    Leo Spitzer. Un profilo intellettuale

    No full text
    Il volume propone un ampio e articolato profilo intellettuale di Leo Spitzer (1887-1960), uno dei maggiori intellettuali del Novecento. Colmando una lacuna nella bibliografia italiana, il volume traccia un profilo ad ampio raggio del suo cinquantennale percorso di studioso e docente dalla vivacissima personalità. Tutte le discipline e le maggiori questioni attraversate da Spitzer vengono studiate e ripensate all'interno di un quadro complessivo, con particolare attenzione ai rapporti con la cultura italiana, da Croce a Pasolini

    Between public service and market: Portraying the bifront university in a platformized world

    No full text
    This paper contributes to the international debate on the changes affecting recruitment and orientation processes toward higher education. Based on qualitative research involving 19 Italian public universities, the study analyses the transformations in communication, recruitment and orientation activities within platformization and increasing institutional competition. Drawing on Bourdieusian conceptual categories, the analysis highlights how platformization and the changes triggered by the COVID-19 pandemic have opened new opportunities, which universities have interpreted and leveraged in diverse ways according to the evolving nature of the Italian university field as a space of material and symbolic differences. The primary outcome of these transformations is the reinforcement and crystallization of preexisting social and territorial inequalities, which is a historical characteristic of the Italian university system

    Deformed Wing Virus infection induces immunosuppression and gut dysbiosis in honey bees

    No full text
    Background: The global decline of honey bee health, driven by multiple stressors impairing immunity, threatens both natural and managed ecosystems. Deformed Wing Virus (DWV) is often found at high loads in collapsing colonies, associated with an immunosuppressive syndrome still poorly understood. This study investigates gut microbiota community patterns associated with different levels of DWV infection, an overlooked aspect which can contribute to the reduction of immunocompetence in infected honey bees. Results: We quantified DWV in nurse bees from the field and compared gut microbiota in individuals with high vs. low viral loads. We also examined microbiota changes in bees experimentally infected with DWV. In both cases, highly infected bees showed a decreased transcription level of dorsal 1-A, a consolidated molecular proxy of reduced immunocompetence in honey bees. Host immunosuppression was associated with a consistent gut dysbiosis, marked by a reduced relative abundance of beneficial genera such as Fructobacillus, Lactobacillus, and Apilactobacillus (Firmicutes, Bacilli), and a relative enrichment of Bartonella (Proteobacteria). Conclusions: These findings shed new light on host-pathogen interactions and will allow a targeted manipulation of honey bee gut microbiota to limit DWV infections, which strongly contribute to colony losses
