    This paper summarizes the major findings of a three-year research project to investigate the Internet's impact on Russian politics, media and society. We employed multiple methods to study online activity: the mapping and study of the structure, communities and content of the blogosphere; an analogous mapping and study of Twitter; content analysis of different media sources using automated and human-based evaluation approaches; and a survey of bloggers; augmented by infrastructure mapping, interviews and background research. We find the emergence of a vibrant and diverse networked public sphere that constitutes an independent alternative to the more tightly controlled offline media and political space, as well as the growing use of digital platforms in social mobilization and civic action. Despite various indirect efforts to shape cyberspace into an environment that is friendlier towards the government, we find that the Russian Internet remains generally open and free, although the current degree of Internet freedom is in no way a prediction of the future of this contested space

    Propósito – Este artigo sintetiza os principais achados de um projeto de pesquisa de três anos para investigar o impacto da Internet sobre a política, a mídia e a sociedade russa. Metodologia/abordagem/design – Empregamos múltiplos métodos para estudar atividades online: o mapeamento e estudo da estrutura, das comunidades e do conteúdo da blogosfera; um análogo mapeamento e estudo do Twitter; a análise de conteúdo de diferentes fontes midiáticas, utilizando tanto abordagens automatizadas quanto abordagens baseadas em avaliação humana; e uma enquete com blogueiros; métodos esses expandidos por mapeamento de infraestrutura, por entrevistas e por investigações de contexto. Resultados – Constatamos a emergência de uma vibrante e diversa esfera pública interconectada, que constitui uma alternativa independente ao mais rigidamente controlado espaço midiático e político offline, e verificamos o uso crescente de plataformas digitais na mobilização social e na ação cívica. Implicações práticas – Apesar da existência de vários esforços indiretos para conformar o ciberespaço como um ambiente mais amigável ao governo, constatamos que a Internet russa permanece, em geral, aberta e livre, embora o atual grau de liberdade na Internet de forma alguma possa representar previsão acerca do futuro desse espaço contestado

The definitive version was published in Journal of Physical Oceanography 38 (2008): 880–895, doi:10.1175/2007JPO3750.1.The oceanic response to overflows is explored using a two-layer isopycnal model. Overflows enter the open ocean as dense gravity currents that flow along and down the continental slope. While descending the slope, overflows typically double their volume transport by entraining upper oceanic water. The upper oceanic layer must balance this loss of mass, and the resulting convergent flow produces significant vortex stretching. Overflows thus represent an intense and localized mass and vorticity forcing for the upper ocean. In this study, simulations show that the upper ocean responds to the overflow-induced forcing by establishing topographic β plumes that are aligned more or less along isobaths and that have a transport that is typically a few times larger than that of the overflows. For the topographic β plume driven by the Mediterranean overflow, the occurrence of eddies near Cape St. Vincent, Portugal, allows the topographic β plume to flow across isobaths. The modeled topographic β-plume circulation forms two transatlantic zonal jets that are analogous to the Azores Current and the Azores Countercurrent. In other cases (e.g., the Denmark Strait overflow), the same kind of circulation remains trapped along the western boundary and hence would not be readily detected.SK’s support during the time of his Ph.D. research in the MIT/WHOI Joint Program was provided by the National Science Foundation through Grant OCE04-24741.

    Network structure, brokerage, and framing: how the internet and social media facilitate high-risk collective action

    This thesis investigates the role of network structure, brokerage, and framing in high-risk collective action. I use the protest movement that emerged in Russia following falsified national elections in 2011 and 2012 as an empirical case study. I draw on a unique dataset of nearly 30,000 online documents and the linking structure of over 3,500 Russian Web sites. I employ a range of computational social science methods, including Exponential Random Graph Modeling, an advanced statistical model for social networks, social network analysis, machine learning, and latent semantic analysis. I address three research questions in this thesis. The first asks if a protest network challenging a hybrid regime will have a polycentric or hierarchical structure, and if that structure changes over time. Polycentric networks are conducive to high-risk collective action and are robust to the targeted removal of key nodes, while hierarchical networks can more easily mobilize protesters and spread information. I find that the Russian protest network has a polycentric structure only at the beginning of the protests, and moves towards a less effective hierarchical structure as the movement loses popular support. The second research question seeks to understand if brokered text is actually novel, and if that text is more novel in polycentric networks than in hierarchical ones. Brokers are the individuals or nodes in a network that connect disparate groups through weak ties and close structural holes. Brokers are advantageous because they have access to and spread novel information. I find that the text among nodes in brokered relationships is indeed novel, but that information novelty decreases when networks have a hierarchical structure. The last research question asks if a protest movement in a high-risk political setting can be more successful than the government at spreading its preferred frames, and within such a movement, whether moderate or extremist framing is more prevalent. I find that the opposition is far more effective than the government in spreading its frames, even when the government organizes massive counter protests. Within the movement, moderates are more likely to have their framing adopted online than extremists, unless violence occurs at protests. The findings suggest that movements should build flatter, more diffuse networks by ensuring that brokers tie together diverse protest constituencies. The findings also provide evidence against those who claim that authoritarian governments are more effective in shaping online discourse than oppositional movements, and also suggest that movements should advance moderate framing in order to attract a wider base of support among the general population.</p

    Public discourse in the Russian blogosphere: mapping RuNet politics and mobilization

    This paper&nbsp;analyses Russian blogs to discover networks of discussion around politics and public affairs. With funding from the MacArthur Foundation, the Berkman Center is undertaking a two-year research project to investigate the role of the Internet in Russian society. The study will include a number of interrelated areas of inquiry that contribute to and draw upon the Russian Internet, including the Russian blogosphere, Twitter, and the online media ecology. &nbsp;In addition to investigating a number of core Internet and communications questions, a key goal for the project is to test, refine, and integrate various methodological approaches to the study of the Internet more broadly. This working paper analyses the Russian blogosphere, with an emphasis on politics; it is the project\u27s first public research release. The authors&nbsp;analysed Russian blogs to discover networks of discussion around politics and public affairs. Beginning with an initial set of over five million blogs,&nbsp;the authors&nbsp;used social network analysis to identify a highly active ‘Discussion Core’ of over 11,000. These were clustered according to long term patterns of citations within posts, and the resulting segmentation characterized through both automated and human content analysis. Key findings include: Unlike their counterparts in the US and elsewhere, Russian bloggers prefer platforms that combine features typical of blogs with features of social network services (SNSs) like Facebook. Russian blogging is dominated by a handful of these “SNS hybrids.” While the larger Russian blogosphere is highly divided according to platform, there is a central Discussion Core that contains the majority of political and public affairs discourse. This core is comprised mainly, though not exclusively, of blogs on the LiveJournal platform. The Discussion Core features four major groupings: Politics and Public Affairs (including news-focused discussion, business and finance, social activists, and political movements) Culture (including literature, cinema, high culture, and popular culture) Regional (bloggers in Belarus, Ukraine, Armenia, Israel, etc.) Instrumental (paid blogging and blogging for external incentives) Political/public affairs bloggers cover a broad spectrum of attitudes and agendas and include many who discuss politics from an independent standpoint, as well as those affiliated with offline political and social movements, including strong ‘Democratic Opposition’ and ‘Nationalist’ clusters. The Russian political blogosphere supports more cross-linking debate than others we have studied (including the U.S. and Iranian), and appears less subject to the formation of self-referential ‘echo chambers.’ Pro-government bloggers are not especially prominent and do not constitute their own cluster, but are mostly located in a part of the network featuring general discussion of Russian public affairs. However, there is a concentration of bloggers affiliated with pro-government youth groups among the Instrumental bloggers. We find evidence of political and social mobilization, particularly in those clusters affiliated with offline political and social movements. The online ‘news diet’ of Russian bloggers is more independent, international, and oppositional than that of Russian Internet users overall, and far more so than that of non-Internet users, who are more reliant upon state-controlled federal TV channels. Popular political YouTube videos focus on corruption and abuse of power by elites, the government, and the police.

    This report uses a unique methodology that blends link analysis, term frequency analysis, and human coding of individual blogs to investigate the online discussions taking place across the Middle East and North Africa. Internet &amp; Democracy project director Bruce Etling and his team, with Morningside Analytics founder and Berkman affiliate John Kelly, and co-authors Robert Faris and John Palfrey, identified a base network of approximately 35,000 active blogs (about half as many as found in their previous study of the Persian blogosphere), created a network map of the 6,000 most connected blogs, and with a group of Arabic speakers hand coded 4,000 blogs. The goal for the study was to produce a baseline assessment of the networked public sphere in the Arab Middle East, and its relationship to a range of emergent issues, including politics, media, religion, culture, and international affairs. Whereas the previous study of the Persian blogosphere revealed a network organized primarily around political ideologies and topical issues, such as reformist and conservative politics, religion, and poetry, the Arabic blogosphere is organized primarily around countries. Moreover, personal life and local issues are the most important topics of discussion: most bloggers write mainly personal, diary-style observations, but when writing about politics, bloggers tend to focus on issues within their own country. Bloggers link to Web 2.0 sites like YouTube and Wikipedia (English and Arabic versions) more than other sources of information and news available on the Internet. The overall picture is one of country-based groupings of blogs focused on domestic issues
