Low‐Carbon Energy Transition and Corporate Carbon Emissions: The Critical Role of Climate Change Mitigation Policies and Institutional Context

Business Strategy and the Environment, EarlyView.
ABSTRACT This study examines the strategic efficacy of corporate low‐carbon energy transition, such as through nuclear energy adoption, as a response to decarbonization pressures. Analyzing an international sample of energy firms, we demonstrate that the relationship between this form of transition and emission reductions is not technologically ...

Dual Relay Selection for Cooperative NOMA With Distributed Space Time Coding

IEEE Access, 2018
We consider a two-user multi-relay cooperative non-orthogonal multiple access (NOMA) network with distributed space-time coding. Two dual-relay selection strategies are proposed for cooperative NOMA, namely, two-stage dual relay selection with fixed ...
