Studies have evaluated the outcomes of sexual harassment training, but considerably less research has focused on variables that influence sexual harassment training effectiveness. To address this need, we developed and tested a model of individual and contextual inhibitors of sexual harassment training motivation to learn. Survey data collected from male and female participants across three time points were used to test the mediating role of pessimism about sexual harassment change in the relationship between sexual harassment myth endorsement and motivation to learn, as well as the moderating role of organizational tolerance for sexual harassment on the relation between sexual harassment myth endorsement and pessimism. Results were consistent with the hypotheses, and exploratory analyses also revealed unhypothesized sex differences. The strengths and limitations of the study, implications for practitioners, and directions for future research are discussed.

Objective-This study characterizes physiological measures of heat exposure among US underground miners.Methods-Core body temperature measured by using ingestible sensors during subjects' normal work shifts was categorized into four temperature zones: less than 37.5 °C, 37.5 °C to less than 38 °C, 38 °C to less than 38.5 °C, and more than or equal to 38.5 °C.Results-On average, subjects changed temperature zones 13.8 times per shift. Temperatures increased above the recommended limit of 38 °C nearly 5 times per shift for an average of 26minutes each episode.Conclusions-Unlike previous heat stress research that reported only maximum and mean temperature measurements, this analysis demonstrates a dynamic pattern of physiologic heat strain, with core body temperatures changing frequently and exceeding the 38 °C limit multiple times per shift. Further research is needed on the impact of multiple short-term, intermittent heat exposures on miners. Keywords core body temperature; heat stress; mining Heat stress is a growing issue in US mining. Heat stress, which refers to the total heat load placed on the body, can lead to heat strain, which is the physiologic effect of heat exposure. Because of increasing mineral consumption worldwide and the use of new technologies, underground mines are expanding to greater depths; globally, coal and metal mines have reached depths of 1500 and 4500 m, respectively. 1 As mines expand to deeper, hotter levels, the risk of heat strain and subsequent heat-related illness among miners will likely increase. Differences in heat exhaustion incidence by depth of mine have been reported.

We proposed that civility norms would strengthen relationships between management commitment to safety and workers' safety motivation, safety behaviors, and injuries. Survey data were obtained from working adults in hazardous jobs-those for which physical labor is required and/or a realistic possibility of physical injury is present (N = 290). Results showed that management commitment positively related to workers' safety motivation, safety participation, and safety compliance, and negatively related to minor injuries. Furthermore, management commitment to safety displayed a stronger positive relationship with safety motivation and safety participation, and a stronger negative relationship with minor worker injuries when civility norms were high (versus low). The results confirm existing known relationships between management commitment to safety and worker safety motivation and behavior; furthermore, civility norms facilitate the relationships between management commitment to safety and various outcomes important to worker safety. In order to promote an optimally safe working environment, managers should demonstrate a commitment to worker safety and promote positive norms for interpersonal treatment between workers in their units.

Background Though mining remains a vital shiftwork industry for U.S. commerce, problems of continued prevalence of mineworker fatigue and its mitigation persist. Publications and reports on fatigue in mining appear to be rich and diverse, yet variable and remote, much like the industry itself. Methods The authors engaged in a brief nonexhaustive overview of the literature on sleep and fatigue among mineworking populations. Results This overview covers: potential sources of fatigue unique to mine work (e.g., monotonous and disengaging Work Tasks, underground environments and light exposure, remote work operations); evaluation of mitigation strategies for mineworker fatigue or working hours (e.g., shift‐scheduling and training); and areas for future research and practice (e.g., fatigue risk management systems in mining, mineworker sleep and fatigue surveillance, lighting interventions, and automation). Conclusions Fatigue continues to be a critical challenge for the mining industry. While research on the problems and solutions of mineworker fatigue has been limited to date, the future of fatigue research in mining can expand these findings by exploring the origins, nature, and outcomes of fatigue using advancements in lighting, automation, and fatigue risk management.
