This item is printed on demand - it takes 3-4 days longer - Neuware -Self-regulation as a means of mitigating socially undesirable practices in industries such as corruption, environmental degradation, or the violation of human rights is considered a legitimate means of policy. By approaching this phenomenon with the theory of the New Institutional Economics, Jan Sammeck develops an analytical approach that points out the critical mechanisms that decide about the effectiveness of this instrument. By integrating theory with practical examples of self-regulation, this study highlights the necessity to separate that which one deems desirable from that which is feasible, in order to come to a sound judgement about the effectivenes of self-regulation in particular situations. 192 pp. Englisch.

Neuware -Net theory is a theory of systems organization which had its origins, about 20 years ago, in the dissertation of C. A. Petri [1]. Since this seminal paper, nets have been applied in various areas, at the same time being modified and theoretically investigated. In recent time, computer scientists are taking a broader interest in net theory. The main concern of this book is the presentation of those parts of net theory which can serve as a basis for practical application. It introduces the basic net theoretical concepts and ways of thinking, motivates them by means of examples and derives relations between them. Some extended examples il lustrate the method of application of nets. A major emphasis is devoted to those aspect which distinguish nets from other system models. These are for instance, the role of concurrency, an awareness of the finiteness of resources, and the pos sibility of using the same representation technique of different levels of ab straction. On completing this book the reader should have achieved a system atic grounding in the subject allowing him access to the net literature [25]. These objectives determined the subjects treated here. The presentation of the material here is rather more axiomatic than in ductive. We start with the basic notions of 'condition' and 'event' and the con cept of the change of states by (concurrently) occurring events. By generali zation of these notions a part of the theory of nets is presented.Springer-Verlag KG, Sachsenplatz 4-6, 1201 Wien 180 pp. Englisch.

Taschenbuch. Condizione: Neu. This item is printed on demand - Print on Demand Titel. Neuware -As far back as the 1920's, algebra had been accepted as the science studying the properties of sets on which there is defined a particular system of operations. However up until the forties the overwhelming majority of algebraists were investigating merely a few kinds of algebraic structures. These were primarily groups, rings and lattices. The first general theoretical work dealing with arbitrary sets with arbitrary operations is due to G. Birkhoff (1935). During these same years, A. Tarski published an important paper in which he formulated the basic prin ciples of a theory of sets equipped with a system of relations. Such sets are now called models. In contrast to algebra, model theory made abun dant use of the apparatus of mathematical logic. The possibility of making fruitful use of logic not only to study universal algebras but also the more classical parts of algebra such as group theory was dis covered by the author in 1936. During the next twenty-five years, it gradually became clear that the theory of universal algebras and model theory are very intimately related despite a certain difference in the nature of their problems. And it is therefore meaningful to speak of a single theory of algebraic systems dealing with sets on which there is defined a series of operations and relations (algebraic systems). The formal apparatus of the theory is the language of the so-called applied predicate calculus. Thus the theory can be considered to border on logic and algebra.Springer-Verlag KG, Sachsenplatz 4-6, 1201 Wien 336 pp. Englisch.

Neuware -The origins of this volume can be traced back to a conference on 'Ethics, Economic and Business' organized by Columbia Busi ness School in March of 1993, and held in the splendid facilities of Columbia's Casa Italiana. Preliminary versions of several of the papers were presented at that meeting. In July 1994 the Fields Institute of Mathematical Sciences sponsored a workshop on 'Geometry, Topology and Markets': additional papers and more refined versions of the original papers were presented there. They were published in their present versions in Social Choice and Wel fare, volume 14, number 2, 1997. The common aim of these workshops and this volume is to crystallize research in an area which has emerged rapidly in the last fifteen years, the area of topological approaches to social choice and the theory of games. The area is attracting increasing interest from social choice theorists, game theorists, mathematical econ omists and mathematicians, yet there is no authoritative collection of papers in the area. Nor is there any surveyor book to give a perspective and act as a guide to the issues in and contributions to this new area. One of the two aims of this volume is in some measure to play this role: the other aim is of course to present interesting and surprising new results.Springer-Verlag KG, Sachsenplatz 4-6, 1201 Wien 224 pp. Englisch.

Neuware -In recent years there has been a large amount of work on invariant subspaces, motivated by interest in the structure of non-self-adjoint of the results have been obtained in operators on Hilbert space. Some the context of certain general studies: the theory of the characteristic operator function, initiated by Livsic; the study of triangular models by Brodskii and co-workers; and the unitary dilation theory of Sz. Nagy and Foia! Other theorems have proofs and interest independent of any particular structure theory. Since the leading workers in each of the structure theories have written excellent expositions of their work, (cf. Sz.-Nagy-Foia! [1], Brodskii [1], and Gohberg-Krein [1], [2]), in this book we have concentrated on results independent of these theories. We hope that we have given a reasonably complete survey of such results and suggest that readers consult the above references for additional information. The table of contents indicates the material covered. We have restricted ourselves to operators on separable Hilbert space, in spite of the fact that most of the theorems are valid in all Hilbert spaces and many hold in Banach spaces as well. We felt that this restriction was sensible since it eases the exposition and since the separable-Hilbert space case of each of the theorems is generally the most interesting and potentially the most useful case.Springer-Verlag KG, Sachsenplatz 4-6, 1201 Wien 240 pp. Englisch.

Neuware -I - Entire functions of several complex variables constitute an important and original chapter in complex analysis. The study is often motivated by certain applications to specific problems in other areas of mathematics: partial differential equations via the Fourier-Laplace transformation and convolution operators, analytic number theory and problems of transcen dence, or approximation theory, just to name a few. What is important for these applications is to find solutions which satisfy certain growth conditions. The specific problem defines inherently a growth scale, and one seeks a solution of the problem which satisfies certain growth conditions on this scale, and sometimes solutions of minimal asymp totic growth or optimal solutions in some sense. For one complex variable the study of solutions with growth conditions forms the core of the classical theory of entire functions and, historically, the relationship between the number of zeros of an entire function f(z) of one complex variable and the growth of If I (or equivalently log If I) was the first example of a systematic study of growth conditions in a general setting. Problems with growth conditions on the solutions demand much more precise information than existence theorems. The correspondence between two scales of growth can be interpreted often as a correspondence between families of bounded sets in certain Frechet spaces. However, for applications it is of utmost importance to develop precise and explicit representations of the solutions.Springer-Verlag KG, Sachsenplatz 4-6, 1201 Wien 288 pp. Englisch.

Neuware -The objective of the present edition of this monograph is the same as that of earlier editions, namely, to provide readers with some mathemati cal maturity a rigorous and modern introduction to the ideas and principal theorems of probabilistic information theory. It is not necessary that readers have any prior knowledge whatever of information theory. The rapid development of the subject has had the consequence that any one book can now cover only a fraction of the literature. The latter is often written by engineers for engineers, and the mathematical reader may have some difficulty with it. The mathematician who understands the content and methods of this monograph should be able to read the literature and start on research of his own in a subject of mathematical beauty and interest. The present edition differs from the second in the following: Chapter 6 has been completely replaced by one on arbitrarily varying channels. Chapter 7 has been greatly enlarged. Chapter 8 on semi-continuous channels has been drastically shortened, and Chapter 11 on sequential decoding completely removed. The new Chapters 11-15 consist entirely of material which has been developed only in the last few years. The topics discussed are rate distortion, source coding, multiple access channels, and degraded broadcast channels. Even the specialist will find a new approach in the treatment of these subjects. Many of the proofs are new, more perspicuous, and considerably shorter than the original ones.Springer-Verlag KG, Sachsenplatz 4-6, 1201 Wien 192 pp. Englisch.

Neuware -The NATO Advanced Research Workshop on 'Gangliosides and Modu lation of Neuronal Functions' was held at the University of Stutt gart-Hohenheim, Federal Republic of Germany, on October 20 - 24, 1986. About 70 participants from 10 countries presented papers on a wide range of topics all concerning the ganglioside theme. The content of the workshop consisted of the following chap ters: (1) Fundamentals for research on function of gangliosides; (2) Brain ganglioside metabolism; (3) Cell specific distribution and differentiation-related ex pression of brain gangliosides; (4) Gangliosides and neuronal plasticity; (5) Bio-medical potential of exogenous ganglioside application on neuronal function; and (6) Critical assessments on aspects of ganglioside therapy. The aim of the workshop was to sum up and discuss the present knowledge in the respective fields. Despite intensive research on gangliosides ever since Ernst Klenk discovered them in 1936, the biological function of. these amphiphilic, 'sphinx-like' glycosphingo lipids remains elusive. Over the past few years, several thousands of articles on gangliosides have been published demonstrating very special properties of these glycolipids and their possible in volvement in diverse biological phenomena. As far as we know up to the present time, these properties may be due to particular physico-chemical attributes of these compounds, especially in com bination with calcium. The results obtained so far have shed light not only on pos sible functional roles of gangliosides with regard to cellular induction and organization, but have also unexpectedly opened up VI a whole new field of therapeutic applications for these compounds.Springer-Verlag KG, Sachsenplatz 4-6, 1201 Wien 672 pp. Englisch.

Neuware -The increasing use of advanced composite materials in modem structures of high performance calls for a detailed knowledge of their properties. On the other hand, these materials possessing intense anisotropy, and in some cases non homogeneity, require complicated theories based on homogeneous anisotropic elasticity. Typically, such materials either involve fiber-reinforced composites, which are stacked in layers and form laminates, or particulate composites, containing a second phase in powder form. However, each case must be separately analyzed in terms of the particular characteristics of the materials involved and the process of preparation of the com posite systems. Composite materials consisting of more than one destinct phase are in general use in modem industrial applications. Machine parts, structural components and others may be manufactured from such materials. Epoxy resins are suitable matrices for this class of materials. This is due not only to their general-properties such as linear mechanical behavior, transparency, etc., but also to the possibility of modifying their mechanical and optical properties in a very wide range by using suitable modifiers. Their rheological behavior, as well as their dynamic properties have been extensively investigated.Springer-Verlag KG, Sachsenplatz 4-6, 1201 Wien 304 pp. Englisch.

Y ALOW of the basic principles of radioimmunoassay (RIA). During this period of time, RIA methodology has been instrumental to the growth of many areas of biomedical research, including endocrinology, oncology, hematology, and pharmacology. It has done so by providing a relatively simple universal tool allowing, for the first time, the detection of endogenous mediators that are present 12 10 in body fluids at concentrations as low as 10- _10- M. The fundamental nature of this discovery and the wide-ranging fall-out of basic and clinical knowledge derived from its application have been acknowledged by the many honors tributed to its pioneers, including the Nobel Prize awarded to Dr. Y ALOW 10 years ago. Although several excellent books have been published during the past decades covering various aspects of RIA methodology, we felt the need, as pharmacologists, for a comprehensive discussion of the methodological and conceptual issues related to the main classes of mediators of drug action and to drugs themselves. Thus, we gladly accepted the challenge provided by the invitation to edit a volume of the Handbook of Experimental Pharmacology on Radioimmunoassay in Basic and Clinical Pharmacology. We tried to balance the emphasis placed on more general aspects of the RIA methodology and that on specific mediators.Springer-Verlag KG, Sachsenplatz 4-6, 1201 Wien 640 pp. Englisch.

Neuware -During the past decade we have witnessed not only an increase in knowledge of the 'traditional' biophysical problems, but also an understanding of the molecular basis of various biological phenomena. The principles and methods of biophysics now provide an underpin ning of all of the basic biosciences and are the rational language for discussion between scientists of different disciplines. The International School on Biophysics Supramolecular Structure and Function held in Dubrovnik in September 1984 had as its goal to provide comprehensive discussions on a large number of subjects both for younger scientists at the doctoral or postdoctoral level interested in the molecular nature of fundamental biological entities, and for experienced scientists wishing to gain a broader insight into molecular structures and functions. The topics discussed at the School were inter- and intramolecular interactions in biological systems, and the structure, organization, and function of biological macromolecules and supramolecular assemblies. A number of topics were centered around either a biological problem or a physical technique, sometimes giving an unbalanced view of the field under discussion. Some of the topics required previous knowledge of basic biophysical principles, which were then applied to gain greater insight into the molecular functions of diverse supramolecular systems. Although not all the lectures could be prepared for publication in this volume, I hope that it contains valuable up-to-date information on various aspects of the molecular basis of life.Springer-Verlag KG, Sachsenplatz 4-6, 1201 Wien 204 pp. Englisch.

Neuware -The third component of complement, C3, is one of the most versatile proteins and an important participant in immune surveillance and immune response pathways. Its multifunctio nality is based on its ability to interact specifically with multiple serum complement proteins, cell surface receptors, and mem brant;-associated regulatory proteins. One of its most intriguing strategies of interaction with cell surfaces is the covalent binding of activated C3 through the internal thioester. The field has expanded over the past 10 years and a wealth of information has accumulated. C3 from various species and many of the human C3 binding proteins have been cloned and expressed. Numerous cellular responses mediated by the diffe rent fragments of C3 have been described. The findings that C3 interacts in a ligand-receptor-like fashion with proteins of nonself origin such as the gC of herpes simplex virus, a 70-kDa protein from Candida albicans, proteins from Epstein-Barr virus, etc. has opened a new field of investigation. The papers assembled in this volume summarize the wealth of data on the various aspects of the C3 interactions; together they bring to the reader new information on the chemistry, molecular gene tics, biology, and pathophysiology of C3 and C3-binding proteins. Emphasis is given to structural features as they relate to functions. Spring 1989 JOHN D. LAMBRIS, HANS J. MULLER-EBERHARD Table of Contents J. E.
