Taschenbuch. Condizione: Neu. Neuware - One can observe that a wide range of human activities involves various forms of de sign. Especially if the goal implies the creation of an artifact, design is at the very center of these activities. It is the general understanding in the public to place design especially in the context of, for example, fashion, furniture, household items, cars, and architecture or in a more general way at the intersection of art and engineering. Of course, in the field of information technology, developers of software and hard ware are called system 'designers'. Design can be identified and considered in the context of many activities related to pUblishing: creating a product ad in a magazine, designing the layout of a newspaper, authoring a book. Summarizing these exam ples as 'creating documents', these are activities where two challenges with respect to design have to be met. Designing the content, its structure, and its relationship to the existing knowledge of potential readers is one, while the other refers to the 'rhetorical' aspects including designing the presentation of the material in order to communicate the content. Publishing is communicating knowledge.

Taschenbuch. Condizione: Neu. Neuware - The present book is based on lectures given by the author at the University of Tokyo during the past ten years. It is intended as a textbook to be studied by students on their own or to be used in a course on Functional Analysis, i. e. , the general theory of linear operators in function spaces together with salient features of its application to diverse fields of modern and classical analysis. Necessary prerequisites for the reading of this book are summarized, with or without proof, in Chapter 0 under titles: Set Theory, Topo logical Spaces, Measure Spaces and Linear Spaces. Then, starting with the chapter on Semi-norms, a general theory of Banach and Hilbert spaces is presented in connection with the theory of generalized functions of S. L. SOBOLEV and L. SCHWARTZ. While the book is primarily addressed to graduate students, it is hoped it might prove useful to research mathe maticians, both pure and applied. The reader may pass, e. g. , from Chapter IX (Analytical Theory of Semi-groups) directly to Chapter XIII (Ergodic Theory and Diffusion Theory) and to Chapter XIV (Integration of the Equation of Evolution). Such materials as 'Weak Topologies and Duality in Locally Convex Spaces' and 'Nuclear Spaces' are presented in the form of the appendices to Chapter V and Chapter X, respectively. These might be skipped for the first reading by those who are interested rather in the application of linear operators.

Buch. Condizione: Neu. Neuware - In Alcohol and Hormones, leading researchers concisely review what is known about each human hormone system and how these systems are affected by alcohol use, to a lesser extent, other drugs of abuse. The contributors show clearly just how the body is regulated and how its normal functioning can be changed by alcohol.Major topics covered range from alcohol-stress interactions and the effects of alcohol on vitamin A metabolism (fetal alcohol syndrome and neural tube development) to how alcohol blocks the release of various peptide hormones, to its effects on puberty-related events in the female. There are also articles about how alcohol affects the control of body temperature, the impact of alcohol on male sexual development during puberty, the role of TRH in alcohol use disorders, and the possibility for a neuroendocrinological component in alcoholism.Alcohol and Hormones will be of interest to biomedical and alcohol researchers, neurobiologists, endocrinologists, pharmacologists, psychiatrists, and some clinicians interested in a deeper understanding of the effects of alcohol on the body.

Buch. Condizione: Neu. Neuware - It is recognized that formal design and verification methods are an important requirement for the attainment of high quality system designs. The field has evolved enormously during the last few years, resulting in the fact that formal design and verification methods are nowadays supported by several tools, both commercial and academic. If different tools and users are to generate and read the same language then it is necessary that the same semantics is assigned by them to all constructs and elements of the language. The current IEEE standard VHDL language reference manual (LRM) tries to define VHDL as well as possible in a descriptive way, explaining the semantics in English. But rigor and clarity are very hard to maintain in a semantics defined in this way, and that has already given rise to many misconceptions and contradictory interpretations. Formal Semantics for VHDL is the first book that puts forward a cohesive set of semantics for the VHDL language. The chapters describe several semantics each based on a different underlying formalism: two of them use Petri nets as target language, and two of them higher order logic. Two use functional concepts, and finally another uses the concept of evolving algebras. Formal Semantics for VHDL is essential reading for researchers in formal methods and can be used as a text for an advanced course on the subject.

Buch. Condizione: Neu. Neuware - This volume brings together a sample of the best of the studies that illustrate two recent trends in research on deviant behavior. The first of these trends is the investigation of deviant behavior in longitudinal perspective. Panels of subjects are followed over long periods of time to establish temporal relationships be tween deviant behavior and the antecedents and consequences of deviant behav ior. The second trend in contemporary research on deviance is the recognition of the association among forms of deviant behavior such as violence, drug abuse, and theft. The recognition of the covariation among forms of deviance stimulated questions regarding the nature of the relationships among multiple forms of de viance. Is one form of deviant behavior a cause or a consequence of other forms of deviant behavior What variables mediate and moderate such causal relation ships Do different forms of deviant behavior have common antecedents and consequences Independent of the foregoing relationships, do particular forms of deviant behavior have unique antecedents and consequences The eight original research studies that, along with the introduction and overview, constitute this volume are based on data drawn from among the most influential longitudinal studies in the general area of deviant behavior. These studies variously consider common and pattern-specific antecedents and conse quences, reciprocal influences, and intervening and moderating variables in causal relationships among drug use, crime, and other forms of deviance.

Buch. Condizione: Neu. Neuware - Many industrialized countries are facing large problems with their public pension systems in the 21st century. An unfavourable age distribution, with lower population shares in working ages and increasing shares and numbers of elderly persons in the future will lead, under current pension systems, to a drop in contributions and at the same time to sharply rising amounts of benefits paid. This book analyzes the impact of dynamics in age structure and marital status composition on future public pension expenditures in twelve industrialized countries. It shows that there is no demographic response to population ageing at the horizon 2030. Neither an increase in fertility nor an inflow of migrants can rejuvenate national populations, unless fertility and/or migration reach unrealistically high levels. Therefore, the overall conclusion of this book is that demographic variables are of limited help to relieve the burden of future public pension expenditures. Substantial reductions of the public pension burden have to be sought in socioeconomic measures, and not in adjusting demographic conditions. The book includes various demographic and pension scenarios for pension costs in the coming decades for Austria, Canada, the Czech and Slovak Republics, Finland, France, Germany, Hungary, Italy, the Netherlands, Norway, Poland, and Sweden. Not only old age pensions, but also disability and survivor pensions have been investigated. Variant projections were calculated for changes in demographic, labour force, and pension system variables. In addition, separate case studies for three countries deal with: a pension system in Austria in which benefits depend on the number children ever born; the impact of household dynamics on social security in the Netherlands, not just marriage and marriage dissolution; and with the consequences of economic growth for public pensions in Sweden.

Buch. Condizione: Neu. Neuware - Recent advances in surgical procedures for the management of focal liver diseases have greatly increased the demand for diagnostic accuracy. So far these demands have been only partially met by further technical developments such as colour coded duplex sonography, spiral CT and marked improvements in magnetic resonance imaging. It is becoming increasingly clear that liver specific contrast media are essential for utilizing these technical developments to their fullest advantage in patient care. Against this background, a workshop was held to explore the current methods of diagnostic imaging of the liver and to try and establish a profile for the future liver specific contrast media. The pathologist's introductory and general overview is followed by chapters on the individual imaging procedures such as ultrasound, CT and MRI, so that each of the three is given the attention it deserves. The book will be of interest to radiologists from the various disciplines, and also those who plan and perform therapies, particularly surgeons and internists.

Buch. Condizione: Neu. Neuware - In the past nuclear medicine has tended to develop in cycles governed by the development of new radiopharmaceuticals followed or preceded by advances in instrumentation. The development of alternative techniques, such as X-Ray Computer Tomography, NMR Imaging and Ultrasound have also had a stimulating effect and pointed the way to new developments. The development of Positron Emission Tomography, while in itself of limited application because of high costs involved, provided a great deal of information which led to the development of new organ or disease specific, single photon emitting radiopharmaceuticals together with tomographic Gamma cameras, whereby detailed information on the biodistribution of the reagents could be obtained with accurate spatial resolution presented in a form suitable for comparison with the other imaging modalities. This technology, known as Single Photon Emission (Computer) Tomography (SPECT or SPET, as the mood takes you) is now an essential tool in nuclear medicine. The volume presents a basic guideline to the technology involved and discusses the application of the method to the investigation of various anatomical regions of the body. The book is an aide mémoire to the routine practitioner and a source of information for other medical specialists.

Buch. Condizione: Neu. Neuware - The development of photosensitive materials in general and photoreactive polymers in particular is responsible for major advances in the information, imaging, and electronic industries. Computer parts manufacturing, information storage, and book and magazine publishing all depend on photoreactive polymer systems. The photo-and radiation-induced processes in polymers are also active areas of research. New information on the preparation and properties of com mercially available photosensitive systems is constantly being acquired. The recent demand for environmentally safe solvent-free and water-soluble materials also motivated changes in the composition of photopolymers and photoresists. The interest in holographic recording media for head-up displays, light scanners, and data recording stimulated development of reconfigurable and visible light sensitive materials. Photoconductive polymerizable coatings are being tested in electrostatic proofing and color printing. The list of available initiators, poly meric binders, and other coating ingredients is continually evolving to respond to the requirements of low component loss (low diffusivity) and the high rate of photochemical reactions.

Buch. Condizione: Neu. Neuware - The Office of Health and Environmental Research (OHER) has supported and continues to support development of computational approaches in biology and medicine. OHER's Radiological and Chemical Physics Program initiated development of computational approaches to determine the effects produced by radiation of different quality (such as high energy electrons, protons, helium and other heavy ions, etc. ) in a variety of materials of biological interest-such as water, polymers and DNA; these include molecular excitations and sub-excitations and the production of ionization and their spatial and temporal distribution. In the past several years, significant advances have been made in computational methods for this purpose. In particular, codes based on Monte Carlo techniques have been developed that provide a realistic description of track-structure produced by charged particles. In addition, the codes have become sufficiently sophisticated so that it is now possible to calculate the spatial and temporal distribution of energy deposition patterns in small volumes of subnanometer and nanometer dimensions. These dimensions or resolution levels are relevant for our understanding of mechanisms at the molecular level by which radiations affect biological systems. Since the Monte Carlo track structure codes for use in radiation chemistry and radiation biology are still in the developmental stage, a number of investigators have been exploring different strategies for improving these codes.

Buch. Condizione: Neu. Neuware - Deryn Watson and David Tinsley The topic of the conference, integrating infonnation technology into education, is both broad and multi-facetted. In order to help focus the papers and discussion we identified 7 themes: - Current developments in society and education influencing integration; - Teachers, their roles and concerns; - Learners, their expectations of and behaviour in an integrated environment; - Developments and concerns in the curriculum; - Successes and failures in existing practice; - Organisation and management of integrated environments; - Identification of social and political influences. Each author was invited to focus on one theme, and these remained strands throughout as can be seen from the short papers and focus group reports. The first and most significant concern therefore was to be clear about our notions of integration; what do we mean and how is this relevant Our keynote paper from Cornu clearly marked out this debate by examining the notion of integration and alerting us to the fact that as long as the use of IT is still added to the curriculum, then integration has not yet begun.

Buch. Condizione: Neu. Neuware - Chronic inflammatory bowel disease still represents a major gastroenterological challenge, in view of the unclear aetiology and unsatisfactory therapy. This book, the proceedings of a Falk Symposium held in Lübeck, Germany on 4--5 March 1994, will act as a vehicle for our current knowledge, and promote the dialogue between clinicians and those involved with the associated sciences. The book begins with international experts discussing the more recent theories concerning the aetiology and pathogenesis. Later on, the discussion turns to questions of diagnosis, and the conservative and surgical treatment of Crohn's disease and ulcerative colitis are dealt with in detail. This volume in the Falk Symposium both represents a forum of experts for discussion of the most recent findings, and provides clinical gastroenterologists with an opportunity to inform themselves of the state of the art in the field of inflammatory bowel disease.

Buch. Condizione: Neu. Kibiuk, L.V. (illustratore). Neuware - The problems of the patellofemoral joint remain a challenge to the orthopaedic surgeon. In spite of many articles in scientific journals, an outstanding monograph, and several excellent textbook chapters, the patella is still an enigma in many respects. The etiology of patellar pain is controversial, and there is no completely satisfying explanation for its cause or its relationship to chondromalacia. Curiously, neither the widespread use of arthroscopy nor the advent of newer diagnostic tests such as CT scanning and magnetic resonance imaging have cast much light. Without a better understanding of why patellar disorders occur it is not surprising that there is no consensus on how to fix them. Arthros copy has contributed little except to the patient's psyche. The currently most popular surgical treatment for recurrent dislocation of the patella was first described 50 years ago. One concrete advance, albeit a small one, is a better understanding of the role of anatomical abnormalities and patellofemoral dysplasia in patellar instabilities. It gives me great pleasure that many of the contributors are, like Dr.

Buch. Condizione: Neu. Neuware - This volume of papers grew outof a research project on 'Cross-Linguistic Quantification' originated by Emmon Bach, Angelika Kratzer and Barbara Partee in 1987 at the University of Massachusetts at Amherst, and supported by National Science Foundation Grant BNS 871999. The publication also reflects directly or indirectly several other related activ ities. Bach, Kratzer, and Partee organized a two-evening symposium on cross-linguistic quantification at the 1988 Annual Meeting of the Linguistic Society of America in New Orleans (held without financial support) in order to bring the project to the attention of the linguistic community and solicit ideas and feedback from colleagues who might share our concern for developing a broader typological basis for research in semantics and a better integration of descriptive and theoretical work in the area of quantification in particular. The same trio organized a six-week workshop and open lecture series and related one-day confer ence on the same topic at the 1989 LSA Linguistic Institute at the University of Arizona in Tucson, supported by a supplementary grant, NSF grant BNS-8811250, and Partee offered a seminar on the same topic as part of the Institute course offerings. Eloise Jelinek, who served as a consultant on the principal grant and was a participant in the LSA symposium and the Arizona workshops, joined the group of editors for this volume in 1989.

Buch. Condizione: Neu. Neuware - Advances in information technology provide opportunities for the development of computer systems that support risk managers in complex tasks.

Buch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -The Seven Countries Study has made central contributions to the under standing of the socio-cultural influences on population rates of cardiovascular diseases (CVD). It has pointed the way to preventive strategies for whole populations. The Study is unique as a long-term investigation, now in its 35th year. This pioneering work arose in part from a meeting between Professors Ancel Keys and Noboru Kimura to discuss differences observed in clinical mani festations and pathology of coronary disease in the U.S. and Japan. Professor Keys started explorations of the importance in these differences of dietary fat and serum cholesterol when he visited Japan in 1954, and thereafter initiated the Seven Countries Study to test these hypotheses. In the Japanese cohorts of the Study, it became evident from the outset that coronary artery disease was extremely rare, but its incidence has since increased along with dramatic lifestyle changes from traditional Japanese to western styles. The Japanese experience contrasts with a reduction in coronary artery disease in many western countries along with establishment of major preventive efforts in risk factor reduction and cardiac care. 256 pp. Englisch.

Taschenbuch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -Each year there are improvements in safety-critical system technology. These arise both from developments in the contributing technologies, such as safety engineering, software engineering, human factors and risk assessment, and from the adoption or adaptation of appropriate techniques from other domains, such as security. For these improvements to be of real benefit, they need to be applied during the appropriate stage in the life cycle of the system, whether it be development, assessment, or operation. For this to occur, they must be communicated and explained. Each year the Safety-critical Systems Symposium offers a distinguished forum for the presentation of papers on such developments, and also for papers from industry on the lessons learned from the use of technologies and methods. The results of many collaborative research projects, with components from both industry and academia, are reported in a universally understandable form. In 1995 the Symposium was held in Brighton, a venue calculated to stimulate not just the presenters of papers, but all the delegates. Yet, this book of Proceedings is intended not only for the delegates but also for readers not able to attend the event itself. We welcome both categories of reader. Delegates have the benefit of attending the presentations and the opportunity to participate in the discussions; those who take up this book after the event can peruse it attheir leisure and, perhaps, on account of it will resolve to attend subsequent symposia. 340 pp. Englisch.
