Anxiety is prevalent in adolescents and may be particularly problematic in pregnant adolescents. The purpose of this structural equation modeling analysis was to test a biobehavioral model in which postpartum self‐competence mediated pathways from anxiety and cortisol during pregnancy to anxiety 3 years later. Self‐reports of anxiety and self‐competence and salivary cortisol samples were obtained from 78 healthy primiparous and 57 nonpregnant comparison adolescent girls matched for age and socioeconomic status. Assessments were done during the first half of pregnancy, 3–4 weeks after childbirth, and at a 3‐year follow up. For pregnant girls, linkages from initial anxiety to self‐competence to follow‐up anxiety were significant and negative, as hypothesized. Direct and indirect pathways between initial and follow‐up anxiety were significant. Cortisol levels did not predict self‐competence or anxiety. For nonpregnant adolescents, the model fit poorly. Findings suggest self‐competence may play a mediating role in young mothers' anxiety across time. 相似文献

The International Society for Third Sector Research (ISTR) celebrated its tenth anniversary in 2002. Voluntas, now the journal of ISTR, started publishing in 1990. This paper reviews changes in topics, diversity of regions studied, and diversity of authors from ISTR conference papers and Voluntas articles to examine the state of research on the third sector. The findings show that ISTR and Voluntas have increased in the range of content, regions covered, and disciplinary mix. The paper also reviews progress made on third sector research and some challenges that lie ahead. 相似文献

With the likelihood of future changes in climate and climate variability, it is important to understand how human systems may be vulnerable. Rural communities in Saskatchewan having agricultural-based economies are particularly dependent on climate and could be among the most vulnerable human systems in Canada. Future changes in climate are likely to have significant impacts on rural livelihoods, and rural populations will face the challenge of coping with climate change in light of a multitude of other changing socio-economic and environmental conditions. The Rural Municipality of Rudy No. 284 was chosen as a case study due to its access to irrigation, a key tool in climate adaptation for the agricultural system in the area against one of its most notorious climatic features - severe multi-year droughts. Further irrigation development would continue to reduce climate vulnerabilities. Even with irrigation however, the compounding effects of climate and other socio-economic changes will likely require modifications in current practices and policies in order to secure adequate livelihoods. Climate change adaptation in the RM must ensure equitable access to water and potentially irrigation, reduce barriers to collaboration when addressing communal problems, and provide more certainty in government programs. 相似文献

An analysis of the performance of five major review periodicals showed that School Library Journal and Booklist were most likely to have reviewed both a large percentage of total juvenile publication and those books singled out by the 1972–1974 and 1978–1980 Notable Children's Books Committees; the New York Times Book Review was least likely to have done so. There was a decline in coverage of the selected titles by the Bulletin of the Center for Children's Books. Even so, Bulletin and Horn Book, as well as Booklist and SLJ, continued to do a good job of calling attention to better books.Recent reviews appeared closer to the publication date of the book in question, with the time lag reduced in all but the New York Times, where it increased. Booklist's record of little more than a month was relatively impressive, with all other periodicals taking over two months or more, on the average. Each periodical showed tremendous internal inconsistency in promptness, however.The longest reviews, on the average, were published in NYTBR, the shortest in Bulletin. Recent reviews in SLJ and Booklist were longer than those found for the earlier sample.All but Horn Book reviews reflected increased critical attention in general. The practice of referring to other books and authors continued on a limited but definite scale for 1978–1980 titles. Attempts to predict readership were somewhat more likely to appear in the more recent issues of Booklist and Bulletin than earlier.The use of volunteer reviewers by School Library Journal resulted in a multiplicity of reviewers (25 people). Horn Book and NYTBR utilized eight people each. Booklist and Bulletin relied on reviews prepared by fulltime staffers.Opinions on general quality of the books examined continued to be basically consistent. 相似文献
