Population Genetic Diversity In Two Biological Systems, Alyson Emery

Electronic Theses and Dissertations

Population genetic analysis can be used to answer questions about population structure and composition in many biological systems. Recent improvements to sequencing technologies have made population genetic studies more accessible than ever before. Many of the same techniques can be applied to different biological systems, but some analyses may differ depending on how genetically divergent the populations in question are. Here, we describe two unique projects using next-generation genome sequencing, each looking at population structure at different levels of genetic divergence: the first involved determining interspecific population structure between two species of hybridizing field cricket using a novel sequencing method, …

On Salvation And Genre: Fast Sermons In Seventeenth-Century New England, Daniel Patrick Mcgee

Electronic Theses and Dissertations

The fast sermon is an important and overlooked genre in the literary history of colonial New England, one which complicates theories about American puritanism underwritten by the imprecise narrative construct of the jeremiad. This thesis will argue that preachers used fast sermons to shape their communities, respond to major events, and provide competing interpretations of Congregationalist doctrine throughout the seventeenth century. Borrowing from the methodologies of new formalist criticism and Louis Althusser’s theory of material ideology, it will examine common themes, motifs, and rhetorical demands in John Wheelwright’s 1637 Fast Sermon, Thomas Shepard’s 1645 Wine for Gospel Wantons, …

Just Say Gay: An Exploration Of Authenticity And Connection; Queer Identified Therapists’ Lived Experiences Of Identity-Based Self-Disclosure, Courtney Dunne

Electronic Theses and Dissertations

The current sociopolitical climate in the United States continues to reinforce the complexities and nuances that mental health providers face when facilitating therapy. Over the past few years, anti-DEI legislation has aimed to control the narrative in educational and therapeutic settings regarding what therapists and educators are permitted to teach and share about themselves (Flannery, 2024). At the same time, anti-LGBTQ+ rhetoric continues to dominate the media and further marginalizes individuals whom are in the queer community. In turn, LGBTQ+ individuals continue to face an increased risk for homelessness, substance use disorders, and suicide, which particularly has impacted LGBTQ+ youth …

Impact Of Dialogic Reading Intervention On Language And Literacy Development Of Young Dual Language Learners, Ekta Ghosh

Form And Matter In Kant's Theoretical Philosophy, Aaron Higgins-Brake

Electronic Theses and Dissertations

This dissertation examines the use of the terms “form” and “matter” in Kant’s theoretical philosophy from his earliest publications up to the Critique of Pure Reason (1781). I argue that these two concepts have received unfortunately little attention in the development of Kant’s thought and in his mature writings. I begin in Chapter One by examining his increasing use of them in his pre-critical writings culminating in the Inaugural Dissertation (1770), where he first develops his theory of space as a form of intuition. Then in Chapters Two to Five, I examine his account of them in his accounts of …

Made In The Divine Image: The Interface Of Boki Concepts And Pontifical Biblical Commission's Reading Of Genesis 1-2, Luther Raymond

Electronic Theses and Dissertations

Certain images facilitate tailoring our perception of ourselves and the rest of creation in positively practical ways, but others lead us astray and disfigure our relationships. Christians acknowledge that humans are made in the divine image, yet we allow the domineering presence of destructive frames and perceptions to counter our being divine image-bearers. This dissertation explores the intersection of the Boki Beri-be/Keredede motif and the language of the presentation of Genesis 1-2 in the 2019 Pontifical Biblical Commission Document What Is Man? calling for a recognition that humans are the embodiment of the divine presence in creation with a calling …

Making And Breaking Bonds: Studying Intrinsic Chemistry In The Gas-Phase, Luke Metzler

Electronic Theses and Dissertations

The nature of chemical interactions can be difficult to ascertain in the condensed phase; chemistry can be observed, but with the plethora of variables such as solvation, mixes of counter-ions, and complex equilibria, the true intrinsic chemical properties of a given chemical species may be obfuscated. By conducting research in the gas-phase, many of these variables can be reduced, if not eliminated entirely, which can allow for the careful observation of the true physical phenomena driving chemical reactivity.

The research presented herein focuses on the use of ion-trapping (specifically in a linear ion trap) as a method for unveiling the …

Uptake Of Extracellular Vesicles Into Brain Endothelial Cells And Development Of Motor Neuron-Derived Extracellular Vesicles For Amyotrophic Lateral Sclerosis, Jhanvi Rajan Jhaveri

Electronic Theses and Dissertations

Extracellular vehicles (EVs) are an emerging class of drug carriers and are primarily reported to be internalized into recipient cells via a combination of endocytic routes such as clathrin-mediated, caveolae-mediated and macropinocytosis pathways. In part one of this thesis, (1) we investigated potential effects of homotypic vs. heterotypic interactions by studying the cellular uptake of homologous EVs (EV donor cells and recipient cells of the same type) vs. heterologous EVs (EV donor cells and recipient cells of different types) and (2) determined the route of EV internalization into low pinocytic/hard-to-deliver cell models such as brain endothelial cells ( …

Delivery Of Mitochondria-Containing Engineered Extracellular Vesicles To The Blood-Brain Barrier For Ischemic Stroke Therapy, Kandarp Dave

Electronic Theses and Dissertations

Ischemic stroke is the second leading cause of death worldwide, and the lack of effective treatment options is an unmet clinical need for stroke survivors. Ischemic stroke-induced oxygen-glucose deprivation (OGD) in the affected brain tissue leads to mitochondrial dysfunction and adenosine triphosphate (ATP) depletion in the brain endothelial cells (BECs) lining the blood-brain barrier (BBB). ATP deprivation in the BECs dysregulates actin cytoskeleton dynamics, resulting in BBB breakdown. Restoration of blood flow (i.e., reperfusion) upon the first-line stroke treatment further leads to BBB breakdown and widens the paracellular spaces between BECs. …

Place And Placelessness: An Ecocritical Approach Towards The Mountain Imagery In Country Music, Siyuan Ma

Electronic Theses and Dissertations

Drawing upon cultural geographer Yi-Fu Tuan’s frame of place and placelessness, this ecocritical project explores how the mountain landscapes serve to construct regional, national, cultural, spiritual, religious, even racialized identities in various human societies. Using the U.S. country music as a primary example, I argue that what country music fundamentally draws from the imagery of the Appalachian Mountains is not the Anglo-Saxon ballad music or pastoral lifestyle of/from the mountains, but the powerful sense of place and placelessness (arguably only) the mountainous scenes are capable to provoke. This exploration serves to illuminate the commonalties between humanities of different cultures and …

Chinese Tallow Long-Term Impact On Stand Dynamics In A Bottomland Hardwood Forest Following Vegetation Management, Nicklaus R. Langlois

Electronic Theses and Dissertations

Chinese tallow (Triadica sebifera (L.) Small) is an invasive tree known to have negative impacts on bottomland hardwood forests. Chinese tallow is proficient in reproducing and surviving in bottomland hardwood forests because it is more flood and shade tolerant than most native trees. The long-term effectiveness of Chinese tallow control is an important topic to research as only a few long-term studies of Chinese tallow control have been conducted. A 10-year re-measurement of 22 paired plots installed in 2012 on the Pineywoods Mitigation Bank near Diboll, Texas following herbicide treatments examined Chinese tallow and native tree stand structure. Each …

I describe my methodology for breaking the photographic materials from their original order, going against typical archival processing methodologies, with the aim that the collection will more accurately represent the city’s strategic displacement of Black Louisvillians and civic prioritization of capital efficiency over community. This work emphasizes the …

Furthering Ascidian Taxonomy Using Molecular Biology, Nicholas Gulnick

Electronic Theses and Dissertations

Ascidians are our closest invertebrate relatives and comprise nearly 3,000 species separated into three orders: Aplousobranchia (most speciose), Stolidobranchia, and Phlebobranchia (least speciose). Ascidians can be classified as either solitary or colonial organisms. Species delimitation using morphological characters alone has had varied results. Well known, widely distributed, morphological species have turned out to be catch all species comprised of several cryptic species. Molecular markers can help mitigate some of the issues presented by strictly using morphological observations, including resolving the status of cryptic species, and accessing the expert knowledge required to identify a species. By incorporating molecular markers and pairing …

Variability In Nutrient Concentrations Across Regions Of The Winyah Bay River Plume, Anne Mackenzie Gossman

Electronic Theses and Dissertations

River plumes are one of the few large-scale features responsible for transporting particulates and terrigenous materials to coastal oceans. Macro-nutrients, such as dissolved inorganic nitrogen (DIN) and phosphorus (PO43-), are basic requirements for marine food webs. Due to the plumes’ ability to transport large quantities of these constituents, these systems contribute heavily to coastal productivity. This study focuses on the dynamics of the Winyah Bay river plume located in Georgetown, South Carolina. River plumes, including the Winyah Bay plume, are dynamic systems whose structures are comprised of a multitude of regions and features including the source, lift off, near-field, mid-field, …
