Community Science And Coyote Stories: Capturing And Communicating Nature's Non-Material Values For Use In Decision-Making, Joshua Wright Morse

Graduate College Dissertations and Theses

The reasons and ways that nature matters underlie every part of environmental decision-making. Yet, there are disparities in how different kinds of benefits from and values about nature are represented in policy and practice. This dissertation explores how decision-makers and community members value nature broadly and also in the context of a specific human-wildlife interaction in Vermont, United States.

In my first chapter, I conduct semi-structured interviews with environmental sector practitioners in Vermont to learn about their awareness of non-material values from nature. I find that practitioners talk readily about both material and non-material ecosystem services as well as multiple …

Unraveling Public Evacuation Likelihood: Structural Equation Models And The Extended Parallel Process Model In Focus, Molly Margaret Myers

Graduate College Dissertations and Theses

This study explores the intricate relationships between risk perception, efficacy appraisal, and evacuation likelihood in the context of flooding among the United States public. The Extended Parallel Process Model (EPPM) developed by Witte (1992) serves as the theoretical framework for this study, emphasizing the two-pronged appraisal process of threat and efficacy, influencing individual responses to risk messaging. Analysis of the data delves into the relationships between risk perception and evacuation likelihood, offering insights into the public's understanding of flood risk and readiness for impending flood events. This study used Structural Equation Modeling (SEM) to discern the impact of threat and …

How To Analyze Parental Conversation Online: A Computational Stack For Studying Vaccine Hesitancy., Carter Willets Ward

Graduate College Dissertations and Theses

Despite national and international organizations such as the CDC and WHO recognizing the value of vaccines and their importance in addressing public health concerns, there has been a decline in coverage for even the most established vaccines over the past three years. The global COVID-19 pandemic has contributed to this decline via decreases in medical resource accessibility and an increase in vaccine hesitancy. Even before the COVID-19 pandemic, WHO had recognized vaccine hesitancy as one of the top ten threats to public health. In the present work, we introduce a background account of (1) vaccine hesitancy and (2) anti-vax activism, …

Imaginaries Of The Great Outdoors: Comparing Facebook Postings Across Resource Places, Frances Hoag

Graduate College Dissertations and Theses

Communication across agencies, interested audiences, and the public is central to resource management. While social media expands agencies’ communication options, it also may present opportunities for constructing and presenting “imaginaries” – collectively imagined discourses that that shape understandings of place and influence the world views of followers. Imaginaries are “socially constructed, taken-for-granted meanings about reality that make everyday social and cultural practices seem obvious and sensible to people” (Stokowski et al., 2021). Extending prior research, we sought to understand whether/how resource management agencies used social media to construct and deploy imaginaries. Data were collected during 2021-2022 from resource management agencies …

Multi-Scale Assessment Of Gully Erosion At Road Drainage Outlets, Emma Louise Estabrook

Graduate College Dissertations and Theses

Gully erosion and sediment deposition from roads are underrated sources of sediments entering receiving waterways. While gully erosion has been studied throughout the world, the monitoring of the temporal and spatial erosional processes related to culverts and road drainage is rare. The objectives of this study are to quantify rates of gully erosion from Vermont’s transportation drainage networks at multiple temporal scales and report on insights gained from a multi-scale approach to monitoring gully erosion. To quantify event to seasonal timescales of gully erosion, high resolution terrestrial LiDAR surveys were conducted at 13 field sites. Field sites were monitored at …

Master’S Project: Exploring And Supporting Social And Ecological Dimensions Of Pollinator Habitat Enhancement In Burlington, Vt, Victoria Hellwig

Rubenstein School Masters Project Publications

Urbanization and other manmade impacts threaten critical pollinator species like the bumblebee, whose populations are significantly affected by habitat loss. In response, activists in the City of Burlington are enhancing habitat to increase biodiversity through collaborative partnerships in urban green spaces. In an effort to explore and support pollinator habitat enhancement in Burlington, I examined social interactions involved in a group highly motivated to enhance habitat at Lakeview Cemetery and Champlain Elementary School, with an emphasis on power dynamics and place meanings of these sites. In conjunction with this exploration, I created landscape designs, planted a native habitat garden, and …

An International Pilot Study Of Volunteer Stream Monitoring Groups: The Role Of Place Attachment In Volunteer Motivations, Rachel Pierson

Graduate College Dissertations and Theses

Engaging the public in scientific research through volunteer monitoring (a form of community science) has potential to expand knowledge of conditions and to improve collaborative decision-making. Many studies have sought to understand motivations for participation and potential resulting actions or behaviors that benefit the environment. Place-based connections have been demonstrated to lead people to adopt environmentally responsible behaviors. However, few studies have considered possible differences in motivations across countries or the role place attachment may play as a driver of initial or sustained participation.

The aim of this research was to determine the extent to which place attachment influences people’s …

Enhancing Ecosystem Services And Climate Resilience In Agriculture: A Transdisciplinary Approach, Alissa White

Graduate College Dissertations and Theses

A complex of social, economic and environmental factors influences agricultural management in the northeastern US. Farmers often balance goals of farm viability, environmental stewardship, and resilience to climate change, while also under public pressure to enhance the provisioning of ecosystem services from their landscapes. Changes in farm management have been identified as cost-effective ways to address both local water quality issues, and global anthropogenic influences on greenhouse gas concentrations. Individual decision-making on the part of farmers that determines the fate of ecosystem service provisioning from agroecosystems, placing increasing importance on understanding how policy, outreach and research can support farmers’ capacity …

After The Flood: Exploring The Influence Of Risk Perception And Decision Criteria Preference On Flood Mitigation In The Lake Champlain Richelieu River Basin, Emma Jane Spett

Graduate College Dissertations and Theses

In April of 2011, heavy rainfall paired with snow melt from the Green and Adirondack Mountains caused unprecedented flooding in the Lake Champlain Richelieu River (LCRR) basin. A study was subsequently convened by the International Joint Commission (IJC), and was tasked with identifying how flood forecasting, preparedness, and mitigation could be improved in order to reduce the impact of flooding in this transboundary watershed, and build the greater community’s resilience to flooding. A component of this study includes an assessment of the social acceptability and political feasibility of potential flood mitigation measures, which was in part carried out through the …

Quantifying Language Changes Surrounding Mental Health On Twitter, Anne Marie Stupinski

Graduate College Dissertations and Theses

Mental health challenges are thought to afflict around 10% of the global population each year, with many going untreated due to stigma and limited access to services. Here, we explore trends in words and phrases related to mental health through a collection of 1- , 2-, and 3-grams parsed from a data stream of roughly 10% of all English tweets since 2012. We examine temporal dynamics of mental health language, finding that the popularity of the phrase ‘mental health’ increased by nearly two orders of magnitude between 2012 and 2018. We observe that mentions of ‘mental health’ spike annually and …

Quantifying Proverb Dynamics In Books, News Articles, And Tweets, Ethan Davis

Graduate College Dissertations and Theses

Proverbs are an essential component of language and culture, and though much attention has been paid to their history and currency, there has been comparatively little quantitative work on the frequency with which they are used, and the dynamics of their use over time. With wider availability of large corpora reflecting many diverse genres of documents, it is now possible to take a wider view of the importance of the proverb. Can a corpus linguistic approach to phraseology support existing histories, and what further insight can be gained from a quantitative approach? This study measures temporal changes in the relevance …

Policy And Economic Variables Influencing Adoption Of Sustainable Electrification In Rural Sub-Saharan Africa, Payne William Morgan

Graduate College Dissertations and Theses

Limited access to electricity remains a primary constraint to economic growth and the improvement of livelihoods throughout sub-Saharan Africa. In rural areas, electricity access is especially sparse. The reasons for the scarcity of electricity supply in the region are well documented, with low population density, limited household incomes, and poor regulatory institutions compounding to often make the investment of expanding electricity access result in poor or risky economic returns. However, the declining cost of solar PV and mandates for clean energy development throughout the region have created new channels for bringing electricity supply in potentially more cost-effective ways.Despite these macro …

Exploring Hidden Networks Yields Important Insights In Disparate Fields Of Study, Laurence Clarfeld

Graduate College Dissertations and Theses

Network science captures a broad range of problems related to things (nodes) and relationships between them (edges). This dissertation explores real-world network problems in disparate domain applications where exploring less obvious "hidden networks" reveals important dynamics of the original network.

The power grid is an explicit network of buses (e.g., generators) connected by branches (e.g., transmission lines). In rare cases, if k branches (a k-set) fail simultaneously, a cascading blackout may ensue; we refer to such k-sets as "defective". We calculate system risk of cascading failure due to defective 2-sets and 3-sets in synthetic test cases of the Polish and …

The Feasibility Of Over-Summer Snow Storage At The Craftsbury Outdoor Center, Craftsbury Vt, Hannah Sarah Weiss

Graduate College Dissertations and Theses

Climate change increases the unpredictability of winter weather and threatens the future of nordic skiing. Ski centers at high elevation and high latitude have employed over-summer snow storage, a climate change adaptation strategy, to ensure a consistent start-date to their winter ski season. Over-summer snow storage involves making a large pile of snow during winter and storing the snow beneath protective layers, such as wood chips or foam panels, to impede melt throughout the summer and fall. When ready to open the ski season, the ski center uncovers the pile and spreads the snow to create trails. Though many nordic …

The Food-Energy-Water Nexus, Embodied Injustices, And Transboundary Sustainability, Sonya Ahamed

Graduate College Dissertations and Theses

Intersections of food, energy, and water systems (the FEW nexus) pose many sustainability and governance challenges, including risks to ecosystems, inequitable distribution of benefits and harms across populations, and reliance on distant sources for food, energy, and water. Nexus-based approaches can offer more holistic pathways for societal transitions to FEW systems that are just and sustainable, but tend to focus narrowly on inputs (e.g. water ‘for’ energy) in ways that do little to address the historical roots and structural underpinnings of current system inadequacies, thus risking their perpetuation.

This dissertation widens the FEW nexus in two contexts in which the …

From Tap To Table: Consumer Values, Producer Attitudes, And Vermont Maple Syrup In A Dynamic Landscape, Aidan Conor Mccracken

Graduate College Dissertations and Theses

Harvesting the sap of maple trees [Acer saccharum] for use in the production of syrups and sugars has a storied history stretching back to the pre-Columbian practices of North America’s indigenous peoples. Since its adaptation by European settlers in the late seventeenth century and into the present day, the production of maple syrup has become especially integral to the livelihoods and cultural identities of farmers in Vermont. While oftentimes esteemed as a timeless agrarian tradition, market forces and environmental changes have led maple syrup producers (or sugarmakers) to adopt new production practices that scarcely resemble the taps, buckets, and draft …

Essays On Modeling And Analysis Of Dynamic Sociotechnical Systems, David Rushing Dewhurst

Graduate College Dissertations and Theses

A sociotechnical system is a collection of humans and algorithms that interact under the partial supervision of a decentralized controller. These systems often display in- tricate dynamics and can be characterized by their unique emergent behavior. In this work, we describe, analyze, and model aspects of three distinct classes of sociotech- nical systems: financial markets, social media platforms, and elections. Though our work is diverse in subject matter content, it is unified though the study of evolution- and adaptation-driven change in social systems and the development of methods used to infer this change.

We first analyze evolutionary financial market microstructure …

Measuring And Modeling Information Flow On Social Networks, Tyson Charles Pond

Graduate College Dissertations and Theses

With the rise of social media, researchers have become increasingly interested in understanding how individuals inform, influence, and interact with others in their social network and how the network mediates the flow of information. Previous research on information flow has primarily used models of contagion to study the adoption of a technology, propagation of purchase recommendations, or virality of online activity. Social (or "complex") contagions spread differently than biological ("simple") contagions. A limitation when researchers validate contagion models is that they neglect much of the massive amounts of data now available through online social networks. Here we model a recently …

Who Performs Pro-Environmental Behaviors (Pebs) And Why? Examining The Impacts Of Motivation, Environmental Attitudes, Identity, And Climate Change Concerns On Intended And Actual Pebs, Roberta Sofia Molokandov

Graduate College Dissertations and Theses

In 2018, the Intergovernmental Panel on Climate Change (IPCC) warned that the world only has until 2030 to prevent global temperatures from rising an additional .5 degrees Celsius from greenhouse gas emissions to thwart the catastrophic damage that could follow such warming. To reduce the concentration of greenhouse gasses in the atmosphere and alleviate human pressure on the natural environment, collective action must occur across the globe by consumers and producers. However, not everyone feels concerned about climate change, identifies as an environmentalist, or believes they can make an impact and that it is their responsibility to do so. Environmental …

Master’S Project: Vermont Town Forest Recreation Planning And Community Assistance Program: The Future Of Forest-Based Outdoor Recreation, Taylor M. Luneau

Rubenstein School Masters Project Publications

The Vermont Town Forest Recreation Planning Community Assistance Program (VTFRP) was a comprehensive community planning process held in ten diverse towns across Vermont. Led by the Urban and Community Forestry Program and the SE Group, the VTFRP helped towns develop a vision for the future management of their forests through open house workshops, site visits, steering committee meetings, and community surveys. The process provided towns with a forest recreation planning toolkit and an individualized action-based forest stewardship and recreation plan. By analyzing data from the community surveys and open house activities across all ten towns, my project considered the recreation …

Modeling Electric Vehicle Energy Demand And Regional Electricity Generation Dispatch For New England And New York, Sarah E. Howerter

Graduate College Dissertations and Theses

The transportation sector is a largest emitter of greenhouse gases in the U.S., accounting for 28.6% of all 2016 emissions, the majority of which come from the passenger vehicle fleet [1,2]. One major technology that is being investigated by researchers, planners, and policy makers to help lower the emissions from the transportation sector is the plug-in electric vehicle (PEV). The focus of this work is to investigate and model the impacts of increased levels of PEVs on the regional electric power grid and on the net change in CO2 emissions due to the decrease tailpipe emissions and the increase in …

Measuring Linguistic And Cultural Evolution Using Books And Tweets, Tyler Gray

Graduate College Dissertations and Theses

Written language provides a snapshot of linguistic, cultural, and current events information for a given time period. Aggregating these snapshots by studying many texts over time reveals trends in the evolution of language, culture, and society. The ever-increasing amount of electronic text, both from the digitization of books and other paper documents to the increasing frequency with which electronic text is used as a means of communication, has given us an unprecedented opportunity to study these trends. In this dissertation, we use hundreds of thousands of books spanning two centuries scanned by Google, and over 100 billion messages, or ‘tweets’, …

An Analysis Of Energy Transitions At Different Scales: Fossil Fuel Divestment In Higher Education And Individual Behavior, Elizabeth Palchak

Graduate College Dissertations and Theses

A sociotechnical energy transition requires both a shift to new technologies and attention to social issues like political movements, policy and human behavior. This dissertation investigates social elements of the renewable energy transition occurring at different scales. The core research questions are: How are universities creating and responding to the shifting language of fossil fuel investments? How and for whom do behavioral interventions work? And finally, do in-home displays (IHDs) change behaviors and attitudes of millennial energy users?

The three studies covered here occurred within higher education and reflect the importance of colleges and universities as dynamic players in energy …

Applications In Sentiment Analysis And Machine Learning For Identifying Public Health Variables Across Social Media, Eric Michael Clark

Graduate College Dissertations and Theses

Twitter, a popular social media outlet, has evolved into a vast source of linguistic data, rich with opinion, sentiment, and discussion. We mined data from several public Twitter endpoints to identify content relevant to healthcare providers and public health regulatory professionals. We began by compiling content related to electronic nicotine delivery systems (or e-cigarettes) as these had become popular alternatives to tobacco products. There was an apparent need to remove high frequency tweeting entities, called bots, that would spam messages, advertisements, and fabricate testimonials. Algorithms were constructed using natural language processing and machine learning to sift human responses from automated …

Increasing Private Contributions To Environmental Goods With Behavioral Insights, Hilary Byerly Flint

Graduate College Dissertations and Theses

Privately owned lands often undersupply environmental benefits and oversupply environmental costs through land use and management decisions. Insights into human behavior suggest a range of cognitive biases and nonstandard preferences that offer alternative explanations for and, perhaps, strategies to influence landowner behavior. People respond to simple changes in context and framing, make inconsistent choices over time, and respond to social influence—the opinions and behavior of peers.

This dissertation applies insights from behavioral science to strategies that seek to influence individual decisions that impact the environment, especially related to land management. First, I review existing experimental research on behavioral insights to …

Governing Water Quality Limits In Agricultural Watersheds, Courtney Ryder Hammond Wagner

Graduate College Dissertations and Theses

The diffuse runoff of agricultural nutrients, also called agricultural nonpoint source pollution (NPS), is a widespread threat to freshwater resources. Despite decades of research into the processes of eutrophication and agricultural nutrient management, social, economic, and political barriers have slowed progress towards improving water quality. A critical challenge to managing agricultural NPS pollution is motivating landowners to act against their individual farm production incentives in response to distant ecological impacts. The complexity of governing the social-ecological system requires improved understanding of how policy shapes farmer behavior to improve the state of water quality. This dissertation contributes both theoretically and empirically …

Some Results On A Class Of Functional Optimization Problems, David Rushing Dewhurst

Graduate College Dissertations and Theses

We first describe a general class of optimization problems that describe many natu- ral, economic, and statistical phenomena. After noting the existence of a conserved quantity in a transformed coordinate system, we outline several instances of these problems in statistical physics, facility allocation, and machine learning. A dynamic description and statement of a partial inverse problem follow. When attempting to optimize the state of a system governed by the generalized equipartitioning princi- ple, it is vital to understand the nature of the governing probability distribution. We show that optimiziation for the incorrect probability distribution can have catas- trophic results, e.g., …
