Present policy issues concern the reduction of ozone levels by controlling its precursors, NO_x and volatile organic compounds (VOC). VOC are emitted from anthropogenic and biogenic sources. Whereas our understanding of VOC emissions from anthropogenic sources has advanced significantly in recent years, there is still a lack of knowledge concerning the contribution of biogenic VOC to the budget of organic trace gases and their impact on the formation of ozone in the troposphere. Improving ozone reduction strategies in the future requires a detailed understanding of the...

Through explorations of six cases taken from various Latino ethnic groups, this book advances our understanding about meanings of Latino manhood and masculinities. The studies range from theatre and literature to men's activism and sports, showing how masculinities are embodied and performed.

During the 1950s, leading American scientists embarked on an unprecedented project to remake high school science education. Dissatisfaction with the 'soft' school curriculum of the time advocated by the professional education establishment, and concern over the growing technological sophistication of the Soviet Union, led government officials to encourage a handful of elite research scientists, fresh from their World War II successes, to revitalize the nations' science curricula. In Scientists in the Classroom, John L. Rudolph argues that the Cold War environment, long neglected in the...
