These The plan's approach towards this goal is populations would then receive particular to identify two aims, one of information management attention, beyond the general gathering or research and one of initiatives that can be recommended for all management. Within each aim are several populations (see Objective 7). The criteria specific objectives. used to determine these key populations AIMS needs further discussion. They are likely to include characteristics of the populations 1.
