Usually writing teachers feel commitment to provide their learners with corrective feedback (CF) to their linguistic errors. The study investigated whether two types of written corrective feedback, indirect focused corrective feedback and indirect unfocused corrective feedback, produced differential effects on the accurate use of grammatical forms by high intermediate EFL learners. In this stud...

We consider the properties of certain graphs based on iteration of the quadratic maps x→ x2 and x → x2 − 2 over a finite field GF (p).

While research has mostly focused on the pragmatics of variable tag questions, fewer studies have explored invariable tags, either for their own sake or in contrast with other types within and across languages. It will be argued that questions are as much part question system a unified functional model needs to consider both order compare function-to-form mappings reveal language variation, wel...

in this paper, the problem of decentralized model reference adaptive control (mrac) for a class of large scale systems with time varying delay in interconnected term and input and state delays is studied. to compensate the effect of input delay indirectly, a smith predictor built on. to handle the effects of the time delays in input, the adaptive controller part includes two auxiliary dynamic f...

A novel method for feature selection and construction is introduced. The method improves the classification accuracy, utilizing the well-established technique of grammatical evolution by creating non-linear mappings of the original features to artificial ones in order to improve the effectiveness of artificial intelligence tools such as multi-layer perceptron (MLP), Radial-basis-function (RBF) ...

The computational implementation of a linguistic theory of the representation and projection of grammatical features in nominals is described. The processing of nominals is part of a larger model of language comprehension implemented as a computational cognitive model within the ACT-R cognitive architecture. The model combines a serial, pseudo-deterministic processing mechanism for building lin...

whether or not there is a verbal passive construction in persian has been ‎highly controversial. traditional grammarians and most linguists have ‎argued that there is a structural passive construction in persian, similar to ‎that observed in english. within the framework of the minimalist ‎program, but more in the spirit of emonds’s (2006) division of analytic ‎passives into verbal and adjectiv...
