Focal motor seizure with automatisms in a newborn
No full textContinuous synchronized video-EEG-polygraphic recordings allow us to better define the electroclinical patterns of epileptic events and to study the semiological features of neonatal seizures. Recently, complex behaviours and motor automatisms in newborns have been reported as being epileptic in nature. However, the debate on physiopathology (cortical or brainstem release phenomena) is ongoing. We present the synchronized video-EEG documentation of epileptic complex motor behaviours in a newborn male. Our case contributes to the discussion regarding the serniological classification of the neonatal seizures
Children with convulsive epileptic seizures presenting to padua pediatric emergency department: The first retrospective population-based descriptive study in an Italian health district
No full textConvulsive epileptic seizures in children represent a common cause of admission to pediatric emergency department. Data about incidence, etiology, and outcome are still lacking in literature. We retrospectively reviewed medical records of children presenting to our pediatric emergency department with convulsive seizures during a 12-month period and collected their diagnoses over the following year. In all, 182 children met the inclusion criteria, for a total of 214 visits (1.2% of all attendances, n = 24 864). Seizures lasted less than 5 minutes in 76%, 5 to 30 minutes in 20%, 30 to 60 minutes in 2%, and over 60 minutes in 2% visits ("early," "established," "refractory," convulsive status epilepticus, respectively). Incidence of "early" (seizure lasting 5-30 minutes) and "established" (seizure lasting 30-60 minutes) status epilepticus was 52/100 000/year and 7/100 000/year respectively. Most common causes were febrile seizures (56%) and remote symptomatic seizures (19%). Knowing the epidemiology of convulsive seizures in children is important to guide appropriate management and individualized follow-up
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
