Joseph Bologne, Chevalier De Saint-Georges' "Overture" From L'Amant Anonyme: A Transcription For Wind Ensemble, Lindsay H. Guilbeau

Dissertations

The purpose of this dissertation was to transcribe the orchestral Overture from Joseph Bologne, Chevalier de Saint-Georges’ only opera with a surviving score, L’Amant Anonyme, for wind ensemble. Transcribing this portion of L’Amant Anonyme by a Black composer from the Classical era not only provides the opportunity to expose the wind band community to an underrepresented composer but also gives this work an additional medium to be performed in. Bologne was dubbed “Le Mozart Noir” or “Black Mozart” by French concertgoeres of the time, and the nickname has not yet disappeared. This title, whether or not intentional, pus him in …

Elucidating The Mechanism Of Interleukin-17a Signaling In The Pathogenesis Of West Nile Virus, Farzana Nazneen

Dissertations

West Nile Virus (WNV), a neurotropic flavivirus transmitted by mosquitoes, is a leading cause of viral encephalitis in the United States and remains a significant public health concern. Unfortunately, no vaccine or therapeutic intervention is available against WNV infection. Previous studies, including ours, demonstrated that interleukin-17A (IL-17A) signaling increases the cytotoxic potential of CD8⁺ T cells to facilitate WNV and parasite clearance; however, the molecular mechanism is not understood. IL-17 receptor C (IL-17RC) is an obligatory co-receptor with IL-17 receptor A (IL-17RA) for signaling induced by IL-17A, IL-17A/F, and IL-17F. In this study, we found that IL-17RC deficient ( …

Artificial Intelligence, Machines, Devices, And Robots: Mobilizing Humanness And Intelligence In The American Techno-Landscape, Carlos A. Batres

Dissertations

This dissertation is an ethnographic inquiry of artificial intelligence (AI) in the techno-landscape of three major metropolitan areas in the United States. It traces the ways in which both experts and non-experts talk about their interactions with AI via machines, robots, and other devices, and how the ways in which people deal with AI-technologies have come to shape how we think about our own ways of going about doing things. The goal is to discern what the social ramifications of this technology may be as relationships and relations are formed betwixt and between people and artificially intelligent things.

Mutual Enjoyment: A Levinasian Conception Of Freedom, Aaron Darrisaw

Dissertations

Established scholars typically regard the philosophy of Emmanuel Levinas as one that offers a morally elevated, and even religious, sense to the meaning of ethics. He uses many descriptions to encapsulate his understanding of ethics, but a common shorthand is “the calling into question of freedom.” This dissertation aims to answer the following question: What becomes of freedom after it has been submitted to Levinas’s ethical critique? Engaging this question emphasizes the distinctively political significance of Levinas’s philosophy, a significance that is often regarded as lacking. However, my project treats freedom as a unique prism through which to interpret Levinas’s …

Role Of B Cell Mediated Immune Response During Skin Atopic Dermatitis Disease, Hidaya Mohammed Abdul Kader

Dissertations

Atopic dermatitis (AD) is the most prevalent non-infectious skin allergy affecting approximately 10-30% adults and 40% children worldwide. It is clinically characterized by eczematic lesions and elevated IgE levels and is a multifactorial disease that is heterogenous in nature. AD results in a dominant Th2 polarized immune response. Until date, there is no cure for this disease. B cells are key players of humoral immune responses and contribute significantly to allergic responses through IgE secretion. However, recently a subset of B cells termed regulatory B cells (Bregs) have been reported to provide protective role by the secretion of anti-inflammatory cytokine …

Mouse Mammary Tumor Virus (Mmtv) Genomic Rna (Grna) Packaging: Selective Grna Encapsidation Is Facilitated By Long-Range Interactions (Lris) That Facilitate Specific Gag Binding, Suresha G. Prabhu

Dissertations

Mouse mammary tumor virus (MMTV) is a betaretrovirus that induces breast cancer and sporadically, T-cell lymphomas in mice. MMTV serves as a pertinent model for elucidating the mechanism(s) of oncogenesis and the genetics associated with the development of mammary tumors. Being a rodent retrovirus, MMTV is phylogenetically distant from human and other primate retroviruses; thus, positioning it ideally as a potential vector of choice for human gene therapy. This may circumvent safety concerns such as recombination with other related endogenous human retroviruses. In addition, MMTV is distinct from most other retroviruses, but similar to lentiviruses, in that it has the …

Fabrication And Evaluation Of Multicomponent Biomimetic Scaffolds For Bone Tissue Engineering, Mozan Osman Hassan

Dissertations

Bones have an inherent ability to remodel, but critical-size defects can hinder regeneration, leading to delayed healing or non-union fractures. Traditional bone grafts have limitations, such as donor site morbidity and immune rejection, driving the need for synthetic bone substitutes. Bone tissue engineering (BTE) addresses this by developing biomimetic scaffolds that replicate bone properties. This research aimed to fabricate composite scaffolds from strontium (Sr) and zinc (Zn) doped nano-hydroxyapatite (nHAp), collagen, and poly(lactide-co-glycolide) (PLGA). Different doping percentages of Sr/Zn (1%, 2.5%, 4%) were used to fabricate the scaffolds using supercritical CO2 (ScCO2) and electrospinning techniques. Scaffolds were then analyzed for …

Identifying And Characterizing Cognitive Profiles In Midlife Females: A Latent Profile Analysis, Hannah Hagy

Dissertations

Females are at two-thirds greater risk of developing Alzheimer’s disease (AD) than males.

Previous studies propose that interpersonal violence and loss, parenting, and attachment each individually contribute to child and family distress. The following studies aimed to further explore these effects across and within various generational groupings. The first study explored exposure to community violence at the parent level and at the child level in an attempt to understand how such stress impacts parents’ perceptions of family functioning in African-American and Latine families. Findings suggested that family functioning is weakened the most when both a parent and adolescent are exposed and when just a parent was exposed. The second study examined differences in …

Warm Bodies, Strong Attachments, And The Search For Better Bonds: The Politics Of Human-Animal Entanglements In U.S. Fiction And Media, John Charles Hawkins

Dissertations

This dissertation describes human-animal relationships as sites of political longing and meaningful failure in the context of twentieth and twenty-first U.S. fiction and media. I locate three tendencies of imagination prevalent in writing about bonds between humans and other animals: collaboration in regional modernity, refamiliarization in consumer capitalism, and transformation in rationalist patriarchy. These expressions of desire for a different way of relating, I argue, open important windows into the places where current power structures generate suffering and distress. I also emphasize the compelling but imperfect nature of these expressions. The texts and images in this dissertation offer attempts to …

Differences Are Not Deficits: Women Introverting While Black Through The Ascent To Executive Leadership In Higher Education, Jeri A. Bingham

Dissertations

Diversity of personality type in the workplace can lead to improved morale and productivity when organizations acknowledge and support the attributes and differences of employee behaviors and characteristics. Black women executives identifying as introverted who lead with their authentic personas and intersected marginalized identities, benefit employers, employees, students, and the institution’s brand and bottom line. Introversion and extroversion, ways to describe diversity of personality type, and each having different connotations in office culture, are relevant to this exploration as literature suggests that the population of both personality types is almost evenly distributed. The implications of judgement and the association to …
