The American electric utility industry is entering a moment of transition. Once viewed as a stable and secure consortium of
publicly regulated monopolies that produce and distribute electricity, the industry has weathered market restructuring only
to face the ever-present risk of natural disasters, price fluctuations, terrorist attacks, and blackouts. This paper uses
five criteria—technical feasibility, cost, negative externalities, reliability, and security—to evaluate the broad portfolio
of energy technologies available to American electricity policymakers. Upon close inspection, energy efficiency practices,
renewable energy systems, and small-scale distributed generation technologies appear to offer many advantages over large and
centralized nuclear and fossil fueled generators. Contrary to the mimetic commentary produced by the media, these three approaches
would present policymakers a superior alternative for curbing electricity demand, minimizing the risk of fuel interruptions
and shortages, helping improve the fragile transmission network, and reducing environmental harm 相似文献

The Social Logic of Politics places social learning at the center of political choice. People develop their political preferences,
knowledge, values, perceptions of ability, and decisions about political behavior in interactions with others, usually members
of their social circles. Political attitudes and goals are not derivatives of exogenous economic preferences. They are not
the results of careful calculations, in which optimization of personal needs guides the mode of reasoning. This theoretical
stance draws sustenance from recent work across the social science, even as it harkens back to established, if neglected principles
of political analysis.
My thanks to Rüdiger Schmitt-Beck for his encouragement and for the critical comments of several anonymous referees and to
Josip Dasović and Jennifer Fitzgerald, my co-authors of Partisan Families: the Social Logic of Bounded Partisanship in Germany
and Britain (Zuckerman et al. 2007). Material from that book appears in this essay. 相似文献

We examine the factors that improve the candidates’ likelihood of winning an election by drawing on information from campaign resources used by candidates running in the 2002 French parliamentary election. The main effects that we wish to analyze are the candidates’ gender, political affiliation and possible incumbency. We find that the contributions the candidates received and their political affiliations determine their acceding to the second round of the elections. But surprisingly once they make it to the second round, the contributions cease to be relevant; only the candidates’ gender, incumbency and the actual spending rather than the contribution levels matter. 相似文献

We use economic theory to examine the intensity of fundamentalist sects in which leaders work to enhance their followers’ observance level. We model three stylized situations under which fundamentalist groups function, examining the intensity of observance in each. We find that, under reasonable conditions, rivalry among fundamentalists makes them more extreme. 相似文献

Liberal Democrat policy has been labelled as social democratic, yet the party has been reluctant to so describe itself. Taking Crosland's The Future of Socialism as a reference point, there appears to be much shared ground between social democracy and Liberal Democrat policy. Meanwhile, the party's tax policy adopted in 2006 takes the Croslandite approach of taxing wealth rather than income. Despite this, the article argues that the party is a social liberal rather than a social democratic one. These two political philosophies have so much in common that it is understandable that some commentators see the influence of social democracy where they might instead perceive social liberalism. Yet the two differ in their attitudes to the state. Both see a positive role for the state in furthering social goods. However, social liberalism shares classical liberal concerns about the dangers of an over-mighty state. This approach underpins Liberal Democrat policy. 相似文献

Detective stories take place mainly in two settings, constantly changing, many faceted big cities filled with strangers, and
stable, fairly homogeneous, innocent small towns whose members know one another. The differences in each clarify the qualities
of the other. In solving the mystery of the small town, the detective provides moral instruction and restores the town’s innocence.
In solving the mystery in the big city the detective reveals the city as part of the mystery and provides the reader with
temporary orientation to the city. Mysteries have grown with the growth of the cities and now appear in every country of the
world.
Harold J. Bershady is an emeritus Professor of Sociology at the University of Pennsylvania. His most recent book, edited with
Renée Fox and Victor Lidz, is After Parson: A Theory of Action for the 21st Century, published by Russell Sage Press, 2005. 相似文献
