Despite the development of a variety of efficacious alcohol intervention approaches for college students, few student drinkers seek help. The present study assessed students' history of help-seeking for alcohol problems, as well as their estimates of how likely they would be to use various help-seeking resources, should they wish to change their drinking. Participants were 197 college students who reported recent heavy drinking (46% male, 68.5% White, 27.4% African-American). Participants completed measures related to their drinking and their use (both past use and likelihood of future use) of 14 different alcohol help-seeking options. Repeated-measures analyses of variance revealed that students preferred informal help-seeking (e.g., talking to friends and family) over formal (e.g., talking with a counselor or medical provider) and anonymous resources (e.g., internet- or computer-based programs). Higher self-ideal discrepancy, greater depressive symptoms, and more alcohol-related consequences were positively associated with actual past help-seeking. Alcohol-related problems and normative discrepancy were negatively associated with hypothetical likelihood of utilizing all three help-seeking resources. These results suggest that heavy drinking college students prefer low-threshold intervention options including peer, family, computerized, and brief motivational interventions. Only 36 participants (18.3% of the sample) reported that they had utilized any of the help-seeking options queried, suggesting that campus prevention efforts should include both promoting low-threshold interventions and attempting to increase the salience of alcohol-related risk and the potential utility of changing drinking patterns.

Abstract Scattered among the 160 000 images made by the Notman photographic studio of Montreal between 1860 and 1880, and preserved today in the studio's picture books at the McCord Museum, are about two dozen portraits of women who worked for Notman's during that period.1 Their photographs harmonize well with those of the bourgeois women who were Notman clients, sharing poses, expressions, dress, coiffures and attributes. The women are situated in comfortable home-like environments. They pose alone, or as sisters, or as mothers and daughters (never as wives), with attributes of education and leisure, such as books, watercolour sketchbooks or, notably, photographs and albums. Their clothing is always elegant and occasionally sumptuous. 相似文献

More than [3/4] of U.S. college students report a heavy drinking episode (HDE; 5 (for men) and 4 (for women) drinks during an occasion) in the previous 90 days. This pattern of drinking is associated with various risks and social problems for both the heavy drinkers and the larger college community. According to behavioral economics, college student drinking is a contextually bound phenomenon that is impacted by contingencies such as price and competing alternative reinforcers, including next-day responsibilities such as college classes. This study systematically examines the role of these variables by using hypothetical alcohol purchase tasks to analyze alcohol consumption and expenditures among college students who reported recent heavy drinking (N = 207, 53.1% women). The impact of gender and the personality risk factor sensation seeking (SS) were also assessed. Students were asked how many drinks they would purchase and consume across 17 drink prices and 3 next-day responsibility scenarios. Mean levels of hypothetical consumption were highly sensitive to both drink price and next-day responsibility, with the lowest drinking levels associated with high drink prices and a next-day test. Men and participants with greater levels of SS reported more demand overall (greater consumption and expenditures) than women and students with low SS personality. Contrary to our hypotheses women appeared to be less sensitive to increases in price than men. The results suggest that increasing drink prices and morning academic requirements may be useful in preventing heavy drinking among college students.

Soil erosion and sediment yield and their relationships with vegetation cover in upper stream of the Yellow River 总被引:5,自引:0,他引:5
Soil erosion is a significant concern when considering regional environmental protection, especially in the Yellow River Basin in China. This study evaluated the temporal-spatial interaction of land cover status with soil erosion characteristics in the Longliu Catchment of China, using the Soil and Water Assessment Tool (SWAT) model. SWAT is a physical hydrological model which uses the RUSLE equation as a sediment algorithm. Considering the spatial and temporal scale of the relationship between soil erosion and sediment yield, simulations were undertaken at monthly and annual temporal scales and basin and sub-basin spatial scales. The corresponding temporal and spatial Normalized Difference Vegetation Index (NDVI) information was summarized from MODIS data, which can integrate regional land cover and climatic features. The SWAT simulation revealed that the annual soil erosion and sediment yield showed similar spatial distribution patterns, but the monthly variation fluctuated significantly. The monthly basin soil erosion varied from almost no erosion load to 3.92 t/ha and the maximum monthly sediment yield was 47,540 tones. The inter-annual simulation focused on the spatial difference and relationship with the corresponding vegetation NDVI value for every sub-basin. It is concluded that, for this continental monsoon climate basin, the higher NDVI vegetation zones prevented sediment transport, but at the same time they also contributed considerable soil erosion. The monthly basin soil erosion and sediment yield both correlated with NDVI, and the determination coefficients of their exponential correlation model were 0.446 and 0.426, respectively. The relationships between soil erosion and sediment yield with vegetation NDVI indicated that the vegetation status has a significant impact on sediment formation and transport. The findings can be used to develop soil erosion conservation programs for the study area. 相似文献
