Emotionally And Socially Aware Approaches To Understanding And Changing Users’ Cybersecurity Behavior, Michael Fagan

Doctoral Dissertations

Security is a priority to most, but studies show that users commonly fail to adopt recommended cybersecurity behavior. Researchers have looked to user factors for explanations of this gap, finding security and convenience to be common considerations, along with perceptions of risks and past experiences. Some have tried to alter user behavior, but are targeted at specific advice and focused on rational motivations to persuade users.

In this thesis, three expertly recommended cybersecurity advice (i.e., updating software regularly, using two-factor authentication, using a secure password manager) are deeply explored. These results inform the design of videos in a systematic study …

An Evaluation Of Traffic Control Devices And Driver Distraction On Driver Behavior At Railway-Highway Grade Crossings, Radhameris A. Gomez Gabriel

Doctoral Dissertations

At-grade crossings (grade crossings) are those crossings in which any part of a roadway intersects with railroad tracks. Safety at these railroad-highway grade crossings is a major concern, with traffic control warning devices serving as the main mechanisms for improving safety. There are three factors that influence a driver’s behavior at a given crossing. First, traffic control devices, including warning devices at the railroad-highway grade crossings, provide the driver with information whose impact will depend in part on the likelihood that the driver knows whether to glance in the direction of the device based on prior experience, and in part …

Impacting Student Slumber: An Analysis Of Self-Report And Physiological Data Following A Psychoeducational Intervention, Danielle N. Newman

Doctoral Dissertations

Research shows that college students have extensive rates of sleep struggles, with up to 89% of college students reporting that they have moderate to severe difficulties with sleep (Buboltz, Brown, & Soper, 2001). Insufficient sleep has been linked to problems with academics (Kelly, Kelly, & Clanton, 2001; Taylor, Vatthauer, Bramoweth, Ruggero, & Roane, 2013), mental health (Ghumman & Barnes, 2013; Home, 1993; Manber & Chambers, 2009), physical health (Dahl & Lewin, 2002; Gailliot et al., 2007; Lyytikainen, Rahkonen, Lahelma, & Lallukka, 2011; Van Cauter, Leproult, & Plat, 2000), and a variety of other problems. Results pertaining to the suggested and …

The Development And Validation Of An Automatic-Item Generation Measure Of Cognitive Ability, Scott Hines

Doctoral Dissertations

Cognitive ability is perhaps the most studied individual difference available to researchers, being measured quickly and effectively while demonstrating a predictable influence on many life outcomes. Historically, the evolution of the psychometric study of cognitive abilities has pivoted on the development of new and better methodologies allowing for a more complete and efficient capture of intellect. For instance, recent advances in computer and Internet technology have largely replaced traditional pencil-and-paper methods, allowing for innovative item development and presentation. However, concerns regarding the potential adverse impact and test security of online measures of cognitive ability, particularly in unproctored situations, are well …

Personal Intelligence And Learning About Personality In Everyday Life, Jayne L. Allen

Doctoral Dissertations

As we encounter other people, we form impressions of and judgments about them. Based on these evaluations, we choose whether we want to interact any further, and if we do, what type of relationship we want to have. Although such choices can have far-reaching consequences, we typically base them on tacit knowledge. Our abilities to reason about our own and others’ personalities—abilities theorized to be part of a personal intelligence (Mayer, 2008)—determine in part the relationship outcomes we experience.

The existence of such an intelligence implies that people have a “database” they consult when making personality-relevant decisions. This raises the …

The Mediating Influence Of Career Aspirations And Career Decision-Making Self-Efficacy On Self-Differentiation, Vocational Identity, And Career Indecision, Jay Justin Middleton

Doctoral Dissertations

Research indicates that numerous family variables influence the career-development process (Osipow, 1983). Bowen's family systems theory is one model through which to view the development and influence of the family on career development (Bowen, 1972). According to his theory, individuals begin life highly dependent on family members for all forms of support. As people grow into adults, they slowly become independent of their family, or self-differentiated. Adults low in self-differentiation have been found to make decisions in order to appease their families. Further, low levels of self-differentiation have been related to greater mental health problems (Skowron & Friedlander, 1998) and …
