All appeals and complaints should be sent to the editorial office by email, zssyqkzx@126.com, and will be considered by the Editor-in-Chief (EIC) unless the EIC has a conflict of interest, in which case an Associate Editor (AE) will handle the issue. The Editor-in-Chief has the final say when considering all complaints and appeals of decisions. Many manuscripts are rejected by the EIC, in consultation with an AE, without external peer-review based on a judgment that they do not fit the scope or quality standards of the journal. These assessments are unlikely to change on appeal. Similarly, a decision obtained after a well conducted peer-review process is not often overturned by the EIC. A well-founded appeal should clearly describe why specific grounds for a decision are demonstrably wrong. All appeal decisions are made by the EIC and are final.
