The dissemination of learning objects via the Internet in a smart way that meets the essential needs of learners could significantly improve the services offered by an e-learning system. A prerequisite for this is the adoption of an efficient framework for organising, describing and managing the available training materials. The various knowledge-organising systems that have been developed from time to time contribute to this objective, but are not the best solutions for each case. Therefore, through this work we are trying to distinguish the differences between the main knowledge representation structures and to identify the one best suited to modelling a field of knowledge in a machine-readable way. In this first attempt, we put in practice the knowledge organisation system which we believed to be predominant over others, in order to see its dynamics. Our ultimate goal is to make use of this technique in all aspects of a distance learning programme. ; Η διάχυση των μαθησιακών αντικειμένων μέσω του Διαδικτύου με τρόπο ευφυή, που να ανταποκρίνεται στις ουσιαστικές ανάγκες των εκπαιδευόμενων, θα μπορούσε να βελτιώσει σημαντικά τις προσφερόμενες υπηρεσίες ενός συστήματος ηλεκτρονικής μάθησης. Απαραίτητη προϋπόθεση για κάτι τέτοιο είναι η υιοθέτηση ενός αποδοτικού πλαισίου οργάνωσης, περιγραφής και διαχείρισης του διαθέσιμου εκπαιδευτικού υλικού. Τα διάφορα συστήματα οργάνωσης γνώσης που έχουν αναπτυχθεί κατά καιρούς αφενός συμβάλλουν στην επίτευξη αυτού του στόχου, ωστόσο δεν αποτελούν τις ιδανικότερες λύσεις για κάθε περίπτωση. Συνεπώς, μέσα από αυτήν την εργασία επιχειρούμε να διακρίνουμε τις διαφορές ανάμεσα στις κυριότερες δομές αναπαράστασης γνώσης και να εντοπίσουμε αυτή που ανταποκρίνεται ικανοποιητικότερα στην μοντελοποίηση ενός γνωστικού πεδίου με τρόπο μηχανικά αναγνώσιμο. Σε αυτή την πρώτη προσπάθεια, εφαρμόζουμε στην πράξη το σύστημα οργάνωσης γνώσης που κρίναμε ότι υπερτερεί έναντι των υπολοίπων, ώστε να διαπιστώσουμε τη δυναμική του. Απώτερο στόχο μας αποτελεί η αξιοποίηση αυτής της τεχνικής σε όλες ...
Despina Iosif, «Christianos ad Leonem». The Case of Perpetua Two Greek editions of the diary of Perpetua have recently appeared, one by Polymnia Athanassiadi and the other by Thanassis Georgiadis, both bound to attract attention. Perpetua lived at Thuburbo Minus, west of Carthage in North Africa. She was an upper class, well-educated Roman citizen, twenty-two years of age, newly married and mother of a baby boy, who converted to Christianity and chose martyrdom instead of sacrificing to the traditional gods of the Roman Empire. Her decision was interpreted as an insult to the gods and the emperors, and a direct challenge to the established order and resulted in her being sentenced to death to the beasts of the arena in Carthage in 203 CE. It was a well-established Roman belief that the traditional gods offered military victories, stability, prosperity and grandeur to the Roman people. In return and to secure the continuation of this benevolence, the Roman people carried certain strictly defined rites in honour of their gods. Pagan religion was less a matter of personal devotion than of national significance. The Christians despised the traditional gods, declaring that they did not exist or that they were malevolent demons and neglected or obstructed the traditional religious rites. This conduct disrupted the agreement the Romans had made with their gods and made the empire vulnerable. From the second century on, natural disasters were being attributed to the wrath of gods as a result of the Christian atheism and the hatred Christians allegedly had for the world. It is extremely fortunate that Perpetua's diary, which she kept while in prison awaiting her death, has survived. It is a bold, vivid and honest account of her prison life, her dreams and the hopeless efforts of her father to persuade her to conform and sacrifice. The fact that the text praised prophesy and placed martyrs above the established church hierarchy led scholars to believe that is was a Montanist product. Fourth and fifth century bishops felt uncomfortable with Perpetua's diary and surrounded it with homiletic commentaries. Instead of letting the text speak directly to the community of the faithful, they guided the understanding of words, subtly changing its messages, and controlled its dissemination. They made Perpetua less appealing as a role model and less threatening to the social order. The impression and fascination her diary exerted, however, remain unchanged. ; Despina Iosif, «Christianos ad Leonem».
