Boeing 787 Completes Test Flight

A Boeing 787 test plane flew for more than two hours on Saturday to gather information about the problems with the batteries that led to a worldwide grounding of the new jets more than three weeks ago.

The flight was the first since the Federal Aviation Administration gave Boeing permission on Thursday to conduct in-flight tests. Federal investigators and the company are trying to determine what caused one of the new lithium-ion batteries to catch fire and how to fix the problems.

The plane took off from Boeing Field in Seattle heading mostly east and then looped around to the south before flying back past the airport to the west. It covered about 900 miles and landed at 2:51 p.m. Pacific time.

Marc R. Birtel, a Boeing spokesman, said the flight was conducted to monitor the performance of the plane’s batteries. He said the crew, which included 13 pilots and test personnel, said the flight was uneventful.

He said special equipment let the crew check status messages involving the batteries and their chargers, as well as data about battery temperature and voltage.

FlightAware, an aviation data provider, said the jet reached 36,000 feet. Its speed ranged from 435 to 626 miles per hour.

All 50 of the 787s delivered so far were grounded after a battery on one of the jets caught fire at a Boston airport on Jan. 7 and another made an emergency landing in Japan with smoke coming from the battery.

The new 787s are the most technically advanced commercial airplanes, and Boeing has a lot riding on their success. Half of the planes’ structural parts are made of lightweight carbon composites to save fuel.

Boeing also decided to switch from conventional nickel cadmium batteries to the lighter lithium-ion ones. But they are more volatile, and federal investigators said Thursday that Boeing had underestimated the risks.

The F.A.A. has set strict operating conditions on the test flights. The flights are expected to resume early this week, Mr. Birtel said.

Battery experts have said it could take weeks for Boeing to fix the problems.

India Ink: Newswallah: Bharat Edition

Himachal Pradesh: Heavy snowfall for three straight days in the hill state has shut down several arterial roads in the interior areas on Thursday, affecting vehicular traffic, according to an IANS report on the NDTV Web site. In Shimla, a popular holiday destination, at least 10 people, most of them tourists, were injured while walking on the slippery roads, the report said.

Sikkim: The ecologically rich state, located in the lower ranges of the Himalayas, will host the International Flower Show from Feb. 23 to 27, according to an IANS report cited in the Hindustan Times. The state is home to almost 5,000 varieties of flowers, and Sikkim’s state government is keen to promote floriculture and related activities as an important source of livelihood in the coming years, the report said.

Assam: A review committee decided to sign off on the government’s decision to block 306 Twitter accounts after last year’s ethnic clashes in the Kokrajhar district of Assam, the Press Trust of India reported. The committee observed that the accounts could inflame religious tensions in the country.

Gujarat: On Wednesday, a candidate for a local village election in Gujarat’s Sabarkantha district was arrested, along with his manager, for allegedly forcing 100 people to put their hands in boiling oil to prove their loyalty to him, The Hindu reported. The candidate, Dinesh Parmar, who lost the election, had allegedly told the people that their hands would not be burned if they had indeed voted for him.

Rajasthan: A village council in Rajasthan’s Bikaner district decided to impose a fine on those who consumed alcohol or hunted animals, the Press Trust of India reported. At a meeting of the village council, it was decided that the penalty amount would range between 1,000 rupees and 11,000 rupees (about $19 to $206).

Karnataka: About 26 members of Bangalore-based women’s rights groups were taken into custody Tuesday but were later released, The Hindu said. These activists held demonstrations in front of the Raj Bhavan, or the governor’s mansion, to protest the central government’s new laws to deter violence against women, which the activists said ignored important recommendations by a government-appointed committee.

Bryant leads Lakers over Bobcats 100-93

CHARLOTTE, N.C. (AP) — Even though Kobe Bryant and the Lakers were able to escape with a 100-93 win Friday night over the Charlotte Bobcats, the Los Angeles star was left feeling "irritated" after the game.

Irritated at his team's shot selection.

Irritated at his team's selfishness.

And especially irritated that the Lakers needed to overcome a 20-point deficit to beat the NBA's worst team.

"We have to play the right way," Bryant said. "When we have shots available, we take them. If we don't, move the ball on. It can't be about individual touches. It can't be about that."

Still, the Lakers won.

Bryant shrugged off a scoreless first half — he attempted only two shots — to finish with 20 points, eight assists and seven rebounds and the Lakers improved to 4-2 on their road trip heading into Sunday's game in Miami against the Heat.

Bryant didn't come out for warm-ups to start the second half.

But he was there to provide the spark the lackluster Lakers needed in the third quarter. He scored 14 of his points in the final period, including a driving layup with 40 seconds left to push the lead to five and help seal the win.

"In the second half I got in position where I could catch it and turn and shoot it a little bit," Bryant said. "They were reluctant to double team because we started knocking down some shots. I think that makes the game a lot easier."

Steve Nash and Earl Clark each had 17 points and Dwight Howard had 12 points, all in the first half, and 11 rebounds for the Lakers (24-27).

Howard played his second straight game despite nursing an injured right shoulder.

"Continuity," Howard said when asked of the Lakers offensive woes. "We have to do a better job of spreading everything out and moving and getting everybody involved. When we do that, we are pretty good."

Byron Mullens and Gerald Henderson each had 20 points for the Bobcats, who have lost six straight.

Charlotte led 71-51 in the third quarter, but the Lakers stormed back behind a 9-0 run. They cut the lead to one on a driving layup by Bryant with 6:06 left in the game and Antawn Jamison gave the Lakers their first lead with 4:46 remaining on a left-handed finger roll in the lane.

The Lakers took the lead for good at 92-91 when Jodie Meeks made a 3-pointer with 3:02 left in the game.

Lakers coach Mike D'Antoni wasn't pleased with the overall effort, but liked that his team bounced back after a 116-95 loss to the Boston Celtics the night before.

"We just got to be able to put our earplugs in, or mufflers on, or blinders on," D'Antoni said. "It's like the Kentucky Derby with horses, just get those blinders on and just get out there and run.

"We have so much stuff going on out here that every little thing is blown to bits and whether it is right or wrong or blown out of proportion it is. But, it affects us. It is a distraction. It saps energy. We got to be able to just close that out somehow."

The Lakers have been unpredictable this season, particularly on the road where they were 8-17 coming into this game.

Before Friday night's game against Charlotte, D'Antoni was asked if the Bobcats were a dangerous opponent for his team.

"We're playing, aren't we? (Then) there's a danger," D'Antoni said with a laugh. "If they play the national anthem, we're in danger."

He was right.

The Lakers started slow, looking out of sync just as they have for a good portion of the season as pick and rolls turned into turnovers and layups on the other end.

Nash had four early turnovers and Howard threw a pass across court that hit the side of the backboard.

The Lakers turned the ball over five times in the game's first eight minutes and fell behind 20-9.

Bryant missed his only two shots in the first half, his slowest start since March 31, 2012, when he went three quarters without scoring a point before beating the New Orleans Hornets on a game-winning shot.

The game was similar to earlier this season when the Bobcats led by 18 in Los Angeles only to squander the lead.

"We had them down pretty much the whole game," Bobcats guard Kemba Walker said. "You know, they made a really good run. Kobe made a lot of good plays, made the right passes and guys just made shots."

NOTES: Bobcats rookie Michael Kidd-Gilchrist returned to action Friday after missing two games with a concussion. ... At halftime Bryant had five rebounds, two assists and no points. ... The Bobcats had been one of three teams with a .500 or better record all-time against the Lakers, but fell to 8-9 with Friday night's loss.

In Nigeria, Polio Vaccine Workers Are Killed by Gunmen

At least nine polio immunization workers were shot to death in northern Nigeria on Friday by gunmen who attacked two clinics, officials said.

The killings, with eerie echoes of attacks that killed nine female polio workers in Pakistan in December, represented another serious setback for the global effort to eradicate polio.

Most of the victims were women and were shot in the back of the head, local reports said.

A four-day vaccination drive had just ended in Kano State, where the killings took place, and the vaccinators were in a “mop-up” phase, looking for children who had been missed, said Sarah Crowe, a spokeswoman for the United Nations Children’s Fund, one of the agencies running the eradication campaign.

Dr. Mohammad Ali Pate, Nigeria’s minister of state for health, said in a telephone interview that it was not entirely clear whether the gunmen were specifically targeting polio workers or just attacking the health centers where vaccinators happened to be gathering early in the morning. “Health workers are soft targets,” he said.

No one immediately took responsibility, but suspicion fell on Boko Haram, a militant Islamist group that has attacked police stations, government offices and even a religious leader’s convoy.

Polio, which once paralyzed millions of children, is now down to fewer than 1,000 known cases around the world, and is endemic in only three countries: Nigeria, Pakistan and Afghanistan.

Since September — when a new polio operations center was opened in the capital and Nigeria’s president, Goodluck Jonathan, appointed a special adviser for polio — the country had been improving, said Dr. Bruce Aylward, chief of polio eradication for the World Health Organization. There have been no new cases since Dec. 3.

While vaccinators have not previously been killed in the country, there is a long history of Nigerian Muslims shunning the vaccine.

Ten years ago, immunization was suspended for 11 months as local governors waited for local scientists to investigate rumors that it caused AIDS or was a Western plot to sterilize Muslim girls. That hiatus let cases spread across Africa. The Nigerian strain of the virus even reached Saudi Arabia when a Nigerian child living in hills outside Mecca was paralyzed.

Heidi Larson, an anthropologist at the London School of Hygiene and Tropical Medicine who tracks vaccine issues, said the newest killings “are kind of mimicking what’s going on in Pakistan, and I feel it’s very much prompted by that.”

In a roundabout way, the C.I.A. has been blamed for the Pakistan killings. In its effort to track Osama bin Laden, the agency paid a Pakistani doctor to seek entry to Bin Laden’s compound on the pretext of vaccinating the children — presumably to get DNA samples as evidence that it was the right family. That enraged some Taliban factions in Pakistan, which outlawed vaccination in their areas and threatened vaccinators.

Nigerian police officials said the first shootings were of eight workers early in the morning at a clinic in the Tarauni neighborhood of Kano, the state capital; two or three died. A survivor said the two gunmen then set fire to a curtain, locked the doors and left.

“We summoned our courage and broke the door because we realized they wanted to burn us alive,” the survivor said from her bed at Aminu Kano Teaching Hospital.

About an hour later, six men on three-wheeled motorcycles stormed a clinic in the Haye neighborhood, a few miles away. They killed seven women waiting to collect vaccine.

Ten years ago, Dr. Larson said, she joined a door-to-door vaccination drive in northern Nigeria as a Unicef communications officer, “and even then we were trying to calm rumors that the C.I.A. was involved,” she said. The Iraq and Afghanistan wars had convinced poor Muslims in many countries that Americans hated them, and some believed the American-made vaccine was a plot by Western drug companies and intelligence agencies.

Since the vaccine ruse in Pakistan, she said, “Frankly, now, I can’t go to them and say, ‘The C.I.A. isn’t involved.’ ”

Dr. Pate said the attack would not stop the newly reinvigorated eradication drive, adding, “This isn’t going to deter us from getting everyone vaccinated to save the lives of our children.”

Aminu Abubakar contributed reported from Kano, Nigeria.

John E. Karlin, 1918-2013: John E. Karlin, Who Led the Way to All-Digit Dialing, Dies at 94

Courtesy of Alcatel-Lucent USA

John E. Karlin, a researcher at Bell Labs, studied ways to make the telephone easier to use.

A generation ago, when the poetry of PEnnsylvania and BUtterfield was about to give way to telephone numbers in unpoetic strings, a critical question arose: Would people be able to remember all seven digits long enough to dial them?

And when, not long afterward, the dial gave way to push buttons, new questions arose: round buttons, or square? How big should they be? Most crucially, how should they be arrayed? In a circle? A rectangle? An arc?

For decades after World War II, these questions were studied by a group of social scientists and engineers in New Jersey led by one man, a Bell Labs industrial psychologist named John E. Karlin.

By all accounts a modest man despite his variegated accomplishments (he had a doctorate in mathematical psychology, was trained in electrical engineering and had been a professional violinist), Mr. Karlin, who died on Jan. 28, at 94, was virtually unknown to the general public.

But his research, along with that of his subordinates, quietly yet emphatically defined the experience of using the telephone in the mid-20th century and afterward, from ushering in all-digit dialing to casting the shape of the keypad on touch-tone phones. And that keypad, in turn, would inform the design of a spate of other everyday objects.

It is not so much that Mr. Karlin trained midcentury Americans how to use the telephone. It is, rather, that by studying the psychological capabilities and limitations of ordinary people, he trained the telephone, then a rapidly proliferating but still fairly novel technology, to assume optimal form for use by midcentury Americans.

“He was the one who introduced the notion that behavioral sciences could answer some questions about telephone design,” Ed Israelski, an engineer who worked under Mr. Karlin at Bell Labs in the 1970s, said in a telephone interview on Wednesday.

In 2013, the 50th anniversary of the introduction of the touch-tone phone, the answers to those questions remain palpable at the press of a button. The rectangular design of the keypad, the shape of its buttons and the position of the numbers — with “1-2-3” on the top row instead of the bottom, as on a calculator — all sprang from empirical research conducted or overseen by Mr. Karlin.

The legacy of that research now extends far beyond the telephone: the keypad design Mr. Karlin shepherded into being has become the international standard on objects as diverse as A.T.M.’s, gas pumps, door locks, vending machines and medical equipment.

Mr. Karlin, associated from 1945 until his retirement in 1977 with Bell Labs, headquartered in Murray Hill, N.J., was widely considered the father of human-factors engineering in American industry.

A branch of industrial psychology that combines experimentation, engineering and product design, human-factors engineering is concerned with easing the awkward, often ill-considered marriage between man and machine. In seeking to design and improve technology based on what its users are mentally capable of, the discipline is the cognitive counterpart of ergonomics.

“Human-factors studies are different from market research and other kinds of studies in that we observe people’s behavior and record it, systematically and without bias,” Mr. Israelski said. “The hallmark of human-factors studies is they involve the actual observation of people doing things.”

Among the issues Mr. Karlin examined as the head of Bell Labs’ Human Factors Engineering department — the first department of its kind at an American company — were the optimal length for a phone cord (a study that involved gentle, successful sabotage) and the means by which rotary calls could be made efficiently after the numbers were moved from inside the finger holes, where they had nestled companionably for years, to the rim outside the dial.

John Elias Karlin was born in Johannesburg on Feb. 28, 1918, and reared nearby in Germiston, where his parents owned a grocery store and tearoom.

He earned a bachelor’s degree in philosophy, psychology and music, and a master’s degree in psychology, both from the University of Cape Town. Throughout his studies he was a violinist in the Cape Town Symphony Orchestra and the Cape Town String Quartet.

Moving to the United States, Mr. Karlin earned a Ph.D. from the University of Chicago in 1942. Afterward, he became a research associate at Harvard; he also studied electrical engineering there and at the Massachusetts Institute of Technology.

At Harvard, Mr. Karlin did research for the United States military on problems in psychoacoustics that were vital to the war effort — studying the ways, for instance, in which a bomber’s engine noise might distract its crew from their duties.

India Ink: Five Questions for: Author and Filmmaker Laleh Khadivi

Laleh Khadivi is an author and filmmaker who was born in Esfahan, Iran, and grew up in California. Her first novel, “The Age of Orphans,” received the Whiting Award for Fiction, the Barnes and Noble Discover New Writers Award and an Emory Fiction Fellowship, and it was translated into eight languages. Her latest novel, “The Walking,” will be published in March. Her debut documentary film, “900 Women,” premiered at the Human Rights Watch Film Festival in 2001. India Ink interviewed Ms. Khadivi at the Jaipur Literature Festival.

What are the occupational hazards of being a writer?

Depression? I’m kidding. I think that when you write, and that is the only thing you do and you don’t have another job you end up spending a lot of time alone in worlds of your creation and so that can make living in the world of reality a little bit difficult. I feel like, for myself and a few other writers I know intimately, going between those two worlds is often very difficult. You don’t have the ease with which to converse randomly at a dinner party when you’ve been writing a torture scene all day. You kind of have to step in and out of the things that you know are fiction and the things that you know to be real. Otherwise, writing is a pretty sweet job. You can’t really complain about it, you know.

What is your everyday writing ritual?

When I’m in the middle of writing a book, doing the day-to-day writing of it, I develop a ritual for that book, but it changes for each book. So I ideally would like to write every morning between 7 a.m. and noon if I can get those many hours –though I just had a son so this is not going to ever happen again. And then from noon until 7, do other things. And then I find the night very useful for writing so I write again from dark until when I go to sleep. At the end of the day, I’m a writer, and in the middle, a regular person.

Why should we read your latest book?

My latest book is about the effects of movies on the imagination. It’s about a lot of other things as well — political things and social things — but mostly it’s about a boy’s love of the cinema and what the cinema does to your desires. How if you only know one world – one particular village or one town – and you watch movies that happen halfway across the globe, how you are changed and how you suddenly think to yourself, “Oh wait, the Earth is bigger than what I know. How do I get to this other place?”

India has such a rich history of cinema, and Bollywood is all about spinning imaginary tales. They might not involve other places on the planet, but they involve other classes, other gender dynamics and other fashion.

It’s a book about that distance between where you are and what you see, and where you can be in cinema and how it changes what you want. It takes place partially in the Kurdish region of Iran and partially in Los Angeles.

How do you deal with your critics?

Ha! I’ve been trying to figure that out.

I think ideally the best way to deal with it is to just not read the reviews. Because with my first book I got these reviews, and some of them were great, and some of them were not. I realized that the ones that were great did not make me feel good — I didn’t celebrate it. And a bad review made me feel terrible. So there was nothing to win, nothing to gain from reading the reviews. Granted, your ego is very tempted to go and see what they are saying about your book, but you know if it’s good and where it’s not good and what the weak parts are.

If someone gives it a bad review and doesn’t like it, there is a good chance they just didn’t get it or it’s not their thing. If I was asked to review a book by John Updike, I would say terrible things, but someone else would give him the Pulitzer Prize. It’s a personal preference. Reviews are very bizarre – they are assigned to one reader and that reader might hate the Middle East. I see the intellectual background of where the reviewer is from – if they do not like Faulkner’s writing, chances are they are not going to like mine.

Why does the Jaipur Literature Festival matter to you?

One billion people – not all of them reading, but still a country of a billion people — you just can’t ignore that. There’s a billion universes going on in those people’s lives and communities, and I feel like because there is an English-speaking presence here and my books can be read without translation, I should go and help people get excited about them.

I have been blown away by the attentiveness and the eagerness of the audiences in Jaipur. I also think that beyond just engaging with readers, I think it’s important to engage with writers about writing and have public discourse about the life of the mind. Our world is increasingly not giving writers and thinkers and artists a place to do that, and so Jaipur is like this small little window to have discussions that are not about money, but about art or politics or inspiration. That’s important to me, and I think that’s important to the increasing readership of Indians.

Illini buzzer-beater upsets No. 1 Hoosiers, 74-72

CHAMPAIGN, Ill. (AP) — Tyler Griffey made the easiest and biggest shot of his career.

The senior forward took an inbounds pass and made a wide-open layup with 0.9 seconds to play to give Illinois a 74-72 victory over No. 1 Indiana on Thursday night, the fifth straight week the nation's top-ranked team lost.

Hoosiers coach Tom Crean, whose team has been No. 1 for a total of seven weeks this season, doesn't have a reason for the recent weekly changes on top of the poll.

"I can't answer that. I'm not sure," Crean said. "I just know that these games are 40-minute games. We played at a high level for most of the game."

The Hoosiers were in charge until the final 3 1-2 minutes when the Illini (16-8, 3-7 Big Ten) finally put together a run to take and then retake the lead.

"I know this, when we turn the ball over we're not very good," Crean said. "And the biggest difference tonight was 28 points off turnovers to our 16."

And nothing could have been worse for the Hoosiers (20-3, 8-2) than the way the game ended.

With 0.9 seconds left Griffey left defenders Cody Zeller and Christian Watford behind on an inbounds play from the baseline, took the pass from Brandon Paul and delivered the uncontested buzzer-beater for the Illini.

The shot sent hundreds of students onto the court — holding their collective breath as officials checked the replay to make sure the clock hadn't beaten Griffey — and Paul and fellow guard D.J. Richardson hugged and teared up with relief.

Illinois had lost eight of 11 since starting the season 12-0. The Illini had been ranked as high as No. 10 and were now falling to the bottom of the Big Ten.

Griffey, accustomed to struggling in recent weeks, seemed surprised with the ease he was able to make the game-winner.

"I just made a simple curl cut and left two guys behind me, and Brandon got off a heck of a pass," he said. "Zeller and Watford were both right in front of me and just kind of stayed there."

Crean, whose team just moved into the No. 1 spot after knocking off then-No. 1 Michigan on Saturday, said the play was a lot like the other breakdowns in the Hoosiers' game that let Illinois climb back from a 12-point halftime deficit.

"We didn't communicate," Crean said.

"They're very deserving of the win, they never gave in," he added, but he qualified that with, "We didn't put them away when we had the opportunities."

Indiana's loss drops them into a three-way tie for first in the Big Ten with Michigan and Michigan State. For the Illini, the win means a move out of 10th in the 12-team conference up into a ninth-place tie with Iowa.

More importantly, it's a potential lifeline for an Illini team that still has to face No. 18 Minnesota on the road Sunday and had been watching its season slip away.

"It was good to get back to having that toughness and togetherness and trust that we needed," Illinois coach John Groce said.

Illinois hadn't beaten a No. 1 team since a 2004 win over Wake Forest. But the Illini had won nine of the last 10 against the Hoosiers in Champaign. And this season, whatever else has gone wrong, Illinois has delivered against the big boys. Coming into Thursday night the Illini had already beaten three teams now in the top 15: No. 6 Gonzaga, No. 10 Ohio State and No. 14 Butler.

Richardson had 23 points for Illinois, Paul had 21 and Griffey finished with 14 points and eight rebounds.

Zeller led Indiana with 14 points, while Will Sheehey had 13, Watford 12 and Jordan Hulls 11.

Indiana shot 50 percent from the field (25 of 50), 52.9 percent from 3-point range (9 of 17) and 93 percent from the free throw line (13 of 14). The Hoosiers led by an 8- to 10-point margin for most of the second half.

And when 6-foot-11 Nnanna Egwu fouled out with just under 5 minutes to play, Indiana looked in control. Egwu is the only Illini player with the size to realistically match up with the 7-0 Zeller.

Watford made two free throws after Egwu's fifth foul and, at 69-59, the Illini looked done.

But with the clock under 3 minutes, Richardson went on a run of his own, first burying consecutive 3-pointers and then hitting a midrange jumper on the run to tie the game at 70 with 1:17 to play.

Oladipo's layup put the Hoosiers back on top with 50 seconds left, but Paul answered with two free throws, the first banked in, to tie the score again at 72.

With the clock under 30 seconds, Indiana had the ball for what would have been a last shot but Oladipo fumbled the ball. Richardson picked it up and sprinted down court. Oladipo slapped Richardson's layup out of bounds to set up the final play.

Groce credited Richardson for sparking the comeback.

"I thought he was absolutely terrific on both ends of the floor," Groce said. "He battled, he fought."

Griffey was benched several weeks ago after a blowout loss at Wisconsin. On a team that had lost its shooting touch, the senior forward had grown especially cold. And, though one of Illinois' bigger players at 6-9, he wasn't adding much to the inside presence the Illini desperately needed.

The play that brought him to life Thursday, though, had nothing to do with Illinois' late surge. Griffey hit a 3-pointer less than 4 minutes into the second half. He had missed 20 straight 3-point attempts, dating to the start of the Big Ten season.

"I said to myself, 'Finally,'" said Griffey, who said he has been doing so much extra shooting that he's had to have regular ice treatments on his wrist.

Groce said that, even after he benched Griffey, he never gave up on him.

"I just have told him numerous times here I believe in him," the first-year Illinois coach said. "I do."

Well: Old Age and Motorcycles Are a Dangerous Mix

If you’re over 40 and planning to hop on a motorcycle, take care. Compared with younger riders, the odds of being seriously injured are high.

That is the message of a new study, published this week in the journal Injury Prevention, which found that older bikers are three times as likely to be severely injured in a crash as younger riders.

The percentage of older bikers on the road is quickly rising, and their involvement in accidents is a growing concern. Nationwide, from 1990 to 2003, the percentage of motorcyclists over age 50 soared from roughly 1 in 10 to about 1 in 4. At the same time, the average age of riders involved in motorcycle crashes has also been climbing. Injury rates among those 65 and older jumped 145 percent from 2000 to 2006 alone.

Because of the increase in motorcycle ridership among older Americans, the researchers, led by Tracy Jackson, a graduate student in the epidemiology department at Brown University, wanted a closer look at their injury patterns. So she and her colleagues combed through a federal database of motorcycle crashes that were serious enough to require emergency medical care. That yielded about 1.5 million incidents involving motorcyclists 20 or older from 2001 to 2008.

The researchers then split them into groups: those in their 20s and 30s, another group between 40 and 59, and those 60 and older.

Over all, the study showed that injury rates for all three groups were on the rise. But the rise was steepest for the oldest riders. Compared with the youngest motorcyclists, those who were 60 and older were two and a half times as likely to end up with serious injuries, and three times as likely to be admitted to a hospital. The riders who were middle age were twice as likely as their younger counterparts to be hospitalized.

For older riders, the consequences of a collision were also especially alarming. Older and middle-aged bikers were more likely to sustain fractures and dislocations, and they had a far greater chance of ending up with injuries to internal organs, including brain damage.

The researchers speculated that it was very likely that a number of factors played a role in older riders’ higher injury rates. For one, declines in vision and reaction time may make older riders more prone to mistakes that end up in collisions. Another theory is that older riders tend to ride bigger bikes, “which may be more likely to roll or turn over,” Ms. Jackson said.

Then there is the greater fragility that comes with age. Older riders may be involved in the same types of accidents as younger riders, Ms. Jackson said, but in some cases, a collision that a 20-year-old would walk away from might send a 65-year-old to the hospital.

“Your bones become more brittle, and you lose muscle mass as you get older,” she said. “It could just be a matter of aging and the body being less durable.”

European Leaders Struggle to Bridge Budget Gaps

BRUSSELS — European Union leaders on Friday morning edged closer to agreeing a budget worth nearly €1 trillion, or $1.3 trillion, to support farming, transportation and other infrastructure, as well as big research projects for the 27-nation bloc.

But after 15 hours of talks, the leaders were still seeking unanimity while also attempting to satisfy the wide array of national interests demanding attention.

The budget is negotiated every seven years and involves furious horse-trading as leaders focus on getting the best deal for their own countries’ citizens, rather than emphasizing pan-European considerations.

The marathon session was the second attempt to reach a deal on the funding package, which should run from 2014 to 2020, after the first attempt collapsed in November.

Another failure to strike a deal on a sum of money that represents only about 1 percent of the Union’s Gross Domestic Product would be a severe embarrassment for the leaders, who already have spent years bickering over how to save the euro.

The European Commission, the bloc’s policymaking arm, had sought an increase in the overall budget of around 5 percent to more than €1 trillion.

Herman Van Rompuy, the president of the European Council, which represents E.U. leaders, pruned that sum to about €973 billion at the previous summit in November.

On Friday morning, Mr. Van Rompuy presented further revisions lowering the overall sum to about €960 billion but holding down the amount of cash governments pay up-front to around €908 billion.

That formula was designed, in part, to satisfy countries like Britain and the Netherlands that pay more into the budget than they receive, while also accommodating the demands of countries like France and Italy that want to maintain generous payments for agriculture and infrastructure.

Some of the deepest cuts would be made to pan-European projects to improve transport, energy, and digital services that are overseen by the commission. About €1 billion in cuts would be made to the part of the budget used to employ 55,000 people, including 6,000 translators, most of them in Brussels, who run the Union’s day-to-day affairs.

Expert national advisors were reviewing the proposals on Friday morning, and leaders were expected to reconvene for further talks.

Leaders also were wrestling over demands by some countries to renew a system of rebates that raises the costs for other countries.

One of the complications in the current round of negotiations has been the call for budgetary rigor from leaders like David Cameron, the British prime minister, who says the Union should tighten its belt at a time when many European governments have been compelled to impose stringent budget cuts.

Mr. Cameron, in particular, has earned the enmity of some European leaders by demanding a renegotiation of Britain’s treaty with the Union and promised a referendum on his nation’s membership in 2017.

Reflecting growing irritation with Britain among a number of European leaders, Martin Schulz, the president of the European Parliament, told a news conference late on Thursday night that leaders should not go out of their way to appease Mr. Cameron.

Because Britain could be outside the bloc by later this decade, there was little need to make concessions to Mr. Cameron that potentially jeopardized “the security of our financial planning,” Mr. Schulz suggested.

Mr. Van Rompuy, the president of the European Council, had intended to start the session during the mid-afternoon on Thursday to force leaders to make their complaints clear in a roundtable session rather than being allowed to break into small groups.

But his plan was derailed, and the first roundtable session was delayed until late in the evening, as leaders formed the kind of pre-summit huddles that he seemingly wanted to avoid.

President François Hollande of France was an hour late to a meeting during the afternoon with Mr. Cameron, Angela Merkel, the German chancellor, and Mr. Van Rompuy.

Mr. Hollande’s lateness was a sign of French displeasure with British demands that included strict limits on agriculture spending cherished by French farmers, according to an E.U. diplomat, who spoke on condition of anonymity because of the sensitivity of the talks.

Even if leaders eventually agree to a deal, it faces still more hurdles before it becomes law at the European Parliament, which has the power to veto the budget.

Some of the most influential figures in Parliament have already signaled that they are prepared to reject a budget that foresees spending less on Europe in the years ahead.

Guy Verhofstadt, the head of the alliance of liberals in the Parliament, called on Thursday for a full-revision clause to be inserted into the budget, so that it could be increased after three years if economic conditions improved.

Mr. Schulz, the president of the Parliament, said on Thursday that he would not approve a budget that ended up widening the overall gap between the amount of cash paid up-front by governments and the somewhat higher amounts known as commitments, which make up the overall budget.

IHT Rendezvous: 'Rigoletto' in Vegas, 'Manon Lescaut' in the Metro

BRUSSELS—The day after the Metropolitan Opera in New York unveiled a production of Verdi’s “Rigoletto” set in Las Vegas during the 1960s, I was in Belgium, where another exercise in operatic updating is underway at the Théâtre royal de la Monnaie. Here, Mariusz Trelinski’s staging of Puccini’s “Manon Lescaut” — through Feb. 8 — situates the opera in the waiting room of a subway station.

Opera goers are often incensed by productions like these, yet updating is potentially a relatively mild device. Once the new setting is established, the action can play out coherently and essentially traditionally. This happened with “La Bohème” last summer at the Salzburg Festival, staged by Damiano Michieletto.

One could object to the hovel of the bohemians’ Parisian loft, but there was something touching about seeing Anna Netrebko as Mimì crouched in the snow behind a hotdog truck near the city’s peripheral expressway, as she overheard Rodolfo and Marcello discussing her fragile health.

By contrast, La Scala’s recent “Lohengrin” directed by Claus Guth, which focused on the repressiveness of German society at the time of the opera’s composition and, in Mr. Guth’s fanciful interpretation, its bizarre effects on the psyche of the title character, counts as truly radical.

The Met’s take on “Rigoletto” had a widely acknowledged antecedent in Jonathan Miller’s production of the opera for the English National Opera, which was set in New York’s Little Italy and seen in that city on a 1984 tour. The Met’s new production by Michael Mayer is reportedly less successful. Writing in The New York Times, Anthony Tommasini detected “dynamic elements in this colorful, if muddled and ill-defined ‘Rigoletto’” but noted that “there are big holes” in Mr. Mayer’s concept. The criticism is directed not so much at the updating itself but the lack of disciplined follow-through.

The updating of “Manon Lescaut,” which is specified to take place in the 18th century, comes off as inherently misguided. Boris Kudlicka’s chic-looking set is essentially all in black, although city lights are sometimes visible, as if seen from a moving train. A system map is on one wall, pay telephones on another.

The mismatch is apparent from the first measures of Puccini’s sparkling orchestral introduction to Act 1. This is music designed for the outdoors—a public square in Amiens—not a space underground. It announces something special is in the works, not dreary routine. It conveys youthful high spirits, not gloom. Also, the mores of pre-revolutionary France are important in the opera.

Whether Mr. Trelinski’s conception of Manon herself is an outgrowth of his updating, or the other way around, it robs her of her allure. When, early on, the smitten Des Grieux declares his love for her, Manon sits at the end of a bar wearing a red coat and dark glasses and smoking a cigarette—the very image of a prostitute. Manon is a material girl all right, but one with such irresistible femininity she gets what she wants from men without having to market herself. You never sense this here. Further, a demimonde element weighs on the first two acts. Manon’s benefactor, Geronte (the bass Giovanni Furlanetto, in excellent voice), is depicted as a crime figure, and there is some curious activity involving topless girls and golf clubs.

Mr. Trelinski’s approach also intensifies an acknowledged structural weakness of the opera. All the opera’s gaiety is concentrated in the first two acts, whereas Act 3 and 4—in which Manon is deported from France and then dies in the New World—are uniformly gloomy. But here, Acts 1 and 2 are gloomy too.

Mr. Trelinski, who is artistic director of the Teatr Wielki in Warsaw, where the production originated, is a respected director with some notable achievements. I have admired his double bill of Bartok’s “Bluebeard’s Castle” and Tchaikovsky’s “Iolanta,” which will be seen at the Met in a future season. His work here has some redeeming aspects, especially in Act 4. Puccini’s setting for this act—a vast desert near the outskirts of New Orleans—is one of opera’s most implausible, so it is no great loss to see it supplanted. Fascinatingly, Mr. Trelinski ensures that Des Grieux suffers here as much as Manon does, as he becomes delusional and, apparently, starts to see double. A second Manon appears, whom Des Grieux cannot seem to distinguish from the first.

Carlo Rizzi presides over a colorful reading of the score and a cast headed by an excellent pair of lovers in Eva-Maria Westbroek and Brandon Jovanovich. When the two sang their big duet in Act 2, you could forget about the production and become wrapped up in Puccini’s drama. Ms. Westbroek’s commanding soprano is a bit large for Manon, whose music can profit from greater tonal delicacy. Still, she offers some splendid singing, apart from some difficulty on top, and gives an especially gripping account of Manon’s final aria, “Solo, perduta, abbandonata.”

In this production Des Grieux emerges as the more emotionally vibrant lover, and Mr. Janovich’s clear, virile singing makes the most of the opportunity. Unfortunately, he was in ill health and departed the performance after Act 2, but the intervention of Hector Sandoval, the alternate Des Grieux, allowed the performance, which was streamed to movie theaters, to continue without a hitch. He sang well and knew intricacies of the staging, flaws and all.
