Correction to: Palgrave Communications 3:24 10.1057/s41599-017-0012-5; Published 14 Nov 2017

In the section “Heteroglossia as authoritative discourse and internally persuasive discourse” the sentence “All of the excerpts and images taken from IDEC 2016 excerpts 1, 3, 4, 5 are accessible in the public domain as all of the content used is from online videos” has been corrected to “All of the excerpts and images taken from IDEC 2016 excerpts 1, 3, 4, 5 are accessible in the public domain as all of the content used is from online videos”.

This has now been corrected in the HTML and PDF versions of this article.
