Methods For High-Dimensional Spatial Data: Dimension Reduction And Covariance Approximation, Paul May

Electronic Theses and Dissertations

In spatial statistics, because quantities are correlated based on their relative positions in space, data is modeled as a single realization of a multivariate stochastic process. Spatial data can be high-dimensional either through a large number of observed variables per location, or through a large number of observed locations. The two are often handled differently, with the former addressed through dimension reduction and the latter addressed through appropriate modeling of the spatial correlation between locations. The main body of this dissertation is a three-part work. Parts 2 and 3 pertain to the "many variables" problem, proposing novel methods of dimension …

Pulling Back The Curtain: A Student Collaborative Case Study Of Equity Issues In Colorado’S School Finance System, Amy Jo Schwartz

Electronic Theses and Dissertations

After the Great Recession, a seven percent decrease in funding ended decades of academic growth and further widened the achievement gap between White and Black students (Jackson et al., 2020). Colorado’s school-finance system is particularly distorted and inequitable because of a series of tax-limiting policies which, combined, have led Colorado to become one of the lowest-funded per pupil states in the country (Resnick et al., 2015). The purpose of this study is to describe the policymaking context, as it relates to equity within Colorado’s school-finance system and explore policy alternatives to improve equity within the system. The study was designed …

Railspace: A Geocritical Study Of The Railroad Through American Literature And Culture, Michael A. Smith

Electronic Theses and Dissertations

This dissertation uses geocriticism to argue that the American railroad is best understood as a set of discursively constructed railspaces formed through a variety of viewpoints, a polysensorial awareness of space, and stratified social relationships and power struggles. This study takes up four railspaces, the constituent texts of which demonstrate how intertextual discourse shapes and is shaped by the railroad. The observation car, charted through California Zephyr advertisements and Muriel Rukeyser’s “Campaign,” is an apparatus that produces perpetual spectacle. Three novels—Sister Carrie by Theodore Dreiser, Double Indemnity by James M. Cain, and Strangers on a Train by Patricia Highsmith—and …

The results allow for an examination of the fundamental practices of agricultural units, their perceptions and their experiences. In addition, they point to several implications for both policy and practice that may serve to guide our efforts to combat …

Original Free Will Baptist Clergy Role Stress: A Definition And Its Emotional Consequences, Dustin R. Bannister

Electronic Theses and Dissertations

The role of a clergyperson is often understood as one that creates a connection between the human and the divine, faith and God. However, such a vast role is typically executed in specific ways, such as leading Bible studies, visiting the sick, leading worship, and the act of preaching. At times, such a role demands even more nuanced behaviors based upon the context, population, and time. As this study posited, the problem is that such a multiplicity of clergy expectations inevitably create role stress, as understood through the constructs of role ambiguity and role conflict. In particular, how one might …

Brewing History: How Local Option And Prohibition Altered The Texas Brewing Industry, Shelby Winthrop Dewitt

Electronic Theses and Dissertations

The prohibition movement began decades before the Civil War but did not gain considerable support in Texas until the late nineteenth century.

This thesis and subsequent digital exhibit provide a …

Plasmodium Impairs Antibacterial Innate Immunity To Systemic Infections In Part Through Hemozoin-Bound Bioactive Molecules., Christopher Lynn Harding

Electronic Theses and Dissertations

Despite efforts to decrease the global health burden of malaria, infections with Plasmodium species continue to cause over 200 million episodes of malaria each year which resulted in 405,000 deaths in 2018 [1]. One complication of malaria is increased susceptibility to invasive bacterial infections. Plasmodium infections impair host immunity to non-Typhoid Salmonella (NTS) through activities of heme oxygenase I (HO-I) )-induced release of immature granulocytes and myeloid cell-derived IL-10. Yet, it is not known if these mechanisms are specific to NTS. We show here, that Plasmodium yoelii 17XNL (Py) infected mice had impaired clearance of systemic Listeria monocytogenes (Lm) during …

Getting Up: An Ethnography Of Hip Hop Graffiti Writers, Their Art, And Perceptions Of Society's Reactions., Theodore Malone

Electronic Theses and Dissertations

This ethnographic analysis of the modern hip hop graffiti writing subculture connects the separate but complementary theoretical constructs of serious leisure (Stebbins 1982), dark leisure (Smith and Raymen 2016), recreational specialization theory (Bryan 1977), and edgework (Lyng 1990) and situates the writer “standpoint” (Smith 1987) in terms of interrelations of policy and written discourse. Past research found that writers were motivated by fame and status, to express artistic skills, and to control and destroy space (Brewer and Miller 1990). Others found that writers sought to express contestant notions of style and resist economic and political authority (Ferrell 1996; 2006), and …

A Gis-Based Method For Archival And Visualization Of Microstructural Data From Drill Core Samples., Elliott Holmes

Electronic Theses and Dissertations

Core samples obtained from scientific drilling could provide large volumes of direct microstructural and compositional data, but generating results via the traditional treatment of such data is often time-consuming and inefficient. Unifying microstructural data within a spatially referenced Geographic Information System (GIS) environment provides an opportunity to readily locate, visualize, correlate, and explore the available microstructural data. Using 26 core billet samples from the San Andreas Fault Observatory at Depth (SAFOD), this study developed procedures for: 1. A GIS-based approach for spatially referenced visualization and storage of microstructural data from drill core billet samples; and 2. Producing 3D models of …
