referential transparency

[mei]

Hi,

Could anyone help me with the pharse 'referential transparency' in the following paragraph? Thanks a lot.

In attempting to prioritize for discussion the ‘objective’ journalist’s claim of referential transparency, this issue of how relations of patriarchy inform the ‘discipline of objectivity’ as seemingly apolitical (genger-neutral) normative ideal is critical.

I would guess that it means one has declaired all their sources for the material they are writing.
