Youth, identity, and homosexuality: the changing shape of sexual life in contemporary Brazil

This essay examines the relationship between homosexuality and adolescence in contemporary Brazil, focusing on a distinction between two rather different systems of sexual meanings that have structured the experience of same-sex relations: a traditional model of the sexual universe that continues to dominate sexual life in rural areas, and a more modern set of notions that has become increasingly important in the cities. It examines the ways in which these rather different systems have affected the experience of same-sex desires and practices during youth or adolescence, and suggests some of the ways in which the emergence of a gay subculture in urban Brazil has transformed the range of sexual possibilities and choices currently available to young men and women.     

A Dynamic Model of Racial Competition, Racial Inequality, and Interracial Violence

Race relations and stratification literatures offer explicit expectations concerning interracial conflict. Causal arguments derived from these perspectives are examined in this study to explore their ability to explain interracial violence above and beyond criminological perspectives of economic deprivation and racial inequality. The vast majority of previous aggregate-level studies on violence are cross-sectional, ignoring the importance of a dynamic model that incorporates the influence of changing structural conditions in urban areas on interracial violence. We explore theories that incorporate dynamic explanations for the influence of structural factors related to crime as well as racial conflict and employ a methodological approach that models the change in structural conditions for rare events such as interracial homicide. We find that changes between 1980 and 1990 in urban Black and Hispanic population composition, racial competition and racial inequality differentially explain the variation in White and Black interracial homicide offending.     

Correlates of physical activity in a community sample of older adults in Appalachia

Although much has been learned about the global determinants of physical activity in adults, there has been a lack of specific focus on gender, age, and urban/rural differences. In this church-based community sample of Appalachian adults (N = 1,239), the primary correlates of physical activity included age, gender, obesity, and self-efficacy. Overall, 42% of all participants and 31% of adults age 65 years or older met recommended guidelines for physical activity, which suggests that most participants do not engage in adequate levels of physical activity. Of participants who met physical activity guidelines, the most common modes of moderate and vigorous activity were walking briskly or uphill, heavy housework or gardening, light strength training, and biking. These particular activities that focus on building self-efficacy might be viable targets for intervention among older adults in rural communities.

Persistent Risk-Related Worry as a Function of Recalled Exposure to the Deepwater Horizon Oil Spill and Prior Trauma

Large oil spills are disasters associated with psychological effects for exposed communities. The amount of worry that individuals experience after a disaster may be influenced by many factors, such as the type and extent of exposure to disaster impacts, prior trauma, and sociodemographic characteristics. This study examined the nature and predictors of worry about ongoing impacts of the 2010 Deepwater Horizon (DH) oil spill reported by Gulf of Mexico coastal residents. A random sample of 2,520 adult residents of Gulf of Mexico coastal counties were administered a telephone survey in 2016, including items about persistent worry and exposure to DH impacts, prior trauma, residence at the time of the spill, and sociodemographic characteristics. Respondents varied in the amount of worry they reported about ongoing health, social, and economic impacts. Controlling for sociodemographic characteristics, higher exposure to the DH oil spill was related to higher levels of worry about ongoing impacts, with past traumatic events related specifically to worry about health impacts. Unexpectedly, those who moved into the region after the spill showed similar levels of worry to residents exposed to the spill, and higher levels than residents who did not recall being exposed to the DH oil spill. This study highlights the impact of the DH oil spill on coastal residents many years after the DH disaster. The findings underscore the need to examine multiple pathways by which individuals experience disasters and for risk researchers to close knowledge gaps about long-term impacts of oil spills within a multi-dimensional framework.
