Correction

In the course of type-setting the article [1], the first two sentences of the background section were inadvertently printed without quotation marks. These two sentences are a direct quote from the paper referenced, and as such, require quotation marks. In addition, the formatting for this reference was printed with the number [1] as well as the author names. Correct formatting includes only the [1]. The referencing for these sentences is now correct. The authors regret this error.

The erroneous text was:

In many respects, the most troublesome problems of any science centre around its most basic terms and fundamental concepts, and not around its more sophisticated concerns. Indeed to the extent that everything either follows from or is based on a discipline’s most basic terms and fundamental concepts, problems at a higher level can always be traced back to problems at a more fundamental level. (Mitroff & Sagasti, 1973) [1].

This text should have read:
