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

African Music     
JONES  A. M. 《African affairs》1949,48(193):290-297
The writer, of St. Mark's College, Mapanza, Northern Rhodesia,is the author of an essay on African music published by theRhodes-Livingstone Institute at Livingstone. He is a keen supporterof the African Music Society recently founded at Johannesburgby Mr. Hugh Tracey. Although he deals specifically with musicin Northern Rhodesia, he suggests there is evidence to showthat his statements apply in principle also to South and toWest Africa.  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

The impacts of quarterly adult arrest rates on later male serious delinquency prevalence rates were investigated in Philadelphia police districts (N = 23) over several years using all male delinquents aged 10–15 years who were mandated to more than “straight” probation. An ecological deterrence model expects more arrests to lead to less delinquency later. A community justice or mass incarceration model, the ecological version of general strain theory, and an ecologized version of the procedural justice model, each anticipates more arrests lead to more delinquency later. Investigating quarterly lags from 3 to 24 months between adult arrests and later delinquency, the results showed a time‐dependent relationship. Models with short lags showed the negative relationship expected by ecological deterrence theory. Models with lags of about a year and a half showed the positive relationship expected by the other three theories. Indicators needed so future works can gauge the relative merits of each theoretical perspective more accurately are described. The spatial distributions of current and 1920s delinquency rates were compared.  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
