Net Zero And Settler Futurity, Jesse Goldstein

Sociology Publications

Net Zero ideology promises that current and ongoing emissions can be partially offset by ‘negative emissions’ strategies such as carbon capture and sequestration, allowing carbon intensive firms to narrate themselves as agents that are solving – not causing – the climate crisis. This represents a shift in liberal and corporate environmentalism away from both denial and delay, towards a new strategy acknowledging the need to end fossil fuel use while urgently deferring transformations to a future made possible by not-yet developed technological innovations. This paper argues that a through-line of settler futurity provides affective infrastructure potent enough to transect opposing …

Measuring Nature’S Contributions To People Provided By Species In The Gulf Of Maine Rocky Intertidal Ecosystem, Madelyn L. Eippert

Honors Theses

Ecosystem services aim to quantify the value of nature provided to humans. However, Ecosystem services are typically measured at the level of the ecosystem as a whole and do not consider interactions between species in an ecosystem. Ultimately, the species in an ecosystem determine the services that are provided. Measuring ecosystem services at the landscape level misses the complex interactions and changing biodiversity of ecosystems. Currently, there is no accepted framework to link ecosystem services to species. In this thesis, I developed a framework to link Nature’s Contributions to People (NCP) to species. NCP includes 18 specific contributions (i.e. 18 …

Quantifying Wastewater Contributions To The Upper Clark Fork River, Claire Utzman

Graduate Student Theses, Dissertations, & Professional Papers

Though algae are at the base of food webs in many rivers, large algal blooms are increasing in frequency and can cause problems with nutrient cycling, depletion of oxygen supplies at night, and release of toxic chemicals. One leading cause of algal blooms is nutrient loading into rivers, and controlling nutrient release in wastewater is one approach that can help limit algal growth. To reduce the intensity of algal blooms in the Clark Fork River in western Montana, numeric nutrient standards were put in place that regulated the release of the nutrients nitrogen and phosphorus into the river from wastewater. …

Coalescence: A Carnivore Coexistence Curriculum That Braids Indigenous & Western Ecological Knowledge Into A Relevant And Experiential Learning Opportunity For Youth, Stephanie Anne Barron

Graduate Student Theses, Dissertations, & Professional Papers

As grizzly bears (Ursus arctos horriblis) begin to reoccupy more of their historic range, and as humans and large carnivore populations continue to increase, incidences of human carnivore conflict are on the rise. A decolonial curriculum designed in collaboration with the Confederated Salish and Kootenai Tribe’s wildlife biologists stands to increase awareness of Indigenous ecological knowledge and teach youth about the importance of coexistence with carnivores. Additionally, this project could greatly influence youth perceptions of grizzly bears and other large carnivores. This research project examines the development and implementation of a carnivore coexistence curriculum for youth that is guided by …

Quantifying Structural Vegetation Change On Arctic Tundra: A Multi-Decadal Study Integrating Remotely Sensed Imagery And Traditional Field Measurements, Anna M. Moser

Graduate Student Theses, Dissertations, & Professional Papers

Arctic regions have experienced an amplified rate of climate warming in recent decades, contributing to well-documented increases in tundra vegetation productivity. Satellite remote sensing has historically played a crucial role in detecting and quantifying trends at regional and biome scales; however, coarse resolution imagery has proven insufficient for capturing fine-scale variability in vegetation response. Considering the spatial heterogeneity of tundra vegetation, high resolution, plot-scale remote sensing observations are necessary. This study couples traditional field measurements with high-resolution unmanned aerial vehicle (UAV) imagery and plane-based aerial photos to quantify changes in vegetation on the North Slope of Alaska over a 28-year …

Mind, Body, And Farmland: The Agricultural Revolution Of Regenerative Agriculture And The Social Construction Of Sustainability., Amanda C. Pennett

Honors Theses

An agricultural revolution has begun to take place in light of the growing awareness of environmental issues that impact crop production on farms. In the beginning of the fall of 2022, I began to study the culture of regenerative agriculture in rural Pennsylvania using anthropological methods, including participant-observation and semi-structured interviews, working alongside local farmers. I was also interested in uncovering the flaws in our current industrial agricultural system and how farming could be reimagined to benefit farmers’ mental health, soils, and ecosystems while privileging the voices of those farmers committed to regenerative farming. The ongoing evolution of regenerative farming …

Due to the dynamic nature of the construction industry and the involvement of multiple parties with diverse goals, knowledge, and skills, the industry is susceptible to various risks that can undermine the sustainability of projects. This research aims to develop a Lean Management (LM) framework to deliver sustainable construction projects through reducing risks during the design process. …

Incomplete Streets, Michael Lewyn

Scholarly Works

Over 1700 complete streets policies have been adopted by state and local government; these policies typically provide that streets shall be designed to benefit all users, not just motorists. This article analyzes some complete streets policies, and concludes that even above-average policies are often too vague and underfunded to significantly change the status quo. The article suggests a variety of reforms that might make complete streets policies more effective.

From The Ground Up: A Complex Systems Approach To Climate Change Adaptation In Agriculture, Karen Buchsbaum

Antioch University Dissertations & Theses

Climate change presents an unprecedented challenge to global agriculture and food security. Small farms are especially vulnerable to the local impacts of large-scale drivers of change. Effective adaptation in agriculture requires working across scales, and geographic, political, and disciplinary boundaries to address barriers. I use elements of case study, agent-based modeling and serious games, to design a model of farmer decision-making using the sociocognitive framework of climate change adaptation. I examine how adaptation functions as a process, how complex dynamics influence farmer behavior, and how individual decisions influence collective behavior in response to climate change. This novel approach to adaptation …

Late Holocene Fire History Reconstruction Of Beaver Lake In The Northwest Lowlands Of The Olympic Peninsula, Grace Mckenney

All Master's Theses

Fire is an essential component of the landscapes and forests of the Pacific Northwest, including the temperate rainforests of the Olympic Peninsula. Previous fire history reconstructions from the peninsula show that fire return intervals varied throughout the postglacial period, primarily in response to climatic changes and corresponding shifts in vegetation. However, much less is known about the fire history of the low-elevation forests of the Olympic Peninsula and the role of cultural fire regimes in these environments. The purpose of this study was to reconstruct the paleoenvironmental history of a low-elevation study site, Beaver Lake, located in the northwestern part …

Five Considerations For Twenty-First Century Climate Policy, Matthew G. Burgess

FIU Law Review

As the twenty-first century advances, society is entering a new phase regarding climate change. Impacts of climate change are becoming more salient in the present, rather than being only far-off in the future. Progress on flattening—and in many affluent countries, reducing—greenhouse gas emissions is also becoming salient, though the progress underperforms international targets. Slowing economic growth and major technological and geopolitical disruptions are creating new challenges and uncertainties. One of these challenges is a political climate of deep divisions and rising distrust in fact-finding institutions—a climate that is ripe for demagoguery. In the United States and some other countries, the …

Urban Streetscape Changes In Portland, Oregon: A Longitudinal Virtual Audit, Tomoya Hanibuchi, David Banis, Hunter Shobe, Tomoki Nakaya, Shohei Nagata

Geography Faculty Publications and Presentations

Streetscape imagery has considerable potential for observing urban change. The literature lacks sufficient longitudinal studies, however, on urban change considering human perception and activities. We conducted a longitudinal virtual audit to observe the change in urban liveliness, human activities, and built environment by examining streetscape imagery taken in the late 2000s and the late 2010s in Portland, Oregon. Eleven untrained crowd workers were recruited to provide liveliness ratings of 24,242 streetscape images for both periods. Tabulation, mapping, and multilevel regression analyses were conducted to observe the distribution, changes in liveliness, and the factors affecting these changes. The results confirmed that …

Probing The Anoxic World Of Coastal Marine Sediments In New England: Understanding The Novel Partnership Between Protists And Their Bacterial Symbionts, Raúl A. Gutiérrez

Open Access Master's Theses

In the oxygen-depleted environments of New England's coastal marine sediment, microbial communities engage in symbiotic interactions to overcome energy deficiencies from oxygen limitation. Among these interactions, ciliates, known for their ability to form diverse symbiotic relationships, play a prominent role. The ciliated protozoa, Metopus sp. commonly form symbiotic relationships with bacteria and archaea that support their fermentative metabolism (Fenchel and Finlay, 1995), though the diversity of these partnerships, particularly in the ocean, is poorly known. To gain insights into the interactions between Metopus ciliate cultures and their microbial partners, we employed Fluorescence in Situ Hybridization (FISH) with species-specific probes. We …

Exploring The Links Between Unknowns, Uncertainty And Epistemological Understanding In A More Authentic Form Of School Science Investigation, Matthew Wharf

Other Faculty of Arts, Humanities and Business Theses

This research explored the role a more ‘authentic’ science investigation had on the epistemological understanding of secondary school students. It reviewed the understanding of what is taught within the science curriculum in terms of epistemology and the Nature of Science (NOS) and what may be considered a more authentic activity that more closely aligns with the qualities of professional science, where new knowledge is being formed as compared to what could be seen as conventional science investigations, the repetition of classic experiments. Lessons of 3 different classes, at different schools and in different years were used. An investigation lesson from …

Gender Roles In Natural Resource Use In Madagascar, Sarahana Shrestha, Cortni Borgerson, Be Jean Rodolph Rasolofoniaina

Department of Anthropology Faculty Scholarship and Creative Works

Understanding gender roles in natural resource use is essential for culturally-tailored effective conservation. Despite its conservation priority, little is known about the gender roles of forest product use in Madagascar. This study used over seven years of data from 1,255 interviews on the extraction, use, and sale of forest, freshwater, and marine resources, to examine gender roles. We found that gender significantly affects natural resource use in Madagascar. While men were primarily responsible for natural resource collection, women collected nearly all resources in at least one household. Both genders collected resources, with subsistence use as the primary incentive for resource …

Teachers’ Perceptions Of Formative Assessment For Students With Disability: A Case Study From India, Anannya Chakraborty, Amit Kaushik

Assessment and Reporting

India has made significant progress in improving the enrolment of students with disability but still has a long way to go before schools can be called inclusive. Despite the widely acknowledged relevance of assessments in shaping teaching and learning practices, little research has been done in disability-inclusive assessment in the Indian setting. In this paper, we explore teachers’ perceptions of disability inclusion in formative assessments, including the use of various kinds of accommodations and adaptations, factors that affect the implementation of disability-inclusive formative assessments, and challenges. It is argued that teacher professional development and teacher–parent partnerships are essential for ensuring …
