The Feminomenon Of Athletic Band Directing: A Multiple Case Study, Sydney Leigh Rush

Electronic Theses and Dissertations

Women represent a small fraction of leadership within two traditionally male-dominated fields: collegiate band directing and the marching arts (Foley, 2019; Gould, 2001; Rush, 2023). In 2015, approximately 21% of high school band directors were female and 79% were male (Yoder, 2015). Further, the CMS Directory of Music Faculties (2017 – 2018) revealed women held only 11.3 percent of all collegiate band director positions in the United States (Shaker, 2020). In 2023, women accounted for less than 6% of Directors of Athletic Bands for Football Bowl Subdivision (FBS)- Division 1, four-year universities (Rush, 2023). Although research has been done regarding …

Hidden Markov Model For Identifying Local Variants In Human Genomes Using Simulated Data, Scott Mccallum

Electronic Theses and Dissertations

Identifying adaptive mutations in genetic data is challenging due to the low frequency of occurrence of such events, and because signatures of selection are intertwined with the footprints of various other evolutionary forces that shape our genomes. Even when a larger region appears to be under selection, genomic sites that are linked to adaptive mutations have similar statistical signals, and thus can obfuscate the identification of the actual adaptive mutation. The new method described here uses a Hidden Markov Model that allows for classification of neutral, linked, and sweep (adaptive mutation) genomic sites. This model is general and can be …

Racial Identity & Psychological Distress: The Mediating Role Of Sense Of Community And Spiritual Struggles Among Black Christians., Adebayo Ajibade

Electronic Theses and Dissertations

Religious practice and church membership have historically been protective and critical in Black communities in the United States and across the African diaspora. Demographic studies have shown a consistent decline in religious adherence and practice across racial and ethnic groups in the United States. However, the decline in religious practice and participation in religious communities has been less pronounced among individuals of African descent. Participation in one’s religious community is often a source of positive social engagement and can foster positive intrapersonal outcomes (e.g., wellbeing). However, religious communities and religious practice can also be the source of conflict and emotional …

Cost Saving And Resource Limited Public Health Interventions In Southeast Asia, Amanda Blackwelder

Electronic Theses and Dissertations

Background: Public health interventions are any activity with the objective of improving human health such as preventing or curing disease, reducing the severity or duration of a disease, or assisting in regaining function after a disease or injury. These interventions are known to be impactful; however, those living with the highest burden of disease such as individuals in low- and middle-income countries have limited money and resources to successfully implement these interventions. Southeast Asian countries are among some of the middle-income countries effected by the lack of affordable interventions. The aims of this study were to assess cost saving and …

Evaluating Deterministic Approaches To Forecast Population By Educational Attainment In The United States, Wei Gu

Electronic Theses and Dissertations

Forecasting population by educational attainment not only benefit government planning on allocating educational resources, labor market demand, and long-term human capital and overall well-being of society (Lutz et al. 2008), but also help predicting size and structure of future population (Lutz and KC 2011). To seek effective method to produce precise results with limited resources, this dissertation compared the Cohort Component Method (CCM) and Hamilton Perry (HP) method to forecast population that are 25 years and older with Associate’s degree and above, and evaluated how factors may impact the accuracy, and how factors interact with each other to influence the …

Loggerhead Shrike Detectability And Occurrence In Coastal South Carolina Urban Areas, Michelle Krauser

Electronic Theses and Dissertations

Grassland birds, such as the loggerhead shrike (Lanius ludovicianus), are threatened by extensive land-use change, including urbanization. Loggerhead shrikes have been declining since the early 1900s and are rare or extirpated in portions of their former range. Obtaining reliable population estimates of loggerhead shrikes is important to identify demographic trends and ensure conservation decisions are based on an accurate assessment of their current status. Imperfect detection, or the inability to detect every shrike during a survey, can result in biased population estimates. Estimating detection probability is labor-intensive and requires assumptions that are difficult to satisfy in most field studies. Understanding …

Child Exit Types And Permanency Outcomes In Foster Care As Correlated To Casa Involvement, Grace Elizabeth Hill

Electronic Theses and Dissertations

This study sought to identify correlations between Court Appointed Special Advocate (CASA) activities and exit outcomes for children in foster care. Previous research on the impact of CASA has been inconclusive and offered mixed findings, so this study sought to build off of previous research while also exploring new areas of research that have not yet been investigated. Big Country CASA’s database, Optima, was utilized to retrieve data on cases that closed during the 2021 fiscal year (September 1, 2020, to August 31, 2021). This yielded a sample size of 75 cases. Through an analysis of these cases to test …

Developing, Refining, And Testing The Intersectional Model Of Service Use: A Transgender And Nonbinary-Specific Model Of Healthcare Access, Jarrod Call

Electronic Theses and Dissertations

Transgender and nonbinary (TNB) people are more likely to experience negative health outcomes than cisgender (i.e., not TNB) people, but less likely to access healthcare services due to the systemic forces of transphobia and cisgenderism. Despite this, there are few theoretical models of healthcare access specifically designed for TNB people. This three-paper dissertation addresses this gap by developing, refining, and testing the Intersectional Model of Service Use (IMSU), a population-specific framework for researching TNB healthcare access. Manuscript one describes how the initial IMSU was developed from an integrative review of currently available TNB healthcare access literature. This initial IMSU was …

Rural Npo Leadership In Time Of Volatility: A Study Of Nonprofit Organizations In South Dakota, Mellissa Heermann

Electronic Theses and Dissertations

This exploratory study determined the legitimacy of the leadership gap in Nonprofit Organizations (NPOs) in South Dakota by collecting quantitative and qualitative data and then comparing the results with national studies. It aimed to understand if NPOs were more vulnerable to leadership transitions and the costs associated with them. It also provided additional insight for future research opportunities. While there were studies on larger NPOs, such as the United Way, or NPOs in more highly populated regions, there was a gap in research for rural NPOs that potentially would not be financially able to research these trends on their own. …

A Longitudinal Examination Of Biomechanical Balance And Quantitative Multidomain Assessments During Recovery Following Sport-Related Concussion, Moira Kate Pyrhoda

Electronic Theses and Dissertations

Sport-related concussion is an inherent risk to athlete health in contact and collision sports. Both short- and long-term risks are associated with the injury. Short-term, athletes may develop post-concussion syndrome (PCS), the persistence of cognitive, physical, and emotional symptoms for weeks or months after injury. Athletes who return to play (RTP) prematurely are at increased risk for lower extremity injury and repeated concussion injuries. Long-term, history of multiple concussions have been linked to neurodegenerative diseases. Due to these risks, concussion assessments must be sensitive to the injury and useful in the diagnosis, recovery, and RTP phases of the injury.

The Examination Of A Mobile Application For The Reduction Of Posttraumatic Stress Related Symptoms In Emergency Dispatchers, Emy Willis

Electronic Theses and Dissertations

Emergency dispatchers report that their jobs are stressful, yet there are few controlled investigations examining their specific psychological complaints. Additionally, research examining the use of interventions directed at alleviating their work-related stress is limited. This study aims to examine the efficacy and feasibility of a mobile application (PTSD Coach) on various indicators of psychosocial well-being among emergency telecommunicator dispatchers. A sample of 117 emergency dispatchers completed self-report psychological mood assessments at baseline, weekly for five weeks during PTSD Coach use and post-treatment. Participant report of psychological symptoms showed statistically significant decreases in mood severity over the period of one month.

Variation In Prospecting Behavior And Drivers Of Post-Fire Habitat Preference Among Juvenile Florida Scrub-Jays, David Sherer

Electronic Theses and Dissertations

Florida Scrub-Jays (Aphelocoma coerulescens, FLSJ; federally Threatened) are cooperatively breeding birds endemic to Florida and dependent on fire-maintained xeric oak scrub. FLSJs are year-round residents, highly territorial, and rarely disperse far from their natal territory. Lifetime reproductive success is highest among individuals breeding in early-successional habitat, usually less than 9 to 10 years post-fire. However, because scrub burns infrequently such early-successional, high-quality habitat is extremely limited and competition for it as breeding space is likely intense. Because some birds live long enough to experience habitat succession, FLSJs also occupy later-successional overgrown scrub, even though both survival and fecundity decline. Although …

A Phenomenological Study Of High School Assistant Principals Who Supervise Special Education, Erin Vacchio

Electronic Theses and Dissertations

This phenomenological study examined the lived experiences of high school assistant principals who lead the Exceptional Student Education (ESE) departments at their respective schools. The role of the school leader is critical and complex. Second to only the classroom teachers, school leaders have the ability to shape the school wide attitude and vision for students with disabilities. Knowing that in the past 30 years, the number of students with disabilities has nearly doubled in size, the expertise of school leaders in special education must also increase. Research on the experiences of high school administrators who serve students with intellectual disabilities …

An Assessment Of The Factors That Increase The Likeliness Of Hispanic Students To Attend Higher Education In Northeast Tennessee, Denise Chavez Reyes

Electronic Theses and Dissertations

From 2000 to 2014 the number of Hispanics grew 230%, representing an 8.6% of the national's youth (Tennessee Higher Education Commission, 2016). Although the population is growing, the educational attainment does not reflect this growth. This research tries to identify what factors influence individuals' decision to pursue higher education in rural Tennessee. Intrinsic (grit, hardiness, and motivation to lead) and extrinsic factors (Status in the U.S., caregivers’ education, involvement in high school and others) were explored. Sixty-six complete responses were submitted to our online survey. Hypothesis testing with Pearson chi-square, difference of means (ANOVA and two sample t-test), and correlational …

Seasonal Occurrence, Relative Abundance, And Migratory Movements Of Juvenile Sandbar Sharks, Carcharhinus Plumbeus, In Winyah Bay, South Carolina, Caroline Collatos

Electronic Theses and Dissertations

Winyah Bay, located on the coast of South Carolina, is the fourth largest U.S. estuary by discharge rate (Voulgaris et al. 2002), and provides an annually used habitat for juvenile C. plumbeus (Abel et al. 2006, Gary 2009). From May to September 2016 and 2017, we set a total of 303 bottom longlines in middle and lower Winyah Bay to assess sex ratios, size distributions, and catch per unit effort (CPUE), as well as the potential influence of abiotic parameters on CPUE. A subset of eleven juvenile C. plumbeus was tagged with VEMCO (V16-4H) acoustic transmitters to analyze seasonal occurrence, …

Uncovering Exceptional Predictions Using Exploratory Analysis Of Second Stage Machine Learning., Aneseh Alvanpour

Electronic Theses and Dissertations

Nowadays, algorithmic systems for making decisions are widely used to facilitate decisions in a variety of fields such as medicine, banking, applying for universities or network security. However, many machine learning algorithms are well-known for their complex mathematical internal workings which turn them into black boxes and makes their decision-making process usually difficult to understand even for experts. In this thesis, we try to develop a methodology to explain why a certain exceptional machine learned decision was made incorrectly by using the interpretability of the decision tree classifier. Our approach can provide insights about potential flaws in feature definition or …

Honors program participation was defined as completing 12 or more credit hours of honors-level course work. The population for this study included 452 honors-eligible participants with 95 honors participants (HPs) and 357 non-participants (NPs) from a community college in Tennessee. The sampling frame was generated using a five-year participation window from 2008 through 2013. Propensity score matching alleviated the threat to validity for self-selection bias …

Race, Retreat, And Refuge: Black Voices, American Nature Writing, And Ecocritical Exile, Bryon Patrick Williams

Electronic Theses and Dissertations

While existing scholarship has begun to recognize the extensive environmental experience of African Americans during the nineteenth century, black-authored environmental writing from the era is conspicuously scant in studies and anthologies into the present, even in volumes devoted to ecocritically-inflected texts by authors of color. My dissertation argues that contemporary, racially-aligned divides and gaps in environmental discourse have roots in the 1840s and 50s, when the nature writing genre coalesced into its most enduring form in the works of Henry David Thoreau, literary artist turned cultural icon. This key era—during which black Americans were frequently subject to systematic deprivation of …

Factors Influencing Healthy Eating And Physical Activity Behaviors Of Adolescents In Appalachia, Natalie Walker

Electronic Theses and Dissertations

This study examined the TPB constructs of attitude, perceived behavioral control, and subjective norms and their ability to predict healthy eating and physical activity behaviors among adolescents living in Southern Appalachia. The study also considered the relative utility of subjective norms and social support in predicting these behaviors. Data for this research were derived from a larger study, Team Up for Healthy Living, conducted September 2011 through November 2014 with high school students in the Appalachian region (Study ID: R01MD006200 from the National Institute on Minority Health and Health Disparities). Participants (n=963) completed a three-part paper survey collecting data about …

The state of Utah has sexual assault rates consistently higher than the national average. Following sexual assaults, victims are advised to seek health care services with evidence collected and packaged in sexual assault kits (SAKs). This large (N=1,874), retrospective study examined rates of sexual assault kit (SAK) submissions by law enforcement (LE) to the state crime laboratory for analysis at four sites in Utah with established sexual assault nurse examiner (SANE) programs on SAKs collected from 2010 to 2013. Variables of legal and extralegal characteristics in sexual assault cases were explored through GEE modeling to determine what factors predicted SAK …

Macgillivray's Seaside Sparrow (Ammodramus Maritimus Macgillivraii) Breeding Biology & Population Density At Tom Yawkey Wildlife Center, Yianni P. Laskaris

Electronic Theses and Dissertations

MacGillivray's Seaside Sparrow (Ammodramus maritimus macgillivraii) is a coastal marsh species sensitive to habitat alteration and threatened by coastal wetland loss. Data on seaside sparrow distribution, breeding success, and critical habitats are lacking in South Carolina. To better understand the demographics and incubation behavior of the species, I monitored breeding success, densities, song output, and presence of predators at three 7-hectare plots at the densest known population in the state. I also placed temperature data-loggers in a subset of nests to discern any links between incubation behavior and nest fate. Densities varied from a low of 5 birds/ha in a …

Organizational Strategies For Addressing Disparities Among Marginalized Older Adults, Jennifer L. Martin

Electronic Theses and Dissertations

As the United States older adult population expands, it is also becoming more diverse in terms of race, ethnicity, and sexual orientation (U.S. Census Bureau, 2010). This increased diversity necessitates that social workers research issues of cultural competency at the organizational level to ensure that community based organizations are able to meet the unique needs of a heterogeneous population of American elders. This qualitative study utilized a modified grounded theory approach to conduct individual interviews and focus groups with over 25 community based organizations serving diverse elders. This study also included analysis of over 100 agency documents, such as mission …

A Phenomenological Investigation Of The Lived Experiences Of African American Adults In Individual Mental Health Counseling, Jessica Martin

Electronic Theses and Dissertations

African Americans continue to access non-emergency mental health care at a lower rate than White Americans, despite have equal risk for mental health issues. Currently, literature in counseling focuses on this deficit and why African Americans do not attend counseling, as opposed to those African Americans who do choose to go into counseling. The purpose of this heuristic phenomenological study was to investigate the lived experiences of adult African American mental health counseling clients. Two types of purposive sampling, criterion and snowball, were used to identify and recruit participants. Six African American women were selected for inclusion in this study. …

Factors Impacting Success In Ninth Grade Algebra I For High School Students, James M. Lamie

Electronic Theses and Dissertations

The implementation of the Common Core State Standards (CCSS, 2013), No Child Left Behind Act of 2001, and the Race to the Top initiative of 2009 has placed a greater emphasis on high stakes testing. A renewed emphasis on math education for all students and their ability to succeed in high school mathematics place new challenges on today’s classroom teachers. Although the belief is that with new standards and best teaching strategies students will improve their test scores, there are multiple factors that can serve as deterrents to the success in mathematics for at-risk high school students (Balfanz, 2009). The …

Out Of This World: Hearing Indigenous And Immigrant Music In The American South, Jake Xerxes Fussell

Electronic Theses and Dissertations

At a moment when scholarship regarding traditional music in the U.S. South attempts to transcend outdated confines and limitations, the region itself experiences significant and unforeseen demographic changes. These cultural shifts call into question the foci of documentary efforts and trigger a reassessment of the study of "southern music." This project looks to the longstanding omission and ignorance of both American Indian and immigrant musical forms from the documentation and study dedicated to the region's important performative traditions. Specifically, the continued neglect of the fiddle tradition of the Choctaw Indians, an ongoing musical custom which this southeastern cultural group has …

Juvenile Ornamentation: Its Evolution, Genetic Basis, And Variation Across Habitats, Angela Tringali

Electronic Theses and Dissertations

Ornamental traits are considered honest advertisements of fitness, and their evolution is usually explained in terms of sexual selection. This explanation remains unsatisfactory in some instances, for example, juvenile birds whose plumage is molted prior to adulthood and breeding. I first evaluate whether juvenile plumage reflectance signals dominance status in the Federally Threatened Florida scrub-jay (Aphelocoma coerulescens) using a combination of observational and experimental methods. Then I estimate the heritability, non-genetic maternal and environmental effects, and strength of selection on juvenile plumage reflectance using archived feather samples and a pedigree constructed from historical nest records. Finally, I compare plumage reflectance …
