:::They are in the Discussion section, a common feature of many journals.  I do not know IJHE's specific standards on how much peer review is done of those statements.  However, I don't see any fair justification in us trying to make some judgment about that, unless you have clear, documented evidence in a reliable source that says that those publications (or that Discussion articles in IJHE in general) were not peer-reviewed. In any event, they certainly aren't "self-published".
