We conducted a Northern New England survey to understand the impacts of the COVID-19 pandemic on food security, food access, home food production, health behaviors, and health outcomes. The surveys were conducted in the spring of 2022 (April-May) with a total of 1,013 adults (598 in Maine and 415 in Vermont) responding to the survey. Key findings include:1. The prevalence of food insecurity remains similarly high to early points in the pandemic, likely driven by inflation and food prices, and long-term impacts from the pandemic. 2. The majority (62%) indicated the recent rise in food prices affected their food purchasing, …

Mitigating the spread of disease is crucial for the well-being of agricultural production systems. Implementing biosecurity disease prevention measures can be expensive, so producers must balance the costs of biosecurity investments with the expected benefits of reducing the risk of infections. To investigate the risk associated with this decision making process, we developed an online experimental game that simulates biosecurity investment allocation of a pork production facility during an outbreak. Participants are presented with several scenarios that vary the visibility of the disease status and biosecurity protection implemented at neighboring facilities. Certain rounds allowed participants to spend resources to reduce …

We conducted a Northern New England survey to understand the initial and continued impacts of the COVID-19 pandemic on food security, food access, and home food production (HFP) (i.e. gardening, fishing, harvesting shellfish, foraging, hunting, trapping, raising animals for meat, dairy, or eggs, and food preservation such as canning, drying or freezing). The surveys were conducted in the Spring and Summer of 2021 (March – June). The survey was conducted in Maine (n = 562) and Vermont (n = 426). The cohort of respondents was representative of racial and ethnic identities of Vermont and Maine state populations. The data presented …


Climate Impacts Associated With Reduced Diet Diversity In Children Across Nineteen Countries, Meredith T. Niles, Benjamin F. Emery, Serge Wiltshire, Molly E. Brown, Brendan Fisher, Taylor H. Ricketts Jan 2021

Climate Impacts Associated With Reduced Diet Diversity In Children Across Nineteen Countries, Meredith T. Niles, Benjamin F. Emery, Serge Wiltshire, Molly E. Brown, Brendan Fisher, Taylor H. Ricketts

College of Agriculture and Life Sciences Faculty Publications

It is widely anticipated that climate change will negatively affect both food security and diet diversity. Diet diversity is especially critical for children as it correlates with macro and micronutrient intake important for child development. Despite these anticipated links, little empirical evidence has demonstrated a relationship between diet diversity and climate change, especially across large datasets spanning multiple global regions and with more recent climate data. Here we use survey data from 19 countries and more than 107 000 children, coupled with 30 years of precipitation and temperature data, to explore the relationship of climate to child diet diversity while …

College of Engineering and Mathematical Sciences Faculty Publications

We introduce a qualitative, shape-based, timescale-independent time-domain transform used to extract local dynamics from sociotechnical time series—termed the Discrete Shocklet Transform (DST)—and an associated similarity search routine, the Shocklet Transform And Ranking (STAR) algorithm, that indicates time windows during which panels of time series display qualitatively-similar anomalous behavior. After distinguishing our algorithms from other methods used in anomaly detection and time series similarity search, such as the matrix profile, seasonal-hybrid ESD, and discrete wavelet transform-based procedures, we demonstrate the DST’s ability to identify mechanism-driven dynamics at a wide range of timescales and its relative insensitivity to functional parameterization. As an …

Chimera States And Seizures In A Mouse Neuronal Model, Henry M. Mitchell, Peter Sheridan Dodds, J. Matthew Mahoney, Christopher M. Danforth Oct 2020

Chimera States And Seizures In A Mouse Neuronal Model, Henry M. Mitchell, Peter Sheridan Dodds, J. Matthew Mahoney, Christopher M. Danforth

College of Engineering and Mathematical Sciences Faculty Publications

Chimera states - the coexistence of synchrony and asynchrony in a nonlocally-coupled network of identical oscillators - are often used as a model framework for epileptic seizures. Here, we explore the dynamics of chimera states in a network of modified Hindmarsh-Rose neurons, configured to reflect the graph of the mesoscale mouse connectome. Our model produces superficially epileptiform activity converging on persistent chimera states in a large region of a two-parameter space governing connections (a) between subcortices within a cortex and (b) between cortices. Our findings contribute to a growing body of literature suggesting mathematical models can qualitatively reproduce epileptic seizure …

Modeling The Influence Of Public Risk Perceptions On The Adoption Of Green Stormwater Infrastructure: An Application Of Bayesian Belief Networks Versus Logistic Regressions On A Statewide Survey Of Households In Vermont, Qing Ren, Asim Zia, Donna M. Rizzo, Nancy Mathews

College of Engineering and Mathematical Sciences Faculty Publications

There is growing environmental psychology and behavior literature with mixed empirical evidence about the influence of public risk perceptions on the adoption of environmentally friendly “green behaviors”. Adoption of stormwater green infrastructure on residential properties, while costlier in the short term compared to conventional greywater infrastructure, plays an important role in the reduction of nutrient loading from non-point sources into freshwater rivers and lakes. In this study, we use Bayesian Belief Networks (BBNs) to analyze a 2015 survey dataset (sample size = 472 respondents) about the adoption of green infrastructure (GSI) in Vermont’s residential areas, most of which are located …

Modeling Alternative Collaborative Governance Network Designs: An Agent-Based Model Of Water Governance In The Lake Champlain Basin, Vermont, Patrick Bitterman, Christopher J. Koliba

College of Agriculture and Life Sciences Faculty Publications

Published by Oxford University Press on behalf of the Public Management Research Association. With the widespread use of collaborative governance mechanisms for mitigating water pollution, an opportunity exists to test alternative institutional designs based on collaborative governance theory using computer simulation models, particularly when there is a clear relationship between governance networks, observable resource allocation decisions, and measurable outcomes. This is especially the case for wicked problems like nonpoint source water pollution where there are compelling questions regarding how best to design policies, allocate funds, and build administrative capacity to meet water quality standards. We present an agent-based model (ABM) …

Dynamical Climatic Model For Time To Flowering In Vigna Radiata, Konstantin Kozlov, Alena Sokolkova, Cheng Ruei Lee, Chau Ti Ting, Roland Schafleitner, Eric Bishop-Von Wettberg, Sergey Nuzhdin, Maria Samsonova

College of Agriculture and Life Sciences Faculty Publications

Background: Phenology data collected recently for about 300 accessions of Vigna radiata (mungbean) is an invaluable resource for investigation of impacts of climatic factors on plant development. Results: We developed a new mathematical model that describes the dynamic control of time to flowering by daily values of maximal and minimal temperature, precipitation, day length and solar radiation. We obtained model parameters by adaptation to the available experimental data. The models were validated by cross-validation and used to demonstrate that the phenology of adaptive traits, like flowering time, is strongly predicted not only by local environmental factors but also by plant …

There is broad agreement that current food systems are not on a sustainable trajectory that will enable us to reach the Sustainable Development Goals by 2030, particularly in the face of anthropogenic climate change. Guided by a consideration of some food system reconfigurations in the past, we outline an agenda of work around four action areas: rerouting old systems into new trajectories; reducing risks; minimising the environmental footprint of food systems; and realigning the enablers of change needed to make new food systems function. Here we highlight food systems levers that, along with activities within these four action areas, may …

We investigate phase transitions associated with three control methods for epidemics on small world networks. Motivated by the behavior of SARS-CoV-2, we construct a theoretical SIR model of a virus that exhibits presymptomatic, asymptomatic, and symptomatic stages in two possible pathways. Using agent-based simulations on small world networks, we observe phase transitions for epidemic spread related to: 1) Global social distancing with a fixed probability of …


Text Mining The Food Security Literature Reveals Substantial Spatial Bias And Thematic Broadening Over Time, Matthew W. Cooper, Molly E. Brown, Meredith T. Niles, Moataz M. Elqadi Sep 2020

Text Mining The Food Security Literature Reveals Substantial Spatial Bias And Thematic Broadening Over Time, Matthew W. Cooper, Molly E. Brown, Meredith T. Niles, Moataz M. Elqadi

College of Agriculture and Life Sciences Faculty Publications

We conducted text mining analyses on nearly the entirety of academic literature related to food security. Assessing the literature's spatial scope, we found a truly global body of research conducted across 187 different countries, but with significant spatial heterogeneities in where research is conducted. Comparing the spatial distribution of the literature to actual rates of food insecurity, we found only a slight association between where food security research is conducted and where food security needs are located. Using topic modeling to assess the thematic scope of the literature, we found that originally food security research focused on economic policy and …

Behavioral research on natural resource management has revealed a number of variables that can impact collective action. This research builds upon an interactive decision game using experimental economics methods with a focus on production decisions and the corresponding impact they have on ambient water quality. Using hierarchical clustering algorithms, four primary types of behavior are identified: competitive, hypercompetitive, cooperative, and hypercooperative. The results from the experiment are used to test the following three hypotheses: (1) financial incentives increase cooperative behavior, (2) increasing the number and frequency of water quality sensors increases cooperative behavior, and (3) the spatial location of the …

College of Engineering and Mathematical Sciences Faculty Publications

Chagas disease is a lethal, neglected tropical disease. Unfortunately, aggressive insecticide-spraying campaigns have not been able to eliminate domestic infestation of Triatoma dimidiata, the native vector in Guatemala. To target interventions toward houses most at risk of infestation, comprehensive socioeconomic and entomologic surveys were conducted in two towns in Jutiapa, Guatemala. Given the exhaustively large search space associated with combinations of risk factors, traditional statistics are limited in their ability to discover risk factor interactions. Two recently developed statistical evolutionary algorithms, specifically designed to accommodate risk factor interactions and heterogeneity, were applied to this large combinatorial search space and used …
