Teaching About Transfer: Making The Invisible Visible Through Explicit Instruction, Brittany Morgan Capps

Theses and Dissertations

Transfer of learning—or the act of adapting previously learned knowledge to new contexts—is an inherently complex process made even more mystifying by its often unconscious and therefore “invisible” occurrence. Writing, too, is a complicated activity that depends on and responds to a number of internal and external factors. Transferring writing knowledge, then, is a challenging task for writers of all experience levels. Researchers in writing studies have designed curricula intended to help college students transfer writing skills, knowledge, and practices from the writing classroom to other disciplinary and workplace contexts. Those teaching for transfer (TFT) and writing about writing (WAW) …

An Examination Of Sustained Attention During Complex Multitasking Scenarios, Jonathan Cheshire Rann

Theses and Dissertations

This dissertation project examined the time-course of vigilance decrements that occur when operators perform demanding multitasking activities. For this aim, we conducted three experiments which implemented a novel paradigm we developed that measured performance during two sessions: a Single-Task session in which participants performed a go-no-go target detection task in the absence of any other task for approximately 12 minutes; and a Multi-Task session in which participants performed the detection task simultaneously with a driving-based tracking task for the same duration. A total of 183 participants from the University of South Carolina Department of Psychology took part in this study. …

The Emergence And Predictive Utility Of Early Markers Of Social Anxiety In Young Children With Fragile X Syndrome, Conner James Black

Theses and Dissertations

Fragile X syndrome (FXS) is a monogenic neurodevelopmental disorder characterized by elevated rates of intellectual disability, autism, and anxiety. Social anxiety affects approximately 60 percent of individuals with FXS and is cited as one of the most impairing comorbid disorders in FXS; however, little is understood about the developmental patterns of social anxiety markers in young children with FXS. The current study investigates cardiac and behavioral markers of social anxiety across the first five years of life and tests the predictive utility of these variables on social anxiety symptomatology. Participants included 80 children with FXS and 50 neurotypical controls. Participants …

Colored Lawyer, Topeka: The Legend And Legacy Of Elisa Scott, Jeffery Scott Williams

Theses and Dissertations

Attorney Elisha Scott’s reputation for fighting injustice grew so large he received letters addressed only, “Colored Lawyer, Topeka, Kansas.” He was born in obscurity in 1890, but his death made national news in 1963. Scott’s story may not be known at all if his name was not often listed as counsel in Brown v. Board of Education, the 1954 case that desegregated public schools. But it was his sons who filed the case and helped fight it from Topeka to the United States Supreme Court. He was never officially part of the legal team. He had, however, won a …

A second phase of professional development occurred using a Community of Practice model. Phase-two findings showed conceptual teaching practices …

Examining Recommended Strategies For Accommodating Negatively Worded Items, Jungsun Go

Theses and Dissertations

The purpose of this study was to investigate the effectiveness of four different models (bifactor, CTC(M-1), CTCU and unidimensional) as to optimal model selection when the wording effect associated with negatively worded items was present. A Monte Carlo simulation study was conducted to compare model-data fit and accuracy in parameter estimates of the four models. Design factors include: two true models (CTC(M-1), CTCU models) × three sample sizes (small N=250, moderate N=500, large N=1,000) × two item ratios (positive items:negative items = 2:1 or 1:1) × three distributions (distribution of negative items; symmetric, moderately asymmetric, and extremely asymmetric). The generated …

Hf Radar: Shining A Light On Ocean Currents, Douglas Cahl

Theses and Dissertations

High Frequency (HF) radar systems are commonly used to estimate surface ocean currents over the coastal ocean. Their range depends on their operational frequency and low frequency systems (≤ 10 MHz) can reach distances up to 200 km from the coastline. These systems are used to estimate surface currents by measuring the phase speed of wind-driven waves and comparing the measured speed with that expected theoretically; deviations from the theoretical still-water phase speed are attributed to ocean surface currents. Although HF radar systems are considered a mature technology and the accuracy of the radar-derived surface current estimates is well studied, …

From Roland To Gawain, Or The Origin Of Personified Knights, Clyde Tilson

Theses and Dissertations

Though there is a lot of work on the development of the novel, there has not been sufficient analysis of how it was formed, especially the shift towards the modern protagonist. By analyzing two medieval works, one from the early medieval period and one from the middle of the medieval period, the seeds of this shift can be seen. The works chosen were La chanson de Roland and Sir Gawain and the Green Knight as both have knights with fairly similar expectations, and both have been enduring characters in their respective national identities and literatures. Both Roland and Gawain, being …

Measurement Of The Total Cross-Section Of Muon Neutrino Charged-Current Coherent Pion Production In Nova Near Detector, Kuruppumullage Don Chatura Dilshan Kuruppu

Theses and Dissertations

Charged Current (CC) coherent neutrino-nucleus pion production is characterized by small momentum transferred to the nucleus, which is left in its ground state. Despite the relatively large uncertainties on the production cross-section, coherent production of mesons by neutrinos represents an important process, as it can shed light on the structure of the weak current and can also constitute a potential source of background for modern neutrino oscillation experiments and searches for Beyond Standard Model (BSM) physics. This Ph.D. thesis presents a new measurement of CC coherent pion production in the NOvA near detector at the Fermi National Accelerator Laboratory (Fermilab). …

Framing Police Brutality: An Analysis Of Newspaper Coverage Of Walter Scott’S Murder, Shamira S. Mccray

Theses and Dissertations

This research analyzes news articles about the killing of Walter Scott in 2015 to determine how frames changed over time and across platforms. Previous studies have found that news coverage of police violence against Black men has not always been fair. Instead, the narrative of official sources, like law enforcement, prove dominant. These same research articles typically focus on the way national news outlets frame incidents like Scott’s.

But this thesis takes a deeper look at how state newspapers framed Scott’s murder. I analyzed the frames and sources found in nearly 200 articles published by The Post and Courier and …

Theses and Dissertations

Student success and achievement can be measured in myriad ways; however, the impact of teacher effectiveness in each classroom is an essential part of the formula for student success. Although most teachers work in isolation in their classrooms, it is important for school leaders to support student success by finding effective methods of supporting teachers. This study investigates the instructional coaching of novice teachers as a professional development tool to support student success and achievement. The specific aim of this study was to investigate if an intervention of instructional coaching was effective in supporting the development of equitable and effective …

Feasibility Of A Parent-Focused, Stress Management Intervention To Decrease Adolescent Bmi, Reduce Stress, And Increase Well-Being Among African American Families, Colby J. Kipp

Theses and Dissertations

African American adolescents in the United States experience a higher prevalence of obesity as compared to their White counterparts. This health inequity presents a public health concern as consequences of weight-related chronic diseases often persist into adulthood and are increasingly problematic. As chronic stress has been found to be higher among African American youth compared to White adolescents, it presents as a potential barrier to participation for African American families in health promotion interventions. Additionally, it may be beneficial to target stress in health promotion programs as a modifiable factor in conjunction with health behaviors that may improve outcomes related …

Neural Mechanisms Of Lexical Semantics: Investigating The Roles Of Hubs And Distributed Action-Perception Systems, Nicholas Andrew Riccardi

Theses and Dissertations

Understanding the meaning of words and concepts is vital for communication, forming relationships, and navigating everyday life. Loss of this knowledge through brain damage can have drastic consequences for one’s health and well-being. It is therefore important to learn how this information is organized anatomically in the brain. In this dissertation, I report a series of structural and functional neuroimaging studies in healthy adults and survivors of stroke seeking to understand how lexical semantics are represented. Specifically, I used a variety of tasks to examine the contributions of putative ‘hubs’ and distributed action-perception systems. Results indicated that damage or disruption …

Marine Anoxia Initiates Giant Sulfur-Bacteria Mat Proliferation And Associated Changes In Benthic Nitrogen, Sulfur, And Iron Cycling In The Santa Barbara Basin, California Borderland, David J. Yousavich, De'marcus Robinson, Xuefeng Peng, Sebastian J.E. Krause, Frank Wenzhoefer, Felix Janßen, Na Liu, Jonathan Tarn, Frank Kinnaman, David L. Valentine, Tina Treude

Faculty Publications

The Santa Barbara Basin naturally experiences transient deoxygenation due to its unique geological setting in the southern California Borderland and seasonal changes in ocean currents. Long-term measurements of the basin showed that anoxic events and subsequent nitrate exhaustion in the bottom waters have been occurring more frequently and lasting longer over the past decade. One characteristic of the Santa Barbara Basin is the seasonal development of extensive mats of benthic nitrate-reducing sulfur-oxidizing bacteria, which are found at the sediment–water interface when the basin's bottom waters reach anoxia but still provide some nitrate. To assess the mat's impact on the benthic …

Model-Driven Analysis Of Ecg Using Reinforcement Learning, Christian O'Reilly, Sai Durga Rithvik Oruganti, Deepa Tilwani, Jessica Bradshaw

Publications

Modeling is essential to better understand the generative mechanisms responsible for experimental observations gathered from complex systems. In this work, we are using such an approach to analyze the electrocardiogram (ECG). We present a systematic framework to decompose ECG signals into sums of overlapping lognormal components. We use reinforcement learning to train a deep neural network to estimate the modeling parameters from an ECG recorded in babies from 1 to 24 months of age. We demonstrate this model-driven approach by showing how the extracted parameters vary with age. From the 751,510 PQRST complexes modeled, 82.7% provided a signal-to-noise ratio that …

Perturbative Aspects Of Cpt-Even Lorentz-Violating Scalar Chromodynamics, Brett Altschul, L. C.T. Brito, J. C.C. Felipe, S. Karki, A. C. Lehum, A. Yu Petrov

Faculty Publications

In this work, we formulate the theory of Lorentz-violating scalar quantum chromodynamics with an arbitrary non-Abelian gauge group. This theory belongs to the class of models encompassed by the standard model extension framework. At the lowest order in the theory's Lorentz violation parameters, we calculate the divergent quantum corrections, including the renormalization group β-functions of the theory. The Lorentz-violating sector is shown to be scale invariant if there is a particular relation between the couplings.

Issue Of Data Imbalance On Low Birthweight Baby Outcomes Prediction And Associated Risk Factors Identification: Establishment Of Benchmarking Key Machine Learning Models With Data Rebalancing Strategies, Yang Ren, Dezhi Wu, Yan Tong, Ana Lopéz-De Fede, Sarah Gareau

Publications

Background: Low birthweight (LBW) is a leading cause of neonatal mortality in the United States and a major causative factor of adverse health effects in newborns. Identifying high-risk patients early in prenatal care is crucial to preventing adverse outcomes. Previous studies have proposed various machine learning (ML) models for LBW prediction task, but they were limited by small and imbalanced data sets. Some authors attempted to address this through different data rebalancing methods. However, most of their reported performances did not reflect the models’ actual performance in real-life scenarios. To date, few studies have successfully benchmarked the performance of ML …

BACKGROUND: The Framingham 10-year cardiovascular disease risk score, which is based on age, sex, smoking, total cholesterol, high-density lipoprotein-cholesterol, blood pressure, and diabetes, has been found to be associated with cognitive health, but these findings have not been validated in a representative sample in the United States. We aimed to examine the associations of Framingham risk score with cognitive function among older adults in a nationally representative sample, as well as by race or ethnicity, education, and family income.

METHODS AND RESULTS: A total of 2254 older adults ≥60years (57% female, 79% non-Hispanic White) in the National Health and Nutrition …

Protocol For Developing A Personalised Prediction Model For Viral Suppression Among Under-Represented Populations In The Context Of The Covid-19 Pandemic, Jiajia Zhang Ph.D., Xueying Yang Ph.D., Sharon Weissman, Xiaoming Li Ph.D., Bankole Olatosi Ph.D.

Faculty Publications

Introduction Sustained viral suppression, an indicator of long-term treatment success and mortality reduction, is one of four strategic areas of the 'Ending the HIV Epidemic' federal campaign launched in 2019. Under-represented populations, like racial or ethnic minority populations, sexual and gender minority groups, and socioeconomically disadvantaged populations, are disproportionately affected by HIV and experience a more striking virological failure. The COVID-19 pandemic might magnify the risk of incomplete viral suppression among under-represented people living with HIV (PLWH) due to interruptions in healthcare access and other worsened socioeconomic and environmental conditions. However, biomedical research rarely includes under-represented populations, resulting in biased …

Consolidated Chamber Design And Protocol For Olfactory Conditioning Assay With Drosophila Melanogaster, Sasha Bronovitskiy, Andres Castillo, Michael Yan, Fang Ju Lin

Journal of the South Carolina Academy of Science

The olfactory conditioning assay is widely used in Alzheimer’s disease research to quantify learning and memory in Drosophila melanogaster. The assay tests ability to recall an aversive conditioned stimulus of scent paired with electrical shock when presented a choice between shock-associated and unrelated scents. The T-maze, a commonly used apparatus for olfactory conditioning assays, employs an elevator mechanism to transfer live flies from the shock-delivering training chamber to the scent selection point. This elevator mechanism is known to cause fly casualty. T-mazes are not commercially available and often difficult to reproduce. Other existing variations of olfactory conditioning apparatuses use …

Detecting Medication-Taking Gestures Using Machine Learning And Accelerometer Data Collected Via Smartwatch Technology: Instrument Validation Study, Chrisogonas Odero Odhiambo, Lukacs Ablonczy, Pamela J. Wright, Cynthia F. Corbett

Publications

BACKGROUND: Medication adherence is a global public health challenge, as only approximately 50% of people adhere to their medication regimens. Medication reminders have shown promising results in terms of promoting medication adherence. However, practical mechanisms to determine whether a medication has been taken or not, once people are reminded, remain elusive. Emerging smartwatch technology may more objectively, unobtrusively, and automatically detect medication taking than currently available methods. OBJECTIVE: This study aimed to examine the feasibility of detecting natural medication-taking gestures using smartwatches. METHODS: A convenience sample (N=28) was recruited using the snowball sampling method. During data collection, each participant recorded …

Search For B Mesogenesis At Babar, J. P. Lees, V. Poireau, E. Grauges, A. Palano, G. Eigen, D. N. Brown, Yu. G. Kolomensky, M. Fritsch, H. Koch, R. Cheaib, C. Hearty, T. S. Mattison, J. A. Mckenna, R. Y. So, V. E. Blinov, A. R. Buzykaev, V. P. Druzhinin, E. A. Kozyrev, Milind Purohit, Et. Al.

Faculty Publications

A new mechanism has been proposed to simultaneously explain the presence of dark matter and the matter-antimatter asymmetry in the Universe. This scenario predicts exotic B-meson decays into a baryon and a dark-sector antibaryon (ψD) with branching fractions accessible at B factories. We present a search for B→Λψ_D decays using data collected by the BABAR experiment at SLAC. This reaction is identified by fully reconstructing the accompanying B meson and requiring the presence of a single Λ baryon in the remaining particles. No significant signal is observed, and bounds on the B→Λψ …
