Press, public opinion, constitutional transition: the thinking of the Italian liberal moderates (1814–1850)
No full textThis essay aims at offering a reconstruction of the main conceptual nodes at the center of the Italian liberal-moderates’ reflection on the role of public opinion and the media in the transition processes from the ancient regime to the constitutional state, with particular reference to the 1840s and to the caesura of 1848-49. It is a particularly stimulating perspective to focus on dynamics and problems regarding the relationship between media and politics, media and institutions, media and consensus building, media and mass mobilization, typical of today's world too. In the first place, the essay analyzes how the liberal-moderates reconstructed the role of the media, and the press in particular, in the delegitimization processes of the old regime institutions. Secondly, it outlines the consequences they drew from this with regard to the issues of both building political consensus and reshaping the forms of politics. Finally, the essay explains how the events of 1848-49 made mature their fear about the risks that these transformations could unleash precisely on the stability of modern constitutional institutions
Il Polibio di Leonardo Bruni
No full textAttraverso il riconoscimento dell'autografia bruniana di note marginali e interlineari nel codice di Polibio Vat. gr. 124, si individua in questo celebre manoscritto bizantino del sec. X il codice utilizzato da Leonardo Bruni a Firenze negli anni 1419-21 per la composizione dei suoi «Commentaria primi belli Punici». Per la prima volta è così individuato con sicurezza un codice greco utilizzato dall'umanista aretino, il più importante traduttore dal greco della prima metà del Quattrocento. Il contributo fa quindi luce su un momento decisivo del recupero di Polibio nell'Umanesimo italiano e pone nuove basi anche in relazione alla dibattuta questione della scrittura greca del Bruni
Unified Dark Matter models with fast transition
No full textWe investigate the general properties of Unified Dark Matter (UDM) fluid models where the pressure and the energy density are linked by a barotropic equation of state (EoS) p = p(ρ) and the perturbations are adiabatic. The EoS is assumed to admit a future attractor that acts as an effective cosmological constant, while asymptotically in the past the pressure is negligible. UDM models of the dark sector are appealing because they evade the so-called ``coincidence problem'' and ``predict'' what can be interpreted as wDE ≈ −1, but in general suffer the effects of a non-negligible Jeans scale that wreak havoc in the evolution of perturbations, causing a large Integrated Sachs-Wolfe effect and/or changing structure formation at small scales. Typically, observational constraints are violated, unless the parameters of the UDM model are tuned to make it indistinguishable from ΛCDM. Here we show how this problem can be avoided, studying in detail the functional form of the Jeans scale in adiabatic UDM perturbations and introducing a class of models with a fast transition between an early Einstein-de Sitter CDM-like era and a later ΛCDM-like phase. If the transition is fast enough, these models may exhibit satisfactory structure formation and CMB fluctuations. To consider a concrete case, we introduce a toy UDM model and show that it can predict CMB and matter power spectra that are in agreement with observations for a wide range of parameter values
