Suburban Black Girl: Lived Experiences Of Black Girls And The Impact Of Safe Spaces Within Predominantly White Institutions, Kennedi A. Stevenson

Electronic Theses and Dissertations

As Black and Biracial girls navigate the landscape of suburban Predominantly White Institutions (PWIs), they encounter a unique convergence of institutional surveillance and interpersonal erasure. While existing literature often focuses on the “achievement gap” or urban school settings, this qualitative study investigates the lived experiences of Black girlhood within the sea of Whiteness that defines suburban education. Specifically, this research explores how a gendered sanctuary— BSU Salon Talk — serves as a site of resistance and a catalyst for wellbeing. Grounded in Black Feminist Thought Theory (BFTT) and Intersectionality, the study utilizes the theoretical frameworks of Patricia Hill Collins’ Domains …

Navigating Barriers: The Career Challenges Of Chinese Non-Stem Graduates In The U.S. Job Market, Dilin Li

Electronic Theses and Dissertations

This qualitative phenomenological study explored the career challenges faced by Chinese international graduates from non-STEM fields as they transition from U.S. higher education to the job market. While prior research has largely focused on STEM graduates who benefit from favorable visa policies and high labor demand, limited attention has been given to non-STEM students navigating structural, cultural, and social barriers to employment. Guided by the intellectual capital framework—which encompasses human, cultural, and social capital—this study examined how Chinese non-STEM graduates experience and respond to these barriers within the intersecting contexts of immigration policy, labor market expectations, and cultural adaptation.

Estimating Body Size And Biogeography In The Genus Alligator, Madelyn M. Turala

Electronic Theses and Dissertations

Several studies have examined correlations between total body length (TL) and skeletal measurements in the American alligator (Alligator mississippiensis), with some measurements serving as stronger predictors of TL than others. Femur length (FL) has been found to be tightly correlated with TL in A. mississippiensis, and this relationship has been used to estimate body size of extinct crocodilians. This thesis demonstrates that the humerus, radius, ulna, and tibia are also strongly correlated with TL and useful for body size estimation in A. mississippiensis, and thus, can be applied to related extinct crocodilians. Additionally, species distribution modeling …

Adsorption Of Pfas On Bridged Functionalized Organosilica Materials, Elisha Lawerh Kabutey

Electronic Theses and Dissertations

PFAS are hazardous contaminants that have a devastating impact on human health and the environment. Their hazardous nature has led to the development of various adsorption methods for removing these contaminants from water sources. In this study, functionalized organosilica materials were synthesized from bis[3-(trimethoxysilyl)propyl] amine using the sol-gel method. The surface amino groups of the organosilica were converted into amine hydrochloride groups. Their adsorption properties were evaluated using salts of perfluorooctanoic acid, perfluorooctanesulfonic acid, and perfluorobutanesulfonic acid. Results showed excellent adsorption capacity of the materials. Adsorption of PFAS leads to particle agglomeration and flotation of the spent material. A column …

Atmospheric Remote Sensing Using X-Band Radar In The Marine Atmospheric Surface Layer, Daniel P. Greenway

Electronic Theses and Dissertations

Atmospheric remote sensors have always offered promising technological advancements for measuring atmospheric properties over large spatial areas at high spatiotemporal resolution – a feat not currently possible with present atmospheric measurement technologies. However, remote sensors do not measure these atmospheric properties directly; they rely on robust calibrations or conversions, complex mathematical inversion methods, and/or machine learning to retrieve these properties. These inverse methods rely on the selection of an objective function, a machine learning technique, and an accurate parameterization for atmospheric property estimation. By leveraging inverse methods to improve the characterization of properties measured by remote sensors, this work enables …

Stability Of Paraffin-Insulated Nitrogen-Doped Carbon Fiber Ultramicroelectrodes, Maxwell H. Kwakwah

Electronic Theses and Dissertations

Nitrogen-doped carbon materials can facilitate the reduction oxygen-oxygen bonds, a key step in electroreduction of both O₂ (an important reaction in energy applications) and H₂O₂ (an important reaction in sensing and biosensing). Our lab previously demonstrated that thermal decomposition of urea in the presence of carbon fiber (CF) results in an N-doped carbon material that exhibits good electrocatalytic properties for H₂O₂ reduction. However, previous methods of insulating single N-doped CF via laser heating of borosilicate capillaries and epoxy to prepare ultramicroelectrodes (UMEs) seemed to adversely affect surface nitrogen contents and electrocatalytic properties. More recent work that utilized paraffin to …

A Revised Quantifier Variance And Its Implications On Vagueness, Isaac Alexander Huling

Electronic Theses and Dissertations

This paper argues that the Special Composition Question has no substantive answer, not because compositional talk is empty but because the physical structure it tracks does not have the form that would privilege a unique answer. The argument accepts Sider’s methodological premise that the world must provide structure beyond description if ontological vocabulary is to mean anything, and deploys that apparatus against his specific application of it to composition. Constraint processes among a system’s parts – the forces and interactions that hold rigid bodies together, maintain organisms, bind solar systems – satisfy every condition Lewis required of reference magnets. They …

Murdoch's Metaphorical And Mystical Moral Metaphysics, William Jade Langley

Electronic Theses and Dissertations

In this project, I explain the mysticism found in Iris Murdoch’s The Sovereignty of Good, emphasizing what the illustrative thought experiments and metaphors are meant to explain. To do this, I introduce her understanding of G. E Moore’s moral realism and compare this with how Bertrand Russell understands mystical intuition and revelation. Then, to understand how we can still do moral philosophy when morality is fundamentally mystical, I compare Murdoch’s usage of metaphor with that of Victoria Welby, who also takes metaphorical understanding to be crucial to our understanding of the world. Though Welby goes further than Murdoch in saying …

Educational Placemaking: The Radical Power Of Play, Hillary René Spencer

Electronic Theses and Dissertations

Too often, play is dismissed as a simple childhood pastime, but what if it were understood as a radical tool for transformation? This research examines how play-based learning (PBL) interventions can serve as a framework for systemic change. Grounded in Edward Soja’s theory of spatial justice, which holds that socially valued resources and opportunities are unevenly distributed across geographic spaces (Soja, 2010), the study investigates how public spaces can serve as culturally reflective sites of learning and, when co-created with children and their communities, help address historical structural inequities. This research establishes educational placemaking as a framework for understanding play-based, …

Kairosformer: Hybrid Transformer For Time Series Forecasting, Koichi Nishida

Electronic Theses and Dissertations

Long-term time-series forecasting is a fundamental problem in real-world applications such as financial modeling and weather forecasting. While Transformer-based architectures have shown strong performance in sequence modeling like natural language processing and computer vision, their direct application to time-series forecasting faces challenges including quadratic computational complexity and capturing inherent temporal dependencies. Recent works such as Informer and Autoformer address these limitations through sparse attention mechanisms and series decomposition, but introduce trade-offs between predictive accuracy and computational efficiency.

In this thesis, we propose Kairosformer, a Transformer-based architecture for long-horizon time-series forecasting that integrates probabilistic attention with series-wise temporal aggregation. By combining …

A Generalization Of Plane Partitions And Approximations Of The Resulting Function, Annette Jeanine Shinn

Electronic Theses and Dissertations

This dissertation is a generalization of two results which involve finding approximations of partition functions. The first is by Ayla Gafni in 2016, who found an approximation for the number of ways to partition a number n into k-th powers. The second is by E. M. Wright in 1931, who found an approximation for plane partitions. We look at a generalized partition function pk1,k2(n) that includes both cases and find an approximation for pk1,k2(n).

Developing A Noticing Skill Of Learners Of Jfl Through Writing With Chatgpt, Anna Suzuki

Acquiring an additional language, especially whose linguistic systems differ from a learner’s first language, such as English and Japanese, is quite challenging. However, the improvement of technology such as Artificial Intelligence (AI) has some potential in supporting language learning.

This study investigated how ChatGPT can assist learners of Japanese whose first language is English in writing Japanese narrative of a 4-panel story and what learners notice comparing their Japanese writing with ChatGPT’s production. This study followed three steps: writing, an online survey, and a one-on-one interview. Four undergraduate students who were taking either a 200-, 300- or 400-level Japanese course …

Three Implications For Leibniz’S Principle Of Sufficient Reason, Josiah Omiecinski

Electronic Theses and Dissertations

The Principle of Sufficient Reason (PSR) states that for everything that is the case, there is a reason for it being the case. The PSR has been a widely used principle in philosophy dating back to Parmenides (~500 BCE). While many philosophers are commonly associated with the PSR, none are as strongly associated with it than Gottfried Wilhelm Leibniz. This paper derives three surprising implications for Leibniz’s PSR from Leibniz’s claim that God, an unlimited mind, does not engage in reasoning while limited minds, like humans, do engage in reasoning. The implications are: A distinction between the PSR qua a …

Hereditary Transmission Of Drumming Among The Anlo-Ewe: The Case Of Agbodo/Amuzu Family Of Hatsukorfe, Denu, Volta Region, Ghana, Ernest Elikplim Kwabla Adonoo

Electronic Theses and Dissertations

This study examines the hereditary transmission of drumming among the Anlo-Ewe of southeastern Ghana, focusing on the Agbodo/Amuzu family of Hatsuk?ƒe in the Volta Region. Situated within ethnomusicological discourse on traditional Anlo-Ewe musical practices and the specialized roles of the researched family, who are drummers of the exclusive Ye?e religious tradition, this research argues that drumming in this context is not merely a musical activity but a complex system of communication, identity, ritual authority, and cultural continuity. The study fills and addresses a significant gap in existing scholarship on the Anlo-Ewe music, which has largely emphasized community dance-drumming and institutional …

The Application Of Natural Language Processing Towards Auditing Of Unstructured Data: A Design Science Approach, Dennis K. Amoatey

Electronic Theses and Dissertations

Financial auditors must manually review large volumes of unstructured text that may include contracts, internal policies, footnotes, and journal entry descriptions. This time-intensive process introduces risk of human error and inconsistency. Despite advances in automation, no systematic approach exists for applying Natural Language Processing (NLP) to this problem at scale. Using a design science approach, this study develops a framework that demonstrates how NLP techniques can be incorporated across key phases in the audit process, including planning, internal controls evaluation, evidence gathering, and reporting. Initial evaluation through expert feedback had a mix of responses. While some argued difficulty with data …

Stochastic Universal Differential Equations For Epidemiological Modeling: Uncertainty Quantification In Disease Transmission Dynamics, Alice Menaya Armah-Bonney

Electronic Theses and Dissertations

Epidemic forecasting requires not only predictions of expected case counts, but also quantification of uncertainty, although existing surrogate modeling frameworks for agent-based models remain fundamentally deterministic. In this thesis a Stochastic Universal Differential Equation framework is presented that extends the deterministic Universal Differential Equation approach by incorporating a learnable stochastic diffusion term, enabling calibrated probabilistic forecasts while preserving the mechanistic interpretability and computational efficiency of the deterministic baseline. In doing so, a two-phase training algorithm is introduced to ensure stable convergence and the framework is validated against the ensemble output from ExaEpi, an exascale agent-based model of a COVID-19 outbreak …

Attendance Matters: Incentive Programs And Chronic Absenteeism In Elementary Schools, Aubryn Street

Electronic Theses and Dissertations

Chronic absenteeism is a common challenge in elementary education. Schools often use attendance incentive programs, such as rewards or recognition, to encourage students to attend regularly. However, it is not always clear whether these programs actually improve attendance. This study examined whether attendance incentive programs are effective and how school staff view and use these programs.

This mixed-methods study used both school attendance data and interviews with school personnel. Attendance data from two school years showed that schools with incentive programs did not have lower absenteeism rates than schools without them. However, attendance improved overall from one year to the …

On The Algebraicity Of The Tic-Tac-Toe Matroid And Homogeneous Mixed Bowtie Systems, Benjamin R. Allen

Electronic Theses and Dissertations

This thesis is presented in two parts. First, we explore whether the class of algebraic matroids is closed under duality, a decades-old open question. We consider the Tic-Tac-Toe matroid as a potential candidate to answer the open question. The Tic-Tac-Toe matroid is known to satisfy many of the necessary conditions for a matroid to be algebraic and has a non-algebraic dual.  Second, we focus on decompositions of the complete mixed graph into mixed bowties. A complete mixed graph has between every pair of vertices an undirected edge and antiparallel arcs. A mixed bowtie is a graph consisting of two 3-cycles …
