A contrastive analysis of epistemic modality in scientific English

[ES] This paper investigates the use of epistemic expressions in scientific English. The main aim of this research is to analyse if native speakers of English use epistemic modality in the same way than non-native speakers of English and to detect the most outstanding cognitive implications of this fact. The corpus used in this research contains 50 research papers written by native English speakers and 50 scientific papers written by Spanish researchers who use English to communicate internationally. As epistemic modals are used to indicate the possibility of some piece of knowledge, this paper focuses on epistemic modal verbs in order to detect if native speakers of English and non-native speakers of English communicate modality in the same way, or if there are differences in frequency and use. The results obtained in this analysis indicated that there are differences in the frequency of use of epistemic expressions, even if the intention of the writers is the same.

How scientific is the science in ethnopharmacology? Historical perspectives and epistemological problems

This commentary is based on a general concern regarding the low level of self-criticism (-evaluation) in the interpretation of molecular pharmacological data published in ethnopharmacology-related journals. Reports on potentially new lead structures or pharmacological effects of medicinal plant extracts are mushrooming. At the same time, nonsense in bioassays is an increasing phenomenon in herbal medicine research. Only because a dataset is reproducible does not imply that it is meaningful. Currently, there are thousands of claims of pharmacological effects of medicinal plants and natural products. It is argued that claims to knowledge in ethnopharmacology, as in the exact sciences, should be rationally criticized if they have empirical content as it is the case with biochemical and pharmacological analyses. Here the major problem is the misemployment of the concentration-effect paradigm and the overinterpretation of data obtained in vitro. Given the almost exponential increase of scientific papers published it may be the moment to adapt to a falsificationist methodology.
