The Power To Commission: Exploring The Evaluation Capacity And The Transformative Role Of Evaluation Commissioners In The International Development Sector, Ann Marie Castleman

CGU Theses & Dissertations

Evaluation commissioners play a central role in evaluation practice by generating demand for evaluation through issuing calls for evaluation services and managing evaluation contracts (Lemire, Nielsen et al., 2018; Nielsen et al., 2018b), particularly in the international development sector. Yet few competency sets specify the knowledge and skills needed to conduct this work. Even less is known about the evaluation marketplace in the international development sector and the contract mechanisms used to procure evaluation services.

This research explored the capacity to commission evaluation among international nongovernmental organization (INGO) evaluation commissioners, including individual competencies and practices for commissioning an evaluation, factors …

Declarative Design For Spatial Analysis Models, Yassine Elouri

CGU Theses & Dissertations

Geographic Information Systems (GIS) have become indispensable tools in addressing complex spatial challenges across diverse domains, including urban planning, environmental conservation, and climate change. However, the technical expertise required to use GIS effectively, particularly proficiency in general-purpose programming languages (GPLs), remains a significant barrier to broader adoption. Domain-Specific Languages (DSLs) have proven to lower this barrier by offering tailored abstractions that simplify problem-solving in specific domains. Despite their potential, the GIS domain lacks a formal DSL framework that bridges the gap between the design of spatial analysis models and their practical implementation. This research addresses this gap by proposing Gaia, …

Market Implied Risk-Free Rates: An Analysis Of The Put-Call Parity Implied Rate, Silviu Velovici

CGU Theses & Dissertations

This study investigates the interest rate implied by put-call parity as an alternative, market-based proxy for the risk-free rate. Studying the implied risk-free rate from option prices is important because it provides insights into how market participants collectively perceive short-term financing conditions, independent of official Treasury-Bill yields. Since Treasury securities and the LIBOR are conventionally used as proxies for the risk-free rate, any persistent discrepancy between the put-call parity implied rate and the Treasury-Bill rate, or the put-call parity implied spread, can be interpreted as a signal of market frictions, investor behavior anomalies, sentiment-driven pricing dynamics, or information asymmetries.

Traditional And Non-Traditional Behavioral Tests Demonstrate The Attenuation Of Cognitive Deficits By Therapeutic Hypothermia In A Rat Model Of Neonatal Hypoxic-Ischemic Encephalopathy, Angela Saadat, Cortney Kaszowski, Haree Pallera, Frank Lattanzio, Richard A. Britten, Asna Sulaiman, Stephanie Newman, Alireza Hosseini, Tushar Shah

Department of Pediatrics Faculty Publications

Introduction: Neonatal hypoxic-ischemic encephalopathy (HIE) is neurological disease caused by the deprivation of oxygen and blood flow to the brain during the developmentally-critical perinatal period. Therapeutic hypothermia (TH) is the standard of care treatment for HIE, though cognitive deficits can persistent throughout life despite treatment. The nature of these deficits, and the impacts of TH and sex are not well understood, and this presents a key barrier in the development of novel therapeutics.

Methods: The goal of this study was to enhance the characterization and measurement of cognitive outcomes with tasks that measure spontaneous behaviors in a rodent models of …

A Bibliometric Analysis Of Ai-Driven Healthcare Literature Containing Kos Keywords: Trends, Themes, And Gaps, Julaine Clunis, Eric Asare

STEMPS Faculty Publications

As artificial intelligence (AI) becomes increasingly embedded in healthcare applications, concerns have emerged around the trustworthiness, interpretability, and context-awareness of these systems. Knowledge Organization Systems (KOS) hold considerable potential to address these challenges by supporting semantic standardization, explainability, and domain alignment. This study presents a bibliometric analysis of scholarly publications referencing both AI and healthcare concepts to examine how KOS are positioned within this evolving discourse. The findings indicate that while early literature frequently and explicitly referenced KOS—such as ontologies, controlled vocabularies, and classification systems—their visibility has declined relative to newer paradigms such as machine learning and large language models. …

Patterns Of Exclusive, Dual And Poly Tobacco Products Use Among Cancer Survivors In The United States, Ateeqa Ijaz, Miranda E. Gehris, Paul T. Harrell, Aditya Chakraborty, Rime Jebai, Wei Li, Olatokunbo Osibogun, Seyedeh Yasaman Alemohammad, Ziyad Ben Taleb, Ebbie Kalan

Department of Pediatrics Faculty Publications

Purpose

Identifying tobacco products use (TPU) patterns among cancer survivors (CSs) is critical to optimize survivorship care. This study examines exclusive cigarette/e-cigarette, dual (two tobacco-products) and poly (≥ 3 tobacco-products) use among CSs (vs. no cancer history) and its sub-types: smoking-related-cancers (SRCs) vs. non-smoking-related cancers (NSRCs) while also exploring socio-demographic factors.

Methods

The study analyzed 86,551 adults from the 2021–2023 National Health Interview Survey, including 10,846 (9.7%) CSs. Participants were categorized and analyzed based on their CSs status and TPU patterns. Weighted logistic regression models assessed the relationship between TPU and CSs status while adjusting for socio-demographic characteristics.

Comprehensive Benchmarking Of Several Machine Learning And Bayesian Models For Early-Stage Diabetes Risk Prediction: A Large-Scale Comparative Study, Md. Iqbal Hossain, Najila Alam Porno

Mathematics & Statistics Faculty Publications

Diabetes remains a critical global health challenge, with early detection is crucial for effective management. This study presents a comprehensive benchmarking analysis of 14 diverse machine learning and Bayesian models for early-stage diabetes risk prediction using clinical data [2] from Sylhet, Bangladesh. This research evaluated traditional methods (Logistic Regression, Decision Trees), ensemble techniques (Random Forest, XGBoost, LightGBM), Bayesian approaches (BART, Bayesian Logistic Regression), and advanced neural architectures (Deep Belief Networks) using both 70-30 train-test splits and 10-fold cross-validation. The results demonstrate that ensemble methods consistently outperformed other approaches, with Random Forest(RF) achieving the highest cross-validated AUC (0.9951) and accuracy (0.9699). …

Optimal decision-making requires consideration of internal and external contexts. Biased decision-making is a transdiagnostic symptom of neuropsychiatric disorders. We created a computational model demonstrating how the striosome compartment of the striatum constructs a context-dependent mathematical space for decision-making computations, and how the matrix compartment uses this space to define action value. The model explains multiple experimental results and unifies other theories like reward prediction error, roles of the direct versus indirect pathways, and roles of the striosome versus matrix, under one framework. We also found, through new analyses, that striosome and matrix neurons increase their synchrony during difficult tasks, caused …

The Return Of War In International Politics, Chick Edmond, Nkenglefack Dessailly Forku

Political Science & Geography Faculty Publications

This article examines the resurgence of war in international politics after the Cold War. It contends that interstate wars have declined after 1990 and there was high optimism for stability and a cooperative international order, but contemporary conflicts have evolved into complex intrastate and asymmetric confrontations involving non-state actors, ethnic and religious divisions, resource competition, and geopolitical rivalries. The paper uses a constructivist approach and secondary qualitative data to identify and explore key drivers of this trend such as the rise of terrorist and insurgent groups, the politicization of identity, disputes over scarce resources, erosion of international norms, and intensifying …

Norfolk Core Redevelopments And Population Disruption Dispersal, Sumner Darling

Institute for the Humanities Master's Papers, Projects, and Capstones

This project is an analysis of the racial impacts of the redevelopment of the downtown area of Norfolk, Virginia in the period of 1939-1959. The overall goal is to understand the ethnic and racial impacts of redevelopment and how populations were treated differently during the two styles of redevelopment that were employed in the city. The existing research on this topic tends to focus on the segregation of the education system in the city over the community population segregation. This makes it difficult to find sources that show the impacts of other factors like redevelopment of minority communities. Through research …

Codec-M: The Multi-Lingual Manosphere Subcorpus Of The Corpus Of Digital Extremism And Conspiracies, Rachel Mccullough, Daniel Drylie, Mindl Barta, Cass Dykeman, Daniel Smith

English Faculty Publications

In 2023, the U.S. Surgeon General warned the public of the current “loneliness epidemic” and its potential consequences on physical and mental health. One possible consequence of this epidemic is the growth of a movement defined by loneliness and isolation: the incel (“involuntary celibate”) movement. This warning presents a worrying glimpse at the future, as the incel movement, along with other parts of the manosphere, is one that espouses violently misogynist rhetoric which is intrinsically linked to right-wing extremism. While linguistic studies have been conducted on the speech of incels and other constituent movements of the manosphere, few of these …

Hierarchies Of Violence, Victimhood, And Remedy In The Pursuit Of Women's Rights After War, Marie Berry, Milli Lake, Sinduja Raja, Soraya Zarook

English Faculty Publications

Recent postwar recovery efforts have paved the way for reforms that advance women's participation in politics, inclusion in the economy, and access to justice. In this article, we show how a singular emphasis on gender reforms after war that are inattentive to other societal cleavages can leave various forms of marginalization in the shadows. Subnational interviews on the reverberations of gender reforms in five postwar countries expose three hierarchies that structure access to rights for war-affected communities. We reveal which violence is privileged, whose violence is privileged, and which responses are privileged from the perspectives of differently situated war-affected women, …

"They Just Don't Have The "Doctor" In Front Of Their Name:" Dimensions Of Trust In Physician Assistants, Staci Defibaugh, Leah Onosato

English Faculty Publications

Physician assistants play a major role in healthcare delivery in the United States, yet what we know about how patients perceive the care they receive from PAs is limited. Prior research on patients’ impressions of PAs has focused primarily on survey data, limiting the scope of what we can learn about patient impressions to predetermined, quantifiable categories, and has focused on post-visit impressions of a single encounter. In an attempt to better understand patient impressions, we conducted open-ended, semi-structured interviews with 30 participants prior to their medical visit, focusing on general impressions of PAs. Through an analytic process of reflexive …

Toward A Decolonial Digitality: On Seb Franklin's The Digitally Disposed, Travis Alexander

English Faculty Publications

[Introduction] If the long hot summer of 2020 marked a season of racial reckoning, it was also—now visible in retrospect—a moment for processing with the relation between digital technologies and power. 8:46 after all names not only an event, a murder, but the title of a short digital film. A film, moreover, that has found decisively counterposed audiences in its ongoing afterlives. A forensics of police violence, on the one hand, 8:46 also avails, in the shadier corners of the dark web, the pleasures of a snuff film. In this way, 8:46 is emblematic of a broader, and, perhaps, terminal …

Analysis Of Aerosols In The Asian Monsoon Anticyclone As Observed By The Atmospheric Chemistry Experiment, M. Lecours, R. Dodangodage, C. D. Boone, P. F. Bernath

Chemistry & Biochemistry Faculty Publications

During the Asian summer monsoon season, pollutants from the lower troposphere are transported through deep convection to the upper troposphere and lower stratosphere. Surface pollutants such as CO are transported upward and trapped in the anticyclone during this unique atmospheric phenomenon. Associated with the anticyclone is a layer of enhanced aerosols located near the tropopause often referred to as the Asian tropopause aerosol layer (ATAL). The chemical and physical properties of aerosols in the ATAL are not yet fully understood as direct observations of the aerosols are limited. The Atmospheric Chemistry Experiment (ACE) is a satellite mission that provides high-resolution …

[Introduction]At the playground, my mother hid from me, I couldn’t find her, and I called her name a thousand times.

And when she reappeared, I ran to her, and she ran to me, and I clenched her neck, and I put my hands on her face, and I said, Where were you? Where were you? and she said, I’m so glad you found me. And we hugged, and she smiled as she cradled me, and I howled, like a gibbon, at her shoulder.

Biological Sciences Faculty Publications

Monitoring the movement of plastic into marine food webs is central to understanding and mitigating the plastic pollution crisis. Bioindicators have been a component of the environmental monitoring toolkit for decades, but how, where, and which bioindicators are used in long-term monitoring programs has not yet been assessed. Moreover, these programs have yet to be synthesized and evaluated globally. Doing so is imperative if we are to learn from these pioneering programs and expand on their efforts. We reviewed global monitoring programs using bioindicators that focus on plastic pollution and found 11 worldwide that met our definition of long-term monitoring. …

The Effect Of Need For Closure, Gender Essentialism, And Contact On Transphobia, Jacob E. Vargas

College of Education and Human Sciences: Dissertations, Theses, and Student Research

Using a motivated social cognition framework, this study explores whether there is an indirect effect of need for closure on transphobia via gender essentialism and whether this relationship is moderated by transgender contact. Data were collected from an undergraduate sample of 405 cisgender participants (n_men = 159, n_women = 246). A simple mediation and a moderated mediation were used to examine the hypothesized relationships, controlling for participant gender. Results reinforced the positive correlation between gender essentialism and transphobia and the negative correlation between transgender contact and transphobia. However, the mediation and moderation hypotheses were not supported. Need …

Examining Trauma And Substance Use Co-Morbidity In African Americans, Breanne Maray Sande Russell

Dissertations and Doctoral Documents, University of Nebraska-Lincoln, 2023–

Childhood maltreatment (CM) is a profound public health crisis that significantly elevates the risk for substance use disorders (SUDs), including alcohol and opioid misuse. Adolescents exposed to CM are especially vulnerable, often turning to substances as maladaptive coping mechanisms during critical developmental periods. African American youth bear this disproportionate burden, yet research addressing their unique experiences remains strikingly limited. Furthermore, while the co-occurrence of trauma-related disorders and substance use is well documented, racial and ethnic minority groups continue to be underrepresented in this literature. Emotion regulation difficulties are increasingly recognized as a mechanism linking PTSD symptoms with substance use, yet …

Echo Chambers On The Left, Echo Chambers On The Right: How Socioideological Identity Emotion Shape Social Interaction Behavior On Social Media, Dean Carl Jackson

Dissertations and Doctoral Documents, University of Nebraska-Lincoln, 2023–

This dissertation investigates how echo chambers emerge on social media by shifting the lens from aggregate patterns of information exposure to moment-by-moment, individual level interaction decisions between peers. I theorize that selective exposure online is not only about what content people consume or avoid, but also about selective social exposure—accepting, rejecting, or sharing with the sources of that content—guided by sociopolitical identity, ideological distance (ID), and discrete emotions. To test this, I employ two survey experiments using real tweets varying in ideological extremity and measure user’s likelihood to Block, Follow, Retweet, or reply, alongside self-reported emotional reactions and ID between …

Fire History, Ecological History, And Historical Human-Environment Interactions In The Northern Great Plains, James Victor Benes

Dissertations and Doctoral Documents, University of Nebraska-Lincoln, 2023–

This dissertation explores the spatiotemporal signatures of fire in North American grassland ecosystems. In three chapters, I explore different aspects of fire history in the northern Great Plains. Chapter 1 is an introduction. Chapter 2 focuses on the Euro-American Settlement Period (ca. 1850–1950 C.E.). Fire histories from six different lakes in the Nebraska Sandhills are compared with two periods of historic drought and the establishment of United States Post Offices. Five of the six records show increased levels of biomass burning during the initial phases of Euro-American Settlement. Chapter 3 is a long-term (ca. 15,000 years), high-resolution fire history and …

Improving Adherence In Adolescent Kidney Transplant Recipients, Kaylen Munoz

Nursing | Student Research Posters

Background: Adolescent and young adult (AYA) kidney transplant recipients face unique challenges in maintaining long-term graft function and overall health. Nonadherence to immunosuppressive therapy and difficulties transitioning from pediatric to adult care contribute to the increased risk of graft failure in this population. Despite proposed tools identifying adherence barriers, there is a lack of implementation and targeted interventions addressing the barriers AYA transplant recipients face. Purpose: This study aims to evaluate the effectiveness of a structured transition program that utilizes an adherence barrier tool and adherence-promoting interventions in improving health outcomes for adolescent and young adult (AYA) kidney transplant recipients. …
