Production and falsification of data:
Data falsification means that the researcher did not actually conduct research, but falsified the data. Falsifying data means that the researcher performed an experiment, but then changed some of the data.
Plagiarism:
All articles sent to the editorial office of the journal HEAD AND NECK are subject to anti-plagiarism checks. Copying even one sentence from someone else’s manuscript or even one of the previously published sentences without proper citation is considered plagiarism.
Duplicating your own publications:
Dear Authors, It is unethical to post the same manuscript in several journals at the same time. This wastes the time of editors and reviewers and can damage your reputation and that of the journals if they are published in more than one journal. In case of submission of the same article to two or more peer-reviewed journals, later applications must be withdrawn.
Redundant publications:
This means the publication of many very similar manuscripts based on the same experiment. Combining your results into one very reliable article is likely to interest our journal. The editorial staff of HEAD AND NECK will reject your article if it is weak.
Incorrect author contribution or source citation:
All the listed authors had to make significant scientific contributions to the study of the manuscript and approve all of its statements. Be sure to list everyone who has made significant scientific contributions, including students and laboratory assistants. Do not «gift» authorship to those who did not contribute to the writing of the article. The International Committee of Medical Journal Editors has detailed guidelines on authorship that are useful to scientists in all fields: http://www.icmje.org/recommendations/browse/roles-and-responsibilities/defining-the-role-of-authors-and-contributors.html
