    Going Beyond Counting First Authors in Author Co-citation Analysis

    Full text link
    The 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

    Βιβλιογραφία: σ. 72-76Η ραγδαία εξέλιξη της τεχνολογίας είναι πλέον μία πραγματικότητα, δεν θα μπορούσε να μην είναι ένα αναπόσπαστο κομμάτι στον εκπαιδευτικό χώρο. Η παρούσα μεταπτυχιακή εργασία διερευνά τη χρήση των διαδραστικών πινάκων στη δευτεροβάθμια εκπαίδευση και τον ρόλο τους στη διδακτική πράξη, μέσα από τις απόψεις και τις εμπειρίες των εκπαιδευτικών. Στόχος της μελέτης είναι να αποτυπώσει τους τρόπους αξιοποίησης των διαδραστικών πινάκων, τα παιδαγωγικά και οργανωτικά οφέλη που προκύπτουν από τη χρήση τους, καθώς και τις δυσκολίες και προκλήσεις που αναδεικνύονται στην καθημερινή σχολική πρακτική. Η έρευνα βασίστηκε σε ποιοτική μεθοδολογία και πραγματοποιήθηκε μέσω ημιδομημένων συνεντεύξεων με εν ενεργεία εκπαιδευτικούς της δευτεροβάθμιας εκπαίδευσης διαφορετικών ειδικοτήτων. Από την ανάλυση των δεδομένων προέκυψε ότι οι διαδραστικοί πίνακες αξιοποιούνται κυρίως για την προβολή του ψηφιακού σχολικού βιβλίου, τη χρήση εκπαιδευτικού λογισμικού, την προβολή βίντεο και προσομοιώσεων, καθώς και για την οργάνωση και αποθήκευση του διδακτικού υλικού. Παράλληλα, διαπιστώθηκε ότι ο τρόπος χρήσης τους διαφοροποιείται ανάλογα με την ειδικότητα του εκπαιδευτικού και το γνωστικό αντικείμενο. Τα ευρήματα ανέδειξαν σημαντικά οφέλη, όπως η εξοικονόμηση διδακτικού χρόνου, η καλύτερη οργάνωση της διδασκαλίας, η ενίσχυση της ενεργού συμμετοχής των μαθητών και η υποστήριξη της κατανόησης σύνθετων εννοιών μέσω οπτικοποίησης. Ωστόσο, καταγράφηκαν και ορισμένες αρνητικές επιδράσεις, όπως η διάσπαση της προσοχής των μαθητών, η εμφάνιση τεχνικών προβλημάτων και η έλλειψη επαρκούς επιμόρφωσης ορισμένων εκπαιδευτικών. Συνολικά, τα αποτελέσματα καταδεικνύουν ότι οι διαδραστικοί πίνακες αποτελούν ένα σημαντικό παιδαγωγικό εργαλείο, η αποτελεσματικότητα του οποίου εξαρτάται από τον τρόπο ενσωμάτωσής του στη διδακτική διαδικασία και από την παιδαγωγική και τεχνολογική ετοιμότητα των εκπαιδευτικών.The rapid development of technology is now an established reality and could not remain absent from the educational context. This postgraduate thesis investigates the use of interactive whiteboards in secondary education and their role in teaching practice, drawing on teachers’ perceptions and experiences. The aim of the study is to identify the ways in which interactive whiteboards are utilized, the pedagogical and organizational benefits arising from their use, as well as the difficulties and challenges encountered in everyday school practice. The research was based on a qualitative methodology and was conducted through semi-structured interviews with in-service secondary education teachers from different subject specializations. Data analysis revealed that interactive whiteboards are mainly used for displaying the digital school textbook, employing educational software, presenting videos and simulations, and organizing and storing teaching material. At the same time, it was found that the manner of their use varies depending on the teacher’s specialization and the subject matter taught. The findings highlighted significant benefits, such as the saving of instructional time, improved organization of teaching, enhanced active student participation, and support for the understanding of complex concepts through visualization. However, certain negative effects were also recorded, including students’ distraction, the occurrence of technical problems, and the lack of adequate training for some teachers. Overall, the results indicate that interactive whiteboards constitute an important pedagogical tool, whose effectiveness depends on the way they are integrated into the teaching process and on teachers’ pedagogical and technological readiness.78 σ

    Variations on the Author

    “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 link
    We 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 link
    We 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

    koamabayili/VECTRON-author-checklist: VECTRON author checklist

    No full text
    We have done our best to complete the author checklist relating to the use of animals in the hut study. Note that the objective for the hut study was to evaluate the IRS treatment applications for residual efficacy against Anopheles mosquitoes, including the local An. coluzzii mosquito population. Cows were only used to attract mosquitoes into the huts and no tests were carried out directly on the cows. The author checklist is intended for use with studies where experiments are carried out on animals, which is why we have had such difficulty in completing this for the hut study, as many of the questions do not relate to how the cows were used
