Every minute a Nigerian man, woman, or child becomes infected with HIV. Soon Nigeria will be home to more people living with HIV than any other country in Africa. With 5 percent of its inhabitants already infected, Nigeria has reached the critical threshold that can catapult rates to nearly 40 percent of a country's population. The full magnitude of Nigeria's epidemic will be determined by its response now.

AIDS in Nigeria helps guide that response. Written by dozens of the country's leading HIV experts, the book explores the dynamics of the epidemic, analyzes prevention efforts, identifies crucial gaps, and formulates effective strategies for controlling the epidemic. Complementing the experts' words are the dramatic portraits of people whose lives have been forever transformed by AIDS. Their stories reveal the human costs of the epidemic--and the courage required to overcome it.

Adolescents embody the best hopes of American society. Their vital role in shaping our future lends particular significance to their success in negotiating the passage from childhood to adulthood, while their intensity and visibility often make them barometers of social change. It is all the more remarkable, then, that this critical period has only recently captured the full attention of researchers.

At the Threshold presents the long-awaited findings of the Carnegie Foundation study on adolescence. It offers a comprehensive overview of what investigators are learning about normal development and provides an interdisciplinary synthesis of research into the biological, social, and psychological changes occurring during this key stage in the life span. While focusing on the contexts of adolescent life—social and ethnic, family and school, leisure and work—it also addresses how researchers are doing in the effort to understand the intersection of processes that initiate and sustain adolescent development and to characterize the extraordinary changes that occur during these years.

Contrary to popular belief, large numbers of young people continue to mature into productive members of society. At the Threshold seeks to allow professionals and nonprofessionals alike important access to the reality of normal adolescent experience. The authors recognize that only if we begin to understand and clearly articulate the parameters of successful adolescent development can we hope to intervene with those individuals whose lives seem aimed toward unsatisfactory futures.

What happens when historiography—the way historical events are committed to writing—shapes historical events as they occur? How do we read biography when it is truly “life-writing,” its subjects fully engaged with the historiographical rhetoric that would record their words and deeds?

The Threshold, a study of the culture of historiography in early medieval China, explores these questions through the lens of the History of Liu-Song, a dynastic history compiled in 488 and covering the first three-quarters of the fifth century. Rhetoric courses through early medieval historiography: from the way a historian framed history for readers to the political machinations contained within historical narratives, from the active use of rhetorical techniques to the passive effect that embedded discourses exercised on historian, historical actor, and reader alike. Tracing these varied strands of historical argumentation, Zeb Raft shows how history was constructed through rhetorical elements including the narration of officialdom, the anecdote, and, above all, the historical document. The portrait that emerges is of an epideictic historiography where praise was mixed with irony and achievement diluted with ambivalence—and where the most secure positions lay on the threshold of political power and historical interpretation.
