The concluding article of this issue devoted to community involvement considers the unique perspective offered by each article on this topic in this issue, yet does so in the context of the commonalities among them. Most important of these commonalities, perhaps, is that all of the articles address, to some degree, the question of how adults can best be socialized to develop a habit of community participation. Some articles consider this question of encouraging community involvement in educational settings, while others consider the question in more general settings. Some articles focus on key conceptual processes, whereas others concentrate on practical issues in promoting involvement. Finally, virtually all of the articles consider the benefits of community involvement; some of the articles also explore the downside to efforts to promote community involvement.  相似文献

In male F344 rats exposed in a chronic inhalation study to methyl tertiary butyl ether (MTBE) a treatment related increase in severity of chronic nephropathy and mortality and an increase in hyaline droplets in the kidney were noted. Liver weights were increased in both rats and mice but no histological lesions other than hypertrophy are seen. Transient CNS effects but no indications of permanent nervous system effects were noted. MTBE is not a reproductive or developmental hazard. MTBE is rapidly absorbed. MTBE with some metabolite, tertiary butyl alcohol (TBA) and a little CO2, are excreted in the air. The urinary excretion products in animals are TBA metabolites, while in humans the urinary excretion products are MTBE and TBA. A comparison of the systemic responses of the possible metabolites TBA and formaldehyde indicate that they are not responsible for toxicity associated with MTBE, except that TBA may be partially responsible for the kidney effects reported. Animals and humans are similar in the uptake and excretion though with some differences in metabolism of MTBE. This supports the use of the animal data as a surrogate for humans.  相似文献

Nationally, the United States has a higher rate of teen pregnancy than any other industrialized nation. Native American youth have a higher birth rate than the national rate. A full-year healthy relationship program, based on Native American teachings, traditions, and cultural norms, was delivered to all eighth-grade students at a rural tribal school and a new group of eighth graders every year for 5 years, to teach healthy relationships and encourage abstinence. This article summarizes the Discovery Dating curriculum and compares the participants in the healthy relationship program to the comparison group, at the end of 5 years, in regards of the number of pregnancies as well as self-reported sexual behavior. The comparison group comprises students in the same community who attended a public middle school, rather than the tribal middle school, but the same public high school. All students had a similar age, socioeconomic status, culture, and ethnicity. Students who received the healthy relationship program (treatment group) had fewer pregnancies than the students who did not receive the healthy relationship program (comparison group). Of those who reported that they were sexually active, the students who received the healthy relationship program (treatment group) reported higher condom use than the students who did not receive the healthy relationship program (comparison group).  相似文献

This article discusses gender mainstreaming (GMS) as a strategy to implement gender equality in public work organizations by analysing discourse in terms of the theoretical notions of translation and circulation in organizations to shed light on how gender equality and the mainstreaming strategy are formulated in the documents which govern the Swedish fire and rescue services. More specifically, it looks at how the goals regarding gender equality are circulated and translated. The results show that gender equality as a practice is created in the translation of national goals in terms of the local context and its specific gender equality challenges. Furthermore, the article discusses how vague formulations in the documents are stabilized through circulation between the government and the public agency in question. The results indicate the central role played by maintaining stable translations over time and the presence of a double logic of change in the processes, as well as the importance of legitimizing gender equality initiatives.  相似文献

A psychological strategy for understanding the motivational underpinnings of volunteerism is described. In a presentation that merges the theoretical interests of researchers with the practical interests of volunteer administrators, six different motivational functions served by volunteerism are identified, and an inventory designed to measure these motivations is presented. The implications of this functional approach for the recruitment, placement, and retention of volunteers are then elaborated. Finally, recommendations are provided for volunteer administrators who seek to increase the number of people who volunteer and to improve their human resource management.  相似文献
