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
Lama Perendaman Benih Sawi Hijau (Brassica rapa var. parachinensis) Dalam Larutan Mikroorganisme Lokal (MoL) Bonggol Pisang Kepok (Musa paradisiaca L.) Terhadap Viabilitas Benih
Full text linkTanaman sawi hijau merupakan salah satu tanaman sayur-sayuran yang bernilai ekonomis tinggi, sehingga diperlukan suatu perlakuan teknologi budidaya agar produksi tanaman sawi hijau tidak menurun. Untuk mengatasi hal tersebut diperlukan penggunaan benih yang berkualitas melalui peningkatan viabilitas benih yand diintegrasikan dengan agen hayati yaitu mikroorganisme lokal dari bonggol pisang. Tujuannya untuk mencegah kerusakan benih akibat adanya fungi atau cendawan, dan untuk mematahkan dormansi pada benih karena penyimpanan yang terlalu lama. Pada akhirnya dapat mempercepat perkecambahan benih sawi hijau. Penelitian ini dilakukan di kampung Pikhe, Wamena menggunakan rancangan acak lengkap (RAL) dengan 6 perlakuan dan 4 ulangan. Hasil penelitian membuktikan bahwa perendaman 2 jam, 4 jam, dan 6 jam menunjukkan potensi tumbuh benih dan daya berkecambah beni yang paling cepat. Namun demikian perendaman 6 jam paling direkomendasikan karena menunjukkan viabilitas benih yang paling baik. Sedangkan perendaman benih selama 8 jam dan 10 jam tidak menunjukkan viabilitas benih yang baik. Untuk itu, disarankan untuk melakukan perendaman benih sawi hijau selama 6 jam sebelum ditanam dan tidak direkomendasikan untuk melakukan perendaman lebih dari 10 jam karena hal ini dapat berpengaruh buruk terhadap viabilitas benih sawi hijau.

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
Identifikasi Jenis - Jenis Hama Yang Menginvasi Tanaman Sawi Hijau (Brassica rapa var. parachinensis) Di Lahan Pertanian Stkip Kristen Wamena
Full text linkTanaman Sawi Hijau merupakan salah satu komoditas hortikultura yang sangat cocok untuk dibudidayakan di Wamena. Hal ini disebabkan karena kondisi alam di Wamena yang sangat sesuai dengan syarat tumbuh tanaman sawi hijau yaitu membutuhkan ketersediaan air dan sinar matahari yang cukup. Kita ketahui bahwa Wamena merupakan wilayah dataran tinggi yang berbentuk lembah sehingga curah hujan sangat tinggi dan paparan sinar matahari juga cukup tinggi. Namun demikian, dalam pembudidayaan sawi hijau tidak terhindar dari adanya hama pengganggu yang dapat mengganggu pertumbuhan dan produkifitas tanaman sawi hijau di Wamena. Untuk itu, tujuan penelitian ini dilakukan adalah untuk mengidentifikasi jenis-jenis hama yang menginvasi (menyerang) tanaman sawi hijau selama fase vegetatif sampai pada masa panen di lahan pertanian STKIP Kristen Wamena. Penelitian ini dilakukan dengan cara survei (pengamatan) pada hama-hama yang menyerang tanaman sawi hijau selama pertumbuhannya (fase vegetatif) sampai pada masa panen. Hasil penelitian menunjukkan bahwa hama yang menginvasi tanaman sawi hijau dalam penelitian ini yang berhasil ditemukan hanya ada satu yaitu Ulat Tritip (Plutella xylostella L.). Hama ditemukan dalam bentuk larva instar 2 sampai dengan 3 ditandai dengan adanya kerusakan daun dan ciri-ciri bentuk larva Plutella xylostella L. secara morfologi.
