Open access to scientific articles and publishing costs

"Think for a moment the following situation: a significant portion of the world's scientific research is publicly funded, conducted by researchers working in public institutions and receive salaries or grants originating studies of public money. As a result of this research, are produced scientific journal articles that governments, public institutions and society in general need to pay for access to these articles, fruits of public funding. Does it make sense? It is. Capes, for example, funds a large portion of the scientific research in Brazil and need to spend about 65 million dollars annually to over 300 institutions, including universities and research institutions, have access to about 25 000 titles of scientific journals through Journals Portal Capes. This situation has been widely discussed in academic circles today, creating a movement 'Open Access (OA)', which aims to encourage scientific publishing in open access journals. The NIH ( National Institutes of Health ), which stand searches in health care in the United States requires that all NIH-funded research be made ​​available as open access. As a result of this movement, which seems irreversible, we can observe an increasing number of journals that are offering their content for free on the internet, and passing the 'burden' to the authors of published articles. Yes, because there is a cost behind the periodicals, ranging from room rentals, salaries of secretaries to the typesetting and publishing. Furthermore, let the innocence aside: many publishers, such as Elsevier famous, are in this to make money. Thus, it is increasingly common to find journals that charge a 'submission fee', ie a fee to just parse the article, which can be accepted or not. And if accepted, then comes the 'published rate' usually charged by the article page in its final form. In this new world of free access to scientific papers, published articles will come out more expensive. And the result will be that all teachers, researchers and graduate students will apply for financial aid for graduate programs or the funding agencies to pay for the publication of research. Or put these publication costs in the budget of the projects. And once more public money will fund the publication of scientific articles. However, the fundamental difference is that at least they will be available for the whole society."
