"Sports Mascots and the Media" with co-authors (i.e., C. Richard King, L. R. Davis-Delano, E. J. Staurowsky,& L. Baca), in Handbook of Sports and Media, A. A. Raney & J. Bryant, editors, 2006, Lawrence Erlbaum Associates.I haven't looked at these references or at the specific evidence regarding the harm of Native American nicknames on Native Americans. Regardless, I hasten to point out again that I personally think Native American sports nicknames and mascots are objectionable--especially the Washington Redskins (which just now felt wrong even to type out loud) and Chief Illiniwek--even if they do not cause specifiable and demonstrable harm to particular Native Americans. The issue arises more from my experience doing quantitative social research with it being much easier to assert that something is harmful than to demonstrate persuasively that it is so, as well as my belief that professional resolutions that make claims about empirical matters should have some explicit connection to empirical evidence. I recognize how quaint and protocurmudgeonly such sentiments might seem.
"Of Polls and Race Prejudice: Sports Illustrated's Errant 'Indian Wars,'" with co-authors (i.e., C. Richard King, E. J. Staurowsky, L. Baca, L. R. Davis, & C. Pewewardy), in Journal of Sport and Social Issues, 2002, 26(4): 381-402.
With acknowledgment that it was dated, I was also referred to the bibliography for the resolution by the American Psychological Association. Even if one is not interested in the bibliography per se, the previous link is worth clicking on by academics just for the apparent contrast between an APA resolution and an ASA resolution, especially in terms of how the former make concrete points and tie them to specific citations of evidence.
