While a quarter of a century of contributions to the literature on central city-suburb relationships indicates that within a metropolitan context suburban exploitation of central cities may not exist, there is no lessening of the desire to reduce imbalances within a particular urban service delivery sector. This paper assesses the impact of an urban administrative policy intervention aimed at shifting the burden of supporting a municipal service to those who actually use and benefit from it. An interrupted time-series quasi-experimental design is merged with a data analysis strategy employing integrated moving average models. The evidence endorses the adoption of user charges for certain urban services as an effective strategy open to urban bureaucracies for redressing urban public finance imbalances.This paper is a revision of a draft originally prepared for presentation in the session, The Sociologist as Evaluator: Policy Direction from Social Science, at the Southwestern Social Science Meetings, April, 1978 in Houston, Texas. 相似文献

Concentrating on the health sector, this article argues that the provision of collective goods through external actors depends on the level of state capacity and the complexity of the service that external actors intend to provide. It shows that external actors can contribute most effectively to collective good provision when the service is simple, and that simple services can even be provided under conditions of failed statehood. Effectively delivering complex services requires greater levels of state capacity. The article also indicates that legitimacy is a key factor to explain variance in health service delivery. To demonstrate this, the article assesses health projects in Somalia. It shows that simple services—malaria prevention and tuberculosis control—are provided effectively in all three Somali regions, including the war‐torn South‐Central region. In contrast, the HIV/AIDS project only achieved substantial results in Somaliland, the only region with a comparatively higher level of state capacity, and failed in the South‐Central region and Puntland. 相似文献

A sample of 1176 males from 10 Italian regions have been typed for DYS19, DYS389-I, DYS389-II, DYS390, DYS391, DYS392, DYS393, and DYS385. Individual haplotype data are available on line. A low degree of variation is present among regions. Use of this database is specifically recommended for forensic applications in Italy. 相似文献

Understanding and addressing the consequences of partisan animosity requires knowledge of its foundations. To what extent is animosity between partisan groups motivated by dislike for partisan outgroups per se, policy disagreement, or other social group conflicts? In many circumstances, including extant experimental research, these patterns are observationally equivalent. In a series of vignette evaluation experiments, we estimate effects of shared partisanship when additional information is or is not present, and we benchmark these effects against shared policy preference effects. Partisanship effects are about 71% as large as shared policy preference effects when each is presented in isolation. When an independently randomized party and policy position are presented together, partisanship effects decrease substantially, by about 52%, whereas policy effects remain large, decreasing by about 10%. These results suggest that common measures of partisan animosity may capture programmatic conflict more so than social identity–based partisan hostility. 相似文献
