The purpose of this study was to determine the extent to which multiple health and lifestyle variables differ among 406 adolescent males classified according to average duration of daily television viewing. Cattell's 16PF Questionnaire, Form C, and Rosenberg's Self-Esteem Scale were employed to assess psychological health, and the Physical Performance Test for California was used to measure six dimensions of physical fitness. Participants also completed a questionnaire requesting general demographic data, and information regarding lifestyle and average amount of time spent watching television per day. Results indicated that the well-being of the boys was related significantly to the extent of television viewing. Light television viewers were more physically fit, emotionally stable, sensitive, imaginative, outgoing, physically active, self-controlled, intelligent, moralistic, college bound, church oriented, and self-confident than their counterparts, especially heavy television viewers. Furthermore, light television viewers were less troubled, frustrated, and shrewd, and used drugs less frequently, particularly alcohol, than moderate and heavy television watchers, especially the latter.Larry Tucker, Associate Professor, received his Ph.D. from Southern Illinois University-Carbondale in Health Education. His research interests include adolescent health behavior, particularly self-destructive behaviors and achieving high-level wellness.  相似文献

Numerous studies have established a strong connection between the use of illicit drugs and the commission of other illegal activities, including both predatory and property crimes. No study, however, has examined the cost of crimes associated with drug users both as victims and as perpetrators. In the present study, recent data were analyzed from a targeted sample of chronic drug users (CDUs) and a matched sample of non-drug users (NDUs) in Miami-Dade County, Florida, to estimate the incremental cost of crime associated with CDU. Two separate models were employed to estimate (1) the probability of being a victim or a perpetrator of crime and (2) the cost of crime for both situations. The cost measures were transformed to reduce the influence of extreme outliers, and a smearing technique was used to compare the cost of crime for CDUs relative to NDUs. The findings illustrate that criminal activity among CDUs is circular, extensive, and costly. Implications for law enforcement, criminal justice policy, and substance abuse treatment are discussed.  相似文献

Katz and King have previously proposed a statistical model formultiparty election data. They argue that ordinary least-squares(OLS) regression is inappropriate when the dependent variablemeasures the share of the vote going to each party, and theyrecommend a superior technique. Regrettably, the Katz–Kingmodel requires a high level of statistical expertise and iscomputationally demanding for more than three political parties.We offer a sophisticated yet convenient alternative that involvesseemingly unrelated regression (SUR). SUR is nearly as easyto use as OLS yet performs as well as the Katz–King modelin predicting the distribution of votes and the compositionof parliament. Moreover, it scales easily to an arbitrarilylarge number of parties. The model has been incorporated intoClarify, a statistical suite that is available free on the Internet.  相似文献
