No full textLetter by toscano et al regarding article. association of leukoaraiosis with convalescent rehabilitation outcome in patients with ischemic stroke
Full text linkGiven the aforementioned link between leukoaraiosis and swallowing impairment, and the burden of poststroke dysphagia on rehabilitation outcome, it could be of some interest to analyze the relationships between leukoaraiosis, recovery, and dysphagia in your large population
Commentary: Early Screening Parameters for Dysphagia in Acute Ischemic Stroke
Full text linkWe read with great interest the article by Henke et al. (1) aimed to identify early assessable predictors of dysphagia in the acute phase of ischemic stroke. A multivariate logistic regression analysis revealed higher age, male gender, and higher stroke severity [as assessed by NIH stroke scale (NIHSS)] to be independent predictor of poststroke dysphagia. Moreover, ROC analysis showed that in the acute phase of stroke NIHSS score of 4.5 was the best cut-off between dysphagic and non-dysphagic patients.
This research field certainly has a remarkable clinical interest, because it may lead to individuate those acute stroke patients who may benefit from a more detailed assessment of their swallow function (i.e., using fiberoptic endoscopic evaluation of swallowing or videofluoroscopy). However, an NIHSS cut-off for dysphagia of 4.5, by excluding only stroke patients with a very mild deficit, is probably of limited clinical usefulness. In other words, since the majority of stroke is of moderate-severe degree, it appears to be of little help in detecting only those patients who may benefit from a more detailed assessment of their swallowing function
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
