Geography ETDs

This thesis examined the geospatial and temporal grazing patterns of domesticated livestock to model individual-level exposure potential to abandoned uranium mine (AUM) waste in a tribal community in the Southwest United States. Lotek Litetrack Global Positioning System (GPS) collars collected data at 20-minute-intervals for 2 flocks of sheep and goats during the Spring and Summer of 2019. Depending on the flock and individual animals, tracking time ranges from 10 days to four months. This research developed a GIS-based exposure potential framework that built on existing methodologies in time geography, GIS, and exposure mapping. This thesis aims to: 1) classify GPS …

A Fused Radar–Optical Approach For Mapping Wetlands And Deepwaters Of The Mid–Atlantic And Gulf Coast Regions Of The United States, Brian T. Lamb, Maria A. Tzortziou, Kyle C. Mcdonald

Publications and Research

Tidal wetlands are critically important ecosystems that provide ecosystem services including carbon sequestration, storm surge mitigation, water filtration, and wildlife habitat provision while supporting high levels of biodiversity. Despite their importance, monitoring these systems over large scales remains challenging due to difficulties in obtaining extensive up-to-date ground surveys and the need for high spatial and temporal resolution satellite imagery for effective space-borne monitoring. In this study, we developed methodologies to advance the monitoring of tidal marshes and adjacent deepwaters in the Mid-Atlantic and Gulf Coast United States. We combined Sentinel-1 SAR and Landsat 8 optical imagery to classify marshes and …

Mapping Complex Land Use Histories And Urban Renewal Using Ground Penetrating Radar: A Case Study From Fort Stanwix, Tyler Stumpf, Daniel P. Bigman, Dominic J. Day

Anthropology Graduate Research

Fort Stanwix National Monument, located in Rome, NY, is a historic park with a complex use history dating back to the early Colonial period and through the urban expansion and recent economic revitalization of the City of Rome. The goal of this study was to conduct a GPR investigation over an area approximately 1 acre in size to identify buried historic features (particularly buildings) so park management can preserve these resources and develop appropriate educational programming and management plans. The GPR recorded reflection events consistent with our expectations of historic structures. Differences in size, shape, orientation, and depth suggest that …

Creating A Field-Wide Forage Canopy Model Using Uavs And Photogrammetry Processing, Cameron Minch, Joseph S. Dvorak, Joshua J. Jackson, Stuart Tucker Sheffield

Biosystems and Agricultural Engineering Faculty Publications

Alfalfa canopy structure reveals useful information for managing this forage crop, but manual measurements are impractical at field-scale. Photogrammetry processing with images from Unmanned Aerial Vehicles (UAVs) can create a field-wide three-dimensional model of the crop canopy. The goal of this study was to determine the appropriate flight parameters for the UAV that would enable reliable generation of canopy models at all stages of alfalfa growth. Flights were conducted over two separate fields on four different dates using three different flight parameters. This provided a total of 24 flights. The flight parameters considered were the following: 30 m altitude with …

A Quantitative Validation Of Multi-Modal Image Fusion And Segmentation For Object Detection And Tracking, Nicholas Lahaye, Michael J. Garay, Brian D. Bue, Hesham El-Askary, Erik Linstead

Mathematics, Physics, and Computer Science Faculty Articles and Research

In previous works, we have shown the efficacy of using Deep Belief Networks, paired with clustering, to identify distinct classes of objects within remotely sensed data via cluster analysis and qualitative analysis of the output data in comparison with reference data. In this paper, we quantitatively validate the methodology against datasets currently being generated and used within the remote sensing community, as well as show the capabilities and benefits of the data fusion methodologies used. The experiments run take the output of our unsupervised fusion and segmentation methodology and map them to various labeled datasets at different levels of global …

Understanding The Unique Spatial Relations And Power Dynamics Of China’S Urban Villages, Kaitlyn Zhao

Dartmouth Undergraduate Journal of Politics, Economics and World Affairs

China’s recent history as a Communist stronghold-turned-economic-powerhouse has garnered widespread scholarly and popular attention, as its government seeks to marry economic liberalization with one-party rule, propping up the private sector while retaining the preeminence of the CCP (Chinese Communist Party). As its economy continues to grow at astounding rates and the state begins to take a more forward position on the world stage, many have deemed it an impending threat to Western hegemony. Yet focusing on China’s outward positioning obscures the many peculiarities bubbling within it. On the ground, the landscape of the country has been fundamentally transformed within a …

Evacuation Decision Making And The Role Of Social Connections Across Evacuation Statuses During Hurricane Irma, Nathan D. Shull

USF Tampa Graduate Theses and Dissertations

The purpose of this research was to examine the evacuation decision-making process during Hurricane Irma in 2017. Special consideration was given to the role of an individual’s social connections (SCs). Additionally, the dependability, density (i.e., social network size and number of connections), and diversity of SCs were compared between those who: (a) evacuated to a shelter in Pinellas County, (b) evacuated to somewhere outside of the Tampa Bay area, and (c) did not evacuate. Data for evacuees and non-evacuees from Collins et al. (2018) were used to perform this comparison, while the data for shelter evacuees were acquired via a …

Comparing Household And Individual Measures Of Access Through A Food Environment Lens: What Household Food Opportunities Are Missed When Measuring Access To Food Retail At The Individual Level?, Lindsey G. Smith, Michael J. Widener, Bochu Liu, Steven Farber, Leia M. Minaker, Zachary Patterson, Kristian Larsen, Jason Gilliland

Geography & Environment Publications

Geographers and public health researchers have long been interested in social, spatial, and economic factors that drive access and exposure to food retail. A growing body of evidence draws on mobility data to capture locations accessed by individuals beyond the home address. Given that food-related activities are shared by household members and often gendered, taking an individual-level approach might limit researchers’ ability to accurately describe access to food retail. Using data that includes Global Positioning System trajectories of forty-six adults from twenty-one households in Toronto, this study compares access to food retailers at the individual and household levels and evaluates …

Monitoring War Destruction From Space Using Machine Learning, Hannes Mueller, Andre Groeger, Jonathan Hersh, Andrea Matranga, Joan Serrat

Economics Faculty Articles and Research

Satellite imagery is becoming ubiquitous. Research has demonstrated that artificial intelligence applied to satellite imagery holds promise for automated detection of war-related building destruction. While these results are promising, monitoring in real-world applications requires high precision, especially when destruction is sparse and detecting destroyed buildings is equivalent to looking for a needle in a haystack. We demonstrate that exploiting the persistent nature of building destruction can substantially improve the training of automated destruction monitoring. We also propose an additional machine-learning stage that leverages images of surrounding areas and multiple successive images of the same area, which further improves detection significantly. …

A Community Of Fear: Emotion And The Hydro-Social Cycle In East Porterville, Michael Egge

Geography Masters Research Papers

Broader governance challenges driving water insecurity globally are well documented in the literature, however the power-laden relationships and emotions that shape water access at the household and community levels are yet to be fully investigated, especially in the context of water consolidation projects. In this article, we examine the role of emotions in mediating access to water and in the production of resource struggles among marginalized communities existing outside of conventional regulatory frameworks. We bring together two relational approaches – the hydro-social cycle and emotional political ecology – to examine water insecurity and how it manifests in the historically disadvantaged …

Material Encounters: Making Memory Beyond The Mind, Ariel Wills

Masters Theses

Can acts of making carry the memories of our embeddedness within the world? This thesis explores how making things can nurture a sense of kinship that cuts across the organic and inorganic, erasing the distinction between living and dead, material and spiritual. Through handwork such as art-making, sewing, knitting, cooking, woodworking, and beyond, the burden of remembering and of archiving is shared across human and non-human bodies, cultivated through practices of making, and through the materials themselves. By recounting the stories of my family’s experience as Jewish immigrants in the United States, I aim to reveal how their domestic practices …

Contested Landscapes, Disputed Realities: An Investigation Of Socio-Environmental Conflict From Mining In Northern Ecuador: An Honors Thesis, Ian F. Hirons

Student Works

For decades, Ecuador has been one of the preeminent petrostates in South America. However, in response to recent drops in global demand and pricing for oil products, the country has made serious commitments to further develop its mineral resources. By opening a new natural resource sector, Ecuador has firmly cemented itself as a primarily extractivist nation. In the process, the national government has frequently come into conflict with activist and community groups who protest the encroachment of extractive industry. This thesis explores the various dimensions of socio-environmental conflict created by large-scale mining projects in northern Ecuador with specific attention to …

Sacred Music In Colonial Era Hispaniola: The Evangelization Of The Taino People, Tito J. Gutierrez

Student Theses

During the 15th-18th centuries, the major European religious orders; the Franciscans, Dominicans, Jesuits, and Jeronymites, journeyed to the newly colonized American territories in an attempt to convert the multitudes of natives peoples living there. Along with prayer books, crucifixes, and religious images, these missionaries brought sacred European music to American shores in an attempt to attract the native people to the Catholic faith.The use of music as a tool for conversion of native people in places such as Mexico, South America, California, and the South West United States, have been well researched and documented. However, the research of the spiritual …

Responding To Social Disruptions And Urban Complexities In Post-Pandemic Dhaka Using Resilience Framework: Implications For Low-Income Urban Populations, Saleh Ahmed

Global Studies Faculty Publications and Presentations

Social, economic, and spatial inequalities are not unknown in megacities like Dhaka, which have a degree of urbanization that could be termed “hyperurbanization” or “overurbanization.” Currently, Dhaka is the home of almost 18 million people and, prior to COVID-19, the population grew, mostly by the rural-urban migrants, by thousands of people every day. In Bangladesh, various natural hazards, food insecurity, low-investment, and policy priorities in rural areas have played a major role in mass-scale rural-urban migration. COVID-19 has brought a new reality. Despite an initial effort, the state is not in a position to provide food and other resources to …
