From Research and Reference Book News. . . 'In the new introduction to the award-winning 1999 edition, a Canadian scholar notes that while research on underemployment has increased since then, preoccupation with statistics still emphasizes limited dimensions of the problem of under-utilization of capabilities. Drawing on survey and case study research in advanced economies, Livingstone (U. of Toronto) analyzes various theories (e.g., human capital) as limited in explaining the education-jobs gap. He does support a general conflict theory identifying the highest underemployment with the least powerful social groups.'

Seasonally dry forests are the most widespread forest type remaining in South and Southeast Asia. For many endangered species, such as tigers, elephants, deer and primates, this unique habitat is central to their survival. These forests are also intimately linked to humans in the region, who have lived in and relied on them for centuries. Despite the importance of seasonally dry forests, little is known of their ecology. The essays in this volume draw the connections between forest communities, endangered species, and agricultural communities in the region. The contributors, many of whom are in-country researchers and managers who have spent years studying this ecosystem, provide an overview of the ecology of seasonally dry forests in Asia, descriptions of forest and agricultural communities within seasonally dry forests, case studies for the species dependent on these ecosystems, such as tigers, elephants, deer, banteng, and gibbons and discuss effective management and conservation of seasonally dry forests.

The average American today consumes some 150 pounds of sugars, plus substantial amounts of artificial sweeteners, each year. How this came to be and how sweeteners have affected key aspects of the American experience is the story of Sweet Stuff. This book is the first detailed history on the subject. The narrative covers the major natural sweeteners, including sugar and molasses from cane, beet sugar, corn syrup, sorghum syrup, honey, and maple, as well as the artificial sweeteners saccharin, cyclamate, aspartame, and sucralose. Sweet Stuff discusses sweeteners in the context of diet, science and technology, business and labor, politics, and popular culture. It looks at the ways that federal and state governments promoted some sweeteners and limited the distribution of others. It examines the times when newer and less costly sweeteners threatened the market dominance of older and more expensive ones. Finally, it explores such complex issues as food purity, food safety, and truth in advertising. Sweet Stuff will appeal to those interested in food culture, American culture, and American history.

Capital Portraits: Treasures from Washington Private Collections presents little-known artistic treasures from important Washington area private collections. These portraits by major artists date from the mid-eighteenth century to the present, and they speak to the many reasons that paintings and sculpture continue to represent and capture human likenesses and personalities. Privately collected, commissioned, or inherited, they have seldom, if ever, been seen in a public setting. The catalogue, which accompanies an exhibition at the National Portrait Gallery from April 1 through September 5, 2011, illustrates the portraits and recounts their histories, including comments by living sitters about having their portraits made.

Of all birdgroups, none is more closely associated with the world's tropical forests than trogons and quetzals. With shimmering golden-green feathers and long ornamental tail coverts, Central America's resplendent quetzal often has been called the world's most beautiful bird. Other New World as well as African trogonids also are iridescent and brightly pigmented, while red or reddish brown hues predominate in Asian species. Since deforestation and fires have ravaged many of the reclusive group's prime habitats, ornithologists and conservationists may soon be unable to study many of the world's trogonids in their native environments. Beautifully illustrated with color plates and line drawings, this comprehensive review of trogons and quetzals -- the first to be published in more than 150 years -- covers all thirty-nine extant species. The book includes detailed species accounts, range maps, and identification keys as well as a chapter that discusses comparative biology in terms of evolution, anatomy and morphology, behavior, ecology, breeding biology, and populations. Forty hand-colored plates -- most by the renowned nineteenth-century illustrator John Gould -- depict adults of both sexes; nineteen line drawings by author Paul Johnsgard illustrate behavior and anatomy. The book also includes more than three hundred bibliographic references. Despite their beauty and renown among birders, little has been previously published about the biology of many trogon and quetzal species. This up-to-date survey will serve as a valuable reference for ornithologists, conservationists, aviculturalists, and birdwatchers worldwide.

The development and operation of the Hubble Space Telescope (HST) have resulted in many rich legacies, most particularly in science and technology—but in culture as well. It is also the first telescope in space that has been utilized as effectively as if it were situated on a mountaintop here on earth, accessible for repair and improvement when needed. This book, which includes contributions from historians of science, key scientists and administrators, and one of the principal astronauts who led many of the servicing missions, is meant to capture the history of this iconic instrument. The book covers three basic phases of HST’s history and legacy: (1) conceiving and selling the idea of a large orbiting optical telescope to astronomers, the National Aeronautics and Space Administration, and the U.S. Congress, its creation as the HST, and its definition as a serviceable mission; (2) its launch, the discovery of the flawed mirror, the engineering of the mirror fix, subsequent servicing missions, decisions on upgrades, and the controversy over a “final” servicing mission; and (3) HST’s public image after launch—how the mirror fix changed its public image, how the HST then changed the way we visualize the universe, and how the public saved the final HST servicing mission. Collectively, this work offers a measured assessment of the HST and its contributions to science over more than 23 years. It brings together contributions from scholars, engineers, scientists, and astronauts to form an integrated story and to assess the long-term results from the mission.

Professor Noel D. Broadbent is one of Sweden's foremost experts on north Swedish archaeology and literally wrote the book on the prehistory of the Skellefteå region on the North Bothnian coast. This knowledge is now brought to bear on the issue of Saami origins. The focus is on the successful adaptive strategies of Saami societies over thousands of years - a testimony to Saami resiliency, of relevance to the survival of indigenous societies worldwide today.
