My special thanks to Carol Steig for her earlier work with me on this project. David Rosik contributed significantly to the general MR survey; Steve Bruun produced the cross-tabulated statistical analysis for the design/coding survey and contributed, along with Carolyn Larson, Julie Federico, H. C. Wei, and Tony Lenard, to the analysis of the design/coding survey; and Clive Loader increased our understanding of the Chi-Square analysis. We especially thank Marjory P. Yuhas and Lew G. Anderson for their unflagging support of this work. And finally, we thank all those who participated in the survey.
