Contextual Stress and Health Risk Behaviors Among African American Adolescents

This study examined the longitudinal association between contextual stress and health risk behaviors and the role of protective factors in a community epidemiologically-defined sample of urban African American adolescents (N = 500; 46.4% female). Structural equation modeling was used to create a latent variable measuring contextual stress (community violence, neighborhood disorder, and experiences with racial discrimination). Contextual stress in 8th grade was associated with aggressive behavior and substance use 2 years later for boys. For girls, contextual stress predicted later substance use, but not aggressive behavior. High academic competence and self-worth reduced the impact of contextual stress on substance use for boys. Implications for intervention and directions for future research on health risk behaviors among African American adolescents are discussed.     

Field testing of collection cards for Cannabis sativa samples with a single hexanucleotide DNA marker

The validity and feasibility of using DNA collection cards in the field for preservation and analysis of Cannabis sativa genotypes were investigated using a highly specific hexanucleotide marker. Collection cards were submitted to the National Marijuana Initiative, which selectively trained and managed the collection of specific types of samples from a variety of participating agencies. Samples collected at seizure sites included fresh marijuana leaf samples, dried "dispensary" samples, U.S. border seizures, and hashish. Using a standardized PCR kit with custom-labeled oligonucleotide primers specific to marijuana, collection cards produced eight genotypes and 13 different alleles, extremely low baselines, and no cross-reactivity with control plant species. Results were produced from all sample types with the exception of hashish. Plant DNA collection cards represent an easily implementable method for the genetic identification and relatedness of C. sativa street and grow site-seized samples with applications for databasing and market disruption.     

Probation/Parole Officer Psychological Well-Being: the Impact of Supervising Persons with Mental Health Needs

Although supervising persons with mental illness can pose special challenges for community parole/probation officers (PPOs), few studies have investigated whether the number of supervisees on an officer’s caseload increases risk for poor mental health for PPOs and whether this link is due to emotional exhaustion. Using statewide survey data from 798 PPOs, we examine whether the number of supervisees on an officer’s caseload with mental health problems is associated with depressive symptoms reported the PPOs and whether this relationship is mediated by emotional exhaustion. In addition, we evaluate the potential mitigating role of both mental health services received by supervisees and officer training in mental health in the relationship between the number of supervisees on an officer’s caseload with mental health problems and emotional exhaustion experienced by PPOs. Findings reveal that PPOs with more supervisees on their caseload report significantly higher levels of depressive symptoms and that this relationship is completely explained away by emotional exhaustion. Neither mental health services received by supervisees nor officer training in mental health mitigated the link between the number of supervisees on an officer’s caseload with mental health problems and officer emotional exhaustion. This study underscores the importance of the psychological well-being of those on parole/probation for the emotional and mental health of the officers who supervise them.     

The Impact of Socio-Political Integration and Press Freedom on Corruption

The analyses in this study demonstrate a more nuanced understanding of a previously understood phenomenon – that openness has a negative relationship with corruption. It is argued that this relationship is substantially influenced by the domestic context, a relationship that has been underdeveloped by previous empirical studies. Focusing on social and political integration, I find that the effect of openness on corruption is conditioned by domestic institutions. The empirical evidence suggests that while political and social openness have a significant impact in combating corruption given a free press, the impact of such international forces are negligible in cases where press freedoms are low.     

The EU and Russia's conflicting regime preferences in Ukraine: assessing regime promotion strategies in the scope of the Ukraine crisis

This paper evaluates the competitiveness of the European Union (EU) and Russia's regime preferences in their foreign policies towards Ukraine in the scope of the on-going Ukraine crisis. It is argued that the underpinning geopolitical environment Ukraine currently resides in, wedged between two much larger powers (the EU and Russia), renders it a vulnerable target state for regime promotion from both sides. Indeed, since the 2004 Orange revolution in Ukraine, both the EU and Russia have had discernible regime promotion strategies in their foreign policies. The EU's regime promotion has focussed on facilitating democracy in Ukraine, along with more material interests (trade and strategic aims) while Russia has reacted with increasingly zero-sum policies which pursue its preference for having a loyal and Russian-facing regime in Ukraine. Ultimately, the increasing competitiveness of the EU and Russia has been a key factor in the onset of the Ukraine crisis, which offers important insight into the relationship between large powers and the smaller third states which lie in their overlapping spheres of influence.
