The table below summarizes the publications plotted on the Map of Science. Each row corresponds to a (sub)discipline on the map

The # of pubs. column shows how many of the publications were mapped to each (sub)discipline. This count can be fractional because some publication venues are associated with more than one (sub)discipline. Each publication in such a venue contributes fractionally to all associated (sub)disciplines according to a weighting scheme.

The % of activity column shows what proportion of the publications were mapped to each (sub)discipline.

This visualization is based on the publications we were able to 'science locate' for Perna, Nicholas, and therefore it may not be fully representative of the overall publication activity for Perna, Nicholas.

The publication coverage of this visualization can be improved by including more publication data in the VIVO system, and by ensuring that each publication in the VIVO system is associated with a journal that the Map of Science recognizes (based on the holdings of Clarivate Analytics' Web of Science database and Elsevier's Scopus database). Journal names containing typos or other idiosyncrasies may need to be cleaned up before they are recognized. You may contact a VIVO system administrator if publication coverage is a concern.
