Issues concerning the pre-fixed generic structure analytical models for academic writing have emerged through the development of the three so-called traditions of genre analysis: English for Specific Purposes (ESP) and English for Academic Purposes (EAP), Systemic Functional Linguistics (SFL), and New Rhetoric. Political issues, such as imposing a monolithic writing structure, that impose ethnocentric-dominant writing that maintains power relations are highlighted. This chapter introduces the main purpose of this book, which is to present a genre analysis conducted under the understanding that genre is an open system (Croce, Aesthetic as science of expression and general linguistic. (D. Ainslie, Trans.) (2nd Edition). London: Macmillan, 1929; Derrida, The law of genre. In D. Duff (Ed.), Modern genre theory (pp. 219–31) (A. Ronell, Trans.). London/New York: Routledge, 2014; Frow, Genre. London: Routledge, 2006). More specifically, the integration of the prototype theory and structuralism is proposed as a new approach to generic structure analysis in academic writing studies.
