Going To Bat: Assessing Disgust Sensitivity And Related Factors In Behavioral Avoidance, Molly E. Wickenhauser Jan 2019

Going To Bat: Assessing Disgust Sensitivity And Related Factors In Behavioral Avoidance, Molly E. Wickenhauser

Electronic Theses and Dissertations

The present study used archival data (N = 194) consisting of responses from a battery of questionnaires and data from eight behavioral avoidance tasks (BATs). Correlational analyses demonstrated that disgust sensitivity, anxiety sensitivity, state disgust and anxiety ratings during BATs, and behavioral avoidance on BATs were significantly correlated. Higher disgust sensitivity and behavioral avoidance was also associated with being female. Unexpectedly, emotion dysregulation was not correlated with disgust sensitivity or behavioral avoidance. Next, a series of hierarchical multiple linear regressions indicated that the contamination disgust domain appeared to be the strongest predictor of behavioral avoidance on core- and contamination-related BATs, …

Innovation, Ceos, And Ipos, Zhilu Lin

Electronic Theses and Dissertations

In Part 1, I study if CEOs with innovative ability impose a cost upon their firms. I find that while there is a positive effect of a CEO’s innovative ability on firm innovation, the benefit is only when CEO’s innovative ability is useful for the firm. Further, firms with innovator CEOs spend more on R&D projects but with lower efficiency and hold more cash but with lower cash value compared to firms with non-innovator CEOs. These results suggest that innovator CEOs create an overinvestment problem. In Part 2, I study the effects of talent cycling on IPO long-run performance and …

Allodynia And Self-Efficacy In Migraineurs, Ashley N. Polk Jan 2019

Allodynia And Self-Efficacy In Migraineurs, Ashley N. Polk

Electronic Theses and Dissertations

Headache disorders are among the most comdisorders of the nervous system, with migraine alone affecting 14% of women and 6% of men worldwide each year. Headache-related self-efficacy, or one’s confidence in preventing and managing headache, is particularly important for prevention and management of headache disorders and predicts response to behavioral and pharmacological treatments. Allodynia, the perception of non-noxious stimuli as painful due to central sensitization, compounds headache-related disability and compromises efficacy of triptans. Therefore, migraineurs with allodynia may perceive headache treatments as less efficacious and thus have reduced perceived headache-related self-efficacy. However, no literature to date has explored the relationship …
