Work-Nonwork Goal Conflict: A Self-Regulatory Expansion Of Work Life Conflict, John Michael Mckee
Work-Nonwork Goal Conflict: A Self-Regulatory Expansion Of Work Life Conflict, John Michael Mckee
Browse all Theses and Dissertations
Current conceptualizations of work-life conflict (WLC) fail to account for additional life domains beyond that already measured for by traditional work-family conflict (WFC) measures. When conceptualized from a self-regulatory perspective, WFC can be thought of as a person's work goals conflicting with his or her family goals. This goal-based conceptualization of WLC was used within the current study in order to explore the relationship between work-nonwork goal conflict and worker well-being. Participants were guided through an on-line personal project analysis, in which they elicited goals within work and nonwork domains and then provided ratings of conflict between all work and …
Visual Search Performance In A Dynamic Environment With 3d Auditory Cues, John Paul Mcintire
Visual Search Performance In A Dynamic Environment With 3d Auditory Cues, John Paul Mcintire
Browse all Theses and Dissertations
Previous research on aurally-aided visual search has repeatedly shown a significant reduction in response times when displaying 3D auditory cues. However, the vast majority of this research has only examined searches for static (non-moving) targets in static visual environments. In the present study, visual search performance in both static and dynamic (moving) visual environments is examined with and without virtual 3D auditory cues. In both static and dynamic environments, and for all observers, visual search times were significantly reduced when auditory spatial cues were displayed. Auditory cues provided the largest benefits when the target initially appeared at farther eccentricities and …
Discrimination Across The Sectors: A Comparison Of Discrimination Trends In Private And Public Organizations, Megan K. Leasher
Discrimination Across The Sectors: A Comparison Of Discrimination Trends In Private And Public Organizations, Megan K. Leasher
Browse all Theses and Dissertations
Differences and similarities between public and private sector organizations have been hypothesized and researched for several decades (Murray, 1975). This study investigated the differences in claims of employment discrimination reported for employees within the private and public sectors. A longitudinal database of statewide discrimination claims was analyzed to determine if differences in employment discrimination patterns or levels exist between the sectors. Theoretical and practical implications are presented in addition to propositions for future research.
Parameters Affecting Mental Workload And The Number Of Simulated Ucavs That Can Be Effectively Supervised, Bryan A. Calkin

The present study investigated performance and mental workload when an operator supervises multiple UCAVs. This study focused on the parameters that affect the operator's performance during a simulated UCAV suppression of enemy air defenses (SEAD) mission, which is expected to be the primary function of the UCAV. All three manipulated factors, including the number of vehicles to be supervised, vehicle airspeed, and difficulty level of attacks (targets engaged by either a single vehicle or multiple vehicles), affected both performance and subjective mental workload measures. A performance mental workload redline was defined as the point at which accomplishment scores no longer …
Effect Of Variable Feedback Delay On Visual Target-Acquisition Performance, Julio Christian Mateo
Effect Of Variable Feedback Delay On Visual Target-Acquisition Performance, Julio Christian Mateo
Browse all Theses and Dissertations
Traditionally, private communication channels with stable characteristics have been used in teleoperation situations. However, recently there have been a few attempts at using public communication channels such as the Internet. In spite of their convenience, very little is known about the effect of the variable delays inherent in this type of channel on motor performance. In this thesis, we provide empirical data on the impact of variable feedback delays on a 3D visual target-acquisition task performed in a virtual environment. Target size, distance between targets, mean feedback delay, and feedback-delay variability were manipulated and the number of errors and movement …
The Relationship Between Burnout And Engagement: A Confirmatory Factor Analysis, Gene Michael Alarcon
The Relationship Between Burnout And Engagement: A Confirmatory Factor Analysis, Gene Michael Alarcon
Browse all Theses and Dissertations
Researchers have purported that burnout and engagement measure the same three latent constructs, energy, identification, and efficacy at work, but few have actually researched the theory (Maslach & Leiter, 1997; Schaufeli & Bakker, 2004). Burnout has been consistently related to workplace demands such as emotional labor (Brotheridge & Grandey, 2002; Brotheridge & Lee, 2002). The current study investigated whether burnout and engagement are comprised of energy, identification, and efficacy in a sample with high demands for emotional labor. A confirmatory factor analysis suggested that burnout and engagement might in fact be separate second order latent constructs comprised of only two …
Cognitive Ability, Job Knowledge, And Stereotype Threat: When Does Adverse Impact Result?, Mark V. Palumbo
Cognitive Ability, Job Knowledge, And Stereotype Threat: When Does Adverse Impact Result?, Mark V. Palumbo

This research compared the efficacy of a cognitive ability test and two types of job knowledge tests for predicting job performance. Further, I examined job knowledge as a mechanism through which cognitive ability affects performance. Finally, I examined both types of tests relative to specific propositions from stereotype threat theory. Specifically, I examined the propositions that perceptions of the tests may cause mean score differences between Blacks and Whites and compared the effects of test perceptions relative to both test types. Results demonstrated that job knowledge accounted for significantly more variance in task performance than cognitive ability. Furthermore, job knowledge …
The Effects Of Representational Format And Discourse Principles On The Comprehension And Production Of Temporal Order, Louise J. Rasmussen
The Effects Of Representational Format And Discourse Principles On The Comprehension And Production Of Temporal Order, Louise J. Rasmussen
Browse all Theses and Dissertations
In the present study I examined the role physical representations play in supporting distributed planning and scheduling. Specifically, I investigated the implications of different representational formats for the production of discourse as well as the later comprehension of text relating to temporal order. In the first part of the study, pairs of participants created schedules for constructing a house with the aid of either a numeric, list format, or a graphical, Gantt chart format. Participants completed the task in a non-collocated fashion, without shared visual access. In the second part of the study, after completing their schedule, the same participants …
