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.     

Community exercise program for older adults recovering from hip fracture: a pilot study

Community-based rehabilitative exercise programs might be an effective means to improve functional outcomes for hip-fracture patients. The purpose of this study was to evaluate the effectiveness of a community exercise program (CEP) for older adults recovering from hip fracture. Twenty-five older adults (mean age 80.0 +/- 6.0 years; 24 women; 71 +/- 23 days post-hip fracture) participated in this pilot study (17 exercise, 8 control). The CEP involved functional stepping and lower extremity-strengthening exercises. Control participants received only standard outpatient therapy. Measures of functional mobility, balance confidence, falls efficacy, lower extremity strength, and daily physical activity were evaluated at baseline and at 16 weeks. Improvements for self-reported physical activity, mobility, balance, and knee-extensor strength were observed for the CEP group. This study demonstrated that a CEP is beneficial for community-dwelling older adults post-hip fracture.     

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.
