[Q]: Verify if the sentiment of the following document towards the entity Paul Khairy is Negative . The excitement of sports is likely responsible for the observed increases in heart rate  said study author Dr. Paul Khairy  a cardiologist at the Montreal Heart Institute.
But the new study is the first to demonstrate that the ambience of a live game â being surrounded by cheering fans  being closer to the action and experiencing an increased level of engagement â may all contribute to the heightened emotional stress response in fans   Khairy  told Live Science.
In the study  the heart rates of fans who watched a hockey game in person increased by 110 percent  on average  from their resting heart rates. That's comparable to the increase you'd see in someone running  jumping rope or doing any other vigorous form of exercise   Khairy  said.
Fans who watched the same game on TV had a 75 percent increase in their heart rates  on average  which is similar to the heart rates seen with moderate physical activity  such as a casual bike ride   Khairy  noted.
Surprisingly  a person's interest in the sport and engagement as a fan were not linked to changes in heart rate during the game   Khairy  said. However   he  added that  he  suspects there might have been a different result if researchers had developed their own way to measure passion in hockey fans rather than adapting a tool originally designed for soccer spectators.
Although fans watching any sport can experience a similar amount of excitement as was observed in this group of hockey enthusiasts  these results may not apply to other sports   Khairy  said. There are too many elements that differ among sports â such as the pace of the game  a fan's emotional attachment to a team  and even the number of high-intensity moments â that prevent researchers from making similar generalizations   he  said.
A fan's emotional reaction to a game can be intense   Khairy  said  and that could trigger cardiovascular problems.
Fans who experience cardiac symptoms during a game should seek immediate medical attention rather than waiting for a convenient moment  such as in-between periods   Khairy  said. Many arenas and ice rinks have cardiac defibrillators on hand  as well as people trained in using them   he  added.

[Q]: Verify if the sentiment of the following document towards the entity Tom Cotton is Positive . Sen. Tom Cotton (R-Ark.) arrives for a weekly Republican Party luncheon at the U.S. Capitol on Jan. 17. (Jonathan Ernst/Reuters).
 Sen. Tom Cotton (R-Ark.)  last week helped kill the bipartisan immigration deal in Congress.  He  didn't think the bill went far enough in transforming the U.S. immigration system. Like President Trump   Cotton  thinks the United States should cut legal immigration. The senator's reasoning?
âIt can't simultaneously be true that robots will take all the jobs & that the West needs millions of new immigrants to do the grunt work â tweeted  Cotton  in late January  quoting a Wall Street Journal op-ed from a conservative commentator.
âI think itâs certainly critical that we reduce unskilled and low-skilled workers. It canât both be true ... that we need both more unskilled and low-skilled workers  but robots are going to take all the jobs â  Cotton  told Vox.
âTom Cotton is woefully misinformed â said Joe Brusuelas  chief economist at RSM. âRobots will create more jobs.â

[Q]: Verify if the sentiment of the following document towards the entity Warren Buffett is Positive . Start with the story of one particularly troublesome Washington-area gifted child  Warren Buffett  as described in the biography "The Snowball " by Alice Schroeder. By age 13  Buffett  later to be the richest man in the world and a Washington Post Co. board member  had had it with school. I wonder whether it might have been better had his parents let him quit right then.
 At newspaper gatherings  Buffett sometimes mentions the Washington Post paper route he had as a boy. It sounds quaint and charming  until you read the book and discover that the kid had so many routes that his annual income (including proceeds from his tenant farm and other investments) was greater than that of his teachers at his junior and senior high schools. His father was a congressman  his family was comfortable  but he had made all that money himself as a boy genius entrepreneur. By age 14  he had filed his first tax return.
 The only teacher who got through to Buffett was the school golf coach  and only because he took the student to the racetrack in Charles Town  W.Va.  where the future investment guru tested his theories on speed handicapping. Buffett's grades improved only because his father threatened to end his newspaper delivery business if he did not shape up.
 These days  we have many fine teachers trained to help gifted children. Many parents are happy that their children have been designated gifted. But we have no data to show that such children wouldn't be better off if they were just taken to the library and told to read anything they liked. That was how Buffett spent much of his time  devouring volumes on every imaginable subject  including every business book he could find.
