Data analysis

All data analyses were carried out using SPSS v. 14.0. Reliability, in the form of internal consistency, was assessed via Cronbach a coefficients (and we also report the lowest item–total correlation obtained for each item). Cronbach a values range between 0 and 1 with values >0.70 typically considered adequate in research contexts. Content validity was assessed via Spearman r correlation coefficients between different core skills as rated by the trainer nurse. Non-parametric coefficients were computed due to small sample size. Medium-sized correlations between skills will provide evidence for adequate content validity. Correlations between trainer and trainees’ ratings across skills were reported as well.

Two different types of data are supported: the archival and the real time data. The archival data stored in spatial and distributed databases, while the real time data comes from sensors. Both data are encoding using the OGC specifications and particularly the Geography Markup Language (GML).Regarding processing, storage and communication aspects, time, space and quality filtering methods are required to be considered in an environmental

management architecture. Time filtering can be implemented using algorithms that remove the temporal data redundancy (through, for example, data dropping mechanisms), while spatial filtering aims at reducing the spatial one (e.g., spatial data down-sampling). Quality filtering automatically re-quantizes the geospatial content to reduce the transmitted information. All these types of filtering are framed with context awareness mechanisms, which proportionally activates one or all of the above three filtering tools according to the type of disaster and environmental conditions.Presentation of data: Apart from a web based user interface, the future environmental information management systems will incorporate (i) 3D rendering and presentation methods (ii) geospatial presentation and (iii) context aware adaptive visualization tools. 3D presentation and real time rendering allows for a better visualization of the natural disaster and therefore yields a more efficient environmental management. Geospatial presentation includes tools for depicted media overlays of geographic enhancements. Finally, context adaptive methods increase the system efficiency, since it permits a differentiated presentation according to either the capabilities of the terminal devices (e.g., PC or PDA) or the requirements of the application scenario.

The concepts, approaches and practices were reviewed and, when deemed necessary, rephrased to ensure that each item provides a brief description of only one factor, is standalone, consolidated, generalisable as much as possible and consistent;( Data was later cleaned, presented, categorized.
