Neurodevelopmental disorders among Indian children: needs attention
No full textNeurodevelopmental disabilities (NDDs) have always been an important concern but yet to be considered as a significant public health problem for children of low and middle income countries including India. It has been suggested that 85% of children with NDDs live in low and middle income countries but there are little data to support this because of lack of a comprehensive, valid, reliable and culturally sensitive screening as well as diagnostic tools and gloomy picture of research in this field due to myriad reasons. Till date there is no single best treatment package available for all children with neurodevelopmental disorders. So the preventive measures have prime importance in reducing the burden of neurodevelopmental disorders

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
The Potential Benefits of Pegylated Erythropoietin in Lowering Anemia in Individuals with Chronic Kidney Disease
Full text linkBackground: The clinical debut of erythropoiesis-stimulating medicines (ESAs) radically altered anaemia care. The effect of erythropoietin (EPO), pegylated erythropoietin and mircera on anaemia in chronic kidney disease (CKD) patients receiving continuous haemodialysis, peritoneal dialysis, or no dialysis was studied in this retrospective analysis.
Methods: The retrospective analysis comprised of 490 CKD patients with erythropoietin hyporesponsiveness who were either on haemodialysis or peritoneal dialysis or not on dialysis. The patients’ records were separated into three groups: (a) those with CKD 3-5 (without dialysis), (b) those on haemodialysis, and (c) those on peritoneal dialysis (PD). Serum ferritin, haemoglobin, and transferrin saturation were measured. Serum ferritin was determined using a two-site sandwich immunoassay based on direct chemiluminometric technique, which employs two antiferritin antibodies at constant concentrations that are collated and statistically observed using bivariate analysis.
Result: The participants’ mean ages were 46.9±20.4, 60.5±9.7, and 48.2±10.1 years for peritoneal dialysis patients, CKD patients on haemodialysis, and CKD 3 5 patients without dialysis, respectively. In all categories, hypertension was the most common cause of CKD, followed by type 2 diabetes. Patients on peritoneal dialysis have higher haemoglobin (Hb) levels than patients on haemodialysis (P<0.016), but there is no statistically significant difference between patients on peritoneal dialysis and patients not on dialysis. The analysis revealed that there was a substantial increase in Hb from 8.8±1.2 to 10.9±1.2 g/dl in all groups (p <0.05).
Conclusion: Pegylated erythropoietin outperforms mircera in overcoming erythropoietin hyporesponsiveness and maintaining stable haemoglobin levels in dialysis-dependent CKD patients. This is a retrospective analysis hence it may not reflect the true status of the population and is less likely to generalise the findings; consequently, more research is needed
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
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
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
