Dialogic Evidence: Documentation of Ephemeral Events is the title of a presentation delivered by Paul Stapleton at the AHDS Performing Arts Summer School: Digital Representations of Performing Arts.
The abstract is available here.
A different presentation under the same title will be delivered at DRHA 2007.
Both presentations aim to contextualize and reflect on the recently finished research project Dialogic Evidence: Documentation of Ephemeral Events.
This is the link for the Sonic Arts Research Archive.
Its really very in need of some work, though.
