Disciplinary variations in academic promotional writing: the case of statements of purpose
Bibliographic record
Abstract
Abstract This paper explores disciplinary variations in academic promotional writing via a comparative analysis of statements of purpose (SoPs) written for different disciplines. A total of 100 SoPs written by English as an additional language (EAL) applicants from mainland China were collected, which were drawn from five academic disciplines: business, engineering, humanities, science and social science. Following a corpus-driven research design, these SoP samples were analyzed in terms of their lexico-grammatical and rhetorical features. The data analysis suggests that although on the surface these SoP samples share similarities in lexico-grammatical and rhetorical features, they are quite different in terms of their preferred persuasion strategies. While SoPs written for engineering and science primarily base their self-promotional arguments upon the applicants’ previous research experiences and future research prospects, those written for business, humanities and social science tend to focus on how the applicants’ unique Chinese socio-cultural backgrounds would contribute to their desired programs. The above finding sheds light upon how academic genres are invariably embedded in disciplinary practices, with each discipline having its own communicative purposes, discourse community members, academic expectations and disciplinary constraints.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
