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
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
Pengaruh Indole Butyric Acid (IBA) dan Naphthalene Acetic Acid (NAA) terhadap pertumbuhan stek pucuk Corymbia sp.
Full text linkPenggunaan zat pengatur tumbuh Indole Butyric Acid dianggap belum menghasilkan pengadaan stek yang maksimal. Penelitian ini diperlukan agar mendapatkan hasil jenis zat pengatur tumbuh yang tepat dan terarah sehingga dapat meningkatkan mutu stek Corymbia sp. yang sesuai dengan standar dan kuantitas. Penelitian ini bertujuan mengetahui pengaruh berbagai zat pengatur tumbuh campuran IBA dan Naphthalene Acetic Acid terhadap pertumbuhan akar stek Corymbia sp. Clone IND 125. Penelitian eksperimen yang digunakan menggunakan percobaan faktor tunggal dengan Rancangan Acak Lengkap. Parameter yang diamati antara lain: tinggi stek, persentase stek hidup, persentase stek berakar, panjang akar, jumlah akar, dan jumlah daun. Hasil penelitian menunjukkan bahwa penggunaan campuran ZPT terbukti berpengaruh nyata terhadap parameter daya bertahan hidup serta kemampuan berakar. Perlakuan pemberian kombinasi ZPT IBA 3000 ppm + NAA 2000 ppm merupakan perlakuan yang optimal dengan persentase kemampuan berakar sebesar 38,51%
KARAKTERISTIK FENOTIP KEMENYAN (Styrax spp.) DI DESA TARLOLA KECAMATAN BATANG NATAL, KABUPATEN MANDAILING NATAL, PROVINSI SUMATERA UTARA
Full text linkFrankincense is a resin or sap that has been processed from trees of the Styracaceae family which is used for a mixture of incense ingredients medicines and the process of preserving corpses or commonly called mummies. In North Sumatra Province the production of the sap reached 4.969,04 ton, but in Tarlola Village, the management was not yet optimal so this research was conducted to find initial information regarding its phenotypic characteristic. The study obtained quantitative phenotypic data including leaf and stem sizes and analyzed descriptively. The results showed that there were no significant differences in quantitative data such as stem diameter, mature leaf area and old leaf area at different growing sites. The phenotipic characters obtained were pointed leaf tips, rounded leaf bases, flat leaf edges, light green and dark green leaf colors. The average tree trunk diameter is 43,94 cm with an estimated tree age of 6 years. INTISARIKemenyan adalah resin atau getah hasil pengolahan dari pohon familia Styracaceae yang biasa nya digunakan untuk campuran pembuatan dupa atau wewangian, obat-obatan dan proses pengawetan mayat. Di Provinsi Sumatera Utara produksi getah ini mencapai 4.969,04 ton/tahun, namun di Desa Tarlola, pengelolaannya belum optimal sehingga penelitian ini dilakukan untuk mencari informasi awal terkait karakteristik fenotipnya. Penelitian mendapatkan data fenotip kuantitatif antara lain ukuran daun dan batang dan dianalisis secara deskriptif. Hasil analisis memperlihatkan informasi kualitatif yaitu bentuk daun, diamter batang, bentuk batang dan lain-lain. Dimana hasil penelitian menunjukkan perbedaan yang nyata pada tempat tumbuh yang berbeda. Karakter fenotip yang didapatkan yaitu ujung daun runcing, pangkal daun membulat, tepi daun rata, warna daun hijau muda dan hijau tua. Untuk ukuran diameter batang pohon rerata yaitu 43,94 cm dengan taksiran umur pohon yaitu 6 tahun
