Hierarchical regression analyses were used to identify factors that functioned as either promotive or protective factors against
the impact of ecological risk on the psychological adjustment of 112 African American and 94 European American adolescents
(13–19 years of age). Indicators of ecological risk, promotive/protective factors, and adjustment were assessed concurrently
via adolescent self-report questionnaires. Supportive parenting emerged as a promotive factor for both African American and
European American adolescents for academic achievement, competence, and problem behaviors. Additionally, school connectedness
served as a promotive factor for both African American and European American adolescents with competence as the criterion.
However, in analyses with problem behaviors as the criterion, school connectedness intensified the effect of ecological risk
for European American adolescents. Of the three hypothesized positive factors (supportive parenting, ethnic identity, and
school connectedness), only ethnic identity emerged as a protective factor for problem behaviors and this effect was only
observed for European American adolescents.

The roles of age, social intelligence and parent-child communication in moderating the association between digital game playing and direct and indirect aggression were examined in 478 Finnish 10- and 13-year-old schoolchildren based on self-reports. The results confirmed that digital game violence was directly associated with direct aggression, especially at age 10, but only among boys. The moderating role of social intelligence was substantiated among older boys: game violence was associated with indirect aggression among those with high level of social intelligence. Further, as hypothesized, digital game playing was associated with direct aggression especially when parent-child communication was poor, but only among boys. Our findings emphasize the importance of individual and situational factors as moderators of the link between game violence and aggression. 相似文献

Stigma as a barrier to employment: mental disability and the Americans with Disabilities Act 总被引:1,自引:0,他引:1
Scheid TL 《International journal of law and psychiatry》2005,28(6):670-690
In a controversial expansion of workplace civil rights, the 1990 Americans with Disability Act (ADA) extended anti-discrimination protection to individuals with "mental impairments." One of the most critical barriers to the employment of individuals with mental disabilities is the degree of social stigma such disabilities incur, and there is compelling evidence that employers have stigmatizing attitudes and have discriminated against those with mental disabilities. This study examines the role played by stigma in employers' response to the 1990 Americans with Disability Act (ADA). A stratified sample of one hundred ninety employers were surveyed in 1996-1997 in a major Southern metropolitan area. Telephone interviews were completed with one hundred seventeen employers (response rate of 61.6%). The article describes employers' experiences with employees with mental disabilities and accommodations, specific employment practices, and attitudes towards those with mental disabilities. Stigma played an important role in conformity to the ADA (operationalized as either hiring or having specific recruiting policies for hiring individuals with mental disabilities). Furthermore, employers expressing coercive (fear of a lawsuit) as opposed to normative (belief that it is the right thing to do) rationales for compliance were more likely to hold stigmatized attitudes. Employers' beliefs about mental disability form a crucial foundation for truly supportive work environments (those that value difference and diversity), and further research is needed to determine if over time the ADA is successful in changing attitudes as well as behavior. 相似文献

美国是风险投资的起源地,风险投资在美国经济发展中起了不可忽视的作用,美国风险投资之所以成功,主要在于美国有适宜风险投资的"生态环境"。我国风险投资起步晚且发展相对缓慢,笔者认为,我们必须借鉴美国风险投资发展进程中成功的经验,结合我国实际设计促进风险投资健康发展的制度体系。 相似文献

美国对国际刑事法院的政策转变 总被引:1,自引:0,他引:1
卢有学 《山东警察学院学报》2004,16(4):24-30
美国对国际刑事法院的政策经历了从积极支持到极力反对的大转变。克林顿政府虽然积极参加法院规约的制订,但最终因为在管辖权、检察官独立启动调查起诉程序和侵略罪等问题上存在着重大分歧而投了反对票。布什政府则根据《美国军人保护法》采取了一系列极端敌视国际刑事法院的措施,其中尤以所谓的"第98条协定"为甚。但是,缔约国与美国签订的这种豁免协定实际上违背了规约的宗旨,与罗马规约第98条第2款不相符合,是非法的。 相似文献

和谐相邻关系是构建和谐社会的重要因素,其对青少年成长的作用是显而易见的,但青少年德育对相邻关系的关注是欠缺的。从相邻关系的法律性和道德性的角度而言,青少年德育应当重视相邻关系教育,加强青少年在相邻关系中的容忍、信任和道德两难教育,建议现行中小学德育教科书中充实相邻关系的内容。 相似文献

The relation between family functioning and school success was examined in 211 at risk, African American, inner city adolescents
attending middle school (grades 6–8). Interviews with adolescents and caregivers yielded data on family cohesion, parental
monitoring, and school engagement; school records provided data on grade point average. Results showed that both family cohesion
and parental monitoring predicted school engagement, but neither family characteristic predicted GPA. Important gender differences
also emerged. For boys only, the relation between family cohesion and school engagement was stronger when parental monitoring
was high. For girls only, the effects of cohesion and monitoring on school engagement were additive: girls with both high
family cohesion and high parental monitoring were most likely to be engaged in school. These findings extend the research
base on family protective factors for antisocial behavior in young adolescents. Implications for future examination of family
process characteristics in high-risk adolescents are discussed.

Cultural differences have been found in body image perceptions among Black and White adolescents, however little is known about the factors associated with perceptions of an ideal body size (IBS). This study examined differences in correlates of IBS among 265 Black (116 girls and 62 boys) and White (63 girls and 24 boys) adolescents. IBS for White girls and boys was related to perceptions of how their parents wanted them to look, while IBS for Black girls was related to perception of how peers look and would like to look. IBS for Black boys was significantly related to perceptions of their current size, how peers would like to look, how parents think they look, and depressive symptoms. Findings suggest cultural differences in the factors related to body image perceptions and have implications for educational programs promoting healthy body image development among Black and White adolescents.Assistant Professor, Department of Preventive Medicine and Public Health, University of Kansas Medical Center.
