Input: Consider Input: Verify if the sentiment of the following document towards the entity Medvedev is Positive . Russia's catastrophic wildfires this summer have demonstrated the need to reform the nation's forest protection legislation and the state forestry agency  President Dmitry Medvedev said Wednesday.
 The remarks appeared to reflect Medvedev's desire to take a higher profile on economic and domestic policy issues presently controlled by Prime Minister Vladimir Putin -- though Medvedev stopped short of an open challenge to his powerful predecessor and mentor.
 Putin has taken a highly visible lead in efforts to combat the fires  visiting affected areas and even taking a seat in a firefighting plane while Medvedev was chairing dull official meetings. Many political commentators perceived Putin's action as a sign of his intention to reclaim the presidency in 2012 and a clear warning to Mevedev to stand by.
 Medvedev indicated Wednesday that the prime minister's move to take direct control of the forestry agency  Rosleskhoz  could be insufficient to properly protect the nation's forests in the future.
 "If it's more convenient to work that way  you are welcome " Medvedev told a government meeting focused on forests. "But if it proves insufficient  I reserve the right to radically change those structures."
 He said the blazes had shown that the current law and the existing official structures can't properly protect the forests.
 "It's quite obvious that the legal base and the organizational structure that we have don't fit the purpose " Medvedev said in televised remarks.
 The president also said that the need for changing the current forest legislation also must be carefully analyzed.
Putin and Medvedev both have said they would decide later who will run for president.
 Medvedev avoided any direct criticism of Putin  but said Wednesday the 2006 law had left most of the nation's forests without due oversight.
 He also seemed to defy Putin on another issue -- the construction of a new highway northwest of Moscow that would destroy a forest near the town of Khimki. Putin's Cabinet has continued to support it despite growing public opposition.

Input: Consider Input: Verify if the sentiment of the following document towards the entity Ron Brown is Negative . "I can't teach the book right now " says Shaka Greene  algebra teacher at Ron Brown College Preparatory High School. "Because my students are still learning to add 49 plus 17."
So begins Part 3 — the conclusion of our podcast series: Raising Kings: A Year of Love and Struggle at Ron Brown College Prep.
For Greene  this is the last straw. He announces that he won't be returning for  Ron Brown's  second year because of  his  frustration over "egregiously" low academic expectations.
Curtis and Principal Williams insist that academic progress will come in this dramatically different school  but that no one should expect it so soon  after what is still Ron Brown's first year.
While Greene is the only teacher who says he won't be coming back because of these district policies  every member of the Ron Brown faculty agrees with his opposition.
This debate is not unique to Ron Brown. It has roiled teachers' lounges and principals' offices across the country.
The difficult truth for the passionate educators of Ron Brown is that both sides are right.
This is the last installment of our yearlong reporting project  "Raising Kings  A Year Of Love And Struggle At Ron Brown College Prep."

Input: Consider Input: Verify if the sentiment of the following document towards the entity Klaus Helmrich is Positive . “Initially there is a high number of players and then over time consolidation happens ”  Klaus Helmrich  said on Wednesday at the launch of a global user organization for Siemens’ MindSphere platform  which competes with General Electric’s Predix and others to help customers gather data from machines.
“I don’t think we will end up with one platform worldwide. There will be a handful or two handfuls in the mid to more distant future ”  Helmrich  said  comparing the proliferation of industrial software platforms with the smartphone industry  which has ended up being dominated by Apple and Samsung.
Siemens already has more than 800 000 intelligent sensors in buildings and machines  including trains and healthcare equipment  putting it in a strong position   Helmrich  said.
“It is a solid basis for the start of the business and makes us optimistic about scale effects ”  he  said  adding that being first to gather a critical mass of software developers and users is crucial to winning customers  much as Apple’s large developer community made its app store the most attractive.
