La rinascita della guerra giusta

Il concetto di “guerra giusta” figura in una serie di riflessioni nel diritto internazionale e viene riferita all’uso legittimo della forza militare, così come è previsto nella Carta delle Nazioni Unite. Rinasce dalle sfide della storia contemporanea e possiamo coglierne i significati soltanto analizzando alcuni contesti storici nei quali ricorre e svelando, a partire da questi, le ragioni e i limiti della sua reviviscenza. Sebbene la guerra sia stata messa al bando dopo la seconda guerra mondiale, se escludiamo la guerra del Vietnam, non possiamo dimenticare orrori recenti per cui le forze occidentali sono dovute intervenire: massacri e pulizia etnica in Bosnia e Kosovo, Ruanda, Sudan, Sie…

Risk assessment of component failure modes and human errors using a new FMECA approach: application in the safety analysis of HDR brachytherapy

2014

Failure mode, effects and criticality analysis (FMECA) is a safety technique extensively used in many different industrial fields to identify and prevent potential failures. In the application of traditional FMECA, the risk priority number (RPN) is determined to rank the failure modes; however, the method has been criticised for having several weaknesses. Moreover, it is unable to adequately deal with human errors or negligence. In this paper, a new versatile fuzzy rule-based assessment model is proposed to evaluate the RPN index to rank both component failure and human error. The proposed methodology is applied to potential radiological over-exposure of patients during high-dose-rate brach…

Safety study of an LNG regasification plant using an FMECA and HAZOP integrated methodology

2015

Abstract A safety analysis was performed to determine possible accidental events in the storage system used in the liquefied natural gas regasification plant using the integrated application of failure modes, effects and criticality analysis (FMECA) and hazard and operability analysis (HAZOP) methodologies. The goal of the FMECA technique is the estimation of component failure modes and their major effects, whereas HAZOP is a structured and systematic technique that provides an identification of the hazards and the operability problems using logical sequences of cause-deviation-consequence of process parameters. The proposed FMECA and HAZOP integrated analysis (FHIA) has been designed as a …

Assessment of the interpretability of data mining for the spatial modelling of water erosion using game theory

2021

Abstract This study undertook a comprehensive application of 15 data mining (DM) models, most of which have, thus far, not been commonly used in environmental sciences, to predict land susceptibility to water erosion hazard in the Kahorestan catchment, southern Iran. The DM models were BGLM, BGAM, Cforest, CITree, GAMS, LRSS, NCPQR, PLS, PLSGLM, QR, RLM, SGB, SVM, BCART and BTR. We identified 18 factors usually considered as key controls for water erosion, comprising 10 factors extracted from a digital elevation model (DEM), three indices extracted from Landsat 8 images, a sediment connectivity index (SCI) and three other intrinsic factors. Three indicators consisting of MAE, MBE, RMSE, and…

Spectral Density Estimate for Stable Processes Observed with an Additive Error

2018

International audience; In this paper, a symmetric alpha stable process where its spectral representation has an additive error is considered. The error is supposed to be constant. A periodogram as estimator of the spectral density and its rate of convergence are given. In order to give an asymptotically unbiased and consistent estimate of the spectral density, this periodogram is smoothed by an adapted spectral window. The rate of convergence is given.

The medico-legal implications in medical malpractice claims during Covid-19 pandemic: Increase or trend reversal?

2020

The Covid-19 pandemic caused a marked increase in admissions to intensive care units. The critically ill patients’ condition from the infection resulted in their deaths. The healthcare facilities have got into trouble because of the pandemic. In fact, they had to create additional beds in a very short time and to protect health workers with personal protective equipment. Healthcare professionals fear that there will be an increase in complaints and medico-legal malpractice claims and hence they have urged politicians to discuss this. The Italian Parliament recently debated the topic of medical liability and passed the Decree-Law no. 18 of 17 March 2020 (DL – so called Cura Italia) by which…

Empire and Democracy. A critical reading of Michael Ignatieff

2013

Empires expand their hegemony combined two contrasting forces; one is violence the second is characterized by persuasion. Ideology works in these contexts, as an efficient instrument of self-indoctrination whereby dominated cultures accept the cultural matrix of empire. In this vein, the present essay-review not only questions the employment of human rights in the liberal thought, but also tries to respond to the conceptual problems of liberalism to understand terrorism. Based on two seminal texts written by the liberal Michael Ignatieff, we formulate the thesis that liberalism supports the war against terror because of its doctrine of self-determination.
