We strive to ensure that every article is published in a timely manner. However, there is simply too much variability in the submission process, such as the willingness of reviewers to evaluate a paper on a particular topic, for us to guarantee a specific timeframe for article publication. We do, however, publish journal articles online first, as soon as they’re ready, with a full citation. Complete issues follow at regular intervals.
No, we can’t accept article that have been previously published in other journal. However, we do understand that many submission many be evolutions of previously published works. For this reason, we allow submission to consist of no more than 15% previously published work
