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 importance of teaching probability in school and factors that affect the teaching process
No full textProbability is one of the mathematics domains with the greatest usefulness in everyday life (Batanero et al., 2016). Their appeal in various sciences, such as meteorology, natural sciences, health sciences and economics, but also in situations where there is uncertainty or the need for a forecast, makes Probability a very interesting field of mathematics (Reia et al., 2019). This fact could not be unnoticed when designing mathematics curricula in most developing countries. As a result, many countries around the world have enriched their mathematics curriculum with the introduction of Probabilities (Batanero et al., 2016).Among these countries, Greece has developed a rich curriculum for Probability, which has been in effect since 2003. The country in its program, includes Probability in Primary and Secondary education, dividing the teaching objectives according to the age level of the students. In addition, the paper analyses the educational systems of Singapore and the Netherlands, as well as the role of Probabilities in them. The evolution of the curriculum, but also the teaching course of mathematics during a school year, often force the teacher to deviate from the given goals. Result, that affects the learning of the theory of Probability. In general, learning can be influenced by a variety of factors, but it is important to emphasize to five key factors influencing learning, with the goal of improving the learning process in Probability. More specifically, the relationship of students with mathematics, their perception of the probabilities, the readiness of the teacher to teach the specific domain of mathematics, school textbooks and various other social or cultural factors. The present work has multiple objectives, focusing on the study of the usefulness of Probabilities in daily procedures, the study of the extent of achievement of the instructions of the curricula and the improvement of the teaching books in the courses of Probabilities. For these needs, the research focused on a sample of 542 people of different majors for answering the questionnaire, 5 secondary school mathematics teachers who took part in an interview process and the comparative analysis of textbooks in the chapters of Stochastic mathematics in Greece, Singapore and the Netherlands. The results of the research show that there is a generally positive perception about the use of Probability theory in everyday activities and in fact most of the sample recognizes a direct relationship between Probability and decision making. Teachers find it difficult to follow the detailed instructions and hours suggested by the curriculum, with the result that the teaching of Probability deprives of the necessary time. Finally, the textbooks of the three countries studied, show many similarities, however there are several differences, many of which are considered quite important and affect the learning opportunities offered to the student.Οι Πιθανότητες είναι ο κλάδος των μαθηματικών με την μεγαλύτερη χρηστικότητα στην καθημερινή ζωή (Batanero et al., 2016). Η απήχηση τους σε διάφορες επιστήμες, όπως η μετεωρολογία, οι φυσικές επιστήμες, οι επιστήμες υγείας και η οικονομία, αλλά και σε καταστάσεις που υπάρχει αβεβαιότητα ή ανάγκη πρόβλεψης, καθιστούν τις Πιθανότητες ένα πολύ ενδιαφέρον κομμάτι των μαθηματικών (Reia et al., 2019). Το γεγονός αυτό δεν θα μπορούσε να περάσει απαρατήρητο κατά τον σχεδιασμό των προγραμμάτων σπουδών των μαθηματικών στις περισσότερες αναπτυσσόμενες χώρες. Κατά συνέπεια, πολλές χώρες ανά τον κόσμο εμπλούτισαν το πρόγραμμα σπουδών τους για τα μαθηματικά με την εισαγωγή των Πιθανοτήτων (Batanero et al., 2016). Μεταξύ των χωρών αυτών, η Ελλάδα διαμόρφωσε ένα πλούσιο πρόγραμμα σπουδών για τις Πιθανότητες, το οποίο βρίσκεται εν ενέργεια από το 2003 έως σήμερα. Η χώρα στο πρόγραμμα της, εντάσσει την Πιθανότητα στην Πρωτοβάθμια και την Δευτεροβάθμια εκπαίδευση, χωρίζοντας τους διδακτικούς στόχους ανάλογα την ηλικιακή βαθμίδα των μαθητών. Επιπροσθέτως, στην εργασία αναλύονται τα εκπαιδευτικά συστήματα της Σιγκαπούρης και της Ολλανδίας, καθώς και ο ρόλος των Πιθανοτήτων σε αυτά.Η εξέλιξη της διδακτέας ύλης, αλλά και η διδακτική πορεία των μαθηματικών κατά την διάρκεια ενός διδακτικού έτους, πολλές φορές αναγκάζουν τον εκπαιδευτικό να αποκλίνει από τους δεδομένους στόχους. Αποτέλεσμα που επηρεάζει την μάθηση της θεωρίας των Πιθανοτήτων. Γενικότερα η μάθηση μπορεί να επηρεαστεί από ποικίλους παράγοντες, ωστόσο σημαντικό είναι να δοθεί έμφαση στους πέντε βασικότερους παράγοντες επιρροής της μάθησης, με απώτερο σκοπό την βελτίωση της μαθησιακής διαδικασίας στις Πιθανότητες. Πιο συγκεκριμένα, της σχέσης των μαθητών με τα μαθηματικά, της αντίληψης τους για τις πιθανότητες, την ετοιμότητα του εκπαιδευτικού να διδάξει το συγκεκριμένο αντικείμενο των μαθηματικών, τα σχολικά εγχειρίδια και διάφορους άλλους κοινωνικούς ή πολιτισμικούς παράγοντες. Η παρούσα εργασία έχει πολλαπλούς στόχους, με επίκεντρο την μελέτη της χρησιμότητας των Πιθανοτήτων σε καθημερινές διαδικασίες, την μελέτη του βαθμού επίτευξης των οδηγιών των αναλυτικών προγραμμάτων και την βελτίωση των διδακτικών εγχειριδίων στα μαθήματα των Πιθανοτήτων. Για τις ανάγκες αυτές, η έρευνα επικεντρώθηκε σε ένα δείγμα 542 ατόμων διάφορων ειδικοτήτων για την απάντηση του ερωτηματολογίου, σε 5 εκπαιδευτικούς μαθηματικών δευτεροβάθμιας εκπαίδευσης που έλαβαν μέρος σε μια διαδικασία συνέντευξης και στην συγκριτική ανάλυση των σχολικών εγχειριδίων στα κεφάλαια των στοχαστικών μαθηματικών των χωρών Ελλάδα, Σιγκαπούρη και Ολλανδία. Τα αποτελέσματα της έρευνας δείχνουν, ότι υπάρχει γενικότερα μια θετική αντίληψη σχετικά με την χρήση της θεωρίας Πιθανοτήτων σε καθημερινές δραστηριότητες και μάλιστα αναγνωρίζεται από την πλειοψηφία του δείγματος μια άμεση σχέση των Πιθανοτήτων με την λήψη αποφάσεων. Οι εκπαιδευτικοί δυσκολεύονται να ακολουθήσουν τις αναλυτικές οδηγίες και τις ώρες που προτείνουν τα ΑΠΣ, με αποτέλεσμα η διδακτική των Πιθανοτήτων να στερείτε του αναγκαίου χρόνου. Τέλος, τα σχολικά βιβλία των τριών χωρών που μελετήθηκαν εμφανίζουν πολλές ομοιότητες, ωστόσο υπάρχουν και αρκετές διαφορές που πολλές από αυτές κρίνονται αρκετά σημαντικές και επηρεάζουν τις προσφερόμενες ευκαιρίες μάθησης στον μαθητή
Interdisciplinarity in Data Analysis Through the Primary School Textbooks in Greece and Singapore
Full text linkData analysis is one of the most popular fields of mathematics and includes statistics and probability. These two mathematical domains are some of the most well-known, influencing everyday life and the various sciences. Their teaching lays the foundation for primary education and culminates in secondary education. Probability and statistics are necessary for today and the future of several professions. This research attempts to highlight the multidisciplinary character of these two disciplines through the textbooks of primary education in Greece and Singapore. It aims to highlight the dependence of mathematics teaching on interdisciplinarity through textbooks. The textbook analysis was chosen because books offer varied learning opportunities. The researchers selected the books, partaking in the comparative analysis. After defining the basic principles dividing lines for the differentiation of the exercises, the analysis was conducted. It included two stages. In the first stage, the activities of the books were examined in their framework application. Then, their interdisciplinary character was accentuated in the scientific field. The results reveal a substantial dependence of data analysis on interdisciplinarity. More interesting is that the distribution of interdisciplinary exercises is prevalent in the scientific milieus
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
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
