- National Association for the Advancement of Colored People (NAACP), organization composed mainly of American blacks, but with many white members, whose goal is the end of racial discrimination and segregation. The association was formed as the direct result of the lynching (1908) of two blacks in Springfield, Ill. The incident produced a wide response by white Northerners to a call by Mary W. Ovington, a white woman, for a conference to discuss ways of achieving political and social equality for blacks. This conference led to the formation (1910) of the NAACP, headed by eight prominent Americans, seven white and one, William E. B. Du Bois , black. The selection of Du Bois was significant, for he was a black who had rejected the policy of gradualism advocated by Booker T. Washington and demanded immediate equality for blacks. From 1910 to 1934 Du Bois was the editor of the association s periodical The Crisis, which reported on race relations around the world. The new organization grew so rapidly that by 1915 it was able to organize a partially successful boycott of the motion picture The Birth of a Nation, which portrayed blacks of the Reconstruction era in a distorted light. Most of the NAACP s early efforts were directed against lynching . In this area it could claim considerable success. In 1911 there were 71 lynchings in the United States, with a black person the victim 63 times; by the 1950s lynching had virtually disappeared. Since its beginning, and with increasing emphasis since World War II, the NAACP has advocated nonviolent protests against discrimination and has disapproved of extremist black groups such as SNCC and the Black Panthers in the 1960s and 70s and CORE and the Nation of Islam in the 1980s and 90s, many of which criticized the organization as passive. While complacent in the 1980s, it became more active in legislative redistricting, voter registration, and lobbying in the 1990s. Well-known leaders of the NAACP include Moorfield Storey (1910-29), Walter White (1931-55), Roy Wilkins (1955-77), and Benjamin Hooks (1977-93). In the mid-1990s the group faced financial difficulties and a loss of confidence in its leadership, as the organization s executive director, Benjamin Chavis (see Muhammad, B. F. ), and board chairman, William Gibson, were dismissed in 1994 and 1995, respectively. Merlie Evers-Williams, widow of slain civil-rights leader Medgar Evers, replaced Gibson in 1995, and Representative Kweisi Mfume of Maryland, head of the Congressional Black Caucus, was chosen to replace Chavis in 1996, with the new title of president and chief executive officer. Mfume retired as president in 2004 and was succeeded by Bruce S. Gordon , a former telecommunications executive, who served from 2005 to 2007. Julian Bond has been board chairman since 1998. With a 2005 membership of about 500,000 in 2,200 adult branches and 1,700 youth and college chapters, the association remains the largest and most influential civil-rights organization in the United States. The NAACP Legal Defense and Education Fund, an independent legal aid group, argues in court on behalf of the NAACP and other civil-rights groups. Along with the NAACP, it was instrumental in helping to bring about the Supreme Court s ruling (1954) against segregated public education in the landmark Brown v. Board of Education of Topeka, Kans. case. Bibliography: See R. L. Jack, A History of the National Association for the Advancement of Colored People (1943); L. Hughes, Fight for Freedom (1962); B. J.

- contact receptor n. A sensory receptor such as a touch receptor or a taste receptor that is stimulated by an object or substance touching it. Compare distance receptor.
- contact lens n. a thin plastic lens placed directly on the surface of the eye to correct visual defects.
- contact sport n. a sport in which the participants necessarily come into bodily contact with one another.
- contact inhibition The cessation in vitro of both movement and replication in a cell on making contact with other cells, such that a confluent monolayer is formed in the culture. Probably it occurs as a result of the formation of cytoplasmic bridges between cells. In many cancer cells this inhibition is absent.
- eye contact n. The event of two people simultaneously gazing at each other in the vicinity of each other s eyes. Also called mutual gaze. See also equilibrium hypothesis, gaze aversion, non-verbal communication, regulator.
- contact verb contact the head officesynonyms: get/be in touch with, get hold/ahold of, communicate with, be in communication with; write to, write, notify, phone, call, speak to, reach.
- contact hypothesis n. The proposition that sheer social contact between hostile groups is sufficient to reduce intergroup hostility. Empirical evidence suggests that this is so only in certain circumstances.

- telephoto lens Camera lens with a long focal length. A true telephoto lens has a focal length longer than the physical length of the lens, as opposed to a long-focus lens, in which the focal length is equal to the physical length. For a 35mm camera, any lens with a focal length of more than c.80mm may be regarded as a telephoto lens. For larger-format cameras, the focal length may be as much as 1000mm.See also photography
- crystalline lens n. The biconvex, transparent, elastic structure immediately behind the iris of the vertebrate eye that helps to focus light rays on to the retina, although most (about two-thirds) of the refraction of light entering the eye occurs at the cornea. The degree of convexity of the crystalline lens can be altered by radial ciliary muscles up to about age 45, after which the lens becomes hard and its focus cannot be altered. See also aberration (3), accommodation (1), ametropia, aphakia, astigmatism, cataract, cycloplegia, lens, refraction. Compare compound eye, ommatidium.[So called because of its internal crystalline structure]
- lens XVII. L. lens LENTIL; so called on account of its shape.
- Series of concentric rings, each consisting of a thin part of a simple lens, assembled on a flat surface. G.-L.-L. Buffon (1748) first had the idea of dividing a lens surface into concentric rings to reduce the weight. In 1820 his idea was adopted by Augustin-Jean Fresnel (1788 1827) for the construction of lighthouse lenses. Fresnel lenses have the optical properties of much thicker and heavier lenses. They are used in spotlights, floodlights, railroad and traffic signals, and decorative lights. Some thin Fresnel lenses are molded in plastic, the width of the rings being only a few thousandths of an inch; such lenses are used in cameras and small projectors.
- contact lens Lens worn on the cornea to aid defective vision. Invented in 1887, lenses were initially made of glass. Modern contact lenses, developed (1948) by Kevin Tuohy, are made of plastic. Hard (corneal) lenses cover the pupil and part of the cornea. They are usually gas-permeable (allowing oxygen to reach the cornea). Soft (hydrophilic) lenses cover the whole cornea and are hydrated in saline solution.
