This study tried to find out what factors underline the characteristics of acquisition of English language in EFL classrooms. To this end, the Characteristics of English Language Acquisition Scale (ELAS) consisting of 41 items was designed by the researchers of this study and administered to 388 pre University Iranian EFL students at various private and public schools in Neyshabour and Zebarkha...

in this research، job opportunities have been examined among 26 productive sectors of iran's economy by using input-output table in 2001.from viewpoint of employment ،production and value added، the key sectors has been diagnosed by using mri ، elasticity of input-output table، backward and forward linkages and june's corrective methods. then، job opportunities has been analyzed among...

We study the dynamics of the manufacturing component of GDP. We first document that the output growth rate for the majority of sectors and their aggregates is different (asymmetric) in recessions and expansions. Compared to expansions, recessions are deeper deviations from trend and have shorter expected duration. This finding raises a basic question that we address in this paper. Which factors...

one of the most problematic areas in foreign language learning is collocation. it is often seen as arbitrary and an overwhelming obstacle to the achievement of nativelike fluency. current second language (l2) instruction research has encouraged the use of collaborative output tasks in l2 classrooms. this study examined the effects of two types of output tasks (editing and cloze) on the learning...

control of production processes in an industrial environment needs the correct setting of input factors, so that output products with desirable characteristics will be resulted at minimum cost. Moreover, such systems havetomeetset of qualitycharacteristicstosatisfycustomer requirements.Identifyingthemosteffectivefactorsindesignoftheprocesswhichsupportcontinuousandcontinualimprovement isrecently...

Cointegration analysis is applied to the linear combinations of the time series of (the logarithms of) output, capital, labor, and energy for Germany, Japan, and the USA since 1960. The computed cointegration vectors represent the output elasticities of the aggregate energy-dependent Cobb-Douglas function. The output elasticities give the economic weights of the production factors capital, labo...

The paper by Dan Andrews and Marion Kohler provides an interesting and very useful contribution to the empirical literature that seeks to explain the factors infl uencing bilateral output correlations. While there are a number of papers that have developed empirical models of the cross-section distribution of bilateral (de-trended) output correlations (Baxter and Kouparitsas 2005, Imbs 2004 and...

The maximum cardiac output that can be achieved during exercise might be limited either by extracardiac factors influencing ventricular filling, or by the heart itself. In order to investigate this problem, the effect on the cardiac response to maximum exertion of an acute expansion of blood volume was studied in six men with essentially normal cardiovascular systems. Augmentation of blood volu...
