Fluvial Geomorphic And Hydrologic Evolution And Climate Change Resilience In Young Volcanic Landscapes: Rhyolite Plateau And Lamar Valley, Yellowstone National Park, Benjamin Newell Burnett

Earth and Planetary Sciences ETDs

Quaternary volcanism associated with the last caldera cycle in Yellowstone National Park included emplacement of ash-flow tuffs, massive rhyolite flows ranging from 79 to 484 ka, and valley-filling basalts. This study examines (1) the evolution of spring hydrology with flow age on the Rhyolite Plateau, (2) initial development and evolution of stream networks on the rhyolite flows, and (3) the impact of the 630 ka caldera formation and volcanic flow emplacement on Lamar Valley incision rates.

Integrated stream networks formed within 79 kyr on the Rhyolite Plateau. Incision is focused on steep flow margins and knickpoints and is dependent on …

Photo-Characterization Of Selective Luminescent Protein Aggregate Sensors - Oligo-P-Phenylene Ethynylene (Opes), Florencia A. Monge

Biomedical Engineering ETDs

Neurodegenerative diseases such as Alzheimer’s disease, Parkinson’s disease,

and related tauopathies, are a global health care challenge due to the lack of early

treatment and diagnostic options. These diseases take an emotional and physical

toll on patients, caretakers, and a rather large economic toll on taxpayer-based

health care systems. The pathologies of these diseases are characterized by the

aggregation of misfolded proteins, amyloid-β (Aβ) and tau, into β-sheet rich

structures called amyloids. Research has found that the presence of protein

aggregates predates cognitive symptoms by years. Current diagnostic tools are

based on the detection of these amyloid aggregates, historically by …

Reflections On Learning, Communication, And Identity In A Hybrid Course On Language Development, Anni Leming

Language, Literacy, and Sociocultural Studies ETDs

This research explored the relationship between the face-to-face and online spaces in my university hybrid course on first and second language development in cultural contexts, as well as my students’ and my own communication, learning, and development of identity as teachers and students. This study was grounded in practitioner inquiry and ethnography of communication as a methodological tool to understand the role of language among teacher and students in the virtual co-construction of knowledge. The findings suggest that self-disclosures, legitimizing the self and others, and relatability played key roles in students navigating new course content, a hybrid space and discussions …

“Pre-Packaged Sovereignty”: The Fallacy Of Indian Self-Determination In The Bureau Of Indian Affairs (Bia) Tribal Social Services Programs, April Kateri Chavez

American Studies ETDs

This thesis examines the Bureau of Indian Affairs (BIA) tribal social services programs in New Mexico Native reservation communities. I rely on interviews with current/former BIA social workers and administrators to contextualize my analysis, while revealing the limits of existing social work scholarship and offering recommendations for future scholarship and community work. Using critical Indigenous studies and feminisms along with critical social work, I advance two primary arguments. The first is, despite the so-called self-determination era, the Bureau of Indian Affairs (BIA) functions as a settler colonial administration that diminishes tribal sovereignty and perpetuates racist and gendered violence. The capacity …

Suicide, Heroin Use And Protective Resiliency Factors Amongst Transgender Adolescents In New Mexico, Richard Gadomski

Biomedical Sciences ETDs

Transgender people experience significant mental health inequities. The goal of this study was to evaluate disparities related to suicide attempt in the past 12 months and ever heroin use in cisgender versus transgender adolescents, and identify specific resiliency factors associated with a decrease in the prevalence of suicide attempt and heroin use in transgender adolescents. This study is a cross-sectional, secondary analysis of the 2017 New Mexico Youth Risk and Resiliency Survey among high school students. The odds of suicide attempt were 5.5-fold greater, and the odds of lifetime heroin use were nearly 14-fold greater, for transgender compared to cisgender …

Virus-Like Particle-Based Vaccines Induce Antibody-Mediated Neutralization Of Staphylococcus Aureus Virulence, Jason Alexander Joyner

Biomedical Sciences ETDs

Staphylococcus aureus is a pathogenic bacterium that inflicts a large amount of human suffering using an arsenal of virulence factors to cause minor to life-threatening infections. Both the accessory gene regulator (agr) operon, a virulence regulatory pathway that controls expression of over 200 virulence factors, and alpha-hemolysin (Hla), a key pore-forming toxin, play a significant role in infection severity. Given the clinical trial failures of S. aureus vaccine candidates and the prevalence of antibiotic-resistant strains, novel and effective treatment options are urgently needed. Chapter 2 describes a novel virus-like particle (VLP) -based vaccine inducing agr-I-inhibiting antibodies …

Interaction Of Optomechanical Cavities With Acoustic Waves And Oscillators, Ke Huang

Optical Science and Engineering ETDs

Resonators and oscillators are key elements in a wide variety of natural and manmade systems. As such understanding and exploiting their dynamics both as isolated devices and members of coupled systems has been the subject of intensive investigation for more than a century. The advent of optomechanical resonators (OMRs) that support strong coupling between optical and mechanical modes resulting in self-sustained optomechanical oscillations, has created new opportunities for device development and implementation of coupled oscillatory systems. One aspect of this thesis is focused on exploring some of the unique features of OMRs and optomechanical oscillators (OMOs) that can be exploited …

On Love And Treason: Critical White Feminist Thought For Social Justice Praxis, Amanda Joyce Parker

Language, Literacy, and Sociocultural Studies ETDs

This dissertation is a theoretical piece that examines the positionality of white women in upholding white supremacy and a framework for critical white feminist thought that will move white women toward a self-reflexive and self-implicating praxis. A white matriarchy (Parker, 2018) is fully conceptualized as part of a powerful subsystem that operates under white supremacy. Concepts, such as a race-gender bribe and white women’s negative solidarity (Combahee River Collective, 1977), are exposed and discussed as part of the workings of white matriarchy. White emotionality (Matias, 2015), intergenerational whiteness, and antiracist parenting are also analyzed. I also suggest possibilities for resistance …

Fusion Of Elastin Like Polypeptides To Rna Binding Motifs For Programmable Binding Of Nucleic Acids, Dominic Medina

Biomedical Engineering ETDs

Intrinsically disordered proteins (IDPs) with RNA binding capability have recently been found to play important roles in several cellular processes, including the formation of phase separated membraneless organelles to regulate gene expression. An important class of membraneless organelles is stress granules, which enable cells to survive periods of environmental stress by regulating gene expression in the cytoplasm. Cells use a variety of ribonucleoprotein granules, primarily comprised of RNA and chaperone protein components, and can regulate cellular metabolism by sequestering and processing regulatory components, such as messenger RNAs, within these phases separated ‘organelles’. To recapitulate this cellular behavior, the genetically engineered …

Biogeochemical Processes Affecting Arsenic (As) Release And Bioavailability Near Abandoned Mine Wastes, Cherie L. Devore

Civil Engineering ETDs

The aim of this dissertation was to investigate the biogeochemical processes affecting the mobilization and bioavailability of arsenic (As) from mining-impacted sediments to surface water sources and plants. The Cheyenne River Watershed has been affected by mining legacy for several decades. The biogeochemical cycling of As on tribal land is not well understood, which justified the following research objectives: 1) Investigate the effect of competing anions on the release of As from sediments exposed to oxidizing conditions; 2) Evaluate chemical and microbiological processes affecting the release of soluble As, Fe, and Mn from contaminated sediments under laboratory controlled aerobic and …

Post-Wildfire Geomorphic Stream Response In Six New Mexican Watersheds, Aljaz Praznik

Civil Engineering ETDs

Wildfire causes severe physical changes to watersheds, which then leads to geomorphic changes in the burned watersheds. In New Mexico and the southwestern U.S., flooding is a common response after a wildfire, due to higher water runoff from the hillslopes and sediment erosion rates. These flood events change the erosion and deposition characteristics of a stream, which can result in the deposition of a large amount of sediment near the communities living downstream. The objective of this research was to analyze and compare post-fire geomorphic stream response caused by six different wildfires in New Mexico with the goal to create …

Spatial Analysis Of Bias Corrected Rainfall Data Sets Within Albuquerque, New Mexico Metropolitan Area, Cassy Scarlott- Mcclintock

Civil Engineering ETDs

The Next Generation Radar (NEXRAD) was implemented as one of the first network-wide operational radar- estimated precipitation products in the United States in 1988. The algorithms within this system bring drastic advancements to operational flood forecasting when compared to prior radars and even rain gage systems. The objectives were; (1) to determine how radar plays a role in estimating precipitation by comparing rainfall accuracy to other sources such as calibrated radar data and gage data within Albuquerque, New Mexico and (2) to determine if distance from the radar affects estimation of rainfall. The sets of data compared were from: (1) …

Exploratory Study Of Communication As A Psychosocial Factor Influencing Safer Sex Experiences Among Individuals Who Identify As Polyamorous, Cecilia Brooke Cholka

Communication ETDs

Even with over three decades of research on and promotion of safer sex, the rates of sexually transmitted infections continue to rise in the United States (CDC, 2017). Although communication about risk and protective factors is key to the promotion of safer sex behaviors, the meaning and impact of such communication is contingent upon culturally grounded understandings of safer sex among individuals of diverse sexual subcultures. This dissertation focuses on individuals who self-identified as polyamorous, a style of non-monogamy, and their understandings and experiences with safer sex. Drawing on the application of the AIDS Risk Reduction Model and narrative inquiry …

Trespassing And Transcending: Newcomer Crossing And Movement In Latina And Latin American Literature, Marina C. Todeschini

Spanish and Portuguese ETDs

In times when walls are raised and human diversity condemned, stories that present the free urban movement of marginalized characters become political. While the system excludes the brown/black newcomer bodies and restricted them to the margins, the texts analyzed here bring these bodies to the center, claiming their active role in the construction of the urban fabric. This way, Latin American and Latina authors are contesting the idea of citizenship and the right to the city of newcomer subjects by narrating the freedom of geographic and symbolic movement of often disenfranchised peoples. This dissertation analyzes the claims to urban rights …

A High Altitude Electromagnetic Pulse (HEMP) is a potential threat to the power grid. HEMP can couple on transmission lines causing large overvoltages, which could be harmful to the line and everything else connected to it. The effects of overvoltages on all sorts of devices in the power grid need to be understood. The work developed here is a joint effort between The University of New Mexico and Sandia National Laboratories; The devices that are within the scope of this effort are Trip Coils and Lightning Surge Arresters (LSA). Existing data on HEMP, existing standards, and a previous analysis, were …

Software Execution Under Extreme Electromagnetic Interference, Luis Ariel Valbuena Reyes

Electrical and Computer Engineering ETDs

Software routines that deviate from the original algorithm’s goal due to a perturba- tion agent is a phenomenon that has been observed for a long time now. From unin- tended executions on flight control computers during the dawn of space exploration, passing through hardware Trojans tampering in corporate security, to sensitive med- ical equipment compromised to the point of changing the amount of delivered drug, the time intervals, and the reported biomedical measured data, such intrusions are a major risk challenging society. In this dissertation, a computer under perturbation is modeled by a hybrid sys- tem that captures the digital …

Impact Of Political Action Committee On Government Contracts, Bibek Acharya

Economics ETDs

This research aims to determine whether politically active corporations are more likely to get government contracts or likely to get more massive deals than corporations that are not politically active. The research question is, to what extent is the increase in government contracts due to the presence of corporate PACs or the amount spent by corporate PACs? In sum, we expect that the existence of PACs and the higher the corporation contributions in support of candidates for federal offices, the higher their chances of getting a contract or a more massive contract. We find that corporations that have a PAC …

Contesting Historical Enchantment: Militarized Settler Colonialism And Refugee Resettlement In New Mexico, Christina Juhász-Wood

American Studies ETDs

This dissertation provides an interdisciplinary critical study of refugee resettlement to Albuquerque, New Mexico. I argue that refugee resettlement to the United States cannot be understood separately from the ongoing structure of settler colonialism. I analyze Albuquerque’s post-WWII militarized settlement as a settler colonial process of extraction and suburbanization that depended on Native labor and resources to fuel the growing nuclear weapons program. Albuquerque’s Kirtland Air Force Base played a role not only in displacing and thus producing refugees during the Vietnam War but also in marking Albuquerque as a distinctly militarized geography to which they were resettled. Thousands of …

Nubians Of Plutonia: Black Women In Modern Post-Apocalyptic And Dystopian Graphic Literature, Marthia D. Fuller

American Studies ETDs

This dissertation explores the deployment of race and gender in comic books and graphic novels, paying close attention to how Black womanhood and girlhood operates in the speculative future. This project suggests that the framing of black womanhood and girlhood in post-apocalyptic/dystopian spaces provide a counter to the normative notions of both while simultaneously using normative tropes of Black womanhood and girlhood to produce new ways of understanding Black femininity in the future. Nubians of Plutonia use Black feminist cultural criticisms, Black popular culture, and visual culture to ask: does graphic literature present new, more dynamic understandings of race and …

Maximum Likelihood Estimation Of Species Trees And Anomaly Zone Detection Using Ranked Gene Trees, Anastasiia Kim

Mathematics & Statistics ETDs

A phylogenetic tree represents the evolutionary relationships among a set of organisms. Gene trees can be used to reconstruct phylogenetic trees. The methods in this dissertation focus on the gene tree topologies with emphasis on ranked gene tree topologies. A ranked tree depicts the order in which nodes appear in the tree together with topological relationships among gene lineages. One challenge that arises during phylogenetic inference is the existence of the anomaly zones, the regions of branch-length space in the species tree that can produce gene trees that have topologies differing from the species tree topology but are more probable …

The Experience Of Being A Parent Of A Child Who Stutters And Subsequent Involvement In Support Groups: A Narrative Study, Katlyn A. Ferguson, Richard Arenas

Speech and Hearing Sciences ETDs

INTRODUCTION: Developmental stuttering generally begins after a period of typical fluency and is highly variable in its presentation and persistence. This variability along with the lack of a definitive cause and social stigma often negatively impact both children who stutter (CWS) and their caregivers. However, research on the specific effects of stuttering on the caregiver is quite sparse compared to research into the caregiver experience in other disorders. Additionally, although social support has been identified as a primary protective factor for other caregivers, little evidence exists to show how support groups benefit caregivers of CWS.

METHOD: Five parents participated in …

Assessing The Validity Of Sentiment Analysis Measures Through Polychoric Correlation, Kelli N. Kasper

Mathematics & Statistics ETDs

Sentiment analysis methods extract the attitude of a text via systematic algorithms. To evaluate the validity of common sentiment analysis methods, we use polychoric correlation to compare computer-mediated methods and human-rated analogues. Our main topics of interest are the internal consistency of the raters' scores, the level of consensus among raters, and how well raters' scores correlate with those given by sentiment analysis methods for randomly collected Twitter data.

Our analysis found that there is good validity for methods that measure negative and positive sentiments in short texts, both in terms of inter-rater consistency and when comparing raters to computer-mediated …

Neogene Drainage Reversal And Colorado Plateau Uplift In The Salt River Area, Jordan Curtis Anderson

Earth and Planetary Sciences ETDs

The modern Salt River flows southwest from the Colorado Plateau, through the Arizona Transition Zone and into to the Basin and Range. Rivers in this area flowed northeast during the Paleogene from the Laramide Mogollon Highlands into structural basins of the topographically lower southern Colorado Plateau area. One of these rivers carved the Salt River paleocanyon through a portion of the Mogollon Highlands known as the Apache Uplift to similar depths as the modern Grand Canyon. This study refines the timing of this drainage reversal in the Salt River area by constraining the ages of paleoriver sediments deposited during the …

Triple Oxygen Isotope Composition Of Carbonates, Jordan A.G. Wostbrock

Earth and Planetary Sciences ETDs

This dissertation presents a method of analyzing the triple oxygen isotope compositions of carbonates, presents an empirical calibration of the carbonate-water equilibrium fractionation line, presents a triple oxygen isotope equipped fluid-rock mixing model for carbonates to see-through diagenesis, and applies all these findings to ancient carbonate samples. Using modern carbonates and associate water, the following equations are calculated to describe equilibrium triple oxygen isotope fractionation of carbonates:

1000lnalpha¹⁸O_cc-wt=2.84x10⁶/T²-2.96 1),

Theta_cc-wt=-1.39/T+0.5305 2).

Using these fractionation equations provides an extremely useful tool to determine whether a carbonate sample is altered or preserves …

Bodies In Shame: Writing Trauma And Affective Unsettlement In Post-Genocide Rwanda Fiction, Cole A. Carvour

Foreign Languages & Literatures ETDs

This thesis analyzes Boubacar Boris Diop’s Murambi, le livre des ossements and Véronique Tadjo’s L’Ombre d’Imana: voyages jusqu’au bout du Rwanda. I argue that both authors write trauma by employing both a dominant realist style and the trauma aesthetic with attention to the embodied experiences of genocide victims and survivors in both styles. In doing so, each author contributes to impeding indifference surrounding the 1994 Rwandan genocide. Furthermore, I assert that one effect of writing trauma is that of affective unsettlement or affective travel, or the registering of psychic and physical shame and other related affective responses in the …
