Do commodity assets hedge uncertainties? What we learn from the recent turbulence period?
2022
AbstractThis study analyses the impact of different uncertainties on commodity markets to assess commodity markets' hedging or safe-haven properties. Using time-varying dynamic conditional correlation and wavelet-based Quantile-on-Quantile regression models, our findings show that, both before and during the COVID-19 crisis, soybeans and clean energy stocks offer strong safe-haven opportunities against cryptocurrency price uncertainty and geopolitical risks (GPR). Soybean markets weakly hedge cryptocurrency policy uncertainty, US economic policy uncertainty, and crude oil volatility. In addition, GSCI commodity and crude oil also offer a weak safe-haven property against cryptocurrency uncer…
Impact of Perceived Stress and Immune Status on Decision-Making Abilities during COVID-19 Pandemic Lockdown.
2021
The ability to make risky decisions in stressful contexts has been largely investigated in experimental settings. We examined this ability during the first months of COVID-19 pandemic, when in Italy people were exposed to a prolonged stress condition, mainly caused by a rigid lockdown. Participants among the general population completed two cognitive tasks, an Iowa Gambling Task (IGT), which measures individual risk/reward decision-making tendencies, and a Go/No-Go task (GNG), to test impulsivity, together with two questionnaires, the Perceived Stress Scale and the Depression, Anxiety and Stress Scales. The Immune Status Questionnaire was additionally administered to explore the impact of t…
Incidence of long COVID-19 in people with previous SARS-Cov2 infection: a systematic review and meta-analysis of 120,970 patients
2022
The long-term consequences of the coronavirus disease 19 (COVID-19) are likely to be frequent but results hitherto are inconclusive. Therefore, we aimed to define the incidence of long-term COVID signs and symptoms as defined by the World Health Organization, using a systematic review and meta-analysis of observational studies. A systematic search in several databases was carried out up to 12 January 2022 for observational studies reporting the cumulative incidence of long COVID signs and symptoms divided according to body systems affected. Data are reported as incidence and 95% confidence intervals (CIs). Several sensitivity and meta-regression analyses were performed. Among 11,162 papers …
“Una visione poliprospettica sull’emergenza da coronavirus nei rapporti tra privati”: note introduttive
2021
Il contributo analizza in maniera poliprospettica i cambiamenti accelerati dalla pandemia da Covid-19 (digitalizzazione con tutti i suoi corollari: smart working, commercio on line, processo telematico e amministrazione digitale, etc.) e quelli che sono stati provocati da essa (la galoppante deurbanizzazione e il crollo del mercato immobiliare nei centri delle grandi capitali del mondo).
Effects of COVID19 pandemic on the Italian power system and possible countermeasures
2021
Abstract The paper analyses the dramatic effects of the first wave of the COVID-19 pandemic on the Italian power system, considering the impacts on load and generation, market issues and ancillary services provision. During the period between March and May 2020, the Italian scenario was considered as exemplary due to the large reduction of loads and thermal generation caused by the hard lockdown across the Country. Italy has experienced the most severe effects of pandemic in terms of increase of death rates and of pressure on the health system as well as severity of the countermeasures. As a domino effect, the total lockdown of one of the most industrialized countries in the world has creat…
Mobility Patterns and Mode Choice Preferences during the COVID-19 Situation
2022
The empirical research on the COVID-19 epidemic’s consequences suggests a major drop in human mobility and a significant shift in travel patterns across all forms of transportation. We can observe a shift from public transport and an increase in car use, and in some cases also increase of cycling and (less often) walking. Furthermore, it seems that micromobility and, more generally, environmentally friendly and comanaged mobility (including shared services), are gaining ground. In previous research, much attention was paid to the mode choice preferences during lockdown, or early stages of the SARS-CoV-2 situation. The blind spot, and aim of this work, is how long observed changes in mode ch…
Does Culture Matter? : Measuring Cross-Country Perceptions of CSR Communication Campaigns about COVID-19
2022
The COVID-19 pandemic has brought several challenges to businesses and societies. In response, many corporations have supported local communities and authorities in the management of the pandemic. Although these initiatives, which can be considered forms of corporate social responsibility (CSR), were highly coupled with explicit CSR communication campaigns, little is known about whether these campaigns were effective. Previous research indicates that culture can shape people’s perceptions of CSR initiatives and communications, suggesting that businesses pay attention to careful consideration of cultural norms for effective CSR communication. However, the COVID-19 pandemic as a new CSR setti…
Co-circulation of SARS-CoV-2 Alpha and Gamma variants in Italy, February and March 2021
2022
Background Several SARS-CoV-2 variants of concern (VOC) have emerged through 2020 and 2021. There is need for tools to estimate the relative transmissibility of emerging variants of SARS-CoV-2 with respect to circulating strains. Aim We aimed to assess the prevalence of co-circulating VOC in Italy and estimate their relative transmissibility. Methods We conducted two genomic surveillance surveys on 18 February and 18 March 2021 across the whole Italian territory covering 3,243 clinical samples and developed a mathematical model that describes the dynamics of co-circulating strains. Results The Alpha variant was already dominant on 18 February in a majority of regions/autonomous provinces (…
Dal corpo virtuale alle virtù del corpo (Atti del Convegno Nazionale APID® 2021)
2022
Nella Danza Movimento Terapia (DMT) vengono coinvolte più dimensioni interrelate: psicologica, emozionale, immaginativa, creativa, relazionale, espressiva, comunicativa, estetica. Fondamentale, data la complessità dei processi coinvolti, è garantire un setting; in DMT esso va inteso come un insieme di componenti stabili e riconoscibili che consento di creare uno “spazio extra-ordinario” protetto e intimo, connotato affettivamente. La relazione psicocorporea intersoggettiva, la significatività dello spazio, il setting presuppongono la presenza, la possibilità di scambi e contatti emozionali che sembrerebbero non poter prescindere dal trovarsi fisicamente insieme. La pandemia da Covid 19 ha c…
The Effects of Pandemic Restrictions on Public Health-Improvements in Urban Air Quality.
2022
The present study aims to provide evidence on the effects of pandemic curtailment measures on public health, targeting the changes in breathable air quality, within urban areas. The analyzed period covers the full impact of lockdowns in Europe in 2020. We used everyday data for each analyzed pollutant, NO2, SO2, CO, PM2.5 and PM10, from urban monitoring stations that provided real-time concentrations (provided by Copernicus Atmosphere Monitoring Service, Environmental Protection Agency repository and European Environment Agency map services) and satellite data (provided by NASA Orbiting Carbon Observatory 2). In the present study, the urban air quality was computed using a composite index t…
