Cortisol And Alpha-Synuclein Stability In Saliva Under Varying Storage And Handling Conditions, Mo Zheng, Sujata Srikanth, Jeremiah Carpenter, Delphine Dean

Journal of the South Carolina Academy of Science

Parkinson’s disease (PD) is a progressive neurodegenerative disorder characterized by motor impairments and non-motor symptoms, significantly impacting patients' quality of life. Currently, cerebrospinal fluid (CSF) is the primary biofluid used for PD biomarker studies, notably α-synuclein, despite the invasive nature of lumbar puncture procedures. Recent work has shown that some of these PD biomarkers have been measured in saliva. As an alternative to CSF, saliva can be non-invasively self-collected by patients repeatedly over time to monitor biomarker levels. However, the stability of these biomarkers in saliva needs to be evaluated before saliva can be considered for patient self-collection studies. Therefore, …

Effect Of Playing Soccer On The Level Of Visual Attention In High School Students, Hamilton Howard

Journal of the South Carolina Academy of Science

Soccer is a great example of a sport that requires a high performing set of cognitive processes. Though it may vary depending on position, each player must be acutely aware of many players on the opposition and friendly sides at once, as well as the ball. This is why soccer players and players of other similarly interactive sports have been found to score higher on executive function tests. However, these tests, especially those for visual attention, are not standardized. Indeed, there seems to be countless ways to test for visual attention, many of which are not considered very objective. The …

Neurosymbolic Cognitive Methods For Enhancing Foundation Model-Based Reasoning, Kaushik Roy, Siyu Wu, Alessandro Oltramari

Faculty Publications

Foundation models have emerged as powerful tools, exhibiting extraordinary performance across various tasks, such as language processing, visual recognition, code generation, and human-centered engagement. However, recent studies have highlighted their limitations when grounded, abstract, and generalized reasoning capabilities are required. Complex tasks often involve multiple hierarchical reasoning steps, which are typical features of human thinking processes. In fact, in this chapter we claim that cognitively-inspired computational models, such as the so-called Common Model of Cognition, are key to enable complex reasoning within foundation model-based artificial intelligence (AI) systems. We investigate neurosymbolic approaches for mapping AI system components to those of …

Striatal Beat Frequency Interval Timing Model With Microgravity Stressor, Jason Michael Fitzgerald, Sorinel Oprisan

Journal of the South Carolina Academy of Science

The Striatal Beat Frequency (SBF) model of interval timing uses frontal cortex (FC) neural oscillations to record the state of the brain at the reinforcement time Tc during fixed interval (FI) procedures in the long-term memory (LMEM). The state of the FC oscillators at any given time is stored in a short-term memory (SMEM) buffer. The SBF model uses the spiny neurons of the basal ganglia (BG) as coincidence detectors to produce beats between the content of the SMEM and LMEM. Across multiple species that can perform interval timing, there are two invariant properties: (a) the timing is precise, and …

Association Between Seated Trunk Control And Cortical Sensorimotor White Matter Brain Changes In Patients With Chronic Low Back Pain, John R. Gilliam, Pradeep K. Sahu, Jennifer M.C. Vendemia, Sheri P. Silfies

Faculty Publications

Trunk control involves integration of sensorimotor information in the brain. Individuals with chronic low back pain (cLBP) have impaired trunk control and show differences in brain structure and function in sensorimotor areas compared with healthy controls (HC). However, the relationship between brain structure and trunk control in this group is not well understood. This cross-sectional study aimed to compare seated trunk control and sensorimotor white matter (WM) structure in people with cLBP and HC and explore relationships between WM properties and trunk control in each group. Thirty-two people with cLBP and 35 HC were tested sitting on an unstable chair …

Achieving Destination Sustainability: How Tourist-To-Tourist Interaction Quality Affects Tourist Loyalty?, Junli Gao, Fang Meng Ph.D., Weifeng Guo, Baomin Lin

Faculty Publications

Although tourist-to-tourist interaction (TTI) has been identified as an essential element in tourist experiences, the effect of TTI quality on tourist loyalty, and the mechanism underlying this effect is scarcely discussed in the literature. Based on the self-determination theory, this study aims to examine whether and how TTI quality influences tourist loyalty, representing a significant means to achieve destination sustainability. More specifically, this study tested a moderated mediation model in which basic psychological needs satisfaction mediated the relationship between TTI quality and tourist loyalty, while sociability moderated the link between TTI quality and basic psychological needs satisfaction. A survey research …

Brain-Hand Function Relationships Based On Level Of Grasp Function In Chronic Left-Hemisphere Stroke, Elizabeth Rizor

Faculty Publications

Background and Objective

The biomarkers of hand function may differ based on level of motor impairment after stroke. The objective of this study was to determine the relationship between resting state functional connectivity (RsFC) and unimanual contralesional hand function after stroke and whether brain-behavior relationships differ based on level of grasp function.

Methods

Sixty-two individuals with chronic, left-hemisphere stroke were separated into three functional levels based on Box and Blocks Test performance with the contralesional hand: Low (moved 0 blocks), Moderate (moved >0% but < 90% of blocks relative to the ipsilesional hand), and High (moved ≥90% of blocks relative to the ipsilesional hand).

Results

RsFC in the ipsilesional and interhemispheric motor networks was reduced in the Low group compared …

A Survey Of Improvisation Activities In Average-Age Beginning Piano Method Series And A Sample Two-Year Improvisation Curriculum, Qiwen Wan

Theses and Dissertations

Throughout music history, improvisation has always been part of piano learning and is a mode of expression for the creation of new music. Current research in music education, such as Dr. Edwin Gordon and others indicates that immersion in music improvisation is crucial in beginning students’ acquisition of music skills. However, recent studies demonstrate a continued lack of improvisation activities in their students’ piano studies that complement current research in music education, and fewer studies reviewed improvisation curricula in average-age piano methods. Therefore, there is a need for a study that examines the current state of the improvisation curriculum in …

The purpose of this action research was to understand the impact of computer-based instructional scaffolding in Desmos on Math 3 high school students’ performance and attitudes toward mathematics. The demand for societal mathematics literacy has increased significantly over the last decade and continues to grow. To achieve this literacy, students must reason, augment, communicate, model, and problem-solve with technology applications; development of these skills requires engagement and support through technology-rich learning opportunities.

Currently, Math 3 students are not performing at the proficient level on state exams and are displaying negative attitudes towards mathematics. Student attitudes and performance in technology enhanced …

Tax Client Goals, Regulatory Pressure, And Professional Decision-Making, Spenser G. Seifert

Theses and Dissertations

Drawing on goal theory, I illuminate how client preferences become internalized goals for tax professionals and how these client goals influence the motivated reasoning and ultimate decision-making of tax professionals. Using this theoretical framework, I then utilize an experiment to explore how the presence of salient situational factors – goal specificity, goal progress, and regulatory pressure – influence tax professionals’ decision-making. The results suggest that, as a result of their roles as both client advocates and CPAs, tax professionals default to non-specific “do your best” goals regardless of client preference specificity. Additionally, I find that increased regulatory pressure may curb …

Examining The Effects Of Physical Education Teacher Behaviors On Actual Motor Competence And The Associations Among Actual Motor Competence, Perceived Motor Competence, Enjoyment In Physical Education, And Physical Activity In Early Childhood, Unjong Lee

Theses and Dissertations

Physical Education (PE) can be considered a black box when the interactions between the teacher and the students are unknown. PE as the black box has been embedded in the process-product paradigm. PE teachers can be critical role models for fostering students’ actual motor competence (AMC) because students can learn from what they observe from teachers’ behaviors. Additionally, AMC, perceived motor competence (PMC), and enjoyment in PE can be potential factors to increase students’ PA in schoolbased setting. Therefore, this dissertation consists of two studies that examine PE teacher behaviors, AMC, PMC, enjoyment in PE, and PA in early childhood …

Long-Range White Matter Fibres And Post-Stroke Verbal And Non-Verbal Cognition, Rebecca W. Roth, Deena Schwen Blackett, Ezequiel Gleichgerrcht, Janina Wilmskoetter, Chris Rorden, Roger Newman-Norlund, Souvik Sen, Julius Fridriksson Ph.D., Natalie Busby, Leonardo Bonilha

Faculty Publications

Among stroke survivors, linguistic and non-linguistic impairments exhibit substantial inter-individual variability. Stroke lesion volume and location do not sufficiently explain outcomes, and the neural mechanisms underlying the severity of aphasia or non-verbal cognitive deficits remain inadequately understood. Converging evidence supports the idea that white matter is particularly susceptible to ischaemic injury, and long-range fibres are commonly associated with verbal and non-verbal function. Here, we investigated the relationship among post-stroke aphasia severity, cognition, and white matter integrity. Eighty-seven individuals in the chronic stage of stroke underwent diffusion MRI and behavioural testing, including language and cognitive measures. We used whole-brain structural connectomes …

Perspectives On Transition To Adult Healthcare For Adults With Williams Syndrome And Their Caregivers, Andrea Johnson

Theses and Dissertations

Transitioning to adult care services is a crucial time for young adults with a genetic condition. Many of these conditions are diagnosed early in childhood, with follow-up care fragmented and dependent on the specific needs of the individual. Williams syndrome (WS) is a complex genetic condition characterized by multisystemic features. The variation in the clinical presentation of adults with WS can influence the individual’s ability to transition from pediatric care because of its medical complications, variable and poorly characterized psychiatric needs, and intellectual disability that causes difficulty communicating health-related needs to providers. This study focused on understanding the needs of …

Mental Trauma, Colonial Mimicry, And Internalized Racism In Tsitsi Dangarembga's The Book Of Not, Lily Kay Lynn Cook

Theses and Dissertations

Tsitsi Dangarembga’s second novel in her Nervous Conditions trilogy, The Book of Not (2006) emphasizes the disabling nature of colonial domination and terror through pain and violence inflicted on the body and the mind. Through the use of Frantz Fanon’s colonial and post-colonial theory and Homi Bhabha’s concept of colonial mimicry the critical nature of Tambudzai—the main protagonist—position in the novel becomes apparent. Just as the title suggests, the novel becomes a book of negation and unbecoming as Tambudzai tries to find her place as a woman in Southern Rhodesia while attending a European colonial institution while war rages just …

Student Experiences With Self-Determination And Agency: Centering Disabled Voices Through Photovoice, Rebecca Boineau Smith Hill

Theses and Dissertations

Young adults with intellectual and developmental disability (IDD) are less likely than young adults without disability to be employed, enrolled in postsecondary education, or live independently after high school (Lauer & Houtenville, 2017; Newman, et al., 2011). Self-determination, or the freedom to act as the primary causal agent in one’s life (Palmer & Wehmeyer, 1998), is a well-documented component of enhanced quality of life (Shogren et al., 2017) and a predictor of postschool success (Mazzotti et al., 2021; Test et al. 2009) for students with disabilities. People with IDD are less self-determined than their nondisabled peers, and often less self-determined …

Unpacking The Relationship Between Legitimacy, Procedural Justice, Identity, And Desistance, Qassim Bolaji

Theses and Dissertations

Knowing why people stop offending over time and the criminal justice agencies' role in this process is essential for designing effective crime control interventions. Legal authorities have the core function of ensuring that social norms and laws are obeyed. However, the coercive and punitive tactics that police, judicial, and penal authorities typically resort to have been shown to have only limited impact on controlling and preventing crime while having the unintended consequence of worsening the public's perception of their institutional legitimacy. Specific to policing, the use of coercive policing tactics and their perceived ineffectiveness has, in recent decades, led to …

Patients’ Experience Of Care Following Perinatal Case Conference, Mary Elise Nolen

Theses and Dissertations

The Perinatal Case Conference (PCC) at Prisma Health-Midlands Maternal-Fetal Medicine (MFM) is a biweekly multidisciplinary meeting to discuss pregnancies with prenatally identified congenital anomalies. Patients are primarily cared for by MFM and may have appointments with various subspecialists during their pregnancy. The goals of the PCC are multidisciplinary collaboration in planning for the management of each pregnancy and familiarizing each practitioner with the pending cases, so if or when intervention is needed, the clinicians are familiar with the case.

Researchers performed a chart review and surveyed patients whose pregnancies were discussed in the PCC to learn the patient’s perspective of …

Perception Of Alzheimer’S Actionability Among End Users Of Direct-To-Consumer Genetic Tests, Emily Mason

Theses and Dissertations

The APOE ε4 allele is the best-known genetic risk factor for developing late-onset Alzheimer’s disease. Although new evidence is emerging, the extent to which lifestyle improvements can reduce Alzheimer’s risk needs further investigation. Research suggests that individuals with a higher genetic risk may be more likely to engage in risk-reducing health behavior changes following results disclosure. This study aimed to better understand these findings by assessing the health behavior and perceptions of Alzheimer’s actionability among consumers of DTC genetic tests. Our study revealed that individuals with 2 copies of the APOE ε4 allele were less likely to make lifestyle modifications …

Maternal-Child Cortisol Attunement Differs In Preschoolers With Autism, Fragile X Syndrome, And Neurotypical Development, Rachel Hantman

Theses and Dissertations

Early maternal-child attunement sets a critical foundation for later social development. While maternal and child cortisol attunement in neurotypical (NT) development has been clearly established, little research has examined these relations in neurodevelopmental populations, such as those with autism spectrum disorder (ASD) and Fragile X Syndrome (FXS). Given their elevated-risk for disrupted maternal-child attunement and given elevated stress and dysregulated cortisol patterns in both children with ASD and FXS and their parents independently, this is a critical gap. This study addressed this gap in the literature by examining early maternal-child cortisol attunement in 97 mother-child dyads (_nNT = …

The Effect Of Voluntarily Disclosing An Earnings Surprise On Management Operating Decisions, Jonathan Gay

Theses and Dissertations

Prior research extensively examines the external implications of voluntarily disclosing an earnings surprise, yet the internal implications remain understudied. Using two experiments, I examine whether the preemptive voluntary disclosure of an earnings surprise influences management operating decisions. Drawing upon mental accounting and the realization effect, I predict that managers are more likely to make inefficient operating decisions when an earnings surprise is expected and that a quantitative, but not qualitative, voluntary disclosure will mitigate this value-sacrificing behavior. I find that managers are more likely to make inefficient operating decisions when a negative, but not a positive, earnings surprise is expected …

The Effect Of Covid-19 Restrictions On The Social Support Experiences Of Black Women Giving Birth In South Carolina Hospitals During The First Year Of The Covid-19 Pandemic (2020) As Compared To A Previous Birth, Tiffany Eva Byrd

Theses and Dissertations

The United States is experiencing a maternal health crisis, which disproportionately affects Black women. Black women die from pregnancy-related causes two to three times as often as their White counter parts, and the majority of maternal death are preventable. In recent years, public health and national governing authorities have devoted resources to monitoring the health crisis and raising the public’s knowledge of warning signs; however, maternal mortality rates continue to rise. Noted contributors to Black maternal mortality include, but are not limited to, racism, delayed treatment and response to health emergencies, and lack of social and emotional support during childbirth, …

Reading Ecogothic Memory In Contemporary Southern Swamp Novels, Megan Caroline Brockhard Knight

Theses and Dissertations

The ecogothic is a lens through which to engage memory, southern constructivism and identity, environmental intervention, and the literature of the American Southeast. This project establishes a framework of literary criticism that defines the ecogothic, interprets memory as truth imagined, and identifies the position of memory in the environment as a construction with which it is necessary to grapple to understand identity. This framework, compiled of existing and original scholarship, is then applied to three contemporary swamp narratives written by three different southern women writers. The swamp setting creates a unique microcosm of gothic liminality, neither fully land nor water, …
