Live Studies at REFSQ 2019 Maya Daneva University of Twente, The Netherlands m.daneva@utwente.nl The REFSQ conference has been promoting the application of empirical research methods to the exploration and evaluation of requirements engineering phenomena. As part of this, one of the traditions of the REFSQ conference is the organization of a special plenary session for conducting a “live study” involving the conference attendees on a voluntary basis. A live study could be a (controlled) experiment, a focus group, an interview-based study or an online survey related to requirement engineering. REFSQ 2019 received four submissions for “live studies”. Two independent reviewers reviewed each of the submissions. A sub-committee then prioritized the live study proposals based on various factors and two proposals were selected for inclusion in the conference program:  "Users perceptions on security and satisfaction requirements of context-aware applications: A online questionnaire“ authored by Denisse Muñante and Nelly Condori-Fernandez.  “Assessing the Effect of Learning Styles on Risk Model Comprehensibility: A Controlled Experiment”, authored by Katsiarina Labunets and Nelly Condori-Fernandez . The study authors introduced their study to the REFSQ 2019 attendees and conducted their studies according to their proposed plans. Preliminary results of the two studies will be shared with the REFSQ 2019 participants within the allotted session on Thursday, March 21, 2019. Acknowledgements I am particularly grateful to the REFSQ 2019’s Programme Co-Chairs, Eric Knauss and Michael Goedicke, for including “Live Studies” in the overall REFSQ 2019 programme. I also thank all the members of the Live Study Programme Committee. Finally, we are much indebted to all the volunteer participants in the two studies. It is their expertise and insights into the subject matter that contributes to the authors’s efforts to answer the research questions posed in the two studies.
