From the Journal of World Philosophies Facebook page:

Professor Nathan Sivin (Pennsylvania) would like to engage with the journal’s readers on the topic ‘Why Some Comparisons Make More Difference than Others’. We invite readers to submit their own short takes on the topic via the OJS site by 15 January 2017. Together with Professor Sivin, the journal’s editorial team will select about 4 respondents on the basis of the submitted abstracts. Abstracts should not exceed more than 250 words. They should include a title, 5-8 keywords, and a short bio.
