    By delving into lives that would otherwise go unremarked, Kelly documents the modernization of the sex industry during the neoliberal era in the city of Tuxtla Gutiérrez and illustrates how state-regulated sex became part of a broader effort by government officials to bring modernity to Chiapas, one of Mexico's poorest and most conflicted states. Kelly's innovative approach locates prostitution in a political-economic context by treating it as work. Most valuably, she conveys her analysis through vivid portraits of the lives of the sex workers themselves and shows how the women involved are neither victims nor heroines.

    Laura M. Ahearn shows that young Nepalese people are applying their newly acquired literacy skills to love-letter writing, fostering a transition that involves not only a shift in marriage rituals, but also a change in how villagers conceive of their own ability to act and attribute responsibility for events. These developments have potential ramifications that extend far beyond the realm of marriage and well past the Himalayas.The love-letter correspondences examined by Ahearn also provide a deeper understanding of the social effects of literacy. While the acquisition of literary skills may open up new opportunities for some individuals, such skills can also impose new constraints, expectations, and disappointments. The increase in female literacy rates in Junigau in the 1990s made possible the emergence of new courtship practices and facilitated self-initiated marriages, but it also reinforced certain gender ideologies and undercut some avenues to social power, especially for women. Scholars, and students in such fields as anthropology, women's studies, linguistics, development studies, and South Asian studies will find this book ethnographically rich and theoretically insightful. Laura M. Ahearn is Assistant Professor of Anthropology, Rutgers University.

    Linda Tirado, in her signature brutally honest yet personable voice, takes all of these preconceived notions and smashes them to bits. She articulates not only what it is to be working poor in America (yes, you can be poor and live in a house and have a job, even two), but what poverty is truly like—on all levels. Frankly and boldly, Tirado discusses openly how she went from lower-middle class, to sometimes middle class, to poor and everything in between, and in doing so reveals why “poor people don’t always behave the way middle-class America thinks they should.”

    She puts the English national character under her anthropological microscope, and finds a strange and fascinating culture, governed by complex sets of unspoken rules and byzantine codes of behaviour. The rules of weather-speak. The ironic-gnome rule. The reflex apology rule. The paranoid-pantomime rule. Class indicators and class anxiety tests. The money-talk taboo and many more ...Through a mixture of anthropological analysis and her own unorthodox experiments (using herself as a reluctant guinea-pig), Kate Fox discovers what these unwritten behaviour codes tell us about Englishness.

    News of both the Ice Man's discovery and his age, which was put at over five thousand years, fascinated scientists and newspapers throughout the world. But what made Sykes's story particularly revelatory was his successful identification of a genetic descendant of the Ice Man, a woman living in Great Britain today. How was Sykes able to locate a living relative of a man who died thousands of years ago?In The Seven Daughters of Eve, he gives us a firsthand account of his research into a remarkable gene, which passes undiluted from generation to generation through the maternal line. After plotting thousands of DNA sequences from all over the world, Sykes found that they clustered around a handful of distinct groups. Among Europeans and North American Caucasians, there are, in fact, only seven. This conclusion was staggering: almost everyone of native European descent, wherever they may live throughout the world, can trace their ancestry back to one of seven women, the Seven Daughters of Eve.Naming them Ursula, Xenia, Helena, Velda, Tara, Katrine, and Jasmine, Sykes has created portraits of their disparate worlds by mapping the migratory patterns followed by millions of their ancestors. In reading the stories of these seven women, we learn exactly how our origins can be traced, how and where our ancient genetic ancestors lived, and how we are each living proof of the almost indestructible strands of DNA, which have survived over so many thousands of years. Indeed, The Seven Daughters of Eve is filled with dramatic stories: from Sykes's identification, using DNA samples from two living relatives, of the remains of Tsar Nicholas and Tsaress Alexandra, to the Caribbean woman whose family had been sold into slavery centuries before and whose ancestry Sykes was able to trace back to the Eastern coast of central Africa. Ultimately, Sykes's investigation reveals that, as a race, what humans have in common is more deeply embedded than what separates us.

    By examining fossils and DNA, Shubin shows us that our hands actually resemble fish fins, our head is organized like that of a long-extinct jawless fish, and major parts of our genome look and function like those of worms and bacteria.Shubin makes us see ourselves and our world in a completely new light. Your Inner Fish is science writing at its finest-enlightening, accessible, and told with irresistible enthusiasm.

    Today, buffeted by one food fad after another, America is suffering from what can only be described as a national eating disorder. The omnivore's dilemma has returned with a vengeance, as the cornucopia of the modern American supermarket and fast-food outlet confronts us with a bewildering and treacherous food landscape. What's at stake in our eating choices is not only our own and our children's health, but the health of the environment that sustains life on earth.The Omnivore's Dilemma is a groundbreaking book in which one of America's most fascinating, original, and elegant writers turns his own omnivorous mind to the seemingly straightforward question of what we should have for dinner. The question has confronted us since man discovered fire, but, according to Michael Pollan, the bestselling author of The Botany of Desire, how we answer it today, ath the dawn of the twenty-first century, may well determine our very survival as a species. Should we eat a fast-food hamburger? Something organic? Or perhaps something we hunt, gather or grow ourselves?To find out, Pollan follows each of the food chains that sustain us—industrial food, organic or alternative food, and food we forage ourselves—from the source to a final meal, and in the process develops a definitive account of the American way of eating. His absorbing narrative takes us from Iowa cornfields to food laboratories, from feedlots and fast-food restaurants to organic farms and hunting grounds, always emphasizing our dynamic coevolutionary relationship with the handful of plant and animal species we depend on. Each time Pollan sits down to a meal, he deploys his unique blend of personal and investigative journalism to trace the origins of everything consumed, revealing what we unwittingly ingest and explaining how our taste for particular foods and flavors reflects our evolutionary inheritance.The surprising answers Pollan offers to the simple question posed by this book have profound political, economic, psychological, and even mortal implications for all of us. Ultimately, this is a book as much about visionary solutions as it is about problems, and Pollan contends that, when it comes to food, doing the right thing often turns out to be the tastiest thing an eater can do. Beautifully written and thrillingly argued, The Omnivore's Dilemma promises to change the way we think about the politics and pleasure of eating. For anyone who reads it, dinner will never again look, or taste, quite the same.

    Scientists around the world are currently monitoring the sixth extinction, predicted to be the most devastating extinction event since the asteroid impact that wiped out the dinosaurs. This time around, the cataclysm is us. In prose that is at once frank, entertaining, and deeply informed, The New Yorker writer Elizabeth Kolbert tells us why and how human beings have altered life on the planet in a way no species has before. Interweaving research in half a dozen disciplines, descriptions of the fascinating species that have already been lost, and the history of extinction as a concept, Kolbert provides a moving and comprehensive account of the disappearances occurring before our very eyes. She shows that the sixth extinction is likely to be mankind's most lasting legacy, compelling us to rethink the fundamental question of what it means to be human.

    Annawadi is a makeshift settlement in the shadow of luxury hotels near the Mumbai airport, and as India starts to prosper, Annawadians are electric with hope. Abdul, a reflective and enterprising Muslim teenager, sees "a fortune beyond counting" in the recyclable garbage that richer people throw away. Asha, a woman of formidable wit and deep scars from a childhood in rural poverty, has identified an alternate route to the middle class: political corruption. With a little luck, her sensitive, beautiful daughter - Annawadi's "most-everything girl" - will soon become its first female college graduate. And even the poorest Annawadians, like Kalu, a fifteen-year-old scrap-metal thief, believe themselves inching closer to the good lives and good times they call "the full enjoy." But then Abdul the garbage sorter is falsely accused in a shocking tragedy; terror and a global recession rock the city; and suppressed tensions over religion, caste, sex, power and economic envy turn brutal. As the tenderest individual hopes intersect with the greatest global truths, the true contours of a competitive age are revealed. And so, too, are the imaginations and courage of the people of Annawadi. With intelligence, humor, and deep insight into what connects human beings to one another in an era of tumultuous change, Behind the Beautiful Forevers carries the reader headlong into one of the twenty-first century's hidden worlds, and into the lives of people impossible to forget.

    Modonna Harris and her teenage daughter Brianna in Chicago often have no food but spoiled milk on weekends. After two decades of brilliant research on American poverty, Kathryn Edin noticed something she hadn’t seen since the mid-1990s — households surviving on virtually no income. Edin teamed with Luke Shaefer, an expert on calculating incomes of the poor, to discover that the number of American families living on $2.00 per person, per day, has skyrocketed to 1.5 million American households, including about 3 million children. Where do these families live? How did they get so desperately poor? Edin has procured rich — and truthful — interviews. Through the book’s many compelling profiles, moving and startling answers emerge. The authors illuminate a troubling trend: a low-wage labor market that increasingly fails to deliver a living wage, and a growing but hidden landscape of survival strategies among America’s extreme poor. More than a powerful exposé, $2.00 a Day delivers new evidence and new ideas to our national debate on income inequality.

    one of the most important and readable works on the human past published in recent years."Winner of the Pulitzer Prize and a national bestseller: the global account of the rise of civilization that is also a stunning refutation of ideas of human development based on race.In this "artful, informative, and delightful" (William H. McNeill, New York Review of Books) book, Jared Diamond convincingly argues that geographical and environmental factors shaped the modern world. Societies that had a head start in food production advanced beyond the hunter-gatherer stage, and then developed writing, technology, government, and organized religion—as well as nasty germs and potent weapons of war—and adventured on sea and land to conquer and decimate preliterate cultures. A major advance in our understanding of human societies, Guns, Germs, and Steel chronicles the way that the modern world came to be and stunningly dismantles racially based theories of human history.Winner of the Pulitzer Prize, the Phi Beta Kappa Award in Science, the Rhone-Poulenc Prize, and the Commonwealth Club of California's Gold Medal

    The book showcases the talents of a gifted fieldworker whose theoretically rich work sits on the cutting edge of a growing body of scholarship examining the social worlds of children. School officials, parents, and, most especially, a new generation of teachers will benefit from these lessons on race."-American Journal of Sociology"Instructors may recommend this book to students to whom the topic is surely vital and engrossing and for whom the text will be lively and engaging."-Contemporary Sociology"Lewis moves beyond traditional research methods used to examine achievement gaps and differences in test scores to look closely at the realities of schooling. I highly recommend this work for every person involved in teaching and learning."-Multicultural Review"Through eloquent case studies of three California elementary schools-a white-majority 'good' school, a mostly minority 'tough' school, and an integrated 'alternative' school-[Lewis] demonstrates that schools promote racial inequalities through their daily rituals and practices. Even the notion of a "color-blind" America-an especially popular ideal in the white school-perpetuates racism, Lewis argues, because it denies or dismisses the very real constraints that schools place on minorities. Lewis is nevertheless an optimist, insisting that schools can change ideas of race. . . . Highly recommended. Undergraduate collections and above."-Choice "In this pioneering ethnography in elementary schools, Lewis shows brilliantly how racism is taught and learned in the small places of everyday life."-Joe Feagin, University of Florida and author of Racist America"A wonderful and timely book. Ethnographically rich, theoretically sophisticated, and clearly written, this book addresses the ubiquitous issue of race in all its complexity."-Michèle Foster, author of Black Teachers on Teaching"A compelling ethnography of the racial landscape of contemporary schools."-Barrie Thorne, author of Gender Play: Girls and Boys in SchoolCould your kids be learning a fourth R at school: reading, writing, 'rithmatic, and race?Race in the Schoolyard takes us to a place most of us seldom get to see in action¾ our children's classrooms¾ and reveals the lessons about race that are communicated there. Amanda E. Lewis spent a year observing classes at three elementary schools, two multiracial urban and one white suburban. While race of course is not officially taught like multiplication and punctuation, she finds that it nonetheless insinuates itself into everyday life in schools.Lewis explains how the curriculum, both expressed and hidden, conveys many racial lessons. While teachers and other school community members verbally deny the salience of race, she illustrates how it does influence the way they understand the world, interact with each other, and teach children. This eye-opening text is important reading for educators, parents, and scholars alike.

    Known for their simple clothing, plain lifestyle, and horse-and-buggy mode of transportation, Amish communities continually face outside pressures to modify their cultural patterns, social organization, and religious world view. An intimate portrait of Amish life, The Amish explores not only the emerging diversity and evolving identities within this distinctive American ethnic community, but also its transformation and geographic expansion.Donald B. Kraybill, Karen M. Johnson-Weiner, and Steven M. Nolt spent twenty-five years researching Amish history, religion, and culture. Drawing on archival material, direct observations, and oral history, the authors provide an authoritative and sensitive understanding of Amish society.Amish people do not evangelize, yet their numbers in North America have grown from a small community of some 6,000 people in the early 1900s to a thriving population of more than 275,000 today. The largest populations are found in Ohio, Pennsylvania, and Indiana, with additional communities in twenty-seven other states and Ontario.The authors argue that the intensely private and insular Amish have devised creative ways to negotiate with modernity that have enabled them to thrive in America. The transformation of the Amish in the American imagination from "backward bumpkins" to media icons poses provocative questions. What does the Amish story reveal about the American character, popular culture, and mainstream values? Richly illustrated, The Amish is the definitive portrayal of the Amish in America in the twenty-first century.

    She managed a medical research project, ate dog, became pregnant, and responded to spells placed on her. Thirty years later she returned to Pohnpei to learn what had happened there since her first visit. Were islanders still casual about sex? Were they still obsessed with titles and social rank? Was the island still lush and beautiful? Had the inhabitants remained healthy?" This second edition of Ward's best-selling account is a rare, longitudinal study that tracks people, processes, and a place through decades of change. It is also an intimate record of doing fieldwork that immerses readers in the sights, smells, tastes, sounds, and the sensory richness of Pohnpei. Ward addresses the ageless ethnographic questions about family life, politics, religion, traditional medicine, magic, and death together with contemporary concerns about postcolonial survival, the discontinuities of culture, and adaptation to the demands of a global age. Her discoveries illuminate the evolution of a culture possibly distant from yet important to people living in other parts of the world.
