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
Sebaran Geographic Tongue pada Mahasiswa Fakultas Kedokteran Gigi Universitas Gadjah Mada Yogyakarta
Get PDFTongue is barometer of health and sytemic condition. Geographic tongue hasn ’t been dangerous and asymptomatic lesion in papilla of the tongue. The aim of this study is to know geographic tongue distribution on dentistry student of Gadjah Mada University of Yogyakarta. The study was descriptive research. Limitation of the population are student of the Faculty of Dentistry, Gadjah Mada University in the academic year 1999-2003. The samples were 362 people. The method were clinical examination of dorsum of the tongue and oral hygiene index (OHI). The result were analyzed with chi-square test. The result of this study are 8 (2,21%) from 362 samples are geographic tongue, 5 male (6,25%) and 3 female (1,06%). Eight cases of geographic tongue are distributed in the each academic year, they are 3 cases (4,17%) on academic year of1999, 1 case (1,32%) on academic year of2000, 2 cases (2,82%) on academic year of2001, 1 case (1,43%) on academic year of2002 and 1 case (1,37%) on academic year 2003. The conclution is that gender is significant but oral hygiene and academic year aren ’t significant in case of geographic tongue. Distribution of geographic tongue on dentistry student of Gadjah Mada University have variation.Lidah adalah barometer kesehatan yang mencerminkan kondisi sistemik. Geographic tongue adalah kondisi yang tidak membahayakan biasanya merupakan kondisi asimtomatik dengan etiologi tidak diketahui yang menyangkut epitel lidah. Tujuan penelitian ini adalah untuk mengetahui gambaran sebaran geographic tongue pada mahasiswa Fakultas Kedokteran Gigi Universitas Gadjah Mada Yogyakarta. Jenis penelitian adalah penelitian deskriptif. Batasan populasi adalah mahasiswa Fakultas Kedokteran Gigi Universitas Gadjah Mada Yogyakarta angkatan 1999 - 2003. Jumlah sampel berjumlah 362. Cara penelitian yaitu dengan melakukan pemeriksaan klinis pada permukaan dorsal lidah dan status kebersihan mulut (oral hygiene index/OHI). Hasil penelitian dianalisis dengan uji chi-square. Hasil penelitian menunjukkan dari 362 mahasiswa yang diperiksa ditemukan 8 kasus (2,21%) geographic tongue yang terdiri dari 5 pria (6,25%) dan 3 wanita (1,06%). Delapan penderita geographic tongue tersebar di tiap tahun angkatan akademik, terdiri dari 3 orang (4,17%) angkatan 1999, 1 orang (1,32%) angkatan 2000, 2 orang (2,82%) angkatan 2001, 1 orang (1,43%) angkatan 2002 dan 1 orang (1,37%) angkatan 2003. Semua penderita geographic tongue memilki status kebersihan mulut baik. Disimpulkan bahwa sebaran geographic tongue di Fakultas Kedokteran Gigi Universitas Gadjah Mada bervariasi, jenis kelamin berpengaruh terhadap kejadian geographic tongue, sedangkan tahun angkatan akademik dan status kebersihan mulut tidak berpengaruh terhadap kejadian geographic tongue
