“Given that peer review is the most valuable asset of journals, we would like to urge again our referees, in an even stronger manner, to be as rigorous as possible when reviewing our submissions. We understand that this task will require an even greater effort by reviewers and we therefore feel that this should be rewarded in some way. Hence, in the spirit that scientific work should be remunerated, we have decided to allocate funds for this purpose and to pay a token fee for every referee report beginning in 2008. We strongly feel that this new practice in the policy of scientific journals is the right step on the way to further improve the quality of our peer review process.”
