Symmetric two-stage contests with budget constraints 总被引:1,自引:0,他引:1
The impact of a budget constraint on individual expenditures is examined in two models of two-stage contests with homogenous and risk-neutral players competing to win a single, indivisible, commonly valued rent. The set of players is partitioned into equally sized groups. In the first model, one contestant from each group survives to compete on the second stage against the other survivors. In the second model, one group survives the first stage and its members compete against each other on the second stage. We derive and discuss the symmetric subgame perfect equilibrium solution for each model. 相似文献

It is important to understand the epidemiology of intimate partner violence (IPV) experienced by both males and females. Data were drawn from the U.S. National Comorbidity Survey Replication. The relationships between physical IPV and child abuse, mental disorders, and suicidal ideation and attempts among males and females were examined. The results indicate that child sexual abuse was associated with IPV among males, whereas child physical and sexual abuse was associated with IPV among females. IPV was associated with poor mental health outcomes for males and females, although sex differences are noted. The sex differences indicate that females experience a wider range of poor mental health outcomes compared to males. Knowledge about correlates of IPV can be useful in identifying individuals exposed to violence. Further research is required to identify effective methods to reduce exposure to IPV and to adequately address the specific needs of male and female victims of IPV. 相似文献

The United States Sentencing Commission promulgated federal organizational sentencing guidelines in 1991. The final product
eroded the guidelines’ original severity, as drafts were rejected over a period of 4 years. The initial goal of the Commission
was to implement organizational guidelines that were on par with individual-level sanctions in order to remove any suggestion
that powerful corporations receive lesser penalties than individuals convicted of “street crimes”. This study analyzes the
erosion of the Commission’s stated goal by evaluating the organizational structures, individual and group characteristics,
and the social, political, economic, and historical contexts involved in the evolution of federal sentencing guidelines for
organizations. Results indicate that, while structural-level variables played a large part in explaining the development of
the guidelines, a more accurate and complete understanding of this process is possible by including an analysis of the individual-level
characteristics of Commissioners, including their professional backgrounds, ideological perspectives, styles of leadership,
and future goals.

Research on the academic adjustment of immigrant adolescents has been predominately conducted in large cities among established
migration areas. To broaden the field’s restricted focus, data from 172 (58% female) Asian American adolescents who reside
within a non-traditional or emerging immigrant community in the Southeastern US were used to examine gender differences in
academic adjustment as well as school, family, and cultural variables as potential mediators of gender differences found.
Results suggest that girls report significantly higher educational goals, intrinsic academic motivation, and utility value
of school compared to boys. These gender differences are statistically mediated by ethnic exploration and family processes,
most prominently, family respect. School connectedness and perceived discrimination are also associated with academic adjustment
at the bivariate level, suggesting that academic success may be best promoted if multiple domains of influence can be targeted. 相似文献

Runaway and homeless youth often have a constellation of background behavioral, emotional, and familial problems that contribute to stress and maladaptive behaviors, which, in turn, can lead to self-harming and suicidal behaviors. The current study examined the roles of stress and maladaptive behaviors as mediators between demographic and psychosocial background characteristics and self-injurious outcomes through the lens of the stress process paradigm. The model was tested in a sample of runaway and homeless youth from Los Angeles County (N = 474, age 12–24, 41 % female, 17 % White, 32.5 % African American, 21.5 % Hispanic/Latino). Background variables (gender, age, sexual minority status, parental drug use history, and emotional distress) predicted hypothesized mediators of maladaptive behaviors and recent stress. In turn, it was hypothesized that the mediators would predict self-harming behaviors and suicide attempts in the last 3 months. Females and LGBT (lesbian, gay, bisexual, transgender) youth were more likely to have self-harmed and attempted suicide; younger participants reported more self-harming. The mediating constructs were associated more highly with self-harming than suicide attempts bivariately, although differences were modest. Maladaptive behaviors and recent stress were significant predictors of self-harm, whereas only recent stress was a significant predictor of suicide attempts. All background factors were significant predictors of recent stress. Older age, a history of parental drug use, and greater emotional distress predicted problem drug use. Males, younger participants, and participants with emotional distress reported more delinquent behaviors. Significant indirect effects on self-harming behaviors were mediated through stress and maladaptive behaviors. The hypothesized paradigm was useful in explaining the associations among background factors and self-injurious outcomes and the influence of mediating factors on these associations. 相似文献
