Development And Validation Of A Volunteer Adult Literacy Tutor Perception Feedback Scale, Robert Craig

Theses and Dissertations

This exploratory study developed and validated a Volunteer Adult Literacy Tutor Perception Feedback Scale (VALTPFS). The VALTPFS is a self-report questionnaire that measures the perceptions of one-on-one adult literacy tutors about their values, knowledge sharing, and satisfaction. This instrument is designed to assess the perceptions of adults who volunteer to provide literacy instruction to tutees who are U.S. born native English language speaking adults. The theoretical framework used to inform the development of the VALTPFS is the community of practice (CoP). The CoP framework was used to identify subscales from instruments with established psychometric credentials to operationalize the VALTPFS. As …

Race, Weight, Gender And The Embodied (Odied, Odied) Consciousness Of Big-Bodied Black Women Educators: A Phenomenological Study, Kendra D. Johnson

Theses and Dissertations

Big-Bodied Black women in the United States have perpetually navigated the veritable dichotomy of being hyper-visible and invisible (Beauboeuf-Lafontant, 2003; Fleetwood, 2001; Strings, 2019). Fat Black female bodies have borne the burden of exaggerated tropes and exploitation throughout history, stripping them of their femininity and humanity and resulting in a unique form of objectification (Strings, 2019). Inconsistent messages about BBWs, their bodies, and their value in society have endured for generations. They have been essential in constructing the controlling images of Black womanhood in the U.S. (Collins, 2000). The controlling images all evoked thoughts about the suitability of Black women …

Effect Of Clear Aligner Attachment Design On Extrusion Of Maxillary Lateral Incisors: A Randomized Clinical Trial, Justin Groody

Theses and Dissertations

Introduction: The aims of this randomized clinical trial were to compare the efficacy of extrusion of maxillary lateral incisors among “optimized”, rectangular “horizontal”, rectangular horizontal “incisally beveled”, rectangular horizontal “gingivally beveled” attachments, and to provide a clinically relevant recommendation for attachment planning for extrusion of maxillary lateral incisors during aligner treatment.

Methods: 30 16-to-58 year old Invisalign patients and 56 maxillary lateral incisors requiring extrusion were randomly allocated to one of four attachment groups (optimized, horizontal, incisally beveled, and gingivally beveled). Participants were recruited from two private practice offices and the Virginia Commonwealth University School of Dentistry. The outcome assessor …

Culturally Relevant Coping Strategies Within Bicultural Latine College Students In The Face Of Anti-Immigrant Sentiment And Policy, Cindy M. Hernandez

Theses and Dissertations

Despite their protective potential against anti-immigrant sentiment and policy, the connections between bicultural identity development and culturally relevant coping among temporarily documented Latinx college students remain unstudied. Therefore, this study (a) describes culturally relevant coping strategies used by bicultural Latinx college students, (b) examines the role cultural identity plays in bicultural Latinx college students’ coping strategies, and (c) illuminates the role institutional level systems play in liminally-documented college students’ coping with anti-immigrant sentiment and policy. Participants in this study included 16 Latine college students (M_age = 21.19, SD = 3.21) with DACA (n = 14) or TPS (n = …

Less Water, More Holy: Tools For Sustainable Ablution, Faheem Khan

Theses and Dissertations

Prayer is an important part of life for many people, whether it takes the form of meditation or talking to God. Muslims pray five times a day, and before each prayer, they first clean themselves by performing ritual ablution (wudu). The eight-step purification process of wudu cleanses the body from head to toe. The Hadiths of Sahih al-Bukhari and Sahih Muslim tell us the Prophet Muhammad ﷺ needed just one mudd of water (650ml) to complete wudu, but most people consume many times that amount—four-to-seven liters is more common today.

To visualize and better understand the nature …

Associations Between Years Of Teaching Experience And Classroom Management Practices, Responsivenss, And Acceptability To A Coaching Intervention, Nicole M. Peterson

Theses and Dissertations

This study aimed to bridge the research-to-practice gap related to in-service supports and professional development by identifying factors associated with teacher use of evidence-based classroom management practices and responsiveness to a coaching intervention. Years of teaching experience was identified as a teacher-level intervention determinant with a strong research base in the classroom management literature; however few studies used direct observation of behavior to report difference among teacher behavior. This study used quantitative statistical methods to analyze data from a multi-year parent study investigating the effects of a coaching intervention (BEST in CLASS-Elementary) aimed at increasing the use of evidence-based practices …

Exploring Digital Equity Through Parent Perceptions Of Students’ Use Of 1:1 Devices: A Mixed Methods Approach, Joy Washington

Theses and Dissertations

Over the last two decades, 1:1 initiatives, in which each child in a school building is provided a school-issued device, have increased dramatically around the world. However, the outcomes of such programs are not always clear and studies regarding 1:1 one programs have found mixed results. It is important to ensure that1:1 initiatives are equitable and do not perpetuate the digital divide. Many studies exist that examine use of 1:1 devices in schools from a teacher or student perspective. However, only a few studies examine the experience of 1:1 initiatives from a parent perspective and also focus on equity. The …

Improving Feature Learning Capability And Interpretability Of Unsupervised Neural Networks, Chathurika S. Wickramasinghe Brahmana

Theses and Dissertations

The motivation for this dissertation is two-prong. Firstly, the current state of machine learning imposes the need for unsupervised Machine Learning (ML). Secondly, once such models are developed, a deeper understanding of ML models is necessary for humans to adapt and use such models.

Real-world systems generate massive amounts of unlabeled data at rapid speed, limiting the usability of state-of-the-art supervised machine learning approaches. Further, the manual labeling process is expensive, time-consuming, and requires the expertise of the data. Therefore, the existing supervised learning algorithms are unable to take advantage of the abundance of real-world unlabeled data. Thus, relying on …

Temporal Disambiguation Of Relative Temporal Expressions In Clinical Texts Using Temporally Fine-Tuned Contextual Word Embeddings., Amy L. Olex

Theses and Dissertations

Temporal reasoning is the ability to extract and assimilate temporal information to reconstruct a series of events such that they can be reasoned over to answer questions involving time. Temporal reasoning in the clinical domain is challenging due to specialized medical terms and nomenclature, shorthand notation, fragmented text, a variety of writing styles used by different medical units, redundancy of information that has to be reconciled, and an increased number of temporal references as compared to general domain texts. Work in the area of clinical temporal reasoning has progressed, but the current state-of-the-art still has a ways to go before …

Advancing Forest Structure-Function Relationships: Linking Above- And Belowground Structure To Soil Respiration, Laura J. Hickey

Theses and Dissertations

Variation in the soil-to-atmosphere C flux, or soil respiration (Rs), is influenced by a suite of biotic and abiotic factors, including soil temperature, soil moisture, and root biomass. However, whether canopy structure is tied to soil respiration through its simultaneous influence over these drivers is not known. We assessed relationships between measures of above- and belowground vegetation density and complexity, and evaluated whether Rs is linked to remotely sensed canopy structure through pathways mediated by established biotic and abiotic mechanisms. Our results revealed that, at stand-scale, canopy rugosity–a measure of complexity–and vegetation area index were coupled to soil respiration through …

In each session, participants were given either their own brand of cigarettes or one of the four ECIG conditions: 0 mg/mL …

Childhood Reliquary De Una Catracha/Mexi Entre Nopales, Juliana Bustillo

Theses and Dissertations

Childhood Reliquary De Una CatrachaMexi Entre Nopales is a multisensory based installation consisting of three large and six medium scale mixed media paintings with performance. It is informed by my upbringing in Boyle Heights in the projects during the 90s, followed by East LA in the mid 2000s. It is the reliquary for my discomfort in institutional spaces and why I have found comfort in dystopian-like installations. This is the landscape in which I exist, regardless of where I am now. It is where I place my work. It is the context in which I celebrate the powerful delicacy of …

Once Upon A Time/There Was A Story That Began: Novelty, Endings, And Chronotope In John Barth’S The Tidewater Tales, Zachary K. Gibson

Theses and Dissertations

This thesis examines the use of frame tales, genre blending, multi-voiced narration, and circular structure in John Barth’s 1987 novel, The Tidewater Tales. It tracks the isomorphy of Barth’s general aesthetic project, set forth in his essays, “The Literature of Exhaustion,” “The Literature of Replenishment,” and “Very Like an Elephant: Reality Versus Realism,” onto the theoretical aesthetics of Russian philosopher Mikhail Bakhtin. Both Barth and Bakhtin praise the novel its omnivorous capability to accommodate, and juxtaposes conflicting genres against one another; they each see the novelist as an “arranger” or “orchestrator,” who reassembles pre-existing forms to make them …

An Exploration Of Differences In Veteran Suicidality, Philip A. Weisbrod

Theses and Dissertations

Suicide is an important issue of public health, with Veteran suicide being a somewhat unique sub-populous at high risk. This research aims to explore the factors involved in Veteran suicidality that may raise or lower one’s risk. This analysis was conducted with the National Survey for Drug Use and Health (NSDUH) 2020 (N=1173) dataset through use of Binary Logistic Regression (BLR). The analysis showed that having a Major Depressive Episode (MDE) in the past year was the greatest predictor of increased suicidality, while marriage was the strongest buffer by decreasing the likelihood of suicidality increasing.

Detailing The Genetic And Environmental Influences Shared Between Conventional And Electronic Cigarette Use Across Measures Of Initiation And Past 12-Month Use, James Clifford

Theses and Dissertations

Introduction. Tobacco use is a public health crisis with nearly 500,000 Americans suffering premature mortality attributable to tobacco use in 2014. New development efforts have created new nicotine delivery systems whose health consequences are not yet fully understood such as electronic cigarettes (ECIG). It is possible there are shared genetic and environmental factors that influence an individual’s liability to initiate cigarette (CIG) or ECIG use, as both systems are designed to deliver nicotine.

Methods. Four study designs were used to resolve the genetic and environmental influences that underlie CIG and ECIG initiation. A twin study, scoping review, genome-wide association study …

The Lived Experiences Of Higher Education Academic Advisors With Counseling Degrees In Addressing Their Role In Student Success, Shajuana Isom-Payne

Theses and Dissertations

The purpose of this research study was to examine the lived experiences of academic advisors with a counseling degree in addressing their role in student success. If student retention rates are not addressed, higher education institutions are at risk of losing students, which is costly to the institution and the student (Himes, 2014). Most college students are in a state of change and need academic advising support to achieve success during a college transition (Tinto, 2012). Academic advisors can assist students in finding the right career for students’ specific strengths. Academic advisors with counseling degrees address advising through the lens …

Snapshots Of A Fictional Past: Photographic Nostalgia In The Early 20th Century Art Novel., Harry A. Jones Iv

Theses and Dissertations

In this dissertation I argue that the proliferation of a mass codependent relationship with nostalgia in the twentieth century shares a parallel history with the widespread adoption of the reproducible image being used by collective audiences as a supplement for natural memory, or what Proust names “voluntary memory.” This conflict between nostalgia-hungry consumers and artists inspired groups such as Alfred Stieglitz’s Photo-Secessionists and artistically minded authors like Henry James, who employed increasingly complex photographic and literary practices to resist the images’ tendency to debase the aesthetic quality of their own work. Authors such as Marcel Proust and William Faulkner used …

Estimating Weighted Panel Sizes For Primary Care Providers: An Assessment Of Clustering And Novel Methods Of Panel Size Estimation On Electronic Medical Records, Martin A. Lavallee

Theses and Dissertations

Primary Care is on the frontlines of healthcare, thus they see the most diverse set of patients. In order to achieve high functioning primary care, a practice must establish empanelment, the pairing of patients to providers. Enumeration of empanelment, or estimating panel sizes, helps ensure that the demands of the patients demand the supply of providers and optimize the balance of primary care resources to improve quality of care. Further we can adjust panel sizes by using patient-level data on healthcare utilization and complexity extracted from the electronic medial record to determine the amount of care or burden of work …

Machine Learning (Ml) - Assisted Tools For Enhancing Security And Privacy Of Edge Devices, Santosh Kumar Nukavarapu

Theses and Dissertations

The rapid growth of edge-based IoT devices, their use cases, and autonomous communication has created new challenges with privacy and security. Side-channel attacks are one of the examples of security and privacy vulnerabilities that can cause inference at Internet-Service Provider (ISP) and local Wi-Fi networks. Such an attack would leak user’s sensitive information such as home occupancy, medical activity, and daily routines. Another example is that these devices have weak authentication and low encryption standards, making them an easy target for malware-based attacks such as denial of service or launching other network attacks using these infected devices. This thesis dissertation …

Mathematical Models Of Infection Prevention Programs In Hospital Settings, Kelly A. Reagan

Theses and Dissertations

Hospitals play a vital role in providing for the healthcare needs of a community. Patients can develop hospital-acquired infections (HAIs) during their hospitalization due to exposure to foreign bacteria, viruses, and fungi. Infection prevention programs target and reduce HAIs, but implementing the infection prevention programs often comes with a cost. The goal of my research is to use mathematical models to quantify the impact of infection prevention programs on cases of HAIs and total healthcare costs. First, I use a Markov chain model to quantify how one infection prevention program reduces general HAIs in the hospital. Then, I calculate the …

Improving College Students’ Views And Beliefs Relative To Mathematics: A Systematic Literature Review Followed By A Multiple Case Mixed Methods Exploration Of The Experiences That Underpin Community College Students’ Attitudes, Self-Efficacy, And Values In Mathematics, Marquita H. Sea

Theses and Dissertations

Mathematics is particularly important due to its relevance in our daily lives. It is a general requirement throughout schooling. Unfortunately, many students openly declare negative views/beliefs regarding math in their personal and academic lives. These in turn, negatively influence students’ achievement related behaviors and outcomes. First, a systematic literature review was conducted to determine what types of studies/initiatives have aimed to enhance students’ views/beliefs relative to mathematics, including domain general and specific perceptions of math as well as their judgements of who is successful in mathematics and if they themselves can be successful. Specifically, the review centered on the components …

Processes Underlying Black American College Students’ Mental Health: Examining The Roles Of Mental Health Literacy, Ethnic-Racial Identity, And Mental Health-Related Behaviors, Chloe Walker

Theses and Dissertations

Addressing the mental health of college students is a persistent and increasing priority (Auerbach et al., 2018), especially among Black American individuals. Given prevalent mental health disparities, it is critical to understand the association between Black American emerging adults’ mental health literacy (MHL) and mental health outcomes including promotive mental health-related behaviors (MHRBs) and symptoms (i.e., anxiety and depressive symptoms), and the modifiable underlying factors that inform them. Guided by the Theory of Planned Behavior (Ajzen, 1991) and the Identity-based Motivation theory (Oyserman & Yoder, 2007), the present study aimed to examine the relation between mental health literacy and mental …

Family Relationships And Academic Performance Via Belongingness Among Cuban Medical Students: Examining Family Legacy And Sex As Moderators, Maria J. Cisneros-Elias

Theses and Dissertations

Medical diplomacy is a foundational part of Cuban domestic and foreign policy (Feinsilver, 2010). Cuba has an abundance of doctors, encouraged by the country’s free medical education program (Hand et al., 2020), and has made a significant impact with its well-established healthcare system, provision of healthcare for all of its citizens, and healthcare support internationally. The current study aims to focus on processes underlying Cuban medical students’ academic performance, as they are a critical component of this successful system, and a population that has received limited empirical attention. Thus, the current study used path analyses to examine the relations between …

Metamosque – Envisioning The Mosque As A Virtual Public Space, Alaa Albarazy

Theses and Dissertations

Historically, the mosque was not only a space for a communal prayer but also a place for building a community. Today, however, with conflicts and diseases fragmenting society, people are less able to gather physically in large spaces. Out of necessity, people rely on technology to get together and interact virtually. In this context, my research challenges the notion of the mosque as a physical space, proposing, instead, its extension into virtual space. Recent global events pose the question: Can the metaverse offer an opportunity for the mosque to reassert itself as a public space. I propose that a MetaMosque …
