Introduction: The Impact of the COVID-19 Pandemic on the Agri-food Supply Chain
2022
The origin of the COVID-19 pandemic is still unclear, but the link with the presence in the food chain of wild animals for human consumption has been claimed as one of the possible sources of the so-called “spillover” of the virus. Food safety throughout the food chain, from field to fork, is one of the most critical issues of the food industry, and significant differences still exist from country to country concerning food production systems, postharvest management, trading, and retail organization. The effect of the pandemic has touched all steps of the food chain.
Impact of COVID-19 on aquaculture sector in Malaysia: Findings from the first national survey
2021
Abstract Malaysian aquaculture sector consists of 391,000 t of cultivated organisms produced per year with an economic value for over USD 700 million as estimated in 2019. The COVID-19 pandemic caused a large global human pandemic and it is currently ongoing, affecting profoundly Malaysian aquaculture, which is vital for seafood provision and security assurance. Thus, to increase our understanding about how the pandemic affects aquaculture sectors is crucial to design possible management measures both at local and national level. To do it, we designed a survey, starting in May 2020, consisting of 25 online questions to collect information about the impact of COVID-19 on the aquaculture sect…
A Phenomenological Study About the Effect of Covid-19 Pandemic on the Use of Teaching Resources in Mathematics
2023
In this contribution, we discuss phenomenological research related to a pilot study carried out by the Consortium of the MaTeK Horizon 2020 project during the 2020–21 academic year. The research aims to analyse the effects of the Covid-19 pandemic on the use of teaching resources in mathematics in five coun- tries. A questionnaire made of seven questions was administered to a data sample made of teachers of all grades. The answers coming from the questionnaire were quantitatively and qualitatively analysed. Closed-ended questions were analysed by using a clustering methodology called k-means. Open-ended questions were qualitatively analysed. The results show that almost all the teachers are…
La città di Alphabet. Architettura per prosumers.
2021
Attraverso alcuni aspetti salienti dell’ideazione, della produzione e dell’opposizione al progetto del Toronto Quayside di Sidewalk labs, l’articolo discute l’influenza delle infrastrutture digitali per l’informazione sul progetto della casa e del quartiere. L’ampliamento delle attività svolte da remoto nello spazio domestico, enfatizzato dal quotidiano della pandemia da Covid 19, costituisce per gli oligopolisti planetari degli urban data come Alphabet un utile volano pubblicitario e un acceleratore. La fusione dei nuovi vessilli della tecnoemancipazione e della sostenibilità in ipotesi sperimentali che mirano a costruirsi sia per intero che per parti realizza un nuovo orizzonte in cui lo …

Nanofibrous Polymeric Membranes for Air Filtration Application: A Review of Progress after the COVID‐19 Pandemic
2023
Air pollution is one of the major global problems causing around 7 million dead per year. In fact, a connection between infectious disease transmission, including COVID-19, and air pollution has been proved: COVID-19 consequences on human health are found to be more severe in areas characterized by high levels of particulate matter (PM). Therefore, after the COVID-19 pandemic, the production of air filtration devices with high filtration efficiency has gained more and more attention. Herein, a review of the post-COVID-19 pandemic progress in nanofibrous polymeric membranes for air filtration is provided. First, a brief discussion on the different types of filtration mechanism and the key pa…
COURAGE at CheckThat! 2022: Harmful Tweet Detection using Graph Neural Networks and ELECTRA
2022
In this paper we propose a deep learning model based on graph machine learning (i.e. Graph Attention Convolution) and a pretrained transformer language model (i.e. ELECTRA). Our model was developed to detect harmful tweets about COVID-19 and was used to tackle subtask 1C (harmful tweet detection) at the CheckThat!Lab shared task organized as part of CLEF 2022. In this binary classification task, our proposed model reaches a binary F1 score (positive class label, i.e. harmful tweet) of 0.28 on the test set. We demonstrate that our approach outperforms the official baseline by 8% and describe our model as well as the experimental setup and results in detail. We also refer to limitations of th…
Ingiustizia del danno da covid
2022
Il capitolo sollecita una riflessione sul ruolo che, nell’ambito di un contesto di danni di massa, può di fatto rivestire l’istituto della responsabilità civile, le sue funzioni, e i suoi limiti. Muovendo dagli aspetti rilevanti del fenomeno pandemico nella prospettiva del diritto della responsabilità civile e dalla corretta individuazione dei criteri che presiedono alla formulazione del giudizio di responsabilità, l’indagine si concentra sul tema dell’ingiustizia del danno, quale snodo centrale per l’affermazione di una responsabilità civile. Che vi sia un danno, anzi diverse tipologie di danno, da Covid-19 è indubbio, non altrettanto certo e oggetto di analisi è, invece, se questi danni s…
La Cassa integrazione guadagni in deroga alla prova del Covid-19
2020
Nel contesto della grave crisi epidemiologica determinata dalla diffusione del Covid-19, il saggio si concentra sui principali interventi del Governo in materia di ammortizzatori sociali. Vengono analizzate le misure adottate per il sostegno di famiglie, lavoratori e imprese, mettendone in luce novità - determinate dallo stato di emergenza - e criticità. Specifica attenzione è dedicata allo strumento della Cassa Integrazione in deroga. In the context of the serious epidemiological crisis caused by the spread of Covid-19, the essay focuses on the main interventions of the Government about the social shock absorbers. The measures taken to support families, workers and businesses are analysed,…
Covid-19 e salute e sicurezza nei luoghi di lavoro: la prospettiva intersindacale
2020
Il saggio analizza la risposta dell’ordinamento intersindacale alla emergenza epidemiologica da Covid-19 in materia di salute e sicurezza nei luoghi di lavoro attraverso una disamina del Protocollo del 24 aprile 2020, e delle prime attuazioni a livello di categoria ed aziendale. Tecnicismi a parte, l’articolo sottolinea come le misure pattuite dalle parti sociali specificano ed integrano gli obblighi inderogabili e generali di legge in materia di salute e sicurezza. The essay focuses on the meausures undertaken by social partners to cope with Covid-19 having regard to health and safety in the workplace, throughout an analisis of interconfederal, national and company agreements. The article …
