The Relation Between Globalization And Personal Values Across 53 Countries And 28 Years, Irina Florentina Cozma

Doctoral Dissertations

The aim of this research is to examine the relation between the change in globalization and change in personal values (work and general life values). An analysis across 28 years and 53 countries suggests that changes in different personal values have different relations with the change in globalization. Moreover, this relation is influenced by the demographic characteristics of the sample. The present research contributes to the literature in the following ways: 1) linking globalization (an economic concept) and personal values (a psychological concept), 2) providing an analysis of the relation between the change in personal values and the change in …

Power And Identity In Three Gothic Novels: The Mysteries Of Udolpho, Caleb Williams, And Melmoth The Wanderer., Jerry Jennings Alexander

Doctoral Dissertations

Abstract

This study examines the connection between power and identity in three Gothic novels, Ann Radcliffe’s The Mysteries of Udolpho, William Godwin’s Caleb Williams, and Charles Robert Maturin’s Melmoth the Wanderer. Following the identity theories of Erik Erikson, I argue that identity has biological, psychological, and social aspects that are subject to change over time. As individual agency—the ability to function as a person—depends on a relatively certain and stable sense of personal identity, Gothic villains—both individuals and institutions—gain and maintain their power by disempowering their victims. In order to do so, they work to compromise these …

The Relationship Between Secondary School Teachers' Perceptions Of Principal Ethical Leadership And Organizational Health, Jessica H Chambers

Doctoral Dissertations

The purpose of this descriptive, correlational study was to determine if any significant relationships existed between secondary school teachers’ perceptions of principal leader integrity as measured by the Perceived Leadership Integrity Scale ([PLIS], Craig & Gustafson, 1998) and schools’ organizational health as perceived by secondary school teachers and gauged by the Organizational Health Inventory for Secondary Schools ([OHI-S], Hoy & Feldman, 1987). The study also explored the seven OHI-S dimensions: (1) Institutional Integrity, (2) Initiating Structure, (3) Consideration, (4) Principal Influence, (5) Resource Support, (6) Morale, and (7) Academic Emphasis—and their relationships with the demographics of the sample.

Doctoral Dissertations

This dissertation consists of three chapters that explore environmental policy. Chapter 1 empirically investigates the potential for incentives to encourage the adoption of low-emission alternatives to gasoline motorcycles. Hanoi, Vietnam, like many Asian cities, is experiencing rapid growth in the ownership of personal gasoline-powered motorcycles and scooters, and along with this heightened air quality issues. Electric scooters have the potential to reduce air pollution as an alternative to gasoline-powered motorcycles; however, electric scooters have yet to penetrate the Vietnamese and other large Asian markets. This study uses a choice experiment survey to elicit the demand for electric scooters, with focus …

Self-Direction And Technology Use Among New Workforce Entrants, Lila Louise Holt

Doctoral Dissertations

With the knowledge age evolving, colleges and universities should be ever vigilant to assure that the pedagogies practiced are adequately preparing future workers with skills required to keep pace (Scardamalia & Bereiter, 2006). Business managers have identified self-direction and technology use as increasingly important in the 21^st century (Partnership for 21st Century Skills, 2006), yet a gap in research of pedagogies that advance self-directedness and promote technology use has been found. To help identify new pedagogies, the purpose of this study was to identify the relationship between self-directed learning (SDL) and technology use of people …

Temporal Patterns Of Functional And Dysfunctional Employee Turnover, Matthew Scott Fleisher

Doctoral Dissertations

This study examined temporal patterns in collective employee turnover over a 75 month interval. Time series models were fit to subgroups of functional and dysfunctional turnover. Dysfunctional turnover was defined as voluntary separation among high and average performers and functional turnover was defined as voluntary separation of low performers. Results provided support for the hypothesis that temporal patterns of functional and dysfunctional turnover differ. Patterns among high and average performers were similar, such that employee turnover across several global regions increased during or near July. In contrast, employee turnover among low performers tended to spike during or soon after October. …

Teachers’ Perceptions Of Job Satisfaction And School Climate In An Era Of Accountability: A Mixed Methods Study Of Two High Schools On Tennessee’S High Priority List, Jeffrey Anton Knox

Doctoral Dissertations

This mixed methods study examines how teachers and administrators react when the school is under the stress of an accountability system. In this study, teacher job satisfaction and school climate are measured as these often overlooked variables have a great impact on student academic achievement (Goddard, Sweetland, & Hoy, 2000). Accountability systems such as No Child Left Behind need to be explored for negative unintended consequences such as the lowering of teacher job satisfaction and school climate. Questionnaires, interviews, and observations are used to measure teachers’ job satisfaction and school climate of two high schools that have been on Tennessee’s …

Improving Facilitation Through Levelising: Reflecting In And On Practice, Willard Donald Creekmore

Doctoral Dissertations

This study explored the experience of engaging in reflective practice through the framework of Levelising. Reflective practice has been of interest to professionals and educators of professionals for many years. However, Levelising is a recently introduced approach. Levelising categorizes the reflective process into four modes. These modes include an awareness of what is occurring (Level I), considering one’s actions (Level II), considering one’s conceptual frame (Level III), and considering the conceptual frames of others (Level IV). This study focuses on my personal experience of improving my facilitation using Levelising as a framework for reflective practice. The context of the study …

Geographic Disparities Associated With Stroke And Myocardial Infarction In East Tennessee, Ashley Pedigo Golden

Doctoral Dissertations

Stroke and myocardial infarction (MI) are serious conditions whose burdens vary by socio-demographic and geographic factors. Although several studies have investigated and identified disparities in burdens of these conditions at the county and state levels, little is known regarding their geographic epidemiology at the neighborhood level. Both conditions require emergency treatments and therefore timely geographic accessibility to appropriate care is critical. Investigation of disparities in geographic accessibility to stroke and MI care and the role of Emergency Medical Services (EMS) in reducing treatment delays are vital in improving health outcomes. Therefore, the objectives of this work were to: (i) classify …

“This Is Me. I Like Who I Am”: A Qualitative Descriptive Study Using Photo Elicitation To Examine The World Of The School-­Age Child With Cystic Fibrosis, Renee Carol Burk

Doctoral Dissertations

School-age children with Cystic Fibrosis (CF) possess valuable knowledge about themselves. They have experience and ability to offer insight about living with CF. Previous studies, exploring the perceptions of CF children, give little attention to eliciting and listening to their voices. Also, traditional data collection methods limit children from participating in research. The purpose of this study was to explore and describe how school-age children with CF see themselves in the world they live.

The study utilized qualitative description methodology. Symbolic Interactionism served as the researcher’s philosophical lens. It is a perspective that seeks to understand the social world of …

Development Of An Organizational Hardiness Construct: Examining Configurations Of Sensemaking, Organizational Identity, And Enactment., Joshua Lloyd Ray

Doctoral Dissertations

The purpose of this study is to develop the construct of organizational hardiness which is thought to distinguish organizations that thrive under conditions of turbulence and uncertainty from organizations that whither under these same conditions. This new construct is based on individual hardiness which is a constellation of personality dispositions that a large body of empirical work has suggested supports individual performance under conditions of turbulence and uncertainty. Paralleling the individual hardiness dispositions of challenge, commitment, and control, organizational hardiness is posited to consist of the organizational level constructs of sensemaking, organizational identification, and enactment. The development of organizational hardiness …

Development And Application Of Liquid Chromatography-Tandem Mass Spectrometry Methods To The Understanding Of Metabolism And Cell-Cell Signaling In Several Biological Systems, Jessica Renee Gooding

Doctoral Dissertations

Liquid chromatography tandem mass spectrometry has become a powerful tool for investigating biological systems. Herein we describe the development of both isotope dilution mass spectrometry methods and targeted metabolomics methods for the study of metabolic and cell-cell signaling applications.

A putative yeast enzyme was characterized by discovery metabolite profiling, kinetic flux profiling, transcriptomics and structural biology. These experiments demonstrated that the enzyme shb17 was a sedoheptulose bisphosphatase that provides a thermodynamically dedicated step towards riboneogenesis, leading to the redefinition of the canonical pentose phosphate pathway.

An extension of metabolic profiling and kinetic flux profiling methods was developed for a set …

Multiple Responses By Cerulean Warblers To Experimental Forest Disturbance In The Appalachian Mountains, Than James Boves

Doctoral Dissertations

The Cerulean Warbler (Setophaga cerulea) is a mature forest obligate and one of the fastest declining songbird species in the United States. This decline may be related to a lack of disturbance within contemporary forests; however, the consequences of disturbance on the species have not been rigorously evaluated. Thus, we assessed multiple responses by Cerulean Warblers to a range of experimental forest disturbances across the core of their breeding range in the Appalachian Mountains. We quantified individual and population responses to these manipulations, and assessed the potential consequences of disturbance on the sexual signaling system. Male ceruleans were …

Avoidance And Depression: Evidence For Reinforcement As A Mediating Factor, John Paul Carvalho

Doctoral Dissertations

Behavioral Activation theory (Martell, Addis, & Jacobson, 2001) posits that a pattern of excessive use of avoidant coping strategies removes an individual from environmental sources of reward and reinforcement and subsequently leads to the development (or maintenance) of depressive symptoms. This investigation examined this theory by establishing measures of environmental reward as mediators between avoidance and depression, while further demonstrating that there is a strong connection between avoidance and depression independent of anxiety. Reward was measured by both self-report questionnaire (Reward Probability Inventory; Carvalho et al., under review) and daily activity diary ratings (Hopko, Bell, Armento, Hunt, & Lejuez, 2003), …

Risk Factors For Intimate Partner Violence During Pregnancy, Julianne Christina Hellmuth

Doctoral Dissertations

Intimate partner violence (IPV) has been shown to be highly prevalent during pregnancy, particularly for couples of low socioeconomic status. IPV poses an especially serious problem for pregnant women as it puts both mother and unborn child at risk for severe physical harm, including death. This investigation of potential risk factors for IPV during pregnancy examines alcohol use, stress, suspicion of infidelity, jealousy, and relationship discord from both a cross-sectional and longitudinal perspective. The overarching theoretical frameork for this study is based on Leonard's conceptual model of substance use and intimate partner violence in combination with evolutionary theory as discussed …

Racial Prejudice, Homophobia, And Sexism As A Function Of Right-Wing Authoritarianism, Religious Values, Religious Pressures, And Religious Orientation, Dixie Turner

Doctoral Dissertations

Past literature is ambiguous regarding relationships among different religious variables and prejudice. The purpose of this study was to clarify complicated relationships among religious pressures, religious fundamentalism, Christian orthodoxy, intrinsic and extrinsic religious orientation, quest orientation, right-wing authoritarianism, and the outcome variables of racial prejudice, homophobia, and sexism. Two models, a developmental model and social learning model, were proposed in this study and were tested using structural-equation modeling. Participants were 310 self-identified Christian students. Several predicted paths were deleted in both models because they did not contribute to good fit. Three predictor variables: Christian orthodoxy, extrinsic religious orientation, and religious …

The Effectiveness Of A Substance Abuse Treatment Group For At Risk College Students, Melissa D. Simundson

Doctoral Dissertations

There has been limited research in the area of treatment effectiveness for college students who abuse substances (e.g., alcohol, marijuana). There is no published research to date that addresses the effectiveness of college students' substance abuse counseling groups utilizing therapeutic reactance as a covariate. The purpose of this study was to examine the effectiveness of motivational interviewing and cognitive therapy techniques with a university counseling center substance abuse group and the extent to which group members' levels of reactance influence the treatment outcome. There were 35 college students approximately 18-25 years of age in six groups with an average of …

Balancing Student Participation In Large College Courses Via Randomized Credit For Participation, Daniel Fox Mccleary

Doctoral Dissertations

The current study was an extension of research reported by Krohn (2010), which showed that daily credit for self-reported participation in designated credit units tended to balance participation across students (i.e., fewer non-participants, more credit-level participants, and fewer dominant participants). The purpose of the current study was to determine if similar results would be achieved by randomly selecting half of the discussion days in designated credit units for participation credit.

The study was done in 3 large sections of an undergraduate class (approximately 54 students per class). Students self-recorded their in-class comments each day on specially designed record cards. At …

Inter-Rater Reliability And Related Variables Of A Newly Developed Measure Of Quality Of Student Participation, Lisa Nicole Edge

Doctoral Dissertations

Some researchers suggest that quality is preserved when students are rewarded for quantity of class participation (Boniecki & Moore, 2003; Bruss, 2009; Mainkar, 2007; Zaremba & Dunn, 2004); however, few studies have targeted the systematic assessment of participation quality. The primary purpose of the study was to develop a reliable system for rating quality of student participation, investigate whether quality of participation is preserved when students are given credit for the amount of class participation, and examine the relationship between participation quality and important course variables.

The researcher in the current study developed a rating system to evaluate the quality …

Sexual Objectification And Substance Abuse In Young Adult Women, Erika Ann Carr

Doctoral Dissertations

Objectification Theory (Frederickson & Roberts, 1997) provides a framework for understanding the experiences of women living in a culture that sexualizes the female body. The purpose of this study was to extend the tenets of Objectification Theory by postulating that external and internalized experiences of sexual objectification may be related to women’s substance abuse in a sample of 289 young adult females. Findings indicated that sexual objectification experiences and self-objectification were both positively correlated with alcohol abuse. Sexual objectification was also positively correlated with nicotine abuse and other drug abuse. Furthermore, the findings provided support for a theorized mediated model …

The Effect Of Reflective Writing Interventions On Critical Thinking Skills, Jessica L Naber

Doctoral Dissertations

The importance of critical thinking as an outcome for students graduating from undergraduate nursing programs is well-documented by both the American Association of Colleges of Nursing (AACN) and the National League for Nursing (NLN). Graduating nurses are expected to apply critical thinking in all practice situations to improve patient health outcomes. Reflective writing is one strategy used to increase understanding and ability to reason and analyze. The lack of empirical evidence regarding the effectiveness of reflective writing interventions on increasing critical thinking skills supports the need for examining reflective writing as a critical thinking strategy. The purpose of this study …

Emotion Regulation As A Mediator Of Adolescent Developmental Processes And Problem Outcomes, Katherine Little Kivisto

Doctoral Dissertations

Recent models of adolescent development and psychopathology emphasize the importance of the social regulation of emotion during adolescence (Allen & Manning, 2007; Allen & Miga, 2010), and emotion regulation as a mediating factor between multiple aspects of adolescent development and adolescent adjustment (Morris, Silk, Steinberg, Myers, & Robinson, 2007). The present dissertation investigated these two phenomena in two separate studies of adolescent development, emotion regulation, and psychological adjustment.

In study one, a new measure of adolescent social regulation of emotion – the Managing Distress Interpersonally Scale, or MANDI – showed good internal consistency, test-retest reliability and factor structure across two …

Dynamics, Electromyography And Vibroarthrography As Non-Invasive Diagnostic Tools: Investigation Of The Patellofemoral Joint, Filip Leszko

Doctoral Dissertations

The knee joint plays an essential role in the human musculoskeletal system. It has evolved to withstand extreme loading conditions, while providing almost frictionless joint movement. However, its performance may be disrupted by disease, anatomical deformities, soft tissue imbalance or injury. Knee disorders are often puzzling, and accurate diagnosis may be challenging. Current evaluation approach is usually limited to a detailed interview with the patient, careful physical examination and radiographic imaging. The X-ray screening may reveal bone degeneration, but does not carry sufficient information of the soft tissue conditions. More advanced imaging tools such as MRI or CT are available, …

Immunologic Risk Prediction Model For Kidney Graft Function, Christina Diane Bishop

Doctoral Dissertations

Clinicians lack appropriate non-invasive methods to be able to predict, diagnose, and reduce the risk of rejection in the years following kidney transplantation. Protocol biopsies and monitoring of serum creatinine levels are the most common methods of monitoring graft function after transplant; however, they have several negative aspects. Use of traditional factors regarding donors and recipients such as Human Leukocyte Antigen (HLA) DNA typing, pre-transplant anti-HLA antibody levels, and basic demographics (age, ethnicity/race, gender), has proved inadequate for post-transplant graft monitoring past the first few years. We propose that by utilizing immunologic factors available to clinicians across the United States, …
