Mean-Field Game Modeling the Bandwagon Effect with Activation Costs
2015
This paper provides a mean-field game theoretic model of the bandwagon effect in social networks. This effect can be observed whenever individuals tend to align their own opinions to a mainstream opinion. The contribution is threefold. First, we describe the opinion propagation as a mean-field game with local interactions. Second, we establish mean-field equilibrium strategies in the case where the mainstream opinion is constant. Such strategies are shown to have a threshold structure. Third, we extend the use of threshold strategies to the case of time-varying mainstream opinion and study the evolution of the macroscopic system.

Three-dimensional display by smart pseudoscopic-to-orthoscopic conversion with tunable focus.
2014
The original aim of the integral-imaging concept, reported by Gabriel Lippmann more than a century ago, is the capture of images of 3D scenes for their projection onto an autostereoscopic display. In this paper we report a new algorithm for the efficient generation of microimages for their direct projection onto an integral-imaging monitor. Like our previous algorithm, the smart pseudoscopic-to-orthoscopic conversion (SPOC) algorithm, this algorithm produces microimages ready to produce 3D display with full parallax. However, this new algorithm is much simpler than the previous one, produces microimages free of black pixels, and permits fixing at will, between certain limits, the reference …
The Real World in a Geographical Imagery: World of Warcraft as Playful Cartography?
2017
World of Warcraft (WoW) is an extremely well-known and wide-spread virtual universe, populated by millions of people living, as of 2014, in 244 different countries, and so coming from different cultures. The game can be considered the final result of a half-century of growing interest in fantasy and virtual worlds; starting from Tolkien’s The Lord of the Rings. In the passage from book to videogame, fantasy has become an immersive experience that captures the player and forces him or her to revise their idea of how the world works. Everyone can read these worlds as simple games or, rather, through multifarious levels that show the connections between reality and virtuality. Our paper aims a…

Catherine Jagiellon, Queen Consort of Sweden: Counselling Between the Catholic Jagiellons and the Lutheran Vasas
2018
Catherine Jagiellon (1526–83), was a Catholic Polish-Lithuanian princess married to a Lutheran Swedish Prince, John Vasa, Duke of Finland and later King of Sweden. Her case provides important insights into the impact of confessional differences within a royal marriage of the sixteenth century and their consequences for counsel. The chapter highlights the significance of Catherine’s network of confidants, and the role of her entourage in providing political support. While she was not always a successful counsellor, evidence from her correspondence demonstrates that she was a careful manager of her self-presentation in a range of delicate situations.
Does a specific genetic background influence endurance or power-orientated phenotypes?
2012
The purpose of this study was to determine the probability of individuals having the “best” mitochondrial biogenesis related polygenic profile that could increase performance. We compared polygenic profile analyzing several polymorphisms on sixty professional italian soccer players, considered “power-oriented athletes” and thirty sedentary volunteers. Samples of venous blood were obtained by standard clinical procedures and anticoagulant-treated blood was used to prepare genomic DNA. The polymorphic sites were scanned using PCR-RFLP protocols with different enzyme. Furthermore, a cloted part of venus blood sample was used to obtain serum from which we analyzed total cholesterol, high densit…
Risk perception, knowledge, prevention, information sources and efficacy beliefs related to Covid-19
2020
Abstract Background Sars-Cov-2 is one of the latest examples of an emerging infectious disease challenging the world and it is the third case, in just two decades, of “spillover”. In light of the recent outbreak (Italy is in 2nd position), it is important to evaluate people risk perception and to support the Health Authority with effective communicative actions to avoid the spread of “infodemia”/alarmism. The aim of this study is a) to study levels of perceived threat, risk perception, severity and comparative vulnerability b) to compare risk perception with other communicable/not communicable diseases; c) provide information to increase awareness/ knowledge of the disease. Methods We perfo…
