J. Richard Hackman, an Expert in Team Dynamics, Dies at 72





J. Richard Hackman, a Harvard psychology professor whose fieldwork sometimes took him to the cockpit of an airliner to observe the crew in a nearly five-decade quest to determine the dynamics of teamwork and effective leadership, died on Jan. 8 in Boston. He was 72.




The cause was lung cancer, his wife, Judith Dozier Hackman, said.


Dr. Hackman, the author or co-author of 10 books on group dynamics, was the Edgar Pierce professor of social and organizational psychology at Harvard.


In one of his best-known books, “Leading Teams: Setting the Stage for Great Performances” (2002), he replaced the popular image of the powerful “I can do it all” team leader with that of someone who, as he wrote, had the subtle skills “to get a team established on a good trajectory, and then to make small adjustments along the way to help members succeed.”


The conditions for a successful team effort — among them “a compelling direction, an enabling team structure, a supportive organizational context and expert team coaching” — “are easy to remember,” Dr. Hackman wrote.


“The challenge,” he continued, “comes in developing an understanding of those conditions that is deep and nuanced enough to be useful in guiding action, and in devising strategies for creating them even in demanding or team-unfriendly organizational circumstances.”


Besides tracking the interplay of pilots, co-pilots and navigators aboard civilian and military planes, Dr. Hackman observed corporate boards, sports teams, orchestra players, telephone-line repair crews, hospital workers and restaurant kitchen staff members.


And in recent years, for his 2011 book, “Collaborative Intelligence,” he was allowed to observe interactions within the American intelligence, defense, law-enforcement and crisis-management communities.


“Although my main aspiration has been to provide guidance that will be useful to team leaders and members,” he wrote, “there are no ‘one-minute’ prescriptions here — creating, leading and serving on teams is not that simple.”


Anita Woolley, a professor of organizational behavior and theory at the Tepper School of Business at Carnegie Mellon University in Pittsburgh, said, “The key thing about Dr. Hackman’s work is that it stands in contrast to some of the more popular models of leadership that focused very much on style or how leaders behave, versus what they do.”


Rather than viewing pay as a prime motivator for good performance, she continued, “he focused on features of people’s jobs that made them more intrinsically satisfied: the freedom to determine how they conduct their work, having a variety of tasks, having knowledge of the ultimate outcomes of their work, knowing how their work affects or is received by other people.”


He also liked to overturn some of the received wisdom about teamwork. In a 2011 article for The Harvard Business Review, Dr. Hackman listed “Six Common Misperceptions About Teamwork.” Among them was this:


“Misperception No. 2: It’s good to mix it up. New members bring energy and fresh ideas to a team. Without them, members risk becoming complacent, inattentive to changes in the environment, and too forgiving of fellow members’ misbehavior.


“Actually: The longer members stay together as an intact group, the better they do. As unreasonable as this may seem, the research evidence is unambiguous. Whether it is a basketball team or a string quartet, teams that stay together longer play together better.”


John Richard Hackman was born in Joliet, Ill., on June 14, 1940, the only child of J. Edward and Helen Hackman. His father was an oil pipeline engineer, his mother a schoolteacher.


Dr. Hackman received a bachelor’s degree in mathematics from MacMurray College in Jacksonville, Ill., in 1962, and a doctorate in psychology from the University of Illinois in 1966. He soon joined the psychology and administrative sciences department faculties at Yale, where he taught until 1986, when he moved to the psychology and business departments at Harvard.


Besides his wife, who is an associate dean at Yale, he is survived by two daughters, Julia Beth Proffitt and Laura Dianne Codeanne, and four grandchildren.


After Dr. Hackman died, The Harvard Crimson wrote that for years he had “devoted countless hours to improving one team in particular — the Harvard women’s basketball squad, for which he volunteered as an honorary coach.”

China's smog taints economy, health









BEIJING — When a thick quilt of smog enveloped swaths of China earlier this month, it set in motion a costly chain reaction for the world's No. 2 economy.


Authorities canceled flights across northern China and ordered some factories shut. Hospitals were flooded with hacking patients.


A fire in an empty furniture factory in eastern Zhejiang province went undetected for hours because the smoke was indistinguishable from the haze. In coastal Shandong province, most highways were closed for fear that low visibility would cause motorists to crash. And in Beijing, the local government urged residents to remain indoors and told construction sites to scale back activity.








Photos: Smog in China


"These are emergency measures that have the same economic impact as a strike or severe weather," said Louis Kuijs, a Hong Kong-based economist with the Royal Bank of Scotland and formerly of the World Bank. "They're very painful."


Residents in the capital have taken to mocking their famously filthy air and its attendant health hazards with the expression "Beijing cough." Meanwhile, Shanghai's Environmental Protection Bureau has introduced a cartoon mascot to communicate daily air quality on its website: a pig-tailed girl who bursts into tears when smog reaches hazardous levels.


But economists say China's smog is no joke. As air pollution continues to obscure China's cities, the cost to the nation in lost productivity and health problems is soaring. The World Bank estimates sickness and early death sapped China of $100 billion in 2009, or just under 3% of gross domestic product. China is now home to seven of the 10 most-polluted cities in the world, according to a report by the Asian Development Bank and Beijing's Tsinghua University.


A study by Greenpeace and Peking University's School of Public Health put the cost of healthcare to treat pollution-related ailments in Beijing, Shanghai, Guangzhou and Xian at more than $1 billion last year.


Beijing resident Zhang Jian takes his 2-year-old son to a doctor regularly to treat the toddler's chronic sinus infection.


"It's definitely related to the pollution," said Zhang, 35, who wore a disposable mask at an overcrowded children's hospital recently. "My son snores and his nose is blocked constantly. It's a problem because he's too young to clear his nose like adults."


The doctor's visit and treatment cost Zhang about $320 — nearly a week's pay for the IT professional.


The Beijing government says it's considering a host of emergency measures to clear the air. Among them: limiting vehicle usage, spraying building sites to reduce dust and restricting outdoor barbecue grills.


Even China's next premier, Li Keqiang, weighed in recently on the issue. "This is a problem accumulated over a long period of time, and solving the problem will also require a long time. But we need to take action."


China's smog crisis is not unlike those experienced in London and Los Angeles in the 1950s. Public outcry ultimately led to cleaner air and tougher environmental regulations.


Environmental activists hope the same happens in China. The official response in recent weeks has raised optimism that authorities will begin addressing pollution more openly.


Until recently, state media was loathe to use the word "pollution," opting instead for the euphemism "fog."


But popular pressure is building, making it harder for policymakers to ignore the foul air in many of China's largest cities.


After the staggeringly bad bout of air pollution in the middle of this month, micro-bloggers took to posting pictures of themselves online wearing masks.


Some held handwritten signs that read, "I don't want to be a human vacuum cleaner."


The phrase became the top-trending topic on the Twitter-like Sina Weibo, attracting several million hits.

Crazy Alien Weather: Lightning-Filled Rocket Dust Storms of Mars



Scientists have modeled the internal workings of lightning-filled “rocket dust storms” on Mars that rise at speeds 100 times faster than ordinary storms and inject dust high into the Martian atmosphere.


The Red Planet is a very dry and dusty place, with global storms that sometimes obscure the entire surface. Satellites orbiting Mars have seen persistent dust layers reaching very high altitudes, as much as 30 to 50 km above the ground, though scientists are at a loss to explain exactly how the dust got there.


Using a high-resolution model, researchers have shown that a thick blob-like dust pocket inside a storm may become heated by the sun, causing the surrounding atmosphere to warm quickly. Because hot air rises, these areas will shoot skyward super fast, much like a rocket launching into space, hence “rocket dust storms.”


“The vertical transport was so strong we want to come up with a kind of spectacular name, to give an idea of the very powerful rise,” said planetary scientist Aymeric Spiga from the Institut Pierre Simon Laplace in Paris, France, who is lead author on a paper describing the phenomena in the Journal of Geophysical Research: Planets on Jan. 14.



These speedily rising dust blobs can soar from near the surface to 30 or 40 km into the atmosphere in a matter of hours at speeds in excess of 10 meters per second (22 mph). This is far faster than the typical convection speeds in a dust storm of 0.1 meters per second (0.2 mph). Since the dust particles rub up against one another and create friction, the rocket dust storms may become charged with electrostatic forces, which could which could trigger fantastic lightning bolts.


Spiga and his team used detailed models of winds and dust on Mars to determine exactly how these rocket dust storms behave. Most previous models of Mars’ climate simulate large-scale global dust storms with fairly coarse resolution and so have not noticed the rocket storms. The team seeded their model with data from a dust storm observed by the OMEGA instrument aboard ESA’s Mars Express orbiting satellite and watched the rise of rocket storms.



Similar dust storms can’t happen on Earth. This is mainly because Mars’ atmosphere is about 100 times thinner than our own, meaning that it gets quickly and efficiently heated when dust particles absorb sunlight and then emit thermal radiation.


But a comparable phenomenon occurs in grey cumulonimbus thunderstorm clouds on Earth. The large accumulations of water particles in such clouds release latent heat, causing strong vertical motions and an extensive tall structure. Spiga’s team has used this Earthly analogy in the rocket dust storm’s more technical name, conio-cumulonimbus, from the Greek conious, which means dust.


“But I prefer to call them rocket dust storms,” Spiga said. “Then everyone knows what I’m talking about.”


Other researchers are impressed with the physical modeling done in the work. “I was a little surprised that such a small dust disturbance could remain intact over such long distances,” said planetary atmospheres scientist Scot Rafkin from the Southwest Research Institute in Boulder, Colorado. The mechanism could help explain how long-lasting layers of dust climb so high in the Martian atmosphere, he says. 


Because they appear to be relatively rare, it may take a while to track down more rocket dust storms. But Spiga is hopeful they will be found by orbiting satellites, which may even image the lightning flashes inside them.

Fox News, Palin cutting ties






NEW YORK (AP) — Fox News Channel is parting ways with former Republican vice presidential candidate Sarah Palin, ending her three-year tenure as a contributor on the network.


While Palin’s time at Fox was occasionally rocky, the network’s news executive, Bill Shine, said Friday that “we have thoroughly enjoyed our association” with her.






“We wish her the best in her future endeavors,” said Shine, Fox’s executive vice president for programming.


A person familiar with discussions between Fox and Palin described the parting as amicable, saying that Fox and Palin had discussed renewing her contract but she decided to do other things. The person spoke on condition of anonymity because they were not authorized to speak on the record.


Palin’s lawyer in Alaska, John Tiemessen, had no immediate comment on her exit. Palin’s last appearance on Fox News was Dec. 19 on Greta Van Susteren‘s show.


Palin signed to deliver commentary on Fox in January 2010, reportedly for $ 1 million a year. It was a coup for both sides at the time; the former Alaska governor was a little more than a year removed from her attention-getting run for the vice presidency and was considered one of the leading contenders for the 2012 presidential nomination. At Fox, she had a platform on the most popular network for conservative viewers. Fox installed equipment in Palin’s Wasilla, Alaska, home to make her regular appearances easier.


But there were some indications of tension between her and Fox News Chairman Roger Ailes, who was quoted in a 2011 story by The Associated Press saying, “I hired Sarah Palin because she was hot and got ratings.”


When Palin announced she would not be a candidate in 2012, she said it on a conservative radio show, which didn’t sit well with the company paying her to be a contributor. Palin took to her Facebook page late last summer to complain that Fox had cancelled her appearances one night at the GOP national convention; Fox said it was simply because the GOP had to condense its speaker schedule due to a hurricane.


Four years removed from her vice presidential candidacy, Palin’s influence had waned and she was somewhat overshadowed as a contributor at Fox by Karl Rove, former President George W. Bush‘s top political aide. Rove recently renewed his contract at Fox through the 2016 election.


With four more years of a Barack Obama administration in power, Fox recently hired former Democratic presidential candidate Dennis Kucinich as a contributor.

40 Years After Roe v. Wade, Thousands March to Oppose Abortion


Drew Angerer/The New York Times


Pro-life activists made their way down Constitution Avenue toward the Supreme Court during the March for Life in Washington on Friday.







WASHINGTON — Three days after the 40th anniversary of the decision in Roe v. Wade, the landmark Supreme Court case that legalized abortion, tens of thousands of abortion opponents from around the country came to the National Mall on Friday for the annual March for Life rally, which culminated in a demonstration in front of the Supreme Court building.




On a gray morning when the temperature was well below freezing, the crowd pressed in close against the stage to hear more than a dozen speakers, who included Tony Perkins, the president of the Family Research Council; Representative Diane Black, Republican of Tennessee, who recently introduced legislation to withhold financing from Planned Parenthood, and Senator Rand Paul, Republican of Kentucky; Cardinal Seán Patrick O’Malley of Boston; and Rick Santorum, the former senator from Pennsylvania and Republican presidential candidate.


Mr. Santorum spoke of his wife’s decision not to have an abortion after they learned that their child — their daughter Bella, now 4 — had a rare genetic disorder called Trisomy 18.


“We all know that death is never better, never better,” Mr. Santorum said. “Bella is better for us, and we are better because of Bella.”


Jeanne Monahan, the president of the March for Life Education and Defense Fund, said that the march was both somber and hopeful.


“We’ve lost 55 million Americans to abortion,” she said. “At the same time, I think we’re starting to win. We’re winning in the court of public opinion, we’re winning in the states with legislation.”


Though the main event officially started at noon, the day began much earlier for the participants, with groups in matching scarves engaged in excited chatter on the subway and gaggles of schoolchildren wearing name tags around their necks. Arriving on the Mall, attendees were greeted with free signs (“Defund Planned Parenthood” and “Personhood for Everyone”) and a man barking into a megaphone, “Ireland is on the brink of legalizing abortion, which is not good.”


The march came two months after the 2012 campaign season, in which social issues like abortion largely took a back seat to the focus on the economy. But the issue did come up in Congressional races in which Republican candidates made controversial statements about rape or abortion. In Indiana, Richard E. Mourdock, a Republican candidate for the Senate, said in a debate that he believed that pregnancies resulting from rape were something that “God intended,” and in Illinois, Representative Joe Walsh said in a debate that abortion was never necessary to save the life of the mother because of “advances in science and technology.” Both men lost, hurt by a backlash from female voters.


Recent polls show that while a majority of Americans do not want Roe v. Wade to be overturned entirely, many favor some restrictions. In a Gallup poll released this week, 52 percent of those surveyed said that abortions should be legal only under certain circumstances, while 28 percent said they should be legal under all circumstances, and 18 percent said they should be illegal under all circumstances. In a Pew poll this month, 63 percent of respondents said they did not want Roe v. Wade to be overturned completely, and 29 percent said they did — views largely consistent with surveys taken over the past two decades.


“Most Americans want some restrictions on abortion,” Ms. Monahan said. “We see abortion as the human rights abuse of today.”


Speaker John A. Boehner of Ohio, who spoke via a recorded video, called on the protest group, particularly the young people, to make abortion “a relic of the past.”


“Human life is not an economic or political commodity, and no government on earth has the right to treat it that way,” he said.


The crowd was dotted with large banners, many bearing the names of the attendees’ home states and churches and colleges. Gary Storey, 36, stood holding a handmade sign that read “I was adopted. Thanks Mom for my life.” Next to him stood his adoptive mother, Ellen Storey, 66, who held her own handmade sign with a picture of her six children and the words “To the mothers of our four adopted children, ‘Thank You’ for their lives.”


Mr. Storey said he was grateful for the decision by his biological mother to carry through with her pregnancy. “Beats the alternative,” he joked.


Last week, the Planned Parenthood Federation of America started a new Web site, and on Tuesday, its president, Cecile Richards, released a statement supporting abortion rights.


“Planned Parenthood understands that abortion is a deeply personal and often complex decision for a woman to consider, if and when she needs it,” she said. “A woman should have accurate information about all of her options around her pregnancy. To protect her health and the health of her family, a woman must have access to safe, legal abortion without interference from politicians, as protected by the Supreme Court for the last 40 years.”


This article has been revised to reflect the following correction:

Correction: January 25, 2013

A summary that appeared on the home page of NYTimes.com with an earlier version of this article misstated the day of the march. It took place on Friday, not Thursday.

Labor Relations Board Rulings Could Be Undone



By ruling that Mr. Obama’s three recess appointments last January were illegal, the federal appeals court ruling, if upheld, would leave the board with just one member, short of the quorum needed to issue any rulings. The Obama administration could appeal the court ruling, but no announcement was made on Friday.


If the Supreme Court were to uphold Friday’s ruling, issued by the United States Court of Appeals for the District of Columbia Circuit, it would mean that the labor board did not have a quorum since last January and that all its rulings since then should be nullified.


Many Republicans and business groups applauded Friday’s ruling. They often assert that the appointments Mr. Obama made to the board have transformed it into a tool of organized labor. But many Democrats and labor unions say Mr. Obama’s appointments restored ideological balance to the board after it was tipped in favor of business interests under President George W. Bush


Mark G. Pearce, the board’s chairman, issued a statement saying the board disagreed with the ruling and suggested that other appeals courts hearing cases about the constitutionality of Mr. Obama’s appointments could reach a different conclusion.


“In the meantime, the board has important work to do,” said Mr. Pearce, whose agency oversees enforcement of the laws governing strikes and unionization drives. “We will continue to perform our statutory duties and issue decisions.”


Unless the Senate confirms future nominees to the board — Senate Republicans have blocked several of Mr. Obama’s board nominees — Mr. Pearce will be the only member left if Friday’s ruling is upheld. The board has five seats.


Representative Darrell Issa, a California Republican who is the chairman of the Oversight and Government Reform Committee, issued a statement that urged the recess appointees to “do the right thing and step down.” He added, “To avoid further damage to the economy, the N.L.R.B. must take the responsible course and cease issuing any further opinions until a constitutionally sound quorum can be established.”


The three disputed recess appointees included two Democrats, Sharon Block, deputy labor secretary, and Richard Griffin, general counsel to the operating engineers’ union; and one Republican, Terence Flynn, a counsel to a board member. Mr. Flynn resigned last May after being accused of leaking materials about the group’s deliberations. Another Republican member, Brian Hayes, stepped down when his term expired last month.

Palmdale woman accused of torturing her children









Neighbors of a Palmdale woman charged with assaulting and torturing two of her children said Thursday that they never even realized she had kids.


The siblings — a boy, 8, and girl, 7 — did not play outside and were rarely seen, said Cynthia Otero, who runs a day care center at a home opposite the house in the 39000 block of Clear View Court where Ingrid Brewer is alleged to have mistreated the youngsters.


Otero said that when she recently spotted the children getting out of a car, she thought Brewer, 50, "might be baby-sitting."








So neighbors in the suburban cul-de-sac were the more shocked when word spread that Brewer was arrested on suspicion of crimes against her children, she said. Brewer is being charged with eight felony counts, including torture, assault with a deadly weapon and cruelty to a child.


According to authorities, Brewer reported the children missing Jan. 15, prompting a search by deputies from the Los Angeles County Sheriff's Palmdale Station. The youngsters were found hours later hiding under a blanket near a parked car on a street close to their home. They were without winter clothes in 20-degree weather, authorities said.


Sgt. Brian Hudson, a spokesman for the sheriff's Special Victims Bureau, said the children told investigators they ran away because Brewer deprived them of food, locked them in separate bedrooms when she went to work each day, bound their hands behind their backs with zip ties and beat them with electrical cords and a hammer. The youngsters also said that when they were locked in the bedrooms and needed to use the bathroom, they instead had to use wastebaskets, Hudson said.


They fled because "they were tired of being tied up and beaten," Hudson said.


Hudson said both children had injuries consistent with the alleged abuse, including marks on their wrists indicating they had been restrained and "numerous bruising and abrasions over their bodies." They told investigators the mistreatment had been happening since Halloween.


Neighbors interviewed by authorities said they had never noticed anything suspicious but "hardly ever saw the two children," Hudson said. Otero and another neighbor said Brewer did not make friends on the block.


Otero said Brewer was "unfriendly" and typically ignored verbal greetings and waves.


According to sheriff's officials, Brewer, a certified nursing assistant who works in Los Angeles and has adult children, adopted the young siblings about a year ago from foster care. They were home schooled.


Neil Zanville, a spokesman for the county Department of Children and Family Services, said his agency was legally prohibited from disclosing any case-specific information about past or present clients. But in a written statement, the agency's director, Philip Browning, called the report disturbing.


"While we cannot confirm or deny whether this family is under our supervision, I am personally looking into this situation to determine what role, if any, our department had in these children's lives," Browning said.


Sheriff's officials said Thursday that the children were "doing great" despite their injuries.


Otero lamented that they had been made to suffer.


"It's just so sad," said the neighbor, who has a 5-year-old daughter and 8-year-old twins. "I wish they would have knocked on my door. I would have helped them."


Brewer is in the custody of the Sheriff's Department, with bail set at $2 million. She is scheduled to appear in court Thursday, Hudson said.

The Truth About Weight-Loss Pills and Energy Drinks, for Knowledge and Profit



Between medications and food, there’s a huge swath of edible products that don’t need approval from the Food and Drug Administration, including energy drinks, vitamins, weight-loss pills, and other supplements. And while the companies that make those goods test their products for safety, they don’t usually offer test results that vouch for efficacy or mention the less savory ingredients that often lurk inside their pills and potions. Which leaves most of us wandering the aisles of GNC wondering if everything on the shelves is safe, or has a fraction of the miraculous powers claimed.


To determine whether that jug of protein power is really worth the cash, Neil Thanedar just launched LabDoor. LabDoor tests a wide variety of energy-granting, and muscle-building concoctions and grades them on safety, clinical efficacy, and the presence of potentially unhealthy ingredients including heavy metals, pesticides, and other unsavory trace elements. Thanedar dreamed up the idea for the startup when, while running a product-testing lab, his friends would regularly ask his professional chemist’s opinion on the latest energy drink, muscle-building concoction or weight loss pill.


LabDoor opened up its service to the public this week, starting with testing the most popular energy drinks and vitamins on the market, including Red Bull, Five Hour Energy , One-A-Day and Centrum vitamins among others. “Next we’ll test creatine powders, sleep aides, and herbal supplements,” Thanedar says. “Eventually we want to add cosmetics and over-the-counter medications, so you can find out if there’s really a (quality) difference between a generic painkiller and Tylenol.” For example, what exactly is that carnuba wax doing in your generic ibuprofen? “If you look at painkillers and muscle gain supplements and powders, most manufacturers tell you what’s in them,” says Thanedar. “But even if you read the label, you still wouldn’t understand what those ingredients do.”



To keep results rooted in the real-world, LabDoor goes out and buys off-the-shelf samples of products and takes them back to their Indianapolis, Indiana lab for testing. Each product gets a grade (from A to F) based on the lab results, and clinical studies on the main ingredients from the National Institute of Health and other medical research groups.


Some of the results are already in. LabDoor gives the energy shot Redline Power Rush 7hr Energy a D+ grade because it has an enormously high level of caffeine per ounce. “A shot is 11 times more potent per ounce than a Red Bull,” Thanedar says. “If you don’t know that, you could end up taking two or three shots per day without realizing how much caffeine you’re consuming.” The popular cold fighter Airborne grabbed a C+ because studies have shown it’s not clinically effective, though the ingredients are safe according to lab tests. Regular Redbull gets an overall B for safety and efficacy.


LabDoor has a website and iOS app, with plans to launch an Android app as the database of products grows. Thanedar is keeping the overall grade, clinical efficacy, and ingredient safety information free for anyone to view, but is working on a paid subscription service that will show an image of the product’s label and provide a more detailed breakdown of the ingredients in it and their effects.


The goal, Thanedar says, is to shine a light on all those questionable ingredients and eventually encourage manufacturers to be more transparent. Maybe the next time you and your biceps are shopping for protein powder, you’ll know exactly what you’re getting.

Voice of Te’o prankster? Couric plays voicemails






NEW YORK (AP) — The person Manti Te’o says was pretending to be his online girlfriend told the Notre Dame linebacker “I love you” in voicemails that were played during his interview with Katie Couric.


Taped earlier this week and broadcast Thursday, the hour-long talk show featured three voicemails that Te‘o claims were left for him last year. Te’o said they were from the person he believed to be Lennay Kekua, a woman he had fallen for online but never met face-to-face.






After the first message was played, Te’o said: “It sounds like a girl, doesn’t it?”


“It does,” Couric responded.


The interview was the All-American’s first on camera since his tale of inspired play after the deaths of his grandmother and girlfriend on the same day in September unraveled as a bizarre hoax in an expose by Deadspin.com on Jan. 16.


Te’o's parents appeared with him for part of the interview and backed up his claim that he wasn’t involved in the fabrication, saying they, too, had spoken on the phone with a person they believed to be Kekua.


Couric addressed speculation that the tale was concocted by Te’o as a way to cover up his sexual orientation. Asked if he were gay, Te’o said “no” with a laugh. “Far from it. Faaaar from that.”


He also said he was “scared” and “didn’t know what to do” after receiving a call on Dec. 6 — two days before the Heisman Trophy presentation — from a person who claimed to be his “dead” girlfriend.


The first voicemail, he said, was from what was supposed to be Kekua’s first day of chemotherapy for leukemia.


“Hi, I am just letting you know I got here and I’m getting ready for my first session and, um, just want to call you to keep you posted. I miss you. I love you. Bye,” the person said.


In the second voicemail, the person was apparently upset by someone else answering Te’o's phone.


The third voicemail was left on Sept. 11, according to Te’o, the day he believed Kekua was released from the hospital and the day before she “died.”


“Hey babe, I’m just calling to say goodnight,” the person on the voicemail said. “I love you. I know that you’re probably doing homework or you’re with the boys. … But I just wanted to say I love you and goodnight and I’ll be ok tonight. I’ll do my best. Um, yeah, so get your rest and I’ll talk to you tomorrow. I love you so much, hon. Sweet dreams.”


Couric suggested the person who left those messages might have been Ronaiah Tuisasosopo, a 22-year-old man from California, who Te’o said has apologized to him for pulling the hoax.


“Do you think that could have been a man on the other end of the phone?” she asked.


“Well, it didn’t sound like a man,” Te’o said. “It sounded like a woman. If he somehow made that voice, that’s incredible. That’s an incredible talent to do that. Especially every single day.”


Tuiasosopo has not spoken publicly since news of the hoax broke. The Associated Press has learned that a home in California where Te’o sent flowers to the Kekua family was once a residence of Tuiasosopo and has been in his family for decades.


Also on Thursday, the woman whose pictures were used in fake online accounts for Kekua said Tuiasosopo confessed to her in a 45-minute phone conversation as the scheme unraveled.


Diane O’Meara spoke with The Associated Press in a telephone interview. She said Tuiasosopo told her he’d been “stalking” her Facebook profile for five years and stealing photos.


O’Meara’s attorney, Jim Artiano, said they had not decided on whether to take any legal action.


The 23-year-old O’Meara, of Long Beach, Calif., said she knew Tuiasosopo from high school and he contacted her through Facebook on Dec. 16. She said that, over the next three weeks, Tuiasosopo got in touch with her several times, attempting to get photos and video of O’Meara. She said he made up a story about wanting them to help cheer up a cousin who was injured in a car crash.


O’Meara learned her identity had been stolen on Jan. 13 when she was contacted by Deadspin.com.


The next day she got in touch with Tuiasosopo.


“When I contacted Ronaiah I got a very bizarre vibe from him, he became very nervous, he wasn’t asking the questions I expected. He was asking ‘Who contacted you? What did they say?’” O’Meara said.


Later that day, he confessed, O’Meara said. She said she asked Tuiasosopo why he didn’t simply stop the hoax.


“He told me he wanted to end the relationship,” O’Meara said. “He said he wanted to stop the relationship between Lennay and Manti, but Manti didn’t want Lennay to break up with him … He said he tried to stop the game many times.”


When news of the hoax broke a few days later, O’Meara said she received a text from Tuiasosopo asking her to call him as soon as possible. O’Meara said she didn’t respond.

The New Old Age Blog: Time to Recognize Mild Cognitive Disorder?

The Diagnostic and Statistical Manual of Mental Disorders, published and periodically updated by the American Psychiatric Association, is one of those documents few laypeople ever read, but many of us are affected by.

It can make it easier or harder to get an insurance company or Medicare to cover treatments, for example. It factors into a variety of legal and governmental decisions.

And on a personal basis, a psychiatric diagnosis may be welcome (having a name and a treatment plan for what’s bothering us can be comforting) or not (are we really suffering from a mental disorder if we seem depressed after a family member dies?).

That last question refers to a change in the new DSM5, to be published in May, that has generated considerable controversy and that I discussed in an earlier post: the removal of the “bereavement exclusion,” once part of the diagnosis of major depressive disorder.

Another element of the revised D.S.M. could also affect readers: It will include something called mild neurocognitive disorder. The task force revising the manual wanted to align psychiatry with the rest of medicine, which has already begun to distinguish between levels of impairment, said its chairman, Dr. David J. Kupfer, a University of Pittsburgh psychiatrist.

True enough, as we have reported before. Neurologists call it mild cognitive impairment, a stage where cognitive decline becomes noticeable enough to affect daily functioning, yet people can still live independently and have not progressed to dementia.

In fact, a large proportion of people with mild cognitive problems never will develop dementia — but doctors and researchers cannot yet determine who will and who won’t. Biomarkers that could identify the biological brain changes that presage dementia are still years away.

Will it be helpful, then, for health professionals using the DSM5 — most of them not psychiatrists, but primary care doctors — to begin diagnosing mild neurocognitive disorder? Particularly as there is no treatment that can reverse it or reliably slow its progression, if it would progress?

Dr. Ronald Petersen, director of the Mayo Clinic’s Alzheimer’s Disease Research Center and a member of the working group that developed the new DSM5 criteria, said he thought the newly recognized disorder would be useful. “The predementia phase is becoming increasingly important,” he told me in an interview.

Counseling could help people compensate for the memory loss and other deficits they are experiencing, for example. With a D.S.M.-recognized diagnosis, those approaches are more likely to be covered by insurers.

Besides, “one argument against Alzheimer’s therapies is that we wait too late, when there’s too much damage to the central nervous system to repair,” Dr. Petersen said, referring to several recent disappointing drug trials. In the future, with earlier diagnoses, “you may be able to intervene, stop the process and forestall the dementia.”

But as we have seen with screening tests for other diseases, early detection does not always lead to better health or longer lives. It can, however, lead to unnecessary treatments and procedures involving risks of their own. Could that happen with mild neurocognitive disorder?

“It will lead to wild overdiagnosis,” predicted Allen Frances, an emeritus professor of psychiatry at Duke and the chairman of the task force that developed the previous D.S.M. edition. Indeed, about a quarter of people initially diagnosed with mild cognitive impairment are later determined to be normal, a prominent researcher told my colleague Judith Graham last year.

“People will get unnecessary tests and start getting weird treatments that have no proven efficacy,” said Dr. Frances, who has criticized a number of DSM5 changes. “They’re going to worry like crazy about being demented.”

Dr. Petersen agreed that it was a legitimate concern, but “by and large, we’re becoming better at distinguishing between the normal cognitive effects of aging and disease.” (The American Psychiatric Association will publish a specialized D.S.M. for primary care physicians, Dr. Kupfer pointed out, to help guide them through diagnoses.)

It is hard for patients and families to know how to react when experts disagree. But keep in mind that contemporary health care aims for what is called shared decision-making. That means patients and professionals discuss options and weigh the risks and benefits of treatments and procedures, their likely outcomes, patients’ preferences, and come to agreement on how to proceed. This essay in the New England Journal of Medicine calls shared decision-making “the pinnacle of patient-centered care.”

So when Dr. Frances refers to the DSM5 as “a guide, not a bible,” and urges skepticism about some of its diagnoses, he is advocating an approach that patients and families should probably bring to any medical decision.

Seeking further information, asking questions, assessing options — those are reasonable responses if, a few weeks after a loved one’s death, a doctor says you may have major depression. Or if she thinks your memory loss could mean mild neurocognitive disorder.

“The shorter the evaluation, the less the person knows you, the less he or she can explain and justify the diagnosis, the more tests and treatments that will result, the more a person should be cautious and get a second opinion,” Dr. Frances said.

Whatever the DSM5 says, it’s hard to argue with that.
