Yellowtail Snapper: Human-Ecological Relationships In The South Florida Fishery, Brent Stoffle, Amanda D. Stoltz
Journal of Ecological Anthropology
In 2018 over a period of five months researchers from National Oceanographic and Atmospheric Administration’s (NOAA) Southeast Fisheries Science Center (SEFSC) conducted a study with fishermen and local business owners who participate in the South Florida Yellowtail snapper fishery. Fishermen were asked about changes in their targeting strategies over the last several decades; and they perceive these changes to have altered the health and the biology of the snapper species. The changes are perceived as partially responsible for improving both the overall abundance of Yellowtail and having sped up its the growth and reproductive cycles. This is a case where …

Altered Natural Dyes As Alternatives To Expensive Ruthenium-Complex Sensitizers In Dye-Sensitized Solar Cells, Hunter Sullivan
Theses & ETDs
Solar energy is one of many forms of renewable energy which seeks to replace the use of harmful fossil fuels for the production of energy by humans worldwide. One of the ways to make this more viable is to decrease the production cost of solar technologies, without also decreasing their efficiency. Natural dyes extracted from plants can be used as sensitizers for dye-sensitized solar cells in order to decrease their production cost compared to the commonly used and most efficient ruthenium-complex sensitizer, N719 dye. However, natural dyes have been held back from wide-scale commercial implementation due to the critical trade-off …

Gardening The Gilded Age: Creating The Landscape Of The Future, Jackie L. Perkins
Browse all Theses and Dissertations
The Gilded Age was a time of rapid change in the United States' history. In contrast to the extensive literature regarding wilderness and the founding of environmental organizations during the period, relatively little has been written about the gardens of private residences and the impact these gardens have had on today's environment. These gardens, and the individuals who designed and provided for them, were at the forefront of the introduction of many new and exotic plants to the American landscape. This thesis explores two built environments, North Carolina's Biltmore Estate and the Barker Mansion in Indiana, and how these environments …
Misremembering Risk In The Age Of Hurricanes: The Rhode Island Coast In The 1930s-1950s, Kara M. Schlichting
Misremembering Risk In The Age Of Hurricanes: The Rhode Island Coast In The 1930s-1950s, Kara M. Schlichting
Publications and Research
This paper explores the lost history of New England hurricanes and how the “return” of hurricanes challenged understandings of the environmental vulnerabilities of coastal communities and weather. A series of severe New England hurricanes from 1938-1954 forced Rhode Islanders to reassess coastal vulnerabilities and protection strategies. Before the hurricane of ’38, Rhode Islanders lived with the vulnerability of seasonal erosion and winter storms, but believed their state was, and would remain, safe from hurricanes. In a new era of the shore-at-risk, the Army Corps of Engineers re-wrote the forgotten history of coastal dangers. Dense development along Narragansett Bay and the …

The Air That We Breathe: Neutral Pfas In Indoor And Outdoor Air, Maya Erin Morales-Mcdevitt
Open Access Master's Theses
Neutral, volatile perfluorinated alkyl substance (PFAS) precursors, such as fluorotelomer alcohols (FTOHs), perfluorooctane sulfonamides (FOSAs), and perfluorooctane sulfonamide ethanol (FOSEs) are industrial (by)products that are commonly present in indoor environments, and have been found in urban, industrial, and even rural locations. They have also been detected in remote regions, such as the Arctic, suggesting that these compounds are transported long distances in the. However, measuring volatile and neutral PFAS in air and water has proven to be challenging. Therefore, in order to accurately measure these compounds in different indoor and outdoor environments from urban, rural, industrial and remote regions, we …

Change In Rainfall Patterns In The Hilly Region Of Uttarakhand Due To The Impact Of Climate Change, Dilip Kumar, Rajib K. Bhattacharjya
Applied Environmental Research
Uttarakhand, a Himalayan state of India, may experience an increase in temperature of 1.4°C to 5.8°C by 2100 due to global warming. The rise in temperature may melt the glaciers of the state and may have some significant impact on the rainfall. In this study, we have quantified the changes in the rainfall of the state. Also, an attempt has been made to evaluate the impact of climate change on rainfall. The future rainfall can be estimated by using a global circulation model (GCM). However, due to the very coarse spatial resolution of the different GCM, we cannot use them …

Environmental Degradation-Education Nexus In Malaysia, Wong Sing Yun
Applied Environmental Research
This study aims to examine the role of education on CO2 emissions in Malaysia from 1974 to 2014. The unit root tests indicated that the variables were integrated in the same order. As such, the Johansen Co-integration Approach can be employed in this empirical analysis to analyze the impacts of the selected variables. The long-run estimation revealed that economic growth (GDP) and energy consumption (ENERGY) has a negative effect on CO2 emissions. Meanwhile, secondary school education (EDU) demonstrated a significant positive relationship with environmental degradation in the long-run. This can be inferred that secondary school education has a negative effect …

Divide And Slaughter: Bridging The Gap Between Animal Rights And Racial Justice Through An Analysis Of The Link Between Slaughterhouses And Domestic Violence, Kailey Mcneal
Pitzer Senior Theses
This thesis concerns the injustices present in industrial animal agriculture in the United States, domestic violence, and their disproportionate impact on marginalized communities. Despite the work of social movements centered around domestic violence and the slaughterhouse, the state of both continues to worsen, particularly for communities of color. My research seeks to uncover what factors preclude the efficacy of these movements. A qualitative analysis of the labor advocacy and animal rights movements in the slaughterhouse and the domestic violence advocacy movement suggests that the current disparate framings of these injustices and a lack of attention to race contribute to the …
