The series on child care really is excellent and long overdue. However, in the first article I quoted some statistics on child-care quality. I would like to point out that the actual research for these statistics was conducted by Michael Olenick, who studied child-care quality for his doctoral research at UCLA. I worked closely with Olenick as his faculty supervisor and employer. However, the research is his and the exact findings are in his dissertation. Proper attribution is important to both him and me. Thank you.
