While some researchers have questioned the efficacy of corrective feedback (CF), other researchers believe that CF can be effective if implemented through new technology types, including e-portfolio (EP). However, whether EP can be used as a medium of providing CF for language learners at different levels of language proficiency is still unknown. The purpose of the present study, therefore, was...

This study investigated textual and inter-textual reading of a group of Iranian EFL undergraduates’ careful English reading types.

‎This paper proposes a new form of optimization problem which is a two-level programming problem with infinitely many lower level constraints‎. ‎Firstly‎, ‎we consider some lower level constraint qualifications (CQs) for this problem‎. ‎Then‎, ‎under these CQs‎, ‎we derive formula for estimating the subdifferential of its valued function‎. ‎Finally‎, ‎we present some necessary optimality condit...

ABSTRACT- Noise is considered as one of the most debilitating conditions in farming operations. In this study, a number of factors affecting the noise generated by Sampo 3065 combine harvesters were evaluated. Factors were engine speed and gear ratio for combines with and without original cabins. A factorial experiment arranged as a completely randomized design with four replicates was used. Re...

We describe the PerDiS persistent distributed store and its garbage collection algorithm. The PerDiS store behaves like an object-oriented persistent shared memory, and is accessed transactionally. Applications get direct access to persistent data in their own memory, and use the usual C/C++ pointer dereferencing and assignment to navigate and modify the object graph. PerDiS provides persistenc...
