Buch. Condición: Neu. Neuware - This book deals with a basic problem arising within the Bayesian approach 1 to scientific methodology, namely the choice of prior probabilities. The problem will be considered with special reference to some inference methods used within Bayesian statistics (BS) and the so-called theory of inductive 2 probabilities (T/P). In this study an important role will be played by the assumption - defended by Sir Karl Popper and the supporters of the current verisimilitude theory (VT) - that the cognitive goal of science is the achievement of a high degree of truthlikeness or verisimilitude. A more detailed outline of the issues and objectives of the book is given in Section 1. In Section 2 the historical background of the Bayesian approach and the verisimilitude theory is briefly illustrated. In Section 3, the methods used in TIP and BS for making multinomial inference~ are considered and some conceptual relationships between TIP and BS are pointed out. In Section 4 the main lines of a new approach to the problem of the choice of prior probabilities are illustrated. Lastly, in Section 5 >the structure of the book is described and a first explanation of some technical terms is provided.…

Buch. Condición: Neu. Neuware - This book aims to present, in a unified approach, a series of mathematical results con cerning triangular norm-based measures and a class of cooperative games with Juzzy coalitions. Our approach intends to emphasize that triangular norm-based measures are powerful tools in exploring the coalitional behaviour in 'such games. They not and simplify some technical aspects of the already classical axiomatic the only unify ory of Aumann-Shapley values, but also provide new perspectives and insights into these results. Moreover, this machinery allows us to obtain, in the game theoretical context, new and heuristically meaningful information, which has a significant impact on balancedness and equilibria analysis in a cooperative environment. From a formal point of view, triangular norm-based measures are valuations on subsets of a unit cube [0, 1]X which preserve dual binary operations induced by trian gular norms on the unit interval [0, 1]. Triangular norms (and their dual conorms) are algebraic operations on [0,1] which were suggested by MENGER [1942] and which proved to be useful in the theory of probabilistic metric spaces (see also [WALD 1943]). The idea of a triangular norm-based measure was implicitly used under various names: vector integrals [DVORETZKY, WALD & WOLFOWITZ 1951], prob abilities oj Juzzy events [ZADEH 1968], and measures on ideal sets [AUMANN & SHAPLEY 1974, p. 152].…

Buch. Condición: Neu. Neuware - P.P. Wong ABSTRACT Tourism is environmentally dependent. The unique character ofcoastal areas gives rise to a distinctive tourist development. Although accounts on the impacts ofcoastal tourism can be found in works relating to tourism in general, there are few works specifically on coastal tourism. This present volume focuses on the physical environment of coastal tourism, particularly the geomorphological aspects. The papers deal with basic aspects of the coastal environment for tourism, methodologies for assessing the coastal environment for tourism and empirical studies of various types of coastal environment with tourism development. The resultinggeneralisations are expected to be applied elsewhere. TOURISM AND ENVIRONMENT Environment has various meanings for tourism. In its broadest sense, the environment includes all natural and cultural elements as in OECD's (1981) definition to encompass the natural, built and cultural aspects. This holistic approach is encouraged in understanding the potential impacts arising from tourism. A narrower meaning of environment is the natural and built environment as used by Cohen (1978) and Inskeep (1991: 339). Environment can also be restricted to the natural or physical environment, in order to distinguish it from the economic and social aspects of tourism, as used by tourism researchers (e.g. Mathieson and Wall, 1982; Pearce, 1989). This approach is used predominantly in this volume. Various relationships between tourism and the physical aspects ofthe coast are discussed. There are basic relationships between environment and tourism. Tourism is environmentally dependent and the environment is vulnerable to the impact of tourism.…

Buch. Condición: Neu. Neuware - For 35 years, the critical and creative writings of Robert E. Butts have been a notable and welcome part of European and North American philosophy. A few years ago, James Robert Brown and Jiirgen Mittelstrass feted Professor Butts with a volume entitled An Intimate Relation (Boston Studies vol. 116, 1989), essays by twenty-six philosophers and historians of the sciences. And that joining of philosophers and historians was impressive evidence of the 'intimate relation' between historical illumination and philosophical understanding which is characteristic of Butts throughout his work. Not alone, Butts has been, and is, one of this generation's most incisive thinkers, devoted to responsible textual scholarship and equally responsible imaginative interpretation. Brown and Mittelstrass said that 'throughout his writings, science, its philosophy, and its history have been treated as a seamless web', and I would add only that philosophy per se is a part of the web too. Here in this book before us are the results, a lovely collection from the work of Robert Butts, who is for so many of his colleagues, students and readers, Mr. HPS, the model philosophical historian and historical philosopher of the sciences.

Buch. Condición: Neu. Neuware - Business Ethics: Japan and the Global Economy presents a multicultural perspective of global business ethics with special emphasis on Japanese viewpoints. In contrast to the typical business ethics book written primarily from the viewpoint of Western culture and economy, the majority of the work is by Asian scholars, providing an historical overview of the religious, scientific and cultural phenomena which converged to create modern Japanese business ethics. Perspectives from socioeconomics, sociology, social contract and applied business ethics contribute to the analysis of moral issues. A new Japanese approach to moral science, Moralogy, is introduced and its implications for phenomena such as the Keiretsu system are explored. Concurrently, prominent Western ethicists explore the role of moral language and the implications of Kantian ethics and contractarian approaches for developing universal moral standards. Because Japan is an economic superpower, it is critical to understand the hidden economic culture, work ethic, and way of thinking in business. We must realize these are the results of an integration of historical factors, such as Shintoism, Buddhism, Confuctianism and modern Western science and technology. Business Ethics: Japan and the Global Economy provides philosophical and anthropological analyses of the Japanese economic mind, departing from previous stereotyped approaches. Theoretical discussions based upon social contract theory are presented in order to build ethical norms with cross-cultural activity for multinational economic activities. From such a universal stance, practical proposals are presented to transnationalize the Keiretsu system and other Japanese economic institutions.…

Buch. Condición: Neu. Neuware - The hybridoma technique for producing monoclonal antibodies developed by Drs. Kohler and Millstein in 1975 revolutionized the field of tumor immunology. It is now clear that there are antigens associated with or restricted to human neoplasms that have biologic significance. Monoclonal antibodies have already been demonstrated to have great immunodiagnostic value, and it is anticipated that they will become a component of our therapeutic armamentarium. Most investigators in the field, however, feel the true potential of monoclonal antibodies in cancer therapy remains to be determined. Clearly the most encouraging results have been witnessed in the treatment of hematologic malignancies. This volume of Cancer Treatment and Research explores the current state of the art of immunoconjugate therapy of hematologic malignancies. The first chapter, authored by Drs. Rosen and Kuzel, reviews the current status of radioimmunotherapy of lymphoma. Results of clinical investigations utilizing radiolabeled immunoconjugates in B-cell lymphomas, T-cell lym phomas, and Hodgkin's disease are discussed. In addition, obstacles to effective antibody therapy are highlighted and toxicities are summarized. Chapter 2, written by Drs. Sgouros and Scheinberg, critiques the treat ment of leukemia with radiolabeled monoclonal antibodies. In this chapter, the unique features of leukemia that make it particularly suitable for radio immunotherapy are discussed, an overview of selected clinical trials is presented, and a treatment planning approach to radioimmunotherapy in corporating biologic and physical parameters is reviewed.…

Buch. Condición: Neu. Neuware - 1. A. HOWELL School ofChemical Engineering, University ofBath, Claverton Down, Bath, UK, BA2 7AY 1.1 WHAT IS A MEMBRANE PROCESS Every day over 20 million litres of brackish water are pumped out of the ground near Jeddah in Saudi Arabia and passed through thin sheets of cellulose acetate known as reverse osmosis membranes before being used as part of the city's water supply. In St Maurice les Chateauneuf, France three million litres a day of ground water are ultrafiltered to supply the city and on test sites in Australia settled sewage is being disinfected by being passed through microfiltration membranes. Many of the foods we eat and beverages we drink have used membranes during their processing. Orange juice can be concentrated by membranes to make a concentrate which retains more of the flavour than does evaporation. Milk can be concentrated slightly by means of a membrane before making a cheese in a process which produces no whey. Gases rising from the ground in a waste tip can be piped away and the carbon dioxide separated from the methane by a membrane process allowing the methane then to be used as a fuel, simultaneously saving energy and reducing the greenhouse effect since methane is more effective as a greenhouse gas than carbon dioxide.…

Taschenbuch. Condición: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -Combinatorial group theory is a loosely defined subject, with close connections to topology and logic. With surprising frequency, problems in a wide variety of disciplines, including differential equations, automorphic functions and geometry, have been distilled into explicit questions about groups, typically of the following kind: Are the groups in a given class finite (e.g., the Burnside problem) Finitely generated Finitely presented What are the conjugates of a given element in a given group What are the subgroups of that group Is there an algorithm for deciding for every pair of groups in a given class whether they are isomorphic or not The objective of combinatorial group theory is the systematic development of algebraic techniques to settle such questions. In view of the scope of the subject and the extraordinary variety of groups involved, it is not surprising that no really general theory exists. These notes, bridging the very beginning of the theory to new results and developments, are devoted to a number of topics in combinatorial group theory and serve as an introduction to the subject on the graduate level. 170 pp. Englisch.…
