Noncooperative Dynamics In Election Interference, David Rushing Dewhurst, Christopher M. Danforth, Peter Sheridan Dodds

College of Engineering and Mathematical Sciences Faculty Publications

Foreign power interference in domestic elections is an existential threat to societies. Manifested through myriad methods from war to words, such interference is a timely example of strategic interaction between economic and political agents. We model this interaction between rational game players as a continuous-time differential game, constructing an analytical model of this competition with a variety of payoff structures. All-or-nothing attitudes by only one player regarding the outcome of the game lead to an arms race in which both countries spend increasing amounts on interference and counterinterference operations. We then confront our model with data pertaining to the Russian …

Upcycling Phosphorus Recovered From Anaerobically Digested Dairy Manure To Support Production Of Vegetables And Flowers, Katherine K. Porterfield, Robert Joblin, Deborah A. Neher, Michael Curtis, Steve Dvorak, Donna M. Rizzo, Joshua W. Faulkner, Eric D. Roy

Rubenstein School of Environment and Natural Resources Faculty Publications

Dissolved air flotation (DAF) separates phosphorus (P)-rich fine solids from anaerobically digested dairy manure, creating opportunities to export surplus P to the marketplace as a bagged plant food product. Seedlings of tomato and marigold were amended at various volume per volume (v/v) ratios with plant foods consisting of fine solids upcycled (i.e., transformed into a higher quality product) by drying and blending with other organic residuals. A plate competition assay was conducted to assess the fine solids' potential to suppress the plant pathogen Rhizoctonia solani. Plant foods were comprised of 2.0-2.1% N, 0.8-0.9% P and 0.6-0.8% K. Extractions indicated that …

Majority Of Rural Residents Compost Food Waste: Policy And Waste Management Implications For Rural Regions, Meredith T. Niles

College of Agriculture and Life Sciences Faculty Publications

A growing number of municipalities and states are implementing household food waste diversion efforts such as curbside compost programs, though these programs present challenges for participation and implementation. While many food waste diversion programs are occurring in densely populated regions, understanding food waste management in rural regions is less studied. This research examines the food waste perceptions and current and future food waste management behaviors of residents in Vermont, one of the most rural U.S. states, through a representative telephone survey of Vermont residents (n = 583) in 2018. The findings suggest 55% of residents support banning food waste from …

Agricultural Development Addresses Food Loss And Waste While Reducing Greenhouse Gas Emissions, Gillian L. Galford, Olivia Peña, Amanda K. Sullivan, Julie Nash, Noel Gurwick, Gillian Pirolli, Meryl Richards, Julianna White, Eva Wollenberg

Rubenstein School of Environment and Natural Resources Faculty Publications

Food loss and waste (FLW) reduce food available for consumption and increase the environmental burden of production. Reducing FLW increases agricultural and value-chain productivity and may reduce greenhouse gas emissions associated with feeding the global population. Although studies of interventions that reduce FLW exist, almost no research systematically investigates FLW interventions across multiple value chains or countries, most likely due to challenges in collecting and synthesizing data and estimates, let alone estimating greenhouse gas emissions. Our research team investigated changes in FLW in projects supported by the United States Agency for International Development's (USAID) global hunger and food security initiative, …

Are Wolves Welcome? Hunters' Attitudes Towards Wolves In Vermont, Usa, Nelson Grima, John Brainard, Brendan Fisher

Rubenstein School of Environment and Natural Resources Faculty Publications

Published by Cambridge University Press on behalf of Fauna & Flora International. The forests of the north-east USA were once home to the Wolf Canis lupus, a species that played an important role in the ecology of this region. However, wolves were eradicated from the region more than a century ago, altering the species composition of the landscape and driving cascading changes in this ecosystem. Outdoor recreation is a major component of the economy of this region, and outdoor recreationists, including the hunting community, have a strong influence over decision-making related to policies on natural resources. Given their powerful position, …

A Tandem Evolutionary Algorithm For Identifying Causal Rules From Complex Data, John P. Hanley, Donna M. Rizzo, Jeffrey S. Buzas, Margaret J. Eppstein

College of Engineering and Mathematical Sciences Faculty Publications

We propose a new evolutionary approach for discovering causal rules in complex classification problems from batch data. Key aspects include (a) the use of a hypergeometric probability mass function as a principled statistic for assessing fitness that quantifies the probability that the observed association between a given clause and target class is due to chance, taking into account the size of the dataset, the amount of missing data, and the distribution of outcome categories, (b) tandem age-layered evolutionary algorithms for evolving parsimonious archives of conjunctive clauses, and disjunctions of these conjunctions, each of which have probabilistically significant associations with outcome …

Fragmentation And Inefficiencies In Us Equity Markets: Evidence From The Dow 30, Brian F. Tivnan, David Rushing Dewhurst, Colin M. Van Oort, John H. Ring, Tyler J. Gray, Brendan F. Tivnan, Matthew T.K. Koehler, Matthew T. Mcmahon, David M. Slater, Jason G. Veneman, Christopher M. Danforth

College of Engineering and Mathematical Sciences Faculty Publications

Using the most comprehensive source of commercially available data on the US National Market System, we analyze all quotes and trades associated with Dow 30 stocks in calendar year 2016 from the vantage point of a single and fixed frame of reference. We find that inefficiencies created in part by the fragmentation of the equity marketplace are relatively common and persist for longer than what physical constraints may suggest. Information feeds reported different prices for the same equity more than 120 million times, with almost 64 million dislocation segments featuring meaningfully longer duration and higher magnitude. During this period, roughly …

Looking Into The Dragons Of Cultural Ecosystem Services, Rachelle K. Gould, Alison Adams, Luis Vivanco

Rubenstein School of Environment and Natural Resources Faculty Publications

Cultural ecosystem services research is in a somewhat tumultuous state. The cultural ecosystem services (CES) idea is seen simultaneously as a welcoming, expansive addition to conservation policy-making and as a strange, square-peg-in-a-round-hole concept that should be replaced by a more appropriate metaphor or conceptual structure. This confluence of interest and skepticism suggests an opportune moment to take stock of CES, both as a concept and growing scholarly field. Here, we focus on dilemmas that characterize and constitute CES as a field of empirical inquiry and practice. We describe five tensions that characterize the field (and mirror tensions in interdisciplinary work …

The Woods Around The Ivory Tower: A Systematic Review Examining The Value And Relevance Of School Forests In The United States, Kimberly J. Coleman, Elizabeth E. Perry, Dominik Thom, Tatiana M. Gladkikh, William S. Keeton, Peter W. Clark, Ralph E. Tursini, Kimberly F. Wallin

Rubenstein School of Environment and Natural Resources Faculty Publications

Throughout the United States, many institutions of higher education own forested tracts, often called school forests, which they use for teaching, research, and demonstration purposes. These school forests provide a range of benefits to the communities in which they are located. However, because administration is often decoupled from research and teaching, those benefits might not always be evident to the individuals who make decisions about the management and use of school forests, which may undervalue their services and put these areas at risk for sale, development, or over-harvesting to generate revenue. To understand what messages are being conveyed about the …

Room To Grow: Agritourism Opportunities In Vermont Agriculture And Food System Plan: 2020 (Part One), Carolyn Hricko, Katie Robertson, Nick Rose, Meredith T. Niles

Food Systems Master's Project Reports

This analysis demonstrates that there is signficant unrealized potential to advance agritourism within the Vermont Agriculture and Food System Plan: 2020 (Part One)1 strategic plan and that applying an agritourism lens allows for the identification of a wide range of additional opportunities that can support Vermont farmers and agritourism goals. While agritourism is recognized in the report with a dedicated issue brief, this subsector of Vermont agriculture is otherwise largely overlooked in the other opportunities identified in Vermont’s strategic plan, particularly for the agritourism activities of hospitality, recreation, and entertainment. While direct-to-consumer sales, agricultural education, and farm diversification were referenced …

College of Agriculture and Life Sciences Faculty Publications

Background: Lack of adherence with prescribed medications among the asthma populations exacerbates health outcomes and increases social and economic costs. Objectives: The proposed study aims to model patient-centric structural determinants of adherence rates among asthma patients and explore the potential of mobile health apps such as the TRUSTR platform to improve adherence using its power of monetary and non-monetary chatbotting and non-monetary nudges. Following specific hypotheses are tested: (1) Patient attributes, such as their age and medical condition, have significant effect on their adherence with the prescribed treatment plans. (2) Behavioral nudging with rewards and engagement via mobile health apps …

Narrative Medicine: Perspectives On Opioid Maintenance, Noorin Damji

Family Medicine Clerkship Student Projects

People who experience opioid addiction often feel marginalized by healthcare workers, or stigmatized by the medical system. Additionally, there are not enough medical providers to meet the needs of people who struggle with opioid addiction. These factors create barriers that prevent the medical establishment from effectively meeting the needs of people who experience addiction. This project compiles rich perspectives of patients on opioid maintenance treatment to share with medical students and providers to foster greater empathy for these patients, and positive attitudes toward managing substance use disorder among future medical providers.

Water Use Governance In A Temperate Region: Implications For Agricultural Climate Change Adaptation In The Northeastern United States, Rachel E. Schattman, Meredith T. Niles, Hannah M. Aitken

College of Agriculture and Life Sciences Faculty Publications

Climate change and access to water are interrelated concerns for agriculture and other sectors, even in temperate regions. Governance approaches and regulatory frameworks determine who has access to water, for what purpose, and when. In the northeastern United States, water governance has historically been conducted by states through a combination of statutory guidance and common law. However, it is unclear what effect if current governance approaches will be sufficient for achieving resource conservation and equitable allocation in a changing climate. To provide insight into these issues, we conducted the first review of freshwater governance in the 12 states that comprise …

Why We Publish Where We Do: Faculty Publishing Values And Their Relationship To Review, Promotion And Tenure Expectations, Meredith T. Niles, Lesley A. Schimanski, Erin C. Mckiernan, Juan Pablo Alperin

College of Agriculture and Life Sciences Faculty Publications

Using an online survey of academics at 55 randomly selected institutions across the US and Canada, we explore priorities for publishing decisions and their perceived importance within review, promotion, and tenure (RPT). We find that respondents most value journal readership, while they believe their peers most value prestige and related metrics such as impact factor when submitting their work for publication. Respondents indicated that total number of publications, number of publications per year, and journal name recognition were the most valued factors in RPT. Older and tenured respondents (most likely to serve on RPT committees) were less likely to value …

Open Knowledge Commons Versus Privatized Gain In A Fractured Information Ecology: Lessons From Covid-19 For The Future Of Sustainability, Martin Hensher, Katie Kish, Joshua Farley, Stephen Quilley, Katharine Zywert

College of Agriculture and Life Sciences Faculty Publications

COVID-19 has shone a bright light on a number of failings and weaknesses in how current economic models handle information and knowledge. Some of these are familiar issues that have long been understood but not acted upon effectively – for example, the danger that current systems of intellectual property and patent protection are actually inimical to delivering a cost-effective vaccine available to all, whereas treating knowledge as a commons and a public good is much more likely to deliver efficient outcomes for the entire global population. But COVID-19 has also demonstrated that traditional models of knowledge production and dissemination are …

Using Experimental Gaming Simulations To Elicit Risk Mitigation Behavioral Strategies For Agricultural Disease Management, Eric M. Clark, Scott C. Merrill, Luke Trinity, Gabriela Bucini, Nicholas Cheney, Ollin Langle-Chimal, Trisha Shrum, Christopher Koliba, Asim Zia, Julia M. Smith

College of Agriculture and Life Sciences Faculty Publications

Failing to mitigate propagation of disease spread can result in dire economic consequences for agricultural networks. Pathogens like Porcine Epidemic Diarrhea virus, can quickly spread among producers. Biosecurity is designed to prevent infection transmission. When considering biosecurity investments, management must balance the cost of protection versus the consequences of contracting an infection. Thus, an examination of the decision making processes associated with investment in biosecurity is important for enhancing system wide biosecurity. Data gathered from experimental gaming simulations can provide insights into behavioral strategies and inform the development of decision support systems. We created an online digital experiment to simulate …

Aridity In The Literature Of The American West: Water In Stegner's Angle Of Repose And Abbey's The Monkey Wrench Gang, Annie Frodeman

Graduate College Dissertations and Theses

This thesis examines how Wallace Stegner’s Angle of Repose and Edward Abbey’s The Monkey Wrench Gang have been molded by water scarcity and in turn have shaped the discourse about water. Angle of Repose offers a reliable history of water in the West, showing how the myth of the garden permeated the lives of people who made the journey West at the end of the nineteenth century. Stegner’s narrative of the building of the West shows what comes of humanity’s desire to change the environment by making the desert bloom. The Monkey Wrench Gang complements Stegner’s Angle of Repose as …

Quantifying The Health Benefits Of Nature Contact In Cities Across The Us, Aaron J. Schwartz

Graduate College Dissertations and Theses

Urbanization, the rise of sedentary lifestyles, and increasing screen time have led to a significant decline in nature contact, or how much time people spend in greenspace. At the same time, urban populations are experiencing declining physical and mental well-being. While nature contact has been shown to have a variety of health benefits, these benefits have not been well-quantified or verified across different geographic contexts. In addition, there is a lack of clarity around how the benefits of nature contact vary temporally (e.g. seasonally) and between different types of greenspaces. In this dissertation, I investigate the health benefits of urban …

Seed Systems Of Bhutanese-Nepali Refugee Gardeners: Making Place In Chittenden County, Vermont, June Guo

Graduate College Dissertations and Theses

War, political unrest, and climate disasters cause major disruptions to peoples’ lives and livelihoods, and for subsistence farmers, who make up much of the world’s population, this means their agricultural practices. Among the farming habits that are disrupted are seed systems, defined in this study as the market and nonmarket institutions that affect how farmers access, store, share, distribute, and learn about propagative materials. In particular, the local varieties and knowledge, also described as Traditional Ecological Knowledge, contained in farmer-managed informal seed systems may be vulnerable when a crisis disrupts the social ties that the seed systems are built upon. …
