We present a system to extract, visualise and analyse inter-corporation relationships disclosed by public companies in their annual reports to the US Securities and Exchange Commission (SEC). In improving the transparency of these disclosures, we allow policymakers, analysts, investors and the general public to analyse these relationships at both the firm level and the industry level. Using…

Orr's work falls on one side of a marked divide separating rule-based theories from practice-focused research. From within the tradition of workplace studies (which show themselves intermittently susceptible to rule-based assumptions), Orr argues that his predecessors failed to see the sort of improvisation and bricolage central to his analysis, for want of looking. I claim, by contrast, that it…

This article examines three recent topics in copyright policy from an economic perspective: (i) term extensions, (ii) the orphan works problem, and (iii) mass digitization projects. Copyright term extensions will make it even more difficult to locate rights holders in the future than it is at present; however there are some recent legislative proposals to address this problem. Term extensions…

Democrats are well known for their "lousy bumper stickers," as Joe Klein puts it. As liberals wade through the semantics of "social security lockbox," "single payer," and other wonky locutions, the right has become harder,…

We propose an electronic voting machine architecture in which the voting user interface is prerendered and published before election day. The prerendered user interface is a verifiable artifact-an electronic sample ballot-enabling public participation in the review, verification, usability testing, and accessibility testing of the ballot. Preparing the user interface outside of the voting machine…

This essay considers positive, normative and political reasons for creating a map of the public domain and contiguous terrains. For far too many years, the public domain has either been invisible or been viewed in a negative way. By positively describing the contents of the public domain, it is possible to articulate normative reasons why the public domain is valuable to society. And by…

Should standards be eligible for copyright protection?

We propose a service differentiated peer selection mechanism for peer-to-peer media streaming systems. The mechanism provides flexibility and choice in peer selection to the contributors of the system, resulting in high quality streaming sessions. Free-riders are given limited options in peer selection, if any, and hence receive low quality streaming. The proposed incentive mechanism follows the…
