Taschenbuch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -The monograph is a study of the local bifurcations ofmultiparameter symplectic maps of arbitrary dimension in theneighborhood of a fixed point.The problem is reduced to astudy of critical points of an equivariant gradientbifurcation problem, using the correspondence between orbitsofa symplectic map and critical points of an actionfunctional. New results onsingularity theory forequivariant gradient bifurcation problems are obtained andthen used to classify singularities of bifurcating period-qpoints. Of particular interest is that a general frameworkfor analyzing group-theoretic aspects and singularities ofsymplectic maps (particularly period-q points) is presented.Topics include: bifurcations when the symplectic map hasspatial symmetry and a theory for the collision ofmultipliers near rational points with and without spatialsymmetry. The monograph also includes 11 self-containedappendices each with a basic result on symplectic maps. Themonograph will appeal to researchers and graduate studentsin the areas of symplectic maps, Hamiltonian systems,singularity theory and equivariant bifurcation theory. 236 pp. Englisch.…

Taschenbuch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -The language of business and management, and of infor mation technology, is being employed across all sectors of economic and social activity. In recent years computers and information technology (IT) in general have moved from being a scarce resource to being a more generally available commodity, without a corresponding increase in understanding of how the new generation of tools can be used. IT is available on individual desktops, supporting decision making and communication, but often conven tional organizations have failed to adapt, individuals lack competence and confidence, and senior managers lack both the strategic insight to develop appropriate strategies and the humility to accept that they need to learn. As each sector, whether business, education, public sec tor management or the community and voluntary sector, realizes that the potential of IT is not being exploited to the full, calls are issued for the development of new 'hybrid managers', a term coined to describe the gap in understanding and competence that is to be filled. The two editors work in the hybrid field of business information technology, which is a melting pot of ideas and experience from numerous traditional disciplines. The pace of change is such that no one individual could ever be abreast of all technical and business develop ments, but the field is now sufficiently mature for us to identify certain underlying issues and principles, and areas of research for the coming years. 300 pp. Englisch. …

Taschenbuch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -This monograph is a treatise on adjustment processes. We consider price adjustment processes in exchange economies and strategy adjustment processes in noncooperative games. In the most simple version of an exchange economy, i.e. a pure exchange economy, there exist markets on which prices are determined by the demand and supply created by a finite number of consumers willing to exchange their initial endowments in order to maximize their utilities. An equilibrium situation is attained if, for some price vector, demand equals supply in all markets. Starting from a situation not being an equi librium an adjustment process reaches an equilibrium via adaptations of prices. The advantage of the adjustment processes we will present in this monograph is that they exist and converge under far weaker assumptions than existing processes. The second subject concerns the problem of finding Nash equilibria in noncooperative games. A Nash equilibrium is a situation from which no player can improve his position by unilaterally changing his strategy. We present a new algorithm for finding such equilibria. The sequence of stra tegy vectors generated by the algorithm can be interpreted as the path followed by a strategy adjustment process. 164 pp. Englisch.…

Taschenbuch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -This book describes a series of laboratory experiments (witha total of 167 independent subjects) on forecastingbehavior. In all experiments, the time series to beforecasted was generated by an abstract econometric modelinvolving two or three artificial exogenous variables. Thisdesignprovides an optimal background for rationalexpectations and least-squares learning. As expected, thesehypotheses do not explain observed forecasting behaviorsatisfactorily. Some phenomena related to this lack ofrationality are studied: Concentration on changes ratherthan levels,underestimation of changes and overvaluation ofvolatile exogenous variables. Some learning behavior isobserved. Finally, some aspects of individual forecasts suchas prominence of 'round' number, dispersion, etc.,arestudied. 244 pp. Englisch.…

Taschenbuch. Condizione: Neu. This item is printed on demand - Print on Demand Titel. Neuware -This volume contains the background texts for an IFIPState-of-the-Art Seminar on Formal Program Development, held in early 1992 near Rio de Janeiro, Brazil. The book stems from work done by IFIP Working Group 2.1 on Algorithmic Languages and Calculi. Since 1975, the Working Group has increasingly focused on systematic approaches to programming and on appropriate concepts and notations to support such approaches. Today, the calculation of programs from specifications constitutes the central theme ofthe group's work. Thus the core interests of the group are: - formal specification of solutions to problems, and - formal development/calculationof programs from such specifications.Springer-Verlag KG, Sachsenplatz 4-6, 1201 Wien 388 pp. Englisch.…

Taschenbuch. Condizione: Neu. This item is printed on demand - Print on Demand Titel. Neuware -When John Thompson and I first began talking about finding a way to measure and cost the output of hospitals in the 1960s. we really had no concept of the need for this kind of result. In fact. if we had listened to others in the health services research community. we would rrever have begun or persisted in the task. But it seemed important to us to begin to understand what up until then seemed unexplainable - the rather strange cost behavior of hospitals. We had the benefit of Professor Martin Feld stein's observation that case-mix was certainly an important factor. but we had literally no guidance on how to make some sense out of the very large number of illnesses that beset the human race. and the very large number of different processes that obtain in our hospitals as they attempt to cope with those illnesses. We were fortunate to find a small number of curious and capable graduate students to join us in this effort. for without them we would not have had a chance of success. While many contrib uted to the ultimate outcome. it is important to single out Ronald E. Mills. Richard F. Averill. Youngsoo Shin. and Jean L. Freeman for their efforts over many years. The diagnosis-related groups (DRGs) constitute a way of identifying the normal output of hospitals in a consistent and exhaustive manner.Springer-Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 228 pp. Englisch.…
