No full textMafia-type Organisations and Extortion in Italy
No full textMafia-type organizations generate several distorting effects on the economy. In Italy their presence is endemic, and not only in Southern regions such as Sicily, Campania or Calabria. Such organizations endure the fierce and continuous pressure exerted by Italian anti-mafia policy, maybe the most articulate and effective such policy in the world. Nevertheless, they have survived by submerging, transforming, and relocating their operations.
The analysis of the different Mafias of today benefits from a huge amount of empirical data produced by investigators. This allows us to outline more reliable indexes of the penetration of Mafiosi in given territories, as well as to estimate the size of their activities in a transparent and empirically testable way. The contributions gathered in this book stem from the application of an innovative methodology originally introduced by the Fondazione Rocco Chinnici, and they enlarge our understanding of such a complex and dynamic phenomenon. After the presentation of the approach, the chapters are devoted to the Camorra's present situation, to an estimate of the size of extortion, to a comparison between Cosa Nostra and Camorra, to the analysis of wiretapped conversations and, finally, to the delocalization of Mafias and the perspectives of a European anti-mafia policy. This book was originally published as a special issue of Global Crime
Coagulation/chlorination of surface water: A comparison between chitosan and metal salts.
No full textCoagulation and subsequent chlorination are typically used for surface water treatment in order to produce potable water. Chitosan, a linear cationic polymer of high molecular weight, has recently been proposed for application in drinking water treatment as potential alternative to metal species based coagulants. However, due to its nature some organic matter may be released during coagulation step, thus increasing the concentration of disinfection by-products as well as the toxicity of finished water. In the present paper the efficiency of chitosan and conventional coagulants
(aluminium sulphate and ferric chloride) was compared in terms of turbidity and natural organic matter (NOM) removal, as well as acute toxicity on Daphnia magna of coagulated and coagulated/chlorinated surface water. The coagulation experiments were carried out by jar test using low TOC and high alkalinity surface water. Turbidity and NOM removal, as well as toxicity were investigated (i) under actual conditions, (ii) for different pH (5, 6, 7) and (iii) in humic acid (HA) spiked surface water samples. All coagulants decreased toxicity on D. magna from 100% to 0%
immobilization. However, the addition of humic acids affected final toxicity in different ways according to coagulant type and dose. Moreover, the chlorination step after coagulation increased toxicity too according to the coagulant type as follows: chitosan > ferric chloride > aluminium sulphate
