    Going Beyond Counting First Authors in Author Co-citation Analysis

    The 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

    “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 link
    We 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

    Penelitian ini berangkat dari kondisi rendahnya hasil belajar siswa dalam pembelajaran tematik kelas V SD Negeri 1 Kopen Kecamatan Jatipurno dapat diketahui dari rata-rata nilai ulangan harian siswa. Pada kegiatan ulangan harian yang diadakan guru menunjukkan perolehan nilai rata-rata siswa kurang dari 73. Dari 24 siswa yang mengikuti ulangan harian yang dilakukan, hanya 37,5 % yang mendapatkan nilai di atas 73, sedangkan 62,5 % siswa mendapat nilai dibawah 73.. Salah satu model pembelajaran yang dapat diterapkan untuk siswa kelas V di SD Negeri 1 Kopen Kecamatan Jatipurno adalah model pembelajaran Learning Cycle terutama pada muatan Ilmu Pengetahuan Alam tema Ekosistem. Berdasarkan hasil penelitian tindakan kelas (PTK) pada tema ekosistem muatan IPA yang berlangsung selama 2 Siklus dan setiap Siklus dua kali pertemuan dengan alokasi waktu 2 X 35 menit, maka penulis dapat menyimpulkan: Bahwa penggunaan model pembelajaran Learning Cycle dapat meningkatkan hasil belajar peserta didik Kelas V SDN 1 Kopen semester 1 Kecamatan Jatipurno Kabupaten Wonogiri Tahun Pelajaran 2020/2021, ditunjukkan dengan hasil ketuntasan belajar peserta didik sebelum perbaikan hanya 9 peserta didik (37,5 %) sedangkan pada Siklus I naik sebanyak 11 peserta didik (45,8 %) dan pada Siklus II naik menjadi 22 peserta didik (91,7 %) telah memenuhi KKM yang ditentukan.   Improving learning outcomes for fifth grade students through the learning cycle learning model. This research departs from the low condition of student learning outcomes in thematic learning in grade V SD Negeri 1 Kopen, Jatipurno District, it can be seen from the average score of students\u27 daily tests. In the daily test activities held by the teacher, the average score of students was less than 73. Of the 24 students who took the daily test, only 37.5% got a score above 73, while 62.5% of the students scored below 73 .. One learning model that can be applied to fifth grade students at SD Negeri 1 Kopen, Jatipurno District is the Learning Cycle learning model, especially on the Natural Science content with the theme of Ecosystems. Based on the results of classroom action research (PTK) on the theme of the IPA content ecosystem which lasted for 2 cycles and each cycle had two meetings with a time allocation of 2 X 35 minutes, the authors concluded: That the use of the Learning Cycle learning model can improve the learning outcomes of Class V students at SDN 1 Kopen semester 1 Jatipurno District, Wonogiri Regency Academic Year 2020/2021, is shown by the results of learning completeness of students before improvement only 9 students (37.5%) while in Cycle I increased by 11 students (45.8%) and in Cycle II increased to 22 students (91.7%) had fulfilled the specified KKM

    Dispelling the Myths Behind First-author Citation Counts

    We 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 text
    We 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
