Buch. Condizione: Neu. Neuware -With great pleasure I welcome you to the City of Groningen. In more than one way there is cause for celebration. Today marks the third lustrum of the annual international sympo sium on blood transfusion, organized by the Rode Kruis Bloedbank Groningen-Drenthe. In my opinion it has been a remarkable initiative of the Bloedbank, to start organizing a scientific conference, as it did, in 1976. It meant, among others, that in case of success the initiative would grow to be an annual item on the international congress calen der. It also meant that a possible third lustrum would coincide with the celebration of the 950th anniversary of the City of Groningen. I am happy to note that the initiative has been successful: over the past fourteen years the Rode Kruis Bloedbank Groningen-Drenthe has succeeded in organizing an annual symposium on blood transfusion, with a different theme each year, and with an average attendance of 250 participants from some 26 countries world-wide. The platform created with the special formula of the symposium, for science and industry, has been well balanced and beneficial to both. Mr. Chairman, ladies and gentlemen, I like to compliment the organizers with the success that they have attained. Allow me to men tion the name of just one person, in whom I like to thank everyone who has been involved in creating the annual Bloedbank-symposia: my warm congratulations to Dr. Smit Sibinga and his staff.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 288 pp. Englisch.

Buch. Condizione: Neu. Neuware - arise automatically as a result of the recursive structure of the task and the continuous nature of the SRN's state space. Elman also introduces a new graphical technique for study ing network behavior based on principal components analysis. He shows that sentences with multiple levels of embedding produce state space trajectories with an intriguing self similar structure. The development and shape of a recurrent network's state space is the subject of Pollack's paper, the most provocative in this collection. Pollack looks more closely at a connectionist network as a continuous dynamical system. He describes a new type of machine learning phenomenon: induction by phase transition. He then shows that under certain conditions, the state space created by these machines can have a fractal or chaotic structure, with a potentially infinite number of states. This is graphically illustrated using a higher-order recurrent network trained to recognize various regular languages over binary strings. Finally, Pollack suggests that it might be possible to exploit the fractal dynamics of these systems to achieve a generative capacity beyond that of finite-state machines.

Neuware - 'The professional schools will resume their professional responsibilities just to the degree that they can discover a science of design, a body of intellectually tough, partly formalizable, partly empirical teachable doctrine about the design process. ' [H.A. Simon, 1968} Design is aimed at the transformation or translation of a specification or high level description into a description in terms of some real-world primitives. As such it involves the removal of the uncertainty about the way in which a required system can be realized. To optimally support the design of systems, we must look at the design process as a whole and at the strong relationship that exists between a designer, the applied design method, the required design tools and the ways in which designs can be expressed. This book focuses on that relationship. The application field we are concerned with is the design of systems in which the communication between system elements is a major design feature. Examples of such communicating systems are: communication protocols, telephone exchange control systems, process control systems, highly modular systems, embedded software, interactive systems, and VLSI systems. In summary, we are concerned with systems in which concurrency plays a major role (concurrency defines the mutual relationship between the activities in the different parts of a system or within a collection of systems).

Buch. Condizione: Neu. Neuware - The development of any Software (Industrial) Intensive System, e.g. critical embedded software, requires both different notations, and a strong devel- ment process. Different notations are mandatory because different aspects of the Software System have to be tackled. A strong development process is mandatory as well because without a strong organization we cannot warrantee the system will meet its requirements. Unfortunately, much more is needed! The different notations that can be used must all possess at least one property: formality. The development process must also have important properties: a exha- tive coverage of the development phases, and a set of well integrated support tools. In Computer Science it is now widely accepted that only formal notations can guarantee a perfect de ned meaning. This becomes a more and more important issue since software systems tend to be distributed in large systems (for instance in safe public transportation systems), and in small ones (for instance numerous processors in luxury cars). Distribution increases the complexity of embedded software while safety criteria get harder to be met. On the other hand, during the past decade Software Engineering techniques have been improved a lot, and are now currently used to conduct systematic and rigorous development of large software systems. UML has become the de facto standard notation for documenting Software Engineering projects. UML is supported by many CASE tools that offer graphical means for the UML notation.

Buch. Condizione: Neu. Neuware -I am very pleased to have been asked to do abrief foreword to this second CRISP volume, The Social Context o[ Coping. I know most of the participants and their work, and respect them as first-rate and influen tial research scholars whose research is at the cusp of current concerns in the field of stress and coping. Psychological stress is central to human adaptation. It is difficult to visualize the study of adaptation, health, illness, personal soundness, and psychopathology without recognizing their dependence on how weil people cope with the stresses of living. Since the editor, John Eckenrode, has portrayed the themes of each of the chapters in his introduction, I can limit myself to a few general comments about stress and coping. Stress research began, as unexplored fields often do, with very sim ple-should I say simplistic -ideas about how to define the concept. Early approaches were unidimensional and input-output in outlook, modeled implicitly on Hooke's late-17th-century engineering analysis in which external load was an environmental stressor, stress was the area over wh ich the load acted, and strain was the deformation of the struc tu re such as a bridge or building.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 310 pp. Englisch.

Buch. Condizione: Neu. Neuware -This book presents an introduction to the study of relationships among per sonality, social skills, and psychopathology. Although research findings dur ing the last decade have made it clear that the relationships among these variables are almost always complex and mUltiply determined, many clini cians and theoreticians have not incorporated such complexities into their models of human behavior and therapeutic intervention. This discrepancy between clinical theory and research-based findings has been of special con cern to us because we have been both empirically oriented academic re searchers and practicing clinicians. It is our belief that clinical theory relat ed to personality, social skills, and psychopathology can be enriched by re search findings from a wide range of fields-from human genetics, tempera ment, and personality to family systems, affect, psychophysiology, and learning. This book is divided into an introductory chapter and three sections. The introductory chapter provides an overview of the issues in the field, compares models, and provides suggestions for further integration and ar ticulation of concepts related to personality, social skills, and psycho pathology. The book's first section presents state-of-the-art general models of interactions among personality, social skills, and psychopathology. Con nolly opens this section with a chapter that reviews longitudinal findings in dicating that personality traits predict the onset of psychopathology and marital distress. The etiology of these and related findings is the subject of other chapters in this section.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 316 pp. Englisch.

Buch. Condizione: Neu. Neuware -PROFESSOR SIR KENNETH L. STUART Pain control has become one ofmedicine's most rapidly growing disciplines, and Iwelcome the opportunity to write this foreword to abook that Iam sure will make its own unique contribution to advancing this discipline. My pleasure in writing it is heightened by my pride in the fact that its editor was at one time an undergraduate student of mine at the University of the West Indies in Jamaica. One of the uncertainties teachers always face is that they can never predict how their charges will turn out. This uncertainty has been happily resolved. Dr. Parris' professional career has been marked by the same dedication and commitment that characterized his undergraduate days and that clearly has been brought to the preparation of this scholarly and practical work. Pain reliefhas been until recently acomparatively neglected field. Its neglect was determined not so much by lack ofprofessional awareness ofits import ance but mainly because so little could be done about it in the past. 336 pp. Englisch.

Buch. Condizione: Neu. Neuware - The importance of drug resistance in cancer chemotherapy cannot be over stated. The 500,000 patients who die every year from cancer in the United States have, in most cases, been treated with chemotherapy. Many of these patients responded initially to chemotherapy, but death resulted from the development of drug-resistant tumors. In the first volume in the series. Drug Resistance in Chemotherapy the results of comprehensive laboratory studies aimed at understanding the mechanisms for resistance to individual agents and to the development of broad cross-resistance were described. In the past 2 years there has been substantial progress in understanding the molecular biology associated with these mechanisms of drug resistance. For the first time we are starting to understand which mechanisms are playing an im portant role in human tumors, and even more importantly, clinical trials have recently been initiated in an effort to reverse specific forms of drug resistance. The purpose of this volume is to describe the new advances, both at the molecular level and in the clinic regarding mechanisms of drug resistance and potential ways this resistance can be circumvented. This volume is focused upon mechanisms of resistance associated with two major classes of anticancer drugs: alkylating agents (including cisplatin) and the natural products (e. g. , adriamycin and vinblastine). The first section of the book describes new insights into the genetic mechanisms associated with drug resistance.

Neuware -Mathematics is playing an ever more important role in the physical and biological sciences, provoking a blurring of boundaries between scientific disciplines and a resurgence of interest in the modern as well as the clas sical techniques of applied mathematics. This renewal of interest, both in research and teaching, has led to the establishment of the series: Texts in Applied Mathematics (TAM). The development of new courses is a natural consequence of a high level of excitement on the research frontier as newer techniques, such as numerical and symbolic computer systems, dynamical systems, and chaos, mix with and reinforce the traditional methods of applied mathematics. Thus, the purpose of this textbook series is to meet the current and future needs of these advances and encourage the teaching of new courses. TAM will publish textbooks suitable for use in advanced undergraduate and beginning graduate courses, and will complement the Applied Mathe matical Sciences ( AMS) series, which will focus on advanced textbooks and research level monographs. Foreword This book is based on a one-semester course for graduate students in the physical sciences and applied mathematics. No great mathematical back ground is needed, but the student should be familiar with the theory of analytic functions of a complex variable. Since the course is on problem solving rather than theorem-proving, the main requirement is that the stu dent should be willing to work out a large number of specific examples.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 292 pp. Englisch.

Neuware -The bright side of the 1980s, or the 'Hispanic decade,' as it was dubbed early on, may ironically turn out to be the detail and sophistication with which the economic and social reversals affecting most Latinos in this period have been tracked, with a fresh cohort of Latino scholars playing an increasingly prominent role in this endeavor. As this volume conveys, these analyses are steadily probing more deeply into the fine grain of the processes bearing on the social conditions of U. S. Latinos and particularly into the diversity of the experiences of the several Latino-origin nationalities until recently generally treated in the aggre gate as 'Hispanics. ' Though still fragmented and tentative in perspective, as are the disciplines on which they draw and the research apparatus on which they rest, the quest among these new voices for a unifying perspective also comes across in this collection of essays. There is manifestly more under way here than a simple demand for inclusion of neglected instances on the margin of supposedly well understood larger or 'mainstream' dynamics. The 1990s open with a more confident assertion of the centrality of the Latino presence and Latino actors in the overarching transformations reshaping U. S. society, and especially in the playing out of these restructurings in the regions and cities of Latino concentra tion.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 332 pp. Englisch.

Buch. Condizione: Neu. This item is printed on demand - Print on Demand Titel. Neuware -Over the past few years, the demand for high speed Digital Signal Proces sing (DSP) has increased dramatically. New applications in real-time image processing, satellite communications, radar signal processing, pattern recogni tion, and real-time signal detection and estimation require major improvements at several levels; algorithmic, architectural, and implementation. These perfor mance requirements can be achieved by employing parallel processing at all levels. Very Large Scale Integration (VLSI) technology supports and provides a good avenue for parallelism. Parallelism offers efficient sohitions to several problems which can arise in VLSI DSP architectures such as: 1. Intermediate data communication and routing: several DSP algorithms, such as FFT, involve excessive data routing and reordering. Parallelism is an efficient mechanism to minimize the silicon cost and speed up the pro cessing time of the intermediate middle stages. 2. Complex DSP applications: the required computation is almost doubled. Parallelism will allow two similar channels processing at the same time. The communication between the two channels has to be minimized. 3. Applicatilm specific systems: this emerging approach should achieve real-time performance in a cost-effective way. 4. Testability and fault tolerance: reliability has become a required feature in most of DSP systems. To achieve such property, the involved time overhead is significant. Parallelism may be the solution to maintain ac ceptable speed performance.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 302 pp. Englisch.

Buch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -This is the first of a two-volume work in the Annals series devoted to developmental psychology. The project was originally conceived in 1985 when Paul van Geert, who had just completed his Theory building in developmental psychology (North Holland, 1986), agreed to col laborate on anAnnals volume examining foundational issues pertaining to the concept of development. The project attracted considerable interest and, in view of the length of the resulting manuscript, a decision was made to publish it in two volumes. Fortunately, the contributors provided coherent perspectives on two relatively distinct developmen tal themes which served to facilitate our task of dividing their contribu tions into two volumes. The first volume deals with the foundations of developmental theory and methodology; the second volume -to appear as Volume 8 of the Annals -with theoretical issues in developmental psychology. In this first volume, the contributions by Willis Overton and Joachim Wohlwill were completed in 1988, those by Roger Dixon, Richard Lerner, and David Hultsch, and Paul van Geert in 1989. Commentaries followed quickly and replies to commentaries were completed in 1990. Paul van Geert provides a general framework within which the founda tional issues of development are discussed. He is especially concerned with the nature of transition models and the structure of time in developmental theory. The relationship between methods and framework, or theory, is the topic of Joachim Wohlwill's contribution. 400 pp. Englisch.

Buch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -Some twenty years have elapsed since the first attempts at planning were made by researchers in artificial intelligence. These early programs concentrated on the development of plans for the solution of puzzles or toy problems, like the rearrangement of stacks of blocks. These early programs provided the foundation for the work described in this book, the automatic generation of plans for industrial assembly. As one reads about the complex and sophisticated planners in the current gen eration, it is important to keep in mind that they are addressing real-world problems. Although these systems may become the 'toy' systems of tomor row, they are providing a solid foundation for future, more general and more advanced planning tools. As demonstrated by the papers in this book, the field of computer-aided mechanical assembly planning is maturing. It now may include: - geometric descriptions of parts extracted from or compatible with CAD programs; - constraints related to part interference and the use of tools; - fixtures and jigs required for the assembly; - the nature of connectors, matings and other relations between parts; - number of turnovers required during the assembly; - handling and gripping requirements for various parts; - automatic identification of subassemblies. This is not an exhaustive list, but it serves to illustrate the complexity of some of the issues which are discussed in this book. Such issues must be considered in the design of the modern planners, as they produce desirable assembly sequences and precedence relations for assembly. 464 pp. Englisch.

Buch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -This book has grown out of our individual experiences as well as our shared ones; out of our differences as well as our commonalities; and out of our conflicts as well as our convergences. Among us there are dif ferences in gender; in individual, family, community, and racial histo ries; in life experiences, identities, and career paths; and even in reasons for writing this book. Of course there are also commonalities. We enjoy one another's company; we enjoy working together; and we feel en riched from our collaboration. We have written this book out of our complete selves, not just our professional selves. The original objective of our book was to present to practitioners of psychotherapy, trainers of psychotherapists, and psychotherapy stu dents a model of conducting psychotherapy that actively acknowledges and builds upon the ethnic and racial heritage of both therapist and client. We have found that to fulfill that objective we need also to acknowledge and build upon the psychological ecology of the therapist and client; and we also need to outline the kind of research necessary if we are to develop and evaluate the perspectives presented here. Those perspectives are embodied in what we have come to call the ethnic validity model (EVM) of psychotherapy. 364 pp. Englisch.

Whereas the industrial revolution heralded the systematic augmentation of human physical limitations by har nessing external energy sources, the infonnation revolution strives to augment human memory and mental processing limitations by harnessing external computational resources. Computers can accumulate. transmit and output much more infonnation and in a more timely fashion than more con ventional printed or spoken media. Of greater interest, however, is the computer's ability to process, classify and retrieve infonnation selectively in response to the needs of each human user. One cannot drink from the fire hydrant of infonnation without being immediately flooded with irrelevant text. Recent technological advances such as optical character readers only exacerbate the problem by increasing the volume of electronic text. Just as steam and internal combustion engines brought powerful energy sources under control to yield useful work in the industrial revolution, so must we build computational engines that control and apply the vast infonnation sources that they may yield useful knowledge. Information science is the study of systematic means to control, classify, process and retrieve vast amounts of infonnation in electronic fonn. In par ticular, several methodologies have been developed to classify texts manually by annies of human indexers, as illustrated quite clearly at the National Library ofMedicine, and many computational techniques have been developed to search textual data bases automatically, such as full-text keyword searches.

Neuware -This volume contains the proceedings of the workshop held in March 1990 at Austin, Texas on Self-Organization, Emerging Properties and Learning. The workshop was co-sponsored by NATO Scientific Affairs Division, Solvay Institutes of Physics and Chemistry, the University of Texas at Austin and IC2 Institute at Austin. It gathered representatives from a large spectrum of scientific endeavour. The subject matter of self-organization extends over several fields such as hydrodynamics, chemistry, biology, neural networks and social sciences. Several key concepts are common to all these different disciplines. In general the self-organization processes in these fields are described in the framework of the nonlinear dynamics, which also governs the mechanisms underlying the learning processes. Because of this common language, it is expected that any progress in one area could benefit other fields, thus a beneficial cross fertilization may result. In last two decades many workshops and conferences had been organized in various specific fields dealing with self-organization and emerging properties of systems. The aim of the workshop in Austin was to bring together researchers from seemingly unrelated areas and interested in self-organization, emerg{ng properties and learning capabilities of interconnected multi-unit systems. The hope was to initiate interesting exchange and lively discussions. The expectations of the organiziers are materialized in this unusual collection of papers, which brings together in a single volume representative research from many related fields. Thus this volume gives to the reader a wider perspective over the generality and ramifications of the key concepts of self organization.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 328 pp. Englisch.

In this first volume, the contributions by Willis Overton and Joachim Wohlwill were completed in 1988, those by Roger Dixon, Richard Lerner, and David Hultsch, and Paul van Geert in 1989. Commentaries followed quickly and replies to commentaries were completed in 1990. Paul van Geert provides a general framework within which the founda tional issues of development are discussed. He is especially concerned with the nature of transition models and the structure of time in developmental theory. The relationship between methods and framework, or theory, is the topic of Joachim Wohlwill's contribution.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 400 pp. Englisch.

Neuware -This book has grown out of our individual experiences as well as our shared ones; out of our differences as well as our commonalities; and out of our conflicts as well as our convergences. Among us there are dif ferences in gender; in individual, family, community, and racial histo ries; in life experiences, identities, and career paths; and even in reasons for writing this book. Of course there are also commonalities. We enjoy one another's company; we enjoy working together; and we feel en riched from our collaboration. We have written this book out of our complete selves, not just our professional selves. The original objective of our book was to present to practitioners of psychotherapy, trainers of psychotherapists, and psychotherapy stu dents a model of conducting psychotherapy that actively acknowledges and builds upon the ethnic and racial heritage of both therapist and client. We have found that to fulfill that objective we need also to acknowledge and build upon the psychological ecology of the therapist and client; and we also need to outline the kind of research necessary if we are to develop and evaluate the perspectives presented here. Those perspectives are embodied in what we have come to call the ethnic validity model (EVM) of psychotherapy.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 356 pp. Englisch.

This item is printed on demand - it takes 3-4 days longer - Neuware -The bright side of the 1980s, or the 'Hispanic decade,' as it was dubbed early on, may ironically turn out to be the detail and sophistication with which the economic and social reversals affecting most Latinos in this period have been tracked, with a fresh cohort of Latino scholars playing an increasingly prominent role in this endeavor. As this volume conveys, these analyses are steadily probing more deeply into the fine grain of the processes bearing on the social conditions of U. S. Latinos and particularly into the diversity of the experiences of the several Latino-origin nationalities until recently generally treated in the aggre gate as 'Hispanics. ' Though still fragmented and tentative in perspective, as are the disciplines on which they draw and the research apparatus on which they rest, the quest among these new voices for a unifying perspective also comes across in this collection of essays. There is manifestly more under way here than a simple demand for inclusion of neglected instances on the margin of supposedly well understood larger or 'mainstream' dynamics. The 1990s open with a more confident assertion of the centrality of the Latino presence and Latino actors in the overarching transformations reshaping U. S. society, and especially in the playing out of these restructurings in the regions and cities of Latino concentra tion. 332 pp. Englisch.

Buch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -Experimental science is a complicated creature. At the head there is a Gordian knot of ideas and hypotheses; behind is the accumulated mass of decades of research. Only the laboratory methods, the legs which propel science forward, remain firmly in touch with the ground. Growth, however is uneven; dinosaurs develop by solid means to give a vast body of results, but few ideas. Others sprint briefly to success with brilliant, though ill-supported, ideas. The problems which this book addresses is to maintain an organic unity between new ideas and the current profusion of innovative experimental tools. Only then can we have the framework on which our research thoughts may flourish. The contributors are outstanding scientists in their respective fields and they record here in a clear manner the methodology with which they perform their experiments. They also illustrate some of their most exciting findings. In all chapters the emphasis is on the critical analysis of the methodology which is often avoided in refereed Journals. These techniques are explained in this book in adequate detail. Each chapter is extensively referenced and contains the most recent material available from author's laboratory at the time of going to press. 508 pp. Englisch.
