The sex ratio and male-on-female intimate partner violence

Two divergent perspectives have been articulated in the literature regarding the effect that an unbalanced sex ratio is speculated to have on male-on-female intimate partner violence. Evolutionary psychology proffers that a high sex ratio (i.e., more men than women in the population) propagates competition among males for female mates. This competition for female mates is thought to engender sexual jealousy among men, which in turn results in male-on-female intimate partner violence. In contrast, the Guttentag and Secord thesis argues that a high sex ratio acts to attenuate rather than amplify male-on-female intimate partner violence because the relatively small number of women in the population makes them more highly valued and respected by men. Using data culled from the Federal Bureau of Investigation's National Incident-Based Reporting System (NIBRS) and the Census, we investigate the relationship between the sex ratio and male-on-female intimate partner violence. We define male-on-female intimate partner violence as violence occurring within a marriage or boyfriend/girlfriend type relationship. Multivariate regression results furnish evidence supporting evolutionary psychology by demonstrating that a high sex ratio increases male-on-female intimate partner violence. Results also show that male-on-female intimate partner violence is higher in cities where more women work. Such a finding further buttresses the logic associated with evolutionary psychology because participation in the workforce is theorized to afford a woman a greater opportunity to meet and interact with men other than her husband or boyfriend.     

Rational rejection? The ethical complications of assessing organ transplant candidates in the United Kingdom and the United States

The practice of allocating scarce organs in medicine is an ethical minefield. Due to the organ shortage, organ procurement agencies in both the United Kingdom and the United States are placed in the unenviable position of having to choose a limited number of patients to compete equally for life-saving treatment. They do this by composing multidisciplinary transplant teams, which must evaluate transplant candidates and their complex range of personal, medical, environmental, psychiatric and financial characteristics. During the candidate assessment process, such teams may often be torn between their moral duty to save those who are most in need, considerations of efficiency, and the battle against forming moral judgments about particular candidates. Several ethical approaches can be adopted by transplant teams during the decision-making process, but do these ideologies provide adequate justification for their sometimes controversial decisions? This article provides a detailed examination of the ethical principles available to transplant teams in the United Kingdom and the United States, and the effect that these principles have on assessment procedures, organ allocation protocols, transplant candidates and their prospects.     

Reciprocal Relationships between Trajectories of Depressive Symptoms and Screen Media Use during Adolescence

Adolescents are constantly connected with each other and the digital landscape through a myriad of screen media devices. Unprecedented access to the wider world and hence a variety of activities, particularly since the introduction of mobile technology, has given rise to questions regarding the impact of this changing media environment on the mental health of young people. Depressive symptoms are one of the most common disabling health issues in adolescence and although research has examined associations between screen use and symptoms of depression, longitudinal investigations are rare and fewer still consider trajectories of change in symptoms. Given the plethora of devices and normalisation of their use, understanding potential longitudinal associations with mental health is crucial. A sample of 1,749 (47% female) adolescents (10–17 years) participated in six waves of data collection over two years. Symptoms of depression, time spent on screens, and on separate screen activities (social networking, gaming, web browsing, TV/passive) were self-reported. Latent growth curve modelling revealed three trajectories of depressive symptoms (low-stable, high-decreasing, and low-increasing) and there were important differences across these groups on screen use. Some small, positive associations were evident between depressive symptoms and later screen use, and between screen use and later depressive symptoms. However, a Random Intercept Cross Lagged Panel Model revealed no consistent support for a longitudinal association. The study highlights the importance of considering differential trajectories of depressive symptoms and specific forms of screen activity to understand these relationships.     

Tracing policy influence of diffuse interests: the post-crisis consumer finance protection politics in the US

Dodd–Frank, the financial reform law passed in the United States in response to the 2008 financial crisis, established the Consumer Financial Protection Bureau, a new federal regulator with the sole responsibility of protecting consumers from unfair, deceptive, or abusive practices. This decision marked the end of a highly politicized reform debate in the US Congress, in which proponents of the new bureau would normally have been considered to be much weaker than its opponents. Paradoxically, an emerging civil society coalition successfully lobbied decision-makers and countered industry attempts to prevent industry capture. What explains the fact that rather weak and peripheral actors prevailed over more resourceful and dominant actors? The goal of this study is to examine and challenge questions of regulatory capture by concentrated industry interests in the reform debates in response to the credit crisis which originated in the US in 2007. The analysis suggests that for weak actors to prevail in policy conflicts over established, resource-rich opponents, they must undertake broad coalition building among themselves and with influential elite allies outside and inside of Congress who share the same policy goals.     

Meaning in Life as a Mediator of Ethnic Identity and Adjustment Among Adolescents from Latin,Asian, and European American Backgrounds

Establishing a sense of life meaning is a primary facet of well-being, yet is understudied in adolescent development. Using data from 579 adolescents (53% female) from Latin American, Asian, and European backgrounds, demographic differences in meaning in life, links with psychological and academic adjustment, and the role of meaning in explaining associations between ethnic identity and adjustment were examined. Although no generational or gender differences were found, Asian Americans reported higher search for meaning than Latin and European Americans. Presence of meaning was positively associated with self-esteem, academic adjustment, daily well-being, and ethnic belonging and exploration, whereas search for meaning was related to lower self-esteem and less stability in daily well-being. Presence of meaning mediated associations between ethnic identity and adjustment, explaining 28–52% of ethnic identity’s protective effect on development. Ethnic identity thus appears to affect adjustment, in part, through its role in fostering a positive sense of meaning in adolescents’ lives.     

The Influence of Maternal Acculturation,Neighborhood Disadvantage,and Parenting on Chinese American Adolescents’ Conduct Problems: Testing the Segmented Assimilation Hypothesis

Associations among neighborhood disadvantage, maternal acculturation, parenting and conduct problems were investigated in a sample of 444 Chinese American adolescents. Adolescents (54% female, 46% male) ranged from 12 to 15 years of age (mean age = 13.0 years). Multilevel modeling was employed to test the hypothesis that the association between maternal acculturation and adolescents’ conduct problems could be explained by differences in mothers’ reliance on monitoring and harsh discipline. In addition, guided by segmented assimilation theory, measures of neighborhood disadvantage were expected not only to be related to differences in parenting, but also to moderate the effects of maternal acculturation on parenting. Results indicated that increased maternal acculturation was related to higher levels of maternal monitoring and lower levels of harsh discipline, which, in turn, were related to lower levels of adolescents’ conduct problems. Hierarchical linear modeling results revealed that neighborhood disadvantage was related to lower levels of maternal monitoring. However, neighborhood disadvantage did not moderate the link between maternal acculturation and parenting practices.

Gendered Academic Adjustment among Asian American Adolescents in an Emerging Immigrant Community

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.     

Parent and Peer Pathways to Adolescent Delinquency: Variations by Ethnicity and Neighborhood Context

Effects of ethnicity and neighborhood quality often are confounded in research on adolescent delinquent behavior. This study examined the pathways to delinquency among 2,277 African American and 5,973 European American youth residing in high-risk and low-risk neighborhoods. Using data from a national study of youth, a meditational model was tested in which parenting practices (parental control and maternal support) were hypothesized to influence adolescents' participation in delinquent behavior through their affiliation with deviant peers. The relationships of family and neighborhood risk to parenting practices and deviant peer affiliation were also examined. Results of multi-group structural equation models provided support for the core meditational model in both ethnic groups, as well as evidence of a direct effect of maternal support on delinquency. When a similar model was tested within each ethnic group to compare youths residing in high-risk and low-risk neighborhoods, few neighborhood differences were found. The results indicate that, for both African American and European American youth, low parental control influences delinquency indirectly through its effect on deviant peer affiliation, whereas maternal support has both direct and indirect effects. However, the contextual factors influencing parenting practices and deviant peer affiliation appear to vary somewhat across ethnic groups. Overall the present study highlights the need to look at the joint influence of neighborhood context and ethnicity on adolescent problem behavior.
