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
RESPON PERTUMBUHAN DAN HASIL TANAMAN CABAI (Capsicum annum L.) TERHADAP PENGURANGAN DOSIS NPK 16:16:16 DENGAN PEMBERIAN PUPUK ORGANIK
Full text linkLow soil fertility in Riau impact on low production of chilli. The low production of chilli caused by improper application of fertilizer. The addition of organic matter has the potential to reduce the dose of inorganic fertilizers and improve soil fertility. This research aims to determine the response to growth and yield of chili on reduction of dose NPK 16:16:16 with organic fertilizer. This research was conducted from February to June 2016 at the Experimental Farm, Faculty of Agriculture, Islamic University of Riau. The research used a completely randomized design with 3 replications. Factors dose of NPK fertilizer consists of five levels i.e., without NPK, 100%, 75%, 50%, and 25% of the dose of NPK. Factors organic fertilizers consists of three levels i.e., chicken manure, liquid bioorganic, and chicken manure + liquid bioorganic. The results showed that chicken manure fertilizer or with the addition of liquid bioorganic fertilizer can reduce the NPK usage by up to 50% without affecting the growth and yield of chili. Reduction of dose NPK 16:16:16 up to 75% gave growth and yield not statistically different in the level of α 0:05 with 100% dose of NPK. Treatment of organic fertilizer (chicken manure or with liquid bioorganic fertilizer) significantly increased the growth and yield of chili on the level of α 0:05
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
Shade Tolerance of 20 Genotypes of Tomato (Lycopersicon esculentum Mill.).
No full textTomato is one of the major vegetable that has been cultivated in Indonesia. Decrease of harvest area of tomato affect decreasing in production, so it requires an effort to improve tomato production. The efforts to improve tomato production were use the land under trees, agroforestry, or intercropping system. Low light intensityis a limiting factor in the cultivation of intercropping. Aim of this study was to evaluate the production, morphosiology, and fruit quality of 20 tomato genotypes under shade. This studywas conducted at Cikabayan (experimental station-University Farm of IPB) from January to April 2013. The research was arranged by nested design with 3 replicates. The main plot was shade consisted of four levels, i.e., 0, 25, 50, and 75%, while sub plot was 20 genotypes of tomato i.e. Intan (T1), GIK (T3), SSH 3 (T6), Karina (T13), Roma (T21), Rempai (T23), Apel (T30), SSH 9 (T33), SSH 20 (T34), M4HH (T43), Bogor (T53), Medan 4 (T57), Kediri 1 (T60), Papua 2 (T64), Montero (T80), Fatma (T82), Ratna (T83), Delana (T84), Palupi (T85), dan Mawar (T86). Results of this study showed that most of the tested genotypes increased the production per plant under 25% shade, while under 50% shade showed a high diversity among genotypes. Based on relative yield under 50% shade, genotypes can be grouped into three, there are : sensitive (Intan, Rempai and Delana), tolerant (GIK, Roma, SSH 9, SSH 10, Bogor, Kediri 1, Montero, Ratna, and Mawar), dan shade-like (SSH 3, Karina, Apel, M4HH, Medan 4, Papua 2, Fatma, and Palupi). Production per plants affected by the yield component, mainly number of fruit per plant. 50% shade significantly affected some morphologicsl characters ie plant height, and leaf area. 50% shade increase significantly up to 68% on plant height and 45% on leaf area. More over on physiological character, 50% shade significantly affect leaf thickness, chlorophyll a and b, and the ratio of chlorophyll a/b. 50 % shade significantly reduced tomato leaf thickness up to 25 %. Chlorophyll a and b increased by level of shade, while the ratio of chlorophyll a/b decreases. Shade also affects the quality of tomato fruits. Tomato diameter increase significantly by 7 % on shade-like genotype in 50 % shade. 50% shade not significant on firmness, otherwise decrease significantly on total solid soluble but increasing total titration acid on shade-like genotype
