Three main sources: Bent Flyvbjerg should be the main source of information. Flyvbjerg, B. (2006) ‘Five misunderstandings about case study research’, Qualitative Inquiry, vol. 12, no. 2, pp. 219–245. The other two sources should be Hopkins, N., Reicher, S., Khan, S., Tewari, S., Srinivasan, N. and Stevenson, C. et. al (2015) ‘Explaining effervescence: investigating the relationship between shared social identity and positive experience in crowds’, Cognition and Emotion, vol. 30, no. 1, pp. 20–32 and Newburn, T. (2015) ‘Reflections on why riots don’t happen’, Theoretical Criminology, vol. 20, no. 2, pp. 125–44.
