Reviewing procedure

Each paper will be assigned by Professor K. L. Teo, the Editor-in-Chief (EiC), to a Managing Editor (ME). The EiC and the ME will reject the paper if they do not think that the paper should enter into the formal reviewing process. The ME will assign the paper to an Associate Editor (AE) and the AE will make a decision as to whether or not the paper should be sent out for external review. If not, the AE will write a short note rejecting the paper and send it to the ME. Otherwise, the AE will contact three or more potential referees for the paper directly with the request of a report within three months. Once the AE has collected two or more reports, the AE will provide the ME with a final assessment of the paper's quality and a recommendation (accept, minor revision, major revision, reject). NACO will then communicate the final decision to authors. In the case of a major revision, papers will undergo a second round of review with a similar procedure. When the paper is finally accepted, the EiC will send the formal acceptance letter to the corresponding author.
