The increasing number of cyber incidents that critical infrastructures are experimenting is pushing for developing situation awareness systems that exploits geographical data about the network under control. This poster describes the Visual Analytics solution that is under development in the European project PANOPTESEC [6] for monitoring the ACEA (an Italian organization that provides power to ...

Abstract Researchers in science and engineering have a long tradition of collaboration, and increasingly carry out these collaborations across geographical distance. Similar trends exist in industry, where virtual teams are increasing in frequency. While we know that such dispersed collaborations are difficult, there is growing evidence of success. The physical and biological sciences have led ...

In this paper, we present a model of ‘collective innovation’ built upon the network formation formalism. In our model, agents localized on a circle benefit from knowledge flows from other agents with whom they are directly or indirectly connected. They support costs for direct connections which are linearly increasing with geographic distance. The dynamic process of network formation exhibits p...

Recent theoretical work suggests that firm heterogeneity has an impact on the international investment decisions of multinational firms. This paper provides evidence foreign direct investment (FDI) at different levels of aggregation. We use a novel firm-level dataset on the FDI stocks of German firms to assess level and role of heterogeneity. Our data cover the years 1990-2000. We provide evide...

We investigate the antecedents of conflict on collocated as compared with geographically distributed teams. In our field study of 16 collocated and 20 geographically distributed research and development teams, we found little evidence that distributed teams have more conflict. However, we did find that distributed teams experienced more coordination problems and less healthy conflict handling n...

A typical Internet map-server application allows only retrieval of maps and maprelated data. We have been developing web-based GIS/database (WebGD) applications that allow users to insert, query, update, and delete geographical features and the data associated with them from standard Web browsers. The code shared by these applications is organized as the WebGD framework. We have also built a We...

This note revisits the role of migrant social networks as determinants of bilateral-migration flows. We do so using a new database that covers about 190 world countries and features more accurate estimates of bilateral flows than those employed so far. Our battery of gravitymodel exercises show that the impact of social networks is consistent and significant over different specifications, and i...
