    Over the period of 6 years and three phases, the SEE-GRID programme has established a strong regional human network in the area of distributed scientific computing and has set up a powerful regional Grid infrastructure. It attracted a number of user communities and applications from diverse fields from countries throughout the South-Eastern Europe. From the infrastructure point view, the first project phase has established a pilot Grid infrastructure with more than 20 resource centers in 11 countries. During the subsequent two phases of the project, the infrastructure has grown to currently 55 resource centers with more than 6600 CPUs and 750 TBs of disk storage, distributed in 16 participating countries. Inclusion of new resource centers to the existing infrastructure, as well as a support to new user communities, has demanded setup of regionally distributed core services, development of new monitoring and operational tools, and close collaboration of all partner institution in managing such a complex infrastructure. In this paper we give an overview of the development and current status of SEE-GRID regional infrastructure and describe its transition to the NGI-based Grid model in EGI, with the strong SEE regional collaboration.Comment: 22 pages, 12 figures, 4 table

    Phase Diagram for Roegenian Economics

    We recall the similarities between the concepts and techniques of Thermodynamics and Roegenian Economics. The Phase Diagram for a Roegenian economic system highlights a triple point and a critical point, with related explanations. These ideas can be used to improve our knowledge and understanding of the nature of development and evolution of Roegenian economic systems.Comment: 10 page

    The paper presents pilot experiences related to an educational methodology developed within the European Innovative Teacher (I*Teach) project for building ICT-enhanced skills [1]. The methodology is presented in the context of a workshop for teachers in mathematics and informatics with a special focus on enhancing presentation skills. The authors share their experience in treating the very workshop as a project with specific stages - analyzing the audience’s interests, developing a presentation scenario around a leading metaphor in harmony with the setting, distributing different roles among the presenters, involving the audience in an active reasoning and sharing. Thus the workshop has demonstrated at a meta-level how the collective intelligence of teachers could be harnessed in action. The main message is: such an approach makes teachers feel like co-creators of the I*Teach project´s ideas and teachers need only a bit of praise or encouragement to recognize themselves as innovative teachers
