Community Resilience Drives Change, Claudia Rose Dilima Jan 2026

Community Resilience Drives Change, Claudia Rose Dilima

Graduate Theses, Dissertations, and Problem Reports (ETD)

The opioid crisis has impacted many Americans. From 1999 to 2023, approximately 800,000 people have died due to opioid overdose (CDC, 2025). What began as overprescription of painkillers has evolved into a complex social health issue that is now worsened by stronger synthetic drugs like fentanyl. Fentanyl and fentanyl analogs (synthetic opioids that are very similar chemically to fentanyl) are often found in illegal drug supplies and in counterfeit pills (CDC, 2025). Thus, individuals who might have been initially overprescribed painkillers might now be pushed toward illegally produced drugs that are significantly more potent than what they were originally prescribed. …


Enhancing Chime Data Integrity: Utilizing An Ancillary Antenna To Detect And Mask Radio Frequency Interference, John W. Metzger Jan 2026

Enhancing Chime Data Integrity: Utilizing An Ancillary Antenna To Detect And Mask Radio Frequency Interference, John W. Metzger

Graduate Theses, Dissertations, and Problem Reports (ETD)

The Canadian Hydrogen Intensity Mapping Experiment (CHIME) is a radio telescope array designed to map Baryon Acoustic Oscillations (BAO) and detect Fast Radio Bursts (FRBs) within the 400-800 MHz frequency range. However, man-made Radio Frequency Interference (RFI), such as television broadcasts and cellular signals, significantly degrade data integrity and mask weak astronomical signals. This thesis details the design, simulation, and implementation of a slotted waveguide antenna at the Green Bank Outrigger (GBO) to detect and mask RFI. Utilizing cross-correlation, the system identifies similarities between the telescope and the horizon- pointing antenna to isolate interference. Mathematical models were used to determine …

Machine Learning-Based Prediction Of Heavy-Duty Diesel Engine Emissions And Comparative Analysis Against Statistical Models, Abdullah Ahmad Khan Jan 2026

Machine Learning-Based Prediction Of Heavy-Duty Diesel Engine Emissions And Comparative Analysis Against Statistical Models, Abdullah Ahmad Khan

Graduate Theses, Dissertations, and Problem Reports (ETD)

The increasing stringency of emissions regulations for heavy-duty (HD) diesel engines necessitates the development of accurate, efficient, and general predictive models for engine-out emissions under steady-state operating conditions. Traditional statistical approaches, while computationally efficient, often fail to capture the inherent nonlinear relationships between the engine operating parameters and emissions formation. In contrast, machine learning (ML) techniques offer a promising alternative by learning the complex patterns directly from experimental data. The present thesis summarizes a comprehensive study on the prediction of steady-state, HD diesel engine emissions using ML models, along with a comparative analysis against conventional statistical modeling approaches.

A high-quality …


A Digital Calibration Source For 21 Cm Cosmology Telescopes, Kalyani Balkrishna Bhopi Jan 2026

A Digital Calibration Source For 21 Cm Cosmology Telescopes, Kalyani Balkrishna Bhopi

Graduate Theses, Dissertations, and Problem Reports (ETD)

Precise calibration of radio telescope beams and gains is a central requirement for 21 cm intensity mapping experiments, which aim to measure large scale cosmological structure through the redshifted emission line of neutral hydrogen. Bright astrophysical foregrounds dominate the sky at these frequencies, and separating them from the cosmological signal demands precise control over instrumental systematics, particularly the telescope beam and its frequency-dependent response. Existing aerial calibration sources are incoherent broadband emitters, detectable only as total power. They provide no direct phase information and suffer from poor sensitivity in low signal-to-noise regimes.

We present the Precision Emitter for 21cm Array …


Ai-Driven Prediction And Reconstruction Of Missing Cased-Hole Logs For Improved Well System Understanding, Samuel Avilez Martinez Jan 2026

Ai-Driven Prediction And Reconstruction Of Missing Cased-Hole Logs For Improved Well System Understanding, Samuel Avilez Martinez

Graduate Theses, Dissertations, and Problem Reports (ETD)

Well logging is a fundamental technique in formation evaluation providing continuous, real-time measurements of geological and petrophysical properties within a well. Through the systematic analysis of well logs, engineers and geoscientists can accurately determine critical formation characteristics, including porosity, permeability, lithology, and fluid composition. Well logging is fundamental for making informed decisions and reducing uncertainties in the exploration and development of oil and gas reservoirs.

Despite its significance, the acquisition of reliable well log data in oil and gas wells is often compromised by various operational, mechanical, and formation-related challenges, as well as pressure, fluid, and equipment constraints. In high-risk …


Simulation Optimization Of Intermodal Freight Transportation Under Disruptions, Israt Humayra Jan 2026

Simulation Optimization Of Intermodal Freight Transportation Under Disruptions, Israt Humayra

Graduate Theses, Dissertations, and Problem Reports (ETD)

Rapid growth in freight transportation in modern supply chains has led to increased operational costs, congestion, and severe environmental impacts, especially greenhouse gas emissions. Combining different modes, such as highway, railway, and waterway, intermodal transportation could thus offer considerable benefit to improve efficiency, sustainability, and resilience. However, most existing planning approaches rely on simplified assumptions, fixed schedules, and average cost estimates, making them less relevant to dealing with real-world uncertainties and disruptions. This study develops a simulation-optimization framework for intermodal freight transportation under disruption. We develop a mixed-integer programming model to represent an intermodal logistics planning framework on a multi-layered …


Do You Walk On By? The Effects Of Donor Fatigue On Willingness To Donate, Shawn Michael Henry Jan 2026

Do You Walk On By? The Effects Of Donor Fatigue On Willingness To Donate, Shawn Michael Henry

Graduate Theses, Dissertations, and Problem Reports (ETD)

Donation solicitation literature validates the successful usage of various solicitation tactics that lead to achieving set donation goals for their associated cause. Yet, while the financial success of “checkout charity” is well-documented, a significant gap remains regarding the impact of high-frequency solicitations on long-term consumer-brand relationship. This research addresses this gap. Over the span of three surveys, this study finds that donation request frequency overall erodes donation likelihood through donor fatigue when donation frequency changes (occasional vs. always). However, this relationship is moderated by the perceived consumer base, with a larger perceived consumer base exacerbating the “diffusion of responsibility.” Further, …

School of Psychology

Early learning takes place within complex, multimodal environments where curiosity plays a critical role in guiding exploratory behaviors and supporting cognitive development. While trait curiosity shapes children’s early learning experiences, state curiosity is context-dependent fostering early learning, in-part, through information seeking behaviors. Here, we explore whether state-induced curiosity can influence exploratory behaviors and facilitate word learningwithin a multimodal search task that mirrors real-world learning environments.Children (2.5- to 4-year-olds) will be introduced to novel objects and labels via a storybook. After exposure to each novel object, participants will locate the target object (i.e., a sticker depicting the novel object), hidden within …

Three Essays In Cpi Bias And Health Economics, Auderta Amoako-Nuamah Jan 2026

Three Essays In Cpi Bias And Health Economics, Auderta Amoako-Nuamah

Graduate Theses, Dissertations, and Problem Reports (ETD)

The first essay estimates bias in the Consumer Price Index (CPI) for elderly individuals in the United States using Engel curve methodology and household-level data from the Panel Study of Income Dynamics (1999–2023). The analysis focuses on how well the CPI reflects changes in the cost of living for older Americans, with particular attention to differences by gender and marital status. Results show that from 1999–2011, the CPI overstated the increase in the cost of living for both elderly and non-elderly households. In contrast, from 1999–2023, the CPI understated cost increases, with the bias generally larger for non-elderly households. Within …

His Cues, Her Cues: Teaching Presence, Gender, And Relational Impressions In Online Learning, Kyle R. Vareberg, Ryan Goke, Ian Berry, Maranda Goke, Stephanie Kelly Jan 2026

His Cues, Her Cues: Teaching Presence, Gender, And Relational Impressions In Online Learning, Kyle R. Vareberg, Ryan Goke, Ian Berry, Maranda Goke, Stephanie Kelly

Iowa Journal of Communication

Online courses are increasingly common and taken more frequently by students, yet students' perceptions of them may portray instructors as invisible and uninvolved. Drawing on social information processing theory, we argue that cues intended to signal course design are also interpreted relationally. Teaching presence, the work instructors do to be “present” in the online environment, is not merely instructional structure: it is relational communication embedded in course design. This study explored whether teaching presence and students' perceptions of immediacy and credibility are related, and whether those relationships differ by student gender. Using a cross-sectional survey, we divided our sample into …

Extracting accurate results from neutrino oscillation and cross section experiments requires accurate simulation of the neutrino-nucleus interaction. The rescattering of outgoing hadrons (final state interactions) by the rest of the nucleus is an important component of these interactions. We present a new measurement of proton transparency (defined as the fraction of outgoing protons that emerge without significant rescattering) using electron-nucleus scattering data recorded by the CLAS detector at Jefferson Laboratory on helium, carbon, and iron targets. This analysis uses a new data-driven method to extract the transparency. It defines transparency as the ratio of electron-scattering events with a detected proton …


Studying Electroweak Few-Body Observables In Chiral Effective Field Theory, Alex Gnech Jan 2026

Studying Electroweak Few-Body Observables In Chiral Effective Field Theory, Alex Gnech

Physics Faculty Publications

The use of nuclei to study electroweak probes is becoming increasingly relevant experimentally. The success of dark matter and neutrino experiments strongly depends on the ability to control nuclear effects in order to extract the fundamental parameters associated with external probes. Therefore, reliable theoretical calculations of nuclear structure and reactions, with well-controlled errors, are crucial for the success of experimental efforts. Currently, chiral effective field theory (χEFT) coupled with {\it ab-initio} methods represents one of the best approaches that fulfills these requirements. To use this approach as a tool for studying fundamental physics, it is essential to validate it against …

The polarization of Λ hyperons is preserved in the angular distribution of their decay products. This property allows one to study the spin structure of the Λ. In semi-inclusive deep inelastic scattering where a high energy lepton interacts with a nucleon target and one or more hadrons and the scattered lepton are detected in the final state, the probability for a struck quark to impart the polarization of the lepton to the Λ may be measured. In particular, in electron-proton scattering this quantity may be related to the longitudinal light quark polarization of the Λ. Currently, limited experimental data cannot …


Likelihood-Based Inference For Random Networks With Changepoints, Daniel Cirkovic, Tiandong Wang, Xianyang Zhang Jan 2026

Likelihood-Based Inference For Random Networks With Changepoints, Daniel Cirkovic, Tiandong Wang, Xianyang Zhang

Mathematical and Statistical Science Faculty Research and Publications

Generative, temporal network models play an important role in analyzing the dependence structure and evolution patterns of complex networks. Due to the complicated nature of real network data, it is often naive to assume that the underlying data-generative mechanism itself is invariant with time. Such observation leads to the study of changepoints or sudden shifts in the distributional structure of the evolving network. In this paper, we propose a likelihood-based methodology to detect changepoints in undirected, affine preferential attachment networks where, upon introduction, a new node selects one old to attach to with probability proportional to its degree. In particular, …


Ambulatory Monitoring Of Biomarkers For Enhanced Recovery, Lucas Abrahamian, Gurman Dhami Jan 2026

Ambulatory Monitoring Of Biomarkers For Enhanced Recovery, Lucas Abrahamian, Gurman Dhami

Bioengineering Senior Theses

Oxidative stress, an imbalance of reactive oxygen species and antioxidants, serves as both a marker and progressor of several chronic and degenerative diseases. These conditions create a major global health burden, accounting for significant cost and deaths. The prevalence of oxidative stress–driven diseases highlights the need for improved strategies to detect the imbalance before irreversible damage occurs. However, despite its major role in disease progression, oxidative stress is typically assessed using static, invasive, or laboratory methods. These approaches are poorly suited for continuous monitoring and fail to serve high-risk groups, such as patients with a family history of disease or …


Fgf19 As A Colorectal Cancer Serum Biomarker And Fgfr4 As A Mediator Of Anti-Her2 Resistance In Breast Cancer, Jordan Beardsley Jan 2026

Fgf19 As A Colorectal Cancer Serum Biomarker And Fgfr4 As A Mediator Of Anti-Her2 Resistance In Breast Cancer, Jordan Beardsley

Graduate Studies Theses and Dissertations 2026

The fibroblast growth factor 19 (FGF19)-fibroblast growth factor receptor 4 (FGFR4) signaling pathway regulates hepatic metabolism, bile acid (BA) synthesis, and hepatocyte proliferation. This signaling axis also is implicated in promoting tumor progression, therapeutic resistance, and metastasis in certain cancers.

In colorectal cancer (CRC) there is a critical need for non-invasive biomarkers for disease detection and monitoring. We identified FGF19 as a candidate CRC serum marker through meta-transcriptomics and found FGF19 to be expressed and secreted by CRC cell lines. Tumor-derived FGF19 was detectable in mouse serum at levels correlating with tumor volume in a subcutaneous xenograft model. RNA sequencing …


Investigating The Impact Of School Leaders’ Leadership Style And Teachers’ Intrinsic Motivation For Improved Science Instruction In Elementary Schools, Leila M. Greene Jan 2026

Investigating The Impact Of School Leaders’ Leadership Style And Teachers’ Intrinsic Motivation For Improved Science Instruction In Elementary Schools, Leila M. Greene

Graduate Studies Theses and Dissertations 2026

A report by the National Academies of Sciences, Engineering, and Medicine, determined that 69% of U.S. elementary teachers are not prepared to teach science, especially in the areas of earth/space and physical sciences. As a result, some elementary teachers avoid teaching science. School administrators play a key role in providing a supportive environment to inspire and motivate elementary science teachers. For this reason, the study utilized the Self-Determination Theory (SDT), to examine three types of school leadership styles (Transformational, Transactional, and Laissez-Faire) and how they impact the intrinsic motivation for elementary science teachers in three areas including autonomy, competency, and …


Black Hole Spectroscopy And Tests Of General Relativity With Gw250114, Jaclyn (Jax) Sanders Jan 2026

Black Hole Spectroscopy And Tests Of General Relativity With Gw250114, Jaclyn (Jax) Sanders

Physics Faculty Research and Publications

The binary black hole signal GW250114, the loudest gravitational wave detected to date, offers a unique opportunity to test Einstein’s general relativity (GR) in the high-velocity, strong-gravity regime and probe whether the remnant conforms to the Kerr metric. Upon perturbation, black holes emit a spectrum of damped sinusoids with specific, complex frequencies. Our analysis of the postmerger signal shows that at least two quasinormal modes are required to explain the data, with the most damped remaining statistically significant for about one cycle. We probe the remnant’s Kerr nature by constraining the spectroscopic pattern of the dominant quadrupolar (ℓ=m=2) …

This collection is a digital project of dedicated teacher-scholars who met in the summer of 2025 as part of the University of Northern Iowa’s graduate program in Teaching English in the Secondary Schools (TESS). Using the theoretical lens of multiliteracies, developed by the New London Group in the 1990s, students examined the impacts of several electronic and digital technologies on their students and their teaching, especially Artificial Intelligence, or A.I. Through fiction, nonfiction, and discussion, students considered the changes, the challenges, and the opportunities these technologies held. Most importantly, they investigated what these developments meant for their teaching, their districts, …

Hypertension is a complicated, chronic condition that affects individuals worldwide. The prevalence of this condition has increased nearly 48% in the last decade in America. This project served to determine if participants in a targeted area/community would show increased knowledge and awareness of hypertension after implementation of educational sessions. A post-session survey was provided to determine if the educational sessions were effective. Data was collected and analyzed that showed an increase in awareness and knowledge regarding the prevalence of hypertension, diet modification, lifestyle, and compliance.

Doctor of Nursing Practice Projects

Vaping in teens has become an increasing public health issue related to the growth in the number of teens who are using vapes. Many teens are not aware of the potential associated risk of using vapes, as they perceive them to be a safer alternative to smoking cigarettes. The purpose of this project was to increase the middle school teens’ knowledge of the potential health risks associated with vaping through an educational awareness session. This project was implemented in the middle school setting, targeting students aged 12-14 years. The students who participated completed anonymous pre- and post- questionnaires that evaluated …
