Adolescents’ time use: Effects on substance use,delinquency and sexual activity

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.

Campaign Advertising in Taiwanese Presidential Elections

Campaign advertising in Taiwan, particularly at the presidential level, has increased in importance as the political and media contexts in which campaigns are fought has evolved. To further our understanding of this increasingly prevalent campaign tool, the article analyses a large number of television and newspaper advertisements for six presidential candidates across three campaigns. Extending prior research on Taiwan the analysis incorporates three dimensions of campaign advertising: the distribution, composition and tone of appeals. The findings suggest that, for better or worse, many elements of broader political competition in Taiwan are equally present in candidates' campaign advertising.     

Increasing Community College Completion Rates Among Low-Income Students: Evidence from a Randomized Controlled Trial Evaluation of a Case-Management Intervention

Community college completion rates are low, especially among low-income students. The existing policy and research attention has primarily focused on academic and financial challenges, but there is ample reason to think that non-academic obstacles might be key drivers of dropout rates for low-income students. This study focuses on the role of “life barriers” and investigates the effectiveness of intensive case-management services for low-income community college students. We evaluate the impact of the Stay the Course (STC) intensive case-management program through a multi-armed randomized controlled trial evaluation conducted between 2013 and 2016 in Fort Worth, Texas. Analysis of administrative records indicates that STC significantly increased persistence and degree completion for women; estimates for the full sample are imprecise. The statistically significant estimates for women imply that STC tripled associate's degree receipt by 31.5 percentage points. We find no difference in outcomes between students in an emergency financial assistance (EFA) only treatment arm and the control group. Given program costs of $4,343 per person, the implied cost per additional associate's degree is $27,140. This study complements existing literature on financial and informational interventions designed to increase completion rates and is most closely related to the smaller literature examining coaching and mentoring interventions.
