Il ruolo del white paper sulle offerte al pubblico di cripto-attività alla luce della proposta MiCA

2022

La proposta MiCA, nel regolare il white paper sulle offerte di crypto-assets, sembra tenere in considerazione i benefici e i limiti dei sistemi di voluntary e di mandatory disclosure, non optando integralmente né per il primo, né per il secondo. In quest’ottica, se può condividersi l’approccio regolamentare diretto a graduare, a seconda della tipologia di token offerto, sia il contenuto che l’assoggettamento del documento a mera notifica o ad approvazione ex ante da parte dell’Autorità competente, dubbi sorgono in ordine all’indistinta allocazione dell’onere della prova in capo all’oblato, nei casi di violazione della disciplina del relativo white paper.

The MiCa proposal in the regular white paper on crypto-assets offerings seems to take into account the benefits and limitations of voluntary and mandatory disclosure systems not opting for either the former or the latter in full. On one hand one can agree with the regulatory approach aimed at adapting the content of the white paper to the type of token offered and at making the white paper either subject to mere notification or to the approval by the competent Authority depending on the asset offered. On the other hand doubts arise on the indistinct allocation of the burden of proof to the user in case of infringement of the relevant white paper framework.Settore IUS/04 - Diritto Commerciale

La recente riforma della disciplina italiana del subappalto nella prospettiva del bid rigging

2023

L’articolo analizza in chiave critica la disciplina nazionale del subappalto nell’ambito delle gare pubbliche, così come recentemente riformata a seguito di diversi interventi normativi in ottemperanza alla procedura d’infrazione avviata dalla Commissione UE. Stando alla tesi dell’A., l’attuale quadro normativo – caratterizzato dalla quasi totale eliminazione delle limitazioni previgenti (probabilmente anche spingendosi oltre ciò che la Commissione UE ha richiesto) – difetta nel trovare un equo bilanciamento tra il principio della massima partecipazione alla gara, da un lato, e l’esigenza di prevenire e svelare potenziali condotte collusive, dall’altro. La suddetta conclusione, peraltro, ap…

The article critically analyzes the Italian regulation of subcontracting in the context of public tenders as recently amended by several legislative measures in compliance with the infringement procedure launched by the European Commission against Italy. According to the Author’s view the current legislative framework – characterized by the almost overall elimination of the previous limits (probably even going beyond what the European Commission requested) – lacks in finding a fair balance between the principle of the maximum participation in the tender on the one hand and the need to prevent and reveal potential collusive conduct on the other. Furthermore this conclusion is supported by the analysis of the regulation of the causes of exclusion from the tender still too timid in envisaging the optional exclusion of the participants due to anticompetitive conduct.

La Seconda Vita dell'Ambiente Costruito

2021

Il contributo inquadra i saggi, gli studi, le ricerche e progetti pubblicati sul numero 9 di AGATHÓN su ‘La Seconda Vita dell’Ambiente Costruito’, tema di interesse per il mondo accademico, delle professioni e dell’industria. Cambiamenti climatici, eccessivo consumo di suolo e di risorse non rinnovabili, produzione sempre crescente di rifiuti, emergenza pandemica e crisi socio-economica globale sono entrati di fatto nel nostro quotidiano: seppur drammatiche, per certi versi, tali questioni possono essere colte come un’opportunità per ripensare il modo e il mondo in cui viviamo. In questo contesto di ‘rivoluzione’(Floridi, 2020) e di ‘policrisi’ (Losasso, 2020), e con riferimento specifico a…

The contribution frames the essays studies research and projects published in issue 9 of AGATHÓN on ‘The SecondLife of the Built Environment’ an interesting topic for universities businesses and industry. Climate changes excessive use of soil renewable resources ever-increasing production of waste the current pandemic emergency and the global socio-economic crisis have in fact entered our daily life. Even if these are tragic issues they can be somehow seized as an opportunity to rethink the way we live and our world. In this ‘revolutionary’ (Floridi 2020) and ‘polycrisis’ (Losasso 2020) context specifically referring to the building industry the Academy the Research and Industry worlds are called to give answers – based on sustainability and the principles of the Green Deal but also and mostly of the new Bauhaus – that can encourage reconsiderations and re-orientations of processes and products new projects on places buildings objects and materials able to positively affect the governance of the global change that our planet and humanity need able to give a ‘new life’ to the built and/or transformed environment at any scaleSettore ICAR/12 - Tecnologia Dell'Architettura

Tutela e sicurezza del lavoro tra centro e periferia: la sicurezza sui luoghi di lavoro

2013

Il saggio prende in esame la complessa questione del riparto di competenze tra Stato e Regioni alla luce del Titolo V della Costituzione in materia di salute e sicurezza sui luoghi di lavoro. Il riparto di competenze tra centro e periferia è stato oggetto di una limitata analisi da parte della dottrina e della giurisprudenza, che si sono concentrate in particolare sulla disciplina del mercato del lavoro. L’Autore descrive un sistema multilivello, caratterizzato dalla compresenza di fonti nazionali e regionali, della contrattazione collettiva, nonché di codici di condotta. Sulla scorta di una ricostruzione del quadro normativo e dei percorsi della giurisprudenza, il saggio propone una lettur…

The essay examines the complex issue of the division of powers between the State and the Regions according to Title V of the Constitution concerning health and safety at workplace. This division between the center and the periphery has been subject to a limited review by doctrine and jurisprudence expecially focusing on the regulation of labour market. The Author describes a multilevel system characterized by the presence of national and regional sources collective bargaining and codes of conduct. On the basis of a reconstruction of the regulatory framework and the judicial statements the paper proposes a dynamic reading of the relationship between center and periphery in which the axis of the system remains however anchored to the national jurisdiction along with important regulatory issues left to the regional legislation.Settore IUS/07 - Diritto Del Lavoro

Electronic properties of graphene: A learning path for undergraduate students

2016

The purpose of this work is to present a learning path aimed at deepening student understanding of the fundamental concepts underlying the electronic properties of new materials, graphene in particular. To achieve this task, we propose a five-week long workshop where students may be introduced to fundamental concepts of advanced physics, rarely used in learning paths, such as the symmetry properties of the crystal lattice, the group theory , the features of the free electron wave functions and energy levels, the relativistic Dirac equation. Particular emphasis is given to the manner of introducing these concepts, since an essential knowledge of solid state physics, quantum physics and relat…

Elucidating Gating Effects for Hydrogen Sorption in MFU-4-Type Triazolate-Based Metal-Organic Frameworks Featuring Different Pore Sizes

2011

A highly porous member of isoreticular MFU-4-type frameworks, [Zn(5)Cl(4)(BTDD)(3)] (MFU-4l(arge)) (H(2)-BTDD=bis(1H-1,2,3-triazolo[4,5-b],[4',5'-i])dibenzo[1,4]dioxin), has been synthesized using ZnCl(2) and H(2)-BTDD in N,N-dimethylformamide as a solvent. MFU-4l represents the first example of MFU-4-type frameworks featuring large pore apertures of 9.1 Å. Here, MFU-4l serves as a reference compound to evaluate the origin of unique and specific gas-sorption properties of MFU-4, reported previously. The latter framework features narrow-sized pores of 2.5 Å that allow passage of sufficiently small molecules only (such as hydrogen or water), whereas molecules with larger kinetic diameters (e.…

A tris-oxovanadium pyrogallate complex: synthesis, structure, and magnetic and electronic properties

2021

International audience; With the aim of identifying new cation-phenolate complexes, we herein investigated the reactivity of pyrogallol (H(3)pgal) with vanadium salts. A trimetallic anionic complex was identified, and found to be formed under a broad set of reaction conditions. This complex, with the formula V3O3(pgal)(3)(3-), consists of three oxovanadium(iv) units connected together by three pyrogallate ligands to afford a bowl-shaped species presenting a pseudo 3-fold symmetry axis. Its crystal structure is reported, as well as its characterisation by a broad set of techniques, including powder X-ray diffraction, thermogravimetric analysis, infrared and Raman spectroscopy, and solid stat…

Coordination Driven Capture of Nicotine Inside a Mesoporous MOF.

2017

Metal organic frameworks (MOFs) are a wide class of crystalline porous polymers studied in many fields, ranging from catalysis to gas storage. In the past few years, MOFs have been studied for the encapsulation of organic or organometallic molecules and for the development of potential drug carriers. Here, we report on the study of two structurally-related mesoporous Cu-MOFs, namely PCN-6 and PCN-6′ (PCN stands for Porous Coordination Network), for nicotine trapping. Nicotine is a well-known alkaloid liquid molecule at room temperature, whose crystalline structure is still unknown. In this work, the loading process was monitored by electron ionization mass spectrometry by using a direct ins…

2004

In rats, two peroxisomal 3-ketoacyl-CoA thiolase genes (A and B) have been cloned, whereas only one thiolase gene is found in humans. The aim of this study was thus to clone the different mouse thiolase genes in order to study both their tissue expression and their associated enzymatic activity. In this study, we cloned and characterized two mouse peroxisomal 3-ketoacyl-CoA thiolase genes (termed thiolase A and B). Both thiolase A and B genes contain 12 exons and 11 introns. Using RNA extracted from mouse liver, we cloned the two corresponding cDNAs. Thiolase A and B cDNAs possess an open reading frame of 1272 nucleotides encoding a protein of 424 amino acids. In the coding sequence, the tw…
