Well: Running in Reverse

This column appears in the Dec. 9 issue of The New York Times Magazine.

Backward running, also known as reverse or retro running, is not as celebrated as barefoot running and will never be mistaken for the natural way to run. But a small body of science suggests that backward running enables people to avoid or recover from common injuries, burn extra calories, sharpen balance and, not least, mix up their daily routine.

The technique is simple enough. Most of us have done it, at least in a modified, abbreviated form, and probably recently, perhaps hopping back from a curb as a bus went by or pushing away from the oven with a roasting pan in both hands. But training with backward running is different. Biomechanically, it is forward motion’s doppelgänger. In a study published last year, biomechanics researchers at the University of Milan in Italy had a group of runners stride forward and backward at a steady pace along a track equipped with force sensors and cameras.

They found that, as expected, the runners struck the ground near the back of their feet when going forward and rolled onto the front of their feet for takeoff. When they went backward though, they landed near the front of their feet and took off from the heels. They tended to lean slightly forward even when running backward. As a result, their muscles fired differently. In forward running, the muscles and tendons were pulled taut during landing and responded by coiling, a process that creates elastic energy (think rubber bands) that is then released during toe-off. When running backward, muscles and tendons were coiled during landing and stretched at takeoff. The backward runners’ legs didn’t benefit from stored elastic energy. In fact, the researchers found, running backward required nearly 30 percent more energy than running forward at the same speed. But backward running also produced far less hard pounding.

What all of this means, says Giovanni Cavagna, a professor at the University of Milan who led the study, is that reverse running can potentially “improve forward running by allowing greater and safer training.”

It is a particularly attractive option for runners with bad knees. A 2012 study found that backward running causes far less impact to the front of the knees. It also burns more calories at a given pace. In a recent study, active female college students who replaced their exercise with jogging backward for 15 to 45 minutes three times a week for six weeks lost almost 2.5 percent of their body fat.

And it aids in balance training — backward slow walking is sometimes used as a therapy for people with Parkinson’s and is potentially useful for older people, whose balance has grown shaky.

But it has drawbacks, Cavagna says — chiefly that you can’t see where you’re going. “It should be done on a track,” he says, “or by a couple of runners, side by side,” one facing forward.

It should be implemented slowly too, because its unfamiliar motion can cause muscle fatigue. Intersperse a few minutes periodically during your regular routine, Cavagna says. Increase the time you spend backward as it feels comfortable.

The good news for serious runners is that backward does not necessarily mean slow. The best recorded backward five-kilometer race time is 19:31, faster than most of us can hit the finish line with our best foot forward.

Memo From Afghanistan: YouTube Ban Is Shrugged Off in Afghanistan

KABUL, Afghanistan — When it comes to YouTube, the government of Afghanistan intends to keep its hand on the switch for now.

More than two months after the Afghan government banned YouTube to prevent the spread of an anti-Islamic video, it has yet to restore access to the popular video Web site. While officials say they hope to lift the block “as soon as possible,” they have offered only a vague sense of what must happen before that can be done.

It is a measure of some of Afghanistan’s complexities, however, that even as Afghan rights advocates have worried about censorship, a common reaction on the street to the YouTube ban has been praise, or at worst ambivalence, even among some of the younger, Internet-savvy set in Kabul.

“That video dishonored our prophet,” said Syed Hamid, 19, a recent high school graduate, in comfortable English. “If YouTube isn’t going to remove the video, then our government is right to block access to it.”

He added: “I don’t need YouTube. I can watch videos on other Web sites.”

When a trailer for the video “Innocence of Muslims,” which portrays the Prophet Muhammad as a crass thug and a womanizer, began to circulate in September, the Afghan government reacted quickly to stem potential violence as riots broke out in other countries. In a move that senior Western officials in Afghanistan praised, the Afghan authorities reached out to religious leaders across the country, urging them to preach restraint and tolerance.

More controversially, officials also decided to impose the ban on YouTube after the company refused to remove the video from its site.

The country remained mostly peaceful, to the relief of the government and Western officials here. Past demonstrations related to religious insensitivity had quickly become deadly: In February, when NATO personnel were seen burning Korans near the Bagram Air Base, Afghans took to the streets in a violent outpouring of rage that led to dozens of deaths.

While Western countries, including most of the ones involved here, recoil at the idea of restricting free speech, the lesson is less clear in Afghanistan. In this case, censorship worked, and in conjunction with the government’s broader strategy almost certainly saved lives.

Still, some are asking the question: Where does the government draw the line on filtering information to its citizens? The answer has consistently been: Anywhere Islam is insulted.

“In the Islamic world, there are certain things that are untouchable,” said Jalal Noorani, senior adviser to the minister of culture and information, who initiated the ban. “We won’t be patient with anything disrespectful to our religion.”

Mr. Noorani said the government had no plans to ban other Web sites, so long as they did not disrespect Islam or incite ethnic violence.

The government had shown a willingness to censor offensive broadcasts before. In 2010, for instance, it shut down Emrooz TV after the local station showed a segment on Shiite Muslims that some Afghans found offensive. And a sustained war of words with Pakistan prompted Afghan officials to ban Pakistani newspapers from eastern Afghanistan in September, claiming they were little more than “propaganda tools for the Taliban.”

While Web sites that focus on vices like gambling and pornography have been banned for years, the government had never before blocked an entire media Web site for hosting an offensive video, officials said. Civil rights groups have argued that the censorship undermines President Hamid Karzai’s promises of transparency and openness.

But for all the controversy over the ban, it hardly seemed to register with many youths here in Kabul.

On a recent afternoon, hundreds of young men gathered in a plaza off the Pul-e-Khesti market, where a de facto cellphone emporium has taken root. Men waved phones as they barked out prices across the crowd. Merchants at makeshift tables charged nominal fees to download music and videos on mobile devices.

The market is just the sort of place the government feared could be a magnet for violence if the video — or even just news of its contents — spread from phone to phone. Although most Afghans do not have computers, cellphones have become ubiquitous over the past decade, and an estimated three-quarters of Afghans have access to mobile devices that allow them to watch videos.

“As long as this anti-prophet video is on YouTube, our government should keep their Web site blocked,” said Javeed Khawrin, 21, who was shopping at the market. “If I had power, I would have destroyed the whole area where this video was taped.”

Subhanullah, 24, an Afghan Army soldier who came to the market to get his phone fixed and who, like many Afghans, uses a single name, said the video “creates more haters among our national army soldiers toward the foreign troops here.”

Attitudes were similar at the city’s Women’s Garden, a sanctuary of roses, leafy trees and swing sets financed by Western aid.

Nilab Khursihid, 18, said she welcomed the government’s decision to keep the ban in place, and suggested even extending it to all material that is hurtful or disrespectful, including cartoons that lampoon Mr. Karzai.

“This is how our community is,” she said, sitting with friends in the garden. “The Internet has misled many of the youth.”

The garden, in the Shahrara neighborhood, boasts a library, a computer lab and a gymnasium for women. Small shops selling toys, lingerie and dresses line the inner wall of the compound. Nearby, a young woman sat uneasily behind the steering wheel of a Toyota, taking a driving lesson, a freedom unknown in the rest of the city.

One shopkeeper, Mariama Ahmadi, 23, who runs a dress store, offered a counterperspective. While she, too, thinks the video should have been taken down, she said, she thinks banning the Web site was a mistake. She said she preferred self-censorship, and the freedom to decide for oneself.

“We can all have our own choices and decide what to watch,” she said, her face framed by a black hijab. “The government shouldn’t be telling people what to do.”

3 Walmart Suppliers Made Goods in Bangladesh Factory

Khurshed Rinku/Associated Press

Burials on Nov. 27 for some of the 112 victims of the garment factory fire in Bangladesh.

Documents found at the Tazreen apparel factory in Bangladesh, where 112 workers died in a fire nearly two weeks ago, indicate that three American garment companies were using the factory during the past year to supply goods to Walmart and its Sam’s Club subsidiary.

The documents — photographed by a Bangladeshi labor organizer after the fire and made available to The New York Times — include an internal production report from mid-September showing that 5 of the factory’s 14 production lines were devoted to making apparel for Walmart.

In a related matter, two officials who attended a meeting held in Bangladesh in 2011 to discuss factory safety in the garment industry said on Wednesday that the Walmart official there played the lead role in blocking an effort to have global retailers pay more for apparel to help Bangladesh factories improve their electrical and fire safety.

Ineke Zeldenrust, international coordinator for the Clean Clothes Campaign, an anti-sweatshop group based in Amsterdam, said Walmart was the company that “most strongly advocated this position.”

The meeting was held in April 2011 in Dhaka, the country’s capital, and brought together global retailers, Bangladeshi factory owners, government officials and nongovernment organizations after several apparel factory fires in Bangladesh had killed dozens of workers the previous winter.

According to the minutes of the meeting, which were made available to The Times, Sridevi Kalavakolanu, a Walmart director of ethical sourcing, along with an official from another major apparel retailer, noted that the proposed improvements in electrical and fire safety would involve as many as 4,500 factories and would be “in most cases” a “very extensive and costly modification.”

“It is not financially feasible for the brands to make such investments,” the minutes said.

Kevin Gardner, a Walmart spokesman, said the company official’s remarks in Bangladesh were “out of context.”

“Walmart has been advocating for improved fire safety with the Bangladeshi government, with industry groups and with suppliers,” he said, adding that the company has helped develop and establish programs to increase fire prevention.

Ms. Zeldenrust said, “Everyone recognized that fire safety was a serious problem and it was a high time to act on it, and Walmart’s position had a very negative impact.” She added, “It gives manufacturers the excuse they’re looking for to say, ‘We’re not to blame.’ ”

Scott Nova, the executive director of the Worker Rights Consortium, a factory monitoring group based in Washington, was also at the meeting. He said that upgrading the factories’ safety would cost a small fraction of what Walmart and other retailers pay for the clothing they import from Bangladesh each year.

Bloomberg News first reported details of the Dhaka meeting on Wednesday.

Walmart has indirectly acknowledged that the factory, Tazreen Fashions, outside Dhaka, was producing some of its apparel, saying in a statement that a supplier had “subcontracted work to this factory without authorization and in direct violation of our policies.” In that statement, issued two days after the Nov. 24 fire, Walmart said, “We have terminated the relationship with that supplier.” Walmart has declined to name the supplier.

After Walmart was shown some of the documents from the factory on Wednesday, Mr. Gardner replied in an e-mail. “As we’ve said, the Tazreen factory was de-authorized months ago,” he wrote. “We don’t comment on specific supplier relationships.”

The photographed documents from the factory indicate that three suppliers — the International Direct Group, Success Apparel and Topson Downs — used the factory to make shirts, shorts and pajamas for Walmart. One document, written in July, provides product descriptions from Success Apparel for Walmart’s Faded Glory house-brand shorts. A photo taken inside the factory after the fire showed a pair of Faded Glory shorts.

The documents indicate that Success Apparel often worked through Simco, a Bangladeshi garment maker.

Mr. Nova of the Worker Rights Consortium said the documents raised questions about Walmart’s statements after the fire.

“It was not a single rogue supplier as Walmart has claimed — there were several different U.S. suppliers working for Walmart in that factory,” Mr. Nova said. “It stretches credulity to think that Walmart, famous for its tight control over its global supply chain, didn’t know about this.”

Mr. Nova works closely with the Bangladesh Center for Worker Solidarity and made the factory documents available.

Investigators also found apparel made for Sears and Disney inside the factory after the fire. Both companies said suppliers had given orders to the factory without their knowledge and authorization.

Mr. Gardner said accredited outside auditors had periodically inspected the factory on Walmart’s behalf. A May 2011 audit gave the factory an “orange” rating, meaning that there were “higher-risk violations” and that it would be re-audited within six months. If a factory gets three orange ratings over two years, it loses Walmart’s approval.

A follow-up audit in August 2011 for Walmart gave Tazreen an improved “yellow” rating, meaning “medium-risk violations.”

Rhode Island Judge Has Stake in Pension Case Outcome

Can a judge rule impartially on pension cuts when her mother, her son, her uncle and even she herself all have a stake in preserving the status quo?

Rhode Island, the site of a sweeping pension overhaul last year, has brought in a prominent New York lawyer to litigate the question: David Boies, perhaps best known for representing Al Gore in the fight over the 2000 presidential election and for waging an antitrust battle against Microsoft on behalf of the government in the 1990s.

Rhode Island’s dispute may not reach quite those dramatic heights, but it is being closely watched as a first major test of whether, and how, financially strained states and cities can cut the benefits of their workers and retirees.

Several public employee unions have sued Gov. Lincoln Chafee and other Rhode Island officials, accusing them of acting illegally when they pushed through a package of money-saving pension cuts last year, including suspending annual cost-of-living increases for most retirees. The unions want the richer benefits restored.

Their five pension lawsuits were assigned to Judge Sarah Taft-Carter of the state Superior Court, who has handled public pension cases before and handed a big victory to the unions in one recent case. Mr. Boies, who at $50 an hour is working for a small fraction of his ordinary fee, is seeking a less conflicted judge, and could even ask to move the case into federal court.

The case has raised questions and strong feelings about the overhaul in Rhode Island, a state so small that it seems as if nearly everybody has friends or family in the pension system. Could the judge see beyond the harsh effects on her own family?

When the subject came up in a hearing in October, Judge Taft-Carter acknowledged that her son, a state trooper, was earning a pension, and her mother, the widow of a mayor, was already receiving one. (The uncle’s pension came to light only later.)

She said she had researched the matter, sought advice from a judicial ethics board and concluded that her relatives’ interests “will not reasonably impact my ability to be impartial.”

Her son joined the state patrol just three years ago, she said, so calculating his pension “requires a large degree of speculation and assumption.” Her mother’s pension was too small to be a factor, she said. (Court papers put it at about $22,000 a year.)

And while the overhaul means the judge’s pension will be smaller despite having to contribute more, she said that was true of all judges in the state: “If my financial interest should require disqualification, then all other state judges would be similarly required to recuse themselves.”

Mr. Boies is expected to appear in court on Friday and cite the state’s judicial code of conduct, which requires judges to recuse themselves when their spouses, parents or children have an economic stake in the litigation before them.

The state’s Supreme Court justices, who have been asked for a review, are also members of the state pension system.

In an interview, Mr. Boies said that challenging Judge Taft-Carter’s impartiality was just “the first step,” and the bigger issue was whether any judges in Rhode Island could handle the case, given their personal stakes. Companies routinely have their pension disputes decided by federal courts, which grant more leeway in changing pension plans.

“The plaintiffs brought this case the way they did to try to avoid federal jurisdiction,” Mr. Boies said.

Whatever the outcome of the hearing, Mr. Boies said he would continue to represent Rhode Island until all of the lawsuits and appeals were decided.

Mr. Boies, whose standard fee is $1,250 an hour, said $50 an hour was “the same fee that I charged the United States when I represented the Department of Justice in the Microsoft case.”

Mr. Boies became involved, he said, because he was convinced that Rhode Island’s pension troubles were just the tip of a $5 trillion iceberg of unsecured retirement promises to the nation’s millions of public workers. “This is something that can cripple state and municipal governments at a time when the federal government is, more and more, cutting back on the services it provides,” he said.

Public employee unions, in Rhode Island and elsewhere, argue that people like Mr. Boies are exaggerating the size of America’s total public pension shortfall.

This article has been revised to reflect the following correction:

Correction: December 4, 2012

An earlier version of this article wrongly attributed the following quotation: Rhode Island’s effort is “the clearest example of fundamental pension reform that we have right now,” Ms. Monahan said. “Even though whatever Rhode Island decides doesn’t serve as actual precedent for other states, other states and cities still want to know if it can work.” The quote was from Amy Monahan, not Gina Raimondo.

Willis Whitfield, Clean Room Inventor, Dies at 92

The enemy was very small but it was everywhere. World peace, medical advancement, iTunes — all would eventually be threatened.

Half a century ago, as a rapidly changing world sought increasingly smaller mechanical and electrical components and more sanitary hospital conditions, one of the biggest obstacles to progress was air, and the dust and germs it contains.

Stray particles a few microns wide could compromise the integrity of a circuit board of a nuclear weapon. Unchecked bacteria could quickly infect a patient after a seemingly successful operation. Microprocessors, not yet in existence, would have been destroyed by dust. After all, an average cubic foot of air contained three million microscopic particles, and even the best efforts at vacuuming and wiping down a high-tech work space could only reduce the rate to one million.

Then, in 1962, Willis Whitfield invented the clean room.

“People said he was a fraud,” recalled Gilbert V. Herrera, the director of microsystems science and technology at Sandia National Laboratories in Albuquerque. “But he turned out to be right.”

Mr. Whitfield, who worked at Sandia from 1954 to 1984, died on Nov. 12 in Albuquerque. He was 92. The cause was prostate cancer, his wife, Belva, said.

His clean rooms blew air in from the ceiling and sucked it out from the floor. Filters scrubbed the air before it entered the room. Gravity helped particles exit. It might not seem like a complicated concept, but no one had tried it before. The process could completely replace the air in the room 10 times a minute.

Particle detectors in Mr. Whitfield’s clean rooms started showing numbers so low — a thousand times lower than other methods — that some people did not believe the readings, or Mr. Whitfield. He was questioned so much that he began understating the efficiency of his method to keep from shocking people.

“I think Whitfield’s wrong,” a scientist from Bell Labs finally said at a conference where Mr. Whitfield spoke. “It’s actually 10 times better than he’s saying.”

Willis James Whitfield was born in Rosedale, Okla., on Dec. 6, 1919. In addition to his wife, his survivors include his sons, James and Joe; a sister, Amy Blackburn; and a brother, Lawrence.

Mr. Whitfield became fascinated with electronics as a young man and received a two-year degree in the field after high school. He served in the Navy late in World War II, working with experimental electronic systems for aircraft. In 1952, he received a bachelor’s degree in physics and math from Hardin-Simmons University in Abilene, Tex.

By 1954 he was working at Sandia, which was involved in making parts for nuclear weapons and at the time was overseen by the Atomic Energy Commission. Mr. Whitfield’s duties soon included contamination control. By 1960, he had established his basic idea for the clean room.

“I thought about dust particles,” Mr. Whitfield told Time magazine in 1962. “Where are these rascals generated? Where do they go?”

The clean room was patented through Sandia, and the government shared it freely among manufacturers, hospitals and other industries.

Mr. Whitfield’s original clean room was only about six feet high, built as a small, self-contained unit. Some modern electronic devices, including the iPhone, are now built in China in huge clean rooms in structures that are more than a million square feet. Workers wear protective clothing, and other anticontamination methods have been added, but they still depend on Mr. Whitfield’s approach to suck up dust.

“Relative to these electronics, the particles are just massive boulders that would short out all of your electronics and make them not work,” Mr. Herrera said. “The core technology, just the cleaning part, hasn’t really changed a lot.”

Mrs. Whitfield said she was often been asked if her husband was a particularly fastidious man, and she always noted that he tended not to put his shoes away. He did live in a tidy house, though, and colleagues say he never tired of getting out a flashlight and shining it sideways across his coffee table to illuminate the prevalence of tiny dust particles that most people never notice.

Video Games: Little Inferno; Hitman; Assassin’s Creed III; Persona 4 Golden; Angry Birds Star Wars; My Little Pony

Ubisoft

Ratonhnhaké:ton is a half-British, half-Mohawk assassin in Revolutionary America.

Released on Nov. 18

Developed by Tomorrow Corporation

For PC, Mac, Linux and Wii U

Rated T for Teen (drug reference and crude humor)

Here’s an odd one. Little Inferno is an interactive fireplace. It’s an emotional, interactive fireplace with a story line and some notions about the dangers of amusing ourselves with distracting trifles.

At first this strange creation appears to be a simple puzzle game consisting of little more than a fireplace, a catalog of items to burn and 99 clues that challenge the player to burn these things in proper combinations. One clue is “Movie Night.” Burn the popcorn. Burn the TV. A weirder one is “Bike Pirate.” Burn the wooden bike. Burn the pirate.

As you play, an unseen character begins to send letters. They burn, too, but something seems off. The messages are alternately cheerful and sad, a wee bit wicked and increasingly desperate.

The purpose of the pyromaniac pastime becomes smoky with doubt. Why are we doing this? What are we missing? It’s odd enough to play a new video game that questions our decision to play video games. That it’s an interactive fireplace game that does this is all the stranger and more wonderful. It’s a yule log for our times.

HITMAN

Absolution

Released on Nov. 20

Developed by IO Interactive

Published by Square Enix

For PC, Xbox 360 and

PlayStation 3

Rated M for Mature (intense violence, partial nudity and strong language)

It’s a vile, dangerous world in Hitman: Absolution. Nearly everyone is in need of a good killing, and Agent 47, the depilated murder machine at the center of the long-running Hitman franchise, is just the man for the job.

Absolution is consistent with the setup of past Hitman games: At the start of a level, 47 is given an assassination target, and he must make his way through semi-open areas by any of a number of possible routes. The reactive artificial intelligence keeps things enjoyably unpredictable, and the best levels feel like a buffet of sadistic improvisation.

The story is pure B-movie hogwash. It’s mostly enjoyable in a certain exploitive way, but it often feels as if the writers were trying too hard.

When it gets cooking, Hitman: Absolution evokes the feeling of a deadly, measured dance. It’s a tango between you and the computer, with each party alternately taking the lead through arenas that shift and upset expectations.

ASSASSIN’S CREED III

Released on Oct. 30

Developed and published by Ubisoft

For PlayStation 3, Xbox 360, Wii U and PC

Rated M for Mature (blood, intense violence, sexual themes and strong language)

Assassin’s Creed III is really the fifth major Assassin’s Creed game. The numbering signifies that this new historical epic is a shift, as this Ubisoft series about the ancestral lives of a man named Desmond Miles leaps to its third era. Finished with the 12th-century crusades and 15th-century Renaissance Italy, Assassin’s Creed now lets us do interactive historical tourism in Boston, New York and the nearby woods of Revolutionary America.

Assassin’s Creed games are lavish action-adventure blockbusters. In this new one, we primarily play as a young, bitter, half-British, half-Mohawk greenhorn assassin named Ratonhnhaké:ton, who finds himself crossing paths and sometimes doing the bidding of Sam Adams, Paul Revere, George Washington and other real figures. Most of the bad guys are red coats with slow-firing muskets. We’re best with a tomahawk and a bow and arrow.

The new game involves a lot of climbing and killing across a sprawling landscape of bustling cities and gorgeous frontier. Add in a mix of awkwardly instituted horseback riding, homestead building, trading, trapping, hunting and, at the wheel of your own tall-masted warship, epic naval combat. There is much to do and witness in a ripped-from-the-history-books adventure that is refreshingly unwilling to ignore the unsavory aspects of America’s birth. A lengthy production cycle didn’t spare the game from a wealth of bugs that are only now being patched out.

The series’s low-key multiplayer games of competitive assassination return, but the star of this epic is something that might seem almost quaint: Assassin’s Creed III is easily the best tree-climbing simulator in history.

PERSONA 4 GOLDEN

Changing of the Guard: How Crash Cover-Up Altered China’s Succession

BEIJING — “Thank you. I’m well. Don’t worry,” read the post on a Chinese social networking site. The brief comment, published in June, appeared to come from Ling Gu, the 23-year-old son of a high-powered aide to China’s president, and it helped quash reports that he had been killed in a Ferrari crash after a night of partying.

It only later emerged that the message was a sham, posted by someone under Mr. Ling’s alias — almost three months after his death.

The ploy was one of many in a tangled effort to suppress news of the Ferrari crash that killed Mr. Ling and critically injured two young female passengers, one of whom later died. The outlines of the affair surfaced months ago, but it is now becoming clearer that the crash and the botched cover-up had more momentous consequences, altering the course of the Chinese Communist Party’s once-in-a-decade leadership succession last month.

China’s departing president, Hu Jintao, entered the summer in an apparently strong position after the disgrace of Bo Xilai, previously a rising member of a rival political network who was brought down when his wife was accused of murdering a British businessman. But Mr. Hu suffered a debilitating reversal of his own when party elders — led by his predecessor, Jiang Zemin — confronted him with allegations that Ling Jihua, his closest protégé and political fixer, had engineered the cover-up of his son’s death.

According to current and former officials, party elites, and others, the exposure helped tip the balance of difficult negotiations, hastening Mr. Hu’s decline; spurring the ascent of China’s new leader, Xi Jinping; and playing into the hands of Mr. Jiang, whose associates dominate the new seven-man leadership at the expense of candidates from Mr. Hu’s clique.

The case also shows how the profligate lifestyles of leaders’ relatives and friends can weigh heavily in backstage power tussles, especially as party skulduggery plays out under the intensifying glare of media.

Numerous party insiders provided information regarding the episode, speaking on the condition of anonymity for fear of reprisals from the authorities. Officials have investigated the aftermath of the car wreck, they say, including looking into accusations that a state oil company paid hush money to the families of the two women.

Under Mr. Hu, Mr. Ling had directed the leadership’s administrative center, the General Office, but was relegated to a less influential post in September, ahead of schedule. Last month, he failed to advance to the 25-person Politburo and lost his seat on the influential party secretariat.

Mr. Hu, who stepped down as party chief, immediately yielded his post as chairman of the military, meaning he will not retain power as Mr. Jiang did. “Hu was weakened even before leaving office,” said a midranking official in the Organization Department, the party’s personnel office.

Mr. Ling’s future remains unsettled, with party insiders saying that his case presents an early test of whether Mr. Xi intends to follow through on public promises to fight high-level corruption.

“He can decide whether to go after Ling Jihua or not,” said Wu Guoguang, a former top-level party speechwriter, now a political scientist at the University of Victoria in British Columbia. “Either way, this is a big card in Xi Jinping’s hand.”

Mr. Ling, 56, built his career in the Communist Youth League. At an early age, he secured the patronage of Mr. Hu, who led the Youth League in the early 1980s and brought Mr. Ling to the General Office in 1995. “Hu didn’t come with a lot of friends, but Ling was someone he knew he could trust,” said the Organization Department official. “Officials said that if Ling called, it was like Hu calling.”

Mr. Ling played a central role in moving Youth League veterans into high offices and undermining Mr. Hu’s adversaries. Mr. Ling also wielded leverage over Internet censorship of leaders’ affairs, and sought to use it to benefit his patron.

“Negative publicity, including untruths, about Xi Jinping were not suppressed the way publicity about Hu Jintao was,” said one associate of party leaders.

As his influence grew, Mr. Ling tried to keep a low profile. About a decade ago, his wife closed a software company she owned and formed a nonprofit foundation that incubates young entrepreneurs. The couple sent their son, Ling Gu, to an elite Beijing high school under an alias, Wang Ziyun. “Ling Jihua told his family not to damage his career,” a former Youth League colleague said. “But it seems it can’t be stopped.”

Still living under an alias, Ling Gu graduated from Peking University last year with an international relations degree and began graduate studies in education. One of his instructors said his performance plunged later in his undergraduate years. “I think there were too many lures, too much seduction,” he said.

Before dawn on March 18, a black Ferrari Spider speeding along Fourth Ring Road in Beijing ricocheted off a wall, struck a railing and cracked in two. Mr. Ling was killed instantly, and the two young Tibetan women with him were hospitalized with severe injuries. One died months later, and the other is recovering, party insiders said.

More Dads Buy the Toys, So Barbie, and Stores, Get Makeovers

Barbies are for girls and construction sets are for boys. Or are they?

For the first time in Barbie’s more than 50-year history, Mattel is introducing a Barbie construction set that underscores a huge shift in the marketplace. Fathers are doing more of the family shopping just as girls are being encouraged more than ever by hypervigilant parents to play with toys (as boys already do) that develop math and science skills early on.

It’s a combination that not only has Barbie building luxury mansions — they are pink, of course — but Lego promoting a line of pastel construction toys called Friends that is an early Christmas season hit. The Mega Bloks Barbie Build ’n Style line, available next week, has both girls — and their fathers — in mind.

“Once it’s in the home, dads would very much be able to join in this play that otherwise they might feel is not their territory,” said Dr. Maureen O’Brien, a psychologist who consulted on the new Barbie set.

Consumer surveys show that men are increasingly making the buying decisions for families, reflecting the growth in two-income households and those in which the women work and the men stay home. One-fifth of fathers with preschool-age children and working wives said they were the primary caretaker in 2010, according to the latest Census Bureau data. And 37.6 percent of working wives earned more than their husbands in 2011, up from 30.7 percent 10 years earlier.

“Kids are going to grow up with dads that give them baths and drive them to soccer and are cutting up oranges for team snacks,” said Liz Ross, president for North America of BPN, part of the IPG Mediabrands holding company, which recently completed a study on male consumers. “What will go away, albeit slowly, is the image or the perception of the befuddled dad.”

The change is having consequences beyond toys. Consumer products have traditionally been marketed to appeal to women, and stores have been designed for women’s sensibilities. Now, some brands and stores are catering directly to male decision-makers. Sears is reorganizing stores to put tools next to work wear, for instance, based on men’s preferences. Procter & Gamble is working on men’s grooming aisles at top retailers, a nod to the fact that women are no longer choosing shampoos or shaving creams for their husbands. With the selling point that it helps girls develop spatial reasoning, the Barbie set, a joint effort of Mattel and the toy company Mega Bloks, is also meant to pique fathers’ interest.

“Dad is a bigger influencer in terms of toy purchases over all, and this sets up well for that, because the construction category is something Dad grew up with and definitely has strong feelings and emotions about,” said Vic Bertrand, chief innovation officer of Mega Brands, Mega Bloks’ parent company.

Construction sets for girls are a speedy growth category, thanks to Lego’s introduction of its Friends line in January. Despite criticism that those sets were sexist — themes include a beauty shop and a fashion studio — Lego’s chief executive said in August that the company sold twice as many of the sets in the first half of the year as it had expected, and retailers like Amazon and Target have named them hot holiday toys.

Anne Marie Kehoe, vice president of toys for Walmart U.S., said that, with the Barbie addition, construction toys aimed at girls will represent about 20 percent of the toy construction category by the end of this year, while last year there were just a handful of products.

Research shows that playing with blocks, puzzles and construction toys helps children with spatial development, said Dr. Susan C. Levine, chairwoman of the psychology department at the University of Chicago and co-principal investigator at the National Science Foundation’s Spatial Intelligence and Learning Center. Even controlling for other skills such as verbal and numerical skills, she said, children with better spatial thinking are more likely to eventually go into mathematics, engineering, science and technology.

She said that a set aimed at girls could be beneficial, if only because it might increase girls’ likelihood of participating in construction activities.

Dr. O’Brien, the consultant on the new Barbie set, said adults had traditionally been “the limiting factor” in why girls have not played with those toys as often.

Recently, she said, there has been a shift in attitudes, as parents study research on development and spatial play. “For this particular product, one of the advantages is you can appeal to both moms and dads,” she said of the construction set.

During her research, Dr. O’Brien said, she watched a grandfather jump in to explain building principles to his granddaughter, who was playing with the Barbie. Still, the construction set is not exactly dump trucks and dirt. It remains “unapologetically all girl,” said Stephanie Cota, senior vice president of global marketing for Barbie, girls’ brands and games at Mattel.

The Mega Bloks building pieces are pink (Pantone 219, the signature Barbie color), and the construction choices are scenes like a fashion boutique, a mansion and an ice cream cart. Each set comes with a small Barbie figure that can be snapped into the scene.

Mattel, the world’s largest toy maker, still leans heavily on Barbie, one of its most popular and longest-running franchises. However, pressure to update Barbie has been high — Mattel has introduced Barbies with video cameras and digital cameras in recent years.

Yet sales of Barbie in North America through September fell 1 percent, even as sales of Mattel’s other girl brands, like Disney Princess dolls, rose 44 percent. Mega Brands makes just a fraction of what its larger rival Lego does, and had revenues of about $376 million last year.

The Barbie brand, which tends to raise feminists’ ire for its overly sexualized dolls, not to mention the 1992 version saying “Math class is tough,” has already taken some high-arched steps toward gender equality. A computer-engineer Barbie was introduced two years ago, for instance, with the support of the Society of Women Engineers.

This time, though, the introduction appears to be a response more to market changes than to critics.

Girls “don’t necessarily care about, ‘That’s a boy toy; that’s not for me,’ ” said Ms. Cota of Mattel. “Now, more so than ever, girls are looking at what’s fun, what they like.”

With Some Hospitals Closed After Hurricane Sandy, Others Pick Up Slack

A month after Hurricane Sandy struck New York City, unexpectedly shutting down several hospitals, one Upper East Side medical center had so many more emergency room patients than usual that it was parking them in its lobby.

White and blue plastic screens had been set up between the front door and the elevator banks in the East 68th Street building of that hospital, NewYork-Presbyterian/Weill Cornell. The screens shielded 10 gurneys and an improvised nursing station from the view of people obliviously walking in and out of the soaring, light-filled atrium.

“It’s like a World War II ward,” Teri Daniels, who had been waiting a day and a half with a relative who needed to be admitted, said last week.

Since the storm, a number of New York City hospitals have been scrambling to deal with a sharp increase in patients, forcing them to add shifts of doctors and nurses on overtime, to convert offices and lobbies to use for patients’ care, and even, in one case, to go to a local furniture store to buy extra beds.

At Beth Israel Medical Center, 11 blocks south of the Bellevue Hospital Center emergency room, which was shuttered because of storm damage, the average number of visits to the E.R. per day has risen to record levels. Visits have increased by 24 percent this November compared with last, and the numbers show no sign of dropping. Hospital admissions have risen 12 percent compared with last November.

Most of the rise in volume is from patients who had never been to Beth Israel before. An emergency room doctor at the hospital described treating one patient who said he had been born at Bellevue and had never before gone anywhere else.

Emergency room visits have gone up 25 percent at NewYork-Presybterian/Weill Cornell, which in Bellevue’s absence is the closest high-level trauma center — treating stab wounds, gun wounds, people hit by cars and the like — in Manhattan from 68th Street south. Stretchers holding patients have been lined up like train cars around the nursing station and double-parked in front of stretcher bays.

In Brooklyn, some patients in Maimonides Medical Center’s emergency room who need to be admitted are waiting two or three days for a bed upstairs, instead of four or five hours. Almost every one of the additional 1,100 emergency patients this November compared with last November came from four ZIP codes affected by the storm and served by Coney Island Hospital, a public hospital that was closed because of storm damage.

The number of psychiatric emergency patients from those same ZIP codes has tripled, in a surge that began three days before the hurricane, perhaps fueled by anxiety, as well as by displacement from flooded adult homes or programs at Coney Island Hospital, doctors said.

The Maimonides psychiatric emergency room bought five captain’s beds — which do not have railings that can be used for suicide attempts — at a local furniture store, to accommodate extra patients. The regular emergency room had to buy 27 new stretchers after the hurricane, “and we probably need a few more,” the department’s chief, Dr. John Marshall, said.

The emergency room and inpatient operations of four hospitals remain closed because of flooding and storm damage. Besides Bellevue and Coney Island, NYU Langone Medical Center and the VA New York Harbor Healthcare System, both near Bellevue on the East Side of Manhattan, are closed.

While the surge in traffic to other hospitals has been a burden, it has also been a boon, bringing more revenue.

On the Upper East Side, the storm has helped Lenox Hill Hospital, which has a history of financial problems. It took two or three wards that had been turned into offices and converted them back to space for patients. Emergency room visits are up 10 percent, and surgery has been expanded to seven days a week from five.

“We usually operate at slightly over 300 beds, and now we’re at well over 550,” Carleigh Gustafson, director of emergency nursing, said.

Conversely, administrators at the shuttered hospitals, especially NYU Langone, a major teaching center, worry that their patients and doctors are being raided, with some never to return.

NYU’s salaried doctors are being paid through January, on the condition that they do not take another job. But at the same time, they need a place to practice, so NYU administrators have been arranging for them to work as far away as New Jersey until the hospital reopens. Lenox Hill alone has taken on close to 300 NYU doctors, about 600 nurses, and about 150 doctors in training, fellows and medical students.

Obstetricians and surgeons from the closed hospitals have been particularly disadvantaged, since they are dependent on hospitals to treat their patients. Many displaced surgeons have been reduced to treating only the most desperately ill, and operating on nights and weekends, when hospitals tend to be least well staffed.

“I think there’s no question that a lot of people have postponed anything that they can postpone that is elective,” said Dr. Andrew W. Brotman, senior vice president at NYU.

In mid-November, Dr. Michael L. Brodman, chairman of obstetrics at Mount Sinai Medical Center, sent out a memo saying his department had taken on 26 NYU physicians, as well as nurses and residents, but “clearly, that is too much for us to handle long term.”

Since then, 15 of the physicians have gone to New York Downtown Hospital, while Mount Sinai has retained 11 doctors and 26 nurses.

“We are guests in other people’s homes,” Dr. Brotman of NYU said, “and we are guests who have to some degree overstayed their welcome.”
