Taschenbuch. Condición: Neu. Neuware - Volume 1 of Theory and Research in Belwvioral Pediatrics drew attention to issues related to the assessment of the preterm infant, to organizational processes in infant development, and to the systemic nature of caregiver-infant relationships. Vol ume 2 continued the theme of systemic organization while ex amining various contextual and ecological factors that affect development during infancy and childhood. Volume 3 con tinues these themes. Interdisciplinary and cross-disciplinary studies, cross-cul tural comparisons, prospective longitudinal designs, and so phisticated multivariate correlational models have encouraged developmentalists to formulate new conceptualizations of the dynamic relationships among those organismic, transactional, and ecological variables that regulate organizational processes. As a result, many traditional models of development have been discarded or, at minimum, have been markedly transformed. Similarly, many time-honored 'facts' of development have been seriously challenged both theoretically and empirically. In Chapter 1, Philip R. Zelazo challenges traditional ap proaches to infant developmental assessment. Zelazo goes a step beyond noting the poor predictive validity of infant devel opmental examinations, by arguing that such examinations bias the evaluation of infants with handicapping conditions. The emphasis in standard developmental examinations on motor performance, receptive language, and behavioral compliance Vll Vlll PREFACE works against infants whose handicapping conditions involve neuromotor, attentional, or auditory dysfunctions. Zelazo's pro posed alternative is to directly assess mental activity using cog nitive-behavioral measures of mental competence derived from central processing models of schema formation.…

Taschenbuch. Condición: Neu. Neuware - The chapters of this volume were originally presented at a symposium on 'Depression in Schizophrenics' held at the University of Calgary, Health Sciences Centre on July 06 and 07, 1988. It was the intent of the organizers to draw together leading international researchers to address, in a comprehensive fashion, the persisting problem of depression in schizophrenic individuals. As many of the authors point out, depression was clearly identified as a central problem in schizophrenia by the pioneers of psychiatry. Their wisdom and clinical acumen was lost for a time to be only recently re discovered. Their insights must now be integrated with modern taxonomic systems, evolving etiological models and methods of assessment. With increased recognition of the problem of depression in this population we must also examine appropriate methods of ameliorating the suffering of those afflicted. The conference was divided into sections (theoretical aspects, phenomenology, suicide and treatment) and the chairmen of these sections have given brief introductions. Necessary overlap of topics and methods provided a convergent and validating examination of empirical results which may serve to direct continuing studies. As well we hope that thoughtful review may directly influence clinical practice and thereby improve the quality of life for schizophrenic patients.…

Taschenbuch. Condición: Neu. Neuware - The psychiatric view of homosexuality has undergone a fascinating evo lution in recent years. This includes not only the change from viewing homosexuality as a diagnosable illness, as opposed to an alternative life style, but also the development of considerable professional concern for providing appropriate mental health services to this previously under served minority community. There has been an increasing recognition of the need for comprehensive services including, but not limited to, counseling, individual psychotherapy, and couples therapy. This book is written for the practicing clinician, and offers a compre hensive survey of the important clinical issues involved in the counsel ing and psychotherapy of gay men and lesbian women. It is an extraor dinarily practical book and its breadth and depth make it appropriate for both the novice and the experienced therapist. SHERWYN M. WOODS Series Editor ix Preface We hear our mentors but do not often heed them. Freud's supportive, nonjudgmental approach to homosexuality provided an ambience with in which discoveries could be made, that is, the discovery that homosex uality was not a disease of mental degeneration and that sexuality, in the sense of a fundamental human propensity to find pleasure in social and physical attachments, was at its root directed to both sexes. The ad herence to a nonjudgmental approach was short-lived, suffered repres sion by homophobic defenses, and scientific zeal was directed toward 'cure' rather than comprehension of the homosexual state.…

Taschenbuch. Condición: Neu. Neuware - Families are undergoing dramatic changes in our society. Our tradi tional views are being challenged by new family arrangements. These new family arrangements are forcing redefinitions of what consti tutes a family and raising significant issues regarding the potential developmental consequences for children in these families, if such exist. Moreover, the ramifications of redefined families and their bear ing on children's development extend into the legal, political, and societal arenas. This book focuses on the relationships between di verse family arrangements and children's development, as well as on legal and social implications. Our interest in this area emanates from our experience in directing the Fullerton Longitudinal Study. In the course of this investigation, we observed families undergoing transformation, most commonly in maternal employment and marital status. Our initial research on the role of maternal employment in children's development provided the scientific foundation for our interest. Just as we feel that maternal employment and dual-earner families should be comprehensively re searched regarding their relationships to children's development, we also believe that other contemporary family arrangements should receive extensive attention in the developmental literature. Hence, the idea for this book emerged.…

Taschenbuch. Condición: Neu. Neuware - Just over 20 years ago the publication of two books indicated the reemergence of Darwinian ideas on the public stage. E. O. Wilson's Sociobiology: The New Synthesis and Richard Dawkins' The Selfish Gene, spelt out and developed the implications of ideas that had been quietly revolutionizing biology for some time. Most controversial of all, needless to say, was the suggestion that such ideas had implications for human behavior in general and social behavior in particular. Nowhere was the outcry greater than in the field of anthropology, for anthropologists saw themselves as the witnesses and defenders of human di versity and plasticity in the face of what they regarded as a biological determin ism supporting a right-wing racist and sexist political agenda. Indeed, how could a discipline inheriting the social and cultural determinisms of Boas, Whorf, and Durkheim do anything else Life for those who ventured to chal lenge this orthodoxy was not always easy. In the mid-l990s such views are still widely held and these two strands of anthropology have tended to go their own way, happily not talking to one another. Nevertheless, in the intervening years Darwinian ideas have gradually begun to encroach on the cultural landscape in variety of ways, and topics that had not been linked together since the mid-19th century have once again come to be seen as connected. Modern genetics turns out to be of great sig nificance in understanding the history of humanity.…

Taschenbuch. Condición: Neu. Neuware - In the myth of Daphne and Apollo, Cupid fired two arrows: one causing flight from love, the other passionate attraction. Cupid aimed his first arrow at Daphne, a beautiful nymph who loved her freedom; the next struck Apollo, who lusted after Daphne. Daphne, frightened and intent upon virginity, fled Apollo but was unable to run fast enough. When her strength was almost gone, she sought protection in the familiar waters of her father's river. He answered her prayers: Her hair became leaves, and her feet, roots growing into the ground; she was transformed into a laurel tree. Apollo, kissing the sprouting bark, pledged to honor Daphne by placing a laurel wreath on the head of every hero who won a victory. Unable to evade the consequences of the arrow that wounded her, Daphne called upon the river, the creative power of both nature and time-a symbol of fertility, but also of oblivion-to help her survive when her strength was gone. Daphne's inner triumph in the face of injury is an appropriate sym bol for the types of transformation witnessed by psychologists. In his book on symbols, Circlot (1962, p. 173) writes that the crowning of the poet, artist, or conqueror with laurel leaves 'presupposes a series of inner victories over the negative and dissipative influence of the basest forces. ' Further, the tree 'denotes the life of the cosmos: its consistence, growth, proliferation, generative, and regenerative processes' (Circlot, 1962, p. 328). …

Taschenbuch. Condición: Neu. Neuware - Neuropsychology has its roots in clinical neurology. Reading case de scriptions by 19th century neurologists, such as Wernicke's painstakingly detailed examinations of patients with the 'aphasic symptom-complex,' makes it obvious that neuropsychology is not a new discipline. Even the marriage with psychology is not new; the neurologist Arnold Pick, for example, was fully conversant with the developments in contemporary psychological as well as linguistic research. However, the primary focus of 19th and early 20th century psychology was on 'general psychology,' and only a small number of psychologists ventured into what then was called 'differential psychology' (the psychology of individual dif ferences) including a few who became attached to neurological research and rehabilitation units after World War I. It remained until World War II for psychologists to establish a more solid working relationship with neurology. What psychology had to offer to neurology was its experimental skill, the development of a sophisticated methodology, and, for clinical work, the development of psychometrics. On the whole, the marriage between the two disciplines has been fruitful, leading to new insights, models, and discoveries about brain-behavior relationships, documented in several textbooks which appeared in rapid succession since the 1960s. In clinical practice, neuropsychology has been inventive in some respects, in others merely introducing psychometric rigor to already existing neurological examinations. As described in greater detail in this book, developmental neuropsy chology is of even more recent origin.…

Taschenbuch. Condición: Neu. Neuware - Since the first edition of this volume was published in 1976, interest in the problem of intelligence in general and infant intelligence in particu lar has continued to grow. The response to the first edition was hearten ing: many readers found it a source of information for the diverse areas of study in infant intelligence. Because of the success of that volume, we have decided to issue a second edition. This edition is in many ways both similar to and different from the first. Its similarity lies in the fact that many of the themes and many of the contributors remain the same. Its difference can be found in the updating of old chapters and the addition of several new ones. Taken together, the chapters present a rounded picture of the cen tral issues in infant intelligence. Because the aim was to present a picture of the issues, no attempt, other than the selection of authors and themes, can be made to integrate these chapters into a single coherent whole. In large part, this reflects the diversity of study found in the area of early intellectual behavior. Rather than having a comprehensive theo ry of infant intelligence, the field abounds with a series of critical ques tions. To unite these chapters into some coherence, it will be necessary to articulate what these issues might be. Five major themes run through out the field of infant intelligence and thus through this volume.…

Taschenbuch. Condición: Neu. Neuware - If ever a book could be called timely, this is it. Sleep disorders medicine has made rapid advances in recent years. The field has attained growing respectability, with a textbook recently published, a congressionally man dated National Commission on Sleep Disorders Research, and a growing public awareness of the importance of sleep disorders. However, this rapid growth has made the discrepancy among certain components of the field all the more obvious. Thus, we find that patients who complain of insom nia are almost never in the majority of those seen in sleep disorders centers, in spite of the well-known fact that the prevalence of such individ uals in our society is by far the largest. Current articles on insomnia abound, but they tend to be facile recitations of diagnosis and impractical global recommendations for treat ment, without providing the essential details. Indeed, the clinical profes sions really do not know what to do about insomnia. This is reflected in a number of observations I have made in the recent past. For example, the majority of individuals who complain of insomnia take alcohol, aspirin, over-the-counter medications, hot baths, and a host of other nostrums, but rarely seek a physician. In the unlikely event that a physician is consulted, he is likely to prescribe a sleep medication but without any particular consistency, or any clear instructions on its use.…

Taschenbuch. Condición: Neu. Neuware - The NATO-Advanced Research Workshop 'Esterases, Lipases and Phospholipases: From Structure to Clinical Significance' was held at the University of Bordeaux II, France from 22nd- 24th September 1993 under the Directorship of Professor Michel Clerc of the University of Bordeaux II. The meeting was organised by Hugues Chap (INSERM U 326, Toulouse, France), Georges Ferard (University of Strasbourg, France), Wolfgang Junge (University of Kiel, Germany) and Michael Mackness (University of Manchester, UK). In recent years it has become increasingly apparent that hydrolytic enzymes of the esterase, lipase and phospholipase type play central roles in the pathophysiology of many human diseases. The purpose of this NATO-ARW was to bring together experts (both clinical and scientific) in all three interrelated fields to review the current basic and clinical position and discuss future developments particularly with respect to future research aimed at determining the basic biochemical lesion involving hydrolytic enzymes involved in human disease and the use of these enzymes in diagnosis. As well as formal lectures from established researchers, the meeting also involved a number of lively round-table discussions on future developments and presentations from younger research workers, all of which are recorded in this Proceedings and which contribute to the success of the meeting.…

This item is printed on demand - it takes 3-4 days longer - Neuware -In contrast to the great diversity of other crime and delinquency research measures, those drawn from the CPI and the MMPI have much in common. They are taken from standardized instruments administered under controlled conditions, with known stimulus properties and validity indicators. The CPI and MMPI measures will frequently be instruments of choice in research on personality and psychodynamics of offenders. CHAPTER 6 Law Enforcement and Police This chapter encompasses a variety of scales that refer to law enforcement or police agencies. Unfortunately, in the case of many scales, these terms are used simply with the assumption that the respondents understand the concepts and use them in the same way as researchers. In other cases, however, specific policing functions are identified and described. As noted in Chapter 3, a standard order of scale presentation is followed. First the attitudes scales are presented, followed by the behavior ratings, per sonality measures, milieu ratings, prediction measures and finally the very broad category of description. After the reviews are completed within each subcategory, other scales in that category are listed. (See Chapter 2 for a description of the criteria that were used in deciding upon whether a scale would be reviewed or simply listed. ) Listed scales are presented by title and bibliographic reference, followed by a very brief description. 644 pp. Englisch.…

This item is printed on demand - it takes 3-4 days longer - Neuware -During the past two decades, a significant international research effort has been di rected toward understanding the composition and regulation of the preocular tear film. This effort has been motivated by the recognition that the tear film plays an essential role in maintaining corneal and conjunctival integrity, protecting against microbial challenge, and preserving visual acuity. In addition, research has been stimulated by the knowledge that alteration or deficiency of the tear film, which occurs in countless individuals throughout the world, may lead to desiccation of the ocular surface, ulceration and perfo ration of the cornea, an increased incidence of infectious disease, and, potentially, pro nounced visual disability and blindness. To promote further progress in this field of vision research, the Second International Conference on the Lacrimal Gland, Tear Film and Dry Eye Syndromes: Basic Science and Clinical Relevance was held at the Southampton Princess Resort in Bermuda November 16-19, 1996. This conference was organized and directed by David A. Sullivan, Ph. D. , codirected by Darlene A. Dartt, Ph. D. , and Michele A. Meneray, Ph. D. , and sponsored by the Schepens Eye Research Institute (Boston, MA), an affiliate of Harvard Medical School. The meeting was designed to assess critically the current knowledge and 'state of the art' research on the structure and function of lacrimal tissue, tears, and the ocular sur face in both health and disease. 1108 pp. Englisch.…

Taschenbuch. Condición: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -Activity in any theoretical area is usually stimulated by new experimental techniques and the resulting opportunity of measuring phenomena that were previously inaccessible. Such has been the case in the area under consideration here beginning about fifteen years ago when the possibility of studying chemical reactions in crossed molecular beams captured the imagination of physical chemists, for one could imagine investigating chemical kinetics at the same level of molecular detail that had previously been possible only in spectroscopic investigations of molecular stucture. This created an interest among chemists in scattering theory, the molecular level description of a bimolecular collision process. Many other new and also powerful experimental techniques have evolved to supplement the molecular beam method, and the resulting wealth of new information about chemical dynamics has generated the present intense activity in molecular collision theory. During the early years when chemists were first becoming acquainted with scattering theory, it was mainly a matter of reading the physics literature because scattering experiments have long been the staple of that field. It was natural to apply the approximations and models that had been developed for nuclear and elementary particle physics, and although some of them were useful in describing molecular collision phenomena, many were not. The most relevant treatise then available to students was Mott and Massey's classic The Theory of Atomic Collisions, \* but, as the title implies, it dealt only sparingly with the special features that arise when at least one of the collision partners is a molecule. 336 pp. Englisch.…

Taschenbuch. Condición: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -Volume 6 of Developments in Applied Spectroscopy presents a collection of twenty-eight selected papers from those that were pre sented at the Eighteenth Mid-America Symposium on Spectroscopy held in Chicago, May 15 to 18, 1967. In general, the papers selected by the editors are those of the symposium type and not those papers pertaining to a specific research topic that one expects to be sub mitted to a journal. Not all of the submitted papers were included. Some revisions could not meet the deadline and others were not accepted based on the advice of the reviewers. It is the opinion of the committee that this type of publication has an important place in the literature. The Mid-America Symposium is sponsored annually by the Chicago Section in cooperation with the Cincinnati, Detroit, Indianapolis, Milwaukee, Niagara Frontier, and St. Louis Sections of the Society of Applied Spectroscopy, and the Chicago Gas Chromatography Group. Although the Mid-America is often thought of as a regional meeting, its attendees and authors generally come from all parts of the United States and Canada. Both applied and theoretical principles were provided in sessions on X-ray, emission, atomic-absorption, nuclear magnetic resonance, infrared, Raman, nuclear-particle, and gamma ray spectroscopy; activation analysis; and gas chromatography. In addition, there were symposia on absorption spectra of biologically significant molecules; the structure of ice, water, and aqueous solu tions; air and water pollution analyses; and the practical application of statistics. 416 pp. Englisch.…

This item is printed on demand - it takes 3-4 days longer - Neuware -It would have been difficult at the beginning of the 80's to have predicted that by the end of the decade, Medical Virology would have become one of the most important topics in the area of both basic and clinical research. Although we were expecting a progressive increase in awareness of the role played by viruses in different diseases, we did not expect the outbreak of a fatal disease that was going to shake the roots of our society. The appearance of the human immunodeficiency virus (HIV-1) in the early 80's, has prompted a unique re search impetus in the area of Medical Virology. The knowledge that we are gaining in our attempt to understand the biology of HIV-1 and the immuno logical response to this virus should not only help us control the spread of this virus, but should also help us to better understand other viral infections. Let us hope that during the 1990's we can learn how to control HIV-1 infections so that by the end of the decade, no more human lives succumb to an infection with this virus.

Taschenbuch. Condición: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -As was shown in the first two volumes of this series, great strides have been made in identifying many of the agents or classes of substances responsible for carcinogenesis and in delineating their interactions with the cell. Clearly, the aim of such studies is that, once identified, these agents can be eliminated from the environment. Yet, despite these advances and the elimination of some important carcinogenic agents, one major problem exists. It is a constant monitor of all oncologic study and diminishes the importance of every experiment and of every clinical observation. As we noted earlier, that problem is our inability to define the malignant cell. It is through studies of the fundamental biology of tumors that we seek this definition. A vast amount of information has been gathered which describes what this cell does and-to a lesser extent-how it does it. But the why evades us. We have been unable to define the malignant cell, save in broad terms by comparing it to its normal counterpart. The major problem appears to be that the malignant cell does so much. It is a chimera, mystifyingly composed of normal activities and structures, of phenotypic schizophrenia with embryonic, fetal, and adult charac teristics and, occasionally, a hint of an unclassifiable capacity unique to malignant cells. 456 pp. Englisch.…

This item is printed on demand - it takes 3-4 days longer - Neuware -In the first half of this century, great strides were made in under standing the behavior of polymers in dilute solutions or in the solid state. Concentrated solutions, on the other hand, were commonly regarded as mainly of interest to practitioners, being too complex for the rigorous application of statistical theory. Given the preoccupation with the isolated polymer molecule and the attendant focus on the state of infinite dilution, it is not surprising that aggregation, and inter-polymer associ ation in general, was the bugaboo of experimentalists. These attitudes have changed remarkably over the last few decades. The application of sealing theory to polymer solutions has stimulated investigation of the semi-dilute state, and the region between infinite dilution and swollen gel is no longer perceived as terra incognita. New techniques, such as dynamic light scattering, have proven to be of much value in such investigations. At the same time, it has become clear that consideration of strong inter- and intra-polymer forces, superimposed on the familiar description of the statistical chain, is prerequisite to the application of polymer science to numerous systems of interest. Para mount among these, of course, are biopolymers, their complexes and assemblies. The isolated random coil must be viewed as tl rarity in nature. 476 pp. Englisch.…

The Mid-America Symposium is sponsored annually by the Chicago Section of the Society for Applied Spectroscopy, in cooperation with the St. Louis, Niagara Frontier, Cleveland, Detroit, Indianapolis, and Milwaukee sections of the Society and the Chicago Gas Chromatography Discussion Group. Although basically a regional meeting, the Symposium continues to draw enthusiastic attendance from coast to coast and numerous foreign countries. The present volume contains 45 of the 110 papers presented at the Symposium. It is with some misgiving that we offer this volume as the proceedings of the meeting with less than half of the total papers included. However, it is the opinion of the Symposium Committee that publication of the excellent material available from the Symposium provides a valuable addition to the literature in the field of spectroscopy. Response to previous volumes of this series seems to verify this opinion. As Chairman of the Symposium and Editor of this volume, I express my sincere appreciation to the authors whose manuscripts make up this volume.

Taschenbuch. Condición: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -These proceedings contain the papers presented during the 14th annual High Energy Physics meeting convened under the aegis of Orbis Scientiae 1977. The title 'Deeper Pathways in High Energy Physics' was adopted to indicate either further penetration into the nature of the structure of the elementary particle or the deepening of the continuously trodden path that gets gradually deeper and deeper, evolving into a trench. In the latter instance, the visibility of the real nature of elementary particles may be getting dimmer and dimmer. It is hoped that some of the papers in these proceedings do, indeed, contain further revelations on the 'deeper' nature of elementary particles. We must not be overly charmed with 'charm' even if it may fit the data of the current generation of e+ and e experiments. It would be much less than prophetic to say that a complete and totally satisfactory theory com~ising the entire physical reality is yet to be discovered, and there is presumably no paper of that kind in these proceedings. Despite this short coming, the editors do not wish to hide their admiration for the caliber of the papers contributed by the participants of Orbis Scientiae 1977. Appreciation is extended to Mrs. Helga S. Billings, Mrs. Elva Brady, and Ms. Yvonne L.
