Buch. Condizione: Neu. Neuware - Coupled with the general decline in real estate values and opportunitie~ for capital fonnation, the health care industry is in the midst of unprecedented change that has resulted in unneeded real estate, excess debt and a major need for capital to meet new organizational challenges. Indeed, these are challenging times, evolutionary if not revolutionary: Reorganizations. Restructures. Shakeouts. Closures. Do you know what the strategic alternatives and solutions are for your facility or organization Has your 1980s health care asset become a 1990s liability What will your organization look like in the post-health care refonn era, and how will your real estate help --or hinder --this transition If the private payor doesn't get you, the government may. If the government doesn't get you, the market will. Only the strong, the swift and the knowledgeable will survive these 'winds of change' and the various forces at play today. Will your organization be one of those which do If you are unsure of the answers to these questions, this publication may be for you. Based upon the inaugural University of Southern CalifornialManatt Phelps Phillips Health Care Industry Real Estate Institute, held in Los Angeles, California on February 9, 1995, if this book does not provide all of the answers, it will provide some, as well as assisting the reader at least to identify the questions that need asking, and answering.

Buch. Condizione: Neu. Neuware - Suppose that a congenitally blind person has learned to distinguish and name a sphere and a cube by touch alone. Then imagine that this person suddenly recovers the faculty of sight. Will he be able to distinguish both objects by sight and to say which is the sphere and which the cube This was the question which the Irish politician and scientist William Molyneux posed in 1688 to John Locke. Molyneux's question has intrigued a wide variety of intellectuals for three centuries. Those who have attempted to solve it include Berkeley, Reid, Leibniz, Voltaire, La Mettrie, Condillac, Diderot, Müller, Helmholtz, William James and Gareth Evans. This book is the first comprehensive survey of the history of the discussion about Molyneux's problem. It will be of interest to historians of both philosophy and psychology.

Box 11650, 2502 AR The Hague, The Netherlands \*\* CBGS, Markiesstraat 1, 1000 Brussels, Belgium The series 'Population and Family in the Low Countries' (POPFAM), established in 1976, aims to introduce selected issues of demographic research in Flanders/Belgium and the Netherlands to an international audience. The publication series results from cooperation between the Nether lands Interdisciplinary Demographic Institute (NIDI, The Hague) and the Flemish Population and Family Study Centre (CBGS, Brussels). This 1995 edition is the 111h in the series. In 1995, the NIDI celebrates its 25th anniversary as the Dutch national demographic institute, making it a special year for Dutch demography. The contents of this publication obviously highlights this event as most articles selected for this edition are written by Dutch or NIDI related scholars. The article 'Ageing and the demand for care: scenario studies for Europe' by Hanna van Solinge and Jenny de Jong Gierveld concerns a comparative study with respect to the consequences of ageing populations for the infrastructure of care for the elderly. It presents results of a scenario study on future developments in demand and supply of elderly care services for a selected number of European countries, summarizing an extensive study on the impact of ageing populations on the socio-medical system conducted by the authors on behalf of the European Population Committee of the Council of Europe.

Buch. Condizione: Neu. Neuware - Rethinking Hypermedia: The Microcosm Approach is essentially the story of the Microcosm hypermedia research and development project that started in the late 1980's and from which has emerged a philosophy that re-examines the whole concept of hypermedia and its role in the evolution of multimedia information systems. The book presents the complete story of Microcosm to date. It sets the development of Microcosm in the context of the history of the subject from which it evolved, as well as the developments in the wider world of technology over the last two decades including personal computing, high-speed communications, and the growth of the Internet. These all lead us towards a world of global integrated information environments: the publishing revolution of the 20th century, in principle making vast amounts of information available to anybody anywhere in the world. Rethinking Hypermedia: The Microcosm Approach explains the role that open hypermedia systems and link services will play in the integrated information environments of the future. It considers issues such as authoring, legacy systems and data integrity issues, and looks beyond the simple hypertext model provided in the World Wide Web and other systems today to the world of intelligent information processing agents that will help us deal with the problems of information overload and maintenance. Rethinking Hypermedia: The Microcosm Approach will be of interest to all those who are involved in designing, implementing and maintaining hypermedia systems such as the World Wide Web by setting the groundwork for producing a system that is both easy to use and easy to maintain. Rethinking Hypermedia: The Microcosm Approach is essential reading for anyone involved in the provision of online information.

Buch. Condizione: Neu. Neuware - During the last decade or so vaccine development has been facilitated by rapid advances in molecular and cell biology. These have laid the foundations of a new generation of vaccines exemplified by subunit vaccines produced through gene cloning and by synthetic peptides mimicking small regions of proteins on the outer coat of viruses. Such peptide~ are capable of eliciting virus-neutralizing antibodies. Unfortunately, subunit and peptide vaccines are only weakly or non immunogenic in the absence of immunological adjuvants that are known to augment specific cell-mediated immune responses to the antigens and to promote the formation of protective antibodies. This book contains the proceedings of the 4th NATO Advanced Studies Institute (ASI) 'Vaccines: New Generation Immunological Adjuvants' held at Cape Sounion Beach, Greece, during 24 June -5 . July 1994 and deals in depth with both theoretical and practical aspects of vaccinology. These include the role of antigen presenting cells in the induction of immune responses. immunopotentiation by a variety of new generation immunological adjuvants and vaccine carriers. and recent advances and perspectives in experimental vaccines as well as vaccinatioll with nucleic acids. We express our appreciation to Dr. K. Dalsgaard and Dr. J. L. Virelizier for their cooperatioll in planning the ASI and to Mrs. Concha Pening for her excellent production of the manuscripts. The ASI was held under the sponsorship of NATO Scientific Affairs Division and generously co-sponsored by SmithKline Beecham Pharmaceuticals (Philadelphia).

Buch. Condizione: Neu. Neuware - This volume presents five pedagogical articles spanning frontier developments in contemporary nuclear physics ranging from the physics of a single nucleon to nucleosynthesis in the Big Bang. Although the objectives of Advances in Nuclear Physics have been and will continue to be quite distinct from those of conventional conference proceedings, the articles in this volume are carefully edited and expanded manuscripts based on an outstanding series of lectures delivered at the VI J. A. Swieca Summer School in Brazil. Starting at the smallest scale, the first article by Dan Olof Riska addresses realistic chiral symmetric models of the nucleon. Since the analytic tools are not yet developed to solve nonperturbative QCD directly, significant effort has been devoted in recent years to the development of models which incorporate and are constrained by the approximate chiral symmetry manifested in QCD. This article provides a clear introduction to chiral symmetry and the Skyrme model, and discusses the Skyrme model's relation to the chiral bag model, its extensions, and its application to nucleons and hyperons.

Buch. Condizione: Neu. Neuware - Developing correct and efficient software is far more complex for parallel and distributed systems than it is for sequential processors. Some of the reasons for this added complexity are: the lack of a universally acceptable parallel and distributed programming paradigm, the criticality of achieving high performance, and the difficulty of writing correct parallel and distributed programs. These factors collectively influence the current status of parallel and distributed software development tools efforts. Tools and Environments for Parallel and Distributed Systems addresses the above issues by describing working tools and environments, and gives a solid overview of some of the fundamental research being done worldwide. Topics covered in this collection are: mainstream program development tools, performance prediction tools and studies; debugging tools and research; and nontraditional tools. Audience: Suitable as a secondary text for graduate level courses in software engineering and parallel and distributed systems, and as a reference for researchers and practitioners in industry.

Buch. Condizione: Neu. Neuware - Forrester discusses animal rights, obligations concerning future generations, abortion, limiting medical treatment, and euthanasia. Persons are defined as individuals who ought to be treated in accordance with all sound moral principles. The author develops an account of what moral principles are sound, how we can apply them to complex situations, and what makes it reasonable to treat individuals in accordance with particular moral principles. This discussion puts the book's practical conclusions on a sounder basis than much other work on practical ethics. Most such authors state some general principles, but say little about why these principles should be accepted. Moreover, they rarely show how general principles can generate answers to specific dilemmas. Some even maintain that general principles are irrelevant. Since Forrester is both a nurse practitioner and a philosopher, she has had direct acquaintance with many agonizing situations in medicine. Summaries of the theoretical conclusions are included to enable nonprofessionals to follow the discussion of practical issues. The book will thus interest not only professional philosophers, but also non-philosophers concerned with problems in medical and environmental ethics, abortion, and animal rights.

Buch. Condizione: Neu. Neuware - Multimedia computing has emerged in the last few years as a major area of research. Multimedia computer systems have opened a wide range of applications by combining a variety of information sources, such as voice, graphics, animation, images, audio and full-motion video. Looking at the big picture, multimedia can be viewed as the merging of three industries: computer, communications, and broadcasting industries. Research and development efforts can be divided into two areas. As the first area of research, much effort has been centered on the stand-alone multimedia workstation and associated software systems and tools, such as music composition, computer-aided education and training, and interactive video. However, the combination of multimedia computing with distributed systems offers even greater potential. New applications based on distributed multimedia systems include multimedia information systems, collaborative and video conferencing systems, on-demand multimedia services, and distance learning. Multimedia Systems and Techniques is one of two volumes published by Kluwer, both of which provide a broad introduction into this fast moving area. The book covers fundamental concepts and techniques used in multimedia systems. The topics include multimedia objects and related models, multimedia compression techniques and standards, multimedia interfaces, multimedia storage techniques, multimedia communication and networking, multimedia synchronization techniques, multimedia information systems, scheduling in multimedia systems, and video indexing and retrieval techniques. Multimedia Systems and Techniques, together with its companion volume, Multimedia Tools and Applications, is intended for anyone involved in multimedia system design and applications and can be used as a textbook for advanced courses on multimedia.

Buch. Condizione: Neu. Neuware - Living and Dying Well takes an informed, interdisciplinary approach to the problems, data, theory, and procedures that a just society must consider when establishing policies regarding human life and death. Leading psychologist Lewis Petrinovich expands on the controversial arguments developed in his earlier work, Human Evolution, Reproduction, and Morality, and considers such contemporary issues as: the morality of human genetic screening and of the Human Genome Project; organ transplants; the allowance of suicide and euthanasia; and physicians assisting in the dying process.

Buch. Condizione: Neu. Neuware - The field of food colloids is concerned with the physical chemistry of food systems viewed as assemblies of particles and macromolecules in various states of supramolecular and microscopic organization. The objective is to relate the equilibrium and dynamic properties of the system to the inter actions amongst the constituent molecular and particulate entities. The emphasis is on structure and kinetics at the colloidal scale, and with the distribution of molecular food components (proteins, lipids, poly saccharides, etc.) between dispersed and continuous bulk phases (water, fat, air, etc.) and various kinds of interfaces (oil-water, air-water, etc.). Food products such as butter, cheese, ice-cream, margarine, mayonnaise of food colloids. and yoghurt are all examples This book describes some recent experimental and theoretical develop ments in the field of food colloids. By way of background, we start with a brief survey of the current consumer trends which may point the way towards future research opportunities in the field. Chapter 1 also attempts to illustrate the way in which advances in instrumental methods and experimental investigations of well-defined mixed protein-surfactant systems are offering new insights into the structure of protein adsorbed layers and the competitive adsorption of proteins in oil-in-water emulsion systems.

Buch. Condizione: Neu. Neuware - Designing is one of the most significant of human acts. Surprisingly, given that designing has been occurring for many millenia, our understanding of the processes of designing is remarkably limited. Recently, design methods have been formalised not as humano-centred processes but as processes capable of computer implementation with the goal of augmenting human designers. This volume contains contributions which cover design methods based on evolutionary systems, generative processes, evaluation methods and analysis methods. It presents the state of the art in formal design methods for computer aided design.

Buch. Condizione: Neu. Neuware - Client/Server applications are of increasing importance in industry, and have been improved by advanced distributed object-oriented techniques, dedicated tool support and both multimedia and mobile computing extensions. Recent responses to this trend are standardized distributed platforms and models including the Distributed Computing Environment (DCE) of the Open Software Foundation (OS F), Open Distributed Processing (ODP), and the Common Object Request Broker Architecture (CORBA) of the Object Management Group (OMG). These proceedings are the compilation of papers from the technical stream of the IFIPIIEEE International Conference on Distributed Platforms, Dresden, Germany. This conference has been sponsored by IFIP TC6.1, by the IEEE Communications Society, and by the German Association of Computer Science (GI -Gesellschaft fur Informatik). ICDP'96 was organized jointly by Dresden University of Technology and Aachen University of Technology. It is closely related to the International Workshop on OSF DCE in Karlsruhe, 1993, and to the IFIP International Conference on Open Distributed Processing. ICDP has been designed to bring together researchers and practitioners who are studying and developing new methodologies, tools and technologies for advanced client/server environ ments, distributed systems, and network applications based on distributed platforms.

Buch. Condizione: Neu. Neuware - Optimization problems abound in most fields of science, engineering, and tech nology. In many of these problems it is necessary to compute the global optimum (or a good approximation) of a multivariable function. The variables that define the function to be optimized can be continuous and/or discrete and, in addition, many times satisfy certain constraints. Global optimization problems belong to the complexity class of NP-hard prob lems. Such problems are very difficult to solve. Traditional descent optimization algorithms based on local information are not adequate for solving these problems. In most cases of practical interest the number of local optima increases, on the aver age, exponentially with the size of the problem (number of variables). Furthermore, most of the traditional approaches fail to escape from a local optimum in order to continue the search for the global solution. Global optimization has received a lot of attention in the past ten years, due to the success of new algorithms for solving large classes of problems from diverse areas such as engineering design and control, computational chemistry and biology, structural optimization, computer science, operations research, and economics. This book contains refereed invited papers presented at the conference on 'State of the Art in Global Optimization: Computational Methods and Applications' held at Princeton University, April 28-30, 1995. The conference presented current re search on global optimization and related applications in science and engineering. The papers included in this book cover a wide spectrum of approaches for solving global optimization problems and applications.

Buch. Condizione: Neu. Neuware - A Festschrift in honor of Professor Marvin L. Cohen This volume is a Festschrift in honor of Professor Marvin L. Cohen. The articles, contributed by leading researchers in condensed matter physics, high-light recent advances in the use of quantum theory to explain and predict properties of real materials. The invention of quantum mechanics in the 1920's provided detailed descriptions of the electronic structure of atoms. However, a similar understanding of solids has been achieved only in the past 30 years, owing to the complex electron-ion and electron electron interactions in these systems. Professor Cohen is a central figure in this achievement. His development of the pseudopotential and total energy methods provided an alternate route using computers for the exploration of solids and new materials even when they have not yet been synthesized. Professor Cohen's contributions to materials theory have been both fundamental and encompassing. The corpus of his work consists of over 500 papers and a textbook. His band structures for semiconductors are used worldwide by researchers in solid state physics and chemistry and by device engineers. Professor Cohen's own use of his theories has resulted in the determination of the electronic structure, optical properties, structural and vibrational properties, and superconducting properties of numerous condensed matter systems including semiconductors, metals, surfaces, interfaces, defects in solids, clusters, and novel materials such as the fullerides and nanotubes.

Buch. Condizione: Neu. Neuware - This book documents the proceedings of the symposium, 'Mineral Scale Formation and Inhibition,' held at the American Chemical Society Annual Meeting August 21 to 26, 1994, in Washington, D. C. The symposium, sponsored by the Division of Colloid and Surface Chemistry, was held in honor of Professor George H. Nancollas for his pioneering work in the field of crystal growth from solution. A total of 30 papers were presented by a wide spectrum of scientists. This book also includes papers that were not presented but were in the symposium program. The separation of a solid by crystallization is one of the oldest and perhaps the most frequently used operations in chemistry. Because of its widespread applicability, in recent years there has been considerable interest exhibited by academic and industrial scientists in understanding the mechanisms of crystallization of sparingly soluble salts. The salt systems of great interest in industrial water treatment area (i. e. , cooling and boiler) include carbon ates, sulfates, phosphates, and phosphonates of alkaline earth metals. Although not as common as calcium carbonate and calcium sulfate, barium and strontium sulfates have long plagued oil field and gas production operations. The build-up of these sparingly soluble salts on equipment surfaces results in lower heat transfer efficiency, increased corrosion rates, increased pumping costs, etc. In the laundry application, insoluble calcium carbonate tends to accumulate on washed fabrics and washing equipment parts, resulting in undesirable fabric-encrustation or scaling.

Taschenbuch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -The notes in this volume were written as a part of a Nachdiplom course that I gave at the ETH in the summer semester of 1995. The aim of my lectures was the development of some of the basics of the interaction of homological algebra, or more specifically the cohomology of groups, and modular representation theory. Every time that I had given such a course in the past fifteen years, the choice of the material and the order of presentation of the results have followed more or less the same basic pattern. Such a course began with the fundamentals of group cohomology, and then investigated the structure of cohomology rings, and their maximal ideal spectra. Then the variety of a module was defined and related to actual module structure through the rank variety. Applications followed. The standard approach was used in my University of Essen Lecture Notes [e1] in 1984. Evens [E] and Benson [B2] have written it up in much clearer detail and included it as part of their books on the subject. 92 pp. Englisch.

Taschenbuch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -Mathematics is a beautiful subject, and entire functions is its most beautiful branch. Every aspect of mathematics enters into it, from analysis, algebra, and geometry all the way to differential equations and logic. For example, my favorite theorem in all of mathematics is a theorem of R. NevanJinna that two functions, meromorphic in the whole complex plane, that share five values must be identical. For real functions, there is nothing that even remotely corresponds to this. This book is an introduction to the theory of entire and meromorphic functions, with a heavy emphasis on Nevanlinna theory, otherwise known as value-distribution theory. Things included here that occur in no other book (that we are aware of) are the Fourier series method for entire and mero morphic functions, a study of integer valued entire functions, the Malliavin Rubel extension of Carlson's Theorem (the 'sampling theorem'), and the first-order theory of the ring of all entire functions, and a final chapter on Tarski's 'High School Algebra Problem,' a topic from mathematical logic that connects with entire functions. This book grew out of a set of classroom notes for a course given at the University of Illinois in 1963, but they have been much changed, corrected, expanded, and updated, partially for a similar course at the same place in 1993. My thanks to the many students who prepared notes and have given corrections and comments. 200 pp. Englisch.

Taschenbuch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -In this volume are collected notes of lectures delivered at the First In ternational Research Institute of the Mathematical Society of Japan. This conference, held at Tohoku University in July 1993, was devoted to geometry and global analysis. Subsequent to the conference, in answer to popular de mand from the participants, it was decided to publish the notes of the survey lectures. Written by the lecturers themselves, all experts in their respective fields, these notes are here presented in a single volume. It is hoped that they will provide a vivid account of the current research, from the introduc tory level up to and including the most recent results, and will indicate the direction to be taken by future researeh. This compilation begins with Jean-Pierre Bourguignon's notes entitled 'An Introduction to Geometric Variational Problems,' illustrating the gen eral framework of the field with many examples and providing the reader with a broad view of the current research. Following this, Kenji Fukaya's notes on 'Geometry of Gauge Fields' are concerned with gauge theory and its applications to low-dimensional topology, without delving too deeply into technical detail. Special emphasis is placed on explaining the ideas of infi nite dimensional geometry that, in the literature, are often hidden behind rigorous formulations or technical arguments. 164 pp. Englisch.

This item is printed on demand - it takes 3-4 days longer - Neuware -This is a histological classification of tumours and tumour-like lesions of the exocrine pancreas which also includes those tu mours showing a mixture of exocrine and endocrine elements. The classification is based principally on standard microscopic observations, but whenever indicated it incorporates diagnosti cally valuable immunohistological findings. In addition, the most important immunohistological findings which are helpful in cat egorizing pancreatic tumours are summarised in Table 1. The major guideline of this classification scheme is the group ing of the pancreatic exocrine tumours according to their biologi cal behaviour. Thus, the neoplasms are broadly divided into benign (adenoma) and malignant tumours (carcinoma). How ever, in recent years we have learned that this division is not a sharp but rather a gradual transition. We therefore added a third group which we call 'tumours of uncertain malignant potential' representing a borderline category analogous to that recognized for some ovarian tumours. This group includes mucinous cystic tumour, intraductal papillary-mucinous tumour and solid pseudopapillary tumour. These neoplasms are defined by the grade of dysplasia and/or potential to become malignant. Mucinous cystic tumours of uncertain malignant potential, for instance, exhibit moderate epithelial dysplasia, but do not show severe dysplasia/carcinoma in situ changes, nor carcinomatous invasion of the cyst wall or the adjacent pancreatic tissue. Solid pseudopapillary tumour has a benign looking histological ap pearance, but metastases may occur. Biologically, all these neoplasms are primarily slow-growing lesions and have an excel lent prognosis when adequately treated by complete resection. 84 pp. Englisch.

This item is printed on demand - it takes 3-4 days longer - Neuware -Man's understanding of how this planet is put together and how it evolved has changed radically during the last 30 years. This great revolution in geology - now usually subsumed under the concept of Plate Tectonics - brought the realization that convection within the Earth is responsible for the origin of today's ocean basins and conti nents, and that the grand features of the Earth's surface are the product of ongoing large-scale horizontal motions. Some of these notions were put forward earlier in this century (by A. Wegener, in 1912, and by A. Holmes, in 1929), but most of the new ideas were an outgrowth of the study of the ocean floor after World War II. In its impact on the earth sciences, the plate tectonics revolution is comparable to the upheaval wrought by the ideas of Charles Darwin (1809-1882), which started the intense discussion on the evolution of the biosphere that has recently heated up again. Darwin drew his inspiration from observations on island life made during the voyage of the Beagle (1831-1836), and his work gave strong impetus to the first global oceanographic expedition, the voyage of HMS Challenger (1872- 1876). Ever since, oceanographic research has been intimately associ ated with fundamental advances in the knowledge of Earth. This should come as no surprise. After all, our planet's surface is mostly ocean. 376 pp. Englisch.

Facts: A leisure term with an unbounded value function, when added to utility in the Lucas (1988) 'mechanics of economic development', expands enormously the range of data covered by the theory. To explain this we have to ask two questions. First: why leisure would be so much desired Perhaps because leisure is one's own time and such a leisure term means an unbounded value of individual freedom. But why leisure is economically productive, as implied by the results obtained in this study Perhaps because cognitive innovations often occur during the time which in economics is registered as leisure Then an unbounded leisure term would also make room for an unbounded creation of knowledge, as distinguished from the mere transmission of knowledge in education and training. In any case the leisure term seems to act as if it where the'hole' through which strong nonmaterial values affect economics. The ensuing 'extended mechanics' is derived in Chapters 4-6 and proves to involve an extension of growth theory as well as a theory of the causal part of business cycles. Their empirical verification is given by showing (i) that the existence of the two Basic Growth Paths derived from this theory, defining its Growth Type 1 and Growth Type 2, respectively, is verified already by the statistics collected by Solow (1957) but ignored so far (see Chapter 5 of the present study); one of them, viz. 136 pp. Englisch.
