- Comparing complex networks: An application to emergency managers mental modelsPublication . Caseiro, Nuno; Trigo, PauloThis paper describes an exploratory work that aims to identify a semantic basis underlying a mental model from the field of emergency management using a collaborative approach. An experimental application of the distance ratio measure was used to compare individual networks among themselves and to analyze the aggregated network representing the group mental model. The data was obtained by surveying a group of Civil Protection graduates and aggregating all the answers (shared mental model). The data allowed us to deepen the analysis of the resulting network in order to understand the main group concepts and their relations within this domain.

- Emergency management concepts: A network approachPublication . Caseiro, Nuno; Trigo, PauloThe socio-technical systems that make part of our lives are subject to disturbances through disasters that can have serious consequences (at the limit, completely destabilizing the basis system). To deal with this situation modern societies have developed structures, tools and mechanisms that aim to reduce the probability of occurrence of these negative situations. Good decision making is critical and information is needed when analyzing the environment for risks, when defining emergency plans, when training agents and society to deal with the foreseen accidents. All elements and people involved in the emergency cycle phases need to have a common mental structure to deal with information issues. The present work is an exploratory study that aims to identify a semantic base underlying the mental model from the field of emergency management, using a collaborative approach to build it. Mental models, underlie how people structure concepts; how they relate them; what concepts they recall first and which concepts they associate with them. We use a group Civil protection graduates to verify the suitability of the proposed methodology. This approach merges both the power of collaborative techniques and the use of social sciences methods to obtain the data that will allow to build a network of concepts that represents the participants’ mental models. The data obtained, by aggregating all the answers, allow us to deepen the analysis of the resulting network, to understand connections and main group concepts in this domain. Some of the questions we want to answer are: (1) type and intensity of the relations defined; (2) network coherence, by searching missing key nodes or relations.
