Dissertations, Theses, and Capstone Projects

Ecoacoustic monitoring via machine learning enables scalable analysis but is often constrained by labeled data scarcity, particularly in remote regions like the Arctic. This thesis confronts low-resource ecoacoustic audio classification by developing and evaluating complementary machine learning methodologies. We introduce EDANSA, the first publicly available, expert- labeled Arctic dataset of its kind, curated via novel active learning, alongside a baseline CNN. We systematically evaluate transfer learning, showing general audio embeddings effectively bootstrap classifiers for challenging Arctic sounds, significantly outperforming direct label mapping. Optimizing label utility, we investigate standard data augmentation and introduce novel audio data valuation via Shapley values, revealing …

This study aimed to evaluate the rate of surgical intervention following collagenase treatment and identify whether specific risk factors increase the likelihood of future surgical correction. Methods: This retrospective cohort study utilized the TriNetX US Collaborative network to identify patients diagnosed with Dupuytren contracture between January 2007 and September 2024. Patients initially treated with collagenase injections were identified using relevant current procedural terminology codes. Procedure-specific current procedural terminology codes were then used to determine which patients underwent a subsequent fasciectomy or …

Non-Linear Heart Rate Variability: Investigating Cardiac Complexity Of Psychopathic Traits, Khaya A. Roach

Dissertations, Theses, and Capstone Projects

Psychopathy is a complex personality disorder characterized by distinct emotional and interpersonal deficits, and affects approximately 25% of the prison population and 4.5% of nonincarcerated populations. The manifestation of psychopathy can be understood through two distinct variants, each demonstrating unique etiological pathways and clinical presentations. Primary psychopathy is characterized by core interpersonal and affective deficits, including shallow emotions and manipulativeness, while demonstrating reduced autonomic responsivity and lower anxiety levels. Secondary psychopathy presents with higher levels of impulsivity, anxiety, and emotional dysregulation, showing stronger associations with various psychopathologies. Treatment outcomes also vary between the variants, with primary psychopaths typically showing poor …

Repurposing Atractylenolide Iii, A Natural Anti-Inflammatory Compound, For Alzheimer’S Disease, Angela M. Steele

Dissertations, Theses, and Capstone Projects

Alzheimer’s disease (AD) is a debilitating neurological condition ranked as the fifth leading cause of death in adults over the age of 65. Despite the severity, 98% of drugs have failed as treatments for AD. Current novel drug development approaches have been unable to produce a disease-modifying treatment as they often have a one-target approach, not accounting for the complex nature of the disease. One of the hallmarks of the disease, inflammation, may provide a better target for treatment because it interacts with multiple facets of the disease. Drug repurposing to identify compounds that mitigate inflammation in AD could provide …

Scripted For Surveillance: Parole Revocation Hearings And The Performance Of Procedure In New York, Kelsey G. Greeff

Dissertations, Theses, and Capstone Projects

This thesis examines parole revocation hearings in New York as complex performances that extend carceral control beyond prison walls. Drawing on a composite vignette from the Bronx parole court, it analyzes the interplay between procedural reform, constitutional due process, and neoliberal governance. Using a dramaturgical framework informed by Michel Foucault’s discourse analysis and Judith Butler’s theory of performativity, the study identifies four interrelated processes: the judge as director, who orchestrates hearings according to institutional priorities; normalization, where repetition embeds structural inequality as routine; type-marking, the classification of parolees into predefined roles through accumulated records and cues; and the extension of …

Uncovering Environmental Justice Disparities: Tree Canopy Inequality In Low-Income Marginalized Communities, Emmanuel Wallace

Tennessee State University Alumni Theses and Dissertations

Tree canopy inequality in low-income marginalized communities is a direct result of decades of environmental injustice within urban communities in the United States, specifically the Home Owner’s Loan Corporation. This phenomenon underscores the disproportionate distribution of tree cover, green spaces, and their myriad benefits in neighborhoods marked by poverty and social vulnerability. Rooted in a history of discriminatory urban planning practices and systemic disparities, tree canopy inequality has profound consequences on residents' health and well-being. It leads to urban heat island effects, reduced air quality, and additional socio-economic disparities. On average, urban communities of color have 33% less tree canopy …

Dietary Modulation Of Obesity-Specific Gut Microbial Signatures And Their Functional Roles, Anjula Swathi Sagam

Tennessee State University Alumni Theses and Dissertations

Obesity remains a major global health concern, contributing significantly to chronic diseases. While diet is a well-known driver of obesity, emerging evidence suggests the key role of gut microbiota in mediating diet-related metabolic outcomes. Numerous epidemiological and microbiome studies suggested diet-microbiome-obesity associations. However, consistent microbial markers and mechanistic insights remain limited. To address this gap, this study aimed to identify consistent microbial species associated with obesity and investigate how diet influences their growth and function. A review of over 200 publicly available 16S rRNA and shotgun metagenomic studies revealed consistent microbial patterns in obesity, including members of Firmicutes and Bacteroidetes. …

Development Of The Negative Attitudes Toward Nonbinary Individuals Scale, Jenna Sue Lehmann

Tennessee State University Alumni Theses and Dissertations

Research within the field of psychology examining the experiences of transgender individuals and prejudice toward transgender individuals has increased in recent history alongside the conscious awareness of transgender individuals within the United States. The research that has been conducted has primarily focused on transgender individuals broadly as a group on binary transgender individuals. As, such measures of prejudice toward these groups have been developed and validated. Although the study of nonbinary experiences and prejudice is developing, there has been no extant measure of prejudice toward nonbinary individuals specifically. A measure of prejudice toward this group is needed to (1) examine …

Exploring The Cooling Effects Of Urban Forests In Summer, Xiaoyue Li

Tennessee State University Alumni Theses and Dissertations

As a nature-based solution to combat urban heat islands, urban forests can provide cooling and other co-benefits. However, little is known about the cooling benefits of urban forests in parking lots and under different land covers, especially with field observations. To address this gap, we measured air temperature (AT) and relative humidity (RH) and calculated heat index (HI) in three urban settings in Nashville, TN, in summer 2024. The research sites included: 1) Two different parking lots: parking lots with and without trees; 2) Three different distances from trees within the parking lot with trees: under trees, near trees, and …

Dynamics And Controls Of Greenhouse Gas Emissions In Bioenergy Croplands, Lovish Kasrija

Tennessee State University Alumni Theses and Dissertations

Agriculture contributes considerably to global greenhouse gas (GHG) emissions, requiring sustainable methods for tackling climate change. This thesis includes two mega-analyses and one field experiment to investigate the impact of conservation tillage and soil amendments on crop productivity and greenhouse gas emissions. The first mega-analysis combined data from 30 meta-analyses to assess the impact of no-tillage (NT), reduced-tillage (RT), and combination NT+RT on crop yields and soil GHG emissions. NT decreased yields by 3.3% and increased N₂O emissions by 8.7%, but RT and NT+RT had no effect. The second mega-analysis found that both NT and RT considerably increased soil organic …

Effects Of Soil Profile Rebuilding Techniques On Soil Properties And Tree Growth, Diksha Tamang

Effects Of Straw Return On Crop Yield, Soil Organic Carbon And Greenhouse Gas Emissions, Maazeera Fatima

Tennessee State University Alumni Theses and Dissertations

Global crop residue production was substantial, at approximately 3758 × 106 mg annually. The practice of straw return, was found to enhance soil organic matter content, increase crop yield, and mitigate soil greenhouse gas emissions. However, individual studies showed inconsistent results. While meta-analyses synthesized multiple individual studies and provided overall effects of straw return, but their conclusions were varied. We evaluated meta-analyses on the effects of straw return on crop yield, soil organic carbon, and greenhouse gas emissions and proposed a grand mean response ratio to estimate an overall effect and the impacts of different properties. The result showed that …
