Objective: To evaluate the effect of a campus-wide social norms marketing intervention on alcohol-use perceptions, consumption, and blackouts at a large, urban, public university. Participants: 4,172 college students (1,208 freshmen, 1,159 sophomores, 953 juniors, and 852 seniors) who completed surveys in Spring 2015 for the Spit for Science Study, a longitudinal study of students' substance use and emotional health. Methods: Participants were e-mailed an online survey that queried campaign readership, perception of peer alcohol use, alcohol consumption, frequency of consumption, and frequency of blackouts. Associations between variables were evaluated using path analysis. Results: We found that campaign readership was associated with more accurate perceptions of peer alcohol use, which, in turn, was associated with self-reported lower number of drinks per sitting and experiencing fewer blackouts. Conclusions: This evaluation supports the use of social norms marketing as a population-level intervention to correct alcohol-use misperceptions and reduce blackouts.  相似文献

中国大学生词汇学习中的词典使用情况调查及启示   总被引:1,自引:0,他引:1  
以自行设计的词典使用过程模型为基础对北京一所高校的大学一年级学生在英语词汇学习中的词典使用情况进行了一次调查研究,并对部分受试者进行了跟踪访谈。研究表明,受试者在英语词典使用的三个阶段上有待改进,词典使用的指导训练应及早展开。根据调查中反映的问题,对大学英语教学中的词典使用指导与训练提出了建议。  相似文献

“如何”在现代汉语中的使用率稍低一些。不过,它功能较多,能构成各种不同结构的句式。如“如何+VP/AP”、“NP+如何”、“无论/不管+如何”、“V得+如何”、“如何如何+AP/VP”、“NP+如何如何”、“VP+如何如何”、“如何如何+NP”等。论文从单用、叠用、连用角度归纳了“如何”的主要用法,并具体解释了它在不同语境下的具体意义。  相似文献

“复用”是指疑问代词在句子中重复出现两次以上的使用现象。笔者整理了近代汉语中疑问代词“多少”复用的主要格式,如“V1+多少+V2+多少”、“多少+N1+多少+N2”、“N1+多少+N2+多少”。现代汉语中“多少”的复用在已有格式的基础上继续发展,产生了新的格式,如“多少+多少”、“多少+N+多少+量词”、“多少+量词+(N1)+多少+量词+(N2)”。  相似文献

As STD infections including HIV increase in the United States, it has become increasingly important to policy makers to ascertain the extent to which knowledge and perceptions of AIDS risk affect an individual's probability of altering their sexual or contraceptive behavior to avoid infection. This paper examines the extent to which women's perceptions of their own and their partners' risk of HIV infection affects the probability of using a condom for protection against sexually transmitted diseases. This paper also examines the extent to which HIV testing may affect motivation for condom use. Crosstabulations reveal that prophylactic condom use is more prevalent among women who have been tested for HIV and increase as perceptions of their chance (and their partner's chance) of being positive increases. The multivariate results from this study indicate that having an HIV test significantly predicts the likelihood of using a condom for STD prevention for US women. Furthermore, women who perceive themselves to be at least somewhat likely to be HIV positive have a higher probability of using a condom to prevent sexually transmitted disease, and women who perceive their partners to be HIV positive are twice as likely as other women to use a condom for STD prevention. However, women who consider themselves likely to be HIV positive are no more likely to use a condom than those who consider themselves not at risk.  相似文献

This paper draws on Bourdieusian concepts to examine the social mechanisms driving service ‘choices’ for marginalised young substance users. In doing so, it problematises the individualised understandings of ‘choice-making’ common in the existing literature. The paper uses interview data collected from 26 young substance users to describe the resources they bring to their service encounters, the capitals that they acquire through these interactions, and the ways in which these are mobilised within the fields in which they operate. The analysis finds that services acted as capital-building settings – participants acquired material resources and opportunities for skill-building, and they built relationships that contributed to a positive sense of identity and belonging. But the exchange potentials attached to these capitals were restricted by the logics of service fields that cast them as deficit and limited their opportunities to build productive forms of social capital. By revealing the social mechanisms behind service ‘choices’, the analysis suggests that the most effective services are those that maximise the opportunities for their young clients to build ‘weak ties’, such as with a diverse range of adults who themselves possess resources, and those that acknowledge the identities that young people already possess as rational and self-managing.  相似文献

This study assesses the association of 12th-grade student factors (e.g., grades, classroom misbehaviors) with substance use (i.e., binge drinking, cigarette smoking, marijuana) across large, medium-sized, and nonmetropolitan areas. Based on a sample of 2,189 students from the 2013 Monitoring the Future data set, logistic regression analyses showed that poor student academic and behavioral factors were associated with higher substance use after controlling for gender, race, and socioeconomic status. Interaction analyses further showed no significant differences in the influence of student factors on substance use across locales. Results suggest that prevention efforts against substance use should target student factors regardless of area of residency.  相似文献

Research has found significant benefits in using exercise as an adjunct treatment for substance use. This study used a qualitative grounded theory approach to explore the role of group exercise on maintaining sobriety. Sixteen persons (13 White men and 3 White women, age M = 31.81, SD = 8.23), recruited from a substance use recovery group that meets at a gym in an urban area in the Southeast part of the United States, were individually interviewed. Data were analyzed using Charmaz’s (2006) constructivist grounded theory strategies. Central themes revealed a parallel process between the steps taken to seek sobriety and those taken to maintain sobriety. The driving forces of sobriety success in both was 12 steps and group exercise programming that included elements of mentorship, structure, accountability, and fellowship or community. This study supported the use of physical group exercise as an adjunct treatment option for substance use treatment.  相似文献
