A Paleobiological And Paleoecological Analysis Of Mississippian Trilobites With Segmentation Abnormalities, April Catherine Cerami

Graduate Theses, Dissertations, and Problem Reports (ETD)

Trilobites are a well-preserved group of arthropods, with a fossil record extending from the Cambrian to the end of the Permian. Abnormalities, such as injuries or teratological defects, have been observed and described in multiple individuals, although investigating how these abnormalities occur in populations has been largely overlooked.

One possible cause of abnormalities in marine arthropods is heavy metal pollution. Such metals can leave individuals more susceptible to teratological deformities and injuries, interfering with the molting and healing process. Here, methods for analyzing elemental composition and preservation of the trilobite cuticle were refined, finding that 30 μm thin sections are …

F/Utility: A Sculptural Exploration Of Futility, Utility, And The Absurd, Asha Cabaca

Graduate Theses, Dissertations, and Problem Reports (ETD)

This thesis provides context for my MFA thesis exhibition, F/UTILITY, displayed in the Laura Mesaros Gallery at West Virginia University. My sculpture visually references various aspects of human culture, drawing from the natural environment, urban architecture, and ideas of work and play. These elements, often contradictory and incongruous, are, in fact, humorously subverted, transformed, and combined so that the resulting artwork is serious, playful, and arbitrary all at once. At the same time, the uncertain and sometimes involuntary interactivity of my work prompts a phenomenological viewer experience. My practice is informed by the philosophical and literary absurd, focusing on not-knowing …

Engaging Young Children In Art Museums Through Interactive Programming, Rebekah K. Bostic

Graduate Theses, Dissertations, and Problem Reports (ETD)

Young children can be successfully engaged in art museum programs in many ways. Rather than identifying only one pedagogical strategy that is most effective for them, it is more productive to consider how different approaches affect the experiences of children in a museum. Despite the considerable body of existing research about educational strategies for preschool children, a clear synthesis of various pedagogical methods has not been applied to art museum programming for this age group. This research project used participant observation as its methodology to conduct four case studies attempting to answer the question: “How do different museum educational strategies …

Studies have shown positive changes in articulation, prosody, voice, and listener perception measures in those with PD after clear speech instruction …

Three Essays On Local Labor Markets, David Henry Nason

Graduate Theses, Dissertations, and Problem Reports (ETD)

This dissertation consists of three essays that employ applied econometric analysis to examine issues related to local labor markets. These analyses explore three distinct sources of structural change or policy interventions and evaluate their implications for regional labor markets. I examine the impact of occupational skill endowments on regional resilience to a recessionary shock, how exposure to increases in employer skill demand affects local labor markets, and whether grants extended by an existing federally chartered regional commission have a positive impact on distressed local labor markets within its service area.

The first chapter of this dissertation studies the impact that …

Examining The Relationships Among Value Placed On Autonomy, Use Of Compensatory Control Strategies, And Suicidal Ideation In Older Adults, Catherine Huang Ju

Graduate Theses, Dissertations, and Problem Reports (ETD)

Rates of suicide in older adults are higher than those found in the general United States population. A variety of risk factors unique to older adulthood contribute to these numbers. Greater value placed on one’s own autonomy is related to suicidal ideation in older adults, but no research has yet been done to examine the mechanisms underlying this relationship. As individuals age and functional impairment increases, older adults generally engage in compensatory primary control strategies (e.g., seeking help) but those who prioritize independence and self-directedness – i.e., place a high value on autonomy – engage in fewer compensatory primary control …

Reprogramming Of Immunometabolic Functions In Brain Microvascular Endothelial Cells During Neuroinflammation: Insights From Ischemic Stroke And Sepsis, Shokofeh Rahimpourkaldeh

Graduate Theses, Dissertations, and Problem Reports (ETD)

Ischemic stroke and sepsis-associated encephalopathy (SAE) are two distinct conditions that share common pathophysiological mechanisms affecting brain microvascular endothelial cells (BMECs). Ischemic stroke results from an acute reduction in cerebral blood flow due to thrombosis or embolism, leading to energy failure, oxidative stress, and blood-brain barrier (BBB) dysfunction. SAE, a neurological complication of sepsis, arises from systemic inflammation, endothelial activation, and BBB disruption, leading to cognitive impairment and neuroinflammation. Despite their different etiologies, both conditions involve BMEC dysfunction as a central mediator of neurovascular injury. This dissertation aims to investigate the immunometabolic dysfunction of BMECs in ischemic stroke and sepsis, …

Skeletal And Dental Effects Of The Carriere Motion Appliance™ In Non-Growing Class Ii Patients: A Cephalometric Study, Anna Cathlyn Giles

Graduate Theses, Dissertations, and Problem Reports (ETD)

Background and Objectives: Dental and skeletal Class II discrepancies are commonly associated with orofacial disharmony, and therefore appear in orthodontic clinics frequently. Class II correction for adults is generally limited to camouflage treatment with extractions, Class II elastics, Class II correctors, distalization, or orthognathic surgery in severe cases. The orthodontic field is constantly innovating to find efficient and effective means to correct class II malocclusions. The Carriere Motion Appliance TM was introduced in 2004 as an effective “distalizing” appliance to be used as a non-extraction approach to Class II correction for adolescent and adult patients. Recent clinical evidence suggests that …

Multi-Scale Dynamic Modeling, Validation, And Uncertainty Quantification Of Radial Flow Fixed Bed Contactors For Co2 Capture, Ana Flávia De Alencar Arraes Monteiro

Graduate Theses, Dissertations, and Problem Reports (ETD)

One of the key sources of carbon dioxide emissions to the environment is fossil fuel combustion for power generation. Post-combustion CO2 capture using amine-based solvents is currently the most matured process. However, amines are corrosive and lead to degradation products at even moderate temperatures generating environmental pollutants, and require high energy for regeneration. Solid sorbents are a promising alternative. They possess lower regeneration energy, thermal stability, and have highly tunable porous structures with large surface area that can help in achieving high loading and high adsorption rates. This work focuses on mathematical modeling of CO2 adsorption/desorption processes using solid sorbents. …

This research demonstrates the importance of critical thinking in piano education. Grounded in the philosophical framework of Paulo Freire’s Pedagogy of the Oppressed, it explains how “dialogue” can be used to establish a collaborative teacher-student relationship. Through “praxis,” which is the integration of reflection and action, students and teachers can break free from “limit situations,” the structural constraints of reality, leading to evolution and creation.

By conducting interviews with piano teachers and students from diverse backgrounds, this research examines the differences between Western and Chinese piano education and some universal phenomena within piano pedagogy. Based on the interview findings, …

Psychophysiological Tools & Techniques To Predict Perceptual Motor Task Outcomes, Bobby Gerald Rawls Iii

Graduate Theses, Dissertations, and Problem Reports (ETD)

The process of perceiving environmental information, analyzing it, formulating a plan of action, and carrying out said plan is vital to our day to day lives. This loop occurs for every motor task we perform, from actions as simple as elbow flexion to as complex as performing surgery. As such, it is imperative to understand what physiological, psychological, and neurocognitive factors most dictate success or failure in the motor performance loop.

Prior research has shown that measures from each of these facets have strong relationships with motor performance outcomes, though these findings tended to rely on artificially produced stress in …

Therapeutic Roles For Alkaline Phosphatases To Target Intestinal Dysfunction In Mouse Models Of Experimental Sepsis And Ischemic Stroke, Rhiannon V. Macom

Graduate Theses, Dissertations, and Problem Reports (ETD)

Abstract

Therapeutic Roles for Alkaline Phosphatases to Target Intestinal Dysfunction in Mouse Models of Experimental Sepsis and Ischemic Stroke

Rhiannon V. Macom

Stroke is a disease that primarily affects the brain; however, ongoing research continues to show that stroke has far reaching systemic effects that can affect both short- and long-term recovery. The gastrointestinal tract has been shown to be affected post-stroke, and these effects are likely due to the bidirectional communication between the gut and the brain via the gut-brain-axis. Alkaline phosphatases (APs) are common membrane bound enzymes that are known to have a role in mitigating inflammation. The …

Understanding The Prevalence Of Γ-Hydroxybutyric Acid In Hair For Clinical And Forensic Applications, Collin J. Kustera

Graduate Theses, Dissertations, and Problem Reports (ETD)

Sexual assault affects over 400,000 Americans annually, including 13% of college students, yet only 2.5% of assailants face incarceration. This disparity stems from significant challenges in evidence collection, particularly in drug-facilitated crimes (DFCs). Victims often delay reporting due to fear, self-blame, or unawareness of the assault which is common in cases involving substances like γ-hydroxybutyric acid (GHB). Current forensic standards rely on blood and urine, which offer detection windows of just 48 and 120 hours, respectively. These short timeframes frequently fail to capture critical toxicological evidence, leaving investigators with only victim testimony, which the judicial system struggles to act upon …

Sexual health is a fundamental aspect of well-being and quality of life and impacts everyone regardless of age, gender, or sexual orientation, and is relevant throughout an individual’s lifespan. Occupational therapists have a valuable role in addressing sex concepts with patients; however, a lack of education and comfort level have been identified as barriers to practitioners addressing the concepts in clinical practice. This Doctoral Capstone Experience aims to answer how the topic of sexual health can be integrated into a lifespan curriculum in formal occupational therapy education. A sexual health curriculum was created and integrated into seven different classes that …

Does The Time Spent With Same-Gender Peers Matter? Gender Segregation And Attitudes About Coercive Sex In College Students, Kourtney L. Kotvas

Graduate Theses, Dissertations, and Problem Reports (ETD)

Gender segregation, or the tendency to form friendships with same-gender peers, is a common phenomenon across the lifespan (Mehta & Strough, 2009). Research suggests that same-gender peer groups reinforce traditional gender norms (Leaper, 2022), which may contribute to coercive sexual attitudes, which are beliefs that justify sexual coercion. This study examined how different measures of gender segregation, peer nomination, actual time spent with same-gender peers, and ideal time spent with same-gender peers relate to coercive sexual attitudes. These attitudes were assessed through rape myth acceptance, which reflects beliefs that minimize or justify sexual violence (Canan et al., 2023), and sexual …

Supporting The Social Emotional Needs Of Preschoolers, Giorgi Morrone

Graduate Theses, Dissertations, and Problem Reports (ETD)

Social-emotional competence is a prerequisite to school performance and participation in daily tasks. Children in West Virginia face social and emotional barriers including the effects of the opioid epidemic leading to children placed in foster care, born with neonatal abstinence syndrome, and being exposed to toxic stress in the home environment. Additionally, the COVID-19 pandemic has impacted children's social-emotional functioning due to isolation periods. Social-emotional programming can improve children's well-being, school performance, relationships, and outcomes later in life. Occupational therapy practitioners can use data-driven decision-making and relationship-centered practice to develop group-based, health-promotion social-emotional programming in the preschool setting. The purpose …

Efficient And Test-Time Adaptive Visual Object Tracking In The Wild, Ram J. Zaveri

Graduate Theses, Dissertations, and Problem Reports (ETD)

Tracking a single object, given the location at the first frame, has been an ongoing challenge in the vision community for decades. Most recent approaches provide reasonably good performance, especially when benchmarked on in-distribution (ID) datasets, i.e., on the testing portion of the same datasets used for training. However, they incur high computational costs and hardware constraints, making their deployment in the wild for mobile, autonomous, and IoT applications still challenging. Efficient visual trackers address the efficiency aspect of such bottlenecks; however, they tend to overfit to their training distributions and lack generalization abilities, resulting in them performing well on …

Fabrication And Characterization Of Cast Copper Heatsinks For Computer Chip Cooling, John James Recktenwald

Graduate Theses, Dissertations, and Problem Reports (ETD)

Humanity has worked copper for millennia, from primitive tools in prehistory to the wires and cooling solutions facilitating the modern digital age. While high performance fin style heatsinks are commonplace, more complex heatsink geometries in high performance applications are rare due to manufacturing challenges. In this study a casting process was developed to fabricate copper pin fin heatsinks. To assess the performance of heatsinks fabricated using the process three pin fin heatsinks were fabricated, one machined from a commercially manufactured billet, one machined from a cast block, and one cast directly to final shape. Each of the three heatsinks were …

Romantic Materialities And The Politics Of Care: Negotiating Movement In A More-Than-Human World, April J. Mcginnis

Graduate Theses, Dissertations, and Problem Reports (ETD)

This dissertation explores the ecological politics of movement in Romantic literature. It contributes to a growing body of scholarship that investigates the important role that walking played in nineteenth-century literary culture. Many authors from this period cast walking as a practice that frees up not only the body but the mind as well, as the steady rhythm of the feet lulls the walker into a state of self-absorbed introspection and heightened creativity. Because of this, walking was a celebrated part of the creative process for many writers. The freedom they celebrate is possible, however, only in spaces that are level, …

The Quick Dash Reformed: Increasing The Holisticity And Occupational Nature Of Upper Extremity Therapeutic Evaluation, Lauren E. Garcia

La Valse And The Parisian Salon: Nostalgic Continuities And Sonorous Modernisms, Claire Weydt

Graduate Theses, Dissertations, and Problem Reports (ETD)

Immediately following World War I and the death of prominent French composer Claude Debussy, French composers and music critics were concerned that the war created an unbridgeable chasm between generations of composers who, through their various aesthetic allegiances, worked to define musical sounds as undeniably French. Numerous scholars have characterized this process as an aesthetic rupture brought on by the World Wars. French composer Maurice Ravel (1875-1937), however, seems to have bridged this gap, at least for some influential critics. My project challenges notions of wartime rupture by resituating musical modernism within a framework of aesthetic continuity. Ravel’s choreographic poem …

Inactivation Kinetics Of Escherichia Coli And Listeria Monocytogenes In Edible Insects, Precious Aduloju

Graduate Theses, Dissertations, and Problem Reports (ETD)

The use of automated systems for agriculture is integral to keeping the food supply secure. Both industry and academia are exploring and applying methods to increase the yield of plants in environments ranging from outdoor fields to greenhouses. Specifically, many automated systems use continuous monitoring of plants to track plant health and yield. The use of computer vision is necessary when it comes to precision operations that use robotics. Today, robots are trained to weed, harvest, and pollinate. To accomplish these tasks autonomously, a lot of data is needed, which is where spatial-temporal observations of the plants are being recorded …

The Economics Of Substance Use: Treatment, Intervention, And Regulation, Christine Bretschneider-Fries

Graduate Theses, Dissertations, and Problem Reports (ETD)

Substance use in the United States has remained an area of concern with rates of overdose deaths increasing steadily over the years. Historically, the United States has relied on abstinence based treatment options for individuals with substance use disorder. Economists have long been interested in the affects of various supply and demand side policy interventions to help reduce the instance of substance use disorder, especially following the prescription opioid crisis of the 1990s and early 2000s. Supply side policies are most commonly enacted as a way to reduce the supply of illicit substances that enter the market. However, these supply …

Sensory Integration In The Intensive Care Unit Environment, Kara M. Lee

Graduate Theses, Dissertations, and Problem Reports (ETD)

Those admitted to the intensive care unit (ICU) commonly experience deficits in areas linked with cognition, mental health, and physical functioning (Rapolthy-Beck et al., 2023). Delirium is the most common complication among individuals who are mechanically ventilated, which can be associated with adverse outcomes, including increased mortality, cognitive decline, and decreased functional outcomes (Martinez et al., 2017). The primary purpose of the capstone project was to create a sensory-based program for patients admitted into the ICU. The program aimed to enhance the quality and consistency of care, ultimately reducing the prevalence of delirium. By doing so, it seeks to improve …
