Double Jointed: Gendered Flexibility And The Overextended Self, Grace A. Bromley

Theses and Dissertations

This thesis explores compulsory domesticity and the impulse to overextend oneself, both pressures often associated with the construct of femininity. Through diving into my personal history, which includes growing up in a three-generational home of women, I explore mimesis as it functions in both the replication of identity and in terms of pictorial representation; specifically I address its relationship to gender, manifestation within the body, and the search for subjectivity through the process of making and thinking. In various forms of material explorations, I play with ideas of malleability, mimicry and “embedded” behaviors that are passed down and embodied in …

Investigating The Protein Interactome Of Escherichia Coli To Understand Metabolic Regulation When Proteins Bind: A Systems Biology Study., Shomeek Chowdhury

Theses and Dissertations

Proteins bind other proteins and work together as machines to perform many biological functions. Metabolic enzymes governing the life-sustaining metabolic reactions and therefore, metabolism are proteins which also binds other proteins. In this dissertation work, I have explored proteins when they interact with metabolic enzymes, play any role in regulating the cell’s metabolism. I study this phenomenon in Escherichia coli whose protein-protein interaction data is readily available in public databases with proper reference to the experimental study. Another good reason is the predictions we make in this computational study can be tested and validated in E. coli as it is …

May Your Flight Be Smooth, The Wind Calm, The Cloud Safe, And The Sky Blue!, Kai Chuang

Theses and Dissertations

They were born in a port city, on an island. In their eyes, many things seemed like the water. Fluid, compound, and ambiguous. Those things shift shapes with their containers, blending with elements from various sources, carrying multiple meanings, images and interpretations.

The sea is deep and endless, similar to stories, quests and dreams.

The coastline is a constant dialogue among the land, the ocean, the wind, organisms, physics, the past, randomness, and chance…When they think about boundaries, they recall the coastline.

The Neural Mechanisms Of Inter-Friend Aggression, Wyatt Brown

Theses and Dissertations

Decades of research concerns intimate partner aggression (IPA). While important to understand and prevent, investigations of IPA largely ignore another vital social relationship: close friendships. To investigate aggression between close friends – inter-friend aggression (IFA) – functional neuroimaging analyses enable to assessment of neural activity and mental representations of aggression in different social relationships. As such, 98 participants completed the well-validated Taylor Aggression Paradigm modified for a magnetic resonance environment against their current romantic partner, a close friend, and a stranger. Univariate analyses assessed the differences in the degree of neural activity and the role of Narcissism and negative urgency …

Associations Among Acculturative Stress, Body Ideal Internalization, Body Dissatisfaction And Disordered Eating Behaviors Among Cisgender Heterosexual And Lgbt People Of Color, Taryn Henning

Theses and Dissertations

Research supports the relation between acculturative stress and disordered eating behaviors (DEBs) across racially and ethnically diverse groups of men and women. However, there is minimal research examining factors that further explain the relation between acculturative stress and DEBs. Also, this relation has not been evaluated in racially and ethnically diverse LGBT individuals. The current study aimed to address these gaps by examining the role of thin-, muscular-, and hourglass-ideal internalization and body dissatisfaction as mediators of the relation between acculturative stress and disordered eating behaviors among cisgender heterosexual Black, Latine, Asian American, Multiracial men and women and LGBT men …

Reflection: Cultivating Creativity And Healing Through Art Therapy, Caroline Ciccone

Theses and Dissertations

I was first introduced to the healing powers of art after working in an orphanage in Jamaica with children who had a wide range of disabilities. Some children were mute or unable to communicate, but art was a form of communication that brought us all together. Within the City of Richmond public school system, 31.7% of students are economically challenged and 13.1% of students are disabled (Education, 2022). Giving more resources in the arts and mental health support to students outside of their school environments is the goal. Art therapy helps reduce the dropout rate and improve mental health (10 …

The Merit Of Adaptation: An Exploration Of Adaptation In Regard To Sophocles’ Theban Plays And The Role Of Antigone Within The Story, Hogan T. Holt

Theses and Dissertations

The creation of an adaptation is extremely challenging and time-consuming, but with the right tools and inspiration, that task of creation can be eased. By looking at three different adaptations of the Theban plays, the goal of creating a new adaptation of this series of plays can be achieved. At the same time, this adaptation can achieve a goal of highlighting an important character from the original set of plays, Antigone, and give her a role that elevates her to the main protagonist across all three plays, thus allowing the Theban plays to become a more feminine piece that works …

Side Effects, Shannon R. Kurzyniec

Theses and Dissertations

Through the exploration of the personal and social impacts of prescription medications on the human condition, I have discovered that the side effects of prescription medications on myself and others are much greater than I had ever anticipated. The deeper I dig into my subconscious, the further back I find that the impact was created. Most of us are taught at a young age to take medicine when we don’t feel well. Stomach ache, headache, sore throat, fever, even the imaginary boo boo is given a pill to cure. As we age we begin to reach for pills due to …

Zaytouna: Rooted Histories In Uprooted Memories, Naima M. Almajdobah

Theses and Dissertations

Palestinians, whether living under occupation or—like myself—in the diaspora, experience a complex journey of displacement and dispossession stemming from the Nakba of 1948. This reality shapes our collective identity, rooted in our connection to our homeland.

Zaytouna explores an under-researched topic: the relationship between the olive tree and uprooted Palestinians. It reveals a rich tapestry of narratives that encompass the quintessential and everlasting relationship between a land and its people. The resulting interactive archival installation consists of two parts: audio recordings from Palestinians in the diaspora, which capture their memories and voices; and visuals, which represent the storytellers’ places of …

Single-Molecule Pulldown (Simpull) For Detection Of Gpcr Complexes In Mammalian Cells, Julie M. Kraft

Theses and Dissertations

G protein-coupled receptors (GPCRs) constitute the most numerous and diverse superfamily of cell membrane receptors. While GPCRs can perform signal transduction as monomers, evidence suggests they also function as homo- and hetero- dimers and oligomers. These diverse quaternary structures can affect GPCRs’ downstream cellular signaling, pharmacological properties, and regulation of internalization.

The single-molecule pulldown (SiMPull) assay combines a co-immunoprecipitation assay with single-molecule total internal reflection fluorescence (TIRF) microscopy and can be used to probe the stoichiometry of GPCR oligomers in mammalian cells.

This project replicates the SiMPull assay by confirming the quaternary structure of mGluR2 homodimers. Plasmid constructs SNAP-mGluR2-HA and …

Tchu Tcha Tcha: The Transformative Role Of Funk, Adriane De Souza

Theses and Dissertations

Cultural disconnection and homesickness are part of expatriate life. My research investigates the transformative power of Brazilian funk, which, for me, evokes restorative memories of home and life in Rio de Janeiro.

Originating in North America, funk made an exciting leap and found a new home in Brazil, particularly in Rio de Janeiro. Over time, it has become firmly established and thoroughly Brazilianized, infused with local instruments and influences, leading to the emergence of a new genre of music known as Brazilian funk.

Transplanted again, to Qatar, this work celebrates the migration of funk through a combination of still images, …

Established Colonization Of Sneathia Vaginalis In A Mouse Model, Kailyn E. Turcios-Gonzalez

Theses and Dissertations

Sneathia vaginalis (Sv) is a gram-negative anaerobic bacterium associated with adverse reproductive outcomes. Sv can traverse the fetal membrane and damage epithelial cells in vitro by producing a pore-forming cytotoxin, cytopathogenic toxin A (CptA). To further understand the transition of Sv from normal flora to a pathogen, an animal in vivo model needs to be created to observe the preliminary ascending infection before we begin to study the effects on pregnancy. Experimentation was conducted to optimize mouse breed, bacteria administration methods, and other variables that arise when working in vivo. The C57BL/6 mouse strain displayed the most consistent …

Supervisor-Subordinate Communication In The Contemporary Audit Environment, Devon P. Jefferson

Theses and Dissertations

Just five years ago I was working as an Audit Manager in person (in the office or at the client site), amongst each of my subordinates, which made common work practices like knowledge sharing, responding to questions, and building team morale easy. Since then, remote work has become the new norm, which has significantly changed the communication dynamics between supervisors and subordinates. This dissertation is my personal pursuit to understanding how supervisor and subordinate auditors are currently interacting to achieve desired work outcomes, and identifying specific areas where challenges may exist. I accomplish this objective through four papers, including a …

Capiz Reborn: Preserving And Enhancing Traditional Philippine Shellcraft, Destarte A. Prieto

Theses and Dissertations

The capiz shell is a thin, translucent exoskeleton of a mollusk found in the Philippine Sea. Traditionally, capiz shells were made into window panes and home decor, used so widely they became an iconic part of Philippine identity. Today, the influx of cheap, mass-produced merchandise threatens the capiz shell industry. To encourage renewed interest and sustainable revival of this long-standing industry, my research demonstrates new possibilities for the capiz shell.

In reconstituting cast-off bits and shell trimmings to form a new capiz biomaterial, my work is informed by the three traditional techniques used by Philippine capiz artisans—sewing, welding and bonding. …

Call For Me When You Get There: I'Ll Be Among The Crows, Jessica O. Tifase

Theses and Dissertations

I've always been intrigued by the ways in which the notion of flight has been used to describe the movement of Black people, both literally and figuratively. In many instances, flight performs as a double entendre, embodying multiple meanings: to escape or to transcend. The fluidity of its definition prompts a reflection I’ve been wrestling with as I move through the world: Are Black people in a perpetual state of flight?

In my thesis exhibition, Call for Me When You Get There, I use the precarious state of flight as a means to explore the complicated choreography necessary for navigating …

Fear Of God: Exploring Transformative Potential, Misunderstanding, Systemic Challenges, And The Future., Jermaine Ollivierre

This personal journey is a testament to the transformative power of play within my practice. It is a love story between me and the institution, sparked by my fervor for communal creativity in a graduate school environment. Through creative endeavors like public art installations and silent artist talks, I confront racial dynamics and institutional reluctance to engage with complex issues like Black Lives Matter. My personal experiences of alienation are woven into the broader themes of community building, communication, and systemic change. I navigate the complexities of group mentality and exclusion by deliberately using unconventional forms of expression, such as …

Asymmetric Cuh-Catalyzed Reductive Coupling Of Allenamides With Carbonyl And Imine Electrophiles, Stephen Collins

Theses and Dissertations

The carbon scaffold of many drugs and natural products contain multiple stereogenic centers bearing heteroatoms. As a result of this, chemists have long sought methods to efficiently install these multi-heteroatom functionalities. Reductive coupling reactions have been extensively studied over the past decades, and the allylation of carbonyls via the reductive coupling approach has been a key method for generating chiral allylic alcohols. This work utilizes inexpensive Cu for the asymmetric reductive coupling of allenamides with carbonyls or imines to simultaneously install two heteroatoms (either oxygen and nitrogen or nitrogen and nitrogen, respectively) onto the product. These molecules have a polarity …

Modeling Of Macroscopic Melt Splashing On Beryllium First Wall Panels Of Fusion Tokamaks Under Off-Normal Events, Cheng Zhang

Theses and Dissertations

Beryllium (Be) is a material which is used as a plasma facing component in tokamak reactors due to its unique properties of high thermal conductivity, low density, and high strength. However, under extreme conditions of high temperature and pressure, Be can melt on the surface of armor tiles and molten droplets can be ejected into the reactor chamber leading to disruption of fusion plasma. The variations of pressure, mass density, velocity, and temperature of Be vapor on the surface of melt layer as well as magnetic field strength and direction can influence the splashing of Be melt and their effects …

Paley Graphs, Prime Graphs, And Crossword Puzzles, Robert D. Jacobs Jr.

Theses and Dissertations

In this paper, we will talk about many different mathematical concepts. We will prove theorems about Paley graphs, prime graphs, and crossword puzzles. It will be very fun.

The results in the section about Paley graphs include structure theorems about the subgraph induced by the quadratic residues, the subgraph induced by the non-residues and a few related subgraphs. The main is to better understand the “independence structure” of the Paley graph itself. No good upper bound on the independence number of Paley graphs is known. Theorems about these subgraphs, and various counts aim at future improvement of upper bounds for …

Acute Effects Of An Oral Nicotine Pouch In People Who Use Smokeless Tobacco, Alisha Eversole

Theses and Dissertations

People who use smokeless tobacco (SLT) are exposed to a variety of carcinogenic toxicants, yet, despite health risks, nearly 6 million people in the US use SLT. SLT contains and delivers nicotine, a psychostimulant that causes dependence and hinders cessation efforts. An orally-administered nicotine pouch marketed as “tobacco-free” recently has become available for purchase in the US. However, there are very few non-industry-sponsored studies regarding the effects of these oral nicotine pouches.

The current study used clinical laboratory methods to determine the acute effects of an oral nicotine pouch in people who use SLT. Participants completed four sessions (within subjects, …

Mental Health Help-Seeking Behaviors And Service Utilization Of Black College Students, Troy J. Keys

Theses and Dissertations

Black college students are less likely to seek mental health services compared to other students. While previous research has identified barriers and facilitators contributing to Black college students’ help-seeking behaviors, the current political and social climate and pandemic have negatively impacted their mental health thus warranting the exploration of these factors again. This study aimed to identify the mental health help-seeking behaviors and attitudes of Black college students, the barriers and supports for help-seeking behaviors, their preferred service utilization providers, and their thoughts about promoting mental health help-seeking among their peers. Black college students (n = 21) enrolled at an …

Assessing Providers’ Readiness To Integrate Mat Services In A Primary Care Setting, Carmen Ingram-Thorpe

Theses and Dissertations

Opioid use disorder is a growing concern in the United States. Despite medication-assisted treatment (MAT) being a more effective treatment option than behavioral treatment alone, primary care providers’ rate of adoption and utilization of MAT has not matched the demand of the opioid crisis. The largest barrier facing our local community is the availability of organizations and providers that can and will actually provide MAT services. The purpose of this study was to identify factors that impact primary care providers’ readiness to treat individuals with opioid use disorder (OUD) using MAT. This study used the ADKAR model as framework, which …
