Buch. Condizione: Neu. Neuware - All except three of the papers in this volume were presented at the colloquium on 'L'Ontologie formelle aujourd'hui', Geneva, 3-5 June 1988. The three exceptions, the papers by David Armstrong, Uwe Meixner and Wolfgang Lenzen, were presented at the colloquium on 'Properties', Zinal, June 1-3, 1990. It was, incidentally, at the second of these two colloquia that the European Society for Analytic Philosophy came into being. The fathers of analytic philosophy - Moore and Russell - were in no doubt that ontology or metaphysics as well as the topics oflanguage, truth and logic constituted the core subject-matter of their 'analytic realism', 1 for the task of metaphysics as they conceived things was the description of 2 the world. And logic and ontology are indissolubly linked in the system of the grandfather of analytic philosophy, Frege. After the Golden Age of analytic philosophy - in Cambridge and Austria - opposition to realism as well as the 'linguistic turn' contributed for a long time to the eclipse of ontology. 3 Thanks in large measure to the work of some of the senior contributors to the present volume - Roderick Chisholm, Herbert Hochberg, David Armstrong and Karel Lambert - ontology and metaphysics now enjoy once again the central position they occupied some eighty years ago in the heyday of analytic philosophy.…

Buch. Condizione: Neu. Neuware - Rutgers University launched WINLAB in 1989, just as the communications industry, the Federal government, and the financial community in the United States, were waking up to the growing public appetite for wireless communications and to the shortage of technology to feed it. The secret was already out in Europe, where no fewer than three new cordless and cellular systems were progressing from drawing board to laboratory to factory to consumers. In July 1989, the FCC held a well-attended tutorial that turned into a debate over whether second generation British or Swedish technology held the key to mass-market personal communications. Many in the audience wondered whether United States technology was out of the picture. Technology uncertainties are more acute in wireless communications than in any other information service. For example multi-gigabit optical fiber communications have followed an orderly progression from basic science leading to technology, which in turn stimulated standards, and then commercial products. Eventually applications will be found and industry and society at large will reap the benefits. By contrast, the applications of wireless communications are apparent to an eager public. A large market exists but is held in check by a shortage of capacity. The demand has led the cellular industry to formulate standards for advanced systems before the technology is in place to implement them. Everyone holds their breath waiting to observe performance of the first products. Gaps in basic science add to the uncertainty and forestall the resolution of technological debates.…

Buch. Condizione: Neu. Neuware - The Showa Era in Japan commenced in December 1926, when Emperor Showa ascended the Throne, and came to an end in January 1989, when His Majesty passed away, ushering in the new Heisei Era. The Showa Era was marked by drastic changes in the economy, society, and political and legal sys tems, which brought about an ebb and flow in criminality and precipitated various criminal policies. From an economical, political, and criminological perspective, the Showa Era stands out as a remarkable period in Japanese his tory. The Research and Training Institute of the Ministry of Justice, which has annually published the White Paper on Crime in Japan since 1960, received Cabinet approval to introduce a special topic section, 'Criminal Policy in Sho wa' in the White Paper for 1989, which was published in October the same year. This White Paper is the first comprehensive publication that deals not only with the crime situation but also with the various activities of the criminal justice system, including the police, public prosecutors' offices, courts, correctional institutions, and probation and parole supervision organisations for 63 years.…

Buch. Condizione: Neu. Neuware - THE PLACE OF PHILOSOPHY IN COGNITIVE SCIENCE During the last few years, many books have been published and many meetings have been held on Cognitive Science. A cursory review of their contents shows such a diversity of topics and approaches that one might well infer that there are no genuine criteria for classifying a paper or a lecture as a contribution to Cognitive Science. It is as though the only criterion is to have appeared in a book or in the programme of a meeting or title we can find the expression ' . . . Cognitive Science' in whose name or something like that. Perhaps this situation is due to the (relative) youth of the field, which is seeking its own identity, still involved in a process of formation and consolidation within the scientific community; but there are actually deep disagreements about how a science of the mind should be worked out, including how to understand its own subject, that is, 'the mind. 'While for some the term makes reference to a set of phenomena impossible to grasp by any scientific approach, for others 'the mind' would be a sort of myth, and the mental terms await elimination by other more handy and empirically tractable terms.…

Buch. Condizione: Neu. Neuware - The field of Computational Economics is a fast growing area. Due to the limitations in analytical modeling, more and more researchers apply numerical methods as a means of problem solving. In tum these quantitative results can be used to make qualitative statements. This volume of the Advanced Series in Theoretical and Applied and Econometrics comprises a selected number of papers in the field of computational economics presented at the Annual Meeting of the Society Economic Dynamics and Control held in Minneapolis, June 1990. The volume covers ten papers dealing with computational issues in Econo metrics, Economics and Optimization. The first five papers in these proceedings are dedicated to numerical issues in econometric estimation. The following three papers are concerned with computational issues in model solving and optimization. The last two papers highlight some numerical techniques for solving micro models. We are sure that Computational Economics will become an important new trend in Economics in the coming decade. Hopefully this volume can be one of the first contributions highlighting this new trend.

Buch. Condizione: Neu. Neuware - The use oflasers has entered almost every facet of medicine and biology. Therefore, it is to be expected that the reviews contained in this vol urne will reflect this diversity. As dinical acceptance has grown with various diagnostic and therapeutic applications, so has the need for a more thorough understanding of the theoretical background for each. This is especially true where a correlation is to be made between the theoretical background and the experimental data. It is only in this way that we can attain the optimal form of any therapy. The basic coupling ofenergy into biological tissue and its conversion into heat is characterized by many parameters. One ofthe most important is pulse duration. The review by Bimgruber in Chapter 6 shows how our knowledge ofthis parameter has been extended.The need for a more basic understanding of the interaction of electromagnetic energy with various kinds of materials has led to investigations on the nature of plasmas their stability and instability,and how theyexist. Docchio reviews the factors that cause them to occur at a specific locale and then to move away from that site. The availabilityofmany types ofoptical fibers has extended our ability to deliver laser energy from various types oflasers into almost anyselected location. This is particularly useful in medicine, where less invasive ap proaches to surgery and diagnosis are always helpful. However, as Rol and his colleagues explain, the power-handling capabilities ofoptical fibers limit many applications, particularly for short-duration, high-peak-power laser pulses.…

Buch. Condizione: Neu. Neuware - The developments in mass spectrometry over the past fifteen years have been impressive in their implications in bioanalytical chemistry. The achievements begin with the inventions of Cf-252 Plasma Desorption Mass Spectrometry by Macfarlane and Fourier Transform Mass Spectrometry by Comisarow and Marshall in the mid 1970s. The former showed the feasibility of producing large gas-phase ions from large biomolecules whereas the latter enhanced the capabilities for ion trapping especially in analytical mass spectrometry. A major achievement was the development by Barber of Fast Atom Bombardment (FAB) mass spectrometry, an advance that heralded a new era in biological mass spectrometry. Contemporary and routine instruments such as magnetic sectors and quadrupoles were rapidly adapted to F AB, and nearly the entire universe of small molecules became amenable to study by mass spectrometry. The introduction of FAB also paved the way for improvement of instrument capability. For example, the upper mass limit of magnet sector mass spectrometers was increased by nearly an order of magnitude by the instrument manufacturers. Furthermore, the technique of tandem mass spectrometry (MS/MS) was given new meaning because important structural information for biomolecules could now be produced for ions introduced by FAB into the tandem instrument. The evolution of MS/MS continues today with the development of ion traps, time-of-flight, and sector instruments equipped with array detection.…

Taschenbuch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -The interplay between the spectral theory of Schr|dingeroperators and probabilistic considerations forms the maintheme of these notes, written for the non-specialist readerand intended to provide a brief and elementaryintroductionto this field. An attempt is made to show basic ideas instatu nascendi and to follow their evaluation from simplebeginnings through to more advanced results. The term'genetic' in the title refers to this proceedure. The authorconcentrates on 2 topics which, in the history of thesubject, have been of major conceptual importance - on theone hand the Laplacian is a random medium and the left endof its spectrum (leading to large deviation problems forBrownian motion and the link to thenotion of entropy) andon the other, Schr|dinger operators with general ergodicpotentials in one-dimensional space. Ideas and concepts areexplained in the simplest, possible setting and by means ofa few characteristic problems with heuristic argumentspreceding rigorous proofs. 136 pp. Englisch.…

Taschenbuch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -The approach to the Cauchy problem taken here by the authorsis based on theuse of Fourier integral operators with acomplex-valued phase function, which is a time functionchosen suitably according to the geometry of the multiplecharacteristics. The correctness of the Cauchy problem inthe Gevrey classes for operators with hyperbolic principalpart is shown in the first part. In the second part, thecorrectness of the Cauchy problem for effectively hyperbolicoperators is proved with a precise estimate of the loss ofderivatives. This method can be applied to other (non)hyperbolic problems. The text is based on a course oflectures given for graduate students but will be of interestto researchers interested in hyperbolic partial differentialequations. In the latter part the reader is expected to befamiliar with some theory of pseudo-differential operators. 180 pp. Englisch.…

Taschenbuch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -This book concerns the question of how the solution of asystem of ODE's varies when the differential equationvaries. The goal is to give nonzero asymptotic expansionsfor the solution in terms of a parameter expressing how somecoefficients go to infinity. A particular classof familiesof equations is considered, where the answer exhibits a newkind of behavior not seen in most work known until now. Thetechniques include Laplace transform and the method ofstationary phase, and a combinatorial technique forestimating the contributions of terms in an infinite seriesexpansion for the solution. Addressed primarily toresearchers inalgebraic geometry, ordinary differentialequations and complex analysis, the book will also be ofinterest to applied mathematicians working on asymptotics ofsingular perturbations and numerical solution of ODE's. 148 pp. Englisch.…

Taschenbuch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -In this book overlapping generations economies are analysedfrom a game theoretical point of view and the socialacceptability of consumption allocations is studied ininfinite horizon models of pure exchange economieswithagents with finite lifetimes who behave cooperatively. Thecore of such economies and its relation with competitiveequilibria, both walrasian and monetary and the essentialcharacteristics of the overlapping generations model areexamined.The author defines the problem of trust in intertemporalconsumption allocations as a question of belonging or not tothe core of economy and provides a full characterization ofthe core allocations for n-goods pure exchange economieswith one agent per generation: a consumption allocationbelongs to the core if and only it is Pareto optimal andSequentially Individually Rational. From this it followsthat for one commodity economies no consumption allocationinvolving intertemporal transfers can belong to the core ofthe economy. In other words, no monetary equilibrium issocially viable. This result is no longer true for manygoods models. For that case it is demonstrated that thereexist bounds on the real value of equilibrium moneypurchases beyond which monetary equilibria are not sociallyviableand with many agents in every generation it is shownthat as the economy becomes large and monetary (as well asIOU) equilibria become eventually excluded from the core ofthe economy. These results provide an analytical rationalefor the fact that in most countries fiat money is legaltender. 220 pp. Englisch.…

Taschenbuch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -This volume is dedicated to Professor Ullrich Trendelenburg. It contains the proceedings of a symposium which was held in his honour on the occasion of his retirement and took place March 22-24, 1991 in Wiirzburg. Ullrich Trendelenburg was the head of the Department of Pharmacology at Wiirzburg University from 1968 till the end of March 1991. He is famous internationally for his contributions to the physiology and pharmacology of the autonomic nervous system, and his impact on pharmacology in general throughout the world has been outstanding. The various phases of his life and his career have been delineated recently by Youdim and Riederer (Journal of Neural Transmission; Suppl. 32, 1990). The articles included in this volume reflect a considerable range of current research work dealing with various aspects of neuropharmacology, i. e. , the field of research Ullrich Trendelenburg has influenced most. One or more authors of each chapter are either former or present students and coworkers or close friends of Ullrich Trendelenburg. The first section is devoted to the synthesis and metabolism of catecholamines as well as to the mechanisms by which amine transmitters are removed from the extracellular fluid; three chapters deal with the two types of extraneuronal uptake of catecholamines. The second section concentrates on the release of catecholamines in the peripheral and the central nervous system, the regulation of transmitter release and the noradrenaline-ATP co-transmis sion. The third section deals with the pharmacology of various receptors, including agrenoceptors, adenosine, 5-HT and glutamate receptors. 236 pp. Englisch.…

Taschenbuch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -This monograph presents foundations for a constrainedlogic scheme treating constraints as a very general form ofrestricted quantifiers. The constraints - or quantifierrestrictions - are taken from a general constraint systemconsisting of constraint theory and a set of distinguishedconstraints.The book provides a calculus for this constrained logicbased on a generalization of Robinson's resolutionprinciple. Technically, the unification procedure of theresolution rule is replaced by suitable constraint-solvingmethods. The calculus is proven sound and complete for therefutation of sets of constrained clauses. Using a new andelegant generalization of the notion ofa ground instance,the proof technique is a straightforward adaptation of theclassical proof technique.The author demonstrates that the constrained logic schemecan be instantiated by well-known sorted logics orequational theories and also by extensions of predicatelogics with general equational constraints or conceptdescription languages. 132 pp. Englisch.…

This item is printed on demand - it takes 3-4 days longer - Neuware -The aim of the Technical Advisory Committee, in planning the c~:Dtent of this meeting, was to illustrate the range of separation processes in which the use of membranes was practical and effective at an industrial scale. As Professor Strathmann reveals, the market for process equipment built around membranes is now worth about $5x1(f annually, and it seemed important to review this technology, and to point the direction of future technical advances. All but the most critical reader should find some items of interest. The Committee would admit to not fulftlling all of thier aims, although those delegates who attended the meeting in Edinburgh judged it a success. In the event it provided representative examples of processes from the food and beverage industry, from water treatment, and from the chemical industry, of which the removal of alcohol from fermented beverages, shipboard desalination and solvent recovery are three. The major uses of charged membranes and sterile processes are not covered, nor 9 is the largest market, $1.2x10 annually, for artificial kidney dialysis. However, it is interesting to see artificial kidney now finding an alternative use as a reactor for the production of monoclonal antibodies. We are also reminded by Professor Michel of the importance and efficiency of natural membranes in the kidney under conditions where fouling is crucial to their performance and enhances their selectivity. 432 pp. Englisch.…

Taschenbuch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -Fishes live in a world that is unfamiliar to us. Although we may make or even more advanced brief visits to this other world using a snorkel, scuba diving equipment, we can never become a part of it. Yet, an understanding of fish ecology requires an awareness of the relationships between fishes and their environment. The purpose of this book is to introduce the ecology of fishes by describing the inter-relationships between fishes and the aquatic habitats they occupy. The book can be read in complementary ways. A sequential reading, chapter by chapter, covers the main themes of ecology, including habitat use, species interactions, migration, feeding, population dynamics and reproduction in relation to the major habitats occupied by fishes. An alternative reading selects a particular sort of habitat, such as rivers, and, by using the index and skipping from chapter to chapter, builds up a picture of the ecology of fishes living in that habitat. The text is written for advanced students. Its emphasis is on descriptive rather than quantitative ecology. It is assumed that the reader will be familiar with the basic biology of fishes, acquired from a text such as The Biology of Fishes (Bone and Marshall, 1982) also published in the Tertiary Level Biology series. I would like to thank Dr J. D. Fish and two anonymous reviewers who, within a tight time-schedule, tried to improve the text. Any mistakes and shortcomings are my contribution. 228 pp. Englisch. …

This item is printed on demand - it takes 3-4 days longer - Neuware -This volume is the proceedings of the Second InternationalConference on Deductive and Object-Oriented Databases(DOOD). During the last decade, deductive andobject-oriented systems have received a great deal ofattention, but for the most part these two fields wereevolving independently of each other. Today there is a largebody of work suggesting that the deductive andobject-oriented paradigms complement each other.The object-oriented paradigm is characterized by its view ofthe data, whereby information is grouped around objects withcomplex internal structure accessed via methods. Thedeclarative paradigm is centered around the idea that datamanipulation must be done through a declarative, logic-basedlanguage. It is hoped that these two aspects, broughttogether in one system, will provide an integrated frameworkfora new database technology.The DOOD conference brings together researchers anddevelopers in the fields of deductive and object-orienteddatabases to stimulate technical discussion and acceleratethe integration of the two technologies.
