    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

    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

    Efektifitas Pemanfaatan Pakan Sapi Potong dengan Intervensi Konsentrat Berbasis Ubi Kayu pada Sistem Pertanian Lahan Kering di Desa Kucur Kecamatan Dau Kabupaten Malang

    Penelitian ini bertujuan untuk mengetahui efektifitas pemanfaatan pakan yang tersedia dengan intervensi pakan konsentrat agar sesuai dengan kondisi di wilayah lahan kering Desa Kucur, Kecamatan Dau, Kabupaten Malang pada bulan Januari hingga Juni 2019. Metode yang digunakan adalah survei dan percobaan, dimana percobaan dilakukan dengan melakukan intervensi perlakuan pakan yang melibatkan 50 orang petani peternak di Desa Kucur yang dipilih secara purposive sampling, serta analisa kuantitas dan kualitas pakan hijauan yang diberikan. Metode intervensi meliputi pemberian pakan sebanyak 2% BK bobot badan untuk konsentrat berbasis ubi kayu (P1), konsentrat pabrikan lokal (P2), dan konsentrat berbasis bahan lokal lainnya (P3 dan P4), serta pemberian wheat pollard sebanyak 1 kg/hari (P0/kontrol). Variabel yang diamati meliputi profil petani peternak, manajemen pakan ternak, performans ternak, serta kuantitas dan kualitas sumber daya hijauan. Metode penelitian untuk percobaan dilakukan dengan rancangan acak kelompok dan dianalisis menggunakan analisis peragam (ANCOVA). Hasil penelitian menunjukkan bahwa profil petani peternak sebagian besar bergerak di penggemukan sapi potong dengan pengalaman diatas 10 tahun. Manajemen pakan peternak masih tradisional dan sederhana. Terdapat 7 jenis hijauan pakan dengan rumput kolonjono sebagai hijauan yang paling sering digunakan. Produksi hijauan pakan terbesar ditunjukkan oleh rumput teki dengan produksi BK sebesar 878,04 ton/tahun. Performans ternak dengan PBBH tertinggi ditunjukkan oleh P1, yaitu sebesar 1,04 kg/hari. Hasil aspek ekonomi, nilai FC dan FCOG terrendah ditunjukkan P0, yaitu Rp. 11.169 per hari dan Rp. 16.685 per kg. Nilai IOFC harian serta total terbesar ditunjukkan P1, yaitu berturut-turut sebesar Rp. 26.525 per hari, dan Rp. 1.207.943. Disimpulkan bahwa dengan pola ketersediaan pakan hijauan yang bervariasi dan berfluktuatif, juga dengan aspek sosial masyarakat di wilayah lahan kering Desa Kucur, didapatkan bahwa perlakuan P1 sebagai pemberian konsentrat berbasis ubi kayu menunjukkan hasil yang paling efektif dan dapat diadopsi oleh peternak

    This study aims to determine the effect of interaction and influence main compost of water hyacinth and NPK 16:16:16 on growth and Batak onion production. The research has been carried out in the garden Experiment at the Faculty of Agriculture, Riau Islamic University, Jalan Kaharuddin Nasution KM. 11, No. 113, Air Cold Village, Bukit Raya District, Pekanbaru City, Riau. And lasts for 4 months, starting from March - June 2020. This study used a factorial Completely Randomized Design (CRD) 4 x 4 which consists of 2 factors and 3 replications. The first factor is compost Water hyacinth consists of 4 levels, namely 0, 1, 2, 3 kg / plot. The second factor is NPK 16:16:16 consists of 4 levels, namely 0, 15, 30, 45 g / plot. Observed parameters is the number of leaves (strands), plant height (cm), number of tubers, tuber girth (cm), economic weight (g) and tuber weight per plot (g). Data from the observations of each treatment were analyzed statistically and followed by further tests of differences Real Honest (BNJ) at the 5% level. The results showed that the interaction effect of water hyacinth compost and NPK 16:16:16 had a significant effect on the quantity parameter leaf, economic weight and tuber weight per plot. Where is the treatment combination best at the dose of water hyacinth compost 3 kg / plot and NPK 16:16:16 45 g / plot (K3N3). The main effect of water hyacinth compost was significant on height parameters plant, tuber number, tuber convolution and tuber weight per plot. Where is the treatment best water hyacinth compost dose of 3 kg / plot (K3. Main effect of NPK 16:16:16 is significant for the parameters of plant height and number of tubers. Where the best treatment at a dose of NPK 16:16:16 45 g / plot (N3)
