Trait Mindfulness And Political Polarization: Investigating Neural Responses And Emotional Orientations, Elif Z. Celik

Theses and Dissertations

The rapid escalation of political polarization has led to increased social distancing, aggressive partisan behavior, and discriminatory attitudes among Democrats and Republicans. Prior research has indicated that mindfulness is associated with increased compassion, reduced prejudice, and diminished aggression toward out-group members. This thesis investigates the relationship between trait mindfulness and political polarization by examining neural responses and emotional orientations in individuals with varying levels of mindfulness. This research measured brain activity using functional near-infrared spectroscopy (fNIRS) while participants viewed emotionally charged political videos and neutral content. The primary hypothesis suggested that individuals with high trait mindfulness would exhibit left-lateralized prefrontal …

A Retrospective Chart Review Of Avulsion Injuries Treated At Virginia Commonwealth University., Ryan Hediger

Theses and Dissertations

A RETROSPECTIVE CHART REVIEW OF AVULSION INJURIES TREATED AT VIRGINIA COMMONWEALTH UNIVERSITY. By: Ryan Hediger, DMD

Objective: Outcomes related to healing following an avulsion injury are multifactorial. However, contemporary literature suggests that tooth survival can be enhanced after such injuries by promptly replanting the tooth and adhering to proper management guidelines. Despite the abundance of resources available, the actions taken immediately after the avulsion injury play a pivotal role in determining the fate of an avulsed tooth. The primary objective of the current investigation is to unveil prognostic factors associated with the survival of avulsed teeth.

Methods: A chart review …

Housing For Transgender And Gender Expansive People In The U.S. South, Aaron M. Kemmerer

Theses and Dissertations

Housing is a prominent issue for transgender and gender expansive (TGE) people around the world. There is a dearth of research about TGE people experiencing homelessness (TGE PEH) in the U.S. South. This dissertation aims to amplify the voices of TGE Southerners around the social concerns of housing and homelessness – this work also disrupts gendered and racialized narratives about housing injustice, exposing the salience of intersectional discrimination and cisgenderism in housing outcomes for TGE people. Using narrative and visual methods, this dissertation re-presents stories and recommendations from in-depth interview data collected from a small qualitative sample of Southern TGE …

Moonshine Babies, Arghavan Heydareslam

Theses and Dissertations

Moonshine Babies is a two-screen film made of collage/cut-out stop-motion and live-action. It is a visual poem based on my journals from when I recently started living in the US as an outsider. The experience left me feeling divided between the empty present and memories of the past. suggesting that there are collective memories among a group of interconnected individuals that unite them within a single narrative.

There was a moment when I asked, "If you are your memories, what does it mean to be somewhere you have no memories of and no one has memories of you there?"

Memories …

Unfolding Remembrance: Folding Islamic Principles Into Pondering Machines, Hind Al Saad Al-Kuwari

Theses and Dissertations

Principles of early Islamic art can be surveyed as a precursor to Western computational art. Though produced in different historical and cultural contexts, Islamic art and computational art are connected by underlying structures—arithmetic, harmony, and the concept of the Infinite.

Islamic developments in knowledge, like algebra, contributed to mathematics and mechanics—the building blocks of contemporary technology. Returning to Islam’s traditional harmony between religion and science, my creative practice constructs machines as an act of worship (ʿibadah), folding Islamic principles into the medium of computation.

Selected verses from the Quran are used as the core of each automaton (self-operating machine). Their …

Intersectionality, Racial Discrimination And Oral Healthcare Utilization Among Black Adults In Baltimore City, Maryland, Briona M. Phillips

Theses and Dissertations

INTRODUCTION: Oral health is essential for overall well-being, yet disparities persist, particularly among marginalized populations including Black adults. Limited access to and underutilization of oral healthcare services exacerbate these disparities. Discrimination, both individual and systemic, acts as a significant barrier to accessing care, contributing to disparities in oral health outcomes. Individuals facing discrimination experience mistrust and fear within oral healthcare settings, leading to delayed or avoided care. Therefore, investigating and addressing discrimination among Black adults is essential for promoting equitable access to oral healthcare, improving overall oral health outcomes, and lessening existing disparities.

PURPOSE: The purpose of this dissertation was …

Examining The Relationship Between Racism-Related Stress And Coping Among Black Adolescents: A Linked Lives Perspective, Kenna Yadeta

Theses and Dissertations

As Murry and colleagues (2018) note, racism serves as a family-level stressor, impacting both Black adolescents and their parents. As Black teens continue to experience frequent and varied racism experiences (English et al., 2020), their Black parents are facing a double challenge: bearing the weight of their own experiences with racism, while also parenting a Black adolescent through the same. Recent frameworks (e.g., Gilligan et al., 2018) highlight the linked experiences of Black families, in dealing with their stress and coping. As such, the current study aimed to explore the ways that both adolescent and parental experiences with racism related …

Insights Into The Characterization And Degradation Of Electrospun Polycaprolactone Scaffolds For Tissue Engineering Applications, Caleb B. Wells

Theses and Dissertations

Electrospun polymeric biodegradable scaffolds are essential in tissue engineering, particularly for Engineered Tissue Vascular Grafts (ETVGs), which promise advancements in treating coronary artery disease, peripheral arterial disease, congenital cardiovascular defects, and renal disease. These scaffolds present a solution to issues with autologous graft availability and durability. While large-diameter grafts in low-pressure environments have seen success, small-diameter grafts in high-flow scenarios remain challenging. Understanding polymeric scaffold degradation and behavior during incubation, especially under dynamic mechanical loading, is vital for clinical translation of small-caliber ETVGs.

This research focuses on characterizing the mechanical and microstructural properties of electrospun polycaprolactone (PCL) scaffolds and their …

Friends In Fiction: Bonding With Fictional Characters Introduced Through Fictional Narrative Positively Affects And Interplays With The Psychology And Social Behaviors Of Adults To Influence Engagement, Vishnupriya Alavala

AUCTUS: The Journal of Undergraduate Research and Creative Scholarship

Just as people can form relationships with each other, they can befriend and interact with characters. As broadening media outlets continue to introduce fictional characters, it is vital to understand the effects relationships with characters, referred to as parasocial phenomena, have on individuals. In turn, this will offer a new perspective on the effects of engaging with fiction. Bonding with fictional characters introduced through television or print narratives affects and interplays with the psychology and social behaviors of adults. Most studies support the positive effects of parasocial phenomena in terms of personality, mindset, and social skills. Other studies state that …

Persistence Of Wastewater-Associated Antibiotic Resistant Bacteria In River Microcosms, Aoife P. Mahaney

Theses and Dissertations

The spread of antibiotic-resistant bacteria (ARB) associated with wastewater is a significant environmental concern, but little is known about the persistence and proliferation of these organisms in receiving water bodies after discharge. To address this knowledge gap, we performed a series of microcosm experiments in which river water was amended with either untreated or treated wastewater, and the abundance of viable ciprofloxacin-, Bactrim-, and erythromycin-resistant bacteria was monitored for 72 hours.

Both types of wastewater amendments increased the initial abundance of ARB compared to microcosms containing only river water. The increase was greatest with untreated wastewater, but that effect decreased …

Effects And Mechanisms Of Smartphone-Based Mindfulness Training On Emotional Experience, Polina Beloborodova

Theses and Dissertations

Emotional well-being is an important component of mental and physical health that includes both positive emotions and an absence of emotional symptoms (e.g., depressive- and anxiety-related). In this study, we examine psychological mechanisms that help to explain the effects of an digital mindfulness-based intervention (MBI) on emotional states. We conducted a randomized controlled trial wherein undergraduate student participants vulnerable to decreased positive and increased negative affect received a 2-week smartphone-based MBI or a structurally equivalent coping control intervention. Emotional experience, including depressive feelings, anxiety, and happiness, as well as subjective social well-being, including loneliness and felt connection to others, was …

A Walk In The Woods, Caitlin Mclean

Theses and Dissertations

A connection with nature fosters increased appreciation, admiration, and responsibility toward the natural environment, thus encouraging the mindful use of its resources and preservation of both species and their habitats. Defined by Mayer and Frantz (2004) as an “experiential sense of oneness with the natural world”, this connection is more important now than ever in this highly digital era. Studies indicate that limited exposure to nature can negatively impact the activation of neural pathways associated with pro-environmental attitudes and behaviors (Chawla, 2020), while further research shows that engagement with the outdoors during childhood as a significant life experience (Chawla, 1998), …

"I Call Them Supermoms": Therapists' Reflections On The Impact Of Youth Sexual Offending On Latina Mothers, Mauricio P. Yabar

Theses and Dissertations

Families of youth who have sexually offended often suffer significant collateral consequences following the discovery of the sexual offense. Samples in research with these families disproportionately consist of mothers and other female parental figures. This is rarely acknowledged in the literature, and the experiences of these mothers have not been explicitly examined. In addition, research on the experiences of these families has largely ignored factors related to race and ethnicity. This is a significant oversight considering the prevalence of systemic racism and discrimination in the United States, particularly in the systems with which these families must interact (e.g., juvenile justice …

Identifying Mechanistic Pathways To Rigidity Associated With Obsessive-Compulsive Personality Disorder Traits Using A Novel Decision-Making Paradigm, Hannah L. Heintz

Theses and Dissertations

Cognitive and behavioral rigidity is observed across several mental disorders and is a defining characteristic of Obsessive-Compulsive Personality Disorder (OCPD), a highly prevalent and debilitating, yet understudied, disorder. In particular, treatments for OCPD are underdeveloped due to our poor understanding of the mechanisms leading to the disorder’s key feature of rigidity. Two related disorders, anorexia nervosa (AN) and obsessive-compulsive disorder (OCD), have shown distinct mechanistic pathways leading to symptoms of rigidity, indicating that this trait can arise as a result of a number of differentially impaired cognitive processes, each requiring unique interventions. To examine the relationship between symptoms of OCPD …

Latent Profiles Of Child Coping And Perception Of Experience Processes To Predict Long-Term Symptoms Of Depression, Intrusive Grief, And Suicidality Outcomes In Parentally Bereaved Children, Rebecca Hoppe

Theses and Dissertations

Childhood bereavement is a significant public health issue and the most distressing form of childhood trauma. The death of a parent can disrupt the course of a children's development and potentially predispose them to enduring adverse mental health outcomes, such as depression, intrusive grief, and suicidality. Recognizing grief as a dynamic process, theories have suggested that children’s unique coping and perceptions of experience can contribute to variations in individual adaptations to the death and the onset of mental health problems. The goals of this study were to (a) use latent profile analysis to empirically group recently bereaved children into distinct …

Advanced Synthesis And Rational Design Of Support Structures For Nobel Metal Heterogeneous Catalysis: Towards Enhanced Activity And Continuous Processes, Brian R. Clark

Theses and Dissertations

The field of catalysis has a wide-ranging impact. Our group has identified the constant need for improved catalytic activity in high-impact applications such as hydrosilylation and cross-coupling reactions. For these reactions, precious metal catalysts often exhibit markedly better performance than their counterparts, but they can be a significant process cost that decreases overall economic efficiencies. To address this challenge, we explored support structures that can enhance catalytic activity at low metal loadings and improve precious metal recovery through simple filtration. We found that a platinum on graphene nanoplatelet catalyst (PtGNP) synthesized via strong electrostatic adsorption with microwave irradiation (SEA-MW) exhibits …

The Effects Of Various Nanoplastics On The Inflammatory Response In Primary Alveolar Epithelial Cells, Eunice J. Pak

Theses and Dissertations

As plastic pollution begins to multiply in the environment and the workplace, gradual degradation of these plastics creates an unseen threat to biological health: nanoplastics. These nanoplastics are common in day-to-day life, and have been found in various internal organs of the human body. The biological and health effects of these nanoplastics are still widely unknown, and only recently has research focused on the impacts of these particles on human health at the cellular level.

In this thesis, poly(methyl methacrylate) and three forms of polystyrene (carboxyl-modified, amine-modified, and neutral surface charge) have been tested on submerged primary C57BL/6 mouse alveolar …

How To Forget, Jesse D. Hoyle

Theses and Dissertations

How To Forget was born from a need to give tangible form to the psychic residue left behind by a life lived. Through the use of silk-screening of red clay mud onto ink-jet photographs, archival textiles, and site-specific installations, I attempt to tie and/or divorce myself from my own and my family's extended history and examine the function of memory within the dynamics of the archive. How To Forget takes a non-linear, non-chronological approach to this examination, compressing decades of time and space through the manipulation of the archive and my own self-portraiture, designed specifically to deny myself from its …

The Incoherence Of Orientalists, Sarah Zaid Alafifi

Theses and Dissertations

Orientalism, the Western practice of fetishizing cultures, extends beyond mere misrepresentation of the “other;” it epitomizes the underlying structures of colonialism and imperialism, infiltrating everyday life and eroding the moral fabric of Islamic society.

This thesis analyzes colonial control through the exercise of political power and the production of knowledge, investigating key events related to Napoleon’s Egyptian campaign and the narratives of resistance that emerged in opposition to it.

Through the lens of this 18th-century expedition, the study examines how Western knowledge systematically contributed to the dismantling of Islamic systems of knowledge. Select phrases from Colonial-era printed proclamations are extracted …
