Second, it aims to contribute to typological research in emotion studies beyond established areas such as color, time, and space using innovative approaches. Specifically, this study focuses on fear and surprise to categorize their source domains using lexical and corpus-based methods. Examples were collected from constructions and the corpus, and patterns of FEAR and SURPRISE metaphors in Mandarin were compared with …

Citizen Science Helps Monitor Urban Biodiversity: An Interactive, Data-Driven, And Open-Source Perspective, Katie Slack

Geography ETDs

Story maps, a powerful tool for communicating environmental narratives, are often commercial and lack many interactive functions. We integrate a data-driven and interactive geovisualization within an open-source story map created from high-attribute citizen science datasets. This story map creates a backend programming infrastructure for accessible, open-source science communication tools. Our story map intuitively communicates the findings from our web map application (app) portion of the story map to the public and helps reveal findings from the iNaturalist datasets. Albuquerque, New Mexico, United States is a demonstrative case study, but our tools can be flexibly adapted to other cities. Geovisualizations revealed …

Toward Simulating 2d Cell Surfaces In A Disk, Myriam Allred

Mathematics & Statistics ETDs

Certain evolution models of cell surfaces (treated in two-dimensions) involve the solution of the Helmholtz equation with jump conditions enforced on an immersed closed curve. This thesis presents a sparse, modal spectral method for solving such Helmholtz problems. The solution is required to be continuous across the curve, but with a jump discontinuity in the normal derivative proportional to the planar curvature. The method relies on classical Fourier-Chebyshev basis functions, with the application of modal Chebyshev integration matrices to achieve sparse, banded approximations of the Helmholtz equation. The method achieves spectral convergence, despite the inherent low regularity of the relevant …

Assessing The Ecological Drivers And Consequences Of Partial Migration In Hudson River Striped Bass Over Three Decades, Caitlin Egan Zimmer

Biology ETDs

Climate change and shifts in human land use have caused extensive impacts to the connectivity, structure, and resilience of aquatic populations. Partial migration (PM), where only some individuals from a population migrate while the rest remain resident, can mitigate population-level responses to environmental stressors. However, little is known of the underlying mechanisms promoting variation in migration and whether these shift over time. In the Hudson River Estuary, striped bass (Morone saxatilis) are known to exhibit anadromous PM behavior. Here, I measured carbon isotopes (δ¹³C) of essential amino acids in striped bass scales to determine variation in …

Plant Reproductive Strategies Shift In Response To Restoration Using Beaver Dam Analogs, Laurel F. Martinez

Biology ETDs

As riparian communities become increasingly degraded, restoration treatments are being implemented in streams to recover ecosystem functions. In the Jemez Mountains, beaver dam analogs (BDAs) are used to restore degraded streams by connecting the floodplain and increasing the extent of anoxic soil conditions. These environmental disturbances are expected to alter how riparian plants recruit, particularly their allocation to seed-based and vegetative regeneration strategies. We investigated whether BDAs and associated changes in soil water filled pore space (WFPS) affected riparian plant recruitment. We investigated the number of flowering stems as a proxy for seed-based regeneration and rhizome length and mass as …

Ecoimmunology Of Dirty Physella Acuta Snails, Kevin Arthur Mcquirk

Biology ETDs

Research on Physella acuta, an invasive freshwater snail, reveals insights into its parasitology, fitness, and molecular biology. Morphological and molecular analyses revealed two distinct mitogenomic lineages, local (B) and invasive (A) strains of native P. acuta, both having comparable trematode infection rates, suggesting that the low infection rates observed from A in invaded regions result from "enemy release" rather than immune incompatibility. Fitness assessments showed that while lineages A and B performed similarly under laboratory conditions, rewilding experiments revealed significantly higher fitness in lineage A. Transcriptomic profiling supported these differences, with A snails showing greater immune-related gene expression and …

Using Triple Oxygen Isotopes To Investigate Water Usage In Desert Ecosystems, Cloe V. Knutson

Earth and Planetary Sciences ETDs

In arid environments, maintaining water balance can be more critical for survival than obtaining food. As droughts intensify, understanding how animals manage body water is essential. Triple oxygen isotope analysis provides a novel way to trace water sources in animals, distinguishing contributions from free water, food-derived oxygen, and atmospheric O₂. We developed an equilibration method using CO₂–H₂O oxygen exchange and measured δ^’18O and Δ^’17O values via tunable infrared laser direct spectroscopy (TILDAS). Validated against traditional fluorination methods, this technique enables streamlined analysis of whole blood and plant samples. Applied to …

This study is significant in exploring the different ways in which Deaf Black youth construct their identities through the use of narrative inquiry. Educators of Deaf youth should acknowledge how the identity journeys of Deaf Black youth are often affected by the school and home communities. This research employed narrative inquiry to understand how Deaf Black youth construct their identities as Black Deaf individuals. Using Critical Race Theory (CRT) as a theoretical framework with the guidance of Intersectionality and Dis/ability Critical Race Theory (DisCrit) lenses, the study specifically examined four Deaf Black youth’s narratives to highlight how they construct and …

Microneedle-Based Lc-Ms/Ms Profiling Of Dermal Interstitial Fluid Reveals Early Lipid Dysregulation Contributing To Painful Neuropathy In Prediabetic And Type 2 Diabetic Rats, Srinivasa Rao Gadam

Biomedical Sciences ETDs

Painful diabetic neuropathy (PDN), a complication of type 1 and type 2 diabetes, also occurs in obesity and prediabetes, with dyslipidemia as a modifiable risk factor. The distal-to-proximal neuropathy pattern and length-dependent intraepidermal nerve fiber loss suggest peripheral contributions. We hypothesized that elevated neurotoxic lipid intermediates—diacylglycerols (DAG), free fatty acids (FFA), and acylcarnitines (CARs)—in the dermal interstitial fluid (ISF) drive metabolism-associated hyperalgesia in prediabetic and diabetic rats. Using a microneedle array (MIA) with LC-MS/MS, we profiled ISF and serum lipids from high-fat diet (HFD) and HFD + streptozotocin (STZ) rat models alongside Hargreaves testing. ISF lipid changes appeared earlier (weeks …

Immune Regulation In Fungal Airway Inflammation And Host Defense, Ruoning Wang

Biomedical Sciences ETDs

Asthma is a chronic inflammatory disease of the lungs characterized by complex pathophysiological mechanisms and diverse endotypes, primarily categorized as T helper type 2 cell (Th2)-high and Th2-low asthma. Despite significant advances in understanding asthma pathogenesis, the mechanisms governing the pulmonary immune system’s response to external challenges have not been fully understood. To address these gaps, this comprehensive project was designed to investigate the interplay between fungal infections and specific CD4⁺ T cell populations in asthma. Our findings suggest that fungal infections can contribute to neutrophilic asthma by promoting the migration of platelet-myeloid aggregates into the lungs. We also …

Interdependence And Place In Mescalero Homelands, 1660-1865, Joseph A. Ukockis

History ETDs

This dissertation examines strategic relationships that Mescalero Apaches made among themselves and with non-Mescalero communities from 1660 to 1865. It references Mescalero place names in piecing together pertinent stories across their vast ancestral homelands, demonstrating regional continuities in social, political, and economic dynamics over two centuries. It argues that bonds of interdependence, rather than armed resistance, were critical in maintaining autonomy and the ability to move freely, conduct effective diplomacy to protect claims to homelands, access resources in times of scarcity, and form key alliances that presented possibilities for resistance to colonial domination. Central to these dynamics were Mescalero and …

Exploring Immune System Through Computational Modeling: A Comprehensive Study Of Lymph Nodes And Immune Response Scaling, Vaccine Efficacy, And Large-Scale Extreme First Passage Time, Jannatul Ferdous

Computer Science ETDs

The adaptive immune response is a complex defense mechanism that develops over time to recognize and eliminate pathogens with remarkable precision and durability. This dissertation investigates the dynamics, scaling, and efficiency of the adaptive immune response through a synthesis of computational modeling, mathematical analysis, and agent-based simulations. First, we analyze the topology of the lymphatic network and investigate the T cell search time to find the lymph node that is containing the matching dendritic cell. Second we show how the scaling of lymph node number and volume with body mass, leads to scale-invariant search times for T cells locating antigen-bearing …

The Nature Of Anthropogenically Driven River Drying: Spatiotemporal Causes And Consequences, Eliza Inez Gilbert

Biology ETDs

Streambed drying naturally occurs in over 60% of rivers and streams worldwide. Climate change and human regulation of surface and groundwater have increased drying in naturally intermittent systems and caused perennial systems to transition to intermittency, impacting water security, water quality, and biodiversity. To understand human-induced drying dynamics, we used 12 years of daily drying data along a 154-km regulated reach of the Rio Grande. We conceptualized river drying as a regime analogous to the natural flow regime paradigm and quantified drying magnitude, rate of change, and duration. Although linear models predicting drying magnitude and rate of change were uninterpretable, …

Educating Healthcare Providers To Prevent And Mitigate The Effects Of Zoom Fatigue, Andrea Lima

Doctor of Nursing Practice Scholarly Projects

Zoom Fatigue (ZF), or physical and neuropsychological responses to excessive videoconferencing (VC), increased during the COVID-19 pandemic. Like burnout, ZF can compromise patient safety by causing decreased job satisfaction, social isolation, disrupted focus, and difficulty empathizing with patients. This Plan-Do-Study-Act quality improvement project aimed to assess feelings about VC, raise awareness of the adverse effects of overuse, and empower primary care providers (PCPs) to improve their work experiences. A group of on-site PCPs at a tertiary care medical center in the Southwest, who continued holding exclusive virtual team meetings after the pandemic, was asked to complete the 15-question Zoom Exhaustion …

Genetic Gain And Loss In The Evolution Of Amniote T Cell Receptor And Immunoglobulin Genes, Jordan M. Sampson

Biology ETDs

The immune system of most jawed vertebrates consists of three major cell types: αβ T cells, γδ T cells, and B cells. Every species evaluated contains the loci that encode the highly conserved αβ T cells, however, γδ T cells are less conserved and have been lost in squamate reptiles. The loci that encode the B cell receptor have also varied across evolution. Seven immunoglobulin (Ig) heavy chain isotypes have been identified in amniotes: IgM, IgD, IgY, IgG, IgE, IgO, and IgA. Some are found in most species (IgM and IgD) and others only in specific lineages (IgY or IgG). …

Uses And Abuses Of Johnson V. M’Intosh In Native American Land Rights Cases: Investigative Insights From The Indian Law Justice Files, John P. Lavelle

Faculty Scholarship

The 200th anniversary of the foundational Indian law decision Johnson v. M’Intosh has come and gone, with many scholars contributing criticism and commentary. The dominant focus has been the case’s notorious embrace of the so-called “doctrine of discovery,” an odious theory for rationalizing European nations’ claims of superior rights to lands occupied by Indigenous Native American peoples. Commanding less attention, however, is the Johnson decision’s core protective legal feature, i.e., its reinforcing the United States government’s duty to guard against the alienation of Indian lands through private, unauthorized acquisitions.

This Article offers a somewhat different appraisal of Johnson v. M’Intosh …
