I thought Wikipedia wanted secondary sources (i.e. newspapers, journals, textbooks, biographies) that have reported on primary sources (individual papers, original research).
I also thought it was frowned upon to cite your own research.
You are correct. WP still does want secondary sources, exactly as you state: http://enwp.org/WP:V and WP:IRS Independent reliable sources, and does not want WP:OR. IMHO it's ok to discuss one's own work on an article Talk page, in the light of a future improvement to the article, as in, "I've just finished this, it's in peer review now, it's slated for publication on (future date), and it's relevant to update/correct (section). I'll come back and notify y'all if it receives commentary by others elsewhere."

Have these positions changed?
