IN: Girls Aloud are an English-Irish pop girl group, which was created through the ITV talent show Popstars: The Rivals in 2002. The group comprised singers Cheryl, Nadine Coyle, Sarah Harding, Nicola Roberts and Kimberley Walsh. The group achieved a string of twenty consecutive top ten singles in the United Kingdom, including four number ones.

The group Girls Aloud was formed on 30 November 2002, in front of millions of viewers on ITV's Popstars: The Rivals. The concept of the programme, hosted by Big Brother presenter Davina McCall was to produce a boyband and a girlgroup who would be "rivals" and compete for the 2002 Christmas number one single. Following the initial success of Hear'Say (winners of the original Popstars show), several thousand applicants attended auditions across the United Kingdom in hope of being selected. Ten girls and ten boys were chosen as finalists by judges Pete Waterman, Louis Walsh and Spice Girls member Geri Halliwell. However, two of these were disqualified before the live shows began: Hazel Kaneswaran was found to be too old to participate while Nicola Ward refused to sign the contract, claiming the pay the group would receive was too low. Kimberley Walsh and Nicola Roberts, who had made it into the final fifteen but not the final ten, were chosen as their replacements. During October and November, the finalists took to the stage participating in weekly Saturday night live performances (alternating week-by-week between the girls and boys). Each week the contestant polling the fewest phone votes was eliminated, until the final line-ups of the groups emerged. The five girls who made it into the group were (in the order announced by the host) Cheryl, Nicola, Nadine, Kimberley and Sarah; Javine Hylton missed out on a place in the group, despite previous expectations that she would be placed in the line-up. The group was named Girls Aloud and were managed by Louis Walsh until 2005 when Hilary Shaw replaced him. The new group competed with the boys' winning group, One True Voice to have 2002's Christmas number one single. Girls Aloud won the battle with their single "Sound of the Underground", produced by Brian Higgins and Xenomania. The song spent four consecutive weeks at number one and was certified platinum in March 2003. The song received critical acclaim; Alexis Petridis of The Guardian stated that "it proved a first: it was a reality pop record that didn't make you want to do physical harm to everyone involved in its manufacture".

IN: Irving Fisher (February 27, 1867 - April 29, 1947) was an American economist, statistician, inventor, and Progressive social campaigner. He was one of the earliest American neoclassical economists, though his later work on debt deflation has been embraced by the Post-Keynesian school. Joseph Schumpeter described him as "the greatest economist the United States has ever produced", an assessment later repeated by James Tobin and Milton Friedman. Fisher made important contributions to utility theory and general equilibrium.

Fisher was born in Saugerties, New York. His father was a teacher and a Congregational minister, who raised his son to believe he must be a useful member of society. Despite being raised in religious family, he later on became an atheist. As a child, he had remarkable mathematical ability and a flair for invention. A week after he was admitted to Yale College his father died, at age 53. Irving then supported his mother, brother, and himself, mainly by tutoring. He graduated first in his class with a B.A degree in 1888, having also been elected as a member of the Skull and Bones society. In 1891, Fisher received the first Ph.D. in economics granted by Yale. His faculty advisors were the theoretical physicist Willard Gibbs and the sociologist William Graham Sumner. As a student, Fisher had shown particular talent and inclination for mathematics, but he found that economics offered greater scope for his ambition and social concerns. His thesis, published by Yale in 1892 as Mathematical Investigations in the Theory of Value and Prices, was a rigorous development of the theory of general equilibrium. When he began writing the thesis, Fisher had not been aware that Leon Walras and his continental European disciples had already covered similar ground. Nonetheless, Fisher's work was a very significant contribution and was immediately recognized and praised as first-rate by such European masters as Francis Edgeworth. After graduating from Yale, Fisher studied in Berlin and Paris. From 1890 onward, he remained at Yale, first as a tutor, then after 1898 as a professor of political economy, and after 1935 as professor emeritus. He edited the Yale Review from 1896 to 1910 and was active in many learned societies, institutes, and welfare organizations. He was president of the American Economic Association in 1918. The American Mathematical Society selected him as its Gibbs Lecturer for 1929. A leading early proponent of econometrics, in 1930 he founded, with Ragnar Frisch and Charles F. Roos the Econometric Society, of which he was the first president. Fisher was a prolific writer, producing journalism as well as technical books and articles, and addressing various social issues surrounding of the First World War, the prosperous 1920s and the depressed 1930s. He made several practical inventions, the most notable of which was an "index visible filing system" which he patented in 1913 and sold to Kardex Rand (later Remington Rand) in 1925. This, and his subsequent stock investments, made him a wealthy man until his personal finances were badly hit by the Crash of 1929. Fisher was also an active social and health campaigner, as well as an advocate of vegetarianism, Prohibition, and eugenics. He died in New York City in 1947, at the age of 80.
