description: We report on the vapor-solid growth of single crystalline few-layer MoS2 films on (0001)-oriented sapphire with excellent structural and electrical properties over centimeter length scale. High-resolution X-ray diffraction scans indicated that the films had good out-of-plane ordering and epitaxial registry. A carrier density of ~2 x 1011 cm-2 and a room temperature mobility of 192 cm2/Vs were extracted from space-charge limited transport regime in the films. The electron mobility was found to exhibit in-plane anisotropy with a ratio of ~ 1.8. Theoretical estimates of the temperature-dependent electron mobility including optical phonon, acoustic deformation potential and remote ionized impurity scattering were found to satisfactorily match the measured data. The synthesis approach reported here demonstrates the feasibility of device quality few-layer MoS2 films with excellent uniformity and high quality.

description: In a recent contribution, Bahl \& Baumgardt investigated the incidence of planar alignments of satellite galaxies in the Millennium-II simulation, and concluded that vast thin planes of dwarf galaxies, similar to that observed in the Andromeda galaxy (M31), occur frequently by chance in $Λ$-Cold Dark Matter cosmology. However, their analysis did not capture the essential fact that the observed alignment is simultaneously radially extended, yet thin, and kinematically unusual. With the caveat that the Millennium-II simulation may not have sufficient mass resolution to identify confidently simulacra of low-luminosity dwarf galaxies, we re-examine that simulation for planar structures, using the same method as employed by Ibata et al. (2013) on the real M31 satellites. We find that 0.04\% of host galaxies display satellite alignments that are at least as extreme as the observations, when we consider their extent, thickness and number of members rotating in the same sense. We further investigate the angular momentum properties of the co-planar satellites, and find that the median of the specific angular momentum derived from the line of sight velocities in the real M31 structure ($1.3\times10^4$ km/s kpc) is very high compared to systems drawn from the simulations. This analysis confirms that it is highly unlikely that the observed structure around the Andromeda galaxy is due to a chance occurrence. Interestingly, the few extreme systems that are similar to M31 arise from the accretion of a massive sub-halo with its own spatially-concentrated entourage of orphan satellites.

description: Optical fibers have found widespread use in engineering, from communication to sensors. Among them, Fiber Bragg Gratings are allowed to detect several parameters. Scope of this work is to assess their performances as temperature and mechanical strain sensors for aerospace: in this regard, an experimental calibration is discussed. Then, alternative approaches are tested in order to distinguish thermal from mechanical contributes. This is first addressed by using a hybrid system of digital and optical sensors, and then then with a fully optical system. Both the presented solutions reached the scope. A concept of a third, innovative approach, is also described.

The interdot coupling can be tuned over a wide range, from formation of a large single dot to two well-isolated quantum dots. Using charge sensing, we show the ability to completely empty the dot of holes and control the charge occupation in the few-hole regime. The device should allow for control of individual hole spins in single and double quantum dots in GaAs.

description: COMPASS is a fixed-target experiment at the CERN SPS which focused on light-quark hadron spectroscopy during the data taking periods in 2008 and 2009. A world-leading data set was collected with a 190GeV/c hadron beam impinging on a liquid hydrogen target in order to study, inter alia, the central exclusive production of glueball candidates in the light-meson sector. Especially the double-Pomeron exchange mechanism is well suited for the production of mesons without valence quark content. We select centrally produced systems with two pseudo-scalar mesons in the final state from the COMPASS data set recorded with an incoming proton. The decay of this system is decomposed in terms of partial waves, where particular attention is paid to the inherent mathematical ambiguities of the amplitude analysis. Furthermore, we show that simple parametrisations are able to describe the mass dependence of the fit results with sensible Breit-Wigner parameters.

DETAILED CHEMISTRY SCHEMES

description: The increasing interest in reusable LOx/CH4 first-stage liquid rocket engines requires the further development of suitable computational fluid dynamics tools for the reliable design and analysis of such engines. Shifting from classical LOx/H2 to methane as a fuel involves many challenges for the accurate modeling of chemical effects as the characteristic time scale for LOx/CH4 is significantly longer than for hydrogen. This may result in, for example, flame lift-off and reattachment effects that may cause substantial combustion instabilities. Also, the injector wall temperature may play a more significant role than in classical LOx/H2 engines. The purpose of this study is to compare numerical simulation results using a complex detailed-chemistry scheme with previous results obtained with a real-gas flamelet combustion model. Additionally, a novel machine-learning based approach for the efficient tabulation of chemical reactions rates will be tested and compared against results with the full reaction mechanism. This comparison will be based on two dedicated numerical test cases which have been used extensively in the past: The first one is a modified version of the 2D mixing test case proposed in Ruiz et al.17 This computationally cheap setup allows for a detailed study of mixing and chemical reactions under thermodynamic conditions that are representative for rocket engine. A more realistic setup will be investigated with the second test case HF-10 from the Franco-German Rocket Engine Stability Initiative (REST). In this test case, the flame behind a realistic single shear-coaxial injector will investigated in a 3D simulation at supercritical condi4tions. This paper continues our work on the HF-10 test case , 19 presented at the EU CASS 2022 conference and allows for a more general assessment of chemical non-equilibrium effects at supercritical pressures commonly encountered in liquid rocket engines.

description: We present 4.5 μm luminosity functions for galaxies identified in 178 candidate galaxy clusters at 1.3 < z < 3.2. The clusters were identified as Spitzer/IRAC color-selected overdensities in the Clusters Around Radio-Loud AGN (CARLA) project, which imaged 421 powerful radio-loud AGN at z > 1.3. The luminosity functions are derived for different redshift and richness bins, and the IRAC imaging reaches depths of m*+2, allowing us to measure the faint end slopes of the luminosity functions. We find that α = -1 describes the luminosity function very well in all redshifts bins and does not evolve significantly. This provides evidence that the rate at which the low mass galaxy population grows through star formation, gets quenched and is replenished by in-falling field galaxies does not have a major net effect on the shape of the luminosity function. Our measurements for m* are consistent with passive evolution models and high formation redshifts z_f ~ 3. We find a slight trend towards fainter m* for the richest clusters, implying that the most massive clusters in our sample could contain older stellar populations, yet another example of cosmic downsizing. Modelling shows that a contribution of a star-forming population of up to 40% cannot be ruled out. This value, found from our targeted survey, is significantly lower than the values found for slightly lower redshift, z ~ 1, clusters found in wide-field surveys. The results are consistent with cosmic downsizing, as the clusters studied here were all found in the vicinity of radio-loud AGNs -- which have proven to be preferentially located in massive dark matter halos in the richest environments at high redshift -- they may therefore be older and more evolved systems than the general protocluster population.

description: We perform an exploratory study of the physical properties of accretion flows and jets in low-luminosity active galactic nuclei (LLAGNs) by modeling the spectral energy distributions (SEDs) of 12 LLAGNs in low-ionization nuclear emission-line regions (LINERs). These SEDs we constructed from high-resolution radio, X-ray and optical/UV observations of the immediate vicinity of the black hole. We adopt a coupled accretion-jet model comprising an inner advection-dominated accretion flow (ADAF) and an outer standard thin disk. We present best-fit models in which either the ADAF or the jet dominate the X-ray emission. Six sources in our sample display an optical-UV excess with respect to ADAF and jet models; this excess can be explained as emission from the truncated disk with transition radii 30-225 Rs in four of them. In almost all sources the optical emission can also be attributed to unresolved, old stellar clusters with masses ~1E7-1E8 Msun. We find evidence for a correlation between the accretion rate and jet power and an anti-correlation between the radio-loudness and the accretion rate. We confirm previous findings that the radio emission is severely underpredicted by ADAF models and explained by the relativistic jet. We find evidence for a nonlinear relation between the X-ray and bolometric luminosities and a slight IR excess in the average model SED compared to that of quasars. We suggest that the hardness of the X-ray spectrum can be used to identify the X-ray emission mechanism and discuss directions for progress in understanding the origin of the X-rays.

description: The condition of thermal equilibrium simplifies the theoretical treatment of fluctuations as found in the celebrated Einstein's relation between mobility and diffusivity for Brownian motion. Several recent theories relax the hypothesis of thermal equilibrium resulting in at least two main scenarios. With well separated timescales, as in aging glassy systems, equilibrium Fluctuation-Dissipation Theorem applies at each scale with its own "effective" temperature. With mixed timescales, as for example in active or granular fluids or in turbulence, temperature is no more well-defined, the dynamical nature of fluctuations fully emerges and a Generalized Fluctuation-Dissipation Theorem (GFDT) applies. Here, we study experimentally the mixed timescale regime by studying fluctuations and linear response in the Brownian motion of a rotating intruder immersed in a vibro-fluidized granular medium. Increasing the packing fraction, the system is moved from a dilute single-timescale regime toward a denser multiple-timescale stage. Einstein's relation holds in the former and is violated in the latter. The violation cannot be explained in terms of effective temperatures, while the GFDT is able to impute it to the emergence of a strong coupling between the intruder and the surrounding fluid. Direct experimental measurements confirm the development of spatial correlations in the system when the density is increased.

description: Ton-scale liquid xenon detectors operated in two-phase mode are proposed and being constructed recently to explore the favored parameter space for the Weakly Interacting Massive Particles (WIMPs) dark matter. To achieve a better light collection eff ciency while limiting the number of electronics channels compared to the previous generation detectors, large-size photomultiplier tubes (PMTs) such as the 3-inch-diameter R11410 from Hamamatsu are suggested to replace the 1-inch-square R8520 PMTs. In a two-phase xenon dark matter detector, two PMT arrays on the top and bottom are usually used. In this study, we compare the performance of two different ton-scale liquid xenon detector conf gurations with the same number of either R11410 (conf g.1) or R8520 (conf g.2) for the top PMT array, while both using R11410 PMTs for the bottom array.

description: We describe and evaluate the semi-automatic addition of a deep syntactic layer to the French Treebank (Abeillé and Barrier [1]), using an existing scheme (Candito et al. [6]). While some rare or highly ambiguous deep phenomena are handled manually, the remainings are derived using a graph-rewriting system (Ribeyre et al. [22]). Although not manually corrected, we think the resulting Deep Representations can pave the way for the emergence of deep syntactic parsers for French.

description: We consider quantum chromodynamics (QCD) with Nc colors and Nf quark flavors at finite quark chemical potential mu_q or isospin chemical potential mu_I. We specifically address the nature of the ``Silver Blaze'' behavior in the framework of 1/Nc expansion. Starting with the QCD partition function, we implement Veneziano's Nf/Nc expansion to identify the density onset. We find the baryon mass M_B and the pion mass m_pi appearing from different order of Veneziano's expansion. We argue that the confining properties are responsible for the Silver Blaze in the region of m_pi/2 < mu_q < M_B/Nc. We point out, however, that Veneziano's expansion brings about a puzzling subtlety along the same line as the baryon problem in finite-density quenched simulations. We emphasize that the large-Nc limit can allow for the physical ordering of M_B and m_pi thanks to the similarity to the quenched approximation, while the unphysical ghost quarks contaminate the baryon sector if Nc is finite. We also discuss the ``orientifold'' large-Nc limit that does not quench quark loops.

description: In this contribution, large eddies simulations is carried out to shed light on the injector near-field and heat transfer in a reference methane-oxygen rocket combustion chamber. This is performed by parametrically varying the confinement length of the injector from the baseline value up to twice that distance. Preliminary results indicate that, as expected, as the confinement length is increasing, larger and warmer recirculating flow pattern are visible and higher values of the wall heat flux on the injector faceplate are obtained. Such results are finally compared with literature unsteady RANS data showing compatible trends.

description: In this contribution, a tabulated vapor-liquid-equilibrium thermodynamic framework is proposed to assess phase separation phenomena for liquid-oxygen gaseous-hydrogen propellant combination under conditions relevant for rockets. The model is validated and integrated into a computational fluid dynamics solver capable of handling large density gradients. Employing a zero-dimensional thermodynamic analysis, the encountered peculiar vapor-liquid-equilibrium conditions and their impact on the fluid properties are quantified. Finally, the framework is employed to investigate a reference two-dimensional supercritical mixing layer and the main differences induced by the two-phase flow effect are discussed.

description: We consider the effects of non-universalities among sfermion generations in models of Pure Gravity Mediation (PGM). In PGM models and in many models with strongly stabilized moduli, the gravitino mass may be O(100) TeV, whereas gaugino masses, generated through anomalies at 1-loop, remain relatively light O(1) TeV. In models with scalar mass universality, input scalar masses are generally very heavy (m_0 \simeq m_{3/2}) resulting in a mass spectrum resembling that in split supersymmetry. However, if one adopts a no-scale or partial no-scale structure for the Kähler manifold, sfermion masses may vanish at the tree level. It is usually assumed that the leading order anomaly mediated contribution to scalar masses appears at 2-loops. However, there are at least two possible sources for 1-loop scalar masses. These may arise if Pauli-Villars fields are introduced as messengers of supersymmetry breaking. We consider the consequences of a spectrum in which the scalar masses associated with the third generation are heavy (order m_{3/2}) with 1-loop scalar masses for the first two generations. A similar spectrum is expected to arise in GUT models based on E_7/SO(10) where the first two generations of scalars act as pseudo-Nambu-Goldstone bosons. Explicit breaking of this symmetry by the gauge couplings then generates one-loop masses for the first two generations. In particular, we show that it may be possible to reconcile the g_mu - 2 discrepancy with potentially observable scalars and gauginos at the LHC.

description: A multi-injector combustion chamber simulation is developed to investigate the injection region in an inherently three-dimensional setting by means of unsteady RANS simulations. Results have been compared to a database of two-dimensional simulations previously collected and used as a stepping stone for the preliminary development and validation of a data-driven model for the characterization of complex geometries in an early design phase. Finally, the injector density has been varied to assess its effect on the flow field and thermal load. It has been observed that a less dense configuration corresponds to wider and warmer recirculations, leading to higher thermal loads.

The developed VPP quickly reacts to changing requirements (legal, economic, technical) without harming the stability of the system.
Querying topological fields in the TIGER scheme with TIGERSearch
Creators: name: Dipper, Stefanie
Publisher: name: University of Tübingen
Year: 2014

description: The TIGER corpus is a German treebank with a hybrid dependency-constituency annotation. In this paper, I address the question how well topological fields (e.g. Vorfeld, Verb second) can be searched in this treebank, using the search tool TIGERSearch. For most queries, a version without crossing branches is used. It turns out that queries can be formulated that result in quite good F-scores for the Vorfeld and left and right brackets. Mittelfeld and Nachfeld are hard to query. This is due partly to properties of the language, partly to design decisions in the TIGER scheme, and partly to restrictions imposed by the search tool.

We numerically solve the time dependent Bogoliubov-de Gennes equations and characterize the regimes of Josephson oscillations and self-trapping for different potential barriers and initial conditions. In the weak link limit the results agree with a two-mode model where the relative population and the phase difference between the two wells obey coupled nonlinear Josephson equations. A more complex dynamics is predicted for large amplitude oscillations and large tunneling.

title: Not Every Man was Male: Gender Passing in Nineteenth Century Britain
Creators: name: Thomason, B-G
Publisher: name: Liverpool John Moores University
Year: 2020

description: Not Every Man was Male: Gender Passing in Nineteenth Century Britain uses the nineteenth-century press to create microbiographies about the lives of twenty-five working-class female to male gender passing individuals. These microbiographies have been developed using newspapers, census material, and trade directories. By using a combination of microhistory (Carlo Ginzburg and Levi Magnusson) and record linkage this thesis recovers the life stories of gender passing individuals who have, until now, largely remained obscured in history. This thesis demonstrates how individuals attempted to live their lives in a way that was not bound to their biological identity. It also highlights how nineteenth-century society understood gender passing individuals and marked their ability to practice their masculinity in a recognisable manner. At the core of this thesis is the assertion that gender was performative, malleable, and unstable. Consequently, this thesis builds on Judith Butler’s idea of gender being a ‘free-floating artifice’ and like Don Zimmerman and Candace West, recognises that gender is something to be ‘done’. To fully examine these assertions, I have developed new terminology and a conceptual framework to understand ‘gender passing individuals’ in a historical context. The concept of ‘gender passing’ has been coined by me and builds on the work of Elaine Ginsberg and Irving Goffman, who both argue that ‘passing’ is used to understand how people moved beyond race, class and gender. Gender passing individuals performed aspects of nineteenth-century masculinity in a way that was recognisable by others. Similarly, this thesis develops the ‘4 C’s of Passing’ framework to consider how gender passing individuals were confident, consistent, and committed to their gender performativity and reflects on how they concealed their biological bodies.
title: A STUDY INTO THE VALUE PLACED ON NUMERACY AS SYMBOLIC CAPITAL WITHIN THE JOURNALISTIC FIELD
Creators: name: Harrison, S
Publisher: name: Liverpool John Moores University
Year: 2020

description: Journalists need a clear understanding of numbers and to be comfortable communicating them if they are to perform their role of informing the public and holding power to account. That is because numbers are at the heart of almost every topic of public interest: from health, wellbeing and politics to sport, the economy and business. Yet the popular image of the journalist is that of a barely-numerate wordsmith, at home with prose but bewildered by percentages. If true, that is damaging to public discourse, both in terms of what is and is not reported, and how effectively it is communicated. This research project proceeds from the observation that journalists have a “numeracy deficit” when it comes to writing with and about numbers, and it analyses this deficit in an original manner by drawing on Bourdieu’s concepts of the journalistic field, symbolic capital and habitus, employing these as the basis for a fresh understanding of the topic. By comparing journalism students with statistics students, the role of habitus and cultural capital is invoked to theorise how the development of journalism students’ numeracy skills is inhibited. A numeracy audit of UK newspapers illustrates common errors when reporting on stories which involve quantitative data, and it is argued these arise in large part because numeracy is not valued within the journalistic field to the extent that literacy is. Case studies were critically analysed to explore the practical consequences of an inadequate level of numeracy on the quality of journalism. The findings have been supplemented by interviews with authoritative figures within the profession. By placing this topic for the first time within the context of field theory, it is argued that a solution to journalism’s numeracy deficit does not lie in training alone, as traditionally argued, but requires a transformation of the journalistic field itself.

FRONT-LOADING
AIRCRAFT DESIGN
KBE

description: The DEF AINE project proposes companies to adopt a front-loaded development process. Front-loading significantly reduces the inefficiencies of the current engineering approach by enabling large-scale design exploration early on or even before the start of a project. To this purpose, the DEFAINE framework enables fast generation of distributed, re-configurable multidisciplinary engineering workflows, built on sets of design automation solutions, largely based on Knowledge Based Engineering. The workflows are fed with varying sets of parameters and requirements, to automatically perform multiple design exploration studies. With the help of AI techniques, the produced design solutions are analyzed to derive new knowledge.

description: The effects of shock impingement and interference on local aerodynamic heating have been and still are a key issue for the design of hypersonic flight vehicles[]]. At this time DLR is involved in continuous series of sounding rocket flight experiments studying hot structures. One of these experiment is the STORT flight experiments[2]. One essential flown experiment is the fins experiment on the third stage. The fins were investigated both on the vehicle, in windtunnels in Cologne and Gi:ittingen but also numerically. For the windtunnel experiment in the HEG (High Enthalpy Shock Tunnel Gi:ittingen) the object of investigation is a plate mounted fin which scales 1 :2 to the flight hardware. The fin induced shock boundary layer interaction (SELi) on the plate leads to increased thermal loads with strong thermal gradients. The heat flux on the flat plate determined by using temperature sensitive paints (TSP[3]). In a previous study first experimental and numerical results for a sharp fin on a flat plate for two freestream HEG conditions at Mach 7.4 were presented [ 4 ]. CFD calculations at both O deg AoF and 15 deg AoF were performed and compared for flow topology and turbulence model influence. While the XIII condition compared well between experiment and CFD, the XV condition which showed clear signs of transitional flow exhibits rather complex physical phenomena which require further investigation, both experimentally and numerically. In the current study we extend the investigation to the other conditions/configurations studied and supplement the studies using RANS turbulence modelling by using Improved Detached eddy simulation(IDDES), as well as thermal and chemical non-equilibrium for select cases in order to gain a better understanding of the complex flow field found in the experiment.

Year: 2014

description: In this work, we summarize an in-depth quantitative and qualitative analysis of three dependency schemes for English, in order to acquire and document contrastive insights into how these schemes relate to each other. We demon- strate how a simple quantitative method can reveal salient structural properties of individual schemes, as well as uncover systematic correspondences between pairs of schemes. We use this method to estimate and compare the expressiveness of three dependency schemes and we identifiy several linguistic phenomena that have a different syntactic analysis in two of these schemes.

description: We present deep 1.1-3.1 GHz Australia Telescope Compact Array observations of the radio halo of the bullet cluster, 1E 0657-55.8. In comparison to existing images of this radio halo the detection in our images is at higher significance. The radio halo is as extended as the X-ray emission in the direction of cluster merger but is significantly less extended than the X-ray emission in the perpendicular direction. At low significance we detect a faint second peak in the radio halo close to the X-ray centroid of the smaller sub-cluster (the bullet) suggesting that, similarly to the X-ray emission, the radio halo may consist of two components. Finally, we find that the distinctive shape of the western edge of the radio halo traces out the X-ray detected bow shock. The radio halo morphology and the lack of strong point-to-point correlations between radio, X-ray and weak-lensing properties suggests that the radio halo is still being formed. The colocation of the X-ray shock with a distinctive radio brightness edge illustrates that the shock is influencing the structure of the radio halo. These observations support the theory that shocks and turbulence influence the formation and evolution of radio halo synchrotron emission.

description: For the proposed duality relating a family of N=4 superconformal coset models to a certain supersymmetric higher spin theory on AdS_3, the asymptotic symmetry algebra of the bulk description is determined. It is shown that, depending on the choice of the boundary charges, one may obtain either the linear or the non-linear superconformal algebra on the boundary. We compare the non-linear version of the asymptotic symmetry algebra with the non-linear coset algebra and find non-trivial agreement in the 't Hooft limit, thus giving strong support for the proposed duality. As a by-product of our analysis we also show that the W_infinity symmetry of the coset theory is broken under the exactly marginal perturbation that preserves the N=4 superconformal algebra.

Mapping Legal Framework - Preliminary Results
Creators: name: Quintais, João Pedro
Publisher: name: Zenodo
Year: 2023

description: The original aim of the Milestone was to provide for: (i) a summary of our current mapping research this far; (ii) a state of the art overview of the implementation of art. 17 CDSM Directive and EU and national level; and (iii) a discussion on potential approaches to the second part of our project (of a more evaluative nature). The event was planned to be a legal expert workshop, however, due to the COVID-19 pandemic, we had to organize the event as an online webinar, titled “The Regulatory Landscape for Copyright Content Moderation: Evaluation and Future Trajectories”. The event involved over 60 participants from all across (and beyond) Europe. This Report describes the outcomes of the Workshop.

Considerations on The Bill on “Violence or Discrimination on Grounds of Gender or Sexual Orientation” ABSTRACT: This article analyzes the legislative proposal on “violence or discrimination on grounds of gender or sexual orientation” currently under examination by the Italian Parliament. It exposes how, according to the bill, three types of behaviour would be punished under penal law: violent acts or incitements to violence, discriminatory acts, expression of discriminatory thoughts. The author shows why the new law would infringe the Italian Constitution in so far as it forbids the expression of ideas or punishes acts that have no link with violence. This would contrast with several fundamental freedoms such as the freedoms of expression, of assembly and of religion.

description: In majority dynamics, agents located at the vertices of an undirected simple graph update their binary opinions synchronously by adopting those of the majority of their neighbors. On infinite unimodular transitive graphs (e.g., Cayley graphs), when initial opinions are chosen from a distribution that is invariant with respect to the graph automorphism group, we show that the opinion of each agent almost surely either converges, or else eventually oscillates with period two; this is known to hold for finite graphs, but not for all infinite graphs. On Erdős-Rényi random graphs with degrees $Ω(\sqrt{n})$, we show that when initial opinions are chosen i.i.d. then agents all converge to the initial majority opinion, with constant probability. Conversely, on random 4-regular finite graphs, we show that with high probability different agents converge to different opinions.

description: We present switching field distributions of spin-transfer assisted magnetization reversal in perpendicularly magnetized Co/Ni multilayer spin-valve nanopillars at room temperature. Switching field measurements of the Co/Ni free layer of spin-valve nanopillars with a 50 nm x 300 nm ellipse cross section were conducted as a function of current. The validity of a model that assumes a spin-current dependent effective barrier for thermally activated reversal is tested by measuring switching field distributions under applied direct currents. We show that the switching field distributions deviate significantly from the double exponential shape predicted by the effective barrier model, beginning at applied currents as low as half of the zero field critical current. Barrier heights extracted from switching field distributions for currents below this threshold are a monotonic function of the current. However, the thermally-induced switching model breaks down for currents exceeding the critical threshold.

Strategie confessionali e prospettive interculturali: il caso delle app religiose - 4. Il download di una app tra tutela della privacy e sicurezza sociale. Internet, Cultures, Religions. Some insights for an intercultural web. ABSTRACT: The article aims to investigate the relationship between the Internet and religions. Technological evolution has produced important consequences on society and relationships between people, also involving religious denominations. The latter have defined new ways of professing and excercizing their belief: creation of Christian communities on line, Internet as window of knowledge of monastic life or proselytizing tools, propaganda through religious videogames, app for smartphones and tablets. Such tools can contribute to the formation of an intercultural web. The use of the Internet and of modern technologies questions jurists about the protection of sensitive data of religious interest and of social security. Downloading an app on smatphones and tablets allows the provider to access even the user’s sensitive data, including their religious affiliation. This requires the intervention of Italian Data Protection Authority, whose task is to check whether the processing of sensitive data is carried out in compliance with the applicable regulations. The improper use of the Internet can also involve the protection of social security, through the denigration of a particularly weak social group and as a tool of spreading and inciting hatred (hate speech). The legislator is therefore called upon to define the sanctioning capacity of the existing legal systems.
