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
Chronic axonal-demyelinating polyradicular neuropathy associated with mycosis fungoides: a case report
No full textCase of a 58-year-old patient diagnosed as having mycosis fungoides (MF) who presented with sensory ataxia, limbs weakness and neurophysiological and laboratory signs indicative of autoimmune chronic mixed axonal-demyelinating sensory-motor polyradicular neuropathy. The possibility that MF may be associated with an immunomediated peripheral neuropathy, even in the absence of a direct invasion of the nerves and widespread visceral involvement, should be considered
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
Influence of early high-dose steroid treatment on Bell's palsy evolution
No full textThe objective of this double-blind, randomized, placebo-controlled study was to test the efficacy of high-dose prednisone, administered as early as possible, in modifying the natural progression of Bell's palsy. Sixty-two consecutive patients, enrolled within 72 hours of facial palsy onset, were assigned to high dose intravenous prednisone in combination with intramuscular polyvitaminic therapy (group A) or polyvitaminic therapy alone (group B). Clinical grading of facial muscle strength and length of absence from work were evaluated. An early worsening of facial muscle strength was observed in controls, leading to the divergence in the trends of the grading scores in the two groups; this result was not confirmed in the long-term follow-up. Treated patients returned to work earlier than controls. In conclusion, early treatment based on high-dose corticosteroids slightly accelerates spontaneous improvement in Bell's palsy
