Taschenbuch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -Since the first edition there has been a great demand for this book. It has been revised to include up-to-date and new entries covering recent additions to the availa ble drugs. As well there are now sections on clinical situations, or types of patient, presenting especial problems. The authors hope this new material will enhance the effectiveness of the book as a guide to this rapidly advancing and changing therapeutic situation. A.P.B. J.A.G. J.McC.M. July, 1978 v Contents I.

Taschenbuch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -The organization of this Symposium had its beginnings at the International Astronomical Union General Assembly in Grenoble in 1976. The initial 'rounding up' of the Scienti fic Organizing Committee was begun by Drs. Snow and Swings; most of us who became the eventual organizing committee met a few times during the Assembly and formulated the essential outlines of the meeting. Extensive correspondence with all the committee subsequently established the program. The idea was to bring together both observers and theoreticians to discuss the stellar winds and mass loss rates and their effects on evolutions of O-type stars. On the observational side, there are now spectroscopic data from the far UV to the near IR regions concerning the stellar winds. There is also information about the free-free emission in the wind from the IR and radio portions of the spectrum. Fortunately, these different detection methods give more or less the same mass loss rate for the one star, s Pup' which has been observed at all wavelengths. One of the intents of the first three sessions of this Symposium is to outline the eXisting data on mass loss rates as it per tains to the O-type stars. 524 pp. Englisch.…

Taschenbuch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -THE ECOLOGICAL SURVEY on which this book is based began to be planned in 1942, and since 1945 has been mainly centred upon Oxford University's estate at Wytham Woods, where a rich series of habitats from open ground and limestone to woodland with many springs and marshes interspersed occupies a hill set in riverine surroundings. Here biological research workers from the University have accumulated a considerable body of knowledge, some of which I have arranged in a general setting that allows one to comprehend some of the inter-related parts of the whole system. It is also intended to provide a framework for understanding animal communities elsewhere. The ecological inquirer is, more than most scien tific people, apt to fmd himself lost in a large labyrinth of interrelations and variables. The dictionary defmes a labyrinth as 'an intricate structure of inter communicating passages, through which it is difficult to fmd one's way without a clue'. This could equally be a figurative description of plant and animal communi ties. The present book seeks to provide a plan of construction of the labyrinth and a few new clues that may help the inquirer to know where he is on the gene ral ecological map. In presenting this blue-print of animal communities I have avoided giving long lists of species such as the botanist, with his smaller kingdom, can handle fairly well. 492 pp. Englisch.…

This item is printed on demand - it takes 3-4 days longer - Neuware -The aim of this series is to inform both professional philosophers and a larger readership (of social and natural scientists, methodologists, mathematicians, students, teachers, publishers, etc. ) about what is going on, who's who, and who does what in contemporary philosophy and logic. PROFILES is designed to present the research activity and the results of already outstanding personalities and schools and of newly emerging ones in the various fields of philosophy and logic. There are many Festschrift volumes dedicated to various philosophers. There is the celebrated Library of Living Philosophers edited by P. A. Schilpp whose format influenced the present enterprise. Still they can only cover very little of the contemporary philosophical scene. Faced with a tremen dous expansion of philosophical information and with an almost frighten ing division of labor and increasing specialization we need systematic and regular ways of keeping track of what happens in the profession. PRO FILES is intended to perform such a function. Each volume is devoted to one or several philosophers whose views and results are presented and discussed. The profiled philosopher(s) will summarize and review his (their) own work in the main fields of signifi cant contribution. This work will be discussed and evaluated by invited contributors. Relevant historical and/or biographical data, an up-to-date bibliography with short abstracts of the most important works and, whenever possible, references to significant reviews and discussions will also be included. 276 pp. Englisch. …

Taschenbuch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -The goal of the present volume is to discuss the notion of a 'conceptual framework' or 'conceptual scheme', which has been dominating much work in the analysis and justification of knowledge in recent years. More specifi cally, this volume is designed to clarify the contrast between two competing approaches in the area of problems indicated by this notion: On the one hand, we have the conviction, underlying much present-day work in the philosophy of science, that the best we can hope for in the justifi cation of empirical knowledge is to reconstruct the conceptual means actually employed by science, and to develop suitable models for analyzing conceptual change involved in the progress of science. This view involves the assumption that we should stop taking foundational questions of epistemology seriously and discard once and for all the quest for uncontrovertible truth. The result ing program of justifying epistemic claims by subsequently describing patterns of inferentially connected concepts as they are at work in actual science is closely connected with the idea of naturalizing epistemology, with concep tual relativism, and with a pragmatic interpretation of knowledge. On the other hand, recent epistemology tends to claim that no subsequent reconstruction of actually employed conceptual frameworks is sufficient for providing epistemic justification for our beliefs about the world. This second claim tries to resist the naturalistic and pragmatic approach to epistemology and insists on taking the epistemological sceptic seriously. 336 pp. Englisch.…

Buch. Condizione: Neu. This item is printed on demand - Print on Demand Titel. Neuware -Three years ago the Reports on Astronomy were for the first time published in three separate parts whereby related astronomical topics were collected in one volume and each volume was kept to a size of no more than about 250 pages. The a~m was to facilitate a wider distribution of individual volumes among astronomers and other scientists interested in specific subjects of astronomy. The same system was adopted for the present volume A of the IAU Transactions which covers the activities in astronomical research from January 1976 to December 1978. The Commission Presidents were invited to restrict their reports, to present a selection of the most important developments in the field of astronomy covered by their Commission, and to avoid overlaps with other Commission reports. As a re sult of the restriction in the number of pages some Commissions presen.t a large, concentrated list of references with little discussion, whereas others review some of the most exciting recent research developments in their subject. The distribution of the Commission Reports into the three parts of volume XVII A is as follows: VOL. XVII A PART 1 commission 4. Ephemerides 5. Documentation 6. Astronomical Telegrams ' 7. Celestial Hechanics ' 9. Instruments and Techniques 14. Fundamental Spectroscopic Data ' 15. Physical Study of Cornets, Hinor Planets and Meteorites 16.

Neuware -While much has been gained from the traditional legal scholars' doctrinal mode of analysis of the takings issue, this volume is presented in the belief that contributions from scholars from the various schools of thought that comprise Law and Economics can complement the traditional doctrinal approach to law. As the discipline of Law and Economics continues to advance, it remains heterodox; there are several vantage points from which to describe and analyze the interrealtionships between law and economics. It is hoped that the analyses from the several vantage points provided here will complement the prodigous body of existing doctrinal, legal analysis of the takings issue and deepen the understanding of the jurisprudential questions and economic issues surrounding the takings issue. To this end, each contributor to this volume was selected as 'representative' of one of the schools of thought comprising Law and Economics. In addition, each contributor was provided with a collection of recent United States Supreme Court cases (those summarized in Chapter 1 of this book) along with President Regan's Executive Order: The sole charge to each contributor was to conduct a legal-economic analysis of the cases and the President's Executive Order from the vantage point of their respective school of thought.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 186 pp. Englisch.…

Buch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -The humanist treatises presented here are only peripheral to the history of logic, but I think historians of logic may read them with interest, if perhaps with irritation. In the early sixteenth century the humanists set about to demolish medieval logic based on syllogistic and disputation, and to replace it in the university curriculum with a 'rhetorical' logic based on the use of topics and persuasion. To a very large extent they succeeded. Although Aris totelian logic retained a vigorous life in the schools, it never again attained to the overwhelming primacy it had so long enjoyed in the northern universities. It has been the custom to take the arguments of the humanists at face value, and the word 'scholastic' has continued to have pejorative overtones. This is easy to understand, because until recently our knowledge of the high period of medieval logic has been slight, and the humanists' testimony as to its decadent state in the sixteenth century has, for the most part, been accepted uncritically. Within the past two decades important work on medieval logic has recovered the brilliant achievement of thirteenth and fourteenth century logicians, philosophers, and natural scientists. New studies are constantly appearing, and the logico-semantic system of the terminists has become fruitful territory not only for historians of logic but also for students of modern linguistics and semiotics. 266 pp. Englisch.…

Taschenbuch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -The twentieth century has witnessed a striking transformation in the understanding of the theories of mathematical physics. There has emerged clearly the idea that physical theories are significantly characterized by their abstract mathematical structure. This is in opposition to the tradi tional opinion that one should look to the specific applications of a theory in orrter to understand it. One might with reason now espouse the view that to understand the deeper character of a theory one must know its abstract structure and understand the significance of that structure, while to understand how a theory might be modified in light of its experimental inadequacies one must be intimately acquainted with how it is applied. Quantum theory itself has gone through a development this century which illustrates strikingly the shifting perspective. From a collection of intuitive physical manoeuvers under Bohr, through a formative stage in which the mathematical framework was bifurcated (between Schrodinger and Heisenberg) to an elegant culmination in von Neumann's Hilbert space formulation, the elementary theory moved, flanked even at this later stage by the ill-understood formalisms for the relativistic version and for the field-theoretic alternative; after that we have a gradual, but constant, elaboration of all these quantal theories as abstract mathematical structures (their point of departure being von Neumann's formalism) until at the present time theoretical work is heavily preoccupied with the manipulation of purely abstract structures. 492 pp. Englisch.…
