Dunc13 Isoforms, Rim, And Rab3 Differentially Modulate Ethanol Sedation Sensitivity In Drosophila Melanogaster., Gaurav Shrestha

Electronic Theses and Dissertations

Dunc13 is a Drosophila active zone protein homologous to the mammalian Munc13that interacts with RIM and Rab3 as a heterotrimer. Alcohol binds to the C1 domain of Dunc13/Munc13 and inhibits its ability to bind to Diacylglycerol, inhibiting neuronal signaling. The genetic reduction of Dunc13 activity in the Dunc13P84200/+ heterozygotes induces a state in flies that mimics alcohol tolerance, evidenced by increased self-administration, and behavioral, physiological, and molecular resistance. This includes changes in the expression of key synaptic proteins, such as decreased expression of Dunc13 and Syb mRNA, and increased expression of Rim and Rab3 4hrs after ethanol exposure. Dunc13 has …

The Effect Of A Scarcity Mindset On External Auditors' Reliance On The Internal Audit Function, Brett Patterson

Electronic Theses and Dissertations

Audit regulators are concerned that times of economic uncertainty will likely cause external auditors to misuse the work of the internal audit function (IAF). These concerns are consistent with prior psychology research finding that objective poverty or a subjective, perceived lack of resources induces a scarcity mindset, which then leads to counterproductive economic behaviors. Therefore, I examine the effect of such a scarcity mindset on external auditors’ IAF reliance choices. In an experiment that incorporates a setting mimicking the evidence collection process, I manipulate the external auditor’s scarcity mindset and the internal audit function’s competence. I find that external auditors …

Temperamental Fear As A Vulnerability Factor For Posttraumatic Stress Symptoms: An Examination Of Fight, Flight, Freeze Using A Trauma Film Paradigm, Jaime P. Murtagh

Electronic Theses and Dissertations

Fear is often the primary emotion associated with anxiety and stress-related disorders with research suggesting that the expression of fear varies greatly between individuals and has been hypothesized to be associated with differences in behavioral inhibition, personality, as well as temperament. One theory which has been used to conceptualize variations in temperament is the reinforcement sensitivity theory which consists of the behavioral inhibition system (BIS), behavioral approach system (BAS), and the fight, flight, freeze system (FFFS), with the latter being of particular interest in posttraumatic stress disorder (PTSD). Variations in FFFS sensitivity has been linked to variations in psychopathology with …

Weight Discrimination And The Negative Cultural Value Of Fat: The Relationship To Well-Being Across Higher Weight Individuals Of Different Nations, Ana Clara Vieira Zaidan

Electronic Theses and Dissertations

Discrimination against individuals with higher body weights is prevalent in and outside of the US (see Pearl et al., 2021), yet research on this topic is limited when considering non-US perspectives. Cross-cultural studies had not yet explored the impact of cultural norms around weight. In the domain of anti-fat attitudes, cross-cultural research had explored variations in the negative cultural value of fatness (NCF) and its impacts across countries (Crandall et al., 2001). Incorporating this perspective, Study 1 examined how perceived weight discrimination (PWD) and NCF uniquely predict various well-being outcomes across two different countries among individuals who identified as overweight. …
