Environmental Awareness And Community Sentiments In A Superfund Site: A Study Of South Chattanooga, Mia Dial

Honors Theses

The concept of environmental injustice refers to the disproportionate exposure of marginalized communities to environmental hazards, often resulting from the placement of industrial sites, waste facilities, or other environmentally harmful infrastructure in areas with limited political and economic power. Alton Park, a historically underserved neighborhood in Chattanooga, Tennessee, faces elevated environmental risks due to its proximity to the South Chattanooga Lead Superfund Site and legacy industrial contamination. This study used semi-structured individual interviews to assess community awareness, perceptions, and behaviors related to environmental hazards in Alton Park. Residents generally reported some awareness of the Superfund site, though knowledge was often …

Resilience By Living With The Land And Community: A Case Study Of A Local Food Forest, Olivia Beck

Honors Theses

Imagine a public space where food, leisure, outdoor activity, and community engagement occur in one place, all in an urban forest ecosystem. For many, this is a hopeful vision of the future, and that is exactly what the idea of an urban food forest provides. In agroecology, a food forest or forest garden consists of planting diverse edible plants and mimicking the patterns of natural ecosystems. The intricate planning and design ensure the forest is self-sustaining, much like a natural forest, making it very resilient once established. However, they face many challenges and take time to grow and develop to …

Preliminary Vascular Plant Checklist Of The City Of Chattanooga, Matthew J. Scott

Honors Theses

The City of Chattanooga, Tennessee was designated as a National Park City in April 2025 by the National Park City Foundation. Yet, there has not been a comprehensive vascular flora compiled for the city, though there have been extensive collections and observations made of the plant biodiversity in the area from the late 1800s onward. The goal of this project was to examine both the existing herbarium collections and public observation records from iNaturalist to compile a preliminary vascular plant checklist for Chattanooga, and to include conservation and ecological data for the species currently documented to provide a holistic review …

Growing Change: A Gis Spatial Analysis To Plan Urban Gardens In Chattanooga, Carson A. Chalk

Honors Theses

Food insecurity and limited access to fresh nutritious food in Chattanooga is a prevalent issue, primarily among lower socioeconomic households, and can put strain on overall well-being. This study aimed to identify suitable vacant parcels in Chattanooga where urban gardens could be developed using a GIS-based spatial analysis. Spatial data involving vacant parcels, slope, zoning, and proximity to grocery stores was cross referenced with socioeconomic data focused on poverty rates, vehicle ownership, and mean household income to identify the most suitable sites in areas of greatest need. Sites identified as suitable through GIS were then visited to verify their suitability. …

A Meta-Analysis Of Endometrial Cancer Metabolites As Potential Non-Invasive Biomarkers, Makenna K. Johnson

Honors Theses

Endometrial Cancer (EC) is the most prevalent gynecological cancer in the United States and causes tens of thousands of deaths. Despite its massive negative impact in developed countries, there currently is no reliable screening tool used to diagnose women. Due to this urgent need for minimally invasive and precise techniques to diagnose this malignancy, the metabolomics field has been at the forefront of current research. An untargeted mass-spectrometry approach is used by many researchers to form an initial hypothesis as to which metabolites are key in identifying EC cases. However, there are sometimes inconsistencies between studies. A meta-analysis approach examines …

Glass Vault - A Novella, Christopher M. Young

Honors Theses

This book focuses on several themes, but the core topics I wanted to discuss were family, mental health, and grief. One of the initial premises I wanted to pursue was the creation of a perfect storm in which all enjoyment came at the cost of a painful reality. Amber is a woman who has gone through several devastating events, struggling to accept the reality she finds herself in. By virtue of the incredibly unlikely scenario of finding and falling in love with a rich man, she already has a difficult time believing that the things around her are real sometimes. …

Contrasting Roles Of Downed Wood And Leaf Litter In Structuring Aphaenogaster Ants And Other Forest-Floor Arthropod Communities, Danielle E. Dolan

Great Lakes Center Masters Theses

Forest floors are dynamic and spatially heterogenous landscapes characterized by differing amounts of light, temperature, and moisture. Bounded substrates, like downed wood and leaf litter, add further complexity to this landscape. Specifically, downed wood is noted for its ability to retain a higher moisture level than the surrounding environment, and as such can serve as an ideal microhabitat for desiccation intolerant organisms (e.g., salamanders and eusocial insects). Here, I attempt to disentangle the relationship between forest floor arthropods and microhabitat selection (i.e., downed wood vs leaf litter) on a northeastern forest floor. The ant, Aphaenogaster picea, was chosen as my …

Pediatric Postural Orthostatic Tachycardia Syndrome: An Integrative Review, Esther Maclean

Senior Honors Theses

Postural Orthostatic Tachycardia Syndrome, otherwise known as (POTS) is a neurological condition that affects the autonomic nervous system. POTS often presents in adolescent women. This review looks at research surrounding possible treatment modalities including pharmacological and non-pharmacological interventions. The goal of this review is to increase healthcare provider knowledge surrounding POTS and increase the speed and efficiency at which POTS is diagnosed and treated in adolescents. This will be done by surveying the current research for best treatment methods, common comorbidities, and reasoning for delayed diagnosis. Common symptoms seen in POTS include syncope and pre-syncope, dizziness, fatigue, and decreased cognitive …

Is God An Illusion? Comparing Parasocial Relationships And Relationships With God, Parker J. Gungor

Senior Honors Theses

This thesis seeks to distinguish the parasocial relationship (PSR) from a relationship with God. A PSR is a one-sided relationship with a parasocial figure (PSF) such as a celebrity that gives the illusion of reciprocity. Since neither God nor the PSF interact with people in the same manner as standard reciprocal relationships, several key psychological theories are examined to highlight the similarities and differences between the relationships. A research gap is identified regarding the reciprocity of a relationship with God, so a study is proposed to compare the perceived responsiveness between a PSF and God. In comparing the perceived responsiveness …

Benthic Faunal Recruitment To Hesco Units In Barnegat Bay, Nj, Luke C. Blanchard

Theses, Dissertations and Culminating Projects

Forked River in Barnegat Bay, New Jersey, has undergone multiple ecological restoration and coastal remediation efforts in recent years. Among these initiatives is the installation of HESCO units, large wire-mesh cages filled with rock and shell substrate, designed to reduce shoreline erosion while simultaneously providing structural foundation for oyster-reef development. This study evaluated benthic fish and decapod recruitment associated with these installations using smaller-scale oyster boxes as analogs for HESCO habitat. Ten oyster boxes, each consisting of wire-mesh containers filled with oyster shell substrate, were deployed adjacent to the HESCO units beginning in June 2025 and retrieved at monthly intervals …

Differential Salinity Tolerance And Compositional Shift In Zooplankton Communities From Coastal And Inland Wetlands, Marisa Contreras

Theses, Dissertations and Culminating Projects

Anthropogenic salinization from road salt application has degraded freshwater ecosystems across the United States, yet the tolerance of freshwater communities to elevated salinity may depend on their historical exposure. Coastal systems experience natural salt intrusion through tides and storm events, potentially fostering greater salinity tolerance amongst resident organisms, while inland systems lack this exposure history. To investigate, I studied the abiotic and biotic responses of zooplankton communities from four wetlands across a salinity gradient to assess tolerance to experimental salt exposure. Two inland freshwater wetlands are subject to anthropogenic salinization from road salt runoff, while two coastal wetlands experience natural …

Improving Genomic Prediction For Feed Efficiency Traits In Beef Cattle Using Microbiome As An Intermediate Omics, Egodage Bhagya Sewwandi Samarakoon

Department of Animal Science: Dissertations, Theses, and Student Research

Feed efficiency traits, including feed conversion ratio (FCR), average daily gain (ADG), and average daily dry matter intake (ADDMI), are economically important in beef cattle production. Emerging evidence suggests that host genetics influences feed efficiency traits through the microbiome. This study evaluates the integration of microbiome data as an intermediate layer in the Neural Network Mixed Model (NNMM), which hierarchically models genotype–microbiome–phenotype relationships as a unified regulatory network to improve genomic prediction accuracy. To reduce the computational burden of NNMM, microbiome features dimension were reduced using principal component analysis (PCA) and direct feature selection of top-ranked open reading frames (ORFs) …

Carcass Mass And Cooling Dynamics As Determinants Of Beef Color, Tenderness, And Dark-Cutting Risk, Grace C. Johnson

Department of Animal Science: Dissertations, Theses, and Student Research

Discoloration in beef has important implications to the beef industry. Dark-cutting (DC) beef remains one of the most economically significant color defects; however, industry prevalence has only marginally declined (≈ 0.1%) despite mitigation efforts. This lack of improvement largely stems from research focused on pre-harvest stress and glycogen depletion leading to dark, firm, and dry (DFD) beef. However, not all darkcutting beef originates from DFD phenotypes. Atypical dark-cutting (ATDC) phenotypes have recently been observed and do not exhibit the classic metabolic indicators of DFD. This trend coincides with steadily increasing carcass weights in the beef industry and raises the possibility …

From Prairie To Practice: Forensic Taphonomy, Ethics, And Regional Ecology In Southeastern Nebraska, Jessica F. L. Gammage

Department of Anthropology: Theses and Student Research

Forensic taphonomy examines the postmortem processes that affect human remains within specific environmental contexts and plays a critical role in medicolegal death investigation. Despite significant advances in decomposition research, experimental studies remain geographically and environmentally uneven, limiting the transferability of postmortem interval (PMI) estimation methods across regions. The Central Great Plains are underrepresented in forensic taphonomic research despite its distinct ecological and geomorphological characteristics.

This thesis evaluates southeastern Nebraska as a specific regional setting for forensic taphonomic research by integrating ecological, pedological, and geomorphological data with current forensic literature. Tallgrass prairie vegetation, loess-derived soils, seasonal moisture variability, and dynamic fluvial …

Understanding Roma Oppression In Europe Through Humantarian Forensic Analysis, Christal L. Quinn

Department of Anthropology: Theses and Student Research

This thesis examines the marginalization of Roma people in Europe, and how humanitarian forensic practices may help Roma communities in their quest for justice and recognition. The study draws exclusively on secondary information to examine the social, political, and legal issues affecting the Roma communities, who have endured centuries of institutional discrimination, marginalization, and violence. This thesis identifies ways in which systematic oppression continues to limit Roma communities’ access to education, housing, healthcare, and legal protection through a review of relevant literature and applicable theoretical frameworks. The study also examines the relevance of forensic science, particularly its humanitarian applications, in …

Rehumanizing Anatomized Individuals: Using Osteobiographies As A Step Towards Reparative Justice, Lillie C. Turpin

Department of Anthropology: Theses and Student Research

In 1985, India banned the export of human remains. This ended the major trade route for primarily US and European anatomical supply companies. Until this point, companies like Carolina Biological Supply exploited and erased vulnerable people's identities, molding them into anonymous anatomical specimens. This study investigates the life and postmortem history of twenty-five individuals, previously used as anatomical specimens, housed at the University of Nebraska–Lincoln. Using an osteobiographical approach, this research reconstructs aspects of these individuals' lived experiences and examines how anatomical preparation practices reflect structural violence and apathy.

Skeletal analysis of twenty-five individuals revealed a range of biological profiles, …

Department of Anthropology: Theses and Student Research

This study explores the development and validation of an automated, deep learning system designed to differentiate human from large mammal long bone fragments using micro-CT imagery. A comprehensive dataset of cross-sectional µCT images was assembled from human and animal skeletal material processed at the DPAA, Nebraska. A convolutional neural network (CNN) based on a ResNet-18 architecture, utilizing transfer learning from ImageNet weights, was trained to classify µCT images as human or animal. The model achieved a mean classification accuracy of 89.85% (± 8.27%) across five sample-level cross-validation folds, with a sensitivity of 96.21% and a 95% bootstrap confidence interval of …

Roads To Antiochia Ad Cragum: Pedestrian Survey And A Least Cost Path Model Of Roman Roads In The Vicinity Of Antiochia Ad Cragum, Southern Türkiye, Alexander W. Pastor

Department of Anthropology: Theses and Student Research

Antiochia ad Cragum, a Roman site located in modern southern Türkiye, has been intensively investigated through archaeological study. However, the surrounding landscape has received less attention. This thesis addresses this gap by examining how this past settlement might have been accessed, which is an important step in gaining a better understanding of how people and resources traveled overland and how infrastructure was made to accommodate this travel. Pedestrian survey was conducted along posited western and eastern segments of a Roman-era road, finding remains consistent with but not definitively establishing this interpretation. In addition, Geographic Information Systems (GIS) was used to …

Bugs, Birds, Blue: Queer Ecologies Of Embodiment, Kinship, And Survival, Celeste B. Newcomb

Theses and Dissertations

bugs, birds, blue is a multi-channel audiovisual installation that examines queer ecology as a framework for understanding transgender embodiment, kinship, and survival amid environmental crisis and ongoing political attacks on trans life (Mortimer-Sandilands and Erickson). Through sculpture, projection, sound, reflective surfaces, and biological imagery, the installation places human bodily matter alongside microbial and aquatic life forms to challenge narratives that frame trans existence as unnatural, recent, or isolated. Instead, the work proposes transness as relational, adaptive, and deeply entangled with broader ecological systems. The installation is composed of two interconnected environments. On one side of the space, three aquariums rest …

Synthetic Explorations Towards Phenyl Benzazepine-Inspired Scaffolds And Synthesis Of Minor Cannabinoid Derivatives, Vishwashiv Kumar Emogaje

Theses and Dissertations

D1R is a compelling therapeutic target for correcting dopaminergic imbalances. However, existing ligands exhibit suboptimal pharmacokinetic properties. As such, we synthetically explored untouched structural modifications to the phenyl benzazepine scaffold. Cannabinoid-based molecules also display potential to treat neurological maladies and cancer. We synthesized Cannabichromene derivatives and uncovered enhanced anticancer activities.

Surface Gestures: Contemporary Sculpture, Material, And The Possibilities Of Finish, June Kitahara

Theses and Dissertations

Through the work of Tiona Nekkia McClodden, Patty Chang, and Jes Fan, alongside performance, cinema, cultural figures, and twentieth-century sculpture, the thesis argues that the surface of contemporary works reveals the inextricability of aesthetics from technologies of gendered racialization, sexuality, and sensation.

The I Need More Time Machine, Suzanne L. Schulz

Theses and Dissertations

The I Need More Time Machine imagines alternatives to gendered overwork and exhaustion. Incorporating animation and the interviews of twelve NYC-based female and nonbinary artists who are caretakers and full-time workers, the film dwells in spaces of fatigue and repetition — from the vantage point of commuting — then draws on forgotten feminist and utopian housing blueprints to create science fiction-inspired, fantasy-imbued sites for gendered flourishing. The animated fantasy segments imagine elastic time, deep rest, experiments in collaboration, and liberating feminist spatial possibilities

Genetic Screen For Regulators Of Pol4, A Dna Repair Polymerase In Saccharomyces Cerevisiae, Pasang Dolma Sherpa

Theses and Dissertations

In Saccharomyces cerevisiae, DNA polymerase 4 (POL4) is the beta repair polymerase, the product of the POL4 gene, and is involved in base excision repair (BER) and microhomology-mediated end joining (MMEJ). Despite its involvement in these repair pathways and its conservation across eukaryotes, deletion of POL4 shows no detectable phenotype under standard laboratory conditions. I hypothesized that unknown genes act as backup systems, providing redundant activities that allow pol4Δ cells to survive. To test this, a genetic screen for mutants showing synthetic lethality with pol4Δ was implemented. I constructed a strain lacking the POL4 gene and carrying …

Lemonade Everything Was So Infinite, Lauren Cline

Theses and Dissertations

In “Lemonade Everything Was So Infinite,” artist Lauren Cline uses her process-based approach to painting as a metaphor for the relationship between mundanity and eternity. Utilizing various frameworks, including the autobiographical writings of Hélène Cixous and the theology of Simone Weil, as well as examples from her own artworks,  the artist suggests that there is a universal human need for the dissipation of the singular, isolated self, and explores various ways that this can be achieved.
