Leadership Strategies And Multi-Frame Thinking Of Rural School Superintendents’ During Periods Of Crisis, Steven J. Moses

Theses and Dissertations--Educational Leadership Studies

This dissertation examined the leadership strategies used by rural, public-school superintendents in the Central Appalachian region of Eastern Kentucky during and following the flood of 2022 that was considered a natural disaster. The context of this study was framed by a 1 in 1000-year flooding event that devastated school districts and communities in Eastern Kentucky. The geographic boundaries of this study were limited to school districts that were part of counties identified as “Appalachian” by the Appalachian Regional Commission (ARC). In addition, school districts in this study were also identified as rural by the National Center for Education Statistics (NCES) …

The Influence Of Independent Secondary School Heads On Shaping Organizational Culture, Ian D. Macphail

Theses and Dissertations--Educational Leadership Studies

This dissertation examined the experiences and connections between head of school leadership and culture in small, independent boarding schools in New England. This study was the result of the participation of eight heads of school from eight separate institutions, engaging in semi-structured interviews. All of the schools were secular in their practice, all-gender, and had a formal dormitory-based boarding program. Each school enrolled 400 or fewer students, focusing the impact of these leaders on a tighter, interactional lens. This study explored a relatively under-researched area of K-12 education and used exploratory, qualitative methods to gather the stories of these formal …

Shaping College Habitus: An Exploration Of The Effect Of The Social/Spatial Construction Of First-Year Classes On The Habitus Of Low-Income, Working-Class Rural Students, Joshua R. Mcconnell Parsons

Theses and Dissertations--Educational Policy Studies and Evaluation

Low-income, working-class (LI/WC) students entering spaces of higher education often face completely new social and cultural fields that do not match their prior experiences, requiring them to construct new conceptualizations of their habitus within those spaces—the way they internalize and interact with the world. However, a dearth of research exists on how these students’ conceptualizations of the social and physical spaces that make up their actual classroom and academic experiences play a role in how they come to form their new identities or habitus. This in-depth qualitative analysis of students’ habitus formation leverages Doreen Massey’s theoretical framework of critical spatiality …

The Effect Of Visual Signaling On Psychomotor Learning: An Explanatory Mixed Methods Study In Physical Therapy Education, Julie Pfeiffer

Theses and Dissertations--Education Sciences

The signaling principle states that people learn better when cues are used to highlight important information in a multimedia presentation. Prior research has shown that visual signaling improves learning by directing the learner’s attention to the relevant information of the instruction, improving the learner’s ability to select essential words and pictures. While the visual signaling principle has been applied to learning in the cognitive domain, the effect of visual signaling on learning within the psychomotor domain is limited. The purpose of this study is to investigate the effect of the signaling principle on learning psychomotor skills from multimedia instruction, specifically …

Student Loan Debt: Exploring The Economic Influences On Federal Student Loan Default For Students That Attended Public, Two-Year Institutions, Brian Perry

Theses and Dissertations--Educational Policy Studies and Evaluation

Over the past 30 years, a shift occurred in higher education that saw more of the burden for paying for postsecondary education placed on students. Combined with rising tuition and fees, this has led students to take on increasing amounts of student debt. Despite the historic rise in student loans, surprisingly little attention has focused on those students who default on their student loans. Additionally, the academic literature on student loans has predominately focused on traditional students at four-year institutions, despite the fact that nearly half of all undergraduates attend public two-year institutions. Finally, those studies that include economic factors …

Through a mixed-methods approach—comprising surveys, semi-structured interviews, and focus groups—the study examines the perspectives of key stakeholders, including DEI administrators, non-DEI administrators, and executive-level leaders.

The research identifies how institutional roles and positionality shape stakeholders' engagement with data and their ability to implement DEI-informed strategies. Key findings highlight discrepancies in data access, interpretation, and application, …

Increasing Expectations For Entry: Analyzing Changes In Labor Market Entry-Level Education Requirements Over Time With Potential Implications For Credential Or Degree Inflation And Returns-To-Education, William Nicholas Grinstead

Theses and Dissertations--Educational Policy Studies and Evaluation

The dissertation asks the following question: Have occupations increased academic degree requirements over time?

The literature review provides background on the origin and criticisms of the concept of a “knowledge economy.” It addresses economic “signaling theory” and sociologic “credentialism.”

The methodology relies on a trend analysis using the Bureau of Labor Statistics (BLS) Occupational Outlook Handbook and the occupations’ Standard Occupational Classification (SOC) system and its predecessor the Dictionary of Occupational Titles (DOT). In order to address whether occupations have increased academic degree requirements over time, this dissertation will compare entry-level education requirements for BLS SOC occupations that today are …

Black Girl Wisdom: A Black Feminist Analysis Of Success Strategies Of Professional African American Women At Predominately White Higher Education Institutions, Teasia Jordan

Theses and Dissertations--Educational Policy Studies and Evaluation

This phenomenological study examines the success strategies employed by professional African American women (AAW) at predominately white higher education institutions (PWIs). Grounded in Black Feminist Thought (BFT), the “Outsider Within” framework (Collins, 1986), and the concept of “failed citizenship” (Banks, 2017), it explores how AAW navigate and redefine success within environments shaped by exclusionary white patriarchal norms. Through interviews with ten co-laborers, two themes emerged: liberation from unsupportive environments and negotiation strategies to define success.

Findings reveal that AAW’s success strategies center on identity, self-awareness, and rejecting institutional oppression. Co-laborers articulated their liberation by naming the environment as oppressed, fostering …

The Aesthetics Of Environmental Risk In Paolo Bacigalupi’S The Windup Girl And The Water Knife, David Schwartz

Theses and Dissertations--English

Any work of environmentally oriented fiction that seeks to represent the wide-reaching effects of climate change is faced with the problem of scale. These texts must render visible change which is at once ubiquitous and microscopic, along with the cascade of side-effects generated in the wake of rising temperature, rising sea levels, and winnowing biodiversity. In short order, these texts must fully imagine what it means to live within the modern global risk society. Borrowing this sociological model from the late Ulrich Beck, I analyze the literary work of Paolo Bacigalupi, one of the foremost authors in the growing genre …

Effects Of Unilateral Lower Limb Suspension On Quadriceps’ Structure And Contractile Function, Eve N. Elmore

Theses and Dissertations--Kinesiology and Health Promotion

BACKGROUND: Muscle unloading such as bed rest or space flight decreases strength and cross-sectional area concomitant with a slow-to-fast fiber type shift, of anti-gravitational muscles such as the quadriceps. Diffusion tensor imaging (DTI) quantifies tissue anisotropic properties such as Fractional Anisotropy, Mean Diffusivity, Axial Diffusivity, and Radial Diffusivity, as well as muscle volume, fascicle length, and physiological cross-sectional area, and has recently been adapted to assess skeletal muscle structure. In skeletal muscle, anisotropic properties correlate with muscle fiber type and contractile function and may be responsive to unloading-induced atrophy.

PURPOSE: To assess the changes in quadriceps’ size, anisotropy, and contractile …

An Investigation Of Body Image And Eating Behaviors In Former Ncaa Heptathletes, Claire Bailey

Theses and Dissertations--Kinesiology and Health Promotion

Research consistently supports associations between body image dissatisfaction and disordered eating pathologies in collegiate athletes (e.g., Reel & Voelker, 2012; Sundgot-Borgen, 1994). More specifically, female NCAA athletes report feeling torn between peak performance body composition and body fat levels fitting ideal feminine standards (Beckner & Record, 2016; Carson et al., 2020). Examining track and field, most event groups hold a lean-promoting perspective. However, heptathletes warrant further investigation due to the multifaceted and contradictory nature of events. Specifically, heptathletes encounter complex pressures training for a wide range of physical demands, which can create confusion in expected body types (Heazlewood et al., …

Influence Of Deception Of Task Duration On The Sex-Specific Physiological, Neuromuscular, And Affective Responses To Rpe-Clamp Cycle Ergometry, Pasquale Succi

Theses and Dissertations--Kinesiology and Health Promotion

Several theories exist to explain the interaction of sensory afferent feedback and efferent feedforward signals on the generation of a rating of perceived exertion (RPE) which influence endurance exercise pacing and performance. Within these theories, exists the premise that the expected duration of exercise plays a role within the generation of an individual’s RPE and their endurance performance. Previous work has demonstrated equivocal findings of this influence, while other research has suggested potential differences between males and females. However, an RPE-clamp model, where the external workload is modulated to maintain a constant perceptual intensity, has not previously been used to …

Effect Of On-Duty Resistance Training On Neuromuscular Function In Structural Firefighters, Jamal L. Thruston

Theses and Dissertations--Kinesiology and Health Promotion

Participation in on-duty exercise is critical to enhance firefighter safety and readiness. However, these sessions are often interrupted with emergency responses and require firefighters to work in a fatigued state that may increase injury risk. Therefore, the purpose of this study was to assess the impact of on-duty resistance training on neuromuscular function. A sample of 18 firefighters (Age: 38.8±8.0yr; Body fat: 24.9±7.0%) completed 3 testing sessions, separated by at least 72 hr to compare the effects of circuit (CT) versus heavy resistance training (HRT) fatigue on neuromuscular function. During Session 1, anthropometrics and familiarization trials of balance and neuromuscular …

Understanding Intention And Behavior Of Practicing Yoga Through The Lens Of Theory Of Planned Behavior Specifically In Rural Communities; A Qualitative Study, Shelley Meyer

Theses and Dissertations--Kinesiology and Health Promotion

While there are known health benefits for participating in yoga, little has been studied on the intention and behavior for why individuals practice yoga especially through a theoretical lens and intense qualitative thematic analysis. Targeting the rural community considers other extenuating circumstances experienced by rural residents that can impact yoga participation in rural areas. Interviews were used to gain insight into a holistic viewpoint with the rich data bringing clarity to an individual’s thought process (of intention) to incorporate yoga (behavior) in their daily life. Utilizing the Theory of Planned Behavior as the theoretical framework for developing interview questions allowed …

Factors Associated With Covid-19 Vaccine Hesitancy In South Central Appalachia, Florence M. Weierbach, Rebecca Adkins Fletcher, Ingrid E. Luffman, Cynthia Meyer, Janet M. Keener, Manik Ahuja, Hadii M. Mamudu

Journal of Appalachian Health

Introduction: The newly emergent COVID-19 virus reached pandemic levels in March 2020. By the middle of August 2020, there were over 1 million deaths attributed to COVID-19 in the U.S., with those in rural areas outpacing urban counterparts. Prior to emergency approval of the Pfizer, Moderna and Johnson & Johnson vaccine formulations, mitigation efforts addressing individual behavior were challenging. However, even with the entrance of these three new vaccines, herd immunity was not achieved in rural areas, as vaccine uptake remained low there. Although there has since been an abundance of COVID-19-related research addressing health literacy, vaccine hesitancy and overall …

In an attempt to estimate forage production and carrying capacity of wild ungulates in Tandoureh National Park of Iran, the Babanestan grassland was selected, as the typical habitat of about 200 Urial wild sheep. In order to estimate the carrying capacity of this habitat for foraging of Urial wild sheep, this habitat with an area of 132 hectares was classified as low flat (LF), high flat (HF), north aspect (NA), and south aspect (SA). Then, to estimate forage production, clipping method of comparative yield was used. In each land form, standing crop yield of five reference plots of 1-^{m2 …}

Recurrence Interval Estimates For The July 2022 Eastern Kentucky Floods, North Fork Of The Kentucky River, William C. Haneberg

Open File Reports--KGS

July 2022 flood recurrence interval calculations for three gages along the North Fork of the Kentucky River—Whitesburg, Hazard, and Jackson, Kentucky—based upon both empirical distributions and theoretical log-Pearson Type III distributions yield a range of results from 851 years for the Whitesburg gage near the headwaters of the North Fork to about 2 years for the Hazard gage to 94 years for the Jackson gage. While the log-Pearson Type III approach worked well for the Whitesburg and Hazard gages, it produced an unrealistically low estimate for the Jackson gage because the empirical and theoretical curves diverge significantly for large floods …

IGC Proceedings (1977-2023)

Knowledge of grazing land carrying capacity and grazing pressure in and around protected areas is very crucial to support decision making over sustainable grazing levels and developing grazing pressure reduction strategies. However, there was lack of studies conducted on livestock carrying capacity and grazing pressure in the connected and dynamic system over a wider landscape scale. Hence, this study was conducted to estimate the livestock stocking rates and carrying capacity of grazing lands in Bale Mountain National Park (BMNP) and adjacent districts grazing lands, southeast Ethiopia. Three categories of data: Field surveys, satellite imagery, and socioeconomic secondary data were used. …

Back To The Future: How Do We Get There From Here? Making Restoration Work, K. Swilling, E. Bisangwa, Pat D. Keyser

IGC Proceedings (1977-2023)

Extreme temperatures and long periods of drought observed with increasing frequency in the southeastern United States (U.S.) have demonstrated the need to develop more robust forage systems. Native warmseason grasses (NWSGs) are well adapted to fill this role, but their expanded use comes with several challenges, most notably, reliable establishment. The high cost of site preparation, high cost of seed, and slow initial growth of NWSG seedlings must be addressed to achieve increased adoption of NWSG in the eastern U.S. If these challenges are overcome, incorporating NWSG into grazing systems would benefit producers by filling the summer forage gap, mitigating …

Impact Of The Brachiaria Hybrids On Both Soil Health And Carbon Stock On Livestock Production, A. Silva, T. Madeira, D. Florian, E. A. Pizarro, R. N. Jauregui, G. Lobato, A. Santi, D. Fagundes, F. Pinheiro, A. Rieger, A. Cagliari

IGC Proceedings (1977-2023)

Pastures occupy 30% of Earth and 80% of the entire agricultural area of the planet. To ensure food to the world and contribute to the quality of the environment, pasture-based animal production systems will also have to undergo through a more intense evolution. The intensification of tropical grasslands is an important strategy of land utilization in developing countries, contributing to increase production and minimize environmental impact through the best management practices. In this sense, the use of Brachiaria hybrids represents an excellent option, since combining the best traits of different Brachiaria species, with higher nutritive value, forage, and seed yield. …
