    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

    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

    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

    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

    Hvordan fremme kritisk tenkning i grunnskolen? Forskningsbaserte forslag

    No full text
    Til tross for fokus på kritisk tenkning som en nødvendig ferdighet, er det få som har kommet med tiltak for hvordan lærere kan støtte utvikling av denne typen tenkning blant elever i den norske skolen. Vi tar et grep om denne utfordringen. Først foreslår vi et teoretisk rammeverk for å forstå sentrale deler innen kritisk tenkning. Deretter presenterer vi nyere forskning som fremmer forslag til hvordan kritisk tenkning kan stimuleres i grunnskolen. Vårt fokus er på argumentasjon, kildevurderingsferdigheter og kunnskapssyn. Basert på vår gjennomgang av relevant litteratur identifiserer vi implikasjoner for læreres praksis

    koamabayili/VECTRON-author-checklist: VECTRON author checklist

    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

    What happens when you push the button? Analyzing the functional dynamics of concept development in computer supported science inquiry

    No full text
    In this article we analyze how the joint cognitive system of teacher and student actions mediated by cultural tools develops sense making of science concepts, and the use of concepts as tools for explaining phenomena and processes related to energy and energy transformation. We take a sociocultural approach to the analysis of how material and digital learning resources become tools for thinking and reasoning. We combined ethnographic descriptions with analysis of video records of classroom interactions in a high school and examined how a teacher and a group of students engaged in a computer-supported collaborative inquiry. Our results show that students through inquiry are enabled to make sense of concepts and their experiences with resources and also to use science concepts as explanatory tools. However, this is mediated by the teachers’ practices for supporting students, such as providing relevant clues for them to continue their inquiry, eliciting their initial understanding of concepts thereby making them available for further development, pressing for explanations, and reformulating their explanations. The teacher is continuously alternating between withdrawing and making students inquire by themselves and supporting their inquiry. In and through such social interactions, materials and digital tools become tools for thinking. We argue that one of the practical implications of our study is that it is crucial that teachers explicitly draw students into their system of activity throughout the entire learning trajectory and that the teachers and students together make sense of science concepts for explaining energy transformation.
