C-XSC is a tool for the development of numerical algorithms delivering highly accurate and automatically verified results. It provides a large number of predefined numerical data types and operators. These types are implemented as C++ classes. Thus, C-XSC allows high-level programming of numerical applications in C and C++. The most important features of C-XSC are: real, complex, interval, and complex interval arithmetic; dynamic vectors and matrices; subarrays of vectors and matrices; dotprecision data types, predefined arithmetic operators with maximum accuracy; standard functions of high accuracy; multiple precision arithmetic and standard functions; rounding control for I/O data; error handling, and library of problem solving routines with automatic result verification. Thus, C-XSC makes the computer more powerful concerning the arithmetic. C-XSC is immediately usable by C programmers, easy to learn, user-extendable, and may also be combined with other tools. The book can be used as a textbook and as a reference manual. It consists of an introduction to advanced computer arithmetic, a chapter describing the programming languages C and C++, the major chapter "C-XSC Reference," sample programs, and indices.

The purpose of this book is to analyse and discuss a series of topics related with environmental conservation, land-use planning and management and impact prevention as seen from the perspective of the Earth Sciences, but with an inte- grated, interdisciplinary approach. The contributions included in the book intend to give an overview of existing problems and trends and to point out certain lines along which work and/or actions will be par- ticularly needed in the near future. In short, they intend to show where we stand now with regard to those problems and in what direction we should move. Readers will find particularly useful the brief presentation of a variety of important environmental earth science top- ics, the description of the present state of the art and the suggestions for methodological approaches to solve different problems, as well as the guidelines for action presented throughout the book.

The programming language PASCAL-XSC (PASCAL eXtension for Scientific Computation) significantly simplifies programming in the area of scientific and technical computing. PASCAL-XSC provides a large number of predefined data types with arithmetic operators and predefined functions of highestaccuracy for real and complex numbers, for real and complex intervals, and for the corresponding vectors and matrices. Thus PASCAL-XSC makes the computer more powerful concerning the arithmetic. Through an implementation in C, compilers for PASCAL-XSC are available for a large variety of computers such as personal computers, workstations, mainframes, and supercomputers. PASCAL-XSC provides a module concept, an operator concept, functions and operators with general result type, overloading of functions, procedures, and operators, dynamic arrays, access to subarrays, rounding control by the user, and accurate evaluation of expressions. The language is particularly suited for the development of numerical algorithms that deliver highly accurate and automatically verified results. A number of problem-solving routines with automatic resultverification have already been implemented. PASCAL-XSC contains Standard PASCAL. It is immediately usable by PASCAL programmers. PASCAL-XSC is easy to learn and ideal for programming education. The book can be used as a textbook for lectures on computer programming. It contains a major chapter with sample programs, exercises, and solutions. A complete set of syntax diagrams, detailed tables, and indices complete the book.

After the very successful ECC-Book on "E-conomy" this new report of the European Communication Council (ECC) analyzes from various perspectives the profound societal and economical change of the media economy, initiated by digitalization and networking. Against the background of the current media history, it highlights for example the role of the Internet hype as a pathfinder in a modified media society. The key question is concerned with how the medial future will be like. The report examines effects and new perspectives in the area of economy, society, and politics. The aspects of behavior, business models, legal and regulation questions, self-conception of society and media economy are mooted by international authors to enhance the reader's understanding of the medial future and to disclose options for action.

Mit Hilfe der induktiven Forschungsmethodik der Grounded Theory entwickelt Carolin Wolff einen Ansatz zur Erklarung der Wirkungsbeziehungen von Stabilitat und Flexibilitat in Kooperationen. Auf der Basis ihrer Mid-Range-Theorie werden Stellschrauben zur Beeinflussung des Flexibilitatsniveaus von und in Kooperationen identifiziert und Strategien fur ein wettbewerbsorientiertes Flexibilitatsmanagement von Kooperationen generiert.
