Post-Concussion Experiences Of Collegiate Student-Athletes, Kaitlin Iris Singer

Doctoral Dissertations

Sports-related concussions are a major public health concern affecting a significant number of collegiate student-athletes. Medical and public health research has addressed every aspect of concussion management processes including concussion education, medical diagnosis, recovery, and returning to sport and classroom. This research has led to several best-practices for concussion management. Since 2010, the NCAA has mandated that its member institutions maintain concussion management policies and procedures. However, the current recommendations, based primarily on medical research, have been found in quantitative studies of the behaviors and practices of athletic trainers, coaches, and student-athletes to be ineffective. To date, no studies have …

Factors Influencing Greenhouse Gas Emissions From Land Use, Land-Use Change, And Forest Activities, Pattarawan Watcharaanantapong

Doctoral Dissertations

Greenhouse gas (GHG) emissions are a major global issue because of their effects on climate and the resulting environmental and human impacts. The primary greenhouse gases (GHGs), carbon dioxide (CO₂), methane (CH₄), and nitrous oxide (N₂O), are emitted into the atmosphere from a myriad of human activities such as energy supply, manufacturing, transportation, commercial and residential buildings, and waste. Additionally, management activities on agricultural and forest lands can influence GHG emissions substantially. Even though GHGs can be released into the air via the sectors mentioned, GHGs, especially CO₂, can be removed from …

Exploring The Professional Identity Development Of Counselors-In-Training Through Experiential Small Groups, Amanda Christine Dediego

Doctoral Dissertations

The concept of professional identity of counselors is a recent area of focus within the counseling profession. The Council for Accreditation of Counseling and Related Educational Programs standards for counselor education programs of all specialties reflect the trend towards establishing a strong professional identity for counselors. One factor shown to be influential in professional identity development has been experiential learning opportunities, which allow counselors-in-training to develop an individual professional identity through application of educational content in real-world scenarios. The literature suggests experiential learning is a pivotal opportunity for professional identity development for entry-level counseling students. One opportunity for experiential learning, …

Treatment Preferences And Outcome In A Randomized Controlled Trial For Depression Comparing Supportive-Expressive Therapy To Medication And Pill Placebo, Sophia Elsie Winter

Doctoral Dissertations

Previous research regarding the relationship between patient treatment preferences on outcome has been equivocal, with some studies finding a significant relationship between preference match and outcome, and others finding no such evidence. This study examines the effect of patient treatment preference match on outcome using data from a previously published randomized controlled trial comparing supportive-expressive therapy (SET), to antidepressant medication plus clinical management, and to pill-placebo plus clinical management. The original study included 156 participants receiving treatment at the Center for Psychotherapy research at the University of Pennsylvania in Philadelphia, PA. This study is the first to examine the relationship …

Neuropsychological Effects Of Placebo Stimulants In College Students, Samantha Jayne Lookatch

Doctoral Dissertations

The past 15 years has seen increases in the nonmedical use of prescription stimulants (NMUPS; e.g., Adderall, Ritalin, Focalin) across college students with rates reported between 6 and 34 percent. Many underestimate or ignore the serious side effects associated with stimulant medication. Furthermore, stimulant medications used to treat ADHD are classified as Schedule II drugs by the Drug Enforcement Agency as they provide beneficial outcomes when used as a prescription medication, but have a high potential risk for abuse, rendering the diversion and unprescribed use illegal. There is also the ethical dilemma that arises when students have access to prescription …

How Do People In Animal Welfare Fields Respond To Family Violence Situations?, Bethanie Allison Poe

Doctoral Dissertations

Cross-reporting refers to the idea that people working in human welfare and people in animal welfare fields who observe or have suspicions of abuse or neglect of children, domestic violence, elderly or disabled people, or animals, respectively, are obligated to report their observations to the appropriate agencies. This exploratory study investigates the types of maltreatment witnessed or observed while at work by people in animal related fields; what responses these workers are making to what they are seeing; and the factors influencing their responses. Using an open online survey, this study found that 21% to 29% of the participants indicated …

Academic Work Ethic In Middle School Students: Extending Scale Research And Investigating Construct Validity, Emily Pendergrast Taylor

Doctoral Dissertations

This three-study dissertation was designed to: 1) extend the research on Parkhurst’s (2013) Academic Work Ethic-Student (AWE-S) scale, 2) develop and analyze reliability of the Academic Work Ethic-Teacher (AWE-T) scale, and 3) expound on the construct validity of academic work ethic by comparing AWE-S and AWE-T scores to external factors (i.e., grades, perceived support, and parental work ethic) and Grit (Duckworth, 2007), a similar construct. Research was conducted in both rural and urban middle schools in Tennessee and included student, teacher, and parent participants.

Both scales were found to have high reliability coefficients and stable factor structures. Student scale (AWE-S) …

Development And Validation Of The Statistics Assessment Of Graduate Students, Dammika Lakmal Walpitage

Doctoral Dissertations

This study developed the Statistics Assessment of Graduate Students (SAGS) instrument, and established its preliminary item characteristics, reliability, and validity evidence. Even though there are limited number of assessments available for measuring different aspects of statistical cognition, these previously available assessments have numerous limitations. The SAGS instrument was developed using Rasch modeling approach to create a new measure of statistical research methodology knowledge of graduate students in education and other behavioral and social sciences. Thirty-five multiple-choice questions were written with stems representing applied research situations and response options distinguishing between appropriate use of various statistical tests or procedures. A focus …

The Decline Of Agriculture And The Rise Of Republican Party Strength In The South, John Marshall Dickey

Doctoral Dissertations

In recent decades, there has been an extensive examination of the resurgence of the Republican Party in the American South in the period after World War II. There were many events that occurred during this time period that might have helped the Republican Party achieve increased success at getting Republican candidates elected in the South. One of the relationships that should be explored is the relationship between the decline of agriculture as the primary provider of jobs and economic prosperity, and the increased ability of the Republican Party to win election to public office. The purpose of this project is …

Remediating A Toxic Town: Power, Place, And Justice In Anniston, Alabama, Melanie Ann Barron

Doctoral Dissertations

This dissertation examines a struggle for Environmental Justice over the long term to understand the impacts of current state-led strategies for achieving Environmental Justice. Recent geographic scholarship in Environmental Justice literatures suggests that state-centric strategies come with problems scholars have yet to fully comprehend. This dissertation, based on fieldwork and archival research in Anniston, Alabama, supports this claim with three main findings: 1) Corporations produce scaled identities to advantageously empower themselves and weather shifts in their profitability, while ordinary people are limited in their capacity to respond in kind to such unequal power arrangements. 2) Current legal solutions for Environmental …

A Characterization Of Human Burial Signatures Using Spectroscopy And Lidar, Katie Ann Corcoran

Doctoral Dissertations

This study is an analysis of terrestrial remote sensing data sets collected at the University of Tennessee’s Anthropology Research Facility (ARF). The objective is to characterize human burial signatures using spectroscopy and laser scanning technologies. The development of remote human burial detection methodologies depends on basic research to establish signatures that inform forensic investigations. This dissertation provides recommendations for future research on remote sensing of human burials, and for investigators who wish to apply these technologies to case work.

Data used in this study include terrestrial spectra, aerial hyperspectral imagery, satellite multispectral imagery, terrestrial light detection and ranging (LIDAR), and …

Reconstructing Late Holocene Fire, Agriculture, And Climate From Sediment Records In Costa Rica And The Dominican Republic, Erik Nicholas Johanson

Doctoral Dissertations

We use multiple proxies from sediment cores to identify periods of climate stress during the late Holocene across the circum-Caribbean region and to determine how fire activity and signals of Pre-Columbian agriculture coincide with these arid periods. We examine evidence of aridity from stable carbon isotope ratios and shifts in elemental composition, along with pollen and microscopic charcoal, at Bao Bog in the highlands of Hispaniola. We infer two major periods of aridity (3600–2300 and 1040–850 cal yr BP), with the later period associated with the late phase of the Terminal Classic Drought. A third, less marked interval of aridity …

Understanding Population-Specific Age Estimation Using Multivariate Cumulative Probit Regression For Asian Skeletal Samples, Ji Eun Kim

Doctoral Dissertations

For many years, the field of anthropology has encouraged anthropologists to assume that population variation exists in skeletal aging although interpretations of population specificity in skeletal aging have been inconsistent. This project investigates age progressive changes in modern East and Southeast Asian populations, and attempts to quantify the magnitude of differences or similarities in skeletal aging between different Asian groups as a first step to develop a more inclusive age estimation method for Asian populations. Specifically, this study explores the utility of currently available age estimation methods for Asian populations, asks whether a population-specific aging method should be region-specific (Thai …

Shades Of Green: A Comparative Analysis Of U.S. Green Economies, Jenna Ann Lamphere

Doctoral Dissertations

Recent attention from scholars, policymakers, and practitioners has focused on the importance of green economy development in achieving sustainability. Efforts, however, have been complicated by the lack of agreement on what a green economy is or how to transition to one. Drawing insights from environmental sociology, new state theory, and science and technology studies, I conduct a comparative analysis of select U.S. cities with recognized green economies. Findings indicate that in each economy, the strength and role of institutions and actors is unique, forming distinct networks that vary in their pursuit of socio-environmental goals.

Three Essays On Sustainable Development In China: Social, Economic And Environmental Aspects, Ying Chen

Doctoral Dissertations

The first essay focuses on the role of the hukou (i.e. Household Registration System) with full awareness of the economic system it operates under, and the development model it assists. I find that hukou’s main role in the planned economy was to assist socialist industrialization while averting the Lewis development model, a development strategy based on unlimited supply of labors from the rural sector, largely adopted in developing countries. In the market reform period, hukou performed exactly the opposite function, which is to assist the Lewis model based on the unlimited supply of rural surplus labor “released” from the …

When Mom Goes To School: Maternal Education And Intergenerational Mobility, Maura E. Devlin

Doctoral Dissertations

This study examined the relationship between the timing of maternal education and children’s educational attainment and the extent to which this relationship differs by gender. I used data from the National Longitudinal Survey of Youth 1979 and the Child and Youth Survey to determine the timing of mothers’ education relative to the birth of their children, with additional predictors associated with children’s educational attainment included in quantitative analyses. ANOVA analyses identified statistically significant differences in educational attainment among the children grouped by mother-category, based on the timing of their mothers’ education, and between genders. Regression analyses found no statistical difference …

Distributing Condoms And "Hope": Race, Sex, And Science In Youth Sexual Health Promotion, Chris A. Barcelos

Doctoral Dissertations

This project uses discursive, visual, and ethnographic approaches situated in a critical feminist methodology to understand how ways of knowing about youth sexuality and reproduction influence community health work. I understand the “problem” in this inquiry as the discursive contexts that limit critical ways of knowing about young people’s sexual subjectivities and practices and about the design of policies and programs. Although race, class, gender, and sexuality are understood in the public health literature as important social determinants of health, there is a lack of research that applies a critical, feminist lens to these constructs. I draw on three years …

The Effect Of Unique Labels On Face Perception In Infancy, Hillary R. Hadley

Doctoral Dissertations

Faces are universally important for a variety of reasons, ranging from identifying individuals to conveying social information. During the first year of life, infants’ experience with commonly encountered face groups shapes how infants perceive familiar and unfamiliar faces. Between 6 and 9 months of age, infants become worse at differentiating among individual faces from unfamiliar face groups (e.g., other-species faces), a process known as “perceptual narrowing”. Labeling faces from a previously unfamiliar face group has been found to promote individual-level differentiation, as well as expert neural processing for the face group. However, it is currently unclear what influences individual-level labels …

The Neural Correlates Of Emotion Reactivity And Regulation In Young Children With Adhd, Claudia I. Lugo-Candelas

Doctoral Dissertations

Attention-deficit hyperactivity disorder (ADHD) is the most frequently occurring pediatric neurobehavioral disorder. Although emotion reactivity and regulation are frequently impaired in ADHD, few studies have examined these factors in preschool aged children with ADHD, and none have explored the neural correlates of emotion reactivity and regulation in this group though event-related potentials (ERPs). Children aged 4 to 7 with (n = 24) and without (n = 30) ADHD symptoms completed an attention task composed of four blocks: baseline, frustration, suppression, and recovery. In the frustration and suppression blocks, negative affect was induced by false negative feedback. During the …

Elite Capture, Free Riding, And Project Design: A Case Study Of A Community-Driven Development Project In Ceará, Brazil, Jessica Carrick-Hagenbarth

Doctoral Dissertations

This dissertation explores the successes and failures of a community-driven development project, São José Agrário (SJA), conducted in Northeastern Brazil. The project was co-funded by the World Bank and the State of Ceará and co-directed by a social movement (the Landless Workers Movement, MST) and the State of Ceará. The dissertation employs a mixed methods approach based on eight case studies, a census survey of six communities, and interviews with a wide variety of actors connected to the project. I address the problem of elite capture, either by non-targeted communities or by an elite within the targeted communities disproportionately benefiting …

Do We Have A Climate For Change? Insights About Adaptation Planning Actions In Coastal New England, Ana M. Emlinger

Doctoral Dissertations

“I just drink more coffee and stay late” – declared the town planner of a small coastal community in the South of Boston, Massachusetts (MA) referring to the need of extra work to address climate change adaptation in a short-staffed planning department. These words illustrate one of the many common issues faced by planners of small and medium coastal communities in the region. A systematic incorporation of climate change concerns into formal community planning, management, and infrastructure design is in nascent stage. The challenges of effective adaptation are complex and likely to be politically hard, especially at the local level …

Three Essays On The Social Determinants Of Early Childhood Health And Development, Andrew Barenberg

Doctoral Dissertations

This three-paper dissertation examines the social determinants of early childhood and in-utero health. The first chapter examines the impact of early childhood stunting on educational outcome in Tanzania. Using the extent of third-trimester overlap with the Tanzania hunger season to create an exogenous variation in stunting, I find that a one standard deviation stunting decreases educational achievement by .88 school years compared to a child's siblings. A placebo group not affected by the hunger season is used to confirm that in-utero nutrition deprivation is the cause of the education differences. The second paper utilizes the food price shocks and price …

Acculturation Stress, Psychological And Sociocultural Adjustment, And Development Of American Adolescents: A Qualitative Study Of Newton High School Exchange Students In China, Binbin Zhu

Doctoral Dissertations

Theories from the extant acculturation literature functioned to categorize international students’ adaptation experiences and predict their acculturation outcomes. Also, relevant studies focused mainly on students at the tertiary level. For adolescent students seeking self-development toward independence and autonomy, how they negotiated their identity challenges and tensions in a cross-cultural context, and how surrounding others in their socialization impacted on their psychosocial adjustment process and transformative experiences have not been actively explored. This qualitative study approached adolescent students’ acculturation as an integrated development and learning process to explore the effects of developmental and cultural factors on their cross-cultural adaptation, especially examined …

The Role Of Adoptive Identity In Career Development Of College And Non-College Individuals, Yesel Yoon

Doctoral Dissertations

Identity development is a particularly salient developmental task that begins to take form during adolescence, and consolidation of multiple domains of identity is necessary for achieving successful outcomes in adulthood (Erikson, 1968). The purpose of this study was to examine the role of an ascribed adoptive identity on the individualization of one’s chosen career identity. Adoptive identity was examined using both individual and family-level factors, and career identity was measured across adolescence, emerging adulthood, and adulthood. The present study used a sub-sample of adoptees, adoptive mothers, and adoptive fathers from an ongoing longitudinal research study, the Minnesota/Texas Adoption Research Program …

Detecting Candidate Preknowledge Of Items Using A Predictive Checking Method, Xi Wang

Doctoral Dissertations

In on-demand high-stakes testing programs such as GRE and TOEFL, some items are repeatedly used across test administrations to reduce the cost of developing new items constantly. Item exposure provides an opportunity for examinees to have knowledge of particular test items in advance of their administration. It poses a threat to test security and ultimately will result in invalid test scores. Therefore, many testing programs conduct quality control to monitor test compromise at individual and/or group level. A predictive checking method is proposed in this study to detect examinee preknowledge on exposed items. We consider a scenario where a test …

Women, Convergent Film Criticism, And The Cinephilia Of Feminist Interruptions, Rachel L. Thibault

Doctoral Dissertations

This dissertation examines the ways in which female film critics practice film criticism in the convergent age. In original research drawn from ethnographic interviews with eight female film critics and bloggers as well as textual, historical, and reception analyses of criticism, this dissertation argues that women who write film criticism in the convergent era are not only writing from a space of marginalization based on the patriarchal dominance of the film industry, but also face a series of obstacles through gendered and discursive conflicts that are unique to writing online and which do not exert the same impact on male …

Infants' Reasoning About Agents' Identity: The Case Of Sociomoral Kinds, Hernando Taborda

Doctoral Dissertations

Recent studies in development psychology suggest that early on infants are able to distinguish characters who display a cooperative behavior from characters who display an antisocial behavior. The current research builds on these findings and aims at determining the extent to which infants possess the sociomoral distinction of “good” and “mean” agents. In particular, we propose that infants represent sociomoral behaviors through kind-based categories. This hypothesis was tested in the current research across 5 different experiments by investigating how infants represent the identity of agents in sociomoral situations. Experiment 1 used a looking-time paradigm to demonstrate 11-month-old infants’ bias to …

The Political Economy Of Smallholder Incorporation And Land Acquisition, Alfredo R. Rosete

Doctoral Dissertations

Of late, development institutions and economists have argued that one way to accomplish the modernization, and thus, poverty alleviation in the rural sector is through smallholder incorporation- partnerships between agribusiness firms and smallholders in order to cultivate high valued export crops. Smallholders in developing countries often face numerous challenges that result in low incomes, and limited opportunities. As a result of these challenges, smallholders in developing countries continue to cultivate subsistence crops, or, use less technologically intensive techniques. Thus, many are unable to maximize the use of their holdings. Agribusiness firms may provide the material inputs, infrastructure, and transport needed …

Bidirectional Relationships Between Maternal Parenting Behaviors And Conduct Disorder Symptoms In Preschool Children, Benjamin Rolon Arroyo

Doctoral Dissertations

Conduct disorder (CD) symptoms emerge in preschool children, and some evidence for bidirectional effects between maternal parenting behaviors and these symptoms has been found in school-age children and adolescents. However, the strength and pattern of these effects are unknown during the preschool years. The present study examined the bidirectional relationships between several key maternal parenting behaviors (negative affect, warmth, overreactivity, and laxness) and CD symptoms across the preschool years. Participants were 197 preschool children (M = 44.24 months, SD = 3.37; Girls = 92) exhibiting significant behavior problems and their mothers who participated in a 3-year longitudinal study. Maternal …
