Social capital has attracted increasing attention in recent years. We use county-level and individual survey data to study how Wal-Mart affects social capital. Estimates using several proxies for social capital—such as club membership, religious activity, time with friends, and other measures—do not support the thesis that “Wal-Mart destroys communities” by reducing social capital. We measure exposure to Wal-Mart two ways: Wal-Marts per 10,000 residents and Wal-Marts per 10,000 residents aggregated over the years since 1979 to capture a more cumulative “Wal-Mart Effect.” We find that the coefficients on Wal-Mart’s presence are statistically insignificant in most specifications. 相似文献

A prominent change in American electoral institutions occurred when the 17th Amendment to the Constitution established direct election of U.S. Senators as of 1914. How did this change the political agency relationship between the mass electorate and U.S. Senators? We develop theoretical expectations about the representational effects of direct election by a relatively inexpert mass electorate and indirect election by a relatively expert political intermediary, based on principal‐agent theory. The chief predictions are that the representative will be more responsive to the mass electorate under direct election, but will also have more discretion to pursue his or her own ends. We use the 17th Amendment as a quasi‐experiment to test the predictions of the theory. Statistical models show strong support for both predictions. Moreover, the 17th Amendment is not associated with similar changes in the U.S. House of Representatives—as expected, since the amendment did not change House electoral institutions. 相似文献

The idea of radically extending average human life expectancy is an ancient one, but for most of human history exceedingly
utopian. There is now, however, a revival of that idea, with some scientists and others arguing that it is possible and desirable.
But the main problem with most of the life extension enthusiasm is that it is based almost entirely on the desire of some
individuals to make it happen. The social consequences of success of such a venture are, however, either ignored altogether
or dismissed on the grounds that any problems can be dealt with. In the end, none of our present human and social problems
would be helped by radically longer lives and no obvious social benefits have been advanced to support it.

Changes in immigration laws over the last three to four decades have given rise to unprecedented numbers of undocumented children.
However, as others have argued, policies regarding the control of undocumented migration have had deleterious effects on undocumented
children and their basic access to social rights. Undocumented youth in the United States can legally attend K-12 education,
but cannot legally work, vote, receive financial aid, or drive in most states. Their situation calls for a reexamination of
immigration laws and a recasting of the frame that has been used to promote their inclusion.
R. G. Gonzales is an Assistant Professor at the University of Washington School of Social Work. His current recent research examines the role of policy and mediating institutions in shaping the on-the ground realities and options available to unauthorized Mexican youth as they transition to adulthood. 相似文献

Modern democracies increasingly confuse civic or political equality with a radical relativism that calls into question legitimate
principles of hierarchy and the very idea of reasonable value judgments. This confusion reflects a “corruption,” in Montesquieu’s
sense, of democracy rooted in a refusal to recognize distinctions that are integral to both human nature and social life.
A moderate form of cultural relativism is a genuine intellectual achievement that helps combat ethnocentrism and allows one
to better appreciate the full range of human experience. But criteria of meaning and truth are by no means entirely dependent
upon cultural context. Our contemporary awareness of the “relativity” of cultures and historical experiences must be complemented
by a robust appreciation of the universality of Reason and citizenship.

Over twenty years ago my book The Last Intellectuals put into circulation the phrase “public intellectual.” The term unexpectedly enjoyed great success. It encapsulated a new
division between a professional or academic intellectual focused on his or her specialty and an intellectual orientated to
a larger public. The former tend to disappear into the university, while they latter write for the educated public. In the
twenty years since its publication, my book has been sharply challenged. Moreover the emergence of African-American and women
intellectuals, and well as new developments such as Internet, have possibly undermined my thesis. Yet these phenomena amount
to revisions, not refutations, of my thesis. Moreover the role of intellectuals in France and Germany suggest that the same
process of academization is taking place in other advanced industrial nations. What is called for is not nostalgia or its
opposite, a celebration of everything that happens, but a consideration of the real shifts that affect the lives and work
of intellectuals.

As Leon Kass has noted, the conquest of illness and death has long been “the unstated but implicit goal of modern medical
science.” But it is unstated no more. Since the late 1990s, a new generation of scientists and enthusiasts has emerged to
proclaim the feasibility and desirability of radical life extension. What they promise is not just longer life, better health,
and heightened vitality, but a transformation of ourselves into the sort of beings we have long wished to be, but have repeatedly
failed to become: beings who are completely fulfilled and living in perfect harmony with others. Despite the obvious and profound
appeal of such a fantasy, attempts to realize it, even if successful scientifically, might prove to be disastrous culturally,
for reasons that go beyond concerns about the alteration of existing social structures. Ultimately, as Freud argued, life
might well become stagnant, “shallow and empty,” while the fear of death might become all the more crippling.

Environmental markets have several institutional features that provide a new context for the use of auctions and that have not been studied previously. This paper reports on laboratory experiments testing three auction forms—uniform and discriminatory price sealed‐bid auctions and an ascending clock auction. We test the ability of subjects to tacitly or explicitly collude in order to maximize profits. Our main result is that the discriminatory and uniform price auctions produce greater revenues than the clock auction, both with and without explicit communication. The clock appears to facilitate successful collusion, both because of its sequential structure and because it allows bidders to focus on one dimension of cooperation (quantity) rather than two (price and quantity).© 2009 by the Association for Public Policy Analysis and Management. 相似文献

This paper explores whether an individual’s news source can explain their attitudes on immigration. We focus on the Spanish-speaking
population in the U.S., since they have the option of accessing their news in English, Spanish or in both languages. Our audience influence hypothesis predicts that Spanish-language news will cover immigration in a more positive and informative manner than will English-language
news. Thus, Latinos who use Spanish-language news may have a higher likelihood of possessing pro-immigrant sentiments than
Latinos who only use English-language news. Content analysis of Spanish and English-language television news segments reveals
variations in the tone and substance of these news outlets. Analysis of Latino survey respondents indicates that immigration
attitudes vary by news source. Generational status also influences Latinos’ immigration attitudes, though its impact is not
as great as one’s news source.
