The changing role of the local news media in enabling citizens to engage in local democracies

Using Leeds City Council in the United Kingdom as a case study, we analyse comparatively the changing role of local journalism in the public communications and engagement strategies of local government. Drawing on over 20 semi-structured interviews with elected politicians, Council strategists, mainstream journalists, and citizen journalists, the article explores perceptions of the mainstream news media's role versus new modes of communication in engaging and communicating with citizens. We evaluate the Council's perceptions of its online and offline practices of engagement with different publics, and focus in particular on their interactions with journalists, the news media, and citizen journalists. The article considers how moves towards digital modes of engagement are changing perceptions of the professional role orientations of journalists in mediating between the Council and the general public

New U-Pb and Rb-Sr constraints on pre-Arcadian tectonism in North Wales

A new U–Pb date of 615.2 ± 1.3 (2) Ma for the Twt Hill Granite, North Wales, contrasts with an Rb–Sr isochron age of 491 ± 12 (2) Ma from the same body. The latter age is thought to result from isotope resetting during regional low-grade metamorphism or fault reactivation. The Rb–Sr age also coincides with the onset of latest Cambrian to Early Tremadoc regression and is taken to reflect tectonic uplift prior to the Arenig overstep at around 478 Ma. It is proposed that this in turn reflects plate-scale processes along the contemporary peri-Gondwanan continental margin
