Dendrolatrie. Miti e pratiche dell'immaginario arboreo
2021
L’avvento dell’Antropoce, epoca in cui l’essere umano è diventato una forza geologica, scompagina la divisione del sapere tra scienze umane e naturali. Per comprenderlo, è necessario costruire nuove forme di alleanza tra discipline. È quanto invita a fare anche il fe- nomeno delle dendrolatrie. Diffuso in ogni luogo e in ogni epoca, il culto degli alberi testimonia come il mondo arboreo abbia plasma- to modi di vivere e di pensare, venendone a sua volta trasformato. Per scavare nella complessità di questo scambio, il volume racco- glie i frutti del dialogo tra un gruppo interdisciplinare di ricercatrici e ricercatori che esplorano l’immaginario arboreo in tre direzioni: quella degli studi s…
La photographie engageante di JR: integrazione e intersezione tra immagini e città
JR's street art actions reflect on the life and history of cities and the ways of living there. The giant images of the faces of the inhabitants proposed in their own places of life invite to project the memory into the present using the power of photography to interpret faces: no longer masks but living representations, witnesses of the symbiotic relationship between inhabitants and cities.
Art in the streets. Artification strategies for public space
2019
My essay focuses on the notion of artification, recently emerged in the philosophical and artistic debate. Some case studies show that “public wall paintings” work as an artifying strategy of public space both at a superficial and at a deep level. As regard to the first, a mere decorative effect is produced; while the second, by launching projects which require the coordination of several professional skills and social actors, produces a more radical transformation. The latter notion of artification is more significant than the former because it better expresses the educational value of art and its ability to produce improvement not only of urban areas – made aesthetically more enjoyable – …
Artificare lo spazio urbano. Lo sguardo “altro” di Danisinni
2019
Se nella città di Palermo, come in altre città italiane e del mondo, l’incompiuto è segno di un percorso trasformativo che ha subito un arresto, nel rione palermitano di Danisinni l’incompiuto è simbolo di una dimensione esistenziale. Infatti, non solo dal punto di vista topografico, ma anche da quello economico e sociale Danisinni costituisce un mondo chiuso in sé stesso: è un villaggio dentro la città, ma al contempo è un luogo periferico e marginale, tagliato anche dai collegamenti pubblici. Tuttavia negli ultimi anni in questo quartiere sono stati avviati dei processi di riqualificazione urbana che hanno fatto ricorso alle arti da strada (murales, spettacoli teatrali e circensi). Il sag…
Analysis of early strains of the norovirus pandemic variant GII.4 Sydney 2012 identifies mutations in adaptive sites of the capsid protein.
2014
AbstractGlobal surveillance for norovirus identified in 2012 the emergence of a novel pandemic GII.4 variant, termed Sydney 2012. In Italy, the novel pandemic variant was identified as early as November 2011 but became predominant only in the winter season 2012–2013. Upon sequencing and comparison with strains of global origin, the early Sydney 2012 strains were found to differ from those spreading in 2012–2013 in the capsid (ORF2) putative epitopes B, C and D, segregating into a distinct phylogenetic clade. At least three residues (333, 340 and 393, in epitopes B, C and D, respectively) of the VP1 varied among Sydney 2012 strains of different clades. These findings suggest that the spread …
Epidemiological dynamics of norovirus GII.4 variant New Orleans 2009.
2015
Norovirus (NoV) is one of the major causes of diarrhoeal disease with epidemic, outbreak and sporadic patterns in humans of all ages worldwide. NoVs of genotype GII.4 cause nearly 80–90 % of all NoV infections in humans. Periodically, some GII.4 strains become predominant, generating major pandemic variants. Retrospective analysis of the GII.4 NoV strains detected in Italy between 2007 and 2013 indicated that the pandemic variant New Orleans 2009 emerged in Italy in the late 2009, became predominant in 2010–2011 and continued to circulate in a sporadic fashion until April 2013. Upon phylogenetic analysis based on the small diagnostic regions A and C, the late New Orleans 2009 NoVs circulati…
Microbiological quality of Pecorino Siciliano "primosale" cheese on retail sale in the street markets of Palermo, Italy
2011
Pecorino Siciliano (PS) “primosale” is a traditional Sicilian fresh soft cheese made from sheep’s milk. Short-ripening time and production from unpasteurized or raw milk can facilitate bacterial contamination of PS “primosale”. The microbiological quality of “primosale” on retail sale in the street markets of Palermo, Italy was studied by detecting the common food pathogens Listeria monocytogenes and Staphylococcus aureus and indicator microorganisms, such as Escherichia coli, Enterobacteriaceae and Staphylococcaceae. In our study, 4% and 44% of the samples, respectively, did not comply with the acceptability levels fixed by European regulations for S. aureus and E. coli. A high contaminati…
[Deciding in conditions of uncertainty: the Delphi method and its use in the formulation of guidelines].
2001
The purpose of this paper is to analyze one of the most powerful tools in the decision-making under conditions of uncertainty, the Delphi method, and to verify the related interest of scientific world, particularly, for formulation of guidelines. The method combines the expert opinion preventing biases due to institutional role, status or dominant personality. In the text we explain the methodology and the steps through which it is possible to realize the consensus; we schematized in a didactic manner all the phases for an operational approach of the reader. The search by the most diffused biomedical database (Medline) individualized 623 citations, 7 of which are guidelines (3 of remarkable…
Much more than a clasp: Evolutionary pattern of amplexus diversity in anurans
2019
ABSTRACTThe evolution and diversification of animal reproductive modes have been pivotal questions in behavioral ecology. Amphibians present the highest diversity of reproductive modes among vertebrates, involving various behavioral, physiological and morphological traits. One of such features is the amplexus, the clasp or embrace of males on females during reproduction, which is almost universal to anurans. Hypotheses about the origin amplexus are limited and have not been thoroughly tested, nor had they taken into account evolutionary relationships in most comparative studies. However, these considerations are crucial to understand the evolution of reproductive modes. Here, using an evolu…
Evolutionary processes in the emergence and recent spread of the syphilis agent, Treponema pallidum
2022
Abstract The incidence of syphilis has risen worldwide in the last decade in spite of being an easily treated infection. The causative agent of this sexually transmitted disease is the bacterium Treponema pallidum subspecies pallidum (TPA), very closely related to subsp. pertenue (TPE) and endemicum (TEN), responsible for the human treponematoses yaws and bejel, respectively. Although much focus has been placed on the question of the spatial and temporary origins of TPA, the processes driving the evolution and epidemiological spread of TPA since its divergence from TPE and TEN are not well understood. Here, we investigate the effects of recombination and selection as forces of genetic diver…
