For q = 2e, e ≥ 4, the Subiaco construction introduced in [2] provides one q–clan, one flock, and for e 6≡ 2 (mod 4), one oval in PG(2, q). When e ≡ 2 (mod 4), there are two inequivalent ovals. The associated generalised quadrangle of order (q, q) has a complete automorphism group G of order 2e(q − 1)q. For each Subiaco oval O there is a group of collineations of PG(2, q) induced by a subgroup ...

In the last decade’s media discourse, particular Arab immigrant groups received name ‘Arab clans’ and have been portrayed as criminal kinship networks irrespective of actual involvement in crime. We question how are categorized, criminalized, racialized German media. To answer this question, we collected clan-related mainstream articles published between 2010 2020. Our first-step quantitative t...

An agent-based model conflict between herdsmen in east Africa using the MASON agent-based simulation environment is presented. Herders struggle to keep their herds fed and watered in a GIS-based, spatially diverse environment with data-driven seasonal cycles. The model produces realistic carrying capacity dynamics and basically plausible conflict dynamics. With the rather basic set of behaviors...

Software ecosystem platforms such as Google’s Play Store or Apple’s App Store rely heavily on highly motivated third-party developers who are eager to invest their time and effort into developing and updating apps for platforms. Platform owners are challenged to find a balance between developers’ need for autonomy and a platform’s integrity. Despite the widely acknowledged importance of informa...
