Israel, Hamas keep up attacks as talks continue in Egypt

GAZA CITY — As negotiators worked on a tenuous cease-fire deal, Israel and Hamas pounded each other for a sixth day and anger rose in the Gaza Strip over the increasing number of casualties.

Hopes for a truce grew Monday night when Israeli Prime Minister Benjamin Netanyahu convened Cabinet members to discuss the details of what was said to be a multiphase, multiyear cease-fire agreement.

Officials in Egypt, where the talks were underway, expressed cautious optimism. Arab League leaders and United Nations Secretary-General Ban Ki-moon, who was visiting the region, were trying to help negotiate a deal. The White House said President Obama, who is visiting Asia, called Netanyahu and Egyptian President Mohamed Morsi on Monday.

Israel is seeking assurances from Egypt that Hamas will halt rocket fire into Israel and not be allowed to rebuild the weapon caches that Israel has destroyed in recent days. Hamas, which rules the Gaza Strip, wants an end to the land and sea blockade that has crippled its economy, and to targeted killings of its leaders by Israel.

Any sort of agreement must overcome huge obstacles. Israel views Hamas as a terrorist organization and the Islamist militant group refuses to recognize Israel's right to exist.

Even if the two don't alter those stances, any internationally endorsed truce would usher in a new phase in their relationship. Previously Israel and Hamas have refused direct negotiations, occasionally reaching informal agreements brokered through intermediaries, such as last year's deal to release captured Israeli soldier Gilad Shalit.

There are sizable risks for both sides, but also opportunities, said Doron Avital, a lawmaker with Israel's centrist Kadima party and a former commander of an elite military unit.

Hamas would win some of the international legitimacy it craves, but it would also need to moderate its behavior, just as the Palestine Liberation Organization did after signing the Oslo peace accords in 1993.

"It might elevate the status of Hamas, but that will also mean that Hamas will have to play realpolitik," Avital said. "It can't stay a terrorist organization forever. There's an interesting potential here."

Heated comments by Hamas political chief Khaled Meshaal during a Cairo news conference Monday underscored the level of animosity. He called Netanyahu a "child killer" and "murderer."

"It is Netanyahu who asked for a truce," Meshaal said. "Gazans don't even want a truce."

For Israel, besides gaining an end to rocket attacks from Gaza, a deal might start the process of encouraging Hamas to become more moderate. And if Egypt guarantees an agreement, it would be directly invested in keeping Hamas unarmed.

With no cease-fire in place, Israel has massed soldiers and armor along the Gaza border in preparation for a possible invasion. But ground fighting would almost certainly lead to more Israeli and Palestinian casualties, and voices on both sides have cautioned against it.

Some said the negotiations may have led to an uptick in violence in recent days, as each side attempts to intimidate the other before a truce is called.

Palestinian casualties were relatively low in the first days of the conflict, but have increased as Israel's air campaign hit targets in more populated areas. On Monday, Israel attacked the Sharouk communications building in Gaza City where it said four senior members of the Islamic Jihad militant group were meeting.

Among the dead was Ramez Harb, a Palestinian journalist. Israel said he was a legitimate target because he served in the information department of Islamic Jihad.

Hamas' Health Ministry said 107 people had been killed in Gaza, including more than two dozen children. At least 850 people had been wounded.

Three Israelis have died in the barrage of rockets from Gaza and a dozen have been wounded, including three on Monday. An additional 135 rockets were fired Monday, pushing the total over the last week to more than 1,000. Hamas has fired rockets at Tel Aviv and Jerusalem for the first time.

The White House said Obama, in his conversation with Morsi, emphasized that the rocket fire into Israel must end.

In a somber sign of the climbing death toll, hundreds of Gazans crowded around the Shifa Hospital morgue Monday morning in a familiar ritual: collecting the bodies of loved ones.

Election, Storm and Shaky Economy Affect Holiday Shopping

Many retailers have more than the usual riding on sales beginning this Thanksgiving weekend.

The presidential election pushed holiday shopping later than usual because some toy and game makers held off on their big introductions for maximum attention. The aftereffects of Hurricane Sandy have included logistics problems and merchandise delivery delays. And some retailers, trying to keep inventory lean during uncertain economic times, have given themselves little room for error: shipments of holiday toys, for instance, are down 13 percent this year, to the lowest level since 2007, according to the global trade research firm Panjiva.

All of that makes for a particularly strange holiday season, retailers and analysts say.

“The election sucks all of the oxygen out of the room in terms of attention,” said Eric Hirshberg, the chief executive of Activision Publishing, the video game company. “A lot of the best media inventory goes to the candidates. It gets more expensive because there’s this premium demand from the candidates.”

Hasbro is adding more shades of its Furby toy through the end of the year, and Mattel last week introduced a new Monster High video game. Last year, Activision introduced its big Call of Duty release in early November. This year, though, it did not release Call of Duty: Black Ops II until Nov. 13.

“We were also worried that if we released Call of Duty before the election, no one would show up to vote,” Mr. Hirshberg said. (He was speaking facetiously, but given that the game’s retail sales were more than $500 million in the first 24 hours after it made its debut, he may have a point.)

And while retailers were expecting the election to delay some shopping, they were not expecting a storm. RetailNext, which tracks shopper traffic, said that store visits and sales in the Northeast were down about 25 percent during the storm and afterward.

Major retailers have said the election and Hurricane Sandy affected sales. Saks and Target said the beginning of November was choppy, and Macy’s said that the storm seemed to have pushed sales later into the season.

“Some of it is lost, most is postponed,” Karen M. Hoguet, Macy’s chief financial officer, said of demand. “It’s a question of timing.” And Kohl’s chief executive, Kevin Mansell, said the company typically experienced sales slowdowns pre-election and postelection, “and then the business kind of accelerates.”

The late introductions and delayed shopping put toy companies, in particular, in a difficult position: they were under pressure to make hit toys, largely via preorders and layaway, months before people would actually be buying them. Retailers and toy companies started trying to gauge demand early, looking for preliminary data on which items were unpopular and which ones were stars.

Walmart started layaway a month earlier this year versus last year, and Toys “R” Us also started holiday layaway earlier, giving the stores a jump on things. Amazon and other e-commerce sites are promoting tools like preorders, wish lists and gift registries — anything that can give them a sense of what people will buy as the Christmas season churns on.

Preorders are “an important tool to gauge customer demand, and get some feedback from our customers earlier in the process,” said John Alteio, director of toys and games for Amazon. Product introductions later in the year “can be challenging in the toy industry, so we have to draw some comparisons when we can and make the best estimate.”

Paul Solomon, co-chief executive of Moose Toys, which makes Micro Chargers and The Trash Pack, said preorders and layaway were becoming increasingly important. “It’s giving us a good read, early, as to how things are performing, and it’s even more crucial now to make a lot of noise about the brand earlier than in previous years,” he said.

“Preorders are kind of a cottage industry for games like Call of Duty,” Mr. Hirshberg, the Activision chief, said. The company began promoting the game in March, when it ran spots during the NBA playoffs.

In May, it released an ad featuring Oliver North, the national security aide at the heart of the Iran-contra affair and a consultant on the game, talking about the future of warfare. It accepted preorders starting in May. Through the summer, Activision revealed different facets of the game at various conferences, and this month it began running international television, outdoor, digital and mobile ads.

“There’s not a clean math equation that says this many preorders equals this many sales, but it’s confidence-building for us in terms of orders, in terms of production,” Mr. Hirshberg said.

John Barbour, the chief executive of LeapFrog, learned the value of early promotion after last year, when the children’s tablet LeapPad1 became a surprise hit. “It was very hard for me to gauge how successful it would be. Everyone took their best shots,” he said. By November and December, the LeapPad was selling out, and Mr. Barbour had to pay a premium to source tablet screens, and paid for airplanes to fly in extra inventory.

This year, he focused on early promotions that would translate into preorders and layaway, so toy retailers could accurately adjust their orders in time for the holidays. A good response early on means not just bigger orders from retailers, he said, but also more promotional support and more shelf space: it becomes a self-fulfilling prophecy.

“For retailers, it’s phenomenal. It brings demand forward, and they get a better read on what they’re going to need,” he said. When the LeapPad2 became available for preorders in August, it sold as much in two days of preorders as it did in its first week on sale last year, Mr. Barbour said.

He is being careful not to get too jubilant, though. “The penalties for having too much inventory are greater than the penalties for being a little bit short,” he said.

Still, some brands were ignoring the strange events of this holiday season and proceeding as usual. Stephen Bebis, the chief executive of Brookstone, said some products were becoming available in the final months of the year, but that was because of production delays, not strategy.

“People are still going to have to buy gifts for Christmas no matter who’s the president,” he said.

Mitt Romney a Twihard? Candidate and Wife Take in “Twilight” Finale

LOS ANGELES (TheWrap.com) – He may have missed out on becoming leader of the free world when he lost the election to President Obama, but Mitt Romney is keeping busy – with the romantic vampires and werewolves of “Twilight.”

Saturday night, he was spotted with his wife Ann heading into a showing of “Twilight Saga: Breaking Dawn – Part 2″ at a cineplex in Del Mar, Calif., by TMZ. After the movie, they and two young men went to a nearby pizza place, where they reportedly spoke and posed for pictures with patrons.

The Saturday night out for the Romneys was in contrast to the recent movie-viewing by the man who beat him in the election. President Obama last week viewed Oscar hopeful “Lincoln” in a special White House screening with several of the cast members and filmmakers.

There was no word on whether Romney or his wife aligned with Team Edward or Team Jacob.

Global Update: Meningitis Vaccine Gets Longer Window Without Refrigeration

In what may prove to be a major advance for Africa’s “meningitis belt,” regulatory authorities have decided that a new meningitis vaccine could be stored without refrigeration for up to four days.

The announcement was made last week at a conference in Atlanta of the American Society of Tropical Medicine and Hygiene. While a few days may seem trivial, the hardest part of protecting poor countries is often keeping a vaccine cold while moving it from electrified cities to villages with no power. In antipolio drives, for example, the freezers, generators and fuel needed to make ice for the shoulder bags of vaccinators can cost more than the vaccine.

The new vaccine, MenAfriVac, made in India for 50 cents a dose, was introduced in 2010. In bad years, epidemics during the hot harmattan winds have killed as many as 25,000 Africans and disabled 50,000 more. In Chad this year, vaccination drove down cases to near zero in districts where it was used, while others nearby had serious outbreaks.

Experts decided that the vaccine is safe for four days as long as it stays below 104 degrees.

While temperatures get higher than that in Africa, said Dr. Godwin Enwere, medical director for the Meningitis Vaccine Project, teams normally get the vaccine out of coolers at dawn, drive to villages and finish before the day heats up. Other experts said it should be kept in the shade and monitored with colored paper “dots” that darken after hours in the heat.

President Obama arrives in Myanmar after Thailand visit

Yangon, Myanmar — President Obama on Monday became the first U.S. president to visit Myanmar, a once-secretive nation emerging from decades of authoritarian rule.

Obama is expected to urge the Southeast Asian country's government to stay the course toward democratic reforms.

The White House has billed his visit as a celebration of the recent shift by the government of President Thein Sein, symbolized most publicly by the release of dissident Aung San Suu Kyi in 2010 after years of house arrest.

But the visit has also met with criticism from human rights advocates who argue that the accolades are premature and the presidential visit too big a reward for Myanmar's government. Hundreds of political prisoners remain jailed and an ethnic conflict involving a minority group has erupted in recent violence.

Obama administration officials released excerpts of a speech Obama plans to give at Yangon University.

“The flickers of progress that we have seen must not be extinguished — they must become a shining North Star for all this nation’s people,” the speech says.

The remarks include an indirect reference to the plight of the Rohingya, a Muslim minority not granted citizenship. Only Myanmar can define its citizens, but Obama's speech holds up the U.S. as a model.

“I say this because my own country, and my own life, have taught me this,” Obama says in the excerpts. “We have tasted the bitterness of civil war and segregation, but our history shows us that hatred in the human heart can recede, and the lines between races and tribe fade away.”

Obama's six-hour visit to Myanmar, also known as Burma, was expected to include meetings with Thein Sein and Suu Kyi.

Obama planned to praise the iconic dissident, now a member of parliament and leader of the opposition party, for her "fierce dignity."

“She proved that no human being can truly be imprisoned if hope burns in your heart,” he says, according to the excerpts.

Obama planned to highlight the reforms — recognition of Suu Kyi's party, release of some political prisoners, a ban on forced labor and a series of cease-fires that halted ethnic violence in some areas.

Obama suggested that his policies toward Myanmar, which opened diplomatic engagement after years of being cut off from the U.S., were at least partly responsible for the changes. And he sought to use Myanmar as a validation of his engagement strategy elsewhere.

“When I took office as president, I sent a message to those governments who ruled by fear: ‘We will extend a hand if you are willing to unclench your fist,’” the excerpts say. “So today, I have come to keep my promise, and extend the hand of friendship. America now has an ambassador in Rangoon, sanctions have been eased, and we will help rebuild an economy that can offer opportunity for its people, and serve as an engine of growth for the world."

Myanmar is rich in rubber, timber and other potential exports. It also stands to play a key role in Obama's effort to keep China's influence in the region in check.

The visit to Myanmar is part of a three-day tour of Thailand, Myanmar and Cambodia, a trip aimed at drawing attention to Obama's so-called pivot to Asia.

China and U.S. Plan to Replace Trade Negotiators

BEIJING — The rare congruity of the political calendars in the United States and China, with both countries choosing leaders this month, is about to produce an equally rare replacement of most of each side’s senior trade negotiators, with unpredictable results for bilateral economic relations.

One of the few surprises in the carefully scripted Communist Party Congress that ended on Wednesday was that Commerce Minister Chen Deming lost his seat when delegates chose the members of the party’s Central Committee for the next five years.

Under party rules, that means he will have to step down as minister at the National People’s Congress in March. His demotion also meant that he was ineligible to join the Politburo last Thursday and become one of the four vice prime ministers, as some analysts had expected.

Some Chinese analysts say that the direction of the country’s international economic policy is clear and consistent, and that changing the individuals responsible for carrying out that policy will not make much difference.

“The fundamental policy on international trade is adherence to opening and reform,” said He Weiwen, the co-director of the China-U.S./E.U. Study Center at the China Association of International Trade in Beijing. “It will certainly continue and develop to a new height, including China’s trade policy on the U.S.”

But the significance of Mr. Chen’s departure from the Central Committee, which has 205 members and 171 alternates, has divided Western experts about what it means for China’s policies. He has a reputation as a gentlemanly figure who chooses his words with care and has not indulged in outspoken denunciations of the West during trade disputes, even as the tone of social media in China has become increasingly nationalistic on economic policy.

Mr. Chen’s failure to win broad support from the party delegates “does not bode well for future trade relations, and shows that China is pushed by populism,” warned one Western expert who insisted on anonymity because of China’s sensitivity about discussions of personnel changes.

But others cautioned that Mr. Chen had been quick to retaliate for American and European trade actions instead of seeking to negotiate solutions, so his presence at the Commerce Ministry may not have acted as much of a brake on China’s willingness to confront its trading partners.

Most recently, Mr. Chen had started a series of trade actions against imports of the main raw material for solar panels, polysilicon, to retaliate for the stiff American tariffs on Chinese solar panels and European consideration of similar tariffs.

Mr. Chen had been criticized within China’s bureaucracy for falling short on all three of China’s top trade priorities with the European Union: ending the European embargo on arms exports to China, winning “market economy” status from the European Union to discourage antidumping cases against Chinese exports, and discouraging European officials against starting a trade case over solar panels.

According to the state news media, there were only 9.3 percent more candidates for the Central Committee than seats available.

The Chinese government did not release the names of the losing candidates, and it is possible that Mr. Chen’s name was not on the final ballot; he is 63 and approaching retirement. But several people said they were under the impression that Mr. Chen had failed to win.

Mr. Chen’s mercurial predecessor as commerce minister, Bo Xilai, did join the Politburo at the end of his term as minister in 2007, but was purged last spring and is now awaiting trial on various accusations relating to abuse of power.

There are two leading candidates to become the next commerce minister, a job with responsibilities that roughly combine those held separately in the United States by the trade representative and the under secretary of commerce for international trade. One of the contenders is Gao Hucheng, Mr. Chen’s deputy at the Commerce Ministry, and the other is Huang Xingguo, the mayor of Tianjin.

Little is known about their views on trade policy.

Mr. Gao has been seen for years as a successor to Mr. Chen, but Mr. Huang may benefit from the recent promotion of his boss, Zhang Gaoli, who holds the top job in Tianjin as party secretary. Mr. Zhang became one of the seven members of the ruling Politburo Standing Committee on Thursday and is expected to become the executive vice premier overseeing day-to-day economic policy at the National People’s Congress in March.

Two other prominent Chinese officials involved in bilateral relations are leaving their posts. Wang Qishan, the vice prime minister who has led the Chinese economic policy negotiating teams for nearly five years, became a member of the Politburo Standing Committee but was named to lead the Central Commission for Discipline Inspection, which means that he will focus on corruption investigations.

Zhou Xiaochuan, the governor of China’s Central Bank for the past decade, is retiring and was not re-elected to the Central Committee.

In the United States, Secretary of State Hillary Rodham Clinton, Treasury Secretary Timothy F. Geithner and Ron Kirk, the trade representative, are all expected to leave at the end of President Obama’s first term.

This article has been revised to reflect the following correction:

Correction: November 18, 2012

An earlier version of the summary with this article misspelled the name of China’s commerce minister. It is Chen Deming, not Demin.

Movie industry has shed 16,000-plus jobs in L.A. since 2004, study says

LOS ANGELES (TheWrap.com) – The motion-picture industry has lost more than 16,000 jobs in Los Angeles County since the peak year of 2004, according to a new study by the Los Angeles County Economic Development Corp.

And according to the study, “runaway productions” that have moved out of the county due to tax incentives in other areas could be to blame.

The study noted that the motion-picture and video production sector of the entertainment industry – the largest segment of the industry in Los Angeles County – was responsible for 118,200 jobs in the county in 2004, a peak year for the sector. In 2011, by contrast, that number dropped to 102,100 – a 13.6 percent decrease that accounts for 16,100 jobs.

“Arguably, runaway production has had a deleterious effect on industry employment,” the report notes. “New York State alone added 14,100 jobs in this sector over that period, while Georgia added nearly 800 jobs. Meanwhile, Louisiana added over 2,200 jobs since implementing its own tax-credit program in 2002. Other states added jobs in the sector as well.”

The study also points out other factors that could account for the job drain, such as piracy and international competition in such farflung areas as Canada, India and Nigeria, which surpassed Hollywood in 2009 as the second-largest film producer in the world, following India’s Bollywood, according to a report from UNESCO’s Institute for Statistics.

Novelties: Single-Incision Surgery, Via New Robotic Systems

SURGEONS once made incisions large enough to get to a gallbladder or other organs by using conventional tools they held in their own hands. Today, many sit at a computer console instead, guiding robotic arms that enter the patient’s body through small openings not much larger than keyholes.

But even this minimally invasive surgery usually requires multiple incisions: one for the camera system showing the way to the surgeon at the console, and others for each of the robotic arms that do the cutting and stitching.

Now there are robotic systems — one on the market, others in development — that are even less intrusive. They require only a single, small incision through which the robotic arms and camera enter.

This could lead to faster recovery, said Dr. Michael Hsieh, a Stanford professor and a urologist at Lucile Packard Children’s Hospital and Stanford Hospital. “There’s only one wound to heal with this procedure, rather than three,” he said.

Dr. Hsieh, who performs abdominal surgery on small children, uses minimally invasive techniques that typically now require three incisions. His patients generally go home a day or two after surgery, he said, “but I think they would recover more quickly if I could reduce my multiple incisions to just one,” he said. “And there will be less scarring, or even no scarring, if you enter through the navel.”

He will soon have a chance to try out the new method on his patients. Stanford Hospital is buying a system from Intuitive Surgical called Single-Site that requires only a single incision of about one inch. The system, approved by the Food and Drug Administration only for gallbladder removal, is used as an add-on to a basic robotic system from Intuitive, known as the da Vinci Si.

The Si costs $1.3 million to $2.2 million, said Angela Wonson, a spokeswoman for Intuitive, based in Sunnyvale, Calif. The Single-Site can add $60,000 or more to the bill, or far less, depending in part on the equipment that hospitals might already have.

The East Jefferson General Hospital in Metairie, La., has bought a Single-Site system. Seated at a computer there, Dr. Joseph Uddo Jr. can control the instruments, which can enter the body by way of one incision in the navel. Surgical instruments like scissors are at the ends of the robotic arms. “To change a tool, you take out one instrument and load in another,” he said.

ANOTHER surgical robotic system, now in development, enters the body through a remarkably small incision — six-tenths of an inch, or 15 millimeters. The robot was designed by Drs. Dennis Fowler and Peter Allen of Columbia University and Dr. Nabil Simaan of Vanderbilt University. Once inside the body, it unfolds to reveal a camera system and two snakelike arms that perform the surgery. The system has been licensed to Titan Medical in Toronto.

Minimally invasive surgery through a single incision can also be performed with long, thin laparoscopic tools that surgeons wield as they watch a video monitor. But single-incision laparoscopic surgery with hand-held instruments can have problems, said Dr. Adrian Park, chairman of the department of surgery at the Anne Arundel Medical Center in Annapolis, Md., who specializes in minimally invasive gastrointestinal surgery. One difficulty is its ergonomic challenge to doctors, while another is the pressure that the tools place on tissue during single-incision operations.

Robotic systems, by contrast, are likely to ease single-incision surgery, said Jeffrey J. Tomaszewski, a fellow in urologic oncology at the Fox Chase Cancer Center in Philadelphia.

“Robots are an extension and multiplier of our own surgical hands,” Dr. Tomaszewski said. He has done traditional laparoscopic surgery with hand-held instruments, including operations through a single incision. “But you can be working at constrained angles,” he said. “A robot can improve the angle of workability.”

Robotic systems, though, have yet to show that they are always worth the extra money they cost. Such proof will take time, said Allison Okamura, an associate professor of mechanical engineering at Stanford who directs the Collaborative Haptics and Robotics in Medicine Lab. “The jury is still out because of the longevity of the studies that are required,” she said.

Dr. Tomaszewski agreed. “We surgeons love using the robot,” he said. “But the question is, and what we all have to fight hard to do, is to determine for what procedure the robotic approach provides the best benefit.”

Dr. Hsieh says he hopes that single-site robotic systems will someday bring a benefit he’s long dreamed about.

“We may get to the point where we do outpatient, scarless robotic surgery,” he said. “That’s what I’m shooting for.”
