Teaching Leadership In The Context Of Crisis: Connecting Organizational Leadership And Crisis Competencies In A Faculty Leadership Education Program, Caitlin Lunzmann, Nicole Lamee Perez Stedman, Matthew Sowcik

Journal of Human Sciences and Extension

This research focused on enhancing leadership instruction in colleges of agriculture. A multi-institutional research team initiated a program to teach agricultural and natural resource faculty how to create leadership-oriented case studies for undergraduates. Forty faculty members participated in an online training academy centered on Bolman and Deal’s Organizational Frames and case study writing. Following the academy, these faculty members participated in field experiences in the southeastern U.S. to gather data on natural disasters, which they used to write case studies about leadership in agriculture. Though the program focused on organizational leadership, it also discussed leadership in the context of natural …

The Price Of Priorities: How Human Choices Fuel Climate And Ecological Decline, Keisha Hickman

Biological Sciences Undergraduate Honors Theses

This thesis examines the ways in which human priorities and behaviors contribute to the escalating climate crisis and ecological systems. We will first analyze the role of social media in shaping public discourse on climate change and critically evaluate the priorities of institutions that have the means to assist in wildlife conservation. Both speak to the current behaviors of humankind prioritizing their own entertainment over meaningful efforts to mitigate climate change and preserve biodiversity. We will then shift to exploring the profound impact of human population growth and its associated activities on other species and ecosystems. Finally, the thesis will …

Molecular Dynamics Simulations Of Biologically Relevant Interfaces: From Tear Film Lipid Layers To Rna Adsorption On Silica Surfaces., Mahbuba Khanom

Electronic Theses and Dissertations

Molecular dynamics (MD) simulation is an important tool in biochemical sciences for studying complex molecular processes and interfacial interactions at the molecular level. Biological interfaces play key roles in processes such as ocular lubrication and biomolecular adsorption. This dissertation studies interfacial phenomena involving two distinct yet conceptually related systems: the tear film lipid layer (TFLL) at the air–water interface at the surface of the human eye, and RNA adsorption on silica surfaces. These studies provide insight into how interfacial composition, structure, and environmental conditions affect larger-scale behavior. Atomistic MD simulations were used to model the TFLL. The TFLL is essential …

Experiences Of Research Administrators With Faculty Researchers In Sponsored Project Compliance., Adrienne M. Lindsay

Electronic Theses and Dissertations

The purpose of this study was to examine how central office research administrators perceive and describe their professional interactions with faculty researchers, and how those relationships may impact compliance with sponsored project requirements in United States higher education institutions. Cohen et al.’s (1972) organized anarchy theory and Schein’s (2010) organizational culture theory provided a foundational context for understanding research systems within higher education institutions and the social environment in which research administrators navigate potentially contentious roles, both facilitating research and stewarding compliance for the institution and the sponsor. Findings emerged around specific challenges faced by research administrators, which included role …

Impacts Of Biology Modeling Pedagogy On Student Cogitive And Non-Cognitive Elements Of Learning., Jessie K. Newhouse

Electronic Theses and Dissertations

This dissertation employed a quasi-experimental design used to investigate the use of a modeling pedagogy in high school biology. Modeling is a key element of the Science and Engineering Practices of the Next Generation Science Standards. While research of Model Based Pedagogy (MBP) in physics and chemistry is well established, the influence on biology instruction remains less understood. This research examined how MBP affected both cognitive and non-cognitive components of student learning compared to traditional biology instruction. Existing data collected by Dr. Kathy Malone in collaboration with Ohio State University (2016) were analyzed to study the effectiveness of the MBP. …

Controlling Selectivity In Electrocatalytic Co2 Reduction With An External Magnetic Field., Nawaraj Karki

Electronic Theses and Dissertations

My dissertation describes how to alter the speciation and concentration of molecules at the electrode-electrolyte interface, and how those alterations affect reactivity and selectivity. This dissertation presents two distinct approaches to control the mass transport of neutral molecules such as carbon dioxide (CO₂) at the electrode-electrolyte interface by using an external magnetic field. The first finding demonstrates that magnetic fields indirectly affect the mass transport of target analytes such as CO₂ molecules by selectively interacting with charged species, such as hydroxide ions (OH^-). Such interaction induces magnetohydrodynamic (MHD) effects, which generate localized hydrodynamic flow and …

Integration And Modulation Of Visual Signals In Dorsal Thalamus., James Whitley

Electronic Theses and Dissertations

The visual thalamus is influenced by a diverse array of cortical and subcortical inputs that shape how information is transmitted to cortex. Using a variety of anatomical, optogenetic, and in vitro physiological techniques I investigated the differential impacts of modulation and integration of first and higher-order thalamic nuclei, while relying on influential concepts on the general organization of thalamic nuclei. In the first data chapter, I determined how GABAergic pretectum (PT) projections to the dorsal lateral geniculate nucleus (dLGN) and visual thalamic reticular nucleus (vTRN) can influence retinogeniculate signal transfer. We found that the PT provides over 75% of the …

The Role Of Fast-Food Consumption, Residential Fast-Food Exposures, And Urinary Essential Trace Heavy Metals In Colorectal Cancer (Crc) Outcomes., Jeevan Adhikari

Electronic Theses and Dissertations

Background: Colorectal cancer (CRC) is a public health concern. Within the United States (US), fast-food consumption and environmental exposure to heavy metals have increased. The impact of fast-food consumption frequency from fast-food restaurants, residential fast-food exposures, and urinary essential trace heavy metals in relation to CRC outcomes have not yet been rigorously evaluated in the US. Methods: Within the LEAPS-CRC study, we used geographic information systems (GIS) and logistic regression to study the association of fast-food consumption, residential proximity to a fast-food outlet, and urinary essential trace metals with CRC incidence. Additionally, within Kentucky Cancer Registry (KCR) CRC cases, the …

Genetic Identification Of A Rapidly-Adapting Low-Threshold Mechanoreceptor Innervating Fungiform Papillae., Thomas Alexander Myers Ii

Electronic Theses and Dissertations

Mechanosensory innervation of the oral cavity enables us to detect the texture and location of the foods we consume. Our goal was to find a genetic identifier for a mechanoreceptive subtype. Toward this goal, we examined neurons expressing the neurotrophin receptor TrkC, parvalbumin (Pvalb), and the glutamate transporter Vglut3. Because different papilla types contribute to food detection in different ways, we examined the innervation patterns of these neuron subtypes. We found that Pvalb+ and Vglut3+ neurons were fungiform papilla specific, where TrkC innervated both papilla types. We examined the anatomy of the three genetic populations, finding that the Pvalb+ neurons …

Characterizing Hexavalent Chromium Neurotoxicity Across Laboratory Models., Samuel Thomas Vielee

Electronic Theses and Dissertations

Hexavalent chromium [Cr(VI)] is a ubiquitous environmental pollutant and potent toxicant. Exposure to Cr(VI) in drinking water is primarily associated with cancers, inflammation, and hepatotoxicity; however, recent studies have identified Cr(VI) as a neurotoxicant in rodent and cell culture models. The literature suggest chromium accumulates in the brain, induces widespread neurodegeneration, and alters rodent behaviors. Despite these data, we lack a detailed and consistent assessments of Cr(VI) neurotoxicity across models, and interactions between aging and Cr(VI) neurotoxicity are not reported in the literature. In this dissertation, we characterize Cr(VI) neurotoxicity across 3 laboratory models: Sprague-Dawley rats, Caenorhabditis elegans, and …

Exposure To Pm2.5 And Aging., Daniel Chris Gomes

Electronic Theses and Dissertations

Inhalation of fine airborne particulate matter (PM_2.5) is an environmental risk factor for numerous health disorders, including cardiovascular diseases (CVD). While several studies have shown that PM_2.5 exposure can induce oxidative stress, DNA damage, and inflammation, the underlying mechanisms that translate these effects into systemic pathology remain poorly understood. Some recent studies have shown that PM_2.5 exposure can lead to telomere shortening in leukocytes, but the generality of this outcome and contribution to endothelial dysfunction has not yet been fully explored. We hypothesized that PM_2.5inhalation accelerates cellular aging and senescence in both circulating peripheral …

Increasing Histidyl Dipeptides In Skeletal Muscle Preserves Muscle Mass And Function In Heart Failure., Mamata Hiraman Chaudhari

Electronic Theses and Dissertations

Introduction: Heart failure is a systemic disease associated with multiple comorbidities, such as skeletal muscle wasting and cardiopulmonary disease. Muscle wasting in heart failure patients is a severe comorbidity associated with decreased exercise capacity and poor quality of life. Previous reports show that oxidative stress is increased in the skeletal muscle of heart failure patients, which can directly lead to muscle wasting. However, antioxidant intervention in these patients was unable to improve cardiac function and consequently had no effect on muscle wasting. Although oxidative stress is the primary driver of skeletal muscle atrophy, no attempt has been made to examine …

Identifying Correlates Of Protection Of A Pneumonic Plague Vaccine., Caleb Samuel Whitley

Electronic Theses and Dissertations

Pneumonic plague is caused by inhalation of the bacterial pathogen Yersinia pestis. The immune response during Pneumonic plague occurs in two phases; an initial asymptomatic phase followed by a highly inflammatory and destructive phase resulting in 100% mortality if left untreated. The rapid onset of severe disease following the asymptomatic phase makes it difficult to administer antibiotics in time to prevent lethal outcomes. Therefore, the development of an effective vaccine is likely needed to combat pneumonic plague in areas of the world where Y. pestis remains endemic. One candidate subunit vaccine is protective in mice, a natural host for …

Direct And Satellite-Based Quantification Of Greenhouse Gas Fluxes In Small Ponds., Mark Christopher Tierney

Electronic Theses and Dissertations

As evidenced by their historic losses due to anthropogenic activities, wetlands are undervalued ecosystems that provide numerous ecosystem services, from recreational opportunities to carbon (C) storage. However, these wetlands are also the largest natural source of atmospheric methane (CH₄). Additionally, small water bodies (< 10,000 m²) are disproportionately large emitters relative to larger lakes and reservoirs. As construction and restoration efforts proceed, it is crucial to identify wetlands that need restoration and to understand the factors driving both greenhouse gas (GHG) fluxes and the C balance of these systems. This dissertation investigates the drivers of greenhouse gas fluxes …

Sensory And Motor Tectothalamic Circuits: Two Sides Of The Same Coin., Nazratan Naeem

Electronic Theses and Dissertations

Integration of sensorimotor information in the visual system has always been an intriguing topic to scientists, yet the subcortical sensory and motor circuits that are essential components of this process have remained elusive. In these studies, we used a blend of classical and contemporary techniques such as viral tracing, immunohistochemistry, optogenetics in-vitro whole cell electrophysiology, and electron microscopy in mice to characterize sensory and motor circuits of the superior colliculus (SC), a conserved visuomotor structure with connections with a wide variety of brain structures, including the thalamus. We focused on two SC cell types: visually responsive widefield vertical (WFV) cells …

The Autonomic And Arrhythmogenic Effects Of Gestational E-Cigarette Exposure., Brittany Rachelle Reynolds

Electronic Theses and Dissertations

Introduction. E-cigarettes (e-cigs) have been shown to be pro-arrhythmic in both human and male rodent studies; however, little is known about how e-cig use impacts patients with a predisposed heightened risk for arrhythmias, including pregnant women. Both pregnancy and e-cig use have independently been shown to increase heart rate, diminish heart rate variability, and increase ventricular premature beats, which is suspected to be due to sympathetic dominance. Importantly, β-blockers have been shown to reduce sympathetic activity, reduce heart rate, increase HRV, and reduce arrhythmias. Thus, the use of β-blockers may help prevent adverse health effects driven by sympathetic dominance from …

Tumor Infiltrating Lymphocytes: From Discovery To Clinical Application., Lewis Clayton Chew

Electronic Theses and Dissertations

Adoptive cell therapy (ACT), particularly TIL therapy, has emerged as a promising alternative to traditional treatments like chemotherapy. This review article traces the historical development of TILs, highlighting key experiments and clinical trials that have shaped its understanding and application as a therapeutic strategy for patients with metastatic and difficult to treat cancers including melanoma. Importantly, this article highlights recent advancements, including the FDA approval of Lifileucel, and explores emerging strategies to enhance therapeutic efficacy of TILs through …

An Arendtian Politics Of Life, Kamryn M. Carter

Senior Theses

As defined in The History of Sexuality (1978), Michel Foucault’s concept of biopolitics focused on a specifically modern phenomenon in which biological processes are used to regulate populations. This concept has been influential in modern analyses of the state such as that of Giorgio Agamben, who sought to both correct and complete biopolitics with his concept of homo sacer as part of his analysis of the concentration camp. This thesis brings the theory of biopolitics into conversation with Hannah Arendt’s politics of life. It seeks to determine the degree to which biopolitics — as seen in the work of Michel …

Prostitution In Video Games: Stigma, Violence And Male Pleasure, Laura Aguilera-Ávila, Lara Escobar Hernández

Dignity: A Journal of Analysis of Exploitation and Violence

Prostitution has traditionally been framed in society as a space significantly determined by patriarchal hierarchies, in addition to being affected on many occasions by stigmatisation and violence. The representation of prostitution and of those who practice it in the media is a topic of special interest, since the discourses and messages disseminated by the media play a fundamental role in socialisation. Video games are not exempt from this debate: with millions of players worldwide and a special reach among young people, they are among the most influential media outlets today. This qualitative research analyses a series of titles, both AAA …

Impact Of Rendering Wastewater Variability On Electrocoagulation - Electroflotation, Katie L. Hardison

All Theses

Rendering is a resource recovery technique commonly utilized to recover fats and proteins from unused animal parts discarded during meat processing and slaughter. Resource recovery involves converting waste products into valuable products. Rendering generates large volumes of heavily polluted wastewater. Pollutant concentrations can vary significantly, although rendering wastewater (RW) has extremely high concentrations of fats, oils, and greases (FOG). To remove pollutants, first chemicals called coagulants are added to RW to encourage pollutants to clump together to form flocs. The flocs are then floated to the surface and removed through the addition of air in a process called dissolved air …

Inflammatory And Metabolic Markers In Postpartum Dairy Cows Developing Chronic Reproductive Tract Disease: A Case-Control Study, T.C. Bruinjé, O. Bogado Pascottini, S.J. Leblanc

Dairy Science and Food Science Faculty Publications: 2022 to Present

We investigated associations of early postpartum sys- temic inflammatory and metabolic markers with different manifestations of chronic reproductive tract inflamma- tory disease (RTID) in Holstein cows. A retrospective case-control study was conducted using data from 1,509 cows in 2 commercial dairy herds in Ontario, Canada. Herds were visited twice weekly, and cows were sampled at 2 and 6 ± 2 DIM to measure serum haptoglobin (Hp), total Ca, and nonesterified fatty acids; at 5, 8, 11, and 15 ± 2 DIM for blood BHB; and at 21 and 35 ± 3 DIM for serum Hp. Cows with a calving-related or …

First-Hand Perspectives Of Autistic And Neurodiverse Individuals In Social And Extracurricular Settings, Stephen M. Hinkle

Education (PhD) Dissertations

This dissertation explores the firsthand experiences of autistic and neurodiverse individuals in social and extracurricular settings. Grounded in symbolic interactionism and disability studies, this study leveraged qualitative interviews to provide greater insight into the extracurricular lives of autistic persons and the quality of preparation and education provided to said participants to successfully navigate those experiences. Due to the limited number of studies on this topic, and the tendency of programs to focus on general skill development for this population, significant attention was also given to investigating the activity-specific skills needed for various social and extracurricular activities.

Characterization Of Free Oxylipins In Extracellular Vesicles From Bovine Milk, Kai Filio

Food Science (MS) Theses

Background. Extracellular vesicles (EVs) are membrane-bound nanostructures released by human and bovine mammary epithelial cells that carry bioactive lipids and oxidized lipid metabolites. Found in bovine milk, EVs contribute to immune modulation, gut health, and cellular signaling. However, gaps remain in understanding the full composition of milk-derived EVs and how processing alters EV content. This research aimed to characterize the free oxylipin content of EVs from bovine milk treated by pasteurization and homogenization. The hypothesis was that EVs from raw bovine milk would retain higher oxylipin levels than processed milk. Methods. Raw milk was treated by high-temperature short time (HTST), …

First Definitive Records Of Hermit Thrush And Wilson’S Warbler Subspecies For Nebraska, Stephen J. Brenner, Joel G. Jorgensen

Nebraska Bird Review

During the fall of 2025, we initiated a pilot migratory bird-banding project in the Nebraska Panhandle. While the project’s goals included examining species composition, volume, and body condition of migratory birds at the western edge of the state compared to the eastern edge of the state, we also used this project to document the occurrence of subspecies and species which are very challenging or impossible to identify through field observation. Here, we report on the first definitive records of two subspecies in Nebraska.

On 16 September 2025, SJB banded an adult male Wilson’s Warbler (Cardellina pusilla) that was …
