Cardiac asystoles misdiagnosed as epileptic seizures
No full textWe report a case of a 78-year-old man who presented several episodes of transient loss of consciousness preceded by sensation of ascending heat from the feet, with increasing frequency and duration within a few weeks. One month later he was admitted because he started to fall during the episodes, which became daily. Brain MRI detected a gliotic right frontal area, and EEG showed slow activity in the same region. Carbamazepine was started without clinical response despite high plasmatic level. Video-EEG polygraphic monitoring was performed and the patient showed an episode of left hemifacial clonic jerks followed by loss of consciousness, starting 17 s after the beginning of asystole. Synus rhythm reappeared 32 s later and the patient regained consciousness in few seconds. A pacemaker was implanted and carbamazepine was withdrawn. No further episodes occurred
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
