Most of the studies on the determinants of individual gambling behaviour rely on cognitive theories. In our study, we argue that, besides cognitive factors, several social factors might play an important role as well. We analyse data from an ad hoc webmail survey conducted on about 2000 undergraduate students enrolled in a large public university in the Northern Italy in the academic year 2012–13. Using a variety of statistical techniques (standard regression models, boosted regression trees and structural equations models), we show that social variables affect both participation in gambling in the past year and latent gambling propensity. In particular, controlling for several proxies for individual cognitive ability and understanding of probability, gambling propensity is positively affected by the degree of gambling in the social surrounding (parents, peers, neighbourhood) and the acceptability of gambling activities to the individual. Moreover, in our sample of college students the role of social factors appears to be larger than that of cognitive factors, and this is consistent across different types of models and specifications. 相似文献

Research finds lower levels of academic performance among sexual minority high school students, but some studies suggest sexual minorities have higher levels of educational attainment in adulthood. To further our understanding of how and why sexual orientation is associated with educational success, this study turns attention to the pathways to college completion, examining points along educational trajectories in which sexual minorities fall behind or surpass their heterosexual peers. Using data from the National Longitudinal Study of Adolescent to Adult Health, we find that sexual minority women are less likely than women with no same-sex sexuality to complete college, in part due to their high school performance and transition into college. Men who experience same-sex sexuality only in adolescence struggle in high school, but men who experience same-sex sexuality for the first time in adulthood are more likely to earn a college degree than men who do not experience same-sex sexuality. 相似文献

Objective: To investigate sexual orientation differences in college men's motivations for HIV testing. Participants: 665 male college students in the Southeastern United States from 2006 to 2014. Methods: Students completed a survey on HIV risk factors and testing motivations. Logistic regressions were conducted to determine the differences between heterosexual men (HM) and sexual minority men (SMM). Results: SMM were more motivated to get tested by concern over past condomless sex, while HM were more often cited supporting the testing program “on principle” and wanting a free t-shirt. SMM and HM differed in behaviors that impact HIV risk and other demographics. However, differences in testing motivation by concern over past condomless sex or wanting a free t-shirt persisted when controlling for these demographic and behavioral differences. Conclusions: Appropriately designed HIV prevention interventions on college campuses should target SMM's distinct concern over past condomless sex as a testing motivation. 相似文献

Objective: To analyze the overlap of nonsuicidal self-injury (NSSI) and suicide-related behaviors (SRB) among college students with regard to demographics, mental health, and coping styles. Participants: Respondents were 572 undergraduate students at a southwestern public university. Methods: Data were collected in 2015. Respondents completed a demographic survey and assessments of NSSI, SRB, internalizing symptoms (ie, anxiety, stress, and depression), aggression, and negative coping strategies. The survey was administered via a Web-based procedure. Results: Women reported more frequent cutting behaviors than men. Endorsement of NSSI was also associated with an increased likelihood of lifetime SRB. A subgroup of students endorsing both NSSI and SRB demonstrated poorer mental health, more negative coping, and self-reported female sex. Conclusions: College healthcare providers may benefit from competency-based training in techniques for the combination treatment of NSSI and SRB, as well as culturally based models of suicide. 相似文献

Objective: The current research aimed to understand differences in smoking-related identity among college students and to illustrate the distinct characteristics of nonidentified smokers (NIS). Participants: Students from 2 colleges in Massachusetts (N = 538; April 2016). Methods: Respondents reported by online survey whether or not they had smoked a cigarette in the past 30 days and if they self-identified as smokers. Nonsmokers (NIS) and identified smokers (IS) were then compared on their smoking attitudes and behavior. Results: NIS made up 12.5% of the sample and 64% of all tobacco users. NIS perceived themselves as less addicted and were more confident in their ability to quit smoking. They also were less likely to smoke alone, buy their own cigarettes, or have friends who smoked. Conclusions: College health officials can best motivate NIS to quit smoking by focusing on peer norms and the potential of long-term addiction. 相似文献

Middle school is the appropriate time for students to begin exploring careers and improving self‐efficacy; however, empirically supported career and college readiness interventions for U.S. middle school students are limited. Examining the effect of an intervention that combined a virtual experience and a local college visit on middle school students (99 girls, 74 boys), the authors found that participating students had higher levels of college and career self‐efficacy than did nonparticipating students. The study shows that a workshop of the online Florida CHOICES program coupled with a campus visit increased middle school student career and college self‐efficacy. Future research should include longitudinal studies and use of diverse populations to improve generalizability of study results. 相似文献

试论国家助学贷款良性运行机制建立之对策 总被引:1,自引:0,他引:1

国家助学贷款是利用金融手段完善我国普通高校资助政策体系,加大对经济困难学生资助力度所采取的一项重大措施。运行中存在问题是当前市场经济法制不健全、社会信用部分失范的必然结果。要形成大学生助学贷款良性运行机制,必须建立国家、银行、高校、学生与社会"五位一体"的联合保障机制。最重要的是应尽快建立全国性的以居民身份证号码为依托的"全国大学生信用网",并以此作为建立全国性的信用机制的开端。要在全社会形成一种讲诚信光荣、不讲诚信可耻的持久氛围,让信用缺失者无论在何处都要为自己的行为付出代价。此外还应大力发展学生生源所在地贷款业务。 相似文献
