Examining Adolescent Voices In Urban Montessorianism Within The Third Plane Of Development., Raymond Edward Green
Examining Adolescent Voices In Urban Montessorianism Within The Third Plane Of Development., Raymond Edward Green
Electronic Theses and Dissertations
Although there is a significant body of research surrounding Montessori education, little research has sought to capture the voices of adolescents, specifically high school students in urban settings (Dr. Montessori’s third plane of development) learning through the Montessori Method. Problem: Legislators, policy writers, district and school-level leaders mandate and implement reforms with minimal to no adolescent input. Further, adolescents are not part of the reform implementation process or identifying desired outcomes of said reform initiatives. Purpose: The purpose of this study was to examine adolescent’s perspective of their urban high school Montessori education, and their role in helping to develop …
Kurt Vonnegut, Modernity, And The Self: A Guide To The Good Life., Josh Simpson
Kurt Vonnegut, Modernity, And The Self: A Guide To The Good Life., Josh Simpson
Electronic Theses and Dissertations
What are people for? This is a question Kurt Vonnegut raises in his first novel, 1952’s Player Piano. Over five decades later, when he concludes a career with 2005’s A Man Without a Country, he is still asking, “What is life all about?” (66). These are the central questions for Vonnegut, and his novels, short stories, essays, interviews, correspondence, and commencement addresses offer a singular, life-long attempt at an answer. In this dissertation I offer a reading of Vonnegut not just as a writer concerned with philosophical questions, but rather, on a deeper, more personal level, as a …
Data Linkage For Crash-Injury Outcome Assessment., Aryan Hosseinzadeh
Data Linkage For Crash-Injury Outcome Assessment., Aryan Hosseinzadeh
Electronic Theses and Dissertations
Introduction: Traffic crash reports lack detailed information about emergency medical service (EMS) responses, the injuries, and the associated treatments, limiting the ability of safety analysts to account for that information. Integrating data from other sources can enable a better understanding of the characteristics of serious crashes and further explain variance in injury outcomes. In this thesis, first, a heuristic approach is proposed and implemented to link crash data to EMS run data, patient care reports, and trauma registry data. Next, the method was adapted through larger datasets in a statewide linkage effort. The performance of the heuristic method was compared …

Adipose-Derived Stromal Vascular Fraction Therapy Improves Age-Related Adrenergic Mediated Microvascular Dysfunction And Increases Revascularization Potential Following Injury., Gabrielle Brown
Electronic Theses and Dissertations
The role of the microcirculation is to balance blood flow and oxygen delivery to meet local metabolic and oxygen demands. With advancing age, the health of the endothelium declines leading to improper augmentation of the microcirculation; decreasing vasoreactivity and angiogenic potential which can further increase the risk of ischemia. The multiple contributing factors that drive the decline in endothelial health with age make traditional pharmacological interventions challenging whereas cell-based therapies can exert multifactorial gains. Adipose-derived stromal vascular fraction (SVF) is an emerging therapeutic for its easily accessible, autologous, anti-inflammatory, and angiogenic properties. It is a heterogenous population comprised of leukocyte …

Spectroscopic Measurements Of Meibum Compositional, Structural, And Functional Relationships To Elucidate The Role Of Meibum In Dry Eye., Anthony Chigozie Ewurum
Electronic Theses and Dissertations
The major aim of my dissertation was to investigate the etiology of dry eye disease which affects about 7 million people in the United States, causing symptoms that can lead to visual disturbance. Correlation between dry eye and an abnormal lipid layer of the tear film has been found. Tear film lipids originate mostly from the meibomian glands. Cholesteryl ester (CE) and Wax ester (WE) lipids make up most of the human meibum lipidome and the CE/WE ratio has been shown to decrease in patients with meibomian gland dysfunction. Model studies using synthetic CE and WE, although providing some insight, …
Machine Learning Approaches For Early Prediction Of Hypertension., Heba Elsayed Mohamed Kandil
Machine Learning Approaches For Early Prediction Of Hypertension., Heba Elsayed Mohamed Kandil
Electronic Theses and Dissertations
Hypertension afflicts one in every three adults and is a leading cause of mortality in 516, 955 patients in USA. The chronic elevation of cerebral perfusion pressure (CPP) changes the cerebrovasculature of the brain and disrupts its vasoregulation mechanisms. Reported correlations between changes in smaller cerebrovascular vessels and hypertension may be used to diagnose hypertension in its early stages, 10-15 years before the appearance of symptoms such as cognitive impairment and memory loss. Specifically, recent studies hypothesized that changes in the cerebrovasculature and CPP precede the systemic elevation of blood pressure. Currently, sphygmomanometers are used to measure repeated brachial artery …

Artificial Intelligence (AI)-driven recommender systems have been gaining increasing ubiquity and influence in our daily lives, especially during time spent online on the World Wide Web or smart devices. The influence of recommender systems on who and what we can find and discover, our choices, and our behavior, has thus never been more concrete. AI can now predict and anticipate, with varying degrees of accuracy, the news article we will read, the music we will listen to, the movies we will watch, the transactions we will make, the restaurants we will eat in, the online courses we will be interested …
Etracellular Vesicles From Lactobacillus Rhamnosus Gg Protect Against Alcohol-Induced Liver Injury Through Suppression Of Intestinal Mir 194 And Subsequent Activation Of Fxr In Mice., Mengwei Jiang
Electronic Theses and Dissertations
Numerous studies have reported the efficacy of probiotics for alcohol-associated liver disease (ALD). These studies indicate a strong interest among the scientific and medical communities in identifying alternative or adjunctive approaches for ALD, for which there is no effective or widely accepted therapeutic option. However, in-depth molecular knowledge on how probiotics render their effects is lacking. Patients with ALD often have increased hepatic bile acids (BAs), which can be toxic and are an important causative factor in liver injury and hepatocyte death. BAs are released into the intestines and serve not only as a “detergent” to promote fat absorption, but …
Statistical Methods For Assessing Drug Interactions And Identifying Effect Modifiers Using Observational Data., Qian Xu
Electronic Theses and Dissertations
This dissertation consists of three projects related to causal inference based on observational data. In the first project, we propose a double robust to identify the effect modifiers and estimate optimal treatment. Observational studies differ from experimental studies in that assignment of subjects to treatments is not randomized but rather occurs due to natural mechanisms, which are usually hidden from the researchers. Many statistical methods to identify the treatment effect and select the optimal personalized treatment for experimental studies may not be suitable for observational studies any more. In this project, we propose a exible outcome model to select the …
Hiv And The African American Church: Millennial Faith Leader's Perspectives., Kelsey Leann Burton
Hiv And The African American Church: Millennial Faith Leader's Perspectives., Kelsey Leann Burton
Electronic Theses and Dissertations
African Americans are disproportionately impacted by HIV compared to other racial groups. Stigma surrounding HIV has created challenges for effective HIV prevention and stigma reduction programs. The African American church has been criticized for its slow and stigmatizing response to the HIV epidemic. Despite this, African American faith leaders play significant roles in guiding the perspective of the community. Numerous studies examine African American pastors’, faith leaders’, and ministers’ perspective about HIV and other HIV-related topics. However, there is no research that specifically examines young African American pastors’ perspectives of addressing HIV, stigma, and prevention. The purpose of this dissertation …

Perovskites are functional materials with the general formula ABO3 (A = alkali, alkaline earth or lanthanoid cations and B = transition metal or main group cations). These materials are marked by a variety of crystal structures and interesting properties such as colossal magnetoresistance, ferroelectricity, multiferroicity, superconductivity, pseudocapacitance, gas sensing, charge transport, and electrocatalytic properties. The formula of perovskite can be written as AA’BB’O6, when there is ordering between two cations over A and B-sites. Such compounds are called double perovskite oxides. Some amount of oxygen could be lost from crystal structure without decomposition of the phase. Such …
Lysosomal Evasion Of Legionella Pneumophilia The Effector., Bethany Vaughn
Lysosomal Evasion Of Legionella Pneumophilia The Effector., Bethany Vaughn
Electronic Theses and Dissertations
Legionella pneumophila is a Gram-negative facultative intracellular bacterium found in freshwater environments that has co-evolved to survive and proliferate in various amoeba and protozoan species, which serve as the natural host for the bacterium. Humans are an accidental host of L. pneumophila, where infection occurs upon inhalation of aerosolized water droplets that contain the bacteria. Intracellular proliferation of L. pneumophila in alveolar macrophages is essential for manifestation of pneumonia, designated as Legionnaires’ Disease. Biogenesis of the legionella containing vacuole (LCV) occurs via interception of ER-Golgi vesicle trafficking and avoids the default endosomal/lysosomal degradation pathway. Intracellular proliferation of L. pneumophila …
Findings And Understandings Of 'Home': An Ethnographic Study Of How Homeless People And Displaced Persons Negotiate The Word 'Home'., Abby F Perez
Electronic Theses and Dissertations
This dissertation is an ethnographic study of various meanings of the word ‘home’ and how the word ‘home’ is used by homeless, evicted, and displaced persons, and by the researcher of the study, to negotiate boundaries and relations of power to achieve goals, both moral and material.Scholarly research on home in urban studies and sociology has produced many definitions and meanings of the word ‘home’ and concepts of home, but often neglects to consider the way the word itself is experienced, personally, by individuals and how to make sense of the way these personal experiences relate to official meanings of …
Western Christianity And The Origins Of Antiblackness, Eurocentrism, And White Supremacist Ideology., John Chenault
Western Christianity And The Origins Of Antiblackness, Eurocentrism, And White Supremacist Ideology., John Chenault
Electronic Theses and Dissertations
This qualitative study investigates the cult(ural) and intellectual history of Western Christianity to address a significant gap in the literature pertaining to the origins of whiteness/antiblackness in the West and its subsequent socialization worldwide. Western Christianity’s seminal role in the social construction of the whiteness/antiblackness dichotomy has been undertheorized, neglected, and ignored. This study finds early Christian theologians categorically imposed conceptual metaphors about Blackness on African people that depicted them as the exemplars of evil to teach Christian doctrine about sin and salvation. It connects these original antiblack discourses directly to the theo-political arguments Western European Christians used centuries later …

Person-Centered Decision-Making And Socio-Cultural Contexts Influencing Cesarean Deliveries: A National Analysis., Alice M. Story
Electronic Theses and Dissertations
The cesarean delivery rate has increased and accounts for a third of pregnancies in the U.S., especially among marginalized women. This study applied a newly developed conceptual model to identify potential areas of influence that could reduce rates of cesarean deliveries. The Giving Voice to Mothers - United States data was used for analyses to predict covariates associated with having a cesarean delivery vs. spontaneous vaginal delivery (n=1,876). Significant covariates were determined and included the following: having a prior cesarean delivery (OR: 14.11, 95% CI: 7.99 - 24.90); more than one child (OR: 0.21, 95% CI: 0.13 - 0.35); elevated …
Determinants Of Caregiver Burden Among Informal Caregivers Looking After Older Adults With Alzheimer's Disease In Saudi Arabia., Sultan Ali Shubair
Determinants Of Caregiver Burden Among Informal Caregivers Looking After Older Adults With Alzheimer's Disease In Saudi Arabia., Sultan Ali Shubair
Electronic Theses and Dissertations
Caregiver burden in Alzheimer’s Disease (AD) is a significant factor in the deterioration of caregivers’ physical and mental health. Moreover, increased caregiver burden has been associated with the decline in quality of life and the reduced quality of care for the care recipient. However, the level of caregiver burden perceived by informal caregivers of care recipients with AD can be varied with the impact of different factors related to the caregiver, care recipient, and caregiving process. Identifying factors associated with caregiver burden and exploring factors that account for variation in caregiver burden are vital to prevent adverse outcomes of caregiver …

“I Think It's Male Privilege”: A Qualitative Study Of Personal, Behavioral, And Socio-Environmental Factors Influencing High Risk Sexual Behavior And Hiv Transmission Among Heterosexual Adult Males In Ghana., Nana Ama Aya Erzuah Bullock
Electronic Theses and Dissertations
There are roughly 340,000 adults and children living with HIV. Despite the progress in the global response and the lowing of infections, HIV rates in Ghana remain stable. Cultural and societal norms that exist at a given time and place influence masculine socialization and behavior. These norms promote heterosexual men’s engagement in high-risk sexual behaviors which result in HIV infections. Factors such as HIV knowledge, risk perception, male condom use, HIV testing, and counseling which minimize the risk of HIV, are also influenced by these norms. Men have been identified as assets and advocates for behavior change and social responsibility …
Mission Drift And The Effectiveness Of Resource Dependence Theory In An Internally Resource-Constrained Environment., Kirsten Bullock
Mission Drift And The Effectiveness Of Resource Dependence Theory In An Internally Resource-Constrained Environment., Kirsten Bullock
Electronic Theses and Dissertations
Why are some organizations able to maintain focus on their mission while others founder? This theoretical and empirical dissertation examines the relationships among funding sources, management practices, and organizational stigma within an internally resource-constrained environment. Using Resource Dependence Theory (RDT) as a basis to manage external resource dependencies, I build a theoretical model and empirically test a research model to understand how funding source affects mission drift, how management practices might help organizations manage that drift, and what effect organizational stigma might have on those relationships within an environment of internal resource constraints. Specifically, this study hypothesizes that nonprofits that …
The Roles Of Pon2 In Mitochondrial Physiology, Lung Tumor Cell Proliferation, And Lung Tumorigenesis., Aaron Whitt
The Roles Of Pon2 In Mitochondrial Physiology, Lung Tumor Cell Proliferation, And Lung Tumorigenesis., Aaron Whitt
Electronic Theses and Dissertations
Paraoxonase 2 (PON2) is an intracellular, multifunctional enzyme with near-ubiquitous tissue distribution. Within cells, PON2 is localized to mitochondria and endoplasmic reticulum (ER), where it mitigates the formation of reactive oxygen species (ROS). PON2’s chief enzymatic function is its lactonase activity, through which it catalyzes the hydrolysis of a bacterial quorum-sensing molecule, N-(3-oxododecanoyl)-l-homoserine lactone (C12), effectively disrupting bacterial intercellular communication and protecting against infection. C12 is produced by the opportunistic pathogen Pseudomonas aeruginosa and has been shown to disrupt various aspects of eukaryotic host cell physiology and evoke apoptotic cell death through the activity of PON2. Additionally, PON2 has garnered …

The Role Of Obesity In Macrophage-Mediated Mechanisms Promoting Early-Onset Colon Cancer., Katharina Marietta Scheurlen
Electronic Theses and Dissertations
Early-onset colon cancer (EOCC) is a leading cause of cancer death among people younger than 50 years of age in the United States and is associated with metabolic dysfunction and obesity. Anti-inflammatory tumor-associated macrophages (TAM) and low Peroxisome Proliferator Activated Receptor Gamma (PPARγ) gene expression in colon cancer (CC) tissue promote tumor progression and decreased patient survival. Obesity-related hormones, such as leptin and adiponectin, have the potential to affect gene expression in TAM to promote CC progression and thereby link obesity and EOCC. The aim of this project was to identify target genes in human CC and to investigate the …
