Protests Grow on Fifth Day of Unrest in Egypt

Tara Todras-Whitehill for The New York Times

Egyptians in Port Said mourned on Monday for people killed in clashes with the police a day earlier.

PORT SAID, Egypt — The police fired indiscriminately into the streets outside their besieged station, a group of protesters arrived with a crate of gasoline bombs, and others cheered a masked man on a motorcycle who arrived with a Kalashnikov.

The growing chaos along the vital canal zone showed little sign of abating on Monday as President Mohamed Morsi called out the army to try to regain control of three cities along the Suez Canal whose growing lawlessness is testing the integrity of the Egyptian state.

In Port Said, street battles reached a bloody new peak with a death toll over three days of at least 45, with at least five more protesters killed by bullet wounds, hospital officials said.

Such violence has flared across Egypt with increasing frequency since President Hosni Mubarak was forced out by the revolution two years ago.

President Morsi had already declared a monthlong state of emergency here and in the other canal towns of Suez and Ismailia, applying a Mubarak-era law that virtually eliminates due process protections against abuse by the police. Angry crowds burned tires and hurled rocks at the police. And the police, with little training and less credibility, hunkered down behind barrages of tear gas, birdshot and occasional bullets.

The sense that the state was unraveling may have been strongest here in Port Said, where demonstrators have proclaimed their city an independent nation. But in recent days the unrest has risen in towns across the country and in Cairo as well. In the capital on Monday, a mob of protesters managed to steal an armored police vehicle, drive it to Tahrir Square and make it a bonfire.

After two years of torturous transition, Egyptians have watched with growing anxiety as the erosion of the public trust in the government and a persistent security vacuum have fostered a new temptation to resort to violence to resolve disputes, said Michael Hanna, a researcher at the New York-based Century Foundation who is now in Cairo. “There is a clear political crisis that has eroded the moral authority of the state,” he said.

And the spectacular evaporation of the government’s authority here in Port Said has put that crisis on vivid display, most conspicuously in the rejection of Mr. Morsi’s declarations of the curfew and state of emergency.

As in Suez and Ismailia, tens of thousands residents of Port Said poured into the streets in defiance just as a 9 p.m. curfew was set to begin. Bursts of gunfire echoed through the city for the next hours, and between 9 and 11 p.m. hospital officials raised the death count to seven from two.

When two armored personnel carriers approached a funeral Monday morning for some of the seven protesters killed the day before, a stone-throwing mob of thousands quickly chased them away. And within a few hours the demonstrators had resumed their siege of a nearby police station, burning tires to create a smoke screen to hide behind amid tear gas and gunfire.

Many in the city said they saw no alternative but to continue to stay in the streets. They complained that the hated security police remained unchanged and unaccountable even after Mr. Mubarak had been ousted. They saw no recourse in the justice system, which is also unchanged; they dismissed the courts as politicized, especially after the acquittals of all those accused of killing protesters during the revolution. Then came the death sentences handed down Saturday to 21 Port Said soccer fans for their role in a deadly brawl. The death sentences set off the current unrest here.

Nor, they said, did they trust the political process that brought to power Mr. Morsi and his Islamist allies in the Muslim Brotherhood. He had vowed to usher in the rule of law as “a president for all Egyptians.” But in November he used a presidential decree to temporarily stifle potential legal objections so that his Islamist allies could rushed out a new Constitution. His authoritarian move kicked off a sharp uptick in street violence leading to this weekend’s Port Said clashes.

“Injustice beyond imagination,” one man outside the morning funeral said of Mr. Morsi’s emergency decree, before he was drowned out a crowd of others echoing the sentiment.

“He declared a curfew, and we declare civil disobedience,” another man said.

“This doesn’t apply to Port Said because we don’t recognize him as our president,” said a third. “He is the president of the Muslim Brotherhood only.”

Yahoo Earnings Handily Beat Forecasts

SAN FRANCISCO — Marissa Mayer, just by being Marissa Mayer, has done more to move Yahoo forward in her first six months as chief executive than any of her five predecessors did over as many years.

An accomplished engineer and executive, Ms. Mayer joined Yahoo from Google as a Silicon Valley celebrity. Since then, just her presence at the company’s Sunnyvale, Calif., headquarters seems to have jolted Yahoo back to life. On Monday, Yahoo reported a good quarter, increasing revenue for the first time in four years and beating Wall Street expectations by 30 percent.

That pushed Yahoo’s stock to $20.91 in after-hours trading — a four-year high (but still well below the $31 Microsoft offered the company back in 2008).

Ms. Mayer attributed growth to a renewed focus on “people and products” in a call with analysts on Monday.

She has added new Yahoo fans by revamping Yahoo’s e-mail service and redesigning Flickr, the firm’s photo-sharing app, which sent the number of photo uploads rising 25 percent. Ms. Mayer said those improvements were a hint of more under way.

“We are off to a very good start,” Ms. Mayer told analysts. “We are making the world’s habits more inspiring and entertaining.”

She has also introduced several morale boosters since joining the company — including free cafeteria food and new iPhones and Android-powered phones — to staff members who were more accustomed to cost cutting and layoffs. In a further sign that the company was no longer considered a sinking ship, she lured another Silicon Valley tech star, Max Levchin, a PayPal co-founder, to Yahoo’s board last month.

But those were just the office things. Analysts were more impressed with improvements to the company’s search business. Yahoo outsourced it to Microsoft in 2009 and it has languished ever since, propped up only because of a revenue-guarantee clause in its contract with Microsoft that is set to expire in March. Yahoo’s search revenue rose 4 percent in the fourth quarter, to $482 million, compared with $465 million for the period a year earlier.

Over all, Yahoo reported net income in the fourth quarter of $272.3 million, or 23 cents a share, compared with $295.6 million, or 24 cents a share, in the period a year earlier.

The company said revenue was up 1.6 percent, to $1.35 billion.

The improvement to its search business was offset by continued declines in Yahoo’s display ad revenue. The company said it made $591 million in display ad sales last quarter, a 3 percent decline from the $612 million in the quarter a year ago.

Yahoo, once the biggest seller of display ads in the United States, went from a leading 15.5 percent share of all digital ad revenues in the United States in 2009, to an 8.4 percent share last year, even as total digital ad spending grew, according to eMarketer. Meanwhile, its competitor, Google, increased its share to 41 percent.

“More personalized content and increased product innovation will be key to getting us back to the path for display revenue growth,” Ms. Mayer said on the call.

The fourth-quarter results impressed analysts, but many remained skeptical.

“Marissa will have to protect Yahoo’s legacy business while positioning the company for future growth,” Colin Gillis, an Internet analyst at BGC Partners, said in an interview Monday. “That is not easy.”

With Ms. Mayer’s honeymoon with Wall Street expected to end soon, investors are eager to see whether she can deliver sustained growth. Yahoo, with 700 million monthly users, commands one of the largest audiences on the Web. But the company, an Internet pioneer, has been unable to attract advertisers and increase revenue.

As Ms. Mayer has acknowledged, Yahoo’s future growth may well depend on its mobile strategy. And without mobile hardware like a tablet computer, a browser or a social networking platform of its own, Yahoo has a long way to go.

The company continues to be outspent in research and development by Google, Apple, Facebook and Amazon. It also continues to have a hard time convincing Silicon Valley’s engineering talent to join Yahoo instead of its competitors.

Ms. Mayer has said Yahoo’s mobile growth may come from acquisitions of mobile app companies. In six months, Ms. Mayer has acquired three start-ups — Stamped, OnTheAir and Snip.it — for undisclosed sums, more for the engineering talent than the products.

“The road will only get harder,” said Mr. Gillis. But compared to Ms. Mayer’s disgraced immediate predecessor, Scott Thompson, who left the company after four months over embellishments on his résumé, Mr. Gillis added, “at least she got a honeymoon.”

This article has been revised to reflect the following correction:

Correction: January 28, 2013

Because of an editing error, an earlier version of this article misstated the percentage increase in Yahoo’s quarterly revenue. It was 1.6 percent, not 1.5 percent.

Personal Health: Keeping Blood Pressure in Check

Since the start of the 21st century, Americans have made great progress in controlling high blood pressure, though it remains a leading cause of heart attacks, strokes, congestive heart failure and kidney disease.

Now 48 percent of the more than 76 million adults with hypertension have it under control, up from 29 percent in 2000.

But that means more than half, including many receiving treatment, have blood pressure that remains too high to be healthy. (A normal blood pressure is lower than 120 over 80.) With a plethora of drugs available to normalize blood pressure, why are so many people still at increased risk of disease, disability and premature death? Hypertension experts offer a few common, and correctable, reasons:

---

Jane Brody speaks about hypertension.

---

¶ About 20 percent of affected adults don’t know they have high blood pressure, perhaps because they never or rarely see a doctor who checks their pressure.

¶ Of the 80 percent who are aware of their condition, some don’t appreciate how serious it can be and fail to get treated, even when their doctors say they should.

¶ Some who have been treated develop bothersome side effects, causing them to abandon therapy or to use it haphazardly.

¶ Many others do little to change lifestyle factors, like obesity, lack of exercise and a high-salt diet, that can make hypertension harder to control.

Dr. Samuel J. Mann, a hypertension specialist and professor of clinical medicine at Weill-Cornell Medical College, adds another factor that may be the most important. Of the 71 percent of people with hypertension who are currently being treated, too many are taking the wrong drugs or the wrong dosages of the right ones.

Dr. Mann, author of “Hypertension and You: Old Drugs, New Drugs, and the Right Drugs for Your High Blood Pressure,” says that doctors should take into account the underlying causes of each patient’s blood pressure problem and the side effects that may prompt patients to abandon therapy. He has found that when treatment is tailored to the individual, nearly all cases of high blood pressure can be brought and kept under control with available drugs.

Plus, he said in an interview, it can be done with minimal, if any, side effects and at a reasonable cost.

“For most people, no new drugs need to be developed,” Dr. Mann said. “What we need, in terms of medication, is already out there. We just need to use it better.”

But many doctors who are generalists do not understand the “intricacies and nuances” of the dozens of available medications to determine which is appropriate to a certain patient.

“Prescribing the same medication to patient after patient just does not cut it,” Dr. Mann wrote in his book.

The trick to prescribing the best treatment for each patient is to first determine which of three mechanisms, or combination of mechanisms, is responsible for a patient’s hypertension, he said.

¶ Salt-sensitive hypertension, more common in older people and African-Americans, responds well to diuretics and calcium channel blockers.

¶ Hypertension driven by the kidney hormone renin responds best to ACE inhibitors and angiotensin receptor blockers, as well as direct renin inhibitors and beta-blockers.

¶ Neurogenic hypertension is a product of the sympathetic nervous system and is best treated with beta-blockers, alpha-blockers and drugs like clonidine.

According to Dr. Mann, neurogenic hypertension results from repressed emotions. He has found that many patients with it suffered trauma early in life or abuse. They seem calm and content on the surface but continually suppress their distress, he said.

One of Dr. Mann’s patients had had high blood pressure since her late 20s that remained well-controlled by the three drugs her family doctor prescribed. Then in her 40s, periodic checks showed it was often too high. When taking more of the prescribed medication did not result in lasting control, she sought Dr. Mann’s help.

After a thorough work-up, he said she had a textbook case of neurogenic hypertension, was taking too much medication and needed different drugs. Her condition soon became far better managed, with side effects she could easily tolerate, and she no longer feared she would die young of a heart attack or stroke.

But most patients should not have to consult a specialist. They can be well-treated by an internist or family physician who approaches the condition systematically, Dr. Mann said. Patients should be started on low doses of one or more drugs, including a diuretic; the dosage or number of drugs can be slowly increased as needed to achieve a normal pressure.

Specialists, he said, are most useful for treating the 10 percent to 15 percent of patients with so-called resistant hypertension that remains uncontrolled despite treatment with three drugs, including a diuretic, and for those whose treatment is effective but causing distressing side effects.

Hypertension sometimes fails to respond to routine care, he noted, because it results from an underlying medical problem that needs to be addressed.

“Some patients are on a lot of blood pressure drugs — four or five — who probably don’t need so many, and if they do, the question is why,” Dr. Mann said.

How to Measure Your Blood Pressure

Mistaken readings, which can occur in doctors’ offices as well as at home, can result in misdiagnosis of hypertension and improper treatment. Dr. Samuel J. Mann, of Weill Cornell Medical College, suggests these guidelines to reduce the risk of errors:

¶ Use an automatic monitor rather than a manual one, and check the accuracy of your home monitor at the doctor’s office.

¶ Use a monitor with an arm cuff, not a wrist or finger cuff, and use a large cuff if you have a large arm.

¶ Sit quietly for a few minutes, without talking, after putting on the cuff and before checking your pressure.

¶ Check your pressure in one arm only, and take three readings (not more) one or two minutes apart.

¶ Measure your blood pressure no more than twice a week unless you have severe hypertension or are changing medications.

¶ Check your pressure at random, ordinary times of the day, not just when you think it is high.

Media Decoder: Tsujihara to Succeed Meyer as Head of Warner Brothers

LOS ANGELES — Kevin Tsujihara will succeed Barry M. Meyer as chief executive of Warner Brothers, the studio announced on Monday, ending a disruptive and lingering competition for one of the biggest jobs in Hollywood. But, with two senior Warner executives publicly passed over, disorder at the studio could continue.

Home to Batman, Bugs Bunny, “Two and a Half Men” and TMZ.com, Warner is Hollywood’s largest movie and television studio. It has also been the industry’s most stable. Mr. Meyer, who is retiring, has led Warner since 1999; a single management team oversaw the studio for the previous 18 years.

A two-year succession contest, however, has brought escalating internal tension, a slowing of routine business and low morale, according to Warner employees and people who have had business dealings with the company. Jeffrey L. Bewkes, chief executive of Time Warner, moved on Monday to end that distraction by promoting Mr. Tsujihara, 48. Scheduled to take over on March 1, Mr. Tsujihara most recently ran Warner’s home entertainment unit, which includes video games and the online distribution of movies and television shows.

“Kevin’s experience is very balanced and has touched all parts of Warner,” Mr. Bewkes said in a telephone interview. “He also has the right temperament to be an effective unifier and leader.”

Mr. Tsujihara immediately faces the challenge of retaining the two executives he beat out for the job. They are Bruce Rosenblum, president of Warner Television, and Jeffrey Robinov, president of Warner’s movie division. Mr. Bewkes said he wanted to “keep everybody on the field,” adding that Mr. Rosenblum and Mr. Robinov both have “very big, full jobs.”

Even so, Mr. Rosenblum, who runs Warner’s most profitable division and had been seen by many in Hollywood as the leading candidate to succeed Mr. Meyer, did not hide his displeasure at losing. “Obviously, I’m disappointed; who wouldn’t be?” he said in a statement. He added that Warner “will be in good hands with Kevin.”

Mr. Robinov was more effusive about his new boss. “I am truly happy and proud of Kevin,” he said in a separate statement. “We are both good friends and colleagues, and I think he’s an excellent choice for the job.”

Will Mr. Rosenblum and Mr. Robinov ultimately leave? “We both hope they will stay and support Kevin,” Mr. Meyer, 69, said in a telephone interview. He added, however, “This is news to everybody, and I think they’re thinking it over.”

In some ways, Mr. Tsujihara’s ascendance can be seen as a clear statement of what Time Warner thinks its studio most needs to face the challenges ahead.

While he is respected in Hollywood’s creative community of producers, writers, directors and agents, Mr. Tsujihara does not come from the trenches. Instead, he has been grappling with the Web as a disrupter of distribution and business models. He has also been Warner’s point person on piracy.

Mr. Meyer said Mr. Tsujihara’s qualifications went well beyond that. Calling Mr. Tsujihara “deliberate and thoughtful,” he underscored his successor’s creative skill. In recent years, for instance, Mr. Tsujihara has played a role in deciding what movies Warner puts into production, even routinely reading scripts, Mr. Meyer said. Mr. Tsujihara was also the executive that Warner dispatched to New Zealand in 2010 to solve a labor dispute that threatened “The Hobbit: An Unexpected Journey” and two sequels.

Speaking by telephone, Mr. Tsujihara said his immediate plans are “to do a lot of listening” and to work with his former rivals to “create the right transition and the right organizational structure moving forward.”

“I’m coming in at a great time, not a time when we have to make massive changes because we’re not successful,” he said.

Warner, which was founded in 1923, produces more than 50 television programs for various networks, including “The Ellen DeGeneres Show,” “The Middle” and “The Mentalist.” Last year Warner movies took in about $4.3 billion at the global box office, with hits that included “The Dark Knight Rises” and “Magic Mike.”

Still, the studio faces significant competition in television production from 20th Century Fox and has struggled to bring its stable of DC Comics superheroes — Wonder Woman, Green Lantern, the Flash — to movie audiences as Disney’s Marvel Studios has introduced one superhero hit after another.

Mr. Tsujihara joined Warner in 1994 to help with its interest in the Six Flags theme parks. Before taking over home entertainment in 2005, he worked in the studio’s business development and strategy department.

Morsi Declares Emergency in 3 Egypt Cities as Unrest Spreads

Tara Todras-Whitehill for The New York Times

An Egyptian man threw a tear-gas canister back at the police in Port Said on Sunday.

PORT SAID, Egypt — President Mohamed Morsi declared a state of emergency and a curfew in three major cities on Sunday, as escalating violence in the streets threatened his government and Egypt’s democracy.

By imposing a one-month state of emergency in Suez, Ismailia and here in Port Said, where the police have lost all control, Mr. Morsi’s declaration chose to use one of the most despised weapons of former President Hosni Mubarak’s autocracy. Under Mubarak-era laws left in effect by the country’s new Constitution, a state of emergency suspends the ordinary judicial process and most civil rights. It gives the president and the police extraordinary powers.

Mr. Morsi, Egypt’s first freely elected president and a leader of the political arm of the Muslim Brotherhood, took the step after four days of clashes in Cairo and in cities around the country between the police and protesters denouncing his government. Most of the protests were set off by the second anniversary of the popular revolt that ousted Mr. Mubarak, which fell on Friday.

Here in Port Said, the trouble started over death sentences that a court imposed on 21 local soccer fans for their role in a deadly riot. But after 30 people died in clashes on Saturday — most of them shot by the police — the protesters turned their ire on Mr. Morsi as well the court. Police officers crouching on the roofs of their stations fired tear gas and live ammunition into attacking mobs, and hospital officials said that on Sunday at least seven more people died. Tens of thousands of people marched through the streets of Port Said on Sunday demanding independence from the rest of Egypt. “The people want the state of Port Said,” they chanted in anger at Cairo.

The emergency declaration covers the three cities and their surrounding provinces, all on the economically vital Suez Canal. Mr. Morsi announced the emergency measures in a stern, finger-waving speech on state television on Sunday evening. He said he was acting “to stop the bloodbath” and called the violence in the streets “the counterrevolution itself.”

“There is no room for hesitation, so that everybody knows the institution of the state is capable of protecting the citizens,” he said. “If I see that the homeland and its children are in danger, I will be forced to do more than that. For the sake of Egypt, I will.”

Mr. Morsi’s resort to the authoritarian measures of his predecessor appeared to reflect mounting doubts about the viability of Egypt’s central government. After decades of corruption, cronyism and brutality under Mr. Mubarak, Egyptians have struggled to adjust to resolving their differences — whether over matters of political ideology or crime and punishment — through peaceful democratic channels.

“Why are we unable to sort out these disputes?” asked Moattaz Abdel-Fattah, a political scientist and academic who was a member of the assembly that drafted Egypt’s new Constitution. “How many times are we going to return to the state of Egyptians killing Egyptians?” He added: “Hopefully, when you have a genuine democratic machine, people will start to adapt culturally. But we need to do something about our culture.”

Mr. Morsi’s speech did nothing to stop the violence in the streets. In Cairo, fighting between protesters and the police and security forces escalated into the night along the banks of the Nile near Tahrir Square. On a stage set up in the square, liberal and leftist speakers demanded the repeal of the Islamist-backed Constitution, which won approval in a referendum last month. Young men huddled in tents making incendiary devices, while others set tires on fire to block a main bridge across the Nile.

In Suez, a group calling itself the city’s youth coalition said it would hold nightly protests against the curfew at the time it begins, 9 p.m. In Port Said, crowds began to gather just before the declaration was set to take effect, at midnight, for a new march in defiance.

“We will gather every night at 9 at Mariam’s mosque,” said Ahmed Mansour, a doctor. “We will march all night long until morning.”

He added: “Morsi is an employee who works for us. He must do what suits us, and this needs to be made clear.”

Mayy El-Sheikh contributed reporting from Port Said, and Kareem Fahim from Cairo.

Unboxed: Literary History, Seen Through Big Data’s Lens

ANY list of the leading novelists of the 19th century, writing in English, would almost surely include Charles Dickens, Thomas Hardy, Herman Melville, Nathaniel Hawthorne and Mark Twain.

But they do not appear at the top of a list of the most influential writers of their time. Instead, a recent study has found, Jane Austen, author of “Pride and Prejudice, “ and Sir Walter Scott, the creator of “Ivanhoe,” had the greatest effect on other authors, in terms of writing style and themes.

These two were “the literary equivalent of Homo erectus, or, if you prefer, Adam and Eve,” Matthew L. Jockers wrote in research published last year. He based his conclusion on an analysis of 3,592 works published from 1780 to 1900. It was a lot of digging, and a computer did it.

The study, which involved statistical parsing and aggregation of thousands of novels, made other striking observations. For example, Austen’s works cluster tightly together in style and theme, while those of George Eliot (a k a Mary Ann Evans) range more broadly, and more closely resemble the patterns of male writers. Using similar criteria, Harriet Beecher Stowe was 20 years ahead of her time, said Mr. Jockers, whose research will soon be published in a book, “Macroanalysis: Digital Methods and Literary History” (University of Illinois Press).

These findings are hardly the last word. At this stage, this kind of digital analysis is mostly an intriguing sign that Big Data technology is steadily pushing beyond the Internet industry and scientific research into seemingly foreign fields like the social sciences and the humanities. The new tools of discovery provide a fresh look at culture, much as the microscope gave us a closer look at the subtleties of life and the telescope opened the way to faraway galaxies.

“Traditionally, literary history was done by studying a relative handful of texts,” says Mr. Jockers, an assistant professor of English and a researcher at the Center for Digital Research in the Humanities at the University of Nebraska. “What this technology does is let you see the big picture — the context in which a writer worked — on a scale we’ve never seen before.”

Mr. Jockers, 46, personifies the digital advance in the humanities. He received a Ph.D. in English literature from Southern Illinois University, but was also fascinated by computing and became a self-taught programmer. Before he moved to the University of Nebraska last year, he spent more than a decade at Stanford, where he was a founder of the Stanford Literary Lab, which is dedicated to the digital exploration of books.

Today, Mr. Jockers describes the tools of his trade in terms familiar to an Internet software engineer — algorithms that use machine learning and network analysis techniques. His mathematical models are tailored to identify word patterns and thematic elements in written text. The number and strength of links among novels determine influence, much the way Google ranks Web sites.

It is this ability to collect, measure and analyze data for meaningful insights that is the promise of Big Data technology. In the humanities and social sciences, the flood of new data comes from many sources including books scanned into digital form, Web sites, blog posts and social network communications.

Data-centric specialties are growing fast, giving rise to a new vocabulary. In political science, this quantitative analysis is called political methodology. In history, there is cliometrics, which applies econometrics to history. In literature, stylometry is the study of an author’s writing style, and these days it leans heavily on computing and statistical analysis. Culturomics is the umbrella term used to describe rigorous quantitative inquiries in the social sciences and humanities.

“Some call it computer science and some call it statistics, but the essence is that these algorithmic methods are increasingly part of every discipline now,” says Gary King, director of the Institute for Quantitative Social Science at Harvard.

Cultural data analysts often adapt biological analogies to describe their work. Mr. Jockers, for example, called his research presentation “Computing and Visualizing the 19th-Century Literary Genome.”

Such biological metaphors seem apt, because much of the research is a quantitative examination of words. Just as genes are the fundamental building blocks of biology, words are the raw material of ideas.

“What is critical and distinctive to human evolution is ideas, and how they evolve,” says Jean-Baptiste Michel, a postdoctoral fellow at Harvard.

Mr. Michel and another researcher, Erez Lieberman Aiden, led a project to mine the virtual book depository known as Google Books and to track the use of words over time, compare related words and even graph them.

Google cooperated and built the software for making graphs open to the public. The initial version of Google’s cultural exploration site began at the end of 2010, based on more than five million books, dating from 1500. By now, Google has scanned 20 million books, and the site is used 50 times a minute. For example, type in “women” in comparison to “men,” and you see that for centuries the number of references to men dwarfed those for women. The crossover came in 1985, with women ahead ever since.

In work published in Science magazine in 2011, Mr. Michel and the research team tapped the Google Books data to find how quickly the past fades from books. For instance, references to “1880,” which peaked in that year, fell to half by 1912, a lag of 32 years. By contrast, “1973” declined to half its peak by 1983, only 10 years later. “We are forgetting our past faster with each passing year,” the authors wrote.

JON KLEINBERG, a computer scientist at Cornell, and a group of researchers approached collective memory from a very different perspective.

Ariel Sharon Brain Scan Shows Response to Stimuli

JERUSALEM — A brain scan performed on Ariel Sharon, the former Israeli prime minister who had a devastating stroke seven years ago and is presumed to be in a vegetative state, revealed significant brain activity in response to external stimuli, raising the chances that he is able to hear and understand, a scientist involved in the test said Sunday.

Scientists showed Mr. Sharon, 84, pictures of his family, had him listen to a recording of the voice of one of his sons and used tactile stimulation to assess the extent of his brain’s response.

“We were surprised that there was activity in the proper parts of the brain,” said Prof. Alon Friedman, a neuroscientist at Ben-Gurion University of the Negev and a member of the team that carried out the test. “It raises the chances that he hears and understands, but we cannot be sure. The test did not prove that.”

The activity in specific regions of the brain indicated appropriate processing of the stimulations, according to a statement from Ben-Gurion University, but additional tests to assess Mr. Sharon’s level of consciousness were less conclusive.

“While there were some encouraging signs, these were subtle and not as strong,” the statement added.

The test was carried out last week at the Soroka University Medical Center in the southern Israeli city of Beersheba using a state-of-the-art M.R.I. machine and methods recently developed by Prof. Martin M. Monti of the University of California, Los Angeles. Professor Monti took part in the test, which lasted approximately two hours.

Mr. Sharon’s son Gilad said in October 2011 that he believed that his father responded to some requests. “When he is awake, he looks at me and moves fingers when I ask him to,” he said at the time, adding, “I am sure he hears me.”

Professor Friedman said in a telephone interview that the test results “say nothing about the future” but may be of some help to the family and the regular medical staff caring for Mr. Sharon at a hospital outside Tel Aviv.

“There is a small chance that he is conscious but has no way of expressing it,” Professor Friedman said, but he added, “We do not know to what extent he is conscious.”

Stanley Karnow, Historian and Journalist, Is Dead at 87

Stanley Karnow, a Pulitzer Prize-winning historian and journalist who produced acclaimed books and television documentaries about Vietnam and the Philippines in the throes of war and upheaval, died on Sunday at his home in Potomac, Md. He was 87.

The cause was congestive heart failure, said Mr. Karnow’s son, Michael.

For more than three decades Mr. Karnow was a correspondent in Southeast Asia, working for Time, Life, The Saturday Evening Post, The Washington Post, NBC News, The New Republic, King Features Syndicate and the Public Broadcasting Service. But he was best known for his books and documentaries.

He was in Vietnam in 1959, when the first American advisers were killed, and lingered long after the guns fell silent, talking to fighters, villagers, refugees, North and South Vietnamese political and military leaders, the French and the Americans, researching a people and a war that had been little understood.

The result was the 750-page book “Vietnam: A History,” published in 1983, and its companion, a 13-hour PBS documentary, “Vietnam: A Television History.” Unlike many books and films on Vietnam in the 1960s and ’70s and the nightly newscasts that focused primarily on America’s role and its consequences at home and abroad, Mr. Karnow addressed all sides of the conflict and traced Vietnam’s culture and history.

“Vietnam: A History” was widely praised and a best seller. The documentary, with Mr. Karnow as chief correspondent, was at the time the most successful ever produced by public television, viewed by an average of nearly 10 million people a night through 13 episodes. It won six Emmy Awards, as well as Peabody, Polk and duPont-Columbia awards.

Six years later, Mr. Karnow delivered his second comprehensive book and television examination of a Southeast Asian nation. The book, “In Our Image: America’s Empire in the Philippines” (1989), was a panorama of centuries of Filipino life under Spanish and American colonial rule, followed by independence under sometimes corrupt American-backed leaders. It won the 1990 Pulitzer Prize for history.

Narrated by Mr. Karnow, the three-part PBS documentary “The U.S. and the Philippines: In Our Image” traced America’s paternalistic colonial rule in the Philippines, the shared suffering of Filipinos and Americans under a cruel Japanese occupation in World War II, and Manila’s postwar independence under regimes nominally democratic but repressive, corrupt or indifferent to the miseries of its people.

Mr. Karnow also wrote “Mao and China: From Revolution to Revolution” (1972) and was a co-author of or contributor to books based on his years in Asia, including “Asian-Americans in Transition” (1992), “Passage to Vietnam” (1994), “Mekong” (1995) and “Historical Atlas of the Vietnam War” (1995).

Early in his career he lived in Paris for a decade, and in 1997 he published a memoir, “Paris in the Fifties.” A nostalgic reporter’s notebook of life among the cafe philosophers, berated musicians and pseudo-revolutionary artistes, it danced with digressions about taxes, restaurants, the guillotine, Hemingway, Charles de Gaulle and the Devil’s Island penal colony.

In its range, learning and appetite for fun, Bernard Kalb, the former CBS reporter and Mr. Karnow’s friend since Vietnam, told The Associated Press in 2009, the memoir was vintage Karnow. “Stanley has a great line about how being a journalist is like being an adolescent all your life,” he said.

Stanley Karnow was born in Brooklyn on Feb. 4, 1925, the son of Harry and Henriette Koeppel Karnow. He grew up in a city with more than a dozen daily newspapers and decided early that he wanted to become a reporter. He served in the Army Air Forces in World War II. After graduating from Harvard with a bachelor’s degree in 1947, he sailed for France, intending to spend the summer. He stayed for a decade.
