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
Pengaruh Perlakuan Panas Metode Vapor Heat Treatment Terhadap Mutu Pepaya (Carica Papaya L.)
Get PDFBuah pepaya termasuk dalam kelompok hortikultura yang pengembangannya mendapat perhatian. Banyak buah-buahan yang dihasilkan para petani lokal namun masih sedikit buah yang menempati pasar swalayan dan pasar internasional. Masalah mutu yang dihadapi diantaranya penampilan buah yang kotor, memar-memar, tidak higiene, warna yang tidak merata dan citarasa buah yang tidak sama antar buah yang diperdagangkan. Buah termasuk komoditas pangan yang cepat rusak (perishable) sehingga fleksibilitas di pasaran menjadi terbatas. Bila penanganan pascapanen kurang sempurna maka sekitar 30-50% hasil panen akan mengalami kerusakan sesampai ditangan konsumen. Kerusakan ini disebabkan karena setelah dilakukan pemanenan, respirasi lanjutan atau proses hidup masih terjadi. Proses tersebut meliputi perubahan warna, respirasi, dan proses lain yang menyebabkan pembusukan oleh aktivitas mikroba. Proses tersebut dapat dikendalikan dengan adanya kegiatan pascapanen yang benar sehingga berpengaruh pada kualitas buah. Pepaya tergolong buah yang banyak diminati hampir di seluruh dunia. Daging buah yang lunak, warnanya merah atau kuning, rasanya yang manis dan mengandung banyak air. Kandungan vitamin A-nya lebih banyak daripada wortel, vitamin C-nya lebih tinggi daripada jeruk. Mengandung juga vitamin B kompleks dan vitamin E. Nilai ekspor pepaya Indonesia masih kecil. Hal ini disebabkan karena kurangnya buah pepaya bermutu tinggi yang memenuhi selera dan standar luar negeri. Rendahnya mutu pepaya disebabkan karena adanya serangan hama dan penyakit. Salah satu upaya yang dapat dilakukan untuk mengatasi hal tersebut adalah dengan teknologi karantina menggunakan teknik perlakuan panas (heat treatment). Penelitian ini bertujuan mempelajari pengaruh perlakuan panas dengan metode vapor heat treatment terhadap mutu buah pepaya dan mengamati perubahan mutu yang terjadi selama penyimpanan, meliputi susut bobot, kekerasan, total padatan terlarut, kadar air, uji organoleptik dan menentukan perlakuan terbaik terhadap mutu pepaya selama penyimpanan. Waktu penelitian mulai bulan Maret 2007 sampai dengan Juni 2007 di laboratorium AP4 (Agricultural Producs Processing Pilot Plant), dan laboratorium TPPHP (Teknik Pengolahan Pangan dan Hasil Pertanian), Fakultas Teknologi Pertanian, Institut Pertanian Bogor. Bahan baku yang digunakan adalah buah pepaya (Carica papaya L.) varietas IPB 3 dengan berat 450-600 gram, panjang 15.0 - 19.0 cm, dan diameter 7.0 – 8.5 cm. Buah pepaya diperoleh dari Pusat Penelitian Buah Tropika di Tajur, Bogor. Peralatan yang digunakan pada penelitian ini antara lain vapor heat treatment, hybrid recorder, lemari pendingin (refrigerator), termokopel, rheometer tipe CR-300 DX, refraktometer, jangka sorong, oven, dan timbangan digital. Penelitian ini terdiri dari 2 tahap kegiatan, yaitu tahap I (mengkaji perkembangan suhu buah selama proses VHT) dan tahap II (mengkaji pengaruh lama proses VHT dengan pelilinan dan tanpa pelilinan terhadap mutu buah). Perlakuan panas dilakukan dengan menempatkan pepaya pada VHT chamber dengan suhu dan kelembaban terkontrol. Perubahan suhu dan waktu yang terjadi selama perlakuan dimonitor setiap menit menggunakan hybrid recorder. Data dianalisis menggunakan SAS dan Microsoft Excel. Pada tahap II, perlakuan panas dilakukan selama 0, 15, dan 30 menit setelah conditoning pada tahap I. Kemudian pepaya diberi perlakuan pelilinan dan tanpa pelilinan. Sebagai pembanding, diperlukan pepaya kontrol (tanpa VHT) dengan pelilinan dan tanpa pelilinan. Pepaya kontrol dan pepaya yang sudah diberi perlakuan panas disimpan dalam lemari pendingin dengan suhu 10ºC dan RH 85-90%. Pengamatan mutu terhadap susut bobot, kekerasan, total padatan terlarut, dan kadar air dilakukan setiap 3 hari selama 21 hari. Setiap pengamatan dilakukan uji organoleptik terhadap warna kulit, warna daging buah, aroma, dan rasa kepada 10 orang panelis. Model matematika penyebaran suhu yang digunakan selama VHT pada mutu A, B, dan C adalah model asimtotik, dengan persamaan Tθ = 48.59 - (22.48 EXP (-0.02θ)) dengan r2 = 0.992 untuk pepaya mutu A, Tθ = 47.24 - (22.41 EXP (-0.06θ)) dengan r2 = 0.998 untuk pepaya mutu B, dan Tθ = 49.7 - (21.21 EXP (- 0.07θ)) dengan r2 = 0.993 untuk pepaya mutu C. Pepaya yang digunakan pada tahap II adalah pepaya mutu A. Suhu pusat pepaya mencapai 45.5ºC dengan suhu medium 46.5ºC dalam waktu sekitar 80 menit (conditoning). Pelilinan memberikan pengaruh nyata terhadap susut bobot, dan kadar air. Pelilinan mampu menghambat proses transpirasi dan respirasi buah sehingga susut sobot cenderung lebih kecil. VHT berpengaruh nyata terhadap perubahan total padatan terlarut dan kekerasan pepaya. Semakin lama perlakuan panas (VHT) akan menurunkan nilai total padatan terlarut dan akan memberikan efek lunak pada buah. Interaksi antara VHT dan pelilinan memberikan pengaruh nyata terhadap kekerasan pepaya selama penyimpanan. Pemberian lilin mampu menghambat efek lunak akibat pengaruh VHT selama penyimpanan. Perlakuan VHT selama 30 menit setelah conditioning dengan pelilinan 6% merupakan perlakuan yang optimum karena dapat mempertahankan mutu pepaya berdasarkan parameter mutu susut bobot, kekerasan, total padatan terlarut, kadar air, dan mampu bertahan terhadap serangan penyakit sampai akhir penyimpanan (hari ke-21). Sedangkan pepaya kontrol (tanpa VHT) dengan pelilinan maupun tanpa pelilinan hanya mampu bertahan sampai hari ke 6 karena serangan pengakit. Berdasarkan penelitian yang telah dilakukan, sebaiknya dilakukan penelitian lebih lanjut dengan tingkat keseragaman dimensi dan kematangan yang lebih tinggi dengan melakukan uji mortalitas hama dan penyakit pada pepaya khususnya lalat buah.dan pengamatan parameter mutu yang lebih lengkap seperti laju respirasi, uji mikroba, dan uji vitamin A
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

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.
