A second solution to this problem is to develop a scale for weighing the significance of the conflicting principles in a given case and for concluding which action should be adopted because it is supported by the weightier considerations in that case. Such a solution seems more realistic than the lexical ordering approach, but the development of such a scale is a problematic task. Still other, more complex solutions are possible. Which is the best solution to this problem of conflicting principles of bioethics We need a moral theory to answer that question. This is the first reason for concluding that the principles of bioethics are not the true foundations of justified judgment in bioethics. What is the problem of the unclear scope and implications of the principles of bioethics and how can an appeal to moral theory help deal with that problem The scope of a bioethical principle is the range of cases in which it applies. The implications of a bioethical principle are the conclusions to be derived from that principle in those cases in which it applies. It is clear from a review of the discussions in bioethics that there are major unclarities about the scope and implications of each of the principles. Consider, for example, the principle of autonomy.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 244 pp. Englisch.

Then one day, that they can't see the problem. perhaps you will find the final question. G. K. Chesterton. The Scandal of Father 'The Hermit Clad in Crane Feathers' in R. Brown 'The point of a Pin'. van Gulik's The Chinese Maze Murders. Growing specialization and diversification have brought a host of monographs and textbooks on increasingly specialized topics. However, the 'tree' of knowledge of mathematics and related fields does not grow only by putting forth new branches. It also happens, quite often in fact, that branches which were thought to be completely disparate are suddenly seen to be related. Further, the kind and level of sophistication of mathematics applied in various sciences has changed drastically in recent years: measure theory is used (non-trivially) in regional and theoretical economics; algebraic geometry interacts with physics; the Minkowsky lemma, coding theory and the structure of water meet one another in packing and covering theory; quantum fields, crystal defects and mathematical programming profit from homotopy theory; Lie algebras are relevant to filtering; and prediction and electrical engineering can use Stein spaces. And in addition to this there are such new emerging subdisciplines as 'experimental mathematics', 'CFD', 'completely integrable systems', 'chaos, synergetics and large-scale order', which are almost impossible to fit into the existing classification schemes. They draw upon widely different sections of mathematics.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 316 pp. Englisch.

Buch. Condizione: Neu. Neuware -This book explores the nature of factual inference in adjudication. The book should be useful to students of law in Continental Europe as well as to students of Anglo-American law. While a good many countries do not use the sorts of rules of evidence found in the Anglo-American legal tradition, their procedural systems nevertheless frequently use a variety of rules and principles to regulate and structure the acquisition, presentation, and evalu ation of evidence. In this sense, almost all legal systems have a law of proof. This book should also be useful to scholars in fields other than law. While the papers focus on inference in adjudication, they deal with a wide variety of issues that are important in disciplines such as the philosophy of science, statistics, and psychology. For example, there is extensive discussion of the role of generalizations and hypotheses in inference and of the significance of the fact that the actors who evaluate data also in some sense constitute the data that they evaluate. Furthermore, explanations of the manner in which some legal systems structure fact-finding processes may highlight features of inferential processes that have yet to be adequately tackled by scholars in fields other than law.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 362 pp. Englisch.

Buch. Condizione: Neu. Neuware -Suzanne Flynn and Wayne O'Neil Massachusetts Institute of Technology I. INTRODUCTION The theory of Universal Grammar (UG) as explicated e. g. in Chomsky, 1986, has led to explosive developments in the study of natural language as well as to significant advances in the study of first language (L I) acquisition. Most recently. the theory of UG has led to important theore tical and empirical advances in the field of adult second language (L2) acquisition as well. The principle impetus for this development can be traced to the work in linguistics which shifted the study 'from behavior or the products of behavior to states of the mind/brain that enter into behavior' (Chomksy. 1986:3). Grammars within this framework are conceived of as theoretical accounts of 'the state of the mind/brain of the person who knows a particular language' (Chomsky. 1986:3). Research within fields of language acquisition seeks to isolate and specify the properties of the underlying competence necessary for language learning. Full development of a theory of UG demands study and understanding of the nature of both the formal properties of language and of the language acquisition process itself. However. while there is a tradition of debate and dialogue established between theoretical linguistics and Ll acquisition research. relatively few connections have been made between linguistic theory and L2 acquisition research.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 460 pp. Englisch.

Buch. Condizione: Neu. Neuware -The general aim of this book is to provide an elementary exposition of some basic concepts in terms of which both classical and non-dassicallogirs may be studied and appraised. Although quantificational logic is dealt with briefly in the last chapter, the discussion is chiefly concemed with propo gjtional cakuli. Still, the subject, as it stands today, cannot br covered in one book of reasonable length. Rather than to try to include in the volume as much as possible, I have put emphasis on some selected topics. Even these could not be roverrd completely, but for each topic I have attempted to present a detailed and precise t'Xposition of several basic results including some which are non-trivial. The roots of some of the central ideas in the volume go back to J.Luka siewicz's seminar on mathematicallogiSpringer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 496 pp. Englisch.

Taschenbuch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -The present edition may be regarded as a descendant, much changed and greatly enlarged, of the late Dr A. D. Imms' Outlines of Entomology, first published in 1942. This went through three further editions without much change, but after the death of the original author a fifth, revised edition by Professor O. W. Richards and myself appeared in 1959 and a sixth in 1978. The book now appears in a considerably extended version in which I have tried to provide a more balanced introduction to the whole field of modern entomology by dealing with several aspects of the subject not discussed at all in previous editions. Thus, in addition to innumerable lesser changes in the sections on insect structure, function, development, classification and phylogeny, I have completely recast the earlier chapter on some important modes of life in insects. This now includes a far wider range of biological topics well exemplified by the insects and should, I hope, appeal not only to those already dedicated to entomology but also to others with more general biological interests. A completely new chapter on the biology of insect populations has also been added and may serve to indicate the debt which modern ecological theory owes to work on insect populations. It should hardly be necessary to apologize for introducing a certain amount of elementary mathematics into this account of a subject which is now among the most highly quantitative of biological disciplines. 420 pp. Englisch.

Taschenbuch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -This book concerns digital communication. Specifically, we treat the transport of bit streams from one geographical location to another over various physical media, such as wire pairs, coaxial cable, optical fiber, and radio waves. Further, we cover the mul tiplexing, multiple access, and synchronization issues relevant to constructing com munication networks that simultaneously transport bit streams from many users. The material in this book is thus directly relevant to the design of a multitude of digital communication systems, including for example local and metropolitan area data net works, voice and video telephony systems, the integrated services digital network (ISDN), computer communication systems, voiceband data modems, and satellite communication systems. We extract the common principles underlying these and other applications and present them in a unified framework. This book is intended for designers and would-be designers of digital communication systems. To limit the scope to manageable proportions we have had to be selective in the topics covered and in the depth of coverage. In the case of advanced information, coding, and detection theory, for example, we have not tried to duplicate the in-depth coverage of many advanced textbooks, but rather have tried to cover those aspects directly relevant to the design of digital communication systems. 732 pp. Englisch.

Buch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -A variety of nonlinear effects occur in a plasma. First, there are the wave steepening effects which can occur in any fluid in which the propagation speed depends upon the wave-amplitude. In a dispersive medium this can lead to classes of nonlinear waves which may have stationary solutions like solitons and shocks. Because the plasma also acts like an inherently nonlinear dielectric resonant interactions among waves lead to exchange of energy among them. Further, an electromagnetic wave interacting with a plasma may parametrically excite other waves in the plasma. A large-amplitude Langmuir wave undergoes a modulational instability which arises through local depressions in plasma density and the corresponding increases in the energy density of the wave electric field. Whereas a field collapse occurs in two and three dimensions, in a one-dimensional case, spatially localized stationary field structures called Langmuir solitons can result. Many other plasma waves like upper-hybrid waves, lower-hybrid waves etc. can also undergo a modulational instability and produce localized field structures. A new type of nonlinear effect comes into play when an electromagnetic wave propagating through a plasma is strong enough to drive the electrons to relativistic speeds. This leads to a propagation of an electromagnetic wave in a normally overdense plasma, and the coupling of the electromagnetic wave to a Langmuir wave in the plasma. The relativistic mass variation of the electrons moving in an intense electromagnetic wave can also lead to a modulational instability of the latter. 220 pp. Englisch.

Methods are required to account for and measure the quantity of mortgage equity arising from such favorable financing. Holders of mortgage backed securities face risks on both sides of interest rate movements. Should interest rates fall, debtors refinance. If interest rates rise, debtors do not refinance, and the holders of mortgage backed securities suffer capital losses. Hedging strategies are re quired. Mortgage warrants and option pricing mechanisms are discussed, and various equity unlocking mechanisms, such as collateralized mort gage obligations. 340 pp. Englisch.

This research was an outgrowth of the arctic IBP project which had focused mainly on small Arctic pond ecosystems on the Alaskan Arctic coastal plain. It was thought desirable to study larger, deeper lakes which contained fish to further generalizations developed during the IBP study. Initial research on Toolik Lake and the surrounding lakes and ponds focused on process studies such as annual primary productivity of the lake or the vertical migration patterns of the resident zooplankton. In 1983 the philosophy of the research changed with the funding of a more integrated programme. The fundamental question posed was whether Arctic lake and stream ecosystems are regulated from the bottom up by nutrient availability or from the top down by the density and activity of top predators. In 1987 the Toolik Lake area was designated an LTER (Long-Term Ecological Research) site, one of 18 such sites throughout the United States, Puerto Rico and the Antarctic. The research theme for the Arctic LTER also focuses on the regulation of Arctic ecosystems, whether regulation comes from the top down or bottom up. The Arctic LTER also incorporates a terrestrial component as well as a lake and stream component. 396 pp. Englisch.

The book includes 23 chapters which were originally written for the meeting by some of the world's foremost investigators. Chemists everywhere are carrying out exciting research that has important implications for the energy and fuels industries and for society in general. For the near future, coal resources will continue to be of great importance and science and technology of the highest order are needed to extend this fossil energy resource and to utilize it in an economical way that is also environmentally acceptable. These were the main purposes for the organization of this NATO ASI. The Institute constituted two working weeks on structure and reactivity of coal and so is the book. Through the presentation of many specific recent results on structure and characterization of coal and its products the potential of new instrumental techniques is presented in the first part of the book. Finally the reactivity of coals at different conditions both in laboratory and industry is discussed. We hope that the volume will be of great use to research workers from academic and industrial background. In addition it could serve as a textbook for a graduate course on coal science and technology.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 548 pp. Englisch.

The general aim of this meeting was to bring together mathemati cians and physicists who have worked in this growing field of contact between the two disciplines, namely this region where geometry and physics interact creatively in both directions. It 1S the strong belief of the organizers that these written con tributions will be a useful document for research people workin~ 1n geometry or physics. Three lectures were devoted to the deformation approach to quantum mechanics which involves a modification of both the associative and the Lie structure of the algebra of functions on classical phase space. A.Lichnerowicz shows how one can view classical and quantum statistical mechanics in terms of a deformation with a parameter inversely propor tional to temperature. S.Gutt reviews the physical background of star products and indicates their applications in Lie groups representa tion theory and in harmonic analysis. D.Arnal gives a rigorous theory Vll viii PREFACI of the star exponential in the case of the Heisenberg group and shows how this can be extended to arbitrary nilpotent groups.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 204 pp. Englisch.

The meeting brought together academic, governmental and industrial experts from eight countries to discuss the increasingly important sUbject of the relations between civil and defence technologies. It was primarily funded under the Advanced Research Workshops Programme of NATO's Scientific Affairs Division, and was the first science policy workshop funded by the Programme. Additional financial support came from the Leverhulme Trust. The choice of topic, of speakers and, finally, of papers to be published was entirely ours. The conclusions reached were our own and those of the partIcipants. They were not in any way guided by NATO; nor do they represent NATO policy. We speak for all the participants in offering our thanks to the NATO SCIentific Affairs Division, especially Secretary General Durand and Dr. Craig Sinclair, for rnei r- generosity and encouragement. WIthout them this book would not exist. We thank the Leverhulme Trust for enabling assistance to be provided to the Workshop Directors, in the form of lain Bate, who himself played a major part in the success of the meeting. The staff of Wiston House must also be thanked for prOViding an admirable environment for the meeting. For secretarial support prior to the meeting we thank Gill Miller and Lesley Price. Finally, we offer special thanks to Mrs. Yvonne Aspinall for converting all the papers, in whatever state they were presented, into camera-ready copy with such professionalism and gOOd humour. 320 pp. Englisch.
