This study used a career capital framework to compare the relative role of mentoring and three other forms of career capital (human, agentic, and developmental network capital) in predicting career success. Using a three-wave longitudinal design we found that mentoring added value, above and beyond the other forms of career capital, in predicting promotions and advancement expectations. However, although mentoring mattered for career success, it represented just a part of a constellation of career resources that are embedded within individuals and their relationships. Implications for future research are discussed.  相似文献

Form A of the Dysfunctional Attitude Scale (DAS-A), a self-report measure of depressive beliefs, is widely used to test Beck's cognitive model of depression. The present study is the first to evaluate the DAS-A factor structure in an adolescent population of 542 high school juniors and the first to examine a hierarchical model. Findings support the existence of a hierarchical structure consisting of two conceptually meaningful group factors (Dysfunctional Attitudes About Achievement and Dysfunctional Attitudes About Needing Approval), a method factor consisting of reverse-worded items, and a general factor, which accounts for 65% of the variance in total scores. The general factor is related to sociotropy, autonomy, and neuroticism, whereas the Dysfunctional Attitudes About Achievement and Dysfunctional Attitudes About Needing Approval factors demonstrate convergent and discriminant validity with respect to autonomy and sociotropy. The structure displays partial metric invariance in female and male students as well as in Caucasian and Non-Caucasian students.  相似文献

The purpose of this investigation was to assess the reliability and validity of eight developmental asset measures among a stratified, random sample (N = 540) of college students to guide health promotion efforts. The sample was randomly split to produce exploratory and confirmatory samples for factor analysis using principal axis factoring and varimax rotation and structural equation modeling techniques. Items were retained on factors if they had high loadings greater than .40 and were not complex. Concurrent validity was examined among substance use (including alcohol and tobacco) and sexual risk-taking variables. Exploratory and confirmatory samples did not differ on demographics. Parallel analysis confirmed the eight theorized constructs. Exploratory factor loadings were greater than .40. Concurrently, validity analyses were in the predicted direction. Cronbach alphas were .70 or greater with the exception of the Future Aspirations asset. Preliminary analyses support the reliability and validity of measuring developmental assets among emerging adults. Implications and potential uses are discussed.  相似文献

本文介绍的两个“芬兰双生子(Finn Twin)”研究是对10个出生组的青少年双生子及其家庭的长期跟踪研究。本文概述了这两个项目对遗传与环境的关联和互动对吸烟饮酒行为影响的研究。这些研究的结果提示个体差异对吸烟饮酒行为的长期变动的影响受到兄弟姐妹互动、同伴互动以及父母教养方式的调节。环境对吸烟饮酒的影响主要表现在学校、居住社区与家庭环境的差异上。环境与遗传影响的程度和持久度有城乡差异。遗传的影响受居住社区的制约。多阶段模型的分析揭示了遗传与环境的互动对这些行为的演变(从试吸试饮到发展到滥用)的动态的影响,遗传似乎对吸烟饮酒的共同轨迹更有影响。这些结果对今后本项目对这约1万对芬兰成年双生子的分子遗传学研究提供了有益的线索  相似文献

This article presents the results of a secondary analysis of the housing-related variables contained in a survey of the settlement experiences of some 400 regularized refugee claimants living in Greater Montréal. It examines housing as a vector of settlement and integration, as well as the related neighbourhood context. The data indicate that the refugees are relatively well housed in terms of dwelling quality, but spend inordinately high percentages of their income on rent, essentially because of their low incomes. More optimistically, the refugees have access to social support from within their ethnolinguistic group, and in their neighbourhoods they are not isolated from the majority cultural groups of Québec society.  相似文献

We describe our ethics‐driven process of addressing missing data within a social network study about accountability for racism, classism, sexism, heterosexism, cis‐sexism, ableism, and other forms of oppression among social justice union organizers. During data collection, some would‐be participants did not return emails and others explicitly refused to engage in the research. All refusals came from women of color. We faced an ethical dilemma: Should we continue to seek participation from those who had not yet responded, with the hopes of recruiting more women of color from within the network so their perspectives would not be tokenized? Or, should we stop asking those who had been contacted multiple times, which would compromise the social network data and analysis? We delineate ways in which current discussions of the ethics of social network studies fell short, given our framework and our community psychology (CP ) values. We outline literature that was helpful in thinking through this challenge; we looked outside of CP to the decolonization literature on refusal. Lessons learned include listening for the possible meanings of refusals and considering the level of engagement and the labor required of participants when designing research studies.  相似文献
