The Relationships Between Adolescents’ Future Aspirations And Postsecondary Enrollment: Finite Mixture Models, Chu Yi Lu Qiu

Theses and Dissertations

This study took person-centered statistical approaches to explore the multidimensional construct of adolescents' future aspirations and its associations with three covariates (i.e., gender, race, and SES) and a binary, distal outcome measure, postsecondary enrollment. Fourteen survey items representing the multidimensionality of adolescents' future aspirations were extracted from two-waves of Educational Longitudinal Study:2002 student data. The multidimensionality or the latent construct of the adolescents' future aspirations were explored using two finite mixture models called latent class analysis (LCA) and latent transition analysis (LTA). Based on the students' response patterns on the fourteen indicators, three latent classes representing three levels of aspiration …

Beyond Black Or White: An Examination Of Intersectional Identities, Blame Attribution, And Sexual Violence, Ashlynn D. Bell

Theses and Dissertations

While there may be more discussions of sexual violence than there have been in previous years, cases continually arise where the responsibility of those who have been assaulted is called into question (Alaggia & Wang, 2020). Secondary victimization, or victim blaming, is partially responsible for the continued misattribution of responsibility to survivors. These perspectives minimize the experiences of survivors, which dissuades individuals from the reporting of perpetrators. The current study aimed to evaluate whether particular intersecting identities influenced perceptions of responsibility, in a hypothetical scenario depicting an assault. The race, gender identity, as well as perceptions of respectability of the …

Difficult Paintings, Hao (Damien) Ding

Theses and Dissertations

The sublime as a concept has a fraught and racist history. However, it remains the single most helpful idea in describing the deeply felt state of being when one comes across something ineffably powerful. From an art-making perspective, this thesis, and the accompanying exhibition of installations and paintings, proposes an alternative construction of the concept of the sublime. Using Lacanian psychoanalysis as a conceptual point of departure, a painter can manipulate the relationship of the viewer and paintings to create paradoxical moments of simultaneous intimacy and distance, which interact to create an alternative path towards the sublime. Through descriptions of …

Validation Of A Screening Tool For Pediatric Obstructive Sleep Apnea: A Pilot Study, Julia A. Giardina

Theses and Dissertations

Purpose: The purpose of this study was to evaluate the Pediatric-Modified-STOP-Bang (PM-STOP-Bang) as a screening tool to assess sleep related breathing disorders (SRBD) within a pediatric population. The specific aims of this study were: 1) compare the PM-STOP-Bang scores with those from the validated Pediatric Sleep Questionnaire (PSQ), 2) determine the ability of the PM-STOP-Bang and the PSQ screening tools to accurately detect children of high risk for SRBD from a one-night home sleep apnea test (HSAT).

Methods: Orthodontic patients were screened using the PM-STOP-Bang at VCU Graduate Clinic. Patients (n=10) who were recruited and enrolled. Five were determined to …

Modulation In Nmda Receptor Function Alleviates Safety Learning Deficit In Females Who Experienced Chronic Stress During Adolescence, Zuby C. Okafor

Theses and Dissertations

Anxiety disorders disproportionately impact women and are more prevalent in people with a history of chronic stress. Post-traumatic stress disorder (PTSD) is a type of stress and trauma-related disorder that is largely characterized by hyperarousal to fear-based cues. The inability to dissociate the fear-response from a non-threatening cue is known as impaired safety learning. Given that N-methyl-D-aspartate (NMDA) receptors are key mediators of learning behaviors, we examined the role of NMDAr function in deficient safety learning. Previous studies have shown that female rats with a history of stress have altered NMDAr gene expression and altered glutamatergic signaling; therefore, we hypothesized …

Opioid System's Involvement In Ketamine's Antidepressant-Like Effects, Fan Zhang

Theses and Dissertations

Depression is one of the most debilitating disorders in the world. The currently available medications typically have a 2-4 week delay in their therapeutic effects and are ineffective for about 40% of patients. In 2000, a subanesthetic dose (0.5 mg/kg i.e.) of the dissociative anesthetic ketamine was reported to have both rapid and robust antidepressant effects in in treatment-resistant depressed patients. However, the mechanisms responsible for ketamine’s antidepressant effects remain unclear. In 2018, a clinical study reported that pretreatment with the nonselective opioid antagonist naltrexone attenuated the rapid antidepressant effect of ketamine in depressed patients. The current study investigated the …

Untitled, Lihua Yu

Theses and Dissertations

The library stores up my favorite memories. Sometimes I look for a book by its title, author or publisher, sometimes by its designer; other times I just wander around different sections and enjoy encountering books by chance. As an object, a book is eternal while I am a passer-by. I believe in the connection between people who read the same books and watch same films with me. This untitled book is a thankful catalog, documented in a straightfoward way

Cognitive Debiasing Intervention For Assessment Of Prolonged Grief Disorder, Farah Aslanzadeh, M.S.

Theses and Dissertations

Cognitive debiasing is an approach to reducing diagnostic decision-making errors resulting from the misuse of cognitive heuristics and biases. This study built on prior research that has successfully used a multi-modal debiasing approach to reduce diagnostic errors. Clinicians were recruited and randomized into a general presentation on the changes in the stress and trauma section of ICD-11 (including the diagnostic criteria of prolonged grief disorder [PGD]) or the same general presentation plus and a cognitive debiasing intervention for PGD. All clinicians were then asked to diagnose three patient vignettes in which biases/potential decision-making errors were embedded in the text. Results …

A Mixed Methods Approach To Examine Racial Disparities In Adherence To Surveillance Mammography Among Breast Cancer Survivors, Megan C. Edmonds

Theses and Dissertations

PURPOSE: Annual surveillance mammography is a critical part of routine cancer care for breast cancer (BC) survivors; reducing mortality by 39%. However, disparities exist with regard to adherence to surveillance mammograms among BC survivors; Black women are 44% less likely to adhere than their White counterparts. Despite the existence of this racial disparity for over a decade, little is known about factors that explain reasons for Black BC survivors’ non-adherence. This is because most studies have not evaluated the role of healthcare delivery or psychosocial factors. Guided by the Behavioral Model for Vulnerable Populations, the purpose of this mixed methods …

A Non-Inferiority Randomized Controlled Trial Comparing Behavioral Sleep Interventions In Women Veterans: A Secondary Analysis Of Pain Outcomes, Scott Ravyts

Theses and Dissertations

Women are disproportionally more likely to experience both insomnia and chronic pain. While these two conditions frequently co-occur, a wealth of literature suggests that insomnia is a stronger predictor of pain than pain is of insomnia. Preliminary research indicates that sleep apnea may also lead to adverse pain outcomes, with the combination of insomnia and sleep apnea contributing to an adverse synergistic effect on pain. Despite the clinical implications of such findings, knowledge regarding the interrelations between sleep disorder complexity and pain remain limited, especially among women. Additionally, interventions seeking to improve pain by targeting insomnia have yielded inconsistent results …

Math Leaders’ Perceptions Of Social Justice Pedagogy: Implications For Professional Development On Teaching Mathematics For Climate And Environmental Justice, Angela M. Allen

Theses and Dissertations

Two significant crises facing communities of color are climate and environmental injustices (Schlosberg & Collins, 2014) and the achievement gap in standardized test performance as an impact of inequitable educational experiences rooted in a history of social inequities (Agarwal, 2011; Milner, 2020). Previous studies on teaching mathematics for social justice demonstrate positive student outcomes from this practice (Berry, 2008; Gutstein, 2006). Existing literature also points to benefits when focusing on a specific social justice topic during mathematics instruction (Bartell, 2013; Stocker, 2012). However, few studies focus on math leaders’ perceptions of teaching mathematics for climate and environmental justice (TMCEJ).

Genetics And Alcohol Interventions In Youth, Zoe E. Neale

Theses and Dissertations

Alcohol is the most commonly used substance among youth, and risky alcohol use is associated with harmful consequences such as accidents, academic consequences, and physical and emotional health problems. Alcohol use disorders are approximately 50% heritable, yet most efforts to prevent and intervene upon youth alcohol use focus only on environmental factors. Furthermore, current prevention and intervention programs tend to have modest effects and are not uniformly effective for all individuals. Gene-by-intervention (GxI) studies offer an opportunity to expand current understanding of interventions by examining whether underlying genetic risk may contribute to differential program effects. Much of the current GxI …

Owning Our Story: An Interior Exploration To Foster Self-Reflection, Hannah Bulow

Theses and Dissertations

With emerging technologies in the 21st century, Millennial and Gen Z adults have a complicated relationship with these new technologies when it comes to creating and sustaining personal relationships (Dalessandro, 2018). When persons aged 18-35 forged new relationships without the presence of technology, relationships were more organic, natural, and led to less conflicts. Neuroimaging of the brain has also shown that neurocognitive development during early adolescence and adulthood contributes to self-consciousness and vulnerability. Adolescents are called to develop their own identity separate from their parents and understanding how others are actually evaluating them (Sebastian, 2008)

Brene Brown states that most …

Interpersonal Trauma And Mental Health Among Lgbq+ College Students: Examining Social Support And Trauma-Related Drinking As Mediators, Eryn Delaney

Theses and Dissertations

Despite the increased risk of childhood, adulthood, and lifetime interpersonal trauma among LGBQ+ individuals, existing research that has examined the influence of interpersonal trauma on mental health has primarily focused on LGBQ+ adolescents and samples of LGBQ+ community-based adults, and less on LGBQ+ emerging adults in college. Additionally, limited work has focused on mechanisms that might explain the relations between these variables. Thus, the current study tested the relations between interpersonal trauma (i.e., childhood sexual abuse, adulthood sexual victimization, and lifetime physical assault and IPV) and mental health outcomes (i.e., anxiety symptoms, depressive symptoms, and PTSD symptoms), and examined social …

Art Museum Docent Coordinators’ Perceptions: A Difficult Kind Of Balancing Act, Jennifer E. Schero

Theses and Dissertations

With visitors numbering in the millions, museums provide numerous entry points for attendees to engage with the objects in their care, including offering tours of their collections. Looking specifically at art museums, many institutions utilize volunteers to facilitate these guided looking experiences. Considerable research within the field of museum education focuses on the qualities of effective touring and methods and theories to support these endeavors. However, there is a lack of research focusing on the docent coordinators who oversee these volunteer guides. This study utilizes interpretive phenomenological analysis to explore perceptions of encyclopedic art museum docent coordinators concerning their preparation …

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 …

THE TRIFECTA OF TRANSFORMATIONAL CHANGE IN HEALTHCARE DESIGN

Pissing In The Pleasure Garden, Ellen Hanson

Theses and Dissertations

In this paper I will discuss self-representation and how my paintings refer to self-sexualization on the internet and depictions of muses in art history, allowing me to occupy the joint role of artist and muse through the repetition of my own image. My thesis exhibition, Pissing in the Pleasure Garden, uses freestanding canvases to imitate the form of a Hortus Conclusus. I use the closed garden to contend with the contradictions of control, eroticism, and voyeurism. Similar to the landscape of the early internet created by blogs and camgirl sites, the closed garden is both public and private.

≥I++ Wayward Self, Space, And Language, Mystie Do, Thu Tm Do

Theses and Dissertations

Having crossed different geographical and cultural borders, I can’t seem to position myself beyond society’s forced binaries of race, sexuality, and materiality. My personal diasporic experience drives me to bring together various presences, putting them next to one another, engaging them in dialogues. My works often share multiple space–time possibilities: a digital space, a physical site, a virtual alternity. Occupying these parallel worlds are varied ratios of mixtures of natural ecosystems, my own system of abstraction, and existing technological systems that allow us a level of individual engagement not previously available. I want to invite people to fluctuate between these …

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 …

Haven: Support For Mothers, Sarah Kincaid

Theses and Dissertations

This thesis explores how a nonmedical interior environment can provide support and care for mothers during the perinatal period in order to prevent maternal mental health (MMH) issues such as anxiety and postpartum depression.

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 …

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 …

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. …

From Knowledge About Trauma To Classroom Application: A Mixed Methods Examination Of Pre-Service Teacher Perspectives Of Trauma-Informed Practice, Jennifer Furman

Theses and Dissertations

The high prevalence, cognitive impact, and behavioral consequences of trauma have been heavily studied during the past few decades. The ways that teachers can ameliorate the effects of trauma have also been established, although mostly in K-12 contexts. The purpose of this explanatory sequential mixed methods study was to examine pre-service teachers’ knowledge, beliefs, and attitudes toward trauma-informed practices and to determine what salient experiences, courses, and understanding about trauma influenced the development of their knowledge, beliefs, and attitudes. Findings from the quantitative data demonstrated that pre-service teachers (n = 67) generally have a positive attitude toward trauma-informed practices. …

Perceived Organizational Support For Women’S Advancement And Turnover Intentions And Career Advancement Aspirations. The Mediating Role Of Job And Employer Satisfaction., Marta Squadrito

Theses and Dissertations

The purpose of this research is to examine whether the lack of organizational support for women’s advancement decreases female supervisors and managers’ aspiration to advance their careers and increases their turnover intentions and, the mediating effect of job satisfaction and employer satisfaction on the relationship between support and advancement aspirations and turnover intentions.

The antecedents of turnover intentions have been widely studied in the literature, while the antecedents of career aspirations, especially women’s, have not been a focus of much scholarly attention. Based on a review of the literature and drawing upon social exchange theory, and social cognitive theory, it …

The Impacts Of Peer Observation Roles And Teaching Characteristics On Teacher Self-Efficacy: A Secondary Data Analysis Study Using The Talis Survey, Elisa Tedona

Theses and Dissertations

It is important for teachers to have a high sense of self-efficacy, as it is one of the prime motivational forces influencing student learning, teacher quality, and in turn, overall success (Curry, 2015; Hattie, 2009; Klassen & Chiu, 2010). Teachers with high self-efficacy work harder, are more involved in learning, and have higher assurance (Bandura, 1994). For these reasons, it is imperative to study the influencers of teacher self-efficacy. Peer observations and observational feedback, a highly used practice in all schools, is one of those influencers. This cycle of observations and feedback provided to teachers is influential to teacher self-efficacy …

Evaluating The Effects Of Electronic Nicotine Delivery Systems On Smoking Reduction, Negative Mood, And Stress Among Smokers With Mental Illness, Cosima Hoetger

Theses and Dissertations

Introduction: Smokers with mental illness (MI) are disproportionately affected by negative health outcomes. Electronic nicotine delivery systems (ENDS) may represent a harm reduction tool for those who reduce and/or replace their cigarettes with ENDS. Little previous research has examined how smokers with MI respond to ENDS. This analysis aimed to address this research gap using secondary data from a randomized controlled trial of ENDS varying in nicotine delivery among smokers with and without current MI. The aims were to test 1) the effects of MI status, condition, and time on changes in smoking behavior and negative mood and stress measures, …
