patterns and variations in native and non-native interlanguage pragmatic rating: effects of rater training, intercultural proficiency, and self-assessment
although there are studies on pragmatic assessment, to date, literature has been almost silent about native and non-native english raters’ criteria for the assessment of efl learners’ pragmatic performance. focusing on this topic, this study pursued four purposes. the first one was to find criteria for rating the speech acts of apology and refusal in l2 by native and non-native english teachers...
15 صفحه اولGlacial-driven vicariance in the amphipod Gammarus duebeni.
We have examined the genetic diversity using mitochondrial COI and ND2 sequence data from 306 specimens of the amphi-Atlantic-distributed amphipod Gammarus duebeni. Marine populations from the Atlantic Ocean, the Baltic and North Sea, as well as freshwater populations from Ireland, Cornwall and Brittany were analysed. G. duebeni is a complex of five allopatric lineages. Freshwater populations r...
متن کاملTranscript analysis of some defense genes of tomato in response to host and non-host bacterial pathogens
The transcript levels of six defense genes including pathogenesis-related gene 1 (PR-1), pathogenesis-related gene 2 (PR-2), pathogenesis-related gene 5 (PR-5), lipoxygenase (LOX), phenylalanine ammonia-lyase (PAL) and catalase (CAT) were investigated in tomato plants inoculated with Xanthomonas axonopodis pv. phaseoli as a non-host pathogen and X. euvesicatoria as a host pathogen. Activation o...
متن کاملGammarids in Lake Constance: habitat segregation between the invasive Dikerogammarus villosus and the indigenous Gammarus roeselii
Over the past decades the invasive Ponto-Caspian gammarid Dikerogammarus villosus spread throughout large rivers of central Europe, thereby rapidly displacing most of the native gammarid species. In 2003, D. villosus was fi rst observed in Lake Constance and was predicted to out-compete the native Gammarus roeselii. However, today the two species coexist at several sites. We hypothesized that a...
متن کاملTranscriptome of the freshwater amphipod Gammarus pulex hepatopancreas
So far, ecotoxicological studies used biomarkers of exposure or of effects in order to investigate the impacts of contaminated areas on biota (Peakall, 1994 [6]). However, although these results are important in the ecotoxicological risk assessment, biomarkers are very specific and only provide information on the biological processes or physiological pathways targeted by the biomarkers experime...
