description: Strong evidence exists indicating that aerosol transmission of the novel coronavirus SARS-CoV-2 is a significant transmission modality. We experimentally evaluated the impact of ventilation on aerosol dynamics and distribution along with the effective filtration efficiency (EFE) of four different mask types, with and without mask fitters, in a classroom setting. These were used to estimate aerosol conditional infection probability using the Wells-Riley model for three scenarios with different ventilation and mask interventions. Aerosol measurements confirmed that aerosol in the room was uniform within a factor of 2 for distances >2 m from the source. Mask EFE results demonstrate that most masks fit poorly with estimated leakage rates typically >50%. However, EFEs approaching the mask material FE were achievable using mask fitters. Infection probability estimates indicate that ventilation alone is not able to achieve probabilities <0.01 (1%). The use of moderate to high EFE masks reduces infection probability, > 5x in some cases. Reductions provided by ventilation and masks are synergistic and multiplicative. The results reinforce the use of properly donned masks to achieve reduced aerosol transmission of SARS-CoV-2 and other infectious diseases and motivate improvements in the EFE of masks through improved design or use of mask fitters.
Représentations galoisiennes p-adiques et (phi,tau)-modules

Subjects: subject: Number Theory (math.NT)
subject: FOS: Mathematics

description: Let p be an odd prime number and K be a p-adic field. In this paper, we develop an analogue of Fontaine's theory of (phi,Gamma)-modules replacing the p-cyclotomic extension by the extension K_infty obtained by adding to K a compatible system of p^n-th roots of a fixed uniformizer pi of K. As a result, we obtain a new classification of p-adic representations of G_K = Gal(Kbar/K) by some (phi, τ)-modules. We then make a link between the theory of (phi,tau)-modules discussed above and the so-called theory of (phi,N_nabla)$-modules developped by Kisin. As a corollary, we answer a question of Tong Liu: we prove that, if K is a finite extension of Q_p, every representation of G_K of E(u)-finite height is potentially semi-stable.

description: L'avvento della tecnologia è paragonabile al periodo della ricostruzione del periodo post-bellico, per forza di cambiamento epocale e ricadute sulla socialità del singolo, nell'esercizio dei diritti fondamentali e delle libertà personali, nonché nei rapporti tra cittadino e Stato. Gli ultimi eventi causati dalla crisi pandemica hanno accelerato il processo di consapevolezza del fenomeno epocale: la tecnologia è direttamente strumentare allo sviluppo dei popoli. Con questo contributo si intende analizzare il fenomeno dell'utilizzo delle nuove tecnologie come facilitatori dell'esercizio dei diritti e delle libertà fondamentali, verificando se le attuali discipline in tema di neutralità della rete, identità digitali ed e-government sono confacenti ai tempi che stiamo vivendo. In particolare, si analizzeranno gli interventi messi in campo dalle istituzioni eurounitarie per realizzare un sistema unionale digitale. Inoltre si analizzerà il caso italiano per verificare l’andamento del miglioramento tecnologico dell’amministrazione digitale al servizio dei diritti e delle libertà fondamentali.

La strategia italiana per gestire l’emergenza Covid-19 e la sfida della condivisione dei poteri amministrativi
Creators: name: Vese, Donato

Year: 2020

description: Il presente articolo analizza le misure amministrative e, più nello specifico, la strategia amministrativa adottata nell’immediatezza dell’emergenza dal governo italiano al fine di determinare se tale strategia sia stata efficace nel gestire la pandemia COVID-19 su tutto il territorio nazionale. Nell’analizzare ciò, l’articolo sottolinea il ruolo svolto dall’attuale sistema di separazione dei poteri costituzionali nella gestione delle emergenze e come questo sistema possa influire sulla valutazione del rischio sanitario. Viene fornita una spiegazione del sistema di gestione del rischio nella legislazione italiana e dell’Unione Europea (UE) e vengono affrontati i seguenti nodi legali: (i) la nozione e le caratteristiche della regolazione dell’emergenza da una prospettiva pandemica, distinguendo tra rischio ed emergenza; (ii) il potenziale e i limiti del principio di precauzione nel diritto dell’UE; (iii) lo scenario costituzionale italiano rispetto alle principali disposizioni che regolano i poteri del governo centrale, regionale e degli enti locali. Nello specifico, questo articolo sostiene che la strategia amministrativa per attuare efficacemente la regolazione dei rischi di emergenza basata su un’adeguata e corretta valutazione del rischio richiede la “condivisione dei poteri” nei diversi livelli di governo con la partecipazione di tutti gli attori istituzionali coinvolti nel processo decisionale: governo, regioni ed enti locali.

description: Conical intersections constitute the conceptual bedrock of our working understanding of ultrafast, nonadiabatic processes within photochemistry (and photophysics). Accurate calculation of potential energy surfaces within the vicinity of conical intersections, however, still poses a serious challenge to many popular electronic structure methods. Multiple works have reported on the deficiency of methods like linear-response time-dependent density functional theory within the adiabatic approximation (AA LR-TDDFT) or algebraic diagrammatic construction to second-order (ADC(2)) - approaches often used in excited-state molecular dynamics simulations - to describe conical intersections between the ground and excited electronic states. In the present study, we focus our attention on conical intersections between excited electronic states and probe the ability of AA LR-TDDFT and ADC(2) to describe their topology and topography, using protonated formaldimine and pyrazine as two exemplar molecules. We also take the opportunity to revisit the performance of these methods in describing conical intersections involving the ground electronic state in protonated formaldimine - highlighting in particular how the intersection ring exhibited by AA LR-TDDFT can be perceived either as a (near-to-linear) seam of intersection or two interpenetrating cones, depending on the magnitude of molecular distortions within the branching space.

description: We introduce various optimization schemes for highly accurate calculation of the eigenvalues and the eigenfunctions of the one-dimensional anharmonic oscillators. We present several methods of analytically fixing the nonlinear variational parameter specified by the domain of the trigonometric basis functions. We show that the optimized parameter enables us to determine the energy spectrum to an arbitrary accuracy. Also, using the harmonic oscillator basis functions, we indicate that the resulting optimal frequency agrees with the one obtained by the principle of the minimal sensitivity.

description: We introduce the submissions of the NJUNLP team to the WMT 2023 Quality Estimation (QE) shared task. Our team submitted predictions for the English-German language pair on all two sub-tasks: (i) sentence- and word-level quality prediction; and (ii) fine-grained error span detection. This year, we further explore pseudo data methods for QE based on NJUQE framework (https://github.com/NJUNLP/njuqe). We generate pseudo MQM data using parallel data from the WMT translation task. We pre-train the XLMR large model on pseudo QE data, then fine-tune it on real QE data. At both stages, we jointly learn sentence-level scores and word-level tags. Empirically, we conduct experiments to find the key hyper-parameters that improve the performance. Technically, we propose a simple method that covert the word-level outputs to fine-grained error span results. Overall, our models achieved the best results in English-German for both word-level and fine-grained error span detection sub-tasks by a considerable margin.

Provenance in relational databases : usability and applications
Creators: name: AlOmeir, Omar
Publisher: name: University of British Columbia
Year: 2023

description: Data provenance is any information about the origin of a piece of data and the process that led to its creation. Most database provenance work has focused on creating models and semantics to query and generate this provenance information. While comprehensive, provenance information remains large and overwhelming, which can make it hard for data provenance systems to support data exploration or any meaningful applications. This thesis is focused on facilitating the use of database provenance through visual interfaces, summarization techniques, and curation techniques for real world applications. In the first part, we present visualization techniques for provenance information in relational databases. Our visualizations address every part of provenance information to facilitate user exploration. Through a user experiment, we show that our approach improves the accuracy and efficiency of performing exploration tasks. The next part addresses the challenge of volume of provenance information. Specifically, in the case of aggregation queries. The volume increases with the size of the database and creates a "needle in a haystack problem". We present novel summarization techniques that build on existing summarization literature. Our techniques work to support exploration for users who are not familiar with the data or its provenance. The final part shows our use of our summarization techniques to address the problem of refining aggregate queries. Aggregate queries pose a challenge in that they present ambiguous results to inexperienced users. Query refinement can help users realize their query errors and help them fix them. Through user experiment, we present evidence of the usefulness, and usability of our methods. Overall, the goal of this thesis is to facilitate the use of provenance information in relational databases. Through the use of novel techniques and user-centric evaluation, we present novel solutions and user interaction methods to enable new applications in this domain.

description: Bernstein inequalities and inverse theorems are a recent development in the theory of radial basis function(RBF) approximation. The purpose of this paper is to extend what is known by deriving $L^p$ Bernstein inequalities for RBF networks on $\mathbb{R}^d$. These inequalities involve bounding a Bessel-potential norm of an RBF network by its corresponding $L^p$ norm in terms of the separation radius associated with the network. The Bernstein inequalities will then be used to prove the corresponding inverse theorems.

description: Coulomb interactions among electrons and holes in two-dimensional (2D) semimetals with overlapping valence and conduction bands can give rise to a correlated insulating ground state via exciton formation and condensation. One candidate material in which such excitonic state uniquely combines with non-trivial band topology are atomic monolayers of tungsten ditelluride (WTe2), in which a 2D topological excitonic insulator (2D TEI) forms. However, the detailed mechanism of the 2D bulk gap formation in WTe2, in particular with regard to the role of Coulomb interactions, has remained a subject of ongoing debate. Here, we show that WTe2 is susceptible to a gate-tunable quantum phase transition, evident from an abrupt collapse of its 2D bulk energy gap upon ambipolar field-effect doping. Such gate tunability of a 2D TEI, into either n- and p-type semimetals, promises novel handles of control over non-trivial 2D superconductivity with excitonic pairing.

How Academic Streaming is failing Black Students in Ontario Schools
Creators: Duale, Amal
Publisher: name: University of Alberta Library
Year: 2025

This capstone paper explores academic streaming and how it has historically affected Black students within Ontario secondary schools. This type of streaming occurs when students’ choose a stream or pathway in grade 9, opting for academic, applied or workplace focused courses. The course choices of students at this level have great significance to their academic careers in secondary school and beyond. Historically, Black students in Ontario schools have consistently been overrepresented in lower-level streams (Livingstone, 2017; James & Turner, 2017). This topic will be explored using the Critical Anti-Racist Theory framework (CART) which will center race as the standpoint from which to discuss this issue (Dei & Lordon, 2013). This framework will take into consideration racism, history, power relations and various systems of oppression which will provide a holistic view into the intersecting factors that affect the stream choice and ultimately academic success of Black students in Ontario secondary schools (Dei & Lordon, 2013).

description: We report the synthesis, characterization, low-temperature magnetic, and thermodynamic measurements of the novel milli-Kelvin adiabatic demagnetization refrigeration (mK-ADR) candidate material NaYbGeO$_4$ which exhibits a distorted square lattice arrangement of YbO$_{6}$ magnetic units. Magnetization and specific heat indicate weakly interacting effective spin-1/2 moments below 10~K, with a Curie-Weiss temperature of only 15~mK, that can be polarized by magnetic fields of order 1~T. For the ADR performance test, we start the demagnetization from 5~T at a temperature of $\sim 2$~K and reach a minimum temperature of 150~mK at zero field. The warming curve indicates a sharp magnetic transition in the heat capacity at 210~mK, implying only weak magnetic frustration. The entropy density of $S_{\rm GS}\simeq 101$ mJ K$ ^{-1}$cm$^{-3}$ and hold time below 2~K of 220~min are competitive while the minimal temperature is higher compared to frustrated Ytterbium-oxide ADR materials studied under similar conditions.

L’obiettivo è allargare lo sguardo esponendo alcune delle ragioni che spingono a ritenere auspicabile tornare a domandarsi, con riferimento alla stagione che si sta aprendo, quale sia il posto del diritto pubblico e dell’amministrazione e, dunque, quali ruolo siano chiamati a svolgere nel più ampio quadro della governance eurounitaria. Sebbene all’apparenza quella indicata possa sembrare una mera questione teorica, di scarso interesse pratico, la risposta a tali interrogativi riveste in realtà un’importanza centrale per delineare presupposti e limiti dell’auspicato intervento pubblico nell’economia e, dunque, per garantire il migliore utilizzo possibile delle risorse del Recovery Fund in relazione agli interessi in gioco.

Il costituzionalismo contemporaneo ai tempi del Covid-19
Creators: name: Schiavello, Aldo
Publisher: name: P.A. Persona e Amministrazione
Year: 2020

description: L’indeterminatezza è una delle caratteristiche salienti del diritto negli stati costituzionali contemporanei. Tale caratteristica mette in crisi le concezioni “oggettualistiche” del diritto che riducono il diritto a un insieme di norme o a un insieme di fatti e corrobora quelle concezioni che considerano il diritto una pratica sociale interpretativa. La costituzionalizzazione degli ordinamenti giuridici accresce la flessibilità del diritto a detrimento della certezza e impone a tutti – legislatori, giudici e individui soggetti al diritto – di assumersi le proprie responsabilità e i rischi che ne conseguono. Il modo in cui il legislatore, a diversi livelli, fronteggia l’attuale pandemia da Covid-19 costituisce un interessante angolo visuale per riflettere sugli effetti – alcuni positivi, altri negativi – prodotti dall’indeterminatezza del diritto contemporaneo.

description: In this paper, we aim to analyse the impact of hydrogen production decarbonisation and electrification scenarios on the infrastructure development, generation mix, $CO_{2}$ emissions, and system costs of the European power system, considering the retrofit of the natural gas infrastructure. We define a reference scenario for the European power system in 2050 and use scenario variants to obtain additional insights by breaking down the effects of different assumptions. The scenarios were analysed using the European electricity market model COMPETES, including a proposed formulation to consider retrofitting existing natural gas networks to transport hydrogen instead of methane. According to the results, 60% of the EU's hydrogen demand is electrified, and approximately 30% of the total electricity demand will be to cover that hydrogen demand. The primary source of this electricity would be non-polluting technologies. Moreover, hydrogen flexibility significantly increases variable renewable energy investment and production, and reduces $CO_{2}$ emissions. In contrast, relying on only electricity transmission increases costs and $CO_{2}$ emissions, emphasising the importance of investing in an $H_{2}$ network through retrofitting or new pipelines. In conclusion, this paper shows that electrifying hydrogen is necessary and cost-effective to achieve the EU's objective of reducing long-term emissions.

description: We present an economical setup for faithful entanglement sharing against collective noise. It is composed of polarizing beam splitters, half wave plates, polarization independent wavelength division multiplexers, and frequency shifters. An arbitrary qubit error on the polarization state of each photon in a multi-photon system caused by the noisy channel can be rejected, without resorting to additional qubits, fast polarization modulators, and nondestructive quantum nondemolition detectors. Its success probability is in principle 100%, which is independent of the noise parameters, and it can be applied directly in any one-way quantum communication protocol based on entanglement.

We also prove that if one assumes a certain compatibility condition between Adler's and Howe's construction of supercuspidal representations, then the conjectural positive depth local Langlands correspondence of Reeder also agrees with the positive depth local Langlands correspondence as described by Moy, for $GL(\ell,F)$. Specifically, we first work out in detail the construction of DeBacker/Reeder for $GL(\ell,F)$, we then restate the constructions in the language of Moy, and finally prove that the correspondences agree. Up to a compatibility between Adler's and Howe's constructions, we then do the same for Reeder's positive depth construction.

description: La risposta amministrativa alla pandemia da covid-19 ha reso manifesta l’inadeguatezza del sistema del governo locale articolato in un elevatissimo numero di comuni con dimensioni spesso molto ridotte. Sotto altro profilo, la risposta comunale alla pandemia si è caratterizzata per l’adozione di ordinanze contingibili e urgenti di dubbia compatibilità con la legalità costituzionale. Riflettendo su questi elementi, l’articolo individua rapidamente alcune possibili prospettive di riforma dell’autonomia comunale in Italia.

Emergenza, pandemia, sovranità popolare e diritti della persona. Qualche dubbio sulla lettura biopolitica
Creators: name: Tropea, Giuseppe

Year: 2020

description: Nel saggio si prendono in esame alcune criticità derivanti dall’uso della c.d. biopolitica da parte del giurista, con particolare riguardo all’analisi dell’impatto del Covid 19 sugli ordinamenti giuridici. In particolare la biopolitica, nella misura in cui implica una radicale incompatibilità con le ricostruzioni giuridiche del potere, impone un ripensamento completo anche delle più o meno recenti critiche della sovranità, e una lettura diffidente della stessa nozione di sussidiarietà c.d. orizzontale. Con riguardo a quest’ultimo aspetto si richiamano i casi del contact tracing digitale e dei c.d. assistenti civici. Questo non significa che non sia possibile tentare una rilettura biopolitica delle tendenze del diritto pubblico degli ultimi decenni, a patto però di cogliere fino in fondo le sfide metodologiche lanciate al giurista da quella linea filosofica, generalmente trascurata dagli studiosi italiani del diritto pubblico.

description: Whether or not perfect imaging is obtained in the mirrored version of Maxwell's fisheye lens is debated in the comment/reply sequence [Blaikie-2010njp, Leonhardt-2010njp] discussing Leonhardt's original paper [Leonhardt-2009njp]. Here we show that causal solutions can be obtained without the need for an "active localized drain", contrary to the claims in [Leonhardt-2010njp].

description: Let $R$ be a 2-dimensional normal excellent henselian local domain in which 2 is invertible and let $L$ and $k$ be respectively its fraction field and residue field. Let $Ω_R$ be the set of rank 1 discrete valuations of $L$ corresponding to codimension 1 points of regular proper models of $\Spec R$. We prove that a quadratic form $q$ over $L$ satisfies the local-global principle with respect to $Ω_R$ in the following two cases: (1) $q$ has rank 3 or 4; (2) $q$ has rank $\ge 5$ and $R=A[y]$, where $A$ is a complete discrete valuation ring with a not too restrictive condition on the residue field $k$, which is satisfied when $k$ is $C_1$.

Emergenza e organizzazione

description: Il contributo offre una riflessione ad ampio spettro sugli effetti dell’emergenza pandemica sull’ordinamento costituzionale. Si evidenzia anzitutto come i concetti di necessità ed urgenza, o più semplicemente di “crisi”, legittimino da sempre l’attribuzione di poteri eccezionali di adozione di determinate decisioni, molto spesso in deroga ai normali meccanismi di funzionamento degli organi collegiali a favore di decisioni monocratiche. Sul piano ordinamentale possono osservarsi due tendenze dovute alle situazioni di crisi: la migrazione delle competenze dal legislativo all’esecutivo, e dalla periferia al centro; tale dinamica collide con l’assetto istituzionale pluralistico del nostro ordinamento costituzionale generando una sovrapposizione di funzioni, a sua volta aggravata dalle distanze politiche tra i vari livelli di governo. L’altra rilevante conseguenza delle misure emergenziali è la compressione dei diritti fondamentali di rango costituzionale, il cui godimento dovrebbe essere oggetto di bilanciamento con altre esigenze collettive (in primis, la salute pubblica) nel rigoroso rispetto del nucleo essenziale di tali diritti. L’emergenza fa vacillare anche il rigoso rispetto del principio di riserva di legge: da un lato, con la delegificazione anomala tramite D.P.C.M.; dall’altro lato, con l’inserimento nelle leggi di conversione dei decreti legge di disposizioni non giustificate dall’emergenza, derogando così all’ordinario procedimento legislativo.

Emergenza e decisioni di finanza pubblica: prima e dopo il Covid-19

description: Si è evidenziato in più sedi come la pandemia da Covid-19 e la conseguente risposta da parte delle istituzioni non abbiano fatto altro che enfatizzare alcune tendenze di fondo già presenti nel sistema. Il fenomeno è particolarmente evidente nel settore della contabilità pubblica, in cui la necessità di apprestare soluzioni immediate a supporto sia del sistema sanitario che dell’economia nel suo complesso hanno messo luce la netta tendenza ad una marginalizzazione delle assemblee rappresentative nelle decisioni sull’allocazione delle risorse. Il presente studio si propone allora di analizzare come le dinamiche verificatesi recentemente in fase di adozione dei vari documenti che compongono la manovra finanziaria ma più in generale delle decisioni di spesa in senso lato (incluse quelle sviluppatesi nel corso dello stato di emergenza di cui alla D.C.M. 31 luglio 2020) rappresentino probabilmente il sintomo più evidente di un profondo cambio di assetto della forma di governo, in cui – all’irrigidirsi della normativa europea e costituzionale in materia di bilancio e al correlato sviluppo di un dialogo procedimentalizzato con le istituzioni di Bruxelles – si è accompagnata una progressiva marginalizzazione delle assemblee parlamentari. Se dunque il bilancio (ma più in generale ogni provvedimento di spesa) – per utilizzare la nota formulazione Buscema – non è altro che la «trascrizione in termini contabili» dell’indirizzo politico – la crisi del parlamentarismo diviene specchio di una più estesa crisi della democrazia rappresentativa, sicché la predisposizione di nuovi meccanismi di riequilibrio nei rapporti tra esecutivo e legislativo diviene centrale nel salvaguardare il nucleo-forte della rappresentanza politica, per cui il Parlamento non può essere chiamato ad una mera ratifica in extremis di decisioni assunte da altri.

description: We show that a class of divergence-form elliptic problems with quadratic growth in the gradient and non-coercive zero order terms are solvable, under essentially optimal hypotheses on the coefficients in the equation. In addition, we prove that the solutions are in general not unique. The case where the zero order term has the opposite sign was already intensively studied and the uniqueness is the rule.

Brain injury and brain health among individuals living in homelessness or precarious housing

description: Individuals living in homelessness or precarious housing experience poorer health and earlier mortality than the general population. The overall objective of this work was to characterize the role of traumatic brain injury in the health of these individuals, and evaluate quantitative structural magnetic resonance imaging (MRI) measures of brain structure among these individuals. First, we conducted a systematic review and meta-analysis on the prevalence, incidence, and role of traumatic brain injury in the health of these individuals. We found that more than half of individuals living in homelessness or precarious housing had experienced a traumatic brain injury during their lifetime, while more than one in five had experienced a moderate or severe traumatic brain injury. History of traumatic brain injury was associated with poorer mental and physical health, and poorer functioning. Next, we evaluated quantitative MRI measures of brain macrostructure and microstructure among these individuals compared to a general population sample. Using data from a large study of individuals living in homelessness or precarious housing (n=312), we found that older age was associated with more whole-brain atrophy and decrements in white matter measures as compared to the general population sample (n=382). History of traumatic brain injury, stimulant dependence, and heroin dependence were associated with further decrements in these MRI measures. Finally, we evaluated longitudinal trajectories of these MRI measures among individuals living in homelessness or precarious housing (n=300) and how these trajectories were associated with health and functioning. Rates of change varied across regions of interest, and traumatic brain injury, cardiovascular risk scores, alcohol dependence, and opioid dependence were associated with further decrements in these MRI measures. More rapid decline in MRI measures was associated with declining physical health, declining cognitive functioning, and mortality. Overall, we found that traumatic brain injury is more prevalent among individuals living in homelessness or precarious housing than in the general population, and that traumatic brain injury and other risk factors are associated with decrements in MRI measures of brain structure. A concerted effort is needed to ameliorate the brain health disparities experienced by individuals living in homelessness or precarious housing.

description: Let $E$ be a finite dimensional vector space over a local field, and $F$ be its dual. For a closed subset $X$ of $E$, and $Y$ of $F$, consider the space $D^{-ξ}(E;X,Y)$ of tempered distributions on $E$ whose support are contained in $X$ and support of whose Fourier transform are contained in $Y$. We show that $D^{-ξ}(E;X,Y)$ possesses a certain rigidity property, for $X$, $Y$ which are some finite unions of affine subspaces.

description: Wavefront shaping is a technique to study and control light transport inside scattering media. Wavefront shaping is considered to be applicable to any complex material, yet in most previous studies, the only sample geometries that are studied are slabs or wave-guides. In this paper, we study how macroscopic changes in the sample shape affect light scattering using the wavefront shaping technique. Using a flexible scattering material, we optimize the intensity of light in a focusing spot using wavefront shaping and record the optimized pattern, comparing the enhancement for different curvatures and beam radii. We validate our hypothesis that wavefront shaping has a similar enhancement regardless of the free-form shape of the sample and thus offers relevant potential for industrial applications. We propose a new figure of merit to evaluate the performance of wavefront shaping for different shapes. Surprisingly, based on this figure of merit, we observe that for this particular sample, wavefront shaping has a slightly better performance for a free-form shape than for a slab shape.

description: Il Progetto Quadro e gli Accordi esecutivi firmati nel corso del 2019, per istituire la figura dell’Infermiere di Parrocchia, rappresentano una novità nel quadro di collaborazione tra istituti religiosi e civili. In particolare i livelli di rappresentanza che emergono per le parti firmatarie e le linee applicative, la parrocchia come spazio territoriale e non come comunità di fedeli, rendono di difficile collocazione queste accordi tra le fonti giuridiche e si inseriscono in un nuovo filone di regolamentazione bilaterale dei servizi ai cittadini.
