The review process for LUMEN Publishing journals is strictly anonymous; therefore, neither the reviewers nor the editor-in-chief can be engaged in correspondence with the author or authors at any point during the review, or after the review process. If there are any complaints, these can be addressed to LUMEN Publishing House at the e-mail address,

For any other complaints, (ethical complaints – possible misconduct, plagiarism, copyright, authorship, etc.), please address an official letter to the LUMEN Publishing House team which will redirect your complaint to the Editorial Team of the journal.
