Abstract: This paper introduces two concepts-dialogical emergency management and strategic awareness-as means to use and understand the content of social media for the purpose of emergency communication. Dialogical emergency management denotes that the emergency management organizations follow what people publish in various social media on emergencies and ongoing emergency response, and then adjust their information strategies in a way that matches the expectations and needs for emergency information of the public. The concept of strategic awareness suggests that it is essential to have an understanding of the receiver (public) of emergency information but also to have an understanding of the receivers' idea about the emergency and emergency response. Hence, the notion of strategic awareness incorporates structured awareness of how people interpret, value, and reacts on communication based on what they think about the sender's (emergency management organization's) actual intentions and motives.

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: Today emergencies seem more complex than ever. Process of managing these emergencies also becomes more complex because of increasing number of involved parties, increasing number of people affected, and increasing amount of resources. This complexity, inherent in emergency management, brings lots of challenges to decision makers and emergency responders. Information systems and technologies are utilized in different areas of emergency management. However complexity increases exponentially in emergency situations and it requires more sophisticated IS and IT and it makes response and management more challenging. Thus analyzing the root causes of emergency management information systems complexity is crucial for improving emergency response effectiveness. This paper frames the issue of information systems complexity by focusing on the types of complexities involved in emergency management phases and explaining each complexity type. We propose 6 different complexity types: Human Complexity, Technologic Complexity, Event Complexity, Interaction Complexity, Decision Making Complexity, and Cultural Complexity.

Abstract: As part of ongoing research into optimizing the response to large-scale emergencies, an agent-based simulation (ABS) is being developed to evaluate different rescue plans in silico. During the development of this software, decisions regarding its design have been required in order to best satisfy the following specific application requirements: (1) the construction of a sufficiently detailed virtual environment, representing a real geographical area; (2) the programming of a wide variety of agent behaviors using a minimal amount of code; (3) the computational handling of the “large-scale” nature of the emergency; and (4) the presentation of a highly visual user interface, to encourage and facilitate use of the software by practitioners involved in the project. This paper discusses the decisions made in each of these areas, including the novel use of policy-based class design to efficiently program agents. Future developments planned for the software are also outlined.

Abstract: Emergency situations are chaotic in nature. It is however, necessary to understand the context in which Emergency Responders work such that information practice issues can be highlighted and addressed by the system designers. In this paper, Activity Theory is proposed as a methodological and analytical framework to study information practices in the context of Emergency Management. Activity Theory aids in achieving a holistic approach to understanding the work activities context unlike some other analytical methodologies, as it focuses on use of artifacts for the interaction of humans with their environment. In this paper, an activity system model is used to investigate information practice issues of response phase of the emergency services in the UK. Using Activity Theory as an analytical framework, several tensions and contradictions emerged which keep the system unstable but which are also a source of innovation. It is also argued that Activity Theory can usefully be applied to the analysis of information practices over short period of time.

Abstract: Small-scale unmanned aerial vehicles (UAVs) have recently gained a lot of interest for various applications such as surveillance, environmental monitoring and emergency response operations. These battery-powered and easy-to-steer aerial robots are equipped with cameras and can promptly acquire aerial images. In this paper we describe our system of multiple UAVs that are able to fly autonomously over an area of interest and generate an overview image of that area. Intuitive and easy user interaction is a key property of our system: The user specifies the area of interest on an electronic map. The flight routes for the UAVs are automatically computed from this specification and the generated overview is presented in a Google-Earth like user interface. We have tested and demonstrated our multi-UAV system on a large fire service drill. Our system provided a high-resolution overview image of the 5.5 ha large test site with regular updates, proved that it is easy to handle, fast to deploy, and useful for the firefighters.

Abstract: Speed is a central value for emergency logistics stakeholders. Emergency response literature makes a compelling case for rapid logistics processes to provide goods and services in humanitarian emergencies. However, speed is not well-defined concept. While situational demand contributes to the need for speed, an important factor is the perception of speed given the experience of the response stakeholders. Unfortunately, the literature lacks complex, situated pictures of how logistics stakeholders experience speed (i.e., what does it mean for a logistics process to be “fast”? What factors affect whether stakeholders perceive a logistics experience as fast?) To address this gap, we explored how logistics stakeholders in a large international humanitarian organization experience and perceive speed of operations. Our findings suggest that (1) the experience of speed is often comparative, not solely objective; (2) close communication between internal clients (field requestors) and service providers (logistics team) can make clients more likely to experience the logistics process as fast; and (3) feeling in control of decision-making can make both clients and service providers more likely to experience the logistics process as fast.

Abstract: Understanding the performance of disaster monitoring systems is a key to understanding their success, therefore; various qualitative and quantitative measures and metrics can be applied in the characterization and analysis of such systems. Through evaluation studies, problems that impede a disaster monitoring system performance can be identified. The results can be used for system control, design, and capacity planning. Previous studies address technical performance analysis metrics for analyzing monitoring systems leaving out human and organizational dimensions of such systems. Thus, the primary objective of this study is to identify and describe a set of disaster monitoring systems performance analysis metrics that may be employed to evaluate such systems. This study may be valuable to researchers and practitioners involved in disaster and emergency response studies in planning the transportation of vital first-aid supplies and emergency personnel to disaster-affected areas, and in improving chances of survival after a natural disaster.

Abstract: The “walking wounded” is a category of disaster victims that can help themselves in finding their way to safety. The problem we address here is how first responders, walking wounded, and other rescue personnel can coordinate their joint activities more efficiently in order to accomplish the evacuation as quickly as possible. We focus our design on the “coordination loops” in the disaster response organization, both vertically across levels of authority, and horizontally among responders in the same echelon. In our envisioned scenario of a chemical accident we identify the most important interactions through which activities are coordinated that are crucial for a successful evacuation. We propose three different “coordination devices” that can be used by the walking wounded, the rescuers in the fields, and the people in the command center. We believe our approach, explicitly designing support systems for coordination first, will lead to important improvements in the daily practice of disaster response.

Abstract: This paper tests the claimed benefits of using geographical information systems (GIS) in emergency response operations. An experimental study comparing command teams using GIS and paper-based maps is presented. The study utilized a combined approach using microworld simulations together with physical artefacts. Participants in the experiment took the role of command teams, facing the task of extinguishing a simulated forest fire. A total of 132 persons, forming 22 teams, participated in the study. In eleven of the teams, the participants were given access to GIS with positioning of fire-brigades as well as sensor data about the fire outbreak. In the other eleven teams, the participants were using paper-based maps. The result shows that teams using GIS performed significantly better than teams with paper-based maps in terms of saved area. Communication volume was considerably reduced in the case of GIS teams. Implications of these results on GIS are discussed as well as methodological considerations for future research.

Abstract: Group-oriented services including data dissemination, group calls and real-time video transmission are considered as an important application in public safety communications. The main interest is in one-way real-time video transmission from the hot spot to multiple recipients. This is important for efficient emergency response. The changing topology of the multi-hop communication links in a public safety environment makes routing and multicasting extremely challenging task. The purpose of this paper is to study the performance of wireless mobile ad-hoc networks with one-way multicast video traffic. To consider a realistic public safety scenario, the effect of extensive unidirectional links is investigated. The system performance study of various ad-hoc network configurations is done by simulations. For wireless multicast routing, the On Demand Multicast Routing Protocol is used. The performance results are compared with the requirements provided by Statement of Requirement document of standardization project MESA.

Abstract: Making sense of the current state of an emergency and of the response to it is vital if appropriate decisions are to be made. This task involves the acquisition, interpretation and management of information. In this paper we present an integrated system that applies recent ideas and technologies from the fields of Artificial Intelligence and semantic web research to support sense-and decision-making at the tactical response level, and demonstrate it with reference to a hypothetical large-scale emergency scenario. We offer no end-user evaluation of this system; rather, we intend that it should serve as a visionary demonstration of the potential of these technologies for emergency response.

Abstract: In an extreme event or major disaster, very often there are both alternative actions that might be considered and far more requests for actions than can be executed immediately. The relative desirability of each option for action could be a collaborative expression of a significant number of emergency managers and experts trying to manage the most desirable alternatives at any given time, in real time. Delphi characteristics can satisfy these needs given that anyone can vote or change their vote on any two options, and voting and scaling are used to promote a group understanding. Further utilized with Thurstone's Law of Comparative Judgment, a group decision or the range of acceptability a group is willing to consent to, can be calculated and utilized as a means of producing the best decision. A ubiquitous system for expeditious real-time decision making by large virtual teams in emergency response environments is described.
