Factors Associated With Skin Cancer Prevention: Primary And Secondary Behaviors., Jeanne Ward May 2023

Factors Associated With Skin Cancer Prevention: Primary And Secondary Behaviors., Jeanne Ward

Electronic Theses and Dissertations

Skin cancer, seemingly more innocuous than other cancers, maintains the highest incidence among cancers in the United States. While it is treatable early, metastasized melanoma or other carcinomas present severe illness with high mortality rates and disproportionate 5-year survival rates among ethnic/racial groups. Fortunately, most skin cancer is highly treatable when found in the early stages. However, this necessitates prevention tactics to avoid the causative agent, ultraviolet radiation, and regular skin screening to catch the disease in earlier stages. Unfortunately, these tactics are not widely conducted by adults, despite substantial skin cancer awareness. Therefore, motivating people to perform these health …

The Impact Of Controlling Language And Source Similarity On Psychological Reactance, Caroline Yarbrough Jan 2023

The Impact Of Controlling Language And Source Similarity On Psychological Reactance, Caroline Yarbrough

Electronic Theses and Dissertations

Persuasive health messages are frequently advertised throughout the pandemic to decrease the spread of COVID-19 while increasing the likelihood of immunity. However, research demonstrates that persuasive health messages may be ineffective because they have the potential to elicit psychological reactance. Reactance is characterized by a state of unpleasant motivational arousal and often occurs when individuals experience or perceive threats to their freedom, and it can be evoked through controlling language (Frey et al., 2021; Grandpre et al., 2003). Additionally, research has shown that similarity is associated with liking (Cialdini & Trost 1998) and people are often more inclined to comply …

Bayesian Methods For Graphical Models With Neighborhood Selection., Sagnik Bhadury Dec 2022

Bayesian Methods For Graphical Models With Neighborhood Selection., Sagnik Bhadury

Electronic Theses and Dissertations

Graphical models determine associations between variables through the notion of conditional independence. Gaussian graphical models are a widely used class of such models, where the relationships are formalized by non-null entries of the precision matrix. However, in high-dimensional cases, covariance estimates are typically unstable. Moreover, it is natural to expect only a few significant associations to be present in many realistic applications. This necessitates the injection of sparsity techniques into the estimation method. Classical frequentist methods, like GLASSO, use penalization techniques for this purpose. Fully Bayesian methods, on the contrary, are slow because they require iteratively sampling over a quadratic …
