211will be presented, in an attempt to determine how the three fields select from therhetorical sub-functions found in the analysis. Next, variation in choices of evaluativeterms within chemistry, linguistics, and economics will be further explored.6.2 Variation of rhetorical moves across disciplinesA closer examination of how each of the four rhetorical moves of the model ix isrealized in the disciplines reveals certain signs of variation. Firstly, linguistic featuressuch as text length offer consistent variation across disciplines. Secondly, although to agreat extent moves appear in a fixed order, sub-functions tend to appear in a moreflexible order. Thirdly, some sub-functions appear more frequently than others, i.e.,while in theory the moves appearing in the model include a set of sub-functions thatmostly occur together, in practice, each discipline has the possibility of varying thechoices of sub-functions appearing in each text.In this section, an attempt is made to discuss the differences which exist inexemplars of the genre across disciplines concerning three aspects:1 Differences in the length of moves.2 Differences in the order of presentation of rhetorical sub-functions withinmoves.3 Differences in the frequency of rhetorical sub-functions.6.2.1 Differences in length of movesThe most immediately noticeable variation is the differing length of BRs in thethree fields. The number of words (33,419) in the chemistry corpus was found to be
