Ask Well: Coaxing Parents to Take Better Care of Themselves

Dear Reader,

Your dilemma of wanting to get your parents to change their ways to eat better and exercise reminds me of an old joke:

How many psychologists does it take to change a light bulb? Answer: Only one, but the light bulb has to really want to change.

Sounds like your parents may be about as motivated as the light bulb right now. Still, there are things you can do to encourage them to move in a healthier direction. But the first step should not be to hand them a book. Unless you lay some prior groundwork, that gesture may seem almost as patronizing as an impatient tone of voice – and probably as likely to backfire.

Instead, start a conversation in a caring, nonjudgmental way. Ask, don’t tell. “Say, ‘You know, I might not know what I am talking about, but I am really concerned about you,” suggested Kevin Leman, a psychologist in Tucson, Ariz., and author of 42 books on changing behavior in families and relationships. Ask simply if there is anything you can do to help.

Leading by example is also more effective than lecturing. “The son can role-model health by inviting his parents to dinner and serving healthful items that he is fairly certain they will find acceptable, or ask them if they are interested in going out dancing with him and his wife,” suggested Ann Constance, director of the Upper Peninsula Diabetes Outreach Network in Michigan.

Pleasure is a better motivator for change than pain or threats. Use the grandchildren as bait. Ask if they want to take the grandchildren to the zoo or a park that would require a good bit of walking around for everyone. Or the grandchildren could ask them to come along on one of those 2K fund-raiser-walks that many schools hold. After all, a day with the grandchildren is always a pleasure in itself. (O.K., usually a pleasure.)

Tempted to give them the gift of a health club membership? “Save your money,” Dr. Leman said. Try a more indirect (and cheaper) approach. Create a mixed-tape of up-tempo music from their era. (“Songs they listened to from the ages of 12-to-17, which is what we all listen to for the rest of our lives,” said Dr. Leman) They will enjoy it any time — maybe even while walking.

If you really want someone you love to make a change, the key is to ask them to do something small and easy first because that increases the chances they will do something larger later. Psychologists call that “the foot in the door technique,” said Adam Davey, associate professor of public health at Temple University in Philadelphia, referring to a classic 1966 experiment called “Compliance Without Pressure.” In the study, which has been duplicated by others in many forms, researchers asked people to sign a petition or place a small card in a window in their home or car about keeping California beautiful or supporting safe driving. About two weeks later, the same people were asked to put a huge sign that practically covered their entire front lawn advocating the same cause.

“A surprisingly large number of those who agreed to the small sign agreed to the billboard,” because agreeing to the first small task built a bond between asker and askee “that increases the likelihood of complying with a subsequent larger request,” Dr. Davey explained.

Any plan for behavioral change is most likely to succeed if it is very specific, measurable and achievable, according to Ms.Constance.

And the new behavior should also be integrated into daily life — and repeated until it becomes a habit. For example, if you want to walk more, start with a 10-minute walk after dinner on Monday, Wednesday and Friday, Ms. Constance suggested. The next week, bump it up to 12 minutes.

Don’t give up, even if you meet initial resistance — it is never too late for your parents or you or any of us to change. “Taking up an exercise program into one’s 80s and 90s to build strength and flexibility can result in very tangible and enduring benefits in a surprisingly short time,” insisted Dr Davey.

As for instructive reading, Dr. Leman is partial to one of his own books, “Have a New You by Friday,” and Dr. Davey recommends “Biomarkers: The 10 Keys to Prolonging Vitality,” by William Evans. Ms. Constance recommends the Centers for Disease Control and Prevention’s Web site on physical activity and exercise tips for the elderly, as well as the National Institute of Health’s site on the DASH diet.

Bits Blog: Tech Predictions for 2013: It's All About Mobile

If there is one theme that will be the topic of digital business this year, it is mobile.

ComScore, which tracks Web and mobile usage, published a report about what happened in 2012, and what to expect in 2013.

It shows that the effects of a movement toward mobile are everywhere, from shopping to media to search. According to the report, “2013 could spell a very rocky economic transition,” and businesses will have to scramble to stay ahead of consumers’ changing behavior.

Here are a few interesting tidbits from the 48-page report.

The mobile transition is happening astonishingly quickly. Last year, smartphone penetration crossed 50 percent for the first time, led by Android phones. People spend 63 percent of their time online on desktop computers and 37 percent on mobile devices, including smartphones and tablets, according to comScore.

Just as they compete on computers, Facebook and Google are dominant and at each other’s throats on phones.

Google’s map app for the iPhone, which had been the most used mobile app, lost its No. 1 spot to Facebook after Apple kicked Google’s maps off the iPhone in October. Now, Facebook reaches 76 percent of the smartphone market and accounts for 23 percent of total time spent using apps each month. The next five most used apps are Google’s, which account for 10 percent of time on apps.

As mobile continues to take share from desktop, some industries have been particularly affected, and they are seeing significant declines in desktop use of their products as a result. They are newspapers, search engines, maps, weather, comparison shopping, directories and instant messenger services.

The most visited Web sites are not so surprising: Google, Yahoo, Microsoft, Facebook and Amazon. Facebook continues to take up most of our time online.

But there were a few surprises from younger, smaller Web companies. Tumblr was No. 8 on the list of sites, ordered by time spent on them. And several Web sites were breakout hits last year, as measured by growth and visitor numbers: Spotify (music), Dropbox (online storage), Etsy (shopping), BuzzFeed (news), JustFab (shopping), SoundCloud (music) and BusinessInsider (news).

Search, one of the biggest and most reliable Web industries, is at a crossroads, comScore said. Even though the search market continues to be extraordinarily profitable, there is a desire for it to evolve and offer new services to users.

Here is some evidence: Searches on traditional search engines, dominated by Google, declined 3 percent last year, and the number of searches per searcher declined 7 percent. Yet searches on specialty sites, known as vertical search engines, like Amazon.com or Whitepages.com, climbed 8 percent.

Social search, based on what users’ friends like, has put Facebook and Google on a “collision course,” comScore said, particularly in searches for local businesses like restaurants.

In social networking, the visual Web, as comScore calls it, has transformed the landscape. Pinterest, Tumblr and Instagram, all of which emphasize images, each gained more than 10 million visitors last year.

Last year was also pivotal for online video, comScore said, as viewers increasingly seek the ability to watch video when and where they want. Watching TV shows online helped last year break viewing records, especially during the Olympics.

In the United States, 75 million people a day watch online video and stream 40 billion videos a month, and viewing is driven by YouTube.

There has also been a turning point for video ads. They cost more than typical ads, and have always lagged behind viewership. But in 2012, 23 percent of videos were accompanied by an ad, up from 14 percent the year before. More TV ad dollars are coming to online video, comScore concluded.

Though e-commerce spending grew 13 percent last year, it was a disappointing holiday season online, largely because of economic pressures. Purchasing on mobile phones is beginning to make a dent in e-commerce, comScore said, with mobile shopping accounting for 11 percent of e-commerce in the fourth quarter of 2012, up from 3 percent in the period two years earlier.

IHT Rendezvous: Q and A: Nina Hoss, at Home at the Berlinale

BERLIN — The German actress Nina Hoss has been a fixture at the Berlinale in recent years. She won the best actress prize in 2007 for Christian Petzold’s “Yella,” served on the jury in 2011 and starred in one of the most acclaimed titles in last year’s competition, “Barbara,” also directed by Mr. Petzold (with whom she has made five movies in the past dozen years).

This year Ms. Hoss returned to the festival with “Gold,” her first film with Thomas Arslan, the German director often grouped with Mr. Petzold as a founding member of the Berlin School movement. A laconic and methodical neo-western, “Gold” chronicles the arduous expedition of several German fortune seekers into the Klondike hinterlands. Ms. Hoss plays Emily Meyer, a poised and somewhat enigmatic divorcée who may be the most driven member of the group, determined to forge ahead at all costs. It’s a typically restrained yet suggestive performance from an actress who has made an art of holding back.

Ms. Hoss, who will next be seen opposite Philip Seymour Hoffman in Anton Corbijn’s adaptation of John le Carré’s novel “A Most Wanted Man,” spoke about “Gold” and her collaborations with Mr. Arslan and Mr. Petzold in an interview at the Hotel Mandala during the festival.

Here are edited excerpts from the conversation:

Q.

When you take on a period role, as you’ve done with “Gold” and “Barbara,” do you approach it differently?

A.

As a character you always deal with the environment you live in — that helps you understand why they react the way they do. With Emily, for instance, she wears a corset at the beginning, so there’s a restriction right away, but eventually she lets go. These aren’t problems a modern woman would deal with. But they were only allowed to wear skirts in those days, and they even had to take care of the length of the skirt — the Canadian police would actually fine them if they weren’t long enough. Knowing that, even if we don’t talk about it in the movie, helps you to create the character.

Q.

What else did the research involve?

A.

There’s a Canadian writer, Pierre Berton, who wrote books about the Klondike Gold Rush with loads of photographs. But the thing that helped me the most was making a research trip to Dawson City [the destination in “Gold”] three weeks before shooting. I wanted to see where they wanted to go. When you get to this place in the middle of nowhere — really, you drive for six hours and maybe you see 15 cars, no houses, and it’s still wild — you have this feeling of wanting to stay for some weird reason. I understood what they were longing for.

The people who live there are adventurous, they’re open, and they have to work with each other because otherwise they’re never make it through the winter. I could feel it, this simplicity but also the possibility of a new society, which was particularly interesting for a character like Emily. There are not so many books on women during that time but in Dawson City I found some books on local history. There were women who went there looking for adventure and for freedom and to create themselves again. There was no one to tell you that you couldn’t, so women succeeded there and that was a very interesting perspective on those days.

Q.

What about physical preparations?

A.

We had riding lessons here outside of Berlin, and there were lots of preparations with all the props. There was a specialist who taught us how they made fire. We had to practice packing and unpacking the horses, how to saddle them properly. It was practical training more than intellectual discussions.

Q.

Was it a difficult shoot?

A.

It was quite exhausting. Because it’s a low-budget project there are not too many people around to help with the horses, for example. You can imagine, these seven actors in a dense forest, holding their horses for hours, until the camera is ready. They get crazy — the horses, I mean.

Q.

To what extent did you think of “Gold” as a western?

A.

More a road movie. I think it’s not as lawless as a western. It has parts of the genre in it, like revenge and a shootout. But what I found quite interesting is being German in this country, it’s as if they bring the law with them, and there are all these restrictions that they put on themselves. When you see this German group in the forests of Canada, it immediately tells you how far they’ve traveled. What I found interesting was thinking about what makes people follow their dreams, how hope keeps you going and how it can destroy you.

Q.

Did you see similarities between Emily and Barbara? They’re living in very different circumstances but both are extremely focused women, self-sufficient out of necessity.

A.

In that sense, maybe, and also in that they have principles. Emily has strong principles and is very pragmatic, and same with Barbara. They are women with principles and also they don’t want to let go. For me there’s something very positive underneath with both of them. They believe in life and they want to live, with all its ups and downs. They want to die and say, I lived. No one took it away from me.

But Emily doesn’t have to hold back as much. She does in the beginning because it was dangerous for women to be on their own, so she can’t just be too openhearted.

Q.

Since your characters often reveal little about themselves, do you create back stories for them?

A.

To be so restricted in some of these roles, especially in Christian’s films, can be a tough job. That’s why I need to do other types of films and theater — you become an actor to express yourself, and it’s tough to restrain yourself all the time. I love it, of course, because it’s a specific kind of task and I love the characters Christian writes for me. But I need to know everything about her. From the script I can guess that’s probably why she reacts a certain way, maybe because of the past, so I construct something.

With these characters you don’t just react and say what you think. It’s more like, oh, I would like to say this now but I can’t, so I’m saying this instead. There are so many things going on that I need to exactly know what she wanted to say. That has to be precise, otherwise I go crazy. But I don’t force it. I don’t feel like I need to tell the audience what I’m thinking right now. I love that it can be very precise for me, but when you watch it your mind creates your own story for her.

Drug Makers Increasingly Join Fight Against Doping

Now, a growing number of pharmaceutical companies are trying to prevent their drugs from the same fate by joining with antidoping officials to develop tests to detect the illegal use of their drugs among athletes.

Two major drug makers, Roche and GlaxoSmithKline, have begun evaluating every new drug candidate for its potential to be abused by athletes and have agreed to share information about those products with the World Anti-Doping Agency, known as WADA, which polices drug use in international sports. Several other smaller companies have provided proprietary information about specific drugs. A conference in Paris in November dedicated to the topic drew 250 participants.

The development reflects a significant shift from the days when drug makers paid little attention to how their products could be abused by athletes, said David Howman, the director general of the antidoping agency. In the past, drug makers “felt that any publicity in relation to antidoping control would be negative,” he said. “But what they discovered is the opposite happened.”

Instead of shying away from such stories, Roche and Glaxo have promoted their involvement as an example of good corporate citizenship. Last year, Glaxo went so far as to sponsor the testing laboratories for the London Games, the first time in Olympic history that an antidoping laboratory had a named corporate sponsor.

Pauline Williams, who leads the team at Glaxo that runs the antidoping initiative, said the cooperation with WADA grew out of that sponsorship. “What the London 2012 involvement led to was a real pride and willingness, and a positive attitude toward this continued engagement,” she said. Since the start of the program, the company said it has shared information about four of its projects, and development of a test for one drug is under way.

Antidoping officials have long sought information from drug companies. For instance, Amgen, which developed EPO, helped develop a test for Aranesp, another of its drugs that has been used in doping, in advance of the 2002 Salt Lake Olympics. But such arrangements were ad hoc and fairly simple, said Olivier Rabin, the antidoping agency’s science director. “It was almost more by chance when it was happening,” he said.

Relationships between antidoping officials and pharmaceutical companies have sometimes been tense. In 2006, Amgen was criticized for sponsoring the Tour of California at a time when EPO abuse was rampant among cyclists. Although the company said it had sponsored the race to raise awareness about doping, it was later revealed that the organizers had failed to test for EPO, short for erythropoietin, a synthetic hormone that, like Aranesp, stimulates the production of red blood cells.

“They were associated with some things in the past which we felt were probably inappropriate,” Mr. Howman said. “What we had to do was start the conversation from scratch, and say let’s see how we can work together.”

Steven Elliott, the Amgen scientist who invented Aranesp, said the misperceptions went both ways. He said some believed, wrongly, that biotechnology companies were developing drugs that could be misused by athletes as a way to increase sales. “There was this uneasiness about that,” said Mr. Elliott, who recently retired but continues to work as a liaison between biotechnology companies and the antidoping agency. “There had to be this realization that it was a win-win for both sides.”

Antidoping officials began to work more closely with drug makers after 2004, when Dr. Rabin heard that athletes were talking about a new version of EPO, called CERA, that was being developed by Roche, and asked the company for help.

“We were shocked when they first contacted us,” recalled Barbara Leishman, who oversees the antidoping program there. She said company scientists had not realized that athletes were following the drug’s development so closely. “This is not the sort of thing we like to hear about our compounds.”

Roche then worked with the antidoping agency to develop a blood test for the new drug, turning over proprietary compounds, called reagents, that would help officials test for their drug. Because of the complex nature of the drug, which mimics the body’s own hormones, and the development of the test, the project took years.

In 2009, blood samples from six athletes taken during the Beijing Olympics tested positive for CERA. Other drug makers took note of the media attention Roche received for the collaboration, Mr. Howman said. “Once there’s a foot in the water, then you can follow and walk right in,” he said.

Roche broadened its agreement with WADA, expanding the project to screen all of its drugs in development. Glaxo followed suit and around the same time, two major industry groups representing biotechnology and pharmaceutical companies adopted policies encouraging their members to cooperate.

Halting the abuse of new prescription drugs is only part of the antidoping picture. Athletes today are believed to use a variety of methods to gain an advantage, from transfusing their own blood to taking tiny quantities of tried-and-true doping agents. And some performance-enhancing drugs gain life in illicit laboratories, as was the case with “the clear,” the designer steroid developed in the Bay Area Laboratory Co-operative that toppled star athletes like Marion Jones.

Still, pharmaceutical companies have an important role to play given how complex new drugs have become, and how athletes are increasingly using substances that closely mimic the body’s natural processes, officials said.

“Developing detection methods to show that the substance taken in a synthetic form is different than your natural substance is more challenging,” said Matthew Fedoruk, the science director for the United States Anti-Doping Agency.

Many pharmaceutical companies already have the tools to create a doping test for their products because the Food and Drug Administration and other regulatory bodies require them to show how the drug passes through the body. During the development process, the companies design reagents to help identify the drug. Amgen and other companies, like the biotechnology company Affymax — which makes a competing anemia drug called Omontys — have given WADA some of these reagents for use in developing tests.

Still, Dr. Rabin and others said some companies needed persuading and did not return his calls. In those cases, he said, he uses peer pressure, reminding them that other companies are also participating.

“We know the progress of their drugs, and we know that at some point collaboration will naturally come,” he said. “We are a bit stubborn.”

Well: Twins Don't Need C-Sections

Obstetricians increasingly recommend planned Caesarean sections for women having twins, but a new study has found that a C-section for healthy twins usually provides no advantage over vaginal delivery.

Researchers randomly assigned 2,800 mothers carrying healthy twins to either a planned C-section or a planned vaginal delivery. There was no difference in outcome between the two groups. There were serious medical problems, like bone fracture or abnormal levels of consciousness, in 36 babies delivered by C-section and 35 delivered vaginally. Twenty-one babies delivered by C-section died, as did 17 delivered vaginally.

Mothers fared equally well in each group, with serious health problems in 7.3 percent of the C-section mothers and in 8.5 percent of the vaginal delivery group.

The trial was carried out in well-equipped health care settings and by practitioners experienced in multiple births. “These skills should be available to anyone trained in obstetrics,” said the lead author, Dr. Jon Barrett, chief of maternal-fetal medicine at Sunnybrook Health Sciences Center in Toronto. “This indicates the need for the current generation of obstetricians who have these skills to impart them to their students and give women the opportunity for the best choice.”

Results of the study were presented at a medical conference in San Francisco last week.

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?

A First Step on Continent for Google on Use of Content

PARIS — Publishers in France say they have struck an innovative agreement with Google on the use of their content online. Their counterparts elsewhere in Europe, however, say the French gave in too easily to the Internet giant.

The deal was signed this month by President François Hollande of France and Eric E. Schmidt, the executive chairman of Google, who called it a breakthrough in the tense relationship between publishers and Google, and as a possible model for other countries to follow.

Under the deal, Google agreed to set up a fund, worth €60 million, or $80 million, over three years, to help publishers develop their digital units. The two sides also pledged to deepen business ties, using Google’s online tools, in an effort to generate more online revenue for the publishers, who have struggled to counteract dwindling print revenue.

But the French group, representing newspaper and magazine publishers with an online presence, as well as a variety of other news-oriented Web sites, yielded on its most important demand: that Google and other search engines and “aggregators” of news should start paying for links to their content.

Google, which insists that its links provide a service to publishers by directing traffic to their sites, had fiercely resisted any change in the principle of free linking.

The agreement dismayed members of the European Publishers Council, a lobbying group in Brussels, which has been pushing for a fundamental change in the relationship between publishers and Google. The group criticized the French publishers for breaking ranks and striking a separate business agreement that has no statutory standing.

The deal “does not address the continuing problem of unauthorized reuse and monetization of content, and so does not provide the online press with the financial certainty or mechanisms for legal redress which it needs to build sustainable business models and ensure its continued investment in high-quality content,” Angela Mills Wade, executive director of the publishers council, said in a statement.

German publishers were also scornful, with Anja Pasquay, a spokeswoman for the German Newspaper Publishers’ Association, saying: “Obviously the French position isn’t one that we would favor. This is not the solution for Germany.”

Germany has been in the forefront of the push to get Google to share with online news publishers some of the billions of euros that the company earns from the sale of advertising. A proposed law, endorsed by the government of Chancellor Angela Merkel and working its way through the federal legislature, would grant a new form of copyright to digital publishers. If enacted, it could allow publishers to charge search engines or aggregators for displaying even snippets of news articles alongside links to other Web sites.

Mr. Hollande had vowed to introduce similar legislation this winter if Google and the publishers did not come to terms. It appears that Google, which had threatened to stop indexing French Web sites’ content if it had to pay for links, has sidelined the threat of legislation, at least for now; the agreement will be reviewed after three years, Mr. Hollande has said.

Under the deal, Google says it will help the publishers use several of its digital advertising services, including AdSense, AdMob and Ad Exchange, more effectively.
