Going Beyond Counting First Authors in Author Co-citation Analysis
Get PDFThe 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
Get PDF“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
Get PDFWe 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
Pengaruh Penambahan Puree Belimbing Wuluh (Averrhoa bilimbi, L.) terhadap Karakteristik Fruit Leather Kulit dan Daging Buah Naga
No full textFruit leather merupakan makanan ringan yang berbentuk seperti lembaran yang tipis dari proses pengeringan. Penelitian ini bertujuan untuk menganalisis interaksi penambahan belimbing wuluh dan variasi kulit dengan daging buah naga terhadap karakteristik fruit leather, mendapatkan formulasi terbaik dari penambahan belimbing wuluh dan variasi kulit dengan daging buah naga terhadap fruit leather yang dihasilkan, dan menganalisis kelayakan usaha fruit leather. Penelitian ini dilakukan dengan menggunakan metode Rancangan Acak Lengkap Faktorial yang mana terdiri atas 2 faktor dengan 3 kali pengulangan dengan variasi belimbing wuluh dengan kulit dan daging buah naga. Data yang didapatkan dianalisis secara statistik menggunakan Analysis of Variance (ANOVA) jika berbeda nyata maka dilanjutkan dengan uji Duncan’s New Multiple Range Test (DNMR) pada taraf 5%. Interaksi penambahan tingkat konsentrasi kombinasi kulit dan daging buah naga merah (Hylocereceus polyrhizus) dengan penambahan puree belimbing wuluh (Averrhoa bilimbi, L.) berpengaruh nyata pada kadar serat dan nilai tekstur fruit leather. Sedangkan pada kadar air, kadar abu, pH, total asam, vitamin C, total gula, betasianin, dan antioksidan berpengaruh tidak nyata. Kombinasi perlakuan terbaik yaitu A1B3 (Kulit buah naga : Daging buah naga (KBN: DBN (1:1)) + belimbing wuluh (BW (12%)) memberikan mutu terbaik dari kombinasi perlakuan lainnya yang ditinjau dari kadar serat 6,88 % dan tekstur 25,55 N/mm. Analisis kelayakan usaha fruit leather yaitu BCR memiliki nilai 1,31
Dispelling the Myths Behind First-author Citation Counts
Get PDFWe 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
Book of Gambir Pengolahan, Komponen dan Manfaat
No full textGambir merupakan ekstrak kering dari daun serta cabang tanaman Uncaria gambir. Gambir secara tradisional digunakan sebagai obatobatan tradisional seperti sakit perut dan sakit tenggorokan. Gambir dapat digunakan sebagai obat tradisional, yaitu obat diare, obat batuk dan sebagai pengawet makanan. Kabupaten Pesisir Selatan dan Lima Puluh Kota merupakan daerah sentra produksi gambir Sumatra Barat. Buku ini akan membahas mengenai pengolahan gambir pada kedua daerah tersebut serta informasi lainnya tentang gambir. Sumatera Barat merupakan salah satu sentra produksi gambir, dimana sebagai pemasok terbesar gambir , yaitu Lima Puluh Kota dan Pesisir Selatan (Dinas Perkebunan Sumbar, 2013). Pengolahan gambir pada dasarnya meliputi pemanenan, pengukusan (steaming), pengempaan untuk mengeluarkan ekstrak, penggumpalan, penirisan dan pengeringan. Pada tahapan rangkaian proses gambir inilah yang akan menentukan kualitas gambir yang dihasilkan. Permasalahan yang ditemui bahwa di beberapa daerah Sumatra Barat adalahnya bervariasinya kualitas gambir yang dihasilkan. Hal ini harus mendapatkan perhatian khusus mengingat komponen utama gambir adalah senyawa catechin. Gambir dengan nama latin Uncaria gambir merupakan tanaman yang termasuk ke dalam family Rubiaceae. Rubiaceae merupakan kelompok tanaman yang banyak menghasilkan komponen bioaktif. Komponen bioaktif dari tanaman kelompok Rubiaceae ini telah banyak dimanfaatkan untuk dunia farmasi. Berikut adalah komponen bioaktif dari family Rubiaceae
