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
Morphological and Physiological Characteristics of Shading Tolerant and Sensitive Mungbean Genotypes
No full textStudy of morphological and physiological characteristics of the tolerant and sensitive mungbean genotypes to shading was carried out in the Station Research of the Indonesian Legume and Tuber Crops Research Institute (ILETRI) from September to December 2004. Nine tolerant genotypes (MMC 87 D-KP-2, MLG 369, MLG 310, MLG 424, MLG 336, MLG 428, MLG 237, MLG 429, and VC2768B) and three sensitive genotypes to shading (Nuri, MLG 460, and MLG 330) were tested in two shading levels, that were without shading and shading of 52%. The randomized complete block design with three replications analysis. The results showed that leaf characters of shading tolerant and sensitive genotypes were different. The shading tolerant mungbean genotypes had good response to light stress so that the growth and development of the leaves were better than that of sensitive genotypes. The shading tolerant mungbean genotypes had bigger and thicker leaves than that of sensitive genotypes. The shading treatments caused reducing rate of PAR absorption, transpiration, photosynthesis, and CO2 stomata conductance. The reduction of all parameters in tolerant genotype was smaller than that of sensitive genotype. The specific leaf area at four weeks after planting could be used as shading tolerant indicator of mungbeans
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
Penampilan Karakter Kuantitatif Genotipe Kedelai di Bawah Naungan (Quantitative Characters of Soybean Genotype Performance Under The Shade)
No full textCahaya matahari merupakan sumber energi utama dalam proses fotosintesis. Di setiap habitat, intensitas
cahaya bervariasi secara temporal dan spasial. Tanaman mengembangkan daya aklimatisasi dan plastisitasnya
untuk mengatasi permasalahan tersebut. Setiap tanaman memberikan respon berbeda terhadap naungan dan
mengekspresikannya melalui penampilan karakter yang beragam. Penelitian ini bertujuan untuk mengetahui
kemampuan genotipe kedelai dalam menghadapi naungan. Penelitian dilaksanakan di Kebun Percobaan (KP)
Kendalpayak, Malang pada tahun 2013. Penelitian menggunakan rancangan percobaan faktorial, dengan dua
faktor. Faktor pertama adalah naungan, terdiri dari tanpa naungan (N0) dan naungan 50% (N1). Faktor kedua
adalah genotipe kedelai, terdiri dari tiga varietas peka naungan (Grobogan, Argopuro, dan Panderman), dua
varietas tahan (Dena 1 dan Dena 2), dan dua galur hasil persilangan (IBM-10-75 dan K-13). Penempatan
perlakuaan didasarkan pada rancangan acak kelompok lengkap, diulang tiga kali. Pengamatan meliputi: tinggi
tanaman, jumlah daun, luas daun, diameter batang, bobot biji per tanaman, bobot 100 biji dan bobot kering:
total, akar, batang, daun, dan polong. Hasil penelitian menunjukkan bahwa perlakuan naungan 50%
menyebabkan cekaman kekurangan cahaya, dengan intensitas 30,31%. Intensitas cekaman tersebut,
menyebabkan perbedaan penampilan karakter kuantitatif diantara genotipe yang diuji. Dena 1, Dena 2, dan K13
sesuai untuk lingkungan naungan, karena mampu mempertahankan atau meningkatkan hasil biji, sedangkan
Argopuro, IBM-10-75, Grobogan, dan Panderman tidak sesuai untuk lingkungan naungan, karena tidak mampu
mempertahankan hasilnya. Dena 1 dan Dena 2 mengembangkan mekanisme penghindaran untuk menghadapi
naungan, melalui peningkatan tinggi tanaman, jumlah dan luas daun, sedangkan K-13 menghadapi cekaman
naungan melalui kemampuannya dalam memanfaatkan cahaya terserap untuk pembentukan biji secara efisien
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
Interaksi genotipe x lingkungan dan stabilitas karakter agronomi kedelai (Glycine max (L.) Merrill)

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
