Hi Stephen,

Presentation at a conference prior to full publication in the literature isn't unusual. I'm not sure if the proceedings of this meeting are peer reviewed or not - I've certainly has stuff published in conference proceedings that were as heavily peer-reviewed as a journal.

God is our guide! from field, from wave, From plough, from anvil, and from loom; We come, our country's rights to save, And speak a tyrant faction's doom: We raise the watch-word liberty; We will, we will,we will be free!
