    The purpose of this research is to observe the dosage of natrium, phospor and kalium fertilizer and the concentration of Atonic Growth Regulators appropriate for the growth and production of mustard greens (Brassica juncea, L) is good, and interaction of both factors. This research was conducted in Batumbulan Asli Village, Babussalam Sub-district, Southeast Aceh Regency with its height ± 220 m above sea. This research done in December 2016-January 2017, using Random Block Design (RBD) Factorial, which consists of 2 (two) factors. The first factor is the dosage of fertilizer (N) consisting of 3 levels, N1 = 0.50 gr /plot, N2 = 1 gr/ plot and N3 = 1.5 gr / plot. The second factor is the concentration of Atonic Growth Atonic Growth Regulator (A) consisting of 3 levels, A1 = 0.50 cc / l water, A2 = 1 cc /l water and A3 = 1.5 cc /l water. Parameters observed were plant height, number of leaves and leaf area. The results reported that fertilizers did not significantly affect the growth, but there was a tendency where the fertilizers and growth regulator fertilizer could increase the growth of mustard plan

    Optimalisasi Produksi Kedelai Varietas Anjasmoro Dengan Manipulasi Arah Baris Dan Gulma

    Penelitian ini menggunakan Rancangan Acak Kelompok yang tediri dari dua faktor. Faktor pertama manipulasi arah baris tanaman : utara-selatan, timur laut-barat daya, timur-barat, tenggara-barat laut. Faktor ke dua waktu penyiangan gulma : penyiangan terus menerus, 14 hari setelah tanam, 28 hari setelah tanam, (14 dan 28) hari setelah tanam. Enam belas kombinasi perlakuan diulang sebanyak tiga kali. Hasil penelitian menunjukkan manipulasi arah baris tidak memberikan pengaruh terhadap seluruh parameter pengamatan. Pada pengamatan hari ke 28 dan hari ke 42 setelah tanam tinggi tanaman tertinggi terdapat pada perlakuan penyiangan gulma terus menerus dan penyiangan gulma (14 dan 28) hari setelah tanam. Umur berbunga dan panen tercepat tanaman kedelai terdapat pada perlakuan penyiangan gulma 14 hari setelah tanam. Berat biji per tanaman dan jumlah polong bernas per tanaman tertinggi terdapat pada perlakuan penyiangan gulma terus menerus dan penyiangan gulma (14 dan 28) hari setelah tanam

    Going Beyond Counting First Authors in Author Co-citation Analysis

    The 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

    “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 link
    We 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 link
    We 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

    We 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
