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
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
METODE PENYETARAAN SKOR DAN UKURAN SAMPEL
Full text linkThis study is aimed to obtain information of different score variance result of equating linear method and equipercentile method for sample size 200, 400, and 800 in Ujian Akhir Sekolah Berstandar Nasional (UASBN). The research is important in considering the test device of UASBN shaped packages of different tests. Scores obtained from different packages can not be directly inferred the existence of differences in ability between them, because the difficulty level of the package used influencing these differrences. To overcome the differences are doing through equating. The method used is an experiment of two variables, equating method and the number of respondents. The experiments are not conducted during the learning process, but conducted after the score and the pattern of the answers obtained through UASBN. The population examinee UASBN SD/MI 2008/2009 for IPA subject matter at East Jakarta. Sampling uses random replacement technique. The hypothesis is tested using similarity variance. The results with α = 0,05 shows: (1) score variance equipercentile method (σ2ekp200) is not different to score variance linear method (σ2lin200) for the sample size 200, (2) score variance equipercentile method (σ2ekp400) is not different to score variance equating linear method (σ2lin400) for the sample size 400, and (3) score variance equipercentile method (σ2ekp800) is not different to score variance equating linear method (σ2lin800) for the sample size 800.Penelitian ini bertujuan memperoleh informasi perbedaan variansi skor hasil penyetaraan metode linear dan metode ekipersentil untuk ukuran sampel 200, 400, dan 800 pada Ujian Akhir Sekolah Berstandar Nasional (UASBN). Penelitian ini penting dilakukan mengingat perangkat tes UASBN berbentuk paket tes yang berbeda. Skor yang diperoleh dari paket berbeda tidak dapat langsung disimpulkan adanya perbedaan kemampuan antarpeserta tes, karena tingkat kesukaran paket yang digunakan mempengaruhi perbedaan tersebut. Untuk menanggulangi perbedaan dilakukan melalui penyetaraan (equating). Metode yang digunakan adalah eksperimen dua variabel, yaitu metode penyetaraan dan ukuran sampel. Eksperimen tidak dilakukan selama proses pembelajaran berlangsung, tetapi dilakukan setelah skor dan pola jawaban peserta diperoleh melalui UASBN. Populasi penelitian peserta UASBN SD/MI tahun pelajaran 2008/2009 mata pelajaran IPA di Jakarta Timur. Penarikan sampel menggunakan teknik penarikan sampel acak dengan pengembalian. Hipotesis diuji menggunakan teknik ana-lisis statistik uji kesamaan variansi. Hasil penelitian dengan α = 0,05 menunjukkan: (1) variansi skor penyetaraan metode ekipersentil (σ2ekp200) tidak berbeda dengan variansi skor penyetaraan metode linear (σ2lin200) untuk ukuran sampel 200, (2) variansi skor penyetaraan metode ekipersentil (σ2ekp400) tidak berbeda dengan variansi skor penyetaraan metode linear (σ2lin400) untuk ukuran sampel 400, dan (3) variansi skor penyetaraan metode ekipersentil (σ2ekp800) tidak berbeda dengan variansi skor penyetaraan metode linear (σ2lin800) untuk ukuran sampel 800
Paradigma dan Revolusi Sains (Telaah atas konsep pemikiran Thomas Samuel Kuhn dan implikasinya dalam teori belajar)
Full text linkAbstrak: Perubahan radikal dalam sains pada awal Eropa modern berpengaruh amat besar terhadap riset-riset praktis dan konsep berikutnya tentang masyarakat dan manusia itu sendiri. Pola pengembangan yang khas dari sebuah kematangan sains adalah transisi berturutan dari satu paradigma ke paradigma lain melalui proses revolusi. Sains pada dasarnya lebih dicirikan oleh paradigma dan revolusi yang menyertainya. Konsep sentral Kuhn adalah apa yang dinamakan dengan paradigma. Istilah paradigma identik dengan “skema” dalam teori belajar. Skema adalah suatu struktur mental atau kognisi yang dengannya seseorang secara intelektual beradaptasi dengan lingkungan sekitarnya. Skema ini akan beradaptasi dan berubah seiring perkembangan mentalnya. Teori belajar, dimana pembelajar mengkonstruksi “skemaskemanya” dikenal dengan konstruktivisme.
