Acheloos river gave in the past and continues to give, through a long series of decisions concerning its management, triggered intense debate on the management of water resources and to address the "god River" from the state, the law, and society, and in our country the issue of water is not insignificant. Water shortage in Thessaly was a problem known from the beginning of last century. The intention of solving the problem was stated by all the governments and the wider consensus of political parties. In 1960 we held the first diversion of a tributary of Acheloos, Tavropos. Strong reactions are then created from the local community, they have now forgotten. The contribution of Lake Plastira in the local and national economy is now unmistakable. The 2nd Diversion of Acheloos was announced in 1980 and it was decided in 1983. Since then they have spent forty-two (42) years and the work is not yet complete. The project has divided and the debate between those who through documented studies supporting the project and those who rely on negative environmental impacts but does not support analog validity studies. Written at times too many essayw and not always entirely accurate even in the international press, with regard to technical, economic, legal, environmental and political dimension of the project. In this study reflected the reality of the works of the second diversion of Acheloos in all its dimensions, The reality of such projects will emerge in this paper impose and taking all those measures that will ensure the optimal performance already invested money of Greek taxpayers, in accordance with the terms of a viable and sustainable development.
This study proposes a new conceptual framework for investigating the reasons, why manufacturing firms decide to invest on the acquisition of new machinery and equipment in order to improve their infrastructure. It incorporates various product related factors. The main goal is to examine how all these factors affect the investment decision making process. Therefore, a new, composite model is proposed. This model empirically examines the relationships between those practices, as well as their impact on machinery and equipment investments and on business performance. To carry out this research a survey research strategy was followed. The sample frame for this study consisted of Greek firms that belong to the manufacturing sector of Greek economy, which employ at least 20 employees. The final research sample was consisted of 248 questionnaires from businesses that have invested through the five past years. Descriptive statistics as well as Structure Equation Modeling (SEM) techniques we...
Η συνθετική πρακτική της φανταστικής κοσμοπλασίας
2021
Στην παρούσα εργασία εξετάζεται η πρακτική της κοσμοπλασίας (worldbuilding), η χρήση δηλαδή καλλιτεχνικών μέσων (λογοτεχνία, οπτικές τέχνες κ.α.) για την κατασκευή και παρουσίαση κόσμων. Αρχικά γίνεται μια προσπάθεια να εντοπιστούν οι θεμελιώδεις συνθετικές αρχές που διέπουν την κοσμοπλασία. Οι αρχές αυτές εξετάζονται στο context της fantasy λογοτεχνίας, ως κατεξοχήν πεδίο εφαρμογής και ανάπτυξης της συνθετικής αυτής πρακτικής. Χρησιμοποιώντας παραδείγματα από δύο από τα πιο επηρεαστικά κείμενα αυτής της παράδοσης (το Σιλμαρίλλιον του J. R. R. Tolkien και το έπος της Γαιοθάλασσας της U. K. Le Guin), η εργασία αποσκοπεί να σκιαγραφηθούν εκείνες οι πλευρές που αποδίδουν στα έργα μια συγκεκριμένη «κοσμικότητα» (worldness), καθώς και οι συνθετικές αρχές που τις παράγουν. Στην παρούσα έρευνα υποστηρίζεται πως η κατασκευή κόσμων μπορεί να εννοηθεί ως μια συνθετική πρακτική που εμφυσά σε κατασκευασμένα σύνολα σαφείς εννοιολογικές συσχετίσεις και νοηματοδοτικές σχέσεις, οι οποίες δημιουργούν με το κοινό μια σχέση κατοίκησης. Με την ανάλυση των δύο παραδειγμάτων, επισημαίνεται ότι η κατανόηση αυτών των νοηματοδοτικών πλαισίων εκφράζεται μέσα από συνθετικά σύνολα (θεματικές σχέσεις, χωρικές διαμορφώσεις, μοτίβα αφηγηματικά και μη ...). Η κοσμοπλασία, ιδωμένη ως χτίσιμο ενός περιβάλλοντος βάσει κάποιων ιδεών και επανεξέταση αυτών σύμφωνα με τα συμπεράσματα που προκύπτουν από την κατοίκηση του εν λόγω περιβάλλοντος, αναδεικνύεται ως ένα χρήσιμο σχεδιαστικό εργαλείο.
