Erlang-Distributed Seir Epidemic Models With Cross-Diffusion, Victoria Chebotaeva

Theses and Dissertations

We examine the effects of cross-diffusion dynamics in epidemiological models. Using reaction-diffusion dynamics to model the spread of infectious diseases, we focus on situations in which the movement of individuals is affected by the concentration of individuals of other categories. In particular, we present a model where susceptible individuals move away from large concentrations of infected and infectious individuals.

Our results show that accounting for this cross-diffusion dynamics leads to a noticeable effect on epidemic dynamics. It is noteworthy that this leads to a delay in the onset of epidemics and an increase in the total number of people infected. …

Associations Between The Use Of Ssri Medication In Older Adults And Cognitive Decline And Impairment, Paige Jones

Theses and Dissertations

Previous research has indicated that depression is a risk factor for dementia. Since SSRI medication is the most common treatment for depression, it is important to determine if SSRIs are associated with reduced dementia and better cognitive outcomes. Using longitudinal data from the 2004-2014 waves of the Health and Retirement Study merged with the 2005 Prescription Drug Study, we examined potential associations between SSRI and TCA medication and cognitive impairment and cognitive decline. The study population consisted of 1,775 older adults who participated in the PDS in 2005. We found that SSRIs were associated with significantly higher odds of cognitive …

Evaluating Nonlinear Relationships In Sem Models: An Example Of Parameter Estimation And Stability Using Expectancy Value Theory, Steven G. Barth

Theses and Dissertations

In structural equation modeling, relationships between exogenous and endogenous variables are often assumed to be linear though that is not a requirement. A recent trend in modeling latent interactions and moderations has stimulated further inquiry into nonlinear relationships and the analysis techniques associated with those types of models. However, rarely do investigators specify other potential nonlinear relationships such as quadratic relationships. This study explores the potential for quadratic relationships within Expectancy Value Theory when p the impact of high school students’ motivational beliefs on their pursuit of STEM-related activities. Using the High School Longitudinal Survey as a source of information, …

Design Of An Artificial Transcription Factor For Inducing Potent Interferon-Γ Signals, Ashley King

Theses and Dissertations

Cytokines are small immune signaling proteins responsible for cellular communication and their levels are tightly regulated throughout immune recognition and defense. Interferon gamma is a key cytokine responsible for upregulation of antigen presentation and supports the differentiation of pro-inflammatory effector cells. Due to its role in regulation, excess interferon gamma is cleared from the body limiting the success of interferon gamma immunotherapies. This study reports the design and validation of an artificial transcription factor (ATF) that induces endogenous interferon gamma expression. The transcription factor contains zinc finger proteins to recognize the interferon gamma gene and an activation domain to promote …

A Conductor’S Guide To When We No Longer Touch: The World’S First Aids Requiem, Kevin Crowe

An Emic Conceptualization Of Veteran, “You're Either One Of Two Things; You're Captain America Or You're Broken”, Steven Wahle

Theses and Dissertations

The Global War on Terror (GWOT) conflicts have been sustained by an all-volunteer force for over 20 years. There have been no drafts, war bond drives, nor rationing. This is a departure from previous prolonged military conflicts in U.S. history. Volunteers with veteran status are often venerated publicly to express gratitude for their voluntary military service. However, the criterion for veteran status is inconsistent.

In the U.S., former military members tend to be regarded on one of two ends of a spectrum as archetypes in attempts to honor such service. On one end is the veteran hero veteran to be …

Neural Mechanisms Of Estrogen And Inflammation In Female Stress Susceptibility, Samantha Jane Bouknight

Theses and Dissertations

Posttraumatic stress disorder (PTSD) and major depressive disorder (MDD) are highly debilitating psychiatric disorders that notably share stress as an etiological factor. Stress is a common occurrence experienced daily by virtually everyone and, while most people are resilient, a substantial portion of the population exhibit risk factors that yield them susceptible to developing stress-related psychiatric disorders. One prominent factor that has long been known to increase this risk is the female biological sex with women presenting at least twice as often with disorders like PTSD and MDD compared to men. Interestingly, this bias exists distinctly during the reproductive years and …

Effects Of A Classroom Cognitive Apprenticeship On Scientific Reasoning, Student Agency, And Biology Self-Efficacy On Students In High School Biology, Anne Morris Byford

Theses and Dissertations

Students entering high school often bring misconceptions about the nature of science and experimentation with them from middle school. Many also bring a belief that they are not a “science kid” and, therefore, cannot be a strong student in Biology. This belief can lead to a lack of self-efficacy and of student agency in the classroom. Exposure to authentic research experiences has been shown to increase in self-efficacy and scientific reasoning. Typical research experiences have been limited to summers, specialized after school programs and, in many cases, honors students. To circumvent the unequitable access to these experiences and to determine …

Sickle cell disease (SCD) is a group of disorders of the hemoglobin resulting in episodes of chronic pain, pulmonary hypertension, progressive multiorgan damage, risk for stroke, and increased mortality. It is caused by biallelic pathogenic variants in the HBB gene and 1 in 12 African Americans, 1 in 100 Hispanic individuals, and 1 in 30-50 Mediterranean people are reported to be carriers of the disease and have sickle cell trait (SCT). SCD is typically diagnosed through newborn screening; however, when prospective parents are aware of their carrier status, they can conceive via in vitro fertilization (IVF) and have genetic testing …

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 …

Assessing Multi-Annual Phytoplankton Community Compositions And Biomass Across Tidal Creek And Open Water Estuarine Habitats In South Carolina, Shannon Elizabeth Powers

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, …

Field Implementation Of A Stereo Vision System For Rnt And Stress Measurements In Cwr, Brittany Stinson

Theses and Dissertations

The use of Continuous Welded Rail (CWR) provides many advantages to the rail industry compared to the alternatively used jointed-track segments. However, one significant disadvantage is the development of thermal stresses longitudinally in the rail, which is not of concern when expansion joints are used. This is due to CWR’s inability to release thermal expansion in the absence of joints. The Rail Neutral Temperature (RNT) is the temperature at which the rail is in a stress-free state. A desired RNT is calculated based on local climate conditions and CWR installation practices are implemented to set the desired RNT at installation. …

Modulation Of Neurodegenerative Disease Progression By Antioxidant Status, Elena Kelety

Theses and Dissertations

Neurodegenerative diseases, including Amyotrophic lateral sclerosis, Alzheimer's disease, and Parkinson's disease, profoundly impact the brain and nervous system. In 2019, the United States reported the highest global prevalence of neurological disorders. This thesis approaches neurodegenerative diseases by emphasizing the critical role of a well-maintained antioxidant system, its intricate relationship with dietary patterns, and proposes an alternative fate of the antioxidant urate.

Neurodegenerative disease pathogenesis involves a complex interplay of neuroinflammation, mitochondrial dysfunction, misfolded proteins, and oxidative stress. Oxidative stress arises from an imbalance in the antioxidant defense system and the production of reactive oxygen species. Synergistic antioxidant interactions are vital …

Sonic Data: Sonification In James Stephenson’S There Are No Words And David Kirkland Garner’S Red Hot Sun Turning Over, Nathan Lee Tucker

Theses and Dissertations

Sonification, or the transformation of data relations into sound, has inspired composers of orchestral and wind ensemble music over the past several years. Two of the resulting works included there are no words by James Stephenson and red hot sun turning over by David Kirkland Garner. Both works were analyzed, and their histories detailed in this study. Issues in American society and the American South such as gun violence, civil rights, and American Civil War monuments are revealed as inspiration for composers to map empirical processes onto sound. These musical protests against misinformation were shown to illuminate histories and correlations …

The Gendered Patterns Of International Migration Systems: The Role Of Need For Care, Chang-Yi Lin

Theses and Dissertations

The demand for feminized jobs in developed countries—e.g., care, domestic, and entertainment work—has provided women with an opportunity to work abroad independently. However, while numerous studies have discussed gendered opportunities and barriers to women’s migration, few studies have examined these correlates globally. According to traditional gender norms, one such potential barrier is women’s childcare responsibilities at home and, more specifically, the number of children who need to be cared for. Here it is argued that, contrary to men, the higher the number of children who need to be cared for in a given country, the more difficult it would be …

Association Between Autoimmune Diseases And Lymphoma Risk Using The Uk Biobank, Hannah Grace Dice

Theses and Dissertations

Background. Lymphoma is a blood cancer that develops when white blood cells multiply in an abnormal way and collect in the lymph nodes. Autoimmune diseases result when the immune system is overactive, causing it to attack and damage the body’s own tissues. Limited studies have been conducted to investigate the association between autoimmune diseases and lymphoma risk.

Literature review. Based on prior research, six autoimmune diseases (rheumatoid arthritis (RA), lupus, Sjögren’s syndrome, sarcoidosis, Crohn’s disease, and ulcerative colitis (UC)) were examined to better understand their association with lymphoma risk. Prior research has concluded that certain aspects of these autoimmune diseases …

Housing Buyouts At The Intersection Of Flooding And Toxins: A Case Study Of Cheraw, South Carolina, Victoria Ponds

Theses and Dissertations

As climate change increases extreme weather events, efforts of managed retreat will also increase, particularly through housing buyout programs. The largest scale housing buyout programs are run through the Department of Housing and Urban Development (HUD) and the Federal Emergency Management Agency (FEMA). These buyout programs focus primarily on flood hazards and exclude anthropogenic hazards. This policy is problematic in the modern technological age where compound hazards, including those involving toxin releases, are occurring more frequently. In this thesis, I investigate how disaster policies account for the intersection of these hazards in Community Development Block Grant-Mitigation buyouts in Cheraw, South …
