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.

Thermal systems are essential features in power, chemical processing, air conditioning, and other industries where heat and power are used. As the cost and complexity of designing thermal systems have increased, the need to understand and improve the design process has also grown. This book describes recent progress in the design of thermal systems. The book begins with a brief history and outline of developments in thermal system design. Chapters then discuss computer design tools for the power and chemical industries, predicting physical properties with computational tools, the use of 'pinch analysis' to improve thermal efficiency, applications of the exergy concept, the emerging concept of thermoeconomics, and the potential for artificial intelligence and expert systems in the design of thermal systems. With chapters written by internationally recognised authorities, the book offers a state-of-the-art review for both researchers and practitioners in mechanical, aerospace, chemical,

In updating the 1988 text, Greenberg (mechanical engineering, U. of Delaware, Newark) has incorporated a computer algebra system (namely, Maple, with an instructor's manual and student supplement avai

Computational techniques have become indispensable tools in solving complex problems in transport phenomena. This book, first published in 1997, provides a clear, user-oriented introduction to the subject. Each self-contained chapter includes a detailed worked example and a discussion of the problem system equations. Also included are the numerical methods used; computer code for the solution of the problem system equations; discussion of the numerical solution with emphasis on physical interpretation; and when appropriate, a comparison of the numerical solution with an analytical solution or a discussion of how the numerical solution goes beyond what can be done analytically, especially for nonlinear problems. Intended for students and a broad range of scientists and engineers, the book includes computer code written in transportable Fortran so that readers can produce the numerical solutions and then extend them to other cases. The programs are also available on the author's web site

Information is a central topic in computer science, cognitive science and philosophy. In spite of its importance in the 'information age', there is no consensus on what information is, what makes it possible, and what it means for one medium to carry information about another. Drawing on ideas from mathematics, computer science and philosophy, this book addresses the definition and place of information in society. The authors, observing that information flow is possible only within a connected distribution system, provide a mathematically rigorous, philosophically sound foundation for a science of information. They illustrate their theory by applying it to a wide range of phenomena, from file transfer to DNA, from quantum mechanics to speech act theory.

Intelligence services form an important but controversial part of the modern state. Drawing mainly on British and American examples, this book provides an analytic framework for understanding the 'intelligence community' and assessing its value. The author, a former senior British intelligence officer, describes intelligence activities, the purposes which the system serves, and the causes and effects of its secrecy. He considers 'intelligence failure' and how organisation and management can improve the chances of success. Using parallels with the information society and the current search for efficiency in public administration as a whole, the book explores the issues involved in deciding how much intelligence is needed and discusses the kinds of management necessary. In his conclusions Michael Herman discusses intelligence's national value in the post-Cold War world. He also argues that it has important contributions to make to international security, but that its threat-inducing acti

This is the first introduction to rhythm and meter that begins where students are: as speakers of English familiar with the rhythms of ordinary spoken language, and of popular verse such as nursery rhymes, song and rap. Poetic Rhythm builds on this knowledge and experience, taking the reader from the most basic questions about the rhythms of spoken English to the elaborate achievements of past and present poets. Terminology is straightforward, the simple system of scansion that is introduced is suitable for both handwriting and computer use, and there are frequent practical exercises. Chapters deal with the elements of verse, English speech rhythms, the major types of metrical poetry, free verse, and the role of sense and syntax. Poetic Rhythm will help readers of poetry experience and enjoy its rhythms in all their power, subtlety and diversity, and will serve as an invaluable tool for those who wish to write or discuss poetry in English at a basic as well as a more advanced level.

This 1994 book develops a way of representing the meanings of linguistic expressions which is independent of any particular language, allowing the expressions to be manipulated in accordance with rules related to their meanings which could be implemented on a computer. It begins with a survey of the contributions of linguistics, logic and computer science to the problem of representation, linking each with a particular type of formal grammar. A system of graphs is then presented, organized by scope relations in which linguistic constituents are sub-graphs whose configuration is determined by their categories. In developing this system, the author extends the notion of scope and argues that anaphoric and relative pronouns are structural signs not linguistic constituents. Certain count nouns are made the basis of this system and an account of proper names relating the count nouns, is given.

This textbook explains the basic principles of categorical type theory and the techniques used to derive categorical semantics for specific type theories. It introduces the reader to ordered set theory, lattices and domains, and this material provides plenty of examples for an introduction to category theory. which covers categories, functors, natural transformations, the Yoneda lemma, cartesian closed categories, limits, adjunctions and indexed categories. Four kinds of formal system are considered in detail, namely algebraic, functional, polymorphic functional, and higher order polymorphic functional type theory. For each of these the categorical semantics are derived and results about the type systems are proved categorically. Issues of soundness and completeness are also considered. Aimed at advanced undergraduates and beginning graduates, this book will be of interest to theoretical computer scientists, logicians and mathematicians specialising in category theory.

The questions of how a large population of neurons in the brain functions, how synchronized firing of neurons is achieved, and what factors regulate how many and which neurons fire under different conditions form the central theme of this book. Using a combined experimental-theoretical approach unique in neuroscience, the authors present important techniques for the physiological reconstruction of a large biological neuronal network. They begin by discussing experimental studies of the CA3 hippocampal region in vitro, focusing on single-cell and synaptic electrophysiology, particularly the effects a single neuron exerts on its neighbours. This is followed by a description of a computer model of the system, first for individual cells then for the entire detailed network, and the model is compared with experiments under a variety of conditions. The results shed significant light into the mechanisms of epilepsy, electroencephalograms, and biological oscillations and provide an excellent t

This 1991 book was the first comprehensive study of the role of socialist countries within the international economic order. The author presents an overview of the emergence of the postwar economic order and examines the key features of three kinds of centrally planned economies. He then analyses the role of financial frameworks and the international trade system in ensuring smooth economic relations among market-type economies and he details the problems of associating typical CPEs within them. Finally Jozef van Brabant explores the possibility of reconstituting a multilateral economic order that can provide greater security, predictability, stability, and reliability in international economic relations. The Planned Economies and International Economic Organizations was written at a time when the Soviet Union and other centrally planned economies were seeking closer links with the mainstream world economy. It will therefore be of interest to governments and institutional economists as

This book is concerned with techniques for formal theorem-proving, with particular reference to Cambridge LCF (Logic for Computable Functions). Cambridge LCF is a computer program for reasoning about computation. It combines the methods of mathematical logic with domain theory, the basis of the denotational approach to specifying the meaning of program statements. Cambridge LCF is based on an earlier theorem-proving system, Edinburgh LCF, which introduced a design that gives the user flexibility to use and extend the system. A goal of this book is to explain the design, which has been adopted in several other systems. The book consists of two parts. Part I outlines the mathematical preliminaries, elementary logic and domain theory, and explains them at an intuitive level, giving reference to more advanced reading; Part II provides sufficient detail to serve as a reference manual for Cambridge LCF. It will also be a useful guide for implementors of other programs based on the LCF approa

This book was originally published in 1987, at a time when the future of a divided Germany went to the heart of East–West relations and European security. These essays examine the role of Germany in international politics, and shows how the 'German question' could continue to affect East–West relations and the politics of the Western alliance in the future. The contributors address such crucial questions as the existence, or otherwise, of a West German 'secret agenda' in its relations with the East; they ask about the relationship between the GDK and strict Soviet foreign policy interests; whether changes in Germany would lead to change in the central European system; and where West German commitment to unification would lead.

The designer of a software system, like the architect of a building, needs to be aware of the construction techniques available and to choose the ones that are the most appropriate. This book provides the implementer of software systems with a guide to 25 different techniques for the complete development processes, from system definition through design and into production. The techniques are described against a common background of the traditional development path, its activities and deliverable items. In addition the concepts of metrics and indicators are introduced as tools for both technical and managerial monitoring and control of progress and quality. The book is intended to widen the mental toolkit of system developers and their managers, and will also introduce students of computer science to the practical side of software development. With its wide-ranging treatment of the techniques available and the practical guidance it offers, it will prove an important and valuable work.

With the increasing application of software in systems, especially safety- or even life-critical systems, it is no longer sufficient for the software developer to rely solely on testing the code produced. Testing must begin with the specification of requirements, continue on the design and finally on the implemented system. This book gives guidance on how testing can be carried out at each of the stages of software development. It does this by looking at the development process from four viewpoints: that of the intended user of the system, of its designers, of its programmers, and of the manager responsible for development. The product of each stage of development is individually examined to see how it can be checked for correctness and consistency with earlier specifications. References are given to techniques available to the software developer and there are many helpful checklists. The contributors are all members of the British Computer Society's Working Group on Testing, and betwe

Labor Supply is a survey of and critical guide to recent theoretical and empirical work on labor supply models, both static and dynamic. The chapters on recent empirical studies and on dynamic models are of particular interest, because neither topic has so far been discussed in any detail in standard texts. Integrated within this survey is an extensive discussion of public policy issues relating to labor supply, including income transfer programs, such as welfare and Social Security, and the income tax system. A concluding chapter discusses secular trends in labor supply in the U.S. economy, in particular the long-run increase in female labor force participation.
