How Geography and Climate Shaped the Genomic Diversity of Italian Local Cattle and Sheep Breeds
2022
International audience; Understanding the relationships among geography, climate, and genetics is increasingly important for animal farming and breeding. In this study, we examine these inter-relationships in the context of local cattle and sheep breeds distributed along the Italian territory. To this aim, we used redundancy analysis on genomic data from previous projects combined with geographical coordinates and corresponding climatic data. The effect of geographic factors (latitude and longitude) was more important in sheep (26.4%) than that in cattle (13.8%). Once geography had been partialled out of analysis, 10.1% of cattle genomic diversity and 13.3% of that of sheep could be ascribe…

Genomic Tools for the Characterization of Local Animal Genetic Resources: Application in Mascaruna Goat
2022
Italy contains a large number of local goat populations, some of which do not have a recognized genetic structure. The “Mascaruna” is a goat population reared for milk production in Sicily. In this study, a total of 72 individuals were genotyped with the Illumina Goat_IGGC_65K_v2 BeadChip with the aim to characterize the genetic diversity, population structure and relatedness with another 31 Italian goat populations. The results displayed a moderate level of genetic variability for Mascaruna, in concordance with the estimated values for Italian goats. Runs of homozygosity islands are linked to genes involved in milk production, immune response and local adaptation. Population structure anal…
The sirocco chambers: passive cooling structures in the XVI century Palermo area
2014
In the past centuries, the plain surrounding the city of Palermo saw the construction of tens of suburban manor houses, called villas, which were referred to as “places of delight” for the amenities they offered during the good season. These architectural machines were built by aristocrats to make living in the countryside more pleasant and to exhibit their families’ richness and power. Among the delights, the Sirocco rooms were very common in Palermo from the Renaissance, and especially beyond to the XVIII century. They were artificial subterranean structures, built close to a water spring in order to reproduce the pleasant conditions of freshness that could be experienced in a natural cav…
The preservation of the Agrigento Cathedral
2013
The Agrigento Cathedral was built about nine centuries ago on the edge of a steep slope made up of alternating inclined layers of soft calcarenites and fine-grained soils; its behaviour has never been satisfactory especially as far as the North aisle is concerned. Many corrective measures have been attempted during its lifespan and also a few years ago. They proved invariably unsuccessful. Recent geotechnical investigations, referred to in the paper, permitted to find out that the main cause of the Cathedral distress is a sliding mechanism involving the upper zone of the slope underlying the North aisle; consequently the essential requirement for the preservation of the Cathedral is the sta…
Right to the Future
2017
During the last decade, the city of Palermo has been undergoing relevant transformations from various perspectives. This has been the consequences of a multitude of circumstances, European financial crisis, migrants/refugees crisis, a new administration of the city and an increased awareness and responsibility among the citizens. Various national and international recognitions (Italian Cultural Capital 2018, the European Biennial of Contemporary Art, Manifesta 12, Youth Capital 2017) have confirmed that they are on the right path. This positive moment has been launched and, progressively, rid- den by many young professionals that decided to challenge the present situation by investing their…
Material and immaterial culture of the internal minor centres. Studies and researches for the ecological transition of the Madonie inner mountain are…
2022
Presently, the European Union strategies aim at strengthening the rural areas that are characterized by a deep depopulation, people aging, and a weak employment market. In these "marginalized" areas, the urban regeneration process may be assisted by the creation of smart villages, realities that will cooperate and create innovative small towns. The Sicilian inner mountain area, in particular, consists of twenty-one villages - mostly dating back to the Middle Age - that present an attractive localization due to naturalistic, landscape and cultural features, also qualified by a well-preserved geographical area whose main building typological features were not altered during time. This paper p…
Non profit per chi? Riflessioni sul ruolo del Terzo Settore nella costruzione di una nuova politica per la casa a Palermo
2018
Recent social housing programme reforms in Southern European Countries emphasise homeless involvement in the public discussion about planning and the delivery of housing. Experiences in a new social housing Italian programme and recent studies on the subject (Viglianisi, 2014; Laino and Vitale, 2015; Lo Piccolo and Giampino, 2016) reveal a number of obstacles for what concerns homeless participation in social housing programmes. This article critically assesses Arnstein’s ladder in relation to the institutionalization of homeless participation in the new social housing Italian programme "Multi-fund National Operational Programme Metropolitan Cities 2014-2020", on evidence from the case stud…
I soffitti in legno e canne. conoscenza e tecniche di intervento per una manutenzione sostenibili
2014
This study aims to analyze the vaulted and having a flat surface wooden ceilings that in Italy as well as in the all Europe found a great diffusion from XVII century to the first half of XX century, qualifying in the more complex and representative examples the monumental buildings, and often supporting at the intrados an unique and irreplaceable decoration. We believe that the knowledge of materials and construction techniques used for the original creation of these wooden carpentries, which draw on the "rules of art", is fundamental to support technicians and the other restorers in choosing the most appropriate intervention, addressing to the use of "sustainable choices" that could promot…
