Αποτύπωση της αντίληψης της ελληνικής κοινής γνώμης σε σχέση με τις επιδόσεις και την αποτελεσματικότητα του υφιστάμενου εθνικού πλαισίου»(Σχολή Διοίκησης Επιχειρήσεων : Τμήμα Διοίκησης Επιχειρήσεων : Μεταπτυχιακό στην Διοίκηση Επιχειρήσεων, 2024-05-18)Η παρούσα μεταπτυχιακή εργασία αποβλέπει στην πολύπλευρη ενημέρωση του αναγνώστη σχετικά με το ξέπλυμα βρώμικου χρήματος από παράνομες δραστηριότητες σε επίπεδο ελληνικής κι ευρωπαϊκής πραγματικότητας. Περιγράφεται το φαινόμενο και οι εκφάνσεις του, ενώ ανασκοπείται το εθνικό, ευρωπαϊκό και διεθνές νομικό πλαίσιο. Προσδιορίζονται συγκεκριμένα ερευνητικά προβλήματα τα οποία μελετώνται μέσω βιβλιογραφικής ανασκόπησης, ερωτηματολογίου κοινής γνώμης και συνεντεύξεων ειδικών. Το ξέπλυμα βρώμικου χρήματος έχει σαφείς πολιτικές και οικονομικές προεκτάσεις σε παγκόσμιο επίπεδο, με εκτεταμένο αντίκτυπο στις κοινωνικές δομές. Η αντιμετώπισή του είναι δύσκολη λόγω της ίδιας του της φύσης η οποία τροφοδοτείται από το εγκληματικό στοιχείο, με αποτέλεσμα να εξελίσσεται αενάως. Παρά την πληθώρα θεσμικών πλεγμάτων και νομικών πλαισίων, η παντελής εξάλειψή του δεν έχει ακόμα επιτευχθεί αφού πολλές φορές οι όποιοι μηχανισμοί καταπολέμησής του κρίνονται ανεπαρκείς. Προκύπτει ότι η αποτελεσματικότητα του ελληνικού πλαισίου εξαρτάται άμεσα από τους εθνικούς μηχανισμούς ελέγχου και πρόληψης, την ευρύτερη κρατική μηχανή υπό το πρίσμα της διαφθοράς, της πολιτικής βούλησης και του βαθμού επιβολής του νόμου, αλλά και από τη συμβατότητα και πλήρη εναρμόνισή του με το αντίστοιχο ευρωπαϊκό. Διακρίνεται δε από συγκεκριμένες διαχρονικές παθογένειες που το καθιστούν τρωτό σε απειλές κι ενέχουν κινδύνους. Παρότι χαρακτηρίζεται από βασικές, «ικανοποιητικές» επιδόσεις, πάσχει στην απαρέγκλιτη εφαρμογή του κι αποτελεί διαρκώς αντικείμενο συζήτησης. Παρατηρούνται σημαντικά περιθώρια περαιτέρω βελτίωσης που απαιτούν όμως στοχευμένες παρεμβάσεις.
- PublicationEmployee empowerment practices : the impact on employee satisfaction(School of Business : Master of Business Administration, 2027-07-31)Οι οργανισμοί αντιμετωπίζουν τεράστιες προκλήσεις στη βελτίωση της απόδοσης και της παραγωγικότητάς τους στον σημερινό μεταβαλλόμενο και ανταγωνιστικό επιχειρηματικό κόσμο. Οι ειδικοί θεωρούν την ενδυνάμωση των εργαζομένων ως ένα αποτελεσματικό εργαλείο που ενισχύει την οργανωτική απόδοση, την ικανοποίηση των εργαζομένων και την ποιότητα των υπηρεσιών. Η απάντηση στη συνεχή μεταβαλλόμενη τάση της παγκόσμιας επιχειρηματικής ατμόσφαιρας είναι ίσως η πιο σημαντική ανησυχία τόσο για τους ανθρώπους όσο και για τους οργανισμούς. Προκειμένου να αντιδράσουν στις αλλαγές και τις διαφορετικές απαιτήσεις των πελατών και των ενδιαφερομένων, οι εργαζόμενοι πρέπει να αντιμετωπίσουν πολλές προκλήσεις στην καθοδήγηση της απόδοσής τους. Οι εργαζόμενοι συχνά αγωνίζονται να αρπάξουν και να περιορίσουν τη διαχειριστική τους εξουσία για να αντιμετωπίσουν αυτές τις προκλήσεις. Μία από τις βασικές προκλήσεις για τις επιχειρήσεις σε αυτήν την εποχή της παγκοσμιοποίησης είναι να παρέχει άμεσες απαντήσεις στους πελάτες για να τους κάνει ικανοποιημένους και να αυξήσει την παραγωγικότητα. Παρ 'όλα αυτά, οι κακές οργανωτικές ρυθμίσεις όπως η έλλειψη εξουσίας για λήψη αποφάσεων που σχετίζονται με την εργασία, περιορισμένη πρόσβαση σε πληροφορίες, έλλειψη ελέγχου στην εργασία, αόριστη και χωρίς νόημα ευθύνη, και το ακατάλληλο σύστημα ανταμοιβών συχνά καθιστούν τις θέσεις εργασίας δύσκολες για τους υπαλλήλους και μειώνουν την ποιότητα των υπηρεσιών, που τελικά οδηγούν σε δυσαρέσκεια των πελατών. Προκειμένου να κάνουν τους πελάτες ικανοποιημένους και να βελτιώσουν την οργανωτική απόδοση, οι οργανισμοί πρέπει να παρέχουν στους υπαλλήλους αρκετή εξουσία και υποστήριξη. Η παροχή υψηλής ποιότητας υπηρεσίας αποτελεί βασικό μέλημα για τις επιχειρήσεις, και ο Oliver υποστηρίζει ότι η ικανοποίηση των πελατών εξαρτάται κυρίως από την ποιότητα της προσφερόμενης υπηρεσίας. Η αντιληπτή εξυπηρέτηση πελατών μπορεί να προσδιοριστεί μόνο από την άποψη της παρεχόμενης ποιότητας υπηρεσίας και τη συνολική ικανοποίηση των εμπειριών των πελατών. Οι οργανισμοί μπορούν να επιλέξουν οποιαδήποτε από τις δύο προσεγγίσεις που μπορούν να ενισχύσουν την ποιότητα των υπηρεσιών: την προσέγγιση της γραμμής παραγωγής και την προσέγγιση ενδυνάμωσης. [
- PublicationWildfire Regimes and Governance Systems: Creating Urgency Without a Crisis(School of Computer Science : Department of Computer Science and Engineering : Program of Study Occupational Health and Safety, 2024-12-18)Amidst globally changing wildfire activity, increasing attention is focused on the role of the governance system as one component interacting with wildfire regimes and shaping their associated impact. Using an interdisciplinary approach with methods from the natural and the social sciences, the aim of this dissertation was to explore characteristics of governance systems for wildfire regimes theoretically and empirically based on two case studies. In Chapter 1, the significance of the problem was illustrated. A literature review was conducted to define key terms and to outline the rationale of why they are relevant for this work. The concepts of wildfire regimes and governance systems are set out and linked together, to explain how both are intertwined and interact as dynamic entities with physically measurable and socially constructed dimensions. Examples of recent work were introduced to summarise the state of art in the field, point out gaps in the literature, and to highlight this dissertation’s unique contribution to knowledge through the formulation of three research objectives. In Chapter 2, the methodological framework was introduced. To this end, the overall use of discourses methods was set out, together with a reasoning on temporal and spatial choices guiding the further research. An overview of material, methodologies and study design was provided for each research objective, to complement detailed methodology as provided in each respective Chapter. Ethical considerations were elaborated on, and followed by reflections on the limitations of this work such as existing biases due to the use of language, research scope, and deployed theory. The first research objective was investigated in Chapter 3, aiming to advance the field theoretically by systematically retrieving contributions from studies on governance systems for wildfire regimes to date. By engaging sampled work with recent advances in the broader field of natural resources scholarship, this approach allowed to identify components within governance systems that require closer attention. Four themes in the resulting analytical framework pointed to governance processes for actor participation, for collaboration and co-production, to the role of path-dependencies and local place-based characteristics, and of actor adaptation and anticipation. The four themes informed and guided the remaining, empirical research conducted in this dissertation. The second research objective was presented in Chapter 4, aiming to understand interactions across wildfire regimes and the governance system when focusing on regional and national level organizational structures. To this end, an empirical case study was developed and applied to examine the case of Italy. Qualitative data were collected across key stakeholder sectors to identify forces at play and conflicts of interest in the status quo. Survey respondents indicated satisfaction with the governance system mostly concentrated at regional levels that allows to account for variability in the wildfire regime at country-scale. At the same time, that responsibilities for wildfire mitigation and response were found to be fragmented across a range of decentralized institutions and network. While promising to develop locally adapted measures, the fragmented governance system poses coordination challenges across actors, organizational levels and sectors. The third research objective was examined in Chapter 5 with the aim to identify recurring governance opportunities for wildfire across different socio-ecological contexts and burning regimes. A targeted literature review of recently published high-level wildfire reports almost consistently revealed five wildfire challenges. This initial framing was then tracked back to analyze the case of Cyprus through policy analysis and qualitative data collection during a three-week internship at the Department of Forests during the 2023 fire season. Findings revealed well-established processes in the governance systems, but also deficits in wildfire thinking and action to anticipate predicted trends in wildfire regimes. Considering the size of the country, which is smaller than most regions in countries like Spain, Italy or Germany, the case served to study the potential for change in acting on and thinking of wildfire in a range of flammable landscapes and at local to national levels.
- Publication«Analysing the Interrelationships Among Employee Well- Being, Active Mobility, Organizational Commitment and Job Performance; A Circular Economy Approach»(School of Business Administration : Department of Business Administration : PHD Business Administration, 2024-06-27)Purpose: A growing number of studies have explored the potential benefits of employee wellbeing concerning employee active mobility, job satisfaction, and other aspects of job performance and organizational commitment. However, little has been done to investigate the benefits accrued for employees who use active mobility to commute to work, as well as the impact on employee well-being, job performance, and organizational commitment. As a result, a need emerges to assess current knowledge of this topic on linking employee wellbeing to job performance. This research investigates the correlations between employee wellbeing and other variables, such as employee active mobility, organizational commitment, and job performance. The scope of the present study is to examine the impact of employee active mobility (actively commuting to work) on employee wellbeing and job performance. Design/methodology/approach: Based on a Systematic Literature Review, a Causal Loop Diagram (CLD) was developed, following the System Dynamics Methodology, which was conducted on prominent studies on employee active mobility and its contribution to employee well-being and other aspects of job performance. Additionally, a conceptual model was developed to investigate employee active mobility and its influence on employee wellbeing and job performance. The research sample was drawn from employees who work in organizations, specifically those working in the Administration of the 1𝑠𝑡 Health Region of Attica under the Ministry of Health and Social Solidarity. The sample consisted of 303 employees. Also, an investigation was carried out on employees’ opinions by utilizing a Group Model Building (GMB) technique. Interviews with the participants were conducted to gain more accurate and specific data. The questionnaire was the instrument that was used for data collection. The questionnaire was located and selected using the composition of different questionnaires, modification of existing questionnaires, or selection through the international literature. Findings: This research provides a novel view of the dynamics of employee well being and job performance. This allows for further understanding of the links between employee active mobility and job performance, as well as the role and responsibility of organizations based on the costs, profit, and benefits to be gained. The present study revealed significant relationships between job performance and well-being, organizational commitment, and job satisfaction. Additionally, no statistically significant results occurred for the influence of employee active mobility on employee well-being, job performance, organizational commitment, and job satisfaction. Originality/value։ This review suggests that active mobility was not a significant factor in the explanation of employee well-being and job performance. However, a need emerges to clarify the factors which are preventing employees in Greece from commuting by walking or bicycle to work and the positive outcomes on employee well-being, job performance and organizational commitment.
- PublicationA Constructivist Grounded Theory on Education Policy and the Implications on the Formation of National Identity and the Political Concept of Cyprus(School of Humanities : Department of Social and Education Sciences Department of Education Sciences, 2023-11-12)This knowledge-oriented research in education aims to construct a Constructivist Grounded Theory (CGT) to theoretically best account for education policy discourse in the formation of the national identity and political concept of Cyprus from 2000 to 2018. This is a relatively unexplored period with the succession of four different governments with different ideological backgrounds and approaches to national identity during which significant political developments related to the Cyprus problem took place. I have applied CGT as the primary methodology and end product of this research with the support of the analytical dimensions of the Discourse Historical Approach (DHA) to critically explore the ways in which Greek Cypriot education policy actors exercise nationalism and attempt to construct national identity and the political concept of Cyprus. Using a top-down approach, I applied CGT fundamentals, defined by Kathy Charmaz, and aspects of DHA to the commemorative messages of education ministers from 2000 to 2018. The latter was supported by elite interviews with key education policy actors and other archival data. Within the political left-right spectrum, the ministerial commemorative messages of each government of the Republic of Cyprus (RoC) from 2000 to 2018 project specific policy positions in relation to the past, current status, and aspirations for Cyprus. The data analysis color the political context in which the schools operate and, more importantly, reveals the themes, discourse, and macro-strategies employed as an attempt to maintain, construct, justify, or dismantle national identity. In comparatively examining the data, this thesis concludes that governments and education policy actors occupy a powerful position in the socio-political construction and (re)construction of the discourses, concepts, and meanings of identity over time. The findings indicate that different identities are discursively constructed depending on the ideological and political premises of the respective government, the developments of the Cyprus Problem, and the vision of Cyprus. The significance of this study lies in the fact that it offers new theoretical insights into nationalism in the RoC between 2000 to 2018, not only on why nationalism emerges, but also on how nationalism functions over time through four successive governments, under what conditions a nation or a community is projected and mobilised, and how national identity is constructed through education policy discourse in the contemporary setting of time-space compression. In a data-driven manner, I also argue that nationalism is territorial and that, on this basis, the governments of the RoC seek to (re)produce territoriality, a continuing attachment to a particular land, by targeting the negotiation of symbolic national boundaries, spatial reconfiguration and national belonging in education policy. Special emphasis is placed on the ideological and political process of (re) producing the national land, be it the 'motherland' or the 'homeland' or even the 'special homeland'. In view of this, the construction of the inclusive 'us' and the exclusive ‘other' is also defined in territorial terms. Outputs from this study Maki, Ch. (2022), Territoriality in Education Policy.

- PublicationVitamin D daily short-term supplementation does not affect glycemic outcomes of patients with type 2 diabetes(2016-10-01)There is currently insufficient evidence of a beneficial effect to recommend vitamin D supplementation for optimizing glycemic status in patients with type 2 diabetes mellitus (T2DM). Taking into consideration the significant extra-skeletal effect of vitamin D on pancreatic β-cell function and insulin secretion and the large number of scientific evidence supporting the inverse association between vitamin D status and hyperglycemia, this review article aims to examine whether vitamin D supplementation therapies are beneficial to patients with T2DM considering specific factors through randomized controlled trials (RCTs). EBSCOhost and Medline databases were searched from the beginning of 2009 until the end of 2014 for RCTs in patients with T2DM. Parameters, such as baseline vitamin D levels, frequency/dosage of supplementation, length of the study and type of supplementation, were independently assessed, based on their effect on glycemic status. Although all different types of supplementation were safe and effective in the achievement of vitamin D sufficiency in a dose-dependent way, the impact on glycemic status was different. 14 RCTs were included with daily supplementations ranging from 400-11.200 IU/daily, 40.000-50.000 IU/weekly and 100.000-300.000 IU/intramuscularly or once given, for a period from 8 to 24 weeks. Daily supplementation of vitamin D (up to 11.200 IU) showed no effect, whereas combined supplementation, with calcium (≥300 mg), and with vitamin D doses similar to the RDA, showed positive effects. Additionally, high weekly doses of vitamin D (40.000-50.000 IU) were effective on glycemic outcomes but available data are limited.
- PublicationFunctional anatomy of the mandibular nerve: Consequences of nerve injury and entrapment(2011-03-01)Various anatomic structures including bone, muscle, or fibrous bands may entrap and potentially compress branches of the mandibular nerve (MN). The infratemporal fossa is a common location for MN compression and one of the most difficult regions of the skull to access surgically. Other potential sites for entrapment of the MN and its branches include, a totally or partially ossified pterygospinous or pterygoalar ligament, a large lamina of the lateral plate of the pterygoid process, the medial fibers of the lower belly of the lateral pterygoid muscle and the inner fibers of the medial pterygoid muscle. The clinical consequences of MN entrapment are dependent upon which branches are compressed. Compression of the MN motor branches can lead to paresis or weakness in the innervated muscles, whereas compression of the sensory branches can provoke neuralgia or paresthesia. Compression of one of the major branches of the MN, the lingual nerve (LN), is associated with numbness, hypoesthesia, or even anesthesia of the tongue, loss of taste in the anterior two thirds of the tongue, anesthesia of the lingual gums, pain, and speech articulation disorders. The aim of this article is to review, the anatomy of the MN and its major branches with relation to their vulnerability to entrapment. Because the LN expresses an increased vulnerability to entrapment neuropathies as a result of its anatomical location, frequent variations, as well as from irregular osseous, fibrous, or muscular irregularities in the region of the infratemporal fossa, particular emphasis is placed on the LN.
- PublicationThe education of Roma children: Challenges and promises(2016-12-12)The education of Roma children presents many challenges throughout the world because of poverty, issues of isolation and discrimination. In many countries where Roma reside, laws exist that prohibit discrimination against this minority group. A variety of conflicting issues exist for Roma children. On one hand, the Roma communities practice cultural norms that are in conflict with a typical schooling environment that requires significant structure and lack of independent support. Conversely, schools fail to provide appropriate bilingual instruction for Roma children who usually do not speak the local language. In most countries discrimination attitudes create segregated schools and insufficient social services. Many efforts and organizations are in place to positively impact these challenges to provide quality education for all Roma children.

- PublicationBarriers to innovation for SMEs in a small less developed country (Cyprus)(1999-01-01)The present research, conducted in Cyprus, a small less developed country, concentrates on the barriers approach to innovation. The importance of barriers, as perceived by the firms' owners/managers was, rather surprisingly, not statistically correlated either to innovativeness, economic performance or the extent of the horizontal networking. The study of barriers offers, nevertheless, some interesting clues to the innovation practice in small less developed countries. Some similarities with barriers in industrialized countries (e.g. in supply of finance and skilled labour) were found, but many differences as well, as expected from the peculiar environment of a less technologically developed country. The role of Government policies is of particular importance.
