Scientific output of AIMS Research Centres

The number of publications from AIMS Research Centres is rising strongly, in correspondence to the overall growth AIMS has experienced in recent years.

The figure below illustrates this growth from 2010 until 2014. During this period the output has grown by an average factor of 1.8 per year. Between 20% to 30% of the scientific output is from visiting researchers.

Citations

As the output of papers by AIMS has been rising, so has the cumulative number of citations AIMS’ papers have received (1624 on 30 June 2015). The indicator of interest though is the average number of citations per paper, which is 7 citations per paper. Another key indicator is the h-index, which is 19. This indicates that AIMS researchers have published 19 documents that have been cited at least 19 times.

Journals

The Source Normalised Impact per Paper (SNIP) is a comparative indicator of the impact of journals. SNIP is the ratio of a source’s average citation count per paper and the citation potential of its subject field. A SNIP value that is higher than one means that the journal has an above average SNIP for its field. A SNIP that is lower than one means that the journal has a below average SNIP for its field. If SNIP is equal to 1, the journal is absolutely average for its field.
