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 Substitusi Tepung Beras Ketan dengan Tepung Umbi Talas Bogor (Colocasia esculenta L Schoott) Terhadap Kualitas Dodol Susu Ditinjau dari Kualitas Fisik dan Kimia
No full textPengambilan data penelitian dilaksanakan 27 Januari 2016 sampai 29 Februari 2016 di Laboratorium Fisiko Kimia Bagian Teknologi Hasil Ternak Fakultas Peternakan, Universitas Brawijaya. Tujuan penelitian adalah mengetahui pengaruh substitusi tepung beras ketan dengan tepung umbi talas bogor terhadap peningkatan kualitas akhir produk dodol susu yang meliputi kualitas fisik (tekstur) maupun kualitas kimia (lemak, gula total dan gula reduksi). Penelitian diharapkan dapat meningkatkan kualitas produk akhir dodol susu berdasarkan sifat fisik (tekstur) maupun kimia (lemak, gula total dan gula reduksi) dengan menentukan level konsentrasi substitusi tepung umbi talas bogor terhadap tepung beras ketan. Materi penelitian ini adalah dodol susu yang dibuat dari susu segar yang dibeli dari Koperasi Mitra Bhakti Makmur Junrejo – Malang. Bahan lain yang digunakan adalah gula dan tepung beras ketan komersil yang diperoleh dari pasar swalayan, serta tepung umbi talas bogor yang dibuat dengan menggiling umbi talas dengan ukuran 80 mesh. Peralatan yang digunakan untuk proses pembuatan dodol susu meliputi wajan, loyang atau cetakan, pengaduk kayu, gelas, soxlet dan kompor gas. Metode penelitian menggunakan percobaan laboratorium dengan rancangan acak lengkap yang terdiri dari 5 perlakuan dan 4 ulangan. Perlakuan berupa viii substitusi tepung beras ketan dengan tepung umbi talas bogor yang diberikan pada produk dodol susu meliputi P0 (100% tepung beras ketan dan tanpa tepung umbi talas bogor), P1 (75% tepung beras ketan dan 25% tepung umbi talas bogor), P2 (50% tepung beras ketan dan 50% tepung umbi talas bogor), P3 (75% tepung beras ketan dan 25% tepung umbi talas bogor) dan P4 (tanpa tepung beras ketan dan 100% tepung umbi talas bogor). Variabel yang diuji meliputi tekstur, kadar lemak, gula total dan gula reduksi. Data yang diperoleh kemudian dianalisis ragam dan apabila terdapat perbedaan diantara perlakuan, maka dilanjutkan dengan Uji Jarak Berganda Duncan’s (UJBD). Hasil penelitian ini didapatkan bahwa terdapat pengaruh yang sangat nyata (P<0,01) substitusi tepung beras ketan dengan tepung umbi talas bogor terhadap gula reduksi dodol susu dengan gula reduksi terendah pada P2 (16,66%), serta berpengaruh nyata (P<0,05) terhadap kadar lemak dodol susu dengan kandungan lemak tertinggi sekitar 13,77% (P4), namun tidak berpengaruh nyata terhadap gula total dan tekstur dodol susu. Kesimpulan penelitian menunjukkan bahwa substitusi tepung umbi talas bogor terhadap tepung beras ketan mampu meningkatkan kualitas produk dodol susu yang dihasilkan, terutama pada peningkatan tekstur, kadar lemak dan penurunan gula reduksi. Penggunaan tepung umbi talas bogor 100% menghasilkan produk dengan tekstur dan kadar lemak tertinggi yakni 10,12 N dan 3,44%. Penurunan gula reduksi secara maksimal terdapat pada dodol susu dengan penggunaan tepung umbi talas bogor dan tepung beras ketan yang sama (50%:50%), namun perlakuan yang diberikan tidak memberikan peningkatan signifikan terhadap kualitas dodol susu berdasarkan kadar gula yang terkandung, dikarenakan adanya pengaruh pemanasan dalam proses pemasakan sehingga mempengaruhi kadar gula total yang terkandung
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

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
