Social Ecological Resilience, Social Capital, Anomie And The Impact Of Covid-19., Kevin Pacifico Gonzaga

Electronic Theses and Dissertations

From climate change to racial tension and income inequality, many difficulties face the United States and those who live within its borders. The extreme and increasing political polarization in the United States as well as the impact of the COVID-19 pandemic have only made these challenges more difficult to address. In this complex web of adversity, the concept of resilience is important to study. Resilience may be broadly defined as the ability to “bounce back” or return to adaptive functioning after experiencing significant adversity or challenges (Smith et al., 2008). Better understanding how resilience functions and the general state of …

Emancipation: Centering Black Parent Voices In The New Orleans Charter School Experiment, Nicole Moliere

Electronic Theses and Dissertations

This phenomenological study explored Louisiana legislative charter school policies and the extent to which those policies empowered Black public-school parents in the New Orleans charter school experiment (NOCSE). Parent empowerment, the sharing of power with parents, has been a missing component both in scholarly literature and in charter school policy and implementation (Ferlazzo, 2011; Hsiao et al., 2018, Murray et al., 2013). Using semi structured interviews, the results of this study yielded three themes related to Black parent empowerment (BPE) and the public-school struggles Black parents face in an all-charter district. Based on the research findings, this study revealed that …

The P-Adic Numbers And Conic Sections, Abdelhadi Zaoui

Electronic Theses and Dissertations

This thesis introduces the p-adic metric on the rational numbers. We then present the basic properties of this metric. Using this metric, we explore conic sections, viewed as equidistant sets. Lastly, we move on the sequences and series, and from there, we define p-adic expansions and the analytic completion of Q with respect to the p-adic metric, which leads to exploring some arithmetic properties of Qp.

Youth-Friendly, Person-Centered Contraceptive Care For Adolescents: Exploring The Capacity Of Safety-Net Clinics In Alabama And South Carolina, Kristen Surles

Electronic Theses and Dissertations

Introduction: In recent years, high quality contraceptive care for adolescents has shifted away from tiered effectiveness counseling and toward youth-friendly, patient-centered counseling (YFPCCC). YFPCCC is essential in the South, which has higher rates of sexual activity, lower rates of contraception use, and higher teen birth rates. This study examined Southern clinics’ characteristics which support YFPCCC and youth’s perceptions of the contraceptive care they receive.

Methods: This mixed methods study examined secondary data collected in two surveys and primary data collected through key-informant interviews. The first survey examined clinic characteristics impacting YFPCCC, and the second survey examined adolescents’ (aged 16-24) perspectives …

The Stringent Response In Pseudomonas Aeruginosa Influences The Phenotypes Controlled By The Gac/Rsm System, Michael Shawn Hooker

Electronic Theses and Dissertations

Pseudomonas aeruginosa is a ubiquitous, opportunistic pathogen that causes acute and chronic infections. Infection is typically initiated via motile and virulent strains. After exposure to stressors, acute infections make both genotypic and phenotypic switches to a chronic, sessile strain. This is due to intricate regulatory networks directing gene expression in response to stressors. One network, GacA/GacS, has been established to control virulence factors. The stringent response of bacteria is mediated by alarmones produced primarily by RelA which responds to starvation.

To study the effect of the stringent response on the virulence switch. A series of experiments were run in both …

Extracting Topography From Historic Topographic Maps Using Gis-Based Deep Learning, Briar Pierce

Electronic Theses and Dissertations

Historical topographic maps are valuable resources for studying past landscapes, but they are unsuitable for geospatial analysis. Cartographic map elements must be extracted and digitized for use in GIS. This can be accomplished by sophisticated image processing and pattern recognition techniques, and more recently, artificial intelligence. While these methods are generally effective, they require high levels of technical expertise. This study presents a straightforward method to digitally extract historical topographic map elements from within popular GIS software, using new and rapidly evolving toolsets. A convolutional neural network deep learning model was used to extract elevation contour lines from a 1940 …

Inhibiting Survival Of Salmonella During Desiccation Through The Use Of Naturally Occurring Signals, Joseph Headrick

Electronic Theses and Dissertations

A rising problem in agriculture is the increase of antibiotic-resistant Salmonella cases associated with chicken eggs, which transmit infection to humans. To counter this, new approaches to combat Salmonella in chickens and desiccated on eggshells are vital in the prevention of human foodborne illness. Disrupting signaling pathways with naturally occurring compounds provides a potential novel avenue for prevention of Salmonella infections, as this would disrupt sensing of these environments and inhibit subsequent optimal gene expression. Starting with signals identified in previous studies, salicylic acid was found to inhibit Salmonella desiccation survival on both eggshells and plastic. To expand upon this, …

Mankind Is Machine: A Monstrous Posthuman Reading Of Philip K. Dick’S Selected Works, Gabriel Davis

Electronic Theses and Dissertations

The works of Philip K. Dick act as an ideal template for readers to explore what it means to be human in a technologically dominated world. Dick’s emphasis on the usage of androids and artificial intelligence as literary monsters allows for a posthuman reading of the traditional literary monster, notably in how their uncanny nature and behavior helps reveal the synthetic tendencies of humanity. In Do Androids Dream of Electric Sheep?, “Imposter,” and “I Hope I Shall Arrive Soon,” each narrative incorporates artificial intelligence and androids acting as others to reveal the machine-like qualities of Dick’s human characters. This …

Comparative Characteristics Of Integrin Αdβ2 Binding To Native Fibrinogen And Fibrinogen Modified By Dha Oxidation During Inflammation, Ajibola Ilesanmi

Electronic Theses and Dissertations

2-ω-carboxyethylpyrrole (CEP) is a product of docosahexaenoic acid (DHA) oxidation, which forms covalent adducts with different proteins. CEP-modified proteins can interact with macrophage receptor, integrin αDβ2. This study aims to compare αDβ2 binding to its physiological ligand, fibrinogen, and CEP-modified fibrinogen, which is formed during inflammation. We hypothesize that modification of fibrinogen changes its ligand-binding properties to integrin αDβ2 which can affect macrophage migration and retention. Recombinant αD I-domain and αDβ2-transfected HEK293 cells were used for the experiments. Using biolayer interferometry, we found that the affinity of αD I-domain binding to fibrinogen-CEP was higher than fibrinogen and inhibited by the …

Neuronal Or Intestinal Knockdown Of C. Elegans Nadk-1 Decreases Oxygen Consumption And Reactive Oxygen Species, Jake Regan

Electronic Theses and Dissertations

Reactive oxygen species (ROS) such as H2O2 can damage cellular components and are formed as a byproduct of mitochondrial oxidative metabolism. Studies using the nematode C. elegans have found that increasing ROS during development or early adulthood can extend lifespan, while increasing ROS during later adulthood normally decreases lifespan. NADPH provides the reducing power for several cellular antioxidants and is synthesized in a two-step reaction from NAD+ with the first step being catalyzed by NAD kinase (NADK). In this study, the effects of knocking down C. elegans cytoplasmic NADK, nadk-1 globally or in a neuron or intestine-specific manner starting from …

Preference For Abstinence-Based Recovery And Public Stigma Toward Substance Use Disorders, Diamond Meadows

Electronic Theses and Dissertations

The present study drew from the publicly available Amerispeak survey (n = 6,515) and examined public stigma towards different substances, the relationship between preferences for abstinence-based recovery and stigma toward each substance, and whether perceived dangerousness of substances moderates the relationship between preferences for abstinence-based recovery and public stigma. The results indicate that the general public has greater stigmatizing attitudes towards methamphetamine use disorder than cocaine use disorder, opioid use disorder, and alcohol use disorder. Furthermore, a preference for abstinence-based recovery was associated with greater stigmatizing attitudes toward all SUDs. The perceived dangerousness of a substance did not moderate the …

Cyclic-Di-Gmp Regulates Salmonella Typhimurium Infection Of Epithelial Cells And Macrophages, Abdulafiz Musa

Electronic Theses and Dissertations

Regulation of the bacterial second messenger cyclic-di-GMP in Salmonella Typhimurium allows it to delicately alter phenotypes to optimize invasion and survive intracellularly in epithelial cells and macrophages to become virulent and cause infection. Cyclic-di-GMP concentration is regulated by the presence of external stimuli, sensory diguanylate cyclases (DGCs) and phosphodiesterases (PDEs), and cyclic-di-GMP binding effectors. Previous studies established that maintenance of low cyclic-di-GMP concentrations is required for survival in macrophages, and that deletion of 3 active PDEs reduces this survival. Here I showed that these 3 PDEs also influenced the infection of epithelial cells. Further studies re-established the decreased survival in …

Führer And Father In Flux: Fascism And Desire In The Works Of George Saunders, Don Delillo, And David Foster Wallace, K. Tyler Wick

Electronic Theses and Dissertations

Since the end of World War II, the possibility of fascism and totalitarianism as a global threat continues to proliferate in American art and literature to the point that many individuals paradoxically desire the very things that seek to control them. Postmodern literature often portrays fascism and totalitarianism as it exists under contemporary capitalist systems as a multiplicity of discreet machines operating within objects of desire. These objects are complicated by the 24-hour news cycle and the popularity of solitary, on-demand entertainment that in turn mediates the desires and fears of a population through strict control of information. This thesis …

Trend Analysis, Emerging Hot Spot Analysis, and a time series revealed three significant waves in both age groups. Therefore, Change Point Detection at the county level was completed using six defined change points to identify the wax and wane of the three COVID-19 waves. Hierarchical Cluster Analysis grouped counties with similar change points into six clusters. No spatial pattern was observed in distribution of the six clusters, however, when each change point was evaluated separately, spatial autocorrelation was present, …

Peer Perceptions Of Parent-Students Seeking Higher Education, Alexandria M. Wall

Electronic Theses and Dissertations

With a growing number of parents pursuing academia, it is imperative that researchers understand the social environment in which parent-students function. Stereotypes of parent-students may be held by peers, faculty, and other educational supervisors. Across two previous independent studies, evidence and rationale were provided to suggest that both positive and negative perceptions of parent-students exist, with noted differences between gender. The purpose of the current 2x2x2 between-subjects study was to analyze the social perceptions of students enrolled in higher education as varied by parenthood status, age, and gender. The social perceptions included measures accounting for perceptions of intelligence and academic …

Brand-Funded Documentary Films And Climate Change: An Aristotelian Rhetorical Analysis, Matthew Rossetti

Electronic Theses and Dissertations

This paper examines the concept of brand-funded documentaries that center on the issue of climate change and uses Aristotle’s Rhetorical Triangle to better understand how the films use rhetoric in communicating their message. A rhetorical analysis was conducted using four brand films from Amazon, Corona, Patagonia and REI and the results are intended to demonstrate the best methods of persuasion and the most effective rhetoric utilized in brand-funded documentaries. Because brand-funded documentaries not only make an argument about a particular issue, in this case climate change, but also must communicate a particular brand’s values and commitments, examining the rhetoric in …

Polyamory - The Multiple Complexities Of Multiple Partners, Vianna Isbister

Electronic Theses and Dissertations

This study is an exploration of the relationship between polyamory and how polyamorous people communicate about their relationship dynamics. Drawing from six individual interviews and one focus group, the author compares key language that appears in previous research to the language created by the study participants. Utilizing grounded theory for the analysis, results indicate that the language choices of sexual identity, sexual orientation, and/or relationship model are not sufficient for singularly encompassing a poly experience. Findings indicate that individuals who identify under the umbrella of consensual non-monogamy (CNM) may use the term "polyamory" to describe their own relationship dynamic or …
