Correlates of Sustained Volunteering: Advocacy for Students with Disabilities

Parents of students with disabilities often receive support from special education advocates, who may be trained through a variety of programs. Using a web-based survey, this study examined the postgraduation advocacy activities of 83 graduates of one such volunteer advocacy training program. In the one to four years after program graduation, 63.8% (53 of 83) of the graduates advocated for one or more families; these sustained advocates reported stable rates of advocacy over time, and advocates performed activities that were either family-focused or school-focused. For graduates who advocated post-training, amounts of advocacy were positively related to satisfaction with advocating and with higher levels of involvement with other advocates and with the broader disability community. Compared to those not advocating after graduating, sustained advocates reported greater advocacy-role identities, increased involvement in disability groups, and higher likelihood to advocate in the upcoming year. Future research and practice implications are discussed.     

Does First Sex Really “Just Happen?” A Retrospective Exploratory Study of Sexual Debut Among American Adolescents

First sex marks a significant transition for most adolescents, yet teens often report that it was unplanned. Seventy-four college students participated in exploratory focus groups about their first sex. Although initially asked whether their first sex was spontaneous or planned, many participants revealed evidence of forethought or anticipation, signifying a third option, anticipation. This study suggests that the development and timing of sexual health messages should build on the apparent, albeit often unacknowledged, planning and thought that accompany the transition to first sex. Specifically, during the time immediately preceding first sex, young people might be particularly open to such messages.     

Soziale Integration durch Sport?

In this study the relationship between physical activity and different dimensions of social integration (number of friends, frequency of contact to friends, number of social contexts the individual is taking part in) is analysed using the data of the Partnermarktsurvey 2009. The concept of opportunities for interaction in foci of activity (here physical activity) is used as the theoretical framework. It can be shown that physical activity has an effect on the social integration of individuals: People who engage in physical activity have more friends, meet them more often and are integrated in more social contexts than people who are not physically active. Differences in social integration even exist among physically active people depending on the kind of sport activity and its form of organisation. Further the setting of the sport activity seems to be of importance. Finally it is recommended that longitudinal data used to investigate the exact causal effect of physical activity on social integration.     

Pink Ribbons Inc: breast cancer activism and the politics of philanthropy

This essay explores the cultural reconfiguration of breast cancer in the United States since the 1970s. It traces how breast cancer has been transformed in public discourse from a stigmatized disease best dealt with privately and in isolation, to a neglected epidemic worthy of public debate and political organizing, to an enriching and affirming experience during which women with the disease are rarely ‘patients’ and mostly ‘survivors.’ In the latter of these configurations, survivors emerge as symbols of hope who through their courage and vitality have elicited an outpouring of philanthropy, a continued supply of which will apparently ensure that the fight against breast cancer remains an unqualified success. By examining three key sites in this shift—federal policy, breast cancer marketing and the Susan G. Komen Foundation's Race for the Cure—the essay seeks to understand how, and with what effects, this transformation has occurred.
