“…The impact factor deserves special attention due to its importance and because it is the indicator preferred by academia. It is the bibliometric indicator used by the ISI and the CAPES, and is calculated by dividing the total number of citations in any given year of articles from a specific scientific journal, published over the previous two years in a specific set of scientific journals (in this case, ISI's scientific journal database), by the number of scientific articles published by the same scientific journal during the same period (Campos, 2003;Garfield, 1999;Medeiros, 2003;Saha et al, 2003;Tahai & Meyer, 1999;Vilhena & Crestana, 2002), as shown in Table 1, regarding a hypothetical Journal Y. Some authors have criticized the use of the impact factor to assess scientific journals (Campos, 2003;Coelho et al, 2003;Coura & Willcox, 2003;Uncles, 2004).…”
