This paper rounds out their discussion by highlighting some limitations of their research agenda, providing a critical review of the contributions of accounti...

When carrying out a research project, some materials may not be available in-house. Thus, investigators resort to external providers for conducting their research. To that end, the exchange may be formalised through material transfer agreements. In this context, industry, government and academia have their own specific expectations regarding compensation for the help they provide when transferr...
