Pop Gugak And E-Sang: Negotiating Traditional And Pop Genre Categories In Expressions Of Identity, Jessica Ellis Aug 2023

Pop Gugak And E-Sang: Negotiating Traditional And Pop Genre Categories In Expressions Of Identity, Jessica Ellis

Theses and Dissertations

Korean traditional music has a popularity problem among Korea's contemporary audiences; given the choice of what to listen to, few South Koreans choose to listen to gugak. To address and overcome this popularity problem, traditional Korean musicians are negotiating and reconstructing traditional Korean music by adopting, appropriating, and altering elements of Korean and international pop music. To this end, Gugak groups recently have been incorporating western musical practices and aesthetics in their performances in digital platforms (YouTube and reality television programs) and in concerts to contemporize the genre and develop a more positive relationship between Koreans and their national music. …

Gene Dive: Assessing The Diversity Of Perchlorate Reducing Genes In Mars Analog Environments, Colin Michael Robinson Aug 2023

Gene Dive: Assessing The Diversity Of Perchlorate Reducing Genes In Mars Analog Environments, Colin Michael Robinson

Theses and Dissertations

Biotic perchlorate reduction, a metabolic process that potentially occurs on Mars, has long been the subject of speculation in astrobiology. To determine whether it could be a viable metabolic strategy on the Red Planet, we sought to determine whether biotic perchlorate reduction could evolve and persist in Mars-analog environments on Earth. In this study, we introduce Gene Dive, a novel computational methodology that leverages profile hidden Markov models, sequence alignment, phylogenetic tree construction, and Faith's phylogenetic diversity to probe the prevalence and diversity of perchlorate reducing genes in metagenomes. To determine whether biotic perchlorate reduction persists in a wide range …

Enhanced Capabilities For Investigating Local Structure And Magnetism: Three Dimensional Magnetic Pair Distribution Function And Symmetry Mode Analysis, Parker Hamilton Aug 2023

Enhanced Capabilities For Investigating Local Structure And Magnetism: Three Dimensional Magnetic Pair Distribution Function And Symmetry Mode Analysis, Parker Hamilton

Theses and Dissertations

The local structure, atomic and magnetic structure correlated over a small length scale, of a material has a strong impact on material properties. Pair distribution function (PDF) analysis is a strong tool to investigate local structure and magnetism of this nature. This work outlines extensions to current one dimensional magnetic pair distribution functions (1D-mPDF) and the fitting of structures with symmetry breaking local atomic distortions. 1DmPDF analysis has been used to study local magnetic structure, but requires a rotational averaging of the correlations so directional information is lost, as in powder diffraction experiments. Three dimensional difference magnetic pair distribution function …

A Colorfully Natural Twin Higgs Model, Logan Coleman Page Aug 2023

A Colorfully Natural Twin Higgs Model, Logan Coleman Page

Theses and Dissertations

Twin Higgs models have the potential to explain phenomena outside of the Standard Model and provide an natural explanation of the Higgs mass. Here I explore a new realization of the twin Higgs concept with an SU(4)c symmetry that is spontaneously broken in the Standard Model sector, but remains unbroken in the Twin sector. I detail the phenomenological results produced by this model. I show that this construction leads to a qualitatively new behavior regarding the fine-tuning of the Higgs mass due to the top-quark sector.

Constructing Stellar Mass Models For Early-Type Galaxies With Circumnuclear Disks, Jared R. Davidson Aug 2023

Constructing Stellar Mass Models For Early-Type Galaxies With Circumnuclear Disks, Jared R. Davidson

Theses and Dissertations

Dusty circumnuclear disks (CNDs) in luminous early-type galaxies (ETGs) show regular, dynamically cold molecular gas kinematics. For a growing number of these ETGs, Atacama Large Millimeter/sub-millimeter Array (ALMA) CO imaging and detailed gas-dynamical modeling have yielded moderate to high precision black hole (BH) mass (M_BH) determinations. To date, however, few studies have explored the effects of dust attenuation, or uncertainties in dust corrections, on recovered stellar luminosity models from high angular resolution optical/near-IR observations and M_BH measurements. Recent kinematic studies that modeled ALMA CO data sets have found that uncertainties in the intrinsic central stellar surface brightness slope due to …

"The Trees Act Not As Individuals"--Learning To See The Whole Picture In Biology Education And Remote Sensing Research, Rebeka A.F. Greenall

Theses and Dissertations

To increase equity and inclusion for underserved and excluded Indigenous students, we must make efforts to mitigate the unique barriers they face. As their knowledge systems have been historically excluded and erased in Western science, we begin by reviewing the literature on the inclusion of Traditional Ecological Knowledge (TEK) in biology education and describe best practices. Next, to better understand how Native Hawaiian and other Pacific Islander (NHPI) students integrate into the scientific community, we used Social Influence Theory as a framework to measure NHPI student science identity, self-efficacy, alignment with science values, and belonging. We also investigated how students …

Phosphorus Sorption And Kinetics Across The Sediment-Water Interface Of Utah Lake, A Shallow Eutrophic Lake, Forrest Fielding Stretch Jarvis Jarvis Aug 2023

Phosphorus Sorption And Kinetics Across The Sediment-Water Interface Of Utah Lake, A Shallow Eutrophic Lake, Forrest Fielding Stretch Jarvis Jarvis

Theses and Dissertations

Internal sediment phosphorus (P) cycling may regulate harmful algal blooms (HABs) in shallow eutrophic lakes. Utah Lake frequently experiences HABs despite its high alkalinity and P-rich sediment. Phosphorus cycling between the lakebed and the water column is dependent upon stable P-sorption with organic matter (OM) and mineral species, which can vary with substrate availability, P-concentrations, temperature, redox, pH, and microbial activity. A full biogeochemical analysis of the water and sediment across seven sites shows Utah Lake to be spatially well-mixed in terms of composition and sorption, with few exceptions. Sediment P-concentrations (avg. 677 mg-P kg-1) primarily correlate with redox-sensitive iron …

Parental Roles In K-12 Online Education, Barbara Tanner Sandberg Aug 2023

Parental Roles In K-12 Online Education, Barbara Tanner Sandberg

Theses and Dissertations

Parental support roles in K-12 online learning differ from traditional schools. Since K-12 students typically have not developed the self-regulation skills necessary for academic engagement, parents partner with schools to provide the affective, behavioral, and cognitive engagement support necessary for academic success. Through 21 semistructured interviews with parents supporting K-12 students in varied online contexts, this study delineates how parents provided support in each of these dimensions of engagement. The participants felt that in online education, parents should take the primary responsibility for behavioral engagement support, and that teachers were primarily responsible for cognitive support. Parents believed they shared affective …

Food Web Of Icy Strait, Alaska: Comparison Of Position, Size, And Overlap Of Trophic Niche Among Fish Species, Andrew D. Suchomel

Theses and Dissertations

The Icy Strait of southeast Alaska, USA is an ideal system to study how ecological diversity is maintained. This area has historical ecological significance and supports diverse assemblages of fish species that are easily sampled. We used stable isotope analysis using δ13C and δ15N stable isotope ratios. Using these isotope ratios, we quantified trophic niche position, size, and overlap and compared how those trophic niche metrics varied using ecological and evolutionary perspectives. For ecological variation, mean total length, and δ13C trophic niche position has positive relationships with trophic niche size while total percent trophic niche overlap had a strong negative …

Preparing For V2x Deployment: Evaluating Current Anonymity Implementations, And Developing A Framework For Gauging Roadside Unit Networkability, Daniel Arnaudov Sharp Aug 2023

Preparing For V2x Deployment: Evaluating Current Anonymity Implementations, And Developing A Framework For Gauging Roadside Unit Networkability, Daniel Arnaudov Sharp

Theses and Dissertations

In this thesis we answer two questions relating to the impending deployment of V2X. We answer, "What is the state of current privacy measures implemented to prevent tracking and promote anonymity?" We answer this by showing that tracking methods used to circumvent changing IDs are possible. We also show through conservative calculations that this problem will not go away on its own and requires direct effort. We also answer, "Is the available production V2X hardware ready for scalable deployment?" To do this we develop a framework for evaluating RSUs and many of their core functions related to deployment, scalability, and …

Designed For Better Control: Using Kinematic And Dynamic Metrics To Optimize Robot Manipulator Design, John R. Morrell Aug 2023

Designed For Better Control: Using Kinematic And Dynamic Metrics To Optimize Robot Manipulator Design, John R. Morrell

Theses and Dissertations

In the field of control theory, optimal performance is generally defined as the best possible controlled performance given a static, unchangeable plant system. However, principled design of the underlying system can make designing effective controllers easier and dramatically improve the final control performance beyond what any finely tuned controller could achieve alone. This work develops performance metrics for serial robot arms which help guide the design and optimization of the structure of the arm to achieve greater final performance. First, a kinematic (motion-based) metric called the Actuator Independence Metric (AIM) measures the uniqueness of the movement capabilities of the different …

Measuring Microparticle Adhesion Via High-Speed Rotor, Jacob C. Fearnley Aug 2023

Measuring Microparticle Adhesion Via High-Speed Rotor, Jacob C. Fearnley

Theses and Dissertations

Much is known about the atomic/molecular theories that govern adhesion as well as the macroscopic aspects and properties of adhesion. However, adhesion in the microparticle regime is poorly characterized. We report on experiments that use centrifugal force to remove polystyrene (PS) particles from the surface of a high-speed titanium rotor operated in vacuum. This unique rotor can apply forces far greater than other centrifugal force methods or related techniques using atomic force spectroscopy. The mode of attachment, whether particles were located on the windward side versus leeward side of the spinning rotor, time spent in vacuum prior to experiments, and …

Detailed Characterization Of Material Deformation, Alexander J. Farnsworth Aug 2023

Detailed Characterization Of Material Deformation, Alexander J. Farnsworth

Theses and Dissertations

This dissertation presents a comprehensive exploration of material deformation at the atomic level, investigating key findings and contributions through three fundamental methods: Sum Frequency Generation Spectroscopy (SFG), X-ray Diffraction (XRD), and Electron Backscatter Diffraction (EBSD). The research commences by uncovering the material dependency of nonresonant responses in both SFG and Second Harmonic Generation (SHG) signals. This redefinition of the nonresonant component as an information-rich carrier, rather than mere background noise, leads to novel insights into the potential applications of SFG. The study then delves further into the influence of mechanical stress on materials, establishing a connection between dislocation density on …

“Já Muito Estropeadas”: Bodies And Landscapes Of Oppression In Rodolfo Teófilo’S A Fome, Mikaela Wood Aug 2023

“Já Muito Estropeadas”: Bodies And Landscapes Of Oppression In Rodolfo Teófilo’S A Fome, Mikaela Wood

Theses and Dissertations

This thesis article analyzes Rodolfo Teófilo's novel "A fome" through the lens of ecofeminism, exploring the representations of gender and nature in Brazilian literature. The novel, set during a devastating drought in the Northeast, follows Manuel de Freitas and his family as they seek relief in Ceará. While existing criticism has focused on the novel's use of nature and masculinity, the portrayal of female characters and the connection between gender and nature representations have been overlooked. Ecofeminist theory offers a critical perspective to understand these dynamics, revealing the devaluation of women and nature in favor of men and human beings …

Interaction Of Natural Convection And Real Gas Radiation Over A Vertical Flat Plate, Nathan Hale Aug 2023

Interaction Of Natural Convection And Real Gas Radiation Over A Vertical Flat Plate, Nathan Hale

Theses and Dissertations

This study explores natural convection heat transfer and fluid flow from a vertical plate in a radiating gas accounting for real gas spectral behavior. Finite volume techniques are used to solve the coupled nonlinear partial differential equations for mass, momentum, and energy conservation, while radiation transfer is modeled using the Discrete Ordinates finite volume finite angle method. Real gas spectral behavior is accounted for using the Rank Correlated Spectral Line Weighted-sum-of-gray-gases method. It is found that gas temperature and velocity are higher in the boundary layer, thickening the thermal and hydrodynamic boundary layers compared to the limiting case of pure …

Soil Seed Bank Composition And Spatial Distribution In A Cheatgrass (Bromus Tectorum L.)–Dominated Rangeland In Colorado, Usa, Ryan W. R. Schroeder, Jayne L. Jonas, M. Nikki Grant-Hoffman, Mark W. Paschke Aug 2023

Soil Seed Bank Composition And Spatial Distribution In A Cheatgrass (Bromus Tectorum L.)–Dominated Rangeland In Colorado, Usa, Ryan W. R. Schroeder, Jayne L. Jonas, M. Nikki Grant-Hoffman, Mark W. Paschke

Western North American Naturalist

Invasion by nonnative annual plants that form prolific seed banks, including Bromus tectorum L. (cheatgrass), throughout western North America is a major natural resource concern. Even with known economic and ecological implications, soil seed banks and their potential to impact ecological restoration in arid and semiarid ecosystems are poorly understood. Quantifying the regenerative potential of the soil seed bank—the living seeds in the soil profile and on the soil surface—can help natural resource managers make decisions to increase the likelihood of restoration success. We analyzed the germinable soil seed bank composition and distribution of a rangeland site in western Colorado …

Groundwater Resource Assessment For West Africa Using Earth Observations And Groundwater Modeling, Sergio Armando Barbosa Casas Aug 2023

Groundwater Resource Assessment For West Africa Using Earth Observations And Groundwater Modeling, Sergio Armando Barbosa Casas

Theses and Dissertations

Groundwater is a crucial global resource, particularly in semiarid regions where surface water is scarce. As a result, effective groundwater management is essential. However, the challenge lies in a lack of data and information for proper decision-making. This dissertation present studies related to groundwater storage changes and recharge in West Africa, using data from NASA's Gravity Recovery and Climate Experiment (GRACE) mission. In Niger, this research reveals little change in groundwater storage from 2002 to 2010 but a steep rise from 2010 to 2021, attributed partially to increased precipitation. Groundwater resources in Niger are found to be underutilized, with estimated …
