How to Win Facebook Friends and Influence People

Instead of picketing outside company headquarters, an advocacy group is using Facebook ads to try to influence people whose profiles identify them as employees of Freddie Mac or JPMorgan Chase.

The anti-foreclosure ad campaign, which launches today, asks Freddie and Chase employees to talk to their CEOs about a veteran -- a former Marine -- who's facing eviction in California.

"This is not any sort of attack on the employees there," said Jim Pugh of Rebuild the Dream, which is running the ad campaign. "We're trying to let them know what's happening."

The ad that targets Freddie Mac employees features a small picture of CEO Charles Haldeman's face, and the message, "Freddie Mac did what???? Freddie Mac is evicting a former Marine who's been trying to pay his mortgage. Tell CEO Haldeman to work out a fair deal with him!" according to a copy of the ad provided by Pugh.

The JPMorgan Chase ad is similar, but with a Chase logo instead of an executive's face.  

We've contacted Freddie Mac and JP Morgan Chase spokespeople for comment, and also reached out to Freddie Mac and JPMorgan Chase employees on Facebook. If you've seen one of these ads, please let us know.

 Targeted online advertising is nothing new. (As anyone who has changed their Facebook status to "engaged" can tell you, a simple update can bring a deluge of new ads.) But political campaigns and advocacy groups are increasingly adopting the same microtargeting tactics that companies use.  

Rick Perry's campaign, for instance, targeted faith-focused ads to people in Iowa who listed themselves as Christians on Facebook, and ads featuring his wife to the state's female conservatives, Politico reported.  

According to FEC data, Endorse Liberty, a super PAC that supports Ron Paul, has led the way on Facebook expenditures, spending a total of $241,508 through January 2012.

And it's not just Facebook and Google where campaigns and activists are doing microtargeting. The music site Pandora announced last year that it would be selling political ad space targeted to the zip codes of particular listeners, the Wall Street Journal reported.

There's nothing inherently problematic about targeted ads. Campaigns have been using direct mail to target particular voters for decades. Digital targeting can be a cost-effective way of spending advertising dollars, especially for smaller groups, like Rebuild the Dream, which sees the ads as a great way to get more bang for their buck in terms of reaching their intended audience. (The group also launched a special donation drive specifically for the Facebook ad buy.) ProPublica even used Facebook ads to try to find sources for our 2009 series, When Caregivers Harm.

But as the ability to use data to reach particular people grows more sophisticated, targeting risks crossing privacy lines, as demonstrated by a recent New York Times article on how Target knew a teenage customer was pregnant before her father did.

What's clear is that if all this microtargeting translates into electoral gains, the scale and sophistication of these efforts will continue to grow, and the data science that gained traction in 2008 will become a regular part of campaigning. In the meantime, the Obama campaign's already substantial data team continues to hire statistical modeling analysts and analytics engineers.

The increasing ease and flexibility of online targeting also raises new questions about how politicians are presenting themselves to different audiences, how much campaigns need to tell their supporters about the personal information they collect -- and what will happen to the massive databases of voter information collected during the 2012 presidential campaign. Will they be sold? Passed on to other politicians?

Rebuild the Dream, which focuses on economic issues, was launched by MoveOn.org in 2011, but has been independent since January, Pugh said. The group's president is former Obama green jobs adviser Van Jones.

Pugh worked on the Obama campaign's digital analytics team in 2008 while also trying to finish a Ph.D. dissertation in robotics, and later did similar work for the Democratic National Committee. He said he was not sure what kind of reaction the ads would receive.

"I would imagine that people are fairly used to targeted ads at this point," he said. But while people who work in politics and advocacy may be used to receiving Facebook ads targeting specific causes, "It's hard to know in advance how unusual it will seem to the employees of Freddie Mac and JP Morgan Chase."

Six Ways Fukushima is Not Chernobyl by Lois Beckett, Special to ProPublica



Six Ways Fukushima is Not Chernobyl

by Lois Beckett, Special to ProPublica March 18, 2011, 1:22 p.m.

The crisis at Japan's Fukushima Daiichi has already been dubbed the worst nuclear accident since Chernobyl, and the situation there continues to worsen.

But along with references to the "ch-word," as one nonproliferation expert put it [1], experts have been quick to provide reasons why the Daiichi crisis will not be "the next Chernobyl."

Experts have noted several key differences in the design of the reactors in question, as well as in the government's reaction to the crisis:

1. Chernobyl's reactor had no containment structure.

The RBMK reactor at Chernobyl "was regarded as the workhorse of Soviet atomic energy, thrifty and reliable -- and safe enough to be built without an expensive containment building that would prevent the release of radiation in the event of a serious accident," The Guardian's Adam Higginbotham noted [2].

As a result, when a reactor exploded on April 26, 1986, the radioactive material inside went straight into the atmosphere [3].

Fukushima's reactors [4] are surrounded by steel-and-concrete containment structures [5]. However, as the New York Times reported Tuesday, the General Electric Mark 1 reactors at Fukushima have "a comparatively smaller and less expensive containment structure [6]" that has drawn criticism from American regulators. In a 1972 memo [7], a safety official suggested that the design presented serious risks and should be discontinued. One primary concern, the Times reported, was that in an incident of cooling failure -- the kind Fukushima's reactors are now undergoing -- the containment structures might burst, releasing the radioactive material they are supposed to keep in check.

At least one of Fukushima's reactors [4] -- No. 2 -- seems to have cracked, and has been releasing radioactive stream. The seriousness of this breach is still unclear [8], with a Japanese government official maintaining on Wednesday that the damage to the containment structure may not be severe.

2. Chernobyl's reactors had several design flaws that made the crisis harder to control. Most crucially, their cooling system had a "positive void coefficient," which means that as coolant water is lost or turns into steam, the reaction speeds up and becomes more intense [9], creating a vicious feedback loop.

Shan Nair [10], a nuclear safety expert who spent 20 years analyzing the consequences of Loss of Coolant Accidents like the one at Fukushima, discussed this factor on TIME's Econcentric blog [11]. Nair was a member of a panel that advised the European Commission on how to respond to Chernobyl. As he explained:

[Fukushima] can't be Chernobyl because the Boiling Water Reactors (BWRs) at Fukushima are designed differently than the High Power Channel-type Reactor (RBMK) reactor at Chernobyl. The RBMK was designed so that the hotter the core gets the greater the reactivity -- so you have a situation where you are in a vicious cycle and a race to an explosion. [Fukushima's] BWRs are designed in such a way that the hotter it gets the less radioactive the core gets so there is a self-shutdown type of mechanism. But the problem is that before you can get to a safe level you might have a complete meltdown. I believe that's what they are battling against now in Japan.

3. The carbon in Chernobyl's reactor fueled a fire that spewed radioactive material further into the atmosphere. Fukushima's reactors do not contain carbon, which means that the contamination from an explosion would remain more localized.

Dr. Colin Brown, director of engineering for the UK-based Institution of Mechanical Engineers [12], described another of the Chernobyl reaction's design flaws in a post on the Institution's website [13] explaining why it was "unlikely" that Fukushima "will turn into the next great Chernobyl with radiation spread over a big area." He wrote:

The reason why radiation was disseminated so widely from Chernobyl with such devastating effects was a carbon [graphite] fire. Some 1,200 tonnes of carbon were in the reactor at Chernobyl and this caused the fire which projected radioactive material up into the upper atmosphere causing it to be carried across most of Europe. There is no carbon in the reactors at Fukushima, and this means that even if a large amount of radioactive material were to leak from the plant, it would only affect the local area.

Britain's Chief Scientific Officer, Sir John Beddington [14], made a similar point about the localized nature of an explosion in a speech about Fukushima on Tuesday [15]:

In this reasonable worst case you get an explosion. You get some radioactive material going up to about 500 metres up into the air. Now, that's really serious, but it's serious again for the local area. It's not serious for elsewhere even if you get a combination of that explosion it would only have nuclear material going in to the air up to about 500 metres...And to give you a flavour for that, when Chernobyl had a massive fire at the graphite core, material was going up not just 500 metres but to 30,000 feet [about 9144 metres]. It was lasting not for the odd hour or so but lasted months, and that was putting nuclear radioactive material up into the upper atmosphere for a very long period of time. But even in the case of Chernobyl, the exclusion zone that they had was about 30 kilometres. And in that exclusion zone, outside that, there is no evidence whatsoever to indicate people had problems from the radiation.

One of the most pressing worries about Fukushima is that radiation might be spewed into the atmosphere not from reactors themselves, but from spent fuel rods exposed to the air [16] once the pool of water protecting them boils away. According to the Los Angeles Times, U.S. officials believe one of the spent fuel pools has been breached [17], potentially exposing 130 tons of uranium.

4. Unlike Chernobyl, however, a meltdown at Daiichi could end up contaminating the water table.

One troubling possibility that has received little attention is that a reactor meltdown could send radioactive material downwards until it reaches the water table, which could contaminate both water supply and crops. Discussing Daiichi on TIME's Ecocentric blog [18], Nair, the nuclear safety expert, noted:

If the entire fuel has melted the odds are it will go straight through the pressure vessel and therefore through the ground until it gets to the water table. Then it will cool down, but the problem is that the water table will start leaching actinides and fission products from the melted glob of fuel into the environment. So you will end up with some radioactive contamination of water supplies and ultimately crops and other products. That's a major problem because radioactive particles are much more dangerous when digested -- they cause internal irradiation of organs with resulting increased cancer risks...The severity of the water table risk depends on the local topography -- it depends on the depth of the water table, which itself moves up and down. I would imagine the water table is quite close to the surface right now because of all the flooding, which is not good.

At Chernobyl, fears that the radioactive material from the exploded reactor would reach the water table prompted a massive two-part project: first, to use liquid nitrogen to freeze the ground beneath the exploded reactor, and secondly, to build a shielding structure beneath the reactor. Although the effort exposed many miners to intense radiation [2], it was ultimately unnecessary.

5. Much of the public health impact of Chernobyl was the result of the Soviet government's attempt to cover up the crisis, rather than moving quickly to inform and protect the public.

In Japan, the government evacuated the 20 kilometers, or 12 miles, surrounding the Fukushima plant fairly quickly, and have continued to upgrade the warnings to citizens in the vicinity (although, according to the United States government, not quickly enough [19]).

That didn't happen at Chernobyl. In the sunny April morning after the explosion, the residents of the nearby town of Pripyat were left to go about their business. As the Guardian has noted, children went to school [2], an outdoor wedding was celebrated, and sunbathers went out to enjoy the good weather, as the plume from the exploded reactor continued to fill the air with radioactive particles.

One of the plant's employees, who had been away on business, returned home to find his wife outside in the garden, where she was paying no attention to the small pieces of graphite that had landed "on the petals of her wild strawberry plants." Before long, the sunbathers began to experience strange cases of nausea and vomiting. The town would not be evacuated until the next day. And it was only after heightened levels of radioactivity set off alarms at a nuclear plant in Sweden [19] that the Soviet government finally admitted publicly that something had gone wrong.

The delay and denial had serious implications, including an epidemic of thyroid cancer among about 6,000 people [20] exposed to radiation as children.

As the New York Times noted, this epidemic "would probably not have happened if people had been told to stop drinking locally produced milk, which was by far the most important source of radiation [20]."

(Russia distributed iodine tablets, as has Japan. But as we reported on Monday, these offer little protection [21] against ingesting contaminating food or milk.)

6. Emergency workers at Chernobyl took few precautions, and may not have been fully informed about the risks they were taking.

The "Fukushima 50 [22]" who stayed at the plant on Tuesday and Wednesday to keep containment efforts underway have been facing serious risks. But they have been taking precautions, the Times reported [23], including breathing through respirators, wearing full-body jumpsuits, and limiting their exposure time.

At Chernobyl, the Guardian wrote [2]:

[The firefighters] had had no protective clothing, or dosimetric equipment to measure radiation levels; the blazing radioactive debris fused with the molten bitumen, and when they had put the fires out with water from their hoses, they picked up chunks of it in their hands and kicked it away with their feet.... This heroic but utterly futile action took them closer to a lethal source of radiation than even the victims of Hiroshima...When they died two weeks later in Hospital No 6, Zakharov heard that the radiation had been so intense the colour of Vladimir Pravik's eyes had turned from brown to blue; Nikolai Titenok sustained such severe internal radiation burns there were blisters on his heart. Their bodies were so radioactive they were buried in coffins made of lead, the lids welded shut.

The Times noted that 28 of Chernobyl's emergency workers died [24] from radiation exposure within three months, and more than 100 developed radiation sickness.

Chernobyl's final toll [25] of deaths and injuries [26] is still a subject of fierce debate [3]. A 2005 Chernobyl Forum report [27], jointly produced by eight UN agencies and the governments of the Russian Federation, Ukraine, and Berlarus, concluded that up to "4,000 people could eventually die of radiation exposure" from Chernobyl, including 50 emergency workers who died of acute radiation syndrome, 15 children (as of 2005) who had died of thyroid cancer, and a projected total of "3940 deaths from radiation-induced cancer and leukemia" among emergency workers, evacuees, and residents of the most contaminated areas around Chernobyl. (The report noted that it's impossible to tell which cancer deaths in the region were specifically caused by Chernobyl radiation, only that there is an expected 3 percent increase.)
