Going Beyond Counting First Authors in Author Co-citation Analysis
Get PDFThe 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
Get PDF“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
Get PDFWe 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
Acufene pulsante associato a bulbo della giugulare alto omolaterale ed aplasia dei seni trasverso e sigmoide controlaterali.
No full textPulsating tinnitus is uncommon in the general population. This clinical manifestation can be associated with severe intracranial pathologies and is particularly characterized by a rhythm and synchronism reflecting the heart beat. This work presents a clinical case of pulsating, subjective tinnitus associated with a high homolateral jugular bulb and marked hypoplasia of the contralateral transverse and sigmoid sinuses and the clinical-radiological examinations that made diagnosis possible (particular reference going to CT, MRI and angio-MRI). The intracranial venous drainage pattern varies and is nearly always asymmetrical. The jugular bulb is defined as "high" when its upper edge extends nearly to the level of the tympanic anulus, a condition found in 6-20% of the general population. In many cases it is found by chance as often this condition is asymptomatic. However, the pathological picture associated with pulsating tinnitus is highly complex and requires a detailed diagnostic process which some Authors have arranged in specific "flow charts". Imaging methods are essential and must be identified according to the clinical-audiological findings. The radiologist can avail himself of CT, MRI (in association with angio-MRI), Doppler ultrasound of the supraortic and transcranial branches, and digital imaging subtraction angiography. The therapeutic approach to the patient manifesting a "high" jugular bulb is surgical and makes use of such procedures as: ligature of the internal jugular vein, extracranial transposition of the bulb and, in cases of dehiscence of the limiting bone, hypotympanum repair using an autologous or homologous graft of cartilage or bone. Whichever the case, an accurate cost-benefit evaluation must be made, particularly in regard to the risks of endocranial hypertension from the reduced venous drainage, a condition which is significantly increased when concomitant abnormalities of the dural sinuses are present. In the present case, this risk was quite high because of the particular venous morphology described and the patient refused surgery. Currently the patient is under clinical-radiological observation
Dispelling the Myths Behind First-author Citation Counts
Get PDFWe 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
koamabayili/VECTRON-author-checklist: VECTRON author checklist
No full textWe have done our best to complete the author checklist relating to the use of animals in the hut study. Note that the objective for the hut study was to evaluate the IRS treatment applications for residual efficacy against Anopheles mosquitoes, including the local An. coluzzii mosquito population. Cows were only used to attract mosquitoes into the huts and no tests were carried out directly on the cows. The author checklist is intended for use with studies where experiments are carried out on animals, which is why we have had such difficulty in completing this for the hut study, as many of the questions do not relate to how the cows were used
