As the long boom of post-World War II economic expansion spread across the globe, dreams of white picket fences, democratic ideals, and endless opportunities flourished within the United States. Middle America experienced a period of affluent stability built upon a modern age of industrialization. Yet for the people of Appalachia, this new era brought economic, social, and environmental devastation, preventing many from realizing the American Dream. Some families suffered in silence; some joined a mass exodus from the mountains; while others, trapped by unemployment, poverty, illness, and injury became dependent upon welfare. As the one state most completely Appalachian, West Virginia symbolized the region's dilemma, even as it provided much of the labor and natural resources that fueled the nation's prosperity. An Appalachian Reawakening: West Virginia and the Perils of the New Machine Age, 1945-1972 recounts the difficulties the state of West Virginia faced during the post-World War II period. While documenting this turmoil, this valuable analysis also traces the efforts of the New Frontier and Great Society programs, which stimulated maximum feasible participation and lead to the ultimate rise of grass roots activities and organizations that improved life and labor in the region and undermined the notion of Appalachian fatalism.

This invaluable book, based on the many years of teaching experience of both authors, introduces the reader to the basic ideas in differential topology. Among the topics covered are smooth manifolds and maps, the structure of the tangent bundle and its associates, the calculation of real cohomology groups using differential forms (de Rham theory), and applications such as the PoincariHopf theorem relating the Euler number of a manifold and the index of a vector field. Each chapter contains exercises of varying difficulty for which solutions are provided. Special features include examples drawn from geometric manifolds in dimension 3 and Brieskorn varieties in dimensions 5 and 7, as well as detailed calculations for the cohomology groups of spheres and tori.

Elliptic cohomology is an extremely beautiful theory with both geometric and arithmetic aspects. The former is explained by the fact that the theory is a quotient of oriented cobordism localised away from 2, the latter by the fact that the coefficients coincide with a ring of modular forms. The aim of the book is to construct this cohomology theory, and evaluate it on classifying spaces BG of finite groups G. This class of spaces is important, since (using ideas borrowed from Monstrous Moonshine') it is possible to give a bundle-theoretic definition of EU-(BG). Concluding chapters also discuss variants, generalisations and potential applications.

J. Frank Adams was one of the world's leading topologists. He solved a number of celebrated problems in algebraic topology, a subject in which he initiated many of the most active areas of research. He wrote a large number of papers during the period 1955-1988, and they are characterised by elegant writing and depth of thought. Few of them have been superseded by later work. This selection, in two volumes, brings together all his major research contributions. They are organised by subject matter rather than in strict chronological order. The first contains papers on: the cobar construction, the Adams spectral sequence, higher-order cohomology operations, and the Hopf invariant one problem; applications of K-theory; generalised homology and cohomology theories. The second volume is mainly concerned with Adams' contributions to: characteristic classes and calculations in K-theory; modules over the Steenrod algebra and their Ext groups; finite H-spaces and compact Lie groups; maps between classifying spaces of compact groups. Every serious student or practitioner of algebraic topology will want to own a copy of these two volumes both as a historical record and as a source of continued reference.

Chapter 1 - Controversies in Management Chapter 2 - What is Management? A Term in Search of a Meaning Chapter 3 - What is Management? Exploitation Politics and Magic Chapter 4 - The Social Sciences: Can they help managers? Chapter 5 - Principles of Management - Valid or Vacuous? Chapter 6 - Getting Ahead in Management: Meritocracy or Myth? Chapter 7 - Gender in Management - Must Men Manage? Chapter 8 - Organizational Leadership - Does it Make a Difference? Chapter 9 - Managing all over the World - One Way or Many? Chapter 10 - The Future of Management: Business as Unusual?

As the vast literature on management has grown over the years, so too has controversy and dispute. Modern managers cope not only with a complex and ever-changing world, but also with diverse ways of understanding and managing it. This second edition of the popular Controversies in Management sets out to explore some of these puzzles and provide a guide to the different key theories and approaches to management that have developed over the years, relating them to the context of modern business as well as tracing their roots in social science. Thoroughly revised and up-to-date, this is an excellent introductory guide for students, guiding them through the main areas of debate and giving them tools with which to structure their thinking and approach.

This book provides a variety of answers in its description and discussion of new, sometimes radical approaches to usability evaluation', now an increasingly common business tool. It contains new thinking of the subject of usability evaluation in industry. Contributions come from those involved in the practice of industry-based usability evaluation as well as those involved in related research activity. The chapters are derived from and developed from presentations and discussions at the invited international seminar Usability Evaluation in Industry', and give a leading edge overview of current usability practice in industry - identifying those issues of concern and approaches to tackling these.
Key Features:
* Provides a comprehensive overview of current practice
* International examples
* Contains practical examples of ergonomics at work and gives clear ideas of what does and doesn't work under industrial constraints

This book contains a unified treatment of a class of problems of signal detection theory. This is the detection of signals in addi tive noise which is not required to have Gaussian probability den sity functions in its statistical description. For the most part the material developed here can be classified as belonging to the gen eral body of results of parametric theory. Thus the probability density functions of the observations are assumed to be known, at least to within a finite number of unknown parameters in a known functional form. Of course the focus is on noise which is not Gaussian; results for Gaussian noise in the problems treated here become special cases. The contents also form a bridge between the classical results of signal detection in Gaussian noise and those of nonparametric and robust signal detection, which are not con sidered in this book. Three canonical problems of signal detection in additive noise are covered here. These allow between them formulation of a range of specific detection problems arising in applications such as radar and sonar, binary signaling, and pattern recognition and classification. The simplest to state and perhaps the most widely studied of all is the problem of detecting a completely known deterministic signal in noise. Also considered here is the detection random non-deterministic signal in noise. Both of these situa of a tions may arise for observation processes of the low-pass type and also for processes of the band-pass type."

Non-Gaussian Signal Processing is a child of a technological push. It is evident that we are moving from an era of simple signal processing with relatively primitive electronic cir cuits to one in which digital processing systems, in a combined hardware-software configura. tion, are quite capable of implementing advanced mathematical and statistical procedures. Moreover, as these processing techniques become more sophisticated and powerful, the sharper resolution of the resulting system brings into question the classic distributional assumptions of Gaussianity for both noise and signal processes. This in turn opens the door to a fundamental reexamination of structure and inference methods for non-Gaussian sto chastic processes together with the application of such processes as models in the context of filtering, estimation, detection and signal extraction. Based on the premise that such a fun damental reexamination was timely, in 1981 the Office of Naval Research initiated a research effort in Non-Gaussian Signal Processing under the Selected Research Opportunities Program."

This book was written as a first treatment of statistical com munication theory and communication systems at a senior graduate level. The only formal prerequisite is a knowledge of ele mentary calculus; however, some familiarity with linear systems and transform theory will be helpful. Chapter 1 is introductory and contains no substantial techni cal material. Chapter 2 is an elementary introduction to probability theory at a nonrigorous and non abstract level. It is essential to the remainder of the book but may be skipped (or reviewed has tily) by any student who has taken a one-semester undergraduate course in probability. Chapter 3 is a brief treatment of random processes and spec tral analysis. It includes an introduction to shot noise (Sections 3.14-3.17) which is not subsequently used explicitly. Chapter 4 considers linear systems with random inputs. It includes a considerable amount of material on narrow-band sys tems and on the representation of random processes. Chapter 5 treats the matched filter and the linear least mean-squared-error filter at an elementary level but in some detail. Numerous examples are provided throughout the book. Many of these are of an elementary nature and are intended merely to illustrate textual material. A reasonable number of problems of varying difficulty are provided. Instructors who adopt the text for classroom use may obtain a Solutions Manual for most of the problems by writing to the author."
