CONSIDER Table 1. It represents in its formal characteristics a situation which arises in the clinical-social-personality areas of psychology, where it frequently occurs that the only useful level of measurement obtainable is nominal scaling (Stevens, 1951, pp. 2526), i.e. placement in a set of k unordered categories. Because the categorizing of the units is a consequence of some complex judgme...

In a previous article (Hakuta, Bialystok, & Wiley, 2003), we tested the critical-period hypothesis for second-language learning using 1990 U.S. census data. Our findings failed to support a critical period for second-language acquisition, demonstrating greater evidence for a steady decline throughout the life span. Stevens (2004) questioned these findings, suggesting they might have resulted in...

Two-Stage Problems with Stochastic Order Constraints. Darinka Dentcheva, Department of Mathematical Science, Stevens Institute of Technology. Abstract: We consider two-stage risk-averse stochastic optimization problems with a stochastic-order constraint on the second stage decisions. The usual stochastic order, the increasing convex order and a multivariate stochastic order will be discussed. W...

Turner [9] showed how a pure functional programming language could be implemented using combinatory logic in a practicable way. This method is currently out of fashion, but for some time I have believed that its full potential is still to be realized. This belief was partially vindicated by Stevens [7] who developed a family of interesting algorithms which use a novel notation for combinators. ...
