this study investigated the potential role of age in inductive and deductive grammar learning among iranian foreign language learners. the experimental population consisted of our randomly selected samples including two groups of children (with age of exposure to english within 8-13), and two groups of adults (with age of exposure to english within 11-13). thus, the comparison was between ch...
A method is proposed for estimating the relationship between a number of variables; this differs from regression where the emphasis is on predicting one of the variables. Regression assumes that only one of the variables has error or natural variability, whereas our technique does not make this assumption; instead, it treats all variables in the same way and produces models which are units inva...
the current study aimed at investigating the relationship between motivation and test preparation strategies (tpss) used by iranian pre-university students in their preparation period for the university entrance exam (uee). due to the importance of uee in iran, this study also attempted to show its impact on these two important variables. to this end, 100 pre-university students in an iranian p...
target tracking is the tracking of an object in an image sequence. target tracking in image sequence consists of two different parts: 1- moving target detection 2- tracking of moving target. in some of the tracking algorithms these two parts are combined as a single algorithm. the main goal in this thesis is to provide a new framework for effective tracking of different kinds of moving target...

learning-oriented assessment seeks to emphasise that a fundamental purpose of assessment should be to promote learning. it mirrors formative assessment and assessment for learning processes. it can be defined as actions undertaken by teachers and / or students, which provide feedback for the improvement of teaching and learning. it also contrasts with equally important measurement-focused appro...
Sustainable development is rapidly moving from the periphery to the mainstream of politics, business, and science. Over the past several years, a strong consensus has started to emerge that some major global problems can only be overcome through largescale concerted action. Recent additions to the debate include the reports by the International Panel on Climate Change, the Stern Report on the e...
The 1989 Nobel Prize in chemistry has been awarded to Sidney Altrnan and Thomas R. Cech for their discovery that RNA in living cells can function not onfy as a molecule of heredity, but also as a biocatalyst. A brief historical overview of the laureates’ work is presented, and citation data for their most-cited publications are examined. Research-front analysis highlights both scientists’ centr...
Abstract The exponentially growing number of scientific papers stimulates a discussion on the interplay between quantity and quality in science. In particular, one may wonder which publication strategy offer more chances success: publishing lots papers, producing few hit or something between. Here we tackle this question by studying portfolios Nobel Prize laureates. A comparative analysis diffe...
