Methamphetamine use, self-reported violent crime, and recidivism among offenders in California who abuse substances

This study uses data from 641 state prison parolees in California to examine the associations between methamphetamine use and three measures of criminal behavior: (a) self-reported violent criminal behavior, (b) return to prison for a violent offense, and (c) return to prison for any reason during the first 12 months of parole. Methamphetamine use was significantly predictive of self-reported violent criminal behavior and general recidivism (i.e., a return to custody for any reason). However, methamphetamine use was not significantly predictive of being returned to custody for a violent offense. These trends remained even after controlling for involvement in the drug trade (i.e., sales, distribution, or manufacturing).     

Microchip-based cell lysis and DNA extraction from sperm cells for application to forensic analysis

The current backlog of casework is among the most significant challenges facing crime laboratories at this time. While the development of next-generation microchip-based technology for expedited forensic casework analysis offers one solution to this problem, this will require the adaptation of manual, large-volume, benchtop chemistry to small volume microfluidic devices. Analysis of evidentiary materials from rape kits where semen or sperm cells are commonly found represents a unique set of challenges for on-chip cell lysis and DNA extraction that must be addressed for successful application. The work presented here details the development of a microdevice capable of DNA extraction directly from sperm cells for application to the analysis of sexual assault evidence. A variety of chemical lysing agents are assessed for inclusion in the extraction protocol and a method for DNA purification from sperm cells is described. Suitability of the extracted DNA for short tandem repeat (STR) analysis is assessed and genetic profiles shown. Finally, on-chip cell lysis methods are evaluated, with results from fluorescence visualization of cell rupture and DNA extraction from an integrated cell lysis and purification with subsequent STR amplification presented. A method for on-chip cell lysis and DNA purification is described, with considerations toward inclusion in an integrated microdevice capable of both differential cell sorting and DNA extraction. The results of this work demonstrate the feasibility of incorporating microchip-based cell lysis and DNA extraction into forensic casework analysis.     

Negative Life Events and Maladaptive Behaviors Among Filipino Adolescents: an Empirical Test of the General Strain Theory

Agnew’s general strain theory has been widely tested in other countries and has received general support from most studies. To date, however, there has been limited empirical test of the theory in the Philippines. Thus, this study aims to test the core theoretical propositions of the theory that link negative life events (strains) to negative emotions that in turn encourage maladaptive behaviors or criminal coping. The study uses the Global School-based Student Health Survey (2011) data on a nationally representative sample of 5920 secondary Filipino students. In general, the results support the general strain theory: negative life events (e.g., violent experiences, discrimination, sexual harassment victimization) encourage maladaptive behaviors (i.e., suicidality, substance use, and truancy), and this link is somewhat mediated or attenuated by depression. Further, conditioning factors such as parental care and supervision, social support, and engagement in physical activities moderate the effects of negative life events and depression on maladaptive behaviors. Contrary to the theory, however, some conditioning factors intensify the effects of strain on truancy. Overall, the current findings support the theory but call for further research and theory building—delinquent acts are diverse behaviors, and thus, each may require a crime-specific model of the general strain theory.
