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
THE EFFECT OF BIO URINE APPLICATION FREQUENCIES ON THE GROWTH AND YIELDS OF ONION PLANTS (Allium fistulosum L.) ON ALUVIAL LAND

This research was carried out in the experimental garden of the Faculty of Agriculture, Tanjungpura University Pontianak, from April 6th, 2018 to May, 25th 2018. The research method used was a Completely Randomized Design (CRD) consisting of 5 treatments, namely (f1): without bio urine, (f2): appalied once in a time (14 HST), 100 ml / L water, (f3): twice application (14.24 HST), 50 ml / L water, (f4): three times application (14,24,34 HST), 33 , 33 ml / L of water, and (f5): four times of application (14,24,34,44 HST), 25 ml / L of water. Each treatment were repeated 5 times, and each experimental unit consisted of 3 plant samples, so that the total number of plants were 75 plants. Observation variables in this study were plant height (cm), root volume (cm3), number of tillers per clump (fruit), plant fresh weight per clump (g), and plant dry weight per clump (g). The results of this study indicated that the effect of the frequency of 100 ml bio-urine giving the same response to the plant height, root volume, number of tillers, fresh weight and dry weight of onion leaves.

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
CHARACTERIZATION OF TABAH BLACK RICE TYPE CULTIVATED IN TIDAL RICE FIELD
No full textABSTRACT Characterization was very essential to identify the description of the black rice type characters. This study aims to determine the morphological and agronomic characteristics of Tabah black rice qualitatively and quantitatively, based on the Guidance of Rice Characterization and Evaluation System (Ministry of Agriculture, 2003). The research was carried out in tidal rice at the Sungai Kakap Seed Center Developer. Observations were made measure the qualitative and quantitative black rice phenotypes. The results showed that the agronomic character of Tabah black rice had the ability to medium breed (14 tillers), plant height in the maximum vegetative phase 119,08 cm classified as medium, panicle and overall neck panicle emergence, grain fertility 84,48% classified as fertile and plant age 151 days, and were classified as deep length. Morphological characters were seed height 37,48 cm, leaf length 58,72 cm classified as medium, leaf width 1,72 cm classified as wide, surface of rough hairy leaves, 37,6o leaf angle classified as upright, flag leaf angle 44,8o classified as medium, light green leaf neck, white leaf ears colorless, golden yellow leaf segment, light green leaves (Yellow-Green Group 146 B), green leaf midrib, ligula is 1,8 cm classified as long, ligula is white (Yellow-Green Group 145 A), ligula shape is 2-cleft, the stem angle was 33,7o classified as medium, the stem was yellow gold (Yellow-Green Group 151 D), the panicle was 27,43 cm, panicle type was between medium and open, drooped panicle, seed length 9,87 mm was classified as very long, seed width was 2,72 mm, seed thickness was 2,05 mm and weight of 100 grains was 2,17 grams with 13,6% moisture content.

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
