Agenda urbana in Italia: slittamenti di scale territoriali e paradigmi progettuali

2014

L’interesse per le città che da qualche tempo permea le politiche di coesione regionale in Europa coincide in Italia, in un orizzonte cronologicamente più ristretto, con una rinnovata centralità della dimensione nazionale nell’orientamento e regolazione delle politiche locali. A quest’esito, invero parziale ma politicamente piuttosto delineato, concorrono almeno un paio di processi tra loro interdipendenti. Da un lato, il riconoscimento della fragilità delle regioni (in particolare di quelle meridionali) nel governo di politiche complesse e multilivello tra le quali vanno certamente annoverate quelle per lo sviluppo e la rigenerazione delle aree urbane. Dall’altro, un più complesso processo…

Root rot of pea: characterization and biocontrol of the soil-borne disease complex including Aphanomyces euteiches

2018

Pea root rot is an increasing constraint in most of intensive pea cropping areas across the globe. The pathogenic complex responsible for the disease is composed of soil-borne fungal and oomycete pathogens such as Fusarium solani, F.oxysporum, F. avenaceum, F. culmorum, Rhizoctonia solani, Thielaviopsis basicola, Ascochyta pinodella, Pythium spp., Aphanomyces euteiches and probably others not yet identified. The diversity of their ecological and pathogenic properties can explain the worldwide dispersion of the disease and the absence of chemical, agricultural or genetic control tools. My research program aims at characterizing the parasitic consortium occurring in the North of France and at…

Interest Rate Convergence, External Balances and the Euro Crisis

2016

Typically, the catching-up process between rich Northern Europe and poor Southern Europe and the diverging cost competitiveness between the two regions are considered alternative explanations for the widening current account imbalances in the euro area. This paper proposes a new explanation for the imbalances which led to the 2009 euro crisis i.e. large interest rate differentials among the EMU-12 countries which prevailed before the adoption of the euro. This finding suggests that the euro crisis was, at least to some extent, a consequence of the initial convergence shock.

Simplified restructuring proceedings in Poland as an example of anti – crisis regulation due to the COVID-19 pandemic

2020

Summary The study discusses new legislative anti – crisis solutions adopted in Poland in connection with the COVID – 19 pandemic. The Polish legislator decided to introduce the so-called simplified restructuring procedure. This happened in the face of the expectations of both the jurisprudence of law and practice. On the one hand, the simplified restructuring procedure (the fifth independent type of restructuring procedure for an entrepreneur in Poland) allows for a quick, cheap and simplified conclusion of an arrangement with creditors outside the court, then approved by the court. On the other hand, the opening of such proceedings gives the debtor protection against enforcement at the cre…

On Ibn Ezra's Procedure and Shapley Value

2014

We examine ibn Ezra's procedure (Rabinovitch 1973; O'Neill 1982) historically used to solve the Rights Arbitration problem in the general framework of bankruptcy problems. When the greatest claim is larger than or equal to the estate, the procedure is a maximal game (Aumann 2010). However, when the greatest claim is smaller than the estate, the axioms of efficiency (the whole estate is distributed) and satiation are difficult to satisfy simultaneously. We discuss both axioms to show that their importance and necessity are radically different. From then, for the part of the estate not covered by the greatest claim, we examine four possible procedures: the minimal overlap rule, Alcalde et al.…

Improving the solid-phase extraction of “quat” pesticides from water samples

1998

A novel strategy, based on the addition of a cationic surfactant, for preventing the interferences associated with a diminution in the efficacy of solid-phase extraction (SPE) with silica cartridges of diquat, paraquat and difenzoquat in water is developed. Conditions for extraction are optimised with respect to pH, cationic surfactant and its concentration. Humic acids, anionic surfactants, inorganic salts and other organic contaminants like pesticides, phenols, polycyclic aromatic hydrocarbons and polychlorinated biphenyls produce the studied interferences. The best performance is shown in the improvement of the "quats" recovery from waters with high levels of humic acids and anionic surf…

Budget burden and benefit visibility of European central level governments

2001

Central levels of government in European Union member countries are different regarding their basic institutions, powers, fiscal systems, accountability, public performance management, financial control bodies, and the like. In spite of this, the economic operation of such levels of government should be analyzed, evaluated, and compared from an efficiency viewpoint. This paper presents general indicators to systematically assess the burden and benefit visibility of public budgets of the International Monetary Fund member countries and specific estimates for the central subsystems of public revenue and expenditure now in force in such European countries. An important policy implication of th…

Effect of Acoustic Wave Reflections on Space Charge Measurements with PEA Method

2018

The Pulsed Electro-Acoustic (PEA) method is the most used technique for space charge detection in solid dielectrics. The methodology is largely employed in the field of High Voltage Direct Current (HVDC) transmission and is based on the detection of acoustic waves generated by charges vibration. One of the most common problems arising during the detection is the presence of multiple reflections taking place due to the presence of means discontinuity in the different PEA cell components. This reflection phenomenon, if not well taken into account, could cause incorrect interpretation of the PEA output signal. It is easy to understand that a simulation model is a basic tool to understand the w…
