Finally, …

Brain-Based Mechanisms Of Behavioral Impairment In Fetal Alcohol Spectrum Disorder (Fasd): The Neuroimaging Biomarkers Of Inhibitory Control, Zinia Pervin

Biomedical Engineering ETDs

The developing brain is highly susceptible to alcohol-induced toxicity, often resulting in long-term deficits in executive function and behavioral regulation. Inhibitory control impairments are among the most prominent deficits observed in Fetal Alcohol Spectrum Disorder (FASD). This study investigated the neural mechanisms of inhibitory dysfunction using a multimodal MEG–DTI approach in 67 children aged 6–8 years (34 with FASD, 33 controls) who performed a Go/No-Go task. Source-level MEG analyses revealed reduced stimulus-locked cortical activation in the anterior cingulate cortex and significant group-by-hemisphere interactions in the superior parietal cortex and cuneus. Time–frequency analyses showed diminished response-locked beta power in the sensory-motor …

Policy Concerning Student Use Of Magnification Loupes By American Dental Hygiene Schools, Amye M. Burruss

Dental Hygiene ETDs

This descriptive study was to assess whether dental hygiene schools require students to purchase magnification loupes, at what point in the program they implement the use of loupes, and which type of loupes they require students to purchase. A survey link through Microsoft Forms consisting of nineteen multiple-choice questions was emailed to 327 dental hygiene program directors and was open for a total of three weeks. With a response rate of 13% (45 respondents), results indicate that most dental hygiene programs mandate or strongly encourage the use of magnification loupes and allow students to start wearing loupes in the first …

Drawing on the Hierarchy of Influences and Social Responsibility Theory, the study uses ethnographic content analysis by analyzing (n=104) articles between 2022 and 2025 to examine framing, source usage, tone, and emphasis. Findings indicate that The New York Times more frequently framed climate change through political and economic lenses and relied heavily on government and business sources. In contrast, The Guardian more often employed scientific framing, cited researchers, …

Blockade Logic: Settler Consciousness And The Petro-Security Apparatus, Sarah Seroy

Communication ETDs

This study examines contemporary CID legislation and surrounding political rhetoric in Canada and its implications for Indigenous communities. It reveals how settler consciousness is affirmed through such legislation and how discourse rooted in colonial logics serves to strengthen Canada’s petro-security apparatus. Drawing from Teun van Dijk’s (1995) method of Ideological Discourse Analysis and integrating Indigenous epistemologies, it offers a research approach of anticolonial discourse analysis. This analysis reveals CID legislation as a racialized, colonial tool and a form of biopower the settler-state exerts over Indigenous communities. It normalizes settler-state hegemony and justifies the ongoing dispossession of Indigenous communities. This study …

Mapping Homogeneous Configuration States For Learning Based Motion Planners, Yazied Hasan

Computer Science ETDs

Reinforcement learning (RL) excels at solving complex tasks, but training times can become prohibitively large for challenging motion-planning problems. Methods that address this cost often require additional training or tuning, counteracting the goal of reducing training time. A more effective approach is to exploit inherent task equivalences: many elements of the state space, dynamics, or structure are functionally interchangeable, enabling simplification or knowledge reuse. We present learning solutions that leverage these equivalences to enhance the RL process. First, we leverage the symmetry of homogeneous multi-agent teams to simplify the task to a single strategy. Second, we map correspondences between distinct …

Identification Of Aortic Centerline Shape Features, Bebel B. Trani

Mechanical Engineering and Materials Science Independent Study

Better predictions of the likelihood of an aortic event in patients are paramount to providing quality care in medicine. Ascending aortic aneurysms (AsAA) are typically asymptomatic until sudden complications, such as rupture or dissection, occur and are often fatal [1]. As a form of preventative care, physicians identify and monitor high-risk patients. Surgical interventions are also performed for high-risk patients, replacing the weakened segment of the ascending aorta before a catastrophic event occurs. Determining which patients require surgical intervention or close monitoring is therefore extremely important. These decisions are largely guided by maximum diameter measurements; for the ascending aorta, a …

tests) examined statewide enrollment data (2017-2025) to determine whether significant

differences exist between Year 1 and Year 4 cohort enrollment. Qualitative analysis was

conducted through a deductive discourse analysis of Western Association of Schools and

Colleges (WASC) Self-Study reports …

Stochastic Derivative-Free Deep Learning Methods For Solving High Dimensional Partial Differential Equations, Qing He Mr.

Mathematics Theses and Dissertations

Solving high-dimensional partial differential equations (PDEs) is a fundamental challenge in scientific computing, with applications ranging from quantum chemistry and computational finance to statistical physics and stochastic optimal control.  Classical numerical methods such as finite element or finite difference schemes suffer from the curse of dimensionality, rendering them computationally infeasible when the dimension $d$ exceeds a handful. Physics-informed neural network (PINN) methods alleviate this by embedding the PDE residual directly into a loss function, but they require computing derivatives of the network with respect to its spatial inputs---an operation that scales poorly in high dimensions and demands that the approximate …

Post-Fire Flood Modeling In Ruidoso, New Mexico: Improving Burn Scar Runoff Predictions, Pramesh Bhaila

Civil Engineering ETDs

Recent large wildfires in New Mexico have demonstrated severe hydrological driven by vegetation loss and the development of hydrophobic soil surfaces. This thesis evaluates the performance of three infiltration models—Curve Number (CN), Linear Constant (LC), and Green–Ampt (GA)— for the watershed impacted by the 2024 South Fork and Salt Fires near Ruidoso, New Mexico. All three models performed comparably during post‑fire simulations, with strong performance in 2024 and notable degradation in 2025, particularly for the CN. Post-fire analyses indicate substantial reductions in infiltration capacity, with CN increasing by 18–24%, LC initial deficit decreasing by 65–77%, effective hydraulic conductivity reduced by …

Investigating Workforce Development Gaps In Tribal Transportation Agencies, Benson Long Jr

Civil Engineering ETDs

Tribal transportation programs face challenges in recruiting and retaining qualified staff, prompting reliance on external consultants for key responsibilities. This study explores how workforce constraints and organizational structures influence tribal outsourcing decisions. Survey data from 57 tribes informed a logistic regression model examining how geographic isolation, population size, training access, and the presence of a transportation department affect preferences for internal work, actual task completion, and instances where tribes intended to perform tasks in-house but outsourced instead. Findings indicate that outsourcing is driven by limited internal capacity, including staffing shortages, lack of certified personnel, and training opportunities. Geography also plays …

Development Of A Lead-Lithium Eutectic Magnetohydrodynamic Loop For Corrosion Studies, Xavier S. Angus

Nuclear Engineering ETDs

Lead–lithium eutectic (LLE) is a leading candidate coolant and tritium breeder for fusion reactor blankets due to its favorable heat transfer properties and high tritium breeding ratio. However, LLE is highly corrosive and, in the strong magnetic fields present in fusion reactors, experiences magnetohydrodynamic (MHD) effects that can produce significant pressure drops and flow instabilities. Understanding corrosion behavior in these extreme environments is essential for assessing the viability of LLE blanket systems. This work presents the design and construction of a forced-convection LLE corrosion loop to study corrosion behavior at temperatures up to 425 °C and flow velocities up to …

The TTHX was first designed and assessed using a MATLAB-based framework, followed by detailed MELCOR simulations. The results demonstrate effective heat transfer …

Sensitivity-Informed Resonance Parameter Cross Section Adjustments, Matthew Juan Lazaric

Nuclear Engineering ETDs

This work details the process of developing several new features into the MCNP6.3 Monte Carlo code for use in uncertainty quantification and reduction. These new capabilities, which include the CLUTCH method of calculating k-eigenvalue cross section sensitivities and the Windowed Multipole method of calculating cross sections, are implemented and verified against previous implementations and existing cross section data, respectively. These capabilities are then combined to produce sensitivities of k-eigenvalue to resonance parameters, which are verified against direct perturbation sensitivity estimates. The resonance parameters are calibrated using linear Bayesian methods and the accuracy of the resulting cross section is evaluated via …

Representativeness And Sensitivity Analysis Of Accident Tolerant Fuel Cladding Behavior In Reactivity-Initiated Accidents, Melissa Andrea Moreno

Nuclear Engineering ETDs

Accident Tolerant Fuels (ATFs) such as FeCrAl are being developed to enhance safety margins in light water reactors during transients like Reactivity Initiated Accidents (RIAs). This dissertation evaluates the accuracy and representativeness of TRACE thermal hydraulic models for predicting FeCrAl C36M cladding behavior under steady state and transient flow boiling conditions. Benchmarking against University of New Mexico separate effects experiments shows that TRACE reproduces key thermal trends but underpredicts cladding temperatures near CHF by approximately 25 to 30%. A calibrated uncertainty and global sensitivity analysis, using Sobol indices, demonstrates that CHF and cladding temperature variability are dominated by mass flux, …

Lowering Class Size To Improve Teaching And Learning Mathematics In Early Grades, Dianne S. Mccarthy

Journal of Inquiry and Action in Education

Fourth-grade mathematics proficiency in the United States remains low, with only 39–57% of students meeting proficiency standards on NAEP, New York State, and TIMSS assessments. This article argues that reducing class sizes in the early grades (K–3) is an effective strategy to improve teaching and learning in mathematics. Evidence from the Tennessee STAR study and supporting research (Clanet, 2010; Cho et al., 2012) shows that smaller classes yield statistically significant and lasting gains in student achievement. Benefits include stronger teacher-student relationships, increased individualized attention, fewer disruptions, and more active student engagement. These conditions enable high-impact, constructivist approaches such as inquiry-based …

Reining In The Patent Troll: Lessons The United States Can Learn From Its Northern Neighbors, Megan Petras

Loyola of Los Angeles International and Comparative Law Review

In patent law, non-practicing entities (NPEs) are patent holders who do not practice their patented invention. In recent years, there has been concern over a particular type of NPE, the patent troll. Patent trolls are said to harm innovation because they do not come up with any new ideas themselves, but instead buy up patents cheaply, find potential infringers, and threaten litigation to receive large settlements or damage awards. Interestingly, the patent troll problem is considered to be primarily a problem in the United States. While comparisons have been made between the existence of patent trolls in the European Un-ion …

International Human Rights Law And Extrajudicial, Summary Or Arbitrary Execution In Africa, John Mukum Mbaku

Loyola of Los Angeles International and Comparative Law Review

International and regional human rights instruments, as well as the laws of many countries, including those in Africa, consider the right to life to be a very important and fundamental human right. Human rights defenders believe that without this right, individuals cannot enjoy or realize the other rights and fundamental freedoms that are guaranteed by and enshrined in international and regional human rights instruments, as well as in many national constitutions. However, despite the protections granted to the right to life by both international and domestic laws, it remains threatened by many individuals and groups. Threats to the right to …
