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 …

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 …

Electronic Portfolios In A High School Community Of Practice: Action Research Exploring Writing Experiences In An Advanced Placement Writing Course, Archibald Franklin Harrison Iv

Theses and Dissertations

The underlying assumption of this study is that writing as a process has profound implications for success and fulfillment both in and beyond the classroom. A second assumption is that electronic portfolios provide students a space to write, revise, reflect, share, and explore themselves as writers. Students who engage with and embrace the writing process to the point that they self-identify as writers may be more likely to not only succeed at academic writing tasks but to integrate writing into their future lives (Lengelle and Meijers, 2014). For writing to play a prolonged role in this level of academic, professional …

Face Validation Of A Spanish Non-Invasive Prenatal Screening Knowledge Scale, Kenya Michelle De Leon

Theses and Dissertations

Non-invasive prenatal screening (NIPS) provides risk assessment for chromosome aneuploidy in pregnancy. Previous studies in the United Kingdom and United States have attempted to measure patient knowledge, decisional conflict, and informed choice in cohorts of English-speaking pregnant patients who elected NIPS (Griffin et al., 2023; Lewis et al., 2016). However, knowledge scales utilized in these studies have not been validated. The current study was conducted in order to assess face validity of a Spanish NIPS knowledge scale that was originally written in English. This scale was developed as part of a larger project to ultimately provide more validated research measures …

Projecting The Effects Of Climate Change And Urbanization On Longleaf Pine Stands In The Florida Flatwoods, Lilian Grace Hutchens

Theses and Dissertations

The southeastern United States once held millions of hectares of highly connected longleaf pine ecosystem. In a dramatic range reduction, longleaf pine now occupies less than 5% of its original extent, its remnant patches existing within a matrix of human-dominated land uses. Conservation planning for longleaf pine ecosystems is complicated given the ecosystem’s reliance on fire and the broad spatial and temporal scales at which longleaf pine management must operate. Planning timelines for longleaf pine management extend into the end of the 21st century, a period during which climate, fire regimes, and land cover are all expected to change, influencing …

How Do They Do It: A Narrative Of Disabled Public School Instrumental Ensemble Conductors And Their Positive Working Relationships With Their Administrators, Lia Alexandria Patterson Snead

Theses and Dissertations

As the leader of the instrumental ensemble, the conductor’s role is important on and off the stage. Public school conductors have especially demanding jobs because they must act as a conduit between composer and ensemble as well as handle all administrative duties pertaining to running a music program. Subsequently, this results in a heavier workload than the average teacher. The demanding workload can add to any preexisting issues for disabled ensemble conductors who struggle at work due to insufficient support from their administrators. The lack of strong administrative support for disabled or impaired faculty and staff may be due to …

A Causal Comparative Study Of The Effects Of Physical Activity Course Enrollment On College Students’ Perceived Wellness, Mental Health, And Basic Psychological Needs, Genee’ Regina Glascoe

Theses and Dissertations

On college campuses, there has been an increase in mental health needs among students. In 2019, 56% of students attended counseling for mental health concerns compared to 46% of students who attended in 2010 (The Center for Collegiate Mental Health, 2019). Colleges have begun focusing on student wellness to assist their students with the capability to thrive during their college years and beyond (LaFountaine et al., 2006). Basic psychological needs must be met to achieve psychological growth and wellbeing (Ryan & Deci, 2000b; Zhang et al., 2012). Taliaferro et al. (2009) found evidence of an association between physical activity and …

Identity In Literacy Narratives: Toward Reflexive Pedagogy In First Year Writing, Laiken Elizabeth Harrigan

Theses and Dissertations

An ongoing discussion for composition pedagogues is the relation of individuals’ identities and discourse histories in relation to academic discourses. In this thesis, I argue that academic discourse cannot be entirely separated from personal discourse, as individuals are always in conversation with their discoursal histories and identities. In order to better understand how students perceive their relationships to academic discourse, I analyze how First Year Writing (FYW) students experience the discourse of FYW— where they either intertwine their identities or we see their personal identities collide with the academic space. I used open coding to conduct a textual analysis of …

Understanding Intergenerational Transmission And Frequency Of Ethnic-Racial Socialization Practices Among Racial Ethnic Minority Groups, Ryan Chantz Houston-Dial

Theses and Dissertations

Ethnic-racial socialization (ERS) is a multidimensional concept that can be defined as the transmission of attitudes, beliefs and messages about ethnic-racial group membership (Hughes et al., 2006). To counteract the negative effects of discriminatory experiences, ethnic minority parents proactively impart race-salient messages to their youth. Sociodemographic variables such as regional location has been shown to affect the frequency of ERS messages as well (Thornton et al., 1990). The current study examines ERS practices in 436 African American, Hispanic/Latinx and Asian American parents. This study also explores the concept of intergenerational transmission, in which parents pass on to their own children …

A Conductor’S Guide To Lucrecia Roces Kasilag’S Misang Pilipino (1965), Denise Ysabel Ellis

Theses and Dissertations

Composer Lucrecia Roces Kasilag (1918-2008) is a National Artist for the Philippines and a UNESCO International Artist of the World. Though she has many more accolades and triumphs to note, both national and international, Kasilag is not well known outside of her native Philippines. One factor that obscures this composer from the world is that much of her work is unpublished, as are other historical Filipino composers’ works.

Kasilag composed her first Misang Pilipino in 1965 to commemorate the 400^th year of Christianization in the Philippines, but multiple editions of the work were written and used for different occasions. …

Planting Rhizomes: Roots And Rhizomes In Maryse Condé’S Traversée De La Mangrove And Calixthe Beyala’S Le Petit Prince De Belleville, Rume Kpadamrophe

Theses and Dissertations

For centuries, migration has played a crucial role in the development of human civilization, with the transplantation of cultures from one region to another shaping identities worldwide. The African diaspora, beginning with the Atlantic Slave Trade, saw the forced transportation of around 12 million Africans across the ocean, resulting in the creation of creole identities in the Antilles. Literature has long reflected the experiences of migrants. In Maryse Condé's Traversée de la Mangrove and Calixthe Beyala's Le Petit Prince de Belleville, the complexity of Antillean and Afro-French identities is explored. This thesis delves into how Condé's work highlights the …

The Impact Of The Flipped Classroom Model On Elementary Students’ Achievement And Motivation For Learning Geometry, Kimberly M. Smalls

A Flood Of Information: Assessing The Effectiveness Of An Enhanced Flash Flood Warning Social Media Graphic, Christopher John Long

Theses and Dissertations

Flash flooding is the most frequent and damaging type of severe weather globally. In the United States, heat is the only weather-related cause of death more frequent than flooding. However, while the number of deaths associated with other types of severe weather has decreased since the 1950s, the number of flash flood-related deaths has remained steady. Therefore, there exists a need to improve flash flood warning communication.

In this project, it is hypothesized that improving the National Weather Service’s flash flood warning social media graphic by including areas that commonly flood may increase individuals’ perceived storm risk, their intended compliance …

Genetic Testing For Autism: The Autistic Adult Perspective, Thomas Scott Dent

Theses and Dissertations

Many professional medical organizations recommend some level of genetic testing as standard of care for those diagnosed with autism spectrum disorder. However, genetic testing related to the diagnosis of autism is seen as controversial by many in the autistic community. While opinions about genetic testing have been well-documented from the perspective of the parents of autistic children, our understanding of the autistic adult perspective remains limited. We implemented a descriptive, web-based survey of autistic adults to assess their awareness of, attitudes towards, and interests in genetic testing for autism (n = 145). Our data demonstrated that half of our participants …

Evaluating Health Awareness In Cancer Genetics Amongst The Black And African American Community In South Carolina, Annika Jaliya Gadson

Theses and Dissertations

Historically minoritized individuals are underrepresented in genomic research which limits the ability to fully understand genetic variation within the population (Sirugo et al., 2019). This creates bias that questions the effectiveness of guidelines for genetic testing, predictive risk values, and medical management. Disparities in cancer genetics may be attributed to historical events that have cultivated mistrust in research and medicine, institutional bias, provider skepticism in patient reporting of medical symptoms, and limited access to genetic testing (Saulsberry et al., 2013). More exploration is needed to better understand how to increase access and awareness of cancer genetic services to Black and …

Advancements In Parametric Modal Regression, Qingyang Liu

Theses and Dissertations

This dissertation considers statistical inference methods for parametric modal regression models. In Chapter 1, we motivate the mode as the measure of central tendency instead of the median or the mean with an example. Following the motivational example, we include an overview of existing modal regression models. Later, in the same chapter, we explain advantages of the parametric modal regression models over existing nonparametric modal regression models. In Chapter 2, we address issues in statistical inference brought in by data contaminated with measurement error. With measurement error in covariates, statistical inference methods designed for modal regression models with error-free covariates …

Outliers To The Black Experience: Perceptions Of How Participation In Internships And Study Abroad Influences Black Students’ Development Of Career Readiness Competencies, Erica James Lake

Theses and Dissertations

Black students represent nearly 15% of the college student population, yet nationally only 6% of these students participate in internships and study abroad. Comparatively, White students represent approximately 52% of the college student population, and they represent over 70% of the students who participate in internships and study abroad. This is significant because internships and study abroad experiences can help students gain access to mentors and improve their retention and graduation rates. This study sought to determine if Black students believed they gained career readiness competencies during their experiences.

This qualitative study included interviews, observations and photos from Black seniors …
