Tailored Multifunctional Heterometallic Metal-Organic Frameworks, Otega Anthonia Ejegbavwo

Theses and Dissertations

Metal-organic frameworks (MOFs), which are well-defined and porous extended structures consisting of organic linkers connected to inorganic secondary building units, are a class of materials that have received tremendous attention over the last decade. This geometrically growing interest in MOFs is attributed to their properties of porosity, tunability, modularity, crystallinity, flexibility, and long-term stability, which makes them attractive candidates for various applications. This dissertation focuses on two major studies, the first part encompasses the strategic design, preparation, and extensive studies of actinide containing MOFs (An-MOFs). This work, presented within the first two chapters, demonstrates the effective utilization of MOF modularity …

Flexible Regression Models For Survival Data, Ennan Gu

Theses and Dissertations

Survival analysis is a branch of statistics to analyze the time-to-event data or survival data. One important feature of survival data is censoring, which means that not all the subjects’ survival time are observed directly. Among all the survival data, right-censored data are the most common type and consist of some exactly observed survival times and some right-censored observations. In this dissertation, we focus on studying flexible regression models for complicated right-censored survival data when the classical proportional hazards (PH) assumption is not satisfied. Flexible semiparametric regression models can largely avoid misspecification of parametric distributions and thus provide more modeling …

Examining Biobehavioral Indicators Of Adhd In Children With Fxs, Hannah Pressler

Senior Theses

Attention-deficit/hyperactivity disorder (ADHD) is a neurodevelopmental disorder characterized by inattention and hyperactivity/impulsivity behaviors that are inconsistent with developmental age. Children with fragile X syndrome (FXS), a genetic neurodevelopmental disorder, are often diagnosed with comorbid ADHD (53-59% of males with FXS). Despite the prevalence of ADHD in FXS, little is known about the early manifestation of ADHD. The current project aims to explore group differences in play behaviors between children with FXS and typically developing (TD) children as well as the correlation of infant play behavior and heart activity to future ADHD attention outcomes. Participants included male children with FXS and …

Dr. Julius Hallervorden’S Role In Nazi “Euthanasia”, Kylee Yturralde

University Libraries Award for Undergraduate Research

On the path to becoming a doctor, many undergraduate students focus their studies exclusively on STEM classes. This prepares students well for medical school but disregards the significance of Humanities courses that are imperative to becoming ethical physicians who can relate and advocate for those around them. I spent the last one and a half years investigating Dr. Julius Hallervorden, a famous 20th century neuropathologist, who became complicit in criminal acts perpetrated in the Nazi “euthanasia” program. Dr. Hallervorden was not tried in the Nuremberg Doctors’ Trial. Prosecutors determined there was insufficient evidence to convict him of murdering patients. After …

First Aid And Emergency Preparedness: Improving Health Outcomes Among Aging Adults, Anna J. Kulangara

Senior Theses

As the United States population demographic shifts and the baby boomer population enters seniority, the health sector must adjust and prepare to provide efficient and adequate healthcare to the people. The Silver Tsunami, a metaphor for the expected wave of aging adults, will inevitably strain healthcare professionals and can be partly relieved by promoting risk-minimizing behavior in baby boomers before severe conditions develop. Through this effort, a health education course, titled First Aid and Emergency Preparedness, was developed and taught twice at a local senior center to target senior citizens and promote proactivity and healthy behaviors. Course development founded largely …

Investigating The Effects Of Aggregate Size And Reinforcement On Asr Cracking In Concrete Structures Studied With Different Evaluation Methods, David Joseph Bianco

Theses and Dissertations

The objective of this thesis is to investigate different (non-destructive) evaluation methods to assess the effects of reactive aggregate size and reinforcement on ASR affected concrete. It has been shown in previous literature that reactive coarse aggregates lead to more expansion as opposed to reactive fine aggregates. However, there is a lack in the literature exhibiting this relationship using different evaluation methods, such as acoustic emission (AE) and ultrasonic pulse velocity (UPV). Also, the literature does not emphasize the role this relationship plays when the concrete is imposed with stress boundary conditions. Non-destructive test methods, including acoustic emission, are becoming …

The Cultural Relevance Of Music Education As It Relates To African American Students In South Carolina, Felicia Denise Denise Myers Bulgozdy

Theses and Dissertations

In this study, Critical Race Theory is used to examine the current curriculum that preservice music teachers are taught, and are consequently teaching K-12 students, in an effort to illustrate the need for Culturally Relevant Pedagogy. Documents such as the S.C. All-State Choral rubric, as well as a list of required courses for future music educators at a local university, are studied to show the overwhelming European influence on the curriculum that is being taught in music classes daily across the state, and demonstrate the lack of cultural relevance to the African American students in those classes. Culturally Relevant Pedagogy …

The Role Of Acute And Chronic Neuroinflammation In Depression: Uncovering The Relationship Between Histamine And Serotonin Transmission, Melinda Hersey

Theses and Dissertations

Depression is the leading cause of disability worldwide. Disorders of the brain, including depression, are notoriously difficult to treat because the basic pathology underlying behavioral outcomes remains undefined. Robust chemical biomarkers of these diseases have not been identified, nor are there reliable methods to measure brain chemicals. Depression is associated with chemical and inflammatory changes in the brain that are predicted to contribute to the pathology. By studying the serotonin and histamine systems we aim to better define the neurochemical basis of depression. Serotonin has long been hypothesized to play a role in depression since selective serotonin reuptake inhibitors (SSRIs) …

Integrating Survivors Of Stroke Into Cardiac Rehabilitation, Elizabeth Wherley Regan

Theses and Dissertations

Stroke is the leading cause of disability in the United States (U.S.). Impairments after stroke typically result in reduced physical activity which increases the risk for stroke recurrence and the development or worsening of comorbid health conditions. Physical activity and exercise behaviors can reduce cardiovascular risk factors and improve endurance for survivors of stroke. Despite these known significant benefits, survivors of stroke face barriers to participating in regular physical activity due to limited self-efficacy, safety concerns, environmental restrictions and lack of accessible community programs.

Cardiac Rehabilitation (CR) is a structured exercise and behavior modification program for people with cardiovascular disease …

Unpacking The Effects Of International Experience In Intercultural Negotiations, Chei Hwee Chua

Theses and Dissertations

This dissertation examines how international experience influences the outcomes of intercultural negotiations. Its main contributions lie in the novel and contextualized conceptualization of international experience and the development of a comprehensive theoretical model that unpacks the effects of international experience in intercultural negotiations. I propose that international experience is a multi-dimensional construct that encompasses four dimensions: breadth, depth, cultural distance, and cultural heterogeneity. I argue that experiences abroad develop and strengthen individuals’ intercultural competence, psychological capital and global identity, which in turn positively influence the outcomes of intercultural negotiations, i.e., they mediate the relationship between international experience and intercultural negotiation …

Gendering Secession: Women And Politics In South Carolina, 1859- 1861, Melissa Develvis

Theses and Dissertations

This dissertation examines the writings and literature surrounding elite, white South Carolina women from 1859 and 1861 to trace their increasing political consciousnesses surrounding their state’s secession and the threat of civil war. Their diaries and letters reveal that though these women and their families were staunch supporters of South Carolina’s secession, women reacted to their new circumstances with fears and misgivings that their male counterparts would not, or could not, express. Elite women harnessed familiar and religious concepts to express political hopes and fears, creating a socially acceptable outlet through which to discuss current electoral politics previously considered improper. …

Swept Away Before Learning To Swim: Social Studies Subject Area Literacy For High School Students, Aaron K. Shaw

Theses and Dissertations

History education provides a valuable asset in the education of youth from the integration of disciplines to the opportunity to stimulate higher order thinking in high school students. However, little research before the 1990’s had been done to improve the century old pedagogy of presentation and memorization. This study looked at the historical thinking skills of sourcing, contextualization and corroboration, presented in Sam Wineburg’s (1991b) research comparing high school students with professional historians. This mixed methods study explored the impact of focused instruction in high school social studies classrooms using the three historical thinking skills to determine the effectiveness …

The costume design and technology program at the University of South Carolina demands that students learn each facet of the profession extensively. The highlights and most growth-inducing experiences for me were the opportunities to design costumes for four main stage productions. I gained an understanding of costume-based research, watercolor and digital rendering, building ideas with a director, working out a cohesive look with other designers, and communicating about garment construction with a costume shop. I also built up my costume construction skills and learned to flat pattern and drape. With opportunities to work professionally, I honed my shop management and …

The Utility Of Whole Exome Sequencing In Patients With Intellectual Disability And Developmental Delay As A First-Tier Diagnostic Testing Strategy, Ellen Richardson

Theses and Dissertations

The purpose of this study is to evaluate the diagnostic utility of whole exome sequencing (WES) in patients with intellectual disability (ID) or developmental delay (DD), and to determine which patients may be the best candidates for WES as a first-tier diagnostic test. The diagnostic and clinical utility of WES has emerged to be greater than that of karyotype and chromosomal microarray for patients with ID or DD of unknown etiology, which are currently recommended as first-tier diagnostic tests for these patients. The emergence of next generation sequencing has led to more rapid identification of rare and novel genetic disorders. …

Ego Sum, Victoria Romero

Theses and Dissertations

The use of first-person narration in literature has traditionally been used to impart a sense of intimacy, immediacy, and relatability between the reader and the work’s narrator. First-person narration has also traditionally acted as an initial step in crafting a signature voice or style for fiction writers in creative writing—one that is often abandoned as the writer’s style matures. Additionally, the cultural climate of this and preceding years has engendered many debates and discussions centering on which voices are heard and received as credible witnesses to political, institutional, and social events. The MeToo Movement, Supreme Court Justice Kavanaugh’s confirmation hearings, …

Are You A Boy Or A Girl?: Representations Of Transgender Children In Picture Books, Joshua Hill

Theses and Dissertations

This research was a critical content analysis of picture books that contained transgender children utilizing Butler’s (2004, 2006) performativity of gender and recognizability of gender alongside Engdahls’s (2014) wrong-body discourse. The question was, how do picture books about transgender represent various versions of queerness in children? This analysis was done by examining 20 total picture books which included 10 books about trans girls, six books about trans boys, and four books about nonbinary children. These 20 books were then broken down into eight books for a deeper analysis of the ways that queerness was represented. The findings included the ways …
