Stories From North Carolina Teachers Of Color: An Inquiry Of Racialized Experiences In The Workplace., Deborah Stephanie Harrison

Theses and Dissertations

Growing educational research shows that teachers of color are finding themselves working in racially hostile schools through experiencing racism from their White colleagues in explicit and inexplicit ways. There is a need to further categorize how North Carolina teachers of color are experiencing racism in the workplace and identify how they are affected by it through experiential knowledge and analysis underpinned by critical race theory. Through action research, this study’s goals incorporated the implementation and evaluation of a collaborative book as a method of intervention on the effects of racial trauma. The collaborative book presents full counternarratives of teachers of …

Spin Mediated Topological Black Hole In Acoustic Metamaterials Near Dirac-Like Cone Frequencies., Mustahseen Mobashwer Indaleeb

Theses and Dissertations

A unique bulk-boundary distinction and acoustic topological phenomena is discovered and explained in this dissertation. The overall objective was to discover the hidden physics, dynamic and mechanics of acoustic wave behavior that causes the formation of extremely rare ‘Topologically protected Black Hole’ (TBH) in acoustic microarchitecture metamaterials. This behavior is immensely valuable for numerous mechanical and civil engineering applications where acoustic insulators are required to create sound-free or vibration-free exterior surfaces. On the other hand, to contain the energy within the structure, for impact mitigation and energy absorption in vehicles, space crafts, aircrafts, and civil infrastructures such materials will be …

An Investigation Of The Galenic Influence On The Artistic Depiction Of Anatomical Concepts During The Renaissance, Fatima Amjad

Theses and Dissertations

The Renaissance era was a period marked by an intellectual and artistic resurgence in Europe, during which artists sought inspiration from Classical sources. This resulted in a move away from stylized medieval aesthetics and towards a renewed emphasis on accuracy and humanity in art. Renaissance artists developed art styles that emphasized perspective, proportion, and anatomy, creating more lifelike and naturalistic representations of the human figure and the natural world. The adoption of naturalism and individualism in the arts paired with the rediscovery and retranslation of ancient anatomical texts propelled artists and anatomists to deepen their understanding of the human body. …

Cultivating Community In A Sixth-Grade Classroom: An Action Research Study, Jennifer Weller Wells

Theses and Dissertations

Students who experience trauma bring this trauma to school with them in the form of exaggerated behaviors—acting out or withdrawing, being violent or extremely passive, or exhibiting rudeness or academic difficulty. Because students react to trauma in many ways, there is no one way for teachers to respond. The classroom community is vulnerable to the sheer unpredictability of behaviors. Grounded in ecological systems theory, whole-child theory, and compassionate teaching theory, this study explored my efforts to mitigate the results of trauma and increase the sense of community and well-being in my sixth-grade classroom. During the last few weeks of the …

Real-Time Facial Expression Recognition Using Edge Ai Accelerators, Mark Heath Smith

Theses and Dissertations

Facial expression recognition is a popular and challenging area of research in machine learning applications. Facial expressions are critical to human communication and allow us to convey complex thoughts and emotions beyond spoken language. The complexity of facial expressions creates a difficult problem for computer vision systems, especially edge computing systems. Current Deep Learning (DL) methods rely on large-scale Convolutional Neural Networks (CNN) which require millions of floating point operations (FLOPS) to accomplish similar image classification tasks. However, on edge and IoT devices, large-scale convolutional models can cause problems due to memory and power limitations. The intent of this work …

A Study Of Single Molecule Detection With Graphene Hall Bars, Kenneth Stephen Stephenson

Theses and Dissertations

In 2007, detection of individual molecules with a solid-state gas sensor was reported for first time by Schedin et al. where they used micromechanically-cleaved graphene for their sensing material, which exhibits isotropic and homogeneous conduction [1]. However, despite the novelty and popularity of their work, it has never been repeated. Further, we found their associated calculations to be self-inconsistent by a factor of 103 . So, hoping to account for and resolve this discrepancy, we outline the plan we had to reproduce their experiment. We also justify any substantial modifications, particularly our choice to use epitaxial graphene instead. Then, we …

Leveraging Automated Fiber Placement Computer Aided Process Planning Framework For Defect Validation And Dynamic Layup Strategies, Joshua Allen Halbritter

Theses and Dissertations

Process planning represents an essential stage of the Automated Fiber Placement (AFP) workflow. It develops useful and efficient machine processes based upon the working material, composite design, and manufacturing resources. The current state of process planning requires a high degree of interaction from the process planner and could greatly benefit from increased automation. Therefore, a list of key steps and functions are created to identify the more difficult and time-consuming phases of process planning. Additionally, a set of metrics must exist by which to evaluate the effectiveness of the manufactured laminate from the machine code created during the Process Planning …

The Effects Of Gamified Peer Feedback On Student Writing In High School English Language Arts, Kerise Amaris Broome

Theses and Dissertations

National assessments on writing show that student proficiency is low in part because many high school students lack revision skills. Compounding the problem is that as classroom sizes grow, teachers have less time to give the feedback that students need to improve. Peer feedback shows promise in being able to solve the feedback problem, but it must be carefully structured to be effective. The purpose of this action research was to evaluate the impact of gamified peer feedback in a high school English Language Arts classroom at Southern Charter High School. Three research questions guided this study: (1) What impact …

The Relation Between Adhd Symptoms And Life Satisfaction/Self-Esteem Among Youth: Family Structure And Parenting Practices As Moderators, Yvette Rother

Theses and Dissertations

Children and adolescents with attention-deficit/hyperactivity disorder (ADHD) may be particularly vulnerable to lower life satisfaction and self-esteem, given negative perceptions about their abilities and self, as well as related impairments in academic, social, and interpersonal functioning. Family factors, such as family structure and parenting behaviors, can impact youth development and behaviors. However, it is unclear what role family factors play in the relation between ADHD symptoms and life satisfaction and self-esteem among youth. This study therefore examined whether ADHD symptoms have an impact on the life satisfaction and self-esteem of children and adolescents in grades 4-12. Moreover, it explored whether …

Constructing Selfhood Through Fantasy: Mirror Women And Dreamscape Conversations In Olga Grushin’S Forty Rooms, Grace Marie Alger

Theses and Dissertations

By its very nature, fantasy seeks to estrange its protagonist and readers from reality, leading to the exploration of topics that would generally be left isolated or unchallenged. Fantasy allows a character to step outside of reality in order to examine the conditions of their existence, to question their own position in society, and to reflect upon the ideologies that determine their social positioning. Analyzing Olga Grushin’s Forty Rooms (2016), this thesis examines the ways in which the female narrator turns to fantasy, more specifically, dreamed conversations and visions of multiplied selves, in an attempt to overcome the powerlessness of …

Jewish Genetic Diseases: Knowledge Of Reproductive Risk And Cancer Predisposition Among Young Adults Of Ashkenazi Descent, Hayley Kathleen Granger

Theses and Dissertations

Founder mutations within the Ashkenazi Jewish (AJ) population are associated with significantly higher carrier rates for certain severe, life-limiting conditions collectively called Jewish Genetic Diseases (JGDs), and for pathogenic variants in the BRCA1 and BRCA2 (BRCA1/2) cancer susceptibility genes. Efforts to educate AJ individuals about the implications of these founder mutations and available testing have increased the past forty years; however, studies suggest AJ individuals are not well educated on the topic (Hardy et al., 2022; Kaback, 2001; Warsch et al., 2014). Studies evaluating the reason for this gap in knowledge of young AJ adults are lacking. This study aimed …

Detecting Physiological Concentrations Of Alzheimer’S Associated Amyloid-Β Protein Utilizing A Cell-Based Response, Brittany Elizabeth Watson

Theses and Dissertations

Alzheimer’s disease (AD) is characterized symptoms of cognitive impairment resulting from blood-brain barrier (BBB) breakdown and neuronal cell death. AD is associated with aggregated amyloid-β (Aβ) plaques deposited around brain vasculature and within the brain. Changes in the brain occur up to 20 years before symptoms arise; however, there is currently no pre-symptomatic detection method available for AD. An intact BBB requires tight junction proteins (TJs) that render relatively high transendothelial electrical resistance (TEER). AD-associated breakdown of the BBB correlates with vascular Aβ deposition, suggesting that aggregated, pathological Aβ can modulate TEER. We explore leveraging this cellular response for early …

Experiences Of Parents Of Children With Late-Onset Pompe Disease Diagnosed By Newborn Screening, Allison Marie Paltzer

Theses and Dissertations

Pompe disease is an autosomal recessive lysosomal and glycogen storage disorder. It is classified as either infantile-onset Pompe disease (IOPD), which is characterized by severe muscle weakness and enlarged heart shortly after birth, or late-onset Pompe disease (LOPD), which is characterized by more slowly progressive weakness without obvious symptoms at birth. Pompe disease was added to the Recommended Uniform Screening Panel (RUSP) for newborn screening (NBS) in 2015 as early treatment with enzyme replacement therapy is lifesaving for children with IOPD. However, most patients identified via newborn screening have LOPD, which does not require immediate treatment and may not present …

Using Factor Mixture Modeling To Counter Faking, Raul Corrêa Ferraz

Theses and Dissertations

Self-reports (SRs) of typical behavior are often the only existing feasible method to gather data on important drivers of human performance. In applications such as personnel selection, SRs are vulnerable to intentional distortions, often referred to as faking. A review of the literature suggests that so far, the methods proposed to address faking are unsatisfactory. In a recent breakthrough, Pavlov et al. (2019) showed that high-stakes scale scores are best modeled as a function of a) propensity to fake, b) honest scores, and c) the interaction of these two terms. Pavlov et al. did not, however, propose any method to …

“It Looks Like The Future But Feels Like The Past”: Oral (Hi)Stories Of Appalachia As Covid-19 News Stories, Ashley Reid Mcgraw

Theses and Dissertations

Oral historians have often felt obligated to collect stories during disasters and crises, to preserve recollections of experiences and trauma of those affected. During the onset of COVID-19 in the United States, this surge was certainly present. Appalachia, although its boundaries are contested, has a strong association with oral histories, and thus was the focus of one project in particular: a collaboration with the Blue Ridge Public Radio and the Foxfire Appalachian Heritage Museum to collect, curate, publish, and broadcast oral histories of "local" individuals. But what does it mean to be local, in a region as broad as Appalachia? …

Load Rating Evaluation Of Deteriorated Prestressed Channel Girders, Alexander Zane Henderson

Theses and Dissertations

The South Carolina Department of Transportation (SCDOT) is conducting a multi-year effort to load rate its inventory of over 9,400 bridges. This includes many bridges that are load posted due to potential structural considerations (e.g., outdated design loads, members whose capacity is difficult to assess, structural degradation). The number of load-posted bridges in South Carolina is expected to increase significantly due to recent efforts from SCDOT to assess the current state of bridge infrastructure. It is expected that the increased scrutiny may result in more load postings, which in turn may lead to restrictions on truck routes, potential bridge closures, …

From Derby Tracks To Surf Shacks: Reflections Of California’S Changing Cultural Landscape Through Artistic Renditions Of Recreation 1930s-1960s, David Walls

Theses and Dissertations

The aim of this thesis is to analyze works of art originating in the state of California during the 20^th century to better understand how sports and recreation were used as a subject matter to reflect upon the state’s changing cultural landscape. This changing landscape encompasses a wide range of social, cultural, economic, and political topics, however, the topics of race, migration, and economic strife are the most consistently reflected in the artistic production of this time and must be emphasized. Scholarship of art created within this region and timeframe has neglected the impact of recreational subject matter and …

Role Of Sediment Type, Concentration, And Salinity On Clay Flocs, Ryan Michael Johnson

Theses and Dissertations

Experiments were performed to study floc formation in water bodies. In particular, the study aimed to systematically identify effects of water depth, time, salinity, initial clay concentration, and clay type on floc formation and settling. Three sediment types were chosen for this research are Three sediment types were chosen for this research: silica powder, with particle sizes comparable to clay flocs, kaolin clay and bentonite clay. Silica was chosen as a control because it did not form flocs. Kaolin represented low activity clay; bentonite was chosen as the high activity clay. Experiments lasted up to 48 hours. Graduated cylinders were …

“Speak For Yourself”: Ovidian Women And The Suppression Of Voice And Complaint In Metamorphoses And Heroides, Grayson Elizabeth Newman

Theses and Dissertations

Ovid’s portrayal and attitude towards women is one that is particularly puzzling and contradictory throughout his Metamorphoses and Heroides. Recent scholarship on Ovidian literature is only divided on whether or not Ovid’s intentions within these two works were to sympathize with the Roman woman’s experience or to reinforce the lack of female representation in Roman society; however, I argue that Ovid fails to achieve empathy for the Roman woman. In Heroides, these women are pining and tragic, often meeting some terrible fate shortly after being abandoned by their suitors and putting forth a complaint. Conversely, women in Metamorphoses …

Deficit Thinking In Teacher Course Level Recommendations, Andrew Hogan

Theses and Dissertations

The purpose of this study was to analyze teacher perceptions of the impact of deficit thinking in student course level placement to derive greater insight into the causes of the over-representation of students of color in lower-tracked classes. This study was conducted as a virtual focus group using Google Meet that took place across 3 meetings in which 6 teachers participated in activities designed to promote dialogue around the impact of deficit thinking in the placement of students into course levels.

The Effects Of Problem-Based Learning On Mathematics Motivation In A Flipped Classroom Instructional Environment, Joshua David Harrison

Theses and Dissertations

In response to decreasing motivation in high school math classrooms, teachers are transforming classrooms with various instructional techniques. Traditional math instruction relies on direct instruction and memorization of content, processes, and skills. Teachers are transitioning to more constructivist student-led approaches. Utilizing multiple instructional designs provides teachers more opportunities to access the major components of the ARCS Model: attention, relevance, confidence, and satisfaction.

Therefore, the purpose of this action research was examining problem-based learning in a flipped classroom instructional environment and measuring its effect on students’ motivation and achievement in Algebra 2. The study addressed the following research questions: 1) What …

Assessing The Gaps And Potential Solutions To Improve Access To Genetic Testing For Autistic Individuals, Nisha Dhiren Pandya

Theses and Dissertations

The prevalence of Autism Spectrum Disorder (ASD) continues to increase. Numerous genetic syndromes increase the risk of ASD. Professional organizations have published guidelines on the genetic testing recommended for Autistic individuals. However, healthcare providers do not unanimously offer genetic testing or refer for a genetics evaluation. Notably, parents of Autistic individuals express interest in learning about genetic testing as an option for their children.

This study aimed to identify gaps to improve access to genetic evaluations for Autistic individuals and their families. A survey was sent to healthcare providers across the United States that currently see Autistic individuals. We expected …

Understanding The Spectrum Of Cacna1a Related Disorders: An Analysis Of Genotypes And Phenotypes In 416 Individuals, Olivia Jane Wilmarth

Theses and Dissertations

Pathogenic variants in the CACNA1A gene disrupt a calcium channel expressed in the central nervous system, causing a variety of neurological and psychiatric features collectively known as CACNA1A-related disorders. Gain-offunction and loss-of-function of this channel are both well-established mechanisms of disease, but specific genotype-phenotype correlations have remained unclear. Previous research has been limited by small sample sizes, with some studies noting significant intrafamilial variation and reduced penetrance. This study aimed to collect and analyze genotypic and phenotypic data from a large sample of individuals with CACNA1A-related disorders published in the literature and in two patient cohorts. Using the …

Expanding Tailorable Nanomaterial Synthesis With Persistent Micelle Templates, Eric R. Williams

Theses and Dissertations

The control of block polymer micelle dimensions while in solution is critical for a range of emerging applications in diverse fields from drug delivery and nanoreactors to use as sacrificial templates for porous nanomaterials. When under kinetic control, micelles will maintain a constant average size and thus aggregation number (N_agg) through the suppression of chain exchange mechanisms. Such kinetic control effectively enables the decoupling of micelle dimensions from solution conditions. In other words, kinetically trapped micelles can resist reorganizations brough about by e.g., the addition of metal nanoparticles. However, such micelles are traditionally governed by a fickle �� …

Experimental Observation Of Sphere Symmetric Isolated Single Droplet Combustion In A Converging Channel, Mason Carrington Williams

Theses and Dissertations

Spherically symmetric isolated single droplet combustion has been observed mainly in microgravity conditions. This study sought to determine if spherically symmetric combustion can be produced in a lab-scale experiment using flow acceleration to counteract the effects of buoyancy. The experiment was conducted in a converging channel that decreased in width along its length to accelerate the flow and limit the formation of a boundary layer. The rate at which the area decreased was governed by the initial velocity condition set at the channel inlet.

The droplets were generated using a piezoelectric actuator which forced fuel out of an injector with …

Impact Of Virtual Models On Students’ Multilevel Understanding Of An Organic Reaction, Eli Martin

Theses and Dissertations

As the number of STEM opportunities and the need for a scientifically literate society increases, educators in STEM fields require tools that help support these needs. Chemistry is one STEM content area that would benefit from exploring educational technology that supports conceptual understanding. An action research study was conducted to understand how students engage with the content and virtual representation to develop their understanding of a chemical reaction. This convergent mixed methods study looked at the effect of dynamic virtual molecular representation on students' ability to understand a reaction mechanism at the symbolic and subparticulate level by measuring content knowledge …

The purpose of this mixed methods action research study was to investigate the impact of collaborative teaching involving a school librarian and a social studies teacher on sixth-grade students’ unit projects, classroom engagement, and digital literacy skills. This study's innovation was twofold: academic content was infused with digital literacy skills instruction, and the librarian/researcher co-taught the unit with a regular academic content teacher. The study was designed to answer three research questions involving how instruction that integrates digital literacy and social studies content taught collaboratively by a librarian and social studies teacher influences sixth-grade social studies students’ performance on summative …

Rhetorical New Materialism, Queers, And Cringe, Katherine Anne Schell

Theses and Dissertations

Cringe, the negative reflexive reaction we experience when we witness something embarrassing or awkward, has a bad reputation in the queer community. In online and physical queer spaces, there is a pervading belief that “cringe culture” must be antithetical to queerness, that no queer community could possibly achieve liberation until it has eradicated the threat of cringe. This thesis revises that cringe vs. queer positioning by reimagining cringe as its own rhythm of queerness and examining the productive aspects of cringe through engagement with thinkers like Karen Barad and Eve Kosofsky Sedgwick. The thesis, formatted as a response to a …
