The purpose of this study is to explore the phenomenon of the influential element of dress, specifically within royal costume. Within the public spotlight, the reach and impact of appearance accumulate more attraction and influence. This research focuses …
Quantifying Amendment Impact On Microbial Respiration Rate, Qwynn Starrwalker
Quantifying Amendment Impact On Microbial Respiration Rate, Qwynn Starrwalker
Honors Undergraduate Theses
Wetlands play a critical role in the global carbon cycle by acting as carbon sinks, where the flooded anaerobic conditions cause slow microbial respiration compared to other soils. Comparatively more carbon is stored in the soil as organic matter than is released as carbon dioxide (CO2). Making wetland pools of soil organic matter less available to microbes for respiration could reduce overall atmospheric CO2 and slow global warming. This study examined the effect of kaolinite, goethite, and lime on microbial respiration rates in wetland soils under alternating hydrologic conditions. Homogenized soil from a cypress dome was separated …

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 …
The Zoom Town Effect Of Remote Work On Rural Housing Markets, Luc R. Fabing
The Zoom Town Effect Of Remote Work On Rural Housing Markets, Luc R. Fabing
CMC Senior Theses
I study the impact of remote work on rural housing markets, highlighting the moderating role of outdoor recreation amenities. Using panel data from the American Community Survey and Zillow (2010–2024), I employ a Two-Way Fixed Effects model and a shift-share instrumental variable strategy to estimate the effect of work-from-home (WFH) rates on home prices. I find that higher WFH rates are strongly associated with higher home prices in high-recreation counties, but that the association is weak or negative in counties lacking significant recreation amenities. These findings point to amenity migration as a key mechanism through which remote work impacts rural …

Becoming-With The Earth: Contemplative Practice As A Critical Onto-Epistemic Resource For Planetary Belonging, Care, And World-Making, Megan M. Fowler
Electronic Theses & Dissertations (2024 - present)
In an era of accelerating planetary crisis, social work is called to reimagine its theories, methods, and practices beyond anthropocentric frameworks that separate human wellbeing from the health of the Earth and its resplendent living systems. Working in the space of transformative eco-social work, a growing chorus of voices contends that eco-centric responses require broadening the scope of health, welfare, justice, and care to extend beyond the human, to include the more-than-human world upon which all life intimately depends—understandings resonant with Indigenous and other relational knowledge systems long marginalized by colonialist-capitalist-modernity. Drawing from eco-feminist, eco-queer, decolonial, and post-anthropocentric lineages of …
Climate Change In Gilgit-Baltistan: Satellite-Based Land Use/Land Cover Change Detection, Socio-Economic Dimensions, And Adaptation Strategies, Ali Muhammad
Graduate Theses/Dissertations
Climate change is increasingly transforming the cryosphere, hydrology, and human landscape of Gilgit-Baltistan, a highly climate-sensitive mountain region in northern Pakistan. This thesis investigates these transformations through satellite-based land use/land cover (LULC) change detection in four representative tehsils of Gilgit-Baltistan—Ali Abad, Gilgit, Nagar, and Sikander Abad—selected to span a gradient of human pressure and cryospheric exposure within the region. Using summer, cloud-free (< 10%) imagery from USGS Landsat 7 (2000) and Landsat 8 (2025), it conducts a multi-temporal comparison of environmental and socio-spatial change. After atmospheric correction and band compositing, the imagery is classified in ArcGIS Pro into six classes—Water, Barren land, Vegetation, Snow, Glacier, and Built-up—using a Support Vector Machine (SVM) classifier, with Maximum Likelihood Classification and Random Forest also tested but found less suitable for the final workflow. The analysis detects a pronounced reduction in mapped glacier-class area alongside a comparatively stable snow class, together with built-up expansion, while examining how temperature, precipitation, tourism, and population dynamics relate to observed LULC transitions. The results reveal a pattern of cryospheric decline and urban growth, with implications for water availability, ecological stability, hazard exposure, and settlement pressure. By integrating geospatial change detection with climatic and socio-economic interpretation, the thesis moves beyond mapping to explain interacting environmental and human drivers of landscape transformation and provides a reproducible remote-sensing baseline for monitoring land-surface change in heterogeneous mountainous terrain. It recommends integrated water-resource management, climate-resilient land-use planning, watershed and glacier monitoring, and sustainable tourism governance, supporting evidence-based decision-making by the Government of Gilgit-Baltistan and organizations working on climate adaptation, disaster risk reduction, and sustainable regional development.
Complexity Theory And Environmental Conservation Management: A Case Study With Coyote And Red Wolf Hybridization, Gretchen E. Mahalic
Complexity Theory And Environmental Conservation Management: A Case Study With Coyote And Red Wolf Hybridization, Gretchen E. Mahalic
Honors Undergraduate Theses
Conservation biology and invasion biology are value-led scientific disciplines founded on environmental advocacy, operating at the intersection of research and action. Though these disciplines are known for their scientific veracity, unexamined values are often promulgated without scrutiny and drive decisions that work against good ecological outcomes. A case in point is that coyotes migrating into southeastern territory are framed as the greatest threat to the conservation of the endangered red wolf because hybridization is seen as diminishing their species integrity. Applying Val Plumwood’s ecofeminist account of dualistic frameworks, I will use this case to show how the vilification of the …

Growing Agroecology: Two Case Studies From The U.S. Student Farm Movement, Amelia B. Armstrong
Growing Agroecology: Two Case Studies From The U.S. Student Farm Movement, Amelia B. Armstrong
Graduate Student Theses, Dissertations, & Professional Papers
Scholars and activists identify agroecology as a crucial science, practice, and movement to move towards more just, equitable, and sustainable agriculture and food systems. Yet, the exploitative industrial food system, that deepens inequalities like food insecurity (Clapp et al., 2025), reduces farmer autonomy (Rotz, 2015), and contributes to increased carbon emissions (Lin et al., 2011) and biodiversity decline (Rotz, 2015), still dominates. Understanding and mobilizing the different spaces that teach agroecology, then, is a crucial step in challenging the dominant industrial food system. Agroecology education in university settings is an important domain to investigate as potential contributors to this movement, …

Antibiotic pollution is of great interest owing to growing concerns about antibiotic resistance worldwide. This study aims to fabricate acid-modified biochar (CBM-A) from corn plant byproducts (CRs) for sulfamethoxazole (SMX) adsorption in aqueous solutions. CBM-A was synthesized via pyrolysis at 700 °C and modified with 14% H3PO4. Kinetics, isotherms, and thermodynamics were investigated in combination with material characterization to elucidate the adsorption behaviors and mechanisms. The results showed that pyrolysis and acid modification effectively enhanced SMX adsorption by CR because of the increased number of binding groups, specific surface area, and porosity. SMX adsorption on CBM-A was optimized at a …
