We introduce a generalized form of gelation theory that incorporates individual heterogeneity and show that it can explain the asynchronous, sudden appearance and growth of online extremist groups supporting ISIS (so-called Islamic State) that emerged globally post-2014. The theory predicts how heterogeneity impacts their onset times and growth profiles and suggests that online extremist groups ...

This article contributes to public and policy debates on the value of social media disruption activity with respect to terrorist material. In particular, it explores aggressive account and content takedown, with the aim of accurately measuring this activity and its impacts. The major emphasis of the analysis is the so-called Islamic State (IS) and disruption ...

Daesh’s centralized media operations provide a steady stream of media products to citizens living in and around its controlled territories, with the result that several nations occupied or adjacent to the group have emerged as many of the most fruitful recruiting grounds for new members.

These themes have been present in a number of studies that have examined consumption of the dark dystopic variety. We seek to elucidate ...

These capabilities have been particularly targeted toward terrorism suspects and organizations that have been observed using the Internet for communication, propaganda, research, planning, publicity, fundraising and ...

We examined whether and how social media play a role in the process of radicalization, and whether and for what purposes extremists use social media after they become radicalized within a sample of fifty-one Canadian extremists. Differences between converts and non-converts in terms of their radicalization process, involvement in terrorism, and social media usage were ...

This is the third and final research review in the CREST series on ideological transmission (the first was on the family, and the second on peers, education and prisons). It focuses on the process by which religious and political groups – from small cells and organisations to large movements, networks and milieus – pass on ...
