This selection of papers that were presented (or nearly so!) to the Boston Colloquium for the Philosophy of Science during the seventies fairly re­ presents some of the most disturbing issues of scientific knowledge in these years. To the distant observer, it may seem that the defense of rational standards, objective reference, methodical self-correction, even the distin­ guishing of the foolish from the sensible and the truth-seeking from the...

This treatise is devoted to an analysis of the present state of the quantum theory of chemical reactions. It will be divided into three volumes and will contain the contributions to an international seminar organized by the editors. The first one, is concerned with the fundamental problems which occur when studying a gas phase reaction or a reaction for which the solvent effect is not taken into account. The two first papers show how the colli...

The purpose of this particular NATO Advanced Study Institute is to contribute to the dissemination of advanced knowledge and the formation of contacts between scientists from different countries. The Institute is meant to have a substantial teaching component while also providing a forum for discussion at the highest level. The NATO Advanced Study Institute on Progress in Biomechanics was held July 10-21, 1978 in Ankara, Turkey and the Proceed...

The International Astronomical Union has encouraged the study of our galaxy through a series of symposia. This volume contains the proceedings of IAU Symposium No. 84 on the Large-Scale Characteristics of the Galaxy, held in College Park, Maryland, from June 12 to 17, 1978. Symposium No. 84 was jointly sponsored by IAU 2ommission 33, Structure and Dynamics of the Galactic System, and by Commission 34, Interstellar Matter and Planetary Nebulae....

For some years I have felt there was a need for a single, comprehen­ sive, reference book on exploration geology. Numerous textbooks are available on subjects such as geophysical prospecting, exploration geochemistry, mining geology, photogeology and general economic geology, but, for the geologist working in mineral exploration, who does not require a specialist's knowledge, a general book on explora­ tion techniques is needed. Many undergrad...

The central role of the ribonucleic acids (RNA) in mediating the expression of information encoded in DNA in living cells is now well established. Research in this area of biology continues at a remarkable rate, and new and significant information appears almost daily in a wide range of journals, published symposia and specialist reviews. The diverse nature of this information makes it difficult for the newcomer to the field of RNA biochemistr...

The Photoelectric Spectrometry Group was formed in July 1948 in Cambridge. The Group was born out of a need for a forum of users to discuss problems and methodology associated with the new era of photoelectric spectrometers. Over the years the aims and objectives of the Group have been broadened to include many aspects of ultraviolet and visible spectrometry. In 1973, the Group renamed itself the UV Spectrometry Group (UVSG). The techniques of...

Our objectives may be briefly stated. They are two. First, we have sought to provide a compact and digestible exposition of some sub-branches of mathematics which are of interest to economists but which are underplayed in mathematical texts and dispersed in the journal literature. Second, we have sought to demonstrate the usefulness of the mathematics by providing a systematic account of modern neoclassical economics, that is, of those parts o...

Bacteria adhere to and colonize almost any surface. Within minutes after sub­ merging a solid object in seawater or freshwater, the surface becomes colonized by adherent micro-organisms, and the earliest organisms to adhere are bacteria. Adherent colonies of bacteria have also been observed on particles of sand, soil, other bacteria, plant tissues, and a variety of animal tissues. Shortly after birth, the skin and the mucosal surfaces of the u...

Although the most sophisticated fault diagnosis and condition monitoring systems have their origin in the aerospace and nuclear energy industries, their use is by no means restricted to such areas of 'high technology'. Modern machinery in most industrial plants is now so complex and expensive that mechanics find it increas­ ingly difficult to detect failure by, for instance, recognising changes in sound 'signatures', and few plants can afford ...

Since the first statement of the aims and methods of the Cambridge Growth Project, which appeared in 1962 as the first number of our former series A Programme for Growth, we have produced a volume on the state ofthe model and on projections derived from it at roughly five year intervals: Exploring 1970 (1965), Exploring 1972 (1970) and now the present book. A comparison of these publications shows the directions in which we have developed our ...

Mathematics for infinite dimensional objects is becoming more and more important today both in theory and application. Rings of operators, renamed von Neumann algebras by J. Dixmier, were first introduced by J. von Neumann fifty years ago, 1929, in [254] with his grand aim of giving a sound founda­ tion to mathematical sciences of infinite nature. J. von Neumann and his collaborator F. J. Murray laid down the foundation for this new field of m...

This book was written as a text, although many may consider it a mono­ graph. As a text it has been used several times in both the one-year graduate quantum-mechanics course and (in its shortened version) in a senior quantum mechanics course that I taught at the University of Texas at Austin. It is self-contained and does not require any prior knowledge of quantum mechanics. It also introduces the mathematical language of quantum mechanics, st...

Insects as a group occupy a middle ground in the biosphere between bac­ teria and viruses at one extreme, amphibians and mammals at the other. The size and general nature of insects present special problems to the student of entomology. For example, many commercially available in­ struments are geared to measure in grams, while the forces commonly en­ countered in studying insects are in the milligram range. Therefore, tech­ the study of insec...

Project Set Strategies focuses on an issue of vital concern to corporate managers: the development and implementation of strategy. Regretfully, this topic has received too little attention in the literature of finance and has been treated in­ completely in the management journals. In fact, not everyone recognizes that it falls within the sphere of finance. However, since the important issues discussed in this book strategically shape the desti...

This volume contains a series of lectures presented at the 5th Course of the International School of Astrophysics held in Erice (Sicily) from July 1st to July 14, 1979 at the "E. Majorana" Centre for Scientific Culture. The course was fully supported by a grant from the NATO Advanced Institute Programme. It was attended by about one hundred participants from ten countries. Since the discovery of the first extra-solar X-ray source in the early ...

HOW TO READ THE BOOK: SOME COMMENTS This book is the lasting result of the first NATO Advanced Study Institute on Speech, held at the Centre Culturel du Chateau de Bonas, from June 26 to July 7, 1979. The intent of a NATO ASI is primarily to provide high level tutorial coverage of a field in WhlCh research is active, undoubtedly speech generation and understanding is one at the present time. Thus 12 surveys are offered by some of the best spec...

This volume is the fourth in the series of the Proceedings of the College Park Colloquia on Chemical Evolution. These Colloquia, and the resulting Proceedings, are presented in the interest of fostering the impact of the interdisciplinary nature of chemical evolu­ tion on contemporary scientific thought. vii EDITORS'INTRODUCTION The Fourth College Park Colloquium on Chemical Evolution was held on October 18 - 20, 1978 at the University of Mary...

Most complex biological systems, such as enzyme pathways, are effec­ tively controlled near the beginning of the process. There is increasing evidence that the same is true for the immune system, with the initial interactions between antigen, antigen-presenting cells, and T cells hav­ ing a paramount influence on the ensuing events. Thus, analysis of the early stages of the immune responses has been a preoccupation of many immunologists. This ...

The authors of a recent textbook on the Economics of Development (P. A. Yotopoulos and J . B. Nugent, 1976) chose as the title of their first chapter 'The Record of Economic Development and Disillusionment with Development Economics'. It is striking that dissatisfaction with this young branch of the tree of economics has become so strong that a textbook treatment of the subject matter takes Disillusionment as its point of departure. True, the ...
