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
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
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
Efektivitas Hormon Paclobutrazol dan Manipulasi Poliploidi Terhadap Optimalisasi Tanaman Porang (Amorphophallus oncophyllus) Sebagai Sumber Pangan Fungsional
Full text linkTanaman porang (Amorphophallus oncophyllus) telah diidentifikasi sebagai sumber pangan fungsional yang potensial, namun pengoptimalannya memerlukan upaya dalam peningkatan produktivitas dan kualitas. Penelitian ini bertujuan untuk mengevaluasi efektivitas hormon paclobutrazol dan manipulasi poliploidi menggunakan kolkisin terhadap pertumbuhan dan hasil tanaman porang. Penelitian dilakukan di wilayah Desa Jedong Kecamatan Wagir Kabupaten Malang.
Penelitian dilakukan dengan Rancangan Acak Kelompok Faktorial (RAKF) yang melibatkan dua faktor perlakuan, yaitu dosis hormon paclobutrazol (0 ppm, 75 ppm, 100 ppm, 125 ppm) dan dosis larutan kolkisin (0 ppm, 2 ppm, 4 ppm, 6 ppm) sehingga diperoleh 16 kombinasi perlakuan dan diulang sebanyak tiga kali. Hasil dari penelitian menunjukkan bahwa pemberian kolkisin sebanyak 4 ppm memberikan hasil terbaik pada fase vegetatif, sementara dosis 2 ppm lebih optimal pada fase generatif. Hormon paclobutrazol dengan dosis 75 ppm meningkatkan pertumbuhan vegetatif, sedangkan perlakuan tanpa paclobutrazol memberikan hasil terbaik pada fase generatif. Kombinasi hormon paclobutrazol 75 ppm dan kolkisin 4 ppm adalah yang paling efektif dalam meningkatkan pertumbuhan vegetatif, sedangkan kombinasi tanpa paclobutrazol dan kolkisin 2 ppm memberikan hasil terbaik pada fase generatif, yaitu berat umbi (1.086 gram), berat basah brangkasan (390,12 gram), dan berat basah bulbil (8,03 gram). Dosis kolkisin yang lebih tinggi dari 4 ppm dan hormon paclobutrazol lebih dari 75 ppm dapat menyebabkan penurunan pertumbuhan dan hasil tanaman porang. Penggunaan kolkisin yang lebih tinggi dari 3 ppm juga menurunkan produktivitas tanaman meskipun menyebabkan pertumbuhan lebih pendek.Yayasan Bina Patria Nusantar

Pengaruh Media Tanam dan Pemberian Pupuk Npk Phonska Terhadap Pertumbuhan Tumbuhan Kailan (Brassica Oleoraceae)
Full text linkKailan (Brassica oleoraceae var acephala) atau biasa yang dikenal dengan nama Kale merupakan tumbuhan sayur dalam famili kubis-kubisan, sayuran kailan sendiri datang ke Indonesia pada abad 17 yang dating dari China. Tumbuhan kailan memiliki daun berwarna hijau dan tebal, berbatang tebal, serta mempunyai bunga dengan ukuran kecil dibagian atas seperti pada tumbuhan brokoli, Sayur Kailan pada masyarakat sudah begitu dekat pada masyarakat karena kalian merupakan sumber vitamin (Irfan Afandi, 2019).. Tujuan penelitian ini untuk mengetahui : (1) media tanam manakah yang baik bagi pertumbuhan kailan (2) bagaimana pengaruh pemberian pupuk NPK Phonska pada pertumbuhan Kailan, (3) ada tidaknya interaksi antara media tanam dan pemberian pupuk NPK Phonska dengan takaran yang bervariasi pada pertumbuhan tumbuhan sayur Kailan. Penelitian dilaksanakan di Lab Lapangan Terpadu Fakultas Pertanian Universitas Tribhuwana Tunggadewi Malang, Jalan Telaga Warna, Kelurahan Tlogomas, Kecamatan Lowokwaru, Malang. Yaitu selama bulan Oktober-Desember 2017. Penelitian ini menggunakan RAK (Rancangan acak kelompok) faktorial, jarak tanam 40x40 cm dengan dua faktor: yakni media tanam (T): tanah + pupuk kandang yang terdiri atas dua perlakuan dan pemberian pupuk NPK Phonska (P) dengan takaran yang bervariasi yang terdiri dari 6 taraf perlakuan. Penganalisisan data menerapkan analisis ragam (uji F) pada taraf 5% ketika dihasilkan keberpengaruhan nyata selanjutnya dilakukan uji BNT 5%.
Penelitian ini menunjukkan hasil yaitu tidak didapati interaksi antara media dan dosis NPK Phonska pada pertumbuhan dan hasil tumbuhan kailan, 2.Pertumbuhan kailan terbaik diperoleh pada media tanam campuran dengan pupuk kandang (organik) ditinjau pada hasil luas daun terhadap luas daun umur 28 hst sebesar 42,65 cm2, serta hasil berat basah tumbuhan sebesar 26,02 g pada umur 35 hst, dan 3. Hasil tumbuhan kailan terbaik diperoleh pada pemberian dosis pupuk NPK Phonska 400 kg (4,72 g/tumbuhan) pada umur 28 hst, sedangkan pertumbuhan terbaik dijumpai pada jumlah daun (8,17 helai) da luas daun sebesar 168,05 cm2 pada umur 35 hst.Yayasan Bina Patria Nusantar
