    The 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

    “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

    We 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

    We 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

    We 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

    Efektivitas daun kemangi sebagai anti lalat pada pembuatan ikan asin sepat rawa (Trichopodus trichopterus): The effectiveness of lemon basil as a fly repellent in salted fish from three spot gourami (Trichopodus trichopterus)

    Kontaminasi lalat dapat terjadi selama proses pengeringan ikan asin. Pemberian insektisida alami merupakan salah satu pencegahan lalat selama pembuatan ikan asin. Penelitian ini bertujuan untuk menentukan efektivitas daun kemangi (larutan maupun ekstrak) sebagai anti lalat pada pembuatan ikan asin. Penelitian dilakukan secara bertahap, yaitu pembuatan larutan dan ekstrak serta pembuatan ikan asin. Jenis ikan yang digunakan dalam pembuatan ikan asin yaitu ikan sepat dengan tiga perlakuan yaitu tanpa filtrat/ekstrak kemangi (P1), perendaman filtrat kemangi 10% (P2), dan penyemprotan ekstrak kemangi 10% (P3). Pengamatan dilakukan 3 kali ulangan pada setiap parameter yaitu jumlah lalat dan suhu. Uji kelembapan dilakukan selama penjemuran ikan dan uji mortalitas dilakukan terhadap larva lalat. Hasil penelitian menunjukkan bahwa larutan kemangi/filtrat yang diperoleh sebanyak 64,09% dan setelah dipekatkan menghasilkan ekstrak sebesar 32,62%. Total lalat yang hinggap yaitu ikan asin kontrol 105, direndam dalam larutan 63 dan disemprot ekstrak selama penjemuran yaitu 33 ekor. Rata-rata lalat aktif hinggap pada ikan asin dengan suhu 29-36℃ dan kelembapan 55-69%. Larva lalat hanya mengalami kematian pada perlakuan penyemprotan ekstrak kemangi 10%. Perlakuan penyemprotan ekstrak daun kemangi efektif digunakan untuk pencegahan lalat dibandingkan perendaman larutan daun kemangi.  Fly contamination may arise during the drying of salted fish. Offering natural insecticides can be an effective means of deterring flies from infesting salted fishes. This study aimed to determine the effectiveness of basil leaves (solution and extract) as fly repellents in salted fish. The study proceeded in a series of stages, namely the preparation of solutions and extracts, and the production of salted fish. The salted fish used in this study comprised three-spot gourami fish, which were subjected to three different treatments: a control group without basil filtrate or extract (P1), a group soaked in 10% basil filtrate (P2), and a group sprayed with 10% basil extract (P3). Three observations were conducted for each parameter, specifically the quantity of flies, and temperature and humidity assessments were conducted during the drying process of the fish, while mortality evaluations were carried out on the fly larvae. The study outcomes indicated that the basil solution/filtrate obtained had a yield of 64.09%, and after being concentrated, it produced an extract with a concentration of 32.62%. The specific quantity of flies that arrived, comprising 105 control salted fish immersed in 63 different solutions and sprayed with an extract during the drying process, amounted to 33. The typical temperature range for active flies to land on salted fish is–29-36℃, with a corresponding humidity level of 55-69%. The fly larvae were observed to perish only when subjected to the application of 10% basil extract. The application of basil leaf extract via spraying was more effective in thwarting fly infestations than by immersing the leaves in a solution

    Author Under Sail The Imagination of Jack London, 1893-1902

    No full text
    In 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.
