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 …

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 …

Human biomonitoring (HBM) continues to play an indispensable role within exposure science, offering insights into aggregate chemical exposures across populations and life stages. Since 2018, the European chapter of the International Society of Exposure Science Human Biomonitoring Working Group (ISES Europe HBM WG) has aimed to facilitate generation of more and high-quality HBM data. The working group aims to strengthen integration of HBM data into regulatory frameworks through improved study design, harmonized methodologies, and enhanced reporting practices. Key achievements in the past seven years include the harmonization of HBM metadata through development of minimum information requirements for HBM (MIR-HBM), development …

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 …

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 …

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 …

Historic Coptic Orthodox monasteries in Egypt (HCOMEs) represent an important component of Christian heritage, integrating architectural value with enduring spiritual traditions that reflect both tangible and intangible dimensions. However, contemporary development and changing functional demands are generating transformations that may affect their identity if not carefully managed. Despite extensive scholarship, limited research has systematically examined these transformations through a structured evaluative approach. This study addresses this gap by developing and applying an analytical and evaluation framework to examine how contemporary pressures influence the historical, architectural-spatial, and spiritual identity of HCOMEs, and to assess the effectiveness of monastic responses. The framework …

This paper presents the Enhanced Dingo Optimization Algorithm (EDOA) to reconfigure the radial distribution network with the long-standing problem of active power loss minimization while maintaining a stable and acceptable voltage profile. EDOA enhances the standard Dingo Optimization Algorithm (DOA) through the integration of adaptive search control, elite-guided local refinement, and crossover-based diversity preservation mechanisms tailored for distribution network reconfiguration problems. The proposed method has been tested on two test systems: the IEEE 33-bus standard as well as the real-world Ayepe 34-bus distribution feeder in Ibadan, Nigeria. In the IEEE 33-bus test system, EDOA reduces active power loss by 56.00%; …
