The relative influence of peer and parental influence on youths' use of alcohol and other drugs is explored among 446 Anglo and Hispanic youths, ages 9–17. Current users and abstainers are similar in age and gender. Among both groups, parental influence is more profound than that of peers. However, substance users, compared to abstainers, are more influenced by peers. Level of marijuana use by youths' friends is the most reliable predictor of drug use. Youths having viable relationships with parents are less involved with drugs and less influenced by drug-oriented peers.Funded by a grant (A-003-2) from the California Department of Alcohol and Drug Programs, R. H. Coombs, principal investigator.Research interests include comparative socialization patterns of adolescents and young adults in substance abuse vs. conventional careers.Research interests include domestic violence, child abuse, and substance abuse.Research interests include family interaction patterns, cross-cultural differences, and substance abuse prevention and treatment. 相似文献

The relationship between society, medicine, and the law is multi-faceted and complex. This Article examines the process of, and the influences on, the construction of fetal personhood in the legal discourses in American and Commonwealth case law and statutes. It demonstrates how the physical and visual separation of the fetus, as made possible by medical advances, has influenced the development of legal doctrine relating to the rights of the fetus. 相似文献

Validation of the use of a commercially available kit for the identification of prostate specific antigen (PSA) in semen stains 总被引:1,自引:0,他引:1

PSA is currently being used to detect and monitor quantitatively the development of prostate cancer by serum levels of PSA and has also been found to be present in high concentrations in semen. Elegantly simple, sensitive, and reproducible methods have been developed for analysis of the presence of PSA, including the Tandem-E PSA Immunoenzymetric Assay. The most common procedures for the forensic identification of semen have focused on the microscopic detection of sperm, acid phosphatase activity, and immunoelectrophoretic methods for the detection of PSA. Although these methods have been used for many years, there are problems associated with each method. The Tandem-E PSA Immunoenzymetric Assay detected PSA in 100% of the forensic casework fabric samples, 80% of the forensic casework vaginal swabs and 100% of the vasectomized individuals tested. The cut-off value was determined to be 1.77 ng/mL. These results indicate that this method can be used to identify the presence of semen in forensically significant specimens. 相似文献

In a prior article in this journal, John Nyman argues that the effect on health care use and spending found in the RAND Health Insurance Experiment is an artifact of greater voluntary attrition in the cost-sharing plans relative to the free care plan. Specifically, he speculates that those in the cost-sharing plans, when faced with a hospitalization, withdrew. His argument is implausible because (1) families facing a hospitalization would be worse off financially by withdrawing; (2) a large number of observational studies find a similar effect of cost sharing on use; (3) those who left did not differ in their utilization prior to leaving; (4) if there had been no attrition and cost sharing did not reduce hospitalization rates, each adult in each family that withdrew would have had to have been hospitalized once each year for the duration of time they would otherwise have been in the experiment, an implausibly high rate; (5) there are benign explanations for the higher attrition in the cost-sharing plans. Finally, we obtained follow-up health-status data on the great majority of those who left prematurely. We found the health-status findings were insensitive to the inclusion of the attrition cases. 相似文献
