Cultural Diagnosis And The Monsters Of Victorian England, Victoria Elizabeth Kuykendall

Theses and Dissertations

This dissertation examines the representation of invisible disability and neurodivergence in nineteenth-century British literature, arguing that literary texts both reflect and shape cultural understandings of disability. While much scholarship has focused on visible or physical impairments in Victorian fiction, comparatively little attention has been given to characters whose behaviors, emotions, or identities align with what today might be described as neurodivergence.

Drawing on Disability Studies, Mad Studies, and cultural theory, I propose the concept of cultural Diagnosis as a framework for analyzing how fictional characters become “Diagnosable” within both their historical and contemporary cultural contexts. Through close readings of Arthur …

Anthropomorphism In Language And Thought: The Effect Of Agentive Linguistic Framing On Readers’ Perceptions Of Ai Animacy, Dawson Petersen

Theses and Dissertations

Over the past decade, deep learning AI systems have gone from academic obscurity to near cultural centrality in the developed world. As these technologies become increasingly integrated into daily life, there is growing cause for concern about AI anthropomorphism—i.e., the perception of AIs as more human than they really are. Despite the potential risks, AI developers continue to market their technologies using agentive language that seems to be designed to encourage anthropomorphism. The current dissertation utilizes behavioral and eye-tracking methods to examine the relationship between agentive linguistic framing and AI anthropomorphism in both controlled judgments and automatic inferences. The results …

Adipokines Mediate Fat-To-Ovary Communication To Regulate Oogenesis, Adipocyte Size, And Lipid Storage In Drosophila Melanogaster, Chad Herbert Simmons

Theses and Dissertations

Humans have complex signaling pathways that allow them to store and expend energy based on nutritional quality and availability. Inter-organ signaling is used to communicate nutrient availability between organs based on nutritional needs and the rate of cellular division. Our main overarching question is to investigate how fat-derived signals affect adipocyte morphology and the maintenance of stem cells in the ovary. While signaling pathways, like insulin and mTOR, and some adipokines that are involved in inter-organ nutrient sensing have been identified, the exact nutrient reliant mechanisms of stem cell maintenance are not completely understood. Using Drosophila melanogaster as a model, …

Strategies For Developing Mathematical Identities In Middle School Students, Margaret M. Stevens

Theses and Dissertations

This concurrent mixed-methods action research study investigated the impact of mathematical discourse intervention on seventh-grade students’ mathematical identities and understanding. Twenty students participated in a four-week intervention implementing Smith and Stein’s (2018) five practices plus one framework.

Quantitative results showed curriculum-based assessments improved significantly (p < .001, d = 1.64). State mathematics assessment revealed minimal change in mean scores. The Mathematical Identity Questionnaire revealed positive shifts across all five constructs, with largest gains in Mathematical Initiative (+0.40) and Problem-Solving Persistence (+0.30). Qualitative analysis using Bingham’s (2023) five-phase process revealed three themes: Mathematical Voice Development, Identity Transformation Through Competence Building, and Communal Validation. Social Cognitive Theory and Culturally Relevant Pedagogy integration showed how discourse interventions addressed both individual self-efficacy and systemic inequities. Findings suggest intensive discourse intervention can initiate positive changes in mathematical identity and understanding for struggling students. Implications include restructuring mathematics instruction to prioritize student discourse and voice, creating more equitable learning environments.

Investigation Of Metals And Incidental Nanomaterials In Wildland-Urban Interface Fire Ashes And Their Impacts On Marine Phytoplankton, Talal Abdullah Alshehri

Theses and Dissertations

Wildfires are natural processes that have played a vital role in ecosystems for millions of years. However, with increasing anthropogenic activities and climate change, wildfires' frequency and intensity have increased. A wildfire is an uncontrolled fire that burns forests, grasses, and savannas. In addition to vegetation combustible materials, wildfire burn structure items such as homes, stores, and storage sheds in areas where the transition zone between urban and wildland is defined as the wildland-urban interface (WUI). Moreover, wildfires in WUI can burn vehicles, including automobiles, tractors, and boats on trails. Recently, there have been concerns regarding the metals, metalloids, and …

Thesis: Comparing Functional And Effective Brain Connectivity Metrics For Eeg, Diksha Srishyla

Theses and Dissertations

Background:Brain connectivity measures have been used to study communication between brain regions using electroencephalography (EEG). Functional and effective connectivity estimate the synchronization and the flow of information between regions, respectively. However, findings from studies using different measures to investigate similar connections do not converge. To guide the selection of functional and effective connectivity measures in future studies, we systematically compared a set of measures in the context of resting state EEG. We examined four functional connectivity metrics (coherence (Coh), the imaginary part of coherence (imCoh), the corrected imaginary part of phase lagged value (ciPLV), the debiased weighted phase-locking index (dwPLI)) …

Gut Microbiome Dynamics In Heart Failure And The Therapeutic Potential Of Nmeg-Cgrp, Kamryn Michael Gleason

Theses and Dissertations

Heart failure (HF) is increasingly recognized as a multisystem disease often linked to gut dysbiosis; however, its specific effects on gut microbial composition remain poorly understood. This study examined long-term changes in the gut microbiome in a murine HF model induced by transverse aortic constriction (TAC) and evaluated the effects of NMEG-CGRP. TAC mimics pressure overload-induced cardiac dysfunction, replicating key features of HF. CGRP, a neuropeptide with vasodilatory and cardioprotective effects, shows potential as a therapy for HF but is limited by rapid degradation. A stabilized analog, NMEG-CGRP, was used to assess its impact on cardiac and gastrointestinal health. Mice …

A Building Block Approach To Certification By Analysis Applied To A Ditching Analysis, Preliminary Studies, Sean Taylor

Theses and Dissertations

Extended Twin-Engine Operations (ETOPS) certification ensures safe trans-oceanic operation of transport category aircraft. A critical aspect of ETOPS certification is compliance with ditching regulations. The importance of ditching analysis has grown significantly and come under greater scrutiny because of the ‘Miracle on the Hudson’ incident. For transport category aircraft certified under 14 CFR 25 regulations, compliance with ditching requirements, rests on two major components. First, demonstrating acceptable aircraft dynamic behavior during the ditching event and second, ensuring the airframe can withstand the loads generated because of water impact.

Historically, original equipment manufacturers (OEMs) relied on comparisons to existing aircraft with …

Machine-Learning-Assisted Discovery Of Lattice Dynamics Signatures Of Sodium Superionic Conductors, Ogheneyoma Maxwell Aghoghovbia

Theses and Dissertations

Sodium superionic conductors are key to the development of all-solid-state sodium batteries. Discovery of new superionic conductors has traditionally relied on insights from material defect chemistry and the transition/hopping theory, while the role of lattice vibrations, i.e., phonons, remains underexplored. We identify key lattice dynamics signatures that govern ionic conductivity by analyzing the phonon mean squared displacement (MSD) of Na⁺ ions. By high-throughput screening of a dataset of 3903 Na-containing structures, we establish a strong positive correlation between phonon MSD and diffusion coefficients, providing a quantitative correlation between lattice dynamics and ion transport. To accelerate this discovery, we incorporate …

Spectral Modeling Of Electromagnetic Radiation From Power Converters, Regan A. Varner

Theses and Dissertations

Switching power converters are increasingly utilized in contemporary electronics. They are becoming more compact and operate at higher frequencies, which contributes to radiated electromagnetic interference (EMI). This EMI is important to quantify for electromagnetic compatibility of the converters with other nearby systems. In this thesis, analytical models have been developed for both ideal and non-ideal switching waveforms, employing piecewise functions to describe time-domain waveforms, with their corresponding frequency spectra derived and compared to empirical spectra. The results demonstrate that the comparisons with measured frequency data exhibit agreement with the analytical models up to approximately 25 MHz. Additionally, our analysis indicates …

Towards Robust Bmocz Schemes For Non-Coherent Wireless Communication, Anthony Joseph Perre

Theses and Dissertations

Non-coherent communication has emerged as a promising approach to address several challenges at the physical layer. A particular scheme called binary modulation on conjugate-reciprocal zeros (BMOCZ) uses the zeros (i.e, roots) of a polynomial to convey information bits. In this thesis, we strive to improve the reliability of BMOCZ in various scenarios. In particular, we utilize machine learning (ML) methods to determine the parameters for BMOCZ and improve upon the decoding performance. Moreover, we introduce a smooshed BMOCZ variant to combat typical impairments encountered within wireless communications, including timing offsets (TOs) for noncoherent orthogonal frequency division multiplexing (OFDM). Through numerical …

The Moderating Effects Of Community Involvement On The Association Between Witnessed Community Violence And Mental Health Outcomes Among Black Adolescents, Curtisha Tamara Shacklewood

Theses and Dissertations

Black youth and adolescents are at a disproportionately high risk for experiencing community violence exposure (CVE) and the potential influence it may have on psychological functioning. Research posits that Black youth who experience community violence are at a significantly higher risk of experiencing elevated internalizing symptoms (e.g., depression) and externalizing symptoms (e.g., delinquency). Previous research has utilized the ecological model to investigate interpersonal protective factors that potentially buffer the effects of CVE, including parental support and family characteristics. However, there is little research that explores community-level factors, such as community activities (e.g., youth activities and parental perception of collective efficacy) …

Improved Extraction And Detection Of Disinfection Byproducts, Impacts Of Wildland-Urban Interface Wildfires On Drinking Water, And Change In Disinfection Byproducts Over Time In Chlorinated Vs. Chloraminated Distribution Systems, Patrick Thomas Justen

Theses and Dissertations

Drinking water disinfection is critical to prevent the occurrence of waterborne pathogens in drinking water. However, disinfection causes the unintended formation of disinfection byproducts (DBPs) through the reaction of disinfectants (e.g., chlorine, chloramine) with natural organic matter (NOM), algal matter, or anthropogenic pollutants present in source waters. Exposure to DBPs is associated with increased bladder cancer, colorectal cancer, miscarriage, and birth defects. The U.S. EPA currently regulates eleven DBPs in drinking water—four trihalomethanes, five haloacetic acids, bromate, and chlorite. However, research shows that DBP related toxicity in drinking water is driven mainly by other, non-regulated DBPs, particularly iodinated DBPs and …
