The first part of the thesis gives a systematic overview and conceptual analysis of the literature on studying misinformation and disinformation in social media, with a special focus on research projects using large scale data obtained from Twitter and Facebook. The literature review gives a detailed overview of the scope of data collected by the various research projects; the means of accessing the data, which are rooted in the concrete socio-technical arrangement of the various platforms, and the type of analytical tools they apply. Furthermore, it also maps the various theoretical questions behind the research projects. The author of the thesis also gives his own definition of information manipulation and describes a conceptual model of information manipulation in the context of social media.
The second part of the thesis applies some of the insights from the literature review to a large Twitter data set collected during the monitoring of African elections. The analysis follows a qualitative approach and focuses on case studies created from specific incidents during the elections. Each of these incidents illustrates a special aspect of the problem of information manipulation in online social media.

The Community Broadband Investment Act, introduced in the Georgia legislature in 2012 and 2013 is a reflection of a broader national debate over the role of government investment in broadband infrastructure. The bill would limit local governments' ability to invest in broadband infrastructure for their communities because of arguments that government entry into the telecommunications sector crowds-out private competition, does not serve the public adequately, and lacks a comprehensive business model or best practices. A closer look at the history of utility regulation and various economic perspectives on the proper government role in utility provision reveals that government has had an extensive historical role in utility infrastructure investment and regulation, and several economic doctrines support the conclusion that government can be helpful in facilitating effective broadband service to their communities. Case studies of different models of municipal broadband networks in Georgia reveal that government entry can facilitate private sector competition, often provides quality service, and has a set of best practices. The success of municipal broadband reveals an evolution in the approach to telecommunications regulation from a regulated monopoly approach to a public-private cooperation approach which considers public participation with private entities on a dynamic scale. Government-entry into the broadband market was a rational decision for several Georgia communities due to their unique set of circumstances, and while municipal broadband may not be the answer to many communities' problems with meeting public demand, communities should be allowed to maintain flexibility in their decision-making about how to best serve their residents, effectively allowing them to decide which combination of public and private advantages they can leverage to meet the demand of their communities in relation to their unique local characteristics.
