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
Greece’s new emigration at times of crisis
Full text linkAlthough considerable research is being carried out on the phenomenon of immigration to Greece, there is a notable lack of scientific attention on the recent resurgence of emigration at times of recession and austerity. Aiming to partly fill in this gap, this paper contextualizes the recent resurgence of emigration within Greece’s changing and complexifying migratory landscape. In so doing, and drawing on quantitative and qualitative data, the paper describes the magnitude, dynamics and main destinations of the current crisis-driven emigration and outlines its demographics makeup. It further provides evidence on the multiplicity of migration trajectories and discusses the prospect of return and the potential of the development of transnational economic ties between Greece and its highly skilled emigrants
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
"Knowledge Bridges / Cooperation Bridges": proposal for a cooperation network of Greek graduates living abroad with Greece
No full textΣήμερα αναγνωρίζεται ευρύτατα η μεγάλη σημασία του ανθρώπινου κεφαλαίου για την ανάπτυξη των χωρών. Το ενδιαφέρον των οικονομολόγων για το ανθρώπινο κεφάλαιο αναθερμάνθηκε κατά τη δεκαετία του ’50, μετά την αναγνώριση, από σημαντικούς οικονομολόγους, του γεγονότος ότι τα μοντέλα των θεωριών ανάπτυξης δεν μπορούσαν να ερμηνεύσουν περισσότερο από το μισό της αύξησης της παραγωγικότητας των σύγχρονων οικονομιών (γνωστή και ως «παράδοξο του Solow»). Μάλιστα, οι δύο τελευταίες δεκαετίες χαρακτηρίστηκαν από την ευρεία αναγνώριση της σημασίας της γνώσης, της καινοτομίας και του ανθρώπινου δυναμικού στην οικονομική ανάπτυξη, ιδίως όσον αφορά τις οικονομίες των αναπτυγμένων χωρών.Today the great importance of human capital for the development of countries is widely recognized. The interest of economists in human capital was rekindled during the 1950s, after the recognition, by important economists, of the fact that the models of development theories could not explain more than half of the productivity growth of modern economies (also known as the "Solow paradox"). Indeed, the last two decades have been characterized by the widespread recognition of the importance of knowledge, innovation and human resources in economic development, particularly regarding the economies of developed countries
From spectator to walk-on to actor: an exploratory study of the internationalisation of Greek firms since 1989
No full textThe article follows the evolution of the Greek business activities in foreign countries. Based on two unique databases, the article acknowledges the existence of two sub-periods. More particularly, the years up to 1998 are characterized by two central elements, whose importance diminishes during the second period: the overwhelming significance of the Balkans (especially the countries bordering on Greece) and the hesitance of large Greek firms. In the second period, large firms make a dynamic entry, while some of them start behaving as real TNCs. However, the importance of small firms but also of the Balkans is preserved. As anticipated, with the shift of the morphological features of Greek entrepreneurial activity in foreign countries, the impact on the Greek economy also changes
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
Brain drain and the Greek crisis
Full text linkIn the context of the debt crisis, recession, austerity and their socio-political consequences, Greece is experiencing a new major wave of out-migration. Emigration has become a survival strategy for many people who are finding it hard to make ends meet, while, at the same time, it has also emerged as an increasingly appealing option for others in less pressing need, who see their chances of socioeconomic advancement severely reduced. One dimension of this multifaceted phenomenon concerns the emigration of graduates, which accounts for approximately two-thirds of the outflow
