Evaluating The Effects Of Urbanization On Meiofauna Biodiversity In Chattanooga’S Lentic Ecosystems Through Gis Applications, Keyle M. Bryant

Honors Theses

Urbanization is a leading driver of biodiversity loss in freshwater ecosystems, yet its effects on meiofauna—microscopic invertebrates that serve as key bioindicators of ecosystem health—remain poorly understood in lentic environments. This study evaluated the effects of urbanization on meiofaunal biodiversity in ten lentic waterbodies across Hamilton County, Chattanooga, Tennessee, by integrating environmental DNA (eDNA) metabarcoding, in-situ abiotic measurements, and Geographic Information Systems (GIS)-based land use analysis. Water samples were collected between January and April 2023 and processed using 18S rRNA amplicon sequencing to assess biodiversity as richness (amplicon sequence variants or ASVs, phylogenetic diversity or PD, and community composition). Land …

How Do Community Gardens Contribute To A Thriving National Park City: A Case Study Of Chattanooga, Tennessee, Ansley B. Barry

Honors Theses

On April 3, 2025, Chattanooga, Tennessee became the first National Park City (NPC) in North America. With a long, industrial history, Chattanooga has made quite the pivot from being widely renowned for its low air quality and particulate pollution to being recognized as the Best Outdoor City in the US by Outdoor magazine. The goals emphasized by the National Park City campaign are creating a city-wide common interest of community-led sustainability efforts. While the initiative highlights many important initiatives to make the city more sustainable and resilient, community gardens are noticeably left out of the conversation. This paper argues that …

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 …

Unraveling The Modernist Grid: An Exploration Of Femininity And Containment In Design History, Riley Hayes

Honors Theses

This paper examines the Swiss grid as both a foundational tool of modernist graphic design and a cultural system embedded with ideological assumptions about order, neutrality, and authority. While the Swiss design tradition is widely celebrated for its clarity, rationality, and universality, this study argues that such principles are not neutral but historically situated, shaping how postwar Western visual culture organizes information, bodies, and value systems. Focusing on the circulation of Swiss design principles through editorial and advertising media, the paper situates the grid as a structuring logic that extends beyond layout into the framing of identity and gender. This …

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 …

The 5i’S Framework Of Creative Self-Leadership, Maggie Cubbler

Creativity and Change Leadership Graduate Student Master's Projects

The purpose of this Master of Science in Creativity and Change Leadership project is to establish a framework for Creative Self-Leadership (CSL) development. Viewed through a gendered lens, the framework addresses how women's intrapersonal processes—the 5I's of introspection, interoception, intuition, imagination, and intrinsic motivation—are often compromised by sustained environmental and systemic pressure, and proposes practices designed to restore and strengthen these internal guides.

By recalibrating these intrapersonal processes toward accurate self-knowledge, CSL employs the science of creativity to lead women in their own quest for change, agency, and resilience while remaining cognizant of the dynamic between her and her environment.

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) …

The Detection Of Morbidity Using A Remote Sensing Ear Tag On Newly Received Steers And Feedlot Performance And The Effects Of Feeding Experior And Optaflexx On Carcass Characteristics And Meat Tenderness In Beef Steers, Lauryn O. Smidt

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

Two experiments were conducted to evaluate the effects of remote sensing health technology and growth-promoting feed additives on feedlot cattle performance, health outcomes, and carcass characteristics. In the first study, 638 crossbred steers (initial BW = 270 kg; SD = 18.6 kg) were used in a randomized block design to assess the effectiveness of a remote sensing ear tag (RST; HerdDogg, Seward, Nebraska) versus conventional pen-rider observation (PR) for detecting morbidity during a 35-d receiving period and subsequent 180-d finishing period. No differences were detected between PR and TAG for ending BW, average daily gain (ADG), dry matter intake (DMI), …

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 …

Non-Destructive Automated Classification Of Human And Large Mammal Long Bone Fragments: A Deep Learning Approach Using Micro-Ct Histomorphology And Grad-Cam Interpretation, Kathleen Marie Kelley

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 …

Ephemeral System, Shibo Chan

“Before Your Honour?”: Divine Morality And Women Reclaiming Power In Ben Jonson’S Volpone And William Shakespeare’S Measure For Measure, Delilah G. Fleming

Theses and Dissertations

This thesis explores how the female protagonists in Shakespeare’s Measure for Measure and Jonson’s Volpone navigate and combat corrupting patriarchal forces through moral religious speech. In both plays, the male characters have allowed false gods and hypocrisy to dictate and justify their corrupt behavior. By engaging with the historical significance of early modern female rhetoric this thesis examines Jonson’s Celia and Shakespeare’s Isabella, and how they operate in the interest of godly virtue rather than blind obedience to patriarchal figure heads.  Volpone’s Celia is a character largely neglected in the canon, and whose speech emphasizes the relationship between female agency …

We assessed biodiversity changes for a proposed oyster reef restoration site to help guide management, future assessment, and deepen understanding of how oyster reefs function and their ecosystems dynamics.

Initial Type Craft, Micah Angelus

Theses and Dissertations

What kinds of objects can still think when the self-contained aesthetic object can no longer be taken for granted? The historical ruptures that have placed painting under crisis have also brought into view the fallacy of artistic autonomy, raising questions about how value, contemplation, and meaning persist under conditions of deconstruction.

The Monsters We Make: Confronting Repression And Failure In Mary Shelley’S Frankenstein, Ben Wilenski

Theses and Dissertations

This thesis builds upon psychoanalysis and Shelley’s biographical accounts to claim that, rather than creating fear through physical monstrosity, Frankenstein’s horror emerges from the return of repressed parental and social failures. While the novel never excuses its violence, it contextualizes the creature’s acts in ways that demand readers to confront complicity, neglect, and social shortcomings. The following section discusses general horror theory with a focus on notions of abjection and the synthesis of contrasting images and concepts. A baseline understanding of fear will be formed and referred to in each following segment. After establishing a basic understanding of horror vocabulary, …

Living Doll: Puppetry, Performance, And The Art Of Greer Lankton, Madison Lee

Theses and Dissertations

This thesis argues that puppetry is the animating logic of Greer Lankton's practice. Drawing on archival evidence—including letters, planners, and drawings—it recovers an engagement with puppetry spanning childhood through her final years, and applies puppet theory to argue that Lankton understood selfhood as something made, not given.

Wind In A Dry Glass, Khia Hong

Theses and Dissertations

Khia Hong’s paper unfolds in five sections, tracing the ontological and epistemological inquiries behind her sculptures. When the sculptures stepped down from the pedestal and entered the plane of lived reality, the question “What is sculpture?” expanded into “What is sculpture, the self, and the world?” Through reflections on the self, Hong details how these questions emerge and are addressed in her material encounters.

“One Object Yields Both Grief And Joy”: Death In Elizabeth Cary’S The Tragedy Of Mariam (1613), Valeria Suprunova

Theses and Dissertations

This thesis argues that the dialog between early ancient Roman and early modern English traditions of death and dying helps illuminate the complex relationship between tyranny and death in Elizabeth Cary’s The Tragedy of Mariam (1613) and that death is an inextricable and dynamic element of the text.

Beauty Over Perfection: The Idealization Of Drapery In Classical Greek Sculpture And The Stylistic Reinvention Of Roman “Copies”, Lauren M. Grover

Theses and Dissertations

This thesis explores Margarete Bieber’s claim that the drapery of Greek sculpture accurately reflects ancient garments. I introduce a method of tracing drapery to capture the garment pattern of sculpted drapery and argue that the drapery of Greek originals and Roman “copies” is an idealized representation of ancient dress.

Sentential Structures In Alexander Scriabin's Op. 8 Etudes, John Paul West

Theses and Dissertations

Historically, the sentence has proven to be one of the most versatile and pervasive forms in music, appearing since the mid-sixteenth century with occurrences too frequent to quantify. Sentential musical phrases emerged from music and poetry during the late-sixteenth and early-seventeenth centuries with the same short-short-long rhythmic impulse, originating from poetic and sing-song texts. Although the sentence is most often tied to the Classical period, it is not associated with any single era. Patterns of sentential phrases were already apparent and plentiful before the late eighteenth century, and composers used it as a device to expand musical form throughout the …

Notes On Rhythm, Maya Lee-Parritz

Theses and Dissertations

Line meets impulse, association meets sign. I weave the eye towards the smudge and sublime—a fractal lineage flowing through the brush, my body, space itself. I walk toward reality in serial successions, allowing what is fragmentary to move me, to cohere in shards, murky and strange inside of me. My body is a repository of images, of broken rhythms and dissonant ideologies. All of these flow and stutter onto the surface, dripping and blurring over each other. Through all of this, I always try to make something whole, perfect, and true.

Optional Freedom: The Idea Of Voluntary Slavery In Antebellum Law And Literature, Vinh T. Pham

Theses and Dissertations

This thesis elaborates “voluntary slavery” as a problem for thought for both proslavery legalists and literary writers in the antebellum period. It takes as its point of departure the passage of Southern laws throughout the 1850s that provided free Black persons the option to petition for self-enslavement to a master/mistress of their choice, and the safeguards within them that led a significant number of such petitions to be rejected. Given the political tensions of the 1850s, why would legal practitioners actively impede the option of self-enslavement? Implicit in these rejections is the possibility that self-enslavement was in some way a …

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 …

Fishing, Butchery And Smoking: Salmonids In Northeastern Iceland, Quinn Matthew Habedank

Theses and Dissertations

This paper explores the ethnoecology of Northern Iceland from 1880-1920 via the zooarchaeology of salmonid remains. Based on the identification of salmonid bones retrieved from Hofstaðir, the people living at the farm likely engaged in small-scale production of transportable fish products based on locally available wild resources.

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.

The Storyteller: Concealment, Memory, And The Architecture Of Exile, Dylan Hirsh

Theses and Dissertations

The Storyteller is an expressive documentary investigating the life of Francis Kalnay (1899–1992). A Jewish-Hungarian intellectual, Kalnay lived as a socialist, an X-2 Counter-espionage chief for the American Office of Strategic Services (OSS) during World War II, an architect in Mexico, and a celebrated children's book author. The film's central conflict lies in his hidden identities and exploring how, despite his position as a high-level spy, he failed to save his sister and mother from death at the hands of the Nazi-aligned Arrow Cross government. As a filmmaker investigating a lost part of my own Jewish-Hungarian heritage, I believe Kalnay …
