Abstract Objectives, Participants, Methods: Drinking game participation has increased in popularity among college students and is associated with increased alcohol consumption and alcohol-related problems. The current study investigated drinking game participation among 133 undergraduates attending National Alcohol Screening Day (NASD) in April of 2007. Results: A large percentage of the sample reported lifetime (77%) and recent (52%) drinking game participation. Males were more likely to report recent participation and reported higher levels of consumption while playing drinking games. Drinking game participants were more likely to experience a range of alcohol-related problems, and the relationship between drinking game participation and alcohol-related problems was mediated by weekly alcohol consumption. Conclusions: These results suggest that drinking game participation is a risk factor for elevated levels of alcohol consumption and alcohol-related problems. Programs should be developed to educate students about the risks of drinking game participation, and prevention programs like NASD should address drinking games. 相似文献

A simple proof of Siegmund's result on the relation between dual q-matrices and dual transition functions for Markov chains is given. A byproduct is a uniqueness result for minimal solutions of stochastically monotone q-matrices. 相似文献

Analysis reported here examined youth in residential group home placements in order to better understand how sexual behaviors,
drug use, and environmental experiences differ by race and gender subgroups. Data were collected from 336 youth aged 14–21
residing in one of 41 group homes in Maryland. Chi square and logistic regression analyses were done to determine differences
on study variables among the race-gender groupings. Results demonstrate not only significant health concerns overall but notable
differences were also found between race-gender subgroups. Findings suggest that found race-gender subgroup differences might
be informative for tailoring programming for youth of residential group home settings. 相似文献

The author was involved in the 1973–1974 acquisition chase in the U.K. and in the Pacific Basin while working for a British company noted for its acquisitiveness. A mystique has grown up around those people who buy companies and individuals who surround themselves with secrecy and charisma are hiding one essential fact; appraising target companies is not very different from appraising any other direct investment. In fact the task lends itself to a combination of simple economics and plenty of common sense. 相似文献

In this paper a method for the construction of a class of row-column designs with good statistical properties and high efficiency is presented. The class of designs produced is shown to exhibit balance, orthogonality and adjusted orthogonality. The efficiencies of these designs are investigated in detail, and they are shown to be very high, and possibly maximal in some cases. 相似文献

Plant investment decisions are frequently crowded with folk-lore, even though basic economics may provide a ready guide to optimum capacity.Increasing emphasis on corporate accountability is producing the need to accept a more numerate approach to business decision taking while the overall scope for off-the-cuff decisions is rapidly diminishing. One important area of business decision taking concerns plant investment and in this paper an approximation routine is outlined for determining by economic analysis the optimum plant size for new ventures. Attention is also drawn to the importance of organization structure for investment planning. 相似文献
