Social Support Among Family Caregivers Who Attend Hospice Virtual Group Counseling Sessions: Facilitators And Barriers To Attending These Sessions, Katherine M. Hertzfeld

Dissertations

The National Hospice and Palliative Care organization has identified that a majority of its estimated 1.43 million patients in 2016 were cared for by family members. Studies show that these family caregivers often suffer poor health outcomes if they do not receive enough social support during the grieving process following their family members' death. Attending group counseling sessions can provide social support if the family caregiver is willing to attend. The Transtheoretical Model (TTM) indicates changes in health behavior and can facilitate individuals to attend group counseling sessions. The purpose of this evidence-based practice project is to identify the level …

Use Of Comprehensive Care Coordinator Telephonic Outreach To Increase Colorectal Cancer Screening In Primary Care, Sarah N. Klotz

Dissertations

Colorectal Cancer (CRC) is one of the most commonly diagnosed cancers in the United States. More than 140,000 patients in the United States will be diagnosed with CRC in 2020. Despite clear benefits to timely CRC screening only 63% of eligible patients in the United States are screened appropriately. The Target Health System has identified that under-screening for CRC posess a significant patient care outcome and quality reimbursement concern.

Impact Of Diabetes Self-Management Education On Adults With Diabetes And Mental Illness, Brooke Tullis

Dissertations

Approximately 9.4% of the population of the United States, or 30.3 million Americans, has diabetes mellitus. Diabetes is the seventh leading cause of death and places a significant financial strain on the healthcare system with approximately $327 billion in estimated expenditures. In Ohio, 13.5% of the population has diabetes, which represents a 4.1% increase above the national average. Additionally, individuals with mental illness are at an increased risk for diabetes due to lower self-efficacy and limited performance of self-care activities compared to the general population. This results in poor glycemic control and leads to an increased risk for diabetes complications. …

An Exploration Of The Two-Generation Approach For Single Mother Degree Or Certificate Attainment, Chiquila N. Dolison

Dissertations

Investments in student support services that encompass single mother needs can influence postsecondary degree attainment and increase earning potential that can lead to benefits, including economic self-sufficiency and poverty alleviation (Alssid et al., 2002; Gault, Milli, & Cruse, 2018; Gault, Noll, & Reichilin, 2017; Graham & Bassett, 2011; Kruvelis, Cruse, & Gault, 2017). Despite the benefits of single mothers' college degree attainment, they are least likely to earn them (Gault et al., 2018). In the United States, 8% of single mother undergraduates earn a postsecondary degree within six years of enrollment compared to the 49% of women who are not …

Synthesis And Self-Assembly Of Amphiphilic Block Copolymers For The Fabrication Of Non-Spherical Polymersomes, Tamuka Chidanguro

Dissertations

Polymersomes, also known as polymer vesicles, have gained a lot of interest over the past two decades. These hollow spherical systems are made via the self-assembly of amphiphilic block copolymers and have found use in a range of areas from drug delivery, to cellular models, to nanoreactors. Their hollow nature allows them to carry hydrophilic cargo in their inner compartment and hydrophobic cargo in their membrane. Over the last decade, increasing efforts have focused on controlling the morphology of polymersomes.

The Power Of Sulfur: A Study Of An Isothiocyanate Chiral Derivatizing Agent, Thioamide Based Chiral Solvating Agents, And The Geometry Of Sulfonamides, Emily B. Crull

Dissertations

This three-part dissertation is connected by the thread of utilizing sulfur-based functional groups, hence the power of sulfur. The first project was the development of a pentafluorobenzene based isothiocyanate chiral derivatizing agent (CDA), a class of compounds that differentiate enantiomers through covalent bond formation. This project, which was addressed using a combination of synthetic and computational methods and NMR analysis, gave rise to an CDA that was highly selective for amines and computationally predictable. Branching off of that, the second project demonstrated the use of two thioamide chiral solvating agents (CSAs), which had never been reported as a core functional …

A Component-Wise Approach To Smooth Extension Embedding Methods, Vivian Montiforte

Dissertations

Krylov Subspace Spectral (KSS) Methods have demonstrated to be highly scalable methods for PDEs. However, a current limitation of these methods is the requirement of a rectangular or box-shaped domain. Smooth Extension Embedding Methods (SEEM) use fictitious domain methods to extend a general domain to a simple, rectangular or box-shaped domain. This dissertation describes how these methods can be combined to extend the applicability of KSS methods, while also providing a component-wise approach for solving the systems of equations produced with SEEM.

On The Treatment Of Bilinear Forms Involving Matrix Functions As Perturbations Of Quadratic Forms, Keelia Altheimer

Dissertations

Optimizing the approximation of bilinear forms using a one-sided perturbation, where the computation of the approximate solution is generated faster while using less storage or reusing information is possible. Standard methods for approximation like Lanczos and others exist; however, separating the work a little bit and having the bilinear form relate to the quadratic form can yield a more efficient algorithm. When we have an application where the needs are different, it is helpful to understand how the processes like symmetric Lanczos and unsymmetric Lanczos relate to one another so that we can find a way to break things down …

Data-Driven Approaches To Complex Materials: Applications To Amorphous Solids, Dil Kumar Limbu

Dissertations

While conventional approaches to materials modeling made significant contributions and advanced our understanding of materials properties in the past decades, these approaches often cannot be applied to disordered materials (e.g., glasses) for which accurate total-energy functionals or forces are either not available or it is infeasible to employ due to computational complexities associated with modeling disordered solids in the absence of translational symmetry. In this dissertation, a number of information-driven probabilistic methods were developed for the structural determination of a range of materials including disordered solids to transition metal clusters. The ground-state structures of transition-metal clusters of iron, nickel, and …

Structural Origin Of Thermal, Mechanical Properties And Morphological Behaviors Of Semiconducting Polymers, Song Zhang

Dissertations

The past decades have witnessed a surging exploration of semiconducting polymers for the application of wearable and flexible organic electronic devices. Despite the increased amounts of molecular engineered polymers and their much-improved electrical performances, a systematic study of the structure-thermal/mechanical property-morphology relationship of semiconducting polymers is still less investigated.

To understand the thin-film mechanical properties, a pseudo-free standing tensile tester was self-built and utilized to obtain their real-time stress-strain behaviors through uniaxial stretching on top of the water surface. It also enables the first quantitative measurement of fracture energy on ultrathin polymeric films. Through multiple mechanical testing methods (i.e., strain-rate …

Efficient Denoising Of High Resolution Color Digital Images Utilizing Krylov Subspace Spectral Methods, Eva Lynn Greenman

Dissertations

The solution to a parabolic nonlinear diffusion equation using a Krylov Subspace Spectral method is applied to high resolution color digital images with parallel processing for efficient denoising.

The Relationship Between School Principals’ Servant Leadership Attributes And Teacher Morale, George Larry Johnson

Dissertations

Teacher morale in schools has a profound impact on the school and the level of student achievement. Low teacher morale cases high teacher turnover and causes teachers to be resistant to change, while schools with high teacher morale boast better teacher attendance, higher student achievement, and a sense of cohesiveness in the school. A principal’s leadership style has a significant effect on the level of teacher morale in schools. Servant leadership is a theory of leadership, first developed by Robert Greenleaf, where the leader leads by serving and puts followers first. Servant leadership theory has proven to be an effective …

Comparison Of Manipulatives Effect On Academic Achievement In Preschool Math, Ashley Stewart

Dissertations

Students in the United States tend to possess poor academic performance in mathematics compared to other developed countries. Despite the increased preschool enrollment and attendance, there are academic disparities among preschool students. Earlier exposure to mathematical concepts can positively affect student outcomes. Research supports the idea that early exposure and mastery of patterning skills and non-symbolic quantity knowledge are trajectories of math academic achievement during elementary and middle-level grades (Rittle-Johnson, Fyfe, Hofer, & Farran, 2016). Students who begin with mathematics deficiencies, without proper intervention, tend to continue to lack understanding of foundational math skills that are essential for proficiency in …

Decision-Making By Community College Administrators On Satellite Campuses Of Mississippi Community Colleges, Raymunda Barnes

Dissertations

According to Schindler (1952), the first off-site community college campuses were not named satellite campuses. They were referred to as “off-campus undergraduate divisions of higher institutions.” Over time, the satellite campus has evolved into a critical part of the higher education landscape. As a result, the administrators that are assigned to manage satellite campuses are responsible for making decisions that affect college personnel and students who attend the satellite campus. The purpose of this qualitative phenomenological study was to examine administrative decision-making on satellite campuses of Mississippi community colleges by satellite campus administrators. Eight satellite administrators participated in this study. …

Higher Education Business And Technology Leaders’ Behaviors That Drive Outcome Alignment, Katherine Lynch-Holmes

Dissertations

Higher education institutions (HEIs) face unprecedented challenges, including capacity alignment, financial sustainability, and even public confidence (Grajeck & Brooks, 2020; Grawe, 2019; Oblinger, 2019; Simone, 2020, Wheeler, 2020, Witt & Coyne, 2019). Financial challenges force HEIs to reduce costs by making decisions like cutting programs, laying off staff or merging institutions to reduce operating costs (Chen et al., 2019; Sellingo, 2017; Witt & Coyne, 2019). Higher education leaders (HELs) must act as trusted partners and broker technology to align processes, support, and outcomes (Luftman 2000; Petkovics, 2018; Reinitz, 2019). Unfortunately, higher education’s business-technology (BITA) alignment remains lower than other national …

Elucidating The Role Of The Msaabcr Operon In Persister Cells Formation And Stress Response In Staphylococcus Aureus, Shanti Pandey

Dissertations

Staphylococcus aureus is a major human pathogen that causes lethal systemic conditions such as infective endocarditis, osteomyelitis, sepsis and pneumonia. Chronic in nature, these diseases are often refractory to the antibiotic treatment. Such recalcitrance is mainly caused due to the presence of persister cells, which are a bacterial subpopulation that exhibits extreme, yet transient antibiotic tolerance accompanied by a transient halt in the growth. However, upon cessation of antibiotic treatment, resumption in growth of persister cells causes recurrence of infections and treatment failure, displaying tremendous clinical significance. In this study, we show the involvement of the msaABCR operon in persister …

Atomic Oxygen Resistant Low Earth Orbit Stable Polymer Matrix Composites Employing Phenylphosphine Oxide Epoxy-Amines, Witold Fuchs

Dissertations

Atomic oxygen (AO) attacks polymer matrix composites (PMC’s) on the surfaces of spacecraft in low earth orbit (LEO) and threatens safe spacecraft operation and service life. Incorporating phenylphosphine oxide (PPO) groups into polymer chains offers a self-regenerating method of protection from AO but remains poorly understood. Herein, epoxies containing PPO groups were synthesized with increasing concentrations of phosphorus [P] from 0 to 8 wt % to investigate their AO resistance.
