A survey distributed in the months prior to the fall 2018 midterm elections collected data on political affiliation, level of education attained, trust in the media, and the perceived effectiveness and re-electability of United States President Donald Trump. Data were examined by educational attainment only, then by educational attainment of those indicating a political affiliation of Democrat, Republican, or Independent/Other. While some significant relationships emerged, overall, there was no indication of the DKE present in responses focused on the media. A further examination of question coupling was undertaken, which revealed that respondents with lower education levels created illogical response couplings more frequently than respondents with higher education levels. Respondents that indicated they did not follow politics, were uninformed concerning politics, did not think that the media was accurate, and did not trust the media, were shown to construct definitive answers concerning questions that require knowledge of politics in the present. While no political affiliation was attached to the last response group, educational attainment was, which showed that those in lower attainment categories comprised at least two-thirds of the group respondents who constructed illogical or contradictory response couplings. Inattention while completing the survey may explain some of the effects, but the DKE does appear to be present in the results.

Spa- tial and temporal clustering may be evident in certain data types that can be used to frame the progress of recovery fol- lowing a disaster. Publically available building permit data from the city of Joplin, Missouri, were gathered for four per- mit types, including residential, commercial, roof repair, and demolition. The data were used to (1) compare the observed versus expected frequency (chi-square) of permit issuance before and after the EF5 2011 tornado; (2), determine if significant space-time clusters of permits existed using the SaTScanTM cluster analysis program (version 9.7); and (3) fit any emergent cluster data to the widely-cited Kates 10-year recovery model. All permit types showed significant increases in issuance for at least 5 years following the event, and one (residential) showed significance for nine of the 10 years. The cluster analysis revealed a total of 16 significant clusters across the 2011 damage area. The results of fitting the significant cluster data to the Kates model revealed that those data closely followed the model, with some variation in the residential permit data path.

Building permit data was used from May 23, 2011-December 31, 2020, to examine recovery progress based on roof repair building permits (permit for roof repair only), residential and commercial building permits, and demolition permits. Each of the four permit types was plotted on the four Federal Emergency Management Agency (FEMA) damage zones, catastrophic, extensive, moderate, and limited, by census block to determine what percentage of total permits were issued in each. Further, data on three permit types (commercial excluded) were plotted in the following combinations: (a) roof repair permits with demolition permits and (b) roof repair permits with residential building permits, plotted on the catastrophic and limited zones only. The goal of the second set of plots was to visualize the 2011 damage path using permit data. Mapping data such as these may help recovery planning through a robust understanding of the relationship between damage and permit issuance as a community enters the restoration phase of the Kates recovery model.

The EF5 tornado was the deadliest single tornado to occur in the United States since modern record keeping began in 1950, surpassing the tornado of 8 June 1953, which claimed 116 lives in Flint, Michigan. The Joplin tornado death toll was also far higher than the average annual number of deaths caused by tornadoes in the United States between 2000 and 2011. This study analyzed Joplin deaths by damage zone and place of death. Tabular data collected primarily from secondary sources revealed the number of deaths and death rates differ significantly by zone of destruction. The central zone (labeled as “catastrophic”) had the most deaths, with the number decreasing systematically in both directions from the center of that zone. The results of this study further show that more people died in nonresidential buildings in Joplin than is usual in a U.S. tornado event, calling in...

Current classifications for natural disasters, such as the Fujita Scale for tornadoes and the Saffir-Simpson hurricane scale, focus on the physical properties of the event, not the impact on a community. Pre-event vulnerability to a natural hazard is determined by factors such as age, race, income, gender, infrastructure, density of the built environment and health of the industrial base. The behavior of residents in the community, construction quality of shelters, and warning system effectiveness also affect vulnerability. If vulnerability is influenced by such factors, post-event impact should be, at least in part, as well. The goal of this research was to develop the Tornado Impact-Community Vulnerability Index (TICV) that utilizes variables such as the number of persons killed, economic impacts, and social vulnerability to describe to the level of impact a tornado event has on community. As tornadoes that strike unpopulated areas are often difficult to classify, even in the traditional sense, the TICV will take into consideration only events that strike communities defined as " places " according to the U.S. Census Bureau. By assigning a rating to the impact, this index will allow the severity of the storm to be understood in terms of its effect on a specific community and hence its impact, rather than in terms of its physical strength.

In doing so, city officials introduced two new safety measures and recommended several others. The main objective of this paper is to explore the tornado survivors’ compliance with the safety features recommended by the Joplin city authorities. Face-to-face interviews, as well as other methods, were used to survey respondents who were living within the tornado path (damage zones) at the time of the tornado. Results showed that 43 percent of all respondents implemented at least one recommended tornado measure in rebuild or repair their destroyed/damaged homes. Further, it was found that three variables considered here--- rebuild or repair, damage zone category, and perceived tornado risk---were all significant contributors to a homeowner’s decision to implement recommended tornado safety measures. The paper concludes with a recommendation for expanding tornado safety education among the respondents. Keywords: May 2011 tornado, Joplin, Missouri, tornado safety measures, recovery and reconstruction.

This event, which claimed the lives of 162 people, represents the deadliest single tornado to strike the US since modern record-keeping began in 1950. This study examines the factors associated with responses to tornado warnings. Based on a post- tornado survey of survivors in Joplin, it reveals that tornado warnings were adequate and timely. Multivariate logistic regression identified four statistically significant determinants of compliance with tornado warnings: number of warning sources, whether respondents were at home when the tornado struck, past tornado experience, and gender. The findings suggest several recommendations, the implementation of which will further improve responses to tornado warnings.

Finally, the lack of basements in residential and other structures most likely contributed greatly to the high death toll, although the degree remains uncertain. Several recommendations are offered to reduce future U.S. tornado fatalities.

Although warning systems have been improved upon in recent years, tornadoes still pose a serious threat to property, and more seriously, human life. The location of emergency warning sirens is an important factor in reducing vulnerability and providing people the necessary lead-time to take shelter when a tornado is approaching. Hammer and Schmidlin (2002) noted that 37 percent of the people in the last 21 km of the path of the 3 May 1999 Oklahoma City tornado received their warning from emergency sirens. The geographical area covered by a siren network is of great interest to the natural hazard community, as proper placement can maximize the area covered and greatly reduce the chance of being injured or killed by a tornado (Brown et al., 2002; Grazulis et al., 1998; Hammer and Schmidlin, 2002). This paper examines some of the geographical and population-driven considerations through an analysis of the siren networks of two counties, Riley and Wabaunsee, in northeastern Kansas.

GIS systems are used to store, manipulate, analyze, and manage all types of geodata, and are widely used by many military organizations in military decision making processes (MDMPs). Apart from accuracy, usage of GIS in MDMPs has provided many advantages, becoming a powerful and popular tool in the militaries of developed countries. However, even though GIS is a sophisticated tool in MDMP, the Sri Lankan Army has not employed widespread use of these systems. Tactical operations in which covert movement is paramount to success depend on high quality data and information concerning enemy positions, as was the case in the Sri Lankan Civil War (1983-2009). A case study of base siting using GIS is explored here; in this research we attempt to introduce GIS as a powerful tool in MDMPs in the Sri Lankan military. Sri Lanka is a developing country that suffered from a terrorist war for more than 30 years. All decision making and data gathering was done manually, spending more money and man power that was realistically necessary. This research is focused on providing solid evidence for the use of GIS techniques in MDMPs, which can partially supplant slower, less reliable human-based decision making processes. In selecting a suitable permanent or temporary military operation base in enemy territory, all parameters need to be evaluated accurately. Injecting logical and statistical data, thus more automated processes into command-level decisions, will minimize errors in MDMPs. The Analytic Hierarchy Process (AHP) is utilized to structure commander's perceptions of important selection criteria, and optimal base selection procedures are described.
