Taschenbuch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -In a modern economy, production and competition require internal interaction of individuals in firms. The book provides a systematic treatment of the macroeconomic consequenses of this fact. For this purpose the concept of a two-stage monopolistic competition equilibrium is introduced into macroeconomic theory. Firms choose the capacity to organize internal interaction at stage 1 and compete at stage 2. The concept allows a rigorous analysis of the provision of work places and the economic determinants of the employable work force. The book explains why in the equilibrium of a market economy, even under flexible wages, no jobs may be provided for people who are employable from an efficiency point of view. The economic determinants of equilibrium employment covered by the analysis of the book are: New forms of work organization, changes in the skill structure of the labor force, market power of key factors for organization, expections of investors and international capital movements. 206 pp. Englisch.

Taschenbuch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -A comprehensive introduction to mathematical structures essential for Rough Set Theory. The book enables the reader to systematically study all topics of rough set theory. After a detailed introduction in Part 1 along with an extensive bibliography of current research papers. Part 2 presents a self-contained study that brings together all the relevant information from respective areas of mathematics and logics. Part 3 provides an overall picture of theoretical developments in rough set theory, covering logical, algebraic, and topological methods. Topics covered include: algebraic theory of approximation spaces, logical and set-theoretical approaches to indiscernibility and functional dependence, topological spaces of rough sets. The final part gives a unique view on mutual relations between fuzzy and rough set theories (rough fuzzy and fuzzy rough sets). Over 300 excercises allow the reader to master the topics considered. The book can be used as a textbook and as a reference work. 534 pp. Englisch.

Taschenbuch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -Classical probability theory and mathematical statistics ap- pear sometimes too rigid for real life problems, especially while dealing with vague data or imprecise requirements. These problems have motivated many researchers to 'soften' the classical theory. Some 'softening' approaches utilize concepts and techniques developed in theories such as fuzzy sets theory, rough sets, possibility theory, theory of be- lief functions and imprecise probabilities, etc. Since in- teresting mathematical models and methods have been proposed in the frameworks of various theories, this text brings to- gether experts representing different approaches used in soft probability, statistics and data analysis. 384 pp. Englisch.

Neuware -Since the late 1980s and the beginning of the 1990s, the Commonwealth of Independent States (CIS) and Central and Eastern European Countries (CEECs) have been involved in the transition process. This book compares the progress of some of these economies in transition and analyses their growth potential. The focus lies on the special role that foreign trade liberalisation and foreign direct investment plays in economic growth. Since foreign trade and foreign direct investment are important channels of technology transfer they can substantially contribute to a higher level of economic growth. Based on the gravity model this book investigates potential in foreign trade and foreign direct investment for selected CIS and CEECs with developed OECD economies. Policy options for some of these countries are discussed including issues of foreign trade, foreign direct investment, structural adjustment, and economic growth.Physica Verlag, Tiergartenstr. 17, 69121 Heidelberg 304 pp. Englisch.

Buch. Condizione: Neu. This item is printed on demand - Print on Demand Titel. Neuware -Geometric properties and relations play central roles in the description and processing of spatial data. The properties and relations studied by mathematicians usually have precise definitions, but verbal descriptions often involve imprecisely defined concepts such as elongatedness or proximity. The methods used in soft computing provide a framework for formulating and manipulating such concepts. This volume contains eight papers on the soft definition and manipulation of spatial relations and gives a comprehensive summary on the subject.Physica Verlag, Tiergartenstr. 17, 69121 Heidelberg 224 pp. Englisch.

Buch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -Fuzziology studies the fuzziness inherent in what we know about ourselves, the sources and nature of our experience, our thoughts and feelings, drives for understanding and urges to create and realise our potential. This kind of fuzziness is at the core of our existence, at the essence of our humanness. It affects any field of human activity, be it mathematical study of fuzzy equations and fuzzy integrals; engineering design and implementation of fuzzy logic-based methodologies; fuzzy control systems or fuzzy robots. Social fuzziology investigates the role of fuzziness in understanding the dynamic complexity of human existence in the social world. It is a study of the nexus between the complex demands of life -individual and social -and the fuzziness of thinking. Since human evolution over 2 billion years has seen the co-evolution of social complexity with human language and thought, it is likely that the fuzziness of language and thought is especially intimately formed by the demands of social complexity, just as social complexity is sustained by the inherent fuzziness of language and thought. Social fuzziology is not simply one field of application of fuzziology. Given the initial state of the development of fuzziology, social fuzziology needs to develop hand in hand with fuzziology, each helping to advance the other. 188 pp. Englisch.

Buch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -Bei der Gründung von Unternehmen ist in den letzten Jahren ein Trend zu Teamgründungen zu beobachten. Ob Gründerteams erfolgreicher sind als Einzelgründer wird kontrovers diskutiert. Viele Vorteile, wie die Kombination von verschiedenartigen Fähigkeiten und Wissen sprechen dafür. Gefahren liegen dagegen in der Qualität des Zusammenspiels der Partner. Die Analyse von mehr als 150 partnerschaftlich gegründeten Unternehmen zeigt, unter welchen Umständen Gründerteams besonders erfolgreich sind. Wie erfolgversprechend die eigene Interaktionsstrategie ist, kann mithilfe eines Analyseinstruments überprüft werden. Die zugrundegelegten Zielwerte sind aus den Ergebnissen der Untersuchung abgeleitet und können für die Besetzung und Finanzierung von Gründerteams wertvolle Hinweise geben. 170 pp. Deutsch.
