Input: Consider Input: Verify if the sentiment of the following document towards the entity Stanley Fischer is Positive . Federal Reserve Vice Chair Stanley Fischer  announced last week  he  was resigning for personal reasons before the end of  his  term  opening yet another seat in the central bank's powerful board for President Donald Trump to fill.
The departure of  Fischer   73  represents a big loss of institutional knowledge and gravitas for the Fed at a time when many American institutions are sorely lacking in technocratic expertise.  Fischer  is considered the leader of a generation of prominent academic and professional economics  in part because  he  taught many of them at MIT.
" He  is often referred to as the dean of central bankers  having taught most central bankers including former Fed Chairman Ben Bernanke and European Central Bank president Mario Draghi " Shawn Baldwin  the chairman of AIA Group  wrote in a LinkedIn post. " Fischer 's departure creates a vacuum not easily filled  adding to the uncertainty in monetary policy."
Larry Summers  the Harvard economist and former Treasury secretary  dubbed  Fischer 's resignation "the end of an era."
Fischer  who was born in Zambia and later studied in London  started his career as an academic but became a policymaker at the World Bank and later the International Monetary Fund  where he rose to the role of first deputy managing director.  Fischer  then spent three years at Citigroup as a vice chairman before moving to Israel in 2005 to become the head of its central bank.  Fischer  returned to the US as Fed vice chairman in 2014.  His  term was not set to end until June 2018.
"The Fed and the international monetary system will be weaker for  his  departure from official responsibility " Summers wrote in a blog post.
" Stan 's has been a singular career "  he  said. "As an MIT professor he coauthored  with  his  close friend Rudi Dornbusch  the macro textbook that defined the basics of the field for a generation. With Olivier Blanchard " the former IMF chief economist  "he wrote the treatise that defined the state of the art for graduate students. His lectures were models of lucid exposition and balanced judgment. My view of monetary economics was shaped by my experience auditing his class in the Fall of 1978."
Not everyone is complimentary about the arc of  Fischer 's career. To some  he represents the kind of establishment economics that led to financial instability and income inequality in many parts of the world.
During his time at the IMF   Fischer  became the face of austerity measures gone wrong. Many of his and the IMF's recommendations for drastic spending cuts during the Asian financial crisis of the late 1990s have since been widely discredited as having made matters worse.
"I see  Fischer  as to a large extent the embodiment of the conventional wisdom among macroeconomists and central bankers " said Dean Baker  the director of the Center for Economic and Policy Research  a liberal Washington think tank. " He  also  in the pre-crisis days  was very much associated with the deregulation of finance gang  although I think  he  has developed an appreciation of the need for regulation since the crisis."
Indeed   Fischer  has spoken out rather strongly against efforts by Trump and Republicans to unwind most of the key regulations imposed on Wall Street after the crisis with the aim of preventing a repeat performance.
"We seem to have forgotten that we had a financial crisis  which was caused by behavior in the banking and other parts of the financial system  and it did enormous damage to this economy "  Fischer  told CNBC in April  just as the president was signing an executive order aimed at what  he  said was "reviewing" Dodd-Frank.
"Millions of people lost their jobs  millions of people lost their houses "  Fischer  said. "This was not a small-time  regular recession. This was huge  and it affected the rest of the world  and it affected  to some extent  our standing in the world as well. We should not forget that."
Baker says  Fischer  did a good job in Israel  where  he  managed the central bank from 2005 to 2013.
" He  pushed down the value of the shekel  giving the country a large trade surplus  which allowed it to get through the Great Recession with little damage " Baker said.
As for US monetary policy   his  tenure did not include much action on the part of the Fed  but  Fischer  has been erroneously worried about the threat of looming inflation since the start of  his  tenure.

Input: Consider Input: Verify if the sentiment of the following document towards the entity Tim Stevens is Neutral . A wide field of view  about 150 degrees  is helpful. But if itâs too extreme  like a fisheye lens  you start to lose details  said Tim Stevens  editor-in-chief of Roadshow  the automotive segment for CNET  a consumer technology website.
âI think thatâs pretty important â  Stevens  said  along with high-resolution.
 Stevens  said neither of those features worked very well in the dash cams  he 's tested.
âIf anything  they just get to be annoying because theyâre beeping all the time  and you just want to turn them off â  he  said.

Input: Consider Input: Verify if the sentiment of the following document towards the entity Murad Alam is Positive . "The scientists looking at appearance changes found that the upper and lower cheeks were full after the study " said study author  Dr. Murad Alam   vice chair in the department of dermatology at the Northwestern University Feinberg School of Medicine in Chicago.
"Patients themselves found even greater benefits  and noticed that 18 of the 20 areas and features of the face that were studied got better over the course of the study "  Alam  said. "In general  the appearance benefit was that the contour of the face became smoother  fuller and firmer."
The findings were published in January in the journal JAMA Dermatology.  Alam  noted that none of the researchers had a financial interest in the facial yoga exercise program.
As for whether men or perhaps younger women might achieve a similar benefit   Alam  said  "we would expect to see an effect. But until we study it we won't know if it is a little more or a little less."
Still  exercise alone may not be enough "to replace the tried-and-tested methods of improving facial appearance" that can be achieved with fillers  lasers and the like   Alam  acknowledged. Instead  exercises might best serve to enhance such interventions   he  said.
But  Xu  said that facial exercise "makes a lot of intuitive sense."
Why? "Facial aging is so much more than just seeing more wrinkles on the face " said  Xu . "It's a complex process  and includes thinning of the upper layers of the skin  loss of collagen and elastin in the deeper layers of the skin  and loss of fat and muscle.
