Abstract |
Many proposed technological solutions to emergency response during disasters involve the use of cellular telephone technology. However, cell phone networks quickly become saturated during and/or immediately after a disaster and remain saturated for critical periods. In this study, we investigated cell phone use by Virginia Tech students, faculty and staff during the shootings on April 16, 2007 to identify patterns of communication with social network ties. We administered an online survey to a random sample from our pool to capture communications behavior with social ties during the day of these tragic events. The results show that cell phones were the most heavily used communication technology by a majority of respondents (both voice and text messaging). While text messaging makes more efficient use of bandwidth than voice, most communication on 4/16 was with parents, since the majority of the sample is students, who are less likely to use text messaging. Our findings should help in understanding how cell phone technologies may be utilized or modified for emergency situations in similar communities. |

Abstract |
Many observers heralded the use of social media during recent political uprisings in the Middle East even dubbing Iran's post election protests a “Twitter Revolution”. We seek to put into perspective the use of social media in Egypt during the mass political demonstrations in 2011. We draw on innovation diffusion theory to argue that these media could have had an impact beyond their low adoption rates due to other factors related to demographics and social networks. We supplement our social media data analysis with survey data we collected in June 2011 from an opportunity sample of Egyptian youth. We conclude that in addition to the contextual factors noted above, the individuals within Egypt who used Twitter during the uprising have the characteristics of opinion leaders. These findings contribute to knowledge regarding the role of opinion leaders and social media, especially Twitter, during violent political demonstrations. © 2012 ISCRAM. |

Abstract |
The Four Phase Model of Emergency Management has been widely used in developing emergency/disaster response plans. However, the model has received criticism contrasting the clear phase distinctions in the model with the complex and overlapping nature of phases indicated by empirical evidence. To investigate how phases actually occur, we designed PhaseVis based on visualization principles, and applied it to Hurricane Isaac tweet data. We trained three classification algorithms using the four phases as categories. The 10-fold cross-validation showed that Multi-class SVM performed the best in Precision (0.8) and Naïve Bayes Multinomial performed the best in F-1 score (0.782). The tweet volume in each category was visualized as a ThemeRiver[TM], which shows the 'What' aspect. Other aspects – 'When', 'Where', and 'Who' – Are also integrated. The classification evaluation and a sample use case indicate that PhaseVis has potential utility in disasters, aiding those investigating a large disaster tweet dataset. |

Abstract |
The wide distribution of cell phones with messaging, email, and instant-messaging have enabled the emergence of a culture of connectedness among segments of society. One result of this culture is an expectation of availability that exists among members of these social networks. This study explores the potential for this expectation to influence perceptions of using information communications technologies (ICT) during and after a crisis. Online survey and follow-up semi-structured interviews were conducted with Virginia Tech (VT) students, faculty and staff to understand whether expectations of connectedness affected their perceptions of their reach-ability during crises. Participants with higher expectations of connectedness also reported more problems with reach-ability. Those with the most problems with reach-ability differed from those with no reachability problems for many variables including satisfaction with the cell phone service, age, number of calls/text messages, and extroversion. Results suggest these communities consider planning how to use ICT during emergencies. |
