 "The main goal is not only to preserve the relations existing between our states  but to give them a new impulse " he added.
 Medvedev hailed Hu's visit as "friendly and constructive " adding these were qualities "that characterise relations between our two countries."
 The Chinese president ended his talks with the Russian for "Thank You".
 Medvedev and Putin did not mention these figures  instead citing bilateral trade with China worth over 55 billion dollars in 2008.
 China and Russia also agreed to boost the use of their domestic currencies in trade  Medvedev added  as Moscow seeks to lessen the global dominance of the US dollar.

Question: Verify if the sentiment of the following document towards the entity Dante de Kort is Positive . Last winter   Dante de Kort -- an eight-year-old boy who lives in central Arizona --  found a dead collared peccary  a wild pig-like animal  near  his  house.  He  set up a motion-controlled camera nearby  and over the next ten days  was surprised to discover footage of the peccary's herd returning to visit their dead herd-member  over and over.
When  he  wrote up  his  findings in a school science-fair presentation  it caught the attention of local biologist Mariana Altricher. It looked like the wild pecarries were in mourning  which was surprising: Scientists have seen grief-like behavior in animals like elephants  dolphins and primates  which are known for their high level of intelligence. But never in these creatures  as National Geographic reports:
Having studied the social  pig-like mammals for years  Altrichter knew how tightly bonded peccaries could be. But she'd never witnessed herd members return to a body repeatedly ... “It was pretty amazing because it wasn’t just an immediate reaction and then they moved on—it went on for 10 days ” says Altrichter  chair of the International Union for Conservation of Nature’s Peccary Specialist Group. [snip] In the videos  the peccaries pay close attention to the body  nuzzling  biting  sniffing  and staring at it. They slept next to the carcass  and even tried to lift it by wedging their snouts under the body and pushing upward. And when a pack of coyotes approached their fallen peer  the herd chased them away. “It really surprised me that they would stand up to the coyotes ” says  de Kort   noting the peccaries were outnumbered.
Altricher used the video evidence to write a scientific paper -- "Collared peccary (Pecari tajacu) behavioral reactions toward a dead member of the herd" -- that lists  de Kort  as its lead author.

Answer: yes


Question: Verify if the sentiment of the following document towards the entity Pincus is Negative . "We had a fundamental belief that  if people found games at their fingertips  if you really reduced the barriers to entry to games and you made them social  then a much larger group would engage " said Mark Pincus   44  who founded Zynga in January 2007 .
He was indisputably farsighted in recognizing the opportunity  and has been rewarded with a company that could pull down a half billion in revenue in its fourth year. There's rampant speculation the company will go public  an event that would propel Pincus into the leagues of the region's superrich.
Zynga boasts 208.8 million active players per month on Facebook  and could reach $500 million in revenue this year  estimates research firm Inside Network . The company has been profitable since it was nine months old  Pincus said.
In a blog post following the TechCrunch articles  Pincus stressed that the company worked hard to remove "bad offers" and said the worst offender had been permanently banned before the articles appeared. He committed to take additional steps to prevent questionable ads.
"The ads involved were created by third parties  not Zynga  and were removed more than a year ago  before the case was filed " he said.
Shortly after the flareup over the lead generation offers  an online video came to light that suggested the company had knowingly allowed such ads. It showed Pincus speaking at a Berkeley event in 2009.
"I funded the company myself but I did every horrible thing in the book to just get revenues right away " he said. "I mean we gave our users poker chips if they downloaded this wiki toolbar."
"I downloaded it once  I couldn't get rid of it  " he said. "We did anything possible to just get revenues so that we could grow and be a real business."
"We want to build an Internet treasure " Pincus replied. "We want to build one of the trusted brands on the Internet. If you look at our actions  they speak louder than our words and hopefully louder than my bad words."
Pincus  who previously founded Freeloader  Support.com and Tribe.net.
He also suspected the most engaged users would be willing to pay money for virtual goods like coins  tractors or weapons that allowed them to more rapidly advance or "level up" in the games  or simply enjoy them more.
He was right.
Pincus and other executives say they outmaneuvered the marketplace by designing better games  adjusting them based on how people were actually playing  and spending heavily on technology  customer service and marketing.

no
