Qualitative Beta-2-Adrenoceptor Signaling In The Regulation Of Human Airway Epithelia Mucin And Cytokine Production, Fred Graumuller, Diana Cervantes, Tung O. Chan, Niccolette Schaunaman, Dominic R. Villalba, Burton F. Dickey, Julia K. L. Walker, Hong Wei Chu, Raymond B. Penn

Division of Pulmonary, Allergy, and Critical Care Medicine Faculty Papers

BACKGROUND: Numerous in vivo studies have demonstrated beta-2-adrenoceptor (β2AR) -agonism as permissive in the development of allergic lung inflammation, and have implicated the arrestin-dependent signaling arm of the β2AR in mediating this effect. However, the specific cell type(s) mediating β2AR regulation of allergic lung inflammation remain unestablished.

METHODS: To explore the potential contribution of airway epithelia in this phenomenon, we compared the ability of ractopamine (RP), recently identified as a Gs-biased beta-agonist, to that of the unbiased/balanced beta-agonist albuterol (ALB), on IL-13-stimulated mucin and cytokine production in human airway epithelia cultures in air-liquid interface (HAE).

RESULTS: ALB, which activates both …

(Wp 2026-02) Behavioral Macroeconomics, Kaleckian Post-Keynesian Economics, And Stratification Economics: Incorporating Social Identity, John B. Davis

Economics Working Papers

Behavioral Macroeconomics draws on cognitive psychology’s errors and biases approach to argue that psychological factors acting on individual choice affect how the economy functions. Keynes drew on psychology in his ‘beauty contest’ account of convention to explain individual investor expectations in terms of the average expectation of all investors. This assumes individual investors identify with the group of all investors, anticipating social psychology social identity analysis. Kaleckian Post-Keynesian Economics focuses on distributional conflict between capital and labor. This also assumes individual capitalists and laborers identify with groups of capitalists and laborers. Stratification Economics makes social group identity the basis on …

Narrating Experience: How Undergraduate Social Work Students See Themselves In The Social Justice Curriculum, Emily C. Soener

Department of Educational Administration: Dissertations, Theses, and Student Research

Social justice is widely recognized as a foundational value of the social work profession, yet research indicates inconsistencies in how social justice is defined, taught, and experienced within social work education. This study examines how undergraduate social work students make meaning of social justice learning in relation to their own lived experiences. Using a critical narrative inquiry approach grounded in constructivist qualitative methodology, this study explores how students narrate their experiences of social justice education and how those narratives reveal tensions between professional ideals and classroom realities. Data were collected through semi-structured interviews with eleven undergraduate social work students enrolled …

Effects Of Beaver Dams On Components Of Riverscape Health And Biodiversity In The Great Basin, Cashe C. Rasmussen

All Graduate Theses and Dissertations, Fall 2023 to Present

Networks of rivers and their floodplains (i.e., low-lying areas adjacent to rivers and streams that could plausibly flood) have been degraded, reducing the availability of freshwater and habitat for people and wildlife. Therefore, land managers are pursuing cost-effective restoration strategies, including partnering with beavers (Castor canadensis), to promote the health of these ecosystems and associated benefits. However, our understanding of beaver-mediated restoration benefits remains incomplete. Here, we compared locations along streams with and without beaver dams to measure the benefits of beavers in the Great Basin of the Western United States. We measured the effects of beaver dams …

Treatment And Interventions For Sexual Assault In Humanitarian Contexts: Addressing Gaps In Refugee And Idp Camp Care In Myanmar, Erin Nash

Capstone Experience: Master of Public Health

Sexual and gender-based violence (SGBV) remains a pervasive yet under-addressed issue in humanitarian settings. Refugee and internally displaced person (IDP) camps along the Thai– Myanmar border represent a complex nexus of protracted displacement, ethnic conflict, and limited access to medical and psychosocial care. Although the prevalence of sexual assault in these contexts is well-documented, there is a critical gap in the literature regarding effective, context-specific treatment and intervention strategies. This capstone project conducts a comprehensive review of existing research on sexual assault care in humanitarian crises worldwide and assesses its applicability to displaced ethnic minorities from Myanmar.

Plan To Develop A Theory-Based Diabetes Social Media Campaign For Spanish-Speaking Adults In Finney County, Ks: Integration Of A Promotora, Focused Discussion Groups, And Community Feedback To Ensure Cultural Appropriateness, Julevi P. Bernido

Capstone Experience: Master of Public Health

The 2025 Community Health Needs Assessment (CHNA) shows that over 11% of adults in Finney County, Kansas, have diabetes, which surpasses both state and national averages. Census data from 2016-2020 indicate that 42.6% of residents ages five and older speak a language other than English at home, and 36.1% speak Spanish (United States Census Bureau, n.d.). The CHNA further highlights concerns about language and cultural barriers to care, especially among the Spanish-speaking population. Notably, 21.74% of residents have limited English proficiency—much higher than the state’s 12.1% (CHNA, 2025).

This capstone will develop a theory-based social media campaign plan to support …

Gestational Diabetes And Social Determinants Of Health In Black Women, Darianne Greenwood

Capstone Experience: Master of Public Health

Gestational Diabetes Mellitus (GDM) poses significant health risks, specifically increasing the risk of developing Type 2 Diabetes post-delivery, as well as increasing the risk of adverse neonatal and maternal outcomes. Black women, in particular, experience disproportionately higher rates of GDM incidence, severity, and complications in comparison to White women. Biological factors alone do not account for these disparities, necessitating a deeper examination into how systemic factors, particularly the social environment, influence these inequitable health outcomes. The purpose of this comprehensive literature review is to answer the question: “How do the Social Determinants of Health (SDoH), such as residential segregation, food …

A Literature Review Of Estrogen Synthesis And Metabolizing Enzymes Produced By The Human Gut Microbiome And Their Correlation With Cancer, Rebecca Cederberg

Capstone Experience: Master of Public Health

The link between estrogen and cancer initiation or progression has been well established; such that the World Health Organization’s International Agency for Research on Cancer (WHO IARC) has classified several estrogen therapies and estrogenic compounds as group 1 carcinogens. Estrogen and/or its receptors have been associated with reproductive cancers such as breast, ovarian, endometrial, and prostate, as well as lymphomas, lung, and colon cancers. Additionally, elevated levels of estrogen and altered gut microbiomes are also associated with increased rates of breast cancer. More recently, microbial genes that are capable of synthesizing estrogen and deconjugating estrogen metabolites have been identified, and …

A Common Pool Of Privacy Problems: Legal And Technical Lessons From A Large-Scale Web-Scraped Machine Learning Dataset, Rachel Hong, Jevan Hutson, William Agnew, Imaad Huda, Tadayoshi Kohno, Jamie Morgenstern

Articles

We investigate the contents of web-scraped data for training AI systems, at sizes where human dataset curators and compilers no longer manually annotate every sample. Building off of prior privacy concerns in machine learning models, we ask: What are the legal privacy implications of web-scraped machine learning datasets? In an empirical study of a popular training dataset, we find significant presence of personally identifiable information despite sanitization efforts. Our audit provides concrete evidence to support the concern that any large-scale web-scraped dataset may contain personal data. We use these findings of a real-world dataset to inform our legal analysis with …

Use Of Electroencephalography To Evaluate Neural Correlates Of Attention In The Oddball Paradigm, Folsom J. Berry

Honors Theses

Electroencephalography (EEG) and Event-Related Potentials (ERP) are tools used to study and analyze cognitive processing. EEG measures neuroelectric brain activity from the scalp, while ERPs are time-locked averages that are used to isolate neural responses to stimuli. The P300 (P3) component (positive waveform elicited at 300 milliseconds (ms)) is the primary ERP component. This thesis project had two main objectives. The first objective was to develop conceptual and technical competency in EEG/ERP theory, data acquisition, and processing. The second objective was to implement the visual oddball paradigm through experimental demonstration. This experiment tested the hypothesis that infrequent target stimuli will …

In-Vitro Testing Of Light Wavelength To Detect Clots In Neonatal Extracorporeal Membrane Oxygenation Circuitry, Amanda Holmes

Dissertations and Theses (Open Access)

Background: Neonates requiring extracorporeal membrane oxygenation (ECMO) are at high risk for thrombotic complications, which contribute substantially to morbidity and mortality. Current circuit surveillance methods rely on intermittent visual inspection and indirect laboratory markers, both of which often detect thrombosis only after clinically significant progression. Optical approaches offer a non-invasive alternative for earlier clot visualization, yet the influence of illumination wavelength on detection performance under realistic ECMO conditions remains incompletely characterized.

Methods: This study evaluated wavelength-dependent clot detection performance in a controlled in-vitro neonatal ECMO circuit model using a portable imaging prototype designed to emulate bedside workflow. Twelve independent ECMO …

Theses and Dissertations

Water treatment plants (WTPs) are vital infrastructure systems that depend on sensitive electrical, electronic, and control equipment to ensure the continuous supply of safe drinking water and effective wastewater treatment. As global temperatures rise and climate change accelerates, the frequency and intensity of extreme weather events—such as hurricanes, flooding, and increased lightning activity—are becoming more pronounced. These events pose significant risks to the electrical resilience of water treatment facilities, often leading to power outages, equipment failures, grid instability, and prolonged service disruptions. This report explores the impacts of extreme weather, with a particular focus on lightning and electrical surges, on …

Modeling Causal Interactions Across Brain Functional Systems For Population-Specific Disease Analysis, Alissen Moreno

Theses and Dissertations

Functional brain connectivity provides critical insight into neural mechanisms underlying neurodegenerative and affective disorders. Traditional neuroimaging studies rely on undirected or region-specific connectivity measures developed predominantly using racially homogeneous cohorts, limiting fairness and generalizability across diverse populations.

We propose a population-aware framework modeling directed causal interactions across large-scale brain functional subnetworks. Resting-state fMRI data from the HABS-HD cohort were used to construct subject-level causal connectivity matrices via ICA-LiNGAM, aggregated into interpretable system-level hyper-connectomes representing interactions among eleven canonical brain subsystems. These features trained nonlinear models for Alzheimer’s disease stage classification and trait worry prediction.

Results demonstrate that MLP models outperform …

Enhancing Walleye (Ogaa) Recruitment: Evaluating Assisted Reproduction As A Mitigation Strategy, Douglass Keiser

Biology Graduate Theses

Over the past several decades, cold- and cool-water fish populations across the Upper Midwest, including Minnesota and Wisconsin, have shown troubling signs of decline. Among the most affected is the walleye/Ogaa (Sander vitreus), a species deeply embedded in the ecological balance, cultural identity, and economic vitality of the region, and central to the lifeways, treaty-reserved rights, and resource stewardship of Tribal Nations, including Ojibwe communities across the Upper Midwest. Despite ongoing stocking efforts and harvest regulations, many lake systems have experienced persistent declines in natural recruitment, prompting resource agencies to investigate the underlying causes. One such system is …

Biodiversity Risk And Firm Valuation: Regional Heterogeneity And Value-Chain Exposure In Global Capital Markets, Madelein Wentzel

Doctoral Dissertations (DBA)

This study examines whether biodiversity-related risks are priced in global equity markets and whether that pricing varies across regions, using a cross-sectional sample of more than 10,000 globally listed firms with biodiversity and financial data drawn from the fourth quarter of 2025. Consistent with a regional heterogeneity hypothesis, the results show that biodiversity risk is significantly negatively associated with firm valuation in developed markets such as the United States and OECD countries, while the relationship is weaker, insignificant, or even positive in certain emerging regions including Latin America and the Middle East and Africa. The analysis further distinguishes between value-chain …

Evaluating Management Strategies And Technology To Improve Grazing Efficiency, Thomas E. Aquino

Department of Animal Science: Dissertations, Theses, and Student Research

Increasing land costs and labor constraints continue to challenge beef producers. More intensive practices can increase harvest efficiency; however, many producers are deterred from implementing them due to increased labor and management considerations. Virtual fencing (VF) may provide a reduced labor alternative to traditional fencing for managing intensive grazing. This dissertation evaluated management strategies and VF technology to improve grazing efficiency of stocker cattle systems. In Experiment 1, VF was used to effectively manage groups of steers grazing in adjacent paddocks separated by only virtual boundaries. There was no difference in VF containment (99%) when steers were grazing co-fenced, with …

Evaluation Of Palm Oil As An Ingredient In Finishing Beef Cattle Diets On Performance, Carcass Characteristics, And Meat Quality, And The Composition Of Spayed Heifers To Intact Heifers Fed Melengestrol Acetate On Feedlot Performance And Carcass Characteristics, Tate S. Johnson

Department of Animal Science: Dissertations, Theses, and Student Research

Heifers represent a large proportion of cattle placed in feedlots, making pregnancy management an important consideration for maintaining performance and carcass value. Melengestrol acetate (MGA) is commonly included in feedlot diets to suppress estrus and prevent pregnancy in intact heifers during the finishing period. Alternatively, spaying has historically been utilized as a management practice to allow heifers to graze alongside breeding cattle without the risk of pregnancy. Despite its historical use, there is limited contemporary research comparing the growth performance and carcass characteristics of spayed heifers with intact heifers managed with MGA under modern feedlot conditions. Therefore, a commercial study …

As a result, barriers to early identification and intervention of mental health challenges remain a persistent concern within the aviation industry. This ongoing study utilizes a non-experimental, survey-based design to examine the mental wellness of professional pilots worldwide and their willingness to seek mental health support. The survey includes demographic items, standardized mental …

From Reactive To Predictive: A Hybrid Trust-Mediated Adoption Framework For Data-Driven Maintenance In Distributed-Authority Aviation Environments, Dustin J. Foote

International Journal of Aviation, Aeronautics, and Aerospace

Modern aviation maintenance operates within increasingly data-intensive technological environments, yet the operational integration of predictive maintenance into routine decision-making remains inconsistent across sectors. Contemporary aircraft incorporate centralized maintenance computers and condition monitoring architectures capable of fault aggregation, exceedance capture, and trend-based data collection. Although prognostics and health management research continues to advance detection and prediction methods, implementation outcomes often depend on factors beyond analytical performance alone.

This paper examines predictive maintenance adoption in distributed-authority aviation environments and argues that constraints emerge less from sensing capability than from organizational structure, decision authority dispersion, and institutional trust dynamics. For purposes of analysis, …

Modeling Water Quality And Cyanobacteria Blooms In St. Lucie Estuary, Florida, Mohmmad Masudur Rahman

Electronic Theses and Dissertations

The St. Lucie Estuary (SLE) on Florida’s east coast is vital for diverse aquatic life and provides essential services to local communities. However, the estuary’s health is threatened by water quality deterioration due to nutrient-driven phytoplankton blooms, particularly cyanobacteria, which have increased in frequency over recent decades. These blooms may worsen water quality by reducing dissolved oxygen, altering pH, and increasing turbidity. Moreover, some phytoplankton species, including Microcystis aeruginosa, a freshwater cyanobacteria species, produce harmful toxins, posing risks to both marine aquatic life and human health in this area. Primary nutrient sources in this estuary include watershed freshwater discharges, …
