Abstract

Background: Young adults remain the earliest legal target for the tobacco industry. Against this, the existence of smoking policies would appear to offer some protection to students on campus. However, little research has been conducted into the outcomes of such policies from a student perspective. Methods: The authors conducted 8 focus groups at 4 selected Canadian undergraduate campuses to investigate student perceptions and behaviors resulting from campus smoking policies. Results: Results indicated that student smoking behaviors are minimally impacted by campus smoking policies due to seriously compromised implementation and enforcement. Conclusions: These findings imply that the presence of campus smoking policies and claims of “smoke-free” campuses should not be misinterpreted as achievement and without renewed focus and adequate tobacco control infrastructure, it will remain possible for young adults to initiate and maintain tobacco smoking on campus.  相似文献

Abstract

Objective: Data about college student sleep were collected and used to develop an education campaign to improve sleep. Participants: On-campus residents at a large state university were surveyed on 4 occasions, October 2005 to April 2007. Sample size was 675 to 1,823 students. Fall 2005 mean age = 18.5 years, SD = 1.03 (range 18–30) years. Initial survey included 935 males and 1,859 females (2005–2006). Matched pairs data (2006–2007) included 91 males and 107 females. Twenty-six males and 22 females participated in interviews. Methods: A survey administered online included the Pittsburgh Sleep Quality Index, along with an 8-question in-person interview. Results: Poor sleep interacted with academics and mental health, and an education campaign positively affected student sleep. Conclusions: Teaching students how to effectively manage sleep can improve their well-being. Sleep may also be a gateway topic for health care professionals to address sensitive health issues such as depression.  相似文献

Abstract

Objective: To examine the prevalence of drug-related sexual assaults, identify the frequency of assaults that occur following voluntary versus involuntary drug or alcohol consumption, and identify contextual correlates of drug-related assaults. Participants: College-student females (n = 314). Methods: Volunteers reported experiences with forcible and drug-related sexual assaults in the spring semester of 2004. Follow-up queries regarding the most severe drug-related assaults determined whether the assaults followed voluntary or involuntary alcohol or drug consumption. Results: 29.6% (n = 93) of the respondents reported a drug-related sexual assault or rape; 5.4% (n = 17) reported a forcible sexual assault or rape. Voluntary incapacitation preceded 84.6% of drug-related assaults and involuntary incapacitation preceded 15.4% of drug-related assaults. The majority of drug-related assaults (96.1%) involved alcohol consumption prior to assault. Conclusions: Drug-related sexual assaults on college campuses are more frequent than are forcible assaults and are most frequently preceded by voluntary alcohol consumption.  相似文献

Abstract In this study, we explore the social basis of environmental concern, specifically focusing on attitudes about the agricultural environment in relation to an individual's geographic and social distance from agriculture. We also consider the significance of rural recreational behaviors in relation to agro‐environmental concern. The analysis, based on data from a statewide survey of Ohioans, reveals a strong relationship between one's geographic location along the rural‐urban continuum and attitudes about agriculture and the environment. This relationship, though, does not exist once the effects of social proximity to agriculture are accounted for, suggesting that the relationship between residential location along the rural‐urban continuum and agro‐environmental attitudes may be spurious. The analysis also reveals a strong relationship between participation in rural recreation and attitudes about agriculture and the environment. We describe several conceptual and practical implications of this research for natural‐resource management.  相似文献

Masked activists, self-identifying as anarchists, taking from supermarkets and handing goods to passers-by are the topic of this profile. Over 50 such acts have occurred across Greece since the onset of the financial, political and social crisis in 2008. We present a snapshot of the phenomenon of collective expropriation and position it within a context of further market-oriented forms of resistance to ‘austerity politics’.  相似文献
