full_context: Document 1: Blackjack: Once all the players have completed their hands, it is the dealer's turn. The dealer hand will not be completed if all players have either busted or received Blackjacks. The dealer then reveals the hidden card and must hit until the cards total 17 or more points. (At most tables the dealer also hits on a ``soft ''17, i.e. a hand containing an ace and one or more other cards totaling six.) Players win by not busting and having a total higher than the dealer, or not busting and having the dealer bust, or getting a blackjack without the dealer getting a blackjack. If the player and dealer have the same total (not counting blackjacks), this is called a`` push'', and the player typically does not win or lose money on that hand. Otherwise, the dealer wins.
Document 2: Harvard University: Harvard's 2,400 professors, lecturers, and instructors instruct 7,200 undergraduates and 14,000 graduate students. The school color is crimson, which is also the name of the Harvard sports teams and the daily newspaper, The Harvard Crimson. The color was unofficially adopted (in preference to magenta) by an 1875 vote of the student body, although the association with some form of red can be traced back to 1858, when Charles William Eliot, a young graduate student who would later become Harvard's 21st and longest-serving president (1869–1909), bought red bandanas for his crew so they could more easily be distinguished by spectators at a regatta.
Document 3: Boston: Boston is sometimes called a "city of neighborhoods" because of the profusion of diverse subsections; the city government's Office of Neighborhood Services has officially designated 23 neighborhoods.
Document 4: Boston: Boston is an intellectual, technological, and political center but has lost some important regional institutions, including the acquisition of The Boston Globe by The New York Times, and the loss to mergers and acquisitions of local financial institutions such as FleetBoston Financial, which was acquired by Charlotte-based Bank of America in 2004. Boston-based department stores Jordan Marsh and Filene's have both been merged into the Cincinnati–based Macy's. Boston has experienced gentrification in the latter half of the 20th century, with housing prices increasing sharply since the 1990s. Living expenses have risen, and Boston has one of the highest costs of living in the United States, and was ranked the 129th most expensive major city in the world in a 2011 survey of 214 cities. Despite cost of living issues, Boston ranks high on livability ratings, ranking 36th worldwide in quality of living in 2011 in a survey of 221 major cities.
Document 5: New York City: New York is a global hub of international business and commerce. In 2012, New York City topped the first Global Economic Power Index, published by The Atlantic (to be differentiated from a namesake list published by the Martin Prosperity Institute), with cities ranked according to criteria reflecting their presence on similar lists as published by other entities. The city is a major center for banking and finance, retailing, world trade, transportation, tourism, real estate, new media as well as traditional media, advertising, legal services, accountancy, insurance, theater, fashion, and the arts in the United States; while Silicon Alley, metonymous for New York's broad-spectrum high technology sphere, continues to expand. The Port of New York and New Jersey is also a major economic engine, handling record cargo volume in the first half of 2014.
Document 6: McKinsey & Company: McKinsey consultants published Creative Destruction in 2001. The book suggested that CEOs need to be willing to change or rebuild a company, rather than protect what they have created. It found that out of the first S&P 500 list from 1957, only 74 were still in business by 1998. The New York Times said it ``makes a cogent argument that in times of rampant, uncertain change... established companies are handcuffed by success. ''In 2009, McKinsey consultants published`` The Alchemy of Growth'', which established three ``horizons ''for growth: core enhancements, new growth platforms and options. Its three horizons became adopted widely, because it gave executives a simple vocabulary about business growth.
Document 7: Boston: Several universities located outside Boston have a major presence in the city.

Its business, medical, dental, and public health schools are located in Boston's Allston and Longwood neighborhoods. Harvard has plans for additional expansion into Allston. The Massachusetts Institute of Technology (MIT), which originated in Boston and was long known as "Boston Tech", moved across the river to Cambridge in 1916. Tufts University, whose main campus is north of the city in Somerville and Medford, locates its medical and dental school in Boston's Chinatown at Tufts Medical Center, a 451-bed academic medical institution that is home to both a full-service hospital for adults and the Floating Hospital for Children.

Document 9: Monitor Deloitte: Prior to its acquisition by Deloitte in January 2013, Monitor Deloitte was an American strategy consulting practice known as Monitor Group, which filed for chapter 11 bankruptcy in 2012. Monitor Group was founded in 1983 by six entrepreneurs with ties to the Harvard Business School, including Michael Porter. The advisory services now offered by Monitor Deloitte are in line with Monitor Group's legacy expertise, but expanded to a broader set of implementation and capabilities design focused on greater resilience to economic uncertainty.
Document 10: Boston: Federally, Boston is split between two congressional districts. The northern three-fourths of the city is in the 7th district, represented by Mike Capuano since 1998.

The state's senior member of the United States Senate is Democrat Elizabeth Warren, first elected in 2012. The state's junior member of the United States Senate is Democrat Ed Markey, who was elected in 2013 to succeed John Kerry after Kerry's appointment and confirmation as the United States Secretary of State.
