Global institutions Apart from regional, country, and liaison offices, the World Health Assembly has also established other institutions for promoting and carrying on research. International Agency for Research on Cancer (IARC) Regional offices The regional divisions of WHO were created between 1949 and 1952, following the model of the pre-existing Pan American Health Organization, and are based on article 44 of the WHO's constitution, which allowed the WHO to "establish a [single] regional organization to meet the special needs of [each defined] area". Many decisions are made at the regional level, including important discussions over WHO's budget, and in deciding the members of the next assembly, which are designated by the regions. Each region has a regional committee, which generally meets once a year, normally in the autumn. Representatives attend from each member or associative member in each region, including those states that are not full members. For example, Palestine attends meetings of the Eastern Mediterranean Regional Office. Each region also has a regional office. Each regional office is headed by a director, who is elected by the Regional Committee. The board must approve such appointments, although as of 2004, it had never over-ruled the preference of a regional committee. The exact role of the board in the process has been a subject of debate, but the practical effect has always been small. Since 1999, regional directors serve for a once-renewable five-year term, and typically take their position on 1 February. Each regional committee of the WHO consists of all the Health Department heads, in all the governments of the countries that constitute the Region. Aside from electing the regional director, the regional committee is also in charge of setting the guidelines for the implementation, within the region, of the health and other policies adopted by the World Health Assembly. The regional committee also serves as a progress review board for the actions of WHO within the Region. The regional director is effectively the head of WHO for his or her region. The RD manages and/or supervises a staff of health and other experts at
