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
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

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
Pubertal Development in Pediatric Kidney Transplant Patients Receiving Mammalian Target of Rapamycin Inhibitors or Conventional Immunosuppression
No full textBackground. Data regarding the onset of puberty in children receiving mammalian target of rapamycin (mTOR) inhibitors are limited. Methods. Kidney transplant patients aged <14 years were analyzed retrospectively to a maximum age of 18 years, with a minimal observation period of 1 year. Immunosuppression comprised (1) standard CNI-based regimen or (2) low-exposure mTOR inhibitor with reduced-exposure CNI, initiated either de novo or in the maintenance phase. Results. Of 108 children analyzed, 67 received an mTOR inhibitor (56 everolimus, 11 sirolimus) and 41 did not. The age at which girls reached Tanner stage P2 was similar with mTOR inhibitor therapy (median 11.6 years) or without (median 11.1 years) (P = 0.262), as was age at stage B2 (median 11.6 vs. 11.2 years; P = 0.753). In boys, both the age of attaining Tanner stage P2 (median 12.9 vs. 13.0 years; P = 0.796) and Tanner stage G2 (median 13.1 vs. 12.9 years; P = 0.344) were also similar with or without an mTOR inhibitor. Age at menarche in girls, and age at spermarche in boys, did not differ between the 2 groups. Conclusions. In this retrospective analysis, sexual maturation ages and reproductive hormone levels were comparable in adolescent kidney transplant patients receiving low-exposure mTOR inhibitors and reduced CNI therapy or conventional CNI-based immunosuppression
