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
Mulsa Organik: Pengaruhnya terhadap Lingkungan Mikro, Sifat Kimia Tanah dan Keragaan Cabai Merah di Tanah Vertisol Sukoharjo pada Musim Kemarau
Full text linkABSTRACTRed chilli is commercial crop and has high economic values. Experiments were conducted to improve red chilli’s cultivation technique, by applying organic mulches to increase plant growth and yield. The experiment was set up in a completely randomized block design with three replications to evaluate the effects of organic mulches on microclimate, soil chemical properties, red chilli growth and yield. Mulch treatment consisted of silver-black polyethylene plastic, rice straw, rice husk, corn litter and without mulch as a control. The application of organic mulches at the rate of 6 ton ha-1in the dry season increased soil temperature, soil moisture, cation exchange capacity, pH, C organic, soil organic matter, N total, K availability and C/N ratio. The application of organic mulches in dry season increased plant growth in terms of number of dichotome branches, leaf area, and dry weight of plant, net assimilation rate, relative growth rate, fruit length and better fruit yields. The highest production was achieved by rice straw, i.e, 1.29 kg fruit fresh weight per plant. Plant treated with organic mulches produced fruit per plot 18% greater than those treated with plastic polyethylene.Keywords: cation exchange capacity, leaf area, growth, yieldABSTRAKCabai merah merupakan tanaman komersial dan memiliki nilai ekonomi yang tinggi. Percobaan dilakukan untuk memperbaiki teknik budidaya cabai merah dengan pengaplikasian mulsa organik untuk meningkatkan pertumbuhan dan hasil tanaman. Percobaan disusun dalam rancangan kelompok lengkap teracak dengan 3 ulangan untuk mengevaluasi pengaruh mulsa organik terhadap iklim mikro, sifat kimia tanah, pertumbuhan dan hasil cabai merah. Mulsa yang digunakan adalah plastik polietilen hitam perak, jerami padi, sekam padi, serasah jagung dan tanpa gulma sebagai kontrol. Aplikasi mulsa organik adalah sebesar 6 ton/ha pada musim kering meningkatkan suhu tanah, kelembaban tanah, kapasitas tukar kation, pH, C organik, bahan organik tanah, N total, ketersediaan K dan C/N rasio. Aplikasi mulsa organik pada musim kering meningkatkan pertumbuhan tanaman dilihat dari jumlah cabang dikotomus, luas area daun, bobot kering tanaman laju asimilasi bersih, laju pertumbuhan relatif, panjang buah dan hasil buah yang lebih baik. Produksi tertinggi diperoleh pada perlakuan mulsa organik jerami padi dengan bobot buah segar, sekitar 1.29 kg per tanaman. Tanaman dengan perlakuan mulsa organik meng hasilkan buah per plot 18% lebih besar dibandingkan tanaman dengan perlakuan mulsa plastik polietilen hitam perak.Kata kunci : kapasitas tukar kation, area daun, pertumbuhan, hasi
