Subjective Perspectives On Antarctic Wilderness: An Application Of Integral Ecology, Annabelle G. Mayes

Honors College Theses

Parties to the Antarctic Treaty have set Antarctica aside for peace, scientific research, and environmental protection. However, they have yet to take concrete actions to protect Antarctica’s wilderness values as agreed under the 1991 Protocol on Environmental Protection to the Antarctic Treaty. Meanwhile, pristine areas that are free from human interference are declining as human activity escalates. This study examines perceptions of Antarctic wilderness through the lens of integral ecology. Data from 1,640 people and 16 study populations were extracted from four published studies. Content analysis was conducted to determine how subjective perspectives differ across populations and geographic regions. All …

Colonial Whaling In Walvis Bay And In Southern Africa: Environmental Exploitation And Legacy Of South Africa’S Cetaceans, Jake L. Zarak

Swarthmore Undergraduate History Journal

This paper examines the colonial whaling industry in Southern Africa, with a focus on Walvis Bay, tracing its long term environmental and socio-economic impacts. From the 1700s to the 1900s, whaling operations, primarily led by American, British, and French enterprises, exploited the region’s rich populations of sperm and right whales, drastically reducing their numbers. The study contextualizes whaling within a broader colonial framework, analyzing its effects on whale migratory patterns, indigenous communities, and marine ecosystems. It explores as well, the transition from whaling as an economic endeavor to modern conservation efforts and the romanticization of whales in literature and art. …

Conflict And Community Building In Waste Water Management: The Case Of Azrou Morocco, Jack V. Kalpakian

Peace and Conflict Studies Journal Conference

Climate change is forcing Morocco to institute a wide program of wastewater treatment. Despite legal and bureaucratic problems, the water is being reused directly or indirectly. But the construction of water treatment plants is leading to conflicts with farmers that depended on the untreated water and the use of treated water for green spaces and parks is also often viewed with suspicion. Using the case of the Azrou water treatment plant, this paper argues that while the infrastructure and technical adjustments to climate change have been effective, a gap in understanding between the water managers and the public they serve …

Writing From The Rift: Queer Temporality And The Refusal Of Resolution, Daniela Ruiz Perez

Masters Theses

This thesis develops a phenomenological method for reading speculative literature as a site where queer ecological temporality is experienced rather than explained. Working with Annihilation (2014) by Jeff VanderMeer, The Day of the Triffids (1951) by John Wyndham, and Undrowned: Black Feminist Lessons from Marine Mammals (2020) by Alexis Pauline Gumbs, the project treats reading as a bodily practice shaped by forms of attention. Texts are not interpreted for stable meaning and instead I remain with moments where resolution is withheld. The work is informed by a Marxist attention to how capitalist time organizes labor, productivity, and value, and how …

Urban Forestry In Selected Nepali And Us Cities: Assessment, Analysis, And Recommendations, Ambika P. Adhikari, Keshav Bhattarai

Himalayan Research Papers Archive

Urban forest delivers several benefits to urban area residents. The benefits include shade, dust control, noise mitigation, water retention, ecological services, pedestrian comfort, aesthetic improvements, and economic benefit to the community, including the provision of food.

Urban Sprawl And Residential Carbon Emissions: Evidence From Indonesia And The Philippines, Yi Jiang, Taylor Lathrop, Alexander D. Rothenberg, Yao Wang

Center for Policy Research

This paper studies how neighborhood density affects residential carbon emissions, using detailed data from Indonesia and the Philippines. To address simultaneity, we instrument density with soil characteristics, and to address sorting, we control for community averages of observed characteristics. Unlike cities in developed countries, we find that density is positively correlated with residential energy use. After controlling for sorting, we find a precise null relationship between density and residential carbon emissions. Our results suggest that policies to control urban sprawl may not be successful in reducing residential carbon emissions in developing country cities.

A Study Of The Impacts Of Infusing Data Analysis And Research In An Interdisciplinary Environmental Economics Course, Sean P. Macdonald

Numeracy

This paper explores the impacts of introducing quantitative literacy skills in an interdisciplinary Environmental Economics course typically taught as an issues and policy course without a quantitative component. The study examines the effects of infusing an engaging, student-selected data collection and analysis assignment on students' quantitative reasoning skills, as well as their interest in and attitudes about data analysis and quantitative information. Using data gathered from a set of pre- and post-assessment questions designed to measure changes in quantitative reasoning skills and attitudes, the findings point to significant attitudinal impacts, gains, but smaller, insignificant gains in quantitative reasoning skills.

The Regionalisation Of Blockchain Technology As Asean Cybersecurity Strategy Against Terrorist Financing Through Cryptocurrency, Sabda Ningsih, Syuryansyah Syuryansyah

Global: Jurnal Politik Internasional

Through this study, the authors question how the prospects for ASEAN regionalisation relate to the development of blockchain technology as a cybersecurity medium. Based on previous research, ASEAN is facing a problem of terrorism, which is difficult to handle over time. The finding further exacerbates the fact that transnational terrorist groups have begun to use virtual currency as one of their strategies for funding organisations. Meanwhile, Southeast Asia, according to results of several surveys, includes areas with high numbers of cryptocurrency users, making it a target for blockchain technology companies to establish main offices. Within the framework of ASEAN regionalism, …

Owning The Green Grid: The Political Economy Of Renewable Energy Policy Design, Joshua A. Basseches

Faculty Scholarship

How corporate ownership of the electricity grid matters to state-level renewable energy policymaking.

Historically (and for the foreseeable future), most public policy action in the United States to combat the global climate crisis has taken place at the state level. Former President Joe Biden’s administration marked a significant departure from that trend, as his policies pursued a strategy of “electrify everything” (transportation, buildings, and industry). But who owns the electricity system that is the linchpin of such a strategy, and how does this ownership affect the policy preferences of interest groups at the state level? Owning the Green Grid addresses …

Neanderthals And Their Exhibitions Of Fine Art: Unpacking Neanderthal Art On The European Continent, Jacob T. Simpson

UROP Posters

This research project aims to bridge the gap between anatomically modern humans and our closest genetic relative, Neanderthals. By analyzing research literature on artistically symbolic artifacts potentially created by these ancient humans (focusing on populations in Europe) I hope to offer a superior speculation of Neanderthal intellect. Neanderthals potential capability to create artistic objects could transform our understanding of them and their cognitive abilities, and raise philosophical questions on what it means to be human.

Setting The Recycling Narrative: A Thematic Analysis Of Recycling Webpages In The United States, Haley Nolde

Dissertations and Theses

Recycling is widely promoted in the United States as a central strategy for waste diversion and sustainable materials management, yet recycling outcomes remain inconsistent and public understanding is often fragmented. While substantial research examines recycling behavior, infrastructure, material science, and markets, less attention has been paid to how recycling itself is framed and communicated to the public. This thesis addresses that gap by examining narratives produced by recycling thought leader organizations (TLOs) in the United States. Using thematic analysis, this study analyzes publicly available recycling webpages from 99 TLOs, including state government agencies, state-level non-governmental organizations (NGOs), national and regional …

When Words Flow Like Water: How The Enbridge Line 3 Pipeline Environmental Impact Statement Failed To Prevent Hydrogeologic Harm In Minnesota, Carly Gutzmann

Journal of Earth and Life Science

For the aquifers of Minnesota, the environmental impact statement (EIS) was a promise of protection that never left the page. An environmental impact statement is meant to be an aid in the decision making process in order to ensure that projects consider potential environmental harms that may occur. However, they are often used instead as another regulatory box to check, rather than as active considerations when planning. As such, a project plan can be flawed from the start—if project developers only consider environmental impacts after they have already put considerable time, effort, and funding into their project as-is, they may …
