Problem is, most of the authors are apparently Brazilian, paid (presumably) by the Brazilian government, and have separate research funding from the same government. A non-Brazilian, English author says two of his three affilitions are with Brazilian universities. There seems to be no other funding aside from a fellowship. 2% of Brazil's GDP comes from cane sugar. Think a pressing national interest, bolstered by research funding from the government, is likely to bias research? If not, then why should industry funding?
