On 22nd September 2020, Professor Robert MacKay, hosted our CECAN Webinar: Trophic Analysis of Directed Networks.
Directed networks are used in many domains. Particularly relevant examples to evaluation and appraisal are systems maps and influence maps. Trophic analysis indicates how far up or downstream each node is and computes a quantity called trophic incoherence, but perhaps better called circularity, which indicates the extent to which the network fails to line up with each node feeding to nodes at the next level. During the webinar, Robert discussed incorporating trophic analysis into systems mapping, and presented relations of trophic incoherence with some other network properties, ending with an application of incomplete pairwise comparison to football leagues.
