Occupational Safety and Health of Women in Mining.

The mining industry plays a critical role in the U.S. economy, with active mines in every state producing materials such as those used to construct houses and roads, make medicines, and manufacture cars and electronics. Throughout its history, mining has been a male-dominated industry. Recent estimates indicate that between 10% and 17% of miners are women. Previous occupational safety and health (OSH) research has focused primarily on the male experience. In more recent years, the mining industry has engaged in efforts to increase workforce diversity through the recruitment and retention of women miners. To meet the needs of a diverse workforce, it is critically important to identify OSH concerns that are unique to populations that have been understudied and to develop work-related policies and practices that improve their work experiences and health outcomes. The purpose of this article is to describe the specific OSH challenges women as miners face and to discuss how the National Institute for Occupational Safety and Health's (NIOSH) Mining Program is situated to address these challenges through its Mining Program Strategic Plan.

The impact of afterschool program attendance on academic outcomes of middle school students.

This evaluation examined the effects of afterschool programs-supported by an afterschool system intermediary organization (ASIO)-on middle school students' academic performance and examined how those effects varied by student characteristics and program engagement. In this longitudinal, quasi-experimental matched comparison group evaluation, propensity score matching was used to create demographically balanced samples of ASIO-supported afterschool program participants and nonparticipants. Students enrolled in the afterschool programs did not differ from non-participants in growth over time on most academic outcomes. Students attending the afterschool programs showed less growth on certain state test scores compared to nonparticipants. Student demographic characteristics did not consistently influence participant outcomes. Among program participants only, students who were enrolled more than 1 year demonstrated a 7-percentile-point increase in state test scores per year of program engagement. There was no consistent evidence that ASIO-supported afterschool program participation was associated with improved student academic outcomes. However, study results support increased emphasis on afterschool program retention, given that longer duration of participation in the afterschool programs was associated with more growth on multiple academic outcomes.
