The idea that science is a blueprint for research, and imagination gives research its life and purpose inspired this comprehensive explanation of research methodology. The authors' decades of experience have revealed that research is a craft requiring judgment and creativity, not simply memorization and application of the rules of science. Whether one is conducting an intimate one-on-one interview or a large-scale examination of an entire society, human imagination and scientific principles of inquiry go hand in hand. To that end, this book emphasizes scientific method, but also acknowledges its critics. It covers a wide variety of data-collection techniques, but presents them as reinforcing rather than competing with one another, thus striking a balance between qualitative and quantitative methods. It is designed for students and instructors who want a comprehensive treatment of a variety of research techniques with special emphasis on qualitative approaches.

An interview with Andrew Davies, whose work includes Pride and Prejudice (1995) and Bleak House (2005), reveals the practical choices and challenges that face the professional writer and adaptor. The Companion as a whole provides an extensive survey of an increasingly popular field of study.

Testing matters! It can determine kids' and schools' futures. In a conference at the Mathematical Sciences Research Institute, mathematicians, maths education researchers, teachers, test developers, and policymakers gathered to work through critical issues related to mathematics assessment. They examined: the challenges of assessing student learning in ways that support instructional improvement; ethical issues related to assessment, including the impact of testing on urban and high-poverty schools; the different (and sometimes conflicting) needs of the different groups; and different frameworks, tools, and methods for assessment, comparing the kinds of information they offer about students' mathematical proficiency. This volume presents the results of the discussions. It highlights the kinds of information that different assessments can offer, including many examples of some of the best mathematics assessments worldwide.

In order to help people with a mental illness it is important to be able to understand and measure the severity of the experiences that they find distressing and disabling and which can affect their behaviour. SCAN is a form of interview, found acceptable to patients, which provides a detailed and accurate picture of 'mental state'. When analysed by computer it provides a diagnosis that is comparable wherever the system is used. The 9th edition of the Present State Examination (PSE-9) was published in 1974 and served to link the two main approaches to the description and classification of psychological problems. PSE-10/SCAN builds on the experience of extensive tests using PSE-9. It retains the main features of PSE-9 and links together the two international classification systems, ICD-10 and DSM-IV. This reference manual is a companion to the SCAN interview schedule and software. It describes the rationale and development of the system and provides a valuable introduction to its uses.

Multiple-input multiple-output (MIMO) technology constitutes a breakthrough in the design of wireless communications systems, and is already at the core of several wireless standards. Exploiting multipath scattering, MIMO techniques deliver significant performance enhancements in terms of data transmission rate and interference reduction. This 2007 book is a detailed introduction to the analysis and design of MIMO wireless systems. Beginning with an overview of MIMO technology, the authors then examine the fundamental capacity limits of MIMO systems. Transmitter design, including precoding and space-time coding, is then treated in depth, and the book closes with two chapters devoted to receiver design. Written by a team of leading experts, the book blends theoretical analysis with physical insights, and highlights a range of key design challenges. It can be used as a textbook for advanced courses on wireless communications, and will also appeal to researchers and practitioners working

Mirror neurons may hold the brain's key to social interaction - each coding not only a particular action or emotion but also the recognition of that action or emotion in others. The Mirror System Hypothesis adds an evolutionary arrow to the story - from the mirror system for hand actions, shared with monkeys and chimpanzees, to the uniquely human mirror system for language. In this accessible volume, experts from child development, computer science, linguistics, neuroscience, primatology and robotics present and analyse the mirror system and show how studies of action and language can illuminate each other. Topics discussed in the fifteen chapters include: what do chimpanzees and humans have in common? Does the human capability for language rest on brain mechanisms shared with other animals? How do human infants acquire language? What can be learned from imaging the human brain? How are sign- and spoken-language related? Will robots learn to act and speak like humans?

The aim of this book is to provide a unified exposition of the theory of symmetric designs with emphasis on recent developments. The authors cover the combinatorial aspects of the theory giving particular attention to the construction of symmetric designs and related objects. The last five chapters of the book are devoted to balanced generalized weighing matrices, decomposable symmetric designs, subdesigns of symmetric designs, non-embeddable quasi-residual designs, and Ryser designs. Most results in these chapters have never previously appeared in book form. The book concludes with a comprehensive bibliography of over 400 entries. Researchers in all areas of combinatorial designs, including coding theory and finite geometries, will find much of interest here. Detailed proofs and a large number of exercises make this book suitable as a text for an advanced course in combinatorial designs.

The B Method is a means for specifying, designing and coding software systems. The long-awaited B-Book is the standard reference for everything concerning this method. It contains the mathematical basis on which it is founded, the precise definitions of the notations used, and a large number of examples illustrating its use in practice. J.-R. Abrial, the inventor of B, has written the book in such a way that it can be used for self-study or for reference. It is in four parts, the first dealing with the mathematical foundations and the definition of the various mathematical structures that are needed to formalise software systems; special emphasis is placed on the notion of proof. The second part contains a presentation of the Generalised Substitution Language and of the Abstract Machine Notation; examples are given to show how large specifications can be constructed systematically. The next part introduces the two basic programming features of sequencing and loop. The last part covers

This book covers the fundamental principles of space-time coding for wireless communications over multiple-input multiple-output (MIMO) channels, and sets out practical coding methods for achieving the performance improvements predicted by the theory. Starting with background material on wireless communications and the capacity of MIMO channels, the book then reviews design criteria for space-time codes. A detailed treatment of the theory behind space-time block codes then leads on to an in-depth discussion of space-time trellis codes. The book continues with discussion of differential space-time modulation, BLAST and some other space-time processing methods and the final chapter addresses additional topics in space-time coding. The theory and practice sections can be used independently of each other. Written by one of the inventors of space-time block coding, this book is ideal for a graduate student familiar with the basics of digital communications, and for engineers implementing th

Computer vision is a rapidly growing field which aims to make computers 'see' as effectively as humans. In this book Dr Shapiro presents a new computer vision framework for interpreting time-varying imagery. This is an important task, since movement reveals valuable information about the environment. The fully-automated system operates on long, monocular image sequences containing multiple, independently-moving objects, and demonstrates the practical feasibility of recovering scene structure and motion in a bottom-up fashion. Real and synthetic examples are given throughout, with particular emphasis on image coding applications. Novel theory is derived in the context of the affine camera, a generalisation of the familiar scaled orthographic model. Analysis proceeds by tracking 'corner features' through successive frames and grouping the resulting trajectories into rigid objects using new clustering and outlier rejection techniques. The three-dimensional motion parameters are then compu

Wireless technology is a truly revolutionary paradigm shift, enabling multimedia communications between people and devices from any location. It also underpins exciting applications such as sensor networks, smart homes, telemedicine, and automated highways. This book provides a comprehensive introduction to the underlying theory, design techniques and analytical tools of wireless communications, focusing primarily on the core principles of wireless system design. The book begins with an overview of wireless systems and standards. The characteristics of the wireless channel are then described, including their fundamental capacity limits. Various modulation, coding, and signal processing schemes are then discussed in detail, including state-of-the-art adaptive modulation, multicarrier, spread spectrum, and multiple antenna techniques. The concluding chapters deal with multiuser communications, cellular system design, and ad-hoc network design. Design insights and tradeoffs are emphasized

The past decade has seen many advances in physical layer wireless communication theory and their implementation in wireless systems. This textbook takes a unified view of the fundamentals of wireless communication and explains the web of concepts underpinning these advances at a level accessible to an audience with a basic background in probability and digital communication. Topics covered include MIMO (multi-input, multi-output) communication, space-time coding, opportunistic communication, OFDM and CDMA. The concepts are illustrated using many examples from real wireless systems such as GSM, IS-95 (CDMA), IS-856 (1 x EV-DO), Flash OFDM and UWB (ultra-wideband). Particular emphasis is placed on the interplay between concepts and their implementation in real systems. An abundant supply of exercises and figures reinforce the material in the text. This book is intended for use on graduate courses in electrical and computer engineering and will also be of great interest to practising engi

Edward Albee, perhaps best known for his acclaimed and infamous 1960s drama Who's Afraid of Virginia Woolf?, is one of America's greatest living playwrights.

Wassily Leontief (1905–1999) was the founding father of input-output economics, for which he received the Nobel Prize in 1973. This book offers a collection of papers in memory of Leontief by his students and close colleagues. The first part, 'Reflections on Input-Output Economics', focuses upon Leontief as a person and scholar as well as his personal contributions to economics. It includes contributions by Nobel Laureate Paul A. Samuelson who shares his memories of a young Professor Leontief at Harvard and ends with the last joint interview with Wassily and his wife, to date previously unpublished. The second part, 'Perspectives of Input-Output Economics', includes theoretical and empirical research inspired by Leontief's work and offers a wide-ranging sample of the state of interindustry economics, a field Leontief founded. This is a strong collection likely to appeal to a wide range of professionals in universities, government, industry and international organizations.

Stravinsky's work spanned the major part of the twentieth century and engaged with nearly all its principal compositional developments. This Companion reflects the breadth of Stravinsky's achievement and influence in essays by leading international scholars on a wide range of topics. It is divided into three parts dealing with the contexts within which Stravinsky worked (Russian, modernist and compositional), with his key compositions (Russian, neoclassical and serial), and with the reception of his ideas (through performance, analysis and criticism). The volume concludes with an interview with the leading Dutch composer Louis Andriessen and a major re-evaluation of 'Stravinsky and Us' by Richard Taruskin.

The theory of dynamical systems is a major mathematical discipline closely intertwined with all main areas of mathematics. It has greatly stimulated research in many sciences and given rise to the vast new area variously called applied dynamics, nonlinear science, or chaos theory. This introduction for senior undergraduate and beginning graduate students of mathematics, physics, and engineering combines mathematical rigor with copious examples of important applications. It covers the central topological and probabilistic notions in dynamics ranging from Newtonian mechanics to coding theory. Readers need not be familiar with manifolds or measure theory; the only prerequisite is a basic undergraduate analysis course. The authors begin by describing the wide array of scientific and mathematical questions that dynamics can address. They then use a progression of examples to present the concepts and tools for describing asymptotic behavior in dynamical systems, gradually increasing the leve

In On Nature and Language Noam Chomsky develops his thinking on the relation between language, mind and brain, integrating current research in linguistics into the burgeoning field of neuroscience. This 2002 volume begins with a lucid introduction by the editors Adriana Belletti and Luigi Rizzi. This is followed by some of Chomsky's writings on these themes, together with a penetrating interview in which Chomsky provides the clearest and most elegant introduction to current theory available. It should make his Minimalist Program accessible to all. The volume concludes with an essay on the role of intellectuals in society and government. Nature and Language is a significant landmark in the development of linguistic theory. It will be welcomed by students and researchers in theoretical linguistics, neurolinguistics, cognitive science and politics, as well as anyone interested in the development of Chomsky's thought.

This 2002 collection of essays represents twenty-five years of work by one of the most important critics of Romanticism and Byron studies, Jerome McGann. The collection demonstrates McGann's evolution as a scholar, editor, critic, theorist, and historian. His 'General Analytic and Historical Introduction' to the collection presents a meditation on the history of his own research on Byron, in particular how scholarly editing interacted with the theoretical innovations in literary criticism over the last quarter of the twentieth century. McGann's receptiveness to dialogic forms of criticism is also illustrated in this collection, which contains an interview and concludes with a dialogue between McGann and the editor. Many of these essays have previously been available only in specialist scholarly journals. Now McGann's influential work on Byron can be appreciated more widely by new generations of students and scholars.

Few American playwrights have exerted as much influence on the contemporary stage as Sam Shepard. His plays are performed on and off Broadway and in all the major regional American theatres. They are also widely performed and studied in Europe, particularly in Britain, Germany and France, finding both a popular and scholarly audience. In this collection of seventeen original essays, American and European authors from different professional and academic backgrounds explore the various aspects of Shepard's career - his plays, poetry, music, fiction, acting, directing and film work. The volume covers the major plays, including Curse of the Starving Class, Buried Child, and True West, as well as other lesser known but vitally important works. A thorough chronology of Shepard's life and career, together with biographical chapters, a note from the legendary Joseph Chaikin, and an interview with the playwright, give a fascinating first-hand account of an exuberant and experimental personalit

Imitation guides the behaviour of a range of species. Scientific advances in the study of imitation at multiple levels from neurons to behaviour have far-reaching implications for cognitive science, neuroscience, and evolutionary and developmental psychology. This volume, first published in 2002, provides a summary of the research on imitation in both Europe and America, including work on infants, adults, and nonhuman primates, with speculations about robotics. A special feature of the book is that it provides a concrete instance of the links between developmental psychology, neuroscience, and cognitive science. It showcases how an interdisciplinary approach to imitation can illuminate long-standing problems in the brain sciences, including consciousness, self, perception-action coding, theory of mind, and intersubjectivity. The book addresses what it means to be human and how we get that way.

Ever since the seminal work of Goppa on algebraic-geometry codes, rational points on algebraic curves over finite fields have been an important research topic for algebraic geometers and coding theorists. The focus in this application of algebraic geometry to coding theory is on algebraic curves over finite fields with many rational points (relative to the genus). Recently, the authors discovered another important application of such curves, namely to the construction of low-discrepancy sequences. These sequences are needed for numerical methods in areas as diverse as computational physics and mathematical finance. This has given additional impetus to the theory of, and the search for, algebraic curves over finite fields with many rational points. This book aims to sum up the theoretical work on algebraic curves over finite fields with many rational points and to discuss the applications of such curves to algebraic coding theory and the construction of low-discrepancy sequences.

This is a detailed study of one of the most important plays in contemporary theatre, Who's Afraid of Virginia Woolf?, by Edward Albee. In this fascinating look at the modern stage, Stephen Bottoms draws on original archival material and sources including an exclusive interview with Edward Albee. The Introduction considers the text of the play itself; part one provides a survey of the major productions from 1962 to 1999, with special attention paid to the premiere and the 1966 film version. Part two examines shifting critical responses to the play, demonstrating how changing times and attitudes have altered audience perception of performances. The third and final part offers a detailed examination of five different performances, comparing and contrasting directorial, design and acting approaches to demonstrate how our understanding of the play alters considerably according to its interpretation on stage.

Just as the Bolshevik revolution defined the early politics of the 20th century, the transition from communist rule is the landmark event of its final years. In this important 1999 textbook, based on a wealth of references including interview and survey material, Stephen White offers a full, discriminating account of the dramatic process of change in what is still the world's largest country. After an early chapter examining the Gorbachev legacy, the book analyses the electoral process, the powerful presidency, and the intractable problem of economic reform. Later chapters cover social divisions, public opinion, and foreign policy, and a final chapter places the Russian experience within the wider context of democratisation. Clearly written, with numerous figures and illustrations, this book takes up Russia's story from the author's best-selling After Gorbachev to provide an unrivalled analysis of the politics of change in what is now the world's largest postcommunist society.

This is a comprehensive discussion of complexity as it arises in physical, chemical, and biological systems, as well as in mathematical models of nature. Common features of these apparently unrelated fields are emphasised and incorporated into a uniform mathematical description, with the support of a large number of detailed examples and illustrations. The quantitative study of complexity is a rapidly developing subject with special impact in the fields of physics, mathematics, information science, and biology. Because of the variety of the approaches, no comprehensive discussion has previously been attempted. This book will be of interest to graduate students and researchers in physics (nonlinear dynamics, fluid dynamics, solid-state, cellular automata, stochastic processes, statistical mechanics and thermodynamics), mathematics (dynamical systems, ergodic and probability theory), information and computer science (coding, information theory and algorithmic complexity), electrical engi

In order to help people with a mental illness it is important to be able to understand and measure the severity of the experiences that they find distressing and disabling and which can affect their behaviour. SCAN is a form of interview, found acceptable to patients, which provides a detailed and accurate picture of 'mental state'. When analysed by computer it provides a diagnosis that is comparable wherever the system is used. The 9th edition of the Present State Examination (PSE-9) was published in 1974 and served to link the two main approaches to the description and classification of psychological problems. PSE-10/SCAN builds on the experience of extensive tests using PSE-9. It retains the main features of PSE-9 and links together the two international classification systems, ICD-10 and DSM-IV. This reference manual is a companion to the SCAN interview schedule and software. It describes the rationale and development of the system and provides a valuable introduction to its uses.

The theme of volume 19 is 'Literary Devolution: Writing Now in Scotland, Wales, Ireland and England', and includes poetry from Scotland, with essays by David Kinloch and Christopher Whyte on Socttish Gaelic; and poetry from Wales with essays by Jerry Hunter and Sam Adams; from Ireland, three cantos of John Montague's new poem on David Jones, Nuala Ni Dhomhnaill's Gaelic poetry translated by Seamus Heaney, Paul Muldoon and Medbh McGuickan, and a new play by Vincent Woods, acclaimed in performance and published here for the first time; and English poetry together with new fiction by Iain Sinclair. It also includes an interview with Nathaniel Tarn, editor of innovative Cape Goliard Editions. Translation from European poets into English and Scottish is a seminal feature of poetry in this period, represented here by translation from the Polish by Seamus Heaney, from Mayakovsky by Edwin Morgan, from Rimbaud and Mandelstam by Alistair Mackie; and Sylvia Plath's translations from the French re

The diagnosis and assessment of personality disorders has lagged considerably behind that of most other mental disorders. However, the IPDE is an instrument which is compatible, through two modules, with both ICD-10 and DSM-IV criteria. In the form of a semi-structured clinical interview, it provides a means of measuring major categories of personality disorders which have been previously ignored. It is also unique in that it seeks to secure reliable and uniform diagnosis which is both internationally and cross-culturally acceptable. Written by leading international authorities, this volume forms an invaluable reference manual to the IPDE instrument and its development. Its first section includes an overview of the worldwide field trials of the interview and aspects of epidemiology which affect the current status of diagnosis and assessment research. The second section detailing the full interview schedule and scoring system for the instrument will further facilitate its use by both cl

Finite fields are algebraic structures in which there is much research interest and they have been shown to have a wide range of applications. These proceedings give a state-of-the-art account of the area of finite fields and their applications in communications (coding theory, cryptology), combinatorics, design theory, quasirandom points, algorithms and their complexity. Typically, theory and application are tightly interwoven in the survey articles and original research papers included here. These also demonstrate inter-connections with other branches of pure mathematics such as number theory, group theory and algebraic geometry. This volume is an invaluable resource for any researcher in finite fields or related areas.

The success of any interview or questionnaire depends upon good question design, yet most of the available literature has been devoted to interview techniques, rather than question formulation. This practical book provides a coherent, theoretical basis for the construction of valid and reliable questions for interviews and questionnaires. The theoretical framework used in the book provides a set of principles that, when followed, will increase the validity and reliability of verbal data collected for social research. Dr Foddy outlines the problems which can arise when framing questions with clarity and commonsense. He has written a wide ranging, useful book for survey practitioners working in the social sciences.

C is one of the most popular programming languages today. It is flexible, efficient and highly portable, and is used for writing many different kinds of programs, from compilers and assemblers to spreadsheets and games. This book is based on ANSI C - the recently adopted standard for the C language. It assumes familiarity with basic programming concepts such as variables, constants, iteration and looping, but covers all aspects of C. In general it is as much about learning programming skills as it is about mastering the art of coding programs in C. To this end the text contains a wealth of examples and exercises that foster and test the understanding of the concepts developed in each chapter. An outstanding feature of this book is a treatment of 'pointers'. The topic is presented in a clear, logical and reasoned manner that is easy to follow. Binary files and random access files are also treated in such a manner that the reader can easily become adept at using them. Anybody who wishes

Algebraic coding theory has in recent years been increasingly applied to the study of combinatorial designs. This book gives an account of many of those applications together with a thorough general introduction to both design theory and coding theory - developing the relationship between the two areas. The first half of the book contains background material in design theory, including symmetric designs and designs from affine and projective geometry, and in coding theory, coverage of most of the important classes of linear codes. In particular, the authors provide a new treatment of the Reed-Muller and generalized Reed-Muller codes. The last three chapters treat the applications of coding theory to some important classes of designs, namely finite planes, Hadamard designs and Steiner systems, in particular the Witt systems. The book is aimed at mathematicians working in either coding theory or combinatorics - or related areas of algebra. The book is, however, designed to be used by non
