Running The Health Care Marathon: An Ethnography Of A Charitable Clinic In A Rural Appalachian Community, Courtney A. Rhoades May 2018

Running The Health Care Marathon: An Ethnography Of A Charitable Clinic In A Rural Appalachian Community, Courtney A. Rhoades

Electronic Theses and Dissertations

Appalachia is characterized as being a place of health inequalities, including substandard health care access. Health disparities in access to health care persist in the region, and many Tennessee residents are unable to afford premiums, if they can afford insurance at all. Uninsured individuals rely on community based free clinics, which serve as health care safety nets and allowing people to obtain limited health care. This ethnographic investigation, involving semi-structured interviews and participant-observation of the Blackberry Spruce Free Clinic, provides insight into the continued need of health care safety net resources. This research provides a patient’s perspective on the barriers …


The Motivations And Uses Of Instagram, Rehab Althobaiti May 2018

The Motivations And Uses Of Instagram, Rehab Althobaiti

Electronic Theses and Dissertations

Instagram is revolutionary in social media and networking, but little is known about the factors, social or psychological, that motivate users to become constant users on this app. A comprehensive survey was created, 277 college-aged Instagram users responded about their motivation, attitude, purpose, and primary activities regarding Instagram. The results show that Instagram users have five fundamental social and psychological motives: social interaction, archiving, self-expression, escapism, and peeking. Results showed that males were different from females in the following areas of using Instagram: create a personal space, interact with a number of people, keep in touch with friends far away, …


Postcranial Morphology And The Locomotor Adaptations Of Extant And Extinct Crocodylomorphs And Lepidosaurs, Laura Rooney May 2018

Postcranial Morphology And The Locomotor Adaptations Of Extant And Extinct Crocodylomorphs And Lepidosaurs, Laura Rooney

Electronic Theses and Dissertations

I have collected a series of linear measurements of the postcranial skeletons of 43 extant crocodylian and lepidosaur taxa to determine if those engaging in similar locomotor behavior display similar morphology despite phylogenetic differences. Stepwise discriminant function analyses reveal reptile locomotor mode can be accurately predicted (over 80% correct) based on morphology. Semi-aquatic taxa are distinguished by a longer ischium relative to pubis length, a longer scapula relative to humerus length, and a broader acetabulum than terrestrial and arboreal taxa. Arboreal taxa display a more elongate, gracile humerus and a smaller acetabulum. This morphometric data can potentially be used to …


“All The Foundation Of The Earth Becomes Desolate” Tracing Icelandic And Anglo-Saxon Connections Through A Shared Literary Frontier, Adam E. Timbs May 2018

“All The Foundation Of The Earth Becomes Desolate” Tracing Icelandic And Anglo-Saxon Connections Through A Shared Literary Frontier, Adam E. Timbs

Electronic Theses and Dissertations

The mythology of migration is deeply integral to the medieval Germanic societies peopling Northern Europe and the island nations of the North Sea. Anglo-Saxon and Icelandic society construct their identities through a memory of migration that takes places within a frontier that is mythic and historical in scope. By surveying eco-critical components of Anglo-Saxon poems such as “The Wife’s Lament” and “The Husband’s Message” alongside the Icelandic sagas Egil’s saga and The Vinland sagas, a shared tradition of the frontier ideal is revealed.


Fm Radio Signal Propagation Evaluation And Creating Statistical Models For Signal Strength Prediction In Differing Topographic Environments, Timothy Land May 2018

Fm Radio Signal Propagation Evaluation And Creating Statistical Models For Signal Strength Prediction In Differing Topographic Environments, Timothy Land

Electronic Theses and Dissertations

Radio wave signal strength and associated propagation models are rarely analyzed across individual geographic provinces. This study evaluates the effectiveness of the Radio Mobile model to predict radio wave signal strength in the Blue Ridge and Valley and Ridge physiographic provinces. A spectrum analyzer was used on 19 FM transmitters to determine model accuracy. Statistical analysis determined the significance between different terrain factors and signal strength. Field signal strength was found to be related to test site elevation, transmitter azimuth, elevation angle, transmitter elevation, path loss, and distance. Using 76 signal strength receiver sites, Ordinary Least Square regression models predicted …


Worlds With Words: Discourse And Frame Analysis Of Performance Storytelling, Chelise Fox May 2018

Worlds With Words: Discourse And Frame Analysis Of Performance Storytelling, Chelise Fox

Electronic Theses and Dissertations

In this thesis, I explore how performance storytellers create intense focus on imaginal realities through language—a phenomenon sometimes called “transport” or “realm-shift.” To this end, recordings of performances by two professional storytellers were transcribed and examined through the lens of frame theory and discourse analysis. Examination of these transcripts shows that storytellers employ clusters of linguistic involvement strategies around frame transitions, facilitating realm-shift. Additionally, it shows that throughout a telling, tellers shape discourse around frame shifts that draw attention to significant elements, particularly those that establish a story’s relevance to the occasion of its telling and those that contribute to …


Geostatistical Analysis Of Potential Sinkhole Risk: Examining Spatial And Temporal Climate Relationships In Tennessee And Florida, Kimberly Blazzard May 2018

Geostatistical Analysis Of Potential Sinkhole Risk: Examining Spatial And Temporal Climate Relationships In Tennessee And Florida, Kimberly Blazzard

Electronic Theses and Dissertations

Sinkholes are a significant hazard for the southeastern United States. Although differences in climate are known to affect karst environments differently, quantitative analyses correlating sinkhole formation with climate variables is lacking. A temporal linear regression for Florida sinkholes and two modeled regressions for Tennessee sinkholes were produced: a general linearized logistic regression and a MaxEnt derived species distribution model. Temporal results showed highly significant correlations with precipitation, teleconnection patterns, temperature, and CO2, while spatial results showed highly significant correlations with precipitation, wind speed, solar radiation, and maximum temperature. Regression results indicated that some sinkhole formation variability could be …


Italian Domination In Complementary Prisms, Haley D. Russell May 2018

Italian Domination In Complementary Prisms, Haley D. Russell

Electronic Theses and Dissertations

Let $G$ be any graph and let $\overline{G}$ be its complement. The complementary prism of $G$ is formed from the disjoint union of a graph $G$ and its complement $\overline{G}$ by adding the edges of a perfect matching between the corresponding vertices of $G$ and $\overline{G}$. An Italian dominating function on a graph $G$ is a function such that $f \, : \, V \to \{ 0,1,2 \}$ and for each vertex $v \in V$ for which $f(v)=0$, it holds that $\sum_{u \in N(v)} f(u) \geq 2$. The weight of an Italian dominating function is the value $f(V)=\sum_{u \in V(G)}f(u)$. …


Assessing Readiness For Group Therapy In Primary Care: An Initial Survey Exploring Need, Philip Randall May 2018

Assessing Readiness For Group Therapy In Primary Care: An Initial Survey Exploring Need, Philip Randall

Electronic Theses and Dissertations

Primary care providers have become the front line of treatment for mental health in the United States. Group interventions have been argued to be an effective way to treat more patients with fewer resources, which could reduce the burden of psychopathology on primary care settings. Group therapy faces many barriers to successful implementation in primary care, including site constraints, provider perceptions, population needs, and recruiting difficulties. A survey was developed to assess primary care providers’ perspectives on these areas and distributed via online survey to practitioners in Appalachia; 28 providers responded. No hypotheses were supported, likely a result of the …


Eyring Activation Energy Analysis Of Acetic Anhydride Hydrolysis In Acetonitrile Cosolvent Systems, Nathan Mitchell May 2018

Eyring Activation Energy Analysis Of Acetic Anhydride Hydrolysis In Acetonitrile Cosolvent Systems, Nathan Mitchell

Electronic Theses and Dissertations

Acetic anhydride hydrolysis in water is considered a standard reaction for investigating activation energy parameters using cosolvents. Hydrolysis in water/acetonitrile cosolvent is monitored by measuring pH vs. time at temperatures from 15.0 to 40.0 °C and mole fraction of water from 1 to 0.750. This work utilizes a temperature controlled water bath and a Vernier glass-body pH probe with Vernier Logger Pro 3.10.1 software for automated data collection. Data analysis is used to determine observed kinetic rate constants under the assumption that hydrolysis is a pseudo-first-order reaction. Eyring plots were used to compare activation energy parameters under iso-mole fraction conditions. …


A Role Of Vitamin B2 In Reducing Amyloid-Beta Toxicity In A Caenorhabditis Elegans Alzheimer’S Disease Model, Muhammad Tukur Ameen May 2018

A Role Of Vitamin B2 In Reducing Amyloid-Beta Toxicity In A Caenorhabditis Elegans Alzheimer’S Disease Model, Muhammad Tukur Ameen

Electronic Theses and Dissertations

Alzheimer’s disease (AD) is associated with amyloid-beta peptide deposition and loss of mitochondrial function. Using a transgenic C. elegans AD worm model expressing amyloid-beta in body wall muscle, we determined that supplementation with either of the forms of vitamin B2, flavin mononucleotide (FMN) or flavin adenine dinucleotide (FAD) protected against amyloid-beta mediated paralysis. FMN and FAD were then assayed to determine effects on ATP, oxygen consumption, and reactive oxygen species (ROS) with these compounds not significantly improving any of these mitochondrial bioenergetic functions. Knockdown of the daf-16/FOXO transcriptional regulator or the FAD synthase enzyme completely abrogated the …

Electronic Theses and Dissertations

This multiple baseline single-case design study explored the influence that training in observation and interpretation had on teachers’ meaningful conversations with children. Three preschool teachers (1 from public school and 2 from Head Start) were trained using the Cycle of Inquiry System (Broderick & Hong, 2011) that informs of ways to observe and interpret children’s thinking to facilitate developmentally appropriate conversations.

Teachers documented and interpreted observations of children engaged in small group play. Teachers were surveyed pre-training and post-training about observation, interpretation, curriculum, the teacher’s role, and the purpose of teacher interactions with children. Teachers were interviewed to clarify researcher …


Relationships Between Institutional Characteristics And Student Retention And Graduation Rates At Sacscoc Level Iii Institutions, Kala Perkins-Holtsclaw May 2018

Relationships Between Institutional Characteristics And Student Retention And Graduation Rates At Sacscoc Level Iii Institutions, Kala Perkins-Holtsclaw

Electronic Theses and Dissertations

As the United States struggles to be globally competitive with the number of students completing a college degree higher education leaders continue seeking answers to improving student retention and graduation rates. Decades of research has been conducted on investigating factors that impact student retention and graduation with the majority of that research being centered on student attributes and students’ precollege characteristics. Research has been limited on institutional characteristics and their associations with student retention and graduation rates. Therefore the purpose of this study was to examine the extent that specific institutional characteristics predict first-year, full-time, fall-to-fall retention rates and 6-year …


Diel Rhythmicity Found In Behavior But Not Biogenic Amine Levels In The Funnel-Web Spider Agelenopsis Pennsylvanica (Araneae, Agelenidae), Alexander E. Demarco May 2018

Diel Rhythmicity Found In Behavior But Not Biogenic Amine Levels In The Funnel-Web Spider Agelenopsis Pennsylvanica (Araneae, Agelenidae), Alexander E. Demarco

Electronic Theses and Dissertations

Quantifying individual differences in behavior and the extent that behavior is influenced by circadian control is of paramount importance in behavioral ecology. In addition, the proximate mechanisms underlying behavior are also critical in order to obtain a more complete picture of how behavior evolves. Biogenic amines (BAs) are simple nitrogenous compounds derived from amino acids and have been consistently and extensively linked to behavior. For this study, we analyzed temporal patterns of BAs in relation to the antipredator (boldness) and aggressive behavior in female Agelenopsis pennsylvanica, a funnel-web spider. Using HPLC-ED, we compared behavioral responses to temporal patterns of …


The Effect Of Alcohol Consumption On Adipokine Secretion, Ashley Degroat May 2018

The Effect Of Alcohol Consumption On Adipokine Secretion, Ashley Degroat

Electronic Theses and Dissertations

Alcoholic Fatty Liver Disease (AFLD) is caused by excessive alcohol consumption and is a leading cause of liver related mortalities, with currently no treatments available. The goal of this project was to establish the effect of alcohol consumption on adipose tissue-derived secreted factors, adiponectin and C1q TNF Related Proteins 1-3 (CTRP1-3). We propose that excessive alcohol consumption will reduce circulating levels of adiponectin and CTRPs 1-3. Mice were fed a Lieber-Decarli control or alcohol diet for 10-days with a gavage (NIAAA model) or 6-weeks with no gavage (chronic model). Serum and adipose tissue were collected and CTRPs 1-3 and adiponectin …

The Socially Deviant (M)Other In Euripides' "Medea" And Two Modern Adaptations, Christina Faye Kramer May 2018

The Socially Deviant (M)Other In Euripides' "Medea" And Two Modern Adaptations, Christina Faye Kramer

Electronic Theses and Dissertations

For centuries male-dominated societies have developed their own culturally constructed images of the socially acceptable and socially deviant mothers. The thesis explores how the Grecian, Caribbean, and Irish cultures of Euripides’ Medea (431 BC), Steve Carter’s Pecong (1990), and Marina Carr’s By the Bog of Cats (1998) respectively, all based on the Medea myth, commonly define the social deviant (m)other and condemn her for her “otherness.” It also discusses the limitations of each society’s decision to label the Medea-figure as socially deviant. Euripides creates an impossible dichotomy between the culturally constructed concepts of heroism and motherhood, which he locates in …

Remembering The Church In The Wildwood: The Archival Processing And Digitization Of The Martinsville Baptist Church Collection, Allison N. Grimes

Electronic Theses and Dissertations

Martinsville Baptist Church was founded in 1912 in a rural farming community on State Highway 7 in eastern Nacogdoches County. The church was founded during a revival being held in the community of Martinsville and has been in continuous operation ever since. The church grew throughout its lifetime, reaching record attendance and membership numbers between 1950 and 1980. Since the early 2000s, church attendance and membership has been in decline. This thesis outlines the history of Martinsville Baptist Church and explains conservation measures taken during the archival processing and digitization of records in the Martinsville Baptist Church Collection.


Separating Self-Esteem From Self-Concept Processes: An Investigation Of Emotional Responses To Self-Image Threat, Andrew Schwarzkopf May 2018

Separating Self-Esteem From Self-Concept Processes: An Investigation Of Emotional Responses To Self-Image Threat, Andrew Schwarzkopf

Electronic Theses and Dissertations

The researcher examined self-concept/self-image and self-concept maintenance processes in response to self-image threat. Replicating previous research, the researcher hypothesized that those who had self-image threatened would not engage in derogatory behavior in order to maintain self-concept (Fein & Spencer, 1997). Participants completed a false intelligence test giving negative, neutral, or positive feedback and were given an opportunity to evaluate members of a locally stereotyped or locally nonstereotyped social group for a hypothetical job position. No significant main effects or interactions were found for feedback or applicant social group on participant evaluations of applicants, indicating that derogation did not influence judgements …

Inescapably Social: Dimensions Of Self Construction In The Virtual Social World Of Runescape, Isaac Robe May 2018

Inescapably Social: Dimensions Of Self Construction In The Virtual Social World Of Runescape, Isaac Robe

Electronic Theses and Dissertations

This thesis examines the virtual social world of the Massively Multiplayer Online Role-Playing Game, Runescape. I observed several locations in the Runescape world, conducted in-depth interviews with players, and participated in clan activities. I analyzed how individual players develop and extend concepts of self through their participation in the game. Players attach patterned meanings to in-game social objects, particularly their character (avatar) that mediates their experiences in the game. Many players refer to their character’s appearance and accomplishments as an extension of the self, particularly when they master game skills or accumulate in-game wealth. How players spend and think about …

The Talk: Christian Right And Liberal Left Rhetoric About Sex Education, True Neal May 2018

The Talk: Christian Right And Liberal Left Rhetoric About Sex Education, True Neal

Electronic Theses and Dissertations

This thesis examines the rhetoric surrounding sex education crafted by two major types of advocacy groups: the Christian Right and the Liberal Left. I conducted a qualitative analysis of content on sex education produced by six high-profile organizations: The Heritage Foundation, Family Research Council, Focus on the Family, American Civil Liberties Union, the Guttmacher Institute, and Planned Parenthood. I found that these polarized organizations do not debate each other; instead, they focus on parents whose political leanings match their own. Sex education is at the center of other issues that also divide the Christian Right and the Liberal Left: healthcare, …
