True Superconductivity in a 2D "Superconducting-Insulating" System

We present results on disordered amorphous films which are expected to undergo a field-tuned Superconductor-Insulator Transition. Based on low-field data and I-V characteristics, we find evidence of a low temperature Metal-to-Superconductor transition. This transition is characterized by hysteretic magnetoresistance and discontinuities in the I-V curves. The metallic phase just above the transition is different from the "Fermi Metal" before superconductivity sets in.Comment: 3 pages, 4 figure

Managing project success using project risk and green supply chain management

Purpose: The implementation of the risk management in the development of new car models can contribute to the improvement of the project management performance and project success. The purpose of this paper is to provide evidence about whether project risk management (PRM) and green supply chain management (GSCM) are positively related to project management performance and the project success. Design/methodology/approach: Data were collected from 145 project managers in the Malaysian automobile manufacturing industry and analyzed using structural equation modeling. Findings: The results found that PRM and the GSCM had a positive association with project management performance and the project success
