My brand new bicycle had been stolen! Disbelief. Anger! Disappointment... I had been riding it for only a day,and was as excited as a,well,a boy with a new bike. Even though I only paid what would be the equivalent of half a tank of gas for my truck back home,I was still sorely put out. 相似文献

As a best-selling writer of popular romances during the first half of the twentieth century, Berta Ruck (1878-1978) has been characterised as a producer of 'omelettes of frivolity and sweetness' whose appeal was confined to adolescent girls and the servant classes. Closer attention to some of the early novels and to her own evaluation of her work, however, reveals her attempts to confront and articulate the impact of societal change upon a generation whose world was being irrevocably altered by the Great War and its aftermath. Her almost forensic attention to local detail and her treatment of contemporary questions of gender identity make her a compelling chronicler of the period and lend credibility to her claims of a broader readership than that generally associated with the genre. 相似文献

The present study examined the longitudinal links between perceptions of family connectedness and body satisfaction in 1,774
(52% female) adolescents. Participants (10–15 years of age at Time 1) completed self-report measures at three measurement
occasions separated by 1 year each. Mean group difference results showed that both body satisfaction levels and perceived
levels of family connectedness decreased over 2 years for the whole sample. As expected, girls were generally less satisfied
with their bodies than boys, particularly in the older cohort. Structural equation modelling was used to assess stability
coefficients and cross-lagged effects, and longitudinal bidirectional effects between perceptions of family connectedness
and body satisfaction were found for girls, but not for boys. This result suggests that adolescent girls’ body satisfaction
is both affected by and a predictor of perceived family connectedness. 相似文献

苏联解体20年后,几乎所有的前共产主义国家都程度不同地完成了从计划经济向市场经济的转型.然而,仍然有些转型国家在这一进程中落在后面,其中就有前苏联的5个中亚加盟共和国.对于这些既不同于俄罗斯和东欧,更不同于西方发达国家的国家来说,实现转型没有明显的参照模式.本文的目的就是分析在东亚地区取得成功的"发展型政权"是否也能够为中亚经济体的发展提供一个参考模式. 相似文献

Previous studies have indicated homophily in depressive symptoms among adolescent friends, resulting from both peer selection
and socialization processes. However, developmental differences and the role of school transitions in these processes have
not been elucidated. A sample of 367 (51% female) adolescents was followed from 6th to 11th grade to investigate prospective
relationships between adolescents’ and their friends’ depressive symptoms in middle school and in high school. Results revealed
that students selected friends with similar levels of depressive symptoms after each school transition. Additionally, friends
appeared to socialize adolescents to become more similar in depressive affect in late middle school years. These findings
suggest normative selection effects after school transitions, followed by socialization effects in middle school, but not
high school. 相似文献

This study examined the mediated and moderated effects of a universal family-focused preventive intervention, delivered during young adolescence, on internalizing symptoms assessed in young adulthood. Sixth grade students (N=446; 52% female; 98% White) and their families from 22 rural Midwestern school districts were randomly assigned to the experimental conditions in 1993. Self-report questionnaires were administered at seven time points (pre-test to young adulthood-age 21) to those receiving the Iowa Strengthening Families Program (ISFP) and to the control group. Results showed that growth factors of adolescent internalizing symptoms (grades 6-12) were predicted by ISFP condition and risk status (defined as early substance initiation). Moderation of the condition effect by risk status was found, with higher-risk adolescents benefitting more from the ISFP. Results also supported the hypothesis that the ISFP's effect on internalizing symptoms in young adulthood was mediated through growth factors of adolescents' internalizing symptoms; risk moderation, however, was only marginally significant in young adulthood. The relative reduction rate on clinical or subclinical levels of young adult internalizing symptoms was 28%, indicating that for every 100 young adults displaying clinical or subclinical levels of internalizing symptoms from school districts not offering an intervention, there could be as few as 72 displaying those levels of symptoms in school districts that offered middle school prevention programming. These findings highlight how the positive effects of family-focused universal interventions can extend to non-targeted outcomes and the related potential public-health impact of scaling up these interventions. 相似文献

Studies on homophobia among adolescents routinely depart from the assumption that this attitude will be continued into adulthood. However, little research has been conducted on how the transition toward adulthood actually affects homophobia. While earlier studies relied on cross-sectional observations, the present analysis makes use of the Belgian Political Panel Survey (2008-2011), tracking 2,815 respondents (52?% female, 48?% male) between the ages of 18 and 21. A conditional change model shows that while men had substantially higher levels of homophobia than women to begin with, this difference grew even larger throughout the observation period. The discrepancy between Muslim respondents and those with other religions became larger as well. Overall, the gender and religious differences already present in adolescence had become further polarized at the end of the observation period. Friendship relations with persons with a different sexual orientation, on the other hand, significantly reduced prejudice, especially among men, while the results also show that changes in the level of homophobia are related strongly to conservative views on gender roles. We conclude that groups that already display high levels of homophobia during adolescence are likely to grow even more extreme in their views in the transition to adulthood. 相似文献

According to Gottfredson and Hirschi??s self-control theory, child and adolescent variation in self-control results primarily from variations in parental socialization. Although much research reveals a link between parenting and self-control, many recent studies indicate that the etiology of self-control is more complex than what has been theoretically specified. In further considering this issue, the current study first presents a theoretical model that emphasizes the role that peers may play in the development of self-control, even when accounting for the influence of parents. Next, we empirically assess the extent to which peer behavior influences self-control during childhood. The data come from a sample of U.S. families (n?=?776); 48% of the subjects are male, their age was 9?years, and non-Hispanic whites represented 84% of the sample. The analysis revealed that peer behavior is significantly associated with subsequent self-control, even after accounting for differences in parental socialization, prior self-control, and other potential sources of spuriousness. The implications of the findings for theory and future research are discussed. 相似文献
