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 ...

Δεν παρατίθεται περίληψη στα ελληνικά. ; Kostas Raptis, Merchants in Imperial Austria during the 'Long' Nine­teenth Century This article, which draws mainly on the Archives of the Austrian Ministry of Commerce, as well as on contemporary works and modern li­ terature, focuses on the examination of the historical course of merchants (above all the whole sale traders and the well suited shopkeepers and retail merchants) in Old Austria as a distinctive group within the Central European bourgeoisie. The contribution of the merchant­magnates (Großhändler) to the industrialization of the Austrian Half of the Habsburg Empire and the formation of a powerful business class, the importance of the involvement of businessmen from abroad in Austrian wholesale and foreign trade, the grip of the state and imperial allegiance in the commercial sector, the social position and the political activity of merchants– primarily at local and regional levels –as well as the attitudes of the multi­ethnic merchant class towards all kinds of nationalist movements in the late nineteenth and the early twentieth centuries, are the central issues of this essay. Merchant­magnates, among whom many of foreign provenance or/ and not of Catholic faith (Protestants, Jews and Greek­orthodox) established themselves as the most active entrepreneurial group within the Austrian bourgeoisie during most of the nineteenth century (at least until the 1870s), since they exploited promptly every new opportunity to accumulate and augment their capital and income: in industry, banking, insurance and other share­holding companies, transport, shipping and real estate. The bourgeois status of the Austrian merchants is confirmed for the same period by their participation in all sorts of (bourgeois) associations, their subscription to public benefit causes, their charitable and philanthropic activities. The imperial state's favorable disposition towards entrepreneurs in general and merchants in particular, its recognition and reward of their contribution to the Austrian economy and export trade, of their mercantile knowledge and professional experience, as well as of their charity and philanthropic work, are documented in the appointment of honorary consuls of Austria abroad or of consuls of foreign states in the capital and cities of the Monarchy, the conferring of the highest social distinctions on merchants by Emperor Franz Joseph through award of medals, honorary titles and titles of nobility or the merchants' collaboration with the Ministry of Commerce as elected members and officials of chambers of commerce, as experts, special advisers and commission agents. In addition to the merchants' indirect relations with politics there were direct ones too, in other words their active participation as elected representatives, primarily to municipal councils and secondarily to the local and imperial parliaments of Austria after the constitutional reforms of 1860­1861. During the so­called era of liberalism, from the 1860s up to the mid­1880's, it was mainly german­speaking merchants, who, together with industrialists and other middle class groups, dominated in most towns, whereas in the three decades which preceded the First World War –an era of increasing anti­semitism and nationalism– they had to share power with new emerging petit­bourgeois strata (among them many shopkeepers). The article concludes with a remark on the upheavals caused to the merchant world by the two World Wars and national­socialism, which destroyed the unified economic space of Austria­Hungary, nationalized its cosmopolitan bourgeoisie and finally led to the expulsion, material depravation or/and extermination of such a dynamic and prominent group, like the Jewish merchants and entrepreneurs, followed by the abolition of the capitalist economy by the new socialist regimes in Central and East­Central Europe after 1945.
