    Going Beyond Counting First Authors in Author Co-citation Analysis

    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

    No full text
    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

    Indonesia berada diposisi kedua dengan jumlah tanaman obat asli tertinggi di dunia setelah Hutan Hujan Amazon. G. pictum (L) Griff   merupakan salah satu etnomedisin yang telah dimanfaatkan secara luas oleh masyarakat Indonesia, tapi keragaman genetiknya belum dipetakan. Penelitian ini bertujuan menganalisis keragaman genetik G. pictum (L) Griff   dari Indonesia Bagian Timur berdasarkan marka molekuler SRAP melalui pencarian keberadaan polimorfisme. G. pictum (L) Griff   yang digunakan berasal dari 11 etnis Indonesia Timur yang sudah dikeringkan sebelumnya, kemudian dilakukan isolasi DNA kromosom, amplifikasi PCR dengan menggunakan 8 kombinasi primer SRAP terpilih, kemudian dianalisis kekerabatan dari 7 etnis menggunakan software NTSYS (Numerical Taxonomy and Multivariative Analysis System) 2.0 dan PopGene (Population Genetic Analysis) 1.3. Dari hasil penelitian diperoleh nilai Persen Lokus Polimorfik (PLP) sebesar 88.55% dengan total lokus ditemukan 49 (44 lokus poliformik dan 5 lokus monomorfik), dan variasi Indonesia menduduki peringkat kedua dengan jumlah tanaman obat asli tertinggi di dunia setelah Hutan Hujan Amazon. Handeuleum (G. pictum (L) Griff) merupakan salah satu tanaman obat yang telah dimanfaatkan secara luas oleh masyarakat Indonesia, namun informasi mengenai keragaman genetiknya masih terbatas. Penelitian ini bertujuan untuk memperoleh informasi mengenai keragaman genetik 52 aksesi G. pictum (L) Griff dari 11 etnis Indonesia Bagian Timur berdasarkan marka molekuler SRAP. Penelitian ini dilaksanakan pada bulan November 2018 hingga Januari 2019. Sebanyak 52 aksesi G. pictum (L) Griff dan 16 kombinasi primer SRAP digunakan dalam penelitian ini. Analisis kekerabatan dilakukan berdasarkan nilai indeks similaritas dan konstruksi dendogram dengan menggunakan program NTSYS 2.0 dan PopGene 1.3. Sebanyak 49 lokus (44 lokus polimorfik dan 5 lokus monomorfik) diperoleh dari delapan kombinasi primer terpilih dengan presentase polimorfik sebesar 88.55%. Keragaman genetik antar aksesi tergolong tinggi (86%) sedangkan antar etnis tergolong rendah (47.23%). Etnis dengan keragaman tertinggi adalah Demta (81.63%), sedangkan Auyu adalah Etnis dengan keragaman genetik yang paling rendah (2.04%). Berdasarkan nilai Indeks Dissimilarity (ID) atau nilai keragaman yang menunjukkan tingkat kekerabatan, Etnis Bajawa dan Auyu memiliki tingkat kekerabatan terjauh (ID = 1.0720). Informasi yang dihasilkan dalam penelitian ini bermanfaat untuk mendukung program pemuliaan dan konservasi daun wungu. Kata kunci: dendogram, handeuleum, SRAP, tanaman obatIndonesia is in second after the Amazon Rainforest, with the world’s highest number of endemic medicinal plants. Handeuleum (Graptophyllum pictum (L.) Griff) is one of the medicinal plants which Indonesian people have widely used. However, information on its genetic diversity is still lacking. This study aimed to achieve information about the genetic diversity of 52-accessions of G. pictum (L.) Griff from 11 Eastern Indonesia ethnics based on SRAP molecular marker. This study was conducted from November 2018 to January 2019. Fifty-two accessions of G. pictum (L.) Griff and 16 combinations of SRAP primers were used in this research. Diversity analysis was carried out based on the similarity index and dendrogram using NTSYS 2.0 program and PopGen 1.3. Forty-nine loci (44 polymorphic loci and five monomorphic loci) were found by using eight selected primer combinations with a percentage of polymorphic was 88.55%. The diversity between accessions was high (86%); meanwhile, between ethnicities was low (47.23%). Demta ethnicity had the highest diversity (81.63%), while Auyu had the lowest (2.04%). According to the dissimilarity index (DI) or diversity value which showed the kinship level, Bajawa and Auyu have the farthest kinship (DI = 1.0720). Therefore, the information in this research may benefit for supporting breeding programs and conservations of handeuleum. Keywords: dendrogram, handeuleum, medicinal plants, SRA

    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

    koamabayili/VECTRON-author-checklist: VECTRON author checklist

    No full text
    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

    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.
