Are Internet protocol addresses personal data? The fight against online copyright infringement

Internet Protocol addresses [IP addresses] are central for Internet electronic communications. They individualize computers and their users to make the delivery of data packets possible. IP addresses are also often used to identify websurfers for litigation purposes. In particular, they constitute a key in the fight against online copyright infringement to identify infringers. However, it is a matter of dispute to know if IP addresses are personal data. In a review of relevant case law, the present paper seeks to identify when IP addresses are - or should be - considered as personal data. It suggests a contextual approach to the concept of personal data.     

The proximity paradox: the legislative agenda and?the?electoral success of ideological extremists

This paper presents a new approach to spatial models of legislative elections in which voters have preferences over the bundles of roll call votes implied by candidate locations rather than over the locations themselves. With such preferences, voters with single-peaked, symmetric preferences and perfect information can sincerely prefer a distant candidate to a more proximate candidate. Moreover, negative agenda control in Congress makes such preference orderings inevitable, so party agenda control can allow majority party extremists to defeat more centrist minority party candidates. The model has implications for theories of parties in Congress, and spatial modeling more broadly.
