The Networks and Complexity in Social Systems course commences with an overview of the nascent field of complex networks, dividing it into three related but distinct strands: Statistical description of large scale networks, viewed as static objects; the dynamic evolution of networks, where now the structure of the network is understood in terms of a growth process; and dynamical processes that take place on fixed networks; that is, "networked dynamical systems". (A fourth area of potential research ties all the previous three strands together under the rubric of co-evolution of networks and dynamics, but very little research has been done in this vein and so it is omitted.) The remainder of the course treats each of the three strands in greater detail, introducing technical knowledge as required, summarizing the research papers that have introduced the principal ideas, and pointing out directions for future development. With regard to networked dynamical systems, the course treats in detail the more specific topic of information propagation in networks, in part because this topic is of great relevance to social science, and in part because it has received the most attention in the literature to date.

In 'Privacy and Politics', Kieron O'Hara discusses the relation of the political philosophy of privacy to technical aspects in Web development. Despite a vigorous debate, the concept remains ambiguous, and a series of types of privacy is defined: epistemological, spatial, ideological, decisional and economic. Each of these has a different meaning in the online environment, and will be defended by different measures. The question of whether privacy is a right is raised, and generational differences in attitude discussed, alongside the issue of whether privacy should be protected in advance, via a consent model, or retrospectively via increased transparency and accountability. Finally, reasons both theoretical and practical for ranking privacy below other values (such as security, efficiency or benefits for the wider community) are discussed.

Building software for Web 2.0 and the Social Media world is non-trivial. It requires understanding how to create infrastructure that will survive at Web scale, meaning that it may have to deal with tens of millions of individual items of data, and cope with hits from hundreds of thousands of users every minute. It also requires you to build tools that will be part of a much larger ecosystem of software and application families. In this lecture we will look at how traditional relational database systems have tried to cope with the scale of Web 2.0, and explore the NoSQL movement that seeks to simplify data-storage and create ultra-swift data systems at the expense of immediate consistency. We will also look at the range of APIs, libraries and interoperability standards that are trying to make sense of the Social Media world, and ask what trends we might be seeing emerge.
