  Title Cell phone use with social ties during crises: The case of the Virginia Tech tragedy Type Conference Article
  Year 2010 Publication ISCRAM 2010 – 7th International Conference on Information Systems for Crisis Response and Management: Defining Crisis Management 3.0, Proceedings Abbreviated Journal ISCRAM 2010  
  Volume Issue Pages  
  Keywords Cellular telephones; Disasters; Information systems; Mobile phones; Telecommunication equipment; Cell phone; Communication technologies; Emergency communication; Emergency response; Emergency situation; Patterns of communication; Survey research; Technological solution; Text messaging  
  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.

  Title Between a rock and a cell phone: Communication and information technology use during the 2011 Egyptian uprising Type Conference Article
  Year 2012 Publication ISCRAM 2012 Conference Proceedings – 9th International Conference on Information Systems for Crisis Response and Management Abbreviated Journal ISCRAM 2012  
  Volume Issue Pages  
  Keywords Cellular telephones; Information systems; Mobile phones; Contextual factors; Information technology use; Innovation diffusion; Innovation diffusion theory; Middle East; Opinion leaders; Social media; Social media datum; Social networking (online)  
  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.

  Title PhaseVis1: What, when, where, and who in visualizing the four phases of emergency management through the lens of social media Type Conference Article
  Year 2013 Publication ISCRAM 2013 Conference Proceedings – 10th International Conference on Information Systems for Crisis Response and Management Abbreviated Journal ISCRAM 2013  
  Volume Issue Pages 912-917  
  Keywords Civil defense; Classification (of information); Data visualization; Information systems; Risk management; 10-fold cross-validation; Classification algorithm; Classification evaluation; Emergency management; Potential utility; ThemeRiver; Through the lens; Twitter; Disasters  
  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.

  Title Expectation of connectedness and cell phone use in crisis Type Conference Article
  Year 2009 Publication ISCRAM 2009 – 6th International Conference on Information Systems for Crisis Response and Management: Boundary Spanning Initiatives and New Perspectives Abbreviated Journal ISCRAM 2009  
  Volume Issue Pages  
  Keywords Information systems; Mobile phones; Telecommunication equipment; Cell phone; Cell phone service; Emergency communication; Information communication; Qualitative; Reachability problem; Semi structured interviews; Structured interview; Cellular telephones  
  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.
