Black Ecological Care: Conservation, Environmental Justice, And Sovereignty In Baltimore, Maryland, Alexandria Nicole Casteel
Dartmouth College Ph.D Dissertations
Dominant traditions of urban planning, municipal policy, and environmental science register Black urban spaces through a vocabulary of pathology, as sites of ecological deficit, contamination, and social decay. This dissertation investigates how Black communities in U.S. cities attend to the environment in ways that address legacies of environmental and social injustice while opening pathways toward different environmental futures. I gather these practices under the analytic of Black ecological care, which captures the generative labor of making and maintaining livable worlds within, alongside, and beyond histories of harm. I develop the analytic across twenty-nine months of ethnographic fieldwork in 2021 and …

The rapid expansion of photovoltaic (PV) deployment demands integrated environmental and economic evaluation of emerging technologies. This study compares crystalline silicon (c-Si), perovskite, and hybrid perovskite-silicon tandem PV systems using a cradle-to-grave Life Cycle Assessment (LCA) combined with Techno-economic Analysis (TEA) to measure environmental impacts, resource efficiency, and cost performance. Environmental indicators include life cycle greenhouse gas emissions, total energy demand, water use, and overall impact, while economic performance is assessed through levelized cost of electricity (LCOE). Sensitivity analysis explores the effects of energy payback time (EPBT), material efficiency, and perovskite stability. Results show manufacturing as the main hotspot, contributing …
Evaluating Quahog (Mercenaria Mercenaria) Nursery Methods And Production Costs To Support Diversification Of Maine’S Fisheries And Aquaculture Sector, Hannah G. Wolf
Honors Theses
Populations of wild and farmed quahogs in Maine are expanding, driven by warming waters, declining soft-shell clam populations, and the need to diversify fisheries. The Northern quahog (Mercenaria mercenaria) is a potential species to diversify Maine’s marine sector, as its geographical range is expanding, and they appear more resistant to green crab predation. Enhancing wild quahog stock provides economic and social advantages for both the aquaculture and wild harvest industries. However, there is limited understanding about the commercial viability of producing quahog seed on existing farms for wild shellfish enhancement in Maine. This research, part of a larger NOAA …

Discovery, The Student Journal of Dale Bumpers College of Agricultural, Food and Life Sciences
Tall fescue (Lolium arundinaceum (Schreb.) S.J. Darbyshire) infected with toxin‑producing fungi can induce fescue toxicosis in grazing ruminants, reducing performance and altering forage intake. Chemical compounds in red clover (Trifolium pratense), such as biochanin A, have been proposed to mitigate these effects by improving palatability and blood vessel relaxation. This study examined whether the inclusion of ground red clover (GRC), either alone or in combination with hydroxypropyl methylcellulose (HPMC) and polyethylene glycol (PEG), affected voluntary diet selection in lambs offered toxic fescue. Thirty‑three lambs were housed individually and assigned randomly to one of four diets: (1) toxic …

An Ecological-Evolutionary Investigation Of Phenotypic, Genetic, And Environmental Variation And Correlations Among Reproductive Traits Of Tall Goldenrod (Solidago Altissima), Michael J. Wise, Daniel Lavy, David E. Carr, Warren G. Abrahamson Ii
Faculty Journal Articles
Although fitness-related traits are expected to be under strong selection, traits related to reproduction are often quite variable within plant populations. We used data from two large greenhouse experiments to quantify phenotypic, genetic, and environmental variation, as well as genetic tradeoffs that might help explain the maintenance of withinpopulation variation in four traits related to sexual or vegetative reproduction in tall goldenrod (Solidago altissima). The goldenrod population exhibited high levels of both phenotypic and genetic variation for capitulum (flower head) number and size, seed production, and rhizome growth. Significant negative genetic correlations were present between the number of capitula and …

Reactionary Radicals, Radical Reactionaries: A Review Of Against The Machine: On The Unmaking Of Humanity, Michael Kirby
Publications and Research
Paul Kingsnorth, in his book Against the Machine: On the Unmaking of Humanity, asserts that the ecological destruction, consumerism, and social atomization that have come to define contemporary life are the product of a malevolent force he calls the Machine. This review finds that his proposed solution to these crises, namely a return to "traditional" forms of family and community, insufficiently addresses the material and structural conditions underlying the capitalist mode of production. Kingsnorth’s dismissal of Marxism is then interrogated by juxtaposing his critique of the Machine with Marx’s analysis of estranged labor. Finally, this review concludes that the …

Umbilical Cord Connections: Ban Huay E Kang Women's Ecological Knowledge Transmission And Mobilization, Areerat Worawongwasu, Yuting Zhou, Phyo Su San
Forest and Society
In the Pga K’nyau village of Ban Huay E Kang in the Chiang Mai province of northern Thailand, a newborn's umbilical cord is placed inside a bamboo container and hung from a tree. This is a sacred act of establishing a lifelong connection between each villager and the forest. The practice is known in the Pga K’nyau language as de paw thoo. This tradition has faced significant disruption from state-led conservation policies and the institutionalization of childbirth in state hospitals, which Ban Huay E Kang villagers contest through their revitalization of de paw thoo. Based on collaborative ethnographic research, …

A Deep Learning Approach For Mapping Shrubs, Wet Tundra And Surface Water In Arctic Tundra With Very High Resolution Satellite Imagery, Darko Radakovic
A Deep Learning Approach For Mapping Shrubs, Wet Tundra And Surface Water In Arctic Tundra With Very High Resolution Satellite Imagery, Darko Radakovic
Theses, Dissertations and Culminating Projects
Arctic shrub expansion threatens to accelerate permafrost thaw through complex feedbacks, yet whether shrubs primarily indicate or drive degradation remains unresolved. This dissertation integrates deep learning analysis of two decades of satellite imagery with LiDAR canopy structure and radar soil moisture data to reveal that shrubs play a dual role: young, expanding shrubs signal active permafrost thaw, while mature, tall shrubs stabilize underlying permafrost through insulation. By demonstrating that vertical canopy structure predicts thaw depth better than cover extent alone, this work establishes a scalable framework for monitoring permafrost vulnerability across the rapidly changing Arctic. Arctic shrub expansion is accelerating …

Work Analysis And Competency Modeling In Effective Circular Economy Implementation, Katherine C. Wheeler, S. Burak Ozkum
Faculty Publications – Psychology
First paragraph in lieu of abstract:
In their focal article, Schilling et al. (2026) specifically illustrate how interorganizational and intraorganizational cooperation are the most critical areas through which I-O psychology can contribute to a sustainable circular economy (CE) transition. This commentary elaborates on the application of I-O psychology by highlighting how work analysis and competency modeling enable effective CE implementation through organizational cooperation. Transitioning from a linear to a CE represents a major organizational change. During this change, organizations must ensure that their systems remain aligned. Work analysis and competency modeling are crucial to this alignment.

Parks Under Pressure: Policy Threats And Advocacy Coalition Resistance In 2025, Rachel Supnick
Parks Under Pressure: Policy Threats And Advocacy Coalition Resistance In 2025, Rachel Supnick
CMC Senior Theses
This thesis examines the 2025 policy changes affecting the National Park Service (NPS) and their implications for the agency’s mission and advocacy coalition. Historically a bipartisan and widely trusted agency, the NPS has evolved from a conservation-focused mandate into a complex institution balancing environmental protection, recreation, scientific research, and cultural interpretation. Recent policy actions represent not only operational disruption but an unprecedented politicization of the Park Service, reflecting a shift toward centralized executive control. These changes have constrained the agency’s ability to fulfill its mission and placed it within broader ideological conflicts over land use, historical interpretation, and federal authority. …
Decomposing Carbon Intensity In U.S. Imports: Trade Composition Vs. Technological Change From 2000-2019, Alyssa K. Wong
Decomposing Carbon Intensity In U.S. Imports: Trade Composition Vs. Technological Change From 2000-2019, Alyssa K. Wong
CMC Senior Theses
This paper examines whether the increasing share of U.S. manufactured imports from China between 2000 and 2019 affected the carbon intensity of U.S. consumption. Bilateral trade data from BACI are combined with emissions data from the OECD Inter-Country Input-Output framework to construct a measure of carbon intensity defined as emissions embodied per dollar of imports at a country level. Changes over time are decomposed into composition effects, driven by shifts in import shares, and technique effects, driven by changes in emissions intensity within exporting countries. Carbon intensity declines substantially over the period. While increased imports from China would have raised …

Estimating Sediment Properties Using A New Source Level Function For Wind-Driven Underwater Sound Derived From Long-Term Archival Data, S Bruce Martin, Martin Siderius
Electrical and Computer Engineering Faculty Publications and Presentations
Wind-driven breaking waves generate the background sound throughout the ocean. An accurate source level for wind-driven breaking waves is needed for estimating the ambient sound levels needed for sound exposure modeling, environmental assessments, and assessing the detection performance of sonars. Previous models applied a constant roll-off of sound levels at -16 dB/decade at all wind speeds, and these models' source levels were flat at frequencies below ∼1000 Hz due to a lack of measurements. Here, we analyzed 16 long-term archival datasets with limited anthropogenic sound sources to estimate the wind-driven source level down to 100 Hz. We estimated the site-specific …
The Evolution Of California Wildfire Governance Through State Bills, Regulations, And Executive Actions, Cassandra Dawn Blevins
The Evolution Of California Wildfire Governance Through State Bills, Regulations, And Executive Actions, Cassandra Dawn Blevins
History and Political Science | Senior Theses
California faces an escalating wildfire crisis, driven by climate change, drought, and development in fire-prone areas. Despite decades of scientific research on wildfire behavior and risk reduction, catastrophic fires since 2017 raise a critical question: to what extent have California state laws and policies kept up with the intensifying wildfire crisis? Existing scholarship provides extensive insight into wildfire ecology, land-use planning, fuel management, and community resilience, yet it lacks a comprehensive evaluation of whether California’s legislative, regulatory, and executive actions have adapted in a coordinated and evidence-informed manner. In particular, the literature offers limited analysis of how state laws integrate …
The Impacts Of Wing-Flashing By Northern Mockingbirds On Foraging, Parental Care, And Reproductive Success, Anna R. Starman
The Impacts Of Wing-Flashing By Northern Mockingbirds On Foraging, Parental Care, And Reproductive Success, Anna R. Starman
Undergraduate Honors Theses
Foraging efficiency may be enhanced by flashing patches of white wing and tail feathers and has been documented in several avian species. Northern Mockingbirds (Mimus polyglottos, NOMO) exhibit this “wing-flashing” (WF) behavior while foraging, during displays, and in response to predators. In NOMOs, WF has been hypothesized to increase foraging success, but previous findings are inconclusive. To further investigate the biological role(s) of WF behavior in NOMOs, the ventral surface of white primary feathers of male NOMOs were artificially darkened, and the foraging and provisioning rates of undarkened (control) males and their mates were compared. While foraging, undarkened …

Identifying Socio-Economic Areas Of Concern Towards Inclusion In Gis Hazard Management In Detroit, Michigan., Ernestina Osei
Master's Theses or Doctor of Nursing Practice
This study examined the spatial distribution of socio-economic vulnerability and accessibility to essential services in Detroit, Michigan, using a Geographic Information Systems (GIS)-based approach. The research aimed to identify areas of greatest concern by integrating socio-economic indicators, including poverty, housing vacancy, income, unemployment, and crime, with spatial measures of access to critical infrastructure such as hospitals, fire stations, police stations, and grocery stores. Both feature-based and raster-based analyses were employed, including buffer and overlay analysis, service area evaluation, Euclidean distance modeling, and multi-criteria suitability analysis.
A mixed-methods framework was adopted to combine quantitative spatial analysis with contextual understanding of urban …

From Couriers To City Dwellers: The Changing Human-Pigeon Relationship, Mallory C. Peterson
Undergraduate Theses, Professional Papers, and Capstone Artifacts
Their coos echo off the walls of skyscrapers and their wings beat faster than the cadence of footsteps. Whether dodging cars or pecking at food scraps, pigeons are a constant character of urban environments. Their unique history has allowed them to raise their young under bridges and on windowsills. Pigeons and humans are inextricably intertwined, to the joy and dismay of many. Once celebrated as couriers, pigeons carried messages of war, love, and survival across vast distances, shaping human connection and history. Today, they are more often dismissed as pests, their presence flattened into the city noise.

Religiosity And Political Affiliation As Moderators For Climate Change Belief, Jenna L. Hiljus
Religiosity And Political Affiliation As Moderators For Climate Change Belief, Jenna L. Hiljus
Doctor of Psychology (PsyD)
Climate change remains a polarized issue in the United States despite broad scientific consensus. The present study examined how specific variables within political ideology (social and economic conservatism) and religiosity (belief, praxis, and morality) relate to climate change belief among undergraduate students at a private Christian university. Participants (N = 130) completed measures of climate change perceptions, multidimensional religiosity, and social and economic conservatism. Correlational analyses showed medium-sized, negative relationships between climate change belief and both social and economic conservatism, with no significant difference between the two domains.
