Professor Míriam Díez taught a session on April 5th at the Doctoral Seminar of the Universidad Iberoamericana de México coordinated by Dr. Sandra Vera. The students of the seminar “Journalism and Comparative Media Systems” of the Doctoral course of this University, with whom we have an agreement for student exchange and research, had previously worked on several articles published by the group STReaM and by the Blanquerna Observatory. Students have been interested in slow journalism, the concept of post-truth and fake news and its repercussions on religion as well as on the quality in journalism.
