Male students of color often receive harsher disciplinary consequences than their same age White peers. Disproportionate discipline practices have existed within the education system for years, primarily due to a historical systemic issue of implicit bias due to race. One intervention used to quell some of these disparities is Restorative Practices. This program evaluation study used Restorative Practices as an intervention to determine the extent that it could close the discipline gap in one South Carolina high school. Using a concurrent nested mixed method design, I analyzed and synthesized historical agency data to answer the first research question regarding the …

Robust And Trustworthy Deep Learning: Attacks, Defenses And Designs, Bingyin Zhao

All Dissertations

Deep neural networks (DNNs) have achieved unprecedented success in many fields. However, robustness and trustworthiness have become emerging concerns since DNNs are vulnerable to various attacks and susceptible to data distributional shifts. Attacks such as data poisoning and out-of-distribution scenarios such as natural corruption significantly undermine the performance and robustness of DNNs in model training and inference and impose uncertainty and insecurity on the deployment in real-world applications. Thus, it is crucial to investigate threats and challenges against deep neural networks, develop corresponding countermeasures, and dig into design tactics to secure their safety and reliability.

Carbon "Quantum" Dots: Structures, Properties, And Issues, Weixiong Liang

All Dissertations

Carbon dots (CDots) are small carbon nanoparticles (CNPs) with effective surface passivation. The effective passivation has been achieved by the surface functionalization of pre-existing CNPs with organic molecules, mostly molecules containing primary or secondary amine moieties. In the studies highlighted in this dissertation, CNPs were functionalized by selected organic molecules, including especially the use of radical addition reactions, to generate CDots with strong absorption and bright fluorescence emissions. A good demonstration of the approach was the N-ethylcarbazole (NEC) radical addition to CNPs under microwave irradiation. Spectroscopy and microscopy methods were employed to characterize the resulting NEC-CDots, and the results …

An Investigation Into The Structural Features That Control Factor Xiii Stability And Substrate Specificity., Rameesa Darul Amne Syed Mohammed

Electronic Theses and Dissertations

Factor XIII (FXIII) is a transglutaminase enzyme with multiple physiological roles that is found in plasma and cells of bone marrow origin. The catalytic A subunit (FXIII-A) is made of an N-terminal activation peptide (AP), β-sandwich, catalytic core, and two β-barrel domains. FXIII crosslinks the sidechains of glutamine (Q) and lysine (K) residues across plasmatic and cellular substrates. Because of its involvement in clot stabilization and determining fibrin clot size, FXIII-A is regarded as a target for developing new anticoagulants with minimal bleeding risks. However, the FXIII-A structural features that control its stability and substrate specificity largely remain unknown. Plasma …

Preventing The Violent (Re)Victimization Of Sexual Minority Populations: The Role Of Social Support Networks., Bryan Charles Moore

Electronic Theses and Dissertations

Every year, interpersonal violence affects an important segment of the world population, having deleterious effects on the victims, their families, and societies. Recent scholarship indicates that sexual and gender minority population groups are overrepresented among those who experience or have experienced verbal, psychological, physical, and/or sexual violence. Using an integrative approach, the current study links the past and the present to identify the contextual factors that may increase or decrease the sexual minorities’ risk of violent victimization during adulthood.

Narrative Harmony: The Implementation Of Sound Design And Its Immersive Nature, Patrick Joseph Kelly

Graduate Theses and Dissertations

Sound is the first tool we are given to interact with the world we inhabit. Despite this, most discussion of narrative content revolves around written and visual storytelling. This often means audio is forgotten or overlooked during the production process. A phenomenon which is especially present amongst inexperienced content creators. By combining the transportation imagery model and Narrative Paradigm theories, a formula for analyzing narratives and immersion within the modern setting becomes prevalent. This combination would then lead to the creation of a four-episode podcast series was created where each episode was mixed to highlight a different component in sound …

Automatic Appraisals Of Houses, Sloan Scroggin

Graduate Theses and Dissertations

Multiple hedonic models and an automatic appraiser model were used to create a residential house’s estimated sales price. The goal is to use the limited data available to a REALTOR® to estimate the future sales price of a residential home without the aid of pictures of the property or viewing the physical property. The first model automates some of the actions of an appraiser by finding comparable sales based on proximity, based both on distance between houses and characteristics of the houses, and then calculating a weighted average price for an estimated sales price of future sales. If the model …

Investigations Into The Expansion Of Breslow-Type Intermediate Reactivity Via Radical C-N Bond Homolysis, Jacklyn J. Kubik

Graduate Theses and Dissertations

The Breslow intermediate is a key intermediate in catalytic transformations like the benzoin condensation and Stetter reaction. These intermediates were first postulated by Ronald Breslow in 1958. Since then, a number of researchers have sought to prove their existence and expand upon the reactions possible using these intermediates. In the sixty plus years since this intermediate was first postulated the reaction scope has expanded significantly, Breslow and breslow-type intermediates have expanded to encompass benzothiazoles, imidazoles, benzoimidazoles, triazoles, thiadiazoles, diamino type structures, and most recently pyridine structures. The expansion of these reactions has opened up new avenues of exploration and previously …

Working Alongside People With Disabilities: Their Impact And Value, Alice A. Jensen

Graduate Theses and Dissertations

U.S. policies such as the Workforce Innovation and Opportunity Act of 2014 and the Americans with Disabilities Act support the inclusion of adults with disabilities in all areas of employment. Through WIOA, the federal government required public entities to provide training and help job seekers with disabilities access high-quality, competitive, integrated employment in the labor market. Nevertheless, two-thirds of unemployed PWDs report wanting employment but cannot find a job. Negative perceptions held by employers and hiring managers and their views that PWDs lack abilities create barriers to employment.
