An institution that is wholly owned, operated, administered or contains research facilities for another institution. All affiliations for an affiliated institution are credited to the institution to which it is affiliated.
Affiliated joint institution
A research facility operated jointly by multiple institutions. Each partner institution of the joint institution receives an equivalent fractional count for every affiliation the joint institution is included in.
Affiliated joint institutions and consortia
Represents joint institutions and consortia for which the institution is designated as a partner institution.
Article count (AC)
A count of one is assigned to an institution or country if one or more authors of the research article are from that institution or country, regardless of how many co-authors there are from outside that institution or country.
Indicates research partnerships between multiple institutions. Each partner institution of a consortium receives an equivalent fractional count for every affiliation the consortium is included in. Often consortia are international and in some cases there is no home research facility.
A digital object identifier (DOI) is a unique alphanumeric string assigned by a registration agency (the International DOI Foundation) to identify content and provide a persistent link to its location on the Internet. The publisher assigns a DOI when your article is published and made available electronically.
Fractional count (FC)
A fractional count that takes into account the percentage of authors from that institution (or country) and the number of affiliated institutions per article. For calculation of the FC, all authors are considered to have contributed equally to the article. The maximum combined FC for any article is 1.0.
An institution that funds research and is not responsible for the administration of the research or research itself. Affiliations that are deemed to be from funding institutions do not receive a fractional count. In instances where a funding institution has its own research facilities, those affiliations will receive a fractional count.
The Nature Index is a freely accessible database of author affiliation information collated from research articles published in an independently selected group of high-quality science journals.
The number of research articles tracked by the Nature Index for which a particular institution or country has at least one affiliation. Outputs are counted by article count (AC) and fractional count (FC).
The institutions that together own, operate, administer or have responsibility for research facilities and/or activities at the relevant joint institution or consortium.
The institution responsible for the operation and administration of another institution or research facility.
Macro-subject areas into which outputs are assigned. Research articles are assigned to subjects based on the scientific discipline of the journal in which they are published, with the exception of multidisciplinary journals – Nature, Nature Communications, PNAS and Science. For these journals, subjects are assigned at the article level. Research articles can be assigned to more than one subject.
