According to Yvette Hutchison, in her book South African Performance and Archives of Memory, South Africans have been engaged in a process of "formulating their sense of themselves" (2) ever since the "moment of rupture" (22) that was Nelson Mandela's release from prison, in 1990, and the inauguration of a new democratic state, in 1994. Her wide-ranging study examines several discrete performances of memory in South Africa, over the past two decades, which have responded to, or been framed by, the Truth and Reconciliation Commission (TRC). Hutchison explores several state-sanctioned performances of the nation – the TRC, the Timbuktu Script Project, the 2010 World Cup, and two museum spaces, the Voortrekker Monument and Freedom Park – as well as numerous plays. Her first chapter, "The TRC's Refiguring of the Past: Remembering and Forgetting," reads the TRC as performance. She begins by examining the "backstage" efforts at framing the national narrative of this "state-of-thenation-play" (46) and the screening process that shaped the scripts that were to be included in the public performances of the hearings themselves. This process determined the stories selected for public performance, the choice of English as the language of expression, and the religious overtones of the TRC. Next, Hutchison examines the non-verbal, gestural language of the various testimonies, including its "cries, sighs, gestures and silences" (31). Drawing on Christine Delbo's notion of "deep" memory and Elaine Scarry's theorizing of silence, Hutchison argues that these performances demonstrate how traumatic memories manifest themselves. She also asserts that the abuses of women, particularly instances of sexual violation, were highlighted by what she calls "iconic macro truths" (45), narratives of abuse and violation and images of wailing mothers and wives that the TRC ultimately wrote into South African history and made iconic. Chapter two, "Dramatising the TRC: The Role of Theatre Practitioners in Exploring the Past," examines several artistic responses to the TRC, including Jane Taylor's Ubu and the Truth Commission (1996), directed by William Kentridge and produced by the Handspring Puppet Company; the Khulamani Support Group's The Story I Am about to Tell (1998); Philip Miller's REwind: A Cantata for Voice, Tape and Testimony (2006); the ongoing Truth in Translation project (2006-present); and three contemporary plays:


Fundamental bosonic fields of arbitrary spin are predicted by generic extensions of the Standard Model and of General Relativity, and are well-motivated candidates to explain the dark components of the Universe. One of most promising channels to look for their presence is through their gravitational interaction with compact objects. Within this context, in this thesis I study several mechanisms by which bosonic fields may affect the dynamics and structure of black holes and neutron stars. The first part of the thesis is devoted to the study of massive spin-2 fields around spherically symmetric black-hole spacetimes. Massive spin-2 fields can be consistently described within theories of massive gravity, making it possible to perform a systematic study of the propagation of these fields in curved spacetimes. In particular, I show that due to the presence of additional degrees of freedom in these theories, the structure of black-hole solutions is richer than in General Relativity. In the second part of the thesis, I discuss in detail superradiant instabilities in the context of black-hole physics. I show that several mechanisms, such as massive bosonic fields and magnetic fields, can turn spinning black holes unstable against superradiant modes, which has important implications for astrophysics and for physics beyond the Standard Model. In the last part of this thesis, I present a study of how bosonic dark matter condensates interact gravitationally with compact stars. In particular, I show that stable stellar configurations formed by a perfect fluid and a bosonic condensate exist and can describe the late stages of dark matter accretion onto stars, in dark matter rich environments.


The dissolution of alumina in cryolite melts was studied in a laboratory apparatus intended to simulate the conditions in industrial cells with point feeding. Rapid dissolution is achieved if (1) a large proportion of the batch of alumina added is dispersed in the bath upon addition, and (2) the agglomerates which form, disintegrate quickly. Bubbling of gas through the melt increased the dissolution rate by promoting the dispersion of alumina grains as well as breaking up the agglomerates. Preheating of the alumina also resulted in faster dissolution, mainly due to effective dispersion of the alumina grains. High superheat of the bath enhanced the dissolution rate of the agglomerates. Measurements on a point fed industrial cell showed that the dissolution rate of the alumina decreased when the feeding hole was plugged compared to the situation when the feeding hole stayed open.


Gravity waves (GWs) have temporally and spatially small scales. Observations of GWs have been limited especially in the polar region due to its harsh environment. The purpose of this study is to elucidate the statistical characteristics of GWs in the Antarctic troposphere and lower stratosphere based on the continuous data over a year from 1 October 2015 to 30 September 2016 using the full system of the Program of the Antarctic Syowa MST/IS Radar (PANSY) radar at Syowa Station (69.0°S, 39.6°E). Such continuous observations over a long duration are unprecedented for high‐power Mesosphere‐Stratosphere‐Troposphere (MST) radars at any latitude. The frequency power spectra of horizontal wind fluctuations reveal a clear isolated maximum around the inertial frequency (f) in the lower stratosphere. A statistical analysis is performed, focusing on the GWs with near‐inertial frequencies (NIGWs) that are dominant in the lower stratosphere. According to the results of hodograph analyses, there are a considerable proportion of NIGWs propagating energy downward in the upper troposphere during all seasons, as well as in the winter stratosphere above a height of 15 km, whereas NIGWs with upward group velocities are dominant in the lower troposphere and the lowermost stratosphere. These results suggest that there are NIGW sources on the ground and around the tropopause during all seasons and in the stratosphere and/or above in winter. Plausible candidates for these sources are topography, the tropospheric jet, and the polar night jet. The statistical characteristics of NIGWs, such as horizontal phase velocity, provide powerful support for our inferences of wave sources.


Alignments of galaxy clusters (the Binggeli effect), as well as of galaxies themselves have long been studied both observationally and theoretically. Here, we test the influence of large-scale structures and tidal fields on the shapes and alignments of cluster-size and galaxy-size dark matter haloes. We use a high-resolution N-body simulation of a A cold dark matter (ACDM) universe, together with the results of Colberg, Krughoff & Connolly, who identified filaments connecting pairs of clusters. We find that cluster pairs connected by a filament are strongly aligned with the cluster-cluster axis, whereas unconnected ones are not. For smaller, galaxy-size haloes, there also is an alignment signal, but its strength is independent of whether the halo is part of an obvious large-scale structure. Additionally, we find no measurable dependence of galaxy halo shape on membership of a filament. We also quantify the influence of tidal fields and find that these do correlate strongly with alignments of haloes. The alignments of most haloes are thus caused by tidal fields, with cluster-size haloes being strongly aligned through the added mechanism of infall of matter from filaments.


In the paper, a fractional linear continuous control system with the Hilfer derivative is considered. An existence and uniqueness of a solution to such system is investigated. Based on the existence result, a theorem on the continuous dependence of solutions on controls to such problem is proved.


The article is focused on the issue of determining the key ideological prerequisites and means of forming social consciousness, which cultural policy is based on. The article argues that one of the means that forms the worldview of a society and individuals' activity in terms of understanding cultural policy is cultural worldview, which acts as a «mediator» and a channel of communication between the state, the scientific community and public consciousness. It has been analyzed that the most important task on the way to achieving the main goals of the state cultural policy is not only broad information about the essence of cultural policy but understanding this essence. As a result, a tendency: «cultural policy – intercultural communication, as an object of cultural policy – cultural worldview, as a means of intercultural communication» has been revealed at the present stage of socio-cultural development. Moreover, it has been substantiated that the patterns of intercultural communication reflect the relations between cultural systems, indicate their internal connections and relationships (the structure of cultural reality) and, thereby, form cultural worldview


Politicians are fighting over the position of Vice President. However, after becoming Vice President, they could not be active. The Vice President's role is only as a spare tire. Usually, he would only perform ceremonial acts. The exception was different when the Vice President was Mohammad Hata and Muhammad Jusuf Kalla. Therefore, this paper will question: What is the position of the President in the constitutional system? What is the position of the Vice President of Indonesia after the amendment of the 1945 Constitution? Furthermore, how is the role sharing between the President and Vice President of Indonesia? This research uses the library research method, using secondary data. This study uses qualitative data analysis methods in a prescriptive-analytical form. From the research, the writer found that the President is assisted by the Vice President and ministers in carrying out his duties. The President and the Vice President work in a team of a presidential institution. From time to time, the Indonesian Vice President's position has always been the same to assist the President. The Vice President will replace the President if the President is permanently unavailable or temporarily absent. With the Vice President's position who is directly elected by the people in a pair with the President, he/she is a partner, not subordinate to the President. Moreover, due to his/her capacity and support from his/her team, the Vice President must be empowered to benefit the nation and state.


Like any city, Bukhara and Samarkand are living organisms that are constantly undergoing processes of change and being enriched by them. For this reason they cannot be analysed as totalities in a general manner, but must be broken down into their three component parts: i) the building fabric, which includes the basic (residential) fabric and specialised (public and commercial) fabric; ii) movement, consisting of the routes and their hierarchical relationship to the building fabric, and iii) the nodes, or focal points, and and poles. In his essay, Heinz Gaube describes ninth century Bukhara in terms of the position of its gateways and main streets. The markets and commercial activities were concentrated to the south of the shahristan, where the caravans arrived, beyond the Narshakh-i Dar Bazar gate. The urban form of Samarkand is the result of a series of later transformations in the plan of the pre-existing spontaneous organism. Keywords: building fabric; Bukhara; Heinz Gaube; Samarkand; shahristan


Planning or design phase of the bridge construction project is often not optimal, which affects the amount of waste and unnecessary costs of the construction phase of the bridge so that the application of Value Engineering efforts could be a solution to optimize the value of the benefits while reducing costs unnecessary.  Besides, designs and models of various bridge today requires us to be able to choose a model which bridges the most suitable and appropriate to the local natural conditions. This study was conducted to determine the structure of the bridge what is the most economical but still complied with the required strength. The bridge was built with spans of 40 m and a width of 7 m is equipped with 2 (two) sidewalk on the right and left.

The paper investigates the potential of support vector machines and Gaussian process based regression approaches to model the oxygen–transfer capacity from experimental data of multiple plunging jets oxygenation systems. The results suggest the utility of both the modeling techniques in the prediction of the overall volumetric oxygen transfer coefficient (KLa) from operational parameters of multiple plunging jets oxygenation system. The correlation coefficient root mean square error and coefficient of determination values of 0.971, 0.002 and 0.945 respectively were achieved by support vector machine in comparison to values of 0.960, 0.002 and 0.920 respectively achieved by Gaussian process regression. Further, the performances of both these regression approaches in predicting the overall volumetric oxygen transfer coefficient was compared with the empirical relationship for multiple plunging jets. A comparison of results suggests that support vector machines approach works well in comparison to both empirical relationship and Gaussian process approaches, and could successfully be employed in modeling oxygen-transfer. Keywords—Oxygen-transfer, multiple plunging jets, support vector machines, Gaussian process.


Splitting tensile strength of concrete is normally low compared to compressive and flexural strength. Tensile force was used in the design of structural foamed mortar and to evaluate the shear resistance provided by concrete. This research focuses on the splitting tensile strength of foamed mortar incorporated with 7 different types of fibres used such as wood ash, pulverized fuel ash, silica fume, palm oil fuel ash, polypropylene fibre, coconut fibre and steel fibre. The findings show that the amount of fibres influences the enhancement level of the tensile strength. A high percentage of fibre can create a strong bonding between the particles of the foamed mortar, thus it is able to absorb energy to resist crack formation.

Timely initiation of complementary feeding and pattern of complementary feeding is suboptimal in India. Women in employment faces challenges for following optimum Infant and Young Child Feeding practices, which have a significant impact on growth and development of child under 2 years of age. Objective was to study challenges faced by women in employment for complementary feeding and pattern of complementary feeding in rural area. Qualitative study was conducted in rural area of Wardha district, India. Six FGDs were conducted and participants (total 39) were women in employment having child between 6-23 months and community level service providers. Women in rural area resume work early, could not practice exclusive breast feeding for six months. They initiate complementary feeding early and had inadequate awareness regarding complementary feeding. Women initiate semisolid and soft food at 4-6 months, smashed solid food at 7-9 months. Women leave their babies at mercy of the elders or sometime neighbours when they are at work. Villages do not have child care facilities or creches. All these determinants compromises complementary feeding with regards to timely and adequacy, recommended dietary diversity, safe feeding. Challenges for practicing exclusive breast feeding for 6 month, early initiation and inadequate complementary feeding adversely affect growth and development of children in rural area which may have undesired long term implication on the cognitive development. Strengthening Anganwadi program in India with more focus on children under 2 years, community baby care rooms / creches services would be useful strategy for supporting the women in employment to practice the optimum IYCF recommendations. India needs a conducive workplace policies and adequate protection by law for women in employment.


According to the condition that the equivalence of the test standard between 705 test rig and new 120 test rig,test rig simulation system is used to predict the experimental process.The release valve flux test in two kinds of test rig is simulated.The results show that the charging time of brake cylinder of flux test,the test standard of 705 test rig is faster than the new 120 test rig,there is a big range of overlap between the two standards,the qualified valves whose charging time of brake cylinder are less than 2.55 seconds in 705 test rig are not qualified in the new 120 test rig,meanwhile the qualified valves whose charging time of brake cylinder are between 3.09 and 4 seconds in new 120 test rig are not qualified in the 705 test rig.The test standards of the two kinds of test rig are not equivalence,it is essential to make some efforts to unify the test standards.This work can provide some references to unify the test standard of two kinds of test rig in the future.


The article analyzes the possibility of using non-destructive testing methods (namely thermal methods) to solve the main problems of technical diagnostics, such as: regulation of technical condition, fault localization and forecasting. Semiconductor radio-electronic equipment is selected as the object of control. It is fundamentally important to have in the object of control elements of feedback, which make it impossible to solve the problem of determining the technical condition using the methods of functional control. It is of the utmost importance that modern radio-electronic equipment is created using large integrated circuits, and defining a separate functional unit (separation of units) with changed parameters (with degradation of the state) is almost impossible. Automatic control systems are present in electronic equipment both in the form of separate systems, and as a part of other functional knots and blocks as regulating devices. In the article, on the example of the scheme of phase auto-tuning of frequency, the possibility of solving technical diagnostics problems for the class of feedback systems (automatic control systems) is considered. Using the method of self-radiation (compatible with an autonomous automated diagnostic system) allows you to automatically determine the mode of operation of the elements that are part of the feedback circuits and thus the state of the entire circuit reentrancy (object of control). The accumulation (increase) of voltage in the elements of the feedback circuits clearly indicates a deviation in the operation of the main system. This information, displayed by means of indications, allows reacting quickly to the current state of the object of control.


Since the seventies, two different currents, the "market-based approaches" and the "patrimonial management", trigger the international water policy debate and have further impacts on a local scale. The goal of this article is to analyze the theoretical turmoil generated by the recognition of water as a common heritage. We first return on the Common Pool Resources (CPR) theory and on one of its extensions: the patrimonial mediation and subsidiarity management. We will present then the main lessons learned from the Economics of Heritage. These various approaches will then be discussed and used extensively to analyze traditional and modern water management institutions in France and in the Maghreb.


Fiber Bragg gratings (FBGs) are well-known optical sensors, which have been widely used to perform temperature and strain measurements. Due to the cross-sensitivities of FBGs to both temperature and axial strain changes, using these fiber sensors for high-accuracy temperature measurements remained questionable. This paper presents an FBG sensor packaging technique that produces strain-free, multiplexable fiber temperature sensors. Using a precision CO2 laser heating process, a low-loss and mechanically robust fiber taper is formed near the FBG sensor, which relieves potential axial strain influence on FBG's temperature measurements. FBG sensors with tapered junctions were housed in a two-hole PEEK tube. The entire structure is then inserted into a thicker hollow PEEK tubing and welded in place. This design protects the fiber sensor from mechanical breakage and isolates it from external stress. This paper reports highly accurate temperature measurements from 77k to 567k. It presents a viable approach to developing multiplexable temperature sensors for cryogenic environment applications.


A series of the polysiloxane materials modified with tertiary amino groups were synthesized. FTIR, 1H NMR were used to characterize the polysiloxane structure. The emulsions of the modified polysiloxanes are prepared. Some surface properties of the polysiloxane materials with tertiary amino groups as resins were discussed. The results show that the polysiloxane materials modified with tertiary amino side chains had good flexibility and the repellency to water. With increasing the amino value of the polysiloxanes, the flexibility of the fabrics treated with the emulsion was improved. After the samples treated with the polysiloxanes, the thermal yellowing of the polysiloxane had emerged. The whiteness of fabrics treated with the polysiloxane decreased. The K/S of the yellow fabrics treated with the modified polysiloxanes had not obvious change, the K/S of the red and blue fabrics treated with the modified polysiloxanes slightly decreased. The shapes of the reflectance spectra curves of the dyed fabrics treated without and with the modified polysiloxanes had not noticeable change.


The aim of this study was to investigate the role of portal hypertension determining the severity of bleeding in portal hypertensive rats. The effects of section of branches of the ileocolic vein were studied in sham‐operated (SO), partial portal vein–ligated (PPVL), and common bile duct–ligated (CBDL) rats. The ensuing hemorrhage was compared with that caused by section of femoral vein, where the portal hypertensive factor is excluded. In PPVL rats, section of branches of increasing size (divided into fourth, third, second, and first order) resulted in increasingly severe bleeding (arterial pressure: ↓ ± 4%, ↓6 ± 12%, ↓15 ± 8%, and ↓28 ± 13%; P < .005; hematocrit ↓4 ± 2%, ↓6 ± 1%, ↓7 ± 2%, and ↓10 ± 4%; P < .005). Bleeding from first‐order branches was mild in SO, moderate in PPVL, and severe in CBDL rats, as shown by increasing changes in arterial pressure (↓3 ± 3%, ↓12 ± 16% and, ↓43 ± 23%; P < .01), hematocrit (↓4 ± 1%, ↓12 ± 2%, and ↓32 ± 19%; P < .01), and mortality (0%, 0%, and 56%; P < .001). Greater blood loss in CBDL rats was associated with higher portal pressure (16.6 ± 2.7 vs. 13.1 ± 1.1 mm Hg in PPVL; P < .01) and more prolonged bleeding time (70 ± 4 vs. 35 ± 3 seconds in PPVL; P < .001). Vessels were similarly dilated in CBDL and PPVL (0.7 ± 0.2 and 0.7 ± 0.1 vs. 0.4 ± 0.1 mm in SO; P < .05). Section of femoral vein caused equal blood loss in SO, PPVL, and CBDL rats, assessed by falls in hematocrit (↓8 ± 2%, ↓7 ± 1%, ↓8 ± 1%, respectively; NS) and by the blood loss (3.6 ± 0.7, 3.5 ± 0.9, and 3.8 ± 0.7 g; NS). The study shows that the degree of portal pressure elevation is a major determinant of the severity of portal hypertension–related bleeding in PPVL and CBDL rats.


Fractal patterns occur in neural networks and synaptic connections. Many aspects of higher education: teaching, learning, thinking, and evaluation of all three involve fractal neural networks that manifest fractal traits. Neural networks developed during acquisition of competency in teaching are comparable to the neural networks developed during acquisition of personality types, learning styles and multiple intelligences. A trait of all fractal forms is that their characterization requires multiple measures. Distinction of personality types etc., by necessity, require multiple measures, and the tools used for diagnoses, without exception, require spectra of diagnostic responses, because types are impossible to diagnose by single response items. Likewise, summative student ratings alone cannot define "good teaching," and the employment of students' responses to single questions to characterize "good teachers" represents a single-measure attempt to characterize a fractal system. To those who understand fractals, it is obvious why such practices are flawed and doomed to failure. However, less obvious is the fact that such evaluations are not simply inept, but also destructive. All learning, including the learning of teaching competency, involves both the cognitive and affective domains of the brain. Meta-analyses have already defined self-esteem and enthusiasm as essential affective attributes of successful teachers. When student satisfaction ratings become used tyrannically, the result is an attack on the positive affective attributes of teachers' minds. The result is counterproductive to teaching, learning, and even to the personal core of the individuals caught in such hapless situations. Fear is perhaps one of the greatest destroyers of faculty collegiality, creativity, and productivity. Although the students' voice must be heard and is an essential part of faculty evaluation, using ratings to the degree that they effectively vest students with the power to retain and fire faculty is a way to make faculty afraid of their own students. It's unconscionable, and no administrator who cares about educational quality will ever allow ratings to be used to that degree. Summative ratings result from a mix of cognitive and affective factors. Correlations reported between ratings and affective first impressions (thin slices) are even higher than those reported between ratings and learning performance. Thin-slices research confirms powerful, affective influence on ratings. Evaluative ratings are certainly honest expressions of student satisfaction and therefore represent one form of valuable information--one measure that becomes useful when informed by equally important multiple measures. However, students, unlike "customers," have responsibilities that go beyond paying for a product, so such satisfaction is not equivalent to "customer satisfaction." Affective influence is only slightly weaker on formative ratings, which use diagnostic items to deduce the pedagogical practices present in a class and the degree to which each is present. There is strong research evidence for benefits of particular instructional practices on both student learning and student satisfaction. This provides reasonable basis for including, as one essential multiple measure of a faculty member, a formative profile of pedagogical practices. Still, affect exerts strong influence even on items that would appear to solicit only an objective response. Summative rating of faculty by college students is an evaluative challenge—at the highest level of challenge in Bloom's 1956 taxonomy. The ability of students to do evaluative thinking rests upon their ability to use evidence and to meet a high Bloom-level challenge with a high-level thinking response on the Perry (1999) scale or one another of the related research-based taxonomies of thinking, all of which seem to be generally variations that map well to Perry's model. Students' ability to handle well the evaluative challenge in the special case of rating professors is no different from that to handle other evaluative challenges. Research confirms that this ability in undergraduates (King and Kitchener, 1994) is generally marginal. Knowledge surveys (see Case stories at http://elixr.merlot.org/) are a special kind of student ratings instrument. They constitute a direct and detailed portrayal of content learning from the viewpoint of students. They too are strongly influenced by affect, but more so by the students' feelings of their confidence to meet specific cognitive challenges addressed by particular knowledge survey items rather


A vision-based measurement system to quantify the yarn density of woven fabrics during production is presented. As an extension to an earlier developed fabric flaw detection system, the proposed framework consists of a combination of basic and custom-made image-processing techniques that allow to precisely track single wefts and warps within fabric images - in real-time. Several adaptations facilitate the measurement of density changes for plain, satin, and twill weaves. In this paper, the algorithmic framework has been evaluated in several comprehensive on-line experiments on a real-world air-jet loom and is additionally compared with three alternative methods for fabric density measurement. It proved to be precise, robust, and applicable for industrial use as it overcomes many of the existing shortcomings of current methods.

Introduction. As is well-known, the formulae (1) X = p2 q2, y = 2pq, Z = p2 + q2 (p>q; p, q mutually prime but not simultaneously odd in order to avoid repetitions) express all the integral solutions of the Pythagorean equation (2) x2 + y2= z2 Khazanov [1] has recently pointed out one more method for the derivation of these formulae. Using a generalised Fibonacci sequence, I have obtained ([2] and [3]) a formula by which all the Pythagorean number triples (i.e., Fibonacci number triples) may be found. The purpose of this note is to connect these two approaches. Khazanov's Method. Briefly, Khazanov's technique is as follows. Let (3) = x + xi, (x, x1)=1. Put


With regard to the problem of estimating the blurred direction of motion-blurred image,the degradation model of blurred image in uniform linear motion was analyzed in detail,and a method which can estimate blurred motion direction accurately in frequency domain was proposed.Firstly,the spectrum of degraded images was calculated,Laplacian of Gaussian(LoG) edge detection operator was used to detect the contour of dark stripes in spectrum;then the Radon transform was employed to find the perpendicular angle to the dark stripes;finally,according to the aspect ratio of the image to determine the relationship between the spectrum dark stripes and blur direction,the blur direction was calculated.The simulation results show that estimated results are very accurate and the estimation error of blurred direction is no more than one degree when the blur scale of degraded image varies from 7 to 30 pixels.


In this paper, properties of stationary waves of the transverse magnetic (TM) type which have two electric field components, i.e., axial and transverse ones, in a nonlinear self-focusing medium are discussed. Waves of the TM type are categorized into a solitary wave and several types of waves oscillating in the transverse plane. Analytical expressions of oscillating waves are obtained by using an asymptotic expansion and its extension for the large nonlinearity as well as the small one of the medium. A solitary wave is also discussed numerically, and some differences between the solitary waves of TE and TM types are mentioned.


The study deals with the most significant crisis in the history of Russian banking, which occurred when 49 municipal banks and 13 mutual credit societies went bankrupt from 1882–1889. Historians have explained the causes of the crisis in various ways; however, these explanations are not fully verifiable due to lack of consolidated quantitative data on operations for municipal banks and mutual credit societies. Therefore, a new quantitative data set on these credit institutions was composed for this study. Comparison of the dynamics of joint-stock commercial banks, municipal banks, and mutual credit societies for 1875–1895 revealed that the decline in municipal banks was particularly sharp and deep, and it did not correlate with the dynamics of other banking institutions. This paper proves that the municipal banks crisis was caused by the accumulation of bad loans, poor financial stability, and the lack of proper control by municipal councils and the Ministry of Finance. Overcoming of these problems launched a new phase of banking regulation and supervision in the Russian Empire, which has been underestimated in historiography. The "pushing out" of municipal banks from risky operations was necessary to protect the financial interests of the municipal self-government associated with these banks. However, the crisis also had a pronounced regional perspective because most of the bankruptcies occurred in the Central Black Earth Region, and therefore the crisis was caused by a contraction in agricultural exports due to falling prices, combined with local crop failures in the first half of the 1880s.


The agricultural industrialization is an objective request to develop the market economy in our country.It is also a valid path to push forward agriculture increasing way change.In developing process,the problem of fund shortage was still very serious,which needed to be settled as soon as possible.In this article,some thoughts to settle the problem were presented.

Purpose of this study is to investigate the role of learner readiness in enhancing transfer of training by empirically testing a moderated mediation mechanism in which learner readiness influences transfer through motivation to transfer, and this indirect impact is moderated by supervisor support.

Design/methodology/approach
The perception of trainees about the constructs considered has been captured through a survey of 250 employees of a unit of a manufacturing organization in India. For hypotheses testing, PROCESS macro developed by Hayes (2013) has been used.

Findings
Results have confirmed the significant role played by learner readiness in predicting transfer. This apart, supervisor support has been proved to moderate the indirect impact of learner readiness on transfer.

Practical implications
Trainees need to have pre-requisite knowledge to learn the content of a training programme, which would enable them to grasp such content and transfer the same subsequently to work. It is also essential that trainees are willing to attend any training voluntarily. Specific interventions may be designed for supervisors to bolster their catalytic role in training transfer.

Originality/value
An interactionist approach has been adopted by focussing on learner readiness as a less-studied trainee characteristic and supervisor support as a situational factor of transfer. This is construed as a significant contribution of this study to training literature. The potential overlap between learner readiness and motivation to transfer as trainee characteristics is seen to be neutralized by the presence of supervisor support as a moderator. Findings help in understanding how a trainee's readiness and motivation, together with supervisor's positive attitude, can enhance transfer.


Purpose

This qualitative study explores the barriers and dilemmas faced by beginning and novice mentors in post-compulsory education in the Southeast of England. It analyses critical incidents (Tripp, 2012) taken from the everyday practice of mentors who were supporting new teachers and lecturers in the Southeast of England. It categorises different types of critical incidents that mentors encountered and describes the strategies and rationales mentors used to support mentees and (indirectly) their learners and colleagues. The purpose of this paper is to explore ways in which mentors' own values, beliefs and life experiences affected their mentoring practice.

Design/methodology/approach

As part of a specialist master's-level professional development module, 21 mentors wrote about two critical incidents (Tripp, 2012) taken from their own professional experiences, which aimed to demonstrate their support for their mentee's range of complex needs. These critical incidents were written up as short case studies, which justified the rationale for their interventions and demonstrated the mentors' own professional development in mentoring. Critical incidents were used as units of analysis and categorised thematically by topic, sector and mentoring strategies used.

Findings

The research demonstrated the complex nature of decision making and the potential for professional learning within a mentoring dyad. The study of these critical incidents found that mentors most frequently cited the controversial nature of teaching observations, the mentor's role in mediating professional relationships, the importance of inculcating professional dispositions in education and the need to support new teachers so that they can use effective behaviour management strategies.

Originality/value

This study contributes to the understanding of the central importance of mentoring for professional growth within teacher education. It identifies common dilemmas that novice mentors face in post-compulsory education, justifies the rationale for their interventions and mentoring strategies and helps to identify ways in which mentors' professional development needs can be met. It demonstrates that mentoring is complex, non-linear and mediated by mentors' motivation and values.


Indoor positioning systems (IPSs) are attracting more and more attention from the academia and industry recently. Among them, approaches based on WiFi techniques are more favorable since they are built upon the WiFi infrastructures available in most indoor spaces. However, due to the bandwidth limit in mainstream WiFi systems, the IPS leveraging WiFi can hardly achieve centimeter localization accuracy under strong nonline-of-sight (NLOS) conditions which is common for indoor environment. In this paper, to achieve the centimeter-level accuracy, we present a WiFi-based IPS that exploits the frequency diversity via frequency hopping. In the offline phase, the system collects channel frequency responses (CFRs) from multiple channels and from a number of locations-of-interest. Then, the CFRs are post-processed to mitigate the synchronization errors as well as interference from other WiFi networks. Then, using bandwidth concatenation, the CFRs from multiple channels are combined into location fingerprints which are stored into a local database. During the online phase, CFRs are formulated into the location fingerprint and is compared against the fingerprints in the database via the time-reversal resonating strength (TRRS). Finally, the IPS determines the location according to the TRRS. Extensive experiment results demonstrate a perfect centimeter-level accuracy in an office environment with strong NLOS using only one pair of single-antenna WiFi devices.


Underwater treadmill training (UWTT) is a new hydrotherapy technique,with features of immersion bath,under water walking and body-weight support treadmill training.UWTT can reduce the load on legs,release spasm,improve gait,muscle atrophy and remain muscle strengthen for SCI patients.It also reduces the risk for cardiovascular disease,and incidence of postural hypotension.The present studies on UWTT are insufficient.More researches should further explore the therapeutic effects on SCI.


Abs t rac t . As several works in Machine Learning (particularly in Inductive Logic Programming) have focused on building recursive definitions from examples, this paper presents a formalization and a generalization of the BMWk methodology, which stems from program synthesis from examples, ten years ago. The framework of the proposed formalization is term rewriting. It allows to state some theoretical results on the qualitie s and limitations of the method.


Aims:  It has been suggested that schizophrenic patients are more vulnerable to stress than healthy persons, and that stressors can trigger a psychotic episode or worsen symptoms. The biological system often studied in relation to stress is the hypothalamic–pituitary–adrenal (HPA) axis, which controls the release of cortisol. We investigated whether the diurnal basal activity of the HPA axis differed between young male patients with schizophrenia and healthy controls.

An ideal e-voting system would allow users to go online, using web-browser or a phone application, enter their credentials and vote; it would also allow voters to verify their votes after election. The properties that make e-voting such a promising technology also raise potential privacy and efficiency problems. In literature, researchers have listed the requirements which an e-voting scheme must have. Many e-voting schemes have been proposed which are based on combination of cryptographic tools, however some schemes have efficiency problems, voter or election authority does a lot of processing at their end, and some do not fulfill all security requirements e.g. most lack coercion-resistance and receipt free-ness. In this paper, we propose an e-voting scheme based on blind signatures which fulfils important security requirements and is efficient too. In our scheme, voter does not generate any keys or sign anything, yet still is universally verifiable and coercion-resistant.


The invention provides a polarimetric SAR (synthetic aperture radar) sea vessel target detection method based on generalized multi-sub vision coherence. Multi-sub vision decomposition is carried out on four polarimetric channels of fully-polarimetric SAR data respectively, and a fully-polarimetric SAR multi-sub vision image set is formed; a corresponding coherence matrix is acquired by each piece of fully-polarimetric data, and a fully-polarimetric multi-sub vision image data set is formed; a fully-polarimetric SAR multi-sub vision image coherence operator is built; the coherence operator and the fully-polarimetric SAR multi-sub vision image set are used for calculating a fully-polarimetric multi-sub vision image coherence map; a cumulative distribution function for the coherence map is counted; a constant false alarm rate is set, and the cumulative distribution function for the coherence map is combined for calculating a detection threshold; the coherence map is traversed, whether each pixel value of the coherence map is larger than the detection threshold is judged, and a detection result binary image is outputted. The algorithm breaks limits of the sub vision image number, multiple sub vision images are used for enhancing the sea vessel contrast to a greater extent, and detection on a sea weak vessel target can be facilitated.


This paper examines whether firms exhibit less tax aggressiveness in order to mitigate workers' exposure to unemployment risk. We use unemployment insurance (UI) benefit laws as a proxy for unemployment risk and multiple measures of tax aggressiveness. Given that tax aggressiveness is risky and costly for the firm and its employees, we argue that high state UI benefits lower labor unemployment risk and, hence provide firms with an opportunity to exhibit more tax aggressiveness. Consistent with this hypothesis, we find a negative relation between firms' tax aggressiveness and unemployment risk. In additional analysis, we also find that the negative relation is more pronounced for firms in industries that are more labor intensive. Our results are robust to the exclusion of industries with a dispersed labor force and an alternative proxy for unemployment risk. Overall, our findings suggest that labor market frictions have implications for corporate tax policy.


Objective To survey the antibiotic resistance of Neisseria gonorrhoeae and the prevalence of PPNG and TRNG in Guangzhou. Method Minimum inhibitory concentrations(MIC)to penicillin G, tetracycline, ciprofloxacin, ceftriaxone and spectiomycin of Neisseria gonorrhoeae were determined using the agar dilution method,and β-lactamase was detected by paper iodin quantitative method. Result In 110 strains of Neisseria gonorrhoeae, 38 produced β-lactamase, and 56 showed plasmid-mediated, high-level resistance to tetracycline(TRNG). Resistant rates of ciprofloxacin and penicillin G were 96.4% and 93.6%, respectively. The MIC50 and MIC90 of cefditoren are 0.125 mg/L and 0.5 mg/L, respectively. The isolated strains were not resistant to ceftriaxone and specitinomycin. Conclusion Ceftriaxone and specitinomycin are the first choice of antibotics for gonorrhea treatment. The study showed that it is important to analyze the antibiotic resistance of Neisseriae gonorrhoeae.

The determinants of international currency received a lot of attention since the great recession. Classic literature focused on economy size and openness, but that couldn't explain why RMB remains largely national, while China is already leading in international trade. In this paper, I verified the importance of financial development for currency internationalization using SWIFT trade finance data. Then I built a two-country monetary search model, where trade takes time, and lack of commitment makes exporter and importer rely on bank-intermediated finance. The agent's currency choice is related with terms of trade, monetary policy, and financial efficiency. Optimal monetary policy differs according to currency regime. Related topic such as size effect and global imbalance is also discussed.


Previous research highlighted consumer dissatisfaction with fashion clothing products on offer. There is a lack of information about real consumers needs due to the industry standards of beauty and behaviour as well as a constant rush for innovation that feeds fashion cycles.

This research identifies the elements that will enable fashion clothing companies to become more inclusive, and aims to find a methodological relationship between the stakeholders in the fashion industry: consumers, designers and companies. The research considered the difference between a mature market as opposed to emergent ones, and addressed differences between Western and Eastern cultures.


This study looks into the politics of appearance in the retail sales labour market for women in Turkey and explores how norms of 'being presentable and fashionable' prevailing in different retail landscapes map onto intersections of class, status and the fault lines of Turkey's identity politics. In an attempt to understand how such norms are constructed, this article employs the discussion on aesthetic labour and focuses on the aesthetic labour requirements in large-scale retailers selling or competing with global brands, small-scale retailers and tesettür retailers. The article relies on data derived from participant observation, in-depth interviews and focus groups conducted with saleswomen and employers in different retail landscapes in five cities of Turkey between 2009 and 2012. The study suggests that large-scale retailers and shopping malls require retail workers to convey an appearance and deportment that fits in with globally circulating images of what is taken to be 'normal', middle class and fashionable, leading to the exclusion of saleswomen with headscarves as they are perceived to manifest a particularity and deviation from a normalized middle-class identity. On the other hand, in tesettür chain stores competing in the area of global veiling fashion, the headscarf is usually a requirement as a part of the globally relevant, Islamic middle-class image that retail workers are expected to embody. The norms of aesthetic labour in both kinds of large-scale retailers differ sharply from small-scale retailers, where embodying local gendered norms, and the ability to manage relations in local marketplaces surface as the most salient requirements from retail saleswomen.


The vegetation of southern Florida has been much neglected in serious research, although there have been numerous sketches of the country written by early travelers who concentrated on the aspects of the coastal areas accessible to visitors. Harshberger ('11, '14) has given rather general treatments of the whole southern area which are exceedingly well done considering the lack of means of travel in early times. Harper ('27) has also covered southern Florida in one of the annual reports of the Florida State Geological Survey. Harper's work is a good ecological description of the whole region of Florida south of Tampa on the west coast, and Melbourne on the east coast. It was written after new means of travel had been developed in the marshy regions of southern Florida, and he showed exceedingly keen judgment in working over this extensive region. However, a report of this sort covering such a diverse area cannot give proper emphasis to the variOtis smaller but very interesting elements of the vegetation. Other literature of the region deals with collections of newly discovered plants or popular descriptions of the tropical regions of southern flora. Ames ('04) describes many of our epiphytic orchids found in hammocks. Chapman (1878) noted many new plants as he was preparing his volume on the southern flora. Dodge (1894) and Simpson ('20, '23) have written excellent descriptions of the area from naturalists' point of view, and given information on the appearance of the country before the advent of civilization. Small ('07, '16) has written much on the region and has explored it botanically over a period of 35 years, but in all his reports there is little information of a definite character aside from lists of plants collected. The flora of southern Florida is rapidly being destroyed by advancing civilization, drainage (see last title of Literature Cited) and burning-a result of drainage. True, there have always been fires sweeping the area at various times but none like the fires of the last few years and especially of 1939.


As Paul Jay states in the opening to his 2010 volume Global Matters: The Transnational Turn in Literary Studies: 'Since the rise of critical theory in the 1970s, nothing has reshaped literary and cultural studies more than its embrace of transnationalism'.1 What the present article sets out to do is examine to what extent this (rather bold) statement holds true in the Italian context, and to analyze three further things in particular: how the trans-national, as an interpretative lens, has been employed to date in Italian cultural and literary studies; what new approaches towards the trans-national are being enacted in this field; and, finally, what the Italian case might potentially bring that is new or innovative to trans-national enquiry as a global phenomenon. On this last point, it is interesting to note the deliberate juxtaposition of the terms 'global' and 'transnational' in the title of Jay's book, and indeed, how much of his analysis necessarily engages with processes of — both economic and cultural — globalization. But as this article will go on to argue, there are significant nuances of the term trans-national, which should surely problematize such a conflation, since 'global' and 'globalized' mean very different things in cultural terms (and in different cultural contexts). And indeed, in the Italian field of literary and cultural studies, there has been a much greater use of the term 'global' ('globale', 'mondiale', or 'mondo'), primarily along the lines of a Weltliteratur model of Goethian inspiratio n, than a sustained critical engagement with the real-life processes of trans-nationalism or globalization itself. A 'world' categorization of cultural production often assumes a perspective of broad overview, or distant reading of Morettian inspiration,2 that will also become evident within the brief survey of some recent volumes on the topic in Italian cultural and literary studies which is to follow.


The eigenfrequencies of a hard‐walled acoustic cavity resonator are found by solving the Helmholtz equation with Neumann boundary conditions. A cavity C with an internal hard obstacle B of vanishing size was considered. Because the perturbation is never small in the neighborhood of the obstacle even in the limit of a small obstacle, a modified perturbation theory is required. A formalism was developed and tested by calculating the eigenfrequencies of a cylinder with an internal sphere on the axis. The results are compared with theoretical and experimental values determined by other investigators. The difference between the perturbation calculations and the numerical results varies from less than 10−5 to about 0.02 of the unperturbed eigenfrequency, depending on the size of the perturbing sphere and the mode.


The demand for maritime transport is derived primarily from the needs of industrial processes. Therefore, the boom and bust in the shipping market are typically motivated by the global economic situation. Under such an unpredictable and uncertain circumstance, for striving for a competitive position in market, explicit strategies are very significant to liner shipping companies. This paper investigates trends in liner shipping industry and analyzes the industrial structure by five forces analysis. By means of five forces analysis, competitive rivalry and barging power of buyers show a relatively strong force in liner shipping industry. At last, seven competitive strategies are proposed for liner shipping companies by taking into account of critical forces and trend in liner shipping industry.


An important step in any expansion project is obtaining an air permit. Obviously, it is quicker to obtain an air permit via the replacement of existing equipment with new modern equipment versus the building of a green-field plant. The shorter permit attainment time is generally linked to the ability to "net out" in emissions. With respect to cement plants, the term "netting out" refers to no increases in emissions of particulate, nitrogen oxides (NO/sub x/), sulfur oxides (SO/sub x/), and carbon monoxide (CO). TXI chose to evaluate the feasibility of expanding their Midlothian Cement Plant. The purpose of this paper is to discuss the permitting strategy associated with the expansion of TXI Midlothian Cement from 1.2 million stons (1.09 million mtons) of clinker to 2.8 million stons (2.5 million mtons). This permitting strategy led to the replacement of two, 900 sTPD (816 mTPD) long wet kilns with a 6,000 sTPD (5,443 mTPD) modern 4-stage preheater/precalciner kiln without an increase in emissions. In order to "net out" in particulate emissions, state of the art dust collector technology had to be used. Dust collectors for the new plant and part of the existing facility had to incorporate membrane bags in their design. In order to "net out" in sulfur emissions, a wet sulfur scrubber was considered in the design of the new kiln line. In order to "net out" in NO/sub x/ emissions, the new kiln line was installed with low NO/sub x/ calciner technology. In order to "net out" in CO emissions, a regenerative thermal oxidizer (RTO) with 95% thermal energy recovery was incorporated into the design. It is important to note that this is the first application of RTO technology in a cement plant. The general arrangement of the sulfur scrubber and the RTO is shown.


Italy is often considered as a mother country of vertical breakwaters for harbour protection, since they have been widely used all along our coasts long since. An updated location map is given in fig. 1, which also shows the position of the directional wave recording stations of the existing Italian network. The main reasons for this popularity, despite the usual availability of rock for mounds, are: the frequent favourable geotechnical conditions and large water depths (which can make them less expensive than rubble mound breakwaters), the small tidal range and not too severe wave conditions of the Mediterranean Sea (which reduce the risks of large breaking wave impact loads on the wall), a traditional familiarity since the Roman age with marine concrete structures (which are made with good pozzolan or slag cement). The most common vertical breakwaters are in fact composed by prefabricated monolithic cellular r.c. caissons, which are typically tloated and sunk with seawater ballast upon a rubble mound foundation and then filled with sand and/or concrete. They are also called "upright" or "composite" breakwaters. The present improvement of the construction technologies (also promoted by some new large projects of the offshore oil industry) ensures a high durability and low maintenance of


Topical application of sublethal but knockdown-inducing doses of Isolan® (1-isopropyl-3-methyl-5-pyrazolyl dimethylcarbamate) to house flies, Musca domestica L. resulted in substantial reduction of egg laying but did not affect mating, longevity, or egg fertility. Significant reductions in fecundity were obtained whether the insecticide was applied before or after mating and whether the insects had prior access to milk or not. Increasing the doses above the sublethal level had a greater repressing effect on fecundity but did not cause complete sterility. Thus, a sublethal dose of 0.3 μg per fly reduced total egg production by 35.8%, while doses of 0.6 and 1.0μg, representing LD10 and LD30 levels, respectively, reduced egg production by 43.1% and 77.2%, respectively. The effect of the treatments was long lasting: the daily egg production in flies treated with 0.6 μg did not equal that of the control until the 19th day after treatment; by the use of p32 milk it was found that treated flies consumed as much as 51.8% less milk than the untreated flies even 8 days after treatment.

Tests with other carbamates indicated that while pliysostigniinc and Pyrolan® (3-methyl-1-phenyl-5-pyrazolyl dimethylcarbamate) had no effect on fecundity, dimetilan, carbaryl, Bayer 39007 ( o -isopropoxyphenyl methylcarbamate) and Hercules 5727 ( m -isopropylphenyl methylcarbamate) caused significant reduction in egg production.

Although the precise nature of the interaction between the insecticide and the physiological processes that are significant in reproduction remains unresolved, the available evidence indicates that cholinestcrase inhibition is not directly responsible for the suppression of egg production.


The emergence of biodegradable pesticides as safe option has reduced the problems that result from the use of synthetic insecticides, thus creating a renewed interest in their development and use in integrated pest management of crops. The objective of this study was to investigate the insecticidal properties of the water extracts of Jatropha curcas, Vernonia amygdalina, Ageratum conyzoides, Chromolaena odorata (L) and Annona squamosa on two species of flea beetles ( Podagrica uniforma and P . sjostedti (Coleoptera : Chrysomelidae) infesting okra ( Abelmoschus esculentus (L.) Moench), variety NHAE 47-4). The leaves and seeds of the plants used in the experiment were collected from the locality, washed and shade dried. A synthetic insecticide, lambda-cyhalothrin (karate) was included in the treatments as a standard check alongside the untreated (control). The experiment was laid out in a randomized complete block design (RCBD) with seven treatments and four replicates. The efficacy of the treatments was based on reduction in flea beetles and percentage reduction in population of the pests. The results showed that only three of the plant extracts ( Jatropha curcas, Vernonia amygdalina and Annona squamosa ) significantly (P < 0.05) reduced the population of the two flea beetles at 64%, 55% and 49%, respectively. Though the other two botanicals were not significant in reducing the population of the pests, they were better than the control. All the plant extracts tested were not as effective as the synthetic insecticide in reducing flea beetles population. Among the tested plants, J. curcas , was found to be more effective, hence its use by resource poor farmers is recommended in the protection of okra against the infestation of P. uniforma and P . sjostedti .


To identify factors that are prognostic for survival in patients with stage IV malignant melanoma, a retrospective analysis was performed at the authors' institutions between 1976 and 1999. The median survival time of 53 stage IV patients was 7.1 months. Univariate analysis showed that initial site of metastasis (p=0.05) was significant prognostic factor. Conversely, the stage of disease preceding distant metastasis (p=0.59), disease free interval before distant metastasis (p=0.66), times at distant metastasis (p=0.92), and treatment modalities (p=0.17) were not significantly prognostic for survival. The response rates to DAV (dacarbazine, nimustine, vincristine), CDV (cisplatin, dacarbazine, vindesine), and DACTam (dacarbazine, nimustine, cisplatin, tarnoxifen) regimens were 22.2%, 9.1%, 0%, respectively. There was no statistically significant difference in response rates among the treatment arms (p=0.23). Although a variety of chemotherapeutic drug combinations have been explored over the years, they have not proven to be superior to dacarbazine alone. We need to develop new strategies for the treatment of stage IV melanoma. [Skin Cancer (Japan) 2001; 16: 222-227]


This paper presents numerical simulations of the convection and diffusion of heat or a contaminant released from a source in a ventilated two-dimensional room with one inlet and one or two outlets. Besides the influential factors on the air flow characteristic such as the Reynolds number ( Re ) and Grashof number ( Gr ) as well as the geometrical arrangement of the inlet and outlets, the effect of imposing boundary conditions particularly the condition at the outlet upon the air flow is studied numerically in this paper. By imposing an adequate condition for heat/contaminant on the outlet, the steady and near steady solutions of the problem are firstly computed. These solutions allow to evaluate the removal efficiency as well as show the different influence of the zero-value condition from that of the zero-flux one on the air flow characteristic. As shown in this paper, these two boundary conditions have quite different effects on the heat/mass transfer capability of the air flow.


Two Bradyrhizobium japonicum strains, TXVA and TXEA, were isolated for their desiccation tolerance and symbiotic performance with soybean as biofertilizers. Their genomes were sequenced and annotated using the Department of Energy Joint Genome Institute annotation pipeline. Sequencing yielded chromosomes of 9,193,770 and 9,339,455 bp for TXVA and TXEA, respectively.

The shortage of cadaveric organ donors continues to be a major problem for solid organ transplantation in Turkey as well as across the world. Due to this shortage, the use of marginal and expanded criteria donors has become a current issue to increase the number of transplantation and to decrease waitlist mortality rates. The use of organs of marginal donors with a history of or active central nervous system tumor has been one possible solution to increase the number of donors in organ transplantation. While this is a lifesaving practice for waitlist patients, it constitutes a risk of malignancy originating from donors. This is an important issue that should be discussed in the field of transplantation and ethics. This case study aims to discuss an ethical dilemma of liver transplantation from a donor with a history of central nervous system tumor to a patient in need of emergency liver transplantation. It is considered that the decision-making process for the use of marginal donor grafts in solid organ transplantation should be managed in accordance with ethical principles.


A broiler study was conducted for 36 days with eight treatment groups in a 2 phytase x 2 calcium (Ca) level x 2 digestible phosphorus (dP) level experimental design. Birds exposed to diets low in Ca, and standard in dP performed the best while the high Ca treatments induced negative responses, especially in the first 8 days of experimentation. It was concluded that the level of dP release from the high phytase inclusion was overestimated, while the higher Ca levels included in the study impeded phosphorus (P) digestibility and bone development.


This paper provides an analysis of various dimensions of accounting and corporate governance that have led to the currently troubling state of affairs in the financial reporting environment. Good Corporate Governance (GCG) is a mandatory requirement in today's corporate world by every stakeholder groups. Failure of giant corporate groups in the last twothree decades strengthens the demand further. And surprisingly, in some of such failures, accounting as a discipline is held liable. The way accounting is practiced or the interpretations that may give different prescriptions in similar situations are some dark areas that may open some scope for the corrupted accountants. The paper covers the concept of corporate governance, its legal framework, its current status and how accounting may be practiced to protect corporates from corruption by establishing governance. The paper analyzes how IFAC is succeeding as an international standard setter with an established place in the global financial infrastructure and it reveals a growing reliance on governance by experts together with a growth in influence of the large, multinational accounting firms. Until corporate boards are truly independent of corporate management and are knowledgeable enough to act as effective shareholder advocates, changes in accounting will be of limited impact.


The antioxidant properties of tert-butylhydroquinone (0·5 g kg−1 + 20 g kg−1 ascorbic acid—TBHQ-AS) and an extract of rosemary (2·5 g kg−1) alone and in combination were determined by their addition as solutions to cooked fish flakes stored at - 20°C. Oxidation was measured by following changes in free fatty acids, thiobarbituric acid number, fatty acid composition and sensory evaluation. The order of effectiveness in inhibiting oxidation was TBHQ-AS > combination > rosemary > untreated control −70°C > untreated control -20°C. Sensory evaluation indicated that green aroma and flavor notes were associated with the rosemary extract, while fish oil notes were associated with untreated samples.


This paper introduces the Autosub Long Range Autonomous Underwater Vehicle being developed at the National Oceanography Centre, Southampton. This propeller driven vehicle is designed to have a 6000m depth rating and a 6000km range. This is achieved by reducing the propulsion power by travelling slowly and hotel power by careful component selection and husbanding of resources. The challenges associated with net buoyancy compensation and low Reynolds number phenomena are outlined, and a passive compensation scheme is described. Early field trials are discussed, and the AUV's role in the upcoming FASTNEt science programme is outlined.


Abstract Microstructural and mechanical characteristics of Al-6Si-2Cu alloy for engine mount bracket preparedby gravity casting (as-cast) and die-casting (as-diecast) process have been investigated. For the microstructuralcharacterization, the inductively coupled plasma mass spectrometry (ICP-MS), optical microscope (OM), scan-ning electron microscope (SEM) and electron probe microanalysis (EPMA) analyses are conducted. For the inter-metallic phases, the X-ray diffraction (XRD) and energy dispersive spectroscopy (EDS) are also conducted withquantitative and qualitative analysis. Micro Vickers hardness and static tensile test are achieved in order to mea-sure mechanical properties of alloys. Secondary dendrite arm spacing (SDAS) of as-cast and as-diecast show37um and 18um, respectively. A large amount of coarsen eutectic Si, Al 2 Cu intermetallic phase and Fe-richphases are identified in the Al-6Si-2Cu alloy. Mechanical properties of gravity casting alloy are much higher thanthose of die-casting alloy. Especially, yield strength and elongation of gravity casting alloy show 2 times higher thandie-casting alloy. After shot peening, shot peening refined the surface grains and Si particles of the alloys by plasticdeformation. The surface hardness value shows that shot peening alloy has higher value than unpeening alloy.(Received September 10, 2014; Revised September 19, 2014; Accepted September 25, 2014) Key words : Lightweight automotive, Engine mount bracket, Gravity casting, Die casting, Al-Si-Cu alloy


In this paper, by using w-distances we improve and extend [Harjani, K. Sadrangani, "Fixed point theorems for weakly contractive mappings in partially ordered sets" in Ninlinear Analysis 71 (2009) 3403-3410. Mathematics Subject Classification: 47H10, 47H09


The mine gas emission rate was a parameter restricted by many factors,such as the structure in coal seam,carbonification,thickness variation and coal body structure.The coal seam structure was a leading geologic factor that controlled mine gas emission.The variation of coal seam thickness,which was attributed to different sedimentary microfacies and later tectonic movement,was of effect on the generation and preservation of coal bed methane.Particularly for the structure in coal seam,whose characters,conditions and causes of formation,failure mechanism,space patterns,scales,were of influence on mine gas emission in different degree.


Gold nanoparticles hold unique optical and electronic properties and have been extensively applied as optical and electrochemical labels for DNA and protein detection. The nanopore based analysis of gold nanoparticles will provide us good insight for further study the conjugation of nanoparticles and DNA. In the present work, we demonstrated gold nanoparticles translocation through silicon nitride (SiN) nanopore via investigation of distribution of current blockage and dwell time of gold nanoparticles with different sizes, 10 nm and 15 nm respectively. 100 mM KCl solution with 0.075% Triton X-100 and 5 mM Tris was used to avoid the aggregation of negatively charged gold nanoparticles caused by van der Waals force. Nanopore based on SiN membrane was fabricated by current dielectric breakdown technology, and the diameter of the nanopore was calculated from an empirical equation, which is 18 nm. Experimental data was analyzed via Clampfit, version 10.6.0.13, and Origin 8 (OriginLab).

Sorting algorithm is required for operating modular multilevel converter (MMC) with nearest level modulation, to keep the unbalanced submodule capacitor voltage within an acceptable range. Several sorting algorithms have been proposed in previous literatures. However, very few papers discussed about how to select the execution frequency of a sorting algorithm. This paper aims to investigate on the impact of the execution frequency in sorting algorithm on the output voltage harmonics, average switching frequency, submodule capacitor voltage fluctuation of an MMC using nearest level modulation. Multiple MMC models with different number of submodules are built in MATLAB/Simulink. Three different types of sorting algorithms are implemented, and evaluated at various execution frequencies as well as different operating points. Conclusions drawn from the extensive simulations show that to select a sorting algorithm and its execution frequency, all three performance criterions should be considered simultaneous and a minimum execution frequency is always required.


Copula method is widely used for modeling the portfolio credit risk. In this paper, we introduce a dynamic copula for CDO pricing. Because the most important parameter in CDO pricing model is the value of the portfolio loss dependent on time, so we give a dynamic estimation for portfolio loss with a random recovery. But this method cannot tell us how much the error of the loss distribution is, and then we utilize a saddle-point approximation approach to estimate the error of the loss distribution.


The purpose of this research project was to study the nucleation and growth mechanism of Zn-Co alloy electrodeposited on glassy carbon in the (reline) ChCl-Urea deep eutectic solvent, as well as its ability to inhibit the corrosion of AISI / SAE 1018 steel in a saline medium. Electrodeposit studies onto glassy carbon and 1018 steel were carried out using voltammetry and chronoamperometry techniques applying various potential steps. It was determined that the electrodeposition of the Zn-Co alloy onto the vitreous carbon is carried out by instantaneous nucleation with three-dimensional growth controlled by diffusion and that simultaneously with this process there is a reduction of the residual water present in the DES on the nuclei of the alloy formed. The kinetic constants that describe the electrodeposition process such as nucleation rate (A), number density of active sites (No) and water reduction rate constant (KWR) were determined using nucleation and growth theoretical models. The characterization of the bimetallic deposits was carried out by SEM and EDS showing branched and granular morphologies for glassy carbon and 1018 steel, respectively. In addition, alloys with high cobalt contents were obtained due to the fact that there is no anomalous co-deposition as occurs in an aqueous medium. The coatings of Zn and Zn-Co on 1018 steel obtained potentiostatically at -1.25 V and different contents of Co(II) in DES were homogeneous, adherent and covered the entire surface of the electrode. The corrosion tests were carried out using the techniques of potentiodynamic polarization curves and electrochemical impedance spectroscopy in a saline medium. It was found that the Zn and Zn-Co coatings protected the 1018 steel from corrosion by cathodic protection, in addition, the corrosion products formed were responsible for passivating the surface of the sample avoiding the rapid deterioration of the coating. The corrosion inhibition capacity increases with the cobalt content in the coatings and to a lesser extent with the electrodeposition time. The Zn-Co coating obtained at a concentration in the bath of ZnCl₂ 0.15 M + CoCl₂ 20 mM and a deposit time of 130 min presented the best behavior against corrosion with an inhibition of 98.18% that is higher than that granted by the Zn coatings (88.89%), Also, its anticorrosive properties depend on the phases of its microstructure, the electrodeposition parameters and the morphology of the corrosion products.


The aim of this study was to clarify the understanding of biological inheritance in children (ages 5, 7, 9 and 11) and adults by using a new methodological approach. In a perceptual task, participants were asked to match the photo of a newborn's face with the one of his/her mother's face, shown along with two other non-kin female faces. The non-kin female faces were either neutral, since they had no perceptual similarity to the newborn's face (control condition), or shared with the target newborn's face a salient perceptual facial feature irrelevant to kin detection, e.g., head orientation, open/closed eyes or mouth (experimental condition). Results showed that children could efficiently detect the mother's face by the age of 9 (control condition). Difficulties ignoring irrelevant salient perceptual properties occurred up to age 9 (experimental condition). We discussed whether these results could correspond to progressive conceptual changes in the understanding of inheritance.


We study the link between a previously neglected form of intangible firm asset—country reputation—and corporate sales. By exploiting variation in nationalities of foreign victims in local terror attacks, we detect unanticipated distortions in reputations of local countries in foreign countries and we pin down reductions in sales of local country firms in foreign markets. The reductions in sales are economically and statistically significant, persistent, and more pronounced after attacks with high levels of foreign media coverage. Local country firms, whose names resemble names from their countries of origin, experience greater deteriorations in their sales. The distortions in country reputations are associated with depreciations in overall firm value, sales growth, and profitability. This paper was accepted by Gustavo Manso, finance. Funding: M. I.

are nothing new ;" it is also true that a definite knowledge of these affections is comparatively new; and it is equally true that it is not very long since Mr. Lawson Tait put us in the way of treating these affections in a rational manner. Yet there was a time-not so very long ago-wheni an acute in-flammation within the pelvis was described as " pelvic peritonitis," witlhout any definite idea as to the parts involved. An attempt was made towards a more exact definition when the terms "pelvic cellulitis," " parametritis," and " perimetritis " were introduced. Now, Drs. Williams and (Chainlpnieys sneer at the new nomenclature in which " words enidinig in ' salpinx' have displaced the older and more general nilames." But this nomenclature was a .necessity, arising from a more precise knowledge, and as such needs no defence. The writers affirm that " perimetritis is probably the very commonest of all the serious diseases of women." What do they mean by " perimetritis ?" For years I have been on the look-out for a case of " pelvic cellulitis," or " parametritis," or "perimetritis," apart from an inflammatory affection of the uterine appendages, but have failed to find a solitary instance. If they mean the same as I do, then I am not disposed to contest their statement as to its frequency. But when they affirm that it is " also perfectly certain that the great majority of cases get quite well without any operation," then I join issue with tlhem, and deny the truth of the statement. A general assertion oni one side is as good as one on the other. It is, howvever, probably true that a majority of these cases lose all serious and certainly all distressing symptoms without operation. But why is it that there are so many cases of sterility in this and other countries ? The answer is-because of disease of the uterine appendages. Why are there so many one-child marriages ? Because of disease of the uterine appendages. Why are there so many cases of extrauterine gestation ? Because of disease of the uterine appendages. Hence I affirm that the great majority of cases do not get quite well, but are permanently damaged. They admit that "exceptional cases call for surgical procedures," but because some one else, whose lot it lhas been to meet with a larger number of these "exceptional cases," or who perhaps has greater skill in diagnosis, has operated more frequently, therefore lie is to be branded as indulging in wholesale mutilation. I am not concerned in defending Dr. W. Duncan, or in extricating him from a false position, for which he has only himself to thank; but I, for one, protest against being inieluded in this category, because with fewer opportunities of meeting with these cases, I operate more frequently than they. But I more especially protest against this new code of ethics by which two gentlemen, wlho " have both been in charge for many years at the obstetrical and gynrecological departments of two of the great general lhospitals of London, besides general practice;" through whose hands "during that time thousands of patients have passed," " and a very large number of cases of pelvic inflammation ;" and wlho have only "on the rarest possible occasions resorted to the removal of the appendages," venture to sit in judgment on another wlho lhas a different experience to relate, and that, too, without knowving all the details of the cases. What claim lhave they to more virtue-if less skilful in diagnosisthan others who are probably guided by the same principles, and who only operate when " after a long course of patient treatment it has seemed to them imperative to operate"? "To operate after ' a couple of months,' is, in our opinion, quite unjustifiable in chronic cases." Surely there is some confusion of ideas here. No case can be called chronic that has lasted only " a couple of months." Is a patient that has been the round of half-a-dozen general hospitals-or specialunder the care of gen-tlemen wlho lhave " for many years been in charge," etc., to be kept waiting an indefinite time in distress, and in a state of inability to earn her living, after she comes under the care of another man whlo at once recognises the exact nature of tlle case, before lie is permitted to give her that relief whlichl only a surgical operation can give her ? Humanity, at least, says No. Observe that it is not a question of disease in its acute stage that we have to do with. " Death from disease of the appendages " may be " of extreme rarity, " but total disablement is by no means rare. If the imminence of deatlh, or, as they put it, " life seemed to be threatenied," were to be takeni as the guidinig prilnciple determiiiing operation, then I sav that one-half at least of the surgical operations now being performied would be uinniecessary, if not unjustifiable. I need not particularise. " Ohl! that mine enemly would write a book! " cried the disputant of old; and behold they have done the next best thing. It was safe to deal iii generalities. But they have descended to particulars, anid have recorded their " protest against the removal of the appeindages " in certain conditions as follows:1. "Whenever a tumour of them is found, accompanied by painanid lhvemorrlhage." These were tlh( very conditionls present ill a case in whliel I operated as late as Saturday lastnot after " a couple of montlhs," but after a couple of daysin the presence of a nlear relative anid the regular medical attendant. There was a tumour as large as a small cocoa-nut (oil the riglit side, formned by a collectioni of bloody fluid ill the tube (whether a hematosalpinx or tulbal gestationi is lnot yet determinied), whllich was fused witlh the ovary. There was pain also occurring at intervals, and there was helmorhage, colntinuiiig for several weeks. Yet the symptomis (lid n-ot exten(l over six weeks. Shouild I not have beeiin held to blanie if I had refused to operate ill suclh a case? I can affirm that the gelntleman to wholm I have referredlheldime thoroughly justified. 2. " A dilated tube." A dilated tuLbe iiust contain pus or blood, or a more or less bland and( innocuous fluid, or an ovum, or it may evemi be affected wvitlh malignant disease (papilloma). Aniyone who reftuses to operate ill either of these coniditions, accompanied 1 y symptoms denlanding relief, even though "life" may llot seem to be inmmiiedliately "thireatened," is, in my opiniioin, uniwortlhy of the confidence of his patient. 3. " Affectioins of the tubes, wvith tenider or enlarged ovaries after treatment lhas beeni tried for a couple of ilontlls." AWhlo does operate under suceh circumstances ? 4. "XX hell a woman suffers froli pelvic pain or dysniienorrhoe, or dyspareunia, after one or more attacks of pelvic inHammiation. " Here it is entirely a question of the amoulit of suffering aiid the circumstances of the patient. 5. " In cases of ill-developed ovaries wvitlh anteflexioii anid dysmenorrhnica." Is this a recogllisecd pathological conditioni? I have never met witlh suC1a case. 6. "Il1 cases of cardiac dysplnca,; or 7. "Of tubercular disease of the tubes associated wvitli similar disease of otller organs ;" or 8. "IIn neurotic women withoutt disease of the cippendages." Are the writers really serious ? I trust not. But I will enumerate tlle conditionis in whiichl it is tlle duty of tile surgeon-liot of the obstetric plhysiciani-to interfere. In cases of pyosalpiix, of h1ematosalpiux, of tubal gestation, in the outer part of tlle tube, if he can dianiiose it; of lhydrosalpinx, when the sufferings of tlhe patient demand relief, witlhout reference to the questioni of duration; of papillomatous disease of the tube; of clhronlic ovaritis, wlhere prolonged treatment-over many months--has failed to give relief to urgent symptoms; of cirrlhosis of tlhe ovaries under simiiilar conditions; of dermoid tumours of the ovary of small size. If tlle surgeon be guided by tile princliples I have laid dowii and if lie be very careful to explaini to the patient aii(l ler nearest relative ill all suclh cases, the exact nature of the operation and the issues it involves, lie wvould fear neitiler "legal proceedillgs" iior thlat thie subject slhould "form the object of legislation."-I am, etc., Granville Place, AV.

This paper discusses patterns of public health misinformation observed during infectious disease epidemics. Specifically we group epidemic-related misinformation into four categories: transmission, prevention, treatment, and vaccination. By developing tools, algorithms, and other resources around these categories, institutions, companies, and individuals can proactively limit and counter the spread of misinformation and its potential negative health effects.


This study synthesizes the results about how management strategies for human resources are processed at Psychosocial Care Centers, focusing on some aspects of policies for Betterment of Work Relationships in the Brazilian Health Care System. It is an exploratory study with a quantitative approach. In order to collect the data, a questionnaire was applied to workers at 3 (three) Psychosocial Care Centers. The sample was composed of 55 health care workers. The data was analyzed with the aid of SPSS-version 11.0 software. The results indicate that there persists a flexibility of work relationships, characterized by diversification of work ties and social unprotection, not to mention unfavorable work conditions, referred to by the informants of the study. In this context, it is concluded that the elaboration and/or implementation of public policies based on management of human resources in the mental health area is urged, aiming at the reversion of this situation.


Supercritical carbon dioxide (sCO2) has recently gained a lot of interest as a working fluid in different power generation applications. For concentrated solar power (CSP) applications, sCO2 provides especially interesting option if it could be used both as the heat transfer fluid (HTF) in the solar field and as the working fluid in the power conversion unit. This work presents development of a dynamic model of CSP plant concept, in which sCO2 is used for extracting the solar heat in Linear Fresnel collector field, and directly applied as the working fluid in the recuperative Brayton cycle; these both in a single flow loop. We consider the dynamic model is capable to predict the system behavior in typical operational transients in a physically plausible way. The novel concept was tested through simulation cases under different weather conditions. The results suggest that the concept can be successfully controlled and operated in the supercritical region to generate electric power during the daytime, and p...
