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

Penggunaan Model Problem-Based Learning (PBL) Untuk Meningkatkan Hasil Belajar Siswa Pada Pembelajaran Tematik Terpadu Kelas V SD
Get PDFThis study was inspired by field data that do not conform to ideal conditions, so there is still little impact on student learning outcomes. In general, this study aims to describe how integrated thematic learning in grade V SD using the Problem Based Learning (PBL) model improved student learning outcomes. Classroom action research, also known as CAR, employs both qualitative and quantitative methods. The study was carried out during the second semester of the academic year 2022–2023. The outcomes showed that in arranging cycle I acquired a normal of 87.45% then expanded in cycle II to 97.2%, execution of learning on the educator viewpoint, cycle I got a normal of 82.1% and encountered an expansion in cycle II to 92.8% and on the understudy perspective, cycle I got a typical score of 82.1% then expanded in cycle II to 92.8%, understudy learning results in cycle I got a typical score of 76.81 then expanded in cycle II to 89.73 . The Problem-Based Learning (PBL) model has the potential to enhance student learning outcomes in class V SD thematic learnin
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
Pengembangan Media Pembelajaran Berbasis Gimkit pada Pembelajaran Bahasa Indonesia Kelas V SD di Kota Bukittinggi
Get PDFPenelitian ini dilatar belakangi oleh minimnya penggunaan IT yang sudah difasilitasi oleh sekolah dalam menciptakan media pembelajaran yang kreatif, inovatif, menarik dan mengikuti perkembangan zaman. Sehingga guru perlu meningkatkan dan memanfaatkan media dan fasilitas sekolah dalam menciptakan media pembelajaran. Jenis penelitian yang digunakan pada penelitian ini adalah penelitian pengembangan Research and Development (R&D) menggunakan model ADDIE. Model ADDIE ini terdiri dari lima Langkah yakni analysis, design, development, implementation dan evaluation. Hasil penelitian media pembelajaran memperoleh Tingkat kevalidan dari aspek materi yakni 90%, aspek Bahasa dengan persentase 91% aspek media dengan persentase yakni 90% dengan kategori sangat valid. Selanjutnya hasil uji praktikalitas dari respon guru di sekolah uji coba adalah 92,5% dan perenstase dari peserta didik sebesar 87,7% dengan kategori sangat praktis. Adapun hasil praktikalitas di sekolah penelitian, praktikalitas guru memperoleh persentase sebesar 95% dengan kategori sangat praktis dan dari peserta didik memperoleh hasil 89,5% dengan kategori sangat praktis. Hasil uji efektivitas pada sekolah uji coba berdasarkan hasil uji N-Gain memeperoleh nilai sebesar 76,25 dengan kategori efektif, hasil uji efektivitas pada sekolah penelitian (eksperimen ) memeperoleh hasil 79,16 dengan kategori efektif dan terakhir pada sekolah control yaitu berdasarkan hasil pengolahan data hasil pretest dan postest di N-Gain mendapatkan nilai 76,22 dengan kategori efektif. Dengan demikian dapat disimpulkan bahwasanya media pembelajaran berbasis Gimkit pada materi Kata Sinonim dan Antonim di kelas V SD Kota Bukittinggi dapat dinyatakan valid, praktis, dan efektif untuk digunakan didalam proses pembelajaran
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
