Call for unpublished Data: Effort Gains and Effort Losses in Teams

Dear colleagues,

We are currently conducting a meta-analysis on effort gains and effort losses in teams. By now, we have nearly completely coded the published literature.

Now, we are looking for unpublished data. If you have any unpublished data fulfilling the criteria summarized below, we would be very grateful if you could share this data with us. As we would be happy to finish our meta-analysis soon, we would greatly appreciate it if you could do so as soon as possible.

Moreover, we would also very much appreciate any information about recently accepted/published papers that have not been available online before the 1st of September 2019 and that we, therefore, might have missed in our literature search.

Our criteria for inclusion are the following:

* Assessment of effort during teamwork/collective work and during individual/coactive/nominal group work

* Either self-reports or objective measures of effort (i.e., a performance measure)

If you have any unpublished data (including preprints, proceedings, or theses) or recently accepted/published papers fulfilling these criteria, please send your paper and/or dataset to Ann-Kathrin Torka (ann-kathrin.torka@tu-dortmund.de). We also have a word template that you can use to send us the information: https://www.dropbox.com/s/e9b461x0pvr5nqw/Request_and_template_for_unpublished_studies.docx?dl=0

Please choose the format that means the least effort for you - we are of course very grateful to receive your data in any format.

If you have any questions, please do not hesitate to contact us.

Thank you very much in advance for your help! We look forward to hearing from you.

Best regards,

Ann-Kathrin Torka, Jens Mazei, and Joachim Hüffmeier
