    Due to the ubiquity and ever-increasing capabilities of cell phones, they have been exploited for mobile data collection in diverse domains [1]. In this position paper, we hypothesize that bystanders can contribute to the handling of emergencies by means of usage of smart phones. To examine our hypothesis, we conducted at first 24 interviews, as described in [2]. Time staggered we also interviewed two persons who experienced the crisis at a stampede [3] at the Love Parade music festival in Germany in the year of 2010. Based on the results of both studies, we draw conclusions for the design of a potential mobile emergency app being dedicated for bystanders.

    Source code is a medium of communication between human developers. Understandability is the key to maintainable and reusable code. Yet code developed collaboratively with weak ownership is a common property resource that su ers from di usion of responsibility, and hence gradual deterioration. Such misbehavior is usually dealt with with strict usage regulations, e.g. coding rules enforced by reviews. Instead, we take for granted a way to privatize code - e.g. based on authorship information obtained from Subversion - and discuss di fferent ways to reward well-mannered coding, while focussing on friendly self-organization and low coercive power in scienti c environments.
