The journal adheres to the Committee of Publication Ethics (COPE) principles and good practices for transparency in academic publications.

Policy on falsification, data manipulation and plagiarism

The editorial team, including the editor, authors and reviewers must follow the international ethical standards defined by the Committee on Publication Ethics (COPE), especially those related to:
1. Fabrication, falsification or omission of data.
2. Plagiarism
3. Redundant, duplicate or fragmented publication
4. Omission of citations and references to sources consulted
5. Use of content without permission or without justification
6. Individual appropriation of collective authorship
7. Changes in authorship
8. Undisclosed Conflicts of interest (CDI)
9. Any and other ethical breach that may arise in the research and publication process.

The fabrication of results occurs when the author makes up ideas and data. Falsification results from data manipulation by the authors. Omission originates when the authors deliberately conceal a fact or information in order to change their research results. Plagiarism occurs when an author presents data created by others as their own ideas. The following are types of plagiarism: direct copying of a text without quotation marks or citing the source, modification of some words in the text, paraphrasing and lack of acknowledgments; self-plagiarism occurs when the same author reuses his own material that has already been published, but without indicating the reference to the previous work. Redundant or duplicate publication refers to the total, partial or altered copy of a work already published by the same author.

In case of suspicion of any misconduct, we will follow the flow charts prepared by COPE in order to determine the corresponding actions

Crossmark Policy

The University of Medellin recognizes the importance of maintaining the integrity of academic and research data for researchers, libraries, and professionals. For this reason, it uses the CrossMark tool to ensure reliable content and inform readers of changes and updates that occur in articles published in scientific journals.

By clicking on the CrossMark logo included in each article, the system will display information about the modification history after publication and its current status. Changes will be made in circumstances that merit it. This includes errata, changes of importance such as incorrect data or information that generate understanding problems. The corrected version will replace the original and the corrections made will be indicated.

Following the recommendations of the COPE (Committee on Publication Ethics) for good practices in scientific and bibliographic publication, the change policy will be adjusted to the following circumstances:

• Corrections to an article: Changes or corrections will be adjusted to significant errata discovered after publication that may mislead readers. This may be the result of an error by the authors or an error introduced during the editorial process of the journal.
• Retraction: This action will be implemented in articles that are found to have serious deficiencies that may affect the data and results. These may include unintentional errors reported by the authors (e.g., in data, instruments, or analyses), as well as issues of non-compliance with good practices (data fabrication, plagiarism, unethical research, publication duplication or overlap, image falsification or manipulation, among others). For any retracted article, the reason that prompted the retraction will be clearly indicated in the retraction note that will be published alongside the retracted article. This note will appear with a watermark and will clearly indicate that it has been retracted.
• Article removal: The removal of an article will be carried out when legal limitations are imposed, it is defamatory, or infringes the legal rights of third parties.
