Going Beyond Counting First Authors in Author Co-citation Analysis
Get PDFThe 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
Development, implementation, and evaluation of self-regulated learning program in physical education
No full textThe aim of the dissertation was the examination of self-regulated learning inelementary physical education. A social cognitive perspective of self-regulatedlearning was adopted for the design of five studies which examined the effectivenessof various self-regulatory processes. Participants in the five studies were 380 fifth andsixth grade students (168 boys, 212 girls) from 10 elementary schools. Amicroanalytic methodology was adopted and students participated in the studiesindividually, in pairs, or in small groups. Generally, the results showed that fifth andsixth grade students effectively used self-regulatory processes to enhance the learningof motor and sport skills in physical education. In particular, in the first study,students who practiced dart-throwing with social feedback and then with processgoals and self-recording displayed the highest performance, supporting theeffectiveness of the social cognitive model of self-regulated learning. The results ofthe second study showed a positive effect of self-recording on students’ dart-throwingperformance, while no difference among the different goal conditions (process,performance, combined goals) was found. The results of the third study showed thatself-talk had a positive effect οn students’ dart-throwing performance during goaldirectedpractice, supporting the hypothesis of the self-talk incorporation into thecyclical model of self-regulated learning. The results of the fourth study showed thatself-talk had a positive effect on performance. Instructional and motivational self-talkwere equally effective in the chest pass task, whereas motivational self-talk was moreeffective compared to instructional self-talk in the modified push-ups task, providingpartial support for the task-demand-oriented matching hypothesis. The results of thefifth study showed that the use of the reciprocal and the self-check styles had apositive effect on students’ chest pass accuracy and technique. Students’ recordingaccuracy in the reciprocal and self-check styles was moderate with a tendency tooverestimation of performance. In conclusion, the use of self-regulatory processes can enhance students’ learning and performance of motor and sport skills in elementaryphysical education. The social cognitive perspective is an appropriate framework forstudying self-regulated learning in physical education. Based on this approach and theresults of the present studies an instructional approach for teaching motor and sportskills in physical education was proposed. This approach includes instructions,modeling, practice with social feedback and self-directed practice with goals and selfmonitoring.Σκοπός της διατριβής ήταν η μελέτη της αυτο-ρύθμισης της μάθησης αθλητικών καικινητικών δεξιοτήτων στη φυσική αγωγή στο δημοτικό. Ως θεωρητικό πλαίσιοχρησιμοποιήθηκε η κοινωνική γνωστική προσέγγιση αυτο-ρύθμισης της μάθησης, γιανα σχεδιαστούν πέντε έρευνες που εξέτασαν την αποτελεσματικότητα επιμέρουςδιαδικασιών αυτο-ρύθμισης. Συνολικά συμμετείχαν 380 μαθητές/τριες Ε΄ και Στ΄τάξης (168 αγόρια, 212 κορίτσια) 10 δημοτικών σχολείων. Χρησιμοποιήθηκε κυρίωςη μικροαναλυτική μέθοδος και οι μαθητές/τριες συμμετείχαν στις έρευνες ατομικά,σε ζευγάρια ή σε μικρές ομάδες. Από τα αποτελέσματα των ερευνών φάνηκε ότι οιμαθητές/τριες δημοτικού ήταν σε θέση να χρησιμοποιήσουν αποτελεσματικάδιαδικασίες αυτο-ρύθμισης και να ενισχύσουν τη μάθηση αθλητικών και κινητικώνδεξιοτήτων στη φυσική αγωγή. Πιο συγκεκριμένα, στην πρώτη έρευνα βρέθηκε ότι οιμαθητές/τριες που ασκήθηκαν στην αρχή με κοινωνική ανατροφοδότηση και στησυνέχεια με στόχους διαδικασίας και αυτο-καταγραφή είχαν την υψηλότερη επίδοσηστη ρίψη βέλους, υποστηρίζοντας την αποτελεσματικότητα του κοινωνικούγνωστικού μοντέλου των τεσσάρων επιπέδων ανάπτυξης της αυτο-ρύθμισης τηςμάθησης. Στη δεύτερη έρευνα βρέθηκε θετική επίδραση της αυτο-καταγραφής στηναπόδοση των μαθητών/τριών στη ρίψη βέλους, ενώ δεν βρέθηκαν διαφορές μεταξύτων μαθητών/τριών που έθεσαν διαφορετικού τύπου στόχους (στόχο διαδικασίας,απόδοσης, συνδυασμό στόχων διαδικασίας και απόδοσης). Στην τρίτη έρευναβρέθηκε ότι η χρήση της αυτο-ομιλίας στη διάρκεια στοχοκατευθυνόμενηςεξάσκησης είχε θετική επίδραση στην απόδοση των μαθητών/τριών στη ρίψη βέλους,υποστηρίζοντας την υπόθεση της εισαγωγής της αυτο-ομιλίας στη φάση απόδοσηςτου κυκλικού μοντέλου αυτο-ρύθμισης της μάθησης. Στην τέταρτη έρευνα βρέθηκεότι η αυτο-ομιλία είχε θετική επίδραση στην απόδοση. Η τεχνική και η παρακινητικήαυτο-ομιλία ήταν εξίσου αποτελεσματικές στην πάσα στήθους, ενώ η παρακινητικήαυτο-ομιλία ήταν πιο αποτελεσματική σε σύγκριση με την τεχνική στις τροποποιημένες κάμψεις, υποστηρίζοντας μερικά την υπόθεση ταιριάσματος τηςαυτο-ομιλίας με τις απαιτήσεις της δεξιότητας. Στην πέμπτη έρευνα βρέθηκε ότι τοαμοιβαίο στυλ και το στυλ αυτο-ελέγχου είχαν θετική επίδραση στην απόδοση τωνμαθητών/τριών στην ακρίβεια και στην τεχνική της πάσας στήθους. Η ακρίβειακαταγραφής της απόδοσης των συμμαθητών/τριών με το αμοιβαίο στυλ και της αυτο-καταγραφής με το στυλ αυτο-ελέγχου κυμάνθηκε σε μέτρια επίπεδα με τάσειςυπερεκτίμησης της απόδοσης. Συμπερασματικά, η χρήση διαδικασιών αυτο-ρύθμισηςμπορεί να ενισχύσει τη μάθηση αθλητικών και κινητικών δεξιοτήτων στη φυσικήαγωγή στο δημοτικό. Η κοινωνική γνωστική προσέγγιση αυτο-ρύθμισης της μάθησηςαποτελεί κατάλληλο θεωρητικό πλαίσιο για τη μελέτη της αυτο-ρύθμισης τηςμάθησης στη φυσική αγωγή. Με βάση την προσέγγιση αυτή και τα αποτελέσματατων ερευνών της διατριβής προτείνεται ότι η διδασκαλία αθλητικών και κινητικώνδεξιοτήτων στη φυσική αγωγή πρέπει να περιλαμβάνει διαδοχικά σύντομεςπροφορικές οδηγίες εκτέλεσης της δεξιότητας, την επίδειξή της, την άσκηση μεανατροφοδότηση και την αυτοκατευθυνόμενη άσκηση με στόχους και αυτο-παρακολούθηση
The effects of cognitively challenging physical activity games versus health-related fitness activities on students’ executive functions and situational interest in physical education: a group-randomized controlled trial
No full textThis study compared cognitively challenging physical activity games and health-related
fitness activities in terms of their effects on students’ executive functions and situational interest in
physical education. A total of 102 fourth- and fifth-grade students (56 boys, 46 girls) participated
in this study. A group-randomized controlled trial design involving an acute experiment was used.
Two intact classes of students (one fourth-grade and one fifth-grade) were randomly assigned to each
one of the three groups. Students in Group 1 participated in cognitively challenging physical activity
games, students in Group 2 participated in activities for developing their health-related fitness, and
Group 3 students were the control group without physical education. Executive functions were
measured pre- and post-intervention with the design fluency test, whereas situational interest was
only measured post-intervention with the situational interest scale. Group 1 students who played
cognitively challenging physical activity games had increased their executive functions’ scores more
than the Group 2 students involved in health-related fitness activities. Students of both these groups
outperformed control group students. Moreover, Group 1 students reported higher levels of instant
enjoyment and total interest than Group 2 students. The results of this study suggest that cognitively
challenging physical activity games can be an effective means for enhancing executive functions, and
motivate students to be involved in interesting and enjoyable forms of physical activity
Variations on the Author
Get PDF“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
Get PDFWe 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
Get PDFWe 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 textWe 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
