M. Damanik. The objective of this research was to identify the genetic and genetic diversity soybean mutant lines resistant of Athelia rolfsii Curzi based on SSR markers. The study was conducted at the Laboratory of Plant Biotechnology, Faculty of Agriculture, Universitas Sumatera Utara, Medan in January-May 2019. There were 13 soybean mutant lines, Anjasmoro varieties as elders and Kipas Putih as comparative resistant Athelia rolfsii Curzi were analyzed descriptively analyzed by observing the pattern of DNA bands using 5 primers SSR Satt009, Satt114, Satt147, Satt191, Satt197. The results showed that the primers used were specific and polymorphic with PIC values ranging from 0.54 to 0.83 (included in the informative class). Based on the analysis of molecular variants (AMOVA), the diversity of soybean mutant lines 44% comes from the diversity between individuals in the population. Based on UPGMA phylogenetic analysis, there were 2 mutant lines which were identified as having Athelia rolfsii Curzi resistant character according to comparative varieties on the genetic similarity of 0.92, namely M100-A25 (3/7) and M200-A17 (13/6).Anggria Lestami. 2019. “Keragaman dan identifikasi genetik galur mutan kedelai (Glycine max (L) Merril) resisten Athelia rolfsii Curzi berdasarkan marka SSR”, dibimbing oleh Diana Sofia Hanafiah dan Revandy I.

asam gelugur (Garcinia atroviridis Griff. ex T. Anders) in some North Sumatera
district. Supervised by Eva Sartini Bayu and Emmy Harso Kardhinata. This
reserach aimed to identify the morphological chracteristics and phylogenetic
relationship of asam gelugur in three North Sumatera district. The research was
done at Deli Serdang district, Langkat district and Serdang Berdagai district in
Mei to September 2016 with survey method using asam gelugur descriptor of
IPGRI. Sampling technique using accidental sampling. Parameters observed were
tree height, trunk height, trunk circumference, trunk surface, crown shape, young
leaf colour, mature leaf colour, leaf blade size (lenght and widht), leaf blade
shape, laef base shape, laef apex shape, laef blade margin, laef venation
appearance, flower size, position of flowers, sepal colour, petal colour, fruit
shape, number of fruit segments, fruit diameters, fruit weight, fruit size, fruit skin
thickness, mature fruit colour, seed lenght, seed widht, number of seeds per fruit,
seed shape, seed coat colour. This result of research showed that in tree North
Sumatera district there were 21 accession of asam gelugur been identified. Based
on dendogram resulted two groups, three groups and four groups phylogenetic
relationship of euclidean distance scale 20, 22 and 24 with closest relationship is

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
