For mitigating climate change and adapting to whatever impacts we cannot avoid, there are no politically feasible alternatives to improvements in the U.S. Climate Change Action Plan at this time or for the foreseeable future. Yet improvements in the Action Plan have been obstructed by the diversion of attention and other resources to negotiating a binding international agreement, to developing a predictive understanding of global change, and to documenting the failure of the Action Plan to meet its short-term goal for the reduction of aggregate greenhouse gas emissions. Continuous improvements depend upon reallocating attention and other resources to the Action Plan, and more specifically, to the many small-scale policies that have already succeeded by climate change and no regrets criteria under the Action Plan. Sustaining the effort over the long term depends on harvesting experience from these small-scale successes for diffusion and adaptation elsewhere on a voluntary basis.  相似文献

Has there been a structural change in the way U.S. presidents use force abroad since the nineteenth century? In this article, I investigate historical changes in the use of force by U.S. presidents using Bayesian changepoint analysis. In doing so, I present an integrated Bayesian approach for analyzing changepoint problems in a Poisson regression model. To find the nature of the breaks, I estimate parameters of the Poisson regression changepoint model using Chib's (1998) hidden Markov model algorithm and Frühwirth‐Schnatter and Wagner's (2006) data augmentation method. Then, I utilize transdimensional Markov chain Monte Carlo methods to detect the number of breaks. Analyzing yearly use of force data from 1890 to 1995, I find that, controlling for the effects of the Great Depression and the two world wars, the relationship between domestic conditions and the frequency of the use of force abroad fundamentally shifted in the 1940s.  相似文献

This research updates and extends John Crittenden's effort toidentify the dimensions of modernization among the U.S. states.The objective is to determine the degree of continuity or changein the structure of modernization between 1960 and 1990. Weundertake a principal-axis factor analysis of the same thirty-threevariables Crittenden employed in his analysis of state modernization.In addition to comparing the results of factor analyses forthe two periods, we offer an index of state modernization for1990. The outcome of the 1990 factor analysis parallels thestructure identified for the earlier period. Four primary factorsemerge-metro-urbanism: Migratory Pull, Political Participation(Integrative Message Exchange for 1960), and Decentralization(new for 1990). The overall index of state modernization showsNew York, California, New Jersey, Connecticut, and Coloradoas the most developed states.  相似文献

This article examines changes in the background characteristics, attitudes, and behavior patterns of high-level U.S. federal executives. It also considers the impact of the New Public Management (NPM) movement. The data indicate that despite intense struggles about the role of the public sector, top civil servants remain a well-educated, experienced, and highly motivated group, the members of which compare favorably to top executives in the private sector. The data also suggest that the Civil Service Reform Act (CSRA) of 1978 has been effective in producing a more politically responsive corps of career civil servants, and that administrators (both career and noncareer) are increasingly attuned to the more technical and legal aspects of their roles and less oriented to protecting particular interests or clientele groups. NPM-style changes are still in progress and remain controversial, but it appears that political leaders continue to have an excellent (and increasingly diverse) group of career people to work with and a system that—at least in part due to the CSRA reforms—is more responsive to them than before. The top part of the U.S. bureaucracy may have been bent and reshaped in many ways over the last thirty years, but, despite widely publicized fears, it has not broken.  相似文献

Punctuated equilibrium theory (PET) suggests that the policy process is characterized by long periods of incremental change and short periods of punctuated change. The impetus for the latter is usually a focusing event that breaks open policy monopolies, allowing for major changes in legislative decision making. While a burgeoning body of literature, a shortcoming in the PET literature is that it has yet to explain why focusing events and subsequent breakdowns in policy monopolies sometimes fail to result in punctuated policy. We integrate theories on cultural change with punctuated equilibrium to explain why focusing events do not always result in the dramatic policy changes that we might expect. Specifically, we use the context of national energy policy and the lexical database, Google Ngram Viewer, to trace punctuating energy‐related events and the occurrence or lack thereof subsequent policy change from 1952 to 2000.  相似文献

The U.S. Global Change Research Program (USGCRP) was established in law in 1990 (P.L. 101–606) with a mandate to provide policymakers with usable information. The law gave a White House Committee on Earth and Environmental Sciences (CEES) responsibility to implement the program with respect to its policy mandate. In 1994 CEES was replaced, in part, because it failed to provide usable information. This article, documenting the development of the program's policy mandate and CEES implementation of the USGCRP, finds a performance shortfall. The shortfall is attributed to a breakdown in the legislative process, participant perspectives, and the structure of post-World War II science policy. The purpose of the article is to explain the CEES performance shortfall in hope that its successor can improve USGCRP performance with respect to its legal mandate based upon the lessons of experience.  相似文献

The president's budget is a political document, a prediction and an institution. As a political document, its version of the past and vision of the future are open to criticism. As a prediction, its projections arguable in the light of experience and professional judgment. As an institution, its contribution to the general capacity of government is subject to debate.  相似文献

The economic and political ramifications of immigration will become increasingly evident in the United States during the coming decade, particularly in view of recent immigration policies that guarantee that the magnitude and diversity of the inflow will continue to grow. This symposium presents research that examines the role of immigrants in industrial restructuring and evaluates the effects of the 1986 Immigration Reform and Control Act. The importance of English language skills for economic advancement, and of government-supported training for refugees, are also examined. Together, this body of research directs our attention to the need for a more active public and private sector role in assisting all U.S. workers prepare for the demands of the labor market of the future.  相似文献
