Goods producers in Canada rely on transportation networks to move raw materials and intermediate goods among production sites and finished goods to domestic and international markets. Firms in the retail, tourism and other service sectors also depend on transportation networks to assemble supplies and goods for sale and to bring customers to their facilities. Events that disable parts of the tr...

One question that emerged following the 11 September attacks was how to categorise and classify the event within existing disaster and conflict-event research frameworks. A decade ago, Quarantelli (1993) compared findings on the similarities and differences between consensus- and conflict-type events by illustrating a conceptual distinction between the two. In this paper, this discussion is exp...

As it should, the field of disaster research has always been responsive to real-world events. Each disaster raises new questions, calls attention to shortcomings in the existing knowledge base, and prompts new researchers to enter the field. Thus, historically, progress in understanding disaster effects leaps forward after particularly catastrophic or newsworthy events. The September 11, 2001 t...

T he tragic events of September 11 underscored beyond a shadow of doubt that America is no longer invulnerable to large-scale terrorist attack, and the investigations since conducted into the nature of the threat have unveiled essentially limitless possibilities for more to come. The potential introduction of weapons of mass destruction into such a scenario only furthers the ability of a small ...

Terrorist networks operate in hybrid space where activities in social and geographic spaces are necessary for logistics and security. The Islamist terrorist network is analyzed as a sociospatial system using social network analysis, Geographic Information Science (GISc), and novel techniques designed for hybrid space analyses. This research focuses on identifying distance and sociospatial depen...

Large scale public events are attractive targets for terrorist attacks. It is of great significance to intelligently allocate limited security resources to protect such events. In most public events, the impact of an attack at different targets changes over time. For instance, in marathon, the impact of an attack at different locations changes over time as the participants move along the race c...

armasuisse Science and Technology, the R&D agency for the Swiss Armed Forces, is developing a Social Media Analysis (SMA) system to help detect events such as natural disasters and terrorist activity by analysing Twitter posts. The system currently supports only keyword search, which cannot identify complex events such as ‘politician dying’ or ‘militia terror act’ since the keywords that correc...

The tragic events of September 11th have caused drastic effects on many aspects of society. Academics in the fields of computational and information science have been called upon to help enhance the government’s ability to fight terrorism and other crimes. Keeping in mind the special characteristics of crimes and securityrelated data, data mining techniques can contribute in six areas of resear...
