Higher Education Instructors’ Perspectives On The Challenges Of Implementing Competency-Based Learning In Coursework, Sammie Leo Davis Jr

Walden Dissertations and Doctoral Studies

Higher education instructors face challenges in implementing competency-based learning (CBL) in their coursework. Grounded in Vygotsky’s social constructivist theory, the purpose of this basic qualitative study was to explore the perspectives of higher education instructors on the challenges and their needs to implement CBL in coursework. For this basic qualitative design, semistructured interviews were conducted with 12 higher education instructors who had at least 2 years of experience teaching CBL courses. Data were analyzed using qualitative content analysis and inductive coding to identify codes and categories, with the following five themes emerging: CBL implementation depends on (a) aligned assessment, curriculum …

Spatiotemporal Analyses Of The Biological Condition Gradient (Bcg) For Florida’S Coral Reef, Maya Becker

All HCAS Student Capstones, Theses, and Dissertations

A conceptual model known as the Biological Condition Gradient (BCG) was originally constructed for biological assessments and has recently been adopted for use on Florida’s coral reef after repeated anthropogenic stressors have been linked to declines within the state of the reef. Anthropogenic pressures have reduced water quality, exacerbating coral disease and associated mortality disrupting ecosystem services and biological function throughout Florida’s coral reefs (FCR). The intention of the BCG model is to assess biological condition against increasing levels of anthropogenic stress and to identify biological attributes and measurable increments of change from long term monitoring data. Differences in spatial …

Process From Noise: Erosion Threshold Variability And The Morphology Of Gravel-Bed Rivers, Robert Paul Kostynick

Arts & Sciences Graduate Student Theses and Dissertations

Rivers are remarkably consistent as their geometry, width, depth, and slope change systematically downstream in response to differences in fluid discharge and sediment transport throughout a channel. Rivers move both water and sediment through terrains that depend on these downstream geometric adjustments influencing water quality, ecology, infrastructure, channel morphology, and landscape evolution at increasing timescales respectively. Rivers thus influence all aspects of life and define our spatial landscapes that shape boundaries, whether physical, politically, or socially. Nevertheless, a river is dynamic and does not adhere to human-defined boundaries, making it vital that we understand how these features change over time …

Building A Culture Of Trust: Engaging Teams With Targeted Tactics For Meaningful Improvement In Patient Experience, Anna Buckner, Kimberly Lewis

Patient Experience Journal

Rising financial pressures and the need to revitalize culture prompted a renewed emphasis on patient experience at Billings Clinic. This case study describes the impact of redefining patient experience as a measure of trust and a set of care processes. It presents an alternative to the more traditional view of patient experience as an outcome metric based on meeting patient expectations. Billings Clinic chose the patient survey question likelihood of recommending as an organizational goal or key performance indicator (KPI). Under the direction of executive leadership, the patient experience team developed a new strategic framework aimed at driving improvement for …

Non-Linear Semantic Navigation In Large Language Models Via Matrix Operators, John Chang

Defensive Publications Series

Current conversational interfaces for large language models rely on linear interactions. This linear approach restricts information retrieval and causes navigational context to be lost. Lengthy text inputs are required to refine search spaces, leading to semantic pollution. To address these limitations, a non-linear semantic navigation method is disclosed. User intent is captured through a visual query tree and mapped directly to projection matrices. Specific matrix transformations are applied to local vector regions within a high-dimensional embedding space. These operations rotate, scale, and project the semantic space to amplify specific latent dimensions without requiring lengthy text inputs. Irrelevant branches are mathematically …

An Adaptive Geometric Vector Encoding Language And Spatial-Harmonic Compiler For Topological Computing Engines, Christopher L. Eckes

Defensive Publications Series

This disclosure establishes a non-textual, multi-dimensional machine language and compiling framework optimized for two-dimensional quantum fluid and topological computing substrates. By replacing linear, binary assembly instruction sets (e.g., QASM) with spatial-harmonic vector topologies, programming commands are encoded directly as geometric phase deformations and wave-packet configurations. A bi-directional, reversible semantic compiler architecture is defined to eliminate information erasure latency and satisfy thermodynamic zero-emission constraints during algorithmic runtime execution.

Pipeline-Based Data Processing Method, System, And Hardware Apparatus, Jinhui Wu

Defensive Publications Series

Existing data processing systems universally adopt a centralized computing paradigm that relies on
complex operations, resulting in high computational resource consumption and significant bandwidth
redundancy. This paper proposes a data processing method, system, and hardware apparatus based on a
Pipeline Array, wherein input data is distributed across multiple independent Pipelines. Each Pipeline
independently maintains a state value, compares the input against its state, outputs upon change, Blocks
when unchanged, and independently updates its state value. Founded on the Zero-Computation Property
(core operations are comparison and assignment only), the system comprises Pipeline, State Storage,
Compare, Output Control, and State Update modules. …

A Fluid-Dynamic Architecture For Topological Qubit Protection Against Phononic Decoherence, Christopher L. Eckes

Defensive Publications Series

This disclosure formalizes a non-particle engineering framework for stabilizing quantum states against environment-induced decoherence using topological surface harmonics. By reinterpreting qubits as localized vertical tension fields on a discrete two-dimensional information fluid substrate (\(z=0\)), phase stability is established via passive geometric vortex compaction and time-periodic (Floquet) symmetry protection fields rather than active physical isolation. Real-world laboratory verification testing protocols using fractional quantum Hall two-dimensional electron gases (2DEGs), topological acoustic metamaterials, and cascaded superconducting waveguides are explicitly defined to provide prior art for scalable quantum computing architectures.

Feasibility And Performance Of Aerogravity Assists For Ceres Missions, Divinaa E. Burder

International Journal of Aviation, Aeronautics, and Aerospace

This work investigates the feasibility and performance of aerogravity assist (AGA) maneuvers for missions to Ceres, with emphasis on both interplanetary trajectory design and atmospheric flight dynamics. AGAs provide substantially greater turning capability than pure gravity assists by exploiting aerodynamic lift during atmospheric passes, thereby enabling greater heliocentric energy changes than pure gravity assists. To quantify these benefits, this study integrates a broad interplanetary trajectory search with high-fidelity atmospheric performance modeling. Candidate trajectories for launch years 2030–2050 are generated for multiple inner-planet encounter sequences using vehicles with lift-to-drag ratios (L/D) between 1 and 7. Atmospheric flight segments are simulated using …

Assessing And Addressing Financial Risk In Capitated Primary Care Contracts, Michael R. Wieck Dba, Laurence Smith, Steven R. Stout Dba

Engaged Management ReView

We employ multivariate statistical modeling and Monte Carlo simulation to study systematic and unsystematic financial risk faced by physician groups under capitated contracts with Medicare Advantage Organizations (MAOs). We use mixed methods and a standard reimbursement formula for risk-sharing contracts with primary care physicians (PCPs). We find that diversifying risk simply by increasing the size of a practice is insufficient to mitigate risks of large negative cash flows from capitation contracts and can result in financial failure. However, if use of costly medical services by patients is reduced from levels typically experienced under traditional Medicare to the levels of patients …

Characterizing Candidate Blazar Counterparts Of The Ultra-High-Energy Event Km3-230213a, O. Adriani, S. Aiello, A. Albert, A. R. Alhebsi, M. Alshamsi, S. Alves Garre, S. Rani, Et Al.

The neutrino arrival direction has a 99% confidence region of 3° radius centered at R.A. 94 (Formula presented) .° 3, decl. −7 (Formula presented) .° 8 (J2000). In this work, 17 candidate blazars located within this region are identified. Comprehensive new observations and archival data analysis for these sources are presented. …

Fraction-Seq: An Integrated Experimental And Computational Workflow For Determining The Localization And Abundance Of Small Non-Coding Rnas In Subcellular Compartments, Siddhartha Shah, Tess Cherlin, Yi Jing, Stepan Nersisyan, Benjamin E. Leiby, Isidore Rigoutsos

Computational Medicine Center Faculty Papers

Small non-coding RNAs (sncRNAs) have garnered considerable attention in recent years, following accumulating evidence of their critical roles in many cellular processes. Among sncRNAs, microRNAs (miRNAs) and their isoforms (isomiRs), tRNA-derived fragments (tRFs), rRNA-derived fragments (rRFs), and Y RNA-derived fragments (yRFs) account for more than 95% of all sncRNAs found in cells. Despite their critical regulatory roles, most sncRNAs remain uncharacterized because their functionalization is a lengthy and challenging undertaking. Knowing an sncRNA's abundance helps prioritize among the various choices, while knowing where it localizes in the cell greatly limits the number and identity of its potential targets and helps …

Findings highlight the role of targeted preparation and field-based experiences in supporting inclusive teaching readiness.

Modeling Formation Of Turbulent Sporadic-E Clouds Using Realistic Wind Data, Aaron M. Schinder, Kenneth S. Obenberger, Jorge L. Chau, Juan M. Urco, Matthias Clahsen, Benjamin F. Akers, Daniel J. Emmons

Faculty Publications

A high resolution two-dimensional multi-fluid model of sporadic-E layers was developed and driven with physically realistic mesosphere, lower thermosphere (MLT) winds measured over Albuquerque, New Mexico. The realistic E-region winds are produced by the HYdrodynamic Point-wise Environment Reconstructor (HYPER) model that ingests meteor derived wind observations from a Spread-spectrum Interferometric Multistatic meteor radar Observing Network (SIMONe) system combined with the Navier-Stokes equations to provide high resolution three-dimensional wind fields over time. Sporadic-E dynamics are simulated using both realistic winds from HYPER as well as idealized hyperbolic tangent windshears to compare and contrast. Overall, the model shows greater inhomogeneity and irregularity …

Department of Physics and Astronomy Faculty Scholarship and Creative Works

Our understanding of the weak mixing of quarks, described by the Cabibbo-Kobayashi-Maskawa (CKM) matrix, currently presents an anomaly. Thanks to major strides in both theory and experiment, improved precision in determinations of the first row of matrix elements has revealed disagreement with the expectation of unitarity. The Nab experiment at the Spallation Neutron Source is designed to precisely extract the first matrix element Vud and shed light on experimental tensions within the neutron beta decay dataset. Nab’s asymmetric spectrometer allows coincident reconstruction of the decay proton and electron energies, which will be used to determine the electron-neutrino correlation coefficient, and …

Gwtc-4.0: Constraints On The Cosmic Expansion Rate And Modified Gravitational-Wave Propagation, The Ligo Scientific Collaboration, The Virgo Collaboration, The Kagra Collaboration, Marc Favata, Shoan Ghosh, Rodica M. Martin

Department of Physics and Astronomy Faculty Scholarship and Creative Works

We analyze data from 142 of the 218 gravitational-wave (GW) sources in the fourth LIGO–Virgo–KAGRA Collaboration (LVK) Gravitational-Wave Transient Catalog (GWTC-4.0) to estimate the Hubble constant H0 jointly with the population properties of merging compact binaries. We measure the luminosity distance and redshifted masses of GW sources directly; in contrast, we infer GW source redshifts statistically through (i) location of features in the compact object mass spectrum and merger rate evolution, and (ii) identifying potential host galaxies in the GW localization volume. Probing the relationship between source luminosity distances and redshifts obtained in this way yields constraints on cosmological parameters. …

Who Owns Land, Who Owns Language? Challenging The Commercialization Of Indigenous Language Data, Matthew Riemland

Maya America: Journal of Essays, Commentary, and Analysis

As Indigenous scholars and activists have pointed out, the commercialization of Indigenous language data resembles the historical and ongoing dispossession of Indigenous land. Using Mayan languages as a case study, this article illustrates the process by which digital advertising platforms – Google and Meta – appropriate and benefit commercially from Indigenous language data, drawing parallels with the dispossession of Indigenous land. It identifies the significant costs of this commercialization to Indigenous communities, including the lack of compensation for the Indigenous language data’s commercial value, the distortion of Indigenous communities’ linguistic and cultural representation online, and the reinforcement of extractive relationships …

The study examines students’ understanding and misunderstanding of what constitutes culturally responsive teaching. This is a mixed methods study. A Likert-type survey and qualitative questionnaires were used to collect data. Descriptive statistics were used to analyze survey data, and a thematic coding method was used for analysis of qualitative data. The results of the study show that pre-service teachers are aware and knowledgeable of the term culturally responsive teaching as the term is widely used in the teacher education program in which they were …

Assessing The Impact Dynamics Of Less Lethal Ammunition, Steven Bermejo

Student Theses

Less-lethal ammunition is widely used by law enforcement as an alternative to lethal force during crowd control, on-street confrontations, and other situations requiring force. Although these projectiles are intended to reduce risk of fatal injury, serious injuries and fatalities have been reported, highlighting the need to better understand the factors that influence their impact behavior. This study evaluated the impact dynamics of four types of 12-gauge less-lethal ammunition, including rubber buckshot, single rubber ball, double rubber ball, and Byrna kinetic projectile, using kinetic energy calculations derived from projectile mass and velocity measurements. In addition, Attenuated Total Reflectance Fourier Transform Infrared …

Dry After-Ripening Increases Germination Of Critically Imperilled Physaria Thamnophila (Zapata Bladderpod), Christopher A. Gabler, Jerald T. Garrett

School of Earth, Environmental, & Marine Sciences Faculty Publications

Effective endangered plant conservation and recovery require empirical knowledge of seed dormancy release and responses to post-collection handling, yet such information is lacking for many rare taxa. Physaria thamnophila (Zapata bladderpod; Brassicaceae), a critically imperilled (G1) species endemic to southern Texas, USA, is poorly studied, and basic questions regarding seed storage and germination remain unresolved. We evaluated the effects of short-term cool-storage duration (14–180 d), storage temperature (refrigeration vs. freezing), dry after-ripening and maternal plant identity on germination probability and timing in P. thamnophila. Dry after-ripening and increased cool-storage duration consistently increased germination and shortened germination time, whereas storage temperature …

Real Bullets, Plastic Guns: Evaluating The Strength Of 3-D Printed Gun Parts, Maria Latenia Mayol

Student Theses

Privately made firearms (PMFs), often referred to as “ghost guns,” are firearms manufactured or assembled by individuals rather than federally licensed manufacturers. Although the terms are frequently used interchangeably, “ghost gun” more specifically describes an unserialized firearm, whereas PMFs include a broader range of firearms produced through nontraditional manufacturing methods. PMFs may be entirely 3-D printed, assembled from partially completed firearm kits, or constructed by integrating additively manufactured components with commercially manufactured firearm parts. The increasing accessibility of additive manufacturing and widespread dissemination of computer-aided design files have raised concerns about concealment, regulation, and forensic evasion, particularly when factory-manufactured components …

Accelerometer-Based Longitudinal Center Of Gravity Estimation With Lateral Acceleration Compensation, John Wynne

Theses

Spatially separated accelerometers and measured rotational motion can enable estimation of an aircraft’s longitudinal center-of-gravity (CG) location. Because the unrestricted rigid-body governing equations form an underdetermined system, the problem is reduced by assuming known lateral and vertical CG coordinates. The resulting estimator uses the lateral acceleration equation, where sensitivity to longitudinal CG is governed by the rotational excitation term 𝑀_21 = 𝑝𝑞 + 𝑟̇. Three representations of lateral acceleration at the CG are evaluated: a zero- acceleration assumption, a linear sideslip angle model, and a model based on sideslip angle and true airspeed squared. Each model is calibrated using known …

The Computed Microwave Spectrum Of The Protonated Fullerene C60H+, Laszlo Nemes, Jos Oomens, Vincent J. Esposito, Vincent Boudon, Alexander G. G. M. Tielens

Biology, Chemistry, and Environmental Sciences Faculty Articles and Research

The largest known molecule in the interstellar medium of galaxies, C₆₀, has been detected in its neutral and cationic form through its vibrational, UV-driven fluorescence emission spectrum and its electronic absorption spectrum, respectively. The detection of several polycyclic aromatic hydrocarbon molecules through their pure rotation spectrum in cold, dense, molecular cloud cores suggests that C₆₀ might be present in these environments as well. The low flux of UV pumping photons in molecular cloud cores and the absence of suitably bright background stars, make detection of C₆₀ and its cation through the commonly used methods impractical. As …

The 2025 Measles Outbreak In Texas, Tamer Oraby, Martial L. Ndeffo-Mbah

School of Mathematical & Statistical Sciences Faculty Publications

Background: In 2025, Texas experienced its largest measles outbreak in decades, reporting 762 cases by mid-August. Measles is a highly contagious but vaccine-preventable infection transmitted mainly among unvaccinated individuals and capable of causing severe outcomes.

Methods: We investigate counterfactual measles control scenarios based on daycare and school closures and reactive vaccination of infants and children, including mixed interventions. We analyze the 2025 Texas outbreak using an age-structured multi-stage SEIR model formulated as a system of ordinary differential equations. The model is fit to case data using Bayesian inference to estimate the effective reproduction number and generate posterior predictive trajectories under …

Teleportation Game: Quantum Teleportation In Multi-Agent Systems For Interactive Music, Eduardo Miranda

School of Art, Design and Architecture

This paper introduces an interactive music system with quantum musical agents that communicate by teleporting quantum states to one another. Human performers interact in real time with agents whose melodic and rhythmic behaviours are encoded as quantum states using Single Qubit Probability Amplitude Modulation (SQPAM) and structured through Quantum Phase Estimation (QPE). Up to three agents are combined within a single quantum circuit, with directed communication via quantum teleportation. We are interested in supporting ambiguous, transformative interactions reminiscent of free Jazz improvisation. Therefore, rather than treating noise and decoherence as limitations, the system embraces NISQ-era constraints as creative affordances, framing …

A Granularity-Centered Taxonomy Of Personalized Federated Learning, Ei Ei Nyein Chan, Sergei Chuprov, Pretom Roy Ovi, Kamrul Hasan

Computer Science Faculty Publications

Personalized Federated Learning (PFL) has emerged as a key approach to address performance degradation in FL systems under heterogeneous client data. While existing surveys typically categorize PFL methods based on optimization strategies or system-level mechanisms, they often overlook a fundamental question: where is personalization embedded within the model architecture? In this survey, we bridge this knowledge gap and introduce a granularity-centered taxonomy that organizes PFL approaches according to the structural depth of personalization, ranging from head-layer and layer-wise adaptation to model-wise and parameter-wise customization. This novel perspective helps practitioners select appropriate personalization strategies based on model architecture, data heterogeneity, and …
