Neuware - When Critical Issues in Psychiatry was conceived, there were several sub jects I considered to be of crucial importance in a series devoted to residents and clinicians in psychiatry, as well as to other mental health professionals. Of prominence was the pressing need for an in-depth and scholarly exam ination of the interface between medicine and psychiatry. I had been amazed to find that not a single book, to my mind, adequately addressed the psy chological symptoms and manifestations of both common and rare medical illness. It seemed to me that there was a need for a work which would achieve the following goals: First, it would assist in the differential diagnosis of functional psychiatric symptoms versus symptoms secondary to recog nized or unrecognized medical illness; second, it would elucidate the psy chological symptoms resulting from pharmacologic and other therapeutic interventions in medical illness; and third, it would examine the use of psychopharmacological agents in the presence of medical illness and the drugs used to treat that illness. Dr. Jefferson is Board Certified in both internal medicine and psychiatry, and both Drs. Jefferson and Marshall have extensive clinical experience from their many years of consultation/liaison work in psychiatry. Their experience and expertise have resulted in what I believe to be a monumental contri bution to the literature.

It is now possible to produce at the laboratory scale, ultra-short 13 pulses with a duration of 100 femtoseconds (10- second) and a power of the order 12 of 1 terawatt (10 Watt). Under these conditions, very high peak intensities may be obtained and electric fields exceeding typical electron binding fields in atoms are generated. The interaction of an atom or a molecule with such electromagnetic fields has a highly non-linear character which leads to unexpected phenomena. Amongst them, - above-threshold ionization (ATI) i.e. the absorption of additional photons in excess of the minimal number necessary to overcome the ionization potential and its molecular counterpart, above-threshold dissociation (ATD); - generation of very high harmonics of the driving field; - stabilization of one-electron systems in strong fields. These processes were the main topics of two international meetings which were held in 1989 and 1991 in the United States under the common name SILAP (Super-Intense Laser-Atom Physics).

Fogarty International Center for Advanced Study in the Health Sciences, National Institutes of Health, October 30 to November 1, 1972. As part of its advanced study program, the Center conducts workshops, seminars, and conferences on topics related to the biomedical interests of the Scholars-in Residence. Professor Torsten Teorell came to the Center in 1970 as one of the first Scholars. In 1971 and 1972, he spent several months at the Center devoting his attention to contemporary problems in the application of pharmacoki netics to experimental and clinical pharmacology. As one of the founders of pharmacokinetics, Professor Teorell has made many contributions to the field since he first presented a formal multicompartment model for the analysis of drug action and drug metabolism in 1937 (Teorell, 1937). Since the appearance of his original paper, pharmacodynamics, or pharmacoki netics, has become increasingly important as a tool for the study of drug action in patients. The translation of experimental pharmacological findings into therapeutic regimens is today increasingly dependent on ade qua te models of drug action. The purpose of the conference, of which this book is the proceedings, was to discuss contemporary findings in this important biomedical research field. The conference program was designed by Professor Teorell with the help of a small committee which included Drs. Edward R.

Though cancer remains a leading cause of death for children and young adults, more victims of child hood cancer today will survive than will die. The therapeutic advances and the optimism they instill have prompted researchers and clinicians to analyze the impact of cancer upon young patients and their famil,ies and to devise more effective intervention strategies. Hope and survival, juxtaposed with the continuing high mortality associated with certain forms of the illness, add new challenges to management of the psychosocial aspects of cancer. To respond to these challenges we need research as rigorous as that which continues to make inroads in treating the physical illness. This specific concern for the needs of children suffering from cancer and their families has paralleled an increasing sensitivity on the part of the medical community and the public at large to the limitations of specialized, high technology health care practices.

Neuware - For the last eighteen years we have been deeply involved in a cooperative effort with our Latin American colleagues in genetics, biochemistry, physiology, and molecular biology. We have been in close contact with scientists in a number of centers and have helped to organize symposia, workshops, and so forth, in an effort to accelerate their development and make their substantial work known. These symposia in Latin America have been quite successful. The fifteenth will take place in Brasilia in 1977. At the request of colleagues, we are in the process of developing a similar series in Asia. The first very successful symposium was held in Calcutta in 1973. We were most pleased when Dr. Amir Muhammed, Vice Chancellor of the University of Agriculture, Lyallpur suggested that we hold a symposium on a topic of great importance to Pakistan, Genetic Control of Diversity in Plants, under the auspices of the University of Agriculture. It is our hope that this symposium will be followed by additional ones in Pakistan as well as in other countries in the Far East. Leadership is quickly developing in the hands of outstanding scientists in these countries, and we appreciate the opportunity to cooperate with them. We are especially grateful to the Natiohal Science Foundation for makingPL- 480 funds available which made this symposium possible.

Disturbances in taurine metabolism are seen in dysfunction al states as diverse as epilepsy, cardiomyopathy, Friedreich's ataxia and congestive heart failure, which combined with the antiepi1eptic and cardiotonic actions of taurine underscore the emerging clinical importance of this fascinating substance. This is the third book to appear on taurine since 1976. The last book (Taurine and Neuro1oeica1 Disorders, Raven Press, 1978) emphasized the involvement of taurine in central nervous system phenomena. These actions are further explored in this volume. In addition, nutritional aspects of taurine, particularly as these re late to development, have been increasingly recognized to be im portant parts of the taurine story. The marked emphasis placed on nutrition by a number of contributors to this volume is recognition of the meteoritic growth of this area. Are the multitudinous actions of taurine differential expres sions of a universal mechanism There is surprising unity of opinion expressed by the scientists contributing to this volume, despite their differences in viewpoint and background, as the reader, tanta lized we hope by this remark, will discover.

Taschenbuch. Condición: Neu. Neuware - In this volume, the third of our series, the emphasis has shifted from the theoretical and experimental to the more clinical and practical aspects of alcoholism. Where, in the earlier volumes, more attention was directed to animal than human studies, in this volume, almost all material deals with the human condition. The clinical manifestations of alcoholism may be divided into two major aspects, that of the disease itself and that of its complications. This separation is to some extent artificial since, in a sense, the natural history of the disease is a function of the development of certain complicating mechanisms. These mechanisms in turn either become part and parcel of the underlying condition -alcoholism-or give rise to a new set of clinical variables characterized as 'medical complications. ' At this point, the dichotomy becomes real. The disease alcoholism tends to be seen as a distinct psychosocial entity and to be treated with psychosocial techniques. The 'medical complications' are more clearly envisioned as being within the legitimate domain of medical practice and are treated by physicians who often tend to ignore the underlying alcoholism. The 'patient' is sometimes lost in between. The major thrust of this volume is an attempt to describe the mechanisms of alcoholism as they are now known, in such a way as to establish a continuum between the disease alcoholism and its 'medical complications.

This possi bility was emphasized in February 1977 in a Seminar on US energy policies at The Hartford Graduate Center by John F. O'Leary, Head of the Federal Energy Administration, who said that 'by the year 2100, --- laser fusion will be coming along, giving us a new age of choice'. Efforts in research and development were stepped up to investigate new concepts of laser ignition of controlled nuclear reactions. Here, one expects no radioactive waste from fuel. The deuterium-tritium reaction - the only one which may be possible with magnetic field confinement in tokamaks - has a highly radio active tritium ~ycle, while, in principle, laser reactions are possible with pure deuterium, hydrogen-boron or others. The worldwide progress in laser compression was not only stim ulated by the energy crisis, but also by its advancements. In our first Workshop in 1969 F. F10ux of the French Limei1 Laboratories described his experiments, which led, only one month later, to the production of fusion neutrons in such large numbers as had not been achieved up to then (see appendix of Vol. I these Proceedings).

Neuware - The impetus for the conference held at Bombannes, France in May, 1982 arose out of a Scientific Committee on Oceanic Research (SCOR) Working Group on 'Mathematical Models in Biological Oceanography'. This group was chaired by K.H. Mann and held two meetings in 1977 and 1979. At both meetings it was felt that, although reductionist modelling of marine ecosystems had achieved some successes, the future progress lay in the development of holistic ecosystem models. The members of the group (K.H. Mann, T. Platt, J.M. Colebrook, D.F. Smith, M.J.R. Fasham, J. Field, G. Radach, R.E. Ulanowicz and F. Wulff) produced a critical review of reductionist and holistic models which was published by the Unesco Press (Platt, Mann and Ulanowicz, 1981). One of the conclusions of this review was that, whether holistic or reductionist models are preferred, it is critically important to increase the scientific effort in the measurement of physiological rates for the computation of ecological fluxes. The Working Group therefore recommended that an international meeting should be organized which would attempt to bring together theoretical ecologists and biological oceanographers to assess the present and future capability for measuring ecological fluxes and incorporating these data into models. An approach was made to the Marine Sciences Panel of the NATO Science Committee who expressed an interest in funding such a meeting. They awarded a planning grant and a planning group was formed consisting of M.J.R. Fasham, M.V. Angel, T. Platt, R.E.

Taschenbuch. Condición: Neu. Neuware - This volume is the second in 'The Downstate Series of Research in Psychiatry.' It is aseries devoted to the presentation of sig nificant research with relevance for both clinicians and researchers in the multiple subfields of psychiatry. This book focuses on the interactions between psychic phenomena and physical processes as studied by evoked brain potentials. It presents material concerned with physiological and psychological unifying processes, as weIl as research concerning technology and methods of obtaining meaningful measurements. As such it is representative of biological psychiatry at its best. Thus, it represents another step in new directions in psychiatric research but not an unanticipated direction. Scientific investigation into the human psyche took an unex pected turn when Sigmund Freud in the last part of the 19th Century turned his attention from neurological concerns to those of psychol ogy. His first attempts at explanations as noted in the 'project,' included a heavy emphasis on the biological substrate of behavior.

The primary aim of this conference was to provide a forum for the leading researchers, clinicians, educators and administrators in these two fields to present a program on heart disease and cancer which included a) the major historical milestones, b) the present areas of greatest interest in research and therapy, c) the latest nutritional, molecular, and biotechnological advances, and d) a perspective on the most promising areas for future research and therapy. Scientists have long contended that research marches on the feet of methodology. Thus there are numerous examples of research fields opening secondary to methodological advances. Some examples are: 1) thin layer and gas-liquid chromatography which, along with high pressure liquid chromatography have broadened the line of advances in lipid research and 2) peR and the resultant impact on molecular biological approaches to several fields of science. The organizers of this conference thought the time was propitious for bringing together knowledge on newer aspects of molecular biological research with current advances in the two major areas of degenerative disease--coronary heart disease and cancer. Our knowledge of these 'killer diseases' has expanded greatly in the past few years and the advance has been catalyzed by use of an array of molecular biological techniques. Thanks to these, medical thinking in these areas is changing from considerations of treatment to strategies for prevention. 267 pp. Englisch.

This item is printed on demand - it takes 3-4 days longer - Neuware -The successful early adaptations of man involve a complex interplay of biological and cultural factors. There is a rapidly growing number of paleontologists and paleoanthropologists who are concerned with hominid foraging and the evolution of hunting. New techniques of paleoanthropology and taphonomy, and new information on human remains are added to the traditional approaches to the study of past human hunting and other foraging behavior. There is also a resurgence of interest in the early peopling of the New World. The present book is the result of the Ninth Annual Spring Systematics 10, 1986, in the Symposium, on the Evolution of Human Hunting, held on May Field Museum of Natural History in Chicago. We are grateful to the NSF (grant no. BNS 8519960) for partial financial support in arranging the symposium. In preparation of this volume we have received assistance from many people, particularly the reviewers of individual chapters; it is impossible to name them all. We must however single out Drs. Richard G. Klein and Glen H. Cole for their encouragement at various stages of preparation of the symposium and this volume, and for being a help to the anthropological knowledge. Zbigniew Jastrzebski assisted with the figures and Paul K. Johnson diligently typed the camera-ready copy, and patiently coordinated the endless book-making chores. 476 pp. Englisch.

This item is printed on demand - it takes 3-4 days longer - Neuware -The emergence of reaction injection molding (RIM) has been fol lowed by the industry with mounting interest. RIM technology has brought to polymer processing a new flexibility and savings in both energy and capital investment. The new developments and the number of engineers and scientists working in RIM is growing at so fast a rate that there is need for sharing information on progress in this area. This book is based on papers presented at the International Symposium on Reaction Injection Molding which was held in 1981 in Atlanta, Georgia, and was sponsored by the American Chemical Society, Division of Organic Coatings and Plastics Chemistry. The book is divided into four parts covering different areas of RIM development. The first part is devoted to the future trends of RIM develop ment in the United States and Japan. The structure-properties relationship and effects of annealing on properties of RIM elastomers are covered in the second part. New non-urethane polymers such as polyamides, polyisocyanurates and polystyrene suitable for RIM processing are discussed in the third part. In the last part the engineering and technological aspects of RIM, such as glass reinforcement, mixing, flow and moldability are covered in detail. Finally I would like to thank Mrs. Iris Glebe for typing this book and for help with editing, and K. Zielinski for his assistance v vi PREFACE in reviewing and, when necessary, correcting some of the papers. Thanks is also due to the editors of Plenum for their patience and helpfulness. 316 pp. Englisch.

This item is printed on demand - it takes 3-4 days longer - Neuware -The first edition of this text was written primarily by one of the present authors (HAS), with a chapter on instrumentation contributed by a second (NLA). The volume was well received, and to keep the text up-to-date a second edition was planned. For this second edition, a third author (WEK) was invited, whose background complemented that of the other two. Each of the authors was assigned several chapters as his primary task while the complete manuscript remained the second ary responsibility of all three. It is hoped that this approach has resulted in a work that is even more thorough than the first edition in covering the basic concepts of infrared spectroscopy. NELSON L. ALPERT WILLIAM E. KEISER HERMAN A. SZYMANSKI v PREFACE TO THE FIRST EDITION My experience with the many infrared spectroscopy institutes held at Canisius College and many discussions with both beginners and experienced practitioners in infrared spectroscopy have convinced me that there is a need for an introductory text devoted entirely to infrared spectroscopy, a text which can be utilized even by those who approach this study with only a limited background. This volume sprang from that conviction. It is intended for all who wish to use infrared spec troscopy in research - especially chemists doing structural work - in routine control work, in industrial development, or in medical appli cations or those military applications where it is employed as an analytical tool. 552 pp. Englisch.

This item is printed on demand - it takes 3-4 days longer - Neuware -Until recently, the interpretation of data obtained in seismic exploration has been based on comparatively simple representations of the Earth. The most commonly used representation for the Earthhas been a set of thick layers, each characterized by a single value for the propa gation speed of seismic waves. During the last several years, more complicated representa tions in the form of thin layers with vertical velocity gradients, as weIl as homogeneous thin layers have been considered. New methods for studying propagation speeds in a medium, particularly ultrasonic logging methods, and the results of theoretical and experimental studies of the dynamic characteristics of seismic waves have revealed that areal Earth is considerably more complicated than the simple models accepted in the past. This has led to a need for more realistic representations of the real Earth as a medium through wh ich seismic waves propagate. Because of this, tlie Department of Seismic Exploration Methods of the Institute of Physics of the Earth of the Acad emy of Sciences of the USSR has been carrying out both experimental and theoretical studies on the topic 'Selection of Physical Representations of Actual Media and the Study of the Correspond ing Wave Propagation Effects. ' Three major subdivisions have been recognized within this over all pro gram: 1. The establishment of a direct relationship between the structure of a real medium and the basic wave-propagation characteristics. 216 pp. Englisch.

Taschenbuch. Condición: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -Cryogenics is an emerging technology filled with promises. Many cryogenic systems demand the use of nonmetallics and composites for adequate or increased performance. Thermal and electrical insulations, potting for superconducting magnets' mechanical sta bility, and composite structures appear to be some of the most significant applications. Research on nonmetallics at cryogenic temperatures has not progressed to the degree of research on metals. Nor can room temperature research be extrapolated to low tempera tures; most polymers undergo a phase transformation to the glassy state below room temperature. Research by producers, for the most part, has not been prac tical, because, except for LNG applications, the market for large material sales is not imminent. There are, however, many government stimulated developmental programs. Research on nonmetallics thus is dictated by development project needs, which require studies orien ted toward prototype hardware and specific objectives. As a result, research continuity suffers. Under these conditions, periodic topical conferences on this subject are needed. Industry and uni versity studies must be encouraged. Designers and project research material specialists need to exchange experiences and data. Low temperature-oriented research groups, such as the National Bureau of Standards and the Institute for Technical Physics - Karlsruhe, must contribute by assisting with fundamentals, interpreting proj ect data, and contributing to project programs through their materials research. 460 pp. Englisch.

Special considerations in heart valve replacement, such as valve selection, reoperation, results of double valve implantation, quality of life, and the use of valved conduits are also included. Finally, long term clinical follow-up with the ST. JUDE MEDICAL® heart valve, giving 7- and 8-year data is discussed. HEART VALVE REPLACEMENT IN PEDIATRIC PATIENTS Anticoagulation Anticoagulation in children is a difficult and interesting problem. Three princi pal considerations in the use of anticoagulants are patient education, timing, and anticoagulating substance. Additional considerations are patient tolerance and compliance. Generally, the findings indicate, if pediatric patients receive anticoagulation following mechanical valve replacement, it is well accepted and results in few complications. If children are not anticoagulated, complications arise. Conflicting results regarding the efficacy of PERSANTINE® and the use of aspirin vs. COUMADIN® were reported.

Taschenbuch. Condición: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -It has often been said that the laser is a solution searching for a problem. The rapid development of laser technology over the past dozen years has led to the availability of reliable, industrially rated laser sources with a wide variety of output characteristics. This, in turn, has resulted in new laser applications as the laser becomes a familiar processing and analytical tool. The field of materials science, in particular, has become a fertile one for new laser applications. Laser annealing, alloying, cladding, and heat treating were all but unknown 10 years ago. Today, each is a separate, dynamic field of research activity with many of the early laboratory experiments resulting in the development of new industrial processing techniques using laser technology. Ten years ago, chemical processing was in its infancy awaiting, primarily, the development of reliable tunable laser sources. Now, with tunability over the entire spectrum from the vacuum ultraviolet to the far infrared, photo chemistry is undergoing revolutionary changes with several proven and many promising commercial laser processing operations as the result. The ability of laser sources to project a probing beam of light into remote or hostile environments has led to the development of a wide variety of new analytical techniques in environmental and laboratory analysis. Many of these are reviewed in this book. 480 pp. Englisch.

Professor Plesser played a central role in the research done both at the Weizmann Institute and at Argonne National Laboratories on the 'Coulomb explosion' method. His friends honored his memory by organizing a meeting in which subjects related to Plesser's interests would be discussed. Just a week be fore the conference started we were struck by another tragedy -the death of our graduate student Ms. Hana Kovner, who participated in many of the Coulomb explosion experiments at the Weizmann Institute. We would like to dedicate these proceedings to her memory as well. The goal of the workshop was to bring together chemists and physicists working on different aspects of the structural problems of small molecular en tities. The time seemed appropriate for discussing experimental and theoretical concepts, since in recent years new methods have been introduced, and a large amount of information has been accumulated on systems not studied before, like unstable molecules, ions, van der Waals molecules and clusters. The program of the workshop reflects, we believe, these new developments. The meeting was characterized by intensive discussions in which the weak nesses and strengths of new and of well established concepts were revealed. We hope that it measured up to the high standards Itzhak Plesser maintained all through his scientific life. 364 pp. Englisch.

Taschenbuch. Condición: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -The biological significance of carbohydrates in glycosyl ated biopolymers emerged from studies on viruses, microbial cells and animal tissues. Plant-related processes, a rela tive newcomer to this area of research, now offer chal lenging questions as regards the roles of glycosyl-con jugates and carbohydrate-binding proteins in such broadly based topics as pollination, fertilization, symbiosis (including nitrogen fixation), the chemical basis of morphogenesis, and the broad area of plant protection. While the impressive accomplishments on model systems, membrane-bound processes, receptor site biochemistry, and cell surface interactions fill numerous reports, reviews, and books, most of these involve biological systems other than plants. A real need exists for the present volume in which cell recognition and cell surface interactions as related to plants are examined. Contributions to this volume may be sorted into three catagories: first an overview of the structures and pro perties of glycoconjugates, then a closer look at specific systems in terms of biological function, and finally, selected examples of cell recognition and cell surface interactions as encountered in biology. To introduce the general subject, Alan Elbein reviews the structure and bio synthesis of certain glycoconjugates and examines the bio chemical basis of adherence between bacteria and eucaryotic cells. Irwin Goldstein examines the properties of plant derived lectins, in particular a group of lectins from Bandeiraea simplicifolia. The roles of several biologi cally-active complex carbohydrates in plant-related host pest relationships are examined by Peter Albersheim and his colleagues. 292 pp. Englisch.

This was the 12th conference organized by the Internatio nal School of Quantum Electronics, under the auspices of the 'Ettore Majorana' Center for Scientific Culture. This volume contains both the in vited and contributed papers presented at the conference, covering current research work in two areas: new laser sources, and laser applications. The operation of the first laser by Dr. Theodore Maiman in 1960 initia ted a decade of scientific exploration of new laser sources. This was fol lowed by the decade of the 1970s, which was characterized by 'technology push' in which the discoveries of the 1960s were seeking practical applica tion. In the 1980s we are instead seeking 'applications pull,' in which the success and rapid maturing of laser applications provides both inspiration and financial resources to stimulate additional work both on laser sources and applications. The papers presented in these Proceedings attest to the great vitali ty of research in both these areas: New Laser Sources. The papers describe current developments in ultra violet excimer lasers, X-ray lasers, and free electron lasers. These new lasers share several characteristics: each is a potentially important coher ent source; each is at a relatively short wavelength (below 1 micrometer); and each is receiving significant development attention today. 468 pp. Englisch.

Cell Analysis will cover techniques on cell separation, cell identification and classification, characterization of orga nized cellular components, functional properties of cells, and cell interactions. Applications in cell biology, immunology, genetics, toxicology, specific diseases, diagnostics and therapeutics, and other areas will be covered whenever relevant results exist.

Taschenbuch. Condición: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -This book is based on the contributions to the IFAC-Workshop 'Mass Spectro metry in Biotechnological Process Analysis and Control' held in Graz, Austria from 23 to 24 October 1986. The idea to organize this workshop and further to prepare these proceedings was stimulated by the following facts. Biotechnological processes urgently need better on-line instrumentation. Mass spectrometry (MS) offers a great potential to especially analyse gases and volatile compounds. It is, however, considered that this potential by far is not exhausted. The main reason for this is that MS often still is considered to be a very expensive technique requiring the permanent attention of a MS expert. In addition methods have not yet been developed to a user friendly state. On-line MS-methods are available to a certain extent, but need further development. To stimulate such development an interdisciplinary effort is necessary. Needs of industrial and university users and experience of physicists and instrument manufacturers have to be brought into a hopefully fruitful discussion. An introductory article describes the bioprocess background including a brief summary of the state of the art in bioprocess sensor and parameter estimation development, and the potential MS offers for bioprocess monitoring. In the first chapter on 'Instrumentation and Gas Analysis' a general overview on some developments in MS-instrumentation is given initially by Schmid. Then the presently available instrumentation for bioprocess monitoring is discussed by instrument manufacturers (Winter; Schaefer and Schultis; Bartman). 256 pp. Englisch.

This item is printed on demand - it takes 3-4 days longer - Neuware -With this proceedings of the fourth symposium on complex mixtures, we continue to revise and extend our knowledge of genetic methods for the evaluation of chemical mixtures in the environment. The early chapters of this volume are devoted to new bioassay techniques that are directly applicable to the monitoring of environments contaminated with genotoxic chemicals. Microbiological methods have been further refined to meet the special needs of atmospheric monitoring so that very small samples may now be efficiently tested. New in situ methods utilizing green plants actually avoid many of the usual difficulties of sample collection and preparation and offer special advantages in monitoring wastewater, sludges, and hazardous wastes. Insects also are being employed very effectively in the evaluation of gaseous air pollutants in controlled laboratory investigations. Increased emphasis has been placed on a comprehensive assessment of the potential of complex mixtures t9 cause various kinds of genetic damage. New assays for chromosome structural and numerical aberrations in mammalian cells in vitro have been developed and are being applied in laboratory studies. Efforts to link tests for gene mutation and cell transformation in vitro with assays for tumorigenesis in vivo are contributing to the validation of the short-term testing approach. Studies comparing in vitro and in vivo data on a coal conversion by-product, on polycyclic aromatic hydrocarbons, and on mineral fibers are reported in separate papers. Later chapters are devoted to investigations on the fractionation and biological evaluation of specific chemical components within complex mixtures. 396 pp. Englisch.

This item is printed on demand - it takes 3-4 days longer - Neuware -This volume contains the contributions to the INTERNATIONAL SUMMER INSTITUTE ON THEORETICAL PHYSICS 1980 held from September 1st to September 12th in Bad Honnef, Germany. This Institute was organized by Wuppertal University. It was the eleventh in a series of Summer Schools on particle physics carried out by German Universities. The Institute was aimed to review the present status of gauge theories in elementary particle physics, with emphasis both on the phenomenological and formal aspects. The first part of the volume covers the recent progress in the development of perturbative methods both in quantum chromodynamics (QCD) and flavor dynamics (QFD). Applications to available data from electron positron storage rings and deep inelastic scattering are discussed. The second part presents new results on classical solutions and non-perturbative methods in gauge theories and related field theories like non linear a-models. A very topical account is given on the application of Monte Carlo methods within lattice gauge theories. At present these methods appear to be the most promising technique to establish the quark confinement hypothesis within the framework of non-Abelian gauge theories. The volume is closed with a progress report on the present understanding of sup~rgravity and its relation to grand unification schemes. The lectures on Grand Unified Theories given by Dr. D. V. Nanopoulos at the Bad Honnef meeting can be found in the proceedings of the 1980 Rencontre de Moriond (Ed. J. Tran Thanh Van). 352 pp. Englisch.

The current theme is behavioral science aspects of trans portation. This topic was chosen to exemplify a problem area of practical import to which psychologists, sociologists, and other behavioral and social scientists can make and have been making notable contributions. Our volume includes papers from a variety of psychological perspec tives, including human factors, environmental psychology, and be havior modification, along with other contributions from a sociologist and a transportation engineer interested in behavioral science contribu tions to transportation. Joining us as guest editor for this volume is Peter Everett, an environmental psychologist whose area of specialty is the study of behavioral components of transportation systems. Volume 6 of our series, currently in preparation, will be devoted to behavior and the natural environment. A provisional table of contents for that volume appears on page v. Irwin Altman Joachim F.
