The promotion of CCTV surveillance and identity cards, along with ever heightened security at airports, immigration control and institutional access, has seen a dramatic increase in the use of automated and manual recognition. In addition, several recent disasters have highlighted the problems and challenges associated with current disaster victim identification. Discussing the latest advances and key research into identification from the face and skull, this book draws together a wide range of elements relating to craniofacial analysis and identification. It examines all aspects of facial identification, including the determination of facial appearance from the skull, comparison of the skull with the face and the verification of living facial images. With sections covering the identification of the dead and of the living, it provides a valuable review of the current state of play along with the latest research advances in this constantly evolving field.

This book describes how malaria both frustrates and facilitates life for Indigenous Pa lawan communities living in the forested foothills of the municipality of Bataraza on the island of Palawan in the Philippines. Tracing the arc of malaria on the archipelago from colonial encounters to the present day, it examines the ways in which malaria parasites have become entangled in contemporary lives. It uniquely explores the experiences of local government leaders working towards sustainably developing this last ecological frontier, health workers trying to meet international targets to eliminate malaria, and Pa lawan people trying to keep their bodies, social relations and the cosmos in careful balance. In exquisite detail, Dr Dalia Iskander shows how malaria emerged from, and was intrinsic to, a whole host of strategically-orientated social practices that were enacted in as well as around the disease's name, as people worked day-to-day to gain power in different guises in different arenas.

The discovery of the first species of African hominin, Australopithecus africanus, from Taung, South Africa in 1924, launched the study of fossil man in Africa. New discoveries continue to confirm the importance of this region to our understanding of human evolution. Outlining major developments since Raymond Dart's description of the Taung skull and, in particular, the impact of the pioneering work of Phillip V. Tobias, this book will be a valuable companion for students and researchers of human origins. It presents a summary of the current state of palaeoanthropology, reviewing the ideas that are central to the field, and provides a perspective on how future developments will shape our knowledge about hominin emergence in Africa. A wide range of key themes are covered, from the earliest fossils from Chad and Kenya, to the origins of bipedalism and the debate about how and where modern humans evolved and dispersed across Africa.

This book, originally published in 2004, is concerned with the links between human evolution and infectious disease. It has long been recognised that an important factor in human evolution has been the struggle against infectious disease and, more recently, it was revealed that complex genetic polymorphisms are the direct result of that struggle. As molecular biological techniques become more sophisticated, a number of breakthroughs in the area of host-pathogen evolution led to an increased interest in this field. From the historical beginnings of J. B. S. Haldane's original hypothesis to more recent research, this book strives to evaluate infectious diseases from an evolutionary perspective. It provides a survey of information regarding host-pathogen evolution related to major infectious diseases and parasitic infections, including malaria, influenza and leishmaniasis. Written by leading authorities in the field, and edited by a former pupil of Haldane, Infectious Disease and Host-Pathogen Evolution will be valuable for those working in related areas of microbiology, parasitology, immunology and infectious disease medicine, as well as genetics, evolutionary biology and epidemiology.

Dr Taylor's book analyses the disease concept as it developed in medical history and seeks to clarify it with the help of concepts largely derived from logical class theories. A solution is proposed to the problem of how to distinguish between the class of 'patients' and the class of 'healthy persons' which corresponds to the actual diagnostic practices of doctors. The earliest theories of disease postulated concrete entities which exist independently of the body. The notion of disease entity has lost its original ontological connotations and instead its important feature has become the possession of a unitary and self-contained character. Dr Taylor describes the modern theories as essentially 'reactive' in character, that is the symptoms of a disease are the bodily reactions to the 'noxae'. After seeing the subject in its historical content, Dr Taylor goes on to discuss in detail the notion of the classification of diseases, making extensive use of modern views on the logic of classes.

Measures of biological variation have long been associated with many indices of social inequality. Data on health, nutrition, fertility, mortality, physical fitness, intellectual performance and a range of heritable biological markers show the ubiquity of such patterns across time, space and population. This volume reviews the current evidence for the strength of such linkages and the biological and social mechanisms that underlie them. A major theme is the relationship between the proximate determinants of these linkages and their longer-term significance for biologically selective social mobility. This book therefore addresses the question of how social stratification mediates processes of natural selection in human groups. Data like this pose difficult and sensitive issues for health policy and developments in this area and in eugenics are reviewed for industrialised and developing countries.

Bringing together a variety of today's most accomplished dental researchers Technique and Application in Dental Anthropology covers a range of topics germane to the study of human and other primate teeth. The chapters encompass work on individuals to samples, ranging from prehistoric to modern times. The focus throughout the book is the methodology required for the study of modern dental anthropology, comprising the most up-to-date scientific methods in use today - ranging from simple observation to advanced computer-based analyses - which can be utilized by the reader in their own dental research. Originating from the 20th anniversary meeting of the Dental Anthropology Association, this is a valuable reference source for graduate students, academic researchers and professionals in the social and life sciences, as well as clinicians.

As a group, western diseases such as type 2 diabetes, cardiovascular disease, breast cancer, allergies and mental health problems constitute one of the major problems facing humans at the beginning of the 21st century, particularly as they extend into poorer countries. An evolutionary perspective has much to offer standard biomedical understandings of western diseases. At the heart of this approach is the notion that human evolution occurred in circumstances very different from the modern affluent western environment and that, as a consequence, human biology is not adapted to the contemporary western environment. Written with an anthropological perspective and aimed at advanced undergraduates and graduates taking courses in the ecology and evolution of disease, Tessa Pollard applies and extends this evolutionary perspective by analysing trends in rates of western diseases and providing a new synthesis of current understandings of evolutionary processes, and of the biology and epidemiology of disease.

The Earth's biodiversity-the rich variety of life on our planet-is disappearing at an alarming rate. And while many books have focused on the expected ecological consequences, or on the aesthetic, ethical, sociological, or economic dimensions of this loss, Sustaining Life is the first book to examine the full range of potential threats that diminishing biodiversity poses to human health.
Edited and written by Harvard Medical School physicians Eric Chivian and Aaron Bernstein, along with more than 100 leading scientists who contributed to writing and reviewing the book, Sustaining Life presents a comprehensive--and sobering--view of how human medicines, biomedical research, the emergence and spread of infectious diseases, and the production of food, both on land and in the oceans, depend on biodiversity. The book's ten chapters cover everything from what biodiversity is and how human activity threatens it to how we as individuals can help conserve the world's richly varied biota. Seven groups of organisms, some of the most endangered on Earth, provide detailed case studies to illustrate the contributions they have already made to human medicine, and those they are expected to make if we do not drive them to extinction. Drawing on the latest research, but written in language a general reader can easily follow, Sustaining Life argues that we can no longer see ourselves as separate from the natural world, nor assume that we will not be harmed by its alteration. Our health, as the authors so vividly show, depends on the health of other species and on the vitality of natural ecosystems.
With a foreword by E.O. Wilson and a prologue by Kofi Annan, and more than 200 poignant colorillustrations, Sustaining Life contributes essential perspective to the debate over how humans affect biodiversity and a compelling demonstration of the human health costs.

Andrea Wiley investigates the ecological, historical, and socio-cultural factors that contribute to the peculiar pattern of infant mortality in Ladakh, a high-altitude region in the western Himalayas of India. Ladakhi newborns are extremely small at birth, smaller than those in other high-altitude populations, smaller still than those in sea level regions. Factors such as hypoxia, dietary patterns, the burden of women's work, gender, infectious diseases, seasonality, and use of local health resources all affect a newborn's birth weight and raise the likelihood of infant mortality. An Ecology of High-Altitude Infancy is unique in that it makes use of the methods of human biology but strongly emphasizes the ethnographic context that gives human biological measures their meaning. It is an example of a new genre of anthropological work: 'ethnographic human biology'.

Based on international research, this collection incorporates a critical analysis of World Health Organization cross-cultural findings. Contributors share an interest in subjective and interpretive aspects of illness, while maintaining the concept of schizophrenia that addresses its biological aspects. The volume is of interest to scholars in the social and human sciences, and of practical relevance not only to psychiatrists, but all mental health professionals encountering the clinical problems bridging culture and psychosis.

When Mary Steedly went to North Sumatra, Indonesia, she intended to study the curing practices of Karo Batak spirit mediums, the gurus who keep a community in touch with its ancestors. She became fascinated by the stories these women and men told of their encounters with spirits in the ritual arena and on the borders of the everyday social world. In these stories, Karo mediums conveyed their sense of historical out-of-placeness, which they described as "hanging without a rope," in Indonesia's state-proclaimed Age of Development. Based on the author's three years of fieldwork in urban and rural Karoland, this engaging and sympathetic account focuses on issues of experience, memory, and narrative plausibility. Steedly approaches mediums' stories not simply as reservoirs of information about "what happened" at a particular moment, but as interested efforts to map a pathway across the shifting landscape of historical memory. Over the past century Karoland has been the scene of colonial conquest, Christian conversion, commercial agricultural development, military occupation, reolution, migration, and modernization. Storeis of spirit encounters, Steedly argues, provide an alternative, "unofficial" perspective on the historical transformation of the Karo social world. In addition to her rich ethnographic material, she draws on feminist theories of subjectivity, William Faulkner's reconstructions of personal and collective memory, and current anthropological explorations of the politics of representation to open the ethnographic imagination to historical eventfulness. Mary Margaret Steedly is Assistant Professor of Anthropology at Harvard University. Originally published in 1993. The Princeton Legacy Library uses the latest print-on-demand technology to again make available previously out-of-print books from the distinguished backlist of Princeton University Press. These editions preserve the original texts of these important books while presenting them in durable paperback and hardcover editions. The goal of the Princeton Legacy Library is to vastly increase access to the rich scholarly heritage found in the thousands of books published by Princeton University Press since its founding in 1905.

There is growing interest in "therapeutic narratives" and the relation between narrative and healing. Cheryl Mattingly's ethnography of the practice of occupational therapy in a North American hospital investigates the complex interconnections between narrative and experience in clinical work. Viewing the world of disability as a socially constructed experience, it presents fascinatingly detailed case studies of clinical interactions between occupational therapists and patients, many of them severely injured and disabled, and illustrates the diverse ways in which an ordinary clinical interchange is transformed into a dramatic experience governed by a narrative plot. Drawing on a wide range of sources, including anthropological studies of narrative and ritual, literary theory, phenomenology and hermeneutics, this book develops a narrative theory of social action and experience. While most contemporary theories of narrative presume that narratives impose an artificial coherence upon lived experience, Mattingly argues for a revision of the classic mimetic position. If narrative offers a correspondence to lived experience, she contends, the dominant formal feature which connects the two is not narrative coherence but narrative drama. Moving and sophisticated, this book is an innovative contribution to the study of modern institutions and to anthropological theory.

The biological and neurological capacity to symbolize, and the products of behavioral, cognitive, sociocultural, linguistic, and technological uses of symbols (symbolism), are fundamental to every aspect of human life. The Oxford Handbook of Human Symbolic Evolution explores the origins of our characteristically human abilities - our ability to speak, create images, play music, and read and write. The book investigates how symbolization evolved in human evolution and how symbolism is expressed across the various areas of human life. The field is intrinsically interdisciplinary - considering findings from fossil studies, scientific research from primatology, developmental psychology, and of course linguistics. Written by world leading experts, thirty-nine topical chapters are grouped into six thematic parts that respectively focus on epistemological, psychological, anthropological, ethological, linguistic, and social-technological aspects of human symbolic evolution. The handbook presents an in-depth but comprehensive and interdisciplinary overview of the of the state of the art in the science of human symbolic evolution. This work will be of interest to academics and students active in all fields contributing to the study of human evolution.

It is estimated that up to thirteen percent of hospital admissions result from the adverse effects of diagnosis or treatment, and that anywhere from 44,000 to 98,000 hospital deaths annually are the result of errors. The obligation to "do no harm" has been central to medical conduct since ancient times, yet iatrogenic illness and medical error have now come to be recognized as significant risk factors in health care delivery. This book integrates history, philosophy, medical ethics and empirical data to examine the concept and phenomenon of medical harm. Issues covered include medical error, appropriateness of care, acceptable risk and practitioner accountability, and recommendations for limiting iatrogenic harm.

This book discusses the various social, political, and cultural forces that shape the distribution of diseases in populations. It is based on a series of comparative studies of the historical and contemporary disease patterns of the indigenous peoples of America north of Mexico, Polynesia, and Australia. The purpose of the comparisons is to control in a quasi-experimental way certain crucial variables in order to examine the impact on health of other variables. The comparisons are made at increasingly more refined levels of analysis. Thus, once disease ecology has been held roughly constant, one can see more clearly the ways in which colonial policy and political institutions have shaped the affairs of indigenous peoples. And once policy has been held constant, one can see more clearly how culture can make a difference. And once culture has been held constant, one can see how gender and status make a difference.
Kunitz argues that very few broad generalizations adequately explain the distribution of diseases in populations and that to truly comprehend such patterns one must understand the local social context as well the biological characteristics of diseases. The book is thus an argument for the importance of local knowledge as a complement to the universalizing sort of knowledge that we associate with science.

Medical anthropology encompasses a wide range of perspectives as it seeks to understand human health and illness. An ideal core text for introductory courses, Medical Anthropology: A Biocultural Approach provides a current and accessible overview of this diverse and rapidly expanding field. Working from a iocultural approach, Medical Anthropology examines the major health issues that affect most human societies, describing and synthesizing the ways in which biology, culture, health, and environment interact. It integrates up-to-date and relevant biological data with analyses of both evolutionary theory and the sociocultural conditions that often lead to major challenges to our health and survival.
Authors Andrea S. Wiley and John S. Allen first present basic biological information on a specific health condition and then extend their investigation to include evolutionary, historical, sociocultural, and political-economic perspectives. Topics covered include healers and healing; health, diet, and nutrition; child health, growth, and development; reproductive health; aging; infectious disease; behavioral disease; stress, social inequality, and race; and mental illness. Each chapter features a variety of case studies and examples--current and historical, local and global--that demonstrate how a medical anthropological perspective can shed important light on a particular health condition. In addition, the text is enhanced by numerous tables, figures, review questions, critical thinking questions, suggestions for accompanying ethnographies, and a glossary to help students better understand the material. Throughout the text, the authors consider how a biocultural anthropological approach could be applied to more effective prevention and treatment efforts. They also highlight the ways in which medical anthropology has the potential to help improve the health of populations around the world.

Surrealist writer Andre Breton praised hysteria for being the greatest poetic discovery of the nineteenth century, but many physicians have since viewed it as the "wastebasket of medicine," a psychosomatic state that defies attempts at definition and cure and that can be easily mistaken for other pathological conditions. In light of a resurgence of critical interest in hysteria, leading feminist scholar Elisabeth Bronfen reinvestigates medical writings and cultural performance to reveal the continued relevance of a disorder widely thought to be a romantic formulation of the past. Through a critical rereading, she develops a new concept of hysteria, one that challenges traditional gender-based theories linking it to dissatisfied feminine sexual desire. Bronfen turns instead to hysteria's traumatic causes, particularly the fear of violation, and shows how the conversion of psychic anguish into somatic symptoms can be interpreted today as the enactment of personal and cultural discontent. Tracing the development of cultural formations of hysteria from the 1800s to the present, this book explores the writings of Freud, Charcot, and Janet together with fictional texts (Radcliffe, Stoker, Anne Sexton), opera (Mozart, Wagner), cinema (Cronenberg, Hitchcock, Woody Allen), and visual art (Marie-Ange Guilleminot, Cindy Sherman). Each of these creative works attests to a particular relationship between hysteria and self-fashioning, and enables us to read hysteria quite literally as a language of discontent. The message broadcasted by the hysteric is one of vulnerability: vulnerability of the symbolic, of identity, and of the human body itself. Throughout this work, Bronfen not only offers fresh approaches to understanding hysteria in our culture, but also introduces a new metaphor to serve as a theoretical tool. Whereas the phallus has long dominated psychoanalytical discourse, the image of the navel--a knotted originary wound common to both genders--facilitates discussion of topics relevant to hysteria, such as trauma, mortality, and infinity. Bronfen's insights make for a lively, innovative work sure to interest readers across the fields of art and literature, feminism, and psychology. Originally published in 1998.

There have been many books, movies, and even TV commercials featuring Neandertals-some serious, some comical. But what was it really like to be a Neandertal? How were their lives similar to or different from ours? In How to Think Like a Neandertal, archaeologist Thomas Wynn and psychologist Frederick L. Coolidge team up to provide a brilliant account of the mental life of Neandertals, drawing on the most recent fossil and archaeological remains. Indeed, some Neandertal remains are not fossilized, allowing scientists to recover samples of their genes-one specimen had the gene for red hair and, more provocatively, all had a gene called FOXP2, which is thought to be related to speech. Given the differences between their faces and ours, their voices probably sounded a bit different, and the range of consonants and vowels they could generate might have been different. But they could talk, and they had a large (perhaps huge) vocabulary-words for places, routes, techniques, individuals, and emotions. Extensive archaeological remains of stone tools and living sites (and, yes, they did often live in caves) indicate that Neandertals relied on complex technical procedures and spent most of their lives in small family groups. The authors sift the evidence that Neandertals had a symbolic culture-looking at their treatment of corpses, the use of fire, and possible body coloring-and conclude that they probably did not have a sense of the supernatural. The book explores the brutal nature of their lives, especially in northwestern Europe, where men and women with spears hunted together for mammoths and wooly rhinoceroses. They were pain tolerant, very likely taciturn, and not easy to excite. Wynn and Coolidge offer here an eye-opening portrait of Neandertals, painting a remarkable picture of these long-vanished people and providing insight, as they go along, into our own minds and culture.

Evolutionary medicine has been steadily gaining recognition, not only in modern clinical research and practice, but also in bioarchaeology (the study of archaeological human remains) and especially its sub-discipline, palaeopathology. To date, however, palaeopathology has not been necessarily recognised as particularly useful to the field and most key texts in evolutionary medicine have tended to overlook it. This novel text is the first to highlight the benefits of using palaeopathological research to answer questions about the evolution of disease and its application to current health problems, as well as the benefits of using evolutionary thinking in medicine to help interpret historical disease processes. It presents hypothesis-driven research by experts in biological anthropology (including palaeopathology), medicine, health sciences, and evolutionary medicine through a series of unique case studies that address specific research questions. Each chapter has been co-authored by two or more researchers with different disciplinary perspectives in order to provide original, insightful, and interdisciplinary contributions that will provide new insights for both palaeopathology and evolutionary medicine. Palaeopathology and Evolutionary Medicine is intended for graduate level students and professional researchers in a wide range of fields including the humanities (history), social sciences (anthropology, archaeology, palaeopathology, geography), and life sciences (medicine and biology). Relevant courses include evolutionary medicine, evolutionary anthropology, medical anthropology, and palaeopathology.

The Syrian crisis is one of the most serious humanitarian disasters in recent history. Yet the widely reported numbers-more than 6 million displaced, including 5 million refugees-reflect only a fractional toll of the conflict. Numerous international organizations, states, and civil society movements have called for the laws of war to be respected, sieges lifted, and humanitarian access facilitated. But beneath each of these humanitarian appeals lies a complicated reality extending beyond the binary narratives that have come to define the war in Syria. Everybody's War examines the complexities of humanitarianism in Syria and the wide-ranging consequences for both Syria's populations and humanitarian responses to future conflicts. Organized by Medecins Sans Frontieres, this edited volume brings together academics and humanitarian practitioners from across the globe to provide a multitude of perspectives on the politics of aid in the Syrian war. Contributors explore the humanitarian crisis behind the Syrian conflict through the history and fragmentation of Syrian health care, the role of international humanitarian law in enabling attacks on health facilities, and the lived experience of siege in all its layers. Further attention is given to the ways in which humanitarian actors have fed the war economy and joined the information wars that have raged throughout the region over the past ten years. While the Syrian crisis has been everybody's war, it has certainly not been everybody's victory. This volume shares the intricate story of aid delivery and humanitarian complicity within one of the defining conflicts of the twenty-first century.

Since the 1970s, understanding of the effects of trauma, including flashbacks and withdrawal, has become widespread in the United States. As a result Americans can now claim that the phrase posttraumatic stress disorder (PTSD) is familiar even if the American Psychiatric Association's criteria for diagnosis are not. As embedded as these ideas now are in the American mindset, however, they are more widely applicable, this volume attempts to show, than is generally recognized. The essays in Culture and PTSD trace how trauma and its effects vary across historical and cultural contexts. Culture and PTSD examines the applicability of PTSD to other cultural contexts and details local responses to trauma and the extent they vary from PTSD as defined in the American Psychiatric Association's Diagnostic and Statistical Manual. Investigating responses in Peru, Indonesia, Haiti, and Native American communities as well as among combat veterans, domestic abuse victims, and adolescents, contributors attempt to address whether PTSD symptoms are present and, if so, whether they are a salient part of local responses to trauma. Moreover, the authors explore other important aspects of the local presentation and experience of trauma-related disorder, whether the Western concept of PTSD is known to lay members of society, and how the introduction of PTSD shapes local understandings and the course of trauma-related disorders. By attempting to determine whether treatments developed for those suffering PTSD in American and European contexts are effective in global settings of violence or disaster, Culture and PTSD questions the efficacy of international responses that focus on trauma.
