    Going Beyond Counting First Authors in Author Co-citation Analysis

    Full text link
    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

    “Sign Language Interpretation: a newcomer to Italian university studies”

    No full text
    In Italy, in recent years, interest in sign language interpretation has gradually gained ground. Some twenty years ago, it was a skill performed by only a small number of people related in some way to a Deaf person or working within the Deaf community. Since the 1980s, Italian research on deafness and the complexities of sign language have led to more awareness of the needs of the Deaf among hearers and conversely, the Deaf themselves have started to take a more ac-tive role in the diffusion of Deaf culture outside the confines of their associations and clubs. Long-dated experience gained from professional interpreting prac-tice, from the training of students in consecutive and simultaneous in-terpretation and from direct participation in the recent sign language course, has enabled the authors to make interesting comparisons be-tween spoken and signed-language interpretation. The paper thus out-lines some of the salient differences and similarities existing between the better-known modes of oral language interpreting (simultaneous and consecutive) and interpretation from and into a signed language. Reference is also made to research work conducted at the SSLMIT on some features of sign language interpreting, such as the different strategies adopted in interpreting between signed languages, from speech-to-sign and from sign-to-speech, and the role of short-term memory in voice and sign interpreting

    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

    Full text link
    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
