Background Actor
A background actor or extra is a performer in a film, television show, stage, musical, opera, or ballet production who appears in a nonspeaking or nonsinging (silent) capacity, usually in the background (for example, in an audience or busy street scene). War films and epic films often employ background actors in large numbers: some films have featured hundreds or even thousands of paid background actors as cast members (hence the term "cast of thousands"). Likewise, grand opera can involve many background actors appearing in spectacular productions. On a film or TV set, background actors are usually referred to as "junior artists", "atmosphere", "background talent", "background performers", "background artists", "background cast members", or simply "background", while the term "extra" is rarely used. In a stage production, background actors are commonly referred to as "Supernumerary actor, supernumeraries". In opera and ballet, they are called either "extras" or "supers". Casting ...

Backgrounding
Backgrounding is an intermediate stage sometimes used in cattle production which begins after weaning and ends upon placement in a feedlot. Background feeding relies more heavily on forage (e.g., pasture, hay) in combination with grains to increase a calf Calf most often refers to: * Calf (animal), the young of domestic cattle. * Calf (leg), in humans (and other primates), the back portion of the lower leg Calf or calves may also refer to: Biology and animal byproducts *Veal, meat from calves *C ...'s weight by several hundred pounds and to build up immunity to diseases before it enters a feedlot. Some cattle operations specialize in backgrounding.

Provenance
Provenance (from the French ''provenir'', 'to come from/forth') is the chronology of the ownership, custody or location of a historical object. The term was originally mostly used in relation to works of art but is now used in similar senses in a wide range of fields, including archaeology, paleontology, archives, manuscripts, printed books, the circular economy, and science and computing. The primary purpose of tracing the provenance of an object or entity is normally to provide contextual and circumstantial evidence for its original production or discovery, by establishing, as far as practicable, its later history, especially the sequences of its formal ownership, custody and places of storage. The practice has a particular value in helping authenticate objects. Comparative techniques, expert opinions and the results of scientific tests may also be used to these ends, but establishing provenance is essentially a matter of documentation. The term dates to the 1780s in Englis ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Natural Heritage
Natural heritage refers to the sum total of the elements of biodiversity, including flora and fauna, ecosystems and geological structures. It forms part of our natural resources. Definition Heritage is that which is ''inherited'' from past generations, maintained in the present, and bestowed to future generations. The term "natural heritage", derived from "natural inheritance", pre-dates the term "biodiversity". It is a less scientific term and more easily comprehended in some ways by the wider audience interested in conservation. The term was used in this context in the United States when Jimmy Carter set up the Georgia Heritage Trust while he was governor of Georgia; Carter's trust dealt with both natural and cultural heritage. It would appear that Carter picked the term up from Lyndon Johnson, who used it in a 1966 Message to Congress. (He may have gotten the term from his wife Lady Bird Johnson who was personally interested in conservation.) President Johnson signed t ...

Field (heraldry)
In heraldry, the background of the shield is called the '' field''. The field is usually composed of one or more tinctures (colours or metals) or furs. The field may be divided or may consist of a variegated pattern. In rare modern cases, the field or a subdivision thereof is not a tincture but is shown as a scene from a landscape, or, in the case of the 329th Fighter Group of the United States Air Force, blazoned as ''the sky proper''.''Air Force Combat Units of World War II'', p.210 Landscape fields are regarded by many heralds as unheraldic and debased, as they defy the heraldic ideal of simple, boldly-coloured images, and they cannot be consistently drawn from blazon. The arms of the Inveraray and District Community Council in Scotland have as a field ''In waves of the sea''. The correct language of heraldry is very flexible and virtually any image may be blazoned in a correct manner, for example "sky proper" might be blazoned simply ''Azure'' or ''bleu celeste B ...

Ethnic Background
An ethnic group or an ethnicity is a grouping of people who identify with each other on the basis of shared attributes that distinguish them from other groups. Those attributes can include common sets of traditions, ancestry, language, history, society, culture, nation, religion, or social treatment within their residing area. The term ethnicity is often times used interchangeably with the term nation, particularly in cases of ethnic nationalism, and is separate from the related concept of races. Ethnicity may be construed as an inherited or as a societally imposed construct. Ethnic membership tends to be defined by a shared cultural heritage, ancestry, origin myth, history, homeland, language, or dialect, symbolic systems such as religion, mythology and ritual, cuisine, dressing style, art, or physical appearance. Ethnic groups may share a narrow or broad spectrum of genetic ancestry, depending on group identification, with many groups having mixed genetic ancestry. Ethnic ...

Cultural Heritage
Cultural heritage is the heritage of tangible and intangible heritage assets of a group or society that is inherited from past generations. Not all heritages of past generations are "heritage"; rather, heritage is a product of selection by society. Cultural heritage includes tangible culture (such as buildings, monuments, landscapes, books, works of art, and artifacts), intangible culture (such as folklore, traditions, language, and knowledge), and natural heritage (including culturally significant landscapes, and biodiversity).Ann Marie Sullivan, Cultural Heritage & New Media: A Future for the Past, 15 J. MARSHALL REV. INTELL. PROP. L. 604 (2016) https://repository.jmls.edu/cgi/viewcontent.cgi?article=1392&context=ripl The term is often used in connection with issues relating to the protection of Indigenous intellectual property. The deliberate act of keeping cultural heritage from the present for the future is known as preservation (American English) or conservation (Bri ...

Background (journalism)
In journalism, a source is a person, publication, or knowledge other record or document that gives timely information. Outside journalism, sources are sometimes known as "news sources". Examples of sources include but are not limited to official records, publications or broadcasts, officials in government or business, organizations or corporations, witnesses of crime, accidents or other events, and people involved with or affected by a news event or issue. According to Shoemaker (1996) and McQuail (1994), there are a multitude of factors that tend to condition the acceptance of sources as bona fide by investigative journalists. Reporters are expected to develop and cultivate sources, especially if they regularly cover a specific topic, known as a " beat". Beat reporters must, however, be cautious of becoming too close to their sources. Reporters often, but not always, give greater leeway to sources with little experience. For example, sometimes a person will say they don't want ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Computer Wallpaper
A wallpaper or background (also known as a desktop background, desktop picture or desktop image on computers) is a digital image (photo, drawing etc.) used as a decorative background of a graphical user interface on the screen of a computer, smartphone or other electronic device. On a computer, wallpapers are generally used on the desktop, while on a mobile phone they serve as the background for the ''home screen''. Though most devices come with a default background image, modern devices usually allow users to manually change the background image. The term "wallpaper" was used in Microsoft Windows before Windows XP (where it is called the "desktop background"), while macOS refers to it as "desktop picture". On older systems which allowed small repeated patterns to be set as background images, the term desktop pattern was used. History The X Window System was one of the earliest systems to include support for an arbitrary image as wallpaper via the xsetroot program, which at lea ...

String Background
In theoretical physics, a string background refers to the set of classical values of quantum fields in spacetime that correspond to classical solutions of string theory. Such a background is associated with geometry that solves Einstein's field equations (with higher order corrections) or their generalizations and with the values of other fields. These fields may encode the information about the shape of the hidden dimensions; the size of various electromagnetic fields and their generalizations; the values of fluxes; and the presence of additional objects such as D-branes and orientifold planes. The full physics of string theory can always be thought of as a system of infinitely many quantum fields expanded around a given string background. See also *Background independence Background independence is a condition in theoretical physics that requires the defining equations of a theory to be independent of the actual shape of the spacetime and the value of various fields within the spa ...
