As recent stories in the news have shown, maintaining the integrity of the food supply is of critical importance to the consumer. Thousands of Americans die each year from food-borne illnesses, and millions more get sick. Tremendous strides have been made to reduce the incidence of food-borne diseases originating from animal-derived foods, but food safety and food-borne pathogens continue to remain problematic throughout the world. Food-safety scientists from around the nation continue to conduct groundbreaking research not only to understand causative factors in food-borne pathogen prevalence but to develop novel intervention strategies for limiting contamination in all phases of food animal production. The twenty-four essays in this book highlight research efforts of researchers from the tristate Food Safety Consortium established in 1988 by Congress as a research alliance of food-safety scientists at the University of Arkansas, Iowa State University, and Kansas State University. Members of the consortium conduct research through an annual grant approved by Congress and administered by the U.S. Department of Agriculture. Its mission is to conduct extensive investigation into all areas of poultry, beef, and pork meat production, from the farm to the consumer's table. In addition to the consortium researchers, collaborative university researchers, government officials, and industry personnel provide timely reviews of their latest findings with regard to five significant subject areas: preharvest food-borne pathogen ecology and intervention strategies, postharvest food-borne pathogen ecology, rapid methods and detection strategies for food-borne pathogens, antibiotics and antimicrobials in food safety, and emerging issues in food safety. Progress in these research areas provides opportunities to further enhance protection of animal-derived foods from farm to fork.

Seven decades after his death, German Jewish writer, philosopher, and literary critic Walter Benjamin (1892-1940) continues to fascinate and influence. Here Uwe Steiner offers a comprehensive and sophisticated introduction to the oeuvre of this intriguing theorist.Acknowledged only by a small circle of intellectuals during his lifetime, Benjamin is now a major figure whose work is essential to an understanding of modernity. Steiner traces the development of Benjamin's thought chronologically through his writings on philosophy, literature, history, politics, the media, art, photography, cinema, technology, and theology. Walter Benjamin reveals the essential coherence of its subject's thinking while also analyzing the controversial or puzzling facets of Benjamin's work. That coherence, Steiner contends, can best be appreciated by placing Benjamin in his proper context as a member of the German philosophical tradition and a participant in contemporary intellectual debates.As Benjamin's writing attracts more and more readers in the English-speaking world, Walter Benjamin will be a valuable guide to this fascinating body of work.

Over the past half-century, bookselling, like many retail industries, has evolved from an arena dominated by independent bookstores to one in which chain stores have significant market share. And as in other areas of retail, this transformation has often been a less-than-smooth process. This has been especially pronounced in bookselling, argues Laura J. Miller, because more than most other consumer goods, books are the focus of passionate debate. What drives that debateAnd why do so many people believe that bookselling should be immune to questions of profit?In Reluctant Capitalists, Miller looks at a century of book retailing, demonstrating that the independent/chain dynamic is not entirely new. It began one hundred years ago when department stores began selling books, continued through the 1960s with the emergence of national chain stores, and exploded with the formation of "e;superstores"e; in the 1990s. The advent of the Internet has further spurred tremendous changes in how booksellers approach their business. All of these changes have met resistance from book professionals and readers who believe that the book business should somehow be "e;above"e; market forces and instead embrace more noble priorities.Miller uses interviews with bookstore customers and members of the book industry to explain why books evoke such distinct and heated reactions. She reveals why customers have such fierce loyalty to certain bookstores and why they identify so strongly with different types of books. In the process, she also teases out the meanings of retailing and consumption in American culture at large, underscoring her point that any type of consumer behavior is inevitably political, with consequences for communities as well as commercial institutions.

Not Without Honor threads together the stories of three American POWs-Carano; his buddy Bill Blackmon, who was also at Stalag 17 b; and John C. Bitzer, who survived the brutal "e;Death March"e; from northern Germany to liberation in April 1945. At times the journal reads like a thriller as he records air battles and escape attempts. Yet in their most gripping accounts, these POWs ruminate on psychological survival. The sense of community they formed was instrumental to their endurance. This compelling book allows the reader to journey with these young men as they bore firsthand witness to the best and worst of human nature.

With the arrival of the transcontinental railroad in the 1880s came the emergence of a modern and profoundly multicultural New Mexico. Native Americans, working-class Mexicans, elite Hispanos, and black and white newcomers all commingled and interacted in the territory in ways that had not been previously possible. But what did it mean to be white in this multiethnic milieuAnd how did ideas of sexuality and racial supremacy shape ideas of citizenry and determine who would govern the region?Coyote Nation considers these questions as it explores how New Mexicans evaluated and categorized racial identities through bodily practices. Where ethnic groups were numerous and-in the wake of miscegenation-often difficult to discern, the ways one dressed, bathed, spoke, gestured, or even stood were largely instrumental in conveying one's race. Even such practices as cutting one's hair, shopping, drinking alcohol, or embalming a deceased loved one could inextricably link a person to a very specific racial identity.A fascinating history of an extraordinarily plural and polyglot region, Coyote Nation will be of value to historians of race and ethnicity in American culture.

Affect, or the process by which emotions come to be embodied, is a burgeoning area of interest in both the humanities and the sciences. For Timing of Affect, Marie-Luise Angerer, Bernd Bosel, and Michaela Ott have assembled leading scholars to explore the temporal aspects of affect through the perspectives of philosophy, music, film, media, and art, as well as technology and neurology. The contributions address possibilities for affect as a capacity of the body; as an anthropological in*ion and a primary, ontological conjunctive and disjunctive processes; as an interruption of chains of stimulus and response; and as an arena within cultural history for political, media, and psychopharmacological interventions. Showing how these and other temporal aspects of affect are articulated both throughout history and in contemporary society, the editors then explore the implications for the current knowledge structures surrounding affect today.

The Spirit of the Laws-Montesquieu's huge, complex, and enormously influential work-is considered one of the central texts of the Enlightenment, laying the foundation for the liberally democratic political regimes that were to embody its values. In his penetrating analysis, Thomas L. Pangle brilliantly argues that the inherently theological project of Enlightenment liberalism is made more clearly-and more consequentially- in Spirit than in any other work.In a probing and careful reading, Pangle shows how Montesquieu believed that rationalism, through the influence of liberal institutions and the spread of commercial culture, would secularize human affairs. At the same time, Pangle uncovers Montesquieu's views about the origins of humanity's religious impulse and his confidence that political and economic security would make people less likely to sacrifice worldly well-being for otherworldly hopes. With the interest in the theological aspects of political theory and practice showing no signs of diminishing, this book is a timely and insightful contribution to one of the key achievements of Enlightenment thought.

Ancient Greek tragedy has been an inspiration to Western culture, but the way it was first performed has long remained in question. In The Theatricality of Greek Tragedy, Graham Ley provides an illuminating discussion of key issues relating to the use of the playing space and the nature of the chorus, offering a distinctive impression of the performance of Greek tragedy in the fifth century BCE. Drawing on evidence from the surviving texts of tragedies by Aeschylus, Sophocles, and Euripides, Ley explains how scenes with actors were played in the open ground of the orchestra, often considered as exclusively the dancing place of the chorus. In reviewing what is known of the music and dance of Greek antiquity, Ley goes on to show that in the original productions the experience of the chorus-expressed in song and dance and in interaction with the characters-remained a vital characteristic in the performance of tragedy.Combining detailed analysis with broader reflections about the nature of ancient Greek tragedy as an art form, this volume-supplemented with a series of illustrative drawings and diagrams-will be a necessary addition to the bookshelf of anyone interested in literature, theater, or classical studies.

Just as a single pot starts with a lump of clay, the study of a piece's history must start with an understanding of its raw materials. This principle is the foundation of Pottery Analysis, the acclaimed sourcebook that has become the indispensable guide for archaeologists and anthropologists worldwide. By grounding current research in the larger history of pottery and drawing together diverse approaches to the study of pottery, it offers a rich, comprehensive view of ceramic inquiry.This new edition fully incorporates more than two decades of growth and diversification in the fields of archaeological and ethnographic study of pottery. It begins with a summary of the origins and history of pottery in different parts of the world, then examines the raw materials of pottery and their physical and chemical properties. It addresses ethnographic and ethnoarchaeological perspectives on pottery production; reviews the methods of studying pottery's physical, mechanical, thermal, mineralogical, and chemical properties; and discusses how proper analysis of artifacts can reveal insights into their culture of origin. Intended for use in the classroom, the lab, and out in the field, this essential text offers an unparalleled basis for pottery research.

Along with reproduction, balancing energy expenditure with the limits of resource acquisition is essential for both a species and a population to survive. But energy is a limited resource, as we know well, so birds and mammals-the most energy-intensive fauna on the planet-must reduce energy expenditures to maintain this balance, some taking small steps, and others extreme measures.Here Brian K. McNab draws on his over sixty years in the field to provide a comprehensive account of the energetics of birds and mammals, one fully integrated with their natural history. McNab begins with an overview of thermal rates-much of our own energy is spent maintaining our 98.6?F temperature-and explains how the basal rate of metabolism drives energy use, especially in extreme environments. He then explores those variables that interact with the basal rate of metabolism, like body size and scale and environments, highlighting their influence on behavior, distribution, and even reproductive output. Successive chapters take up energy and population dynamics and evolution. A critical central theme that runs through the book is how the energetic needs of birds and mammals come up against rapid environmental change and how this is hastening the pace of extinction.

For far too long humans have been ignoring nature. As the most dominant, overproducing, overconsuming, big-brained, big-footed, arrogant, and invasive species ever known, we are wrecking the planet at an unprecedented rate. And while science is important to our understanding of the impact we have on our environment, it alone does not hold the answers to the current crisis, nor does it get people to act. In Ignoring Nature No More, Marc Bekoff and a host of renowned contributors argue that we need a new mind-set about nature, one that centers on empathy, compassion, and being proactive.?This collection of diverse essays is the first book devoted to compassionate conservation, a growing global movement that translates discussions and concerns about the well-being of individuals, species, populations, and ecosystems into action. Written by leading scholars in a host of disciplines, including biology, psychology, sociology, social work, economics, political science, and philosophy, as well as by locals doing fieldwork in their own countries, the essays combine the most creative aspects of the current science of animal conservation with analyses of important psychological and sociocultural issues that encourage or vex stewardship. The contributors tackle topics including the costs and benefits of conservation, behavioral biology, media coverage of animal welfare, conservation psychology, and scales of conservation from the local to the global. Taken together, the essays make a strong case for why we must replace our habits of domination and exploitation with compassionate conservation if we are to make the world a better place for nonhuman and human animals alike.

Galileo's telescopic discoveries, and especially his observation of sunspots, caused great debate in an age when the heavens were thought to be perfect and unchanging. Christoph Scheiner, a Jesuit mathematician, argued that sunspots were planets or moons crossing in front of the Sun. Galileo, on the other hand, countered that the spots were on or near the surface of the Sun itself, and he supported his position with a series of meticulous observations and mathematical demonstrations that eventually convinced even his rival.?On Sunspots collects the correspondence that constituted the public debate, including the first English translation of Scheiner's two tracts as well as Galileo's three letters, which have previously appeared only in abridged form. In addition, Albert Van Helden and Eileen Reeves have supplemented the correspondence with lengthy introductions, extensive notes, and a bibliography. The result will become the standard work on the subject, essential for students and historians of astronomy, the telescope, and early modern Catholicism.

Although the subject of federally mandated Institutional Review Boards (IRBs) has been extensively debated, we actually do not know much about what takes place when they convene. The story of how IRBs work today is a story about their past as well as their present, and Behind Closed Doors is the first book to meld firsthand observations of IRB meetings with the history of how rules for the treatment of human subjects were formalized in the United States in the decades after World War II.?Drawing on extensive archival sources, Laura Stark reconstructs the daily lives of scientists, lawyers, administrators, and research subjects working-and "e;warring"e;-on the campus of the National Institutes of Health, where they first wrote the rules for the treatment of human subjects. Stark argues that the model of group deliberation that gradually crystallized during this period reflected contemporary legal and medical conceptions of what it meant to be human, what political rights human subjects deserved, and which stakeholders were best suited to decide. She then explains how the historical contingencies that shaped rules for the treatment of human subjects in the postwar era guide decision making today-within hospitals, universities, health departments, and other institutions in the United States and across the globe. Meticulously researched and gracefully argued, Behind Closed Doors will be essential reading for sociologists and historians of science and medicine, as well as policy makers and IRB administrators.

These days, the idea of the cyborg is less the stuff of science fiction and more a reality, as we are all, in one way or another, constantly connected, extended, wired, and dispersed in and through technology. One wonders where the individual, the person, the human, and the body are-or, alternatively, where they stop. These are the kinds of questions Hlne Mialet explores in this fascinating volume, as she focuses on a man who is permanently attached to assemblages of machines, devices, and collectivities of people: Stephen Hawking.Drawing on an extensive and in-depth series of interviews with Hawking, his assistants and colleagues, physicists, engineers, writers, journalists, archivists, and artists, Mialet reconstructs the human, material, and machine-based networks that enable Hawking to live and work. She reveals how Hawking-who is often portrayed as the most singular, individual, rational, and bodiless of all-is in fact not only incorporated, materialized, and distributed in a complex nexus of machines and human beings like everyone else, but even more so. Each chapter focuses on a de*ion of the functioning and coordination of different elements or media that create his presence, agency, identity, and competencies. Attentive to Hawking's daily activities, including his lecturing and scientific writing, Mialet's ethnographic analysis powerfully reassesses the notion of scientific genius and its associations with human singularity. This book will fascinate anyone interested in Stephen Hawking or an extraordinary life in science.

Exploring Peru's lively music industry and the studio producers, radio DJs, and program directors that drive it, Gentleman Troubadours and Andean Pop Stars is a fascinating account of the deliberate development of artistic taste. Focusing on popular huayno music and the ways it has been promoted to Peru's emerging middle class, Tucker tells a complex story of identity making and the marketing forces entangled with it, providing crucial insights into the dynamics among art, class, and ethnicity that reach far beyond the Andes.?Tucker focuses on the music of Ayacucho, Peru, examining how media workers and intellectuals there transformed the city's huayno music into the country's most popular style. By marketing contemporary huayno against its traditional counterpart, these agents, Tucker argues, have paradoxically reinforced ethnic hierarchies at the same time that they have challenged them. Navigating between a burgeoning Andean bourgeoisie and a music industry eager to sell them symbols of newfound sophistication, Gentleman Troubadours and Andean Pop Stars is a deep account of the real people behind cultural change.

Why do we need new artHow free is the artist in makingAnd why is the artist, and particularly the poet, a figure of freedom in Western cultureThe MacArthur Award-winning poet and critic Susan Stewart ponders these questions in The Poet's Freedom. Through a series of evocative essays, she not only argues that freedom is necessary to making and is itself something made, but also shows how artists give rules to their practices and model a self-determination that might serve in other spheres of work.Stewart traces the ideas of freedom and making through insightful readings of an array of Western philosophers and poets-Plato, Homer, Marx, Heidegger, Arendt, Dante, and Coleridge are among her key sources. She begins by considering the theme of making in the Hebrew Scriptures, examining their accountof a god who creates the world and leaves humans free to rearrange and reform the materials of nature. She goes on to follow the force of moods, sounds, rhythms, images, metrical rules, rhetorical traditions, the traps of the passions, and the nature of language in the cycle of making and remaking. Throughout the book she weaves the insight that the freedom to reverse any act of artistic making is as essential as the freedom to create.?A book about the pleasures of making and thinking as means of life, The Poet's Freedom explores and celebrates the freedom of artists who, working under finite conditions, make considered choices and shape surprising consequences. This engaging and beautifully written notebook on making will attract anyone interested in the creation of art and literature.

Shakespeare wrote of lions, shrews, horned toads, curs, mastiffs, and hellhounds. But the word "e;animal"e; itself only appears very rarely in his work, which was in keeping with sixteenth-century usage. As Laurie Shannon reveals in The Accommodated Animal, the modern human / animal divide first came strongly into play in the seventeenth century, with Descartes's famous formulation that reason sets humans above other species: "e;I think, therefore I am."e; Before that moment, animals could claim a firmer place alongside humans in a larger vision of belonging, or what she terms cosmopolity.?With Shakespeare as her touchstone, Shannon explores the creaturely dispensation that existed until Descartes. She finds that early modern writers used classical natural history and readings of Genesis to credit animals with various kinds of stakeholdership, prerogative, and entitlement, employing the language of politics in a constitutional vision of cosmic membership. Using this political idiom to frame cross-species relations, Shannon argues, carried with it the notion that animals possess their own investments in the world, a point distinct from the question of whether animals have reason. It also enabled a sharp critique of the tyranny of humankind. By answering "e;the question of the animal"e; historically, The Accommodated Animal makes a brilliant contribution to cross-disciplinary debates engaging animal studies, political theory, intellectual history, and literary studies.
