We present ionizing photon production efficiencies (ξ_ion) for 63 z = 1.5–6.9 star-forming galaxies using precise nebular dust attenuation corrections from the JWST Assembly of Ultradeep Rest-optical Observations Revealing Astrophysics (AURORA) survey. A subset of objects within AURORA have individually determined nebular dust attenuation curves, which vary significantly in shape and normalization, resulting in reduced systematic uncertainty when constraining the total attenuation of Hα luminosity, and thus the intrinsic ionizing output within our sample. We find evidence for positive correlations between ξ_ion and redshift, equivalent width of [O iii] λ5007, and O32 = [O iii] λ5007/[O ii] …

Currently, occupational therapists in the NICU focus on observable infant occupations including oral feeding, holding, and social interaction. Occupational therapy can support families by promoting engagement in meaningful cooccupations, encouraging balanced routines and roles, providing caregiver education, and adapting tasks or environments to meet family needs.

Methodology: A literature review was conducted prior to arrival on site to understand the needs of parents in the NICU. After the arrival on …

Using Maximum Entropy (Maxent) Tool In Arcgis Pro For Species Distribution Modelling Of Pseudoscorpions In The Pacific Northwest, Elliot Toshihiro Cochran

Masters in GIS Practicum Reports

The use of Geographic Information Systems (GIS) to create Species Distribution Models (SDMs) is rising among many scientific disciplines. Many professionals who were not originally focused on GIS are increasingly becoming more invested in this technology. SDMs are widely used to estimate species’ potential geographic distributions and to evaluate the environmental factors that constrain their ranges. The presence-only maximum entropy (MaxEnt) algorithm implemented in the MaxEnt tool in ArcGIS Pro was used in this project to model habitat suitability for two species of pseudoscorpions, M. pacificus and an undescribed species, in Oregon and Washington. Presence points (of specimen sample locations) …

Development Of Thermal Joints For Conduction-Cooling Applications, J. Lewis, G. Ciovati

Mechanical & Aerospace Engineering Faculty Publications

In support of the development of conduction-cooled superconducting radiofrequency (SRF) niobium cavities for use in continuous-wave linear accelerators, an experimental study of thermal contact resistance was performed on bolted joints using high-purity niobium, aluminium, and copper along with Apiezon N grease and indium foil as interfacial materials. The geometry of each joint investigated aims at replicating the design adopted in conduction-cooled SRF cavities currently under development at Jefferson Lab. The materials' thermal conductivity and the joints' thermal resistance were measured in the temperature range of 3.5 - 10 K. The results showed that the low thermal contact resistance of 2-4 …

A Qualitative Multiple Case Study Exploring Shifts In Thinking Of Principals Through Initiatives To Foster Relational Leadership Conducive To Retaining Teachers In High-Minority, High-Poverty Public Schools, Rita Seay

Dissertations

Problem

The public education system is broken, and teacher shortages have reached a crisis, especially in some specialty fields in United States (Carrillo & Salhotra, 2022; Podolsky et al., 2016). Lately, the teacher workforce has been described as a “leaky bucket” (Podolsky et al., 2016, p. 1). Indeed, the problems are complex in poor socioeconomic communities with racial and ethnic groups of students because teachers struggle to make a difference and, in most cases, fail due to insurmountable situations that are beyond their scope of influence (Rondfeldt et al., 2013). Evidence published that students suffer immensely from a broken, segregated …

Handwriting Recognition In Vr, Dominique Mosley

EWU Masters Thesis Collection

Virtual Reality (VR) is slowly becoming more popular for more than just entertainment. VR can be found in educational, office, and even healthcare settings to help discover more intuitive ways to teach, collaborate, and treat patients. Outside of the virtual world, these environments typically rely on writing for communicating or note-taking. Currently, VR input forces users to rely on clunky on-screen keyboards which disrupts the user’s immersion and breaks the flow of natural interaction. This thesis explores the potential of VR as a learning platform by combining it with artificial intelligence (AI). It aims to develop a VR-enhanced handwriting practicing …

Assessing Forest Health And Small Mammals After A Limited Suppression Wildfire In Colville National Forest, Samantha J. Kennel

EWU Masters Thesis Collection

In the face of a wildfire crisis, there is a growing need to expand the pace and scale of forest treatments, including the strategic use of wildfire as a management tool. However, ecological outcomes remain uncertain in forests shaped by more than a century of fire suppression. The 2022 Thor Fire, a managed wildfire in the Colville National Forest, Washington, provides an opportunity to evaluate forest health in a relatively understudied system. Using a control–impact design, I established 100 monitoring plots in burned and adjacent unburned forests to assess how wildfire and fire severity influence forest structure, fuels, and tree …

Relationships Between Benthic Macroinvertebrate Communities And Environmental Conditions In Headwater Tributaries Of The Pend Oreille Lake Watershed, Idaho, Devlin Mee

EWU Masters Thesis Collection

Benthic macroinvertebrates are widely used indicators of stream condition, and their communities respond to thermal and land-use conditions in headwater streams. This study characterized macroinvertebrate biomass, community composition, and diversity across forested headwater tributaries of the Pend Oreille lake watershed in northern Idaho, and examined their relationships with summer temperature, land development, and road proximity. Samples from thirteen streams collected in 2024 were identified to genus, measured, and converted to estimated biomass using published length–mass regressions; ten streams had recovered temperature loggers. Because environmental variables were characterized once per stream, all analyses were conducted at the stream level.

Estimated total …

Dietary Ecology Of Waterfowl Nest Predators In The Prairie Pothole Region: Evaluating Resource Use From Species To Individual Using Stable Isotope Analysis, Grace Barthelmess

EWU Masters Thesis Collection

Nest predation is a primary factor influencing waterfowl productivity in the Prairie Pothole Region (PPR) of North America. Although this system is intensely managed and studied, research has largely focused on how predators affect waterfowl populations, with comparatively little attention to how predators actually rely on waterfowl as a resource. Understanding predator feeding ecology is therefore critical for informing effective management strategies and interpreting the complexity of predator-prey interactions on this landscape. My objective overall was to elucidate the feeding ecology of nine focal predator species commonly associated with waterfowl nest predation in the Aspen Parkland Ecoregion of the PPR: …

Standardized Sdoh Screening To Improve Obesity Management In Primary Care, Janessa Webster

Doctor of Nursing Practice (DNP) Scholarly Projects

Obesity is a complex chronic condition disproportionately affecting marginalized populations, with outcomes heavily influenced by Social Determinants of Health (SDoH). In primary care, a lack of standardized SDoH screening often leaves critical social barriers unrecognized, hindering lifestyle modification and weight management efforts. This quality improvement project evaluated implementing the standardized Core-5 SDoH screening tool in adult patients (BMI ≥ 30) during obesity management visits over eight weeks. Before implementation, we independently verified local community resources to confirm active capacity. The project increased the standardized screening completion rate from 0% to 100% (n = 77) among eligible encounters. Of the 77 …

The intervention incorporated self-monitoring of blood glucose (SMBG) review and provider feedback, medication adherence assessment, prescription review in the patient’s preferred language, diabetes self-management education and support reinforcement, nutrition counseling or dietitian referral, and follow-up planning. Thirty patients were consecutively enrolled. Following the implementation, medication adherence …

Robust Broadband Characterization Of Flexible Absorbers, Sheet Material, And Liquids Using A Coaxial Structure, Joseph Christopher Stecher

Masters Theses

Modern high-frequency measurement systems require reliable calibration and sample positioning to ensure measurement fidelity. This thesis presents three studies addressing practical limitations in broadband material parameter extraction and instrumentation.

The first study introduces a modified Nicolson–Ross–Weir (NRW) technique for flexible, compression-sensitive materials from 100 MHz to 18 GHz. Rigid 3D-printed spacers ensure precise sample positioning, and a T-matrix–based de-embedding procedure removes spacer effects. Validation using microstrip measurements and full-wave simulation confirms accurate permittivity extraction across compression levels.

The second study extends NRW to sheet materials enabling accurate material characterization. Independent validation using toroidal inductors with leakage correction and parallel-plate capacitors …

Assessment And Comparison Of Selected Carbon Ablation Models In Hypersonic Free-Flight And Arc-Jet Conditions, Andrew Steven Heider

Masters Theses

Accurate prediction of ablative thermal protection system (TPS) performance is critical for hypersonic vehicle design. However, numerical prediction of ablation remains challenging because results are influenced by complex physics and the choice of surface chemistry model and assumptions made in material response calculations. The objective of this work is to evaluate several carbon ablation models and their implementation within modern computational fluid dynamics (CFD) codes. Numerical simulations were performed using NASA’s LAURA flow solver and the commercial CFD code ANSYS Fluent, which coupled Navier-Stokes with surface chemistry models describing carbon oxidation, nitridation, and sublimation reactions. Several reaction sets were considered, …

Analyzing Sleep Architecture And Brain State Transitions Via Hidden Markov Models On Fmri Data, Brileigh Jay Cates

Masters Theses

Sleep is associated with systematic changes in brain activity and functional connectivity observable in functional magnetic resonance imagining (fMRI) signals. Because subjects often fall asleep during resting-state experiments, the absence of vigilance monitoring can confound the interpretation of resting-state dynamics. Although electroencephalography (EEG) is the gold standard for sleep staging, simultaneous EEG-fMRI acquisition is not always feasible.

This study investigates whether sleep stages can be inferred directly from fMRI using a probabilistic latent-state framework. Hidden Markov Models (HMMs) are applied to blood-oxygen-level-dependent (BOLD) time series to identify latent brain states and their temporal transitions. Inferred states are aligned with EEG-derived …

Autonomous Navigation Development And On-Ground Validation For Satellite Rendezvous And Proximity Operations, Logan Banker

Masters Theses

Spacecraft rendezvous and docking are critical mission phases for various applications of spaceflight, including active debris removal (ADR) and in-orbit servicing, assembly, and manufacturing (ISAM). While previous missions utilized humans to perform rendezvous and docking, this style of mission greatly increases safety risks and cannot be implemented on a large scale. Autonomous servicing satellites provide a path towards scalable rendezvous and proximity operations (RPO) because these autonomous agents do not require human intervention. This work presents a lightweight convolutional neural network (CNN) for the navigation system of an agent which analyzes monocular images and predicts the target's position and orientation …

Examination Of Laser Microwelding As A Technique For The Repair Of Steel Castings, Allan John Woldow

Masters Theses

"Metal castings have long been plagued with minor defects caused by various process and design conditions. Commonly, minor defects are not seen until after machining operations have been completed, and by the time they are identified, they cannot be salvaged in a manner that is structurally sound and does not have other detrimental effects on the product. Detrimental effects may include warping from high heat input in traditional welding, warping from reheat treatment, oxidation of machined surfaces, microstructural anomalies, and reduced mechanical properties. Micro laser welding has the potential to provide a solution to these issues by providing a low …

Unlearning Tension: How The Alexander Technique Enhances Body Awareness In Performance, Clayton Stoker

Senior Honors Theses and Projects

The Alexander Technique assists in identifying, releasing, and redirecting patterns of tension to create new direction. Built on tenets of awareness, inhibition, and direction, this technique can be applied to everyday activities. The Alexander Technique brings awareness to recognize inefficient and unhealthy habits, giving the body a new direction. While working on my music degree at Eastern Michigan University, I initially focused on playing accurately rather than the tension in my playing. Through guided exercises and self-observation, I became aware of inefficient movement, which piqued my curiosity. This thesis draws on tenets of the Alexander Technique that demonstrate how conscious …

Examination Of Awareness And Frequency Of Behavioral Masking/Camouflaging Based On Life Experiences, Elizabeth M. Smith

Senior Honors Theses and Projects

Camouflaging behaviors are typically employed by individuals with autism spectrum disorder (ASD) to appear more in line with societal norms and avoid social ostracization. This study examined the connections between camouflaging and theatre experience, mental health diagnostic status, and levels of self-monitoring. In the study, participants completed a brief, 30- minute survey online examining camouflaging, autistic traits, self-monitoring, and life experiences across individuals of different age ranges. All participants were 18 years of age or older, completed a consent form, and received a debriefing. All responses were completely anonymous. The results showed significantly higher levels of camouflaging behaviors in participants …

Zero Tolerance Discipline In American Schools: Racial Injustice In The Age Of Youth Disposability, Trinity J. Perkins

Senior Honors Theses and Projects

This study critically examines how neoliberal social controls and school-based criminalization efforts emerged in response to a series of moral panics surrounding perceived increases in school violence and mass shootings. Largely, this response manifested in the form of rigid zerotolerance disciplinary policies focused on deterrence and retribution. However, research reveals the application of these policies produce racial and income-based disparities in how school discipline is administered, which contributes to the school-to-prison pipeline (i.e., a pathway for youth to be funneled out of education and into incarceration). As such, it is believed that racial threat dynamics may be contributing to the …

The Effects Of Surf Film Viewing As A Dialectical Behavior Therapy-Aligned Intervention For Trauma-Related Symptoms, Ryan Papero

Senior Honors Theses and Projects

This study examined whether viewing a surf film aligned with Dialectical Behavior Therapy (DBT) principles would reduce emotion dysregulation among trauma-exposed adults. Participants (N = 14) with self-reported childhood trauma were randomly assigned to view either The Endless Summer or a neutral industrial documentary. Emotion regulation was assessed using pre- and post-intervention Difficulties in Emotion Regulation Scale (DERS) scores. An independent samples t-test comparing change scores indicated that the control group demonstrated a greater mean reduction in DERS scores (M = 6.13, SD = 5.22) than the surf group (M = 2.50, SD = 3.08); however, this difference was not …

Breaking The Glass: Jewish Identity Through A Sociological Lens, Shayla Mostyn

Senior Honors Theses and Projects

This project uses Charles H. Cooley’s theory “The Looking-Glass Self” to magnify the depth of Jewish identity. As a Jewish student, I have firsthand experience in experiencing society normalize acts of antisemitism and it having a negative impact on my Jewish identity. Within my research, 200 Jewish college students from around the world were provided with a platform to anonymously reflect and report on what being Jewish means to them and how their social surroundings impact their Jewish identity. This concept tells that one’s identity or concept of identity is based on how others see them or how they believe …

Giddy Character Rig, Arden Jean Millhouse-Lewis

Senior Honors Theses and Projects

This project was an in-depth investigation into creating a production-ready rig using the widely used industry-standard software, Autodesk Maya. Using a character I designed, modeled, and shaded, I explored the workflow of bringing it to life through the technical lens of rigging, then tested its functionality in animation, troubleshooting, and further refining the overall rig as I went. I revised the prior model’s topology to create optimal edge flow for deformations before I went on to place it in the skeletal hierarchy, accounting for not only the bones of the character but also secondary bones in the clothing, hair, and …

The Impact Of Michigan's Public Act 308 On Foster Care Outcomes: A Synthetic Control Analysis, Maruis D. Martello

Senior Honors Theses and Projects

This paper evaluates the impact of Michigan’s 2014 Public Act 308 on foster care adoption outcomes. By converting traditional adoption subsidies into dynamic, redeterminable contracts, the policy aimed to reduce the financial uncertainty associated with adopting children with latent or evolving special needs. Using data from the Adoption and Foster Care Analysis and Reporting System (AFCARS) from 2000 to 2022, we implement a generalized synthetic control method to account for unobserved time-varying heterogeneity. We find that the policy had no statistically significant impact on the aggregate adoption rate. However, it generated significant gains within targeted subpopulations, increasing the probability of …

Investigating The Effects Of Atg3 On Autophagosome Size And Number, Keeran R. Senthil Kumar

Senior Honors Theses and Projects

Macroautophagy, or autophagy, is a highly conserved catabolic process in all eukaryotes which allows for the degradation of large cytosolic contents. It occurs in two forms: bulk autophagy, which is induced by nutrient deprivation and targets nonspecific cargo, and selective autophagy, which is induced by cellular stress and sequesters specific substrates. The process of autophagosome formation is carried out by a group of Atg (autophagy-related) proteins, one of which is Atg3. Atg3 functions as an E2-like enzyme by conjugating Atg8 — a ubiquitin-like protein — to phosphatidylethanolamine (PE), a step required for autophagosome membrane formation. This lipidation process is catalyzed …

Oligarchy And Democratic Decline: A Platonic Framework For Analyzing The Contemporary American Political System, Jonah Huskey-Wright

Senior Honors Theses and Projects

This paper explores the idea that there is a meaningful philosophical connection between Plato’s account of oligarchy and the development of the modern American political order. Rather than approaching American politics only through constitutional design, electoral procedures, or institutional mechanics, the paper argues that political systems must also be understood as reflections of the values and motivations of the people who inhabit them. Drawing on Plato’s framework that links the ordering of the human soul to the ordering of political regimes, the project examines how the priorities a society places on certain goods—particularly wealth, economic achievement, and material success—can shape …
