Adapting North American Fiddle Bow Technique To The Double Bass, Spencer Jensen

Theses and Dissertations

Because of the pioneering work of Edgar Meyer in expanding the role of the double bass in American folk music, many bassists are inspired to engage with fiddle music in the way fiddlers do. Thus, bassists who perform in fiddle and string band traditions may seek greater artistic freedom and expression by shifting between a variety of accompanying textures to playing melody and improvised bowed solos.

In seeking to discover how bassists successfully adapt fiddle bowing techniques to the double bass, I have interviewed two bassists who are deeply involved in Americana music traditions, Paul Kowert and Ethan Jodziewicz. From …

Perceptions Of Gifted Male Underperformance, Laura Bryant Palmer

Theses and Dissertations

The underperformance of gifted students is a concern facing all educators. Having students who do not work up to their potential, who make grades lower than test scores show they could, and who choose to focus on other interests instead of academics are issues that occur in many schools. This study sought to learn the perceptions of educational leader in regard to this underperformance. The Palmer Model, a proposed intervention plan, was developed based on a Response to Intervention (RtI) model using a 3-tier intervention approach. Using online questionnaires and focus groups, perceptions were examined and critiques of the proposed …

The Most Important Human Capital Resource: A Strategic Human Resources Perspective On Top Management Team Effectiveness, Spenser Michael Essman

Theses and Dissertations

This dissertation comprises two studies that theoretically and empirically examine a critical human capital resource, the top management team (TMT). In the first chapter, I propose a conceptual model that focuses on the context in which TMTs are embedded, by building on recent theory suggesting that the TMT is embedded within a multiteam system, referred to as a strategic leadership system. Specifically, I suggest that functional leadership teams – decision making groups responsible for managing firm functions and business units (e.g. finance; human resources) – are likely to be a part of the strategic leadership system, and develop theory regarding …

Integrated Behavioral Health And Primary Care: Refining A Determinant Framework, Ariel Michelle Domlyn

Theses and Dissertations

The integration of behavioral health and primary care is a best practice to improve patient outcomes and achieve health equity. However, the process of integrating is opaque, requiring organizational change and sometimes a complete system overhaul. Implementation science offers useful ideas for helping healthcare organizations to implement care. This field has identified potential environmental conditions and determinants of successful implementation; however, much is still unknown about how these factors may be relevant for organizations seeking to integrate care. To address the limited existing knowledge in this area, this dissertation gathers practice-based evidence using exploratory methods. Results are translated into an …

Meaningful And Interactive Learning Experiences Provided Through A Learning Management System: An Action Research Study In Ninth Grade Advanced Placement Human Geography, Daniel Robert Plonski

Theses and Dissertations

The purpose of this mixed methods action research was to determine if increased interactive Schoology-based modules could alter learner perceptions concerning the lack of meaningful learning (learner-instructor, learner-learner, learner-content) in the culture unit of instruction in an Advanced Placement Human Geography (APHG) classroom. A series of instructional modules were facilitated through the learning management system (LMS) Schoology to students (n = 16) in APHG at a southeastern U.S. high school. The interactions were designed to enhance interaction based upon the criteria provided by Piaget’s (1981) social constructivist theory, specifically Moore and Kearsley’s (2011) systems approach and Miyazoe and Anderson’s (2010) …

Afro-Diasporic Literatures Of The United States And Brazil: Imaginaries, Counter-Narratives, And Black Feminism In The Americas, David E. S. Beek

Theses and Dissertations

This dissertation explores contemporary Afro-diasporic literatures by black cultural producers in the United States and Brazil that resist, subvert, and dismantle the persistent myth of Brazilian racial democracy. From the US, I investigate John Keene’s 2015 collection of stories and novellas Counternarratives, in addition to Gayl Jones’ 2021 novel Palmares. Conversely, from Brazil, I examine Conceição Evaristo’s 2003 novel Ponciá Vicêncio, as well as the black trans musician and slam poet Bixarte’s social media performance art. Although these Afro-diasporic literatures deconstruct the myth of racial democracy in Brazil, at the same time, each is entangled with what …

Methodological Mutability: Shifting Research In The Rhetoric Of Health And Medicine, John Schuler Benson Iii

Theses and Dissertations

The Rhetoric of Health and Medicine (RHM) is a growing body of scholarship that pulls from technical communication, rhetorical theory, and a number of other disciplines to inquire about the capacities of rhetoric at the intersection of medical practitioners and scholars, the medical humanities, and the publics they inform and treat. Among RHM scholars there is a consensus that the field’s methodological diversity is one of its greatest strengths; indeed, field leaders articulate one of RHM’s exigencies as “encouraging methodological collaboration and experimentation” (Melonçon and Scott, Methodologies 4). This dissertation takes up these calls with the introduction of shifting, a …

Role Of Epigenome In Regulation Of Inflammation By Ahr Ligands 2,3,7,8-Tetrachlorodibenzo-P-Dioxin And 6-Formylindolo[3,2-B] Carbazole, Alkeiver Cannon

Theses and Dissertations

Autoimmune Hepatitis (AIH) is a chronic inflammatory disease of the liver mediated by immune cells and characterized by a variety of parameters including circulating autoantigens, elevated immunoglobulin G (IgG) and aminotransferases, and interface hepatitis. Unfortunately, despite treatment with broadly immunosuppressive drugs, the disease progresses to cirrhosis and end-stage liver disease in several cases. In order to develop a more specific treatment, the mechanisms governing the liver injury resulting from inflammation and autoimmunity need to be elucidated.

For decades, activation of Aryl Hydrocarbon Receptor (AhR) was excluded from consideration as a therapeutic approach due to the potential toxic effects of AhR …

The Development Of A Monolithic Spatial Heterodyne Spectrometer For Extreme Environments, Arelis Michelle Colόn

Theses and Dissertations

This work describes improvements to a novel instrument, the monolithic spatial heterodyne Raman spectrometer (mSHRS), which has potential to be utilized in space exploration and deep-ocean marine sensing. In previous work, the spatial heterodyne Raman spectrometer (SHRS) was demonstrated, as a small, high resolution, wide field of view spectrometer, originally developed for space applications where small size and compactness is a key consideration or where a wide field of view is advantageous, such as in remote spectroscopy. The spatial heterodyne spectrometer (SHS) was then later utilized for remote Laser-Induced Breakdown Spectroscopy (LIBS). The high throughput, high spectral resolution, and large …

Place Identity And Gentrification-Induced Social And Cultural Displacement Among Longstanding Black American Residents: Theory, Case, And Innovating Methodology, Brittany B. Davis

Theses and Dissertations

Scholars have increasingly recognized the sociocultural impacts of gentrification on Black residents. However, the gentrification literature lacks an empirically tested theoretical model on the nuanced ways gentrification may socially and culturally displace longstanding Black residents. Limited attention has also been given to factors that may moderate social and cultural displacement. Since place identity (i.e., one’s sense of belonging to a place) encompasses residents’ social and cultural connections to their neighborhoods, conceptualizing social and cultural displacement in relation to place identity helps to understand a potential moderating factor. Furthermore, although space and place dynamics of gentrification have been well-documented, gentrification research …

Evaluation Of Monthly And Seasonal Grazing Rates Of Ilyanassa Obsoleta On Benthic Microalgae In The North Inlet Estuary, Brittany Dearmitt

Theses and Dissertations

The eastern mud snail, Ilyanassa obsoleta, is found at densities of 100’s of individuals m^-2 on soft sediments in the intertidal zones of estuaries. These obligate deposit feeders consume microalgae, detritus, larvae, meiofauna, and macrofauna in the surface layers of sediments with possible trophic impacts on benthic microalgal (BMA) biomass. The goals of this study were to quantify mud snail grazing on BMA biomass, observe the variation in monthly and seasonal grazing rates, and evaluate the relationship between atmospheric temperatures and grazing rates. The sites for this experiment were two mudflats in Oyster Landing, North Inlet estuary, South …

A Novel Cognitive Stress Paradigm To Assess Subtle Cognitive Differences In Women With The Fmr1 Premutation, Jillian Margaret Gierman

Theses and Dissertations

Fragile X premutation (FXPM) is a genetic mutation of the FMR1 gene characterized by having between 55-200 CGG repetitions. FXPM women are at risk for a variety of reproductive, cognitive, and neuropsychiatric deficits, including fragile X-associated primary ovarian insufficiency (FXPOI) and fragile X-associated tremor/ataxia syndrome (FXTAS). FXTAS is a late-onset neurodegenerative disorder characterized by tremor, gait ataxia, cognitive decline, brain atrophy, and deficits in executive functions. With the evidence supporting premature aging, prevalence of cognitive deficits, and risk of developing FXTAS and dementia, it is imperative to find a reliable measure that identifies at-risk FXPM women and their subtle cognitive …

Unintended Consequences Of The Electronic Health Record And Cognitive Load In Emergency Department Nurses, Carolyn S. Harmon

Theses and Dissertations

Background: The electronic health record (EHR) was rapidly implemented to improve patient safety. However, this rapid and widespread EHR implementation negatively connects to patient safety. Clinician cognitive overload is also thought to be negatively connected to patient safety, especially in the chaotic emergency department (ED) setting. Limited research has been conducted on unintended consequences of the EHR (UC-EHR) and cognitive load (CL) in ED nurses. Understanding the UC-EHR and CL in ED nurses facilitate informed interventions to improve nursing practice and patient safety.

Aims: Guided by the Systems Engineering Initiative for Patient Safety (SEIPS) 2.0 framework, the aims of this …

Sensory Processing In Male Children With Fragile X Syndrome And Idiopathic Autism: Implications For Maladaptive Behavior And Within-Syndrome Heterogeneity, Chandler Knott

Theses and Dissertations

Proficient sensory processing affords adaptive responses that are necessary for daily functioning. Atypical sensory processing patterns are common across neurodevelopmental disorders, including autism spectrum disorder (ASD) and fragile X syndrome (FXS), two disorders with a high degree of phenotypic overlap. However, little is known about whether types of atypical sensory processing in FXS vary as a function of genetic etiology or the presence of ASD. Atypical sensory processing has been also associated with maladaptive outcomes in certain clinical populations; however, the impact of these impairments on internalizing and externalizing behavior remains unknown in FXS. Study participants included 37 male children …

Subject Cognitive Decline In Informal Caregivers, Eunika Simons

Theses and Dissertations

Purpose. The United States is experiencing unprecedented demographic shifts as the population continues to age. More than 53 million Americans are caregivers and that number is continuing to grow. Caregiving has become a significant societal and public health issue to be addressed. This study provided a population-based national perspective regarding informal caregivers to identify differences between caregivers reporting cognitive decline and those caregivers reporting no cognitive decline. The analysis explored the relationships between the type and characteristics of informal caregivers, the nature of the caregiving relationship, caregiver unmet needs, and the general, physical, and mental health-related outcomes of the caregivers. …

Mechanisms Of Connectivity In Neuronal Development, Janay Vacharasin

Theses and Dissertations

The development of neuronal connectivity requires the careful orchestration of multiple cellular processes including the control of neuronal arborization and synapse formation or function. Defects in these processes during neuronal development will give rise to disorders of neuronal connectivity like autism. In the present work, we examine the genetic and epigenetic mechanisms that build the neuronal wiring of the developing brain. We use human stem cell-derived neurons to study neuronal arborization and function focusing on genetic and environmental risk factors of neurodevelopmental disorders that include autism and intellectual disability. Specifically, we focused on the contribution of the endomembrane, chromatin, and …

Impact Of The Resident Mentor Role On Student Worker Mental Health, Lauren Cartwright

Senior Theses

What do stress and burnout look like for RMs at a flagship university in the southeast during the early Covid-19 epidemic? How would the average student worker rate the RM role in terms of satisfaction, recommending the role to others, and weekly workload?

To answer these questions, I surveyed 51 Resident Mentors (RM) at the University of South Carolina (UofSC) in Spring, 2021 to gather information on their general backgrounds, workload, and overall satisfaction with the RM role. Results generally showed high workloads and stress levels. I argue that these findings may be reflective of role ambiguity and changes in …

Transcranial Alternating Current Stimulation As An Adjuvant For Nonfluent Aphasia Therapy: A Proof-Of-Concept Study, Lynsey Mcgrath Keator

Theses and Dissertations

Identifying effective and efficient rehabilitation tools is crucial to improve language outcomes for persons living with chronic aphasia. Speech entrainment has proved to be particularly successful in improving speech output in nonfluent aphasia. It is hypothesized that, for patients with aberrant oscillatory synchronization between anterior and posterior language regions of the left hemisphere, speech entrainment may act as an external gaiting mechanism to bolster an impaired efference copy and improve synchrony between these regions. Theoretical and empirical evidence supports this idea that speech production relies on anterior-posterior connectivity in the left hemisphere.

Transcranial alternating current stimulation (tACS) delivers low, periodically-alternating …

Automated Contingency Management For Water Recycling System, Shijie Tang

Theses and Dissertations

NASA’s exploration program envisions the utilization of a Deep Space Habitat (DSH) for human exploration of the space environment in the vicinity of Mars and beyond. Communication latency and extreme limitations of power and life-supporting resources make it imperative to operate the DSH systems in a highly autonomous fashion. One such system is the Environmental Control and Life Support System (ECLSS) which needs to be monitored and optimized to support its designated missions.

Inhibitory Control Of Emotional Interference In Deaf Children: Evidence From Event-Related Potentials And Event-Related Spectral Perturbation Analysis, Qiong Chen, Junfeng Zhao, Huang Gu, Xiaoming Li Ph.D.

Faculty Publications

Background: Impairment of interference control ability may reflect a more general deficit in executive functioning, and lead to an increase in internal-externalized problems such as impulsivity, which has been reported in deaf children. However, few researches have examined the neural mechanism of this impairment.

Methods: This study applied the electroencephalogram (EEG) technique to investigate the interference control ability in 31 deaf children and 28 hearing controls with emotional face-word stroop task.

Results: Results from behavioral task showed that deaf children exhibited lower accuracy compared to hearing controls. As for EEG analysis, reduced activation of ERP components in N1 and enhanced …

Ideology And Anti-Ideology In Painting: ‎ The Case Of Gerhard Richter And Luc Tuymans, Efrat Biberman

Journal of Ideology

This paper explores two cases of complex relationship between painting an ideology. These two cases will serve to outline the intricate relation between painting and ideology. Besides, they will also make it possible to understand, in a slightly different manner, the visual aspect of the very concept of ideology or worldview and the unique fashion in which this concept may be realized in painting.

Before analyzing these cases, I examine the psychoanalytic conceptualization of ideology in general, and not necessarily in its relation to art, as designated by Freud and Lacan. As I will later show, while psychoanalysis criticizes ideological …

Does Hiv-Related Stigma Depress Social Well-Being Of Youths Affected By Parental Hiv/Aids?, Yafei Zhao, Jiaojiao Wan, Lili Ji, Giagai Lui, Yixin Shi, Junfeng Zhao, Xiaoming Li Ph.D.

Can Language Models Capture Graph Semantics? From Graphs To Language Model And Vice-Versa, Tarun Garg, Kaushik Roy, Amit Sheth

Publications

Knowledge Graphs are a great resource to capture semantic knowledge in terms of entities and relationships between the entities. However, current deep learning models takes as input distributed representations or vectors. Thus, the graph is compressed in a vectorized representation. We conduct a study to examine if the deep learning model can compress a graph and then output the same graph with most of the semantics intact. Our experiments show that Transformer models are not able to express the full semantics of the input knowledge graph. We find that this is due to the disparity between the directed, relationship and …
