Methods: Cone beam computed tomography (CBCT) scans of 106 previously treated maxillary molars seen for either recall or retreatment in the past 3 years were included in the study. Scans were reviewed by one endodontic resident and one board-certified endodontist to determine the POE (separate versus common) of the missed MB2 canal and the presence or absence of a periapical hypo-dense area. Association between AP and portal of exit was assessed using …

Dune Building Dynamics Impact Cross-Island Connectivity And Barrier Island Characteristics, Alexander Sabo

Theses and Dissertations

Located at the land-sea interface, barrier islands are important protective features that reduce wave energy and erosion from mainland areas. Further, barrier islands provide habitat for many different organisms and serve as popular areas for recreation and tourism. As sandy landforms, barrier islands are easily disturbed, but often recover after disturbance as a result of island plant communities, specifically dune building grasses. Disturbance on barrier islands is driven by storms, tides, and overwash events. After disturbance has occurred, dune grasses colonize the dunes allowing for dune building and habitat restoration. On the Virginia barrier islands, there are three dominant dune …

Children With Special Healthcare Needs: The Cost Of Medical Care, Kasey Dye

Theses and Dissertations

The purpose of this study was to explore factors that impact children with special healthcare needs’ (CSHCN) health insurance coverage and out-of-pocket medical expenses. The Ecological Model for Health Promotion developed by McLeroy et al. (1988) was the guiding theoretical framework for this study. Using data from the 2020 National Survey of Children’s Health, I conducted descriptive statistics, logistic regressions, and multilevel modeling analyses to determine if health insurance coverage and out-of-pocket expenses for CSHCN differed by individual, family, and community, organization, and policy factors. Results indicated that race, gender, disorder category, insurance type, and family’s federal poverty level were …

Home Disruption And Substance Use: The Moderated-Mediating Role Of Family Conflict And Stress Among Racial-Ethnic Minoritized College Students, Geovani Muñoz

Theses and Dissertations

The COVID-19 pandemic has disproportionately impacted first-generation college students who identify as racial-ethnic minorities (REM). Aside from the academic and health repercussions caused by COVID-19, little is known if home disruptions have increased substance use for REM college students. Specifically, increased home disruptions may directly relate to substance use and indirect relationships through increased family conflict and stress. Therefore, this master's thesis examined the direct relationships between home disruption and substance use. I also examined the relationships between home disruption and family conflict, as well as home disruption and stress. Further, I also investigated the relationships between family conflict and …

The Type Iv Pilus Secretin Bfpb: Structural Analysis And Binding Interactions, Janay I. Little

Theses and Dissertations

Enteropathogenic Escherichia coli (EPEC) causes severe diarrhea in young children. The type IV pilus (T4P) of EPEC, known as the bundle-forming pilus (BFP), plays an important role in EPEC pathogenesis. T4Ps are a family of surface appendages that are important for adhesion, colonization, biofilm formation, virulence, twitching motility and many other functions. One essential component of the BFP system is the secretin, BfpB. Secretins are a large family of integral outer membrane proteins found in T4Ps as well as type II and type III secretion systems, and filamentous phages. Details of the secretin structure have been limited to the overall …

An Introduction To Theatrical Scent Design As Compared To Traditional Design Areas With A Consideration For The Scientifically Notated Physical And Emotional Effects On The Human Body As It Potentially Relates To Future Creative Endeavors: A Framework, Katherine R. Holland

Theses and Dissertations

Traditional areas of theatrical design are established to the point of having a solid foundation for current and future designers to rely on as they strive to innovate. The same cannot be said for scent. I believe that art, like science, is a sector where the imagination is used to push the boundaries of what we currently know and can do. Artists are therefore entrusted with the responsibility to continue testing those boundaries, and that is what my topic lays the foundation for when it comes to scent. With my topic, I plan to look at the practical and ethical …

Patterns, Mechanisms, And Characterization Of Carbon Cycling Stability Following Partial Forest Disturbance, Kayla C. Mathes

Theses and Dissertations

Among the most essential questions in the era of climate change is how the forest carbon (C) cycle will respond to an increase in the extent of biotic disturbances from insects and pathogens. While research has focused on stand-replacing disturbance regimes, less is known about C cycling stability following partial disturbances that produce gradients of disturbance severity. Belowground C cycling responses to disturbance are especially poorly understood, even though temperate forest soils contain up to 50% of total ecosystem C and soil respiration (R_s) accounts for more than half of temperate forest C loss. Interpreting trends and mechanisms …

Exploring The Effect Of Early Motor Delay And Physical Therapy Interventions On The Parent-Child Relationship, Rebecca Molinini

Theses and Dissertations

Emotional availability (EA) or the ability of the parent-child dyad to engage emotionally and partake in congruent and mutually enjoyable interactions, is essential for familial health and well-being. EA is considered the “connective tissue” of healthy parent-child relationships and is associated with secure attachment, maternal mental health, and children’s adaptive development. Most evidence supporting the integral role of EA on healthy outcomes is supported by typically developing populations in which adults present with a social or biological risk factor such as experiencing past traumas of adversities with mental health. In line with the transactional model of development, children are equal …

Development Of Tangible Code Blocks For The Blind And Visually Impaired, Hyun Woo Kim

Theses and Dissertations

The fields of Science, Technology, Engineering, and Mathematics (STEM) have been growing at an accelerating rate in recent times. Knowing how to program has become one key skill for entering all of these STEM fields. However, many students find programming difficult. The block based programming language, Scratch, was specifically designed to lower hurdles to learning how to program for sighted students. Unfortunately, although very effective and widely used in K12 classrooms, Scratch, similar to other block based languages, is inaccessible to students who are blind and visually impaired (BVI). This thesis is part of a larger project to make the …

Practice Elements Delivered By Teachers To Support Children Who Display Challenging Behaviors In Business-As-Usual Early Childhood Settings, Navneet Kaur

Theses and Dissertations

Approximately 15-25% of children ages 3 to 5 years in early childhood settings display chronic challenging behaviors that increase their risk for developing an emotional and behavioral disorder. The early onset of emotional and behavioral disorders has long-term negative implications for these children. Therefore, it is vital to address these problems early on. One approach is through teacher-delivered practices (i.e., specific strategies, such as praise) and programs (i.e., manualized interventions that contain a collection of practices) in the classroom. Some practices and programs have shown positive outcomes for children. However, when practices and programs do not outperform business-as-usual group (BAU), …

Incorporating Noh Training Into Contemporary Western Theatre: An Examination Of The Benefits To Implementing Noh Theatre And Suzuki Training Into Western Performance Pedagogy, Baylee A. Holloran

Theses and Dissertations

Noh theatre is a traditional Japanese theatre practice that focuses on isolated and intentional physicality and separating actor personality from character. It is an imaginative and heightened performance that differs greatly from Western theatrical realism. This thesis examines Noh theatre, its origins, and why it should be more implemented into Western acting pedagogy. I start by describing what Noh is as an art form, from the ritualistic aspects to how it is staged and performed. Then I outline the religious and historical significance of Noh and how they are showcased in its storytelling and performance. I analyze the pedagogies of …

Model Based Systems Engineering Approaches To Chemicals And Materials Manufacturing, Quang Le

Theses and Dissertations

Model-based systems engineering (MBSE) is part of a long-term trend toward model-centric approaches adopted by many engineering disciplines. This work establishes the need for an MBSE approach by reviewing the importance, complexity, and vulnerability of the U.S. chemical supply chains. The origins, work processes, modeling approaches, and supporting tools of the systems engineering discipline (SE) are discussed, along with the limitations of the current Process Systems Engineering (PSE) framework. The case is made for MBSE as a more generalizable and robust approach. Systems modeling strategies for MBSE are introduced, as well as a novel MBSE method that supports the automation …

Investigating Actor Speech Training History Through The Lens Of Knight-Thompson Speechwork: How A Nonprescriptive Approach Revolutionizes The Field And Applications Outside Of A Theatrical Context, Harrison G. Runion

Theses and Dissertations

Speech training for actors in the United States has a history deeply rooted in prescriptive practices. Many speech trainers have and still do teach from a model that they consider to be the “correct” way to speak. These practices have proven to be quite damaging to students’ emotional and cultural identities, as speech is an inherent part of who we are as individuals. This thesis first examines such speech training pedagogies of the past, specifically the progression of William Tilly’s World English to Edith Skinner’s Good American Speech. Doing so establishes the necessary contextual understanding required to provide an alternative …

Isoprenylation Inhibition Significantly Reduces Ige Mediated Mast Cell Function And Allergic Disease, Jordan Dailey

Theses and Dissertations

Allergic disease is the 6^th leading cause of chronic illness in the US and accounts for billions of dollars in healthcare annually. Mast cells are tissue resident innate immune cells linked to allergic disease and activated by IgE and other ligands. Upon activation, they release histamine, cytokines, chemokines, proteases, and lipid mediators evoking allergic symptoms. New ways of targeting mast cells could greatly benefit allergic disease therapy. Previous findings supported repurposing statin drugs, such as Fluvastatin, as a therapeutic treatment of allergic disease reduced allergic symptoms in vitro and in vivo. We found that Fluvastatin suppressed IgE-mediated mast cell …

Youth And Caregivers' Perceptions Of Racial Socialization: Examining The Interactive Role Of Risk And Cultural Resilience Factors As Predictors And Mental Health As Outcomes, Arlenis Santana

Theses and Dissertations

Black families' mental health, including that of the children and caretakers, is a persistent public health concern. Existing work documents that parental racial socialization messages are a protective process for the psychological well-being of Black children, youth, and emerging adults (Bannon et al., 2009). The majority of work to date has focused on youth, and we have limited information about the effects of racial socialization on caregivers’ mental health outcomes. It is also essential to examine the relation between racial socialization and outcomes among caregivers because, aside from their identity as parents, caregivers have other identities and experiences that deserve …

Theses and Dissertations

Abstract

This is an invitation into the delicate space of living between two worlds, of having feelings of happiness and sadness at the same time. Delicate emotions and situations which are not easy to share but are paramount in my research of what it takes to want more out of being just a parent, come from a certain country than the one I am living in, and navigate between two cultures. This is a journey around some of the experiences I have faced when I found myself in a different space other than the one I grew up in. The …

A Standardized Pipeline For Isolation And Assembly Of Genomes From Symbiotic Bacteria In Whole Louse Genomic Sequence Data., Mohammad Mikail I. Bala

Theses and Dissertations

Many insects are known to harbour intracellular and heritable bacteria (endosymbionts), which provide their hosts with adaptive traits. Whole insect gDNA shotgun sequencing projects often sequence the genome of endosymbiont, in addition to the insect’s genome. There are approximately 600 whole genome shotgun libraries from insects available on the public repository (NCBI), which can be mined to obtain endosymbiont genomes. The assembly and annotation of endosymbiont genomes can contribute towards the exploration of their role as obligate symbiotic partners. However, de novo assembly of an endosymbiont genome, continues to be challenging, when the host and/or enteric bacterial gDNA is present …

Utilization Of Occupational Therapy Services For Patients With Cancer In Acute Care Settings, Christine Mcnichols

Theses and Dissertations

For patients with cancer diagnoses, effects from the disease or as a result of cancer treatments can cause profound impairments impeding patient functioning and independence. These assaults to the independent achievement of activities have far reaching implications and linkages to a patient’s length of stay and their likelihood of a hospital readmission. Unfortunately, occupational therapy services have frequently been found not to be ordered for patients with cancer, even when there have been demonstrated functional deficits and needs. Through the analysis of patient records from a National Cancer Institute hospital over 5 years, the current study investigated occupational therapy services …

The Impact Of A Parent-Only Pediatric Obesity Intervention Program On Quality Of Life In Racially Diverse Children, Taylor Vashro

Theses and Dissertations

Pediatric obesity has been associated with significant decrements in pediatric quality of life (QOL) comparable with severe pediatric diseases such as cancer. Parenting interventions have yielded health benefits for children with obesity; however, few studies have investigated the impact of parent-focused interventions on QOL in children with overweight and obesity. This study investigated the impact of a 6-week intensive parenting intervention program on the QOL of 5-12 year old, predominantly Black children with overweight and obesity. Parents were randomized into either the parenting intervention (NOURISH+) or a control group, and QOL, as well as variables related to child and parenting …

Codon-Optimized Tdp-43 Mediates Neurodegeneration In A Drosophila Model Of Als/Ftld, George R Jackson, Shreyasi Chatterjee

Faculty, Staff and Students Publications

Transactive response DNA binding protein-43 (TDP-43) is known to mediate neurodegeneration associated with amyotrophic lateral sclerosis (ALS) and frontotemporal lobar degeneration (FTLD). The exact mechanism by which TDP-43 exerts toxicity in the brains, spinal cord, and lower motor neurons of affected patients remains unclear. In a novel Drosophila melanogaster model, we report gain-of-function phenotypes due to misexpression of insect codon-optimized version of human wild-type TDP-43 (CO-TDP-43) using both the binary GAL4/UAS system and direct promoter fusion constructs. The CO-TDP-43 model showed robust tissue specific phenotypes in the adult eye, wing, and bristles in the notum. Compared to non-codon optimized …

Mortality Difference From Klebsiella Aerogenes Vs Enterobacter Cloacae Bloodstream Infections, Lynn Zechiedrich, Barbara W Trautner

Faculty, Staff and Students Publications

Members of the order Enterobacterales, including Escherichia coli , Klebsiella species and Enterobacter species, are important pathogens in healthcare-associated infections. Higher mortality has been reported from infections due to Klebsiella pneumoniae than from E. coli , but prior studies comparing Enterobacter aerogenes (recently renamed Klebsiella aerogenes ) bacteraemia and Enterobacter cloacae complex bacteraemia have yielded conflicting results regarding whether clinical outcomes differ. We found bacteraemia with K. aerogenes was independently associated with greater risk of 30-day mortality than bacteraemia with Enterobacter cloacae complex.
