Department of Communication Sciences and Disorders Faculty Scholarship and Creative Works

Purpose: This preliminary case series investigated the effects of biofeedback intervention for residual rhotic errors delivered within a modified challenge point framework. In the challenge point framework, practice difficulty is adaptively adjusted with the goal of enhancing generalization learning. This study more specifically evaluated the feasibility of a computer-mediated implementation of challenge point treatment for rhotic errors using a custom open-source software, the Challenge Point Program.

Method: Participants were five native English speakers, ages 7;3–15;5 (years; months), who had established but not generalized correct rhotic production in previous treatment; overall treatment duration was flexible. Treatment incorporated either electropalatographic …

Interactions Between Stress, Ethanol, And Thc Exposure And Effects On Prefrontal Reliant Signaling And Behavior, Cora E. Smiley

MUSC Theses and Dissertations

Post-traumatic stress disorder (PTSD) and substance use disorder (SUD) are two highly prevalent and highly debilitating psychological conditions that often occur comorbidly. In accordance with the self-medication hypothesis, drugs like alcohol and cannabis are used following exposure to a traumatic event to acutely reduce anxiety, but, in the long term, these substances cause impairments in learning and memory processes in the prefrontal cortex and reduce the effectiveness of therapeutic treatments for these disorders. As such, the overarching hypothesis of this dissertation is that exposure to stress, alcohol, and cannabis lead to alterations in learning and memory due to modifications in …

Día De (Los) Muertos - The Revered Mexican Holiday Of Death, Logan Johansen

Undergraduate Research Journal

In recent years, Americans have become enthralled with what many might refer to as Mexican Halloween. Notably, the Disney film Coco in 2017 portrayed a fantastical interpretation of the holiday, combining music and a wholesome story typical of the company’s many animated films. Although the celebration falls just after October 31st, the traditional holiday is not an imitation of the Americanized All Hallows’ Eve. Yes, there are costumes, candy, and lots of partying, but the purpose and intent of the holiday is entirely different. With rapidly growing popularity in the United States and even across the world, it is important …

Feminine Intervention: The Bosnian War And Women’S Roles In Instigating Peace, Ashly Helfrich

Undergraduate Research Journal

Women played a significant role both during and after the Bosnian conflicts throughout the 1990s, as they prioritized their continuation of traditional roles in their homes and families, while also promoting gender equality and women’s roles in peacekeeping processes. Women who were directly involved in the aftermath of the Bosnian war often reinforced traditional gender stereotypes through their connections to their roles as mothers and wives, and their emphasis on the relationship and care of individuals who had been physically and mentally traumatized by the war. In response to the brutal rapes and human rights violations that occurred during the …

Transcutaneous Auricular Vagus Nerve Stimulation (Tavns): Long-Term Effect On Neurodevelopment And Sensory Performance, Turki Khaild Aljuhani

MUSC Theses and Dissertations

Infants who do not succeed at early feeding are likely discharged from the nursery with a gastrostomy tube (G-tube), putting them at risk for worse neurodevelopmental and sensory outcomes than infants who achieve full oral feeds. This study aims to investigate the impact of Non-invasive transcutaneous auricular vagal nerve stimulation (taVNS) on infants' early motor development and long-term neurodevelopmental sensory performance at 18 months. Besides the observed feeding improvement using taVNS paired with bottle-feeding, we explore if pre-treatment total STEP scores' is able to predict response to taVNS intervention. The pre-treatment total STEP scores did not contribute to the prediction …

Brca1 And Brd4: Regulation Of Chromatin Signaling In Dna Repair And Transcription, John Kaiser Barrows

MUSC Theses and Dissertations

The eggs of Xenopus laevis frogs have been used extensively to study various aspects of chromatin biology. In this document, we characterize two novel systems to study transcription (Chapter 2) and DNA double strand break repair (Chapter 4) utilizing different egg extracts. Notably, we show that nucleoplasmic extract is the first established Xenopus egg extract to support RNA polymerase II-mediated transcription of plasmid-borne gene constructs. Using this cell-free transcription system, we provide the first evidence of a molecular connection between the tumor suppressor, BRCA1, and the major epigenetic regulator, BRD4 (Chapter 3). We show BRCA1, along with its constitutive binding …

A Hebrew Republic Of Taxation?: Henry George’S Single Tax, Hebraic Law, And Unearned Income, Joshua Cutler

Accountancy Faculty Publications and Presentations

Can millennia-old religious ideas offer insights into modern tax law? I explore this question through the hugely popular, yet largely forgotten, tax movement of political economist Henry George. Seeking to explain why poverty always seemed to increase along with progress, George proposed that, as societies advanced, land owners were able to capture an increasing share of unearned wealth. To remedy this, George proposed a “Single Tax” on the unearned income from land. George’s tax movement gained popularity largely because it was founded on widely-held ideas originating in the Hebrew Bible. Yet, the religious foundation of George’s tax movement has been …

We include auxiliary steps that provide new users with tools and strategies that will help troubleshoot key steps in the process. This protocol is one of the safest, cheapest, and most reproducible approaches for the detection of SARS-CoV-2 RNA in wastewater. Furthermore, the RNA obtained using this protocol, minus the pasteurization step, can be sequenced both using a targeted approach sequencing specific regions or the whole genome. The protocol …

Women’S Political Leadership And Adult Health: Evidence From Rural And Urban China, Hongwei Xu, Nancy Luke, Susan E. Short

Publications and Research

This study examined the role of women’s political leadership at the community level in China, a context that has experienced recent political and socioeconomic change and has a distinctive rural-urban divide. Drawing on longitudinal data from the China Family Panel Studies (N = 40,918~52,406 person-year observations), we found that female community directors outnumbered male directors in urban China but were much less common in rural areas. Female community directors had higher levels of human capital regardless of rural or urban location. Residents living in female-directed communities reported better mental health, but not physical health or life satisfaction, compared to those …

Bird Abundance And Diversity And The Impact Of Oyster Reef Restoration On The Bird Community In Mosquito Lagoon, Florida, Usa, Jessica Copertino

Electronic Theses and Dissertations, 2020-2023

Birds are often used as indicators for biodiversity and ecosystem health. While birds have been monitored in other parts of the Indian River Lagoon (IRL), there has been little research on birds in Mosquito Lagoon (ML, the northernmost portion of the IRL). This thesis first examines the abundance and diversity of birds in ML by using two years of photographic observations to assess seasonal variations and the use of various habitat features by specific bird taxa. Abundance and species richness were highest in winter, while evenness and Simpson's diversity were highest in summer. Moreover, natural and artificial habitat features were …

Their Bodies Flamboyant: An Exploration Of Self Through Figuration And Flower, Gabriel Cortese

Electronic Theses and Dissertations, 2020-2023

This thesis explores my relationship to artmaking through the exploration of my identity. As a gay, Puerto-Rican, Argentinian, American man, my relationship to art has always been a way for me to make sense of my intersectional experiences. Chronologically recounting past and current bodies of work, I explain how my personal growth coincides with my artwork. From once shameful, hidden figures to later flamboyant, unapologetic bodies, this thesis links the sequential evolution of my figuration and ideas. I also investigate the process of reclaiming moments in art history as being inherently queer and explore the ways in which they manifest …

Forensic Implications For The Diagenetic Alteration Of The Stable Isotopic Composition Of Pig Ribs Following Exposure To Aqueous Conditions., Erin Martin

Electronic Theses and Dissertations, 2020-2023

This research involves the examination of the contribution of stable isotope analysis to the forensic anthropological objective of human identification. Oxygen isotopes, which vary in water in a predictable manner according to climatological and geographical factors, can be used to determine the region of origin of an unidentified individual following isotopic analysis of human skeletal remains. However, stable oxygen isotopes from human remains recovered from various aqueous environments may be altered by diagenetic processes that occur following deposition. The focus of this research is to determine potential diagenetic changes in the oxygen isotopic value (d18O) of Sus scrofa (domestic pig) …

Non-Lethal Predictors Of Organ Level Metal Contaminants In Central Florida Red-Shouldered Hawks, Jennifer Bouchenot

Electronic Theses and Dissertations, 2020-2023

Elemental contaminants aggregate in the environment due to human activity and can induce detrimental physiological effects within organisms. Birds exhibit exceptional susceptibility to many pollutants and are popular biomonitoring agents throughout the world. Birds of prey are of special interest due to their substantial biomagnification potential. Lethal sampling of internal organs yields accurate contaminant measurements, but recent sampling trends are endeavoring towards non-destructive sampling such as feathers. This methodological shift stems from researchers' preference for less-regulated samples, enhanced animal welfare, and broadening the possible collaborative audience with simpler protocols. Unfortunately, investigations of feathers have shown that their accuracy is capricious …

Modulation Of Fat Taste By Diet And Hormones, Ashley Calder

Electronic Theses and Dissertations, 2020-2023

The prevalence of obesity worldwide continues to rise despite efforts to reverse the trend. While many factors contribute to the onset and maintenance of obesity, caloric intake and dietary composition have been shown be primary contributors. The oral cavity is one of the first systems to encounter food and determine its hedonic value. As the gateway to ingestion, the taste system plays a unique role in the initial decisions surrounding the control of food intake. Nutrients like carbohydrates, protein, minerals, and fat all have dedicated systems to allow their recognition at this outermost site of the enteric nervous system. Recent …

Bioarchaeological And Mortuary Patterns At Holtun, Guatemala: Integrating A Comparative Osteobiographic Approach, Horvey Palacios

Electronic Theses and Dissertations, 2020-2023

Bioarchaeological analysis can help identify patterns of mortuary ritual and social experience of ancient Maya peoples. However, there is limited bioarchaeological and mortuary evidence for the relationship between the development of social complexity and social experience. Particularly, how is social organization reflected in patterns of burial practice and skeletal markers of stress. This thesis uses osteobiographies to contextualize the mortuary and biological profiles of 20 individuals interred at the Maya site of Holtun, Guatemala to examine bioarchaeological variation during the Preclassic (800 B.C. – 250 A.D.) and Late Classic (550 A.D. – 900 A.D.) periods. This work highlights the integration …

CFR Publications

This dataset was compiled from the National Reservoir Research Program 1989 dataset. The NRRP dataset includes data from rotenone and creel studies at reservoirs throughout the continental US during the 1980s. We compiled the species level biomass data into total biomass for each of five trophic guilds (piscivores, detritivores, herbivores, invertivores, and planktivores). This compiled dataset was used to investigate the Cascading Reservoir Continuum Concept across 16 river basins in a study conducted by the 2020 Management of Impounded Rivers Class.

Effectiveness Of Digital Interactive Experiment In Learning Outcomes And Engagement, Matin Salemirad

Electronic Theses and Dissertations, 2020-2023

Despite some ongoing debates over the positive or negative impact of digital games, educational games are powerful tools to increase engagement and improve learning outcomes. Scientific concepts about the weather are complicated for younger learners and deep learning often requires long-term cultivation. This thesis presents a novel interactive educational simulation called the Science of Meteorology with Interactive Learning Experience (SMILE). In it, students interact with a touchscreen monitor to change weather conditions and learn about clouds and weather science. The relationship between engagement and learning outcomes and the effectiveness of the experience is evaluated using a formal user study. Online …

Optimizing The Use Of Normative Data In Dementia Diagnostic Evaluations, Laurie Holler

Walden Dissertations and Doctoral Studies

Cognitive tests are typically scored and interpreted using an appropriate normative reference group, often similar age individuals with similar levels of education. Psychometric testing theory presupposes that demographic correction is always beneficial, supporting the ubiquitous use of age and education correction in clinical practice. In the context of dementia, however, there is some evidence suggesting that demographic correction (specifically age correction) may reduce the sensitivity of cognitive tests to age-related cognitive decline. It was hypothesized that age correction would reduce the utility of cognitive tests for detecting cognitive change in individuals with mild cognitive impairment and mild dementia due to …

Stress Perceptions And Verbal Commands For Law Enforcement In High-Stress Situations, John Kenneth Gibson

Walden Dissertations and Doctoral Studies

Acute stress can have a negative effect on the physiology and cognitive performance of peace officers when they are engaged in high-stress situations. This could lead to injury or loss of life if a mistaken perception occurs or incorrect decision is made by the officer or suspect. The purpose of this qualitative phenomenological study was to explore the perceptions of stress for peace officers who issue verbal commands to an aggressive role-playing suspect in a use-of-force scenario. The theoretical framework was Lazarus and Folkman's transactional theory of stress and coping. Data were collected from observations, field notes, and semi-structured interviews …

Chief Officers’ Perspectives Of Traffic Incident Management Standards Following A Line-Of-Duty Fatality, Charles David Hughes

The purpose of this study was to explore chief fire officers’ perceptions of incident management policies and standards for the prevention of firefighter line-of-duty deaths resulting from secondary collisions. Their perceptions may contribute to the efficacy and appropriateness of incident management policies and standards and may also lead to recommendations to improve compliance. The research question was to understand what chief fire officers’ perceptions of incident management policies and standards for preventing firefighter line-of-duty-deaths from secondary collisions. The theoretical framework …

Common Mudpuppy (Necturus Maculosus) Distribution, Diet And Seasonality In Western New York And Morphological Condition In Lake And Stream Habitats., Adam M. Haines

Biology Theses

Environmental context changes the behavior and morphology of organisms. The impacts of flow on sampling techniques and morphology of the Common Mudpuppy were investigated during this study. I also explored mudpuppy distribution in western New York, diet, sexual dimorphism, seasonality, and capture biases. I found rock turning to be more efficient in streams year-round and modified minnow traps to be better more efficient in cold weather months and in deeper habitats than in other seasons or habitats. During the hot weather months, mudpuppy diet consisted of invertebrates exclusively, whereas diets in cold weather months consisted of invertebrates plus vertebrate prey. …
