This week’s CAIRNS Etanhan Wotanin column is another in a series celebrating our 20th year as a nonprofit organization. The series is called “Twenty for Twenty” and this one describes the Four Rs of Rigor, Reliability, Respect, and Relevance, which are grounded in both academic scholarship and cultural competency, that guide our work. The column, “Twenty for Twenty: The Four Rs,” can be read now by clicking here, or later this week in the Lakota Times newspaper.
