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 …

Load Balancing Algorithms For Cloud Computing Systems, Mark Rakesh Christian

Electronic Theses and Dissertations 2020 - Present

Cloud computing depends on load balancing to allocate user requests among virtual machines (VMs), affecting response time, utilization, and scalability. Round Robin, Equally Spread Current Execution, and standard Throttled scheduling are widely used; however, standard Throttled selects among eligible VMs using an implementation-dependent order with no explicit preference. This thesis proposes the Weighted Throttled Load Balancing (WTLB) algorithm, which introduces an explicit, deterministic selection priority among eligible VMs, implemented by modifying the Throttled scheduler within CloudAnalyst.

Evaluated under an identical six-region, multi-data-center configuration against Round Robin, ESCE, and standard Throttled, WTLB preserves the aggregate response-time, processing-time, and cost profile of …

Clinicopathologic Spectrum Of Renal Disease In Sars-Cov-2 Infection And Post-Covid-19 Vaccination, Naya Williams, Mohammed S. Razzaque

School of Medicine Publications

Both SARS-CoV-2 infection and COVID-19 vaccination have been associated with renal complications. In the context of SARS-CoV-2 infection, kidney injury is primarily attributed to a complex interplay of systemic immune dysregulation and vascular damage. Severe infection triggers a cytokine-mediated inflammatory response characterized by elevated levels of pro-inflammatory mediators, resulting in systemic hemodynamic instability, increased capillary permeability, and renal hypoperfusion, ultimately leading to acute tubular injury. In addition, virus-induced endothelial activation promotes a prothrombotic state, microvascular injury, and further impairment of renal perfusion. Collectively, these processes converge to produce acute kidney injury (AKI) and, in severe or prolonged cases, may contribute …

The Mediating Role Of Moral Disengagement In The Relationship Between Facets Of Empathy And Aggression, Romiere J. Horace

Theses

Aggression is a major social and public health concern with economic, psychological, and interpersonal implications. Extensive research has examined the potential antecedents for aggressive behavior, with many different environmental, biological, and intrapsychic factors being significantly associated with aggression. Researchers have also focused on cognitive mechanisms, like empathy, as a protective factor for aggression. More specifically, research has linked lower levels of empathy to higher levels of aggression; however, the underlying mechanisms of this relationship remain underexplored. A potential explanatory mechanism is moral disengagement, which allows individuals to justify harmful behaviors and avoid self-sanctions. However, limited research has examined these constructs …

The Dynamic Interplay Between Agency Costs And Whistleblowing: Evidence From West African Banks, Titilayo Moromoke Oladejo Dr.

Arab Economic and Business Journal

Agency issues have been a significant issue of governance in banks, particularly in the emerging economies where information asymmetry and ineffective monitoring mechanisms allow managerial opportunism. In West Africa, banking crises are common and are associated with excessive insider lending, ineffective board supervision and internal controls, which highlights the importance of more effective governance mechanisms. This paper examines the two-way relationship between the agency costs (AGC) and whistleblowing (WBH) in listed banks in Nigeria and Ghana. The analysis is based on panel data from 2017-2024 and a two-step System GMM, which adjusts the endogeneity and dynamic effects and estimates the …

A Charles Williams Diptych: G. M. Hopkins And T. S. Eliot, Eric Rauscher

Mythcon

This presentation consists of two short papers touching upon an interest of mine in the development of Williams' poetry.  In the first paper about Hopkins I argue for a direct influence that played a role in the transition from Williams' early poetry to his late Arthurian poems.  The second paper dealing with Eliot tangentially addresses a similar influence, but in a much more nuanced fashion. Here I am only offering hints. I am quite sure there are many other avenues of study for the transformation from his early poetry to his later mature style which is a poetically complex style …

“It’S Its Own Toxic”: Occupational Opportunities And Barriers For Lgbq+ Collegiate Athletic Administrators, Colleen S. O'Connell, Michelle E. Moosbrugger, Jill Kochanek, Elizabeth M. Mullin

Journal of Issues in Intercollegiate Athletics

Athletic administrators hold positions of influence within intercollegiate sport, yet their experiences, especially in relation to sexual identity, remain underexamined. The purpose of this study was to explore the occupational experiences and environments of LGBQ+ intercollegiate athletic administrators using a narrative inquiry qualitative design. Sixteen administrators, who occupied various positions across all NCAA levels, were interviewed. Guided by Sexual Stigma and Prejudice Theory and Poststructuralism Theory, collected data were analyzed at the semantic and latent levels using reflexive thematic analysis. Two distinct themes were generated: LGBQ+ administrators described both positive and negative aspects of their workplaces. Inclusive environments were committed …

Our Journeys As Teachers Of Writing: Learning From Our Mentor, Tracey T. Flores, Cecilia Espinosa

Teaching/Writing: The Journal of Writing Teacher Education

Written in two voices, we reflect on our journeys as teachers of writing and teacher educators shaped by transformative mentoring in literacy methods courses at Arizona State University and community embedded learning at William T. Machan School. Weaving together sociocultural and translanguaging theories, we explore how being invited to write from our lives reshaped our identities as writers and educators. In our work, we draw on strength-based approaches to teaching writers that centers voice, meaning making, multilingualism, and funds of knowledge. In the midst of an increase in the use of a scripted curriculum, we argue for reclaiming writing as …

Strengthening Our Pedagogy Together: A Methods Instructor And Her Former Student Partner To Promote Agency In The Secondary Writing Classroom [Special Issue], Michael Rojas, Kate Sjostrom

Teaching/Writing: The Journal of Writing Teacher Education

In many English classrooms today, writing instruction is reduced to templates and formulas, robbing students of agency, voice, and transferable skills. This article describes a collaboration between a writing methods course instructor and one of her former students bent on proving that what they believe makes for solid writing instruction—a sometimes messy process involving choice and authentic purpose and audience—works. Documenting development of a new secondary writing course and a project to introduce the course’s methods to pre-service teachers, the authors recount barriers they encountered, strategies they developed for overcoming them, and issues they are still grappling with. In the …

Teaching/Writing: The Journal of Writing Teacher Education

In this article two teachers and their writing methods professor explore the challenges of the traditional methods course. In sharing the teachers’ experiences of retaking the methods course, they argue for the need to consider ways that practicing teachers can revisit the methods course to develop sustainable practices for the teaching of writing in secondary schools.

Expertise, Ideals, And The Ecology Of Learning To Teach: A Conversation About The Transition From The Writing Methods Course To Student Teaching [Special Issue], Jessica Rivera-Mueller, Josie Clark

Teaching/Writing: The Journal of Writing Teacher Education

Writing pedagogy educators need approaches for designing the writing methods course in ways that will make a positive impact on practicing teachers’ decision-making. In this article, the co-authors—a writing pedagogy educator and a former student—address this need by providing a reflective conversation about the former student’s transition from the writing methods course to the student teaching experience. Together, the co-authors explore the extent to which a hands-on learning experience built into the writing methods course (designing and hosting an online writing competition for middle and high school students) impacted the former student’s experience of teaching writing as a student teacher. …

From Corrector To Reader: Pre-Service Teachers’ Writing Values And Feedback, Amanda Brewer

Teaching/Writing: The Journal of Writing Teacher Education

This study investigates the written feedback practices of secondary English Pre-Service Teachers (PSTs) to understand how their values regarding "good" writing influence their comments on student work. Through analysis of feedback on 10th-grade writing samples and value-sorting surveys, the study examines their feedback tendencies and the links with their values. Findings indicate a significant shift over the semester from a directive, deficit-based "corrector" stance to a facilitative, asset-based "reader" stance. The data suggests that when PSTs lack specific metalinguistic language, they default to generic advice or mechanical correction. However, when instructed to align their feedback with their core writing values, …

Execution Of Browser Agent Tasks Using Event-Based And Time-Based Triggers, Akancha Murlidhar Gupta

Defensive Publications Series

A browser agent system is utilized for executing browser-based tasks responsive to temporal triggers, event triggers, or combinations thereof. The system receives a task request associated with a future action and stores a task definition including execution parameters, user preferences, authentication information, and browser-session context. A trigger-monitoring subsystem evaluates trigger conditions, including scheduled events, recurring schedules, notifications, price changes, availability changes, webpage changes, and other detectable events, and initiates execution when a trigger condition is satisfied. To enable execution when a browser application is inactive or closed, the system restores previously stored browser-session context and launches an execution environment locally …

Automated Synthesis Of Verifiable Automation Packages From Interactive Session Telemetry, Romek Rutowski, Piotr Nalewajko, Paramesh Manickavelu

Defensive Publications Series

A challenge in systems management can be converting workflows from interactive, non-deterministic sessions with agentic systems into reusable automation, as some methods may involve manual refactoring or produce scripts with environmental dependencies. An automated pipeline can ingest unstructured session telemetry, such as command logs, and programmatically synthesize a structured and self-contained software package. For example, the system can distill a sequence of operations, perform dependency resolution to create executable commands, flatten logic for portability, and generate a validation suite based on the original session's outputs. This process can convert an ephemeral workflow into a more deterministic and portable asset, which …

Privacy-Preserving Feedback Loop Using Synthesized Contextual Exemplars, Tomek Rutowski, Paramesh Manickavelu, Paul Hsu, Saeed Mirza, Stevan Malesevic

Defensive Publications Series

A challenge for natural-language-to-SQL systems involves leveraging historical user context to improve query generation while mitigating privacy and security risks associated with storing raw user data. A method can address this through a privacy-preserving feedback loop. A system can programmatically identify successful query interactions, and then anonymize and synthesize the conversational history into an exemplar composed of a synthetic natural language intent and its corresponding successful structured query language query. These anonymized exemplars may be stored in a shared, decoupled repository. When a user submits a new query, relevant historical exemplars can be retrieved and injected as few-shot examples into …

Smart Contracts And Contractual Interpretation, Abhinav Ravi

Indian Journal of Law and Technology

This essay examines the challenges that smart contracts pose for contractual interpretation. While smart contracts are often viewed as unambiguous because they operate through deterministic computer code, disputes may nevertheless arise where the outcome produced by the code diverges from the parties’ understanding of their agreement. The essay argues that these disputes are not adequately addressed by treating code as a definitive expression of contractual intention or by adopting the ‘reasonable coder’ standard proposed by the United Kingdom (‘UK’) Law Commission. The reasonable coder standard is theoretically incoherent because it lacks alignment, generality, and reviewability and therefore cannot perform the …

System Design And Validation Of Radio Astronomy Phased Arrays, Rebecca Shiu Haymore

Theses and Dissertations

Modern radio astronomy instruments require a wide field of view and high sensitivity. To this effect, BYU and Cornell University have developed the Advanced L-band Phased Array Camera for Astronomy (ALPACA), a fully cryogenic 69 dual-pol dipole array that produces 80 beams on the sky with 305 MHz instantaneous bandwidth centered on 1500 MHz. Integration testing has demonstrated proper beamforming and calibration, and ALPACA has been commissioned as an all-sky monitor to search for bright transients. Commissioning testing for ALPACA measured an element system noise temperature of 24 K and a beamformed system noise temperature of 17 K, making ALPACA …

Stop Blaming My Users: Illumination Of The Technocentric Mythos Bias, Ervin H. Frenzel, Richard Lightcap

Journal of Cybersecurity Education, Research and Practice

 Abstract -This conceptual essay addresses the need for systemic and systematic transdisciplinary analytical techniques within cybersecurity and technical security. This conceptual essay is contingent upon recognition that cybersecurity is not simply technical in nature, it does not need an adversary, and more importantly it is based upon systems engineering and systems thinking.  The essay contributes a socio-technical attribution chain and field-specific ontology/taxonomy which distinguish user-triggered events from root causes, latent conditions, technical debt, validation failures, governance failures, and attribution bias before assigning responsibility to end users. It systematically defines an ontology inclusive of developer technical debt, organizational debt arising from …

Integrated Construction Risk Assessment Framework, Felix Delmonte

Mechanical and Civil Engineering Faculty Publications

An integrated risk assessment architecture for construction projects synthesizes data governance, BIM, Digital Twins, and hybrid analytics into a continuous feedback loop that links sensing, semantic modelling, probabilistic simulation, and organizational learning. The framework distinguishes aleatory from cognitive uncertainty and prescribes layered methods: Monte Carlo and Bayesian updating for measurable variability; fuzzy inference and consensus aggregation for linguistic and expert judgements; and graph-based discovery for dynamic cyber-physical topologies represented as time-varying graphs 𝐺𝑡. Governance primitives, aligned with ISO 19650, enforce provenance, interoperability, and staged readiness thresholds that prevent premature prescriptive outputs until model convergence criteria are met. BIM and GIS …

Biographex: Multi-Level Explainability In Graph Neural Networks For Trustworthy Biomedical Ai, Muhammad Talha Sajid, Ahmad Kamran Malik, Nafees Qamar, Hasnian Abudullah, Aleem Ahmad

Biological and Biomedical Sciences Department Faculty Journal Articles

In biomedical research and clinical practices, Graph Neural Networks (GNNs) are playing an increasingly important role and have been applied to the problems of disease pathway detection, gene–disease relation prediction, etc. They show great potential for biomedical predictions; however, there are interpretability issues when used on complex datasets like gene expression data. Current explainability methods such as GNNExplainer are designed to explain individual instances, not the whole network. The absence of transparency hinders trust and limits the clinical/biomedical implementation of GNNs. Additionally, more interpretable models like GNN-SubNet and XGDAG do not fulfill the expectation of a clear picture for the …

Escaping The Cyberstorm: A Gamified Social Engineering Training Program, Noah Mcclanahan, Fadi Abu-Amara, Ali Khattab, Travis Jett, Andre Jackson

Journal of Cybersecurity Education, Research and Practice

In this research work, we explored the effectiveness of gamification in improving cybersecurity awareness and training users on targeted social engineering attacks. Traditional cybersecurity training focuses on lectures and videos. These training methods may not actively engage employees, which reduces their knowledge retention and ability to recognize social engineering attacks. This lack of involvement is a concern, as social engineering continues to be one of the most prevalent attack methods faced by end-users. A gamified training program, Escaping the Cyberstorm, was developed using the Godot game engine to address key challenges in spreading cybersecurity awareness. The game includes real-life …

Ai-Guided Psychodrama Materials For Psychiatric Nursing: Feasibility Of Ai-Validated Synthetic Cases, Yen-Chung Ho, Chien Mei Sung

International Nursing Research Congress (INRC)

Background: Psychodrama is widely used in psychiatric–mental health nursing to help learners recognize and reorganize dysfunctional family-of-origin or role patterns, but faculty still lack standardized, reproducible, and ethically safe scripts (Giacomucci, 2021; Beauvais, Özbas, & Wheeler, 2019; Çataldas, Atkan, & Eminoğlu, 2024). Recent work on AI in nursing education and on privacy-preserving synthetic data suggests that high-fidelity, non–patient-derived materials can be generated if outputs are quality-checked (Lifshits & Rosenberg, 2024; Cucci, 2025; Qian et al., 2024; Mendes, Barbar, & Refaie, 2025).

Purpose: To test the feasibility of an AI workflow that generates a synthetic psychodrama case, converts it into multimodal …

Investigating Learning In Immersive Virtual Reality, Andrew Negrette

Master's Theses

Students often struggle with learning challenging subjects throughout their education. This also tends to lead to lower enjoyment and science self-efficacy for learning. Some subjects may be better represented in 3-dimensional spaces utilizing immersive virtual reality (IVR). Recently, IVR headsets have become more accessible and affordable and therefore are in wider use. The purpose of this study was to investigate whether differences in science selfefficacy, enjoyment, presence and knowledge retention exist between IVR and controls on an ocean acidification lesson. I predicted that participants taking the lesson in IVR would score higher compared to a laptop on all measures, due …
