Hopeless Heartland: Space And Labor In Virginia, Katrina Hamilton

Theses and Dissertations

In the US, labor market conditions vary by demographics and space. Though space has been shown to be highly related to labor force outcomes, lower-level analyses are under-utilized as statistical workforce analyses tend to rely on national or state-level data. This study addresses variability in labor markets by taking a spatial approach, using cluster analysis and logistic regression to explore variations in labor market variables across census tracts in Virginia. Cluster analysis reveals several hot and cold spots of key labor market indicators: rates of marriage, poverty, educational attainment, and income. In many cases, poor social conditions, such as low …

Martian Mother, Elizabeth Mcgrady

Theses and Dissertations

This paper examines the relationship between humans and land, through the lens of the scientific and religious, bridging the physical realm with the spiritual. It acts as accompanying material to the project titled Martian Mother, supplementary information to the visual work, and an extension of the proposal, the center of the work. The proposal exists to send myself, or a like-minded individual, to Mars with artificial insemination equipment to give birth to the first Martian, becoming the first Martian Mother. This work is rooted firmly in speculative fiction, creating a nonlinear future framework for a new society and space exploration.

Spit In My Mouth: Queer Intimacies, Material Intra-Actions, And Sensuous Becoming, Gm Keaton

Theses and Dissertations

This document describes my multidisciplinary art practice as it intersects with New Materialism, Queer and Affect theory, Ecology, and my embodied and experiential knowledge as a queer subject. The writing is divided into two categories. One is more theoretical, thinking through these different discourses. The other realizes them through relationships and intra-actions between my material kin and me. With these two modes of writing,I propose that embodied and felt knowing is as valid and illuminating as more traditional forms of knowledge. These sections are interdependent and resist linear logic, offering relational meanings to each reader as they find their way …

Prey Begins With Play, Seren C. Moran

Theses and Dissertations

My work examines the lasting psychological and emotional torment of trauma focusing on sexual violence against women. My thesis consists of five short animated films recounting non-fiction experiences of sexual assault. To contextualize my work within cultural and historical representations of sexual violence, this text reflects my research on the mishandling of rape in Western art history as well as contemporary politics and cinema. In both my work and research, I address the complicated, and often contradictory, internal reality of experiencing and remembering trauma and how this relates to artistic strategies such as collage and maximalism. My personal struggles recovering …

Is Direct Transport To A Level I Trauma Center Associated With Better Outcomes In Patients With Traumatic Brain Injury Compared To Patients That Are Transferred To Trauma Level I From Other Hospitals, Narad Mishra

Theses and Dissertations

Transferring patients with traumatic brain injury (TBI) to trauma level I hospital from other lower level hospitals has been shown to increase the mortality compared to when patients are directly transported to trauma centers. Despite the results from studies and the field triage recommendation of transporting the TBI patients to trauma center, nearly half of the TBI cases are transported to other hospitals before transferring to the trauma center. A retrospective analysis of patients with TBI in the state of Virginia was carried out to access if direct transport of patients with TBI to trauma center improves the outcome compare …

A Qualitative Analysis Of Caregiver Goals For Urban Children With And Without Asthma, Megan M. Carlson

Theses and Dissertations

Pediatric asthma is a major public health concern that disproportionately affects children of color and youth living in low-income, urban areas. The implications for public health, child health, and family functioning necessitates our understanding and addressing experiences by families who are facing barriers within their socio-demographic context in addition to the stressors associated with managing pediatric asthma. The current study applied qualitative methods to interviews with caregivers of children with and without asthma in an effort to more deeply connect with caregivers’ experiences and yield richer information about the intersection of identities as Black caregivers living in an urban setting …

Predators And Principles: Think Tank Influence, Media Visibility, And Political Partisanship, Timothy Beryl Bland

Theses and Dissertations

By some measures, the major U.S. political parties have become more extreme in their political positions in recent decades, and scholars have raised concerns about whether the policy expertise provided by today’s think tanks has become similarly partisan and polarized. Furthermore, there is a perception that certain overtly partisan and highly visible think tanks wield considerable and growing influence over the policy platforms of the major U.S. parties, using their media presence to shape public and policymaker views of particular issues. Using publicly accessible tax, media, and congressional data, my proposed study assesses the extent to which media visibility and …

A Meta-Analysis Investigating The Correlation Between Treatment Integrity And Youth Client Outcomes, Ruben G. Martinez

Theses and Dissertations

Objective: The relation between treatment integrity and youth client outcomes in psychosocial treatment research has implications for therapist training, study design, and study interpretation. Despite work done in this area, this relation remains unclear. The aim of the current study was to meta-analyze and describe characteristics of investigations of integrity and outcome in youth.

Method and Analytic Plan: A total of N = 30 studies were identified. Conceptual and methodological factors were coded. Pearson’s r represented the magnitude of the integrity-outcome correlation. Robust variance estimation was used to account for dependency of within-study effect sizes. Two models were run with …

How Many Licks, Ashley Goodwin

Theses and Dissertations

Arts communities are currently reevaluating and restructuring power dynamics within their systems to accommodate a broader range of experience and subjectivity. However, the forces of control are still largely dictated by a broader patriarchal culture. This complicated, tangled dynamic is the focus of my research. Female artists who make work about men or about patriarchy more generally, are consistently subjected to its influence as the dominant cultural experience—the invisible “truth” that everything either is, or acts in reaction to its position. In reality, patriarchy is no longer gender specific. I will be addressing my relationship to it as well as …

Signaling Mechanism Responsible For 5-Ht2a Receptor Tolerance To Psychedelic Induced Head-Twitch Behavior In Mice, Audrey R. Mcmurtrie

Theses and Dissertations

In recent years, there has been a growing interest in psychedelic compounds stemming from their promising use as therapeutic agents and research tools that can be used to treat and study several neuropsychiatric disorders. Psychedelics have proven useful in a broad range of these diseases - they serve as models for psychosis in schizophrenia but have also had promising results in treating major depressive disorder, anxiety, and other common disorders. Decreased stigmatization surrounding psychedelics has further increased their use in research and clinical settings. In light of these trends and the promising nature of their use, a thorough understanding of …

Psychological Effects Of Reading: The Role Of Nostalgia In Re-Reading Favorite Books, Margaret A. Kneuer

Theses and Dissertations

There are many positive outcomes from feeling nostalgic, including reductions in loneliness and greater meaning and social connectedness. My primary research goal was to investigate whether I could trigger feelings of nostalgia from re-reading an old favorite book, and whether this elicited nostalgia would increase feelings of connectedness and meaning in life and reduce loneliness. I designed a two-study package (one correlational study and one experiment) to assess re-reading novels. Trait nostalgia was positively associated with enjoyment of re-reading books (Study 1). Re-reading a favorite novel, relative to reading a new novel or a set of newspaper articles, elicited nostalgia. …

A Microlongitudinal Study Of Menopause Symptoms And Problematic Eating In Midlife Women, Dana R. Schreiber

Theses and Dissertations

Women in midlife are at risk for engagement in problematic eating behavior which is associated with negative mental and physical health outcomes. Despite this risk, little is known about precipitating factors that may increase risk in this population. One specific, yet unstudied, factor that may increase risk for problematic eating in midlife women is menopause, which is characterized by distinct symptomatology (e.g., vasomotor symptoms, negative mood, sleep). The purpose of the current study was to investigate the associations among psychological, behavioral, and social symptoms of menopause and problematic eating behavior in midlife women using both retrospective and prospective methodologies. As …

An Integrated Exploration Of The Contextual, Relational, And Individual Factors That Impact High School Completion Among African Americans, Lesley B. Winchester

Theses and Dissertations

African American students are consistently reported as having among the lowest high school graduation rates when compared to other races (U.S. Department of Education, 2018). While many studies have sought to explore the potential risks of high school dropout, the intention of this study is to examine the factors that support the exemplary resilience of those students who do complete high school. The present study adopts the framework of García Coll et al.’s, (1996) integrative model of developmental competencies in minority children, as it seeks to identity whether and how contextual (spiritual, educational, cultural); relational (caregiver psychological and physical …

Mef2-Bound Genes May Influence Ethanol Sedation In Drosophila Melanogaster, Katlyn M. Myers

Theses and Dissertations

Alcohol Use Disorder (AUD) is a global health issue that affects millions of people every year. This disorder has serious negative mental and physical consequences. Currently, treatment options for this disorder are largely limited to psychological therapy, with very few medications available to treat it. Being able to identify the environmental and genetic components that influence AUD can help improve diagnosis and treatment options. Previous studies in humans have shown a link between initial sensitivity and risk for alcohol abuse. Our laboratory uses Drosophila melanogaster as a model to study the genetic and environmental components of alcohol-related behaviors. Previous lab …

Estimating Response Status In Sequential Multiple Assignment (Smar)-Like Trials, Keighly Bradbrook

Theses and Dissertations

Sequential, multiple assignment, randomized trials (SMARTs) allow investigators to develop and compare experimental treatment regimens in which individuals are successively randomized to different treatments based on some set of predetermined rules. The rules used to make decisions on when and how to switch treatments are based on a chosen set of tailoring variables. Although not always true, intermediate response is commonly used as the primary tailoring variable as it is often predictive of future treatment success. As such, successful implementation depends on identifying patients who respond to treatment, though in some situations such mechanisms may not exist. Further, patient-level covariates …

Examining The Role Of Racial Discrimination In Obesity Treatment Disparities Among African American Emerging Adult Women, Kristal Brown

Theses and Dissertations

The overarching goal of the proposed work was to examine how racial discrimination contributes to disparities in adiposity and treatment response between non-Hispanic Black and non-Hispanic White emerging adult women, and to identify potential protective and risk factors that might moderate this association—all in service of improving lifestyle interventions for this high-risk population. Project aims were achieved across three studies. In Study 1, we extracted data for emerging adults (N=261, BMI=33.8+4.9 kg/m², age=21.9+2.1 years) who recently completed a BWL program adapted specifically for emerging adults and compared treatment outcomes for non-Hispanic White and non-Hispanic Black women. In Study …

Flexible Methods For Accounting For Distributional Misspecification Of The Response-Adaptive Randomization Ratio In Two-Arm Clinical Trials With Continuous Or Survival Outcomes, Victoria C. Garcia

Theses and Dissertations

Optimal response-adaptive randomization (RAR) is used in clinical trials (CTs) to balance ethics and power by randomizing patients according to the unknown population parameters of an assumed parametric response distribution selected prior to data collection. If the distribution of the observed response data is misspecified, the resulting randomization may produce unanticipated trial characteristics. This dissertation introduces flexible estimators of the optimal RAR ratio that adjust for such misspecification.

When observed response data were continuous in nature, sample moments were estimated from a continuous fit of the empirical CDF. These sample moments then served as the operands for the first flexible …

Bee Diversity Of Three Appalachian Shale Barren Sites, Olivia C. Latham

Theses and Dissertations

Insect pollination is vital to ecosystem function. However, climate change, habitat loss, pesticides, and a variety of other anthropogenic sources are contributing to a decline in pollinator diversity. Fragile small ecosystems with a high composition of specialized plant species that rely on specific pollinators such as Appalachian shale barrens, are especially at risk of losing biodiversity. This study combines the use of active sweep net sampling of endemic shale barren forbs and passive trap methods over the course of a bloom season (April-August) in three barren sites to identify bee community populations and visitation relationships between pollinator species and endemic …

Integration Of Multi-Omic Platforms To Understand The Regulation Of Genes In Human Disease, Eva Lancaster

Theses and Dissertations

Epigenetic mechanisms have been hypothesized to modify gene expression (GE) in response to both genetic variation and environmental exposures, ultimately contributing to the development of complex traits. Epigenome-wide association studies (EWAS) aim to test the theory that marks of DNA methylation (DNAm) have downstream consequences that result in the development of complex diseases. Although these methods have been successful in identifying DNAm patterns in complex traits, specific molecular mechanisms involved in the etiology of complex diseases remain unidentified. This knowledge gap does not originate from a lack of DNAm-trait associations, but rather stems from study design issues that affect the …

The Impact Of The Fda Warning On Post-Tonsillectomy Opioid Prescribing In Publicly And Privately Insured Children, Dianna J. Soelberg

Theses and Dissertations

Due to reports of significant adverse events, the U.S. FDA placed a Boxed Warning on the opioid codeine in February 2013 – contraindicating its use in pediatric patients undergoing tonsillectomy and/or adenoidectomy. Studies conducted in privately insured children showed a reduction in codeine prescribing and a slight increase in alterative opioid prescribing following the FDA warning, yet the extent to which the FDA warning impacted prescribing in publicly insured children is unknown. Using a quasi-experimental interrupted time series design, this study evaluated codeine and alternative opioid prescribing before and after the FDA warning in both publicly and privately insured children …

Knowledge And Skill Predictors Of Voice Behavior: Voice As An Upward Influence, Zitong Sheng

Theses and Dissertations

Abstract

In recent years, there has been a growing body of research focused on improving our understanding of employee voice behavior. Yet this literature focuses mainly on factors that influence employees’ decisions regarding whether to speak up (i.e., quantity of voice behavior), rather than factors that influence whether voice behavior turns out to be effective. As a result, job attitudes and personality characteristics have been identified as the major personal factors predicting voice behavior. The current study contributes to the voice literature by viewing voice from an upward influence angle, examining the influences of the quality of content and …

The Impact Of Occupational Therapy Acute Care Services On Readmission Rates For Patients In Medicare’S Hospital Readmission Reduction Program, Jessica M. Edelstein

Theses and Dissertations

The United States (US) health care system is faced with the daunting challenge to make healthcare payments commensurate with quality of care provided. To assess quality, metrics for reimbursement have been established by Medicare. One such quality metric is hospital readmissions (readmissions). Readmissions are associated with poor patient outcomes and costly. Associated poor patient outcomes include higher risk for mortality, deconditioning, nutritional issues and cognitive impairments. As a result, readmissions cost Medicare $26 billion annually. Current strategies for reducing readmissions in the US are fragmented and hospital-specific. While specific strategies may vary, hospitals that have low readmissions rates tend to …

A Comparison Of Computer- And Interviewer-Administered Measures To Identify Heavy/Problem Alcohol And Other Drug Use In Primary Care Patients, David J. Pomm

Theses and Dissertations

Substance use is a leading cause of morbidity and mortality that is under-identified in primary care settings. Screening for substance use in primary care requires an efficient and accurate approach. Exploring methods to collect sensitive and accurate data about substance use and related problems is important to inform research practice and clinical care. Using RCT data comparing computerized and therapist delivered brief intervention for substance use problems, the present study had a unique opportunity to compare computerized anonymous and confidential surveys to a confidential, interviewer-administered assessment in a sample of N = 540 males and females at risk for heavy/problem …

Black Women And Body Image: Implications Of The Racialized Beauty Aesthetic, Rachel L. Boutte

Theses and Dissertations

Black women have the highest prevalence of overweight and obesity relative to any other demographic group in the United States, however current weight management interventions appear least effective for them. Although several hypotheses have been proposed to explain these outcomes, few studies have collected data to evaluate how well they fit the lived experiences of Black women. In particular, the potential roles of body image and body dissatisfaction in the development and maintenance of overweight and obesity in Black women are not well understood. Extant literature largely reports that Black women are inoculated from body dissatisfaction due to cultural factors, …

Design Hub: Activating Community By Design, Ed Williams

Theses and Dissertations

MOTIVATION

At the turn of the century, Robert Putnam (2000, 27) wrote “...a powerful tide bore Americans into ever deeper engagement in the life of their communities, but a few decades ago that tide reversed and we were overtaken by a treacherous rip current.” Putnam is describing a loss of “social capital” throughout American society. Research suggests that many of our contemporary issues are the result of a decline in “social capital,” or “community.”

This pervasive lack of community is thought to be detrimental to “educational performance, safe neighborhoods, equitable tax collection, democratic responsiveness, everyday honesty, and even our health …

Adverse Childhood Experiences In Children Presenting To Integrated Pediatric Primary Care, Irene A. Jacobs

Theses and Dissertations

The prevalence of adverse childhood experiences (ACEs) has created a significant public health concern in the United States. A vast body of literature examining adult populations has displayed a dose-response association between cumulative ACEs and chronic illnesses (Chapman et al., 2004; Felitti et al., 1998). ACEs research conducted with children and adolescents has indicated higher ACE scores associated with learning and behavioral problems (Burke et al., 2011), health risk behaviors (Garrido et al., 2018), and mental health challenges (Mackner et al., 1997). However, ACEs research and subsequent interventions have largely relied upon retrospective data retrieved from adults (Felitti et al., …

Competing Models Of Exposure To Community Violence Among Urban Youth: Dimensional Versus Person-Centered Approaches, Sarah K. Pittman

Theses and Dissertations

Exposure to community violence is prevalent among urban youth residing in neighborhoods with high rates of crime and violence. Although there is strong evidence suggesting that community violence exposure is associated with negative consequences on youth development, there are inconsistencies in theories and evidence regarding the nature of these associations. Methodological limitations of dimensional approaches to conceptualizing exposure, including the assumption that adolescents are similar in their frequency and patterns of exposure, likely contribute to the inconsistencies in findings of associations. Recently, person-centered methods have been used to elucidate associations between community violence exposure and consequences on adolescent development. However, …

Effects Of A Self-Advocacy Intervention On The Abilities Of College Students With Intellectual And Developmental Disabilities To Request Academic Accommodations, Katherine R. Brendli

Theses and Dissertations

Students with intellectual and developmental disabilities (IDD) are pursuing college at higher rates than ever before. However, many of these students experience barriers to success in college and need to self-advocate for their needs, such as requesting academic accommodations. This study examined the effects of a virtually delivered self-advocacy intervention package on the abilities of college students with IDD to request their academic accommodations. This is the first study to virtually implement a modified version of the Self-Advocacy and Conflict Resolution strategy with college students with IDD. Using a single-subject multiple-probe across participants design, this study was implemented with three …

Separate And Unequal: Latinx Access, Enrollment And Completion Of Ap Coursework In The State Of Virginia, Virginia Elizabeth Palencia

Theses and Dissertations

In response to the national problem of overrepresentation of Latinx students in general education classes, this study addresses Latinx access to Advanced Placement (AP) coursework, enrollment, and completion patterns in Virginia, a growing destination state for many Latinx families and students. Through a secondary data analysis of both the Civil Rights Data Collection (2015-6) and College Board data (2016), this quantitative study mapped patterns of disproportionality in AP access, enrollment, and completion for Latinx students, who comprise 13% of enrollment in Virginia public high schools. In addition, a case study of two diverse school districts provides evidence of segregation and …
