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
Analisa Antifungal Ekstrak Etanol Biji Alpukat Terhadap Pertumbuhan Jamur Colletotrichum sp. pada Buah Cabai Rawit (Capsicum frutescens)
Get PDFPenelitian ini bertujuan untuk mengetahui potensi ekstrak biji alpukat sebagai antifungi dan konsentrasi optimum ekstrak biji alpukat dalam menghambat pertumbuhan jamur Colletotrichum. Metode yang digunakan dalam penelitian ini adalah metode eksperimental berskala laboratorium. Sampel biji alpukat diekstraksi dengan metode maserasi menggunakan pelarut etanol 96%. Hasil ekstraksi dilanjutankan dengan uji penghambatan ekstrak etanol terhadap jamur Colletotrichum dengan variasi konsentrasi 20%, 40%, 60%, 80% dan 100% sedangkan kontrol negatif (-) menggunakan Topsin M 70 WP 0,2%. Hasil penelitian menyatakan bahwa ekstrak etanol biji alpukat memberikan pengaruh nyata terhadap aktivitas jamur Colletotrichum dengan konsentrasi optimum 40% dan sudah ada sejak hari ke 4 setelah inkubasi yang diketahui dari diameter pertumbuhan jamur.This study aimed to assess the potential of avocado seed extract as an antifungal agent and to determine the optimum concentration of avocado seed extract in inhibiting the growth of Colletotrichum. This research used laboratory- scale experimental methods. Inhibition test of extract towards Colletotrichum was carried out using poison food method using following extract concentration 20%, 40%, 60%, 80% and 100% Topsin M Wp 0.2% were used as negatif control. The result showed that avocado seed extract had a significant antifungal activity against Colletotrichum at the consentration of 40%, the effect was emerged since the 4th day of incubation which was observed by measuring fungal growth diameter
