Government

A government is the system by which a state or community is controlled. In the Commonwealth of Nations, the word government is also used more narrowly to refer to the collective group of people that exercises executive authority in a state. This usage is analogous to what is called an "administration" in American English. Furthermore, especially in American English, the concepts of the state and the government may be used synonymously to refer to the person or group of people exercising authority over a politically organized territory. Finally, government is also sometimes used in English as a synonym for governance.

In the case of its broad associative definition, government normally consists of legislators, administrators, and arbitrators. Government is the means by which state policy is enforced, as well as the mechanism for determining the policy of the state. A form of government, or form of state governance, refers to the set of political systems and institutions that make up the organisation of a specific government.

Executive (government)

The executive is the organ that exercises authority in and holds responsibility for the governance of a state. The executive executes and enforces law.

In political systems based on the principle of separation of powers, authority is distributed among several branches (executive, legislative, judicial) — an attempt to prevent the concentration of power in the hands of a small group of people. In such a system, the executive does not pass laws (the role of the legislature) or interpret them (the role of the judiciary). Instead, the executive enforces the law as written by the legislature and interpreted by the judiciary. The executive can be the source of certain types of law, such as a decree or executive order. Executive bureaucracies are commonly the source of regulations.

In the Westminster political system, the principle of separation of powers in not as entrenched. Members of the executive, called ministers, are also members of the legislature, and hence play an important part in both the writing and enforcing of law.

Government of Ireland

The Government of Ireland (Irish: Rialtas na hÉireann) is the cabinet that exercises executive authority in Ireland.

Members of the government

The structure of the Government of Ireland is regulated fundamentally by the Constitution of Ireland. The Government is headed by a prime minister called the Taoiseach. The deputy prime minister is called the Tánaiste, and is nominated by the Taoiseach from among the members of the Government.

The Government must consist of between seven and fifteen members, according to the Constitution of Ireland. Every member of the Government must be a member of the parliament of Ireland, called the Oireachtas. No more than two members of the Government may be members of Seanad Éireann, the upper house of the Oireachtas. Therefore, all other members of the Government must be members of Dáil Éireann, the lower house. The Taoiseach, Tánaiste and Minister for Finance must be members of the Dáil.

The Taoiseach is nominated by Dáil Éireann, the lower house of the Oireachtas, and appointed by the President. Other members of the Government are nominated by the Taoiseach, approved by Dáil Éireann, and appointed by the President. Members of the government are often styled "cabinet ministers", as opposed to Ministers of State (before 1977 Parliamentary Secretaries), called "junior ministers", who are not in the cabinet. A minister is usually in charge of a Department of State and thus technically a "Minister of the Government" (before 1977 a "Minister of State"). Occasionally a minister without portfolio is appointed who is a minister and a member of the Government but not a "Minister of the Government".

Book

A book is a set of written, printed, illustrated, or blank sheets, made of ink, paper, parchment, or other materials, fastened together to hinge at one side. A single sheet within a book is a leaf, and each side of a leaf is a page. A set of text-filled or illustrated pages produced in electronic format is known as an electronic book, or e-book.

Books may also refer to works of literature, or a main division of such a work. In library and information science, a book is called a monograph, to distinguish it from serial periodicals such as magazines, journals or newspapers. The body of all written works including books is literature. In novels and sometimes other types of books (for example, biographies), a book may be divided into several large sections, also called books (Book 1, Book 2, Book 3, and so on). An avid reader of books is a bibliophile or colloquially, bookworm.

A shop where books are bought and sold is a bookshop or bookstore. Books can also be borrowed from libraries. Google has estimated that as of 2010, approximately 130,000,000 unique titles had been published. In some wealthier nations, printed books are giving way to the usage of electronic or e-books, though sales of e-books declined in the first half of 2015.

Book (graph theory)

In graph theory, a book graph (often written  ) may be any of several kinds of graph.

One kind, which may be called a quadrilateral book, consists of p quadrilaterals sharing a common edge (known as the "spine" or "base" of the book). A book of this type is the Cartesian product of a star and K₂ .

A second type, which might be called a triangular book, is the complete tripartite graph K_1,1,p. It is a graph consisting of triangles sharing a common edge. A book of this type is a split graph. This graph has also been called a .

Given a graph , one may write for the largest book (of the kind being considered) contained within .

The term "book-graph" has been employed for other uses. Barioli used it to mean a graph composed of a number of arbitrary subgraphs having two vertices in common. (Barioli did not write for his book-graph.)

Musical theatre

Musical theatre is a form of theatrical performance that combines songs, spoken dialogue, acting, and dance. The story and emotional content of a musical – humor, pathos, love, anger – are communicated through the words, music, movement and technical aspects of the entertainment as an integrated whole. Although musical theatre overlaps with other theatrical forms like opera and dance, it may be distinguished by the equal importance given to the music as compared with the dialogue, movement and other elements. Since the early 20th century, musical theatre stage works have generally been called, simply, musicals.

Although music has been a part of dramatic presentations since ancient times, modern Western musical theatre emerged during the 19th century, with many structural elements established by the works of Gilbert and Sullivan in Britain and those of Harrigan and Hart in America. These were followed by the numerous Edwardian musical comedies and the musical theatre works of American creators like George M. Cohan. The Princess Theatre musicals and other smart shows like Of Thee I Sing (1931) were artistic steps forward beyond revues and other frothy entertainments of the early 20th century and led to such groundbreaking works as Show Boat (1927) and Oklahoma! (1943). Some of the most famous and iconic musicals through the decades that followed include West Side Story (1957), The Fantasticks (1960), Hair (1967), A Chorus Line (1975), Les Misérables (1985), The Phantom of the Opera (1986), Rent (1996), The Producers (2001) and Wicked (2003).
