Using Latent Class Analysis To Conceptualize Heterogeneity Among Non-Resident Parents With Current Child Support Orders And Arrears: Identifying Windows Of Opportunity, Victoria Adkins Charles

Theses and Dissertations

Approximately 40% of children living in poverty are in a single parent household headed by their mother (Grall, 2017). The public child support services program exists to provide the service of establishing and enforcing child support orders for parents with primary legal custody of their child. Even with the child support services system in place, child support goes uncollected (Grall, 2020). Many of the non-resident parents (NRP) who are not paying live at poverty level as well. Child support research has focused primarily on NRPs’ ability to pay, but, generally, has drawn on the information contained in the constellation of …

The advent and consequential advancements in geotechnical earthquake engineering has made soil-structural analysis (SSI) an important component in the analysis and design of earthquake resistant structures. The filtering effects of pile foundations which reduces the seismic demand on pile-supported superstructure when they are subjected to seismic waves have been investigated and confirmed by several researchers in the last 40 years. To this end, several methods of analyzing the effects of SSI have been developed over the years. From the simplified Winkler model to the more robust finite element method (FEM) and boundary element method (BEM), researchers and structural engineers alike …

Illuminating The Twilight Zone: In-Situ Imaging Facilitates Discovery Of Mesopelagic Plankton Dynamics And Community Structure, Alexander Barth

Theses and Dissertations

Ocean ecosystems provide both food and regulation of climate. Much of ocean ecosystem functioning occurs through processes in the pelagic, where plankton are the dominant organisms. While plankton have been researched for several centuries, recent advances in technology are greatly improving the ability to better understand plankton and how their communities are structured. Specifically, in-situ imaging allows oceanographers and plankton ecologists to better sample fragile taxa and record organisms’ true traits at high frequencies. These tools can facilitate investigation into new topics in plankton ecology and better understand critically understudied habitats, like the mesopelagic of open-ocean systems. However, in-situ imaging …

The Effects Of Writing Groups On Student Self-Efficacy, Katie Francom

Theses and Dissertations

High school students often lack confidence in their writing. One way to change this is by increasing their self-efficacy regarding writing. Previous studies suggest that writing groups have effectively improved students' self-efficacy in higher education. However, more must be done to see if this same intervention would succeed in high school. This study aimed to test this hypothesis and answer the question: How does participating in writing groups shape adolescents' writing self-efficacy? To do this, 57 11th-grade students participated in writing groups in an Honors English 11 class over a semester. For the study, they were surveyed about their writerly …

Automated Data-Flow Optimization For Digital Signal Processors, Madushan Thilina Abeysinghe

Theses and Dissertations

Digital signal processors (DSP), which are characterized by statically-scheduled Very-Long Instruction Word architectures and software-defined scratchpad memory, are currently the go-to processor type for low-power embedded vision systems, as exemplified by the DSP processors integrated into systems-on-chips from NVIDIA, Samsung, Qualcomm, Apple, and Texas Instruments. DSPs achieve performance by statically scheduling workloads, both in terms of data movement and instructions. We developed a method for scheduling buffer transactions across a data flow graph using data-driven performance models, yielding a 25% average reduction in execution time and a reduction of up to 85% DRAM utilization for randomly-generated data flow graphs. We …

Further study is needed to determine evolving needs and best practices for increasing the academic achievement for this population. Some possible solutions to Latinx students falling behind their hegemonic peers include incorporating Latinx culture in curriculum and school culture, as well …

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 …

Development Of Dip-Coated Carbon Fibers For Structural Power Composites And Optimization Of Bus Plates For Passively Propagation Resistant Batteries, David Petrushenko

Theses and Dissertations

Increasing demand for lithium-ion batteries in electric vehicles, portable electronics, and electric aircraft is a driving force for the expansion in new battery architectures to achieve higher gravimetric and volumetric efficiencies. In practice, maximizing energy density can be achieved by introducing state-of-the-art materials to increase the capacity of cells or by reducing the system's mass by incorporating lightweight structural materials. An alternative approach is to develop systems capable of performing multiple functions simultaneously that combine mono-functions of the battery and vehicular structure in a multifunctional component capable of storing electrical energy and providing structural support.

The initial focus of this …

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 …

Simultaneous Crack & Wave Propagation And Acoustic Emission Signal Modelling Using Peri-Elastodynamic, Md Mushfiqur Rahman Fahim

Enhancing Surface Texturing Of Zirconia Toughened Alumina Ceramic Through Optimized Electric Discharge Machining Utilizing The Assistive Electrode Method, Yazan Eyas Tuffaha

Theses and Dissertations

Zirconia toughened alumina (ZTA) is a durable and biocompatible ceramic material commonly used in prosthetic hip implants because of its excellent mechanical properties and wear/corrosion resistance. Surface texturing can improve the lubricity and longevity of hip implant bearing surfaces, but precision machining of ceramic materials such as ZTA is very difficult due to suboptimal surface integrity results of traditional machining techniques. This thesis explores the optimization of machining ZTA using electric discharge machining (EDM) - a process usually reserved for conductive metals - to machine holes into the ceramic to create surface textures. EDM is made possible through the assistive …

Implicit Vs. Explicit Approaches When Teaching Reflexive Structures In A Fifth-Grade Spanish Dual Immersion Classroom, Paula Valeria Ward

Theses and Dissertations

Dual language immersion (DLI) students can develop high levels of proficiency in their second language at a young age. However, they often have difficulties with their accuracy using advanced grammatical constructions (Watzinger-Tharp et al., 2018), such as using different verbs tenses or gender and number agreement in speaking and writing (Bateman et al., 2020). The goal of this study is to test whether explicit or implicit instructional approaches are more effective in the teaching of one such grammatical concept, specifically reflexive constructions, in two DLI classrooms. In this research, I investigated results from a five-lesson treatment in a case study …

Reconstructing Visual Narratives: Mary Colter, Fred Kabotie, And The Myth Of The West At Desert View Watchtower, Allison M. Foster

Theses and Dissertations

Desert View Watchtower opened in 1933 on the Grand Canyon South Rim, under the management of the Fred Harvey Company. The structure contains many self-contradictions, in terms of style and use. In this thesis, I argue that these contradictions come from the dichotomous motives of Desert View Watchtower's architect, Mary Colter, and her employers, the Fred Harvey Company and the Atchison, Topeka & Santa Fe Railway. New western history theory of the Mythical West is used to explain Harvey/Santa Fe marketing, which created a narrative suggesting that Native American lifeways were going to disappear from the Southwest. I argue that …

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 …

Medieval To Modern: Morgan Le Fay As Folk Icon Of Women In Power In Modern King Arthur Stories, Colleen Victoria Etman

Theses and Dissertations

This dissertation interrogates the ways that society views women with/in power through Arthurian adaptation. The body of work that makes up the Arthurian story is a sort of folk legend, a myth being told and retold by various authors in their own way. By using folk studies to analyze both medieval and modern texts, we can dissect what is important enough to remain over time. This signifies cultural values; things that have remained over time are reflective of the values of the writers producing these works, as well as the audiences consuming them. By interrogating these stories, we can make …

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 = …

Investigating Arctic Ocean Freshwater Content And Circulation In A Changing Climate, Emma Louise Hoffman

Theses and Dissertations

The Arctic Ocean is unique among the world’s oceans, characterized by its cold temperatures, salinity-driven vertical structure, and shallow shelf seas. It has warmed intensely since the 1980s at rates exceeding the global average. This Arctic Amplification drives variability in sea ice and salinity, affecting local circulation and exchange with other basins, leading to global changes in oceanic and atmospheric circulation and the biosphere. This thesis explores changing dynamics in the Arctic Ocean, in particular connecting modeled changes in liquid freshwater content (FWC) and its pathways with major ocean circulation patterns, atmospheric drivers, and large-scale climatic changes.

This research combines …

Detection And Analysis Of Solid-Phase Nutrients In Complex Benthic Cyanobacterium Communities, Cassidy Ann Crandell

Theses and Dissertations

Eutrophication is one of the most serious water quality issues affecting aquatic systems in the United States. Densely populated urban areas as well as mining and agriculture are major sources of anthropogenic nutrient loading into lakes and rivers. Excess loading of nutrients like phosphorus (P) into these ecosystems can cause native algal species to be outcompeted by harmful algal bloom (HAB) species. Increases in these HAB events are a growing public health concern as contact with excreted toxins can be harmful for human, aquatic, and land species. Remediation techniques like total maximum daily loads (TMDLs) have been implemented to reduce …

South Carolina School District Takeover: A Critical Policy Analysis, David Osworth

Theses and Dissertations

School takeover is a reform strategy where a school or district is placed into the control of a state or municipal government agency. Takeover has become increasingly popular in many states as an attempt to improve schools and district that are struggling either academically or financially. Takeover, however, is more likely to be implemented in districts serving a higher proportion of Black students. Due to the racialized nature of this policy this study uses a Critical Race Theory (CRT) methodology to engage in a critical policy analysis of school takeover in one rural school district in South Carolina. This study …
