Buch. Etat : Neu. Neuware -This book is a synopsis of modern deep-field astronomy, based on the powerful telescopes and instruments developed in recent years. It is organized along topical themes, such as the extragalactic background radiation at different wavelengths, the evolution of galaxies, the history of star formation, the nature of absorbers, the reionization of the intergalactic medium, the validity of photometric redshifts, gravitational lensing, and clustering of galaxies. Stellar and substellar objects were not neglected, however, and one session was devoted to nearby bodies such as trans-Neptunian solar system objects, brown dwarfs, and stars with special characteristics.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 408 pp. Englisch.

Taschenbuch. Etat : Neu. Neuware -The engineering life cycle for complex systems design and development, where partners are dispersed in different locations, requires the set-up of adequate and controlled processes involving many different disciplines. The ¿design integration¿ and the final ¿system physical/functional integration and qualification¿ imply a high degree of cross-interaction among the partners. The - place technical information systems supporting the life cycle activities are specialized with respect to the needs of each actor in the process chain and are highly heterogeneous between them. To globally innovate in-place processes, specialists must be able to work as a unique team, in a virtual enterprise model. To this aim, it is necessary to make interoperable the different technical information systems and to define co-operative engineering processes, which take into account ¿distributed roles¿, ¿shared activities¿, and ¿distributed process controls¿. In this frame an innovative study, aimed at addressing this process with the goal of identifying proper solutions ¿ in terms of design, implementation, and deployment ¿ has been carried out with the support of the European Community and the participation of major industrial companies and research centers.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 296 pp. Englisch.

Taschenbuch. Etat : Neu. Neuware -The term ¿agent¿ is one of those catchwords that mean widely differing things to different people. To telecommunications people it is little more than a mobile piece of code that may be executed at any place. At the other extreme, AI people often associate with agents human-like traits such as social behavior. In between, software people view agents as fairly self-contained pieces of software that, at the low end, pretty much act like objects and, at the high end, more or less auto- mously decide when and how to react to stimuli or proactively initiate effects that can be observed from their environment. Software agents are particularly important when it comes to distributed en- ronments. There, much of the communication takes place asynchronously, that is the sequence of events cannot be planned ahead in all detail. Instead, agents are given rules as to how to interpret the current situation and, given a common goal, so that they adjust their response accordingly.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 228 pp. Englisch.

Taschenbuch. Etat : Neu. Neuware -The notion of amenability has its origins in the beginnings of modern measure theory: Does a finitely additive set function exist which is invariant under a certain group action Since the 1940s, amenability has become an important concept in abstract harmonic analysis (or rather, more generally, in the theory of semitopological semigroups). In 1972, B.E. Johnson showed that the amenability of a locally compact group G can be characterized in terms of the Hochschild cohomology of its group algebra L^1(G): this initiated the theory of amenable Banach algebras. Since then, amenability has penetrated other branches of mathematics, such as von Neumann algebras, operator spaces, and even differential geometry. Lectures on Amenability introduces second year graduate students to this fascinating area of modern mathematics and leads them to a level from where they can go on to read original papers on the subject. Numerous exercises are interspersed in the text.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 316 pp. Englisch.

Taschenbuch. Etat : Neu. Neuware -Themultiset (a set with multiplicities associated with its elements, in the form of natural numbers) is a notion which has appeared again and again in many areas of mathematics and computer science, sometimes called abag (some h- torical information appears in the enclosed paper by A. Syropoulos). As a data structure, this notion stands ¿in-between¿strings/lists, where a linear ordering of symbols/items is present, andsets, where no ordering and no multiplicity is considered;inamultiset,onlythemultiplicityofelementsmatters,no ttheir ordering. Actually, in between lists and multisets we also havepomsets, partially ordered multisets. Con ning ourselves to computer science, we may mention many areas where multisets are used: formal power series, Petri nets, data bases, logics, formal language theory (in relation with Parikh mapping, commutative grammars, etc), concurrency, and so on. In the last few years, the notion has occurred in a rather natural way in the molecular computing area. An aqueous solution of chemical compounds, swimming together in a given space, without any given spatial relation between individual elements, is just a multiset. Actually, this chemical metaphor was used several years before the occurrence of what is now called molecular computing, as the basic ingredient of the Gamma language and the Chemical Abstract Machine (a comprehensive survey of these ideas is provided by J. -P. Ban¿ atre, P. Fradet, D. Le Metayer).Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 372 pp. Englisch.

Buch. Etat : Neu. Neuware -The information received from BeppoSAX, Chandra and other instruments in the last two years has more than doubled the number of samples of Gamma-Ray Bursts localized and followed up for afterglow search. This has also increased the interest of astronomers in GRBs. This book reviews the research of the last two years and covers the global properties of GRBs, GRB afterglows, GRB host galaxies, cosmology using GRBs, and theories for GRBs and their afterglows. Theoretical and observational aspects are presented as well as tools for the analysis of the data.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 484 pp. Englisch.

Buch. Etat : Neu. Neuware -The book series on the ethics of science and technology assessment edited by the Europ ische Akademie is devoted to the publication of the work-reports of its project groups, works on the foundations of ethics, the philosophy science, and other issues related to the work of the Europ ische Akademie. In addition, the series comprises the proceedings of conferences organized by the academy. The 13th volume documents the proceeding of the academy's spring symposium in 2000 on Rationing in Medicine which was held in Bad Neuenahr-Ahrweiler on March 23-25, 2000. An intense discussion on the future of health care in Europe has been stimulated by increasing difficulties of securing adequate and needs orientated medical care in the face of scarce resources and medical progress. Un fortunately, quite of ten a rational discussion of rationing is drowned out by the politic al talk of the day. But only an open and well-informed debate, if anything at ali, can lead to transparent and just rationing procedures which eventually might be acceptable to the public at large. For this debate much can be learnt from observing the experiences other countries have made with their health care arrangements. What kinds of mistakes should be avoided and what might be useful in the different states and perhaps also in the supra-national context of an emerging Europe are interesting and important issues.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 152 pp. Englisch.

Taschenbuch. Etat : Neu. Neuware -Since their introduction nearly 40 years ago, research on Petri nets has diverged in many different directions. Various classes of Petri net, motivated either by theory or applications, with its own specific features and methods of analysis, have been proposed and studies in depth.These successful developments have led to a very heterogeneous landscape of diverse models, and this, in turn, has stimulated research on concepts and approaches that contribute to unifying and structuring the diverse landscape. This state-of-the-art survey presents the most relevant approaches to unifying Petri nets in a systematic and coherent way. The 14 chapters written by leading researchers are organized in topical sections on application-oriented approaches, unifying frameworks, and theoretical approaches.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 500 pp. Englisch.

Buch. Etat : Neu. Neuware -The Complexity Theory Companion is an accessible, algorithmically oriented, research-centered, up-to-date guide to some of the most interesting techniques of complexity theory.The book's thesis is that simple algorithms are at the heart of complexity theory. From the tree-pruning and interval-pruning algorithms that shape the first chapter to the query simulation procedures that dominate the last chapter, the central proof methods of the book are algorithmic. And to more clearly highlight the role of algorithmic techniques in complexity theory, the book is - unlike other texts on complexity - organized by technique rather than by topic. Each chapter of this book focuses on one technique: what it is, and what results and applications it yields.This textbook was developed at the University of Rochester in courses given to graduate students and advanced undergraduates. Researchers also will find this book a valuable source of reference due to the comprehensive bibliography of close to five hundred entries, the thirty-five page subject index, and the appendices giving overviews of complexity classes and reductions.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 388 pp. Englisch.

Buch. Etat : Neu. Neuware -After the positive experience made in 1999, with the research and consequent publication of the volume 'Banking Privatisation in Europe. The Process and the Consequences on Strategies and Organisational Structures', published by Springer-Verlag, we have decided to set up a new group of researchers to study the present changes within the European postal systems and the privatisation developments. Starting from our competencies and specific knowledge - financial markets and management of bank intermediaries - our research has basically focussed onto the posts' financial services offer and their future perspectives. The subject is particularly interesting considering the radical changes, which are giving to 'the postal activity and the competition itself a new profile. And this reality paves the way to new opportunities in the market segment of financial services for retail customers and, at the same time, it brings in new threats. Our approach is the approach of compared analysis in Europe in order to detect common trends in the development or possible specific features, as well as positioning perspectives of the different national Posts in the single market of financial services. Our working group has benefited from the collaboration of researchers and experts with different nationality, university education and experience. Eminent representatives of postal companies, regulation and control bodies, banks and financial institutes have been interviewed and have allowed precious elements to deepen our knowledge and capacity of interpreting the present trends.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 284 pp. Englisch.

Buch. Etat : Neu. Neuware -The Bachelier Society for Mathematical Finance held its first World Congress in Paris last year, and coincided with the centenary of Louis Bacheliers thesis defence. In his thesis Bachelier introduces Brownian motion as a tool for the analysis of financial markets as well as the exact definition of options. The thesis is viewed by many the key event that marked the emergence of mathematical finance as a scientific discipline. The prestigious list of plenary speakers in Paris included two Nobel laureates, Paul Samuelson and Robert Merton, and the mathematicians Henry McKean and S.R.S. Varadhan. Over 130 further selected talks were given in three parallel sessions. .Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 536 pp. Englisch.

Buch. Etat : Neu. Neuware -Tanzania is one of the most biologically diverse nations in the world. Traveling from west to east across Tanzania, one encounters an incredible array of ecosystems and species. Beginning at Lakes Victoria, Tanganyika, and Nyasa that form much of the western boundary of Tanzania, one finds the most diverse and some of the most spectacular concentrations of endemic fish in any of the world's lakes. Moving further inland from the lakes, one meets the woodlands and plains of Serengeti, Ngorongoro, Tarangire, and Lake Manyara. The assemblages and movements of large mammals in these protected areas are unparalleled worldwide. Traveling yet further to the east, one comes to Mount Kilimanjaro, the highest mountain in Africa. Mount Kilimanjaro is of sufficient height to not only contain seven major vegetation zones, but also maintain permanent glaciers. Finally, shortly before arriving at the Indian Ocean, one encounters the Eastern Arc Mountains, a series of isolated and geologically ancient mountains, which due to their height and proximity to the Indian Ocean intercept sufficient precipitation to support, in many areas, moist tropical forest. The Eastern Arc Mountains are among the richest sites biologically in all of Africa and harbor unusually high concentrations of endemic species - species whose geographic distribution are restricted to these mountains. Unfortunately, much of Tanzania's biodiversity is threatened by habitat alteration, destruction, and exploitation. The Eastern Arc forests face some of the most severe threats to any of Tanzania's biologically unique sites.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 212 pp. Englisch.

Buch. Etat : Neu. Neuware -Geomorphology deals with some of the most striking patterns of nature. From mountain ranges and mid-ocean ridges to river networks and sand dunes, there is a whole family of forms, structures, and shapes that demand rationalization as well as mathematical description. In the various chapters of this volume, many of these patterns are explored and discussed, and attempts are made to both unravel the reasons for their very existence and to describe their dynamics in quantitative terms. Particular focus is placed on lava and mud flows, ice and snow dynamics, river and coastal morphodynamics and landscape formation. Combining a pedagogical approach with up-to-date reviews of forefront research, this volume will serve both postgraduate students and lecturers in search of advanced textbook material, and experienced researchers wishing to get acquainted with the various physical and mathematical approaches in a range of closely related research fields.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 596 pp. Englisch.

Buch. Etat : Neu. Neuware -Both the high level of activity in worldwide space exploration programmes and the discovery of extra-solar planets have spurred renewed interest in the physics and evolution dynamics of solar systems. The present book has grown out of a set of lectures by leading experts in the field within the framework of the well-known EADN summer schools. It addresses primarily graduate students and young researchers but will be equally useful for scientists in search of a comprehensive tutorial account that goes beyond the material found in standard textbooks. 280 pp. Englisch.

Buch. Etat : Neu. Neuware -Do our genes determine our behavior Do education and environment have any influence at all Do humans occupy a unique position in evolution To clarify these provoking questions, the author takes the reader on an ambitious and entertaining journey through a variety of scientific disciplines. In doing so, he creates an image of human evolution that says that our entire individual knowledge is determined - to the smallest detail - by phylogeny. ' . before shocked humanists discard such radical theses as mere nonsense, they should not completely close their minds to the explanations of a biologist who says that we still know very little about the genetic determination of human behavior and that the invariance of many forms of behavior present in all cultures nourish the suspicion that the determining role of genes is probably far more comprehensive than we have ever dreamed.'Wolfgang Wieser, translated from his review in 'Merkur' (Sept./Oct. 1999)Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 364 pp. Englisch.

Buch. Etat : Neu. Neuware -The bacterial cell wall represents a very complex structure disconnecting the interior of single-cell organisms from the environment, thus protecting, but also enabling, them to interact with the surrounding milieu and to exchange both substances and information. Knowledge of the biochemistry of the cell wall (components) and the genetic background helps to understand their significance with regard to microbiology and immunology of bacteria. This book represents the second edition of a publication which was presented nearly 20 years ago in the German language (Die bakterielle Zellwand). Since that time our knowledge in this field has been significantly enlarged. Therefore, the manuscript had to be completely revised and updated. To maintain both the size and the introductory character of the book at least to a great extent, the authors had to restrict the presented material to that which appears basic and most important. This requirement must inevitably bring about many subjective factors. As pointed out in the first edition, the term cell wall was not taken too strictly. Since the constituents located outside the cytoplasmic membrane are frequently difficult to divide in structure, localisation, and/or function into true cell wall components and supplementary substances, they are all at least briefly mentioned.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 292 pp. Englisch.

Buch. Etat : Neu. Neuware -A renewed interest in aliphatic polyesters has resulted in developing materials important in the biomedical and ecological fields. Mainly materials such as PLA and PCL homopolymers have so far been used in most applications. There are many other monomers which can be used. Different molecular structures give a wider range of physical properties as well as the possibility of regulating the degradation rate. By using different types of initiators and catalysts, ring-opening polymerization of lactones and lactides provides macromolecules with advanced molecular architectures. In the future, new degradable polymers should be able to participate in the metabolism of nature. Some examples of novel polymers with inherent environmentally favorable properties such as renewability and degradability and a series of interesting monomers found in the metabolisms and cycles of nature are given.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 196 pp. Englisch.

Buch. Etat : Neu. Neuware -Deutschland befindet sich in einem harten internationalen Wettbewerb um qualifizierte Arbeitskräfte. Dabei steht der aktuelle Fachkräftemangel nur scheinbar im Gegensatz zu einer anhaltend hohen Arbeitslosigkeit von Geringqualifizierten. Gewichtige demographische Argumente sprechen für eine gezielte Auswahl von Zuwanderern anhand arbeitsmarktbezogener Kriterien. Dieser Konstellation kann die Politik ohne eine ökonomischen Regeln gehorchende Steuerung der Zuwanderung nicht gerecht werden. Das Buch analysiert die kurz- und langfristige Engpaßsituation auf dem deutschen Arbeitsmarkt und entwickelt ein umfassendes Konzept zur Neugestaltung der Zuwanderung nach Deutschland.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 312 pp. Deutsch.
