Frontiera e retoriche della migrazione: il caso della carta di Palermo 2015
2019
Questo lavoro propone una riflessione da una prospettiva geografica sul concetto di frontiera e sulle forme di spazialità che esso implica. Più in particolare, gli autori si concentrano sulle modalità attraverso cui la frontiera è continuamente (ri)definita a partire dalle retoriche (soprattutto pubbliche e mediatiche) che accompagnano le migrazioni considerate “clandestine” secondo le attuali norme europee. Le riflessioni vengono sviluppate a partire dal caso studio dell’immigrazione irregolare a Palermo, attraverso l’analisi della Carta di Palermo 2015, un documento approvato dalla Giunta comunale del capoluogo siciliano nel 2015 (e, successivamente, inviato alle massime cariche dello Sta…
To B or Not to B: Comparative Genomics Suggests Arsenophonus as a Source of B Vitamins in Whiteflies
2018
Insect lineages feeding on nutritionally restricted diets such as phloem sap, xylem sap, or blood, were able to diversify by acquiring bacterial species that complement lacking nutrients. These bacteria, considered obligate/primary endosymbionts, share a long evolutionary history with their hosts. In some cases, however, these endosymbionts are not able to fulfill all of their host's nutritional requirements, driving the acquisition of additional symbiotic species. Phloem-feeding members of the insect family Aleyrodidae (whiteflies) established an obligate relationship with Candidatus Portiera aleyrodidarum, which provides its hots with essential amino acids and carotenoids. In addition, ma…
Spatialité des frontières : géophilosophie d'après Michel Foucault et Gilles Deleuze
2012
The issue of borders is currently borne by political, economic and social emergency, which accounts for reverting to space-related questions, especially in the form of questioning limits, in social sciences, geopolitics and philosophy. The development of what is commonly known as globalization brings forth the idea that they might disappear in the mid- or short-term. It is therefore necessary to set up a concept and a typology of borders and their relation to space in order to decide on the possible reality of their disappearance.The first item goes thus : despite the apparently obvious homogeneity we get from immediate experience, space is a heterogeneous construction among whose elements …
Stochastic Frontiers Approach: an Empirical Analysis of Italian Environmental Spending
2012
Using the stochastic frontiers approach (SFA) on a panel of Italian regional data, this paper tries to analyse the optimal design of environmental spending. The main question is, so forth, studying centralization vs decentralization of a public economic function, such as the protection of the environment, in order to improve the welfare of a country. Empirical results on Italy are ambiguous: the changing from a centralized to a decentralized government, giving more autonomy to local units, does not highlight a clear improvement in regional economic performance.
