Una lettura nuova della cittadinanza intesa non solo come insieme di tutele e garanzie giuridiche, ma come il processo del costituirsi consapevole dei soggetti, il cui sguardo cosciente e critico è in grado di dare consistenza alla comunità politicamente organizzata. Nella cittadinanza intesa come capacità di lasciare segni, non di consumare diritti, le donne sono state molto più presenti di quanto la storia abbia registrato
Origin of the mysterious Black Francolin (Francolinus francolinus) populations from greece and Northern Africa finally unveiled
No full textBiological collections host valuable specimens that may be key to addressing long-debated issues in different research fields, including conservation biology and historical biogeography. In this study, we use 200-year-old museums specimens to assess the contentious nature (i.e., the nativeness versus the allochthony) - of the black francolin (Francolinus francolinus, Phasianidae) populations once resident in Greece and northern Africa. This species, presently ranging from Cyprus and the Middle East to the Indian subcontinent, was deemed to have persisted in these Mediterranean regions until the first decades of the 19th century by some authors, yet this hypothesis had been firmly disproved by others due to the lack of supporting historical material and the fragmentary the literary evidence available. Nevertheless, we found four 200-year-old museum specimens - arguably the only ones still available from Greece and northern Africa - and sequenced their mitochondrial DNA Control Region. The comparison with conspecifics (n = 396) from the entirety of the historic and current species range unveiled that the new samples belong to previously identified genetic groups from the Near East and the Indian subcontinent. Other than denying the
occurrence of an allegedly native westernmost subspecies, our finding corroborates the role of the Crown of Aragon behind the circum-Mediterranean expansion of the black francolin, including Greece and northern Africa. Genetic evidence points to long-distance trade of these birds along the Silk Road to be sold in the Eastern Mediterranean first, and from there further west in Europe and northern Africa
Genetic characterization of game bird island populations: the conservation of the black francolin (Francolinus francolinus) of Cyprus
No full textThe release of exotic genotypes into the wild can lead to the extinction of local demes through the hybridization among distinct gene pools. This may occur between wild specimens and their domesticated relatives. Escaped pets represent a well-known pathway for the introduction of allochtonous resources, and island environments require major attention as they include small-sized and naïve populations that may be prone to extinction. We characterized the genetic make-up of the black francolin (Francolinus francolinus, Phasianidae) resident to Cyprus using microsatellite and mitochondrial DNA for the purpose of sustainable use and long-term protection of this game species. We collected 59 samples of specimens hunted in the districts of Nicosia and Paphos, while others (n=18) were obtained from birds of unknown origin. These had been imported to a pet-centre in Nicosia, the largest in the capital offering animals either for production or leisure purposes. Both genetic systems pointed to the occurrence of distinct wild district populations that could be treated as separate management units. The non-significant value of the inbreeding coefficient (FIS) computed for Nicosia and Paphos populations (-0.039 and -0.189, respectively: P>0.05) and the lack of evidence for recent genetic bottlenecks did not indicate a serious risk of over-hunting. The microsatellites revealed the birds in the pet-centre as highly genetically divergent with respect to the wild ones, the mtDNA pointed to their assignment to alien Asian subspecies once they were compared to141 sequences of allopatric francolins. We advised the Game & Fauna Service to consider law enforcement to ban the import, detention and sale of these subspecies to protect the black francolin population native to Cyprus. The results are discussed in the context of a bibliographic frame including the partridges of the genus Alectoris (Phasianidae) as a model group with reference to genetic characterization and conservation of game bird island population
Assessment of a sustainable energy chain designed for promoting the hydrogen mobility by means of fuel-cell powered bicycles
No full textThis paper aims to develop a sustainable energy chain that by means of a solar-driven electrolysis system produces renewable hydrogen used as fuel in fuel-cell-powered bicycles. The novel hydrogen bicycle model is the core of the bike-sharing program that is proposed in a Southern Italy tourist place. The sustainable energy chain development has required: i) the definition of the bike-sharing program based on some assumptions such as number of bicycles, number of routes, maximum number of trips per bike per day, mean driver weight, average cycling speed, etc.; ii) the analysis of the hydrogen bike performance; iii) the design of each involved energy sub-section such as the photovoltaic power plant, the hydrogen production system, the hydrogen storage unit and the hydrogen transportation and distribution section. The study has been conducted by implementing a design-sizing methodology. Results have highlighted that, according to the bike sharing program assumptions, the proposed sustainable energy chain consists of a 103 kWp PV power plant that, generating 129 MWh of electric energy, allows to produce 2190 kg of hydrogen by using an alkaline electrolyzer (16 kW). The bike sharing program, with 3772 km travelled in the selected area, contributes to reduce the greenhouse gas emission
Lettrice d’insieme. La fatica, la festa e i fatti di colonia nel Capodanno 2016,
No full textDa un fatto di cronaca accaduto a Colonia e non solo, dove la violenza sessuale sulle donne, che festeggiavano in piazza il capodanno 2016, ha preso le forme di un omogeneo comportamento, l’autrice reinterpreta la storia del patriarcato alla luce dei versi di Euripide, che già nelle Baccanti aveva legittimato contemporaneamente l’esclusione delle donne dalla festa, dalla città, ossia dalla vita pubblica e politica

On non-blocking properties of Parallel Delta Networks
No full textThis paper deals with the definition of a class of NxN interconnection networks called Parallel Delta Network (PDN). For this class of networks the non-blocking conditions are given. In particular, by means of the graph colouring technique, it has been proved that the minimum number of Delta subnetworks (L) necessary to provide the non-blocking property is L=nfS/21-1 where n is the size of the basic switching element and S the number of stages required by an NxN Delta network. A routing algorithm for the establishment of any permutation has been defined.
It operates for any value of n and shows a polynomial time
complexity equal to O(N3/2). Moreover, in case of the setup
of a single connection request, this algorithm assures a
time complexity equal to O(VN). This property makes it
well suitable to an asynchronous telecommunication
environment
A Multi-Language Comparison of Influences on Author Verification using Character N-Grams
No full textWe create a new multi-language corpus for author verification based on Wikipedia talkpages, and evaluate the influence that differences in topic and time have on character n-gram author profiles. Topic alignment between two texts is found to increase author verification precision, and an authors writing style is found to change over time, but not more significantly after 3 years than after 1 year.Information ArchitectureWISElectrical Engineering, Mathematics and Computer Scienc
