    Communication weaves the connections between new spatial relations, and creates new meanings and new imaginaries. The contemporary process of communication is giving substance to a model of society which identifies itself in the vast multimedia sea where space and cyberspace meet and combine in a dualism centred on place. In every area, there are forms and ways of life being mediated by social media, which impact on experience in the area and narration in recounting perception, acting on the imaginary and creating new expectations. This narration is present in every individual and is sustained by everyday actions. The scheme of content related by story, and more generally by forms of textualism, particularly texts mediated in virtual space, is increasingly incorporated into everyday actions. It is made up of shared fragments of ordinary life which are accessible to all. Online communication is becoming more pervasive thanks to a common experiential design helped by user-friendly interfaces and which link images of daily life to a series of images which the public recognise as common aesthetic forms . This uniformity of aesthetic experience is reached through pre-set background patterns and frames in terms of colour and layouts which can be found online all over the world. This uniformity impacts on individual sensitivity because through common frames, colours and codes it standardizes and captures ordinary and experiential individual content so that it can be channelled through online media. The more online information is considered important, in other words, independent, unstructured and spontaneous, the more individuals will incorporate it into their everyday experience. Online word of mouth is thus a substantial part of expressing of opinions in the daily life of networked users

    Magma chamber of the Campi Flegrei supervolcano at the time of eruption of the Campanian Ignimbrite

    A supereruption that occurred in the Campi Flegrei area, Italy, ca. 39 ka had regionaland global-scale environmental impacts and deposited the Campanian Ignimbrite (CI). We attempt to shed light on critical aspects of the eruption (depth of magma chamber, intensive pre-eruptive magma conditions) and the large-volume magma plumbing system on the basis of information derived from analyzing melt inclusion (MI) data. To achieve these aims, we provide new measurements of homogenization temperatures and values of dissolved H2O within phenocryst-hosted MIs from pumices erupted during different phases of the CI eruption. The MI data indicate that a relatively homogeneous overheated trachytic magma resided within a relatively deep magma chamber. Dissolved water contents in MIs indicate that prior to the eruption the magma chamber underwent radical changes related to differential upward movement of magma. Decompression of the rising trachytic magma caused a decrease in water solubility and crystallization, and trachytic bodies were emplaced at very shallow depths. The proposed eruptive model links portions of the main magma chamber and apophyses with specific eruptive units
