    Going Beyond Counting First Authors in Author Co-citation Analysis

    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

    The parameters which are involved in sychronous teleconferences and which lead to effective learning using experimental techniques

    Distance learning is a structured set of means and procedures which provide the appropriate methodology so that students can define the place, time and pace of their study by themselves. The teleconference is used as a distance learning tool, in secondary and mainly in higher education and in adult education training as well, in the framework of educational applications and connection programmes between educational organisations. This research aims to investigate the parameters which are involved in sychronous teleconferences and which lead to effective learning using experimental techniques. Teleconferences were held in the framework of the ‘Educational Technology course of ASPETE. ASPETE provides concurrent technological and pedagogical education and training at tertiary level. Synchronous teleconference services are available to the members of educational staff of ASPETE.Στην εξ αποστάσεως εκπαίδευση, η μάθηση εξαρτάται σε μεγάλο βαθμό από την ικανότητα του εκπαιδευόμενου να κατευθύνει και να διαχειρίζεται τη μαθησιακή του διαδικασία, τόσο με τη δημιουργία κατάλληλων στόχων, όσο και με την υιοθέτηση χρήσιμων στρατηγικών για την επίτευξή τους. Η διεθνής και η εγχώρια βιβλιογραφία αναφέρουν πολλές περιπτώσεις εξ αποστάσεως προγραμμάτων επιμόρφωσης, κατάρτισης και σπουδών. Ωστόσο, απουσιάζει από τη βιβλιογραφία κάποια αντίστοιχη μελέτη για τους παράγοντες που επιδρούν είτε αρνητικά, είτε θετικά στις περιπτώσεις εξ αποστάσεως διδασκαλίας. Η εργασία καθιστά ενδιαφέρουσα την προοπτική καταγραφής και αξιολόγησης όλων των παραγόντων που αλληλεπιδρούν σε ένα περιβάλλον εξ αποστάσεως επιμόρφωσης των εκπαιδευτικών μέσω της τηλεδιάσκεψης. Στο περιβάλλον σύγχρονης τηλεδιάσκεψης ο ρόλος του εκπαιδευτή έχει κύριο στόχο την ανάπτυξη μεθοδολογίας και τη δημιουργία των κατάλληλων συνθηκών για τη διευκόλυνση και ενεργοποίηση των συμμετεχόντων, ώστε να επεξεργάζονται την πληροφορία που τους παρέχεται μέσα από ένα τέτοιο περιβάλλον με όσο το δυνατόν περισσότερο μαθησιακά ωφέλιμο τρόπο. Σκοπός της παρούσας διδακτορικής έρευνας είναι η διερεύνηση, ανάλυση και μελέτη των παραγόντων που επιδρούν και επηρεάζουν θετικά ή αρνητικά τη διαδικασία και την αποτελεσματικότητα της μάθησης στην εκπαίδευση με βιωματικές τεχνικές διδασκαλίας κατά τη χρήση σύγχρονης τηλεκπαίδευσης. Ως εργαλεία για τη συλλογή των δεδομένων χρησιμοποιήθηκαν η παρατήρηση, η δομημένη συνέντευξη και το ερωτηματολόγιο. Δηλαδή, για την πληρέστερη λήψη συμπερασμάτων ελήφθησαν υπόψη ποσοτικές και ποιοτικές τεχνικές. Ως δείγμα χρησιμοποιήθηκε ο απαιτούμενος για μια έγκυρη από πλευράς γενίκευσης των αποτελεσμάτων αριθμός επιμορφούμενων εκπαιδευτικών και εκπαιδευτών στα τμήματα εκπαίδευσης της ΑΣΠΑΙΤΕ

    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

    “Multitasking” and Its Impact on Students from Teachers’ Perspective

    Full text link
    The demanding pace of modern society pushes us to multitask in order to achieve maximum efficiency and effectiveness. A key open question is whether multitasking is effective? Numerous studies have demonstrated the effects of “multitasking” on a psychological, cognitive and socio-emotional level. The results showed that students who engage in multitasking more often while completing their schoolwork tend to have lower academic performance. In addition, it was shown that multitasking is positively correlated with increased procrastination

    MENTAL HEALTH STRATEGIES IN THE CONTEXT OF SOCIAL ADVERTISING

    Full text link
    Emotions arise through interaction with the social environment and influence interpersonal relationships. They differ across individuals and are influenced by situational factors and the prevailing social context. Emotions are conveyed through multiple channels of communication, including language, body posture, and gestures, all of which significantly influence interpersonal interactions. Companies promote their products through advertisements on social media, aiming to influence individuals’ emotions and behavior through consistent and repetitive messaging. The overarching aim of advertisements is to elicit emotional responses and guide individual behavior. At the same time, individuals’ preferences for particular advertising messages can reveal key aspects of their personality profiles and the emotion regulation strategies they employ. The purpose of the present study is to contribute to the ongoing scholarly discourse of recent years regarding young adults’ perceptions of others’ expectations, the emotion regulation strategies they adopt, and the extent of socially prescribed perfectionism they experience—examined through the lens of social advertising.  Article visualizations
