'Aedes sacrae' e 'edifici destinati all'esercizio pubblico del culto cattolico': la condizione giuridica delle chiese in Italia tra diritto canonico e ordinamento statale

Già ad uno sguardo esterno la normativa chiamata a disciplinare la condizione giuridica delle chiese cattoliche nel nostro Paese appare caratterizzata da un elevato grado di complessità: impressione che trova conferma sia con riferimento al diritto canonico, nella cui prospettiva le disposizioni appositamente dedicate ai 'loca sacra' dal Codex Iuris Canonici richiedono di essere affiancate dalle indicazioni provenienti – ai rispettivi, differenti livelli – tanto dalla Conferenza Episcopale Italiana quanto dai dicasteri della Curia romana; sia nell'ottica dell'ordinamento italiano, che agli 'edifici destinati all’esercizio pubblico del culto cattolico' riserva un'attenzione specifica, emergente nella legislazione unilaterale così come in quella pattizia. A fronte di una simile eterogeneità, sono d’altra parte note le problematiche che il tempo presente pone innanzi alle esigenze di una corretta amministrazione del patrimonio ecclesiastico – spesso pure dotato di un inestimabile valore storico-artistico –, le quali si riversano sulla preservazione stessa di tali immobili. Prendendo le mosse da questi presupposti, la trattazione si propone di effettuare una lettura sistematica delle diverse fasi in cui si articola il 'ciclo vitale' di un'ipotetica chiesa cattolica, così da ricostruire organicamente e criticamente quel quadro complessivo che permetta di formulare le soluzioni più appropriate per rispondere a questioni risalenti e sfide inedite. È quindi con questo intento che, una volta definito esattamente il concetto di chiesa-edificio, vengono ripercorsi i momenti in cui si sviluppa, anche giuridicamente, la sua esistenza: dalla pianificazione al finanziamento delle nuove costruzioni, con una speciale attenzione all'apporto che può essere offerto da parte della CEI; dagli utilizzi ammessi nel diritto canonico alle tutele garantite da parte statale; dalle misure di salvaguardia ai criteri per la loro adeguata gestione, comprendenti tanto i profili relativi alla conservazione quanto quelli riguardanti la valorizzazione; dalle implicazioni di un'eventuale riduzione a uso profano fino ai requisiti dettati per la nuova destinazione dell'immobile.

Numerical simulations of magma chamber dynamics at Campi Flegrei, and associated seismicity, deformation and gravity changes

Understanding the complex relationships between quantities measured by volcanic monitoring network and shallow magma processes is a crucial headway for the comprehension of volcanic processes and a more realistic evaluation of the associated hazard. This question is very relevant at Campi Flegrei, a volcanic quiescent caldera immediately north-west of Napoli (Italy). The system activity shows a high fumarole release and periodic ground slow movement (bradyseism) with high seismicity. This activity, with the high people density and the presence of military and industrial buildings, makes Campi Flegrei one of the areas with higher volcanic hazard in the world. In such a context my thesis has been focused on magma dynamics due to the refilling of shallow magma chambers, and on the geophysical signals detectable by seismic, deformative and gravimetric monitoring networks that are associated with this phenomenologies. Indeed, the refilling of magma chambers is a process frequently occurring just before a volcanic eruption; therefore, the faculty of identifying this dynamics by means of recorded signal analysis is important to evaluate the short term volcanic hazard. The space-time evolution of dynamics due to injection of new magma in the magma chamber has been studied performing numerical simulations with, and implementing additional features in, the code GALES (Longo et al., 2006), recently developed and still on the upgrade at the Istituto Nazionale di Geofisica e Vulcanologia in Pisa (Italy). GALES is a finite element code based on a physico-mathematical two dimensional, transient model able to treat fluids as multiphase homogeneous mixtures, compressible to incompressible. The fundamental equations of mass, momentum and energy balance are discretised both in time and space using the Galerkin Least-Squares and discontinuity-capturing stabilisation technique. The physical properties of the mixture are computed as a function of local conditions of magma composition, pressure and temperature.The model features enable to study a broad range of phenomenologies characterizing pre and sin-eruptive magma dynamics in a wide domain from the volcanic crater to deep magma feeding zones. The study of displacement field associated with the simulated fluid dynamics has been carried out with a numerical code developed by the Geophysical group at the University College Dublin (O’Brien and Bean, 2004b), with whom we started a very profitable collaboration. In this code, the seismic wave propagation in heterogeneous media with free surface (e.g. the Earth’s surface) is simulated using a discrete elastic lattice where particle interactions are controlled by the Hooke’s law. This method allows to consider medium heterogeneities and complex topography. The initial and boundary conditions for the simulations have been defined within a coordinate project (INGV-DPC 2004-06 V3_2 “Research on active volcanoes, precursors, scenarios, hazard and risk - Campi Flegrei”), to which this thesis contributes, and many researchers experienced on Campi Flegrei in volcanological, seismic, petrological, geochemical fields, etc. collaborate. Numerical simulations of magma and rock dynamis have been coupled as described in the thesis. The first part of the thesis consists of a parametric study aimed at understanding the eect of the presence in magma of carbon dioxide in magma in the convection dynamics. Indeed, the presence of this volatile was relevant in many Campi Flegrei eruptions, including some eruptions commonly considered as reference for a future activity of this volcano. A set of simulations considering an elliptical magma chamber, compositionally uniform, refilled from below by a magma with volatile content equal or dierent from that of the resident magma has been performed. To do this, a multicomponent non-ideal magma saturation model (Papale et al., 2006) that considers the simultaneous presence of CO2 and H2O, has been implemented in GALES. Results show that the presence of CO2 in the incoming magma increases its buoyancy force promoting convection ad mixing. The simulated dynamics produce pressure transients with frequency and amplitude in the sensitivity range of modern geophysical monitoring networks such as the one installed at Campi Flegrei . In the second part, simulations more related with the Campi Flegrei volcanic system have been performed. The simulated system has been defined on the basis of conditions consistent with the bulk of knowledge of Campi Flegrei and in particular of the Agnano-Monte Spina eruption (4100 B.P.), commonly considered as reference for a future high intensity eruption in this area. The magmatic system has been modelled as a long dyke refilling a small shallow magma chamber; magmas with trachytic and phonolitic composition and variable volatile content of H2O and CO2 have been considered. The simulations have been carried out changing the condition of magma injection, the system configuration (magma chamber geometry, dyke size) and the resident and refilling magma composition and volatile content, in order to study the influence of these factors on the simulated dynamics. Simulation results allow to follow each step of the gas-rich magma ascent in the denser magma, highlighting the details of magma convection and mixing. In particular, the presence of more CO2 in the deep magma results in more ecient and faster dynamics. Through this simulations the variation of the gravimetric field has been determined. Afterward, the space-time distribution of stress resulting from numerical simulations have been used as boundary conditions for the simulations of the displacement field imposed by the magmatic dynamics on rocks. The properties of the simulated domain (rock density, P and S wave velocities) have been based on data from literature on active and passive tomographic experiments, obtained through a collaboration with A. Zollo at the Dept. of Physics of the Federici II Univeristy in Napoli. The elasto-dynamics simulations allow to determine the variations of the space-time distribution of deformation and the seismic signal associated with the studied magmatic dynamics. In particular, results show that these dynamics induce deformations similar to those measured at Campi Flegrei and seismic signals with energies concentrated on the typical frequency bands observed in volcanic areas. The present work shows that an approach based on the solution of equations describing the physics of processes within a magmatic fluid and the surrounding rock system is able to recognise and describe the relationships between geophysical signals detectable on the surface and deep magma dynamics. Therefore, the results suggest that the combined study of geophysical data and informations from numerical simulations can allow in a near future a more ecient evaluation of the short term volcanic hazard.

L'evoluzione della tutela cautelare nel processo amministrativo

L’effettività della tutela cautelare, intesa come tutela tempestiva, adeguata e piena, è stata la linea cardine dell’evoluzione della giustizia amministrativa, che, nel corso di un periodo durato più di un secolo, grazie all’opera della giurisprudenza e della dottrina, si è strutturata oggi su un vero processo. Approdo recente, e allo stesso tempo, simbolo di questa evoluzione, è sicuramente il Codice del processo amministrativo emanato con il d. lgs. 2 luglio 2010, n. 104. La ricerca, di cui questo contributo costituisce un resoconto, è iniziata contestualmente all’entrata in vigore del nuovo testo, e quindi è stata anche l’occasione per vederne le prime applicazioni giurisprudenziali. In particolare la lettura del Codice, prescindendo da una mera ricognizione di tutto il suo lungo articolato, è stata fatta alla luce di una ponderazione, nell’attualità, non solo del principio di effettività, ma anche del principio di strumentalità che lega tradizionalmente la fase cautelare con la fase di merito. I risultati della ricerca manifestano la volontà del legislatore di confermare questo rapporto strumentale, per fronteggiare una deriva incontrollata verso una cautela dagli effetti alle volte irreversibili, quale verificatasi nell’applicazione giurisprudenziale, ma contestualmente evidenziano la volontà di estendere la portata della tutela cautelare. Guardando a cosa sia diventata oggi la tutela cautelare, si è assistito ad un rafforzamento degli effetti conformativi, tipici delle sentenze di merito ma che si sono estesi alla fase cautelare. I giudici, pur consapevoli che la tutela cautelare non sia una risposta a cognizione piena, bensì sommaria, intendono comunque garantire una tutela tempestiva ed effettiva, anche per il tramite di tecniche processuali particolari, come quella del remand, cui, all’interno della ricerca, viene dedicato ampio spazio. Nella sua ultima parte la ricerca si è focalizzata, sempre volendo guardare in maniera globale agli effetti della tutela cautelare, sul momento dell’esecuzione e quindi sul giudizio di ottemperanza.

The psychoactive effects of “Light Cannabis”. From Italian law to psychopharmacology

In 2019, the Italian Supreme Court established that hemp, for non-medical use, cannot be commercialized for human use, when the “psychotropic effect” of the product or its “offensiveness” can be demonstrated. The first chapter of this work reports a review of the European and Italian legislation on hemp cultivation, as well as the hemp production chain and commercial activities. The second chapter reports the pharmacological aspects and the psychoactive effects of light cannabis, along with pharmacokinetics of the main Cannabis compounds: Δ9-tetrahydrocannabinol (Δ9-THC), Cannabidiol (CBD) and Cannabinol (CBN). The aim of the experimental study, reported in the third chapter, is to assess Δ9-THC and CBD blood concentrations after smoking “light cannabis”, and its effects on vigilance, cognitive and motor skills. Eighteen young adults consumed three light cannabis cigarettes with a percentage of 0.41% of Δ9-THC and of 12.41% of CBD. Blood samples were collected before the experiment (t0) and after pre-defined time-lapses. Five performance tasks and a subjective scale were employed for measuring cognitive and psychomotor performances the day before the experiment (TT0) and after the third cigarette (TT1). Mean (SD) concentrations (ng/ml) were between 1.0(0.8) in t1 and 0.3(0.3) in t5 for Δ9-THC; and 10.5(10.3) in t1 and 5.7(5.7) in t5 for CBD. No significant differences were observed between TT0 and TT1 for all performed psychomotor performance task. Δ9-THC and CBD concentrations showed a high inter-subject variability, and the average concentrations were lower than those previously reported. Toxicological results showed a decrease of Δ9-THC and CBD after the third light cannabis cigarette, and a Δ9-THC /CBD ratio always < 1 was observed. This value might be useful in discriminating light cannabis versus illegal/medical cannabis consumption. The lack of impairment observed in our participants can be interpreted as a consequence of the very low concentrations in the blood.

An analysis of the regulatory chill hypothesis: environmental protection in international investment law

The goal of this thesis has been to find out whether ISDS and international investment law exert a chilling effect on more stringent environmental standards at the domestic level. Due to the lack of consistent empirical and statistical evidence uncovered during the analysis, this thesis largely dismisses the regulatory chill hypothesis. However, two exceptions are identified: first, there is evidence of the efforts made by domestic industrial groups and trade unions to prevent the implementation of stricter environmental standards; second, it has become apparent that unfounded beliefs, e.g. about ISDS, held by lawmakers and regulators can play an important role in chilling stricter environmental standards. For these reasons, a new and narrower definition of the regulatory chill phenomenon has been proposed, one that only encompasses those instances in which lawmakers, governments and government agencies refrain from adopting the laws and regulations that they deem the most appropriate because they believe that doing so would lead to adverse consequences at the international trade and investment level, despite a lack of consistent and robust evidence supporting their concerns. The second part of this thesis focusses on what could be done in international economic law to promote environmentally friendly FDI, while preventing the few instances in which regulatory chill may take place due to ill-founded beliefs held by lawmakers and regulators. Following an analysis that highlights the paramount role played by public participation and responsive institutions to achieve an appropriate level of environmental protection, this study ends with a proposal that recommends the adoption of a clause within IIAs that makes pre-investment environmental screening mandatory and free from ISDS oversight.

Big data and AI applications for health and research. Co-regulation mechanisms as a prosed solution for data protection law issues

Big data and AI are paving the way to promising scenarios in clinical practice and research. However, the use of such technologies might clash with GDPR requirements. Today, two forces are driving the EU policies in this domain. The first is the necessity to protect individuals’ safety and fundamental rights. The second is to incentivize the deployment of innovative technologies. The first objective is pursued by legislative acts such as the GDPR or the AIA, the second is supported by the new data strategy recently launched by the European Commission. Against this background, the thesis analyses the issue of GDPR compliance when big data and AI systems are implemented in the health domain. The thesis focuses on the use of co-regulatory tools for compliance with the GDPR. This work argues that there are two level of co-regulation in the EU legal system. The first, more general, is the approach pursued by the EU legislator when shaping legislative measures that deal with fast-evolving technologies. The GDPR can be deemed a co-regulatory solution since it mainly introduces general requirements, which implementation shall then be interpretated by the addressee of the law following a risk-based approach. This approach, although useful is costly and sometimes burdensome for organisations. The second co-regulatory level is represented by specific co-regulatory tools, such as code of conduct and certification mechanisms. These tools are meant to guide and support the interpretation effort of the addressee of the law. The thesis argues that the lack of co-regulatory tools which are supposed to implement data protection law in specific situations could be an obstacle to the deployment of innovative solutions in complex scenario such as the health ecosystem. The thesis advances hypothesis on theoretical level about the reasons of such a lack of co-regulatory solutions.
