The specific gravity and buoyancy of 98 men were calculated at various lung volumes. The data indicated that all subjects would be capable of floating in either freshwater or seawater at total lung capacity. At functional residual capacity, the value approximating the lung volume of a recently dead body, 69% of the subjects would float in seawater, whereas only 7% would float in freshwater. Results of this study indicate that while drowned bodies are more likely to sink than bodies dead of other causes, no conclusion regarding the cause of death can be made on the basis of whether bodies float or sink. 相似文献

Gender and gender-role orientation differences were explored on adolescents' coping with peer stressors. Eighth-grade and ninth-grade public junior high school students (N = 285) completed the COPE, reporting the strategies they recently used to deal with a stressful peer-related situation. Measures of gender-role orientation (Bem Sex-Role Inventory) and demographic information also were obtained. Factor analysis of the COPE revealed 4 distinct coping factors: active, avoidant, acceptance, and emotion-focused. The most frequently reported stressful event was arguments/fights with same-sex friends. Girls reported more arguments/fights with opposite-sex friends. Boys reported more physical fights and threats. Students' ratings of how much the situation mattered were used as a covariate in a MANCOVA to compare coping by gender and gender-role orientation, to control for perceived stressfulness of situations. Significant gender-role orientation differences were found for active, acceptance, and emotion-focused coping. 相似文献

The Civil Service under One Country, Two Systems: The Cases of Hong Kong and the People's Republic of China 总被引:1,自引:0,他引:1
Hon S. Chan 《Public administration review》2003,63(4):405-417
Under the principle of "one country, two systems," Hong Kong's and China's civil services are changing, but they clearly are not converging. The civil service reforms made in Hong Kong and China appear to be heading toward two logical extremes: one toward strengthening political authority over the civil service, and the other instituting greater institutionalization. What appears to be a problem in Hong Kong may be seen as a solution in China. Not only reform problems, but also reform options, are defined in relation to wider political institutions and changing socioeconomic dynamics. The study shows that while some things do need to be uniform, such as loyalty to the state and central government, a great deal of flexibility regarding administrative systems within one country is possible. There can be a modern nation without a truly national civil service. 相似文献

Habit is a frequently mentioned but understudied cause of political action. This article provides the first direct test of the hypothesis that casting a ballot in one election increases one's propensity to go to the polls in the future. A field experiment involving 25,200 registered voters was conducted prior to the November general election of 1998. Subjects were randomly assigned to treatment conditions in which they were urged to vote through direct mail or face-to-face canvassing. Compared to a control group that received no contact, the treatment groups were significantly more likely to vote in 1998. The treatment groups were also significantly more likely to vote in local elections held in November of 1999. After deriving a statistical estimator to isolate the effect of habit, we find that, ceteris paribus, voting in one election substantially increases the likelihood of voting in the future. Indeed, the influence of past voting exceeds the effects of age and education reported in previous studies. 相似文献
