Taschenbuch. Condizione: Neu. Neuware -by Ronald G. Corwin What do the following have in common: regulatory agencies, magnet schools, a declining empire, puritan asceticism, plea bargaining, the recent tax revolt in California, the Boston Tea Party, the Vietnam War, public drinking halls during Prohibi tion, police entrapment, a…nd Yosemite National Park on Labor Day weekend If the answer is not readily apparent, read this engaging book. Dr. Sam Sieber makes a convincing case that harbored in a potpourri of such events are countless instances of how well-intentioned social interventions often produce harmful effects. Searching for a general framework that will force us to think of heretofore discrete events in new ways, he has chosen to use the term 'intervention' in its broadest sense. His approach is a superb example of how serious schol arship can produce a new creative synthesis from familiar knowledge when the scholar is guided by a lively curiosity. The wide-ranging subject matter of this book provides a re freshing vision of social reform movements and programs. I think that Sieber has succeeded in doing what he set out to do: namely, to develop a general and inclusive typology for cl- ix x RONALD G. CORWIN sifying and interpreting the perverse effects of all kinds of social interventions. This is not merely another treatise on the 'unintended effects' of purposeful action, however. As Dr.

Taschenbuch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -1. THE SEMIOTIC CHARACTER OF ABORIGINAL SIGN LANGUAGES In our culture, language, especially in its spoken manifestation, is the much vaunted hallmark of humanity, the diagnostic trait of man that has made possible the creation of a… civilization unknown to any other terrestrial organism. Through our inheritance of a /aculte du langage, culture is in a sense bred inta man. And yet, language is viewed as a force wh ich can destroy us through its potential for objectification and classification. According to popular mythology, the naming of the animals of Eden, while giving Adam and Eve a certain power over nature, also destroyed the prelinguistic harmony between them and the rest of the natural world and contributed to their eventual expulsion from paradise. Later, the post-Babel development of diverse language families isolated man from man as weIl as from nature (Steiner 1975). Language, in other words, as the central force animating human culture, is both our salvation and damnation. Our constant war with words (Shands 1971) is waged on both internal and external battlegrounds. This culturally determined ambivalence toward language is particularly appar ent when we encounter humans or hominoid animals who, for one reason or another, must rely upon gestural forms of communication. 476 pp. Englisch.

Taschenbuch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -By way of introduction to this fascinating book, let me highlight two of its many contributions. First, it is a good example of something all too rare in sociology: testing competing general theories. Most of us either try to devel…op or refine theories about how the social world works, and cite convenient data as support, or we select and collect data that will fit some general theoretical position. In the first case, the data playa subor dinate role-bits of evidence for our view of life. In the second, the theory plays a subordinate role-a way to make sense of the social behavior we have observed. McCaffrey's position subsumes these two. He has gathered data on an important social agency, but with an im plicit problem in mind: which of the several theories about the social world he was exposed to in graduate school would do the best job of interpreting the data Or, we might just as well turn it around. In a graduate department such as Sociology at the State University of New York at Stony Brook, there is a lively, never ending debate about the 'truth' of competing perspectives on the political and social world. By selecting a data base and remaining alert to the kind of evidence each theory required, McCaffrey circumvented the usual' data for a theory' vs. 'a theory for the data' dilemma that most of us live with. 212 pp. Englisch.

Taschenbuch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -Mankind is living through a crucial period of its history. An arms race without precedent in intensity and duration, which developed in the postwar period, has left on our planet enor mous stockpiles of weaponry, which, should they… be used in war, could cause irreparable damage to world civilization and even threaten the human race with extinction. Hence the most vital and urgent task in the world today is to end the arms race-as well as the mutual mistrust, tension, and hostility that it gener ates in relations between states. The Soviet Union and other countries of the socialist com munity have for many years concentrated their foreign policy efforts on clearing the dark and putrid atmosphere of the Cold War which poisoned relations between states with different social systems. Guided by the great Lenin's teachings, we have worked consistently for simple, reasonable, and realistic princi ples of peaceful coexistence, mutual respect for sovereign rights, and mutually beneficial cooperation to prevail in these relations. We have sought to counter the policy of alienation and hos tility among nations, resulting in the world balancing on the brink of war, by encouraging a transition to normal, courteous relations, to peaceful cooperation based on equality-in short, to what is now termed detente. Such is, in effect, the primary aim of the foreign policy guidelines established by the last two congresses of the Com munist Party of the Soviet Union-the 24th and 25th-known as the Soviet Peace Program. 216 pp. Englisch.

Taschenbuch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -From July 31 to August 13 a NATO Advanced Study Institute on Photosynthesis was held at the Anargyrios and Korgialenios School on the Island of Spetsai. Greece. The Institute focused on techniques and recent advances in photosynthe…sis research and brought together teachers and students with a wide range of interest and experience. It was a very stimulating occasion which allowed cross-fertilization to occur between biophysicists. biochemists, molecular biologists and physiologists. Lectures and discussions ran~ed from the description of the molecular structure of the photosynthetIc bacterial reaction centre and of tobacco Rubisco through to the regulation of carbon metabolism and the application of genetic engeering. This book is comprised of the contents of the major lectures and a selection of relevant posters displayed at the Institute. Taken together the book is an excellent representation of the most up to date thoughts and activities in photosynthesis research across a wide, but interlocking. spectrum of topics. The papers presented here are a written record of the high quality of both the lecturers and students alike and emphasises the value of the NATO ASI series as a reference source. The successful organisation of the Institute and the production of this book would not have been possible without the support of our colleagues. We therefore wish to thank Pam Cook, Lyn Barber. Niki Gounaris, Alison Telfer. Sotiria Nikolaidon, David Chapman, Steven Mayes and Wei Qiu Wang for all their help during the course of the Institute. 628 pp. Englisch.

Taschenbuch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -The first and foremost concrete fact which every one will affirm to belong to his inner experience is the fact that consciousness of some sort goes on. I -William James, 1893 We are witnessing today a mounting interest among behavi…oral and biological scientists in problems long recognized as central to our understanding of human nature, yet until recently considered out of the bounds of scientific psychology and physiology. Sometimes thrown into the heading of 'altered states of consciousness,' this growing research bears directly upon such time-honored questions as the nature of conscious experience, the mind-body relationship, and volition. If one broadly views this research as encompassing the two interrelated areas of consciousness and self-regulation, one can find many relevant contemporary examples of creative and experimentally sophisticated approaches, including research on the regulation of perception and sensory experience, attention, imagery and thinking, emotion and pain; hypnosis and meditation; biofeedback and volun tary control; hemispheric asymmetry and specialization of brain func tion; drug-induced subjective states; and biological rhythms. Because the material is spread over many different kinds of publications and disciplines, it is difficult for anyone person to keep fully abreast of the significant advances. The overall aim of the new Plenum Series in Consciousness and Self-Regulation: Advances in Research is to provide a scholarly forum for discussing integration of these diverse areas by presenting some of the best current research and theory. 472 pp. Englisch.

This item is printed on demand - it takes 3-4 days longer - Neuware -2 ence of a wave zone or induction zone under industrial and exper imental conditions determines the physical values used to assess the intensity of irradiation (the power flux density or the field in tensity), the instruments used… for measuring, and the experimental technique (irradiation from a distant source, in a cavity resonator, inductor, capacitor, and so on). The physical parameters eVidently also determine the biolog ical effects of the different frequency bands. In recent decades various bands of radio waves have been extensively used in many branches of industry. The microwave band has been widely applied in the field of radar, radionavigation, radioastronomy, radiometeorology, radiocommunication, nuclear physics, and physiotherapy. The short-wave and ultrashort-wave band are used for physiotherapy, radiocommunication, broadcast ing, television, and also for the heat treatment of dielectrics and for welding plasticized rubber. The long and medium waves are used for the heat treatment of metals in the vacuum-tube industry and in mechanical engineering. 156 pp. Englisch.

Taschenbuch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -Scope of the book, and acknowledgements.- The articles are focused on 'real problems' in body-fluid analysis, typically with a final chromatographic separation of ~g or often ng amounts if the aim is quantitation. The pitfalls may…not be realized by a typical chemist (cf. remarks in #A-3), but he may excel in metabolite iden tification - which this book covers to a fair extent. Where identity is known, and the metabolite could interfere in therapeutic drug monitoring or in diagnosis or itself have clinical relevance, useful guidance will come from articles that follow. Authors have gone to much trouble, and are not to be blamed by any reader who would have liked an introduction to chromatography or to metabolic pathways (cf. list of conjugation reactions at end of concluding article). Appre ciation is also expressed for permission to reproduce published mat erial; the acknowledged sources include 1. Chroma tog. (Elsevier; e. g. in #A-l) , Anal. Chem. (American Chemical Society; #A-2) and Wiley. 304 pp. Englisch.

Taschenbuch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -Intended as an introduction to robot mechanics for students of mechanical, industrial, electrical, and bio-mechanical engineering, this graduate text presents a wide range of approaches and topics. It avoids formalism and proofs bu…t nonetheless discusses advanced concepts and contemporary applications. It will thus also be of interest to practicing engineers. The book begins with kinematics, emphasizing an approach based on rigid-body displacements instead of coordinate transformations; it then turns to inverse kinematic analysis, presenting the widely used Pieper-Roth and zero-reference-position methods. This is followed by a discussion of workplace characterization and determination. One focus of the discussion is the motion made possible by sperical and other novel wrist designs. The text concludes with a brief discussion of dynamics and control. An extensive bibliography provides access to the current literature. 60 pp. Englisch.

Taschenbuch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -Until recently the only biomedical use of erythrocytes was in transfusion medicine to restore a normal oxygen delivery. The development of a technology that permits one to open and reseal erythrocytes has dramatically changed this…perspective. Currently, a number of teams have shown that engineered erythrocytes can behave as circulating bioreactors for the degradation of toxic metabolites or the inactivation of xenobiotics, as drug delivery systems, as carriers of antigens of vaccinal interest, and in many others biomedical applications. The technology of opening and resealing the erythrocytes has also been used successfully to investigate several basic aspects of erythrocyte metabolism, survival, pathology, etc. Thus, researchers in this field have an extraordinary opportunity to specifically modify the erythrocytes by the introduction of enzymes that generate new metabolic abilities, antibodies that inactivate single metabolic steps, or metabolites that can influence oxygen delivery and/or other cell properties. Furthermore, the pharmacokinetics of any drug can be potentially manipulated by using the erythrocytes as a delivery system. This book, The Use of Resealed Erythrocytes, is based on the fourth meeting of the 'International Society for the Use of Resealed Erythrocytes as Carriers and Bioreactors' (I. S. U. R. E. ), held in Urbino, Italy, in 1991, and examines the most recent applications and developments of this technology. 380 pp. Englisch.

Taschenbuch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -About four or five years ago one began to hear about the enormous interest being taken in on-line consoles and displays. Nothing much was done with them, but computer men felt that this was the way computing ought to go: one might…dispense with cards, and overcome many of the problems of man-machine communication. It quickly appeared that, as with computers, there had been a great under estimation of the amount of work involved, of the difficulties of programming, and of the cost. So it began to emerge that graphics was not the ultimate answer, in spite of superb demonstrations where one might watch a square being converted into a cube and then rotated. But my mind goes back to 1951 and the first computers. There, there were demonstrations of arithmetic speed and storage facility; but not much idea of actual use. However, we now understand how to use computers, and in the last year or two, significant developments in the field of graphics have led to genuine applications, and economic benefits. The equipment is still expensive, but it is becoming cheaper, more uses are being found, and f believe that we are just at the stage when the subject is gaining momentum, to become, like computers, a field of immense importance. 256 pp. Englisch.

Taschenbuch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -Waves critically affect man in coastal regions, including the open coasts and adjacent continental shelves. Preventing beach erosion, designing and building structures, designing and operating ships, providing marine forecasts, and… coastal planning are but a few examples of projects for which extensive information about wave conditions is critical. Scientific studies, especially those in volving coastal processes and the development of better wave prediction models, also require wave condition information. How ever, wave conditions along and off the coasts of the United States have not been adequately determined. The main categories of available wave data are visual estimates of wave conditions made from ships at sea, scientific measurements of waves made for short time periods at specific locations, and a small number of long-term measurements made from piers or offshore platforms. With these considerations in mind, the National Ocean Survey of the National Oceanic and Atmospheric Administration sponsored the Ocean Wave Climate Symposium at Herndon, Virginia, July 12-14, 1977. This volume contains papers presented at this symposium. A goal of the symposium was to establish the foundations for a com prehensive and far-sighted wave measurement and analysis program to fully describe the coastal wave climate of the United States. Emphasis was placed on ocean engineering and scientific uses of wave data, existing wave monitoring programs, and modern measure ment techniques which may provide currently needed data. 384 pp. Englisch.

Taschenbuch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -Research related to the pineal gland has advanced rapidly in the last three decades since the discovery of its most important hormone, melatonin. This indoleamine has been shown to have a large variety of effects in the organism; t…he bulk of these actions were initially thought to relate the pineal gland to the reproductive and endocrine systems. It is now apparent, however, that the physiologic interactions of the pineal and its hormones far transcend its control of endocrine function. One field of pineal research that has developed rapidly within the last 5 years has been the demonstration of its relationship to the immune system. Since the pineal gland is part of the central nervous system, these observations generally fall in the category of neuroimmunology, an area that, in its own right, has received a great deal of attention in the last decade. Thus, a NATO Advanced Study Course entitled 'Role of Melatonin and Pineal Pep tides in Neuroimmunomodulation' was convened in Erice, Sicily, on June 3-9, 1990. This book is a result of the scientific presentations given at the workshop. The contributions to the book include mini-review articles which summarized the presentations of the invited speakers as well as a selected number of brief communications where the subject matter was in line with the theme of the Advanced Study Course. 344 pp. Englisch.

Taschenbuch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -Targeting of drugs via carrier systems to sites in the body in need of pharmacologic intervention is a rapidly growing area of research in the treatment or prevention of disease. It has evolved from the need to preferentially deliv…er drugs, enzymes, vitamins, hormones, antigens, etc. to target cells and organs so as to avoid toxicity, waste of drugs through premature secretion or inactivation and at the same time render treatment more convenient and cost-effective. A wide assortment of naturally occ urring or semi-synthetic drug carriers (e. g. antibodies, glycoproteins, lectins, peptide hormones, cells and liposomes), their inter action with relevant receptors and mediation of optimal pharmacological action were discussed in the two previous NATO Advanced Studies Institutes (ASI) of this series, 'Targeting of Drugs' and 'Receptor-Mediated Targeting of Drugs', the proceedings of wh ich were published by Plenum in 1982 and 1984 respectively. This book contains the proceedings of the 3rd NATO ASI 'Targeting of Drugs with Synthetic Systems' held as be fore at Cape Sounion, Greece during 24 June-5 July 1985. It deals mostly with man-made carriers such as a variety of polymers, matrices, liposomes and other colloidal micro particles. The twenty chapters discuss the interaction of such carriers with the biological milieu, approaches to bypass the reticuloendothelial system (or, when needed, take advantage of its interception of carriers to optimally deliver drugs to phagocytes) and ways to improve delivery to specific cells, often with the help of carrier-linked ligands. 308 pp. Englisch.

Taschenbuch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -Over the past decade, the AIDS pandemic has propagated so widely and exerted such a dev astating impact that one may properly ask the question, Why not concentrate all AIDS efforts on disease control alone Why link AIDS with women'…s reproductive health What is the scientific basis for this linkage And how might AID~ control and women's health objectives be promot ed simultaneously These questions constitute the principal themes addressed in this monograph. The 15 chapters in this volume are intended to provide state-of-the-art reviews of key interac tions between AIDS and women's reproductive health for an audience of scientists and policy makers in the AIDS and population fields. Impetus for this monograph comes in pan from what we perceive to be an inadequate global response, thus far, to AIDS and women's health ;roblems. A common platform has failed to emerge among the disparate professional communities working in the areas of AIDS, STDs, and family planning. As a result, endeavors in these fields have been isolated, and opportunities for joint action have been missed. An enormous and, as yet, unharnessed potential exists for power ful interdisciplinary collaborations that could strengthen policies and programs against these pressing health problems of humankind. 220 pp. Englisch.

This item is printed on demand - it takes 3-4 days longer - Neuware -Water covers about two-thirds of the surface of earth, but only 0.627 percent of this water is the sweet surface and subsurface water available for the survival of freshwater organisms including man (1,2). Some of this fresh or swe…et water lies in practically uninhabitable regions (rivers: }1ackenzie in Canada; Amazon in Central America; Ob, Yenesey, and Lenta in Siberia, etc.). Also, most of the major rivers (the Mississippi in U.S.A., the Rhine in Europe, the Volga in U.S.S.R., the Ganges in India, etc.), because they flow through agricultural land or urban and industrial areas, have become highly contaminated with chemicals (3). This leaves us with shrinking resources of sweet surface water. In the United States, the dependable supplies of this water are already dwindling in cities like New York and Los Angeles and states like New Mexico and Texas (3). 276 pp. Englisch.

The Meeting (Advanced Research Workshop-Lect…ure Course) was co-sponsored by NATO, FEBS and IUB, and was held under the auspices of the International society for Chloro plast Development, the Greek Ministry of Industry, Research and Technol ogy, and the National Center for Scientific Research 'Demokritos'. The Meeting focused on recent advances in the field of chloroplast biogenesis and the regulatory mechanisms underlined, and brought together over 120 experts and students of the field from 22 countries. The subject of chloroplast biogenesis has experienced great progress in recent years mainly thanks to the application of Molecular Biology techniques and methodology. New findings that emerge gradually unravel the regulatory mechanisms involved in the assembly, stabilization and growth of the photosynthetic units in thylakoids, the signal transduction chain leading from photoreception to gene expression, the transport of nuclear-coded proteins into stroma-soluble supramolecular enzyme complexes as well as thylakoid-bound supramolecular complexes, involved in light-energy transduction. It was the aim of this meeting to bring together experts and students coming from diverse disciplines (ranging from Botany and plant physiology to Molecular Biology, Biophysics and Biotechnology), to discuss the recent advances in the field so that thorough exchange of ideas and working hypotheses would be achieved. 656 pp. Englisch.

Taschenbuch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -A NATO Advanced Study Institute held in Portugal in 1968 on cellular biology directed our attention to the important role that biological membranes played in the fundamental life processes, e.g. the transportation of cellular nutri…ents into cells and into subcellular par ticles coupled with energy use/or generation. A consi deration of biomembranes and their structure led us to organize a self-supporting course in 1972 under the gen eral sponsorship of the American Oil Chemists' Society on 'Fundamentals of Lipid Chemistry.' This course con cluded with important papers on lipoproteins, membrane structure and membrane models. The papers presented at the short course were published under the same title. With the background of the lipid course, a third program was developed entitled 'Biomembranes - Lipids, Proteins and Receptors' and held as a NATO Advanced Study Insti tute in 1974. This ASI explored the structure of bio membranes and the relationship of non-lipid components to membrane function. This ASI was also published to provide the conference proceedings to interested scien tists who could not attend. 428 pp. Englisch.

Taschenbuch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -Several model systems have been used to understand the cellular and molecular mechanisms of differentiation of mammalian nerve cells. Each model system has unique advantages and disadvantages and is suited for the study of only cer…tain aspects of differentiation. In this book, the techniques of these models and the usefulness and limita tion of each model system are discussed. An awareness of the use and misuse of each model system is important for a rational interpretation of data and for a reasonable comparison of data obtained from different model systems. With the use of clonal lines of neuronal cells and hybrid neural cells (neural cells x nonneural cells), many new concepts have emerged con cerning the regulation of differentiated functions, the relationship between the expressions of individual differentiated functions, and the relationship between differentiation and malignancy. Some of these concepts have already proved to be relevant to regulation of differentiation in vivo. These new emerging concepts are discussed extensively in this book. Many new agents (physiological and nonphysiological) which induce or increase the expression of one or more differentiated functions have been identified. These agents will be useful biological tools for further studies of the regulation of differentiation in mamma lian nerve cells. This book describes the role of each agent in d- vii viii PREFACE ferentiation of nerve cells by focusing on different model systems and provides a rational basis for selecting the particular differentiating agents for specific problems of differentiation processes. 260 pp. Englisch.

This item is printed on demand - it takes 3-4 days longer - Neuware -That residues of pesticide and other contaminants in the total environ ment are of concern to everyone everywhere is attested by the reception ac corded previous volumes of 'Residue Reviews' and by the gratifYing en. thusiasm, sinc…erity, and efforts shown by all tve individuals from whom manuscripts have been solicited. Despite much propaganda to the contrary, there can never be any serious questions that pest-control chemicals and food-additive chemicals are essential to adequate food production, manufac ture, marketing, and storage, yet without continuing surveillance and intel ligent control some of those that persist in our foodstuffs could at times con ceivably endanger the public health, Ensuring safety-in-use of these many chemicals is a dynamic challenge, for established ones are continually being displaced by newly developed ones more acceptable to food technologists, pharmacologists, toxicologists, and changing pest-control requirements in progressive food-producing economies. These matters are of genuine concern to increasing numbers of gov ernmental agencies and legislative bodies around the world, for some of these chemicals have resulted in a few mishaps from improper use. Adequate safety-in-use evaluations of any of these chemicals persisting into our foodstuffs are not simple matters, and they incorporate the considered judgments of many individuals highly trained in a variety of complex biologi cal, chemical, food technological, medical, pharmacological, and toxicologi cal disciplines. 156 pp. Englisch.

Taschenbuch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -The changing role of industry, the trend towards automation, the in creased cost of raw materials and labour rates all emphasize the need for improved quality of manufacture which will lead to better reliability, reduced maintenanc…e costs and incidence of failure, as well as greater consumer confidence. Many countries, including Japan, are noted for their high quality of manufacture. This has helped them monopolize the world radio and television market and achieve great in-roads into the motor industry. If other economies are to compete effectively against such competition, then improvements in quality and performance of products are necessary. The need for control of quality embraces many fields from design, manufacture, function testing and inspection, through to an understand ing of sampling procedures and sampling theory, embracing both employee and management responsibilities to the maintenance of quality. The aim of this book is to give an understanding of industrial quality control. The techniques described have been selected so that they may be applied to industrial problems. It is hoped and expected that these methods will lead to improvements in quality and economics of manufac ture, thus leading to increased productivity and profitability. 9 1 The Need for Quality Control The major goals for quality control are manifold and include a need to determine the real functional tolerances required for engineering specifications and to provide a plan for control of the quality of the results of a process related to time. This is normally achieved by statistical or control chart methods. 264 pp. Englisch.
