The Palm Farm Next-Door: Land Concessions, Livelihoods, And Nutrition In Plantation-Adjacent Communities, Julia Entwistle

Electronic Theses and Dissertations

Large-scale land concessions have reshaped agrarian landscapes globally, yet their implications for community land tenure, livelihoods, and nutrition remain unevenly understood. This dissertation examines how plantation agriculture and foreign investment have transformed land access, labor relations, and food systems in Liberia, a country with one of the highest proportions of land under concession globally. Guided by a political ecology framework, the study employs a mixed-methods design integrating policy analysis, in-depth interviews, and household surveys across two palm oil concession sites. The findings show that ambiguous land policies historically facilitated dispossession, while recent legal reforms have enabled communities to strategically mobilize …

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 …

Geospatial Governance Failures In The Department Of Defense: Contractor Noncompliance, Ai Adoption, And The Parallel Treatment Of Gis And Cybersecurity, Lyndsey Olmstead

Geography and the Environment: Graduate Student Capstones

The Department of Defense's treatment of geographic information systems and cybersecurity as parallel rather than integrated policy domains produces geographically predictable vulnerability patterns across its global military installation footprint. This capstone investigates that conclusion through original spatial analysis, constructing a five-variable composite geospatial vulnerability index across the six U.S. Combatant Command regions using publicly available unclassified data. EUCOM ranked highest overall, driven by GPS/PNT spoofing density, commercial satellite coverage, and cyber incident frequency; CENTCOM ranked second, driven by OSINT exposure incidents and governance risk. The null hypothesis of random geographic distribution is rejected. Findings confirm the structural governance gap documented …

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 …

The Shrinking Caspian Sea: Eco‐Hydrological Responses To Human And Climate Pressures, Jesse Duku, Mohammad J. Tourian, Marzi Azarderakhsh, Rovshan Abbasov, Ali Mehran, Ali Torabi Haghighi, Stefanos Xenarios, Azara Boschee, Salih Babagiray, Mojtaba Sadegh, Nima Shokri, Ali Nazemi, Alireza Farahmand, Samaneh Ashraf, Temur Khujanazarov, Elmira Hassanzadeh, Dalal Najib, Daniel Placht, Shamshagul Mashtayeva, Ekaterina Rets, Hamid Norouzi, Kaveh Madani, Manoochehr Shirzaei, Hossein Shafizadeh-Moghadam, Chiyuan Miao, Ali Mirchi, Shuo Wang, Amir Aghakouchak

Publications and Research

The Caspian Sea, the Earth's largest inland water body, faces water level decline, drawing comparisons to the collapse of the Aral Sea. Unlike the Aral Sea, the relative roles of climatic variability, hydrological changes, and anthropogenic pressures on the Caspian Sea remain poorly understood. Here, we integrate satellite observations, in situ hydrological records and reanalysis data to examine recent drivers of the Caspian water loss. We show that total river inflow to the Caspian Sea has declined significantly, primarily due to reduced discharge from the Volga River. At the same time, precipitation over the basin has remained broadly stable, while …

An Exploratory Study: The Presence Of Imposter Syndrome In New Graduate Allied Health Professionals And Its Relationship To Location Of Practice, Samantha J. Barber, Carol A. Flavell Dr, Moira Smith Dr

Internet Journal of Allied Health Sciences and Practice

Purpose: Imposter syndrome (IS) explores the feelings of fraudulence within personal and professional settings. Commonly IS results in impaired self-confidence, and self-perceptions of one’s own abilities, their mental health, and places them at a higher risk of burnout. Imposterism is linked to transitionary periods, such as being newly graduated, and while IS addressed amongst the medical community [doctors and nurses], there is a gap in literature relating to IS amongst allied health professionals (AHPs). Additionally, there is no known literature in which IS presence or severity is explored in relation to an individual’s geographic location. The aim of this study …

Canyon Ferry Reservoir: A Regional Recreation System In Montana, Kika Bradford, Melissa Weddell

Institute for Tourism and Recreation Research Publications

This study examines recreation use, visitor behavior, and infrastructure demands at Canyon Ferry Reservoir, Montana, using a combination of visitor surveys, automated counts, and systematic observations conducted between February and October of 2025. Results indicate that Canyon Ferry functions primarily as a high-frequency, locally driven recreation system characterized by repeat visitation, small travel groups, and short-duration trips. Use is highly concentrated at a limited number of sites and during predictable peak periods, creating localized infrastructure pressures despite relatively stable overall visitation levels. Findings show that parking areas and campgrounds experience more consistent capacity constraints than boat ramps, and that perceptions …

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 …

Substations In The Digital Economy: Fiscal And Political Geographies Of Data Centers In Georgia, Jacqueline Wright

Geography Undergraduate Senior Theses

In recent years data center construction has drastically increased around the world, especially in the U.S. Building out the infrastructure of the digital economy consumes water, electricity, and capital at great scale, drawing resources from public use towards regimes of private accumulation. This thesis takes Metro Atlanta as a particular microcosm within international digital infrastructure buildout, first worth investigating on its own terms, but also for lessons that may reach across the broader geography of the digital economy. This thesis takes up concerns with the politics of data centers siting, how these projects fit into narratives of economic development, and …

Transit Infrastructure And Neighborhood Change: The Impact Of The Q Train Expansion On Commercial Space Use In New York City's Upper East Side, Lily E. Levick

Quantitative Social Science Undergraduate Senior Theses

This paper examines the impact of the 2017 Second Avenue Subway expansion on commercial land uses on New York City’s Upper East Side. The research leverages quantitative models alongside qualitative personal experiences and literature to understand the relationship between infrastructure, space, and neighborhood change from a nuanced perspective. The results show that the studied area experienced a broad trend of de-commercialization between 2003 and 2025, and a simultaneous shift toward commercial zoning in areas closest to new subway stations. These findings encourage us to consider how mobility access is an important driver for change within neighborhoods and urban space, and …

Can Chinatown Speak? Mapping Hauntings, Dispossessions, And Diasporic Lifeworlds In Boston’S Chinatown, Lin Lin

Geography Undergraduate Senior Theses

Boston's Chinatown has persisted despite highway construction, urban renewal, and institutional expansion that destroyed much of the neighborhood. This thesis asks how residents have shaped and inhabited that space and whose contributions have been forgotten in the process. Through entangling frameworks from Geography and Asian American Studies, the thesis approaches Boston's Chinatown through walking, archiving, and counter-mapping. The first chapter reads the streets as a layered record of historical ruptures, which leads to a dichotomy of presence and absence. The second chapter then examines the archives of the 1993 Parcel C struggle. It creates an original counter-archive, titled the "Collection …

Flood Risk Assessment And Water Diversion Scenarios For Terre Haute, Indiana Based On Time-Series Remote Sensing And In-Situ Measurements, Hung Q. Ha

2026 Spring Reports (Terre Haute)

The City of Terre Haute has faced growing concerns over the increasing frequency and intensity of riverine flooding along the Wabash River, alongside risks associated with urban inundation. To create more safely floodable areas – specifically by locating wetland areas using GIS and researching government ordinances on development in those areas – the City of Terre Haute sought to better understand flood patterns and identify viable floodwater diversion strategies. The project was formally titled as “Pattern of Flooding along the Wabash River in Vigo County and Scenarios for Floodwater Diversion”. Faculty and students from Geospatial Intelligence Lab, Department of Earth …

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

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 …

Engineering Immunity? Biotechnical Governance And The Experimental Failures Of Project Wolbachia In Singapore, Siew Ying Shee, Orlando Woods, Sayd Randle

Research Collection School of Social Sciences

This paper introduces the idea of ‘experimental failure’ to critically interrogate the limits of engineering biological systems for urban governance. Whilst experimentation through projects related to smart cities and eco-cities has garnered significant attention, biotechnical experiments––which manipulate living organisms through technology––remain underexplored. Unlike interventions leveraging non-living, inanimate systems, engineering life must contend with ecological ‘unruliness’ and social uncertainties. These complexities often resist straightforward quantification and exceed conventional evaluation frameworks, demanding a rethinking of what constitutes ‘success’ and ‘failure’ in such interventions. Drawing on ethnographic research with public health officers, pest management professionals and residents in Singapore, we analyse the government-led …

Potential Recyclable Materials In Buildings: A Framework For Greenhouse Gas Emissions Assessment Of Residential Buildings In Singapore, Pradeep Alva, Riccardo Talami, Wanyu Pei, Goran Sibenik, Martin Mosteiro-Romero, Clayton Miller, Rudi Stouffs

Research Collection College of Integrative Studies

As countries aim to reduce resource consumption and greenhouse gas (GHG) emissions, Whole Life Carbon Assessment (WLCA) has become a vital method for quantifying embodied and operational GHG emissions. However, few studies have conducted WLCA on an urban scale, often addressing operational or embodied GHG emissions in isolation without considering their cumulative impact. This study introduces a city-wide WLCA framework to assess the potential recyclable materials of urban building stock, using Singapore as a case study with 5915 public residential buildings. Upfront GHG emissions are calculated from material intensity and building information, while operational emissions are based on energy use …

On The Brink Of Silence: Ethnographic Perspectives On Hunting And Forest Life Among The Awa Guajá In Eastern Amazonia, Uirá Garcia

Tipití: Journal of the Society for the Anthropology of Lowland South America

The central theme of this article basically resides in the relationship established by indigenous peoples between their hunting practices and the forest. Indigenous ways of connecting ‘hunting’ and ‘forest’ necessarily pass through other modes of knowing, only marginally – if it all – dependent on vision. On the contrary, sounds, smells and even dreams are, for many South American indigenous collectives, more trustworthy indices than what the eye sees. This article divides into two parts. In the first, I set out the main ideas related to the anthropological study of hunting in Amazonia at a conceptual level. In the second, …

El Amor En Los Tiempos Del Caucho. Pactos Matrimoniales Y Trabajo Coercitivo Entre Awajún Y Patrones En La Amazonía Peruana, Silvia Romio

Tipití: Journal of the Society for the Anthropology of Lowland South America

Este trabajo presenta un análisis etnohistórico de los cambios en la jefatura awajún del Alto Marañón a inicios del siglo XX, centrándose en sus relaciones de dependencia, poder y trabajo forzoso con los comerciantes mestizos, en su mayoría patrones del caucho establecidos en la zona. El ensayo describe la transformación gradual de las relaciones cotidianas con estos foráneos, quienes pasaron de ser simples aliados comerciales a convertirse en capitanes y, finalmente, en yernos-patrones mediante el matrimonio con una o más hijas del jefe indígena. A través de la figura del yerno-patrón, se produjo una progresiva incorporación del “blanco” a …

A Pedra Da Aldeia: Reativações Waiwai Entre A Antropologia E A Arqueologia De Longa Duração, Carlos Machado Dias Jr., Kanhera Renato Xerew, Alexandre Aniceto Souza, Jaime Xamen Wai Wai, Justino Sarmento Rezende, Claide De Paula Moraes

Tipití: Journal of the Society for the Anthropology of Lowland South America

O artigo analisa um episódio ocorrido na comunidade waiwai do Jatapuzinho, na Terra Indígena Trombetas-Mapuera, envolvendo o encontro do professor Renato Kanhera Waiwai com um antigo Pote de Pedra encontrado às margens do rio Jatapuzinho durante um período de estiagem. A partir de uma experiência etnográfica conduzida pelo próprio Kanhera, os autores refletem sobre os efeitos cosmopolíticos, históricos e ontológicos mobilizados pelo artefacto, articulando antropologia, arqueologia e perspectivas indígenas em um exercício de escrita coletiva. O texto argumenta que o Pote de Pedra não constitui apenas um vestígio arqueológico, mas um agente ativo na reativação de memórias, sonhos, narrativas e …

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

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 …

Five Corridors: A Community Health Needs Assessment Of Horry County, Stephen Borders, Hayley Bilko, Molly Craig, Olivia Guthrie, Ashley Mcconnell, Emily Mcgowan, Anna Quick, Abigail Rike, Makayla Wilson

Public Health

This report presents a Community Health Needs Assessment (CHNA) of Horry County, South Carolina. Its central analytical contribution is a five-corridor framework derived from k-means cluster analysis of the county's 76 residential census tracts, drawing on social and economic indicators from the American Community Survey and health estimates from the CDC PLACES program. The analysis organizes the county into five distinct community types — Affluent Coastal Retirement, Moderate Coastal Retirement, Inland Rural/Suburban Transitional, Concentrated Disadvantage, and Hispanic Hospitality Worker — each with a characteristic profile of social and health conditions.

Within this framework, the assessment examines a range of social …

Perceptions Of Care: An Exploratory Case Study On Residents’ Perceptions Of Neighborhood And City Maintenance, Taylor Coats

Transforming Communities

Where one lives impacts both their physical and mental well-being. Though one’s builtenvironment is an important factor, the perception of one’s environment influences mental well-being. This qualitative study examines what influences residents’ perceptions of theirneighborhood and local governmental efforts to maintain and improve their community. Thisstudy utilized a case study methodology to interview residents, stakeholders, and politicians intwo neighborhoods in a mid-sized urban city in the Midwest (N = 16). This study identified threecore aspects that influence participants' perceptions of their neighborhoods and city efforts tomaintain and improve their community: 1) history with the city; 2) geographic location withinsegregated neighborhoods; …

Tùn-Scene And A-Futurism: Biomythography, Opacity, And Posthuman Imagination, Minglu Du

Masters Theses

Grounded in the author’s position as a Chinese feminist, this thesis examines how East Asian women, as well as East Asian-coded femininity more broadly, are objectified and othered within futurist visual culture in the age of artificial intelligence. Through an engagement with ornamentalism, techno-Orientalism, and posthumanism1 , it argues that the persistent figure of the feminized humanoid cyborg continues to reproduce colonial and patriarchal structures of desire, rendering marginalized bodies as fetishized and violable surfaces. In response, the thesis develops Tùn-Scene, a biomythographic artistic framework and the first experiment in what the author provisionally names A-Futurism. Drawing on Donna Haraway’s …
