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.

Witchy Politics: Witches And Witchcraft As Political Tropes From Malleus Malleficarum (1487) To Les Sorcières De La République (2016) And The Mercies (2020), Mallaury Joëlle Marie Gauthier

Foreign Languages & Literatures ETDs

The focus of this thesis are two recent novels featuring witches: Chloé Delaume’s Les Sorcières de la République(The Witches of the Republic, 2016) and Kiran Millwood Hargrave’s The Mercies (2020). The first is a futuristic dystopia set in 2062, during the witch trial of the Sibyl of Cumae. The second is a work of historical fiction based on witch trial records and set in seventeenth-century Finnmark (Norway). Both are feminist novels, and both emphasize the political valence of the witch as a gendered figure. This figure emerged from the misogyny of early modern demonology but acquired its contemporary contours …

Hydrothermal Liquefaction Of Wastewater Sludges For Energy Resource Recovery, Carl L. Abadam

Civil Engineering ETDs

This study aims to identify how variabilities in wastewater process configurations impact the biocrude yields from sludges processed and stabilized by hydrothermal liquefaction. Clean and renewable energy sources are vital to ensure a sustainable future. However, the current consumption of fossil fuels limits the ability to achieve this goal. Hydrothermal liquefaction (HTL) is a thermochemical process that converts wet biomass to valuable biocrude oil and biochar while reducing solid masses. Wastewater sludges were sampled across three facilities with varying influent design capacities and biological treatment configurations. Lipids extracted via solvent extraction and biocrudes produced from HTL were determined gravimetrically. Relative …

Role Of Endophytic Fungi On Arsenic Uptake In Solution: Insights For Bioremediation, Taylor Lillian Busch

Civil Engineering ETDs

Hazardous metals mobilized from natural deposits and mining legacy are environmental and human health concerns. The waters of our partner Native American communities affected by uranium and gold mining legacy exceed the EPA MCL of 10 µg/L arsenic (As). Bioremediation is a novel technology that uses native resources to remediate metals in the soil and groundwater. Plant-fungi symbiosis for bioremediation is widely studied, but the role of endophytic fungi in metal uptake is not well understood. The objectives of this study are to 1) determine As uptake by symbiotic endophyte Cadophora sp. and little bluestem grass (Schizachyrium scoparium) …

Identifying The Required Ecological Flow For Sediment Movement In The Río Chama: Field Data Informed Visual Spatial Model, Cristian Kremer

Civil Engineering ETDs

The continuous alteration of flow regimes in rivers has led to negative impacts on habitats and biotic communities, causing irreversible effects on river biodiversity. Implementing e-flows in management strategies can repair historical mismanagement, prevent further degradation, and restore ecosystem services. In the case of the Rio Chama, damming has altered its hydrological regime, affecting sediment transport. Experts recommend specific e-flow conditions for the Rio Chama to improve ecological conditions, in particular a bankfull discharge of 70 m³s^-1 every 2 years for sediment flushing and channel maintenance. The Río Gallina, a tributary of the Rio Chama, plays a …

Combining Semi-Continuous And Discrete Water Quality Data To Characterize Solute Transport, Biogeochemical Processes, And Wildfire Disturbances In Fluvial Systems, Justin Rae Nichols

Civil Engineering ETDs

In the past decade, high-frequency water quality sondes have become more abundant in watersheds across North America and Europe and are gaining a foothold in Asia and South America. In this dissertation, three relevant topics associated with high-frequency data are investigated, i.e., the impact of winter’s precipitation on surface water quality and stream metabolism, the longitudinal propagation of wildfire disturbances through a fluvial network, and the use of machine learning with high-frequency data to estimate fluvial nutrient processing. First, we found that significant snow precipitation can cause surface water anoxia and declines in stream metabolism. Second, our data illustrate that …

Civil Engineering ETDs

The Los Lagos region of Chile is experiencing ecological and socioeconomic challenges because of climate change. Despite efforts by the agricultural sector to understand and manage water resources, the lack of basic water quantification data affects their ability to effectively plan and implement water management strategies. This research aims to address this critical issue through three key objectives. First, characterize soil properties related to texture and structure in a micro-basin of the Los Lagos region. Secondly, it aims to investigate the hydrologic budget of the micro-basin with an emphasis on soil moisture using the Soil Moisture Routing model (SMR). Lastly, …

News Media Framing Of Disabilities In Ghana: Journalistic Practices Amidst Advocacy Calls For Change, Pamela Ofori Boateng

Communication ETDs

The study contributes to expanding scholarly research on media portrayals of people with disabilities in Ghana. Drawing on theories of framing, ableism, and intersectionality, I analyzed news stories published in Graphic.com.gh. in 2021 and 2022 to explore how the editorial practices framed people with disabilities and how framing patterns revealed change and continuity in representation. 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 …

“That Felt Weird”: International Graduate Students’ Emerging Critical Awareness Of Their Experiences With Microaggression, Romaisha Rahman

Language, Literacy, and Sociocultural Studies ETDs

The purpose of this phenomenological study was to uncover and understand international graduate students’ experiences with microaggressions that stem from native speaker fallacy; microaggressions are the subtle discriminatory behaviors executed toward marginalized groups and native speaker fallacy is the false belief that only some “native” English speakers are effective teachers and users of the language. Put simply, this research aimed at unveiling the subtle language-based discriminations that international graduate students experience in their day-to-day lives in U.S. educational settings. To collect data for the study, the Critical Incident Technique (CIT) was utilized. CIT is a method that allows the …

Slavery And Architecture Across The Mediterranean, John Behnken

History ETDs

Enslaved people as architectural material, found in the cultural examples of the Great Mosque of Cordoba and the Hagia Sophia, provide a lens from which scholars can re-envision the historical narrative. The scholarship surrounding the development and transition of the Great Mosque of Cordoba from a mosque to a church, elicits new research into what medieval people thought about race, race-making, and cultural ownership. The conceptions of race are evident through the medieval paradigms of enslavement. Who could and could not become enslaved establish social, cultural, and phenotypic classifications which in turn become race. The work of scholars such as …

Ayllus And Haciendas: Social Reproduction Of Community And Reciprocity In Nineteenth Century Ecuador, Laura Powell

History ETDs

This dissertation argues that indigenous peons of nineteenth-century Ecuador maintained ayllu practices of community and reciprocity through the reconfiguration of kinships networks and the reinterpretation of reciprocity within the context of the hacienda system. This argument challenges prevalent beliefs that indigenous networks of kinship and reciprocity largely dissolved with the rise of the hacienda system and the oppressive exploitation of the institution of debt peonage known as concertaje. However, a close reading of the hacienda records shows that, first, indigenous peons used their ability to accrue debt in order to build and maintain communities of both real and fictive kinship …

“The Wild Ones: Violence, Vengeance, And Sensationalism In The Borderlands”, Leah Candolin Cook

History ETDs

“The Wild Ones: Violence, Vengeance, and Sensationalism in the Borderlands” provides a microhistory of an incident that took place in the Arizona-Sonora border region in the late 1920s and early 1930s. The event involved the kidnapping of a Mexican boy by an Apache band living in the Sierra Madre Occidental, the American volunteer expedition to recover him, and the media frenzy that ensued. Untangling the multifaceted motivations behind the “Fimbres affair,” as the situation came to be known, and situating them within a longer history of sensationalizing and exploiting cross-cultural violence in the borderlands is one purpose of this study. …

The Haunting Aesthetics Of Empire: Filipinx America, Us Empire, And Cultural Production, Alana J. Bock

American Studies ETDs

Throughout this dissertation, I argue that US imperial knowledge production affirms US exceptionalism by disavowing the imperial violence wrought on the Philippines and its people. This disavowal not only renders the Philippines and Filipinx bodies illegible, but also haunts the Filipinx American diaspora. I argue that the haunted logics of empire are a set of relations, rather than specters of specific times and places, in which knowledge and power work together to continually produce and reproduce a specific and limiting reality and sensorium through which to view the world. In my interrogation of empire’s haunted logics, I not only look …

A Comparison Of Fixed Versus Moving Eulerian Meshes For 1-D Radiative Shock Problems, Dylan Weatherred

Nuclear Engineering ETDs

Testing codes used to solve the radiation-hydrodynamics equations requires the use of radiative shock problems. These problems contain stiff shocks and test the coupling of the material motion and the energy exchange between the radiation and material. However, these problems are difficult to solve due to large differences in time scale between radiation and material equations, resolving shocks, and modeling radiation and material interactions. This thesis will look to solve radiative shock problems in 1-D using the Eulerian formulation on fixed and moving meshes. The moving mesh method proposed takes advantage of the more simple Eulerian formulation of the radiation …

Miniature, Submersible Electromagnetic Pumps Of Molten Lead And Sodium For Gen-Iv Nuclear Reactors Development, Ragai M. Altamimi

Nuclear Engineering ETDs

Heavy metals and alkali Liquid Metals are suitable coolants for Generation IV terrestrial nuclear reactors for operating at elevated temperatures for achieving plant thermal efficiency more than 40% and the thermochemical generation of hydrogen fuel. In addition, the low vapor pressure of these liquids eliminates the need for a pressure vessel and instead operates slightly below ambient pressure. A primary issue with the uses of these coolants is their compatibility with nuclear fuel, cladding and core structure materials at elevated temperatures more than 500oC. Therefore, in pile and out-of-pile test loops have been constructed or being considered for quantifying the …

Probabilistic Modeling Of Social Media Networks, Distinguishing Phylogenetic Networks From Trees, And Fairness In Service Queues, Md Rashidul Hasan

Mathematics & Statistics ETDs

In this dissertation, three primary issues are explored. The first subject exposes who-saw-from-whom pathways in post-specific dissemination networks in social media platforms. We describe a network-based approach for temporal, textual, and post-diffusion network inference. The conditional point process method discovers the most probable diffusion network. The tool is capable of meaningful analysis of hundreds of post shares. Inferred diffusion networks demonstrate disparities in information distribution between user groups (confirmed versus unverified, conservative versus liberal) and local communities (political, entrepreneurial, etc.). A promising approach for quantifying post-impact, we observe discrepancies in inferred networks that indicate the disproportionate amount of automated bots. …

Tracing The Roots Of A Poisonous Tree: On The Origins And Impact Of Criminal Terminology In A Civil Apprehension Scheme, Shani Mahiri King, Nicole Silvestri Hall

New Mexico Law Review

Language is powerful. It can affect how we think about and treat groups of people. Poor language choices have a massive impact on immigration law, an area of the law that determines how groups of perceived “outsiders” are classified and regulated. Language and bias in judicial opinions have been studied, but less research has been done on poor language choices in immigration statutes. This Comment focuses on the harmful effects of poor language choices in immigration statutes, including the criminal terminology “arrest” and “warrant” in civil immigration apprehension statutes 8 U.S.C. Sections 1226 and 1357. Two fundamental problems arise when …

Big Data Policing Capacity Measurement, Ronald J. Coleman

New Mexico Law Review

Big data, algorithms, and computing technologies are revolutionizing policing. Cell phone data. Transportation data. Purchasing data. Social media and internet data. Facial recognition and biometric data. Use of these and other forms of data to investigate, and even predict, criminal activity is law enforcement’s presumptive future. Indeed, law enforcement in several major cities have already begun to develop a big data policing mindset, and new forms of data have played a central role in high-profile matters featured in the Serial and To Live and Die in LA podcasts, as well as in the Supreme Court’s leading privacy and criminal procedure …

Banding Together: Law Versus People Power In The United States, Benjamin E. Douglas

New Mexico Law Review

To become a democratic society, the United States must respect the people’s right to associate. This does not sound like a radical principle—freedom of association is part of the First Amendment—but realizing this freedom requires serious changes in existing policy. State and federal laws obstruct the ability of people to band together to shape the type of society that they wish to live in. People face severe restrictions impeding their right to form and direct value-based, powerbuilding, membership-driven organizations. I begin with an examination of the democracy deficit in this country, explored in three dimensions. First, when there are conflicts …

The Mindful First Amendment, Gary Myers

New Mexico Law Review

The mindfulness movement has begun to play an expanding role in personal well-being and in society more generally. Although there is an active push for mindfulness in law, its primary focus is on ways in which mindfulness techniques can help lawyers in their personal and professional lives. This article explores the possible contributions of mindfulness to the widely recognized challenges facing freedom of speech and freedom of the press in an era of severe cultural and political polarization. This article focuses on the external aspects of mindfulness—the interaction with others and with society—to assess whether its techniques might assist in …

Action Is Not Activism: Moving Martinez/Yazzie V. State Forward, Griffin Arellano

New Mexico Law Review

Education has long been regarded as the foundation of a strong society and fundamental to an individual’s ability to determine the course of their own life. Article XII of the New Mexico Constitution asserts that all students in New Mexico have a right to not just an education but one that is “sufficient.” However, in 2018, a state district court found that at-risk students across New Mexico were being denied that right. In Martinez/Yazzie v. State of New Mexico, the court ordered the State to quickly provide more funding for education and accountability mechanisms to ensure that money was spent …

Reaping The Rewards Of Hard Work: Eliminating The New Mexico Minimum Wage Act’S Exemption For Workers Paid On A Piecework, Flat Rate, And Commission Basis, Jackie Munro-Vahey

New Mexico Law Review

The federal Fair Labor Standards Act (“FLSA”) of 1938 created minimum wage, maximum hours, and overtime protections for the first time in United States history. One of the core principles of the FLSA was that states could also pass their own wage and hour laws, provided they were more protective of workers than the federal Act. In 2023, however, New Mexico is the only state where workers paid on a piecework, flat rate, and commission basis are exempt from the basic wage and hour protections of the federal Act because of a less protective state law. So, for example, medical …
