What In The Fukushima Should We Do? Analyzing The Costs Of The Fukushima Daiichi Disaster And Japan’S Reactions, Sara Deal, Mary Blair Dellinger

Caravel Undergraduate Research Journal

The Fukushima Daiichi nuclear disaster, which resulted from the Tōhoku earthquake and subsequent tsunami on 11 March 2011, has caused much debate about the future of the nuclear power industry.  Japan has shut down all of its 54 nuclear reactors and increased power production through fossil fuel plants to make up the difference (Foster 2012).  This paper analyzes Japan’s decision to shut down its nuclear reactors and investigates the environmental, economic, and health costs of this decision. Nuclear power is compared with other forms of power in regards to life cycle cost, land use, CO₂ emissions, and deaths on …

Riparian Ecosystem Condition And Impaired Floodplain Assessment In The Congaree River Watershed, South Carolina, Olusola-Ige O. Adetoro, Cuizhen Wang, Ayobami T. Salami, Olusegun O. Awotoye

Faculty Publications

Floodplain riparian ecological zones (FREZs) are transitional environments that facilitate interactions among hydrological, geomorphological, and environmental processes within aquatic and terrestrial systems. In the context of climate change, urban growth, and increased hydrologic modifications, these systems are experiencing accelerated degradation. This study employed a multi-criteria Riparian Condition Assessment (RCA) framework that combined the Riparian Condition Assessment Tool (RCAT) and a fuzzy inference system (FIS) to evaluate riparian corridor health in the Congaree River watershed, South Carolina, USA. Using 30 m LANDFIRE land-cover data, hydrologic segmentation (at 500 m reach scale), and transport infrastructure overlays, we quantified riparian vegetation deviation, land-use …

Artemisinin partial resistance, driven by Plasmodium falciparum K13 mutations, threatens malaria control. Zanzibar is vulnerable to artemisinin partial resistance spread but lacks recent molecular surveillance. We sequenced samples in Zanzibar and mainland Tanzania collected from 2022 to 2024. K13 mutations were found in 2 of 1440 participants (P441L, A675V) in Zanzibar and 6 of 3762 (R561H, P441L) in mainland Tanzania. Based on whole genome sequencing data, K13 mutations appear to be of African origin with regional spread. Frequent parasite importation appears to maintain partner drug mutation frequencies similar to the mainland, where artemether-lumefantrine selects for mutations favoring artesunate-amodiaquine sensitivity. Ongoing …

Understanding The Epidemiology Of Malaria In Zanzibar Through Molecular And Serological Analysis Of Samples Collected During Reactive Case Detection, Vanrun Goel, Wahida Hassan, Caroline Murphy, Barbara B. Choloi, Mohamed Ali, Shija J. Shija, Jeffrey A. Bailey, Anders Björkman, Billey E. Ngasala, Eric Rogier, Jonathan J. Juliano, Jessica T. Lin

Faculty Publications

Background

The Zanzibar archipelago has been a pre-elimination region for malaria thanks to rigorous control interventions, but recent surges in malaria cases have been observed. The contribution of non-falciparum species to the current malaria situation is unknown.

Method

This study investigates the epidemiology of falciparum and non-falciparum malaria species in Zanzibar. Leveraging plasma extracted from dried blood spots (DBS) collected during reactive case detection (RCD) activities across Unguja island from May 2022 to January 2023, we measured immunoglobulin G (IgG) responses to Plasmodium MSP1-19kD antigens using a multiplex bead-based immunoassay. Additionally, active infections were detected using species-specific real-time PCR.

Faculty Publications

Background

Malaria is a major public health problem, with over half of the world’s population, primarily in sub-Saharan Africa, at risk. Climate change is already affecting the prevalence of malaria, in part by altering the distribution and density of mosquito vectors. This study assessed the relationship between climate variables and mosquito species distribution on malaria prevalence in Kenya from January 2019 to June 2021.

Methods

Data from 23 Kenyan counties were analyzed using mixed-effect regression, spatial analysis, correlation analysis, and the Least Absolute Shrinkage and Selection Operator (LASSO) to select variables.

Results

Malaria prevalence was highest in the Lake Endemic …

Grandmothers Of Invention: A Commentary On Fifty Years Of Hazards And Disasters Research And Practice In The United States, Susan L. Cutter, Kathleen Tierney

Faculty Publications

This commentary highlights the role of “grandmothers of invention”: women in the United States who were the first to enter the field of hazards and disasters as core researchers and who played key roles in advancing the science and practice of hazards/disasters research since 1975. We examine the evolution and transformation of the field from the perspective of the women who were initially entering a male-dominated field. The innovations in theory, concepts, tools, topics, and mentoring the next generation of scholars and practitioners are highlighted. Notably, emphasis on these women's singular and collective influence on practice and policy highlights the …

Toward A Feminist Geo-Legal Reading: Us Country-Of-Origin Information In Asylum Adjudication, Malene H. Jacobsen, Austin Crane, Elise Dosch

Faculty Publications

In this article, we offer what we call ‘a feminist geo-legal reading’ of documents used in spaces and practices of law. Legal cases and decisions are often based on different legal and non-legal documents, including laws, explanatory memorandums, testimonies, medical reports, and so forth. In contemporary asylum adjudication, country-of-origin information reports (COIs) have become a crucial source of authoritative evidence as asylum officers and immigration judges use these reports in their determination of a person's need for and right to protection. However, there is no straight line from COIs' substance to the prevailing authority that they command within asylum adjudication. …

Senior Theses

This study examines the role of Soda City Market in the economic and social revitalization of Columbia, South Carolina’s Main Street district. Since relocating downtown in 2012, the market has evolved from a small farmers market into a major cultural and entrepreneurial hub attracting more than 300,000 visitors annually. To evaluate its impact, the study integrates two primary methods: a vendor survey capturing business characteristics and an IMPLAN input–output model estimating the market’s economic effects within Richland County. Survey results from 25 vendors reveal a diverse and culturally representative business community in which Soda City serves as both an incubator …

Clusters In The Storm: Regional Economic Specialization Before And After Hurricane Harvey, Gwyneth King Waddington

Theses and Dissertations

In recent years, large-scale disaster events have dominated headlines. As the world faces an increasing number of such disasters, it is crucial to understand their impacts beyond immediate monetary losses. Disasters not only directly impact individuals and businesses but may also reshape the spatial patterns of the regional economy. Through a case study of Hurricane Harvey in Texas and Louisiana, this study examines how disaster events influence regional economic specialization patterns and contribute to uneven impacts across economic supersectors and geographies. Expanding on previous methodologies, this study incorporates temporal analysis tools to identify and investigate case studies of economic change. …

Relative Hazard Losses Along The Atlantic And Gulf Coasts, Erin Kemp

Theses and Dissertations

Coastal areas face a variety of natural hazards, many of which are increasing in frequency or severity due to climate change. Continued coastal development emphasizes the need for a better understanding of the impact of these hazards on coastal communities. This study aims to improve this understanding by investigating temporal, spatial, and causal patterns in county-level relative losses (RL) from hazards along the Atlantic and Gulf Coasts from 2001 to 2021. Three research questions are addressed: 1) Are relative losses increasing over time in coastal counties? 2) Where are the highest relative losses among coastal counties? and 3) Which hazards …

Reluctant Transitions: Place And Post-Extraction Politics In Southeastern Ohio, Jenna Lynn Haver

Theses and Dissertations

Based on a summer of ethnographic research in a subsection of Appalachian Ohio colloquially referred to as “The Valley,” this research challenges three narratives of this place that formulate a harmful Appalachian imaginary. The first narrative of industrycontrolled coal heritage is complicated by the way local people negotiate control over their own stories of coal and its existence outside of industry domain. The second narrative characterizes this as a space of extraction which is in tension with different social relations to varying types of energy – especially the discontinuity of the coal to fracking shift. The third narrative centers of …

Combining Remote Sensing And Field Sampling To Assess Microphytobenthos Distribution In The North Inlet Estuary, South Carolina, Joseph Carmine Mcguinn

Theses and Dissertations

The study of microphytobenthos (MPB) distributions in mudflat ecosystems is critical for understanding coastal ecosystem health and resilience. This research integrates high-resolution multispectral imagery and elevation data to predict chlorophyll-a concentrations in mudflats within the North Inlet estuary, South Carolina. Using statistical analyses, MSAVI was identified as the most effective spectral index for chlorophyll-a prediction, and a regression model was generated for this index, finding significant correlation with elevation. Temporal and spatial patterns of chlorophyll-a distributions were explored through predictive rasters, revealing significant relationships between MPB abundance and microtopography. These findings demonstrate the value of remote sensing for …

Between Florida And The World: Young People And The Politics Of Citizenship, Jessica Flach

Theses and Dissertations

This thesis critically examines how American high school students experience and make sense of global citizenship within the context of a commercial educational tour. Drawing on a case study of students from a Title I public high school in Florida, the research interrogates the narratives of civic transformation promoted by educational travel companies and explores how these narratives intersect with students’ lived realities. Combining ethnographic methods, interviews, and critical discourse analysis, the study reveals that global citizenship is not meaningfully realized through such travel experiences; rather, it is fragmented, depoliticized, and often disconnected from the civic education students receive in …

An International Perspective On Geography Curricula: Paving A Way Forward For Geographical Thinking, Tomáš Bendl, Hilde Storrøsæter, Lene Møller Madsen, David Trokšiar, Raphaële De La Martinière, Shanshan Liu, Sizakele Serame, Jerry T. Mitchell, Péter Bagoly-Simó, Yushan Duan, Gillian Kidman

Faculty Publications

Geographical thinking is a cornerstone of modern geography education. Despite its universal value, no large-scale international study has systematically examined its integration into diverse curricular documents. This study investigates how geographical thinking is embedded in the curricula of nine countries, focusing on content and procedural dimensions. Using a structured analytical framework, the research reveals significant patterns and gaps, particularly the underrepresentation of place as a central concept, the lack of explicit focus on geographical thinking, and the limited emphasis on its procedural dimension. The findings emphasise the need for stronger interconnections between these dimensions to promote a more comprehensive approach …

Six Paths Of Global China: A Genealogy Of A Contested Geographical Imaginary, Jessica Dicarlo, Meredith J. Deboom

Faculty Publications

‘Global China’ has emerged as a shorthand for China's relationship to the global, but its axiomatic uses disguise considerable complexity. This article troubles self-evident uses and tidy categorizations of Global China by approaching it as an emergent, pluralistic geographical imaginary warranting critical analysis. Employing a genealogical approach that privileges indeterminacy and inconsistency over linearity and singularity, we draw on wide-ranging sources to reveal the contested, contextual, and contradictory uses of Global China in the contemporary moment. Our analysis identifies six ‘paths’ of Global China: Other, Integration, Bridge, Status, Threat, and Alternative. Each path facilitates distinct yet interlinked claims about …

The Next Four Years: Geographical Reflections On The Second Trump Administration, Caroline R. Nagel, Peter Hopkins

Faculty Publications

In this introductory essay, we reflect on the significance of the re-election of Donald Trump to the presidency in the United States, and we provide some context for interpreting Trump's second term. Two of Trump's early policy moves—the release of billions of gallons of water from reservoirs in California and the granting of refugee status to Afrikaners—portend four years of politics based on alternative facts, conspiracy theories, and racial grievances. Trump's political agenda has received a significant boost from Silicon Valley billionaires, who are keen to eliminate regulatory bureaucracy. Paradoxically, while allied with high-tech futurists, Trump's policies hearken to an …

Stomatal Distribution And Post-Fire Recovery: Intra-And Interspecific Variation In Plants Of The Pyrogenic Florida Scrub, Genevieve Triplett, Aaron S. David

Faculty Publications

Premise

Amphistomy, the presence of stomata on both leaf surfaces, can increase photosynthesis yet is uncommon across vascular plants. The relative infrequency of amphistomy is often attributed to high costs, such as transpirational water loss. The Florida scrub—a hot, dry, shrub-dominated habitat—historically has experienced frequent fire, yet decades of anthropogenic suppression coupled with the reintroduction of prescribed burns has led to varied fire regimes. In this study, we investigated the links between amphistomy and fire with regard to the presence of the trait across species in this pyrogenic habitat and within-species variation before and after experimental fire and across a …

Linking Geographic Distribution And Niche Through Estimation Of Niche Density, Tad Dallas, Cleber Ten Caten

Faculty Publications

1. The availability of suitable niche space constrains where species can occur geographically. This tie between niche space and geographic space is crucial when estimating species geographic distributions in a changing climate. However, specific combinations of climatic conditions may be overrepresented in geographic space, highlighting the potential disconnect between climatic niche area and geographic range size.
2. We develop a niche density estimator that accounts for the geographic availability of climatic niche space, relate this to traditional estimates of niche area and explore how these niche estimates are related to species geographic range size.
3. To do this, we use data on over …

Immigration Policy In The Second Trump Administration: Restriction, Removal, And The Limits Of Maga Nativism, Caroline R. Nagel

Faculty Publications

Donald Trump's three presidential campaigns have centred on promises to stop unauthorised immigration, whether by ‘building the wall’ or by enacting the largest mass deportation in American history. To deliver on these promises, Trump has appointed Stephen Miller—an anti-immigration hardliner who was responsible for the first Trump administration's draconian border policies – to a key White House position. Trump is often described as breaking from liberal-democratic norms; but when it comes to immigration policy, he is following a well-worn path by hiring Miller. This brief commentary places the Trump/Miller brand of anti-immigration politics in historical context, showing how anxieties over …

Economic Development On The Ground: Rural Development And The Distribution Economy, John David Rinehart

Theses and Dissertations

This thesis examines the practice of economic development in the South Carolina at the county and regional level. Looking at the Interstate 95 corridor, this research examines economic development organizations in practice, using in-depth interviews with actors operating at different spatial scales. Specifically, I highlight the current ideology of development as it relates to the proliferation of warehousing and distribution in the state. I outline the ideologies of economic development professionals, including their spatial strategies and perceptions of ‘community’ as it relates to economic development goals.

My research demonstrates the extent to which rural areas have been left without the …

Narratives In Motion: The New Era Of Dam Building In East Africa, Andrew Nicholas Selassie Prado-Alipui

Theses and Dissertations

Narratives of energy insecurity, underdevelopment, and resource conflict influence how African hydropower projects are justified within the broader context of climate change and demands for sustainable development. The challenge of meeting energy demands provides the overarching motivation for ambitious large-scale hydropower projects in East Africa, especially in Tanzania and Ethiopia. As development projects, the Julius Nyerere Hydropower Project (JNHPP) and the Grand Ethiopian Renaissance Dam (GERD) can be understood as vehicles of political discourse, framed as the technopolitical solution to questions of national identity that both countries face in the midst of sociopolitical and economic transformation periods. This research shows …

Mapping Fire Susceptibility Of The South Carolina Coastal Plain, Breonna Roden

Theses and Dissertations

Wildfires are a natural hazard that have occurred across the world, throughout time. Regions prone to wildfires have been experiencing changes in their fire regimes. Not only has the fire season length increased, but the fires themselves are increasing in frequency and intensity. Wildfire research has been limited for the state of South Carolina, raising concerns along with global warming and population growth. Global warming is likely to become more extreme, which can lead to droughts becoming more frequent and lasting for longer periods of time. According to the 2020 census, South Carolina was the 10th fastest-growing state, which is …

Racial Contestations Of Space: Rural Preservation And Black Municipal Development In The South Carolina Lowcountry, Sydney Elizabeth Potter Smith

Theses and Dissertations

As newcomers flock to the South Carolina Lowcountry and drive development, the region has generally implemented strategies to preserve what remains of the region’s iconic rural landscapes by restricting new development in places that are designated as “Rural Areas”. These multi-scaler growth management strategies are problematic because they frame rural preservation as benefiting the greater good and prescribe a universal solution to urban sprawl, regardless of the individual needs of rural communities. This naturalizes and perpetuates forms of racial inequality across the landscape. Simultaneously, there are alternative spatial practices that aim to improve the quality of life for rural residents …

Trump And The Us Energy Transition, Conor M. Harrison

Faculty Publications

The US electricity grid has seen a rapid increase in the amount of renewable energy over the last decade, with many renewable advocates viewing the Inflation Reduction Act of 2022 as the catalyst to move the grid towards 100% clean energy. The 2024 elections, however, have significantly muddied the path. In this commentary, I posit what the Trump administration—and related Republican control of both houses of the US Congress—means for the US electricity system. I begin by briefly outlining the contours of federal and state electricity governance, the design of Inflation Reduction Act, the existing drivers of renewable energy growth …

Displaced Decarbonization: Climate Necropolitics And The Contested Spatialities Of Green Hydrogen In Namibia, Meredith J. Deboom

Faculty Publications

Green hydrogen is often presented as a transformative solution to the dual challenges of decarbonization and economic development. This article applies the framework of climate necropolitics to interrogate the contested spatialities underlying such “win-win” narratives. It does so through an extended case study of Hyphen Hydrogen Energy, a $10 billion green hydrogen project planned for Lüderitz, Namibia. A remote town of 20,000 in a country with a $12 billion annual GDP, Lüderitz initially appears to be an unlikely host site for the “industrial fuel of the future.” To explain this outcome, I first illustrate how discordant socio-spatial projects—including European energy …

Explaining Youth Driver Licensing Determinants Using Xgboost And Shap, Kailai Wang, Jonas De Vos, Michael Smart, Sicheng Wang

Faculty Publications

This study explores the factors influencing driver's license acquisition among young individuals and examines its broader implications for mobility, safety, and sustainability. Leveraging nationally representative survey data on Millennials and Generation Z, we apply eXtreme Gradient Boosting (XGBoost) and SHapley Additive Explanations (SHAP) to identify key socioeconomic determinants of teenage driver's license attainment. Our findings reveal consistent predictors across both generations, including the percentage of licensed family members, household income per capita, educational attainment, and public transit ridership. We identify meaningful dose-response relationships, such as the increasing influence of licensed household members beyond a 0.75 threshold and the …

Hedging Energy Transition: Green Hydrogen, Oil, And Low-Carbon Resilience As State Strategy In Namibia, Meredith J. Deboom

Faculty Publications

Policy frameworks increasingly portray energy transition as a mechanism for achieving a range of resilience- related goals, including socio-economic development and energy security. Energy transition is often character ized as a particularly important resilience strategy for lower-income states in the Global South, which face the simultaneous challenges of decarbonization and development. Yet these states, many of which have fossil fuel resources, face distinct constraints and risks in navigating energy transition, including the possibility that promised funding for low-carbon energy projects will never come to fruition or that global decarbonization will be deferred or abandoned completely. This article uses the case …

Suspended Agency And The Habitus Of Waiting In A Migrant Shelter In Tijuana, Liam K. Ogden Iii

Senior Theses

This thesis explores idea of suspended agency and the development of a habitus of waiting within a women and children’s migrant shelter in Tijuana, Mexico. Relying on ten days of participant observation and an interview with a shelter director, I examine the lived experiences of residents, workers, and myself as a researcher navigating humanitarian space. Shelters are designed to be short term spaces, but migrants are often forced into long-term, uncertain stays due to restrictive border policies and structural barriers, resulting in a social stasis defined by boredom, anxiety, and monotony within the shelter. Drawing on Bourdieu’s concept of habitus …

Could It Be Cold War? How Sino-American Tensions Are Unfolding In The South Pacific., Peter R. Caldwell

Senior Theses

This thesis assesses the impacts of geopolitical competition between the United States and China, focusing on the South Pacific as a primary theatre for this great power contest, and investigating the uses of foreign aid by regional powers to effect both the geopolitical alignment and domestic policies of the developing states of the South Pacific. This paper finds that foreign aid to these South Pacific States is geopolitically motivated, and induces greater attention from competing regional powers, furthering the ongoing competition. This paper first provides an overview of the evolving political situation in Kiribati, a Pacific Island Country which has …
