No full textThe association between IUD use and the occurrence of pelvic infections caused by actinomyces was investigated in 221 IUD users at a University of Turin clinic. Pelvic actinomycosis is chronic and progressive, and diagnostic error and/or inappropriate treatment often lead symptoms to persist for years. Each study participant had a Papanicolaou smear both before IUD insertion and during IUD use. No Pap smear was positive for actinomyces before IUD insertion; however, during IUD use, this microorganism was identified in 30 patients (14\%). There was no correlation between infection and socioeconomic status, a history of prior abortion, or IUD size. There was no significant difference between infection rates in nulliparae (12\%) and primiparae (14\%). Infection was found in 8\% of Papanicolaou class I patients and in 15\% of class II subjects. The mean duration of IUD use in women with positive Actinomyces vaginal smears was 32.1 months compared with 23.2 months for patients with negative findings. Finally, the risk of infection was higher among acceptors of plastic rather than copper IUDs. These findings confirm the association between IUD use and pelvic actinomycosis; a review of the literature reveals 395 such cases. When actinomycotic infection is discovered, immediate removal of the IUD is necessary and targetted antibiotic treatment should be commenced
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
Appropriate Similarity Measures for Author Cocitation Analysis
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
