white-ground

Examples of white-ground in the following topics:

• Ceramics in the Greek Early Classical Period

  • This depiction of Herakles fighting Geryon provides an example of Type I white-ground painting.
  • The Achilles Painter, a pupil of the Berlin Painter and creator of both red-figure and white-ground vessels, is one of the most well-known white ground painters.
  • Attic white ground lekythos. c. 440-430 BCE.
  • Attic white-ground black-figure lekythos.
  • Attic white ground lekythos. c. 440-430 BCE.

• Organization

  • A few of these laws of grouping include the laws of proximity, similarity, and closure and the figure-ground law.
  • In perceiving a visual field, some objects have a prominent role (the figures) while others recede into the background (the ground).
  • Because of the law of similarity, people tend to see this as six clusters of black and white dots rather than 36 individual dots.
  • In the Kanizsa triangle illusion, the figure-ground law causes most people to perceive a white triangle in the foreground, which makes the black shapes recede into the background.

• Safety Precautions in the Household

  • There are three connections to the earth or ground (earth/ground, ).
  • The third earth/ground connection involves the case of the appliance, through the green earth/ground wire, forcing the case to be at zero volts.
  • Grounding the case solves more than one problem, however.
  • Neutral wires may be blue, black, or white.
  • If grounded, the case voltage is kept near zero, but if the case is not grounded, a shock can occur.

• Progressivism for Whites Only

  • Another progressive president, Woodrow Wilson, has been criticized by several historians on racial grounds.
  • According to critics, Wilson believed that slavery was wrong on economic labor grounds, rather than for moral reasons.
  • Typically the progressive elements in the states pushed for disenfranchisement, often fighting against the conservatism of the Black Belt whites.
  • A major reason given was that whites routinely purchased black votes to control elections, and it was easier to disenfranchise blacks than to go after powerful white men.
  • The AFL also initiated one of the first organized labor boycotts against Chinese immigrant workers, by putting white stickers on the cigars made by unionized white cigar rollers while simultaneously discouraging consumers from purchasing cigars rolled by Chinese workers.

• The Bourbons and the Redeemers

  • The Thirteenth Amendment (banning slavery), Fourteenth Amendment (guaranteeing the civil rights of former slaves and ensuring equal protection of the laws), and Fifteenth Amendment (prohibiting the denial of the right to vote on grounds of race, color, or previous condition of servitude) enshrined such political rights in the Constitution.
  • In the 1870s, white Democratic Southerners saw themselves redeeming the South by regaining power.
  • In 1868, white terrorists tried to prevent Republicans from winning the fall election in Louisiana.
  • They also worked to reestablish white supremacy.
  • George Henry White, the last Southern black of the post-Reconstruction period to serve in Congress, retired in 1901, leaving Congress completely white.

• Photocopy Machines and Printers

  • The conductor is put on top of a conducting surface and is kept at ground potential.
  • A positive process is used to produce black on white copies, while a negative process is used to produce black on white from negative originals.
  • The white areas of the original reflect light onto the surface of the drum, which exhibits photoconductivity (it becomes a conductor in the presence of light).
  • The areas of the drum exposed to light then discharge to the ground; the other parts of the drum (which are not conductive, having not been exposed to light) remain negatively charged.

• Temperate Forests

  • The trees of the temperate forests leaf out and shade much of the ground; however, this biome is more open than tropical wet forests because trees in the temperate forests do not grow as tall as the trees in tropical wet forests.
  • The leaf litter also protects soil from erosion, insulates the ground, and provides habitats for invertebrates (such as the pill bug or roly-poly, Armadillidium vulgare) and their predators, such as the red-backed salamander (Plethodon cinereus).
  • Deer such as the white-tailed deer of North America are common inhabitants of temperate forests.

• The Cover-Up and the Unraveling

  • In May, former deputy White House counsel John Dean, a source close to Nixon, would testify that there indeed had been a cover-up and that it had been directed by Nixon himself.
  • In July, White House aide Alexander Butterfield testified that Nixon had a secret taping system that recorded his conversations and phone calls in the Oval Office.
  • Nixon refused on grounds of executive privilege, contending that the release of the tapes would compromise national security.
  • In November, Nixon's lawyers revealed that an audio tape of conversations held in the White House on June 20, 1972, featured an 18½ minute gap.
  • He tried to prevent a special prosecutor from obtaining recordings of White House phone calls.

• Change in the Democratic Party

  • The racial tension within the Republican Party was exacerbated because poor whites resented the job competition from freedmen.
  • They decided it would be more successful to fight the Republican Party on economic grounds rather than race.
  • They also worked to reestablish white supremacy.
  • As Democrats took over state legislatures, they worked to change voter registration rules to strip most blacks and many poor whites of their ability to vote.
  • George Henry White, the last Southern black of the post-Reconstruction period to serve in Congress, retired in 1901, leaving Congress completely white.

• The Radical Record

  • As the chief Radical leader in the Senate during Reconstruction, Sumner fought hard to provide equal civil and voting rights for the freedmen on the grounds that "consent of the governed" was a basic principle of American republicanism, and to block ex-Confederates from power so they would not reverse the gains made from the Union's victory in the Civil War.
  • The Democratic Party, proclaiming itself the party of white men, north and south, supported Johnson.
  • While many blacks took an active part in voting and political life, and rapidly continued to build churches and community organizations, white Democrats and insurgent groups used force to regain power in the state legislatures, passing laws that effectively disfranchised most blacks and many poor whites in the South.
  • This was followed by a period that white Southerners labeled Redemption, during which white-dominated state legislatures enacted Jim Crow laws and, beginning in 1890, disenfranchised most blacks and many poor whites through a combination of constitutional amendments and electoral laws.
  • The white Democrat Southerners' memory of Reconstruction played a major role in imposing the system of white supremacy and second-class citizenship for blacks, known as the age of Jim Crow.
