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 اولself-revision and third party revision in translation
اهمیت این پژوهش در آن بود که به گفت? بسیاری از پژوهشگرانِ حوز? بازبینی ترجمه، ادبیات موجود در این زمینه به لحاظ نظری و عملی چندان قوی نیست و بخش های موجود نیز برداشت مناسبی از این مرحل? فرایند ترجمه ندارند، اگرچه اخیراً توجه به آن به صورت نظام مند افزایش یافته است. در عین حال، پژوهش های موجود از یک سو بر دگربازبینی بیشتر از خودبازبینی تأکید دارند و از دیگر سو تنها به لحاظ نظری به این موضوع می پرد...
15 صفحه اولShielding studies on a total-body neutron activation facility
Background: Prompt gamma neutron activation analysis (PGNAA) is known as a non-invasive technique capable of measuring elemental concentration in voluminous samples in a short period of time. Also it is a valuable diagnostic tool for total body elemental measurements. 252Cf and 241Am-Be sources which are usually used in this method, generate not only neutrons, but also emit high-energy and unwa...
