Interpreting risks through the geographical identity: the importance of local perception in defining global vulnerability
No full textIf the perceived risk does not correspond to the real risk, what is risk? This paper aims to study the concept of perception and how it influences vulnerability to disasters. In particular, the discussion starts with the assumption that risk globalization has amplified the role of perception, reducing emotional distances. This makes it difficult to have a real perception of global risks, and it favours the distortion of their narrative. As discussed at considerable length in the literature, different cultural groups perceive environmental crises in different ways. This happens because of the weight that these groups’ cultural identities have in their level of perception. However, different levels of perception do not just result in low or high capacity to respond to emergencies; rather, they give rise to different ways of interpreting how to deal with risks. This paper focuses on the case of Madeira Island in particular. During the “Riscos naturais e comunidade local. Construir a resiliência através da participação” seminar, data on local perceptions was collected with the aim of understanding the level of disaster resilience on the island. The workshop was a moment of knowledge-sharing between scientists and the community. The results highlighted a certain lack in community identity as one of the main factors to be considered
Teodoro Bonati e i suoi corrispondenti veneti
No full textTeodoro Bonati (1740-1820) fu uno dei protagonisti della scienza e della tecnica in Italia nella seconda metà del Settecento e nel periodo napoleonico, soprattutto nel campo dell'idraulica, tradizionalmente coltivata a Ferrara per le esigenze del territorio. Bonati fu anche un valente cultore delle matematiche, favorito dalla frequentazione di Gianfrancesco Malfatti, professore di matematica nella stessa Università di Ferrara dove Bonati ricopriva la cattedra di idrostatica. In questo lavoro sono esaminati i rapporti di Bonati con gli scienziati veneti, alla luce dei temi trattati nel suo ampio carteggio. Il dibattito scientifico sul "caso irriducibile" delle equazioni cubiche che animò gli ambienti scientifici padovani trova eco nella corrispondenza con Antonio Maria Lorgna, Giambattista Nicolai, Vincenzo Chiminello: la polemica che ne seguì è illustrata nel primo paragrafo e vi si riferiscono alcune lettere pubblicate in appendice. La reciproca interferenza attraverso i fiumi fu da sempre motivo di discussione tra veneziani e ferraresi, e l'idrodinamica e l'idraulica pratica sono i temi principali delle lettere scambiate con Antonio Maria Lorgna (34) e Angelo Querini. Nel secondo paragrafo è illustrata in particolare la partecipazione di Bonati alla polemica sul Brenta, mentre alla figura e ai rapporti con Simone Stratico e alla partecipazione alle commissioni idrauliche del periodo napoleonico è dedicato il terzo paragrafo. Segue un'appendice in cui sono pubblicate sette lettere di Bonati a G.B. Nicolai, V. Chiminello, F.M. franceschinis, A. Zendrini, A. Artico, una lettera di G.B. Nicolai e tre di S. Stratico a Bonati
Resilientscapes: Perception and Resilience to Reduce Vulnerability in the Island of Madeira
No full textAbstractThis paper intends to discuss landscape resilience as a way of reducing disaster risk in the island of Madeira. Maderia is a Portuguese Macaronesian island that is located in the Atlantic Ocean and frequently affected by natural hazards.Here, the concept of resilience is discussed as a dichotomous and place-based concept and as a way of achieving sustainability, sustainability being one of the main solutions for climate change. This paper will discuss the complexity of defining “resilience”, the contradictions involved in its use and its positive and negative applications.In order to make resilience an operative concept, it is investigated within landscape research, in which landscape is considered to be the result of human and natural actions and their interaction. Here, landscape is considered as a holistic, place-based, bottom-up concept that can be used as a unit of measure for community resilience.As a consequence of the kind of relationship that a community builds with the landscape in which it lives, we can encounter different kinds of lansdscapes: riskscapes, hazardscapes, resilientscapes, sustainable landscapes, etc. These landscapes are investigated in the context of the island of Madeira in order to identify the resilient actions of its community.To conclude, today, Madeira is a riskscape and often a hazardscape. The most recent incidents were the fires of 2013 and the flash flood of 2010, which was one of the worst events in the history of the archipelago. However, the first signs of resilience have been identified, which represent interesting examples of increasing awareness in both top-down and bottom-up ways

No full textFlux tubes and string breaking in three dimensional SU(2) Yang-Mills theory
No full textWe consider the three dimensional SU(2) Yang-Mills theory with adjoint static color sources, studying by lattice simulations how the shape of the flux tube changes when increasing the distance between them. The disappearance of the flux tube at string breaking is quite abrupt, but precursors of this phenomenon are present already when the separation between the sources is smaller than its critical value, a fact that influences also some details of the static potential
