Why do we Need Quality Articles, What are we Going to do With?

I welcome you to this second issue for the year 2011 comprising very interesting articles to read. We are proud to inform about the inclusion of our journal in SCImago Journal Ranking [SJR] recently. SJR is one of the two major journal rating systems that exist in the world: the Journal of Citation reports by ISI-Thomson and the SCImago indexes issued by Elsevier. The SCImago Journal and Country Rank portal is developed by SCImago Research Group working at three Spanish universities (Consejo Superior de Investigaciones Científicas (CSIC), University of Granada, Extremadura, Carlos III (Madrid) and Alcalá de Henares). It is named after the SCImago Journal Rank Indicator (SJR) developed by the group. The citation data used is derived from Scopus database and journal rankings are available for journals contained in the Scopus database. The SJR indicator is calculated based on three year’s citation data and attributes different weight to citations depending on the prestige of the citing journal. The prestige of a journal is estimated using PageRank algorithm in the network of journals. The prestige of a journal is transferred through the references that a journal receives from other journals.[1-3]
