Going Beyond Counting First Authors in Author Co-citation Analysis
Get PDFThe 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
Get PDF“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
Get PDFWe 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
Oxidasi Biologi, Radikal Bebas, dan Antioxidant
Get PDFIntroductions : Aerobic metabolism process induces production of free radicals (ROS) 2.5% of oxygen consumption or about 3.4 kg/24 hours.  Content : Stressor likes ultraviolet radiation, hypoxia, hyperoxia, pollutant, and other chemical substances could induce ROS production. Stressor also stimulates secretion of antioxidant enzymatic such as catalase, hydropheroxidase, and superoxide dismutase. The ROS produced will disturb homeostasis or stimulate cell growth, dependent on the level of ROS. When the ROS level is overwhelm the antioxidant capacity, cell leading to undergo oxidative stress. If the ROS level and antioxidant capacities are equilibrium, it leading to cell growth. Other resources of ROS result from biologic oxidation reaction particularly from mitochondria. To scavenge ROS, cell has provided several antioxidants water and lipid soluble both enzymatic and non-enzymatic.Conclusion : The ROS is produced in aerobically life resulted from oxidative phosphorilations chain reaction. Cell provides the antioxidant both enzymatic and non-enzymatic in order to scavenge it.           Keywords : Biologic oxidation, ROS, Antioxidant
Pengkajian resep secara administratif pada resep dokter spesialis saraf di Apotek Magetan
Get PDFPengkajian resep secara administratif penting untuk dilakukan karena memuat keabsahan dan kejelasan suatu resep, sehingga dapat mencegah terjadinya medication error. Penelitian ini bertujuan untuk mengetahui pengkajian resep secara administratif pada resep dokter spesialis saraf di Apotek Magetan periode Januari 2020. Penelitian yang dilakukan bersifat deskriptif dan pengambilan data dilakukan secara retrospektif. Metode pengambilan sampel menggunakan metode simple random sampling, terhadap 200 lembar resep. Hasil pengamatan menunjukkan persentase ketidaklengkapan resep dokter spesialis saraf di Apotek Magetan yaitu alamat pasien 100%, umur pasien 98,5%, jenis kelamin 100%, berat badan 99,5%, sedangkan nama dokter, alamat dokter, SIP, paraf dokter, tanggal penulisan resep, nomor telepon dokter, dan nama pasien yang dituliskan oleh dokter spesialis saraf telah mencapai 100%. Resep dokter spesialis saraf di Apotek Magetan menurut Permenkes RI No. 73 tahun 2016 belum memenuhi ketentuan kelengkapan resep secara administratif
Dispelling the Myths Behind First-author Citation Counts
Get PDFWe 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
