the present study intended to look into and compare the possible effects of competitive team-based learning (ctbl) with learning together (lt) or cooperative group-based learning (cgbl) – the most popular method of cooperative learning (cl) -- on oral performance of iranian efl intermediate students. after administering the oral interview, this researcher selected a group of 40 almost homogeneo...

A new class of chiral bifunctional heterogeneous materials composed of Au/Pd nanoparticles and chiral phosphoric acids as active orthogonal catalysts was prepared by utilizing a facile pseudo-suspension co-polymerization method. It was found that this heterogeneous catalyst was capable of facilitating the sequential aerobic oxidation-asymmetric intramolecular aza-Friedel-Crafts reaction between...

A number of multi-priority jobs are to be processed on two heterogeneous processors. Of the jobs waiting in the buffer, jobs with the highest priority have the first option of being dispatched for processing when a processor becomes available. On each processor, the processing times of the jobs within each priority class are stochastic, but have known distributions with decreasing mean residual...

In this paper, we present the first end-to-end fairness analysis of a network of fair servers. We argue that it is difficult to extend existing single-node fairness analysis to an end-to-end analysis of a network where each node may employ a different fair scheduling algorithm. We then present a two-step approach for end-to-end fairness analysis of heterogeneous networks. First, we define a cla...

The present century is the era of information and communication, and learning English language can pave the route; however, some young learners face psychological barriers in English classes. This research was done to compare the efficiency of TBILT and TBLT on the youth’s morale of inquiry. The statistical population included all 4200 Babol Azad University students of whom 320 were volunteers ...

This paper analyses the Marxian theory of exploitation. A general axiomatic approach is developed which is appropriate to study the concept of exploitation what it is and how it should be captured empirically. Two properties are presented that capture some fundamental Marxian insights. It is shown that, contrary to the received view, there exists a nonempty class of definitions of exploitation ...
