Buch. Condizione: Neu. Neuware -I With the immense success of modem science it has generally become accepted that the only way to acquire knowledge is by the use of the method uniformly practiced by working scientists. Consequently, the credibility of the claims of religion, which seem to be based on belief in revelation, tradition, authority and the like, have been considerably shaken. In the face of the serious threat provided by the ascendancy of modem scientific method ology, religious thinkers have adopted various defensive attitudes. Some have retreated into an extreme position where Theism is completely safe from any attack on it by the use of empirical methods of inquiry, maintaining that contrary to appearances, religion makes no factual claims whatsoever. To be religious, they say, is to subscribe to a certain value system; it is to adopt a set of practices and a given attitude to the meaning and purpose of life without making any assertions about this or that empirical feature of the universe. Others wishing to remain more faithful to what religion traditionally meant throughout the ages, agree that Theism does make factual claims but that these are so radically different from the kind of claims made by science that it is only right that they should be established by a separate method on its own. In matters of faith reliance on widely entrenched tradition and sacred authority is not objectionable according to some.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 212 pp. Englisch.

Buch. Condizione: Neu. Neuware -This book consists of three parts, rather different in level and purpose: The first part was originally written for quantum chemists. It describes the correspondence, due to Frobenius, between linear representations and charac ters. This is a fundamental result, of constant use in mathematics as well as in quantum chemistry or physics. I have tried to give proofs as elementary as possible, using only the definition of a group and the rudiments of linear algebra. The examples (Chapter 5) have been chosen from those useful to chemists. The second part is a course given in 1966 to second-year students of I'Ecoie Normale. It completes the first on the following points: (a) degrees of representations and integrality properties of characters (Chapter 6); (b) induced representations, theorems of Artin and Brauer, and applications (Chapters 7-11); (c) rationality questions (Chapters 12 and 13). The methods used are those of linear algebra (in a wider sense than in the first part): group algebras, modules, noncommutative tensor products, semisimple algebras. The third part is an introduction to Brauer theory: passage from characteristic 0 to characteristic p (and conversely). I have freely used the language of abelian categories (projective modules, Grothendieck groups), which is well suited to this sort of question. The principal results are: (a) The fact that the decomposition homomorphism is surjective: all irreducible representations in characteristic p can be lifted 'virtually' (i.e., in a suitable Grothendieck group) to characteristic O.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 188 pp. Englisch.

Taschenbuch. Condizione: Neu. Neuware - This book is the result of lectures which I gave dur ing the academic year 1972-73 to third-year students a~ Aarhus University in Denmark. The purpose of the book, as of the lectures, is to survey some of the main themes in the modern theory of stochastic processes. In my previous book Probability: ! survey of the mathe matical theory I gave a short overview of 'classical' proba bility mathematics, concentrating especially on sums of inde pendent random variables. I did not discuss specific appli cations of the theory; I did strive for a spirit friendly to application by coming to grips as fast as I could with the major problems and techniques and by avoiding too high levels of abstraction and completeness. At the same time, I tried to make the proofs both rigorous and motivated and to show how certain results have evolved rather than just presenting them in polished final form. The same remarks apply to this book, at least as a statement of intentions, and it can serve as a sequel to the earlier one continuing the story in the same style and spirit. The contents of the present book fall roughly into two parts. The first deals mostly with stationary processes, which provide the mathematics for describing phenomena in a steady state overall but subject to random fluctuations. Chapter 4 is the heart of this part.

Buch. Condizione: Neu. Neuware - Philosophers writing on the subject of human action have found it tempting to introduce their subject by raising Wittgenstein's question, 'What is left over if you subtract the fact that my arm goes up from the fact that I raise my arm ' The presumption is that something of particular interest is involved in an action of raising an arm that is not present in a mere bodily movement, and the philosopher's task is to specify just what this is. Unfortunately, such an approach does not take us very far, since a person could properly be said to raise his (or her) arm while asleep or hypnotized even though he (or she) would not be performing an action in the sense of 'action' with which philosophers are particularly concerned. To avoid this kind of difficulty I shall approach the subject of human action is a more academic way: I shall expound some important rival theories of human action, and introduce the relevant issues by commenting critically on those theories. One of the issues I eventually introduce is a metaphysical one. A theory of action makes sense, I contend, only on the assumption that there are such 'things' as actions (or events). After considering some key arguments bearing on the issue I conclude that, as matters currently stand in philosophy, a metaphysically noncommittal attitude toward actions and events seems justified.

Buch. Condizione: Neu. Neuware - The cornerstone of the radical program of positivism was the separation of science from metaphysics. In the good old days, the solution to this demarca tion problem was seen as a way of separating sheep from goats - ~ynthetic or analytic propositions, which were candidates for truth or falsity, either on empirical or formal grounds, on the one hand; and, on the other hand, those deceptive propositions which appeared to be truth claims, but were instead either meaningless, or nonsensical, or poetical, or merely expressive - i.e. without proper cognitive content and hence not verifiable or falsifiable. In the last half century, analytic philosophy of science, linguistic analysis and logic have formulated and reformulated and reformulated again the distinction be tween science and metaphysics. The outcome was unexpected: metaphysics rather than retreating from the scene, shriveling up, dissolving, has instead re emerged as an acknowledged, even if problematic component of scientific theorizing. This has made some philosophers of science happy, others miserable. For Morris Lazerowitz, it should serve as evidence for his thesis that the sort of philosophical assertions which metaphysics makes about the nature of things are not simply radically undecidable, but persist because they express a deeper and unconscious function in the mental life of philosophers (and presumably, of those scientists who find it necessary to be philosophical in this way, whether self-consciously or tacitly).

Buch. Condizione: Neu. Neuware - This book grew out of previously published papers of mine composed over a period of years; they have been reworked (sometimes beyond recognition) so as to form a reasonably coherent whole. Part One treats of informative inference. I argue (Chapter 2) that the traditional principle of induction in its clearest formulation (that laws are confirmed by their positive cases) is clearly false. Other formulations in terms of the 'uniformity of nature' or the 'resemblance of the future to the past' seem to me hopelessly unclear. From a Bayesian point of view, 'learning from experience' goes by conditionalization (Bayes' rule). The traditional stum bling block for Bayesians has been to fmd objective probability inputs to conditionalize upon. Subjective Bayesians allow any probability inputs that do not violate the usual axioms of probability. Many subjectivists grant that this liberality seems prodigal but own themselves unable to think of additional constraints that might plausibly be imposed. To be sure, if we could agree on the correct probabilistic representation of 'ignorance' (or absence of pertinent data), then all probabilities obtained by applying Bayes' rule to an 'informationless' prior would be objective. But familiar contra dictions, like the Bertrand paradox, are thought to vitiate all attempts to objectify 'ignorance'. BuUding on the earlier work of Sir Harold Jeffreys, E. T. Jaynes, and the more recent work ofG. E. P. Box and G. E. Tiao, I have elected to bite this bullet. In Chapter 3, I develop and defend an objectivist Bayesian approach.

Buch. Condizione: Neu. Neuware -With this third edition of Nelson Goodman's The Structure of Appear ance, we are pleased to make available once more one of the most in fluential and important works in the philosophy of our times. Professor Geoffrey Hellman's introduction gives a sustained analysis and appreciation of the major themes and the thrust of the book, as well as an account of the ways in which many of Goodman's problems and projects have been picked up and developed by others. Hellman also suggests how The Structure of Appearance introduces issues which Goodman later continues in his essays and in the Languages of Art. There remains the task of understanding Good man's project as a whole; to see the deep continuities of his thought, as it ranges from logic to epistemology, to science and art; to see it therefore as a complex yet coherent theory of human cognition and practice. What we can only hope to suggest, in this note, is the b. road Significance of Goodman's apparently technical work for philosophers, scientists and humanists. One may say of Nelson Goodman that his bite is worse than his bark. Behind what appears as a cool and methodical analysis of the conditions of the construction of systems, there lurks a radical and disturbing thesis: that the world is, in itself, no more one way than another, nor are we. It depends on the ways in which we take it, and on what we do.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 348 pp. Englisch.

Taschenbuch. Condizione: Neu. Neuware -Dieses Buch ist für Psychologen, Psychiater, Kindertherapeuten, HeiI pädagogen, Sozialarbeiter, Lehrer und all diejenigen geschrieben, die Aufgaben der erzieherischen AusbiIdung übemommen haben. Ich habe mich bemüht, die Trainingsmethode samt der Vorbereitungs arbeit so darzustellen, daS sie aus dem Buch erlembar ist. Das ist sie natürlich nur für den, der ausreichend Erfahrung in diesem Bereich mitbringt. So einfach die Methode im Ansatz auch ist, zu ihrer Hand habung gehört ein difierenziertes Verhaltensmuster, das nur im üben unter Supervision oder unter anderen Formen der Rüekmeldung erwor ben werden kann. Man wird in dem Buch ein ambivalentes Verhältnis zur Theorie finden. Einerseits erscheint es mir notwendig, Erfahrungen vor dem Hinter grund einer Theorie zu reflektieren und ein System zu biIden, in dem versueht wird, die verschiedenen Handlungsschritte in einen logischen Zusammenhang zu bringen. Andererseits begegne ich häufig dem Feh ler, daS dort theoretisiert wird, wo man handeln solIte, oder daS theo retisehe Vorstellungen zu Scheuklappen werden, die das Wahmehmen altemativer Lösungen verhindem. Wo theoretische überlegungen nicht auf Erfahrungen aufbauen, wo die Reihenfolge 'zuerst beobachten, dann theoretisch reflektieren' nicht eingehalten wird, könnte ich nicht mehr mitmachen. So habe ich das, was getan werden soll, in den Vor dergrund gesteIlt und die theoretischen Reflexionen kurz gehalten. Diese sollen den Gegenstand einer weiteren Arbeit biIden.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 252 pp. Deutsch.

GegenUber dem unter dem Titel 'Grundlagen der Wahrscheinlichkeitstheorie' im Bochurner Studienverlag Brockmeyer 1975 erschienenen Vorlesungsskrip tum ist die jetzige Fassung methodisch liberarbeitet und fast urn das Doppelte erweitert worden. In dem Bemlihen, dem jeweiligen Kenntnisstand der Studenten entgegen zukommen, wurden die Vorlesungen mit unterschiedlich gesetzten Schwer punk ten abgehalten. Auf diese Weise entstanden im Laufe der Zeit verschiedene Manuskripte, bei deren Abfassung sich der erste Autor auf Vorlesungen seiner verehrten Lehrer K. Krickeberg (Paris) und J. Pfanzagl (Keln) stlitzen konnte, was insbesondere im flinften Kapitel zum Ausdruck kommt. Die Abfassung von Abschnitt 3.1 sowie die sonstigen mehr maBtheoretischen Teile im achten Kapitel wurden wesentlich durch Diskussionen mit F. Tops~e (Kopenhagen) beeinfluBt. Kapitel I wurde gepr~gt durch Vorlesungsskripten zur MaBtheorie unseres frliheren Bochumer Kollegen und Lehrers H.G. Kellerer (Mlinchen). Den Herren Dr. W. Adamski, Dipl.-Math. W. Hummitzsch und Dipl.-Math. J. Strobel sind wir zu groBem Dank verpflichtet. Sie haben wertvolle Anregungen beigesteuert und uns beim Lesen der Korrekturen untcr stiitzt. Herr Hummitzsch hat auBcrdem den Zcichenindex und das Namen und Sachregister angefertigt.

This item is printed on demand - it takes 3-4 days longer - Neuware -For two weeks in August, 1975 more than 140 mathematicians and other scientists gathered at the Universite de Sherbrooke. The occasion was the 15th Biennial Seminar of the Canadian Mathematical Congress, entitled Mathematics and the Life Sciences. Participants in this inter disciplinary gathering included researchers and graduate students in mathematics, seven different areas of biological science, physics, chemistry and medical science. Geographically, those present came from the United States and the United Kingdom as well as from academic departments and government agencies scattered across Canada. In choosing this particular interdisciplinary topic the programme committee had two chief objectives. These were to promote Canadian research in mathematical problems of the life sciences, and to encourage co-operation and exchanges between mathematical scientists' biologists and medical re searchers. To accomplish these objective the committee assembled a stim ulating programme of lectures and talks. Six principal lecturers each delivered a series of five one-hour lectures in which various aspects of the interaction between mathematics and the life sciences were considered. In addition researchers working in the areas of health, population biology, physiology and development biology and disease processes were invited to give more than 25 hours of complementary talks. 400 pp. Englisch.

Taschenbuch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -This book really ought to be read on vacation, just for enjoyment. Granted, cancer is, literally, a deadly serious matter, and cancer research is primarily a part of medicine with Hippocrates in its back ground. Yet, cancer research is also natural science, and as such it yields the joys and sorrows of any science. The cancer problem is also a brain teaser, a challenge for the curious. This introductory report on experimental cancer research is there fore directed to curious students of many disciplines: naturally to medical students, but also to chemists and physicists who have an interest in biological phenomena; biology students will surely en counter pr9blems peculiar to their field in what is supposedly a medi cal one. We have attempted to write without assumptions to a certain degree, for a chemist is essentially in over his head in medicine, and a physician has only the slightest idea of the chemical problems im portant in cancer research. We had no intention of giving a complete view of the field, and from the large number of different lines of development we have chosen only a few. Chemotherapy, as an ex ample, has been treated quite cursorily, along with RNA tumor viruses, although it is possible that just these subjects are especially important for human tumors. Tumor induction via radiation could only be mentioned in passing, in spite of its great practical significance; similarly the role of hormones was only intimated. 312 pp. Englisch.

The Symposium took place in Sandbjerg Manor House in Southern Jutland May 10-14, 1976. The purpose of the symposium was to reflect contemporary research on the mechanisms of biological evolu tion. The arrangement of the symposium was possible only with the assis tance and work of many other people. Professor Ole Barndorff-Nielsen took an active part in the planning and arrangement of the symposium. Our gratitude is also due to Ellen Christensen, Jens Ole Frier, Arno Jensen, Preben Jensen and Anne Nissen, all of whom took care of the practical arrangements at the symposium. The publication was prepared with the assistance of Arno Jensen, Preben Jensen, Verner Blak Nielsen and Kirsten Svendsen. The Symposium was financed by grants from The Danish Natural Science Research Council, The Danish Atomic Energy Commission and The University of Aarhus. Aarhus, June 1977 Freddy B.

This is not only the result of the 'publish or perish' law, but also - let us hope mainly - the result of the increasing amount of true scientific information discovered. Even in a single scientific field too many papers are to be preselected according to the individual interest and to be looked through in order to see what they are reporting on. [And of course they are too many in these preselected to be read and studied in detai I. At the present nobody wi I I help us with this last link of what is called the information chain.
