Climate change impact on extrinsic and intrinsic competition between egg parasitoids
2012
Climate changing is a real phenomenon and the last decade was the warmest decade ever. The impact of climate change on animal communities is complex, affecting species interactions in all trophic levels, in different ways and in different bio-geographic zones. Here we will discuss about the possible effects of climate changes in shaping the competition between egg parasitoid species to consume the same hosts. Egg parasitoids are important biological control agents due to their ability to kill the pest before the crop-feeding stages emerge. Competitive effects can be divided in “extrinsic competition”, the indirect interactions between adult females searching for hosts, and “intrinsic compet…
Stipa valdemonensis (Poaceae), a new species from Sicily
2012
A new species of Stipa, endemic to Sicily, is here described and named Stipa valdemonensis. The new taxon is related to S. crassiculmis. Owing to the small number of individuals observed, in few restricted localities only, it is assigned the IUCN threat status “vulnerable”
$N$ identical particles and one particle to entangle them all
2017
In quantum information W states are a central class of multipartite entangled states because of their robustness against noise and use in many quantum processes. Their generation however remains a demanding task whose difficulty increases with the number of particles. We report a simple scalable conceptual scheme where a single particle in an ancilla mode works as entanglement catalyst of W state for other $N$ separated identical particles. A crucial novel aspect of the scheme, which exploits basically spatial indistinguishability, is its universality, being applicable without essential changes to both bosons and fermions. Our proposal represents a new paradigm within experimental preparati…
Multi-parametric GIS analysis to assess gully erosion susceptibility: a test in southern Sicily, Italy
2011
: A GIS-analysis was carried out in a test basin of southern Sicily, the Magazzolo River basin, in order to assess susceptibility conditions to gully erosion phenomena. The linear density of ephemeral and permanent gullies computed within each class of nine environmental variables was used to generate a gully erosion susceptibility map for the area. A validation procedure carried out in order to test the reliability of the adopted method highlighted a clear correlation between the occurrence of gullies and the computed susceptibility levels

A visual framework to support collaborative coding activities
2019
In this paper, we present a framework named SIRENE, a Web-based visual programming environment, where teachers and students can collaboratively interact, using a flexible and versatile definition of visual programming code instead of pre-established rules. After the description of the architecture of the SIRENE framework, the preliminary results of a pilot trial with secondary school students will be presented; these results will lead to the final remarks and directions for further developments.

Il presepe di Andrea Tipa nel Monastero de las Salesas Reales di Madrid
2022
The essay studies the nativity scene in coral, ivory and precious materials in the Monasterio de las Salesas Reales in Madrid, made by Andrea Tipa in 1749, the only work known to date to bear the signature of the master from Trapani. The Madrid nativity scene is contextualised with the production so far attributed to Andrea and the Tipa family and its exhibition history and restoration are reconstructed.
I PROFETI DELLA SECONDA REPUBBLICA
2015
The essay reconstructs a genealogy of social and political scientists who, since the birth of the Italian Republic, asked for an anti-party presidential transformation. From many quarters it was asked to move to a second Republic that seemed to be realized in the early nineties, with the birth of the League and Forza Italy and the collapse of the Republic of parties.
