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
UPAYA PENINGKATAN HASIL TANAMAN NENAS DI LAHAN GAMBUT
Full text linkPenelitian ini bertujuan untuk mengetahui upaya yang dapat dilakukan dalam peningkatan produksi tanaman nenas di lahan gambut. Upaya tersebut adalah dengan mengkombinasikan antara jarak tanam danaplikasi pupuk N, P dan K. Penelitian menggunakan metode Analisis antar lokasi dengan Rancangan Acak Kelompok Lengkap yang terdiri dari dua faktor yaitu faktor jarak tanam dan pemupukan N, P dan K. Perlakuan yang dimaksud adalah (1). Faktor jarak tanam dengan 2 aras yaitu : J1 = 60 cm x 60 cm dan J2 = 60 cm x 90 cm. (2). Faktor pemupukan terdiri dari 3 aras yaitu P0 = Tanpa pemupukan, P1 = 175 kg urea +125 kg SP-36 + 200 Kg KCl per Ha,P2 =350 kg urea + 250 kg SP-36 + 400 kg KCl per Ha dan P3 = 525 kg urea + 375 kg SP-36 +600 kg KCl per Ha. Masing-masing kombinasi perlakuan diulang sebanyak 3 kali. Pengamatan dilakukan terhadap Serapan Hara K pada Jaringan Tanaman, Bobot Kering Tajuk, Indeks Panen, Berat Buah segar. Data yang diperoleh dianalisis dengan analisis varian pada taraf 5%. Jika memberikan pengaruh yang nyata, analisis dilanjutkan dengan uji jarak berganda Duncan (DMRT) taraf 5%. Hasil penelitian menunjukkan bahwa takaran pemupukan pada perlakuan P2 (350kg urea + 250 kg Sp-36 + 400 kgKCl) per ha merupakan upaya yang terbaik dalam peningkatan hasil tanaman nenas di lahan gambut. Terdapat interaksi antara jarak tanam dan pemupukan terhadap bobot segar buah dan Indeks panen. Kata kunci : nenas, gambu
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
Effect of Use of Swallow Dirt on the Growth and Yield of Peanut Soils on Ultisol Soils
No full textThis study aims to determine the best dosage for growth and yield of peanut plants on ultisol soil. This research was carried out on the experimental field of the Faculty of Agriculture, Tanjungpura University of Pontianak which took place September 16, 2018 to December 20, 2018. The method used was a Complete Randomized Design Test (CRD) consisting of 6 treatments, 4 replications, and 4 samples. Giving various types of swallow droppings including a1 = 269 g / polybag, a2 = 514 g / polybag, a3 = 759 g / polybag, a4 = 1,004 g / polybag, a5 = 1,249 g / polybag and a6 = 1,494 g / polybag. Observations were made on plant height, number of pods of plants, dry weight of plants, dry weight of seeds. Based on the results of the study it can be concluded that the administration of swallow feces with a dose of 1,249 g / polybag or the equivalent of 16% organic matter gives the best results for the growth and yield of peanut plants on ultisol soil. Keywords: peanuts, swallow droppings, ultisol soil
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
