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

What is the proper balance between legislative and judicial innovation and between formal and functional family recognition once legislatures have addressed gay men’s and lesbians’ families? In the civil-law jurisdiction of Quebec, legislative reforms allow two women to register as a child’s mothers. But judges have recognized a second mother ‘in fact’ by orders sharing custody where the parties had not used the new legislative channels. Such judicial creativity is reconcilable with the civil law and comparative scholars should flag it as a valuable resource. But it risks undermining legislative choices about family recognition. Perhaps the option to give a child a second mother includes the choice for a lesbian birth mother not to do so. Once two women become thinkable as spouses and mothers, judges risk inappropriately pressing a rich range of queer kinship possibilities into standard models.  相似文献

Councils of governments (COGS) have been subjected to powerful forces of change in the 1980s, due principally to drastic reductions in federal financial support. To survive, the councils have had to become more entrepreneural, to extend themselves in new directions They have scanned their local and regional task environments intensively for opportunities to form and/or join new networks and to provide more services in traditional and in new areas. The new style of council is described in this paper, using a market model. The model emphasizes opportunistic scanning of the regional task environment, and the assessment of issue networks as an iterative process in COG direction setting and implementation efforts.  相似文献
