Ecological risk assessment of agricultural soils for the definition of soil screening values: A comparison between substance-based and matrix-based a…
2017
The Italian legislation on contaminated soils does not include the Ecological Risk Assessment (ERA) and this deficiency has important consequences for the sustainable management of agricultural soils. The present research compares the results of two ERA procedures applied to agriculture (i) one based on the “substance-based” approach and (ii) a second based on the “matrix-based” approach. In the former the soil screening values (SVs) for individual substances were derived according to institutional foreign guidelines. In the latter, the SVs characterizing the whole-matrix were derived originally by the authors by means of experimental activity.\ud \ud \ud The results indicate that the “matr…
Could cattle ranching and soybean cultivation be sustainable? A systematic review and a meta-analysis for the Amazon
2021
Abstract: Tropical forests are being destroyed to make space for agricultural activities with the assumption that they are required to feed the growing global population. Consequently, more sustainable practices are needed to guarantee food security and environmental protection of highly threatened natural biodiversity hotspots like the Amazon rainforest. Cattle ranching and soybean cultivation are by far the greater drivers of land use change and deforestation in the Amazon region. We performed a systematic review of papers related to these two main drivers and a meta-analysis on the effects of sustainable practices on different ecosystem services. The results of the review highlight a lar…
Electronic Health Record in Italy and Personal Data Protection.
2016
The present article deals with the Italian Electronic Health Record (hereinafter ehr), recently introduced by Act 221/2012, with a specific focus on personal data protection. Privacy issues — e.g., informed consent, data processing, patients’ rights and minors’ will — are discussed within the framework of recent e-Health legislation, national Data Protection Code, the related Data Protection Authority pronouncements and eu law. The paper is aimed at discussing the problems arising from a complex, fragmentary and sometimes uncertain legal framework on e-Health.
Paesaggio, piano, progetto: problemi lessicali e altro
2012
The notion of landscape and the techniques for landscape design must necessarily be based on two principal regulatory provisions, the European Landscape Convention and in Italy the law on cultural heritage and landscape. Consideration must also be given to what is meant by the term ‘landscape' in normal and specialist parlance and to the nature of the training of landscape architects, because it is from all this that the ambiguities and misunderstandings that surround the notion of landscape originate. Consideration must also be given to the relations between planning and real and local transformations, because the contents and procedures for the formulation of designs depend on them. Lands…
Il riciclo produttivo dei beni confiscati. Il caso studio del “Pazo Baión”
2017
Il presente articolo affronta il tema del reinserimento dei beni confiscati alla criminalità organizzata in nuovi cicli di vita produttivi. La ricerca indaga il fenomeno con il proposito di rispondere ai seguenti quesiti: è possibile immaginare un modo diverso di riattivare i beni confiscati alla criminalità organizzata? Il riuso sociale dei beni confiscati è uno strumento utile o va aggiornato? Quali pratiche possono essere utili per la ridefinizione degli strumenti con i quali l’urbanistica concepisce, governa e replica processi di riciclo di prodotti spaziali che hanno terminato un ciclo di vita legato a propositi d’influenza sociale, profitto economico e controllo degli ambienti antropi…
Ri-ciclo urbano post-criminale. Il caso del Quartiere dei Marinai di Anversa
2017
Il presente articolo affronta il tema del rapporto fra urbanistica e trasformazioni urbane in contesti caratterizzati dalla presenza di organizzazioni criminali. La ricerca indaga la questione della ridefinizione dei modelli teorici, d’intervento e di valutazione con i quali l’urbanistica concepisce, governa e replica la riattivazione produttiva di parti urbane che hanno terminato un ciclo di vita legato a propositi d’influenza sociale, profitto economico e controllo degli ambienti antropizzati da parte delle organizzazioni criminali. L’articolo affronta i seguenti quesiti: quali sono i limiti e le criticità dell’azione pubblica in contesti affetti dal fenomeno della criminalità organizzata…
Exploiting community detection to recommend privacy policies in decentralized online social networks
2018
The usage of Online Social Networks (OSNs) has become a daily activity for billions of people that share their contents and personal information with the other users. Regardless of the platform exploited to provide the OSNs’ services, these contents’ sharing could expose the OSNs’ users to a number of privacy risks if proper privacy-preserving mechanisms are not provided. Indeed, users must be able to define its own privacy policies that are exploited by the OSN to regulate access to the shared contents. To reduce such users’ privacy risks, we propose a Privacy Policies Recommended System (PPRS) that assists the users in defining their own privacy policies. Besides suggesting the most appro…
Analysis of the efficacy of a WiFi architecture for the management of medium voltage distribution systems
2010
The paper illustrates the interventions for improving security of a WiFi communication system applied in the automatic management of a Medium Voltage network. The management system fails if the data measured at the secondary substations can’t flow regularly. In this paper the security of the transmission as function of the action range of the radio channel, on the data sending time of the IEEE 802.11 protocol, and of the out of use of a WiFi node. Then, a modified IEEE 802.11 protocol is described, for making secure the transmission in presence of a high number of WiFI nodes. Finally, a probabilistic analysis in presented for analyzing the problem from an economical point of view.
Decentralized Intrusion Detection In Cooperative Multi-Agent Systems
Toward a Society of Robots: Behavior, Misbehavior, and Security
2010
In this article, we consider how a very large numbers of robots, differing in their bodies, sensing, and intelligence, may be made to coexist, communicate, and compete fairly toward achieving their individual goals, i.e., to build a society of robots. We discuss some characteristics that the rules defining acceptable social behaviors should possess. We consider threats that may be posed to such a society by the misbehaviors of some of its members, either due to faults or malice, and the possibility to detect and isolate them through cooperation of peers. The article presents examples of motion control protocols, for arbitrarily large groups of heterogeneous robots. We discuss intrusion dete…
