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.

In 1997, after General Motors shuttered a massive complex of factories in the gritty industrial city of Flint, Michigan, signs were placed around the empty facility reading, "e;Demolition Means Progress,"e; suggesting that the struggling metropolis could not move forward to greatness until the old plants met the wrecking ball. Much more than a trite corporate slogan, the phrase encapsulates the operating ethos of the nation's metropolitan leadership from at least the 1930s to the present. Throughout, the leaders of Flint and other municipalities repeatedly tried to revitalize their communities by demolishing outdated and inefficient structures and institutions and overseeing numerous urban renewal campaigns-many of which yielded only more impoverished and more divided metropolises. After decades of these efforts, the dawn of the twenty-first century found Flint one of the most racially segregated and economically polarized metropolitan areas in the nation.In one of the most comprehensive works yet written on the history of inequality and metropolitan development in modern America, Andrew R. Highsmith uses the case of Flint to explain how the perennial quest for urban renewal-even more than white flight, corporate abandonment, and other forces-contributed to mass suburbanization, racial and economic division, deindustrialization, and political fragmentation. Challenging much of the conventional wisdom about structural inequality and the roots of the nation's "e;urban crisis,"e; Demolition Means Progress shows in vivid detail how public policies and programs designed to revitalize the Flint area ultimately led to the hardening of social divisions.

The dark shadows and offscreen space that force us to imagine violence we cannot see. The real slaughter of animals spliced with the fictional killing of men. The missing countershot from the murder victim's point of view. Such images, or absent images, Karla Oeler contends, distill how the murder scene challenges and changes film.?Reexamining works by such filmmakers as Renoir, Hitchcock, Kubrick, Jarmusch, and Eisenstein, Oeler traces the murder scene's intricate connections to the great breakthroughs in the theory and practice of montage and the formulation of the rules and syntax of Hollywood genre. She argues that murder plays such a central role in film because it mirrors, on multiple levels, the act of cinematic representation. Death and murder at once eradicate life and call attention to its former existence, just as cinema conveys both the reality and the absence of the objects it depicts. But murder shares with cinema not only this interplay between presence and absence, movement and stillness: unlike death, killing entails the deliberate reduction of a singular subject to a disposable object. Like cinema, it involves a crucial choice about what to cut and what to keep.

Girls abused in London and torsos of black boys found in the Thames; African boys disappearing from school and child traffic in Africa; child sacrifice and Brazilian Pentecostal exorcism. Unrelated events are swiftly connected in an uncanny work of prestidigitation, including hitech digital images of torsos and forensic drawings of abused children. Les correspondances symboliques, Baudelaire would say, or contiguous magic, in Frazer’s more prosaic de*ion. It all could make sense, if we believe in our fears, suspicions, gossip, and prejudices. Furthermore, this incredible work of prestidigitation was engineered by two respectable institutions, known for their enlightened search of truth: the BBC and Scotland Yard. But where was the evidence that all these things were connectedThe “exorcism scandal” bewitched the media in Britain for the whole month of June, until some dissenting voices started to talk about a “racist witch hunt.” 5 By then, however, a population of hundreds of thousands of Africans, in particular Pentecostal Africans, was already under suspicion. “What if some of that was true?” some people still may ask. In fact, shortly before completing this introduction, the local London newspaper Evening Standard published a two-page report on an African church in the United Kingdom, with the title “Miracles and claims of baby-snatching,” mixing rumors of child trafficking, sorcery, syncretism, and extreme wealth. 6 That is how sorcery works: not by fully demonstrating its power, but by opening a possible doubt; one is never fully sure it is not true.

As our world becomes increasingly urbanized, an understanding of the context, mechanisms, and consequences of city and suburban environments becomes more critical. Without a sense of what open spaces such as parks and gardens contribute, it's difficult to argue for their creation and maintenance: in the face of schools needing resources, roads and sewers needing maintenance, and people suffering at the hands of others, why should cities and counties spend scarce dollars planting trees and preserving parksIn Constructed Climates, ecologist William G. Wilson demonstrates the value of urban green. Focusing specifically on the role of vegetation and trees, Wilson shows the costs and benefits reaped from urban open spaces, from cooler temperatures to better quality ground water-and why it all matters. While Constructed Climates is a work of science, it does not ignore the social component. Wilson looks at low-income areas that have poor vegetation, and shows how enhancing these areas through the planting of community gardens and trees can alleviate social ills. This book will be essential reading for environmentalists and anyone making decisions for the nature and well-being of our cities and citizens.

What did it mean to be a man in medieval EnglandMost would answer this question by alluding to the power and status men enjoyed in a patriarchal society, or they might refer to iconic images of chivalrous knights. While these popular ideas do have their roots in the history of the aristocracy, the experience of ordinary men was far more complicated. Marshalling a wide array of colorful evidence-including legal records, letters, medical sources, and the literature of the period-Derek G. Neal here plumbs the social and cultural significance of masculinity during the generations born between the Black Death and the Protestant Reformation. He discovers that social relations between men, founded on the ideals of honesty and self-restraint, were at least as important as their domination and control of women in defining their identities. By carefully exploring the social, physical, and psychological aspects of masculinity, The Masculine Self in Late Medieval England offers a uniquely comprehensive account of the exterior and interior lives of medieval men.

Sound-one of the central elements of poetry-finds itself all but ignored in the current discourse on lyric forms. The essays collected here by Marjorie Perloff and Craig Dworkinbreak that critical silence to readdress some of thefundamental connections between poetry and sound-connections that go far beyond traditional metrical studies.Ranging from medieval Latin lyrics to a cyborg opera, sixteenth-century France to twentieth-century Brazil, romantic ballads to the contemporary avant-garde, the contributors to The Sound of Poetry/The Poetry of Sound explore such subjects as the translatability of lyric sound, the historical and cultural roles of rhyme,the role of sound repetition in novelistic prose, theconnections between "e;sound poetry"e; and music, between the visual and the auditory, the role of the body in performance, and the impact of recording technologies on the lyric voice. Along the way, the essaystake on the "e;ensemble discords"e; of Maurice Scve's Dlie, Ezra Pound's use of "e;Chinese whispers,"e; the alchemical theology of Hugo Ball's Dada performances, Jean Cocteau's modernist radiophonics, and an intercultural account of the poetry reading as a kind of dubbing.A genuinely comparatist study, The Sound of Poetry/The Poetry of Sound is designed to challenge current preconceptions about what Susan Howe has called "e;articulations of sound forms in time"e; as they have transformed the expanded poetic field of the twenty-first century.

In April 2003, the world watched in horror as part of Iraq's cultural heritage disintegrated among the rubble of Saddam Hussein's regime. Looters descended on the Iraq National Museum in Baghdad, Arabic manu*s disappeared from the National Library, and countless Iraqi government records were destroyed. For those to whom Iraq meant only terror, weapons of mass destruction, or oil, several thousand years of history between the Tigris and the Euphrates opened into view. Basic techniques and concepts of civilization, without which human society would not have attained its present level, had their origin there. A writing system, the prerequisite of modern and premodern societies, was part of the human knowledge that spread from Mesopotamia, as were bureaucratic techniques such as archiving, still basic to any modern administration, or early forms of monotheism. Such “firsts” will be highlighted in the following pages. But the uniqueness of the ancient Mesopotamian culture rests not only on countless innovations of this kind but, to an even greater degree, on the fact that we can follow its gradual development and its absorption into the cultural canon over a period of ten thousand years, almost without major gaps.

Imbued with character and independence, strength and articulateness, humor and conviction, abundant biblical knowledge and intense compassion, Katharina Schutz Zell (1498-1562) was an outspoken religious reformer in sixteenth-century Germany who campaigned for the right of clergy to marry and the responsibility of lay people-women as well as men-to proclaim the Gospel. As one of the first and most daring models of the pastor's wife in the Protestant Reformation, Schutz Zell demonstrated that she could be an equal partner in marriage; she was for many years a respected, if unofficial, mother of the established church of Strasbourg in an age when ecclesiastical leadership was dominated by men.Though a commoner, Schtz Zell participated actively in public life and wrote prolifically, including letters of consolation, devotional writings, biblical meditations, catechetical instructions, a sermon, and lengthy polemical exchanges with male theologians. The complete translations of her extant publications, except for her longest, are collected here in Church Mother, offering modern readers a rare opportunity to understand the important work of women in the formation of the early Protestant church.

So certain is this that we may boldly state that it is absurd for human beings even to attempt it, or to hope that perhaps some day another Newton might arise who would explain to us, in terms of natural laws unordered by intention, how even a mere blade of grass is produced．Kant, Critique of Judgment (1790)
