I am Steve Marson, the senior editor of the journal. I want to explain how to assess in a conceptual framework. Most people think of a conceptual framework as a theory. Here, we need to assess if the manuscript is tied together with a unifying idea. If the manuscript includes fragments of ideas, the presentation has a weak conceptual framework. Such a presentation is easy to identify and should receive a low score on this measure (i.e zero). Manuscripts that have a clear conceptual frame should receive a score of 5. The most difficult manuscripts are those that fall in the middle. Here the reviewers must use their best professional judgment for scoring.
