Articulating The Heart Of Darkness: A Psychometric And Behavioral Analysis Of The Relationship Between Psychopathy And Sadism, Emily Lasko

Theses and Dissertations

Psychopathy and sadism, personality constructs largely characterized by antagonistic tendencies, share several similar traits and behaviors such as cruelty, callousness, and antisocial behavior. Due to this overlap, it remains unclear whether sadism is simply a facet of psychopathy, or they represent distinct but related constructs. The degree of overlap and distinction between these traits has yet to be empirically and thoroughly examined; therefore, the present project had two overarching interconnected aims: 1) Investigate the degree of psychometric overlap between psychopathy and sadism, and 2) examine potential behavioral distinctions between psychopathy and sadism. In Study 1, participants completed an online battery …

Grief, Loss, And Climate Change: Validation Of A Solastalgia Scale, Claire Luce

Theses and Dissertations

Climate change has been identified as a defining issue of this century (United Nations, n.d.). Climate change impacts human wellbeing including mental health. While much research has focused on the way that the effects of climate change cause increases in common mental disorders, mental health is not just the absence of these disorders (World Health Organization, 2014). Non-pathologized mental health responses to climate change, such as the grief and loss that results from climate change impacts, are a growing consideration for researchers. Solastalgia, or the distress experienced in the absence of the solace once provided by the environment in the …

Theorizing #Girlboss Culture: Mediated Neoliberal Feminisms From Influencers To Multi-Level Marketing Schemes, Frankie Mastrangelo

Theses and Dissertations

I define girlboss feminism as emergent, mediated formations of neoliberal feminism that equate feminist empowerment with financial success, market competition, individualized work-life balance, and curated digital and physical presences driven by self-monetization. I look toward how the mediation of girlboss feminism utilizes branded and affective engagements with representational politics, discourses of authenticity and rebellion, as well as meritocratic aspiration to promote cultural interest in conceptualizing feminism in ways that are divorced from collective, intersectional struggle. I question the stakes involved in reducing feminist interrogations and commitments to discourses of representation, visibility, and meritocracy. I argue that while girlboss feminism may …

Nature-Inspired Material Strategies Towards Functional Devices, Sayantan Pradhan

Theses and Dissertations

Naturally sourced, renewable biomaterials possess outstanding advantages for a multitude of biomedical applications owing to their biodegradability, biocompatibility, and excellent mechanical properties. Of interest in this dissertation are silk (protein) and chitin (polysaccharide) biopolymers for the fabrication of functional biodevices. One of the major challenges restricting these materials beyond their traditional usage as passive substrate materials is the ability to combine them with high-resolution fabrication techniques. Initial research work is directed towards the fabrication of micropatterned, flexible 2D substrates of silk fibroin and chitin using bench-top photolithographic techniques. Research is focused on imparting electrochemical properties to silk proteins using conducting …

Inclusive Academic Education & Vocationally-Oriented Transition Predictors’ Association With Post-Secondary Outcomes Of Youth With Intellectual And Developmental Disabilities, Joshua P. Taylor

Theses and Dissertations

Despite efforts through legislation to increase the engagement of individuals with intellectual and developmental disabilities (IDD) in competitive integrated employment (CIE) and post-secondary education, outcomes remain poor. However, recent policy has emphasized CIE as a preferred outcome and created new opportunities to engage individuals with IDD in post-secondary education. Likewise, research into the transition of youth with disabilities has revealed several predictors of post-school success including inclusive education and a variety of vocationally-oriented experiences. Previous research had not determined whether students with IDD received both inclusive academic education and vocational transition experiences or how these predictors might interact. The purpose …

Interventions To Slums And Informal Settlements: A Case Study Of The Integrated Housing Development Program In Addis Ababa, Ethiopia, Nathan Teklemariam

Theses and Dissertations

Rapid urbanization is currently taking place in developing regions that have yet to address already existing and persistent inequities within their urban centers. There is perhaps no urban policy issue more critical for governments of the global South than the elimination of slums and informal settlements, along with the development of equitable access to affordable housing for low-income residents. Ethiopia has taken on this challenge through its Integrated Housing Development Program (IHDP), which incorporates slum clearance and resettlement through a government-led development of condominium housing targeting those displaced and other low and middle-income residents in the city.

Since the launch …

Expand Your Horizon: Investigating An Online Intervention For Weight Bias Internalization, Alexandria Davies

Theses and Dissertations

Weight bias internalization (WBI; i.e., self-directed weight stigma or the degree to which individuals apply negative weight-based stereotypes to themselves), is problematic because it is associated with increased stress, emotional eating, healthcare avoidance, and exercise avoidance. Thus, WBI exacerbates health disparities and there is an urgent need to create treatments that address this concern. The current study examined the preliminary effectiveness of a previously developed online body gratitude journaling intervention (i.e., Expand Your Horizon) compared to an active control writing condition in emerging adult women with WBI. Racially/ethnically diverse women (N=100; n=49) or Expand Your Horizon ( …

Third Culture Kids - Playing To Heal, Amna Sana

Theses and Dissertations

With increased globalization and a large expat population, Qatar is home to increasing numbers of Third Culture Kids (TCKs). TCKs are children who live in a country where their parents are non-native, children who grow up between cultures. Young TCKs, especially children between the ages of three and seven, do not possess the skills to adequately vocalize their feelings, but fortunately, play therapy allows them to articulate problems and feelings on their own terms. This thesis addresses the emotional hurdles facing TCKs, using concepts derived from play therapy and offering a series of interactive objects designed to reflect emotional expression …

Form Follows Culture, Nada Raafat Elkharashi

Theses and Dissertations

We all use everyday objects as part of our daily routines, but the way we use them varies from one culture to another. Using George Herbert Mead’s study of human conduct and Louis H. Sullivan’s credo, “Form follows function,” this thesis examines the cultural meanings and implications surrounding the fundamental act of drinking water. Using a methodology of iterative, exploratory making, a collection of glass vessels explores philosophical and physical manifestations of Islamic cultural principles derived from the Sunnah of Prophet Muhammad صلى الله عليه وسلم. With the goal of restoring cultural integrity to our daily activities, the work highlights …

Western Clinicians’ Diagnostic Accuracy Of Culture-Bound Syndromes, Lisa Y. Chung

Theses and Dissertations

Culture-bound syndromes are of increasing importance in today’s more diverse world. The current study measured the ability of clinicians trained in a western setting to accurately diagnose culture-bound syndromes from cultures outside of their background. Eight-four clinicians were recruited through the American Psychological Association (APA) membership directory. All recruited clinicians were asked to read three vignettes. In two vignettes a patient was suffering from either Hwabyung or Ataque de Nervios and the third vignette represented a control GAD vignette. The clinicians were asked to diagnose the patient in the vignette, to explain what information informed their diagnosis, to complete two …

Floating Home: An Imagined Community, Carrie Collier

Theses and Dissertations

Climate experts around the world agree that anthropogenic climate change threatens the long-term survival of the human species. Human activity has already contributed to an exponential spike in the rate of extinction among other Earthly species, beginning at the time of the industrial revolution.

The American home is a site of concentrated resource consumption, waste production, and greenhouse gas emission. It is also a site where gender-based expectations continue to burden women with a majority share of uncompensated, under-valued domestic labor. Collective or communal housing arrangements could reduce per capita carbon output while facilitating the equitable re-distribution of work that …

THE TRIFECTA OF TRANSFORMATIONAL CHANGE IN HEALTHCARE DESIGN

Flourish: Combating Food Insecurity & Promoting Wellness On A College Campus, Jocelyn Zavala

Theses and Dissertations

MOTIVATION In the past, it has been assumed that students enrolled in college are fairly privileged individuals unlikely to face challenges associated with poverty (Haskett et al., 2020). That assumption has been challenged in the past few decades and a survey released last year by the Hope Center for College, Community and Justice indicated that 45% of today’s higher education students face food insecurity (Goldrick-Rab et al., 2019). According to VCU’s Dean of Students Office, it is a situation in which a student lacks access to enough nutritious food in order to live a healthy, active life. Food insecurity can …

Improving Patient-Specific Assessments Of Regional Aortic Mechanics Via Quantitative Magnetic Resonance Imaging With Early Applications In Patients At Elevated Risk For Thoracic Aortopathy, Patrick A. Jones

Theses and Dissertations

Unstable aortic aneurysms and dissections are serious cardiovascular conditions associated with high mortality. The current gold standards for assessment of stability, however, rely on simple geometric measurements, like cross-sectional area or increased diameter between follow-up scans, and fail to incorporate information about underlying aortic mechanics. Displacement encoding with stimulated echoes (DENSE) magnetic resonance imaging (MRI) has been used previously to determine heterogeneous circumferential strain patterns in the aortas of healthy volunteers. Here, I introduce technical improvements to DENSE aortic analysis and early pilot application in patients at higher risk for the development of aortopathies. Modifications to the DENSE aortic postprocessing …

Tya And Educational Outreach In Higher Education: An Asset To Undergraduates And Their Community, Emily J. Mattison

Theses and Dissertations

Undergraduate students pursuing a career in theatre are at the beginning of their life-long training and understanding and appreciation for the art. Performing in a Theatre for Young Audiences (TYA) touring production alongside the responsibility of crafting educational outreach opportunities provides the students with a unique chance to comprehend the art they have chosen to devote their lives to. This paper details the value of offering a course I crafted entitled “TYA Educational Outreach”, for both the undergraduates enrolled and the community they would be reaching. While undergraduates develop an understanding of the impact theatre can have on an individual …

Chains Of Stability: Building Financial And Cultural Community Sustainability For Latinas In Richmond & Chesterfield, Virginia, Gabriella C. Pino-Moreno, Gabriella Pino-Moreno

Theses and Dissertations

As the Latinx population in the US continues to grow, new Latin-centric ethnic enclaves are developing in urban areas, including those in US southern states. While there has been some discourse on the role of Latin immigrants in the US labor market generally, there is limited literature addressing the specific experiences of Latinas as inhabitants of urban spaces and the factors impacting their economic sustainability. Latinas, on average, earn $0.54 to every $1.00 a white male earns. Their economic position, combined with their cultural traditions and practices, raises questions about how they achieve economic security in the US. This research …

The Student Experience Of Higher Education During The Covid-19 Pandemic: How Class And Race Shape Socially Distanced Learning At A Public University, Alice M. Quach

Theses and Dissertations

While prior research has examined trends toward growing uncertainty and precarity for young adults within the economy and higher education, the COVID-19 pandemic appears to be exacerbating these existing inequalities and risks. Drawing from 30 semi-structured in-depth interviews with college students at a large Southern and urban public university, this study examines how the COVID-19 pandemic is affecting students’ learning experiences, and how those experiences are differentially shaped, in turn, by their class and race. This exploratory research illuminates our understanding of the multiple mechanisms by which the COVID-19 pandemic is shaping existing inequalities in the higher education system, mostly …

Effects Of Buprenorphine Treatment On Myelin Following Traumatic Brain Injury In A Rat Model, Jane Ryu

Theses and Dissertations

Traumatic brain injury (TBI) is a common phenomenon, accounting for significant cost and adverse health effects. While there is information about focal pathologies following TBI, knowledge of more diffuse processes is lacking, particularly regarding how analgesics affect this pathology. As Buprenorphine (Bup) is the most commonly used analgesic in experimental TBI models, the current study investigated the effects of the opioid analgesic Buprenorphine-sustained release-Lab (Bup-SR-Lab) on physiology and myelin alterations at 1d and 4w following central fluid percussion injury (cFPI) in adult male rats. Microscopic assessments were performed at 1 day and 4w post-injury. Myelin pathology was assessed by evaluating …

Mechanistic Insights Of Mitochondrial Reactive Oxygen Species In Alzheimer's Disease Models, Jakob C. Green

Theses and Dissertations

Alzheimer’s disease (AD) is a neurodegenerative disease that results in impaired cognition, disorientation, confusion, poor judgement, and behavioral changes. The mitochondrial cascade hypothesis (MCH), which postulates that accumulating oxidative stress and mitochondrial dysfunction plays an integral role in the development of the disease, potentially upstream, in conjunction with or independent of Aβ and tau. The literature supports the critical role of mitochondrial dysfunction in the progression and development of AD, but is inconclusive about what precise role, as initiator or delegate, it performs. Regardless, the impact that oxidative stress and mitochondrial dysfunction have on AD deserves further study and investigation. …

A Multilevel Mixed Methods Examination Of Treatment Nonadherence Among Rural Cancer Survivors, Bonny Morris

Theses and Dissertations

While mortality rates have been decreasing over the last 40 years, cancer remains a leading cause of death in the United States. Over 1.7 million people were diagnosed with cancer in 2019, and there were more than 600,000 cancer deaths. Of the 15 million cancer survivors in the US, nearly 3 million reside in rural areas and experience 3% higher cancer incidence and 10% higher cancer mortality compared to their nonrural counterparts. During 2006-2015, the annual age-adjusted mortality rates for all cancer sites combined decreased at a slower pace in rural areas versus nonrural areas (-1.0% vs -1.6% per year, …

Parametric, Nonparametric, And Semiparametric Linear Regression In Classical And Bayesian Statistical Quality Control, Chelsea L. Jones

Theses and Dissertations

Statistical process control (SPC) is used in many fields to understand and monitor desired processes, such as manufacturing, public health, and network traffic. SPC is categorized into two phases; in Phase I historical data is used to inform parameter estimates for a statistical model and Phase II implements this statistical model to monitor a live ongoing process. Within both phases, profile monitoring is a method to understand the functional relationship between response and explanatory variables by estimating and tracking its parameters. In profile monitoring, control charts are often used as graphical tools to visually observe process behaviors. We construct a …

Medical Expenditures And Health Care Utilization: A Comparison Among U.S. Adult Tobacco Consumers (I.E. Never Tobacco Users, Cigarette Smokers And Smokeless Tobacco Users), Raheema S. Muhammad

Theses and Dissertations

Introduction

Cigarette smoking poses a great economic cost on the U.S. health care system by incurring high health care expenditure and health care utilization in the adult population. Although there is a sufficient amount of information on the health care cost associated with cigarette smoking there is a gap in how other forms of tobacco use may impact healthcare expenditures and utilization in comparison to cigarette smoking. The main objectives of this study were: 1) to estimate and compare health care expenditure and health care utilization across different tobacco use groups using nationally representative data 2) to estimate and compare …

Influence Of Immigration Status On The 10-Year Trajectories Of Psychosocial Functioning In Individuals With Traumatic Brain Injury, Chimdindu Ohayagha

Theses and Dissertations

The population of racially/ethnically diverse groups within the U.S. is growing at an exponential rate. The U.S. Census Bureau estimated the number of foreign-born individuals in the U.S. to be nearly 40 million or 13% of the total population (Grieco et al., 2012). Racially/ethnically diverse groups in the U.S. have a higher incidence of traumatic brain injury (TBI; Gary et al., 2009). Although racial/ethnic disparities have been documented in numerous outcomes, research has yet to thoroughly explore differences in rehabilitation outcomes for immigrants relative to U.S.-born individuals. The purpose of this study was to compare the functional and mental health …

Evolution And Clinical Relevance Of Vaginal Bifidobacterium Breve In The Vaginal Environment, Nicole R. Jimenez

Theses and Dissertations

The vaginal microbiome is important in reproductive health and disease and is often dominated by lactobacilli. However, there are many other community state types dominated by single species that are still not well characterized. Bifidobacterium species such as Bifidobacterium breve and Bifidobacterium longum have been observed to dominate vaginal profiles. Bifidobacteria are important in infant gut development, but little is known about their role in vaginal health. Thus, we sought to use a multisystem approach to better characterize Bifidobacterium species present in the vaginal microbiome with an emphasis on B. breve. Eight strains of B. breve were isolated from vaginal …

Reward-Related Effects Of Amphetamines Administered By Electronic Cigarette, Lucas Wohler

Theses and Dissertations

While e-cigarette vaporizers are primarily used for the delivery of nicotine, they can also be used to administer a wide range of other substances of abuse including stimulants such as d-amphetamine and methamphetamine. Methamphetamine and prescription amphetamines are widely abused throughout the United States and across the world leading us to believe there may be abuse potential with vaping methamphetamine as vaping becomes increasingly popular. In the present study, methamphetamine and amphetamine vapor were assessed using vapor capture methods. The vapor samples were then analyzed using liquid chromatography mass spectroscopy (LC-MS). Three experiments were carried out to examine the abuse …

The Role Of Insurance Coverage In Outpatient Substance Use Disorder Treatment Referral, Utilization, And Outcomes, Huyen Pham

Theses and Dissertations

Opioid-related overdoses increased dramatically in recent years. Medicaid plays a predominant role in paying for opioid use disorder (OUD) treatment. However, there is a critical gap in understanding the role of Medicaid coverage in referrals to treatment, treatment utilization, and treatment retention. The three studies used observational and quasi-experimental (i.e., natural experiment) designs leveraging state and year variation in Medicaid expansion to characterize the role of Medicaid coverage in OUD treatment. We found that individuals with OUD with Medicaid insurance were more likely to use outpatient treatment, whereas those who were uninsured were more likely to use self-help groups only. …
