Rejoinder.

The article authors comment on the views of sociologist Christen T. Jonassen on a paper on problem children by the authors. The real difficulty which the authors have encountered in responding to this criticism has been their inability to determine what Jonassen assumed the basic issues to be. His objection to the authors' explanation of the behavior of immigrant groups in terms of adjustive and distributive processes suggests that to him this is the real issue. The alternatives, however, are not clear unless one accepts the notion of the innate superiority of some people over others. It would appear, as suggested both here and in other works, that Jonassen would explain the movement and delinquency of ethnic groups in terms of their Old World culture plus some "personal" or "volitional" elements which he seems to designate as "non-cultural." Jonassen's interest in the effect of Old World culture on rates of delinquents is shared by the authors, but their data are not centered on this problem. The first reason is that most of the boys used in the calculation of rates in this study were born and reared in the U.S., and can be identified with foreign cultures only through their parents.
