The Study of Crisis Narratives Over Time: Mayfield, KY in the Aftermath of the 2021 Tornadoes

Freihaut, Rebecca 01 January 2023 (has links) (PDF)
This study was a year-long longitudinal qualitative research project using the case study of Mayfield, KY after the catastrophic tornado event that impacted their community on December 10, 2021. Oral histories were collected from 18 participants who lived in or were closely connected to Mayfield at the six month and 1.5 year marks after the disaster. Later, after the oral histories were archived and made available to the public, the transcripts were used to extract the crisis narratives from the oral histories and the data was thematically analyzed using the existing theory and theoretical framework of Narratives of Crisis: Telling Stories of Ruin and Renewal by Seeger and Sellnow (2016). The themes were analyzed to better understand how crisis narratives change over time and to determine if there were differences between the leadership of Mayfield and their stakeholders, the public. A major finding in this area was the intertwining of one of more themes within the same passage of narrative, including the intertwining of traditionally competing themes. This extends the theory of Narratives of Crisis. The Discourse of Renewal by Ulmer and Sellnow (2002) was also used to analyze how narratives may differ between those in the community who are considered leaders, and those who represent a general cross-section of the community. The major finding in this analysis was the lack of up-to-date information between leaders and the public. By not creating a bridge of communication, many of the successful steps taken by leaders may not have reached their intended audience. One of the components of the Discourse of Renewal, organizational learning, was specifically used to find lessons learned discussed by community leaders in Mayfield, and to explore how these learned lessons can be applied for practitioners to better understand disaster recovery and renewal in the future.

Exploring Spontaneous Planning During the North Texas April 3, 2012, Tornadoes: an Assessment of Decision-making Processes

Peters, Ekong Johnson 08 1900 (has links)
The primary purpose of this research program is to confirm the spontaneous planning behavior in post-disaster operations while at the same time contribute to the development of the concept in a tornado type disaster. An additional goal also includes examining how the process takes place in resolving unanticipated problems as a disaster unfolds. This study uses qualitative methodology which is case study to probe the concept of spontaneous planning behavior to solve unexpected challenges as a disaster develops. Specifically, semi-structured, open-ended questions were utilized to collect data from stakeholders in eleven functional organizations in three impacted cities during the North Texas April 3, 2012, tornadoes. Findings indicate that debris removal and ensuring public safety, search and rescue, securing damaged neighborhoods, activation of emergency operations centers, damage assessment, restoration of communication system, public relations and media, and volunteer and donation management activities appear to have benefited from spontaneous planning behavior. Further findings suggest that the driving forces behind the phenomenon were gathering valuable new information, learning opportunity within the disaster, relative freedom and significant high degree of discretion, response was innovative with flexibility, and solutions waiting for problems features proposed in the integrated decision-making model (IDMM). However, it was uncovered that interview respondents’ answers tend to indicate that mixed organizational structures helped in problem resolutions rather than just flat organizational structure as some decision making literature may suggest. Analysis of this decision-making model expanded the understanding of how spontaneous planning behavior took place in resolving unforeseen problems in post-disaster operations. This research project confirmed the concept of spontaneous planning in the North Texas tornadoes as well as suggesting how it occurred. The research program validates spontaneous planning behavior in tornadoes; advances and develops the concept of spontaneous planning; increases understanding, description, and management of post-disaster operations; improves emergency management operations; promotes spontaneous planning as a key principle among responders and others involved in emergency management; and proposes IDMM as a useful model that explains decision-making behavior during a disaster.

Tornado Fatalities: An In-Depth Look at Physical and Societal Influences

Key, Heather Joann 01 January 2015 (has links)
The purpose of this study is to model and determine significant predictors of tornado death index values, and to investigate these significant predictors and what makes people vulnerable to tornado fatalities through expert interviews. This study also provides an understanding of the study participant’s perceptions of their county’s vulnerability to tornado fatality and demonstrates a true integration of methods and fields by studying geographic, meteorological, and sociological phenomena by use of quantitative and qualitative methods. The study consists of two parts: 1) A quantitative exploration of variables hypothesized to predict Tornado Death Index (TDI) values, 2) A qualitative investigation to further understand what leads to higher tornado fatalities. For the quantitative portion of the study descriptive statistics and multiple linear regressions were run on TDI values. It was predicted that several tornado characteristic, demographic, housing type and characteristic, religious, region, rural vs. urban, and potential casualty variables were significant predictors of TDI values. For the qualitative portion of the study a highest order emergency manager was interviewed, coding was done and themes, sub-themes, and categories emerged, and quotes that demonstrated the themes and categories were examined. Overall, significant predictor variables of TDI are tornado frequency, tornado width, ages 35-44, percent born in the Northeast, percent rural housing units, and potential casualties. As tornado width, and percent of rural housing units increases TDI increases (positive relationship), whereas as tornado frequency, ages 35-44, being born in the Northeast, and potential casualty increases TDI decreases (negative relationship). In the interview, age, cultural beliefs, and mobility challenges were found to increase risk to tornado fatality. It was also suggested that differences in tornados may exist between the Midwest and the South in terms of tornado development, duration, and warning lead-times. Finally, vulnerability can be reduced by educating the public, and reaching out to vulnerable populations and their caregivers.

The Effects of Hurricane and Tornado Disasters on Pregnancy Outcomes

Christopher, Kenneth E. 01 January 2017 (has links)
Maternal prenatal exposure to hurricanes and tornadoes could contribute to an increased risk for adverse birth outcomes. Little is known about the effects of Hurricane Katrina of August 2005, on pregnancy outcomes in Mississippi. Additionally, little is known about the influence of the April 2011 Alabama tornado disaster on births in that state. The purpose of this study was to bridge this knowledge gap by examining the relationship between maternal prenatal exposure to these storms and adverse infant health outcomes. The theoretical framework guiding this retrospective, cross-sectional study was the life course approach. Data for this investigation included 2,000 records drawn from the Linked Infant Births and Deaths registers. Chi-square and logistic regression analyses were performed. Results indicated hurricane exposure was not a predictor of preterm birth (OR = .723, 95% CI = [.452, 1.16]; p = 1.76) or low birth weight (OR = .608, 95% CI = [.329-1.13]; p = .113). However, an association was observed between tornado exposure and preterm birth (OR = 1.68, 95% CI = [1.19-2.39]; p = < 0.05) and low birthweight (OR = 1.91, 95% CI = [1.27-2.87]; p = < 0.05). Findings suggest pregnant women are vulnerable to natural disaster storms, and are at risk for adverse pregnancy outcomes. The implications for social change include informing preparedness efforts to reduce vulnerability to increased pregnancy risk factors and adverse birth outcomes, consequential to hurricane and tornado disasters.
