Question: Copeland and Florence and the Machine, have which mutual related occupation type?
Context: Florence and the Machine (stylised as Florence + the Machine) are an English indie rock band that formed in London in 2007, consisting of lead singer Florence Welch, keyboardist Isabella Summers, and a collaboration of other artists.  The band's music received praise across the media, especially from the BBC, which played a large part in their rise to prominence by promoting Florence and the Machine as part of "BBC Introducing".  At the 2009 Brit Awards they received the Brit Awards "Critics' Choice" award.  The band's music is renowned for its dramatic and eccentric production and also Welch's powerful vocal performances. The Florentine banking family of the Cerchi, minor nobles of the Valdarno, with a seat especially at Acone near Pontassieve, settled in Florence in the early thirteenth century and increased their fortunes.  The family became the heads of a consortium of the prominent Guelfs that securely controlled Florence after the battle of Benevento in 1266.  In Florence, the Cerchi purchased some of the ancient structures in the closely packed inner city formerly belonging to the counts Guidi, cheek-by-jowl with the proud Florentine family of the Donati, with whom their growing mutual antagonism was expressed in violent episodes that polarized Florence within a couple of decades in a virtual civil war that aligned behind two captains, Corso Donati of the "Neri" Guelf faction— the "Black" Guelfs of the old noble oligarchy— and Vieri de' Cerchi of the "Bianchi", the moderate party that represented itself as champions of working people (the "magri").  The resulting violence lasted, with irruptions of tranquility, into the fourteenth century. Copeland is an American rock band formed in 2001 by the singer, pianist Aaron Marsh (who also plays guitar) with his friend, the bass guitarist and backing vocalist James Likeness, in Lakeland, Florida. The Type 97 heavy tank machine gun (九七式車載重機関銃 , Kyū-nana-shiki shasai jū-kikanjū ) was the standard machine gun used in tanks and armored vehicles of the Imperial Japanese Army during World War II, a heavy machine gun by infantry forces, This weapon was not related to the Type 97 aircraft machine gun used in several Japanese Navy aircraft including the A6M Zero. Mutual knowledge is a fundamental concept about information in game theory, (epistemic) logic, and epistemology.  An event is mutual knowledge if all agents know that the event occurred.  However, mutual knowledge by itself implies nothing about what agents know about other agents' knowledge: i.e. it is possible that an event is mutual knowledge but that each agent is unaware that the other agents know it has occurred.  Common knowledge is a related but stronger notion; any event that is common knowledge is also mutual knowledge. The Copeland House is important as an example of a vernacular farm residence built in the Carolina back country after 1790, along what would in the early 19th century become an established coach road from the coastal counties to the interior.  Constructed in the late 18th century by John Jacob Copeland (1775-1853), it became the center for his family that grew to include eight children.  The house and the nearby farms, many belonging to families related by marriage over time, became significant contributors to a German Lutheran settlement in the area which took shape in this part of South Carolina a generation before the start of the American Revolution.  The nearest town, Ehrhardt, South Carolina, is about 2 miles east of the Copeland House.  The residence, initially built in the early 1790s, is significant for its association with the Copeland family, who built the house, occupied it continuously and farmed the surrounding property for nearly 200 years.  In the mid-1980s the Copeland descendants, heirs to the fifth generation of the family, sold the property.  The original square log and dovetail construction remains largely intact, even after several significant 19th and early 20th century modifications and additions were made.  Subsequent owners have generally maintained the original fabric while stabilizing the structure.  The house, together with several related dependencies and an adjacent Copeland family burial site, was listed in the National Register of Historic Places on October 18, 1991. The linotype machine ( ) is a "line casting" machine used in printing sold by the Mergenthaler Linotype Company and related companies.  It was a hot metal typesetting system that cast blocks of metal type for individual uses.  Linotype became one of the mainstay methods to set type, especially small-size body text, for newspapers, magazines and posters from the late 19th century to the 1970s and 1980s, when it was largely replaced by phototypesetting, offset lithography printing and computer typesetting.  The name of the machine comes from the fact that it produces an entire line of metal type at once, hence a "line-o'-type", a significant improvement over the previous industry standard, "i.e.", manual, letter-by-letter typesetting using a composing stick and drawers of letters. Mutual knowledge in game theory is information known by all participatory agents.  However, unlike common knowledge, a related topic, mutual knowledge does not require that all agents are aware that this knowledge is mutual.  All common knowledge is mutual knowledge, but not all mutual knowledge is common knowledge.  Mutual knowledge can arise accidentally, due to a failure to design the game properly, so all players independently discover this mutual knowledge, or deliberately, due to the expected course of the game. Tell Neba'a Litani or Neba'a Litani is a medium size tell 9 km west of Baalbek in the northern Beqaa Valley of Lebanon.  I It is located near the spring which is the main source of the Litani River at a height of 1002 m .  It was first studied by Lorraine Copeland and Peter Wescombe in 1965-1966 and is accessible via a road which turns from Hoch Barada to the left.  Materials recovered included flint tools such as scrapers and the blade from a segmented sickle.  Pottery included burnished, painted and red washed shards, some with incised decoration or lattice patterns.  The material resembled finds from Byblos and Ard Tlaili leading Copeland and Wescombe to suggest a late Neolithic occupation for the tell that extended into the Bronze Age. A 130–30 fund or a ratio up to 150/50 is a type of collective investment vehicle, often a type of specialty mutual fund, but which allows the fund manager simultaneously to hold both long and short positions on different equities in the fund.  Traditionally, mutual funds were long-only investments.  130–30 funds are a fast-growing segment of the financial industry; they should be available both as traditional mutual funds, and as exchange-traded funds (ETFs).  While this type of investment has existed for a while in the hedge fund industry, its availability for retail investors is relatively new.
