Metaphors we Lie by: our 'War' against COVID-19.

In this paper we discuss the influence of war as a metaphor in the context of the COVID-19 pandemic. After an introduction on the traditional analysis of the war metaphor, we address the social consequences of using this metaphor, a topic that has been widely debated with regard to public communication in the context of COVID-19. We pay particular attention to a theory that many intellectuals have raised: the possibility that the use of the metaphor in this context is harmful to a democratic society because it may lead citizens to accept limited civil liberties and authoritarian policies. After presenting the extensive literature on the use of the war metaphor before and during the COVID-19 pandemic, in the final section of the paper, we analyse experimental evidence of the effects of this metaphor. In the conclusion, we hint at open questions and suggest that the current evidence does not support claims of direct liberticidal influence.

Classification and distribution of freshwater microplastics along the Italian Po river by hyperspectral imaging.

In this work, freshwater microplastic samples collected from four different stations along the Italian Po river were characterized in terms of abundance, distribution, category, morphological and morphometrical features, and polymer type. The correlation between microplastic category and polymer type was also evaluated. Polymer identification was carried out developing and implementing a new and effective hierarchical classification logic applied to hyperspectral images acquired in the short-wave infrared range (SWIR: 1000-2500 nm). Results showed that concentration of microplastics ranged from 1.89 to 8.22 particles/m3, the most abundant category was fragment, followed by foam, granule, pellet, and filament and the most diffused polymers were expanded polystyrene followed by polyethylene, polypropylene, polystyrene, polyamide, polyethylene terephthalate and polyvinyl chloride, with some differences in polymer distribution among stations. The application of hyperspectral imaging (HSI) as a rapid and non-destructive method to classify freshwater microplastics for environmental monitoring represents a completely innovative approach in this field.

Zooplankton in Adriatic port environments: Indigenous communities and non-indigenous species.

The zooplankton community was analyzed in ten Adriatic ports as part of the port biological baseline surveys carried out within the framework of the BALMAS project. We provide the first inventory of resident zooplankton taxa and five detected non-indigenous zooplankton species (NIS), and their spatial and seasonal distribution patterns. Copepoda and meroplankton larvae, particularly of Mollusca, dominated the zooplankton in all sampled ports. We recorded a total of 76 indigenous copepod species and five NIS, among which Parvocalanus crassirostris detected in Sibenik and Rijeka ports and Oithona davisae in Venice port, are new for the Adriatic. All detected NIS were widely distributed within the recipient ports. Co-occurrences of NIS were observed in the ports of Venice, Bari, Ancona and Trieste. The results are expected to contribute to the quality of practical monitoring of zooplankton NIS and facilitate the synchronization of efforts in creating NIS-related policies for the Adriatic sub-region.
