Chairman

The chairman or chairwoman, or simply the chair, sometimes known as chairperson, is the highest officer of an organized group such as a board, a committee, or a deliberative assembly. The person holding the office is typically elected or appointed by the members of the group. The chair presides over meetings of the assembled group and conducts its business in an orderly fashion. When the group is not in session, the officer's duties often include acting as its head, its representative to the outside world and its spokesperson. In some organizations, this position is also called president (or other title), in others, where a board appoints a president (or other title), the two different terms are used for distinctly different positions.

Terminology

Other terms sometimes used for the office and its holder include chair, chairperson, chairwoman, presiding officer, president, moderator, facilitator, and convenor. The chairman of a parliamentary chamber is often called the speaker.

The term chair is sometimes used in lieu of chairman, in response to criticisms that using chairman is sexist. It is commonly used today, and has been used as a substitute for chairman since the middle of the 17th century, with its earliest citation in the Oxford English Dictionary dated 1658-9, only four years after the first citation for chairman.

Rail fastening system

A rail fastening system is a means of fixing rails to railroad ties (United States) or sleepers (international). The terms rail anchors, tie plates, chairs and track fasteners are used to refer to parts or all of a rail fastening system. Various types of fastening have been used over the years.

History and overview

The earliest wooden rails were fixed to wooden sleepers by pegs through holes in the rail, or by nails. By the 18th century cast iron rails had come into use, and also had holes in the rail itself to allow them to be fixed to a support. 18th century developments such as the flanged rail and fish bellied rail also had holes in the rail itself; when stone block sleepers were used the nails were driven into a wooden block which had been inserted into a recess in the block. The first chair for a rail is thought to have been introduced in 1797 which attached to the rail on the vertical web via bolts.

By the 1820s the first shaped rolled rails had begun to be produced initially of a T shape which required a chair to hold them; the rails were held in position by iron wedges (which sometimes caused the rail to break when forced in) and later by wooden wedges, which became the standard. In the 1830s Robert L. Stevens invented the flanged 'tee' rail (actually a distorted I beam), which had a flat bottom and required no chair; a similar design was the contemporary bridge rail (of inverted U section with a bottom flange and laid on longitudinal sleepers); these rails were initially nailed directly to the sleeper.

Chair (sculpture)

Chair is a public artwork designed as an advertisement by Bassett Furniture, located at the intersection of Martin Luther King Ave. and V. Street S.E., in the Anacostia neighborhood of Washington, D.C., United States of America. Chair was originally surveyed as part of the Smithsonian's Save Outdoor Sculpture! survey in 1994. It was once considered the world's largest chair, but has been overtaken by works like Broken Chair in Geneva and the temporary The Writer on Hampstead Heath in London.

Description

The chair, which stands 19 1/2 feet high, is a detail-to-detail replica of a Duncan Phyfe style chair. Painted brown with a white and brown striped "cushion", the chair is entirely made of aluminum. Weighing between 4,000 and 4,600 pounds, the chair sits on a concrete base.

Acquisition

The chair was built in 1959 by Virginia-based furniture maker Bassett Furniture. The concept for the chair came from Charles Curtis, of the Curtis Brothers Furniture company, as a clever way to bring customers to their family showroom which was located on the grounds where the chair is currently placed.

Holy Roman Emperor

The Holy Roman Emperor (German: Römisch-deutscher Kaiser, Latin: Romanorum Imperator) was the ruler of the Holy Roman Empire. From an autocracy in Carolingian times the title evolved into an elected monarchy chosen by the Prince-electors. Until the Reformation the Emperor elect (imperator electus) was required to be crowned by the Pope before assuming the imperial title.

The title was held in conjunction with the rule of the Kingdom of Germany and the Kingdom of Italy (Imperial Northern Italy). In theory, the Holy Roman Emperor was primus inter pares (first among equals) among the other Roman Catholic monarchs; in practice, a Holy Roman Emperor was only as strong as his army and alliances made him.

Various royal houses of Europe, at different times, effectively became hereditary holders of the title, in particular in later times the Habsburgs. After the Reformation many of the subject states and most of those in Germany were Protestant while the Emperor continued to be Catholic. The Holy Roman Empire was dissolved by the last Emperor (who became simply the Emperor of Austria) as a result of the collapse of the polity during the Napoleonic wars.

Emperor of China

The Emperor of China (Chinese: 皇帝; pinyin:  Huángdì) was the title of any sovereign of Imperial China reigning between the founding of the Qin dynasty that unified China in 221 BC, until the abdication of Puyi in 1912 following the Xinhai Revolution and the establishment of the Republic of China. The emperor was also referred to as the "Son of Heaven" (Chinese: 天子; pinyin: tiānzǐ), a title that predates the Qin unification, and recognized as the ruler of "all under heaven" (i.e., the whole world). In practice not every Emperor held supreme power in China, although this was usually the case.

Emperors from the same family are classified in historical periods known as dynasties. Most of China's imperial rulers have commonly been considered members of the Han ethnicity, although recent scholarship tends to be wary of applying present day ethnic categories to historical situations. During the Yuan and Qing dynasties China was ruled by ethnic Mongols and Manchus respectively. The orthodox historical view sees these as non-native dynasties that became sinicized, though some recent scholars (such as those of the New Qing History school) argue that the interaction between politics and ethnicity was far more complex. Nevertheless, in both cases these rulers claimed the Mandate of Heaven to assume the role of traditional Confucian emperors in order to rule over China proper.
