Asilo e cittadinanza europea alla luce della Carta dei diritti fondamentali

L'articolo analizza le norme della Carta dei diritti fondamentali dell'Unione europea, operando un confronto fra quelle riguardanti, in particolare, i richiedenti asilo e beneficiari della protezione internazionale, da un lato, e i cittadini europei, dall'altro, evidenziando analogie e punti di separazione

In merito al parere 2/13 della Corte di giustizia dell\u2019UE: qualche considerazione critica e uno sguardo de jure condendo

After a little more than one year from the request of the European Commission, the CJEU has given its Advisory Opinion on the accession agreement of the European Union to the ECHR. This article explores the content of Advisory Opinion 2/13: for each of the remarks of the CJEU, the content of the DRA is reported. In the light of this examination, the article offers two different keys of interpretation: one, critical, directed to the position which the CJEU expressed in its Advisory Opinion; the other, pro futuro, which essays to speculate on possible solutions for each of the objections made by the CJEU

On the Stopping Time of a Bouncing Ball

We study a simple model of a bouncing ball that takes explicitely into account the elastic deformability of the body and the energy dissipation due to internal friction. We show that this model is not subject to the problem of inelastic collapse, that is, it does not allow an infinite number of impacts in a finite time. We compute asymptotic expressions for the time of flight and for the impact velocity. We also prove that contacts with zero velocity of the lower end of the ball are possible, but non-generic. Finally, we compare our findings with other models and laboratory experiments.Comment: Submitted to archive for rational mechanics and analysi

Asserting the climate benefits of the coal-to-gas shift across temporal and spatial scales

Reducing CO2 emissions through a shift from coal to natural gas power plants is a key strategy to support pathways for climate stabilization. However, methane leakage in the natural gas supply chain and emissions of a variety of climate forcers call the net benefits of this transition into question. Here, we integrated a life cycle inventory model with multiple global and regional emission metrics and investigated the impacts of representative coal and gas power plants in China, Germany, India, and the US. We found that the coal-to-gas shift is consistent with climate stabilization objectives for the next 50 to 100 years. Our finding is robust under a range of leakage rates and uncertainties in emission data and metrics. It becomes conditional to the leakage rate in some locations only if we employ a set of metrics that essentially focuses on short-term effects. Our case for the coal-to-gas shift is stronger than previously found, reinforcing the support for coal phase-out
