Medicine for the Material World
Archaeometry, EarlyView.ABSTRACT It is clear that many of the inorganic materials of antiquity have been used both as medicines for human ills and also as agents in technological processes. This paper speculates that there might have been a stronger link between these two functions in the past, based on the concept of “active agents”—materials that are efficacious at curing ...

ESG, Bank Debt and Firm Value: A Signaling Perspective
Journal of International Financial Management &Accounting, EarlyView.ABSTRACT This paper delves into the influence of bank debt in shaping the relationship between environmental, social, and governance (ESG) performance and a firm's value. As a result of the superior informational and monitoring functions of bank borrowers in their lending relationships, we argue that a firm's degree of bank debt might signal the ...
