Electronic Theses and Dissertations, 2020-
With the growing use of Online social media (OSM), users are observing a substantial amount of information in their social feeds. Moreover, people often use multiple OSM platforms because of each platform's unique features. Because of the huge volume of information present in social feeds, it restricts a user's ability to process the relevant information since the most important information may be overwhelmed by unimportant information. For information to diffuse in OSM, the receiver's attention is the most important condition. Cognition plays an important role in determining a user's attention/responsiveness. If OSM users receive the information above their cognition limits …
Not All Influence Is Born Equal: On The Effects Of Various Types Of Behavioral Influence Relationships On Social Media, 2022 University of Central Florida
Not All Influence Is Born Equal: On The Effects Of Various Types Of Behavioral Influence Relationships On Social Media, Chathurani Senevirathna
Electronic Theses and Dissertations, 2020-
Typically, online social influence is analyzed using a single metric approach. However, social influence is not monolithic; different users exercise different influences in different ways, and influence is correlated with the user and content-specific attributes. One such attribute could be whether the action is an initiation of a new post, a contribution to a post, or a sharing of an existing post. Thus, this dissertation uses this platform-independent action classification and models the influence as multiple entities and examines social networks through the perspective of behavioral influence propagation. Two empirical studies are present in this dissertation. The first study presents …

Evaluating Mixed Reality Training For Calibrating Operators’ Mental Models Of Advanced Driver Assistance Systems, 2022 Florida Institute of Technology
Evaluating Mixed Reality Training For Calibrating Operators’ Mental Models Of Advanced Driver Assistance Systems, Ganesh Pai Mangalore
Link Foundation Modeling, Simulation and Training Fellowship Reports
Advanced Driver Assistance Systems (ADAS) offer safety benefits by handling active driving tasks. However, due to limited operational design domain, these systems may require driver intervention, making drivers’ mental models about system limitations and capabilities an important factor when operating them. Literature suggests most drivers are uninformed or unaware of their systems (McDonald et al, 2018), lacking complete or accurate mental models. Mental models (MM) are described as reflections of operators’ knowledge of system’s purpose and various functioning states (Seppelt & Victor, 2020). Incomplete MM of systems’ limitations may also adversely affect drivers’ hazard avoidance behavior.
