Question: Michael Foale and Jean-Jacques Favier, have which job in common?

<P0-S0> STS-63 was the first mission of the US/Russian Shuttle-Mir Program, which carried out the first rendezvous of the American Space Shuttle with Russia's space station "Mir". <P0-S1>  Known as the 'Near-Mir' mission, the flight used Space Shuttle "Discovery", which lifted off from launch pad 39B on 3 February 1995 from Kennedy Space Center, Florida. <P0-S2>  A night launch and the 20th mission for "Discovery", it marked the first time a Space Shuttle mission had a female pilot, Eileen Collins, the first EVAs for both a UK born astronaut Michael Foale and a US astronaut of African heritage Bernard A. Harris, Jr. and it also carried out the successful deployment and retrieval of the Spartan-204 platform, along with the scheduled rendezvous and flyaround of "Mir", in preparation for STS-71, the first mission to dock with "Mir". <SEP> <P1-S0>  He is a veteran of six Space Shuttle missions and extended missions on both Mir and the International Space Station. <P1-S1> Colin Michael Foale, CBE (born 6 January 1957) is a British-American astrophysicist and former NASA astronaut. <P1-S2>  He was the first Briton to perform a space walk, and until 17 April 2008, he held the record for most time spent in space by a US citizen: 374 days, 11 hours, 19 minutes. <P1-S3>  He still holds the cumulative-time-in-space record for a UK citizen. <SEP> <P2-S0>  Favier was due to fly aboard the Columbia mission in 2003, but later signed out of the mission. <P2-S1> Jean-Jacques Favier (Born April 13, 1949) is a French engineer and a former CNES astronaut who flew aboard the STS-78 NASA Space Shuttle mission. <SEP> <P3-S0> In philosophy, economics, and political science, the common good (also commonwealth, common weal or general welfare) is a term of art, referring to either what is shared and beneficial for all or most members of a given community, or alternatively, what is achieved by citizenship, collective action, and active participation in the realm of politics and public service. <P3-S1>  The concept of the common good differs significantly among philosophical doctrines. <P3-S2>  Early conceptions of the common good were set out by Ancient Greek philosophers, including Aristotle and Plato. <P3-S3>  One understanding of the common good rooted in Aristotle's philosophy remains in common usage today, referring to what one contemporary scholar calls the "good proper to, and attainable only by, the community, yet individually shared by its members." <P3-S4>  The concept of common good developed through the work of political theorists, moral philosophers, and public economists, including Thomas Aquinas, Niccolò Machiavelli, John Locke, Jean-Jacques Rousseau, James Madison, Adam Smith, Karl Marx, John Stuart Mill, John Rawls, and many other thinkers. <P3-S5>  In contemporary economic theory, "a" common good is any good which is rivalrous yet non-excludable, while "the" common good, by contrast, arises in the subfield of welfare economics and refers to the outcome of a social welfare function. <P3-S6>  Such a social welfare function, in turn, would be rooted in a moral theory of the good (such as utilitarianism). <P3-S7>  Social choice theory aims to understand processes by which the common good may or may not be realized in societies through the study of collective decision rules. <P3-S8>  And public choice theory applies microeconomic methodology to the study of political science in order to explain how private interests affect political activities and outcomes.
