This journal provides immediate free access to its content based on the principle that making research freely available to the public promotes the global exchange of knowledge. The journal adheres to the free access definition of the Budapest Open Access Initiative (BOAI): “By open access [to peer-reviewed research], we mean free availability on the public internet, permitting any users to read, download, copy, distribute, print, search, or link to the full texts of these articles, crawl them for indexing, pass them as data to software, or use them for any other lawful purpose, without financial, legal, or technical barriers other than those inseparable from gaining access to the internet itself. The only limitation on reproduction and distribution and the sole role of exploitation rights in this area should be to give authors control over the integrity of their work and the right to be properly recognized and cited.”
