Human aspects, gamification, and social media in collaborative software engineering

Software engineering is inherently a collaborative venture. In open-source software (OSS) development, such collaborations almost always span geographies and cultures. Because of the decentralised and self-directed nature of OSS as well as the social diversity inherent to OSS communities, the success of an OSS project depends to a large extent on the social aspects of distributed collaboration and achieving coordination over distance. The goal of this dissertation research is to raise our understanding of how human aspects (e.g., gender or cultural diversity), gamification and social media (e.g., participation in social environments such as Stack Overflow or GitHub) impact distributed collaboration in OSS.
