Example text

S. s. s. s. 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.

One common finding is that, although ASTRO research is now increasingly the pursuit of small teams (with a mean number of authors per paper of three or more (Ferna´ndez, 1998)), it still has a fair number of single-author papers. However, most of these scientometric studies used a rather simplistic delineation of the ASTRO field, based on a list of journals. Methodology The filter that we developed was designed to capture ASTRO papers (including ones on the solar system) and was calibrated through a partnership between a subject expert (AB) and a bibliometrician (GL).

1 from 1994 to 2003. 1. This implies that contributions to ASTRO appearing in these journals contribute positively to the mean impact of the field. The impact of journals in chemistry, physics, mathematics and engineering are less than in ASTRO journals (mean LOG , 3), implying that publications appearing in these journals are likely to contribute negatively to the impact of the subject. These are broad conclusions, and do not apply to individual papers. For example, an ASTRO paper appearing in a high-impact physics journal could increase the potential impact of the field.
