CHICAGO Mattia Perin World Cup Jersey , Nov. 20 (Xinhua) -- Brain's dynamic properties, how it is wired and also how that wiring shifts in response to changing intellectual demands, are the best predictors of intelligence in the human brain, a study of the University of Illinois (UI) found.


"There are the pathways that encode prior knowledge and experience Mattia De Sciglio World Cup Jersey , which we call 'crystallized intelligence.' And there are adaptive reasoning and problem-solving skills that are quite flexible, called 'fluid intelligence,'" said UI psychology professor Aron Barbey, who hosted the study.


Crystallized intelligence involves robust connections Matteo Darmian World Cup Jersey , the result of months or years of neural traffic on well-worn pathways. Fluid intelligence involves weaker, more transient pathways and connections that are formed when the brain tackles unique or unusual problems.


"Rather than forming permanent connections, we are constantly updating our prior knowledge, and this involves forming new connections Marco Parolo World Cup Jersey ," Barbey said. The more readily the brain forms and reforms its connectivity in response to changing needs, the better it works, he said.


Researchers have long known that flexibility is an important characteristic of human brain function. But only recently has the idea emerged that flexibility provides the basis for human intelligence.


General intelligence requires not only the ability to flexibly reach nearby and easy-to-access states to support crystallized intelligence, but also the ability to adapt and reach difficult-to-access states to support fluid intelligence Manolo Gabbiadini World Cup Jersey , Barbey said.


"What my colleagues and I have come to realize is that general intelligence does not originate from a single brain region or network. Emerging neuroscience evidence instead suggests that intelligence reflects the ability to flexibly transition between network states," he said.


The study has been published in the journal Trends in Cognitive Sciences.

VIENNA, May 11 (Xinhua) -- Werner Faymann's abrupt resignation both as Austrian chancellor and head of the Social Democrats is only the end of the beginning of the political strife within his party over how to deal with the emerging right-wing populist Freedom Party.


In 1986, Social Democrat Chancellor Franz Vranitzky made a doctrine that the party should not enter into coalition with the Freedom Party. But today some Social Democrats believe that the doctrine puts the party in despair.


The reality is, the Social Democrat-People's Party coalition may not be able to retain majority in elections as a result of the growing weight of the Freedom Party, which has gained from the refugee crisis.


As many Social Democrats have switched to the Freedom Party over the last years, some Social Democrats want a substantive re-orientation toward the Freedom Party.


In an open criticism, Linz Mayor Klaus Luger, a Social Democrat, has said that his party has transformed into ""an ideological sect"" and that the ""red traditionalists uphold dusty dogmas.""


Social Democrat Hans Niessl, governor of Burgenland, is already ruling in coalition with the Freedom Party.


On the other hand, sects within the Social Democrats, especially youth organizations, remain adamant. They demand a clear voice in the refugee debate and clear distance from the Freedom Party.


Faymann, unfortunately, was caught in the crossfire within his party. A year ago, he followed in German Chancellor Angela Merkel's footsteps in the European refugee crisis, adopting an open-arms policy. But as public opinion changed, Faymann and his administration had to argue for restrictive measures. The change of policy angered the left-wing of his party.


Faymann was crushed between the two camps. Some accused him of being too dogmatic with regard to the Freedom Party, while others would not forgive him for the refugee policy change.


In addition, Faymann had to take responsibility for the Social Democrat failures in numerous elections, resulting in his sudden resignation.


Faymann's successor will face the onerous task of bringing the different sects within the party together in face of an increasingly aggressive Freedom Party.

Customs authorities at Shenzhen's Luohu Port, South China's Guangdong Province, announced on Monday that they have detained a female Hong Kong resident who tried to smuggle hundreds of ivory items through customs.

According to a custom officer Luca Antonelli World Cup Jersey , the Hong Kong resident's luggage, including a bag and two bottles of wine, was subject to X-ray scanning at the border.

During the screening, a suspicious shadow was spotted at the bottom of her bag Lorenzo Insigne World Cup Jersey , which turned out to be a package labeled "artwork."

As many as 276 ivory items, including carvings and cigarette holders, were found in the package.

The total weight of the seized contraband is around 7 kilograms, the China News Service reported Monday.

The trade and sale of ivory carvings is legal only if the ivory comes from items imported to China before the country signed the Convention on International Trade in Endangered Species of Wild Fauna and Flora (CITES) in 1981 or from 62 tons of raw ivory bought from four African countries in 2008 Lorenzo De Silvestri World Cup Jersey , as permitted by CITES.

Raw ivory and products made from it can only be legally processed and sold at designated places by designated vendors, and each product must be individually cataloged and tracked with its own unique photo ID.

In the first seven months of this year, the custom authorities of Luohu Port, which accounts for more than 30 percent of the Chinese mainland's inbound and outbound passengers Leonardo Bonucci World Cup Jersey , busted 51 cases in which products made from endangered species including bear bile, ivory and red coral were being smuggled, 50 percent more year-on-year, said a custom official at the port.
