Data Envelopment Analysis (DEA) is an eciency measurement tool for evaluation of similar Decision Making Units (DMUs). In DEA, weights are assigned to inputs and outputs and the absolute eciency score is obtained by the ratio of weighted sum of outputs to weighted sum of inputs. In traditional DEA models, this measure is also equivalent with relative eciency score which evaluates DMUs in compar...

Since data envelopment analysis (DEA) introduced in 1970s, it has been widely applied to measure the efficiency of a wide variety of production and operation systems. Recently DEA has been extended to examine the efficiency of decision making units (DMUs) with two-stage network structures or processes, where the outputs from the first stage are intermediate measures that make up the inputs of t...

The current study is an attempt to investigate the impact of decision-making (selecting and matching) tasks and production (creation of sentences and completion of sentences) tasks on the collocational knowledge of Iranian intermediate EFL learners. To this end, sixty EFL learners were divided into two experimental (decision-making and production) groups. To determine the effects of the tasks, ...

This study aimed at investigating the effect of instructional YouTube videos on Iranian male and female EFL learners' listening comprehension. It was conducted with 60 male and female intermediate male and female EFL learners. The Oxford Quick Placement Test (OQPT) was used to measure the participants’ language proficiency to make sure about homogeneity of the participants. The participants wer...

The main purpose of the present quasi-experimental study was to investigate the effects of linear process versus genre-based approach on EFL learners’ written production. To this end, 40 learners of English at intermediate level were randomly selected as the participants of the study and assigned into two groups of experimental (process and genre) which received different types of instruction f...

Vershik’s standardness criterion takes a particular form in the case of rn-adic filtrations, which we call Vershik’s intermediate level criterion in this paper. This criterion whose nature is combinatorial has been intensively used in the ergodic-theoretic literature, but it is not easily applicable by probabilists because it is stated in a language proper to the theory of measurable partitions...

The purpose of this study was twofold. Firstly, it attempted to investigate whether language learning strategies (LLSs) can predict foreign language (FL) proficiency. Secondly, it examined what kind of LLSs Iranian learners of English use more frequently in FL institutes. To do so, 112 intermediate Iranian EFL learners participated in the study. Oxford’s Strategy Inventory for Language Learning...

The research reported here examined the relative effectiveness of semantic mapping, as an interactive pre-reading strategy, on reading comprehension of Iranian undergraduate students (non-EFL majors). It also examined whether there was an interaction between gender and the effect of teaching semantic mapping strategy on reading comprehension. The participants in this study consisted of 120 male...

This study set out to explore whether different input enhancement tasks as implicit instruction techniques had any significant impact on the intake of causative verbs in English as a foreign language among Iranian EFL learners. For this purpose, three intact classes consisting of 75 male and female intermediate L2 learners were randomly divided into three conditions: simultaneous grammar consci...

Researches show that the strength criterion is inadequate for design of structures against seismic loads. Since structures yield and experience plastic deformation under strong ground motion, considering structural damage with inelastic behavior may be a considerable criterion for design and control of the structures.In this paper, three steel structures with dual system consisting of intermedi...
