Disaster relief

Natural disasters often result in large-scale power outages. Real-time tracking of the extent, distribution, and timelines of electrical service loss and recovery can play an important role in minimizing disaster impacts. Using NASA's Visible Infrared Imaging Radiometer Suite (VIIRS) Day/Night Band (DNB), the extent and duration of disrupted electric utility infrastructure in the Florida Panhandle following Hurricane Michael were estimated. The percent loss of electrical service was downscaled to a neighborhood level using the 2013-2017 American Community Survey (ACS) data at the block group level. Two ordinary least square models were estimated to examine the association between socioeconomic characteristics and the extent and duration of the power outages as well as recovery rates. The study found that block groups with higher percent minorities, multi-family housing units, rural areas, and a higher percentage of households receiving public assistance were experiencing slower power restoration rates than urban and more affluent neighborhoods. The findings have implications for disaster preparedness and recovery planning.

The trauma and devastation that resulted from Hurricane Katrina's landfall on August 29, 2005, produced a wide spread public perception of government neglect and ineptitude. Subsequently, a period of nationwide shame and concern for those most affected by the disaster elicited a wave of financial generosity from all social sectors. Yet, by late 2005 the media declared that the majority of Americans had become desensitized to the tragedy and its consequences, coining this shift in public perception as "Katrina fatigue." Thousands of volunteers contradicted this phenomenon, however, by performing service in the devastated city of New Orleans. Long-term volunteers defied "Katrina fatigue" by redirecting the trajectory of their lives so they could provide service. Conventionally accepted volunteer theory predicts that volunteers provide service and that their labor operates in conjunction with institutionally supported mechanisms of security and services.

Disasters are unavoidable. The United States separates the phases of addressing a disaster into Response and Recovery. There are systems in place for Response; but Recovery, a fundamental process for countries to rebound from disasters, is a topic that is left aside. Recently the U.S. released a framework regarding this topic and it is the intention of this work to further explore recovery by starting a modeling process for disaster management systems by developing a Disaster Recovery Roles Pattern based on the framework and creating flowcharts using the Business Process Modeling Notation for use in future development of systems for the recovery process.

This dissertation explores how local government policies affect pre-and postdisaster business resilience, in the context of institutional and neo-institutional frameworks. The study builds on past research on business vulnerability and resilience to examine government policies in the pre-disaster and response and recovery periods, and explore how government responses of varying types can contribute to different outcomes for local small businesses in the recovery period following hurricane disasters. The project examines two cases surrounding events in 2005 and their impact on business resilience: Hurricane Katrina and its effects on the New Orleans metropolitan area; and Palm Beach County's experience with Hurricane Wilma. The dissertation involves a mixed-method approach to the subject matter. The statistical analysis portion uses multiple regression analysis of surveys of government-registered business owners in the affected areas. Business resilience is examined in light of the p redictive power of the size of the disaster; the influence of the institutional policies in public procurement, and vii economic development through small business programs; the role of institutional culture; and finally business vulnerability. The interview portion involves interviews with public officials, and coding and analysis of the field texts of these discussions, for additional information about the role that institutions play in the resilience of businesses before and after disaster. The statistical results suggest that institutional culture; size of disaster, institutional policies (particularly in procurement practices), and vulnerability can play a role in determining the resilience of a local business community.
