- The Cultural Journeys in the Information Society is a dynamic hypermedia environment, which proposes the Electronic Roads as a meta-form for exploring cultural information that can form Cultural Journeys. The Electronic Roads meta-form facilitates travelers to explore the information space in a natural and continuous way similar to the exploration of physical roads. This meta-form is advantageous over existing cultural exploration approaches, which usually apply only to discrete information spaces, failing to provide users with continuous explorations and as a result users may lose their intended destinations. The proposed environment provides extendable cultural and historical content for three Mediterranean countries, i.e. Cyprus, Jordan and Egypt. Such a system could be ideal for teaching history and culture; therefore several Learning Activities have been developed in this context. The learning effectiveness of the environment was evaluated in primary schools in Cyprus, where pupils were asked to complete specific Learning Activities by either using the Cultural Journeys in the Information Society environment or a static hypermedia system. The results showed that the pupils found our environment to be easier to use, compared to the static system and that the performance of the pupils that used it was significantly higher.

- Background: Several studies of the dystrobrevin-binding protein 1 gene (DTNBP1), neuregulin 1 (NRG1), D-amino-acid oxidase (DAO), DAO activator (DAOA, G72), and metabotropic glutamate receptor 3 (GRM3) genes have suggested an association between variants of these genes and schizophrenia. Methods: In a replication attempt, single-nucleotide polymorphisms of the DTNBP1, NRG1, DAO, DAOA, and GRM3 genes were analyzed in three independent Scandinavian schizophrenia case-control samples. Results: One DTNBP1 and three GRM3 single-nucleotide polymorphisms showed nominal significant associations to the disease. However, after correction for multiple testing, there were no statistically significant allele, genotype or haplotype case-control differences. Conclusions: The present Scandinavian results do not verify previous associations between the analyzed DTNBP1, NRG1, DAO, DAOA, and GRM3 gene polymorphisms and schizophrenia. Additional studies and meta-analyses are warranted to shed further light on these relationships. Copyright (C) 2009 S. Karger AG, Basel
