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
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
DIVERTICULOSIS IN AMBULATORY PATIENT
Get PDFThe aim of this study was to observe the clinical presentation and to descibe same clinical, endoscopic and prognosis aspects for outgoing patients with diverticulosis from Argeş area.
Material and method. 192 patients were included in this study, with no prior medical records attesting the
presence of diverticulosis. The study was conducted between 2011 and 2015 in ambulatory setting. Medical
history, clinical exam and colonoscopy were undertaken during the visit. Inclusion criteria was the diagnosis of
diverticulosis.
Results. Colonoscopy was the method of investigation for confirmation of diverticulosis. Sex distribution was
almost equal, for diverticulitis the sex ratio was raised towards female sex. Most patients were asymptomatic and from urban environment. Hemorrhoids were the cause for most of the hematochezia cases, only one case of diverticular bleeding.
Discussions. the outgoing patients have mild symptoms and good clinical status compared to those needing
hospitalisation. Differential diagnosis with irritable bowel syndrome needs a careful anamnesis.
Conclusions. Frequent location of the diverticula was in the sigmoid and descending colon. Most patients have
no symptoms and the number is slightly smaller compared with other studies, but they represent the majority in the analysed group. Most of the diverticulitis patients were older than 66 and females. There is an association between diverticular disease and irritable bowel syndrom
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
Colonic Diverticulosis: From Asymptomatic Form to Major Complications
No full textAbstract
Introduction This pathology is rare in patients younger than 40 years old (5%) and, in those older than 70 years old, almost 50% exhibit colonic diverticulosis. Most cases have mild symptoms and only 20% presents complications as: bleeding, bowel obstruction, abscess and secondary peritonitis.
Aim. The aim is to analyse different types of complications in colonic diverticulosis and compare the data from literature to those in Argeș geographical area.
Material and method. The medical records of 120 patients out of which 101 were admitted in gastroenterology department and 19 in general surgery department were analysed. Diagnosis methods: colonoscopy, computed tomography with contrast dye, simple abdominal radiograph for acute abdominal pain.
Results. 40 patients (33.33%) with asymptomatic colonic diverticulosis, 28 patients (23.33%) moderate diverticulitis, 25 patients (20.83%) with moderate anorectal bleeding, 25 patients (20.83%) with secondary peritonitis, and 2 (1.68%) cases with complications.
Conclusions. All the patients were older than 50 years old, 44 % of diverticulitis cases led to complications (almost half with bleeding and the rest with peritonitis). No bowel obstruction. In 99% of the cases, the localisation of the diverticula was at the level of sigmoid and descending colon.
