We present evidence on productivity improvement experienced by the research institutes of the Chinese Academy of Sciences (CAS) after its implementation of the Knowledge Innovation Program (KIP). Using a balanced panel of data on R&D inputs and outputs of 59 research institutes in CAS, we analyze the productivity, technological and efficiency changes from 1997 to 2005. We document that the CAS...
It is well known that the discrimination power of data envelopment analysis (DEA) models will be much weakened if too many input or output indicators are used. It is a dilemma if decision makers wish to select comprehensive indicators, which often have some hierarchical structures, to present a relatively holistic evaluation using DEA. In this paper we show that it is possible to develop DEA models...
The polarity of residues at certain positions in the transmembrane domains of G-protein coupled receptors (GPCR) is found to be conserved, and to indicate the pattern of specific helix-helix packing of the helices. A concept of polarity conserved positions (PCP) is proposed to describe this conserved property, and is applied to obtain insight into the structural features of the transmembrane proteins...
