    Going Beyond Counting First Authors in Author Co-citation Analysis

    Full text link
    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

    Design Of A High-Current Low-Voltage Power Supply System Using MOT (Microwave Oven Transformers) in Spot Welding Applications

    This study aims to design and develop a high-current, low-voltage power supply system using a modified Microwave Oven Transformer (MOT) for spot welding applications. The system was designed by modifying the secondary winding of the MOT to reduce the output voltage and increase the output current, while also implementing a rectifier circuit and filter capacitors to produce a stable DC output. The research employed an experimental method with a quantitative approach, involving variations in current (30%–99%) and welding duration (10–50 ms) to observe their effects on electrical parameters (final current and voltage) as well as the strength of weld joints on Nickel Strip material. Test results showed that increasing the current led to higher output current and voltage. The optimal weld strength was achieved at 60%–80% current, with the welded joint capable of withstanding loads up to 8,000 grams. At the highest current (99%), the joint strength reached 16,000 grams but showed signs of failure due to overheating. In conclusion, the MOT-based power supply system was successfully developed to produce a stable high DC current suitable for spot welding. The system is considered feasible for light welding applications and small-scale industrial prototypes, with a recommendation to integrate a cooling mechanism to enhance its durability during extended operation.83 PagesSkripsi Sarjan

    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

    Full text link
    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

    Full text link
    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

    Permasalahan narkotika semakin lama semakin meningkat, narkotika sudah menjadi persoalan nasional bahkan Internasional karena  dampak yang ditimbulkan dari Narkotika sampai merambah ke kalangan anak–anak, remaja bahkan orang tua. Narkotika beredar di diskotik, karoke, plaza–plaza, dikampus maupun di sekolah–sekolah. Bahkan Narkoba sudah merambah mulai dari kota – kota besar sampai ke pedesaan. Sesuai dengan Undang–Undang Nomor. 13 tahun 1961 kemudian berubah menjadi Undang–Undang Nomor 2 Tahun 2002 tentang Tugas Pokok Polri selaku Pengayom, Pelindung dan Pelayan Masyarakat wajib untuk memberantas penyakit masyarakat yaitu masalah narkoba. Narkoba sudah merambah mulai dari kota–kota besar sampai ke pedesaan. Penyalahgunaan narkotika sudah menjadi masalah yang umum yang terjadi di masyarakat, oleh karena itu setiap masyarakat diharapkan partisipasinya dalam menganggulangi bahaya narkotika. Polisi sebagai pengayom masyarakat harus dapat memberantas pelaku tindak pidana narkotika, mulai dari jaringan kecil sampai ke jaringan besar seperti  bandar narkoba dan menangkap pelaku tindak pidana narkoba

    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
