--We examined 381 pellets that yielded 1764 prey items for Gurney's Buzzards (Buteo poecilochrous) at a pre-Andean (3600 m elevation, non-breeding season) and a high-Andean plateau site (4500 m elevation, breeding season) of northernmost Chile. We compared mammalian prey in the diet with mammals trapped in the field. Gurney's Buzzards preyed extensively on invertebrates (57 and 72% of items), but considering the invertebrates' mall biomass, the buzzards likely relied on vertebrates (primarily on small mammals) as their staple prey. The number of small mammals in the diet versus that obtained in the field agreed better at the pre-Andean than at the high-Andean plateau site. Differences in diet between sites were apparently related to the seasons when the sampling occurred. Hfibitos alimentarios del aguilucho de la puna en la precordillera ndina y el altiplano del extremo norte de Chile EXTRACTO.--Examinamos 381 egagr6pilas que rindieron 1764 presas del aguilucho de la puna (Buteo poecilochrous) en un sitio precordillerano (3600 m altura, estaci6n o reproductiva) yen uno altipl•tnico (4500 m altura, estaci6n reproductiva) del extremo norte de Chile. Comparamos la composici6n de mamlferos en la dieta con aquella obtenida por trampeos de terreno. E1 aguilucho de la puna pred6 extensamente sobre invertebrados (entre 57 y 71% de la dieta, num•ricamente), pero considerando la pequefia biomasa de estos invertebrados, es m•ts probable que el aguilucho dependiera m•ts de los vertebrados (principalmente de los micromamiferos) como elementos estables de su dieta. La incidencia num•rica de micromamlferos en la dieta versus la obtenida en el terreno se correspondi6 mejor en el sitio precordillerano queen el altipl•tnico. Las diferencias entre las dietas en los distintos itios aparentemente se deben alas distintas estaciones del afio en que se hicieron las colectas. Gurney's, or Red-naped, Buzzard (Buteo poecilochrous), is a medium-sized (about 1000 g), high altitude buteo found along the Andean ranges from Colombia south to neighboring Chile, Argentina and Bolivia. In this extreme of its distribution, the Andean mountain ranges enclose a high-altitude plateau (> 4000 m elevation). Little information exists on Gurney's Buzzard, the most recent being a description of its food habits in the high-Andean plateau of northernmost Chile (Jim•nez and Jaksifi 1990). These authors reported breeding season diet based on a sample of 27 pellets and 45 prey remains found in a nest. Here we document both breeding and non-breeding season diets of Gurney's Buzzard at two physiognomically and altitudinally different sites. We also compare mammalian prey with trapping results to estimate whether this raptor takes its mammalian prey in proportion to their estimated field abundance. STUDY AREAS AND METHODS At the pre-Andean locality of Patapatane (3600 m elevation, 18'05'S 69'43'W, 110 km E of Arica, Chile) we collected 229 fresh pellets below a cliff on 12 May 1990. This is autumn in the southern hemisphere, and consequently the pellet contents reveal non-breeding season diet of Gurney's Buzzard. To the best of our knowledge the


The growth and nodulation of Glycine wightii (formerly G. javanica L.) were studied in two experiments with several effective strains of Rhizobim under controlled environment, with the aim of producing lines with improved nodulation and nitrogenfixing ability. Significant differences were found between the accessions in their ability to nodulate and also between the stralns in their symbiotic effectiveness. Variation within lines for dry weight per nodule and time to nodule appearance was large. The results indicated that total nodule weight per plant is a suitable character for selection in a breeding programme to improve noddation in G. wightii. I. ~WTRODUCTION Many cultivars of G. wightii, formerly G. javanica (Verdcourt 1966), have been introduced into Australia. However, it has been found that although there is a wide range of adaptability most cultivars are difficult to establish (Tow 1960, 1967; Murtagh and Wilson 1962; Anon. 1967). It has been suggested that the establishment difficulties are due to poor nodulation. Nodulation and nitrogen fixation are influenced by differences between host lines, variation within them for characters associated with nodulation, and interrelations with Rhizobium strains in symbiosis. This paper reports work carried out to study the variation between lines representing a wide range of Glycine types, and their nodulation behaviour when they were associated with three Rhizobium strains.


Background: Indoor and outdoor gamma radiation exposure levels were measured in a total of 360 randomly selected dwellings categorized as local, semimodern and modern buildings across Ondo State, Nigeria to determine the annual effective doses. Materials and Methods: All radiation measurements were taken using a calibrated Kindenoo PG-15 Geiger Muller detector and a GPS for geographical coordinates of sample points. Equal number (360) sample point measurements were carried out for indoor and outdoor measurements. Measurements at each location point were performed holding the survey meter at 1 m above ground surface or floor to avoid unwanted effects of radiation from soil or building floor. The detector was also held at least six to seven meters away from buildings nearby in order to avoid unwanted effects of the building materials on outdoor measurements. Each measurement was repeated six times and the average was taken to represent the value for a sample point. Results: The average outdoor and indoor dose rates were determined as 263 ± 32 μSvh-1 and 213 ± 64 μSvh-1 respectively. The highest contribution to the total indoor dose was from the local buildings followed by semi modern buildings and the modern buildings contributed the least dose. The average annual effective dose was calculated as 1.56 ± 0.33 mSv, which is higher than the world average value (0.48 mSv). Conclusion: In view of the potential radiation resulting from building materials, comprehensive assessment of natural radiations in such materials is required.


Aortic stenosis is highly prevalent in the elderly, when symptomatic, is associated with high mortality. Although its treatment is mainly surgical, cumulative evidence has demonstrated that transcatheter aortic valve implantation is an effective and safe treatment option for selected patients, especially for inoperable and high-risk patients. The aim of this review is to discuss the advances in current and emergent devices, with special focus on clinical and safety outcomes in randomized clinical trials and registries.


Verification is an important step during the development process of safety-critical railway applications. Verifying the functionality already at early development stages can prevent integration issues in later steps. Hence, typically used technologies are co-simulation, Software-in-the-Loop testing and fault-injection. The latter is a good opportunity to inject faults deterministically into software or simulation models of a device. This way, the functionality of the network and end devices can be verified effectively in cases of errors. In this paper we extend an existing framework for distributed co-simulation by the means of fault-injection. Our mechanism is based on the CENELEC EN 50159 standard which defines seven message errors for communication. As the framework operates on a network-centric abstraction level, we inject the faults directly into the packets. The evaluation shows the applicability of our fault-injection mechanism based on an example application.

The article is devoted to new methodological techniques in the study of widely known sites of the early stage of Alanic culture of the Central Ciscaucasia — Zilgi hillfort and Beslan kurgan catacomb burial ground (RNO — Alania). The use of satellite images, low-altitude aerial photography, photogrammetry and magnetometric survey made it possible to obtain fundamentally new information about these well-studied sites and to specify their topographic and planigraphic features in the shortest time with minimal destructions. The excavations carried out in two areas of the Beslan necropolis helped to considerably refine its chronological framework, trace the development of the necropolis from the Zilgi hillfort to the southeastern periphery and identify the area of the most recent graves dating from the middle of the 7th century AD, which were made near the eastern border of unfortified settlement of Zilgi. The non-destructive survey methodology tested by the team has wide prospects for the study of Alanic culture sites of the Central Caucasus, especially at its early stage.

We review probabilistic principal components, principal fitted components, sufficient dimension reduction, and envelopes, arguing that at their core they are all based on variations of the conditional independence argument that Fisher used to develop his fundamental concept of sufficiency. We emphasize the foundations of the methods. Methodological details, derivations, and examples are included when they convey the flavor and implications of basic concepts. In addition to the main topics, this review covers extensions of probabilistic principal components, the central subspace and central mean subspace, sliced inverse regression, sliced average variance estimation, dimension reduction for covariance matrices, and response and predictor envelopes.


Experimental studies on major factors affecting thermal characteristics of the plate-type evaporative condenser,i.e.,air wet-bulb temperature,condensation temperature and relative moisture were conducted.The results showed that condensation temperature and condensation pressure increased with increasing inlet air wet-bulb temperature.Compressor power consumption was greatly affected by inlet air relative humidity and wet-bulb temperature.Comparisons based on the same vapor-compression refrigeration unit showed that the heat flux of the plate-type evaporative condenser was larger by 30.5% than the tube-type evaporative condenser when the condensation temperature was 38℃.The lower the inlet air wet-bulb temperature,the larger the difference between the heat stream density of the plate-type evaporative condenser and the tube-type evaporative condenser at the same condensation temperature.

4-Ethynyl- and 4-(prop-1-ynyl)phenylsilatranes (N(CH{sub 2}CH{sub 2}O){sub 3}SiR, R = C{sub 6}H{sub 4}-4-C{triple bond}CH or C{sub 6}H{sub 4}-4-C{triple bond}CCH{sub 3}) are highly toxic to houseflies (pretreated with piperonyl butoxide) and milkweed bugs (topical LD{sub 50}s 3-14 {mu}g/g) and to mice (intraperitoneal LD{sub 50}s 0.4-0.9 mg/kg), and they are moderately potent inhibitors of the ({sup 35}S)-tert-butylbicyclophosphorothionate or TBPS binding site (GABA-gated chloride channel) of mouse brain membranes. Scatchard analysis indicates noncompetitive interaction of 4-ethynylphenylsilatrane with the TBPS binding site. Phenylsilatrane analogues with 4-substituents of H, CH{sub 3}, Cl, Br, and C{triple bond}CSi(CH{sub 3}){sub 3} are highly toxic to mice but have little or no activity in the insect and receptor assays. Radioligand binding studies with (4-{sup 3}H)phenylsilatrane failed to reveal a specific binding site in mouse brain. Silatranes with R = H, CH{sub 3}, CH{sub 2}Cl, CH{double bond}CH{sub 2}, OCH{sub 2}CH{sub 3}, and C{sub 6}H{sub 4}-4-CH{sub 2}CH{sub 3} are of little or no activity in the insect and mouse toxicity and TBPS binding site assays as are the trithia and monocyclic analogues of phenylsilatrane. 4-Alkynylphenylsilatranes are new probes to examine the GABA receptor-ionophore complex of insects and mammals.

Employees, no doubt, are the main force in organizations, and their innovative behaviours are vital for outcome efficacy. Innovative organisations, therefore, need creative employees who generate new ideas for product or process of innovation. This study investigated the effect of six thinking hats creativity technique on innovative competence of social worker. A pretest-post-test quasi-experimental design was adopted for the study. Forty-eight (48) participants chosen among social workers in two randomly selected Non Governmental Organisations participated in the study. Data were collected using Innovative Competence Scale. Analysis of variance was employed for data analysis with significant level fixed at 0.05. Findings from the study revealed that the treatment significantly affect participants' innovative competence. Based on the results, the study recommended that creativity be integrated into the training programmes for personnel in the workplace.

Natural disasters are natural events that negatively affect human life and cause material and moral damages. As in the rest of the world, one of the biggest natural disasters after earthquakes in our country is floods. The flood event turns into a disaster in cases caused by human interventions such as the change of the river bed, the increase in the construction on the river sides, the blocking of the river perpendicular to the flow direction. In this study, risk maps for floods with different return intervals (25, 50, 100 years) were produced with GIS for Ayancık stream in Sinop province. As a result, when the flood risk maps were analyzed, the regions located in the floodplain were considered as very risky regions. In addition, it was concluded that the majority of the areas affected by the floods in all three turning ranges within the scope of the study area are located in the very risky region, while the extreme risk areas are less than the other risky groups.

The Republic of Macedonia is the smallest, poorest and most vulnerable country in the Balkans. It is a landlocked country, one of the successor states of the former Yugoslavia, from which it declared independence in 1991. It has borders with Kosovo to the northwest, Serbia to the north, Bulgaria to the east, Greece to the south, and Albania to the west – countries that have some kind of claim to its territory, culture and even its name. It isn't in the European Union. The Kingdom of Macedonia was established some time during the 7th Century BC. Macedonian dominance of Greece was secured by Philip II and subsequently by his son Alexander 'The Great'. Alexander was born in 356 BC in Pella, the ancient capital of Macedonia, situated now in the Greek part of Macedonia. From Macedonia he conquered territories all the way to India, including Persia, opening out a corridor for East-West discourse and trade [1]. After several wars against the Macedonians, the Romans defeated them in 146 BC and the country became part of the Roman Empire. Its vast arable land and rich pastures allowed huge fortunes to be amassed by the Roman rulersin a society based on slave labour. The centre of Roman power was transferred to Byzantium in the 4th Century AD and since then various armies have controlled the country, includingBulgarians, Serbs and the Ottoman empire (13th–19th centuries) [2]. The Republic of Macedonia is a pristine land with mountains, lakes and old cities. It has the economic, cultural and physical conditions to offer a good quality of life to its small population of about 2.1 million people. Well-being has decreased since the breakdown of the former Yugoslavia. This is due mostly to the de-industrialization process, and weak political institutions in the country. The climate and land are very favourable to agriculture. Most of the country enjoys a Mediterranean climate as, despite being a landlocked country, it is near to the Mediterranean Sea. This provides high quality land, varied food, excellent wine, good weather, and low pollution. However Skopje, where half of the population lives, has an unhealthy summer because it is situated in a valley that concentrates the pollution created by the vehicles. Despite this, it is worth a visit for the abundance of new gigantic bronze statues of ancient heroes, museums and excellent food and wines. Luckily, it still keeps a strong educational sector and the cultural scene is dynamic with several good museums in the capital. The population strongly and peacefully participates in the difficult political life of the country. The health sector needs improvements, as will be shown further in this article.


Previous studies of the anodic polarisation of titanium in chloride solutions have demonstrated that, when the potential across the oxide exceeds a critical value (12 to 14 volts), film growth ceases owing to breakdown of the oxide film and intense corrosion or pitting occurs at localised areas. Pitting of the titanium can, however, be prevented by having platinum in contact with the metal surface. In these circumstances the entire current will be conducted through the platinum and pitting of the titanium will occur only if the breakdown potential is exceeded. A continuous coating of platinum is not essential, and very high current densities can be applied to a titanium-platinum bielectrode in sea-water, or other highly conducting electrolytes containing chlorides, without exceeding the breakdown potential (I, 2). The use of platinised titanium as an anode for cathodic protection of structures in sea-water is now firmly established. The situation is, however, quite different if the electrolyte has a very high electrical resistance as, in these conditions, it is possible to exceed the critical potential with consequent film breakdown and pitting of the exposed titanium. A rod of titanium, coated with platinum over its lower half only, that has been anodically polarised in fresh water (specific conductivity 3 x I O ~ mhos 8 cm-'), using a cathode of equal length placed one inch from the anode, at 25 amp'ftz shows appreciable pitting. Owing to the geometry of the system and the very high IR drop through the electrolyte the potential of the titanium will increase with increasing distance from the platinum and, at a certain point, the breakdown potential will be exceeded. It has been observed, however, that the titanium adjacent to the platinum shows no evidence of pitting. If the experiment had been carried out in sea-water the titanium would have remained unattacked. Tantalum, unlike titanium, can be anodically polarised in sea-water without the occurrence of pitting, and film growth, as shown by the interference colours, proceeds until the potential is 160 volts, when the film breaks down. The thick oxide produced in these circumstances is not, however, firmly adherent to the metal and can be readily detached with Sellotape. The potential of tantalum during anodic polarisation can be demonstrated visually by the brilliant interference colows. If a tantalum-platinum bi-electrode (I >; I inch tantalum with platinum, 0. I x 0. I inch, welded to the centre) is anodically polarised in sea-water only a first-order blue film will be formed uniformly on the tantalum surface and current will then proceed through the platinum (Fig. 2u). In a low-conductivity water, however, the potential distribution is not uniform and the thickness of the oxide will increase with increasing distance from the platinum microelectrode. This results in a wedge-shaped oxide film (Fig. 2b) which gives rise to five orders of interference as a series of concentric rings around the platinum, as shown in Fig. I. Since the thickness of


Paul Lazarsfeld's social research organizations, as centres for cosmopolitan refugees who pioneered communications studies, were instrumental in producing some of the most prominent mass-culture critics in the post-war US—both native and e´migre´—including C. Wright Mills, Leo Lowenthal, Theodor Adorno, and David Riesman. But among Lazarsfeld's fellow Viennese colleagues, perhaps the most prominent in the contemporary popular mind was Ernest Dichter, a psychological consultant to marketers who probed the unconscious of consumer subjects in an effort to reveal their hidden motivations. Dichter was not a critic of mass culture but rather a celebrant who was embraced by the American business class. He entered into the public sphere, however, as the subject of criticism in journalist Vance Packard's exposé The Hidden Persuaders. Lazarsfeld saw no essential contradiction between the critics of mass culture and its industrial purveyors; instead, he saw these forces existing in a dialectical relationship with one another. In this sense, it was no accident that his research institutes nurtured both cultural critics and the agents of industrial mass society.


We propose a new modularity vision to integrate design modeling with programming. A system consists of not only program code but also design models. However, design models such as UML diagrams have been treated as not modules but complementary documents. This paper provides a novel idea that treats a design model as a first-class software module termed design module. A system cannot be complied without design modules. A developer has to create and modify not only program modules but also design modules. To realize design modules, we introduce Archface, an architectural interface mechanism. Archface exposes architectural points shared between design and code. Archface plays a role as a design interface for a design module and as a program interface for a program module. Arch-face type system automatically checks the consistency between design and code. Our approach can integrate research on design modeling with research on programming in terms of modularity. Additional costs are not needed to introduce design modules, because Archface descriptions can be generated from a model editor and Archface is just an extension of the notion of program interfaces. That is, we can substitute Archface for traditional program interfaces.


Objectives
To investigate the correlation between preoperative imaging features of central meningiomas and surgical cleavage and to comparatively analyze the clinical efficacy of the different surgical cleavages.

Methods
From February 2006 to February 2014, the correlation between imaging features and surgical cleavage in 97 patients with center meningioma admitted to the Department of Neurosurgery, People's Hospital of Zhengzhou University were analyzed retrospectively. The relationship between imaging features and surgical cleavage of the tumors were tested by the univariate analysis. Kaplan-Meier survival analysis and multivariate logistic regression analysis were used to assess whether the imaging parameters predicted the surgical cleavage. Cox regression model was used to analyze the relationship between surgical cleavage or overall survival (OS) and progression free survival (PFS).

Results
The result of single factor analysis showed that the relationships between the peritumoral edema and the position of venous sinus, the cortical infiltration and diffusion weighted imaging (DWI) signal intensity and surgical cleavage had obvious relevance (all P 0.05). Multivariate logistic regression analysis showed that cortical infiltration was the most important independent predictor of surgical cleavage on central meningioma (P<0.01), others followed by DWI hyperintensity, parasagittal sinus, and peritumoral edema (P<0.01). The results of Kaplan-Meier analysis show that the median OS and median PFS in patients with the central grade Ⅱ meningioma. Cox regression model analysis showed that the age, WHO pathological grade, and surgical cleavage could be used as the independent predictive factors of influencing prognosis (P<0.05).

Conclusions
The peritumoral edema provided by preoperative imaging, the relationship with the position of venous sinus, cortical infiltration and DWI signal intensity may predict the surgical cleavage of meningioma, and the surgical cleavage is directly associated with the prognosis of patients.

Key words:
Meningioma; Magnetic resonance imaging; Surgical cleavage; Clinical effect


Background: Genome alterations need to be investigated before clinical application of iPS cells. Results: Reprogramming and gene targeting can generate substantial but different genomic variations. Conclusion: Stringent genomic monitoring and selection are needed both at the time of iPSC derivation and after gene targeting. Significance: This study examined the genome instability during iPSC generation and subsequent gene correction and revealed different genome alterations at each step. The generation of personalized induced pluripotent stem cells (iPSCs) followed by targeted genome editing provides an opportunity for developing customized effective cellular therapies for genetic disorders. However, it is critical to ascertain whether edited iPSCs harbor unfavorable genomic variations before their clinical application. To examine the mutation status of the edited iPSC genome and trace the origin of possible mutations at different steps, we have generated virus-free iPSCs from amniotic cells carrying homozygous point mutations in β-hemoglobin gene (HBB) that cause severe β-thalassemia (β-Thal), corrected the mutations in both HBB alleles by zinc finger nuclease-aided gene targeting, and obtained the final HBB gene-corrected iPSCs by excising the exogenous drug resistance gene with Cre recombinase. Through comparative genomic hybridization and whole-exome sequencing, we uncovered seven copy number variations, five small insertions/deletions, and 64 single nucleotide variations (SNVs) in β-Thal iPSCs before the gene targeting step and found a single small copy number variation, 19 insertions/deletions, and 340 single nucleotide variations in the final gene-corrected β-Thal iPSCs. Our data revealed that substantial but different genomic variations occurred at factor-induced somatic cell reprogramming and zinc finger nuclease-aided gene targeting steps, suggesting that stringent genomic monitoring and selection are needed both at the time of iPSC derivation and after gene targeting.

Study of the Fatigue Life of Steel Catenary Risers in Interaction with the Seabed. (December 2010) Ali Nakhaee, B.S., University of Tehran, M.S., University of Tehran Chair of Advisory Committee: Dr. Jun Zhang The fatigue life of a Steel Catenary Riser (SCR) near its touch-down zone is substantially affected by its interaction with the seabed. Hence, accurate estimate of its fatigue life requires the understanding and realistic modeling of the interaction between them. The interaction between SCR and the seabed depends on many factors, such as soil properties, riser characteristics, and the development of trenching at the seafloor. Existing approaches for modeling the seabed in interaction with a SCR approximate the seabed soil by a linear or nonlinear spring and a dashpot which respectively represent the stiffness and damping of the soil. However, they do not take into account certain phenomena resulting from plastic deformation or degradation of the seabed soil, such as trenching. In this study, a more realistic approach is developed for simulating the interaction between a SCR and the seabed soil. In addition to the use of a realistic P-y curve (where P stands for the supporting or resistance force of the seafloor and y for the vertical penetration of the riser into the soil) to simulate the soil deformation during its


From the fundamental laws of elasticity, we write a model for the contact between two membranes and we perform the analysis of the corresponding system of variational inequalities. We propose a finite element discretization of this problem and prove its well-posedness. We also establish ap rioriand a posteriori error estimates.


In this Keynote address, I will explore the idea of Selfscapes to a more-than human-world.

I will look at a few examples of my earlier work and then trace the subsequent (and I argue logical) development of a link between linguistic, visual and musical notation/expression in the work.

I will then discuss how collaborative, practice-based research has led the development of the project.

Finally, and in the main part of this talk/discussion, I will focus in on one project – Singing the World – a collaborative project between myself, composer and musician Bennett Hogg, printmaker Alex Charrington of Charrington Editions, Glass-maker Ayako Tani, Multi-media artist Andrew Richardson and poet Jake Campbell.

Ever since 1716, when the first concept of building a vehicle to operate with an air cushion was presented, the world remained fascinated by this concept. This article presents a study on important parameters of the flow into the inner cavity of a simple plenum hull, the first configuration of the air cushion vehicle. In order to achieve this, six constructive models were chosen, the only major difference being the angle of inclination at the bottom of the hull. The paper presents the specific mathematical model adapted for this type of configuration, the imposed constructive dimensions, the steps of numerical analysis and results. An important step of this analysis is the estimation of the total weight of each prototype according to the lower hull angle. The estimate was performed using Catia software and the actual analysis was completed using Matlab.

In recent years, there has been a great effort to prove the security of quantum key distribution (QKD) with a minimum number of assumptions. Besides its intrinsic theoretical interest, this would allow for larger tolerance against device imperfections in the actual implementations. However, even in this device-independent scenario, one assumption seems unavoidable, that is, the presence of a protected space devoid of any unwanted information leakage in which the legitimate parties can privately generate, process and store their classical data. In this paper we relax this unrealistic and hardly feasible assumption and introduce a general formalism to tackle the information leakage problem in most of existing QKD systems. More specifically, we prove the security of optical QKD systems using phase and intensity modulators in their transmitters, which leak the setting information in an arbitrary manner. We apply our security proof to cases of practical interest and show key rates similar to those obtained in a perfectly shielded environment. Our work constitutes a fundamental step forward in guaranteeing implementation security of quantum communication systems.


Many studies of the relationship between the state and interest organizations conclude that the state is captured by sectoral interests. The state is not autonomous in a capitalist society. However, does the neo-corporatist practice necessarily imply a captured state? The author examines the dependencies of the state on functional groups and proposes that corporatism in fact makes it a stronger and more autonomous state. Further, different criteria of autonomy are discussed. The public interest is explored through the concept of communicative action. Finally, the author tries to delimit the concept of autonomy in analysing some recent trends of development in Norwegian public policy.


Berlin is like Gulliver: a colossal urban center that is economically depressed and entangled in a stifling web of special interest politics. With an economy not nearly competitive enough to support jobs for its population of 4 to 5 million people, the city region of Berlin is faced with challenges on an almost epic scale. These include the reestablishment of a market economy, the creation of conditions for the successful fusion of two populations from vastly different socio-economic systems into a single productive society, and the removal of a deeply engrained mentality of dependence. Reunification represented a complete structural schism that attracted tremendous attention to Berlin. Yet the city can only succeed in the long term by mobilizing its potential. Berlin must make use of its position as a gateway to Eastern Europe, develop a dynamic tertiary sector (strong universities, content industries, etc.), take advantage of its social and cultural distinctiveness, and drop its status as a separate Bun...

Humankind exists in constant relations of economic, political, scientific and cultural nature. The flow of borrowed words and terms from the English language into Ukrainian has been growing rapidly recently. It is a source that enriches the lexicon of our native language. As of today, there exists the necessity for a comprehensive research of Ukrainian youth slang as a separate layer of the national language, which would take into the account English borrowings. This is especially true of the computer technology field. The other important task would be to clarify the expediency of using English originated words in the modern Ukrainian youth lexicon.


Under the background of the working face influenced on the water fluctuation area(WFA) in Northern Shaanxi Province,the dynamic fluid-solid coupling physical model was designed.Based on observation of separation layer development,the water flowing fractured zone heights,subsidence of the water-resisting key clay layer and dynamic dive table while mining,as well as water recovery while mining-stop,the mechanism of dynamic dive table variation in WFA was studied.The results show that elastic deformation to the bedrock and plastic deformation to the aquifuge clay are the key to simulation of additional stress-strain flied,and hydrophysical character of sandy layer is the key to simulation of mining seepage field in WFA.While mining,with successive curve,bed separation appearance as well as fracture of inferior key strata,the aquifuge clay keeps the stabilization and gradually forms the subsidence basin,the dive table rapid drawdown occurs cyclically during the formation of subsidence basin.Meanwhile,owing to sandy aquifer is flowing and supplied,the closure of the bed separation results in drawdown of dive table.After mining,the lateral recharge of dive results in water recovering quickly in early stage but slowly in later stage.


Mutual health organizations (MHOs) are community and employment-based groupings that have grown progressively in West and Central Africa (WCA) in recent years. With this growth has come interest from governments, nongovernmental organizations, and international organizations, particularly those interested in new and innovative approaches to the difficult issues of health care financing and access in the subregion. From mid-1997 to mid-1998 a consultative group led by the United States Agency for International Development-funded Partnerships for Health Reform, the International Labor Office-Appui associatif et coopJratif aux initiatives de dJveloppement B la base/Strategies and Tools against Social Exclusion and Poverty, SolidaritJ Mondiale, and Alliance Nationale des MutualitJs de Belgique, with participation from the Fonds d'aide à la coopJration, the United Nations Children's Fund, the Institut français de recherche scientifique pour le développment en coopération, and the Deutsche Gesellschaft fur Technische Zusammenarbeit undertook a one-year program of research into the actual and potential contributions of MHOs to the financing of, delivery of, and access to health care in WCA. The study represents an important step forward in documenting and understanding the MHO experience in the WCA subregion. The main purpose is to present information that could be of use to key actors in the development of the MHOs: the members and leaders of those organizations; health care providers; policymakers, especially WCA ministries of health and labor; development partners (external cooperation agencies and technical support institutions); other MHO promoters such as trade unions; and mutualist organizations and associations outside the health sector. This study has confirmed the emergence of a mutual health scheme movement in WCA. These schemes are generally on a small to medium scale in terms of membership. Most are also young: about twothirds of the 50 MHOs (from six countries) in the inventory survey were less than three years old. At present, MHO activities affect only a small fraction of the populations of the countries involved. However, this study shows that they have great potential to embrace more people, as well as to contribute more to the health care sectors of their countries. The study analyzes MHOs' actual and potential contributions in the areas of (a) access to health care and extending social protection to disadvantaged sections of the population, (b) resource mobilization, (c) efficiency in the health sector, (d) quality improvement, and (e) democratic governance. Given the youth of most of the schemes, assessing their long-term sustainability on the basis of experience to date is not possible. However, the examination of some of their design and institutional features; their administrative and managerial capacities; and their financial performance, including dues collection rates, reveals room for improvement. This study makes a number of recommendations for MHOs that principally concern design features to enhance scheme success. Recommendations for promoters and development partners deal with reinforcing the MHOs' institutional, managerial, and administrative capacities. Health care service providers with experience in contracting are advised to assist MHOs with pricing and establishing relationships with providers. Finally, recommendations are made on the role of governments in establishing a favorable legal, fiscal, and institutional context. No study can deal exhaustively with all the aspects of a phenomenon as complex and diverse as MHOs, and this study does not claim to have done so. In particular, the study did not investigate the social movement dimension or aspiration of the MHOs, which is potentially one of their major and vital contributions to social and civic life. This paper concludes with an outline of a number of areas that would benefit from further examination.


The goal of this turorial is to provide a thorough theoretical overview of the state-of-the-art in Music Information Retrieval followed by a practical hands-on demonstration of several existing tools and resources that can be used for research in this area. Specific emphasis will be given on how MIR techniques relate to other fields of current multimedia research. MIR is an inherently interdisciplinary area touching on several research areas such as digital signal processing, machine learning, perception, visualization, human-computer interaction, content-based retrieval and digital libraries. Music has several unique characteristics that differentiate it from other areas of multimedia research. The different problems and techniques proposed to solve them that will described in the first part of the tutorial will be followed with concrete practical examples of applying these techniques using existing software tools and datasets.


The extraction-turbidimetry was used to determine hydrophobic percentage of microorganisms,the hydrophobic property of nitrifying bacteria and denitrifying bacteria with different pH value,temperature and growth cycle were studied,meanwhile,the variation of coal suspension Zeta potential and sedimentation features after coal powder absorbed different hydrophobic percentage of microorganisms were researched.It is shown that hydrophobic percentage of various strains are different.The hydrophobic percentage of active nitrifying bacteria is more than 90%,but it significantly decreases in the decline phase of cells.While,the hydrophobic percentage of denitrifying bacteria is less than 20%.Growth conditions on the influence of the bacteria hydrophobic in turn are pH value,temperature,and inactivated,its change rules are different to various strains.The study on coal suspension ξ potential proves that the absorption of nitrifying bacteria on coal surface is prior to minerals.Nitrifying bacteria and denitrifying bacteria both have biological flocculation effect on coal suspension.


In a mixed suspension of rods and small polymer coils, the rods adsorb onto a hard wall in contact with the suspension. This adsorption is studied in the low density of rods limit. It is driven by depletion forces and is much stronger for long rods than for spheres. This is shown by means of exact, numerical, calculations and an approximate theory.


Abstract A reinvestigation of the microwave spectrum of tricarbonyl(cyclobutadiene) iron has revealed a new fine structure. This is not in agreement with previously published results. In this paper a first attempt of the appropriate description of the molecules internal dynamics is made.


We study the statistical properties of the combined emission of a population of discrete sources. In particular, we consider the dependence of their total luminosity ( L tot = ∑ k L k ) and fractional rms tot variability on the number of sources n or on the normalization of the luminosity function. We show that due to small number statistics a regime exists, in which L tot grows non-linearly with n . This is in apparent contradiction with the seemingly obvious prediction L tot = ∫ LdN / dLdL ~ n . In this non-linear regime, the rms tot decreases with n significantly more slowly than expected from the rms ~ 1/ n 1/2 averaging law. Only in the limit of n >> 1 do these quantities behave as intuitively expected, L tot ~ n and rms tot ~ 1/ n 1/2 . Using the total X-ray luminosity of a galaxy due to its X-ray binary population as an example, we show that the L X –SFR and L X –M * relations predicted from the respective ``universal'' luminosity functions of high and low mass X-ray binaries are in a good agreement with observations.


In the paper,deficiency of water reducer used at home nowadays has been depicted,and the polycarboxylate high performance water-reducer,copolymer of maleic anhydride,macro-molecular monomer etc,has been synthesized in the aqueous system by the initiation of per-sulfate.The result shows that the water-reducer has some high dispersing ability,enhancing intensity ability,and long keeping time of fluidity,which has better dispersion and enhancement effect,compared with the naphthalene series high performance water reducers.


A new phase of globalization has made the world cognizant of the job losses, inequality of gains across countries and socio-economic sectors, and climate degradation that has resulted from prior global business practices. We examine what changes international business (IB) education should consider as these patterns evolve. Non-routine analytical skills and global interpersonal skills will still be important in the changing economy. However, evidence suggests that IB education should also emphasize broader knowledge of politics, institutions, sociology, and anthropology in order to help future business leaders navigate and balance the increasingly complex requirements of both local and global stakeholder interests.


Depression is common in dementia, with important clinical implications. Few studies of depression in dementia with Lewy bodies are available, and the results are inconsistent.


The mechanical splice characteristics of a single-mode hole-assisted fiber (SM-HAF) are investigated both numerically and experimentally. Mode-coupling theory is used to investigate the mechanical splice loss characteristic of the HAF. We introduced an air filling fraction and a \bm V-parameter to allow us to consider an HAF with arbitrary structural parameters. We derive the optimum conditions (e.g., refractive index and temperature coefficient) of a solid-type refractive index matching material to realize good splice and return loss characteristics simultaneously. The validity of the derived conditions is investigated experimentally. Finally, we confirm that we can achieve comparable splice characteristics to those of conventional single-mode fiber splices by using the optimized refractive index matching material independent of the structural parameters of the SM-HAF.


Service life testing of asphalt specimen in laboratory frequently uses a highly specified and constant load. Real roads experience a considerable distribution of both placement and size of load which leads to a variety of material responses. Fatigue criteria derived from lab tests often need a large shift factor in order to match the experience on real roads. Data from an instrumented test site in southern Sweden (E4, Eket) has been used for analysis of how the variation in load placement, load size and response direction may contribute to the shift factor. The variation in measured strains at the bottom of the AC-layer has been compared with the Swedish design code ATB Road and has been used as input to the asphalt strain criterion in this code. The results are discussed with use of other contributions to the shift factor such as healing.


An efficient protocol was developed to achieve the aryltrifluoroalkylation of hydroxy alkenes via radical trifluoromethylation-triggered aryl migration. This method possesses several interesting features: (I) visible light is used as the sole promoter; (II) a new version of Umemoto's reagent [2,8-difluoro-S-(trifluoromethyl)dibenzothiophenium triflate], which is stable, cheap and recyclable, serves as the CF3 source; (III) the aryl migration is chemoselective; (IV) structurally diverse trifluoromethyl ketones can be produced.


The author examines some Balkan Sprachbund features that appear in neighbouring dialects of individual languages, but are absent from the other dialects of the languages to which these dialects belong; as well as some features that function in neighbouring Balkan languages of different families, but are absent from the other Balkan languages of the same family. Displaying individual typological features of the Balkan languages in interaction with other features in the structure of the DP or the clause and taking into consideration sociolinguistic factors and dialectal variation, she tries to identify structural similarities, establish links between structural differences, and shed light upon a number of pertinent Balkan Sprachbund questions.


It is important to grasp biometric data in real time for prompt action in the event of a safety accident at a work site where the risk of safety accidents exists. Among them, blood oxygen saturation is the most important factor in maintaining human life, so real-time oxygen saturation measurement and monitoring is necessary according to the situation as a preemptive response for worker safety management. By receiving real-time bio-signals from workers wearing health and life-risk protective clothing, and sharing and analyzing the worker's risk status in an external system, it is possible to diagnose the worker's current condition and efficiently respond to emergencies that may occur to the worker. In this paper, we propose a wearable oxygen saturation measurement platform technology that can monitor the risk of harmful gases and oxygen saturation of the wearer in real time and ensure the wearer's activity and safety in order to cope with emergency situations at the scene of an accident. If we overcome the limitations identified through the results of the proposed system later and apply improved biodata such as motion correction to the platform, we expect that it will be usable not only in hazardous gas environments, but also in hospitals and homes for emergency patients.


Abstract Numerical and asymptotic stochastic partitioning of goodness-of-fit statistics are considered for a broad class of simultaneous multivariate categorical response models. These simultaneous models impose constraints on the joint and marginal distributions of categorical response variables. Under certain conditions, the tenability of the corresponding simultaneous hypothesis can be assessed by separately testing the two subhypotheses: one regarding the joint distributions and the other regarding the marginal distributions. Specifically, easily verifiable sufficient conditions are introduced that allow us to partition the overall goodness-of-fit statistic into two interesting goodness-of-fit statistics: one for testing whether the joint distribution model holds and the other for testing whether the marginal distribution model holds. Moreover, it is proven that when the sufficient conditions hold and the simultaneous hypothesis is true, the two component goodness-of-fit statistics are asymptotically ...


Purpose:This paper reviews the literature on state-of-the-art 3D and 4D printing technology in the fashion mass customization context and proposes an innovative design concept for improving independent designers' and small and medium enterprises' (SMEs) practice, premised on commercialized technology and accessible materials in the fashion mass customization business.
Design/methodology/approach:The literature review of 3D and 4D printing technologies enabled discussion of the possibilities of using them for mass customization, especially in the fashion industry. Then the study presented a prototype suggesting an approach to improve mass customization by combining two technologies.
Findings:The intrinsic worth of 3D and 4D printing technology has inspired researchers to strike an innovative path towards exploiting the potential for mass customization in the fashion industry, through embedding shape memory materials into 3D-printed objects. 4D printing was confirmed as offering potential for application in the fashion industry.
Research limitations:A fashion accessory case was presented, exemplifying such 3D/4D printed fashion items, but more studies experimenting with other types of fashion products are warranted.
Originality/value:This paper establishes appropriate knowledge flows between 4D printing technology and its commercial possibilities, by identifying the strengths of 4D printing technology, particularly in the fashion industry. In addition, integration of 3D and 4D printing components is proposed, to reduce consumer return rate and increase products' hedonic value by facilitating change of shape of the 3D-printed object post printing.


The placental syncytiotrophoblast is a giant multinucleated cell that forms a tree-like structure and regulates transport between mother and baby during development. It is maintained throughout pregnancy by continuous fusion of trophoblast cells, and disruptions in fusion are associated with considerable adverse health effects including diseases such as preeclampsia. Developing predictive control over cell fusion in culture models is hence of critical importance in placental drug discovery and transport studies; but this can currently be only partially achieved with biochemical factors. Here, we investigate whether biophysical signals associated with budding morphogenesis during development of the placental villous tree can synergistically direct and enhance cultured trophoblast fusion. We use micropatterning techniques to manipulate physical stresses in engineered microtissues, and demonstrate that biomimetic geometries simulating budding robustly enhances fusion and alter spatial patterns of synthesis of pregnancy-related hormones. These findings indicate that biophysical signals play a previously unrecognized and significant role in regulating placental fusion and function, in synergy with established soluble signals. More broadly, our studies demonstrate that biomimetic strategies focusing on tissue mechanics can be important approaches to design, build, and test placental tissue cultures for future studies of pregnancy-related drug safety, efficacy and discovery.


Radio frequency identification (RFID) technology has been widely applied in many fields such as anti-counterfeiting, access control system and security management system. The main modules of the receiver are designed and simulationed basised on SMIC 0.18-μm CMOS technology. The low noise amplifier (LNA) consists of two stages of circuits. The first stage is a source inductance feedback amplifier and the second stage is a cascode structure amplifier, which makes the gain and noise figure improved effectively. An improved Gilibert active dual balanced mixer is used to improve the noise and conversion gain by using the static current injection and the local oscillator buffer technique, and the output buffer is added to enhance the mixer conversion gain and linearity. Finally, a zero IF receiver is implemented by the designed LNA and two I/Q branches of mixers. The simulation results show that the receiver gives 19.14 dB gain with 8.31dB noise figure, and the input 1dB compression point of 2.37dBm. It meets the requirement of RF front-end in 900MHz-RFID receiver.


While developing and debugging circuits or digital systems it is useful to visualize, capture and generate electric signals. This is needed in some courses in the area of Embedded Systems or Cyber-Physical Systems at IST, where students may work with sensors and digital communication during laboratory classes and in their projects for these courses. These tasks require specialized and expensive equipment that is not usually available in Computer Science laboratories nor at students' homes. Arduino Starter Kits are already available in some laboratory rooms at IST. This document describes the system that was developed to allow an Arduino Uno and a computer application to be used as an oscilloscope, logic analyzer and signal generator. It is able to sample up to 6 analog channels and up to 8 digital channels simultaneously. Captured signals can be stored for later analysis. Using an external DAC, the system is able to generate analog signals with various shapes. The logic analyzer functionality allows samples on multiple digital channels to be interpreted in order to decode and display I2C communication. The system evaluation shows that it is able to continuously sample a single analog channel at 76.9 kSps or 6 digital channels at 50 kHz, although with some constraints. Sample rates can be higher if not continuous, reaching 5.33 MHz for 6 digital channels. A few laboratory exercises are described to demonstrate some of the functionality. The system and these exercises were improved based on user feedback.

Corporate image can be defined as the picture that the organization visualizes in the minds of various audiences. The corporate image must be realistic and convincing since it is the duty of the organization to create and maintain trust of the internal and external target audience. Organizational commitment means that employees feel the sense of belonging to the organization and provide an advantage for the organization to benefit from the human resources needed for the continuity of the organization. Researches conducted have showed that employees with high organizational commitment had higher motivation and productivity; however, negative behaviors such as absenteeism, being late to work, and quitting the job were less common. Positive corporate image contributes to provision of high quality service to the organization by ensuring an attractive alternative for qualified personnel, while qualified personnel working with high commitment and motivation to contribute to the development of positive corporate image. This process of interaction increases the rates of preference for the organization by both internal and external stakeholders. Since the scope of services is human health, image management in health institutions is much more difficult and important than other institutions. In order to increase the competitiveness in today's conditions; it is very important that health institution managers work to create a positive corporate image and to increase employees' commitment. In this study, studies examining the relationship between perception of corporate image and organizational commitment in the health sector are evaluated.


High penetration of variable and non-programmable distributed generation has brought new challenges to the power system operation and is highlighting the need of a smarter grid. One of the key requirements in this regard is developing and deploying smart metering systems in distribution networks. In this paper we present the actual situation in the Italian distribution networks and we discuss the opportunities and challenges of applying new metering systems and introducing a flexible, multi-utility, multi-service metering architecture. Some off-the-shelf or prototype smart meters, selected to be tested in an ongoing European project, named FLEXMETER, are presented.

Further, through an experiment, the study empirically verifies the kind of recalled information depending on the flow which forms users' attitudes towards the content. The experiment was conducted with a factor design between 3X2 subjects. Hyundai Motor's Ioniq VR video was conducted, and a questionnaire of 143 subjects was used for the study. The results revealed that positive attitudes were formed towards the advertisement used in the experiment when the level of emotional presence was the highest. In addition, higher flow levels established positive attitudes towards the advertisement. and Cognitive presence's effects on memory, ARM such as product-attribute information was found to increase when the flow level is high; however, GRM such as overall product evaluation was found to increase when the flow level is low.


Expected holding period for individual investors is a central concept in market microstructure. It has been used to justify that liquidity affects stock returns (Amihud and Mendelson, 1986). Existing empirical research however only considers indirect proxies of holding periods, estimated from for example turnover. In this paper we use data on holding periods for all investors in a stock market over a 14 year period to investigate links between holding periods, liquidity, and asset returns. We show that existing empirical proxies for holding periods are only imperfectly related to actual holding periods. We also show that microstructure measures of liquidity are important determinants of the holding period decision for individual investors. However, we find only weak evidence of a link between holding periods and returns. Traditional measures of liquidity, such as turnover and bid/ask spreads, are more closely related to stock returns.


Consider the semiparameter regression modely_i=x_iβ+g(t_i)+e_i,1≤i≤n where β is a unknown parameter, g(t) is an unknown Borel function on \, x_i is a random design, random error sequences {e_i,1≤i≤n} is martingale difference sequences, {t_i} is constant sequence on\. In the paper, the estimators of β g(t) are established by wavelet method, and stably convergence to quasi-distribution function G in distribution about n(β∧-β) is studied.

Over the last few decades, public programs have driven the gradual adoption of information and communication technologies (ICTs) in education. The most ambitious project in Spain so far was Escuela 2.0, which provided students from the regions that opted into the program with laptops. The objective of this paper is to evaluate the impact of this program on school performance and productivity. To do this, we developed a new methodological approach based on combining causal inference techniques and the analysis of production frontiers. We calculated the differences in productivity and performance between treated and control schools using the base-group Camanho–Dyson Malmquist index and the base-group performance gap index. We estimate the impact of the program as the variation of these differences, following the essence of the difference-in-differences analysis. The main results are that Escuela 2.0 had a negative impact on performance and productivity.


At the peak of the Cultural Revolution, the barefoot doctor initiative and the production brigade medical stations where these practitioners worked were established to improve health-care service across rural China. The story of barefoot doctors formally began in 1968, when the People's Daily published a report in September announcing "a revolution in medical education through the growth of the barefoot doctors" in a Shanghai commune; another article that December introduced the "cooperative medical service" in the Leyuan commune of Hubei (31–32). Technically speaking, "barefoot doctors" ceased to exist in 1985, when the health minister Chen Minzhang announced the end of the term's usage in official Chinese discourse (175). Few aspects of Maoist China have acquired global repute as positive as the barefoot doctor program. In the late 1970s, the program even appealed to the World Health Organization (WHO), which promoted it as a model of primary health care and preventive medicine for developing countries (2). Drawing on local archives, published sources, and interviews with former barefoot doctors and, to a lesser extent, their patients, this book significantly deepens our understanding of the role that barefoot doctors had played in transforming medical practice, ideas, education, market, institutions, and professionalization in the socialist period. Although the book is centered on Jiang Village, Yuhang County, in Zhejiang, this microhistorical focus enables the author to deduce broader compelling insights concerning the significance of the barefoot doctor program for rural health-care reform since the early 1950s. The context for this narrative took concrete shapewith the advent of the Communist regime in 1949, when county hospitals gradually replaced existing county clinics (which had been primarily administered by the Nationalist government) and, more importantly, when township-level union clinics were developed to form a two-tier state medical system. The introduction of barefoot doctors in the late 1960s generated a further downward extension of this system. The rise of cooperative medi-


The extent of fueltheft from pipelines in Mexico is now so great that it is becoming a serious financial burden for state-owned petroleum company Pemex and, more broadly, may pose a challenge to the implementation of policies designed to liberalize Mexico's gasoline market, writes postdoctoral fellow Adrian Duhalt.


Development actors increasingly claim that their interventions are contributing to women's economic empowerment, and donors require that monitoring and evaluation systems capture these empowerment outcomes. However, there are divergent views and perspectives among both development policy makers and among grassroots women themselves on what constitutes 'women's economic empowerment' (Kabeer 2012: 7-10; Eyben 2011: 1). Differences relate to whether empowerment is seen as an end in itself, or a means to broader developmental goals; how broadly or narrowly economic the definition is; and whether empowerment is primarily seen as having the ability to 'compete' in the market, or encompasses the capacity to challenge structural inequalities in the market and beyond (Kabeer ibid). Related to this, there is also considerable debate on what measures constitute rigorous or comparable evidence of economic empowerment, and whether it is even possible to 'measure' empowerment across different contexts (Alkire et al. 2012; Okali 2012; Golla et al. 2011; Eyben et al. 2008; Kabeer 1999).


Introduction:  We investigated the second‐generation tyrosine kinase inhibitors, dasatinib and nilotinib, for their potential to overcome resistance in the imatinib‐resistant K562 cell line, and evaluated whether rapamycin, an mammalian target of rapamycin (mTOR) inhibitor, and bortezomib, a proteasome inhibitor, could increase imatinib sensitivity in resistant cell lines.


The banking sector has undergone a major revolution with the advent of digital transformation. The entry of Fintech and tech giants such as Google, Amazon, and Facebook have introduced convenient banking that is easy to understand and use. In this competitive environment, banks are realizing the importance of customer service and satisfaction and want to pay close attention to the Voice of Customer to improve the customer experience. By analyzing and getting insights from customer feedback, banks will have better information to make strategic decisions. In their quest to better understand their customers, banks are seeking artificial intelligence (AI) solutions in the form the of sentiment analysis. What is sentiment analysis? In simple words, sentiment analysis is the process of detecting a customer's reaction to a product, brand, situation or event through texts, posts, reviews, and other digital content. Using sentiment analysis, business leaders can gain deep insight into how their customers think and feel. The analysis can help in tracking customer opinions over a period of time, determine customer segmentation, plan product improvements, prioritize customer service issues, and many more business use cases.

The effect of Piracetam on the MST has been evaluated in 3 children with homozygous sickle cell disease, and in 1 child and 2 adults with sickle cell β thalassaemia. The MST was measured using 99 Tern labelled autologous red cells before and during treatment with Piracetam (160 mg/kg/d). Tests for in vitro fi1terabi1ity of red cells were performed and an improvement of the in vitro deformabi1ity was observed in all the patients. A shortening of the MST was also observed :


Some occupations and organizations rely heavily on trust, as their members' roles involve risk and are interdependent. Trust can emerge from two sources: knowledge or evidence that is meaningful in that context, which has been studied extensively in the literature on trust, and faith, which has not. Through a multi-phase, largely inductive study of firefighters in the United States, we explore processes that facilitate and maintain leaps of faith. These processes are critical to trust under high uncertainty, when direct experience in a task domain is chronically limited, as is the case in our context because very few calls coming into a fire station are fire related. We suggest that leaps of faith are initiated and perpetuated through two sets of dynamics: supporting and sustaining. Supporting dynamics, such as telling stories about fighting fires, evoke domain-relevant standards that are applied to weak, non-domain-specific evidence, such as how routine tasks are performed at the fire station, to help members feel a sense of certainty about whom to trust. Sustaining dynamics both limit the impact of new evidence about trustworthiness and bolster one's sense of certainty surrounding existing evidence. These two sets of dynamics, embedded in broader task and occupational conditions, act together as a largely closed system that allows trustors to be at peace with the uncertainty surrounding trust assessments—they make leaps of faith possible by increasing certainty and inhibiting doubt. Our study helps address key questions in both psychological and sociological treatments of trust, exploring an enigmatic phenomenon core to the concept of trust but rarely examined.


The paper presents the results of analyses concerning a new approach to approximating trajectory of mining-induced horizontal displacements. Analyses aimed at finding the most effective method of fitting data to the trajectory of mining-induced horizontal displacements. Two variants were made. In the first, the direct least square fitting (DLSF) method was applied based on the minimization of the objective function defined in the form of an algebraic distance. In the second, the effectiveness of differential-free optimization methods (DFO) was verified. As part of this study, the following methods were tested: genetic algorithms (GA), differential evolution (DE) and particle swarm optimization (PSO). The data for the analysis were measurements of on the ground surface caused by the mining progressive work at face no. 698 of the German Prospel-Haniel mine. The results obtained were compared in terms of the fitting quality, the stability of the results and the time needed to carry out the calculations. Finally, it was found that the direct least square fitting (DLSF) approach is the most effective for the analyzed registration data base. In the authors' opinion, this is dictated by the angular range in which the measurements within a given measuring point oscillated.


In this study, a survey was conducted on college students who had received education on food service entrepreneurship at the culinary and catering college and wished to start a business. As a result of the analysis, it was found that the motivation to start a restaurant business had a significant effect on the satisfaction of entrepreneurship education, but it did not appear to have a significant effect on the sense of self-efficacy. . In addition, self-efficacy was found to have a significant effect on entrepreneurial intention, and it was confirmed that both men and women played a moderating role in the relationship between entrepreneurship education satisfaction and self-efficacy and entrepreneurial intention.


In the past few decades, opinions about informal or peer-topeer human milk sharing have fallen firmly in either the pro or con camp. Those who believe in prohibition of the practice include the American Academy of Pediatrics (AAP; Meek et al., 2022), the Canadian Paediatric Society (Pound et al., 2020), and both the Human Milk Banking Association of North America and the European Milk Bank Association (EMBA & HMBANA, 2015). Most statements written against the practice rely on a single study by Geraghty et al. (2011) that found various unwelcome additions to the human milk they anonymously bought through various sources on the internet. Those in support of milk sharing include a growing cadre of researchers, many of whom have conducted indepth analyses of the practices, networks, and communities that exist as a result of this age-old practice (Falls, 2017; Gribble, 2013; Palmquist, 2015; Peregoy et al., 2021; Shaw & Morgan, 2017; Wilson, 2018). Another contribution to this expanding field is Sharing Milk: Intimacy, Materiality and Bio-Communities of Practice: sociologist Shannon Carter and medical anthropologist Beatriz Reyes-Foster's study of a Central Florida milk sharing community based on in-depth interviews with 33 research participants, an online survey of 392 respondents, and actor-network techniques "following the milk" from donor to recipient. Similar to Fall's (2017) White Gold: Stories of Breast Milk Sharing and Wilson's (2018) Others' Milk: The Potential of Exceptional Breastfeeding, Carter and ReyesFoster's Sharing Milk provides intimate insight into nonnormative human milk feeding within the United States. Weaving personal stories of both the authors' and participants' milk sharing experiences and practices with theoretical analysis makes for a compelling read, albeit not hugely innovative given others', but most notably Wilson's, contributions. One distinctive observation, reinforced by the findings and analyses throughout Sharing Milk, is the dichotomy between milk sharing communities displaying "hyperadherence to recommendations by AAP and other public health agencies to feed babies breastmilk rather than formula" (p. 22), while at the same time violating these very same organizations' prohibitive stance against the practice. While public health organizations may only value human milk under certain circumstances, both donors and recipients in Sharing Milk believe in the "biovalue" of expressed human milk. Carter and Reyes-Foster describe donors for whom "giving milk becomes hero work" (p. 51) and recipients who "cherish the gifts obtained" (p. 51). "Bio-intimacy" is built through the sharing of biological material between individuals; "emotional materiality" is created through the labor of producing and obtaining the milk. Sharing is seen as "antithetical to selling" (p. 50); the intimate, emotive value of milk is lost when a profit motive is introduced and "the sacred object [human milk] is contaminated and becomes profane" (p. 53). Shared community norms (like the rejection of the monetary commodification of milk) and common practices (like meeting face-to-face), together with the inherent creation of bio-intimacy, results in milk sharing bio-communities of practice. Sharing Milk once again demonstrates that the practices of milk sharing bio-communities does not follow the alarmist imaginings of the media and public health organizations. If there can only be one takeaway from this book, it ought to be Carter and Reyes-Foster's concluding suggestion for "clarity and consistency in public health recommendations" (p. 172): if human milk is optimal nutrition, then public health organizations need to embrace milk sharing and provide guidance on risk reduction as has, for example, the Academy of Breastfeeding Medicine (Sriraman et al., 2018). If, however, infant formula is more beneficial than informally-shared human milk, then "this message needs to be conveyed and publicized in ways that are clear, consistent and evidenced-based" (p. 172).


This paper summarizes the development and implementation history of the Surveyor mobile robotic device from November 1985 through August 1986. This two-tracked remotely controlled tetherless device is used to conduct surveillance and inspection and light maintenance missions in nuclear power plants. Surveyor's relatively light weight (<400 lb) can easily be transported manually from location to location. The total maximum payload of the device, which is able to climb 40-deg stairs, is up to 300 lb when transported on a level floor. Surveyor can traverse through 14 in. of water and over 9-in.-high obstacles. Standard accessories include radiation detector, humidity monitor, temperature measurement, sound detection and position/ranging, and a standard video or CCD camera having a wide angle and telephoto lens. These devices are mounted on a 3 degree-of-freedom articulated arm with halogen lights.


A DFT (B3LYP) with basis sets 6-31G, 6-31+G*, 6-311++G** and cc-pVTZ were incorporated to study tetrazole and its substituted tautomers. The results predict 2H-tautomer to be more energetic over 1H-tautomer. E1H–2H between unsubstituted tautomers compares fairly well with experimental value, 6.95 ± 1.50 kJ mol . Activation barrier for all the species were predicted as 60.0±6.0kcal mol. Geometry based degree of aromaticity show 62.38 to 98.35 for ground state and -99.0 to 79.17 for transition state isomers.


We describe several speaker-independent speech recognition studies conducted with both landline and cellular network telephone data. The cellular environment included the three dominant standards found in the United States: CDMA, TDMA and GSM. Our goal was to design a system that operated over all these four channels, handling their innate variations, such as those of background and line characteristics. Our baseline system was trained on 200 hours of landline telephone speech from about 25,000 speakers. We experimented with MAP adaptation utilizing some training sentences from our cellular and landline databases. We applied an LDA procedure to improve our performance. We compared the performances of these systems on several independent test databases and demonstrated the e(cid:11)ectiveness of a hybrid system built with data taken from all four networks.


The effect of 2.2 MeV electron irradiation and subsequent annealing on the extrinsic emission peaked at hvm (77 K) near 1.37 eV (due to radiative electronic transitions in VAsZnGa pairs) in zinc-doped p-type GaAs is studied. Non-trivial non-monotonic changes in the 1.37 eV emission intensities are found. An analysis of the dependences obtained shows that following one after another processes of annealing-induced (at moderate heating temperatures) increase in the concentration of the 1.37 eV radiative centres (resulting from interaction of radiation-induced arsenic vacancies VAs with substitutional zinc atoms ZnGa) and annealing-induced (at elevated heating temperatures) decrease in the amount of 1.37 eV radiative centres (resulting from radiation-induced decrease of the thermal stability of VAsZnGa pairs), may well account for the 1.37 eV emission intensity variations observed in electron-irradiated and subsequently annealed p-type GaAs(2n) crystals.

Over the last thirty years a substantial body of historical writing has evolved which deals in one way or another with the nature and tendencies of feudal economy. From the shorter conjuncture‐studies published in Annales, the regional monographs sponsored in France, the monographic estate‐studies popular in England, to the more concentrated historical synopses based on them, this literature1 covers a vast field, geographically and chronologically—sufficiently broad, in fact, to stimulate the recent tendency of historical writing to explore the character of feudal economy at a deeper level of abstraction. Kula's study [1970] stands today as the major forerunner of this tendency. Based largely on Kula's book, this short essay sketches a framework within which it becomes possible to explore more concretely the connections between commodity‐economy and feudal production, and the specific historical relationships between the enterprises of feudal production and the peasantry.2


FROM an academic viewpoint, the outpatient department of a typical teaching hospital has not been "where the action is". It has functioned under a formidable list of handicaps. Its patients have generally been medically in¬ digent, without reasonable alternative sources of medical care, and have presented themselves in large numbers. A teaching hospital cannot ignore service to patients. Indeed, it must be prepared to give exemplary service, because the reason for its existence is to teach undergradu¬ ate and graduate students of medicine to provide such service. But if a teaching hospital, or a part of a teaching hospital, is service-oriented to the extent that it cannot control the number of patients within the limits its teachers consider optimal for educational purposes, the institution is doomed from the start. There have also been other difficulties. The outpatient department was apt to have insufficient money to provide optimal care for its patients, and in making the best possible compromises to provide maximal service to the most patients for the least money, it almost inevitably created an unpleasant and crowded environment. This repelled the patient and discouraged and frustrated even the most dedicated clinical teacher and his students. Cer¬ tainly the clinical teacher could scarcely make the outpatient clinic his base of operations, for he was unlikely to bring his private patients there. All in all, it is fair to say that an outpatient teaching appointment has not been regarded as an academic plum; and the embryo academic physician or surgeon might be forgiven if he looked upon such an appointment as a bit of white water he had to shoot before he could reach the quiet, deep and academically satisfying waters of an in-patient service of his own. Inevitably, some secondary problems, which


There is a wide consensus, that it takes 10 000 hours of deliberate practice to achieve mastery, however this long road is not easy to follow. Self-regulation, co-regulation and musical agency are important aspects of deliberate practice, and as these concepts are budding in the beginner student it is important to investigate how they affect the early stages of practicing. This study aims to deepen the understanding of how self-regulation, co-regulation and musical agency influences an eight year old piano student's practicing. This study was conducted as a single case study using video recorded practising sessions and the findings are presented as a synthesis of the data building on the theoretical framework of G. McPherson and J. Renwick (2001). The results suggest that the developing musical agency of the student supports her negotiations of self-regulation, but can be a hindrance in a co-regulated environment. Keywords: piano teaching, musical practice, musical agency, self-regulation, co-regulation, zone of proximal development


Mobile Ad-hoc Networks (MANETS) are particularly useful and well-suited for critical scenarios, including military, law enforcement as well as emergency rescue and disaster recovery. An unobservable secure hybrid routing protocol (USHR) scheme achieves content unobservability by employing anonymous key establishment based on group signature for improving the performance of a routing protocol in terms of packet delivery ratio (PDR) is proposed in this paper. USHR is efficient it uses a novel combination of group signature and ID-based encryption for route discovery. The main objective of this work is to develop a privacy preserving routing protocol scheme that consumes low network delay, minimum packet loss, and maximize the network capacity. By implementing a USHR protocol using advanced hashing technique in NS2 and designed by using spread spectrum technique, the performance of USHR Protocol is improved and the same is proved through NS2 simulation compared with USOR protocol. Due to incomplete content protection complete unlinkability and unobservability are not guaranteed. The simulation results show that USHR not only has performance compared to USOR, and also achieves stronger privacy protection than existing schemes like USOR.


The invention relates to a reliable message transmission method for a distributed message system. The reliable message transmission method is mainly used for message transmission from the head quarter end to branch ends under a two-stage distributive deployment mode, message transmission from the branch ends to the head quarter end, and message transmission among different branch ends. The procedures of message transmission from the branch ends to the head quarter end are as follows: a message is sent to the service buses of branches by business servers of the branches; the service buses of branches send the message to message queue managers of the branches; the message queue managers of the branches send the message to the message queue manager of the head quarter; the message queue manager of the head quarter sends the message to the service bus of the head quarter; and the service bus of the head quarter sends the message to the business server of the head quarter. Through information transmission based on a message queue mechanism, data can not be lost or repeat during data transmission on an unstable date line.

The field experiment consisted of two crops geometry (S1-90 X 60 cm and S2-60 X 60 cm), three cotton hybrids (V1-MLCH-318, V2-VBCH-2231 and PKV Hy-2) and three levels of NPK (F1-37.5: 18.75: 18.75, F2-50: 25:25 and F3-62.5: 31.25: 31.25 kg N: P2O5:K2O/ha). Closer crop geometry of 60 X 60 cm significantly produced more plants population (271.51' 00′/ha and 242.77' 00′/ha at initial and harvest, respectively), lint yield (345 kg/ha). seed cotton yield (910 kg/ha) and stalk yield (1058 kg/ha) with uptake of N (40.39), P (14.78) and K (46.59 kg/ha) over wider crop geometry of 90 x 60 cm (S1 Among hybrids, MLCH-318 (V1) showed significantly superiority to VBCH-2231 (V2) and PKV Hy-2 (V) in respect of lint yield (407 kg/ha), seed cotton yield (1034 kg/ha) and stalk yield (1054 kg/ha). MLCH-318 (V1) when sown at crop geometry of 60 x 60 cm recorded the highest uptake of N (41.47 and 40.39), P (15.08 and 14.78) and K(48.01 and 46.59 kg/ha) with total uptake of NPK (104.56 and 101.76 kg/ha), respectively. The application of 62.5:31.25:31.25 N: P2O5: Kp/ha produced the maximum lint yield (393 kg/ha), seed cotton yield (972 kg/ha). stalk yield (988 kg/ha) and recorded higher uptake of N (40.33), P (15.08), K(46.81 kg/ha) and total uptake of NPK (102.22 kg/ha). The interaction effect between hybrids and crop geometries was found significant.


The purpose of this paper is to illustrate the performance advantages and cost savings that a silicon carbide (SiC) six-pack MOSFET module can bring to variable speed motor drives. Motor drive inverters represent just one of the many hard switched topologies that can benefit from SiC MOSFETs and diodes. In this paper, the performance of a SiC six-pack MOSFET module based motor drive inverter will be compared with an equivalent silicon (Si) six-pack IGBT module (same physical package) based motor drive inverter operating under the same conditions. The cost benefits of using the SiC module will be explored as well as potential concerns due to increased dv/dt will be discussed.


A new quasi resonant DC link that allows for pulse-width-modulation (PWM) is presented in this paper. The proposed quasi resonant DC link provides zero-voltage switching (ZVS) condition for the main devices by resonating the DC-link voltage to zero via three auxiliary switches and LC components. The operating principle and mode analysis are given. The simulation was carried out to verify the proposed soft switching technique. A 150W 120VAC single-phase prototype was built. The experimental results show that the soft switching for four main switches can be realized under different load conditions and the peak efficiency can reach 95.6%.The proposed quasi DC link can be applied to both single-phase and three-phase DC/AC micro inverter.


Advance control employed in microturbine generation system (MTGS) is expected to improve its performance in responding to grid faults. This paper compares the effect of advance control of MTGS power conversion topology on the performance in riding through the grid faults. The analysis and investigation study through simulation shows there is no significant different on MTGS output performance even advance control is employed for its rectifier.


Dr P. McLean asked what were my ideas on the possible intracellular distribution of the two fatty-acid synthesizing systems that I had postulated and also what I thought of the recent work from Gurin's laboratory, showing the solubilization of certain mitochondrial enzymes (concerned in fatty-acid synthesis) which occurs in the presence, but not in the absence, of phosphate buffer. In reply, I would say that my immediate and superficial impression is that the DPNH-utilizing system is located in the soluble fraction of the cell (obtained by centrifugation at 100000 x g for 1 h), whilst the TPNH-utilizing system is located in the microsomes. There appears to be no TPNH-utilizing system located in the soluble fraction.
