[EX Q]: Verify if the sentiment of the following document towards the entity Tim Clark is Neutral . Emirates Airline president Sir Tim Clark .  REUTERS/Satish Kumar
Emirates Airline president Sir Tim Clark  believes the US aviation industry would suffer if the system of Open Skies agreements falls apart.
 Clark  says international demand for air travel and aircraft have skyrocketed since the first of more than 120 Open Skies agreements were signed in 1992.
 Emirates Airline president Sir Tim Clark  believes the US aviation industry could become a victim of the trade dispute centered around the Open Skies agreements that govern air travel between the US and the United Arab Emirates where  his  airline is based.
 This  Clark  believes  threatens to weaken the network of Open Skies agreements that have served the aviation industry so well over the past couple of decades.
REUTERS/Satish Kumar "When the US went Open Skies I thought it was the best thing because if the US had done it then everybody would follow suit "  Clark  told us.
"I know that as a result of what they did  the number of planes Boeing sold went nuclear "  Clark  declared. "Because the number of aircraft sold was a direct function of the Open Skies versus closed skies relationship."

[EX Q]: Verify if the sentiment of the following document towards the entity Chris Christie is Negative . Outgoing Gov. Chris Christie  said Tuesday that New Jersey needed "tough and plain-spoken leadership" when  he  took office eight years ago and  he  delivered it  pulling the state from "the brink of financial ruin" by confronting problems leaders of both parties had ignored for decades.
 Christie  hands over state government to Democrat Phil Murphy in a week.
 Christie  said  he  was the first governor in America to try to tackle the huge and escalating burden of state pension costs  saying previous governors from both parties and Legislatures "virtually ignored the growing menace of increased costs and no real contributions." Among the steps taken during  his  administration was dedicating lottery proceeds to the pension system for the next 30 years.
When  he  took office   Christie  said  New Jersey was "on the brink of financial ruin as a state."
"We needed tough and plain-spoken leadership to deal with these problems "  he  said.
 He  said  he  vetoed more than $7 billion in spending  helped cut the state workforce  pushed through a cap on property tax increases and  at the same time  made sure the state invested heavily to help protect the New Jersey Shore from the kind of devastation it suffered during Superstorm Sandy in 2012.
The prepared text of  his  remarks didn't show  him  invoking the name of  his  friend  President Donald Trump. But  he  called it an "honor" to chair the White House's opioid commission.
 Christie 's speech caps  his  stint as one of America's best-known governors.
 He  was on the cover of Time magazine under the headline "The Boss" and a periodic guest on late-night television  where  he  memorably appeared in a skit about "dad dancing" with Jimmy Fallon and poked fun at  his  weight by eating a doughnut on David Letterman's show.
At least in the beginning   he  won acclaim for  his  forthrightness  like when  he  told beachcombers to "get the hell off the beach" in 2011 during Hurricane Irene.  He  told it like it was before Trump brought the practice to the White House.
 He  also was exceedingly popular and widely praised for guiding the state in its recovery from Superstorm Sandy  which ravaged the coastline.  He  was briefly seen as a top GOP contender for president.
But  he  was also criticized for testy exchanges with the public during town hall meetings and other encounters.
 His  popularity and job approval fell sharply  particularly after the George Washington Bridge lane closure scandal in which three of  his  allies were convicted in a political retribution scheme.  He  also lost the home crowd after spending much of 2015 and early 2016 campaigning for president out of state  a contest  he  dropped out of after failing to emerge from the back of the pack.
 He  returned to New Jersey and focused on the state's â and country's â opioid addiction crisis after failing to get a top job in the Trump administration. A regular theme in  his  remarks around the state included "second chances " and the idea that people can make a comeback.

[EX Q]: Verify if the sentiment of the following document towards the entity Mellanox is Neutral .

Starboard became the biggest shareholder in Mellanox after disclosing its stake purchase - valued at around $300 million - and said the chipmaker could improve its financial performance.
In particular  Starboard is concerned that Mellanox  which makes computer networking products using InfiniBand and Ethernet technology  rejected a potential merger with rival Marvell Technology. Starboard  in its filing  said Marvell had expressed interest in discussing a “potential strategic transaction” but  Mellanox  declined to enter into talks.
 Mellanox’s  shares opened 14 percent higher and were still up 11 percent at $56.65 by 1552 GMT.  They  had risen 25 percent this year through Monday  underperforming Marvell’s 56 percent rally and a 48 percent increase in the Philadelphia Semiconductor index.
The source noted that  Starboard - which believes Mellanox is spending too much on research and development and other corporate expenses to try to boost revenue  sacrificing margins compared with peers - must stop disappointing investors .
“ They  need to improve financial performance or sell the company. Either way it is to see the stock price go up significantly ” the source said  noting there was a “long list of potential buyers” for Mellanox.
 Mellanox  which was founded in 1999 and has a market value of nearly $3 billion   said in a statement on Tuesday that  it  “welcomes the input and investment” from all  its  shareholders.
“In line with our commitment to drive enhanced shareholder value  the Mellanox board of directors and management team continually review our operational and strategic priorities and are committed to acting in the best interests of our shareholders ” it said.
Barclays analyst Joseph Wolf  who downgraded  Mellanox  to “underweight” after  its  earnings report  said that while there is room for  Mellanox  to cut expenses   its  growth stems from accelerating revenue during product transitions.
