Abstract: What are effective ways to train students for designing Emergency Management Information Systems and for working with distant partners on EMIS projects? This paper describes the results of a project whose goal is to assess the effectiveness of Partially Distributed Teams (PDTs) as a pedagogical strategy. A PDT is one type of distributed team, in which two or more co-located subgroups use information and communication technology to collaborate on a task. Much of emergency management involves cross-organizational and often cross-national collaboration in this form. Students need, but lack, learning experiences focused on how to work effectively in such situations. This field study involved more than 700 students from universities in eight countries, working in 80 teams on an EMIS software requirements task. Results indicate that students report positive learning experiences, with international students in international teams reporting the most positive experiences. There are also significant differences among universities.

Chao Huang, Shifei Shen, & Quanyi Huang. (2012). An approach based on environment attributes for representation of disaster cases. In Z.Franco J. R. L. Rothkrantz (Ed.), ISCRAM 2012 Conference Proceedings – 9th International Conference on Information Systems for Crisis Response and Management. Vancouver, BC: Simon Fraser University.
Abstract: In this paper we overview the ongoing research into the application of case-based reasoning in emergency management, based on which we propose a new approach for representation of large-scale disaster cases. The approach takes the environmental factors into account, and the case is organized according to key scenes, rather than disaster types. Each scene consists of inherent attributes, which are concerned with the disaster type, and environment attributes, which usually facilitate the adjustment of the decision-making, and sometimes play crucial role. To describe the environment attributes, the fuzzy sets are employed to take use of the non-quantitative information. The nearness of the fuzzy sets is used to retrieve the similar case. Based on this approach, the case retrieval could even extract the case with different type but similar environment, supposing the inherent attribute is analogous. © 2012 ISCRAM.

Abstract: This paper describes the design, execution, and results of a participatory design workshop with emergency public information officers (PIOs). During the workshop, PIOs and researchers explored ideas and designs for supporting the social media needs of PIO work. Results indicate that PIO perceptions of social media have changed as they have learned to incorporate activities of the public into their work, yet they still struggle with issues of trust and liability. Based on workshop design activities, the paper offers a set of design recommendations for supporting the social media needs of PIO work practice such as the ability to monitor, document, and report social media activity.

Müller S. Fortier F. F. T. Comes (Ed.), ISCRAM 2013 Conference Proceedings – 10th International Conference on Information Systems for Crisis Response and Management (pp. 951–961). KIT; Baden-Baden: Karlsruher Institut fur Technologie.
Abstract: Successful decision making and task execution in emergency management require appropriate levels of situation awareness (SA). This paper proposes an ontology-based model for the design of a computer-based system, Situation Aware Vigilant Emergency Reasoner (SAVER) that supports the individual, shared and team SA of managers in emergency situations. SAVER is evaluated in simulated experiments that demonstrate the improvements in SA performance. The paper provides a complete description of the SAVER design, implementation, evaluation and its proposed extension from a proof-of-concept to a production environment.

M.A. Santos (Ed.), 8th International Conference on Information Systems for Crisis Response and Management: From Early-Warning Systems to Preparedness and Training, ISCRAM 2011.

Abstract: In this paper, we propose the use of an ontology-based and semantic technologies approach to improving shared situation awareness amongst teams dealing with emergency situations. We have also identified that shared and team situation awareness tends to be viewed only in terms of cooperative task completion and so we have tried to describe their important relationship with team decision making. The applicability of our approaches is demonstrated by a case study of mass evacuation in the case of a tsunami event. We show how ontology can be used to represent context-based situations and how the axioms and rules can improve team situation awareness.

Comes (Ed.), ISCRAM 2013 Conference Proceedings – 10th International Conference on Information Systems for Crisis Response and Management (pp. 376–380). KIT; Baden-Baden: Karlsruher Institut fur Technologie.
Abstract: This paper introduces the latest state of the interoperable Sensor Web and Web Processing standards specified by the Open Geospatial Consortium. Based on these components it becomes possible to share, integrate and analyse observation data across political and administrative borders as well as across multiple thematic domains. We present the 52°North open source implementations of the OGC SWE and WPS standards and introduce an outlook how this technology could be applied in the field of crisis management. Thus, this paper aims at providing a perspective how currently existing technology can be combined and applied to solve problems in emergency management rather than describing an already finished product. Special consideration will be given to the combination of Sensor Web and Web Processing technology which opens up new possibilities by having near real-time data flows that can be linked on-demand to different processing services.

Washington, DC: Information Systems for Crisis Response and Management, ISCRAM.
Abstract: Making a decision in a changeable and dynamic environment is an arduous task owing to the lack of information, their uncertainties and the unawareness of planners about the future evolution of incidents. The use of a decision support system is an efficient solution for this issue. Such a system can help emergency planners and responders to detect possible emergencies, as well as to suggest and evaluate possible courses of action to deal with the emergency. We are interested in our work to the modelling of a monitoring preventive and emergency management system, wherein we stress the generic aspect. In this paper we propose an agent-based architecture of this system and we describe a first step of our approach which is the modeling of information and their representation using a multiagent system.

Abstract: This paper summarises the contribution of EURATOM research to off-site emergency management in Europe over the past two decades. Effort initially focused on the development of methods and software that could be used to underpin the nature and extent of emergency management arrangements and policy. With time, and partially in response to accidents at TMI and Chernobyl, effort shifted to the development of a comprehensive decision support system that could find broad use in real time across Europe in order to better inform decisions on emergency management. The deployment of the developed system across Europe, largely so far at a pre-operational level, is described together with the opportunities this offers for more coherent response to any accident that may in future affect Europe and for better use of scarce resources, both human and otherwise. Indications are given of where further effort or initiatives should be directed with a view to ensuring that the major research achievements are fully and effectively exploited.

French (Ed.), ISCRAM 2010 – 7th International Conference on Information Systems for Crisis Response and Management: Defining Crisis Management 3.0, Proceedings. Seattle, WA: Information Systems for Crisis Response and Management, ISCRAM.
Abstract: A crucial aspect for large-scale disaster management is an efficient technology support for communication and decision-making processes in command and control centers. Yet, experiences with the introduction of novel technologies in this setting show that field professionals tend to remain attached to traditional workflows and artifacts, such as pen and paper. We contribute the results of a comprehensive field study which analyzes how the information flow is currently performed within different units and persons in the command and control center. These findings provide insights into key aspects of current workflows which should be preserved by novel technological solutions. As our second contribution, by using a participatory design approach and based on our findings, we present a novel approach for computer support in command and control centers. This relies on digital pens and paper and smoothly integrates traditional paper-based workflows with computing, thereby combining the advantages of paper and those of computers.

Hughes (Eds.), ISCRAM 2015 Conference Proceedings ? 12th International Conference on Information Systems for Crisis Response and Management. Kristiansand, Norway: University of Agder (UiA).
Abstract: The analysis of cascading effects in crisis situations can enhance crisis managers? understanding of how crises unfold and what prominent triggers of cascading effects are. By identifying and categorising triggers of cascading effects, a greater understanding of critical points in crisis situations can be reached, which can contribute to strengthening practices of crisis management, including preparedness and response. Accordingly, this paper provides an insight into triggers of cascading effects, gained through the analysis of six case studies of crises that took place between 1999 and 2014. The analysis produced six categories of triggers, which are discussed here: the disruption of pre-existing relations of information, organisation, and supply, disturbance relations, pre-disaster conditions, and the malfunctioning of legal and regulatory relations. Authors argue that the categorisation of triggers aids anticipating cascading effects, along with predicting risks and planning for potential bottlenecks in crisis management.

Comes (Ed.), ISCRAM 2013 Conference Proceedings – 10th International Conference on Information Systems for Crisis Response and Management (pp. 747–757). KIT; Baden-Baden: Karlsruher Institut fur Technologie.
Abstract: Spatial partitioning consists of the problem of finding the best segmentation of an area under specific conditions. The final goal is to identify parts of the area where a number of resources could be allocated. Such cases are common in disaster management scenarios. In this paper, we consider such a scenario and propose a methodology for the resource allocation for emergency response. We utilize an intelligent technique that is based on the Particle Swarm Optimization algorithm. We define the problem by giving specific formulations and describe the proposed algorithm. Moreover, we provide a method for separating the area into cells and describe a technique for calculating cell weights based on the underlying spatial data. Finally, we present a case study for allocating a number of ambulances and give numerical results concerning the run time and the total coverage of the examined area.

Rothkrantz (Ed.), ISCRAM 2012 Conference Proceedings – 9th International Conference on Information Systems for Crisis Response and Management. Vancouver, BC: Simon Fraser University.
Abstract: Information is an essential part of disaster management. Information systems (IS) are a key means of providing the right information at the right time to support response to a disaster, and fostering collaborative facilitators such as situation awareness, common ground and communities of practice. However for these collaborative facilitators to support 'downstream events' (i.e. disaster response) they need to emerge and be grown from 'upstream' activities such as user engagement. Subsequently IS design requirements for disaster response are embedded in the community where a system will be used and it is from the community users and their needs that IS requirements must emerge. This paper presents an upstream-downstream approach for disaster management IS design. We describe four phases to user centered information systems design to support disaster management and provide a case study of using this approach in action to design an IS to enhance community resilience. © 2012 ISCRAM.

Abstract: An emergency brings together a group of individuals who often represent different organizations, resources, and roles. In order to be able to make the right decisions, individuals need to understand each other although they may be from different lines of business. In our research the target is to stress the importance of a common language in emergency management. Our plan is to gather a group representing the authorities, i.e. public sector actors, and a group representing companies, i.e. private sector actors, to communicate with the Delphi method on possible differences in the language used in different lines of business. The aim of this paper is to discuss the possibilities of using the Delphi method to make improvements to emergency management and to evaluate which kinds of organizations should be represented in our Delphi panel. This paper forms a part of a larger research study, the results of which will be useful, for example when improving the interoperability of management and communications systems. © 2012 ISCRAM.

Comes (Ed.), ISCRAM 2013 Conference Proceedings – 10th International Conference on Information Systems for Crisis Response and Management (pp. 724–729). KIT; Baden-Baden: Karlsruher Institut fur Technologie.
Abstract: In emergency management, the identification of hazards, analysis of risks, development of mitigation and response plans, maintaining of situational awareness and support of response and recovery are all complex responsibilities. A major accident brings together individuals belonging to many different organizations, having backgrounds in different fields of operation, and representing different organizational cultures. They have to absorb a large amount of information about the accident over a short period of time. In order to take effective action, actors are expected to work smoothly together, thus the flow of information from and to the actors involved is crucial. Nevertheless, there are certain problem domains in the different phases of emergency management, which may weaken the flow of information. In this paper we present the findings of the first round of a Delphi study in which we identified problem domains in communication both in long-term and short-term planning for major accidents.

Van de Walle (Ed.), Proceedings of ISCRAM 2005 – 2nd International Conference on Information Systems for Crisis Response and Management (pp. 35–41). Brussels: Royal Flemish Academy of Belgium.
Abstract: This paper presents results from a field experiment of IT-use in emergency response work of a fire crew. A prototype has been developed to probe for instances of sensemaking supported by IT-use in such work. The findings have been analyzed in relation to research on design of emergency management information systems and sensemaking theory. Key findings from the field experiment suggest that there is a potential conflict between the role-based emergency management information systems and the shared use of information technology of first responders. Further it is advocated that prototypes should be used to explore the extrinsic of the work practice difficult to uncover using only direct-observation or interviews.

French (Ed.), ISCRAM 2010 – 7th International Conference on Information Systems for Crisis Response and Management: Defining Crisis Management 3.0, Proceedings. Seattle, WA: Information Systems for Crisis Response and Management, ISCRAM.
Abstract: An important aspect of working in an emergency operations center (EOC) is determining what information is credible and what actions to take based on that information. Information during an emergency may come from various sources and EOC workers may not know the information providers personally. Information may come from electronic sources where the exact source of the information may be unknown and credibility may be affected. For this study, we conducted ethnographic interviews with emergency management subject matter experts to gain insights on credibility. The interviews included a series of questions to learn about the current processes of an EOC, what sources generally provide information about the situation and what factors determine credibility. These interviews are ongoing and this paper provides a summary of the interviews completed at this point. The expected outcome of this study is a potential software system with features to enhance credibility despite weak source information.

French (Ed.), ISCRAM 2010 – 7th International Conference on Information Systems for Crisis Response and Management: Defining Crisis Management 3.0, Proceedings. Seattle, WA: Information Systems for Crisis Response and Management, ISCRAM.
Abstract: In this paper we consider how emergency response organizations utilize available social media technologies to communicate with the public in emergencies and to potentially collect valuable information using the public as sources of information on the ground. We discuss the use of public social media tools from the emergency management professionals. viewpoint with a particular focus on the use of Twitter. Little research has investigated Twitter usage in crisis situations from an organizational perspective. This paper contributes to our understanding of organizational innovation, risk communication, and technology adoption by emergency management. An in-depth case study of Public Information Officers of the Los Angeles Fire Department highlights the importance of the information evangelist within emergency management organizations and details the challenges those organizations face with an engagement with social media and Twitter. This article provides insights into practices and challenges of new media implementation for crisis and risk management organizations.

KIT; Baden-Baden: Karlsruher Institut fur Technologie.
Abstract: The growing use of a variety of information systems in crisis management both by non-governmental organizations (NGOs) and emergency management agencies makes the challenges of information sharing and interoperability increasingly important. The use of semantic web technologies is a growing area and is a technology stack specifically suited to these challenges. This paper presents a review of ontologies, vocabularies and taxonomies that are useful in crisis management systems. We identify the different subject areas relevant to crisis management based on a review of the literature. The different ontologies and vocabularies available are analysed in terms of their coverage, design and usability. We also consider the use cases for which they were designed and the degree to which they follow a variety of standards. While providing comprehensive ontologies for the crisis domain is not feasible or desirable there is considerable scope to develop ontologies for the subject areas not currently covered and for the purposes of interoperability.

Landgren (Ed.), ISCRAM 2009 – 6th International Conference on Information Systems for Crisis Response and Management: Boundary Spanning Initiatives and New Perspectives. Gothenburg: Information Systems for Crisis Response and Management, ISCRAM.
Abstract: 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 (EMS) to communicate with collectives like blind or deaf people whom otherwise will be unreachable by usual channels. Moreover, if we consider the constrains imposed by the nature of the emergency situations we can also improve the information transmission to cope with situational disabilities (e.g. smoke during a fire can cause low vision problems). We centered our system architecture on two characteristics: The first one is an ontology that codifies knowledge about accessibility, devices, disabilities, emergencies and media so the alert notification can be tailored according to different parameters; the second one is the use of an open standard like the CAP (Common Alerting Protocol) that enables our system to interoperate with other existing systems.

Washington, DC: Information Systems for Crisis Response and Management, ISCRAM.
Abstract: All phases of emergency management activities – that we will reference hereafter as eResponse activities – depend on data from a variety of sources and involve a range of different organizations and teams at various administrative levels with their own systems and services. The existence of numerous and different actors, policies, procedures, data standards and systems results in coordination problems with respect to data analysis, information delivery and resource management.. In this paper we present a novel approach based on interaction models distributed through a peer to peer infrastructure and we show how it can be applied in the context of crisis management to support coalition formation and process coordination in open environments. In particular, a prototype eResponse simulation system – built on a P2P infrastructure – has been developed to execute interaction models describing common coordination tasks in emergency response domain. Preliminary evaluation of the proposed framework demonstrates its capability to support such eResponse tasks.

Abstract: Correct information is a vital resource during disasters. Without adequate information, response actions may be ineffective. What is the source of information of emergency management systems? Besides that originated from sensors, the emergency team and the public in general, a very relevant source is government data, such as demographic and geographic data, road maps, etc. The heterogeneity of information formats is a well-known problem that affects organizations and communities that want to access public data. Today, most public agencies provide access to their data, but the great majority is unreadable by automated mechanisms. Besides, most of them do not provide a dictionary meaning for the published content. A solution to this problem is of particular importance to emergency response organizations that need access to all information available to better respond to disasters and crisis. The linked open data (LOD) initiative allows the interconnection of data, using standards in the context of the semantic web approach. In ideal conditions, government agencies publish their public data, thus allowing the use of automated data concerned consumers, whether they are other government agencies or citizens. Efforts aimed to link government data are growing in several countries around the world. This talk presents the LOD concepts and describes an architecture that uses LOD in the design of an Emergency Management System. It describes a scheme for collecting available data from government agencies, such as departments of health, transport, works, that can supply information needs during an emergency response operation.

Abstract: This proposal rises from the Center for Disasters Scientific Support experience over eleven years supporting over a hundred disasters in Latin America. It also presents a case study applied to landslides assessments in Teresopolis (Brazil) city, when all field-generated knowledge was still registered in paper and later, at the base station, uploaded to database and finally available for managers evaluation and decision. The proposed methodology creates a platform (still under development) which allows online registration from different field agents during their evaluations enabling data upload combining mobile devices and telecommunication network (or Wi-Fi) technologies. Teams can also customize forms for different information classes (i.e. landslide assessment, rescued person, blocked road) and still retain the possibility to attach images, videos, other files related to each inspection. Incoming data are stored into a web database available for a real-time coordinators evaluation wherever they are (sometimes over a thousand of miles away from disaster area). © 2012 ISCRAM.

Abstract: This paper describes the development of a public emergency messaging system in Western Australia. A set of design criteria were identified by a review of relevant published literature, a survey of current practice in Australia, and consultation with local stakeholders. The system should support: Multiple Recipients, Multiple Channels, Multiple Hazards, Multiple Stakeholders, Multiple Senders, Multiple Platforms, and Write Once Message Composition. A prototype system was built according to these design criteria, based on the Common Alerting Protocol version 1.0. The design was validated in trials simulating messages sent during a tropical cyclone and a bushfire. A total of 56 trial participants from identified stakeholder groups were surveyed with regard to their experience of the prototype system. Overall, the prototype system functioned successfully and participants reported high levels of satisfaction. The paper describes this research project and the initial stages of the subsequent development of a production system, called APECS.
