The authors report findings from the first national survey of gambling among college students. They collected information from 10,765 students attending 119 scientifically selected colleges included in the 2001 Harvard School of Public Health College Alcohol Study (CAS), which indicated that 42% of responding students gambled in the last school year and 2.6% gambled weekly or more frequently. These findings contradict the widely held opinion based on previous studies that gambling is prevalent among college students. Previous studies used convenience samples that might have overestimated the risk for gambling problems. Male students and students of legal age (> or = 21 y) were more likely than others to gamble. Availability of gambling, measured by the number of types of gambling venues located in the schools' states, influenced their decisions to gamble. The concordance of characteristics associated with both gambling and binge drinking suggested a disposition to take risks that is independent of the risk objects.  相似文献

The authors examined changes in college students' illicit drug use, patterns of polydrug use, and the relationship between students' ages of initiation of substance use and later use of marijuana and other illicit drugs between 1993 and 2001. Data from 119 US colleges and universities in the Harvard School of Public Health College Alcohol Study were used in the study. They found significant increases in percentages of students' use of marijuana in the past 30 days (from 13% to 17%), past year (from 23% to 30%), and lifetime (from 41% to 47%) between 1993 and 2001, with most of the increase occurring between 1993 and 1997. Past 30-day use of other illicit drugs increased from 4% to 7% and past year use increased from 11% to 14%. More than 98% of marijuana and other illicit drug users used another substance. They also either smoked, were binge drinkers, and/or were users of another illicit drug. Drug prevention programs should emphasize heavy alcohol use and smoking and should start when students are in high school or earlier.  相似文献

Abstract

This study reports the results of a national survey designed to identify the nature and levels of volunteer work that social work educators contribute to the social welfare sector. Findings reveal that nearly all social work educators engage in formal volunteer work and perform a variety of roles in human service agencies. The most common volunteer activities are advocacy, administration and consultation. The least common volunteer activities are evaluation, data management and emergency services. Study results also indicate that tenure status and primary teaching area are positively associated with the amount and type of volunteer work performed.  相似文献

In this paper social interaction is modeled as a consumer good. A model of household production is employed to derive the demand for social interaction. The model shows that the demand for social interaction is a function of its price, the price of other goods and income. The theory is tested with data from the General Social Survey and the results show that social interaction can be explained as the consequence of utility maximizing behavior by individuals. These results are in contrast to social capital theorists who have attributed these changes to factors such as increased community heterogeneity.  相似文献

文章认为,在现代全球化商品生产环境下,构建生产和再生产的社会关系从普遍意义上讲就是阶级关系,提出应重回阶级视角审视和分析农村贫困及其产生原因。在这一视角下对现代农地变迁进行探讨,并在提出当代农耕变化七个命题的基础上,识别了不同阶层关系下的动力机制和不同发展政策议题下隐含的阶级动力,并指出,现有关于改善农业生产、农村生计和福利的政策忽略了阶级不平等性,因此它们也忽略了贫困的根本社会基础以及不同干预对此带来的重要影响。  相似文献
