women's movement

Diverse social movement, largely based in the U.S., seeking equal rights and opportunities for women in their economic activities, personal lives, and politics. It is recognized as the “second wave” of the larger feminist movement. While first-wave feminism of the 19th and early 20th centuries focused on women's legal rights, such as the right to vote, the second-wave feminism of the “women's movement” peaked in the 1960s and '70s and touched on every area of women's experience—including family, sexuality, and work. A variety of U.S. women's groups, including the National Organization for Women, sought to overturn laws that enforced discrimination in matters such as contract and property rights and employment and pay. The movement also sought to broaden women's self-awareness and challenge traditional stereotypes of women as passive, dependent, or irrational. An effort in the 1970s to pass the Equal Rights Amendment failed, but its aims had been largely achieved by other means by the end of the 20th century.

International social movement dedicated to the control of alcohol consumption through the promotion of moderation and abstinence. It began as a church-sponsored movement in the U.S. in the early 19th century. It attracted the efforts of many women, and by 1833 there were 6,000 local temperance societies in the U.S. The first European temperance society was formed in Ireland in 1826. An international temperance movement began in Utica, N.Y., U.S., in 1851 and spread to Australia, Asia, Europe, India, South and West Africa, and South America. Seealso Carry Nation; Prohibition; Woman's Christian Temperance Movement.

In international politics, the group of states sharing the peacetime policy of avoiding political or economic affiliations with major power blocs. At its beginning the nonaligned movement consisted primarily of Asian and African states that were once colonies of the Western powers and were wary of being drawn into a new form of dependence by the West or by the communist bloc. Founded by Jawaharlal Nehru, Gamal Abdel Nasser, and others, the movement held its first official meeting in 1961 in Bandung, Indon.; 25 countries attended. Meetings have since been held on a three-year schedule. While the Soviet Union existed, the movement tended to seek development assistance from both the U.S. and the Soviet Union but to refrain from forming political or military alliances with either country. Since the dissolution of the Soviet Union in 1991, the nonaligned movement has been chiefly concerned with debt forgiveness and with development of fairer trade relationships with the West. By the early 21st century the movement had more than 110 members.

Motion of a particle moving at a constant speed on a circle. Though the magnitude of the velocity of such an object may be constant, the object is constantly accelerating because its direction is constantly changing. At any given instant its direction is perpendicular to a radius of the circle drawn to the point of location of the object on the circle. The acceleration is strictly a change in direction and is a result of a force directed toward the centre of the circle. This centripetal force causes centripetal acceleration.

Analysis of the time spent in going through the different motions of a job or series of jobs in the evaluation of industrial performance. Such studies were first instituted in offices and factories in the U.S. in the early 20th century. They were widely adopted as a means of improving work methods by subdividing the different operations of a job into measurable elements, and they were in turn used as aids in standardization of work and in checking the efficiency of workers and equipment.

Repetitive back-and-forth movement through a central, or equilibrium, position in which the maximum displacement on one side is equal to the maximum displacement on the other. Each complete vibration takes the same time, the period; the reciprocal of the period is the frequency of vibration. The force that causes the motion is always directed toward the equilibrium position and is directly proportional to the distance from it. A pendulum displays simple harmonic motion; other examples include the electrons in a wire carrying alternating current and the vibrating particles of a medium carrying sound waves.

In astronomy, the actual or apparent motion of a body in a direction opposite to that of the predominant (direct or prograde) motions of similar bodies. Observationally and historically, retrograde motion refers to the apparent reversal of the planets' motion through the stars for several months in each synodic period. This required a complex explanation in Earth-centred models of the universe (see Ptolemy) but was naturally explained in heliocentric models (see Copernican system) by the apparent motion as Earth passed by a planet in its orbit. It is now known that nearly all bodies in the solar system revolve and rotate in the same counterclockwise direction as viewed from a position in space above Earth's North Pole. This common direction probably arose during the formation of the solar nebula. The relatively few objects with clockwise motions (e.g., the rotation of Venus, Uranus, and Pluto) are also described as retrograde.

Apparent motion of a star across the celestial sphere at right angles to the observer's line of sight, generally measured in seconds of arc per year. Any radial motion (toward or away from the observer) is not included. Edmond Halley was the first to detect proper motions; the largest known is that of Barnard's star, about 10 seconds yearly.

Mathematical formula that describes the motion of a body relative to a given frame of reference, in terms of the position, velocity, or acceleration of the body. In classical mechanics, the basic equation of motion is Newton's second law (see Newton's laws of motion), which relates the force on a body to its mass and acceleration. When the force is described in terms of the time interval over which it is applied, the velocity and position of the body can be derived. Other equations of motion include the position-time equation, the velocity-time equation, and the acceleration-time equation of a moving body.

Sickness caused by contradiction between external data from the eyes and internal cues from the balance centre in the inner ear. For example, in seasickness the inner ear senses the ship's motion, but the eyes see the still cabin. This stimulates stress hormones and accelerates stomach muscle contraction, leading to dizziness, pallor, cold sweat, and nausea and vomiting. Minimizing changes of speed and direction may help, as may reclining, not turning the head, closing the eyes, or focusing on distant objects. Drugs can prevent or relieve motion sickness but may have side effects. Pressing an acupuncture point on the wrist helps some people.

or movie

Series of still photographs on film, projected in rapid succession onto a screen. Motion pictures are filmed with a movie camera, which makes rapid exposures of people or objects in motion, and shown with a movie projector, which reproduces sound synchronized with the images. The principal inventors of motion-picture machines were Thomas Alva Edison in the U.S. and the Lumière brothers in France. Film production was centred in France in the early 20th century, but by 1920 the U.S. had become dominant. As directors and stars moved to Hollywood, movie studios expanded, reaching their zenith in the 1930s and '40s, when they also typically owned extensive theatre chains. Moviemaking was marked by a new internationalism in the 1950s and '60s, which also saw the rise of the independent filmmaker. The sophistication of special effects increased greatly from the 1970s. The U.S. film industry, with its immense technical resources, has continued to dominate the world market to the present day. Seealso Columbia Pictures; MGM; Paramount Communications; RKO; United Artists; Warner Brothers.

Change in position of a body relative to another body or with respect to a frame of reference or coordinate system. Motion occurs along a definite path, the nature of which determines the character of the motion. Translational motion occurs if all points in a body have similar paths relative to another body. Rotational motion occurs when any line on a body changes its orientation relative to a line on another body. Motion relative to a moving body, such as motion on a moving train, is called relative motion. Indeed, all motions are relative, but motions relative to the Earth or to any body fixed to the Earth are often assumed to be absolute, as the effects of the Earth's motion are usually negligible. Seealso Brownian motion; periodic motion; simple harmonic motion; simple motion; uniform circular motion.

Relations between the forces acting on a body and the motion of the body, formulated by Isaac Newton. The laws describe only the motion of a body as a whole and are valid only for motions relative to a reference frame. Usually, the reference frame is the Earth. The first law, also called the law of inertia, states that if a body is at rest or moving at constant speed in a straight line, it will continue to do so unless it is acted upon by a force. The second law states that the force math.F acting on a body is equal to the mass math.m of the body times its acceleration math.a, or math.F = math.mmath.a. The third law, also called the action-reaction law, states that the actions of two bodies on each other are always equal in magnitude and opposite in direction.

Any of various physical phenomena in which some quantity is constantly undergoing small, random fluctuations. It was named for Robert Brown, who was investigating the fertilization process of flowers in 1827 when he noticed a “rapid oscillatory motion” of microscopic particles within pollen grains suspended in water. He later discovered that similar motions could be seen in smoke or dust particles suspended in air and other fluids. The idea that molecules of a fluid are constantly in motion is a key part of the kinetic theory of gases, developed by James Clerk Maxwell, Ludwig Boltzmann, and Rudolf Clausius (1822–88) to explain heat phenomena.

Bulk movements of soil and rock debris down slopes, or the sinking of confined areas of the Earth's ground surface. The term mass wasting refers only to gravity-driven processes that move large masses of earthen material from one place to another. The term mass movement includes the sinking of confined areas.

Form of adult education popular in the U.S. during the mid-19th century. The lyceums were voluntary local associations that sponsored lectures and debates on topics of current interest. The first was founded in 1826, and by 1834 there were approximately 3,000 in the Northeast and Midwest. They attracted such speakers as Ralph Waldo Emerson, Frederick Douglass, Henry David Thoreau, Daniel Webster, Nathaniel Hawthorne, and Susan B. Anthony. The movement began to decline with the outbreak of the Civil War and eventually blended into the postbellum Chautauqua movement. In their heyday the lyceums contributed to the broadening of the school curricula and the development of local museums and libraries.

or homosexual rights movement

Civil-rights movement that advocates equal rights for gay men, lesbians, bisexuals, and transsexuals. Supporters of gay rights seek to eliminate sodomy laws barring homosexual acts between consenting adults and call for an end to discrimination against gay men and lesbians in employment, credit, lending, housing, marriage, adoption, public accommodations, and other areas of life. The first group to campaign publicly was founded in Berlin in 1897 by Magnus Hirschfeld (1868–1935) and had 25 local chapters in Europe by 1922; suppressed by the Nazis, it did not survive World War II. The first U.S. support group, the Mattachine Society, was founded in Los Angeles circa 1950; the Daughters of Bilitis, for lesbians, was founded in San Francisco in 1955. The Dutch Association for the Integration of Homosexuality COC, founded as the COC (Cultuur en Ontspannings Centrum [“Culture and Recreation Center”]) in 1946 and headquartered in Amsterdam, is a prominent European group and the oldest existing gay rights organization. Many date the expansion of the modern gay rights movement to the Stonewall rebellion in New York City in 1969, when a raid by police on a gay bar called the Stonewall Inn provoked a riot by bar patrons. “Stonewall” came to be commemorated annually by the observance of Gay and Lesbian Pride Week in cities around the world. The International Lesbian and Gay Association (founded 1978), headquartered in Brussels, lobbies for human rights and opposes discrimination against homosexuals. Although the movement is strongest in western Europe and North America, gay rights organizations exist in many countries throughout the world. Among the major issues pressed by gay rights advocates in the 1990s and into the 21st century were the passage of hate crime laws and the establishment of legal rights for homosexuals to marry, adopt children, and serve openly in the military.

Division or consolidation of communal lands in Western Europe into the carefully delineated and individually owned farm plots of modern times. Before enclosure, farmland was under the control of individual cultivators only during the growing season; after harvest and before the next growing season, the land was used by the community for the grazing of livestock and other purposes. In England the movement for enclosure began in the 12th century and proceeded rapidly from 1450 to 1640; the process was virtually complete by the end of the 19th century. In the rest of Europe, enclosure made little progress until the 19th century. Common rights over arable land have now been largely eliminated.

Movement toward unity or cooperation among the Christian churches. The first major step in the direction of ecumenism was the International Missionary Conference of 1910, a gathering of Protestants. Several Protestant denominations inaugurated a Life and Work Conference (on social and practical problems) in 1925 and a Faith and Order Conference (on church doctrine and governance) in 1927. After World War II the World Council of Churches (WCC) was established; the International Missionary Conference joined it in 1961. The Roman Catholic church also has shown strong interest in improving interchurch relations since the Second Vatican Council (1962–65) and, with the patriarch of Constantinople, has lifted the excommunication of 1054. The Eastern Orthodox church was active in the movement since 1920 and joined the WCC at its inception. The more conservative or fundamentalist Protestant denominations have generally refrained from involvement. Another important factor in 20th-century ecumenism was the creation of united churches that reconcile splintered sects, such as the United Church of Christ (1957) and the Evangelical Lutheran Church in America (1988).

Popular U.S. educational and cultural movement founded in 1874. It began as a training assembly for Sunday-school teachers at Chautauqua Lake, N.Y., but gradually spread to various circuit “chautauquas” and broadened in scope to include general education and popular entertainments, many of which incorporated religious themes. Outstanding speakers were brought in for summer lectures and classes. The movement declined after reaching a peak in 1924 (though the Chautauqua Institution still holds meetings), but its legacy contributed to the growth of community colleges and continuing education programs. Seealso lyceum movement.

or bowel movement

Elimination of feces from the digestive tract. Peristalsis moves feces through the colon to the rectum, where they stimulate the urge to defecate. The rectum shortens, pushing the feces into the anal canal, where internal and external sphincters allow them to be passed or retained. Chest, abdominal, and pelvic muscles are used to pass them. Long delay of defecation causes constipation and hardened feces. Seealso diarrhea, incontinence.

or Black Arts movement

Period of artistic and literary development among black Americans in the 1960s and early '70s. Based on the cultural politics of black nationalism, the movement sought to create art forms capable of expressing the varieties of black experience in the U.S. Leading theorists included Amiri Baraka, Houston Baker (b. 1943), and Henry Louis Gates. Don L. Lee (b. 1942), known as Haki R. Madhubuti after 1973, was one of its most popular writers; other notable writers included Toni Morrison, Alice Walker, and Ntozake Shange (b. 1948). The movement also produced such autobiographical works as The Autobiography of Malcolm X (1965; with Alex Haley), Eldridge Cleaver's Soul on Ice (1968), and Angela Davis: An Autobiography (1974).

(circa 1783–1888) Movement to end the slave trade and emancipate slaves in western Europe and the Americas. The slave system aroused little protest until the 18th century, when rationalist thinkers of the Enlightenment criticized it for violating the rights of man, and Quaker and other evangelical religious groups condemned it as un-Christian. Though antislavery sentiments were widespread by the late 18th century, they had little immediate effect on the centres of slavery themselves—the West Indies, South America, and the southern U.S. In 1807 the importation of African slaves was banned in the U.S. and the British colonies. Slavery was abolished in the British West Indies by 1838 and in the French possessions 10 years later. In the 11 Southern states of the U.S., however, slavery was a social and economic institution. American abolitionism laboured under the handicap that it threatened the harmony of North and South in the Union, and it also ran counter to the U.S. Constitution, which left the question of slavery to the individual states. The abolitionist movement in the North was led by agitators such as William Lloyd Garrison, founder of the American Anti-Slavery Society, writers such as John Greenleaf Whittier, former slaves such as Frederick Douglass, and Harriet Beecher Stowe. The election of Abraham Lincoln, who opposed the spread of slavery to the West, marked a turning point in the movement. Convinced that their way of life was threatened, the Southern states seceded from the Union (see secession), which led to the American Civil War. In 1863 Lincoln (who had never been an abolitionist) issued the Emancipation Proclamation, which freed slaves held in the Confederate states; the 13th Amendment to the U.S. Constitution (1865) prohibited slavery throughout the country. Slavery was abolished in Latin America by 1888. In some parts of Africa and in much of the Islamic world, it persisted as a legal institution well into the 20th century.

or Tractarian movement

(1833–45) Movement within the Church of England that aimed to emphasize the church's Catholic inheritance as a source of legitimacy and deeper spirituality. Its main intent was to defend the Church of England as a divine institution against the threats of liberal theology, rationalism, and government interference. Though some in the movement (notably John Henry Newman and Henry E. Manning) ended up converting to Catholicism, most did not. Their concern for a higher standard of worship influenced not only the Church of England but also other British Protestant sects. The movement was also instrumental in the establishment of Anglican monasteries and convents.

Chinese intellectual revolution and sociopolitical reform movement (1917–21). In 1915 young intellectuals inspired by Chen Duxiu began agitating for the reform and strengthening of Chinese society through acceptance of Western science, democracy, and schools of thought, one objective being to make China strong enough to resist Western imperialism. On May 4, 1919, reformist zeal found focus in a protest by Beijing's students against the Versailles Peace Conference's decision to transfer former German concessions in China to Japan. After more than a month of demonstrations, strikes, and boycotts of Japanese goods, the government gave way and refused to sign the peace treaty with Germany. The movement spurred the successful reorganization of the Nationalist Party and gave birth to the Chinese Communist Party. Seealso Treaty of Versailles.

Coalition of U.S. farmers, mainly in the Midwest, that fought monopolistic grain-transport practices in the 1870s. Oliver H. Kelley (1826–1913), a U.S. Department of Agriculture employee, organized the Patrons of Husbandry in 1867 to bring farmers together to learn new farming methods. By the mid-1870s almost every state had at least one branch, or Grange, and national membership passed 800,000. The Grangers influenced some states to pass regulatory legislation to counter the price-fixing by railroads and grain-storage facilities. Outgrowths of the Granger movement included the Greenback and Populist movements. The Grangers dropped to about 100,000 members by 1880; they rebounded in the early 20th century, but declined again subsequently.

Irish nationalist society active chiefly in Ireland, the U.S., and Britain, especially in the 1860s. The name derived from the Fianna Éireann, a legendary band of Irish warriors led by Finn MacCumhaill. Plans for a rising against British rule in Ireland miscarried, but in the U.S., Fenians staged abortive raids into British Canada and caused friction between the U.S. and British governments. The Irish wing was sometimes called the Irish Republican Brotherhood, and as such continued after Fenianism died out in the early 1870s. Seealso Sinn Féin.

American social and literary movement of the 1950s and '60s. It is associated with artists' communities in San Francisco, Los Angeles, and New York. Its adherents expressed alienation from conventional society and advocated personal release and illumination through heightened sensory awareness and altered states of consciousness. Beat poets, including Lawrence Ferlinghetti, Allen Ginsberg, Gregory Corso (1930–2001), and Gary Snyder, sought to liberate poetry from academic refinement, creating verse that was vernacular, sometimes sprinkled with obscenities, but often powerful and moving. Jack Kerouac and William S. Burroughs developed an unstructured, spontaneous, sometimes hallucinatory approach to prose writing that was designed to convey the immediacy of experience. The Beat movement had faded by circa 1970, though its influence continued to be felt decades later.

Civil rights organization founded in 1968, originally to help urban American Indians displaced by government programs. It later broadened its efforts to include demands for economic independence, autonomy over tribal areas, restoration of illegally seized lands, and protection of Indian legal rights and traditional culture. Some of its protest activities involved violence and were highly publicized (see Wounded Knee). Internal strife and the imprisonment of some leaders led to the disbanding of its national leadership in 1978, though local groups have continued to function.
