A Holistic Quality Management Model For Optimization Of Quality Assurance In Manufacturing, Devon Blakeney Clark

Theses and Dissertations

Quality Management (QM) is essential in manufacturing to ensure products are consistent and functional every time. Consumers expect high quality products that last, and industries unable to accomplish this are destined to fail. Therefore, product quality has always been at the forefront of manufacturer decision making, though it is normally viewed as a given more than as a goal. This means that businesses want quality because it is needed for their survival, but there has not been consideration for how to incorporate innovation into this essential field. Quality needs to be viewed holistically with regards to all manufacturing factors that …

The Role Of Telehealth And Obstetrics Capacity On Maternal Health Care: A Mixed Methods Approach, Shanikque L. Barksdale

Theses and Dissertations

Background: The United States (US) is experiencing a maternal health crisis, with rising severe maternal morbidity and mortality rates and persistent racial, ethnic, and geographic disparities. While telehealth can address access challenges, there is limited evidence of its impact on access to maternity care and outcomes among rural and minoritized communities. The overall objective of this study was to analyze the disparities in maternal outcomes and user satisfaction by hospital-based telehealth and obstetric care availability.

Methods: A convergent parallel mixed methods approach was used. A multinomial logistic regression was used to analyze whether the changes in the proportions of hospitals …

Perspectives From Caregivers For Children With Retinoblastoma: Psychosocial Concerns And Genetic Counseling, Kayla Marie Lashinger

Theses and Dissertations

Caregivers play a vital role in the care of children affected with retinoblastoma as most cases are diagnosed before the age of five years old. While previous studies have explored the psychosocial needs of caregivers of children with pediatric cancer, these have not specifically focused on retinoblastoma in the United States (US). Prior research identified the profound emotional burden in terms of depression, anxiety, guilt, isolation, and loneliness experienced by caregivers. Given previous findings and the National Cancer Institute’s recommendation for genetic counseling and testing for all individuals affected with retinoblastoma, this study aimed to assess psychosocial concerns in relation …

Action Research On Instructional Scaffolding In Information Literacy Instruction For Community College Students, Huyen Maluck

Theses and Dissertations

The purpose of this action research was to evaluate the effect of instructional scaffolding on information literacy skills of college students in an English Composition I (ENG 101) course at Urban Community College in the Southeast. Information literacy is defined as a set of skills to recognize an information need as well as locate, evaluate, and effectively use information (American Library Association, 2021). Community college students may have insufficiencies in their information literacy skills due to lack prior information literacy experience in academic libraries or completing research projects (Head, 2013; Hincliffe et al., 2018). I developed an intervention that involved …

Impact Of Equitable Grading Practices On Student Outcomes And Biology Self-Efficacy In A Ninth Grade Biology Class, Laura Boyle

Theses and Dissertations

This action research study, set in a midwestern high school in the United States, was designed to investigate the impact of implementing equitable grading practices in a first semester freshman biology course. Many grading practices commonly used in classrooms in the United States are subjective, can be used to maintain compliance in the classroom, and do not accurately report what students know and can do. Ideas from Critical Race Theory and Bandura’s Self-Efficacy Theory guided this study. Qualitative and quantitative data were collected through pre and post self-efficacy surveys, grading surveys, and semi-structured student interviews, along with quantitative grade data …

The Effects Of Management’S Esg Disclosure Strategy And Voluntary Esg Assurance On Investment Judgments, Macy Knutson

Theses and Dissertations

Many investors desire to integrate a company’s environmental, social, and governance (ESG) performance into their investment decisions. Accordingly, most companies now disclose at least some ESG information in annual sustainability reports. However, little regulation exists over ESG reporting, creating a well-acknowledged agency problem for investors and making trust vitally important to investment. In this study, I examine two mechanisms which may facilitate trust amongst ESG investors: Management’s ESG disclosure strategy and ESG assurance. Contrary to traditional conceptions of persuasion theory, I find ESG investors reduce investment in response to more transparent negative disclosures when the ESG report is not independently …

Implicit Vs. Explicit Approaches When Teaching Reflexive Structures In A Fifth-Grade Spanish Dual Immersion Classroom, Paula Valeria Ward

Theses and Dissertations

Dual language immersion (DLI) students can develop high levels of proficiency in their second language at a young age. However, they often have difficulties with their accuracy using advanced grammatical constructions (Watzinger-Tharp et al., 2018), such as using different verbs tenses or gender and number agreement in speaking and writing (Bateman et al., 2020). The goal of this study is to test whether explicit or implicit instructional approaches are more effective in the teaching of one such grammatical concept, specifically reflexive constructions, in two DLI classrooms. In this research, I investigated results from a five-lesson treatment in a case study …

A Plug-And-Produce Connectivity Framework For Manufacturing Systems, Theodros Abraham Tarekegne

Theses and Dissertations

The Industrial Internet of Things (IIoT) movement has birthed technologies that enable the fusing of physical and digital environments. However, the extensive number of available options for industrial communication and data formatting has remained a barrier to achieving digital knowledge synonymy in industry. There have been previous attempts to establish standards for industrial connectivity and communication, but legacy machines, as well as custom and non-proprietary devices, still face issues communicating data with other manufacturing equipment. To address these challenges, the Industrial Internet of Things initiative has led to the creation of the Plug and Produce (PnP) concept to facilitate the …

In The Search Of Cosmopolitan Literacies: A Case Of Formerly Expatriated Language Teacher, Asiye Demir

Theses and Dissertations

Cosmopolitanism refers to becoming a world citizen who can live harmoniously with different cultures. Today, our classes in the United States have become diverse daily. While we teach students who can speak more than one language, our teachers are primarily monolingual and monocultural. Hence, teachers who can speak multiple languages are celebrated in the system (Pacheco et al., 2019). Expatriation refers to teacher mobility that can entail learning other languages and being exposed to different cultures. Expatriation, as a form of travel, is an essential construct for cosmopolitan literacies because cosmopolitan dispositions can be developed through traveling (Molz, 2006). Thus, …

Student Experiences With Self-Determination And Agency: Centering Disabled Voices Through Photovoice, Rebecca Boineau Smith Hill

Theses and Dissertations

Young adults with intellectual and developmental disability (IDD) are less likely than young adults without disability to be employed, enrolled in postsecondary education, or live independently after high school (Lauer & Houtenville, 2017; Newman, et al., 2011). Self-determination, or the freedom to act as the primary causal agent in one’s life (Palmer & Wehmeyer, 1998), is a well-documented component of enhanced quality of life (Shogren et al., 2017) and a predictor of postschool success (Mazzotti et al., 2021; Test et al. 2009) for students with disabilities. People with IDD are less self-determined than their nondisabled peers, and often less self-determined …

Native American Nationalism: Chickasaw Identity And The Music Of Jerod Impichchaachaaha' Tate, Austin Davis

Theses and Dissertations

Native American nationalism in classical music has yet to be seriously researched and is not taught in music academia. One of the more well-known contemporary Native American composers is Chickasaw composer Jerod Impichchaachaaha’ Tate (b. 1968). Throughout his career, Tate has explored and expressed his identity as a Native American and Chickasaw citizen through his music. As a result, his compositional output is a rich resource for examining what Native American nationalism in classical music looks like and how it is utilized in his works.

In this document, I analyze three of Tate’s pieces written for orchestra: Tracing Mississippi, Ghost …

Maternal-Child Cortisol Attunement Differs In Preschoolers With Autism, Fragile X Syndrome, And Neurotypical Development, Rachel Hantman

Theses and Dissertations

Early maternal-child attunement sets a critical foundation for later social development. While maternal and child cortisol attunement in neurotypical (NT) development has been clearly established, little research has examined these relations in neurodevelopmental populations, such as those with autism spectrum disorder (ASD) and Fragile X Syndrome (FXS). Given their elevated-risk for disrupted maternal-child attunement and given elevated stress and dysregulated cortisol patterns in both children with ASD and FXS and their parents independently, this is a critical gap. This study addressed this gap in the literature by examining early maternal-child cortisol attunement in 97 mother-child dyads (_nNT = …

Coastal And Inland Flooding - From Advanced Hydrodynamics And Data-Driven Modeling To Multi-Variate Coastal Vulnerability Assessment, Ahad Hasan Tanim

Theses and Dissertations

Flood risks in coastal and inland areas have historically been underestimated and underpredicted, resulting in increased flood damage and loss of human life. Flood risk under climate change and sea level rise will disproportionately impact low-wealth and marginalized communities, as they are often located in areas with less flood protection and have limited resources to adapt to the impacts of flooding. The systematic workflow of the life cycle of FRM is frequently disengaged in the current state of flood hazard assessment with system vulnerability assessment. This research aims to improve the life cycle of FRM by incorporating flood observation, monitoring, …

Use Of Improvement Science To Build The Instructional Capacity Of Faculty In A Community College, Marianne Yohannan

Theses and Dissertations

Up to 78% of Science, Technology, Engineering and Mathematics (STEM) students experience poor academic achievement as defined by course grades of D, F and W in college. Students entering these fields are often not prepared (Chen & Soldner, 2013) and struggle to succeed in gateway STEM courses, with one-third of them possibly failing (Freeman et al., 2011). The success rates are lower among first-generation, low-income, and underrepresented minoritized groups (Doerschuk et al., 2016). At Tri-County Technical College, 30-40% of introductory biology students are unsuccessful and receive low grades (Institutional Research, n.d.). Low academic achievement has a huge impact on our …

Associations Between Infant Vagal Regulation, Early Social Communication, And Socidemographic Risk, Tessa Djiko

Theses and Dissertations

Respiratory sinus arrythmia (RSA), a measure of parasympathetic nervous system activation, has been linked to socioemotional and language development (Porges, 2007; Thayer & Lane, 2000). Children diagnosed with autism spectrum disorder (ASD) show lower RSA (Patriquin et al., 2011) while both children with ASD and children from lower SES backgrounds show differences in early social-communication development (Jones-Mason et al., 2018). However, little is known about interactions between sociodemographic risk and physiological regulation within the context of ASD and social-communication development. The present study addresses this gap by examining the relationship between RSA (as indexed by RSA suppression and resting-state RSA), …
