Acculturative stress, social support, and coping: relations to psychological adjustment among Mexican American college students

This study examined the relations between acculturative stress and psychological functioning, as well as the protective role of social support and coping style, in a sample of 148 Mexican American college students (67% female, 33% male; mean age = 23.05 years, SD = 3.33). In bivariate analyses, acculturative stress was associated with higher levels of anxiety and depressive symptoms. Moreover, active coping was associated with better adjustment (lower depression), whereas avoidant coping predicted poorer adjustment (higher levels of depression and anxiety). Tests of interaction effects indicated that parental support and active coping buffered the effects of high acculturative stress on anxiety symptoms and depressive symptoms. In addition, peer support moderated the relation between acculturative stress and anxiety symptoms. Implications for reducing the effects of acculturative stress among Mexican American college students are discussed.     

Between- or within-culture variation?: Culture group as a moderator of the relations between individual differences and resource allocation preferences

Recent theoretical discussion of the influence of between- and within-culture factors on social behaviors suggests that both approaches may be useful. The present study was designed to investigate the joint influence of sociocultural (between-group) and individual (within-group) factors on resource allocation preferences. Brazilian (n=166) and European–American (n=99) children with ages ranging from 37 to 140 months were administered a resource allocation task, which consisted of distributing rewards to themselves or to an acquaintance. As expected, individualistic resource allocation preferences decreased with age, whereas competitive and cooperative resource allocation preferences increased with age. Culture group, the task-specific cognitive demands, and the gender of the child, however, moderated these age differences. For example, gender differences in resource allocation preferences were stronger among Brazilians as compared to European–Americans and stronger in the reduced cognitive demand condition. Models of cooperative and competitive behaviors that consider the role of culture group, gender, and cognitive development and applied implications are discussed.     

The organisation of spatial and temporal relations in memory

Episodic memories are comprised of details of “where” and “when”; spatial and temporal relations, respectively. However, evidence from behavioural, neuropsychological, and neuroimaging studies has provided mixed interpretations about how memories for spatial and temporal relations are organised—they may be hierarchical, fully interactive, or independent. In the current study, we examined the interaction of memory for spatial and temporal relations. Using explicit reports and eye-tracking, we assessed younger and older adults’ memory for spatial and temporal relations of objects that were presented singly across time in unique spatial locations. Explicit change detection of spatial relations was affected by a change in temporal relations, but explicit change detection of temporal relations was not affected by a change in spatial relations. Younger and older adults showed eye movement evidence of incidental memory for temporal relations, but only younger adults showed eye movement evidence of incidental memory for spatial relations. Together, these findings point towards a hierarchical organisation of relational memory. The implications of these findings are discussed in the context of the neural mechanisms that may support such a hierarchical organisation of memory.     

An Empowerment Evaluation Model for Sexual Assault Programs: Empirical Evidence of Effectiveness

Using an empowerment evaluation approach, the Sexual Assault and Rape Prevention (SARP) Evaluation Project brought together university researchers, public health evaluators, state funders, and program staff to provide evaluation training and consultation to all state-funded rape prevention and victim services programs in Michigan. In this paper, the specific activities of the SARP project are described, and process and outcome data are presented that address the effectiveness of this empowerment evaluation approach. Based on subjective reports from program staff and objective data obtained from state funders, results suggest that this evaluation model was successful in helping 90% of the prevention programs and 75% of the victim services programs successfully develop and launch program evaluations. One-year follow-up data indicate that 90% of the programs had sustained their evaluation efforts after the formal work of the SARP project had ended.     

The Social Networks of Women Experiencing Domestic Violence

The research literature has demonstrated that battered women living in shelters experience impaired social support. This study examines this phenomenon among battered women living in the community. This study compared a group of pregnant battered women (n = 145) and a group of pregnant nonbattered women (n = 58) in terms of their structural [e.g., total number of supporters, network members in violent relationships with their partners (an index of homophily or nonhomophily) and functional (e.g., emotional)] social support. Four reasons for impaired support in battered women were proposed and examined, including social isolation, failure to disclose abuse, homophily, and low SES. Only homophily was related to impaired support among battered women. In addition, the relationship between structural and functional support and mental health outcomes (e.g., depression, self-esteem) was examined. Criticism, practical support, homophily, and disclosure were all significant predictors of mental health for battered women. Implications for community-based interventions are discussed in the context of current intervention strategies with battered women.     

On the ethics of facial transplantation research

Transplantation continues to push the frontiers of medicine into domains that summon forth troublesome ethical questions. Looming on the frontier today is human facial transplantation. We develop criteria that, we maintain, must be satisfied in order to ethically undertake this as-yet-untried transplant procedure. We draw on the criteria advanced by Dr. Francis Moore in the late 1980s for introducing innovative procedures in transplant surgery. In addition to these we also insist that human face transplantation must meet all the ethical requirements usually applied to health care research. We summarize the achievements of transplant surgery to date, focusing in particular on the safety and efficacy of immunosuppressive medications. We also emphasize the importance of risk/benefit assessments that take into account the physical, aesthetic, psychological, and social dimensions of facial disfiguration, reconstruction, and transplantation. Finally, we maintain that the time has come to move facial transplantation research into the clinical phase.     

Moving Beyond the Individual: Examining the Effects of Domestic Violence Policies on Social Norms

To be effective, criminal justice policies should affect the underlying social norms for which the policies were enacted. This study sought to determine whether public perceptions of criminal justice policies on domestic violence affected social norms. Two waves of data were collected via a telephone survey where a random probability sample of 973 residents was drawn from 4 communities. A structural equation model was tested and confirmed. Results provided strong support for the hypothesis that perceptions of criminal justice policies have direct effects on attitudes toward criminal justice response, and indirect effects on victim-blaming attitudes, both underlying social norms related to domestic violence. The enactment of criminal justice policies, therefore, may have an impact beyond victims and perpetrators and lead to a transformation of the community through the emergence of new social norms. Public awareness campaigns designed to disseminate criminal justice policies may be instrumental in provoking social change.     

Time-dependent modulation of inhibitory avoidance memory by spermidine in rats

The polyamines, spermine, spermidine, and putrescine, are a group of aliphatic amines that may act as physiological modulators of N-methyl-D-aspartate (NMDA) receptors. Although the modulatory role of polyamines in NMDA receptor function has long been known, the effects of polyamines on learning and memory only recently began to be unraveled. In the present study, we investigated the effect of bilateral infusions of spermidine (0.02-2 nmol), a polyamine agonist, into the CA1 region of the rat dorsal hippocampus on inhibitory avoidance learning 30 min pre-training, immediately post-training, 6 h post-training, or 10 min pre-test. Bilateral microinjections of 0.2 nmol spermidine prolonged step-down latencies compared to the respective control group when administered 30 min pre-training or immediately post-training. These results provide evidence that the modulatory effects of spermidine on the acquisition and/or early consolidation of memory of inhibitory avoidance tasks in the hippocampus occur within a limited time window.     

Environmental barriers to HIV prevention among incarcerated adolescents: a qualitative assessment

The purpose of this research was to identify environmental factors that influence incarcerated adolescents' risk for HIV/STDs. Based on data from six gender-stratified focus groups consisting of 28 incarcerated adolescents from three detention centers in Georgia, the following salient environments emerged: schools, families, peer groups, neighborhoods, malls, and detention centers. These environments represent places in which factors related to sexual decision-making are embedded for this high-risk population. Within these environments, five factors influence their risk for HIV/STDs: (1) hierarchical messages that promote abstinence and risk reduction, (2) availability and accessibility of condoms, (3) acceptability of condoms, (4) availability of comprehensive sex education, and (5) parental communication about sex and risk reduction. Increased understanding of the role of these factors may contribute to the development of integrated interventions designed to prevent HIV/STDs among incarcerated adolescents.     

The Influence of Community Violence on the Functioning of Women Experiencing Domestic Violence

The relationships among women’s experiences of domestic violence, community violence, and their mental health functioning were explored (N = 94). Social contagion theory was used to argue for the link between community violence and family violence. Results revealed that women’s experiences of domestic violence were not related to community violence. Furthermore, women’s mental health functioning was solely associated with their experiences of domestic violence, not with community violence. Results are discussed in terms of an ecological model of domestic violence and future directions for exploring linkages between neighborhood characteristics and individual experiences.
