Buch. Condición: Neu. Neuware -Personal computers have made life convenient in many ways, but what about their impacts on the environment due to production, use and disposal Manufacturing computers requires prodigious quantities of fossil fuels, toxic chemicals and water. Rapid improvements in performance mean we often buy a new machine every 1-3 years, which adds up to mountains of waste computers. How should societies respond to manage these environmental impacts This volume addresses the environmental impacts and management of computers through a set of analyses on issues ranging from environmental assessment, technologies for recycling, consumer behaviour, strategies of computer manufacturing firms, and government policies. One conclusion is that extending the lifespan of computers (e.g. through reselling) is an environmentally and economically effective strategy that deserves more attention from governments, firms and the general public.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 296 pp. Englisch.

Buch. Condición: Neu. Neuware -African Americans constitute one of the most interesting and dynamic components of the population of the United States. Unfortunately, an accurate assessment of their demographic characteristics is beset by inaccuracies in the underlying data. Using a novel strategy that combines record linkage and demographic/statistical analysis, the authors produce an internally consistent and robust set of estimates of the African-American population during the period 1930-1990. They interpret the record that emerges, with special reference to longevity trends and differentials. This work is of particular interest to demographers, sociologists and students of ethnic studies.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 224 pp. Englisch.

Buch. Condición: Neu. Neuware -Olof Dahlbäck's book breaks new ground for the analysis of crime from a rationality perspective by presenting models and methods that go far beyond those with which researchers have hitherto been equipped. The book examines single crimes, individual criminality, and societal crime, and it discusses thoroughly the general decision theoretical presuppositions necessary for analyzing these various types of crime. An expected utility maximization model for a single discrete choice regarding the commission of a crime is the foundation of most of the analyses presented. A version of this model is developed that permits interpersonal comparisons, and this basic model is used when deriving more complex models of crime as well as when analyzing the potential for such derivations. The rigorous, powerful methods suggested provide considerable opportunities for improving research and for seeing old problems in a new light.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 232 pp. Englisch.

Buch. Condición: Neu. Neuware -Introd uction The problem of integrability or nonintegrability of dynamical systems is one of the central problems of mathematics and mechanics. Integrable cases are of considerable interest, since, by examining them, one can study general laws of behavior for the solutions of these systems. The classical approach to studying dynamical systems assumes a search for explicit formulas for the solutions of motion equations and then their analysis. This approach stimulated the development of new areas in mathematics, such as the al gebraic integration and the theory of elliptic and theta functions. In spite of this, the qualitative methods of studying dynamical systems are much actual. It was Poincare who founded the qualitative theory of differential equa tions. Poincare, working out qualitative methods, studied the problems of celestial mechanics and cosmology in which it is especially important to understand the behavior of trajectories of motion, i.e., the solutions of differential equations at infinite time. Namely, beginning from Poincare systems of equations (in connection with the study of the problems of ce lestial mechanics), the right-hand parts of which don't depend explicitly on the independent variable of time, i.e., dynamical systems, are studied.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 200 pp. Englisch.

Buch. Condición: Neu. Neuware -Mycotoxins continue to be a very serious threat to human health and a major concern for those entrusted with regulatingthesafetyoffoodandfoodproducts.Infectionofcerealsand othercrops,notablegrapevine,byFusarium, Aspergillus andPenicillium are a world-wide problem and recent epidemics in Europe, the USA and Canada have focused attention on this problem. A previous Special Issue of the European Journal of Plant Pathology (108 (7) 2003) was concerned with the nature of these toxins and the fungi that can produce them. The aim of this publication is to review the environmental factors that in uence the success of these fungi as pathogens and as organisms affecting stored products, and to discuss how these factors can also in uence the amounts of toxin that accumulate. These reviews were originally presented at a Workshop of the EU COST Action 835 entitled ¿Agriculturally Important Toxigenic Fungi¿ (Chairperson Antonio Logrieco, Bari, Italy), held in East Malling, UK at the Horticultural Research International in September 2002. We hope the information provided will stimulate scientists world-wide to assess the risk of toxins accumulating in plants under a range of environmental conditions and that this will provide an insight into how the accumulation of these toxins can be kept to a minimum.

Taschenbuch. Condición: Neu. Neuware -This book is based partly on a. lecture course given at the University of Tri este, but mostly on my own research experience in the field of galactic chemical evolution. The subject of galactic chemical evolution was started and developed by Beat rice Tinsley in the seventies and now is a flourishing subject. This book is dedi cated to the chemical evolution of our Galaxy and aims at giving an up-to-date review of what we have learned since Tinsley's pioneering efforts. At the time of writing, in fact, books of this kind were not available with the exception of the excellent book by Bernard Pagel on 'Nucleosynthesis and Chemical Evolution of Galaxies' (Cambridge University Press, 1997), and the subject of galactic chem ical evolution has appeared only as short chapters in books devoted to other subjects. Therefore, I felt that a book of this kind could be useful. The book summarizes the observational facts which allow us to reconstruct the chemical history of our Galaxy, in particular the abundances in stars and in terstellar medium; in the last decade, a great deal of observational work, mostly abundance determinations in stars in the solar vicinity, has shed light on the pro duction and distribution of chemical elements. Even more recently more abun dance data have accumulated for external galaxies at both low and high redshift, thus providing precious information on the chemical evolution of different types of galaxies and on the early stages of galaxy evolution.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 300 pp. Englisch.

Buch. Condición: Neu. Neuware -Dynamical systems theory is especially well-suited for determining the possible asymptotic states (at both early and late times) of cosmological models, particularly when the governing equations are a finite system of autonomous ordinary differential equations. In this book we discuss cosmological models as dynamical systems, with particular emphasis on applications in the early Universe. We point out the important role of self-similar models. We review the asymptotic properties of spatially homogeneous perfect fluid models in general relativity. We then discuss results concerning scalar field models with an exponential potential (both with and without barotropic matter). Finally, we discuss the dynamical properties of cosmological models derived from the string effective action. This book is a valuable source for all graduate students and professional astronomers who are interested in modern developments in cosmology.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 204 pp. Englisch.

Buch. Condición: Neu. Neuware -Aerobiology is the science that studies the biological component of the atmosphere and its effects on living systems and on the environment. This term was used for the first time in 1935, but the attention of scientists to the biological component of the atmosphere goes back to 1769, when the Italian biologist Spallanzani carried out a series of experiments that disproved the concept of spontaneous generation of life and proved the presence of viable microorganisms in the air. Aerobiology has marked characteristics of interdisciplinarity: its application fields range from respiratory diseases to the airborne outbreak of animal and vegetal diseases and to the biodegradation of substances and materials. The latter is the subject of this book. The purpose of aerobiological research applied to the conservation of cultural heritage is to evaluate the risk of alteration by airborne microorganisms of materials forming artefacts of historical, artistic and archaeological interest. Airborne spores and vegetative structures may develop on different substrates and may be a cause of degradation, in relation to the types of materials, the microclimatic situation and the pollution of the conservation environments. The qualitative and quantitative evaluation of the biological component of air, performed by means of targeted analysis campaigns, and of the characteristics of materials and environments, supplies indispensable information for the evaluation of the actual risk and the planning of interventions. This book is divided into four main parts.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 260 pp. Englisch.

Buch. Condición: Neu. Neuware -Change is an ongoing aspect of education and educators are always seeking alternative and effective approaches to it. The approaches, in the context of mathematics teacher education, discussed in this book are based on joint work between the individuals involved in the process. However, the factors that influence success within co-operative or collaborative change processes have not been the focus of scientific investigation. This book systematically investigates collaborative endeavours in a number of different domains of teacher education. The fifteen chapters in the four main sections of the book explore and reflect on a variety of issues related to collaborative mathematics teacher education practice and research - such as classroom coaching, mentoring or co-learning agreements - highlighting the evolution and implications of collaborative enterprises in different cultural settings. The resultant accounts should appeal to educational researchers, research students and practitioners around the world.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 288 pp. Englisch.

Sediment-water research is carried out all over the world within a variety of disciplines. The selected papers cover three main topics relating to assessment and/or restoration of disturbed watersheds, sediment-water linkages in terrestrial and aquatic environments and evaluation of sediment and ecological changes in marine and freshwater habitats. Innovative research in both developed and less developed countries is included. Both fundamental research, insight into applied research and system management are covered. The volume will also appeal to readers involved in sediment geochemistry and dynamics, aquatic habitats, water quality, aquatic ecology, river morphology, restoration techniques and catchment management.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 340 pp. Englisch.

Buch. Condición: Neu. Neuware -Functional Analysis is primarily concerned with the structure of infinite dimensional vector spaces and the transformations, which are frequently called operators, between such spaces. The elements of these vector spaces are usually functions with certain properties, which map one set into another. Functional analysis became one of the success stories of mathematics in the 20th century, in the search for generality and unification.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 704 pp. Englisch.

Buch. Condición: Neu.

Contributions by leading international mathematicians thoroughly discuss topics in: modules theory, integrally closed ideals and determinantal ideals, singularities in projective spaces and Castelnuovo-Mumford regularity, Groebner and SAGBI basis, and the use of the computer packages Bergman, CoCoA and SINGULAR.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 288 pp. Englisch.

Buch. Condición: Neu. Neuware -Keith Lehrer is one of the leading proponents of a coherence theory of knowledge that seeks to explain what it means to know in a characteristically human way. Central to his account are the pivotal role played by a principle of self-trust and his insistence that a sound epistemology must ultimately be ecumenical in nature, combining elements of internalism and externalism. The present book is an extensive, self-contained, up-to-date study of Lehrer's epistemological work. Covering all major aspects, it contains original contributions by some of the most distinguished specialists in the field, outgoing from the latest, significantly revised version of Lehrer's theory. All basic ideas are explained in an introductory chapter. Lehrer's extensive replies in a final chapter give unique access to his current epistemological thinking.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 368 pp. Englisch.

Buch. Condición: Neu. Neuware -On the most basic level, the articles brought together in the present volume aim to contribute to the charting of the (often subtle) links between the medieval and early modern periods in the fields of metaphysics, philosophical theology, and modal theory. In selecting this line of inquiry the volume is consciously intended to offer support for the stance that in the higher or speculative sciences no sharp divide exists between the later Middle Ages, on the one hand, and the Renaissance and early modern period, on the other. In adopting such an approach, one emphasizing historical continuity instead of discontinuity, the volume can be seen as challenging at least two related sets of convictions concerning the intellectual life of the period 1400-1700. First, prominent Renaissance and early modem thinkers portrayed their own intellectual projects and accomplishments as radical breaks with the scholasticism characteristic of the Middle Ages and also dominant in their own time; the volume to no small extent takes as its point of departure a reluctance - or, at least, a hesitation - to accept these bold claims. Second, a large part of nineteenth- and twentieth-century historiography has taken the Renaissance and early modern claims of fundamental innovation at face-value; in emphasizing the continuity that exists between the thought of the medieval and of the early modern periods, the volume is part of an attempt to offer a more balanced view of the intellectual production of the later period.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 356 pp. Englisch.

Buch. Condición: Neu. Neuware -The study of natural law theories in the early Enlightenment continues to be one of the most fruitful areas of research in early modern intellectual history. In recent years there have been substantial reassessments of Grotius, Pufendorf, Thomasius 1 and the whole university-based tradition associated with the Frühaujklärung. The appeal of the discourse of natural jurisprudence to groups and individuals operating outside conventional educational and political structures - such as the Huguenot diaspora - has also been highlighted Moreover the contextual understanding of the work of unambiguously major philosophers such as Hobbes and Kant - and its reception - has been greatly enhanced by studies that have sought to view them as 3 participants in rather than bystanders alongside the discourse of natural law. Thus thinkers previously not considered central to this discourse have been incorporated into it afresh. However, there is no danger of natural jurisprudence going unchallenged as the meta-discourse of political theory in this period, for recently new studies of the role of libertine and jansenist thought in shaping the priorities of the early Republic of Letters have challenged its position among the intellectual 4 achievements of the social and political theory of the early Enlightenment. This volume therefore offers a timely opportunity to reassess both the coherence of the concept of 'early Enlightenment' and the specific contribution of natural law theories to it.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 364 pp. Englisch.

Buch. Condición: Neu. Neuware -As we all know, weather radar came into existence during the Second World War when aircraft detection radars had their vision limited by echoes from rain bearing clouds. What was often considered to be of nuisance value by the air force personnel trying to locate enemy aircraft was seen as an opportunity by the weather men. Thus adversity in one field was converted into an opportunity in another. Since then weather radar has found myriad applications with the increased sophistication of technology and processing systems. It has now become an indispensable tool for the operational forecasters, cloud physicists and atmospheric scientists. The current generation radar is but a distant echo of the radars of the 1940s. As a result, its operation and maintenance have become very complex, like the technology it uses. Therefore, there is a definite requirement of focussing our special attention not only on the science of radar meteorology but also on its operational aspects. The present book,as pointed out by the author, attempts to fill this gap. The author has presented the subject with a balanced blend of science, technology and practice. The canvas is indeed very broad. Starting with the history of weather radar development the book goes on to discuss in a lucid style the physics of the atmosphere related to radar observation, radar technology, echo interpretation, different applications and finally attempts to look into the future to indicate potential new opportunities in this field.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 564 pp. Englisch.

Buch. Condición: Neu. Neuware -This book has grown out of my research interests in the theory of oper ator algebras, orthomodular structures and mathematical foundations of quantum theory. It is based on a series of lectures on measure theory on nonboolean operator structures which I prepared for Ph. D. students in Workshops on Measure Theory and Real Analysis in Italy (Gorizia 1999, Grado 2001) and which I have delivered at the conferences of the Interna tional Quantum Structures Association in Berlin 1996, Cesena 2001, and Vienna 2002. I have worked on these subjects in the framework of Prague's Semi nar on Mathematical Formalism of Quantum Theory founded by P. Ptak. Many results presented in the book were also obtained during my longer research stays abroad, in particular at the Department of Mathematics, Reading University, U. K. (1993) and at the Mathematical Institute of Er langen University, Germany (1996-1997, 2000 and 2003). Both the research activity and the work on the book was supported by a few international projects I participated in. I would like to acknowledge the support of European Community that supported my research stay in Reading University (Grant COST, Noncommutative Measure Theory and von Neumann Algebras, 1993). I am also very much grateful to the Alexan der von Humboldt Foundation, Bonn, for long-term support of my research and for awarding me the grants that enabled me work at Erlangen Uni versity in 1996-1997, 2000 and 2003.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 420 pp. Englisch.

This item is printed on demand - it takes 3-4 days longer - Neuware -This volume of the Argumentation Library contains a collection of twenty-six theor etical contributions to the study of argumentation. Together they provide an over view of recent developments in the theory of argumentation which does justice to the theoretical variety in the field. InAnyone Who Has a View, the subject of argu mentation is approached from different angles. Both the formal and informal logical approaches and the rhetorical and communicative approaches arc represented in various ways. We arc convinced that the collection of essays as a whole will be of interest not only to those engaged directly in the study of argumentation, but also to scholars from a variety of disciplines who arc interested in the recent developments in this field. The book opens with an essay by the informal logician Robert C. Pinto. For all the differences between them, James B. Freeman, Harvey Siegel, Ralph H. Johnson, Hans V. Hansen, and J. Anthony Blair are also prominent members of that move ment. Some informal logicians either eschew or simply do not use formal methods in their approach to argumentation, while others, such as David Hitchcock, use both formal and informal methods. Erik C.W.

This item is printed on demand - it takes 3-4 days longer - Neuware -This volume of NATO Science Series presents the Proceedings of the NATO Advances Research Workshop 'Optical Properties of 2D systems with interacting electrons' which was held at the Educational Centerofthe Ioffe Physico-Technical Institute in the period of June 13-16, 2002. More than 40 scientists from 14 countries participated and gave 24 lectures and 16 poster presentations. The main goal of theWorkshop was to bring togetherleading scientists working in the field of optical properties of correlated electron systems in semiconductor nanostructures and to organize a vital and informal discussions of newest results in the field. The location and the format of the Workshop provided an atmosphere of friendly and fruitful communications. It is important to note that the Workshop continued a series of meetings con cerning the same topic: Warsaw 1999, Wurzburg 2000 (NATO ARW), and Berlin 2001. The subject agenda of the ARW was focused on the following topics: Evolution of optical spectra from the excitonic peaks to the Fermi-edge singularity Negatively and positively charged excitons Reconstruction ofone-particle and collective excitation spectra with increase of the electron density (combined exciton-cyclotron resonance and shake-up processes) Effect of spatial inhomogeneity on the carrier interaction in nanostructures Spin-sensitive interaction and spin-spin interaction in confined systems Many-particle effects in semimagnetic semiconductor heterostructures. 300 pp. Englisch.

The scientific program covered a broad sweep of topics that are expected to remain of interest for many years to come. The topics in this volume complement those in earlier volumes (published by Kluwer) and should be of interest to many physicists. The main financial support for the Institute was provided by the Scientific Affairs Division of the North Atlantic Treaty Organization (NATO). The Institute was eo-sponsored by the U.S. Department of Energy (DOE), the Fermi National Accelerator Laboratory (Fermilab), the U.S. National Science Foundation (NSF), the Florida State Univer sity (FSU) - Offices of the Provost and the Dean of Arts and Sciences, the Department of Physics and the FSU High Energy Physics Group - and the Institute for Theoretical and Experimental Physics (ITEP, Moscow). 396 pp. Englisch.

Taschenbuch. Condición: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -This book presents the proceedings and the outcomes of the NATO Advanced Research Workshop (ARW) on Integrated Technologies for Environmental Monitoring and Information Production, which was held in Marmaris, Turkey, between September 10- 14, 200 I. With the contribution of 45 experts from 20 different countries, the ARW has provided the opportunity to resolve the basic conflicts that tend to arise between different disciplines associated with environmental data management and to promote understanding between experts on an international and multidisciplinary basis. The prevailing universal problem in environmental data management (EDM) systems is the significant incoherence between data collection procedures and the retrieval of information required by the users. This indicates the presence of problems still encountered in the realization of; (1) delineation of objectives, constraints, institutional aspects of EDM; (2) design of data collection networks; (3) statistical sampling; (4) physical sampling and presentation of data; (5) data processing and environmental databases; (6) reliability of data; (7) data analysis and transfer of data into information; and (8) data accessibility and data exchange at local, regional and global scales. Further problems stem from the lack of coherence between different disciplines involved in EDM, lack of coordination between responsible agencies on a country basis, and lack of coordination on an international level regarding the basic problems and relevant solutions that should be sought. 496 pp. Englisch.
