Bomb Strikes Disputed Iraqi City of Kirkuk

BAGHDAD (AP) — A powerful suicide car bomb struck the local headquarters for the party of a key Kurdish leader early Wednesday in the disputed Iraqi city of Kirkuk, killing at least four and wounding dozens, according to officials.

The blast outside the offices of the Kurdistan Democratic Party caused widespread damage, mangling cars and tearing apart storefronts. The KDP is led by Massoud Barzani, the president of Iraq's largely autonomous Kurdish region, who has frequently sparred with Iraq's central governor in Baghdad.

Kirkuk provincial council chairman Hassan Torhan said 90 people have been wounded, suggesting the death toll could rise.

The blast comes amid rising tensions along Iraq's ethnic and sectarian divide.

Kirkuk, 290 kilometers (180 miles) north of Baghdad, is home to a mix of Arabs, Kurds and Turkomen, who all have competing claims to the oil-rich area. The Kurds want to incorporate it into their self-ruled region in Iraq's north, but Arabs and Turkomen are opposed.

The city is at the heart of a snaking swath of territory disputed between the Kurds, who have their own armed fighting force, and Iraq's central government. A shootout in another area along the contested area prompted both sides to rush troops and heavy weapons to the area in November.

Violence has fallen since the peak of insurgency several years ago, but lethal attacks still occur frequently.

There was no immediate claim of responsibility for Tuesday's attacks, but car bombs are the hallmark of Sunni insurgents such as al-Qaida in Iraq.

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.

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.

California to Give Web Courses a Big Trial

A plan to offer an array of online college classes at a California state university could, if the students are successful, open the door to teaching hundreds of thousands of California students at a lower cost via the Internet.

Udacity, a Silicon Valley start-up that creates online college classes, will announce a deal on Tuesday with San Jose State University for a series of remedial and introductory courses.

Because the courses are intended to involve the classroom instructor, it could also help to blunt professors’ unease with the online classes. 

The state university’s deal with Udacity is also the first time that professors at a university have collaborated with a provider of a MOOC — massive open online course — to create for-credit courses with students watching videos and taking interactive quizzes, and receiving support from online mentors.

Eventually, such courses could be offered to hundreds of thousands of students in the state.

California Gov. Jerry Brown, who has been pushing state universities to move more aggressively into online education, approached the company to come up with a technological solution for what has become a vexing challenge for the state.

Ellen N. Junn, provost and vice president for academic affairs at the university in San Jose, said the California State University System faces a crisis because more than 50 percent of entering students cannot meet basic requirements.

“They graduate from high school, but they cannot pass our elementary math and English placement tests,” she said.

The Udacity pilot program will include a remedial algebra course, a college-level algebra course and introductory statistics.

For the pilot project starting this month, however, the courses will be limited to 300 students — half from San Jose State University, and half from local community colleges and high schools — who will pay lower than usual tuition. The cost of each three-unit course will be $150, significantly less than regular San Jose State tuition. Sebastian Thrun, one of the founders of Udacity, would not disclose how much the company would be paid for its participation.

San Jose State will receive funds from the National Science Foundation to study the effectiveness of the new online classroom design.

Open online courses exploded in American higher education in 2011 after Mr. Thrun, a nationally known artificial-intelligence researcher at Stanford, and Peter Norvig, Google’s director of research, offered to teach an introductory artificial-intelligence course online. More than 160,000 students initially registered for the class.

After two other Stanford courses each attracted more than 100,000 students, Dr. Thrun started his venture. Two other Stanford computer scientists, Andrew Ng and Daphne Koller, also established a competing private company, Coursera, to develop technologies necessary to change the reach and effectiveness of online education.

The courses have rapidly moved from the periphery to the center of higher education policy as a growing number of schools have begun experimenting with ways to offer the courses for credit toward a degree.

EdX, a university collaboration initiated by the Massachusetts Institute of Technology and Harvard last year, this month will begin offering some of its courses at two Massachusetts community colleges, in a blended format.

Recently edX completed a pilot offering of its difficult circuits and electronics course at San Jose State to stunning results: while 40 percent of the students in the traditional version of the class got a grade of C or lower, only 9 percent in the blended edX class got such a low grade.

Last fall, for the first time, Udacity’s courses were tried on a small group of struggling high school students, at the Winfree Academy Charter School system, a cluster of schools near Dallas-Fort Worth created to help struggling students and reclaim dropouts.

“I was a little scared to put our kids, who are struggling and at risk of dropping out, into a class written by a Stanford professor,” said Melody Chalkley, Winfree’s founder. “But of the 23 students who used Udacity, one withdrew from the school, and the other 22 all finished successfully. And two young women got through the whole physics course in just two weeks.”

Well: Turning to the Web for a Medical Diagnosis

Thirty-five percent of American adults said they have used the Internet to diagnose a medical condition for themselves or someone else, according to a new Pew Research Center study. Women are more likely than men to turn to the Internet for diagnoses. Other groups more likely to do so are younger people, white adults, people with college degrees and those who live in households with income above $75,000.

The study, released by Pew’s Internet and American Life Project on Tuesday, points out that Americans have always tried to answer their health questions at home, but that the Internet has expanded the options for research. Previous surveys have asked questions about online diagnoses, but the Pew study was the first to focus on the topic with a nationally representative sample, said Susannah Fox, an associate director at Pew Internet. Surveyors interviewed 3,014 American adults by telephone, from August to September 2012.

Of the one in three Americans who used the Internet for a diagnosis, about a third said they did not go to a doctor to get a professional medical opinion, while 41 percent said a doctor confirmed their diagnosis. Eighteen percent said a doctor did not agree with their diagnosis. As far as where people start when researching health conditions online, 77 percent said they started at a search engine like Google, Bing or Yahoo, while 13 percent said they began at a site that specializes in health information.
