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.”

Rules to simplifying life come up short

Los Angeles-area author Matthew E. May has hit upon an attractive theme in his recent book, "The Law of Subtraction: 6 Simple Rules for Winning in the Age of Excess Everything" published by McGraw-Hill.

Who does not yearn for a guide to simplifying, synthesizing and subtracting some of the clutter, overload and demands of the "Age of Excess Everything"?

He has also cleverly subtracted from his own workload by inviting others, mostly authors and consultants like him, to contribute about a third of the material for his six laws for doing more with less in the form of summaries of their views.

Mind you, it took fellow author Daniel Pink to point out the appeal of the subject. "Subtraction is your meme. It's out there; it's growing," he told May just before he took the stage at a corporate conference, urging him to "own" it. "Best. Advice. Ever," writes May.

This exchange is itself a little guide to what the book is like. Not only is it full of people talking in a slightly artificial, visionary way about common sense objectives, it is also filled with contradictions. "Subtraction is growing" is only the first.

The book does contain good examples of the less-is-more theme, some well-known, some less so. May's opener (illustrating Law No. 1: "What isn't there can often trump what is") is the FedEx logo, featuring an arrow created by the blank space between the E and X. Lindon Leader, its designer, explains how he "didn't overplay it, didn't mention it" when pitching the idea. (He makes up for that here.)

May, who lives in Westlake Village, also provides a brief history of how Lockheed Corp. put a team of design engineers in a circus tent next to a foul-smelling plastics factory to design a jet fighter: the secret Skunk Works became a byword for how to foster innovation. (Law No. 5: "Break is the important part of breakthrough.")

He cites J.K. Rowling, who was inspired for the idea for Harry Potter on a long, boring train journey, in support of Law No. 6. ("Doing something isn't always better than doing nothing.").

My favorite came from contributor Bob Harrison, a retired police chief, who introduced an "unplan" to withdraw officers directing traffic after a July 4 fireworks display and discovered everyone got home more quickly. (Law No. 2: "The simplest rules create the most effective experience.")

But I find every subtractive success story has an additive counterweight, some of which are explicit in May's examples.

It is true that "creativity thrives under intelligent constraints" (Law No. 4), but Michelangelo — ordered to work on a fresco for the Sistine Chapel, not a sculpture, his preferred medium — then "expanded the job's scope," covering the walls as well as the ceiling.

Steve Jobs was a great simplifier, who "handed control to us" as users of Apple devices. But he was also a control freak when it came to designing the same artifacts, supervising fine detail, adding features and forcing his team to work all hours, rather than giving them time for "purposeful daydreaming," as May advocates elsewhere in his book.

"The Artist," the silent, black-and-white film that provides May with the book's coda, was a worthy Oscar winner — but so was 2008's "Slumdog Millionaire," with its cast of thousands and Bollywood-style excess.

May does not avoid these contradictions, but he does not really address them, either. He prefers to list examples of his six laws rather than explore how employers or their staff could reconcile the daily conflict between constraints and freedom, perspiration and inspiration.

In the interests of "owning" his Zen-inspired meme, May subtracts these complexities. Instead he offers tips, such as his invitation to take "long, languid showers" — No. 8 on a list of ways to relax the mind. This point "needs no explanation," May writes, "which is good, because I could find no research on the subject."

For most people at most companies, where the pressure to add customers, revenue and value is intense, it is as difficult to "subtract" as it is for most grown-ups to follow the advice of one of the book's contributors and live out of a suitcase in a near-empty apartment.

It is a pity, given the need to simplify many business processes, that May adds so little to the sum of knowledge about how to do it.

Hill is the management editor of the Financial Times of London, in which this review first appeared.

L.A. mayoral candidates sound off on pot dispensaries

As Los Angeles voters face the possibility of as many as three medical marijuana initiatives on the May ballot, several mayoral candidates have begun to outline their own plans to deal with the proliferation of pot dispensaries — an issue that has ensnared the City Council in countless legal tangles.

At a mayoral forum sponsored by the League of Women Voters last week, four of the five leading candidates argued for paring back the hundreds of pot dispensaries around the city. But Councilman Eric Garcetti said his first goal would be to persuade the federal government to reclassify marijuana as a medicine: "I will advocate that as mayor," he said.

Garcetti, who presided over many of the battles on the issue as council president from 2006 to 2012, said he would also urge state lawmakers to set regulations governing the distribution of medical marijuana.

"The courts say wildly different things because there has not been clear guidance from the state or federal level," he said. At the city level, Garcetti said, he would try to "keep access" while limiting the number of dispensaries. "You charge a fee so you have an enforcement mechanism, and where possible collect taxes" — steps that, he said, would free up law enforcement officers to focus on more serious crime.

City Controller Wendy Greuel called for "compassion" but said her emphasis would be on tightening regulations on the locations of pot shops in the city.

"I think when people voted in the state of California to allow medical marijuana, they thought they would go to their local CVS pharmacy and get it. They didn't think about the impact it would have on neighborhoods," said Greuel, who is targeting many of the more conservative San Fernando Valley voters. "The bottom line is we have a right to regulate where marijuana clinics are in the city of Los Angeles…. The public is demanding that the government actually do their job."

After the forum, aides to Greuel told The Times she also would support classifying marijuana as a medicine at the federal level.

The city has struggled for years to regulate the placement of pot shops. A loophole in the city's 2007 moratorium allowed hundreds of additional shops to open. The council's efforts to limit the proliferation led to more than 100 lawsuits against the city. In response to complaints from neighborhood activists, the council enacted a ban on storefront marijuana sales last July. But it retreated in October, repealing the ban after a well-organized coalition of marijuana activists mounted an effort to overturn it at the ballot box.

Kevin James, a former federal prosecutor and the sole Republican among the major contenders, said the confusion and legal wrangling illustrated the dysfunction of the council.

"More pot clinics than Starbucks? Unbelievable," James said at Thursday night's forum. "Only this City Council could put a moratorium on 180 or so pot clinics — and it skyrockets to over 1,000."

The five mayoral candidates were pressed to say how many dispensaries should be allowed across the city. James said he favored about 10 in each of the 15 council districts. Garcetti said the original number of dispensaries — approximately 100 — was "about right."

Greuel and Councilwoman Jan Perry said they were hesitant to name an exact number, with Perry adding that she would take her policy cues from the voters in May.

Candidate Emanuel Pleitez, a technology executive who read from notes throughout the forum, argued that "politicians shouldn't be in the business of setting numbers" and should "let the market decide."

Last week the City Council advanced a measure for the May ballot that would permit only the dispensaries that opened before the moratorium to operate; the measure would also raise taxes on marijuana sales. Garcetti backed the request by Councilman Paul Koretz and Council President Herb Wesson asking the city attorney to draw up language for a ballot measure. Perry was absent for the vote.

Two additional — and competing — medical marijuana initiatives have qualified for the May ballot.

One, which is largely backed by dispensaries that opened after the moratorium, would allow many pot shops to remain open, but it would set new requirements for their operations — such as limited hours and maintaining a certain distance from schools. It would raise taxes on medical marijuana by 20% to pay for city enforcement.

The other was created by a coalition of medical marijuana advocates and the United Food and Commercial Workers union, which began organizing dispensary workers last year. Like the City Council-sponsored proposal, it would allow only pot dispensaries that opened before 2007 to operate. Koretz and Wesson have criticized the measure for not mandating that the shops be located farther away from schools, churches and parks.

Some advocates for the union-backed measure now say they probably will support the council's proposal because it too would allow older dispensaries to remain open and has a better chance of passing.

Google reportedly ‘actively exploring’ the smartwatch market

In October, Google (GOOG) was granted a patent for a smartwatch with a flip-up display, however it was assumed that the concept, like most patents, would never move beyond the drawing board. A new report from Business Insider claims that the company is now “actively exploring” the idea of producing its own smartwatch and is even looking into ways it could market such a device. Information is slim and it is unclear what size the device would be or if it would even run the company’s Android operating system. Business Insider cautioned that the project is still in a “very early stage” and “it remains to be seen if Google will actually end up bringing a smart watch to market.” As the Pebble has shown, however, there is clearly a market for smartwatches.

'Fruitvale,' 'Blood Brother' win Sundance Awards

PARK CITY, Utah (AP) — The dramatic film "Fruitvale" and the documentary "Blood Brother" won over audiences and Sundance Film Festival judges.

Both American films won audience awards and grand jury prizes Saturday at the Sundance Awards.

"Fruitvale" tells the true story of Oscar Grant, who was 22 years old when he was shot and killed in a public transit station in Oakland, Calif. Twenty-six-year-old first-time filmmaker Ryan Coogler wrote and directed the dramatic narrative.

"Blood Brother" follows a young American, Rocky, who moved to India to work with orphans infected with HIV.

The Cambodian film "A River Changes Course" won the grand jury prize for international documentary, and a narrative film from South Korea, "Jiseul," claimed the grand jury prize for dramatic world cinema.

Well: Ask Well: Squats for Aging Knees

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

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

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

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

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

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

Hackers take over sentencing commission website

The hacker-activist group Anonymous says it hijacked the website of the U.S. Sentencing Commission to avenge the death of Aaron Swartz, an Internet activist who committed suicide. The FBI is investigating.

The website of the commission, an independent agency of the judicial branch, was taken over early Saturday and replaced with a message warning that when Swartz killed himself two weeks ago “a line was crossed.”

The hackers say they've infiltrated several government computer systems and copied secret information that they now threaten to make public.

Family and friends of Swartz, who helped create Reddit and RSS, say he killed himself after he was hounded by federal prosecutors. Officials say he helped post millions of court documents for free online and that he illegally downloaded millions of academic articles from an online clearinghouse.

The FBI's Richard McFeely, executive assistant director of the Criminal, Cyber, Response, and Services Branch, said in a statement that “we were aware as soon as it happened and are handling it as a criminal investigation. We are always concerned when someone illegally accesses another person's or government agency's network.”

Bell's city clerk is first to testify in corruption case

More than two years after the Bell corruption case erupted, the prosecution called its first witness Friday in an effort to show that the leaders of the small, working-class city became some of the highest-paid city politicians in California by serving on boards that sometimes met just so they could approve further pay hikes.

Rebecca Valdez, Bell's city clerk who has been granted immunity in exchange for her testimony, testified that it was her job to take notes at council meetings, including marking the start and end time of the various boards on which council members served, such as the Solid Waste and Recycling Authority.

"Were there City Council meetings where only some of the authorities met?" Deputy Dist. Atty. Edward Miller asked.

"Yes," Valdez said.

"Were there City Council meetings where none of the authorities met?"

"Yes."

Valdez testified that when she was promoted to city clerk, the council would adjourn after each board met, but that in 2008 it changed so that there were no longer any distinct breaks between the meetings. During a 2011 preliminary hearing, Valdez said she had no idea what the purpose was of some of the boards and commissions.

The city clerk is considered a key prosecution witness in its effort to convict six former Bell council members of misappropriation of public funds by taking huge salaries to serve on board and commissions that rarely met and did little, if any, work.

Miller spent most of the day asking Valdez to verify dozens of documents, including a series of resolutions that showed that all of the defendants at one time had been appointed — not elected — to the council. Valdez herself was appointed city clerk in 2004.

Valdez also verified salary documents for former council members. One listed former Councilwoman Teresa Jacobo's monthly salary as $7,666. Another showed an increase that bumped her salary to $8,083 a month.

In contrast, he then showed the most recent contract for Lorenzo Velez, who was on the council when the salary scandal broke. Velez, the lone council member not charged in the case, was appointed to the council in 2009 and given a salary of only $673.

"Did you prepare this document?" Miller asked Valdez.

"Yes," she said.

"And did somebody give you instructions on how to prepare it?"

"Yes."

"Who was that?"

"The then-City Manager Robert Rizzo."

"Is the city manager an elected official?"

"No."

"How does he get the job?"

Apple’s China dilemma: market share or cachet?

HONG KONG (Reuters) – Apple Inc’s third straight disappointing quarter signals an urgent need for the global technology leader to drum up new revenue – and China may provide the answer.

Now more than ever, analysts say, Apple needs to get it right in the world’s most populous country, where it ranks only sixth in annual smartphone sales and Samsung Electronics remains the runaway leader.

Apple’s best plan of attack remains securing a deal with the country’s top mobile carrier by far, China Mobile Ltd. It also needs to push the development of more localized apps and extend installment financing to bring its pricey smartphones within the reach of an urban populace with an average annual income of just $ 3,500.

But it should resist the temptation to just put out a cheaper iPhone, some analysts say. Introducing a long-rumored lower-cost version of the gadget could backfire by diluting Apple’s premium brand – one of its most valuable assets.

“If you think of Apple, it’s like a bright star in the galaxy, shining so brightly and everyone is looking at it. But it might have dimmed a bit as other stars such as Samsung have popped up,” said TZ Wong, an analyst at research firm IDC.

“I don’t think it’s in Apple’s interest to further dim its star power by stepping into the low-end segment.”

With Apple’s product pipeline guarded with the same zeal accorded state secrets, some analysts are focusing instead on what the world’s largest technology company needs to do to finally become a major player in the world’s No. 2 economy.

While iPhone sales leapt 60 percent last quarter, investors worry that, in the longer term, the company may be pricing itself out of a golden opportunity while Samsung and local rivals from Huawei Technologies Co Ltd to ZTE blanket the market with cheaper phones that rival the iPhone in quality and usability.

A deal with China Mobile, the world’s largest mobile phone carrier with more than 700 million users, will prove instrumental but analysts say that may not happen until the issuance of 4G wireless licenses, which could take place later this year or even in 2014.

“The competitive landscape has definitely cranked up a few notches from a year ago. So there is more urgency for Apple to explore its ways to grow,” IDC’s Wong said.

CEO Tim Cook has made it no secret that China is an area of intense focus for the iPad and iPhone maker, especially given the still-low penetration across the country of smartphones and tablets. Apple has said it will continue to expand its retail network there, and in January, Cook flew to Beijing for at least the second time in a year, to meet with pivotal carrier China Mobile.

A STAR IS DIMMED

On Wednesday, Apple missed revenue forecasts for the third straight quarter after iPhone sales came in below expectations, fanning fears that its dominance of consumer electronics is slipping.

Apple’s revenue in China, including neighboring Hong Kong and Taiwan, totaled $ 7.3 billion in the December quarter, up 60 percent from a year earlier.

But there are signs that Apple’s vaunted cachet in the world’s most populous nation is waning.

Recent product launches for the mini-iPad and the iPhone 5 have drawn a relatively subdued response from Chinese consumers, in stark contrast to the fist-fights and egg-hurling at its Beijing store a year ago when sales of the iPhone 4S were delayed.

Since the iPhone 5 went on sale in mid-December, transactions have fallen by half, according to the Taobao Index, the consumer research data website of Internet giant Alibaba Group.

The iPhone is also losing out as consumers opt for bigger screens to watch Chinese soap operas while travelling on trains, or affordable smartphones in the sub-1,000 yuan ($ 160) category made by local vendors.

“When I started using a bigger screen, there was no turning back for me. Small screens don’t work anymore,” said a business executive surnamed Wen, as he swiped the screen on his Samsung Galaxy Note during lunch in Beijing.

Around half of the more than 60 million smartphones shipped in China in the third quarter last year had screens that were bigger than 4 inches, based on IDC’s latest figures. The iPhone 5 comes with a 4-inch screen, while the Galaxy Note II’s screen is 5.5 inches.

Also, local vendors such as Coolpad smartphone maker Yulong Computer Telecommunication Scientific (Shenzhen) Co Ltd, which offers cheaper alternatives, and Meizu Technology Co Ltd, known for its minimalist designs, have seen its legion of fans grow.

Price is a key factor, especially in the Chinese market where around 80 percent of the more than one billion mobile phone users are still on 2G networks.

On the online Taobao website, Coolpads and low-end models made by Huawei Technologies Co Ltd and ZTE Corp are selling at below 1,000 yuan, a sweet spot for many consumers switching from basic phones to smartphones.

Apple has moved to address that, partnering with China Merchants Bank to offer financing and installment options so that buyers can pay with the bank’s credit card when they shop online, media reports said.

Finally, expanding the number of applications customized for China will help grow Apple’s market share but that might need tighter collaboration with Chinese companies, such as Baidu Inc and Tencent Holdings Ltd.

“Consumers will definitely welcome closer cooperation between Apple and Chinese tech firms to customize the iPhone for the use of apps such as Tencent’s WeChat,” said Frederick Wong, executive director of Avant Capital Management (Hong Kong) Ltd, a fund that invests in Apple-related options.

Dr. Phil to interview alleged girlfriend hoaxer

NEW YORK (AP) — Dr. Phil McGraw has booked the first on-camera interview with the man who allegedly concocted the girlfriend hoax that ensnared Notre Dame football star Manti Te'o.

A "Dr. Phil Show" spokesperson confirmed on Friday the interview with Ronaiah Tuiasosopo (roh-NY-ah too-ee-AH'-so-SO'-poh), the man accused of creating an online persona of a nonexistent woman who Te'o said he fell for without ever meeting face-to-face.

The ruse was uncovered last week by Deadspin.com, which reported that Tuiasosopo created the woman, named Lennay Kekua, who then supposedly died last September.

No further details of the "Dr. Phil" interview, including its airdate, were announced.

This interview follows the first on-camera interview with Te'o conducted this week by Katie Couric.
