Children’s savings account programs are interventions that seek to engage disadvantaged children and their families in early college saving, cultivate college-saver identities, and reduce disparities in educational and economic outcomes. Existing research has revealed positive effects of CSAs on children’s outcomes, but questions remain about how and for whom CSAs facilitate these outcomes. This study uses account data from 493 accountholders and findings from interviews with 50 participants to examine asset accumulation and savings experiences among mostly low income, Latino families in New Mexico’s Prosperity Kids CSA program. One-third of the families made a deposit into their child’s account designated as “savers” with a median total contribution of $123 and a median account balance, including initial seed deposit, of $345. Longer duration of program enrollment and fewer number of unexcused absences predicted savers status. Qualitative findings highlight emerging college-saver identities, viewed through the framework of identity-based motivation, understood to include salience, normalization of difficulty, and group congruence. Qualitative interview data further suggest that initial seed money, deposit incentives, and withdrawal restrictions were important influences on participants’ saving. These findings suggest CSA features that may encourage positive savings outcomes for economically disadvantaged households and, then, that may have implications for future CSA policy development.  相似文献

Prior research suggests that congregational characteristics are associated with the racial attitudes of Black churchgoers. This study examines the relationship between congregational diversity and beliefs about the Black/White socioeconomic gap among Black religious adherents. Drawing upon pooled data from the General Social Survey and the National Congregations Study, we fit binary logistic regression models to estimate the association between congregational diversity and the explanations of Black/White economic inequality among Black religious adherents. Findings from our study reveal that congregational diversity is one factor that accounts for intragroup differences in racial attitudes among Black religious affiliates. Relative to Blacks that attend religious services in overwhelmingly Black congregations, Blacks that attend religious services in congregations that are overwhelmingly White are significantly less likely to attribute Black/White socioeconomic gaps to a lack of educational opportunities. Our study demonstrates that congregational diversity is a source of intragroup variation in racial attitudes among Black religious affiliates, which may attenuate the ability of such congregations to bridge racial divisions.  相似文献

The dearth of research literature on the religious beliefs and practices of African American adolescents has led to increased empirical inquiry, yet a lack of research considers African American adolescents’ religious beliefs and practices as an important developmental milestone. This study explored how African American parents’ religious socialization affected youth religious experiences and served as a culturally specific strength-based asset that promotes psychological well-being. Our sample included a socioeconomically diverse sample of 154 African American families. Accounting for demographics, adolescents’ relationship and communication with God were found to be associated with a healthier psychological well-being. Additionally, parents’ religious socialization impacted the relationship between youths religious beliefs and practice and psychological well-being. Overall, results suggest that parents’ and adolescents’ religious beliefs can promote psychological well-being.  相似文献

This study investigated the association between congregational relationships and personal and collective self-esteem among young Muslim American adults. Mosque-based emotional support and negative interactions with congregants were assessed in relation to personal and collective self-esteem. Data analysis was based on a sample of 231 respondents residing in southeast Michigan. Results indicated that receiving emotional support from congregants was associated with higher levels of collective self-esteem but was unassociated with personal self-esteem. Negative interaction with congregants was associated with personal self-esteem. Together, these findings indicate that mosque-based emotional support and negative interactions function differently for personal and collective self-esteem, which provides evidence that although personal and collective self-esteem are interrelated constructs, they are also conceptually discrete aspects self-evaluations.  相似文献

This study examined racial–ethnic minority and white identified participants’ perceptions of racial microaggressions in four video scenarios involving a white professor and a black student. Participants (N = 261) were randomly assigned to observe a one of the four video conditions. The video involved an interaction with no microaggression, a very ambiguous microaggression, an ambiguous microaggression, or an overt microaggression. Participants rated their observations of (a) negative emotions toward the committer (white professor) and receiver (black student) of the microaggression, (b) positive emotions toward the committer and receiver of the microaggression, (c) perceptions on the degree of biasedness of committer, and (d) degree of positive perceptions of the committer. Analysis compared ratings of two groups, including racial–ethnic minority and white observers. We found a significant difference between the overt condition and other three conditions on negative emotions, positive emotions, and attributions of the professor (i.e., cultural biasedness and positive perceptions). However, there were no differences between the no microaggression, very ambiguous, and ambiguous conditions. No significant differences between racial–ethnic minority and white participants’ ratings were detected. Implications for training, practice, and future research are offered in our discussion.  相似文献

Many Americans endorse a colorblind racial ideology, meaning they strive to “not see race” and emphasize sameness and equal distribution of resources across racial lines. Currently, there is an absence of studies examining the personality and individual difference correlates of racial colorblindness. The current study investigated the association between three different aspects of racial colorblindness (unawareness of racial privilege, unawareness of institutional discrimination, and unawareness of blatant racism) and the Big 5, empathy, and aggression in white undergraduates. Our results revealed two divergent patterns. Unawareness of racial privilege was related to lower openness and perspective taking, but more empathic concern, whereas unawareness of blatant racism and unawareness of institutional discrimination were related to lower agreeableness, perspective taking, and empathic concern. These results are discussed in relation to the broader literature on prejudice and personality.  相似文献

Muslims constitute about 14% population of India and are the largest religious minority community spread over the length and breadth of the country. The minority community in question has been relegated to the lowest socio-economic stratum in Indian society especially after the partition and independence of the country. However, in the state of Jammu and Kashmir, Muslims are in majority constituting about 67% population of the state. In the current study, the Concentration Index of Muslim population, variation in literacy rate and work participation, occupational structure across region and religion, as well as the interrelationship between concentration of Muslim population, literacy rate and work participation in Jammu and Kashmir has been explored and explained. The present study is based upon secondary information obtained from Census 2001 and is also supplemented with government reports, published work wherever necessary. As far as share of Muslims in the sphere of education and employment in the state of Jammu and Kashmir is concerned, they have reported lower share among the population of literates, category of other workers and higher share in the occupational category of cultivators, agricultural labourers, household industry workers and non-workers in comparison to all religious groups. This means that despite being in majority, their situation is similar to their co-religionists at the all India level.  相似文献

This paper examines the experiences and views of 12 Caribbean students studying at four Liberal Arts colleges and one large university in the Northeast, USA. The purpose of the study was to ascertain how young educated potential immigrants to the US today are thinking about race, identity, and homeland. The data were gathered through a 12-item open-ended questionnaire electronically administered through Google Forms. Among other issues, the researcher wanted to learn about participants’: decision to study in the US, experiences with race, identity and attitudinal shifts, feelings about being assigned racial labels, and current thinking about returning to their home countries. The findings highlight the acceptance of racial labels except for ‘African American’, a dogged adherence to national identity, the challenge of adjusting to the US racialized space, the view of the US as an education and economic transitional point for migrants on their return journey to their home countries, the formulation of new understandings and attitudes regarding mixed ancestry, and the defining role of sexual orientation in the attitude towards home country versus the US.  相似文献

In order to make feedback as effective as possible, it is important to understand its function in the three-term contingency (TTC) and the impact of various factors involved in delivering feedback. Timing of feedback is one factor that can affect the impact of feedback on learner’s behavior. An analysis of timing of feeback may help us getting closer to better understanding how feedback functions in the TTC. The purpose of this study was to evaluate the effects of feedback at different temporal locations. Specifically, feedback was provided either immediately (a) after a teaching session or (b) before the following teaching session, on teaching performance of undergraduate psychology students. The results indicated that feedback provided before the teaching session was more effective in improving teaching skills than feedback that was provided after the session. These findings suggest that feedback may function primarily as an antecedent to future performance and not necessarily as a consequence for past performance. However, the behavioral mechanism that explains these results is not yet clear. Future studies should investigate this further by manipulating the content of feedback prior to the teaching performance.  相似文献

Organisations are becoming increasingly aware of the importance of employees in gaining and maintaining competitive advantage. The happy worker–productive worker thesis suggests that workers who experience high levels of well-being also perform well and vice versa; however, organisations need to know how to ensure such happy and productive workers. The present review and meta-analysis identifies workplace resources at the individual, the group, the leader, and the organisational levels that are related to both employee well-being and organisational performance. We examine which types of resources are most important in predicting both employee well-being and performance. We identified 84 quantitative studies published in print and online from 2003 to November 2015. Resources at either of the four levels were related to both employee well-being and performance. We found no significant differences in employee well-being and organisational performance between the four levels of workplace resources, suggesting that interventions may focus on any of these levels. Cross-sectional studies showed stronger relationships with well-being and performance than longitudinal studies. Studies using objective performance ratings provided weaker relationships between resources and performance than self-rated and leader/third-party-rated studies.  相似文献
