Internet porn means birds 'n' bees talk comes earlier, says expert
Internet 
8 hours ago
Featurepics.com
A boy works on a laptop.
A father recently sat down to have "the talk" with his 10-year-old son. After he got through the basics on the birds and the bees, the boy asked, "Why do men wear masks when they're having sex?"
Though the father said he had parental controls engaged on his iPad, the son managed to find a fetish site depicting men in masks.
As the anecdote told by sex educator Cindy Gallop so plainly illustrates, kids look at porn. Kids look at porn on the Internet. And yes, let's go further: Your kids look at porn on the Internet. Gross? Probably, yes. But it's reality.
Keeping your kids from Internet porn is practically impossible, experts agree. Whether kids under 18 deliberately searched out sexually explicit sites, or stumbled upon them accidentally, approximately 40 percent see Internet porn every year, the study found. And yes, all that exposure does leave a mark: "Although research is scarce, investigators see links between young people who access Web porn and unhealthy attitudes toward sex," the American Psychological Association noted in 2007.
But parents don't have to be powerless. Explaining to your kids that difference between pornography and what goes on between consenting adults in real life is key, say some sex educators. You won't want to do it. Your kid won't want to hear it. And unfortunately, because of the Internet, that conversation has to come sooner rather than later. But it may make all the difference to kids when they're grown.
"This is not because 8-year-olds go looking for porn, it's a function of what they're shown on someone's cellphone on the playground, what happens when they go out to the neighbor's house," said Gallop, a fervent proponent of reality-based sex education. Preparing kids for a healthy sex life as adults was part of her message Saturday at "The Future of Porn" talk at South by Southwest Interactive in Austin.
Gallop is CEO and founder of Make Love Not Porn, a website dedicated to correcting sexual misconceptions picked up by viewers of professional for-profit pornography. The Internet venture does this, in part, by curating videos of "real sex" uploaded to the platform by "real people" ? not "porn stars." (Obviously, the video portion of the website is for adults only.) But as Gallop emphasized, the misconceptions picked up through pornography can start at a very young age.
"It doesn't matter what parental controls you put in place, kids live their lives in other places ... or an 8-year-old does something really cute and innocent. They discover a new naughty word and they Google it." Next thing you know, Gallop pointed out, that curious boy or girl is one or two clicks away from something he or she is too young to understand.
The exposure may result in relationships that lack scope and communication. "Too many young people start their sexual careers attempting to duplicate porn, not realizing that this model lacks so much," noted sex educator and author Dr. Marty Klein recently wrote in the Huffington Post.
"With valuable face-to-face communication increasingly replaced by brief digital syllables ... young adults' ability to simply talk about what goes on in bed ... is lagging further and further behind the needs of their sexual encounters ? whether hookup or more intimate."
Kids don't want to hear a lot of things. They don't want to hear that they shouldn't drive too fast or date the mean hot person or eat fast food all the time. But if the Internet is going to put your kids in the path of a virtual tsunami of porn, the least you can do is warn them about it.
Helen A.S. Popkin goes blah blah blah about the Internet. Tell her to get a real job on Twitterand/or Facebook.

PFT: Dolphins reportedly 'lead dog' for Wallace
APThe Steelers finally drew a line in the sand Saturday, and released outside linebacker James Harrison when he became too expensive.
But over the past few years, they?ve stretched out a number of contracts, willing to push money onto future caps to keep a core of players together.
According to Mark Kaboly of the Pittsburgh Tribune-Review, the Steelers have restructured 13 deals since the lockout ended in August 2011, pushing $54.7 million onto future salary cap ledgers.
During that span, they?ve adjusted the deals of quarterback Ben Roethlisberger three times, linebacker Lawrence Timmons twice; and once each for Antonio Brown, Heath Miller, Chris Kemoeatu, Harrison, Brett Keisel, LaMarr Woodley, Ike Taylor and Willie Colon once.
That works, as long as the group of players they?ve chosen produce together. But there?s an inherent risk as well, as it creates a top-heavy roster that?s hard to fix if a bad thing happens, especially with the salary cap flattening in the post-lockout world.
?They are trying to get as much flexibility as they can during the transition years,? said Andrew Zimbalist, an economics professor at Smith College in Massachusetts. ?(The fact that) they are engaging in this more than they have in the past is attributable to adjustments to the ? cap.?
Playing kick-the-can with the salary cap can lead to a disaster at some point. But the Steelers are able to get away with this institutionally for two main reasons.
One, they have a quarterback in Roethlisberger who is good enough to raise a team a level, from average to good or good to great.
Secondly, they have scouted and drafted well enough to have star players and also find contributors deep in drafts to replace players when they get too expensive.
If a Jason Worilds can replace Harrison?s production (as Harrison did when he replaced Joey Porter), and Roethlisberger never gets hurt again, it?s a system that can work, considering they have an excellent coach and general manager.
But it does leave one of the league?s most stable franchise vulnerable to the one thing even the smartest team can?t account for ? bad luck.

Obama staying out of negotiations on gun bills

WASHINGTON (AP) ? With gun legislation taking shape on Capitol Hill, President Barack Obama has kept a low profile on an issue he has made a critical part of his second-term agenda.
The president has not been highly visible in the debate during the past three weeks as gun bills are being written. He's been embroiled in a budget battle that has dominated his time and for now is letting Vice President Joe Biden bang the drum for tighter firearms laws.
White House officials say the president plans to speak out on gun control as the issue moves toward a Senate vote in the coming weeks. But for now, he's staying out of delicate negotiations among lawmakers. The White House says he will become more vocal if the legislative process hits a roadblock.
Obama called for a gun control vote in his State of the Union address on Feb. 12 and followed up three days later with a speech on shooting violence in his murder-plagued hometown of Chicago. He's barely mentioned gun control publicly in the time since, other than during a minute of remarks Thursday, shortly after a Senate committee approved a bill to increase gun trafficking penalties. He thanked the senators who supported it and urged other lawmakers to pass it into law.
"I urge Congress to move on other areas that have support of the American people ? from requiring universal background checks to getting assault weapons off our streets ? because we need to stop the flow of illegal guns to criminals," Obama said before signing a revitalized Violence Against Women Act. The Senate Judiciary Committee plans to resume voting on gun bills Tuesday, including an assault weapons ban and background checks that Obama wants.
Biden, a multi-decade veteran of negotiations over gun laws, has been more vocal in the White House's gun-control campaign with speeches, interviews and private negotiations.
Biden regularly meets with and calls his former Senate colleagues to talk about guns, including holding a White House meeting last week with Sen. Tom Coburn, R-Okla., in which they discussed negotiations on background checks that could win support from Republicans. He's even gotten involved at the state level by calling legislators in places like Colorado that are debating gun legislation. And when Obama convened the first Cabinet meeting of his second term earlier this week, he said he would turn the floor over to Biden to talk about their gun initiatives.
Matt Bennett, spokesman for gun-control proponent Third Way, said it's good for Obama himself not to get too involved because he's seen as such a lightning rod on the issue and might stir up more opposition from Republicans. "We don't want Republican attitudes about him to get in the way of a deal," Bennett said.
There's polling to back up that point. When the Pew Research Center asked about Obama's gun proposals in January, 31 percent felt Obama's proposals on guns go too far, 13 percent said they didn't go far enough and 39 percent said they're about right. But a majority of respondents to an Associated Press-GfK poll around the same time indicated support for his proposals when his name wasn't attached to them ? 84 percent in favor of standard background checks, 55 percent favoring a ban on military-style rapid-fire guns and 51 percent supporting a ban on the sale of high-capacity magazines holding 10 or more bullets.
Despite the high public support, all the measures face a tough fight that will require a well-coordinated campaign to pass in a Congress that has a tradition of defending gun ownership rights.
That campaign is being run out of the Eisenhower Executive Office Building, located next to the White House, where the vice president's staff meets each week with representatives of gun-control groups around a leather-covered conference table. The administration officials and the advocates share updates on the debate and work with Justice Department attorneys on language they can support in the legislation.
Among those who attend are Mayors Against Illegal Guns, a group started by New York Mayor Michael Bloomberg; Third Way, a centrist organization that advocates on many issues including gun control; the Brady Campaign to Prevent Gun Violence, named after the White House press secretary seriously wounded in the assassination attempt on President Ronald Reagan in 1981; and Americans for Responsible Solutions, recently started by former Rep. Gabrielle Giffords, D-Ariz., and her husband, Mark Kelly.
Mark Glaze, a lobbyist for the mayors' group, said the White House is doing something right ? whether it's by keeping Biden at the forefront or by Obama hanging back. "Whatever they are doing or not doing is working," Glaze said. He pointed to an NBC News/Wall Street Journal poll last month that found 61 percent of respondents believe laws covering the sale of firearms should be stricter, up from 56 percent the month before amid the more immediate wake of the shooting at an elementary school in Newtown, Conn., that took the lives of 20 students and six workers.
That's encouraging news for the White House, where Obama acknowledged in the days after the shooting that public outrage over the deaths could fade. "I would hope that our memories aren't so short that what we saw in Newtown isn't lingering with us, that we don't remain passionate about it only a month later," Obama said at the time. He had given Biden a month's deadline to recommend steps to reduce gun violence. "I will use all the powers of this office to help advance efforts aimed at preventing more tragedies like this," Obama said then.
Biden seemed like a natural pick to lead the White House effort since as a senator, he authored a crime bill that included an assault weapons ban that became law and lasted a decade. This time, both sides in the gun debate say an assault weapons ban is unlikely to get past Congress. They agree that the trafficking and background check provisions have better chances of becoming law.
Still, Obama pushed Congress in his State of the Union address to take all the measures up. "Each of these proposals deserves a vote in Congress. If you want to vote no, that's your choice. But these proposals deserve a vote," Obama said.
The remark could be seen as an acknowledgement that the measures may not pass ? he was asking lawmakers to vote, not to pass everything. But White House officials have said Obama wants to increase pressure to stop opponents of gun control from keeping the legislation tied up without a vote, a common Senate practice that can bring effective death to legislation.
Forcing a vote on an assault weapons ban that isn't likely to pass also could give political cover to some moderate Democrats to vote for background checks and trafficking bills. Then those senators can tell gun owners back home that even though they supported background checks or anti-trafficking bills, they didn't support anything that would take away a single gun from law-abiding citizens.

NFL free agency 2013: 'Legal tampering' period begins on Friday ...
The NFL's new tampering rules will be tested out starting this evening. The "legal tampering" period, as it's come to be known, begins at 11:00 p.m. (Arrowhead Time) this evening and it's best described as a "soft launch" to free agency.
When: The legal tampering period starts at on Friday night at 11:00 p.m. (Arrowhead Time) and ends at 3:00 p.m. (Arrowhead Time) on Tuesday.
Who: Teams can contact the agents for players but not the players themselves. Players without agents can not negotiate with teams. This applies to unrestricted free agents only. Not restricted free agents or exclusive rights free agents. See the full list of Chiefs free agents here.
What: Teams can not execute contracts with player agents. They can negotiate and set the parameters for a deal, but they can not actually execute the contracts until free agency starts at 3:00 p.m. on Tuesday.
Where: Nowhere. As in, players can not meet with teams until Tuesday. Agents can talk but visits can't happen until Tuesday.
Those are all the big bucket details on the legal tampering period, which kicks off this evening. We'll be talking about the NFL all weekend long, which is exactly what the NFL wants. Prepare for lots of rumors to be coming out as "negotiations" often use the media to further the cause of the agent.

Mystery bug found in Antarctica's Lake Vostok
There is something alive in Lake Vostok, deep beneath the East Antarctic ice sheet, and we don't know what it is. Water samples from the lake contain a bacterium that does not seem to belong to any known bacterial groups ? although whether it truly is a new form of life remains to be proven.
Russian scientists breached Lake Vostok in February 2012, after years of drilling. The lake lies beneath 3.5 kilometres of ice, and has been cut off from the rest of the world since Antarctica froze 14 million years ago.
The Russians' borehole was filled with lubricating kerosene, which contains bacteria ? causing concerns that the lake might be contaminated. But the project seems to have avoided this. When the drill hit the lake, it automatically withdrew in response to the pressure change. Lake water gushed into the borehole, pushing the kerosene up the hole before freezing.
Since last May, Sergey Bulat of the Petersburg Nuclear Physics Institute in Russia and colleagues have been studying the water that froze onto the drill bit. "The samples proved to be very dirty," he says, with lots of kerosene. Preliminary genetic analyses reported last October found bacteria from the drilling fluid, not the lake.
Bulat has now gone back to the DNA samples. Comparing their DNA sequences to a database of known contaminants, he identified short fragments of DNA belonging to 19 different known bacterial species. "All of them proved to be contaminants, or bacteria from human skin," says Bulat.
More unusual
A twentieth species is more unusual. The genetic samples show less than 86 per cent similarity to the known major groups of bacteria. That could mean it belongs to an entirely new division, says Bulat, although he concedes that it could just be a new species.
"This is encouraging, but we don't really know much about it," says David Pearce of the British Antarctic Survey in Cambridge, UK. He says it would have been surprising if there hadn't been life in Lake Vostok, as organisms manage to survive in all manner of extreme environments. More interesting, he says, is what the life in Vostok looks like, and how different it is to everything else on Earth.
Pearce has studied samples from Lake Hodgson, which lies beneath just a few metres of ice in west Antarctica. He says 25 per cent of the genetic sequences he has found do not match anything found in DNA databases. So on its own, having an unusual DNA sequence does not prove that the Vostok bacterium belongs to a new group. There's a long list of systematic tests that will need to be carried out in order to prove that.
The results must also be independently replicated, says Martin Siegert of the University of Bristol, UK, who led an unsuccessful attempt to drill into another Antarctic lake - Ellsworth - last year.
Sediment life
If the bacterium does belong to a new group, it will quickly come under scrutiny. "The next question is, where does it come from?" says Siegert. Researchers think life is most likely in the sediments at the lake bottom, where there is food. But if Bulat's bacterium came from the sediment in Lake Vostok, it must have been sucked up through 700 metres of lake water when the Russian drill head broke through the icy roof above Vostok.
"The only way to find out is to go into the lake itself and do direct sampling," says Siegert. Robots could collect lake water and sediment.
American researchers recently drilled into Lake Whillans, a shallower subglacial lake that is connected to a subglacial network of lakes and rivers, and also found living microbes.

Astronomers find 'lost' supernova
Mar. 7, 2013 ? The star Eta Carinae is ready to blow. 170 years ago, this 100-solar-mass object belched out several suns' worth of gas in an eruption that made it the second-brightest star after Sirius. That was just a precursor to the main event, since it will eventually go supernova.
Supernova explosions of massive stars are common in spiral galaxies like the Milky Way, where new stars are forming all the time. They are almost never seen in elliptical galaxies where star formation has nearly ceased. As a result, astronomers were surprised to find a young-looking supernova in an old galaxy. Supernova PS1-12sk, discovered with the Pan-STARRS telescope on Haleakala, is rare in more ways than one.
"This supernova is one-of-a-kind," said Nathan Sanders of the Harvard-Smithsonian Center for Astrophysics (CfA), lead author of the discovery paper. "And it's definitely in the wrong neighborhood."
Based on the presence of helium and other features, PS1-12sk is classified as a very rare Type Ibn supernova -- only the sixth such example found out of thousands of supernovae. Although the origin of this supernova type is unclear, the most likely cause seems to be the explosion of a massive star that previously ejected massive amounts of helium gas, much like Eta Carinae's Homunculus Nebula.
That origin was supported by the fact that the five previous Type Ibn supernovae were all found in galaxies like the Milky Way that are actively forming stars. (Since massive stars don't live long, they don't stray far from where they are born before exploding.)
PS1-12sk is different. It was found on the outskirts of a bright elliptical galaxy located about 780 million light-years from Earth. The site of the explosion shows no signs of recent star formation, and a supernova from a massive star has never before been seen in a galaxy of this type.
"It could be that we simply got very lucky with this discovery. But luck favors the prepared," said second author Alicia Soderberg of the CfA.
The finding suggests that the host galaxy might be hiding a star factory, allowing it to form massive stars where none were expected. Alternatively, PS1-12sk might have an entirely different origin such as a collision of two white dwarfs, one of which was helium-rich.
"Is this a runaway star from another star formation site? Is it a very local bit of star formation? Is it a different way for such a supernova to occur? None of these seems very likely so we have a real puzzle," said co-author John Tonry (University of Hawaii Institute for Astronomy).
The research has been submitted for publication in The Astrophysical Journal.

Facebook's Sheryl Sandberg urges women to 'lean in'
Gregory Bull / AP
Facebook COO Sheryl Sandberg's new book, "Lean In: Women, Work, and the Will to Lead," will be released on Monday.
By Barbara Ortutay, The Associated Press
NEW YORK - For a book that has yet to be released, Sheryl Sandberg's "Lean In" ? part feminist manifesto, part how-to career guide ? has got a lot of people talking.
In the weeks leading up to the book's release on Monday, pundits and press hounds have been debating its merits. New York Times columnist Maureen Dowd called Sandberg a "PowerPoint Pied Piper in Prada ankle boots," and countless bloggers have suggested that Facebook's chief operating officer is the wrong person to lead a women's movement.?
"Most of the criticism has to do with the position she is coming from," said Susan Yohn, professor and chair of Hofstra University's history department.
Sandberg, 43, hopes that her message of empowerment won't be obscured by the lofty pedestal from which she speaks. But is the multi-millionaire with two Harvard degrees too rich to offer advice? Too successful? Does her blueprint for success ignore the plight of poor and working-class women? Does the book's very premise blame women for not rising to top corporate positions at the same rate as men?
And just how big is her house?
The questions keep coming largely because few people have actually read the book. But in it, Sandberg seems to have foreseen much of the criticism. The book acknowledges that critics might discount her feminist call to action with an easy-for-her-to-say shrug.
"My hope is that my message will be judged on its merits," she writes in the preamble.
Sandberg recognizes that parts of the book are targeted toward women who are in a position to make decisions about their careers. Still, she writes, "we can't avoid this conversation. This issue transcends all of us. The time is long overdue to encourage more women to dream the possible dream and encourage more men to support women in the workforce and in the home."
Published by Alfred A. Knopf Inc., "Lean In: Women, Work, and the Will to Lead" will be launched Thursday with a reception in New York City hosted by Mayor Michael Bloomberg and Arianna Huffington.
It's true that Sandberg is wealthy. She also has a supportive husband. Mark Zuckerberg is her boss. And, yes, her home in Menlo Park, Calif., has 9,000 square feet.
But as a woman in Silicon Valley, Sandberg hasn't exactly had it easy, and her tale shows she's no armchair activist. After all, not many women would march into their boss' office and demand special parking for expectant mothers. But Sandberg did just that when she worked at Google. Company founders Larry Page and Sergey Brin complied.
After Sandberg moved to Facebook in 2008, she became even more outspoken on the issues facing women in corporate America. At a time when other executives, male or female, have largely stayed quiet, Sandberg has delivered speeches on topics such as "Why we have too few women leaders."
And she's no workaholic. In an age of endless work hours, Sandberg is famous for leaving the office at 5:30 to spend time with her family. She does admit, however, to picking up work once her kids have gone to bed.
Of the many inspirational slogans that hang on Facebook's walls, her favorite asks "What would you do if you weren't afraid?" "Lean In" is about pushing past fear.
"Fear is at the root of so many of the barriers that women face," she writes. "Fear of not being liked. Fear of making the wrong choice. Fear of drawing negative attention. Fear of overreaching. Fear of being judged. Fear of failure. And the holy trinity of fear: the fear of being a bad mother/wife/daughter."
Sandberg peppers the book with studies, reports and personal anecdotes to back up her premise ? that for reasons both in and out of their control, there are fewer woman leaders than men in the business world and beyond. For example, the Fortune 500 has only 21 female CEOs. Sandberg is among the 14 percent of women who hold executive officer positions and the 16 percent of women who hold board of director seats, according to Catalyst.org.
For minority women, the numbers are even bleaker. Women of color, she writes, hold just 4 percent of top corporate jobs and 3 percent of board seats.
"A truly equal world would be one where women ran half our countries and companies and men ran half our homes. I believe that this would be a better world," she writes. "The laws of economics and many studies of diversity tell us that if we tapped the entire pool of human resources and talent, our collective performance would improve."
At less than 200 pages, plus a good chunk of footnotes, "Lean In" does not purport to be the end-all solution to inequality. It deals with issues Sandberg sees as in women's control.
"Don't leave before you leave" is one of her catchphrases, aimed at successful women who gradually drop out of the workforce in anticipation of children they may someday bear. "Make your partner a real partner" is another. She says everyone should encourage men to "lean in" at home by being equal partners in parenting and housework.
"Lean In" is, by and large, for women who are looking to climb the corporate ladder (which Sandberg calls a jungle gym), and ideally their male supporters. She hopes it's the start of a conversation. To that end, Sandberg plans to donate all of the proceeds to her newly minted nonprofit, LeanIn.org.
Sandberg's book shares personal details that reveal a fair share of stumbles and lesser-known tidbits. Did you know she was an aerobics instructor in the 1980s ?big hair, silver leotard and all? The book paints a picture of an exceptionally successful woman who admits to lacking confidence at various points in her career.
Sandberg writes about the "ambition gap" between men and women in the workplace ? that while men are expected to be driven, ambition in women can be seen as negative. She writes about parents' gender-based approaches to child rearing that teach girls to be "pretty like mommy" and boys "smart like daddy," as she's seen on baby onesies sold at Gymboree.
And she writes about "feeling like a fraud" ? that insidious notion, felt largely by women but men as well, that success is due not to one's own merit but to some sort of gross oversight or accident.
Sandberg's book comes half a century after Betty Friedan's "The Feminine Mystique," which identified "the problem that has no name" among largely white, suburban housewives who felt unhappy and unfulfilled in their roles at home. Friedan, too, was criticized for focusing on a privileged swath of womankind.
In a recent critical piece on Sandberg's movement, Michael Kazin wrote in the New Republic that, like Friedan, Sandberg, "also seems primarily concerned with the economics of gender. But there's a key difference: Friedan didn't share a view from the corporate boardroom."
Kazin's barbs echo most of the book's pre-release criticism. But some writers have gone further. In a Washington Post op-ed, Melissa Gira Grant dismissed Sandberg's "Lean In" movement as "simply the elite leading the slightly-less-elite, for the sake of Sandberg's bottom line." Dowd wrote that she believes "Sandberg has co-opted the vocabulary and romance of a social movement not to sell a cause, but herself."
In the end, "Lean In" is a call to action to make it easier for women to become leaders. It's a call for women to take space at the table, raise their hands, speak up and step up. It's a personal account of a woman who, through a mix of talent, luck and ambition, but also with plenty of internal and external obstacles along the way, managed to do that.
Feminist icon Gloria Steinem, whom Sandberg thanks in the acknowledgements and cites as inspiration, praises "Lean In" on her Facebook page, saying that it "addresses internalized oppression, opposes external barriers that create it and urges women to support each other to fight both."
She adds that even the book's critics "are making a deep if inadvertent point: Only in women is success viewed as a barrier to giving advice."

NATO chief backs larger Afghan force through 2018
LASHKAR GAH, Afghanistan (AP) ? Afghanistan's president got reassurance Tuesday that NATO intends to backstop his troubled nation's security long beyond 2014, after NATO's chief endorsed keeping Afghanistan's security forces at the current strength for years to come.
NATO Secretary-General Anders Fogh Rasmussen told The Associated Press that keeping the Afghan force larger for longer is more cost effective, and it would be more acceptable to Afghans than foreign soldiers.
He spoke after meeting with Afghan President Hamid Karzai in Kabul on Monday.
"From the political point of view, it is better to give the defense ... an Afghan face, and from an economic point of view, it's less expensive to finance Afghan security forces than to send foreign troops," he said Tuesday as he toured a NATO base in Helmand province.
Fogh Rasmussen was commenting on a proposal favored by the Afghan government ? and debated by NATO ministers in Brussels last month ? to keep 352,000 Afghans in uniform through 2018. NATO is due to turn over security duties to local forces next year and pull out most of its troops. Fogh Rasmussen said most troops in Helmand have already traded combat patrols for advising the Afghans as they do the fighting.
The Afghan army has grown to 184,676 soldiers and the country's police force numbers 146,339 officers, just short of the planned 352,000 total, according to figures shared by NATO this week.
NATO had planned to shrink that combined force to 230,000 next year, but U.S. military and Afghan officials have both suggested keeping the Afghan security forces at their higher "surge" numbers to deal with an expected Taliban onslaught as foreign forces leave.
The "surge" refers to a temporary U.S.-led increase in troops in 2010, aimed at dealing a decisive blow to insurgents, and also to a parallel increase in numbers of Afghan security forces trained and armed by NATO.
The concern for Afghans is that after the NATO drawdown, their green troops could be overrun, and the country plunged back into civil war. Americans worry that the Taliban would use the chaos to regain power, defeating the original purpose of the U.S. military action in 2001.
Cash-strapped NATO members, including the U.S., must figure out who would cover the increased expense for maintaining the Afghan forces at the higher level ? from $4.1 billion annually for the 230,000 troops NATO had planned on, to an estimated $4.8 billion to maintain the surge-level forces.
Fogh Rasmussen says he expects NATO members to make a decision "in a matter of months," likely by summer, as part of their calculations on how many NATO troops to deploy after 2014. U.S. and NATO officials are discussing leaving a residual force of between 8,000 to 12,000 foreign troops to advise and train Afghans after NATO combat operations end.
The White House backs the plan for the Afghan forces, but it must first get through the domestic financial fallout of the automatic spending cuts that kicked in on March 1, dictating mandatory across-the-board reductions in the U.S. federal budget, including defense and foreign aid.
The NATO chief said he and Karzai also discussed signing a long-term security agreement between Afghanistan and NATO, after the U.S. and Afghanistan complete their bilateral security negotiations, possibly by November.
"Once that is concluded, it could serve as a template for a NATO training mission," he said. Fogh Rasmussen added he thought it would be possible to have one agreement covering all nations taking part in the training mission, rather than each nation negotiating with Afghanistan separately. The agreements map out the legal status of foreign forces on Afghan soil.
The NATO chief would not be drawn on Karzai's recent demand that U.S. special operations troops leave Wardak province, following his claims that Afghans linked to U.S. commandos had carried out extrajudicial killings, renditions and torture there. U.S. officials privately denied the charges, while asking Afghan officials to share any evidence they had of such incidents. The officials spoke on condition of anonymity because of the Afghan investigation into the allegations is still ongoing.
Fogh Rasmussen would say only that he expected NATO special operations troops to be a key part of the future mission, especially after his visit with European special forces trainers and their Afghan counterparts at the base in Lashkar Gah.
"No doubt that Afghan special operations forces will be the bedrock of Afghan security in the future, so obviously they will also need our continued training, advice and assistance," he said.

Not PC: Cognitive child abuse in the maths classroom
Leighton Smith has been talking about this on his show, this morning:
New Zealand's foremost mathematician has spoken out against the way maths is taught in schools, saying children need to know basic arithmetic before they try to start problem solving.
??? Sir Vaughan Jones, winner of the Fields Medal - the maths equivalent of the Nobel Prize - told the Weekend Herald that children had to do "lots and lots of exercises" to build up familiarity and confidence before they moved on to more advanced concepts.
??? His comments follow those of Education Minister Hekia Parata, who said last weekend that she was "extremely concerned" by results from an international survey of Year 5 children in December, which showed half could not add 218 and 191.
This might be the first education minister to be concerned by basic educational failure.
"People are trying to teach kids broad concepts too early [says Jones] when, in fact, the best way to learn is the complete opposite.
??? "It is really important that kids learn how to multiply and add, to the point where they are certain they will get the right answer if they do the steps right. Then, and not before, they start to see more aspects of the structure. It is a slow process built on understanding each step?
??? He said that since the 1980s New Zealand had slavishly followed California in abandoning perfectly functional maths methods built up over thousands of years.
And so we have.? As Sandra Stotsky explains in an article it?s worth reading thoroughly, what's been abandoned, both here and in the States, is any objectivity at all, or even genuine education. Even of mathematics. Because what?s become more important in the factory schools both here and there is not education of children, but their socialisation:
??? Assessment experts, technology salesmen, and math educators?the professors, usually with education degrees, who teach prospective teachers of math from K?12?dominate the development of the content of school curricula and determine the pedagogy used, into which they?ve brought theories lacking any evidence of success and that emphasize political and social ends, not mastery of mathematics. . .
??? The underlying goals of [education]?never made clear to the general public?were social, not academic. Some of the [theorists], for example, sought to make mathematics ?accessible? to low-achieving students, yet meant by this not, say, recruiting more talented undergraduates into teaching but instead the employment of trendy, though empirically unsupported, pedagogical and organizational methods that essentially dumb down math content.
In striving for ?social? standards instead of objective academic standards, the professors are still following the pedagogical trajectory mapped out by progressive educator John Dewey, who saw education primarily as ?socialisation.? ?Education, in its broadest sense,? said Dewey, ?is the means of this social continuity of life.? What this means, notes Stephen Hicks, is that ?education is not about equipping individuals for life. It does educate individuals, but its purpose is social continuity.?
Think about that, and you?ll understand why teachers, teacher unions, and the academics who teach teachers are undisturbed by a widespread failure to add 218 and 191.
[These] educational trends . . .? have a long pedigree. During the 1970s and 1980s, educators in reading, English, and history argued that the traditional curriculum needed to be more ?engaging? and ?relevant? to an increasingly alienated and unmotivated?or so it was claimed?student body. Some influential educators sought to dismiss the traditional curriculum altogether, viewing it as a white, Christian, heterosexual-male product that unjustly valorized rational, abstract, and categorical thinking over the associative, experience-based, and emotion-laden thinking supposedly more congenial to females and certain minorities.
??? Those trying to overthrow the traditional curriculum found mathematics a hard nut to crack, however, because of the sequential nature of its content through the grades and its relationship to high school chemistry and physics. Nevertheless, education faculty eventually figured out how to reimagine the mathematics curriculum, too, so that it could march under the banner of social justice. As Alan Schoenfeld . . . put it, ?the traditional curriculum was a vehicle for . . . the perpetuation of privilege.? The new approach would change all that.
??? Two theories lie behind the educators? new approach to math teaching: ?cultural-historical activity theory? and ?constructivism.? According to cultural-historical activity theory, schooling as it exists today reinforces an illegitimate social order.
??? Typical of this mindset is Brian Greer. . .? According to Greer, the proper approach to teaching math ?now questions whether mathematics as a school subject should continue to be dominated by mathematics as an academic discipline or should reflect more fully the range of mathematical activities in which humans engage.? The primary role of math teachers, constructivists say in turn, shouldn?t be to explain or otherwise try to ?transfer? their mathematical knowledge to students; that would be ineffective. Instead, they must help the students construct their own understanding of mathematics and find their own math solutions.?
Yep, sounds like bullshit doesn?t it.? Little Johnny ?constructs? his own knowledge; mathematics is about socialisation not education; algebra is more amenable to emotion than to reason; and education is a white, hegemonic, patriarchal practice ? at least it is according to alleged educators like Schoenfeld, Greer and his colleagues.?
No wonder Little Johnny from America came ?25th out of 30 countries in mathematics achievement on the 2006 Programme for International Student Assessment (PISA), which claims to assess application of the mathematical knowledge and skills needed in adult life through problem-solving test items.?
Brad Thompson calls this whole approach Cognitive Child Abuse in Our Math Classrooms:
America's children are flunking math. In 1996 American high school seniors finished close to the bottom on an international mathematics test. At the end of last year, American eighth-graders ranked below those of Malaysia, Bulgaria, and Latvia.
??? As educators scramble to explain America's math meltdown ? few are willing to look at the fundamental cause: the new, ?whole-math? method for teaching.
??? ?Inspired by a strain of progressive-education theory called ?constructivism,? whole-math proponents claim that all knowledge--including mathematical knowledge--is arbitrarily constructed. They reject the idea that there are objectively demonstrable right and wrong answers, and that, consequently, there are basic skills that students must be taught. Instead, the advocates of whole math believe that each student should invent his or her own math ?strategies? by using a ?guess-and-check? approach. They create an inability to think beyond immediate concretes.?
The results in their respective fields were the same for ?whole math? as they have been for ?whole language?: whole generations of children emerging from school functionally illiterate and almost wholly innumerate.
This is cognitive child abuse. Whole-math defenders are shrinking the cognitive capacities of their students to those of infants or even animals.
??? Is it any wonder that most college freshman take remedial math courses, that American universities award more than half of their mathematics Ph.D.s to foreign nationals, that for-profit math remediation companies are booming, and that 200 of the nation's leading mathematicians and scientists signed a public letter denouncing whole math? . . .
??? The controversy surrounding whole math is not simply about how children are taught to deal with numbers. If we undermine the capacity of our children to learn mathematics, we undercut their ability to think. More and more, our schools are turning out students whose capacity to reason has atrophied. . .
??? Now imagine flying on a plane designed by aeronautical engineers who have been trained to concoct their own math schemes and to use a ?guess-and-check? method. . . .
?? Today's "math wars," like the controversy over how to teach reading, are at root philosophic battles that will have enormous implications for the future of America. If the advocates of whole math are allowed to win, they will be taking us a huge step away from the values of reason and science that once made America [and the western world since the Enlightenment] great.?

6 Simple Ways to Safeguard Your Vision | Care2 Healthy Living
The number of aging Americans with significant age-related vision loss is expected to double by 2030, according to the American Foundation for the Blind.
Indeed, multiple studies indicate that the vast majority of people who are legally blind (having a visual acuity of 20/200 or less, or a visual filed that is limited to 20 degrees or less) are elderly individuals suffering from the most-common age-related eye diseases including: glaucoma, cataracts, age-related macular degeneration and diabetic retinopathy.
Even the eyes of younger baby boomers aren?t immune from the ravages of aging. People between the ages of 45 and 64 years old were twice as likely to experience vision loss, when compared to younger populations, according to the 2011 National Health Interview Survey.
The good news is that there are ways to safeguard your eyes against the issues of aging and prevent the progression of certain vision-robbing ailments.
Here are 6 simple vision protection tips from the experts:
Stick to an exercise regimen: Engaging in a regular workout program provides countless health benefits?from cardiovascular to cognitive. Physical activity can also help keep your eyes healthy. By breaking a sweat three or more times each week, adults middle-aged and older could experience up to a 70 percent reduction in risk for developing age-related macular degeneration, according to a 2006 University of Wisconsin study.
Up your antioxidants: Food plays an important role in preventing everything from cataracts to age-related macular degeneration. According to the American Optometric Association (AOA), vitamins C and E, lutein, zeaxanthin, zinc and essential fatty acids are all key nutrients for maintaining good eyesight as you age. Vitamins C and E?found in abundance in green, leafy vegetables (spinach, kale), berries, citrus fruits, nuts and sweet potatoes?help guard against damage from free radicals and can lower your chances of developing cataracts. The lutein and zeaxanthin in green, leafy vegetables and eggs may reduce the risk of multiple age-related eye diseases. Fatty acids (especially the omega-3s in walnuts, salmon and soybeans) and zinc (oysters, dark chocolate and peanuts) are important for maintaining the structural health and integrity of the tissues in your eyes.
15 Ways to Eat Sweet Potatoes
Rock some shades: The damaging effects of ultraviolet (UV) radiation aren?t limited to your skin. If left unprotected, UVA and UVB rays can harm your eyes and contribute to the formation of cataracts. When you?re out in the sun (even in the wintertime), it?s important to wear sunglasses and a wide-brimmed hat for full protection from harmful radiation. Opt for lenses that offer 100 percent UV protection and be aware that this is not a feature offered by all types of sunglasses. Polarized, mirror-coated, blue-blocking and photochromatic lenses have different features that can make it easier to see in bright sunlight, but they don?t all automatically block UV rays.

Getting around the uncertainty principle: Physicists make first direct measurements of polarization states of light
Mar. 3, 2013 ? Researchers at the University of Rochester and the University of Ottawa have applied a recently developed technique to directly measure for the first time the polarization states of light. Their work both overcomes some important challenges of Heisenberg's famous Uncertainty Principle and also is applicable to qubits, the building blocks of quantum information theory.
They report their results in a paper published this week in Nature Photonics.
The direct measurement technique was first developed in 2011 by scientists at the National Research Council, Canada, to measure the wavefunction -- a way of determining the state of a quantum system.
Such direct measurements of the wavefunction had long seemed impossible because of a key tenet of the uncertainty principle -- the idea that certain properties of a quantum system could be known only poorly if certain other related properties were known with precision. The ability to make these measurements directly challenges the idea that full understanding of a quantum system could never come from direct observation.
The Rochester/Ottawa researchers, led by Robert Boyd, who has appointments at both universities, measured the polarization states of light -- the directions in which the electric and magnetic fields of the light oscillate. Their key result, like that of the team that pioneered direct measurement, is that it is possible to measure key related variables, known as "conjugate" variables, of a quantum particle or state directly. The polarization states of light can be used to encode information, which is why they can be the basis of qubits in quantum information applications.
"The ability to perform direct measurement of the quantum wavefunction has important future implications for quantum information science," explained Boyd, Canada Excellence Research Chair in Quantum Nonlinear Optics at the University of Ottawa and Professor of Optics and Physics at the University of Rochester. "Ongoing work in our group involves applying this technique to other systems, for example, measuring the form of a "mixed" (as opposed to a pure) quantum state."
Previously, a technique called quantum tomography has allowed researchers to measure the information contained in these quantum states, but only indirectly. Quantum tomography requires intensive post-processing of the data, and this is a time-consuming process that is not required in the direct measurement technique. Thus, in principle, the new technique provides the same information as quantum tomography but in significantly less time.
"The key to characterizing any quantum system is gathering information about conjugate variables," said co-author Jonathan Leach, who is now a lecturer at Heriot-Watt University, UK. "The reason it wasn't thought possible to measure two conjugate variables directly was because measuring one would destroy the wavefunction before the other one could be measured."
The direct measurement technique employs a "trick" to measure the first property in such a way that the system is not disturbed significantly and information about the second property can still be obtained. This careful measurement relies on the "weak measurement" of the first property followed by a "strong measurement" of the second property.
First described 25 years ago, weak measurement requires that the coupling between the system and what is used to measure it be, as its name suggests, "weak," which means that the system is barely disturbed in the measurement process. The downside of this type of measurement is that a single measurement only provides a small amount of information, and to get an accurate readout, the process has to be repeated multiple times and the average taken.
Boyd and his colleagues used the position and momentum of the light as the indicator of the polarization state. To couple the polarization to the spatial degree of freedom they used birefringent crystals: when light goes through such a crystal, there is a spatial separation introduced for different polarizations. For example, if light is made of a combination of horizontally and vertically polarized component, the positions of the individual components will spread out when it goes through the crystal according to its polarization. The thickness of the crystal can control the strength of the measurement, weak or strong, and determine the degree of separation, correspondingly small or large.
In this experiment, Boyd and his colleagues passed polarized light through two crystals of differing thicknesses: the first, a very thin crystal that "weakly" measures the horizontal and vertical polarization state; the second, a much thicker crystal that "strongly" measures the diagonal and anti-diagonal polarization state. As the first measurement was performed weakly, the system is not significantly disturbed, and therefore, information gained from the second measurement was still valid. This process is repeated several times to build up accurate statistics. Putting all of this together gives a full, direct characterization of the polarization states of the light.

Knicks' Anthony injures knee
CLEVELAND (AP) ? Knicks All-Star forward Carmelo Anthony injured his right knee against the Cavaliers and will not return.
With New York trailing by 22 and playing poorly, Anthony stumbled near midcourt after catching a pass and fell awkwardly to the floor. He got up, and appearing more embarrassed than hurt, immediately headed to the locker room with a slight limp.
Just before halftime, the Knicks announced that Anthony would not be back but offered no other details about his injury.
Anthony, who entered the game tied with Oklahoma City's Kevin Durant for the NBA's top scoring average (28.6 points), had six points on just 1 of 5 shooting and three turnovers before going out.
Anthony scored 32 points Sunday, when the Knicks blew a 16-point lead and lost to Miami.

Apple's iWatch Could Be Super Profitable For Apple - Business Insider
Screenshot from Objectified
Apple designer Jony Ive
?
Apple's iWatch, which is reportedly coming this year, could kill three birds with one stone for Apple.1. It gives Apple an experimental entry in the wearable computing market which is said to be the next big thing
2. If done well it would kill the Apple-can't-innovate-without-Steve Jobs meme
3. It could be super profitable.
Let's tackle the third one. Bloomberg, citing a Citigroup report, says the global watch industry will do $60 billion in sales this year, with average gross margins of 60 percent.
Apple's iWatch, should it be released, will probably not fit neatly into the watch industry, so these comparisons are probably moot. (The margins on a $54,000 Audemars Piguet watch are probably pretty high, but unrelated to a mini-computer on your wrist.)
However, that doesn't mean we can't take a shot at trying to figure out how much money Apple could make on an iWatch.
In 2010, iSuppli estimated Apple's cost of goods plus manufacturing bill was $45.10 for an iPod Nano. The iPod Nano was the little square iPod with a touch screen. It actually wound up being used as a watch by a lot of people, and perhaps was a preview of an iWatch at Apple.
Apple sold the 8 GB iPod Nano for $149 and the 16 GB iPod Nano for $179. It's always an imperfect science relying on iSuppli for costs since Apple buys in bulk and hammers out special deals. However, using iSuppli as a rough estimate suggests the iPod Nano was super profitable.We don't know what Apple is planning for the iWatch, but if we use this rough estimate, it's not hard to imagine the margins on an iWatch being quite healthy.
One of the chief concerns for Apple, from an investors' perspective, is the risk of margin collapse. If Apple could get margin on the iWatch like it did on the iPod Nano it would help the company's overall margins significantly.
Compare this to a TV, which many people have been anticipating. As Bloomberg points out, the margin on a TV is much smaller, and the market is much more competitive.
Going with an iWatch could be a more lucrative, innovative move from Apple.
And watch below for everything you need to know about the rumored "iWatch":

Save Time And Money With This Great Home Improvement Advice ...
TIP! Before you attempt to repaint a wall with glossy paint on it, use a good primer. This helps the paint adhere to the wall better and prevents the new paint from peeling.
People improve their homes for many reasons. Some people are simply tired of their home?s current look. Some just want to boost property values. And others simply love home improvements and find working on their home fun and relaxing. Whatever the reason you are doing it, here are some great home improvement tips.
TIP! Keep in mind the type of crime that area has seen and allow yourself to view the positive and negative ideas of having a home security system in place. If you do not live in the home and the neighborhood is dangerous, you may want to have an alarm.
When the budget is flexible, use natural materials when doing home improvement interior projects. Natural building products like wood, stone and ceramic are almost always much better to their synthetic counterparts. Not only are they more attractive but they are also more durable. Choosing natural materials over synthetics can prove more cost effective as synthetics will need replacement more frequently.
TIP! Take into consideration how long each home improvement project lasts. For example, you can expect a new chimney to be usable for a lifetime of at least 100 years.
Whether you live in the suburbs or the chicest gated community, chandeliers are definitely ?in?. With a minimal investment, you can acquire a stunning focal point for any room in your home. Total wattage of 200-400 adds extra sparkle and shine.
TIP! Does your floor need some work? If you have the ambition, you can remove your floor and install adhesive wood flooring. Some people believe this sort of flooring is cheap; however, it?s nice if done properly.
If you have sharp furniture, you should put down some padding, which will keep children safe and make your home look nicer. There are prefabricated corner covers available for purchase; however, foam tape can also achieve the desired effect. Another way to prevent your child from getting hurt is to use tape on any loose wiring.
TIP! When shopping around for different contractors, try to avoid instantly jumping on the company that offers you the lowest estimate. No price can replace the need to thoroughly research any company you are considering for your home improvement needs.
When painting your house or just a portion of it, calculate how much paint you?re going to need. Don?t guess about the costs because that can end up costing you big time. The time you invest on properly assessing the job will be time and money that you save in the end.
TIP! Radiant heating is inexpensive and easy once you know the correct procedures. Look into radiant heat equipment, especially if you want to replace your flooring anyway.
We all tackle some sort of home improvement eventually. There may be different motivations, but every homeowner thinks about home improvement. To increase the appeal of your home or to give it more value, use the advice in the article above to get started today.
