    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

    The clearings of authentic learning in mathematics.

    This study is a hermeneutical phenomenological qualitative investigation of authenticity in mathematics learning. In the applicable literature the uses of the words "authentic" and "authenticity" are found to be problematic. Heidegger's ideas on authenticity are employed to show the many shades of meaning for authenticity. Heuristic methodology was employed to describe the patterns of organization of the experience of authentic learning. Data sources include the researcher's field notes, observations, classroom conversations, student reflections, and student interviews. Descriptions of the experiences of authentic learning were produced using the reflective guidelines associated with heuristic research: initial engagement, immersion, incubation, illumination, explication, and creative synthesis.The themes found in this research where in strong relationship to one another and were explicated using Heideggerian terminology so as to show their distinctiveness without removing them from the context of the other themes. In the descriptions of the experience of authentic learning four interactive and interrelated themes presented themselves. These themes are called clearings, dynamic spaces where students reveal the patterns of organization for their learning. The four clearings were called: the clearings of mathematics, the clearings of relationship, the clearings of occupation, and the clearings of newness and wonder. The findings of the study make problematic the current use of the words "authentic" and "authenticity" as found in the literature. The findings were also found to relate to current research in curriculum theory. Researcher recommendations for teachers and educational reformers are presented as suggested by this research

    Dispelling the Myths Behind First-author Citation Counts

    Get PDF
    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
