Dear colleagues,

A quick reminder that you can still submit your abstracts for the 2nd Mobile Apps and Sensors in Surveys (MASS) workshop until Wednesday, Nov 20. See below for details.

Best regards, Florian Keusch

*********** Call for Papers 2nd MASS Workshop Mobile Apps and Sensors in Surveys https://massworkshop.sites.uu.nl/

Organizing committee: Peter Lugtig, Bella Struminskaya (Utrecht University), Jan K. Höhne, Florian Keusch (University of Mannheim)

Date: 23-24 April 2020.

Location: Utrecht University, the Netherlands

Context of the workshop Mobile devices allow researchers to collect data through built-in sensors such as GPS and accelerometers to study movement, passively collect data in-browser, or using apps in addition to self-report. Such data can include browsing history and smartphone and app usage. Passive mobile data collection can potentially decrease measurement errors and reduce respondent burden. Active data collection using apps, camera, microphone, or other sensors allows researchers to broaden the research questions they want to study. Incorporating sensor measurements to augment or replace survey questions through sensors and apps brings challenges for representativeness, survey design and implementation, measurement, as well as ethical and legal considerations that are yet to be understood.

This 2-day workshop is jointly organized by the department of Methods and Statistics of Utrecht University and the Collaborative Research Center: “Political Economy of Reforms” at the University of Mannheim. The workshop itself will be free of charge for participants, but participants are expected to pay for their own travel and hotel costs.

The goal of this workshop is to bring together around 40 researchers from different disciplines to discuss the current state of their work on the use of mobile apps and sensors in survey data collection. The workshop is only open to people who are presenting a paper.

The first MASS workshop was held at the University of Mannheim in March 2019. A programme, as well as some presentations from this workshop can be found at https://massworkshop.sites.uu.nl/2019-workshop-in-mannheim-germany/

For the second MASS workshop, we invite contributions that focus, among others, on the following issues when using mobile apps and sensors in surveys:     Technical aspects of mobile apps and sensors         Different ways to collect sensor data         Building apps for Android and iOS         Data processing and storage     Study and app design         Look and feel of apps         Usability studies         Use of incentives         Giving feedback to respondents     Implementation         Willingness to participate and consent         Methods to invite and communicate with study participants         Study length and study intensity         Legal considerations         Ethical and privacy considerations     Data quality of sensor data         Errors of non-representation (self-selection, coverage, nonparticipation)         Measurement error (prevention, modeling and correction)     Data analysis         Analysing sensor data         Combining survey and sensor data

We encourage submission of work in progress and are particularly interested in studies that used an experimental design to test strategies to collect data using mobile apps and sensors successfully. We are open to both empirical studies as well as descriptions of research data collection infrastructure (front- or backend of an app), or processing of data from apps and sensors.

Submission process and timeline Please submit your abstract (max. 500 words) for the conference to b.struminskaya@uu.nl. The abstract should contain a research question, data collection procedures/the description of the app, and results if available. If results are not available yet, the abstract should outline the type of analyses that will be presented at the workshop.

Participation in the workshop is only possible when an abstract is accepted for the workshop. We intend to keep the workshop limited to about 40 participants.

Timeline: 20 November 2019: Deadline for abstracts submission. 9 December 2019: Feedback on acceptance will be provided. 15 March 2020: Deadline for handout submission - all participants will be required to submit a 6-page handout presenting context, screenshots, tables, or other supporting materials for the workshop. Participants are expected to read all handouts before coming to the workshop.
