Japan's massive earthquake and tsunami three weeks ago and the challenging recovery process continue to make news headlines around the world. It is difficult to separate fact and reasonable speculation about the future from the terror-filled coverage about radiation leaking from the Fukushima nuclear complex. In an effort to make sense of recent events, the Walter H. Shorenstein Asia-Pacific Research Center (Shorenstein APARC) convened a panel of experts for a discussion about the possible future implications arising from this complex and emotionally charged situation for Japan's energy policy, economy, and politics.

Addressing an audience of one hundred students, faculty, and members of the general public on March 30, Shorenstein APARC associate director for research Daniel C. Sneider expressed the center's deep sympathy for those affected by the natural disasters and its profound admiration for the way in which the people of Japan are dealing with the aftermath. Members of the panel echoed these sentiments throughout the event.

Michio Harada, Deputy Counsel General at the Consulate General of Japan in San Francisco, cited official government figures indicating that, as of March 28, twenty-eight thousand people were dead or missing and one-hundred-and-eighty thousand people were still in evacuation shelters. Faced with such staggering figures, Japan remains in a rescue and recovery phase, he said, but is receiving a tremendous amount of global support. More than one hundred and thirty countries have provided financial assistance, and eighteen countries and regions have sent rescue teams. Collective public spirit is currently very strong, Deputy Counsel Harada emphasized. Japan's challenge moving forward, he suggested, will be to adopt pragmatic measures to fund reconstruction projects in the areas destroyed or damaged by the natural disasters.

Understanding the situation at the Fukushima nuclear power facility and the information circulating about the potential health risks of radiation exposure is complicated, stressed Siegfried S. Hecker, co-director of the Center for International Security and Cooperation. He described the intricate design and structure of the reactors and outlined the sequence of events up to the present, explaining the immediate, crucial challenge of continuing to cool the reactors and deal with the leakage of radiation from them. While there are definite and potentially very serious health threats from radiation exposure and contamination, Hecker said, fear and stress about the situation could also negatively affect mental and physical wellbeing. It is too soon to know the long-term implications for energy policy in Japan and other countries, he suggested, emphasizing the significance of learning from this experience in order to improve any future use of nuclear power.

Robert Eberhart, a researcher with the Stanford Program on Regions of Innovation and Entrepreneurship, proposed that the global supply chain is flexible enough to absorb any manufacturing disruptions in Japan. He noted that in the past twenty years most of Japan's heavy manufacturing has moved overseas, and that the components made there are a comparatively less significant part of the supply chain. In terms of the overall impact on Japan's economy, Eberhart suggested that the net effect on the GDP would be neutral over the next two years, explaining that the imminent loss of business and investment in some areas would be offset by the growth of firms involved in the reconstruction process.

Phillip Lipscy, a center fellow at the Freeman Spogli Institute for International Studies and an assistant professor with the Department of Political Science, stated that events and immediate needs during the early stages of reconstruction may have long-term affects on policymaking and the government structure in Japan. For example, the continued use of nuclear energy—a relatively clean and efficient source of power accounting for 30 percent of Japan's total energy consumption—will face public opposition due to rising concerns about safety and pressing energy needs. In addition, while Prime Minister Naoto Kan's prompt response after the natural disasters helped boost popular sentiment for him and the Democratic Party of Japan (DPJ), how they fare in the long term—especially with regard to the DPJ's relationship with the opposition Liberal Democratic Party and reconstruction-related modifications to its key economic policies—remains to be seen, Lipscy said.

Sneider closed the event with a comparison between the events in Japan and the April 2010 Gulf of Mexico oil spill, pointing to criticism that the Obama and Kan administrations have received for not regulating large corporations closely enough. A prompt resolution to the dangerous—and contentious—situation at the Fukushima nuclear complex is the most immediate concern, and one that will help foretell the long-term political implications for Japan's government, he concluded.

Although there is still a long road ahead in Japan—especially until the accident at Fukushima's nuclear reactor is contained and the actual after-effects of radiation are better understood—the underlying message during the panel discussion was that Japan will indeed recover and that the terrible events of the past weeks have brought people—and even the competing political parties—closer together.

Los Que Se Quedan (Those Who Remain) is the powerful story of nine Mexican families who cross the U.S. border in search of a better life and those left behind. In this moving story, the families share their hope and fears. The film has won many film festival awards, including Los Angeles, Biarritz, Woodstock, and Guadalajara. After the film, Beatriz Magaloni, Director of the Program on Poverty and Governance in Latin America, and Carlos Hagerman, the film's co-director, engaged in discussion with the audience.

Bandwidth connectivity is extremely low in many parts of the world, often delaying or even preventing people from accessing information. Although connectivity has increased by a factor of 10 or 15 over the last decade, average webpage size and number of objects has simultaneously increased by a factor of 60. This has resulted in what Subramanian terms an "unusable web"; the addition of video, audio and images has created huge web pages that take minutes or even hours to load in low connectivity worlds.

In his talk, Subramanian describes a range of techniques that he and his colleagues are developing to enhance information access in three scenarios of poor connectivity. These techniques illustrate the type of technologies being devised by a new group in Computer Science termed "Computing for Development." The focus of this group is on the design, implementation and evaluation of new computing innovations that enable global social and economic development. Since first world technology can often be a bad fit, this group instead seeks technologies that are locally appropriate, cost-effective, and easy to use.

The first low-connectivity scenario Subramanian discusses is that facing rural mobile users, who rely on low-end mobile devices and can thus only access voice and SMS services. To address the massive need for SMS services for this scenario, Subramanian and his colleagues have developed an SMS-based protocol stack for mobile applications that makes it possible to compress large quantities of information. The so-called UjU stack enables the compression of information into a 140-byte stack, while an affiliated UjU Create App interface enables anyone to create their own apps and forms. These forms are essentially turned into structured records (tables) that can be filled out and transmitted through a short message on a mobile phone. To date, UjU has already been used for microfinance applications in Mexico, mobile health data collection in India, and other applications in Ghana. Subramanian and his colleagues are also rolling out a live SMS search engine in Kenya and a data-over-GSM voice stack to support data connectivity over cellular voice.

Shared low bandwidth networks present a second low-connectivity scenario. In this scenario, an example of which might be a school where 2 Mbps of connectivity is used by 400 students, Subramanian suggests that a completely new Web architecture is needed. He and his colleagues have deployed an early version of such a system called Rural Café User Interface. Typically, a web browser sends dozens of requests when it is loading a particular page, since each site draws content from various sources and advertisers. Rather than being able to attempt to load as many windows and pages as possible, which results in even slower access, every user in Rural Café has a queue of what their search requests are. Users can search for anything at any point, but the interface acts as a planning tool by reporting how long (in seconds or minutes) the user would have to wait to load any particular site. The queue is persistent, so it doesn't change depending on how many new windows users try to open. This system is already being deployed in a few schools and universities in Kenya and India.

The third scenario is that of schools that have computer access, but no connectivity. To address this problem, Subramanian proposes the use of "vertical search engines" or contextual information portals that deliver a vertical slice of the Web in a hard-disk and provide an offline searchable and browse-able Internet. The portals are locally searchable and composed of many web-based services. Since the portals allow the user to search the local cache for the information they need rather than the URLs themselves, many local requests can be handled without browsing, supposing the local cache is strong and based on local interests and content. This is a good tool for either improving download times for people who have limited connectivity, or for enabling access for information for people without any connectivity at all. So far, the system has been piloted as an information tool for students and teachers in five schools with computers but no connectivity around Nairobi, Kenya.

The first Liberation Technology seminar of the winter quarter on January 6, featured Jonathan Zittrain, Professor of Law at Harvard Law School and co-founder of the Berkman Center for Internet & Society at Harvard University. Zittrain focused his talk entitled, Minds for Sale, on the variety of online platforms that harness the wisdom of crowds today, and closed with a discussion of the implications of these platforms. Categorizing these new tools by the breadth of their user base, Zittrain began by describing the platforms that pay the most money per task, require the most skill, and subsequently have the least participation. Key examples of these platforms are listed below, and organized by their decreasing level on skill.

•  Xprize Foundation attempts to prompt radical breakthroughs through competitions for large quantities of prize money.
• InnoCentive creates a marketplace between engineers and scientists to encourage innovation.
• LiveOps, which bills itself as a contact center cloud, has developed a large set of independent contractors who are designated specific tasks when they sign in to the site. They may be assigned to answer calls placed to a restaurant or emergency hotline or to make political calls on behalf of Liveops clients.
• Samasource offers "dignified digital work for women, children and refugees" located in developing countries.
• Amazon Mechanical Turk (also known as Artificial Artificial Intelligence) allows users to participate in anonymous, minimally paid tasks. These tasks can be submitted by any party and are highly disaggregated among hundreds or thousands of users, each of whom receives a payout of between approximately one to fifteen cents for completing the task.
• Soylent, which calls itself "a word processor with a crowd inside" embeds workers from Mechanical Turk into Microsoft Word. When users install the site's Shortn add-in into Microsoft Word, they can use the tool to have written samples shortened in two minutes. In order to achieve this, the written sample is disaggregated by paragraphs, and each paragraph is shortened within two minutes by a "Turker"-a user who accepts the task on Mechanical Turk.
• Microtask enables disaggregating previously sensitive data to be work processed from a scanned image. The ultimate goal of this group is to put distributed work into video and computer games. For now, they disaggregate larger tasks into two-second tasks that can be distributed across a crowd.
• Games With A Purpose (GWAP) has a game-like platform designed to get users to complete disaggregated tasks for virtual points, rather than for actual remuneration. One of its more popular activities quickly attracted 23,000 players who contributed 4.1 million labels to images they were presented with in The ESP Game. Many players routinely play more than 20 hours a week.

Next, Zittrain moved on to offer some additional examples, hypothetical scenarios and questions that highlight some of his own concerns about the potential of these technologies. One key question is whether this market may be too efficient at linking up solvers and payers, if certain tasks are not in fact beneficial for society. After all, it was highly contentious when Texas governor Rick Perry set up video cameras on Texas' border with Mexico and invited people to watch the video feeds and report if they saw anything suspicious. Similarly, a site called InternetEyes allows users to watch video feed from CCTV cameras in the UK for free, offering the chance to "earn reward money, have a chance at reducing crime, and potentially become a hero and save lives," instead of actual compensation.

In another example, the University of Colorado Police Department recently offered a $50 reward for identification of students shown to be smoking marijuana in photos from a large April 20 gathering. Hypothetically, the Iranian government could use Turkers to identify Iranian protestors through national ID photographs in the very same way; by Zittrain's calculations, this task could be disaggregated and carried out quickly at a cost of only $17,000 per protester identified.

Another cluster of issues relates to the use of anonymous users to carry out disaggregated tasks that may have the effect of exerting influence on others. For example, Turkers were recently offered the opportunity to write a positive 5 out of 5 review for a product on a website, which hundreds accepted and completed for a few cents at a time. Users on SubvertandProfit.com are paid to "Like" something on Facebook, "Digg" something, or show their approval of a site or product via some other social network. The users are remunerated for their effort, and the site also profits. Taking this a step further, these platforms also enable users to pay people to evince opinions on legislative issues they do not actually care about. For example, health insurers were recently caught paying Facebook gamers virtual currency to oppose the health reform bill. By enabling any task to be disaggregated and monetized, these new platforms can have highly controversial and unethical implications.
