Capitalizing on the Koran to fuel online violent radicalization: A taxonomy of Koranic references in ISIS’s Dabiq

The current study set out to investigate to what extent ISIS is bolstering its jihadist ideology on a ‘cut-and-paste’ or ‘cherry-picked’ version of Islam in their renowned online propaganda magazine Dabiq. The main objective was to examine in a systematic and quantitative way to what extent ISIS utilizes the Koran in an atomistic, truncated and tailored manner to bolster its religious legitimacy. A total of 15 issues of Dabiq and 700 Koranic references were scrutinized. By means of a quantitative analysis we developed an innovative taxonomy of Koranic chapters and verses (i.e. surahs and ayat, respectively) on the basis of their appearance in Dabiq. Our large-scale data analysis provide consistent empirical evidence for severe decontextualization practices of the Koran in three ways: (1) a thin, Medinan-dominated religious layer, (2) ayah mutilation, and (3) clustered versus exclusive mentions. Limitations and implications for future research, policy makers and CVE initiatives are discussed.

Visual audience gatekeeping on social media platforms: A critical investigation on visual information diffusion before and during the Russo–Ukrainian War

Gatekeepers, including prerogative elites and institutions, possess multifaceted tools for controlling information. Historically, these gatekeepers have systematically instrumentalized visual information to shape audience perceptions in alignment with specific agendas. However, the advent of social media platforms has disrupted these power dynamics, empowering audiences through user-driven visual information exchanges. This has led to visual audience gatekeeping whereby users act as audience gatekeepers by selectively disseminating visual content, thus shaping information diffusion. While this democratisation of gatekeeping holds considerable promise for user empowerment, it also presents risks. These risks stem from the inherently persuasive yet manipulative qualities of visual content, compounded by users' susceptibility to unconscious biases, especially during polarising events. Therefore, we critically investigated visual audience gatekeeping in the context of the Russo–Ukrainian War, specifically focusing on a Reddit subforum devoted to Russia-related discussions. We find that visual audience gatekeeping operates within a paradigm that reflects the social reality the audience embraces. Audience gatekeepers disseminate visual information both to reproduce and defend an idealised conception of this social reality. Collectively, they produce a visual echo chamber characterised by low information diversity, which, in turn, reinforces and perpetuates the incumbent paradigm. However, heightened social tensions can trigger a paradigm shift and amplify the reproduction and defence processes, increasing the potential for the diffusion of more radical and extreme visual narratives. Based on our findings, we propose a theoretical model of visual audience gatekeeping, which has important implications for research on visuals, gatekeeping and social media platforms.

Identity and politicization among Turkish migrants in Germany: The role of dual identification.

The article examines the role of collective identification processes in the politicization of Turkish migrants in Germany. Building on the suggestion that politicized collective identity is a dual identity, the authors predicted and found that dual identification as both Turkish and German was positively related to politicization among members of the Turkish minority in Germany. This relationship was found in both cross-sectional and longitudinal analyses and held up even when the influence of sociodemographic variables, past political activity, and other forms of collective identification were statistically controlled, suggesting a unique and causal role of dual identification. However, there was no evidence that dual identification fosters radicalization or even political violence. The implications for social integration of politicization driven by dual identification are discussed, as is the interplay of dual identification and separatist identification that could underlie the shift from involvement in normative politics to radicalization.

辐照对Provolone干酪化学成分和质构的影响

采用不同剂量的60Co-γ射线对Provolone干酪进行辐照处理,研究了辐照杀菌的干酪在储藏期间化学成分与质构的变化。结果表明:(1)储藏期间,随着辐照剂量的增加,辐照干酪的Aw呈降低趋势,辐照吸收剂量越大,Aw下降的程度也越强;酸价、过氧化值和TBA值明显增加;(2)储藏期间,随着辐照剂量的增加,pH4.6 SN和12%TCA SN的质量分数都呈下降趋势;辐照干酪的TPA硬度、弹性和凝聚性都呈下降趋势;(3)根据电泳图可知,Provolone干酪随着辐照剂量的增加,酪蛋白的水解程度降低,在副κ-CN以下的小分子量的快速迁移肽含量有明显的减少,而β-CN和副κ-CN之间的大分子量的迁移肽减少不明显。
