Journal editors are looking for submissions that effectively disseminate research findings relevant to their readers. They evaluate submissions based on criteria such as the significance of the topic, how the work adds to existing knowledge, the rigor of the argument and evidence, and the clarity and structure of the presentation. The peer review process involves an initial review by the editor, followed by reviews from two selected reviewers who provide feedback to guide the editor's decision on whether to publish the submission or request revisions from the author.
