Going Beyond Counting First Authors in Author Co-citation Analysis
No full textThe 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
Peningkatan Kinerja Pengisian Baterai Panel Surya Pada Electric Vehicle Charging Station System Berbasis Kombinasi Algoritma Kontrol Mppt-Avpso Dan Proportional Integral
No full textKendaraan listrik atau EV adalah bukti konkrit tumbuhnya kesadaran manusia dalam menjaga iklim bumi. Peningkatan penggunaan kendaraan listrik turut membuat stasiun pengisian daya atau charging station menjadi permasalahan baru bagi jaringan listrik PLN. Melihat permasalahan tersebut, diperlukan sebuah sistem charging yang tepat dengan memanfaatkan sumber energi terbarukan. Pembangkit Listrik Tenaga Surya (PLTS) adalah sumber energi listrik yang hijau dan terbarukan yang belum dapat dioptimalkan dengan baik dan masih memiliki banyak kendala ketika diterapkan pada sistem charging station. Terdapat beberapa hal yang dapat mepengaruhi tingkat kinerja pada PLTS charging station, salah satunya adalah metode kontrol yang digunakan. Metode algoritma AVPSO dan kontrol PI digunakan pada sistem PLTS untuk mendapatkan posisi keluaran daya yang paling maksimal maupun untuk mengatur keluaran arus dan tegangan secara konstan. Metode kontrol memegang peranan penting pada charging station khususnya untuk meningkatkan efisiensi, kesehatan, dan kualitas charging pada baterai secara proporsional. Berbagai penelitian telah dilakukan seperti membatasi energi yang diproduksi, memberi pengaman LVD dan OVD, hingga mengombinasi atau memadukan beberapa metode kontrol. Melihat Pentingnya fungsi kontrol, penelitian ini berfokus memadukan algoritma AVPSO dengan metode kontrol PI. Beberapa algoritma kontrol akan aktif secara bergantian melalui perhitungan coulomb counting dan bekerja secara adaptif menyesuaikan kondisi baterai. Berdasarkan uji lapangan, disimpulkan jika kombinasi algoritma AVPSO dan kontrol PI telah bekerja sesuai target yang ditentukan khususnya ketika baterai telah mencapai SOC 85%. Algoritma AVPSO mampu menaikkan keluaran daya panel surya hingga 13.64% lebih tinggi dibandingkan keluaran daya panel surya yang dihubungkan langsung ke baterai. Kontrol PI yang digunakan juga mampu menjaga nilai tegangan charging baterai hingga 74.12% lebih akurat dibanding sistem tanpa kontrol. Oleh karena itu, dapat disimpulkan jika rancang bangun sistem yang dibuat telah berhasil menyelesaikan rumusan permasalahan yaitu meningkatkan kinerja sistem pengisian baterai panel surya pada electric vehicle charging station.

EVs are concrete evidence of the growing human awareness in maintaining the earth's climate. The increase in the use of electric vehicles has also made charging stations a new problem for the PLN electricity network. Seeing these problems, we need an appropriate charging system by utilizing renewable energy sources. Solar Power Plants (PLTS) are green and renewable sources of electrical energy that cannot be optimized properly and still have many obstacles when applied to the charging station system. There are several things that can affect the performance level of the PLTS charging station, one of which is the control method used. The AVPSO algorithm method and PI control are used in the PV mini-grid system to get the maximum power output position as well as to adjust the current and voltage output constantly. The control method plays an important role in the charging station, especially to increase the efficiency, health, and quality of charging the battery proportionally. Various studies have been carried out such as limiting the energy produced, providing LVD and OVD protection, to combining or combining several control methods. Seeing the importance of the control function, this research focuses on combining the AVPSO algorithm with the PI control method. Several control algorithms will be active alternately through coulomb counting and work adaptively to adjust battery conditions. Based on field tests, it is concluded that the combination of AVPSO algorithm and PI control has worked according to the specified target, especially when the battery has reached 85% SOC. The AVPSO algorithm is able to increase the power output of solar panels up to 13.64% higher than the power output of solar panels that are connected directly to the battery. The PI control used is also able to keep the battery charging voltage value up to 74.12% more accurate than the system without control. Therefore, it can be concluded that the system design has succeeded in solving the problem formulation, namely improving the performance of the solar panel battery charging system at the electric vehicle charging station
Variations on the Author
No full text“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 textWe 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
No full textWe 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.
