SYDNEY cheap adidas ultra boost uncaged black , Aug. 2 (Xinhua) -- Aussie researchers have unlocked the reason why adults use infant directed speech or baby talk, when addressing infants, according to a new study published Wednesday.


The Western Sydney University revealed that mother unconsciously raise the pitch of their voice as an evolutionary trait, in order to comfort their babies and make themselves appear friendlier.


It also helps babies learn language, as the sounds are clearer and easier to disseminate.


"What we found in this study was that mothers weren't actually making more exaggerated movements with their tongue to make the sound clearer cheap adidas ultra boost uncaged ," lead author Dr. Marina Kalashnikova told Xinhua on Wednesday.


"They were shortening the side of the vocal track and that was leading to a higher pitch in their voice and also clearer speech sounds."


The process recorded the sound characteristics of the eight mothers speech when talking to their babies and examined their lips and tongues with equipment that is used in the film industry to create digital effects, called electromagnetic articulography (EMA).


Data from the study was then measured against other research which has addressed similar behaviours across many different species, not just humans.


"The size of our vocal tract is characteristic of our body size, that's why women usually have a higher pitch than men," Kalashnikova said.


"You can also think about the sound a mouse makes with a really small vocal tract cheap adidas yeezy boost 350 v2 sale , compared to the roar of a large lion."


However just like human mothers, animals can modify how they sound in order to comfort their offspring.


"For example, when a large animal approaches their offspring, they can produce a higher pitched vocalization to sound smaller and less threatening," Kalashnikova said.


"But a smaller animal will produce a lower pitch of vocalization to sound bigger and scarier cheap adidas yeezy boost 350 v2 , so their young feel safe."


The evolutionary characteristic also appears to be universal across human languages.


According to Kalashnikova, similar research has concluded that Russian and Swedish languages also use baby talk and in the Asian community, "when mothers speak in Mandarin, they exaggerate the tone as well as their vowels."

VANCOUVER, Jan. 30 (Xinhua) -- A major breakthrough is needed in the renegotiations of the North American Free Trade Agreement (NAFTA) in order to keep the pact alive cheap adidas ultra boost 3.0 black , says a Canadian trade expert.


"There has to be some type of announcement related to an agreement within a major sector," said Michael Manjuris, a professor of economics and trade at Ryerson University in Toronto. "Maybe it will be the automotive sector because that seems to be the one we're all talking about."


Trade ministers from Canada, Mexico and the U.S. on Monday completed the sixth round of NAFTA negotiations in Montreal, with lead officials noting that some progress was made cheap adidas ultra boost 3.0 , but adding that tough challenges remain ahead of a new deal.


Something like a breakthrough in the auto sector "will have to come out in the next round to show that there is real progress and we're not going to turn to a political fight in having [NAFTA] cancelled," Manjuris told Xinhua in an interview.


U.S Trade Representative Robert Lighthizer in his closing remarks after the weekend meeting said they took a step forward in this latest round, but he also criticized Canada for its recent launch of a challenge against U.S. trade practises with the WTO.


He called the complaint "unprecedented" and a "massive attack on all of our trade laws," according to Canadian news reports.


Last month, Canada's government launched the wide-ranging 32-page complaint to the WTO cheap adidas tubular , accusing the U.S. of imposing unfair anti-dumping and anti-subsidy duties against Canadian products.


Canada said U.S. broke the WTO's Anti-Dumping Agreement, the Agreement on Subsidies and Countervailing Measures, the General Agreement on Tariffs and Trade, and the Understanding on Rules and Procedures Governing the Settlement of Disputes.


Manjuris said the complaint will have certainly sparked interest from other nations around world.


At the World Economic Forum in Davos last week, U.S. President Donald Trump claimed success for his first year in office and said America remains open for business cheap adidas nmd xr4 sale , resisting his apparent urge to exclaim his America-first protectionist rhetoric he has often repeated on U.S. soil.


As for NAFTA, Manjuris said the negotiators are now getting into the tough elements of bargaining such as the auto sector, dispute settlement and rules of origin.


"The fact that they're still talking tells me that both sides have been putting forward positions that are in some way trying to move them closer to an agreement," he said.


The next round of talks will likely be held in Mexico in late February.


"Think about what they're saying. They're cautiously optimistic because they're going to talk again," Manjuris said. "That's a pretty low bar."


But there remains reason for optimism cheap adidas nmd xr4 , he added, noting that several American business people, members of congress and senators attended the Montreal meeting.


"They're trying to push the idea that NAFTA is good for the Americans," he said. "We've actually seen the participants in the agreement come forward and say this is important to us and we need to keep it."


"At least they're putting forth proposals to each other trying.
