Past hurricane experiences were less useful than they would have been for a more typical hurricane, as many noted in their social media posts, e.g., " ... We've had hurricanes before, but not like this one - so I don't know at all what to expect, really." The monologic series of social media posts enable study of those affected over the duration of the hazard and better understand social media expression especially from voices that are otherwise overcome by the highly public and therefore "louder" experiences of disaster. First, to isolate the people who might have experienced both flash flood and tornado hazards during Hurricane Florence, we collected all tweets from 8 September to 20 September 2018 containing both a tornado-related keyword ("tornado", "funnel cloud") and a flash flood-related keyword ("flood", "flash flood", "storm surge"), including keywords as hashtags (e.g., "#flood").

The temporal dimension is an often overlooked aspect of human interaction. The treatment and valuation of our own time and others' time is dependent on the social context. The representation of time and time intervals are socially constructed concepts, strongly influencing our behavior. Time's technologies—clocks and calendrical systems—arose from social requirements; they in turn enforce social function. In particular, the institution of the schedule—made possible by the ubiquity of clocks and calendars—has been called a "cornerstone of social life" (Zerubavel, 1981). This paper examines the sociotemporal order in the context of public and personal schedules, with an emphasis on time and human interaction in the workplace. Sociotemporal theory is used to explore what role an emerging time-management technology will have in the workplace: networked, on-line scheduling software.

As social media--which includes blogs, social networking environments, person-to-person and broadcast messaging, and other Web 2.0 applications--becomes more pervasive, their use has significant implications for emergency management practice and policy. Information and communication technology (ICT) enables people--disaster survivors, curious observers, and those who wish to help victims--to connect to one another and to participate in events, including seeking and providing information peer-to-peer. In this article, the author investigated the use of social media during and after the Virginia Tech shootings and the 2007 Southern California wildfires. The author also has examined the characteristics of online "social convergence" across recent crisis events. (Contains 5 endnotes.)

Crisis situations are ripe for expansion of the neogeographer population and skill set. We qualitatively examine the design and creation of crisis map mashups to describe emergent neogeographic practices in this particular domain. We analyze the circumstances that led to their creation, data selection, and design choices vis-a-vis spatial and temporal information representation. We then discuss the implications of emergent neogeographic practice based on two case examples, which illustrate the merging of professional and participatory geotechnologies, and the opportunity a blending of the two provides for widespread cartographic literacy. KEYWORDS: Crisis informatics, disasters, mashups, neogeography, Introduction The mapping of crisis information online is on the rise among nonprofessional cartographers. Map-based 'web mashups' result from the application of social media or Web 2.0 technology to existing [...]

Byline: Amanda Lee Hughes, Leysia Palen This paper offers a descriptive account of Twitter (a microblogging service) across four high-profile, mass convergence events – two emergency and two national security. We statistically examine how Twitter is being used surrounding these events, and compare and contrast how that behaviour is different from more general Twitter use. Our findings suggest that Twitter messages sent during these types of events contain more displays of information broadcasting and brokerage, and we observe that general Twitter use seems to have evolved over time to offer more of an information-sharing purpose. We also provide preliminary evidence that Twitter users who join during and in apparent relation to a mass convergence or emergency event are more likely to become long-term adopters of the technology.
