Η Πολιτική για την Εκκλησιαστική εκπαίδευση στη μεταπολιτευτική Ελλάδα.

Η παρούσα εργασία ασχολείται με τις προθέσεις και κυρίως τις επιλογές της ηγεσίας, πολιτικής και εκκλησιαστικής, και την εκπαιδευτική πολιτική που εφαρμόσθηκε στην δευτεροβάθμια εκπαίδευση, μετά την μεταπολίτευση στην Ελλάδα. Ερευνά όχι μόνο το νομικό και θεωρητικό πλαίσιο, αλλά με τη μέθοδο των συνεντεύξεων αποτυπώνει κυρίως τις απόψεις, τις στάσεις και τα αποτελέσματα αυτής της πολιτικής, των ηγετικών προσωπικοτήτων της Εκκλησίας και της Πολιτείας που ενεπλάκησαν στη διαμόρφωση αυτής. Θέτει δε ερευνητικά ερωτήματα, όσον αφορά, κατά πρώτον τη σχέση Εκκλησίας-Κράτους, την πολιτική και τη διοίκηση που ασκήθηκε στην Εκκλησιαστική εκπαίδευση, ερευνά την αποτελεσματικότητά των στόχων που ορίζονται από το νομικό πλαίσιο, το χαρακτήρα και την αποστολή της στην ελλαδική κοινωνία, το προφίλ των εκπαιδευτικών στελεχών σε σχέση με τις απαιτήσεις του ειδικού τύπου σχολείου και τέταρτον, κατά πόσον η επιλογή των μαθητών προσφάτως και μαθητριών, λειτούργησαν προς όφελος των ιδίων και των σκοπών της Εκκλησιαστικής εκπαίδευσης. Τέλος, αποτιμά το σύνολο των πολιτικών και πρακτικών, κατά πόσον αυτές πέτυχαν τους στόχους τους αποτυπώνοντας τη σημερινή κατάσταση και το όραμα των ηγετών της Εκκλησιαστικής εκπαίδευσης καθώς και την μεταξύ τους απόκλιση. Από την έρευνα προέκυψε ότι ο ρόλος της Εκκλησίας στην Εκκλησιαστική εκπαίδευση είναι περιορισμένος και μόνο γνωμοδοτικός. Ο χαρακτήρας της εκπαίδευσης ελέγχεται για την εκκλησιαστικότητά της, ενώ η αποτελεσματικότητα κρίνεται ανεπαρκής ως προς το σκοπό που νομοθετικά έχει καθορισθεί. Στο τομέα που αφορά το έμψυχο δυναμικό, τόσο τους εκπαιδευτικούς όσο και τους μαθητές διαπιστώθηκε έλλειμμα στην εξυπηρέτηση των στόχων και απουσία εκπαιδευτικού αποτελέσματος. Κατά την έρευνα διαπιστώθηκε ότι τις περισσότερες φορές απουσίαζε από την ηγεσία ο συντονισμός και ο έλεγχος, αλλά ιδιαίτερα, απουσίαζε ο σχεδιασμός, κυρίως ο μακροπρόθεσμος.This thesis deals with the intentions but mainly the leadership choices, political and ecclesiastical, and educational policy applied in secondary education particularly after the junta in Greece. Investigated not only the legal and conceptual framework, but the interview process mainly captured the views, attitudes and the results of this policy, the leading persons of the Church and the State involved in this configuration. Set research questions concerning first the Church-State relationship in relation to the policy and management brought in Ecclesiastical Education and its effectiveness in relation to the objectives defined by the legal framework, its nature and mission, at the Greek society, the educational staff profile compared with the requirements of a specific school type and the last one, whether the choice of students and female students recently, worked for the benefit of themselves and the objectives of ecclesiastical education . Finally evaluate all policies and practices, whether they achieved their goals and reflects the current situation and the vision of current leaders of ecclesiastical education and the deviation between them. The investigation revealed that the role of the Synod in ecclesiastical education is limited and only advisory; the education is contested for the ecclesiastical character, at the same time the effectiveness of this is insufficient in terms of objectives that is legally defined. In the research component involving the workforce, both teachers and students found a deficit in the service of objectives and lack of educational outcome. The survey found that most of the time coordination and control was absent from management, but more than any other, there was no planning, especially long-term

Ανάπτυξη συστημάτων και αλγορίθμων σκανδαλισμού για το πείραμα CMS στον επιταχυντή HL-LHC του CERN

The CMS experiment is being prepared for the Phase-2 era, when the High-Luminosity LHC (HL-LHC) will start its operations delivering more than 7 times the nominal LHC Luminosity. The aim of the CMS upgrade is both to maintain but also improve the detector performance, in order to extend the discovery reach of the detector. The amount and density of data produced by HL-LHC demands new detector systems, replacement of the majority of the on-detector electronics, and complete replacement of the Trigger system. The work of this thesis is part of the CMS Level-1 Trigger upgrade. The first part of the work was devoted to the development of an optical link protocol, operating at 25 Gbps and targeting FPGAs produced by Xilinx. The protocol will be the standard Phase-2 protocol, used by the Level-1 Trigger processors for their internal data exchange. A detailed description of its firmware implementation, as well as results of extended testing are presented. Moreover, the work here includes firmware developments that target the Barrel Muon Trigger Layer-1 subsystem, responsible for the generation of track segments of muons that cross the barrel region of CMS. An ATCA card based on a VU13P FPGA was designed to instrument this system. The design of certain modules of this card, as well as the development of its firmware infrastructure and the slice tests that demonstrated its performance using data from proton-proton collisions are presented in the second part of this thesis.Το πείραμα CMS προετοιμάζεται για την δεύτερη περίοδο λειτουργίας του (Phase-2), όπου ο επιταχυντής High-Luminosity LHC (HL-LHC) θα ξεκινήσει να λειτουργεί παράγοντας περισσότερο από 7 φορές την ονομαστική φωτεινότητα του LHC. Ο στόχος της αναβάθμισης του CMS αφορά την διατήρηση και βελτίωση της επίδοσης του ανιχνευτή, ώστε να επεκταθεί το πεδίο ανακάλυψης του ανιχνευτή. Ο ποσότητα των δεδομένων που παράγονται από τον HL-LHC απαιτεί νέα ανιχνευτικά συστήματα, αντικατάσταση της πλειοψηφίας των ηλεκτρονικών τους, καθώς και την εξ ολοκλήρου αντικατάσταση του συστήματος Σκανδαλισμού (Trigger). Η δουλειά της παρούσας εργασίας αφορά μέρος της αναβάθμισης του Συστήματος Σκανδαλισμού Επιπέδου-1 του CMS. Το πρώτο μέρος της αφορά την ανάπτυξη ενός οπτικού πρωτοκόλλου για μεταφορά δεδομένων σε ταχύτητες έως 25 Gbps, το οποίο λειτουργεί σε FPGA της εταιρίας Xilinx. Το πρωτόκολλο αυτό έχει καθιερωθεί για την περίοδο του Phase-2, και θα χρησιμοποιηθεί από όλους τους επεξεργαστές του Σκανδαλισμού Επιπέδου-1 για την μεταξύ τους επικοινωνία. Εδώ παρουσιάζεται λεπτομερώς η δομή του, καθώς και αποτελέσματα από ενδελεχείς δοκιμές. Επιπρόσθετα, η εργασία αυτή περιλαμβάνει την ανάπτυξη υλικολογισμικού για τo υποσύστημα Barrel Muon Trigger Layer-1, το οποίο ανιχνεύει Μιόνια στην περιοχή του βαρελιού του CMS. Το υποσύστημα θα στελεχωθεί με μία κάρτα-επεξεργαστή, βασισμένη στο FPGA VU13P. Εδώ περιγράφεται ο σχεδιασμός συγκεκριμένων στοιχείων της κάρτας, η λογική υποδομής της, καθώς και οι δοκιμές που ανέδειξαν την λειτουργία της σε περιβάλλον πραγματικών συγκρούσεων πρωτονίων

Two-particle Bose-Einstein correlations and their Lévy parameters in PbPb collisions at sNN\sqrt{s_\mathrm{NN}} = 5.02 TeV

Two-particle Bose-Einstein momentum correlation functions are studied for charged-hadron pairs in lead-lead collisions at a center-of-mass energy per nucleon pair of $\sqrt{s_\mathrm{NN}}$ = 5.02 TeV. The data sample, containing 4.27$\times10^{9}$ minimum bias events corresponding to an integrated luminosity of 0.607 nb$^{-1}$, was collected by the CMS experiment in 2018. The experimental results are discussed in terms of a L\'evy-type source distribution. The parameters of this distribution are extracted as functions of particle pair average transverse mass and collision centrality. These parameters include the L\'evy index or shape parameter ($\alpha$), the L\'evy scale parameter ($R$), and the correlation strength parameter ($\lambda$). The source shape, characterized by $\alpha$, is found to be neither Cauchy nor Gaussian, implying the need for a full L\'evy analysis. Similarly to what was previously found for systems characterized by Gaussian source radii, a hydrodynamical scaling is observed for the L\'evy $R$ parameter. The $\lambda$ parameter is studied in terms of the core-halo model.Comment: Submitted to Physical Review C.

Measurement of the double-differential inclusive jet cross section in proton-proton collisions at s\sqrt{s} = 5.02 TeV

International audienceThe inclusive jet cross section is measured as a function of jet transverse momentum $p_\mathrm{T}$ and rapidity $y$. The measurement is performed using proton-proton collision data at $\sqrt{s}$ = 5.02 TeV, recorded by the CMS experiment at the LHC, corresponding to an integrated luminosity of 27.4 pb$^{-1}$. The jets are reconstructed with the anti-$k_\mathrm{T}$ algorithm using a distance parameter of $R$ = 0.4, within the rapidity interval $\lvert y\rvert$$\lt$ 2, and across the kinematic range 0.06 $\lt$$p_\mathrm{T}$$\lt$ 1 TeV. The jet cross section is unfolded from detector to particle level using the determined jet response and resolution. The results are compared to predictions of perturbative quantum chromodynamics, calculated at both next-to-leading order and next-to-next-to-leading order. The predictions are corrected for nonperturbative effects, and presented for a variety of parton distribution functions and choices of the renormalization/factorization scales and the strong coupling $\alpha_\mathrm{S}$

Measurement of the Drell-Yan forward-backward asymmetry at high dilepton masses in proton-proton collisions at s\sqrt{s} = 13 TeV

A measurement of the forward-backward asymmetry of pairs of oppositely charged leptons (dimuons and dielectrons) produced by the Drell-­Yan process in proton-proton collisions is presented. The data sample corresponds to an integrated luminosity of 138 fb$^{-1}$ collected with the CMS detector at the LHC at a center-of-mass energy of 13 TeV. The asymmetry is measured as a function of lepton pair mass for masses larger than 170\GeV and compared with standard model predictions. An inclusive measurement across both channels and the full mass range yields an asymmetry of 0.599 $\pm$ 0.005 (stat) $\pm$ 0.007 (syst). As a test of lepton flavor universality, the difference between the dimuon and dielectron asymmetries is measured as well. No statistically significant deviations from standard model predictions are observed. The measurements are used to set limits on the presence of additional gauge bosons. For a Z' in the sequential standard model, a lower mass limit of 4.4 TeV is set at 95% confidence level

Observation of the Bc+_\mathrm{c}^+ meson in PbPb and pp collisions at sNN\sqrt{s_{\mathrm{NN}}} = 5.02 TeV

The B$_\mathrm{c}^+$ meson is observed for the first time in heavy ion collisions. Data from the CMS detector are used to measure the production of the B$_\mathrm{c}^+$ meson in lead-lead (PbPb) and proton-proton (pp) collisions at a center-of-mass energy per nucleon pair of $\sqrt{s_{\mathrm{NN}}}$ = 5.02 TeV, via the B$_\mathrm{c}^+$$\to$ (J/$\psi$$\to$$\mu^+\mu^-$)$\mu^+\nu_\mu$ decay. The B$_\mathrm{c}^+$ nuclear modification factor, derived from the PbPb-to-pp ratio of production cross sections, is measured in two bins of the trimuon transverse momentum and of the PbPb collision centrality. The B$_\mathrm{c}^+$ meson is shown to be less suppressed than other quarkonia and most of the open heavy-flavor mesons, suggesting that effects of the hot and dense nuclear matter created in heavy ion collisions contribute to its production. This first observation of the B$_\mathrm{c}^+$ meson in heavy ion collisions sets forth a new promising probe of the interplay of suppression and enhancement mechanisms in the production of heavy-flavor mesons in the quark-gluon plasma
