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

本文追溯了欧洲一体化理论理性选择和社会建构的思想渊源;考察了近年来欧洲一体化研究中理性主义和建构主义在理论和经验层面从论战走向对话的过程;进而以欧盟制宪进程为例分析了社会建构和理性选择机制对这一条约改革过程所具有的解释力及其实现进一步理论融合的潜力.作者认为,这一理论论争表现出搁置元理论层面的分歧,强调理论范式间的通约性,注重问题意识,努力建构超越范式之争的中观理论的特征;这些理论探索也为更广义的国际关系理论发展提供了启示. 相似文献

Using the UN Comtrade database and multiple sources of agricultural investment data, this paper outlines the emerging patterns of food trade and agricultural investment between Southeast Asian countries and China. The paper shows that China has adopted a flexible overseas food strategy. First, China has increased food export and shifted its food trade with Southeast Asia from a dependent relationship towards a complementary relationship at the regional level in recent years. Second, China tends to adapt to the existing conditions of food production and trade in Southeast Asian countries instead of fundamentally altering them. Finally, Chinese overseas agricultural investment is less driven by domestic food demand but more oriented for profit making, and this gives it flexibility in diversifying investment. An adequate understanding of China’s flexible food strategy in bilateral and multilateral relationships holds implications for global food security. 相似文献

Variable selection for semiparametric proportional hazards model under progressive Type-II censoring
Variable selection is an effective methodology for dealing with models with numerous covariates. We consider the methods of variable selection for semiparametric Cox proportional hazards model under the progressive Type-II censoring scheme. The Cox proportional hazards model is used to model the influence coefficients of the environmental covariates. By applying Breslow’s “least information” idea, we obtain a profile likelihood function to estimate the coefficients. Lasso-type penalized profile likelihood estimation as well as stepwise variable selection method are explored as means to find the important covariates. Numerical simulations are conducted and Veteran’s Administration Lung Cancer data are exploited to evaluate the performance of the proposed method. 相似文献

Drawing upon findings from a national evaluation of student social workers' experiences of ‘non-traditional’ placements with a national charity, this article considers what such placements can contribute to the development of an individual and collective sense of professional identity for social work. This is explored against the background of current developments in social work education in England, including changes to the requirements for practice placements and the introduction of ‘fast-track’ routes to qualification, preparing students for social work in statutory children's services. The article suggests that with the establishment of The College of Social Work and the development of the Professional Capabilities Framework, relevant to all social workers throughout their careers, the profession has an opportunity to promote a concept of social work in England beyond that required by statutory sector employers; and that practice learning in non-statutory and non-traditional settings has an important role to play in this. 相似文献

多维视角下的中国家庭婚姻研究结构、关系、家族和文化 总被引:1,自引:0,他引:1
20世纪80年代以来,社会形态、经济结构的巨大变化使原有的社会规范被打破,新的价值观念和价值判断出现,整个世界都在发生着巨变,家庭毫无例外地经受着前所未有的考验,出现了所谓的“家庭危机”。有的西方学者把它概括为六大危机,又称“六D危机”,即违背期望(Deviations from expectations)、丧失荣誉(Disgrace)、经济萧条(Depression)、家庭成员分离(Departure of family members)、离婚(Divorce)、死亡(Death)(张怀承,1993)。在这样的一个大背景下,家庭婚姻的研究面临着许多新的课题,研究的内容不断扩展,研究的手段不断更新,研究的问题也逐渐深化。本文梳理了近年来学者对社会变迁背景下家庭变化的多种现象描述和理论解释,试图对近年来有关家庭婚姻的研究进行一个综合。 相似文献

政治关联、财务绩效与企业社会责任——来自中国化工行业上市公司的证据 总被引:1,自引:0,他引:1
以2007-2011年中国化工行业上市公司为样本,实证考察了政治关联、财务绩效和企业社会责任之间的关系。将政治关联划分为代表委员类和政府官员类两种类型。研究发现,不同类别的政治关联方式对企业社会责任的影响路径存在显著差异。具体表现为,高管的代表委员类政治关联正向作用于企业财务绩效,而财务绩效的提升会促使其更好地履行社会责任。而且,在控制了财务绩效的影响后,代表委员类政治关联对企业社会责任仍具有显著的正向影响,其政治关联的级别越高,企业的社会责任表现越好。这说明财务绩效在两者之间起着部分中介作用;然而,政府官员类政治关联会降低企业的财务绩效。在控制了财务绩效的影响后,其对企业社会责任的影响并不显著,表明了财务绩效在政府官员类政治关联和企业社会责任之间起着完全的中介作用。 相似文献
