The peer context is a central focus in research on adolescent risk behaviors but few studies have investigated the role of the peer context in the perpetration of adolescent dating violence. This longitudinal study examined between-subjects and within-person contemporaneous and lagged effects of peer attributes, measured with social network analyses, on trajectories of dating violence perpetration and determined if effects varied by grade and/or sex of the adolescent. Data are from adolescents who participated in a five-wave panel study beginning when they were in 7 through 9th grade and ending when they were in 10 through 12th grade (n = 3,412); half were male, 40.5 % were white, 49.9 % were black and 10.4 % were of another race/ethnicity. Significant between-subjects effects indicate that adolescents who typically have friends who use dating violence, and girls who are typically high in social status, are at increased risk for using dating violence throughout adolescence. Adolescents who typically have high quality friendships and girls who typically have friends with pro-social beliefs are at decreased risk for using dating violence throughout adolescence. Significant within-person contemporaneous effects indicate that both boys and girls reported lower levels of dating violence than usual at times when they had more friends with pro-social beliefs, and reported higher levels of dating violence than usual at times when they had higher social status. None of the lagged effects were significant and none of the effects varied across grade. These findings suggest that the peer context plays an important role in the development of the perpetration of adolescent dating violence. 相似文献

General practitioners (GPs) are assumed to occupy an important position in the prevention of suicide through the introduction of risk assessment techniques commonly used in psychiatric practice. Despite this theoretical role for primary care services, it remains unclear how frequently GPs implement risk assessment in patients who may be vulnerable to suicide. To address this, a retrospective survey of probable suicides was conducted within a primary care setting utilizing a questionnaire of GPs who had experienced a patient suicide and was augmented by hospital and coroners' records. 85% of questionnaires were returned and 61 deaths were adjudged as suicides during the year long census period. 75% of suicides were male and 54% were aged under 35.28% were in contact with psychiatric services prior to death, although 60% had some diagnosis of mental disorder. GPs had little knowledge of a patient's life circumstances in up to half of cases. Recording of risk assessment occurred in 38% of subjects, was positively associated with prior psychiatric contact (p = 0.001) but negatively associated with presence of physical illness (p = 0.004), older patient age (p = 0.04), and GPs length in practice (p = 0.05). One GP felt their suicide case was preventable. The low rate of risk assessment and limited knowledge of patient lifestyle point to the need for active engagement of GPs in future suicide prevention strategies and should influence the content of training programs in primary care. 相似文献

Studies are reported on microbial conversion of various unsaturated fatty acids to 10-hydroxy and/or 10-oxo fatty acids by Micrococcus luteus. Four fatty acids possessing cis-9-unsaturation produced 10-hydroxy and 10-oxo fatty acid products, but three enoic acids possessing trans-9-unsaturation or double bond(s) in other than the 9-carbon position were inactive as substrates. 10-Hydroxy palmitic and stearic acids were converted to the corresponding 10-oxo fatty acids, but the 10-oxo compounds were inactive as substrates. This indicates that the metabolic sequence of cis-9-enoic fatty acid by the microbial enzyme(s) is first converted to 10-hydroxy fatty acid and then to its 10-oxo compound. 相似文献

This article argues for the importance of more focused scholarly attention on the development of mass‐elite linkages ‐ and in particular those linkages that transcend the electoral connection ‐ for understanding democratic consolidation, drawing on the post‐communist experience of the Czech Republic as a case study. Starting with the government's loss of its majority in the 1996 Czech elections amidst favourable economic conditions, we argue that this electoral result goes beyond the response to policy priorities to point to larger deficits in the development of channels of access and communication in the policy‐making process. Such deficits, characteristic of the post‐communist experience regionally, are not merely legacies of the stunted civil societies of the communist period, but also reflect a post‐communist style of governance that may itself discourage regularized citizen and associational input. As the episodic electoral connection alone cannot bear the weight of democratic consolidation, the risk is a pattern of mass‐elite linkages that creates a punctuated politics of elections and street demonstrations. 相似文献

Over the last decade, essentially since the Asian crisis of 1997–98, the economic integration of Northeast Asia has been marked by three overarching trends. Economic relations have become: 1) more institutionalized; 2) more “Asian;” and 3) more China-centric. These macro-trends are demonstrated and analyzed in the paper. But by way of anticipation, numerous counter-cutting facts need also to be kept in mind. In essence, recent trends, notable as they are, have by no means reversed three counter-realities: 1) economic ties are still largely driven, less by governments and formal arrangements, than by corporations in search of profits and production efficiencies; 2) despite growing economic interdependence across Northeast Asia and between that sub-region and Southeast Asia, Japan, China and South Korea remain heavily linked to global, and particularly US, markets; and 3) though China is an ever important hub in Northeast Asian trade and investment, Japan remains by far the most powerful economic player in the region. 相似文献
