From Oceans To Public Health: Impact Of Climate Change And Socioecological Factors On Non-Cholera Vibrio Spp., Karlen Enid Correa Vélez

Theses and Dissertations

Climate change-induced stressors, such as temperature, salinity, pH, and wildfire, are contributing factors to the increase in frequency of Vibrio infections, altering Vibrio geographical constraints. At the same time, the expansion of the coastal population is resulting in increased input of treated municipal wastewater into areas that are also experiencing Vibrio proliferation. Given that increases in ocean temperature and sea level coupled with increases in human activity in coastal waters support greater Vibrio-human interactions, it is important to examine factors and mechanisms within this socio-ecological coupled system that may further strengthen this interaction. This study aimed to better understand the …

Infection Intensity And Prevalence From Perkinsus Marinus In The Eastern Oyster, Crassostrea Virginica (Gmelin 1791) And Their Association With Salinity, Temperature, And Sex In South Carolina Estuaries, Deja E. Best

Theses and Dissertations

This project aimed to identify the associations between the infection intensity and prevalence of Perkinsus marinus infection (i.e., Dermo ) in the Eastern oyster, Crassostrea virginica (Gmelin), with extrinsic environmental factors such as changes in salinity and temperature along with oyster host factors such as sex ratio. The objectives of the study were to: (1) identify significant associations between the dependent variables, P. marinus prevalence and infection intensity, in relation to salinity and water temperature which may be affected by climate change; and (2) identify any intrinsic factors related to sex (i.e., male, female, intersex, and indeterminant) that may affect …

Replenishment Of Essential Natural Resources: An Assessment Of The Ability Of Freshwater Algae To Enhance Crop Quality And Soil Health, Lala Christina Ek

Theses and Dissertations

Disregard for soil, an essential natural resource, hinders global food production. Food insecurity is a major concern for both public health officials and environmental scientists due to soil quality decline, pollution, and climate change. Alternatives or targeted additions to chemical fertilizers can bolster soil quality, improve crop yields, lengthen crop shelf life, and mitigate environmental pollution. One potential alternative to chemical fertilizers is replacement of them with biological soil amendments, including algae, to enhance crop growth and improve soil health. Research was conducted at the University of South Carolina-Columbia campus garden to determine impacts of non-toxic freshwater algae on crop …

Transdisciplinary Approaches To Community Engagement, Research Translation And Science Communication Through Application Of The Socio-Environmental Report Card Process And Product In Murrells Inlet, South Carolina, Ekaterina Negodyaeva Altman

Theses and Dissertations

Public health and environmental sustainability are interlinked. Three pillars of sustainable development are society, environment, and economy are supported and reinforced by healthy populations. Balancing these values in a long-term vision and application requires active involvement of communities and stakeholders in decision-making process of management of environmental resources and personal health choices. Transdisciplinary sustainability science provides a framework for addressing complex issues in sustainability and generates actionable knowledge to link science and policy and involved stakeholders in the scientific process. Transdisciplinary research processes use co-design, co-production, and co-implementation framework to create and re-integrate useful knowledge into practice on a local …

Parent Perspectives On Barriers And Facilitators To Optimal Healthcare And Medical Screenings For Children With Down Syndrome In South Carolina, Vinita Oberoi Leedom

Theses and Dissertations

Children with Down syndrome (DS) often have co-occurring conditions affecting vision, hearing, sleeping, and more. Screenings, as recommended by the American Academy of Pediatrics (AAP), can help prevent secondary disability, and allow children to thrive. Studies have evaluated the receipt of recommended screenings, but barriers and facilitators surrounding access to screenings and care have not been described.

Parents of 24 children with DS in SC were recruited through schools and family support groups. One-hour long interviews were conducted in English and Spanish. Information was collected on health, healthcare quality, respiratory concerns, pandemic effects, access to care, and knowledge about AAP …
