WASHINGTON air force 1 sale , Feb. 11 (Xinhua) -- In her first testimony to the Congress, U.S. Federal Reserve Chair Janet Yellen reiterated central bank's plan to taper its stimulus exit despite recent weakness in the economy.
The current economic situation and outlook, as well as the monetary policy, were the main focus of the hearing held twice a year.
Yellen told lawmakers she expected "a great deal of continuity" in the central bank's monetary policy, saying that she served on the Fed policy-setting committee as the bank formulated its current policy strategy and she strongly supported that strategy.
Yellen Men's Nike Air Force 1 Flyknit Low Grey Sale , 67, took the oath of office to lead the Federal Reserve System on Feb. 3, succeeding Ben Bernanke, who stepped down after eight turbulent years. She was previously the Fed's vice Chair.
In the public debut in her new role, Yellen said while the economy gained steam at the end of 2013 Men's Nike Air Force 1 Flyknit Low Red Sale , recovery in the U.S. labor market was "far from complete," underscoring the importance of considering more than just the unemployment rate when evaluating the conditions of the labor market.
Her point of keeping an eye on wider range of labor indicators is particularly important as the unemployment rate, now at 6.6 percent, is near the 6.5 percent threshold the Fed once identified as the level that would need to be reached before officials would consider a hike in the interest rates.
"If coming information broadly supports the Committee's expectation of ongoing improvement in labor market conditions and inflation moving back toward its long-run objective, the Committee will likely reduce the pace of asset purchases in further measured steps at future meetings Nike Air Force 1 Flyknit Low All White Sale ," Yellen indicated steady pullback in Fed stimulus, referring to the Federal Open Market Committee, which sets monetary policy.
While admitting she was "surprised" by the two recent jobs reports that showed the pace of job creation running under what she had expected, Yellen cautioned against jumping to conclusions of the longer trend. She told the Congress that the Fed needs to see a "notable change" in the economic outlook to consider pausing its withdrawal of stimulus.
The Fed trimmed its monthly purchases of Treasury and mortgage- backed securities by a total of 10 billion dollars in both December and January, citing strengthening economy and continued improvement in the labor market.
The Fed policymakers have suggested they would continue to reduce the bond buying Men's Nike Air Force 1 Flyknit Low Blue Sale , which now totals 65 billion dollars a month, at a similar pace at each Fed meeting and end it by the end of 2014, provided the economy develops generally in line with expectations.
Yellen also highlighted the Fed's financial regulatory role, saying that the work of making the financial system more robust " has not yet been completed."
LONDON, March 27 (Xinhua) -- Bigger brains help social primates to make up after a fight Women's Nike Air Force One High Red Sale , research at the University of Manchester revealed Monday.
Social primates with bigger brains are likely to use their added cerebral power to cope with conflict, the study showed.
The university said the surprise findings suggest that social skills, which are very sophisticated in primates, help individuals cope with aggression and competition caused by living in large groups.
The study, published in the journal Behavioral Ecology Men's Nike Air Force One High Red White Sale , was led in Manchester by Veronica Cowl, a PhD student based in the university's School of Earth and Environmental Sciences.
Cowl looked at the associations between group size, brain size and behaviours that are recognised as "prosocial" and "cooperative", such as working together as a group on a collective action, and their relationship to aggressive behaviours that led to incidents of conflict Men's Nike Air Force One High White Black Sale , termed as agonism.
The three species with very high levels of agonism are chacma baboons, capuchins and a population of black and white ruffed lemurs.
The species with the lowest rates of agonism were brown lemurs and black howler monkeys.
Earlier studies examined how variation primate agonism related to ecological variables, such as risks from predators or food competition.
The Manchester team was interested in explaining why there is strong association between brain size and group size in primates.
Cowl said: "Our research indicates that the increase in brain size is likely to be a consequence of high levels of competition in large groups. It seems that large brained primates have had to develop strategies to cope with high rates of conflict."
"This is of particular importance as primates are noted for their social cognition -- for example, they are able to understand social relationships between individuals, track social relationships and can develop social strategies."
The Manchester researchers also saw different patterns between the overall level of agonism in a group and the amount of conflict between any two individuals within the group.
Cowl added that this suggests that either individuals in larger groups can buffer aggression better or that only species with low levels of dyadic conflict can maintain large groups and stable social relationships.
Dr Susanne Shultz Nike Air Force One Low Men's White Blue Sale , the senior author on the paper, said: "Now we have shown that big brains, big groups and conflict are related to each other, this helps to answer an enduring puzzle about why primates in larger groups have larger brains.
"It seems large-brained primates have evolved to cope with the challenges of conflict and coordination inherent in living in large groups."
