Evaluation Of Potential Factors Limiting The Expansion Of Invasive Carp (Hypophthalmichthys Spp.) In The Ohio River Basin, Erin Shepta

Graduate Theses, Dissertations, and Problem Reports (ETD)

The introduction of aquatic invasive species is one of the greatest threats to freshwater biodiversity around the world. Two species of invasive carp, bighead carp (Hypophthalmichthys nobilis) and silver carp (H. molitrix) have spread throughout much of the Mississippi River Basin, resulting in serious ecological impacts to native communities. Their spread in the Ohio River, a major tributary of the Mississippi River, appears to have slowed, with limited evidence of upstream advancements. Here, we investigated abiotic and biotic factors that may be contributing to the reduced spread of invasive carp in the Ohio River Basin. Generally, …

Exploring The Intersectionality Of Sociodemographic Factors And Adverse Childhood Experiences That Impact College Performance, Taylor June Brown

Graduate Theses, Dissertations, and Problem Reports (ETD)

Success in higher education is influenced by a range of social and economic factors that do not affect all students equally. This thesis examined how Adverse Childhood Experiences (ACEs), socioeconomic status (SES), first-generation college status, minority status, and geographic isolation independently and multiplicatively relate to academic outcomes. Using data from 775 first-year students at a large public university in rural Appalachia, this study assessed whether these factors independently and/or multiplicatively predicted first-year GPA and odds of dropping out. ACEs linearly predicted first-year cumulative GPA and odds of dropping out. A significant ACE x Race interaction emerged for predicting first-year cumulative …

Feasibility Of Parent-Child Interaction Therapy-Toddler In Community Clinics In The United States And Japan, Sharon T. Phillips

Graduate Theses, Dissertations, and Problem Reports (ETD)

The toddler age (12-36 months) is characterized by a toddler’s increasing desire for autonomy, which can result in caregiver-child conflict and toddler externalizing problems (Kohlhoff & Morgan, 2014). Clinical levels of disruptive behavior in toddlerhood can be predictive of a host of negative outcomes, including problems with academic achievement and delinquency (Copeland et al., 2007; Milledge et al., 2019). High levels of toddler behavior problems also are associated with poor caregiver-child relationships and poor toddler emotion regulation skills (Beijers et al., 2013; Umemura et al., 2022). Thus, interventions targeting toddler behavior problems need to focus on strengthening the caregiver-child relationship …

Do Transdiagnostic Factors Predict Emotion Recognition?, Grace L. Wheeler

Graduate Theses, Dissertations, and Problem Reports (ETD)

While emotion recognition deficits have been found in several anxiety and related disorders (e.g., social anxiety, obsessive-compulsive), consistent results have not been established. To clarify the relationship between emotion recognition abilities and anxiety, the current study tested if transdiagnostic factors related to anxiety are predictors of emotion recognition abilities. Data was analyzed from participants (N = 188) recruited via CloudResearch; they completed measures of three transdiagnostic factors related to anxiety (e.g., anxiety sensitivity, intolerance of uncertainty, and rumination), followed by an emotion recognition task. Multiple regression analyses revealed higher levels of anxiety sensitivity predicted worse recognition for anger, disgust, …

Improving Sedative Administration In Patients Receiving Paralytics During Intubation: A Quality Improvement Initiative Within A Large Academic Medical Center In West Virginia, David Bryon Underwood

Graduate Theses, Dissertations, and Problem Reports (ETD)

Introduction: Awake paralysis (AWP) occurs when long-acting neuromuscular blockers outlast short-acting sedatives during intubation, leaving patients chemically paralyzed but conscious. This highlights the critical need for timely post-intubation sedation.

Background: A 2024 review in the Neurological Critical Care Unit (NCCU) revealed that 72% of patients who received rocuronium were not given a post-intubation sedative. The difference in duration of action of paralyzing agents versus sedatives can result in patients being conscious while paralyzed, potentially resulting in hemodynamic instability and psychological harm.

Purpose: The quality improvement initiative aimed to reduce the number of patients receiving neuromuscular blocking agents without post-intubation sedation. …

Three Essays On Personnel And Labor Economics, Chengyuan Hua

Graduate Theses, Dissertations, and Problem Reports (ETD)

Labor market dynamics are not only relevant for worker welfare, but also matter for firm productivity. This dissertation investigates the dynamic interactions between firms and workers, with a particular focus on the determinants and effects of human resources management practices. Using professional sports labor markets as a natural laboratory, I examine three distinct but interconnected mechanisms: managers, hiring decisions, and contract setting.

The first chapter studies how managers matter for worker productivity by exploiting manager moves in Major League Baseball. I first show that manager effects are primarily match-specific using an AKM-type model. Then, staggered difference-in-differences results show positive effects …

Electronic Cigarettes Increase Blood-Brain And Blood-Tumor Barrier Drug Efflux In A Preclinical Lung Cancer Model Of Brain Metastasis, Cullen Parker Wolford

Graduate Theses, Dissertations, and Problem Reports (ETD)

This dissertation (a) provided a comprehensive review of the known therapeutic challenges in nicotine delivery system users with lung cancer and (b) investigated the impact of electronic cigarettes on blood-brain/blood-tumor barrier function and efficacy of small molecule KRAS inhibitors in a syngeneic lung cancer brain metastasis model. The blood-brain barrier is a physiochemical barrier that limits systemic delivery of therapeutics into brain. When tumors invade the central nervous system, the blood-brain barrier is disrupted and subsequently forms a blood-tumor barrier. Despite the inherent leakiness and variable permeability of the blood-tumor barrier, it continues to restrict anti-cancer drugs from accumulating at …

Studying The Mechanism For Ricin-Induced Growth Suppression, Daniel Judge

Graduate Theses, Dissertations, and Problem Reports (ETD)

This study focuses on ribosome-inactivating proteins (RIPs), a class of potent toxins that includes ricin, α-sarcin, and shiga toxin, which irreversibly damage large subunit rRNA. Although the catalytic activity of ricin toxin A chain (RTA) is well characterized, the precise mechanisms linking ribosome damage to altered cellular morphology remain poorly understood. In this study, we engineered a tetracycline-regulatable expression system to express RTA in Saccharomyces cerevisiae. We characterized the effects of RTA expression on yeast growth, viability, and reproductive potential. We demonstrated that our expression system produced rapid and robust RTA expression and ribosome depurination within less than one …

Optimization Of The Cmc Algorithm, Christopher Joseph Moner

Graduate Theses, Dissertations, and Problem Reports (ETD)

Cartridge cases recovered from discharged firearms contain tool marks produced by the internal mechanisms of said firearm. Firearm and tool mark examiners com pare these marks to determine whether two cartridge cases originated from the same firearm. Traditional comparison methods have been criticized for their subjective nature and reliance on examiner interpretation rather than objective decision thresholds. The Congruent Matching Cells (CMC) algorithm was developed as a quantitative, objective method for tool mark comparison. CMC is a surface topography correlation algorithm that partitions a tool mark into small regions, or cells, and evaluates their similarity using the areal cross-correlation function …

New Fossil Mygalomorph Spiders (?Idiopidae, Pycnothelidae) From The Lower Cretaceous Crato Formation Of Brazil, Elis Maria Gomes Santana

Graduate Theses, Dissertations, and Problem Reports (ETD)

The infraorder Mygalomorphae represents one of the earliest-diverging lineages of spiders, but its fossil record remains sparse relative to the modern diversity of the group. This is a reflection of both ecological and preservational biases, such as the predominantly fossorial habits of many mygalomorphs and the strong bias of the spider fossil record toward amber deposits. Compression fossils from rock deposits are therefore especially important for documenting the evolutionary history of the group. Here, two new mygalomorph fossils from the Lower Cretaceous Crato Formation, Araripe Basin (Brazil) are described. The first specimen is tentatively referred to ?Idiopidae based on male …

Population Dynamics And Future Viability Of The Eastern Massasauga Rattlesnake (Sistrurus Catenatus) In Southwest Michigan, Matthew John Klein

Graduate Theses, Dissertations, and Problem Reports (ETD)

Managing at-risk species or populations requires understanding the demographic and genetic drivers of long-term population trends. The eastern massasauga rattlesnake (Sistrurus catenatus) is a federally threatened species facing multiple interacting threats across its range. Habitat loss from wetland drainage and agricultural land conversion has caused range contractions and geographic isolation of populations. Because remaining populations are often small and widely separated, most are now genetically isolated, threatening their long-term viability. Reversing these declines requires understanding population dynamics, quantifying extinction risk, identifying drivers of long-term viability, and assessing the effects of inbreeding and the potential for genetic rescue to …

‘She Dared Not’: Authority In The Monasteries Of The Diocese Of Lincoln, 1400-1540, Morgan Mcminn

Graduate Theses, Dissertations, and Problem Reports (ETD)

Within monastic life, the Benedictine Rule prioritized the role of the abbot, and much of the everyday running of the house was left to his discretion. He was the elected father of the community, the pastor of the flock, the educator who instructed by word and example. He should discipline firmly but be loved and not feared, and he should play no favorite but rather adapt to the situation at hand. His brethren should obey him without question as the representative of Christ in the monastery, their self-will and earthly possessions submitted to him. These elements are also present in …

Landscape As Expo: Reimagining Desert Landscapes As Climate-Adaptive Cultural Infrastructure In Las Vegas, Parinaz Baradaran Anaraki

Graduate Theses, Dissertations, and Problem Reports (ETD)

Contemporary desert cities face increasing environmental and social challenges driven by climate change, including extreme heat, water scarcity, fragmented ecological systems, and limited access to high-quality public open space. In many rapidly urbanizing regions, conventional urban development has marginalized desert landscapes, treating them as vacant land rather than valuable ecological and cultural assets. This thesis proposes Landscape as Expo as a new framework for transforming desert landscapes into climate-adaptive cultural infrastructure, where ecological processes become both functional systems and public experiences.

The project focuses on a 140-acre site within the Tule Springs Planning District in North Las Vegas, Nevada, identified …

Development And Validation Of A Multi-Output Neural Network-Based Virtual Temperature Sensor For Electric Vehicle Thermal Management, Dalton Michael Wiggins

Graduate Theses, Dissertations, and Problem Reports (ETD)

Battery electric vehicles (BEVs) rely on accurate thermal management to ensure component performance, efficiency, safety, and long-term durability. Critical propulsion system components, including electric motors and high-voltage battery packs, are commonly monitored using physical temperature sensors. However, these sensors increase system cost, introduce additional hardware complexity, and may be impractical for directly measuring temperatures at critical internal locations. Virtual temperature sensors (VTSs) provide a software-based alternative by estimating component temperatures using readily available vehicle operating data.

The Tax Governance Triangle: An Attitudinal Theory Of State Capacity And Tax Compliance., Abdul Wahid Uqaily

Graduate Theses, Dissertations, and Problem Reports (ETD)

The Tax Governance Triangle: An Attitudinal Theory of State Capacity and Tax Compliance

Abdul Wahid Uqaily

Variation in states' extractive capacity is a central puzzle in comparative politics and political economy. Existing scholarship explains this variation largely through institutional quality, administrative capability, or coercive enforcement, with less attention to the attitudinal foundations that shape key actors' willingness to sustain an effective fiscal system. This dissertation addresses that gap by asking: how do the attitudes and behaviors of citizens, bureaucrats, and elites shape variation in a state's extractive capacity?

To answer this question, the dissertation develops the “Tax Governance Triangle” and …

Examining Drivers Of Brook Trout (Salvelinus Fontinalis) Fecundity And Recruitment In Central Appalachian Headwater Streams, Emilee Esther Briggs

Graduate Theses, Dissertations, and Problem Reports (ETD)

The persistence of fish populations depends on the repeated production and survival of new year classes, also referred to as recruitment. Recruitment is broadly defined as the number of individuals in a fish population or stock that survive to a specific stage. However, the broader recruitment process reflects the cumulative outcome of many earlier life stages, including egg survival, fry emergence, and survival through the recruitment period. As a result, recruitment can vary substantially among years and populations, producing strong or weak year classes that influence population abundance and persistence. Understanding why recruitment varies is therefore central to fisheries ecology …

Graduate Theses, Dissertations, and Problem Reports (ETD)

Navigating the transition to adulthood presents unique challenges for young adults with epilepsy, particularly concerning stigma and the fear of disease disclosure. While significant social difficulties, such as increased unemployment rates and decreased relationship satisfaction, are prevalent among individuals with epilepsy, current transition programs often fail to address these psychological and social aspects that are vital for an independent adult life. Instead, the majority of the attention for young adults transitioning into adulthood is focused on the shift to adult-oriented healthcare systems. Consequently, there is a critical need for research that goes beyond a healthcare focus and explores the social …

Innovative Strategies For Stabilizing Zinc Anodes: From Molecular Design To Practical Zinc-Ion Batteries, Nhat Anh Thi Thieu

Graduate Theses, Dissertations, and Problem Reports (ETD)

Aqueous zinc-ion batteries (AZIBs) have become increasingly attractive as grid-scale energy storage solutions due to their safety, low cost, and environmental friendliness. However, the anode-electrolyte interface in AZIBs is prone to instability due to severe dendrite growth, self-corrosion, parasitic water-induced side reactions, and hydrogen evolution reactions (HER), which collectively lead to poor cyclability. To date, various interfacial engineering strategies have been investigated to address these challenges and improve the stability of Zn metal anodes. This dissertation presents a unified strategy for regulating Zn deposition through synergistic electrode and electrolyte design in laboratory-scale coin cells and then applies these concepts to …
