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

Ethnic group differences in the contributions of self-definition (self-worth and efficacy) and interpersonal relatedness with parents and peers to changes in psychological and school adjustment were examined among 448 White, Black, and Latino girls and boys (11–14 years of age). Self-report questionnaires and school records were evaluated for socioeconomic and ethnic group differences in patterns of change over 1 year. Overall similarity in changes over time across ethnic groups was found for relatedness, self-definition, and psychological adjustment, although Black and Latino youth reported more overall adjustment difficulties, Black youth reported less positive relationships with parents, and lower SES youth reported less positive peer relationships than others. Ethnic group differences in changes to school adjustment, even after controlling SES, suggested a cultural variation in which often cited declines in school adjustment during middle school characterize White adolescents to a greater degree than Black or Latino adolescents. Ethnicity moderated associations of relatedness and self-definition with psychological and school adjustment such that Black and Latino youth appeared particularly vulnerable to experiences that threaten closeness and trust in relationships. Results pointed to potentially important situational and cultural differences in maladaptive and adaptive developmental processes across ethnicity.  相似文献

Empathy, prosocial behavior, the number of friends, self-reported popularity, and various forms of interpersonal forgiveness were examined as predictors of peer victimization among 52 7th and 8th graders attending a private school. Popularity was the strongest individual predictor of teacher-reported victimization with high popularity associated with low victimization. Malestudents reported significantly higher rates of victimization than females, prompting the decision to examine correlates of self-reported victimization separately by gender. Interpersonal forgiveness scores were the strongest predictors of self-reported victimization; however, different forms of forgiveness were the greatest predictors of male and female self-reported victimization. Implications are discussed.  相似文献

The Positive Psychology of Interested Adolescents   总被引:5,自引:0,他引:5  
Using the experience sampling method (ESM) and a diverse national sample of young people, this study identifies two groups of adolescents: those who experience chronic interest in everyday life experiences and another who experience widespread boredom. These groups are compared against several measures of psychological well-being: global self-esteem, locus of control, and emotions regarding one's future prospects. It is hypothesized that a generalized chronic experience of interest, an innate physiological function, can be used as a signal for a larger measure of psychological health, while chronic boredom is a sign of psychic dysfunction. A strong association between the experience of interest and well-being was found.  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

Recent empirical work suggests that legalconstraints are significant in choosingstate educational grant structures. Unfortunately, the literature has not takensuch constraints into account, thus callinginto question particular grant structurerecommendations. This paper studies theconditions under which a legislature, underorder to reform its educational grantstructure, prefers foundation grants overdistrict power equalization grants. Atheoretical model is presented in which thechoice is shown to depend on the legalbasis of the court's decision, and theempirical validity of this conclusion isdemonstrated using Connecticut data and aseparate model of school districtexpenditure choice.  相似文献

This article determines the conditions under which theSouthern countries should act together, or separately, whilenegotiating with the North about climate change policy andabout the conditions for future Southern engagement. The papermodels the international negotiations with complete and withasymmetric information in a dynamic framework.

This study seeks to advance our understanding of the institutionalunderpinnings of federalism by evaluating William H. Riker'sstudy of party causality. Using data from federal funds transfersin Argentina, a federation exhibiting high levels of fiscaldecentralization despite its centralized party system, it isshown that when governorships are held by opposition parties,the overall amount of federal funds transferred to provincesincreases considerably. In addition, changes in the partisancomposition of the national government are also associated withsteep increases in the share of provincial federal funds, whereas,more controversially and challenging prominent recent studiesof decentralization in Latin America, divided government atthe national level leads to centralization of intergovernmentalfunds. These findings support Riker's contention that politicalparties exercise a decisive influence over the distributionof fiscal powers between states and the national government.  相似文献

In this article we evaluate two claims made in recent studies of the welfare states of advanced industrial societies: first, that welfare states have remained quite resilient in the face of demands for retrenchment; and second, that partisan politics have ceased to play a decisive role in their evolution. Addressing the first claim, we present analysis from a new data set on unemployment insurance and sickness benefit replacement rates for 18 countries for the years 1975–99. We find considerably more evidence of welfare retrenchment during the last two decades than do recent cross-national studies. Second, we examine the "end of partisanship" claim by estimating the effects of government partisanship on changes in income replacement rates in sickness and unemployment programs. Our results suggest that, contrary to claims that partisanship has little impact on welfare state commitments, traditional partisanship continues to have a considerable effect on welfare state entitlements in the era of retrenchment .  相似文献
