Since decision making in the face of emotionally laden problems and incomplete information is very difficult, it is useful to develop and test alternative decision methodologies and/or criteria. One approach is to enlarge the system in which the decision is to be made, for example, go from a national system to an international one, as well as to alter the decision criteria. This paper is a heur...

Crisis management is a special type of collaborative approach in which the actors are subject to an uninterrupted stress. It is a quite significant issue because the consequences of crises can bring huge damages (human and economic loses). In order to learn from expertise and reduce consequences, we present in this paper our first results related to the definition of structure and interfaces in...

First Aid Apps enable the public to learn skills that could save their lives and increase their resilience. A comparative review of the adoption of the First Aid App by Red Cross National Societies revealed context specific factors influencing local app engagement. Drawing on these differences, this paper compares engagement in response to critical events in Israel and Malta. Whilst Malta has b...

This paper analyses predictions of a simple model of currency crises in which the peg will be abandoned when the currency overvaluation hits a certain threshold, unknown to the agents. Due to learning about the threshold, some features usually observed in the data and identified with models with multiple equilibria arise in the model. But the model yields distinctive predictions about the behav...

We provide one of the first tests of recent macro global-game crisis models that show that the precision of public signals can coordinate crises (e.g. Angeletos and Werning 2006; Morris and Shin 2002, 2003). In these models, self-fulfilling crises (independent of fundamentals) can occur only when publicly disclosed fundamental signals have high precision; fundamentals are thus the sole driver o...

Thanks to the interdisciplinary nature of crises, the position of researchers in that field is rather difficult. Very often the traditional methods of research cannot be applied there. The article is aimed at the changes in crises research. It describes the substance of individual changes and emphasizes the shift in research approaches to the crisis. Keywords—crisis, change, research

While a crisis requires quick response of emergency management factors, ontology is generally represented in a static manner. Therefore, an adaptive ontology for crisis knowledge representation is needed to assist in coordinating relief efforts in different crisis situations. The paper describes a method of ontology modeling that modifies the ontology in real time during a crisis according to t...
