Buch. Etat : Neu. Neuware - St Antony's College, Oxford, was founded by Antonin Besse, a French entrepreneur who wanted to establish an international college in France. When this proved impossible, he turned to the University of Oxford, and the college opened its doors to students there in October 1950. Under the inspired leadership of William Deakin, St Antony's became a centre for postgraduate teaching, specializing in area studies. From the beginning it was the most deliberately inter-national of all Oxford colleges, and by 1999 its students were drawn from over forty different countries. It was also the first Oxford college to admit substantial numbers of both men and women. Based on archival materials and personal recollections, this book recounts the college's struggles to develop and fund its ambitious academic programmes. It also describes the changing lifestyle of its students in a period of expanding postgraduate education.…

Buch. Etat : Neu. Neuware - Speakers can get to know the meaning of any of indefinitely many sentences that they have never heard before. This statement encapsulates the problem of linguistic creativity, which lies at the core of philosophy of language and theoretical linguistics. It has also sparked off a considerable amount of work on the philosophy of mind. After establishing the failure of the familiar compositional approach to the problem, the book adopts a radically new start. It develops core elements of the later Wittgenstein's conception of philosophy, putting them to work to`dissolve' the problem, proving it ill-framed by clarifying the questions posing it and breaking the spell of mistaken analogies that inform it. This sharply focused monograph thus has a dual aim: coping with a crucial problem that turns out to be a lot tougher than is generally supposed, and presenting a precise and rigorous demonstration of an unfamiliar and exciting philosophical approach. Audience: Clearly written and lucidly structured, the book addresses professional philosophers and advanced undergraduates alike.…

Buch. Etat : Neu. Neuware - During the last 10 years, there has been a `revolution' in ecosystem modelling. The generality and predictive power of our models have increased in a way that was inconceivable 10 years ago. This book describes a new generation of practically useful models that predict as well as one can measure - if one measures well. And yet, they are driven by readily available driving variables and have a general structure that applies to most types of pollutants in aquatic systems. The major reason for this development is, in fact, the Chernobyl accident. Large quantities of radiocesium were released in April/May 1986 as a pulse. To follow the pulse of radiocesium through ecosystem pathways has meant that important fluxes and mechanisms, i.e., ecosystem structures, have been revealed. It is important to stress that many of these new structures and equations are valid not just for radiocesium, but for most types of contaminants, e.g. for metals, nutrients and organics. This means that the models, methods (of building and testing models) and equations described in this book for lakes and coastal areas should be of great interest also to other ecosystem modellers. This book will be of considerable interest to: students in radioecology, geosciences and biology; environmental engineers; consultants; administrators and scientists interested in the spread, biouptake and ecosystem effects of chemical pollutants in aquatic ecosystems.…

Buch. Etat : Neu. Neuware - According to the neutrality thesis, in designing state policies governments should not allow themselves to be informed by any particular conceptions of the good life. The aim of this book is to contribute to the debate about this thesis in two specific ways. Firstly, the limits of acceptable state perfectionism are examined, not on a general level but by reference to some particular concerns of government policy; transgenic animals, future generations, the promotion of the arts, minority cultures, the allocation of scarce health care resources, the integration of mentally handicapped people into the community, and the expression of national identities. Secondly, the book as a whole evaluates the argument that the government has a special task to produce or to maintain intrinsically collective aspects of the good life, because these are to be seen as public goods.…

Buch. Etat : Neu. Neuware - Medicine's crucial concern with health is perennial, but its reflection, concepts, means change with the advance of science and social life. We present here a fascinating panorama of current medical discussions with their philosophical underpinnings, and queries as they have evolved from the past. The role of Tymieniecka's phenomenology of life is brought forth as the system of philosophical reference.…

Taschenbuch. Etat : Neu. Neuware - Two decades have passed since the mechanisms of protein synthesis became well enough understood to permit the genetic modification oforganisms. An impressive amount of new knowledge has emerged from the new technology, but much ofthe promise of20years ago has notyet been fulfilled. In biotechnology, efforts to increase the yields of commercially valuable metabolites have been less successful than ex pected, and when they have succeeded it has often been as much from selective breeding as from new methods. The cell is more complicated than what is presented in the classical teaching of biochemistry, it contains more structure than was dreamed of 20 years ago, and the behaviour ofany systemofenzymes is more elaborate than can be explained in terms ofa single supposedly rate-limiting enzyme. Even if classical enzymology and meta bolism may have seemed rather unfashionable during the rise ofmolecular biology, they remain central to any modification ofthe metabolic behaviour oforganisms. As such modification is essential in much ofbiotechnology and drug development, bio technologists can only ignore these topics at their peril.…

Buch. Etat : Neu. Neuware - The three decades which have followed the publication of Heinz Neudecker's seminal paper `Some Theorems on Matrix Differentiation with Special Reference to Kronecker Products' in the Journal of the American Statistical Association (1969) have witnessed the growing influence of matrix analysis in many scientific disciplines. Amongst these are the disciplines to which Neudecker has contributed directly - namely econometrics, economics, psychometrics and multivariate analysis. This book aims to illustrate how powerful the tools of matrix analysis have become as weapons in the statistician's armoury. The majority of its chapters are concerned primarily with theoretical innovations, but all of them have applications in view, and some of them contain extensive illustrations of the applied techniques. This book will provide research workers and graduate students with a cross-section of innovative work in the fields of matrix methods and multivariate statistical analysis. It should be of interest to students and practitioners in a wide range of subjects which rely upon modern methods of statistical analysis. The contributors to the book are themselves practitioners of a wide range of subjects including econometrics, psychometrics, educational statistics, computation methods and electrical engineering, but they find a common ground in the methods which are represented in the book. It is envisaged that the book will serve as an important work of reference and as a source of inspiration for some years to come.…

Buch. Etat : Neu. Neuware - Space-Time Processing for CDMA Mobile Communications is one of the first books to: bring together spatial/temporal channel models and analytic performance evaluation techniques; establish a link between smart antenna systems and advanced receiver design techniques; treat smart antennas specifically for UMTS-like communication systems, with applicable simulations and calculations; supply code with Matlab® GUI so readers can run or modify existing simulations or create new ones. The field of smart antenna technology or, more generally, space-time processing is rapidly becoming one of the most promising areas of mobile communications, especially regarding the development of the first practical third-generation mobile communication systems. The authors have addressed many of the most basic questions relating to the use of space-time processing in CDMA-based third-generation systems and have presented models for the integration of space-time processing, error correction coding, and multi-user detection techniques. Included is extensive background information on cellular systems, antenna array theory, smart antenna techniques, performance of basic space-time processors and advanced space-time processors. The book also includes an extensive simulation program written in Matlab®. The simulation code implements both the uplink and the downlink of a UMTS-like communication system. This provides multiple options for simulating system performance using a variety of channel models as well as receiver structures. Space-Time Processing for CDMA Mobile Communications will be an invaluable reference work for engineers and researchers, and a useful source for design engineers enabling them to understand the implications of adding space-time processing systems to CDMA-based communication systems.…

Taschenbuch. Etat : Neu. Neuware - The impetus for this volume began with our research in the 1980's involving serial neuropsychological evaluation with various patient populations. At that time, reports on the practice effects associated with routinely utilized clinical neuropsychological instruments were sparse. While test-retest data were available for almost all assessment instruments, this was usually in the form of correlation coefficients and not changes in mean performance between or across assessment periods (see McCaffrey & Westervelt, 1995 for a detailed discussion of these and related issues). Clinical neuropsychological practitioners had few guidelines to assist them in determining if a change in a patient's performance across assessments was due to an intervention, maturation, practice effects, or a combination of factors. This volume represents our efforts at reviewing the literature between 1970 and 1998 and extracting the reported information on practice effects. The tables include the assessment instrument used, information on the subject/patient groups, the sample size (n}, gender, age, intervention, interval between the assessments, scores at both assessment points, and the citation. Those studies that reported data on more than two assessment points are indicated by a notation~ however, any data beyond the second assessment are not reported and the interested reader should refer to the original article. The tables are arranged alphabetically for the most widely used assessment instruments. Those instruments for which there was limited data on practice effects are grouped by 'domain' (e. g.…

Buch. Etat : Neu. Neuware - This book is the proceedings of the Falk Workshop on `Bile Acids in Hepatobiliary Disease', which took place at the Royal Society of Medicine (RSM) in London, UK, on 29-30 March 1999, and was held in association with the Section of Measurement in Medicine at the RSM. The main interest in bile acid therapy has been recently in cholestatic liver disease. The proceedings of the workshop not only discusses this, but moves on to examine its possible use in alcoholic liver disease, and moves back to re-examine its role in biliary disease. Leading world experts attempt to define its mechanism of action, and the current role of other non-surgical treatments in biliary disease. The physiology and pathogenesis of cholestatic and alcoholic liver disease and cholesterol gallstone disease is also examined.…

Buch. Etat : Neu. Neuware - Noninvasive electrocardiographic monitoring is a fundamental part of cardiology. Depending on continuous improvements and developments of new technologies, these methods are essential for diagnosis and risk stratification of patients. The rapid changes in the capabilities, technologies and diagnostic values of the different methods force us to update our knowledge continuously. This book offers a comprehensive overview of the current state and future developments in the field of noninvasive electrocardiographic monitoring techniques. In addition, related fields such as magnetocardiography, newer signal detection and analysis techniques as well as ambulatory blood pressure monitoring are reported. The different methods are discussed with regard to methodological aspects, latest technical developments and clinical value of results. Furthermore, review articles focus on the autonomic nervous system, monitoring of ischemic heart disease, quality control and standardization of monitoring techniques. A group of international experts in science and clinical practice have contributed to this book, which is supported by the International Society for Holter and Noninvasive Electrocardiography (ISHNE). The book is addressed to clinical and academic cardiologists as well as scientists.…

Buch. Etat : Neu. Neuware - Accurate diagnosis of arrhythmias is the goal of this volume. Before the clinician can accurately classify the multiple permutations of cardiac rhythm encountered in daily practice, several essential preconditions must be met. At the most basic level, the clinician must know the diagnostic criteria for each rhythm. Without a clear understanding of these criteria, an accurate differential diagnosis is impossible, and without accurate diagnosis, correct intervention is a mere matter of chance. A second precondition of accurate rhythm diagnosis is an understanding of the mechanism of arrhythmias. Not uncommonly, two or more arrhythmic mechanisms coexist, confronting the clinician with a baffling mixture of apparently unrelated complexes and intervals. Without an understanding of the various arrhythmic mechanisms, simple and complex, the tangled skein of data can never be unraveled. Finally accurate arrhythmia diagnosis depends on skill attained through practice. The competent electrocardiographer combines the skills of precise measurement and rational application of logic with broad theoretical knowledge. The pleasure of electrocardiography is seeing through the surface appearance to the inner workings. Interpretation of Cardiac Arrhythmias presupposes no prior knowledge of arrhythmias, and progresses from basic to the complex. The didactic sections focus extensively on the mechanism of arrhythmia, using laddergrams and other diagramatic devices to help the student visualize what is happening with the cardiac conduction system. Extensive self-assessment sections enable students to apply critical skills and test their grasp of the diagnostic criteria.…

Buch. Etat : Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -From its discovery in the Columbia River three years ago, reporter Roger Downey has chronicled the epic adventures of the skeleton called 'Kennewick Man': first as a pretext for a media feeding-frenzy, then as the centerpiece of a legal circus pitting celebrated scientists against Native Americans, the Corps of Engineers, and the Clinton White House, finally, at long last, as an object of rational scientific study. The saga of Kennewick Man offers abundant opportunity to explore today's rapidly-changing scientific theories about how the Americas first came to be settled, and by whom. But it also casts much light on the deep divisions within the fields of anthropology and archeology concerning the role of politics and race in the pursuit of scientific goals, what constitutes ethical procedure in dealing with ancient human remains and living individuals, and the very purpose and direction of the scientific enterprise itself. With an easy style that keeps you hooked from beginning to end, Downey describes the major players in this continuing debate and details the controversial scientific, religious, and political arguments surrounding Kennewick Man. 224 pp. Englisch.…

Taschenbuch. Etat : Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -It is now accepted that the first cells derived from simpler 'objects', and that their descendants became more and more complicated and ordered until their evolutionary transformation into modern cells, namely, cells endowed with the same basic structures and mechanisms as those existing today. Although the appearance of the first modern cells goes back at least two billion years, many scholars believe that it occurred almost four billion years ago. In that case, the Earth's formation, which took place quite quickly about 4. 6 billion years ago, is in close proximity to the originoflife. There is disagreement not only about the moment ofappearance ofmodern cells, but also as to their early evolution. Ideas on the first steps in cellular evolution vary considerably, and our present knowledge is so limited as to be little more than vacuous. Why discuss it then Precisely because it is an empty space that needs to be filled! Does it make sense only to discuss things which are well-known and well documented Is this the best way to interpret that spirit of exploration of the unknown which is at the very heartofscientific endeavor The idea that it is idle to venture into fields which are poorly documented has been long supported, even in cases similar to those dealt with here, for example, the evolutionary phases which took place before the first cell. 184 pp. Englisch. …

This item is printed on demand - it takes 3-4 days longer - Neuware -Whereas several areas of biocatalysis - in particular the use of easy-to-use hydrolases such as proteases, esterases and lipases - are sufficiently well researched to be applied in every standard laboratory, other types of enzymes are still waiting to be discovered with respect to their applicability in organic-chemistry transformations on a preparative scale. This latter point is stressed in this volume, which concentrates on the 'newcomer-enzymes' which show great synthetic potential. 232 pp. Englisch.…

This item is printed on demand - it takes 3-4 days longer - Neuware -requiring the adaptation of probabilistic maps to design ground motions; and (d) the generalization of design parameters to locations where there is little seismic history. Maximum displacements, velocities, and, based on the European Build ing Code EC8, design ground acceleration maps have thus been produced by ZivCic et al. for Slovenia, Markuic et al. for Croatia, Bus et al. for Hungary, and Radulian et al. for Romania. The last two contributions in the volume are dedicated to studies of local site effects that could affect the microzonation of large urban areas. Moldoveanu et al. employed a technique based on the modal summation and finite dif ferences to calculate the expected ground motion in the capital city of Bucha rest due to large intermediate-depth Vrancea earthquakes. Their results outline that the presence of alluvial sediments and the possible variation of event scenario require the use of all three components of motion for a reliable determination of the seismic input. The study of Marmureanu et al. , more limited in scope, offers a laboratory analysis of the attenuation effects for sur face layers. The authors confirm that seismic attenuation in sedimentary layers is a function of the strain levels induced by large earthquakes, and find that the quality factor is nearly constant over a relatively wide frequency range, between 7 and 100 Hz. 280 pp. Englisch. …

Taschenbuch. Etat : Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -Many biological systems still hold a variety of very desirable molecular properties that so far cannot be matched by artifical analogs. Learning about the principles and tricks used by nature may provide access to novel nanostructures, improved catalysts for the functionalization of hydrocarbon compounds or may enable catalytic C-C bond formation under environmentally benign conditions. This volume recapitulates the state of the art in those sectors of bioorganic chemistry that, rather than mimick the natural example, aim to utilize the underlying principles for useful applications. 204 pp. Englisch.…

Taschenbuch. Etat : Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -Intelligent agents are one of the most important developments in computer science in the 1990s. Agents are of interest in many important application areas, ranging from human-computer interaction to industrial process control. The ATAL workshop series aims to bring together researchers interested in the core aspects of agent technology. Speci cally, ATAL addresses issues such as th- ries of agency, software architectures for intelligent agents, methodologies and programming languages for realizing agents, and software tools for developing and evaluating agent systems. One of the strengths of the ATAL workshop series is its emphasis on the synergies between theories, infrastructures, architectures, methodologies, formal methods, and languages.

Buch. Etat : Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -Simplicity theory is an extension of stability theory to a wider class of structures, containing, among others, the random graph, pseudo-finite fields, and fields with a generic automorphism. Following Kim's proof of `forking symmetry' which implies a good behaviour of model-theoretic independence, this area of model theory has been a field of intense study. It has necessitated the development of some important new tools, most notably the model-theoretic treatment of hyperimaginaries (classes modulo type-definable equivalence relations). It thus provides a general notion of independence (and of rank in the supersimple case) applicable to a wide class of algebraic structures. The basic theory of forking independence is developed, and its properties in a simple structure are analyzed. No prior knowledge of stability theory is assumed; in fact many stability-theoretic results follow either from more general propositions, or are developed in side remarks. Audience: This book is intended both as an introduction to simplicity theory accessible to graduate students with some knowledge of model theory, and as a reference work for research in the field. 276 pp. Englisch.…

Taschenbuch. Etat : Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -SAC 99 was the sixth in a series of annual workshops on Selected Areas in Cryptography. Previous workshops were held at Carleton University in Ottawa (1995 and 1997) and at Queen s University in Kingston (1994, 1996, and 1998). The intent of the annual workshop is to provide a relaxed atmosphere in which researchers in cryptography can present and discuss new work on selected areas of current interest. The themes for the SAC 99 workshop were: { Design and Analysis of Symmetric Key Cryptosystems { E cient Implementations of Cryptographic Systems { Cryptographic Solutions for Web/Internet Security The timing of the workshop was particularly fortuitous as the announcement by NIST of the v e nalists for AES coincided with the rst morning of the workshop, precipitating lively discussion on the merits of the selection! A total of 29 papers were submitted to SAC 99 and, after a review process that had all papers reviewed by at least 3 referees, 17 were accepted and p- sented. As well, two invited presentations were given: one by Miles Smid from NIST entitled From DES to AES: Twenty Years of Government Initiatives in Cryptography'and the other by Mike Reiter from Bell Labs entitled Password Hardening with Applications to VPN Security'.
