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
Wakidi dalam Pusaran Gaya Mooi Indië dan Perannya dalam Dunia Seni Lukis di Sumatera Barat (1889-1979)
Get PDFSkripsi ini berjudul "Wakidi dalam Pusaran Gaya Mooi Indie dan Perannya dalam Dunia Seni Lukis di Sumatera Barat (1889-1979)" Penelitian dalam skripsi ini mengkaji tentang perjalan hidup Wakidi dan kiprahnya dalam dunia seni lukis serta pengaruhnya dalam dunia seni lukis di Sumatera Barat yang berlangsung antara tahun 1889 hingga tahun 1979
Penelitian ini menggunakan pendekatan biografi dengan metode penelitian sejarah yang terdiri dari empat tahapan, yakni heuristik, kritik, interpretasi dan historiografi Heuristik adalah tahapan mencari dan mengumpulkan sumber yang relevan dengan tema penelitian Sumber-sumber tersebut dapat berupa sumber primer (arsip. wawancara dengan informan yang kompeten) maupun sumber sekunder (buku, penelitian ilmiah) Kemudian dilakukan proses kritik, yakni kegiatan memverifikasi keabsahan suatu sumber yang telah dikumpulkan. Kritik dilakukan dengan dua cara yakni, kritik internal (terhadap isi dari informasi yang diperoleh) dan kritik eksternal (terhadap materi sumber yang diperoleh). Setelah dilakukan proses kritik, dilanjutkan dengan interpretasi, yakni kegiatan menyatukan pecahan-pecahan informasi yang telah disaring sebelumnya menjadi sebuah keterangan historis. Setelah selesai dengan tahapan-tahapan tersebut, baru kemudian memasuki tahapan akhir, yakni historiografi atau menuliskan informasi-informasi yang telah tersusun ke dalam bentuk tulisan ilmiah
Hasil dari penelitian ini menyimpulkan bahwa Wakidi merupakan salah satu tokoh pelukis Sumatera Barat yang telah banyak membuahkan karya, terutama lukisan- lukisan bertema pemandangan Perannya sebagai seorang guru banyak menginspirasi para pelukis muda pada zamannya sehingga di kemudian hari dapat mengembangkan kesenian lukis di Sumatera Barat. Sehingga dari bimbingan Wakidi banyak bermunculan tokoh seni lukis dari Sumatera Barat
ANALISIS SUSEPTIBILITAS MAGNETIK TANAH LAPISAN ATAS SEBAGAI INDIKATOR BENCANA LONGSOR DI BUKIT SULA KECAMATAN TALAWI KOTA SAWAHLUNTO
Get PDFTelah dilakukan penelitian mengenai analisis suseptibilitas magnetik tanah lapisan atas sebagai indikator bencana longsor di Bukit Sula Kecamatan Talawi Kota Sawahlunto. Sampel tanah diambil dari dua lokasi di Bukit Sula, yaitu lokasi bervegetasi (lokasi A) dan lokasi tanpa vegetasi (lokasi B). Pengambilan sampel vertikal ke bawah masing-masing sepanjang 100 m dengan jarak spasi 5,0 m, sehingga diperoleh 42 titik pengambilan sampel pada kedua lokasi tersebut. Pengukuran nilai suseptibilitas magnetik menggunakan Bartington Magnetic Suseptibility Meter yang diukur pada dua frekuensi, yaitu low frequency 0,465 kHz (χLF) dan high frequency 4,65kHz (χHF). Pada lokasi A nilai χLF rata-rata yang diperoleh yaitu 804,05×10-8 m3kg-1, sedangkan nilai χHF rata-rata yaitu 804,25×10-8 m3kg-1. Pada lokasi B nilai χLF rata-rata yang diperoleh yaitu 9,85×10-8 m3kg-1, sedangkan nilai χHF rata-rata yaitu 9,64×10-8 m3kg-1. Hasil pengujian XRF menunjukkan bahwa mineral magnetik yang terdapat pada sampel di kedua lokasi yaitu hematit (Fe2O3). Berdasarkan perbandingan nilai suseptibilitas dan konsentrasi mineral hematit dan kuarsa antara sampel lokasi A dan lokasi B, dapat dikatakan bahwa lokasi B telah mengalami erosi. Berdasarkan keberadaan bulir superparamagnetik, sampel lokasi B memiliki butiran lebih halus dibandingkan sampel lokasi A. Hal ini disebabkan karena lokasi B merupakan daerah tanpa vegetasi, sehingga menyebabkan air hujan langsung masuk ke dalam tanah dan dapat menurunkan tingkat kelekatan butiran tanah. Oleh karena itu, lokasi B lebih besar kemungkinan terjadinya bencana longsor dibandingkan dengan lokasi A.

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
