The U.S. electric power sector has experienced a substantial shift of the generation mix since the turn of the century, moving from heavy reliance on coal‐powered generation to one drawing more from natural gas and, more recently, renewables. This transition has been forged by a mix of macroeconomic factors (recession and recovery); technological breakthroughs (horizontal drilling coupled with hydraulic fracturing; improvements in natural gas plant efficiency); clean energy policies at federal, state, and local levels of government; and private sector demands for carbon‐free energy sources. These factors have combined to reduce carbon emissions from electric power generation substantially this century. In this article we examine the extent of this transition, its causes, as well as the distinct American institutional factors steering it, including energy and environmental federalism, electoral politics, and the political economy of clean energy policy enactment and resistance. 相似文献

In this paper, we develop and test a general measure of policyexpenditures in the American states. Our approach is to constructa spatial proximity model of yearly state program spending.The empirical analysis reveals that state spending patternsvary along a clear and readily-interpretable unidimensionalcontinuum which differentiates policies that provide particularizedbenefits to needy constituencies from policies that providebroader collective goods. Based upon standard evaluative criteria,the variable created from our model possesses some highly desirablecharacteristics. And, it compares favorably to other measuresof state policy activity. The net result is a yearly score foreach state which summarizes that state's spending across allmajor program areas. More generally, we believe that our variablecan be interpreted as valid and reliable representational measurementof state policy priorities. In this capacity, it could occupyan important position within models of state politics.
Author's note: Many colleagues provided useful feedback on earlierversions of this paper. We particularly appreciate the excellentcomments and suggestions from Robert Erikson, Richard Fording,Kim Hill, David Lowery, Andrea McAtee, and George Rabinowitz.We would also like to thank Daniel Lewis and William Myers fortheir assistance with the data collection.

It is understandable that Iran’s December 2006 hosting of an international conference casting doubts on the historicity of
the Holocaust would raise questions about treatments of the Shoah elsewhere in the Third World. In fact, indigenization the
Holocaust—the manifold ways in which serious scholars, activists, and writers from Asia, Africa, and Latin America have come
to incorporate the Holocaust in their intellectual work—has been positive overall. Within the framework of intellectual globalization,
much of the Third World intelligentsia has come to include this most Western of human rights violations within the framework
of their own cultures and histories. Although some of the indigenization of the Holocaust is political and instrumental, the
deviant variant expressed at the Tehran Holocaust conference is atypical. Governmental respect for the memory of victims of
genocide should be considered as an emerging human right. 相似文献

The National Oceanic and Atmospheric Administration instituted a Planning, Programming, Budgeting, and Execution System (PPBES) in 2002. As supplemented by matrix management, PPBES was appealing as an effort to rationalize the performance of an agency with an especially high degree of functional overlap among its component parts. Although PPBES has had some salutary effects, the agency's experience to date consistent with accounts of the difficulties that led to the abandonment of program budgeting by the civilian bureaucracy almost 40 years ago. As such, it speaks to the limits of performance assessment as a means of reallocating resources and responsibilities across organizational boundaries. 相似文献

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

The aim of this five-wave longitudinal study was to investigate the relationship between anxiety and adolescent identity development.
Participants were 1,313 adolescents who annually completed measures of anxiety and identity. Growth Mixture Modeling (GMM)
analyses demonstrated that the adolescent population was best typified by two latent growth trajectory classes: a low anxiety class (n = 1,199) characterized by a low initial level of anxiety that decreased over time and a high anxiety class (n = 114) characterized by a higher initial level of anxiety that increased over time. To answer our research question, we tested
a model in which the anxiety classes predicted initial levels and rates of change of three identity dimensions: commitment,
in-depth exploration, and reconsideration of commitment. Findings indicated that the high anxiety adolescents displayed a
more troublesome identity development than their low anxiety peers, since their commitments became weaker with age, and they
reconsidered them intensively.

Considerable research has focused on the reliability and validity of informant reports of family behavior, especially maternal
reports of adolescent problem behavior. None of these studies, however, has based their orientation on a theoretical model
of interpersonal perception. In this study we used the social relations model (SRM) to examine family members’ reports of
each others’ externalizing and internalizing problem behavior. Two parents and two adolescents in 69 families rated each others’
behavior within a round-robin design. SRM analysis showed that within-family perceptions of externalizing and internalizing
behaviors are consistently due to three sources of variance; perceiver, target, and family effects. A family/contextual effect
on informant reports of problem behavior has not been previously reported. 相似文献
