From the abstract:

The present dissertation explores the collective identity of the Anonymous movement. This movement is characterised by the heterogeneity of its activities, from meme-crafting to pranks to activist actions, with a wide range of goals and tactics. Such heterogeneity raises the question as to why such a diverse group of people makes the decision to act under the same name. To answer this question, the concept of collective identity is applied, which describes how participants collectively construct the definition of their group.
