Thomson Reuters Corporation (/ˈrɔɪtərz/) is a major multinational mass media and information firm founded in Toronto, Ontario, Canada and based in New York City and Toronto. It was created by the Thomson Corporation's purchase of British-based Reuters Group on 17 April 2008, and today is majority owned by The Woodbridge Company, a holding company for the Thomson family. The company operates in more than 100 countries, and has more than 60,000 employees around the world. Thomson Reuters was ranked as Canada's "leading corporate brand" in the 2010 Interbrand Best Canadian Brands ranking. Thomson Reuters' operational headquarters are located at 3 Times Square, Manhattan, New York City; its legal domicile is 333 Bay Street, Suite 400, Toronto, Ontario.
The company was founded by Roy Thomson in 1934 in Ontario as the publisher of The Timmins Daily Press. In 1953 Thomson acquired the Scotsman newspaper and moved to Scotland the following year. He consolidated his media position in Scotland in 1957 when he won the franchise for Scottish Television. In 1959 he bought the Kemsley Group, a purchase that eventually gave him control of the Sunday Times. He separately acquired the Times in 1967. He moved into the airline business in 1965, when he acquired Britannia Airways and into oil and gas exploration in 1971 when he participated in a consortium to exploit reserves in the North Sea. In the 1970s, following the death of Lord Thomson, the company withdrew from national newspapers and broadcast media, selling the Times, the Sunday Times and Scottish Television and instead moved into publishing, buying Sweet & Maxwell in 1988. The company at this time was known as the International Thomson Organisation Ltd (ITOL).
A top is a toy designed to be spun rapidly on the ground, the motion of which causes it to remain precisely balanced on its tip because of inertia. Such toys have existed since antiquity. Traditionally tops were constructed of wood, sometimes with an iron tip, and would be set in motion by aid of a string or rope coiled around its axis which, when pulled quickly, caused a rapid unwinding that would set the top in motion. Today they are often built of plastic, and modern materials and manufacturing processes allow tops to be constructed with such precise balance that they can be set in motion by a simple twist of the fingers and twirl of the wrist without need for string or rope.
The motion of a top is produced in the most simple forms by twirling the stem using the fingers. More sophisticated tops are spun by holding the axis firmly while pulling a string or twisting a stick or pushing an auger. In the kinds with an auger, an internal weight rotates, producing an overall circular motion. Some tops can be thrown, while firmly grasping a string that had been tightly wound around the stem, and the centrifugal force generated by the unwinding motion of the string will set them spinning upon touching ground.
In the context of a module M over a ring R, the top of M is the largest semisimple quotient module of M if it exists.
For finite-dimensional k-algebras (k a field), if rad(M) denotes the intersection of all proper maximal submodules of M (the radical of the module), then the top of M is M/rad(M). In the case of local rings with maximal ideal P, the top of M is M/PM. In general if R is a semilocal ring (=semi-artinian ring), that is, if R/Rad(R) is an Artinian ring, where Rad(R) is the Jacobson radical of R, then M/rad(M) is a semisimple module and is the top of M. This includes the cases of local rings and finite dimensional algebras over fields.
A top is clothing that covers at least the chest, but which usually covers most of the upper human body between the neck and the waistline. The bottom of tops can be as short as mid-torso, or as long as mid-thigh. Men's tops are generally paired with pants, and women's with pants or skirts. Common types of tops are t-shirts, blouses and shirts.
The neckline is the highest line of the top, and may be as high as a head-covering hood, or as low as the waistline or bottom hem of the top. A top may be worn loose or tight around the bust or waist, and may have sleeves or shoulder straps, spaghetti straps (noodle straps), or may be strapless. The back may be covered or bare. Tops may have straps around the waist or neck, or over the shoulders.
