The Southern United States—commonly referred to as the American South, Dixie, or simply the South—is an area comprising the southeastern and south-central United States. The region is known for its culture and history, having developed its own customs, musical styles and varied cuisines that have helped distinguish it in some ways from the rest of the United States. The Southern ethnic heritage is diverse and includes strong European (mostly English, Scotch-Irish and Scottish), African, and some Native American components. Several Southern states (Virginia, North Carolina, South Carolina, and Georgia) were English Colonies that sent delegates to sign the Declaration of Independence and then fought against the English along with the Northern Colonists during the Revolutionary War. The basis for much Southern culture derives from the pride in these states being among the 13 original colonies (and much of the population of the South had fore-fathers who emigrated west from these colonies). Manners and customs reflect the early population of the South's relationship with England as well as that of Africa and to some extent the native populations.
Some other aspects of the historical and cultural development of the South have been influenced by an early support for the doctrine of states' rights, the institution of slave labor on plantations in the Lower South; the presence of a large proportion of African Americans in the population; and the legacy of the Civil War and Reconstruction Era, as seen in thousands of lynchings (mostly from 1880 to 1930), the segregated system of separate schools and public facilities known as "Jim Crow", that lasted until the 1960s, and the widespread use of poll taxes and other methods to frequently deny blacks of the right to vote or hold office until the 1960s. In more modern times, however, the South has become the most integrated region of the country and race-relations on par with those elsewhere. Since the late 1960s blacks have held and currently hold many high offices, such as mayor and police chief, in many cities such as Atlanta and New Orleans.
Human-based computation (HBC) is a computer science technique in which a machine performs its function by outsourcing certain steps to humans. This approach uses differences in abilities and alternative costs between humans and computer agents to achieve symbiotic human-computer interaction.
In traditional computation, a human employs a computer to solve a problem; a human provides a formalized problem description and an algorithm to a computer, and receives a solution to interpret. Human-based computation frequently reverses the roles; the computer asks a person or a large group of people to solve a problem, then collects, interprets, and integrates their solutions.
Social search or a social search engine is a type of web search that takes into account the Social Graph of the person initiating the search query. When applied to web search this Social-Graph approach to relevance is in contrast to established algorithmic or machine-based approaches where relevance is determined by analyzing the text of each document or the link structure of the documents. Search results produced by social search engine give more visibility to content created or "touched" by users in the Social Graph.
Social search takes many forms, ranging from simple shared bookmarks or tagging of content with descriptive labels to more sophisticated approaches that combine human intelligence with computer algorithms.
In family law and public policy, child support (or child maintenance) is an ongoing, periodic payment made by a parent for the financial benefit of a child following the end of a marriage or other relationship. Child maintenance is paid directly or indirectly by an obligor to an obligee for the care and support of children of a relationship that has been terminated, or in some cases never existed. Often the obligor is a non-custodial parent. The obligee is typically a custodial parent, a caregiver, a guardian, or the state.
Depending on the jurisdiction, a custodial parent may pay child support to a non-custodial parent. Typically one has the same duty to pay child support irrespective of sex, so a mother is required to pay support to a father just as a father must pay a mother. Where there is joint custody, the child is considered to have two custodial parents and no non-custodial parents, and a custodial parent with a higher income (obligor) may be required to pay the other custodial parent (obligee).
