Il rapporto tra andamento dell’economia e infiltrazione della criminalità organizzata nel mercato economico legale:un’analisi della realtà lombarda
No full textQuanto influisce la criminalità organizzata sull’economia del nostro Paese?
Studi recenti mostrano che la criminalità organizzata tende a proporsi come istituzione che opera, in un dato territorio, oltre che come governo del mondo criminale, per proiettare il suo potere di controllo sulla sfera dell'agire legale, ricorrendo alla violenza e alla corruzione, o intessendo relazioni di tipo cooperativo.
Tra le relazioni che la criminalità organizzata stabilisce con il mondo della legalità, sicura importanza rivestono quelle di tipo economico.
Il nesso che lega l'economia legale alla criminalità organizzata è duplice: a) rapporti che si instaurano per effetto della domanda - proveniente dall'economia legale - di beni e servizi illegali; b) rapporti che hanno per oggetto il reinvestimento nell'economia legale dei profitti conseguiti nei mercati illegali.
Questa seconda relazione pone, come questione cruciale nello studio degli effetti economici della criminalità organizzata, l'infiltrazione delle organizzazioni criminali nell'economia legale.
Diversi sono i fini che spingono la criminalità verso l’economia legale: la necessità di mascherare l'attività criminale; la ricerca di investimenti redditizi; l'esigenza di rafforzare il controllo del territorio; la convenienza a intervenire nei mercati legali utilizzando il vantaggio competitivo costituito dall'ampia disponibilità di profitti illeciti.
La zona grigia in cui il crimine organizzato e l'attività d'impresa s'incontrano e si sovrappongono ha confini continuamente mutevoli ed è osservazione condivisa che l’ampliarsi di tale area provoca gravi distorsioni nei sistemi economici nazionali alterando i meccanismi fisiologici di allocazione delle risorse e la concorrenza, a tacere delle conseguenze riconducibili all’assuefazione a comportamenti illegali.
Lo scopo di questo scritto è quello di cercare di indagare le dinamiche economiche di organizzazioni criminali di stampo mafioso nel tentativo di far emergere “quel tessuto criminale e le sue risorse che inquinano ampiamente l’economia, la politica e la vita del paese, riducendo il potenziale di sviluppo umano, civile ed economico

Facing the pandemic with a smile: the case of Memedical and its impact on cardiovascular professionals
No full textSince its outbreak, the Coronavirus disease 2019 (COVID-19) has profoundly changed the world we were acquainted with. After the first known contact with humankind in Wuhan, China, in December 2019, the reckless spread of such pathogen put the healthcare system to the test, leading to harmful consequences affecting human lives in every aspect. As of February 2022, the death toll amounts to almost 6 million deaths, but the pathogenic profile of SARS-CoV-2 goes way beyond the mere biological interaction between the viral particle and our organism. People had to deal with the severe psychological impact caused by the only available weapon to fight this infection, i.e., social distancing. The human psychological profile has been strained with repercussions we still are unaware of nowadays. Healthcare professionals were among the most hit categories, not only because of the quarantine but above all for the situations they had to bear every day, constantly facing desperation, death, isolation, and rage. In such circumstances, social media represented a powerful shelter, giving people the ability to keep in contact and to feel connected even if miles apart. In our country, the power of communication was strongly emphasized by launching an Italian Facebook group called "Memedical," where members can share ironic memes to feel closer and give a glimmer of happiness in such a challenging moment. Our review highlights the severity of this pandemic's impact, deteriorating the global population's physical and mental health, and shows how wise use of social media can benefit the quality of life. with a smile: the case of Memedical and its impact on cardiovascular professionals
VALIDATION OF A STATISTICAL MODEL FOR ATMOSPHERIC POLLUTION FORECAST IN A COMPLEX INDUSTRIAL AREA
No full textRapid malignant progression of an intraparenchymal choroid plexus papillomas
No full textBackground: Choroid plexus tumors (CPTs) are rare neoplasms accounting for only 0.3-0.6% of all brain tumors in adults and 2-5% in children. The World Health Organization (WHO) classification describes three histological grades: grade I is choroid plexus papilloma (CPP), grade II is atypical papilloma, and grade III is the malignant form of carcinoma. In adults, CPTs rarely have a supratentorial localization. Case Description: Here we report a very rare case of an intraparenchymal parietal CPP with a rapid histological transition from grade I to grade III WHO in a 67-year-old man, in <7 months. Conclusion: Because of the rarity of these oncotypes, descriptions of each new case are useful, mostly to consider this diagnostic entity in extraventricular brain tumors of adults, despite an unusual location
Peripheral facial palsy following ventriculoperitoneal shunt. The lesson we have learned
No full textThe most frequent complications after shunt surgery are infective and obstructive. Other types are less common, and eventually occur due to technical errors during brain ventricular puncture, opening the intraperitoneal cavity or the tunnelling of the catheter between the two points. Although rare, there are well-reported complications related to the poor positioning of the distal catheter, with perforation of organs and tissues. We report a very rare case of a male patient with normal pressure hydrocephalus submitted to ventriculoperitoneal shunt. During tunnelling of the shunt stylet, a peripheral facial palsy due to injury to the extra cranial segment of the facial nerve occurred. To the best of our knowledge this is the second case described in Literature. The patient and the surgeon should be aware of this very rare but possible complication in shunt surgery being careful to the course of the facial nerve in the mastoid region
Digital Twin of a Water Supply System Using the Asset Administration Shell
No full textThe concept of digital twins is one of the fundamental pillars of Industry 4.0. Digital twin allows the realization of a virtual model of a real system, enhancing the relevant performance (e.g., in terms of production rate, risk prevention, energy saving, and maintenance operation). Current literature presents many contributions pointing out the advantages that may be achieved by the definition of a digital twin of a water supply system. The Reference Architecture Model for Industry 4.0 introduces the concept of the Asset Administration Shell for the digital representation of components within the Industry 4.0 ecosystem. Several proposals are currently available in the literature considering the Asset Administration Shell for the realization of a digital twin of real systems. To the best of the authors’ knowledge, at the moment, the adoption of Asset Administration Shell for the digital representation of a water supply system is not present in the current literature. For this reason, the aim of this paper is to present a methodological approach for developing a digital twin of a water supply system using the Asset Administration Shell metamodel. The paper will describe the approach proposed by the author and the relevant model based on Asset Administration Shell, pointing out that its implementation is freely available on the GitHub platform
A NEW APPROACH TO JOHNSON NOISE THERMOMETRY BASED ON NOISE MEASUREMENTS ONLY
No full text Johnson Noise Thermometry (JNT) can be regarded as a quite well established technique for the evaluation of the temperature. It relays on the accurate estimation of the voltage noise across a resistor, that acts as a sensor, and on the knowledge of the resistance of the sensor itself. In order to perform a temperature measurement, therefore, the resistance of the sensor has to be measured with a high accuracy multimeter and afterwards, the voltage noise across its ends has to be estimated in the assumption that the resistance does not change with time and is independent of frequency. In this paper we present a new approach for JNT that is based on a four channel cross correlation technique that allows, at least in principle, to estimate the temperature of a passive bipole from noise measurements only, as the power spectra of the current noise of the bipole and the real and imaginary part of its admittance can all be obtained from a proper elaboration of the acquired noise spectra. In particular, as the real part of the bipole admittance can be estimated as a function of the frequency, the limitation of resorting to purely resistive bipoles is also removed. Preliminary results demonstrating the effectiveness of the approach we propose are reported in this paper. The most important technical limitations that, at present, prevent the new approach to compete with the most advanced technique developed for the case of the conventional JNT are also discussed. </jats:p
