A Diachronic Analysis of Negation In NSF Grant Proposal Abstracts (1987–2024)
Negation carries out a variety of functions in academic writing, yet the research into negation has so far mainly concentrated on the published research article and its abstract. Negation in the grant proposal abstract, a high-stakes promotional genre, has not been studied at all. Drawing on the interpersonal model of negation, this study diachronically analyzes clausal negation in a large corpus of abstracts from proposals supported by the seven directorates of the U.S. National Science Foundation (NSF). Combining quantitative trend analysis with a functional annotation of 2634 sampled concordance lines, we report three main findings. First, negation declines in NSF proposal abstracts on the whole, but this cumulative trend is driven by just two disciplinary groupings, Biological Sciences and Social, Behavioral and Economic Sciences. Second, in contrast to research article abstracts, NSF abstracts are dominated by the interactional rather than the interactive markers of negation, with affective negation, which is mostly used to outline research gaps, the most frequent function. Third, the functional profile of negation within disciplines driving the downward trend remains stable over time. We interpret these patterns in relation to the genre specificity of grant proposal abstracts and discuss implications for English for Research and Publication Purposes (ERPP).
