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
Establishing the Correct Identity of Jalakumbhi in Ayurveda: A Critical Analysis Based on Various Literatures
Get PDFJalakumbhi is an effective Ayurvedic medicinal plant in the indigenous system of medicine which is found abundantly as a spread of a velvety carpet in mushy water bodies. This drug is known to Ayurveda practitioners since the Nighantu Kala. Jalakumbhi mentioned in Ayurvedic classics can be compared to Pistia stratiotes var. cuneata. but it is usually confused with Eichhornia crassipes also known as Pontederia crassipes thus making it controversial. This could be due to various reasons such as documentation defects in the manuscripts, same synonyms, habitat or morphology. All parts of the plant can be utilized for preparation of medicine for various diseases. The plant shows anti-thyroid, diuretic, antipyretic, anti-hemorrhoid, bronchodilator properties as well as can be used in various bleeding disorders in addition to in individuals suffering from emaciation, Sagrahani, Karnapaka, prickly heats etc. Here, an attempt is made to review the various therapeutic properties of Jalakumbhi along with its etymology, morphology and pharmacological aspects. We will also work to review and differentiate the plant which is confused as Jalakumbhi and rule out the reason behind such controversies. Various Ayurvedic and modern texts along with the latest researches have been analyzed and the concept concluded. The study shows both ayurvedic and modern explanation of this aquatic plant thus, giving correlation on the scientific basis of Ayurvedic drug Jalakumbhi and the use of it in various diseases. It will also set strong background for the drug which is mentioned as Jalakumbhi in our sacred compendium
Role of Nitya Virechan and Pathya in Cirrhotic Ascites
Get PDFCirrhosis of liver is an imperceptible disease due to any of the various long standing liver diseases which gradually leads to scarring of the liver tissues. This scarring or fibrosis is the consequence from the healing of the injured liver cells. Cirrhosis is the most common cause of ascites and accounts for almost 85% of all cases. [1] Cirrhotic ascites thus accounts as one of the major complications of Liver cirrhosis. Ayurvedic medicines give a promising result in the management of such decompensated liver disease. We hereby report a successfully managed case of a 53 year old male patient suffering from Cirrhotic Ascites. Post complication with hepatorenal syndrome and hepatogenous diabetes the patient was advised for liver and kidney transplant, as also his ascitic tapping was done multiple times; however he approached for alternative therapy in form of Ayurvedic medicine and was healed. Ascites can be correlated to Jalodar in Ayurvedic concept so the treatment protocol included the exclusive Ayurvedic treatment of Nitya virechan i.e., constant purgation mentioned as the principle treatment for Jalodar along with other supportive medications for liver malfunctioning. Therapeutic diet played an important role for the treatment. During and after treatment no adverse effects were found moreover patient was at comfort with the treatment and the distension of abdomen was negligible, patient also stopped taking insulin, while swelling was reduced remarkably
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
