<em>Airports and airlines: elements for a new regulatory framework in Italy</em> - The paper analyses the evolution of the regulatory framework of the airport systems in Italy. The first part of the paper addresses the question why it is so difficult to regulate the Italian airports by commenting on the...

This article describes the evaluation of indicators computed with a numerical simulation model of soil water and solute flow against field measurements of the amount of adsorbed and dissolved salts. In the Mediterranean environment,characterised by hot, dry summers, a field experiment on...

We introduce a simple extension of the minority game in which the market rewards contrarian (resp. trend-following) strategies when it is far from (resp. close to) efficiency. The model displays a smooth crossover from a regime where contrarians dominate to one where trend-followers dominate. In...

Price dynamics is analyzed in terms of a model which includes the possibility of effective forces due to trend followers or trend adverse strategies. The method is tested on the data of a minority-majority model and indeed it is capable of reconstructing the prevailing traders' strategies in a...

The Minority Game framework was recently generalized to account for the possibility that agents adapt not only through strategy selection but also by diversifying their response according to the kind of dynamical regime, or the risk, they perceive. Here we study the effects of this mechanism in...

An irrigation experiment using saline-sodic waters was carried out in 2004 in the Volturno river plain (southern Italy) to investigate the growth of the melon cultivar Tendral under saline-sodic conditions. Four salinity irrigation treatments (C, T0.5, T1 and T2) were tested using water with...

Melon plants (Cucumis melo L.) cv. Tendral were grown in an open field trial in 2004 to investigate the effect of increased saline sodic water concentration on yield, crop tolerance, fruit quality and ion content. Three saline water concentrations were created by adding 5, 10 and 20 g l-1...
