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.”

Lens Blog: Sirkka-Liisa Konttinen's Photos of Her Newcastle Neighborhood

On clear days in Newcastle-Upon-Tyne, a small yet bustling working-class city in northeast England, the view from the hills of Byker can be spectacular. That shabby neighborhood’s rows of brick houses and terraced streets overlook a historic city center, the river and sometimes far beyond.

Those vistas were rare in 1969, when Sirkka-Liisa Konttinen, a 21-year-old Finnish photographer, arrived. The landscape was cloaked in an industrial fog belched from the coal and shipbuilding industries.

Despite the grayness, the laughter and vivacity that radiated from this close-knit community appealed to Ms. Konttinen. It welcomed a young foreigner whose presence stoked curiosity, but also generosity. They joked with her in pubs. Some of the older women took her under their wing — she kindled a protective instinct in them.

“People were baffled by my choice to live there,” Ms. Konttinen recalled. “Not that many people had any idea where Finland was, but if they did, they thought it such a beautiful clean country, and why would I choose to come to Byker?”

She had ventured there because of Amber Collective, a progressive documentary project that she helped found, which chronicled the lives of working people in northeast England. The group was formed in London by a handful of students who made a film following Vietnam War demonstrations at Grosvenor Square that turned violent. Titled “All You Need Is Dynamite,” it was just a student effort, but its makers found they shared a philosophy.

Before long, they had relocated to Newcastle.

The city was in decline. Urban planners sought flashy new development projects, and some sections, like Byker, were scheduled for demolition. Ms. Konttinen was unaware that she was documenting a place that was about to disappear. Not drawn to gloomy topics, she found the place spirited and interesting.

“Initially, I don’t think we ever thought that we need to document it because it will be the only thing left for people to remember the place and what the area was like,” she said. “I personally have never felt that that was my mission.”

The Amber Collective has produced an enormous amount of material, dating back decades, that is focused on the communities of northeast England, although Ms. Konttinen’s Byker pictures are probably the collective’s best-known project. That work was published as a book in 1983; Amber also released a film companion of the same name, and in 2011 her documentation was registered with the Unesco U.K. Memory of the World. For the first time in a commercial art space, photographs from the series will be shown in the United States, on view at the L. Parker Stephenson Gallery from Feb. 15 through May 11. Ms. Konttinen will also deliver a lecture at the International Center for Photography on Feb. 13.

In recent years, she returned to Byker. The new Byker is changed — more on that Friday — and the changes required her to reconsider her approach when she decided to photograph it. The newer project, “Byker Revisited,” is a result of a far more collaborative endeavor. Not that she hadn’t collaborated in other ways with a subject before. Her 1971 photo of Heather (Slide 3) brought about one such relationship.

“I heard music coming from a derelict house,” she said. “This was one of the last terraces before the final demolition, and there were no steps left to the house, but upstairs I heard music, piano, coming out the windows.”

She entered the house, climbing a rickety staircase to where the music was coming from. She found a girl, Heather, “playing the piano, banging the notes that were kind of stuck and unstuck.”

Ms. Konttinen and Heather started talking, and Ms. Konttinen taught her a simple tune.

“I told her if she ever wanted to come and play, she could come and play it again on my piano,” Ms. Konttinen said. Heather showed up a few days later, with her little brother. On Ms. Konttinen’s piano, they played the tune together.

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."

Chinese Imports and Exports Soar in January

HONG KONG — January trade data from China on Friday showed a surge in exports and imports from a year earlier — a phenomenon that was largely due to the timing of the Lunar New Year holiday, but that also supported the view that the Chinese economy is firming.

Economic data from China are often severely distorted by the holiday, the highlight of the Chinese calendar, when many factories shut down for a week or more.

The holiday this year takes place in February — the first day of the Lunar New Year is on Sunday — but last year it fell squarely in January, cutting down on the number of working days during that month.

The trade data released Friday reflected this with a large increase compared with the year before, as analysts had expected. Exports climbed 25 percent from January 2012, according to the General Administration of Customs, and imports soared 28.8 percent.

Both figures beating expectations by a wide margin, however, supported the view that the rise was also caused in part by healthier domestic and overseas demand.

“This strong export number cannot be fully explained by the Chinese New Year effect alone,” Zhiwei Zhang, chief China economist at Nomura in Hong Kong, said in a research note.

“These data suggest that external and domestic demand are both strong, which supports our view that the economy is on track for a cyclical recovery” in the first half of this year, he added.

Dariusz Kowalcyk, an economist at Crédit Agricole in Hong Kong, said “we need to wait for February results to have the full picture of trade at the start of 2013.”

However, he added, “one trend is clear: exports have been doing very well recently. This may be a sign of improved external demand, but is also a testimony to the resilience of Chinese exporters and to their competitiveness.”

The Chinese economy has been accelerating gradually in the past few months, reversing a marked slowdown that had raised fears of a possible “hard landing” in China early last year.

Improved overseas demand, combined with a string of government-mandated stimulus measures, have gradually propped up growth and dispelled those fears.

Data released last month showed the Chinese economy expanded just 7.8 percent last year — down from 9.3 percent in 2011 and 10.4 percent in 2010 — but many analysts expect slightly faster growth again in 2013.

Well: Think Like a Doctor: A Confused and Terrified Patient

The Challenge: Can you solve the mystery of a middle-aged man recovering from a serious illness who suddenly becomes frightened and confused?

Every month the Diagnosis column of The New York Times Magazine asks Well readers to sift through a difficult case and solve a diagnostic riddle. Below you will find a summary of a case involving a 55-year-old man well on his way to recovering from a series of illnesses when he suddenly becomes confused and paranoid. I will provide you with the main medical notes, labs and imaging results available to the doctor who made the diagnosis.

The first reader to figure out this case will get a signed copy of my book, “Every Patient Tells a Story,” along with the satisfaction of knowing you solved a case of Sherlockian complexity. Good luck.

The Presenting Problem:

A 55-year-old man who is recovering from a devastating injury in a rehabilitation facility suddenly becomes confused, frightened and paranoid.

The Patient’s Story:

The patient, who was recovering from a terrible injury and was too weak to walk, had been found on the floor of his room at the extended care facility, raving that there were people out to get him. He was taken to the emergency room at the Waterbury Hospital in Connecticut, where he was diagnosed with a urinary tract infection and admitted to the hospital for treatment. Doctors thought his delirium was caused by the infection, but after 24 hours, despite receiving the appropriate antibiotics, the patient remained disoriented and frightened.

A Sister’s Visit:

The man’s sister came to visit him on his second day in the hospital. As she walked into the room she was immediately struck by her brother’s distress.

“Get me out of here!” the man shouted from his hospital bed. “They are coming to get me. I gotta get out of here!”

His blue eyes darted from side to side as if searching for his would-be attackers. His arms and legs shook with fear. He looked terrified.

For the past few months, the man had been in and out of the hospital, but he had been getting better — at least he had been improving the last time his sister saw him, the week before. She hurried into the bustling hallway and found a nurse. “What the hell is going on with my brother?” she demanded.

A Long Series of Illnesses:

Three months earlier, the patient had been admitted to that same hospital with delirium tremens. After years of alcohol abuse, he had suddenly stopped drinking a couple of days before, and his body was wracked by the sudden loss of the chemical he had become addicted to. He’d spent an entire week in the hospital but finally recovered. He was sent home, but he didn’t stay there for long.

The following week, when his sister hadn’t heard from him for a couple of days, she forced her way into his home. There she found him, unconscious, in the basement, at the bottom of his staircase. He had fallen, and it looked as if he may have been there for two, possibly three, days. He was close to death. Indeed, in the ambulance on the way to the hospital, his heart had stopped. Rapid action by the E.M.T.’s brought his heart back to life, and he made it to the hospital.

There the extent of the damage became clear. The man’s kidneys had stopped working, and his body chemistry was completely out of whack. He had a severe concussion. And he’d had a heart attack.

He remained in the intensive care unit for nearly three weeks, and in the hospital another two weeks. Even after these weeks of care and recovery, the toll of his injury was terrible. His kidneys were not working, so he required dialysis three times a week. He had needed a machine to help him breathe for so long that he now had to get oxygen through a hole that had been cut into his throat. His arms and legs were so weak that he could not even lift them, and because he was unable even to swallow, he had to be fed through a tube that went directly into his stomach.

Finally, after five weeks in the hospital, he was well enough to be moved to a short-term rehabilitation hospital to complete the long road to recovery. But he was still far from healthy. The laughing, swaggering, Harley-riding man his sister had known until that terrible fall seemed a distant memory, though she saw that he was slowly getting better. He had even started to smile and make jokes. He was confident, he had told her, that with a lot of hard work he could get back to normal. So was she; she knew he was tough.

Back to the Hospital:

The patient had been at the rehab facility for just over two weeks when the staff noticed a sudden change in him. He had stopped smiling and was no longer making jokes. Instead, he talked about people that no one else could see. And he was worried that they wanted to harm him. When he remained confused for a second day, they sent him to the emergency room.

You can see the records from that E.R. visit here.

The man told the E.R. doctor that he knew he was having hallucinations. He thought they had started when he had begun taking a pill to help him sleep a couple of days earlier. It seemed a reasonable explanation, since the medication was known to cause delirium in some people. The hospital psychiatrist took him off that medication and sent him back to rehab that evening with a different sleeping pill.

Back to the Hospital, Again:

Two days later, the patient was back in the emergency room. He was still seeing things that weren’t there, but now he was quite confused as well. He knew his name but couldn’t remember what day or month it was, or even what year. And he had no idea where he was, or where he had just come from.

When the medical team saw the patient after he had been admitted, he was unable to provide any useful medical history. His medical records outlined his earlier hospitalizations, and records from the nursing home filled in additional details. The patient had a history of high blood pressure, depression and alcoholism. He was on a long list of medications. And he had been confused for the past several days.

On examination, he had no fever, although a couple of hours earlier his temperature had been 100.0 degrees. His heart was racing, and his blood pressure was sky high. His arms and legs were weak and swollen. His legs were shaking, and his reflexes were very brisk. Indeed, when his ankle was flexed suddenly, it continued to jerk back and forth on its own three or four times before stopping, a phenomenon known as clonus.

His labs were unchanged from the previous visit except for his urine, which showed signs of a serious infection. A CT scan of the brain was unremarkable, as was a chest X-ray. He was started on an intravenous antibiotic to treat the infection. The thinking was that perhaps the infection was causing the patient’s confusion.

You can see the notes from that second hospital visit here.

His sister had come to visit him the next day, when he was as confused as he had ever been. He was now trembling all over and looked scared to death, terrified. He was certain he was being pursued.

That is when she confronted the nurse, demanding to know what was going on with her brother. The nurse didn’t know. No one did. His urinary tract infection was being treated with antibiotics, but he continued to have a rapid heart rate and elevated blood pressure, along with terrifying hallucinations.

Solving the Mystery:

Can you figure out why this man was so confused and tremulous? I have provided you with all the data available to the doctor who made the diagnosis. The case is not easy — that is why it is here. I’ll post the answer on Friday.

Japan Spends Heavily to Keep Whaling Industry Afloat, Report Says

TOKYO — A wildlife conservation group said in a report on Wednesday that Japan has been propping up its whaling industry with nearly $400 million in tax money in recent years, stepping up subsidies even as consumption of whale meat here has slumped.

The report, compiled by the International Fund for Animal Welfare, in Yarmouth Port, Mass., challenges assertions by the Japanese government that whaling is a tradition with wide support among Japanese consumers.

Instead, government figures tallied in the report paint a picture of a struggling industry employing fewer than 1,000 people and dependent on public handouts, including money meant for reconstruction after the devastating earthquake and tsunami of March 2011.

Most Japanese consumers have turned away from whale meat. The industry shipped just 5,000 tons in 2011, compared with 233,000 tons at the peak in 1962, according to data from the Ministry of Agriculture, Forestry and Fisheries. Demand this year is so low that the industry has cut its planned shipments by half, to 2,400 tons.

“Whaling is unprofitable, and survives only with substantial subsidies, something cultural and nationalist arguments for whaling obscure,” said Patrick Ramage, the director of the animal welfare fund’s whale program. He said the country would be better off economically and ecologically if it promoted whale-watching tourism instead of hunting whales.

Japan’s Fisheries Agency declined to comment on the report, saying it had not yet studied its contents.

But an official, speaking on the condition of anonymity, said there was “nothing wrong with these subsidies, which fund an important program,” though it was “not the government’s responsibility to make whaling economically viable.”

A world moratorium on commercial whaling took effect in 1986, but Japan has taken advantage of an exception allowing whaling for research purposes to continue hunting, though environmental activists who chase whaling boats have made those hunts increasingly difficult. Japan has captured and killed more than 14,000 whales since the moratorium began.

The meat from the whales is sold off as “byproducts” of research, and it makes its way to supermarkets, restaurants and even school lunches. A government Web site says the most popular whale dishes are fried whale, whale sashimi and medium-rare whale steak.

According to figures from the Institute of Cetacean Research, the nonprofit organization set up to run the whaling program, income from whale meat has failed to cover the costs of whaling for the past five years. So subsidies have been increased, and some disaster aid has been diverted to the industry, prompting a public outcry.

The dire financial picture prompted the government to announce a plan last year to cut costs by reducing the annual catch and to sell more whale meat directly to schools for lunches. But experts doubt that those measures will make the whaling industry self-sufficient again. 

“The Japanese government has desperately defended whaling for years, but the question has increasingly become: for what?” said Yusuke Saskata, a professor of environmental economics at Kinki University in Osaka. “Supporting whaling culture is one thing, but maintaining whaling at this scale makes no sense.”

Signing Day: Ole Miss muscles in on power programs

Alabama. Ohio State. Michigan. Florida. Notre Dame. Mississippi?

Ole Miss muscled in on the powerhouses that usually dominate national signing day, landing some of the most sought-after prospects in the country on college football's annual first-Wednesday-in-February frenzy.

The Rebels, coming off a promising 7-6 season in their first season under coach Hugh Freeze, had the experts swooning by signing three of the bluest chips still on the board and building a well-rounded class otherwise.

"I do think (this class) has the possibility of being a program changer," Freeze said. "But it's all on paper right now.

The day started with defensive end Robert Nkemdiche from Loganville, Ga., rated the No. 1 recruit in the country by just about everyone who ranks them, deciding to join his brother, Denzel, in Oxford, Miss.

"I feel like it's the right place for me," Nkemdiche said after slipping on a red Ole Miss cap. "I feel like they can do special things and they're on the rise. I feel like going to play with my brother, we can do something special."

Nkemdiche originally committed to Clemson last year, then backed off that and narrowed his picks down to LSU, Florida and Mississippi — and the Rebels beat the big boys.

They weren't done. Coaches in the Ole Miss war room were exchanging hugs and high-fives again a couple hours later when Laremy Tunsil, a top-rated offensive tackle from Lake City, Fla., picked the Rebels over Florida State and Georgia.

"Tunsil to Ole Miss I think was the biggest surprise of the whole (recruiting season)," said JC Shurburtt, national recruiting director for 247Sports.com.

And, as if the Ole Miss needed more good news, highly touted defensive back Antonio Conner from nearby Batesville, Miss., chose the Rebels over national champion Alabama.

Ole Miss also landed Laquon Treadwell from Crete, Ill., one of the best receiver prospects in the country. He made a verbal commitment to the Rebels back in December, and sealed the deal Wednesday, the first day high school players can sign binding letters of intent.

The end result was a class good enough to even catch the attention of LeBron James.

"Ole Miss ain't messing around today! Big time recruits coming in. SEC is crazy," the NBA MVP posted on his Twitter account.

Crazy good. While the Rebels racked up, it's important to remember they still have plenty of ground to gain on the rest of their conference.

Nick Saban reloaded the Crimson Tide with a class that Rivals.com ranked No. 1 in the country.

SEC powers Florida, LSU and Georgia pulled in typically impressive classes. SEC newcomer Texas A&M cracked the top 10 of several rankings. Even Vanderbilt, coming off a nine-win season, broke into the top 25.

It's the cycle of life in the SEC, which has won seven straight BCS championships. Stock up on signing day and scoop up those crystal footballs at season's end.

SLIPPING AWAY FROM USC

Signing day didn't do much to soothe the scars left from a difficult season for Southern California.

NCAA sanctions limited the number of scholarships coach Lane Kiffin and the Trojans could hand out this year, and then as signing day approached USC had several players who had given verbal commitments change their minds.

The most notable defection on signing day was five-star defensive back Jalen Ramsey of Brentwood, Tenn., who flipped to Florida State. Defensive end Jason Hatcher from Louisville, Ky., bailed on USC and signed with Kentucky, and defensive end Torrodney Prevot from Houston not only reneged on his USC commitment, but he landed at Pac-12-rival Oregon.

"People expected (Prevot) to flip from USC, but they thought it would be to Texas A&M," Shurburtt said.

USC's class won't be lacking blue chippers. Quarterback Max Browne from Washington is considered the next in a long line of topflight Trojans quarterbacks, and Kenny Bigelow from Maryland is rated among the best defensive linemen in the nation.

Kiffin will be banking on quality to make up for the lack of quantity, but that's a precarious way to play a game as uncertain as recruiting.

IF MOMMA'S NOT HAPPY ...

Alex Collins, a top running back prospect out of Plantation, Fla., announced on Monday night that he was going to Arkansas instead of Miami.

It was considered a huge victory for new Razorbacks coach Bret Bielema.

But on Wednesday morning, when it was time to make it official, Collins' letter of intent didn't come spinning through the fax machine in Fayetteville, Ark.

There were some odd reports about Collins' mother not being happy with her son's decision to go so far from home.

College coaches aren't allowed to talk about specific players before they sign, but Bielema did acknowledge during his signing day news conference that Arkansas' class of 22 players could "grow by one."

___

THE BIG TWO

Ohio State and Michigan received two thumbs up from experts on their signing day classes. They all had the Buckeyes and Wolverines around top five in the country.

After that, there was a drop off. Nebraska received solid grades and Penn State, despite NCAA sanctions that limited its class to 17 signees, held up pretty well.

"That's a tribute to the job (Penn State coach) Bill O'Brien and the staff did," Shurburtt said.

But signing day 2013 signaled that Urban Meyer's Buckeyes and Brady Hoke's Wolverines are primed to pull away from most of the Big Ten, and maybe — just maybe — give the league a team or two that can challenge those SEC teams for a national title.

___

BUILT TO LAST

Notre Dame followed up its best season in more than two decades with a recruiting class that coach Brian Kelly hopes can keep the Fighting Irish contending for more national titles.

The class includes a famous name in Torii Hunter Jr., the son of the All-Star outfielder. Hunter Jr. is a top-notch receiver prospect, though he broke his leg during an All-Star game and it could be a while before he's back on the football field.

Linebacker Jaylon Smith from Fort Wayne, Ind., is generally regarded as the jewel of a class that experts have ranked among the best in the country.

"I love agreeing with experts," Kelly said.

___

BASEBALL OR FOOTBALL?

Oklahoma hopes it has found the next Sam Bradford in Cody Thomas, a pocket passer from Colleyville, Texas.

One small problem. Thomas is also a big-time baseball player who could draw interest in the major league draft this summer.

"We wouldn't have pursued him if we didn't feel there was a great chance he'd be playing football," Oklahoma coach Bob Stoops said.

___

QUOTABLE

South Carolina coach Steve Spurrier said recruiting classes "don't always pan out. Of course, they always seem to pan out at Alabama."

DealBook: R.B.S. to Pay $612 Million Over Rate Rigging

A campaign to root out financial fraud secured a victory on Wednesday, as authorities took aim at the Royal Bank of Scotland for its role in an interest rate manipulation scheme that has emboldened prosecutors and consumed the banking industry.

American and British authorities struck a combined $612 million settlement with the bank, the latest case to emerge from the global investigation into rate-rigging. The Justice Department dealt another blow to the bank, forcing its Japanese unit to plead guilty to criminal wrongdoing.

The penalty for the subsidiary, a hub of rate manipulation, underscores a recent shift in the way federal authorities punish financial wrongdoing. The R.B.S. case echoed an earlier action taken against a UBS subsidiary, which similarly pleaded guilty to felony wire fraud as part of a larger settlement. These cases represent the first units of a big bank to agree to criminal charges in more than a decade.

“I want financial institutions to know that this department will absolutely hold them to account,” Lanny Breuer, head of the Justice Department’s criminal division, said in an interview Wednesday.

Some of the world’s largest financial institutions remain caught in the cross hairs of the rate manipulation case, an investigation that could drag on for years. Authorities suspect that more than a dozen banks falsified reports to influence benchmarks like the London Interbank Offered Rate, or Libor, which underpins the costs for trillions of dollars in financial products like mortgages and credit cards.

A person involved in the investigation indicated that the first banks to settle were among the worst actors in the rate case. But they also received a “discount” for their eager cooperation, according to people with knowledge of the matter.

That approach raises the prospect that remaining banks could face high-priced settlements.

Deutsche Bank, which set aside an undisclosed amount to cover potential penalties and suspended five employees tied to the case, is expected to settle with authorities in late 2013, several people briefed on the matter said. But the timetable could shift. The bank is not in formal settlement talks and is not prepared to resolve the case, the people said.

While foreign banks have borne the brunt of the scrutiny, an American institution could be among the next to settle. Citigroup and JPMorgan Chase are under investigation by the Commodity Futures Trading Commission, the American regulator leading the case, though actions are not imminent.

The R.B.S. action concluded a first phase of rate-rigging investigations for authorities, who are now planning to take a brief hiatus from filing cases. The next case is not expected until spring at the earliest, two of the people briefed on the matter said.

Some bank executives, fearful that fallout from the case will stain their firms, are pushing for a broad deal encompassing multiple institutions. But authorities are balking at a “global settlement,” people involved in the case say, arguing that investigations are proceeding at different stages and involve widely varying fact patterns.

As regulators continue to pursue actions, prosecutors are planning charges against traders involved in the scheme. The first charges came last year when the Justice Department filed actions against two former UBS traders.

“Our investigation is far from finished,” Mr. Breuer said.

The rate-rigging case has centered on how much banks charge each other for loans. Such figures form the basis of Libor and other rates. But banks corrupted the process. Government complaints filed over the last year outlined a scheme in which banks reported false rates to lift trading profits.

Authorities announced the first Libor case in June, extracting a $450 million settlement with the British bank Barclays. In December, UBS agreed to a record $1.5 billion settlement with authorities. The Justice Department also secured the guilty plea from one of the bank’s subsidiaries.

Royal Bank of Scotland, based in Edinburgh, had aimed to avert the guilty plea for its Japanese subsidiary, people involved in the case said. But the Justice Department’s criminal division declined to back down, and the bank had little leverage to push back. It decided not to formally appeal its case to Attorney General Eric H. Holder Jr., another person said.

With fines coming from multiple authorities, the $612 million case amounted to the second-largest penalty levied in the multiyear investigation into rate manipulation. “The settlement with R.B.S. is much more than a slap on the wrist,” argued Bart Chilton, a member of the trading commission who is critical of soft fines on big banks.

The settlement represents the latest setback for Royal Bank of Scotland, which has struggled to shake the legacy of the 2008 financial crisis. The British firm, which is majority-owned by the government after a bailout, already has put aside $2.7 billion to compensate customers who were inappropriately sold loan insurance in recent years.

Since the financial crisis, the bank has shaken up its management team and refocused its operations, as part of an effort to repair its bruised image. On Wednesday, it announced plans to claw back bonuses to help pay for the latest settlement.

At a news conference in London on Wednesday, Stephen Hester, the bank’s chief executive, admitted that the rate-rigging episode significantly strained the bank. “It is one of the most difficult moments over the entire period,” he said.

As authorities stitched together the R.B.S. case, they seized on a series of colorful e-mails that highlighted an effort to influence the rate-setting process, a plot that spanned multiple currencies and countries from 2006 to 2010. One Royal Bank of Scotland trader mused in a 2007 message how the process was becoming a “cartel,” adding “its just amazing how libor fixing can make you that much money.”

The wrongdoing spread broadly, authorities say, noting that Royal Bank of Scotland “aided and abetted” UBS and other firms. A senior official at the Justice Department’s antitrust unit, Scott D. Hammond, contends that the bank “secretly rigged” interest rates.

A UBS trader, the department said, once asked a co-worker to “have a word with” another bank about Libor submissions. The UBS trader, Thomas Hayes, who was recently charged by the Justice Department with fraud, indicated that he had already approached R.B.S. for help.

The government complaints also portray a permissive culture that allowed rate-rigging to persist for four years. David Meister, the enforcement director of the trading commission, declared that “the environment was ripe for manipulation at R.B.S.”

The bank’s own records captured the scheme in striking detail, revealing how traders pressured other employees to submit certain rates. Submitters and traders sat in earshot of each other in London, forming what authorities termed a “cozy ring.” The bank eventually separated the employees, who then moved to make additional requests via instant messages.

To persuade employees who submitted Libor rates, some traders promised affection. Others offered steak and sushi. One trader resorted to begging, invoking a plea of “pretty please.” Another trader, after pressuring a colleague to submit a certain rate, offered a reward of sorts: “I would come over there and make love to you.”

When authorities began scrutinizing the bank, the traders adopted a more covert approach. In 2010, a Libor submitter rebuffed an instant message request to influence rates. But then the submitter called the trader to explain “we’re not allowed to have those conversations” over instant message.

The employees laughed, according to a transcript of the call, and the submitter reassured the trader that he would fulfill the request: “Leave it with me, and uh, it won’t be a problem.”

Well: Getting Into Your Exercise Groove

Phys Ed

Gretchen Reynolds on the science of fitness.

This isn’t meant as an insult, but you are physiologically lazy. So am I. So are we all. Using treadmill testing, scientists have definitively established that, like other animals, humans naturally aim to use as little energy as possible during most movement. So when we walk or run, our bodies tend to choose a particular cadence, a combination of step length and step frequency, that allows us to move at any given speed with as little physiological effort as possible.

How we pick that cadence, though, and whether we can or would even want to change it has been unclear. But a series of recent studies involving runners, walkers, metronomes and virtual reality curtains suggests that while the tug of physiological laziness is strong, it can be controlled, or at least tweaked, with some conscious effort — and perhaps your iPhone playlist.

In the first and most revelatory of the studies, physiologists at Simon Fraser University in British Columbia asked adult volunteers to walk on a treadmill at an easy pace. Using motion capture technology, the scientists determined how many steps each person was taking per minute at this speed. A person’s pace depends, of course, on both step length and step frequency. But because the two are inextricably entwined — lengthen your stride and you’ll take fewer steps over a given distance — studying one provides sufficient information about the other, and frequency is easier to enumerate.

After establishing each volunteer’s preferred step frequency, the scientists then sped up or slowed the treadmill, and the researchers measured how quickly people’s legs responded.

The body, remember, wants things to be easy. When you increase or decrease the speed of your walking or running, various physiological changes occur; the amount of oxygen in your blood rises or falls, for instance, because your muscles start requiring more or less of the stuff. Other biochemical changes also occur within muscle cells. Sensing those changes, the body realizes that, at this new speed, your cadence isn’t ideal; you’re taking too few or too many steps to use the least possible amount of energy. Your body adjusts.

But that process takes a little while, at least five seconds or so for the oxygen levels to change and your body to recognize the alteration, says Max Donelan, a professor at Simon Fraser University who was a co-author of the study with his graduate student Mark Snaterse and others.

However, the walkers in the study were adjusting their step frequency within less than two seconds after the treadmill speed changed, Dr. Donelan points out. They then fine-tuned their pacing after that. But the first adjustment came almost instantly.

The same process occurred when the researchers repeated the experiment with runners. If the treadmill speed changed, the runners’ step frequency shifted almost immediately, too fast for internal physiology to have played much of a role.

These insty adjustments suggest that our brains very likely contain huge libraries of preset paces, Dr. Donelan and his colleagues have concluded, of idealized, “physiologically efficient” step cadences for any given speed and condition. It seems probable, in fact, that over our lifetimes, Dr. Donelan says, our brains develop and store countless templates for most pacing situations. We learn and remember what cadence allows us to use the least energy at that speed, and when we reach that speed, we immediately default to our body’s most efficient pace.

Just how the brain recognizes that we are moving at any particular speed is not completely understood, Dr. Donelan says, but almost surely involves messages from the eyes, feet, ears, nervous system, skin and other bodily systems.

Interestingly, it seems to be quite difficult to fool your brain. When Dr. Donelan and his colleagues draped shower-curtain-like enclosures around the front of a treadmill, projected a virtual reality scene of a hallway onto it and then manipulated people’s sense of the speed with which they were moving through the hallway, they found that people’s step frequency would quickly change to match this supposed new speed. But then they would settle back into their former cadence, even as the virtual hallway continued to move past them at unnatural speed.

Visual cues simply were not strong enough to affect pacing for long.

But the scientists have found one signal that does seem effectively to override the body’s strong pull toward its preferred ways of moving: a strongly rhythmic beat. When Dr. Donelan and his colleagues fitted runners or walkers with headphones tuned to a metronome, they found that they could increase or decrease volunteers’ step frequency, even if that frequency was faster or slower than a person’s preferred step pattern. They would also maintain that pace for as long as the metronomic rhythm continued unaltered. The volunteers aligned their movement to the beat.

In practical terms, this finding suggests that music may be one of the best ways to affect the pace of your running or walking, especially if you are trying to maintain a pace with which you are not familiar or which feels awkward. Want to start jogging faster than you have in the past? Load your iPod with uptempo music, Dr. Donelan suggests (although obviously ease into any changes in training slowly, to lessen the risk of injuries).

Dr. Donelan and his colleagues even have recently launched an iPhone app called Cruise Control that allows people to coordinate their pacing with their playlists. Input your preferred running or walking speed and the app skims your music library (nonjudgmentally; if you like Nickelback, that’s your business) and strings together songs with the requisite beat, even subtly altering the tempo of songs, if needed.

But of course, if you’re comfortable with your pace as it is, stick with it. For me, the most stirring message of these recent experiments is that, left to its own devices, your body will almost always obligingly try to choose the least demanding pace for you, a goal with which I’m happy to fall into step.

Tsunami Fear After Quake Off Solomons

AUCKLAND, New Zealand — Residents of islands from the South Pacific to Australia were alerted to the possibility of a damaging tsunami on Wednesday after an 8.0-magnitude earthquake off the Solomon Islands, according to scientists and news reports from the area, but the warnings were called off a few hours later.

Edmal Palmer, the chief reporter of the Solomon Star newspaper in Honiara, the capital of the Solomon Islands, said in a telephone interview that reports from Lata, the capital of the Temotu province, were sketchy but indicated that the wave apparently had struck three villages.

“We have heard that a wave 103 centimeters high” — nearly three and a half feet — “has hit Lata, swamping the town, and five people are still missing at the moment,” Mr. Palmer said.

Lata, where the quake struck, is in Temotu Province, where the population is around 30,000. It is a three-hour flight from the Solomons’ capital, Honiara, which was not damaged by the earthquake or tsunami.

Mr. Palmer said Honiara residents were not concerned by the tsunami: “Most of us are getting ready for tonight’s UB40 concert.”

“Sea level readings indicate a tsunami was generated,” the Pacific Tsunami Warning Center said on its Web site. The earthquake struck around 11 a.m. local time in the Santa Cruz Islands, part of the Solomon chain. There were conflicting reports as to the depth of the quake.

The center said the tsunami warning was limited to the Solomon Islands, Vanuatu, Nauru, Papua New Guinea, Tuvalu, New Caledonia, Kosrae, Fiji, Kiribati, Wallis and Futuna.

A lesser alert, a tsunami watch, was declared for American Samoa, Australia, Guam, the Northern Marianas, New Zealand and eastern Indonesia.

The earthquake was not only powerful but also “shallow,” giving it significant potential to do damage, said Barry Hirshorn, a geophysicist with the National Weather Service in Hawaii. Moreover, it was a thrust earthquake, he said, meaning that the sea floor moved up or down, not sideways, contributing to the potential for a dangerous tsunami.

But after the earthquake, as scientists watched to see how far a tsunami might spread, there were few early indications of a major threat beyond the immediate area, Mr. Hirshorn said. A water rise of about three feet had been observed close to the quake, he said, still high enough to be potentially damaging but probably not big enough to threaten distant shores.

In New Zealand, thousands of people were at the beach, swimming in the sea on a glorious summer afternoon on Waitangi Day, a national holiday — quite oblivious to the potential for a tsunami. Tsunami sirens were set off late in the afternoon there, and people in coastal areas were being told to stay off beaches and out of the sea, rivers and estuaries.

The New Zealand Herald reported Wednesday afternoon on its Web site that tsunami sirens in Suva, the capital of Fiji, had been warning people to stay inside or go to higher ground.

The Sydney Morning Herald reported on its Web site Wednesday that the Solomon Islands’ National Disaster Management Office had advised those living in low-lying areas, especially on Makira and Malaita, to move to higher ground.
