    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

    Parent and Peer Attachment and Psychosocial Adjustment of Chinese Immigrant Adolescents in Italy.

    ORRECTED P There is much interest in understanding acculturation processes of Asian immi- grants, because they represent one of the prominent immigrant populations in many European and non-European countries. However, knowledge about the relation of acculturation and attachment processes of these groups is still scarce. Most research in the field involves only parenting or adaptation outcomes of Asian immigrant groups primarily in the USA, Canada, and few European countries (Chen et al. 2011, 2012). Understanding acculturation outcomes in Chinese minority groups is a prominent venue of research as they represent one of the largest and fastest grow- ing immigrant groups in Europe. To the best of our knowledge, no study so far has investigated the role of attachment to parents and peers on adaptation outcomes of Chinese immigrant youth in Italy, who are a relatively recent immigrant group characterized by strong ethnic enclaves and cohesive community. Therefore, this chapter addresses the question of whether immigrant youth differ from their native Italian peers with respect to their attachment and adaptation outcomes. Specifically, we examine parent and peer attachment and psychological adjustment of youth of Chinese descent living in Italy

    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
