Rules to simplifying life come up short

Los Angeles-area author Matthew E. May has hit upon an attractive theme in his recent book, "The Law of Subtraction: 6 Simple Rules for Winning in the Age of Excess Everything" published by McGraw-Hill.

Who does not yearn for a guide to simplifying, synthesizing and subtracting some of the clutter, overload and demands of the "Age of Excess Everything"?

He has also cleverly subtracted from his own workload by inviting others, mostly authors and consultants like him, to contribute about a third of the material for his six laws for doing more with less in the form of summaries of their views.

Mind you, it took fellow author Daniel Pink to point out the appeal of the subject. "Subtraction is your meme. It's out there; it's growing," he told May just before he took the stage at a corporate conference, urging him to "own" it. "Best. Advice. Ever," writes May.

This exchange is itself a little guide to what the book is like. Not only is it full of people talking in a slightly artificial, visionary way about common sense objectives, it is also filled with contradictions. "Subtraction is growing" is only the first.

The book does contain good examples of the less-is-more theme, some well-known, some less so. May's opener (illustrating Law No. 1: "What isn't there can often trump what is") is the FedEx logo, featuring an arrow created by the blank space between the E and X. Lindon Leader, its designer, explains how he "didn't overplay it, didn't mention it" when pitching the idea. (He makes up for that here.)

May, who lives in Westlake Village, also provides a brief history of how Lockheed Corp. put a team of design engineers in a circus tent next to a foul-smelling plastics factory to design a jet fighter: the secret Skunk Works became a byword for how to foster innovation. (Law No. 5: "Break is the important part of breakthrough.")

He cites J.K. Rowling, who was inspired for the idea for Harry Potter on a long, boring train journey, in support of Law No. 6. ("Doing something isn't always better than doing nothing.").

My favorite came from contributor Bob Harrison, a retired police chief, who introduced an "unplan" to withdraw officers directing traffic after a July 4 fireworks display and discovered everyone got home more quickly. (Law No. 2: "The simplest rules create the most effective experience.")

But I find every subtractive success story has an additive counterweight, some of which are explicit in May's examples.

It is true that "creativity thrives under intelligent constraints" (Law No. 4), but Michelangelo — ordered to work on a fresco for the Sistine Chapel, not a sculpture, his preferred medium — then "expanded the job's scope," covering the walls as well as the ceiling.

Steve Jobs was a great simplifier, who "handed control to us" as users of Apple devices. But he was also a control freak when it came to designing the same artifacts, supervising fine detail, adding features and forcing his team to work all hours, rather than giving them time for "purposeful daydreaming," as May advocates elsewhere in his book.

"The Artist," the silent, black-and-white film that provides May with the book's coda, was a worthy Oscar winner — but so was 2008's "Slumdog Millionaire," with its cast of thousands and Bollywood-style excess.

May does not avoid these contradictions, but he does not really address them, either. He prefers to list examples of his six laws rather than explore how employers or their staff could reconcile the daily conflict between constraints and freedom, perspiration and inspiration.

In the interests of "owning" his Zen-inspired meme, May subtracts these complexities. Instead he offers tips, such as his invitation to take "long, languid showers" — No. 8 on a list of ways to relax the mind. This point "needs no explanation," May writes, "which is good, because I could find no research on the subject."

For most people at most companies, where the pressure to add customers, revenue and value is intense, it is as difficult to "subtract" as it is for most grown-ups to follow the advice of one of the book's contributors and live out of a suitcase in a near-empty apartment.

It is a pity, given the need to simplify many business processes, that May adds so little to the sum of knowledge about how to do it.

Hill is the management editor of the Financial Times of London, in which this review first appeared.

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.

Facebook Profile May Expose Mental Illness

A person’s Facebook profile may reveal signs of mental illness that might not necessarily emerge in a session with a psychiatrist, a new study suggests.

“The beauty of social media activity as a tool in psychological diagnosis is that it removes some of the problems associated with patients’ self-reporting,” said study researcher Elizabeth Martin, a psychology doctoral student at the University of Missouri. “For example, questionnaires often depend on a person’s memory, which may or may not be accurate.”

Martin’s team recruited more than 200 college students and had them fill out questionnaires to evaluate their levels of extroversion, paranoia, enjoyment of social interactions, and endorsement of strange beliefs. (For example, they were asked whether they agreed with the statement, “Some people can make me aware of them just by thinking about me.”)

The students also were asked to log onto Facebook. They were told they would have the option to black-out parts of their profile before some of it was printed out for the researchers to examine.

“By asking patients to share their Facebook activity, we were able to see how they expressed themselves naturally,” Martin explained in a statement. “Even the parts of their Facebook activities that they chose to conceal exposed information about their psychological state.”

Participants who showed higher levels of social anhedonia — a condition characterized by lack of pleasure from social interactions — typically had fewer Facebook friends, shared fewer photos, and communicated less frequently on the site, the researchers found.

Meanwhile, those who hid more of their Facebook activity before presenting their profiles to researchers were more likely to hold odd beliefs and show signs of perceptual aberrations, which are irregular experiences of one’s senses. They also exhibited higher levels of paranoia.

“However, it should be noted that participants higher on paranoia did not differ from participants lower in paranoia in terms of the amount of personal information shared,” the researchers wrote in their study detailed Dec. 30, 2012, in the journal Psychiatry Research. That finding suggests this group might be more comfortable sharing information in an online setting than in the face-to-face interactions with the experimenter.

The researchers said information culled from social networking sites potentially could be used to inform diagnostic materials or intervention strategies for people with mental health issues.

Disney says JJ Abrams to direct next 'Star Wars'

LOS ANGELES (AP) — It's official. The force is with J.J. Abrams.

The Walt Disney Co. issued a statement Friday night confirming reports that had been circulating for two days that Abrams, Emmy-award-winning creator of TV's "Lost" and director of 2009's "Star Trek" movie, has been pegged to direct the seventh installment of the "Star Wars" franchise.

"J.J. is the perfect director to helm this," said Kathleen Kennedy, the movie's producer and president of Lucasfilm, which was acquired by Disney last month for $4.06 billion.

"Beyond having such great instincts as a filmmaker, he has an intuitive understanding of this franchise. He understands the essence of the Star Wars experience," Kennedy said in the statement.

The movie will have a script from "Toy Story 3" writer Michael Arndt and a 2015 release.

Lawrence Kasdan, who wrote "The Empire Strikes Back" and "Return of the Jedi" in the original trilogy, will work as a consultant on the new project.

Abrams has already headed the reboot of another storied space franchise, "Star Trek," for rival studio Paramount Pictures. The next installment in that series, "Star Trek: Into Darkness," is set to hit theaters May 17.

But he has long been known as a "Star Wars" devotee. Abrams spoke about the plot of the original "Star Wars" in the lecture series "TED Talks" in March 2007, and reportedly became enamored of "Lost" co-creator Damon Lindelof partly because Lindelof was wearing a "Star Wars" T-shirt when they first met.

In 2009, Abrams told the Los Angeles Times: "As a kid, 'Star Wars' was much more my thing than 'Star Trek' was."

In Friday night's statement he called it an "absolute honor" to get the job.

"I may be even more grateful to George Lucas now than I was as a kid," Abrams said.

Lucas himself said in the statement that "I've consistently been impressed with J.J. as a filmmaker and storyteller. He's an ideal choice to direct the new Star Wars film and the legacy couldn't be in better hands."

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

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.

Nokia CEO closes the door on a potential Android smartphone

Nokia (NOK) CEO Stephen Elop on Thursday shot down rumors that his company might be interested in developing Android-based smartphones. During Nokia’s fourth-quarter earnings call, the executive reiterated his support for the company’s Asha phones and Microsoft’s (MSFT) Windows Phone platform, while shutting the door on earlier Android rumors.

[More from BGR: Unlocking your smartphone will be illegal starting next week]

“We are clearly innovating with Microsoft around Windows Phone, and are focused on taking that to lower and lower price points,” he said, according to TechCrunch. “You will see that over time [we will] compete with Android. But at the same time we’ve said consistently — and we’re just beginning to see it in the Asha full-touch products — that we will continue to innovate around our Asha smartphone line in order to compete with the very lowest levels of Android.”

[More from BGR: Why the iOS-Android feud is so intense: It’s about core philosophy more than products]

The executive also took shots at Google (GOOG) and the openness of its Android operating system, or lack thereof.

“The situation that Android is facing, where the amount of fragmentation that you’re seeing is increasing as people take it in different directions, is of course offset by Google’s efforts to turn an open ecosystem into something that’s quite a bit more closed as you’ve seen quite recently,” Elop said.

Elop concluded by saying that Nokia is “not in a situation where we are considering something other than Windows Phone combined with what we’re doing with Asha.”

Damon 'hijacks' Kimmel's ABC show

NEW YORK (AP) — Matt Damon had his revenge.

The butt of a long-running joke on ABC's "Jimmy Kimmel Live," the actor opened Thursday night's show as a kidnapper who tied Kimmel to a chair with duct tape and gagged him with his own tie.

"There's a new host in town and his initials are M.D.," Damon said. "That's right, the doctor is in."

For years, Kimmel has joked at the end of his show that he ran out of time and was unable to bring Damon on as a guest. Kimmel was the silent one Thursday, watching from the back of the stage as Damon did his job.

Damon tormented Kimmel by bringing on a succession of big-name guests. Robin Williams stopped by to finish the monologue. Ben Affleck had a walk-on role. Sheryl Crow was the bandleader and performed her new single. Nicole Kidman, Gary Oldman, Amy Adams, Reese Witherspoon and Demi Moore all crowded the talk show's couch.

"I've been waiting for this moment for a long, long time," Damon said. "This is like when I lost my virginity, except this is going to last way longer than one second."

Damon's guest hosting turn came at a key time for Kimmel. ABC earlier this month moved the show to 11:35 p.m. ET and PT after a decade of airing it a half hour later, putting him in direct competition with Jay Leno and David Letterman.

Thursday's special program aimed for the same water-cooler status as a memorably lewd short film Damon made for the show a few years ago with Kimmel's then-girlfriend, Sarah Silverman. It went viral and remains probably the best-known skit in the show's history.

To twist the knife even further, Damon brought Silverman on as his final guest Thursday night, with Kimmel looking on forlornly as she likened their five-year relationship to an unfortunate trip to a hot dog vendor.

"Is there anything you'd like to say to Jimmy?" Damon asked.

"No, I'm good," Silverman replied.

Then came the sweetest revenge of all, with Damon promising to ungag Kimmel in the show's final minutes.

"Wait," he said. "I'm sorry. We're out of time."

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 DSM 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, David 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 DSM-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 DSM 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 Judy 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 DSM 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.
