The "Christian Faith Factor" And The African American Child During The Early Childhood Years, Julia Williams

Electronic Theses and Dissertations

The purpose of this research was to determine if African American children progressed through developmental faith stages in the same manner as the subjects described by Fowler in his seminal work on faith development (1981). In Developmental Psychology, many theories with stages have been developed and many studies conducted in the areas of cognitive, psychosocial, creative, and moral development. These studies have explored Erickson's stages of psychosocial development, (1963); Kohlberg's stages of moral development, (1969); and Piaget's stages of cognitive development (1967). There remains, however, limited research examining faith development and faith experiences with African American children during the early …

On The Day You Were Born: A Phenomenological Study Of Fathers' Experience Of Being Present At Their Children's Birth, Nick Williams

Electronic Theses and Dissertations

This dissertation is a qualitative investigation into the lived experience of becoming a father through witnessing the event of childbirth. I analyze transcripts of conversations between five fathers and myself using a phenomenological method to distinguish meaningful and psychologically significant statements. I then weave these statements into a series of thematically and structurally consistent narratives that reflect the fathers' attitudes and experiences concerning becoming and being a father. From these narratives, I draw together themes that appeared across multiple fathers' stories. These themes consist of the father's relationship with the social world, including fathers in relation to other fathers and …

The Role Of Expectancies In Binge Eating Behavior, Jessica Larose

Electronic Theses and Dissertations

The central aim of the present study was to examine the role of expectancies in binge eating behavior. Two distinct statistical techniques were used to accomplish this goal. First, regression analyses were conducted using variables previously identified in the literature, as well as eating expectancies as measured by the Eating Expectancy Inventory (EEI). For both females and males, regression equations including expectancies accounted for a substantial portion of the variance in binge eating behavior. Second, memory modeling techniques were used to model the probable organization of eating expectancies. Memory modeling of hypothetical expectancy networks has lead to successful interventions in …

Event Planners' Ratings Of Destination Selection Variables: A Comparison Between Members Of Three Professional Association Groups, Marta Godlewska

Electronic Theses and Dissertations

Several researchers have attempted to understand the destination selection criteria that are important to event planners (Crouch & Ritchie, 1998; Getz, 2003; Oppermann, 1996). However, an examination of the previous studies indicated that only limited understanding of the destination selection criteria has been provided. There is little research that compares event planners belonging to different professional associations and their rating of destination selection criteria. This study examined the differences that exist between three groups of event planners in rating thirteen destination selection variables. The study provides more understanding in the search of an optimal combination of destination selection mix based …

A second purpose of this study was to compare college students (n = 158) with their parents on their attitudes toward mental illness and toward seeking counseling. Among predictor variables, social stigma and the belief that mental illnesses are untreatable were the primary variables predicting attitudes toward seeking counseling. The more college students and their parents perceived there to be social stigma attached to those seeking therapy, and …

Identification Of System Design Features That Affect Sickness In Virtual Environments, Julie Drexler

Electronic Theses and Dissertations

The terms "simulator" and "VR" are typically used to refer to specific types of virtual environments (VEs) which differ in the technology used to display the simulated environment. While simulators and VR devices may offer advantages such as low cost training, numerous studies on the effects to humans of exposure to different VEs indicate that motion sickness-like symptoms are often produced during or after exposure to the simulated environment. These deleterious side effects have the potential to limit the utilization of VE systems if they jeopardize the health and/or safety of the user and create liability issues for the manufacturer. …

Analysis Of Aircraft Arrival Delay And Airport On-Time Performance, Yuqiong Bai

Electronic Theses and Dissertations

While existing grid environments cater to specific needs of a particular user community, we need to go beyond them and consider general-purpose large-scale distributed systems consisting of large collections of heterogeneous computers and communication systems shared by a large user population with very diverse requirements. Coordination, matchmaking, and resource allocation are among the essential functions of large-scale distributed systems. Although deterministic approaches for coordination, matchmaking, and resource allocation have been well studied, they are not suitable for large-scale distributed systems due to the large-scale, the autonomy, and the dynamics of the systems. We have to seek for nondeterministic solutions for …

Variation Of Geotechnical Strength Properties With Age Of Landfills Accepting Biosolids, Kishore Pinapati

Electronic Theses and Dissertations

The solid portion of waste disposal, known as Municipal Solid Waste (MSW) can be landfilled. Landfilling has proved to be a safe, sanitary and economical method of disposal. A by-product from wastewater treatment plants called biosolids is sometimes co-disposed along with MSW in landfills. Recent work at the University of Central Florida has focused on the behavior of the mixture of MSW and biosolids. As an increased amount of waste accumulates in these landfills, it creates a new problem – the geotechnical stability of landfills. In current literature, classical geotechnical testing methods have been followed to find the strength properties …

Caregiver Burden And Coping Responses For Females Who Are The Primary Caregiver For A Family Member Living With Hiv/Aids In Kenya, Veronica Kimemia

Electronic Theses and Dissertations

Caring for a family member who is ill can be a draining experience (Cooper et al., 2006; Daire, 2002; Zarit et al, 1980). Providing care for a family member that is living with HIV/AIDS is potentially even more stressful because of social meanings associated with HIV/AIDS infection (Stajduhar, 1998) and the contagious nature of the HIV virus (Powell-Cope & Brown, 1992). Research indicates that most caregivers are female (Bunting, 2001; Songwathana, 2000). In Africa women bear the brunt of the burden of providing care for family members who are living with HIV/AIDS (Mushonga, 2001; Olenja, 1999). This study examined coping …

Mathematical Modeling Of Smallpox Withoptimal Intervention Policy, Niwas Lawot

Electronic Theses and Dissertations

In this work, two differential equation models for smallpox are numerically solved to find the optimal intervention policy. In each model we look for the range of values of the parameters that give rise to the worst case scenarios. Since the scale of an epidemic is determined by the number of people infected, and eventually dead, as a result of infection, we attempt to quantify the scale of the epidemic and recommend the optimum intervention policy. In the first case study, we mimic a densely populated city with comparatively big tourist population, and heavily used mass transportation system. A mathematical …

The Relation Between Optimism And Job Performance: An Applied Setting, Mary Davis

Electronic Theses and Dissertations

Research on cognitive ability measures consistently concludes that they are predictive of employee performance. While accounting for only about 9% of the variance in performance, however, cognitive ability measures are not sufficient. Alternative measures, such as measures of personality constructs, must be included to fully predict employee performance. The research on personality measures suggests that they are marginally predictive of employee performance. Research also suggests that predicative accuracy of personality measures can be enhanced when the measure is specific to the situation (i.e., stress measure are more predictive of performance in high stress situations compared to moderate or low stress …

Holy Books Or Pocket Books? Class And Values In American Politics, Matthew Keaton

Electronic Theses and Dissertations

There has been much speculation recently as to the political effect that "moral values" have on Americans and much research has shown inconclusive results as far as the effect of class. This paper aims to study how class and values, including moral values and postmaterialist values, interact with politics in the United States. The analyses performed to determine these effects include crosstabulation and logistical regressions and will include data from the National Election Studies (NES). It is found that postmaterialist values have little effect on political behavior but in separate analyses, class and moral values have increasing influences on vote …
