No full textWe thank Drs. Kumawat and Chawla1 for their interest and insightful comments on our study titled “Comparative analysis of retinal reattachment surgery with or without internal limiting membrane peeling to prevent postoperative macular pucker.”2 First, the authors mention in their introducing comments that many other factors are responsible for epiretinal membrane (ERM) formation including duration of retinal detachment, proliferative vitreoretinopathy (PVR), number of retinal breaks, size of retinal breaks, and postoperative anti-inflammatory treatment, etc. We entirely agree with the authors and have hence performed a regression analysis to see the confounding influence of factors (with sufficient numbers in our data set) such as PVR and presence of giant retinal tears on ERM formation in our series. Yet, the authors have commented that these issues have not been addressed. In our opinion, ERM is an extension of the PVR process, and irrespective of the underlying cause, advance PVR grade C2 or more has risk of developing ERM, also internal limiting membrane (ILM) peeling can be extremely challenging in a detached retina with extensive PVR, so we have excluded them from our study. Reliability of preoperative optical coherence tomography for macular thickness and morphology in RD depends on configuration of detached retina, PVR changes, and media opacities. Considering these facts, it was not possible to evaluate preoperative optical coherence tomography findings in all the cases. In our study, we have defined the presence of ERM on optical coherence tomography even if it did not affect visual acuity and may not have been obvious on slit-lamp biomicroscopy. Functional outcome in terms of visually significant ERM during the follow-up (visual acuity less than 0.5 log MAR) developed in
four of seven eyes in ILM peeling group and 18 of 25 eyes of non–ILM-peeling group. In our article, we have already enumerated various complications and retinal structural changes after ILM peeling. It is clearly mentioned that we do not report any such complications in our study. Finally, the authors conclude by saying that larger prospective randomized controlled trials studying morphological and functional changes may be needed before we practice ILM peeling in all retinal detachment surgeries which echoes the concluding remarks of our original publication verbati
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
Evaluation of the Morphology of Ganglion Cell Complex and Functional Outcomes after Internal Limiting Membrane Peeling with Macular Abrasion in Idiopathic Macular Hole
Get PDFAim. This study aims to evaluate the morphology of ganglion cell complex (GCC) along with functional outcomes in patients undergoing vitrectomy with ILM peeling and macular abrasion with Tano diamond dusted membrane scrapers (DDMS) for three different stages of the idiopathic macular hole (IMH). Methods. This retrospective study was conducted between April 2019 and December 2019. 33 patients with IMH were included and divided into three groups: stage I, stage II, and stage IV. All patients were subjected to vitrectomy with ILM peeling. Gentle and vigorous macular abrasion was additionally performed for stage II and stage IV patients, respectively. The best-corrected visual acuity (BCVA), GCC thickness (measured by spectral domain-optical coherence tomography (SD-OCT)), and photopic contrast sensitivity (Rodenstock CV 900 Chart Panel) were determined before surgery and at 1- and 3-month follow-ups. Results. Closure of MH was achieved in all the patients. The difference between the preoperative and one- and three-month postoperative values of BCVA was statistically significant in the three groups (P<0.01). Contrast sensitivity progressively improved in all patients and was statistically significant (P<0.01). The reduction in GCC thickness during follow-up was 34%–42% of the preoperative measurements. On comparing the mean GCC thickness of the operated and healthy eyes, it was not statistically significant in stage I patients. However, the same when done in stage II and IV was statistically significant with P value < 0.05 and P<0.01, respectively. Conclusion. Combining ILM peeling with macular abrasion in advanced stages of MH may facilitate its closure without significantly affecting the functional outcome
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
