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

No full textVariations 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
Shoulder involvement in rheumatic diseases. Sonographic findings
Get PDFObjective. To distinguish using shoulder sonography the different changes present in rheumatoid arthritis (RA), polymyalgia rheumatica (PMR), and periarticular disorders (PD) of soft tissue of the shoulder. Methods. Ninety shoulders of patients with RA, 32 with PMR, 122 with PD, and 108 controls were studied sonographically, using a 7.5 MHz linear probe. The following structures were evaluated: long head of biceps tendon, supraspinatus, infraspinatus and subscapularis tendons, subacromial and subscapularis bursae, rotator cuff (thickness), calcifications, and glenohumeral and acromioclavicular joints. Statistical analysis was by Student's t test and chi-squared test. Results. Involvement of long head of biceps tendon (peritendinous fluid collection, changes of thickness, and/or echotexture) was significantly different between RA and PMR and between PD and PMR. Alterations in thickness and/or fibrillar pattern were evaluated in rotator cuff tendons: supraspinatus tendon was involved with significant differences between PD and both RA and PMR; the changes of subscapularis tendon were present, with significant differences between PD and both the other groups; the alterations of infraspinatus tendon were not statistically different between the 3 groups. Effusion within bursae was present, with significant differences only between RA and PD. The mean thickness of rotator cuff was significantly different between controls (6.2 mm) and both PD (5.3 mm) and RA (5.8 mm), and between PMR (6 mm) and PD. Evaluation of effusion within the glenohumeral joint (capsule-bone distance) showed significant differences between controls (2.4 mm) and both RA (4.2 mm) and PMR (4 mm), between RA and PD (2.6 mm), and between PMR and PD. Calcifications were present only in PD (21.3%) and RA (6.7%), with significant differences. Effusion within the acromioclavicular joint was present in RA (35.5%) and PD (20.5%), with significant differences. Conclusion. Shoulder sonography showed involvement of all structures in RA, the prevalence of effusion in PMR, and involvement mainly of tendons in PD
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
