paragraph_text: The basis for classical economics forms Adam Smith's An Inquiry into the Nature and Causes of the Wealth of Nations, published in 1776. Smith criticized mercantilism, advocating a system of free trade with division of labour. He postulated an "invisible hand" that regulated economic systems made up of actors guided only by self-interest. Karl Marx developed an alternative economic theory, called Marxian economics. Marxian economics is based on the labor theory of value and assumes the value of good to be based on the amount of labor required to produce it. Under this assumption, capitalism was based on employers not paying the full value of workers labor to create profit. The Austrian school responded to Marxian economics by viewing entrepreneurship as driving force of economic development. This replaced the labor theory of value by a system of supply and demand.

paragraph_text: In 2018, the Social Security Wage Base was $128,400 and the Social Security tax rate was 6.20% paid by the employee and 6.20% paid by the employer. A person with $10,000 of gross income had $620.00 withheld as Social Security tax from his check and the employer sent an additional $620.00. A person with $130,000 of gross income in 2017 incurred Social Security tax of $7,886.40 (resulting in an effective rate of approximately 6.07% - the rate was lower because the income was more than the 2017 ``wage base '', see below), with $7,886.40 paid by the employer. A person who earned a million dollars in wages paid the same $7,886.40 in Social Security tax (resulting in an effective rate of approximately 0.79%), with equivalent employer matching. In the cases of the $130 k and $1 m earners, each paid the same amount into the social security system, and both will take the same out of the social security system.

paragraph_text: Baird Television Ltd. made Britain's first television broadcast, on 30 September 1929 from its studio in Long Acre, London, via the BBC's London transmitter, using the electromechanical system pioneered by John Logie Baird. This system used a vertically-scanned image of 30 lines – just enough resolution for a close-up of one person, and with a bandwidth low enough to use existing radio transmitters. Simultaneous transmission of sound and picture was achieved on 30 March 1930, by using the BBC's new twin transmitter at Brookmans Park. By late 1930, 30 minutes of morning programmes were broadcast Monday to Friday, and 30 minutes at midnight on Tuesdays and Fridays, after BBC radio went off the air. Baird broadcasts via the BBC continued until June 1932.

paragraph_text: After a series of test transmissions and special broadcasts that began in August 1936, the BBC Television Service officially launched on 2 November 1936 from a converted wing of Alexandra Palace in London. ``Ally Pally ''housed two studios, various scenery stores, make - up areas, dressing rooms, offices, and the transmitter itself, which then broadcast on the VHF band. BBC television initially used two systems on alternate weeks: the 240 - line Baird intermediate film system and the 405 - line Marconi - EMI system. The use of both formats made the BBC's service the world's first regular high - definition television service; it broadcast from Monday to Saturday between 15: 00 and 16: 00, and 21: 00 and 22: 00. The first programme broadcast -- and thus the first ever, on a dedicated TV channel -- was`` Opening of the BBC Television Service'' at 15: 00. The first major outside broadcast was the coronation of King George VI and Queen Elizabeth in May 1937.

paragraph_text: Over the past three centuries, hundreds of music notation systems have been proposed as alternatives to traditional western music notation. Many of these systems seek to improve upon traditional notation by using a ``chromatic staff ''in which each of the 12 pitch classes has its own unique place on the staff. Examples are the Ailler - Brennink notation, Jacques - Daniel Rochat's Dodeka music notation, Tom Reed's Twinline notation, Russell Ambrose's Ambrose Piano Tabs, Paul Morris' Clairnote, John Keller's Express Stave, and José A. Sotorrio's Bilinear Music Notation. These notation systems do not require the use of standard key signatures, accidentals, or clef signs. They also represent interval relationships more consistently and accurately than traditional notation. The Music Notation Project (formerly known as the Music Notation Modernization Association) has a website with information on many of these notation systems.

paragraph_text: On May 11, 2011, then Senate Majority Leader Harry Reid reintroduced the DREAM Act in the Senate. Some Republicans who had supported the bill in the past, including Sen. John Cornyn of Texas, Jon Kyl of Arizona, John McCain of Arizona, and Lindsey Graham of South Carolina, withheld their votes, objecting that such a bill should not be granted without increasing immigration enforcement. Reid indicated that he would consider adding a workplace enforcement measure in the DREAM Act that would require every employer to use E-Verify, the government's Internet - based work eligibility verification system. President Obama supported the bill as one of his efforts to reform the US immigration system.

paragraph_text: Köppen - Geiger climate classification system classifies its climate as hot desert (BWh). Luxor, Minya, Sohag, Qena and Asyut have the widest difference of temperatures between days and nights of any city in Egypt, with almost 16 ° C (29 ° F) difference. Sohag is one of the warmest places in Egypt due to its place in the east side of Sahara in North Africa. Sohag is ranked the 5th driest place in Egypt and the 9th globally. Also ranked 4th warmest place in Egypt and 296th globally.

paragraph_text: The Obusier de 6 pouces Gribeauval or 6-inch howitzer was a French artillery piece and part of a system established by Jean Baptiste Vaquette de Gribeauval. The Old French inch () was actually 1.066 English inches long so the weapon can accurately be described as a 6.4-inch howitzer. The Gribeauval system included the 6-inch howitzer, the light Canon de 4 Gribeauval, medium Canon de 8 Gribeauval and the heavy Canon de 12 Gribeauval. Superseding the older Vallière system, the Gribeauval system was introduced in 1765 and the guns were first used during the American Revolutionary War. The most comprehensive employment of Gribeauval guns occurred during the French Revolutionary Wars and the Napoleonic Wars. Two 6-inch howitzers were often added to four or six cannons to make up a battery of artillery in Napoleon's armies. The 6-inch howitzer was capable of firing an exploding shell at long-range targets or a canister shot at close-range enemy personnel. Starting in 1803, the Year XI system partly replaced the Gribeauval artillery, but it was not until 1829 that the Gribeauval system was wholly superseded by the Valée system.

paragraph_text: The two systems were to run on a trial basis for six months; early television sets supported both resolutions. However, the Baird system, which used a mechanical camera for filmed programming and Farnsworth image dissector cameras for live programming, proved too cumbersome and visually inferior, and ended with closedown (at 22:00) on Saturday 13 February 1937.

paragraph_text: The National Conference of State Legislatures held in Washington D.C. stated in a 2014 overview that many supporters for affirmative action argue that policies stemming from affirmative action help to open doors for historically excluded groups in workplace settings and higher education. Workplace diversity has become a business management concept in which employers actively seek to promote an inclusive workplace. By valuing diversity, employers have the capacity to create an environment in which there is a culture of respect for individual differences as well as the ability to draw in talent and ideas from all segments of the population. By creating this diverse workforce, these employers and companies gain a competitive advantage in an increasingly global economy. According to the U.S. Equal Employment Opportunity Commission, many private sector employers have concluded that a diverse workforce makes a "company stronger, more profitable, and a better place to work." Therefore, these diversity promoting policies are implemented for competitive reasons rather than as a response to discrimination, but have shown the value in having diversity.

paragraph_text: Evangelische Omroep (EO, English: "Evangelical Broadcasting") is one of the twelve member-based broadcasting associations contributing to the Netherlands Public Broadcasting system. It has as its mission to bring people into contact with Jesus Christ and its statement of faith is a form of Evangelicalism. EO is one of the few broadcasting associations in the "pillarized" Dutch broadcasting system to have remained totally faithful to its religious roots. For a long time every one of its programmes made reference to God and to the Christian religion, although this is less often the case in the 21st century.

paragraph_text: These symmetries express 9 distinct symmetries of a regular hexagon. John Conway labels these by a letter and group order. r12 is full symmetry, and a1 is no symmetry. d6, a isogonal hexagon constructed by four mirrors can alternate long and short edges, and p6, an isotoxal hexagon constructed with equal edge lengths, but vertices alternating two different internal angles. These two forms are duals of each other and have half the symmetry order of the regular hexagon. The i4 forms are regular hexagons flattened or stretched along one symmetry direction. It can be seen as an elongated rhombus, while d2 and p2 can be seen as horizontally and vertically elongated kites. g2 hexagons, with opposite sides parallel are also called hexagonal parallelogons.

paragraph_text: While considered "alternative" today, most alternative systems have existed since ancient times. After the public school system was widely developed beginning in the 19th century, some parents found reasons to be discontented with the new system. Alternative education developed in part as a reaction to perceived limitations and failings of traditional education. A broad range of educational approaches emerged, including alternative schools, self learning, homeschooling and unschooling. Example alternative schools include Montessori schools, Waldorf schools (or Steiner schools), Friends schools, Sands School, Summerhill School, The Peepal Grove School, Sudbury Valley School, Krishnamurti schools, and open classroom schools. Charter schools are another example of alternative education, which have in the recent years grown in numbers in the US and gained greater importance in its public education system.

Question: For how long did John Arlott's workplace alternate different broadcasting systems?
