Educating Black Males In Black Lives Matter Movement Space, Kimberly L. Hollis

College of Graduate Studies: Theses & Dissertations

This inquiry has been inspired by the stories of Black boys’ educational experience within the public school system in the South. Theoretically drawing upon anti-Black racism (Alexander, 2010; Collins, 2000; Davis, 2003; Du Bois, 1903; Watkins, 2001; Woodson, 1993; Wynter, 2003) and  Black Intellectual Traditions (Bell, 1992: Crenshaw, 1988; Delgado, R., & Stefancic, J., 2001; Ladson-Billings, 2003; Linscott, 2017; Yosso, 2006), I expound on the concept of systemic racism in the United States as well as the challenges that hinder Black males from achieving academic excellence and thrusts them further to the margins. Methodologically, I employ counter-storytelling (e.g., Delgado, 2017; …

Subliminal Nature: Dialogues In Performance, Carlos A. Carvajal

College of Graduate Studies: Theses & Dissertations

I will discuss how my artwork sets for the development of various layers of experience within the same context and space, to stimulate the subconscious of the audience. This layering is a combination of stimuli of senses (the inclusion of sound and active participation) and the syntax of the dynamics of audience interaction. Sound and visuals create a performance to acknowledge and read, while also pertaining to participation by a sort of instruction for the viewer to partake in the work. These are all different layers of experience that happen simultaneously within a piece, setting up different possible outcomes from …

Effect Of Elemental Additions On The Microstructure, Macrostructure, And Mechanical Properties Of Gray Iron, August E. Rautmann

College of Graduate Studies: Theses & Dissertations

Gray iron is composed primarily of an iron matrix and flake graphite, with the higher percentage of volume taken up by the iron matrix. The iron matrix is the transformation product of austenite, and this prior austenite structure is understood to affect the final grain structure. Grain structure affects the properties of a metal, with a finer structure recognized as beneficial for most properties. Thus, the refinement of austenite structure has potential in improving the material properties of gray iron. This study aims to advance the limited knowledge about the control of austenite grain size via elemental additions. Building off …

The Effect Of Chamber Geometry On The Performance Of Oscillating Water Column, Timilehin O. Osunade

College of Graduate Studies: Theses & Dissertations

This thesis investigates the effect of internal chamber geometry on the performance of a piezoelectric oscillating water column (OWC) wave energy harvester. Four acrylic chamber configurations with internal top-surface angles of 0°, 30°, 45°, and 60° were tested under 32 controlled conditions combining synchronous (SYN) and asynchronous (ASC) forcing at input voltages of 4, 6, 8, and 10 V. A 35 mm piezoelectric disc mounted at the chamber roof served as the power take-off element and, subject to the RC-limit caveat disclosed in Section 3.2.1, as a first-order dynamic analogue of the chamber pressure for phase-based compressibility analysis. All test …

Academic Coaching Modality, Academic Self-Efficacy, Academic Success, And Executive Functioning Skills In Students With Attention Deficit Hyperactivity Disorder (Adhd), Tracey Y. Hurd

College of Graduate Studies: Theses & Dissertations

As the number of students with a diagnosis of ADHD rises, postsecondary institutions must determine support services, such as academic coaching, that can contribute to their academic success. This study sought to examine the use of academic coaching in students with ADHD to increase executive functioning skills, while determining if the modality of the sessions affects these skills and student academic success, taking into consideration the role of academic self-efficacy in these behaviors. The study also examined Academic Coaches' perceptions of how their coaching practice impacts student academic success, the survey findings, and the potential impact of those findings on …

I Am Because We Are: A Narrative Inquiry Of Waiver Teachers’ Sense Of Belonging In Title I High Schools, Bernard Young

College of Graduate Studies: Theses & Dissertations

This qualitative narrative inquiry examined how former waiver teachers in low-performing Title I high schools in Georgia experienced a sense of belonging within their school communities and how that sense of belonging influenced their engagement in professional learning and their perceived effectiveness in supporting student achievement. Grounded in the Belongingness Hypothesis and guided by narrative inquiry methodology, the study framed participants’ experiences through the Bildungsroman structure to explore their journeys of professional becoming. Data were collected using a life-story interview protocol that combined open-ended narrative invitations with responsive follow-up questioning and were analyzed through a multi-phase narrative inquiry process informed …

Feasibility Of Quantifying The Dosage Of Zycotherm In Its Modified Asphalt Binders, Susmita Acharjee

College of Graduate Studies: Theses & Dissertations

The quantification of low-percentage additives in asphalt binders is challenging due to their minimal concentration and the complex composition of the binder matrix. Zycotherm, a nano-organosilane anti-stripping additive, is typically used in very small dosages (0.05%–0.20%), making its detection and quantification particularly difficult. This study investigated the feasibility of estimating Zycotherm dosage in asphalt binders by examining chemical and rheological and moisture responses. Two asphalt binder grades, PG 64-22 and PG 76-22, were modified with Zycotherm at dosages of 0.05%, 0.10%, 0.15%, and 0.20% by weight of binder, along with corresponding base binders. Laboratory experiments were conducted using Fourier Transform …

Identification Of A Rural Black Community-Based Mental Health Intervention Via Cbpr, Kirsten Mengell

College of Graduate Studies: Theses & Dissertations

Poor mental health in the US has increased since 2011 (Mental Health America, 2022). Rural communities face disparities in mental health shortages (Andrilla et al., 2018). African Americans face additional barriers, including a historical underutilization of mental health and high mental health stigma. This is significant given the higher rates of mental distress and discrimination among rural African Americans compared to Whites (James et al., 2017), and a recent increase in suicide among Black Americans (Stone et al., 2023). Illustrating a need for options within rural Black communities that can overcome professional shortages and cultural barriers to improve mental health …

Disrupting Ableist And Heteronormative Narratives Through The Other-Abled Body In Octavia E. Butler's "The Evening And The Morning And The Night", Morayo Joy Akingbelue

College of Graduate Studies: Theses & Dissertations

Ableist discourse has historically positioned disabled people as ‘unfit,’ resulting in their marginalization within society. This marginalization is not only manifested in terms of their physical performance but sometimes in the way disability intersects with race, gender, and sexuality, reinforcing the construction of disabled individuals as ‘other.’ While prominent feminist and disability scholars have challenged deficit based narratives of disability, Rosemarie Garland-Thomson’s concept of the misfit, Sami Schalk’s Defamiliarization, John Swain and Sally French’s Affirmative Theory, and Moya Bailey and Izetta Autumn Mobley’s A Black Feminist Disability Framework, Black women’s speculative fiction, offers a critical intervention by defamiliarizing dominant narratives …

Evaluating Source Material And Seed Propagation Techniques For Spartina Alterniflora To Enhance Salt Marsh Restoration In Coastal Georgia, Maygan Palacios

College of Graduate Studies: Theses & Dissertations

Salt marshes provide critical ecosystem services, including carbon sequestration, flood attenuation, and habitat for diverse aquatic and terrestrial species. Despite their ecological importance, these habitats are increasingly threatened by anthropogenic activities and rising sea levels. To protect and restore salt marshes and their ecosystem services, restoration efforts using living shorelines (LS) have become more common. Along the Eastern and Gulf coasts of the United States, the native grass Spartina alterniflora is commonly used in LS installations for its key role in salt marsh food webs, resilience to abiotic stress, and ability to stabilize and build sediment. Previous studies have documented …

Factorial Design: A New Look Through Overlap Measures, Sarah W. Liebenow

College of Graduate Studies: Theses & Dissertations

Traditional factorial analysis often relies on ANOVA, which assumes normality and equal variances. This thesis presents a nonparametric approach for assessing main and interaction effects in a 2 × 2 factorial design using the overlap coefficient, estimated through kernel density methods. A bootstrap procedure is used to approximate its sampling distribution for hypothesis testing. Simulation studies compare the overlap-based test with the ANOVA F-test, permutation F-test, and the Kruskal–Wallis test under heteroskedasticity and non-normal conditions. Results show that the overlap measure is highly sensitive to differences in spread and shape, detecting effects that traditional methods frequently miss.

Vibrio In Oysters: Exploring The Impact Of Harvesting Practices, Samin Yasar

College of Graduate Studies: Theses & Dissertations

The rapid growth of oyster aquaculture in the Southeastern United States necessitates the validation of post-harvest processing strategies to mitigate the risk of Vibrio spp. infection. This study investigated the efficiency of three cooling methods - Direct Ice Burial, Indirect Ice Cooling, and Ambient Control, on the prevalence and abundance of V. cholerae, V. parahaemolyticus, and V. vulnificus in cultured oysters (Crassostrea virginica) harvested in Georgia. Additionally, the study examined the safety of two different re-submersion periods for oyster safety.

Internal temperature profiles confirmed that while Direct Ice Burial achieved the most rapid cooling (< 10° C in 7.3 ± 1.2 min), the Indirect Ice Cooling protocol successfully reached the safety threshold in 73.7 ± 17.2 min, well within the 2-hour regulatory window. Microbiological analysis (N = 270) revealed that V. …
