Google draws fire over data sharing on app store

SAN FRANCISCO — When someone buys Sebastian Holst's Mobile Yogi app in the Google Play store, Holst automatically gets something he says he didn't ask for: that person's name, location and email address.

No other app store transmits users' personal information to third parties when they buy digital goods, he said. And he and other mobile app developers say many people are unaware that their personal details are being shared.

"Google is not taking reasonable steps to ensure that this data is used correctly," said Holst, whose apps have 120,000 users.

Google is coming under fire just as regulators in the U.S. and overseas are stepping up their scrutiny of how all the players in the industry — mobile app developers, stores, advertising networks and others — handle consumers' private information. Regulators are pushing for greater transparency of what information is collected by apps and how it's shared.

Google defends its app store's operation, saying it's set up differently from other stores' to let customers interact directly with the app makers.

With Google Play, which launched in October 2008, an app developer sets up an account through the mobile payment system Google Wallet, which makes the developer a merchant in the store. When someone buys his or her app from Google Play, that transaction — and the customer's information — is sent to the developer.

The app developer has to comply with rules about what he or she can do with the information, Google says. Google sees itself more as an intermediary, whereas when consumers buy apps from Apple Inc., iTunes is the merchant, and app developers say they never receive customer information.

"Google Wallet shares the information necessary to process a transaction, which is clearly spelled out in the Google Wallet privacy notice," Google said.

Barry Schwartz, news editor of the Search Engine Land blog and an app developer, said Google's system works better for developers and for customers.

"They are my customers, not Google's and not Apple's customers. They download our products. They call the developer with questions. We provide them the tools and the content," Schwartz wrote in a blog post. "Apple doesn't tell us who our customers are, and when we need that information to verify ownership or to give refunds, we are left with blindfolds on. Google, in my opinion, does it right by making the user who downloads the app our customer."

But Danny Sullivan, founding editor of Search Engine Land, said Google should make it clearer to consumers that their information is being shared with third-party developers.

"I sure had no idea that Google Play did this," Sullivan said.

Nor did Dan Nolan, an Australian app developer. He said he was astonished when he found out that Google was sending him users' personal information. He wrote a blog post Wednesday condemning the practice.

"Under no circumstances should I be able to get the information of the people who are buying my apps unless they opt into it and it's made crystal clear to them that I'm getting this information," Nolan said.

App stores have become the engines of the mobile economy. Apple kicked off the mobile app boom in 2008, but Google is catching up. As of October, Google Play had the same number of apps — 700,000 — as Apple, although Apple's app sales still generate several times the revenue of Google's.

Google is trying to gain an advantage by making it easier for developers to build apps and easier for users to buy them. Apps help fuel the growing popularity of cellphones that run Google's Android software.

But privacy watchdogs say Google is not playing fair with Google Play customers by not making it clear who has access to their personal information.

In a 2011 settlement with the Federal Trade Commission, Google agreed it would ask users before sharing their data with outsiders after the government alleged the company had violated users' privacy with its social network Buzz. The settlement also required the search giant to submit to independent privacy audits every two years for 20 years. Last year Google had to pay $22.5 million to settle charges for bypassing the privacy settings of millions of Apple users. It was the largest penalty ever levied on a company by the FTC.

Google denied that Google Play's handling of personal information violated its agreement with the FTC.

"This is not a violation of the consent decree," it said in a statement.

A commission spokeswoman declined to comment.

Google is not the only company that has drawn criticism for how it shared information with app developers. In 2011, Facebook Inc. agreed to a 20-year privacy settlement with the FTC that required the company to get users' permission before changing the way it treats personal information. The FTC alleged that Facebook engaged in deceptive behavior when it promised that third-party apps would have access only to user information they needed, when in fact many apps had unrestricted access to users' personal data.

"The question is: What constitutes meaningful consent?" said Marc Rotenberg, executive director of the Electronic Privacy Information Center. "The bottom line is that users are not able to control how their data is being gathered and disclosed."

Oscar Pistorius remains in jail facing murder charge

JOHANNESBURG, South Africa -- South African athlete Oscar Pistorius, who made history last year as the first double amputee runner to compete in the Olympics using prosthetic blades, will spend the night in jail Thursday after he was charged with murder in the death of his girlfriend at his house, prosecutors said.

The National Prosecuting Authority said Pistorius would remain in custody until his hearing Friday, when police intend to oppose bail.

Reeva Steenkamp, a 30-year-old model, died after being shot several times in the head and arm in Pistorius’ house in an upscale suburb in Pretoria.

PHOTOS: Pistorius in the London Olympics

Pistorius was ushered from the home by police Thursday morning with a gray hoodie covering his head and obscuring most of his face.

South Africans were in shock about the accusation against Pistorius, who became a hero during his long battle for the right to compete in the Olympics. After a controversy on whether the blades he uses to walk and run gave him an advantage in races, Pistorius was granted the right to compete in the London 2012 Olympic Games.

South Africa has one of the world's highest rates of murder and violent crime, and many South Africans keep guns at home to guard against intruders.

The Afrikaans-language newspaper Beeld suggested that Pistorius mistook his girlfriend for a burglar and killed her accidentally.

However, a police spokeswoman, Brig. Denise Beukes, said police were “surprised” at reports the killing was accidental, adding that that version hadn’t come from police, according to the South African Press Assn.

"I confirm there had been previous incidents of a domestic nature at his place,” said Beukes, adding that police couldn’t comment on the decision to oppose bail.

Beukes said police had interviewed neighbors who heard sounds at Pistorius’ home earlier in the evening, and also at the time the incident reportedly took place.

Pistorius’ father, Henke Pistorius, said his son was sad. But the older Pistorius said he didn’t know the facts.

“I don’t know nothing. It will be extremely obnoxious and rude to speculate,” he said in a radio interview. “If anyone makes a statement, it will have to be Oscar.”

An advertisement for Nike, one of Pistorius’ major sponsors, was removed from his official website Thursday. It had shown the athlete in a green lycra athletic suit and the slogan, “I am the bullet in the chamber."

'Melrose' actress gets 3 years for deadly NJ crash

SOMERVILLE, N.J. (AP) — A former "Melrose Place" actress who was drunk when her SUV plowed into a car and killed a woman was sentenced Thursday to three years in prison, infuriating the victim's relatives, who had hoped for the 10-year maximum.

"What a travesty!" the victim's husband, Fred Seeman, yelled after the sentence was read.

"This is not justice," the victim's 26-year-old son, Ford Seeman, told the judge before he stormed out of the courtroom.

A jury in November convicted Amy Locane-Bovenizer of vehicular homicide in the 2010 death of 60-year-old Helene Seeman in Montgomery Township.

Locane-Bovenizer will be eligible for parole after 2 1/2 years and will be credited the 81 days she has already served. She also had her license suspended for five years and will be on probation for three years after her release. She must pay several thousand dollars in fines.

Locane-Bovenizer, who didn't testify at the trial, appeared in 13 episodes of TV's "Melrose Place" and in movies including "Cry-Baby," ''School Ties" and "Secretary."

Prosecutors say she was driving with a blood-alcohol level nearly three times the legal limit when her SUV slammed into a Mercury Milan driven by Fred Seeman as he was turning into his driveway. Fred Seeman's wife, Helene, was killed, and he was seriously injured.

During the trial, the defense argued that Fred Seeman was making a slow turn, which contributed to the crash. They maintained that it was an accident, not a crime.

The defense also shifted blame to a third motorist who they say distracted the actress by honking at her and chasing her after being rear-ended. They said the chase led Locane-Bovenizer to drive 20 miles over the speed limit on a dark two-lane road.

The judge lowered the maximum sentence citing the hardship on Locane-Bovenizer's two young children. One has a serious medical and mental disability. The defense went into detail about how her sick child was deteriorating physically and psychologically since the actress' incarceration and about how a prolonged sentence would make it worse.

"I'm just glad her little girls will have their mother back soon," Locane-Bovenizer's mother, Helen Locane, said as she walked out of the courtroom.

In an emotionally charged statement, Fred Seeman told the court that the defense contention that his vehicle was turning slowly added "salt on the wound," and he said he was appalled that Locane-Bovenizer took no responsibility for killing his wife.

The actress, in turn, apologized to Seeman's family and said she did take full responsibility.

"I am truly sorry for all of the pain I have caused," she said, struggling to get through her statement, as she looked toward the family that packed one side of the courtroom while her friends and family packed the other. "My own suffering will never go away."

Judge Robert Reed said that he had no sympathy for the actress but that the children should not suffer even more because of her actions.

The Seeman family said after the sentencing that the decision was a "mockery" and only added to the suffering they've endured since the accident.

"What's one more punch in the gut?" Ford Seeman said.

Doctor and Patient: Afraid to Speak Up to Medical Power

The slender, weather-beaten, elderly Polish immigrant had been diagnosed with lung cancer nearly a year earlier and was receiving chemotherapy as part of a clinical trial. I was a surgical consultant, called in to help control the fluid that kept accumulating in his lungs.

During one visit, he motioned for me to come closer. His voice was hoarse from a tumor that spread, and the constant hissing from his humidified oxygen mask meant I had to press my face nearly against his to understand his words.

“This is getting harder, doctor,” he rasped. “I’m not sure I’m up to anymore chemo.”

I was not the only doctor that he confided to. But what I quickly learned was that none of us was eager to broach the topic of stopping treatment with his primary cancer doctor.

That doctor was a rising superstar in the world of oncology, a brilliant physician-researcher who had helped discover treatments for other cancers and who had been recruited to lead our hospital’s then lackluster cancer center. Within a few months of the doctor’s arrival, the once sleepy department began offering a dazzling array of experimental drugs. Calls came in from outside doctors eager to send their patients in for treatment, and every patient who was seen was promptly enrolled in one of more than a dozen well-documented treatment protocols.

But now, no doctors felt comfortable suggesting anything but the most cutting-edge, aggressive treatments.

Even the No. 2 doctor in the cancer center, Robin to the chief’s cancer-battling Batman, was momentarily taken aback when I suggested we reconsider the patient’s chemotherapy plan. “I don’t want to tell him,” he said, eyes widening. He reeled off his chief’s vast accomplishments. “I mean, who am I to tell him what to do?”

We stood for a moment in silence before he pointed his index finger at me. “You tell him,” he said with a smile. “You tell him to consider stopping treatment.”

Memories of this conversation came flooding back last week when I read an essay on the problems posed by hierarchies within the medical profession.

For several decades, medical educators and sociologists have documented the existence of hierarchies and an intense awareness of rank among doctors. The bulk of studies have focused on medical education, a process often likened to military and religious training, with elder patriarchs imposing the hair shirt of shame on acolytes unable to incorporate a profession’s accepted values and behaviors. Aspiring doctors quickly learn whose opinions, experiences and voices count, and it is rarely their own. Ask a group of interns who’ve been on the wards for but a week, and they will quickly raise their hands up to the level of their heads to indicate their teachers’ status and importance, then lower them toward their feet to demonstrate their own.

It turns out that this keen awareness of ranking is not limited to students and interns. Other research has shown that fully trained physicians are acutely aware of a tacit professional hierarchy based on specialties, like primary care versus neurosurgery, or even on diseases different specialists might treat, like hemorrhoids and constipation versus heart attacks and certain cancers.

But while such professional preoccupation with privilege can make for interesting sociological fodder, the real issue, warns the author of a courageous essay published recently in The New England Journal of Medicine, is that such an overly developed sense of hierarchy comes at an unacceptable price: good patient care.

Dr. Ranjana Srivastava, a medical oncologist at the Monash Medical Centre in Melbourne, Australia, recalls a patient she helped to care for who died after an operation. Before the surgery, Dr. Srivastava had been hesitant to voice her concerns, assuming that the patient’s surgeon must be “unequivocally right, unassailable, or simply not worth antagonizing.” When she confesses her earlier uncertainty to the surgeon after the patient’s death, Dr. Srivastava learns that the surgeon had been just as loath to question her expertise and had assumed that her silence before the surgery meant she agreed with his plan to operate.

“Each of us was trying our best to help a patient, but we were also respecting the boundaries and hierarchy imposed by our professional culture,” Dr. Srivastava said. “The tragedy was that the patient died, when speaking up would have made all the difference.”

Compounding the problem is an increasing sense of self-doubt among many doctors. With rapid advances in treatment, there is often no single correct “answer” for a patient’s problem, and doctors, struggling to stay up-to-date in their own particular specialty niches, are more tentative about making suggestions that cross over to other doctors’ “turf.” Even as some clinicians attempt to compensate by organizing multidisciplinary meetings, inviting doctors from all specialties to discuss a patient’s therapeutic options, “there will inevitably be a hierarchy at those meetings of who is speaking,” Dr. Srivastava noted. “And it won’t always be the ones who know the most about the patient who will be taking the lead.”

It is the potentially disastrous repercussions for patients that make this overly developed awareness of rank and boundaries a critical issue in medicine. Recent efforts to raise safety standards and improve patient care have shown that teams are a critical ingredient for success. But simply organizing multidisciplinary lineups of clinicians isn’t enough. What is required are teams that recognize the importance of all voices and encourage active and open debate.

Since their patient’s death, Dr. Srivastava and the surgeon have worked together to discuss patient cases, articulate questions and describe their own uncertainties to each other and in patients’ notes. “We have tried to remain cognizant of the fact that we are susceptible to thinking about hierarchy,” Dr. Srivastava said. “We have tried to remember that sometimes, despite our best intentions, we do not speak up for our patients because we are fearful of the consequences.”

That was certainly true for my lung cancer patient. Like all the other doctors involved in his care, I hesitated to talk to the chief medical oncologist. I questioned my own credentials, my lack of expertise in this particular area of oncology and even my own clinical judgment. When the patient appeared to fare better, requiring less oxygen and joking and laughing more than I had ever seen in the past, I took his improvement to be yet another sign that my attempt to talk about holding back chemotherapy was surely some surgical folly.

But a couple of days later, the humidified oxygen mask came back on. And not long after that, the patient again asked for me to come close.

This time he said: “I’m tired. I want to stop the chemo.”

Just before he died, a little over a week later, he was off all treatment except for what might make him comfortable. He thanked me and the other doctors for our care, but really, we should have thanked him and apologized. Because he had pushed us out of our comfortable, well-delineated professional zones. He had prodded us to talk to one another. And he showed us how to work as a team in order to do, at last, what we should have done weeks earlier.

The myth of deregulation's consumer benefits

Here's a question for you: Is there a single example of consumer prices going down and market competition increasing after deregulation of a U.S. industry?

I'm serious. The phone industry? The cable industry? Regulatory oversight for both was eased — and in some cases eliminated — and look where that's gotten us.

And now look at the airline industry, which witnessed its latest multibillion-dollar deal Thursday with the merger of American Airlines and US Airways, creating the world's largest carrier.

Experts were buzzing after the announcement with dire warnings of higher fares, more crowded planes and fewer options for travelers — and they're probably right.

Once the merger is completed, four airlines — American, United, Delta and Southwest — will control about 75% of the U.S. market.

So I'll ask again, is there one, just one, example of deregulation working in consumers' favor?

Richard H.K. Vietor, a professor of business administration at Harvard Business School, said there have been numerous examples of deregulation bringing prices down for varying amounts of time.

In the case of airlines, he said, we've enjoyed decades of lower fares since the industry was deregulated in 1978.

"That's the good thing," Vietor said. "The bad thing is that, as we've seen, competition erodes and you get back to oligopolies."

The U.S. airline industry now resembles how it looked in the 1930s, he said, with just a handful of carriers controlling most air traffic. As a result, the primary benefit of deregulation — lower fares — could disappear as fewer airlines duke it out for business.

"Consumers used to get meals, free drinks and much better service," Vietor said. "Now you have to pay for your friggin' bags."

Before deregulation, airlines had to ask the Civil Aeronautics Board to sign off on fares and routes. Deregulation allowed carriers to make those decisions for themselves, the hope being that a more market-driven industry would give rise to new competitors and thus push fares lower and improve service.

It's a song we've heard free marketers sing before in defense of all deregulation efforts: Less interference by clumsy old Uncle Sam will unleash the dynamic forces of capitalism and usher in a new era of industrial and consumer paradise (see Rand, Ayn, "Atlas Shrugged").

AT&T's monopoly over phone service ended in 1984 in a government settlement that gave the local phone networks to seven regional operators, known as the Baby Bells. The telecommunications market was deregulated in 1996 in hopes of promoting more competition.

Where are we now? A wave of mergers has resulted in just two companies, AT&T and Verizon, controlling almost the entire U.S. landline market. AT&T, Verizon and Sprint account for about 75% of the wireless market.

On the cable side of things, four companies — Comcast, Time Warner Cable, Charter Communications and Cox Communications — now account for about two-thirds of all U.S. subscribers.

Needless to say, phone and cable rates have risen steadily since the telecom market was deregulated.

Airline fares have been a different story. They've stayed relatively cheap since deregulation, though many travelers might say service hasn't exactly been something to cheer about.

Meanwhile, it's been nothing but turbulence for the airline industry. From 1978 to 2001, nine major carriers and hundreds of smaller ones either went bankrupt or were liquidated. Storied names such as Pan Am, TWA, Eastern and Braniff disappeared.

In recent years, the focus has been on big-ticket consolidation. Delta acquired Northwest. United picked up Continental. And now American and US Airways are tying the knot.

Dorner manhunt: Investigators work to ID charred human remains

After what LAPD Chief Charlie Beck called "a bittersweet night," investigators Wednesday were in the process of identifying the human remains found in the charred cabin where fugitive ex-cop Christopher Dorner was believed to have been holed up after trading gunfire with officers, authorities said.

If the body is identified as Dorner’s, the standoff would end a weeklong manhunt for the ex-LAPD officer and Navy Reserve lieutenant suspected in a string of shootings following his firing by the Los Angeles Police Department several years ago. Four people have died in the case, allegedly at Dorner’s hands.

Beck said he would not consider the manhunt over until the body was identified as Dorner. Police remained on tactical alert and were conducting themselves as if nothing had changed in the case, officials said.

PHOTOS: Manhunt for ex-LAPD officer

The latest burst of gunfire came Tuesday after the suspect, attempting to flee law enforcement officials, fatally shot a San Bernardino County sheriff’s deputy and seriously injured another, officials said. He then barricaded himself in a wooden cabin outside Big Bear, not far from ski resorts in the snow-capped San Bernardino Mountains east of Los Angeles, according to police.

"This could have ended much better, it could have ended worse," said Beck as he drove to the hospital where the injured deputy was located. "I feel for the family of the deputy who lost his life."

The injured deputy is expected to survive but it is anticipated he will need several surgeries. The names of the two deputies have not been released.

TIMELINE: Manhunt for ex-LAPD officer

Just before 5 p.m., authorities smashed the cabin's windows, pumped in tear gas and called for the suspect to surrender, officials said. They got no response. Then, using a demolition vehicle, they tore down the cabin's walls one by one. When they reached the last wall, they heard a gunshot. Then the cabin burst into flames, officials said.

Last week, authorities said they had tracked Dorner to a wooded area near Big Bear Lake. They found his torched gray Nissan Titan with several weapons inside, the said, and the only trace of Dorner was a short trail of footprints in newly fallen snow.

According to a manifesto that officials say Dorner posted on Facebook, he felt the LAPD unjustly fired him several years ago, when a disciplinary panel determined that he lied in accusing his training officer of kicking a mentally ill man during an arrest. Beck has promised to review the case.

DOCUMENT: Read the manifesto

The manifesto vows "unconventional and asymmetrical warfare" against law enforcement officers and their families. "Self-preservation is no longer important to me. I do not fear death as I died long ago," it said.

On Tuesday morning, two maids entered a cabin in the 1200 block of Club View Drive and ran into a man who they said resembled the fugitive, a law enforcement official said. The cabin was not far from where Dorner's singed truck had been found and where police had been holding news conferences about the manhunt.

The man tied up the maids, and he took off in a purple Nissan parked near the cabin, the official said. About 12:20 p.m., one of the maids broke free and called police.

Nearly half an hour later, officers with the California Department of Fish and Wildlife spotted the stolen vehicle and called for backup, authorities said. The suspect turned down a side road in an attempt to elude the officers but crashed the vehicle, police said.

A short time later, authorities said, the suspect carjacked a light-colored pickup truck. Allan Laframboise said the truck belonged to his friend Rick Heltebrake, who works at a nearby Boy Scout camp.

Heltebrake was driving on Glass Road with his Dalmatian, Suni, when a hulking African American man stepped into the road, Laframboise said. Heltebrake stopped. The man told him to get out of the truck.

"Can I take my dog?" Heltebrake asked, according to his friend.

Miss America pageant returns to Atlantic City, NJ

TRENTON, N.J. (AP) — There she is, Miss America, headed back to Atlantic City, N.J.

The Miss America pageant was an Atlantic City staple for decades before it was moved to Las Vegas in 2006.

Gov. Chris Christie's spokesman Michael Drewniak confirmed the news of the pageant's return to Atlantic City on Wednesday night. Lt. Gov. Kim Guadagno (gwah-DAHN'-oh) is scheduled make a formal announcement Thursday on Atlantic City's Boardwalk Hall.

The Miss America pageant started as little more than a bathing suit revue. It broke viewership records in its heyday and bills itself as one of the world's largest scholarship programs for women. But like other pageants, it has struggled to stay relevant as national attitudes regarding women's rights have changed.

Pageant officials haven't responded to an after-hours email seeking comment.

Phys Ed: Getting the Right Dose of Exercise

Phys Ed

Gretchen Reynolds on the science of fitness.

Fitness Tracker

Marathon, half-marathon, 10k and 5K training plans to get you race ready.

A common concern about exercise is that if you don’t do it almost every day, you won’t achieve much health benefit. But a commendable new study suggests otherwise, showing that a fairly leisurely approach to scheduling workouts may actually be more beneficial than working out almost daily.

For the new study, published this month in Exercise & Science in Sports & Medicine, researchers at the University of Alabama at Birmingham gathered 72 older, sedentary women and randomly assigned them to one of three exercise groups.

One group began lifting weights once a week and performing an endurance-style workout, like jogging or bike riding, on another day.

Another group lifted weights twice a week and jogged or rode an exercise bike twice a week.

The final group, as you may have guessed, completed three weight-lifting and three endurance sessions, or six weekly workouts.

The exercise, which was supervised by researchers, was easy at first and meant to elicit changes in both muscles and endurance. Over the course of four months, the intensity and duration gradually increased, until the women were jogging moderately for 40 minutes and lifting weights for about the same amount of time.

The researchers were hoping to find out which number of weekly workouts would be, Goldilocks-like, just right for increasing the women’s fitness and overall weekly energy expenditure.

Some previous studies had suggested that working out only once or twice a week produced few gains in fitness, while exercising vigorously almost every day sometimes led people to become less physically active, over all, than those formally exercising less. Researchers theorized that the more grueling workout schedule caused the central nervous system to respond as if people were overdoing things, sending out physiological signals that, in an unconscious internal reaction, prompted them to feel tired or lethargic and stop moving so much.

To determine if either of these possibilities held true among their volunteers, the researchers in the current study tracked the women’s blood levels of cytokines, a substance related to stress that is thought to be one of the signals the nervous system uses to determine if someone is overdoing things physically. They also measured the women’s changing aerobic capacities, muscle strength, body fat, moods and, using sophisticated calorimetry techniques, energy expenditure over the course of each week.

By the end of the four-month experiment, all of the women had gained endurance and strength and shed body fat, although weight loss was not the point of the study. The scientists had not asked the women to change their eating habits.

There were, remarkably, almost no differences in fitness gains among the groups. The women working out twice a week had become as powerful and aerobically fit as those who had worked out six times a week. There were no discernible differences in cytokine levels among the groups, either.

However, the women exercising four times per week were now expending far more energy, over all, than the women in either of the other two groups. They were burning about 225 additional calories each day, beyond what they expended while exercising, compared to their calorie burning at the start of the experiment.

The twice-a-week exercisers also were using more energy each day than they had been at first, burning almost 100 calories more daily, in addition to the calories used during workouts.

But the women who had been assigned to exercise six times per week were now expending considerably less daily energy than they had been at the experiment’s start, the equivalent of almost 200 fewer calories each day, even though they were exercising so assiduously.

“We think that the women in the twice-a-week and four-times-a-week groups felt more energized and physically capable” after several months of training than they had at the start of the study, says Gary Hunter, a U.A.B. professor who led the experiment. Based on conversations with the women, he says he thinks they began opting for stairs over escalators and walking for pleasure.

The women working out six times a week, though, reacted very differently. “They complained to us that working out six times a week took too much time,” Dr. Hunter says. They did not report feeling fatigued or physically droopy. Their bodies were not producing excessive levels of cytokines, sending invisible messages to the body to slow down.

Rather, they felt pressed for time and reacted, it seems, by making choices like driving instead of walking and impatiently avoiding the stairs.

Despite the cautionary note, those who insist on working out six times per week need not feel discouraged. As long as you consciously monitor your activity level, the findings suggest, you won’t necessarily and unconsciously wind up moving less over all.

But the more fundamental finding of this study, Dr. Hunter says, is that “less may be more,” a message that most likely resonates with far more of us. The women exercising four times a week “had the greatest overall increase in energy expenditure,” he says. But those working out only twice a week “weren’t far behind.”

California housing recovery may gain momentum, experts say

New foreclosures in California fell sharply in January as new state rules for banks took effect, signaling that repossessions may finally settle in at levels not seen since before the housing bust.

The resulting decline in bank-owned properties listed for sale on the market — as well as record numbers of investors prowling for bargains — should give the state's housing recovery momentum this year, experts said.

In the Southland, the new year kicked off with a sharp annual gain in sales, the highest volume for a January in six years. The region's median home price notched a sharp 23.5% gain over the same month last year. And new foreclosure actions plummeted statewide.

"The recovery is for real, that is what I think is happening," said Esmael Adibi, director of Chapman University's A. Gary Anderson Center for Economic Research. "It is being driven by real demand, and fundamentals are favorable."

The price gains reflect a shift in the market away from foreclosures and toward regular sales, reflecting a recovery on solid ground, said Christopher Thornberg, founding principal at Beacon Economics.

"The question is, is it the real deal?'" Thornberg said. "Sure it is. It is driven of course by a very tight market … about as tight as it gets, and ultimately inventory drives prices."

Although prices may be gaining, the healthiest contributors to housing strength — employment gains and consumer confidence — appear to be playing less of a factor than investor activity and low mortgage interest rates. That's cause for some concern, but the housing market still has a long way to go to recover from its peak summer 2007 levels, DataQuick President John Walsh said.

"This fledgling housing recovery has momentum," Walsh said in a statement. "Already, price hikes have caused some to question whether it's sustainable, whether it's a 'bubble.' Let's not forget, though, that we're still climbing out of a deep hole from the housing downturn."

The home price and sales gains came as foreclosure starts in California took a massive tumble last month as new state laws aimed at prohibiting certain aggressive bank repossession practices went into effect. The real estate website ForeclosureRadar.com reported a 60.5% decline in California default notices in January from December.

The number of default notices — the first formal step in the state's foreclosure process — fell 77.7% from December 2011. A total of 4,500 such filings were logged last month — the lowest number of default notices since at least September 2006, when the website's records begin.

The website noted that the foreclosure drop came in January, when a package of tough new laws protecting California homeowners went into effect. Most notably, the Homeowner Bill of Rights bans the practice of "dual tracking," in which a lender seizes a home while the owner is negotiating to lower mortgage payments.

The laws also outlawed so-called robo-signing — the improper or faulty processing of foreclosure documents — and would allow state agencies and private citizens to sue financial institutions, under limited conditions, for economic compensation and for additional civil damages of up to $50,000. Passed last year, the legislative package was sponsored by California Atty. Gen. Kamala D. Harris and written by 10 Democratic lawmakers.

While dramatic, the drop is part of a general decline in foreclosure actions over the last year as banks look toward short sales and loan modifications as alternatives to seizing homes.

"You will see a continued decline in defaults from regulator activity, new laws and from the economy," said Dustin Hobbs, a spokesman for the California Mortgage Bankers Assn. "As long as the economy, and especially the housing market, continues to slowly heal itself, you will see fewer and fewer defaults."

Katherine Porter, a UC Irvine law professor who is monitoring the state's accord with the nation's five largest mortgage servicers over foreclosure abuses, said that it was not clear to her whether the dramatic drop in foreclosures resulted directly from new laws. The decrease could be temporary, she said, as mortgage servicers adjust their foreclosure processing systems.

Madeline Schnapp, director of economic research for ForeclosureRadar, believes the low levels of foreclosures will continue.

"The plethora of anti-foreclosure laws have been very effective in reducing foreclosure activity to what you are seeing today," she said.

Foreclosed homes made up just 15% of the resale market last month, down dramatically from the worst of the crash, when they hit a high of 56.7% in February 2009. Short sales made up an estimated 25.9% of the resale market last month.

Fewer foreclosures will probably lead to more gains in home prices, because foreclosures have been the main supply of cheap housing. But rising prices also will lift more underwater homeowners out of a negative equity position, helping them sell their homes, which could also loosen up some supply.

Buyers paid a median $321,000 last month in Southern California, a reflection of rising prices and a shift in the buying mix from lower-end starter homes to pricier digs.

Sales of homes in the region's move-up market have continued to gain. Sales of homes priced from $300,000 to $800,000 soared 49.6% year-over-year in January, while sales of homes costing more than $500,000 jumped 74% from a year earlier.

Meanwhile, sales of homes costing less than $200,000 fell 23.5% from the previous January, an indication of tight inventory levels in those markets as investors look to snap up houses and rent them out.

Smoke, flame amid 'tactical operation' in Dorner shootout

One deputy has died, another is wounded.

Smoke and flames were visible from the area where fugitive former law enforcement officer Christopher Jordan Dorner was holed up in a Big Bear-area cabin after gun battles with law enforcement officers.

Law enforcement sources said "a tactical operation" was underway at the cabin but did not provide further details.

A tall plume of smoke was rising from the area where the standoff occurred. Hundreds of law enforcement personnel swooped down on the site near Big Bear following the gun battles between Dorner and officers that broke out in the snow-covered mountains where the fugitive had been eluding a massive manhunt since his truck was found burning in the area late last week.

Law enforcement personnel in military-style gear and armed with high-powered weapons were involved in a tense standoff after Dorner took refuge in the cabin Tuesday afternoon. 

One San Bernardino County sheriff's deputy died of his wounds after he and another deputy were wounded in an exchange of gunfire outside the cabin in which hundreds of rounds were fired, sources told The Times. The deputy was airlifted to Loma Linda University Medical Center, where he died of his wounds.

The afternoon gun battle was part of a quickly changing situation that began after Dorner allegedly broke into a home, tied up a couple and held them hostage before fleeing with their white pickup truck, authorities said.

Then Dorner was allegedly spotted by a state Fish and Wildlife officer in the pickup truck, sources said. A vehicle-to-vehicle shootout ensued. The officer's vehicle was peppered with multiple rounds, according to authorities.

Dorner crashed his vehicle and took refuge in a nearby cabin, sources said. One deputy was hit as Dorner fired out of the cabin and a second deputy was injured when Dorner exited the back of the cabin, deployed a smoke bomb and opened fire again in an apparent attempt to flee. Dorner was driven back inside the cabin, the source said.

During the unprecedented manhunt, officers had crisscrossed California for days pursuing the more than 1,000 tips that poured in about Dorner's possible whereabouts -- including efforts in Tijuana, San Diego County and Big Bear -- and serving warrants at homes in Las Vegas and the Point Loma area of San Diego.

Statewide alerts were issued in California and Nevada, and border authorities were alerted. The Transportation Security Administration also had issued an alert urging pilots and other aircraft operators to keep an eye out for Dorner.

The search turned to Big Bear last week after Dorner's burning truck was found on a local forest road.

At the search's height, more than 200 officers scoured the mountain, conducting cabin-by-cabin checks. It was scaled back Sunday -- about 30 officers were out in the field Tuesday, the San Bernardino County Sheriff's Department said.

Dorner allegedly threatened "unconventional and asymmetrical warfare" against police in a lengthy manifesto that authorities say he posted on Facebook. The posting named dozens of potential targets, including police officers, whom Dorner allegedly threatened to attack, according to authorities.

Records state that the manifesto was discovered by authorities Wednesday, three days after the slaying of an Irvine couple: Monica Quan, a Cal State Fullerton assistant basketball coach, and her fiance, Keith Lawrence, a USC public safety officer.

Quan was the daughter of a retired LAPD captain whom Dorner allegedly blamed in part for his firing from the force in 2009.
