These notions are operationalized by counting citations (whole counts in the Web of Science) for articles published during the period 2008 to 2011. Care has been taken to obtain clean data by careful institutional name disambiguation. It is found that, especially for large fields, more than 80% of top scientists work at top organizations. This is less the case for smaller fields such as mathematics and computer science. Our research confirms the skewness (elitism) of science, also for the relation between first rate scientists and the organizations to which they belong. We find, moreover, that top institutions have relatively more excellent scientists and relatively fewer researchers with poor performance than the average level of all institutions in a field.

It is shown that their contribution is growing exponentially. In 2013 almost one fifth of all publications in this journal had at least one Chinese author. The average number of citations per publication is approximately the same for articles with a Chinese author and for articles without any Chinese coauthor. Using the odds-ratio, we could not find arguments that Chinese authors in PLOS ONE excessively cite other Chinese contributions.

This is shown by a construction where adding the same number of articles with the same number of co-authors to two existing groups (with a given number of articles with one or two collaborators) reverses the original order in these groups' bonding numbers.

More precisely, we propose two different types. For the first type, sources are years, and items are either publications, or citations received or citations per publication. The second type makes use of the speed by which citations are received: it is a diffusion speed index.

Taking into account both the publications that have a direct influence and those that have an indirect influence, we obtain the total influence measure on a fixed paper.
