Do journals have a publication bias?

The timely publication of accurate and unbiased results of research is necessary to ensure that the knowledge gained is effectively shared with both the scientific community and the public. The ability to publish will be dependent not only on the significance of the findings, but also on the editorial staff of the journal and the peer review process. The manner in which the peer review process can be influenced by a journal's staff, as well as by the potential bias of reviewers, needs appreciation. Additionally, the routine practice of a journal providing copies of articles and press releases related to those articles in advance of the journal's publication and general availability requires evaluation.
