William Sealy Gosset

William Sealy Gosset (13 June 1876 – 16 October 1937) was an English statistician. He published under the pen name Student, and developed the Student's t-distribution.

Life and career

Born in Canterbury, England to Agnes Sealy Vidal and Colonel Frederic Gosset, Gosset attended Winchester College before reading chemistry and mathematics at New College, Oxford. Upon graduating in 1899, he joined the brewery of Arthur Guinness & Son in Dublin, Ireland.

As an employee of Guinness, a progressive agro-chemical business, Gosset applied his statistical knowledge – both in the brewery and on the farm – to the selection of the best yielding varieties of barley. Gosset acquired that knowledge by study, by trial and error, and by spending two terms in 1906–1907 in the biometrical laboratory of Karl Pearson. Gosset and Pearson had a good relationship. Pearson helped Gosset with the mathematics of his papers, including the 1908 papers, but had little appreciation of their importance. The papers addressed the brewer's concern with small samples; biometricians like Pearson, on the other hand, typically had hundreds of observations and saw no urgency in developing small-sample methods.

Christ Church, Oxford

Christ Church (Latin: Ædes Christi, the temple or house, ædēs, of Christ, and thus sometimes known as "The House") is a constituent college of the University of Oxford in England. The college is associated with Christ Church Cathedral, Oxford, which serves as the college chapel and whose dean is ex officio the college head.

Like its sister college, Trinity College, Cambridge, it was traditionally considered the most aristocratic college of its university. It is the second wealthiest Oxford college by financial endowment (after St John's) with an endowment of £371.5m as of 2014.

Christ Church has produced thirteen British prime ministers, more than any other Oxbridge college.

The college was the setting for parts of Evelyn Waugh's Brideshead Revisited, as well as a small part of Lewis Carroll's Alice's Adventures in Wonderland. More recently it has been used in the filming of the movies of J. K. Rowling's Harry Potter series and also the film adaptation of Philip Pullman's novel Northern Lights (the film bearing the title of the American edition of the book, The Golden Compass). Distinctive features of the college's architecture have been used as models by a number of other academic institutions, including the National University of Ireland, Galway, which reproduces Tom Quad. The University of Chicago and Cornell University both have reproductions of Christ Church's dining hall (in the forms of Hutchinson Hall and the dining hall of Risley Residential College, respectively). ChristChurch Cathedral in New Zealand, after which the City of Christchurch is named, is itself named after Christ Church, Oxford. Stained glass windows in the cathedral and other buildings are by the Pre-Raphaelite William Morris group with designs by Edward Burne-Jones

Matriculation examination

The term matriculation examination or matriculation exam refers to educational qualifications in many countries. Usually this has to do with student's transfer from secondary to tertiary education. For more detailed information, see "Matriculation".

Depending on country, matriculation examination can mean:

HIStory: Past, Present and Future, Book I

HIStory: Past, Present and Future, Book I (usually shortened to HIStory) is the ninth overall studio album and his fifth under Epic Records by American recording artist Michael Jackson. It was released on June 16, 1995 by Epic Records. This is Jackson's first album on his own label, MJJ Productions, and consists of two discs: the first disc (HIStory Begins) is a compilation of some of his greatest hits from 1979 onward, while the second disc (HIStory Continues) is a studio album composed entirely of new material. The majority of the second disc's tracks were written and produced by Jackson, often in conjunction with collaborators.

HIStory was Jackson's return to releasing music following the accusation of child sexual abuse in August 1993. Many of the 15 songs pertain to the accusations and Jackson's mistreatment in the media, specifically the tabloids. The songs' themes include environmental awareness, isolation, greed, suicide and injustice.

HIStory is Jackson's most controversial album. Jackson was accused of using anti-Semitic lyrics in "They Don't Care About Us". Jackson stated that he did not mean any offense and on multiple occasions denied anti-Semitism. The dispute regarding the lyrics ended with Jackson re-recording them. R. Kelly was accused of plagiarizing one of the album's songs, "You Are Not Alone". In 2007 a judge ruled that the song was plagiarized and the song was subsequently banned from radio stations in Belgium.

Schedule (computer science)

In the fields of databases and transaction processing (transaction management), a schedule (or history) of a system is an abstract model to describe execution of transactions running in the system. Often it is a list of operations (actions) ordered by time, performed by a set of transactions that are executed together in the system. If order in time between certain operations is not determined by the system, then a partial order is used. Examples of such operations are requesting a read operation, reading, writing, aborting, committing, requesting lock, locking, etc. Not all transaction operation types should be included in a schedule, and typically only selected operation types (e.g., data access operations) are included, as needed to reason about and describe certain phenomena. Schedules and schedule properties are fundamental concepts in database concurrency control theory.

Formal description

The following is an example of a schedule:

In this example, the horizontal axis represents the different transactions in the schedule D. The vertical axis represents time order of operations. Schedule D consists of three transactions T1, T2, T3. The schedule describes the actions of the transactions as seen by the DBMS. First T1 Reads and Writes to object X, and then Commits. Then T2 Reads and Writes to object Y and Commits, and finally T3 Reads and Writes to object Z and Commits. This is an example of a serial schedule, i.e., sequential with no overlap in time, because the actions of in all three transactions are sequential, and the transactions are not interleaved in time.

History (TV channel)

History (originally The History Channel, from 1995 to 2008) is an American basic cable and satellite television channel that is owned by A+E Networks, a joint venture between the Hearst Corporation and the Disney–ABC Television Group division of The Walt Disney Company.

It originally broadcast documentary programs and historical fiction series. However, since 2008, it has mostly broadcast a variety of reality television series such as Pawn Stars, Ax Men, and other non-history related content. Additionally, the network is frequently criticized by scientists, historians, and skeptics for broadcasting pseudo-documentaries, unsubstantiated and sensational investigative programming, such as Ancient Aliens, UFO Hunters, Brad Meltzer's Decoded and the Nostradamus Effect. As of February 2015, approximately 96,149,000 American households (82.6% of households with television) receive History.

International localized versions of History are available, in various forms, in India, Canada, Europe, Australia, Middle East, Africa, and Latin America. The first European version was launched in Scandinavia in 1997 by Viasat which now operates their own channel, Viasat History.
