This study compares the relative role of impression management tactics and the other form of supervisor–subordinate guanxi (s–s g) in predicting supervisor-rated employee performance. Empirical data were collected from 175 supervisor-subordinate dyads working full-time in Taiwanese organisations. Specifically, this study uses the Dominance-based Rough Set Approach (DRSA) to formulate employee s...

During an investigation of the cultural requirements of certain bacteria, the writer isolated from the hydrolytic products of casein, a fraction of material which was apparently required by hemolytic streptococci for satisfactory growth, and which was found on examination to contain a considerable amount of sulfur (1). The sulfur was apparently not in the form of cystine since it did not give t...

Our aim in this project is to develop a Mach-uniform method for nearly compressible two-phase flow problems where the flow speed is much less than the speed of sound of the underlying fluid components. The accuracy and efficiency of the method under development should depend weakly on the Mach number in the full range from zero to supersonic values. Representative applications of this kind are ...
