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
Characterization of 56 Soybean Accessions on Yield Components and Maturity-related Traits
No full text<p>Peningkatan produktivitas kedelai nasional dapat dilakukan dengan penggunaan varietas produktivitas tinggi dan manipulasi indeks panen menggunakan varietas genjah. Pembentukan varietas di atas memerlukan plasma nutfah dengan potensi hasil tinggi dan berumur genjah. Tujuan dari penelitian ini adalah untuk mengidentifikasi aksesi kedelai yang mempunyai potensi hasil tinggi dan aksesi kedelai berumur genjah. Sebanyak 56 aksesi kedelai terdiri atas varietas elit dan introduksi, aksesi lokal dan galur-galur persilangan ditanam di Kebun Percobaan Cikeumeuh (250 m dpl) dan Pacet (1.200 m dpl) menggunakan Rancangan Acak Kelompok dengan tiga ulangan. Pengamatan dilakukan terhadap karakter morfologi, komponen hasil dan karakter reproduktif yang meliputi umur berbunga (fase R1, R3, R7, dan R8). Hasil penelitian menunjukkan 28 aksesi (50%) diuji di Cikeumeuh dan 43 aksesi (76,79%) diuji di Pacet menunjukkan jumlah polong/tanaman lebih dari 50. Sekitar 35,71% aksesi di Cikeumeuh dan 41,07% aksesi di Pacet menghasilkan biji/tanaman lebih dari 10 g/tanaman. Aksesi kedelai yang menunjukkan komponen hasil tinggi hanya di KP Cikeumeuh adalah B2981, B3517, dan B3628. Aksesi kedelai yang menunjukkan komponen hasil tinggi hanya di KP Pacet adalah B4441, B3628, B382, B4334, dan B3414. Aksesi yang menunjukkan komponen hasil tinggi di kedua lokasi (Cikeumeuh dan Pacet) adalah B3417. Aksesi B3417 diklasifikasikan sebagai aksesi dengan adaptasi luas karena berkeragaan komponen hasil tinggi di dataran rendah dan di dataran tinggi. Aksesi dengan umur panen genjah ditunjukkan oleh B2973 (74 hari setelah tanam, hst) yang tidak berbeda nyata dengan aksesi B1430 (75 hst), B3611 (76 hst), B4433 (77 hst), dan B4439 (80 hst) berdasarkan uji DMRT (p&lt;0,05). Berdasarkan karakter morfologi, sebagian besar plasma nutfah kedelai terbagi dalam tiga kelompok termasuk landraces tanpa mempertimbangkan asal daerahnya. Analisis klaster berdasarkan karakter agronomi mendukung analisis DMRT bahwa aksesi kedelai dengan hasil biji tinggi dan umur genjah dapat dibedakan. Aksesi kedelai dengan jumlah polong banyak, hasil biji tinggi, umur genjah potensial digunakan dalam program pemuliaan kedelai produktivitas tinggi dengan umur genjah.</p><p> </p><p><strong>Abstrak</strong></p><p>One effort to improve soybean production in Indonesia is by using high yielding and manipulating harvest index by using early maturing varieties. Such variety development requires the availability of soybean germplasm with high yield potential and early maturity. The objective of this study was to identify soybean genotypes showing high yield potential and early maturity. A total of 56 soybean accessions consisting of elite and introducing varieties, landraces, and breeding lines were characterized in the field with different altitudes i.e. Cikeumeuh (250 m above sea level) and Pacet (1.200 m asl). The experiments were arranged in a randomized block design using three replications. Characters observed were morphological chracters, yield components and maturity-related traits (days to R1, R3, R7, and R8). Results showed that 28 accessions (50%) tested at Cikeumeuh and 43 accessions (76.79%) tested at Pacet demonstrated pod number/plant more than 50. About 35.71% at Cikeumeuh and 41.07% at Pacet showed seed yield more than 10 g/plant. Soybean accessions demonstrating high yield components only at Cikeumeuh were B2981, B3517, and B3628. Soybean accessions demonstrating high yield components only at Pacet were B4441, B3628, B382, B4334, and B3414. The accession demonstrating high yield component performance at both locations (Cikeumeuh and Pacet) was shown by B3417. Accession B3417 is then classified as a broad adaptating soybean genotype. The early pod maturing accession was demonstrated by B2973 (74 dap) that was not significantly different from accessions B1430 (75 dap), B3611 (76 dap), B4433 (77 dap), and B4439 (80 dap) based on DMRT at p = 0.05. Three distinct clades were generated based on morpho-agronomical variables on both locations (Cikeumeuh dan Pacet). Cluster analysis of agronomical characters was able to distinguish accessions with high yield components in either one or both locations (B3417, B3628, and B2981), and accessions with early maturiy and least pod number (B4439 and B4433). Cluster analysis results were in well-agreement with the results based on DMRT. Soybean accessions having high pod number, high seed yield and early in maturity are potentially used for developing high yielding soybean varieties with early in maturity.</p></jats:p
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

Author Under Sail The Imagination of Jack London, 1893-1902
No full textIn Author Under Sail, Jay Williams offers the first complete literary biography of Jack London as a professional writer engaged in the labor of writing. It examines the authorial imagination in London's work, the use of imagination in both his fiction and nonfiction, and the ways he defined imagination in the creative process in his business dealings with his publishers, editors, and agents. In this first volume of a two-volume biography, Williams traverses the years 1893 to 1902, from London's "Story of a Typhoon" to The People of the Abyss. The Jack London who emerges in the pages of Author Under Sail is a writer whose partnership with publishers, most notably his productive alliance with George Brett of Macmillan, was one of the most formative in American literary history. London pioneered many author models during the heyday of realism and naturalism, blurring the boundaries of these popular genres by focusing on absorption and theatricality and the representation of the seen and unseen. London created an impassioned, sincere, and extremely personal realism unlike that of other American writers of the time. Author Under Sail is a literary tour de force that reveals the full range of London as writer, creative citizen, and entrepreneur at the same time it sheds light on the maverick side of machine-age literature.Intro -- Title Page -- Copyright Page -- Dedication -- Contents -- Acknowledgments -- Introduction -- 1.
