Capable Rhetoric: Embodied Rhetorical Listening And Midwives' Arguments For The Maternal Body On Instagram, Aminta C. Quintero-Jackson

Graduate Thesis and Dissertation post-2024

When women find out they are pregnant, they encounter discourse about their bodies they may not have consciously considered before. Frequently, the information is based on ideologies that consider maternal bodies to be inherently problematic. The discourse in this information informs and shapes women’s choices about the role of medical oversight in their pregnancies and impacts the perceptions they have of themselves.

Midwives argue that mothers and their bodies are not inherently problematic but are powerful and capable of childbirth. They argue that medical oversight has been too aggressive in birth management, interrupting the natural process of birth and causing …

Bending Mechanics Of Bio-Mimetic Stiff Scale-Covered Plate, Pranta Rahman Sarkar

Graduate Thesis and Dissertation 2023-2024

Biomimetic scale-covered systems offer immense potential and applications, particularly in soft robotics, protective armors, wearable materials, and multifunctional aerospace structures. A typical system consists of stiff rectangular plate like scales embedded in a softer media and arranged periodically. Experimentally, these systems indicate pronounced nonlinear strain stiffening behavior even when the underlying substrate strains are small. However, capturing these behaviors using commercial finite element (FE) codes has proved difficult due to multiple sliding contacts between the scales after engagement. Therefore, accurate and reliable analytical models of architecture-property-relationships are needed for analysis and design. This thesis investigates the contact kinematics and mechanics …

Exploring The Physiology Of Clostridioides Difficile: Selenium-Dependent Catabolism Of Host-Derived Nutrients, Michael A. Johnstone

Graduate Thesis and Dissertation 2023-2024

Clostridioides difficile is a bacterial pathogen that causes pseudomembranous colitis and the majority of antibiotic-associated diarrheal cases. Broad-spectrum antibiotic usage disrupts the normal gut microbiota and thereby compromises colonization resistance, the main defense against C. difficile infection. Treatment options are limited to vancomycin, fidaxomicin, and the fecal microbiota transplant. Addressing the scarcity of these therapeutics, we documented two explorations in C. difficile drug discovery: (i) evaluation of antibacterial and toxin-suppressing activity of (+)-puupehenone and similar derivatives, and (ii) clarification of a discrepancy in the hypothesized mechanism of auranofin against C. difficile. A better understanding of how C. difficile colonizes …

Comparative Analysis Of Metric And Non-Metric Ancestry Estimation Methods Of Maya Individuals, Griffon G. Binkowski, Channing Cook

High Impact Practices Student Showcase Spring 2024

Ancestry estimation finds its place in many fields of anthropology, including biological anthropology, osteoarchaeology, and paleopathology. A biological profile creates a framework for identity; with ancestry, it can aid researchers in determining the population group an individual is most genetically affiliated with. The heritability of dental traits makes teeth useful in estimating affinity. Ancestry estimation statistical programs using dentition, however, were originally developed upon limited and well- preserved databases, so archaeological Indigenous individuals are often grouped incorrectly as East Asian due to shared genetic traits. By using RStudio for anthropological statistical analysis, we aim to test the preservation bias and …

Gait Entrainment & Energetics Of Young Adults To Discrete Mediolateral Perturbations, Lindsey D. Lee

Graduate Thesis and Dissertation post-2024

Entrainment is a natural phenomenon that occurs with synchronization to a rhythmic stimulus which can be auditory, visual, or mechanical. An everyday example is walking next to someone and synchronizing your steps. Previous studies have explored entrainment from auditory cues, such as a metronome, and mechanical cues, such as an exoskeleton applying a force at the ankle. These studies have found entrainment is more likely to occur if the stimulation frequency is close to the person’s natural locomotion frequency. Previously we found when discrete mediolateral perturbations were applied on a treadmill, participants increased their speed and retained this increased speed …

Quantifying Age And Growth Rates Of Gray Snapper (Lutjanus Griseus) In Mosquito Lagoon, Florida, Wei Chen

Graduate Thesis and Dissertation post-2024

Gray snapper (Lutjanus griseus) is a common reef fish inhabiting the western Atlantic Ocean. In estuaries of the Southeastern United States, such as Mosquito Lagoon, Florida, oyster reefs, seagrass, and mangrove shorelines are vital nurseries, also known as essential fish habitat (EFH), for juvenile fish. However, EFH in Mosquito Lagoon has declined from historic levels due to human activity. To mitigate these losses, oyster reef and living shoreline restoration projects have occurred to putatively increase the availability of EFH. For gray snapper in Mosquito Lagoon, past studies have assessed local habitat preferences and trophic structure, but the biotic …

The Influence Of Natural And Anthropogenic Drivers On Estuarine Food Webs At Various Spatio-Temporal Scales And Levels Of Complexity, Michelle Shaffer

Graduate Thesis and Dissertation post-2024

Global coastal ecosystems support human life by providing critical services like food, water purification, and coastal protection, yet these ecosystems are among the most threatened due to natural and human-driven disturbances. The long-term maintenance and restoration of these ecosystems is a complex challenge for resource managers due to the wide range of factors affecting these ecosystems ecological condition over long timespans. Most studies in marine ecology evaluate ecosystem change over relatively short temporal scales (ago), often resulting in shifting baseline syndrome. To effectively manage and restore these ecosystems, resource managers must consider long-term ecosystem baselines.
