It also explores the general issues of publishing, including legal considerations, as well the main issues of creating and managing archives. Supported by exercises and discussion questions at the end of each chapter, the book includes some sample assignments suitable for use with students of this subject. A glossary is also provided to help readers understand the specialised vocabulary and the key concepts in the design and assessment of information spaces.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 268 pp. Englisch.

Taschenbuch. Condizione: Neu. Neuware -ETAPS 2002 was the fth instance of the European Joint Conferences on Theory and Practice of Software. ETAPS is an annual federated conference that was established in 1998by combining a number of existing and new conferences. This year it comprised 5 conferences (FOSSACS, FASE, ESOP, CC, TACAS), 13 satellite workshops (ACL2, AGT, CMCS, COCV, DCC, INT, LDTA, SC, SFEDL, SLAP, SPIN, TPTS, and VISS), 8invited lectures (not including those speci c to the satellite events), and several tutorials. The events that comprise ETAPS address various aspects of the system - velopment process, including speci cation, design, implementation, analysis, and improvement. The languages, methodologies, and tools which support these - tivities are all well within its scope. Di erent blends of theory and practice are represented, with an inclination towards theory with a practical motivation on one hand and soundly-based practice on the other. Many of the issues involved in software design apply to systems in general, including hardware systems, and the emphasis on software is not intended to be exclusive. 360 pp. Englisch.

Taschenbuch. Condizione: Neu. Neuware -This volume contains the research reports of the Discovery Science pro ject in Japan (No. 10143106),in which more than 60 scientists participated. It was a three-year pro ject sponsored by Grant-in-Aid for Scienti c Research on Priority Areas from the Ministry of Education,Culture,Sports,Science,and Technology (MEXT) of Japan. This pro ject mainly aimed to (1) develop new methods for knowledge discovery,(2) install network environments for knowledge discovery, and (3) establish Discovery Science as a new area of study in Computer Science / Arti cial Intelligence. In order to attain these aims we set up ve groups for studying the following research areas: (A) Logic for/of Knowledge Discovery (B) Knowledge Discovery by Inference/Reasoning (C) Knowledge Discovery Based on Computational Learning Theory (D) Knowledge Discovery in Huge Databases and Data Mining (E) Knowledge Discovery in Network Environments These research areas and related topics can be regarded as a preliminary d- inition of Discovery Science by enumeration. Thus Discovery Science ranges over philosophy,logic,reasoning,computational learning,and system developments. In addition to these ve research groups we organized a steering group for planning,adjustment,and evaluation of the project. The steering group,chaired by the principal investigator of the project,consists of leaders of the ve research groups and their subgroups as well as advisors from outside of the pro ject. We invited three scientists to consider Discovery Science and the ve above m- tioned research areas from viewpoints of knowledge science,natural language processing,and image processi ng,respectively.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 700 pp. Englisch.

Taschenbuch. Condizione: Neu. Neuware -Data warehouses differ significantly from traditional transaction-oriented operational database applications. Indexing techniques and index structures applied in the transaction-oriented context are not feasible for data warehouses.This work develops specific heuristic indexing techniques which process range queries on aggregated data more efficiently than those traditionally used in transaction-oriented systems. The book presents chapters on: the state of the art in data warehouse research data storage and index structures finding optimal tree-based index structures aggregated data in tree-based index structures performance models for tree-based index structures and techniques for comparing index structures.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 148 pp. Englisch.

Taschenbuch. Condizione: Neu. Neuware -Informatics, the study of the science of information and related disciplines, is being increasingly applied to medicine and healthcare. Medical schools are de veloping departments, divisions, and sections of medical (or biomedical) infor matics, and curricula are being created for medical students and residents. For many practicing physicians, questions such as 'What is informatics ' and 'Why is informatics important in medicine ' are becoming commonplace. Further, once these basics are understood, many physicians seek more complete information about this new 'basic science. ' The goal of this book is to provide primary care physicians with a practical in troductory understanding of medical informatics, focusing on areas of importance in primary care. Additionally, we seek to present clinical contexts in which some of the various applications of medical informatics can be applied. The book begins with an overview of medical informatics, based on the inter action (interface) between the patient and the primary care physician. Next, we study how this interaction can be documented with electronic medical records, and how information on laboratory data and imaging, originating from other elec tronic sources, can be integrated into the electronic medical record. We then cover several areas that concern the content of the information used in primary care. Areas of focus include evidence-based medicine, decision support, knowledge re sources, and patient education. Finally, this book concludes with five chapters concerning practical aspects of primary care informatics: workflow, privacy and security, electronic billing, reporting and analysis, and telecommunications.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 252 pp. Englisch.

Taschenbuch. Condizione: Neu. Neuware -Modern information systems must handle huge amounts of data having varied natural or technological origins. Automated processing of these increasing signal loads requires the training of specialists capable of formalising the problems encountered. This book supplies a formalised, concise presentation of the basis of statistical signal processing. Equal emphasis is placed on approaches related to signal modelling and to signal estimation. In order to supply the reader with the desirable theoretical fundamentals and to allow him to make progress in the discipline, the results presented here are carefully justified. The representation of random signals in the Fourier domain and their filtering are considered. These tools enable linear prediction theory and related classical filtering techniques to be addressed in a simple way. The spectrum identification problem is presented as a first step toward spectrum estimation, which is studied in non-parametric and parametric frameworks. The later chapters introduce synthetically further advanced techniques that will enable the reader to solve signal processing problems of a general nature. Rather than supplying an exhaustive description of existing techniques, this book is designed for students, scientists and research engineers interested in statistical signal processing and who need to acquire the necessary grounding to address the specific problems with which they may be faced. It also supplies a well-organized introduction to the literature.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 352 pp. Englisch.

Taschenbuch. Condizione: Neu. Neuware -Right context, software reuse promises high value to businesses that develop software, opening the door to radical improvements in their software capability (productivity, cost, time to market). Attempts to adopt reuse without a sound understanding of the range of issues involved, however, can lead to expensive failure. This book is for those who are wondering whether they should adopt reuse and how, and also to those who have already started to adopt it but are wondering where they may be going wrong and how they could do better. It consistently emphasizes the practical issues that influence success or failure in reuse; and it offers a concise and balanced coverage of the essentials of the subject, rather than going into undue depth or detail on some topics at the expense of others. It occupies the central ground between being on the one hand an academic textbook and on the other hand a cookbook with ready-made recipes for exactly 'how to do it'. The authors have drawn on their extensive experience of reuse and of software process improvement to provide a readable and balanced coverage of the subject. This book is suitable for business executives, software managers and software developers, regardless of whatever kind of software or applications are developed by their organisations, and whatever the size of those organisations. A special feature of the book is the frequent use of experience notes, drawn from the real-life experience of organisations that have embarked on the reuse adventure.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 248 pp. Englisch.

Buch. Condizione: Neu. Neuware -Compression and Coding Algorithms describes in detail the coding mechanisms that are available for use in data compression systems. The well known Huffman coding technique is one mechanism, but there have been many others developed over the past few decades, and this book describes, explains and assesses them. People undertaking research of software development in the areas of compression and coding algorithms will find this book an indispensable reference. In particular, the careful and detailed description of algorithms and their implementation, plus accompanying pseudo-code that can be readily implemented on computer, make this book a definitive reference in an area currently without one.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 292 pp. Englisch.

Taschenbuch. Condizione: Neu. Neuware -This book provides an accelerated introduction to Maple for scientific programmers who already have experience in other computer languages (such as C, Pascal, or FORTRAN). It gives an overview of the most commonly used constructs and an elementary introduction to Maple programming. The new edition is substantially updated throughout. In particular, there are new programming features especially modules, nested lexical scopes, documentation features, and object-oriented support), a new solution of differential equations, and new plotting features.Review of Earlier Edition'It is especially nice for people like us, who have done some C and FORTRAN programming in our time, but would like to take better advantage of a tool like Maple. It discusses things of key importance to a scientific programmer and does not go on and on with things you'd never use anyway. The examples are terrific--beyond description. I have informed my colleagues here that this is a must-have.'(Brynjulf Owren, Department of Mathematical Sciences, The Norwegian Institute of Technology)Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 304 pp. Englisch.

Taschenbuch. Condizione: Neu. Neuware -This volume is devoted to the Brauer group of a commutative ring and related invariants. Part I presents a new self-contained exposition of the Brauer group of a commutative ring. Included is a systematic development of the theory of Grothendieck topologies and étale cohomology, and discussion of topics such as Gabber's theorem and the theory of Taylor's big Brauer group of algebras without a unit. Part II presents a systematic development of the Galois theory of Hopf algebras with special emphasis on the group of Galois objects of a cocommutative Hopf algebra. The development of the theory is carried out in such a way that the connection to the theory of the Brauer group in Part I is made clear. Recent developments are considered and examples are included.The Brauer-Long group of a Hopf algebra over a commutative ring is discussed in Part III. This provides a link between the first two parts of the volume and is the first time this topic has been discussed in a monograph.Audience: Researchers whose work involves group theory. The first two parts, in particular, can be recommended for supplementary, graduate course use. 508 pp. Englisch.

Taschenbuch. Condizione: Neu. Neuware -The purpose of the book is to present the basic results in the theory of two-person zero-sum repeated games including stochastic games and repeated games with incomplete information. It underlines their relation through the operator approach and covers both asymptotic and uniform properties. The monograph is self-contained including presentation of incomplete information games, minmax theorems and approachability results. It is adressed to graduate students with no previous knowledge of the field.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 224 pp. Englisch.

Buch. Condizione: Neu. Neuware -In the paper we propose a model of tax incentives optimization for inve- ment projects with a help of the mechanism of accelerated depreciation. Unlike the tax holidays which influence on effective income tax rate, accelerated - preciation affects on taxable income. In modern economic practice the state actively use for an attraction of - vestment into the creation of new enterprises such mechanisms as accelerated depreciation and tax holidays. The problem under our consideration is the following. Assume that the state (region) is interested in realization of a certain investment project, for ex- ple, the creation of a new enterprise. In order to attract a potential investor the state decides to use a mechanism of accelerated tax depreciation. The foll- ing question arise. What is a reasonable principle for choosing depreciation rate From the state¿s point of view the future investor¿s behavior will be rat- nal. It means that while looking at economic environment the investor choose such a moment for investment which maximizes his expected net present value (NPV) from the given project. For this case both criteria and ¿investment rule¿ depend on proposed (by the state) depreciation policy. For the simplicity we will suppose that the purpose of the state for a given project is a maximi- tion of a discounted tax payments into the budget from the enterprise after its creation. Of course, these payments depend on the moment of investor¿s entry and, therefore, on the depreciation policy established by the state.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 260 pp. Englisch.

Buch. Condizione: Neu. Neuware -This volume began as the last part of a one-term graduate course given at the Fields Institute for Research in the Mathematical Sciences in the Autumn of 1993. The course was one of four associated with the 1993-94 Fields Institute programme, which I helped to organise, entitled 'Artin L-functions'. Published as [132]' the final chapter of the course introduced a manner in which to construct class-group valued invariants from Galois actions on the algebraic K-groups, in dimensions two and three, of number rings. These invariants were inspired by the analogous Chin burg invariants of [34], which correspond to dimensions zero and one. The classical Chinburg invariants measure the Galois structure of classical objects such as units in rings of algebraic integers. However, at the 'Galois Module Structure' workshop in February 1994, discussions about my invariant (0,1 (L/ K, 3) in the notation of Chapter 5) after my lecture revealed that a number of other higher-dimensional co homological and motivic invariants of a similar nature were beginning to surface in the work of several authors. Encouraged by this trend and convinced that K-theory is the archetypical motivic cohomology theory, I gratefully took the opportunity of collaboration on computing and generalizing these K-theoretic invariants. These generalizations took several forms - local and global, for example - as I followed part of number theory and the prevalent trends in the 'Galois Module Structure' arithmetic geometry.Springer Basel AG in Springer Science + Business Media, Heidelberger Platz 3, 14197 Berlin 324 pp. Englisch.

Buch. Condizione: Neu. Neuware -Scholars of different schools have extensively analyzed world systems as networks of communication under the fashionable heading `globalization.' Our collected new research pushes the argument one step further. Globalization is not a homogenization of all social life on earth. It is a heterogeneous process that connects the global and the local on different levels. To understand these contemporary developments this book employs innovative concepts, strategies of research, and explanations. Globalization is a metaphor for different borderstructures, new borderlines, and conditions of membership, which emerge in a global world-system. As a world-system expands it incorporates new territories and new peoples. The process of incorporation creates frontiers or boundaries of the world-system. These frontiers or boundary zones are the locus of resistance to incorporation, ethnogenesis, ethnic transformation, and ethnocide.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 264 pp. Englisch.

Buch. Condizione: Neu. Neuware -Social Networks and Trust discusses two possible explanations for the emergence of trust via social networks. If network members can sanction untrustworthiness of actors, these actors may refrain from acting in an untrustworthy manner. Moreover, if actors are informed regularly about trustworthy behavior of others, trust will grow among these actors.A unique combination of formal model building and empirical methodology is used to derive and test hypotheses about the effects of networks on trust. The models combine elements from game theory, which is mainly used in economics, and social network analysis, which is mainly used in sociology.The hypotheses are tested (1) by analyzing contracts in information technology transactions from a survey on small and medium-sized enterprises and (2) by studying judgments of subjects in a vignette experiment related to hypothetical transactions with a used-car dealer.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 292 pp. Englisch.

Buch. Condizione: Neu. Neuware -Research in real estate finance and economics has developed in an exciting way in the past twenty-five years or so. The resulting theoretical and empirical findings are shining a new light on some of the classic mysteries of the real estate markets. It is good to see that a growing proportion of this research output is concerned with contemporary problems and issues regarding the European and Far Eastern property markets.To stimulate a creative exchange of new ideas and a debate of the latest research findings regarding the global property markets, the Maastricht-Cambridge Real Estate Finance and Investment Symposium was established. This initiative aims at bringing together a number of leading researchers in the field for a short, intensive conference. The 2000 Symposium, which was hosted by Maastricht University in the Netherlands in June of that year, is the first in an annual series of such conferences, which will alternate between Maastricht University and Cambridge University. This book is a compilation of the papers originally presented at the first Maastricht-Cambridge Symposium in 2000.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 204 pp. Englisch.

Buch. Condizione: Neu. Neuware -Nicolas Buclet Waste management issues can be approached in several ways. The question of which treatment technique to adopt is essentially a downstream problem. In our view the issue needed to be tackled further upstream. Waste management is not only a technical problem, it is also an area which involves various actors throughout society. In this book, as in the previous volume (Buclet, Godard, 2000), the organisation of waste management is seen in terms of regimes. A regime is an entire form ofinstitutional, technical, economic and social organisation relating to a specific field, no matter how complex that field is. Regime formation is generally a long-drawn-out process, rooted in the multiple interactions of the actors involved. Legislation plays a crucial role but would not, of itself, lead to the formation of a regime. There is always the old question of causality and which element occurs first: the behaviour of actors who constitute the reality, or the legislation that models their behaviour Besides legislation, other formal or informal conventions influence the behaviour of actors approaching a common path, making co ordination easier between them. In this book we have insisted on conventional principles. They are the real guides for actors within each national regime.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 220 pp. Englisch.

Buch. Condizione: Neu. Neuware -Economic Theory, academic policy analysis and public policy design are becoming more interdependent. Hence, the demands for close interactions between the policy community and the research community have been rising significantly. This book assesses how recent economic thinking has advanced under these influences. Furthermore, it evaluates the important contribution economics can add to the design and evaluation of public policy, now more than ever before. The study is of interest to policy makers, policy analysts, researchers and students of economics at all levels. The authors, which include many of Germany's most eminent economists, draw on their wide experience in research and consultancy to present a coherent view of where European economic theory stands today and how it can play a role in the management of the economy of the new millennium.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 498 pp. Englisch.

Buch. Condizione: Neu. Neuware -The generous social welfare system in Europe is one of the most important differences between Europe and the US. Defenders of the European welfare state argue that it improves social cohesion and prevents crime. Others argue that the 'invisible hand' in the US economy is equally powerful in reducing unemployment and preventing crime. This book takes this trade-off as a starting point and contributes to a better interdisciplinary understanding of the interactions between crime, economic performance and social exclusion. In doing so, it evaluates the existing economic and criminological research and provides innovative empirical investigations on the basis of international panel data sets from different levels of regional aggregation.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 252 pp. Englisch.

A chapter on the molecular basis ofanxiety is included, outlining the potential of such approach in thediscovery of novel effective pharmacological interventions. The facevalidity, predictability and usefulness of animal models in the designof valid new efficacious products are discussed. Separate chaptersdedicated to each particular type of anxiety such as generalized anxietydisorder, social phobia, posttraumatic stress disorder, panic andobsessive-compulive disorder are included.This book should be of benefit to psychiatrists, clinical psychologistsgeneral practitioners, nurses, students and all those engaged inneuropsychiatric research.Springer Basel AG in Springer Science + Business Media, Heidelberger Platz 3, 14197 Berlin 324 pp. Englisch.

Buch. Condizione: Neu. Neuware -From September 13 to 17 in 1999, the First China-Japan Seminar on Number Theory was held in Beijing, China, which was organized by the Institute of Mathematics, Academia Sinica jointly with Department of Mathematics, Peking University. TE:m Japanese Professors and eighteen Chinese Professors attended this seminar. Professor Yuan Wang was the chairman, and Professor Chengbiao Pan was the vice-chairman. This seminar was planned and prepared by Professor Shigeru Kanemitsu and the first-named editor. Talks covered various research fields including analytic number theory, algebraic number theory, modular forms and transcendental number theory. The Great Wall and acrobatics impressed Japanese visitors. From November 29 to December 3 in 1999, an annual conference on analytic number theory was held in Kyoto, Japan, as one of the conferences supported by Research Institute of Mathematical Sciences (RIMS), Kyoto University. The organizer was the second-named editor. About one hundred Japanese scholars and some foreign visitors com ing from China, France, Germany and India attended this conference. Talks covered many branches in number theory. The scenery in Kyoto, Arashiyama Mountain and Katsura River impressed foreign visitors. An informal report of this conference was published as the volume 1160 of Surikaiseki Kenkyusho Kokyuroku (June 2000), published by RIMS, Ky oto University. The present book is the Proceedings of these two conferences, which records mainly some recent progress in number theory in China and Japan and reflects the academic exchanging between China and Japan.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 428 pp. Englisch.

Buch. Condizione: Neu. Neuware -Selenium is a naturally occurring trace element that can become concentrated and released by industrial, agricultural, petrochemical and mining activities. At concentrated levels it is toxic and has polluted ecosystems around the world. This book will serve as a comprehensive practical handbook for everyone dealing with selenium in aquatic environments. It offers field-tested approaches and methods for assessment and water quality management. Using his twenty-year experience, the author discusses the effects of selenium on fish and bird populations and presents guidelines for identifying sources of pollution, interpreting selenium concentrations, assessing hazardous conditions, setting water quality criteria and ecosystem loading limits (TMDLs). He also includes a procedure for setting environmentally safe limits that ensure compliance with EPA regulations.Selenium Assessment in Aquatic Ecosystems will interest field scientists, natural resource managers, risk assessors and environmental planners.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 180 pp. Englisch.

Buch. Condizione: Neu. Neuware -For many, modern functional analysis dates back to Banach's book [Ba32]. Here, such powerful results as the Hahn-Banach theorem, the open-mapping theorem and the uniform boundedness principle were developed in the setting of complete normed and complete metrizable spaces. When analysts realized the power and applicability of these methods, they sought to generalize the concept of a metric space and to broaden the scope of these theorems. Topological methods had been generally available since the appearance of Hausdorff's book in 1914. So it is surprising that it took so long to recognize that they could provide the means for this generalization. Indeed, the theory of topo logical vector spaces was developed systematically only after 1950 by a great many different people, induding Bourbaki, Dieudonne, Grothendieck, Köthe, Mackey, Schwartz and Treves. The resulting body of work produced a whole new area of mathematics and generalized Banach's results. One of the great successes here was the development of the theory of distributions. While the not ion of a convergent sequence is very old, that of a convergent fil ter dates back only to Cartan [Ca]. And while sequential convergence structures date back to Frechet [Fr], filter convergence structures are much more recent: [Ch], [Ko] and [Fi]. Initially, convergence spaces and convergence vector spaces were used by [Ko], [Wl], [Ba], [Ke64], [Ke65], [Ke74], [FB] and in particular [Bz] for topology and analysis.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 284 pp. Englisch.

Buch. Condizione: Neu. Neuware -The history of martingale theory goes back to the early fifties when Doob [57] pointed out the connection between martingales and analytic functions. On the basis of Burkholder's scientific achievements the mar tingale theory can perfectly well be applied in complex analysis and in the theory of classical Hardy spaces. This connection is the main point of Durrett's book [60]. The martingale theory can also be well applied in stochastics and mathematical finance. The theories of the one-parameter martingale and the classical Hardy spaces are discussed exhaustively in the literature (see Garsia [83], Neveu [138], Dellacherie and Meyer [54, 55], Long [124], Weisz [216] and Duren [59], Stein [193, 194], Stein and Weiss [192], Lu [125], Uchiyama [205]). The theory of more-parameter martingales and martingale Hardy spaces is investigated in Imkeller [107] and Weisz [216]. This is the first mono graph which considers the theory of more-parameter classical Hardy spaces. The methods of proofs for one and several parameters are en tirely different; in most cases the theorems stated for several parameters are much more difficult to verify. The so-called atomic decomposition method that can be applied both in the one-and more-parameter cases, was considered for martingales by the author in [216].Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 356 pp. Englisch.

Buch. Condizione: Neu. Neuware -Recent droughts in Africa and elsewhere in the world, from China to Peru, have serious implications for food security and grave consequences for local and international politics. The issues do not just concern the plight of African peoples, but also our global ecological future.Global climatic changes become manifest initially in regions that are marginal or unstable. Africa's Sahel zone is one of the most sensitive climatic regions in the world and the events that have gripped that region beginning in the 1970's were the first indicator of a significant shift in global climatic conditions.This work aims to bring archaeology with the domain on contemporary human affairs and to forge a new methodology for coping with environmental problems from an archaeological perspective. Using the later prehistory of Africa as a comparison, the utility of this methodological strategy in interpreting culture change and assessing long-term response to current, global climatic fluctuations is examined and understood.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 368 pp. Englisch.
