This study investigated the impact of writing checklist on composing descriptive essays among EFL learners at the intermediate level. Sixty participants were assigned to experimental and control groups. Both groups were given a pre-test of writing a descriptive essay including 150 words. The experimental group used checklist for learning while the control used teacher correcting technique in ea...

The present study set out to determine the effect of implementing exploratory-cumulative talk in comparison to disputational talk on cognitive (meaning development and organization of thought as well as problem solving ability) dependency of intermediate level students in translation studies. In order to achieve the objectives of the study, a quasi-experimental-pretest-posttest-statistical stud...

this study focuses on the relationship between lower-intermediate level efl learners’ metacognitive awareness and accuracy in self-assessment of a speaking test. we tried to raise the learners’ metacognitive awareness through practice in goal-setting and planning. to do so, 103 lower-intermediate level students took a pretest of speaking, completed a metacognitive awareness questionnaire, and h...

The aim of this study is decomposition of the changes in energy consumption with emphasizing the structural changes in Iran during 2001-2011 using Input- Output Structural Decomposition Analysis (I_O SDA). Structural changes in this study represent the changes in structure of intermediate input in sectors and also changes in structure of final demand categories. Structural changes in intermedia...

A new part segmentation approach is presented which works on real images. These images contain 3D objects with textures and shadows on a complex background. The proposed approach relies on the outline of the object to guide the grouping of lines using symmetry and colinearity principles. This grouping of lines leads to simple shapes which can be modeled by 3D primitives such as geons or general...

We investigate some simple and surprising properties of a one-dimensional Brownian trajectory with diffusion coefficient D that starts the the origin and reaches X either: (i) at time T or (ii) for the first time at time T . We determine the most likely location of the first-passage trajectory from (0, 0) to (X,T ) and its distribution at any intermediate time t < T . A first-passage path typic...

Medical physics is currently a rapidly growing field of physics. Numerous academic, clinical and industrial opportunities are open to physicists in the medical world. I report on an intermediate level physics course on medical physics taught at Carleton College. The topics covered in this course cover all areas of physics, but with examples drawn from medical applications. In addition to physic...

In a society, a proportion of the individuals can benefit from creativity without being creative themselves by copying the creators. This paper uses an agent-based model of cultural evolution to investigate how society is affected by different levels of individual creativity. We performed a time series analysis of the mean fitness of ideas across the artificial society varying both the percenta...
