Clearing The Air: Tracking Spatial And Temporal Pm2.5 Variability Along A Biking Transect In Chicago, Beau R. Rass
DePaul Discoveries
Fine particulate matter (PM₂.₅) poses significant risks to human health and disproportionately affects marginalized communities in urban environments (World Health Organization [WHO], 2021; Tessum et al., 2021). Using low-cost mobile sensors, this study explored spatiotemporal PM₂.₅ concentration patterns along a north–south transect of Halsted Street in Chicago. A 2B Technologies Portable Aerosol Monitor (PAM) mounted on a bicycle was used to continuously record PM₂.₅ concentrations with associated GPS coordinates at approximately two-second intervals during 16 sampling events between 08-12-2025 and 10-05-2025. PM₂.₅ concentrations did not differ significantly among the South Side, West Loop, and North Side regions, contrary to the …
Scraping The Earth: Testing Ndvi As An Indicator Of Military Ground Maneuver Within The Israeli Invasion Of The Gaza Strip, Thomas A. Bergeron
Scraping The Earth: Testing Ndvi As An Indicator Of Military Ground Maneuver Within The Israeli Invasion Of The Gaza Strip, Thomas A. Bergeron
LSU Master's Theses
The advancement of open-source (OSINT) and geospatial intelligence (GEOINT) has allowed independent researchers to study human conflict in new ways, with tools that were previously reserved only for state intelligence agencies. In order to advance methodologies, researchers must continue to evaluate new tools to study war. Valued for its accessibility and moderate spatial resolution, the Normalized Difference Vegetation Index (NDVI) is one such tool that has not been widely systematically tested for its use in an open-source GEOINT investigation of modern conflict. This study tests NDVI as an indicator of military maneuver by leveraging a mixed-method approach against open-source kinetic …
Exploring Tourism Business Voices In Navigating Pandemic Crisis And Resilience-Building, Godwin Adiel A. Lema
Exploring Tourism Business Voices In Navigating Pandemic Crisis And Resilience-Building, Godwin Adiel A. Lema
Tanzanian Economic Review
COVID-19 challenged mobility, redefining crisis navigation and resilience. A modified Challenge Metamorphosis Model (CMM) is proposed to understand crisis navigating process in tourism business resilience-building. A pragmatic mixed-method design, involving 158 tourism-business respondents, multiple regions, interviews, and observation during June–November 2020, was applied. Impacts, challenges, opportunities, varied business responses and outcomes were mirrored. Immediate reactive closure and booking cancellation responses were distinguished from proactive adaptive business continuity measures with low visitors, postponement, few bookings and negotiable employment flexibility. Health, safety, and culturally embedded coping practices and their reinvention aided crisis navigation. Medium-term crisis navigating strategies were differentiated from long-term resilience-building …
Destination “Burning River”: Restoration And Placemaking In A Rust Belt City, Mia Compton-Engle
Destination “Burning River”: Restoration And Placemaking In A Rust Belt City, Mia Compton-Engle
Geography Undergraduate Senior Theses
In 1969, the Cuyahoga River in Cleveland, Ohio caught fire from industrial pollution. Media narratives reframed the river fire as a symbol of environmental degradation, discursively transforming the Cuyahoga River from a place of industrial sacrifice to a place deserving ecological stewardship. Consequently, the river fire catalyzed the modern American environmental movement and local urban river restoration, materially transforming the Cuyahoga River from a place of industrial waste to a place of natural beauty and socioeconomic opportunity. Thus, urban river restoration presents an opportunity for novel placemaking: a local microcosm of the global turn towards urban sustainability. However, there is …
The Role Of Urban Forests In Mitigating Flooding Effects: A Case Study In Savannah, Georgia, Gillian Bush
The Role Of Urban Forests In Mitigating Flooding Effects: A Case Study In Savannah, Georgia, Gillian Bush
Undergraduate Theses, Capstones, and Recitals
Flooding in coastal communities is shaped by the interaction between natural systems and urban development. Chatham County, a low-elevation region in the Savannah, Georgia metropolitan area along the eastern coast of the United States, is prone to coastal storms and frequently affected by flooding. It serves as a useful case study to better understand the factors behind flooding and the areas that are most at risk. This study uses GIS-based analysis to examine the overlap between flood risk, urban forest cover, and impervious surfaces. The results indicate elevated vulnerability along major transportation corridors and barrier islands, where high-risk flood zones …
Quantifying Terrain Controls On Satellite-Based Snow Water Equivalent Estimation: A Spatially Explicit Machine Learning Approach, Brant Giovannetti
Quantifying Terrain Controls On Satellite-Based Snow Water Equivalent Estimation: A Spatially Explicit Machine Learning Approach, Brant Giovannetti
Geography and the Environment: Graduate Student Capstones
Terrain variables are widely incorporated into machine learning Snow Water Equivalent (SWE) models but are rarely evaluated for their independent contribution relative to spectral predictors. Using a four-tier stepwise Random Forest framework with Harmonized Landsat Sentinel-2 imagery and Airborne Snow Observatory LiDAR ground truth, this study isolates the contribution of elevation, slope, northness, and eastness across Peak and Ablation snowpack regimes in the East Taylor River Watershed, Colorado. During peak snowpack, adding terrain improved R² by 0.214, with elevation alone accounting for 42.8% of model importance. During ablation, full-dataset terrain gains were modest, increasing R² by only 0.036. However, when …
Tracing The Flow Of Value In Ecotourism: A Case Study Of Lekki Conservation Center, Lagos, Nigeria, Queen Oluwatobi Olafadehan
Tracing The Flow Of Value In Ecotourism: A Case Study Of Lekki Conservation Center, Lagos, Nigeria, Queen Oluwatobi Olafadehan
Electronic Theses and Dissertations
This study examines the flow of value in ecotourism at Lekki Conservation Center (LCC) in Lagos, Nigeria, using a political ecology framework to analyze how economic benefits, participation opportunities, and environmental impacts are distributed among different community groups. Drawing on semi-structured interviews with 16 community members, participant observation, and photographic documentation, the study investigates how surrounding communities perceive and experience ecotourism, how revenue is understood to be distributed, and in what ways communities are included in or excluded from conservation decision-making. The findings reveal that ecotourism at LCC generates benefits that are unevenly distributed, that community participation in governance remains …
Not Everyone Gets A Tree: Housing Values, Street Trees, And Equity In Portland, Matthew Moller
Not Everyone Gets A Tree: Housing Values, Street Trees, And Equity In Portland, Matthew Moller
University Honors Theses
Street trees are positively associated with Portland home sale prices, but exposure and capitalization are uneven by race/ethnic neighborhood context. Urban trees are ecological assets, but their economic and equity implications remain uneven. This thesis examines street-tree exposure and 2023 residential sale prices in Portland, Oregon (n = 6,414) using a mixed-methodology hedonic design. Ordinary least squares models measure inventoried street-tree counts within 20m, 50m, and 100m buffers together with structural controls and census-block racial and ethnic context. Trees are positively and significantly associated with logged prices at all radii, with scale-sensitive magnitudes and modestly better fit as wider buffers. …
Urban Sacred Grove: A Visioning For Collective Care, Preservation, Environmental Justice, And Resilience, Oluwadara A. Ojugbele
Urban Sacred Grove: A Visioning For Collective Care, Preservation, Environmental Justice, And Resilience, Oluwadara A. Ojugbele
Dissertations, Theses, and Capstone Projects
My capstone explores how the concept of sacred groves—a community-based practice of conserving forest areas for cultural, spiritual, or religious purposes—can be reimagined as a framework for urban environmental stewardship and community care. Sacred groves have historically varied across time and place but consistently serve as protected spaces that honor divine forces, ancestors, and community values. In the Yoruba context, groves demarcate lush forests as abodes for oriṣas (divine forces) and spiritual beings, often containing shrines and artifacts that embody cultural beliefs. My capstone draws on the sacred grove concept and aims to illustrate how urban communities might adopt sacred …
Erosion And Accretion: Mobilities Of Sand, People, And Memory At Queer Riis Beach, Jah Elyse Sayers
Erosion And Accretion: Mobilities Of Sand, People, And Memory At Queer Riis Beach, Jah Elyse Sayers
Dissertations, Theses, and Capstone Projects
The People’s Beach at Jacob Riis Park on the Rockaway Peninsula of Queens, New York, is a vibrant place of queer and trans public-space placemaking—and especially Black and working class queer and trans placemaking. A distinct queer ecology emerges in the interplay of the dynamic movement of the barrier island, queer and trans—especially queer and trans Afro-diasporic—mobilities. This queer ecology, while articulated with, also defies and exceeds logics and workings of private property. In response to a convergence of pressures on Black, queer, trans, and working-class placemaking on the beach site in the 2020s, beachgoers have mobilized longstanding provisional socialities …
Visualizing Ozone Pollution In The Denver Metro Area Using A Bioindicator Garden, Ella K. Mathews, Hillary Hamann, Julie Morris, Erica L. Larson
Visualizing Ozone Pollution In The Denver Metro Area Using A Bioindicator Garden, Ella K. Mathews, Hillary Hamann, Julie Morris, Erica L. Larson
DU Undergraduate Research Journal Archive
Since the industrial revolution, widespread fossil fuel combustion has significantly increased atmospheric pollution. The combustion of fossil fuels releases nitrogen oxides (NOx) and volatile organic compounds (VOCs), which form tropospheric (ground-level) ozone when exposed to sunlight. Ozone directly harms plants by disrupting their ability to absorb carbon dioxide, release oxygen, and carry out photosynthesis. Bioindicator species are plants that have visible responses to environmental conditions, such as ozone, and can act as “canaries in the coal mine,” indicating the health of their environment. In this study, we used a garden of ozone bioindicator species (ozone garden) as a cost-effective tool …
King Of The Jungle: Comparative Analysis Of The Geopolitical Narratives Surrounding Fordlandia And A Proposed Resort Park In El Mirador, Rachel Jaeger
King Of The Jungle: Comparative Analysis Of The Geopolitical Narratives Surrounding Fordlandia And A Proposed Resort Park In El Mirador, Rachel Jaeger
DU Undergraduate Research Journal Archive
Environmental geopolitics is a field of study in which narratives about the environment are analyzed to reveal the underlying motivations and objectives they support. Using Shannon O’Lear’s (2020) framework of environmental geopolitics, I conduct a comparative analysis of the narratives surrounding two distinct development projects: Henry Ford’s historical company town in the Brazilian Amazon, Fordlandia, and a proposed ecotourism resort park in El Mirador, Guatemala. Analysis of Fordlandia reveals a narrative of American frontierism and a man-versus-nature perspective that served to paint the environment as belligerent and thereby justify corporate control and Indigenous assimilation. Narratives surrounding El Mirador differ, representing …
Automation, Migration, And Development: Geography Of Job Precarity In South Asia And North Africa, Keshav Bhattarai, Ambika P. Adhikari
Automation, Migration, And Development: Geography Of Job Precarity In South Asia And North Africa, Keshav Bhattarai, Ambika P. Adhikari
Himalayan Research Papers Archive
This article examines how accelerating automation and the adoption of artificial intelligence (AI) in advanced economies reshape labor markets across the Global South through interconnected channels of production, migration, and remittances. Drawing on the theories and practices of economic geography, labor economics, and development studies, the analysis conceptualizes automation as a transnational shock that contracts demand for migrant labor while simultaneously amplifying employment precarity in labor-surplus economies. The article advances a geographically grounded framework linking technology adoption in core industries with labor displacement, youth unemployment, and urban labor saturation in South Asia and North Africa. It further highlights the macroeconomic …
Building Collaborative Capacity For Coexistence With The Montana Beaver Working Group, Shane Randle
Building Collaborative Capacity For Coexistence With The Montana Beaver Working Group, Shane Randle
Graduate Student Portfolios, Professional Papers, and Capstone Projects
Despite beavers’ recent surge in popularity, prevailing negative attitudes and the persistence of beaver removal practices remain obstacles for those advocating living with beavers. The Montana Beaver Working Group (BWG) advances beavers’ role in ecological and community resilience through members’ collaborative efforts, including beaver-related restoration and conflict resolution projects. Bringing together people with diverse values and perspectives, the BWG builds collective understanding, develops a holistic vision for beavers in Montana, and supports members in pursuing it. As the group’s impacts and membership have grown, so too has their need to adapt. For my Civic Engagement Project, I strengthened the BWG’s …

Elevational Patterns Of Microplastic Density In The Surface Water Of Remote Mountain Lakes In The Swiss Alps, Nora Gutzwiller
Elevational Patterns Of Microplastic Density In The Surface Water Of Remote Mountain Lakes In The Swiss Alps, Nora Gutzwiller
Electronic Theses and Dissertations 2020 - Present
This novel study investigates the presence, distribution, and possible drivers of microplastic (MP) pollution in 15 alpine and subalpine lakes in the Swiss Alps. A total of 35 surface water samples were collected and analyzed under a microscope to identify and classify MPs by size, shape, and color. MPs were found in all lakes, with small fibers being the most abundant type, suggesting that atmospheric processes are a key transport pathway. Contrary to expectations, MP levels showed no significant relationship with elevation, temperature, pH, or distance to anthropogenic features, indicating that broader environmental processes likely control their distribution. However, clear …
Scientific Research In Cuba: A General Analysis With A Special Focus On Energy, Agriculture And Technology, Henri Dou, Pierre Fournie
Scientific Research In Cuba: A General Analysis With A Special Focus On Energy, Agriculture And Technology, Henri Dou, Pierre Fournie
International Journal of Islands Research
An analysis of science in Cuba is carried out using data from the OpenAlex database. Examples are developed: agriculture, rice, technology in relation to the current situation: national food supply, energy and medicine. The predominance of research in biology and medicine and the low commitment in the fields of agriculture, energy, medicinal plants and technology are highlighted. Various development schemes are proposed. The conclusion is that research must be directed towards strategic areas: food and energy, must be less dispersed and that technology must be better taken into account. Three proposals are made: the development of a chemical analysis platform …
Sustainability, Culture, And Higher Education: An Autoethnographic Sustainability Comparison Of The Sustainability Initiatives At The University Of Salzburg And Bowling Green State University, Madison Alt
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 …
Impact Of Living Shorelines On Coastal Morphology And Sedimentology, Sydney Garber
Impact Of Living Shorelines On Coastal Morphology And Sedimentology, Sydney Garber
Electronic Theses and Dissertations 2020 - Present
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 …

The Courts Closest To The People: The Battle Between Populism And Democracy In The U.S. District Courts, Shruti Rana
The Courts Closest To The People: The Battle Between Populism And Democracy In The U.S. District Courts, Shruti Rana
Midwest Social Sciences Journal
The U.S. district courts have emerged as a critical site of contested terrain amid the chaos and controversies consuming American law and politics since the start of the second Trump administration. This article examines these frontline courts through the theoretical lens of populism, arguing that they have become a critical institutional flashpoint in the populist assault on constitutional democracy in the United States. As the courts closest to the people, the district courts occupy a unique structural position: They are the fact-finding courts, the most geographically dispersed and professionally diverse tier of the federal judiciary, and often the first institutional …

Rising Numbers, Rising Risks: Population, Growth, And Natural Disasters, Sophia Becker-Toro, Yu Ouyang
Midwest Social Sciences Journal
How does population size and growth affect the risk of natural disasters? On October 7, 2024, before Hurricane Milton makes landfall in the Tampa Bay area, Tampa Mayor Jane Castor issues a dire warning to affected citizens: “I can say without any dramatization whatsoever. If you choose to stay in one of those evacuation areas, you’re going to die.” While there is an extensive literature which focuses on the impact of climate change and/or natural disasters, there is a dearth of works on how population affects the risks of natural disasters. As both the frequency and severity of storms and …
