In 1975, there was widespread press coverage of a Labour Party report into the entryist tactics of Militant. Between 1975 and 1980, attempts by Reg Underhill and others in the leadership of the Labour Party to expel Militant were rejected by its National Executive Committee, which appointed a Militant member to the position of National Youth Organiser in 1976 after Militant had won control of the party's youth section, the Labour Party Young Socialists.
In 1982, after the Liverpool Labour Party adopted Militant's strategy to set an illegal deficit budget, a Labour Party commission found Militant in contravention of clause II, section 3 of the party's constitution which made political groups with their own "Programme, Principles and Policy for separate and distinctive propaganda" ineligible for affiliation. Militant was proscribed by the Labour Party's National Executive Committee in December 1982, and the following year five members of the Editorial Board of the Militant newspaper were expelled from the Labour Party. At this point, the group claimed to have 4,300 members. Further expulsions of Militant activists followed. Militant policies dominated Liverpool City Council between 1983 and 1987 and the council organised mass opposition to government cuts to the rate support grant. 47 councillors were banned and surcharged. The conduct of the Liverpool council led Neil Kinnock, Labour's then leader, to denounce Militant at the 1985 Party Conference. Eventually Militant's two remaining Labour MPs were prevented from being Labour candidates at the 1992 general election.
In one dimension, the square modulus of the wave function, , represents the probability density of finding the particle at position . Hence the expected value of a measurement of the position of the particle is
Accordingly, the quantum mechanical operator corresponding to position is , where
The circumflex over the x on the left side indicates an operator, so that this equation may be read The result of the operator x acting on any function ψ(x) equals x multiplied by ψ(x). Or more simply, the operator x multiplies any function ψ(x) by x.
The eigenfunctions of the position operator, represented in position space, are Dirac delta functions.
To show this, suppose that is an eigenstate of the position operator with eigenvalue . We write the eigenvalue equation in position coordinates,
The term "position" is also used in the context of finance for the amount of securities or commodities held by a person, firm, or institution, and for the ownership status of a person's or institution's investments.
Position in team sports refers to the joint arrangement of a team on its field of play during a game and to the standardized place of any individual player in that arrangement. Much instruction, strategy, and reporting is organized by a set of individual player positions that is standard for the sport.
Some player positions may be official, others unofficial. For example, baseball rules govern the pitcher by that name, but not the shortstop, where pitcher and shortstop are two of baseball's nine fielding positions.
