Mass media as object of evangelization in theological perspective of apostolic exhortation Evangelii gaudium
No full textSredstvima društvenog priopćavanja autor pristupa s gledišta
evangelizacije, budući da sredstva ne samo da prenose poruku nego se po njima susreću osobe. Ta sredstva, smatra autor, premda nisu bez opasnosti po suvremenog čovjeka jer ga dovode do sve većeg otuđenja, ipak nisu kriva sama po sebi, jer je uvijek čovjek onaj koji se njima služi. Stoga je nužno i u sredstva društvenog priopćavanja uvesti evangelizaciju, a to nije drugo doli trajni poziv na obraćenje, kako Crkvi u cjelini tako i svakom pojedinom kršćaninu. Taj poziv uključuje i svijest o poslanju naviještanja Radosne vijesti i na novom području što ga stvaraju nova sredstva društvene komunikacije, tzv. “digitalnom kontinentu”. A koliko će poslanje biti uspješno ovisit će s koliko će radosti i životnog svjedočanstva kršćani biti prisutni na novom “kontinentu”.The author approaches the means of social communication from the perspective of evangelization, since they not only convey the message but through them people meet each other. The author holds that these media, though not without dangers to modern man because they lead him to ever greater alienation, are not guilty of themselves, because man is always the one who uses them. Therefore, it is necessary to introduce evangelization even in the means of social communication, which is nothing but a permanent call to conversion, both to the Church as a whole and to every single Christian. This call includes awareness of the mission of proclaiming the Good News also in the new area created by the new means of social communication, on the so called “digital continent”. The amount of success of the mission will depend on the amount of joy and life witnessing invested by the Christians on this new “continent”

The Right to Freedom of Conscience as Guarantee of Respect for Law and Freedom in Europe
No full textAutor w artykule w pierwszej kolejności opisuje genezę wolności słowa, sumienia i wyznania, a także definiuje wolność sumienia. Następnie – charakteryzując prawo do wolności sumienia w Europie wobec aktualnych wyzwań – dokonuje rozróżnienia między wolnością sumienia a prawem, jakie tę wolność chroni. Zauważa, że w Europie, w której prawnie chroniona jest wolność słowa, sumienia i wyznania, dochodzi do naruszenia prawa, zwłaszcza w stosunku do przedstawicieli religii chrześcijańskiej, w tym w szczególności względem katolików.The author at the beginning of the article describes the genesis of freedom of speech, conscience and religion, and also defines the freedom of conscience. Then – characterizing the right to freedom of conscience in Europe in the face of current challenges – he makes a distinction between the freedom of conscience and the law that protects it. He points out that in Europe in which freedom of speech, conscience and religion is legally protected, there is a violation of the law, especially towards representatives of the Christian religion, in particular against Catholics
The ALICE Software Release Validation cluster
No full textOne of the most important steps of software lifecycle is Quality Assurance: this process comprehends both automatic tests and manual reviews, and all of them must pass successfully before the software is approved for production. Some tests, such as source code static analysis, are executed on a single dedicated service: in High Energy Physics, a full simulation and reconstruction chain on a distributed computing environment, backed with a sample “golden” dataset, is also necessary for the quality sign off. The ALICE experiment uses dedicated and virtualized computing infrastructures for the Release Validation in order not to taint the production environment (i.e. CVMFS and the Grid) with non-validated software and validation jobs: the ALICE Release Validation cluster is a disposable virtual cluster appliance based on CernVM and the Virtual Analysis Facility, capable of deploying on demand, and with a single command, a dedicated virtual HTCondor cluster with an automatically scalable number of virtual workers on any cloud supporting the standard EC2 interface. Input and output data are externally stored on EOS, and a dedicated CVMFS service is used to provide the software to be validated. We will show how the Release Validation Cluster deployment and disposal are completely transparent for the Release Manager, who simply triggers the validation from the ALICE build system's web interface. CernVM 3, based entirely on CVMFS, permits to boot any snapshot of the operating system in time: we will show how this allows us to certify each ALICE software release for an exact CernVM snapshot, addressing the problem of Long Term Data Preservation by ensuring a consistent environment for software execution and data reprocessing in the future

Anisotropic flow of identified hadrons in heavy-ion collisions at the LHC: from detector alignment and calibration to measurement
No full textIn relativistic heavy-ion collisions a dense and hot medium is created. It is thought to be the quark-gluon plasma (QGP), a state of matter in which the quarks and gluons, normally confined in hadrons, are (quasi-) free. The QGP is believed to have existed in the first few microseconds after the Big Bang and is conjectured to still exist in the neutron star cores. Anisotropic flow is a measure of the momentum anisotropy of particles created in a heavy-ion collision, a consequence of the initial spatial anisotropy of the created medium. This initial anisotropy is largely a consequence of the ellipsoidal shape of the overlap region between the two colliding nuclei. Higher order anisotropy (triangular, rectangular etc.) is the consequence of fluctuations of the shape of the nuclei. Anisotropic flow is expressed by the coefficients of the harmonic decomposition of the anisotropy of the produced particles. Flow is a unique observable, sensitive to the early properties of the created system. The properties of the QGP like the shear viscosity per degree of freedom and expansion parameters are studied using relativistic hydrodynamical models. The integrated elliptic flow (the second harmonic coefficient) of charged particles in Pb-Pb collisions at the LHC with the energy of 2.76 TeV per nucleon pair measured with the ALICE detector is 30% larger than in Au-Au collisions at the relativistic heavy-ion collider (RHIC) with the energy of 200 GeV per nucleon pair, while the flow as function transverse momentum remains virtually the same. This observation is compatible with the predictions of some hydrodynamical models that account for viscous effects. The rise of the value of integrated flow is attributed to a higher value of the mean transverse momentum at the LHC. The measurement of elliptic flow of identified pions, kaons and anti-protons shows a larger mass splitting than in the RHIC measurement. This effect is associated with a higher expansion velocity of the medium (radial flow) and it provides an explanation for the higher mean transverse momentum at the LHC concluded from the rise of integrated flow. The third harmonic coefficient (triangular flow) of identified particles shows a weak centrality dependence conforming with the expectation that higher order anisotropies are caused by fluctuations of the initial conditions. Qualitative similarities with elliptic flow (like mass ordering) support the idea that the mechanism responsible for the higher order momentum anisotropies of the produced particles is similar to that of elliptic flow. The elliptic and triangular flow data seems to favour hydrodynamical models with a very low value of viscosity, close to the conjectured theoretical minimum; a quantitative description needs more theoretical and experimental research. The transverse energy scaling of flow per constituent quark observed at RHIC is broken for elliptic flow en only holds approximately for triangular flow. The idea that quark coalescence is a dominant hadronization mechanism in Pb-Pb collisions at the LHC is difficult to defend; many different processes probably play a role. Also in this case further theory advancements are needed to describe this system quantitatively
Dielectron production at midrapidity at low transverse momentum in peripheral and semi-peripheral Pb–Pb collisions at √sNN = 5.02 TeV
No full textThe first measurement of the e+e− pair production at low lepton pair transverse momentum (p T,ee) and low invariant mass (m ee) in non-central Pb–Pb collisions at sNN = 5.02 TeV at the LHC is presented. The dielectron production is studied with the ALICE detector at midrapidity (|η e | < 0.8) as a function of invariant mass (0.4 ≤ m ee < 2.7 GeV/c 2) in the 50–70% and 70–90% centrality classes for p T,ee < 0.1 GeV/c, and as a function of p T,ee in three m ee intervals in the most peripheral Pb–Pb collisions. Below a p T,ee of 0.1 GeV/c, a clear excess of e+e− pairs is found compared to the expectations from known hadronic sources and predictions of thermal radiation from the medium. The m ee excess spectra are reproduced, within uncertainties, by different predictions of the photon–photon production of dielectrons, where the photons originate from the extremely strong electromagnetic fields generated by the highly Lorentz-contracted Pb nuclei. Lowest-order quantum electrodynamic (QED) calculations, as well as a model that takes into account the impact-parameter dependence of the average transverse momentum of the photons, also provide a good description of the p T,ee spectra. The measured 〈pT,ee2〉 of the excess p T,ee spectrum in peripheral Pb–Pb collisions is found to be comparable to the values observed previously at RHIC in a similar phase-space region.
