Understanding The Potential Biogeochemical Effects Of Alternative Restoration Materials: A Study Of Basalt And Other Materials, Cadie L. Barnes
Understanding The Potential Biogeochemical Effects Of Alternative Restoration Materials: A Study Of Basalt And Other Materials, Cadie L. Barnes
Graduate Studies Theses and Dissertations 2026
Concern over the effects of microplastics on estuarine ecosystems and public health has prompted many restoration practitioners to switch from plastic materials to more “natural” substrates. These natural (BESE-biopolymer, cement-jute structures) and non-plastic (basalt fiber) materials should not contain harmful substances; however, their chemical composition is unknown. Natural materials may degrade faster in subtropical environments and release nutrients into surrounding waters, which is concerning for eutrophic restoration areas. Basalt fiber bags, made from melted basalt rock spun into fibers, have not been evaluated for biogeochemical impacts within estuaries. To address this knowledge gap, two field experiments and two laboratory experiments …

Establishing And Testing Experiential Critical Theory (Ect), Dolores M. Batten Mrs.
Graduate Studies Theses and Dissertations 2026
There is a current gap in academia which has been largely overlooked in both pedagogy and assessment: the value of personal experience as key evidence of interpretation and meaning-making correlation. Aside from narrative writing, most current methods of literary analysis writing do not place a high value on personal experience beyond the inclusion of brief anecdotes. Yet experience is the major pathway by which an individual forms their worldview, which then informs the ways in which they interpret the world—and by extension, text. This dissertation both establishes and examines the use of Experiential Critical Theory (ECT) in pedagogical application for …
Reflection In Still Waters: Generative Ai's Production Of Language, Jonathan D. Hawks
Reflection In Still Waters: Generative Ai's Production Of Language, Jonathan D. Hawks
Graduate Studies Theses and Dissertations 2026
Language is a conceptual process of meaning-making as well as a social construction as defined by Saussure, Bakhtin, and Lacan. Large Language Models (LLMs) engage with neither process and instead present language as a finished and consumable product which undermines its fundamental aspects. The difference between representing language through probability and its structural components instead of its more inherent qualities is not a pointless distinction. This paper utilizes Narcissus as a central metaphor to show how people misread the outputs of LLMs as language which imparts to those reflected words meaning on par with our own conceptualizations of reality. People …
Watch Your Step, Mind The Crowd: Socially Compliant Navigation In Unstructured Environments, Jack Vice
Watch Your Step, Mind The Crowd: Socially Compliant Navigation In Unstructured Environments, Jack Vice
Graduate Studies Theses and Dissertations 2026
Autonomous mobile robots increasingly operate in complex real-world environments characterized by uneven terrain, dynamic obstacles, and human presence. This dissertation addresses the fundamental challenge of developing adaptive navigation strategies that enable robots to safely and effectively traverse unstructured outdoor environments including construction sites, agricultural fields, and disaster areas while maintaining social compliance around people. We advance this capability through five complementary contributions that collectively target dynamic, unstructured, human-occupied environments. First, we demonstrate evolutionary optimization of legged mobility for uneven terrain. Second, we propose using a spatiotemporal autoencoder to learn the temporal dynamics of moving people and objects. Third, we introduce …
Fgf19 As A Colorectal Cancer Serum Biomarker And Fgfr4 As A Mediator Of Anti-Her2 Resistance In Breast Cancer, Jordan Beardsley
Fgf19 As A Colorectal Cancer Serum Biomarker And Fgfr4 As A Mediator Of Anti-Her2 Resistance In Breast Cancer, Jordan Beardsley
Graduate Studies Theses and Dissertations 2026
The fibroblast growth factor 19 (FGF19)-fibroblast growth factor receptor 4 (FGFR4) signaling pathway regulates hepatic metabolism, bile acid (BA) synthesis, and hepatocyte proliferation. This signaling axis also is implicated in promoting tumor progression, therapeutic resistance, and metastasis in certain cancers.
In colorectal cancer (CRC) there is a critical need for non-invasive biomarkers for disease detection and monitoring. We identified FGF19 as a candidate CRC serum marker through meta-transcriptomics and found FGF19 to be expressed and secreted by CRC cell lines. Tumor-derived FGF19 was detectable in mouse serum at levels correlating with tumor volume in a subcutaneous xenograft model. RNA sequencing …
Investigating The Anti-Apoptotic Properties Of The N-Terminus Of The Chlamydia Trachomatis Effector Tarp, Kasey S. Jordan
Investigating The Anti-Apoptotic Properties Of The N-Terminus Of The Chlamydia Trachomatis Effector Tarp, Kasey S. Jordan
Graduate Studies Theses and Dissertations 2026
As the most prevalent bacterial STI in the United States and leading cause of infection-related blindness worldwide, the obligate intracellular bacteria, Chlamydia trachomatis (Ct), poses a significant threat to public health. As an obligate intracellular bacteria, invasion of the host cell is a crucial step in Chlamydia’s developmental cycle. To drive invasion, Ct injects prepackaged effectors into the host cell using a T3SS. An early Chlamydial effector, translocated actin recruiting phosphoprotein, or Tarp, interacts with host cell actin to promote invasion, mediated via Tarp’s C-terminal region. Although the function of Tarp’s C-terminus is well defined, the Tarp’s N-terminus …
Mathematical Modeling And Characterization Of A Variable Stiffness Ankle-Foot-Orthosis, David E.L. Richards
Mathematical Modeling And Characterization Of A Variable Stiffness Ankle-Foot-Orthosis, David E.L. Richards
Graduate Studies Theses and Dissertations 2026
Conventional ankle–foot orthoses (AFOs) typically employ static stiffness profiles that do not replicate the dynamic quasi-stiffness of the human ankle during gait. Variable stiffness mechanisms (VSMs) offer a promising alternative solution for gait pathologies, such as foot drop and post-stroke hemiparesis; however, their implementation is limited by the lack of accurate mathematical models capable of predicting force and stiffness characteristics. The objective of this thesis is to develop and validate comprehensive mathematical models describing the kinematics and kinetics of a novel variable stiffness ankle–foot orthosis (VS-AFO). This study derives governing equations to characterize how mechanical adjustments influence the force transmission …
Ambulatory Monitoring Of Biomarkers For Enhanced Recovery, Lucas Abrahamian, Gurman Dhami
Ambulatory Monitoring Of Biomarkers For Enhanced Recovery, Lucas Abrahamian, Gurman Dhami
Bioengineering Senior Theses
Oxidative stress, an imbalance of reactive oxygen species and antioxidants, serves as both a marker and progressor of several chronic and degenerative diseases. These conditions create a major global health burden, accounting for significant cost and deaths. The prevalence of oxidative stress–driven diseases highlights the need for improved strategies to detect the imbalance before irreversible damage occurs. However, despite its major role in disease progression, oxidative stress is typically assessed using static, invasive, or laboratory methods. These approaches are poorly suited for continuous monitoring and fail to serve high-risk groups, such as patients with a family history of disease or …

Development Of In Vitro Hydrogel Blood Clots, Xiomara Garcia, Jasmine Urbina, Sapna Wolf
Bioengineering Senior Theses
Deep Vein Thrombosis (DVT) affects up to almost one million individuals in the United States annually and can lead to life-threatening complications, such as a pulmonary embolism. DVT occurs when a thrombus composed of platelets and fibrin forms within deep veins, obstructing blood flow. Current treatments include anticoagulants, thrombolytics, inferior vena cava filters, and balloon catheter procedures. However, the development and testing of these medical devices heavily rely on animal blood models due to physiological similarities in coagulation, raising ethical concerns and limitations related to cost, scalability, and sustainability. This project proposes a synthetic, in vitro alternative using agarose and …

The Ocean Is Not A Machine: A Feminist Media Analysis Of Oceanographic Models, Simulations, And Futures, Clarissa Chevalier
The Ocean Is Not A Machine: A Feminist Media Analysis Of Oceanographic Models, Simulations, And Futures, Clarissa Chevalier
Study of Women, Gender, & Sexuality: Faculty Publications
This article examines how scientific and artistic representations and technologies shape ocean futures. Dominant Western oceanography frequently engages mechanistic metaphors that conceptualize the ocean as a machine, pump, or carbon sponge. This way of visualizing the ocean, guided by the logics of control and quantification, shapes contemporary remote sensing, modeling, and prediction technologies. Alternative approaches to oceanographic representation, including Indigenous, anticolonial, Black feminist, and artistic approaches, offer critical counterweights to destabilize the authority granted to mechanistic oceanographic representations. Ocean simulations and scale models are infrastructures through which ocean futures are rendered and presented in multidimensional space. Through a comparative media …
