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
PENINGKATAN KUALITAS PUPUK ORGANIK CAIR DARI LIMBAH CAIR PRODUKSI BIOGAS MENGGUNAKAN COMPOSTAR
Get PDFQuality Improvement  of  Liquid  Organic  Fertilizer from Water Waste  of Biogas Using Compostar         It had been improved the quality of the liquid organic fertilizer from waste of Biogas production with the addition of inoculant ( F1 and F2 ) and without inoculant (F0) also additives ( V1 , V2 and V3 ) . Variations of a given treatment comprised of F0V0 (as control), F0V1 , F0V2 , F0V3 , F1V1 , F1V2 , F1V3, F2V1 , F2V2 and F2V3 using experimental design of CRD (Completely Randomized Design) with 3 x replications . Liquid fertilizer quality parameters measured were : temperature , pH , organic-C , total-N and P. While the parameters measured in the corn biomass is wet weight , dry weight , levels of N and P. The results showed that the addition of biofertilizer Compostar isolates (F2) were able to decompose the form of additives to the maximum compared with (F1) and without (F0) the addition of commercial inoculant  with an average content of N - total of  823.2 mg / L and the average P2O5  content of 187.7 mg / L. While the addition of additives could increase levels of  N - total and P2O5 , where the levels of  N - largest total in the treatment of V3 ( Tp.fish Tp.bone 2 % and 2% ) with an average of 967.6 mg / L , while the largest concentration of P2O5 in treatment V1 ( Tp.fish 2 % ) with an average of 154.4 mg / L. Liquid organic fertilizer did not significantly affect the levels of nutrient uptake , biomass dry weight of corn plants , but had significant effect on plant height , stem large and heavy wet corn crop biomass , was the treatment of F2V2 with the addition of biofertilizer that isolates composter and additives in the form of bone meal 2 % .Keywords :  liquid organic fertilizer, biogas sludge, compostar ABSTRAK       Telah dilakukan peningkatan kualitas pupuk organik cair dari limbah produksi biogas dengan penambahan inokulan  ( F1 dan F2) dan tanpa penambahan inokulan (F0) serta penambahan zat aditif (V1, V2 dan V3).  Variasi perlakuan yang diberikan  terdiri dari F0V0  sebagai kontrol, F0V1 , F0V2 , F0V3 , F1V1 , F1V2 , F1V3 , F2V1 , F2V2 , dan F2V3   menggunakan rancangan percobaan RAL ( Rancang Acak Lengkap) dengan 3 x ulangan. Parameter kualitas pupuk cair yang diukur , yaitu : suhu, pH, C-organik, N-total dan P. Sedangkan parameter pada biomassa jagung yang diukur adalah bobot basah, bobot kering, Kadar hara N dan P. Hasil yang diperoleh menunjukkan bahwa penambahan biofertilizer berupa isolate Compostar (F2) mampu menguraikan zat aditif secara maksimal dibandingkan dengan inokulan komersil (F1) dan tanpa penambahan inokulan (F0) dengan rataan kandungan N-Total sebesar 823,2 mg/L dan rataan kandungan P2O5 sebesar 187,7 mg/L. Sedangkan penambahan zat aditif mampu meningkatkan kadar N-Total dan P2O5, dimana kadar N-Total terbesar pada perlakuan V3( Tp.ikan 2% dan Tp.Tulang 2%) dengan rataan sebesar 967,6 mg/L, sedangkan kadar P2O5 terbesar pada perlakuan V1 (Tp.ikan 2%) dengan rataan sebesar 154,4 mg/L. Pemberian pupuk organic cair tidak berpengaruh nyata terhadap serapan kadar hara, berat kering biomassa tanaman jagung, tetapi berpengaruh nyata terhadap tinggi tanaman,besar batang dan berat basah biomassa tanaman jagung, yakni pada perlakuan F2V2 yaitu dengan penambahan biofertilizer isolate composter dan zat aditif berupa tepung tulang 2%.Kata Kunci : pupuk organik cair, sludge biogas, compostar
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
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
