Van de Walle (Ed.), Proceedings of ISCRAM 2006 – 3rd International Conference on Information Systems for Crisis Response and Management (pp. 197–201). Newark, NJ: Royal Flemish Academy of Belgium.
Abstract: The STATPack is a telemedicine consultation and emergency response system which was developed to increase statewide laboratory responsiveness to public health emergencies. Although several emergency response management information systems have been created for diagnostic laboratories at the national level, most states in the U.S. do not have the capability to share critical public health microbiology laboratory information at local levels, especially in rural communities. This paper offers a description and preliminary assessment of the STATPack as it is being deployed by the Nebraska Public Health Laboratory and should be recognized as research in-progress. Initial experiences with this emergency response system have been encouraging.

Van de Walle (Ed.), Proceedings of ISCRAM 2006 – 3rd International Conference on Information Systems for Crisis Response and Management (pp. 214–222). Newark, NJ: Royal Flemish Academy of Belgium.
Abstract: Crisis response is an information intensive process, which produces or consumes large quantities of information from different relief organizations. Although personalized information retrieval and access has been realized as an efficient means to accelerate information acquisitions, most IT enabled applications in the fields can only provide uniform information to all the involved relief organizations. The traditional centralized design principle dominantly used to address the inter-organizational information accesses over boundaries is no longer feasible due to its lack of flexibility and adaptability to deal with dynamically changing information needs caused by the unpredictable nature of the crises. In this paper we present our ongoing research regarding a plug and play service architecture for personalized, situation aware information retrieval and access services, which offers a new way of thinking about the retrieval of personalized information in the context of crisis response.

B. Van de Walle (Ed.), Proceedings of ISCRAM 2006 – 3rd International Conference on Information Systems for Crisis Response and Management (pp. 121–126). Newark, NJ: Royal Flemish Academy of Belgium.
Abstract: Cooperation and mutual assistance in emergency situations is one of the main objectives of the Latin-American Association of Governmental Organisms of Civil Defense and Protection. To promote such collaboration m-ARCE has been developed; an ubiquitous mobile office for disaster mitigation where users can send and receive information anywhere and anytime. When a catastrophe happens in a country, and almost all infrastructure is destroyed, mobile technology, such as mobile devices and wireless networks, offers the user resources to ask for help and to manage it. Latin-American Countries often suffer catastrophes that provoke numerous human losses and major economic and social problems. International assistance and collaboration with the affected country is necessary to help in its recovery. The Web, like Internet, offers static office services to users who can access information using an infrastructure in indoor environments. On the other hand, mobile computing and networking use the Internet, together with mobile physical devices linked to it, and software platforms built upon it, to design and coordinate systems across countries. In the ubiquitous mobile office design, we describe how services, such as chat, email and wireless communication, should be configured for emergency situation. We make use of ubiquitous hypermedia -linked nodes in ubiquitous spaces- to ensure mobility and accessibility to the mobile device interface, such as PDAs and smartphones.

Van de Walle (Ed.), Proceedings of ISCRAM 2006 – 3rd International Conference on Information Systems for Crisis Response and Management (pp. 504–512). Newark, NJ: Royal Flemish Academy of Belgium.
Abstract: Recent terrorist attacks and natural disasters have forced humanity to respond to crisis situations effectively as possible. In these situations especially the first hours rescue workers cannot always rely on existing communication infrastructure. Knowledge about the situation is to be gathered to obtain an aggregate world model of the situation. Decisions can be taken based on this world model. The solution we propose consists of using a Mobile Ad-Hoc Network (MANET), in which the nodes are organized in a topology in order to facilitate the necessary functionalities. Communication between the nodes takes place via a distributed blackboard structure. This architecture supports services developed with the purpose of assisting rescue workers. The agents (humans/sensors) in the network provide data as input to the network. Our approach takes care of processing of this input data to provide users with appropriate information and to obtain a shared world model. As a proof of concept we implemented a prototype of our approach on a number of mobile devices and tested the idea in real life.

Van de Walle (Ed.), Proceedings of ISCRAM 2006 – 3rd International Conference on Information Systems for Crisis Response and Management (pp. 402–408). Newark, NJ: Royal Flemish Academy of Belgium.
Abstract: A suite of post-earthquake information products and assessment tools are produced and distributed by the U.S. Geological Survey (USGS) National Earthquake Information Center (NEIC). These products range from the rapid determination of earthquake magnitude and location to tools that provide situational awareness following earthquake catastrophes. The NEIC distributes earthquake location, magnitude, and supporting information through many sources including, text message, pager, and the Internet (e-mail, web-pages and RSS feeds). To aid in the rapid determination of an earthquake's impact, the NEIC has developed tools to 1) map the observed shaking intensity reported from the region affected by the earthquake (Community Internet Intensity Maps), and 2) quantify the number of people exposed to severe shaking (Prompt Assessment of Global Earthquakes for Response).

Van de Walle (Ed.), Proceedings of ISCRAM 2006 – 3rd International Conference on Information Systems for Crisis Response and Management (pp. 262–271). Newark, NJ: Royal Flemish Academy of Belgium.
Abstract: The purpose of this paper is to present a model for testing different organizational learning characteristics and their effects on performance rate in times of an unexpected temporary increase in workload. Drawing on the theoretical frameworks of Yerkes-Dodson law, the stress-buffering effect of coping resources, and established crisis management models, the authors examine the hypotheses of curvilinear and interactional influence of single and double-loop learning on stress levels during crises. Using a simulation model, we identify thresholds in single and double-loop learning environments, where increases in workload lead to dysfunctional effects of stress. The findings indicate support for the hypothesis that an organization that employs double-loop learning is less susceptible to negative stress in times of a crisis. Overall, the study highlights the characteristics of different learning types and its effects on stress. It is suggested that experiments with a simulation model lead to a better understanding of how information processing resources that people have access to in stress events, buffers or protects them from negative effects.

Van de Walle (Ed.), Proceedings of ISCRAM 2006 – 3rd International Conference on Information Systems for Crisis Response and Management (pp. 382–385). Newark, NJ: Royal Flemish Academy of Belgium.
Abstract: Information technologies and other critical infrastructures are interconnected in ways that can lead to vulnerabilities in the ability of these infrastructures to perform during natural disasters and acts of terrorism either to reduce adverse consequences or provide needed emergency response services. This research applies and adapts a number of indicators of infrastructure interdependency based on the authors' earlier research to determine where weak points and strengths occur in the interconnections between infrastructure technology and other infrastructure support services such as electric power and transportation, and where weak points create vulnerability that can be improved for more effective response in emergencies.

Abstract: Communication and interoperability between different organizations of first responders has been a problem for a long time. There have been examples of failure in communication between different organizations at World Trade Center on 9/11, for example some of the police warnings were not heard by fire fighters that resulted in several lives lost. In most cases, network unavailability or incapability of coordination among networks causes much damage. Therefore, we present a highly reliable communication infrastructure that is suitable at ground zero where the existing communication network is damaged or unavailable. We used Hybrid Wireless Mesh Network (HWMN) as a candidate for communication infrastructure with the capability of working in a heterogeneous environment with different available backhaul technologies. In addition to the use of WMNs, we also present some special requirements for a cellular networks generated by simulation models investigating different scenarios that occur at ground zero. For example, when hurricane Katrina hit New Orleans, people outside the ground zero area could place a call, but were not able to receive phone calls. This happened because the cellular network elsewhere was not able to contact the Home Location Register (HLR), located at New Orleans. We, in this paper, propose a solution in which the important user or network information databases such as HLR and VLR (Visitor Location Register) are replicated to provide a sufficient amount of fault tolerance.

Van de Walle (Ed.), Proceedings of ISCRAM 2006 – 3rd International Conference on Information Systems for Crisis Response and Management (pp. 82–91). Newark, NJ: Royal Flemish Academy of Belgium.
Abstract: Networking in the event of disasters requires new hybrid wireless architectures such as Wireless Mesh Networks (WMNs). Provisioning Quality of Service (QoS) in such networks which are quickly deployed during emergencies demand radical solutions. In this paper, we provide a new QoS approach for voice calls over a wireless mesh networks during emergency situations. According to our scheme, the contention and back-off parameters are modified based on the emotion content in the voice streams. This paper also looks at methods for detecting emotion from an incoming voice call using the speech signal. The issues of interest in such situations are whether the caller is in a state of extreme panic, moderate panic, or in a normal state of behavior. The communication network behavior should be modified to provide differentiated QoS for calls based on the degree of emotion. We use several features extracted from the speech signal like the range of pitch variation, energy in the critical bark band, range of the first three formant variations, and speaking rate among others to discriminate between the three emotional states. At the back end the Gaussian mixture modeling techniques is used to model the three emotional states of the speaker. Since a large number of features increase the computational complexity and time, a feature selection technique is employed based on the Bhattacharya distance, to select the set of features that give maximum discrimination between the classes. These set of features are employed to simulate an emotion recognition system. The results indicate a promising emotion detection rate for the three emotions. We also present the early results on detecting the emotion content in the speech and using this in the MAC layer differentiated QoS provisioning scheme. Our scheme provides an end-to-end delay performance improvement for panicked calls as high as 60% compared to normal calls.

Van de Walle (Ed.), Proceedings of ISCRAM 2006 – 3rd International Conference on Information Systems for Crisis Response and Management (pp. 592–597). Newark, NJ: Royal Flemish Academy of Belgium.
Abstract: The Automated Remote Triage and Emergency Management Information System (ARTEMIS) project seeks to provide situational awareness to all level of commands in order to increase patient survival rate during emergencies. By moving the burden of triage off of the medic and into an automated system, more time will be able to be spent on casualty care rather than assessment. Continual monitoring of responders and casualties will alert medics of critical changes in a patient's health that might normally have gone undetected after a patient is initially triaged. ARTEMIS employs a network of embedded sensors worn by responders and casualties to gather the data required for greater situational awareness and to relay the data back to appropriate levels of command both on the field and in remote locations.

Abstract: Natural disasters are frequent in Bengladesh. Because Bengladesh has a fragile economy that is mostly dependent on agriculture, these events can be disastrous to the economy and people of the country. Adequate warnings to the community and institutions can mitigate the deleterious effects. This paper presents a model for an effective disaster warning and dissemination system (EWDN) that can provide timely and accurate alerts of natural disasters thus reducing loss of life, property and other risks.

Van de Walle (Ed.), Proceedings of ISCRAM 2006 – 3rd International Conference on Information Systems for Crisis Response and Management (pp. 598–604). Newark, NJ: Royal Flemish Academy of Belgium.
Abstract: Computer-based knowledge management systems are vital for disaster detection, response planning, and management. These systems aid in early warning, and provide decision support for disaster response and recovery management. Managing past knowledge for reuse can expedite the process of disaster response and recovery management. While early warning systems predict some disasters with remarkable accuracy, there is a paucity of knowledge management systems for disaster response and management. This paper outlines a case-based reasoning (CBR) knowledge management system that in effect, is a model of human reasoning since it is based upon the idea that people frequently rely on previous problem-solving experiences when solving new problems. A CBR knowledge management system results in efficient and effective disaster response and management.

Van de Walle (Ed.), Proceedings of ISCRAM 2006 – 3rd International Conference on Information Systems for Crisis Response and Management (pp. 39–49). Newark, NJ: Royal Flemish Academy of Belgium.
Abstract: In order to better understand the challenges specific to the deployment of collaboration technologies in crisis situations, we conducted an informal observational study of the deployment of Groove Virtual Office to various civil and military groups at the heart of the disaster zone over the course of ten days. We summarize both general lessons learned from observations of social and communication challenges in crisis situations that impact technology adoption, and make specific recommendations for improving the deployment process of Groove to enable cross group collaboration. We generally found that dynamic, informal social networks and lightweight ephemeral work groups were essential social structures in the relief effort, and we discuss the need to innovate technologies to support these alternative types of organizations. We encourage that current technology centric innovation for ephemeral workgroups is complemented by a usage centric approach to help address emergent behaviors and opportunities.

Abstract: In managing crises, decision makers are confronted with a plethora of uncertainties. Many arise because the world is uncertain, particularly in the context of a crisis. But some arise because analyses based upon different, but seemingly equivalent models lead to different forecasts. Other times expert advisors differ in their explanations and predictions of the evolving situation. We argue that when handled correctly such conflict can alert the decision makers to the inherent complexity and uncertainty of the situation and improve their management of the crisis.

Van de Walle (Ed.), Proceedings of ISCRAM 2006 – 3rd International Conference on Information Systems for Crisis Response and Management (pp. 147–153). Newark, NJ: Royal Flemish Academy of Belgium.
Abstract: In life-threatening emergencies, citizens need to be warned. The currently used method for citizens warning in The Netherlands is a siren. AT this moment, research is being carried out into using new technologies as an addition to this siren for citizens warning. Modern telecommunication technologies have great potential for informing the public. Especially the use of text-based features of mobile phones is considered for this function. Advantages of such a system are that these technologies overcome problems of hearing the siren and that text-based messages provide possibilities for giving more and more detailed information. In a number of pilot studies, Delft University of Technology has gained experience with the possibilities of these technologies for citizens warning services. This paper compares two text-based mobile phone technologies that can be used for citizens warning as an addition to the siren.

Van de Walle (Ed.), Proceedings of ISCRAM 2006 – 3rd International Conference on Information Systems for Crisis Response and Management (pp. 272–281). Newark, NJ: Royal Flemish Academy of Belgium.
Abstract: The aim of this paper is to describe the I-X system with its principal user interface, the I-X Process Panel, its underlying ontology, , and how this panel can be used as an intelligent to-do list that assists emergency responders in applying pre-defined standard operating procedures in different types of emergencies. In particular, multiple instances of I-X Process Panels can be used as a distributed system to coordinate the efforts of independent emergency responders as well as responders within the same organization. Furthermore, it can be used as an agent wrapper for other software systems such as web services to integrate these into the emergency response team as virtual members. The heart of the I-X system is an automated planner that can be used to synthesize courses of action or explore alternative options manually.

Van de Walle (Ed.), Proceedings of ISCRAM 2006 – 3rd International Conference on Information Systems for Crisis Response and Management (pp. 298–304). Newark, NJ: Royal Flemish Academy of Belgium.
Abstract: The current Emergency Services landscape is characterized by a number of systems and networks that are isolated in nature, thus making information sharing impractical, if not impossible. Such an environment does not promote ease of information sharing, and each incident highlights the need for efficient collaboration and coordination, and the need for a holistic internetwork-a series of virtual interconnected networks-approach. In other words, it requires an overall framework that looks at safety as an overall enterprise, (albeit one with thousands of independent agency owners), with the strategic goal to facilitate greater collaboration and effectiveness of operations, and to ensure a streamlined and efficient prevention of, response to, and recovery from all-hazards. 1 Adopting a Service-Oriented enterprise approach is extremely useful and has number of advantages in such an environment. This paper defines a framework-in the context of an enterprise-an envisioned Emergency Services Enterprise Framework, and identifies the key elements of this framework.

Abstract: The New Jersey Institute of Technology (NJIT) developed an Electronic Disease Reporting & Management System (EDRMS) that has the capability for the rapid collection, analysis, and dissemination of suspected outbreaks including Chemical and Bio-Terrorism events. Prior to EDRMS, agencies relied on dis-jointed phone and fax reporting and rudimentary methods for data collection, dissemination, follow-up, and remuneration. The objective of this system is to allow collaborative recognition across all the hospitals and public health offices in the state of New Jersey to detect as soon as possible an epidemic occurring of a known or unknown type.

Van de Walle (Ed.), Proceedings of ISCRAM 2006 – 3rd International Conference on Information Systems for Crisis Response and Management (pp. 615–624). Newark, NJ: Royal Flemish Academy of Belgium.
Abstract: This paper explores the use of knowledge management with emergency information systems. Two knowledge management systems that were utilized during Hurricane Katrina response are described and analyzed. The systems specified were developed by both federal agencies as well as grass root efforts without the support or mandate of government programs. These programs, although developed independently, were able to share data and interact in life saving capacities, transcending traditional geo-political boundaries. We conclude that emergency information systems are enhanced by incorporating knowledge management tools and concepts.

Van de Walle (Ed.), Proceedings of ISCRAM 2006 – 3rd International Conference on Information Systems for Crisis Response and Management (pp. 282–287). Newark, NJ: Royal Flemish Academy of Belgium.
Abstract: This paper describes the proposed WIPER system. WIPER is intended to provide emergency planners and responders with an integrated system that will help to detect possible emergencies, as well as to suggest and evaluate possible courses of action to deal with the emergency. The system is designed as a multi-agent system using web services and the service oriented architecture. Components of the system for detecting and mitigating emergency situations can be added and removed from the system as the need arises. WIPER is designed to evaluate potential plans of action using a series of GIS enabled Agent-Based simulations that are grounded on realtime data from cell phone network providers. The system relies on the DDDAS concept, the interactive use of partial aggregate and detailed realtime data to continuously update the system and allow emergency planners to stay updated on the situation. The interaction with the system is done using a web-based interface and is composed of several overlaid layers of information, allowing users rich detail and flexibility.

Van de Walle (Ed.), Proceedings of ISCRAM 2006 – 3rd International Conference on Information Systems for Crisis Response and Management (pp. 339–346). Newark, NJ: Royal Flemish Academy of Belgium.
Abstract: Disaster Risk Management (DRM) is a multi-dimensional problem complex requiring knowledge and experience from a wide range of disciplines. It also requires a methodology which can collate and organize this knowledge in an effective, transparent manner. Towards this end, seven specialists from the social, natural and engineering sciences collaborated in a facilitated workshop in order to develop a prototype multi-hazard disaster reduction model. The model, developed with computer-Aided morphological analysis (MA), makes it possible to identify and compare risk reduction strategies, and preparedness and mitigation measures, for different types of hazards. Due to time constraints, the model is neither complete nor accurate-but only represents a proof-of-principle. The workshop was sponsored by the Earthquake Disaster Mitigation Research Center (EDM) in Kobe, in January, 2005.

Van de Walle (Ed.), Proceedings of ISCRAM 2006 – 3rd International Conference on Information Systems for Crisis Response and Management (pp. 72–81). Newark, NJ: Royal Flemish Academy of Belgium.
Abstract: Works on Emergency Response Systems (ERS) tend to set aside-or discuss peripherally-the global nature of catastrophes and the unique conditions under which these systems have to operate. Major disasters either affect more than one country or require the help of more than one nation. Designing ERS to manage global crisis situations pose great challenges due to incompatible technologies, language and cultural differences, variations in knowledge-level and management styles of decision makers, and resource limitations in individual countries. In this paper, we outline theoretical foundations for designing global ERS. We develop a path model that identifies the elements and their interactions needed to ensure quality of outcomes and processes of emergency response. We also prescribe a Global Information Network (GIN) architecture to provide decision-makers with timely response to crises involving global intervention.

Van de Walle (Ed.), Proceedings of ISCRAM 2006 – 3rd International Conference on Information Systems for Crisis Response and Management (pp. 17–23). Newark, NJ: Royal Flemish Academy of Belgium.
Abstract: Disasters in Earth Nature Systems (in river basins and in coastal zone) are generated the systems by influence under pressure and impacts of external systems. The water related disasters include the most of hazardous processes on land and sea as follows: floods, avalanches, droughts, landslides, debris-flows, erosion, abrasion, and others. The external systems are not yet able to let know about the Time, Place, and Power of future disasters all together. However, Earth systems allow doing it because of their property to delay on exterior power. The proposed and discussed is the Moving Digital Earth (MDE) technology for outstripping estimation of the Earth Nature Systems response on exterior pressure and impacts. The MDE uses only the knowledge of current System's state and methods of the Digital Systems Analysis (DSA) by high-speed computing.

Abstract: Crisis detection can help enterprises to make full preparation to respond real crisis, so it is an important field to promote enterprises' competition and keep them develop continuously. Crisis in enterprises may be caused by many factors and most of them are very common and necessary parts in normal operating procedure. This paper takes these parts as crisis signals indicated in many managing books. Group decision-making strategy is put forward to help enterprises to analyze crisis signals based on the characteristics of the decision-making procedure. To get a meaningful and credible result, AHP is used to support the whole procedure. To exhibit the role of managers, system cluster is used to classify experts involved in decision-making procedure. An example to analyze a key engineer's dismissing is given to illustrate the decision-making procedure and to prove the efficiency of this idea and AHP method.
