"Using millions of messages sent in Twitch chatrooms, we explore the effectiveness of methods for encouraging and discouraging specific behaviors, including
taking advantage of imitation effects through setting positive examples and using moderation tools to discourage antisocial behaviors. Consistent with aspects of imitation
theory and deterrence theory, users imitated examples of behavior that they saw, and more so for behaviors from high status users. Proactive moderation tools, such as chat modes which restricted the ability to post certain content,
proved effective at discouraging spam behaviors, while reactive bans were able to discourage a wider variety of behaviors."

"In this paper we explore audience participation games, a type of game that draws spectators into a role where they can impact gameplay in meaningful ways. "To better
understand this design space, we developed several versions of two prototype games as design probes. We livestreamed them to an online audience in order to develop
a framework for audience motivations and participation styles, to explore ways in which mechanics can affect audience members’ sense of agency, and to identify promising
design spaces. Our results show the breadth of opportunities and challenges that designers face in creating engaging Audience

"In this paper, we explore some of the traditional domains of social identity theory, discuss some of the newer extensions of social identity theory, and talk both
about how a deeper understanding of social identity theory can benefit CSCW research and how, in return, CSCW can contribute new insights and directions for
extending social identity theory."
"Users are drawn to anonymous apps because of the appeal of the protection provided by anonymity or partial disclosure of identifying information. Partial or complete
anonymity supports identity exploration and social boundary management but presents challenges in discerning user sincerity and expertise through
conventional signals. This project focuses on understanding how users evaluate the posts of others in an anonymous and ephemeral setting on the mobile anonymous mobile posting app Yik Yak."
