard as "absolutistic and authoritarian", and criticized the Hubbard Dianetic Research Foundation for failing to undertake "precise scientific research into the functioning of the mind". He also recommended that auditing be done by experts only and that it was dangerous for laymen to audit each other. Hubbard writes: "Again, Dianetics is not being released to a profession, for no profession could encompass it." Scientific rejection Hubbard's original book on Dianetics attracted highly critical reviews from science and medical writers and organizations. The American Psychological Association passed a resolution in 1950 calling "attention to the fact that these claims are not supported by empirical evidence of the sort required for the establishment of scientific generalizations." Subsequently, Dianetics has achieved no acceptance as a scientific theory, and scientists cite Dianetics as an example of a pseudoscience. Few scientific investigations into the effectiveness of Dianetics have been published. Professor John A. Lee states in his 1970 evaluation of Dianetics: The MEDLINE database records two independent scientific studies on Dianetics, both conducted in the 1950s under the auspices of New York University. Harvey Jay Fischer tested Dianetic therapy against three claims made by proponents and found it does not effect any significant changes in intellectual functioning, mathematical ability, or the degree of personality conflicts; Jack Fox tested Hubbard's thesis regarding recall of engrams, with the assistance of the Dianetic Research Foundation, and could not substantiate it. Commentators from a variety of backgrounds have described Dianetics as an example of pseudoscience. For example, philosophy professor Robert Carroll points to Dianetics' lack of empirical evidence: The validity and practice of auditing have been questioned by a variety of non-Scientologist commentators. Commenting on the example cited by Winter, the science writer Martin Gardner asserts that "nothing could be clearer from the above dialogue than the fact that the dianetic explanation for the headache existed only in the mind of the therapist, and that it was with considerable difficulty that the patient was maneuvered into accepting it." Other critics and medical experts have suggested that Dianetic auditing is a form of hypnosis. Hubbard, who had previously used hypnosis for entertainment purposes, strongly denied this connection and cautioned against hypnosis in Dianetics auditing. Professor Richard J. Ofshe, a leading | years previously that traumas with similar content join together in "chains", embedded in the unconscious mind, to cause irrational responses in the individual. Such a chain would be relieved by inducing the patient to remember the earliest trauma, "with an accompanying expression of emotion." According to Bent Corydon, Hubbard created the illusion that Dianetics was the first psychotherapy to address traumatic experiences in their own time, but others had done so as standard procedure. One treatment method Hubbard drew from in developing Dianetics was abreaction therapy. Abreaction is a psychoanalytical term that means bringing to consciousness, and thus adequate expression, material that has been unconscious. "It includes not only the recollection of forgotten memories and experience, but also their reliving with appropriate emotional display and discharge of effect. This process is usually facilitated by the patient's gaining awareness of the causal relationship between the previously undischarged emotion and his symptoms." According to Hubbard, before Dianetics psychotherapists had dealt with very light and superficial incidents (e.g. an incident that reminds the patient of a moment of loss), but with Dianetic therapy, the patient could actually erase moments of pain and unconsciousness. He emphasized: "The discovery of the engram is entirely the property of Dianetics. Methods of its erasure are also owned entirely by Dianetics". While 1950 style Dianetics was in some respects similar to older therapies, with the development of New Era Dianetics in 1978, the similarity vanished. New Era Dianetics uses an E-Meter and a rote procedure for running chains of related traumatic incidents. Dianetics clarifies the understanding of psychosomatic illness in terms of predisposition, precipitation, and prolongation. With the use of Dianetics techniques, Hubbard claimed, the reactive mind could be processed and all stored engrams could be refiled as experience. The central technique was "auditing", a two-person question-and-answer therapy designed to isolate and dissipate engrams (or "mental masses"). An auditor addresses questions to a subject, observes and records the subject's responses, and returns repeatedly to experiences or areas under discussion that appear painful until the troubling experience has been identified and confronted. Through repeated applications of this method, the reactive mind could be "cleared" of its content having outlived its usefulness in the process of evolution; a person who has completed this process would be "Clear". The benefits of going Clear, according to Hubbard, were dramatic. A Clear would have no compulsions, repressions, psychoses or neuroses, and would enjoy a near-perfect memory as well as a rise in IQ of as much as 50 points. He also claimed that "the atheist is activated by engrams as thoroughly as the zealot". He further claimed that widespread application of Dianetics would result in "A world without insanity, without criminals and without war." One of the key ideas of Dianetics, according to Hubbard, is the fundamental existential command to survive. According to Hugh B. Urban, this would serve as the foundation of a big part of later Scientology. According to the Scientology journal The Auditor, the total number of "Clears" as of May 2006 stands at 50,311. Procedure in practice The procedure of Dianetics therapy (known as auditing) is a two-person activity. One person, the "auditor", guides the other person, the "pre-clear". The pre-Clear's job is to look at the mind and talk to the auditor. The auditor acknowledges what the pre-Clear says and controls the process so the pre-Clear may put his full attention on his work. The auditor and pre-Clear sit down in chairs facing each other. The process then follows in eleven distinct steps: 1. The auditor assures the pre-Clear that he will be fully aware of everything that happens during the session. 2. The pre-Clear is instructed to close his eyes for the session, entering a state of "dianetic reverie", signified by "a tremble of the lashes". During the session, the preclear remains in full possession of his will and retains full recall thereafter. 3. The auditor installs a "canceller", an instruction intended to absolutely cancel any form of positive suggestion that could accidentally occur. This is done by saying "In the future, when I utter the word 'cancelled,' everything I have said to you while you are in a therapy session will be cancelled and will have no force with you. Any suggestion I may have made to you will be without force when I say the word 'cancelled.' Do you understand?" 4. The auditor then asks the pre-Clear to locate an exact record of something that happened to the pre-Clear in his past: "Locate an incident that you feel you can comfortably face." 5. The pre-Clear is invited by the auditor to "Go through the incident and say what is happening as you go along." 6a. The auditor instructs the pre-Clear to recall as much as possible of the incident, going over it several times "until the pre-Clear is cheerful about it". 6b. When the pre-Clear is cheerful about an incident, the auditor instructs the pre-Clear to locate another incident: "Let's find another incident that you feel you can comfortably face." The process outlined at steps 5 and 6a then repeats until the auditing session's time limit (usually two hours or so) is reached. 7. The pre-Clear is then instructed to "return to present time". 8. The auditor checks to make sure that the pre-Clear feels himself to be in "present time", i.e., not still recalling a past incident. 9. The auditor gives the pre-Clear the canceller word: "Very good. Cancelled." 10. The auditor tells the pre-Clear to feel alert and return to full awareness of his surroundings: "When I count from five to one and snap my fingers you will feel alert. Five, four, three, two, one." (snaps fingers) Auditing sessions are supposedly kept confidential. A few transcripts of auditing sessions with confidential information removed have been published as demonstration examples. Some extracts can be found in J.A. Winter's book Dianetics: A Doctor's Report. Other, more comprehensive, transcripts of auditing sessions carried out by Hubbard himself can be found in volume 1 of the Research & Discovery Series (Bridge Publications, 1980). Examples of public group processing sessions can be found throughout the Congresses lecture series. According to Hubbard, auditing enables the pre-Clear to "contact" and "release" engrams stored in the reactive mind, relieving him of the physical and mental aberrations connected with them. The pre-Clear is asked to inspect and familiarize himself with the exact details of his own experience; the auditor may not tell him anything about his case or evaluate any of the information the pre-Clear finds. Therapeutic claims In August 1950, amidst the success of Dianetics, Hubbard held a demonstration in Los Angeles' Shrine Auditorium where he presented a young woman called Sonya Bianca (a pseudonym) to a large audience including many reporters and photographers as "the world's first Clear". Despite Hubbard's claim that she had "full and perfect recall of every moment of her life", Bianca proved unable to answer questions from the audience testing her memory and analytical abilities, including the question of the color of Hubbard's tie. Hubbard explained Bianca's failure to display her promised powers of recall to the audience by saying that he had used the word "now" in calling her to the stage, and thus inadvertently froze her in "present time", which blocked her abilities. Later, in the late 1950s, Hubbard would claim that several people had reached the state of Clear by the time he presented Bianca as the world's first; these others, Hubbard said, he had successfully cleared in the late 1940s while working incognito in Hollywood posing as a swami. In 1966, Hubbard declared South African Scientologist John McMaster to be the first true Clear. Hubbard claimed, in an interview with The New York Times in November 1950, that "he had already submitted proof of claims made in the book to a number of scientists and associations." He added that the public as well as proper organizations were entitled to such proof and that he was ready and willing to give such proof in detail. In January 1951, the Hubbard Dianetic Research Foundation of Elizabeth, New Jersey, published Dianetic Processing: A Brief Survey of Research Projects and Preliminary Results, a booklet providing the results of psychometric tests conducted on 88 people undergoing Dianetics therapy. It presents case histories and a number of X-ray plates to support claims that Dianetics had cured "aberrations" including manic depression, asthma, arthritis, colitis and "overt homosexuality", and that after Dianetic processing, test subjects experienced significantly increased scores on a standardized IQ test. The report's subjects are not identified by name, but one of them is clearly Hubbard himself ("Case 1080A, R. L."). The authors provide no qualifications, although they are described in Hubbard's book Science of Survival (where some results of the same study were reprinted) as psychotherapists. Critics of Dianetics are skeptical of this study, both because of the bias of the source and because the researchers appear to ascribe all physical benefits to Dianetics without considering possible outside factors; in other words, the report lacks any scientific controls. J.A. Winter, M.D., originally an associate of Hubbard and an early adopter of Dianetics, had by the end of 1950 cut his ties with Hubbard and written an account of his personal experiences with Dianetics. He described Hubbard as "absolutistic and authoritarian", and criticized the Hubbard Dianetic Research Foundation for failing to undertake "precise scientific research into the functioning of the mind". He also recommended that auditing be done by experts only and that it was dangerous for laymen to audit each other. Hubbard writes: "Again, Dianetics is not being released to a profession, for no profession could encompass it." Scientific rejection Hubbard's original book on Dianetics attracted highly critical reviews from science and medical writers and organizations. The American Psychological Association passed a resolution in 1950 calling "attention to the fact that these claims are not supported by empirical evidence of the sort required for the establishment of scientific generalizations." Subsequently, Dianetics has achieved no acceptance as a scientific theory, and scientists cite Dianetics as an example of a pseudoscience. Few scientific investigations into the effectiveness of Dianetics have been published. Professor John A. Lee states in his 1970 evaluation of Dianetics: The MEDLINE database records two independent scientific studies on Dianetics, both conducted in the 1950s under the auspices of New York University. Harvey Jay Fischer tested Dianetic therapy against three claims made by proponents and found it does not effect any significant changes in intellectual functioning, mathematical ability, or the degree of personality conflicts; Jack Fox tested Hubbard's thesis regarding recall of engrams, with the assistance of the Dianetic Research Foundation, and could not substantiate it. Commentators from a variety of backgrounds have described Dianetics as an example of pseudoscience. For example, philosophy professor Robert Carroll points to Dianetics' lack of empirical evidence: The validity and practice of auditing have been questioned by a variety of non-Scientologist commentators. Commenting on the example cited by Winter, the science writer Martin Gardner asserts that "nothing could be clearer from the above dialogue than the fact that the dianetic explanation for the headache existed only in the mind of the therapist, and that it was with considerable difficulty that the patient was maneuvered into accepting it." Other critics and medical experts have suggested that Dianetic auditing is a form of hypnosis. Hubbard, who had previously used hypnosis for entertainment purposes, strongly denied this connection and cautioned against hypnosis in Dianetics auditing. Professor Richard J. Ofshe, a leading expert on false memories, suggests that the feeling of well-being reported by pre-Clear at the end of an auditing session may be induced by post-hypnotic suggestion. Other researchers have identified quotations in Hubbard's work suggesting evidence that false memories were created in Dianetics, specifically in the form of birth and pre-birth memories. According to an article by physician Martin Gumpert, "Hubbard's concept of psychosomatic disease is definitely wrong. Psychosomatic ailments are not simply caused by emotional disturbances: they are diseases in which the emotional and the organic factor are closely involved and interdependent."

an operational data store and may require data cleansing for additional operations to ensure data quality before it is used in the DW for reporting. Extract, transform, load (ETL) and extract, load, transform (ELT) are the two main approaches used to build a data warehouse system. ETL-based data warehousing The typical extract, transform, load (ETL)-based data warehouse uses staging, data integration, and access layers to house its key functions. The staging layer or staging database stores raw data extracted from each of the disparate source data systems. The integration layer integrates the disparate data sets by transforming the data from the staging layer often storing this transformed data in an operational data store (ODS) database. The integrated data are then moved to yet another database, often called the data warehouse database, where the data is arranged into hierarchical groups, often called dimensions, and into facts and aggregate facts. The combination of facts and dimensions is sometimes called a star schema. The access layer helps users retrieve data. The main source of the data is cleansed, transformed, catalogued, and made available for use by managers and other business professionals for data mining, online analytical processing, market research and decision support. However, the means to retrieve and analyze data, to extract, transform, and load data, and to manage the data dictionary are also considered essential components of a data warehousing system. Many references to data warehousing use this broader context. Thus, an expanded definition for data warehousing includes business intelligence tools, tools to extract, transform, and load data into the repository, and tools to manage and retrieve metadata. ELT-based data warehousing ELT-based data warehousing gets rid of a separate ETL tool for data transformation. Instead, it maintains a staging area inside the data warehouse itself. In this approach, data gets extracted from heterogeneous source systems and are then directly loaded into the data warehouse, before any transformation occurs. All necessary transformations are then handled inside the data warehouse itself. Finally, the manipulated data gets loaded into target tables in the same data warehouse. Benefits A data warehouse maintains a copy of information from the source transaction systems. This architectural complexity provides the opportunity to: Integrate data from multiple sources into a single database and data model. More congregation of data to single database so a single query engine can be used to present data in an ODS. Mitigate the problem of database isolation level lock contention in transaction processing systems caused by attempts to run large, long-running analysis queries in transaction processing databases. Maintain data history, even if the source transaction systems do not. Integrate data from multiple source systems, enabling a central view across the enterprise. This benefit is always valuable, but particularly so when the organization has grown by merger. Improve data quality, by providing consistent codes and descriptions, flagging or even fixing bad data. Present the organization's information consistently. Provide a single common data model for all data of interest regardless of the data's source. Restructure the data so that it makes sense to the business users. Restructure the data so that it delivers excellent query performance, even for complex analytic queries, without impacting the operational systems. Add value to operational business applications, notably customer relationship management (CRM) systems. Make decision–support queries easier to write. Organize and disambiguate repetitive data Generic The environment for data warehouses and marts includes the following: Source systems that provide data to the warehouse or mart; Data integration technology and processes that are needed to prepare the data for use; Different architectures for storing data in an organization's data warehouse or data marts; Different tools and applications for a variety of users; Metadata, data quality, and governance processes must be in place to ensure that the warehouse or mart meets its purposes. In regards to source systems listed above, R. Kelly Rainer states, "A common source for the data in data warehouses is the company's operational databases, which can be relational databases". Regarding data integration, Rainer states, "It is necessary to extract data from source systems, transform them, and load them into a data mart or warehouse". Rainer discusses storing data in an organization's data warehouse or data marts. Metadata is data about data. "IT personnel need information about data sources; database, table, and column names; refresh schedules; and data usage measures". Today, the most successful companies are those that can respond quickly and flexibly to market changes and opportunities. A key to this response is the effective and efficient use of data and information by analysts and managers. A "data warehouse" is a repository of historical data that is organized by the subject to support decision-makers in the organization. Once data is stored in a data mart or warehouse, it can be accessed. Related systems (data mart, OLAP, OLTP, predictive analytics) A data mart is a simple form of a data warehouse that is focused on a single subject (or functional area), hence they draw data from a limited number of sources such as sales, finance or marketing. Data marts are often built and controlled by a single department within an organization. The sources could be internal operational systems, a central data warehouse, or external data. Denormalization is the norm for data modeling techniques in this system. Given that data marts generally cover only a subset of the data contained in a data warehouse, they are often easier and faster to implement. Types of data marts include dependent, independent, and hybrid data marts. Online analytical processing (OLAP) is characterized by a relatively low volume of transactions. Queries are often very complex and involve aggregations. For OLAP systems, response time is an effective measure. OLAP applications are widely used by Data Mining techniques. OLAP databases store aggregated, historical data in multi-dimensional schemas (usually star schemas). OLAP systems typically have a data latency of a few hours, as opposed to data marts, where latency is expected to be closer to one day. The OLAP approach is used to analyze multidimensional data from multiple sources and perspectives. The three basic operations in OLAP are Roll-up (Consolidation), Drill-down, and Slicing & Dicing. Online transaction processing (OLTP) is characterized by a large number of short on-line transactions (INSERT, UPDATE, DELETE). OLTP systems emphasize very fast query processing and maintaining data integrity in multi-access environments. For OLTP systems, effectiveness is measured by the number of transactions per second. OLTP databases contain detailed and current data. The schema used to store transactional databases is the entity model (usually 3NF). Normalization is the norm for data modeling techniques in this system. Predictive analytics is about finding and quantifying hidden patterns in the data using complex mathematical models that can be used to predict future outcomes. Predictive analysis is different from OLAP in that OLAP focuses on historical data analysis and is reactive in nature, while predictive analysis focuses on the future. These systems are also used for customer relationship management (CRM). History | nature, while predictive analysis focuses on the future. These systems are also used for customer relationship management (CRM). History The concept of data warehousing dates back to the late 1980s when IBM researchers Barry Devlin and Paul Murphy developed the "business data warehouse". In essence, the data warehousing concept was intended to provide an architectural model for the flow of data from operational systems to decision support environments. The concept attempted to address the various problems associated with this flow, mainly the high costs associated with it. In the absence of a data warehousing architecture, an enormous amount of redundancy was required to support multiple decision support environments. In larger corporations, it was typical for multiple decision support environments to operate independently. Though each environment served different users, they often required much of the same stored data. The process of gathering, cleaning and integrating data from various sources, usually from long-term existing operational systems (usually referred to as legacy systems), was typically in part replicated for each environment. Moreover, the operational systems were frequently reexamined as new decision support requirements emerged. Often new requirements necessitated gathering, cleaning and integrating new data from "data marts" that was tailored for ready access by users. Additionally, with the publication of The IRM Imperative (Wiley & Sons, 1991) by James M. Kerr, the idea of managing and putting a dollar value on an organization's data resources and then reporting that value as an asset on a balance sheet became popular. In the book, Kerr described a way to populate subject-area databases from data derived from transaction-driven systems to create a storage area where summary data could be further leveraged to inform executive decision-making. This concept served to promote further thinking of how a data warehouse could be developed and managed in a practical way within any enterprise. Key developments in early years of data warehousing: 1960s – General Mills and Dartmouth College, in a joint research project, develop the terms dimensions and facts. 1970s – ACNielsen and IRI provide dimensional data marts for retail sales. 1970s – Bill Inmon begins to define and discuss the term Data Warehouse. 1975 – Sperry Univac introduces MAPPER (MAintain, Prepare, and Produce Executive Reports), a database management and reporting system that includes the world's first 4GL. It is the first platform designed for building Information Centers (a forerunner of contemporary data warehouse technology). 1983 – Teradata introduces the DBC/1012 database computer specifically designed for decision support. 1984 – Metaphor Computer Systems, founded by David Liddle and Don Massaro, releases a hardware/software package and GUI for business users to create a database management and analytic system. 1988 – Barry Devlin and Paul Murphy publish the article "An architecture for a business and information system" where they introduce the term "business data warehouse". 1990 – Red Brick Systems, founded by Ralph Kimball, introduces Red Brick Warehouse, a database management system specifically for data warehousing. 1991 - James M. Kerr authors The IRM Imperative, which suggests data resources could be reported as an asset on a balance sheet, furthering commercial interest in the establishment of data warehouses. 1991 – Prism Solutions, founded by Bill Inmon, introduces Prism Warehouse Manager, software for developing a data warehouse. 1992 – Bill Inmon publishes the book Building the Data Warehouse. 1995 – The Data Warehousing Institute, a for-profit organization that promotes data warehousing, is founded. 1996 – Ralph Kimball publishes the book The Data Warehouse Toolkit. 2000 – Dan Linstedt releases in the public domain the Data vault modeling, conceived in 1990 as an alternative to Inmon and Kimball to provide long-term historical storage of data coming in from multiple operational systems, with emphasis on tracing, auditing and resilience to change of the source data model. 2008 – Bill Inmon, along with Derek Strauss and Genia Neushloss, publishes "DW 2.0: The Architecture for the Next Generation of Data Warehousing", explaining his top-down approach to data warehousing and coining the term, data-warehousing 2.0. 2012 – Bill Inmon develops and makes public technology known as "textual disambiguation". Textual disambiguation applies context to raw text and reformats the raw text and context into a standard data base format. Once raw text is passed through textual disambiguation, it can easily and efficiently be accessed and analyzed by standard business intelligence technology. Textual disambiguation is accomplished through the execution of textual ETL. Textual disambiguation is useful wherever raw text is found, such as in documents, Hadoop, email, and so forth. Information storage Facts A fact is a value, or measurement, which represents a fact about the managed entity or system. Facts, as reported by the reporting entity, are said to be at raw level; e.g., in a mobile telephone system, if a BTS (base transceiver station) receives 1,000 requests for traffic channel allocation, allocates for 820, and rejects the remaining, it would report three facts or measurements to a management system: Facts at the raw level are further aggregated to higher levels in various dimensions to extract more service or business-relevant information from it. These are called aggregates or summaries or aggregated facts. For instance, if there are three BTS in a city, then the facts above can be aggregated from the BTS to the city level in the network dimension. For example: Dimensional versus normalized approach for storage of data There are three or more leading approaches to storing data in a data warehouse – the most important approaches are the dimensional approach and the normalized approach. The dimensional approach refers to Ralph Kimball's approach in which it is stated that the data warehouse should be modeled using a Dimensional Model/star schema. The normalized approach, also called the 3NF model (Third Normal Form), refers to Bill Inmon's approach in which it is stated that the data warehouse should be modeled using an E-R model/normalized model. Dimensional approach In a dimensional approach, transaction data is partitioned into "facts", which are generally numeric transaction data, and "dimensions", which are the reference information that gives context to the facts. For example, a sales transaction can be broken up into facts such as the number of products ordered and the total price paid for the products, and into dimensions such as order date, customer name, product number, order ship-to and bill-to locations, and salesperson responsible for receiving the order. A key advantage of a dimensional approach is that the data warehouse is easier for the user to understand and to use. Also, the retrieval of data from the data warehouse tends to operate very quickly. Dimensional structures are easy to understand for business users, because the structure is divided into measurements/facts and context/dimensions. Facts are related to the organization's business processes and operational system whereas the dimensions surrounding them contain context about the measurement (Kimball, Ralph 2008). Another advantage offered by dimensional model is that it does not involve a relational database every time. Thus, this type of modeling technique is very useful for end-user queries in data warehouse. The model of facts and dimensions can also be understood as a data cube. Where the dimensions are the categorical coordinates in a multi-dimensional cube, the fact is a value corresponding to the coordinates. The main disadvantages of the dimensional approach are the following: To maintain the integrity of facts and dimensions, loading the data warehouse with data from different operational systems is complicated. It is difficult to modify the data warehouse structure if the organization adopting the dimensional approach changes the way in which it does business. Normalized approach In the normalized approach, the data in the data warehouse are stored following, to a degree, database normalization rules. Tables are grouped together by subject areas that reflect general data categories (e.g., data on customers, products, finance, etc.). The normalized structure divides data into entities, which creates several tables in a relational database. When applied in large enterprises the result is dozens of tables that are linked together by a web of joins. Furthermore, each of the created entities is converted into separate physical tables when the database is implemented (Kimball, Ralph 2008). The main advantage of this approach is that it is straightforward to add information into the database. Some disadvantages of this approach are that, because of the number of tables involved, it can be difficult for users to join data from different sources into meaningful information and to access the information without a precise understanding of the sources of data and of the data structure of the data warehouse. Both normalized and dimensional models can be represented in entity-relationship diagrams as both contain joined relational tables. The difference between the two models is the degree of normalization (also known as Normal Forms). These approaches are not mutually exclusive, and there are other approaches. Dimensional approaches can involve normalizing data to a degree (Kimball, Ralph 2008). In Information-Driven Business, Robert Hillard proposes an approach to comparing the two approaches based on the information needs of the business problem. The technique shows that normalized models hold far more information than their dimensional equivalents (even when the same fields are used in both models) but this extra information comes at the cost of usability. The technique measures information quantity in terms of information entropy and usability in terms of the Small Worlds data transformation measure. Design methods Bottom-up design In the bottom-up |

The Devonian Period was a time of great tectonic activity, as Euramerica and Gondwana drew closer together. The continent Euramerica (or Laurussia) was created in the early Devonian by the collision of Laurentia and Baltica, which rotated into the natural dry zone along the Tropic of Capricorn, which is formed as much in Paleozoic times as nowadays by the convergence of two great air-masses, the Hadley cell and the Ferrel cell. In these near-deserts, the Old Red Sandstone sedimentary beds formed, made red by the oxidised iron (hematite) characteristic of drought conditions. Near the equator, the plate of Euramerica and Gondwana were starting to meet, beginning the early stages of the assembling of Pangaea. This activity further raised the northern Appalachian Mountains and formed the Caledonian Mountains in Great Britain and Scandinavia. The west coast of Devonian North America, by contrast, was a passive margin with deep silty embayments, river deltas and estuaries, found today in Idaho and Nevada; an approaching volcanic island arc reached the steep slope of the continental shelf in Late Devonian times and began to uplift deep water deposits, a collision that was the prelude to the mountain-building episode at the beginning of the Carboniferous called the Antler orogeny. Sea levels were high worldwide, and much of the land lay under shallow seas, where tropical reef organisms lived. The deep, enormous Panthalassa (the "universal ocean") covered the rest of the planet. Other minor oceans were the Paleo-Tethys Ocean, Proto-Tethys Ocean, Rheic Ocean, and Ural Ocean (which was closed during the collision with Siberia and Baltica). During the Devonian, Chaitenia, an island arc, accreted to Patagonia. Life Marine biota Sea levels in the Devonian were generally high. Marine faunas continued to be dominated by bryozoa, diverse and abundant brachiopods, the enigmatic hederellids, microconchids and corals. Lily-like crinoids (animals, their resemblance to flowers notwithstanding) were abundant, and trilobites were still fairly common. Among vertebrates, jawless armored fish (ostracoderms) declined in diversity, while the jawed fish (gnathostomes) simultaneously increased in both the sea and fresh water. Armored placoderms were numerous during the lower stages of the Devonian Period and became extinct in the Late Devonian, perhaps because of competition for food against the other fish species. Early cartilaginous (Chondrichthyes) and bony fishes (Osteichthyes) also become diverse and played a large role within the Devonian seas. The first abundant genus of shark, Cladoselache, appeared in the oceans during the Devonian Period. The great diversity of fish around at the time has led to the Devonian being given the name "The Age of Fish" in popular culture. The first ammonites also appeared during or slightly before the early Devonian Period around 400 Mya. Reefs A now-dry barrier reef, located in present-day Kimberley Basin of northwest Australia, once extended , fringing a Devonian continent. Reefs in general are built by various carbonate-secreting organisms that have the ability to erect wave-resistant structures close to sea level. Although modern reefs are constructed mainly by corals and calcareous algae, Devonian reefs were either microbial reefs built up mostly by autotrophic cyanobacteria, or coral-stromatoporoid reefs built up by coral-like stromatoporoids and tabulate and rugose corals. Microbial reefs dominated under the warmer conditions of the early and late Devonian, while coral-stromatoporoid reefs dominated during the cooler middle Devonian. Terrestrial biota By the Devonian Period, life was well underway in its colonisation of the land. The moss forests and bacterial and algal mats of the Silurian were joined early in the period by primitive rooted plants that created the first stable soils and harbored arthropods like mites, scorpions, trigonotarbids and myriapods (although arthropods appeared on land much earlier than in the Early Devonian and the existence of fossils such as Protichnites suggest that amphibious arthropods may have appeared as early as the Cambrian). By far the largest land organism at the beginning of this period was the enigmatic Prototaxites, which was possibly the fruiting body of an enormous fungus, rolled liverwort mat, or another organism of uncertain affinities that stood more than tall, and towered over the low, carpet-like vegetation during the early part of the Devonian. Also the first possible fossils of insects appeared around 416 Mya, in the Early Devonian. Evidence for the earliest tetrapods takes the form of trace fossils in shallow lagoon environments within a marine carbonate platform / shelf during the Middle Devonian, although these traces have been questioned and an interpretation as fish feeding traces (Piscichnus) has been advanced. The greening of land Many Early Devonian plants did not have true roots or leaves like extant plants although vascular tissue is observed in many of those plants. Some of the early land plants such as Drepanophycus likely spread by vegetative growth and spores. The earliest land plants such as Cooksonia consisted of leafless, dichotomous axes and terminal sporangia and were generally very short-statured, and grew hardly more than a few centimetres tall. Fossils of Armoricaphyton chateaupannense, about 400 million years old, represent the oldest known plants with woody tissue. By the Middle Devonian, shrub-like forests of primitive plants existed: lycophytes, horsetails, ferns, and progymnosperms evolved. Most of these plants had true roots | of in the Early Devonian. levels dropped steeply throughout the Devonian Period. The newly evolved forests drew carbon out of the atmosphere, which were then buried into sediments. This may be reflected by a Mid-Devonian cooling of around . The Late Devonian warmed to levels equivalent to the Early Devonian; while there is no corresponding increase in concentrations, continental weathering increases (as predicted by warmer temperatures); further, a range of evidence, such as plant distribution, points to a Late Devonian warming. The climate would have affected the dominant organisms in reefs; microbes would have been the main reef-forming organisms in warm periods, with corals and stromatoporoid sponges taking the dominant role in cooler times. The warming at the end of the Devonian may even have contributed to the extinction of the stromatoporoids. Paleogeography The Devonian Period was a time of great tectonic activity, as Euramerica and Gondwana drew closer together. The continent Euramerica (or Laurussia) was created in the early Devonian by the collision of Laurentia and Baltica, which rotated into the natural dry zone along the Tropic of Capricorn, which is formed as much in Paleozoic times as nowadays by the convergence of two great air-masses, the Hadley cell and the Ferrel cell. In these near-deserts, the Old Red Sandstone sedimentary beds formed, made red by the oxidised iron (hematite) characteristic of drought conditions. Near the equator, the plate of Euramerica and Gondwana were starting to meet, beginning the early stages of the assembling of Pangaea. This activity further raised the northern Appalachian Mountains and formed the Caledonian Mountains in Great Britain and Scandinavia. The west coast of Devonian North America, by contrast, was a passive margin with deep silty embayments, river deltas and estuaries, found today in Idaho and Nevada; an approaching volcanic island arc reached the steep slope of the continental shelf in Late Devonian times and began to uplift deep water deposits, a collision that was the prelude to the mountain-building episode at the beginning of the Carboniferous called the Antler orogeny. Sea levels were high worldwide, and much of the land lay under shallow seas, where tropical reef organisms lived. The deep, enormous Panthalassa (the "universal ocean") covered the rest of the planet. Other minor oceans were the Paleo-Tethys Ocean, Proto-Tethys Ocean, Rheic Ocean, and Ural Ocean (which was closed during the collision with Siberia and Baltica). During the Devonian, Chaitenia, an island arc, accreted to Patagonia. Life Marine biota Sea levels in the Devonian were generally high. Marine faunas continued to be dominated by bryozoa, diverse and abundant brachiopods, the enigmatic hederellids, microconchids and corals. Lily-like crinoids (animals, their resemblance to flowers notwithstanding) were abundant, and trilobites were still fairly common. Among vertebrates, jawless armored fish (ostracoderms) declined in diversity, while the jawed fish (gnathostomes) simultaneously increased in both the sea and fresh water. Armored placoderms were numerous during the lower stages of the Devonian Period and became extinct in the Late Devonian, perhaps because of competition for food against the other fish species. Early cartilaginous (Chondrichthyes) and bony fishes (Osteichthyes) also become diverse and played a large role within the Devonian seas. The first abundant genus of shark, Cladoselache, appeared in the oceans during the Devonian Period. The great diversity of fish around at the time has led to the Devonian being given the name "The Age of Fish" in popular culture. The first ammonites also appeared during or slightly before the early Devonian Period around 400 Mya. Reefs A now-dry barrier reef, located in present-day Kimberley Basin of northwest Australia, once extended , fringing a Devonian continent. Reefs in general are built by various carbonate-secreting organisms that have the ability to erect wave-resistant structures close to sea level. Although modern reefs are constructed mainly by corals and calcareous algae, Devonian reefs were either microbial reefs built up mostly by autotrophic cyanobacteria, or coral-stromatoporoid reefs built up by coral-like stromatoporoids and tabulate and rugose corals. Microbial reefs dominated under the warmer conditions of the early and late Devonian, while coral-stromatoporoid reefs dominated during the cooler middle Devonian. Terrestrial biota By the Devonian Period, life was well underway in its colonisation of the land. The moss forests and bacterial and algal mats of the Silurian were joined early in the period by primitive rooted plants that created the first stable soils and harbored arthropods like mites, scorpions, trigonotarbids and myriapods (although arthropods appeared on land much earlier than in the Early Devonian and the existence of fossils such as Protichnites suggest that amphibious arthropods may have appeared as early as the Cambrian). By far the largest land organism at the beginning of this period was the enigmatic Prototaxites, which was possibly the fruiting body of an enormous fungus, rolled liverwort mat, or another organism of uncertain affinities that stood more than tall, and towered over the low, carpet-like vegetation during the early part of the Devonian. Also the first possible fossils of insects appeared around 416 Mya, in the Early Devonian. Evidence for the earliest tetrapods takes the form of trace fossils in shallow lagoon environments within a marine carbonate platform / shelf during the Middle Devonian, although these traces have been questioned and an interpretation as fish feeding traces (Piscichnus) has been advanced. The greening of land Many Early Devonian plants did not have true roots or leaves like extant plants although vascular tissue is observed in many of those plants. Some of the early land plants such as Drepanophycus likely spread by vegetative growth and spores. The earliest land plants such as Cooksonia consisted of leafless, dichotomous axes and terminal sporangia and were generally very short-statured, and grew hardly more than a few centimetres tall. Fossils of Armoricaphyton chateaupannense, about 400 million years old, represent the oldest known plants with woody tissue. By the Middle Devonian, shrub-like forests of primitive plants existed: lycophytes, horsetails, ferns, and progymnosperms evolved. Most of these plants had true roots and leaves, and many were quite tall. The earliest-known trees appeared in the Middle Devonian. These included a lineage of lycopods and another arborescent, woody vascular plant, the cladoxylopsids and progymnosperm Archaeopteris . These tracheophytes were able to grow to large size on dry land because they had evolved the ability to biosynthesize lignin, which gave them physical rigidity and improved the effectiveness of their vascular system |

expensive beaver pelts at that time even when a secretary's job would not pay terribly well), track supplies and other duties. On 23 December 1788, Thompson seriously fractured his tibia, forcing him to spend the next two winters at Cumberland House convalescing. It was during this time that he greatly refined and expanded his mathematical, astronomical, and surveying skills under the tutelage of Hudson's Bay Company surveyor Philip Turnor. It was also during this time that he lost sight in his right eye. In 1790, with his apprenticeship nearing its end, Thompson requested a set of surveying tools in place of the typical parting gift of fine clothes offered by the company to those completing their indenture. He received both. He entered the employ of the Hudson's Bay Company as a fur trader. In 1792 he completed his first significant survey, mapping a route to Lake Athabasca (where today's Alberta/Saskatchewan border is located). Between February and May 1793, Thompson made 34 observations of the longitude of Cumberland House using lunar distances. The mean of these observations was 102°12′ W, about 2' east of the modern value. The mean error of the 34 observations was about 15' of longitude. Broughton (2009) notes that the precision of the type of sextant used by Thompson was 15" of arc, corresponding to 7.5' of longitude giving an absolute limit to the precision of an individual observation. The error in Thompson's mean was several times less than this. The time he took on these observations, about 3 hours of calculation each, indicates that he understood the power of averages. In recognition of his map-making and surveying skills, the company promoted Thompson to the surveyor in 1794. He continued working for the Hudson's Bay Company until 23 May 1797 when, frustrated by an order to cease surveying and focus on the fur trade, he left. He walked in the snow in order to enter the employ of the competition, the North West Company. There he continued to work as a fur trader and surveyor. North West Company Thompson's decision to defect to the North West Company (NWC) in 1797 without providing the customary one-year notice was not well received by his former employers. But the North West Company was more supportive of Thompson pursuing his work on surveying and mapping the interior of what was to become Canada, as they judged it in the company's interest to know the exact locations of their settlements and the distance from each other. In 1797, Thompson was sent south by his employers to survey part of the Canada-US boundary along the water routes from Lake Superior to Lake of the Woods to satisfy unresolved questions of territory arising from the Jay Treaty between Great Britain and the United States after the American Revolutionary War. By 1798 Thompson had completed a survey of from Grand Portage, through Lake Winnipeg, to the headwaters of the Assiniboine and Mississippi rivers, as well as two sides of Lake Superior. In 1798, the company sent him to Red Deer Lake (Lac La Biche in present-day Alberta) to establish a trading post. (The English translation of Lac la Biche: Red Deer Lake, was first recorded on the Mackenzie map of 1793.) Thompson spent the next few seasons trading based in Fort George (now in Alberta), and during this time led several expeditions into the Rocky Mountains. On 10 July 1804, at the annual meeting of the North West Company in Kaministiquia, Thompson was made a full partner of the company. He became a 'wintering partner', who was based in the field rather than Montreal, with two of the 92 NWC's shares worth more than £4,000. He spent the next few seasons based there managing the fur trading operations but still finding time to expand his surveys of the waterways around Lake Superior. At the 1806 company meeting, officers decided to send Thompson back out into the interior. Concern over the American-backed expedition of Lewis and Clark prompted the North West Company to charge Thompson with the task of finding a route to the Pacific to open up the lucrative trading territories of the Pacific Northwest. Columbia River travels After the general meeting in 1806, Thompson travelled to Rocky Mountain House and prepared for an expedition to follow the Columbia River to the Pacific. In June 1807 Thompson crossed the Rocky Mountains and spent the summer surveying the Columbia basin; he continued to survey the area over the next few seasons. Thompson mapped and established trading posts in Northwestern Montana, Idaho, Washington, and Western Canada. Trading posts he founded included Kootenae House, Kullyspell House and Saleesh House; the latter two were the first trading posts west of the Rockies in Idaho and Montana, respectively. These posts established by Thompson extended North West Company fur trading territory into the Columbia Basin drainage area. The maps he made of the Columbia River basin east of the Cascade Mountains were of such high quality and detail that they continued to be useful into the 20th-century. In early 1810, Thompson was returning eastward toward Montreal but, while en route at Rainy Lake, received orders to return to the Rocky Mountains and establish a route to the mouth of the Columbia. The North West Company was responding to the plans of American John Jacob Astor to send a ship around the Americas to establish a fur trading post of the Pacific Fur Company on the Pacific Coast. During his return, Thompson was delayed by an angry group of Peigan natives at Howse Pass. He was | found one through the Athabasca Pass. David Thompson was the first European to navigate the full length of the Columbia River. Between Kettle Falls (3 July 1811) and the Junction of the Columbia and Snake Rivers (9 July) he was travelling through country that had never been visited by Europeans, and took time to visit the villages along the way to establish good relations, helped by copious quantities of tobacco. In 1805 Lewis and Clark had descended the Snake River, and then continued down the Columbia. On reaching the junction Thompson erected a pole and a notice claiming the country for Great Britain and stating the intention of the North West Company to build a trading post at the site. This notice was found later that year by Astor company workers looking to establish an inland fur post, contributing to their selection of a more northerly site at Fort Okanogan. The North West Company established its post of Fort Nez Percés near the Snake River confluence several years later. Continuing down the Columbia, Thompson passed over the Celilo Falls, almost losing the canoe on the rocks, and portaged around the rapids of The Dalles and the Cascades Rapids. On 14 July 1811, Thompson reached the partially constructed Fort Astoria at the mouth of the Columbia, arriving two months after the Pacific Fur Company's ship, the Tonquin. Before returning upriver and across the mountains, Thompson hired Naukane, a Native Hawaiian Takane labourer brought to Fort Astoria by the Pacific Fur Company's ship Tonquin. Naukane, known as Coxe to Thompson, accompanied Thompson across the continent to Lake Superior before journeying on to England. Thompson wintered at Saleesh House before beginning his final journey back to Montreal in 1812, where the North West Company was based. In his published journals, Thompson recorded seeing large footprints (“which measured fourteen inches in length by eight inches in breadth”) near what is now Jasper, Alberta, in 1811. It has been suggested that these prints were similar to what has since been called the sasquatch. However, Thompson noted that these tracks showed "a small Nail at the end of each [toe]", and stated that these tracks "very much resembles a large Bear's Track". The years 1807-1812 are the most carefully scrutinized in his career and his most enduring historical legacy, due to his development of the commercial routes across the Rockies, and his mapping of the lands they traverse. Appearance and personality In 1820, the English geologist, John Jeremiah Bigsby, attended a dinner party given by The Hon. William McGillivray at his home, Chateau St. Antoine, one of the early estates in Montreal's Golden Square Mile. He describes the party and some of the guests in his entertaining book The Shoe and Canoe, giving an excellent description of David Thompson: Marriage and children On 10 June 1799 at Île-à-la-Crosse, Thompson married Charlotte Small, a thirteen-year-old Métis daughter of Scottish fur trader Patrick Small and a Cree mother. Their marriage was formalised thirteen years later at the Scotch Presbyterian Church in Montreal on 30 October 1812. He and Charlotte had 13 children together; five of them were born before he left the fur trade. The family did not adjust easily to life in Eastern Canada; they lived in Montreal while he was traveling. Two of the children, John (aged 5) and Emma (aged 7), died of round worms, a common parasite. By the time of Thompson's death, the couple had been married 57 years, the longest marriage known in Canada pre-Confederation. Later life Upon his arrival back in Montreal, Thompson retired with a generous pension from the North West Company. He settled in nearby Terrebonne and worked on completing his great map, a summary of his lifetime of exploring and surveying the interior of North America. The map covered the wide area stretching from Lake Superior to the Pacific, and was given by Thompson to the North West Company. Thompson's 1814 map, his greatest achievement, was so accurate that 100 years later it was still the basis for many of the maps issued by the Canadian government. It now resides in the Archives of Ontario. In 1815, Thompson moved his family to Williamstown, Upper Canada, and a few years later was employed to survey the newly established borders with the United States from Lake of the Woods to the Eastern Townships of Quebec, established by Treaty of Ghent after the War of 1812. In 1843 Thompson completed his atlas of the region from Hudson Bay to the Pacific Ocean. Afterwards, Thompson returned to a life as a land owner, but soon financial misfortune would ruin him. By 1831 he was so deeply in debt he was forced to take up a position as a surveyor for the British American Land Company to provide for his family. His luck continued to worsen and he was forced to move in with his daughter and son-in-law in 1845. He began work on a manuscript chronicling his life exploring the continent, but this project was left unfinished when his sight failed him completely in 1851. Death and afterward The land mass mapped by Thompson amounted to of wilderness (one-fifth of the continent). His contemporary, the great explorer Alexander Mackenzie, remarked that Thompson did more in ten months than he would have thought possible in two years. Despite these significant achievements, Thompson died in Montreal in near obscurity on 10 February 1857, his accomplishments almost unrecognised. He never finished the book of his 28 years in the fur trade, based on his 77 field notebooks, before he died. In the 1890s geologist J.B. Tyrrell resurrected Thompson's notes and in 1916 published them as David Thompson's Narrative, as part of the General Series of the Champlain Society. Further editions and re-examinations of Thompson's life and works were published in 1962 by Richard Glover, in 1971 by Victor Hopwood, and in 2015 by William Moreau. Thompson's body was interred in Montreal's Mount Royal Cemetery in an unmarked grave. It was not until 1926 that efforts by J.B. Tyrrell and the Canadian Historical Society resulted in the placing of a tombstone to mark his grave. |
Dioscoreaceae and related families together. Hutchinson's circumscription of Dioscoreales included three other families in addition to Dioscoreaceae, Stenomeridaceae, Trichopodaceae and Roxburghiaceae. Of these only Trichopodaceae was included in the Angiosperm Phylogeny Group (APG) classification (see below), but was subsumed into Dioscoraceae. Stenomeridaceae, as Stenomeris was also included in Dioscoreaceae as subfamily Stenomeridoideae, the remaining genera being grouped in subfamily Dioscoreoideae. Roxburghiaceae on the other hand was segregated in the sister order Pandanales as Stemonaceae. Most taxonomists in the twentieth century (the exception was the 1981 Cronquist system which placed most such plants in order Liliales, subclass Liliidae, class Liliopsida=monocotyledons, division Magnoliophyta=angiosperms) recognised Dioscoreales as a distinct order, but demonstrated wide variations in its composition. Dahlgren, in the second version of his taxonomic classification (1982) raised the Liliiflorae to a superorder and placed Dioscoreales as an order within it. In his system, Dioscoreales contained only three families, Dioscoreaceae, Stemonaceae (i.e. Hutchinson's Roxburghiaceae) and Trilliaceae. The latter two families had been treated as a separate order (Stemonales, or Roxburghiales) by other authors, such as Huber (1969). The APG would later assign these to Pandanales and Liliales respectively. Dahlgren's construction of Dioscoreaceae included the Stenomeridaceae and Trichopodaceae, doubting these were distinct, and Croomiaceae in Stemonaceae. Furthermore, he expressed doubts about the order's homogeneity, especially Trilliaceae. The Dioscoreales at that time were marginally distinguishable from the Asparagales. In his examination of Huber's Stemonales, he found that the two constituent families had as close an affinity to Dioscoreaceae as to each other, and hence included them. He also considered closely related families and their relationship to Dioscoreales, such as the monogeneric Taccaceae, then in its own order, Taccales. Similar considerations were discussed with respect to two Asparagales families, Smilacaceae and Petermanniaceae. In Dahlgren's third and final version (1985) that broader circumscription of Dioscoreales was created within the superorder Lilianae, subclass Liliidae (monocotyledons), class Magnoliopsida (angiosperms) and comprised the seven families Dioscoreaceae, Petermanniaceae, Smilacaceae, Stemonaceae, Taccaceae, Trichopodaceae and Trilliaceae. Thismiaceae has either been treated as a separate family closely related to Burmanniaceae or as a tribe (Thismieae) within a more broadly defined Burmanniaceae, forming a separate order, Burmanniales, in the Dahlgren system. The related Nartheciaceae were treated as tribe Narthecieae within the Melanthiaceae in a third order, the Melanthiales, by Dahlgren. Dahlgren considered the Dioscoreales to most strongly resemble the ancestral monocotyledons, and hence sharing "dicotyledonous" characteristics, making it the most central monocotyledon order. Of these seven families, Bouman considered Dioscoreaceae, Trichopodaceae, Stemonaceae and Taccaceae to represent the "core" families of the order. However, that study also indicated both a clear delineation of the order from other orders particularly Asparagales, and a lack of homogeneity within the order. Molecular phylogenetics and the Angiosperm Phylogeny Group The increasing availability of molecular phylogenetics methods in addition to morphological characteristics in the 1990s led to major reconsiderations of the relationships within the monocotyledons. In that large multi-institutional examination of the seed plants using the plastid gene rbcL the authors used Dahlgren's system as their basis, but followed Thorne (1992) in altering the suffixes of the superorders from "-iflorae" to "-anae". This demonstrated that the Lilianae comprised three lineages corresponding to Dahlgren's orders Dioscoreales, Liliales, and Asparagaless. Under the Angiosperm Phylogeny Group system of 1998, which took Dahlgren's system as a basis, the order was placed in the monocot clade and comprised the five families Burmanniaceae, Dioscoreaceae, Taccaceae, Thismiaceae and Trichopodaceae. In APG II (2003), a number of changes were made to Dioscoreales, as a result of an extensive study by Caddick and | other authors, such as Huber (1969). The APG would later assign these to Pandanales and Liliales respectively. Dahlgren's construction of Dioscoreaceae included the Stenomeridaceae and Trichopodaceae, doubting these were distinct, and Croomiaceae in Stemonaceae. Furthermore, he expressed doubts about the order's homogeneity, especially Trilliaceae. The Dioscoreales at that time were marginally distinguishable from the Asparagales. In his examination of Huber's Stemonales, he found that the two constituent families had as close an affinity to Dioscoreaceae as to each other, and hence included them.

Thismiaceae has either been treated as a separate family closely related to Burmanniaceae or as a tribe (Thismieae) within a more broadly defined Burmanniaceae, forming a separate order, Burmanniales, in the Dahlgren system. The related Nartheciaceae were treated as tribe Narthecieae within the Melanthiaceae in a third order, the Melanthiales, by Dahlgren.

Under the Angiosperm Phylogeny Group system of 1998, which took Dahlgren's system as a basis, the order was placed in the monocot clade and comprised the five families Burmanniaceae, Dioscoreaceae, Taccaceae, Thismiaceae and Trichopodaceae. In APG II (2003), a number of changes were made to Dioscoreales, as a result of an extensive study by Caddick and colleagues (2002), using an analysis of three genes, rbcL, atpB and 18S rDNA, in addition to morphology. These studies resulted in a re-examination of the relationships between most of the genera within the order. Thismiaceae was shown to be a sister group to Burmanniaceae, and so was included in it. The monotypic families Taccaceae and Trichopodaceae were included in Dioscoreaceae, while Nartheciaceae could also be grouped within Dioscoreales. APG III (2009) did not change this, so the order now comprises three families Burmanniaceae, Dioscoreaceae and Nartheciaceae. Although further research on the deeper relationships within Dioscoreales continues, the APG IV (2016) authors felt it was still premature to propose a restructuring of the order.

evidence-based research and evidence-based practice. Dental treatments are carried out by a dental team, which often consists of a dentist and dental auxiliaries (dental assistants, dental hygienists, dental technicians, as well as dental therapists). Most dentists either work in private practices (primary care), dental hospitals or (secondary care) institutions (prisons, armed forces bases, etc.). The history of dentistry is almost as ancient as the history of humanity and civilization with the earliest evidence dating from 7000 BC to 5500 BC. Skeletal remains from Mehgarh (now in Pakistan) dated to that time show evidence of teeth having been drilled with flint tools to remove decay, a method found to be "surprisingly effective". Dentistry is thought to have been the first specialization in medicine which have gone on to develop its own accredited degree with its own specialisations. The modern movement of evidence-based dentistry calls for the use of high-quality scientific research and evidence to guide decision-making such as in manual tooth conservation, use of fluoride water treatment and fluoride toothpaste, dealing with oral diseases such as tooth decay and periodontitis, as well as systematic diseases such as osteoporosis, diabetes, celiac disease, cancer, HIV/AIDS which could also affect the oral cavity. Other practices relevant to evidence-based dentistry include radiology of the mouth to inspect teeth deformity or oral malaises, haematology (study of blood) to avoid bleeding complications during dental surgery, cardiology (due to various severe complications arising from dental surgery with patients with heart disease), etc. Terminology The term dentistry comes from dentist, which comes from French dentiste, which comes from the French and Latin words for tooth. The term for the associated scientific study of teeth is odontology (from ) – the study of the structure, development, and abnormalities of the teeth. Dental treatment Dentistry usually encompasses practices related to the oral cavity. According to the World Health Organization, oral diseases are major public health problems due to their high incidence and prevalence across the globe, with the disadvantaged affected more than other socio-economic groups. The majority of dental treatments are carried out to prevent or treat the two most common oral diseases which are dental caries (tooth decay) and periodontal disease (gum disease or pyorrhea). Common treatments involve the restoration of teeth, extraction or surgical removal of teeth, scaling and root planing, endodontic root canal treatment, and cosmetic dentistry All dentists in the United States undergo at least three years of undergraduate studies, but nearly all complete a bachelor's degree. This schooling is followed by four years of dental school to qualify as a "Doctor of Dental Surgery" (DDS) or "Doctor of Dental Medicine" (DMD). Specialization in dentistry is available in the fields of Anesthesiology, Dental Public Health, Endodontics, Oral Radiology, Oral Maxillofacial Surgery, Oral Medicine, Orofacial Pain, Pathology, Orthodontics, Pediatric Dentistry, Periodontics, and Prosthodontics. By nature of their general training they can carry out the majority of dental treatments such as restorative (fillings, crowns, bridges), prosthetic (dentures), endodontic (root canal) therapy, periodontal (gum) therapy, and extraction of teeth, as well as performing examinations, radiographs (x-rays), and diagnosis. Dentists can also prescribe medications such as antibiotics, sedatives, and any other drugs used in patient management. Depending on their licensing boards, general dentists may be required to complete additional training to perform sedation, dental implants, etc. Dentists also encourage prevention of oral diseases through proper hygiene and regular, twice or more yearly, checkups for professional cleaning and evaluation. Oral infections and inflammations may affect overall health and conditions in the oral cavity may be indicative of systemic diseases, such as osteoporosis, diabetes, celiac disease or cancer. Many studies have also shown that gum disease is associated with an increased risk of diabetes, heart disease, and preterm birth. The concept that oral health can affect systemic health and disease is referred to as "oral-systemic health". Education and licensing John M. Harris started the world's first dental school in Bainbridge, Ohio, and helped to establish dentistry as a health profession. It opened on 21 February 1828, and today is a dental museum. The first dental college, Baltimore College of Dental Surgery, opened in Baltimore, Maryland, US in 1840. The second in the United States was the Ohio College of Dental Surgery, established in Cincinnati, Ohio, in 1845. The Philadelphia College of Dental Surgery followed in 1852. In 1907, Temple University accepted a bid to incorporate the school. Studies show that dentists that graduated from different countries, or even from different dental schools in one country, may make different clinical decisions for the same clinical condition. For example, dentists that graduated from Israeli dental schools may recommend the removal of asymptomatic impacted third molar (wisdom teeth) more often than dentists that graduated from Latin American or Eastern European dental schools. In the United Kingdom, the first dental schools, the London School of Dental Surgery and the Metropolitan School of Dental Science, both in London, opened in 1859. The 1878 British Dentists Act of 1878 and the 1879 Dentists Register limited the title of "dentist" and "dental surgeon" to qualified and registered practitioners. However, others could legally describe themselves as "dental experts" or "dental consultants". The practice of dentistry in the United Kingdom became fully regulated with the 1921 Dentists Act, which required the registration of anyone practising dentistry. The British Dental Association, formed in 1880 with Sir John Tomes as president, played a major role in prosecuting dentists practising illegally. Dentists in the United Kingdom are now regulated by the General Dental Council. In Korea, Taiwan, Japan, Finland, Sweden, Brazil, Chile, the United States, and Canada, a dentist is a healthcare professional qualified to practice dentistry after graduating with a degree of either Doctor of Dental Surgery (DDS) or Doctor of Dental Medicine (DMD). This is equivalent to the Bachelor of Dental Surgery/Baccalaureus Dentalis Chirurgiae (BDS, BDent, BChD, BDSc) that is awarded in the UK and British Commonwealth countries. In most western countries, to become a qualified dentist one must usually complete at least four years of postgraduate study; within the European Union the education has to be at least five years. Dentists usually complete between five and eight years of post-secondary education before practising. Though not mandatory, many dentists choose to complete an internship or residency focusing on specific aspects of dental care after they have received their dental degree. Specialties Some dentists undertake further training after their initial degree in order to specialize. Exactly which subjects are recognized by dental registration bodies varies according to location. Examples include: Cosmetic dentistry- Focuses on improving the appearance of the mouth, teeth and smile. Anesthesiology – The specialty of dentistry that deals with the advanced use of general anesthesia, sedation and pain management to facilitate dental procedures. Dental public health – The study of epidemiology and social health policies relevant to oral health. Endodontics (also called endodontology) – Root canal therapy and study of diseases of the dental pulp and periapical tissues. Forensic odontology – The gathering and use of dental evidence in law. This may be performed by any dentist with experience or training in this field. The function of the forensic dentist is primarily documentation and verification of identity. Geriatric dentistry or geriodontics – The delivery of dental care to older adults involving the diagnosis, prevention, and treatment of problems associated with normal aging and age-related diseases as part of an interdisciplinary team with other health care professionals. Oral and maxillofacial pathology – The study, diagnosis, and sometimes the treatment of oral and maxillofacial related diseases. Oral and maxillofacial radiology – The study and radiologic interpretation of oral and maxillofacial diseases. Oral and maxillofacial surgery (also called oral surgery) – Extractions, implants, and surgery of the jaws, mouth and face. Oral biology – Research in dental and craniofacial biology Oral Implantology – The art and science of replacing extracted teeth with dental implants. Oral medicine – The clinical evaluation and diagnosis of oral mucosal diseases Orthodontics and dentofacial orthopedics – The straightening of teeth and modification of midface and mandibular growth. Pediatric dentistry (also called pedodontics) – Dentistry for children Periodontology (also called periodontics) – The study and treatment of diseases of the periodontium (non-surgical and surgical) as well as placement and maintenance of dental implants Prosthodontics (also called prosthetic dentistry) – Dentures, bridges and the restoration of implants. Some prosthodontists super-specialize in maxillofacial prosthetics, which is the discipline originally concerned with the rehabilitation of patients with congenital facial and oral defects such as cleft lip and palate or patients born with an underdeveloped ear (microtia). Today, most maxillofacial prosthodontists return function and esthetics to patients with acquired defects secondary to surgical removal of head and neck tumors, or secondary to trauma from war or motor vehicle accidents. Special needs dentistry (also called special care dentistry) – Dentistry for those with developmental and acquired disabilities. Sports dentistry – the branch of sports medicine dealing with prevention and treatment of dental injuries and oral diseases associated with sports and exercise. The sports dentist works as | Specialization in dentistry is available in the fields of Anesthesiology, Dental Public Health, Endodontics, Oral Radiology, Oral Maxillofacial Surgery, Oral Medicine, Orofacial Pain, Pathology, Orthodontics, Pediatric Dentistry, Periodontics, and Prosthodontics. By nature of their general training they can carry out the majority of dental treatments such as restorative (fillings, crowns, bridges), prosthetic (dentures), endodontic (root canal) therapy, periodontal (gum) therapy, and extraction of teeth, as well as performing examinations, radiographs (x-rays), and diagnosis. Dentists can also prescribe medications such as antibiotics, sedatives, and any other drugs used in patient management. Depending on their licensing boards, general dentists may be required to complete additional training to perform sedation, dental implants, etc. Dentists also encourage prevention of oral diseases through proper hygiene and regular, twice or more yearly, checkups for professional cleaning and evaluation. Oral infections and inflammations may affect overall health and conditions in the oral cavity may be indicative of systemic diseases, such as osteoporosis, diabetes, celiac disease or cancer. Many studies have also shown that gum disease is associated with an increased risk of diabetes, heart disease, and preterm birth. The concept that oral health can affect systemic health and disease is referred to as "oral-systemic health". Education and licensing John M. Harris started the world's first dental school in Bainbridge, Ohio, and helped to establish dentistry as a health profession. It opened on 21 February 1828, and today is a dental museum. The first dental college, Baltimore College of Dental Surgery, opened in Baltimore, Maryland, US in 1840. The second in the United States was the Ohio College of Dental Surgery, established in Cincinnati, Ohio, in 1845. The Philadelphia College of Dental Surgery followed in 1852. In 1907, Temple University accepted a bid to incorporate the school. Studies show that dentists that graduated from different countries, or even from different dental schools in one country, may make different clinical decisions for the same clinical condition. For example, dentists that graduated from Israeli dental schools may recommend the removal of asymptomatic impacted third molar (wisdom teeth) more often than dentists that graduated from Latin American or Eastern European dental schools. In the United Kingdom, the first dental schools, the London School of Dental Surgery and the Metropolitan School of Dental Science, both in London, opened in 1859. The 1878 British Dentists Act of 1878 and the 1879 Dentists Register limited the title of "dentist" and "dental surgeon" to qualified and registered practitioners. However, others could legally describe themselves as "dental experts" or "dental consultants". The practice of dentistry in the United Kingdom became fully regulated with the 1921 Dentists Act, which required the registration of anyone practising dentistry. The British Dental Association, formed in 1880 with Sir John Tomes as president, played a major role in prosecuting dentists practising illegally.

circle. Both definitions are also valid for the diameter of a sphere. In more modern usage, the length of a diameter is also called the diameter. In this sense one speaks of diameter rather than diameter (which refers to the line segment itself), because all diameters of a circle or sphere have the same length, this being twice the radius For a convex shape in the plane, the diameter is defined to be the largest distance that can be formed between two opposite parallel lines tangent to its boundary, and the is often defined to be the smallest such distance. Both quantities can be calculated efficiently using rotating calipers. For a curve of constant width such as the Reuleaux triangle, the width and diameter are the same because all such pairs of parallel tangent lines have the same distance. For an ellipse, the standard terminology is different. A diameter of an ellipse is any chord passing through the centre of the ellipse. For example, conjugate diameters have the property that a tangent line to the ellipse at the endpoint of one diameter is parallel to the conjugate diameter.

toxicity of ethanol, the main psychoactive component of alcoholic beverages, other physiological symptoms may arise from the activity of acetaldehyde, a metabolite of alcohol. These effects may not arise until hours after ingestion and may contribute to the condition colloquially known as a hangover. Symptoms of intoxication at lower doses may include mild sedation and poor coordination. At higher doses, there may be slurred speech, trouble walking, and vomiting. Extreme doses may result in a respiratory depression, coma, or death. Complications may include seizures, aspiration pneumonia, injuries including suicide, and low blood sugar. Alcohol intoxication can lead to alcohol-related crime with perpetrators more likely to be intoxicated than victims. Alcohol intoxication typically begins after two or more alcoholic drinks. Risk factors include a social situation where heavy drinking is common and a person having an impulsive personality. Diagnosis is usually based on the history of events and physical examination. Verification of events by witnesses may be useful. Legally, alcohol intoxication is often defined as a blood alcohol concentration (BAC) of greater than 5.4–17.4 mmol/L (25–80 mg/dL or 0.025–0.080%). This can be measured by blood or breath testing. Alcohol is broken down in the human body at a rate of about 3.3 mmol/L (15 mg/dL) per hour, depending on an individual's metabolic rate (metabolism). Management of alcohol intoxication involves supportive care. Typically this includes putting the person in the recovery position, keeping the person warm, and making sure breathing is sufficient. Gastric lavage and activated charcoal have not been found to be useful. Repeated assessments may be required to rule out other potential causes of a person's symptoms. Acute intoxication has been documented throughout history, and alcohol remains one of the world's most widespread recreational drugs. Some religions consider alcohol intoxication to be a sin. Symptoms Alcohol intoxication leads to negative health effects due to the recent drinking of ethanol (alcohol). When severe it may become a medical emergency. Some effects of alcohol intoxication, such as euphoria and lowered social inhibition, are central to alcohol's desirability. Pathophysiology Alcohol is metabolized by a normal liver at the rate of about 8 grams of pure ethanol per hour. 8 grams or is one British standard unit. An "abnormal" liver with conditions such as hepatitis, cirrhosis, gall bladder disease, and cancer is likely to result in a slower rate of metabolism. Ethanol is metabolised to acetaldehyde by alcohol dehydrogenase (ADH), which is found in many tissues, including the gastric mucosa. Acetaldehyde is metabolised to acetate by acetaldehyde dehydrogenase (ALDH), which is found predominantly in liver mitochondria. Acetate is used by the muscle cells to produce acetyl-CoA using the enzyme acetyl-CoA synthetase, and the acetyl-CoA is then used in the citric acid cycle. As drinking increases, people become sleepy, or fall into a stupor. After a very high level of consumption, the respiratory system becomes depressed and the person will stop breathing. Comatose patients may aspirate their vomit (resulting in vomitus in the lungs, which may cause "drowning" and later pneumonia if survived). CNS depression and impaired motor co-ordination along with poor judgment increases the likelihood of accidental injury occurring. It is estimated that about one-third of alcohol-related deaths are due to accidents and another 14% are from intentional injury. In addition to respiratory failure and accidents caused by effects on the central nervous system, alcohol causes significant metabolic derangements. Hypoglycaemia occurs due to ethanol's inhibition of gluconeogenesis, especially in children, and may cause lactic acidosis, ketoacidosis, and acute kidney injury. Metabolic acidosis is compounded by respiratory failure. Patients may also present with hypothermia. Mechanism In the past, alcohol was believed to be a non-specific pharmacological agent affecting many neurotransmitter systems in the brain. However, molecular pharmacology studies have shown that alcohol has only a few primary targets. In some systems, these effects are facilitatory and in others inhibitory. Among the neurotransmitter systems with enhanced functions are: GABAA, 5-HT3 receptor agonism (responsible for GABAergic (GABAA receptor PAM), glycinergic, and cholinergic effects), nicotinic acetylcholine receptors. Among those that are inhibited are: NMDA, dihydropyridine-sensitive L-type Ca2+ channels and G-protein-activated inwardly rectifying K+ channels. Alcohol is also converted to a lipid metabolite phosphatidylethanol by phospholipase D2 and this metabolite is shown to bind directly to and regulate ion channels. The result of these direct effects is a wave of further indirect effects involving a variety of other neurotransmitter and neuropeptide systems, leading finally to the behavioural or symptomatic effects of alcohol intoxication. The order in which different types of alcohol are consumed ("Grape or grain but never the twain" and "Beer before wine and you'll feel fine; wine before beer and you'll feel queer") does not have any effect. GABAA receptors Many of the effects of activating GABAA receptors have the same effects as that of ethanol consumption. Some of these effects include anxiolytic, anticonvulsant, sedative, and hypnotic effects, cognitive impairment, and motor incoordination. This correlation between activating GABAA receptors and the effects of ethanol consumption has led to the study of ethanol and its effects on GABAA receptors. It has been shown that ethanol does in fact exhibit positive allosteric binding properties to GABAA receptors. However, its effects are limited to pentamers containing the δ-subunit rather than the γ-subunit. GABAA receptors containing the δ-subunit have been shown to be located exterior to the synapse and are involved with tonic inhibition rather than its γ-subunit counterpart, which is involved in phasic inhibition. The δ-subunit has been shown to be able to form the allosteric binding site which makes GABAA receptors containing the δ-subunit more sensitive to ethanol concentrations, even to moderate social ethanol consumption levels (30mM). While it has been shown by Santhakumar et al. that GABAA receptors containing the δ-subunit are sensitive to ethanol modulation, depending on subunit combinations receptors could be more or less sensitive to ethanol. It has been shown that GABAA receptors that contain both δ and β3-subunits display increased sensitivity to ethanol. One such receptor that exhibits ethanol insensitivity is α3-β6-δ GABAA. It has also been shown that subunit combination is not the only thing that contributes to ethanol sensitivity. Location of GABAA receptors within the synapse may also contribute to ethanol sensitivity. Diagnosis Alcohol intoxication is described as a mental and behavioural disorder by the International Classification of Diseases. (ICD-10). Definitive diagnosis relies on a blood test for alcohol, usually performed as part of a toxicology screen. Law enforcement officers in the United States and other countries often use breathalyzer units and field sobriety tests as more convenient and rapid alternatives to blood tests. There are also various models of breathalyzer units that are available for consumer use. Because these may have varying reliability and may produce different results than the tests used for law-enforcement purposes, the results from such devices should be conservatively interpreted. Many informal intoxication tests exist, which, in general, are unreliable and not recommended as deterrents to excessive intoxication or as indicators of the safety of activities such as motor vehicle driving, heavy equipment operation, machine tool use, etc. For determining whether someone is intoxicated by alcohol by some means other than a blood-alcohol test, it is necessary to rule out other conditions such as hypoglycemia, stroke, usage of other intoxicants, mental health issues, and so on. It is best if their behavior has been observed while the subject is sober to establish a baseline. Several well-known criteria can be used to establish a probable diagnosis. For a physician in the acute-treatment setting, acute alcohol intoxication can mimic other acute neurological disorders, or is frequently combined with other recreational drugs that complicate diagnosis and treatment. Management Acute alcohol poisoning is a medical emergency due to the risk of death from respiratory depression or aspiration of vomit if vomiting occurs while the person is unresponsive. Emergency treatment strives to stabilize and maintain an open airway and sufficient breathing, while waiting for the alcohol to metabolize. This can be done by removal of any vomit or, if the person is unconscious or has impaired gag reflex, intubation of the trachea. Other measures may include Treat low blood sugar, with intravenous sugar solutions as ethanol induced low blood sugar unresponsive to glucagon. Administer the vitamin thiamine to prevent Wernicke–Korsakoff syndrome, which can cause a seizure (more usually a treatment for chronic alcoholism, but in the acute context usually co-administered to ensure maximal benefit). Hemodialysis if the blood concentration is very high at >130 mmol/l (>600 mg/dL) Provide oxygen therapy as needed via nasal cannula or non-rebreather mask. While the medication metadoxine may speed the breakdown of alcohol, use in alcohol intoxication requires further study as of 2017. It is approved in a number of countries in Europe, as well as India and Brazil. Additional medication may be indicated for treatment of nausea, tremor, and anxiety. Clinical findings Hospital admissions Alcohol intoxication was found to be prevalent in clinical populations within the United States involving people treated for trauma and in the age group of people aged within their 18th - 24th years (in a study of a group for the years 1999 - 2004). In the United States during the years 2010 - 2012, acute intoxication was found to be the direct cause of an average of 2,221 deaths, in the sample group of those aged within their 15th year or older.

Prognosis A normal liver detoxifies the blood of alcohol over a period of time that depends on the initial level and the patient's overall physical condition. An abnormal liver will take longer but still succeeds, provided the alcohol does not cause liver failure. People having drunk heavily for several days or weeks may have withdrawal symptoms after the acute intoxication has subsided. A person consuming a dangerous amount of alcohol persistently can develop memory blackouts and idiosyncratic intoxication or pathological drunkenness symptoms. Long-term persistent consumption of excessive amounts of alcohol can cause liver damage and have other deleterious health effects. Society and culture Alcohol intoxication is a risk factor in some cases of catastrophic injury, in particular for unsupervised recreational activity. A study in the province of Ontario based on epidemiological data from 1986, 1989, 1992, and 1995 states that 79.2% of the 2,154 catastrophic injuries recorded for the study were preventable, of which 346 (17%) involved alcohol consumption. The activities most commonly associated with alcohol-related catastrophic injury were snowmobiling (124), fishing (41), diving (40), boating (31) and canoeing (7), swimming (31), riding an all-terrain vehicle (24), and cycling (23). These events are often associated with unsupervised young males, often inexperienced in the activity, and many result in drowning. Alcohol use is also associated with unsafe sex. Legal issues Laws on drunkenness vary. In the United States, it is a criminal offense for a person to be drunk while driving a motorized vehicle, except in Wisconsin, where it is only a fine for the first offense. It is also a criminal offense to fly an aircraft or (in some American states) to assemble or operate an amusement park ride while drunk. Similar laws also exist in the United Kingdom and most other countries. In some countries, it is also an offense to serve alcohol to an already-intoxicated person, and, often, alcohol can be sold only by persons qualified to serve responsibly through alcohol server training. The blood alcohol content (BAC) for legal operation of a vehicle is typically measured as a percentage of a unit volume of blood. This percentage ranges from 0.00% in Romania and the United Arab Emirates; to 0.05% in Australia, South Africa, Germany, Scotland and New Zealand (0.00% for underage individuals); to 0.08% in England and Wales, the United States and Canada. The United States Federal Aviation Administration prohibits crew members from performing their duties within eight hours of consuming an alcoholic beverage, while under the influence of alcohol, or with a BAC greater than 0.04%. In the United States, the United Kingdom, and Australia, public intoxication is a crime (also known as "being drunk and disorderly" or "being drunk and incapable"). In some countries, there are special facilities, sometimes known as "drunk tanks", for the temporary detention of persons found to be drunk. Religious views Christianity Some religious groups permit the consumption of alcohol; some permit consumption but prohibit intoxication; others prohibit any amount of alcohol consumption altogether. Many denominations of Christianity, such as Catholicism, Orthodoxy and Lutheranism, use wine as a part of the Eucharist and permit its consumption, but consider it sinful to become intoxicated.

SLS (Scalable to Lossless), WavPack, and OptimFROG DualStream. When audio files are to be processed, either by further compression or for editing, it is desirable to work from an unchanged original (uncompressed or losslessly compressed). Processing of a lossily compressed file for some purpose usually produces a final result inferior to the creation of the same compressed file from an uncompressed original. In addition to sound editing or mixing, lossless audio compression is often used for archival storage, or as master copies. Lossy audio compression Lossy audio compression is used in a wide range of applications. In addition to standalone audio-only applications of file playback in MP3 players or computers, digitally compressed audio streams are used in most video DVDs, digital television, streaming media on the Internet, satellite and cable radio, and increasingly in terrestrial radio broadcasts. Lossy compression typically achieves far greater compression than lossless compression, by discarding less-critical data based on psychoacoustic optimizations. Psychoacoustics recognizes that not all data in an audio stream can be perceived by the human auditory system. Most lossy compression reduces redundancy by first identifying perceptually irrelevant sounds, that is, sounds that are very hard to hear. Typical examples include high frequencies or sounds that occur at the same time as louder sounds. Those irrelevant sounds are coded with decreased accuracy or not at all. Due to the nature of lossy algorithms, audio quality suffers a digital generation loss when a file is decompressed and recompressed. This makes lossy compression unsuitable for storing the intermediate results in professional audio engineering applications, such as sound editing and multitrack recording. However, lossy formats such as MP3 are very popular with end-users as the file size is reduced to 5-20% of the original size and a megabyte can store about a minute's worth of music at adequate quality. Coding methods To determine what information in an audio signal is perceptually irrelevant, most lossy compression algorithms use transforms such as the modified discrete cosine transform (MDCT) to convert time domain sampled waveforms into a transform domain, typically the frequency domain. Once transformed, component frequencies can be prioritized according to how audible they are. Audibility of spectral components is assessed using the absolute threshold of hearing and the principles of simultaneous masking—the phenomenon wherein a signal is masked by another signal separated by frequency—and, in some cases, temporal masking—where a signal is masked by another signal separated by time. Equal-loudness contours may also be used to weigh the perceptual importance of components. Models of the human ear-brain combination incorporating such effects are often called psychoacoustic models. Other types of lossy compressors, such as the linear predictive coding (LPC) used with speech, are source-based coders. LPC uses a model of the human vocal tract to analyze speech sounds and infer the parameters used by the model to produce them moment to moment. These changing parameters are transmitted or stored and used to drive another model in the decoder which reproduces the sound. Lossy formats are often used for the distribution of streaming audio or interactive communication (such as in cell phone networks). In such applications, the data must be decompressed as the data flows, rather than after the entire data stream has been transmitted. Not all audio codecs can be used for streaming applications. Latency is introduced by the methods used to encode and decode the data. Some codecs will analyze a longer segment, called a frame, of the data to optimize efficiency, and then code it in a manner that requires a larger segment of data at one time to decode. The inherent latency of the coding algorithm can be critical; for example, when there is a two-way transmission of data, such as with a telephone conversation, significant delays may seriously degrade the perceived quality. In contrast to the speed of compression, which is proportional to the number of operations required by the algorithm, here latency refers to the number of samples that must be analyzed before a block of audio is processed. In the minimum case, latency is zero samples (e.g., if the coder/decoder simply reduces the number of bits used to quantize the signal). Time domain algorithms such as LPC also often have low latencies, hence their popularity in speech coding for telephony. In algorithms such as MP3, however, a large number of samples have to be analyzed to implement a psychoacoustic model in the frequency domain, and latency is on the order of 23 ms. Speech encoding Speech encoding is an important category of audio data compression. The perceptual models used to estimate what aspects of speech a human ear can hear are generally somewhat different from those used for music. The range of frequencies needed to convey the sounds of a human voice is normally far narrower than that needed for music, and the sound is normally less complex. As a result, speech can be encoded at high quality using a relatively low bit rate. This is accomplished, in general, by some combination of two approaches: Only encoding sounds that could be made by a single human voice. Throwing away more of the data in the signal—keeping just enough to reconstruct an "intelligible" voice rather than the full frequency range of human hearing. The earliest algorithms used in speech encoding (and audio data compression in general) were the A-law algorithm and the μ-law algorithm. History Early audio research was conducted at Bell Labs. There, in 1950, C. Chapin Cutler filed the patent on differential pulse-code modulation (DPCM). In 1973, Adaptive DPCM (ADPCM) was introduced by P. Cummiskey, Nikil S. Jayant and James L. Flanagan. Perceptual coding was first used for speech coding compression, with linear predictive coding (LPC). Initial concepts for LPC date back to the work of Fumitada Itakura (Nagoya University) and Shuzo Saito (Nippon Telegraph and Telephone) in 1966. During the 1970s, Bishnu S. Atal and Manfred R. Schroeder at Bell Labs developed a form of LPC called adaptive predictive coding (APC), a perceptual coding algorithm that exploited the masking properties of the human ear, followed in the early 1980s with the code-excited linear prediction (CELP) algorithm which achieved a significant compression ratio for its time. Perceptual coding is used by modern audio compression formats such as MP3 and AAC. Discrete cosine transform (DCT), developed by Nasir Ahmed, T. Natarajan and K. R. Rao in 1974, provided the basis for the modified discrete cosine transform (MDCT) used by modern audio compression formats such as MP3, Dolby Digital, and AAC. MDCT was proposed by J. P. Princen, A. W. Johnson and A. B. Bradley in 1987, following earlier work by Princen and Bradley in 1986. The world's first commercial broadcast automation audio compression system was developed by Oscar Bonello, an engineering professor at the University of Buenos Aires. In 1983, using the psychoacoustic principle of the masking of critical bands first published in 1967, he started developing a practical application based on the recently developed IBM PC computer, and the broadcast automation system was launched in 1987 under the name Audicom. Twenty years later, almost all the radio stations in the world were using similar technology manufactured by a number of companies. A literature compendium for a large variety of audio coding systems was published in the IEEE's Journal on Selected Areas in Communications (JSAC), in February 1988. While there were some papers from before that time, this collection documented an entire variety of finished, working audio coders, nearly all of them using perceptual techniques and some kind of frequency analysis and back-end noiseless coding. Video Uncompressed video requires a very high data rate. Although lossless video compression codecs perform at a compression factor of 5 to 12, a typical H.264 lossy compression video has a compression factor between 20 and 200. The two key video compression techniques used in video coding standards are the discrete cosine transform (DCT) and motion compensation (MC). Most video coding standards, such as the H.26x and MPEG formats, typically use motion-compensated DCT video coding (block motion compensation). Most video codecs are used alongside audio compression techniques to store the separate but complementary data streams as one combined package using so-called container formats. Encoding theory Video data may be represented as a series of still image frames. Such data usually contains abundant amounts of spatial and temporal redundancy. Video compression algorithms attempt to reduce redundancy and store information more compactly. Most video compression formats and codecs exploit both spatial and temporal redundancy (e.g. through difference coding with motion compensation). Similarities can be encoded by only storing differences between e.g. temporally adjacent frames (inter-frame coding) or | frequency—and, in some cases, temporal masking—where a signal is masked by another signal separated by time. Equal-loudness contours may also be used to weigh the perceptual importance of components. Models of the human ear-brain combination incorporating such effects are often called psychoacoustic models. Other types of lossy compressors, such as the linear predictive coding (LPC) used with speech, are source-based coders. LPC uses a model of the human vocal tract to analyze speech sounds and infer the parameters used by the model to produce them moment to moment. These changing parameters are transmitted or stored and used to drive another model in the decoder which reproduces the sound. Lossy formats are often used for the distribution of streaming audio or interactive communication (such as in cell phone networks). In such applications, the data must be decompressed as the data flows, rather than after the entire data stream has been transmitted. Not all audio codecs can be used for streaming applications. Latency is introduced by the methods used to encode and decode the data. Some codecs will analyze a longer segment, called a frame, of the data to optimize efficiency, and then code it in a manner that requires a larger segment of data at one time to decode. The inherent latency of the coding algorithm can be critical; for example, when there is a two-way transmission of data, such as with a telephone conversation, significant delays may seriously degrade the perceived quality. In contrast to the speed of compression, which is proportional to the number of operations required by the algorithm, here latency refers to the number of samples that must be analyzed before a block of audio is processed. In the minimum case, latency is zero samples (e.g., if the coder/decoder simply reduces the number of bits used to quantize the signal). Time domain algorithms such as LPC also often have low latencies, hence their popularity in speech coding for telephony. In algorithms such as MP3, however, a large number of samples have to be analyzed to implement a psychoacoustic model in the frequency domain, and latency is on the order of 23 ms.

Video compression algorithms attempt to reduce redundancy and store information more compactly. Most video compression formats and codecs exploit both spatial and temporal redundancy (e.g. through difference coding with motion compensation). Similarities can be encoded by only storing differences between e.g. temporally adjacent frames (inter-frame coding) or spatially adjacent pixels (intra-frame coding). Inter-frame compression (a temporal delta encoding) (re)uses data from one or more earlier or later frames in a sequence to describe the current frame. Intra-frame coding, on the other hand, uses only data from within the current frame, effectively being still-image compression. The intra-frame video coding formats used in camcorders and video editing employ simpler compression that uses only intra-frame prediction. This simplifies video editing software, as it prevents a situation in which a compressed frame refers to data that the editor has deleted. Usually, video compression additionally employs lossy compression techniques like quantization that reduce aspects of the source data that are (more or less) irrelevant to the human visual perception by exploiting perceptual features of human vision. For example, small differences in color are more difficult to perceive than are changes in brightness. Compression algorithms can average a color across these similar areas in a manner similar to those used in JPEG image compression. As in all lossy compression, there is a trade-off between video quality and bit rate, cost of processing the compression and decompression, and system requirements. Highly compressed video may present visible or distracting artifacts. Other methods other than the prevalent DCT-based transform formats, such as fractal compression, matching pursuit and the use of a discrete wavelet transform (DWT), have been the subject of some research, but are typically not used in practical products. Wavelet compression is used in still-image coders and video coders without motion compensation. Interest in fractal compression seems to be waning, due to recent theoretical analysis showing a comparative lack of effectiveness of such methods. Inter-frame coding Inter-frame coding works by comparing each frame in the video with the previous one. Individual frames of a video sequence are compared from one frame to the next, and the video compression codec sends only the differences to the reference frame. If the frame contains areas where nothing has moved, the system can simply issue a short command that copies that part of the previous frame into the next one. If sections of the frame move in a simple manner, the compressor can emit a (slightly longer) command that tells the decompressor to shift, rotate, lighten, or darken the copy. This longer command still remains much shorter than intraframe compression. Usually, the encoder will also transmit a residue signal which describes the remaining more subtle differences to the reference imagery. Using entropy coding, these residue signals have a more compact representation than the full signal. In areas of video with more motion, the compression must encode more data to keep up with the larger number of pixels that are changing. Commonly during explosions, flames, flocks of animals, and in some panning shots, the high-frequency detail leads to quality decreases or to increases in the variable bitrate. Hybrid block-based transform formats Today, nearly all commonly used video compression methods (e.g., those in standards approved by the ITU-T or ISO) share the same basic architecture that dates back to H.261 which was standardized in 1988 by the ITU-T. They mostly rely on the DCT, applied to rectangular blocks of neighboring pixels, and temporal prediction using motion vectors, as well as nowadays also an in-loop filtering step. In the prediction stage, various deduplication and difference-coding techniques are applied that help decorrelate data and describe new data based on already transmitted data. Then rectangular blocks of (residue) pixel data are transformed to the frequency domain to ease targeting irrelevant information in quantization and for some spatial redundancy reduction. The discrete cosine transform (DCT) that is widely used in this regard was introduced by N. Ahmed, T. Natarajan and K. R. Rao in 1974. In the main lossy processing stage, that data gets quantized in order to reduce information that is irrelevant to human visual perception. In the last stage statistical redundancy gets largely eliminated by an entropy coder which often applies some form of arithmetic coding. In an additional in-loop filtering stage various filters can be applied to the reconstructed image signal. By computing these filters also inside the encoding loop they can help compression because they can be applied to reference material before it gets used in the prediction process and they can be guided using the original signal. The most popular example are deblocking filters that blur out blocking artifacts from quantization discontinuities at transform block boundaries. History In 1967, A.H. Robinson and C. Cherry proposed a run-length encoding bandwidth compression scheme for the transmission of analog television signals. Discrete cosine transform (DCT), which is fundamental to modern video compression, was introduced by Nasir Ahmed, T. Natarajan and K. R. Rao in 1974. H.261, which debuted in 1988, commercially introduced the prevalent basic architecture of video compression technology. It was the first video coding format based on DCT compression, which would subsequently become the standard for all of the major video coding formats that followed. H.261 was developed by a number of companies, including Hitachi, PictureTel, NTT, BT and Toshiba. The most popular video coding standards used for codecs have been the MPEG standards. MPEG-1 was developed by the Motion Picture Experts Group (MPEG) in 1991, and it was designed to compress VHS-quality video. It was succeeded in 1994 by MPEG-2/H.262, which was developed by a number of companies, primarily Sony, Thomson and Mitsubishi Electric. MPEG-2 became the standard video format for DVD and SD digital television. In 1999, it was followed by MPEG-4/H.263, which was a major leap forward for video compression technology. It was developed by a number of companies, primarily Mitsubishi Electric, Hitachi and |
that they were being overshadowed by Lumumba and the MNC, Kasa-Vubu and the ABAKO leadership announced that they would be hosting their own rally in the capital on 4 January 1959. The municipal government (under Belgian domination) was given short notice, and communicated that only a "private meeting" would be authorised. On the scheduled day of the rally the ABAKO leadership told the crowd that had gathered that the event was postponed and that they should disperse. The mass was infuriated and instead began hurling stones at the police and pillaging European property, initiating three days of violent and destructive riots. The Force Publique, the colonial army, was called into service and suppressed the revolt with considerable brutality. In wake of the riots Kasa-Vubu and his lieutenants were arrested. Unlike earlier expressions of discontent, the grievances were conveyed primarily by uneducated urban residents, not évolués. Popular opinion in Belgium was one of extreme shock and surprise. An investigative commission found the riots to be the culmination of racial discrimination, overcrowding, unemployment, and wishes for more political self-determination. On 13 January the administration announced several reforms, and the Belgian King, Baudouin, declared that independence would be granted to the Congo in the future. Meanwhile, discontent surfaced among the MNC leadership, who were bothered by Lumumba's domination over the party's politics. Relations between Lumumba and Kalonji also grew tense, as the former was upset with how the latter was transforming the Kasai branch into an exclusively Luba group and antagonising other tribes. This culminated into the split of the party into the MNC-Lumumba/MNC-L under Lumumba and the MNC-Kalonji/MNC-K under Kalonji and Iléo. The latter began advocating federalism. Adoula left the organisation. Alone to lead his own faction and facing competition from ABAKO, Lumumba became increasingly strident in his demands for independence. Following an October riot in Stanleyville he was arrested. Nevertheless, the influence of himself and the MNC-L continued to grow rapidly. The party advocated for a strong unitary state, nationalism, and the termination of Belgian rule and began forming alliances with regional groups, such as the Kivu-based Centre du Regroupement Africain (CEREA). Though the Belgians supported a unitary system over the federal models suggested by ABAKO and CONAKAT, they and more moderate Congolese were unnerved by Lumumba's increasingly extremist attitudes. With the implicit support of the colonial administration, the moderates formed the Parti National du Progrès (PNP) under the leadership of Paul Bolya and Albert Delvaux. It advocated centralisation, respect for traditional elements, and close ties with Belgium. In southern Léopoldville Province, a socialist-federalist party, the Parti Solidaire Africain (PSA) was founded. Antoine Gizenga served as its president, and Cléophas Kamitatu was in charge of the Léopoldville Province chapter. Independence and the Congo Crisis (1960–65) Following the riots in Leopoldville 4–7 January 1959, and in Stanleyville on 31 October 1959, the Belgians realised they could not maintain control of such a vast country in the face of rising demands for independence. Belgian and Congolese political leaders held a Round Table Conference in Brussels beginning on 18 January 1960. At the end of the conference, on 27 January 1960, it was announced that elections would be held in the Congo on 22 May 1960, and full independence granted on 30 June 1960. The elections produced the nationalist Patrice Lumumba as prime minister, and Joseph Kasavubu as president. On independence the country adopted the name "Republic of the Congo" (République du Congo). The French colony of Middle Congo (Moyen Congo) also chose the name Republic of the Congo upon its independence, so the two countries are more commonly known as Congo-Léopoldville and Congo-Brazzaville, after their capital cities. In 1960, the country was very unstable—regional tribal leaders held far more power than the central government—and with the departure of the Belgian administrators, almost no skilled bureaucrats remained in the country. The first Congolese graduated from university only in 1956, and very few in the new nation had any idea how to manage a country of such size. On 5 July 1960, a military mutiny by Congolese soldiers against their European officers broke out in the capital and rampant looting began. On 11 July 1960 the richest province of the country, Katanga, seceded under Moise Tshombe. The United Nations sent 20,000 peacekeepers to protect Europeans in the country and try to restore order. Western paramilitaries and mercenaries, often hired by mining companies to protect their interests, also began to pour into the country. In this period Congo's second richest province, Kasai, also announced its independence on 8 August 1960. After trying to get help from the United States and the United Nations, Prime Minister Lumumba turned to the USSR for assistance. Nikita Khrushchev agreed to help, offering advanced weaponry and technical advisors. The United States viewed the Soviet presence as an attempt to take advantage of the situation and gain a proxy state in sub-Saharan Africa. UN forces were ordered to block any shipments of arms into the country. The United States also looked for a way to replace Lumumba as leader. President Kasavubu had clashed with Prime Minister Lumumba and advocated an alliance with the West rather than the Soviets. The U.S. sent weapons and CIA personnel to aid forces allied with Kasavubu and combat the Soviet presence. On 14 September 1960, with U.S. and CIA support, Colonel Joseph Mobutu overthrew the government and arrested Lumumba. A technocratic government, the College of Commissioners-General, was established. On 17 January 1961 Mobutu sent Lumumba to Élisabethville (now Lubumbashi), capital of Katanga. In full view of the press he was beaten and forced to eat copies of his own speeches. For three weeks afterward, he was not seen or heard from. Then Katangan radio announced implausibly that he had escaped and been killed by villagers. It was soon clear that in fact he had been tortured and killed along with two others shortly after his arrival. In 2001, a Belgian inquiry established that he had been shot by Katangan gendarmes in the presence of Belgian officers, under Katangan command. Lumumba was beaten, placed in front of a firing squad with two allies, cut up, buried, dug up and what remained was dissolved in acid. In Stanleyville, those loyal to the deposed Lumumba set up a rival government under Antoine Gizenga which lasted from 31 March 1961 until it was reintegrated on 5 August 1961. After some reverses, UN and Congolese government forces succeeded in recapturing the breakaway provinces of South Kasai on 30 December 1961, and Katanga on 15 January 1963. A new crisis erupted in the Simba Rebellion of 1964-1965 which saw half the country taken by the rebels. European mercenaries, US, and Belgian troops were called in by the Congolese government to defeat the rebellion. Zaire (1965–97) Unrest and rebellion plagued the government until November 1965, when Lieutenant General Joseph-Désiré Mobutu, by then commander in chief of the national army, seized control of the country and declared himself president for the next five years. Mobutu quickly consolidated his power, despite the Stanleyville mutinies of 1966 and 1967, and was elected unopposed as president in 1970 for a seven-year term. Embarking on a campaign of cultural awareness, President Mobutu renamed the country the "Republic of Zaire" in 1971 and required citizens to adopt African names and drop their French-language ones. The name comes from Portuguese, adapted from the Kongo word nzere or nzadi ("river that swallows all rivers"). Among other changes, Leopoldville became Kinshasa and Katanga Shaba. Relative peace and stability prevailed until 1977 and 1978 when Katangan Front for Congolese National Liberation rebels, based in the Angolan People's Republic, launched the Shaba I and II invasions into the southeast Shaba region. These rebels were driven out with the aid of French and Belgian paratroopers plus Moroccan troops. An Inter-African Force remained in the region for some time afterwards. Zaire remained a one-party state in the 1980s. Although Mobutu successfully maintained control during this period, opposition parties, most notably the Union pour la Démocratie et le Progrès Social (UDPS), were active. Mobutu's attempts to quell these groups drew significant international criticism. As the Cold War came to a close, internal and external pressures on Mobutu increased. In late 1989 and early 1990, Mobutu was weakened by a series of domestic protests, by heightened international criticism of his regime's human rights practices, by a faltering economy, and by government corruption, most notably his own massive embezzlement of government funds for personal use. In April 1990, Mobutu declared the Third Republic, agreeing to a limited multi-party system with free elections and a constitution. As details of the reforms were delayed, soldiers in September 1991 began looting Kinshasa to protest their unpaid wages. Two thousand French and Belgian troops, some of whom were flown in on U.S. Air Force planes, arrived to evacuate the 20,000 endangered foreign nationals in Kinshasa. In 1992, after previous similar attempts, the long-promised Sovereign National Conference was staged, encompassing over 2,000 representatives from various political parties. The conference gave itself a legislative mandate and elected Archbishop Laurent Monsengwo Pasinya as its chairman, along with Étienne Tshisekedi wa Mulumba, leader of the UDPS, as prime minister. By the end of the year Mobutu had created a rival government with its own prime minister. The ensuing stalemate produced a compromise merger of the two governments into the High Council of Republic-Parliament of Transition (HCR-PT) in 1994, with Mobutu as head of state and Kengo Wa Dondo as prime minister. Although presidential and legislative elections were scheduled repeatedly over the next two years, they never took place. Civil Wars (1996-2003) First Congo War (1996–97) By 1996, tensions from the war and genocide in neighboring Rwanda had spilled over into Zaire. Rwandan Hutu militia forces (Interahamwe) who had fled Rwanda following the ascension of a Tutsi-led government had been using Hutu refugee camps in eastern Zaire as bases for incursions into Rwanda. In October 1996 Rwandan forces attacked refugee camps in the Rusizi River plain near the intersection of the Congolese, Rwandan and Burundi borders meet, scattering refugees. They took Uvira, then Bukavu, Goma and Mugunga. Hutu militia forces soon allied with the Zairian armed forces (FAZ) to launch a campaign against Congolese ethnic Tutsis in eastern Zaire. In turn, these Tutsis formed a militia to defend themselves against attacks. When the Zairian government began to escalate the massacres in November 1996, Tutsi militias erupted in rebellion against Mobutu. The Tutsi militia was soon joined by various opposition groups and supported by several countries, including Rwanda and Uganda. This coalition, led by Laurent-Desire Kabila, became known as the Alliance des Forces Démocratiques pour la Libération du Congo-Zaïre (AFDL). The AFDL, now seeking the broader goal of ousting Mobutu, made significant military gains in early 1997. Various Zairean politicians who had unsuccessfully opposed the dictatorship of Mobutu for many years now saw an opportunity for them in the invasion of Zaire by two of the region's strongest military forces. Following failed peace talks between Mobutu and Kabila in May 1997, Mobutu left the country on 16 May. The AFDL entered Kinshasa unopposed a day later, and Kabila named himself president, reverting the name of the country to the Democratic Republic of the Congo. He marched into Kinshasa on 20 May and consolidated power around himself and the AFDL. In September 1997, Mobutu died in exile in Morocco. Second Congo War (1998–2003) Kabila demonstrated little ability to manage the problems of his country, and lost his allies. To counterbalance the power and influence of Rwanda in DRC, Ugandan troops created another rebel movement called the Movement for the Liberation of Congo (MLC), led by the Congolese warlord Jean-Pierre Bemba. They attacked in August 1998, backed by Rwandan and Ugandan troops. Soon afterwards, Angola, Namibia, and Zimbabwe became involved militarily in the Congo, with Angola and Zimbabwe supporting the government. While the six African governments involved in the war signed a ceasefire accord in Lusaka in July 1999, the Congolese rebels did not and the ceasefire broke down within months. Kabila was assassinated in 2001 by a bodyguard called Rashidi Kasereka, 18, who was then shot dead, according to Justice Minister Mwenze Kongolo. Another account of the assassination says that the real killer escaped. Kabila was succeeded by his son, Joseph. Upon taking office, Kabila called for multilateral peace talks to end the war. Kabila partly succeeded when a further peace deal was brokered between him, Uganda, and Rwanda leading to the apparent withdrawal of foreign troops. Currently, the Ugandans and the MLC still hold a wide section of the north of the country; Rwandan forces and its front, the Rassemblement Congolais pour la Démocratie (RCD) control a large section of the east; and government forces or their allies hold the west and south of the country. There were reports that the conflict is being prolonged as a cover for extensive looting of the substantial natural resources in the country, including diamonds, copper, zinc, and coltan. The conflict was reignited in January 2002 by ethnic clashes in the northeast and both Uganda and Rwanda then halted their withdrawal and sent in more troops. Talks between Kabila and the rebel leaders, held in Sun City, lasted a full six weeks, beginning in April 2002. In June, they signed a peace accord under which Kabila would share power with former rebels. By June 2003, all foreign armies except those of Rwanda had pulled out of Congo. Few people in the Congo have been unaffected by the conflict. A survey conducted in 2009 by the ICRC and Ipsos shows that three-quarters (76%) of the people interviewed have been affected in some way–either personally or due to the wider consequences of armed conflict. The response of the international community has been incommensurate with the scale of the disaster resulting from the war in the Congo. Its support for political and diplomatic efforts to end the war has been relatively consistent, but it has taken no effective steps to abide by repeated pledges to demand accountability for the war crimes and crimes against humanity that were routinely committed in Congo. The United Nations Security Council and the U.N. Secretary-General have frequently denounced human rights abuses and the humanitarian disaster that the war unleashed on the local population, but have shown little will to tackle the responsibility of occupying powers for the atrocities taking place in areas under their control, areas where the worst violence in the country took place. In particular Rwanda and Uganda have escaped any significant sanction for their role. Joseph Kabila period Transitional government (2003–06) DR Congo had a transitional government in July 2003 until the election was over. A constitution was approved by voters and on 30 July 2006 the Congo held its first multi-party elections since independence in 1960. Joseph Kabila took 45% of the votes and his opponent Jean-Pierre Bemba 20%. That was the origin of a fight between the two parties from 20–22 August 2006 in the streets of the capital, Kinshasa. Sixteen people died before policemen and MONUC took control of the city. A new election was held on 29 October 2006, which Kabila won with 70% of the vote. Bemba has decried election "irregularities." On 6 December 2006 Joseph Kabila was sworn in as President. Kabila overstays his term In December 2011, Joseph Kabila was re-elected for a second term as president. After the results were announced on 9 December, there was violent unrest in Kinshasa and Mbuji-Mayi, where official tallies showed that a strong majority had voted for the opposition candidate Etienne Tshisekedi. Official observers from the Carter Center reported that returns from almost 2,000 polling stations in areas where support for Tshisekedi was strong had been lost and not included in the official results. They described the election as lacking credibility. On 20 December, Kabila was sworn in for a second term, promising to invest in infrastructure and public services. However, Tshisekedi maintained that the result of the election was illegitimate and said that he intended also to "swear himself in" as president. On 19 January 2015 protests led by students at the University of Kinshasa broke out. The protests began following the announcement of a proposed law that would allow Kabila to remain in power until a national census can be conducted (elections had been planned for 2016). By Wednesday 21 January clashes between police and protesters had claimed at least 42 lives (although the government claimed only 15 people had been killed). Similarly, in September 2016, violent protests were met with brutal force by the police and Republican Guard soldiers. Opposition groups claim 80 dead, including the Students' Union leader. From Monday 19 September Kinshasa residents, as well as residents elsewhere in Congo, where mostly confined to their homes. Police arrested anyone remotely connected to the opposition as well as innocent onlookers. Government propaganda, on television, and actions of covert government groups in the streets, acted against opposition as well as foreigners. The president's mandate was due to end on 19 December 2016, but no plans were made to elect a replacement at that time and this caused further protests. Félix Tshisekedi Presidency (2019-) On 30 December 2018 the presidential election to determine the successor to Kabila was held. On 10 January 2019, the electoral commission announced opposition candidate Félix Tshisekedi as the winner of the vote. He was officially sworn in as President on 24 January 2019. in the ceremony of taking of the office Félix Tshisekedi appointed Vital Kamerhe as his chief of staff. In June 2020, chief of staff Vital Kamerhe was found guilty of embezzling public funds and he was sentenced to 20 years in prison. The political allies of former president Joseph Kabila, who stepped down in January 2019, maintained control of key ministries, the legislature, judiciary and security services. However, President Felix Tshisekedi succeeded to strengthen his hold on power. In a series of moves, he won over more legislators, gaining the support of almost 400 out of 500 members of the National Assembly. The pro-Kabila speakers of both houses of parliament were forced out. In April 2021, the new government was formed without the supporters of Kabila. President Felix Tshisekedi succeeded to oust the last remaining elements of his government who were loyal to former leader Joseph Kabila. In January 2021, DRC's President Félix Tshisekedi pardoned all those convicted in the murder of Laurent-Désiré Kabila in 2001. Colonel Eddy Kapend and his co-defendants, who have been incarcerated for 15 years, were released. Continued conflicts The inability of the state and the world's largest United Nations peacekeeping force to provide security throughout the vast country has led to the emergence of up to 120 armed groups by 2018, perhaps the largest number in the world. Armed groups are often accused of being proxies or being supported by regional governments interested in Eastern Congo's vast mineral wealth. Some argue that much of the lack of security by the national army is strategic on the part of the government, who let the army profit from illegal logging and mining operations in return for loyalty. Different rebel groups often target civilians by ethnicity and militias often become oriented around ethnic local militias known as "Mai-Mai". Conflict in Kivu (2004-present) Laurent Nkunda with other soldiers from RCD-Goma who were integrated into the army defected and called themselves the National Congress for the Defence of the People (CNDP). Starting in 2004, CNDP, believed to be backed by Rwanda as a way to tackle the Hutu group Democratic Forces for the Liberation of Rwanda (FDLR), rebelled against the government, claiming to protect the Banyamulenge (Congolese Tutsis). In 2009, after a deal between the DRC and Rwanda, Rwandan troops entered the DRC and arrested Nkunda and were allowed to pursue FDLR militants. The CNDP signed a peace treaty with the government where its soldiers would be integrated into the national army. In April 2012, the leader of the CNDP, Bosco Ntaganda and troops loyal to him mutinied, claiming a violation of the peace treaty and formed a rebel group, the March 23 Movement (M23), which was believed to be backed by Rwanda. On 20 November 2012, M23 took control of Goma, a provincial capital with a population of one million people. The UN authorized the Force Intervention Brigade (FIB), which was the first UN peacekeeping force with a mandate to neutralize opposition rather than a defensive mandate, and the FIB quickly defeated M23. The FIB was then to fight the FDLR but were hampered by the efforts of the Congolese government, who some believe tolerate the FDLR as a counterweight to Rwandan interests. Since 2017, fighters from M23, most of whom had fled into Uganda and Rwanda (both were believed to have supported them), started crossing back into DRC with the rising crisis over Kabila's extension of his term limit. DRC claimed of clashes with M23. After rising insecurity, President Tshisekedi declared a "state of siege" or state of emergency in North Kivu, as well as Ituri province, in the first such declaration since the country's independence. The military and police took over positions from civilian authorities and some saw it as a | the entire west coast of Africa targeted, but the region around the mouth of the Congo suffered the most intensive enslavement. Over a strip of coastline about long, about 4 million people were enslaved and sent across the Atlantic to sugar plantations in Brazil, the US and the Caribbean. From 1780 onwards, there was a higher demand for slaves in the US which led to more people being enslaved. By 1780, more than 15,000 people were shipped annually from the Loango Coast, north of the Congo. In 1870, explorer Henry Morton Stanley arrived in and explored what is now the DR Congo. Belgian colonization of DR Congo began in 1885 when King Leopold II founded and ruled the Congo Free State. However, de facto control of such a huge area took decades to achieve. Many outposts were built to extend the power of the state over such a vast territory. In 1885, the Force Publique was set up, a colonial army with white officers and black soldiers. In 1886, Leopold made Camille Jansen the first Belgian governor-general of Congo. Over the late 19th century, various Christian (including Catholic and Protestant) missionaries arrived intending to convert the local population. A railway between Matadi and Stanley Pool was built in the 1890s. Reports of widespread murder, torture, and other abuses in the rubber plantations led to international and Belgian outrage and the Belgian government transferred control of the region from Leopold II and established the Belgian Congo in 1908. After an uprising by the Congolese people, Belgium surrendered and this led to the independence of the Congo in 1960. However, the Congo remained unstable because regional leaders had more power than the central government, with Katanga attempting to gain independence with Belgian support. Prime Minister Patrice Lumumba tried to restore order with the aid of the Soviet Union as part of the Cold War, causing the United States to support a coup led by Colonel Joseph Mobutu in 1965. Mobutu quickly seized complete power of the Congo and renamed the country Zaire. He sought to Africanize the country, changing his own name to Mobutu Sese Seko, and demanded that African citizens change their Western names to traditional African names. Mobutu sought to repress any opposition to his rule, which he successfully did throughout the 1980s. However, with his regime weakened in the 1990s, Mobutu was forced to agree to a power-sharing government with the opposition party. Mobutu remained the head of state and promised elections within the next two years that never took place. During the First Congo War, Rwanda invaded Zaire, in which Mobutu lost his power during this process. In 1997, Laurent-Désiré Kabila took power and renamed the country the Democratic Republic of the Congo. Afterward, the Second Congo War broke out, resulting in a regional war in which many different African nations took part and in which millions of people were killed or displaced. Kabila was assassinated by his bodyguard in 2001, and his son, Joseph, succeeded him and was later elected president by the Congolese government in 2006. Joseph Kabila quickly sought peace. Foreign soldiers remained in the Congo for a few years and a power-sharing government between Joseph Kabila and the opposition party was set up. Joseph Kabila later resumed complete control over the Congo and was re-elected in a disputed election in 2011. In 2018, Félix Tshisekedi was elected President; in the first peaceful transfer of power since independence. Early history The area now known as the Democratic Republic of the Congo was populated as early as 80,000 years ago, as shown by the 1988 discovery of the Semliki harpoon at Katanda, one of the oldest barbed harpoons ever found, which is believed to have been used to catch giant river catfish. During its recorded history, the area has also been known as Congo, Congo Free State, Belgian Congo, and Zaire. The Kingdom of Kongo existed from the 14th to the early 19th century. Until the arrival of the Portuguese it was the dominant force in the region along with the Kingdom of Luba, the Kingdom of Lunda, the Mongo people and the Anziku Kingdom. Colonial rule Congo Free State (1885–1908) The Congo Free State was a corporate state privately controlled by Leopold II of Belgium through the Association Internationale africaine, a non-governmental organization. Leopold was the sole shareholder and chairman. The state included the entire area of the present the Democratic Republic of the Congo. Under Leopold II, the Congo Free State became one of the most infamous international scandals of the turn of the twentieth century. The report of the British Consul Roger Casement led to the arrest and punishment of white officials who had been responsible for cold-blooded killings during a rubber-collecting expedition in 1900, including a Belgian national who caused the shooting of at least 122 Congolese natives. Estimates of the total death toll vary considerably. The first census was only done in 1924, so it is even more difficult to quantify the population loss of the period. Roger Casement's famous 1904 report estimated ten million people. According to Casement's report, indiscriminate "war", starvation, reduction of births and Tropical diseases caused the country's depopulation. European and U.S. press agencies exposed the conditions in the Congo Free State to the public in 1900. By 1908 public and diplomatic pressure had led Leopold II to annex the Congo as the Belgian Congo colony. Belgian Congo (1908–60) On 15 November 1908 King Leopold II of Belgium formally relinquished personal control of the Congo Free State. The renamed Belgian Congo was put under the direct administration of the Belgian government and its Ministry of Colonies. Belgian rule in the Congo was based around the "colonial trinity" (trinité colonial) of state, missionary and private company interests. The privileging of Belgian commercial interests meant that large amounts of capital flowed into the Congo and that individual regions became specialized. The interests of the government and private enterprise became closely tied; the state helped companies break strikes and remove other barriers imposed by the indigenous population. The country was split into nesting, hierarchically organized administrative subdivisions, and run uniformly according to a set "native policy" (politique indigène)—in contrast to the British and the French, who generally favored the system of indirect rule whereby traditional leaders were retained in positions of authority under colonial oversight. There was also a high degree of racial segregation. Large numbers of white immigrants who moved to the Congo after the end of World War II came from across the social spectrum, but were nonetheless always treated as superior to blacks. During the 1940s and 1950s, the Congo experienced an unprecedented level of urbanization and the colonial administration began various development programs aimed at making the territory into a "model colony". Notable advances were made in treating diseases such as African trypanosomiasis. One of the results of these measures was the development of a new middle class of Europeanised African évolués in the cities. By the 1950s the Congo had a wage labor force twice as large as that in any other African colony. The Congo's rich natural resources, including uranium—much of the uranium used by the U.S. nuclear programme during World War II was Congolese—led to substantial interest in the region from both the Soviet Union and the United States as the Cold War developed. Rise in Congolese political activity During the latter stages of World War II a new social stratum emerged in the Congo, known as the évolués. Forming an African middle class in the colony, they held skilled positions (such as clerks and nurses) made available by the economic boom. While there were no universal criteria for determining évolué status, it was generally accepted that one would have "a good knowledge of French, adhere to Christianity, and have some form of post-primary education." Early on in their history, most évolués sought to use their unique status to earn special privileges in the Congo. Since opportunities for upward mobility through the colonial structure were limited, the évolué class institutionally manifested itself in elite clubs through which they could enjoy trivial privileges that made them feel distinct from the Congolese "masses". Additional groups, such as labor unions, alumni associations, and ethnic syndicates, provided other Congolese the means of organization. Among the most important of these was the Alliance des Bakongo (ABAKO), representing the Kongo people of the Lower Congo. However, they were restricted in their actions by the administration. While white settlers were consulted in the appointment of certain officials, the Congolese had no means of expressing their beliefs through the governing structures. Though native chiefs held legal authority in some jurisdictions, in practice they were used by the administration to further its own policies. Up into the 1950s, most évolués were concerned only with social inequalities and their treatment by the Belgians. Questions of self-government were not considered until 1954 when ABAKO requested that the administration consider a list of suggested candidates for a Léopoldville municipal post. That year the association was taken over by Joseph Kasa-Vubu, and under his leadership, it became increasingly hostile to the colonial authority and sought autonomy for the Kongo regions in the Lower Congo. In 1956 a group of Congolese intellectuals under the tutelage of several European academics issued a manifesto calling for a transition to independence over the course of 30 years. The ABAKO quickly responded with a demand for "immediate independence". The Belgian government was not prepared to grant the Congo independence and even when it started realizing the necessity of a plan for decolonization in 1957, it was assumed that such a process would be solidly controlled by Belgium. In December 1957 the colonial administration instituted reforms that permitted municipal elections and the formation of political parties. Some Belgian parties attempted to establish branches in the colony, but these were largely ignored by the population in favour of Congolese-initiated groups. Nationalism fermented in 1958 as more évolués began interacting with others outside of their own locales and started discussing the future structures of a post-colonial Congolese state. Nevertheless, most political mobilisation occurred along tribal and regional divisions. In Katanga, various tribal groups came together to form the Confédération des associations tribales du Katanga (CONAKAT) under the leadership of Godefroid Munongo and Moïse Tshombe. Hostile to immigrant peoples, it advocated provincial autonomy and close ties with Belgium. Most of its support was rooted in individual chiefs, businessmen, and European settlers of southern Katanga. It was opposed by Jason Sendwe's Association Générale des Baluba du Katanga (BALUBAKAT). In October 1958 a group of Léopoldville évolués including Patrice Lumumba, Cyrille Adoula and Joseph Iléo established the Mouvement National Congolais (MNC). Diverse in membership, the party sought to peacefully achieve Congolese independence, promote the political education of the populace, and eliminate regionalism. The MNC drew most of its membership from the residents of the eastern city of Stanleyville, where Lumumba was well known, and from the population of the Kasai Province, where efforts were directed by a Muluba businessman, Albert Kalonji. Belgian officials appreciated its moderate and anti-separatist stance and allowed Lumumba to attend the All-African Peoples' Conference in Accra, Ghana, in December 1958 (Kasa-Vubu was informed that the documents necessary for his travel to the event were not in order and was not permitted to go). Lumumba was deeply impressed by the Pan-Africanist ideals of Ghanaian President Kwame Nkrumah and returned to the Congo with a more radical party programme. He reported on his trip during a widely attended rally in Léopoldville and demanded the country's "genuine" independence. Fearing that they were being overshadowed by Lumumba and the MNC, Kasa-Vubu and the ABAKO leadership announced that they would be hosting their own rally in the capital on 4 January 1959. The municipal government (under Belgian domination) was given short notice, and communicated that only a "private meeting" would be authorised. On the scheduled day of the rally the ABAKO leadership told the crowd that had gathered that the event was postponed and that they should disperse. The mass was infuriated and instead began hurling stones at the police and pillaging European property, initiating three days of violent and destructive riots. The Force Publique, the colonial army, was called into service and suppressed the revolt with considerable brutality. In wake of the riots Kasa-Vubu and his lieutenants were arrested. Unlike earlier expressions of discontent, the grievances were conveyed primarily by uneducated urban residents, not évolués. Popular opinion in Belgium was one of extreme shock and surprise. An investigative commission found the riots to be the culmination of racial discrimination, overcrowding, unemployment, and wishes for more political self-determination. On 13 January the administration announced several reforms, and the Belgian King, Baudouin, declared that independence would be granted to the Congo in the future. Meanwhile, discontent surfaced among the MNC leadership, who were bothered by Lumumba's domination over the party's politics. Relations between Lumumba and Kalonji also grew tense, as the former was upset with how the latter was transforming the Kasai branch into an exclusively Luba group and antagonising other tribes. This culminated into the split of the party into the MNC-Lumumba/MNC-L under Lumumba and the MNC-Kalonji/MNC-K under Kalonji and Iléo. The latter began advocating federalism. Adoula left the organisation. Alone to lead his own faction and facing competition from ABAKO, Lumumba became increasingly strident in his demands for independence. Following an October riot in Stanleyville he was arrested. Nevertheless, the influence of himself and the MNC-L continued to grow rapidly. The party advocated for a strong unitary state, nationalism, and the termination of Belgian rule and began forming alliances with regional groups, such as the Kivu-based Centre du Regroupement Africain (CEREA). Though the Belgians supported a unitary system over the federal models suggested by ABAKO and CONAKAT, they and more moderate Congolese were unnerved by Lumumba's increasingly extremist attitudes. With the implicit support of the colonial administration, the moderates formed the Parti National du Progrès (PNP) under the leadership of Paul Bolya and Albert Delvaux. It advocated centralisation, respect for traditional elements, and close ties with Belgium. In southern Léopoldville Province, a socialist-federalist party, the Parti Solidaire Africain (PSA) was founded. Antoine Gizenga served as its president, and Cléophas Kamitatu was in charge of the Léopoldville Province chapter. Independence and the Congo Crisis (1960–65) Following the riots in Leopoldville 4–7 January 1959, and in Stanleyville on 31 October 1959, the Belgians realised they could not maintain control of such a vast country in the face of rising demands for independence. Belgian and Congolese political leaders held a Round Table Conference in Brussels beginning on 18 January 1960. At the end of the conference, on 27 January 1960, it was announced that elections would be held in the Congo on 22 May 1960, and full independence granted on 30 June 1960. The elections produced the nationalist Patrice Lumumba as prime minister, and Joseph Kasavubu as president. On independence the country adopted the name "Republic of the Congo" (République du Congo). The French colony of Middle Congo (Moyen Congo) also chose the name Republic of the Congo upon its independence, so the two countries are more commonly known as Congo-Léopoldville and Congo-Brazzaville, after their capital cities. In 1960, the country was very unstable—regional tribal leaders held far more power than the central government—and with the departure of the Belgian administrators, almost no skilled bureaucrats remained in the country. The first Congolese graduated from university only in 1956, and very few in the new nation had any idea how to manage a country of such size. On 5 July 1960, a military mutiny by Congolese soldiers against their European officers broke out in the capital and rampant looting began. On 11 July 1960 the richest province of the country, Katanga, seceded under Moise Tshombe. The United Nations sent 20,000 peacekeepers to protect Europeans in the country and try to restore order. Western paramilitaries and mercenaries, often hired by mining companies to protect their interests, also began to pour into the country. In this period Congo's second richest province, Kasai, also announced its independence on 8 August 1960. After trying to get help from the United States and the United Nations, Prime Minister Lumumba turned to the USSR for assistance. Nikita Khrushchev agreed to help, offering advanced weaponry and technical advisors. The United States viewed the Soviet presence as an attempt to take advantage of the situation and gain a proxy state in sub-Saharan Africa. UN forces were ordered to block any shipments of arms into the country. The United States also looked for a way to replace Lumumba as leader. President Kasavubu had clashed with Prime Minister Lumumba and advocated an alliance with the West rather than the Soviets. The U.S. sent weapons and CIA personnel to aid forces allied with Kasavubu and combat the Soviet presence. On 14 September 1960, with U.S. and CIA support, Colonel Joseph Mobutu overthrew the government and arrested Lumumba. A technocratic government, the College of Commissioners-General, was established. On 17 January 1961 Mobutu sent Lumumba to Élisabethville (now Lubumbashi), capital of Katanga. In full view of the press he was beaten and forced to eat copies of his own speeches. For three weeks afterward, he was not seen or heard from. Then Katangan radio announced implausibly that he had escaped and been killed by villagers. It was soon clear that in fact he had been tortured and killed along with two others shortly after his arrival. In 2001, a Belgian inquiry established that he had been shot by Katangan gendarmes in the presence of Belgian officers, under Katangan command. Lumumba was beaten, placed in front of a firing squad with two allies, cut up, buried, dug up and what remained was dissolved in acid. In Stanleyville, those loyal to the deposed Lumumba set up a rival government under Antoine Gizenga which lasted from 31 March 1961 until it was reintegrated on 5 August 1961. After some reverses, UN and Congolese government forces succeeded in recapturing the breakaway provinces of South Kasai on 30 December 1961, and Katanga on 15 January 1963. A new crisis erupted in the Simba Rebellion of 1964-1965 which saw half the country taken by the rebels. European mercenaries, US, and Belgian troops were called in by the Congolese government to defeat the rebellion. Zaire (1965–97) Unrest and rebellion plagued the government until November 1965, when Lieutenant General Joseph-Désiré Mobutu, by then commander in chief of the national army, seized control of the country and declared himself president for the next five years. Mobutu quickly consolidated his power, despite the Stanleyville mutinies of 1966 and 1967, and was elected unopposed as president in 1970 for a seven-year term. Embarking on a campaign of cultural awareness, President Mobutu renamed the country the "Republic of Zaire" in 1971 and required citizens to adopt African names and drop their French-language ones. The name comes from Portuguese, adapted from the Kongo word nzere or nzadi ("river that swallows all rivers"). Among other changes, Leopoldville became Kinshasa and Katanga Shaba. Relative peace and stability prevailed until 1977 and 1978 when Katangan Front for Congolese National Liberation rebels, based in the Angolan People's Republic, launched the Shaba I and II invasions into the southeast Shaba region. These rebels were driven out with the aid of French and Belgian paratroopers plus Moroccan troops. An Inter-African Force remained in the region for some time afterwards. Zaire remained a one-party state in the 1980s. Although Mobutu successfully maintained control during this period, opposition parties, most notably the Union pour la Démocratie et le Progrès Social (UDPS), were active. Mobutu's attempts to quell these groups drew significant international criticism. As the Cold War came to a close, internal and external pressures on Mobutu increased. In late 1989 and early 1990, Mobutu was weakened by a series of domestic protests, by heightened international criticism of his regime's human rights |
mixtures of savanna grasses and woodlands. The southern uplands region, like the basin, constitutes about a third of the DRC's territory. The area slopes from south to north, starting at about near the Angolan border and falling to about near the basin. Vegetation cover in the southern uplands territory is more varied than that of the northern uplands. In some areas, woodland is dominant; in others, savanna grasses predominate. South of the basin, along the streams flowing into the Kasai River are extensive gallery forests. In the far southeast, most of the former Katanga Province is characterized by somewhat higher plateaus and low mountains. The westernmost section of the DRC, a partly forested panhandle reaching the Atlantic Ocean, is an extension of the southern uplands that drops sharply to a very narrow shore about long. In the much narrower northern uplands, the cover is largely savanna, and woodlands are rarer. The average elevation of this region is about , but it rises as high as where it meets the western edge of the eastern highlands. The eastern highlands region is the highest and most rugged portion of the country. It extends for more than from above Lake Albert to the country's southern tip and varies in width from . Its hills and mountains range in altitude from about to more than . The western arm of the Great Rift Valley forms a natural eastern boundary to this region. The eastern border of the DRC extends through the valley and its system of lakes, which are separated from each other by plains situated between high mountain ranges. In this region, changes in elevation bring marked changes in vegetation, which ranges from montane savanna to heavy montane forest. The Rwenzori Mountains between lakes Albert and Edward constitutes the highest range in Africa. The height and location of these mountains on the equator make for a varied and spectacular flora. Rivers and lakes The Congo River and its tributaries drain this basin and provide the country with the most extensive network of navigable waterways in Africa. wide at the mid-point of its length, the river carries a volume of water that is second only to the Amazon's. Its flow is unusually regular because it is fed by rivers and streams from both sides of the equator; the complementary alternation of rainy and dry seasons on each side of the equator guarantees a regular supply of water for the main channel. At points where navigation is blocked by rapids and waterfalls, the sudden descent of the river creates a hydroelectric potential greater than that found in any other river system on earth. Most of the DRC is served by the Congo River system, a fact that has facilitated both trade and outside penetration. Its network of waterways is dense and evenly distributed through the country, with three exceptions: northeastern Mayombe in Kongo Central in the west, which is drained by a small coastal river called the Shilango; a strip of land on the eastern border adjoining lakes Edward and Albert, which is part of the Nile River basin; and a small part of the extreme southeastern DRC, which lies in the Zambezi River basin and drains into the Indian Ocean. Most of the DRC's lakes are also part of the Congo River basin. In the west are Lac Mai-Ndombe and Lac Tumba, which are remnants of a huge interior lake that once occupied the entire basin prior to the breach of the basin's edge by the Congo River and the subsequent drainage of the interior. In the southeast, Lake Mweru straddles the border with Zambia. On the eastern frontier, Lac Kivu, Central Africa's highest lake and a key tourist center, and Lake Tanganyika, just south of Lac Kivu, both feed into the Lualaba River, the name often given to the upper extension of the Congo River. Only the waters of the eastern frontier's northernmost great lakes, Edward and Albert, drain north, into the Nile Basin. Climate Climate ranges from tropical rain forest in the Congo River basin to tropical wet-and-dry in the southern uplands to tropical highland in eastern areas above in elevation. In general, temperatures and humidity are quite high. The highest and least variable temperatures are to be found in the equatorial forest, where daytime highs range between | geographic regions may be defined in terms of terrain and patterns of natural vegetation, namely the central Congo Basin, the uplands north and south of the basin, and the eastern highlands. The country's core region is the central Congo Basin. Having an average elevation of about , it measures roughly , constituting about a third of the DRC's territory. Much of the forest within the basin is swamp, and still more of it consists of a mixture of marshes and firm land. North and south of the basin lie higher plains and, occasionally, hills covered with varying mixtures of savanna grasses and woodlands. The southern uplands region, like the basin, constitutes about a third of the DRC's territory. The area slopes from south to north, starting at about near the Angolan border and falling to about near the basin. Vegetation cover in the southern uplands territory is more varied than that of the northern uplands. In some areas, woodland is dominant; in others, savanna grasses predominate.

Given the situation in the country and the condition of state structures, it is extremely difficult to obtain reliable data however evidence suggests that DRC continues to be a destination country for immigrants in spite of recent declines. Immigration is seen to be very diverse in nature, with refugees and asylum-seekers - products of the numerous and violent conflicts in the Great Lakes Region - constituting an important subset of the population in the country. Additionally, the country's large mine operations attract migrant workers from Africa and beyond and there is considerable migration for commercial activities from other African countries and the rest of the world, but these movements are not well studied. Transit migration towards South Africa and Europe also plays a role. Immigration in the DRC has decreased steadily over the past two decades, most likely as a result of the armed violence that the country has experienced. According to the International Organization for Migration, the number of immigrants in the DRC has declined from just over 1 million in 1960, to 754,000 in 1990, to 480,000 in 2005, to an estimated 445,000 in 2010. Valid figures are not available on migrant workers in particular, partly due to the predominance of the informal economy in the DRC. Data are also lacking on irregular immigrants, however given neighbouring country ethnic links to nationals of the DRC, irregular migration is assumed to be a significant phenomenon in the country. Figures on the number of Congolese nationals abroad vary greatly depending on the source, from 3 to 6 million. This discrepancy is due to a lack of official, reliable data. Emigrants from the DRC are above all long-term emigrants, the majority of which live within Africa and to a lesser extent in Europe; 79.7% and 15.3% respectively, according to estimates on 2000 data. Most Congolese emigrants however, remain in Africa, with new destination countries including South Africa and various points en route to Europe. In addition to being a host | (a lingua franca, or trade language), Kingwana (a dialect of Swahili), Kikongo ya leta, and Tshiluba. In total, there are over 200 ethnic languages. French is generally the language of instruction in schools. English is taught as a compulsory foreign language in Secondary and High Schools around the country. It is a required subject in the Faculty of Economics at major universities around the country and there are numerous language schools in the country that teach it. Former President Kabila himself is fluent in both English and French, as was his father. Religions A survey conducted by the Demographic and Health Surveys program in 2013-2014 indicated that Christians constituted 93.7% of the population (Catholics 29.7%, Protestants 26.8%, and other Christians 37.2%). An indigenous religion, Kimbanguism, was practiced by 2.8% of the population, while Muslims make up 1.2%. Another estimate (by the Pew Research Center in 2010) found Christianity was followed by 95.8% of the population. The CIA The World Factbook gives the following percentages: Roman Catholic 29.9%, Protestant 26.7%, Kimbanguist 2.8%, Other Christian 36.5%, Islam 1.3%, Other (includes Syncretic Sects and Indigenous beliefs) 2.7%. The Joshua Project, a Christian missionary organisation, gives the following percentages: Roman Catholic 43.9%, Protestant 24.8%, Other Christian 23.7%, Muslim 1.6%, Non-religious 0.6%, Hindu 0.1% other syncretic sects and indigenous beliefs 5.3%. Other demographic statistics These are some other demographic statistics according to the World Population Review in 2019. One birth every 9 seconds One death every 40 seconds One net migrant every 28 minutes Net gain of one person every 12 seconds The following demographic statistics are from the CIA World Factbook. Population 85,281,024 (July 2018 est.) 81.34 million Note: estimates for this country explicitly take into account the effects of excess mortality due to AIDS; this can result in lower life expectancy, higher infant mortality and death rates, lower population and growth rates, and changes in the distribution of population by age and gender than would otherwise be expected (July 2017 est.) Age structure 0-14 years: 41.25% (male 17,735,697 /female 17,446,866) 15-24 years: 21.46% (male 9,184,871 /female 9,117,462) 25-54 years: 30.96% (male 13,176,714 /female 13,225,429) 55-64 years: 3.63% (male 1,472,758 /female 1,625,637) 65 years and over: 2.69% (male 974,293 /female 1,321,297) (2018 est.)

Country comparison to the world: 105th -0.54 migrant(s)/1,000 population note: fighting between the Congolese Government and Uganda- and Rwanda-backed Congolese rebels spawned a regional war in DRC in August 1998, which left 2.33 million Congolese internally displaced and caused 412,000 Congolese refugees to flee to surrounding countries (2011 est.) Given the situation in the country and the condition of state structures, it is extremely difficult to obtain reliable data however evidence suggests that DRC continues to be a destination country for immigrants in spite of recent declines. Immigration is seen to be very diverse in nature, with refugees and asylum-seekers - products of the numerous and violent conflicts in the Great Lakes Region - constituting an important subset of the population in the |
products, mineral resources and dirty money." Ethnic rivalries were made worse because of economic interests and looting and coltan smuggling took place. Illegal monopolies formed in the country where they used forced labor for children to mine or work as soldiers. National parks were overrun with people looking to exploit minerals and resources. Increased poverty and hunger from the war and that increased the hunting of rare wildlife. Education was denied when the country was under foreign control and very few people make money off the minerals in the country. The national resources are not the root cause for the continued fighting in the region, however, the competition has become an incentive to keep fighting.[1] The DRC's level of economic freedom is one of the lowest in the world, putting it in the repressed category. The armed militias fight with the government in the eastern section of the country over the mining sector or the corruption of the government, and weak policies lead to the instability of the economy. Human rights abuses also ruin economic activity; the DRC has a 7% unemployment rate, but still has one of the lowest GDP's per capita in the world. A major problem for people trying to start their own companies is that the minimum amount of capital needed to launch the company is five times the average annual income, and prices are regulated by the government, which almost forces people to have to work for the larger, more corrupt businesses; otherwise, they won't have work. It is hard for the DRC to encourage foreign trade because of the regulatory barriers. International relations Poor infrastructure, an uncertain legal framework, corruption, and lack of openness in government economic policy and financial operations remain a brake on investment and growth. A number of International Monetary Fund (IMF) and World Bank missions have met with the new government to help it develop a coherent economic plan but associated reforms are on hold. Faced with continued currency depreciation, the government resorted to more drastic measures and in January 1999 banned the widespread use of U.S. dollars for all domestic commercial transactions, a position it later adjusted. The government has been unable to provide foreign exchange for economic transactions, while it has resorted to printing money to finance its expenditure. Growth was negative in 2000 because of the difficulty of meeting the conditions of international donors, continued low prices of key exports, and post-coup instability. 125 companies in 2003 contributed to the conflict in DRC showing the corruption. World Bank With the help of the International Development Association the DRC has worked toward the reestablishment of social services. This is done by giving 15 million people access to basic health services and giving bed nets to prevent malaria from spreading to people. With the Emergency Demobilization and Reintegration Program more than 107,000 adults and 34,000 child soldiers stood down their militarized posture. The travel time from Lubumbashi to Kasomeno in Katanga went down from seven days to two hours because of the improved roads which led to the decrease of prices of main goods by 60%. With the help of the IFC, KfW, and the EU the DRC improved its businesses by reducing the time it took to create a business by 51%, reducing the time it took to get construction permits by 54%, and reducing the number of taxes from 118 to 30. Improvements in health have been noticeable specifically that deliveries attended by trained staff jumped from 47 to 80%. In education 14 million textbooks were provided to children, completion rates of school have increased, and higher education was made available to students that chose to pursue it. Ease of doing business rank The Democratic Republic of Congo ranks 183 on the low end of the ease of doing business scale as ranked by the World Bank. This measures the difficulties of starting a business, enforcing contracts, paying taxes, resolving insolvency, protecting investors, trading across borders, getting credit, getting electricity, dealing with construction permits and registering property (World Bank 2014:8). International Monetary Fund The IMF plans on giving the DRC a $1 billion loan after its two-year suspension after it failed to give details about a mining deal from one of its state owned mines and an Israeli billionaire, Dan Gertler. The loan may be necessary for the country because there will be elections in December 2016 for the next president and the cost of funding this would range around $1.1 billion. The biggest problem with the vote is getting a country of 68 million people the size of Western Europe to polling stations with less than 1,860 miles of paved roads. Sectors Agriculture Agriculture is the mainstay of the economy, accounting for 57.9% of the GDP in 1997. Main cash crops include coffee, palm oil, rubber, cotton, sugar, tea, and cocoa. Food crops include cassava, plantains, maize, groundnuts, and rice. In 1996, agriculture employed 66% of the work force. The Democratic Republic of Congo produced, in 2018: 29.9 million tons of cassava (3rd largest producer in the world, second only to Nigeria and Thailand); 4.7 million tons of plantain (largest producer in the world); 2 million tons of maize; 1.1 million tons of palm oil; 990 thousand tons of rice; 384 thousand tons of sweet potato; 309 thousand tons of banana; 307 thousand tons of peanut; 213 thousand tons of mango (including mangosteen and guava); 213 thousand tons of papaya; 205 thousand tons of beans; 186 thousand tons of pineapple; 168 thousand tons of orange; 101 thousand tons of potato; In addition to smaller productions of other agricultural products, such as coffee (29 thousand tons), cocoa (3.6 thousand tons), natural rubber (14 thousand tons) and tea (3.6 thousand tons). Fishing The Democratic Republic of Congo also possesses 50 percent of Africa's forests and a river system that could provide hydro-electric power to the entire continent, according to a United Nations report on the country's strategic significance and its potential role as an economic power in central Africa. Fish are the single most important source of animal protein in the DRC. Total production of marine, river, and lake fisheries in 2003 was estimated at 222,965 tons, all but 5,000 tons from inland waters. PEMARZA, a state agency, carries on marine fishing. Forestry Forests cover 60 percent of the total land area. There are vast timber resources, and commercial development of the country's 61 million hectares (150 million acres) of exploitable wooded area is only beginning. The Mayumbe area of Bas-Congo was once the major center of timber exploitation, but forests in this area were nearly depleted. The more extensive forest regions of the central cuvette and of the Ubangi River valley have increasingly been tapped. Roundwood removals were estimated at 72,170,000 m2 in 2003, about 95 percent for fuel. Some 14 species are presently being harvested. Exports of forest products in 2003 totalled $25.7 million. Foreign capital is necessary in order for forestry to expand, and the government recognizes that changes in tax structure and export procedures will be needed to facilitate economic growth. Mining Rich in minerals, the DRC has a difficult history of predatory mineral extraction, which has been at the heart of many struggles within the country for many decades, but particularly in the 1990s. Although the economy of the Democratic Republic of the Congo, the second largest country in Africa who has historically relied heavily on mining, is no longer reflected in the GDP data as the mining industry has suffered from long-term "uncertain legal framework, corruption, and a lack of | commercial transactions, a position it later adjusted.

The informal sector . In her book entitled The Real Economy of Zaire, MacGaffey described a second, often illegal economy, "system D", which is outside the official economy (MacGaffey 1991:27). and therefore is not reflected in the GDP. Exploitation of mineral substances by companies The economy of the second largest country in Africa relies heavily on mining. The Congo is the world's largest producer of cobalt ore, and a major producer of copper and industrial diamonds. The Congo has 70% of the world's coltan, and more than 30% of the world's diamond reserves., mostly in the form of small, industrial diamonds. The coltan is a major source of tantalum, which is used in the fabrication of electronic components in computers and mobile phones. In 2002, tin was discovered in the east of the country, but, to date, mining has been done on a small scale. Manono in Central DRC has a significant deposit of lithium and tin with tantalum and niobium and is being developed by an Australian company. Production is expected in 2023. Smuggling of the conflict minerals, coltan and cassiterite (ores of tantalum and tin, respectively), has helped fuel the war in the Eastern Congo. Today's larger mining companies are making changes and adhering to global demand for ESG ( Environmental, Social and Governance) and IRMA (Initiative for Responsible Mining Assurance). One such globally recognised certification is the 3T iTSCi, the only widely implemented and accepted mineral traceability and due diligence system in the region for the 3T minerals – Tin, Tantalum and Tungsten, an internationally recognised certification for responsible mining and traceability under the 2010 Dodd-Frank Act. Today four central African countries including the Democratic Republic of Congo (DRC) provides legitimate and ethical 3T minerals. ITSCI is the only industry initiative with standards 100% aligned with the OECD Guidance. Much has been done in the last 15 years, providing artisanal |
For a long period of time, Mobutu was the sole leader of the Executive Council. He eventually would appoint First State Commissioners (known elsewhere as prime ministers) with largely coordinating powers and very little executive power. The last "First State Commissioner" was Kengo Wa Dondo. The Legislative Council: essentially the rubber-stamp parliament, it was made up of People Commissioners (known elsewhere as MPs), who were sometimes elected, as individual members of the MPR, and always on the party platform. The Supreme Court: As the judiciary, this court was seemingly the only independent branch of government, but in effect it was subordinate to a Judicial Council over which the regime had a very strong influence. Every corporation, whether financial or union, as well as every division of the administration, was set up as branches of the party. CEOs, union leaders, and division directors were each sworn-in as section presidents of the party. Every aspect of life was regulated to some degree by the party, and the will of its founding-president, Mobutu Sese Seko. Most of the petty aspects of the regime disappeared after 1990 with the beginning of the democratic transition. Democratization would prove to be fairly short-lived, as Mobutu's power plays dragged it in length until ultimately 1997, when forces led by Laurent Kabila eventually successfully toppled the regime, after a 9-month-long military campaign. The Kabilas' governments and war The government of former president Mobutu Sese Seko was toppled by a rebellion led by Laurent Kabila in May 1997, with the support of Rwanda and Uganda. They were later to turn against Kabila and backed a rebellion against him in August 1998. Troops from Zimbabwe, Angola, Namibia, Chad, and Sudan intervened to support the Kinshasa regime. A cease-fire was signed on 10 July 1999 by the DROC, Zimbabwe, Angola, Uganda, Namibia, Rwanda, and Congolese armed rebel groups, but fighting continued. Under Laurent Kabila's regime, all executive, legislative, and military powers were first vested in the President, Laurent-Désiré Kabila. The judiciary was independent, with the president having the power to dismiss or appoint. The president was first head of a 26-member cabinet dominated by the Alliance of Democratic Forces for the Liberation of Congo (ADFL). Towards the end of the 90s, Laurent Kabila created and appointed a Transitional Parliament, with a seat in the buildings of the former Katanga Parliament, in the southern town of Lubumbashi, in a move to unite the country, and to legitimate his regime. Kabila was assassinated on 16 January 2001 and his son Joseph Kabila was named head of state ten days later. The younger Kabila continued with his father's Transitional Parliament, but overhauled his entire cabinet, replacing it with a group of technocrats, with the stated aim of putting the country back on the track of development, and coming to a decisive end of the Second Congo War. In October 2002, the new president was successful in getting occupying Rwandan forces to withdraw from eastern Congo; two months later, an agreement was signed by all remaining warring parties to end the fighting and set up a Transition Government, the make-up of which would allow representation for all negotiating parties. Two founding documents emerged from this: The Transition Constitution, and the Global and Inclusive Agreement, both of which describe and determine the make-up and organization of the Congolese institutions, until planned elections in July 2006, at which time the provisions of the new constitution, democratically approved by referendum in December 2005, will take full effect and that is how it happened. Under the Global and All-Inclusive Agreement, signed on 17 December 2002, in Pretoria, there was to be one President and four Vice-Presidents, one from the government, one from the Rally for Congolese Democracy, one from the MLC, and one from civil society. The position of Vice-President expired after the 2006 elections. After being for three years (2003–06) in the interregnum between two constitutions, | division directors were each sworn-in as section presidents of the party.

The position of Vice-President expired after the 2006 elections. After being for three years (2003–06) in the interregnum between two constitutions, the Democratic Republic of the Congo is now under the regime of the Constitution of the Third Republic. The constitution, adopted by referendum in 2005, and promulgated by President Joseph Kabila in February 2006, establishes a decentralized semi-presidential republic, with a separation of powers between the three branches of government - executive, legislative and judiciary, and a distribution of prerogatives between the central government and the provinces. In September 2016, violent protests were met with brutal force by the police and Republican Guard soldiers. Opposition groups claim 80 dead, including the Students' Union leader. From Monday 19 September Kinshasa residents, as well as residents elsewhere in Congo, where mostly confined to their homes. Police arrested anyone remotely connected to the opposition as well as innocent onlookers. Government propaganda, on television, and actions of covert government groups in the streets, acted against opposition as well as foreigners. The president's mandate was due to end on 19 December 2016, but no plans were made to elect a replacement at that time and this caused further protests. As of 8 August 2017 there are 54 political parties legally operating in the Congo. On 15 December 2018 US State Department announced it had decided to evacuate its employees’ family members from Democratic Republic of Congo just before the Congolese elections to choose a successor to President Joseph Kabila. Félix Tshisekedi Presidency (2019-) On 30 December 2018 the presidential election to determine the successor to Kabila was held. On 10 January 2019, the electoral commission announced opposition candidate Félix Tshisekedi as the winner of the vote. He was officially sworn in as President on 24 January 2019. In the ceremony of taking of the office Félix Tshisekedi appointed Vital Kamerhe as his chief of staff. In June 2020, chief of staff Vital Kamerhe was found guilty of embezzling public funds and he was sentenced to 20 years in prison. The political allies of former president Joseph Kabila, who stepped down in January 2019, maintained control of key ministries, the legislature, judiciary and security services. However, President Felix Tshisekedi succeeded to strengthen his hold on power. In a series of moves, he won over more legislators, gaining the support of almost 400 out of 500 members of the National Assembly. The pro-Kabila speakers of both houses of parliament were forced out. In April 2021, the new government was formed without the supporters of Kabila. President Felix Tshisekedi succeeded to oust the last remaining elements of his government who were loyal to former leader Joseph Kabila. Executive branch Since the July 2006 elections, the country is led by a semi-presidential, strongly-decentralized state. The executive at the central level, is divided between the President, and a Prime Minister appointed by him/her |

damaged the infrastructure, the so-called "national" route, used to get supplies to Bukavu from the seaport of Matadi, consisted of the following: Matadi to Kinshasa – rail Kinshasa to Kisangani – river boat Kisangani to Ubundu – rail Ubundu to Kindu – river boat Kindu to Kalemie – rail Kalemie to Kalundu (the lake port at Uvira) – boat on Lake Tanganyika Kalundu to Bukavu – road In other words, goods had to be loaded and unloaded eight times and the total journey would take many months. Many of the routes listed below are in poor condition and may be operating at only a fraction of their original capacity (if at all), despite recent attempts to make improvements. Up to 2006 the United Nations Joint Logistics Centre (UNJLC) had an operation in Congo to support humanitarian relief agencies working there, and its bulletins and maps about the transport situation are archived on ReliefWeb. The First and Second Congo Wars saw great destruction of transport infrastructure from which the country has not yet recovered. Many vehicles were destroyed or commandeered by militias, especially in the north and east of the country, and the fuel supply system was also badly affected. Consequently, outside of Kinshasa, Matadi and Lubumbashi, private and commercial road transport is almost non-existent and traffic is scarce even where roads are in good condition. The few vehicles in use outside these cities are run by the United Nations, aid agencies, the DRC government, and a few larger companies such as those in the mining and energy sectors. High-resolution satellite photos on the Internet show large cities such as Bukavu, Butembo and Kikwit virtually devoid of traffic, compared to similar photos of towns in neighbouring countries. Air transport is the only effective means of moving between many places within the country. The Congolese government, the United Nations, aid organisations and large companies use air rather than ground transport to move personnel and freight. The UN operates a large fleet of aircraft and helicopters, and compared to other African countries the DRC has a large number of small domestic airlines and air charter companies. The transport (and smuggling) of minerals with a high value for weight is also carried out by air, and in the east, some stretches of paved road isolated by destroyed bridges or impassable sections have been turned into airstrips. For the ordinary citizen though, especially in rural areas, often the only options are to cycle, walk or go by dugout canoe. Some parts of the DRC are more accessible from neighbouring countries than from Kinshasa. For example, Bukavu itself and Goma and other north-eastern towns are linked by paved road from the DRC border to the Kenyan port of Mombasa, and most goods for these cities have been brought via this route in recent years. Similarly, Lubumbashi and the rest of Katanga Province is linked to Zambia, through which the paved highway and rail networks of Southern Africa can be accessed. Such links through neighbouring countries are generally more important for the east and south-east of the country, and are more heavily used, than surface links to the capital. Major infrastructure programs In 2007 China agreed to lend the DRC US$5bn for two major transport infrastructure projects to link mineral-rich Katanga, specifically Lubumbashi, by rail to an ocean port (Matadi) and by road to the Kisangani river port, and to improve its links to the transport network of Southern Africa in Zambia. The two projects would also link the major parts of the country not served by water transport, and the main centres of the economy. Loan repayments will be from concessions for raw materials which China desperately needs: copper, cobalt, gold and nickel, as well as by toll revenues from the road and railway. In the face of reluctance by the international business community to invest in DRC, this represents a revitalisation of DRC's infrastructure much needed by its government. The China Railway Seventh Group Co. Ltd will be in charge of the contract, under signed by the China Railway Engineering Corporation, with construction to be started from June 2008. Railways Highways The Democratic Republic of the Congo has fewer all-weather paved highways than any country of its population and size in Africa — a total of 2250 km, of which only 1226 km is in good condition (see below). To put this in perspective, the road distance across the country in any direction is more than 2500 km (e.g. Matadi to Lubumbashi, 2700 km by road). The figure of 2250 km converts to 35 km of paved road per 1,000,000 of population. Comparative figures for Zambia and Botswana are 721 km and 3427 km respectively. Categories The road network is theoretically divided into four categories (national roads, priority regional roads, secondary regional roads and local roads), however, the United Nations Joint Logistics Centre (UNJLC) reports that this classification is of little practical use because some roads simply do not exist. For example, National Road 9 is not operational and cannot be detected by remote sensing methods. The two principal highways are: National Road No. 1 connecting the Atlantic seaports with Kinshasa and southeast Katanga, the | tugs pushing several barges lashed together, and for the hundreds of passengers and traders these function like small floating towns. Rather than mooring at riverside communities along the route, traders come out by canoe and small boat alongside the river barges and transfer goods on the move. Most waterway routes do not operate to regular schedules. It is common for an operator to moor a barge at a riverside town and collect freight and passengers over a period of weeks before hiring a river tug to tow or push the barge to its destination. Description of Inland Waterways in the Congo from the UN Joint Logistics Centre International links via inland waterways Kinshasa is linked to Brazzaville (Republic of the Congo) by regular boat and ferry services 3.5 km across the Congo River. Kinshasa and other river ports via the Ubangui River to Bangui (Central African Republic). Goma and Bukavu on Lake Kivu to Gisenyi, Kibuye and Cyangugu in Rwanda. Kalemie, Kulundu-Uvira and Moba on Lake Tanganyika to Kigoma (Tanzania), Bujumbura (Burundi) and Mpulungu (Zambia). Kasenga and Pweto on the Luapula River-Lake Mweru system to Nchelenge, Kashikishi and Kashiba in Zambia. Lake Albert: two small ports on the DRC side, Kisenye near Bunia and Mahadi-Port in the north can link to Ugandan ports at Butiaba and Pakwach (served by Uganda Railways) on the Albert Nile, which is navigable as far as Nimule in southern Sudan. Water transport is conducted principally in small craft, and commercial water transport is relatively absent. Lake Edward: located within national parks, settlements are small, water transport is conducted principally in small craft, commercial water transport is absent. Domestic links via inland waterways The middle Congo River and its tributaries from the east are the principal domestic waterways in the DRC. The two principal river routes are: Kinshasa to Mbandaka and Kisangani on the River Congo Kinshasa to Ilebo on the Kasai River See the diagrammatic transport map above for other river waterways. The most-used domestic lake waterways are: Kalemie to Kalundu-Uvira on Lake Tanganyika Bukavu to Goma on Lake Kivu Fimi River to Inongo on Lake Mai-Ndombe Irebu on the Congo to Bikoro on Lake Tumba Kasenga to Pweto on the Luapula-Mweru system Kisenye to Mahadi-Port on Lake Albert. Most large Congo river ferry boats were destroyed during the civil war. Only smaller boats are running and they are irregular.

As of 2016 the country does not have an international passenger airline and relies on foreign-based airlines for international connections. Congo Airways provides domestic flights and are based at Kinshasa's N'djili Airport which serves as the country's main international airport. Lubumbashi International Airport in the country's south-east is also serviced by several international airlines.

Province would form the second region, and Maniema and Kasai-Oriental provinces the third. Katanga and Équateur would fall under the fourth and fifth regions, respectively, while Kasai-Occidental and Bandundu would form the sixth region. Kinshasa and Bas-Congo would form the seventh and eighth regions, respectively. In November 1999 the Government attempted to form a 20,000-strong paramilitary force designated the People's Defence Forces. This force was intended to support the FAC and national police but never became effective. 1999–present The Lusaka Ceasefire Agreement was not successful in ending the war, and fighting resumed in September 1999. The FAC's performance continued to be poor and both the major offensives the Government launched in 2000 ended in costly defeats. President Kabila's mismanagement was an important factor behind the FAC's poor performance, with soldiers frequently going unpaid and unfed while the Government purchased advanced weaponry which could not be operated or maintained. The defeats in 2000 are believed to have been the cause of President Kabila's assassination in January 2001. Following the assassination, Joseph Kabila assumed the presidency and was eventually successful in negotiating an end to the war in 2002–2003. The December 2002 Global and All-Inclusive Agreement devoted Chapter VII to the armed forces. It stipulated that the armed forces chief of staff, and the chiefs of the army, air force, and navy were not to come from the same warring faction. The new "national, restructured and integrated" army would be made up from Kabila's government forces (the FAC), the RCD, and the MLC. Also stipulated in VII(b) was that the RCD-N, RCD-ML, and the Mai-Mai would become part of the new armed forces. An intermediate mechanism for physical identification of the soldiers, and their origin, date of enrolment, and unit was also called for (VII(c)). It also provided for the creation of a Conseil Superieur de la Defense (Superior Defence Council) which would declare states of siege or war and give advice on security sector reform, disarmament/demobilization, and national defence policy. A decision on which factions were to name chiefs of staff and military regional commanders was announced on 19 August 2003 as the first move in military reform, superimposed on top of the various groups of fighters, government and former rebels. Kabila was able to name the armed forces chief of staff, Lieutenant General Liwanga Mata, who previously served as navy chief of staff under Laurent Kabila. Kabila was able to name the air force commander (John Numbi), the RCD-Goma received the Land Force commander's position (Sylvain Buki) and the MLC the navy (Dieudonne Amuli Bahigwa). Three military regional commanders were nominated by the former Kinshasa government, two commanders each by the RCD-Goma and the MLC, and one region commander each by the RCD-K/ML and RCD-N. However these appointments were announced for Kabila's Forces armées congolaises (FAC), not the later FARDC. Another report however says that the military region commanders were only nominated in January 2004, and that the troop deployment on the ground did not change substantially until the year afterward. On 24 January 2004, a decree created the Structure Militaire d'Intégration (SMI, Military Integration Structure). Together with the SMI, CONADER also was designated to manage the combined tronc commun DDR element and military reform programme. The first post-Sun City military law appears to have been passed on 12 November 2004, which formally created the new national Forces Armées de la République Démocratique du Congo (FARDC). Included in this law was article 45, which recognised the incorporation of a number of armed groups into the FARDC, including the former government army Forces Armées Congolaises (FAC), ex-FAZ personnel also known as former President Mobutu's 'les tigres', the RCD-Goma, RCD-ML, RCD-N, MLC, the Mai-Mai, as well as other government-determined military and paramilitary groups. Turner writes that the two most prominent opponents of military integration (brassage) were Colonel Jules Mutebusi, a Munyamulenge from South Kivu, and Laurent Nkunda, a Rwandaphone Tutsi who Turner says was allegedly from Rutshuru in North Kivu. In May–June 2004 Mutebusi led a revolt against his superiors from Kinshasa in South Kivu. Nkunda began his long series of revolts against central authority by helping Mutebusi in May–June 2004. In November 2004 a Rwandan government force entered North Kivu to attack the FDLR, and, it seems, reinforced and resupplied RCD-Goma (ANC) at the same time. Mutebutsi and Nkunda were seemingly supported by both the Rwandan government, the FARDC regional commander, General Obed Rwisbasira, and the RCD-Goma governor of North Kivu, Eugene Serufuli. Neither government figure did anything to prevent Nkunda's march south to Bukavu with his military force. In mid-December, civilians at Kanyabayonga, Buramba, and Nyabiondo in North Kivu were killed, tortured, and raped, seemingly deliberately targeted on ethic grounds (the victims came almost exclusively from the Hunde and Nande ethnic groups). Kabila despatched 10,000 government troops to the east in response, launching an operation 11 December that was called "Operation Bima". Its only major success was the capture of Walikale from RCD-Goma (ANC) troops. There was another major personnel reshuffle on 12 June 2007. FARDC chief General Kisempia Sungilanga Lombe was replaced with General Dieudonne Kayembe Mbandankulu. General Gabriel Amisi Kumba retained his post as Land Forces commander. John Numbi, a trusted member of Kabila's inner circle, was shifted from air force commander to Police Inspector General. U.S. diplomats reported that the former Naval Forces Commander Maj. General Amuli Bahigua (ex-MLC) became the FARDC's Chief of Operations; former FARDC Intelligence Chief General Didier Etumba (ex-FAC) was promoted to vice admiral and appointed Commander of Naval Forces; Maj. General Rigobert Massamba (ex-FAC), a former commander of the Kitona air base, was appointed as Air Forces Commander; and Brig. General Jean-Claude Kifwa, commander of the Republican Guard, was appointed as a regional military commander. Due to significant delays in the DDR and integration process, of the eighteen brigades, only seventeen have been declared operational, over two and a half years after the initial target date. Responding to the situation, the Congolese Minister of Defence presented a new defence reform master plan to the international community in February 2008. Essentially the three force tiers all had their readiness dates pushed back: the first, territorial forces, to 2008–12, the mobile force to 2008–10, and the main defence force to 2015. Much of the east of the country remains insecure, however. In the far northeast this is due primarily to the Ituri conflict. In the area around Lake Kivu, primarily in North Kivu, fighting continues among the Democratic Forces for the Liberation of Rwanda and between the government FARDC and Laurent Nkunda's troops, with all groups greatly exacerbating the issues of internal refugees in the area of Goma, the consequent food shortages, and loss of infrastructure from the years of conflict. In 2009, several United Nations officials stated that the army is a major problem, largely due to corruption that results in food and pay meant for soldiers being diverted and a military structure top-heavy with colonels, many of whom are former warlords. In a 2009 report itemizing FARDC abuses, Human Rights Watch urged the UN to stop supporting government offensives against eastern rebels until the abuses ceased. Caty Clement wrote in 2009: "One of the most notable [FARDC corruption] schemes was known as 'Opération Retour' (Operation Return). Senior officers ordered the soldiers' pay to be sent from Kinshasa to the commanders in the field, who took their cut and returned the remainder to their commander in Kinshasa instead of paying the soldiers. To ensure that foot soldiers would be paid their due, in late 2005, EUSEC suggested separating the chain of command from the chain of payment. The former remained within Congolese hands, while the EU mission delivered salaries directly to the newly 'integrated' brigades. Although efficient in the short term, this solution raises the question of sustainability and ownership in the long term. Once soldiers' pay could no longer be siphoned off via 'Opération Retour', however, two other budgetary lines, the 'fonds de ménage' and logistical support to the brigades, were soon diverted." In 2010, thirty FARDC officers were given scholarships to study in Russian military academies. This is part of a greater effort by Russia to help improve the FARDC. A new military attaché and other advisers from Russia visited the DRC. On 22 November 2012, Gabriel Amisi Kumba was suspended from his position in the Forces Terrestres by president Joseph Kabila due to an inquiry into his alleged role in the sale of arms to various rebel groups in the eastern part of the country, which may have implicated the rebel group M23. In December 2012 it was reported that members of Army units in the north east of the country are often not paid due to corruption, and these units rarely made against villages by the Lord's Resistance Army. The FARDC deployed 850 soldiers and 150 PNC police officers as part of an international force in the Central African Republic, which the DRC borders to the north. The country had been in a state of civil war since 2012, when the president was ousted by rebel groups. The DRC was urged by French president François Hollande to keep its troops in CAR. In July 2014, the Congolese army carried out a joint operation with UN troops in the Masisi and Walikale territories of the North Kivu province. In the process, they liberated over 20 villages and a mine from the control of two rebel groups, the Mai Mai Cheka and the Alliance for the Sovereign and Patriotic Congo. The UN published a report in October 2017 announcing that the FARDC no longer employed child soldiers but was still listed under militaries that committed sexual violations against children. Troops operating with MONUSCO in North Kivu were attacked by likely rebels from the Allied Democratic Forces on 8 December 2017. After a protracted firefight the troops suffered 5 dead along with 14 dead among the UN force. Current organisation The President Félix Tshisekedi is the Commander-in-Chief of the Armed Forces. The Minister of Defence, formally Ministers of Defence and Veterans (Ancien Combattants) is Crispin Atama Tabe, who succeeded former minister Aimé Ngoy Mukena. The Colonel Tshatshi Military Camp in the Kinshasa suburb of Ngaliema hosts the defence department and the Chiefs of Staff central command headquarters of the FARDC. Jane's data from 2002 appears inaccurate; there is at least one ammunition plant in Katanga. Below the Chief of Staff, the current organisation of the FARDC is not fully clear. There is known to be a Military Intelligence branch – Service du Renseignement militaire (SRM), the former DEMIAP. The FARDC is known to be broken up into the Land Forces (Forces Terrestres), Navy and Air Force. The Land Forces are distributed around ten military regions, up from the previous eight, following the ten provinces of the country. There is also a training command, the Groupement des Écoles Supérieurs Militaires (GESM) or Group of Higher Military Schools, which, in January 2010, was under the command of Major General Marcellin Lukama. The Navy and Air Forces are composed of various groupments (see below). There is also a central logistics base. It should be made clear also that Joseph Kabila does not trust the military; the Republican Guard is the only component he trusts. Major General John Numbi, former Air Force chief, now inspector general of police, ran a parallel chain of command in the east to direct the 2009 Eastern Congo offensive, Operation Umoja Wetu; the regular chain of command was by-passed. Previously Numbi negotiated the agreement to carry out the mixage process with Laurent Nkunda. Commenting on a proposed vote of no confidence in the Minister of Defence in September 2012, Baoudin Amba Wetshi of lecongolais.cd described Ntolo as a "scapegoat". Wetshi said that all key military and security questions were handled in total secrecy by the President and other civil and military personalities trusted by him, such as John Numbi, Gabriel Amisi Kumba ('Tango Four'), Delphin Kahimbi, and others such as Kalev Mutond and Pierre Lumbi Okongo.

In addition to armed forces chiefs of staff, in 1966 Lieutenant Colonel Ferdinand Malila was listed as Army Chief of Staff. Command structure in January 2005 Virtually all officers have now changed positions, but this list gives an outline of the structure in January 2005. Despite the planned subdivision of the country into more numerous provinces, the actual splitting of the former provinces has not taken place. FARDC chief of staff: Major General Sungilanga Kisempia (PPRD) FARDC land forces chief of staff: General Sylvain Buki (RCD-G). Major General Gabriel Amisi Kumba appears to have been appointed to the position in August 2006, and retained this position during the personnel reshuffle of 12 June 2007. In November 2012 he was succeeded by François Olenga. FARDC navy chief of staff: General Major Dieudonne Amuli Bahigwa (MLC) (Commander of the Kimia II operation in 2009) FARDC air force chief of staff: Brigadier General Jean Bitanihirwa Kamara (MLC).

This grouping was "an almost exclusively Banyamulenge brigade under the direct command of the 10th Military Region, [which] consider[ed] General Masunzu as its leader." Updates to command structure in 2014 In September 2014, President Kabila reshuffled the command structure and in addition to military regions created three new 'defence zones' which would be subordinated directly to the general staff. The defence zones essentially created a new layer between the general staff and the provincial commanders. The military regions themselves were reorganised and do not correspond with the ones that existed prior to the reshuffle. New commanders of branches were also appointed: A Congolese military analyst based in Brussels, Jean-Jacques Wondo, provided an outline of the updated command structure of the FARDC following the shake up of the high command: Chief of General Staff: Army Gen.

Jean-Luc Yav Chief of logistics: Brig. Gen. Kalala Kilumba Land forces Circa 2008–09, the land forces were made up of about 14 integrated brigades of fighters from all the former warring factions who went through a brassage integration process (see next paragraph) and a limited number of non-integrated brigades that remain solely made up of single factions (the Congolese Rally for Democracy (RCD)'s Armée national congolaise, the ex-government former Congolese Armed Forces (FAC), the ex-RCD KML, the ex-Movement for the Liberation of Congo, the armed groups of the Ituri conflict (the Mouvement des Révolutionnaires Congolais (MRC), Forces de Résistance Patriotique d'Ituri (FRPI), and the Front Nationaliste Intégrationniste (FNI)), and the Mai-Mai). It appears that about the same time that Presidential Decree 03/042 of 18 December 2003 established the National Commission for Demobilisation and Reinsertion (CONADER), "..all ex-combatants were officially declared as FARDC soldiers and the then FARDC brigades [were to] rest deployed until the order to leave for brassage" [the military integration process]. The reform plan adopted in 2005 envisaged the formation of eighteen integrated brigades through the military integration process as its first of three stages. The process consisted firstly of regroupment, where fighters are disarmed. Then they were sent to orientation centres, run by CONADER, where fighters took the choice of either returning to civilian society or remaining in the armed forces. Combatants who chose demobilisation received an initial cash payment of US$110. Those who chose to stay within the FARDC were then transferred to one of six integration centres for a 45-day training course, which aimed to build integrated formations out of factional fighters previously heavily divided along ethnic, political and regional lines. The centres were spread out around the country at Kitona, Kamina, Kisangani, Rumangabo and Nyaleke (within the Virunga National Park) in Nord-Kivu, and Luberizi (on the border with Burundi) in South Kivu. The process suffered severe difficulties due to construction delays, administration errors, and the amount of travel former combatants have to do, as the three stages' centres are widely separated. There were three sequential buildup stages in the 2005 plan. Following the first 18 integrated brigades, the second goal was the formation of a ready reaction force of two to three brigades, and finally, by 2010, when MONUC was hoped to have withdrawn, the creation of a Main Defence Force of three divisions. In February 2008, then Defence Minister Chikez Diemu described the reform plan at the time as: "The short term, 2008–2010, will see the setting in place of a Rapid Reaction Force; the medium term, 2008–2015, with a Covering Force; and finally the long term, 2015–2020, with a Principal Defence Force." Diemu added that the reform plan rests on a programme of synergy based on the four pillars of dissuasion, production, reconstruction and excellence. "The Rapid Reaction Force is expected to focus on dissuasion, through a Rapid Reaction Force of 12 battalions, capable of aiding MONUC to secure the east of the country and to realise constitutional missions." Amid the other difficulties in building new armed forces for the DRC, in early 2007 the integration and training process was distorted as the DRC government under Kabila attempted to use it to gain more control over the dissident general Laurent Nkunda. A hastily negotiated verbal agreement in Rwanda saw three government FAC brigades integrated with Nkunda's former ANC 81st and 83rd Brigades in what was called mixage. Mixage brought multiple factions into composite brigades, but without the 45-day retraining provided by brassage, and it seems that actually, the process was limited to exchanging battalions between the FAC and Nkunda brigades in North Kivu, without further integration. Due to Nkunda's troops having greater cohesion, Nkunda effectively gained control of all five brigades, which was not the intention of the DRC central government. However, after Nkunda used the mixage brigades to fight the FDLR, strains arose between the FARDC and Nkunda-loyalist troops within the brigades and they fell apart in the last days of August 2007. The International Crisis Group says that "by 30 August [2007] Nkunda's troops had left the mixed brigades and controlled a large part of the Masisi and Rutshuru territories" (of North Kivu). Both formally integrated brigades and the non-integrated units continue to conduct arbitrary arrests, rapes, robbery, and other crimes and these human rights violations are "regularly" committed by both officers and members of the rank and file. Members of the Army also often strike deals to gain access to resources with the militias they are meant to be fighting. The various brigades and other formations and units number at least 100,000 troops. The status of these brigades has been described as "pretty chaotic." A 2007 disarmament and repatriation study said "army units that have not yet gone through the process of brassage are usually much smaller than what they ought to be. Some non-integrated brigades have only 500 men (and are thus nothing more than a small battalion) whereas some battalions may not even have the size of a normal company (over a 100 men)." A number of outside donor countries are also carrying out separate training programmes for various parts of the Forces du Terrestres (Land Forces). The People's Republic of China has trained Congolese troops at Kamina in Katanga from at least 2004 to 2009, and the Belgian government is training at least one "rapid reaction" battalion. When Kabila visited U.S. President George W. Bush in Washington D.C., he also asked the U.S. Government to train a battalion, and as a result, a private contractor, Protection Strategies Incorporated, started training a FARDC battalion at Camp Base, Kisangani, in February 2010. The company was supervised by United States Special Operations Command Africa. Three years later, the battalion broke and ran in the face of M23, raping women and young girls, looting, and carrying out arbitrary executions. The various international training programmes are not well integrated. Equipment Attempting to list the equipment available to the DRC's land forces is difficult; most figures are unreliable estimates based on known items delivered in the past. The figures below are from the IISS Military Balance 2014. Much of the Army's equipment is non-operational due to insufficient maintenance—in 2002 only 20 percent of the Army's armoured vehicles were estimated as being serviceable. Main Battle Tanks: 12–17 x Type 59 (dropped from 30 listed in 2007), 32 x T-55, 100 x T 72. Thirty T-55s and 100 T-72 were listed in 2007, thus little new information has reached the IISS in the intervening seven years. Light tanks: 10 PT-76; 30 Type 62 (serviceability in doubt). "40+" Type 62s were listed by the Military Balance in 2007. Reconnaissance vehicles: Up to 17 Panhard AML-60, 14 AML-90 armoured cars, 19 EE-9 Cascavel; 2 RAM-V-2. Infantry Fighting Vehicles: 20 BMP-1 (number reported unchanged since 2007). Armoured Personnel Carriers: IISS reports tracked vehicles include 3 BTR-50, 6 MT-LB, wheeled vehicles including 30-70 BTR-60; 58 Panhard M3 (serviceability in doubt), 7 TH 390 Fahd. Artillery: 16 2S1 and 2S3 self-propelled; 119 towed field guns, including 77 122 mm howitzer 2A18 130 mm D-30/M-1938/Type-60; 57 MRL, including 24 Type 81; 528+ mortars, 81 mm, 82 mm, 107 mm, 120 mm. In addition to these 2014 figures, in March 2010, it was reported that the DRC's land forces had ordered US$80 million worth of military equipment from Ukraine which included 20 T-72 main battle tanks, 100 trucks and various small arms. Tanks have been used in the Kivus in the 2005–09 period. In February 2014, Ukraine revealed that it had achieved the first export order for the T-64 tank to the DRC Land Forces for 50 T-64BV-1s. In June 2015 it was reported that Georgia had sold 12 of its Didgori-2 to the DRC for $4 million. The vehicles were specifically designed for reconnaissance and special operations. Two of the vehicles are a recently developed conversion to serve for medical field evacuation. The United Nations confirmed in 2011, both from sources in the Congolese military and from officials of the Commission nationale de contrôle des armes légères et de petit calibre et de réduction de la violence armée, that the ammunition plant called Afridex in Likasi, Katanga Province, manufactures ammunition for small arms and light weapons. Republican Guard In addition to the other land forces, President Joseph Kabila also has a Republican Guard presidential force (Garde Républicaine or GR), formerly known as the Special Presidential Security Group (GSSP). FARDC military officials state that the Garde Républicaine is not the responsibility of FARDC, but of the Head of State. Apart from Article 140 of the Law on the Army and Defence, no legal stipulation on the DRC's Armed Forces makes provision for the GR as a distinct unit within the national army. In February 2005 President Joseph Kabila passed a decree which appointed the GR's commanding officer and "repealed any previous provisions contrary" to that decree. The GR, more than 10,000 strong (the ICG said 10,000 to 15,000 in January 2007), has better working conditions and is paid regularly, but still commits rapes and robberies in the vicinity of its bases. In an effort to extend his personal control across the country, Joseph Kabila has deployed the GR at key airports, ostensibly in preparation for an impending presidential visit. there were Guards deployed in the central prison of Kinshasa, N'djili | governor of North Kivu, Eugene Serufuli. Neither government figure did anything to prevent Nkunda's march south to Bukavu with his military force. In mid-December, civilians at Kanyabayonga, Buramba, and Nyabiondo in North Kivu were killed, tortured, and raped, seemingly deliberately targeted on ethic grounds (the victims came almost exclusively from the Hunde and Nande ethnic groups). Kabila despatched 10,000 government troops to the east in response, launching an operation 11 December that was called "Operation Bima". Its only major success was the capture of Walikale from RCD-Goma (ANC) troops. There was another major personnel reshuffle on 12 June 2007. FARDC chief General Kisempia Sungilanga Lombe was replaced with General Dieudonne Kayembe Mbandankulu. General Gabriel Amisi Kumba retained his post as Land Forces commander. John Numbi, a trusted member of Kabila's inner circle, was shifted from air force commander to Police Inspector General. U.S. diplomats reported that the former Naval Forces Commander Maj. General Amuli Bahigua (ex-MLC) became the FARDC's Chief of Operations; former FARDC Intelligence Chief General Didier Etumba (ex-FAC) was promoted to vice admiral and appointed Commander of Naval Forces; Maj. General Rigobert Massamba (ex-FAC), a former commander of the Kitona air base, was appointed as Air Forces Commander; and Brig. General Jean-Claude Kifwa, commander of the Republican Guard, was appointed as a regional military commander. Due to significant delays in the DDR and integration process, of the eighteen brigades, only seventeen have been declared operational, over two and a half years after the initial target date. Responding to the situation, the Congolese Minister of Defence presented a new defence reform master plan to the international community in February 2008. Essentially the three force tiers all had their readiness dates pushed back: the first, territorial forces, to 2008–12, the mobile force to 2008–10, and the main defence force to 2015. Much of the east of the country remains insecure, however. In the far northeast this is due primarily to the Ituri conflict. In the area around Lake Kivu, primarily in North Kivu, fighting continues among the Democratic Forces for the Liberation of Rwanda and between the government FARDC and Laurent Nkunda's troops, with all groups greatly exacerbating the issues of internal refugees in the area of Goma, the consequent food shortages, and loss of infrastructure from the years of conflict. In 2009, several United Nations officials stated that the army is a major problem, largely due to corruption that results in food and pay meant for soldiers being diverted and a military structure top-heavy with colonels, many of whom are former warlords. In a 2009 report itemizing FARDC abuses, Human Rights Watch urged the UN to stop supporting government offensives against eastern rebels until the abuses ceased. Caty Clement wrote in 2009: "One of the most notable [FARDC corruption] schemes was known as 'Opération Retour' (Operation Return). Senior officers ordered the soldiers' pay to be sent from Kinshasa to the commanders in the field, who took their cut and returned the remainder to their commander in Kinshasa instead of paying the soldiers. To ensure that foot soldiers would be paid their due, in late 2005, EUSEC suggested separating the chain of command from the chain of payment. The former remained within Congolese hands, while the EU mission delivered salaries directly to the newly 'integrated' brigades. Although efficient in the short term, this solution raises the question of sustainability and ownership in the long term. Once soldiers' pay could no longer be siphoned off via 'Opération Retour', however, two other budgetary lines, the 'fonds de ménage' and logistical support to the brigades, were soon diverted." In 2010, thirty FARDC officers were given scholarships to study in Russian military academies. This is part of a greater effort by Russia to help improve the FARDC. A new military attaché and other advisers from Russia visited the DRC. On 22 November 2012, Gabriel Amisi Kumba was suspended from his position in the Forces Terrestres by president Joseph Kabila due to an inquiry into his alleged role in the sale of arms to various rebel groups in the eastern part of the country, which may have implicated the rebel group M23. In December 2012 it was reported that members of Army units in the north east of the country are often not paid due to corruption, and these units rarely made against villages by the Lord's Resistance Army. The FARDC deployed 850 soldiers and 150 PNC police officers as part of an international force in the Central African Republic, which the DRC borders to the north. The country had been in a state of civil war since 2012, when the president was ousted by rebel groups. The DRC was urged by French president François Hollande to keep its troops in CAR. In July 2014, the Congolese army carried out a joint operation with UN troops in the Masisi and Walikale territories of the North Kivu province. In the process, they liberated over 20 villages and a mine from the control of two rebel groups, the Mai Mai Cheka and the Alliance for the Sovereign and Patriotic Congo. The UN published a report in October 2017 announcing that the FARDC no longer employed child soldiers but was still listed under militaries that committed sexual violations against children. Troops operating with MONUSCO in North Kivu were attacked by likely rebels from the Allied Democratic Forces on 8 December 2017. After a protracted firefight the troops suffered 5 dead along with 14 dead among the UN force. Current organisation The President Félix Tshisekedi is the Commander-in-Chief of the Armed Forces. The Minister of Defence, formally Ministers of Defence and Veterans (Ancien Combattants) is Crispin Atama Tabe, who succeeded former minister Aimé Ngoy Mukena. The Colonel Tshatshi Military Camp in the Kinshasa suburb of Ngaliema hosts the defence department and the Chiefs of Staff central command headquarters of the FARDC. Jane's data from 2002 appears inaccurate; there is at least one ammunition plant in Katanga. Below the Chief of Staff, the current organisation of the FARDC is not fully clear. There is known to be a Military Intelligence branch – Service du Renseignement militaire (SRM), the former DEMIAP. The FARDC is known to be broken up into the Land Forces (Forces Terrestres), Navy and Air Force. The Land Forces are distributed around ten military regions, up from the previous eight, following the ten provinces of the country. There is also a training command, the Groupement des Écoles Supérieurs Militaires (GESM) or Group of Higher Military Schools, which, in January 2010, was under the command of Major General Marcellin Lukama. The Navy and Air Forces are composed of various groupments (see below). There is also a central logistics base. It should be made clear also that Joseph Kabila does not trust the military; the Republican Guard is the only component he trusts. Major General John Numbi, former Air Force chief, now inspector general of police, ran a parallel chain of command in the east to direct the 2009 Eastern Congo offensive, Operation Umoja Wetu; the regular chain of command was by-passed. Previously Numbi negotiated the agreement to carry out the mixage process with Laurent Nkunda. Commenting on a proposed vote of no confidence in the Minister of Defence in September 2012, Baoudin Amba Wetshi of lecongolais.cd described Ntolo as a "scapegoat". Wetshi said that all key military and security questions were handled in total secrecy by the President and other civil and military personalities trusted by him, such as John Numbi, Gabriel Amisi Kumba ('Tango Four'), Delphin Kahimbi, and others such as Kalev Mutond and Pierre Lumbi Okongo.

In addition to armed forces chiefs of staff, in 1966 Lieutenant Colonel Ferdinand Malila was listed as Army Chief of Staff. Command structure in January 2005 Virtually all officers have now changed positions, but this list gives an outline of the structure in January 2005. Despite the planned subdivision of the country into more numerous provinces, the actual splitting of the former provinces has not taken place. FARDC chief of staff: Major General Sungilanga Kisempia (PPRD) FARDC land forces chief of staff: General Sylvain Buki (RCD-G). Major General Gabriel Amisi Kumba appears to have been appointed to the position in August 2006, and retained this position during the personnel reshuffle of 12 June 2007. In November 2012 he was succeeded by François Olenga. FARDC navy chief of staff: General Major Dieudonne Amuli Bahigwa (MLC) (Commander of the Kimia II operation in 2009) FARDC air force chief of staff: Brigadier General Jean Bitanihirwa Kamara (MLC).

This grouping was "an almost exclusively Banyamulenge brigade under the direct command of the 10th Military Region, [which] consider[ed] General Masunzu as its leader." Updates to command structure in 2014 In September 2014, President Kabila reshuffled the command structure and in addition to military regions created three new 'defence zones' which would be subordinated directly to the general staff. The defence zones essentially created a new layer between the general staff and the provincial commanders. The military regions themselves were reorganised and do not correspond with the ones that existed prior to the reshuffle. New commanders of branches were also appointed: A Congolese military analyst based in Brussels, Jean-Jacques Wondo, provided an outline of the updated command structure of the FARDC following the shake up of the high command: Chief of General Staff: Army Gen.

Jean-Pierre Bongwangela Chief of operations: Maj. Gen. Daniel Kashale Chief of intelligence: Maj. Gen. Delphin Kahimbi Kasabwe Chief of administration: Maj. Gen. Jean-Luc Yav Chief of logistics: Brig. Gen. Kalala Kilumba Land forces Circa 2008–09, the land forces were made up of about 14 integrated brigades of fighters from all the former warring factions who went through a brassage integration process (see next paragraph) and a limited number of non-integrated brigades that remain solely made up of single factions (the Congolese Rally for Democracy (RCD)'s Armée national congolaise, the ex-government former Congolese Armed Forces (FAC), the ex-RCD KML, the ex-Movement for the Liberation of Congo, the armed groups of the Ituri conflict (the Mouvement des Révolutionnaires Congolais (MRC), Forces de Résistance Patriotique d'Ituri (FRPI), and the Front Nationaliste Intégrationniste (FNI)), and the Mai-Mai). It appears that about the same time that Presidential Decree 03/042 of 18 December 2003 established the National Commission for Demobilisation and Reinsertion (CONADER), "..all ex-combatants were officially declared as FARDC soldiers and the then FARDC brigades [were to] rest deployed until the order to leave for brassage" [the military integration process]. The reform plan adopted in 2005 envisaged the formation of eighteen integrated brigades through the military integration process as its first of three stages. The process consisted firstly of regroupment, where fighters are disarmed. Then they were sent to orientation centres, run by CONADER, where fighters took the choice of either returning to civilian society or remaining in the armed forces. Combatants who chose demobilisation received an initial cash payment of US$110. Those who chose to stay within the FARDC were then transferred to one of six integration centres for a 45-day training course, which aimed to build integrated formations out of factional fighters previously heavily divided along ethnic, political and regional lines. The centres were spread out around the country at Kitona, Kamina, Kisangani, Rumangabo and Nyaleke (within the Virunga National Park) in Nord-Kivu, and Luberizi (on the border with Burundi) in South Kivu. The process suffered severe difficulties due to construction delays, administration errors, and the amount of travel former combatants have to do, as the three stages' centres are widely separated. There were three sequential buildup stages in the 2005 plan. Following the first 18 integrated brigades, the second goal was the formation of a ready reaction force of two to three brigades, and finally, by 2010, when MONUC was hoped to have withdrawn, the creation of a Main Defence Force of three divisions. In February 2008, then Defence Minister Chikez Diemu described the reform plan at the time as: "The short term, 2008–2010, will see the setting in place of a Rapid Reaction Force; the medium term, 2008–2015, with a Covering Force; and finally the long term, 2015–2020, with a Principal Defence Force." Diemu added that the reform plan rests on a programme of synergy based on the four pillars of dissuasion, production, reconstruction and excellence. "The Rapid Reaction Force is expected to focus on dissuasion, through a Rapid Reaction Force of 12 battalions, capable of aiding MONUC to secure the east of the country and to realise constitutional missions." Amid the other difficulties in building new armed forces for the DRC, in early 2007 the integration and training process was distorted as the DRC government under Kabila attempted to use it to gain more control over the dissident general Laurent Nkunda. A hastily negotiated verbal agreement in Rwanda saw three government FAC brigades integrated with Nkunda's former ANC 81st and 83rd Brigades in what was called mixage. Mixage brought multiple factions into composite brigades, but without the 45-day retraining provided by brassage, and it seems that actually, the process was limited to exchanging battalions between the FAC and Nkunda brigades in North Kivu, without further integration. Due to Nkunda's troops having greater cohesion, Nkunda effectively gained control of all five brigades, which was not the intention of the DRC central government. However, after Nkunda used the mixage brigades to fight the FDLR, strains arose between the FARDC and Nkunda-loyalist troops within the brigades and they fell apart in the last days of August 2007. The International Crisis Group says that "by 30 August [2007] Nkunda's troops had left the mixed brigades and controlled a large part of the Masisi and Rutshuru territories" (of North Kivu). Both formally integrated brigades and the non-integrated units continue to conduct arbitrary arrests, rapes, robbery, and other crimes and these human rights violations are "regularly" committed by both officers and members of the rank and file. Members of the Army also often strike deals to gain access to resources with the militias they are meant to be fighting. The various brigades and other formations and units number at least 100,000 troops. The status of these brigades has been described as "pretty chaotic." A 2007 disarmament and repatriation study said "army units that have not yet gone through the process of brassage are usually much smaller than what they ought to be. Some non-integrated brigades have only 500 men (and are thus nothing more than a small battalion) whereas some battalions may not even have the size of a normal company (over a 100 men)." A number of outside donor countries are also carrying out separate training programmes for various parts of the Forces du Terrestres (Land Forces). The People's Republic of China has trained Congolese troops at Kamina in Katanga from at least 2004 to 2009, and the Belgian government is training at least one "rapid reaction" battalion. When Kabila visited U.S. President George W.

Much of the Army's equipment is non-operational due to insufficient maintenance—in 2002 only 20 percent of the Army's armoured vehicles were estimated as being serviceable. Main Battle Tanks: 12–17 x Type 59 (dropped from 30 listed in 2007), 32 x T-55, 100 x T 72. Thirty T-55s and 100 T-72 were listed in 2007, thus little new information has reached the IISS in the intervening seven years. Light tanks: 10 PT-76; 30 Type 62 (serviceability in doubt). "40+" Type 62s were listed by the Military Balance in 2007. Reconnaissance vehicles: Up to 17 Panhard AML-60, 14 AML-90 armoured cars, 19 EE-9 Cascavel; 2 RAM-V-2. Infantry Fighting Vehicles: 20 BMP-1 (number reported unchanged since 2007). Armoured Personnel Carriers: IISS reports tracked vehicles include 3 BTR-50, 6 MT-LB, wheeled vehicles including 30-70 BTR-60; 58 Panhard M3 (serviceability in doubt), 7 TH 390 Fahd. Artillery: 16 2S1 and 2S3 self-propelled; 119 towed field guns, including 77 122 mm howitzer 2A18 130 mm D-30/M-1938/Type-60; 57 MRL, including 24 Type 81; 528+ mortars, 81 mm, 82 mm, 107 mm, 120 mm. In addition to these 2014 figures, in March 2010, it was reported that the DRC's land forces had ordered US$80 million worth of military equipment from Ukraine which included 20 T-72 main battle tanks, 100 trucks and various small arms. Tanks have been used in the Kivus in the 2005–09 period. In February 2014, Ukraine revealed that it had achieved the first export order for the T-64 tank to the DRC Land Forces for 50 T-64BV-1s. In June 2015 it was reported that Georgia had sold 12 of its Didgori-2 to the DRC for $4 million. The vehicles were specifically designed for reconnaissance and special operations. Two of the vehicles are a recently developed conversion to serve for medical field evacuation. The United Nations confirmed in 2011, both from sources in the Congolese military and from officials of the Commission nationale de contrôle des armes légères et de petit calibre et de réduction de la violence armée, that the ammunition plant called Afridex in Likasi, Katanga Province, manufactures ammunition for small arms and light weapons. Republican Guard In addition to the other land forces, President Joseph Kabila also has a Republican Guard presidential force (Garde Républicaine or GR), formerly known as the Special Presidential Security Group (GSSP). FARDC military officials state that the Garde Républicaine is not the responsibility of FARDC, but of the Head of State. Apart from Article 140 of the Law on the Army and Defence, no legal stipulation on the DRC's Armed Forces makes provision for the GR as a distinct unit within the national army. In February 2005 President Joseph Kabila passed a decree which appointed the GR's commanding officer and "repealed any previous provisions contrary" to that decree. The GR, more than 10,000 strong (the ICG said 10,000 to 15,000 in January 2007), has better working conditions and is paid regularly, but still commits rapes and robberies in the vicinity of its bases. In an effort to extend his personal control across the country, Joseph Kabila has deployed the GR at key airports, ostensibly in preparation for an impending presidential visit. there were Guards deployed in the central prison of Kinshasa, N'djili Airport, Bukavu, Kisangani, Kindu, Lubumbashi, Matadi, and Moanda, where they appear to answer to no local commander and have caused trouble with MONUC troops there. The GR is also supposed to undergo the integration process, but in January 2007, only one battalion had been announced as having been integrated. Formed at a brassage centre in the Kinshasa suburb of Kibomango, the battalion included 800 men, half from the former GSSP and half from the MLC and RCD Goma. Up until June 2016, the GR comprised three brigades, the 10th Brigade at Camp Tshatshi and the 11th at Camp Kimbembe, both in Kinshasa, and the 13th Brigade at Camp Simi Simi in Kisangani. It was reorganised on the basis of eight fighting regiments, the 14th Security and Honor Regiment, an artillery regiment, and a command brigade/regiment from that time. Other forces active in the country There are currently large numbers of United Nations troops stationed in the DRC. The United Nations Organization Stabilization Mission in the Democratic Republic of the Congo (MONUSCO) on 31 March 2017 had a strength of over 18,316 peacekeepers (including 16,215 military personnel) and is tasked with assisting Congolese authorities to maintain security. The UN and foreign military aid missions, the most prominent being EUSEC RD Congo, are attempting to assist the Congolese in rebuilding the armed forces, with major efforts being made in trying to assure regular payment of salaries to armed forces personnel and also in military justice. Retired Canadian Lieutenant General Marc Caron also served for a time as Security Sector Reform advisor to the head of MONUC. Groups of anti-Rwandan government rebels like the FDLR, and other foreign fighters remain inside the DRC. The FDLR which is the greatest concern, was some 6,000 strong, in July 2007. By late 2010 the FDLR's strength however was estimated at 2,500. The other groups are smaller: the Ugandan Lord's Resistance Army, the Ugandan rebel group the Allied Democratic Forces in the remote area of Mt Rwenzori, and the Burundian Parti pour la Libération du Peuple Hutu—Forces Nationales de Liberation (PALIPEHUTU-FNL). Finally there is a government paramilitary force, created in 1997 under President Laurent Kabila. The National Service is tasked with providing the army with food and with training the youth in a range of reconstruction and developmental activities. There is not much further information available, and no internet-accessible source details the relationship of the National Service to other armed forces bodies; it is not listed in the constitution. President Kabila, in one of the few comments available, says National Service will provide a gainful activity for street children. Obligatory civil service administered through the armed forces was also proposed under the Mobutu regime during the "radicalisation" programme of December 1974 – January 1975; the FAZ was opposed to the measure and the plan "took several months to die." Air Force All military aircraft in the DRC are operated by the Air Force. Jane's World Air Forces states that the Air Force has an estimated strength of 1,800 personnel and is organised into two Air Groups. These Groups command five wings and nine squadrons, of which not all are operational. 1 Air Group is located at Kinshasa and consists of Liaison Wing, Training Wing and Logistical Wing and has a strength of five squadrons. 2 Tactical Air Group is located at Kaminia and consists of Pursuit and Attack Wing and Tactical Transport Wing and has a strength of four squadrons. Foreign private military companies have reportedly been contracted to provide the DRC's aerial reconnaissance capability using small propeller aircraft fitted with sophisticated equipment. Jane's states that National Air Force of Angola fighter aircraft would be made available to defend Kinshasa if it came under attack. Like the other services, the Congolese Air Force is not capable of carrying out its responsibilities. Few of the Air Force's aircraft are currently flyable or capable of being restored to service and it is unclear whether the Air Force is capable of maintaining even unsophisticated aircraft. Moreover, Jane's states that the Air Force's Ecole de Pilotage is 'in near total disarray' though Belgium has offered to restart the Air Force's pilot training program. In 2018 the IISS estimated that the Air Force numbered 2250 (p457); the 2020 edition carried the same number, unchanged. Navy Before the downfall of Mobutu, a small navy operated on the Congo river. One of its installations was at the village of N'dangi near the presidential residence in Gbadolite. The port at N'dangi was the base for several patrol boats, helicopters and the presidential yacht. The 2002 edition of Jane's Sentinel described the Navy as being "in a state of near total disarray" and stated that it did not conduct any training or have operating procedures. The Navy shares the same discipline problems as the other services. It was initially placed under command of the MLC when the transition began, so the current situation is uncertain. The 2007 edition of Jane's Fighting Ships states that the Navy is organised into four commands, based at Matadi, near the coast; the capital Kinshasa, further up the Congo river; Kalemie, on Lake Tanganyika; and Goma, on Lake Kivu. The International Institute for Strategic Studies, in its 2007 edition of the Military Balance, confirms the bases listed in Jane's and adds a fifth base at Boma, a coastal city near Matadi. Various sources also refer to numbered Naval Regions. Operations of the 1st Naval Region have been reported in Kalemie, the 4th near the northern city of Mbandaka, and the 5th at Goma. The IISS lists the Navy at 1,000 personnel and a total of eight patrol craft, of which only one is operational, a Shanghai II Type 062 class gunboat designated "102". There are five other 062s as well as two Swiftships which are not currently operational, though some may be restored to service in the future. According to Jane's, the Navy also operates barges and small craft armed with machine guns. As of 2012, the Navy on paper consisted of about 6,700 personnel and up to 23 patrol craft. In reality there was probably around 1,000 service members, and only 8 of the boats were 50 ft in length or larger, the sole operational vessel being a Shanghai II Type 062 class gunboat. The service maintains bases in Kinshasa, Boma, Matadi, Boma, and on Lake Tanganyika. The IISS repeated the same 6,700 figure in 2018 (p457) and the 2020 edition carried the same number, unchanged.
