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
Volatile organic compounds (VOCs) are by-products of cadaveric decomposition and are responsible for the odor associated with decomposing remains. The direct link between VOC production and individual postmortem microbes has not been well characterized experimentally. The purpose of this study was to profile VOCs released from three postmortem bacterial isolates (Bacillus subtilis, Ignatzschineria indica, I. ureiclastica) using solid-phase microextraction arrow (SPME Arrow) and gas chromatography–mass spectrometry (GC-MS). Species were inoculated in headspace vials on Standard Nutrient Agar and monitored over 5 days at 24°C. Each species exhibited a different VOC profile that included common decomposition VOCs. VOCs exhibited upward or downward temporal trends over time. Ignatzschineria indica produced a large amount of dimethyldisulfide. Other compounds of interest included alcohols, aldehydes, aromatics, and ketones. This provides foundational data to link decomposition odor with specific postmortem microbes to improve understanding of underlying mechanisms for decomposition VOC production. 相似文献
Delinquent behavior is common during adolescence and may disrupt trajectories of labor market attainment. Estimates of the relationship between delinquency and employment are threatened by selection bias, as youth who engage in delinquency often differ substantially from youth who do not. The current study examined the association between adolescents’ engagement in serious delinquency and four measures of occupational attainment in young adulthood: unemployment, personal earnings, employer-provided benefits, and occupational earnings. It examined the effect of delinquency independent of between-person differences in a variety of attributes and tested whether the hypothesized relationship was mediated by educational attainment, work experience, disconnectedness from both education and work, or criminal justice sanctioning. This study analyzed data from the first four waves of the National Longitudinal Survey of Adolescent to Adult Health (Add Health), yielding an analytic sample of 14,800 (51% female, mean age 16 years). The Wave 1 Add Health survey was administered in 1994–1995, and Wave 4 of the survey was administered in 2007–2008. The analytic strategy, propensity score weighting, produced estimates that were less biased by differences between youth who had and who had not engaged in delinquent behavior. The study found that delinquency was significantly associated with the likelihood of being unemployed: compared to non-delinquents, delinquents were more likely to be unemployed even after controlling for temporally prior traits and resources, human capital, and criminal justice contact. The results provided more qualified support for hypothesized relationships between delinquency and job quality. The study concluded that offending may result in less fruitful job searches, but once a search results in employment, employed delinquents are not readily discernible from employed non-delinquents in the quality of their jobs. These conclusions contribute to literature on the labor market outcomes of people with histories of adolescent delinquency as they enter young adulthood.
As transgender and gender-expansive (TGE) youth and young adults (YYA) navigate challenging environments, they often seek spaces for safety and acceptance. This study explores ways in which a group of TGE YYA who were engaged with a community-based service organization make sense of their experiences, challenges, and successes in ways that illuminate the factors and processes associated with resilience. Secondary data analysis was conducted on qualitative responses from 85 TGE YYA ages 13–24. The themes that emerged provide insight into the ways community-based programs and providers can understand and support the resilience of TGE YYA. 相似文献
Self-harm is widely recognized as a significant adolescent social problem, and recent research has begun to explore its etiology.
Drawing from Agnew’s (1992) social psychological strain theory of deviance, this study considers this issue by testing three hypotheses about the effects
of traditional and cyber bullying victimization on deliberate self-harm and suicidal ideation. The data come from a school-based
survey of adolescents in a rural county of a southeastern state (n = 426); 50% of subjects are female, their mean age was 15 years, and non-Hispanic whites represent 66% of the sample. The
analysis revealed that both types of bullying are positively related to self-harm and suicidal ideation, net of controls.
Moreover, those relationships are partially mediated by the negative emotions experienced by those who are bullied and partially
moderated by features of the adolescent’s social environment and self. Regarding the latter, exposure to authoritative parenting
and high self-control diminished the harmful effects of bullying victimization on self-harm and suicidal ideation. The article
concludes by discussing the implications of these conclusions for future research and for policy efforts designed to reduce
self-harm. 相似文献
