    Muhammad Rais Ardy. 2021. “Survei Penyakit Busuk Pangkal Batang Kelapa Sawit Ganoderma boninense di Kebun Bah Lias PT.PP. London”. Di bawah bimbingan Lisnawita dan Irda Safni. Penyakit busuk pangkal batang (BPB) yang disebabkan oleh G.boninense merupakan salah satu penyakit utama pada tanaman kelapa sawit di Indonesia, khususnya di Sumatera Utara karena mengakibatkan penurunan hasil dan kematian tanaman. Penelitian ini bertujuan untuk mengetahui penyebaran penyakit BPB di kebun Bah Lias PT.PP. London Sumatra Indonesia, Tbk. Penelitian menggunakan metode survei purposive random sampling dengan pengamatan pada 2 Divisi yaitu Divisi 1 dan Divisi 2, masing-masing 3 blok dengan sampel 10% dari populasi tanaman. Hasil penelitian menunjukkan persentase kejadian dan keparahan penyakit tertinggi terdapat pada lokasi Divisi 1 dengan kode blok 3112000 yaitu masing-masing 21.43% dan 13.35%. dan terendah terdapat pada lokasi Divisi 2 kode blok 7111013 yaitu 8,33% dan 5.67%.Muhammad Rais Ardy. 2021 " Survey of Basal Stem Rot Disease Ganoderma boninense in Bah Lias Plantation PT.PP. London". Supervised by Lisnawita and Irda Safni. Basal Stem Rot (BSR) caused by G.boninense is one common diseases in oil palm plants in Indonesia, especially in North Sumatra,because it reduces the yield and plants die.This study was aimeds to determine the spread of BSR in Bah Lias plantation of PT.PP. London Sumatra Indonesia, Tbk . This research was using purposive random sampling survey method with observation of 2 Divisions, namely Division 1 and Division 2, each of 3 blocks with a sampel of 10% of the plant population. The results showed that the highest percentage of disease incidence and disease severity was at the location of Division 1 with block code 3112000, namely 21.43% and 13.35%, respectively. and the lowest was in the location of Division 2 code block 7111013, namely 8.33% and 5.67%.47 HalamanSkripsi Sarjan

    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

    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

    Get PDF
    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

    koamabayili/VECTRON-author-checklist: VECTRON author checklist

    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
