If you are translatiing from Japanese to English,
the target language word publicity is used by Rolls,
he used public, publicity and publicness.

By publicity perhaps he meant that it (mainly referring to the nature of information) has an access from, and is open to all members in community, can be known to anyone.
below is references but I recommend reading some John Rolls text.

Rolls is not an American in the first place.
