Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe 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

EFEKTIVITAS DAN KEAMANAN SALEP MINYAK LARVA BLACK SOLDIER FLY (Hermetia illucens L.) DALAM MENYEMBUHKAN LUKA SAYAT PADA MENCIT PUTIH (Mus musculus L.) JANTAN
Full text linkLuka merupakan suatu kondisi yang dapat mengakibatkan hilangnya integritas epitelial dari kulit sehingga fungsi kulit terganggu. Penggunaan sediaan topikal komersil dalam penyembuhan luka dapat menimbulkan banyak efek merugikan. Sehingga diperlukan bahan alami yang aman dan efektif dalam penyembuhan luka. Salah satunya adalah penggunaan minyak larva BSF yang dibuat menjadi sediaan salep. Penelitian ini bertujuan untuk menganalisis efektivitas dan keamanan dari pengaplikasian salep minyak larva BSF (Hermetia illucens L.) pada mencit. Luka yang dikondisikan adalah luka sayat dengan panjang 2 cm dan kedalama 2 mm. Desain percobaan yang diberikan adalah mencit dilukai tanpa perlakuan, kemudian sediaan salep yang dioleskan seperti salep gentamisin, basis salep, dan salep minyak larva BSF dosis 5%, 10%, dan 15%. Perlakuan dioleskan 0,15 g dua kali sehari pada punggung mencit selama 14 hari. Parameter penelitian yang dianalisis meliputi karakteristik salep minyak larva BSF, kandungan senyawa minyak larva BSF, perbaikan morfologi luka dan histologi kulit, kuantitas komponen leukosit, serta gejala toksisitas. Hasil penelitian menunjukkan bahwa salep minyak larva BSF memiliki karakteristik yang baik berdasarkan standar pengujian salep serta mengandung 14 senyawa asam lemak yang memiliki bioaktivitas antara lain sebagai antiinflamasi, antinosiseptif, antimikroba, antivirus, antifibrotik, antioksidan, serta imunomodulator. Salep minyak larva BSF 5% merupakan dosis terbaik ditinjau dari perbaikan morfologi luka dan histologi kulit serta mampu menormalkan kadar komponen leukosit dalam darah. Penggunaan salep minyak larva BSF tidak bersifat toksik berdasarkan indikator toksisitas. Berdasarkan hasil penelitian, pengaplikasian salep minyak larva BSF sangat berpotensi dalam penyembuhan luka yang berbasis bahan alam
Pengaruh Pemberian Minyak Maggot Black Soldier Fly (BSF) Hermetia illucens L. (Diptera : Stratiomyidae) Terhadap Penyembuhan Luka Sayat Pada Mencit Putih (Mus musculus L.)
Full text linkLuka sayat merupakan luka yang berbentuk garis yang beraturan yang ditandai dengan adanya tepi luka. Maggot BSF memiliki kandungan protein dan asam lemak yang tinggi sehingga diduga memiliki potensi dalam proses penyembuhan luka. Terdapat 4 fase dalam proses penyembuhan luka yaitu fase hemostasis, fase inflamasi, fase proliferasi, dan fase remodelling luka. Penelitian ini bertujuan untuk mengamati morfologi dan persentase penyembuhan luka berdasarkan perubahan panjang luka, jumlah komponen leukosit, serta kandungan utama senyawa minyak maggot BSF. Penelitian ini menggunakan metode eksperimental dengan 4 perlakuan, yaitu perlakuan kontrol (P0), perlakuan dengan povidon iodine 10% (P1), perlakuan dengan minyak maggot BSF satu kali sehari (P2), dan perlakuan dengan minyak maggot dua kali sehari (P3) selama 9 hari. Hasil penelitian ditemukan panjang luka terkecil pada perlakuan kontrol (P0) berdasarkan pengamatan morfologi dan persentase penyembuhan luka terbesar pada perlakuan dengan minyak maggot satu kali sehari (P2) sebesar 62%. Nilai komponen leukosit signifikan (p<0,05) pada jumlah limfosit hari ke-3 pada perlakuan dengan minyak maggot satu kali sehari (P2) berdasarkan uji statistik. Senyawa utama dengan kadar tertinggi Dihydroxyflavanone dari golongan flavonoid berdasarkan uji GCMS. Kesimpulannya, pemberian minyak maggot BSF memiliki kemampuan yang setara dengan pemberian obat komersil (povidon iodine 10%) terhadap penyembuhan luka sayat pada mencit
Variations on the Author
Full text link“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
Full text linkWe 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
Full text linkWe 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
