B-Cell-Specific Mhcii Promotes Host-Microbiome Symbiosis, Mary Melissa Roland

Theses and Dissertations

Classical major histocompatibility complex class II (MHCII) molecules are cell surface glycoproteins that bind and present peptide antigens on the surface of antigen presenting cells (APCs). MHCII:peptide complexes engage T cell receptors (TCRs) and CD4 co-receptors thereby facilitating cognate interactions between CD4+ T cells and APCs, which is responsible for the development of antigen-specific reactions and long-lived immunity; so called TD antibody responses. This is a critical step in the host’s response to pathogens, commensals, environmental stimuli and tumors. IgA is the dominant antibody isotype secreted into the gut and it is thought that most of the IgA in the …

Piratical Transportation: Highlighting Silences In Carolina’S Enslavement And Exportation Of Native Americans, Jordan Stenger

Theses and Dissertations

When Carolina colony was established, its early financial success was inherently bound to its enslavement and exportation of countless Indigenous people in the colonial pursuit of Native land, wealth, and enslaved labor. However, given the Indian slave trade was largely illegal in Carolina, how did colonists export Indigenous people? This study seeks to expand the land-locked historiography and explore how enslaved Indigenous people appear in the historical record across the Atlantic world. Utilizing term proximity as a methodological approach in reading historical records, and privileging Carolina’s black-market trade with pirates, I propose that the trade with pirates also included enslaved …

An Investigation Of The Galenic Influence On The Artistic Depiction Of Anatomical Concepts During The Renaissance, Fatima Amjad

Theses and Dissertations

The Renaissance era was a period marked by an intellectual and artistic resurgence in Europe, during which artists sought inspiration from Classical sources. This resulted in a move away from stylized medieval aesthetics and towards a renewed emphasis on accuracy and humanity in art. Renaissance artists developed art styles that emphasized perspective, proportion, and anatomy, creating more lifelike and naturalistic representations of the human figure and the natural world. The adoption of naturalism and individualism in the arts paired with the rediscovery and retranslation of ancient anatomical texts propelled artists and anatomists to deepen their understanding of the human body. …

A Study Of Single Molecule Detection With Graphene Hall Bars, Kenneth Stephen Stephenson

Theses and Dissertations

In 2007, detection of individual molecules with a solid-state gas sensor was reported for first time by Schedin et al. where they used micromechanically-cleaved graphene for their sensing material, which exhibits isotropic and homogeneous conduction [1]. However, despite the novelty and popularity of their work, it has never been repeated. Further, we found their associated calculations to be self-inconsistent by a factor of 103 . So, hoping to account for and resolve this discrepancy, we outline the plan we had to reproduce their experiment. We also justify any substantial modifications, particularly our choice to use epitaxial graphene instead. Then, we …

Oppa-Ng Gamsahamnita-Ng~~~: The Phonetics Of Nasal Cuteness In Korean Aegyo, Drew Michael Crosby

Theses and Dissertations

The term aegyo is often defined as a form of performative cuteness comprising a range of linguistic and non-linguistic behaviors (K. Moon, 2013; Puzar & Hong, 2018). Previous anthropological, discursive, and linguistic investigations (K. Moon, 2013; Puzar & Hong, 2018; H. Jang, 2021) identify it as a gendered practice associated with “modern and trendy young women in Korean mainstream culture” (K. Moon, 2017, p. 42), often used for requesting favors, maintaining social harmony, and gaining economic advancement (Manietta 2015; Puzar & Hong 2018). K. Moon (2013) asserts that the features that most prominently index aegyo are: rising-falling intonation (LHL%), the …

How Do They Do It: A Narrative Of Disabled Public School Instrumental Ensemble Conductors And Their Positive Working Relationships With Their Administrators, Lia Alexandria Patterson Snead

Theses and Dissertations

As the leader of the instrumental ensemble, the conductor’s role is important on and off the stage. Public school conductors have especially demanding jobs because they must act as a conduit between composer and ensemble as well as handle all administrative duties pertaining to running a music program. Subsequently, this results in a heavier workload than the average teacher. The demanding workload can add to any preexisting issues for disabled ensemble conductors who struggle at work due to insufficient support from their administrators. The lack of strong administrative support for disabled or impaired faculty and staff may be due to …

A Conductor’S Guide To Lucrecia Roces Kasilag’S Misang Pilipino (1965), Denise Ysabel Ellis

Theses and Dissertations

Composer Lucrecia Roces Kasilag (1918-2008) is a National Artist for the Philippines and a UNESCO International Artist of the World. Though she has many more accolades and triumphs to note, both national and international, Kasilag is not well known outside of her native Philippines. One factor that obscures this composer from the world is that much of her work is unpublished, as are other historical Filipino composers’ works.

Kasilag composed her first Misang Pilipino in 1965 to commemorate the 400^th year of Christianization in the Philippines, but multiple editions of the work were written and used for different occasions. …

Evaluating Health Awareness In Cancer Genetics Amongst The Black And African American Community In South Carolina, Annika Jaliya Gadson

Theses and Dissertations

Historically minoritized individuals are underrepresented in genomic research which limits the ability to fully understand genetic variation within the population (Sirugo et al., 2019). This creates bias that questions the effectiveness of guidelines for genetic testing, predictive risk values, and medical management. Disparities in cancer genetics may be attributed to historical events that have cultivated mistrust in research and medicine, institutional bias, provider skepticism in patient reporting of medical symptoms, and limited access to genetic testing (Saulsberry et al., 2013). More exploration is needed to better understand how to increase access and awareness of cancer genetic services to Black and …

Stylistic Variation Of Gullah Geechee Language Practices In Coastal Tourism Contexts, John Kibler Mccullough

Theses and Dissertations

This dissertation examines the language practices and ideologies of Gullah Geechee (GG) tour guides in Charleston, South Carolina, particularly analyzing how language stylization is used by tour guides in the construction of personae as intercommunity culture and language brokers. Often, indigenous cultural artifacts are commodified through the setting of the tourism industry for consumption by outsiders; Gullah Geechee, a Sea Island creole language spoken along the southeastern United States coast, is directly affected by this characteristic of tourism. GG has been exposed to rapid de-isolation in the past 80 years; this exposure has brought isolated enclaves of GG communities into …

A Mixed Method Study Of How Teachers’ Racial Bias Relates To Student-Teacher Relationships, Tasha Marie Childs

Theses and Dissertations

Despite the important role public schools serve in students’ lives, schools are at the center of racial, socio-economic, and political divide and the epicenter of traumatic events for students who are marginalized based on their racial or ethnic identity. While ample research has demonstrated educational inequities for these students, no study to date has examined the impact of teacher racial bias on the quality of student-teacher relationships within the context of the United States (US) pre-Kindergarten through twelfth grade (PK-12) schools. A cross-sectional convergent mixed methods study was conducted to examine interpersonal racism in the classroom, and to specifically answer …

Sparse Partitioned Empirical Bayes Ecm Algorithms For High-Dimensional Linear Mixed Effects And Heteroscedastic Regression, Anja Zgodic

Theses and Dissertations

Variable selection methods in both the frequentist and Bayesian frameworks are powerful techniques that provide prediction and inference in high-dimensional linear regression models. These methods often assume independence between observations and normally distributed errors with the same variance. In practice, these two assumptions are often violated. To mitigate this, we develop efficient and powerful Bayesian approaches for linear mixed modeling and heteroscedastic linear regression. These method offers increased flexibility through the development of empirical Bayes estimators for hyperparameters, with computationally efficient estimation through the Expectation Conditional-Minimization (ECM) algorithm. The novelty of these approaches lies in the partitioning and parameter expansion, …

Immunohistochemical Investigation Of Wwp1 Expression During Embryonic Heart Development And Its Implications For Cardiac Aging, Savannah L. Bowers

Senior Theses

Cardiovascular disease is the leading cause of mortality globally, with the aging population being most vulnerable. Cardiomyocytes and cardiac fibroblasts mediate pathophysiological changes of cardiac aging including interstitial fibrosis, left ventricular hypertrophy, lethal arrhythmias, and eventual culmination in heart failure. Interestingly, subclinical congenital heart disease and hypertrophic cardiomyopathy, originating in embryonic development, induce accelerated cardiac aging. The diverse developmental origins of cardiac fibroblasts suggest that perturbations in gene expression within this heterogeneous cell population during embryonic heart development have significant consequences for cardiac aging. Previous studies implicate the E3 ubiquitin ligase WWP1, a post-translational regulatory protein, in accelerated cardiac aging. …

Next, I undergo the same process for how incarceration and how it affects economic outcomes of individuals, through the debt cycle, the drain of household resources, limited/lack of pay while in prison, and difficulty in finding employment after release from prison. I follow this by connecting incarceration to drug use by writing about the background on the United States’ incarceration rates and link to drug enforcement and systemic …

A New Atticus Is Afoot: The Portrayal Of Lawyers In Popular Culture, Anna Thrush

Senior Theses

This project analyzes the stereotypical image of lawyers in popular culture, focusing on either overly demonic or unrealistically heroic. Both stereotypes that are common portrayals of attorneys in popular culture are unrealistic and deny society a true comprehension of the profession. Popular culture has molded the image of lawyers to the characteristics that sell, rather than focusing on a realistic portrayal. Therefore, popular culture creates a falsely dramatized image of attorneys to generate revenue, putting the reputation and future of the profession as risk. These stereotypes are exemplified in this project through a close literary analysis of lawyer characters from …

Toxic Positivity And Perceptions Of Mental Health, Madeline E. Feltner

Senior Theses

My thesis concerns how toxic positivity, especially the type we commonly see on social media, can affect perceptions and stigma around mental health issues on college campuses. Toxic positivity is the belief that a person should always maintain a positive mindset, no matter what situation they are in, and invalidates negative emotions. Previous research shows that toxic positivity can have a negative effect on mental health, but in this thesis, I study how toxic positivity affects perceptions about others with mental health issues, willingness to interact with those with mental health issues, and self-perception. It is important to research this …
