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
STATUS POLIGAMI DALAM HUKUM ISLAM (Telaah atas Berbagai Kesalahan Memahami Nas dan Praktik Poligami)
Full text linkThis article discuss how the actual legal status of polygamy in Islamic law, by looking at the situation and the existing social conditions. Because it can not be denied that customary law will always apply in the midst of the people of Indonesia. Appropriate and inappropriate attitudes, natural and unnatural, rude and disrespectful, still very important in the oriental societies like Indonesia. Of course the rahmah Islamic law will negotiate for customary law and society perspective. So as to create an equitable justice, and losses caused by polygamy will be deleted.
[Artikel ini membahas bagaimana sebenarnya status hukum poligami dalam hukum Islam, dengan melihat situasi dan kondisi kemasyarakatan yang ada. Karena tidak dapat dipungkiri bahwa hukum adat akan selalu berlaku di tengah-tengah masyarakat Indonesia. Sikap pantas dan tidak pantas, wajar dan tidak wajar, sopan dan tidak sopan, masih sangat kental di dalam masyarakat ketimuran seperti Indonesia. Tentu saja hukum Islam yang rah}mah akan melakukan negosiasi terhadap hukum adat dan cara pandang masyarakat. Sehingga tercipta keadilan yang merata dan terhapuslah kerugian demi kerugian yang dirasakan oleh pihak-pihak yang merasa dirinya dirugikan karena adanya
poligami.
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
In vitro transformation of adult rat liver cells by 3'-methyl-4-dimethylaminoazobenzene.
No full textPrimary cultures of liver cells from normal adult rats were treated with 3'-methyl-4-dimethylaminoazobenzene (3'-Me-DAB) at various concentrations for 6 days. 3'-Me-DAB treatment induced rapid proliferation of epithelial clear cells with chromosomal abnormalities and gamma-glutamyl transpeptidase (GGT) activity. In early culture, marker chromosomes were detected in 13 of 44 3'-Me-DAB-treated cultures but not in control cultures. GGT activity was not detected in the epithelial clear cells in either 3'-Me-DAB-treated or control cultures. In late culture, 21 cell lines established from 39 carcinogen-treated cultures consisted of 3 diploid cell lines, 5 pseudodiploid cell lines and 13 aneuploid cell lines. Eighteen of these 21 cell lines had marker chromosomes. Of the 2 cell lines established from 15 control cultures both were aneuploid, but a marker chromosome was detected in only one of these. GGT activity was detected in 11 of 21 cell lines established from the carcinogen-treated cultures but not in those from control cultures. Morphological features of the cell lines which varied from normal to cancerous included polymorphism, increased nuclear/cytoplasmic ratio and prominent nucleoli. No cell line established in this study developed tumors in host rats during a 1-year observation period.</p
