James Griffith 《Suicide & life-threatening behavior》2019,49(1):41-53
Sexual harassment has been associated with suicidal behaviors, and with the rise in suicides in the U.S. military, sexual harassment's role in suicide has been of growing interest. Lacking are studies that examine group‐ or unit‐level variables in the relationship of sexual harassment to suicidal behaviors (thoughts, plans, and attempts). In this study, survey data from soldiers (12,567 soldiers in 180 company‐sized units) who completed the Unit Risk Inventory administered during calendar year 2010 were analyzed using hierarchical linear modeling. At the individual level, sexual harassment was associated with a fivefold increase for risk of suicide. Reporting that leaders could be trusted was associated with a decreased suicide risk by about one‐third. There was no statistically significant interaction between sexual harassment and trusted leaders in predicting the suicidal behaviors. At the group level, units or companies having higher levels of sexual harassment also had soldiers three times more at risk for suicide. A cross‐leveling effect was also observed: Among units having higher levels of sexual harassment, the negative correlation (buffering effect of unit leaders on suicidal behaviors) was diminished. Implications of findings for preventing sexual harassment and suicide risk are discussed. 相似文献

Restrictions in working memory capacity during parachuting: a possible cause of ‘no pull’ fatalities
Working memory capacity of novice and experienced parachutists was compared under three conditions: prior to exiting the aircraft, on landing and during a control, non‐jumping day. Analysis of the operation span task revealed significant impairments in both storage and processing capacities of working memory prior to jumping. Storage capacity continued to be impaired in novice parachutists on landing whilst experienced parachutists showed full recovery. Neither group showed impairment in processing capacity on landing. Significant increases in heart rate were found for both groups in the jump and landing conditions compared to baseline but no differences existed between novices and experienced parachutists. Initial analyses support processing efficiency theory and suggest that cognitive processing may be slowing down during a jump. However, post hoc analysis of incorrect responses suggest that executive function may actually become disrupted. The results are reviewed in the context of ‘no pull’ parachuting fatalities.
