Dualism (politics): In Dutch politics the term dualism is used to refer to the separation of powers between the cabinet and parliament.  In this respect, the way the Dutch cabinets function is somewhat semi-presidential in its system of government, not parliamentary.  Unlike the presidential system, the legislative branch consists of the cabinet together with the parliament and cabinets are formed on basis of a majority in parliament.  Unlike the Westminster parliamentary system, cabinet ministers cannot be members of parliament.  An important political issue is whether ministers and leaders of governing parliamentary parties should prepare important political decisions.  According to the dualistic position, members of parliament of governing parties should function independently of their cabinet.  The term monism is used to refer to a stance that important decisions should be prepared by the members of the governing coalition in order to promote political stability.

New Order (Indonesia): Immediately following the attempted coup in 1965, the political situation was uncertain, but the Suharto's New Order found much popular support from groups wanting a separation from Indonesia's problems since its independence.

Following Indonesia's communal and political conflicts, and its economic collapse and social breakdown of the late 1950s through to the mid-1960s, the "New Order" was committed to achieving and maintaining political order, economic development, and the removal of mass participation in the political process.  The features of the "New Order" established from the late 1960s were thus a strong political role for the military, the bureaucratisation and corporatisation of political and societal organisations, and selective but effective repression of opponents.  Strident anti-communism remained a hallmark of the regime for its subsequent 32 years.
