Socio-economic mobility in Greece and the role of education
No full textThe aim of this study is to investigate the social mobility in Greece over time (going back in the past as far as reliable data sources allow) and to what extent different approaches of social mobility were affected by education. The major research questions are to examine the data of income, occupation and education in Greece in order to measure the social mobility during a long-run period and the impact of the recent financial crisis. In addition, there is intention to explore whether social mobility follows specific patterns with these dimensions and determine the barriers to social mobility as well as the significance of educational background (establish a causal relationship between the indicators and education) Finally, to draw useful conclusions that can be used for policymakers to increase social mobility, in particular by understanding the role of education correctly (the policy responses in education to tackle social mobility’s challenges). The thesis is divided in three chapters. Each subchapter tries to answer additional research questions that occurred by each dimension and existing research/literature. The proposed research methodology involves secondary data analysis (descriptive and inferential statistics), microdata analysis with econometric methods, quantitative investigation through a questionnaire survey. To our knowledge, very limited empirical research has been carried out regarding all the aspects of social mobility in Greece. This is the main contribution of this thesis.Greek Ministry of Educatio
Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
The influence of education on social mobility in Croatia and Greece: a comparative analysis
No full textThis paper explores social mobility in Greece and Croatia among individuals born between 1950-2000, focusing on the role of education in occupational and educational mobility. We draw information on both dimensions from the European Union Statistics on Income and Living Conditions (EU-SILC) survey. When intergenerational educational mobility is examined our findings show a downward trend of upward mobility with the outcomes being better for women in both countries. They also suggest that individuals whose parents have a low level of education are significantly less likely to complete tertiary education than those whose parents have higher levels of education. Exploring intergenerational occupational mobility as an indicator of relative mobility reveals a growing persistence of the influence of parental occupational status on children’s outcomes. Although the influence of education is slightly stronger in Greece, higher educational levels increase the probability of upward occupational mobility in both countries
Η κοινωνικοοικονομική κινητικότητα στην Ελλάδα και ο ρόλος της εκπαίδευσης

Τα κύρια ερευνητικά ερωτήματα είναι να εξεταστούν τα δεδομένα εισοδήματος, επαγγέλματος και εκπαίδευσης στην Ελλάδα προκειμένου να μετρηθεί η κοινωνική κινητικότητα σε μια μακροχρόνια περίοδο και ο αντίκτυπος της πρόσφατης οικονομικής κρίσης. Επιπλέον, να διερευνηθεί εάν η κοινωνική κινητικότητα ακολουθεί συγκεκριμένα πρότυπα σε διαφορετικές διαστάσεις και να προσδιοριστούν τα εμπόδια στην κοινωνική κινητικότητα καθώς και η σημασία του μορφωτικού υποβάθρου (δημιουργία αιτιώδους σχέσης μεταξύ των δεικτών και της εκπαίδευσης). Τέλος, να εξαχθούν χρήσιμα συμπεράσματα που να μπορούν να χρησιμοποιηθούν από τους υπεύθυνους χάραξης πολιτικής για την αύξηση της κοινωνικής κινητικότητας, ιδίως με την σωστή κατανόηση του ρόλου της εκπαίδευσης. Η διατριβή χωρίζεται σε τρία κεφάλαια. Κάθε υποκεφάλαιο προσπαθεί να απαντήσει σε πρόσθετα ερευνητικά ερωτήματα που προέκυψαν από την κάθε διάσταση και την υπάρχουσα έρευνα/βιβλιογραφία. Η προτεινόμενη ερευνητική μεθοδολογία περιλαμβάνει δευτερογενή ανάλυση δεδομένων (περιγραφική και συμπερασματική στατιστική), ανάλυση μικροδεδομένων με οικονομετρικές μεθόδους, ποσοτική διερεύνηση μέσω έρευνας ερωτηματολογίου. Από όσο γνωρίζουμε, έχει διεξαχθεί πολύ περιορισμένη εμπειρική έρευνα σχετικά με όλες τις πτυχές της κοινωνικής κινητικότητας στην Ελλάδα. Αυτή είναι η κύρια συμβολή της παρούσας διπλωματικής εργασίας
Variations on the Author
Full text link“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
Appropriate Similarity Measures for Author Cocitation Analysis
Full text linkWe provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis
Dispelling the Myths Behind First-author Citation Counts
Full text linkWe conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods
Intragenerational occupational mobility: the effect of crisis and overeducation on career mobility in a segmented labour market
Full text linkopen access articleThis paper explores occupational and employment mobility over the previous decade in Greece and contributes to a better understanding of the consequences of the crisis. Our findings suggest that downward mobility was the common trend in intra-generational occupational mobility during the first period of the crisis. Significant changes occurred between 2011-2015. The recovery is apparent during the third bailout program with higher upward occupational and employment movements. However, polarization in the middle-paid professions was noticed. In addition, this paper highlights the role of education in career mobility and the problem of overeducation. The empirical results reveal that tertiary graduates were more likely to move downward during the first period of the crisis even though overeducated workers had more possibilities to experience upward mobility. Overeducation in Greece seems to be the result of the increasing number of tertiary graduates, low proportion of high-skilled job positions and high levels of unemployment
