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
EVALUASI NUTRISI DAUN DAN PELEPAH SAWIT MELALUI FERMENTASI MENGGUNAKAN ASPERGILLUS NIGER DENGAN PENAMBAHAN BERBAGAI SUMBER KARBOHIDRAT TERLARUT
No full textEVALUASI NUTRISI DAUN DAN PELEPAH SAWIT MELALUI FERMENTASI MENGGUNAKAN Aspergillus niger DENGAN PENAMBAHAN BERBAGAI SUMBER KARBOHIDRAT TERLARUTOlehMuhammad ResthuABSTRAKKekurangan pakan terutama hijauan makanan ternak (HMT) baik kualitas maupun kuantitas menjadi kendala utama dalam peningkatan produktivitas ternak ruminansia, sehingga perlu adanya sumber pakan alternatif. Salah satu komoditi terbesar di Indonesia adalah perkebunan kelapa sawit yang menghasilkan limbah yang dapat dimanfaatkan sebagai pakan ternak yaitu daun dan pelepah sawit. Tujuan penelitian ini untuk mengevaluasi nutrisi daun dan pelepah sawit melalui proses fermentasi menggunakan Aspergillus niger dengan penambahan berbagai sumber karbohidrat terlarut. Percobaan ini dilakukan di Jurusan Peternakan, Fakultas Pertanian, Universitas Syiah Kuala, Banda Aceh selama dua bulan dari bulan Oktober s/d November 2014. Materi yang digunakan dalam penelitian ini adalah Aspergillus niger dan berbagai sumber karbohidrat terlarut. Percobaan yang dilakukan adalah percobaan eksperimen, menggunakan Rancangan Acak Lengkap (RAL) yang terdiri atas lima (5) perlakuan (FK: kontrol, FTS: tepung sagu, FTB: tepung beras, FDH: dedak halus dan FJG: jagung giling). Masing-masing perlakuan diulang sebanyak tiga (3) kali, sehingga diperoleh 15 unit percobaan. Parameter yang diukur pada penelitian ini adalah bahan kering, protein kasar, serat kasar, dan abu. Hasil penelitian menunjukkan, penambahan berbagai karbohidrat terlarut pada media fermentasi menggunakan Aspergillus niger tidak berpengaruh nyata (P>0,05) terhadap bahan kering substrat, namun berpengaruh nyata (
INDUKSI HORMON OKSITOSIN DALAM UPAYA PENINGKATAN PRODUKSI SUSU, KOMPOSISI SUSU, DAN RESPON FISIOLOGIS PADA KAMBING PERANAKAN ETAWAH (PE)
Get PDFRINGKASANMUHAMMAD RESTHU. Induksi Hormon Oksitosin dalam Upaya Peningkatan Produksi Susu, Komposisi Susu, dan Respon Fisiologis pada Kambing Peranakan Etawah (PE). DZARNISA, SRI WAHYUNIIndonesia merupakan negara agraris yang memiliki potensi dalam pengembangan sektor pertanian terutama sub sektor peternakan. Sub sektor peternakan berpotensi sebagai penunjang perekonomian masyarakat, dan menyumbangkan perkembangan perekonomian nasional. Kambing adalah ternak yang banyak dipelihara oleh masyarakat. Jenis kambing Peranakan Etawah (PE) yang dipelihara bertujuan untuk produksi susu. Selama ini banyak upaya dalam peningkatan produksi susu dan komposisi susu salah satunya dengan induksi hormon oksitosin. Salah satu fungsi hormon oksitosin yaitu merangsang sel-sel mioepitel yang mengelilingi alveoli untuk mengeluarkan susu. Penelitian ini bertujuan untuk melihat peningkatan produksi susu, komposisi susu dan respon fisiologis kambing PE setelah diinduksi dengan hormon oksitosin. Jenis penelitian ini adalah eksperimental dengan model post test only control group design. Pengolahan data menggunakan uji t tidak berpasangan untuk membandingkan kelompok kontrol dan perlakuan. Kemudian dilanjutkan dengan uji regresi variable dummy. Parameter yang diukur diantaranya produksi susu (ml), detak jantung (kali/menit), frekuensi pernafasan (kali/menit), kadar bahan kering tanpa lemak (BKTL) (%), kadar lemak (%), kadar protein (%), kadar laktosa (%), dan densitas (g/ml). Materi penelitian yaitu kambing PE yang sedang dalam masa laktasi sebanyak 18 ekor, dikelompokkan menjadi kelompok kontrol dan kelompok perlakuan. Penelitian ini dilaksanakan mulai dari Desember 2018 sampai Februari 2019. Hasil uji statistik menunjukkan bahwa induksi hormon oksitosin tidak berpengaruh (P>0,05) terhadap produksi susu kambing PE pada pagi dan sore hari. Menurut uji statistik, induksi hormon oksitosin terhadap detak jantung pagi kambing PE berpengaruh sangat nyata (P0,05). Begitu pula uji statistik, induksi oksitosin tidak berpengaruh nyata (P>0,05) terhadap frekuensi pernafasan kambing PE pagi dan sore hari. Uji statistik memperlihatkan kadar BKTL, kadar protein dan kadar laktosa tidak berpengaruh nyata (P>0,05). Sementara pada kadar lemak pagi berpengaruh sangat nyata (
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
