52Dudley-Evans acknowledges the presence of key move cycles, a combination of atleast two moves in a predictable order that commonly appears in Evaluation, usuallyinvolving Statement of Results, Finding, Reference to Previous Research, and Claim.Evaluation can encompass either a two-move cycle of Statement of Results (or Finding)and Reference to Previous Research, or it can have a three-move cycle of Statement ofResults or Finding, Claim, and Reference to Previous ResearchTo stress the importance of linguistic features in textual staging, i.e., thedetermination of moves in the rhetorical structure of the genre, Dudley-Evans states that‘it is possible to classify the moves on the basis of linguistic evidence’ (1994:226) suchas citations (Reference to Previous Research) and hedging (Claim). A main point inDudley-Evans’ work is that it calls attention to the importance of defining rhetoricalmoves of other genres besides the research article, and of understanding the expectationsthat members of particular disciplines have in relation to exemplars of a given genre.2.4 Using Swales’ genre-analytical approach to study book reviewsAs seen in this chapter, there is no unified view on how to capture genreboundaries, and in trying to do so, authors (e.g., Swales, Hasan) have produced anumber of differing frameworks of analysis, with different conceptualizations of thevery term genre. In the present study, I have opted for Swales’ genre-analytical approachwhich is believed to best capture the purpose of the study, namely to investigaterhetorical structure of a genre contextualized in different discourse communities. Genreswill be considered here as abstractions of systems of texts that recur in comparablerhetorical situations (Swales, 1993a; Devitt, 1993; Miller, 1984).
