Thinking about the nature of narrative

What is a narrative? Does it require "a central character who encounters a problem, and the problem is somehow resolved?" Or is it, more broadly, "an account of connected events?" DeLene Beeland discusses that question — and how writing is like deconstructing a Jenga tower ("what we take out of our writing is just as important to the integrity and strength of a piece as what we keep in") — in a recap of a session at the just-concluded ScienceOnline2013 conference.
