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 …

Theoretical And Empirical Essays On The Effects Of Proposed And Existing Environmental Policies, Luke Robert Jones

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 …

Biofuel And Water Resources, Xia Zhou

Doctoral Dissertations

This dissertation focuses on the economic and environmental benefits of planting switchgrass as a bioenergy feedstock. The first chapter presents a dynamic optimization model of fertilizer and land allocation between switchgrass and corn to estimate economic benefits. Subsequent chapters utilize Geographic Information System (GIS)-based Soil and Water Assessment Tool (SWAT) to be calibrated to evaluate the environmental (nutrient and sediment loading) effects of land use conversion to switchgrass production on water quality and analyze the Water Quality Trading (WQT) program with cost-effectiveness ratios ordered for abatements of nutrient loadings in an East Tennessee watershed.

Relationships Between Externalization Behaviors And Team Cognition Variables In Distributed Teams, Lisa Ann Delise

Doctoral Dissertations

Members of distributed teams often have difficulty sharing unique information with their teammates during decision making tasks. These communication problems may hinder the development of cognitions that allow team members to reach a similar understanding of the content and structure of task information. The C-MAP intervention (Rentsch, Delise, & Hutchison, 2008) was designed to assist team members in sharing their information through behaviors that convey the content and structure of information by using specific communication behaviors and developing a knowledge object. In the present study, the knowledge object took the form of a white board where information was posted and …

Optimal Draw Area And Feedstock Delivery Schedule Of Biorefineries In The Southeast U.S. Based On Least Cost And Producers’ Willingness To Plant A Dedicated Energy Crop, Wen Tu

Doctoral Dissertations

To overcome the limitations of starch-based and sugar-based ethanol, scientists propose to expand the use of cellulosic ethanol. Cellulosic ethanol is a biofuel produced from wood, grasses, or the non-edible parts of plants. As the U.S. has a large cellulosic biomass production base (Perlack et al., 2006), production of ethanol from cellulosic feedstock and use of ethanol as a substitute for gasoline could help promote rural development, reduce green house gases emissions, and increase energy independence. This study focuses on the cost of producing cellulosic ethanol along with the amount of carbon sequestered and emitted using switchgrass as a feedstock. …

Essays On State Lottery Demand And Revenue Earmarks, Kara Diane Smith Mitchell

Doctoral Dissertations

Since the first modern state-sponsored lottery was instituted in New Hampshire in 1964, lotteries have proliferated to 42 states and the District of Colombia. With little exception, research has shown that these lotteries are a highly regressive form of taxation. However, this body of research does not take into account a theoretical finding that the manner in which collected funds are earmarked impacts participation patterns. The goal of this dissertation is to test this finding empirically.

In the first analysis, I use sales data from the Tennessee Education Lottery and scholarship data from the TEL Scholarship program to test this …

A Comparative Analysis Of School Counselors' And School Principals' Perceptions Of School Counselors' Activities, Deborah K Buchanan

Doctoral Dissertations

The purpose of this quantitative, cross-sectional survey study was to compare school counselors’ and principals’ perceptions of the frequency with which school counselors perform activities that align with the ASCA National Model (ASCA, 2005) and those activities that do not, as measured by the School Counselor Activity Rating Scale (SCARS) (Scarborough, 2005). Results indicate that the school counselors and principals that participated in the study agreed that school counselors are spending most of their time engaged in activities that align with the ASCA National Model (ASCA, 2005). Significant differences (p < .05) appeared on 10 items in which five were related to counseling activities, primarily as they relate to small group counseling. Principals indicated their school counselors were conducting small group activities related to academic and substance abuse issues more frequently than the school counselors indicated. Other areas that showed significant differences (p < .05) between school counselors’ and principals’ responses included …

Positive Functioning Among Chinese Adolescents: Conceptualizing A Framework And Testing Effects Of Parenting, Mingzhu Xia

Doctoral Dissertations

Chinese adolescents’ development has received increasing attention over recent decades. However, following a traditional deficit model, most of the attention has been on problematic functioning of adolescents (e.g. depression). This emphasis is not consistent with evidence that the large majority of Chinese adolescents do not manifest such problem behaviors. Little is known about positive functioning among Chinese adolescents and how it is related to key socialization practices such as parenting. The purpose of the present study was to begin to fill these gaps.

Using theory, past empirical practice, and characteristics of Chinese culture, the study posited a second-order structure for …

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. …

If And How Many 'Races'? The Application Of Mixture Modeling To World-Wide Human Craniometric Variation, Bridget Frances Beatrice Algee-Hewitt

Doctoral Dissertations

Studies in human cranial variation are extensive and widely discussed. While skeletal biologists continue to focus on questions of biological distance and population history, group-specific knowledge is being increasingly used for human identification in medico-legal contexts. The importance of this research has been often overshadowed by both philosophic and methodological concerns. Many analyses have been constrained in their scope by the limited availability of representative samples and readily criticized for adopting statistical techniques that require user-guidance and a priori information. A multi-part project is presented here that implements model-based clustering as an alternative approach for population studies using craniometric traits. …

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 …

After The Final Bell: The Self-Directed Learning Practices Of Elementary Teachers, Susan Renee Wagner

Doctoral Dissertations

Are elementary teachers self-directed learners? If so, do their learning activities outside their classrooms translate into their classrooms? The purpose of this study was to examine the relationship, if any, between elementary teachers’ self-directed learning and activities in their classrooms. A two phase, mixed methods design first utilized a quantitative study from which the results were used to denote the type of data collected in the second, qualitative phase. The quantitative Phase I of this study involved using a survey instrument in order to identify self-directed learners and identify categories of teacher learners. These quantitative data were gathered through the …

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 …

Juvenile Competence To Stand Trial: An Examination Of The Effects Of Cognitive Ability, Psychiatric Symptomatology, And Psychosocial Maturity, Aaron John Kivisto

Doctoral Dissertations

As the courts have evolved over the past 30 years towards increasingly punitive sanctions for youthful offenders, the fundamental protections afforded to adult defendants have become increasingly relevant for youthful offenders. Among these protections, the right of juveniles to be competent to stand trial has gained nearly universal recognition throughout this country’s courts. Congruent with theory and previous research, we hypothesized that age, intellectual ability, psychiatric symptomatology, and maturity would all be directly related to adolescents’ competence. It was also anticipated that adolescents in the detention sample would evidence lower maturity and competency-related abilities compared to the community sample. Expanding …

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 …

The Impact Of Repeated Sensory-Motor Experience With Multimodal Objects Upon The Emergence Of Infant Reaching, Joshua L Williams

Doctoral Dissertations

Previous studies found that providing infants with repeated opportunities for reaching improved the emergence and quality of the behavior, presumably via exploratory and selective processes (Bojczyk & Corbetta, 2004; Lobo et al., 2008). Here we further examined the effects of opportunities for reaching by exposing infants to multimodal objects that were activated either continuously by a hidden motor or contingently by hand-toy contact. We asked if such objects would motivate infants to try to reach for them even more than still and silent objects.

Forty-four pre-reaching infants were recruited within the week prior to turning three months of age and …

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 …

The Pleasure And Participation Sports Model As Reflected Through An Advanced Physical Education Course, Rebecca R Buchanan

Doctoral Dissertations

The purpose of this study was to explore how the pleasure and participation sports model as described by Coakley (2009) was reflected through an Advanced Physical Education course. This included an analysis examining whether the model was supported, expanded, or refuted based on characteristics of the model emphasizing (a) democratic leadership, (b) inclusive participation, and (c) the use of cooperation and competition with others to develop and test skills in a healthy and enjoyable context.

A single-site, exploratory, qualitative case study design provided the opportunity to investigate the phenomenon under exploration. A particular Advanced Physical Education course was purposefully selected …

Behavioral Activation Of Religious Behaviors: Treating Depressed College Students With A Randomized Controlled Trial, Maria Elizabeth Anne Armento

Doctoral Dissertations

Abstract

Although spiritual or religious behaviors are sometimes targeted within behavioral activation protocols (Hopko & Lejuez, 2007; Hopko, Lejuez, Ruggiero, & Eifert, 2003), the efficacy of a protocol that exclusively develops a religiously-based behavioral repertoire has not been investigated. This randomized controlled study investigated the efficacy of a brief protocol for religious action in behavioral activation (PRA-BA) relative to a no-treatment “support” condition among mild to moderately depressed undergraduate students (n = 50). PRA-BA consisted of an individualized one-session intervention and 2-week activation interval. Clinical outcomes assessed depression, environmental reward, anxiety, and quality of life. Repeated measures ANOVAs indicated …

The Double-Edged Sword Of Self-Enhancement: A Longitudinal Examination Of The Effects Of Self-Enhancement On Psychological And Physical Well-Being Among Individuals With Multiple Sclerosis, Erin Marie O'Mara

Doctoral Dissertations

The present study prospectively examines factors that affect whether self-enhancement exerts favorable or unfavorable effects on both psychological and physical well-being in a context that is less controllable than other contexts in which self-enhancement has been examined (e.g., academic performance), an at risk population of Multiple Sclerosis (MS) patients. In particular, the present study (a) examines whether self-enhancement differentially predicts psychological and physical well-being when self-enhancement is related or unrelated to the well-being outcomes, and (b) whether self-enhancement interacts with severity of circumstances (i.e., course of MS) to predict psychological and physical well-being, as suggested by O’Mara, McNulty, & Karney …

Complex Adaptive Systems Theory Applied To Virtual Scientific Collaborations: The Case Of Dataone, Arsev Umur Aydinoglu

Data is generated through conducting 15 semi-structured interviews, observing three 3-day meetings, and 51 online surveys. The main contribution of this study is the development of a complexity framework and its application to a project such as DataONE. The findings reveal that DataONE behaves like a complex adaptive system: various individuals and institutions interacting, adapting, and coevolving to achieve their own and common goals; during the process new …

Essays On Timing Of Firm Actions In Industrial Economics, Youping Li

Doctoral Dissertations

The timing of actions by firms plays an important role in industrial economics. It is key to strategic advantage in oligopoly models whether firms compete on quantity or on price. In a vertical relationship between input suppliers and final-good manufacturers, a firm which chooses a strategy first will take into account the response by those firms moving second and different sequence of play leads to different market outcomes. In my dissertation, I study the determinants and implications of the timing of firm actions in a variety of scenarios. In my first two essays, I examine how market leadership may arise …

Decolonial Multiculturalism And Local-Global Contexts: A Postcritical Feminist Bricolage For Developing New Praxes In Education, Katharine Matthaei Sprecher

Doctoral Dissertations

This dissertation presents a conceptual bricolage that explores complex, reflexive, and interrelated dimensions of educational praxes. My work is grounded in the assertion that the ever-changing, local-global nature of contemporary societies requires new approaches to curricula, pedagogies, policies, and practices in U.S. schools to meet the challenges and opportunities of a global era. Presenting my research and findings as four articles, I begin with a dialectical analysis of theoretical and pedagogical literatures to develop an adaptable framework for decolonial multicultural education. In Article 1, I demonstrate how this framework synergizes aspects of social reconstructionist and critical multicultural, global, and …
