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
Pra Desain Pabrik Magnesium Hidroksida (Mg(OH)2) dari Bittern
No full textBittern merupakan salah satu hasil samping dari proses produksi garam yang berupa cairan pekat dengan kadar >29º Be (Baume). Bittern memiliki beberapa kandungan ion mineral diantaranya yang paling besar adalah Na+, Mg2+ dan Cl-. Lokasi yang dipilih dalam pendirian pabrik ini direncanakan di Kabupaten Sampang, Jawa Timur pada tahun 2027 dengan kapasitas produksi sebesar 1.850 ton/tahun. Proses yang digunakan dalam pembuatan Mg(OH)2 dari bittern yaitu presipitasi magnesium menggunakan NaOH dengan pertimbangan yield yang dihasilkan lebih tinggi dibandingkan dengan penggunaan senyawa basa yang lain. Secara umum, proses ini dibagi menjadi 3 unit proses, yaitu proses pre-treatment bahan baku, proses presipitasi magnesium, proses drying dan milling. Tahap pre-treatment bittern dilakukan secara dua tahap, yaitu filtrasi charcoal dan pengurangan ion Ca2+. Filtrasi charcoal bertujuan untuk menghilangkan zat chroma dan zat pengotor yang terikut dalam bittern, serta pengikatan kadar kalsium dalam bittern menggunakan H2SO4. Tahap presipitasi magnesium bertujuan untuk mengikat ion-ion Mg2+ dalam bittern dan bereaksi dengan ion (OH-) dari NaOH sehingga menghasilkan Mg(OH)2.. Dimana Mg(OH)2 memiliki nilai kelarutan senyawa yang paling rendah diantara senyawa lain yang terbentuk, sehingga terjadi adanya pengendapan dan dapat dengan mudah dilakukan pemisahan dan pencucian pada proses selanjutnya. Tahap drying dan milling, terjadi proses pengeringan cake Mg(OH)2 untuk menghilangkan kadar air yang tersisa dengan bantuan panas secara berlawanan serta terjadi proses size reduction untuk menghasilkan ukuran yang seragam yaitu 100 mesh. Untuk mendirikan pabrik magnesium hidroksida dengan kapasitas 1.850 ton/tahun dibutuhkan modal investasi sebesar Rp. 214.287.272.351 yang diperoleh dari modal sendiri sebesar 30% dan pinjaman jangkan pendek dengan bunga 8% per tahun sebesar 70%. Dari analisa ekonomi, didapatkan penaksiran modal (CAPEX) sebesar Rp. 186.813.411.607 dan biaya operasional (OPEX) sebesar Rp. 54.947.721.488. Hasil penjualan produk per tahun sebesar Rp. 92.500.000.000 dengan IRR 15,94%, waktu pengembalian modal 6,05 tahun dan NPV sebesar Rp. 135.472.885.944,20 (positif) dan WACC sebesar 7,24%. Berdasarkan kelayakan di atas dapat disimpulkan bahwa pabrik ini layak untuk didirikan karena nilai WACC < IRR.

Bittern is one of the by-products of the salt production process in the form of aconcentrated liquid with >29º Be (Baume). Bittern contains several mineral ions, the largest being Na+, Mg2+ and Cl-. Selected location for the construction of this factory is planned in Sampang Regency, East Java in 2027 with a production capacity of 1,850 tons/year.The process used in the manufacture of Mg(OH)2 from bittern is magnesium precipitation using NaOH with the consideration that the resulting yield is higher compared to the use of other basic compounds. In general, this process is divided into 3 process units, pre-treatment process, magnesium precipitation process, drying and milling process. The pre-treatment process of bittern was carried out in two stages, are charcoal filtration and reducing Ca2+ ions. Charcoal filtration aims to remove chroma and impurities contained in bittern, while reduce calcium levels in bittern using H2SO4. The magnesium precipitation aims to bind Mg2+ ions in bittern and react with (OH-) ions from NaOH to produce Mg(OH)2. Where Mg(OH)2 has the lowest solubility value among the other compounds formed, so that precipitation occurs and can be easily separated and washed in the next process. In the drying and milling process, the Mg(OH)2 cake drying process occurs to remove the remaining moisture content with the help of heat in the opposite direction and a size reduction process occurs to produce a uniform 100 mesh size. To set up a magnesium hydroxide plant with a capacity of 1,850 tons/year, the investment capital is Rp. 214.287.272.351 obtained from 30% own capital and short-term loans with interest of 8% per year 70%. From the economic analysis, the estimated capital (CAPEX) is Rp. 186.813.411.607 and operational costs (OPEX) of Rp. 54.947.721.488. Product sales results per year amounting to Rp. 92,500,000,000 with an IRR of 16,29%, a payback period of 6,05 years and an NPV of Rp. 135.472.885.944,20 (positive) and WACC 7.24%. Based on the feasibility above, it can be concluded that this factory is feasible to build because the WACC value <IRR
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.
