One of the most important aspects in the social activity of people, Education, could not be an exception. Advances in network infrastructures and telematics services, combined with multimedia techniques and powerful personal co...

We present a system of cueing informal interactions using the combination of Bluetooth hardware addresses to identify people and a database of user profiles. We outline the synergies between the mobile and social software infrastructures, and present a novel architecture for instigating face-to-face interaction designed to meet varying levels of privacy requirements. Finally we present a discus...

For this purpose, bibliometric analysis was used documents obtained from WoS database, and selecting combination of words “green infrastructures”, “ecosystem services”, “climate change”. The r...

The Seamless Access to Multiple Datasets (SAMD) project is designed to demonstrate the benefits of Grid (e-Science) technologies for dataset manipulation and analyses in a social science context. Grid technologies run over existing internet infrastructures and offer a faster alternative to the world wide web for the transfer and analysis of large datasets. Under the SAMD project, a web-delivere...

Human computation includes the accumulation of social wisdom in the form of progressive social agendas.
