Abstract This article analyzes the extent to which systematic spatial variations in opportunities in metropolitan areas provide a persuasive rationale for three current strategies for stimulating the development of urban communities: enterprise zone programs, community development financial institutions, and community development corporations. It examines whether the strategies are appropriately designed to respond to serious deficiencies in opportunities in distressed inner cities and reviews available evidence about their efficacy in addressing those deficiencies. A review of the literature reveals that poor inner‐city neighborhoods, particularly communities of color, have unequal access to opportunities in numerous areas, including employment, credit and financial services, housing, neighborhood shopping, and social networks and services that provide access to information and resources. The limited best‐case evidence indicates that the three strategies vary greatly in their ability to address these inequalities. 相似文献

Two cases of fatal overdose with morphine are presented. Large amounts of the drug were involved in both cases, one by oral ingestion, the other by intravenous injection. Morphine concentrations in various body fluids and tissues are compared to those in the literature. 相似文献

The chemical substances of perspiration found in latent fingerprint residue may hold the key for dating latent fingerprints. To study the chemical transformations of these components as a function of time and environment, fingerprint residues from four males and four females were analysed by thin-layer chromatography (TLC) and high performance liquid chromatography (HPLC). Three major and two or three minor components were detected by both methods and the variation in the quantity of the major components with time was observed. 相似文献

Over the past decade, the proliferation of election surveys has worked to undergird the electoral system in Mexico and to make electoral fraud more difficult. In the presidential elections of 1994, significant controversies arose as to survey methodologies, but by the congressional elections of 1997 the fierce debates over methodologies had subsided. Substantively, the surveys confirm the accuracy of the vote count in 1998, allow profiles of voters to be constructed for the three most important parties and mark declines in the support of the once dominant Partido Revolucionario Institucional. 相似文献

The number of deaths as a consequence of orphenadine poisoning seems to increase, mostly among severely psychotic males. The lethal dose corresponds to the weekly average dose used in the treatment of neuroleptic extrapyramidal side effects. Based on the literature, the serious, rapidly incipient, cardiac, and neurologic symptoms of poisoning are emphasized. The handing out of orphenadine to suicidal persons must be restricted, and even small overdoses (1-2 g) ought to result in the immediate initiation of observation at an intensive care unit. 相似文献
