We compared single-sample methods, proposed by Russell et al. and Bubeck et al., and camera-based methods in calculating 99mTc-MAG3 clearance, and determined camera-based methods that provide estimates comparable to those measured by the Russell method. Twenty-one patients underwent 99mTc-MAG3 renal scintigraphy, and clearance was measured by the Russell method and Bubeck method. Various renogr...

Recently, Chambers et al. (Journal of Economic Theory 70 (1996) 407}419; Working Paper, Southern Illinois University, Carbondale, 1996) have developed the concept of directional distance to measure technical e$ciency. However, there is no guarantee that such a measure must intersect the e$cient subset (also called strong e$cient subset) de"ned by Koopmans (Activity Analysis of Production and Al...

1 Introduction ✤ Just as there is the Russell paradox about sets, so there is the Russell-Myhill paradox of propositions. ✤ While predicativity has been well-explored as a response to the Russell paradox of sets, there seems to have been no previous attempt to set out a predicative solution to the Russell-Myhill paradox of propositions. ✤ The aim of this talk is to do that, within the framework...
