Examination And Application Of Body Condition Methods In Cetaceans, Kira Anne Telford Oct 2023

Examination And Application Of Body Condition Methods In Cetaceans, Kira Anne Telford

Theses and Dissertations

Body condition assessments are a valuable tool for evaluating the relative health of a population through various metrics, indexes, or proxies. Long-term data collection can be used to examine the relationship between fluctuations in body condition and natural or anthropogenic drivers. Application of this information is vital for monitoring the success of the conservation management decisions for a species or population. Cetaceans have a variety of methods available to assess body condition, including invasive methods like biopsies and necropsies or observational methods such as photogrammetry. Exploration of the application of these methods in the literature revealed an emphasis on necropsies …

Urban Flooding Accelerates The Affordable Housing Shortage: A Case Study In Columbia, South Carolina, Mary Hannah Lindsay Oct 2022

Urban Flooding Accelerates The Affordable Housing Shortage: A Case Study In Columbia, South Carolina, Mary Hannah Lindsay

Theses and Dissertations

The state of South Carolina stands at the corner where climate change and the housing crisis meet. The affordable housing stock across South Carolina continues to deplete as its major cities experience urban flooding events due to outdated and weakened infrastructure, compounded by an intensification of storm systems brought on by a changing climate. Lower income communities are forced to accept lesser living conditions and less resilient housing options because these options are more affordable. Renters are often met with more challenges when navigating disaster recovery compared to homeowners. Using a case study established in Columbia, South Carolina of the …

Superfund And Society Benumbed: An In-Depth Look At Environmental Justice In South Carolina, Sydney A. Hampton Apr 2022

Superfund And Society Benumbed: An In-Depth Look At Environmental Justice In South Carolina, Sydney A. Hampton

Senior Theses

This thesis investigates the relationship between superfund sites in minority communities and their public health through the lens of social vulnerability. Various demographic parameters were used to assess the risk associated with minority communities and exposure to hazardous waste. After investigating the history of the Environmental Justice movement, three superfund sites of interest in South Carolina, and demographic and public health data; each community was analyzed to determine association between exposure to hazardous waste and minority status. Each examined community exhibited characteristics contributing to heightened social vulnerability, potentially causing increased susceptibility to negative health outcomes from exposure to hazardous waste.

A Spatial Risk Prediction Model For Drug Overdose, Parisa Bozorgi Apr 2021

A Spatial Risk Prediction Model For Drug Overdose, Parisa Bozorgi

Theses and Dissertations

Drug overdose is a leading cause of unintentional death in the United States and has contributed significantly to a decline in life expectancy from 2015 to 2018. Overdose deaths, especially from opioids, have also been recognized in recent years as a significant public health issue. To address this public health problem, this study sought to identify neighborhood-level (e.g., block group) factors associated with drug overdose and develop a spatial model using machine learning (ML) algorithms to predict the likelihood or risk of drug overdoses across South Carolina. This study included block group level socio-demographic factors and drug use variables which …

Corporate Social Responsibility: Examining The Effects Of A Lean And Green Supply Chain On Bottom Line Costs And Market Valuation, Sharon Maskin May 2018

Corporate Social Responsibility: Examining The Effects Of A Lean And Green Supply Chain On Bottom Line Costs And Market Valuation, Sharon Maskin

Senior Theses

This paper examines the link between a firm’s adoption of Corporate Social Responsibility (CSR) practices and the resulting monetary benefits. Specifically, it addresses four major areas of business operations that present great opportunities for supply chain cost reduction and a simultaneous decrease in environmental impact. These four areas include traditional/open-loop supply chains, product packaging waste, pollution at the manufacturing site, and logistics inefficiencies. The paper then identifies several business cases in which companies have addressed several environmental issues and driven down bottom-line costs in each of the four areas through innovation and increased resource productivity. Along with cost benefits, it …

Investigating The Toxicity And Accumulation Of 2,4-Dichlorophenoxyacetic Acid (2,4-D) And Glyphosate In Eisenia Fetida, Caitlin Lazurick, Nicole Lidzbarski, Rachel Owings, Jeff Brotherton, Edna Steele Nov 2017

Investigating The Toxicity And Accumulation Of 2,4-Dichlorophenoxyacetic Acid (2,4-D) And Glyphosate In Eisenia Fetida, Caitlin Lazurick, Nicole Lidzbarski, Rachel Owings, Jeff Brotherton, Edna Steele

Journal of the South Carolina Academy of Science

Glyphosate, the main ingredient in Roundup®, is the most widely used herbicide in the world. It is also used in combination with another effective herbicide, 2,4-D, in the formulation called Enlist Duo®. The EPA approved the use of Enlist Duo® on certain crops including those genetically modified to be resistant to both herbicides. The predicted significant increase in the use of these herbicides raised concerns from the general public because both compounds have been classified as possibly or probably carcinogenic. Since herbicides are applied directly to vegetation, the safety of organisms that come in contact …

Due to the increased prevalence of obesity, non-alcoholic fatty liver disease (NAFLD) has become a major public health problem in the Western world and Asian countries. Approximately a third of the general population in the US has NAFLD. NAFLD includes a spectrum of histological characteristics ranging from simple steatosis to steatohepatitis, fibrosis and cirrhosis and can be characterized into to two major phenotypes: nonalcoholic fatty liver (NAFL) and nonalcoholic steatohepatitis (NASH). Water disinfection byproducts like trihalomethanes can act as crucial risk factors for NAFLD progression. Here I have studied the molecular mechanisms of a water disinfection byproduct, Bromodichloromethane, in induction …

Uptake Of Nanoparticles By Vibrio Gazogenes, Shonda Renee Jones Jan 2016

Uptake Of Nanoparticles By Vibrio Gazogenes, Shonda Renee Jones

Theses and Dissertations

Vibrio gazogenes, a Gram-negative species of marine bacteria, was capable of transporting 20 nm (diameter) surface-carboxylated, polystyrene, fluorescent FluoSpheres® microspheres (excitation/emission = 505/515) through the outer membrane, which was indicated by a detectable decrease in the fluorescence intensity of the nanoparticles in the culture medium. A mechanism of transport was investigated involving the ATP-binding cassette (ABC) protein transporters that traverse the outer membrane. Inhibition of the ABC transporters did not prevent the entry of the nanoparticles into the cell, suggesting there was an alternate mechanism of transport. The addition of nanoparticles to the culture medium also did not provide any …

Comparing The Geography Of Environmental Justice Guidelines, Fish Consumption Waterbodies, And Land Use/Land Cover In South Carolina, Matthew James Neet

Theses and Dissertations

Environmental justice (EJ) grew out of the Civil Rights movement of the 1960s, as well as grass roots organizations during the 1980s and early 1990s. However, it was not until President William J. Clinton signed Executive Order (EO) 12898 in 1994 that EJ became an official governmental policy. With this directive, federal agencies made EJ part of their daily operations. EO 12898 had two overriding goals, the fair treatment and meaningful involvement of all populations. As part of these goals, minority, low-income, and native populations would be analyzed for any disproportionate and adverse impacts on human or environmental health. Despite …

On The Influence Of Ionic Strength On Radium And Strontium Sorption To Sandy Loam Soils, Brian A. Powell, Todd Miller, Daniel I. Kaplan Apr 2015

On The Influence Of Ionic Strength On Radium And Strontium Sorption To Sandy Loam Soils, Brian A. Powell, Todd Miller, Daniel I. Kaplan

Journal of the South Carolina Academy of Science

Models which can estimate environmental transport of radioactive contaminants in natural and engineered systems are required to 1) deploy effective remediation strategies for contaminated sites, 2) design waste repositories for future waste streams, and 3) ensure protection of human and environmental health in all cases. These models require accurate transport parameters in order to correctly predict how these contaminants will move in the subsurface. This work aimed to determine more accurately the distribution coefficients for radium and strontium sorption to Savannah River Site (SRS) soils. Radium and strontium sorption to the soils was found to be highly dependent upon ionic …
