More than 90 papers and applications for the Brand Science Slam have already been submitted for the GBC 2019. But almost as many inquiries came as to whether an extension of the submission deadline would be possible. We want the best ideas and research pieces. Therefore, the conference team decided to extend the deadline by ten days. The final deadline is now 15 November 2018, but no further extension is possible as we want to notify all authors by 17 December and the review and decision process will take some time.
