A Cross-Disciplinary and Linguistic Study of Context Frames in Research Article Abstracts

This study intends to scrutinize the realizations and discourse functions of context frames in research article abstracts written by native and non-native writers of English from four disciplines namely: Applied Linguistics, Economics, Biology, and Mechanical Engineering. To this end, 200 research article abstracts (50 from each discipline) were selected for analysis. From the 50 research article abstracts of each discipline, 25 were written by native writers of English and 25 written by Iranian non-native writers of English. The corpora, then, were analyzed based on the analytical framework proposed by Ebrahimi (2014). Based on the findings obtained, it can be concluded that the context frame’s selection, frequency and discourse functions are affected and imposed by the nature of discipline and genre of RA abstracts. The result also indicated that there is a difference between native and Iranian non-native writers of English in dealing with these elements. In addition, the findings stress the fact that writing is restricted by the disciplinary conventions and writers’ background knowledge of English language.
