No full textAnggria Lestami. 2019. “Diversity and genetic identification of soybean mutant (Glycine max (L) Merril) resistant Athelia rolfsii Curzi based on SSR markers”, supervised by Diana Sofia Hanafiah and Revandy I. 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. M. Damanik. Penelitian ini bertujuan untuk mengidentifikasi genetik dan keragaman genetik galur mutan kedelai resisten Athelia rolfsii Curzi berdasarkan marka SSR. Penelitian dilakukan di Laboratorium Bioteknologi Tanaman Fakultas Pertanian Universitas Sumatera Utara, Medan pada bulan Januari - Mei 2019. Sebanyak 13 galur mutan kedelai, varietas Anjasmoro sebagai tetua dan Kipas Putih sebagai pembanding resisten Athelia rolfsii Curzi dianalisis secara deskriptif dengan mengamati pola pita DNA menggunakan 5 primer SSR Satt009, Satt114, Satt147, Satt191, Satt197. Hasil penelitian menunjukkan bahwa primer yang digunakan spesifik dan polimorfik dengan nilai PIC berkisar 0,54-0,83 (termasuk dalam kelas informatif). Berdasarkan hasil analisis varian molekuler (AMOVA), keragaman galur mutan kedelai 44% berasal dari keragaman antar individu dalam populasi. Berdasarkan analisis filogenetik UPGMA terdapat 2 galur mutan yang teridentifikasi memiliki karakter resisten Athelia rolfsii Curzi sesuai dengan varietas pembanding pada kesamaan genetik 0,92 yaitu M100-A25(3/7) dan M200-A17(13/6).94 HalamanTesis Magiste
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
Square Dancing with the Stars to Enhance Dynamic Hirschman Linkages?
No full textIn this Presidential Address, the author takes the reader on a reconnaissance of his life and time as a regional scientist. He points out scenery he found scintillating along the way, hoping that some may pick up the banner and chew on a few of the ideas for a while. He suggests a revisit to Albert O. Hirschman’s notion of key sectors and more empirical analysis related to Marcus Berliant’s and Masahisa Fujita’s notion of knowledge creation and transfer.Presidential Address, San Antonio, Texas, March 29, 2014 (53rd Meetings of the Southern Regional Science Association
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
