Can You Get Beliefs From Retweets? An Examination Of The Extended Parallel Processing Model On Social Media, Xialing Lin

Masters Theses

The Extended Parallel Processing Model (EPPM; Witte, 1992) has been applied as a framework to examine risk information dissemination and effective sensation seeking in various health communication scenarios. Previous studies suggest that it is worth examining whether Twitter could have potential efficacy effects similar to face-to-face interaction or traditional media interventions. Given the overload and discrete information in the medium environment, people would adapt information processing short cuts, to tend to similar perceptions from various sources rather than reading specific messages.

The current study investigates the threat appeal perceptions of EPPM on system-generated and other-generated message cues in social media. …

The Role Of Saturated Fatty Acids In Connexin Expression On Endothelial Cells And Eosinophils, Kurt Anthony Ashack

Masters Theses

Eotaxin is a potent chemoattractant for eosinophils that becomes elevated in the tissues in response to inflammation and increased adiposity. Therefore, eosinophil migration into adipose tissue should increase in diet-induced obese individuals, yet it does not. This suggested to us that something within the cellular microenvironment of diet-induced obese individuals might be altering the endothelial leukocyte adhesion molecules (ELAM) such as VCAM-1 or selectins on the endothelial cells, thus preventing eosinophils from entering the inflamed tissue. Connexons are gap junctions in endothelial cells and on immune cells such as macrophages that are composed of connexins and have been shown to …
