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
Functional outcome of Column-specific Fixation of Complex Tibial Plateau Fractures
Get PDFBackground: Complex tibial plateau fractures are usually high energy injuries presenting with significant articular and soft tissue damage in a major weight bearing joint. The knee is a complex dynamic joint that is subjected to many forces during normal activities, so intact articular surface of tibial plateau is one of important factors to keep the geometry and alignment of the knee joint to act in harmony to perform its crucial function as a flexible weight bearing joint. Material and Methods: This prospective study was conducted in the Department of Orthopaedics, a Tertiary Care Teaching Hospital, 27 patients with displaced tibial plateau fractures with posterior column involvement were selected for the study. All age group Patients with complex proximal tibia plateau fractures & closed injuries were included in this study. Involving two or more columns were classified based on the new three column classification system, patients with normal neurovascular function before primary surgery, patients with closed fractures, patients with good soft tissue condition, and patients without serious medical diseases and obvious surgical contraindications. Result: In our study, the most of the patients were belongs to 21-30 years old 13 (48.1%). In table 2, predominant were males 92.5% and females were of 7.4%. In our study majority of patients were Three-column fractures, followed by Two-column fracture and Single-column fractures. After operative procedure, 3 (11.1%) patients got discharged on post op day-7, 14 (51.8%) patients on post op day-8, 7 (25.9%) on post op day-9 and 3 (11.1%) on post op day-10. Conclusion: Using this new column specific strategy to the treatment of these two or more column tibial plateau fracture injuries, which involves evaluation of three columns, we believe we achieved satisfactory results
Open versus arthroscopic surgical management for recurrent anterior instability of the shoulder: A prospective Study
Get PDFBackground: The best surgical treatment for recurrent anterior shoulder instability is still up for debate. We didn't know much about the advantages and disadvantages of old open and newer arthroscopic methods. We expected that regardless of surgical approach, all patients' results would be identical. Material and Methods: This is a comparative study, Prospective and cross-sectional study conducted at Department of Orthopaedics, Tertiary care Teaching Hospital over a period of 1 year. According to the surgical management, they were divided into two groups: Group A Patients had either open surgery with suture anchors and capsular shift. Group B Arthroscopic Surgery Suture anchors and suture capsulorrhaphy are used. Result: In our study, time of surgery was significantly longer in the arthroscopic surgery group than the open surgery group (P < 0.05). Intraoperative blood loss was significantly more in the open surgery group than the arthroscopic surgery group (P < 0.0001) and total time of hospital stay was significantly more in the open surgery than the arthroscopic surgery group (P < 0.05). VAS pain scores after the surgery was significantly higher in the open surgery group than the arthroscopic surgery group (P > 0.05). Increase in Rowe score after the surgery was significantly higher in the open surgery group than the arthroscopic surgery group. Conclusion: Recurrent anterior shoulder instability may be safely treated with arthroscopic stabilisation. Range of motion is marginally better following arthroscopic treatment when compared with open repair. Although open surgery is more intrusive than arthroscopic Bankart surgery, it should still be considered for certain patients because of its impact on shoulder joint long-term stability
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
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
