AbstractHurricanes Katrina and Rita struck the US Gulf Coast in 2005, leading to the largest mass evacuation in US history and straining the region’s transportation infrastructure and services. This case study addresses the topic of disaster response to transportation unmet needs through an unprecedented spatial and longitudinal analysis of transportation-related disaster 2-1-1 call data collected in real-time, allowing for the investigation of unmet transportation needs by location and disaster phases. The authors analyze 25,205 transportation-related calls logged in Texas’ 25 regional 2-1-1 Area Information Centers from August 1 to December 31, 2005, including a baseline period before Hurricane Katrina, evacuation and landfall, and 3-months recovery post-Hurricane Rita. The spatial results show that transportation unmet needs were concentrated in Texas’ major metropolitan areas, especially in Houston-Galveston, and along highway evacuation routes. However, after controlling for population size, areas close to the landfall site and evacuation destinations had greater unmet transportation needs. Longitudinally, transportation unmet needs surged during evacuation and immediate disaster response then returned to baseline levels during recovery. Based on the results of the case study analyzing Texas 2-1-1 call data of unmet transportation needs, strategies and policies for improving mass evacuation and transportation support services are proposed and discussed.

Abstract Background and methods This paper addresses, in simulation, energy minimization of an autonomous electric minibus operating in an urban environment. Two different case studies have been considered, each involving a total of 10 different 2?km bus routes and two different average speeds. In the proposed method, the minibus follows an optimized speed profile, generated using a genetic algorithm. Results In the first case study the vehicle was able to reduce its energy consumption by around 7 to 12% relative to a baseline case in which it maintains a constant speed between stops, with short acceleration and deceleration phases. In the second case study, involving mass variation (passengers entering and alighting) it was demonstrated that the number of round trips that can be completed on a single battery charge is increased by around 10% using the proposed method.

Why do disasters sometimes lead to the creation of innovative, new policy frameworks? People often assume that this happens because disasters cause people to understand environmental problems in new ways. However, this case study of changes in Louisiana’s coastal land management policy after Hurricanes Katrina and Rita in 2005 tells a different story. After the hurricanes, state and federal legislators passed several laws that created a framework for comprehensive coastal restoration, replacing the haphazard and poorly funded approach that preceded the storms. This policy innovation occurred because the hurricanes created an opportunity to enact ideas developed by a coalition of coastal scientists, environmental attorneys, and local businesspeople during the previous three decades. Without the long-term work of this advocacy coalition, policy innovation would probably not have occurred. The case study presents the history of coastal restoration policy in Louisiana and explains how this history illustrates models of policy agenda setting from political science and environmental problems construction from sociology. In turn, these models provide a key to interpreting other examples of post-disaster policy change.

ABSTRACTVerbally agitated behaviours are among the behavioural symptoms of dementia most commonly encountered in long-term care facilities. These behaviours may be related to unmet needs that cannot be expressed adequately because of cognitive impairment. The objective of this preliminary study is to assess an intervention, based on the needs of social attention, sensory stimulation, and comfort, for managing verbally agitated behaviours in long-term care demented patients. A multiple baseline case study design was used, with two participants.

In this paper computational fluid dynamics is used to provide a proof of concept for controlled flow separation using thermal wall interactions with the velocity boundary layer. A 3D case study is presented, using a transition modeling Shear Stress Transport turbulence model. The highly loaded single slot flap airfoil was chosen to be representative for a light aircraft and the flow conditions were modeled after a typical landing speed. In the baseline case, adiabatic walls were considered while in the separation control case, the top surface of the flaps was heated to 500 K. This heating lead to flow separation on the flaps and a significant alteration of the flow pattern across all the elements of the wing. The findings indicate that this control method has potential, with implications in both aeronautical as well as sports and civil engineering applications.
