Article
The 3N model of radicalization proposes that violent radicalization is the result of the contribution of needs, networks, and narratives. Although research has mainly been supportive of this perspective, a substantial amount of ground remains uncovered regarding the network component of the model. Within this framework, we examine why individuals l...

The self-called Islamic State offered its followers not only a place to die as martyrs, but also a place to be perceived and treated as heroes. The media narrative has tried to appeal to human needs anchored in the search for "honor and glory" as a motivational basis to join the global jihad. In addition, much of its propaganda has tried to inocula...

The present studies examined the hypothesis that loss of personal significance fuels extremism via the need for cognitive closure. Situations of significance loss-those that make one feel ashamed, humiliated, or demeaned-are inconsistent with the desire for a positive self-image, and instill a sense of uncertainty about the self. Consequently, indi...

Over the past few years, the task of conceiving effective attacks to complex networks has arisen as an optimization problem. Attacks are modelled as the process of removing a number k of vertices, from the graph that represents the network, and the goal is to maximise or minimise the value of a predefined metric over the graph. In this work, we pre...
