Taschenbuch. Condizione: Neu. Neuware -Atoms in strong radiation fields are interesting objects for study, and the research field that concerns itself with this study is a comparatively young one. For a long period after the ~scovery of the photoelectric effect. it was not possible to generate electro magnetic fields that did more than perturb the atom only slightly, and (first-or~er) perturbation theory could perfectly explain what was going on at those low intensities. The development of the pulsed laser bas changed this state of affairs in a rather dramatic way, and fields can be applied that really have a large, or even dominant influence on atomic structure. In the latter case, w~ speak of super-intense fields. Since the interaction between atoms and electromagnetic waves is characterized by many parameters other than the light intensity, such as frequency, iQnization potential, orbit time, etc., it is actually quite difficult to define what is exactly meant by the term 'super-intense'. Obviously the term does not have an absolute meaning, and intensity should always be viewed in relation to other properties of the system. An atom in a radiation field can thus best be described in terms of various ratios of the quantities involved. The nature of the system sometimes drastically changes if the value of one of these parameters exceeds a certain critical value, and the new regime could be called super-intense with respect to that parameter.…

Taschenbuch. Condizione: Neu. Neuware -The present work is aimed at filling a hiatus in the literature dealing with the Young Hegelians and the early thought of Karl Marx. Despite the prevalent view in the past few decades that Bruno Bauer played an important part in the radical activity of Hegel's young disciples in the eighteen forties in Germany, no comprehensive work has so far been published on the relations between Bauer and Marx. In 1927 Ernst Bar nikol promised to write a monograph on the subject, but he never did. For the purpose of this study I perused material in numerous library collections and I would like to express my gratitude to the staff of the following institutions: Tel Aviv University Library, the Library and Archive of the International Institute of Social History in Am sterdam, the Heidelberg University Library, the Library of Gottingen University, the Tiibingen University Library, Frankfurt University Library, the State Library at Marburg, the Manuscript Department of the State Archives in Berlin.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 268 pp. Englisch.…

Taschenbuch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -The plastic forming of metals is a branch of technology, in which great progress has been achieved mainly by collecting practical data resulting from long-time experience. The contribution of theoretical analysis to this progress is not significant. The common argument was, that such an analysis is too difficult and often even impossible. However, the constantly increasing significance of coldwork processing in industrial practice and the progress in the automatic control of these processes, demanding a broad knowledge of the influence of various parameters, and also the need to improve the mechanical behaviour of coldworked elements have proved beyond doubt that better understanding of the theory of plastic forming processes is necessary. This general trend has become evident in several recent publications in recent years, even though these represent only the engineering, approximate approach to theoretical analysis. Recent significant progress in the mathematical theory of plasticity allows to build an analysis of plastic forming processes on a more sound basis. In particular there have been developed graphical methods by means of which slip-line and hodograph meshes are constructed for plane strain and axially symmetric problems. These graphical methods yield not only the required forces but also the. mode of plastic deformation, even for very complex problems. Numerical procedures also give good results if the digital computer technique is employed. 384 pp. Englisch.…

Taschenbuch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -Recent advances in the instrumentation used to observe star forming regions in both our own Milky Way and in external galaxies have transformed the subject from a phenomenological pursuit into an increasingly unified, physical science. High resolution centimetre, millimetre, infrared, and optical studies of local star forming clouds have allowed us to probe the physics of star formation down to spatial scales approaching those of the solar system. These developments make it possible to better constrain the basic physical processes underlying star formation itself. At the same time, these new instruments have placed extragalactic studies on a footing detailed enough to allow comparison with star forming regions within our own galaxy. This revolution means that we will soon be able to link the physics of local star forming regions to the global star forming properties of galaxies. The entire structure of this NATO Advanced Study Institute was designed to explore this new view of the subject. This Institute on 'Galactic and Extragalactic Star Formation' was held from June 21 -July 4, 1987 at the Conference Centre in the village of Whistler, British Columbia, Canada. The informal atmosphere of this lovely mountain resort stim ulated many valuable scientific exchanges. The Institute was funded by a major grant from NATO Scientific Affairs. Additional financial and I.I1oral assistance was provided by the Canadian Institute for Theoretical Astrophysics (CITA) and Mc Master University. 688 pp. Englisch.…

Taschenbuch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -Where do you begin to look for arecent, authoritative article on the diagnosis or management of a particular malignancy The few general onco logy textbooks are generally out of date. Single papers in specialized journals are informative but seldom comprehensive; these are more often preliminary reports on a very limited number of patients. Certain general journals fre quently publish good in-depth reviews of cancer topics, and published sym posium lectures are often the best overviews available. Unfortunately, these reviews and supplements appear sporadically, and the reader can never be sure when a topic of special interest will be covered. Cancer Treatment and Research is aseries of authoritative volumes which aim to meet this need. It is an attempt to establish a critical mass of oncology literature covering virtually all oncology topics, revised frequently to keep the coverage up to date, easily available on a single library shelf or by a single personal subscription. Wehave approached the problem in the following fashion. First, by divid ing the oncology literature into specific subdivisions such as lung cancer, genitourinary cancer, supportive care, etc. Second, by asking eminent autho rities in each of these areas to edit a volume on the specific topic on an annual or biannual basis. Each topic and tumor type is covered in a volume appearing frequently and predictably, discussing current diagnosis, staging, markers, all forms of treatment modalities, basic biology, and more. 328 pp. Englisch.…

The main intention of the conference was to allow each contributor to deliver a personal review of his own field, indicating recent develop ments and current practice. This volume, representing the proceedings of that meeting, is not intended as a comprehensive textbook of paedi atric endocrinology but rather as a series of personal narratives. I wish to express my thanks to the Chairmen, who so ably stimulated discussion, and to Miss Gillian Andrew, Conference Secretary of the Royal College of Physicians, and her colleagues, for providing invalu able help in the organization of the conference.

Taschenbuch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -This is a textbook devoted to mathematical programming algorithms and the mathematics needed to understand such algorithms. It was mainly written for economists, but the mathematics itself obviously has relevance for other disciplines. It is a textbook as well a~ in parts, a contribution to new knowledge. There is, accordingly, a broad ordering of climbing sophistication, the earlier chapters being purely for the student, the later chapters being more specialist and containing some element of novelty on certain points. The book is edited in five parts. Part I deals with elementary matrix operations, matrix inversion, determinants, etc. Part II is mainly devoted to linear programming. As far as students' readability is concerned, these two parts are elementary undergraduate material. However, I would claim, in particular with respect to linear programming, that I do things more efficiently than the standard textbook approach has it. This refers mainly to the search for a feasible solution i.e. Chapter 9, and to upper and lower limits, i.e. Chapter 10. I have also argued that the standard textbook treatment of degeneracy misses a relevant problem, namely that of accuracy. In short, I would invite anyone who has the task of writing or designing an LP-code, to first acquaint himself with my ideas. viii INTRODUCTION Parts III and IV are concerned with nonlinear programming. 804 pp. Englisch.…

Taschenbuch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -This volume contains the major portion of the material given at the NATO Advanced Study Institute, held at the University of Strathclyde, Glasgow, UK. , September 6th-18th, 1981. The original idea germin ated in a conversation between the organisers on a cold December night in 1978 in the depths of the Oxfordshire countryside. At that time we felt that the chemical physics of macromolecules in the solid state was running on two parallel tracks, namely structure and dynamics. The contact between the two appeared to be slight. We were also concerned that the degree of srecial knowledge now required for any one technique essentially prevented people from learning the important features of other investigation methods. Consequently, we have attempted to bring together leading authorities on both structural and dynamic properties of solid polymers in the hope that the combination of both types of discussion will be synergistic. The choice of main subjects is our own and we are aware that some areas have been omitted. HOvlever, to be comprehensive would have made an already large volume enormous. Y'Je therefore chose to concentrate on what were, in our opinion, the major areas. Nonetheless, it is apparent that much ori~inal material appears here, especially in those contri butions which are more theoretical in concent, the full experimental iMnlications of which have yet to be investigated. 492 pp. Englisch.…

Taschenbuch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -In the last few years a surprisingly large number of new experimental techniques have been devised to probe, often with great subtlety, into the electronic structures of inorganic substances. Thus in favourable cases one now has the opportunity of locating and assigning electronically excited states over a 1 vast energy range stretching from tens of cm- above the ground 1 6 state up to some 10 cm- The techniques are extremely dis parate in background, involving (among others) linearly and circularly polarised electromagnetic radiation, electron kinetic energy analysis and neutron scattering. Furthermore, practition ers of many of the techniques may not be aware of how the information which they are obtaining overlaps and complements that obtained by other techniques. The time therefore seemed ripe to bring together a group of experts to survey, for an audience of inorganic chemists, the basic theories and experim ental procedures relevant to the different techniques, and the relations between them. In pursuing this aim we were fortunate in having the very generous financial backing of N. A. T. O. , through their Advanced Study Institutes programme, and the present volume records the substance of lectures given at the Institute which took place at the Inorganic Chemistry Laboratory and St. John's College, Oxford, from 8-18 September 1974. 552 pp. Englisch.…

Taschenbuch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -In recent years methods have been developed to study cardiac function, myocardial blood flow and myocardial metabolism with radionuclides. These developments have been facilitated through the introduction of new radiopharmaceuticals, the design of special gamma cameras and dedicated computer systems. However, part of the information provided by nuclear cardiology can also be obtained through other investigations such as echocardiography, exercise electrocardiography and cardiac catheterisation with ventriculography and coronary arteriography. Thus the practising physician must select the most appropriate methodes) of investigation for each patient. Such choices should be based on proper understanding of both the value and the restrictions of each method. In this book the state-of-the-art in nuclear cardiology is reviewed, including radionuclide angiography for analysis of left and right ventricu lar function and for measurement of shunts and regurgitation volumes, perfusion scintigraphy and other methods for measurement of myocardial bloodflow and metabolism and computer processing of radio nuclide Images. Each chapter has been written by an expert from either Europe or the USA, who has contributed to the developments in his particular field. The principles of each method of investigation are described, as well as the precautions that should be taken in order to obtain high quality data. Guidelines are provided for the interpretation ofthe data based on studies in various centers where the methods were developed and tested. 268 pp. Englisch.…

Taschenbuch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -Spectral line formation theory is at the heart of astrophysical diagnostic. Our knowledge of abundances, in both stellar and interstellar contexts, comes almost enti rely from line analysis, as does a major fraction of our ability to model stellar atmospheres. As new facets of the universe become observable so the techniques of high reso lution spectroscopy are brought to bear, with great reward. Improved instruments, such as echelle spectrographs, employ ing detectors of high quantum efficiency, have revolutioned our ability to observe high quality line profiles, although until now this ability has been confined to the brightest stars. Fabry-Perot interferometers and their modern deriva tives are bringing new ranges of resolving power to studies of atomic and ionic interstellar lines, and of course radio techniques imply exceedingly high resolution for the cool interstellar medium of molecules and radicals. Telescopes in space are extending the spectral range of these types of observations. Already the Copernicus and IUE high resolution spectrographs have given us a tantalizing glimmer of what it will be like to obtain ultraviolet spectra with resolution and signal to noise ratio approaching those obtainable on the ground. Fairly soon Space Telescope will be producing high resolution spectroscopic data of unparal leled quali ty and distance range. As often happens in astro physics the challenge is now coming from the observers to the theorists to provide interpretational tools which are adequate to the state of the data. 468 pp. Englisch.…

Taschenbuch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -This volume contains the lectures presented at an Advanced Study Institute on 'Magnetic Resonance Techniques in Fossil Energy Problems,' which was held at the village of Maleme, Crete, in July of 1983. As of this writing, a different popular attitude prevails from that when the ASI was proposed as far as how critical the world energy picture is. In the popular press, a panglossian attitude (the 'petroleum glut' of the 80's) has replaced the jeremiads of the 70's ( a catastrophic 'energy crisis'). Yet, there are certain important constants: (a) for the foreseeable future, fossil energy sources (petroleum, coal, oil shale, etc. ) will continue to be of paramount importance; and (b) science and technology of the highest order are needed to extend the fossil ener~y resource base and to utilize it in a cost-effective manner that is also environmentally acceptable. It is precisely this second item that this volume addresses. The volume introduces the phenomenology of magnetic resonance ~n a unified and detailed manner, starting from the behavior of spins in a magnetic field and proceeding to a density matrix consideration of the phenomena involved. The various important parameters of NMR and EPR are discussed in detail, as well as their significance and the information that may be obtained from their proper consideration. Advanced topics are then considered, including line-broadening interactions, coherent averaging and multiple quantum methods in NMR, ENDOR, electron spin echoes, dynamic nuclear polarization. problems of quantifi cation, 2-Dimensional N}1R, Mossbauer, and instrumentation. 824 pp. Englisch. …

Taschenbuch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -The progress that has been made recently and the consequent increased interest in Low-Dimensional Solids has been impressive. This volume contains the latest advances concerning the chemistry and physics of, particularly, one dimensional solids, which were treated at the 1979 Advanced Study Institute, held in Tomar, Por tugal. The subject is treated starting from basic concepts on the physics of one dimension up to the design of new materials and includes technological and scientific applications. The book therefore should be of interest to solid state physicists, syn thetic chemists and scientists concerned with materials science and technology. Contrary to some pessimistic views, the subject continues to be of interest and very much alive indeed, and new perspecti ves are open particularly in the domain of new materials and conducting polymers and their technological interest.

Taschenbuch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -R.E. Newell President, International Commission on Climate International Association of Meteorology and Atmospheric Physics Water is the active ingredient in the global climatic system, its physical properties ensuring that it plays a major role. Its high thermal capacity provides a mechanism for moderating mid latitude winter temperatures; solar energy is absorbed by the surface layers of the middle latitude oceans in summer and is released to the atmosphere in winter as the ocean cools. The variation of saturation vapour pressure with temperature is the factor which causes oceanic surface temperatures at low latitudes to be limited by evaporation to values near 29°C, thereby limiting tropical marine air temperatures to about the same value. The substantial amount of energy involved in phase changes - the latent heat - governs the passage of solar energy to the atmo sphere; visible solar radiation is absorbed at the Earth's surface, energy is supplied to evaporate water and the latent heat is released to the atmosphere when and where condensation occurs, which is often a considerable distance from the source of the moisture. The infrared radiative characteristics of water vapour, namely the broad vibration-rotation bands typical of a triatomic molecule, permit it to act as the principal agent of energy loss from the atmosphere, throu ,h infrared radiation to space. 536 pp. Englisch.…

It was organized by the Working Group for Succession research on permanent plots, and the Working Group for Data-processing in phytosociology, both of the International Society for Vegetation Science. The editors of this volume represent both working groups and the organizing institute. They acknowledge the considerable material assistance provided by the Centre National de la Recherche Scientifique, Direction des relations exterieures de l'information, and Programme lnterdisciplinaire de Recherche sur I'Environnement (PIREN); the Conseil general de I'Herault; and the Ministere de I'Environnement et du Cadre de Vie. The Symposium was opened by Prof. M. Godron. The many lectures and poster contributions were organized around five themes. A complete list is added to this volume (Appendix). Abstracts of these contributions were sent in prior to the Symposium and collected by the CEPE in a volume 'Actes du Symposium sur Dynamique de la Vegetation dans les formations herbacees, les landes et les formations mediterraneennes ligneuses'. The 27 ela borated papers accepted for this volume are presented in roughly the same sequence. 300 pp. Englisch.…

Taschenbuch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -Since 1952, postgraduate courses for practising physicians and speci alists have been given by the Medical Faculty of the University of Leiden in the Boerhaave Quarter, in which most of its clinics and laboratories are located. During these years, recent advances in a wide variety of m~dical fields and subjects have been discussed by distin guished speakers from many countries. The steadily increasing atten dance has shown that, as could be expected from the rapid progress of modern medicine, there is a widely felt need for this form of postgra duate study. In 1957, therefore, the Leiden Medical Faculty appointed a permanent committee for the organization of postgraduate medical education. Of the courses given since then, certain material proved to have sufficient immediate scientific value to justify publication, and it now gives the Committee great pleasure to announce that in collaboration with the Leiden University Press it will publish the Boerhaave Series for Postgraduate Medical Education. The first volume of this new series is the product of the course on Human Blood Coagulation given in Novem ber 1968. It is our hope that this book will prove valuable not only to those who participated in the course but also to many others working in this and associated fields. 428 pp. Englisch.…

The Scandal of Father 'The Hennit 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. 208 pp. Englisch.…

This item is printed on demand - it takes 3-4 days longer - Neuware -Two years ago, just before the Prague meeting of the International Astronomical Union, Armin Deutsch made the bold suggestion that the space spectroscopists hold a joint symposium with the ground-based observers. At that time the rocket observa tions of stellar spectra seemed too meagre to make such a meeting worthwhile, but we proceeded in the hope that there would be significant new results available by 1969. IAU Commissions 29 and 44, on Stellar Spectra and Observations from Outside the Terrestrial Atmosphere respectively, agreed to sponsor the symposium so that the organization was given to the Joint Working Group of these commissions. Conse quently, the Organizing Committee, which met first in Prague, consisted of A. Deutsch, M. W. Feast, L. Houziaux, V. G. Kurt, N. G. Roman, J. Sahade, A. B. Underhill, and R. Wilson, with myself as Chairman. Later COSP AR was invited to join in spon soring the symposium and T. Chubb was added as their representative. We were specially pleased when C. de Jager invited us to the Netherlands and offered the services of the Utrecht Observatory for the local organization. He suggested we hold the meeting at the new Lunteren Conference Centre located in a wooded area some 35 km east of Utrecht. The modern facilities of the Centre and the hospi tality of its staff contributed much to the enjoyment of our four days there. 380 pp. Englisch.…

This item is printed on demand - it takes 3-4 days longer - Neuware -The idea for this volume came during the dryland sessions of the Association of American Geographers meeting in San Diego in April, 1992. The large number of papers devoted to aeolian processes and landforms indicated to me that aeolian geomorphology had come of age and the last 15 years or so had produced a plethora of papers, books, and edited volumes on all aspects of aeolian geomorphology. Chapter one is my tentative attempt to place develop ments in aeolian geomorphology in a historical perspective and to contemplate some thoughts about the future. The fourteen papers selected address a wide range of issues ranging from micro-scale studies devoted to aeolian dust, sediment transport, and rock varnish in ventifacts to medium-scale studies of dunes and dune forms, reverse desertification, and macro-scale studies of ergs and sand transport pathways. The American Southwest, particularly the spectacular and unique Mojave Desert of California, is featured prominently in seven chapters. I hope this volume provides students and colleagues some new perspectives in aeolian geomorphology as well as pathways for future work. 348 pp. Englisch.…

Taschenbuch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -Population genetics is the mathematical investigation of the changes in the genetic structure of populations brought about by selection, mutation, inbreeding, migration, and other phenomena, together with those random changes deriving from chance events. These changes are the basic components of evolutionary progress, and an understanding of their effect is therefore necessary for an informed discussion of the reasons for and nature of evolution. It would, however, be wrong to pretend that a mathematical theory, depending as it must on a large number of simplifying assump tions, should be accepted unreservedly and that its conclusions should be accepted uncritically. No-one would pretend that in the event of disagreement between observation and mathematical prediction, the discrepancy is due to anything other than the inadequacy of the mathematical treatment. The biological world is, of course, far too complex for the study of population genetics to be simply a branch of applied mathematics, so that while we are concerned here with the mathematical theory, I have tried to indicate which of our results should continue to apply in a context wider than that in which they are formally derived. The difficulties involved in the joint discussions of mathematical and genetical problems are obvious enough. I have tried to aim this book rather more at the mathematician than at the geneticist, and for this reason a brief glossary of common genetical terms is included. 160 pp. Englisch.…

This item is printed on demand - it takes 3-4 days longer - Neuware -The invention of the Laser, 25 years ago, has become an innovation with established industrial technology extended through diverse areas of economic viability (a 25% sales annual growth), and promising market perspectives. In organizing an European Intensive Course on Applied Laser Tooling, it seemed opportune to bring together an international group of scientists to provide an appraisal of industrial Lasers, system integration, and sensitive areas of Laser beam material interaction, while emphasizing those areas which promise to have major impact both in science and technology. Tutorial papers and reports on latest developments both in research and industrial manufacturing were complemented by video and film projections to show the wide variety of applications in industry, stressing the combination of Lasers with other technologies, mainly CNC and Robots. The large participation by the industry fulfilled the intended interaction and cross-fertilization between the scientific, technological and industrial community, reinforcing the innovative capacity readily demonstrated at panel discussions. It was neither possible nor planned to cover all the aspects in full depth. Efforts were addressed to selected areas where discussion of advanced knowled~e and technology topics would stimulate further progress of Laser tooling (in main directions: software, hardware and peopleware). Laser tooling was then discussed in light of its major applications covering Laser beam robotic manipulation towards flexible manufacturing systems. The following articles give a fair account of the course programme. 296 pp. Englisch.…

As one will know, the Edinburgh Faculty of Medi cine was founded in 1726 on the principles guiding the Leiden Faculty of Medicine at that time, on the instigation of John Monro I, who had studied medicine in Leiden under the famous Boerhaave. These old ties were revived some 8 years ago, first by students, later by the Faculties themselves, with the special purpose to facilitate and en large the exchange of medical knowledge between two medical centres. One of the results of this was that it was considered whether physicians from both countries could not profit from the knowledge gained specific ally in both these faculties by letting the investigators from both faculties tell about their work within the framework of courses for post-academic medical training, in Leiden called the 'Boerhaave Courses'. 160 pp. Englisch.…

This item is printed on demand - it takes 3-4 days longer - Neuware -This publication reports the proceedings of a one-day seminar on The Application and Numerical Solution of Integral Equations held at the Australian National University on Wednesday, November 29, 1978. It was organized by the Computing Research Group, Australian National University and the Division of Mathematics and Statistics, CSIRO. Due to unforeseen circumstances, Dr M.L. Dow was unable to participate. At short notice, Professor D. Elliott reviewed Cauchy singular integral equations, but a paper on same is not included in these proceedings. The interested reader is referred to the recent translation of V.V. Ivanov, The Theory of Approximate Methods and their Application to the Numerical Solution of Singular Integral Equations, Noordhoff International Publishers, Leyden, 1976. An attempt was made to structure the program to the extent that the emphasis was on the numerical solution of integral equations for which known applications exist along with explanations of how and why integral equation formalisms arise. In addition, the programme reflected the broad classification of most integral equations as either singular or non singular, as either Fredholm or Volterra and as either first or second kind. 272 pp. Englisch. …

Taschenbuch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -The broad range of interdisciplinary concerns which are encompassed by the philosophy of science have this much in common: (I) they arise from reflection upon the fundamental concepts, the formal structures, and the methodology of the sciences; (2) they touch upon the characteristically philosophical questions of ontology and epistemology in a unique way, bringing to traditional conceptions the analytic apparatus of modern logic, and the new content and conceptual models of active scientific investigations. These sources are reflected in the present volume, which consists of the major portion of the papers presented to the Boston Colloquium for the Philosophy of Science in the academic year 1961-1962. There is no central theme nor any dominant approach in this colloquium. Initiated in 1960 as an inter-university interdisciplinary faculty group, the Colloqnium is intended to foster creative and regular exchange of research and opinion, to provide a forum for professional discussion in the philosophy of science, and to stimulate the development of academic programs in philosophy of science in the colleges and universities of metropolitan Boston. The base of the Colloquium is our philosophic and scientific community, as broad and heterodox as the academic, cultural and techno logical complex in and about this city. The Colloquium has been supported in its first full year, as an inter-institutional cooperative association, by a generous grant to Boston University from the U. S. National Science Foundation. We are most grateful for this help. 224 pp. Englisch.…

Taschenbuch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -The field of modern logic is too extensive to be worked through by open cast mining. To open it up, we need to sink shafts and construct adits. This is the method of most text books: a systematic exposition of a number of main topics, supplemented by exercises to teach skill in the appurtenant techniques, lays a secure foundation for subsequent dis cussion of selected questions. Compared with this, the present treatment is more like a network of exploratory drillings to show that it would be worthwhile to start mining operations, or to work the existing shafts and adits, as the case may be. Within this metaphor we may also describe the inherent weakness of this conception: once a cavity is pierced, the duct's capacity will in general not be sufficient to carry away the discovered riches. But whether we are concerned with a new or an already worked mine - at any rate, the experience should stimulate us into either reviving an existing system of shafts or even, in particularly fortunate cases, designing a new ap proach. 184 pp. Englisch.…

This item is printed on demand - it takes 3-4 days longer - Neuware -This book was written in 1968, and defended as a doctoral dissertation before the Philosophical Faculty at the University of Fribourg (Switzerland) in 1969. It treats of the systematic views of Hegel which led him to give to the princi ple of non-contradiction, the principle of double negation, and the principle of excluded middle, meanings which are difficult to understand. The reader will look in vain for the philosophical position of the author. A few words about the intentions which motivated the author to study and clarify Hegel's thought are therefore not out of place. In the early sixties, when occupying myself with the history of Marxist philosophy, I discovered that the representatives of the logical-positivist tra dition were not alone in employing a principle of demarcation; that those of the dialectical Marxist tradition were also using such a principle ('self-move ment') as a foundation of a scientific philosophy and as a means to delimit unscientific ideas. I aimed at a clear conception of this principle in order to be able to judge whether, and to what extent, it accords with the foundations of the analytical method. In this endeavor I encountered two problems: (1) What is to be understood by 'analytical method' cannot be ascertained un equivocally. 212 pp. Englisch.…
