Buch. Condizione: Neu. Neuware - The last decades have seen major reformations in the philosophy and history of science. What has been called 'post-positivist' philosophy of science has introduced radically new concerns with historical, social, and valuative components of scientific thought in the natural sciences, and has raised up the demons of relativism, subjectivism and sociologism to haunt the once calm precincts of objectivity and realism. Though these disturbances intruded upon what had seemed to be the logically well-ordered domain of the philoso phy of the natural sciences, they were no news to the social sciences. There, the messy business of human action, volition, decision, the considerations of practical purposes and social values, the role of ideology and the problem of rationality, had long conspired to defeat logical-reconstructionist programs. The attempt to tarne the social sciences to the harness of a strict hypothetico deductive model of explanation failed. Within the social sciences, phenome nological, Marxist, hermeneuticist, action-theoretical approaches vied in attempting to capture the distinctiveness of human phenomena. In fact, the philosophy of the natural sciences, even in its 'hard' forms, has itself become infected with the increasing reflection upon the role of such social-scientific categories, in the attempt to understand the nature of the scientific enterprise.

Beth (Ed.): Cryptography - EUROCRYPT '82, LNCS 149, pp. 1-28, 1983. 0 Springer-Verlag Berlin Heidelberg 1983 3 Having all of a sudden left the shady corner of semi-military art, modern cryptography has become a central topic of research in all areas of communication science. Definitions (cf. Bauer pp. 31 - 48) Cryptographic measures are applied to p- tect valuable data during transmission against unwanted interception INTERCEPTOR Fig. A: passive violation and (possibly undectable) forgery . Fig. 2: acti-se violation In accordance with the subsequent paper of Bauer (pp. 31 - 481, the technique applied to meet these requirements is called en- tion. In this process the transmitter enciphers (or encrypts) a plaintext message into a ciphertext. 4 ciphertexc ciphering Fig. 3: The Wire-tap-channel This transformation is called a cipher(function) which the au- rized receiver deciphers (decrypts). An enemy is a person or institution who wants illegal access to the messages. Assuming that the enemy can only get hold of the ciph- texts, he has to perform a cryptanalysis in order to reconstitute the plaintexts. To add to the difficulties for a cryptanalyst, the cipher functions are chosen to a varying parameter, called the key. A generator cryptosystem consists of a class of injective cipher functions ES:M-C , mapping plaintext messages(EM) into ciphertexts(EC) . The parameter s runs through the set K of keys. These formulations are best demonstrated by the basic, classical examples. 416 pp. Englisch.

Taschenbuch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -In this small book I have tried to confine myself to the absolute necessities in a field which requires a knowledge of both biology and physics. It is meant as a primer for biological undergraduates. I hope it will lead some of them to further, more advanced, study. It has not been easy to present the subject in so few pages, and I am aware of many omissions. I hope readers will agree that it is best to concentrate on a small number of topics, which together constitute an essay on plant-atmosphere relationships. Advanced students will be able to take the subject further if they look up some of the references. Text books that I particularly recommend are those by Monteith [38] and Campbell [lOO]. If the reader intends to carry out research investigations he should also consult Fritschen and Lloyd [105] for an introduction to instrumentation in environmental biophysics. 96 pp. Englisch.

Taschenbuch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -With consumer goods, as weil as consumer durables, the market is obscured because of product differentiation, in for example, the use, of trade marks, and the advertising and get-up of products, and this presents arealproblern in the protection of consumers. After a general demarcation of the forms, techniques and functions of product differentiation, an investigation is made into the correlation between the law and product differentiation; first, regarding pharmaceutical products and, then, though only by way of reconnaissance, for foodstuffs and cosmetics. Both in the general descriptive part and in the parts dealing with various sectors, attention is also paid to product differentiation as a source of the geographical division of markets. In a later chapter, certain general Observations on the law and socially undesirable product differentiation are developed. Here special attention is paid to trade mark law and regulations relating to misleading and dishonest advertising. The survey shows that, in the light of the existing economic model, improved consumer protection against the representation of product differ ences which hardly exist, can best be effected by means of regulations and other initiatives concerned with the supply of information, such as labelling requirements.

Taschenbuch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -Most of the properties of a metal-electrolyte interface, even the spe cific nature of an electrode reaction, proneness of a metal to cor rosion, etc., are primarily determined by the electrical double layer (EDL) at this boundary. It is therefore no surprise that for the last, at least, one hundred years intent attention should have been centered on EDL. So much of material has been gathered to date that we are easi ly lost in this maze of information. A substantial part of the attempts to systematize these facts is made at present within the framework of thermodynamics. Such a confined approach is undoubtedly inadequate. The Gouy-Chapman theory and the Stern-Grahame model of the dense part of EDL developed 40-70 years ago, tailored appropriately to suit the occasion, inevitably underlie any description of EDL. This route is rather too narrow to explain all the facts at our disposal. A dire necessity has thus arisen for widening the principles of the micros copic theory. This is precisely the objective of our monograph. Fur thermore, we shall dwell at length on the comparison of the theory with experiment: without such a comparative analysis, any theory, however elegant it may be, is just an empty drum. 188 pp. Englisch.

This item is printed on demand - it takes 3-4 days longer - Neuware -It was particulary appropriate that the IAU Symposium N° 100 be held in Besan~on in 1982 (August 9-13), since this coincided with the 100th anniversary of the Observatoire de Besan~on. The meeting was held on the campus of the Universite de Franche-Comte and was sponsored by IAU commission 28 and co-sponsored by commissions 33 and 40. It was organized under the auspices of the Ministere de l'Education Nationale, the Centre National de la Recherche Scientifique and the Institut National d'Astronomie et de Geophysique. It was attended by 166 scien tists from 22 countries. The subject of the symposium was internal kinematics and dynamics of galaxies and it was aimed to confront recent theoretical developments in this field with the wealth of new observational mate rial obtained during the last few years. Barred galaxies and spiral structure were two major topics, though unfortunately at the last minute the main proponent of one of the spiral formation theories was unable to attend. The program included 23 reviews, 53 contributions and 39 poster papers, and there was ample time for discussion. 452 pp. Englisch.

Taschenbuch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -Are Western epistemology, metaphysics, methodology and the philosophy of science grounded only in men's distinctive understandings of themselves, others, and nature Does this less than human understanding distort our models of reason and of scientific inquiry In different ways, the papers in this collection explore the evidence for these increasingly reasonable and intriguing questions. They identify how it is distinctively masculine perspectives on masculine experience which have shaped the most fundamental and formal aspects of systematic thought in philosophy and the natural and social sciences - precisely the aspects of thought believed most gender-neutral. They show how these understandings ground Aristotle's biology and metaphysics; the very definition of the problems of philosophy in Plato, Descartes, Hobbes and Rousseau; the `adversary method' which is the paradigm of philosophic and scientific reasoning; principles of individuation in philosophical ontology and the philosophy of language; individualistic assumptions in psychology; functionalism in sociological and biological theory; evolutionary theory; the methodology of political science; Marxist political economy; and conceptions of `objective inquiry' in the social and natural sciences. These essays also begin to identify for us the distictive aspects of women's experience which can provide the resources needed for the creation of a truly human understanding. Audience: The book will be of interest to those involved in epistemology, and philosophy of the natural and social sciences, as well as feminist scholars in philosophy. The work will also be of value for theorists, methodologists, and feminist scholars in the natural and social sciences. 356 pp. Englisch.

Neuware -If Charles Babbage is to be regarded as the father of modern day computer technology, then surely the Countess Augusta Ada Lovelace, after whom this new language is named, must be remembered as its midwife. It was she, the daughter of England's poet Lord Byron, who translated the work of the Italian mathematician L.F. Menabrea, attaching her own scientific commentaries on the dissimilarities between the difference engine and the analytical engine. It was Lady Lovelace, the great lady of computers, who delivered the notes and loosely organized writings of Babbage, with her own invaluable amendments, to a world not quite ready to receive them. The Ada language effort has employed hundreds, if not thousands, of minds and a healthy sum of money since its conception. Ada was fostered by the High Order Language Working Group (HOLWG), chartered by the U.S. Department of Defense in January of 1975 with the overall objective of developing a systematic approach to improved use of software by the military. One would think the Pentagon an unlikely foster parent for a new computer language. Regardless of its lineage, the question that begs asking is, of course - Why The answer is by no means a simple one, but some brief background may help to clarify the matter. At present, the Department of Defense is the largest software consumer on earth, employing roughly 400 different computer languages and dialects. The situation, some have commented, is at best untidy.Springer-Verlag KG, Sachsenplatz 4-6, 1201 Wien 144 pp. Englisch.
