Taschenbuch. Condición: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -A new breed of engineer is developing in our contemporary society. These engineers are concerned with communications and computers, economics and regulation. These new engineers apply themselves to data-to its pack aging, transmission, and protection. They are data engineers. Formal curricula do not yet exist for their dedicated development. Rather they learn most of their tools 'on the job' and their roots are in computer engineering, communications engineering, and applied mathe matics. There is a need to draw relevant material together and present it so that those who wish to become data engineers can do so, for the betterment of themselves, their employer, their country, and, ultimately, the world-for we share the belief that the most effective tool for world peace and stability is neither politics nor armaments, but rather the open and timely exchange of information. This book has been written with that goal in mind. Today numerous signs encourage us to expect broader information exchange in the years to come. The movement toward a true Integrated Services Digital Network (ISDN) is perhaps the clearest of these. Also, the development offormal protocol layers reflects both a great deal of brilliance and compromise and also the desire for a common language among data engineers. 512 pp. Englisch.

This is the ninth event in a series which was initiated shortly after Corporate Research was created as a separate entity within our Company; the Symposia are held every other year. The themes to date have been: 1969 Flow Research on Blading 1971 Real-Time Control of Electric Power Systems 1973 High-Temperature Materials in Gas Turbines 1975 Nonemissive Electrooptic Displays 1977 Current Interruption in High-Voltage Networks 1979 Surges in High-Voltage Networks 1981 Semiconductor Devices for Power Conditionling 1983 Corrosion in Power Generating Equipment 1985 Computer Systems for Process Control Why have we chosen these topics At the outset we established certain selection criteria; we felt that a subject for a symposium should fulfill the following three requirements: It should characterize a part of a thoroughly scientific discipline; in other words it should describe an area of scholarly study and research. r - It should be of current interest in the sense that important results have recently been obtained and considerable research effort is presently underway in the international scientific community. - It should bear some relation to the scientific and technological activity of our Company. Let us look at the requirement 'current interest': Some of the topics on the list above have been the subject of research for several decades, some even from the - v vi FOREWORD ginning of the century. 376 pp. Englisch.

Taschenbuch. Condición: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -The past twenty five years - roughly the period from 1960 to 1985 - have been by all measures among the most exciting and challenging times of our science. The increasing sensitivity of chemical instrumentation, the introduction of the routine use of computers for data reduction and of microprocessors for instrumental control, the wide-spread utilization of lasers, and the disappearance of traditional disciplinary boundaries between scientific fields are but a few of the examples one could cite to support the introductory contention. Almost all of these developments have had their impact on the development of Mossbauer Effect Spectroscopy into a technique par excellence for the elucidation of problems in all areas of chemistry and its associated sister sciences. Indeed, because this spectroscopy is based on fundamental phenomena in nuclear physics, is described in terms of the theory of the solid state and structural chemistry, is useful in the understanding of chemical reactivity and biological phenomena, and can serve to supplement information developed by many other experimental techniques, it has provided an unparalleled opportunity for the exchange of ideas among practitioners of a very wide variety of subfields of the physical and biological sciences. The present collection of contributions is the direct result of such an interaction. 396 pp. Englisch.

This item is printed on demand - it takes 3-4 days longer - Neuware -The incidence of endometrial cancer rose sharply in the United States in the early 1970s, paralleling changes in the use of postmenopausal estrogens by American women. A sizeable body of evidence supports the role of both excessive endogenous estrogen and exogenous estrogen in the etiology of endometrial cancer. There is growing evidence that inadequate progesterone has the opposite effect, in that progesterone supplementation of postmeno pausal estrogen therapy reduces the incidence of endometrial cancer. Despite this new awareness of the hormonal role that is played in carcino ma of the endometrium, the disease still plagues the oncologist. The general approach to carcinoma of the endometrium in the United States is that of primary surgical staging. This provides the maximum amount of information to best plan postoperative radiation therapy and/or chemotherapy for these patients. In general, patients who are considered candidates for surgical staging are those with advanced disease or high-risk stage I endometrial carcinoma. High-risk endometrial carcinoma is defined as those patients with moderately differentiated lesions with deep myometrial invasion, poor ly differentiated carcinoma of the endometrium, and the high-risk histolo gies such as papillary carcinoma and clear-cell carcinomas. The surgical staging has extended in most institutions to patients with occult stage II carcinoma of the endometrium, i. e. 152 pp. Englisch.

Taschenbuch. Condición: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -The Nature of the Book This book is a text for a first course in statistical concepts and methods. It introduces the analysis of data and statistical inference and explains various methods in enough detail so that the student can apply them. Little mathematical background is required; only high school algebra is used. No mathematical proof is given in the body of the text, although algebraic demonstrations are given in appendices at the ends of some chapters. The exposition is based on logic, verbal explanations, figures, and numerical examples. The verbal and conceptual levels are higher than the mathematical leveL The concepts and methods of statistical analysis are illustrated by more than 100 interesting real-life data sets. Some examples are taken from daily life; many deal with the behavioral sciences, some with business, the health sciences, the physical sciences, and engineering. The exercises are of varying degrees of difficulty. This book is suitable for undergraduates in many majors and for grad uate students in the health sciences, behavioral sciences, and education. It has grown out of our experience over many years of teaching such courses. An earlier text by T. W. Anderson and S. L. Sclove, The Statistical Analysis of Data, had similar objectives and was of a similar nature. 740 pp. Englisch.

Taschenbuch. Condición: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -ELLP ACK is a many faceted system for solving elliptic partial differential equations. It is a forerunner of the very high level, problem solving environments or expert systems that will become common in the next decade. While it is still far removed from the goals of the future, it is also far advanced compared to the Fortran library approach in common current use. Many people will find ELLP ACK an easy way to solve simple or moderately complex elliptic problems. Others will be able to solve really hard problems by digging a little deeper into ELLP ACK. ELLP ACK is a research tool for the study of numerical methods for solving elliptic problems. Its original purpose was for the evaluation and comparison of numerical software for elliptic problems. Simple examples of this use are given in Chapters 9-11. The general conclusion is that there are many ways to solve most elliptic problems, there are large differences in their efficiency and the most common ways are often less efficient, sometimes dramatically so. 512 pp. Englisch.

Taschenbuch. Condición: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -This volume comprises the proceedings of a NATO Advanced Study Institute held in Geilo, Norway, between 4 - 14 April 1989. This Institute was the tenth in a series held at Geilo on the subject of phase transitions. It was the first to be concerned with the growing area of soft condensed matter, which is neither ordinary solids nor ordinary liquids, but somewhere in between. The Institute brought together many lecturers, students and active researchers in the field from a wide range of NATO and some non-NATO countries, with financial support principally from the NATO Scientific Affairs Division but also from Institutt for energiteknikk, the Nor wegian Research Council for Science and the Humanities (NAVF), The Nordic Institute for Theoretical Atomic Physics (NORDITA), the Norwegian Physical Society and VISTA, a reserach cooperation between the Norwegian Academy of Science and Letters and Den norske stats oljeselskap a.s (STATOIL). The organizing committee would like to thank all these contributors for their help in promoting an exciting and rewarding meeting, and in doing so are confident that they echo the appreciation also of all the participants. 50ft condensed matter is characterized by weak interactions between polyatomic constituents, by important thermal fluctuations effects, by mechanical softness and by a rich range of behaviours. The main emphasis at this Institute was on the fundamental collective physics, but prepar ation techniques and industrial applications were also considered. 404 pp. Englisch.

Taschenbuch. Condición: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -As feature dimensions of integrated circuits shrink, the associated geometrical constraints on junction depth impose severe restrictions on the thermal budget for processing such devices. Furthermore, due to the relatively low melting point of the first aluminum metallization level, such restrictions extend to the fabrication of multilevel structures that are now essential in increasing packing density of interconnect lines. The fabrication of ultra large scale integrated (ULSI) devices under thermal budget restrictions requires the reassessment of existing and the development of new microelectronic materials and processes. This book addresses three broad but interrelated areas. The first area focuses on the subject of rapid thermal processing (RTP), a technology that allows minimization of processing time while relaxing the constraints on high temperature. Initially developed to limit dopant redistribution, current applications of RTP are shown here to encompass annealing, oxidation, nitridation, silicidation, glass reflow, and contact sintering. In a second but complementary area, advances in equipment design and performance of rapid thermal processing equipment are presented in conjunction with associated issues of temperature measurement and control. Defect mechanisms are assessed together with the resulting properties of rapidly deposited and processed films. The concept of RTP integration for a full CMOS device process is also examined together with its impact on device characteristics. 456 pp. Englisch.

Taschenbuch. Condición: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -The problem of molecules interacting with metal surfaces has for a very long time been recognized to be of considerable technological as well as fundamental importance. Thus in the former category, a substantial number of important synthetic reactions for industrial purposes make use of metal surfaces as catalysts. Or again, problems of corrosion of metals are of great practical importance, such as in nuclear-reactor technology [see, for instance, my earlier articles, in: Physics Bulletin, Volume 25, p. 582, Institute of Physics, UK (1974); and in: Physics and Contemporqry Needs (Riazuddin, ed. ), Vol. 1, p. 53, Plenum Press, New York (1977)]. It is therefore of significance to strive to gain a more fundamental understand ing of the atomic, and ultimately the electronic, processes that occur when a molecule is brought into the proximity of a metal surface. The present volume focuses mainly on the theory and concepts involved; however, it is intended for readers in chemistry, physics, and materials science who are not specialists in theory but nevertheless wish to learn more about this truly interdisciplinary area of theoretical science. The aim of the book is to present the way in which valence theory can be synthesized with the understanding of metals that has been gained over the last half century or so. While advanced theory has at times been necessary, is largely presented in an extensive set of Appendixes. 300 pp. Englisch.

Taschenbuch. Condición: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -We present here the transcripts of lectures and talks which were delivered at the NATO ADVANCED STUDY INSTITUTE 'Electronic Structure of Complex Systems' held at the State University of Ghent, Belgium during the period July 12-23, 1982. The aim of these lectures was to highlight some of the current progress in our understanding of the electronic structure of com plex systems. A massive leap forward is obtained in bandstructure calculations with the advent of linear methods. The bandtheory also profitted tremendously from the recent developments in the density functional theories for the properties of the interacting electron gas in the presence of an external field of ions. The means of per forming fast bandstructure calculations and the confidence in the underlying potential functions have led in the past five years or so to a wealth of investigations into the electronic properties of elemental solids and compounds. The study of the trends of the electronic structure through families of materials provided invalu able insights for the prediction of new materials. The detailed study of the electronic structure of specific solids was not neglected and our present knowledge of d- and f-metals and metal hydrides was reviewed. For those systems we also investi gated the accuracy of the one electron potentials in fine detail and we complemented this with the study of small clusters of atoms where our calculations are amenable to comparison with the frontiers of quantum chemistry calculations. 816 pp. Englisch.

Taschenbuch. Condición: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -Our purpose in writing this book was two-fold. First, we wanted to compile a chronology of the research in the field of mixed-mode simulation over the last ten to fifteen years. A substantial amount of work was done during this period of time but most of it was published in archival form in Masters theses and Ph. D. dissertations. Since the interest in mixed-mode simulation is growing, and a thorough review of the state-of-the-art in the area was not readily available, we thought it appropriate to publish the information in the form of a book. Secondly, we wanted to provide enough information to the reader so that a proto type mixed-mode simulator could be developed using the algorithms in this book. The SPLICE family of programs is based on the algorithms and techniques described in this book and so it can also serve as docu mentation for these programs. ACKNOWLEDGEMENTS The authors would like to dedicate this book to Prof. D. O. Peder son for inspiring this research work and for providing many years of support and encouragement The authors enjoyed many fruitful discus sions and collaborations with Jim Kleckner, Young Kim, Alberto Sangiovanni-Vincentelli, and Jacob White, and we thank them for their contributions. We also thank the countless others who participated in the research work and read early versions of this book. Lillian Beck provided many useful suggestions to improve the manuscript. Yun cheng Ju did the artwork for the illustrations. 228 pp. Englisch.

Taschenbuch. Condición: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -It would be difficult to think of a more important field of study in medicine than the interaction of cells with natural and foreign surfaces, but it is rare for those in the practice of medicine and surgery to get together with the basic scientists to discuss what they know about it, so that ground of common interest can be explored. Perhaps the symposium should have been entitled 'Interactions between those interested in cell surfaces --- ' because it is here that the chief value of such meetings must lie. Even a brief perusal of this volume shows just how far advanced thought and work are on some facets of the topic. Some of the most pressing problems in medicine are those of tumour spread and of thrombosis of blood vessels where surface phenomena are of paramount importance. Our understanding is still very limited but, as the symposium illustrated, the answers are only to be found by study at fundamental levels, the work gaining direction and point from interaction with surgeons and others concerned with the actual disease states. 348 pp. Englisch.

Taschenbuch. Condición: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -Part of a two volume set based on a recent IMA program of the same name. The goal of the program and these books is to develop a community of statistical and other scientists kept up-to-date on developments in this quickly evolving and interdisciplinary field. Consequently, these books present recent material by distinguished researchers. Topics discussed in Part I include nonlinear and non- Gaussian models and processes (higher order moments and spectra, nonlinear systems, applications in astronomy, geophysics, engineering, and simulation) and the interaction of time series analysis and statistics (information model identification, categorical valued time series, nonparametric and semiparametric methods). Self-similar processes and long-range dependence (time series with long memory, fractals, 1/f noise, stable noise) and time series research common to engineers and economists (modeling of multivariate and possibly non-stationary time series, state space and adaptive methods) are discussed in Part II . 276 pp. Englisch.

This item is printed on demand - it takes 3-4 days longer - Neuware -This book contains lecture notes and invited contributions presented at the NATO Advanced Study Institute and EPS Liquid State Conference on PHYSICOCHEMICAL HYDRODYNAMICS-PCH: INTERFACIAL PHENOMENA that were held July 1-15, 1986, in LA RABIDA (Huelva) SPAIN. Although we are aware of the difficulty in organizing the contents due to the broad and multidisciplinary aspects of PCH-Interfacial Phenomena, we have tried to accomodate papers by topics and have not followed the order in the presentation at the meetings. There is also no distinction between the ASI notes and Conference papers. We have done our best to offer a coverage as complete as possible of the field. However, we had difficulties coming from the fact that some authors were so busy that either did not find time to submit their contribution or did not have time to write a comprehensive paper. We also had to cope with very late arrivals, postdeadline valuable contributions that we felt had to be included here. Our gratitude goes to the NATO Scientific Affairs Division for its economic support and to the EPS Liquid State Committee for its sponsorship.

Taschenbuch. Condición: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -The author has organized basic, core information on the diagnosis, treatment and prevention of chemical dependence into a readily understandable format. His approach teaches the physician what steps to take from a practical point of view: how to prevent addiction in the first place, how to diagnose the condition, how to aid the family get the addict into treatment, and how to increase the chances of long-term recovery. The book is divided into three sections. The first section covers basic definitions and concepts. The second section describes the pharmacology of the various psychoactive substances: depressants, opioids, stimulants, cannabinoids, hallucinogens, phencyclidines, and inhalants. The third section discusses chemical dependence in special groups: women, adolescents, the elderly, ethnic minorities, dual diagnosis patients, HIV- positive patients, and impaired physicians. 388 pp. Englisch.

Taschenbuch. Condición: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -InJuly 1982 the first Dartmouth workshop on the corpus callosum took place. A nucleus of basic and clinical scientists was convened to give progress reports of their work on the corpus callosum. This text was subsequently compiled by the various participants from these reports modified by a stimulating cross fertilization of ideas and subsequent studies. Four and one-half decades have intervened since Van Wagenen first sectioned the corpus callosum for epilepsy (Van Wagenen and Herren, 1940) and Erickson (1940) demonstrated that the corpus callosum is the major route for generalization of experimentally induced focal cortical epilepsy. During the succeeding 45 years a handful of clinicians has pursued these leads to confirm the therapeutic value of callosotomy for some types of medically intractable generalized epilepsy. Parallel experimental studies with a number of epilepsy models have indicated that the corpus callosum is indeed the major route for seizure generalization, that the brainstem is a secondary and more resistant pathway for seizure generalization, and that most if not all epileptic seizures originate from the cerbral cortex. The unexpected clinical finding that even partial (focal) seizure incidence is modified by callosotomy now has been demonstrated in the laboratory. The various contributors to the clinical and experimental epilepsy sections of this volume have been seminal in these elucidations, as will be evident from their chapters. The section on the development, anatomy, and physiology of the corpus callosum demonstrates that these basic areas of study have not been neglected. 556 pp. Englisch.

Taschenbuch. Condición: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -It is estimated that the functionally significant body of knowledge for a given medical specialty changes radically every 8 years. New special ties and 'sub-specialization' are occurring at approximately an equal rate. Historically, established journals have not been able either to absorb this increase in publishable material or to extend their reader ship to the new specialists. International and national meetings, sympo sia and seminars, workshops, and newsletters successfully bring to the attention of physicians within developing specialties wh at is occur ring, but generally only in demonstration form without providing historical perspective, pathoanatomical correlates, or extensive discus sion. Page and time limitations oblige the authors to present only the essence of their material. Pediatric neurosurgery is an example of a specialty that has devel oped during the past 15 years. Over this period neurosurgeons have obtained special training in pediatric neurosurgery and then dedicated themselves primarily to its practice. Centers, Chairs, and educational programs have been established as groups of neurosurgeons in different countries throughout the world organized themselves respectively into national and international societies for pediatric neurosurgery. These events were both preceded and followed by specialized courses, national and international journals, and ever-increasing clinical and invest igative studies into all aspects of surgically treatable diseases of the child's nervous system. 272 pp. Englisch.

This item is printed on demand - it takes 3-4 days longer - Neuware -The interface between the user of a computer-based information system and the system itself has been evolving at a rapid rate. The use of a video screen, with its color and graphics capabilities, has been one factor in this evolution. The development of light pens, mice, and other screen image manipulation devices has been another. With these capabilities has come a natural desire to find more effective ways to make use of them. In particular, much work has gone into the development of interface systems that add visual elements such as icons and graphics to text. The desire to use these visual elements effectively in communication between the user and the system has resulted in a healthy competition of ideas and discussion of the principles governing the development and use of such elements. The present volume chronicles some of the more significant ideas that have recently been presented. The first volume in this series on the subject [Visual Languages (Chang, Ichikawa, and Ligomenides, eds. ), Plenum, 1986] covered work done in the early days of the field of visual languages. Here we represent ideas that have grown out of that early work, arranged in six sections: Theory, Design Systems, Visual Programming, Algorithm Animation, Simulation Animation, and Applications. I THEORY Fundamental to the concept of visual languages is the convIctIOn that diagrams and other visual representations can aid understanding and communication of ideas. We begin this volume with a chapter by Fanya S. 368 pp. Englisch.

The accurate descrip tionofrelativisticeffectsinheavyatomshaslongbeenrecognizedasoneof the central problems ofatomic physics. Contemporary relativistic atomic structure calculations can be performed almost routinely. Recent years have seen agrowinginterestin thestudyoftheeffects ofrelativityon the structureofmolecules. Even for molecularsystemscontainingatoms from thesecondrowoftheperiodictable theenergyassociatedwith relativistic effects is often larger than that arising from electron correlation. For moleculescontainingheavieratoms relativistic effects become increasingly important,andforsystemscontainingveryheavyatomsrelativityisknown todominatemanychemicalproperties. In this volum~, one of the pioneers of relativistic atomic structure calculations,Ian P. Grant,providesadetailedsurveyofthecomputational techniquesemployedincontemporarystudiesoftheeffectsofrelativityon atomicstructure. Thisisanareaofresearchinwhichcalculationscanoften lead to a particularly impressive degreeofagreement between theoryand experiment. Furthermore, theseatomicstudies haveprovided manyofthe foundations of a fully relativistic quantum chemistry. However, the spherical symmetry ofatoms allows significantsimplificationsto bemade in their quantum mechanical treatment, simplifications which are not possibleinstudiesofmolecules. Inparticular, as is wellknown from non relativistictheoriesofmolecularelectronicstructure,itisalmostobligatory to invoke the algebraic approximation in molecular work and use finite basis set expansions. The problem of describing relativistic effects in molecules is addressed in Chapter2 by Stephen Wilson. This chapter is devotedtoab initiorelativisticmolecularstructurecalculationsinwhichall electrons are explicitly considered. The problem of induding relativistic effects in molecular studies is also addressed in Chapters3 and 4. In Chapter 3, Odd Gropen describes the use of relativistic effective core ix x Preface potentials in calculations on molecular systems involving heavy atoms. This approach can lead to more tractable algorithms than the methods described in Chapter2 and thus significantly extends the range of applications. The use of semiempirical methods has yielded a wealth of informationabouttheinfluenceofrelativityonthechemistryoftheheavier elements. Thisimportantarea is reviewed inChapter4 by Pekka Pyykk6.

This item is printed on demand - it takes 3-4 days longer - Neuware -This book is a collection of invited contributions, each reflec ting an area of medicine in which computing techniques have been successfully applied; but why the title From a control system point of view the aim of clinical medicine is to recognise the deviation of a patient from the space of normality, and to propel and steer the patient along a trajectory back to that space. Acquiring and main taining the knowledge and skills of this process is the function of medicine. The first chapter expands on this view. Subsequent chapters written by experts in their respective areas cover a fair range of application. All give considerable insight as to the ways in which the control system approach, facilitated by computational tools, can be of value when applied to clinical problems. The idea for this book arose naturally out of a symposium held at the University of Sussex, Brighton, England, on 'Control System Concepts and Approaches in Clinical Medicine' in April, 1982, spon sored by the Institute of Measurement and Control and co-sponsored by the Institution of Electrical Engineers and the Royal Society of Medicine. It is not, however, a 'proceedings' of this meeting but rather a collection of essays that reflect developing areas in which many have particular interest. We think the volume is timely and hope that the work described will be an encouragement for others. 276 pp. Englisch.

This item is printed on demand - it takes 3-4 days longer - Neuware -The treatment of psychopathology in children has been a centerpiece of the overall field of problem behaviors in children. Therefore, a considerable number of data have been accumulated, particularly in recent years. These efforts have expanded at such a rate as to result in the publication of several new journals, such as the Journal of Clinical Child Psychology and Education and Treatment of Children. Similarly, many standard general clinical journals have begun to de vote more attention to children. Despite these efforts, few books have emerged that are devoted directly and specifically to treatment in childhood psychopath ology. This volume's scope is broad in that it reviews not only behavior therapy, but also the rapidly expanding efforts in psychopathology and traditional psy chotherapy, and at an advanced level. It is designed to provide an in-depth scholarly review of the empirical evidence, including an overview and analysis of the available techniques, their effectiveness, and the limitations and complica tions arising from the use of these treatment methods with the full range of psychopathology displayed by children. Many nationally and internationally recognized experts have agreed to contribute chapters to this book, and we hope that what has emerged is an up-to-date and authoritative volume. 616 pp. Englisch.

The overall aim of the developing frontiers series is to bring critical examinations of recent advances in assessment to clinicians, researchers, university teachers, and graduate students, and thus to help them to keep abreast of an important and rapidly expanding field of psychology. This aim of course cannot be fulfilled in a single volume, but it can be met, at least to a large degree, in a continuing series. In this context we encourage those readers who are pleased with the offerings in this volume to consult appropriate chapters in earlier volumes of the series. The term psychological assessment, as used in this series, encom passes all of the various techniques - tests, rating scales, interview schedules, surveys, direct observational methods, and psychophysiol ogical procedures - that are employed in scientifically based practice and research to provide an improved understanding of individual per sons, groups, or environmental settings. Thus, the whole field of assess ment is taken as the proper area of concern for the series. This includes both what are sometimes called traditional assessment and behavioral assessment, as well as approaches not typically classed in either of these categories. 332 pp. Englisch.

This item is printed on demand - it takes 3-4 days longer - Neuware -This volume is concerned with the nature of new manufacturing technologies, such as CAD/CAM and robotics, as well as ap propriate methodologies for evaluating whether such technologies are financially and organizationally viable in particular contexts. The chapters included here were commissioned as papers for presen tation at The Wharton Conference on Productivity, Technology, and Organizational Innovation, which took place in Philadelphia on December 8 and 9 of 1983. The conference was sponsored by The University of Pennsylvania's Center for the Study of Organizational Innovation. There has been a surge of interest in the area of manufacturing over the past ten years as managers have come to realize that the operations function is critical to remaining competitive. New status has been given to factory and operations managers. New programs revitalizing manufacturing and distribution have been introduced in organizations. Corporate strategy is now explicitly considering operations and manufacturing functions. And the curricula of leading business schools are reflecting the rapidly advancing research on technology management and manufacturing operations. In spite of these important signs of progress, we are clearly just at the beginning of understanding the issues involved here. The present volume provides a state-of-the-art review of the realities of technology management and manufacturing strategy. As described in the Editor's Introduction, we address four topics: The Nature of New Manufacturing Technology, Innovation and Manufacturing Strategy, Productivity Management, and Technology Management and Organ ization. These issues are clearly very important themes for U.S. 348 pp. Englisch.

Concepts and methodologies are ever changing. Also, current research in tumor immunology promises to offer breakthroughs in the future. Important is the need to communicate to the right people the exact role of immunodiagnostic methods and immunolog ical intervention in cancer prevention and treatment. The role of immuno therapy in combination with conventional modalities of treatment needs in its proper perspective. Oncogene, interferon, lympho to be understood kines, monoclonal antibodies, natural killer cells, platelet-mediated cyto toxicity of antibody-coated target cells, suppressor cells, platelet-derived factors, plasma-blocking factors, control of suppressor cell function, ab rogation of plasma-blocking factors, etc. , are some of the areas that are continually advancing. Progress in these areas will have implication in cancer therapy. Further, it is already understood that if immunocompe tence of the host can be maintained at a reasonably good level, there exists the potential to increase the therapeutic indexes of conventional modalities of treatment. This series will attempt to present updated infor mation in all these areas based on contributed and solicited articles. P. K. 244 pp. Englisch.

The intention of this series of workshops is to promote exchange of ideas and data between scientists and clinicians whose interests span molecular and cell biology, development and differentiation, oncology, and genetic and developmental pathologies. It is hoped that such interdisciplinary discussions may give rise to fruitful insights. The meetings are structured to give ample time for discussion after each formal presentation and culminate in a session of general discussion which is reported at the end of the volume of proceedings. We are very grateful to the participants, all of whom participated in the discussion and whose contributions were essential to the success of the meeting. Novel ideas were often put forward and explored thoroughly from different angles. We normally expect to achieve quite rapid publication of the proceedings of the meeting and are grateful to authors who produced typescripts of their contributions expeditiously, but, as may sometimes be the case with multi-author works, some contributors had difficulty in meeting schedules for submitting manuscripts or corrections of the text of the discussion, and in one case we have been unable to publish any record of the contribution. Our committment to the publication of the discussion, allowing participants to make corrections to the transcript of the session, such as insertion of references and clarification of oral contributions, has also imposed some delay. 404 pp. Englisch.
