Robert L. Citron dies at 87; central figure in O.C. bankruptcy

Robert L. Citron, the Orange County treasurer whose bad bets on exotic Wall Street investments resulted in what at the time was the largest municipal bankruptcy in U.S. history, died Wednesday. He was 87.

Citron died at St. Joseph Hospital in Orange of complications from a heart attack, said his wife, Terry Citron.

Until the 1994 financial collapse, Citron was a low-key bureaucrat who won praise from Orange County supervisors for earning much higher yields from the county's complex array of investments than many other government agencies. His investment pools attracted funds from governments around the country as well as from schools, cities and public agencies.

The county declared bankruptcy Dec. 6, 1994, buffeted by losses that, when the final count was tallied, amounted to $1.64 billion. The county was forced to postpone repayments on bonds it had sold, ruining its credit rating, but eventually repaid its creditors in full. The bankruptcy sent shock waves through Wall Street and the municipal bond markets. It also made national headlines, with some asking how such a prosperous county could become insolvent.

A grand jury investigation would later find that the treasurer who over the years won so much praise for his investment skills relied upon a mail order astrologer and a psychic for interest rate predictions as the county's treasury began to falter.

Citron pleaded guilty to six felony counts, including filing false statements to participants in the Orange County Treasury Investment Pool. His lawyer, David Wiechert, submitted medical testimony indicating that Citron was in the early stages of dementia.

Citron was sentenced to work in the county jail, sorting inmates' requests for personal items by day before returning to his home in Santa Ana. He never spent a night behind bars but worked for months in the jail's commissary. He remained on probation until 2002.

In a 1997 interview with The Times, Citron insisted that he was duped into making rashly imprudent investments by Merrill Lynch. He became a key witness in Orange County's $2-billion lawsuit against the investment giant. The suit said that Citron was a "pigeon" for greedy brokers at the investment house.

Merrill Lynch maintained that the bankruptcy was Citron's fault. It later settled the case with the county, paying $400 million.

A third-generation Californian, Citron was born in Los Angeles on April 14, 1925, according to public records, and grew up in Burbank. Because he had asthma as a child, his family moved out to the town of Hemet in the foothills of the San Jacinto Mountains. His father, Jesse, was a doctor who earned a measure of fame for being liquor-loving W.C. Fields' doctor and weaning him off Scotch.

Citron rose through the ranks of the county's treasury department to become county treasurer-tax collector, a post he held for 24 years. He was one of the few Democrats to hold countywide elected office in a region dominated by Republicans. He lived in Santa Ana, just a few miles from work, and was famous for his long hours. In a 1994 interview, his wife told The Times that the weekends were hardest for her husband because he could not go to work.

"He can barely stand the weekend at home," she said. "He can't wait to get back. I think he'd go crazy without that job."

The bankruptcy tarnished Citron's name as well as the county's. County government slashed hundreds of jobs and cut budgets. Orange County's repayment plan siphoned money from four county departments every year, affecting projects big and small.

Citron's assistant, Matthew Raabe, was convicted of fraud and misappropriation and served 41 days in jail before the verdict was overturned. Taxpayers spent $1 million on his defense. The county's financial director, Ronald S. Rubino, was tried on fraud and misappropriation charges, but a jury deadlocked in favor of acquittal. He pleaded no contest to one record-keeping violation under a deal that allowed his record to be erased after a year. County Supervisors Roger R. Stanton and William G. Steiner were indicted by a grand jury on grounds of failing to safeguard public funds. The indictment was later dismissed by an appeals court ruling that said failing to do their jobs wasn't a crime.

Citron is survived by his wife of 57 years.

Jersey Shore town OKs deal to rebuild boardwalk

SEASIDE HEIGHTS, N.J. (AP) — The boardwalk where generations of families and teens got their first taste of the Jersey Shore and where the MTV reality show of the same name was filmed is about to be rebuilt following its destruction in Superstorm Sandy.

Seaside Heights on Wednesday night was awarded a $ 3.6 million contract to have the boardwalk rebuilt in time for Memorial Day weekend.

The walkway, one of the most popular and heavily used at the Jersey Shore, was destroyed in the late October storm, the state’s worst natural disaster. Officials say it is the centerpiece of the borough’s tourism industry, which funds 75 percent of its budget.

“A lot of people love Seaside and want to see what’s happening this year,” Mayor William Akers said. “If they don’t come back, we don’t eat.”

Florence Birban, a 47-year resident, said the boardwalk means a lot to homeowners.

“We need a boardwalk here to bring in the revenue and keep our taxes from going up, hopefully,” she said. “It just looks wrong without a boardwalk. I look up the street, and I don’t see one, and it’s not right.”

The work should be done by May 10.

Seaside Heights was famous for generations as a summer destination for families, teens and young adults. It took on a new level of fame in recent years when MTV set its “Jersey Shore” reality show on the boardwalk, where a tipsy Nicole “Snooki” Polizzi tottered unsteadily and Mike “The Situation” Sorrentino flexed his abs as cameras whirred.

The contract approved Wednesday just covers replacement of the boards and the substructure beneath it. Akers said a future contract will include ramps, railings and a protective sea wall.

Borough Administrator John Camera said the entire length of the mile-long boardwalk will be rebuilt.

That was good news for Sue Poane, another longtime resident concerned about the town’s financial future and its quality of life.

“We need the people to spend their money here; we need the boardwalk back for the businesses,” she said. “My husband and I walk the boardwalk every Sunday afternoon. We have our supper at our special place — they have the best seafood in the world! — and then we sit and people-watch.”

Seaside Heights is the second major boardwalk to see rebuilding begin; Belmar started work on its walkway last week. Spring Lake also has started fixing its boardwalk, as has Point Pleasant Beach.

On Thursday in Seaside Heights, the private owners of the Jet Star roller coaster plan to solicit bids from companies interested in removing the remains from the Atlantic Ocean, Akers said. They have been there since the roller coaster plunged off a collapsing pier during the storm.

Town officials are anxious to have it removed. Last week, a man sailed a small boat to the coaster, climbed to the top of it and affixed a flag to it before being talked down and arrested by police. Officials and some residents are worried about liability for the coaster if someone is injured on or near it. The beachfront remains off-limits and is guarded by police and state troopers.

Some With Autism Diagnosis Can Recover, Study Finds

Doctors have long believed that disabling autistic disorders last a lifetime, but a new study has found that some children who exhibit signature symptoms of the disorder recover completely.

The study, posted online on Wednesday by the Journal of Child Psychology and Psychiatry, is the largest to date of such extraordinary cases and is likely to alter the way that scientists and parents think and talk about autism, experts said.

Researchers on Wednesday cautioned against false hope. The findings suggest that the so-called autism spectrum contains a small but significant group who make big improvements in behavioral therapy for unknown, perhaps biological reasons, but that most children show much smaller gains. Doctors have no way to predict which children will do well.

Researchers have long known that between 1 and 20 percent of children given an autism diagnosis no longer qualify for one a few years or more later. They have suspected that in most cases the diagnosis was mistaken; the rate of autism diagnosis has ballooned over the past two decades, and some research suggests that it has been loosely applied.

The new study should put some of that skepticism to rest.

“This is the first solid science to address this question of possible recovery, and I think it has big implications,” said Sally Ozonoff of the MIND Institute at the University of California, Davis, who was not involved in the research. “I know many of us as would rather have had our tooth pulled than use the word ‘recover,’ it was so unscientific. Now we can use it, though I think we need to stress that it’s rare.”

She and other experts said the findings strongly supported the value of early diagnosis and treatment.

In the study, a team led by Deborah Fein of the University of Connecticut at Storrs recruited 34 people who had been diagnosed before the age of 5 and no longer had any symptoms. They ranged in age from 8 to 21 years old and early in their development were in the higher-than-average range of the autism spectrum. The team conducted extensive testing of its own, including interviews with parents in some cases, to gauge current social and communication skills.

The debate over whether recovery is possible has simmered for decades and peaked in 1987, when the pioneering autism researcher O. Ivar Lovaas reported that 47 percent of children with the diagnosis showed full recovery after undergoing a therapy he had devised. This therapy, a behavioral approach in which increments of learned skills garner small rewards, is the basis for the most effective approach used today; still, many were skeptical and questioned his definition of recovery.

Dr. Fein and her team used standardized, widely used measures and found no differences between the group of 34 formerly diagnosed people and a group of 34 matched control subjects who had never had a diagnosis.

“They no longer qualified for the diagnosis,” said Dr. Fein, whose co-authors include researchers from Queens University in Kingston, Ontario; Children’s Hospital of Philadelphia; the Institute of Living in Hartford; and the Child Mind Institute in New York. “I want to stress to parents that it’s a minority of kids who are able to do this, and no one should think they somehow missed the boat if they don’t get this outcome.”

On measures of social and communication skills, the recovered group scored significantly better than 44 peers who had a diagnosis of high-functioning autism or Asperger’s syndrome.

Dr. Fein emphasized the importance of behavioral therapy. “These people did not just grow out of their autism,” she said. “I have been treating children for 40 years and never seen improvements like this unless therapists and parents put in years of work.”

The team plans further research to learn more about those who are able to recover. No one knows which ingredients or therapies are most effective, if any, or if there are patterns of behavior or biological markers that predict such success.

“Some children who do well become quite independent as adults but have significant anxiety and depression and are sometimes suicidal,” said Dr. Fred Volkmar, the director of the Child Study Center at the Yale University School of Medicine. There are no studies of this group, he said.

That, because of the new study, is about to change.

State of the Art: Imagining Ho-Hum C.E.S. as an Action Movie - State of the Art

Hi boss! I’m back from the Consumer Electronics Show in Las Vegas. You assigned me to report on what’s new and exciting, but I have some bad news. The answer is: almost nothing.

I mean, think about it: Apple, Google, Microsoft and Facebook don’t even attend C.E.S.; they’d rather make their product announcements on their own schedules without being locked into this every-January thing. It’s still a big show, bigger than ever this year, with 3,200 exhibits and 150,000 attendees, but I wonder why people bother. Whose product announcement will get any press at all when it’s buried by 3,199 others?

C.E.S.’s organizers publish a daily magazine during the show that profiles new products announced there. Here are some actual examples: “Braven Expands Bluetooth Speaker Line.” “Armpocket Unveils Smartphone Cases.” “Bits Ltd. Expands Line of Surge Protectors.”

So if you want an exciting column from me, the thrills won’t come from the news of new products at C.E.S. I’ll have to spice things up another way. See what you think of this.

As he plummets toward the Nevada desert, two deafening sounds assail Daxton Blackthorne’s eardrums — the wind rushing past his ears at terminal velocity, and a deafening explosion over his head. Fumbling for his parachute cord, he’s blasted by the searing heat from the fireball that, until seconds ago, was his Cessna Citation.

For now, though, his concern isn’t the air-to-air missile that has just dispatched his jet, courtesy of the Bora Boran Mafia on his tail. It isn’t even the fact that Daxton Blackthorne is all that stands between them and the collapse of American democracy.

It’s finding a good place to land.

There! Squinting in the blinding sun, he spots an enormous chain of low-slung buildings, stretching through the bustling downtown like a sleeping cobra: the Las Vegas Convention Center.

He hits the roof of the South Hall hard — too hard. Keeping low, he scuttles across the gravel to a ventilation shaft and emerges, moments later, in a blasting cacophony of color, sound and electronics.

He hears the crash of boots behind him as his pursuers explode from the same shaft. Got to move, Daxton thinks. Detaching his ’chute, he darts among the booths, dodging clumps of buyers, reporters and electronics executives.

He weaves among the exhibits, barely noting their wares. External battery packs for phones. Car chargers for phones. Screen protectors for phones. Cases for phones.

What is this place? he thinks, pulse pounding.

Booth after booth. GPS units. Tablets. Earbuds. Bluetooth speakers. Phone cases. Row after row of Chinese manufacturers he’s never heard of. Like this one, Huwei, selling the world’s largest Android phone — the thin, shiny Ascend Mate, with a 6.1-inch screen. That’d be like talking into a cutting board, he thinks.

He bursts into the Central Hall, and the sensory overload is immediate; he pauses, gasping, to take it in. TV screens. Thousands. Screens bigger than a man. Screens stacked up to the distant ceiling. Screens brighter and louder than explosives in the morning. Sharp, Sony, Samsung, LG, Toshiba, Panasonic. The bombardment is almost as lethal as the one that took down his Cessna.

Here are OLED screens, with incredibly black blacks, vivid colors and razor-thin bodies; this LG model is only 0.16 inches thick. Panasonic and Sony each claim “the world’s largest OLED screen” — 56-inch prototypes.

Footsteps pound behind him. Too late to run. He’ll blend in. He merges into a throng of eager showgoers.

“Three-D may have been a flop,” a rep is saying. “But this year, the industry is back with an irresistible offering: 4K television. Ultra HD, we call it. You thought HDTV was sharp? Now imagine: four times as many pixels. Stunning picture quality, in stunning screen sizes.”

Daxton figures you’d have to sit pretty darned close to see any difference between HDTV and 4KTV. But never mind that — out of the corner of his eye, Daxton spots the black uniforms of his pursuers, fanning through the crowd. Play along, he thinks. “Excuse me,” he shouts in a faux French accent. “What is there to watch in 4K?”

“Unfortunately, 4K video requires too much data for today’s cable, satellite, broadcast, Blu-ray, or Internet streaming,” is the reply. “But at Sony, we’re leading the way! If you buy our 84-inch 4K television for $25,000, we’ll lend you a hard drive with 10 Sony movies on it — in gorgeous 4K.”

Daxton can think of better uses for $25,000; a jetpack would come in handy right about now. He dives into the crowd. Must. Find. Disguise.

A crowd wearing headsets is gathered before a Samsung TV. That’ll do. He grabs one; it covers both his eyes and his ears.

“You’re seeing a prototype of Samsung’s OLED dual-view technology,” the spokesman says. “This TV can display two 3-D video sources simultaneously, or four regular ones. Imagine: Your children can be playing Xbox while you watch the Super Bowl!” Daxton moves the switch on the earpiece; sure enough, the TV’s image changes accordingly, along with the audio from the tiny earpiece speakers.

But angry shouts in Tahitian are closing in. He bolts through an archipelago of audio booths, hawking celebrity headphones bearing the names of the rapper 50 Cent, the heavy-metal band Motorhead, the runner Usain Bolt, the N.F.L. quarterback Tim Tebow and the TV reality star Snooki. When did Snooki become an audiophile? he wonders.

By the time he storms into the North Hall, his lungs are screaming. He stands, panting, in a broader area populated by gleaming, polished automobiles. Here are Ford and General Motors, announcing new developer programs, open platforms for new apps that will run on their cars’ computer screens. Ford’s Sync AppLink bans games and video apps, for safety reasons. Good thinking, Daxton thinks. Wouldn’t want distracted driving.

Here are Audi and Lexus, announcing self-driving cars. Glancing at the video loop, he notes that the Audi prototype can, at this point, drive itself only through specially equipped parking garages, like the one set up at the Mandarin Oriental for a demonstration.

But on the Lexus stage, he spots something much more enticing: a car, festooned with sensors, that can actually drive itself on regular roads, much like Google’s fleet of 12 autonomous cars.

“California and Nevada have both made self-driving cars legal, with certain restrictions,” the executive on stage says. “And this Lexus LS safety-research vehicle is a pioneer. The 360-degree laser on the roof detects objects up to 230 feet away; the front camera knows if the traffic light is red or green. Side cameras, GPS and radar enhance what could someday be a safe, efficient, road-aware vehicle.”

There’s a burst of commotion from Daxton’s near right. It’s them. He vaults onto the stage. “Love the idea of self-driving cars,” Daxton tells the presenter. “But right now, I need a car I can drive myself.”

A saber blade shatters the air next to his ear. With a burst of adrenaline, he dives through the open window of the Lexus. His assailants push through the crowd and clamber after him, but he’s already powered on the car. Huddling low, he guns the engine and shifts into gear.

As a hail of bullets shatters the rear window, the Lexus arcs off the stage, plows through seven rotating shelves of phone cases, and, in a cloud of plaster and twisted beams, erupts through the wall of the convention center.

With a wry smile, Daxton adjusts his rear-view mirror just in time to see the knot of black-suited Bora Borans shaking their fists in the distance.

He brushes some safety glass off his shoulder, slips on sunglasses, and leans back into the leather seat.

“Now that’s what I call an exciting show,” he says, grinning, and he swings onto the open road for home.

This article has been revised to reflect the following correction:

Correction: January 17, 2013

An earlier version of this article misspelled the name of a Chinese technology company. It is Huawei, not Huwei.

All Boeing 787 Dreamliner jets in Japan grounded

All 24 of Japan's Boeing 787 Dreamliner passenger jets were grounded for safety checks after one of the planes operated by All Nippon Airways made an emergency landing in western Japan.

Details of the problem were still being checked, ANA spokesman Takuya Taniguchi said Wednesday after the flight to Tokyo from Ube landed at the Takamatsu airport, where NTV television reported passengers had used emergency slides to exit the jet. The airport was temporarily closed.

The plane landed after a cockpit message showed battery problems. It was the latest of a series of problems including a battery fire and a fuel leak on ANA Dreamliners parked at Logan International Airport in Boston last week. No one has been seriously injured in any of the incidents.

Japan's Transport Ministry said the airlines that operate Dreamliners had grounded the planes voluntarily. ANA operates 17 of the jets and Japan Airlines has seven. The Japanese planes represent almost half of the 50 Dreamliners being flown commercially worldwide.

After the Boston incidents, the Federal Aviation Administration launched an unusual "comprehensive safety review of Boeing 787 critical systems," including a sweeping evaluation of the way that Boeing designs, manufactures and assembles the aircraft.

Boeing said it would participate in the review with the FAA and believed the process would bolster the public's confidence in the reliability of the aircraft.

The move came despite an "unprecedented" certification process for the 787 in which FAA technical experts logged 200,000 hours of work over nearly two years and flew on numerous test flights, FAA Administrator Michael Huerta said. There were more than a dozen new special conditions developed during the certification because of the Dreamliner's innovative design.

Certification of the Dreamliner was completed Aug. 25, 2011, and the first plane was delivered to All Nippon Airways a month later. It was more than three years late because of design problems and supplier issues.

The Dreamliner, a twin-aisle aircraft that can seat 210 to 290 passengers, is the first large commercial jet with more than half its structure made of composite materials (carbon fibers meshed together with epoxy) rather than aluminum sheets. Another innovative application is the change from hydraulically actuated systems typically found on passenger jets to electrically powered systems involving lithium ion batteries.

Times staff writers W.J. Hennigan in Los Angeles and David Pierson in Shanghai contributed to this report.

Japanese filmmaker Nagisa Oshima dies aged 80

(Reuters) – Japanese film director Nagisa Oshima, best known for the sexually explicit film “In the Realm of the Senses” and “Merry Christmas, Mr. Lawrence“, has died from pneumonia, aged 80.

The Hollywood Reporter said Oshima died on Tuesday in Fujisawa, south of Tokyo, where he had been living since retiring from making movies.

The British Film Institute described Oshima as one of the major directors of the new wave of Japanese cinema in the 1960s whose politically charged films contrasted starkly with the stylistic conservatism of classical Japanese filmmaking.

A law graduate, he began his filmmaking career at the age of 26 with the 1959 movie “A Town of Love and Hope”.

But his international notoriety was ensured in 1976 with “In the Realm of the Senses,” a graphic portrayal of insatiable sexual desire between a hotel owner and one of his maids in 1930s Japan.

The film contained scenes of unsimulated sexual activity and had to be registered as a French production to bypass Japanese censorship laws. Its uncensored version remains unavailable in Japan.

Oshima won the best director award at the Cannes Film Festival in 1978 for his film “Empire of Passion,” another erotic tale.

He teamed up with British actor/singer David Bowie on the 1983 film “Merry Christmas, Mr. Lawrence,” based on author Laurens van der Post’s experiences as a prisoner of war in Japan during World War Two.

Oshima suffered a stroke in 1996 but recovered enough to return briefly to filmmaking, making his final film “Taboo” in 1999, a movie about gay samurai.

Well: Boosting Your Flu Shot Response

Phys Ed

Gretchen Reynolds on the science of fitness.

As this year’s influenza season continues to take its toll, those procrastinators now hurrying to get a flu shot might wish to know that exercise may amplify the flu vaccine’s effect. And for maximal potency, the exercise should be undertaken at the right time and involve the right dosage of sweat, according to several recent reports.

Flu shots are one of the best ways to lessen the risk of catching the disease. But they are not foolproof. By most estimates, the yearly flu vaccine blocks infection 50 to 70 percent of the time, meaning that some of those being inoculated gain little protection. The more antibodies someone develops, the better their protection against the flu, generally speaking. But for some reason, some people’s immune systems produce fewer antibodies to the influenza virus than others’ do.

Being physically fit has been found in many studies to improve immunity in general and vaccine response in particular. In one notable 2009 experiment, sedentary, elderly adults, a group whose immune systems typically respond weakly to the flu vaccine, began programs of either brisk walking or a balance and stretching routine. After 10 months, the walkers had significantly improved their aerobic fitness and, after receiving flu shots, displayed higher average influenza antibody counts 20 weeks after a flu vaccine than the group who had stretched.

But that experiment involved almost a year of dedicated exercise training, a prospect that is daunting to some people and, in practical terms, not helpful for those who have entered this flu season unfit.

So scientists have begun to wonder whether a single, well-calibrated bout of exercise might similarly strengthen the vaccine’s potency.

To find out, researchers at Iowa State University in Ames recently had young, healthy volunteers, most of them college students, head out for a moderately paced 90-minute jog or bike ride 15 minutes after receiving their flu shot. Other volunteers sat quietly for 90 minutes after their shot. Then the researchers checked for blood levels of influenza antibodies a month later.

Those volunteers who had exercised after being inoculated, it turned out, exhibited “nearly double the antibody response” of the sedentary group, said Marian Kohut, a professor of kinesiology at Iowa State who oversaw the study, which is being prepared for publication. They also had higher blood levels of certain immune system cells that help the body fight off infection.

To test how much exercise really is required, Dr. Kohut and Justus Hallam, a graduate student in her lab, subsequently repeated the study with lab mice. Some of the mice exercised for 90 minutes on a running wheel, while others ran for either half as much time (45 minutes) or twice as much (3 hours) after receiving a flu shot.

Four weeks later, those animals that, like the students, had exercised moderately for 90 minutes displayed the most robust antibody response. The animals that had run for three hours had fewer antibodies; presumably, exercising for too long can dampen the immune response. Interestingly, those that had run for 45 minutes also had a less robust response. “The 90-minute time point appears to be optimal,” Dr. Kohut says.

Unless, that is, you work out before you are inoculated, another set of studies intimates, and use a dumbbell. In those studies, undertaken at the University of Birmingham in England, healthy, adult volunteers lifted weights for 20 minutes several hours before they were scheduled to receive a flu shot, focusing on the arm that would be injected. Specifically, they completed multiple sets of biceps curls and side arm raises, employing a weight that was 85 percent of the maximum they could lift once. Another group did not exercise before their shot.

After four weeks, the researchers checked for influenza antibodies. They found that those who had exercised before the shot generally displayed higher antibody levels, although the effect was muted among the men, who, as a group, had responded to that year’s flu vaccine more robustly than the women had.

Over all, “we think that exercise can help vaccine response by activating parts of the immune system,” said Kate Edwards, now a lecturer at the University of Sydney, and co-author of the weight-training study.

With the biceps curls, she continued, the exercises probably induced inflammation in the arm muscles, which may have primed the immune response there.

As for 90 minutes of jogging or cycling after the shot, it probably sped blood circulation and pumped the vaccine away from the injection site and to other parts of the body, Dr. Kohut said. The exercise probably also goosed the body’s overall immune system, she said, which, in turn, helped exaggerate the vaccine’s effect.

But, she cautions, data about exercise and flu vaccines is incomplete. It is not clear, for instance, whether there is any advantage to exercising before the shot instead of afterward, or vice versa; or whether doing both might provoke the greatest response – or, alternatively, be too much and weaken response.

So for now, she says, the best course of action is to get a flu shot, since any degree of protection is better than none, and, if you can, also schedule a visit to the gym that same day. If nothing else, spending 90 minutes on a stationary bike will make any small twinges in your arm from the shot itself seem pretty insignificant.

Rights Group Reports on Abuses of Surveillance and Censorship Technology

A Canadian human rights monitoring group has documented the use of American-made Internet surveillance and censorship technology by more than a dozen governments, some with harsh human rights policies like Syria, China and Saudi Arabia.

Jakub Dalek of the Munk School of Global Affairs.

Thor Swift for The New York Times

Morgan Marquis-Boire led the research with Mr. Dalek.

The Citizen Lab Internet research group, based at the Munk School of Global Affairs at the University of Toronto, used computer servers to scan for the distinctive signature of gear made by Blue Coat Systems of Sunnyvale, Calif.

It determined that Egypt, Kuwait, Qatar, Saudi Arabia and the United Arab Republic employed a Blue Coat system that could be used for digital censorship. The group also determined that Bahrain, China, India, Indonesia, Iraq, Kenya, Kuwait, Lebanon, Malaysia, Nigeria, Qatar, Russia, Saudi Arabia, South Korea, Singapore, Thailand, Turkey and Venezuela used equipment that could be used for surveillance and tracking.

The authors said they wanted to alert the public that there was a growing amount of surveillance and content-filtering technology distributed throughout the Internet. The technology is not restricted from export by the State Department, except to countries that are on embargo lists, like Syria, Iran and North Korea.

“Our findings support the need for national and international scrutiny of the country Blue Coat implementations we have identified, and a closer look at the global proliferation of dual-use information and communications technology,” the group noted. “We hope Blue Coat will take this as an opportunity to explain their due diligence process to ensure that their devices are not used in ways that violate human rights.”

A spokesman for Blue Coat Systems said the firm had not seen the final report and was not prepared to comment.

In 2011, several groups, including Telecomix and Citizen Labs, raised concerns that Blue Coat products were being used to find and track opponents of the Syrian government. The company initially denied that its equipment had been sold to Syria, which is subject to United States trade sanctions.

Shortly afterward, Blue Coat reversed itself and acknowledged that the systems were indeed in Syria, but it said that the devices had been shipped to a distributor in Dubai, and said that it thought that they had been destined for the Iraqi Ministry of Communications.

The Citizen Lab research project was led by Morgan Marquis-Boire and Jakub Dalek. Mr. Marquis-Boire, a Google software engineer, has during the last year been involved in a variety of research projects aimed at exposing surveillance tools used by authoritarian regimes. He said that he carefully segregated his work at Google from his human rights research.

Last year, Mr. Marquis-Boire used computer servers to identify the use of an intelligence-oriented surveillance software program, called FinSpy, which was being used by Bahrain to track opposition activists.

On a hunch last month, the researchers used the Shodan search engine, a specialized Internet tool intended to help identify computers and software services that were connected to the Internet. They were able to identify a number of the Blue Coat systems that are used for content filtering and for “deep packet inspection,” a widely used technology for detecting and controlling digital content as it travels through the Internet.

The researchers stressed that they were aware that there were both benign and harmful uses for the Blue Coat products identified as ProxySG, which functions as a Web filter, and a second system, PacketShaper, which can detect about 600 Web applications and can be used to control undesirable Web traffic.

“I’m not trying to completely demonize this technology,” Mr. Marquis-Boire said.

The researchers also noted that the equipment does not directly fall under the dual-use distinction employed by the United States government to control the sale of equipment that has both military and civilian applications, but it can be used for both political and intelligence applications by authoritarian governments.

“Syria is subject to U.S. export sanctions,” said Sarah McKune, a senior researcher at the Citizen Lab. “When it comes to other countries that aren’t subject to U.S. sanctions it’s a more difficult situation. There could still be significant human rights impact.”

The researchers also noted that a large number of American and foreign companies supplied similar gear in what Gartner, the market research firm, described as a $1.02 billion market in a report issued in May 2012.

The researchers said that some American security technology companies, like Websense, had taken strong human rights stands, but had declined to grapple with the issue of the possible misuse of the technology.
