Example text

At first sight, this does not appear to be correct. However astronomy appears to be an exception. In this field, Astrophysical Journal and Astronomy & Astrophysics are the two journals with the largest number of articles (2,435 and 1,936, respectively – black squares) and, as can be observed in Figure 5, these are the journals where most Brazilian astronomers have published. This pattern does not apply to immunology and oceanography. In the first two journals in the immunology LNA ranking, Journal of Experimental Medicine (n ¼ 1; 603) and Transplantation (n ¼ 1; 154), Brazilians have published fewer than 20 articles in the five years studied (white triangles).

S. s. s. s. s. s. s. s. s. 50 Notes: *Significant positive contribution to LOG; ** Significant negative contribution to LOG Collaboration characteristics The quadratic relationship of LOG to number of authors (A) and addresses (D) indicated by the multiple linear regression is shown in Figure 1. It shows an increase in potential citations with larger collaborating groups of institutions. An increase in the number of authors per paper also increases potential citations. The effect saturates at five authors, falling thereafter with larger numbers of authors.

Details of the most highly cited publications from each of the three fields are presented in Table VII. The cumulative number of citations of these publications differs among the fields. In immunology, the range of citations of the top-cited publications was higher than that found for the top-cited publications from astronomy which were in turn more highly cited than those from oceanography. The type of publication also varies. In astronomy and oceanography, there are “reviews” and “notes” or “letters” among the most cited publications, while in immunology there are only “articles”.
