Diner’s Journal Blog: PepsiCo Will Halt Use of Additive in Gatorade

PepsiCo announced on Friday that it would no longer use an ingredient in Gatorade after consumers complained.

The ingredient, brominated vegetable oil, which was used in citrus versions of the sports drink to prevent the flavorings from separating, was the object of a petition started on Change.org by Sarah Kavanagh, a 15-year-old from Hattiesburg, Miss., who became concerned about the ingredient after reading about it online. Studies have suggested there are possible side effects, including neurological disorders and altered thyroid hormones.

The petition attracted more than 200,000 signatures, and this week, Ms. Kavanagh was in New York City to tape a segment for “The Dr. Oz Show.” She visited The New York Times on Wednesday and while there said, “I just don’t understand why they can’t use something else instead of B.V.O.”

“I was in algebra class and one of my friends kicked me and said, ‘Have you seen this on Twitter?’ ” Ms. Kavanagh said in a phone interview on Friday evening. “I asked the teacher if I could slip out to the bathroom, and I called my mom and said, ‘Mom, we won.’ ”

Molly Carter, a spokeswoman for Gatorade, said the company had been testing alternatives to the chemical for roughly a year “due to customer feedback.” She said Gatorade initially was not going to make an announcement, “since we don’t find a health and safety risk with B.V.O.”

Because of the petition, though, Ms. Carter said the company had changed its mind, and an unidentified executive there gave Beverage Digest, a trade publication, the news for its Jan. 25 issue.

Previously, a spokesman for PepsiCo had said in an e-mail, “We appreciate Sarah as a fan of Gatorade, and her concern has been heard.”

Brominated vegetable oil will be replaced by sucrose acetate isobutyrate, an emulsifier that is “generally recognized as safe” as a food additive by the Food and Drug Administration. The new ingredient will be added to orange, citrus cooler and lemonade Gatorade, as well Gatorade X-Factor orange, Gatorade Xtremo citrus cooler and a powdered form of the drink called “glacier freeze.”

Ms. Carter said consumers would start seeing the new ingredient over the next few months as existing supplies of Gatorade sell out and are replaced.

Health advocates applauded the company’s move. “Kudos to PepsiCo for doing the responsible thing on its own and not waiting for the F.D.A. to force it to,” said Michael Jacobson, executive director of the Center for Science in the Public Interest.

Mr. Jacobson has championed the removal of brominated vegetable oil from foods and beverages for the last several decades, but the F.D.A. has left it in a sort of limbo, citing budgetary constraints that it says keep it from going through the process needed to formally ban the chemical or declare it safe once and for all.

Brominated vegetable oil is banned as a food ingredient in Japan and the European Union. About 10 percent of drinks sold in the United States contain it, including Mountain Dew, which is also made by PepsiCo; some flavors of Powerade and Fresca from Coca-Cola; and Squirt and Sunkist Peach Soda, made by the Dr Pepper Snapple Group.

PepsiCo said it had no plans to remove the ingredient from Mountain Dew and Diet Mountain Dew, both of which generate more than $1 billion in annual sales.

Heather White, executive director at the Environmental Working Group, said of PepsiCo’s decision, “We can only hope that other companies will follow suit.” She added, “We need to overhaul how F.D.A. keeps up with the latest science on food additives to better protect public health.”

Ms. Kavanagh agreed. “I’ve been thinking about ways to take this to the next level, and I’m thinking about taking it to the F.D.A. and asking them why they aren’t doing something about it,” she said. “I’m not sure yet, but I think that’s where I’d like to go with this.”

Gadgetwise Blog: Is January the Time to Buy Electronics?

At the International Consumer Electronics Show in Las Vegas in early January, manufacturers tantalized consumers with new electronics soon to hit the shelves. But what does that do to the prices of current models that are being replaced? Is this a golden buying opportunity?

Yes and no. Yes for TVs, no for laptops. I’ll explain.

Decide.com, which tracks the price of electronics, studied what happened to the cost of TVs and laptops in past years after C.E.S.

What it found is that TV prices dip to near yearly lows after the show, matching holiday prices. With the average price of the top 250 TVs at $1,057, the post-show average is projected to drop an average of $211, to $846, based on data from previous  years. That is a 20 percent savings.

Laptops don’t drop so steeply. After the show, the 100 most popular laptops have historically been discounted 8 percent. This year that would mean the top 100 laptops, which average $780 in price, would be reduced $62, to $718.

Laptop price are lowest in late June through early July, right before the back to school sales, and during the last two weeks of September, after those sales, according to Decide.com’s data. At those times the discounts are typically 10 percent.

Of course, averages can be deceiving. Prices are volatile all year around, so a particular TV or computer you want could be discounted far more at any time.

There are a number of browser add-ons and apps that let you track prices of individual products, or you can use Decide.com – but it will cost you. Membership is $5 a month or $30 a year for full access.

IHT Rendezvous: Mining the Deep Sea and Outer Space for a Mineral Bonanza

LONDON — Whatever happened to manganese nodules?

As newly announced plans to mine the mineral wealth of asteroids generate a mixture of excitement and skepticism, it is worth recalling the fate of an earlier craze to exploit a potential metals bonanza somewhat closer to home.

From the early 1970s, the prospect of hauling up a boundless harvest of metal rich nodules from the deepest ocean beds was touted as the answer to the world’s increasing hunger for diminishing resources.

The potato-size rocks that carpet the deep seabed — commonly known as manganese nodules — also contain a mix of other elements, including copper, cobalt and nickel.

Governments and private companies joined the treasure hunt as explorations were launched to determine whether projects to vacuum the nodules from miles below the ocean’s surface were commercially viable.

Lockheed Martin led a consortium of companies in an effort to develop a commercial mining operation, collecting thousands of nodules from an area of the Pacific Ocean between Hawaii and Mexico as part of an effort that would today cost more than $500 million.

Howard Hughes, the reclusive American tycoon, fueled the frenzy with the launch of the Glomar Explorer, a 618-foot ship he said was built to mine the manganese nodules. (It was, in fact, cover for a secret C.I.A. project to raise a sunken Soviet submarine.)

The potential “gold rush” was a factor that led to the United Nations Convention on the Law of the Sea that aimed to ensure that the seabed’s wealth outside territorial limits would be shared between developed and developing states.

However, a collapse in the international nickel price between the mid-1970s and mid-1980s shattered the prospects of instant wealth from the billions of tons of ore that lay just beyond the limits of technology available at the time.

The lure of the manganese nodule faded from public consciousness. As an article on the University of Texas’s Science and the Sea website stated in 2009: “A fortune is sitting at the bottom of the world’s oceans. And for the foreseeable future, at least, it’s likely to stay there.”

Interest has been revived, however, by the increasing demand for so-called rare earth metals that are used in many modern high-tech products such as fiber optics, memory chips and liquid-crystal screens.

Studies by Lockheed Martin and others have determined that seabed nodules could provide an alternative source of such metals in a market presently dominated by China.

A Chinese embargo on rare earth metal shipments in 2010 was described by Hillary Rodham Clinton, the U.S. secretary of state, as a “wake-up call” for the world to find new resources.

Interest in manganese nodule exploitation may have subsided since the 1970s but it never quite disappeared.

In the latest initiative this month, G-TEC Sea Mineral Resources, a private Belgium company signed a 15-year contract with the International Seabed Authority to prospect the central Pacific Ocean. The contract was backed by the Belgian government.

The Jamaica-based global body, which organizes and controls exploration of the seabed beyond national territorial limits, has granted a dozen such contracts since it established its Nodule Regulations in 2000.

Three months before, it signed a similar contract with Russia for prospecting and exploration in the Atlantic Ocean.

So, as nodule fever appears to be making a comeback, how about outer space?

Deep Space Industries, a California-based company has just announced its plans to inspect small asteroids that pass by Earth as potential mining targets.

That followed the announcement of plans by another company, Planetary Resources, to send an unmanned robotic mining mission to the asteroid belt, as my colleague Kirk Johnson reported from Washington State last month.

The prospect of mining asteroids was a sci-fi dream of the 1970s, just around the time of the manganese nodule craze.

Its revival has excited space fans but others are skeptical about the projects.

In a down-to-earth column in The Economist entitled “Fool’s Platinum?”, the business magazine suggested the economic case for asteroid mining was far from obvious.

“A doubling of supply from space might, for instance, exert such downward pressure on the price of platinum on Earth as to undermine the whole business case for the venture,” it wrote.

DealBook: Compuware Rejects Elliott's $2.3 Billion Bid

11:46 a.m. | Updated

Compuware said on Friday that its board had rejected a $2.3 billion takeover bid by Elliott Management, arguing that the hedge fund’s offer was too low.

Instead, the business software maker said that it was focused on its own corporate turnaround blueprint, including a three-year plan to cut costs and an effort to spin off its Covisint business communication products arm. It also unveiled plans to pay a 50-cent quarterly dividend, beginning next quarter.

Compuware said that Elliott’s offer of $11 a share, made last month, would not deliver enough value to shareholders, compared to the improvements that its self-help plan would yield.

“We believe that selling the company at $11.00 per share does not take into account our progress returning the business to profitable growth and our future prospects,” Bob Paul, the company’s chief executive, said in a statement.

The decision by Compuware sets up a potential clash with Elliott, which has managed to score some big wins in its battles with technology companies. It bid for Novell, leading the software maker to sell itself to Attachmate for $2.2 billion.

People close to Elliott have argued that the hedge fund was fully prepared to pay the $2.3 billion it had offered for Compuware. But the hedge fund also believed that private equity firms would also express interest.

Though shares in Compuware began rising after Elliott disclosed an 8 percent stake in the company in November, they have remained largely below the $11-a-share offer, implying investor skepticism about a deal being done. The stock closed on Thursday at $10.76.

Jesse Cohn, the Elliott portfolio manager overseeing the hedge fund’s bid, said in a statement: ““This is a good outcome. Compuware has granted our request for access to diligence to confirm an offer for the company. We will immediately reach out to negotiate an appropriate N.D.A. and look forward to moving quickly to engage in diligence with the help of our legal and financial advisors. We remain very interested in the company.”

Well: Ask Well: Squats for Aging Knees

You are already doing many things right, in terms of taking care of your aging knees. In particular, it sounds as if you are keeping your weight under control. Carrying extra pounds undoubtedly strains knees and contributes to pain and eventually arthritis.

You mention weight training, too, which is also valuable. Sturdy leg muscles, particularly those at the front and back of the thighs, stabilize the knee, says Joseph Hart, an assistant professor of kinesiology and certified athletic trainer at the University of Virginia, who often works with patients with knee pain.

An easy exercise to target those muscles is the squat. Although many of us have heard that squats harm knees, the exercise is actually “quite good for the knees, if you do the squats correctly,” Dr. Hart says. Simply stand with your legs shoulder-width apart and bend your legs until your thighs are almost, but not completely, parallel to the ground. Keep your upper body straight. Don’t bend forward, he says, since that movement can strain the knees. Try to complete 20 squats, using no weight at first. When that becomes easy, Dr. Hart suggests, hold a barbell with weights attached. Or simply clutch a full milk carton, which is my cheapskate’s squats routine.

Straight leg lifts are also useful for knee health. Sit on the floor with your back straight and one leg extended and the other bent toward your chest. In this position, lift the straight leg slightly off the ground and hold for 10 seconds. Repeat 10 to 20 times and then switch legs.

You can also find other exercises that target the knees in this video, “Increasing Knee Stability.”

Of course, before starting any exercise program, consult a physician, especially, Dr. Hart says, if your knees often ache, feel stiff or emit a strange, clicking noise, which could be symptoms of arthritis.

IHT Rendezvous: Gallery Stroll: Istanbul

ISTANBUL—Unpredictable weather means winter isn’t the most popular season for visiting Istanbul, but it is a great time for gallery-hopping: Many of the best museums and art spaces in the Beyoglu district have just opened compelling new exhibitions.

At Arter, the curator Emre Baykal has gathered mostly new works by Turkish artists to create the second installment of “Envy, Enmity, Embarrassment.” Here, the artist known as Canan presents the installation, “I beg you please do not speak to me of love,” a room plastered with erotic movie posters from the heyday of the Yesilcam porn industry of the 1970s. In a transparent case in one corner of the room is a seemingly innocent white bathrobe. Embroidered on its back is a suicide note.

Other interesting works include “Twin Goddess: The Sketch of an Encounter,” an embroidered collage by Nilbar Gures using ancient symbols from Anatolian archaeology, and “The Island” by Hera Buyuktasciyan, a look at taboos.

The most powerful piece in this show is Hale Tenger’s “I Know People Like This III.” Visitors who enter the gallery from Istiklal Caddesi walk through this chronological maze of x-ray prints, a sort of light-box labyrinth, that lays out traumatic images from Turkish political history, including public protests, the killing of journalists and scenes of violence that followed the 1980 military coup.

On the parallel street, Mesrutiyet Caddesi, the Pera Museum has just opened a double-barreled program. A retrospective of the works of the Hungarian-American photographer Nickolas Muray covers the dashing man-about-town’s early black-and-white art nudes as well as his color-saturated portraits of beauties like Marilyn Monroe, Elizabeth Taylor and a woman he adored, Frida Kahlo. On another floor, “Between Desert and Sea” presents a selection of 52 works from the Jordan National Gallery of Fine Arts, pieces that speak to topical issues like religion, the rights of women, and the impact of the Arab Spring revolutions.

At the Salt Galata, a 10-minute stroll away on Bankalar Caddesi, “1 + 8″ is an installation of large-screen videos by Cynthia Madansky and Angelika Brudniak, who traveled to the borders between Turkey and its eight neighbors: Greece, Bulgaria, Georgia, Armenia, Nakchivan, Iran, Iraq and Syria to tape local residents talking about their daily lives and hopes. In the case of Iran, just a black screen is shown: The artists were refused permission to film in Iran, but they managed to record audio of Iranians who had crossed into Turkey for personal or business reasons. None felt safe having their faces shown.

DealBook: Choice for S.E.C. Is Ex-Prosecutor, in Signal to Wall St.

President Obama is tapping Mary Jo White, a former United States attorney turned white-collar defense lawyer, to be the next chairwoman of the Securities and Exchange Commission, according to the White House.

Mr. Obama is set to announce the nomination at the White House on Thursday afternoon at 2:30. As part of the event, the White House will also renominate Richard Cordray to lead the Consumer Financial Protection Bureau, a role he has held for the last year under a recess appointment.

In its choice of Ms. White and Mr. Cordray, the White House is sending a signal about the importance of holding Wall Street accountable for wrongdoing. Both are former prosecutors.

Regulatory chiefs are often market experts or academics. But Ms. White spent nearly a decade as United States attorney in New York, the first woman named to this post. Among her prominent cases, she oversaw the prosecution of the mafia boss John Gotti as well as the people responsible for the 1993 World Trade Center bombing. She is now working the other side, defending Wall Street firms and executives as a partner at Debevoise & Plimpton.

As the attorney general of Ohio, Mr. Cordray made a name for himself suing Wall Street companies in the wake of the financial crisis. He undertook a series of prominent lawsuits against big names in the finance world, including Bank of America and the American International Group.

The White House expects Ms. White and Mr. Cordray to draw on their prosecutorial backgrounds while carrying out a broad regulatory agenda under the Dodd-Frank Act. Congress enacted the law, which mandates a regulatory overhaul, in response to the 2008 financial crisis.

“The president will name two individuals to serve in top enforcement roles in his administration to help ensure we are effectively implementing these reforms so that Wall Street is held accountable and middle-class Americans never again are harmed by the abuses of a few,” a White House official said.

Ms. White will succeed Elisse B. Walter, a longtime S.E.C. official, who took over as chairwoman after Mary L. Schapiro stepped down as the agency’s leader in December. Mr. Cordray joined the consumer bureau in 2011 as its enforcement director.

The nominations could face a mixed reception in Congress. The Senate already declined to confirm Mr. Cordray, with Republicans vowing to block any candidate for the consumer bureau, a new agency created to rein in the financial industry’s excesses. It is unclear whether the White House and Mr. Cordray will face another standoff the second time around.

Ms. White, 65, is expected to receive broad support. But she could face questions about her command of arcane financial minutiae. She was a director of the Nasdaq stock market, but has otherwise built her career on the law-and-order side of the securities industry.

People close to the S.E.C. note, however, that her husband, John W. White, is a veteran of the agency. From 2006 through 2008, he was head of the S.E.C.’s division of corporation finance, which oversees public companies’ disclosures and reporting.

Some Democrats also might question her path through the revolving door, in and out of government. While seen as a strong enforcer as a United States attorney, she went on in private practice to defend some of Wall Street’s biggest names, including Kenneth D. Lewis, a former head of Bank of America. She also represented JPMorgan Chase and the board of Morgan Stanley. Last year, the N.F.L. hired her to investigate allegations that the New Orleans Saints carried out a bounty system for hurting opponents.

Consumer advocates generally praised her appointment on Thursday. “Mary Jo White was a tough, smart, no-nonsense, broadly experienced and highly accomplished prosecutor,” said Dennis Kelleher, head of Better Markets, the nonprofit advocacy group. “She knew who the bad guys were, went after them and put them in prison when they broke the law.”

The appointment comes after the departure of Ms. Schapiro, who announced she would step down from the S.E.C. in late 2012. In a four-year tenure, she overhauled the agency after it was blamed for missing the warning signs of the crisis.

Since her exit, Washington and Wall Street have been abuzz with speculation about the next S.E.C. chief. President Obama quickly named Ms. Walter, then a Democratic commissioner at the agency, but her appointment was seen as a short-term solution.

In the wake of Ms. Schapiro’s exit, several other contenders surfaced, including Sallie L. Krawcheck, a longtime Wall Street executive. Richard G. Ketchum, chairman and chief executive of the Financial Industry Regulatory Authority, Wall Street’s internal policing organization, was also briefly mentioned as a long-shot contender.

Well: Can You Read the Face of Victory?

Picture a tennis player in the moment he scores a critical point and wins a tournament. Now picture his opponent in the instant he loses the point that narrowly cost him the title. Can you tell one facial expression from the other, the look of defeat from the face of victory?

Try your hand at the images below, of professional tennis players at competitive tournaments. All were included in a new study that suggests that the more intense an emotion, the harder it is to distinguish it in a facial expression.

---

The researchers found that when overwhelming feelings set in, the subtle cues that convey emotion are lost, and facial expressions tend to blur. The face of joy and celebration often appears no different from the look of grief and devastation. Winning looks like losing. Pain resembles pleasure.

But that is not the case when it comes to body language. In fact, the new study found, people are better able to identify extreme emotions by reading body language than by looking solely at facial expressions. But even though we pick up on cues from the neck down to interpret emotion, we instinctively assume that it is the face that tells us everything, said Hillel Aviezer, a psychologist who carried out the new research with colleagues at Princeton University.

“When emotions run high, the face becomes more malleable: it’s not clear if there’s positivity or negativity going on there,” he said. “People have this illusion that they’re reading all this information in the face. We found that the face is ambiguous in these situations and the body is critical.”

Dr. Aviezer and his colleagues, who published their work in the journal Science, carried out four experiments in which subjects were asked to identify emotions by looking at photographs of people in various situations. In some cases, the subjects were shown facial expressions alone. In others, they looked at body language, either alone or in combination with faces. The researchers chose photographs taken in moments when emotions were running high – as professional tennis players celebrated or agonized, as loved ones grieved at funerals, as needles punctured skin during painful body piercings.

According to classic behavioral theories, facial expressions are universal indicators of mood and emotion. So the more intense a particular emotion, the easier it should be to identify in the face. But the study showed the exact opposite. As emotions peaked in intensity, expressions became distorted, similar to the way cranking up the volume on a stereo makes the music unrecognizable.

“When emotions are extremely high, it’s as if the speakers are blaring and the signal is degraded,” said Dr. Aviezer, who is now at Hebrew University in Jerusalem. “When the volume is that high, it’s hard to tell what song is playing.”

In one experiment, three groups of 15 people were shown photographs of professional tennis players winning and losing points in critical matches. When the subjects were shown the players’ expressions alone — separated from their bodies — they correctly identified their emotion only half of the time, which was no better than chance. When they looked at images of just the body with the face removed — or the body with the face intact — they were far more accurate at identifying emotions. Yet when asked, 80 percent said they were relying on the facial expressions alone. Twenty percent said they were going by body and facial cues together, and not a single one said they were looking only for gestures from the neck down.

Then, the researchers scrambled the photos, mixing faces and bodies together. The upset faces of players were randomly spliced onto the bodies of celebrating players, and vice versa.

When asked to judge the emotions, the subjects answered according to the body language. The facial expression did not seem to matter. If a losing face was spliced onto a celebrating body, the subjects tended to guess victory and jubilation. If they were looking at the face of an exuberant player placed on the body of an anguished player, the subjects guessed defeat and disappointment.

Although they were not aware of it, the subjects were clearly looking at body language, Dr. Aviezer said. Clenched fists, for example, suggested victory and celebration, while open or outstretched hands indicated a player’s disappointment.

In another experiment, the researchers looked at four other emotional “peaks.” For pain, they used the faces of men and women undergoing piercings. Grief was captured in images of mourners at a funeral. For joy, they used images of people on the reality television show “Extreme Makeover: Home Edition,” capturing their impassioned faces at the very moment they were shown their beautiful, brand new homes. And for pleasure, they went with a rather risqué option: images from an erotic Web site that showed faces at the height of orgasm.

Once again, the subjects could not correctly guess the emotions by looking at facial expressions alone. In fact, they were more likely to interpret “positive” faces as being “negative” more than the actual negative ones. When faces showing pleasure were spliced onto the body of someone in pain, for example, the subjects relied on body language and were often unaware that the facial expression was conveying the opposite emotion.

“There’s this point on ‘Extreme Makeover’ where people see their new house for the first time and the camera is on their face, so we have these wonderful photos of their expressions,” Dr. Aviezer said. “At that moment, they look like the most miserable people in the world. For a few seconds, it’s as if they are seeing their house burn down. They don’t look like you would expect.”

The researchers noted that they were not suggesting that facial expressions never indicate specific feelings – only that when the emotion is intense and at its peak, for those first few seconds, the expression is ambiguous. Dr. Aviezer said the facial musculature simply might not be suited for accurately conveying extremely intense feelings – in part because in the real world, so much of that is conveyed through situational context.

And this may not be limited to facial cues.

“Consider intense vocal expressions of grief versus joy or pleasure versus pain,” the researchers wrote in their paper. For example, imagine sitting in a coffee shop and hearing someone behind you shriek. Is it immediately obvious whether the emotion is a positive or negative one?

“When people are experiencing a very high level of excitation,” Dr. Aviezer said, “then we see this overlap in expressions.”
