Comparative judgment is a method that allows measurement of competence by comparison items with other items. In educational measurement, where comparative becoming an increasingly popular assessment method, are mostly students’ responses to assignment or examination. For assessments using judgment, the Scale Separation Reliability (SSR) used estimate reliability measurement. Previous research h...

We have developed a compiler for Standard ML which allows instantiation of a xed set of higher order functions with equivalent parallel algorithmic skeletons written in C and MPI. The compiler is intended to be both portable and semi-automatic. Here we discuss the performance of the code generated by the compiler, for ve exemplar programs on six MIMD parallel machines. Results suggest acceptabl...

(Received for publication, August 31, 1959) It goes without saying that x-ray examination is of highest value in the diagnosis of gastric cancer in general. There are a number of com plementary diagnostic methods next in importance to it and particularly, cytological diagnosis of gastric cancer has recently come to be evaluated very highly.1-26) The present authors have already published severa...

555 Adaptive speckle reduction, which is designed to improve image contrast, dramatically alters the familiar appearance of the ultrasonographic B-mode scan. The acceptability to radiologists of this alternative method of display was assessed. Four experienced radiologists selected B-mode scans from 83 liver and 71 breast examinations and graded the change in diagnostically important features a...

Given a social network, which of its nodes have a stronger impact in determining its structure? More formally: which node-removal order has the greatest impact on the network structure? We approach this well-known problem for the first time in a setting that combines both web graphs and social networks, using datasets that are orders of magnitude larger than those appearing in the previous lite...
