This paper aims to explore the notion of power relations and interactional dominance among scientists from different cultural backgrounds in department meetings. The concept of dominance is of a particular interest in this paper since this study seeks to explain how interactional dominance manifests itself linguistically in the meetings. According to Itakura, “spoken interaction is seen as being inherently asymmetrical since interlocutors are bound to differ in their control of the content, quality and quantity of their dialogical contributions” (2001, p.42). Similar to Itakura’s discussion, the results of the analysis reported in this study revealed that interactional dominance was actually manifested among communicators from different backgrounds through spoken interactions in the meetings.
