Going Beyond Counting First Authors in Author Co-citation Analysis
No full textThe 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

Skripsi, Jurusan Pendidikan Sekolah Dasar, Fakultas Keguruan dan Ilmu Pendidikan, Universitas Syiah Kuala. Pembimbing:(1)Dr. Dra. Israwati, M.Si(2) Aida Fitri, S.Pd, M.PdKata kunci: Media, Video Tutorial, Meningkatkan Hasil Belajar, Menganyam. Belajar adalah suatu proses usaha yang dilakukan individu untuk memperoleh suatu perubahan tingkah laku yang baru secara keseluruhan sebagai hasil pengalaman individu itu sendiri dalam interaksi dengan lingkungannya. Tujuan penelitian ini adalah untuk mengetahui peningkatan hasil belajar siswa kelas V pada materi menganyam dengan penerapan media video tutorial. Penelitian ini menggunakan jenis penelitian tindakan kelas (PTK). Subjek dalam penelitian ini adalah 30 siswa SD Negeri Garot Aceh Besar. Penelitian dilakukan dalam dua siklus. Teknik pengumpulan data yang digunakan dalam penelitian ini adalah observasi dan tes. Teknik analisis data yang digunakan adalah teknik deskriptif yaitu dengan menggunakan rumus persentase. P = F/N x 100%, keterangan persentase (P), frekuensi (F), jumlah siswa (N), 100% bilangan konstanta (tetap).Hasil penelitian menunjukkan bahwa penerapan media video tutorial dalam pembelajaran seni rupa pada materi menganyam siswa saat dilaksanakan kegiatan menganyam pada siklus I adanya kendala, sehingga hasil belajar siswa belum mencapai nilai KKM, oleh karena itu perlu ditindak lanjuti pada siklus berikutnya, kegiatan menganyam pada siklus II hasil belajar siswa sudah meningkat mencapai nilai KKM yaitu 75 yang sudah ditetapkan oleh sekolah. Setelah diterapkan media video tutorial hasil menganyam siswa pada siklus I mendapatkan nilai 60% (C) belum mencapai nilai KKM, perlu ditindak lanjuti ke siklus II. Nilai yang diperoleh pada saat pembelajaran siklus II yaitu 80% (B) sudah memenuhi nilai KKM. Hal ini menunjukkan adanya peningkatan persentase ketercapaian hasil belajar siswa. Peningkatan hasil belajar dengan kegiatan menganyam pada siswa kelas V SD Negeri Garot Aceh Besar, memperoleh persentase dan katagori bahwa tingkat kemampuan siswa dalam menganyam pada siklus I dan II yaitu 52,67% (C) dan 80% (B) peningkatan antara kedua siklus sebesar 27%
Appropriate Similarity Measures for Author Cocitation Analysis
No full textWe 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

Correction to: European Archives of Paediatric Dentistry (2022) 23:23–38 https://doi.org/10.1007/s40368-021-00646-x Some odds ratios and two figures were incorrectly transferred from the supplementary material to the abstract and the text. The figure at the bottom of page 25 of the supplementary material has also been modified. These changes do not alter the interpretation of the results and do not affect the conclusions of the publication. The correct text including the corrected odds ratios is presented below: Perinatal factors: Prematurity (OR = 1.59; 95% CI 1.25–2.04; p = 0.0002) and caesarean delivery (OR = 1.13; 95% CI 1.01,1.28; p = 0.04) are associated with an increased risk of developing MIH. Birth complications are also highlighted. These three factors can lead to hypoxia, and children with perinatal hypoxia are more likely to develop MIH (OR = 2.59; 95% CI 1.69–3.98; p < 0.0001). Following the exclusion of these studies, hypoxia at birth (OR = 2.59; 95% CI 1.69–3.98; p < 0.0001; Fig. 4), caesarean (OR = 1.13; 95% CI 1.01,1.28; p = 0.04; Fig. 5) and prematurity (OR = 1.59; 95% CI 1.25–2.04; p = 0.0002; Fig. 6) were associated with MIH (Table 2). (Figure presented.) (Figure presented.) Meta-analysis (forest plot and funnel plot) for caesarean Meta-analysis (forest plot and funnel plot) for prematurity After excluding outlying studies that severely increased heterogeneity, factors such as gastric disorders (OR = 1.99; 95% CI 1.37–2.88; p = 0.0003), fever (OR = 1.44; 95% CI 1.19–1.75; p = 0.0002), kidney diseases (OR = 2.70; 95% CI 1.07–6.82; p = 0.04), pneumonia (OR = 1.49; 95% CI 1.15–1.94; p = 0.03), asthma (OR = 1.56; 95% CI 1.10–2.20; p = 0.01) and antibiotic use (OR = 1.20; 95% CI 1.01–1.44; p = 0.04) were also found to be associated with MIH (Tables 2, 3). It was finally determined that prematurity is associated with MIH (It was finally determined that prematurity is associated with MIH (OR = 1.45; 95% CI 1.24–1.70; p = 0.0002). Additionally, Table 3, Figs. 5 and 6 and the bottom figure in Supplementary materials p25 are replaced and included in the present correction as supplementary material. Finally, in the publication ‘Lygidakis NA, Garot E, Somani C, Taylor GD, Rouas P, Wong FSL. Best clinical practice guidance for clinicians dealing with children presenting with molar-incisor-hypomineralisation (MIH): an updated European Academy of Paediatric Dentistry policy document. Eur Arch Paediatr Dent. 2022;23(1):3–21, the following odds ratios were affected and the correct ones are presented below, again not affecting the results interpretation and Conclusions: Few of the above-mentioned discrepancies affect also minimally the publication ‘Lygidakis NA, Garot E, Somani C, et al.

Dispelling the Myths Behind First-author Citation Counts
No full textWe 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

Mapping the Discipline of the Olympic Games An Author-Cocitation Analysis
No full textThe authors conducted an author cocitation analysis on prominent authors writing about the Olympics during the 1990s. Author cocitation is an established bibliometric technique that can be used to measure the relative similarities of topics written about by the cited authors. This enables a visual representation of the “intellectual space” of the discipline, in this case the Olympics, to be created for the period under review. So core and peripheral research areas are identified, along with their major contributors. The representation appears as a two-dimensional cluster-enhanced map. Subject expertise was then applied to the results to place labels on the generated clusters of authors and their topics
