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 …

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 …

Classifying Floor Accelerations For Gait Estimation And Detection, Jean Michel Franco Lozada

Theses and Dissertations

Structural vibrations are traditionally used to learn about structural systems, such as determining the dynamic characteristics of a structure and evaluating its structural performance under certain dynamic loads. Recently, researchers have proposed the use of structural vibrations to know more about the occupants of the structure in addition to the structure itself. One example of such would be to determine when a person falls, or to identify the location of a person walking in a building. Using structural vibrations to study occupants can be directly applicable to many fields, ranging from healthcare to security applications. One powerful use of structural …

Tax Client Goals, Regulatory Pressure, And Professional Decision-Making, Spenser G. Seifert

Theses and Dissertations

Drawing on goal theory, I illuminate how client preferences become internalized goals for tax professionals and how these client goals influence the motivated reasoning and ultimate decision-making of tax professionals. Using this theoretical framework, I then utilize an experiment to explore how the presence of salient situational factors – goal specificity, goal progress, and regulatory pressure – influence tax professionals’ decision-making. The results suggest that, as a result of their roles as both client advocates and CPAs, tax professionals default to non-specific “do your best” goals regardless of client preference specificity. Additionally, I find that increased regulatory pressure may curb …

Bass-Triadic Cadence Formulae In Melchior Neusidler’S Original Compositions From Il Primo (-Secondo) Intabolatura Di Liuto, Christopher Mcdonald

Theses and Dissertations

There was a paradigmatic shift in the discourse surrounding lute music between the early sixteenth and seventeenth centuries. The lute treatises written by early sixteenth-century German lutenists, such as Hans Judenkünig, Hanse Gerle, and Hans Newsidler, focused on technical directives that support a linear conception of music. However, lutenists active in the late sixteenth and early seventeenth century, such as Matthaeus Waissel and Jean-Baptiste Besard, describe technical accommodations for vertically conceived structures. Contemporaneously, at the turn of the seventeenth century, the discourse on bass primacy and triadic structures developed from an undercurrent, cast in the shadow of counterpoint treatises, to …

Businesses Or Beneficiaries: The Submerged Consequences Of Workfare Policy Design, Morgan Alexander Lowder

Theses and Dissertations

This dissertation critically analyzes the policy association between the Supplemental Nutrition Assistance Program (SNAP) and the Work Opportunity Tax Credit (WOTC), and in doing so, sheds light on the employer-uplifting design of the U.S. welfare state. I examine this association in three stand-alone Chapters with the intent of answering the following questions: 1) Is the SNAP-WOTC association mutually beneficial to SNAP recipients and the employers that access the WOTC; 2) Is the SNAP-WOTC association truly intended to be mutually beneficial; and 3) What are the perceptive consequences of revealing how SNAP benefits employers through the WOTC. Using both quantitative and …

Bayesian Methods In Analyzing The Diagnostic Accuracy\\ For Ordinal Ratings, Yun Yang

Theses and Dissertations

This dissertation focuses on ordinal classification ratings, which are commonly used in medical practice to assess the severity of a disease or condition. For example, a group of radiologists rate a set of mammograms and assign BI-RADS (Breast Imaging Reporting Data System) score for each mammogram. A Bayesian probit hierarchical model is first proposed to analyze this type of data. It links the ordinal ratings with both rater diagnostic skills and patient latent disease severity. Each rater diagnostic skills are quantified with two parameters, diagnostic bias and diagnostic magnifier. Patient latent disease severity is assumed to follow a different normal …

Exploring Heat Variations In Columbia, South Carolina, Michael Graeme Hohlfeld

Theses and Dissertations

As the leading cause of weather-related fatalities in the United States, the concept of heat as a hazard has been studied for decades, especially in the urban environment. Urban heat island research is limited by the fact that most investigate land surface temperature rather than air temperature and other variables that affect human comfort including humidity. This thesis utilizes a public network of weather stations in Richland County, South Carolina to investigate differences in heat between the city of Columbia, and more rural parts of the county. The study period was June, July, and August of 2022. Results indicate that …

Generalizations Of The Graham-Pollak Tree Theorem, Gabrielle Anne Tauscheck

Theses and Dissertations

Graham and Pollak showed in 1971 that the determinant of a tree’s distance matrix depends only on its number of vertices, and, in particular, it is always nonzero. This dissertation will generalize their result via two different directions: Steiner distance k-matrices and distance critical graphs. The Steiner distance of a collection of k vertices in a graph is the fewest number of edges in any connected subgraph containing those vertices; for k = 2, this reduces to the ordinary definition of graphical distance. Here, we show that the hyperdeterminant of the Steiner distance k-matrix is always zero if …

Microchannel Slip Flow Characteristics By Time Travel After Photobleaching Velocimetry, Brandon James Sellers

Theses and Dissertations

Interfacial science follows the study of observing behavior between two or more phases of matter when in contact. For example, a liquid solution passes through a microchannel, and the walls interact with the fluid shearing along the surface. The fluid particles develop momentum changes from interfacial phenomena and slip along the wall begins to affect the fluid body. Slip flow is a name for the phenomenon, and with it, modeling velocity for the interfacial behavior demands both resolution and minimal interference. Laser-induced fluorescence photobleaching anemometry (LIFPA) works as a sound method for acquiring data on microchannel flow, but it needed …

Representation Dimensions Of Algebraic Tori And Symmetric Ranks Of G-Lattices, Jason Bailey Heath

Theses and Dissertations

Algebraic tori over a field k are special examples of affine group schemes over k, such as the multiplicative group of the field or the unit circle. Any algebraic torus can be embedded into the group of invertible n x n matrices with entries in k for some n, and the smallest such n is called the representation dimension of that torus. Representation dimensions of algebraic tori can be studied via symmetric ranks of G-lattices. A G-lattice L is a group isomorphic to the additive group Zⁿ for some n, along with an action …

Using Landscape Archaeology To Gain Insight Into The Human Experience During The Late Woodland And Mississippian Periods In South Carolina’S Pee Dee River Basin, Noah Safari

Theses and Dissertations

People move through and use the landscape in the ways they do for myriad reasons. The goal of this thesis was to elucidate how people viewed and settled in the Pee Dee River Basin area during the Late Woodland and Mississippian Periods in South Carolina. Framing my research with a landscape archaeology focus, by considering sites within a larger region or landscape, we can inhabit the “taskscapes” of the past and gain an understanding of the past (Ingold 1993).

To do this, I used the methodological lens of settlement ecology “to build a balance sheet of varying priorities (Stone 1996:8) …

“That Desolate Section Of Dixiecrats And Hookworms”: The Rise And Fall Of The Cio In Sumter, South Carolina, 1927-1950, Stephen Malenowski

Theses and Dissertations

In March of 1942, the Williams Furniture Company of Sumter, South Carolina signed the first union contract in Sumter County history, the Congress of Industrial Organization’s (CIO) United Furniture Workers of America Local 273. This contract provided the CIO with one of their largest victories in all of South Carolina and helped create a sense of hope that the CIO could win organizing battles in South Carolina. Despite the optimism, unionization failed to spread across Sumter County during the postwar Operation Dixie organizing campaign. This thesis looks to answer why the Southern drive failed in Sumter. Local 273 did not …

The Effect Of Chromium Coatings On Hydrogen Uptake In Zirconium Alloy Nuclear Fuel Cladding, Jorie Lyn Walters

Theses and Dissertations

The amount of hydrogen in a nuclear reactor can have a profound impact on its performance and safety when it is absorbed into or released from fuel rods. Hydrogen pickup in modern fuel cladding materials has been minimized by alloying additions and microstructural texture engineering, but these materials are still susceptible to hydrogen release during high temperature oxidation. The nuclear accident at the Fukushima Daiichi power plant in 2011 resulted in hydrogen gas production and subsequent explosions which led the United States Department of Energy to initiate a program to develop enhanced nuclear fuel cladding materials. New cladding materials include …

(Re)Imagining Decolonial Cookbooks After Deforestation, Kamran Shams

Theses and Dissertations

Food, like most else, is fundamentally changed by colonization. It is not just the aftermath of colonization, the settlement, that changes food—it is the act of colonial infiltrating itself. Such is the case made by Fernando Ismael Quiñones Valdivia in “Colonial Imaginations: Solitude in the Cartas y Relaciones of Hernán Cortés”—though not for food but for colonized societies broadly. More specifically, he contends that a new epistemological possibility arises when colonizer regards land as an object to be conquered, which precedes the epistemological articulation of subject/object divide. His article supplies a framework for thinking about coloniality so that a close …

Metal-Organic Frameworks For Global Environmental Challenges, Kyoungchul Park

Theses and Dissertations

Over the past few decades, there has been a demand for improving nuclear waste administration due to a significant increase in the utilization of nuclear energy. The driving force for proper nuclear waste disposal is evident when considering past nuclear catastrophes—such as Chernobyl and Fukushima—where radionuclide contamination of large bodies of water sparked public concern. In order to manage such radioactive species, the emerging areas of radionuclide sequestration, storage, separation, and sensing must be addressed in the upcoming years. This dissertation presents a potential candidate for addressing these challenges, called metal-organic frameworks (MOFs). Due to their porosity, high surface area, …
