In case of double publication we selected the first publication in time.
Figure 18 (sheet 17) reports the Topic Attractions Scores for "health" and "public health" for the 12 countries with the most publications in the time period 2008 2012.
For each cluster of publications and each time period, the number of publications as a percentage of the total number of publications in the time period is determined.
The proportion of authors who had only single-author publications in the time period (shown in the upper left hand side of each figure) did not change substantially over the three time periods.
The Frontiers platform also includes an evaluation system that allows authors to track the impact of their publications in real time.
Table 1 summarizes the number of nodes and links in the coauthorship network, the number of publications in each time slice as well as the fractional size of the largest connected component (LCC).
Publications in the time interval from 1990 to 2010 were considered.
Because the first publication describing the INSURE procedure appeared in 1990, publications in the time frame between January 1990 and June 2013 were sought.
We also determined the proportion of review publications for the 20 countries with the most publications in the time period 2008 2012.
Authors with no links (i.e., one or more single-author publications in the time period) are placed in the upper left hand corner.
