Toxic cultures incur tangible and intangible costs, impacting revenues, employee retention, and productivity. The pandemic has underscored the urgency of cultural alignment, prompting leaders to rethink behavior patterns. Engaging leaders across hierarchies as "chief culture officers" promotes accountability, openness, alignment, and leverage, fostering a …

Disrupting Whiteness In Education Organizations: Community Testimonios Of Strategy, Resistance, And Perseverance In Educational Justice Organizing, Florence E. Castillo

Sociology ETDs

Through this project, I utilize multiple approaches to disrupt whiteness. I make a case for centering Indigenous and non-Western methods, such as testimonio in sociological studies, to disrupt the academic whiteness of knowledge creation and validation. Whiteness itself is amorphous and looks different depending on circumstances, location, who holds power, and context (Hughey 2016). Utilizing a theory of racialized organizations, I shed light on how whiteness is normalized in education institutions through race-neutral, everyday actions (Ray 2019). This further disrupts whiteness by rendering it visible. Finally, I highlight the different modes of resistance that educational activists use to disrupt whiteness. …

Application Of Quantum Mechanical Techniques To Optical Waveguide Structures, Stuart Ward

Physics & Astronomy ETDs

The focus of this dissertation is on the application of supersymmetric quantum mechanics to the problem of microbending in optical waveguides and on the analysis of soliton decay due solely to quantum mechanical effects.

The techniques of supersymmetric quantum mechanics are applied to the equation of motion describing light propagation in an optical waveguide which is undergoing microbending. Based on these supersymmetric techniques, given a particular refractive index profile, one may derive a new refractive index profile which results in less loss due to the microbending -- the particular example of the monomial index profile is analyzed in detail. An …

Near- And Far- Field Optical Response Of Ensembles Of Nanostructures, Lauren Zundel

Physics & Astronomy ETDs

The ability of metallic nanostructures to support collective oscillations of their conduction electrons, known as surface plasmons, makes them attractive candidates for a wide range of applications in areas as diverse as cancer therapy, biosensing, and solar energy harvesting. These applications are especially promising for periodic arrays of nanostructures, which can support collective modes known as lattice resonances, and for nanostructures with extreme aspect ratios that give rise to enhanced light-matter interaction. In this Thesis, we employ a coupled dipole model to theoretically explore the lattice resonances supported by complex arrays of nanoparticles containing multiple nanoparticles per unit cell. We …

Resistance Narratives: Storytelling Of Transnational Insurgencies In 1960-70s Us And Mexico, Tania Libertad Balderas

English Language and Literature ETDs

Resistance Narratives: Storytelling of Transnational Insurgencies in 1960-70s US and Mexico emphasizes how the narratives from the Mexican Insurgency, the American Indian Movement (AIM), and the leftist faction of the Chicana/o Movement in the 1960s and 1970s articulate intersecting notions of resistance, liberation, and transnational solidarity. The comparative analysis of the testimonial novel Las mujeres del alba (2019) by Chihuahuan novelist Carlos Montemayor, the autobiographies Lakota Woman (1991) and Ohitika Woman (1993) by Sičháŋǧu Lakȟóta writer and AIM militant Mary Brave Bird (formerly Crow Dog), and the memoirs and plays by the San Diego-based group Teatro de las Chicanas, collected …

Digitally Rural: Identifying How Technological Inequity Impacts Rural Students In First-Year Writing Courses, Jo Anna M. Nevada

English Language and Literature ETDs

To teach composition in this era means to engage students with technology; it is all but an unspoken requirement at the majority of universities. This dissertation theorizes, however, that the imbricated use of technology in first-year writing (FYW) classrooms places rural students at an inherent disadvantage, with issues of inadequate technological proficiency and inconsistent access causing a substantial learning disparity between this student population and their urban peers. Through mixed-methods data analysis of student survey responses and final FYW course portfolios, this study reveals that the expectation of technological access and presumption of digital literacy is detrimental to rural student …

Long In The Tooth: The Commodification Of Teeth, Land, And Character; Resistance To British Oral Culture In Nineteenth-Century Britain, Ireland, And The Americas 1770-1900, Emma B. Mincks

English Language and Literature ETDs

This dissertation is about teeth- rather, how they are portrayed in British colonial discourses of the late eighteenth and early nineteenth century and their development as a commodified material object associated with purity, lands, and visceral emotionality. What do teeth specifically, and orality more generally, mean to eighteenth and nineteenth-century readers in relation to the logics of white possession? How did objectified subjects react to and respond to the affective tension created by this objectification? Teeth are represented in relation to feminine purity throughout British writing from at least the 1600’s. However, between 1770-1900, teeth gain additional cultural meanings, most …

Testing The Niche Center Hypothesis In The Fossil Record Of Atlantic Bivalves, Rhiannon Z. Nolan

Earth and Planetary Sciences ETDs

Paleoecological analyses of six shallow marine bivalves were conducted to test the Abundant Center Hypothesis using data from the fossil record of the Pleistocene through modern day. This hypothesis predicts the highest abundance of a species is at the center of the geographic or environmental range, decreasing toward the edges. In geographic space, distances to a centerline within a geographic range were variably correlated with population abundances, and some species displayed a sharp drop-off in abundance as distance increased. In environmental space, bivalve species showed moderate correlations between abundance and centrality when measured using cumulative data across the last 2.8 …

Seismic Analysis Of The Upper & Lower Falls Of The Yellowstone River, Loring Schaible

Earth and Planetary Sciences ETDs

Twelve years of concurrent hydrologic and continuous seismic data along with temporary seismic data demonstrate that the Upper and Lower Falls of the Grand Canyon of the Yellowstone River comprise a highly localized source of 0.5-5 Hz seismic energy that overwhelms anthropogenic contributions. In aggregate, seismic amplitude from 2008-2019 is linearly related to discharge with a correlation coefficient of 0.96. Repeated deviations from this linear relationship persist for 1-2 weeks prior to the date that Yellowstone Lake becomes clear of winter ice coverage. Seismic efficiency increases by ~50-250% during this period of ice-breakup, during which lake ice flows into the …

Seismic Shadow Zone Investigation In The Upper Magma Reservoir Of The Yellowstone Caldera, Sarah Nolt-Caraway

Earth and Planetary Sciences ETDs

This study investigates whether the Yellowstone Caldera has enough melt to mute S-waves, creating a seismic shadow zone. Using a dense nodal deployment of ~650 stations, 7-9 earthquakes during the nodal deployment, and 21 broadband stations with 3,000-4,000 events per station; amplitude and noise maps, seismograms, and automatic phase picks probabilities from a deep learning model were analyzed to assess the potential role of melt, crustal attenuation, and noise in affecting body waves, particularly S-phases. The results are inconclusive, with unclear evidence whether observed amplitude decay is normal signal decay due to distance, noise-related, melt, or from scattering and intrinsic …

Projecting Vegetation Condition And Fire Risk In Southern California, Westin K. Guthrie

Geography ETDs

In the western US, relationships between fire, vegetation, climate, and urban areas are dynamic and evolving. This work used a forest landscape model, LANDIS-II, informed by future climate scenarios and projections of urban expansion to understand wildfire interactions within projected Wildland Urban Interface (WUI) areas. This simulation showed that in both 2050 and 2100 +93% of the WUI in southern California experienced fire. Future work needs to be done in parametrizing forest biomass to ensure the validity of projections. Additionally, increasing each climate scenario model's replicates will create more accurate projections.

The findings affirmed a shift to using more diverse and appropriate language to represent people with disabilities more fairly and accurately; the categorization of most of the disability stories under “General News,” which suggests the significance attached to disability related stories; and the …

Queer Crises: Movements From Queerness And Feelings Of White Religion In The United States, Austin Williams Miller

Communication ETDs

Anchored by contemporary crises surrounding queer and trans people in the United States, I employ movements from queerness within an affective queer phenomenological framework to understand how arrangements of “white religion” (Schaefer, 2015, p. 63), a process whereby U.S. American Christian forms escape ideology into religious affective economies in the United States, relegate queer people “to the background… to sustain a certain direction” (Ahmed, 2006, p. 31). I assemble a queer rhetorical context analyzing white religious space in documentary film, secular sexual regulation through contemporary U.S. legal contexts around marriage, and settler colonial Christian nationalist political imaginations to critique how …
