The teaching-research nexus has been studied by many researchers, mainly looking at pedagogic links and direct benefits arising from the interaction of both activities. The paper takes a comparative approach, looking at the relationship between teaching and research in four universities from two different countries. This paper argues that contextual factors are vital in shaping the nature of the relationship and also identifies differences between disciplines in how these contextual factors may be understood. In particular, the contrasting structural and political contexts provided by two different national settings are seen to have a crucial role in shaping institutional activity. (Contains 2 tables.)
