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.

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.

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.

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.

This thesis examines why approximately 700 German foreign fighters traveled to Syria and Iraq between early 2012 and late 2015. It presents the author’s original research on 99 German foreign fighter profiles, examining their preexisting network connections in Germany as well as their biographical availability and integration into German society. The study finds that German foreign fighters are primarily mobilized through traditional social network connections and that the mobilizing network in Germany consists of a nationwide, interconnected, and politically active “Salafist scene.” The project also finds that while Western governments often worry about the looming threat of online radicalization, verifiable examples of purely Internet-based radicalization remain rare.
