Ex Input:
Context_1 : Electoral history of Sarah Palin, Governor of Alaska (2006-2009) and Republican vice presidential nominee in the 2008 United States presidential election. Context_2 : In 1973, Republican Vice President Spiro Agnew was forced to resign following a controversy over his personal taxes. Under the terms of the 25th Amendment, a vice presidential vacancy is filled when the president nominates a candidate who is confirmed by both houses of Congress. Republican President Richard Nixon thus had the task of selecting a vice president who could receive the majority support of both houses of Congress. Nixon considered selecting former Texas Governor John Connally, New York Governor Nelson Rockefeller, and California Governor Ronald Reagan. However, Nixon settled on House Minority Leader Gerald Ford of Michigan, who was popular among the members of Congress and who was good friends with Nixon. Ford won the approval of both houses by huge margins, and was sworn in as the 40th Vice President of the United States on December 6, 1973. In 1974, Ford ascended to the presidency after the Watergate scandal led to the resignation of President Nixon. Context_3 : The United States presidential election of 1996 was the 53rd quadrennial presidential election. It was held on Tuesday, November 5, 1996. The Democratic national ticket was led by incumbent President Bill Clinton, and his running mate, incumbent Vice President Al Gore. The Republican nominee for President was Bob Dole, the former Republican Leader of the United States Senate and long-time Senator from Kansas who was previously the vice-presidential running mate of President Gerald Ford in 1976, following Vice President Nelson Rockefeller's retirement from politics that year. Dole's running mate for Vice President was Jack Kemp, a former NFL football player and the Housing Secretary under George H. W. Bush. Businessman Ross Perot ran as candidate for the Reform Party with economist Pat Choate as his running mate; he received less media attention and was excluded from the presidential debates and, while still obtaining substantial results for a third-party candidate, by U.S. standards, did not renew his success of the 1992 election. Turnout was registered at 49.0%, the lowest for a presidential election since 1924. Context_4 : Electoral history of Bob Dole, United States Senator from Kansas (19691996), Senate Majority Leader (19851987, 19951996), Senate Minority Leader (19871995), 1976 Republican Party Vice Presidential nominee and 1996 Presidential nominee. Context_5 : "Drill, baby, drill!" was a 2008 Republican campaign slogan first used at the 2008 Republican National Convention by former Maryland Lieutenant Governor Michael Steele, who was later elected Chairman of the Republican National Committee. The slogan expressed support for increased drilling for petroleum and gas as sources of additional energy and gained further prominence after it was used by Republican Vice Presidential nominee Sarah Palin during the vice-presidential debate. Context_6 : The 1976 Republican National Convention was a United States political convention of the Republican Party that met from August 16 to August 19, 1976, to select the party's nominee for President. Held in Kemper Arena in Kansas City, Missouri, the convention nominated President Gerald Ford for a full term, but only after narrowly defeating a strong challenge from former California Governor Ronald Reagan. The convention also nominated Senator Robert J. Dole of Kansas for Vice President, instead of Vice President Nelson Rockefeller. The keynote address was delivered by Tennessee Senator Howard Baker. Other notable speakers included Minnesota Representative Al Quie, retired Lieutenant Colonel and former Vietnam prisoner of war Raymond Schrump, former Texas Governor John Connally, Providence, Rhode Island mayor Vincent Cianci and Michigan Senator Robert P. Griffin. It is the last national convention by either of the two major parties to feature a seriously contested nomination between candidates. Context_7 : In 1974, Republican President Richard Nixon was forced to resign following the Watergate Scandal. Vice President Gerald Ford ascended to the presidency, leaving the office of vice president vacant. Under the terms of the 25th Amendment, a vice presidential vacancy is filled when the president nominates a candidate who is confirmed by both houses of Congress. On August 20, 1974, Ford announced his nomination of former New York Governor Nelson Rockefeller to fill the vacancy. Ford also considered picking Tennessee Senator Howard Baker and former Republican National Committee Chairman George H.W. Bush. Rockefeller was generally considered to be a liberal Republican, and Ford decided that picking Rockefeller would help his candidacy gain support in the 1976 presidential election. The confirmation hearings for Rockefeller lasted for months, but Rockefeller was sworn in as the 41st Vice President of the United States on December 19, 1974. Due to the pressure on Ford by the party conservatives, Rockefeller was ultimately passed over for the 1976 ticket, and Ford instead chose Bob Dole as his running mate. Ford, however, regreted this move later. Context_8 : This debate featured U.S. Senator Walter Mondale from Minnesota, the Democratic vice presidential nominee, and U.S. Senator Bob Dole from Kansas, the Republican vice presidential nominee. Context_9 : Charles Warren Fairbanks (May 11, 1852 June 4, 1918) was an American politician who served as the 26th Vice President of the United States from 1905 to 1909 and a Senator from Indiana from 1897 to 1905. He was also the Republican vice presidential nominee in the 1916 presidential election. Context_10 : Robert Joseph Dole (born July 22, 1923) is an American lawyer and politician who represented Kansas in Congress from 1961 to 1996 and served as the Republican Leader of the United States Senate from 1985 until 1996. He was the Republican presidential nominee in the 1996 presidential election and the party's vice presidential nominee in the 1976 presidential election. fact_1 : The convention also nominated Senator Robert J. Dole of Kansas for Vice President, instead of Vice President Nelson Rockefeller. fact_2 : Robert Joseph Dole (born July 22, 1923) is an American lawyer and politician who represented Kansas in Congress from 1961 to 1996 and served as the Republican Leader of the United States Senate from 1985 until 1996.

Context_1 : The Trussed Concrete Steel Company was a company founded by Julius Kahn, an engineer and inventor. The company manufactured prefabricated products for reinforced concrete beams and steel forms for building reinforced concrete floors and walls. Kahn invented and patented a unique new technology reinforcement system of construction called the Kahn System that was stronger, more economical, and lighter than the existing old school technology used up to that point to construct buildings. The old method was to use plain straight smooth steel beams or loose rods or stirrups in concrete beams and floors. Kahn's new technology improved system used 45 degree tab flanges or "wings" permanently attached on steel beams that distributed the tension stress for overall improvement in strength of reinforced concrete. Context_2 : Estanisalao Tovilla-Cortazar (19361994) was a Mexican Civil Engineer born in February 10, 1936 in Mexico City, Mexico. He died in Veracruz, Mexico in March 8, 1994. He is most remembered for his research and development contributions in pier and pile foundations and soil mechanics. Tovilla-Cortazar's engineering work included the development of new foundation techniques at port sites and large industrial construction sites such as the Veracruz Port and the Steel Company Las Truchas (SICARTSA) in Lazaro Cardenas, Michoacan, Mexico and in SIDOR, Puerto Ordaz, Venezuela. He also developed contract closure procedures and audit for large construction contracts. Context_3 : Hy-Rib was a brand name for a product manufactured by the Trussed Concrete Steel Company. It is an engineering reinforcement system for floors, walls, and ceilings of buildings and houses. This product is a derivative of the Kahn Trussed Bar for beams and columns that was invented by Julius Kahn. Kahn engineered the Hy-Rib products and they were first manufactured in 1909. Context_4 : William Walker Scranton (April 4, 1844 December 3, 1916) was an American businessman based in Scranton, Pennsylvania. He became president and manager of the Lackawanna Iron and Coal Company after his father's death in 1872. The company had been founded by his father's cousin George W. Scranton. Among his innovations, Scranton adopted the Bessemer process for his operations in 1876, greatly increasing production of steel ties with a new mill. Scranton founded the Scranton Steel Company, in 1891 consolidated as Lackawanna Iron and Steel Company. The steel company became the second largest in the nation. He later also managed the Scranton Gas and Water Company, developing a secure water supply outside the city by creating Lake Scranton. Context_5 : Albert Kahn Associates is an architectural design firm in Detroit, Michigan with a second office located in Sao Paulo, Brasil. It was established in 1895 and is still active today. It introduced a new technology in industrial building involving a unique reinforced concrete method referred to as the Kahn System of construction using proprietary patented reinforcement steel manufactured by Trussed Concrete Steel Company. The building of automobile factories and other types of factories were revolutionized from wooden timber framing construction. Besides being an advanced technology in strength that led to wider open interior spaces, it featured a high degree of fire resistance and larger window space for light. The firm started by Albert Kahn built factories for Chrysler for over a decade, Ford Automobile for 30 years and Packard Automobile for 35 years. Other important clients of the firm were Republic Steel and General Motors. The firm was awarded a $40 million dollar contract to build a tractor factory in Russia in 1928. The firm's output was over a million dollars worth of work per week by 1929. By 1939, the firm designed 19 percent of all industrial buildings in the United States and had designed some $800million of buildings worldwide. Currently, Albert Kahn Associates is still making history with state-of-the-art projects. Recent projects include creating the world's largest penguin conservatory,located at the Detroit Zoo, which opened in 2016. Context_6 : The Lackawanna Steel Company was an American steel manufacturing company that existed as an independent company from 1840 to 1922, and as a subsidiary of the Bethlehem Steel company from 1922 to 1983. Founded by the Scranton family, it was once the second-largest steel company in the world (and the largest company outside the U.S. Steel trust). Scranton, Pennsylvania developed around the company's original location. When the company moved to a suburb of Buffalo, New York, in 1902, it stimulated the founding of the city of Lackawanna. Context_7 : Truscon Laboratories was a research and development chemical laboratory of the Trussed Concrete Steel Company ("Truscon") of Detroit, Michigan. It made waterproofing liquid chemical products that went into or on cement and plaster. The products goals were to provide damp-proofing and waterproofing finishing for concrete and Truscon steel to guard against disintegrating action of water and air. Context_8 : Frederick J. Griffiths (December 11, 1878 - October 17, 1951) was an early, English-born engineer in the Stark County, Ohio steel industry. He is best known for working with Henry Ford to develop a vanadium alloy steel in order to produce lighter-weight, stronger automobiles. When the Massillon Rolling Mill Company merged into the Central Steel Company in June 1914, Griffiths resigned as a chemist at Canton's United Steel Company to become Central's vice president and superintendent. He then became the president of the company. His daughter, Gertrude, lit the first open hearth furnace at the new Central Steel Company in 1915. In 1917, Griffith's was named to the Massillon Steel Casting Company board of directors. The company's earliest orders came from the United States military for production of the steel-rated equipment and supplies needed for World War I. By 1919, 3 of his 5 brothers were all superintendents at Central Steel. Context_9 : Benjamin Franklin Fairless (May 3, 1890 January 1, 1962) was an American steel company executive.

The project, which became operational in 2008, is a scientific collaboration between the Portuguese and Spanish governments, but it is open to the general public and scientific community, both within and beyond the Iberian Peninsula. The project's name is a portmanteau of "Iberia" and the Latin word "civis", meaning "citizen". Context_4 : Scientific collaboration network is a social network where nodes are scientists and links are co-authorships as the latter is one of the most well documented forms of scientific collaboration. It is an undirected, scale-free network where the degree distribution follows a power law with an exponential cutoff most authors are sparsely connected while a few authors are intensively connected. The network has an assortative nature hubs tend to link to other hubs and low-degree nodes tend to link to low-degree nodes. Assortativity is not structural, meaning that it is not a consequence of the degree distribution, but it is generated by some process that governs the network's evolution.
