Buch. Condizione: Neu. Neuware - In the current era of health care reform, the pressures to truly manage patient care and to build effective integrated delivery systems are generating intense interest in patient care information systems. Health care institutions cannot provide seamlees access to care without seamless access to information, and they cannot manage and improve care without improved information management. Patient Care Information Systems examines how to design and implement these systems so they successfully meet the needs of physicians, nurses, and other health care providers. In one convenient reference, the authors summarize and synthesize previously disparate research and case experiences on these systems and suggest future directions based on the evolving demands of administrators and caregivers.

Buch. Condizione: Neu. Neuware -Scholars of different schools have extensively analyzed world systems as networks of communication under the fashionable heading 'globalization.' Our collected new research pushes the argument one step further. Globalization is not a homogenization of all social life on earth. It is a heterogeneous process that connects the global and the local on different levels. To understand these contemporary developments this book employs innovative concepts, strategies of research, and explanations. Globalization is a metaphor for different borderstructures, new borderlines, and conditions of membership, which emerge in a global world-system. As a world-system expands it incorporates new territories and new peoples. The process of incorporation creates frontiers or boundaries of the world-system. These frontiers or boundary zones are the locus of resistance to incorporation, ethnogenesis, ethnic transformation, and ethnocide.

Buch. Condizione: Neu. Neuware - Our two organizations, Northern Telecom Europe Limited and Oracle Corporation UK Limited, share a number of things in common. Both are striving to become world class in markets where technology is moving fast and market change is moving even faster. Both are responding urgently to the challenge of meeting the current requirements - and anticipating the future needs - of customers at the international, national and local level. We both recognize that customer and employee satisfaction now rank with market share as measures for business success. We accept that there are clear links between delighted customers and profitability, customer loyalty and long-term survival. We are committed to achieving excellence, both as business partners and as employers. There is already strong co-operation between the growing number of professionals in this field as they work together and exchange experiences for benchmarking and best practice studies. In this spirit of collaboration, we have encouraged Peter Donovan and Timothy Samler to share some of our early experiences with our customer-driven programmes and to stimulate further debate. Their book provides a wealth of guidance for any organization that has set its sights on delighting its customers and becoming customer-driven. The ten step approach to delighting customers breaks new ground and offers a blueprint for others to follow. It exemplifies the practical approach that is taken throughout the book.

Buch. Condizione: Neu. Neuware - If the truth were told, this volume and its direct antecedents must rank among the most ambitious, if not simply pretentious, endeavors imag inable, at least in the social sciences. The titles of the volume and the chapters, promising to integrate the experiences of the sense of justice and the affectional bonding of people in close relations, seem straightforward and reasonable enough. What they fail to convey, however, is the simple bald fact that we in the human social sciences have no firm grasp on either of these two fundamental experiences-what we sometimes call 'love' and 'justice. ' To begin with, even as 'scientists' committed to under standing based upon systematic propositions linking publicly observable concepts, we have no clear consensus concerning the nature of the affec tional bonds linking people in close relationships-love, intimacy, caring, mutual responsiveness, or the sense of justice, fairness, deserving, and in our efforts to under entitlement. And we are continually handicapped stand these complex, moving experiences by the persistent tendency to reduce them to manifestations of, 'nothing but,' familiar psychological or even biological processes-'secondary rewards,' 'selfish genes. ' So, why then this volume Although there are many answers to the question, probably the most germane is that the basic issues are so im portant and intriguing that the recent past has seen rather dramatic paral lel growth in social scientists' interest in these two areas-justice and close relationships.

Buch. Condizione: Neu. Neuware - During the two years since the publication of the first edition of this book, the global spread of human immunodeficiency virus/acquired immunodeficiency syndrome (HIV/AIDS) has continued. HIV was estimated by the World Health Organization (WHO) in 1993 to have at least 13 million individuals worldwide, with 1 million infected infected in the United States. HIV/AIDS in the United States has become the leading cause of death among men 25 to 44 years of age and the fifth leading cause of death among women of the same age group. Prevention of HIV infection remains a global challenge. Testing for HIV is the cornerstone for surveillance and prevention programs and for the provision of appropriate medical care for those who are infected. Such testing is equally essential to the search for effective antivirus drugs and vaccines. This second edition of AIDS Testing incorporates the most current thinking on test methodology and interpretation, some of which has changed considerably over the past two years. This edition also has been expanded to include a section consisting of six chapters on test applica tions and a section consisting of four chapters on management issues. This edition, like the first, describes in clear terms all the complex ele ments of testing, including applications, scientific principles, quality assurance, safety, and medical, ethical, and legal considerations.

Buch. Condizione: Neu. Neuware - Economic theory and empirical models suggest that economic instruments should help us to meet environmental goals at lower cost. Practical experience, however, shows that the cost savings of emission trading are smaller than expected and charges usually have had small incentive impacts. This book gives the first comprehensive review of economic theory, simulation models, and practical experience with the use of economic instruments. The book focuses on air pollution control. Part I examines theoretical aspects and simulation modeling in a national context. Part II surveys the practical experience in a variety of countries. Part III explores international issues, such as joint implementation. Because of its unique blend of theoretical and empirical research, the book will prove interesting for both economists and those interested in environmental policy.

Buch. Condizione: Neu. Neuware - This book is a collection of essays in honor of Paul Ziff written by his col leagues, students, and friends. Many of the authors address topics that Ziff has discussed in his writings: understanding, rules and regularities, proper names, the feelings of machines, expression, and aesthetic experience. Paul Ziff began his professional career as an artist, went on to study painting with J. M. Hanson at Cornell, and then studied for the Ph. D. in philosophy, also at Cornell, with Max Black. Over the next three decades he produced a series of remarkable papers in philosophy of art, culminating in 1984 with the publica tion of Antiaesthetics: An Appreciation of the Cow with the Subtile Nose. In 1960 he published Semantic Analysis, his masterwork in philosophy of lan guage. Throughout his career he made important contributions to philosophy of mind in such papers as 'The Simplicity of Other Minds' (1965) and 'About Behaviourism' (1958). In addition to his work in these areas, his lec tures at Harvard on philosophy of religion are an underground classic; and throughout his career he has continued to make art and to search for the meaning of life in the properties of prime numbers. Although his interests are wide and deep, questions about language, art, and mind have dominated his philosophical work, and it is problems in these areas that provide the topics of most of the essays in this volume.

Buch. Condizione: Neu. Neuware - Multiprocessor Execution of Logic Programs addresses the problem of efficient implementation of logic programming languages, specifically Prolog, on multiprocessor architectures. The approaches and implementations developed attempt to take full advantage of sequential implementation technology developed for Prolog (such as the WAM) while exploiting all forms of control parallelism present in logic programs, namely, or-parallelism, independent and-parallelism and dependent and-parallelism. Coverage includes a thorough survey of parallel implementation techniques and parallel systems developed for Prolog. Multiprocessor Execution of Logic Programs is recommended for people implementing parallel logic programming systems, parallel symbolic systems, parallel AI systems, and parallel theorem proving systems. It will also be useful to people who wish to learn about the implementation of parallel logic programming systems.

Buch. Condizione: Neu. Neuware - The role of orthography in reading and writing is not a new topic of inquiry. For example, in 1970 Venezky made a seminal contribution with The Structure of English Orthography in which he showed how both sequential redundancy (probable and permissible letter sequences) and rules of letter-sound correspondence contribute to orthographic structure. In 1980 Ehri introduced the concept of orthographic images, that is, the representation of written words in memory, and proposed that the image is created by an amalgamation of the word's orthographic and phonological properties. In 1981 Taylor described the evolution of orthographies in writing systems-from the earliest logographies for pictorial representation of ideas to syllabaries for phonetic representation of sounds to alphabets for phonemic representation of sounds. In 1985 Frith proposed a stage model for the role of orthographic knowledge in development of word recognition: Initially in the logographic stage a few words can be recognized on the basis of partial spelling information; in the alphabetic stage words are. recognized on the basis of grapheme-phoneme correspondence; in the orthographic stage spelling units are recognized automatically without phonological mediation. For an historical overview of research on visual processing of written language spanning the earliest records of writing to the early work in experimental psychology, see Venezky (1993).

Buch. Condizione: Neu. Neuware - Our Galactic center's proximity allows astronomers to study physical pro cesses within galactic nuclei at a level of detail that will never be possible in the more distant, but usually also more spectacular, extragalactic systems. Recent advances in instrumentation from the radio, through the submillime ter and infrared wavebands, and out to the X- and ''(-ray bands now allow observations of the Galactic Center over thirteen orders of magnitude in wave length. Our knowledge about the central few hundred parsecs of our Galaxy has consequently increased vastly over the past decade. The same new instru ments provide high resolution, high quality measurements of nearby ''normal'' galactic nuclei; that is, nuclei whose modest energy output is comparable to that of our own (and most other) galaxies. Theorists, spurred in part by the new observations, have been able to refine models of the energetics, dynam ics, and evolution of the gas and stellar systems deep within galactic nuclei.

Buch. Condizione: Neu. Neuware - In 1986 the first edition of Continuous Ambulatory Peritoneal Dialysis, edited by R. Gokal, was published. In 1989 the third edition of Peritoneal Dialysis, edited by K.D. Nolph, was published. Both books were widely recognized for their comprehensive discussion of this particular field. Rather than edit new editions of each of these books separately, two of the most prominent figures in this field have decided to combine their knowledge and enthusiasm in this single book: The Textbook of Peritoneal Dialysis. The book is unique in its detailed discussion of a complete range of topics, including new advances in our understanding of the physiology of peritoneal dialysis, peritoneal dialysis kinetics, clinical results and a chapter dealing with the concepts of intraperitoneal chemotherapy. These examples of the dynamic nature of the field further illustrate the importance of this textbook, and make it required reading for everybody working within the field of peritoneal dialysis.

Buch. Condizione: Neu. Neuware - Significant progress has been made in recent years in developing silicon nitride ceramics. The advances that have been achieved are mainly based on an increasing understanding of processing and microstructure-properties relationships. New analytical methods and high resolution transmission electron microscopy (HRTEM) coupled with extensive phase equilibria studies have provided new insights into the grain boundary region and offer the possibility to tailor the microstructure for specific applications. Because of the anticipated break-through in industrial applications there are still considerablt; research activities at industrial laboratories as well as other research centres. This volume presents the contributions to the international workshop 'Tailoring ofHigh Temperature Properties of Si3N4-Ceramics' with 60 participants from 12 countries held on 6th - 9th October 1993 at SchloB Ringberg in Germany, the conference site of the Max Planck-Society. Additionally, it contains all invited papers of the International Conference 'Silicon Nitride 93' held before the workshop on 4th - 6th October 1993 in Stuttgart/Germany. The book covers all recent research activities on silicon nitride ceramics and gives an overview with respect to recent developments.

Buch. Condizione: Neu. Neuware - Animal cell technology is a growing discipline of cell biology which aims to understand the structure, function and behaviour of differentiated animal cells, and especially the development of such abilities as are useful for industrial purposes. These developments range from clonal expansion of differentiated cells with useful abilities, to optimization of cell culture on industrial scale and modulation of the cells' abilities to produce drugs and monoclonal antibodies. The sixth volume in this series gives a complete review of today's state of the art in Japan, a country where this field is especially well advanced. It will be of interest to cell biologists, biochemists, molecular biologists, immunologists and other disciplines related to animal cell culture, working in the academic environment as well as in (biotechnology or pharmaceutical) industry.

Buch. Condizione: Neu. Neuware - Some years ago in Paisley (Scotland) the International Conference on Composite Materials, headed by Professor I. Marshall, took place. During the conference, I presented a paper on the manufacturing and properties of the Soviet Union's composite materials. Soviet industry had made great achievements in the manufacturing of composite materials for aerospace and rocket applications. For example, the fraction of composites (predominantly carbon fibre reinforced plastics) in the large passenger aircrafts Tu-204 and 11-86 is 12-15% of the structure weight. The percentage by weight share of composites in military aircraft is greater and the fraction of composites (organic fibre reinforced plastics) used in military helicopters exceeds a half of the total structure weight. The nose parts of most rockets are produced in carbon-carbon materials. In the Soviet spacecraft 'Buran' many fuselage tubes are made of boron-aluminium composites. Carbon-aluminium is used for space mirrors and gas turbine blades. These are just a few examples of applications. Many participants at the Paisley conference suggested that the substantial Soviet experience in the field of composite materials should be distilled and presented in the form of a comprehensive reference publication. So the idea of the preparation and publication of a six volume work Soviet Advanced Composites Technology, edited by Professor I. Marshall and me, was born.

Taschenbuch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -The aim of the book is to give a unified approach to new developments in discrete potential theory and infinite network theory. The author confines himself to the finite energy case, but this does not result in loss of complexity. On the contrary, the functional analytic machinery may be used in analogy with potential theory on Riemann manifolds.The book is intended for researchers with interdisciplinary interests in one of the following fields: Markov chains, combinatorial graph theory, network theory, Dirichlet spaces, potential theory, abstract harmonic analysis, theory of boundaries. 204 pp. Englisch.

Taschenbuch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -Complex Finsler metrics appear naturally in complex analysis. To develop new tools in this area, the book provides a graduate-level introduction to differential geometry of complex Finsler metrics. After reviewing real Finsler geometry stressing global results, complex Finsler geometry is presented introducing connections, Kählerianity, geodesics, curvature. Finally global geometry and complex Monge-Ampère equations are discussed for Finsler manifolds with constant holomorphic curvature, which are important in geometric function theory. Following E. Cartan, S.S. Chern and S. Kobayashi, the global approach carries the full strength of hermitian geometry of vector bundles avoiding cumbersome computations, and thus fosters applications in other fields. 196 pp. Englisch.

Taschenbuch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -The main topic of the volume is to develop efficient algorithms by which one can verify Artin's conjecture for odd two-dimensional representations in a fairly wide range. To do this, one has to determine the number of all representations with given Artin conductor and determinant and to compute the dimension of a corresponding space of cusp forms of weight 1 which is done by exploiting the explicit knowledge of the operation of Hecke operators on modular symbols. It is hoped that the algorithms developed in the volume can be of use for many other problems related to modular forms. 164 pp. Englisch.

Taschenbuch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -It is a pleasure to present this work, which has been well received in Gennan-speaking countries through four editions, to the English-speaking reader. We feel that this is a unique publication in that it contains valuable material that cannot easily-if at all-be found elsewhere. We are grateful to the authors for reading through the English version of the text, and for responding promptly (for the most part) to our queries. Several authors have supplied us, on their own initiative or at our suggestion, with revised and updated manuscripts and with supplementary English references. We have striven to achieve a translation of H andbuch flir Sternfreunde which accurately presents the qualitative and quantitative scientific principles con tained within each chapter while maintaining the flavor of the original Ger man text. Where appropriate, we have inserted footnotes to clarify material which may have a different meaning and/or application in English-speaking countries from that in Gennany. When the first English edition of this work, Astronomy: A Handbook (translated by the late A. Beer), appeared in 1975, it contained 21 chapters. This new edition is over twice the length and contains 28 authored chap ters in three volumes. At Springer's request, we have devised a new title, Compendium of Practical Astronomy, to more accurately reflect the broad spectrum of topics and the vast body of infonnation contained within these pages. 388 pp. Englisch.

This item is printed on demand - it takes 3-4 days longer - Neuware -This book makes a systematic study of the relations between the étale cohomology of a scheme and the orderings of its residue fields. A major result is that in high degrees, étale cohomology is cohomology of the real spectrum. It also contains new contributions in group cohomology and in topos theory. It is of interest to graduate students and researchers who work in algebraic geometry (not only real) and have some familiarity with the basics of étale cohomology and Grothendieck sites. Independently, it is of interest to people working in the cohomology theory of groups or in topos theory. 308 pp. Englisch.

This item is printed on demand - it takes 3-4 days longer - Neuware -Since the first edition of 'Scanning 'funneling Microscopy I' has been pub lished, considerable progress has been made in the application of STM to the various classes of materials treated in this volume, most notably in the field of adsorbates and molecular systems. An update of the most recent develop ments will be given in an additional Chapter 9. The editors would like to thank all the contributors who have supplied up dating material, and those who have provided us with suggestions for further improvements. We also thank Springer-Verlag for the decision to publish this second edition in paperback, thereby making this book affordable for an even wider circle of readers. Hamburg, July 1994 R. Wiesendanger Preface to the First Edition Since its invention in 1981 by G. Binnig, H. Rohrer and coworkers at the IBM Zurich Research Laboratory, scanning tunneling microscopy (STM) has devel oped into an invaluable surface analytical technique allowing the investigation of real-space surface structures at the atomic level. The conceptual simplicity of the STM technique is startling: bringing a sharp needle to within a few Angstroms of the surface of a conducting sample and using the tunneling cur rent, which flows on application of a bias voltage, to sense the atomic and elec tronic surface structure with atomic resolution! Prior to 1981 considerable scepticism existed as to the practicability of this approach. 296 pp. Englisch.
