Mobile Video Calling Spreads as Smartphones and Tablets Improve

PALO ALTO, Calif. — The next competition in technology is your face — anywhere, anytime.

As the cameras and screens of smartphones and tablets improve, and as wireless networks offer higher bandwidth, more companies are getting into the business of enabling mobile video calls.

The details vary from one service to the next, but the experiences are similar: from anywhere in the world with a modern wireless network, a smartphone’s screen fills with the face of a friend or relative. The quality is about the same jerky-but-functional level as most desktop video. Sound is not always perfectly synced with the image, but it is very close. The calls start and end the same way, by pressing a button on the screen.

Mobile video calling has risen so quickly that industry analysts have not yet compiled exact numbers. But along the way, it is creating new business models, new stresses on mobile networks and even new rules of etiquette.

“All the communications — social messages, calls, texts and video — are merging fast,” said Eric Setton, co-founder and chief technology officer of Tango Mobile, whose free video calling service has 80 million active users. An additional 200,000 join daily, Mr. Setton said.

Once an interesting endeavor for a few start-ups like Tango, mobile video has caught the attention of big companies. Apple created FaceTime and made it a selling point for the iPad.

In September, the company made FaceTime available on cellular networks instead of limiting it to Wi-Fi systems, almost certainly in response to increasing consumer demand.

Last week, Yahoo purchased a video chat company called OnTheAir. And in 2011, Microsoft paid $8.5 billion for Skype, a service for both video and audio-only calls. Though most people use Skype on desktop and laptop computers, the software for the service has been downloaded more than 100 million times just by owners of phones running Google’s Android mobile operating system. Microsoft built a service for its Windows 8 mobile phone that lets people receive calls even when Skype is not on.

Google, which has more than 100 million people a month using its Google Plus social networking service, now offers more than 200 apps for its video calling feature. It says it is interested not in making money on the applications, but in learning more about them so it can sell more ads by getting people to use its free video service, called Hangouts. Hangouts can be used for two-person or group calls, or for a video conference with up to 10 people.

“On a high level, Google works better when we know who you are and what your interests are,” said Nikhyl Singhal, director of product management for Google’s real-time communications group. “Video calling is becoming a basic service across different fronts.” While Mr. Singhal is an occasional user, he said, his 4-year-old daughter “is on it every day.”

Don’t expect video calling to improve productivity. Tango uses the same technology that enables video calls to sell games that people can play simultaneously. It sells virtual decorations like balloons to drop around someone’s image during a birthday call (both parties see the festive pixels). Google says some jokey applications on Hangouts, like a feature that can put a mustache over each caller, seem to encourage people to talk longer.

Currently, popular two-way games like Words With Friends on Facebook work by one player making a move and then passing the game over to the other player, not watching moves as they are made. Another promising area is avatars, like cartoon dogs and cats, that mouth speech when a user wants to have a video call but does not want to be seen.

The prospect of having to appear on-screen at any given moment might sound like a nonstarter for people who worry about bad hair days. But in fact, using mobile devices for video calls may be less bother than it seems.

“There may be natural inhibitions to being seen, but when I’m on a mobile device I’m out and about, so I’m more likely to be presentable,” said Michael Gartenberg, a consumer technology analyst at Gartner. “How people use this remains to be seen, but they are starting to expect it.”

Yet a new etiquette for mobile video calls is already emerging. People often text each other first to see if it’s O.K. to appear on camera. Video messages sent in the text box of a phone, like snippets of a party or a child’s first steps, are also useful precursors to video conversations. Mr. Singhal said making avatars for users of Hangout would be “an extraordinarily important area” as well.

The greatest challenge for the business may not be getting more consumers to use the service, but making sure the service works. Most phones have slight variations in things like camera placement and video formatting from one model to the next. “A camera can show you upside down if you load the wrong software on it,” said Mr. Setton of Tango.

As a result, the 80 engineers among Tango’s 110 employees have adjusted their software to work on more than 1,000 types of phones worldwide. The top 20 models have more than a million customers each, but the complexity of building software for a wider range of phones has made it hard for new mobile video companies to enter the field, Mr. Setton said.

Tango’s average video call used to last six minutes, Mr. Setton said, but when the company started adding other applications to go with the videos, like games and designs that float over people, the average call length rose to 12 minutes.

A Breakthrough Against Leukemia Using Altered T-Cells

PHILIPSBURG, Pa. — Emma Whitehead has been bounding around the house lately, practicing somersaults and rugby-style tumbles that make her parents wince.

It is hard to believe, but last spring Emma, then 6, was near death from leukemia. She had relapsed twice after chemotherapy, and doctors had run out of options.

Desperate to save her, her parents sought an experimental treatment at the Children’s Hospital of Philadelphia, one that had never before been tried in a child, or in anyone with the type of leukemia Emma had. The experiment, in April, used a disabled form of the virus that causes AIDS to reprogram Emma’s immune system genetically to kill cancer cells.

The treatment very nearly killed her. But she emerged from it cancer-free, and about seven months later is still in complete remission. She is the first child and one of the first humans ever in whom new techniques have achieved a long-sought goal — giving a patient’s own immune system the lasting ability to fight cancer.

Emma had been ill with acute lymphoblastic leukemia since 2010, when she was 5, said her parents, Kari and Tom. She is their only child.

She is among just a dozen patients with advanced leukemia to have received the experimental treatment, which was developed at the University of Pennsylvania. Similar approaches are also being tried at other centers, including the National Cancer Institute and Memorial Sloan-Kettering Cancer Center in New York.

“Our goal is to have a cure, but we can’t say that word,” said Dr. Carl June, who leads the research team at the University of Pennsylvania. He hopes the new treatment will eventually replace bone-marrow transplantation, an even more arduous, risky and expensive procedure that is now the last hope when other treatments fail in leukemia and related diseases.

Three adults with chronic leukemia treated at the University of Pennsylvania have also had complete remissions, with no signs of disease; two of them have been well for more than two years, said Dr. David Porter. Four adults improved but did not have full remissions, and one was treated too recently to evaluate. A child improved and then relapsed. In two adults, the treatment did not work at all. The Pennsylvania researchers were presenting their results on Sunday and Monday in Atlanta at a meeting of the American Society of Hematology.

Despite the mixed results, cancer experts not involved with the research say it has tremendous promise, because even in this early phase of testing it has worked in seemingly hopeless cases. “I think this is a major breakthrough,” said Dr. Ivan Borrello, a cancer expert and associate professor of medicine at the Johns Hopkins University School of Medicine.

Dr. John Wagner, the director of pediatric blood and marrow transplantation at the University of Minnesota, called the Pennsylvania results “phenomenal” and said they were “what we’ve all been working and hoping for but not seeing to this extent.”

A major drug company, Novartis, is betting on the Pennsylvania team and has committed $20 million to building a research center on the university’s campus to bring the treatment to market.

Hervé Hoppenot, the president of Novartis Oncology, called the research “fantastic” and said it had the potential — if the early results held up — to revolutionize the treatment of leukemia and related blood cancers. Researchers say the same approach, reprogramming the patient’s immune system, may also eventually be used against tumors like breast and prostate cancer.

To perform the treatment, doctors remove millions of the patient’s T-cells — a type of white blood cell — and insert new genes that enable the T-cells to kill cancer cells. The technique employs a disabled form of H.I.V. because it is very good at carrying genetic material into T-cells. The new genes program the T-cells to attack B-cells, a normal part of the immune system that turn malignant in leukemia.

The altered T-cells — called chimeric antigen receptor cells — are then dripped back into the patient’s veins, and if all goes well they multiply and start destroying the cancer.

The T-cells home in on a protein called CD-19 that is found on the surface of most B-cells, whether they are healthy or malignant.

A sign that the treatment is working is that the patient becomes terribly ill, with raging fevers and chills — a reaction that oncologists call “shake and bake,” Dr. June said. Its medical name is cytokine-release syndrome, or cytokine storm, referring to the natural chemicals that pour out of cells in the immune system as they are being activated, causing fevers and other symptoms. The storm can also flood the lungs and cause perilous drops in blood pressure — effects that nearly killed Emma.

Steroids sometimes ease the reaction, but they did not help Emma. Her temperature hit 105. She wound up on a ventilator, unconscious and swollen almost beyond recognition, surrounded by friends and family who had come to say goodbye.

But at the 11th hour, a battery of blood tests gave the researchers a clue as to what might help save Emma: her level of one of the cytokines, interleukin-6 or IL-6, had shot up a thousandfold. Doctors had never seen such a spike before and thought it might be what was making her so sick.

Dr. June knew that a drug could lower IL-6 — his daughter takes it for rheumatoid arthritis. It had never been used for a crisis like Emma’s, but there was little to lose. Her oncologist, Dr. Stephan A. Grupp, ordered the drug. The response, he said, was “amazing.”

Within hours, Emma began to stabilize. She woke up a week later, on May 2, the day she turned 7; the intensive-care staff sang “Happy Birthday.”

Since then, the research team has used the same drug, tocilizumab, in several other patients.

In patients with lasting remissions after the treatment, the altered T-cells persist in the bloodstream, though in smaller numbers than when they were fighting the disease. Some patients have had the cells for years.

Dr. Michel Sadelain, who conducts similar studies at the Sloan-Kettering Institute, said: “These T-cells are living drugs. With a pill, you take it, it’s eliminated from your body and you have to take it again.” But T-cells, he said, “could potentially be given only once, maybe only once or twice or three times.”

The Pennsylvania researchers said they were surprised to find any big drug company interested in their work, because a new batch of T-cells must be created for each patient — a far cry from the familiar commercial strategy of developing products like Viagra or cholesterol medicines, in which millions of people take the same drug.

Morsi Extends Compromise to Egyptian Opposition

CAIRO — Struggling to quell protests and violence that have threatened to derail a vote on an Islamist-backed draft constitution, President Mohamed Morsi moved Saturday to appease his opponents with a package of concessions just hours after state media reported that he was moving toward imposing a form of martial law to secure the streets and allow the vote.

Mr. Morsi did not budge on a critical demand of the opposition: that he postpone a referendum set for Saturday to approve the new constitution. His Islamist supporters say the charter will lay the foundation for a new democracy and a return to stability. But liberal groups have faulted it for inadequate protection of individual rights and loopholes that could enable Muslim religious authorities to wield new influence and they are asking for a thorough overhaul.

But in a midnight news conference, his prime minister said Mr. Morsi was offering concessions that he had appeared to dismiss out of hand a few days before. He rescinded most of his sweeping Nov. 22 decree that temporarily elevated his decisions above judicial review and offered a convoluted arrangement for the factions to agree in advance on future constitutional amendments that would be added after passage.

His approach, rolled out throughout a confusing day, appeared to indicate a determination to do whatever it takes to get to the referendum. Amid growing concerns among his advisers that the Interior Ministry may be unable to secure either the polls or the institutions of government in the face of violent protests against Mr. Morsi, the state media reported early Saturday that he was moving toward ordering the armed forces to keep order and authorizing its solders to arrest civilians.

Mr. Morsi has not yet formally issued the order reported in the state newspaper Al Ahram, raising the possibility that the announcement was intended as a warning to his opponents. His moves held out little hope of fully resolving the standoff, in part because even before his concessions were announced opposition leaders had ruled out any rushed attempt at a compromise just days before the referendum.

“No mind would accept dialogue at gunpoint,” said Mohamed Abu El Ghar, an opposition leader, alluding to previously floated ideas about last-minute negotiations between factions for amendments.

Nor did his Islamist allies expect his proposals to succeed. Many have said they concluded that much of the secular opposition is primarily interested in obstructing the transition to democracy at all costs, mainly to block the Islamists’ electoral victory. Instead, some privately relished the bind they believed Mr. Morsi had built for the opposition by giving in to some demands and thus, they said privately, forcing their secular opponents to admit they were afraid to take their case to the ballot box.

The military appeared for now to back Mr. Morsi. Midday, a military spokesman read a statement over state television saying the military “realizes its national responsibility for maintaining the supreme interests of the nation and securing and protecting the vital targets, public institutions, and the interests of the innocent citizens.”

Since Mr. Morsi’s decree granting himself sweeping powers until the ratification of a new constitution, there has been an extraordinary breakdown in Egyptian civic life that has destroyed almost any remaining trust between the rival Islamist and secular factions.

Mr. Morsi had insisted that he needed unchecked power to protect against the threat that judges appointed by the ousted president, Hosni Mubarak, might dissolve the constitutional assembly.

But his claim to such unlimited power for even a limited period struck those suspicious of the Islamists as a possible return to autocracy. It recalled broken promises from the Muslim Brotherhood that it would not dominate the parliamentary election or seek the presidency. And his decree set off an immediate backlash.

Hundreds of thousands of protesters accusing Mr. Morsi and his Islamist allies of monopolizing power have poured into the streets. Demonstrators have also attacked more than two dozen Brotherhood offices around the country, including its headquarters, and judges declared a national strike.

Thefts a Concern as Holiday Deliveries Increase

Librado Romero/The New York Times

A driver in Midtown Manhattan on Friday. U.P.S. expects to deliver more than 500 million packages this season, leaving some to fear a rise in thefts.

A pair of brown leather boots was snatched last week from a doorstep in the suburbs of Chicago. A computer disappeared from a front porch in Fort Worth last month, and an iPad case was stolen outside a Long Island home this week.

As the peak of the holiday gift-buying season approaches and more people are ordering online, here is the downside: Grinch-like bandits are swiping the deliveries from doorsteps when families are not home. Some thieves follow U.P.S. and FedEx trucks along their routes and nab the gifts, while others simply drive through residential neighborhoods looking for packages.

In River Forest, Ill., where the police arrested two young men last week, accusing them of stealing deliveries from homes, plainclothes police officers trail U.P.S. trucks to ferret out thieves who may be following them, Cmdr. Jim O’Shea said.

“This is common at this time of year,” Commander O’Shea said. “We’re trying to take a proactive approach to curtail this.”

So far this holiday season, Americans have spent $21.4 billion online, up 14 percent from last year, according to comScore, a research company. U.P.S. alone expects to deliver more than 500 million packages, and with many of them being left on doorsteps, there could be ample opportunity for thieves to strike.

The Better Business Bureau now recommends that customers be proactive, asking their shipping companies for tracking numbers and requiring signatures upon delivery. If they are not at home, customers should ask for their packages to be held at a lobby desk or at a local shipping center, advised Claire Rosenzweig, the president of the group’s New York chapter.

 

There are no national statistics on doorstep thefts, but reports of local episodes abound. In Burbank, Calif., with five reported incidents this year, compared with one last year, two teenagers were arrested last month after they were found trailing a U.P.S. truck. One young man was released, while the other person, Ararat Gevondyan, 19, was charged with receiving stolen property, with his bail set at $10,000.

“It’s a crime of opportunity,” Sgt. Darin Ryburn of the Burbank Police Department said. The burglars are “going through these packages for items that could be resold,” he said.

On Long Island, two young men were arrested this week, suspected of stealing headphones, an iPad case and two pairs of Skechers shoes from homes in the Bay Shore area.

A few of the thefts have been caught by home surveillance cameras set up to catch or deter vandals. A television station in Pasadena, Calif., showed a video of a woman taking a package from a doorstep. The homeowner said she never got the Paula Deen electric salt-and-pepper shaker her sister had sent her.

While it may seem extreme to install cameras to keep an eye on packages, this type of home surveillance has become more common in recent years, said Marc Horowitz, a spokesman for Brickhouse Security. The company’s sales for home security cameras have more than doubled in the past year, he said, as the cameras have become less expensive. A simple motion-activated porch camera costs about $100.

Some camera customers fear the culprit is closer to home, breaking that commandment of the cul-de-sac, Do Not Covet Thy Neighbor’s Flat-Screen TV.

Mr. Horowitz said he had heard reports from his sales representatives that some customers were buying cameras because they suspected neighbors of pilfering packages (or newspapers and plants).

U.P.S. started a program last year called U.P.S. My Choice, which allows a customer to receive an e-mail or text message before a package arrives and reroute it if no one is going to be home.

U.P.S. drivers are also trained to leave packages out of sight, said Natalie Godwin, a company spokeswoman. Ms. Godwin was with a driver in Atlanta on Tuesday when he decided not to leave a package on someone’s stoop because it was clearly an expensive computer monitor. He dropped it off nearby at the apartment complex’s office.

Drivers leave notes telling the tenants where to find packages, Ms. Godwin said. Often, she added, “They’ll use their own judgment.”

Doping at U.S. Tracks Affects Europe’s Taste for Horse Meat

PARIS — For decades, American horses, many of them retired or damaged racehorses, have been shipped to Canada and Mexico, where it is legal to slaughter horses, and then processed and sold for consumption in Europe and beyond.

Christinne Muschi for The New York Times

A slaughterhouse in Saint-André-Avellin, Quebec, where meat is processed for sale in Europe.

Lately, however, European food safety officials have notified Mexican and Canadian slaughterhouses of a growing concern: The meat of American racehorses may be too toxic to eat safely because the horses have been injected repeatedly with drugs.

Despite the fact that racehorses make up only a fraction of the trade in horse meat, the European officials have indicated that they may nonetheless require lifetime medication records for slaughter-bound horses from Canada and Mexico, and perhaps require them to be held on feedlots or some other holding area for six months before they are slaughtered.

In October, Stephan Giguere, the general manager of a major slaughterhouse in Quebec, said he turned away truckloads of horses coming from the United States because his clients were worried about potential drug issues. Mr. Giguere said he told his buyers to stay away from horses coming from American racetracks.

“We don’t want them,” he said. “It’s too risky.”

The action is just the latest indication of the troubled state of American racing and its problems with the doping of horses. Some prominent trainers have been disciplined for using legal and illegal drugs, and horses loaded with painkillers have been breaking down in arresting numbers. Congress has called for reform, and state regulators have begun imposing stricter rules.

But for pure emotional effect, the alarm raised in the international horse-meat marketplace packs a distinctive punch.

Some 138,000 horses were sent to Canada or Mexico in 2010 alone to be turned into meat for Europe and other parts of the world, according to a Government Accountability Office report. Organizations concerned about the welfare of retired racehorses have estimated that anywhere from 10 to 15 percent of the population sent for slaughter may have performed on racetracks in the United States.

“Racehorses are walking pharmacies,” said Dr. Nicholas Dodman, a veterinarian on the faculty of Tufts University and a co-author of a 2010 article that sought to raise concerns about the health risks posed by American racehorses. He said it was reckless to want any of the drugs routinely administered to horses “in your food chain.”

Horses being shipped to Mexico and Canada are by law required to have been free of certain drugs for six months before being slaughtered, and those involved in their shipping must have affidavits proving that. But European Commission officials say the affidavits are easily falsified. As a result, American racehorses often show up in Canada within weeks — sometimes days — of their leaving the racetrack and their steady diets of drugs.

In October, the European Commission’s Directorate General for Health and Consumers found serious problems while auditing the operations of equine slaughter facilities in Mexico, where 80 percent of the horses arrive from the United States. The commission’s report said Mexican officials were not allowed to question the “authenticity or reliability of the sworn statements” about the ostensibly drug-free horses, and thus had no way of verifying whether the horses were tainted by drugs.

“The systems in place for identification, the food-chain information and in particular the affidavits concerning the nontreatment for six months with certain medical substances, both for the horses imported from the U.S. as well as for the Mexican horses, are insufficient to guarantee that standards equivalent to those provided for by E.U. legislation are applied,” the report said.

The authorities in the United States and Canada acknowledge that oversight of the slaughter business is lax. On July 9, the United States Food and Drug Administration sent a warning letter to an Ohio feedlot operator who sells horses for slaughter. The operator, Ronald Andio, was reprimanded for selling a drug-tainted thoroughbred horse to a Canadian slaughterhouse.

The Canadian Food Inspection Agency had tested the carcass of the horse the previous August and found the anti-inflammatory drug phenylbutazone in the muscle and kidney tissues. It also discovered clenbuterol, a widely abused medication for breathing problems that can build muscle by mimicking anabolic steroids.

Because horses are not a traditional food source in the United States, the Food and Drug Administration does not require human food safety information as it considers what drugs can be used legally on horses. Patricia El-Hinnawy, a spokeswoman for the agency, said agency-approved drugs intended for use in horses carried the warning “Do not use in horses intended for human consumption.”

She also said the case against Mr. Andio remained open.

“On the warning letter, the case remains open and no further information can be provided at this time,” Ms. El-Hinnawy said.

Doping at U.S. Tracks Affects Europe’s Taste for Horse Meat

PARIS — For decades, American horses, many of them retired or damaged racehorses, have been shipped to Canada and Mexico, where it is legal to slaughter horses, and then processed and sold for consumption in Europe and beyond.

A slaughterhouse in Saint-André-Avellin, Quebec, where meat is processed for sale in Europe.

Lately, however, European food safety officials have notified Mexican and Canadian slaughterhouses of a growing concern: The meat of American racehorses may be too toxic to eat safely because the horses have been injected repeatedly with drugs.

Despite the fact that racehorses make up only a fraction of the trade in horse meat, the European officials have indicated that they may nonetheless require lifetime medication records for slaughter-bound horses from Canada and Mexico, and perhaps require them to be held on feedlots or some other holding area for six months before they are slaughtered.

In October, Stephan Giguere, the general manager of a major slaughterhouse in Quebec, said he turned away truckloads of horses coming from the United States because his clients were worried about potential drug issues. Mr. Giguere said he told his buyers to stay away from horses coming from American racetracks.

“We don’t want them,” he said. “It’s too risky.”

The action is just the latest indication of the troubled state of American racing and its problems with the doping of horses. Some prominent trainers have been disciplined for using legal and illegal drugs, and horses loaded with painkillers have been breaking down in arresting numbers. Congress has called for reform, and state regulators have begun imposing stricter rules.

But for pure emotional effect, the alarm raised in the international horse-meat marketplace packs a distinctive punch.

Some 138,000 horses were sent to Canada or Mexico in 2010 alone to be turned into meat for Europe and other parts of the world, according to a Government Accountability Office report. Organizations concerned about the welfare of retired racehorses have estimated that anywhere from 10 to 15 percent of the population sent for slaughter may have performed on racetracks in the United States.

“Racehorses are walking pharmacies,” said Dr. Nicholas Dodman, a veterinarian on the faculty of Tufts University and a co-author of a 2010 article that sought to raise concerns about the health risks posed by American racehorses. He said it was reckless to want any of the drugs routinely administered to horses “in your food chain.”

Horses being shipped to Mexico and Canada are by law required to have been free of certain drugs for six months before being slaughtered, and those involved in their shipping must have affidavits proving that. But European Commission officials say the affidavits are easily falsified. As a result, American racehorses often show up in Canada within weeks — sometimes days — of their leaving the racetrack and their steady diets of drugs.

In October, the European Commission’s Directorate General for Health and Consumers found serious problems while auditing the operations of equine slaughter facilities in Mexico, where 80 percent of the horses arrive from the United States. The commission’s report said Mexican officials were not allowed to question the “authenticity or reliability of the sworn statements” about the ostensibly drug-free horses, and thus had no way of verifying whether the horses were tainted by drugs.

As Egypt’s Crisis Deepens, Morsi Turns to Muslim Brotherhood

CAIRO — Facing the most serious crisis of his presidency, Mohamed Morsi is leaning more closely than ever on his Islamist allies in the Muslim Brotherhood, betting on their political muscle to push through a decisive victory in the referendum on Egypt’s divisive draft constitution.

As tens of thousands chanted for his downfall or even imprisonment in a fourth day of protests outside the presidential palace, Mr. Morsi’s advisers and Brotherhood leaders acknowledged Friday that outside his core base of Islamist supporters he feels increasingly isolated in the political arena and even within his own government. The Brotherhood “is who he can depend on,” said one person close to Mr. Morsi, speaking on the condition of anonymity to discuss internal deliberations. Mr. Morsi appeared to believe that he and the Brotherhood could deliver a strong vote for the draft constitution in next Saturday’s referendum — strong enough to discredit the opposition, allow him a fresh start and restore some of his authority.

Struggling to quell protests and violence around the country, Mr. Morsi appeared to offer a new concession to his opponents Friday by opening the door to a possible delay in the referendum on the draft constitution, now scheduled for Dec. 15, and even potential revisions by the Islamist-dominated constitutional assembly. But opposition leaders turned a deaf ear, reiterating their demands to begin an overhaul of the assembly itself.

“He has to take these steps, and I hope that he listens to us,” Mohamed ElBaradei, the former United Nations diplomat and coordinator of the opposition front, said Friday in televised response.

But Mr. Morsi’s advisers said he held out little hope of reaching a compromise and instead remained reliant on rallying his Islamist base, a strategy he displayed most vividly in a televised speech to the nation Thursday night. Addressing clashes between his Islamist supporters and their opponents that had killed at least six, Mr. Morsi all but declined to play the unifier, something he could have accomplished by sympathizing equally with those injured or killed on either side.

Instead, he struck the themes with the most resonance to his Islamist supporters, arguing that his backers outside the palace had come under attack by hired thugs paid with “black money” from a conspiracy of loyalists to the ousted president, Hosni Mubarak, and foreign interests determined to thwart the revolution. And he also said that some of the culprits had “direct links” to the political opposition, calling on Egyptians “to stand up to these heinous crimes.”

Mr. Morsi’s turn back toward his Islamist base is a bet that the Brotherhood’s political machine can easily overcome even the re-energized secular opposition. And his advisers argue that the achievement of even an imperfect constitution will prove his commitment to the democratic rule of law and restore his credibility. But it also contributes to the paralyzing polarization now gripping Egyptian politics. It risks tarnishing both the Constitution and Mr. Morsi as purely partisan and unable to represent all Egyptians. And it makes Mr. Morsi even more dependent on the same insular group that plucked him from anonymity and propelled him to the presidency.

The result could be a hollow victory that perpetuates the instability of the political transition. “O.K., so you will have the referendum on Dec. 15 and you will end up with a ‘yes’ vote,” said Khaled Fahmy, a historian at the American University in Cairo. “On Dec. 16, Egypt will be infinitely more difficult to govern than it already is now.”

Some senior Brotherhood leaders have acknowledged that the bruising battle may hurt their party’s fortunes in the next parliamentary elections, which are set for February if the constitution passes. “I don’t think we will have the same level of trust, and I think our numbers will probably be affected,” one senior Brotherhood leader said Friday, speaking on the condition of anonymity to discuss internal deliberations.

European Panel Is Pressuring Google on Privacy Rules

European data protection officials are drafting plans to censure Google over its online privacy policy if the company does not meet the demands of regulators to revise it.

In a two-day closed-door meeting this week in Brussels of the European Union’s 27 national data protection officials, the group mapped a preliminary strategy, including the possibility of testing Google’s compliance with national privacy laws in countries like Ireland, Belgium and Finland, where the company operates data centers. That was the word from a person close to the discussions, who spoke on condition of anonymity.

The group may issue a public statement next week on the matter.

The group is focusing on new guidelines Google adopted this year for collecting information on individuals. Under the new policy, when people are logged into a Google account, the company can use information shared on one service in other Google services. For example, Google could show people an ad on YouTube based on what they have searched for, or fix the spelling of a friend’s name in a Google search based on information from Gmail.

When the guidelines were announced, they were sharply criticized in Europe. Data protection officials from various countries asked the French regulator, C.N.I.L., to study them. In mid-October, that regulator released a report criticizing the guidelines as allowing an “uncontrolled combination of data.”

The 27 European regulators wrote a letter to Larry Page, the chief executive of Google, asking the company to modify the new policy, which governs dozens of Google services — among them the search engine, Android mobile phone apps and YouTube videos. The regulators want Google to give users a better sense of what personal data is being collected and to allow them to better control how that information is shared with advertisers.

C.N.I.L. said the method of combining information from Google’s search engine, YouTube, the Google Plus social network and other services “suggests the absence of any limit concerning the scope of collection and the potential uses of the personal data.”

Google made nearly all of its $37.9 billion in sales revenue in 2011 from Internet advertising, which relies in part on the collection and analysis of user data to produce ads aimed at individual consumers.

When C.N.I.L. released its report, Google said it would study the analysis. But the company also asserted that its method of handling consumer data was legal under European Union rules. At a conference in Arizona in October, Mr. Page defended the guidelines.

So far the company, which also ran afoul of European regulators in 2010 for its collection of personal data from home Wi-Fi routers in the Street View controversy, has not responded formally to the report by the French regulator.

On Friday, a Google spokesman in Brussels, Alistair Verney, referred to the company’s previous statement in October, which said Google was reviewing the French recommendations. “Our new privacy policy demonstrates our longstanding commitment to protecting our users’ information and creating great products,” the Google statement said at the time. “We are confident that our privacy notices respect European law.”

When C.N.I.L. presented its analysis in October, the chairwoman of the French regulator, Isabelle Falque-Pierrotin, gave the search engine “three to four months” — roughly until mid-February — to respond to its recommendations.

Among other things, C.N.I.L. asked Google to heed European restrictions on mixing certain data and to heed Europe’s rules for obtaining consent from consumers before collecting personal data.

Google users in Europe cannot use the search engine’s services unless they agree to accept the company’s privacy policy.

But C.N.I.L. argued in its review that the opt-in disclaimer, which is legal under United States law, was too broad. It also said consumers should be given clearer information and be allowed to individually authorize or reject the collection of certain kinds of data.

While European lawmakers coordinate European Union data protection from Brussels, privacy law is enforced on the national level.

That decentralization is why regulators are considering taking action within a few nations — most likely in countries where Google has physical operations and where national courts could be asked to enforce penalties.

But whether any actions, if they do eventually take place, result in anything other than minor sanctions remains to be seen. In general, European national regulators are limited to privacy violation fines of only a few hundred thousand euros against companies or individuals.

A proposed update to European Union data protection law would give regulators the ability to assess much larger fines of as much as 2 percent of a company’s annual sales — which based on Google’s financial performance would equate to about $760 million, based on 2011 revenue of $37.9 billion.

But it is unclear how soon, if ever, those higher penalties will be adopted.

Another person with knowledge of the regulators’ discussion this week emphasized that the group was still hoping Google would adapt its rules in Europe to conform with the Continent’s restrictions on data mining.

“We still have a lot of time left before we come to this juncture,” said another person with knowledge of the group’s discussions, citing the spring deadline for Google’s formal response. “Let’s wait and see what happens.”
