IMPORTANT ALERT: ONLINE FRAUD ATTEMPT

Sigmae warns its authors, readers and contributors about online fraud attempts. We emphasize that our publication and communication guidelines are clear and transparent:

  • Sigmae  does not issue invitations to associations or societies.
  • We do not charge any fees for submitting, evaluating or publishing articles.
  • Sigmae has only 2 official means of communication: the journal's website (via the OJS platform) and the official e-mail (sigmae@unifal-mg.edu.br).

 

Any approach on behalf of Sigmae requesting payments or invitations outside of this context or contacts by other unofficial means of communication is an attempt.
In case of doubt, please contact us directly at sigmae@unifal-mg.edu.br.
Protect yourself!
