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
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

A Hospital Based Comparative Study the Post Operative Pain, Duration of Procedure & Incidence of Complications Between Open Transinguinal Preperitoneal Hernia Repair and Lichenstein’s Hernia Repair
Get PDFBackground: Inguinal hernias are present in 1.7% of the world population. The Trans Inguinal Preperitoneal (TIPP) Hernia Repair (using prolene mesh) resulted in greater patient comfort with reduced post operative pain and also decreases the number of complications and recurrence rate and that it can be recommended for all primary unilateral Inguinal Hernias. The aim of this study to compare the post operative pain, duration of procedure & incidence of complications between transinguinal preperitoneal repair and lichtensteins repair procedures. Materials & Methods: A hospital based prospective study done 40 patients of inguinal hernias with ASA I or II, attending the district hospital Dholpur, in our surgical unit over a period 1 year. All cases were selected at random irrespective of the type of inguinal hernia, the age of the patient and the size of the defect. The material used for repair is monofilament polypropylene clear non absorbable synthetic knitted surgical mesh. About 20 cases of transinguinal pre peritoneal mesh repair & 20 cases of lichtensteins repair. Post operative pain, scrotal collection, seroma, cord oedema and wound infection were looked for they were asked to come for regular follow-up visit after discharge during each follow-up visit, the patients were assessed for pain, surgical site infection and recurrence.Results: The mean age of the patients subjected to lichenstein repair was 52.76 years and for TIPP it was 49.24yrs. The duration of operation was more in the TIIP group and was statistically significant (p < 0.05*). During the first follow up of patients at one month it was noticed that 20% of patients who underwent linchenstein repair had complications of SSI, cord edema, recurrence and pain. At second follow up it was noticed that only 2 patient who underwent LR had sensory loss. Occurrence of pain at 3 rd month between the lichenstein and TIPP repair is not statistically significant (p>0.05).Conclusion: We concluded that the transinguinal pre peritoneal mesh repair is an amazing simplistic technique which gives an approach to inguinal, femoral and obturator hernias and bears the same anatomical relationship in TEP and TAPP approaches which gives a better understanding of the TEP and TAPP procedures
A Hospital Based Prospective Study to Compare the Outcome of Perianal Surgery Wound when Using Silver Colloidal Solution Spray V/S Povidone Iodine Sitz-Bath
Get PDFBackground: The pain of anal ulcer is intolerable and always disproportionate to the severity of the physical lesion. Many different wound irrigation solutions, including soaps, antibiotics and antiseptics, have been used to reduce surgical site infection. The aim of this study to compare the outcome of perianal surgery wound when using silver colloidal solution spray v/s povidone iodine sitz-bath. Materials & Methods: A hospital based prospective study done 50 patients of perianal surgery with ASA I or II, attending the district hospital Dholpur, in our surgical unit over a period 1 year. Critically ill patients and patients with underlying bone osteomyelitis or malignancy were excluded. Fifty patients were randomly assigned to receive silver colloidal solution spray (Group A) or a twice-daily sitz bath along with povidone iodine (Group B). Weekly pain score and patient satisfaction score were evaluated on visual analogue scores. Results: Our study showed that there was no significant difference in age, gender distribution and the number of excised haemorrhoid piles between the two groups. No significant difference in postoperative mean pain score between groups (P >0.05) was noticed. The satisfaction score was higher in the sitz bath group with povidone iodine when compared with the silver colloidal solution spray group; however, it did not reach a statistically significant level. Conclusion: We concluded that povidone-iodine with sitz bath may be effective in preventing surgical site infection as compare to silver colloidal solution spray. However, more studies, especially double-blind RCTs, should be conducted to determine the “ideal” solution of povidone-iodine irrigation as well as specific risks associated with its use
