Vaughan unveils the complicated and high-pressure world of air traffic controllers as they navigate technology and political and public climates, and shows how they keep the skies so safe. When two airplanes were flown into the World Trade Center towers on September 11, 2001, Americans watched in uncomprehending shock as first responders struggled to react to the situation on the ground. Congruently, another remarkable and heroic feat was taking place in the air: more than six hundred and fifty air traffic control facilities across the country coordinated their efforts to ground four thousand flights in just two hours—an achievement all the more impressive considering the unprecedented nature of the task. In Dead Reckoning, Diane Vaughan explores the complex work of air traffic controllers, work that is built upon a close relationship between human organizational systems and technology and is remarkably safe given the high level of risk. Vaughan observed the distinct skill sets of air traffic controllers and the ways their workplaces changed to adapt to technological developments and public and political pressures. She chronicles the ways these forces affected their jobs, from their relationships with one another and the layouts of their workspace to their understanding of their job and its place in society. The result is a nuanced and engaging look at an essential role that demands great coordination, collaboration, and focus—a role that technology will likely never be able to replace. Even as the book conveys warnings about complex systems and the liabilities of technological and organizational innovation, it shows the kinds of problem-solving solutions that evolved over time and the importance of people.

This new volume in the Encyclopaedia of Sports Medicine series, published under the auspices of the International Olympic Committee, provides a state-of-the- art account of the epidemiology of injury across a broad spectrum of Olympic sports. The book uses the public health model in describing the scope of the injury problem, the associated risk factors, and in evaluating the current research on injury prevention strategies described in the literature. Epidemiology of Injury in Olympic Sports comprehensively covers what is known about the distribution and determinants of injury and injury rates in each sport. The editors and contributors have taken an evidence-based approach and adopted a uniform methodology to assess the data available. Each chapter is illustrated with tables which make it easy to examine injury factors between studies within a sport and between sports. With contributions from internationally renowned experts, this is an invaluable reference book for medical doctors, physical therapists and athletic trainers who serve athletes and sports teams, and for sports medicine scientists and healthcare professionals who are interested in the epidemiological study of injury in sports.

e-Learning Ecologies explores transformations in the patterns of pedagogy that accompany e-learning—the use of computing devices that mediate or supplement the relationships between learners and teachers—to present and assess learnable content, to provide spaces where students do their work, and to mediate peer-to-peer interactions. Written by the members of the "new learning" research group, this textbook suggests that e-learning ecologies may play a key part in shifting the systems of modern education, even as technology itself is pedagogically neutral. The chapters in this book aim to create an analytical framework with which to differentiate those aspects of educational technology that reproduce old pedagogical relations from those that are genuinely innovative and generative of new kinds of learning. Featuring case studies from elementary schools, colleges, and universities on the practicalities of new learning environments, e-Learning Ecologies elucidates the role of new technologies of knowledge representation and communication in bringing about change to educational institutions.

The myth of the peace-loving "noble savage" is persistent and pernicious. Indeed, for the last fifty years, most popular and scholarly works have agreed that prehistoric warfare was rare, harmless, unimportant, and, like smallpox, a disease of civilized societies alone. Prehistoric warfare, according to this view, was little more than a ritualized game, where casualties were limited and the effects of aggression relatively mild. Lawrence Keeley's groundbreaking War Before Civilization offers a devastating rebuttal to such comfortable myths and debunks the notion that warfare was introduced to primitive societies through contact with civilization (an idea he denounces as "the pacification of the past"). Building on much fascinating archeological and historical research and offering an astute comparison of warfare in civilized and prehistoric societies, from modern European states to the Plains Indians of North America, War Before Civilization convincingly demonstrates that prehistoric warfare was in fact more deadly, more frequent, and more ruthless than modern war. To support this point, Keeley provides a wide-ranging look at warfare and brutality in the prehistoric world. He reveals, for instance, that prehistorical tactics favoring raids and ambushes, as opposed to formal battles, often yielded a high death-rate; that adult males falling into the hands of their enemies were almost universally killed; and that surprise raids seldom spared even women and children. Keeley cites evidence of ancient massacres in many areas of the world, including the discovery in South Dakota of a prehistoric mass grave containing the remains of over 500 scalped and mutilated men, women, and children (a slaughter that took place a century and a half before the arrival of Columbus). In addition, Keeley surveys the prevalence of looting, destruction, and trophy-taking in all kinds of warfare and again finds little moral distinction between ancient warriors and civilized armies. Finally, and perhaps most controversially, he examines the evidence of cannibalism among some preliterate peoples. Keeley is a seasoned writer and his book is packed with vivid, eye-opening details (for instance, that the homicide rate of prehistoric Illinois villagers may have exceeded that of the modern United States by some 70 times). But he also goes beyond grisly facts to address the larger moral and philosophical issues raised by his work. What are the causes of war? Are human beings inherently violent? How can we ensure peace in our own time? Challenging some of our most dearly held beliefs, Keeley's conclusions are bound to stir controversy.
