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 present a broad distribution of heterogeneity-dependent aggregation mechanisms centered around homophily. The good agreement between the theory and empirical data suggests that existing strategies aiming to defeat online extremism under the assumption that it is driven by a few “bad apples” are misguided. More generally, this generalized theory should apply to a range of real-world systems featuring aggregation among heterogeneous objects.

The association between 4chan and online extremist subcultures has seen increasing academic scrutiny—particularly following the 2019 Christchurch attack by a right-wing terrorist who frequented the anonymous forums. Gender-based extremism features as one (of many) critical subcultures that commands our academic attention, though few studies to date have sought to capture and assess the entire landscape of this phenomenon on 4chan’s most notorious board: /pol/. Drawing on a pre-Christchurch attack dataset extracted from Papasavva et al. (2020), this study investigates how Australians and New Zealanders (ANZ) broadly conceptualize—and debate—women, gender, and sexual violence on 4chan’s /pol/ board. We apply a mixed-methods approach, combining automated machine learning tools alongside expert qualitative analysis. Across nearly 300,000 posts and comments, we show how gender is constructed within this community, and the conjugal order they demand as a result. This order racially and sexually defines gender identities and norms, which are perceived as mechanisms to restore power and dominance to an ethnically and ideologically conforming in-group. Those that violate or disrupt the conjugal order are legitimized as targets of sexual, and gender-based violence. This normalizes far/extreme right gendered constructs across ANZ contexts in support of exclusivist far/extreme right ideological positions.

New communication technologies are often invested with users’ hopes for change in the social order. Thus the Internet is said to be inherently democratic, levelling traditional distinctions of social status, and creating opportunities for less powerful individuals and groups to participate on a par with members of more powerful groups. Specifically, the Internet has been claimed to lead to greater gender equality, with women, as the socially, politically, and economically less powerful gender, especially likely to reap its benefits.

There are many computer programs that model the consequences to built infrastructure when subject to explosive blast loads; however, the majority of these do not account for the uncertainties associated with system response or blast loading. This paper describes new software – called “Blast-RF” (Blast Risks for Facades) – that incorporates existing blast-response software within an environment that considers threat/vulnerability uncertainties and variability via probability and structural reliability theory. This allows the prediction of likelihood and extent of damage and/or casualties; information which will be useful for risk mitigation considerations, emergency service’s contingency and response planning, collateral damage estimation and post-blast forensic analysis.

The Global Counterterrorism Forum published this report to compile a non-exhaustive list of governmental good practices regarding strategic communications and social media aspects in preventing and countering violent extremism and terrorism online for GCTF Members – as well as any other interested Government. The good practices expressed in this document were identified in meetings and subsequent discussions with GCTF Members, reflecting their experience in this regard. Moreover, with these recommendations, the GCTF aims to support and complement existing work and initiatives by other international and regional organisations, namely the UN and other relevant stakeholders involved in this context. The good practices are divided into three sections: Section I addresses overarching good practices for preventing and countering violent extremism and terrorism online; Section II addresses good practices for content-based responses; and Section III addresses good practices for communications-based responses.
