NSF EAGER: Risk Objects In Public Health Crisis: An Exploratory Investigation Of Stigma, Role-Triage, And Cautionary Measures

DURATION: October 1, 2015 – August 31, 2019
RESEARCHERS: James Kendra, Tricia Wachtendorf
ADDITIONAL INVESTIGATOR: Sarah Sisco, New York City Department of Health and Mental Hygiene

PROJECT DESCRIPTION:
DRC, in partnership with the New York City Department of Health and Mental Hygiene will conduct research on the management of the Ebola crisis in NYC. This study focuses on the generation of stigma in epidemic (or epidemic threatened) environments. In particular, we explore who is involved in the generation of stigma labels, why these labels emerge, the consequences they generate, and how various stakeholders promote, resist, or contend with stigma. The project seeks to learn how public officials, in an environment of scientific uncertainty and multijurisdictional conflict and contradiction, can counter stigmatization and mitigate the creation of risk.

NSF HAZARD SEES TYPE 2: Next Generation, Resilient Warning Systems For Tornados And Flash Floods

RESEARCHERS: Joseph Trainor
ADDITIONAL INVESTIGATOR: Brenda Philips, Umass Amherst)

FUNDING: National Science Foundation

PROJECT DESCRIPTION:
On this project, researchers are working as part of a collaborative, multi-disciplinary team to explore the basic science to support the next generation of warning systems for rapid-onset hazards such as tornadoes and flash floods.  In particular, we are working to better understand how to predict and disseminate warnings in shorter time windows and with smaller warning spaces.  In order to do this, the project combines new radar and mobile phone technology with an improved understanding of human responses to warnings in order to better meet the goal of keeping people and property safe. DRC researchers are using focus groups, surveys, and short questionnaires on a cell phone app to better understand how people decide if specific weather is threatening or not.  In addition to other factors, we are specifically focused on how different times and places people find themselves in when they receive warnings might change how they respond to them.  We are also exploring how warnings delivered on mobile phones differ from other types of dissemination methods.  For example, we are examining the ability of apps to deliver individualized storm warning information to people and whether people give their attention differently to warnings received through their phones than they might to more traditional methods of warning delivery.

NSF HDBE: Collaborative Research: Leveraging Massive Smartphone Location Data to Improve Understanding and Prediction of Behavior in Hurricanes

DURATION: September 1, 2020 – August 31, 2023
RESEARCHERS: Rachel Davidson, Tricia Wachtendorf, Sarah DeYoung

FUNDING: National Science Foundation

PROJECT DESCRIPTION:
In this project, newly available anonymous smartphone location data will be used to dramatically improve understanding of how people behave during hurricanes (e.g., how many people will evacuate, when, how, from where, and to where). In this project, we will promote the progress of science by capitalizing on the availability of a new type of data—anonymous location information from smartphones—to make a leap forward in understanding and predicting the behavior of the population during hurricane evacuations. The project will advance national welfare and benefit society by substantially improving the ability to manage future evacuations. During a hurricane, officials make many highly consequential decisions, including issuing official evacuation orders, messaging the public, opening shelters, staging materials, and staff, implementing special traffic plans, executing support for vehicle-less populations, and preparing to undertake rescues. All of these depend directly on how many people are expected to evacuate, when, how, from where, and to where. By providing a more accurate and nuanced prediction of population behavior during hurricanes, this project will enable officials to make those decisions in a more informed and effective way. Our practitioner partners from the Federal Emergency Management Agency (FEMA) and the Florida and North Carolina state emergency management agencies will also help us share findings with the larger emergency management community. Combining the power of the new data with domain expertise based on traditional survey and interview data will advance the science.

NSF LEAP HI: Embedding Regional Hurricane Risk Management in the Life of a Community: A Computational Framework

DURATION: September 1, 2018 – August 31, 2023
RESEARCHERS: Rachel Davidson, Joseph Trainor

FUNDING: Cornell University, East Carolina University, National Science Foundation

PROJECT DESCRIPTION:
A breakthrough in disaster risk reduction will require an approach that views disasters not as abnormal events but as a regular part of a community’s evolution, and disaster risk management as inextricably interwoven with the normal activities of everyday life. In this project, a novel computational modeling framework will be developed using this approach to improve understanding of the underlying dynamics that lead to escalating regional natural disaster risk, and to support design and analysis of public policy interventions to address them. In a system-wide analysis, the Multistakeholder Disaster Risk Management (MDRM) framework will explicitly consider perspectives of and interactions among multiple key stakeholders (government, primary insurers, and homeowners), multiple diverse interventions (e.g., home strengthening, insurance, land use planning), and not just actions that are explicitly risk-focused but “risk-influential” actions as well. The MDRM computational framework will include seven interacting mathematical models representing physically-based simulation of damage, losses, and ways to strengthen homes; decision-making by each main stakeholder type including oligopolistic competition among insurers; and the changing building inventory and regional economy that provide the context. It will be developed with a full-scale application for hurricanes in North Carolina. This project promises improved understanding of the creation and management of regional natural disaster risk by, for the first time, uniting the conceptualization of disasters as part of the normal life of a community with the power of quantitative, dynamic engineering modeling of risk, decision-making, and economics.

NSF SCC-CIVIC-PG TRACK B: An Integrated Scenario-Based Hurricane Evacuation Management Tool to Support Community Preparedness

DURATION: February 1, 2021 – May 31, 2021
RESEARCHERS: Rachel Davidson, Tricia Wachtendorf

FUNDING: National Science Foundation

PROJECT DESCRIPTION:
As a hurricane approaches, emergency managers must determine when and where to issue official evacuation orders. It requires integrating large amounts of uncertain, changing information to make consequential decisions in a short time frame under pressure, and the stakes are high. An opportunity exists to leverage recent research—in particular, the Integrated Scenario-based Evacuation (ISE) tool—to help meet that challenge. This team designed the ISE tool to be run for a particular hurricane as it approaches the U.S. When run at a point in time, it generates a set of contingency plans and defines the circumstances under which to implement each, depending on how the hurricane evolves. Each plan includes recommendations about whether or not to issue an evacuation order for each geographic evacuation zone, and if so, when. While the new technology has promise, moving from research to practice brings its own challenges. The objectives of Stage 1, therefore, are to: (1) Determine how the new tool and its output can support emergency managers’ natural decision-making process; (2) Conduct a needs assessment for the tool; and (3) Advance understanding of community innovation in disaster management. The Stage 2 objective is to implement an operational prototype of the ISE-based decision support tool for North Carolina. The emergency manager partners will ensure the tool is of practical use; the researchers will ensure it reflects the best science, and the industry partner will ensure its impact is sustainable by hosting it on their platform.

NSF: Multi-Perspective Evacuation Performance

DURATION: September 1, 2015 – August 31, 2020
RESEARCHERS: Joseph Trainor

FUNDING: National Science Foundation

PROJECT DESCRIPTION:
This project combines sociological, engineering, and economics approaches to explore the question of what makes an evacuation a success or a failure. This question is explored from two perspectives: that of the transportation agencies charged with managing an evacuation, and that of the individual households who participate in the evacuation. Through focus groups, a survey, and simulations, this project is exploring how these two groups experience evacuations, and by what criteria they deem an evacuation “good” or “bad”. The project will attempt to quantify these criteria into measurable variables, which can be used to form models to evaluate how much of a success or failure an evacuation is, according to these two perspectives. These models could be used to evaluate the impact of different evacuation strategies, in order to enable authorities to conduct evacuations that are more successful, both for the agencies that manage them and the households that participate in them. Project Status as of January 2018: The design phase of the project has been concluded, and the design of data collection instruments is complete. IRB approval on design and data collection methodology and instruments has been obtained, and the project has entered the data collection phase.

The Emergency Medical Services Delivery in Mass Gathering Events: A Case Study Of The Hajj

RESEARCHERS: Abdulhadi Al Ruwaithi

FUNDING: Umm al-Qura University

PROJECT DESCRIPTION:
Mass gatherings occur more frequently in today’s world, and they have increased in size and magnitude. They can be organized/regular events or non-organized/irregular events, local or international, and peaceful or aggressive. One of the best well-known of these international mass-gathering events is the Hajj (or pilgrimage to Mecca), which occurs annually when over three million people come to a defined area within a very well-known schedule to perform a set of specific Islamic rituals. Over its long history, the Hajj has been prone to many documented risks -either security-related risks, health-related, or others- which are attributed to factors such as transportation, human mistakes, and diverse international attendance. Several instances happened in the past when those risks materialized. It is in this context that studying the response of public health and emergency organizations in these mass-gathering events can generate knowledge for improving the safety of those attending these events. This dissertation project focuses on investigating the emergency medical services delivery system in the Hajj sites, to reveal the factors associated with the EMS systems’ successes and failures during both regular times and emergencies. The project aims to understand factors that impact the EMS process within the Hajj mass gathering context. A mixed-methods approach is utilized by which the patients’ presentation statistics are analyzed and a stratified sample of EMS ambulance crews are interviewed using a semi-structured interview guide. The quantitative approach is used to evaluate the EMS response time and inform the sample stratification process. The qualitative approach (interview data) is used to evaluate the intra- and inter-organizational coordination between the ambulance operators and other agencies in the Hajj.

TNC: Legal Tools for Floodplain Management

RESEARCHERS: A.R. Siders

FUNDING: The Nature Conservancy

PROJECT DESCRIPTION:
Climate change and development are exacerbating flood-risk across the United States. Numerous legal tools exist to help local governments minimize flood risk, and this project seeks to understand and address challenges that limit the ability of local governments to use these tools or shape the outcomes they are able to achieve. The team developed communication tools to facilitate conversations about managed retreat with government officials and members of the public. Interviews with officials who have administered floodplain property acquisition programs explore how federal policy shapes local decisions and how variations in local administration affect participant outcomes. Case studies of municipalities that have adopted progressive development regulations explore what factors enable the adoption and enforcement of progressive laws.

UD GUR: Infant Feeding in Emergencies: Measuring Changes During Natural Hazards in the United States

DURATION: June 1, 2020 – May 31, 2022
RESEARCHERS: Sarah DeYoung

FUNDING: UD General University Research (GUR)

PROJECT DESCRIPTION:
The research aim for this project is to identify the ways in which hazards and disasters impact infant feeding. Specifically, while pre- and post-data from previous work indicates that disaster evacuations reduce rates of breastfeeding (DeYoung, Chase, & Pensa-Branco, 2018) and may increase use of infant formula, additional research is needed to clarify the mechanisms for this change, and whether the reduction in breastfeeding occurs in multiple hazards contexts, and to what extent these findings are generalizable to the broader populations impacted by disasters. Specifically, the DeYoung et al., 2018 study was conducted among a non-random sample of evacuees from the 2016 Fort McMurray wildfire. Caregivers indicated challenges with access to adequate infant feeding supplies for breastfeeding, bottle-feeding, and mixed feeding. Additionally, qualitative data after the Nepal earthquake (DeYoung, Suji, & Southall, 2018) suggests that choices about infant feeding among families displaced by the earthquake were influenced by breastmilk substitutes distributed by nongovernmental groups (NGO’s). However, additional research is needed to clarify the effect of disasters on infant feeding. Identifying inhibiting factors for sustained breastfeeding and safe artificial feeding during and after disasters can inform new interventions and policies used in mass care and evacuation scenarios. This research will employ a mixed-methods approach to identifying the key variables for bolstering safe infant feeding in emergencies.

UDRF: Infant Feeding in Emergencies: Measuring Changes During Natural Hazards in the United States

DURATION: June 1, 2020 – May 31, 2022
RESEARCHERS: Sarah DeYoung

FUNDING: UD Research Foundation (UDRF)

PROJECT DESCRIPTION:
The research aims for this project are to identify the ways in which hazards and disasters impact infant feeding in the United States and to identify key variables for bolstering safe infant feeding in emergencies. Specifically, while data from previous work indicates that disaster evacuations reduce rates of breastfeeding (DeYoung, Chase, & Pensa-Branco, 2018) and may increase use of infant formula, additional research is needed to clarify the mechanisms for this change, and whether the reduction in breastfeeding occurs in multiple hazards contexts, and to what extent these findings are generalizable to the broader populations impacted by disasters. Specifically, the DeYoung et al., 2018 study was conducted among a non-random sample of evacuees from the 2016 Fort McMurray wildfire in Canada. Caregivers indicated challenges with access to adequate space for breastfeeding in emergency shelters and a lack of access to supplies for safe bottle-feeding. Additionally, findings from qualitative research after the Nepal (Gorkha) earthquake (DeYoung, Suji, & Southall, 2018) suggest that choices about infant feeding among families displaced by the earthquake were influenced by breastmilk substitutes distributed by nongovernmental groups (NGO’s). Additional research is needed to clarify the effect of disasters on infant feeding.

UM/NSF CRISP TYPE 2: Interdependencies in Community Resilience (ICOR): A Simulation Framework

DURATION: September 1, 2016 – August 31, 2021
RESEARCHERS: Ben Aguirre

FUNDING: National Science Foundation, University of Michigan

PROJECT DESCRIPTION:
Natural hazards engineering, and disaster science more broadly, have evolved into a multitude of highly specialized disciplines, each dedicated to handling a subset of the overall challenge of mitigating the effects of natural hazards. While progress in each discipline has varied by the historical size of its research community and amount of resources devoted to it, a common observation is that computational research is widespread in all fields. By exploiting this state of affairs and using computational modeling as a common language to link disparate disciplines, this project’s proposed computational platform will open the door for researchers to collaborate in new ways. Users will be able to connect their individual computational models (simulators) to the proposed integrative platform and simultaneously run them with simulators from other disciplines to explore the complex interactions that take place between the different systems of society during and after natural hazard disasters. The ability to seamlessly interface with other models with minimal effort will foster entirely new collaborations between researchers who do not traditionally work together, enabling as-of- yet unimagined studies within and contributions to the natural hazards engineering and disaster science fields. The new understanding that will result from this effort will shed light on the complex interactions that take place between policy, casualty rates and community resilience and clarify to what extent policy changes need to be implemented to significantly influence a community’s level of resilience to natural disasters. The work will also have a substantial impact on the development of human resources. By bridging civil engineering, social science and computer science, the students who will work on this project will attain a truly multi-disciplinary education at the intersection of these disciplines.

Understanding the Relationship Between Household Decisions and Infrastructure Investment in Disaster Recovery: Superstorm Sandy

RESEARCHERS: Sue McNeil, Joseph Trainor

FUNDING: US Department of Transportation through the Center for Advanced Infrastructure and Transportation University Transportation Center at Rutgers

PROJECT DESCRIPTION:
This study uses an exploratory, multiple case study methodology to explore the most influential factors associated with household decision making in two communities, Oakwood Beach in Staten Island, NY, and Sea Bright, NJ. Both communities suffered substantial losses from the hurricane. They are also both small, coastal communities. The population of Oakwood is 12,038 and the population of Sea Bright is 1,414. They also have key differences. Oakwood is the site of a pilot project that will give homeowners 100% of their pre-Sandy home value with an additional 5% if they choose to rebuild on Staten Island. Sea Bright, on the other hand, is rebuilding in the same location. Data collection for each case study community included a survey and semi-structured, in-depth interviews with adult members of households that sustained substantial damages from Hurricane Sandy. Qualitative and quantitative analysis of survey results and interviews was used to test hypotheses identified in the literature. These results were also connected to the impact of infrastructure disruptions.

USDA: Strengthening Local, Regional, and National Emergency Poultry Disease Response

DURATION: January 1, 2020 – December 31, 2020
RESEARCHERS: Jennifer Horney

FUNDING: U.S. Department of Agriculture, National Animal Disease Preparedness and Response Program

PROJECT DESCRIPTION:
This project enhances local, regional, and national emergency poultry disease response. Timeliness is essential to control fast-moving diseases such as avian influenza or Newcastle disease. Local and regional responders can provide an initial capacity prior to mobilization of national level resources such as National Veterinary Stockpile equipment and contractors. On the Delmarva Peninsula, emergency poultry diseases are managed collaboratively between states and agencies and utilize a three-part model in which government, industry, and academia come together to save poultry. This project will strengthen response and enhance teamwork through mutual training in depopulation, epidemiology training on agriculturally important animal diseases; grower training on expectations and roles during an emergency; and grower and industry-oriented mass disposal training.

RESEARCHERS: Sue McNeil, Joseph Trainor

FUNDING: Center for Advanced Infrastructure and Transportation

PROJECT DESCRIPTION:
The focus of this project is to understand how diverse, large data sets support asset management decision-making post disaster. In particular, the focus is on integrating sensor, survey, demographic, vulnerability and condition data related to the supporting infrastructure, the community, and households.
