You Can't Teach Kids From A Book: Language, Authority And Revitalization In Jicarilla Apache Life, Mariann Skahan

Anthropology ETDs

This dissertation examines how Jicarilla Apache is learned, taught, and used across community life, with particular attention to contemporary language revitalization. Based on ethnographic research with elders, educators, language workers, families, and community institutions, it follows language practices across classrooms, culture camps, homes, ceremonial settings, and collaborative archival projects. I show that linguistic knowledge does not carry the same authority or consequences in every setting. Words may be recognized without being taken up, speakers may possess linguistic knowledge without being authorized to teach or correct, and archival texts may preserve linguistic forms without preserving the relations needed to interpret and …

New Distance Distributions Of Asymptotic Giant Branch Stars And Their Role In Tracing Galactic Structure, Rajorshi Bhattacharya

Physics & Astronomy ETDs

Asymptotic giant branch (AGB) stars are among the final evolutionary stages of low- and intermediate-mass stars and among the most luminous cool stellar populations in the Milky Way (MW). Their strong infrared emission allows them to be observed through regions of high interstellar extinction, making them useful tracers of the inner MW. However, their use is limited by unreliable distances because many are dust-obscured and variable, while geometric parallaxes are often unavailable or uncertain. This thesis develops statistical distance-estimation methods for large samples of oxygen-rich AGB stars. The resulting distances broadly agree with literature estimates, supporting their statistical reliability for …

Extending The Discovery Space Of Tess: Probing Underexplored Exoplanet Populations, Mallory L. Harris

Physics & Astronomy ETDs

This dissertation investigates how cold exoplanets can be identified despite the strong observational bias of exoplanet surveys toward short-period systems. Planets at wider orbital separations remain comparatively poorly constrained, limiting tests of planetary-system formation and the prevalence of outer architectures beyond compact systems. To address this gap, I use two complementary approaches. First, I develop a transit-search pipeline for TESS Full-Frame Images that identifies both isolated and repeated transit-like signals around nearby M dwarfs and characterizes the dominant false-positive classes that limit sensitivity in this regime. I then present TOI-904 c, the coldest planet discovered by TESS around an M …

An Investigation Of Tess M&Ms And The Occurrence Rate Of Transiting Circumbinary Planets, Dominic Oddo

Physics & Astronomy ETDs

Circumbinary planets (CBPs) are worlds which orbit two stars simultaneously. CBPs are excellent tests of the tenacity of planet formation, but are difficult to detect. The space-based NASA Transiting Exoplanet Survey Satellite (TESS) mission is a nearly all-sky survey designed to detect exoplanets transiting nearby stars. In this dissertation, I analyze the performance of TESS by comparing to the photometric precision of the ESA CHEOPS mission. Then, I define a catalog of low-mass eclipsing binaries (M&Ms), which are the best sources to search for CBPs. I describe my custom transit search methodology and apply it to the M&M catalog. I …

Strategies For Large Dynamic Range, Entanglement-Enhanced Quantum Metrology With Experimentally Demonstrated Resources, Tyler G. Thurtell

Physics & Astronomy ETDs

Quantum metrology studies the use of quantum mechanical systems as measurement devices or sensors. Surprisingly, preparing a sensor in an entangled state can enhance measurement precision. The simplest protocols for entanglement enhancement sense only small changes in a quantity. The range of values over which a measurement protocol works is called its dynamic range. For many types of sensors we require end-to-end protocols that describe how to use entanglement to achieve enhanced precision over a large dynamic range. In this dissertation, we describe two approaches to achieving entanglement-enhanced sensing over a large dynamic range. The first approach uses entangling resources …

Quantum Control Of Qubits And Qudits In Neutral Atom Systems, Sri Datta Vikas Buchemmavari

Physics & Astronomy ETDs

This dissertation explores control of neutral atom quantum systems across multiple levels of abstraction, from atomic physics to system-level fault tolerance, using optimal control to improve performance. First, we propose a Rydberg entangling gate based on dressing with only the qubit control field; an interaction energy near the Rabi frequency benefits both gate speed and Rydberg decay. Second, with Sandia National Laboratories, we show that leakage errors in neutral atom systems can be converted to atom loss errors and detected using two entangling gates with an auxiliary atom, where a SWAP-based leakage detection unit outperforms the standard design. Next, we …

Naturalistic Aided Language Intervention For Children Who Have Multiple Disabilities Including Visual Impairment, Naomi Nattress

Speech and Hearing Sciences ETDs

ABSTRACT

This dissertation examined aided AAC interventions for individuals with multiple disabilities, including visual impairment, across three original studies. Chapter 2, a meta-analysis, found limited rigorous research for this population while showing that individuals at early symbolic stages with diverse visual profiles can successfully engage with AAC when appropriate adaptations are provided. The pilot study in Chapter 3 indicated that caregivers and graduate student clinicians can learn and implement naturalistic AAC techniques and VI accommodations with high fidelity through structured coaching. The mixed methods study in Chapter 4 introduced the ImPAACT-VI program, showing strong outcomes in educator performance, students’ symbolic …

Understanding The Long-Run Effect Of Historical Redlining Practices, Yujian Lu

Geography ETDs

Historical redlining practices initiated by Home Owners’ Loan Corporation (HOLC) in the 1930s have produced enduring persistent socioeconomic and environmental disparities in U.S. cities. This dissertation examines their long-term impacts on social vulnerability, urban flood risk, along with public discourse about redlining practices. Results indicate that neighborhoods with HOLC grade A (greenlined) exhibit the lowest overall social vulnerability, while those graded D (redlined) face the highest across U.S. cities. In Chicago, associations between redlining practices and flood risk disparities are stronger than in Los Angeles, reflecting place-specific characteristics among environmental, socioeconomic, and demographic factors shaping flood risk disparities in long …

How Forest Structure And Climate Influence Snowpack For Water Resources In The Southwestern United States, Lindsey L. Rotche

Geography ETDs

Climate change, declining snowpack, and increasing wildfire risk have profound impacts on water availability in the southwestern United States. Because the southwestern United States is a global hotspot for freshwater vulnerability, and snowpack provides much of the region’s freshwater, understanding how climate and forest structure influence snowpack dynamics is increasingly important. In this dissertation I aim to better understand and communicate these dynamics through empirical data collection and the development of a simple vegetation driven temperature-index snow model: SNOW-17(VEG). I then implement the model at a watershed scale using remotely sensed imagery to create vegetation zones and climate simulations to …

Helmholtz Reciprocity In Bidirectional Y-Junction Couplers, Hosuk Lee

Optical Science and Engineering ETDs

This thesis explores the light propagation characteristics in Y-junction couplers based on the Helmholtz reciprocity principle. The Helmholtz reciprocity principle is a crucial concept in optical system design, and it has primarily been understood based on input-output symmetry. However, this study emphasizes reciprocity needs to consider the entire system, beyond the traditional input-output symmetry reciprocity interpretation. For this study, we specifically examined the direction-dependent asymmetrical outputs, in the Whistle-geometry Ring Laser (WRL) structure. And the WRL results cannot be fully explained by simple input-output symmetry for reciprocity. The Y-junction coupler in the WRL structure makes different output characteristics based on …

Algorithmic Sculpting Of Complex Fused Silica Surfaces For Nondestructive, Mode-Matched Cavity Quantum Electrodynamics: Adaptive Co2 Milling And Simulation-Guided Ultrafast Inscription, From Fiber Fabry-Perot Cavities To Monolithic Architectures, Meagan E. Parker

Optical Science and Engineering ETDs

Quantum sensors achieve exceptional measurement sensitivity through coherent, well-isolated quantum systems, but practical deployment is hindered by destructive readouts that require repeated state preparation and create long system dead times. Optical cavities enable continuous, nondestructive measurements with minimal back-action, yet integrating high-finesse cavities into scalable quantum devices remains limited by existing fabrication methods. To overcome these constraints, an adaptive CO₂ laser-milling platform was developed. Guided by glass thermodynamics and melt dynamics, this closed-loop system uses in-situ phase-shifting interferometry to sculpt complex fused-silica surfaces with sub-nanometer root-mean-square roughness. The platform was validated by fabricating extended-length fiber Fabry–Pérot cavities and monolithic micro-cavity …

Keeping Communities Safe Through An Alternative First Response Model: Predictors Of Civilian First Responders’ Self-Efficacy In Handling Crisis Situations, Jasmine Desiderio

Organization, Information and Learning Sciences ETDs

The expansion of civilian alternative first responder models reflects a national shift toward community-based approaches to crisis intervention. Grounded in Albert Bandura’s social learning theory, this study examined the extent to which demographic characteristics are associated with crisis self-efficacy, explored how perceptions of the responder role relate to confidence, and identified supports necessary for effective crisis response. A convergent parallel mixed-methods design was employed with civilian first responders in Albuquerque, New Mexico. Quantitative data were collected with the Crisis Self-Efficacy Scale, and semi-structured interviews gathered qualitative data. Exploratory regression analyses (n=31) were not reliably associated with crisis self-efficacy, while role …

3d Electromagnetic Simulations Of A 1.6 Cell S-Band Photoinjector: Emittance Studies For Electron Microscopy, Trudy Bolin

Electrical and Computer Engineering ETDs

Modern beam-based materials research demands electron sources with increasingly precise time resolution, high brightness, and stability. For example, there are various instruments across the U.S. dedicated to ultrafast electron diffraction (UED), but fewer are dedicated to ultrafast electron microscopy (UEM), which demands beam stability. Modeling femtosecond electron bunches with ultra-low emittance < 50 nm-rad inside a 1.6-cell S-band (2856 MHz) rf photoinjector with full 3D electromagnetic simulations can require high-performance computing (HPC) environments due to the scale disparity between the macroscopic cavity geometry and the femtosecond-scale bunch kinematics. To enable optimization in a desktop computing environment, this work presents a streamlined 3D electromagnetic Particle-in-Cell (PIC) simulation framework optimized for 400-femtosecond bunch regimes. The covariance method was employed to study emittance properties for electron bunch counts ranging from thousands to millions and has successfully resolved highly transient, pure rf phase-space rotations, such as a localized energy-spread minimum occurring at the gun exit iris. To overcome the computational cost of these simulations, a machine-learning-based Bayesian optimization approach was deployed to construct multi-objective Pareto fronts from sparse datasets. Because the simulation software is scalable from desktop to HPC facilities, the framework is ready for experiments at the National Energy Research Scientific Computing Center (NERSC) at Lawrence Berkeley National Laboratory (LBNL).

Real-Time Waveform Synthesis For Rfsoc-Based Quantum Control Systems, Tiamike I. Dudley

Electrical and Computer Engineering ETDs

RFSoCs are gaining adoption in many labs for quantum control systems thanks to their compactness and affordability. Making full use of the many components on an RFSoC evaluation board is a challenging engineering problem that must be solved to realize scalable control systems. In this dissertation, I evaluate the performance of various RFSoC components in the context of quantum information science. I present two custom FPGA engines that accelerate and parallelize arbitrary waveform generation. The first engine can be instantiated many times to power low-speed DACs for ion-shuttling trap electrodes. The second engine synthesizes CPMG-XY8n dynamical decoupling pulse sequences on …

Multi-Robot Cooperative System For Complex Aerospace Manipulation Tasks: Theory And Application, Longsen Gao

Electrical and Computer Engineering ETDs

Multi-robot systems can extend manipulation capabilities beyond the limits of a single robot, particularly for tasks involving large, flexible, delicate, or free-floating payloads. Reliable cooperative manipulation, however, remains difficult when payload dynamics, contact geometry, compliance properties, deformation-induced forces, and external disturbances are only partially known, and when safety constraints must be enforced during physical interaction. This dissertation develops a two-layer control framework for resilient multi-robot manipulation under uncertainty, with emphasis on space servicing, satellite stabilization, aerial transportation, and cooperative manipulation of free-floating structures.

The Dental Hygienist Perspective On Laser Use For Nonsurgical Periodontal Therapy, Tammie A. Nyce Mrs.

Dental Hygiene ETDs

The purpose of this study was to assess the perceptions, attitudes, and experiences of dental hygienists regarding the use of lasers in the non-surgical treatment of periodontal disease.  A descriptive survey was distributed via email to current active and inactive members of the American Dental Hygienists’ Association. The sample consisted of practicing dental hygienists who had received training in laser use and lived in states that allowed laser use by dental hygienists.   Those dental hygienists who are not practicing clinically, who are not trained in the use of lasers, and who do not have experience using lasers in the treatment …

Developing A Dispersion Interferometer For Characterizing Power Flow Plasma Formation And Transport Studies, Nathan R. Hines

Electrical and Computer Engineering ETDs

Sandia's refurbished $Z$-pinch machine experiences persistent current loss in its post-hole convolute and inner magnetically insulated transmission line regions, widely attributed to low-density electrode plasmas whose formation and transport remain poorly constrained by existing diagnostics. This dissertation develops and validates a fiber-coupled, continuous-wave, second-harmonic orthogonally polarized dispersion interferometer for time-resolved measurements of electron areal density in millimeter-scale gaps. The diagnostic employs single-laser second-harmonic generation, non-steering differential phase control, and polarization-based phase retrieval to achieve sub-$10^{15}$~cm$^{-2}$ sensitivity, multi-hundred-megahertz bandwidth, and sub-$200$~$\mu$m effective cross-gap spatial resolution. Performance is benchmarked against a $94$~GHz interferometer on the UNM Helicon-Cathode plasma device and then fielded …

Systematic Errors In Judging The Performance Of Others, Michael J. Benson

Psychology ETDs

The well-documented tendency of people to be poor estimators of their relative abilities can be problematic in real life. These errors in are highly asymmetric: the worst performers dramatically overestimate their relative ability, whereas the best performers underestimate theirs (Kruger & Dunning, 1999). There are two possible causes of this misjudgment of relative ability: 1) participants are poor estimators of their own performance, or 2) participants are poor estimators of the comparison group’s performance. Kruger and Dunning (1999) attributed overestimation in the worst performers to the former problem but attributed the underestimation in the best performers to the latter problem. …

Pragmatic Measures In Aided Language Measurement: Aac Clinical Expert Perspectives, Makayla Hydiea Smith

Speech and Hearing Sciences ETDs

Purpose: The augmentative and alternative communication (AAC) discipline currently lacks psychometrically sound aided language measures. This thesis is designed to address one step in developing such measures: to begin to establish the clinical feasibility of three pragmatic measures – communicative intent, independence/co-construction, and imitation/non-imitation. Therefore, the objective of this thesis is to identify the useability of these pragmatic measures.

Method: A qualitative approach in the form of a focus group was used to examine the perceptions of SLP practitioners who are experts in AAC. Rapid qualitative analysis (RQA) was used to identify relevant themes and subthemes.

Results: Overall, the themes …

Improving Continuity Of Care: Evaluating Universal Nursing Handoff Sheets, Elizabeth Ifeloluwa Sanya

Doctor of Nursing Practice Scholarly Projects

Effective communication during nursing handoffs is essential for safe, patient-centered care, as breakdowns in communication are a leading cause of adverse patient outcomes. At a large academic level I trauma center, inconsistent nursing handoff practices were identified across progressive care units following the COVID-19 pandemic. This variability contributed to incomplete transfer of patient information and was associated with increased patient safety incidents, including delayed wound care, central line dressing lapses, and medication errors involving high-alert therapies. The purpose of this DNP project was to plan, implement, and evaluate the use of  standardized nursing handoff sheet and its impact on continuity …

Veribrief: A Multi-Agent Retrieval-Augmented Generation System For Policy Decision Support, Imane Bahji

Electrical and Computer Engineering ETDs

VeriBrief is a multi-agent retrieval-augmented generation (RAG) system for evidence-grounded economic policy analysis. The system orchestrates a five-stage LangGraph pipeline, retrieval, research, analysis, synthesis, and critique, to produce cited, structured responses while detecting out-of-scope queries. An empirical evaluation on eight questions drawn from official U.S. macroeconomic releases compared VeriBrief against a single-pass RAG baseline. The multi-agent system achieved 100% refusal precision on unanswerable analytical queries versus 0% for the baseline. Unsupported claims fell substantially on answerable factual questions. A context-propagation defect discovered during evaluation was diagnosed and corrected. Limitations include failure of the evidence gate on policy-counterfactual queries and a …

A Multimodal Analysis Of Conflicting Discourses On New Mexican Identity, Nicholas L. Chavez, Fátima Holguín

Intersecciones Hispánicas: Revista de Cultura, Literatura y Lingüística

We analyze two contrasting discourses on New Mexican identity, as represented in political cartoons from Trever (2021) and García (2018). We show how visual and linguistic elements of the cartoons work together to construct identity through metaphor and metonymy. It was found that Trever (2021) relied on cultural symbols such as the Zia Sun symbol as metonyms for various aspects of New Mexico’s identity, while García (2018) subverted established metaphors for American culture such as the melting pot and Uncle Sam to critique governmental influence on Nuevomexicano (‘New Mexican’) identity formation. Using the critical discourse analysis framework of Fairclough (1995), …

Misinterpreting Immigration Law, Michael Kagan

New Mexico Law Review

Although Congress bears primary responsibility for the convoluted nature of America’s immigration laws, immigration law has been rendered even more incoherent through inconsistent interpretation. During the reign of Chevron deference, the federal courts, the Board of Immigration Appeals and various Attorneys General pushed in different directions, with textualist, libertarian, and restrictionist impulses holding sway on different major interpretive questions. The result is that immigration law is more internally incoherent and more divorced from popular opinion than is necessitated by the text of the Immigration and Nationality Act. The end of Chevron deference offers some potential for the federal courts to …

Pixels And Property Rights: Resolving Social Media Ownership Disputes Between Employers And Employees Through Traditional Property Law Frameworks, Brittany Kjerstad Mcknight

New Mexico Law Review

Social media accounts have become valuable business assets, yet courts remain divided on how to resolve disputes over their ownership. In employer-employee contexts, some courts have adopted multi-factor tests to determine whether an account belongs to the business or the individual. However, these tests create inconsistent and unpredictable results, leaving businesses and employees uncertain about their rights. Courts should reject ad hoc multi-factor tests and instead rely on traditional legal frameworks, specifically property, contract, and agency law, to resolve social media ownership disputes. By treating social media accounts as non-transferable, revocable licenses governed by contractual terms, courts can apply established …

Into The Black Hole: Private Prison Contractors And The Inspection Of Public Records Act, August M. Ryan

New Mexico Law Review

The New Mexico Inspection of Public Records Act (IPRA) is a powerful mechanism for government transparency. Although private companies that contract with state agencies are subject to IPRA, the New Mexico Corrections Department and its contractors continually flout their IPRA obligations. Newsome v. Centurion Correctional Healthcare highlights a tension between IPRA’s robust enforcement provisions and its practical application to government contractors. The Newsome opinion, in denying access to records that should have been disclosed, struggles to articulate how public bodies, contractors, and designated records custodians interact under IPRA. This comment proposes an ordered, step-by-step approach to the custodian problem, seeking …

What’S Past Is Prologue: Prior Convictions As Evidence Of Dangerousness In State V. Romero, Alexander Guel-James

New Mexico Law Review

State v. Romero marked the first time the New Mexico Court of Appeals considered whether a New Mexico law disarming every person with a state felony conviction was unconstitutional under the Second Amendment. The court upheld the law, but only to the extent that it disarmed dangerous felons. The court found that the appellant was dangerous because he was previously convicted of dangerous crimes. This note questions whether prior convictions alone are sufficient to prove dangerousness. Criminal justice data and constitutional theory caution against dangerousness findings based on criminal history alone. Courts should determine dangerousness under the disarmament law using …
