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
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
Formulasi Pasta Gigi Herbal Ekstrak Daun Sukun (Artocarpus Altilis) Dan Uji Aktivitas Antibakteri Terhadap Bakteri Streptococcus mutans
Full text linkPrevalensi karies di Indonesia pada tahun 2013 berkisar 72,3%. Karies gigi yang disebabkan oleh bakteri Streptococcus mutans dapat dihindari dengan bantuan senyawa kimiawi maupun tindakan mekanis. Pengunaan bahan alternatif dari bahan alam dalam sediaan pasta gigi sedang dikemabangkan. Salah satu tanaman yang dapat digunakan adalah daun sukun (Artocarpusaltilis). Jenis penelitian ini adalah penelitian eksperimental laboratorium. Pada pembuatan sediaan pasta gigi herbal ekstrak daun sukun dibuat 3 formula dengan konsentrasi ekstrak masing-masing 10%, 15% dan 20%. Penelitian ini menggunakan uji ANOVA (Analysis Of Variance) untuk melihat perbedaan signifikan dari masing-masing perlakuan. Hasil penelitian menunjukkan hasil pengujian evaluasi fisik yang palik baik adalah formula III. Pada pengujian aktivitas antibakteri diperoleh daya hambat paling baik pada pasta gigi herbal adalah formula 3 dengan rata-rata luas daya hambat sebesar 21,37mm yang dapat dikategorikan memiliki daya hambat yang sangat kuat. Hasil uji ANOVA juga diperoleh nilai p<0,005 yang menunjukkan adanya perbedaan signifikan dari masing-masing konsentrasi. Sediaan pasta gigi herbal ekstrak daun sukun (Artocarpusaltilis) dapat disimpulkan bahwa pembuatan sediaan pasta gigi herbal stabil pada evaluasi fisik dan memiliki aktivitas antibakteri terhadap bakteri Streptococcus mutans
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
ANTITUSSIVE ACTIVITY ASSAYOF SAGE (LANTANA CAMARA L.)LEAVES BASED ON THE BREATHING PATTERN OF MALE GUINEA PIGS USING ADOBE AUDITION 1.5 PROGRAM
Full text linkObjective: The present study was aimed to assay antitussive activity of Sage (Lantana camara L.)leavesMethods: Antitussive Assay was conducted based on The Breathing Pattern of Male Guinea Pigs Using Adobe Audition 1.5 Program.Results: Comparison of the frequency of breathing patterns guinea pig groups sage (Lantana camara L.)Â leaves water fraction at a dose of 4.58 mg/kg bw dose of 9.17 mg/kg bw and doses of 18.35 mg/kg bw statistically significantly different results (p<0.05), as well as the ratio of intensity of the breathing pattern of the guinea pig. As for the water extract, significant differences in the frequency comparison guinea pig respiratory pattern is only shown at a dose of 18.35 mg/kg bw on the other side for its intensity did not show significant differences (p<0.05).Conclusion: Ethanol extract of sage leaves in the form of three fractionation (ethyl acetate, n-hexane, and water) can improve the breathing pattern guinea pig cough, especially at a dose of 18.35 mg/kg bw.Â
