Financial Risk In A Changing Climate, Mashuk S. Rahman

LSU New Orleans Theses and Dissertations

Essay 1:

Given the missing-not-at-random (MNAR) nature of carbon emissions figures under the voluntary disclosure regulator environment, this research imputes synthetic emissions figures for both disclosing and non-disclosing publicly traded US firms, using an IV approach adapted for sample bias correction. The forward-observing implied cost of equity capital measure is consistently higher for carbon-intensive firms regardless of disclosure decision. This higher cost found in the large swath of high-emitting firms reduces the net present value of green transition investments, thus fueling existing research on the counterproductive natures of capital allocation in efforts to reduce corporate pollution. Contrary to emerging research, …

Socio-Ecological Drivers Of Anthropogenic Marine Debris Effects On Coral Reef Communities In The Florida Keys, Usa, Tokea Payton

All Dissertations

The Florida Keys reef tract has rapidly shifted from a structurally complex, hard coral-dominated reef to a less rugose, soft coral-dominated reef. Persistent anthropogenic stressors facilitate ecological transitions by including recreational and commercial fishing and increased anthropogenic marine debris. These artificial structures are becoming habitats for small marine taxa known as cryptofauna. Cryptofauna are among the most essential yet understudied reef taxa where little is known about their fate considering degrading coral reefs and increasing anthropogenic disturbance. With increased anthropogenic stressors on the marine environment, the SCUBA diving community has initiated extensive marine debris removal efforts to assist in cleaning …

Private Landowner Interest In Prescribed Fire In California: Findings From Workshops In The Sierra Nevada, Kate M. Wilkin, Amanda M. Stasiewicz, Susan D. Kocher

Faculty Research, Scholarly, and Creative Activity

Background: Globally, prescribed fire political interest and practice has been rekindled following recent devastating wildfire seasons. This phenomenon was especially acute in areas with dual wildfire and forest health crises, like California. Previous research has investigated prescribed fire on public lands or on private lands in other regions, but little is known about prescribed fire practice or interest on private lands in California. Therefore, we sought to understand private land managers’ perceptions of prescribed fire compared to other land management techniques, treatment pathways, motivations, and barriers to complete these treatments in California. Results: Before workshops on prescribed fire for private …

Effects Of Metoprolol And Propranolol Beta-Blockers Mixture On Morphological And Physiological Responses In The American Oyster, Andrew Salinas

Theses and Dissertations

Beta-blockers are extensively used to treat human cardiovascular conditions yet pose significant risks to non-target aquatic organisms. This study aimed to investigate the effects of short-term exposure (one week) to a beta-blocker’s mixture (low-dose: 50 ng/L propranolol and 250 ng/L metoprolol, and high-dose: 250 ng/L propranolol and 650 ng/L metoprolol) in the American oysters. Histopathological assessments revealed structural damage to gills, connective tissues, and digestive glands in both low- and high-dose treatment groups. Additionally, glucose concentration and pH of the extrapallial fluid significantly declined in the high-dose treatment group. Hemocyte density within connective tissues increased proportionally with dosage. The beta-blocker …

Assessing Khumbu Region Glaciers Mass Balance Change Using Geospatial Techniques From 2012 To 2024, Yashvi Jagatbhai Shah

Electronic Theses, Projects, and Dissertations

The glaciers in the Hindu Kush Himalaya are critical for sustaining the water supply of South Asia's major rivers, upon which over 230 million people, both in the mountainous regions and lowland areas, depend. Climate change is driving rapid glaciers melt near the summit of Mount Everest, located at an elevation of approximately 7,906 meters (25,938 feet). This has resulted in glacier thinning occurring up to 80 times faster than the original ice formation. However, due to their disposition in a complex topographic setting and inaccessible terrain, continuous glacier observations pose significant challenges.

This study evaluated the mass balance of …

Taking an integrated approach combining Discourse Analysis and Document Analysis, this research aims at elucidating the challenges and the potential opportunities of data and information exchange on the Helmand River, a drought-stricken river basin shared between upstream Afghanistan and downstream Iran. Drawing on the Theory of Planned Behavior (TPB), we offer nuanced perspectives on the data exchange model developed by Wehn. We argue that there are other underlying and essential elements that hinder the meaningful engagement of the riparian nations …

The Role Of Christianity In Shaping Agrarian Policies And Environmental Interactions: A Comparative Analysis Of The Uk And The Netherlands, Grace N. Brimble

University Honors Theses

This thesis explores the enduring influence of Protestant Christianity on agrarian practices and environmental policies in the UK and the Netherlands, focusing on how historical religious values shape modern ecological and political landscapes. Despite increasing secularism, Protestant ethics--emphasising stewardship, diligence, and moral responsibility--persist culturally, influencing debates on sustainability, rural identity, and land use. Using case studies such as nitrogen policy protests in the Netherlands and post-Brexit agricultural transitions in the UK, this analysis highlights the symbolic role of Christian values in framing resistance and adaptation to contemporary challenges. The research combines discourse analysis and ethnographic perspectives to uncover the interplay …

Emerging Agency In Border Communities During Pandemics, William Ordeman

All Dissertations

“Emerging Agency in Border Communities During Pandemics” uncovers the complex natural and social histories of two Texas border counties, El Paso and Hidalgo, to explain how these counties became highly susceptible to the COVID-19 outbreak in 2020. This work argues that humans engaging with natural resources throughout history created a rhetoric of exploitation and social hierarchy along the Texas/Mexico border. Rhetoric from Spanish and Anglo colonists coupled with environmental phenomena across time displaced Latinx/e bodies living in these counties into precarious communities called colonias, and the presence of these colonias made each county highly susceptible to disease outbreak. I …

Higher Abundance Of Disturbance-Favoured Trees And Shrubs In European Temperate Woodlands Prior To The Late-Quaternary Extinction Of Megafauna, Elena A. Pearce, Florence Mazier, Ralph Fyfe, Charles W. Davison, Signe Normand, Maria Antonia Serge, Paolo Scussolini, Jens Christian Svenning

School of Geography, Earth and Environmental Sciences

Large herbivorous mammals strongly influence vegetation structure by creating and maintaining open areas and causing disturbance within closed woody habitats. The herbivores alive today in Europe are only a small remnant of the large species that existed in high diversity and abundance before modern humans. The extinction of so many large herbivores during the last 50,000 years, and the loss of megaherbivores (body weight ≥1000 kg) from most of the continent before the Pleistocene–Holocene transition, is likely to have had cascading effects on vegetation structure and composition. To evaluate these effects within the European temperate forest biome, we examine the …

Spatial Gap-Filling Of Himawari-8 Hourly Aod Products Using Machine Learning With Model-Based Aod And Meteorological Data: A Focus On The Korean Peninsula, Youjeong Youn, Seoyeon Kim, Seung Hee Kim, Yangwon Lee

Institute for ECHO Articles and Research

Given the complex spatiotemporal variability of aerosols, high-frequency satellite observations are essential for accurately mapping their distribution. However, optical remote sensing encounters difficulties in detecting Aerosol Optical Depth (AOD) over cloud-covered regions, creating data gaps that limit comprehensive environmental analysis. This study introduces a spatial gap-filling method for Himawari-8/Advanced Himawari Imager (AHI) hourly AOD data, using a Random Forest (RF) model that integrates meteorological variables and model-based AOD data. Developed and validated over South Korea from 1 January to 31 December 2019, the model effectively improved data coverage from 6% to 100%. The approach demonstrated high performance in blind tests, …

Assessment And Prioritization Of Contaminants Of Concern Along Florida's Coral Reef, Ellen Regina E. Skelton

All HCAS Student Capstones, Theses, and Dissertations

Florida’s Coral Reef (FCR) is the third largest barrier reef in the world and faces significant stress from localized land, water, and air-based sources of pollution. Numerous chemical contaminants have been found in waters surrounding reefs and within corals, including pesticides, hydrocarbons, personal care products, pharmaceuticals, and trace metals. However, for most current and emergent environmental contaminants, little to no consistent information exists regarding environmental concentrations or toxicological effects on corals. Assessment of the levels of contaminants in coral reef environments is needed to conduct risk assessments to guide management, restoration, and recovery strategies, and the coral reef resource management …

“It’S Essential We Learn How To Grow For Ourselves”: The Legacies Of Black Gardening In Racialized Food Systems., Funmi Odumosu

USF Tampa Graduate Theses and Dissertations

In this thesis, I aim to investigate the impact of food racism on Black communities, with a specific focus on the importance of gardening in combatting food apartheid and fostering holistic connections to nature and community in school-aged children. Inequitable access to major retail supermarkets and unequal distribution of healthy food options are intentionally occurring patterns in the food spaces of predominately Black communities. These food system inequities exacerbate a lack of consumption and potential consequences on the health and well-being of children of color particularly during critical physical and cognitive developmental periods.

Many solutions to these inequities entail implementing …
