According to me quality of a scientific paper should be assessed in terms of personal satisfaction and help it would provide to the scientific community, as well as the common people.
My quality definition of scientific paper is the peer review system, without it is just propaganda, but, at the same time, in the academic world there is a big debate about it. How is possible that an "expert" can determinate the quality of a paper (and its researche) just reading in a short time, when the researcher (author) has been working in this topic for a lot of years. Is very polemic.
In 2007 Uwe Flick wrote: "discussions of the quality of qualitative research are located at the crossroads of internal and external challenges". What is triggering in that quote, that it gives the quality questions to opposite directions: internal and external criteria. The internal dimension has to do ask if disciplinary standards have been respected or brought further, credibility is probably linked to the systematic respect of methodic standards, whereas the external one is concerned with questions of generalizability, applicability, practical relevance etc. So there is probably more than way a research paper can be of high quality. A paper can be very rigorous, but irrelelvant, highly relevant and original, but lacking of methodological rigour and so it is not credible. etc
Good answer. Sometimes, what bothers me is the fact that we have been pushing to publish in English, but the vast majority of the Brazilian population can not read this language. This means that we are not doing research for Brazilians in Brazil?
