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
Variations on the Author
No full text“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
KEMAMPUAN BERPIKIR KREATIF MATEMATIS SISWA DALAM MEMECAHKAN MASALAH BANGUN RUANG
No full textKemampuan berpikir kreatif matematis merupakan aspek penting dalam pembelajaran matematika yang dapat membantu siswa dalam memecahkan masalah secara inovatif dan kreatif, terutama yang terkait dengan materi bangun ruang. Penelitian ini bertujuan untuk menganalisis kemampuan berpikir kreatif matematis siswa dalam menyelesaikan soal bangun ruang berdasarkan empat indikator, yaitu kelancaran (fluency), keluwesan (flexibility), orisinalitas (originality), dan keterperincian (elaboration). Penelitian ini menggunakan pendekatan deskriptif kualitatif dengan teknik pengumpulan data melalui tes uraian dan wawancara mendalam yang kemudian divalidasi dengan menggunakan triangulasi teknik. Hasil penelitian menunjukkan bahwa siswa telah memenuhi indikator kelancaran dengan memberikan lebih dari satu solusi yang sistematis. Namun, fleksibilitas masih kurang optimal karena siswa belum mampu menggunakan metode pemecahan masalah lainnya. Dalam hal orisinalitas, siswa mampu menemukan solusi mandiri tanpa adanya bantuan eksternal. Sementara dalam hal keterperincian, siswa mampu mencapai indikator tersebut secara struktural meskipun terdapat kekurangan dalam penyajian informasi yang detail. Penelitian ini menekankan pentingnya pembelajaran yang mendorong pengembangan kemampuan berpikir kreatif matematis dalam mendukung penyelesaian masalah yang lebih variatif dan aplikatif, khususnya melalui pendekatan yang lebih interaktif dan kontekstual
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
PENGARUH KOMBINASI MODEL PEMBELAJARAN KOOPERATIF DAN MOTIVASI BELAJAR TERHADAP HASIL BELAJAR MATEMATIKA DENGAN MEMPERHITUNGKAN KOVARIAT SELF EFFICACY SISWA SMP
No full textPenelitian eksperimen desain 3x3 faktorial pretest posttest by subject dengan sampel sebanyak 72 siswa, bertujuan untuk mempelajari (i) deskripsi hasil belajar matematika setelah diberi perlakuan kombinasi model pembelajaran kooperatif dan motivasi belajar, (ii) pengaruh linier kovariat self efficacy siswa terhadap hasil belajar matematika, dan (iii) faktor interaksi kombinasi model pembelajaran kooperatif (jigsaw, TAI dan STAD) dan motivasi belajar dengan mengontrol kedua faktor utama secara simultan mempunyai pengaruh terhadap hasil belajar matematika dengan memperhitungkan kovariat self efficacy siswa. Hasil analisis menggunakan Anakova menunjukkan bahwa (i) nilai rata-rata hasil belajar berfluktuasi pada masing-masing sel dalam mendukung hipotesis yang diajukan, (ii) kovariat self efficacy siswa mempunyai pengaruh positif yang signifikan terhadap hasil belajar matematika dengan kontribusi sebesar 0,310 satuan, dan dengan memperhitungkan kovariat self efficacy siswa, (iii) interaksi kombinasi model pembelajaran kooperatif dan motivasi belajar secara simultan dengan mengontrol kedua faktor utama mempunyai pengaruh yang tidak signifikan terhadap hasil belajar matematika
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
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
