Global Author Distribution gives an indication of the countries where the authors for a journal are based. The world map above shows the percentage number of authors by country during the year lifetime of the journal, where the color for a particular country is a measure of the percentage of authors from that country (hover over the map to see the more information of authors and how that country ranks in terms of authorship compared to other countries).
Tecno Scientifica journals are generally international by nature and therefore have a global authorship. Authors publish research articles from all over the world and collaborate with peers at different institutions in different countries. This metric intends to visualize the geographical spread of a journal's authorship and the relationships between countries for which the journal has relevance.
