Based on the controversial beliefs among L2 teachers about effective corrective feedback (CF) strategies, recast and prompts as 2 kinds of CF have drawn the attention of L2 researchers(e.g., Braidi, 2002; Iwashita, 2003; Loewen & Philp, 2006; Panova & Lyster, 2002; Sheen, 2004). Despite these numbers of studies, debate continues to exist about their usefulness as a CF technique. Whereas recasts...

Abstract This study examined the effect of two types of feedback, post-text as a written feedback and recast as an oral one on written grammatical accuracy of Iranian intermediate EFL learners. To this end, 45 intermediate students who were studying at Ideal Language Institute in Sari were selected based on their performance on the Nelson proficiency test, and then divided into three groups (tw...

Perioperative antimicrobial prophylaxis has been a time-honored principle in the prevention of surgical site infection. Its effectiveness has recently been questioned. Potential reasons for the lack of demonstrable efficacy and suggestions for re-examination of this concept are presented.

We introduce an algorithm that generates an optimal controller for stochastic nonlinear problems with a periodic solution, e.g. locomotion. Uniquely, the quantity we approximate is neither the Value nor Policy functions, but rather the stationary statedistribution of the optimally-controlled process. We recast the control problem as Bayesian inference over a graphical model with a ring topology...

In a recent paper Iri showed that the Iri{Imai method converges in O(nL) iterations to an optimal solution. This is achieved by proving that in each iteration the (multiplicative) barrier function is reduced by (at least) some constant factor (smaller than one). In his paper Iri adopts the 'kernel{index tensor notation with Einstein's summation convention for the coordinate indices'. This notat...

Introduction: To study sentence comprehension in Persian-speaking Patients with Aphasia considering the factors of complexity. Methods: In this cross-sectional study, the performance of 6 non-fluent aphasic patients were tested and their performance was compared to 15 matched control group. Comprehension of semantically reversible sentences was assessed using a binary sentence-picture matching...
