Dear DRUID organisers, Thank you for organising such an exciting conference full of good presentations and interesting discussions! I am trying to download my presentation certificate from the website, but I repeatedly get an 'internal server error' message when opening the link. Others colleagues tell me they are having the same issue. I need the certificate to cover the travelling expense at my institution, so I would appreciate if you could provide me with the document. Paper: Negotiating knowledge: the role of network hedging in the production of high-impact science outputs.
