From its founding in the late 1800s through the 1950s, Brownsville, a section of eastern Brooklyn, was a white, predominantly Jewish, working-class neighborhood. The famous New York district nurtured the aspirations of thousands of upwardly mobile Americans while the infamous gangsters of Murder, Incorporated controlled its streets. But during the 1960s, Brownsville was stigmatized as a black and Latino ghetto, a neighborhood with one of the city's highest crime rates. Home to the largest concentration of public housing units in the city, Brownsville came to be viewed as emblematic of urban decline. And yet, at the same time, the neighborhood still supported a wide variety of grass-roots movements for social change.

The story of these two different, but in many ways similar, Brownsvilles is compellingly told in this probing new work. Focusing on the interaction of Brownsville residents with New York's political and institutional elites, Wendell Pritchett shows how the profound economic and social changes of post-World War II America affected the area. He covers a number of pivotal episodes in Brownsville's history as well: the rise and fall of interracial organizations, the struggles to deal with deteriorating housing, and the battles over local schools that culminated in the famous 1968 Teachers Strike. Far from just a cautionary tale of failed policies and institutional neglect, the story of Brownsville's transformation, he finds, is one of mutual struggle and frustrated cooperation among whites, blacks, and Latinos.

Ultimately, Brownsville, Brooklyn reminds us how working-class neighborhoods have played, and continue to play, a central role in American history. It is a story that needs to be read by all those concerned with the many challenges facing America's cities today.

Although bats and dolphins live in very different environments, are vastly different in size, and hunt different kinds of prey, both groups have evolved similar sonar systems, known as echolocation, to locate food and navigate the skies and seas. While much research has been conducted over the past thirty years on echolocation in bats and dolphins, this volume is the first to compare what is known about echolocation in each group, to point out what information is missing, and to identify future areas of research.

Echolocation in Bats and Dolphins consists of six sections: mechanisms of echolocation signal production; the anatomy and physiology of signal reception and interpretation; performance and cognition; ecological and evolutionary aspects of echolocation mammals; theoretical and methodological topics; and possible echolocation capabilities in other mammals, including shrews, seals, and baleen whales. Animal behaviorists, ecologists, physiologists, and both scientists and engineers who work in the field of bioacoustics will benefit from this book.
