The Greek telecommunications industry is described for the first time following the Structure-Conduct-Performance (SCP) paradigm of Industrial Organisation (IO), as a methodological tool of analysis. In that respect, an SCP model in its extended form is constructed, aiming to examine how structure, conduct, and performance interrelate to each other. More precisely, the SCP model explains how strategic decisions regarding tower infrastructure sharing between 2013-2022 were developed, as a result of a series of interactions and feedback effects, amongst market structure, operators' conducts, and performances, resulting in strengthening competition and reshaping market structure with the entrance of a new player in the Greek mobile market, an independent TowerCo (Athens, Greece) in Greece. International tendencies and competition issues influencing domestic growth potentialities and alternative operators' concentration will be addressed, too. The paper concludes with presenting a basically qualitative, explanatory interpretive analysis of the perspectives of network tower-sharing analysis in the Greek telecommunication industry, including policy recommendations for the near future and thoughts on future research, as well.

By raising intercultural awareness and acquiring intercultural competence the ultimate goals are achieved for a more inclusive public school. A self-administered questionnaire was applied randomly to collect data from primary and secondary education teachers at public schools in West Attica. A total of 160 teachers having different specialties participated in the study. The results showed a statistically significant relationship between the level of education and the possibility of applying intercultural practices in the classroom. Furthermore, a statistically significant relationship exists between teaching experience and appropriate information on Intercultural Education. All the respondents highlighted the benefits of using intercultural practices in the classroom but they seldom include intercultural practices in their teaching sessions. More than half of the respondents consider that the curricula should be changed and the educational material should be adapted and revised. Public school teachers support for intercultural education, but they consider important a change in the curricula, the teaching material and the teaching methods. Also, a change is required on the methods of training teachers so as they will become a liaison between school and society.

Especially mobile market has been the field of implementation for new strategies regarding customer satisfaction and business productivity. This research aims to enlight the relationship between customer satisfaction and business productivity in the Greek mobile market. A quantitative methodology and actual data about mobile services usage were adopted to evaluate customers' satisfaction. Moreover, a series of productivity and customers' satisfaction indexes were used to confirm research hypotheses. Results indicate that market penetration plays crucial role, by providing interconnection with other users through the same mobile network. Proposed research provides evidence about why, in the current digital era, social media as a means of interconnection between end-users seem to constantly play more and more significant role in their daily communication.

It is the generation that makes its first working steps in a global economic environment heavily affected by Covid-19 consequences and digital transformation's influence. Empirical studies conducted provide results that vary across national cultures indicating the need for research in different countries, especially when it comes to Greek Generation Z for which little is known. This study contributes by providing a new approach when investigating entrepreneurial intention, by investigating Greek university students' work values and grit. A convenience sample of 255 business administration students were surveyed in terms of their entrepreneurial intention. Grit, extrinsic and intrinsic work values, alongside social values are studied to understand student entrepreneurial intention, while results indicate that only grit has a positive and statistically significant effect on entrepreneurial intention. Results are useful for higher education's stakeholders and for employers seeking to attract and to effectively integrate Generation's Z employees to their organizations.

Despite the increasing number of these programs offered worldwide, their effectiveness remains to be determined. Research has produced mixed outcomes, and there needs to be a consensus on the definition of entrepreneurship education in incubators or the outcomes of such courses. The perception of business incubators has evolved to become supportive settings for new business ventures and aspiring entrepreneurs. They are considered the future training grounds for entrepreneurship and experimental hubs for learning. Nevertheless, the degree to which they enhance business performance is debatable, and research into their outcomes needs to be more varied and largely inconclusive. The research methodology employed in this study is quantitative and involves a questionnaire. The sample consists of 112 start-ups and visionary entrepreneurs that have participated in entrepreneurship education programs offered by the incubators in Greece, and 21 business incubators. The results of the study show that entrepreneurship education programs have the potential to enhance specific skills and attitudes in participants that could be advantageous in the long run. While the research does not provide conclusive evidence, it does demonstrate promising correlations. Therefore, although business incubatorbased entrepreneurship education programs in Greece may not immediately impact start-ups, they could be advantageous in the future.

Even though such technologies are common to museums, galleries and archaeological places all over the world, little research or practical cases have been developed when it comes to theaters and theatrical costumes. The proposed research article describes the methodology of both reference material collection and application development, while an analysis of functions and aesthetic results are described, especially when it comes to 3D modeling. This paper’s aim is to reveal that theatrical operations (as part of the cultural sector) as well as structured parts (such as acts, performances and costumes) can be preserved and served to larger audiences via technological means, such as an augmented reality application.

Wearable technologies are a popular application of IoT and can potentially affect users' lifestyles, health, wellbeing, behaviors, and decisions. Smartwatches are the most popular type of wearable device among athletes. We are interested in the factors influencing the adoption of smart devices which monitor and track sports and fitness activities. Our data was based on a convenient sample of 128 amateur runners and we performed descriptive statistics and regression analysis. We applied the theoretical model of Technology Acceptance and empirical results reveal that perceived usefulness, perceived ease of use, and smartwatch health indications, are notable antecedents of someone's decision to adopt a smart device. Sport wearable companies may get insights from this research about significant factors of smartwatch adoption and products to help athletes enhance their performance.

Moreover, the way culture affects the success and failure of a series of enterprising practices, such as mergers, acquisitions, strategic alliances and joint ventures is presented. All these create a rather interesting framework in which organizational managers should cultivate and implement the appropriate organizational culture in order to keep their organization competitive and well managed. Finally, case studies from the telecommunications industry will be presented, a field where culture plays a dominant role in either changing procedure or in developing new enterprising practices.

The research issue of digital transformation has been attracting considerable interest among academics and business practicians since COVID-19 accelerated the procedure of implementing Industry 4.0 principles all over global economies. Quantitative research on 147 Greek SMEs revealed the most important issues on how these businesses implement digital transformation, factors accelerating or decelerating the process, barriers and expected outcomes. The results indicate that digital maturity, digital transformation strategy and digital business models are strongly interconnected, while the main barriers of successfully implementing them is a lack of funding, cultural issues and the management’s engagement with the whole procedure. Greek SMEs a...

A key in reaching that goal lies on flexible methodologies that affect strategic management. The chapter's aim is to research on aspects related with Scrum's implementation and productivity/quality achieved, where a need for constant research exists. Systematic literature review was conducted in order to choose the most relevant studies and to code the key words and themes that seem most important to address this relationship, while two interviews with Scrum's experts came to provide empirical information. The most important aspects for successful agile methodologies' adoption are presented, while results indicate that “adoption” and “perception” seem to be the most critical factors for its successful implementation. Moreover, a widespread extended misconception about agile methodologies is pres...

A group of visitors played the game “Find the Artwork behind the Story!”, crafting stories over the displayed artworks and sharing their thoughts, reasoning and emotions. Then the artist, Stefanos Rokos, joined the group and a new game round was played. We investigate how the artist’s participation affected the group experience, examining both the visitors’ and the artist’s perspective. Our findings show that the visitors were willing to share their stories and highly appreciated their gameful interaction with the artist. We observed that the artist behaved similarly to the rest of the players, rejecting our hypothesis that he would take on a leading role in the discussions. The artist expressed his enthusiasm for the game experience, stating that his partic...

However, the participation of cultural creators is hardly explored. In this paper we examine how the artists may participate in storytelling games played over their artworks. We present a field study at a museum exhibition, where the artist joined a group of visitors crafting and sharing stories over his paintings. We investigate how the artist's participation affected the group experience, considering the visitors' perspective along with the artist's. Both sides reported positive outcomes, indicating an engaging social cultural experience. Furthermore, we discuss the effects of bystanders in traditional as opposed to game-event settings. Building upon the later, we pinpoint limitations and challenges over the artist's participation, and explore varying levels of engagement, sketching good practices and new directions.

This exploitation is also essential in facilitating the presentation of cultural works and exhibits to a broader audience. Consequently, in this work, we propose a custom-developed digital repository that functions as software-as-a-service (SaaS), primarily promoting the safe storage, display, and sharing of cultural materials; enhancing accessibility; and fostering a deeper understanding and appreciation of cultural heritage. The proposed digital repository service is designed as a multitenant architecture, which enables organizations to expand their reach, enhance accessibility, foster collaboration, and ensure the preservation of their content. Moreover, our technology stack incorporates robust and reliable backend technologies, such as Django, to ensure data security and efficient management. Meanwhile, the front...

Τα σημαντικότερα εκ των αποτελεσμάτων αναδεικνύουν την απουσία του διλήμματος ασφαλείας όταν εξετάζονται οι συνολικές αμυντικές δαπάνες των δύο χωρών. Αντίθετα όταν εφαρμόζεται η offence – defense theory (εξοπλιστικές δαπάνες) το δίλημμα ασφαλείας εμφανίζεται να υφίσταται για την περίοδο 1996-2007. Η Τουρκία έχει συσχετίσει την άμυνα της με τη μεγέθυνση της οικονομίας της, αλλά παράλληλα και με τις εσωτερικές της εξελίξεις στον τομέα του εκδημοκρατισμού. Αντίθετα, η Ελλάδα δεν παρουσιάσει στατιστικά σημαντικές συσχετίσεις των αμυντικών μεγεθών της, ούτε με την οικονομία της, ούτε με τους δείκτες εκδημοκρατισμού.
Οι λόγοι που οι ανωτέρω τρεις κατηγορίες «δανειστών» συμμετέχουν στις διεθνείς χρηματοοικονομικές αγορές ποικίλουν και αφορούν (ενδεικτικά) την επίτευξη κέρδους, τον αποθησαυρισμό, τη δημιουργία χαρτοφυλακίων χαμηλού / υψηλού ρίσκου, την περαιτέρω υποστήριξη κάποιας αρχικής επένδυσης, την απόκτηση επιρροής σε κάποια οικονομία κ.α. Από την άλλη πλευρά, οι κυβερνήσεις των κρατών συνεχίζουν να δανείζονται για να μπορούν να χρηματοδοτούν δημόσια έργα, αμυντικές δαπάνες, κοινωνική ευημερία και φυσικά για να αποπληρώνουν παλαιότερα δάνεια τους.
Η σύζευξη προσφοράς και ζήτησης χρηματοοικονομικών πόρων δημιούργησε το παράδοξο της πλήρους σχεδόν υποθήκευσης του παγκόσμιου πλούτου που παράγεται σε ένα έτος (εκτόξευση του παγκόσμιου δημόσιου χρέους), γεγονός που υποθηκεύει τη δυνατότητα των κρατών να ασκούν ’ανεξάρτητη, κυρίαρχη πολιτική’ προς όφελος των πολιτών τους. Κριτική ασκείται στη διαφαινόμενη ισχύ των αγορών χρήματος και κεφαλαίου να ’επιβάλουν’ τις επιλογές τους επί των κρατών. Ή μήπως αυτό δεν ισχύει;
