Single intense prenatal stress reduce behavioural suppression in an operant conflict paradigm in the adult progeny. Influence of Metyrapone administr…
2008
Stressors presented during late prenatal period can have long-term effects on offspring behaviour (1). Indeed we showed that in the rat progeny a single immobilization procedure at gestational day 16 enhances spatial learning in a non-aversive, rewarded-facilitated learning task, the Can Test, and decreases anxiety-like behaviour in the elevated plus maze (2). In this study, we wanted to investigate: (i) the effects of a single prenatal immobilization-stress on the operant conflict task (OCT), an anxiety-related procedure, in which positively reinforced responses are suppressed by contingent punishment (3); (ii) the expression of mineralcorticoid and glucocorticoid receptors (MRs, GRs) in t…
Development of an early warning system to predict sewer overflow
Flash flooding in our city is still a fairly common phenomenon.Unfortunately, the development of a flash flood forecasting system in urban areas is not a simple and unambiguous procedure.While attending the PhD course in Civil and Environmental Engineering, research activity has been given to realize an urban overflowing prediction system that was best as possible suited to the drainage network of the city of Palermo. With the support of radar data and hybrid hydraulic model for drainage network has been possible to demonstrate the effectiveness of this instrument, while the reduction of residual flood risk has been supported by modern resilience measures.
Oltre i confini: verso la regionalizzazione dell'urbano. W 1.2 Il paradigma bio-regionale per il progetto di ri-territorializzazione (re-embedding) d…
2019
Il capitolo rende conto di una rilettura ed interpretazione del paradigma bio-regionale come riferimento per pratiche interpretative, di governance e progetto di territorio finalizzate alla “ril-ocalizzazione” dell’insediamento umano nel suo milieu socio-culturale ed ambientale di prossimità. Il riferimento primario è all’ampio e polifonico movimento culturale bio-regionale sviluppatosi in particolare negli Stati Uniti tra la fine degli anni sessanta e l’inizio degli anni settanta del XX secolo.
A Quantum-Inspired Classifier for Early Web Bot Detection
2022
This paper introduces a novel approach, inspired by the principles of Quantum Computing, to address web bot detection in terms of real-time classification of an incoming data stream of HTTP request headers, in order to ensure the shortest decision time with the highest accuracy. The proposed approach exploits the analogy between the intrinsic correlation of two or more particles and the dependence of each HTTP request on the preceding ones. Starting from the a-posteriori probability of each request to belong to a particular class, it is possible to assign a Qubit state representing a combination of the aforementioned probabilities for all available observations of the time series. By levera…
A genetic algorithm for the design of a fuzzy controller for active queue management
2003
Active queue management (AQM) policies are those\ud policies of router queue management that allow for the detection of network congestion, the notification of such occurrences to the\ud hosts on the network borders, and the adoption of a suitable control\ud policy. This paper proposes the adoption of a fuzzy proportional\ud integral (FPI) controller as an active queue manager for Internet\ud routers. The analytical design of the proposed FPI controller is\ud carried out in analogy with a proportional integral (PI) controller,\ud which recently has been proposed for AQM. A genetic algorithm is\ud proposed for tuning of the FPI controller parameters with respect\ud to optimal disturbance rej…
The Exclusion of Women from Inheritance Rights: An Unresolved Issue?
2021
In Italy, the women's exclusion from the inheritance is the principle that structures the property system of the families in medieval and early modern age and the social and juridical organization of these centuries, until the XIX century. Despite its importance, the exclusion of the women has never been an autonomous historiographical issue, but it has been ignored to advantage of analysis centered on the dowry system: emphasis has been placed mainly on the property rights of the women instead of observing the marginalization of the female part of lineages respect to the family wealths. The essay addresses two issues: the way in which statutory and state laws rule women’s exclusion from in…
Tendenze e indirizzi della storia di genere sull’età moderna in Italia. Un itinerario attorno alla Società Italiana delle Storiche
2019
Il saggio esamina le tendenze della storiografia italiana in ordine alle tematiche di genere, concentrandosi sull'età moderna. A tal fine, si assumono le iniziative scientifiche della Società italiana delle storiche, le ricerche e le pubblicazioni promosse nel corso dei suoi trent'anni di attività come terreno di indagine privilegiato per la rilevanza che l'organizzazione ha avuto e ha nel campo degli studi di storia delle donne e di genere.
Se il diritto costruisce la storia delle donne. Una relazione nel campo della modernistica italiana
2019
Il contributo si colloca in una discussione collettiva sulle vicende della storia delle donne e di genere a venticinque anni dalla pubblicazione della Storia delle donne a cura di Duby e Perrot ed esamina in particolare gli studi compiuti dalla storiografia italiana sull'età moderna intorno alla condizione giuridica delle donne e alla loro capacità di promuoversi (agency) considerando tanto la prospettiva delle storiche quanto quella di studiose e studiosi della storia giuridica, per valorizzare il ruolo del diritto nella comprensione dei fenomeni storico-sociali.
Early pastoral communities in the mountains of Sicily. Prehistoric evidence from Vallone Inferno (Scillato) in the palaeoenvironmental framework of t…
2021
Abstract This paper discusses the Middle Neolithic and the Early Bronze Age phases of the occupation of a rock shelter at Vallone Inferno (Scillato, Palermo) in Sicily. Vallone Inferno is a key site for studying the early establishment and development of pastoralism in the prehistoric mountainous environments of Sicily. Seasonal use of the site as a shelter is documented for the earliest pastoral communities that exploited the Madonie mountain range. The results of the analysis of pottery and lithic assemblages contribute to the definition of two chronocultural frameworks that were linked by the same economic subsistence base. The special role of obsidian emerges, while the mobility pattern…
Tolemeo di Mauretania. L’ideologia politica e la morte a Roma nel settembre del 40
2022
The paper, through the analysis of literary, numismatic and epigraphic sources, and through the contribution of statuary, aims at investigating the causes that determined first the fall into disgrace, and then the death sentence of Ptolemy of Mauretania. A set of reasons, the main of which have an ideological-political and cultural nature, and can be summarized in a self-congratulatory intention, is behind the death sentence of the king, that we propose to contextualize in Rome, after a period of imprisonment, not before September 40 BC, when Caligula went back from Campania.
