Impact of plant cover on the cavity-nesting antTemnothorax crassispinus
2017
1. Plant communities influence the availability of important resources for ants, such as nest sites and food, as well as environmental conditions. Thus, plants affect the abundance and distribution of ants. 2. In a field experiment, the influence of plant cover on the settlement of nest sites and per-capita productivity of sexual individuals by the ant Temnothorax crassispinus was analysed. In July 2014, in five areas with patches of alien balsam Impatiens parviflora, and another five of native balsam I. noli-tangere, transects composed of artificial nests were established; the nest sites were situated inside patches of balsams, and outside of them. Four hundred and forty artificial nests w…

SUCCESSO E DECLINO DELLA SCUOLA GENOVESIANA IN SICILIA SUL FINIRE DEL XVIII E IL PRINCIPIO DEL XIX SECOLO
2021
In the Sicily of late 18th century, during the harshest contraposition between viceroyal government and parliamentary baronage, the Genovesian school gains a great success on the island among scholars and academicians as well as ruling class. In this particular moment of Sicilian history, the theme of reforms is at the top of the political agenda and the thought of Genovesi and his scholars spurs projects to reform the old institutions of the Kingdom, to modernize agriculture, raise productivity and introduce a fairer taxation. The reputation of the Neapolitan school is so well-known that all the parties are inspired by Its economic and political proposals. Furthermore, the Crown and the ba…
Identification of diterpenes in canvas painting varnishes by gas chromatography-mass spectrometry with combined derivatisation.
2004
A derivatisation method that combines the formation of ethyl esters from the carboxylic groups and trimethylsilyl ethers from hydroxyl groups of the components of diterpenic resins is presented in this paper. This methodology involves two experimental steps: (1) formation of ethyl esters using ethyl chloroformate; and (2) the esterified compounds are lead to react with trimethylsilylimidazole to form the corresponding trimethylsilyl ethers. The main advantage of the proposed method is the possibility of performing simultaneously the analysis of amino acids from proteins, fatty acids from drying oils, and diterpenic compounds from natural resins usually found in works of art. This methodolog…
European Politics of Food Origin. A Semiotic Analysis of Geographical Indications
2021
This chapter investigates the relationship between food products and origin places within the European Union food policies. In the 1990s, the EU established a Geographical Indication (GI) system, constituted of a set of food quality brands and a legal framework for food, wine and spirits. This system, defined as a sui generis model by insiders, entails a strong EU government participation in the typical food symbolic and material modelling. The sui generis model establishes a government monopoly on the place-based labels registration and institutes an atypical kind of intellectual property based on geographic marks. By proposing a semiotic approach toward the analysis of European Geographic…

The Myth of Io and Female Cyborgic Identity
2020
The figure of Io, the priestess of Hera seducted by Zeus and turned into a cow that wanders from Argo to Egypt pursued by a gadfly, shares in Hera’s bovine imagery and can be considered as a mythical paradigm of the unavoidable ‘yoke’ of love and marriage for women. She actually takes back a fully human aspect by means of conceiving and bearing Epaphus, a son with a name that tells his exceptional conception and divine birth. In the light of readings of some core studies concerning the theory of the cyborg, this paper aims at showing that the girl-heifer – sometimes also represented as a girl-bull, a possible link with Dionysus as hypostasis of sexual potency and fertility – does not only u…
New insights into the composition of historical remedies and pharmaceutical formulations: the identification of natural resins and balsams by gas chr…
2020
AbstractThe present paper reports one of the first studies on the identification of natural resins and balsams in modern era drug formulations. Gas chromatography coupled with mass spectrometry (GC-MS) was applied to investigate the composition of ancient remedies and pharmaceutical formulations coming from the Spezieria di Santa Maria della Scala in Rome, founded at the end of the seventeenth century by the Discalced Carmelites. The obtained results highlight the presence of complex mixtures containing resinaceous and lipidic-based compounds. Thanks to the detection of characteristic markers, it was possible to identify several natural resins, such as guaiacum resin, ladano resin and scamm…
L'Economista Anglofilo. Paolo Balsamo e l'utopia liberale in Sicilia (1787-1816)
2023
Paolo Balsamo -economist and professor of University of Palermo from 1787 to 1812- was a traveller and expert in the most advanced and modern British and European agriculture. He wrote articles and essays, both in English and Italian, on agriculture and political economy and was a correspondent of important cultural and political circles of British Whiggism. As a member of the Sicilian Parliament, ideologist of the constitutional party and trusted collaborator of Lord Bentinck, he wrote the Sicilian Constitution of 1812 which reformed the old institution of the Kingdom of Sicily transforming it into a liberal State. This monography explores Balsamo's intellectual and political figure throug…
Paolo Balsamo, Smithianism and the Birth of Liberalism in Sicily
2020
The article focuses on the transition process of Sicily, between the end of 18th century and the beginning of 19th, from the Ancien Regime to a modern society, underlining the intellectual and political role of the Sicilian economist Paolo Balsamo. The professor of Agriculture and Economics at University of Palermo founded the Sicilian liberalism on Adam Smith’s works and tried to reform the institutions of the island aiming to make them the model of a Smithian nation. The article analyses Balsamo’s work by highlighting the interlacement of culture, social interests and political emergencies, all of which had an effect on how Smithianism was adopted in Sicily.
