A Systematic Review Of The Outcomes And Efficacy Of Complementary And Alternative Non-Pharmacological Interventions In Youth With Attention Deficit Hyperactivity Disorder, Kelly M. Kohler

Theses and Dissertations

A number of behavioral and pharmacological treatments have been widely accepted as evidenced-based approaches to treating symptoms of attention-deficit hyperactivity disorder (ADHD) in children and adolescents. While pharmacological approaches are safe and effective at managing symptoms, a large subset of caregivers do not have access to medication, refuse it, or find it ineffective, necessitating the need for non-pharmacological treatments. Such behavioral interventions are also generally effective approaches to symptom management and reducing the functional impairment of ADHD and may even demonstrate better parent satisfaction than medication alone. However, these interventions are often difficult to access and burdensome to implement, especially …

A diverse group of teachers, varying in experience, age, gender, and race, were interviewed to gather a range of perspectives on the implementation of this curriculum. The study focused on addressing the following research questions: 1. What are teachers’ perceptions of culturally responsive and culturally relevant instruction and academic …

Incarcerated Youth Returning To Society As Adults: An Examination Of Their Lived Experiences And Challenges, Kimberly R. Lawrance

Theses and Dissertations

When children have been incarcerated, they face collateral consequences that make it nearly impossible to recover from when they return home. Collateral consequences are the adverse effects experienced by incarcerated people and their families often causing restrictions or missed opportunities after interaction with the criminal justice system (Moise, Simonsen, & Kearl, 2023). Collateral consequences can be related to housing, employment, and education, to name a few. These lost opportunities are concerning for youth because most have never held a job or finished high school. Collateral consequences often set them up for failure leading to the revolving doors of jails and …

The Diseased Extracellular Matrix In Chronic Obstructive Pulmonary Disease Modeling, Leigh-Ann M. Antczak

Theses and Dissertations

Chronic obstructive pulmonary disease (COPD) is currently the fourth leading cause of death in the world, with an increasing prevalence as the world’s population ages. In the distal regions of the lungs, COPD is characterized by progressive emphysema due to an imbalance of proteases that continuously degrade essential extracellular matrix (ECM) proteins within the alveolar walls, causing fatal tissue impairment. This dissertation examines the unique properties of this diseased lung ECM in two parts: (1) As a key constituent in inflammatory signaling that leads to increased inflammation and progression of COPD, and (2) as a tool in three-dimensional (3D) in …

Wiring Attachment, Alexander K. Bacon

Theses and Dissertations

This thesis began with a question: can diagrams create understanding, or only reflect it? Through paintings that layer automotive wiring schematics with family photographs, I explore how the human attachment system resists easy mapping. Using digital tools like Photoshop and scanning, alongside analog methods such as papier-collé and photo transfer, I examine how systems built for clarity—like wiring diagrams—contrast with the layered, often messy realities of human relationships. Drawing from attachment theory’s empirical foundation, rather than the metaphorical leanings of psychoanalysis, my work investigates how emotional bonds form, falter, and repair over time. Material loss and layering are not flaws, …

The Dance Of Human Affairs: Public Administration Leaders’ Perceptions Of Candor’S Impact On A Sense Of Belonging, Aaron Dimmock

Theses and Dissertations

This dissertation examines public administration leaders’ perceptions within the executive branch of the state government studied to determine if the components of radical candor, care personally and challenge directly, are associated with the sense of belonging in a public administration setting. Questions from surveys conducted by the state government studied were used to create the variables analyzed in this study. To the researcher’s knowledge, this is the first study to apply components from the Radical Candor® Framework to determine a relationship with sense of belonging in a public administration setting.

The significance of these components was tested through a quantitative, …

Identification Of Mechanisms Associated With Electronic Nicotine Delivery System Use For Weight Control In Young Adults, Gabrielle Maldonado

Theses and Dissertations

Electronic nicotine delivery system (ENDS) use continues to rise among young adults in the United States, raising public health concerns as the harmful effects of ENDS continue to rise while tailored cessation programs lag. Weight control motives may drive ENDS initiation and frequent use, particularly among sexual and gender minority (SGM) populations, who report higher ENDS use, body dissatisfaction, and disordered eating behaviors than those who identify as heterosexual and cisgender. Understanding these behaviors, their mechanisms, and at-risk populations is critical for improving public health. Seven hundred and eight young adults (ages 18–30; M = 26, SD = 3.3) reporting …

This flexible system enabled efficient production of both small- and large-particle powders …

Isolating Confounding Abiotic And Biotic Effects On The Phenotype On Physa Acuta Snails, Ashley M. Bauer

Theses and Dissertations

Organisms match their phenotypes to prevailing environmental conditions leading to habitat specific polymorphisms. Polymorphisms arise from genetic divergence, phenotypic plasticity, or a combination of both processes. I examined the presence of habitat-specific polymorphism in Physa acuta snails collected from three streams and their corresponding downstream reservoir. In lotic systems shells were rotund with larger apertures, while those from lentic systems were more elongate with smaller apertures. In a reciprocal transplant lab experiment that crossed flow regime and crayfish predator cues, I tested for the underlying mechanisms responsible for the observed phenotypic differences. I found no evidence for plasticity in relation …

Hillslope Degradation: Coarse Sands May Move Faster But Fines Dominate Flux, Robert Chance

Theses and Dissertations

Hillslopes are one of the most pervasive landforms on Earth yet the details of the processes that drive their evolution are not completely understood. Excluding boulders, the majority of mass and volume in soil-mantled hillslopes is composed of sand-sized and finer grains. Understanding the transport rates and governing transport mechanisms of these grains is therefore key to advancing our knowledge of hillslope evolution.This research investigates sand-sized sediment transport through field experiments at 20 sites tracking surface sediment motion and 11 sites measuring depth-dependent transport. These empirical results are compared against outputs from a novel grain-based hillslope diffusion simulation (GBHDS), which …

An Exploratory Investigation Of The Impact Of Psychological Intimate Partner Violence On College Women: A Qualitative Study, Dana Juel Conzemius-Schindler

Theses and Dissertations

Researchers have found psychological intimate partner violence (P-IPV; defined as emotional and verbal abuse utilized to degrade, demean, create fear, control, or isolate; Tolman, 1989; Sullivan et al., 2012) is detrimental to mental health functioning, including increased sexual risk behaviors, depressive and anxious symptomology, and relationship dissatisfaction (Hellemans et al., 2015; Overstreet et al., 2015). Despite this, little is known regarding the academic and psychological lived experiences of survivors of P-IPV. Therefore, the current study sought to qualitatively explore the lived experiences of female-identified students exposed to psychological intimate partner violence while in college. Through a Consensual Qualitative Research (CQR; …

Polarization And Civil Discourse In America: A Case Study Of Respectful Dialogue As A Moderating Influence On Generation Z, Liane Weintraub

Theses and Dissertations

Animosity between opposing political parties is longstanding, but the phenomenon is now acutely pervasive and dangerous. Today, polarization is further fueled by social media algorithms that create echo chambers, limiting discourse about diverse viewpoints. Consequently, polarization has become pernicious and threatens the founding principles of American democracy. This dissertation considers the roles of free speech, civility, and social capital in the US polarization problem. Through an exploration of historical scholarship on virtue, ethics, and civility, the study seeks to identify actionable tools for promoting civil discourse. The dissertation investigates Generation Z (Gen Z), focusing on intergenerational differences, the role of …

Best Educational Practices For Supporting English Learners During Remote Learning, Dimitrina S. Gotzeva

Theses and Dissertations

Remote learning (RL) has gained significant momentum in recent years, particularly following the COVID-19 pandemic lockdown, underscoring the need for technology to facilitate remote education. Despite its increased prominence, RL has been a long-standing educational tool, enabling students to access quality education even when physically distant from prestigious institutions. However, the effectiveness of RL has been a topic of ongoing debate, with no clear consensus in the literature on the optimal strategies to enhance its outcomes. Focusing on English language learning, this study aimed to investigate the challenges and barriers associated with RL and identify effective strategies to improve its …

Educating Outdoors: A Qualitative Case Study On School Readiness Development In A Nature-Based Preschool, Lauren Lefevre

Theses and Dissertations

Play is widely considered one of the most crucial activities for healthy early childhood development, yet many current early childhood education (ECE) programs prioritize academics at the expense of this critical activity. Despite this focus on math and literacy skills, a significant number of children arrive at kindergarten unable to demonstrate proper school readiness. Nature-based early childhood education (NbECE) is a growing alternative education option that prioritizes risky play, loose parts play, and nature play, potentially providing children with countless opportunities for school-readiness development through play. Guided by the biophilia hypothesis (Wilson, 1984), which suggests that humans are innately drawn …

Empowered Creation: Investigating Business Acumen And Technological Engagement Among Female Artists As Creative Entrepreneurs, Heggins-Jackson Tracey

Theses and Dissertations

The most powerful vehicle for communication and change is art. Creative endeavors have served humanity as a source of motivation and inspiration, as agents for shaping meaning and, most importantly, evoking empathy. Unfortunately, women in the arts face significant challenges due to deeply entrenched stereotypes, social expectations, societal norms, and gender-related misinformation, which result in destructive narratives. Paradoxically, this marginalized population possesses the skills and insights needed to address disparities through authentic narrative dissemination. Research indicates a limited focus on the contributions and pathways of women in the creative arts industry as entrepreneurs, explicitly highlighting their genuine needs conveyed through …

From Ink To Code, From Binary To Boundless Reality—Until All Returns To Emptiness, Weitong Sun

Theses and Dissertations

This thesis explores the entangled relationship between language, memory, and technology through the lens of immigrant experience. Moving from programming to visual storytelling, I investigate how dyslexia, bilingualism, and cultural displacement have shaped my ways of reading, writing, and coding.

Beginning with personal reflections on switching from computer science to art, I trace how code offered a form of clarity and expression where written language had once failed me. Yet as I ventured into real-time simulation and XR storytelling, I encountered new forms of mistranslation—where narratives dissolved, mutated, or resisted coherence altogether.

Through a series of experiments in code-driven art, …

The Cut Worm Forgives The Plow, August Neuscheler

Theses and Dissertations

The explorations in this thesis writing are centered on William Blake’s proverb “The cut worm forgives the plow.” It has been reinterpreted as an allegory of history and energy. A theory of their relation is proposed based on forgiveness, a theory that accepts the palimpsest of orders as evidence for the abundance of the present moment. The writing focuses on questions of proportionality, scale, archaeological screening methods, planar cutting, and a critique of entropy as grounds for this theory. Some of its subjects include the Statue of Liberty, Kate Raworth’s donut economic model, sashimi, triangulation, Joseph Beuys’ “7,000 Eichen,” semiconductors, …

A Parting Repast, Debra D. Dowden-Crockett

Theses and Dissertations

Both the thesis document and exhibition comprise the story of my journey through grief, examination of loss, contemplation of death, and transformation through acceptance and relinquishment. I conflate art and emotion to put form to the complex human experience of watching a loved one die, having to say a last goodbye, and the mourning that ultimately follows.

I examine the rituals surrounding death, the role of memory, and the symbolic presence of food as a shared experience of both mourning and nourishment, the intimate moments of mourning, and the gradual process of finding peace and closure.

Featuring works from a …

Between "Hippies In Suits" And "Money Is The Name Of The Game": Farm Animal Advocates' Analyses Of Political Power In The Farm Bill, Jeff Thomas

Theses and Dissertations

The animal agriculture industry annually slaughters roughly ten billion land animals in the United States. What can be done to improve their welfare and lessen their suffering?

Over the past decade, the problem of farm animal welfare and suffering has drawn increasing interest from the effective altruism community, a loose movement of utilitarian advocates seeking technocratic solutions to social problems (Singer, 2015). As effective altruism has become a more potent driver of the animal welfare movement, an increasing number of nonprofits have begun engaging in political advocacy for farm animal welfare. Facebook co-founder Dustin Moskovitz’ Open Philanthropy is the largest …

¡Bip Bip!, Diego Pablo Málaga Beckhart

Theses and Dissertations

¡Bip Bip! is a body of work that investigates the car as it exists in the American imagination, a metaphorical and physical object where culture, identity, and power intertwine. This work uses painting, printmaking, collage, video, and installation to explore the car as a space of expression, interiority, and understanding the world through a marginalized lens.

Central to my practice is my personal vehicle, Guadalupe, which functions as both muse and metaphor, the main driver of the framework within ¡Bip Bip! My practice examines the different but congruent contexts intersections of this iconic American symbol, the car. In my paintings, …

Beneath The Roots: Becoming Native Through Mangrove Teachings And Wisdom, Shima Aeinehdar

Theses and Dissertations

Beneath the Roots uses the wisdom of mangroves to investigate the naturalization of humans through science, spirituality, and storytelling. The seeds of Avicennia marina, the gray mangrove, drifted to Qatar at some point in history and took root, like so many other people here. The mangrove survives in a harsh saline environment through a unique salt excretion process. As a Qatar-born expat, I relate to this struggle to survive and nativize in a land that is both my own and foreign to me, in a cyclical conversation. I explore this nativization process through a ritual of salt extraction, creating botanical …

Development Of A Mediation Model Of Pain Cognition In Adult Patients With Sickle Cell Disease, Daniel M. Sop

Theses and Dissertations

Pain is a hallmark of Sickle Cell Disease (SCD), a genetic hemoglobinopathy characterized by chronic hemolytic anemia, vaso-occlusion, and organ damage. While acute vaso-occlusive crises (VOC) have been extensively studied, the mechanisms underlying chronic pain and its interplay with brain function remain unclear. This dissertation investigates the relationships between cerebral blood flow (CBF), fluid cognition, and pain sensitivity in adults with SCD, utilizing advanced imaging techniques and validated assessment tools.

Arterial spin labeling (ASL) and functional magnetic resonance imaging (fMRI) were employed to measure CBF and brain activity, respectively. Pain sensitivity was assessed using the Pain Sensitivity Questionnaire (PSQ), and …

Cannabis Use Among Cancer Survivors And The Impact On Cancer-Related Pain, Tiffanie A. Vargas

Theses and Dissertations

With a growing population of older adult cancer survivors—many of whom experience cancer-related pain—interest in medical cannabis as a pain management strategy has increased. This secondary analysis used data from the 2022 U.S. Behavioral Risk Factor Surveillance System (BRFSS) to examine cannabis use behaviors among cancer survivors and assess associations with cancer-related pain. The study had three aims: (1) to describe 30-day cannabis use (prevalence, intensity, and administration routes) by chronic health condition and cancer diagnosis, focusing on non-melanoma skin cancer, melanoma, and other cancers; (2) to compare demographics, health characteristics, and tobacco use by cannabis use status among cancer …

Inherited Wounds: Navigating Intergenerational Trauma Through Cooperative Play, Ayza Sheikh

Theses and Dissertations

'Strength' for Pakistani women is often defined as compromise, sacrifice, and silence. This definition has shaped intergenerational struggles in which women's self-narratives are constructed through suppression. Inherited Wounds seeks to address the trauma of suppression by creating a safe space for expression that fosters reflective and emotion-driven dialogue between Pakistani mothers and daughters.

Using interactive storytelling and embodied play, I developed a choice-based, narrative-driven video game and accompanying gesture-based controller. The game unfolds across childhood, marriage, and motherhood, mirroring the cycle of intergenerational struggle. Navigating choices in the game requires physical, intimate cooperation. The game uses the protagonist’s life as …

The Bitch And The Boogeyman: Violence Against Women And Gendered Morality In American Slasher Films, Davis A. Smith

Theses and Dissertations

This research examines the relationships between on-screen depictions of violence in American slasher horror films and depictions of gendered morality of victims. Slashers are a subgenre of horror film that arose out of the exploitation cinema movement of the 1970s that are characterized primarily by the presence of one or more human killers inflicting violence on a group of protagonists, typically through the use of bladed weapons. Data collected comes from a comprehensive set of thirty-six American slasher films that received a wide theatrical release, with exemptions for films whose primary genre is not slasher and only selecting three films …

Orb Weaver, Quinn Standley

Theses and Dissertations

Orb Weaver is a 24-minute experimental video/lm. This essay does not explain its meaning, as viewers should feel the power to trust their own interpretations. Instead, it reflects on the process of making the lm interwoven with autobiographical thoughts.

Substrate Preference And Foraging Behavior Of Two Declining Warblers In Appalachian Shrublands, Samantha Fishman

Theses and Dissertations

Abstract Shrubland and early successional habitats (ESH) support a diversity of wildlife, including many declining songbirds. However, nonnative shrubs increasingly dominate these habitats, potentially altering habitat quality by influencing prey availability. Habitat quality can be assessed by observing foraging behaviors of songbirds and identifying preferred and avoided substrates as well as testing the predictions of optimal foraging theory; specifically that birds will maximize their energy gain relative to the costs. We examined foraging behaviors of Golden-winged Warblers (Vermivora chrysoptera; GWWA) and Chestnut-sided Warblers (Setophaga pensylvanica; CSWA) in ESH on private lands in Virginia with varying amounts …

I Love Getting Mad At The Internet, Tariye George-Phillips

Unleashing Serine Palmitoyltransferase In Test Tubes And Mice, Matthew W. Peart

Theses and Dissertations

Canonically known both for structural contributions to lipid bilayers and roles in cell signaling, the sphingolipids comprise a dynamic, multifaceted class of molecules which are studied to understand homeostatic cell biology as well as pathophysiology. Sphingolipids contribute to tissue-specific structures such as myelin, a multilayer membrane that allows for rapid conduction of action potentials along neuronal axons. All sphingolipids are downstream products of the rate-limiting and initiating enzyme in the de novo sphingolipid synthesis pathway, Serine palmitoyltransferase (SPT). Demonstrative of its status as the enzyme that catalyzes a crucial step in a biochemical pathway, SPT activity is strictly regulated. This …
