Brightly Slacked Tight, It Sways, Molly Brooke Martin

Graduate Theses and Dissertations

Brightly Slacked Tight, It Sways is a body of work that investigates unpredictability and process-based making through collage and materially hybrid forms that combine natural and synthetic elements, operating between drawing, painting, and sculpture. Using familiar, readily available materials gathered from the studio, hardware store, and my surrounding environment, the work embraces improvisation as a generative force. Unpredictability keeps me in relation to the work, interrupting certainty, requiring responsiveness, and mirroring the shifting conditions of the natural world. I break, cut, and recombine sticks gathered from my yard and athletic tape from gymnastics, along with scrap drawings and paintings. Shaped …

Sweetly Somatic, Grace Edwards

Graduate Theses and Dissertations

The delight of biting into something sweet. The freedom of getting lost in the movement of your own body. The sensation of being completely enveloped by color. The flutter that rises in your chest when surrounded by abundance. Sweetly Somatic traces personal sensory experience across time, transforming ephemeral moments of joy into forms that capture enduring perseverance. Sculpted from fluxing ceramic materials, piped grout, and glass adornments, the works examine the elasticity of memory, both bodily and retrospectively. My bodily sensations are my most accessible form of joy, and a filter that all experiences move through.

Isolation, Purification, And Characterization Of Α-Galactosidase From Watermelon (Citrullus Lanatus), Christopher Henley Jr.

Chemistry & Biochemistry Undergraduate Honors Theses

The enzyme α-galactosidase is a type of glycosidase that removes galactose sugar units from larger molecules in cells. Compounds that inhibit glycosidases have been useful for understanding the structure and function of the enzymes they inhibit, and some have been used to treat certain diseases. Using inhibitors of α-galactosidase to study its characteristics and mechanisms may provide insights into its role in disease and its general utility. Advances in fields such as agriculture, sustainable fuels, and biomedicine may be facilitated by inhibition studies of α-galactosidase, but the current library of known inhibitors is relatively lacking. Obtaining α-galactosidase enzymes from chemical …

This thesis seeks to create empirical results to ground what has been a largely theoretical discussion about the effect of artificial intelligence (AI) on copyright law in the United States. AI has disrupted traditional ideas of creativity and expression, which are vital communication tools. Copyright is a regulatory agent to encourage the production of unique communication products by giving owners complete rights to their work. Copyright principles conflict with current AI model training practices. This research considers how AI literacy may provide insight into copyright knowledge and AI attitudes for prediction of how common law and AI regulation policy may …

Of The Land And Sea: A Critical Ecocultural Analysis Of Disney's Frozen And Moana, Maggie A. Andress

Communication Undergraduate Honors Theses

Within the modern era of performative inclusivity and widespread greenwashing, it is critical to examine popular media through an ecocultural lens to determine if said media is being handled responsibly as a social practice and if a discursive atmosphere is being created. This paper takes an ecocultural critical analysis of Disney’s worlds of Frozen and Moana, inspecting their treatment of the human, treatment of the more-than-human, and human/more-than-human relationships. This study finds that although both franchises have been broadly praised for cultural representation of Indigenous people groups, Disney’s failure to effectively acknowledge the intrinsic relationship between humankind and the …

"Deadly Imports": Populism, Demagoguery, And The Contemporary Rhetoric Of U.S. Immigration, Summer N. Wolfe

Communication Undergraduate Honors Theses

This project examines former CNN and Fox Business anchor Lou Dobbs’s meteoric success to understand his rhetorical choices and appeals surrounding immigration discourse in the United States. As the first rhetorical assessment of Dobbs’s immigration rhetoric, this project centers him as a key figure who defined how U.S. culture operates within immigration discourses. The project relies on Michael Calvin McGee's work on ideographs to perform a close textual analysis of news programs featuring Dobbs to understand how ideologies about immigrants and immigration are built, circulated, and maintained in the Right’s media ecology. The project advances three arguments about Dobbs’s anti-immigration …

Intraday Cotton Futures Price Responses To World Agricultural Supply And Demand Estimates (Wasde) News, Owen Mclane Tyrone

Graduate Theses and Dissertations

Price discovery in agricultural futures markets is augmented by information about supply and demand, leading markets to react when public reports are released. Effective price discovery in futures markets is vital to allocate physical commodities across time, synthesize information, and provide hedging tools. Price discovery in cotton markets is unique because it is less liquid than many other commodity markets. Therefore, our objective is to measure the initial price response in the cotton futures market to unanticipated ending stocks information in the WASDE report; then determine if markets continue to adjust after the initial price change. To meet our objective, …

Fret Studies On The Binding Of Fibroblast Growth Factor (Fgf) Proteins To The Hard Corona Of Cuins2-Based Quantum Dots, Colette Robinson

Graduate Theses and Dissertations

Fibroblast Growth Factor (FGF) has been shown to be an important protein in angiogenesis, which is critical in developmental biology and wound healing but has also been implicated in cancer metastasis. FGF interacts with an FGF Receptor (FGFR) to signal the onset of angiogenesis but the detailed mechanism of angiogenesis, and particularly its regulation, is still largely unknown. Imaging the interaction of FGF with FGFR in biologically-relevant environments, such as directly in cells, is key towards furthering this understanding and may eventually aid in the development of better cancer treatments. CuInS2/ZnS quantum dots (QDs) are an attractive fluorescent probe to …

Nadh Flim Reveals Cellular Bioenergetics And Mitochondrial Morphology During Drosophila Convergent Extension, Maria Espana Pena

Graduate Theses and Dissertations

Mitochondria are dynamic organelles that can fragment or fuse to support different bioenergetic demands and cellular processes, although the role of mitochondrial fission and fusion during embryonic development is not well understood. Fluorescence lifetime imaging (FLIM) of the mitochondrial cofactor NADH can be used to visualize mitochondrial networks and infer aspects of cellular bioenergetics in a label-free manner. We used NADH FLIM to test whether germband cells undergo changes in cellular metabolism during Drosophila convergent extension (CE)––a process in which hundreds of epithelial cells undergo coordinated intercalation to elongate the embryo. Contrary to our expectations, we did not observe significant …

The Reliance On Children In Atomic Bomb Literature, Chenyeng Vang

English Undergraduate Honors Theses

This paper explores the conventions of children’s literature, or what children embody in literature, and how it functions within atomic bomb literature in three ways: filling the gap of the unreliability of language, pushing past binaries through its queerness, and universalizing messages of peace to focus on a broad vision of a better future. Analysis involves atomic bomb literature written within the first five decades of the bombings, from 1945 to 1995. This research additionally seeks to answer the question: why children’s stories? This paper concludes that the dependence on children within atomic bomb literature hinges upon constructions of children …

A nationally representative sample (N = 205) completed an experiment embedded in an online survey. Participants were randomly assigned to read either a pleasure-based or pressure-based story about reproductive healthcare. Participants then reported their reactions, motivations, and willingness to support the nonprofit. Results indicated no significant difference in charitable support intentions across the two conditions, instead finding that partisan identification and value alignment were the key predictors of charitable support. The results also indicated that …

Bats And Bacteria: Infection Dynamics At The Human-Wildlife Interface, Isabella Katherine Deanglis

Graduate Theses and Dissertations

As the second most diverse mammalian order, bats host an array of pathogens, some of which are known to infect humans. Synanthropic bats share spaces with humans, resulting in bat-borne pathogen exposure. While most bat-borne disease research has focused on viral pathogens, bats host numerous bacterial pathogens with zoonotic potential. By integrating a global meta-analysis with field studies in Sub-Saharan Africa, I characterize the structural attributes that facilitate shared interfaces, the bacterial pathogens present in synanthropic bats of rural Kenya, and the physiological and environmental dynamics influencing odds of infection in these synanthropic bats. Finally, I evaluate the clinical relevance …

Evolutionary Conservation Of Midline Axon Guidance Activity Between Drosophila And Tribolium Frazzled, Piyasi Ghosh, Benjamin C. Wadsworth, Logan Terry, Timothy A. Evans

Biological Sciences Faculty Publications and Presentations

The regulation of midline crossing of axons is of fundamental importance for the proper development of nervous system connectivity in bilaterian animals. A number of conserved axon guidance signaling pathways coordinate to attract or repel axons at the nervous system midline to ensure the proper regulation of midline crossing. The attractive Netrin-Frazzled/DCC (Net-Fra) signaling pathway is widely conserved among bilaterians, but it is not clear whether the mechanisms by which Net and Fra promote midline crossing are also conserved. In Drosophila, Fra can promote midline crossing via Netrin-dependent and Netrin-independent mechanisms, by acting as a canonical midline attractive receptor and …

The Modern Sisyphus Blows Leaves: Attitudes And Impacts Regarding Leaf Litter Removal On A Suburban Campus, A. C. Nony, M. R. Mcclung, M. L. Reid

Journal of the Arkansas Academy of Science

Leaf litter habitat disruption in suburban spaces stems from the prevalence of “lawn culture,” that is, the accepted societal norm that land immediately surrounding humans or meant for human recreational use should be clean, tidy, controlled, and aesthetically pleasing, above other considerations. When leaf litter on residential and recreational lawns is cleared, it removes vital habitat for organisms of several taxa, especially species that rely on litter as a moisture and temperature-controlled substrate for overwintering. We administered an opinion survey to students, staff, and faculty at Hendrix College, a highly residential and suburban campus in Conway, Arkansas, to assess views …

New Host And Distributional Records For Helminth Parasites (Monogenoidea, Trematoda, Cestoda, Nematoda) Of Arkansas Reptiles (Testudines, Ophidia), C. T. Mcallister, C. R. Bursey, T. J. Fayton, S. E. Trauth, H. W. Robison

Journal of the Arkansas Academy of Science

Over the last decade or more, our collaborative research has provided noteworthy information on the helminth parasites of reptiles of Arkansas. Because several species still need to be surveyed from the state, some for the first time, there has been a general void of information on their parasites. We therefore examined 10 reptiles, including seven species/subspecies of turtles, as well as three species/subspecies of snakes for helminth parasites. Found were 24 taxa of parasites, including two monogeneans, 14 digeneans, one tapeworm, and seven nematodes. We document several new host and distributional records for these parasites from some reptiles of the …
