College of Graduate Studies: Theses & Dissertations

This thesis traces the development of Black and white Southern women’s pursuit of political power between the end of the Civil War and the ratification of the Nineteenth Amendment in 1920. Emancipation and the downfall of the antebellum planter aristocracy upset traditional Southern gender norms and opened new doors for women of both races in the political upheaval of Reconstruction. Though both Black and white women participated in the women’s club movement and joined women’s advocacy and charity groups following the Civil War, their work was distinctive both from each other and from other regional Progressive movements. The context of …

A Comparison Of Tung Oil Resin Reinforcements Using Fibrous Proteins And Peptides For Biological And Materials Applications, Parker L. Williams

College of Graduate Studies: Theses & Dissertations

In this study a tung oil based thermoset was reinforced with collagen and fibroin, and the resulting composites were analyzed for their physical properties. Tung tree seed oil is a great candidate for biobased polymer production because its triglycerides are primarily made of alpha eleostearic acid, a fatty acid with three conjugated carbon-carbon double bonds. These double bonds allow for mechanically strong crosslinking in the polymer. It has been observed that polymerized tung oil forms a gel. This issue has been addressed using divinylbenzene (DVB) and n-butyl methacrylate (BMA) as co-monomers. Similar bio-based polymers have been studied and tend to …

The Impact Of Controlling Language And Source Similarity On Psychological Reactance, Caroline Yarbrough

College of Graduate Studies: Theses & Dissertations

Persuasive health messages are frequently advertised throughout the pandemic to decrease the spread of COVID-19 while increasing the likelihood of immunity. However, research demonstrates that persuasive health messages may be ineffective because they have the potential to elicit psychological reactance. Reactance is characterized by a state of unpleasant motivational arousal and often occurs when individuals experience or perceive threats to their freedom, and it can be evoked through controlling language (Frey et al., 2021; Grandpre et al., 2003). Additionally, research has shown that similarity is associated with liking (Cialdini & Trost 1998) and people are often more inclined to comply …

However, maternal mortality may not account for health disparity factors, apart from access to quality care and physiological issues, which is a factor in pregnancy-related deaths, Pregnancy-related death, as defined by the US Centers for Disease and Control (CDC), is a death of a woman that occurs during or within one year of pregnancy that …

Nice Girls, Wild Women: The Call Of The American Wilderness And Feminine Rejection Of The American Dream, Alice Paige Dillard

College of Graduate Studies: Theses & Dissertations

Reflecting the inherently patriarchal nature of the colonization that birthed America as a nation, the American landscape English settlers sought to subjugate became connotated with the female gender through English colonial writing. American westward expansion gained greater allure than the overt appeal of conquest and agrarian industry when her untamed western landscape was likened to images of an unspent virginal bride or the breast of a nurturing mother. Thomas Morton likens the colonies of Maryland and Virginia to the Biblical figures of Leah and Rachel in his poem “New English Canaan” to demonstrate their equal worth as English colonies, though …

Submerged Aquatic Vegetation Response To Submarine Groundwater Discharge, Brielle K. Robbins

College of Graduate Studies: Theses & Dissertations

Ecosystem services provided by seagrass meadow communities in Florida Bay propagate economic opportunity and carbon sequestration among many other benefits. Recent seagrass die-off events have threatened Florida Bay’s ecosystem and its ability to provide these services. These impacts fuel ongoing research investigating the complex causes of seagrass die-offs. While previous research has described how water quality parameters can lead to seagrass die-offs, there is still much to be explored regarding the proximate causes for these water quality changes. The aquifers underneath the bay may hold the missing pieces in our understanding of die-off events, as submarine groundwater discharge (SGD) can …

Investigation Of Manufacturing Techniques For Magnetorheological Elastomers To Expand Feasibility In A Diverse Array Of Applications, Austin S. Robbins

College of Graduate Studies: Theses & Dissertations

Magnetorheological elastomers, or MREs, are smart composite materials with controllable physical and mechanical properties when introduced to an external stimulus of a magnetic field. The controllability of these properties is highly tunable by the selection of the elastomeric matrix, concentration of magnetically permeable particles, introduction of additives, and the alignment of the constituents during the curing process. The fabrication of MREs typically calls for a mold that is filled with an MRE mixture to create the final desired geometry after curing. These molds are frequently placed under a magnetic field which orients the micron sized magnetic particles along the magnetic …

The Effect Of Tempo On Prone Hamstring Exercise - An Exploration Of Unilateral Bias, Derick A. Anglin

College of Graduate Studies: Theses & Dissertations

Hamstring injuries are common muscle-skeletal injuries with a high recurrence rate. While unmodifiable risk factors (e.g., previous injury) vary, recent evidence has questioned the utility of eccentric exercise in preventing hamstring strains. Furthermore, whether eccentric exercise can transfer to sprinting’s kinetic and kinematic requirements is of question. Therefore, this investigation examines exercise tempo (fast vs. slow eccentric phase), movement strategy (bilateral vs. unilateral), and external load characteristics (coupled vs. independent) bias concentric (CON) and eccentric (ECC) biceps femoris (BF) mean electromyography (mEMG). METHODS: Twenty college-aged students aged 18 – 33 (M = 23.4, SD = 3.12 years) with …

The Effects Of Cucurbitacin B And Silmitasertib On Metastasis And Itga6 Using The Zebrafish Tumor-Xenograft, Alexandra Griffis

College of Graduate Studies: Theses & Dissertations

Ninety percent of cancer deaths are resultant from the metastasis of cancer cells. When cancer cells translocate through blood vessels or the lymphatic system, they may form tumors outside of their primary site. The processes of metastasis can begin quickly; after onset, metastasis is unforgiving, as it does not participate with the body’s physiological systems in an orderly way. In the past, our lab produced results indicating that a cell adhesion molecule, Integrin Alpha-6, may contribute to cancer cells' ability to metastasize. Integrins mediate interactions between the cell and the Extracellular Matrix (ECM), regulating cell attachment and cell migration. With …
