Mercato delle idee e fake news. Note su un problema di esternalità negative nell’ambiente digitale
2023
The spread of fake news in the digital arena has put into question the traditional idea of the self-regulation of public debate: the well-known metaphor of “free market of ideas”. Because of the availability of digital media, the reduction of the overall cost in producing and disseminating false news has dramatically fallen. Everybody at any time can enter the public debate, even though with bad arguments. At the same time, the competition between traditional and digital media has produced an astonishing reduction of the average incomes of the professional journalists. This paper aims to bring to the fore the metaphor of the market of ideas, metaphor that has been used in the US for reducin…
Micromechanisms of load transfer in a unidirectional carbon fibre-reinforced epoxy composite due to fibre failures: Part 3. Multiscale reconstruction…
2008
International audience; This third article describes a multiscale process which takes into account the most important microscopic phenomena associated with composite degradation, including fibre fractures and interfacial debonding, overloading of fibres neighbouring a fibre break as well as viscoelastic behaviour of the matrix. The results have been used to accurately predict the macroscopic failure of unidirectional carbon fibre-reinforced epoxy and quantify damage accumulation in pressure vessels made of the same material. The approach described has allowed the acoustic emission activity resulting from fibres breaks to be evaluated and shown how the residual lifetimes of such vessels, whe…
One size does not fit all! New perspectives on the university in the social knowledge economy
2016
Universities face a tension from two urgent pressures they face, firstly to demonstrate that they deliver value for society in return for public investments, and secondly to demonstrate their responsibility by introducing strategic management to demonstrate to their funders that they meet their goals. In this special issue, we explore the ways in which these tensions play out in practice, as universities facing 'mission overload' in turn try to develop additional regional development missions, highlighting three findings. Firstly, there can be no one-size-fits all idea of a 'third university mission' alongside teaching and research because engagement is so context-dependent. Secondly, unive…
Machinery Failure Approach and Spectral Analysis to Study the Reaction Time Dynamics over Consecutive Visual Stimuli: An Entropy-Based Model.
2020
[EN] The reaction times of individuals over consecutive visual stimuli have been studied using an entropy-based model and a failure machinery approach. The used tools include the fast Fourier transform and a spectral entropy analysis. The results indicate that the reaction times produced by the independently responding individuals to visual stimuli appear to be correlated. The spectral analysis and the entropy of the spectrum yield that there are features of similarity in the response times of each participant and among them. Furthermore, the analysis of the mistakes made by the participants during the reaction time experiments concluded that they follow a behavior which is consistent with …
Video-assisted surgery: suggestions for failure prevention in laparoscopic cholecystectomy
2014
Background: Surgery differs from other medical specialties in its execution. It is often complex and includes considerable individual variations. Observing problems in operating theatres (OT) allows for the identification of system failures which should be defined for learning purposes to increase patient safety and enhance general safety culture within hospital organizations. This study evaluates a common video-assisted surgical procedure, laparoscopic cholecystectomy (LC) through failure analysis. The profile of the LC procedure and failure sources is presented. Methods: Data consisted video-observations and interviews concerning twelve LC operations performed at a day surgery unit. All o…
