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
Problem Based Learning pada Pembelajaran Literasi Matematika: Studi Quasi Eksperimental pada Mahasiswa PGSD
No full textLiterasi matematika adalah kemampuan individu dalam merumuskan, menerapkan, dan menafsirkan matematika pada berbagai konteks. Tujuan penelitian ini untuk menjelaskan apakah terdapat pengaruh model problem based learning terhadap kemampuan literasi matematika mahasiswa PGSD di Universitas PGRI Adi Buana Surabaya. Penelitian ini merupakan penelitian quasi eksperimen. Populasi dalam penelitian ini mahasiswa PGSD angkatan 2018. Penelitian ini menggunakan simple random sampling yang kemudian terpilih kelas 2018 E sebagai kelas eksperimen dan 2018 F sebagai kelas kontrol. Metode yang digunakan adalah metode tes. Instrumen yang digunakan adalah soal tes yang diadaptasi dari soal PISA. Hasil penelitian menunjukkan bahwa terdapat pengaruh signifikan pada model pembelajaran problem based learning terhadap kemampuan literasi matematika mahasiswa PGSD
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
PENGEMBANGAN PERANGKAT PEMBELAJARAN TEAMS GAMES TOURNAMENT (TGT) DENGAN PENDEKATAN SAINTIFIK PADA MATERI OPERASI ALJABAR SMP TAHUN PELAJARAN 2014/2015
Full text linkPenelitian ini bertujuan untuk: (1) mendeskripsikan pengembangan perangkat pembelajaran matematika dengan model TGT dengan pendekatan saintifik pada materi operasi aljabar yang valid dan praktis; (2) mengetahui keefektifan pembelajaran menggunakan perangkat pembelajaran Matematika dengan model TGT dengan pendekatan saintifik pada materi operasi aljabar
Jenis penelitian ini adalah Research and Development. Pengembangan perangkat pembelajaran dilakukan dengan menggunakan model 4-D Thiagarajan, dkk, namun peneliti hanya menempuh 3D, yang terdiri atas define, design, dan develop. Perangkat pembelajaran yang dikembangkan adalah RPP, LKS, dan tes kemampuan pemecahan masalah. Subjek ujicoba penelitian ini dilakukan di kelas VIII SMPN 2 Pemalang, SMPN 4 Taman, dan SMPN 1 Pemalang. Populasi pada penelitian ini adalah seluruh siswa kelas VIII SMP Negeri se-Kabupaten Pemalang Tahun Pelajaran 2014/2015. Sampel dalam penelitian ini diperoleh dengan menggunakan teknik stratified cluster random sampling. Sampel dalam penelitian ini terdiri atas 218 siswa dengan rincian 108 siswa pada kelas yang dikenai model TGT dengan pendekatan saintifik dan 110 siswa pada kelas yang dikenai model klasikal dengan pendekatan saintifik. Analisis data untuk menilai kevalidan perangkat pembelajaran dilakukan oleh 5 validator menggunakan instrumen lembar validasi perangkat pembelajaran. Kepraktisan perangkat dinilai menggunakan lembar angket respons siswa, angket respons guru, dan lembar pengamatan keterlaksanaan RPP dalam pembelajaran. Keefektifan dinilai menggunakan lembar pengamatan aktivitas siswa dan analisis hasil tes kemampuan pemecahan masalah diuji menggunakan uji rerata dan uji proporsi.
Hasil validasi perangkat pembelajaran dinyatakan valid menurut ahli karena diperoleh rata-rata validasi dalam rentang skor antara 1–4, yaitu: RPP 3,32, LKS 3,42, dan tes kemampuan pemecahan masalah 3,44 dan telah memenuhi validitas isi, taraf kesukaran baik, daya pembeda baik, dan reliabel. Perangkat pembelajaran yang dikembangkan praktis, karena setelah diujicobakan diperoleh hasil: (1) adanya respons positif dari siswa; (2) adanya respons yang baik dari guru; (3) keterlaksanaan RPP dalam pembelajaran pada kategori baik. Pembelajaran efektif pada kelas eksperimen karena setelah diujicobakan diperoleh hasil: (1) aktivitas siswa kelas uji coba berkategori baik; (2) rata-rata kemampuan pemecahan masalah siswa kelas uji coba perangkat lebih baik dari kelas kontrol; (3) kemampuan pemecahan masalah siswa telah mencapai ketuntasan klasikal. Dapat disimpulkan bahwa pengembangan perangkat TGT dengan pendekatan saintifik memenuhi kriteria valid, praktis, dan pembelajarannya efektif.

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
