The bureaucracy's masters have redesigned the American political system over the past 20 years. As before, checks and balances play a critical role. This time, however, relations between one branch of government (the bureaucracy) and the rest are decidedly and deliberately asymmetrical. While acknowledging the need for bureaucratic accountability, the author raises questions about a growing emphasis on highly coercive controls from above. Instead he recommends greater reliance on catalytic controls from below, which energize the bureaucracy without stifling bureaucratic creativity and eroding bureaucratic integrity.  相似文献

I never really ate Chinese food before coming to China. That's the conclusion I reached many years ago, after my first visit to the PRC. I had long enjoyed the tasty, somewhat exotic delights of suburban Chinese restaurants in the US: limpid mo-shoo pork, the pu-pu platter, sau-téed meat in a heavy sauce with canned pineapple chunks, and of course the fortune cookie -the ubiquitous after-dinner treat which, to Chinese people, is an overseas idiosyncrasy. But this is not really Chinese food. My memories of Chinese dishes outside of China are pretty repetitive. Regardless of which item you order, it seems always to be more or less the same, plus or minus broccoli and snow peas.  相似文献

Despite substantial public, political, and scholarly attention to the issue of immigration and crime, we know little about the criminological consequences of undocumented immigration. As a result, fundamental questions about whether undocumented immigration increases violent crime remain unanswered. In an attempt to address this gap, we combine newly developed estimates of the unauthorized population with multiple data sources to capture the criminal, socioeconomic, and demographic context of all 50 states and Washington, DC, from 1990 to 2014 to provide the first longitudinal analysis of the macro‐level relationship between undocumented immigration and violence. The results from fixed‐effects regression models reveal that undocumented immigration does not increase violence. Rather, the relationship between undocumented immigration and violent crime is generally negative, although not significant in all specifications. Using supplemental models of victimization data and instrumental variable methods, we find little evidence that these results are due to decreased reporting or selective migration to avoid crime. We consider the theoretical and policy implications of these findings against the backdrop of the dramatic increase in immigration enforcement in recent decades.  相似文献

Agricultural extension is in transition worldwide. Governments and international agencies are advancing structural, financial and managerial strategies to reform extension. This article reviews and analyses these reform measures, concluding with a conceptual framework that is intended to underscore at once the diversity and interconnectedness of these structural, financial and managerial strategies for decentralizing public sector agricultural extension.  相似文献

Attempts to integrate the two predominant spatial theories of crime, social disorganization and routine activity theories, may benefit from examining empirical relationships at units of analysis smaller than the relatively large units characteristic of most ecological research (cities, SMSAs, census tracts, multiple city blocks). Small units of analysis, specifically, face blocks (both sides of a city block between two intersections) are analyzed in a study of street robbery within a medium-size southeastern U.S. city. Models of street robbery and street-robbery "potential" suggest a crime diffusion process. Several interaction effects between variables of social disorganization and routine activity theory are found, which may form the basis in future research for successful theoretical integration.  相似文献

We investigate the evolution of political campaign coverage through a content analysis of the topics highlighted in newspapers' agendas during three presidential elections in Chile. Results show an expected increase in the space allocated to the politicians' private lives (privatisation) by 2009, but no change in the attention given to individual politicians' political traits (political competence). Coverage of candidates' campaign strategies had increased markedly in media agendas by 1999, and by 2009 in politicians' agendas. These changes are consistent with some of the recent transformations of political communication in Western democracies, within the framework of the so‐called ‘mediatisation’ of politics.  相似文献
