Changing Her Habit: Women Writers And Needlework In Early Eighteenth-Century England, Jane B. Harwell

Theses and Dissertations

This thesis attends to the appearance of needlework within early eighteenth-century British women's writing. The central goal of this work is to complicate the seemingly oppositional relationship between the needle and the quill, as applied to women surrendering needlework for written work. Popular representations of needlework within early novels demonstrate an elision between text and textile. Further, both female-authored work and the lack of surviving embroideries elucidate the ephemerality of what is broadly defined as "Women's Work." I focus on texts between 1700-1750, however the material examples of embroidery were created as early as 1570. This timeline helps illuminate the …

Out Of The Margins: Evolving Narrative Representation Of Women In Video Games, Rowan Lucas

Theses and Dissertations

This thesis examines narrative representation of female characters in video games and how game narratives and representations contribute to socio-cultural discourse. First, this thesis explores and defines the cultural background for female representation in video games. It then defines video games as a type of text and describes the features that are unique to games, such as the use of avatars, and what impacts these features have on game narratives. The thesis attempts to establish evidence of an evolutionary arc of comprehensive female representation in video games by first exploring historical female narrative tropes, and then comparing them to narrative …

An Introduction To Supersymmetric Quantum Mechanics, Vincent R. Siggia

Theses and Dissertations

In this thesis, the general framework of supersymmetric quantum mechanics and the path integral approach will be presented (as well as the worked out example of the supersymmetric harmonic oscillator). Then the theory will be specialized to the case of supersymmetric quantum mechanics on Riemannian manifolds, which will start from a supersymmetric Lagrangian for the general case and the special case for S2. Afterwards, there will be a discussion on the superfield formalism. Concluding this thesis will be the Hamiltonian formalism followed by the inclusion of deforma- tions by potentials.

Searching For Clean Observables In $B -> D* /Tau- \Bar{\Nu}_{\Tau}$ Decays, Michael D. Williams Jr.

Theses and Dissertations

In this thesis, the clean angular observables in the $\bar{B} \to D^{*+} \ell^- \bar{\nu}_{\ell}$ angular distribution is studied. Similar angular observables are widely studied in $B \to K^* \mu^+ \mu^-$ decays. We believed that these angular observables may have different sensitivities to different new physics structures.

Nanostructured Materials For Photocatalysis, Water Treatment And Solar Desalination, Hiran D. Kiriarachchi

Theses and Dissertations

Maintaining a constant supply of clean drinking water is among the most pressing global challenges in our time. About one-third of the population is affected by the water scarcity and it can only get worse with climate change, rapid industrialization, and the population growth. Even though nearly 70 percent of the planet is covered by water, the consumable freshwater content is only 2.5 percent of it. Unfortunately, the accessible portion of it is only 1 percent. Even so, most of the freshwater bodies are choked with pollution. Considering the vast availability of saline water on the planet and the increasing …

Architect Of The New South: The Life And Legacy Of William Mahone, Heath M. Anderson

Theses and Dissertations

In Virginia following the Civil War, white and black people formed complex and shifting alliances based on their own self-interests that cut across the lines of established political parties. In this turbulent atmosphere, William Mahone forged a new biracial political coalition called the Readjuster Party in order to transform Virginia’s economy so that it would be competitive in the years to come. Chapter One argues that Mahone’s experience as a soldier and railroad man gave him the political clout needed to enter politics and an industrial vision for Virginia’s future that was markedly different from many of his contemporaries. Chapter …

Generic Of, Nicole Levaque

Theses and Dissertations

generic of is a creative text paralleling the creation of my thesis exhibition. I use fragmented layers of narrative, description and prose in the same way each handbuilt ceramic is fired multiple times, allowing the glazes to build upon themselves. This is a close study of the still life, the intimacy of consuming, and how trauma is passed through the gut.

Electronic And Geometric Structure Of Alnom And Alnom +, Albert R. Armstrong

Theses and Dissertations

Generally, the electronic stability of aluminum clusters is associated with either closed electronic shells of delocalized electrons, or aluminum in the +3 state. To explore alternative routes for electronic stability in aluminum oxide clusters, theoretical methods were used to examine the geometric and electronic structure of Al_nO_m (2≤n≤7; 1≤m≤10) clusters. Two types of electronically stable clusters with large HOMO-LUMO gaps were identified the first being Al_2nO_3m clusters with a +3 oxidation state on the aluminum, and the second being planar clusters such as Al₄O₄, Al₅O₃, Al …

Humans Aren't Boxes, Art Isn't Finite, Brianne Alta Humphreys

Theses and Dissertations

I am bored. All around me are systems that perpetuate repetitive, reductive, and mundane modes of living. In an attempt to counter a culture obsessed with singular ways of existence and bite-sized perfection, I utilize moving mediums of video and performance to dive head first into a vast array of sloppy sincerity. The crisp, white-washed, analytical, and restrictive is loudly replaced with the empirical, haphazard, and instinctual. My intention is to create and encourage raw, performative-based work that is as multifaceted as unbridled life itself. This alive and physical practice hosts a conglomeration of sweat, memories, heartbreaks, hymn singing, line …

Whirling Hybrids: A Dichotomy Of Belonging, Rabeya Khatoon

Theses and Dissertations

Migration is a phenomenon wherein individuals relocate from one country to another, albeit temporarily or permanently, for numerous reasons. The State of Qatar is a highly diverse nation with a large population of foreign residents. According to Priya D’Souza, as of 2017, 60 percent of the resident population in Qatar are from South Asia. Growing up in this environment, third culture kids develop a unique, hybrid culture through experiencing multiple cultures. This research investigates a dichotomy of belonging from the perspective of South Asians in Qatar. A series of hybridized spinning tops were produced in collaboration with a South Asian …

Characterizing The Cellular Nature Of The Physical Interactions Necessary For Collective Neuron Migration, Rebecca Vareed

Theses and Dissertations

Neuronal migration is an essential process in the development of the nervous system. Neurons are born in one location and migrate sizable distances to their final location. In many other developmental processes, cells migrate as collectives, where the migration of one cell influences the migration of another cell; this process has yet to be shown in the developing central nervous system. Using the conserved tangential migration of facial branchiomotor neurons (FBMNs), I aim to determine the nature of the collective migration in the developing nervous system. Here, two models of FBMN collective migration are tested: the “Pioneer” model, where following …

Alcohol Use And Drinking Motives In Bereaved Undergraduates, Laura J. Smith

Theses and Dissertations

This study examined the effect of the experience of a loss on alcohol use and drinking motives in a college sample. Participants for this study were drawn from the “Spit for Science” project (Dick et al., 2014). The sample included 3,013 students (31.8% men, 68.2% women; 44.3% White, 21.1% Black, 19.6% Asian, 6.0% Latinx; mean age = 18.96; 16.2% bereaved) from Virginia Commonwealth University. Data were collected from participants’ freshman spring and sophomore spring time points on the Life Events Checklist, Alcohol Consumption items, and Drinking Motives Questionnaire-Revised. Participants who were bereaved between the freshman and sophomore timepoint did not …

The Walls We Put Up - Loneliness And Belonging In Urban Co-Living, Richard Rozewski

Theses and Dissertations

ABSTRACT

Concurrent issues of social isolation and loneliness have long been recognized as problems that affect seniors but it is also being proven to affect young people as well, specifically with the rise of new technologies and a perception of connectedness. Co-living provides one alternative design solution to traditional housing models which can unlock a range of social benefits.

MOTIVATION

Loneliness is an unfortunate reality of modern life and it is something that most people experience at least once in their life (Cacioppo & Patrick, 2008). A study carried out by Berguno, Leroux McAinsh, Shaikh (2004), showed that 80% of …

Expansion Of The Genetic Code To Include Acylated Lysine Derivatives And Photocaged Histidine, William D. Kinney

Theses and Dissertations

The genetic code of all known organisms is comprised of the 20 proteinogenic amino acids that serve as building blocks on a peptide chain to form a vast array of proteins. Proteins are responsible for virtually every biological process in all organisms; however, the 20 amino acids contain a limited number of functional groups that often leaves much to be desired. The lack of diversity addresses the need to increase the genetic repertoire of living cells to include a variety of amino acids with novel structural, chemical, and physical properties not found in the common 20 amino acids. In order …

Graphic Intimacies: Identity, Humor, And Trauma In Autobiographical Comics By Women Of Color, Francesca Lyn

Theses and Dissertations

Graphic Intimacies: Identity, Humor, and Trauma in Autobiographical Comics by Women of Color examines works of comics art about the lived experience of the comics’ creator. These graphic narratives address racialized difference and the construction of identity while also using humor to negotiate their narrations of traumatic events. I argue that these creators employ the structure of comics to replicate the fragmentary nature of memory. Comics allow for the representation of trauma as being intimately linked to corporeality. The comics medium allows creators to make visible and present fractured versions of the self, a product of traumatic fragmentation. Drawing traumatic …

Manufactured By Nature: Growing Generatively Designed Products, Mohammad Jawad

Theses and Dissertations

Mass production and assembly lines are yesterday’s manufacturing methods. They have exhausted Earth’s resources and limited the possibilities of design in terms of both form and material, prompting designers to search for new processes. A new generation of making includes biomimicry-inspired technologies such as 3D printing and parametric simulation, which have transformed the production paradigm. Utilizing nature as industry, this thesis explores the possibility of “growing” designed objects by employing nature’s own processes and resources. It integrates bio materials, generative design and additive manufacturing to produce objects for a post-industrial world. The project outcomes employ natural minerals, crystallization and 3D …

Design And Testing Of An Agonist-Antagonist Position-Impedance Controlled Myoelectric Prosthesis, Christopher Aymonin

Theses and Dissertations

Intuitive prosthetic control is limited by the inability to easily convey intention and perceive physical requirements of the task. Rather than providing haptic feedback and allowing users to consciously control every component of manipulation, relegating some aspects of control to the device may simplify operation. This study focuses on the development and testing of a control scheme able to identify object stiffness and regulate impedance. The system includes an algorithm to detect the apparent stiffness of an object, a proportional nonlinear EMG control algorithm for interpreting a user’s desired grasp aperture, and an antagonistically acting impedance controller. Performance of a …

(And I Can't Stress This Enough) In My Mouth: Extradiegetic Affect As Material, C. Klockner

Theses and Dissertations

(and i can’t stress this enough) in my mouth: Extradiegetic Affect as Material is a non-linear exploration into the structures of feeling that exist in relation to cinema in its role as a technology for generating subjectivity. In the development of this research, a proposal of cinema’s likeness to the ecological circulation of microplastics is drawn in order to illustrate cinema’s materiality and nearly invisible ubiquity. The notion of extradiegetic affect is outlined as a post-cinematic condition in which lived experience becomes secondary to cinematic representation and which, simultaneously, becomes directly shaped by engaging with these representations.

Lotion In Your Lungs, Raul H. De Lara

Theses and Dissertations

This is a document explaining in detail my artistic practice from childhood to the day I graduated VCU. It will perhaps only be understood by those who have themselves already felt such ways, or similar ways – words and ghosts are mostly invisible.

A Spectacle And Nothing Strange, Taylor Z. King

Theses and Dissertations

Working through methods of abstraction and comedic mimicry I choreograph awkwardly balanced sculpture with objects of adornment as a means to defuse personal sensitivities surrounding my experiences of gender, desire, and home. The research that follows is concerned with the adjacent, the in between, above and underneath, because I feel that this kind of looking means that you are, to some degree, aware of what lies at the edges. Maybe this is what Gertrude Stein means to act as though there is no use in a center—because this concerns a way of relating, though there are many things in the …

Development And Characterization Of Stationary Phase Gradients For High Performance Liquid Chromatography, Anna Forzano

Theses and Dissertations

Choosing a stationary phase is the first step in developing a liquid chromatography (LC) separation method, where the selectivity is governed by the differential interactions of the analytes with the stationary and mobile phases. Introducing a gradient in stationary phase functionality allows for tuning of analyte retention, translating to a possible improvement in selectivity and an increase in resolution versus that offered by uniform stationary phases.

In this work, C₁₈-silica, phenylbutyl-silica, and phenylbutyl-ammonium opposed continuous stationary phase gradients were fabricated using controlled rate infusion (CRI) on particle packed LC columns. Characterization of the stationary phase was carried out …

Biometal-Induced Structural Consequences Of Α-Synuclein – The Parkinson’S Disease Protein, Dinendra L. Abeyawardhane

Theses and Dissertations

The pre-synaptic protein α-Synuclein (αS) is often linked to the pathology of Parkinson’s disease (PD), an age-related neurodegenerative disorder. Lewy bodies, the cytopathological hallmarks of PD, are found to be rich in aggregates of misfolded αS protein. Metal dyshomeostasis has also been linked to PD due to the accumulation of iron in the substantia nigra pars compacta, and diminished copper levels reported in this same region. Metal dyshomeostasis in the brain coupled with oxidative stress can enhance the aggregation of αS. Recently, it was confirmed that mammalian αS is universally acetylated at the N-terminus, a common post-translational modification in …

Effects Of The Self- Determined Learning Model Of Instruction On Goal Attainment And Self-Determination For Students With Autism Spectrum Disorder., Meredith M. Moates

Theses and Dissertations

Even with current transition practice and service delivery requirements mandated for students with disabilities by the Individuals with Disabilities Education Act (IDEA, 2004) participation in postsecondary education and employment for individuals with autism remains low (Shattuck et al., 2012; Newman, Wagner, Cameto, & Knokey, 2011). The purpose of this study was to determine the effects of the Self-Determined Learning Model of Instruction (SDLMI; Wehmeyer, Palmer, Agran, Mithaug, & Martin, 2000). The intervention was designed to facilitate student development, and participation in community college course settings, increase academic and vocational goal attainment and self-determined behavior while decreasing support needs. The SDLMI …

The Development Of Intrinsically Cell-Permeable Peptide Libraries Using Mrna Display, Nicolas A. Abrigo

Theses and Dissertations

Peptides are emerging as promising therapeutics due to their inhibitory affinity towards protein-protein interactions (PPI). However, peptides have been limited mainly by their poor bio-stability and lack of cell permeability. Efforts to generate drug-like peptides have led to the development of macrocyclic peptides, which exhibit improved stability. Yet, most macrocyclic peptides still require the assistance of a cell penetrating peptide (CPP) for cellular entry.

High throughput technologies have been exceptional tools for the discovery of peptides to interrupt PPIs. This work details the recent advancements we have made to improve our high throughput technique, mRNA display, to yield more therapeutically …

An Investigation Of Neurological Soft Signs As A Discriminating Factor Between Veterans With Post-Traumatic Stress Disorder, Mild Traumatic Brain Injury, And Co-Occurring Post-Traumatic Stress Disorder And Mild Traumatic Brain Injury, David J. Rothman

Theses and Dissertations

While multiple Operation Enduring Freedom/Operation Iraqi Freedom/Operation New Dawn veterans suffer from mild Traumatic Brain Injury (mTBI), Post-traumatic Stress Disorder (PTSD), and co-morbid mTBI and PTSD, there remains difficulty disentangling the specific symptoms associated with each disorder using self-report and neurocognitive assessments. We propose that neurological soft signs (NSS), which are tasks associated with general neurologic compromise, may prove useful in this regard. Based on our review of the literature we hypothesized that individuals with PTSD would present with a greater number of NSS than controls or individuals with mTBI. Further, we hypothesized a synergistic effect, such that individuals with …

The Effect Of Music Characteristics On The Novelty And Usefulness Of Creative Ideas., Kathleen Keeler

Theses and Dissertations

This study explores the relationship between music and creativity. Prior research has conflicting results with some finding that music does influence creativity and some reporting no relationship and others finding that music is harmful to creativity. All of these studies, however, have largely focused on the presence vs. absence of music without consideration for the characteristics (i.e., musical key, tempo, etc.) that make up the sound we identify as music and their unique effects on us emotionally, physically, and cognitively. This dissertation contends that different characteristics of music influence different components of creativity (i.e., novelty and usefulness) through their effects …

Long-Term Effects Of Notch1 Signaling On Neural Stem Cells Following Traumatic Brain Injury, Cruz Sevilla Jr

Theses and Dissertations

Traumatic brain injury (TBI) is a devastating problem which stands as a leading cause of death and disability. The elderly is significantly affected by TBI, typically as the result of falls, and recovery is especially limited. This, in part, is associated with decreased tissue-specific stem cell regeneration and replacement of damaged cells in the aged brain. The diminished ability of the aged brain to recover is especially devastating after TBI, likely leading to permanent loss of sensory, motor, and cognitive functions. Studies have shown that the mature mammalian brain contains Neural Stem Cells (NSCs), found in specific regions of the …

The Analgesic-Like Properties Of Alcohol In Animal Models Of Chronic Pain, Bradley Neddenriep

Theses and Dissertations

Chronic pain and excessive alcohol consumption are individually problems in our society today. Alcohol Use Disorder (AUD) affects 15.1 million adult Americans each year. Chronic pain affects over 100 million people annually in the United States. However, there is growing evidence suggesting that these two conditions can often be interrelated with chronic pain increasing consumption of alcohol, and excessive alcohol consumption increasing pain that leaves a feedback cycle trapping millions of patients in an ever worsening spiral. Large population-based studies show an association between pain and alcohol abuse, suggesting a link between increased alcohol use and reduced pain. While rodent …

Untitled Unknown, Taylor Simone Stewart

Theses and Dissertations

This article is the first of a series exploring domination culture through the ways narrative has been indoctrinated as reality and weaponized as a holding cell for captives. Within this exploration, the narrative of domination is placed in relation to higher dimensional realms of the unknown; this being the before and after of domination culture. This positioning will allow for the reality of a simultaneous existence within the labyrinth of domination and a higher dimensional unknown to be framed. Within this series of articles, I question the roll of the rogue characters shamanistic agents of resisting domination, the fear of …

Nigga Is Historical: This Is Not An Invitation For White People To Say Nigga, Sandy Williams Iv

Theses and Dissertations

Over the past several years I have been on a quest to locate a world beyond the one I’ve been presented. I am interested in the history of atomic particles - like everything that radiates off of a monument (both literally and those things that are metaphorically reified) - invisible things, and the ways in which these things insect beyond our knowledge systems. This inquiry takes many forms. Mine is a conceptually based practice linked to record keeping and time, and the ways in which these concepts find plurality within our culture; or more pointedly, the importance that we attach …
