Perbandingan Kualitas Pot Hitam dan Softpot Terhadap Pertumbuhan Vegetatif Anggrek Dendrobium sonia ersakul
Full text linkThe aim of this research is to compare the quality of black pots and soft pots on the vegetative growth of the Dendrobium sonia ersakul orchid. The method used was perfect randomization with one treatment, namely black pot and soft pot. Data analysis used a two-way t-test at the 5% level. The results of the research show that using different types of pots can make a real difference to the parameters of plant height, length of shoots and number of new roots, but does not make a real difference to root length. The difference in the quality of the two pots is influenced by the level of water supply to the plant, plant drainage, and the level of oxygen absorption in the roots.

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
Pengembangan Desain Batik berkonsep Biologi dengan Pewarna Alami untuk Pemberdayaan Pembatik Limbangan: Development of Batik Design with a Biological Concept with Natural Dyes to Empower Limbangan Batik Makers
Full text linkBatik tema biologi menggunakan motif serta corak yang merupakan representatif dari bidang keilmuan biologi, seperti virus, amoeba, fertilisasi, dan lain-lain. Penggunaan pewarna alami untuk pewarnaan kain batik dapat memanfaatkan bagian-bagian tumbuhan seperti biji jalawe, kulit manggis, indigofera, kayu tingi, kayu mahoni, kayu secang, dan lain-lain. Tujuan pelaksanaan kegiatan ini, yaitu untuk mengembangkan desain batik tema biologi dengan pewarna alami sebagai pemberdayaan pembatik Limbangan. Kegiatan ini dilakukan melalui kolaborasi bersama Batik Linggo Limbangan dan masyarakat dengan jumlah peserta 15 orang serta menggunakan metode tutorial. Langkah pertama pengembangan desain batik, yaitu peserta diberi penjelasan oleh fasilitator tentang langkah-langkah pembuatan batik. Pada tahap kedua, peserta diajak untuk praktik langsung dengan langkah-langkah yang telah dijelaskan. Dari kegiatan ini menghasilkan 3 motif batik bertemakan biologi yaitu biofer (biologi fertilisasi), bioba (biologi amoeba), dan biovi (biologi virus). Kesimpulan dari kegiatan ini adalah masyarakat semakin teredukasi untuk melestarikan keragaman motif batik serta dapat memanfaatkan keanekaragaman flora yang ada di lingkungan sekitar sebagai pewarna alami batik
