An Evaluation Of Cancer Nurse Providers’ Implementation Of The 2018 Commission On Cancer Survivorship Care Plan Requirement, Angelia Natascha Drake

Electronic Theses and Dissertations

There are apparent problems and fragmentation in the health care delivery system across all specialties, specifically oncology. Oncology is an area within the health care system that has an exponential growth of patients. The incidences of newly diagnosed cancer patients are increasing annually, and the improvements in cancer treatments allow patients to live beyond cancer, resulting in an increased volume of survivors annually as well. These increases place an incredible demand on our health care system, including, but not limited to, primary care physicians and specialists such as medical oncologists. With these increases, there is still an evident gap within …

Student Perceptions Of The Effects Of The Modern Educational Reform Movement On The Concept Of The Whole Child, Edward Theodore Knight

Electronic Theses and Dissertations

As a robust public education system is critical to the future of the U.S. democracy, efforts to improve or reform education have been prominent since its inception. Unfortunately, recent strategies to improve academic achievement have not been successful, and unintended consequences were noted for both students and staff. A specific issue related to modern reform was the construct that the focus on the whole child was disappearing as educators focused solely on the cognitive aspects of their students. The purpose of this study was to examine the perceptions of recently graduated high school students in an effort to determine if …

Positive Body Image And Cognitive Processing Style, Brittney Dumas

Electronic Theses and Dissertations

Social media use among young people is ubiquitous and has been associated with body image concerns. Though prior work has overwhelmingly focused on “screen time,” increasing evidence highlights the role of subjective social media experiences in driving this association, rather than mere frequency of use. In the current study, body appreciation was tested as a trait-level variable that may protect women from the negative impact of appearance-focused fitspiration images, which have become common in social media platforms. Appearance schema activation and appearance-related self-discrepancy were examined as two social-cognitive processes in which self-protective tendencies may emerge. Fitspiration exposure predicted appearance schema …

Policy Development: Stress Management And Critical Incident Debriefing, Karen Loraine Hasie Rowland

Electronic Theses and Dissertations

Abstract Workplace stress and associated disorders (occupational burnout, compassion fatigue, secondary traumatic stress, critical incident stress, posttraumatic stress disorder, etc.) disproportionately affect healthcare workers, especially those working in critical care and emergency environments. The financial cost of stress related after-effects experienced by health care workers exceeds $191 billion each year and includes the cost of associated decreased quality of patient care, missed diagnoses, medical errors, and sentinel events leading to patient disablement or mortality. Mental health interventions such as stress management education and critical incident debriefings have been proven effective in reducing workplace stress and building personal resilience. A gap …

Mineralogical Restrictions On Porosity In The Taylor Sand Of The Cotton Valley Group, Northern Louisiana Salt Basin, Claiborne Parish, Louisiana, Kaleb C. Mcclain

Electronic Theses and Dissertations

The Cotton Valley Group has been targeted for hydrocarbons since the 1940s. However, the reservoir was initially considered uneconomical to drill due to its low permeability and porosity. Since then, recent technological advances in hydraulic fracturing have allowed the Cotton Valley Sandstone members to become prolific, profitable plays, renewing interest in drilling and exploration across the northwest/northern Louisiana region.

In this research, mineralogical restrictions on the porosity in the Lower Taylor Sand of the Cotton Valley Group were studied from core (10,035’ft/3,059m -10,150’ft/3,094m) from Blackburn Field, northwest Claiborne Parish. Twelve samples were taken at intervals throughout the Taylor Sand, starting …

Challenges Of Pastoral Leaders: Maintaining Resilience While Contemplating Transitioning Out Of Ministry, Benjamin A. Griffin

Electronic Theses and Dissertations

Abstract

This study was based upon 40 years of observation of pastoral leaders who faced challenges that tested their resilience to remain in or transition out of full-time ministry. Those who were fortunate to navigate their way through these challenges were resilient in ministry or were able to move forward by becoming bivocational. Some went back to school and got secular degrees and sought jobs outside of their calling. While facing career identity challenges, pastors feared their ministerial skills were less viable in a secular context and were reluctant to make a transition. This study aimed to understand their resilience …

Machine Learning Applied To Colloidal Properties Of Perfluorocarbon Nanoemulsions For Imaging In Ards/Ali, Marco Hosfeld

Electronic Theses and Dissertations

Acute Respiratory distress Syndrome (ARDS) and Acute Lung Injury (ALI) are inflammatory lung pathologies consisting of non-hydrostatic pulmonary edema leading to hypoxia and impaired gas exchange in the lungs. ARDS/ALI is both difficult to study and treat as it is not in itself a specific pathology but rather a syndrome consisting of many pathologies that vary case by case. It is, however, consistently characterized by an explosive acute inflammatory response in the lung parenchyma leading to hypoxia. Although time has seen to an increase in the understanding of ARDS/ALI, the mortality rate remains in the range of 30-50%. For these …

Radiosonde High Altitude Measurements Of Radiation Levels And Cosmic Ray Events, Ayodeji Opeyemi Akinuliola

Electronic Theses and Dissertations

Just above us, cosmic rays are hurtling in from space. These fast moving particles crash uncontrollably into molecules in the atmosphere, causing spontaneous decays of these particles. Despite the fact that we are broadly shielded from this radiation on earth, these particles can still disturb humans and electronics alike. Therefore, this research focuses on expanding the use of long-range radio transmitters such as radiosondes to transmit valuable data such as cosmic ray flux, geographical position, atmospheric temperature, pressure, etc. This can improve real-time radiation monitoring for aviation industry crew and passengers working in potentially higher radiation environments. On March 11, …

Detecting A Heterogenous Sample Of Pigmented Melanoma Cell Lines Using Photoacoustic Flow Cytometry, Margaret Cappellano

Electronic Theses and Dissertations

Metastatic melanoma is the deadliest form of skin cancer, which is in part, attributed to its rapid aggression and lack of response to typical treatment methods. There are far too often cases where a lymph node biopsy does not detect the severity of the cancer, which in turn causes a lack of diagnosis until a mass can be visually detected on a scan, such as a PET, CT, or MRI. Once visible on a scan, the cancer is too progressive for successful treatment. To avoid this, we investigated how a blood sample can be used to negate a missed diagnosis, …

Quantification Of Persistent Organic Pollutants In Various Matrices Using Stir Bar Sorptive Extraction And Isotope Dilution Mass Spectrometry, Weier Hao

Electronic Theses and Dissertations

A method was developed to quantify persistent organic pollutants (POPs) in a wide range of matrices including wastewater, dietary supplements, and human whole blood using stir-bar sorptive extraction, GC-MS/MS, and isotope dilution mass spectrometry (IDMS). The method enabled accurate, precise, sensitive, and efficient quantification of POPs in these matrices. Compared with calibration curves, IDMS provided measurements with a higher level of accuracy and precision, especially at lower measured concentrations. The use of GC-MS/MS enabled a lower limit of quantification compared with GC-MS. A reverse-IDMS method was performed to further eliminate biases from the labelled concentrations of the commercially available standards. …

A Theoretical Framework For Effective Education In Rural High-Poverty Schools, Harley Ramsey

Such leaders honor student and family voices and actively seek to understand and respond to their lived realities. They …

Diagnosis Of Melanoma Disease State From Patient Blood Samples Using Photoacoustic Flow Cytometry, Jacob Salvatore

Electronic Theses and Dissertations

Approximately 1 in 50 Americans develop melanoma in their lifetime. Early detection of melanoma is pivotal to the survival of the patient, with a 99% survival rate for 5 or more years after an early diagnosis. Metastasis, or the spread of cancer, increases the chances of cancerous growth in other parts of the body. In this study, we propose the use of photoacoustic flow cytometry as a diagnostic of patient disease state, by closely monitoring the amount of circulating melanoma cells (CMCs) in a patient’s blood before and after chemotherapy treatments. Using this patient data, we were able to make …

Characterizing The Dormancy And Repair Of A Circumneutral Passive Remediation System Receiving Iron And Sulfate-Rich Amd, Garrett Struble

Electronic Theses and Dissertations

The Wingfield Pines remediation system is a ~20-acre circumneutral, gravity-fed system constructed in 2009 to passively remediate Fe from an ~2000 gallon/minute effluent. In 2017, a fracture to the system’s underground cavern caused the AMD effluent to bypass the system, flowing directly into Chartiers Creek and leaving the system decommissioned between 2017-2019. Soil slurry and water samples were collected in the weeks prior to the system’s reinstalment in September 2019 through January 2020 in order to determine the effect of the repair on remediation efficiency and microbial community composition. This study acted as the first to describe the temporary decommissioning …

Feminine Discursive Authority Through Symbolism, Allegory And Exemplum: A Study Of Christine De Pizan, A Rhetor Of The Late Middle Ages, Kathleen Burk

Electronic Theses and Dissertations

Rhetorical studies are deeply concerned with the way that human beings use language and symbols to interact and persuade others to follow a particular point of view, or plan of action. In the male dominant culture of 15^th century France, Christine de Pizan recognized the limitations of speaking as a woman in her own voice. Therefore, she directed her voice through a cadre of allegorical divine beings, most of whom were women. These allegorical mentors held the divine authority to profess the virtue of women, as Christine, the narrator, humbly listened. This was a time in history when few …

Communication As Change: Marshall Mcluhan And A Transformation Model Of Communication, Lane Grafton

Electronic Theses and Dissertations

The work synthesizes Marshall McLuhan’s transformation model of communication with a trivium-based educational model and challenges the modern-day position of unreflective mediated communication. McLuhan’s transformation model demonstrates that communication is more than the transfer of content; rather, it is a transformation of perception. This work broadens the analysis and suggests that figure and ground relationships are integral to seeing the whole of media transformations. Through figure and ground relationships, communication unfolds as a study of perceptual change. The work explores perceptual change within the context of McLuhan’s conversion to the Catholic Church and underscores the importance of a unified mind …

An Investigation Of Barriers And Facilitators To Living Kidney Donation, Rachel E. Crenshaw

Electronic Theses and Dissertations

There is strong interest in increasing living kidney donation, as the need for kidney transplants is quite high. Although previous studies outline some barriers and facilitators associated with donating, living kidney donation comprises only a small percentage of overall kidney transplants and thus further research on factors influencing the decision to donate is needed to find ways to increase the donor pool. Ten semi-structured interviews of living kidney donors were completed and analyzed for common themes that either support the current literature or surface additional barriers and facilitators. In addition, a systematic review and analysis of social medial support groups …

Covid-19 Serological Diagnostic Development Using A Sars-Cov-2 Rbd Foldon Fusion, Joey Emery Breckenridge Jr.
