Negotiating in a highly competitive environment may prove particularly challenging for women. We describe three experimental studies that investigated and documented differences in the competitive behaviors of men and women.The first study examined gender differences in competitive performances. In a setting in which men and women performed at similar levels in single-sex competitions, men were...

Men outperform women in many athletic endeavors due to physiological and anatomical differences (e.g. larger and faster muscle); however, the observed sex differences in elite athletic performance are typically larger than expected, and may reflect sex-related differences in opportunity or incentives. As collegiate rowing in the United States has been largely incentivized for women over the las...

design models of multi- stage, axial flow compressor are developed for gas turbine engines. axial flow compressor is one of the most important parts of gas turbine units. therefore, its design and performance prediction are very important. one-dimensional modeling is a simple, fast and accurate method for performance prediction of any type of compressors with different geometries. in this appro...

in the previous two parts of educational manuscript series in emergency, we explained some screening characteristics of diagnostic tests including accuracy, sensitivity, specificity, and positive and negative predictive values. in the 3rd  part we aimed to explain positive and negative likelihood ratio (lr) as one of the most reliable performance measures of a diagnostic test. to better underst...

introduction: pharmacists and pharmaceutical services are among the most important resources and programs in providing health for a society. pharmacists as the key players in presenting health services, greatly impact on the health of a society and if they suffer low job satisfaction, their dissatisfaction may relatively threaten health in a society. this study was conducted to determine irania...

S ex differences in elite athletic performance have been of long-standing interest to physiologists. For example, the 10%–12% sex gap observed for most running world records and elite competitions spurred numerous studies on the contributors to maximal oxygen consumption (4). Moreover , the sex gap varies substantially across sports and age groups, and this variation has stimulated further phys...

The results of two experiments support the thesis that emotional perspective taking entails two judgments: a prediction of one’s own preferences and decisions in a diVerent emotional situation, and an adjustment of this prediction to accommodate perceived diVerences between self and others. Participants overestimated others’ willingness to engage in embarrassing public performances—miming (Expe...

Background: The fastest Ironman race times in ‘Ironman Hawaii’ were achieved in very recent years. This study investigated the change in sex difference in both race performance and the age of peak performance across years in the top ten athletes for split disciplines and overall race time in the ‘Ironman Hawaii’ between 1983 and 2012. Methods: Changes in split times, overall race times, and age...
