Dysconscious Racism And Racial Microaggressions In The Public School System, Ryan Lee

Doctoral Dissertations

Dysconscious racism and racial microaggressions are two forms of racism that exist in public schools today. Dysconscious racism is a form of racism that “tacitly accepts the dominant White norms and privileges” in a given environment while racial microaggressions are brief and commonplace indignations to the target person or group whether it was intentional or unintentional (Sue et al., 2009). Teachers of color face these subtllte forms of racism within their own workplaces. The researcher conducted a qualitative study by interviewing six public school K-6 teachers of color of different ethnicities who teach in various school districts across the South …

Engaging Feminism, Transforming Institutions: How Community Engagement Professionals Employ Critical Feminist Praxis To Re-Imagine And Re-Shape The Public Purpose Of Higher Education, Patricia Star Plaxton-Moore

Doctoral Dissertations

Most higher education institutions have mission statements articulating a commitment to serve the public good, and venerate the broader historical project of higher education as a force that improves the lives of individuals and communities. However, the public purpose of higher education is perpetually embattled by intersecting forces of neoliberalism, positivism, and settler colonialism that emphasize priorities like generating revenue, chasing prestige, developing real estate, and connecting students with high paying careers. As our society continues to grapple with pervasive social and environmental injustices, it is imperative that we clarify and strengthen higher education’s civic role in shaping a more …

Women Who Lead: A Feminist Phenomenology Of Crisis Leadership In Higher Education, Ingrid Helene Mcvanner

Doctoral Dissertations

The landscape of higher education is rife with crisis events, ranging from the global COVID-19 pandemic to natural disasters and institutional and industry-wide scandals; yet, most institutions of higher education are unprepared to tackle these crises as they arrive. As an industry, higher education is also largely dominated by men at its upper echelons, despite being a field that is predominantly staffed by women. Amidst the backdrop of the attention COVID-19 has brought to female world leaders and the quest for parity in higher education leadership positions, this study sought to explore the lived experiences of women leaders in higher …

The Significance Of Jesuit Educational Institution In The Reconstruction Of Postcolonial And Post-Conflict East Timor, Plinio Do Rosario Gusmao Dosreis Martins

Doctoral Dissertations

East Timor, as a postcolonial and post-conflict country, has striven to develop its educational system for almost two decades after its independence in 2002. The current educational system with the Portuguese language as the medium of instruction has been a challenge for teachers and students in the teaching and learning process. The fact that teachers and students are still using Tétum as a supplementary language to explain and express ideas shows that the educators and learners are still struggling with Portuguese despite the efforts of East Timor government to bridge the language gap.

Teachers and students, conversely, acknowledge that the …

The Influence Of Strength And Mobility On Lumbar Biomechanics During Lifting, Christopher S. Patterson

Loma Linda University Electronic Theses, Dissertations & Projects

Weakness of the lumbar and hip extensors muscles as well as limited hip flexion mobility have been proposed to contribute to greater lumbar spine loading and greater lumbar flexion during functional tasks. The purpose of the current study was to examine the associations among hip and lumbar spine extension strength, hip flexion mobility and lumbar spine biomechanics during a squat lifting task. Fifty healthy adults participated in the study. Strength of the lumbar extensors and hip extensors was measured using a motor driven dynamometer. Hip range of motion was assessed using a 3D motion capture system. Participants lifted boxes of …

Another Step In Diagnostics Consultation Model© Actualization: Examining The Impact Of Consultation Workflow Processes On Providers' Clinical Decision Making, Elizabeth K. Leibach

Theses and Dissertations

Background
Communication errors in health services delivery significantly compromise quality in clinical decision making (CDM). Diagnostic information generated by clinical laboratories (CL) accounts for as much as 93% of objective data in the clinical record and therefore is foundational in CDM. This work describes the Diagnostics Consultation Model© (DCM©), a CL communications portal, which supports CDM within interprofessional teams, providers, and institutions. Specific aims were to develop and validate a workflow prediction index (the complexity index, CI) to assign resolution of consultation requests based on an algorithm comprised of characteristics available at the point of consultation initiation. The CI functions …

Cardiac Arrest And Global Ischemia Reperfusion Injury: Role Of Mitochondria And Cannabinoid Receptor 2 Signaling., Jennifer L. Bradley

Theses and Dissertations

We explored the effects of cardiac arrest on mitochondria populations and heart whole tissue lysate proteomics utilizing the Weil Institute’s in vivo rat model of cardiac arrest and cardiopulmonary resuscitation. We have discovered that brain mitochondria are more sensitive to global ischemia compared to heart mitochondria. Additionally, complex I is the most sensitive electron transport chain complex to ischemic injury and is a major control point of the rate of oxidative phosphorylation following cardiac arrest and cardiopulmonary resuscitation. Preservation of brain mitochondrial activity and function during cardiac arrest may enhance outcomes and recovery.

A recent article focusing on acute myocardial …

Preventing Obesity: A Social Ecological Exploration Of Centers For Disease Control Prevention Strategies And Guidance Toward Healthy Eating, Physical Activity, And Communities, Ryan Kelly

Theses and Dissertations

Abstract

Obesity has reached nearly 40% of the adult public in the United States, costing the citizen taxpayer over $200 billion annually in healthcare costs. Those suffering from obesity deal with multiple physical and mental repercussions. Through a content analysis of four Centers for Disease Control (CDC) documents and guided by the conceptual framework of the social ecological model, this research explores the federal approach to preventing obesity. The analysis finds that CDC solutions to obesity involve connecting people to each other and healthier choices, an orientation toward local public administration, and an emphasis on environmental and infrastructure improvements. The …

Targeting Transferrin Binding Protein A For Vaccine Development In Neisseria Gonorrhoeae, Ashley Greenawalt

Theses and Dissertations

Neisseria gonorrhoeae, the causative agent of the sexually-transmitted infection gonorrhea, has recently been labeled a superbug. With dwindling treatment options, there is urgent need for a gonococcal vaccine. TonB-dependent transporters (TDTs) are important gonococcal virulence factors that allow the gonococcus to pirate metals directly from host proteins. The TDTs, TbpA and TbpB, are promising vaccine targets because both proteins are expressed and highly conserved in gonococcal strains, and they are not subject to high-frequency antigenic variation. Because the Tbps bind to host protein as their natural function, our immune system does not recognize them as foreign antigens; thus, immunogenicity is …

Symptom Self-Management In Adolescents Following A Concussion, Amanda Hodges

Theses and Dissertations

Background: Adolescents experience a variety of symptoms following a concussion that affect their everyday life. Initial management consists of physical and cognitive rest followed by a gradual return to activities while monitoring symptoms. Managing concussion symptoms in adolescents is a challenge due to their lifestyle and developmental needs but it is the key to improving adolescents’ lives. Symptom self-management is the prevention and control of symptoms and has been shown to improve health outcomes but has not been studied in adolescents with concussion symptoms. Using the Individual and Family Self-Management Theory (IFSMT), the purpose of this study was to …

Socio-Ecological Predictors Of Social Connection Among Older Adults, Georganna Amateau

Theses and Dissertations

Decades of research has established an unequivocal link between states of social connection and health status. Lack of social connection, whether construed as social isolation or loneliness, negatively influences health and is highly associated with cardiovascular disease, high blood pressure, fall risk, and premature death. Despite extensive research on social isolation and loneliness, evidence relative to the broader construct of social connection suffers. Few studies inform practice standards for community-based organizations. This study aimed to develop a multidimensional, continuous composite variable of social connection and use the composite variable to examine predictors with a socio-ecological lens.

A secondary data analysis …

“Insurance Doesn’T Care About The Patient”: An Institutional Ethnography Of The Influence Of Professional Autonomy On The Provision Care For Medicaid Dental Patients With Disabilities, Stephanie Lau

Theses and Dissertations

In terms of unmet needs for people with disabilities (PWD), dental care is number three behind residential care and employment (Fisher, 2012). Regardless of disability, oral healthcare traverses all disability diagnoses and can be a significant factor in quality of life (Deckler, 2011; Griffin et al., 2007; Norwood & Slayton, 2013). When attempting to secure oral healthcare, people with disabilities face many challenges, including lack of access, lack of provider education on proper care of PWD, and difficulty finding a willing dental provider (Deckler, 2011; Fisher, 2012; Kennedy, 2009).

The purpose of this study was to investigate professional practices and …

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 …

Systematic Structure-Activity Relationship Studies Of Nalfurafine, Mengchu Li

Theses and Dissertations

Today’s opioid crisis is one of the most challenging public health emergency. Two million Americans suffer opioid addiction. Over 20 million adults are affected by daily pain without non-addictive analgesics.

Kappa opioid receptor (KOR) is one of the most studied new pain targets void of abuse liability. KOR agonists have shown potent analgesia and also potential in alleviating opioid addiction. The only approved KOR agonist in clinic is nalfurafine (NFU). Though not leading to addiction, the analgesic effects of NFU are accompanied by sedative side effects. Therefore, we designed a systematical structure-activity relationship study of NFU for developing non-addictive analgesics. …

Detrimental Role Of Irf1 In Myeloid Cells During Influenza Infection, Bianca L. Baum

Theses and Dissertations

The influenza virus is constantly evolving new ways to overcome both innate and vaccine-induced host defenses, making the innate immune response a critical therapeutic target for minimizing morbidity and mortality caused by infection. Here we examined the role that interferon regulatory factor 1 (IRF1) plays in regulating host innate immune responses in myeloid cells. We found that knocking out IRF1 from myeloid cells in mice (IRF1^DMy) led to a partial protection during IAV infection. Interestingly, recruitment of bone marrow derived myeloid cells as well as NLRP3 inflammasome expression were decreased in the lungs of IRF1^DMy mice, whereas …

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 …

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 …

Virtual Reality Tool For Visualizing The Oral Microbiome, Alexus M. Harris

Theses and Dissertations

There are limited teaching tools for helping both students and patients understand the oral microbiome. It is important to understand the oral microbiome as it heavily influences the health of your oral cavity and the dysbiosis of disease. The oral microbiome influences other aspects of health and serves as an indicator for health. With a greater understanding of the oral microbiome, patients can make healthier lifestyle changes and dentists can better educate their patients. For that reason, the goal of this project was to create a virtual reality tool for visualizing the oral microbiome. The assets for the VR tool …

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 …

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 …
