“…Focusing on research articles, PhD dissertations and Master's theses in four disciplines of electrical engineering, biology, business studies, and applied linguistics, Hyland (2008: 13-14) classified a bundle as research-oriented when it "helps writers to structure their activities and experiences of the real world" (e.g., the use of the, the structure of the), as text-oriented when it is "concerned with the organisation of the text and its meaning as a message or argument" (e.g., in the next section, in the case of), and as participant-oriented when it "conveys the writer's attitudes and evaluations" or "addresses readers directly" (e.g., are likely to be, it should be noted). These two functional frameworks proposed by Biber et al (2004) and Hyland (2008) have been widely applied to investigate bundle functions in research writing, such as exploring variation across registers (e.g., Biber and Barbieri 2007), L1 and L2 speakers of English (e.g., Ädel andErman 2012), anddisciplines (e.g., Durrant 2017;Hiltunen 2018;Borucinsky and Pritchard 2022).…”
