Taschenbuch. Condition: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -The aim of this paper is to show that the theory of jet bundles supplies the appropriate setting for the study of Backlund trans formations. These transformations are used to solve certain partial differential equations, particularly non-linear evolution equations. Of course jets have been employed for some time in the theory of partial differential equations, but so far little use has been made of them in applications. In the meanwhile, substantial progress has been made in the study of non-linear evolution equations. This work has been encouraged by the dis covery of remarkable properties of some such equations, for example the existence of soliton solutions and of infinite se quences of conservation laws. Among the techniques devised to deal with these equations are the inverse scattering method and the Backlund transformation. In our opinion the jet bundle formulation offers a unifying geometrical framework for under standing the properties of non-linear evolution equations and the techniques used to deal with them, although we do not consider all of these properties and techniques here. The relevance of the theory of jet bundles lS that it legitimates the practice of regarding the partial derivatives of field variables as independent quantities. Since Backlund trans formations require from the outset manipulation of these partial derivatives, and repeated shifts of point of view about which variables are dependent on which, this geometrical setting clari fies and simplifies the concepts involved, and offers the prospect of bringing coherence to a variety of disparate results. 144 pp. Englisch.

Taschenbuch. Condition: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -Marx Wartofsky has been working for many years within an unusual confluence of philosophical problems. He brings to these intersecting problems his comprehensive intelligence, at once imaginative and rigorous, analytic and historical. He is a philosopher's philosopher, but also Everyman's. Wartofsky is philosopher of the natural and the social sciences, of perception, esthetics and the creative arts, of the 18th century French and the 19th century Germans, of politics and morality, ofthe methods and morals of medicine, and it is plain, of all human existence. To a colleague, he seems Jack-of-all-philosophical-trades, and master of them too. The reader soon will learn that Wartofsky is a genial, lucid and relaxed philosophical companion, deeply serious but without noticeable anxiety. I need not highlight these selected epistemological papers gathered as, and about, Models, since Wartofsky's own introductory remarks are helpful and stimulating in that respect. I need only, after 21 years of friendship and collaboration with him, warn the reader to beware of how profound and provocative these papers will show themselves to be beneath their good-humored and swiftly-flowing surface. And I must publicly note the pleasure with which I welcome Marx Wartofsky's volume to our Boston Studies. Boston University R.S.C.

Taschenbuch. Condition: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -Vegetation dynamics is an important subject. A knowledge and under standing of it is central to the science of vegetation management-in grassland, range and nature reserve management, and in aspects of wildlife management, forestry and agricultural crop production. It is also a large and diffuse subject. In a small book such as this I had to be highly selective, and could not do equal justice to all aspects. I have had therefore to condense many examples, and more regrettably, many arguments. While I have tried to present a broad selection of topics and examples, the content inevitably reflects my own special interests and experience. The study of vegetation and its dynamics does not lend itselfto neat and tidy divisions, and the way of allotting material into different chapters here is arbitrary. I have used Chapter I to introduce a number of ideas, beginning with the nature of vegetation in space, then passing to an introduction to the nature of changes in vegetation with time, in particular those generally known as successions. The book also contains a number of asides to the text's central arguments; I hope the reader finds these interesting rather than disconcerting. 84 pp. Englisch.

Taschenbuch. Condition: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -The bibliography includes papers in al I fields of photosynthesis research - from stu dies of model biochemical and biophysical systems of the photosynthesis mechanism to primary production studied by the so-cal led growth analysis. In addition to papers devoted entirely'to photosynthesis, papers on other topics are included if they con tain data on photosynthetic activity, photorespiration, chloroplast structure, chlo rophyll and carotenoid synthesis and destruction, etc. ' or if they contain valuable methodological information (measurement of selected environmental factors, leaf area, etc. ). In many branches it has been very difficult to define the I imits of interest for photosynthesis researchers. This problem has arisen e. g. in topics deal ing with the transport of gases, where - in addition to the papers on CO transfer - some pa 2 pers on water vapour transfer are included, these being of general application. On the other hand, many papers deal ing with the anatomy and physiology of stomata have been omitted, if the aspect of carbon dioxide or water vapour 'exchange has not been discussed. This volume contains references to papers publiphed in the year 1974, and, simi larty to Vol. 4, also addenda inc~uding references publ ished in the preceding period (i. e. 1966 - 1973). The numbers of these additional references. are label led with an asterisk in the list of refe. 184 pp. Englisch.

Taschenbuch. Condition: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -The contact between the human blood and foreign technical apparatus (circulatory) and respiratory assist devices, arti ficial kidneys) leads to changes in the plasmatic and cel lular components of the blood, which have often only been taken as signs of gross but passive blood destruction. There is much evidence to support this notion in parts (mechanical cellolysis of erythrocytes and thrombocytes), however, these changes have to be seen in a broader bio logical context as an organ-specific reaction of the blood. It is an unjustified oversimplification to simply treat the blood as transport organ for respiratory gases (02 and CO ) and metabolites. The blood is rather also an organ 2 system for specific and unspecific defense mechanisms, di rected against the hazards of mechanical, microbiological and toxicological risks posed to multicellular macro-orga nisms in an environment in which trauma and other distur bances of the physical integrity are common. The two defense systems of the blood are based on humural and cellular constituents; the latter have to be considered as 'excitable cells', capable of responding in a predictable and automatic fashion to adequate stimuli. The response of the cellular constituents in controlled and coordinated by chemical mediators. The immunological research of the last century has distinguished two separate defense systems of the blood: I. The highly specific defense system (immune system sen sustrictori) which is phylogenetically new and is ontogenetically learned. 424 pp. Englisch.

Taschenbuch. Condition: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -The islands of the Pacific and East Indies made an enormous and fateful impact on the minds of Charles Darwin and Alfred Wallace, the fathers of modem evolutionary theory. Since then island floras and faunas have continued to playa central role in the development of evolutionary, and more recently ecological thought. For much ofthis century island ecology was a descriptive science and a wealth of information has been amassed on patterns of species distributions, on the composition of island floras and faunas, on the classification of islands into types such as oceanic and continental, on the taxonomic description of insular species and sub-species and on the adaptations, often bizarre, of island creatures. However, biologists are not satisfied for long with the mere collection of data and the description of patterns, but seek unifying theories. Island ecology was transformed into a predictive science by the publication, in 1967, of MacArthur and Wilson's Theory of Island Biogeography. This, perhaps the most influential book written on island ecology, has been the stimulus for a generation of theoretical ecologists and gifted field workers. The books listed below in the bibliography will indicate to the reader the vast scope of island ecology and the changes in approach that have taken place over the years. 80 pp. Englisch.

Buch. Condition: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -With one exception, all of the papers in this volume were originally presented at a conference held in April, 1978, at The Ohio State University. The excep tion is the paper by Wilfrid Sellars, which is a revised version of a paper he originally published in the Journal of Philosophy, 1973. However, the present version of Sellars' paper is so thoroughly changed from its original, that it is now virtually a new paper. None of the other nine papers has been published previously. The bibliography, prepared by Nancy Kelsik, is very extensive and it is tempting to think that it is complete. But I believe that virtual com pleteness is more likely to prove correct. The conference was made possible by grants from the College of Human ities and the Graduate School, Ohio State University, as well as by a grant from the Philosophy Department. On behalf of the contributors, I want to thank these institutions for their support. I also want to thank Marshall Swain and Robert Turnbu~l for early help and encouragement; Bette Hellinger for assistance in setting up the confer ence; and Mary Raines and Virginia Foster for considerable aid in the pre paration of papers and many other conference matters. The friendly advice of the late James Cornman was also importantly helpful. April,1979 GEORGE S.

This item is printed on demand - it takes 3-4 days longer - Neuware -This varied and impressive volume is a record of the major presentations at the NATO Advanced Research Workshop on the 'Development of Sex Differences and Similarities in Behavior' held at Château de Bonas, Gers, France, July 14-18, 1992. Although aspects of sex differences in human and animal behavior have been recently extensively explored both academically and in popularized accounts, the present work shows that the complex interplay between the various biological, political, psychological and sociological factors that account for sex differences has always been, and will continue to be, a source of infinite fascination and confusion to humans. The book contains presentations by a powerful mixture of eminent scientists from the relevant biological and social sciences areas, any ethnocentric tendencies being tempered by the wide mix of nationalities. Current information is placed in an evolutionary and genetic context and includes material from anatomical, endocrinological and behavioral studies of animal behavior and from the human cognitive sciences. The Development of Sex Differences and Similarities in Behavior is accessible to a spectrum of readers, from university undergraduates to experienced professionals. 224 pp. Englisch.

Taschenbuch. Condition: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -1. 1. Short History of Solar Radio Astronomy Since its birth in the forties of our century, solar radio astronomy has grown into an extensive scientific branch comprising a number of quite different topics covering technical sciences, astrophysics, plasma physics, solar-terrestrial physics, and other disciplines. Historically, the story of radio astronomy goes back to the times of James Clerk Maxwell, whose well known phenomenological electromagnetic field equations have become the basis of present-time radio physics. As a direct consequence of these equations, Maxwell was able to prognosticate the existence of radio waves which fifteen years later were experimentally detected by the famous work of Heinrich Hertz (1887/88). However, all attempts to detect radio waves from cosmic objects failed until 1932, which was mainly due to the early stage of development of receiving techniques and the as yet missing knowledge of the existence of a screening ionosphere (which was detected in 1925). Therefore, famous inventors like Thomas Edison and A. E. Kennelly, as well as Sir Oliver Lodge, were unsuccessful in receiving any radio emission from the Sun or other extraterrestrial sources. Another hindering point was that nobody could a priori expect that solar radio emission should have something to do with solar activity so that unfortunately by chance some experiments were carried out just at periods of low solar activity. This was also why Karl Guthe Jansky at the birth of radio astronomy detected galactic radio waves but no emission from the Sun. 356 pp. Englisch.

THE MACROMOLECULAR ELECTROSTATIC EFFECT IN BIOCHEMICAL ~EACTIVITY OF THE NUCLEIC ACIDS. BERNARD PULUIAN Institut de BioLogie Physico-Chimique, Laboratoire de Biochimie Theorique, aSSOCle au C. N. R. S. , 13, rue P. et M. Curie, Paris 75005, France. 1. INTRODUCTION The roLe of the macromoLecuLe and of its overaLL structure upon the reactivity of its reaction site(s) represents one of the fundamentaL probLems in the theory of cataLysis. The most impressive and most fre quentLy considered exampLes occur in the fieLd of proteins where the probLem generaLLy consists of accounting for the enhancement of the reaction rate at the active site or at the coenzyme with respect to modeL systems, devoid of the macromoLecuLar superstructure. Different effects have been considered as possibLy responsibLe for the infLuence of the macromoLecuLe on such LocaLized-site reactions. I do not have the time to summarize or discuss them here. 404 pp. Englisch.

Buch. Condition: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -The presence of nonconvexities does severe damage to conventional theories of the firm and of the individual. The essential contribution of location theory, however, is in a world in which there are such nonconvexities. If resources are distributed evenly and the usual convexity assumptions made, then economic activity would be distributed evenly; there would be no concentration of pro duction. Thus the statement that is usually made, that the standard results carry over to a world in which there is spatial choice, is too weak and fails to capture the essence oflocation theory. Nevertheless, we must also concede that, while the introduction of the spatial dimension is interesting and fruitful when (perhaps only when) there are non convexities, space should not be thought of as a panacea whereby problems those associated with economies of scale, for example -can be made to disap pear. There is no guarantee, for example, that production units will be operated in convex regions of their total cost curves, even if they are constrained to oper ate in a 'space economy'. These considerations led to the conclusion that the role of spatial choice and the determinants of such choice would be best analysed by case study. This book is one such study. It is based on my doctoral dissertation at the University of Cambridge, fmanced by a grant from the Social Science Research Council. 228 pp. Englisch.

Buch. Condition: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -The most general goal of this book is to propose and illustrate a program of research in word semantics that combines some of the methodology and results in linguistic semantics, primarily that of the generative semantics school, with the rigorously formalized syntactic and semantic framework for the analysis of natural languages developed by Richard Montague and his associates, a framework in which truth and denotation with respect to a model are taken as the fundamental semantic notions. I hope to show, both from the linguist's and the philosopher's point of view, not only why this synthesis can be undertaken but also why it will be useful to pursue it. On the one hand, the linguists' decompositions of word meanings into more primitive parts are by themselves inherently incomplete, in that they deal only in distinctions in meaning without providing an account of what mean ings really are. Not only can these analyses be made complete by a model theoretic semantics, but also such an account of these analyses renders them more exact and more readily testable than they could ever be otherwise. 448 pp. Englisch.
