Effects Of Ordered Eating On Various Postprandial Measures, Brian K. Ferguson

Human Movement Studies & Special Education Theses & Dissertations

Postprandial glucose (PPG) is an indicator of acute and chronic overall health, and aberrations in glucose, insulin, and other postprandial (PP) markers are common in obesity and cardiometabolic disorders. Chronically elevated glucose can lead to a number of health problems such as type 2 diabetes mellitus. Additionally, PPG responses can impact substrate utilization responses to exercise, which may have implications for both healthy and diseased populations. One potentially simple lifestyle modification to alter PPG and related markers is to change the order in which foods are consumed within meals. The purpose of this dissertation was to further explore the impact …

A Kinematic Analysis Of The Shoulder During The Volleyball Attack Using Euler And Helical Axis Methods, Victoria Jolliff

Biomedical Engineering Theses & Dissertations

The shoulder is a complex joint with a wide range of motion, including flexion, extension, abduction, adduction, and internal and external rotation. In volleyball, repetitive overhand movements can cause shoulder overuse injuries. The primary offensive move, the attack, involves the approach, arm cocking, arm acceleration, and follow-through phases. Motion capture analysis and techniques like calculating Euler angles and rotation about a mean helical axis can evaluate shoulder movements. This study aimed to calculate shoulder movements during each phase of the volleyball attack using the Euler angle YXY sequence and the helical axis method. Different attack types, such as cross-court and …

Crisis In The Coalfields: State/Corporate Violence, Historical Trauma, & Concentrated Substance Misuse And Harm, Brooke Baker

Sociology & Criminal Justice Theses & Dissertations

What we frame as "the problem" in our society shapes our responses, which also shapes how and where we spend our resources. The prevailing narratives surrounding drug issues in rural coalfields, West Virginia, the Appalachian region, and arguably throughout the U.S. often mischaracterize the problem. This research explored the relationship between state/corporate violence, historical trauma, and concentrated substance misuse and harm in the rural, central Appalachian coalfields. This study employs a trauma-informed, critical ethnographic approach by utilizing participant observation and photo-elicitation interviewing to collect the data, and a critical qualitative framework to analyze it. The main findings of this research …

What's The Cost?: A Phenomenological Study Of Black Male Teachers' Persistence, Kendra Yvonne Hall

Educational Leadership & Workforce Development Theses & Dissertations

Black male teachers comprise 2% of the teacher population in the United States. In light of this disparity, there is a need to diversify the teacher workforce by recruiting and retaining Black male teachers. Black teachers are influential in students’ academic performance and personal growth. Without their presence, we are missing a key demographic and a key part of a student's educational experience. While Black male teachers’ experiences have been studied, we are less clear on the motivational processes behind their decision to teach. Therefore, this qualitative study takes a phenomenological approach to understand the lived experiences of Black male …

An Examination Of The Perceptions Of Campus Safety Among Full-Time Faculty At Virginia Community Colleges, Hailey Ann Hermosa

Educational Leadership & Workforce Development Theses & Dissertations

The view that colleges are generally safe has been challenged by threats of violence on campuses across the country, causing fear among stakeholders. Community college faculty are not immune to crime-related fear on campus; however, the research has largely ignored this population. This research serves to fill that gap.

The purpose of this nonexperimental quantitative study was to examine perceptions of campus safety among full-time faculty at Virginia community colleges. An electronic Likert-type scale survey was disseminated to a sample of 472 full-time faculty throughout seven Virginia community colleges of varying sizes. Of those, 135 (28.7%) voluntarily participated in the …

Surfacing Text Changes In Archived Webpages, Lesley Frew

Computer Science Theses & Dissertations

Webpages change over time, and web archives hold copies of historical versions of webpages. Users of web archives, such as journalists, want to find and view changes on webpages over time. However, the current search interfaces for web archives do not adequately support this task. For the web archives that include a full-text search feature, multiple versions of the same webpage that match the search query are shown individually without enumerating changes, or are grouped together in a way that hides changes. We present a change text search engine that allows users to find changes in webpages. We describe the …

Study Of Atypical Alarmone Synthesis In Clostridioides Difficile, Declan Nathaniel Butler

Chemistry & Biochemistry Theses & Dissertations

Clostridioides difficile is a Gram-positive anaerobic bacterium that causes infections in humans that costs healthcare systems billions per year. C. difficile infection has high rates of recurrence due to multiple antibiotic resistance. When bacteria are in stressful environments, they produce hyperphosphorylated guanosine ribonucleotide signaling molecules called alarmones. The accumulation of alarmones activates the stringent response (SR), in which bacterial cells induce transcription of stress survival genes to delay growth and replication. The C. difficile SR is regulated by enzymatic activity of a bifunctional synthetase/hydrolase, RelA/SpoT homolog (RSH), and a monofunctional small alarmone synthetase (RelQ). Additionally, the SR is potentially regulated …

Gender Measurement Invariance Of The Minnesota Multiphasic Personality Inventory - Adolescent - Restructured Form (Mmpi-A-Rf) Internalizing And Externalizing Specific Problem Scales, Thomas Jay Augustin

Psychology Theses & Dissertations

Due to social, psychological, biological, and cultural differences in adolescent development, it is important to evaluate measurement invariance in psychological measures. Although the Minnesota Multiphasic Personality Inventory (MMPI) assessments have a plethora of research to evaluate their utility in clinical practice, few published studies have examined the measurement invariance between males and females for any of the scales in the adolescent versions (MMPI-A/MMPI-A-RF). The present study examined the measurement invariance of the MMPI-A-RF Internalizing and Externalizing Specific Problem Scales between male and female adolescents. Data were obtained from an outpatient sample and from Pearson’s mail-in service resulting in 1,622 valid …

Body Image Dissatisfaction, Positive Body Image, And Health Behaviors During Pregnancy: A Between-Trimester Comparison, Cassidy M. Sandoval

Psychology Theses & Dissertations

Body image during pregnancy is a critical concern for maternal and fetal health, as it is associated with adverse health outcomes for mothers and neonates. Findings regarding if and how body image dissatisfaction changes during pregnancy are equivocal. A vast majority of studies examining body image during pregnancy focus on negative aspects of body image (e.g., body dissatisfaction), and there are limited studies of positive body image during pregnancy. Although the literature examining body image’s association with mental health concerns during pregnancy is well-developed, there is far less research exploring associations with physical health. Given these notable gaps, the present …

“[T]He Observance Of Trifles": Mapping Imperial Assemblages In Nineteenth-Century British Serialized Crime Fiction, Dana Joy Gavin

English Theses & Dissertations

This project investigates representations of the ecological and Imperialist relationships in a selection of serialized crime fiction texts: Mary Elizabeth Braddon’s Lady Audley’s Secret, Wilkie Collins’ The Moonstone, and Arthur Conan Doyle’s Sherlock Holmes adventures (appearing in The Strand Magazine: An Illustrated Monthly beginning in 1891). I examine serialized crime fiction published in the nineteenth century as a map of the ecological and Imperialist relationships established through the nineteenth-century British publishing industry. Serialized crime fiction was both popular and profitable, representing not only commercial success but one that tapped into the reading populace’s imagination. Readers craved serialized stories …

Raemap: Real-Time Advanced Eye Movements Analysis Pipeline, Gavindya Jayawardena

Computer Science Theses & Dissertations

Eye-tracking offers insights into human cognition and attention allocation by capturing and interpreting eye movements. Traditionally, eye tracking research has relied on offline analysis methods, requiring post-experiment processing to derive insights from gaze data. This approach limits its applicability in contexts requiring immediate feedback and adaptive responses based on real-time gaze behaviors. Recent advancements in computing power and eye tracking technology have enabled a shift towards real-time analysis, allowing modern systems to interpret gaze data with minimal latency, facilitating integration into interactive applications and experiments. Despite these advancements, existing tools often face challenges with real-time computation of advanced gaze measures …

Tracing The Development Of Trust In Automation/Autonomy In A Multitasking Environment, Tetsuya Sato

Psychology Theses & Dissertations

Future Advanced Air Mobility (AAM) operations will likely involve autonomous systems that exceed the capabilities of a typical automation. However, human operators could use such systems counterproductively by either misusing unreliable systems or disusing reliable systems. One determinant for inappropriate use of autonomous systems is trust. Human factors theorists proposed numerous ways to characterize trust such as the tripartite model of trust that describes the bases of trust in automation (i.e., performance, process, and purpose; Lee & See, 2004). Previous works have indicated that participants rated lower performance- and process-based trust toward the automation when the tracking task required more …

A Smartphone-Based Cardiac Health Monitoring System For Hypertension, Kazi Shafiul Alam

Dissertations (1934 -)

Hypertension is the primary modifiable risk factor affecting global health across all causes. It is responsible for developing serious health concerns, including Cardiovascular diseases (CVD), the number one cause of death worldwide. More than half of individuals with hypertension do not know about their condition, and a substantial portion of those who are aware do not get the appropriate treatment. However, effectively managing hypertension has the potential to reduce the global burden of disease and mortality. Monitoring hypertension and cardiovascular health at home or in the office often requires specialized equipment or wearable devices, which can be uncomfortable, require specific …

Animal To Human Scaling Of Cervical Spine Injury Tolerance In Frontal Impact, Jesse William Gerringer

Dissertations (1934 -)

Cervical spine (c-spine) injury tolerance is not well understood during severe frontal impacts. While these c-spine injuries are rare, they are disproportionally debilitating to the individual in the long term. To study the dynamics of c-spine injury during frontal impact, this dissertation repurposed historical kinematic data from frontal impact experiments using a modern statistical and modeling approach. Frontal impact data was obtained from two historic sources: non-human primate (NHP) experiments from the Naval Biodynamics Laboratory and human research volunteer (HRV) experiments from the Air Force Research Laboratory. First, injury probability curves were calculated from published NHP peak head kinematics and …

Understanding Foster Parents' Experiences Of Secondary Traumatic Stress, Sarah Marie Boeding

Dissertations (1934 -)

Secondary traumatic stress, which has been studied across many helping professions, refers to symptoms similar to posttraumatic stress disorder which an individual may develop as a result of indirect exposure to another individual’s trauma (Sprang et al., 2019). Foster parents may be particularly susceptible to developing secondary traumatic stress due to their exposure to their foster child’s trauma history and trauma symptoms, which has been confirmed in recent studies (Bridger et al., 2020; Whitt-Woosley et al., 2020). Importantly, foster parents’ experiences of secondary traumatic stress may differ from those of other helping professionals given their unique role. The purpose of …

Novel State Estimation Techniques And Their Applications, Jiayi Su

Dissertations (1934 -)

This dissertation contributes to the field by developing and applying novel state estimation techniques in three distinct areas: the detection of cyber-physical systems (CPS) intrusion, the estimation of State-of-Charge (SOC) and State-of-Health (SOH), and multi-object tracking in video sequences. In the first area, emphasis is placed on the detection of unknown intrusion signals within CPS. A pioneering detection scheme is formulated to discern potential cyber-attacks on industrial control systems. A novel intrusion model is first introduced and subsequently incorporated into the Multi-Model Adaptive Estimation (MMAE) technique for the identification of sensor or actuator attack signals. Simulation results underscore the effectiveness …

Mechanisms Of Fatigability In Individuals With Prediabetes And The Effect Of Dietary Nitrate Supplementation, Blaine Evan Arney

Dissertations (1934 -)

Prediabetes is characterized as elevated blood glucose levels below the clinical threshold for type 2 diabetes. Previous research identified an increased fatigability (exercise-induced reduction in limb force or power) of the lower limb muscles in individuals with prediabetes which can impair physical function and lead to reduced physical activity. The mechanisms of fatigability in people with prediabetes are not known but are likely related to suggested vascular dysfunction in prediabetes. An important healthcare goal is to determine effective treatments to offset the increased fatigability in people with prediabetes to improve daily function. The purpose of this dissertation was to determine …

African American Women’S Writing: A Critical Edition Of A Narrative Of The Life And Travels Of Mrs. Nancy Prince (1856), Susan E. Landwer

Dissertations (1934 -)

This dissertation expands on current knowledge of how Black women of the early nineteenth century not only participated in political and social movements within the United States but were instrumental in effecting fundamental social and economic progress both domestically and abroad. They did this while grappling with what their US citizenship meant to them within a gendered and race-based hierarchy. In the process, they had their own labor to sustain their livelihood and apprenticed the future labor of others. Centering on Nancy Gardner Prince (1799-1859), a Black activist born in Newburyport, Massachusetts, I explore how Prince was not an exception …

Regularized Multivariate Functional Principal Component Analysis, Yue Zhao

Dissertations (1934 -)

Multivariate Functional Principal Component Analysis (MFPCA) is a valuable tool for exploring relationships and identifying shared patterns of variation in multivariate functional data. However, interpreting these functional principal components (PCs) can sometimes be challenging due to issues such as roughness and sparsity. In this dissertation, we establish the theoretical foundations of the penalized MFPCA problem within Hilbert space and propose three novel regularized MFPCA approaches. These approaches utilize eigen decomposition and singular value decomposition (SVD) techniques to enhance the performance of MFPCA by incorporating multiple penalty terms, such as roughness and sparsity penalties. In the first method, a roughness penalty …

Designing And Optimizing Hybrid-Pm Variable Flux Machines, Hesham Saeed Badahdah

Dissertations (1934 -)

Research interest in variable flux machines has been steadily growing in recent years. Permanent magnet machines provide a high-power density and efficiency across the entire speed-torque curve. However, this type of machine experiences a drop in efficiency as it transitions into the high-speed region. On the other hand, eliminating the rare-earth permanent magnet used in the variable flux machine is increasingly garnering interest among researchers, especially in traction applications. The interest in this field is due to the scarcity of rare-earth magnets because of the limited availability of the elements necessary to produce these magnets, and because they originate predominantly …

Precision Deuteration And Hydrofunctionalization Of Aryl Alkynes And Alkenes, Samantha E. Sloane

Dissertations (1934 -)

The similar nature of the hydrogen atom to its isotope, deuterium, allows for the simple exchange of hydrogen atoms for deuterium atoms in drug molecules to alter the absorption, distribution, metabolism, and excretion properties. Installing the deuterium functionality into a specific site in the molecule is essential. Selective hydrofunctionalization reactions of alkynes and alkenes using the highly reactive catalytic Cu–H species have been well developed, and synthetic organic chemistry methods to selectively incorporate one or two deuterium atoms into the benzylic site of organic compounds, a key metabolic position, are elusive. A Cu–H catalytic approach offers selectivity and reactivity to …

Faculty Research, Scholarly, and Creative Activity

Introduction: Social workers, the largest group of mental health clinicians in the United States, play a pivotal role in mental health promotion. Despite the importance of sleep for mental health, there is no empirical research on sleep education interventions for social workers. Method: We designed an online sleep health education intervention to equip social work students to promote healthy sleep practices among their clients. An interdisciplinary team of experts devised the 90 min intervention using an empirically supported behavioral change theoretical model (COM-B). The intervention discusses multi-level factors that impact sleep and emphasizes considerations for health disparities in populations commonly …

Persistent Behavior In Solar Energetic Particle Time Series, N V. Sarlis, G Livadiotis, D J. Mccomas, M E. Cuesta, L Y. Khoo, C M S Cohen, D G. Mitchell, Nathan A. Schwadron

Faculty Publications

We investigate the long-term persistence of solar energetic particle (SEP) time series by means of four different methods: Hurst rescaled range R/S analysis, detrended fluctuation analysis, centered moving average analysis, and the fluctuation of natural time under the time reversal method. For these analyses, we use data sets from the Integrated Science Investigation of the Sun instrument suite on board NASA's Parker Solar Probe. Background systematic noise is modeled using cross-correlation analysis between different SEP energy channels and subtracted from the original data. The use of these four methods for deriving the time-series persistence allows us to (i) differentiate between …
