Since 1972, the United States Parole Commission has used an actuarial device as an aid in assessing parole prognosis in conjunction with explicit decision guildelines. This article describes the most recent revision of the actuarial device used by the commission. This device (SFS 81) is examined and compared with the device previously used (SFS 76) on five dimensions: validity, stability, reliability, simplicity, and ethical concerns.  相似文献

Despite long concern in the United States over alcohol consumption by adolescents and problems associated with drinking among Native Americans, few studies have dealt with the functions of drinking for Native American and White youth. The findings presented here are based on responses to a self-report questionnaire administered to ninth- through twelfth-grade students at two high schools in Fremont County, Wyoming — the county where the great majority of Wyoming's Native American population resides. Based on work by Jessor, Carman and Grossman, 30 items concerning positive-social, personal-effect, and experiential reasons for drinking were examined. Although there are some statistically significant differences in responses to individual items and statistically significant differences between Indian and White males and females on the Personal-Effect and Positive-Social categories of items, the functions of drinking appear to be quite similar for these Indian and White youth.Received his Ph.D. in sociology from Yale University in 1966. Current research interest is determining the impact of a heroin treatment program on the incidence and prevalence of heroin use in Cheyenne, Wyoming.  相似文献

Using an integration of social control theory and the routine activity perspective, adolescent time use was examined for effects on problem behaviors. We examined a wide variety of time use categories, including homework, extracurricular activities, sports time, alone time, paid work, housework, television watching, as well as indices of family time and peer time, for their effects on heavy alcohol use, cigarette smoking, illicit drug use, delinquency and sexual activity. The study employed a representative household sample of adolescents (n=606) and took into account important sociodemographic factors – gender, age, race (Black and White), and socioeconomic status. The most important predictors of adolescent problem behaviors were family time and peer time. Family time serves as a protective factor against all five problem behaviors while peer time is a highly significant risk factor for all five problem behaviors.
