While organized crime has an impact on youth that is both broad and direct, frequently it has a more substantial impact as a consequence of its indirect effects that are noted particularly at the community level. This report explores the impact of both traditional and non-traditional organized criminal activities on youth. It also discusses the effect of organized crime on public perception, vulnerable youth populations, and police resource allocation including both supply and demand reduction measures. The research on organized crime in this context is limited in a number of areas. Further research on the impact of organized crime on youth, for example, should include issues related to public perception and the collection of appropriate data. An ethnographic approach could also help expand our understanding of some of the impacts. Policy regarding internal (police) and external (public) communication of the local impact of organized crime should be examined, as well as that related to data entry, police resource allocation, and the issue of supply and demand reduction.  相似文献

Dams have displaced millions of people in many countries of the world, but such social costs of dam construction constitute a relatively new international issue. The emergence of displacement as a salient issue is explained with reference to three factors: historical circumstances, political leaders' ability to mobilize support for their priority concerns and to public participation. Participation refers to both the public's action to influence critical policy decisions and to its sense of efficacy. Cases are considered in three major dam‐building countries: the United States, India and China. In the United States, social displacement never became a public or political issue. Instead, dams have been challenged on environmental grounds. In India, by contrast, dams have stirred enormous controversy due to their social costs. The article also considers experience in China, site of the world's largest dam project, and the recent report of an international commission, the World Commission on Dams. The report's release in November 2000 marks the emergence of social displacement as a global concern. Copyright © 2001 John Wiley & Sons, Ltd.  相似文献

In this response to an article by Holly High, “The Implications of Aspirations: Reconsidering Resettlement in Laos,” published in Critical Asian Studies in December 2008 (vol. 40, no. 4, pp. 531–50), the authors do not dispute the notion that many people in Laos have aspirations for modernity and development. However, they are at odds with High in two key ways. First, she only presents a selective reading of authors who have written critically about highland to lowland resettlement in Laos, thus misrepresenting some of their ideas. Second, the empirical evidence High provides is insufficient or inappropriate to support her argument that people who are being resettled from the uplands to the lowlands in Laos are supportive of these state-sponsored schemes because they fit with their aspirations for modernity. The authors are concerned that High's article may inadvertently serve to justify the views of those who advocate and fund centrally planned resettlement of ethnic minorities in Laos and who believe that non-participatory and top-down resettlement is acceptable if increased funding is available and better planning is conducted, even when those targeted for relocation would rather not move.  相似文献

Abstract

Housing quality and affordability are growing concerns in rural areas, particularly in regions affected by economic restructuring and population decline. This article uses data from the U.S. Department of Housing and Urban Development to assess changes in the characteristics of nonmetropolitan public housing residents in the Great Plains between 1977 and 1996.

Results indicate that public housing occupants were younger and more racially diverse in 1996 than in 1977. Also, a larger proportion received welfare benefits in addition to housing supplements. (In 1977, few households received both types of assistance.) Regression models reveal a significant positive relationship between changes in county population, unemployment rates, and economic designation and minority representation in public housing. Implications include the need for flexible measures that meet the changing needs of subsidized households. The characteristics of these households in the Great Plains region indicate the need for both region‐specific and coordinated housing and welfare policies.  相似文献

Cuba has effectively implemented a system of popular mobilization and education to prepare people for such natural disasters as hurricanes. Compliance with evacuation orders is impressive. Top priority is attached to saving lives. The country's acclaimed programme accounts for the limited toll of Hurricane Michelle in November 2001, which was the most powerful storm since 1944. Five Cubans died in the storm, which wreaked havoc in Jamaica, Honduras, and Nicaragua. This article reviews recent Cuban experience in disaster preparedness, which was achieved despite material scarcity. Since the prestigious Intergovernmental Panel on Climate Change warns of increased susceptibility to disasters in future, Cuba's record deserves wide attention.

Urine morphine levels after the consumption of poppy seeds were measured in two separate trials. Maximum levels of approximately 18 micrograms/ml were found using RIA, EMIT-ST and GC methodologies. Positive immunoassay results were seen up to 60 h post-ingestion. Several different lots of seeds from various sources were assayed for morphine and found to range from 4-200 mg/kg. Differentiation of poppy seed eaters from opiate users was not possible via the identification of minor alkaloid constituents of poppy seeds. It is, however, possible to analyse opiate urines with respect to 6-O-acetylmorphine. Below the level of approximately 5 micrograms/ml total opiates, GC/MS is the method of choice for this analysis.  相似文献
