Elite Deviance, Organized Crime, And Homicide: A Cross-National Quantitative Analysis, Carol L.S. Trent

USF Tampa Graduate Theses and Dissertations

Both elite deviance, committed by the upper echelons of society, and organized crime threaten development and the rights and security of people across and within nations; however empirical research on these topics is limited, especially in the field of criminology. This study addresses this gap in the literature by testing hypotheses derived from Simon’s symbiotic theory of elite deviance, which posits that direct and indirect relationships exist between elite deviance, organized crime, and conventional crimes exist (2008). The intervening effects of national culture and political economic ideology are also considered.

To test the research hypotheses, this study uses homicide rates, …

Individual Differences In The Dopaminergic Reward System: The Effect Of Genetic Risk On Neural Reward Sensitivity And Risky Choice, Heather E. Soder

USF Tampa Graduate Theses and Dissertations

When making decisions, individuals evaluate several possible outcomes of their choice; however, some display heightened reward sensitivity, despite the potential for future negative consequences, which can lead one to make risky choices. Rewards are processed in the mesolimbic dopamine reward system, and this system is in part modulated by genetic polymorphisms that are associated with dopamine transmission. The current study tested if genetic polymorphisms that are associated with enhanced dopamine neurotransmission will be more neurally reward sensitive, score higher on self-reported impulsivity, and make riskier choices. In a sample of 85 participants, five genetic polymorphisms were genotyped and used to …
