The aim of environmental monitoring programs is to provide information useful in enforcing existing environmental statutes and helping to detect and prevent future problems. Despite the considerable number of monitoring programs being conducted, information on the quality of the nation's environment remains poor and of little use in supporting environmental policymaking. This paper examines the role evaluation has played in developing an effective nationwide environmental monitoring system. Background information on environmental monitoring programs is provided, followed by a discussion of the evaluations of past programs and recommendations made for improvement. One program in particular, the "Status and Trends" program administered by the National Oceanic and ATmospheric Administration, is examined to explore whether environmental monitoring demonstrates a case of learning through evaluation. "Status and Trends" is based on the experience gained during several of the previous monitoring programs and incorporates many of the recommendations spawned from earlier environmental programs. Whether the program demonstrates a case of learning through evaluation will depend on the ability of the program to evolve as we learn more about environmental quality and out ability to measure it. 相似文献

In 2000 the Department of Mental Health of the World Health Organization (WHO) published a guide named Preventing Suicide. A Resource for Prison Officers as part of the WHO worldwide initiative for the prevention of suicide. In 2007 there are new epidemiological data on prison suicide, a more detailed discussion of risk factors accounting for the generally higher rate of suicide in correctional settings in comparison to the general population, and several strategies for developing screening instruments. As a first step, this paper presents an update of the WHO guide by the Task Force on Suicide in Prisons, created by the International Association for Suicide Prevention. A second paper, by the same Task Force, will present some international comparisons of suicide prevention services in correctional facilities. 相似文献

Peer relationships undergo dramatic shifts in form and function during adolescence, at the same time the incidence of socially evaluative fears sharply rises. Despite well-established links between social anxiety and broader interpersonal functioning, there is a dearth of research evaluating the impact of social anxiety on functioning in close relationships during this developmental stage. The present study examines the impact of social anxiety on functioning in close friendships and romantic relationships during adolescence. From a developmental psychopathology perspective, it was expected that social anxiety would influence functioning (quality, length, satisfaction) in romantic relationships through its influence on functioning in same- and other-sex friendships. Participants included 314 adolescents (60.5 % female, 14–19 years of age) with a prior or current history of romantic relationship involvement. Structural equation modeling was used to test a mediation model positing an indirect pathway from social anxiety to romantic relationship functioning through functioning in close same- and other-sex friendships. Given known gender differences in social anxiety and relationship functioning, gender also was explored as a potential moderator. Results supported the hypothesized indirect pathway whereby social anxiety was associated with impairment in same-sex friendships; functioning in same-sex friendships was associated with functioning in other-sex friendships, which was associated, in turn, with functioning in romantic relationships. While the hypothesized indirect pathway was significant among both boys and girls, there was greater continuity of functioning between same- and other-sex friendships for girls. These findings highlight the importance of examining the multiple downstream effects of social anxiety on perceived social functioning in adolescence, and suggest that continuity may exist for maladaptive patterns of socialization, particularly across developmentally salient close relationships. 相似文献

Documenting Louisiana Sugar (http://www.sussex.ac.uk/louisianasugar), an on-line database project rolled out in July 2008 and now freely available, provides historians and social scientists with an innovative tool for examining one sector of the plantation economy and agrarian society in the American South. Utilizing exceptionally detailed annual crop returns and additional census records, the project makes available two fully searchable databases that allow users to examine in micro and macro detail the evolution of one of America's definitive plantation crops, namely cane sugar. These are available on the project's website, which also includes census material, illustrations, bibliographies, and essays. What follows is a report describing the evolution and aims of this innovative effort to make primary sources widely available in digitized form on the internet. 相似文献

Previous research on the association between violence and biological stress regulation has been largely cross-sectional, and has also focused on childhood. Using longitudinal data from a low-income, high-risk, predominantly African-American sample (n = 266; 57 % female), we tested hypotheses about the influence of cumulative exposure to violence during adolescence and early adulthood on cortisol responses in early adulthood. We found that cumulative exposure to violence predicted an attenuated cortisol response. Further, we tested whether sex, mothers’ support, or fathers’ support moderated the effect of exposure to violence on cortisol responses. We found that the effect of cumulative exposure to violence on cortisol was modified by sex; specifically, males exposed to violence exhibited a more attenuated response pattern. In addition, the effect of cumulative exposure to violence on cortisol was moderated by the presence of fathers’ support during adolescence. The findings contribute to a better understanding of how cumulative exposure to violence influences biological outcomes, emphasizing the need to understand sex and parental support as moderators of risk. 相似文献
