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
Variabilitas Dan Tipe Iklim Di Sumedang
No full textLoka Pengamatan Dirgantara Sumedang berada di desa Haurngombong Kecamatan Pamulihan Kabupaten Sumedang yang merupakan daerah pengembangan pertanian. Keberadaaan LPD Sumedang di Kecamatan Pamulihan menjadi strategis sebagai sumber informasi iklim untuk pengembangan pertanian. Tujuan dari penulisan makalah ini untuk memberikan informasi tentang variabilitas dan tipe iklim di sekitar LPD Sumedang. Data yang digunakan meliputi data curah hujan, suhu, kelembapan udara dan lama penyinaran. Data curah hujan merupakan hasil pengamatan dan perekaman dari 1983-2012. Metode analisis yang digunakan ukuran pemusatan dan klasifikasi iklim menurut Oldeman. Curah hujan rata-rata bulanan pada bulan Juni-September di bawah 100 mm/bulan (bulan kering) sedangkan Nopember-April di atas 200 mm/bulan (bulan basah). Curah hujan maksimum dalam setahun mencapai 3800 mm/tahun pada 2010 dan minimum sebesar 1100 mm/tahun pada 1997. Rata-rata suhu udara selama setahun yaitu pagi sekitar 20,8oC, siang 27,9oC, dan sore hari 26,0oC, dengan rata-rata harian 23,7oC. Rata-rata kelembapan udara selama setahun yaitu pagi sekitar 79,7%, siang 46,6%, dan sore hari 57,1%, dengan rata-rata harian 65,8%. Klasifikasi Oldeman menggambarkan tipe iklim disekitar wilayah LPD Sumedang yaitu C3. Kelompok ini mempunyai karakter hanya dapat satu kali tanam padi dan dua kali tanam palawija.Hlm. 1-
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
Kajian Wilayah Rawan Kekeringan Di Indonesia Dengan Menggunakan Data Satelit MTSAT
No full textThe use MTSAT satellite data in this research is based on the following things to the limited number of observation stations, incomplete data, inaccurate data due to recording errors and damaged equipment, as well as obtain data relatively old or not in real time, while remote sensing data has the coverage area extensive, high temporal resolution. The purpose of this study was to assess the drought vulnerability areas in Indonesia based on MTSAT satellite data. The targets to be achieved i.e. information obtained the level meteorological drought in Indonesia based on MTSAT satellite data. The calculation of drought method used Standardized Precipitation Index (SPI). This method measures the lack of rainfall in different periods under normal conditions. Meanwhile, rainfall estimates are based on cloud top temperature and cloud cover percentage. The results obtained are highly variable rainfall and gained some value in a day of extreme rainfall reached 100 mm or more. Range dominant daily rainfall from 0-50 mm. While the category of high-intensity rainfall is also often appear with valuesranging 51-100 mm. Estimation of rainfall from satellite data tend to under estimate for all locations in Indonesia. The value is very different than shown in the region near the equator. Low SPI values less than -1 as an indicator of drought continue to repeat both the time and place in the island of Java to East Nusa Tenggara, southern of Kalimantan, southeastern and southern of Sulawesi.Hal. 227-23
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
