Knicks overcome Curry's 54 to beat Warriors

NEW YORK (AP) — Stephen Curry rose for another jumper, and by then even the Knicks probably figured it would go in.

Curry had hardly missed in a scintillating second half of the NBA's most electric performance this season, the crowd cheering even before the ball left his hands.

This time, Raymond Felton jumped with him, making the play New York needed to finally withstand Curry.

Felton's blocked shot led to J.R. Smith's tiebreaking basket with 1:10 left, and the Knicks overcame Curry's NBA season-high 54 points to beat the Golden State Warriors 109-105 on Wednesday night.

Curry was 18 of 28 from the field, finishing one shy of the NBA record with 11 3-pointers in 13 attempts, in a performance that had the crowd hanging on his every shot. But the Knicks and Felton finally stopped him with 1:28 to play and the score tied at 105.

"My main thing is to keep playing. Like I said, once a guy gets it going like that, there's nothing I can really do. I've still got to stay in my mindset, still play my game, and I was still able to come up with some big plays at the end," Felton said. "We all came up with some big plays to get that win."

Carmelo Anthony followed Smith's basket with another one and the Knicks hung on to spoil former Knicks star and Warriors coach Mark Jackson's homecoming.

Anthony finished with 35 points and Smith had 26.

"We made the defensive stops we needed to make down the stretch," Knicks coach Mike Woodson said.

Playing all 48 minutes, Curry finished with seven assists and six rebounds while passing his previous career best of 42 points, and Kevin Durant's 52-point performance that had been the best in the NBA this season.

"I felt good all night. Obviously played the whole game, so was just trying to keep my legs underneath me on the offensive end, and you know, just stick to the game on the defensive end," Curry said. "Once I started seeing that 3-ball go down in transition, all sorts of spots on the floor, I knew it was going to be a good night."

But he had little help without All-Star forward David Lee, who was suspended one game for his role in an altercation Tuesday night in Indiana.

Tyson Chandler had 16 points and a career-best 28 rebounds for the Knicks, who won their second straight after a season-high, four-game losing streak. Amare Stoudemire had 14 points and Anthony added eight assists on the day the Knicks learned they could be without reserve forward Rasheed Wallace for the rest of the season because he needs surgery to repair a broken bone in his left foot.

Strutting all over the court whenever one of his 3s swished easily through the nets, Curry easily blew past the 38 points he scored Tuesday in Indiana, which had been his best of the season. That was spoiled when he was fined $35,000 for his role in the skirmish, which was essentially getting thrown to the ground by Roy Hibbert when he tried to intervene.

This performance — the most points by an NBA player in a loss since Kobe Bryant had 58 in a loss to Charlotte on Dec. 29, 2006 — was spoiled along with Jackson's trip back to his old home because of a few mistakes down the stretch.

Curry threw away a pass on the break with 3:13 left, and Jarrett Jack was called for a travel following Smith's go-ahead basket.

Plus, Klay Thompson finished 3 of 13 from the field, missing two straight from deep in the final minute.

Jackson, who grew up in Brooklyn and starred at St. John's before being drafted by the Knicks in 1987, didn't get a chance to coach here last season as an NBA rookie on the bench because of the lockout. He brought his wife, Desiree, to a road game for the first time this season, had his mother in the stands, and got a chance to see people he remembered from playing here years earlier.

He said he hadn't gotten to look ahead much to the game because of the schedule, but clearly enjoyed being back in Madison Square Garden once the day did arrive.

"This is a special place and it was part of my dreams as a kid," he said.

His night turned into Curry's, fans cheering even before the ball left his hand in the second half.

"We were short-handed and we needed a performance like that to have a chance," Jackson said. "He put on a clinic. Knocked down shots. Made plays. Carried us. Led us in rebounding. He did it all. I've seen a lot of great performances in this building and his goes up there. I've seen a lot. I've seen a lot, but that shooting performance was a thing of beauty."

The Knicks, who hadn't played since Sunday, looked ready to blow the Warriors out early, taking a 25-11 lead that the Warriors trimmed to 27-18 at the end of the first period before surging ahead behind Curry.

He scored 12 straight Golden State points, cutting it to 35-34 with his third 3-pointer of the second quarter. He followed Richard Jefferson's 3 with another one, giving the Warriors a 40-37 advantage. The Knicks recovered and went back ahead by nine late in the period before Curry answered with six consecutive points, and New York's lead was 58-55 at the break.

"He's a special young player with a very unique talent," Chandler said. "We ran everything at him. He just got hot. There was some shots that he couldn't have seen the rim."

Curry's drive gave the Warriors a two-point lead three minutes into the third quarter, but he didn't score again until hitting a turnaround 3 from 27 feet with 5 seconds left in the period, giving him 38 points again and cutting New York's lead to 84-81.

Already without Andrew Bogut because of a back injury, the Warriors had little size without Lee. Their lineup at one point in the second quarter had nobody taller than 6-foot-9 and Chandler simply climbed over them all night.

He came in leading the league with 4.4 offensive rebounds per game, and grabbed 13 boards in the first quarter alone.

Notes: Chandler was also the last NBA player to grab 13 rebounds in one quarter, hauling in 14 in the third quarter for Dallas on Dec. 1, 2010. ... Wallace, who hasn't played since December, will have surgery this week and the expected recovery time is eight weeks. Woodson said he didn't plan to waive the 38-year-old forward and create a roster spot, instead hoping he could be able to play in the postseason. ... Kenyon Martin, signed last week in part because of the uncertainty around Wallace, made his Knicks debut and was scoreless in 5 first-half minutes.

Taiwan ebullient over Ang Lee's Oscar

Label: Lifestyle

STORY HIGHLIGHTS

Ang Lee's name beamed on building in Taiwan after Oscar win

Lee, born in Taiwan, won award for best director for "Life of Pi"

Lee's win created excitement in Taiwan and China, both claimed him as their own

Ryan: "In some ways it feels like 'Linsanity' all over again"

Editor's note: Andrew Ryan is a host and producer at Radio Taiwan International, a government-owned station that broadcasts in several languages and countries. He first came to Taiwan in 1996 as a Fulbright scholar and has spent the last 16 years as a translator and observer of politics and culture.

Taipei (CNN) -- It's not every territory in the world that puts an Oscar-winning director's name up in lights on a towering building. But that's just the sort of thing that happens in Taiwan -- and it did on Monday night after Ang Lee picked up his second "Best Director" Oscar, this time for "Life of Pi."

The moment wasn't just celebrated in grand statements, but in small scenes played out in front of televisions across Taiwan when his name was announced.

I was at a TV station in Taipei that was broadcasting live coverage of the Oscars, working with a team of translators that was creating the subtitles for the rebroadcast. When Lee's name was announced the office erupted in applause. Down the hallway, more cheering could be heard.

READ: Oscar winners: Analysis of who won

I couldn't help but think back to the Athens Games in 2004, when Chen Shih-hsin won Taiwan's first ever Olympic gold medal (under the team name "Chinese Taipei"). Even veteran news anchors shed tears when the young taekwondo star defeated her Cuban rival.

It would be reductive to suggest that these displays of patriotism are simply the response of a small country that just doesn't crank out that many Oscar winners or Olympic golds. It also speaks of a place that has been largely marginalized in the international community.

Today, Taiwan has just 23 official diplomatic allies -- mostly other marginalized nations, in Central America and Africa. That's because China still sees Taiwan as part of its territory more than 60 years after the Chinese Nationalists retreated to the island at the end of a Civil War against the Communists. The Nationalists -- or Kuomintang -- are now the ruling party in a democratic Taiwan, which is officially called the Republic of China (ROC) -- not to be confused with the People's Republic of China on the Mainland.

Having lost its seat at the United Nations to the PRC in 1971, the ROC found itself with a diminished voice in the international community. It turned to manufacturing and technology in the 1980s, spurring on what is now referred to as an "economic miracle." Today, with its economy struggling to move past the global economic downturn, Taiwan has added the arts, sports, and even baking to its repertoire.

READ: Oscars 2013: Hollywood gets political

What's striking about Lee's win is that it's not just people in Taiwan who were quick to claim him as one of their own. In China, the state-run Xinhua news agency referred to him as "Chinese-American." While Taiwanese media latched onto the portion of Lee's acceptance speech when he thanked Taiwan and the central city of Taichung where much of the movie was filmed, Xinhua's main story included Lee's line of thanks to the 3,000 people who worked on the film for "believing this story and sharing this incredible journey with me."

In some ways it feels like "Linsanity" all over again, when Taiwan and China both claimed basketball star Jeremy Lin as their own, leaving the international media struggling to chart the dangerous waters of identity politics to correctly describe him.

VIEW: Photos from the red carpet

A very small voice at the fringe of the discussion wonders why it's important for people to know that Lin's paternal grandmother lives in Taiwan and referred to him as "a real Taiwanese," or that Lee grew up in Tainan and still loves to visit his favorite noodle shop there. Others in Taiwan question why a nation's confidence should be based on its success in the international community.

When Ang Lee's name was announced, the office erupted in applause. Down the hallway, more cheering could be heard.
Andrew Ryan

With China looming to the north, now the world's second biggest economy and wielding an influence that's verging on "superpower" status, the metaphor of Jonah and the whale comes to mind. The Taiwanese electorate is sharply divided on how it feels about the way ties with China have warmed ever since President Ma Ying-jeou first took office in 2008. The benefits are obvious, considering China is Taiwan's largest trade partner, but some worry that it could lead to a loss in autonomy.

INTERACTIVE: Oscars by numbers

The Ma administration has been mindful of the nationalistic rhetoric of the opposition, and although the president was born in Hong Kong, he has referred to himself in the past as "Taiwanese as well as Chinese." Ma was also quick to congratulate Lee following the Oscars, and to urge others to follow in the director's footsteps and "work hard at promoting Taiwan to the world."

Lee is just one name on a growing list of national heroes that both the government and the private sector have celebrated in recent years for putting Taiwan on the map: people like fashion designer Jason Wu, who moved to Canada from Taiwan and has created garments for U.S. First Lady Michelle Obama; master baker Wu Pao-chun, who beat the French patissiers at their own competition -- Les Masters de la Boulangerie in 2010; Yani Tseng, the world's number one female golfer; and even the humble vegetable seller-turned-philanthropist Chen Shu-chu, who was selected by Time Magazine as one of its heroes of 2010.

So what are people saying when they embrace these heroes as Taiwanese? They are saying "Taiwan may be small and diplomatically isolated, but it deserves to have a voice in the international community." While Lee may not speak about politics and no longer creates movies about Taiwan, he does have a voice and people do listen. And that's worth spreading in lights across the world's second-tallest building.

Warning about student ‘money mules’

Label: Business

25 February 2013 Last updated at 19:03 ET

By Simon Gompertz Personal finance correspondent, BBC News

Fraud experts are warning that hundreds of thousands of people are in danger of being duped into laundering money for fraudsters.

They are being recruited as unwitting “money mules” who allow their own bank accounts to be used to disguise the proceeds of crime.

The study was carried out by Financial Fraud Action, which tackles fraud on behalf of banks.

It said that students and jobseekers could be especially vulnerable.

Some 19% of students who had been approached had agreed to become money mules.

“It’s a very serious problem,” warns DCI Dave Carter, an investigator from Financial Fraud Action.

“Almost every single criminal transaction that goes on depends on money mules, to turn the money from crime into something the criminals can spend themselves.”

How it works

Continue reading the main story

It just makes you feel sick. I don’t want it to happen again.”

End Quote Kayleigh Rance job-seeker

The fraudsters contact likely targets by sending out mass emails offering employment, or after sifting through CVs posted by job seekers on employment websites.

Then they offer jobs as “money transfer agents”, “payment processing agents” or “administration assistants” for salaries of hundreds of pounds a week.

It looks like a proper job offer, but the real purpose is to channel cash from criminal activity through a person’s own bank account, making them the fraudster’s money mule.

Kayleigh Rance has been hunting for work for a year. She was taken in and even signed a contract. Then, luckily, she pulled out.

“It just makes you feel a bit sick,” she complains, “I feel like I’ve got to go through all the websites now and take my CV off because I don’t want it to happen again.”

The dirty cash comes from credit card fraud, money stolen from bank accounts and other rip-offs.

Paying it into the money mule’s account disguises where it comes from. The mule transfers it to an account in an overseas bank, controlled by the fraudster. It is classic money laundering.

Some money mules are paid by a straightforward cut of the cash being handled. A typical share would be 8%.

Campaign

The first mules tended to be new entrants to the UK, processing funds generated by crime within their own communities in London and other major cities.

But the power of the internet has allowed the perpetrators to start targeting other groups, including students desperate to earn some extra cash.

Financial Fraud Action commissioned ICM to question 2,000 adults along with separate groups exclusively made up of students, jobseekers and new entrants to the UK.

Around 15% had received the suspect job offers. Overall 6% of those who had been approached accepted the offers, rising to 13% of the unemployed, 19% of students and 20% of new entrants.

Crimestoppers is running a campaign in universities across the UK to warn students not to be fooled into becoming involved, telling them: “Don’t be a mule!”.

‘Colossal risk’

Megan Owen, who is studying criminology, volunteered to help at one recent event in Birmingham City University.

“Lots of students we approached said they’d been affected or their friends had been affected,” she said.

Extrapolating from its survey, Financial Fraud Action concludes that 380,000 people could have become unwitting money mules.

The figure is a stab in the dark, but it is clear that the problem is becoming worse and that few of those who become involved understand the risks they are running.

Their bank accounts could be frozen. If prosecuted, they could be sent to prison for up to 10 years.

“It’s a colossal risk,” warns DCI Carter. “In fact you are taking almost all the risk on behalf of the criminal. That’s why they ask – the money mules are the ones most likely to be caught.”

Community college grads out-earn bachelor’s degree holders

Label: World

Berevan Omer graduated on a Friday in February with an associate’s degree from Nashville State Community College and started work the following Monday as a computer-networking engineer at a local television station, making about $ 50,000 a year.

That’s 15% higher than the average starting salary for graduates — not only from community colleges, but for bachelor’s degree holders from four-year universities.

“I have a buddy who got a four-year bachelor’s degree in accounting who’s making $ 10 an hour,” Omer says. “I’m making two and a-half times more than he is.”

Omer, who is 24, is one of many newly minted graduates of community colleges defying history and stereotypes by proving that a bachelor’s degree is not, as widely believed, the only ticket to a middle-class income.

Nearly 30% of Americans with associate’s degrees now make more than those with bachelor’s degrees, according to Georgetown University’s Center on Education and the Workforce. In fact, other recent research in several states shows that, on average, community college graduates right out of school make more than graduates of four-year universities.

The average wage for graduates of community colleges in Tennessee, for instance, is $ 38,948 — more than $ 1,300 higher than the average salaries for graduates of the state’s four-year institutions.

In Virginia, recent graduates of occupational and technical degree programs at its community colleges make an average of $ 40,000. That’s almost $ 2,500 more than recent bachelor’s degree recipients.

“There is that perception that the bachelor’s degree is the default, and, quite frankly, before we started this work showing the value of a technical associate’s degree, I would have said that, too,” says Mark Schneider, vice president of the American Institutes for Research, which helped collect the earning numbers for some states.

And while by mid-career, many bachelor’s degree recipients have caught up in earnings to community college grads, “the other factor that has to be taken into account is that getting a four-year degree can be much more expensive than getting a two-year degree,” Schneider says.

A two-year community college degree, at present full rates, costs about $ 6,262, according to the College Board. A bachelor’s degree from a four-year, private residential university goes for $ 158,072.

The increase in wages for community college grads is being driven by a high demand for people with so-called “middle-skills” that often require no more than an associate’s degree, such as lab technicians, teachers in early childhood programs, computer engineers, draftsmen, radiation therapists, paralegals, and machinists.

With a two-year community college degree, air traffic controllers can make $ 113,547, radiation therapists $ 76,627, dental hygienists $ 70,408, nuclear medicine technologists $ 69,638, nuclear technicians $ 68,037, registered nurses $ 65,853, and fashion designers $ 63,170, CareerBuilder.com reported in January.

“You come out with skills that people want immediately and not just theory,” Omer says.

The Georgetown center estimates that 29 million jobs paying middle class wages today require only an associate’s, and not a bachelor’s, degree.

“I would not suggest anyone look down their nose at the associate’s degree,” says Jeff Strohl, director of research at the Georgetown center.

“People see those programs as tracking into something that’s dead end,” Strohl says. “It’s very clear that that perception does not hold up.”

The bad news is that not enough associate’s degree holders are being produced.

Only 10% of American workers have the sub-baccalaureate degrees needed for middle-skills jobs, compared with 24% of Canadians and 19% of Japanese, the Organization for Economic Cooperation and Development reports.

Over the last 20 years, the number of graduates with associate’s degrees in the United States has increased by barely 3%. And while the Obama administration has pushed community colleges to increase their numbers, enrollment at these schools fell 3.1% this year, the National Student Clearinghouse Research Center reports. Graduation rates also remain abysmally low.

Meanwhile, many people with bachelor’s degrees are working in fields other than the ones in which they majored, according to a new report by the Center for College Affordability and Productivity.

“We have a lot of bartenders and taxi drivers with bachelor’s degrees,” says Christopher Denhart, one of the report’s coauthors.

Still, the salary advantage for associate’s degree holders narrows over time, as bachelor’s degree recipients eventually catch up, says Schneider.

Although these figures vary widely by profession, associate’s degree recipients, on average, end up making about $ 500,000 more over their careers than people with only high school diplomas, but $ 500,000 less than people with bachelor’s degrees, the Georgetown center calculates.

As for Omer, he’s already working toward a bachelor’s degree.

“Down the road a little further, I may want to become a director or a manager,” he says. “A bachelor’s degree will get me to that point.”

This story was produced by The Hechinger Report, a nonprofit, nonpartisan education-news outlet based at Teachers College, Columbia University. It’s one of a series of reports about workforce development and higher education.

Minnesota takes down No. 1 Indiana 77-73

Label: Technology

MINNEAPOLIS (AP) — Retaining that No. 1 national ranking has been elusive throughout this wild season in college basketball, and Indiana was the latest to lose at the top — again.

Most important and maybe more challenging for the Hoosiers, however, is holding on to first place in the tough-as-ever Big Ten.

Trevor Mbakwe had 21 points on 8-for-10 shooting and 12 rebounds to help Minnesota take down top-ranked Indiana 77-73 on Tuesday night, the seventh time the No. 1 team in the Associated Press poll has lost this season. Three of those losses were by the Hoosiers, who were No. 1 when they fell to Butler and Wisconsin earlier this season. All three opponents were unranked at the time.

Indiana (24-4, 12-3) has held the No. 1 ranking for 10 of the 17 polls by the AP this season, including the last four, and that will likely change next week. But fending off Michigan, Michigan State and Wisconsin is what's on the minds of the Hoosiers, who'll take a one-game lead in the conference race into Saturday's game against Iowa.

"Winning the Big Ten was going to be tough whether we won today or lost," said star guard Victor Oladipo, who had 16 points. "We knew it was going to be tough from the jump. Now it's even tougher. But I think my team is ready for it. We just have to go back and see what we did wrong and correct it."

Andre Hollins added 16 points for the Gophers (19-9, 7-8), who outrebounded Cody Zeller and the Hoosiers by a whopping 44-30 and solidified their slipping NCAA tournament hopes with an emphatic performance against the conference leader. The fired-up fans swarmed the court as the last seconds ticked off, the first time that's happened here since a 2002 win over Indiana.

"There were just too many times when that first shot went up and they were there before we were because we didn't get into their bodies," Hoosiers coach Tom Crean said. "We weren't physical enough on the glass. That's the bottom line."

Zeller, the second-leading shooter in the Big Ten, went 2 for 9. He had nine points with four turnovers. Minnesota had 40 points in the paint to Indiana's 22.

Mbakwe, a sixth-year senior, had a lot to do with that. While positing his conference-leading seventh double-double of the season, the 24-year-old Mbakwe was a man among boys in many ways in this game, dominating both ends of the court when the Gophers needed him most. He grabbed six of Minnesota's 23 offensive rebounds, two of them to keep a key possession alive. His off-balance put-back drew contact for a three-point play with 7:22 left that gave the Gophers a 55-52 lead.

Mbakwe was called for a loudly questioned blocking foul, his fourth, with 4:39 remaining on Zeller's fast-break layup and free throw that put the Hoosiers up 59-58. But Austin Hollins answered with a pump-fake layup that drew a foul for a three-point play and a two-point advantage for the Gophers.

The Hoosiers didn't lead again, and Joe Coleman's fast-break dunk with 2:35 left gave Minnesota a 68-61 cushion that helped it withstand a couple of 3-pointers by Christian Watford and one by Jordan Hulls in the closing minutes. That was the only basket Hulls made after halftime. He had 17 points.

"Just the way we bounced back is unbelievable. We showed that we can beat one of the best teams in the country. Now we have to build off this," said Mbakwe, whose team lost eight of its previous 11 games starting with an 88-81 loss at Indiana on Jan. 12. The Gophers were ranked eighth then. They didn't even receive a vote in the current poll. That could change next week.

The Hoosiers are still in position for their first outright Big Ten regular-season championship since 1993. With another home game against Ohio State on March 5, Indiana could still clinch the title before the finale at Michigan on March 10.

For now, though, the Hoosiers have to regroup and re-establish their inside game after the trampling in the post they endured here.

"They were relentless on the glass. We just didn't do a great job of boxing them out," Oladipo said.

Yahoo CEO right to cut remote work?

Label: Lifestyle

STORY HIGHLIGHTS

Raymond Fisman: Marissa Mayer needs to revive Yahoo, and face time at the office is key

Fisman: Granted, this goes against Utopian vision of everyone working from cafes

Fisman: In-person work means innovations, avoids misunderstood directives

He says more jobs will get done and it'll encourage those who work in a half-empty office

Editor's note: Raymond Fisman is the Lambert Family professor of social enterprise at the Columbia Business School. He is the co-author, with Tim Sullivan, of "The Org: The Underlying Logic of the Office."

(CNN) -- When Yahoo's relatively new CEO Marissa Mayer decreed that workers would be required to show up at the office rather than work remotely, the immediate backlash from outsiders was mostly on the side of the angry Yahoo employees who were losing the comfort and convenience of telecommuting. Inside the company, reactions were mixed.

It struck a deep chord, contrary as it was to the techno-utopian impulse that has helped define Silicon Valley: the idea that someday soon we'll all be working in coffee shops or at kitchen tables, with broadband connections replacing in-person interactions.

Mayer may have been extreme in her demands for face time at the office, but it's the right call for a leader who is working to turn around one of the Internet's laggards.

Raymond Fisman

First, let's consider what's at stake for the company and what Mayer is hoping to accomplish. Yahoo is famous for having bungled its position as a one-time Internet leader. Mayer was brought on specifically to revitalize the benighted company after the departure of Jerry Yang; the firing of Carol Bartz, and the departures of another CEO who inflated his resume and an interim director. All the while, Yahoo has been a company in search of a direction.

What does the end of telecommuting have to do with giving the company a sound footing? The reasons go well beyond the obvious issue of reining in slackers who have taken advantage of Yahoo's reportedly lax monitoring of work done from home.

Talk Back: Is Yahoo wrong to end telecommuting?

Jackie Reses, Yahoo's head of human relations, has it exactly right in the memo she wrote to employees about the policy: Personal interaction is still the most effective way of conveying a company's direction, and keeping tabs on what different parts of the organization are up to. And that's what Mayer has to do with all of Yahoo's 11,500 employees to succeed.

What do in-person meetings accomplish that e-mail can't? Part of the answer lies in time use surveys of CEOs that go back nearly 40 years.

Management scholar Henry Mintzberg was among the first to track how top managers spend their time in the early 1970s. Much to his surprise, he found that around 80% of their time was spent in face-to-face meetings; the subjects of his study had few stretches of more than 10 minutes at a time to themselves.

More recent time use studies by researchers at Harvard, the London School of Economics and Columbia have found that little has changed. Despite the IT revolution, business leaders still spend 80% of their time in face-to-face meetings.

The reason is that there's only so much that one can glean from a written report or a spreadsheet. To cut through the hidden agendas, and office politics, most of the time you need to look someone in the eye and ask them, "Really? How exactly would that work?" It is this probing and questioning that allows effective managers to gather the scraps of information needed to understand what's really going on.

Similarly, all the way down the organizational chart, person-to-person interactions are crucial to ensure that an organization's change of direction isn't misrepresented or garbled in its retelling.

The bland proclamations made in reports and e-mails are given clearer meaning through the way they're communicated in the "high fidelity" that only personal interaction will allow. In-person meetings can also help teams avoid misunderstandings: As one of our friends who runs a virtual workplace puts it, with e-mail exchanges alone, everyone starts to get a bit paranoid.

Finally, the Yahoo memo notes that it's hard to innovate via e-mail exchanges or the occasional agenda-filled meeting. New ideas spring up through chance encounters in the cafeteria line and impromptu office meetings. It's an assertion that's backed up by academic research highlighting the importance of physical proximity in driving scientific progress.

Work at home? Share productivity tips

Yet there are rarely benefits without cost. Lots of tasks are easily managed from a distance. A large number of the affected Yahoo employees are customer-service representatives who aren't going to be driving innovation at the company anyway.

In one study of telecommuting at a Chinese online travel agency, customer-service reps were both happier and more productive when working from home -- probably Yahoo service reps aren't any different from their Chinese counterparts in this regard. And every Yahoo employee surely has some aspects of their jobs that could be done just as well at the kitchen table as in an office cubicle.

But it's hard to create a norm of "physically together" if the office is always half-empty. And once it becomes that way, the half that have been showing up will be less and less inclined to bother. Finally, such a shocking and provocative directive will most certainly have the effect of imbuing the organization with the sense of urgency it needs to get the job done.

Will Yahoo employees come around to appreciating the change? Not necessarily the ones that liked to sleep in or work on a startup on Yahoo's dime, but it may be welcomed by the ones already showing up. Will it be damaging to morale? Possibly, though it may help Yahoo employees to remember that, if they're successful, the change is likely to be temporary.

But the job of the CEO isn't to maximize worker happiness. It's to make sure they get their jobs done. And in driving change at Yahoo, Mayer thinks they need to show up at the office.
