The direct and mediated effects of socioenvironmental risk on internalizing and externalizing problems among Latino youth aged 10–14 were examined using prospective analyses. Participants in this study were 464 Latino mother and child dyads surveyed as part of the Welfare, Children & Families: A Three City Study. It was hypothesized that socioenvironmental risk (i.e., maternal psychological distress, maternal parenting stress, neighborhood disadvantage, and perceived financial strain) would influence later adolescent adjustment by interrupting important family processes and interfering with opportunities for adolescents to develop appropriate social competence. Using path analyses, the mediational model was compared across high and low acculturation groups. With two exceptions, the models for the high and low acculturation groups were equivalent. Results supported a mediated effect between early socioenvironmental risk and later adjustment problems for the low acculturation group through family routines and adolescent social competence. Among families high in acculturation, socioenvironmental risk effects were partially mediated through family routines and adolescent social competence. Finally, a path from gender to maternal monitoring was present in the low acculturation group model but not the high acculturation group model.

The transition to high school has been identified as a potentially difficult time in adolescents’ lives. Reductions in both academic and social functioning often accompany this transition. While these effects have been documented in urban youth, the move to high school has not been extensively studied in rural minority youth. Toward that end, the academic grades and substance use in ninth grade of 447 (184 male and 263 female) African-American adolescents from two rural counties in a state in the deep South were examined in relation to configurations of adaptation from sixth through eighth grade. Results indicate that individual with consistently positive patterns across middle school had higher grades and lower rates of substance use compared to individuals with persistent difficulties or those that transitioned to problem behavior. Many individuals who improved in their patterns of adaptation had relatively high grades, but also rather high rates of substance use in the ninth grade. David B.

This research examined the “mental health literacy” of adolescents concerning eating-disordered behavior. A vignette describing a fictional 16-year old female meeting diagnostic criteria for bulimia nervosa was presented to 522 female high school students, followed by a series of questions concerning treatment of and treatment-seeking for the problem described. Results indicated that primary care practitioners, mothers and close female friends were most highly regarded as potential sources of help. Self-help interventions, including the use of vitamins and minerals, were also highly regarded, whereas participants were less positive about the benefits of mental health specialists and ambivalent about the use of anti-depressant medication. Most participants believed that the problem described would be difficult to treat, and that relapse was likely even given appropriate treatment. An additional finding of note was that among participants with a high level of eating disorder symptoms (n=36, 6.9%), recognition of an eating problem was poor. We conclude that beliefs likely to be conducive to low and/or inappropriate treatment-seeking for eating problems may be common among adolescent girls. In addition, the findings suggest that prevention programs for the eating disorders need to target not only at-risk individuals, but also individuals in their immediate social environment.  相似文献

We examine the factors that improve the candidates’ likelihood of winning an election by drawing on information from campaign resources used by candidates running in the 2002 French parliamentary election. The main effects that we wish to analyze are the candidates’ gender, political affiliation and possible incumbency. We find that the contributions the candidates received and their political affiliations determine their acceding to the second round of the elections. But surprisingly once they make it to the second round, the contributions cease to be relevant; only the candidates’ gender, incumbency and the actual spending rather than the contribution levels matter.  相似文献

We use economic theory to examine the intensity of fundamentalist sects in which leaders work to enhance their followers’ observance level. We model three stylized situations under which fundamentalist groups function, examining the intensity of observance in each. We find that, under reasonable conditions, rivalry among fundamentalists makes them more extreme.  相似文献

A minimax procedure for electing committees   总被引:1,自引:0,他引:1  
A new voting procedure for electing committees, called the minimax procedure, is described. Based on approval balloting, it chooses the committee that minimizes the maximum Hamming distance to voters’ ballots, where these ballots are weighted by their proximity to other voters’ ballots. This minimax outcome may be diametrically opposed to the outcome obtained by aggregating approval votes in the usual manner, which minimizes the sum of the Hamming distances and is called the minisum outcome. The manipulability of these procedures, and their applicability when election outcomes are restricted in various ways, are also investigated. The minimax procedure is applied to the 2003 Game Theory Society election of a council of 12 new members from a list of 24 candidates. By rendering outlying voters less influential and not antagonizing any voters too much, it arguably would have produced a committee more representative of the interests of all voters than the minisum committee that was elected.  相似文献
