This presentation applies 'critical dialectics' (ie., "logic focusing on contradictions in social context") to analyze the phenomenon where "the word open is used as if the concept were essentially good." It is not hard to think of instances of 'open' which are bad - an 'open wound', for example, or leaving your front door open while you're on a business trip. Heather Morrison focuses on one of those contradictions, where 'open' is reified to the point where it means 'open for business' (ie., open for commercial exploitation). I think that while the presentation may rely too much on the ambiguity of the word 'open' the points raised are nonetheless good ones. Abstract and slides only; no audio or video, unfortunately.
