Attention:
As part of the submission process, we ask that each article sent to our journal generates at least two reviews by the authors. This means that, in addition to submitting their work, authors must review two articles by other researchers. Preferably, reviewers should have a doctorate. However, if this is not feasible, it is essential that the two reviews are carried out, regardless of the academic level of the reviewers.
We appreciate everyone's collaboration in guaranteeing the quality and integrity of our evaluation process.
It is strongly recommended that before submitting your article to Sigmae, you review your topic among our already published articles, because if your topic belongs to our scope, there are likely to be useful articles for your theoretical framework and discussion of the results.
Author Guidelines
Plagiarism and self-plagiarism:
Self-plagiarism occurs when an author reuses significant parts of their own previous work without proper citation. To avoid this, authors should:
- Inform the journal of any previous work that may have similarities with the submitted manuscript.
- Ensure that any previously published content is properly referenced or adapted if similar information needs to be included.
Formatting guidelines:
Note: For submissions from 01/01/2025 onwards, all articles that will be published in Sigmae must contain the Portuguese/Spanish version of the article (if the authors choose these languages) and the English version of the article.
The entire process (submission, peer review, correction and evaluation of corrections) can be done with the Portuguese or Spanish version and the authors will be responsible for sending the final version in English as well.
If the authors choose to submit the article in English, it is not necessary to have the version in another language and the entire editorial flow will continue with the English version.
Sigmae is not responsible for the translation of the article.
Note: When in tex format, make sure you send all the source files (text, images, tables) zipped up in a .zip or .rar file.
Note: Remember to link your ORCiD at submission.
The ORCiD (Open Researcher and Contributor ID) is a free, non-proprietary alphanumeric code (16 digits separated into groups of four by hyphens: 0000-0000-0000-000X) non-proprietary free of charge to identify researchers and contributors of academic research and avoid misunderstandings with people with identical or similar names, cultural inconsistencies due to spelling and inconsistencies due to changes in names (as occurs after marriage, for example), as well as allowing them to observe their academic production and follow their evolution and history as a researcher, with information that they themselves decide whether or not to share. Register for free on ORCiD.
Note: if the text is in Portuguese or Spanish, the abstract must be in the respective language, followed by the title and abstract in English. If the text is in English, the abstract must be in English only.
The titles and subtitles of the sections, subsections and sub-subsections can have any name the author(s) wishes. Section headings should be highlighted as follows:
Primary section (or section): Times New Roman font, size 14, bold, only the first letter capitalized, aligned to the left.
Secondary section (or subsection): Times New Roman font, size 12, bold, italics, first capital letter only, flush left.
Tertiary section (or sub-subsection): Times New Roman font, size 12, bold, first capital letter only, flush left.
Note:Make sure that the figures are inserted in the text, not at the end of the document as annexes.
Note: Make sure that all figures are cited in the text. If it is not cited in the text, it will be placed as an appendix.
Example:
Figure 1: Title of figure 1. (in the same language as the whole text)
<Image here>
Source: Google images (20xx). OR from the authors (20xx). (in the same language as the whole text)
Legend: xxxx (if any) (in the same language as the whole)
Note: Remember to send a graphical abstract of your article (see how to make a graphic summary here), to be the cover when it is published OR to indicate in the “Comments to the Editor” which picture you would like to be your cover. The graphical abstract or cover image must be in .png or .jpeg format.
Note:Make sure that the tables are inserted in the text, not at the end of the document as annexes.
Note: Make sure that all tables are cited in the text. If it is not cited in the text, it will be placed as an appendix.

Graphical abstract:
This is a figure that will present the main conclusions of your article, presenting the content of the article to readers in a visual way, so that they grasp the essence of the work and understand it, quickly, clearly and objectively.
See guidelines for preparation here.
The visual summary is recommended, but we will also accept the indication of a figure from the article itself to make up the space next to the article (article cover) in the published edition.
The graphical abstract should be inserted in a separate file from the manuscript, in .png ou .jpeg or the figure should be indicated in the “comment to the editor” field.
