The efficacy of inpatient hospitalization on emotionally impaired adolescents was investigated using present and past MMPI data. The results indicated that there is a flattening of the profile toward normalcy from time of admission to discharge time. Further statistical analysis revealed that of the 9 clinical MMPI scales, the Depression scale showed greatest change toward improvement.Received Ph.D. from the State University of New York at Stony Brook.

The present study employed multilevel random-effects regression analyses to model individual and community correlates of youth supplying tobacco to other minors. Data from 8486 youth in 40 Midwestern junior high and high schools were examined. Results indicate community support for tobacco-possession laws was associated with lower likelihood of youth supplying tobacco to minors. Individual attitudes supporting tobacco possession laws were also associated with lower likelihood of supplying tobacco. Recent smoking, using a social source or purchasing tobacco in the past month, successfully purchasing tobacco during the last attempt to buy it, and having friends who use tobacco were associated with an increased likelihood of supplying tobacco to minors. Results also suggest that purchasing tobacco in the past month or being successful during the last attempt to buy it dramatically increase the odds of supplying tobacco among Never and Past Smokers. Implications of these findings are presented.

It is well known that those with higher SES characteristics tend to vote at higher rates in U.S. elections. Over the past several decades many proponents of eased voter registration requirements have predicted that liberalizing voter registration laws will significantly improve turnout, especially among the least well- educated and the poor. In this article we offer a rational choice model of turnout that leads us to expect the greatest turnout gains from virtually eliminating voter registration costs will instead accrue to those with medium income and education. We test this prediction longitudinally over the period 1972–1992 using a vast survey and a natural experiment comparing voters in states that adopted election day registration (EDR) with those residing in states maintaining more traditional closing dates. Contrary to much of the literature, citizens with medium education and medium income voted more under EDR, as the model predicts. We conclude that the methods used here better capture and empirically identify the curvilinear relationship between voter registration laws and the turnout probabilities at various SES levels. 相似文献
