ACKNOWLEDGMENTS
First,I thank Joanne Lobato who organized the National Science Foundation “International Working Conference:Addressing the Transfer Dilemma” (REC-0450208) in San Diego,January 13-16,2005 from which this article originates.We were actually six people determined to challenge “the doctrine of sameness”:King Beach,Yrj? Engestr?m,John Mason,Ricardo Nemirovsky,Nephi Thompson,and myself.The joint article still remains to be written.When writing this version of mine,I immensely profited from our initial discussions and from the comments I had received.John Mason,Yrj? Engestr?m,and Thabit Al-Murani have read an earlier version of this article,and they contributed to its betterment with comments,suggestions,and support.After submitting the article,I received constructive critique and highly helpful suggestions from James G.Greeno,two anonymous referees,and the editors (Janet Kolodner ＆ Joanne Lobato).John Mason read and commented on this latest version of the article,too.Lisbetth S?derberg helped to bring the whole thing to-gether.I am deeply moved by the generosity of all involved.
