Going Beyond Counting First Authors in Author Co-citation Analysis
The 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
“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
We 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
We 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
EFFECT OF USEOF KATUK LEAF EXTRACT, LEMURU FISH OIL AND VITAMIN E TO PERFORMANCE AND QUALITY OF BROILER CHICKENS
This research was conducted to determine the effect of leaf extract katuk (EDK), lemurufish oil (MIL) and vitamin E as a substitute for a commercial feed supplement on performance and quality of broiler chickens. The total of 195 birds were used as objects in this study. Design research used Completely Randomized Design (CRD) with 13 treatments and 3 replications. Each test consisted of five broiler chickens. The data obtained were analyzed according to the design used and Test DMRT (Duncan Multiple Range Test) to examine differences in treatment effect. The results showed that the use katuk leaf extract, lemuru oil, and vitamin E did not differ significantly (P>0.05) on ration consumption, weight gain, feed conversion and internal organ weight of broiler chickens. In contrast, there were highly significant differences (P<0.01) on serum, cholesterol level, triglyceride, LDL cholesterol and HDL cholesterol. Similarly, feeding sauropus androgynus extract and lemuru fish oil plus vitamin E are highly significantly (P <0.01) affected weat cholesterol, fant and protein
Pengaruh Penggunaan Ekstrak Daun Katuk , Minyak Ikan Lemuru dan Vitamin E terhadap Komposisi Asam Lemak dan Asam Amino Daging Broiler
ABSTRAK
Penelitian ini dilakukan untuk mengetahui pengaruh penggunaan ekstrak daun katuk, minyak ikan lemuru dan vitamin E sebagai feed suplement terhadap komposisi asam lemak dan asam amino daging broiler. Seratus sembilan puluh lima ekor ayam broiler didistribusikan menjadi 13 kelompok perlakuan yaitu : P0 : Pakan mengandung feed suplement komersial (pakan kontol). P1: 9 g/kg ekstrak daun katuk (EDK) + 1% minyak ikan lemuru. P2: 9 g/kg ekstrak daun katuk (EDK) + 1% minyak ikan lemuru + 60 mg vit E. P3: 9 g/kg ekstrak daun katuk (EDK) + 2% minyak ikan lemuru. P4: 9 g/kg ekstrak daun katuk (EDK) + 2% minyak ikan lemuru + 60 mg vit E. P5: 9 g/kg ekstrak daun katuk (EDK) + 3% minyak ikan lemuru. P6: 9 g/kg ekstrak daun katuk (EDK) + 3% minyak ikan lemuru + 60 mg vit E. P7: 18 g/kg ekstrak daun katuk (EDK) + 1% minyak ikan lemuru. P8: 18 g/kg ekstrak daun katuk (EDK) + 1% minyak ikan lemuru + 60 mg vit E. P9: 18 g/kg ekstrak daun katuk (EDK) + 2% minyak ikan lemuru. P10: 18 g/kg ekstrak daun katuk (EDK) + 2% minyak ikan lemuru + 60 mg vit E. P11: 18 g/kg ekstrak daun katuk (EDK) + 3% minyak ikan lemuru. P12: 18 g/kg ekstrak daun katuk (EDK) + 3% minyak ikan lemuru + 60 mg vit E. Rancangan penelitian yang digunakan Rancangan Acak Lengkap (RAL) dengan 13 perlakuan dan 3 ulangan. Setiap ulangan terdiri dari 5 ekor ayam broiler, jumlah ayam dalam penelitian sebanyak 195 ekor. Data yang diperoleh dianalisis sesuai rancangan yang digunakan (Rancangan Acak Lengkap) dan Uji DMRT (Duncan Multiple Range Test) untuk menguji perbedaan pengaruh perlakuan. Hasil penelitian menunjukan bahwa penggunaan ekstrak daun katuk, minyak ikan lemuru dan vitamin E sangat nyata (P < 0.01) meningkatkan EPA, DHA, asam palmitat, dan asam stearat tetapi menurunkan asam meristat, linolenat. Terhadap komposisi asam amino daging broiler meningkatkan asam glutamat, serin, glisin, valin dan leusin.

koamabayili/VECTRON-author-checklist: VECTRON author checklist
We 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
