The Geography Of Race: A Spatial Analysis Of Free People Of Color In The City Of Charleston (1790-1861), Alexandra Ullman

All Theses

In Charleston, South Carolina, for all but one year from 1790 to 1860, the enslaved and free Black population outnumbered that of the white. Through manumission, the process of an enslaved person gaining their freedom, the free Black population grew substantially and reached a peak in South Carolina during the nineteenth century. This large community of free people of color (FPOC), shifted the social climate by upsetting the balance of white power, thus increasing racial conflict, tension, and legislation that aimed to control the movement of FPOC.

Despite FPOC comprising a significant portion of the total population of Charleston, there …

Machine-Learning Landslide Susceptibility And Runout Modeling In The Nolichucky River Gorge After Hurricane Helene, Grace Braver

Electronic Theses and Dissertations

Extreme rainfall from Hurricane Helene (September 2024) triggered widespread landslides across the southern Appalachian region, highlighting the need for rapid landslide susceptibility assessments that capture both landslide initiation and downstream runout. Traditional susceptibility models often focus solely on initiation zones, limiting their ability to identify which slopes will generate destructive landslides or where material will travel. This study addresses that gap by (1) integrating Geographic Information System (GIS)-based machine learning susceptibility modeling using ArcGIS Pro: Maximum Entropy (MaxEnt) and Random Forest-Based and Boosted Classification and Regression (FBBC) and (2) the U.S. Geological Survey (USGS) Grfin (Growth, Flow, and Inundation) runout …

Conventional Vs. Regenerative Apple Orchard Management In Michigan, Anthony Poynter

Masters Theses

This study compares the variables and outcomes of a conventional apple orchard and a regenerative apple orchard production system in Kent County, Michigan. The premise is that conventional agriculture relies on high-input systems characterized by synthetic fertilizers, pesticides, herbicides, and fungicides, while regenerative agriculture focuses on long-term soil health, biodiversity, and ecological processes. These differences are important as soil degradation, nutrient loss, and environmental impacts are becoming too significant to ignore. Most research on alternative ways to farm, such as regenerative practices, is focused on annual crops, while perennial orchard systems, especially in the Great Lakes region, have gained limited …

Increasing Accuracy Of Mapping Local Climatic Zones Using Building Height And Spectral Unmixing, Ian Douglas Stauffer

Masters Theses

Local climatic zone (LCZ) classifications are traditionally done using reflectance, population data, and often climatic data. The goal of this research is to utilize Google’s new “Open Buildings Temporal v1” building data set as well as “spectral unmixing”. With the objective of testing, assessing, and implementing this data set into the workflow of LCZ mapping. After testing the quality of the data against a validated LiDAR data set from the same year as a given “Open Buildings Temporal v1” band, I implemented it into the Random Forest machine learning process.

Public Pool Usage As Adaptation Against Urban Heat, Stefan Borsky, Eric Fesselmeyer

Research Collection College of Integrative Studies

This paper examines the relationship between urban heat and outdoor public pool usage. Using attendance data from all 53 outdoor public pools in New York City, we analyze nonlinear effects of heat on pool usage across socioeconomic contexts. Pool attendance rises sharply with heat, especially in low-income neighborhoods where alternative coping options are likely limited. We also find that public pools reduce heat-related emergency medical service calls. Our findings highlight the need for equitable investment in blue infrastructure to enhance urban climate resilience and demonstrate how this type of adaptive infrastructure can play a critical role in managing urban heat.

Passive Microwave Remote Sensing Of Flash Drought Impacts On Vegetation, Quinton R. Deppert

School of Natural Resources: Dissertations, Theses, and Student Research

In 2002, Dr. Mark Svoboda characterized a new form of drought known as flash drought. Flash drought was defined as a rapid decline in vegetation health caused by severe heat and drought. In recent years, attempts to quantify the impacts of flash drought via precipitation, soil moisture, evapotranspiration, and temperature indicators have proliferated. What has rarely been quantified is what the rapid decline in vegetation health amid flash drought looks like through remote sensing. This is because vegetation health indices like the Normalized Difference Vegetation Index (NDVI) are derived from the visible and infrared regions of the electromagnetic spectrum and …

On The Trail, In The Towns: Visitor Use And Community Perspectives Along Montana’S Continental Divide Trail, Ava Worbets, Kika Bradford, Melissa Weddell

Institute for Tourism and Recreation Research Publications

As outdoor recreation participation has steadily increased nationwide over the past decade, reaching record levels in 2024 amid long‑term growth trends (OIA, 2025), the Continental Divide Trail (CDT) is drawing rising numbers of hikers traveling through Montana’s gateway communities.

Graduate Theses and Dissertations

The increased usage of unmanned aircraft systems (UAS) for various applications has broadened access to high-resolution aerial imaging, a field with deep roots in geography, remote sensing, and geospatial science. Radiometric correction in satellite imagery has its origins in the early decades of Earth observation, with foundational work beginning alongside the launch of the first multispectral satellites and evolving through decades of research into atmospheric correction, sensor calibration, and reflectance modelling. As UAS adoption grows, research into atmospheric attenuation effects on UAS imagery becomes necessary. Empirical line calibration converts digital number values to surface reflectance and is used here to …

Using Satellite-Observed Geospatial Inundation Data To Identify The Impacts Of Floods On Firm-Level Performance: The Case Of China During 2000–2009, Pao-Li Chang, Fan Zheng

Research Collection School Of Economics

This paper compiles high-resolution geospatial inundation areas of China for the period 2000–2009 based on satellite imagery repositories filtered by the Global Flood Database (GFD). In parallel, we geocode a comprehensive firm-level dataset of China and combine these two sets of geospatial data to identify the set of inundated firms in each year of flood events, as well as the distances of all non-inundated firms from the inundated areas. Given the high-resolution inundation data, we adopt a generalized dynamic-panel specification to estimate dynamic and spatial spillover effects of floods on firm-level production activities (including outputs, capital and labor inputs, and …

Spiritual Gentrification Amid The Rise Of Platform Urbanism: "Wanghong Temples" And Emerging Buddhist Cultural Economies In Tianzhu Road, Hangzhou, China, Han Zhang, Junxi Qian, Lily Kong

Research Collection School of Social Sciences

This study scrutinizes how the Tianzhu Road in the Lingyin Community - a peri-urban area in Hangzhou ringed by a cluster of temples that constitutes a distinct spiritual enclave - has been reworked through a two-phase gentrification process driven by the spiritual aesthetics and platform logics. Drawing on a two-month ethnography and media content analysis, this study conceptualizes spiritual gentrification as a spiritual aesthetics and culture-oriented recalibration of urban space in which spiritual elements operate as symbolic capital, attracting culturally motivated entrepreneurs and aligning the spiritual atmosphere with slow-life values as an alternative to urban modernity. In particular, platform urbanism …

Honors Projects

Human activity is already triggering damaging environmental tipping points (Lenton, 2020), emphasizing the need for sustainability in all aspects of development. Institutes of Higher Education (IHEs) have the power and responsibility to contribute to a more sustainable world (Parr et al., 2022). Bowling Green State University (BGSU) in Ohio, United States, and the Paris Lodron University of Salzburg (PLUS) in Salzburg, Austria are two IHEs with multifaceted sustainability programs. While living and studying at BGSU and PLUS, I used autoethnography, a personal narrative approach, combined with public sustainability information to compare the sustainability initiatives at each university, and determine what …

How Far Is Too Far? Travel Planning Burdens In Autism Families, Risae Carlson, Daniel Olsen, Ruth Kerry

FHSS Mentored Research Conference

This study examines how the burden of planning and risk management influences travel distance and destination choice among families with a child on the autism spectrum. Survey data from Utah-based parents indicate that higher planning burden is associated with a preference for familiar, closer-to-home destinations and shorter travel distances. Despite these constraints, families report that travel remains highly valuable for bonding, fostering a sense of normalcy, and supporting developmental growth.

From Crown To Communism To Crown: Reconstruction In Budapest's Castle District Reveals How Heritage Is Selectively Rebuilt To Shape National Identity, Risae Carlson, Daniel Olsen

FHSS Mentored Research Conference

This project examines how reconstruction in Budapest’s Buda Castle District shapes perceptions of authenticity and historical memory. Following World War II destruction and socialist rebuilding, post-1989 reconstruction has emphasized a return to imperial-era aesthetics. Using visual and historical analysis, this study shows how different political periods have reshaped the same space to reflect shifting cultural priorities. While the district appears historically cohesive, many structures are reconstructed rather than preserved. This creates tension with UNESCO’s standards of authenticity and integrity. The findings suggest that reconstruction does not simply restore the past but actively reshapes it by prioritizing certain narratives while downplaying …

Impact Of Living Shorelines On Coastal Morphology And Sedimentology, Sydney Garber

Electronic Theses and Dissertations

Living shorelines, or nature-based solutions, have emerged as a preferred approach to coastal restoration, but have not been well studied or monitored postimplementation. This project evaluated the efficacy of living shorelines in protecting and stabilizing coastal morphology in Palm Beach County’s Lake Worth Lagoon. The study assessed surface and subsurface sedimentology, short-term water-level variability, and morphological change at two living shoreline areas of Jewell Steinhardt Cove and Snook Islands Natural Area. Each shoreline area has different breakwater designs aimed at stabilizing the shoreline with recruitment of oysters and mangroves in the Lake Worth Lagoon. Overall, seasonal morphology and sediment data …

Where's Our Water? Invasive Saltcedar's Thirsty Trek Across The Shoreline Of Lake Mead, Mia R. Morgan, Joseph Penrod, Ruth Kerry

FHSS Mentored Research Conference

The prolonged megadrought in Southern Nevada has exposed thousands of acres of former lakebed at Lake Mead, creating an expanding frontier for the invasive shrub Tamarix ramosissima, commonly known as saltcedar. This hardy, non-native species rapidly colonizes the receding shoreline, siphoning up to 200 gallons of water per plant daily and outcompeting native vegetation. Utilizing high-resolution satellite imagery from 2020 and 2025, this research found that saltcedar coverage within a 5 km radius of the lake increased by approximately 76.7%.

Analysis of the spatial data indicates that while the total area of infestation has exploded, the average distance of …

Finding Belonging In A Religious Dominant Society: Religion Among African Migrants In Türkiye, Garrett L. Wride, Stacey A. Shaw

FHSS Mentored Research Conference

As global migration increases each year, so does the need to understand the crossroads between inclusion, wellbeing, and religion. The experience of African migrants living in Türkiye presents itself as a unique case to study migrant wellbeing. Using quantitative and qualitative analysis, this study shows that African migrants in Türkiye belonging to the religious minority have lower scores of wellbeing and social support.

Organizing To Engage: A Framework For Conflict Strategy, Paul Mason Carpenter

Dissertations

Conflict strategy can be exceedingly complex. While many of the basics are simple, even the simple can be highly complicated to execute. The Schlieffen Plan in World War I appeared straight forward, but execution was a great deal more complex. It failed and the result was years of trench warfare.  In addition, leaders entering conflict may not fully appreciate the full context, its effect, and the need for a long term result--a better state of peace.

Strategy and tactics may be challenging to transform as an engagement evolves. In addition, strategists must often commit to courses of action within very …
