This paper applies the co-integration technique and causality test to examine the dynamic relationships between pollutant emissions, energy use, and real output during the period between 1990 and 2007 for Russia. The empirical results show that in the long-run equilibrium, emissions appear to be energy use elastic and output inelastic. This elasticity suggests high energy use responsiveness to changes in emissions. The output exhibits a negative significant impact on emissions and does not support EKC hypothesis. These indicate that both economic growth and energy conservation policies can reduce emissions and no negative impact on economic development The causality results indicate that there is a bidirectional strong Granger-causality running between output, energy use and emissions, and whenever a shock occurs in the system, each variable makes a short-run adjustment to restore the long-run equilibrium. The average speed of adjustment is as low as just over 0.26 years. Hence, in order to reduce emissions, the best environmental policy is to increase infrastructure investment to improve energy efficiency, and to step up energy conservation policies to reduce any unnecessary waste of energy. That is, energy conservation is expected to improve energy efficiency, thereby promoting economic growth. (C) 2011 Elsevier Ltd. All rights reserved.

The booming of Integrated Circuit (IC) design service has become a critical sub-industry to the evolution of semiconductor industry. In this paper, we took the case of a tier one IC design service company to explore the core competences of this emerging industry. Seven core competences are defined throughout the research. More specifically, this paper analyzes the in-depth of the interrelation among the core competences by utilizing the DEMATEL method. They are divided into causal and effect groups, enabling readers to gain a better understanding of the interactive relationship between them, as well as making suggestions for improvement to enhance their overall performance. The result has shown that the Intellectual Property (IP) design capability is the most important core competence. Enhancing five of the core competences in the causal group will improve the overall performance. Further, DEMATEL method is demonstrated as a useful approach in exploring the interrelationship.
