Buch. Condición: Neu. Neuware -Reasoning is an integral part of intelligent systems in fields like databases, logic programming, robotics, knowledge engineering, human/computer interfaces, programming environments, etc. In reality any such system has to cope with a changing world and its dynamics. Hence it is of great importance that reasoning must account for coping with change in order to be truly useful in practice.The book comprises several contributions to current ways of approaching this problem. On the one hand it surveys and synthesizes recent research work, while on the other hand new research results are included. Among the topics treated are logics for reasoning about actions and planning, belief revision and the reconciliation of logically conflicting inputs, resolving of conflicts by merging of knowledge and issues in the evolution in object-oriented databases.The book is aimed at the researcher and advanced student active in this field.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 300 pp. Englisch.

Taschenbuch. Condición: Neu. Neuware -Distance determination - finding out how far away different astronomical objects are - is an essential and currently highly topical subject in astronomy. A great deal of progress has been made during the last part of the 20th century. Measuring the Universe provides a unified treatment of the various techniques used for distance determination. It begins by describing methods to measure distances on Earth then gradually climbs the 'distance ladder' to enable us to estimate the distance to the farthest objects, ending with a discussion of particle horizons within an expanding and inflationary universe. Aimed at first-year undergraduates of astronomy and astrophysics, the book emphasises general physical principles rather than mathematical detail. The text is enhanced and complemented by the use of many worked examples, and questions and problem solving exercises at the end of each chapter.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 360 pp. Englisch.

Buch. Condición: Neu. Neuware -Coastal aquifers serve as major sources for freshwater supply in many countries around the world, especially in arid and semi-arid zones. Many coastal areas are also heavily urbanized, a fact that makes the need for freshwater even more acute. Coastal aquifers are highly sensitive to disturbances. Inappropriate management of a coastal aquifer may lead to its destruction as a source for freshwater much earlier than other aquifers which are not connected to the sea. The reason is the threat of seawater intrusion. In many coastal aquifers, intrusion of seawater has become one of the major constraints imposed on groundwater utilization. As sea water intrusion progresses, existing pumping wells, especially those close to the coast, become saline and have to be abandoned. Also, the area above the intruding seawater wedge is lost as a source of natural replenishment to the aquifer. Despite the importance of this subject, so far there does not exist a book that integrates our present knowledge of seawater intrusion, its occurrences, physical mechanism, chemistry, exploration by geo physical and geochemical techniques, conceptual and mathematical modeling, analytical and numerical solution methods, engineering measures of combating seawater intrusion, management strategies, and experience learned from case studies. By presenting this fairly comprehensive volume on the state-of-the-art of knowledge and ex perience on saltwater intrusion, we hoped to transfer this body of knowledge to the geologists, hydrologists, hydraulic engineers, water resources planners, managers, and governmental policy makers, who are engaged in the sustainable development of coastal fresh ground water resources.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 648 pp. Englisch.

Buch. Condición: Neu. Neuware -Silicon and silicon compounds have contributed decisively to the technical progress. Technical applications range from mass commodities to highly sophisticated special materials, from ceramics to polymers, from medicine to microelectronics. To keep pace with scientific and technical developments Germany and Austria have established national priority programs, strongly linked to each other as well as to some Swiss groups.At mid-term of the German program and the end of the first funding period of the Austrian program the results are summarized in this special edition of the journal Monatshefte für Chemie/Chemical Monthly, giving an excellent overview of the current chemical (and partly physical) acitivites in the joint Austrian/German/Swiss program.The contributions cover topical and interdisciplinary developments in the following areas:¿ new phenomena in compounds with Si-Si bonds: transitions between molecular compounds and solids, cyclosilanes, polysilanes, silicides, amorphous hydrogenated silicon¿ novel silicon-oxygen systems: functionalized sol-gel compounds, spherosiloxanes, siloxene¿ compounds with low- and high-coordinated silicon¿ new spectroscopic and analytical techniques for the characterization of molecular and polymeric silicon compounds. 252 pp. Englisch.

Buch. Condición: Neu. Neuware - Newspapers: A Lost Cause describes the recent history of newspaper firms in the United States and The Netherlands, and attempts to assess the chances of survival of the printed newspaper. The changing competitive media landscape and the challenges of today's newspaper organisations, including the impact of the Internet on the news industry, are described and analysed. The author argues that although the printed newspaper will not be replaced overnight by (new) competing media, the traditional business model of newspapers is being eroded slowly but steadily. A healthy newspaper industry and prospering newspaper firms can only exist, if management - including journalists and marketeers - focus their attention on changing the newspaper organisation and capitalise more intensively on its core assets and skills.

Buch. Condición: Neu. Neuware -The definite treatment ofaortic disorders goes back to the resection ofisthmic coarctation by Clarence Crafoord in 1944. It took another third of a century until all portionsofthe aortabecameaccessible to highly standardized surgery. This progress, delayed as it was in relation to most other cardiovascular in terventions, depended on the availability of safe protective methods for the heart and central nervous system, of reliable vascular grafts and atraumatic instruments, novel suture material and tissue adhesives. The development ofadvanced surgical techniques went hand in hand with, and depended upon, the emergence of proper diagnostic tools, starting with aortography andultimately culminating inCT-scanning, transesophageal echo cardiography and magnetic resonance imaging. These tools now allow for the rational planning and conductofany aortic intervention which may be surgical or, more recently, catheter-guided. Nienaber's and Fattori's new book aptly is addressing both the diagnos tic procedure as well as the treatment of aortic disease. The authors are well known experts in the fields of advanced diagnostics of aortic pathology, both spearheading a remarkably innovative group of aortic interventionalists as well. On account of their expertise, their chapters are able to answer any question rising in conjunction with these subjects.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 300 pp. Englisch.

Buch. Condición: Neu. Neuware -The Sapporo International Symposium on 'Recent Advances in Nitric Oxide Research' was held in Sapporo, Japan, in 1997, following the Fifth International Meeting on the Biology of Nitric Oxide in Kyoto, Japan, organized by Dr. Salvador Moncada, Dr. Noboru Toda, and Dr. Hiroshi Maeda. The field of nitric oxide research continues to expand rapidly, and our understanding of the physiological and pathophysiological roles of NO has increased greatly. The Kyoto Meeting was stimulating and informative, providing impetus for the Sapporo Symposium, which I had the great honor to organize. To communicate the information from these events, Dr. Ichiro Sakuma and I decided to publish this book. The contents of its chapters were contributed by the participants who were active at the Sapporo symposium and cover the majority of the presentations made during that symposium. Dr. Csaba Szabo of Children's Hospital Medical Center in Cincinnati (U. S. A. ) reviews the roles of peroxynitrite and poly(ADP-ribose)synthetase in shock, inflammation, and reperfusion injury, and Dr. David A. Geller and his colleagues of the University of Pittsburgh (U.

Taschenbuch. Condición: Neu. Neuware -The mid-1980s saw the discovery of logical tools that make it possible to model changes in belief and knowledge in entirely new ways. These logical tools turned out to be applicable to both human beliefs and to the contents of databases. Philosophers, logicians, and computer scientists have contributed to making this interdisciplinary field one of the most exciting in the cognitive scientists - and one that is expanding rapidly.This, the first textbook in the new area, contains both discursive chapters with a minimum of formalism and formal chapters in which proofs and proof methods are presented. Using different selections from the formal sections, according to the author's detailed advice, allows the book to be used at all levels of university education. A supplementary volume contains solutions to the 210 exercises.The volume's unique, comprehensive coverage means that it can also be used by specialists in the field of belief dynamics and related areas, such as non-monotonic reasoning and knowledge representation.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 416 pp. Englisch.

Buch. Condición: Neu. Neuware -Do the antitrust laws have a place in the digital economy or are they obsolete That is the question raised by the government's legal action against Microsoft, and it is the question this volume is designed to answer.America's antitrust laws were born out of the Industrial Revolution. Opponents of the antitrust laws argue that whatever merit the antitrust laws may have had in the past they have no place in a digital economy. Rapid innovation makes the accumulation of market power practically impossible. Markets change too quickly for antitrust actions to keep up. And antitrust remedies are inevitably regulatory and hence threaten to `regulate business'.A different view - and, generally, the view presented in this volume - is that antitrust law can and does have an important and constructive role to play in the digital economy. The software business is new, it is complex, and it is rapidly moving. Analysis of market definition, contestibility and potential competition, the role of innovation, network externalities, cost structures and marketing channels present challenges for academics, policymakers and judges alike. Evaluating consumer harm is problematic. Distinguishing between illegal conduct and brutal - but legitimate - competition is often difficult.Is antitrust analysis up to the challenge This volume suggests that antitrust analysis `still works'. In stark contrast to the political rhetoric that has surrounded much of the debate over the Microsoft case, the articles presented here suggest neither that Microsoft is inherently bad, nor that it deserves a de facto exemption from the antitrust laws. Instead, they offer insights - for policymakers, courts, practitioners, professors and students of antitrust policy everywhere - on how antitrust analysis can be applied to the business of making and marketing computer software.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 316 pp. Englisch.

Buch. Condición: Neu. Neuware -Scientists and clinicians attending the last 'New Directions in Antiviral Therapy' conference in late 1994 could hardly have predicted the revolution in the management of patients with HIV infection that has occurred since. Two new classes of antiretrovirals have been licensed, the second-site RT inhibitors and the protease inhibitors; the long in cubation period of active HIV infection, when the infection is clinically latent, is now un derstood to be a period of intense viral replication and turnover of CD4 lymphocytes; measurements of HI V RNA concentration in plasma have been shown to be essential tools for monitoring the course of HIV infection, deciding when to treat, and assessing the re sults of treatment; and finally, combinations of antiretrovirals, particularly combinations including protease inhibitors, have been shown to have dramatically beneficial effects on patients with HIV infection. These advances, coupled with new drugs for the management of herpesvirus infections, have made dramatic differences in the quality and length of life of HIV-infected patients. Additional advances have been made since 1994 in the prevention or management of influenza virus (zanamavir), respiratory syncytial virus (palvizumab), hepatitis B virus (lamivudine and famciclovir), and enterovirus infections (pleconaril). It is difficult to re member that only slightly more than a decade ago there were only a handful of antiviral agents available (none of which were antiretrovirals), and a number of those were either highly toxic, of dubious efficacy, or both.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 282 pp. Englisch.

Buch. Condición: Neu. Neuware -Mongolia is an expansive land-locked country, tilted by tectonic forces to the North, that experiences extremes of continental climate. Moisture-carrying wind currents are scarce so that the land has extended highs and lows in its environment. Culturally the people are mostly nomadic, having been sustained for centuries by an economy based on domestic livestock grazing. There is a saying that, `As the noses go, so goes Mongolia', referring to the domesticated grazing noses of sheep, goats, camels, yaks or horses, and wild ungulates such as gazelles. The vast fenceless steppes of Mongolia furnish the vegetation for grazing. With such extremes in climate it is clear that the vegetation must be resilient and dynamic to cope with the dictates of its extremely harsh environments.Pollen profiles from lakes, plant macrofossils and other data over the last 15,000 years show the dynamic nature of Mongolian vegetation. Currently Mongolian society is experiencing much human-driven economic development which increases pressure on its vegetation. The Great Khural Laws of 1995 forcefully addressed such environmental concerns with the expanded establishment of National Reserves and Parks. But continued effort and vigilance must be expended to insure that Mongolian society will continue to be sustained by its vegetation. This book highlights work such as conserving and restoring plant diversity in various ecosystems and makes recommendations for sustaining the vegetation basis of the nomadic Mongolian society.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 252 pp. Englisch.

Buch. Condición: Neu. Neuware -`Electric energy must be treated as a commodity which can be bought, sold, and traded, taking into account its time- and space-varying values and costs.` Spot Pricing of Electricity, Schweppe et al, 1988.Computational Auction Mechanisms for Restructured Power Industry Operation outlines the application of auction methods for all aspects of power system operation, primarily for a competitive environment. A complete description of the industry structure as well as the various markets now being formed is given. A thorough introduction to auction basics is included to explain how auctions have grown in other industries. Auction methods are compared to classical techniques for power system analysis, operations, and planning. The traditional applications of economic dispatch, optimal power flow and unit commitment are compared to auction mechanisms. Algorithms for auctions using linearized power flow equations, DC power flow equations, and AC power flow equations are included. The bundling of supportive services, known as ancillary services within the United States, is discussed. Extensions to the basic auction algorithms for inclusion of supportive services as well as algorithms for scheduling and bidding on generation for GENCOs or independent power producers are presented. Algorithms for scheduling and contracting with customers are also presented for energy service companies. An introduction to the various commodity and financial market products includes the use of futures and options for GENCOs. The material is useful for students performing research on the new business environment based on competition. Regulators will find information on initial methods of designing and evaluating market systems, and power exchange and financial analysts will find information on the interdependence of markets and power system-based techniques for risk management. This information compares the new business environment solutions with old business environment solutions.Computational Auction Mechanisms for Restructured Power Industry Operation provides a first introduction to how electricity will be traded as a commodity in the future.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 356 pp. Englisch.

Buch. Condición: Neu. Neuware -Both the beauty and interest of fractures and fracture networks are easy to grasp, since they are abundant in nature. An example is the road from Digne to Nice in the south of France, with an impressive number and variety of such structures: the road for the most part, goes through narrow valleys with fast running streams penetrating the rock faces; erosion is favored by the Mediterranean climate, so that rocks are barely covered by meager vegetation. In this inhospitable and sterile landscape, the visitor can im mediately discover innumerable fractures in great masses which have been distorted by slow, yet powerful movements. This phenomenon can be seen for about 100 kilometers; all kinds of shapes and combinations are repre sented and can be observed either in the mountain itself or in the man-made cliffs and excavations, resulting from improvements made to the road. In the same region, close to the Turini Pass, a real large scale hydrody namic experiment is taking place -a source which is situated on the flank on the mountain, has been equiped with a tap; if the tap is open, water flows through the tap only, but when it is closed, then the side of the mountain releases water in a matter of seconds. Other outlets are also influenced by this tap, such as a water basin situated a few hundred meters away.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 452 pp. Englisch.

Buch. Condición: Neu. Neuware -This collection of essays represents the work produced in the course of a three-year project funded by the Commission of the European Communities under the Biomed I programme, on the ethics of genetic screening, entitled 'Genetic screening: ethical and philosophical perspectives, with special reference to multifactorial diseases'. The short title of the project was Euroscreen, thereafter known as Euroscreen I, in the light of the fact that a second project on genetic screening was subsequently funded. The project was multinational and multidisciplinary, and had as its objectives to examine the nature and extent of genetic screening programmes in different European countries; to analyse the social policy response to these developments in different countries; and to explore the applicability of normative ethical frameworks to the issues. The project was led by a core group who had oversight of the project and members of which have acted as editors for this volume. Darren Shickle edited the first section; Henk ten Have the second; Ruth Chadwick and Urban Wiesing the third and final part. The volume opens with an overview of genetic screening and the principles available for addressing developments in the field, with special reference to the Wilson and Jungner principles on screening. The first of the three major sections thereafter includes papers on the state of the art in different countries, together with some analysis of social context and policy.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 272 pp. Englisch.

Kinds and patterns of intraspecific variation are considered, including quantitative and especially molecular characteristics. Throughout, an attempt is made to relate aspects of fungal population biology to biology as a whole.

Buch. Condición: Neu. Neuware - The protection of the environment is one of the most important problems facing us today. Reliable and robust strategies for keeping pollution caused by harmful chemicals under safe levels have to be developed and used routinely. Large mathematical models, incorporating all important physical and chemical processes, can solve this task, but the computational burden is huge. The papers presented here describe some of the difficult problems that have to be solved during the development of large scale air pollution models, and different ways to solve them. The work involves combined research by specialists in the fields of environmental modelling, numerical analysis and scientific computing. Further, if models are to run in real time (which may be vital in the case of accidental hazardous releases), then new and efficient methods that harness the potential power of parallel supercomputers must be developed, so that actual computing speed starts to approach the maximum available performance. The articles are understandable by specialists in the field of air pollution modelling, as well as specialists in the many other related areas.

Buch. Condición: Neu. Neuware -The conference on Random Dynamical Systems took place from April 28 to May 2, 1997, in Bremen and was organized by Matthias Gundlach and Wolfgang Kliemann with the help of th'itz Colonius and Hans Crauel. It brought together mathematicians and scientists for whom mathematics, in particular the field of random dynamical systems, is of relevance. The aim of the conference was to present the current state in the theory of random dynamical systems (RDS), its connections to other areas of mathematics, major fields of applications, and related numerical methods in a coherent way. It was, ho~vever, not by accident that the conference was centered around the 60th birthday of Ludwig Arnold. The theory of RDS o~ves much of its current state and status to Ludwig Arnold. Many aspects of the theory, a large number of results, and several substantial contributions were accomplished by Ludwig Arnold. An even larger number of contributions has been initiated by him. The field be- fited much from his enthusiasm, his openness for problems not completely aligned with his o~vn research interests, his ability to explain mathematics to researchers from other sciences as well as his ability to get mathema- clans interested in problems from applications not completely aligned with their research interests. In particular, a considerable part of the impact stochastics had on physical chemistry as well as on engineering goes back to Ludwig Arnold. He built up an active research group, kno~vn as 'the Bremen group'.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 472 pp. Englisch.

Buch. Condición: Neu. Neuware -Ceramic materials are widely used as components in a great variety of applications. They are attractive due to their good high temperature strength, high wear resistance, good corrosion restistance and other special physical properties. Their major drawback is their brittleness and the large scatter of their mechanical properties. This book describes failure phenomena in ceramic materials under mechanical loading, methods for determining the material properties, and the principles that one should apply when selecting a material. The fracture-mechanical and statistical principles and their use in describing the scatter of strength and lifetime are also covered. Special chapters are devoted to creep behaviour, multiaxial failure criteria and thermal shock behaviour.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 312 pp. Englisch.

Buch. Condición: Neu. Neuware -The subject of this book is stochastic partial differential equations, in particular, reaction-diffusion equations, Burgers and Navier-Stokes equations and the corresponding Kolmogorov equations. For each case the transition semigroup is considered and irreducibility, the strong Feller property, and invariant measures are investigated. Moreover, it is proved that the exponential functions provide a core for the infinitesimal generator. As a consequence, it is possible to study Sobolev spaces with respect to invariant measures and to prove a basic formula of integration by parts (the so-called 'carré du champs identity'. Several results were proved by the author and his collaborators and appear in book form for the first time. Presenting the basic elements of the theory in a simple and compact way, the book covers a one-year course directed to graduate students in mathematics or physics. The only prerequisites are basic probability (including finite dimensional stochastic differential equations), basic functional analysis and some elements of the theory of partial differential equations.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 302 pp. Englisch.

Buch. Condición: Neu. Neuware -Aggregation of individual opinions into a social decision is a problem widely observed in everyday life. For centuries people tried to invent the `best' aggregation rule. In 1951 young American scientist and future Nobel Prize winner Kenneth Arrow formulated the problem in an axiomatic way, i.e., he specified a set of axioms which every reasonable aggregation rule has to satisfy, and obtained that these axioms are inconsistent. This result, often called Arrow's Paradox or General Impossibility Theorem, had become a cornerstone of social choice theory. The main condition used by Arrow was his famous Independence of Irrelevant Alternatives. This very condition pre-defines the `local' treatment of the alternatives (or pairs of alternatives, or sets of alternatives, etc.) in aggregation procedures.Remaining within the framework of the axiomatic approach and based on the consideration of local rules, Arrovian Aggregation Models investigates three formulations of the aggregation problem according to the form in which the individual opinions about the alternatives are defined, as well as to the form of desired social decision. In other words, we study three aggregation models. What is common between them is that in all models some analogue of the Independence of Irrelevant Alternatives condition is used, which is why we call these models Arrovian aggregation models.Chapter 1 presents a general description of the problem of axiomatic synthesis of local rules, and introduces problem formulations for various versions of formalization of individual opinions and collective decision. Chapter 2 formalizes precisely the notion of `rationality' of individual opinions and social decision. Chapter 3 deals with the aggregation model for the case of individual opinions and social decisions formalized as binary relations. Chapter 4 deals with Functional Aggregation Rules which transform into a social choice function individual opinions defined as choice functions. Chapter 5 considers another model &endash; Social Choice Correspondences when the individual opinions are formalized as binary relations, and the collective decision is looked for as a choice function. Several new classes of rules are introduced and analyzed.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 260 pp. Englisch.

Neuware -How can established models and methods be employed for the understanding and change of organisations One of the key issues presented in this book is bridging the communication gap between business leaders and IT experts in companies and public services. This is facilitated by combining different models for the development of corporate strategies, business processes and information support. The leading idea behind this book is to present different perspectives on business modelling, based on established theories and practical experiences. The book offers advanced knowledge and relevant information on the key issues in business modelling for today`s organisations.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 352 pp. Englisch.

Buch. Condición: Neu. Neuware -This volume is a collection of my essays on philosophy of logic from a phenomenological perspective. They deal with the four kinds of logic I have been concerned with: formal logic, transcendental logic, speculative logic and hermeneutic logic. Of these, only one, the essay on Hegel, touches upon 'speculative logic', and two, those on Heidegger and Konig, are concerned with hermeneutic logic. The rest have to do with Husser! and Kant. I have not tried to show that the four logics are compatible. I believe, they are--once they are given a phenomenological underpinning. The original plan of writing an Introduction in which the issues would have to be formulated, developed and brought together, was abandoned in favor of writing an Introductory Essay on the 'origin'- in the phenomenological sense -of logic. J.N.M. Philadelphia INTRODUCTION: THE ORIGIN OF LOGIC The question of the origin of logic may pertain to historical origin (When did it all begin Who founded the science of logic ), psychological origin (When, in the course of its mental development, does the child learn logical operations ), cultural origin (What cultural - theological, metaphysical and linguisti- conditions make such a discipline as logic possible ), or transcendental constitutive origin (What sorts of acts and/or practices make logic possible ).Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 252 pp. Englisch.

Buch. Condición: Neu. Neuware -PROF. DR. anus PEETERS PRESIDENT- ExECUTIVE DIRECTOR, POLICY RESEARCH CORPORATION N. V. The 'Strategies for Global and Regional Ports' confirms that container shipping in the wider Caribbean is in for tumultuous development in the years to come. One of the driving forces behind the momentous changes expected in the provision of maritime liner services in the region, is the growing reliance by major container carriers on multi-layered transhipment concepts and hub ports. Given its favourable location at the junction of North-South and East West trades, the Caribbean region is increasingly becoming a crucial factor in the service pattern of major carriers. As a result, global terminal operating companies such as Hutchison Port Holdings and Stevedoring Services of America, are already tapping the potential for developing port activity that was, until recently, dormant. In anticipation of the new shipping patterns to emerge in the coming months and years, major political decisions with respect to shipping and port development need to be taken by Caribbean Governments. Many of these decisions will be made under pressure of well meaning lobbies, but which do not always have the necessary insight into liner shipping developments. The Netherlands Antilles is one of those nations whose ports are at a crossroads and may either become regional hub ports or turn into feeder ports. In view of the changes in the Caribbean maritime geography, the Ministry of Traffic and Transport of the Netherlands Antilles commissioned Policy Research Corporation N.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 252 pp. Englisch.

Buch. Condición: Neu. Neuware -Companies must confront an increasingly competitive environment with lean, flexible and market oriented structures. Therefore companies organize themselves according to their business processes. These processes are more and more often designed, implemented and managed based on standard software, mostly ERP or SCM packages. This is the first book delivering a complete description of a business driven implementation of standard software packages, accelerated by the use of reference models and other information models. The use of those models ensures best quality results and speeds up the software implementation. The book discusses how companies can optimize business processes and realize strategic goals with the implementation of software like SAP R/3, Oracle, Baan or Peoplesoft. It also includes the post implementation activities. The book cites numerous case studies and outlines each step of a process oriented implementation, including the goals, procedures and necessary methods and tools.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 252 pp. Englisch.
