    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

    In an effort to achieve optimal agricultural productivity, efficiency in each stage of cultivation is a determining factor. One important stage is seed planting and fertilization, which are traditionally still carried out separately. This study aims to develop a seed planting and fertilization tool that is integrated in one unit, as an effort to improve the efficiency, effectiveness, and sustainability of the planting and fertilization process on agricultural land. This tool is designed with an integrated engineering approach, which allows seed planting and fertilizer application to be carried out simultaneously in one operation. The study was conducted with a series of systematic stages, starting from a literature study to identify needs and challenges in conventional agricultural practices. Furthermore, the concept design of the tool was carried out followed by the creation of a physical prototype made of strong and durable materials. Prototype performance testing was carried out on experimental land with various types of soil and environmental conditions to measure time and energy efficiency, accuracy of seed and fertilizer placement, and plant growth results. The results of the study showed that the developed tool was able to significantly increase time and energy efficiency compared to conventional planting and fertilization methods. In addition, this tool provides more uniform results in seed and fertilizer placement, which has a positive impact on plant growth and yields. The implication of this research is the creation of agricultural technology innovations that can support sustainable agricultural practices, reduce dependence on manual labor, and increase farmer productivity. This tool has the potential to be a solution to modern agricultural challenges, especially in efforts to achieve food security and environmental sustainability.Dalam upaya mencapai produktivitas pertanian yang optimal, efisiensi dalam setiap tahapan budidaya menjadi faktor penentu. Salah satu tahapan penting adalah penanaman benih dan pemupukan, yang secara tradisional masih dilakukan secara terpisah. Penelitian ini bertujuan untuk mengembangkan suatu alat penanaman benih dan pemupukan yang terintegrasi dalam satu unit, sebagai upaya untuk meningkatkan efisiensi, efektivitas, dan keberlanjutan proses penanaman serta pemupukan pada lahan pertanian. Alat ini dirancang dengan pendekatan rekayasa terpadu, yang memungkinkan penanaman benih dan pemberian pupuk dilakukan secara simultan dalam satu kali operasi. Penelitian dilakukan dengan serangkaian tahapan yang sistematis, dimulai dari studi literatur untuk mengidentifikasi kebutuhan dan tantangan dalam praktik pertanian konvensional. Selanjutnya, dilakukan perancangan konsep alat diikuti dengan pembuatan prototipe fisik yang terbuat dari material yang kuat dan tahan lama. Pengujian kinerja prototipe dilakukan di lahan percobaan dengan berbagai jenis tanah dan kondisi lingkungan untuk mengukur efisiensi waktu dan tenaga, akurasi penempatan benih dan pupuk, serta hasil pertumbuhan tanaman. Hasil penelitian menunjukkan bahwa alat yang dikembangkan mampu meningkatkan efisiensi waktu dan tenaga secara signifikan dibandingkan metode penanaman dan pemupukan konvensional. Selain itu, alat ini memberikan hasil yang lebih seragam dalam penempatan benih dan pupuk, yang berdampak positif pada pertumbuhan dan hasil panen tanaman. Implikasi dari penelitian ini adalah terciptanya inovasi teknologi pertanian yang dapat mendukung praktik pertanian berkelanjutan, mengurangi ketergantungan pada tenaga kerja manual, dan meningkatkan produktivitas petani. Alat ini berpotensi menjadi solusi bagi tantangan pertanian modern, khususnya dalam upaya mencapai ketahanan pangan dan keberlanjutan lingkungan. &nbsp

    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

    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.
