although studies on pragmatics in general and politeness in particular abound in the literature, impoliteness has been largely ignored. in the present study, participants filled out either the persian or english version of a discourse completion test (dct). the researchers analyzed collected answers to discover the relationship between impoliteness and power. furthermore, the researchers compar...

This study investigated the relationship between Iranian high school students’ Universal Grammar knowledge and their performance on such standardized general English proficiency tests as PET and FCE internationally administered by Cambridge University. To this end, 108 students were randomly chosen from some high schools located in Malayer from Hamedan. Since this study was correlational in nat...

OBJECTIVE To determine whether doctor-patient encounters in general practice with patients from a non-English-speaking background (NESB) differ from encounters with patients of English-speaking background (ESB) in terms of the type of practice where the encounters occur and the type of problems managed. DESIGN AND SETTING A national cross-sectional survey of GP-patient encounters from a sampl...

There is a growing interest among the higher education principals and policy makers to improve teacher evaluation methods and more important than that to use the evaluation data. A number of research studies implied the ineffective instruction of ESP courses in Iran (Atai, 2002; Eslami, 2005; Hayati, 2008; Ahmadi, 2008; Sherkatolabbasi & Mahdavi, 2012; Boniadi, Ghojazadeh & Rahmatvand, 2013). T...

NGC 1275 in the centre of the Perseus cluster of galaxies, Abell 426, is surrounded by a spectacular filamentary Hα nebula. Deep Chandra X-ray imaging has revealed that the brighter outer filaments are also detected in soft X-rays. This can be due to conduction and mixing of the cold gas in the filaments with the hot, dense intracluster medium. We show the correspondence of the filaments in bot...

Globular cluster populations of supergiant elliptical galaxies are known to vary widely, from extremely populous systems like that of UGC 9799, the centrally dominant galaxy in Abell 2052, to globular-cluster-poor galaxies such as NGC 5629 in Abell 2666. Here we propose that these variations point strongly to the existence of a population of globular clusters that are not bound to individual ga...

With a high spatial resolution imaging instrument such as the Chandra/ACIS, one can confidently identify an X-ray source with only a few detected counts. The detection threshold of such sources, however, varies strongly across the field-of-view of the instrument. Furthermore, the low detection counting statistics, together with a typical steep source number-flux relation, causes more intrinsica...

We present a powerful new tool to analyse and disentangle the 3-D geometry and kinematic structure of gaseous nebulae. The method consists in combining commercially available digital animation software to simulate the 3-D structure and expansion pattern of the nebula with a dedicated, purpose built rendering software that produces the final images and long slit spectra which are compared to the...
