During first semester 1980, 96 first and last year male police students and 166 law students were surveyed about their drug use patterns and attitudes towards alcohol. Of these students, 69.3 percent drank at least once a month, 80.7 percent used coffee or tea, 23.6 percent analgesics, 3 percent antihistamines and marijuana and less than 1 percent sedatives, tranquilizers, stimulants, hallucinogens, cocaine or opiates once a month or more. Law students used caffeine and marijuana significantly more frequently than police students. On the whole, there were more similarities than differences between the two groups in terms of drug consumption. In terms of attitudes, police students felt significantly more than law students that alcoholism was caused by moral weakness and medical illness as shown in the Attitude Towards Alcoholism questionnaire. But significantly more police students (82 percent) than law students (37 percent) felt that it was important to have drug and alcohol education as part of their course of study. Also significantly more police students (58 percent) than law students (24 percent) felt that they were prepared to manage drug or alcohol problems professionally. 相似文献

In this study, we analyze the voting records of U.S. senators on three recent international trade bills. Our objective is to assess the importance of ideology and constituent interest as forces that influence protectionist vs. free trade voting behavior. The methodology uses discriminant analysis supplemented with expert judgement. The first conclusion is that ideology is the more important force in generic protectionism issues, and local constituent interests are more important for commodity-specific issues. Second, we find that protectionism is especially associated with liberal ideology, high import impact, and low export dependence. Although the discriminant analysis outperforms expert judgement in classifying protectionist vs. free trade votes in two of the three bills studied, the best explanation is obtained by using both methods together.We are indebted to Dennis Quinn, Tom Brewer, Michael Czinkota, Karen Gaertner, Annette Shelby, and Melanie Hayes. Errors remain our responsibility. 相似文献

A longitudinal study of 114 women, all having serious problems in intimate relationships, recruited from the community was undertaken in order to investigate relationship and battering status over time. In the original sample (N=193), 97 women were battered and 96 were not battered, as determined by an adaptation of the Conflict Tactics Scale. Of the 114 who returned approximately 2 and 1/2 years later, only 25% of the 51 originally battered women were still in that category. Discriminant function analysis using a combination of variables from established instruments (depression, self-esteem, physical symptoms, self-care agency) and in depth interview (education, relationship control, relationship duration, childhood abuse) failed to distinguish those battered from those not abused at Time 2. Results do not support a learned helplessness model for most women experiencing abuse, and they suggest that battered women seen in the health care and/or social services systems should be supported in a process of healthy decision making about their relationship status. 相似文献
