Italian Bloggers' Stories: Their Personalities and Interpersonal Relationship Quality
2009
Abstract: Personal blogs represent a new emergent phenomenon that draws attention of psycholo-gists. In this framework, the present paper discusses the opportunity of evaluating both bloggers’ per-sonalities and their social relationships quality using blog as a new research methodology. Blog usagedata, Big Five personality traits, Interpersonal relationships quality and Internet addiction were evalu-ated in a population of 30 Italian bloggers. Results about Big Five personality traits showed no specificpersonality patterns leading people to become bloggers. However, Italian bloggers describe them-selves as individuals considerably open to experience, very affiliative or friendly and capabl…
Robust optimality of linear saturated control in uncertain linear network flows
2008
We propose a novel approach that, given a linear saturated feedback control policy, asks for the objective function that makes robust optimal such a policy. The approach is specialized to a linear network flow system with unknown but bounded demand and politopic bounds on controlled flows. All results are derived via the Hamilton-Jacobi-Isaacs and viscosity theory.
ROBUST CONTROL STRATEGIES FOR MULTI—INVENTORY SYSTEMS WITH AVERAGE FLOW CONSTRAINTS
2006
Abstract In this paper we consider multi—inventory systems in presence of uncertain demand. We assume that i) demand is unknown but bounded in an assigned compact set and ii) the control inputs (controlled flows) are subject to assigned constraints. Given a long—term average demand, we select a nominal flow that feeds such a demand. In this context, we are interested in a control strategy that meets at each time all possible current demands and achieves the nominal flow in the average. We provide necessary and sufficient conditions for such a strategy to exist and we characterize the set of achievable flows. Such conditions are based on linear programming and thus they are constructive. In …
Robust control in uncertain multi-inventory systems and consensus problems
2008
Abstract We consider a continuous time linear multi–inventory system with unknown demands bounded within ellipsoids and controls bounded within polytopes. We address the problem of ∈-stabilizing the inventory since this implies some reduction of the inventory costs. The main results are certain conditions under which ∈-stabilizability is possible through a saturated linear state feedback control. The idea of this approach is similar to the consensus problem solution for a network of continuous time dynamic agents, where each agent evolves according to a first order dynamics has bounded control and it is subject to unknown but bounded disturbances. In this context, we derive conditions under…
La struttura diocesana nella Sicilia tardoantica e bizantina: i dati archeologici
2022
The reconstruction of ecclesiastical geography of Christian origins constitutes one of the most current fields of study of Postclassical Archeology in Europe. The contribution aims to update current knowledge on the state of research in Sicily in the light of the new data acquired from archeology.
La formazione iniziale dei docenti di sostegno attraverso la metodologia dello storytelling. Un'indagine nei laboratori del corso di specializzazione…
2018
The present work describes the results of a research conducted with 450 students and 52 laboratory teachers attending the degree course in Specialization support activities of the University of Palermo during the academic year 2017-2018. The validity of the Mcdrury’s & Alterio (2003) Storytelling model was checked thanks to the research process and in order to reinforce students’ reflective skills, narrative competence and critical revision.
Risorgere con Leopardi

SISTEMI VERDI COME CULTURA RIGENERATIVA: STRUMENTI E TECNOLOGIE
2021
The study analyzes and proposes in the historical and in the area immediately to it adjacent, the "values-nature" of the buildings through the creation of gardens wall and vertical gardens in the elevatiloy of non-monumental buildings. The study deepens in particular the specificity of the garden roof and the garden vertical, recognizing benefits and critical issues that distinguish these green systems for construction. It also deepens the concept of resilience in close relationship sustainability and regenerative design applied to the built environment. The theme of regenerative design is studied and promoted as an adaptive strategy at the design stage; it requires you to leave nature stre…
