Does Short-Termism Pay? National Short-Termism, Investment, Innovation, And Equity Returns, Andrew H. Cohen

Theses and Dissertations in Business Administration

We examine whether national short-termism, inferred from corporate language, predicts future real activity, equity returns, risk, and risk-adjusted performance. Using large-scale textual analysis of issuer-linked disclosures and earnings transcripts from the largest firms in twenty major equity markets, we construct country-quarter and annual Short-Termism Scores (STS) capturing the relative emphasis on short- versus long-horizon language.

Higher short-termism predicts lower subsequent gross fixed capital formation, lower research and development intensity, and lower multi-year equity index returns across horizons of up to sixteen quarters. In addition, higher short-termism is associated with greater future market volatility and lower Sharpe ratios, indicating a deterioration …

An Integrated Bayesian Network-Based Zero Trust Model To Quantify Cyber Risk In Small-Medium Businesses, Ahmed Abdelmagid

Engineering Management & Systems Engineering Theses & Dissertations

Small-medium businesses (SMBs) play a pivotal role in the worldwide economy as they constitute the most considerable portion of businesses in developed countries like the UK and the US. As such, SMBs are likely targets of cybercrimes by malicious agents because of their vulnerable IT systems. The digital infrastructure of SMBs is more likely to be hit by cyberattacks than large businesses due to many factors that facilitate hackers’ missions. These factors include a limited financial budget devoted to cybersecurity, a lack of knowledge, an underrating of how dangerous cyber threats are, and a shortage of IT expertise. The enormous …

The War Poetry Map Project: Exploring The Physical And Emotional Geography Of Conflict, Colin D. Halloran

English Theses & Dissertations

There can be no question that war is shaped by and has shaped cultures, and yet as an object of study it is rarely looked at from a cultural studies perspective. It is the great epics of war that form the cornerstones of Western literary tradition. It is the impact of war that gave rise to fields like trauma and memory studies. It is the propaganda produced, the hijacking of cultural industries, that help perpetuate wars. The War Poetry Map Project and accompanying written dissertation seek to move beyond historical and political contexts and view war as a cultural object. …

Shadowrunning The Human: Harebrained Schemes' Shadowrun Series And Transhumanism, Alexander P. Orelup

English Theses & Dissertations

I argue that Harebrained Schemes’ video game series Shadowrun critiques transhumanism in three distinct yet related ways: in terms of religion, political control, and identity capitalism. In doing so, Shadowrun attempts to counter claims that video games are an inherently transhumanist medium and provides an opportunity for players to resist a potential transhuman future. This further elucidates the trends and perceptions of transhumanism within American culture around the time period. I utilize a variety of methodologies in my argument, ranging from cultural studies, narratology, ludology, and close reading in order to grasp all of the audio-visual and gameplay elements that …

Women's Displacement And The Reclamation Of Identity: Navigating Landscapes Of Contestation In The Postcolonial Novel, Carol P. Harvest

English Theses & Dissertations

Landscapes affected by colonial domination are contested landscapes—places not only in danger of environmental destruction through colonial and neocolonial violence but also landscapes of struggle for people who survive in these precarious spaces. Historically, separate postcolonial and ecocritical literary analysis addressed contested landscapes; postcolonial critique centered on the lasting devastation of colonial violence on people and place, while ecocriticism, in its infancy, enjoyed the privilege of ignorance, focusing on endangered species and the preservation of land, but it did not consider the impact of landscapes on the very people who were largely forced to either leave or cross “natural” spaces. …

The Physiology Of The Work: Chronic Stress, Allostatic Load, And Faculty Wellness In Counselor Education, Ajayla S. Evins

Counseling & Human Services Theses & Dissertations

Counselor educators embody multifaceted professional roles across teaching, supervision, research, leadership, and service, exerting a profound influence on the formation of counselors and the ongoing development of the profession (CACREP, 2024; Calley & Hawley, 2008). While wellness is recognized as a core professional value in counseling (ACA, 2014), research has focused almost exclusively on emotional and psychological dimensions, leaving the physiological consequences of chronic stress largely underexplored (Bovee, 2024; Faheem et al., 2025; Lewis et al., 2022). In neighboring fields, such as public health and medicine, chronic stress has been linked to dysregulation in cardiovascular, neuroendocrine, immune inflammatory, and metabolic …

The Effects Of Covid 19 Job Demands On Public Sector Employees’ Organizational Commitment: The Mediating Roles Of Work Engagement And Job Burnout, And The Moderating Role Of Supervisor Support, Benjamin R. Kaufman

Psychology Theses & Dissertations

United States citizens rely on state government employees to provide essential public services. During the COVID-19 pandemic, these employees responded by administering both routine and novel procedures to protect public health, often placing them on the frontlines and at increased risk of contagion. Concurrently, the pandemic-driven economic downturn created budget shortfalls that threatened the job and financial security of the state workforce. Together, these conditions substantially increased job demands for state government employees.

Guided by the Job Demands–Resources (JDR) Model, this study examined how COVID‑19-related job demands influenced state employees’ work engagement, job burnout, and organizational commitment, and whether supervisor …

Cavitation-Aware Design Of Hydrofoil Sections For Marine Propeller Blade Development, Samuel G. Bacon

Mechanical & Aerospace Engineering Theses & Dissertations

Cavitation is a major design constraint for marine propeller blade sections because it can reduce hydrodynamic performance, increase vibration and noise, and contribute to surface damage. This thesis develops and applies an exploratory computational framework for cavitation-aware hydrofoil-section design relevant to marine propeller blade development. The framework combines section-level CFD validation, CST-based geometry parameterization, pressure-based pre-screening, matched-load comparison, and focused predicted inception envelope or cavitation-bucket analysis.

The CFD methodology was validated against published YS-920 hydrofoil water-tunnel data using selected fully wetted, near-inception, and cavitating reference cases. The validation results showed that the adopted framework reproduced the key experimental trends needed …

Empowering Change: Building Environmental Sustainability Initiatives And Becoming A Sustainability Champion, Amanda C. Karls

School of Public Service Theses & Dissertations

In an era marked by escalating environmental challenges and an urgent need for sustainable development, higher education institutions (HEIs) are increasingly positioned as critical actors in advancing sustainability within the communities they serve. Regional comprehensive universities (RCUs), in particular, occupy a distinctive position as access‑oriented, community‑embedded public institutions; yet sustainability efforts at these institutions often unfold under conditions of limited resources, diffuse responsibility, and informal governance. This dissertation examines how individual actors at RCUs effectively advance environmental sustainability initiatives in the absence of centralized infrastructure or formal authority.

Guided by the overarching research question—How can individual actors at regional comprehensive …

Perceptions Of Virginia Dentists And Dental Hygienists Towards Emerging Alternative Dental Hygiene Workforce Provider Models, Lauren B. Mangum

Dental Hygiene Theses & Dissertations

Background: A perceived shortage of dental hygienists in the United States has been linked to delays in preventive care and concerns about declining oral health outcomes. In response, some states have proposed alternative pathways permitting internationally trained dentists, dental students, and oral preventive assistants (OPAs) with limited or inconsistent education requirements to provide dental hygiene services. Limited evidence exists regarding whether these strategies would effectively address access to care and workforce challenges. Concerns have also been raised about the potential effects of expanding scope of practice for providers with limited education or training on patient safety and quality of care. …

Ultra-High Vacuum Outgassing Characterization Of Thermally Processed Low-Carbon Steel For Advanced Particle Accelerator And Gravitational Wave Detector Applications, Aiman H. Al-Allaq

Mechanical & Aerospace Engineering Theses & Dissertations

This dissertation investigated AISI 1020 low-carbon steel as an alternative vacuum chamber material to conventional stainless steel for ultra-high vacuum (UHV) and extreme-high vacuum (XHV) applications. After a 400 °C/48 h bake, AISI 1020 tube chambers achieved a hydrogen outgassing rate of 2.4 × 10⁻¹⁶ Torr·L·s⁻¹·cm⁻², approximately 2,300 times lower than the prebaked 316L stainless-steel comparator, among the lowest hydrogen outgassing rates ever reported for an uncoated metallic vacuum chamber. Bare and magnetite-coated AISI 1020 chambers were then compared using throughput and rate-of-rise methods. The magnetite coating yielded 5× lower water outgassing at room temperature, but this advantage disappeared after …

Dissecting The Etiology Of Alcohol Use Disorder By An Integrative Heritable Component Approach, Ivy Garrenton

Computer Science Theses & Dissertations

Alcohol Use Disorder (AUD) is a pervasive condition characterized by complex interplay among genetic, phenotypic, and environmental factors. Although previous studies have identi fied genetic loci associated with alcohol consumption, these efforts have not captured the genetic heterogeneity and gene-environment interactions underlying AUD pathogenesis. To address this critical gap, we developed a novel statistical methodology that integrates phenotypic, genotypic, and environmental data through an environmentally modified Genetic Relationship Matrix (GRM) to derive AUD-related traits with enhanced heritability.

This approach demonstrated superior performance in both simulated and real-world datasets. Traits derived using the environmentally modified GRM exhibited significantly higher estimated heritability …

Student Perceptions Of The Community Of Inquiry In Online Human Anatomy And Physiology Discussion Boards Using 2-D And 3-D Anatomical Models, Timothy J. Mcguire

EVMS School of Health Professions Theses & Dissertations

Online human anatomy and physiology (HA&P) courses require students to learn complex anatomical content outside of a physical laboratory environment, a challenge that may be supported by enhancing students’ perceptions of collaborative learning (CL) through the community of inquiry (CoI) framework. This convergent parallel mixed-methods study examined participants’ perceptions of the CoI framework during two discussion board (DB) activities in an online, asynchronous, noncredit HA&P I study course at a midwestern community college.

Participants were recruited via convenience sampling and randomly assigned to one of two instructional sequence groups (2-D→3-D or 3-D→2-D) to complete two DB activities requiring annotation of …

Norfolk Flooding And Its Effect On Nutrient And Enterococcus Levels, Malachi R. Stephens

Knowledge and Creativity Expo

Tidal flooding is common in the City of Norfolk, VA due to high rates of sea rise in the region, as well as the region’s subsidence. This has led to increases in flooding at high tide, especially during the spring tide portion of the tidal cycle.  At high tide water from the Elizabeth and Lafayette Rivers can flood the landscape directly or can rise out of storm drains. This floodwater often stays on land for long periods of time and can deliver contaminants back into the rivers. To determine the amounts of nutrients and Enterococcus, a fecal indicator, delivered to …

Examining The Relationship Between A Positive Obstructive Sleep Apnea Diagnosis And Referring Symptoms Of The Pregnant Patient, Christina Emerson, Beth Tremblay

Knowledge and Creativity Expo

PROBLEM: Many healthcare providers do not routinely screen pregnant individuals for obstructive sleep apnea (OSA), contributing to its underdiagnosis and potentially leading to various pregnancy-related health issues. Currently used OSA screening tools, such as the Berlin Questionnaire, STOP-BANG Questionnaire, and Epworth Sleepiness Scale, often demonstrate poor predictive value in pregnant women due to the dynamic physiological changes of pregnancy and the differing presentation of OSA in this population.

PURPOSE: To examine the relationships between a positive OSA diagnosis, patient characteristics, and the symptoms among pregnant patients referred for sleep studies.

EBP QUESTIONS: 1) Is there a relationship between certain referring …

Remediation Of Ammonium Perrhenate Via Tris(2,2’-Bipyridine)Ruthenium(Ii) Chloride, Kaylin L. Thomas, Sandra A. Abdellah, Alvin A. Holder

Knowledge and Creativity Expo

Pertechnetate (TcO₄⁻) is a persistent radioactive byproduct resulting from the decay of uranium-235 or plutonium-239 in the nuclear fuel cycle. Its high environmental mobility, long half-life, and significant beta radiation make TcO₄⁻ a critical contaminant. Structurally tetrahedral and water-soluble, TcO₄⁻ behaves similarly to the sulfate anion, facilitating its rapid introduction into ecosystems.

It bioaccumulates in lower-level organisms, propagating radioactive and toxic effects through food chains. In mammals, technetium-99 accumulates in the thyroid and may also impact fetal development. Its small charge, chemical stability, and solubility present significant challenges for effective remediation.

Current remediation methods often suffer from poor selectivity, dependence …

Reconstructing 5000 Years Of Hurricane Activity In Holyrood Pond Using Sediment Core Analysis, Jamie Mclaulin, Arielle Nogueira, Elizabeth Wallace

Knowledge and Creativity Expo

Hurricanes are hazardous and costly events that annually negatively impact people that live in coastal areas in North America.  The current observational record of hurricanes is short (1970- present) and does not offer insight into the effects of climate change on hurricane frequency.  One method of improving and extending our observational record of hurricanes is to reconstruct paleohurricanes using sediment cores.  These cores record hurricane activity in the form of coarse-grained overwash layers that are deposited when hurricanes move sand from beaches into backbarrier ponds.  In this project, we analyzed sediment cores from Atlantic Canada to locate coarse-grained storm layers …

Methane Consumption Rates By Coastal Virginia Beach Microbes, James R. Bailey Ii

Knowledge and Creativity Expo

This study measures whether microbial communities in the shallow coastal waters of Virginia Beach are capable of consuming methane in the water column. Using methane enrichment incubations and gas chromatography, we found no measurable methane oxidation of our samples over multi-day periods. These results suggest that these coastal waters may act as net sources of atmospheric methane.

Is The Chesapeake Bay Browning?, Samantha Williamson, Jessie Turner

Knowledge and Creativity Expo

Brownification is when water bodies turn brown over time. It occurs due to high amounts of color-dissolved organic matter (CDOM). CDOM is organic material, such as decaying leaves and organisms, that leaches into the water column like tea. It absorbs ultraviolet and blue light more than red light, causing the water to appear brown. After comparing surveys from 1987 and 2018, scientists discovered the Adirondack lakes underwent brownification as they recovered from acid rain. However, while increased CDOM can signify an ecosystem’s recovery, it can also hinder seagrass growth. Although scientists have studied this phenomenon in lakes, estuaries have not …

Living Shorelines As A Solution To Saltwater Marsh Erosion, Elizjah Eddy, Richard Hale

Knowledge and Creativity Expo

In recent years, saltwater marshes fringing the Lafayette River, a tributary of the Elizabeth River, have experienced degradation in response to increased inundation and ocean energy . These marshes provide critical ecological and economic benefits to the City of Norfolk, and prioritizing their long term health and sustainability is an important challenge. An emerging restoration tactic involves enhancing marsh elevation through the application of dredge material that would otherwise require disposal offshore (known as thin-layer placement or TLP). An important first step in TLP projects is characterizing the textural and geochemical properties of the existing marsh sediment. The goal of …

How Much Does Shape Matter: Investigating The Impact Of Marine Particle Morphological Features On In-Situ Settling Velocities Using Pca And Various Ml Models, Huanqing Huang, Alexander B. Bochdansky

Knowledge and Creativity Expo

Particle settling velocity serves as an essential component in ocean biological pump, as it determines particle retention time in the water column. Stokes’ law has been widely used to predict particle settling velocities by particle size and excess density in aquatic environments. However, an increasing number of studies suggest that Stokes’ law fits poorly in the size-velocity relationship of observations on small oceanic particles. Here, we present a series of novel approaches to investigate the relative contribution of settling velocities by the particle shape and optical densities using machine learning (ML) models and principal component analysis (PCA), based on 3906 …

Mitochondrial Transfer And Induced Ros As A Therapeutic Strategy In Idh2-Mutant Chondrosarcoma, Vegas R. Bedder, Caleb Wyckoff, Chris Osgood, Gavin A. Vasquez, Michael Stacey

Knowledge and Creativity Expo

Chondrosarcoma (CS) are common bone cancers that produce cartilaginous tumors and are extremely refractive to chemo-and-radiation therapies, leaving very limited treatment options. They contain mutations in the isocitrate dehydrogenase genes, IDH1 or IDH2. Either IDH1 or IDH2 mutations are present in individual tumors, but not both. They both convert alphaketoglutarate (αKG) into the potent oncometabolite D-2-hydroxyglutarate (D2HG). D2HG can be transported from the tumors to cells of the tumor microenvironment (TME) where it can alter metabolic and epigenetic profiles in recipient cells. The process of α-KG to D2HG conversion occurs in the cytoplasm of IDH1 mutant cells, and in the …

Human Subject Studies For The Alignment Of Llm-As-A-Judge Evaluation Metric For Science News, Gabriel Vega Osborne

Science news has become an important vehicle to disseminate scientific breakthroughs, discoveries, and technological innovations. With the advancement of large language models and related AI models, it is possible to automatically generate science news from scientific papers, extending the reader population from domain scientists to a broader scope. However, how to evaluate the quality of the generated news warrants research. Traditional token based metrics have been shown to fail to evaluate the semantics and nuances of science news. Inspired by the fact that a major goal of science news is to educate readers with new knowledge, we thus propose knowledge …

Optimizing Continuous Renal Replacement Therapy (Crrt) In The Icu: A Qsen-Based Framework For Nursing Decision-Making Support, Leslie Okhirkhian

Knowledge and Creativity Expo

Nurses in critical care environments must exercise precise clinical judgement to recognize patient destabilization cues while managing the complex biomedical technologies that support failing physiological systems. Continuous Renal Replacement Therapy (CRRT) is a modality for hemodynamically unstable patients requiring fluid overload management and waste removal; however, it is a complex technology that demands nurses navigate a “tightrope” between renal perfusion and hemodynamic stability. Despite its prevalence, there is no concise decision-making support for nursing care in the current literature based on the Quality and Safety Education for Nurses (QSEN) strategies. This presentation addresses this gap by proposing a QSEN-based, standardized …

Evaluating Sensory Sensitivities Among Children With Autism Spectrum Disorder In An Adaptive Gymnastics Program, Aicha Kaouss, Bradley Eppinger, Austin Ebbrecht, Kailash Ram, Kaitlin P. Hardy Md

Knowledge and Creativity Expo

Introduction: Children with autism spectrum disorder (ASD) participate in physical activity at lower rates than their neurotypical peers1. Sensory sensitivities, reported in approximately 75–95% of children with ASD, may contribute to this disparity2. Gymnastics environments involve bright lighting and loud noise, which can precipitate sensory overload. The impact of specific sensory features on participation in adaptive gymnastics remains underexplored.

Methods: A cross-sectional study recruited caregivers of children aged 3–12 years with an ASD diagnosis enrolled in the EVMS Adaptive Gymnastics Program. Caregivers completed the Sensory Experiences Questionnaire–Third Edition (SEQ-3)3 and supplemental survey items on Redcap which assessed environmental triggers and …

From Tiktok To Transcendence: Reclaiming Focus Through Contemplative Education, Araceli Gordus Huizar

Knowledge and Creativity Expo

In an era shaped by the attention economy and digital technology, students in higher education navigate constant stimulation that fragments attention, increases stress, and challenges emotional regulation. Research in psychology and neuroscience suggests that chronic exposure to social media, AI tools, and multitasking environments contributes to divided attention and diminished cognitive performance. While institutional responses, such as phone bans, attempt to manage distraction, they often fail to cultivate the internal capacities necessary for sustained focus and meaningful learning.

This paper argues that contemplative education--grounded in Buddhist and Hindu contemplative traditions and informed by humanistic psychology and contemporary mindfulness-based interventions--offers a …

Two Wrestlers: An Unrealized Herculean Pendant To Michelangelo’S David, Theodore Mayberry

Knowledge and Creativity Expo

Following the completion of Michelangelo’s David 1504, Gonfalonier Piero Soderini presented the emerging Florentine artist with a proposal for a second statue on behalf of Florence’s government: a statue of Hercules to stand alongside the David at the entrance of the Palazzo Vecchio. Michelangelo readily accepted, however the commission never came to be; what remains of Michelangelo’s vision for the Herculean pendant now resides in the Casa Buonarroti Museum of Florence: a rough terracotta model of Hercules and Cacus. Upon review of the scholarship documenting Michelangelo’s unrealized Hercules as well as his David, an intriguing pattern can be observed …

Who Feeds On Whom? Identifying Ticks Feeding On Mammal, Brenna G. Albright, Christina Espada, Mykenna Zettle, Abbey Jones, David T. Gauthier, Holly Gaff

Knowledge and Creativity Expo

Study of tick-host association is critical to understanding host-pathogen ecology. Collection of ticks from mammalian hosts is difficult because of permitting, cost, and time considerations, particularly for medium and large mammals. The ODU Tick Research Team has been collecting ticks from mammals since 2010 using a combination of serendipitous sampling from roadkill and donations from veterinarians, hunters, and wildlife rehabilitators. In this work, we quantify the association between Ixodes scapularis and Ixodes keiransi and various mammalian hosts in Virginia. Ixodes scapularis (deer tick or blacklegged tick) is the primary vector of the Lyme disease bacterium (Borrelia burgdorferi s.s.) in …
