Studies have mainly focused on strategies to motivate teachers or the student-teacher motivation relationships rather than teacher demotivation in the English as a foreign language (EFL) teaching process, whereas no data have been found on the factors that cause teacher demotivation in the Turkish EFL teaching contexts at the elementary education level. Thus, this study aims to investigate the ...
Production and Perception of EnglishTense/lax Vowel Contrastsby Korean EFL Learners
Storytelling is a practical and powerful teaching tool, especially for language learning. Teachers in language classrooms, however, may hesitate to incorporate storytelling into language instruction because of an already overloaded curriculum. English foreign language (EFL) teachers in Taiwan report additional problems such as having little prior experience with integrating storytelling into la...

In gradient scaffolds, changes in porosity, pore size or chemical composition occur gradually. Recently, different methods have been applied to create gradient in the scaffolds, but they have some disadvantages such as high cost and control. The main purpose of this research was to fabricate porous gradient scaffolds by a novel, functional, simple, and low-cost method. Two homogenous scaffolds...
abstract among activities that can be used to prevent piping phenomena and reduce seepage and exit gradient are installation of cutoff wall and drain under hydraulic structures. hence in this study, to investigating the influence of each mentioned parameter on uplift force and exit gradient a computer model has developed in which general equation of fluid flow into the isotropic and anisotropic...
With respect to importance of the conjugate gradient methods for large-scale optimization, in this study a descent three-term conjugate gradient method is proposed based on an extended modified secant condition. In the proposed method, objective function values are used in addition to the gradient information. Also, it is established that the method is globally convergent without convexity assu...
In this paper, an efficient conjugate gradient method for unconstrained optimization is introduced. Parameters of the method are obtained by solving an optimization problem, and using a variant of the modified secant condition. The new conjugate gradient parameter benefits from function information as well as gradient information in each iteration. The proposed method has global convergence und...
The study of elevational diversity gradients dates back to the foundation of biogeography. Although elevational patterns of plant and animal diversity have been studied for centuries, such patterns have not been reported for microorganisms and remain poorly understood. Here, in an effort to assess the generality of elevational diversity patterns, we examined soil bacterial and plant diversity a...
