Buch. Zustand: Neu. Neuware -reason for delaying its study has to do with the question of mathematical maturity. \* No use is made here of trigonometric, logarithmic, or expo nential functions except in occasional optional material indicating how such functions can be handled. A perceptive remark made by George P6lya suggests how we can simultaneously learn mathematics and learn 'about' mathematics-i.e., about the nature of mathematics and how it is developed: If the learning of mathematics reflects to any degree the invention of mathematics, it must have a place for guessing, for plausible inference. The reader will find plenty of opportunity here for guessing. The early chapters go at a gentle pace and invite the reader to enter into the spirit of the investigation. Exercises asking the reader to 'make a guess' should be taken in this spirit-as simply an invitation to speculate about what is the likely truth in a given situation without feeling any pressure to guess 'correctly'. Readers will soon realize that a matter about which they are asked to guess will likely be a topic of serious discussion later on.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 428 pp. Englisch.

Buch. Zustand: Neu. Neuware -A Course on Borel sets provides a thorough introduction to Borel sets and measurable selections and acts as a stepping stone to descriptive set theory by presenting important techniques such as universal sets, prewellordering, scales, etc. It is well suited for graduate students exploring areas of mathematics for their research and for mathematicians requiring Borel sets and measurable selections in their work. It contains significant applications to other branches of mathematics and can serve as a self- contained reference accessible by mathematicians in many different disciplines. It is written in an easily understandable style and employs only naive set theory, general topology, analysis, and algebra. A large number of interesting exercises are given throughout the text.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 284 pp. Englisch.

Buch. Zustand: Neu. Neuware -No applied mathematician can be properly trained without some basic un derstanding ofnumerical methods, Le., numerical analysis. And no scientist and engineer should be using a package program for numerical computa tions without understanding the program's purpose and its limitations. This book is an attempt to provide some of the required knowledge and understanding. It is written in a spirit that considers numerical analysis not merely as a tool for solving applied problems but also as a challenging and rewarding part of mathematics. The main goal is to provide insight into numerical analysis rather than merely to provide numerical recipes. The book evolved from the courses on numerical analysis I have taught since 1971 at the University ofGottingen and may be viewed as a successor of an earlier version jointly written with Bruno Brosowski [10] in 1974. It aims at presenting the basic ideas of numerical analysis in a style as concise as possible. Its volume is scaled to a one-yearcourse, i.e., a two-semester course, addressing second-yearstudents at a German university or advanced undergraduate or first-year graduate students at an American university.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 344 pp. Englisch.

Buch. Zustand: Neu. Neuware -Pontus Braunerhjelm and Karolina Ekholm Over recent decades, foreign direct investment (FDI) has become a major force in the global economy. The geographical pattern of capital formation, trade and technological spillovers across countries and regions, are to an in creasing extent determined by the strategies chosen by multinational firms (MNFs). Between 1982 and 1994, the rate of growth of the global FDI stock was more than twice that of gross fixed capital formation, the growth of sales by foreign affiliates of multinational firms well exceeded that of world exports, and, by 1994, the MNFs accounted for approximately 6 percent of world output (United Nations, 1997, pp. xv-xvi). The overall mechanisms behind this rapid internationalization in terms of multinational produc tion have been attributed to the dismantling of trade barriers and the deregulation of capital markets, together with the advances in information technology that have facilitated the coordination and monitoring of inter nationally dispersed production. This development carries two important implications: First, firms operate in markets characterized by much tougher competition than only a decade ago, and, second, countries and regions are involved in competition for production to a much larger extent than before. This book addresses questions related to the location and geographical dispersion of the activities by multinational firms, a topic which has be come of increasing concern to policy-makers.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 244 pp. Englisch.

Taschenbuch. Zustand: Neu. Neuware -Much current research in computer science is concerned with two questions: is a program correct And how can we improve a correct program preserving correctness This latter question is known as the refinement of programs and the purpose of this book is to consider these questions in a formal setting. In fact, correctness turns out to be a special case of refinement and so the focus is on refinement. Although a reasonable background knowledge is assumed from mathematics and CS, the book is a self-contained introduction suitable for graduate students and researchers coming to this subject for the first time. There are numerous exercises provided of varying degrees of challenge.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 540 pp. Englisch.

Buch. Zustand: Neu. Neuware -Least squares estimation, when used appropriately, is a powerful research tool. A deeper understanding of the regression concepts is essential for achieving optimal benefits from a least squares analysis. This book builds on the fundamentals of statistical methods and provides appropriate concepts that will allow a scientist to use least squares as an effective research tool.Applied Regression Analysis is aimed at the scientist who wishes to gain a working knowledge of regression analysis. The basic purpose of this book is to develop an understanding of least squares and related statistical methods without becoming excessively mathematical. It is the outgrowth of more than 30 years of consulting experience with scientists and many years of teaching an applied regression course to graduate students. Applied Regression Analysis serves as an excellent text for a service course on regression for non-statisticians and as a reference for researchers. It also provides a bridge between a two-semester introduction to statistical methods and a thoeretical linear models course.Applied Regression Analysis emphasizes the concepts and the analysis of data sets. It provides a review of the key concepts in simple linear regression, matrix operations, and multiple regression. Methods and criteria for selecting regression variables and geometric interpretations are discussed. Polynomial, trigonometric, analysis of variance, nonlinear, time series, logistic, random effects, and mixed effects models are also discussed. Detailed case studies and exercises based on real data sets are used to reinforce the concepts. The data sets used in the book are available on the Internet.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 682 pp. Englisch.

Buch. Zustand: Neu. Neuware -Applied Stochastic Models and Control for Finance and Insurance presents at an introductory level some essential stochastic models applied in economics, finance and insurance. Markov chains, random walks, stochastic differential equations and other stochastic processes are used throughout the book and systematically applied to economic and financial applications. In addition, a dynamic programming framework is used to deal with some basic optimization problems.The book begins by introducing problems of economics, finance and insurance which involve time, uncertainty and risk. A number of cases are treated in detail, spanning risk management, volatility, memory, the time structure of preferences, interest rates and yields, etc. The second and third chapters provide an introduction to stochastic models and their application. Stochastic differential equations and stochastic calculus are presented in an intuitive manner, and numerous applications and exercises are used to facilitate their understanding and their use in Chapter 3. A number of other processes which are increasingly used in finance and insurance are introduced in Chapter 4. In the fifth chapter, ARCH and GARCH models are presented and their application to modeling volatility is emphasized. An outline of decision-making procedures is presented in Chapter 6. Furthermore, we also introduce the essentials of stochastic dynamic programming and control, and provide first steps for the student who seeks to apply these techniques. Finally, in Chapter 7, numerical techniques and approximations to stochastic processes are examined.This book can be used in business, economics, financial engineering and decision sciences schools for second year Master's students, as well as in a number of courses widely given in departments of statistics, systems and decision sciences.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 348 pp. Englisch.

Buch. Zustand: Neu. Neuware -My initial interest in the Solifugae (camel-spiders) stems from an incident that occurred in the summer of 1986. I was studying the behavioral ecology of spider wasps of the genus Pepsis and their interactions with their large theraphosid (tarantula) spider hosts, in the Chihuahuan Desert near Big Bend National Park, Texas. I was monitoring a particular tarantula burrow one night when I noticed the resident female crawl up into the burrow entrance. Hoping to take some photographs of prey capture, I placed a cricket near the entrance and waited for the spider to pounce. Suddenly, out of the comer of my eye appeared a large, rapidly moving yellowish form which siezed the cricket and quickly ran off with it until it disappeared beneath a nearby mesquite bush. So suddenly and quickly had the sequence of events occurred, that I found myself momentarily startled. With the aid of a headlamp I soon located the intruder, a solifuge, who was already busy at work macerating the insect with its large chelicerae (jaws). When I attempted to nudge it with the edge of my forceps, it quickly moved to another location beneath the bush. When I repeated this maneuver, the solifuge dropped the cricket and lunged at the forceps, gripping them tightly in its jaws, refusing to release them until they were forcefully pulled away.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 316 pp. Englisch.
