Taschenbuch. Condizione: Neu. Neuware -Beginning from scratch and developing the standard topics of Linear Algebra, this book is intended as a text for a first course on the subject. The goal to which this work leads is the Theorem of Hurwitz - that the only normed algebras over the real numbers are the real numbers, the complex numbers, the quaternions, and the octonions. Unique in presenting this material at an elementary level, the book stresses the complete logical development of the subject and will provide a bavuable reference for mathematicians in general.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 184 pp. Englisch.

Buch. Condizione: Neu. Neuware -During the past decade, a dramatic increase in research and clinical interest has risen in child abuse and neglect. This recent growth in awareness isdue at leastpartly to thealarmingstatisticsdocumentingthe incidence of child maltreatment. Almost one million children are re ported to be abused and neglected each year, and many experts believe that this figure underestimates the true incidence. Indeed, recentsurveys suggest that almost 1. 5 million children are the targets of domestic vio lence every year. A significantproportion of these children die as a func tion of this maltreatment, whereas theremaindersuffera variety ofshort and long-term deleterious medicaland psychosocial consequences. Child maltreatment is a universal problem that has precipitated a mobilization of effort from a variety of disciplines, including psychology, medicine, psychiatry, social work, sociology, and criminology. Particular attention has been directed toward the prevention and treatment of childabuse and neglect. Such endeavors require the screen ing of large groups in order to identify families that are at high-risk for engaging in such behavior. Delineating those characteristics that differ entiate high- from low-risk families and children is one of the obvious priorities for researchers and clinicians in the future. This book, there fore, carefully considers the status of research on risk factors of abuse and neglect in children. Adduced data undoubtedly will have practical value for subsequent intervention efforts.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 340 pp. Englisch.

Buch. Condizione: Neu. Neuware - A modern microelectronic circuit can be compared to a large construction, a large city, on a very small area. A memory chip, a DRAM, may have up to 64 million bit locations on a surface of a few square centimeters. Each new generation of integrated circuit- generations are measured by factors of four in overall complexity -requires a substantial increase in density from the current technology, added precision, a decrease of the size of geometric features, and an increase in the total usable surface. The microelectronic industry has set the trend. Ultra large funds have been invested in the construction of new plants to produce the ultra large-scale circuits with utmost precision under the most severe conditions. The decrease in feature size to submicrons -0.7 micron is quickly becoming availabl- does not only bring technological problems. New design problems arise as well. The elements from which microelectronic circuits are build, transistors and interconnects, have different shape and behave differently than before. Phenomena that could be neglected in a four micron technology, such as the non-uniformity of the doping profile in a transistor, or the mutual capacitance between two wires, now play an important role in circuit design. This situation does not make the life of the electronic designer easier: he has to take many more parasitic effects into account, up to the point that his ideal design will not function as originally planned.

Buch. Condizione: Neu. Neuware -This volume contains the Proceedings of the Special Seminar on: FRAGTALS held from October 9-15, 1988 at the Ettore Majorana Centre for Scientific Culture, Erice (Trapani), Italy. The concepts of self-similarity and scale invariance have arisen independently in several areas. One is the study of critical properites of phase transitions; another is fractal geometry, which involves the concept of (non-integer) fractal dimension. These two areas have now come together, and their methods have extended to various fields of physics. The purpose of this Seminar was to provide an overview of the recent developments in the field. Most of the contributions are theoretical, but some experimental work is also included. Du:cing the past few years two tendencies have emerged in this field: one is to realize that many phenomena can be naturally modelled by fractal structures. So one can use this concept to define simple modele and study their physical properties. The second point of view is more microscopic and tries to answer the question: why nature gives rise to fractal structures. This implies the formulation of fractal growth modele based on physical concepts and their theoretical understanding in the same sense as the Renormalization Group method has allowed to understand the critical properties of phase transitions.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 382 pp. Englisch.

Buch. Condizione: Neu. Neuware -This handbook is inspired by occasional questions from my stu dents and coworkers as to how they can obtain easily the best network functions from which they can complete their filter design projects to satisfy certain criteria. They don't need any help to design the filter. They need only the network function. It appears that this crucial step can be a bottleneck to designers. This handbook is meant to supply the information for those who need a quick answer to a simple question of this kind. There are three most useful basic standard low-pass magnitude characteristics used in filter design. These are the Butterworth, the Chebyshev, and the elliptic characteristics. The Butterworth charac teristic is maximally flat at the origin. The Chebyshev characteristic gives equal-ripple variation in the pass band. The elliptic character istic gives equal-ripple variation in both the pass band and the stop band. The Butterworth and the Chebyshev characteristics are fairly easy to use, and formulas for their parameters are widely available and fairly easy to apply. The theory and derivation of formulas for the elliptic characteristic, however, are much more difficult to handle and understand. This is chiefly because their original development made use of the Jacobian elliptic functions, which are not familiar to most electrical engineers. Although there are several other methods of developing this characteristic, such as the potential analogy, the Chebyshev rational functions, and numerical techniques, most filter designers are as unfamiliar with these methods as they are with the elliptic functions.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 308 pp. Englisch.

Buch. Condizione: Neu. Neuware -The concept of self-handicapping can be legitimately anchored in a vari ety of intellectual contexts, some old and some newer. As this volume reminds us, Alfred Adler was perhaps the first to articulate the signifi cance of various self-defeating claims and gestures for protecting the self concept. Thus the apparent paradox of 'defeat' in the interests of 'pro tection. ' More recently (but still more than 30 years ago), Heider's 'naive psychology' added attributional rhetoric to the description of self-defeat ing strategies. While predominantly cognitive in its thrust, the attribu tional approach incorporated several motivational influences-especially those involving egocentric concerns. Heider hardly violated our common sense when he suggested that people are inclined to attribute their performances in a self-serving manner: the good things I caused; the bad things were forced upon me. The notion of self-handicapping strategies, proposed by Berglas and myself a little more than a decade ago, capitalized on these homely truths while adding a particular proactive twist. We not only make ex cuses for our blunders; we plan our engagements and our situational choices so that self-protective excuses are unnecessary. In doing so, we use our attributional understanding to arrange things so that flawed and failing performances will not be interpreted in ways that threaten our self-esteem.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 316 pp. Englisch.

Buch. Condizione: Neu. Neuware - During the last ZO years great progress has been achieved in our understanding of both earth history and vertebrate evolution. The result is that climatic/tectonic events in earth history can now be placed in a more precise and global time frame, that permit their evaluation as abiotic causal factors which might trigger extinction and dispersal events in vertebrate history. Great strides have also been made in genetics and cell biology, providing new insight into phylogenetic relationships among many vertebrates. These new data, along with data on chronologie resolution of earth history, provide tests of previous interpretations regarding ancestral-descendant relationships based solely on the fossil record. It is fitting and proper that a volume on European Neogene mammal chronology is produced at this time, to ensure that new interpretations of vertebrate evolution and chronology are based on the most accurate and current data. Vertebrate paleon tologists believe that the fossil record is the only secure data for measuring the actual course and tempo of vertebrate evolution. Knowledge of the fossil record must keep pace with advances in other areas of science so that inferences on vertebrate evolu tion are accurate and meaningful.

Buch. Condizione: Neu. Neuware -Biomechanics aims to explain the mechanics oflife and living. From molecules to organisms, everything must obey the laws of mechanics. Clarification of mechanics clarifies many things. Biomechanics helps us to appreciate life. It sensitizes us to observe nature. It is a tool for design and invention of devices to improve the quality of life. It is a useful tool, a simple tool, a valuable tool, an unavoidable tool. It is a necessary part of biology and engineering. The method of biomechanics is the method of engineering, which consists of observation, experimentation, theorization, validation, and application. To understand any object, we must know its geometry and materials of construc tion, the mechanical properties of the materials involved, the governing natural laws, the mathematical formulation of specific problems and their solutions, and the results of validation. Once understood, one goes on to develop applications. In my plan to present an outline of biomechanics, I followedthe engineering approach and used three volumes. In the first volume, Biomechanics: Mechanical Properties of Living Tissues, the geometrical struc ture and the rheological properties of various materials, tissues, and organs are presented. In the second volume, Biodynamics: Circulation, the physiology of blood circulation is analyzed by the engineering method.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 590 pp. Englisch.

Taschenbuch. Condizione: Neu. This item is printed on demand - Print on Demand Titel. Neuware -This volume constitutes the proceedings of the third biennial conference of the International Society for Theoretical Psychology, held in Arnhem, the Netherlands, April 17-21, 1989. Fifty-six papers were presented during the four days of the conference, including an invited address by Professor A. D. de Groot, and seven papers composing two plenary sessions, four on the con tribution of history to theory, and three on theoretical alternatives for contem porary psychology. Of these, 46 papers are presented in the proceedings; all of which suffered editorial changes and, with the exception of the invited ad dress, were required to meet a 15 page restriction on length. The editors gratefully acknowledge John Mills, Leendert Mos, and Hank Starn for their invaluable editorial assistance. The papers included here are presented without discussants' commen taries. (Over 125 psychologists participated at the conference.) While the papers are representative of the scope of topics covered at the conference, the hours of formal and informal discussions must, unfortunately, be left to the reader's imagination. We encourage the reader to attend one of our next conferences, planned biennially, and alternately, in North America (1991) and Europe (1993).Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 488 pp. Englisch.

Buch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -In 1979, I edited Volume 18 in this series: Solution Methods for Integral Equations: Theory and Applications. Since that time, there has been an explosive growth in all aspects of the numerical solution of integral equations. By my estimate over 2000 papers on this subject have been published in the last decade, and more than 60 books on theory and applications have appeared. In particular, as can be seen in many of the chapters in this book, integral equation techniques are playing an increas ingly important role in the solution of many scientific and engineering problems. For instance, the boundary element method discussed by Atkinson in Chapter 1 is becoming an equal partner with finite element and finite difference techniques for solving many types of partial differential equations. Obviously, in one volume it would be impossible to present a complete picture of what has taken place in this area during the past ten years. Consequently, we have chosen a number of subjects in which significant advances have been made that we feel have not been covered in depth in other books. For instance, ten years ago the theory of the numerical solution of Cauchy singular equations was in its infancy. Today, as shown by Golberg and Elliott in Chapters 5 and 6, the theory of polynomial approximations is essentially complete, although many details of practical implementation remain to be worked out. 436 pp. Englisch.

Buch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -Over thirty years ago, Alfred North Whitehead wrote: 'If America is to be civilized, it has to be done (at least for the present) by the business class who are in possession of the power and the economic resources . . . . If the American universities were up to their job, they would be taking business in hand and teaching it ethics and professional standards. ' \* To the intellectual elites of his time, there was something of a minor in Whitehead's view.

Organiza tions of wealth and power have accepted their corporate social responsibili ties, and universities have launched major efforts to provide ethical instruc tion for business personnel. So far as the scholars are concerned, they quickly came to realize the difficulty of an undertaking that seeks to redefine and apply moral criteria to a very complex corporate world. Philosophers, in particular, have learned (or perhaps have relearned) how their speculations on ethics must take into account the 'living ethic' expressed in the American culture and here anthropologists, sociologists, and theologians were needed to provide an expertise that the moral manuals did not. 308 pp. Englisch.

Buch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -We would expect a successful series such as Critical Issues in American Psychiatry and the Law to present timely, relevant issues in a high-quality manner, and such is the hallmark of this outstanding series. But we might not expect the editors to dive into the especially controversial issues, e.g., ethics, and I applaud them for doing so and in such a comprehensive and thorough fashion. Public and professional concern about ethical aspects of psychiatrists' be havior and practice is growing, and exponentially. Concern about the ethical practice of modern forensic psychiatry is paralleled by deep-seated apprehen sion not only about the ethical dilemmas of psychiatry and medicine (e.g., societal versus individual patient values, the corporatization of medicine, access to versus cost of medicine) but also about the widely publicized ethical trans gressions of religious and political leaders. That's why this volume is so timely and important. Ethics-the principles and rules of right conduct. Sounds simple. We know it is not. When I'm asked by colleagues to consider the perceived unethical behavior of a fellow professional, I often find that, like obscenity, they can't always define it but they are definite that they know it when they see it. The perception of ethical conduct often appears to be in the eyes of the beholder. read this volume. It may not always please you, Well, that's why you will want to it may upset you and even offend you, but it will definitely inform you. 372 pp. Englisch.

Buch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -This book represents the proceedings of a NATO Advanced Research Workshop of the same name, held at St. Andrews University, Scotland in July of 1989. It was the first meeting of its kind and was convened as a forum to review and discuss the phylogeny of some of the cell biological functions that underlie nervous system function, such matters as intercellular communication in diverse, lower organisms, and the electrical excitability of protozoans and cnidarians, to mention but two. The rationale behind such work has not necessarily been to understand how the first nervous systems evolved; many of the animals in question provide excellent opportunities for examining general questions that are unapproachable in the more complex nervous systems of higher animals. Nevertheless, a curiosity about nervous system evolution has invariably pervaded much of the work. The return on this effort has been mixed, depending to a large extent on the usefulness of the preparation under examination. For example, work on cnidarians, to many the keystone phylum in nervous system evolution simply because they possess the 'first' nervous systems, lagged behind that carried out on protozoans, because the latter are large, single cells and, thus, far more amenable to microelectrode-based recording techniques. Furthermore, protozoans can be cultured easily and are more amenable to genetic and molecular analyses. 452 pp. Englisch.
