Corazones Urbanos: Literary Cartographies And Southwest Cities In The Mexican American Spatial Imaginary, Jorge A. Hernández Jr.

Spanish and Portuguese ETDs

Corazones Urbanos: Literary Cartographies and Southwest Cities in the Mexican American Spatial Imaginary examines how Mexican American writers from Tucson, San Antonio, and Albuquerque narrate, critique, and reimagine urban space across the U.S. Southwest in the twentieth century. Integrating literary studies, cultural geography, urban history, and critical regionalism, the project analyzes responses to racialized development, urban renewal, and gentrification that have displaced Mexican American communities from historic downtowns. Moving beyond borderlands and transnational models, it advances a critically regional approach attentive to local histories, municipal policies, and community pressures shaping urban life. Through close readings of creative and nonfiction texts …

Examining Associations Between Socioecological Factors And Addiction Cycle Domains In Separate Community And Treatment- Seeking Samples, Kara Link

Psychology ETDs

The Addictions Neuroclinical Assessment (ANA) is a multimodal clinical assessment framework designed to capture the heterogeneity of addictive disorders and inform personalized treatment. The ANA is grounded in three neurofunctional domains aligned with the Koob and LeMoal addiction cycle stages: incentive salience (IS; binge/intoxication), negative emotionality (NE; withdrawal/negative affect), and executive function (EF; preoccupation/anticipation). In addition to these primary domains, the ANA also proposes ancillary assessment domains thought to be related to these neurofunctional domains. However, the ANA developers do not provide a rationale for including these ancillary measures in the framework nor hypothesize about their relevance to the ANA …

A Characterization Of Fat Acceptance Across Identities In A College Sample, Brynn Liabraaten

Psychology ETDs

Weight stigma is a class of discrimination in which those who are of higher weight face biases and discrimination. This can lead to worse outcomes ranging from poor mental health to societal barriers. Fat acceptance is the idea that all people, regardless of weight, deserve respect and equal treatment. The study of fat acceptance is in its infancy in the field of psychology, and there is little research addressing what kinds of people may be more or less fat accepting. The present study utilized a college sample to create a characterization of which intersecting identities and characteristics may correlate with …

Predictors Of Opposite-Sex Antipathy, Mikayla R. Poe

Psychology ETDs

Evolutionary pressures have shaped men’s and women’s motivations to cooperate and compete with one another. Sexual conflict is generated in natural conditions but may be exacerbated by features of the modern world. The current study recruited participants from Prolific to respond to a Qualtrics survey (n = 812) to investigate the correlates of opposite-sex distrust/antipathy using the newly developed Opposite Sex Antipathy (OSA) scale, which is the first of its kind to allow cross-sex comparisons. Men and women’s antipathy for each other was predicted by perceptions that the opposite sex was of lower value to society, more harmful experiences …

Through A Pueblo Lens: Sovereignty, Ethics, And Research In Tribal Communities, Elaine Suazo-Miller

Public Administration ETDs

This thesis explores the intersection of tribal sovereignty, ethical research conduct, and data ownership through an auto-ethnographic examination of my experience seeking research approval with the Pueblo of Santa Clara Tribal Council. Using the Pueblo’s protocols and decision-making processes as a lens, the study highlights how sovereignty is practiced in daily governance and how it shapes relationships between Indigenous communities and academic institutions. Three themes frame the analysis: (1) tribal sovereignty and building trust, (2) ethical research conduct and navigating the research process, and (3) data ownership, sensitivity, and sharing results. Each theme connects personal experience to key literature in …

Al-Manfiyun Exiliados: Voices Of The Lebanese Diaspora In Mexican Literature, Mia Del Rosario

Spanish and Portuguese ETDs

This thesis explores two key works of Mexican literature published in the late 20^th century in terms of their cultural relevance in the Mexican literary sphere. The novels En el verano, la tierra by Carlos Martínez Assad and Las hojas muertas by Bárbara Jacobs center around the infrequently-explored identities of Lebanese immigrants to Mexico and their Mexican-born descendants through a sociocultural lens, discussing their identity negotiation in the context of 20^th-century Mexico, which was in the process of redefining its national identity after the Mexican Revolution. During this time, people of ethnicities that did not fall into …

Dental Hygienists' Views On Salivary Diagnostics, Julie Justice

Dental Hygiene ETDs

This study assessed dental hygienists’ views on salivary diagnostic testing in the United States, including awareness, utilization, perceived barriers, and whether years of experience, clinical setting, or education level influenced these views. A descriptive cross-sectional design was used to collect data via an 18-item email survey distributed through the American Dental Hygienists’ Association’s mailing list. Eligible participants were licensed dental hygienists currently practicing in the United States. The survey included demographic items and Likert-scale questions on knowledge, clinical use, perceived value, and limitations of salivary diagnostic testing. Survey responses were analyzed using descriptive statistics, frequency distributions and Spearman correlations. Despite …

Evaluation Of Intracavity Electromagnetic Field Probes And Sources: Implications For Shielding Effectiveness, Joseph Anthony Ferreri

Electrical and Computer Engineering ETDs

To measure the electric field in a reverberant cavity, a small, minimally invasive probe is required. Common solutions include electrically small surface mounted monopole antennas, B-dots, and D-dots. To obtain an accurate field measurement with a particular probe, it is necessary to characterize it to compensate for its ability to convert electric field into voltage which requires a gauge factor known as effective height. The characterization process is straight forward in open space on a ground plane but requires more insight when in situ in a reverberant cavity. This work adapts ground plane probe characterization methods for cavity measurements, facilitating …

Quantifying Co2 And Ch4 Fluxes In A Semi-Arid Floodplain: Assessing Spatial And Temporal Drivers, Miles E. Kelsey

Earth and Planetary Sciences ETDs

Rivers transport sediment and carbon across Earth’s surface, and their floodplains can store carbon over decades to millennia, making them important to terrestrial carbon management. While soil carbon can persist long term, it may be released as greenhouse gases through processes like methanogenesis and heterotrophic respiration. Environmental controls on these fluxes remain poorly constrained across floodplains in different climate and geomorphic setting, but especially in semi-arid systems where measurements are limited. To address this gap, we quantified CO₂ and CH₄ fluxes along the Middle Rio Grande (New Mexico, USA) using 227 chamber measurements collected May to November 2025 at three …

Tiktok And The Brain: Neuropsychological Correlates Of Short-Form Video Consumption, Caty Enders

Psychology ETDs

Short-form video platforms like TikTok have quickly become the fastest growing segment of social media, thanks to powerful algorithms serving up personalized content driven by large quantities of user data. This study investigates the neuropsychological correlates of digital media use, with a particular focus on TikTok and smartphone screen time among young adults. Combining correlational analyses and an experimental design (n = 49; n = 44 included in final sample), we examined the relationship between digital media use and cognitive and emotional functioning across multiple domains. Objective measures of digital media consumption (daily average screen time and time on TikTok) …

Identity, Sexuality, And Gender: Perspectives From Self-Identified Sexually Fluid People, Mattilyn Wiseman

Psychology ETDs

Research on sexual fluidity has relied on categorical, gender-based measurement frameworks that prioritize quantifying change over exploring the lived experience of sexually fluid people. This study employed Interpretive Phenomenological Analysis (IPA) to qualitatively and ideographically explore how self-identified sexually fluid people made sense of their own sexual identity, gender (more broadly), and attraction as it relates or does not relate to gender. Three participants completed structured interviews with open-ended questions. Participants unanimously made sense of identity as a self-constructed journey and tied to their social realities. Participants’ lived experiences of their own gender identities informed their sense-making of gender more …

Clarifying The Illusory Truth Effect: The Role Of Truth Status And Source Memory, Kamille Koger

Psychology ETDs

The present study investigated whether repetition increases perceived truth even for information explicitly known to be false and how repetition effects interact with source memory. Participants (N = 102) completed two sessions (exposure and test) one week apart. During exposure, they rated the truth of trivia statements presented three times each. Half were explicitly labeled as "true" or "false" (known condition) and half were unlabeled (ambiguous condition). In the test phase, participants judged the truth of all previously seen statements and an equal number of new statements, followed by source memory judgments. Results showed a classic illusory truth effect (ITE) …

The Concept 'Pollination' And Bee Pan-Trap Color And Uv Reflectance Determine The Taxonomic Compositions Of Bee Taxa Captures Across An Elevation Gradient And Seasons In The Jemez Mountains Of New Mexico, Esther A. Burton, Kelly B. Miller, Paul J. Watson, David C. Witherington, Steven Poe, David Lightfoot

Biology ETDs

This thesis examines the pollinator concept and tests how sampling methods shape bee communities. Chapter 1 provides a conceptual and philosophical analysis, arguing that pollination is a process and that pollinators are context-dependent functional roles rather than fixed taxonomic categories. It traces the concept’s development from natural history to ecological theory, introduces a dual-goal model separating plant reproduction from visitor foraging, and proposes a classification framework based on evidentiary certainty and pollination potential to resolve ambiguity in pollination research.

Chapter 2 applies these ideas empirically by evaluating how pan-trap color and ultraviolet (UV) reflectance influence bee assemblages across elevation and …

From Cranes To Clinics: Genomic Epidemiology At The Human-Animal Interface, Sarah Shrum

Biology ETDs

Emerging infectious diseases represent a significant, increasing threat to human life, economic stability, and global security. The One Health framework, which promotes human health and wellness through the understanding that animal, environmental, and human health are interwoven, is critical to understanding pathogen emergence and transmission. This is underscored by the fact that roughly 60% of all human pathogens and 75% of emerging infectious disease are zoonotic, meaning they are transmitted from animals to humans.

The work presented in this dissertation integrates genomic epidemiology, ecological analysis, and One Health Surveillance approaches to characterize cross-species circulation of opportunistic yeast pathogens (Candida …

Reassembling Riparian Ecosystems: Stream Restoration Effects On Vegetation, Arthropods, And Aquatic-Terrestrial Connectivity, Katelyn P. Driscoll

Biology ETDs

Riparian areas exist at the aquatic-terrestrial interface and provide disproportionate ecosystem services, yet multiple stressors have degraded these zones globally. Stream restoration seeks to reverse degradation, but rigorous evaluation of treatment effectiveness remains limited. I conducted a before-after-control-impact (BACI) study in the southern Rocky Mountains to evaluate two stream restoration treatments—beaver dam analogs (BDAs) and plug-and-ponds (P&Ps)—across three dimensions of riparian ecosystem response. Using Bayesian analysis, I quantified treatment effects on functional diversity and composition of riparian plant communities. Using generalized linear mixed models, I evaluated restoration effects on riparian arthropod abundance, richness and guild composition across lateral gradients and …

Sexual Violence By Government Security Forces: Leaders, Institutions, And Culture, Margaret Avera

Political Science ETDs

I assess how the interaction between leader preferences, regime type, and agent personal motives impacts patterns of sexual violence. I ask, “Why do some government security forces perpetrate sexual violence while others do not?” and “How does the interaction between leader motives and institutions impact victimization patterns?” I found that police corruption was correlated with sexual violence by government security forces, but military corruption was not. My findings indicate the importance of moving beyond a conflict scope and distinguishing between different types of state security actors. In addition, I use natural language processing methods to collect disaggregated allegation data to …

Continuous Polygenic Trait Evolution Under Brownian Motion With Gaussian Mixture Models, Mary S. Hopkins

Mathematics & Statistics ETDs

Gaussian mixed-models (GMMs) show promise as a tool for modeling polygenic trait evolution for multiple taxa with established phylogenetic comparative methods (PCMs). When phenotypic traits are influenced by more than one gene, neither a gene tree nor a species tree may be completely adequate to model specific cross-taxa dependencies. In such cases common solutions include using trees inferred from concatenated DNA sequences [35, 95] and consensus gene trees [35]. The GMM-based model, first proposed by Jiang in 2017 [55] allows traits to evolve on more than one tree with distinct topologies. This approach provides a framework for trait evolutionary modeling …

Bayesian Designs For Two-Arm Clinical Trials With Time-To-Event Endpoints: Incorporating Historical Data Through Power Priors, Sara Hajraf H. Almutiri

Mathematics & Statistics ETDs

Bayesian methods provide a flexible framework for time-to-event analysis by incorporating prior information. The power prior offers a systematic way to borrow information from historical data. This approach is especially valuable in clinical research, where historical data can enhance inference in early-phase trials with limited sample sizes. This dissertation develops Bayesian approaches for two-arm survival studies using both closed-form and simulation-based methods. The closed-form inference is derived under exponential and Weibull survival models. Under the proportional hazards framework, the posterior is derived through a normal approximation to the log hazard ratio, allowing inference on the treatment effect when the variance …

Symbolists Beyond The Magic: Appropriation In The Art Of Elihu Vedder And Gustave Moreau, Rebecca B. Shalliker

Art & Art History ETDs

This thesis examines the paintings of Elihu Vedder and Gustave Moreau as examples of how the late nineteenth-century Symbolist movement drew on Eastern regions as aesthetic sources for representing the spiritual. Considering the iconographic and conceptual overlap with the Spiritualist movement, it explores how these groups contributed to constructing an image of the “East” as inherently mystical. While existing scholarship analyzes the Symbolist movement’s engagement with psychoanalytical concepts such as the subconscious and dream state, the role of cultural appropriation in shaping the Symbolist aesthetic has been largely overlooked.

The depiction of Eastern iconography as fantastical will be explored through …

Rhythms Of Hippocampal Function And Memory After Moderate Prenatal Alcohol Exposure, Lilliana May Sanchez

Psychology ETDs

Fetal Alcohol Spectrum Disorders involve morphologic and neurobiological abnormalities in offspring subjected to prenatal alcohol exposure. Although not as well studied as high exposure, moderate prenatal alcohol exposure represents the most common and undetected form in humans. While learning and memory deficits have been well characterized at the behavioral level in humans with Fetal Alcohol Spectrum Disorders and in animal models of moderate prenatal alcohol exposure, few studies have determined the circuit or systems level mechanisms of the behavioral deficits. A complete understanding of the neural bases of memory deficits after moderate prenatal alcohol exposure is needed to ultimately identify …

Torá: A Description Of A Dormant Chapacuran Language From Legacy Materials, Akasha Synclair

Linguistics ETDs

Torá, an Amazonian language of the Chapacuran family, went dormant as the Torá people survived colonization. Yet, in the early 1920’s, over 600 Torá words, phrases, and sentences were documented. Despite interest by today’s Torá community in language revitalization, no comprehensive analysis of the data has been undertaken. This project used methods of linguistic reconstitution, cross linguistic comparison, and the creation of an open-access database to produce a phonological and morphosyntactic analysis of Torá. Phonological findings of particular interest include evidence for vowel harmony and variable oralization of nasals. In structure, Torá is very similar to related languages, displaying a …

The Seeds Of Empire: Endogenous Influences On The Politics Of Bakumatsu And Meiji Era Japan (1853-1912), Benedict M.D. Talley

History ETDs

In this thesis, I argue the roots of Japanese nationalism, exceptionalism, and imperialism long preceded renewed contact with the West following American Commodore Matthew Perry’s historic 1853 expedition. Rather, late Edo Period (1603-1868) and Meiji Era (1868-1912) intellectuals and political figures looked to and were inspired by endogenous forces, ideologies, and intellectual movements of the Edo Period. Through a synthesis of secondary scholarship and analysis of Bakufu and Meiji Era figures’ writing, I seek to uncover the endogenous influences and de-emphasize western influence on the development of late nineteenth and early twentieth century Japanese nationalism and imperialism.

La Raza In The U.S.-Mexico Borderlands: A Comparative Regional Study Of Mexican American Elite Identity-Making From Texan Independence To The Mexican Revolution, Davis Diego Massey

History ETDs

After the U.S. annexed much of Mexico following the Mexican-American War, Mexicans in  the incorporated regions began to think of themselves as a racial group within the U.S. rather  than a distinctive nationality. The 1848 Treaty of Guadalupe Hidalgo promised citizenship  rights to all Mexicans in the area. The Treaty promises rarely were put into practice, as they  were left up to the enforcement of territories and states. Even where enforced, the rights of  citizenship were restricted and defined on the basis of race. Local laws excluded  Afro-Mexicans and Mexican Natives from exercising the rights promised by the Treaty. This …

Technical Advancements In Single-Molecule Spectroscopy For High-Throughput Measurement Of Long-Time Dynamics, Quyen B. Le

Chemical and Biological Engineering ETDs

Single-molecule fluorescence spectroscopy is a powerful technique for resolving transient biomolecular dynamics and quantifying free energy landscapes, kinetics, and binding interactions. However, two fundamental limitations restrict its broader application: slow, labor-intensive data acquisition and the limited observation time imposed by fluorophore photobleaching. These limitations hinder its use in drug discovery and biomedical engineering applications that require both high-throughput and access to long-time dynamics. In this work, both challenges are addressed through technical advancements. First, a simple, generalizable approach is introduced to automate data acquisition, eliminating manual intervention during experiments. This increases the acquisition rate by more than an order of …

Nuclear Deterrence: Enhancing The Mission Through Smart Factory Predictive Solutions, Jarrod Matthew Ronquillo

Chemical and Biological Engineering ETDs

To meet the stewardship and modernization initiatives set by the Department of Energy new technologies must enter the manufacturing facilities within the nuclear deterrent complex. Predictive solutions begin with collecting data. An equipment health monitoring device was created to streamline data collection and organization for equipment and processes. A predictive and process performance dashboard was developed for a deionized water system. The dashboard used Western Electric statistical process rules and a machine learning regression algorithm to predict when the resistivity would fall out of specification. Lastly, a remaining useful life calculation was developed for all equipment related to nuclear deterrent …

The Effect Of Acute Hypoxia Exposure, With Exercise, On Bone Metabolic Biomarkers, Alyssa Bailly

Health, Exercise, and Sports Sciences ETDs

Hypoxic environments, resulting from decreased atmospheric partial pressure of oxygen, reduce oxygen availability in the blood and tissues, leading to a mismatch between supply and demand. This elicits several physiological adaptations and may influence bone metabolism. Although evidence suggests that hypoxia can modulate bone remodeling through hypoxia-inducible pathways, findings remain mixed, with most data derived from chronic hypoxic exposures in animal and cell culture models. Exercise, an essential stimulus for bone health, may exacerbate hypoxic stress; however, the skeletal response to acute hypoxic exposure combined with exercise remains unclear. We propose that intermittent exercise in hypoxia may increase negative markers …

Benefits Of Advisory & Culturally Responsive Advisory Framework (Craf) Within A Southwestern, Urban, Dual Language Middle School, Mariana Anguelova Castañon

Language, Literacy, and Sociocultural Studies ETDs

In this research report, I examine the benefits of a daily Advisory period at a southwestern, urban, dual-language middle school and explore the impact of the Culturally Responsive Advisory Framework (CRAF), a curriculum I developed as a researcher-practitioner. This work is situated within research on Advisory programs, urban schooling, and dual-language education, while addressing implementation challenges. Grounded in democratic learning theory, CRAF integrates social-emotional learning (SEL), social-cultural learning (SCL), and literacy. To evaluate its impact, I collected qualitative data through anonymous Google Surveys and semi-structured student interviews, supported by quantitative teacher and student surveys. Data were analyzed using open and …

Helium Effects In High Entropy Alloys For Fusion Reactor Plasma Facing Components, Shane Evans

Nuclear Engineering ETDs

The plasma facing materials (PFMs) within fusion reactors, such as the divertor, must be able to withstand high temperature (>1000 K) for extended durations of time, in addition to extreme flux from neutrons, helium (He) ash, and neutral species such as deuterium and tritium. These materials must withstand these conditions while maintaining their selected mechanical properties, minimal sputter yield, and low fuel retention. In recent years refractory high entropy alloys (RHEAs) have been investigated due to their improved mechanical and irradiation-resistant properties when compared to pure W, the current material for PFMs. In this work RHEAs have undergone fusion …
