Il sequestro informatico nel prisma del principio di proporzione
No full textThe author focuses on the seizure of IT material and on the latest jurisprudential guidelines on the necessary compliance with the principle of proportionality in case of seizure of the entire content of an IT system. Highlighted the difficulty of a convincing reductio ad unum of the investigative instrument in question with respect to the "traditional" seizure, also due to the higher rank of the individual rights affected by the measure, the Author underlines the inadequacy of the current legislation to balance the opposing interests at stake
‘Disconnecting from my smartphone is a privilege I do not have’: Mobile connection and disconnection practices among migrants and asylum seekers in three migrant reception centres of Sicily
No full textQuesto articolo indaga le pratiche di connessione e disconnessione online tra i migranti e i richiedenti asilo. Si basa su un'etnografia di tre centri di accoglienza siciliani che hanno ospitato migranti e richiedenti asilo tra settembre e novembre 2020. Mostriamo come i migranti, spinti da diverse motivazioni migratorie, mettano in atto diverse pratiche di connessione e disconnessione mobile. Sosteniamo che queste sono caratterizzate dai diversi significati affettivi che i migranti e i richiedenti asilo attribuiscono alla connessione e alla disconnessione mobile e dal diverso valore che attribuiscono alla dimensione pubblica e privata della loro vita. Offrendo un ritratto sfaccettato delle pratiche di connessione e disconnessione mobile di diverse categorie di migranti, questo articolo contribuisce anche: (1) agli studi sui media e sulle migrazioni, mostrando che esistono differenze sostanziali nelle pratiche di connessione online e nell'uso degli smartphone tra richiedenti asilo e migranti e (2) agli studi sulla disconnessione, evidenziando le sfumature che esistono nelle pratiche di disconnessione tra i gruppi sociali non privilegiati, come i migranti e i richiedenti asilo. Mostriamo che non possono permettersi di praticare forme di disconnessione tipicamente occidentali, urbane ed elitarie; tuttavia, anch'essi sono in grado di praticare forme specifiche di disconnessione, paradossalmente permesse dal rimanere connessi. L'articolo si propone di contestualizzare e collocare gli studi sulla disconnessione all'interno di diversi contesti sociali, politici, culturali e geografici.This article investigates online connection and disconnection practices among migrants and asylum seekers. It draws from an ethnography of three Sicilian reception centres that hosted migrants and asylum seekers between September and November 2020. We show how migrants, driven by different migratory motivations, enact different mobile connection and disconnection practices. We argue that these are characterised by the different affective meanings that migrants and asylum seekers attach to mobile connection and disconnection and by the different value they place on the public and private dimensions of their lives. By offering a multifaceted portrait of the mobile connection and disconnection practices of different categories of migrants, this article also contributes to: (1) media and migration studies, by showing that there are substantial differences in online connection practices and smartphone use between asylum seekers and migrants and (2) to disconnection studies, by highlighting the nuances that exist within disconnection practices among non-privileged social groups, such as migrants and asylum seekers. We show that they cannot afford to practise typically Western, urban and elitist forms of disconnection; however, they too are able to practise specific forms of disconnection, paradoxically afforded by staying connected. The article aims to contextualise and situate disconnection studies within different social, political, cultural and geographic contexts
La normativa spagnola in materia di misure di investigazione tecnologica nell’indagine penale: alcuni possibili spunti per il legislatore italiano per un approccio sistematico alla materia
No full textL’autrice esamina la normativa introdotta nel 2015 dal legislatore spagnolo in materia di misure di
investigazione tecnologica nell’indagine penale. Particolare attenzione viene dedicata all’analisi
delle disposizioni comuni sugli atti di indagine tecnologicamente avanzati, che rappresentano il
risultato di uno sforzo normativo finalizzato a realizzare due esigenze: ridurre il rischio di obsole-
scenza della relativa disciplina e assicurare la proporzionalità dell’intrusione dei pubblici poteri nel
diritto al rispetto della vita privata dei soggetti coinvolti nell’accertamento penale.The author examines the discipline introduced in 2015 by the Spanish legislator on technological investigation tools in the criminal proceeding. Particular attention is paid to the analysis of the common provisions on technologically advanced investigations, which represent the result of a regulatory effort aimed at achieving two objectives: the reduction of the risk of regulatory obsolescence and the proportionality of the intrusion of public authorities in the right to respect for private life

La disponibilità esclusiva del dato informatico: una nuova pronuncia della Corte di cassazione a tutela del “patrimonio informativo”
No full textThe Court of cassation deals again with the issue of the interest in challenging the seizure of
computer data in case of realization of a copy and return of the originals. In accordance with the dominant case law,
the decision reiterates the admissibility of the challenge when the appellant demonstrates his interest in the
exclusive possession of the data; however, innovating with respect to the previous case law, it concludes that this
demonstration is superfluous when data are stored in devices intended by their nature to contain confidential
information. The author focuses on the reasons why this conclusion is the consequence of a paradigmatic change in
the protection of individuals’ privacy in the use of information technology
Velocity gradients choice affecting seismic site response in deep alluvial basins: Application to the Venetian Plain (Northern Italy)
No full textThe average shear-wave velocity of the first 30 metres of subsoil and the depth of the engineering bedrock are considered the key parameters for simplified seismic site response modelling. However, a reliable estimate of the site amplification should consider the entire shear-wave velocity profile from the ground surface down to the engineering bedrock. In deep alluvial basins, a typical geological context where the soil-bedrock interface may lie below the penetration depth of most common prospecting methods, only the shallow velocity profile can be defined in detail, while the deeper structures are commonly extrapolated with linear equations. The choice of a realistic interpolation between the shallow and deep soil still remains an open issue. We compute the 1D seismic site response of two sectors of the Venetian Plain (Northern Italy) characterised by gravelly and sandy deep formations. We model the 1D soil columns using theoretical non-linear gradients proposed in literature for deep alluvial basins. The numerical modelling results, in terms of strong motion parameters, show variations in the seismic site response up to 20%. The effect of the velocity gradients is also evaluated comparing the numerical simulations with real accelerometers recorded by a deep borehole seismometer and a seismic station located at the top of the borehole. These results demonstrate that the selection of the velocity gradient is crucial for seismic site characterisation of deep alluvial basins. In particular, the study suggests which is the most conservative gradient among the ones tested in terms of ground motion hazard estimation
La disciplina delle prove nel procedimento penale de societate
No full textThe Author analyses the law of evidence relevant in corporate criminal cases, with the intent to clarify the exegetic doubts related to the absence of a specific regulation of the matter in d. lg. 8 June 2001, n. 231. The controversial applicability of the ordinary rules of the code of criminal procedure is specifically addressed in the light of the compatibility clause provided by the article 34 of the Decree. The last part of the paper is dedicated to the unsettled topic of the right to silence of legal person and to the exegetic debate related to the article 44 of the Decree. Provision which, according to law doctrine, appears to restrict, far beyond the Constitutional limits, the difensive rights of the legal person. In a comparative perspective, the A. analyses French regulation and case law, with the intent to offer to the internal debate some new standpoints for further speculations
