French Family of 7 Kidnapped in Cameroon

PARIS (AP) — A French family of seven — including four children — was kidnapped on Tuesday in northern Cameroon, and officials suggested that the Islamic extremist sect Boko Haram was behind it.

Details of the kidnapping were not immediately clear. However, President Francois Hollande, speaking during a visit to Greece, noted that France is engaged in a military campaign in Mali to rout out jihadists who had taken control of the north. Terrorists, he said, "are not just in Mali."

Hollande warned French citizens in the region to avoid putting themselves in dangerous situations.

A total of 15 French citizens are currently being held in western Africa — one other in Nigeria and seven thought to be in northern Mali.

A French official close to the embassy in Cameroon said the family was believed to have been taken from northern Cameroon to Nigeria, where on Monday a little-known extremist group called Ansaru claimed responsibility for a separate abduction of seven foreigners.

Boko Haram — which means "Western education is sacrilege" — has launched a guerrilla campaign of bombings and shootings across Nigeria's predominantly Muslim north. It is blamed for at least 792 killings last year alone, according to an AP count. It is known to have ties to al-Qaida in the Islamic Maghreb, or AQIM, an Algerian-based group that opened a front in Mali.

"If everything is confirmed, this signifies that the fight against terrorist groups is a necessity," Foreign Minister Laurent Fabius said in Paris. "There is a battle to be led by the international community against terrorist groups and narco-terrorists," a reference to the trafficking in drugs, cigarettes and other commodities that has flourished in northern Mali under the extremists.

The latest kidnappings have added to fears of instability and danger toward Westerners. Before Tuesday, there were eight French citizens being held in the region, including one who was taken in Nigeria.

An analysis published Monday by Stratfor, a U.S.-based private global intelligence firm, warned that there likely will be more attacks by Ansaru targeting Westerners and Western interests in Nigeria, as well as neighboring nations.

Pistorius: Thought lover an intruder in shooting

PRETORIA, South Africa (AP) — Oscar Pistorius wept Tuesday as his defense lawyer read the athlete's account of how he shot his girlfriend to death on Valentine's Day, claiming he had mistaken her for an intruder.

Prosecutors, however, told a packed courtroom that the double-amputee known as the Blade Runner intentionally and mercilessly shot and killed 29-year-old Reeva Steenkamp model as she cowered inside a locked bathroom.

Pistorius told the Pretoria Magistrate's Court at a bail hearing he felt vulnerable in the presence of an intruder inside the bathroom because he did not have on his prosthetic legs on, and fired into the bathroom door.

In a major point of contention that has already emerged, prosecutor Gerrie Nel said Pistorius took the time to put on his prostheses, walked seven meters (yards) from the bed to the enclosed toilet inside his bathroom and only then opened fire. Three of the bullets hit Steenkamp of the four that were fired into the door, Nel said.

Pistorius said in his sworn statement that after o0pening fire, he realized that Steenkamp was not in his bed.

"It filled me with horror and fear," Pistorius said. The 26-year-old Olympian said he put on his prosthetic legs and tried to kick down the door before finally giving up and bashing it in with a cricket bat. Inside, he said he found Steenkamp, slumped over. He said he lifted her bloodied body into his arms and tried to carry her downstairs to seek medical help.

But by then, it was too late.

"She died in my arms," the athlete said.

The Valentine's Day shooting death hocked South Africans and many around the world who idolized Pistorius for overcoming adversity to become a sports champion, competing in the London Olympics last year in track besides being a Paralympian. Steenkamp was a model and law graduate who made her debut on a South African reality TV program that was broadcast on Saturday, two days after her death.

Nel charged Pistorius with premeditated murder and said the athlete opened fire after they engaged in a shouting match.

"She couldn't go anywhere. You can run nowhere," Nel said. "It must have been horrific."

A conviction of premeditated murder carries a mandatory sentence of life in jail.

Chief Magistrate Desmond Nair ruled that Pistorius must face the harshest bail requirements available in South African law. That means Pistorius' lawyers must offer "exceptional" reasons for the athlete to be free before trial, besides simply giving up his two South African passports and posting a cash bond.

Pistorius sobbed softly as his lawyer, Barry Roux, insisted the shooting was an accident and that there was no evidence to substantiate a murder charge.

"Was it to kill her, or was it to get her out?" he asked about the broken-down door. "We submit it is not even murder. There is no concession this is a murder."

Pistorius' emotional outbursts again played a part in how the hearing progessed, as it did during an initial hearing Friday. At one point, Nair stopped the hearing after Pistorius wept as Roux read a portion of the athlete's statement describing how Steenkamp bought him a Valentine's Day present, but wouldn't let him open it the night before.

"Maintain your composure," the magistrate said. "You need to apply your mind here."

Pistorius' voice quivered when he answered: "Yes, my lordship."

Affidavits from friends of Pistorius and Steenkamp read out by Roux in the hearing described the two as a charming, happy couple. The night before the killing, they said, Pistorius and Steenkamp had canceled separate plans in order to spend the night before Valentine's Day together at his home, in a gated neighborhood of Pretoria.

Outside the court, several dozen singing women protested against domestic violence and waved placards urging that Pistorius be refused bail. "Pistorius must rot in jail," one placard said.

As details emerged at the dramatic court hearing in the capital, Steenkamp's body was being cremated Tuesday at a memorial service in the south-coast port city of Port Elizabeth. The family said members had arrived from around the world. Six pallbearers carried her coffin, draped with a white cloth and covered in white flowers, into the church for the private service.

South Africa has some of the world's worst rates of violence against females and the highest rate in the world of women killed by an intimate partner, according to a study by the Medical Research Council. Another council study estimates a child or woman is raped every four minutes. While homicide rates have dropped, the number of women killed by current or former partners has increased, said the council's Professor Rachel Jewkes. At least three women are killed by a partner every day in the country of 50 million, she said.

Steenkamp campaigned actively against domestic violence and had tweeted on Twitter that she planned to join a "Black Friday" protest by wearing black in honor of a 17-year-old girl who was gang-raped and mutilated two weeks ago.

What "she stood for, and the abuse against women, unfortunately it's gone right around and I think the Lord knows that statement is more powerful now," her uncle Mike Steenkamp, the family's spokesman, said after her memorial.

He said the family had planned a big get-together at Christmas but that had not been possible. "But we are here today as a family and the only one who's missing is Reeva," he said, breaking down and weeping.

Pistorius has lost several valuable sponsorships estimated to be worth more than $1 million a year.

On Tuesday, the athlete was ousted from a pro-gay campaign being launched in Cape Town, organizers said. In a video axed from the campaign, Pistorius says: "You don't have to worry. You don't have to change. Take a deep breath and remember, 'It will get better.'"

And Clarins Group, which owns Thierry Mugler Perfumes, said in an email that "out of respect and compassion for the families involved in this tragedy, Thierry Mugler Perfumes have taken the decision to withdraw all of their advertising campaigns featuring Oscar Pistorius."

Well: Susan Love's Illness Gives New Focus to Her Cause

During a talk last spring in San Francisco, Dr. Susan Love, the well-known breast cancer book author and patient advocate, chided the research establishment for ignoring the needs of people with cancer. “The only difference between a researcher and a patient is a diagnosis,” she told the crowd. “We’re all patients.”

It was an eerily prescient lecture. Less than two months later, Dr. Love was given a diagnosis of acute myelogenous leukemia. She had no obvious symptoms and learned of her disease only after a checkup and routine blood work.

“Little did I know I was talking about myself,” she said in an interview. “It was really out of the blue. I was feeling fine. I ran five miles the day before.”

Dr. Love, a surgeon, is best known as the author of the top-selling “Dr. Susan Love’s Breast Book” (Da Capo Press, 2010) now in its fifth edition. She is also president of the Dr. Susan Love Research Foundation, which focuses on breast cancer prevention and research into eradicating the disease. But after decades of tireless advocacy on behalf of women with breast cancer, Dr. Love found herself in an unfamiliar role with an unfamiliar disease.

“There is a sense of shock when it happens to you,” she said. “In some ways I would have been less shocked if I got breast cancer because it’s so common, but getting leukemia was a world I didn’t know. Even when you’re a physician, when you get shocking news like this you sort of forget everything you know and are scared the same as everybody else.”

Because Dr. Love’s disease was caught early, she had a little time to seek second opinions and choose her medical team. She chose City of Hope in Duarte, Calif., because of its extensive experience in bone marrow transplants. At 65, Dr. Love was startled to learn she was considered among the “elderly” patients for this type of leukemia.

She was admitted to the hospital and underwent chemotherapy. Because her blood counts did not rebound after the treatment, her stay lasted a grueling seven weeks.

She went home for just two weeks, and then returned to the hospital for a bone-marrow transplant, with marrow donated by her younger sister, Elizabeth Love De Garcia, 53, who lives in Mexico City.

Although the transplant itself was uneventful, the next four weeks were an ordeal. Dr. Love developed pain and neuropathy from the chemotherapy drugs. Dr. Love’s wife, Dr. Helen Cooksey; daughter, Katie Love-Cooksey, 24; and siblings offered round-the-clock support. Ms. Love-Cooksey slept in the hospital every night. “I wasn’t very articulate during that time, but I always had my family there,” Dr. Love said. “They were great advocates for me.”

The transplant “is quite an amazing thing,” Dr. Love said. Her blood type changed from O positive to B positive, the same type as her sister. She also has inherited her sister’s immune system, and a lifelong allergy to nickel has disappeared. “I can wear cheap jewelry now,” she said. She returned to work last month.

Dr. Love has been told her disease is in remission, though her immune system remains compromised and she is more susceptible to infection. So she avoids crowds, air travel and other potential sources of cold and flu viruses.

While Dr. Love has always been a strong advocate for women undergoing cancer treatment, she says her disease and treatment has strengthened her understanding of what women with breast cancer and other types of cancer go through during treatments.

“There are little things like having numb toes or having less stamina to building muscles back up after a month of bed rest,” she said. “There is significant collateral damage from the treatment that is underestimated by the medical profession. There’s a sense of ‘You’re lucky to be alive, so why are you complaining?’ ”

Dr. Love says her experience has emboldened her in her quest to focus on the causes of disease rather than new drugs to treat it.

“I think I’m more impatient now and in more of a hurry,” she said. “I’ve been reminded that you don’t know how long you have. There are women being diagnosed every day. We don’t have the luxury to sit around and come up with a new marketing scheme. We have to get rid of this disease, and there is no reason we can’t do it.”

People who remain skeptical about the ability to eradicate breast cancer should look to the history of cervical cancer, she said. Decades ago, a woman with an abnormal Pap smear would be advised to undergo hysterectomy. Now a vaccine exists that can protect women from the infection that causes most cervical cancers.

“We need to focus more on the cause of breast cancer,” she said. “I’m still very impressed with the fact that cancer of the cervix went from being a disease that robbed women of their fertility, if not their lives, to having a vaccine to prevent it.”

Dr. Love, who wrote a book called “Live a Little!,” said illness has also made her grateful that she didn’t put off her “bucket list” and that she has traveled the world and focused on work she finds challenging and satisfying.

“It just reminds you that none of us are going to get out of here alive, and we don’t know how much time we have,” she said. “I say this to my daughter, whether it’s changing the world or having a good time, that we should do what we want to do. I drink the expensive wine now.”

Media Decoder Blog: NBC News Hires David Axelrod as Political Analyst

NBC News announced Tuesday that it had hired David Axelrod, the chief political strategist for both of Barack Obama’s presidential elections, as a full-time political analyst for the news organization.

He will appear on news programs for NBC’s broadcast network and for its cable news channel MSNBC. That channel has positioned itself aggressively as the liberal counterpart to the conservative-leaning Fox News Channel.

Mr. Axelrod’s hiring at MSNBC emulates Fox’s hiring of Karl Rove, who filled the similar political post for George W. Bush.

The path from political adviser to expert commentator on television has been well trod. George Stephanopoulos, who advised President Clinton , joined ABC News as a journalist. He is, of course, now the anchor of “Good Morning, America” for ABC.  And MSNBC already employs Steve Schmidt, the senior strategist for the losing campaign of Senator John McCain.

Mr. Axelrod most recently was named political director at the Institute of Politics as the University of Chicago, his alma mater, and a Distinguished Fellow at the Harris School of Public Policy.

He began his career as a journalist, working for the Chicago Tribune. He began in politics in 1984 and founded a media and consulting firm, Axelrod and Associates.

IHT Rendezvous: Human Rights and Sports Events

Earlier this month, President Vladimir V. Putin of Russia sacked a senior Russian Olympic Committee official over rising costs and a delay in the construction work for the 2014 Winter Olympics.

Page Two

Posts written by the IHT’s Page Two columnists.

The cost of the games, to be held in the southern resort of Sochi, is expected to reach the equivalent of $50 billion. Mr. Putin said corruption had pushed up costs.

For human rights organizations, the issue is not cost or corruption. It is the principle of holding such a prestigious event in Russia as the Kremlin implements tough measures against nongovernmental organizations and clamps down on the opposition.

Why, ask human rights organizations, should Russia host such an event when even punk singers, such as some members of the Pussy Riot band, languish in prison? And why should neighboring Belarus be allowed to host the 2014 World Hockey Championships when the regime has imprisoned pro-democracy activists?

Despite the support by some political parties in Europe, human rights organizations have been unable to prevent high-profile events taking place in autocratic countries.

Last April, the Grand Prix was held in Bahrain, the subject of my latest Letter from Europe.

This was despite the fact that the regime had already imprisoned hundreds and killed at least 50 people after the short-lived Arab Spring of February 2011, according to Human Rights Watch. To this day, pro-democracy activists are detained or constantly under surveillance.

It was the same in Azerbaijan, which hosted the Eurovision Song Contest in May 2012. Human rights organizations and some European politicians had called for the event to be held elsewhere because of Azerbaijan’s appalling human rights record. The event went ahead.

A few months later, the European Football Championships were held in Poland and Ukraine. Again, there were calls by pro-democracy activists but also German politicians, to boycott the matches in Ukraine because of the continuing imprisonment of the former prime minister, Yulia Timoshenko. The matches went ahead.

Some politicians argue that it is far better to allow these events to take place in these countries. They put the spotlight on conditions there. But once the event is over, the spotlight moves elsewhere.

Maybe it is time that the international sports federations and the Olympic Committee established democracy criteria for holding such events. They will, no doubt, immediately respond that this is introducing politics into sports. But was there ever a time when sports was innocent?

Jerry Buss, Los Angeles Lakers' owner, dies at 80

LOS ANGELES (AP) — Jerry Buss, the Los Angeles Lakers' playboy owner who shepherded the NBA franchise to 10 championships from the '80s Showtime dynasty to the Kobe Bryant era, died Monday, his assistant said.

Buss died at Cedars-Sinai Medical Center in Los Angeles, said Bob Steiner, his assistant. He was 80.

He'd been hospitalized for cancer, but the immediate cause of death was kidney failure, Steiner said.

Under Buss' leadership since 1979, the Lakers became Southern California's most beloved sports franchise and a worldwide extension of Hollywood glamour. Buss acquired, nurtured and befriended a staggering array of talented players and basketball minds during his Hall of Fame tenure.

Few owners in sports history can even approach Buss' accomplishments with the Lakers, who made the NBA finals 16 times through 2011 during his 32 years in charge, winning 10 titles between 1980 and 2010. The Lakers easily are the NBA's winningest franchise since he bought the club.

Few owners have ever been more beloved by their players than Buss, who always referred to the Lakers as his extended family. Working with front-office executives Jerry West and Mitch Kupchak, Buss spent lavishly to win his titles despite lacking a huge personal fortune, often running the NBA's highest payroll while also paying high-profile coaches Pat Riley and Phil Jackson.

Always an innovative businessman, Buss paid for the Lakers through both their wild success and his own groundbreaking moves to raise revenue. He co-founded a basic-cable sports television network and sold the naming rights to the Forum at times when both now-standard strategies were unusual, adding justification for his induction into the Pro Basketball Hall of Fame in 2010.

Magic Johnson and fellow Hall of Famers Kareem Abdul-Jabbar and James Worthy formed lifelong bonds with Buss during the Lakers' run to five titles in nine years in the 1980s, when the Lakers earned a reputation as basketball's most exciting team with their glamorous Showtime style.

Jackson then led Shaquille O'Neal and Bryant to a threepeat from 2000-02, rekindling the Lakers' mystique, before Bryant and Pau Gasol won two more titles under Jackson in 2009 and 2010.

Although Buss was proudest of his two hands full of NBA title rings, he also was a scholar, Renaissance man and bon vivant who epitomized California cool — and a certain Los Angeles lifestyle — for his entire public life.

The father of six rarely appeared in public without at least one attractive, much younger woman on his arm at USC football games, boxing matches, poker tournaments — and, of course, Lakers games from his private box at Staples Center, which was built under his watch.

Buss earned a Ph.D. in chemistry at age 24 and had careers in aerospace and real estate development before getting into sports. With money largely from his Santa Monica real-estate ventures, Buss bought the then-struggling Lakers, the NHL's Los Angeles Kings and both clubs' arena — the Forum — from Jack Kent Cooke in a $67.5 million deal that was the largest sports transaction in history at the time.

In January 2011, Forbes estimated the Lakers were worth $643 million — the second-most valuable NBA franchise.

Buss also helped change televised sports by co-founding the Prime Ticket network in 1985, even receiving a star on Hollywood Walk of Fame in 2006 for his work in television. Breaking the contemporary model of subscription services for televised sports, Buss' Prime Ticket put beloved broadcaster Chick Hearn and the Lakers' home games on basic cable.

Buss also sold the naming rights to the Forum in 1988 to Great Western Savings & Loan — another deal that was ahead of its time.

Born in Salt Lake City, Gerald Hatten Buss was raised in Wyoming and attended USC for graduate school, eventually becoming a chemistry professor and working as a chemist for the Bureau of Mines before his life took an abrupt turn into wealth and sports.

The former mathematician claimed his fortune grew out of a $1,000 real-estate investment in a West Los Angeles apartment building with partner Frank Mariani, an aerospace engineer.

Buss purchased Cooke's entire Los Angeles sports empire in 1979, including a 13,000-acre ranch in Kern County. Buss' love of basketball was the motivation for his purchase, and he immediately worked to transform the Lakers — who had won just one NBA title since moving west from Minneapolis in 1960 — into a star-powered endeavor befitting Hollywood.

"One of the first things I tried to do when I bought the team was to make it an identification for this city, like Motown in Detroit," he told the Los Angeles Times in 2008. "I try to keep that identification alive. I'm a real Angeleno. I want us to be part of the community."

Buss' plans immediately worked: Johnson, Abdul-Jabbar and coach Paul Westhead led the Lakers to the 1980 title. Johnson's ball-handling wizardry and Abdul-Jabbar's smooth inside game made for an attractive style of play evoking Hollywood flair and West Coast cool.

Riley, the former broadcaster who fit the L.A. image perfectly with his slick-backed hair and chiseled good looks, was surprisingly promoted by Buss early in the 1981-82 season after West declined to co-coach the team. Riley became one of the best coaches in NBA history, leading the Lakers to four straight NBA finals and four titles, with Worthy, Michael Cooper, Byron Scott and A.C. Green playing major roles.

Overall, the Lakers made the finals nine times in Buss' first 12 seasons while rekindling the NBA's best rivalry with the Boston Celtics, and Buss basked in the worldwide celebrity he received from his team's achievements. His womanizing and partying became Hollywood legend, with even his players struggling to keep up with Buss' lifestyle.

Johnson's HIV diagnosis and retirement in 1991 staggered Buss and the Lakers, the owner recalled in 2011. The Lakers struggled through much of the 1990s, going through seven coaches and making just one conference finals appearance in an eight-year stretch despite the 1996 arrivals of O'Neal, who signed with Los Angeles as a free agent, and Bryant, the 17-year-old high schooler acquired in a draft-week trade.

Shaq and Kobe didn't reach their potential until Buss persuaded Jackson, the Chicago Bulls' six-time NBA champion coach, to take over the Lakers in 1999. Los Angeles immediately won the next three NBA titles in brand-new Staples Center, AEG's state-of-the-art downtown arena built with the Lakers as the primary tenant.

After the Lakers traded O'Neal in 2004, they hovered in mediocrity again until acquiring Gasol in a heist of a trade with Memphis in early 2008. Los Angeles made the next three NBA finals, winning two more titles.

Through the Lakers' frequent successes and occasional struggles, Buss never stopped living his Hollywood dream. He was an avid poker player, frequently participating in high-stakes tournaments, and a fixture on the Los Angeles club scene well into his 70s, when a late-night drunk-driving arrest in 2007 — with a 23-year-old woman in the passenger seat of his Mercedes-Benz — prompted him to cut down on his partying.

Buss owned the NHL's Kings from 1979-87, and the WNBA's Los Angeles Sparks also won two league titles under Buss' ownership. He also owned Los Angeles franchises in World Team Tennis and the Major Indoor Soccer League.

Buss' children moved into leadership roles with the Lakers in their father's later years. Jim Buss, the Lakers' executive vice president of player personnel and the second of Buss' six children, has taken over much of the club's primary decision-making responsibilities in the last few years, while daughter Jeanie is a longtime executive on the franchise's business side — and Jackson's longtime companion.

Yet Jerry Buss served two terms as President of the NBA's Board of Governors, and was actively involved in the 2011 lockout negotiations, developing blood clots in his legs attributed to his extensive travel during that time

Well: Certain Television Fare Can Help Ease Aggression in Young Children, Study Finds

Experts have long known that children imitate many of the deeds — good and bad — that they see on television. But it has rarely been shown that changing a young child’s viewing habits at home can lead to improved behavior.

In a study published Monday in the journal Pediatrics, researchers reported the results of a program designed to limit the exposure of preschool children to violence-laden videos and television shows and increase their time with educational programming that encourages empathy. They found that the experiment reduced the children’s aggression toward others, compared with a group of children who were allowed to watch whatever they wanted.

“Here we have an experiment that proposes a potential solution,” said Dr. Thomas N. Robinson, a professor of pediatrics at Stanford, who was not involved in the study. “Giving this intervention — exposing kids to less adult television, less aggression on television and more prosocial television — will have an effect on behavior.”

While the research showed “a small to moderate effect” on the preschoolers’ behavior, he added, the broader public health impact could be “very meaningful.”

The new study was a randomized trial, rare in research on the effects of media on children. The researchers, at Seattle Children’s Research Institute and the University of Washington, divided 565 parents of children ages 3 to 5 into two groups. Both were told to track their children’s media consumption in a diary that the researchers assessed for violent, didactic and prosocial content, which they defined as showing empathy, helping others and resolving disputes without violence.

The control group was given advice only on better dietary habits for children. The second group of parents were sent program guides highlighting positive shows for young children. They also received newsletters encouraging parents to watch television with their children and ask questions during the shows about the best ways to deal with conflict. The parents also received monthly phone calls from the researchers, who helped them set television-watching goals for their preschoolers.

The researchers surveyed the parents at six months and again after a year about their children’s social behavior. After six months, parents in the group receiving advice about television-watching said their children were somewhat less aggressive with others, compared with those in the control group. The children who watched less violent shows also scored higher on measures of social competence, a difference that persisted after one year.

Low-income boys showed the most improvement, though the researchers could not say why. Total viewing time did not differ between the two groups.

“The take-home message for parents is it’s not just about turning off the TV; it’s about changing the channel,” said Dr. Dimitri A. Christakis, the lead author of the study and a professor of pediatrics at the University of Washington.

“We want our children to behave better,” Dr. Christakis said, “and changing their media diet is a good way to do that.”

Until she began participating in Dr. Christakis’s trial, Nancy Jensen, a writer in Seattle, had never heard of shows like Nickelodeon’s “Wonder Pets!,” featuring cooperative team players, and NBC’s “My Friend Rabbit,” with its themes of loyalty and friendship.

At the time, her daughter Elizabeth, then 3, liked“King of the Hill,”a cartoon comedy geared toward adults that features beer and gossip. In hindsight, she said, the show was “hilariously funny, but completely inappropriate for a 3-year-old.”

These days, she consults Common Sense Media, a nonprofit advocacy group in San Francisco, to make sure that the shows her daughter watches have some prosocial benefit. Elizabeth, now 6, was “not necessarily an aggressive kid,” Ms. Jensen said. Still, the girl’s teacher recently commended her as very considerate, and Ms. Jensen believes a better television diet is an important reason.

The new study has limitations, experts noted. Data on both the children’s television habits and their behavior was reported by their parents, who may not be objective. And the study focused only on media content in the home, although some preschool-aged children are exposed to programming elsewhere.

Children watch a mix of “prosocial but also antisocial media,” said Marie-Louise Mares, an associate professor of communications at the University of Wisconsin, Madison. “Merely being exposed to prosocial media doesn’t mean that kids take it that way.”

Even educational programming with messages of empathy can be misunderstood by preschoolers, with negative consequences. A study published online in November in The Journal of Applied Developmental Psychology found that preschoolers shown educational media were more likely to engage in certain forms of interpersonal aggression over time.

Preschoolers observe relationship conflict early in a television episode but do not always connect it to the moral lesson or resolution at the end, said Jamie M. Ostrov, the lead author of the November study and an associate professor of psychology at the University of Buffalo.

Preschoolers watch an estimated 4.1 hours of television and other screen time daily, according to a 2011 study. Dr. Ostrov advised parents to watch television with their young children and to speak up during the relationship conflicts that are depicted. Citing one example, Dr. Ostrov counseled parents to ask children, “What could we do differently here?” to make it clear that yelling at a sibling is not acceptable.

He also urged parents to stick with age-appropriate programming. A 3-year-old might misunderstand the sibling strife in the PBS show“Arthur,” he said, or stop paying attention before it is resolved.

Disruptions: Disruptions: 3-D Printing Is on the Fast Track

Will the future be printed in 3-D?

At first glance, looking at past predictions about the future of technology, prognosticators got a whole lot wrong. The Web is a garbage dump of inaccurate guesses about the year 2000, 2010 and beyond. Flying cars, robotic maids and jet packs still are nowhere near a reality.

Yet the prediction that 3-D printers will become a part of our daily lives is happening much sooner than anyone anticipated. These printers can produce objects, even rather intricate ones, by printing thin layer after layer of plastic, metal, ceramics or other materials. And the products they make can be highly customized.

Last week, President Obama cited this nascent technology during his State of the Union address — as if everyone already knew what the technology was.

He expressed hope that it was a way to rejuvenate American manufacturing. “A once-shuttered warehouse is now a state-of-the art lab where new workers are mastering the 3-D printing that has the potential to revolutionize the way we make almost everything,” Mr. Obama said. He has pushed new technologies before, like solar and wind power, as remedies for our nation’s problems, and those attempts have only revived the debate about the limitations of government industrial policy.

But this one shows more promise. The question is, can the United States get a foothold in manufacturing one 3-D printer at a time?

Hod Lipson, an associate professor and the director of the Creative Machines Lab at Cornell, said “3-D printing is worming its way into almost every industry, from entertainment, to food, to bio- and medical-applications.”

It won’t necessarily directly create manufacturing jobs, except perhaps for the printers themselves. Dr. Lipson, the co-author of “Fabricated: The New World of 3D Printing,” said that the technology “is not going to simply replace existing manufacturing anytime soon.” But he said he believed that it would give rise to new businesses. “The bigger opportunity in the U.S. is that it opens and creates new business models that are based on this idea of customization.”

In addition to the lab that the president mentioned, a federally financed manufacturing innovation institute in Youngstown, Ohio, schools are embracing the technology. The University of Virginia has been working to introduce 3-D printers into some programs from kindergarten through 12th grade in Charlottesville to prepare students for a new future in manufacturing.

“We have 3-D printers in classrooms, and in one example, we’re teaching kids how to design and print catapults that they then analyze for efficiency,” said Glen L. Bull, professor and co-director of the Center for Technology and Teacher Education. “We believe that every school in America could have a 3-D printer in the classroom in the next few years.”

The education system may want to speed things up. The time between predictions for 3-D printers and the reality of what they can accomplish is compressing rapidly.

For example, in 2010, researchers at the University of Southern California said that another decade would pass before we could build a home using a 3-D printer. Yet last week, Softkill Design, a London architecture collective, announced that it planned to make the first such home — which it will assemble in a single day — later this year. The home isn’t that pretty, and will look more like a calcified spider web than a cozy house, but it will show it can be done. The price of 3-D printers has also dropped sharply over the last two years, with machines that once cost $20,000, now at $1,000 or less. That’s partly because Chinese companies are driving down prices. Yes, China sees the opportunity in these things, even though the technology may undermine some of its manufacturing advantages.

“When it costs you the same amount of manufacturing effort to make advanced robotic parts as it does to manufacture a paperweight, that really changes things in a profound way,” Dr. Lipson said.

This leaves us with one more question about the future: When will these 3-D printers be able to make us flying cars, robotic maids and jet packs?

IHT Rendezvous: Should Common Plastics Be Labeled Toxic?

THE HAGUE — Hoping to reduce one of the most ubiquitous forms of waste, a global group of scientists is proposing that certain types of plastic be labeled hazardous.

The group, led by two California scientists, wrote in this week’s issue of the scientific journal Nature:

We believe that if countries classified the most harmful plastics as hazardous, their environmental agencies would have the power to restore affected habitats and prevent more dangerous debris from accumulating.

While 280 million tons of plastic were produced globally last year, less than half of that plastic has ended up in landfills or was recycled, according to the scientists’ data. Some of the unaccounted for 150 million tons of plastic is still in use, but much of it litters roadsides, cities, forests, deserts, beaches and oceans. (Just think of the great floating garbage patches at sea).

Unlike other forms of solid waste, such as uneaten food, scrap metal or last year’s clothes, plastics take an especially long time to break down. And when they finally do, they create hazardous, even toxic particles that can harm wildlife, ecosystems and humans.

For now, the group — led by Chelsea M. Rochman of the School of Veterinary Medicine at the University of California, Davis, and Mark Anthony Browne at the National Center for Ecological Analysis and Synthesis in Santa Barbara, California — is calling for the reclassification of plastics that are particularly difficult to recycle and that are most toxic when degrading: PVC, polystyrene, polyurethane and polycarbonate.

The scientists say these types of plastics — used in construction, food containers, electronics and furniture — make up an estimated 30 percent of all plastics produced.

Join our sustainability conversation. Does it make sense to re-classify common plastics as hazardous, or are there better ways to reduce the amount of plastics we throw out?

Hirscher wins worlds slalom at home in Austria

SCHLADMING, Austria (AP) — Overall World Cup champion Marcel Hirscher won the men's slalom title Sunday on the last day of the skiing world championships for his first individual gold medal at a major event.

Cheered loudly by a home crowd of 35,000, the Austrian overcame the pressure of expectation to earn the host nation its second gold of the worlds, after the mixed team event.

Hirscher held onto his first-run lead to finish in a combined time of 1 minute, 51.03 seconds. Felix Neureuther of Germany was 0.41 seconds back in second. Hirscher and Neureuther are also 1-2 in the World Cup discipline standings.

Two-time former champion Mario Matt of Austria took third, 0.65 behind.

"It's awesome," Hirscher said. "I forced myself to think, 'There's nothing at stake, it's just ski racing, it's just a game.' That helped me to handle the pressure. The atmosphere was sensational, super. I had to be careful not to blow it all for them."

Hirscher missed the 2011 worlds because of a broken foot. On Thursday, he injured his back and neck during training but finished second to Ted Ligety in GS the next day and followed it up with Sunday's win. It was the 14th gold in slalom for Austria.

His father and coach, Ferdinand Hirscher, called it "a wonderful day."

"It was very tense as we had to change something on the setup of his boots this morning," Ferdinand said. "But Marcel always stays cool. He tries not to think about titles and championships. He just concentrates on the information the coaches are giving him before a run."

Italian great Alberto Tomba said the Austrian's achievement was "super, super."

"I said three days ago, Marcel is going to win," said Tomba, the 1996 world slalom champion. "It's super he's done it. Felix and Mario were also great."

Ligety, a three-time champion, failed to finish when the American lost his balance and his left boot clicked out of the bindings 15 seconds into his run.

Olympic winner Giuliano Razzoli of Italy skied out on the bottom part in his first run, and defending world champion Jean-Baptiste Grange of France finished 2.43 off the lead in 12th place.

Neureuther, who trailed Hirscher by 0.28 after the first run, won his first individual medal at a major competition.

"It's fantastic," Neureuther said. "I usually try to hide my emotions but I can't do that now. I've finally done what I've tried to do many times before at big events. I am really happy and proud."

Neureuther helped Germany win bronze in the team event. Maria Hoefl-Riesch, who won the women's super-combined title, added two more medals for Germany.

"Everybody was talking about this duel: Marcel vs. Felix — and that's what it was," Neureuther said. "I just tried to avoid the mistakes I made at other championships."

Matt won the world slalom title in 2001 at home and again in 2007. He led the race briefly after a strong second run but was overtaken by both Neureuther and Hirscher.

"You have to fully attack but avoid making it a useless run," Matt said. "I lost a bit of time with a small mistake on the bottom, but I have to be satisfied with bronze."

The course caused many racers problems as mild temperatures softened the top layer of snow.

"The snow felt weird," Hirscher said, and Neureuther added it was "extremely difficult to gain speed on this course. You just don't get the right feeling on it."

Ligety's attempt to win a fourth medal failed shortly after starting his first run.

"I just kind of made a mistake," Ligety said. "I wanted to go really hard forward on the ski and I just peeled it right out of the back of the binding."

Ligety, who also captured the super-G and super-combined titles, could have equaled the 45-year record held by French great Jean-Claude Killy, who won four golds in 1968.

Ligety helped the United States top the medals table, even without Lindsey Vonn, who suffered a season-ending knee injury in the opening race. Mikaela Shiffrin added another gold in the women's slalom, and Julia Mancuso took bronze in super-G.

"It was an awesome world champs," Ligety said. "Of course it was a bummer to go out in the slalom. I just had the ski peel off again, which has been happening this year ... I feel pretty good for the most part. I'm not at the level of consistency of Hirscher or Felix, but I still feel like I have good speed relative to those guys. I just don't put together runs like those guys do."

Ligety's teammates David Chodounsky and Will Brandenburg also failed to finish the opening run.
