With the fast development of Internet and WWW, "information overload" has become an overwhelming problem, and collective attention of users will play a more important role nowadays. As a result, knowing how collective attention distributes and flows among different websites is the first step to understand the underlying dynamics of attention on WWW. In this paper, we propose a method to embed a...

Sparse representation based classification (SRC) is popularly used in many applications such as face recognition, and implemented in two steps: representation coding and classification. For a given set of testing images, SRC codes every image over the base images as a sparse representation then classifies it to the class with the least representation error. This scheme utilizes an individual re...

— The big influence of Information and Communication Technologies (ICT), especially in area of construction of Technological Societies has generated big social changes. That is visible in the way of relating to people in different environments. These changes have the possibility to expand the frontiers of knowledge through sharing and cooperation. That has meaning the inherently creation of a n...

This comment on Valsiner’s (2003) theory of enablement appreciates the theory’s contribution to fill the lacuna of social representation theory in dealing with individual reasoning and behaviour through a mechanism of semiotic mediation. It is shown, however, that the experimental illustration of the theory falls slightly short of providing evidence for the claims. In re-interpreting the experi...

Solitons arise as static solutions of finite energy to the equations of motion of non linear field theories. A given solution in general depends upon a set of parameters or moduli, and is a point in the manifold of solutions of equal energy, or moduli space. In many cases this manifold is simply a coset space G/H where G is the group of symmetries of the action and H ⊂ G is the symmetry of the ...

There has been a recent increase in research interest the ways that visual representation is used to facilitate students’ understanding science classrooms. Yet while many studies have explored individual drawing, few looked into drawing as collective tool engage students thinking and talking together This study employed case approach understand some of possibilities for construction reasoning t...

Commercial cinema in Spain, as the rest of world, has gone to great lengths describe visually, without any intention protest, each and every one forms violence against women: physical, psychological, financial, social and, lastly, sexual. Beyond insinuating intimidating compliments gazes, sexual is something that excepted scripts, even those famous directors who create powerful female character...
