Buch. Condizione: Neu. Neuware - The developments in linguistic theory over the last three decades have given us a better understanding of the formal properties of language. However, as the truism goes, language does not exist in a vacuum. It in teracts with a cognitive system that involves much more than language and functions as the primary instrument of human communication. A theory of language must, therefore, be based on an integration of its for mal properties with its cognitive and communicative dimensions. The present work is offered as the modest contribution to this research paradigm. This book is a revised and slightly enlarged version of my doctoral thesis submitted to the University of Illinois at Urbana-Champaign. In writing the original version, I had the privilege of working with Professor Charles E. Osgood, who is widely recognized as the founder and one of the leading figures of modern psycholinguistics. I have benefited from ex tensive and stimulating discussions with him, not only on this topic but in the development of his theory of language performance in general (see his Lectures on Language Performance, 1980, in this series). However, the re sponsibility for the particular formulations of the theory, hypotheses, in terpretations, and conclusions found in this work-which have been in fluenced, no doubt, by my training as a linguist, rather than as a psychologist-are my own.…

Buch. Condizione: Neu. Neuware - This monograph is a contribution to the study of the identification problem: the problem of identifying an item from a known class us ing positive and negative examples. This problem is considered to be an important component of the process of inductive learning, and as such has been studied extensively. In the overview we shall explain the objectives of this work and its place in the overall fabric of learning research. Context. Learning occurs in many forms; the only form we are treat ing here is inductive learning, roughly characterized as the process of forming general concepts from specific examples. Computer Science has found three basic approaches to this problem: - Select a specific learning task, possibly part of a larger task, and construct a computer program to solve that task . - Study cognitive models of learning in humans and extrapolate from them general principles to explain learning behavior. Then construct machine programs to test and illustrate these models. xi Xll PREFACE - Formulate a mathematical theory to capture key features of the induction process. This work belongs to the third category. The various studies of learning utilize training examples (data) in different ways. The three principal ones are: - Similarity-based (or empirical) learning, in which a collection of examples is used to select an explanation from a class of possible rules.…

Buch. Condizione: Neu. Neuware - Over two centuries ago, oxygen was discovered as 'air vital': the component of the earth's atmosphere necessary for life. Less than five years after this discovery, it was found that oxygen was both a life-sustaining and life threatening inhalant as it plays a role in the two extremes of the animal kingdom: life and death. In the subse quent years, we have made major strides in understanding the role of oxygen in maintaining life and volumes of information are now available on this topic. Our knowledge of the contribution of oxygen in cellular dysfunction and cell death which for the most part had lagged behind has begun to catch up. The deleterious ef fects of oxygen radicals and activated oxygen species on a variety of biological systems have now been described. Recently attention has also been focused on the toxic effects of oxygen on the cardiovascular system. The major aim of the present treatise is to offer an integrated view of the pathophysiological aspects of oxygen toxicity in the heart and blood vessels coupled with a review of therapeutic approaches (hopes ) with free radical scavengers and antioxidants. Internationally known expert investigators provide a concise and critical review on the topic of their expertise which also contains data from their own research.…

Buch. Condizione: Neu. Neuware - Cardiovascular drug therapy has markedly progressed in the recent decades. Not only have new drugs been introduced to clinical practice, but new classes of drugs have been developed. While in 1960 the practicing cardiolo gist had a selection of about only ten drugs, in 1987 about 150 drugs are routinely used in cardiovascular diseases. Elderly patients, however, usually do not enjoy the full benefit of this progress. This might be due to lack of knowledge, a conservative approach, or the worldwide tendency not to try new drugs in the elderly. It is now clear that the majority of patients that will be treated in car diovascular clinics will be, in the near future, elderly patients. Even now, elderly patients form about one-third of the patients with cardiovascular diseases. These patients are approached, however, according to criteria devel oped for younger populations. This is despite the fact that elderly patients differ from younger ones in most aspects, including pathology, epidemiol ogy, pathophysiology, diagnostic approach, management, pharmacology, pharmacokinetics, rehabilitation, and supportive treatment. It is the purpose of this book to present to the clinician all drugs with which there is clinical experience in the elderly or which might be potentially useful for the elderly with cardiovascular diseases. The data are presented without the authors taking a position. This should allow the clinicians to make their own selection and individualize treatment, vii viii Preface based on a wide data base. Comparative data are presented only when specific comparative studies were performed. …

Taschenbuch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -Bernard ROY Professor, University of Paris-Dauphine Director of LAMSADE 11 is not unusual for a dozen or so loosely related working papers to be published in book form as the natural outgrowth of a scientific gathering. Although many a volu me of collected papers has come into point in this way, the homogeneity of the arti cles included will often be more apparent than real. As the reader will quickly ob serve, such is not the case with the present volume. As one can judge from its ti tle, 1t is in fact an outcome of an ed~torial project by J. Kacprzyk and M. Roubens. T~ey asked contributing authors to submit recent works which would examine. within a non-traditional theoretical framework, preference analysis and preference modeliing 1n a fuzzy context oriented towards decision aid. The articles by J.P. Ooignon, B. Monjardet, T. Tanino and Ph. Vincke empnasize the analysis of oreference structures, mainly in the presence of incomparability.

Taschenbuch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -Structural exchange rate modeling has proven extremely difficult during the recent post-1973 float. The disappointment climaxed with the papers of Meese and Rogoff (1983a, 1983b), who showed that a 'naive' random walk model distinctly dominated received theoretical models in terms of predictive performance for the major dollar spot rates. One purpose of this monograph is to seek the reasons for this failure by exploring the temporal behavior of seven major dollar exchange rates using nonstructural time-series methods. The Meese-Rogoff finding does not mean that exchange rates evolve as random walks; rather it simply means that the random walk is a better stochastic approximation than any of their other candidate models. In this monograph, we use optimal model specification techniques, including formal unit root tests which allow for trend, and find that all of the exchange rates studied do in fact evolve as random walks or random walks with drift (to a very close approximation). This result is consistent with efficient asset markets, and provides an explanation for the Meese-Rogoff results. Far more subtle forces are at work, however, which lead to interesting econometric problems and have implications for the measurement of exchange rate volatility and moment structure. It is shown that all exchange rates display substantial conditional heteroskedasticity. A particularly reasonable parameterization of this conditional heteroskedasticity, which captures the observed clustering of prediction error variances, is developed in Chapter 2. 160 pp. Englisch.…

Taschenbuch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -The purpose of this research monograph is to utilize algebraic and systems theory for the structure analysis and design of multivariable control systems described by state-space representations and matrix fraction descriptions. A unified approach characterizing the dynamics of a system through the formulation of the characteristic -matrix of the system is presented. The latent structures, solvents, divisors, and spectral factors of the non-singular characteristic -matrix and their relationships with the respesctive counterparts of the state-space representations are explored. Applications in model reduction, pole assignment design, modal control design for multivariable systems, parallel realizations and cascade realizations of multiport networks are illustrated. Computational algorithms and illustrative numerical examples are presented throughout the monograph. The reader is assumed to have a graduate level background in modern control theory. 220 pp. Englisch.…

Taschenbuch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -The volume contains the 23 papers selected for presentation at the ESOP '88 Conference, Nancy 1988. The theme of the ESOP conferences is the design, specification and implementation of programming languages and systems. Particular emphasis is placed on work in which an implemented system embodies an important concept or formal model of programming in such a way that its usefulness is demonstrated. Among the five sections of the volume, the one on language implementation contains the most papers. Here a rather wide spectrum of aspects, ranging from language implementation problems on parallel architectures and optimization of functional programs to new concepts for programming environments is covered. Another large section consists of papers in the area of algebraic specification and type concepts. The papers in this section are devoted to issues such as polymorphism, subtypes and notions of implementation and reuse for algebraic specifications. Two further sections are devoted to new language concepts and novel approaches to program development and verification. 392 pp. Englisch.…

Taschenbuch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -This book, the seventh in the series Exercises in Radiological Diagnosis, deals with sonography, an imaging procedure in which the ability of the radiologist plays an exceptionally important role. The author, Catherine Roy, has very extensive experience in the clinical use of sonography. She has selected the images, which are of excellent quality, with great care to illustrate a wide range of conditions and has supplemented them by commentaries and discussions which are easy to comprehend. The systematic use of schematic drawings to interpret the images makes it possible for the reader to follow the author's approach without any difficulty. Schematic drawings are par ticularly important in sonography because the relationship be tween the details in the images and the anatomy may be very weak. Images, schematic drawings, and text (both commentaries and interpretations) are three didactic elements which Cathe rine Roy has skill-fully combined in these exercises into an excellent whole. A.

Taschenbuch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -Pattern recognition is traditionally considered to cover all aspects of sensory data perception ranging from data acquisition, through preprocessing and low level analysis, to high level interpretation. Owing to its breadth and important application potential, the field of pattern recognition has been attracting considerable attention of researchers in academia and industry and consequently it has been witnessing a rapid growth and perpetual development. The need for dissemination of the latest results is being served by a host of international conferences on pattern recognition. One such series of meetings is regularly held in the United Kingdom under the auspices of the British Pattern Recognition Association. This volume contains papers presented at the BPRA 4th International Conference on Pattern Recognition held in Cambridge, March 28-30, 1988. Alongside the conventional topics of statistical and syntactic pattern recognition, contributions address issues in the hot subject areas of adaptive learning networks, computer vision, knowledge base methods and architectures for pattern processing, and among others, report progress in the application domains of document processing, speech and text recognition and shape analysis for industrial robotics. It is believed that the collection is not merely a report on current activities but that it will also be an important source of inspiration for future developments in the field of pattern recognition. 680 pp. Englisch.…

The issue of control emerges as a central theme. Control plays a keyrole, firstly, in organizing the victim's thoughts with regard to the batterer, and, secondly, in cases of repeated acts of violence over a length of time. The study shows acts of violence to be both 'impulsive' and 'instrumental' and thereby refutes competing explanations in the literature that violence is either 'impulsive' or 'instrumental.' 180 pp. Englisch.…

Taschenbuch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -stable isotope ratios act as naturally-occurring tracers for organic matter, making possible, under certain conditions, the quantification of coastal-offshore exchanges. In general, organic matter has isotope ratios characteristic of its origin (e. g. plants with different modes of photosynthesis and different growth conditions, anthropogenic compounds). These ratios are maintained as the organic matter moves through the biosphere and geosphere. A mixture of organic matter from two sources has isotope ratios intermediate between those of the two sources, in proportion to the fraction of material from each source. Isotope ratios are one of the few methods which can trace organic matter as it moves through natural ecosystems. Ratios can be measured on both the total organic matter and on particular chemical fractions or compounds. When used on organisms, isotope ratios provide information of organic matter actually assimilated into body tissues, not just material ingested. As with all tools, this method has certain limitations which must be borne in mind when interpreting its results. Firstly, specific environmental conditions must be met. This generally means an ecosystem with a limited and known number of sources of organic matter having different isotope ratios. Two sources with different isotope ratios are ideal; additional sources with other isotope ratios complicate interpretation. Secondly, the difference in isotope ratios of the two sources should be large compared with analytical variability. Thirdly, the ratios within each source should vary as little as possible. 384 pp. Englisch.…

Taschenbuch. Condizione: Neu. This item is printed on demand - Print on Demand Titel. Neuware -This book deals with central simple Lie algebras over arbitrary fields of characteristic zero. It aims to give constructions of the algebras and their finite-dimensional modules in terms that are rational with respect to the given ground field. All isotropic algebras with non-reduced relative root systems are treated, along with classical anisotropic algebras. The latter are treated by what seems to be a novel device, namely by studying certain modules for isotropic classical algebras in which they are embedded. In this development, symmetric powers of central simple associative algebras, along with generalized even Clifford algebras of involutorial algebras, play central roles. Considerable attention is given to exceptional algebras. The pace is that of a rather expansive research monograph. The reader who has at hand a standard introductory text on Lie algebras, such as Jacobson or Humphreys, should be in a position to understand the results. More technical matters arise in some of the detailed arguments. The book is intended for researchers and students of algebraic Lie theory, as well as for other researchers who are seeking explicit realizations of algebras or modules. It will probably be more useful as a resource to be dipped into, than as a text to be worked straight through.Springer-Verlag KG, Sachsenplatz 4-6, 1201 Wien 204 pp. Englisch.…

Neuware -The central topic of this research monograph is the relation between p-adic modular forms and p-adic Galois representations, and in particular the theory of deformations of Galois representations recently introduced by Mazur. The classical theory of modular forms is assumed known to the reader, but the p-adic theory is reviewed in detail, with ample intuitive and heuristic discussion, so that the book will serve as a convenient point of entry to research in that area. The results on the U operator and on Galois representations are new, and will be of interest even to the experts. A list of further problems in the field is included to guide the beginner in his research. The book will thus be of interest to number theorists who wish to learn about p-adic modular forms, leading them rapidly to interesting research, and also to the specialists in the subject.Springer-Verlag KG, Sachsenplatz 4-6, 1201 Wien 132 pp. Englisch.…
