This exploratory study examines relationships between the police and Hispanics in Texas. Specifically, data were collected on Hispanic evaluations of police performance, expectations of police performance, and overall satisfaction with the police. A sample of 500 Hispanics throughout the state of Texas were surveyed on their experienced and perceived relationships with three levels of police agencies: local (municipal) police, sheriff's officers, and the state's Department of Public Safety. Findings are reported based upon overall ratings of the police, victim-related data, and data from individuals who had any form of contact with the police. Significant findings show that any form of contact with the police appeared to lower the rating of police performance. This appears to be a product of the interaction between high public expectations and qualitatively poor police performance. Further findings indicate that an increase in the fear of crime among Hispanics lowered evaluations of local police. Similarly, victimization lowered the evaluation of local police, the county sheriff, and the Department of Public Safety. Hispanics also perceived that officers have a “bad attitude,” that the police need to patrol and investigate more, that response time should be improved, and that there should be less discrimination against Hispanics. These findings appear to be largely influenced by ineffective communication (both symbolic and linguistic) and cultural conflict.  相似文献

Results are presented of a self-administered questionnaire completed by 201 youthful hallucinogen users. It was found that 55.5% of the population experienced at least one bad trip, although not one of these 111 subjects sought medical help. Investigation of the subject's family, drug-use pattern, mood, and environment revealed no clear-cut predisposing factors toward an adverse drug experience. While a significant correlation existed between a high level of cigarette consumption and a certain type of drug user, the number of different drugs used by the subjects was the only variable which positively correlated with the occurrence of a bad trip. Multiple stepwise regression indicated that over the period from 1965 to 1973 a change has taken place in the sample studied, such that today a young person introduced to hallucinogens is likely to take a greater number of drugs and is more likely to experience a bad trip than was his chronological conterpart of 1965.M.D. 1955 and Med.
