There is increasing divergence in the academic outcomes of African American males and females. By most accounts, males are falling behind their female peers educationally as African American females are graduating from high schools at higher rates and are going on to college and graduate school in greater numbers. Some have suggested that school completion and performance is associated with how students feel about themselves. The purpose of this study was to explore gender differences in the relationship between self-perceptions and 2 academic outcomes among a sample of 243 African American high school sophomores. The results suggest that, overall, females are more favorably oriented toward high school completion. Both male and female students with more positive self-perceptions have stronger intentions to complete the current year of high school. Higher grade point averages were more strongly associated with greater self-efficacy for females than for males. Given these findings, increased attention to educational programming, societal messages, and future research is warranted.  相似文献

Voting May Be Habit-Forming: Evidence from a Randomized Field Experiment   总被引:1,自引:2,他引:1  
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

This article builds on a Transparency International (TI)‐sponsored research study funded by the Dutch Government into the National Integrity System (NIS) in practice. The NIS is a framework approach developed by TI that proposes assessing corruption and reform holistically. The NIS not only looks at separate institutions or separate areas of activity or separate rules and practices, but also bases its perspective on institutional and other inter‐relationships, inter‐dependence and combined effectiveness. The study involved 18 countries, using in‐country researchers and an overview report. This article assesses the findings of the study to consider how the approach can work in practice, and what the approach can reveal about the causes and nature of corruption as well as the implications for reform.
