Studies have repeatedly shown that members of minority groups are likely to hold less favorable perceptions of the police than their white counterparts. Relying on a unique sample of nearly 70 Hispanic immigrants, this study expands current knowledge on correlates of Hispanics’ perceptions of police. Overall, findings of this study indicate Hispanic immigrants of Mexican descent generally hold favorable views of the police. Results also suggest, however, that those who came to the US through illegal channels are significantly less likely to hold positive perceptions of police than those who relocated through legal channels. Furthermore, a preliminary analysis to assess the level of understanding that Hispanic immigrants have of police, including their role and function in American society, was conducted. Findings indicate there is a high level of misunderstanding concerning police services among this population. Based on our results, we discuss policy implications and future directions for research. 相似文献

Fifty-three head hair specimens were collected from 38 males with a history of cannabis use documented by questionnaire, urinalysis and controlled, double blind administration of delta9-tetrahydrocannabinol (THC) in an institutional review board approved protocol. The subjects completed a questionnaire indicating daily cannabis use (N=18) or non-daily use, i.e. one to five cannabis cigarettes per week (N=20). Drug use was also documented by a positive cannabinoid urinalysis, a hair specimen was collected from each subject and they were admitted to a closed research unit. Additional hair specimens were collected following smoking of two 2.7% THC cigarettes (N=13) or multiple oral doses totaling 116 mg THC (N=2). Cannabinoid concentrations in all hair specimens were determined by ELISA and GCMSMS. Pre- and post-dose detection rates did not differ statistically, therefore, all 53 specimens were considered as one group for further comparisons. Nineteen specimens (36%) had no detectable THC or 11-nor-9-carboxy-THC (THCCOOH) at the GCMSMS limits of quantification (LOQ) of 1.0 and 0.1 pg/mg hair, respectively. Two specimens (3.8%) had measurable THC only, 14 (26%) THCCOOH only, and 18 (34%) both cannabinoids. Detection rates were significantly different (p<0.05, Fishers' exact test) between daily cannabis users (85%) and non-daily users (52%). There was no difference in detection rates between African-American and Caucasian subjects (p>0.3, Fisher's exact test). For specimens with detectable cannabinoids, concentrations ranged from 3.4 to >100 pg THC/mg and 0.10 to 7.3 pg THCCOOH/mg hair. THC and THCCOOH concentrations were positively correlated (r=0.38, p<0.01, Pearson's product moment correlation). Using an immunoassay cutoff concentration of 5 pg THC equiv./mg hair, 83% of specimens that screened positive were confirmed by GCMSMS at a cutoff concentration of 0.1 pg THCCOOH/mg hair. 相似文献

This article explores the legal implications of pay for performance programs from the perspective of healthcare providers. The author provides an informative background on the emergence of pay for performance programs and examines the structure and operation of these programs. She then explores the liability issues of health plans and managed care organizations and delves into evidentiary issues related to pay for performance information. Her article concludes with some practical suggestions for providers in preparing for an expansion of these quality initiatives. 相似文献
