Direct users of the information Apheis produces and disseminates include the scientists who appear just to the right of the Apheis box and who receive information directly from Apheis. These scientists in turn pass that information on to other scientists and to committees, seen in the box further to the right, all of whom thus become pass-on users, because they receive the information Apheis produces indirectly from Apheis. Then, the individual scientists and committees pass Apheis information on to the policy advisors below them, who form another group of pass-on users. And those policy advisors in turn pass the information on to policy makers, who review.
