This study examined how external evaluators' assessments of a management team and its leader are impacted by congruence between the leader's gender and the gender typing of the industry in which the team works. We experimentally tested our theory using industries that are either male typed or gender neutral, with teams led by male and female leaders. Results indicate that performance expectations for the team were more favorable when the leader's gender was congruent with the industry's gender typing, but expectations for the leader were not affected by gender congruence. These findings paradoxically suggest that evaluators form performance expectations for teams based upon individual characteristics of their leaders, even when these characteristics have no effect on the conscious assessments of the leaders themselves. 相似文献

Fatal and nonfatal intentional self‐harm events in eight U.S. states were compared using emergency department, hospital, and vital statistics data. Nonfatal event rates increased by an estimated 24.20% over 6 years. Case fatality ratios varied widely, but two northeastern states' total event rates (fatal plus nonfatal) were very high (New Hampshire 206.5/100,000 person years; Massachusetts 166.7/100,000). Geographic context did not uniformly impact the likelihood of self‐harm across event types. The state‐level public health burden posed by such acts cannot, therefore, be accurately estimated from either mortality or morbidity data alone. 相似文献
