This study aimed to analyze the risk factors for reoperation after operative fixation of these fractures. Methods: This was an institional review board (IRB) approved retrospective study of extra-articuilar, partial articular, and complete articular distal femur fractures treated with operative fixation at a Level I trauma center between 2008 and 2018. The study included a consecutive series of adult patients operatively treated for a distal femur fracture. The primary outcome was reoperation rate due to infection, non-union, or implant failure. Periprosthetic …

Rock Climbing And Conservation In Land Management: Can They Coexist?, Marissa Heller

Geography ETDs

As participation in outdoor recreation is growing in the U.S., a dilemma is presented for conservation planners and land area managers who must manage the increasing demand for recreation while simultaneously working to protect species. Rock climbers and other outdoor recreationalists have asserted that a relationship exists between recreation and the conservation of public lands. However, mounting evidence suggests that rock climbing continues to cause a multitude of negative impacts to ecosystems. Here, I investigate the extent to which land management practices allow for rock climbing and conservation to coexist, and how it is that well developed plans protect ecologically …

The Health And Socioeconomic Burdens Of Air Pollution And Public Preference For Air Quality Improvement, Niraj Khatiwada

Economics ETDs

This dissertation consists of five chapters on air pollution. Chapter 1 discusses the issue of air pollution in two regions in South Asia: the Hindu-Kush Himalayan (HKH) Region and the Indo-Gangetic Plain (IGP). Chapter 2 builds on the canonical health production function model to investigate the heterogeneity in air pollution exposure and health outcome using data from Siddharthanagar municipality of Nepal. I use a novel approach of directly measuring individual lung functions to assess respiratory health conditions. The findings reveal lower lung functions among outdoor workers and individuals from households residing near prominent local pollution sources. The use of exposure …

Alterations In Executive Functioning Following Moderate Prenatal Alcohol Exposure: New Translational Insights, Sarah L. Olguin

Biomedical Sciences ETDs

While the lifelong difficulties that result from alcohol exposure in utero are well documented, Fetal Alcohol Spectrum Disorders (FASD) remain the most common neurodevelopmental syndrome. FASD patients struggle with executive control including attention, cognitive control, reward learning, and impulsivity. These self-regulation problems contribute to increased rates of school expulsion, incarceration, and substance use disorders. However, it is still unclear how prenatal alcohol exposure (PAE) affects executive control processes that lead to inappropriate behavior later in life. Here we examined the effect of PAE on 4 aspects of executive functioning paired with intervention or with translatable EEG-like recording, 1) control over …

Olfactory Detection Of Viruses Shapes Brain Immunity And Behavior, Aurora Kraus

Biology ETDs

Olfactory sensory neurons (OSNs) directly contact the environment and are

exposed to pathogens, such as viruses. When OSNs detect a virus, they coordinate antiviral immune responses locally to stop virus progression into the brain, termed the central nervous system (CNS). For example, in COVID-19 patients the SARS-CoV-2 virus replicates in the olfactory epithelium resulting in loss of olfaction, yet viral presence in the CNS is rare. However, neuronal detection of a virus by OSNs may send electrical signals to the CNS via the olfactory bulb (OB) and shape our CNS. Because the OB is the nexus between the pathogen exposed …

A Theory Of Text Setting Contour: A Proposed Theory That Places Text At The Structural Foreground Of The Analysis Of Vocal Music, Grace K. Weaver

Music ETDs

How can contour theory be used to analyze a composer’s setting of a poem? Can this approach provide insights that lead to an interpretation of the composer’s setting of the text? This study presents a new contour theory on text setting by examining two different settings of the same text. This theory examines one aspect of the music, the vocal line, and plots syllable’s locations in two dimensions of music: pitch space and duration. Using these data points, one can suggest an interpretation of the poem. Through the application of this theory to Fanny Hensel and Franz Schubert’s setting of …

Physiologically-Based Pharmacokinetics Modeling Of Colloidal Nanoparticles, Anh-Dung Le

Nanoscience and Microsystems ETDs

Physiologically-based Pharmacokinetics (PBPK) modeling—a mechanistic mathematical tool to predict biodistribution to inform drug development, requires knowledge of the physico-chemical properties of the drug in question as well as the anatomy and physiology of the organism. Unlike with molecular drugs, nanoparticle parameters often need to be estimated by fitting models to time-course data, which can result in large uncertainties in parameter estimates due to a high-dimensional parameter space. Our research addresses this challenge by offering a path to parameter insights using global sensitivity analysis. The first chapter is an overview of the PBPK model structure and mathematical framework used in our …

Interfacial Interactions Of Uranium And Hdpe In Agricultural Soil And Their Bioacummulation In Mentha Arvensis, Casey Miller, Andrew Neidhart, Kendra Hess, Abdul-Mehdi S. Ali, Angelica Benavidez, Michael Spilde, Laura Green, José M. Cerrato, Jorge Gonzalez Estrella, Eliane El Hayek

Civil Engineering ETDs

We investigated the adsorption, precipitation, and phytoavailability of uranium after reactions with soil, high-density polyethylene particles, and Mentha arvensis through the integration of batch experiments, plant exposure, microscopy, and spectroscopy. Soluble U (initially 100 µM) decreased by 98.6% (1.09 µM) at pH 5 and 86.2% (13.81 µM) at pH 7.5 after 0.1 h of reaction with 10 g of soil in solution. Heterogenous U precipitates were observed in weathered HDPE surfaces for experiments without soil at both pH conditions. This suggests the weathering of the microplastic surfaces enhanced the nucleation of the U precipitates. Plants exposed to both U and …

Heat Stress And The Control Of Skeletal Muscle Mass, Zachary J. Fennel

Health, Exercise, and Sports Sciences ETDs

PURPOSE: 1) Compare the effects of whole-body heat stress (HS) and resistance exercise (RE) on thermoregulatory responses and skeletal muscle heat shock and hypertrophy related signaling. 2) Examine the effects of acute heat stress (HEAT) on myotube growth and fusion compared to controls (CON), hypertrophy (HYPER), and atrophy (RAPA) treatments in-vitro. METHODS: 1) Eight healthy, physically active and resistance trained individuals (18-45 years) completed RE and HS. 2) 48 hours following treatments, C2C12 myotubes were assessed for myotube area and nuclear fusion index. RESULTS: 1) RE and HS similarly increased muscle but not core temperatures. HS but not RE increased …

Rapid Response Protocol (Rrp) For Monitoring Water Quality Parameters For Wildfire Disturbance, Paige G. Tunby

Civil Engineering ETDs

The increase in wildfire frequency and intensity has been driven by the sensitivity of fire regimes to climate changes and fire suppression. Wildfires impact hydrological and environmental processes and ecosystem service due to the mobilization of wildfire debris by precipitation. Data on post-fire water quality dynamics have been measured in a few study cases from burned watersheds where sensors were deployed to monitor non-fire-related water quality issues. This has led to a dearth of data for understanding the effects of wildfire disturbances on fluvial networks. To close the gap in available water quality data, we have created a rapid response …

Heterogeneity Of Gene Trees, Jonathan Nenye Odumegwu Unm

Mathematics & Statistics ETDs

Multilocus phylogenetic studies often show a high degree of gene tree heterogeneity —gene trees that have different topologies from each other as well as from the species tree topology. In some cases, this can lead to studies with hundreds of loci having distinct gene tree topologies. The degree of heterogeneity is expected to increase when there is a high degree of incomplete lineage sorting due to short branches (as measured in coalescent units) in the species tree. Other potential sources of heterogeneity include other biological processes such as introgression, recombination within genes, ancestral population structure, gene duplication and loss, and …

The Political Urgency Of Black Manhood: Frederick Douglass On Constitutional Theory, John M. Kang

Faculty Scholarship

How did Frederick Douglass—one who was born a slave, one who had been denied all formal education, one who had been sundered from his family, one who had been starved, tortured, and, on occasion, nearly killed—manage to muster the courage to do something as bold as challenge the United States Supreme Court? This Article suggests that Douglass, in order to assert his right as an American citizen, first had to assert his right as a man in an explicitly gendered sense. That is, Douglass had to muster a powerful sense of manliness that could elevate him psychologically to assert his …

Using Insurance To Regulate Food Safety: Field Notes From The Food Produce Sector, Timothy D. Lytton

New Mexico Law Review

Foodborne illness is a public health problem of pandemic proportions. In the United States alone, contaminated food sickens an estimated 48 million consumers annually, causing 128,000 hospitalizations and 3,000 deaths. Nowhere is this crisis more acute than in the fresh produce sector, where microbial contamination in growing fields and packing houses has been responsible for many of the nation’s largest and deadliest outbreaks.

This Article examines emerging efforts by private insurance companies to regulate food safety on farms that grow fresh produce.

Previous studies of using insurance to regulate food safety rely on economic theories that yield competing conclusions. Optimists …

The Bluff And Blanding Fights: Race, Religion, And Settler Colonialism In Progressive-Era America, Reilly Ben Hatch

History ETDs

This project uses the Bluff War of 1915 and the Posey War of 1923—both of which took place in southeastern Utah—to look at the complex relationship between race, religion, and culture in American Indian policy at the beginning of the twentieth century. It shows how White Mesa Utes, local Mormon settlers, the federal government, and Progressive activists used the conflicts to argue the place of Indians in a “frontier-less” America. It also examines the complex relationship between Mormons and Indians and draws conclusions on how that relationship was influenced by an American government which sought to assimilate “others” into the …

Observational Constraints On The 520 Km Mantle Discontinuity, Mantle Transition Zone Anisotropy, And Local Seismicity At Mount St. Helens, Han Zhang

Earth and Planetary Sciences ETDs

Seismology provides valuable observational constraints to thermal and compositional states at inaccessible depths via understanding how elastic wave propagating through them. While many of fundament questions regarding solid Earth structures have been addressed during its more than 100 years history, some details remain unfilled and carefully designed approaches are needed to complete the pictures. This dissertation contributes observational constraints on three topics with newly developed methods. 1) We detected a controversial mantle discontinuity at about 520 km and concluded a mean mantle composition close to the Pyrolite model based on its seismic properties. 2) We isolated anisotropic effects in mantle …

Vulnerability, Invulnerability, And The Mechanism Of Disavowal, Mariah C. Partida

Philosophy ETDs

In this dissertation, I defend the view that, contrary to popular opinion, vulnerability is not merely susceptibility to harm but also openness to unanticipated change and transformation. Drawing on the work of Simone de Beauvoir, Judith Butler, Erinn Gilson, Gilles Deleuze, and Benedict Spinoza, I also aim to show that vulnerability is not a static property of some individuals but rather a relational process that is both universal and differently distributed. My original contribution to vulnerability studies is to trace the mechanism of disavowal across 20^th and 21^st century figures in philosophy: from Heidegger’s account of disavowing our …

Spirituality, Well-Being, And The Role Of Oneness, Kelly S. Erickson Albonico

Psychology ETDs

Spirituality is generally found to have a significant but small positive association with well-being; however, the associations between spirituality and well-being vary greatly. One organizing framework for understanding the varying associations may be the degree to which spirituality and well-being measures capture connection, the pinnacle of which may be conceptualized as Oneness. The purpose of this paper is twofold: to begin exploring this hypothesis by examining the associations between beliefs in Oneness and dimensions of subjective well-being and to test possible conflating and contributing factors in the associations between beliefs in Oneness and subjective well-being. Results indicated preliminary support for …

Longitudinal Manganese-Enhanced Magnetic Resonance Imaging Of Neural Projections And Activity, Taylor W. Uselman, Christopher S. Medina, Harry B. Gray, Russell E. Jacobs, Elaine L. Bearer

Pathology Research and Scholarship

Manganese-enhanced magnetic resonance imaging (MEMRI) holds exceptional promise for preclinical studies of brain-wide physiology in awake-behaving animals. The objectives of this review are to update the current information regarding MEMRI and to inform new investigators as to its potential. Mn(II) is a powerful contrast agent for two main reasons: (1) high signal intensity at low doses; and (2) biological interactions, such as projection tracing and neural activity mapping via entry into electrically active neurons in the living brain. High-spin Mn(II) reduces the relaxation time of water protons: at Mn(II) concentrations typically encountered in MEMRI, robust hyperintensity is obtained without adverse …

High Altitude Exposures And Intestinal Barrier Dysfunction, Zachary J. Mckenna

Health, Exercise, and Sports Sciences ETDs

Gastrointestinal complaints are often reported during high altitude ascent (>2500m), though their etiology is unknown. One explanation is hypoxia-mediated intestinal barrier dysfunction. High altitude exposures can result in splanchnic hypoperfusion and hypoxemia causing hypoxic and oxidative stress. Exertion may worsen hypoxia-induced intestinal injury via greater splanchnic hypoperfusion and hypoxemia. We propose that these stressors injure the intestinal barrier leading to increased permeability, bacterial translocation, and local/systemic inflammation which may contribute to gastrointestinal complications or Acute Mountain Sickness (AMS). To test this, we investigated the effects of hypoxia on exercise-induced gastrointestinal symptoms and markers of intestinal injury. Next, we determined …

Lecturas Ecoculturales Del Caribe Hispánico Y Francés Y Del Brasil, Mariana Herring

Spanish and Portuguese ETDs

In this dissertation, we analyze a selection of works, both literary and filmic, in order to explore how they connect ecological realities with the social, economic and cultural realms. Through the analysis of novels, biographies and films by Caribbean and Brazilian authors, this analysis will focus, in particular, on how these works show the impact of the imposition of the plantation, the modernization discourse, the ongoing colonial experience, and the dismissal of traditional and local knowledge and practices, on ecological problems in the past and in the present. By ecological, we do refer to the interconnectedness between the human and …

Thermoregulation And Spatial Distribution Of Lizards In The Southwestern Usa: Adaptation To A Changing Climate, Caleb Lee Loughran

Biology ETDs

Lizards rely heavily on environmental temperatures to thermoregulate and maintain a body temperature (Tb) that optimizes physiological function and maximizes surface activity time. While early research noted the propensity for lizards to thermoregulate by shuttling between different thermal environments, it was long assumed that evaporative cooling via panting was an ineffective means of thermoregulation. However, evaporative cooling can potentially lower a lizard’s Tb significantly below air temperature, and thus allow lizards to extend activity periods during prolonged heat exposure. In this dissertation, I explore the varying abilities of lizards to thermoregulate while panting. I describe the metabolic and evaporative water …

Fine-Mapping Of Human Antibody Specificity In Response To Natural Chlamydia Trachomatis Infection Utilized To Inform Vaccines Against Adhesion Factors, Amanda L. Collar

Biomedical Sciences ETDs

Chlamydia trachomatis (Ct) is the causative pathogen for the most common bacterial sexually transmitted infection worldwide and can cause serious medical consequences in women, including pelvic inflammatory disease, ectopic pregnancy, and infertility. For these reasons, a Ct vaccine is urgently needed, yet, its development remains a significant challenge. One barrier to producing a Ct vaccine is the gap in knowledge of protective immune responses for Ct infection, including the role that antibodies may play. Therefore, I aimed to characterize the human antibody response to natural urogenital Ct infection in women using Deep Sequence-Coupled Biopanning. Further, I leveraged these findings to …
