I would have liked to see a direct link to the research paper, and told more about it: name, release date, length, sponsor; especially since the whole article is based on it.

This might be it:

Judge, T. A. (2009). Core self-evaluations and work success.

Current Directions in Psychological Science, 18, 58-62.

- but there are lots of similar papers linked from Judge's site. http://www.ufstudies.net/tim/VITA/
