The roles of multinational enterprises in governing the sustainability of global supply chains
International Journal of Management Reviews, EarlyView.Abstract An extensive but fragmented body of research shows that multinational enterprises (MNEs) engage with multiple sustainability rules in global supply chains (GSCs) spanning the private, social and public governance sectors. MNEs perform diverse roles by either shaping or complying with these rules.

Fish welfare in a changing world: New developments and current challenges
Journal of Fish Biology, EarlyView.Abstract The welfare of non‐human animals is central to ethical discussions on animal use, with increasing attention to fish welfare across research, aquaria, aquaculture, and fisheries. This paper reviews current theoretical approaches to animal welfare and recent advances in defining and assessing fish welfare since the seminal paper by Huntingford ...
