bullying is a kind of peers’ altercation which usually occurs in schools. it seems to be a universal phenomenon that can be observed almost in all classrooms. since the expansion of information and communication technologies, there have been social concerns related to negative effects of these networks, especially in adolescents. in this paper which documentary methodology by referring to execu...

  Purpose: Different views of an individuals’ image may be required for proper face recognition.   Recently, discrete cosines transform (DCT) based method has been used to synthesize virtual   views of an image using only one frontal image. In this work the performance of two different   algorithms was examined to produce virtual views of one frontal image.   Materials and Methods: Two new meth...

The paper discusses methods, forms and safety issues of social network usage for school students. Taking into consideration the growing interest of students to electronic communication in social networks (ESN), it was described their place in the information educational environment. There were made the classification of objects and use of ESN to help teachers and school authority to teach stude...

Despite many works on collaborative networked organizations (CNOs), CSCW, groupware, workflow systems and social networks, computer support for virtual teams is still insufficient, especially support for agility, i.e. the capability of virtual team members to rapidly and cost efficiently adapt the way they interact to changes. In this paper, requirements for computer support for agile virtual t...

Proposed interdisciplinary work presents conceptual framework for the simulation of information-based social networks. Some new principles and approaches are introduced. This paper, however, concentrates more on one key aspect, i.e. virtual computational field approach (VCF). In fact, VCF constructs a virtual medium for information and resources exchange between heterogeneous social agents. Soc...

regulations of use of social networks, as one of the key components in these networks, serve an important role in controlling the flow of traffic. the study of the harmonization of these terms and regulations can be a significant step to avoid congestion and (users’) rejection in the network. harmonization of traffic control regulations (tcr) among social networks is one of the best solutions...

Background: As social networks are increasingly used, the research published through social networks should be evaluated. Hence, new measures were employed to examine the scientific effectiveness of social networks. The measurements taken from social networks, called Altmetrics, provide an opportunity to evaluate research. Therefore, this study aimed to investigate the presence of indexed artic...
