The authors investigated relationships between marijuana and inhalant use and several cultural and demographic factors in Anglo American and Hispanic American adolescents (N=1,094). Outcome measures assessed lifetime and 30-day marijuana and inhalant use. Predictors and covariates used in logistic regression analyses were region, grade, gender, knowledge, acculturation, familism, and parental monitoring. Hispanic Americans exhibited higher usage across all measures. In this group, high acculturation was associated with low marijuana, but high inhalant, use. Across all participants, positive family relations and parental monitoring were strongly associated with attenuated marijuana use hut only among those most knowledgeable about drugs. Familism and monitoring were not associated with diminished usage among the less knowledgeable. For inhalants, monitoring combined with high knowledge or high familism was associated with diminished usage.

Incorporating three analytic approaches, the present research examines HIV/AIDS awareness levels in a sample of Native American and Anglo parents and children. Descriptive analysis revealed that Native Americans, especially children, possess startlingly poor levels of HIV/AIDS-related knowledge compared with Anglos. This disparity is most evident for more subtle HIV/AIDS facts. Using an all-or-none scoring model disclosed even larger ethnic discrepancies. Multiple regression analysis demonstrated that fatalism and family communication mediate the HIV/AIDS awareness-ethnicity relationship beyond the effects of socioeconomic status.

Using uniform crime statistics, this research investigates the impact of California's three‐strikes law on instrumental, violent, minor, and drug‐related crimes over the first 5 years of the law's implementation. Autoregressive integrated moving average (ARIMA) models reveal little immediate impact of the law, but significant effects on instrumental crime over time, suggesting an incapacitation effect. After correcting for autocorrelation distortions, less restrictive multiple regression models that test simultaneously for immediate and gradual intervention effects disclose immediate (deterrent) effects on instrumental and minor crimes and arrests, and long‐term (incapacitation) effects on these and violent crimes as well. Drug‐related crimes appear impervious to the three‐strikes law under any analytic model, suggesting the unresponsiveness of such crimes to increasingly severe legal sanctions.
