Citizen participation in news
No full textThe process of producing news has changed significantly due to the advent of the Web, which has enabled the increasing involvement of citizens in news production. This trend has been given many names, including participatory journalism, produsage, and crowd-sourced journalism, but these terms are ambiguous and have been applied inconsistently, making comparison of news systems difficult. In particular, it is problematic to distinguish the levels of citizen involvement, and therefore the extent to which news production has genuinely been opened up. In this paper we perform an analysis of 32 online news systems, comparing them in terms of how much power they give to citizens at each stage of the news production process. Our analysis reveals a diverse landscape of news systems and shows that they defy simplistic categorisation, but it also provides the means to compare different approaches in a systematic and meaningful way. We combine this with four case studies of individual stories to explore the ways that news stories can move and evolve across this landscape. Our conclusions are that online news systems are complex and interdependent, and that most do not involve citizens to the extent that the terms used to describe them imply

A Response to Scott
No full textPower D. A response to Scott, Regional Studies. This paper deals with two main issues. First, it addresses the issue of how we tackle the status of the creative city discourse and how we should understand and react to policy in third-wave cities. Second, it discusses the issue of where we see the lines of stratification and division between people and workers in third-wave cities. This paper responds to some of the suggestions contained in the article by Allen J. Scott in this issue.</p
Market Power Assessment and Mitigation in Hydrothermal Systems
No full textThe objective of this work is to investigate market power issues in bid- based hydrothermal scheduling. Initially, market power is simulated with a single stage Nash-Cournot equilibrium model. Market power assessment for multiple stages is then carried through a stochastic dynamic programming scheme. The decision in each stage and state is the equilibrium of a multi-agent game. Thereafter, mitigation measures, specially bilateral contracts, are investigated. Case studies with data taken from the Brazilian system are presented and discussed.Game theory, Hydroelectric-thermal power generation, Power generation economics
