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

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 …
