Electrochemical deposition of bismuth telluride thick layers onto nickel
No full textBismuth telluride (Bi2Te3) is the currently best performing thermoelectric (TE) material in commercial TE devices for refrigeration and waste heat recovery up to 200 °C. Up to 800 ?m thick, compact, uniform and stoichiometric Bi2Te3 films were synthesized by pulsed electrodeposition from 2 M nitric acid baths containing bismuth and tellurium dioxide on 1 cm2 nickel (Ni) substrates at average film growth rates of ~ 50 ?m/h. Pre-treatment of the Ni substrate was found to significantly enhance the adhesion of Bi2Te3 material onto Ni while pulsed electrodeposition was used to increase the compactness of the material. To maintain a homogeneous composition across the thickness of the films, a sacrificial Bi2Te3 anode was employed. All deposits produced were n-type with a Seebeck coefficient of up to ? 80 ?V/K and an electrical conductivity of ~ 330 S/cm at room temperature
World Style File: Design Research and Education on a Global Scale
No full text'Style File' is a unique educational project that proposes to unite design students from around the world in an international collaborative design project, using the Internet and other electronic means of communication. It is an example of how the Internet can be used to provide students with a valuable learning experience on a global scale. The concept for “Style File” was initiated early in 2006 by Ted Polhemus – well-known “Style Commentator”, anthropologist, author, journalist and photographer. Polhemus is a widely-used consultant on youth marketing and style trends and is the author of several books on the anthropology of personal style and image. Many of these books are standard texts for design students and students of cultural studies. The author of this paper has been asked by Polhemus to monitor the progress of the students involved in the project at Liverpool John Moores University, UK, a founding participant in the project, and to provide illustrations for the book and web site that arise from the project. These illustrations will also form part of the International touring exhibition that is planned to coincide with the publication of the book in each participating country

Postfeminist authorial corpography Winona Ryder and the 1990s Woman Author Cycle
No full textThis article explores the gendering of the authorial body in Little Women (Gillian Armstrong, 1994), How to Make an American Quilt (Jocelyn Moorhouse, 1995), and Girl, Interrupted (James Mangold, 1999). As I will show, Ryder’s 1990s woman author cycle mobilises female authorship’s unruly connotations of female self-determination and autonomy, so that the Ryder figure emerges as an ideal vehicle for the enactment of feminist-inflected agency. Crucially, however, these feminist signifiers exist alongside conservative narrative trajectories which attempt to contain, contextualise, or frame the oppositional potential of this figure. Through these contradictory discursive movements, I argue, Ryder’s woman author films engage a set of sophisticated recuperative manoeuvres associated with postfeminism. In this way, this article sheds light on the hitherto overlooked ways in which the female author figure has come to function as a signifier of the contradictions and ambiguities constitutive of postfeminism, the role of Ryder’s star persona in this signification, as well as the implications of this film cycle for the broader conceptualisation of « The Author »
Proving Relative Lower Bounds for Incremental Algorithms
No full textA general powerful method that permits simple proofs of relative lower bounds for incremental update algorithms is presented. This method is applied to derive a hierarchy of relative incremental complexity. Which classifies functions by relative lower bounds. We demonstrate our technique by bounding a number of incremental algorithms drawn from various domains. The method described expands upon work by Paull, Berman, and Cheng ~71 and generalizes a result of Even and Gazit 2. Our results have interesting implications with respect to the optimality of an incremental algorithm previously developed by Ryder in [9, 101. We also show that for certain graphs, Frederickson's update algorithm for minimum spanning tree is nearly optimal. Perhaps most importantly, the proof method and hierarchy suggest which types of problems are likely to yield good incremental algorithms (i.e., of lower complexity) and which cannot be improved by an incremental approach.Technical report DCS-TR-15
Somatization vs. Psychologization of Emotional Distress: A Paradigmatic Example for Cultural Psychopathology
No full textThis paper describes the developing area of cultural psychopathology, an interdisciplinary field of study focusing on the ways in which cultural factors contribute to the experience and expression of psychological distress. We begin by outlining two approaches, often competing, in order to provide a background to some of the issues that complicate the field. The main section of the paper is devoted to a discussion of depression in Chinese culture as an example of the types of questions that can be studied. Here, we start with a review of the epidemiological literature, suggesting low rates of depression in China, and move to the most commonly cited explanation, namely that Chinese individuals with depression present this distress in a physical way. Different explanations of this phenomenon, known as somatization, are explored and reconceptualized according to an increasingly important model for cross-cultural psychologists: the cultural constitution of the self. We close by discussing some of the contributions, both theoretical and methodological, that can be made by cross-cultural psychologists to researchers in cultural psychopathology

The Financial Crisis and white collar crime ::the perfect storm? /
No full textProfessor Nicholas Ryder in The Financial Crisis and White Collar Crime: The Perfect Storm? not only provides a detailed and comprehensive chronicle of the "dark side" of the near collapse of the western financial system, but in doing so raises a number of exceedingly important issues as to the systems ability to recognise the risks presented by serious crime and its ability to address them. The extent to which fraud and abuse exacerbated the crisis is and will remain a matter for debate. What this book does, often referring to contrasting US experience, is to illustrate the serious weaknesses that existed then and perhaps remain, in the criminal justice systems' ability to bring those who commit fraud and other abuses to book. Professor Ryder has made a significant contribution not only to our understanding of what went wrong, but also in pointing to what should be done in the future.'--Professor Barry Rider, Jesus College, Cambridge. 'Nic Ryder has produced an extremely readable and carefully researched monograph. It traces a thorough and intriguing timeline through the financial crisis, incrementally building the evidence to support the link to white collar crime. Each chapter is well argued, comprehensively leading the reader towards his compelling conclusion. It promises to find its way onto the reading lists for university finance, law and criminology courses alike" - Jackie Harvey, Newcastle Business School, Northumbria University. 'Scholarly analysis of the principal causes of the global economic crash of 2008 has largely ignored any investigation of a part played by white-collar crime in precipitating the collapse. Ryder is one of the few who is not content to let the blame lie with sub-prime mortgages and the inherent risks of the markets. He enquires into the relationship between the latter-day economic chaos and crime, particularly mortgage fraud and the examination he offers is compelling. Through a distillation of massive amounts of materials drawn from two critical global financial centers, the United States and the United Kingdom, Ryder concludes, reliant on tangible empirical examples, that the prevalence of white-collar fraud was an important constituent contributor to the financial crisis.'--Michelle Gallant Ph.D, Faculty of Law, University of Manitoba. 'In this well-researched and thoughtful new book, Nic Ryder makes a strong case for thinking more about the role of white collar crime in causing the financial crisis, and why prosecution has not been a bigger part (particularly in the UK) of the authorities' responses to it.'--Peter Cartwright, School of Law, University of Nottingham. Concentrating on the relationship between the 2007 financial crisis and white-collar crime in both the United States of America and the United Kingdom this unique book asserts that such activity was an important variable that contributed towards the crisis. It also reveals a number of similarities and differences in the approach towards white-collar crime emanating from the financial crisis. Offering an important analysis of the factors which contributed to the global financial crisis and the role played by economic crime, the author provides an insightful critique of the legislative, regulatory and enforcement responses on both sides of the Atlantic. Specific examples include mortgage fraud, predatory lending, Ponzi fraud schemes, market misconduct and the manipulation of LIBOR. Nicholas Ryder's conclusions are powerful, and those responsible for policing the financial markets should take careful note of the recommendations he puts forward. This timely book will be of great use to both teachers and students of financial crime relevant modules. It will also appeal to policy-makers in government departments, law enforcement agencies and financial regulatory agencies, as well as professionals within the financial services sector, law and accountancy

A Study of Java Demographics
No full textResearchers have long strived to exploit program behaviour in order to improve garbage collection efficiency. For example, by using a simple heuristic, generational GC manages short-lived objects well, although longer-lived objects will still be promoted to an older generation and may be processed repeatedly thereafter. In this paper, we provide a detailed study of Java object lifetimes which reveals a richer landscape than the generational view offers. Allocation site has been claimed to be a good predictor for object lifetime, but we show that object lifetime can be categorised more precisely than 'short-lived/long-lived/immortal'. We show that (i) sites allocate objects with lifetimes in only a small number of narrow ranges, and (ii) sites cluster strongly with respect to the lifetime distributions of the objects they allocate. Furthermore, (iii) these clusterings are robust against the size of the input given to the program and (iv) are likely to allocate objects that are live only in particular phases of the program's execution. Finally, we show that, in contrast to previous studies, (v) allocation site alone is not always sufficient as a predictor of object lifetime distribution but one further level of stack context suffices
