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
Conservative management of left ventricle cardiac fibroma in an adult asymptomatic patient
No full textPrimary cardiac tumours are rare with an autopsy frequency of 0.001–0.03% and approximately 90% of them are benign. Among these, cardiac fibromas represent a minority and, together with rhabdomyomas, are the most common benign cardiac tumours in paediatric patients. However, their occurrence in the adult patient is uncommon. Most originate from the left ventricle (LV) or interventricular septum.
Patients with cardiac fibroma usually present with chest discomfort or pain, syncope, heart failure, cyanosis, arrhythmias or even sudden death but approximately one third of patients diagnosed with cardiac fibroma are asymptomatic and the tumour is discovered incidentally. There is a general agreement that surgical treatment should be performed whenever the cardiac fibroma is causing symptoms. In these patients, surgical options include complete surgical excision, partial resection or orthotopic heart transplantation. Indication for surgical treatment remains controversial in patients who are strictly asymptomatic. We report the case of an asymptomatic adult patient presenting with a giant LV cardiac fibroma and for whom we have opted for a conservative management. Conservative management of LV cardiac fibroma in an
adult patient who is strictly asymptomatic seems to be an acceptable strategy when the risks of complete surgical resection outweigh the benefits. Close clinical and instrumental follow-up is mandatory and the implantation of an ICD might be a reasonable precaution
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
Virtual collapse of true lumen in acute type A aortic dissection
No full textTrue lumen collapse may be a dynamic process. It predominates during diastole but is reduced during the ejection phase to allow distal true lumen perfusion. In our patient, the filling with contrast medium of both true and false lumens in the descending aorta supports this hypothesis
Dispelling the Myths Behind First-author Citation Counts
Full text linkWe conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods
