different researchers in different parts of the world have investigated the strategies used to translate written works ranging from novels to classroom assignments. however, by the significant increase in the number of postgraduate students in iran in the last few years, a very common kind of translation in iran includes translating abstracts of master’s theses. in this work, the researcher hav...
Background: This study tested the null hypothesis that nonoperatively treated patients would not show disease progression of carpal tunnel syndrome (CTS) over time according to median nerve distal motor latency (DML) on two electrodiagnostic tests. Methods: This retrospective study analyzed sixty-two adult nonoperatively treated patients who were diagnosed with CTS confirmed by a minimum of...
the present study was an attempt to compare the effect of peer metalinguistic corrective feedback on elementary and intermediate efl learners speaking ability to see which level benefits more from this type of feedback. to this end, 117 female efl learners at grade 3, al-zahra high school in kermanshah, iran were non-randomly chosen. the homogeneity of the participants was attained through a pi...
Three predictions were derived from the assumption that with increased age there is a decrease in the effective signal-to-noise ratio of neural representations of visually presented stimuli. Although the results from manipulations designed to examine the internal consistency ofthe predictions were quitC positive, the predicted age differences failed to appear in two of the three dependent measu...
When evaluating differences between competing precipitation forecasts, formal hypothesis testing is rarely performed. This may be due to the difficulty in applying common tests given the spatial correlation of and nonnormality of errors. Possible ways around these difficulties are explored here. Two datasets of precipitation forecasts are evaluated, a set of two competing gridded precipitation ...
We observe a sequence of test statistics 9~ = (Tlt T2,..., 7}), each of which is approximately N(0,1) under the null hypothesis Ho, but which are correlated with each other. Not being certain which 7} is best, we use the test statistic 7 ^ = maxfTj, T2,...,Tj}. For a given observed value of 7 ^ , say c, what is the significance probability pr(7^iax > c)? Define the length of 9~ to be E ' ^ a r ...
within the components of communicative competence, a special emphasis is put on the “rules of politeness,” specifically the politeness strategies (brown and levinson, 1978) that speakers deploy when performing the request speech act. this is because the degree of imposition that making a request places upon one’s interlocutor(s) has been seen to be influenced by several factors among which, as ...
