Grassroots environmental activism among Latin America's poor has altered the debate over environmental policy, social welfare, and citizenship. Yet the question remains whether this social mobilization of the poor is part of a larger trend toward broader environmental concerns and democratic political participation, or a shortlived movement susceptible to the same pressures that have dissolved community mobilization in the past. This article compares Brazil with other Latin American and European countries in surveys of environmental awareness, concerns, and reported behavior. It finds that Brazilians residing in the urban periphery link their own local environmental concerns to more global considerations, and that concern for and activism on environmental issues is positively related to wider community involvement.  相似文献

This paper concerning the public school adjustment of delinquent boys after release from a juvenile corrective institution is based on research data obtained as part of a followup study. Seventy-two percent of the 94 teenage boys in our sample returned to school in the community, but over three-fourths of them dropped out. Although we examined several factors associated with the boys' post-release school adjustment, we focused our inquiry on the small group of 14 boys who completed high school. A few personal and social factors were related to public school outcome, i.e., whether the boys graduated or not. However, we also found that all the boys who finished high schol had received some suppoprt from a structured environment or from interested people in contrast to a majority of the boys who dropped out. None of the boys who graduated was involved in antisocial behavior while in school and only two, or 14%, had gotten into serious legal trouble during the 3-year followup period in comparison to 40% of the boys who dropped out and 50% of those who never attended school after release.Received Ph.D. from University of Houston in 1956.

Propylene glycol (PG), a widely used solvent and lubricant, is thought to have low toxicity when ingested. Three cases were identified where PG, either alone or in combination with other chemical agents, contributed to death. The decedent in whom PG was the sole agent was a 32-year-old schizophrenic man with cardiomegaly and renal impairment. The blood PG concentration was 4410 mg/L at least 9.5 h following ingestion.  相似文献

The authors are involved in the extraction of DNA material from calcified tissues, oftentimes teeth, and analysis of such material to assist the investigative process, frequently by confirming the identity of the victim. Biologic or molecular techniques for the purposes of human identification have evolved to allow increasingly discriminating tests for use in criminal and noncriminal death investigations, as well as paternity disputes. The goal of such tests is to either include 2 samples (ie, they are from the same person, or in the case of paternity, they are from related individuals) or exclude 2 samples (ie, they are from different people or from unrelated individuals). Regardless of the system used and when data error has been eliminated, an exclusionary conclusion is irrefutable. The probability of excluding the falsely accused has steadily increased over the years as new methods are developed. Conventional ABO blood typing, for example, has a probability of exclusion (PE) of only 17%. This value increases to 53% with the inclusion of the Rh and MN systems. Additional serological markers can provide a probability of exclusion of greater than 99%. Today, the current method of choice for human identification is the polymerase chain reaction for the amplification of short tandem repeat (STR) multiplexes. This paper discusses the implications of nonpaternity in reverse paternity testing when only paternal DNA is available.  相似文献

The recent decline, indeed perhaps dismantling, of managed care is sometimes treated as both consequence and cause of the political reempowerment of medical providers, whose professional dominance managed care had challenged. Drawing evidence from Round III of the Community Tracking Study of the Center for Studying Health System Change, this article reviews the politics of four "arenas" of managed care regulation--prompt payment, mandated benefits, external appeals, and financial solvency--and concludes that the power of providers is contingent on patterns of coalition and conflict that differ across the discrete arenas. The zero-sum connotations of the "de" and "re" empowerment of providers under managed care fail to capture the subtlety of providers' search for fresh cultural, economic, and political resources in shifting policy contexts.  相似文献

If male workers categorize different groups of women coworkers and, subsequently, treat them differently, the experiences of women from one of these groups would not be indicative of the experiences of women from another group. When this different treatment involves hostile environment sexual harassment of one group, but not the other, then the law must recognize the possibility of "selective sexual harassment." Without this understanding of the nuances of the workplace dynamics, a court could mistake the women of the unharassed group as representing "reasonable women" and the women of the harassed group as simply oversensitive. This paper draws on empirical data to demonstrate such a situation and advocates for a version of the "reasonable victim" standard to facilitate a closer analysis of hostile environment sexual harassment suits.  相似文献
