Human Rights & Security: Justifying Exceptions

2017

Since its introduction in the 1990s1, the concept of securitization has received widespread attention well beyond the field of international relations in the context of which it first appeared. The concept indicates the discursive process in which: (i) an agent claims (securitization move) the necessity to adopt exceptional measures which bring about serious violations of otherwise binding rules, in order to protect a certain value from a grave and extraordinary threat, with the scope of convincing a specific audience to accept those measures and the violations to follow; (ii) the move is successful and the audience effectively accepts the exceptional measures (securitization). One of the p…

Corporate Governance of Banks after the Financial Crisis - Theory, Evidence, Reforms

2010

Poor corporate governance of banks has increasingly been acknowledged as an important cause of the recent financial crisis. Given the developments since the Asian financial crisis in 1997, this fact is not readily to be explained. Listed banks and even non-listed firms worldwide have publicly emphasized that good corporate governance is of vital concern for the company, and have adopted firm-specific corporate governance codices. Moreover, banking supervisors have taken up the issue. In particular, the Basel Committee on Banking Supervision has already published two editions of a guideline entitled “Enhancing corporate governance for banking organisations” which perfectly reflects the super…

La regolazione della cybersecurity in Italia

2023

Il saggio offre una panoramica generale della regolazione e dell'organizzazione della sicurezza cibernetica in Italia. In particolare, dopo una premessa volta a dedicare alcuni cenni all'evoluzione della materia e alla disciplina europea, l'elaborato si sofferma sullo stato dell'arte e sulle future sfide in materia di cybersecurity.

Libre circulación de inversiones en la Unión Europea en tiempos de COVID-19

2020

Las inversiones extranjeras han fluido como nunca durante las últimas décadas, en el marco de una aceptación generalizada de sus beneficios. Esta situación, sin embargo, comienza a alterarse de forma acelerada en múltiples lugares del planeta. La presencia de un entorno geoestratégico más complejo y la aproximación crítica de muchos Estados hacia la globalización y lo que ella significa, está consolidando una visión más cautelosa hacia la libre circulación de inversiones extranjeras que, entre otros efectos, se plasma en la elaboración de normativas más restrictivas. La Unión Europea es un espacio económicamente integrado, muy abierto a las inversiones extranjeras y dotado además, de una po…

A Spatial-Temporal Correlation Approach for Data Reduction in Cluster-Based Sensor Networks

2019

International audience; In a resource-constrained Wireless Sensor Networks (WSNs), the optimization of the sampling and the transmission rates of each individual node is a crucial issue. A high volume of redundant data transmitted through the network will result in collisions, data loss, and energy dissipation. This paper proposes a novel data reduction scheme, that exploits the spatial-temporal correlation among sensor data in order to determine the optimal sampling strategy for the deployed sensor nodes. This strategy reduces the overall sampling/transmission rates while preserving the quality of the data. Moreover, a back-end reconstruction algorithm is deployed on the workstation (Sink)…

Degradation of silica particles functionalised with essential oil components under simulated physiological conditions

2020

[EN] In this work, the biodurability of three silica particle types (synthetic amourphous silica, MCM-41 microparticles, MCM-41 nanoparticles) functionalised with three different essential oil components (carvacrol, eugenol, vanillin) was studied under conditions that represented the human gastrointestinal tract and lysosomal fluid. The effect of particle type, surface immobilised component and mass quantity on the physico-chemical properties of particles and silicon dissolution was determined. Exposure to biological fluids did not bring about changes in the zeta potential values or particle size distribution of the bare or functionalised materials, but the in vitro digestion process partia…

Monitoring wireless sensor networks through logical deductive processes

2006

This paper proposes a distributed multi-agent architecture for wireless sensor networks management, which exploits the dynamic reasoning capabilities of the Situation Calculus in order to emulate the reactive behavior of a human expert to fault situations. The information related to network events is generated by tunable agents installed on the network nodes and is collected by a logical entity for network managing where it is merged with general domain knowledge, with the aim of identifying the root causes of faults, and deciding on reparative actions. The logical inference system has being devised to carry out automated isolation, diagnosis, and, whenever possible, repair of network anoma…

Systemic approach of the links between urban dynamics, life environment and insecurity : situational prevention as a tool and stake of urban sustaina…

2008

International audience; Managing and controlling city whilst guaranteeing the social cohesion and the life quality is an objective of the urban sustainable development. Thus, the life environments and urban atmospheres that include a security dimension imply a geographical and town-planning thinking. These research activities concern the importance the city-dweller attributes to the security issues. Insecurity can sometimes explain some places repellentness and consequently the daily and residential mobilities. These displacements impact on the places economic and social functioning. Urban insecurity produces negative externalities that can be quantified. Aware of the differential attractiv…

An assessment of energy vulnerability in Small Island Developing States

2020

Abstract Small Island Developing States (SIDS) suffer from several structural characteristics that jeopardize their ability to achieve a sustainable energy future. Their reliance on imported fossil fuels exacerbates their exposure to external threats on international energy markets. Their energy systems are also exposed to internal disturbances that disrupt the proper production, transmission and distribution of energy. The aim of this paper is to investigate the extent to which island energy systems are vulnerable to shocks and internal dysfunctions over which they have no control. For this purpose, we build a composite index of energy vulnerability using the Multi-Layer Benefit-of-the-Dou…
