Peer-Review Process

The quality of a journal can be determine through the scholarly content it publishes. It is therefore important to define effective and strong peer review process to evaluate the scientific quality of the paper prior to journal publication. Refaad peer-review process ensure that the scholarly manuscripts are evaluated and commented upon by independent experts belonging to the same research interest and area. All our journal editorial and reviewer board members are experts who are dedicated to ensure the validity and originality of journal publications. Refaad peer-review process is based upon single blind review where reviewer's name is concealed from the author(s). In order to ensure that only non plagiarized, original and high quality scholarly research is published, each submitted manuscript first preliminary reviewed by the managing editor to check whether author has provided correct submission information and all supported files with the article.

Steps of Peer-Review Process

  1. Preliminary Review - submitted manuscript go through preliminary review where the appropriateness of the article including research scope within the journal to which it is submitted, quality, format, language, authorship and other information is checked.
  2. Editor-in-Chief assign manuscript to referees to evaluate the technical quality of the scientific research presented in the paper.
  3. Based on the review comments and final decisions made by Editor-in-Chief of acceptance/rejection of the manuscript.
  4. All rejected manuscripts are then permanently closed and authors are informed about the decision.
  5. For accepted papers, authors are then asked to revise manuscript according to reviewers comments and submit the final version within the given time period.
  6. All final submitted papers are then published on www.Refaad.com as soon as they become ready after typesetting and proof reading.
