Retorica e costruzione del consenso in Tucidide: il caso di Mitilene.
2016
In his account of the Peloponnesian war, Thucydides explicitly insists on some dilemmas linked to the wider matter of deliberative process: in particular, the relationship between nature, profit and justice, truth and lie, speech and action. The story of the uprising of Mytilene is particularly useful, intertwining the antilogy between the two speakers (Cleon and Diodotus) with the so-called metanoia: the Athenian deliberative rethinking puts on focus the complex problems of the building of consensus in the democratic decision-making processes. Here we examine only one point of the two rich and articulate speeches: the opportunity of discussing again what has been already decided in a corre…
Designing empirical experiments to compare interactive multiobjective optimization methods
2022
Interactive multiobjective optimization methods operate iteratively so that a decision maker directs the solution process by providing preference information, and only solutions of interest are generated. These methods limit the amount of information considered in each iteration and support the decision maker in learning about the trade-offs. Many interactive methods have been developed, and they differ in technical aspects and the type of preference information used. Finding the most appropriate method for a problem to be solved is challenging, and supporting the selection is crucial. Published research lacks information on the conducted experiments’ specifics (e.g. questions asked), makin…
Exploring the Underground Economy through System Dynamics to support Public Decision Makers: a preliminary qualitative analysis
2008
To estimate and analyse the underground economy phenomenon, different methods and approaches have been provided in literature. However, such approaches are very often based on static and linear equilibrium models and seldom adopt simulation tools. This paper results from a research project conducted in the Sicily Region (Italy) aimed at investigating – through the System Dynamics methodology – main causes-and-effects relationships underlying the phenomenon of the “hidden workers” at both firm and self-employment level. By combining micro and macro-analysis, the authors present a preliminary causal loop diagram of the investigated phenomenon. Such feedback structure has been built through th…
Interactive data-driven multiobjective optimization of metallurgical properties of microalloyed steels using the DESDEO framework
2023
Solving real-life data-driven multiobjective optimization problems involves many complicated challenges. These challenges include preprocessing the data, modelling the objective functions, getting a meaningful formulation of the problem, and supporting decision makers to find preferred solutions in the existence of conflicting objective functions. In this paper, we tackle the problem of optimizing the composition of microalloyed steels to get good mechanical properties such as yield strength, percentage elongation, and Charpy energy. We formulate a problem with six objective functions based on data available and support two decision makers in finding a solution that satisfies them both. To …
Development of a Roadmap for the Implementation of a Sustainable Mobility Action Plan in University Campuses of Emerging Countries
2022
Universities are centers of knowledge and their Campuses are like small cities, thus making them the ideal place to develop, apply and evaluate policies and tools for innovative mobility solutions that can subsequently be extended to other contexts. A review of mobility measures in different European Universities has revealed that many of them apply policies to promote sustainable mobility, but there is a significant lack of standardized mobility plans and roadmaps for their successful implementation. The objective of the present work is to develop a successful roadmap, which is necessary for the smooth implementation of a mobility plan, as it has been found through a thorough review of goo…
