this study aims to investigate the relationship between information literacy, computer self-efficacy and academic performance in a population of 1054 of ba and ma students of psychology and educational sciences faculty of tehran university. the data are collected in a sample of 283 students (103 ba and 180 ma); selected using cochran's sampling formula. these students answered mittermeyer ...

the aim of this research is survey of bandura theoretical foundation of self efficacy include psychological, social, and philosophical base. in this research use analytic – deduction research method to achieve the aim. thus as psychological basis, the concepts of reciprocal determinism, consciousness, learning and finally the human agency will be discussed. under the social basis the effect of ...

By evolving self-reproducers, found in two-dimensional Cellular Automata rules, we obtain fractal-like objects. This paper focuses on analyzing the fractal features of different self-reproducers and provides a perspective on how it is possible to translate into music some creative processes self-reproducers show, which are similar to the counterpoint method. Many self-reproducers are tied toget...

This study proposes an innovative measure for evaluating the performance of text clustering. In using K-means algorithm and Kohonen Networks for text clustering, the number clusters is fixed initially by configuring it as their parameter, while in using single pass algorithm for text clustering, the number of clusters is not predictable. Using labeled documents, the result of text clustering us...

We present a method to reduce a formal context while retaining much its information content. Although simple, our ICRA approach offers an effective way to reduce the complexity of concept lattices and / or knowledge spaces by changing only little information in comparison to a competing model which uses fuzzy K-Means clustering.

Emergent self-organizing maps (ESOMs) and k-means clustering are used to cluster counties in each of the states of Florida, Pennsylvania, and Ohio by demographic data from the 2010 United States census. The counties in these clusters are then analyzed for how they voted in the 2008 U.S. Presidential election, and political strategies are discussed that target demographically similar geographica...
