Taschenbuch. Condition: Neu. Neuware -Despite an enormous investment of effort throughout the world, cancer is still a major barrier to human longevity. Cancer deaths are estimated to be more than five million globally. Currently responsible for about 20% of all deaths in developed coun tries, the burden of cancer is steadily increasing in the developing world, following the control of malnutrition and infectious and parasitic diseases. Deeply impressed by the report of the Symposium on Geographic Pathology and Demography of Cancer held at Oxford in 1950, and through his preliminary work on cancer mortality statistics in Japan, Professor M. Segi decided to devote his life to the fight against cancer by establishing worldwide comparative cancer statistics-one of the landmarks in cancer studies and in cancer prevention strategies. He and his associates published six volumes of Cancer Mortality in 24 Countries with reliable mortality statistics covering 1950-1967, using the world population which he had derived as a standard. These publications rapidly became standard works of reference on the subject throughout the world. Professor Segi was a pioneer of cancer epidemiology in Japan. He cleaved a path through the jungle of cancer using epidemiological methods. By promoting cancer studies, he overcame the poor understanding of malignant disease which existed after World War II, when cancer mortality rates were still low.

Taschenbuch. Condition: Neu. Neuware -This volume of essays grew out of a symposium organized by Judith Hoch-Smith and Anita Spring for the 1974 American Anthropological Association meetings in Mexico City. The two-part symposium was enti tled 'Women in Ritual and Symbolic Systems: I. Midwives, Madonnas, and Mediums; ll. Prostitutes, Witches, and Androgynes. ' The sym posium participants were asked to explore theological, ritual, and sym bolic aspects-both positive and negative-of the feminine cultural do main, using ethnographic materials with which they were familiar. The resulting papers have been revised, edited, and gathered together in Women in Ritual and Symbolic Roles. The theoretical importance of these papers for the study of women's participation in culture and society rests on the assumption that reli gious ideas are paramount forces in social life, that relationships be tween the sexes, the nature of female sexuality, and the social and cul tural roles of women are in large part defined by religious ideas. That this proposition remains valid long after religion itself has ceased to be a living truth in the lives of many people can be seen from the tenacious ness of Judeo-Christian ideas about women in the contemporary West ern world. Both the expansion of life options for women and the creation of more positive cultural images of the female are intimately related to changes in the my tho-symbolic portraits that people carry around in their heads. These portraits are almost exclusively constructed from mythological and religious conceptions inherent in all facets of culture.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 308 pp. Englisch.

Taschenbuch. Condition: Neu. Neuware - Three articles make up Volume 10 of Methods in Membrane Biology. In the first of these, Papahadjopoulos, Poste, and Vail extensively review much of the available data on the fusion of natural membranes, model membranes (liposomes), and natural membranes with liposomes. The authors are led by their review of the experimental methods and their interpretations of the results obtained to a general theory of membrane fusion which they believe is applicable to all systems that have been studied. Arguing that although protein and carbohydrate may serve, in some cases, to bring membranes into sufficiently close proximity for fusion to occur and, in other cases, to remove peripheral and integral proteins from the regions that are to undergo fusion, the authors conclude that membrane fusion per se is solely a property of the lipid bilayer. In their view, all the experimental observations to date can be subsumed under a unifying hypothesis in which membrane fusion is the result of a phase separation in one-half of the membrane bilayer brought about by the interaction - of calcium ions with acidic phospholipids, mostly phosphatidylserine. Where half-membranes already contain sufficient acidic phospholipids, a local increase in calcium ion concentration may suffice to induce fusion (examples might include exocytosis and fusion of intracellular membrane systems). In other cases, natural or experimentally induced events preceding fusion might be necessary to increase the local concentration of the acidic phospholipids in the half-membrane (virus-or fusogenic agent-induced cell-to-cell fusion, or endocytosis, for example).

Taschenbuch. Condition: Neu. Neuware - Advances in Clinical Child Psychology is. a serial publication designed to bring together original summaries of the most important new develop ments in the field of clinical child psychology and its related disciplines. Each chapter is written by a key figure in an innovative area of research or by an individual who is particularly well qualified to comment on a topic of major contemporary importance. These chapters provide con venient, concise explorations of empirical and clinical advances in the field. In Volume 6, the chapters reflect the changing nature of research on the disorders of children. Since the beginning of this series, increasing amounts of innovative and promising research have focused on the classification, etiology, and development of childhood psychopathol ogy. This volume contains chapters on the classification of autism, the nature of sexual abuse, the development of social deficiencies and affec tion, and the important variables of maternal depression, infant-child interactions, sibling interactions, and early temperament. This volume also highlights another significant trend in clinical child psychology-its increasing rapprochement with developmental psychology. A chapter on the importance of cognitive development in dictating child interview strategies is an important example of this trend. We appreciate the roles played by the advisory editors in suggesting excellent topics and thoughtfully editing the chapters. As always, our strongest thanks go to the volume's authors for their outstanding contributions.

Taschenbuch. Condition: Neu. Neuware - This is the third volume in the series of books based on the Annual Merseyside Course in Clinical Psychology. In common with its predecessors its aim is to present a number of topics of interest to practitioners, researchers, trainers and trainees in the field, with the intent not only to inform but variously also to question and to guide further enquiry. Selection for this volume has taken a somewhat different stance to the previous two. Whereas in former volumes an attempt has been made to cover standard areas of general and scientific interest to psychologists and others in related professions, such as anorexia nervosa, forensic issues, long term care, mental handicap, community psychology, anxiety and de pression, in this one issues which are of equal relevance but not necessarily of equal prominence in psychological texts, are included. We have not, however, neglected those areas more readily recognized as of major clinical import which are being progressively covered in this series. This year we have the section 'Bereavement and the Care of the Dying'. Although for many this may not be a main focus, it is a subject that few helpers do not encounter either directly or indirectly with their clients. It would be impossible for this subject to not reflect the most human side of the caring professions, and it is perhaps in this field that the objective/subjective dilemma of the clinician can be seen in its most acute form.

This workshop is the second to be organized on gas-phase applications of Raman scattering. Both Raman workshops were supported by Project SQUID, ONR, and the Air Force Aero Propulsion Laboratory, Wright-Patterson Air Force Base. The first Raman Workshop was held at the AVCO Everett Research Laboratory, Everett, Massachusetts, with their co-sponsorship in January 1972 under the chairmanship of D. A. Leonard. The present meeting was co-sponsored by the General Electric Research and Development Center, and held at their facility in Schenectady, New York. We are grateful to Project SQUID, AFAPL, and GE for their generous financial support of this Workshop, and to Project SQUID for underwriting the publication costs of the Proceedings. As is always the case for successful meetings, many people contributed substantially to the organization and execution of this workshop. Professor Robert Goulard supported, aided, and encouraged us in the most helpful ways, and we are indebted to him. We received further valuable support and assistance from Dr. Ralph Roberts, Director, and Mr. James R. Patton, Jr., of the Power Branch, Office of Naval Research; from Dr. William H.

Taschenbuch. Condition: Neu. Neuware - Models & Methods for Project Selection systematically examines in this book treatment the latest work in the field of project selection modeling. The models presented are drawn from mathematical programming, decision theory, and finance. These models are examined in two categorical streams: the management science stream and the financial model stream. The book describes the assumptions and limitations of each model and provides appropriate solution methodologies. Its organization follows three main themes: \*Criteria for Choice: Chapters 1-3 investigate the effect of the choice of optimization criteria on the results of the portfolio optimization problem. \*Risk and Uncertainty: Chapters 4-7 deal with uncertainty in the project selection problem. \*Non-Linearity and Interdependence: These chapters deal with problems of non-linearity and interdependence as they arise in the project selection problem.Chapters 8, 9 and 10 present solution methodologies, which can be used to solve these most general project selection models.

Taschenbuch. Condition: Neu. Neuware - Sociobiology is the play of the season. Its success is mellsured by its immense popularity and perhaps by the controversy it has generated as well. Unfortunately, neither its popularity nor the resulting controversy seems likely to assure progress toward understanding sociobiological issues. The play has too many actors and, it seems, the casting has been poor; the players are unable to maintain their roles. At center stage, of course, is E. O. Wilson and his monumental opus Sociobiology. 1 In the wings, and making periodic entrances, are an assort ment of brilliant, committed, and aggressive adversaries. On cue, one of them steps out and decries the self-fulfilling nature of sociobiological prophesies. The arguments of the adversaries are varied. They warn that if all nonhuman primate societies tolerate aggression and man is also a pri mate, then aggression may come to be considered 'normal' and therefore acceptable. Their dire warnings may also have real impact on policy, alter ing, for example, a research program intended to examine longitudinally the relation between a supernumerary chromosome and certain behavioral disorders. The rationale is that since the afflicted infants would have to be identified and the study obviously does assume that psychopathology is linked to the chromosome aberration, the attitudes of the child's parents could well contribute to abnormal behavior that might otherwise not appear.

Taschenbuch. Condition: Neu. Neuware - This is not a textbook nor an encyclopedia; rather, it is a collection of papers representing a variety of points of view on contemporary is sues, controversies, and questions about female sexual development. The editor has a point of view, not a point of view as to which of the various authors' positions presented in this book is correct, or even the most useful, but a point of view about the format of such a book; namely, that the definitive answers, and the experts who will provide them, are not yet identified. Therefore, many voices should be heard from different areas of expertise, training, experience, and back ground. Inevitably there are contradictions and disagreements. There should be. Several authors who were asked to provide short discus sions for papers found themselves unable to answer in less than an ad ditional paper. The editor welcomed this response. This is an area full of ancient myths, new discoveries, and alternate perspectives. It is hoped that the book reflects these ambiguities and controversies and that it will stimulate as many questions as it provides answers. You will find represented in this volume, and its forthcoming companion volume on women's sexual experience, authors not gener ally found together between the covers. When useful and where pos sible, a discussion or an addendum to a paper has been included by an author who approaches the subject from a different base of infor mation or experience.

Taschenbuch. Condition: Neu. Neuware - Volume 4 of Advances in Nutritional Research reflects the increased importance that recently has been attached to nutrition in many fields of clinical medicine. This heightened interest in nutrition stems from the demonstration that the intake of specific nutrients may have far-reaching consequences, not only for normal metabolism, but also for metabolic processes affecting clinical or subclinical disease. Conversely, many disease states have been shown to have previously unrecognized effects on nutrient function and metabolism. In addition to topics of obvious relevance to human clinical nutrition, this volume contains chapters dealing with the nutrition of cells grown in culture and of species that may provide insights into nutritional disorders of man. To gether with its predecessors, Volume 4 provides graduate students and estab lished investigators with authoritative accounts of the status of research on a range of topics of current interest in experimental and clinical nutrition. vii Contents Chapter 1.

Taschenbuch. Condition: Neu. Neuware - Since the appearance of the first two volumes of Modern Fluorescence Spectroscopy in 1976, important advances continue to be made in both the techniques and applications of molecular luminescence. In terms of 'hardware,' it is only recently that the application of laser excitation to molecular fluorometry has become feasible under conditions that are analy tically realistic. The improvements that can be effected in sensitivity, analy tical selectivity, and ability to handle 'difficult' samples by laser fluorometry have only begun to be exploited. Likewise, time-resolved fluorometry has received widespread use in fundamental studies (a sizable number of which deal with biological systems), but has as of yet received relatively little analytical utilization. The use of electronic array detectors offers the promise of obtaining luminescence spectra more rapidly, and perhaps ultimately with greater sensitivity, than is possible by the use of scanning instruments equipped with conventional detectors. The increasing capabilities of microcomputers and the increasing sophistication of 'smart' spectroscopic instrumentation signify that much more efficient acquisition and use can now be achieved of the information contained in the 'excitation-emission matrix' inherent in the luminescence phenomenon.

Taschenbuch. Condition: Neu. Neuware - The application of the Fourier transform is being seen to an increasing extent in all branches of chemistry, but it is in the area of chemical analysis that the greatest activity is taking place. Fourier transform infrared and nuclear magnetic resonance spectrometry are already routine methods for obtaining high-sensitivity IR and NMR spectra. Analogous methods are now being developed for mass spectrometry (Fourier transform ion cyclo tron resonance spectrometry) and microwave spectroscopy, and Fourier transform techniques have been successfully applied in several areas of electrochemistry. In addition the fast Fourier transform algorithm has been used for smoothing, interpolation, and more efficient storage of data, and has been studied as a potential method for more efficient identification of samples using pattern recognition techniques. Linear transforms have also been shown to be useful in analytical chemistry. Probably the most important of these is the Hadamard transform, which has been applied in alternative methods for obtaining IR and NMR data at high sensitivity. Even though measurements involving this algorithm will probably not be applied as universally as their Fourier transform ana logs, in the area of pattern recognition application of the Hadamard trans form will in all probability prove more important than application of the Fourier transform.

Taschenbuch. Condition: Neu. Neuware - Volume 5 of this series continues its coverage of currently active re search fields in ornithology. Because an editor can never be a disin terested observer of his or her own editorial efforts, any claim for su periority of this volume is not without conflict of interest. Even so, Volume 5 has certain merits that even a parent should acknowledge, and I find the current chapters not merely timely and authoritative but compelling in their demand for a reader's attention. Wolfgang and Roswitha Wiltschko provide a perceptive review of magnetic orientation in birds, a piece dedicated to Fritz Merkel, the pioneer in studies of magnetic orientation. Sergei Kharitonov and Doug las Siegel-Causey are concerned with the behavioral ecology of seabird coloniality, emphasizing their field experiences in the USSR and the United States. Ted Miller examines the application of studies of bird behavior to comparative biology, pursuing the interface of behavior and evolutionary biology adumbrated by Konrad Lorenz in the 1930s. Jeremy Raynor gives us a summary of the work over the past decade on bird flight, which is not, by turns, as complex or as simple as we had formerly believed. Carrol Henderson describes recent develop ments in nongame bird conservation, based on his pioneering work in the State of Minnesota. Alan Kamil discusses optimal experimental design for research in ornithology, a field in which experimental work is frequently difficult to pursue.

Taschenbuch. Condition: Neu. Neuware - The proceedings of a workshop conference are presented in this volume entitled Hypothalamic Peptide Hormones and Pituitary Regulation. The workshop was held in Wilson Hall on the campus of the National Institutes of Health, Bethesda, Maryland, during the days of November 1-2, 1976, and is the most recent of three symposia on neuroendocrinology that have been sponsored by the National Institutes of Health. The first one was held on December 6 - 8, 1961, in the New Everglades Hotel at Miami, Florida. During the first meeting, much emphasis was given to the anatomical and physiological basis for the fledgling science of neuroendocrinology. The proceedings of that symposium were published under the title of Advances in Neuroendocrinology, A. V. Nalbandov (ed. ), University of Illinois Press, Urbana, Illinois, 1963. The second workshop was held on January 8 -11, 1969, in the Arizona Inn at Tucson, Arizona, and was unique in several respects. It was evident to the participants that definitive identification and the determination of the chemical structure of at least one hypothalamic releasing factor was at hand (see Workshop Conference on Bioassay and Chemistry of the Hypophysio tropic Hormones of the Hypothalamus: ~Critical Evaluatioi'i':-J. Meites, ed. , The Williams and Wilkins Co. , Baltimore, Maryland, 1970). Much of what was presented at the second workshop was dedicated to methods of bioassay of the various releasing factors.

Taschenbuch. Condition: Neu. Neuware - This volume contains the edited transcript of an interdisci plinary colloquium held at Totts Gap Medical Research Laboratories, Bangor, Pennsylvania on October 12-14, 1983 under the sponsorship of the Muscular Dystrophy Association. The aim was to illuminate the pathogenic mechanism of Duchenne Muscular Dystrophy through a synthesis of available data on gene expression in muscle. In the informal give and take ot the collo quium, the participants found themselves engaged in mutual education and enlightenment as they attempted to put together what is known and to highlight what is not known about the subject. Significant research into muscle as a tissue and muscle disease began only about 50 years ago although the description of muscular dystrophy by Guillaume Benjamin Amand Duchenne de Boulogne had been published in 1862. By 1943 it was clear that Duchenne muscular dystrophy was an X-linked genetic disorder. Up to the present, however, the offending gene has not been identified although its location on the short arm of the X chromosome has been approximately determined. The gene product associated with the initial disturbance in skeletal muscle has also remained elusive up to now. Moreover, investigations into the mechanisms of the muscle degeneration have been hampered by ignorance of the fundamental phenotypic expression of the genetic disorder.

Taschenbuch. Condition: Neu. Neuware - The ontogeny of lymphoid cells seems the most appropriate place to start. The early events in T and B cell ontogeny are still confusing. There seems to be no agreement on the data and on the semantics of the question of progenitor vs. stem cells. Nevertheless, we are beginning to understand more about progenitor cells which are committed to particular cell lines, and about stem cells in the sense of having almost unlimited capability of giving rise to undifferentiated progeny. An important future development will be to determine the nature of the substances that attract stem cells and which are produced by specialized thymus epithelium, and perhaps by the bursa. The way stem cells recognize these signals is an important question to answer. Not predictable from mammalian models has been the observation that there is a lack of cells called into the bursa even before the signal for entry of stem cells has been shut off. A likely model suggested that after a certain point in development there were no longer any cells capable of migrating into the bursa and becoming B cells. A fascinating possibility is the suggestion that a cell comes into the bursa, is not committed, then can still wander into the thymus. This cell does not appear to have B cell characteris tics; that is, immunoglobulin is not expressed on its surface.

Taschenbuch. Condition: Neu. Neuware - Identified Neurons and Behavior of Arthropods presents for the larger audience the papers delivered at a symposium of the same title. I organized this symposium so that a few of the many who owe him a great scientific debt could honor Professor C. A. G. (Kees) Wiersma upon his attaining the age of 70 and retiring from the California Institute of Technology. Everyone of the participants publicly acknowledged his debt to Kees Wiersma, but in a sense there was no need to do so, because the research reported spoke for itself. Seldom in a rapidly developing branch of modem science has all of the recent progress so clearly stemmed from the pioneering work of a single figure. But in this subject, the role of identified nerve cells in determining behavior, Wiersma stood virtually alone for 30 years. He it was who first showed that indi vidual nerve cells are recognizable and functionally important and have 'per sonalities' of their own.

Taschenbuch. Condition: Neu. Neuware - Transposon tagging can work. Even though most of our understand ing about the factors that contribute to a successful tagging experiment has been accumulated from a limited number of experiments using different transposable elements in different genetic backgrounds, it is still possible to draw some conclusions regarding the best experimental strategies for gene tagging. In our experience, Spm has proved to be a good element for transposon tagging. The frequency of recovering mutable alleles in duced by Spm is not significantly different from that for Ac-Ds or for Mu 6 (summarized in Ref. 22) and varies from about 10- to 10=zr:-8pm has the unique advantage, however, in that all of the members of thiSfumily that have been examined thus far are homologous to each other at the DNA level. Therefore, by combining molecular analysis with genetic segre gation, it is possible to identify and isolate alleles that are due to insertions of either autonomous or nonautonomous Spm elements. There are definite steps one can take to increase the chances of de tecting a transposition into the gene of interest. The most important step is to select a genetic background in which the desired phenotype will be easy to screen. If the phenotype is not likely to be mutable, then tester lines should be constructed so as to contain flanking markers that can aid in subsequent segregation analyses.

It was hosted by Professor Giuseppe Maschio, Professor of Medicine and Chief, Department of Nephrology at the University of Verona. The Sixth Workshop maintained the tradition of the previous ones. It provided a unique and outstanding opportunity for close interaction between scientist involved in the research of the overall field of Mineral Metabolism. The current Workshop was attended by 250 scientists from 15 countries including Austria, Canada, Denmark, England, France, Germany,Holland, Israel, Italy, Japan, Spain, Sweden,Switzerland, and the United States of America. The topics discussed included the renal handling of phosphate, transport of other minerals, intestinal absorption of calcium and phosphate and phosphate homeostasis in health and disease. Two symposia dealing with the recent developments of the interactions between minerals, parathyroid hormone, and blood pressure and between minerals and myopathies were included. In addition to the 15 State-of-the-Art Lectures, there were 43 oral and 63 poster presentations selected from over 200 abstracts sub mitted to the Program Committee. The Seventh International Workshop on Phosphate and Other Minerals will be held during September, 1985, in Marseille, France. It will be hosted by Professor Michel almer, Chief of the Department of Nephrology at the University of Marseille. The theme of this coming Workshop will focus on the pathophysiology of phosphate homeostasis and the metabolism of other minerals.

Since the first symposium in 1960, each successive meeting has broken new ground in the field of pharmacological control of lipid levels - offering new and stimulating insights and exposing the audience to the state of the art. The field has progressed sufficiently to permit discussion of the cellular biology of athero sclerosis. The opening session was devoted to pathology, macrophages, lipoproteins and their receptors and choles terol ester metabolism. Because of the recent emergence of new apolipoprotein technology, a workshop devoted sole ly to apolipoprotein methodology was introduced followed by a plenary session devoted to their metabolism and structure. Another rapidly developing area of atherosclerosis research is non-invasive assessment of this condition. Accordingly, a session was devoted to new techniques for this research modality. The final plenary sessions were devoted to the roles of drugs and diet in athero~ scl~rosis - cause, treatment and mechanisms of action. The meeting was summarized by Dr. O.J. Pollak, one of the 'founding fathers' of this field. There were nine sessions of proffered papers whose abstracts appear in this volume. In addition, special workshops (to be reported elsewhere) were devoted to several drugs including Oiyzanol, Probucol and Etofibrate.

Taschenbuch. Condition: Neu. Neuware - Research on the study of membrane toxicity has advanced a great deal in a relatively short period of time, prompting scientists to re-examine the problems associated with carriers, receptors and reactors to toxic substances. This book presents current research on the responses of membranes to toxic sub stances both by direct observation of macromolecules reacting with these substances and by inference from data on the bio chemical responses of cells and cell fractions. Two basic areas of membrane toxicity are analyzed by a large number and variety of scientists in this field. The first area is the effect of various toxic substances on membrane structure and function. The second area is where the membrane serves as the site of rate limiting step of the transport of various toxic substances. The aim of the book is to evaluate present concepts of membrane structure and function in relation to exposure to envir onmental toxicants. The book is divided into five sessions: 1. Xenobiotics and Membrane Transport 2. Cellular Responses to Toxins 3. Effects of Membranes and Receptors 4. Modification of Membrane Function by Toxicological Agents 5. Toxic Chemicals as Molecular Probes of Membrane Structure and Function Each paper is generally concluded by an edited discussion which contains many useful and interesting additional insights in each subject area. v ACKNOWLEDGEMENT We gratefully acknowledge the support provided for this conference by the U. S. Energy Research and Development Administration, the Environmental Protection Agency and the University of Rochester.

Taschenbuch. Condition: Neu. Neuware - Since 1966, at ro~ghly three-yearly intervals, an internation al group of immunologists has met somewhere in Europe to discuss the latest developments in our understanding of the mechanisms governing the functioning of the immune system in vivo. These meetings have become known as the International C,mferences on Lymphatic Tissues and Germinal Centers in Immune Reactions, or for the regular devotees, simply as the Germinal Cent'~r Conferences (GCC). This volume represents the proceedings of the 8th GCC, which was held in Babraham, near Cambridge, UK, between the 14th and 17th August, 1984. When one considers how cellular immunology has become increas ingly dominated by in vitro methodology over the past twenty years, it may seem remarkable that these conferences hav~ survived at all, let alone prospered. However, I for one do not find this surprising, since I suspect that the exquisitely :omplex architect ure and microenvironments of the lymphoid system will never be fully understood through in vitro studies. If 'tae proper study of mankind is ~an', then surely ultimately the proper study of all the interacting elements which comprise the immune system has to be in vivo. This belief is shared by a substantial number of immunol ogists, as the contents of this volume will attest. Although the GCC were originally devoted to unravelling the mysteries of the germinal center response (and these are still not fully resolved), over the years the scope of the meetings has inevitably broadened.

Taschenbuch. Condition: Neu. Neuware - This volume contains most of the papers presented at the First International Symposium on The Effect of Prolonged Drug Usage on Fetal Development held at the Beit-Berl Convention Center, Kfar Saba, Israel, on September 14 - 17, 1971. In order to obtain an overview of the effect of drugs on fetal development, it appeared desirable to gather the opinions of noted investigators regarding the goals already achieved and the future potential of prevention of fetal disorders due to drugs. More than one hundred and sixty scientists from fifteen countries participated, and over forty presented data which were collected in extensive laboratory, clinical and field studies. This small, comparatively informal, International Symposium was held in a relaxed environment and provided a suitable forum for scientists in many differing lines of research to evaluate together the recent advances in the role of drugs as teratogenic agents and methods for the rapid uncovering of the teratogenic potential of drugs to mankind.
