    Il testo fa un bilancio delle evoluzioni del mondo editoriale nel primo quarto del XXi secolo, evidenziando l'inconsistenza della minaccia e-book, la nascita di molte piccole realtà editoriali, la contrazione del mercato editoriale, l'ibridazione dei generi di scrittura, la sfida attuale dell'IA

    Novel human coronavirus (SARS-CoV-2): A lesson from animal coronaviruses

    Full text link
    The recent pandemic caused by the novel human coronavirus, referrred to as severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), not only is having a great impact on the health care systems and economies in all continents but it is also causing radical changes of common habits and life styles. The novel coronavirus (CoV) recognises, with high probability, a zoonotic origin but the role of animals in the SARS-CoV-2 epidemiology is still largely unknown. However, CoVs have been known in animals since several decades, so that veterinary coronavirologists have a great expertise on how to face CoV infections in animals, which could represent a model for SARS-CoV-2 infection in humans. In the present paper, we provide an up-to-date review of the literature currently available on animal CoVs, focusing on the molecular mechanisms that are responsible for the emergence of novel CoV strains with different antigenic, biologic and/or pathogenetic features. A full comprehension of the mechanisms driving the evolution of animal CoVs will help better understand the emergence, spreading, and evolution of SARS-CoV-2

    The Boundaries of the Edible

    This paper offers a reflection on entomophagy in European countries with a focus on Italy, exploring the dynamics of cultural negotiation that the inclusion of insect-based food requires. Indeed, this practice is still far from meeting the shared, common sense and, as such, generates pathemic reactions often marked by disgust. In response, companies producing insect-based food must deploy complex rhetorical strategies either to present their products as acceptable or to make them so. The reflection concludes by highlighting the ideological component that is often hidden in discourses promoting insect-based food in Italy

    Volodymyr Zelensky: da leader a eroe

    Oggetto della riflessione è la figura di Zelensky –figura cardi- ne, certo, della guerra Ucraina-Russia, ma figura cardine anche di un fenomeno più ampio, che non riguarda direttamente la guerra: quel regime confusivo, che è specifico della post-verità, in cui non è dato distinguere tra reale e finzionale, perché tutto è viceversa collocato in un piano discorsivo in cui queste dimensioni sono indistinguibili. Al di là dell’interesse di Zelensky da questo punto di vista, come ca- so straordinario di collasso tra dimensione mediatico-spettacolare e di- mensione storico-empirica, nel saggio si approfondiscono, comunque, alcuni elementi salienti della sua leadership, una leader- ship secondo la lettura proposta radicalmente nuova rispetto a quella di qualsiasi altro leader della scena contemporanea

    At Different Speeds: Cancel Culture and Temporality

    No full text
    For a long time, Lotman’s theory of culture was read in the light of eminently spatial criteria and metaphors: boundaries, inner and outer space, spheres... However, Lotman’s contribution in considering the temporal dynamics that characterise semiospheres is fundamental. The points of attention, in Lotman's view of temporality, are in my opinion two: on the one hand, temporal rhythms differentiate and characterise the life forms (some life forms, such as fashion, have a faster rhythm; other life forms, such as folklore, have a slower rhythm of change). But beyond this, the different rhythms come into conflict with each other, because each semiosphere simultaneously hosts more than one life form. The contemporary topic of cancel culture is studied under this light, as a matter of temporal conflict

    Going Beyond Counting First Authors in Author Co-citation Analysis

    The present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed

    Lo spettacolo della guerra

    No full text
    Il testo presenta la specificità mediatica della guerra in Ucraina, una guerra che abbiamo seguito in diretta, su molti canali (fondamentale l'ingresso dei social) e che ha portato al centro dell'attenzione una cultura - quella Ucraina - fino al 2022 legata ad altri stereotipi. La guerra inoltre, sopraggiunta all'attenzione appena stava scemando l'attenzione mediatica per il covid, è intervenuta a modificare ancora la percezione dell'esperto, ponendo al centro del dibattito un tema (la guerra) apparentemente alla portata di tutti

    IDENTITÀ COLLETTIVE E VECCHI E NUOVI MEMORIALI

    No full text
    Quello che vorrei proporre nelle pagine che seguono è un contributo alla riflessione sulle identità collettive a partire da un genere preciso di forma simbolica: i memoriali. Assumo come punto di partenza uno studio di riferimento del ’900: quello di Benedict Anderson sulle Comunità immaginate (1983), per poi riflettere su alcuni tipi di memoriali del '900 e contemporanei: quello al milite ignoto, quelli ai caduti della Resistenza, quello alle vittime della Shoah, per finire coi memoriali grassroot alle vittime del Covid
