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.     

Application of a pyroprobe to simulate smoking and metabolic degradation of abused drugs through analytical pyrolysis

Smoking of illicit drugs can produce unique metabolic biomarkers. Smoking conditions can be partially modeled via pyrolysis, a process that decomposes a chemical compound by extreme heat. Pyrolytic decomposition was found to be useful as a limited metabolic mimic in that analytical pyrolysis can be used to generate some of the same compounds produced by metabolic degradation. This project focused on the pyrolysis of cocaine and methamphetamine using a pyroprobe coupled with a GC/MS and more generally, potential applications of pyrolysis to forensic toxicology. Common diluents including lidocaine, caffeine, and benzocaine were pyrolyzed in mixtures with cocaine and methamphetamine. Correlations between pyrolytic and metabolic degradations revealed that this method has the capability to produce some of the reported metabolites such as norcocaine and cocaethylene for cocaine, and amphetamine for methamphetamine. The results demonstrate that analytical pyrolysis has the potential to identify some metabolic products and to supplement in vivo and enzymatic studies.     

The Impact of Intimate Partner Violence on Mothers’ Parenting Practices for Urban, Low-Income Adolescents

This study examined whether depression and social support mediated the relationship between intimate partner violence (IPV) and parenting practices. Participants were 1,057 female primary caregiver-young adolescent pairs. (Sample included greater than 90?% biological mothers; hereafter, female primary caregivers are referred to as mother.) Findings indicated that IPV was associated positively with mothers’ use of physical punishment and negatively with mothers’ involvement in their children’s education. Although depression and social support were not found to mediate the relationship between IPV and parenting practices, study findings suggest that IPV directly and negatively impacted mothers’ parenting practices. In sum, findings point to the important role that IPV may play in explaining parenting practices for mothers living in high-risk urban environments.
