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
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
Analisis Potensi Energi Listrik Ditinjau dari Energi Hidro di Minahasa Selatan
Get PDFAbstrak — Penelitian ini dilakukan dengan tujuan untuk menghitung penurunan daya listrik yang dapat dihasilkan oleh Pembangkit Listrik Tenaga Mikro Hidro yang ada di Sungai Ongkaw. Penurunan daya listrik pada PLTMH sungai Ongkaw ini diakibatkan oleh adanya sedimen yang menumpuk pada bendung PLTMH, sehingga berkurangnya debit air yang dapat dialirkan ke pipa penstock untuk membangkitkan daya listrik. Dalam penelitian ini, dilakukan perhitungan debit andalan Sungai Ongkaw yang didapat dari pengolahan data debit Sungai Ongkaw selama 3 bulan dengan menggunakan metode FDC (Flow Duration Curve), perhitungan daya listrik terbangkit dari debit rencana pada PLTMH Ongkaw, perhitungan penurunan daya listrik pada PLTMH Ongkaw. Dari hasil penelitian, didapat nilai debit rencana PLTMH Ongkaw adalah sebesar 0,2565 m3/s dengan daya terbangkit sebesar 2,3742 kW. Penurunan daya dihitung berdasarkan pengukuran yang dilakukan sebanyak 2 kali. Pada debit terukur sungai sebesar 1,1923 m3/s, air yang dapat dialirkan ke pipa setinggi 7 cm menghasilkan debit sebesar 0,0592 m3/s. Daya yang dapat dihasilkan sebesar 1,2326 kW atau sebesar 56,12% dari rencana daya terbangkit. Pada debit terukur sungai sebesar 0,5788 m3/s, air yang dapat dialirkan ke pipa setinggi 4 cm menghasilkan debit sebesar 0,0189 m3/s. Daya tidak dapat lagi dihasilkan karena debit tersebut tidak dapat lagi memutar turbin
Penerapan Sistem Proteksi Arus Bocor pada Instalasi Listrik Rumah Tinggal
Get PDFThis study focuses specifically on household needs because electricity is an inseparable part of daily needs. The problems identified are how the protection system uses the earth-leakage circuit breaker (ELCB) model for residential installations and how to apply it in residential homes quickly and straightforwardly. In the current protection system, the built system must work in the range of < 30 mA according to the general requirements of electrical installations (in Indonesian abbreviated: PUIL) when the muscles cannot release the conductor or are dangerous. The test results of ELCB enhancements can be applied in residential homes and thus can be helpful for the community in avoiding short circuits and fires. The conclusion is that the resistance measurement for the 21 participants went well, and the average resistance value was 3665 kΩ. Thus the tool on the simulator works according to the operation according to PUIL.
Abstrak— Kajian ini lebih memfokuskan secara khusus untuk kepentingan rumah tangga, karena listrik menjadi hal yang tak terpisahkan dalam kebutuhan sehari-hari. Masalah yang dapat diidentifikasi adalah bagaimana sistem proteksi menggunakan model earth-leakage circuit breaker (ELCB), untuk instalasi rumah tinggal, dan bagaimana cara penerapannya di rumah tinggal secara mudah dan sederhana. Pada sistem proteksi arus sistem yang dibangun harus bekerja pada rentang < 30 mA menurut persyaratan umum instalasi listrik (PUIL), merupakan saat dimana otot tidak sanggup melepaskan penghantar atau berbahaya. Hasil pengujian piranti tambahan ELCB dapat diterapkan di rumah tinggal dan dengan demikian dapat berguna bagi masyarakat dalam menghindari hubung singkat dan kebakaran. Kesimpulan pengukuran tahanan untuk para partisipan berjumlah 21 orang berjalan dengan baik dan diperoleh nilai tahanan rata-rata 3665 kΩ. Dengan demikian alat pada simulator bekerja sesuai dengan operasi menurut PUIL
