Book Description
The challenge of communication in planetary exploration has been unusual. The guidance and control of spacecraft depend on reliable communication. Scientific data returned to earth are irreplaceable, or replaceable only at the cost of another mission. In deep space, communications propagation is good, relative to terrestrial communications, and there is an opportunity to press toward the mathematical limit of microwave communication. Yet the limits must be approached warily, with reliability as well as channel capacity in mind. Further, the effects of small changes in the earth's atmosphere and the interplanetary plasma have small but important effects on propagation time and hence on the measurement of distance. Advances are almost incredible. Communication capability measured in 18 bits per second at a given range rose by a factor of 10 in the 19 years from Explorer I of 1958 to Voyager of 1977. This improvement was attained through ingenious design based on the sort of penetrating analysis set forth in this book by engineers who took part in a highly detailed and amazingly successful pro gram. Careful observation and analysis have told us much about limitations on the accurate measurement of distance. It is not easy to get busy people to tell others clearly and in detail how they have solved important problems. Joseph H. Yuen and the other contribu tors to this book are to be commended for the time and care they have devoted to explicating one vital aspect of a great adventure of mankind.

Book Description
The positive benefits of physical activity for physical and mental health are now widely acknowledged, yet levels of physical inactivity continue to be a major concern throughout the world. Understanding the psychology of physical activity has therefore become an important issue for scientists, health professionals and policy-makers alike as they address the challenge of behaviour change. Psychology of Physical Activity provides comprehensive and in-depth coverage of the fundamentals of exercise psychology, from mental health, to theories of motivation and adherence, and to the design of successful interventions for increasing participation. Now publishing in a fully revised, updated and expanded fourth edition, Psychology of Physical Activity is still the only textbook to offer a full survey of the evidence base for theory and practice in exercise psychology, and the only textbook that explains how to interpret the quality of the research evidence. As the field continues to grow rapidly, the new edition expands the behavioural science content of numerous important topics, including physical activity and cognitive functioning, automatic and affective frameworks for understanding physical activity involvement, new interventions designed to increase physical activity (including use of new technologies), and sedentary behaviour. A full companion website offers useful features to help students and lecturers get the most out of the book during their course, including multiple-choice revision questions, PowerPoint slides and a test bank of additional learning activities. Psychology of Physical Activity is the most authoritative, engaging and up-to-date book on exercise psychology currently available. It is essential reading for all students working in behavioural medicine, as well as the exercise and health sciences.

Book Description
Social problems in many domains, including health, education, social relationships, and the workplace, have their origins in human behavior. The documented links between behavior and social problems have compelled governments and organizations to prioritize and mobilize efforts to develop effective, evidence-based means to promote adaptive behavior change. In recognition of this impetus, The Handbook of Behavior Change provides comprehensive coverage of contemporary theory, research, and practice on behavior change. It summarizes current evidence-based approaches to behavior change in chapters authored by leading theorists, researchers, and practitioners from multiple disciplines, including psychology, sociology, behavioral science, economics, philosophy, and implementation science. It is the go-to resource for researchers, students, practitioners, and policy makers looking for current knowledge on behavior change and guidance on how to develop effective interventions to change behavior.

Book Description
SIMS' SYMPTOMS IN THE MIND has, since its first publication in 1988, become established as the leading introductory textbook on clinical psychopathology. This new edition has been fully updated to include advances in neuropsychology and cognitive neuroscience and changes can be found in the chapters on memory disturbance, disorders of time, pathology of perception, disorders of speech and language, affect and emotional disorders, and disorders of volition and execution. In some cases, novel classifications of the abnormalities under consideration have been provided together with additional pathological phenomena - including palinopsia, akinetopsia, zeitraffer phenomenon, exosomesthesia - many of which have been rediscovered or imported from neurology. The popular and distinctive features are the use of figures, tables and illustrative case examples which have been further enhanced with additional case examples from the classical literature, autobiographical narratives and fiction. New section headings provide firmer thematic unity to the content Check boxes summarize important points such as classification of particular areas Additional examples of psychopathology are included which are drawn from a wide source including fiction, autobiography and clinical textbooks Includes an extended range of abnormalities, including those which have previously been neglected, such as alloaesthesia, palinaptia, teleopsia, pelopsia, akinetopsia, palinopsia, and paraprosopia Fully updated description of the theoretical aspects of memory and its disturbance Fully integrated neuropsychological concepts of imagery and internal mental representations in the chapter on abnormalities of perception

Book Description
Before AIDS, the role of behavioral interventions in preventing transmission of sexually transmitted diseases was acknowledged in text books and journals but rarely promoted effectively in public health practice. This book addresses the complexities and social contexts of human behaviors which spread STDs, the cultural barriers to STD education, and the sociopolitical nuances surrounding treatment.

Book Description
Reflecting a decade’s worth of changes, Human Safety and Risk Management, Second Edition contains new chapters addressing safety culture and models of risk as well as an extensive re-working of the material from the earlier edition. Examining a wide range of approaches to risk, the authors define safety culture and review theoretical models that elucidate mechanisms linking safety culture with safety performance. Filled with practical examples and case studies and drawing on a range of disciplines, the book explores individual differences and the many ways in which human beings are alike within a risk and safety context. It delineates a risk management approach that includes a range of techniques such as risk assessment, safety audit, and safety interventions. The authors address concepts central to workplace safety such as attitudes and their link with behavior. They discuss managing behavior in work environments including key functions and benefits of groups, factors influencing team effectiveness, and barriers to effectiveness such as groupthink.

Book Description
This well-illustrated book is a comprehensive guide to the cutaneous clinical presentations of mycobacterial infections. The Mycobacterium genus includes over 170 species, nontuberculous mycobacteria (NTM) having been added to the obligate human pathogens such as M. tuberculosis and M. leprae. NTM are widely distributed in the environment with high isolation rates worldwide; the skin is a major target with variable clinical manifestations. A current resurgence in tuberculosis is aggravated by the synergy with human immunodeficiency virus, the breakdown of health care systems, and the rise in multidrug-resistant disease, as the incidence of leprosy remains stable, at around 250,000 new cases annually, regardless of effective antibiotic therapy. Presentations of various cutaneous infections caused by mycobacteria may be overlooked by clinicians owing the lack of familiarity with tuberculosis, leprosy, and the related NTM clinical features. This handy guide will help the dermatologist to spot the different clinical manifestations, make a prompt diagnosis, and apply effective treatment.
