    The Role of Social Media during Social Movements – Observations from the #metoo Debate on Twitter
    ( 2020-01-07) Brünker, Felix ; Wischnewski, Magdalena ; Mirbabaie, Milad ; Meinert, Judith
    In recent years, the development of information communication technologies (ICT) such as social media changed the way people communicate and engage in social movements. While conventional movements were fought in the streets, social media enabled movements to take place online. In this paper, we aim to investigate the role of social media during social movements which evolve online. Specifically, we examined Twitter communication during the #metoo debate. To this end, we applied methods from social network analysis to identify influential users participating during the debate. Conducting a manual content analysis, we classified 200 power users into roles. Likewise, a manual classification of 1,271 tweets found distinct communication categories. The results overall point to different motives: First, the communication was deeply concerned with the issue of sexual harassment, calling for attention and action. Second, we found reason to believe that self-serving and branding intentions drove participation.

    Effects of Stigmergic and Explicit Coordination on Wikipedia Article Quality
    ( 2020-01-07) Crowston, Kevin ; Rezgui, Amira
    Prior research on Wikipedia has noted the importance of both explicit coordination of edits (i.e., through the article Talk page) and stigmergic coordination (i.e., through the article itself). Using a panel data set of article quality and edits for 23 articles over time, we examine the impact of different kinds of edits on article quality. We find that stigmergically-coordinated edits seem to have the biggest effect on quality, but that explicit coordination of major edits also predicts article quality. The findings have implications for both research on coordination in Wikipedia and for supporting editors
