Uji Kekerabatan Aksesi Cengkeh di Kebun Percobaan Sukapura
No full text<p>Clove (Syzygium aromaticum L. Merril &amp;amp; Perry) is One of the Oldest Spices in the World. Clove is an evergreen tree with unopened flower bud. It is indigenous to Moluccas Island of Indonesia. Clove are mainly used as an ingredient of a variety of food specialties, beverages, medicines, and cigarettes industry. It is important to have germplasm collection in plant breeding program. Twenty eight accessions have been planted at Sukapura Experimental Garden, Probolinggo, East Java. The objective of this study was to estimate the genetic relationship among 28 clove accessions. The observations were made on fifteen morphological characters and six yield component characters. Eleven morphological characters and one yield component character had wide genetic variability. By applying cluster analysis, a dendogram was constructed to differentiate morphological differences among the accessions. The dendogram showed that the grouping of the accessions at different hierarchical levels, based upon the variation was observed. Results showed that the accession of clove could be classified into four groups. The first group only consisted of Zanzibar 5, the second group consisted of Zanzibar 13 and Siputih 5, the third group only consisted of Zanzibar 8, and 24 accessions belong to the fourth groups.</p><p> </p><p><strong>Abstrak</strong></p><p>Cengkeh (Syzygium aromaticum L.

Bunga kering cengkeh sering digunakan sebagai bahan untuk bumbu, obat-obatan, kosmetik, dan industri rokok. Koleksi plasma nutfah merupakan hal yang penting dalam suatu program pemuliaan tanaman. Dua puluh delapan aksesi cengkeh ditanam di Kebun Percobaan Sukapura, Probolinggo, Jawa Timur. Penelitian ini bertujuan mengetahui hubungan kekerabatan di antara 28 aksesi cengkeh. Pengamatan dilakukan terhadap 15 karakter morfologi dan 6 karakter komponen hasil. Sebelas karakter morfologi dan satu karakter komponen hasil memiliki keragaman genetik yang luas. Dengan menggunakan analisis kluster ditentukan pengelompokan berdasarkan perbedaan sifat morfologi di antara 28 aksesi tanaman cengkeh. Gerombol I, yaitu Zanzibar 5, Gerombol II terdiri atas Zanzibar 13 dan Siputih 5, Gerombol III, yaitu Zanzibar 8, dan Gerombol IV terdiri atas 24 aksesi lainnya.</p></jats:p
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
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
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
Evaluasi Tingkat Serangan Penggerek Buah Kopi Hypothenemus hampei (Coleoptera: Curculionidae) pada Kultivar Kopi Arabika AGK-1
No full text<em>The yellow Arabica coffee (AGK-1) is a superior local cultivar that has been widely developed in the Garut regency and several other districts in West Java. The advantages of this cultivar are high productivity, large berry size, and specialty flavor quality. One of the obstacles in its development is the coffee berry borer (CBB attack), caused by </em>Hypothenemus hampei<em>, which is the main pest of coffee plants worldwide. The objective of the study was to evaluate the percentage of infestation in Arabica coffee cultivars of AGK-1 both in laboratory and on field studies. The research was conducted from March to August 2016. The observation of CBB infestation level in the field was carried out in Ciawer and Legok Gede Village, </em>Cikajang<em> District, Garut Regency, West Java, taken on 4 years old plants (1,450 m asl), 6 years (1,300 m asl), 9 years (1,350 m asl), and 11 years (1,300 m asl). Infestation testing of CBB was conducted in laboratory of Plant Protection of Indonesian Industrial and Beverage Crops Research Institute (IIBCRI), Sukabumi, using the method of choice and non choice test. The result showed that the percentage of </em>H. hampei<em> infestation on AGK-1 yellow Arabica coffee cultivar on field at all age and altitudes was low (3.24%–6.76%). Whereas laboratory testing showed that infestation level of CBB on yellow Arabica coffee cultivar AGK-1 as the highest, both from the choice and non choice test (51.25% and 17.5% respectively). On the other hand, the berry damage was low and not significantly different from other cultivars/varieties (19.37% and 6.25% respectively).</em></jats:p
