CECAN Webinar - Trophic Analysis of Directed Networks



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.


Helping Health Services Plan for Covid-19



Between March and July 2020 Brian Castellani and Pete Barbrook-Johnson became part of the COVID-19 Community Health and Social Care Modelling Team at Durham University. The team was led by Dr Camila Caiado and Professor Brian Castellani, with the purpose of creating a series of modelling tools that Trusts and Councils in the North East of England could use to help support decisions and planning accordingly. Castellani and Barbrook-Johnson were particularly involved in developing two models.


Policy Internship – Abandoned, Lost and Discarded Fishing Gear – A fisherman’s perspective

Policy Internship


From April - June 2019, Betheney Wills, a PhD Researcher from CECAN/University of Surrey undertook a policy internship with the Marine and Fisheries Team at the Department for the Environment Food and Rural Affairs (Defra). The aim of the internship was to gain a better understanding of fishermen’s perspectives on Abandoned Lost and Discarded Fishing Gear (ALDFG) in the seas around the UK. Betheney's final report has now been published by Defra, and can be accessed here.
