Still following the post above check the recent paper below:
"The
current peer review system is under stress from ever-increasing numbers of
publications, the proliferation of open-access journals and an apparent
difficulty in obtaining high-quality reviews in due time. At its core, this
issue may be caused by scientists insufficiently prioritising reviewing.
Perhaps this low prioritisation is due to a lack of understanding on how many
reviews need to be conducted by researchers to balance the peer review
process."
