Mexican Origin Youths’ Trajectories of Perceived Peer Discrimination from Middle Childhood to Adolescence: Variation by Neighborhood Ethnic Concentration

Developmentally salient research on perceived peer discrimination among minority youths is limited. Little is known about trajectories of perceived peer discrimination across the developmental period ranging from middle childhood to adolescence. Ethically concentrated neighborhoods are hypothesized to protect minority youths from discrimination, but strong empirical tests are lacking. The first aim of the current study was to estimate trajectories of perceived peer discrimination from middle childhood to adolescence, as youths transitioned from elementary to middle and to high school. The second aim was to examine the relationship between neighborhood ethnic concentration and perceived peer discrimination over time. Using a diverse sample of 749 Mexican origin youths (48.9 % female), a series of growth models revealed that youths born in Mexico, relative to those born in the U.S., perceived higher discrimination in the 5th grade and decreases across time. Youths who had higher averages on neighborhood ethnic concentration (across the developmental period) experienced decreases in perceived peer discrimination over time; those that had lower average neighborhood ethnic concentration levels showed evidence of increasing trajectories. Further, when individuals experienced increases in their own neighborhood ethnic concentration levels (relative to their own cross-time averages), they reported lower levels of perceived peer discrimination. Neighborhood ethnic concentration findings were not explained by the concurrent changes youths were experiencing in school ethnic concentrations. The results support a culturally-informed developmental view of perceived peer discrimination that recognizes variability in co-ethnic neighborhood contexts. The results advance a view of ethnic enclaves as protective from mainstream threats.     

Resource Wealth,Democracy and Mobilisation

The impact of resource wealth on society remains highly contested in the literature. Some perspectives suggest that resource wealth is associated with political apathy, while others indicate that resource wealth fosters violent civil conflicts. We leverage these seemingly contradictory impacts of natural resources on society by expanding the scope of inquiry to explore different types of resource wealth (oil and minerals) as well as other dimensions of political life (protest). Utilising a global dataset for the period 1950–2006, we test the impact of resource wealth on mobilisation. We find that while oil wealth demobilises citizens in all regime types, mineral wealth strongly correlates with higher levels of mobilisation in democracies, though not in autocracies. In addition, using survey data, we examine individual-level attitudes toward protest participation in two resource-rich states, Peru and Ecuador. The results indicate that an individual living in a mineral-rich country like Peru is more likely to participate in a protest compared to an individual living in an oil-rich country like Ecuador. Our findings highlight the contributions of the resource activism framework for understanding the connection between natural resources and mobilisation.     

An empirical analysis of viewer demand for U.S. programming and the effect of Canadian broadcasting regulations

Using viewer share and rating points for the Toronto/Hamilton television market, we estimate the demand for U.S. programs retransmitted in Canada and test several hypotheses on the effect of domestic content regulation, program type, simulcasting regulations, network affiliation, and other broadcasting variables on audience size. These estimates have general implications for the current trade debate over the cultural industries. More specifically, our results provide support for some U.S. rights holders arguing for greater compensation for the retransmission of programs in Canada, and they raise questions about the publicly stated rationale of domestic content quotas generating net social benefits. These results can generalize to the many European Union and English-speaking countries using similar domestic content quotas.     

Intimate partner violence and miscarriage: examination of the role of physical and psychological abuse and posttraumatic stress disorder

Despite research documenting high rates of violence during pregnancy, few studies have examined the impact of physical abuse, psychological abuse, and posttraumatic stress disorder (PTSD) on miscarriage. Secondary analysis of data collected by the Chicago Women's Health Risk Study permitted an exploration of the relationships among physical abuse, psychological abuse, PTSD, and miscarriage among 118 primarily ethnic minority women. The interaction between maximum severity of abuse and age provided the best multivariate predictor of miscarriage rate, accounting for 26.9% of the variance between live birth and miscarriage outcome. Mean scores of psychological abuse, physical violence, forced sex, and PTSD were significantly higher in the miscarriage group than in the live birth group. Women who experience physical violence and psychological abuse during pregnancy may be at greater risk for miscarriage. Prospective studies can confirm findings and determine underlying mechanisms. Routine screening for traumatic stress and PTSD may reduce rates of miscarriage.     

The Believability of Hearsay Testimony in a Child Sexual Assault Trial

Two experiments investigated how mock jurors react to hearsay testimony in a case involving child sexual assault. Participants read a fictional criminal trial summary involving the sexual assault of a 4-(Experiment 2 only), 6-, or 14-year-old female. The summaries were presented in one of four conditions: (a) child condition—the alleged victim testified; (b) hearsay condition—the alleged victim did not testify, but an adult hearsay witness did testify; (c) multiple condition (Experiment 1 only)—both the alleged victim and the adult hearsay witness testified; and (d) no-witness condition—neither the alleged victim nor the hearsay witness testified. The hearsay testimony was believed to a considerable degree, and this testimony led to an increase in the perceived guilt of the defendant. Moreover, these results were comparable to those of conditions in which the alleged victim testified. The results are discussed in terms of the psychosocial factors affecting the perception of hearsay testimony in a child sexual assault trial.
