Margaret Zulick and I are putting together a panel for NCA in Chicago on the critical re-examination of Walter Fisher's Narrative Paradigm after thirty years. There is space for additional papers - if you are interested in submitting an abstract for this panel please contact me and I will send you the panel description. This is rather a last minute addition after it occured to me that Professor Fisher first published his concept of the narrative paradigm thirty years ago. Examinations of the influence of this concept, case studies, critical reconceptualizations, etc., will be welcomed.
No doubt this is the kind of question one could answer by going out and becoming learned. But instead I will ask you, who have already done so: What is an appropriately technical way to talk about usage of "or" in a redundant or synonymic dyad, vs. "or" in an actual logical divergence?
