This paper presents descriptive accounts from an ethnographic study of time-critical work in the domain of emergency response and the operative work of fire crews. The verbal communication as part of such work creates difficulties in providing accountability of the fire crew's actions. The concept of work rhythms and temporal structures is used as an(More)
This paper reports on an explorative project aimed to study the use of live video technology in emergency response work. The initial stage of the project aimed at enabling an emergency response organization with live video capabilities. The study covered the steps of design, development and deployment of an application for live video broadcasting. Over a 10(More)
This paper presents descriptive accounts of time-critical organizing in the domain of emergency response. Patterns of mobile phone interaction in such work is analyzed showing how the dyadic exchange of mobile phone numbers between the actors plays an important role in the social interactions in the organizing and sensemaking of the emergency.

Decision making during crises takes place in (multi-agency) teams, in a bureaucratic political context. As a result, the common notion that during crises decision making should be done in line with a Command & Control structure is invalid.

Coordination bodies that attempt to overcome coordination barriers in humanitarian relief face many challenges. Among them are general organizational barriers to coordination as well as functionally-oriented barriers arising specifically from information management (IM) and information technology (IT) issues. Based on data collected from three coordination(More)
Developments in information and communication technology (ICT) have adjusted the opportunities for spatial and temporal representations of data, possibly permitting the simultaneous visualization of how different regions and populations are affected during large-scale emergencies and crises. We surveyed 13 crisis-related mashups to derive some high-level(More)
In this paper we present an ontology-based system for managing emergency alert notifications. Our purpose is to generate emergency alerts that are accessible to different kinds of people, paying special attention to more vulnerable collectives like impaired people. By adapting alerts to different devices and users we can allow Emergency Management Systems(More)
Effective handling of location-based data is important to emergency response management (ERM). Expert team members co-located around maps typically discuss events while drawing freeform areas or while using physical placeholders representing incidents. Key ERM functions are filtering data, selecting information recipients, searching datasets, drawing(More)
