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
Assess the role of different methods in screening of tuberculosis in children
Full text linkCatedra Pneumoftiziologie USMF „Nicolae Testemiţanu”To determine the effectiveness of different methods of detecting TB in children were analyzed all cases of tuberculosis in children 0-14 years in Chisinau in two periods of time. The first period covered the years 1986 – 1990, when detection of tuberculosis in children based on mass tuberculinodiagnostics and second period covered the years 2004 - 2008, when the main method of detecting TB was examination patients presenting with symptoms suggestive of tuberculosis (“tuberculosis suspects”). It was established that the annual tuberculin testing is detected only 9, 3 ± 3,3% children with tuberculosis. It was found that during the years 2004 - 2008 most children were not take chemoprophylaxis – 79,9 ± 6,1%, p <0,001
Pentru aprecierea eficacităţii diferitor metode de depistare a tuberculozei la copii au fost analizate toate cazurile de tuberculoză la copii 0-14 ani din mun. Chişinău din 2 perioade de timp. Prima perioada a cuprins anii 1986 - 1990 când depistarea tuberculozei la copii se baza pe tuberculinodiagnostica în masă şi a doua perioada a cuprins anii 2004 – 2008, când principala metoda de depistarea a tuberculozei a fost examinarea simptomaticelor. S-a stabilit că prin testarea tuberculinică anuală se depistează numai 9,3±3,3% copii cu tuberculoză. S-a constatat că în perioada anilor 2004 – 2008 majoritatea copiilor nu au primit chimioprofilaxie - 79,9±6,1%, p<0,001
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
Tuberculosis in children
Full text linkCatedra Pneumoftiziologie USMF „Nicolae Testemiţanu”Tuberculosis is one of the major infections affecting children worldwide. It causes significant morbidity and mortality, especially in infants and young children. Diagnosis of tuberculosis in children is difficult and poses problems that are not present in adults. Children with tuberculosis respond well to and tolerate the same basic treatment regimens as used for adults. The best method to prevent cases of pediatric tuberculosis is to find, diagnose, and treat cases of active tuberculosis among adults. With BCG vaccination in neonatal period (even in infancy) can undoubtedly reduce serious forms of tuberculosis
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
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
