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 …

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.

Transgender Self-Attitudes: Formation And Change A Qualitative Study, Juliet Ezhil Meggs

Doctoral Dissertations

The current study explored attitudes of transgender people about being transgender and how these attitudes had formed and changed over participants’ lifetimes. Using a qualitative, grounded theory approach (Charmaz, 2003), interviews with 11 transgender adults were coded and analyzed. Two primary categories of attitudes were identified: participant attitudes regarding acceptability of being transgender and attitudes regarding how possible they believed it is to be transgender and/or transition genders. Early in life, most participants had little exposure to the idea of being transgender, and those that knew of it often initially believed that it would too difficult or impossible to transition. …

Physical Home Environment, Personal Competencies, And Psychological Well-Being Of Community-Dwelling Older Adults: Development Of A Structural Model, Shannon Marie Trecartin

Doctoral Dissertations

This multi-manuscript dissertation focuses on the relationships between the physical home environment, personal competencies, and psychological well-being among older adults living in community settings. The ecological model of aging serves as the guiding theoretical framework for the exploration and design of the subsequent studies. The first paper is a critical review of the literature. Results suggest that there is little consistency in the measurement of the physical home environment across studies. Also, more research is needed to clarify the relationships between the three major constructs and to expand the area of study to U.S. populations. Finally, some support exists to …

Attitudes And Barriers To Women’S Participation In A Proposed Community-Based Conservation Program In Western Belize, Amanda Shay Kaeser

Doctoral Dissertations

World conservation issues have been addressed in many ways around the world. The use of community-based conservation (CBC) as a method to reduce harmful practices has gained in popularity in the past few decades. This dissertation reports results from a pre-analysis of a proposed CBC program in western Belize. Through qualitative interviews with 47 stakeholders, and a quantitative survey with 486 Belizean women, we determined that a CBC program designed especially for women should be successful. Some of the aspects of a program that women expressed a desire for was more conservation and forest education. However, contrary to our assumption …

Modeling Prehistoric Health In The Middle Cumberland Region Of Tennessee: Mississippian Populations On The Threshold Of Collapse, Christina Laiz Fojas

Doctoral Dissertations

This research explores differences in mortality and survivorship resulting from factors associated with the abandonment of the Middle Cumberland Region (MCR) of Tennessee during the Mississippian period (ca. 1000-1500 AD). My dissertation investigates whether individuals from the Late Mississippian period had a greater risk of death than individuals from the Early Mississippian period. Adult age-at-death estimates (n=545) were calculated using Transition Analysis, a Bayesian maximum likelihood method. Gompertz and Gompertz-Makeham hazard models were utilized to reconstruct the mortality profile of the MCR as they model human adult mortality and generate robust parametric mortality profiles. Rather than recount the prevalence of …

The Evaluation And Refinement Of Nonmetric Sex And Ancestry Assessment Methods In Modern Japanese And Thai Individuals, Sean D. Tallman

Doctoral Dissertations

Effective biological profiles in forensic anthropology and bioarchaeology depend on the development, validation, and refinement of population-specific methods. However, most methods were developed in North America on individuals of African and European descent, and it is unlikely that such methods can generate accurate biological profiles for Asian individuals. Moreover, Native Americans have served as biological proxies for Asians due to their distantly shared genetic history, resulting in largely untested assumptions that Native Americans and Asians are homogenous and share nonmetric sexually dimorphic skeletal features and a unique suite of cranial traits that can be used in ancestry assessment.

This study …

Essays On Environmental Policy Instruments, Emissions Leakage And Public Policy, Shreekar Pradhan

Doctoral Dissertations

This dissertation consists of three essays related to my research on environmental policy, emissions leakage, and public policy. In the first essay, I address how open economies respond to environmental policy instruments under uncertainty. I develop a dynamic stochastic general equilibrium model for a small open economy (SOE) and evaluate the macroeconomic fluctuations in response to cap-and-trade, pollution tax, and emissions intensity standard under two shocks: productivity and terms of trade. My findings suggest that cap-and-trade policies are most effective in dampening the macroeconomic volatility from productivity shock. However, under the terms-of-trade shock, pollution tax, and intensity target policies are …

Burnout And Attrition Experiences Of New Professional Clinical Mental Health Counselors: An Application Of The Indivisible Self Model Of Wellness, Adam Forrest Stephens

Doctoral Dissertations

Professional burnout is a phenomenon common to professionals working within the helping fields (Figley, 2002). Though common, little exists in the way of formal theories to define and understand the phenomenon and how it may be understood in a progressive, developmental sense (Paris & Hoge, 2010). To date, burnout has primarily been understood and researched through the study of other constructs that fit within the global definition of burnout (Newell & MacNeil, 2010), as well as more constructivist approaches to the phenomenon, stating there are no predictive cycles or types of experiences that result in a perceived sense of professional …

Essays In Policy Analysis, Michael Philip Craig

Doctoral Dissertations

My dissertation consists of three essays related to policy analysis. In the first essay we ask, how can developing nations who face revenue mobilization issues and large informal sectors use taxation as a means of nation building? To answer this, we design a dynamic general equilibrium model that accounts for a large informal sector. Contrary to previous studies that model the informal economy, we focus on the importance of the government maintaining its social fiscal contract with its constituents by including the provision of productive public goods in the model. By doing so, we show that increasing taxes can be …

Out From Darkness And Into The Light: The Role Of Transparency And Social Media In Government, Frances Nichols Bachstein

Doctoral Dissertations

Government agencies that protect secrecy often have a difficult time connecting to the public. Secretive, or perceived secretive government organizations often fall into the nebulous realm of uncertainty for the information consumer. This results in a great deal of misinformation and disinformation being thought of as correct. Since 2008, the US government is moving toward a more transparent, open, and easily accessed information base through social media. Agencies across the government are adopting types of social media communication. However, bureaus that primarily focus on security and safeguarding secrets struggle with how much disclose, which platforms of social media are the …

Using Spatial Analysis To Evaluate Fire Activity In A Pine Rockland Ecosystem, Big Pine Key, Florida, Usa, Lauren Ashley Stachowiak

Doctoral Dissertations

Pine rocklands are fire-prone ecosystems with limited spatial extent, and have experienced reduced area in the previous decades through habitat conversion and urbanization. The purpose of this dissertation research was to evaluate the historical range of variability of fire activity and spatial patterns of fires in a pine rockland ecosystem in the National Key Deer Refuge (NKDR) on Big Pine Key in the Lower Florida Keys. To investigate the temporal and spatial patterns in fire activity, I (1) evaluated the temporal patterns for fires in my study area in the NKDR, (2) analyzed differences in standard fire history metrics since …

New Perspectives On The Seventeenth-Century Protohistoric Period In East Tennessee: Redefining The Period Through Glass Trade Bead And Ceramic Analyses, Jessica Nicole Dalton-Carriger

Doctoral Dissertations

The Protohistoric period in East Tennessee is poorly understood in the archaeological record and is defined as the intermediate period between the Late Mississippian and Historic periods in the seventeenth century. Earlier research focused on depopulation, population replacement, and the rise of Overhill Cherokee settlements in the eighteenth century, with little attention to the transitional Protohistoric period. The goal of this dissertation is to examine new fields of evidence and employ new dating methods in order to fully understand the Protohistoric period in East Tennessee

This dissertation does this in three ways. It explores three hypotheses concerning the habitation of …

The Environmental Effects Of Trade And Environmental Policy Within And Across Sectors, Lawrence Dale Laplue Iii

Doctoral Dissertations

In the first chapter of this dissertation I analyze how establishment-level choices and dynamics affect aggregate emissions outcomes. To do this I first decompose aggregate emissions into three channels: scale or country size, composition or sector market share, and aggregate technique or emissions intensity. I then extend the decomposition to show how the aggregate technique channel is driven by four establishment-level channels: entry, exit, reallocation of resources between survivors, and within-establishment adjustment of production techniques and emissions intensity. Using establishment-level emissions data and a unique empirical exercise I first show, empirically, how the relative importance of the composition and aggregate …

The Tasks Of Elected Officials Within The Policy Process Of Interlocal Cooperation, Stephen Matthew Adkins

Doctoral Dissertations

Interlocal cooperation provides local governments with a third means of service provision, after direct provision and contracting out, that allows problems to be addressed at the regional level. Much of the academic literature on this topic places appointed officials as those who take the lead role in these types of arrangements. This research explores the involvement of elected officials, specifically city mayors, in interlocal cooperation. Based on 64 responses from mayors in the southeast region, this research finds statistically significant relationships between mayoral comfort level with tasks associated with interlocal cooperation and a number of variables including city size and …

Essays In Applied Economics: Applications Of Transformed Ordinal Quantile Regression, Okila R. Elboeva

Doctoral Dissertations

This dissertation consists of three essays on the application of Transformed Ordinal Quantile Regression (TORQUE) developed by Hong and He (2010). TORQUE is based on jittered response, a nonparametric link function, a semiparametric quantile estimation. When the response variable is categorical an application of the standard quantile regression is not optimal. TORQUE technique generalizes ordinary quantile regression, and as a semiparametric method it is more robust than Maximum Likelihood Estimators.

In the first essay I estimate conditional quantiles of happiness using the data from British Household Panel Survey (BHPS) for 2006. I find the continuity assumption of happiness ranking does …

Understanding Perceptions Of Breast Health In A Southern Appalachian Community, Hannah Leigh Shinault

Doctoral Dissertations

Culture is central to how individuals perceive and understand health. Thus, the Appalachian culture impacts how Appalachian women perceive and maintain breast health. Using information about the broader Appalachian region and the Southern Appalachian sub-region, specifically, as well as the existing body of literature about cancer, culture, and communication theory, this qualitative study describes breast health from the point of view of women and health information providers in this region in order to better communicate about breast health maintenance practices.

Results from this study will allow individuals working with breast cancer patients and prevention to better understand how cultural identity …
