In its statutory authority (National Science Foundation Act of 1950, as amended), the NSF is directed to both initiate and support basic scientific research. In its Ecology Program, one mode of initiating research is to en courage the development of new ideas through advisory workshops. The NSF is specifically directed to strengthen our nation's research potential. In addition, stimulating new approaches to research will continue to be prominent in the coming years as federal attention is given to increasing the innovativeness and competitiveness of the U. S. in science and engineering. A decision to initiate a workshop does not arise de novo in the Ecology Program. Rather, it emerges from panel discussions, conversations with in vestigators at meetings or on the phone, and from discussions between pro gram officers in the Division of Biotic Systems and Resources. This workshop was developed to provide advice to the NSF and the lim nological community. Some NSF perceptions on future funding for ecolog ical research on lake communities are presented here. Researchers often mentioned a paucity of innovative lake ecology at the community level. This perception was accompanied by a certain frustration since lakes probably have the best empirical data base of any natural environment and should continue to lead in the development of ecological concepts. Members of NSF advisory panels sometimes expressed similar concerns during consid eration of proposals for lake research.

Dr Tainter describes nearly two dozen cases of collapse and reviews more than 2000 years of explanations. He then develops a new and far-reaching theory.

In the United States, some populations suffer from far greater disparities in health than others. Those disparities are caused not only by fundamental differences in health status across segments of the population, but also because of inequities in factors that impact health status, so-called determinants of health. Only part of an individual's health status depends on his or her behavior and choice; community-wide problems like poverty, unemployment, poor education, inadequate housing, poor public transportation, interpersonal violence, and decaying neighborhoods also contribute to health inequities, as well as the historic and ongoing interplay of structures, policies, and norms that shape lives. When these factors are not optimal in a community, it does not mean they are intractable: such inequities can be mitigated by social policies that can shape health in powerful ways. Communities in Action: Pathways to Health Equity seeks to delineate the causes of and the solutions to health inequities in the United States. This report focuses on what communities can do to promote health equity, what actions are needed by the many and varied stakeholders that are part of communities or support them, as well as the root causes and structural barriers that need to be overcome.

What are the imagined communities that compel men to kill or to die for an idea of a nation? This notion of nationhood had its origins in the founding of the Americas, but was then adopted and transformed by populist movements in nineteenth-century Europe. It became the rallying cry for anti-Imperialism as well as the abiding explanation for colonialism. In this scintillating, groundbreaking work of intellectual history Anderson explores how ideas are formed and reformulated at every level, from high politics to popular culture, and the way that they can make people do extraordinary things. In the twenty-first century, these debates on the nature of the nation state are even more urgent. As new nations rise, vying for influence, and old empires decline, we must understand who we are as a community in the face of history, and change.

Questions of how the design of cities can respond to the challenge of climate change dominate the thoughts of urban planners and designers across the U.S. and Canada. With admirable clarity, Patrick Condon responds to these questions. He addresses transportation, housing equity, job distribution, economic development, and ecological systems issues and synthesizes his knowledge and research into a simple-to-understand set of urban design recommendations. No other book so clearly connects the form of our cities to their ecological, economic, and social consequences. No other book takes on this breadth of complex and contentious issues and distills them down to such convincing and practical solutions.

Vulnerable Communities examines the struggles of smaller cities in the United States, those with populations between 20,000 and 200,000. Like many larger metropolitan centers, these places are confronting change within a globalized economic and cultural order. Many of them have lost their identities as industrial or commercial centers and face a complex and distinctive mix of economic, social, and civic challenges. Small cities have not only fewer resources but different strengths and weaknesses, all of which differentiate their experiences from those of larger communities. Vulnerable Communities draws together scholars from a broad range of disciplines to consider the present condition and future prospects of smaller American cities. Contributors offer a mix of ground-level analyses and examinations of broader developments that have impacted economically weakened communities and provide concrete ideas for local leaders engaged in redevelopment work. The essays remind policy makers and academics alike that it is necessary to consider cultural tensions and place-specific conflicts that can derail even the most well-crafted redevelopment strategies prescribed for these communities.
