Educational Leadership & Workforce Development Theses & Dissertations

This phenomenological qualitative study investigated the underrepresentation of women and racially marginalized individuals in the superintendent position, the highest leadership position within K-12 public education. The superintendent position has been overwhelmingly represented by males, even though women were the majority of the teaching workforce. Grounded by institutional theory and viewed through a phenomenological lens, I examined how organizational norms, hiring practices, and access to mentorship contributed to and upheld systemic barriers to the superintendent position. Through exploring the interpreted lived experiences of current female superintendents across public school districts that reflected the national patterns, this research addressed the disparities in …

Graduate Physical Therapy Students Perceived Benefit Of Prior Anatomy Experiences Following Their First Semester Graduate Physical Therapy Anatomy Course, Austin Alexander

EVMS School of Health Professions Theses & Dissertations

Human anatomy stands as a cornerstone prerequisite for admission into graduate-level Physical Therapy Programs. As such, prior anatomy experiences need to prepare students for success in graduate-level coursework. However, studies have demonstrated that undergraduate anatomy courses vary in their ability to predict success in graduate Physical Therapy anatomy coursework. This research aimed to utilize students' perceptions of their undergraduate anatomy experiences to predict grades in graduate-level Physical Therapy anatomy coursework. The multinomial logistic regression in this study revealed that the absence of perceived preparedness was a significant predictor of membership in the C graduate anatomy grade group. Students who did …

Research To Practice Gap: Impact Of Principal Perceptions & Communication On Change Initiatives, Jennifer Sagendorf

Educational Leadership & Workforce Development Theses & Dissertations

The purpose of this study is to examine the experiences, perceptions, and practices of school principals related to evidence-based change initiatives and the continued divide between the findings of educational researchers and the use of these findings by school practitioners. Since the prevalent dichotomy of theory and practice is detrimental to school improvement efforts, it is important to examine the underlying values and beliefs that contribute to perpetuating this divide. For this qualitative phenomenological study, semi-structured interviews with seven elementary school principals provided first-hand accounts of the principals' lived experiences. Through an iterative process of coding, clustering, and cross-case analysis, …

Metamorphosis: An Original Jazz Guitar Concerto Exploring Improvisation And Polystylistic Strategies In The Modern Concerto, Ronnie J. Whitt

Electronic Theses and Dissertations

The electric guitar is underutilized in large ensemble art music. Some composers have sought to alleviate this deficiency by expanding the literature through the electric guitar concerto. Few electric guitar concerti are written for improvised jazz guitar, therefore presenting a need for this research. In this thesis, I explore the development of the jazz guitar concerto and nine compositional strategies that benefit composers writing a multi-genre jazz guitar concerto. I analyze selected jazz guitar concerti through lenses, including phrase-level compositional devices, textural and timbral schema, and musical hybridity, to identify these strategies. These concerti include: D.J. Sparr’s Katrina, Jake …

“Starlight Suite”: A Compositional Exploration Of The Argo Navis Constellations In Three Movements, Adam Miller

Electronic Theses and Dissertations

This thesis explores a compositional technique in which stellar constellations are arranged upon musical staves in a variety of iterations to create a basis from which to draw melodic, harmonic, and rhythmic material. These raw extrapolations of unaltered notes are then arranged and orchestrated into thematic music for full orchestra, centered around elements from the mythological background behind the constellations used. An accompanying analysis explains the specific applications of this technique within each movement of the work, the significance of each, and the variety of ways in which musical inspiration was drawn from the raw materials. The objective of this …

Fusobacterium nucleatum (Fn) is commonly enriched in colorectal cancer (CRC) and associated with poor outcomes, though its mechanisms remain unclear. Our study investigated how Fn affects the tumor microenvironment through single-cell transcriptomic analyses of 42 CRC patient tissues, comparing Fn-positive and Fn-negative tumors. We discovered that Fn impairs IgA plasma cell development and secretory IgA (sIgA) production by disrupting communication with tumor-associated macrophages. Additional experiments in germ-free mice, together with our re-analysis of a publicly available single-cell RNA-seq data set from a CRC mouse model with an intact gut microbiome–both models having been orally gavaged with Fn–jointly validated the causal …

Processing-Driven Crystallization, Morphology, And Mechanics In Pekk Composites, Nicholas Ryan Enos

Dissertations

This dissertation aims to understand how thermoplastic composites can be processed at faster manufacturing rates while identifying how processing variables influence crystallization, morphology, and mechanical properties. Throughout this dissertation, the influence of nano-scale additives, carbon fibers, rapid cooling, shear, and molecular weight on polymer physics, crystallization, morphology, and mechanics is investigated.

The inclusion of carbon nanotubes and graphene nanoplatelets accelerated crystallization, increased nucleation density, reduced lamellar thickness, and shifted governing Hoffman-Lauritzen growth regimes in PEKK. Velisaris-Seferis modelling identified a surface-induced nucleation mechanism in PEKK nanocomposites, and fast scanning calorimetry allowed for the study of rapid cooling rates, helping to identify …

Auction Consensus Algorithm With Loss Mechanism For Decentralized Task Allocation, Jose Rodriguez, Wenjie Dong, Constantine Tarawneh, Qi Lu

Electrical and Computer Engineering Faculty Publications

This paper presents an Auction-Consensus Algorithm with a Loss Mechanism (ACALM), a decentralized task allocation method for multi-robot systems that enhances the existing Consensus-Based Auction Algorithm (CBAA) by incorporating a novel loss propagation mechanism. In contrast to purely greedy bidding strategies, it enables agents to dynamically update task priorities based on the accumulated loss from previously unsuccessful bids. This extended work reduces globally inefficient allocations caused by early suboptimal decisions. The proposed approach is evaluated through large-scale simulations in thousands of randomized scenarios and swarm sizes ranging from 5 to 120 robots. Compared to existing CBAA and GCAA algorithms, ACALM …

Acculturation, Values, And Acculturative Stress For Autistic Latino Emerging Adults And Spanish-Speaking Parents Participating In The ¡Iniciando! La Adultez Program, Antonio F Pagán, Miriam Ortiz, Erin Bernal, Katherine A Loveland, Ana Esparza, Cecilia Montiel-Nava, Ron Acierno

Faculty, Staff and Student Publications

Latino families with emerging adults diagnosed with Autism Spectrum Disorder (ASD) face unique challenges during the transition to adulthood, influenced by cultural values, acculturation, and systemic barriers. Acculturation and acculturative stress are particularly relevant in this population, as they navigate cultural adaptation while maintaining traditional values like familismo (family) and respeto (respect). These dynamics are further complicated by disparities in access to resources and culturally responsive interventions. This study explores the interplay of cultural values, acculturation, and acculturative stress among Latino emerging adults with ASD and their Spanish-speaking parents participating in a culturally adapted and translated intervention. Using a cross-sectional …

Research outputs 2022 to 2026

Food security(FS) refers to having sufficient physical, social, and economic food access at all times. People living in rural, regional, and remote (RRR) locations often face distinctive challenges to FS. Existing solutions, that aim to enhance FS, themselves face challenges when addressing these issues. This paper outlines the application of an adapted Systemic Innovation Lab (SIL) approach to enhance the function of existing community and government-led, -run or -operated initiatives (programs, interventions) in RRR Western Australia. It examines which systems change characteristics participating initiatives possess, to identify opportunities to support their transition to newer and more effective ways of addressing …

Midwife-Led Birth Debrief: A Concept Analysis, Kate Buchanan, Elliesha O'Reilly, Georgia Wilcox, Sara Bayes, Lauren Kearney, Linda Sweet, Hazel Keedle

Research outputs 2022 to 2026

Background: Psychological birth trauma (PBT) affects approximately 19 % of postnatal women, making its prevention a global priority. Midwives are responsible for providing psychosocial care during the postnatal period to foster the mother-infant relationship, provide education and screening and support positive transitions to parenting. However, the specific attributes of a birth debrief and the role of the midwife in a supporting a woman to review their birth experience is less well documented in regulatory frameworks or scientific literature. This has created significant ambiguity in both clinical practice among health professionals and in research contexts. The lack of a clear understanding …

Next-Generation Underwater Localization: Artificial Intelligence-Based And Energy-Aware Approaches, Mainul Islam Chowdhury, Quoc Viet Phung, Iftekhar Ahmed, Walid K. Hasan, Daryoush Habibi

Research outputs 2022 to 2026

Designing accurate, reliable, and energy-efficient localization techniques for underwater acoustic networks is highly challenging due to factors such as large propagation delays, the absence of Global Positioning System (GPS), node mobility, and limited acoustic link capacity. In any underwater sensor network (UWSN) monitoring application, data collected by underwater nodes becomes more meaningful when accompanied by location information. However, traditional localization methods often rely on geometric models and statistical filters that are highly sensitive to sensor noise and communication constraints. Energy consumption is another primary concern in UWSNs, not only because replacing and recharging underwater batteries are challenging, but also due …

Research outputs 2022 to 2026

In the digital age, skilful computer-based writing is essential for school aged children since it empowers them to communicate, acquire knowledge, critically engage with information, and produce text-based original thoughts. However, there is a lack of studies examining teachers’ preparation and self-efficacy for supporting students in developing computer-based writing skills and instructional practices implemented in primary classrooms. In the current study, 340 primary teachers (Grades 1–6) from across Australian states completed a survey about the computer-based writing instruction provided in their classrooms. While results showed that teachers found it was important to teach computer-based writing skills, most respondents reported allocating …

Determinants Of Consumers' Mobile Network Continuance Intention: The Mediating Effects Of Cognitive And Affective Inertia, Fazlul Hoque, Pi Shen Seet, Stephanie Meek, Saalem Sadeque

Research outputs 2022 to 2026

Despite extensive research on customer continuance intention, few studies have explored the mediating roles of cognitive and affective inertia in shaping continuance intention, particularly in emerging markets. We address this gap in an empirical study, grounded in the SOR (Stimulus-Organism-Response) framework, that investigates how trust, satisfaction, and switching barriers influence mobile network users' continuance intention, with cognitive and affective inertia as mediators. Using Partial Least Squares Structural Equation Modelling (PLS-SEM), we analyzed primary data from 407 mobile phone users in Bangladesh, an emerging economy. The findings indicate that trust, satisfaction, and switching barriers have a significant influence on continuance intention. …

Lavery, Albert Pessarodona, Carlose M. Duarte, Oscar Serrano

Research outputs 2022 to 2026

Seagrass meadows play a key role in the global carbon cycle through storing carbon in their biomass and soils. However, the lack of global assessments of carbon stocks in seagrass biomass and net primary production (NPP) limits our understanding of their role in the carbon cycle. Here, we provide global estimates of biomass carbon stocks and NPP encompassing seagrasses with different life-history strategies, across bioregions and 66 countries. Seagrass meadows show up to 800-fold differences in biomass across different life-history strategies and bioregions (mean ± SE; 1551 ± 40 kg C ha⁻¹), whereas seagrass NPP (5833 ± 557 …

Looking At The Nose: Gender, Jewishness, And The Politics Of Visual Mediation, Laura Glitsos

Research outputs 2022 to 2026

The nose is a multisensory organ and a powerful bodily technology that helps orient the experience of consciousness in the material world, and yet, we have come to a socio-technological context so driven by ocularcentrism, largely as a result of the visual nature of social media and new media, that the nose is often reduced to just an idealised ‘shape’. This article explores how the contemporary construction and representation of the nose, especially on social media, is seated in a very long history of gendered and racialised politics. By examining the cultural and political implications of the nose through critical …

Estimation Of 3d Facial Dynamics With Nonlinear Filters For Position Tracking, Thoa Thieu, Roderick Melnik

School of Mathematical & Statistical Sciences Faculty Publications

This study presents a comparative evaluation of three nonlinear state estimation filters, the Extended Kalman Filter (EKF), Unscented Kalman Filter (UKF), and Particle Filter (PF), for the task of 3D facial landmark tracking. Using a publicly available dataset, we assess each filter's performance under both deterministic (noise-free) and stochastic (noisy) conditions. Metrics such as mean squared error (MSE), convergence rates of state and covariance estimates, and consistency over time are used to quantify tracking performance. Results show that the EKF consistently outperforms the UKF and PF, achieving faster convergence and lower estimation error, particularly in scenarios characterized by mild nonlinearity. …

Is Noise Exposure Associated With Impaired Extended High Frequency Hearing Despite A Normal Audiogram? A Systematic Review And Meta-Analysis, Sajana Aryal, Monica Trevino, Hansapani Rodrigo, Srikanta K. Mishra

School of Mathematical & Statistical Sciences Faculty Publications

Understanding the initial signature of noise-induced auditory damage remains a significant priority. Animal models suggest the cochlear base is particularly vulnerable to noise, raising the possibility that early-stage noise exposure could be linked to basal cochlear dysfunction, even when thresholds at 0.25-8 kHz are normal. To investigate this in humans, we conducted a meta-analysis following a systematic review, examining the association between noise exposure and hearing in frequencies from 9 to 20 kHz as a marker for basal cochlear dysfunction. Systematic review and meta-analysis followed PRISMA guidelines and the PICOS framework. Studies on noise exposure and hearing in the 9 …

Using Political Privilege To Profit: Insider Trading In The Government And S. 2463'S Alleged Attempt To Stop It, Allison K. Dooling

MC Law Review

Insider trading is generally illegal within the United States. However, members of Congress are notorious for regularly engaging in stock trades based on government information that mirrors insider trading. In 2023, Senators Gillibrand and Hawley proposed a bill, unlike any such proposed before, to put an ultimate ban on government insider trading: the “Ban Stock Trading for Government Officials Act” or S. 2463. On its face, S. 2463 appears to address the criticisms surrounding government insider trading. It not only increases regulation and reporting standards but also bans government officials, their spouses, and their dependents from owning any stock during …
