Item The actions of institutional leadership at two Louisiana community colleges in the aftermath of Hurricanes Katrina and Rita(2013-12) Nevils, Henry Lane; Saenz, Victor B.; Sharpe, Edwin ReeseIn August and September of 2005, Hurricanes Katrina and Rita devastated the Gulf Coast with damages estimated at $85 billion. Hurricane Katrina was so devastating that the number of lives lost and injuries sustained is still being calculated. Hurricane Rita, which made landfall in the southwestern part of the Louisiana just a few weeks after Katrina, did not cause as much damage as Katrina but was devastating nonetheless. In both cases, two Louisiana community colleges, Nunez Community College and SOWELA Technical Community College, were damaged to the point that many doubted that either college would have a future. Both community colleges, however, continued classes and are in operation today. This study examines the actions of the institutional leadership at Nunez Community College and SOWELA Technical Community College in the aftermath of Hurricanes Katrina and Rita. A constructivist grounded theory approach was used to conduct case studies on each college. A substantive theory emerged from the findings explaining the resiliency of both institutions.Item Households? Evacuation Decision in Response to Hurricanes Katrina and Rita(2014-08-07) Huang, Shih-KaiAlthough evacuation has been recognized as an effective protective action in responding to a hurricane emergency, it is still not clear why some people leave but others do not. In order to better understand this issue, this study began with a statistical meta-analysis (SMA), which is a procedure that has never been conducted previously in the field of disaster studies. The SMA indicates that homeownership, official warning, risk area, seeing peers evacuating, expected hydrological impacts, and expected wind impacts have strong and consistent effects on evacuation decisions whereas female gender, black ethnicity, presence of children in the home, reliance on news media for storm information, reliance on peers for storm information, and hurricane intensity have weaker effects that might be due to mediation through psychological variables. Next, this study collected data from the Hurricane Katrina and Rita evacuations and extended the results of the SMA by testing the Huang et al. (2012) abbreviated protective action decision model (PADM). The results show that (1) a household?s evacuation decision, as predicted, is determined most directly by expected wind impacts and expected evacuation impediments. In turn, expected wind impacts and expected hydrological impacts are primarily determined by expected storm threat and expected rapid onset. Finally, expected storm threat, expected rapid onset, and expected evacuation impediments are determined by households? personal characteristics, their reception of hurricane information, and their observations of social and environmental cues. (2) Surprisingly, expected hydrological impacts did not have as much of an impact on evacuation decisions as wind impacts?which are associated with expected injuries, job disruption, and service disruption. (3) Official warnings and risk area also had direct effects on households? evacuation decisions, which can be explained as the peripheral route to persuasion that bypasses messages about the personal impacts hurricane impact (Petty & Cacioppo, 1986). (4) Unlike other hurricane evacuation studies, this one found that expected rapid onset had a significant effect on households? evacuation decisions, perhaps because both Hurricanes Katrina and Rita had late-changing tracks that might have caused residents to be concerned being caught on the road by a rapidly approaching storm. (5) Supplemental information, such as environmental cues, risk area, and hurricane experience, have effects on individuals? expectations of storm threat, wind impacts, and hydrological impacts that are similar to those of National Weather Service information that is disseminated through multiple information channels (e.g., news media and official warnings). This implies that households used other sources to place the National Weather Service?s hurricane information into an appropriate context. Nonetheless, some of the results conflict with the model presented by Huang et al. (2012), so further research is needed to determine whether the conflicting results can be replicated and, consequently, require revision of the model.Item The Impact of Tropical Cyclones on the Geomorphic Evolution of Bolivar Peninsula, TX(2012-07-16) Hales, BillyAnnually, tropical cyclones do tremendous damage and are agents of long-term coastal change. To test this idea of different tropical cyclones delivering consistent coastal change, a landform with such evolution is needed. One such landform is a spit. What contributions do tropical cyclones give toward the evolution of a spit, and do tropical cyclones give the same kinds of impacts? To determine if tropical cyclones have similar impacts, shoreline and volumetric change from four storms impacting Bolivar Peninsula are considered. Being a southwest-trended spit at a length of 33.5 kilometers, storm impacts are measured in the form of one dimensional shoreline and two dimensional volumetric change. These impacts are abstracted into shoreline change and volumetric change patterns. These patterns are identified and compared for differences between each storm and similarity among all storms. Results indicate that shoreline accretionary zones vary alongshore. Results from Hurricane Ike indicate an accretionary zone ten kilometers from the distal end. Shoreline change patterns for Hurricane Rita show an unstable accretionary zone at four kilometers from the distal end. Results for Tropical Storm Fay indicate an unstable accretionary zone that begins at the distal end and continues to the middle of the spit. In terms of similarity for shoreline change, all patterns from storms demonstrated erosion near Rollover Fish Pass. One dimensional volumetric change patterns were entirely erosive for Hurricanes Rita and Ike, and Tropical Storm Fay had by small zones of accretion near the distal portion of the spit. Tropical Storm Josephine demonstrated an accretion zone between the middle and distal portion of the spit. Results from two dimensional volumetric change patterns suggest a threshold for inland penetration. Tropical Storm Fay showed a ten to twenty meter wide pattern of erosion around five kilometers from the distal end and near the proximal end of the spit, and Hurricane Rita demonstrated a twenty meter wide pattern of erosion near the distal end. Hurricane Ike had erosive penetration of up to 200 meters around fifteen kilometers from the distal end. Results suggest that certain storms reinforce the standard spit growth model, and others work against it.
