: The formation of issue-publics that relate to the UK National DNA Database.

The United Kingdom has a long tradition of collecting and storing DNA data for criminal identification purposes. The development of the UK National Criminal Intelligence DNA Database has been accompanied by public controversies. Building on recent developments in Science and Technology Studies on public engagement, we elaborate on the concept of emergent and co-produced issue-publics.

Innovating public participation methods: Technoscientization and reflexive engagement.

We reconstruct the innovation journey of 'citizen panels', as a family of participation methods, over four decades and across different sites of development and application. A process of aggregation leads from local practices of designing participatory procedures like the citizens jury, planning cell, or consensus conference in the 1970s and 1980s, to the disembedding and proliferation of procedural formats in the 1990s, and into the trans-local consolidation of participatory practices through laboratory-based expertise since about 2000. Our account highlights a central irony: anti-technocratic engagements with governance gave birth to efforts at establishing technoscientific control over questions of political procedure.
