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

Relationship schemas are core elements of personality that guide interpersonal functioning. The aim of this study is to examine stability and change in relationship schemas across two developmental epochs—adolescence and young adulthood—in the stories that people tell about their interactions with others. Using the Core Conflictual Relationship Theme Method, relationship themes were coded from semistructured interviews conducted in adolescence and again at age 25. The sample consisted of 40 participants in a longitudinal study of adolescent and young adult psychological development. There was considerable stability in the frequency with which particular themes were expressed in the narratives of adolescents and young adults. Significant changes from adolescence to young adulthood included a decrease in the perception of others as rejecting and of the self as opposing others. Young adults saw themselves and others more positively, and used a broader repertoire of themes in their relationship narratives than they had as adolescents. The basic continuity and particular changes in relationship schemas found in this study are consistent with knowledge about the adolescent-to-young-adult transition derived from other empirical and clinical findings. Relationship schemas may be rich units of study for learning about the development of interpersonal functioning.  相似文献

Previous studies have used probit or logit models to analyze two states of monetary policy (tighter or looser). In this paper we employ multinominal logit to permit Federal Reserve monetary policy to assume one of three alternative states (tighter, looser, or no change) as a function of three independent economic variables (unemployment, real growth, and inflation) and the amount of experience of the Board of Governors. The results indicate that the Federal Reserve reacted differently under Burns, Miller and Volcker and between Volcker's two operating procedures in the formulation of monetary policy.  相似文献

A laboratory study interested in the analysis of human hair for drugs-of-abuse was conducted to determine if drugs could be detected and quantified from hair. Supercritical fluid extraction (SFE) techniques followed by GC-MS analysis were applied to extract amphetamines from hair. The group of amphetamines included methylenedioxyamphetamine (MDA), methylenedioxymetamphetamine (MDMA), methylenedioxyethylamphetamine (MDEA) and internal standard mephentermine (MP). To validate information on amphetamine use in hair, powdered hair samples free from drugs were collected and soaked in a known amphetamine standard solution. Authentic fortified case hair samples taken from known drug users known to have consumed amphetamines were also analyzed for amphetamine. Results from this study show that amphetamine use can be detected in spiked and authentic fortified human hair using SFE techniques for qualitative and quantitative reproducible results.  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
