What is light? Where are optics and photonics present in our lives and in nature? What lies behind different optical phenomena? What is an optical instrument? How does the eye resemble an optical instrument? How can we explain human vision? This book, written by a group of young scientists, answers these questions and many more.

Dennis Dalton's classic account of Gandhi's political and intellectual development focuses on the leader's two signal triumphs: the civil disobedience movement (or salt satyagraha) of 1930 and the Calcutta fast of 1947. Dalton clearly demonstrates how Gandhi's lifelong career in national politics gave him the opportunity to develop and refine his ideals. He then concludes with a comparison of Gandhi's methods and the strategies of Martin Luther King Jr. and Malcolm X, drawing a fascinating juxtaposition that enriches the biography of all three figures and asserts Gandhi's relevance to the study of race and political leadership in America. Dalton situates Gandhi within the "clash of civilizations" debate, identifying the implications of his work on continuing nonviolent protests. He also extensively reviews Gandhian studies and adds a detailed chronology of events in Gandhi's life.

The Government and authorities in Brazil were faced with a tragic accident in Goiânia resulting from the misuse of a strongly radioactive medical teletherapy source not under radiation protection surveillance. The present report is divided into four parts: a chronology of destruction of the source, discovery of the accident and initial response; a description of the human consequences and the dosimetry and treatment of seriously exposed and contaminated persons; an account of the assessment of the environmental contamination and the remedial actions taken; and observations and recommendations. Appendices and annexes give an assessment of the effectiveness of international co-operation in the emergency response, and provide further information on: public communications; radiological survey equipment; guidelines for the discharge of patients; radiological protection; chemical decontamination; and the lessons learned.

Since its inception, anthropology's authority has been based on the assumption that it is a unified discipline emanating from the West. In an age of heightened globalization, anthropologists have failed to discuss consistently the current status of their practice and its mutations across the globe. World Anthropologies is the first book to provoke this conversation from various regions of the world in order to assess the diversity of relations between regional or national anthropologies and a contested, power-laden Western discourse. Can a planetary anthropology cope with both the 'provincial cosmopolitanism' of alternative anthropologies and the 'metropolitan provincialism' of hegemonic schools? How might the resulting 'world anthropologies' challenge the current panorama in which certain allegedly national anthropological traditions have more paradigmatic weight - and hence more power - than others? Critically examining the international dissemination of anthropology within and across national power fields, contributors address these questions and provide the outline for a veritable world anthropologies project.

"Here is a 'must-read' for all health promotion researchers and practitioners eager to stay one step ahead of the pack. A panoply of insightful and promising new approaches is presented for consideration and exploration in our contemporary behavioral science arsenal." — M. Elaine Auld, MPH, CHES, Chief Executive Officer, Society for Public Health Education "This book is an essential addition to the health practice and research literature, concentrating on theories that have not been extensively covered elsewhere and that have great currency. It provides an up-to-date rendition on the interplay among contemporary public health concerns, sound public health practice, and the theoretical bases for practice."— Robert M. Goodman, PhD, MPH, Dean and Professor, School of Health, Physical Education, and Recreation, Indiana University "The authors of Emerging Theories provide vivid descriptions of the state of the science in health promotion and presents an exciting map for future research. Understanding and using theories is the hallmark of an excellent practitioner. Creating and elaborating theories is the mark of an excellent researcher. This text will be very valuable for both." — Noreen M. Clark, PhD, Myron E. Wegman Distinguished University Professor; Director, Center for Managing Chronic Disease, University of Michigan "Emerging Theories captures the dynamic growth in theories of health promotion and illustrates how divergent theoretical perspectives are being integrated into richer explanatory and practice models." — Matthew W. Kreuter, PhD, MPH, Professor of Social Work and Medicine; Director, Health Communication Research Laboratory, Washington University in St. Louis
