James scores 32 more, Heat top Lakers 107-97

MIAMI (AP) — LeBron James ran a few steps behind the play, knowing exactly what was coming. The lob from Norris Cole arrived, and the NBA's reigning MVP rose for a catch and dunk.

He made it look easy.

He's making everything look easy right now.

James scored 32 points on 12-for-18 shooting in a record-setting show, Dwyane Wade scored 30 and the Miami Heat beat the Los Angeles Lakers 107-97 on Sunday for their fifth straight win.

It was James' fifth straight game with at least 30 points, a franchise record. He also joined Adrian Dantley (1979) and Moses Malone (1982) as the only NBA players to score at least 30 and shoot at least 60 percent in five straight outings, the team said.

"Don't take it for granted," Heat coach Erik Spoelstra said. "He's making greatness look easy."

Mario Chalmers scored 13 and Chris Bosh finished with 12 points and 11 rebounds for the Heat.

Kobe Bryant had 28 points and nine assists for the Lakers, who also got 18 points from Earl Clark. The Lakers had eight turnovers in the fourth quarter, while Miami had none.

"Turnovers," lamented Lakers coach Mike D'Antoni. "You have to give them credit. They're good."

With the win, Miami moved 2½ games clear of the New York Knicks in the Eastern Conference standings. The Knicks lost to the Los Angeles Clippers earlier Sunday.

Dwight Howard and Steve Nash each scored 15 for the Lakers.

"They have a couple of sensational players over there that made some big plays," Bryant said.

Indeed, James and Wade stole the show down the stretch.

Wade also shot 12 for 18 for Miami, which shot 55 percent as a team and held a 38-29 edge in rebounding. James scored 20 in the second half and Wade had 18 in the final two quarters, but the defending NBA champions weren't able to pull away until the final minutes.

Wade had five straight points for Miami, the last of them coming with 7:15 left when his three-point play put the Heat up 89-82 — at that point, their biggest lead of the day.

A minute later, Wade started what might have been Miami's signature sequence of the game.

He stepped in front of a pass by Bryant under the basket, then flipped it to Bosh before falling out of bounds. Bosh got the ball to Cole, who beat Nash down the court, then lobbed a pass over his head to James, who soared for a slam that gave the Heat a seven-point lead once again.

"You could feel the buzz in the arena today," James said. "We were just happy that we were able to play our game, weather some of their storms that they had and come out with a win."

With 3:25 left, James turned in another highlight.

He stole a pass, drove down the court and Nash — who found himself in the lane against a fast-charging James plenty of times Sunday, all to no avail — simply had no chance.

It was almost as if Nash wasn't even in James' field of vision. He leaped for a dunk, giving him 30 points and the franchise record, and Miami's lead was nine. Bryant scored on the next Lakers possession, but Shane Battier hit a 3-pointer with 2:42 left to put Miami up 100-90 for the first double-digit lead for either team all day.

That was the last gasp for the Lakers, who finished their road trip at 4-3.

"We had our chances, but we weren't good enough tonight," Nash said. "We had too many breakdowns and we had opportunities to stretch the lead at times in the game and we couldn't do that either so probably in the end we didn't deserve it."

The teams finished the first half tied at 53, and the third period didn't allow either team much in the way of breathing room either, until the final seconds.

That's when James started flexing some muscle.

James scored Miami's last 11 points of the third, all in the final 4:20, and four of those came in the last six seconds. He was fouled by Clark and made the first free throw. Then the second attempt was tipped back out by Battier to James, who was just beyond the 3-point line. He connected from there, and the Heat took a 78-73 lead into the fourth.

It took a few more minutes, but eventually James and Wade helped Miami put it away.

"D-Wade came and he just started cooking in the fourth quarter," Bryant said. "He started doing what D-Wade does and made sensational play after sensational play."

Rapper Lil Wayne — a semi-regular in the crowd at Heat games — was there for the first half, then tweeted that he was ejected for rooting for the Lakers. Security personnel were seen talking to the rapper at halftime, and a Heat spokesman said after the game that he chose to leave on his own and was not ejected.

NOTES: The Heat have now won six of their last seven games against the Lakers. ... James made his first five shots, which left him at 42 for his last 52 attempts from the floor to that point, a ridiculous 81-percent clip. ... Bryant had five assists in the first quarter, tying a season best. ... Celebrities in attendance included Miami Hurricanes coach Jim Larranaga, pro golfer Justin Rose and Donald Trump. ... LSU football coach Les Miles live-tweeted the game, noting that James is "more athletic in person."

For Families Struggling with Mental Illness, Carolyn Wolf Is a Guide in the Darkness

When a life starts to unravel, where do you turn for help?

Melissa Klump began to slip in the eighth grade. She couldn’t focus in class, and in a moment of despair she swallowed 60 ibuprofen tablets. She was smart, pretty and ill: depression, attention deficit disorder, obsessive-compulsive disorder, either bipolar disorder or borderline personality disorder.

In her 20s, after a more serious suicide attempt, her parents sent her to a residential psychiatric treatment center, and from there to another. It was the treatment of last resort. When she was discharged from the second center last August after slapping another resident, her mother, Elisa Klump, was beside herself.

“I was banging my head against the wall,” the mother said. “What do I do next?” She frantically called support groups, therapy programs, suicide prevention lines, anybody, running down a list of names in a directory of mental health resources. “Finally,” she said, “somebody told me, ‘The person you need to talk to is Carolyn Wolf.’ ”

That call, she said, changed her life and her daughter’s. “Carolyn has given me hope,” she said. “I didn’t know there were people like her out there.”

Carolyn Reinach Wolf is not a psychiatrist or a mental health professional, but a lawyer who has carved out what she says is a unique niche, working with families like the Klumps.

One in 17 American adults suffers from a severe mental illness, and the systems into which they are plunged — hospitals, insurance companies, courts, social services — can be fragmented and overwhelming for families to manage. The recent shootings in Newtown, Conn., and Aurora, Colo., have brought attention to the need for intervention to prevent such extreme acts of violence, which are rare. But for the great majority of families watching their loved ones suffer, and often suffering themselves, the struggle can be boundless, with little guidance along the way.

“If you Google ‘mental health lawyer,’ ” said Ms. Wolf, a partner with Abrams & Fensterman, “I’m kinda the only game in town.”

On a recent afternoon, she described in her Midtown office the range of her practice.

“We have been known to pull people out of crack dens,” she said. “I have chased people around hotels all over the city with the N.Y.P.D. and my team to get them to a hospital. I had a case years ago where the person was on his way back from Europe, and the family was very concerned that he was symptomatic. I had security people meet him at J.F.K.”

Many lawyers work with mentally ill people or their families, but Ron Honberg, the national director of policy and legal affairs for the National Alliance on Mental Illness, said he did not know of another lawyer who did what Ms. Wolf does: providing families with a team of psychiatrists, social workers, case managers, life coaches, security guards and others, and then coordinating their services. It can be a lifeline — for people who can afford it, Mr. Honberg said. “Otherwise, families have to do this on their own,” he said. “It’s a 24-hour, 7-day-a-week job, and for some families it never ends.”

Many of Ms. Wolf’s clients declined to be interviewed for this article, but the few who spoke offered an unusual window on the arcane twists and turns of the mental health care system, even for families with money. Their stories illustrate how fraught and sometimes blind such a journey can be.

One rainy morning last month, Lance Sheena, 29, sat with his mother in the spacious family room of her Long Island home. Mr. Sheena was puffy-eyed and sporadically inattentive; the previous night, at the group home where he has been living since late last summer, another resident had been screaming incoherently and was taken away by the police. His mother, Susan Sheena, eased delicately into the family story.

“I don’t talk to a lot of people because they don’t get it,” Ms. Sheena said. “They mean well, but they don’t get it unless they’ve been through a similar experience. And anytime something comes up, like the shooting in Newtown, right away it goes to the mentally ill. And you think, maybe we shouldn’t be so public about this, because people are going to be afraid of us and Lance. It’s a big concern.”

Her son cut her off. “Are you comparing me to the guy that shot those people?”

“No, I’m saying that anytime there’s a shooting, like in Aurora, that’s when these things come out in the news.”

“Did you really just compare me to that guy?”

“No, I didn’t compare you.”

“Then what did you say?”

Samsung Challenges Apple’s Cool Factor

Apple, for the first time in years, is hearing footsteps.

The maker of iPhones, iPads and iPods has never faced a challenger able to make a truly popular and profitable smartphone or tablet — not Dell, not Hewlett-Packard, not Nokia, not BlackBerry — until Samsung Electronics.

The Korean manufacturer’s Galaxy S III smartphone is the first device to run neck and neck with Apple’s iPhone in sales. Armed with other Galaxy phones and tablets, Samsung has emerged as a potent challenger to Apple, the top consumer electronics maker. The two companies are the only ones turning profits in the highly competitive mobile phone industry, with Apple taking 72 percent of the earnings and Samsung the rest.

Yet these two rivals, who have battled in the marketplace and in the courts worldwide, could not be more different. Samsung Electronics, a major part of South Korea’s expansive Samsung Group, makes computer chips and flat-panel displays as well as a wide range of consumer products including refrigerators, washers and dryers, cameras, vacuum cleaners, PCs, printers and TVs.

Where Apple stakes its success on creating new markets and dominating them, as it did with the iPhone and iPad, Samsung invests heavily in studying existing markets and innovating inside them.

“We get most of our ideas from the market,” said Kim Hyun-suk, an executive vice president at Samsung, in a conversation about the future of mobile devices and television. “The market is a driver, so we don’t intend to drive the market in a certain direction,” he said.

That’s in stark contrast to the philosophy of Apple’s founder Steven P. Jobs, who rejected the notion of relying on market research. He memorably said that consumers don’t know what they want.

Nearly everything at Samsung, from the way it does research to its manufacturing, is unlike Apple. It taunts Apple in its cheeky advertisements while Apple stays above the fray.

And the Korean manufacturer may even be putting some pressure on Apple’s world-class designers. Before Apple released the iPhone 5, which had a larger screen than earlier models, Samsung had already been selling phones with even bigger displays, like the 5.3-inch screen Galaxy Note, a smartphone so wide that gadget blogs call it a phablet.

Samsung outspends Apple on research and development: $10.5 billion, or 5.7 percent of revenue, compared with $3.4 billion, or 2 percent. (Samsung Electronics is slightly bigger than Apple in terms of revenue — $183.5 billion compared with $156.5 billion — but Apple is larger in terms of stock market value.)

Samsung has 60,000 staff members working in 34 research centers across the globe, including, Russia, Britain, India, Japan, Israel, China and Silicon Valley. It polls consumers and buys third-party research reports, but it also embeds employees in countries to study trends or merely to find inspiration for ideas.

Designers of the Galaxy S III say they drew inspiration from trips to Cambodia and Helsinki, a Salvador Dalí art exhibit and even a balloon ride in an African forest. (It employs 1,000 designers with different backgrounds like psychology, sociology, economy management and engineering.)

“The research process is unimaginable,” said Donghoon Chang, an executive vice president of Samsung who leads the company’s design efforts. “We go through all avenues to make sure we read the trends correctly.” He said that when the company researches markets for any particular product, it is also looking at trends in fashion, automobiles and interior design.

Hangil Song, a Samsung product designer, described a visit to the Marina Bay Sands resort in Singapore, where he said he was amazed by the views of the sky, the cityscape and the water. He wanted to create an effect where water was overflowing from the screen. As a result, taps and swipes on the Galaxy S III’s phone screen create a unique ripple effect.

The genesis of the wide Galaxy Note phone reflects that same kind of consumer research. From focus groups and surveys, Samsung found that many respondents wanted a device that was good for handwriting, drawing and sharing notes. Asian-language speakers, in particular, found it easier to write characters on a device using a pen than typing. Those insights led to the Note, a smartphone that comes with a digital pen.

In courts, jury members have said some of Samsung’s research appears to comes closer to copying. Apple sued Samsung in Federal District Court last year for patent infringement and won a $1 billion judgment. One of the most explosive pieces of evidence was a detailed report breaking down each hardware and software feature of the iPhone and how each compared to Samsung phone features. Samsung is fighting the decision in court.

Israeli Says Syria Twisted Comments by Rebel Supporter

BEIRUT, Lebanon — A public relations controversy erupted Saturday after a leading Israeli newspaper published comments from a brief interview with the leader of Syria’s main exile opposition group.

The news media outlets of the Syrian government, and its ally Hezbollah, the Lebanese militant group, reported that the opposition leader had declared that Israel had “nothing to fear” from a rebel-led Syrian government. Moreover, the reports said, the opposition was working with other countries to keep Syria’s chemical weapons away from Hezbollah, which he called a “son of the devil.”

But the opposition leader, Sheik Ahmad Moaz al-Khatib, never said any of that, according to the article in the Israeli newspaper, Yediot Aharonot, and its author, a prominent Israeli defense expert, Ronen Bergman.

Sheik Khatib was quoted in the article reiterating the opposition’s promise to keep Syria’s chemical arsenal out of “the hands of unauthorized elements,” and it was the international community, he said, not Israel, that had “nothing to fear.”

When Sheik Khatib realized that Mr. Bergman was an Israeli — after glancing at his business card — he abruptly ended the conversation, Mr. Bergman said in a Skype interview, repeating what he had written.

The original article was published only in Hebrew — and only in print — so it was the Arabic and English versions put out by the Syrian government and Hezbollah that raced around the Internet on Saturday, provoking outrage from government supporters and opponents at Sheik Khatib, who posted a message on his Facebook page denying that he had given the interview.

Yet the episode appeared to have been more than a simple misunderstanding. Syria’s conflict is not only a shooting war but also a propaganda war. Pro-government media apparently could not resist the chance to bolster their contention that the rebellion had been promoted by Israel and the West to punish Syria and its president, President Bashar al-Assad, for taking uncompromising positions against Israel.

“Unfortunately, the original text was less exciting,” Mr. Bergman said. “I would be happy if he would say something like, ‘Yes, we will make peace with Israel’ — then I would get the front page.” As it was, the article elicited little reaction in Israel.

But misrepresentation of the article suggested that it hit a nerve on one issue. An unnamed opposition member, not Sheik Khatib, called Hezbollah “sons of the devil,” according to Mr. Bergman, and said the rebel coalition was working with other countries to ensure that “not one piece of military equipment, not chemical weapons and not any other item, will pass into their hands.”

Syria is Hezbollah’s main conduit for arms, and Hezbollah has backed Mr. Assad’s bloody crackdown at great cost to its popularity in the wider Arab world.

Although Mr. Bergman said the opposition member was offering his own opinion and not presenting official policy, his comments bolstered the widely held view that a rebel-led government might halt the shipment of Iranian arms through Syria to Hezbollah. Hezbollah, a Shiite group and political party, is also concerned about the rise within the rebel movement of extremist Sunni jihadists who view Shiites as apostates.

The misleading reports appeared to be an attempt to further divide the opposition. Sheik Khatib found himself fending off critics from within the anti-Assad movement who objected to his even speaking with an Israeli reporter, though by all accounts he did not initially realize that Mr. Bergman was an Israeli.

It was the second time in a month that Sheik Khatib found himself on the defensive. He recently proposed talks with members of Mr. Assad’s government, but had not built political support for the proposal.

On Friday, Syria’s information minister, Omran al-Zoubi, gave the first official response to the proposal, saying that the government would negotiate with any opposition members who agreed to lay down their arms.

On Saturday, Mr. Assad named new cabinet ministers for oil, finance, social affairs, labor, housing, public works and agriculture, as Syria faces growing economic problems and shortages of electricity, fuel and bread.

Wisconsin beats No. 3 Michigan 65-62 in OT

MADISON, Wis. (AP) — When Ben Brust tied the game at the end of regulation with a shot just from just inside midcourt, his teammate Mike Bruesewitz looked over at Wisconsin coach Bo Ryan and saw something unusual.

His coach had both his arms in the air.

"You know when he shows some emotion, you've done something pretty special," Bruesewitz said.

Brust hit a tie-breaking 3-pointer with less than 40 seconds left in overtime as Wisconsin beat No. 3 Michigan 65-62 on Saturday.

"It was awesome, something I'll remember forever, and I'm sure a lot of people will," Brust said of the game, which ended with students storming the court and Bruesewitz taking the public address announcer's microphone to thank the crowd as students celebrated around him.

The Wolverines became the third top three team to lose this week as No. 1 Indiana lost to Illinois and No. 2 Florida was beaten by Arkansas. This should be the sixth straight week with a different No. 1 in The Associated Press' Top 25.

Brust's shot at the end of regulation was a dramatic turn of events for Wisconsin (17-7, 8-3 Big Ten) and a soul crusher for Michigan (21-3, 8-3).

Just moments earlier, Tim Hardaway Jr. hit a contested 3-pointer to put the Wolverines up 65-62 with less than 3 seconds left in regulation.

Following a timeout, Bruesewitz passed up his first option in the inbounds play and hit Brust in stride. The guard took one dribble across halfcourt and launched the shot, which hit nothing but net.

Ryan said the play was drawn up to see how Michigan defended the first cutter, Brust read the defense and reacted.

"The best thing was Mike's pass on the dime on the run, didn't have to reach back for it, able to catch it all in one motion," Ryan said.

Michigan still had fouls to give before the shot, and coach John Beilein said the order coming out of the timeout was to foul. He also put Caris LeVert on Brust to bolster the defense.

"We were definitely fouling, wanted to keep everyone in front of us and (Brust) turned the corner on (LeVert) just enough that he couldn't foul him," Beilein said. "I thought we had them once they couldn't get their initial guy.

"With Caris' quickness, we thought he could get there, but he didn't."

For all the fireworks in the final 3 seconds, the teams only managed seven points in overtime, including Brust's winning 3-pointer.

Following Brust's shot, Hardaway couldn't connect on his drive to the hoop on the next Michigan possession, and Glenn Robinson III fouled Jared Berggren on the rebound.

The Wolverines went to a full-court press with two more fouls to give. But the Badgers broke the press, and Michigan had to foul twice more to finally put Ryan Evans on the free throw line.

Evans, who shoots less than 43 percent from the line, missed the front end of a 1-and-1, and Burke couldn't connect in a rushed final possession for the Wolverines.

It was another grinding win for the Badgers keyed by their defense. Michigan came in as one of the top scoring teams in the country at almost 78 points per game. But Wisconsin held Michigan to less than 40 percent shooting from the field, including 5 of 18 from beyond the 3-point line.

Michigan was 1 for 7 from the field in overtime, and the offensive futility was highlighted by one sequence in which Mitch McGary stole the ball outside the 3-point line and drove the other way only to miss the layup with Berggren defending the rim.

Beilein said the Wolverines missed out on 14 points thanks to missed layups.

"I'm not talking about when they're really contesting," Beilein said. "I'm talking about we had the ball, the basket and us, and it didn't go in."

Brust scored 14 points for the Badgers, while Berggren added 13 and eight rebounds. Sam Dekker scored 12 points, while Evans finished with 11 points and nine rebounds.

Burke scored 19 points to lead Michigan, but needed 21 shots to do it. Hardaway added 18, and McGary had 12 points and eight rebounds.

It was the second straight game for both teams to go past regulation after the Badgers beat Iowa 74-70 in double overtime on Wednesday and Michigan downed Ohio State 76-74 in overtime on Tuesday.

Several Wisconsin players said consecutive overtime games exemplified their will to win even as critics contend they're not talented enough, not fast enough and, as Bruesewitz said he's seen on Twitter, not good-looking enough.

"We have a group of guys in that locker room that believe and is going to fight until the end until you tell us we can't play any more basketball," Berggren said. "We just find a way to get it done."

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.

U.S. Use of Mexican Battery Recyclers Is Faulted

United States companies are sending spent lead batteries to recycling plants in Mexico that do not meet American environmental standards, according to an environmental agency created under the North American Free Trade Agreement, putting Mexican communities at risk.

In a blistering report submitted this week, the agency, the Commission for Environmental Cooperation, notes that the United States does not fully follow procedures common among developed nations that treat international battery shipments as hazardous waste. It faults environmental agencies on both sides of the border for lapses in regulation and enforcement. Cross-border trade in lead batteries increased by up to 525 percent from 2004 to 2011, the report said.

The report, which has been circulating in draft form, has been forwarded to the governments of the United States, Canada and Mexico, which have 60 days to object to its publication. An estimated 20 percent of lead acid batteries from the United States now go to Mexico for recycling, according to trade statistics.

“There needs to be better coordination between government agencies and better cross-border tracking,” said Evan Lloyd, who was the agency’s executive director until late last year and oversaw the yearlong study.

The report highlighted a number of shortcomings: Customs data on the number of batteries crossing the border did not mesh with counts by the United States Environmental Protection Agency. Though the E.P.A. requires notice of batteries leaving the United States, there was no effort to make sure that they had arrived at qualified recyclers in Mexico. The data that battery companies sent to the E.P.A. about exports consisted of “piles of paper,” Mr. Lloyd said, and it was never amassed into an electronic database that would be “useful to regulators.”

Almost all lead acid batteries used in the United States are recycled to extract the lead for reuse because lead is a dangerous pollutant and because it is a valuable commodity. Lead batteries are used in vehicles, cellphone towers and wind turbines.

Since 2008, new United States limits on lead pollution have made domestic recycling complicated and costly. That has helped propel the recycling trade to Mexico, both legally and illegally, environmental groups say, because that country has less stringent limits for lead pollution, and far less vigorous enforcement.

“There’s a pretty consistent pattern suggesting that exports are the direct result of U.S. emissions standards,” said Perry Gottesfeld, executive director of Occupational Knowledge International, which has led the campaign against lead poisoning internationally. Mr. Gottesfeld noted that a Mexican plant owned by a major American recycler, Johnson Controls International, puts out more than 30 times as much lead emissions as its newest plant in the United States.

“What Mexico needs to do is to get its recycling up to U.S. standards, and the U.S. needs to do a much better job of tracking batteries overseas,” he said. In an e-mail, Johnson Controls, based in Milwaukee, said it was “modernizing and reinvesting” in the Mexican facility, acquired in 2005, “to reduce its environmental footprint.”

The report was initiated in response to a report by Occupational Knowledge International and Fronteras Comunes, a Mexican environmental group, as well as to an investigative article in The New York Times, Mr. Lloyd said. Soil collected by The Times in a school playground near a recycling plant outside Mexico City were found to have lead levels five times those allowed in the United States.

Lead poisoning causes high blood pressure, kidney damage and abdominal pain in adults, and serious developmental delays and behavioral problems in young children. When batteries are broken for recycling, the lead is released as dust and, during melting, as lead-laced emissions.

In the United States, recyclers operate in highly mechanized, tightly sealed plants, with smokestack scrubbers and extensive monitors to detect lead release. Plants in Mexico vary greatly in safety standards, and in some, the recycling process is little more than men with hammers smashing batteries and melting down their contents in furnaces.

In recent months, there have been new efforts to curb the flow of batteries south of the border, though many battery makers have fought that. In response to a draft of the report released late last year, Battery Council International, an industry group, said it opposed “the creation of additional burdensome certification programs.”

Last year, the United States General Services Administration, which is responsible for federal vehicles, asked ASTM International, an independent standards agency, to explore a voluntary standard for battery recycling.

But that effort came to naught after the proposal was voted down at an open meeting attended by representatives from industry, government and environmental groups in December. Of the 103 people at the meeting, 49 worked for Johnson Controls.

Super Bowl blackout was caused by electrical relay

NEW ORLEANS (AP) — The company that supplied electricity to the Super Bowl says the blackout that halted the big game was caused by a device it installed specially to prevent a power failure.

But the utility stopped short of taking all the blame and said Friday that it was looking into whether the electrical relay at fault had a design flaw or a manufacturing defect.

The relay had been installed as part of a project begun in 2011 to upgrade the electrical system serving the Superdome in anticipation of the championship game. The equipment was supposed to guard against problems in the cable that links the power grid with lines that go into the stadium.

"The purpose of it was to provide a newer, more advanced type of protection for the Superdome," Dennis Dawsey, an executive with Entergy Corp., told members of the City Council. Entergy is the parent company of Entergy New Orleans, the city's main electric utility.

Entergy officials said the relay functioned with no problems during January's Sugar Bowl and other earlier events. It has been removed and will be replaced.

All systems at the Superdome are now working, and the stadium was to host a major Mardi Gras event Saturday night, said Doug Thornton, an executive with SMG, the company that manages the stadium for the state.

The relay was installed in a building near the stadium known as "the vault," which receives a line directly from a nearby Entergy substation. Once the line reaches the vault, it splits into two cables that go into the Superdome.

Sunday's power failure cut lights to about half of the stadium, halting play between the Baltimore Ravens and San Francisco 49ers and interrupting the nation's most-watched sporting event for 34 minutes.

Not long after the announcement, the manufacturer of the relay, Chicago-based S&C Electric Co., released a statement saying that the blackout occurred because system operators had put the relay's so-called trip setting too low to allow the device to handle the incoming electric load.

The equipment was owned and installed by Entergy New Orleans.

"If higher settings had been applied, the equipment would not have disconnected the power," said Michael J.S. Edmonds, vice president of strategic solutions for S&C.

In a follow-up statement, Entergy said that tests conducted by S&C and Entergy on the two relays at the Superdome showed that one worked as expected, the other did not.

Entergy spokesman Mike Burns said both relays had the same trip setting.

Entergy's announcement came shortly before company officials went before a committee of the City Council, which is the regulatory body for the company.

During the committee hearing, council member Susan Guidry asked Entergy executives whether they were "fairly certain" that the relay was faulty.

"That is correct," Dawsey said.

However, when asked if the outage was caused by the design or a defect in a part of the equipment, Entergy New Orleans CEO Charles Rice said that had not been determined.

"The equipment did not function properly," Rice said. "At this particular time, based upon our analysis, we cannot say definitively that there was a defect in design. What we do know is that the equipment for some unknown reason, at this particular time, did not react the way that it should have."

Asked if Entergy and SMG still plan to hire a third-party investigator to get to the bottom of the cause, Rice said that possibility remains open.

"We'll work closely with SMG, and if there is a need for a third-party investigation, we will do that," Rice said, adding that Entergy was also working with the relay manufacturer.

Shabab Mehraeen, an assistant professor of electrical engineering at Louisiana State University, said relays are common electrical fixtures in businesses and massive facilities such as the Superdome.

"They are designed to keep a problem they sense from becoming something bigger, like a fire or catastrophic event," he said.

The devices vary in size. Mehraeen, who was not familiar with the relay at the Superdome, said he "wouldn't be surprised if it was bigger than a truck."

The reasons the devices fail are the subject of much academic research into the interaction of relays with the complex electrical systems they regulate.

"It's not unusual for them to have problems," Mehraeen said. "They can be unpredictable, despite national testing standards recommended by manufacturers."

Entergy and SMG had both upgraded lines and equipment in the months leading up to the Super Bowl. Rice said the new gear, with the faulty relay, was installed as part of a $4.2 million upgrade by Entergy that included a new power line dedicated solely to the stadium.

In a separate project, SMG replaced lines coming into the stadium after managers expressed concerns the Superdome might be vulnerable to a power failure like the one that struck Candlestick Park during an NFL game in 2011.

Thornton stressed Friday that the dome was drawing only about two-thirds of its power capacity Super Bowl night. He said typical NFL games in late August or September can draw a little more.

Friday's announcement appeared to absolve Superdome officials of any missteps in the blackout.

City officials had worried that the Super Bowl outage might harm New Orleans' chances of getting another NFL championship game.

But NFL Commissioner Roger Goodell downplayed that possibility, saying the league planned to keep New Orleans in its Super Bowl plans. Mayor Mitch Landrieu said the city intends to bid for the game again in 2018.

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 brown 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.
