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

Get PDFSafitri, Yulinar. 2018. Pembelajaran Materi Geometri Transformasi dengan Model Think Pair Share berbantuan Geogebra. Dr. Cut Morina Zubainur, S.Pd., M.Pd. (2) Mukhlis Hidayat, S.Pd.,M.KomKata Kunci: Hasil belajar, Motivasi, Think pair share, Geogebra.Hasil belajar dan motivasi belajar siswa pada materi geometri transformasi masih rendah, hal ini terjadi karena pemilihan model maupun media pembelajaran yang kurang tepat. Strategi yang diharapkan dapat meningkatkan hasil belajar dan motivasi belajar siswa yaitu melalui pembelajaran materi geometri transformasi dengan model Think Pair Share (TPS) berbantuan Geogebra. Penelitian ini bertujuan untuk mengetahui peningkatan hasil belajar siswa dan motivasi belajar siswa pada pembelajaran geometri transformasi dengan model TPS berbantuan Geogebra. Pendekatan dan jenis penelitian yang digunakan adalah pendekatan kuantitatif dengan desain One Group Pretest-posttest Design dan kuantitatif deskriptif. Populasi pada penelitian ini adalah seluruh siswa kels IX di SMP Negeri 1 Meureudu. Sampel penelitian dipilih secara random yaitu kelas IX-1 yang berjumlah 26 siswa. Data penelitian ini adalah hasil belajar dan motivasi belajar siswa. Pengumpulan data dilakukan dengan instrumen tes hasil belajar dan angket motivasi belajar. Hasil penelitian menunjukkan bahwa terdapat peningkatan hasil belajar siswa pada pembelajaran materi Geometri Transformasi dengan Model Think Pair Share berbantuan Geogebra. Hasil analisis data menunjukkann nilai t_hitung (8,11) > t_tabel (1,70814) sehingga H0 ditolak dan H_a diterima. Selanjutnya nilai rata-rata motivasi belajar siswa pada pembelajaran materi Geometri Transformasi dengan model think pair share berbantuan geogebra termasuk ke dalam kategori tinggi (74,16%)
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
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

PENGARUH CAMPURAN ARANG KAYU TERHADAP KARAKTERISTIK BRIKET LIMBAH DAUN CENGKEH
No full textRachmawati Dwi Yulinar. 2019. Pengaruh Campuran Arang Kayu terhadap
Karakteristik Briket Limbah Daun Cengkeh. Widi Widayat, S.T., M.T. Teknik
Mesin. Fakultas Teknik.
Limbah daun cengkeh sisa destilasi dan arang kayu memiliki potensi yang
cukup besar yang bisa dijadikan bahan baku briket. Penelitian ini bertujuan untuk
mengetahui pengaruh komposisi campuran antara daun cengkeh terhadap
karakteristik briket yang meliputi: uji proximate (nilai kalor, kadar air, kadar abu,
volatille matter, dan fixed carbon), densitas, stability, drop test, dan laju
pembakaran.
Variasi campuran arang kayu adalah 0%, 20%, dan 40% dan penambahan
perekat 15%. Daun cengkeh dikeringkan dahulu sekitar 5 jam, setelah itu bahan
baku tiap variasi dicampur dan dilakukan pembriketan. Briket yang sudah jadi
kemudian dilakukan pengujian dan dianalisis.
Penambahan arang berpengaruh terhadap karakteristik briket. Arang kayu
meningkatkan nilai kalor pada briket. Varian arang 40% memiliki nilai kalor 5335
kal/gr. Variasi campuran arang berpengaruh terhadap temperatur maksimal dan
sisa massa pada setiap 5 detik. Semakin banyak campuran arang pada briket
mengakibatkan lebih lama mencapai temperatur maksimal, lebih lama dalam
proses pengeringan dan devolatilization, akan tetapi lebih singkat pada proses
char combustio
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
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
