Going Beyond Counting First Authors in Author Co-citation Analysis
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
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
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
PENGARUH DIAMETER PIPA KELUAR DAN DIMENSI BAK PENAMPUNG PADA ALIRAN AIR SISTEM VACUM
Vakum merupakan suatu kondisi dari udara / gas sekitar lingkungan tertentu dimana tekanan udara dibawah tekanan atmosfir,  dimana proses sistem vakum pengambilan sumber air dari permukaan yang rendah ke tempat yang lebih tinggi dapat memberikan alternatif yang lebih efisien kepada masyarakat. Penelitian ini mempelajari pengaruh diameter pipa keluar dan dimensi bak penampung pada sistem vacum. Pembuatan sistem vacum dilakukan pada beberapa variasi yaitu variasi diameter pipa keluar dengan ukuran ½â€, ¾â€, dan 1â€. Dan variasi dimensi bak penampung dengan volume 30/40 cm, 36/40 cm, 50/80 cm, 80/120 cm, 100/120 cm,dan 120/120 cm. Dari hasil penelitian maka dapat disimpulkan bahwa diameter pipa keluar harus sama atau lebih kecil dari diameter pipa masuk agar debit yang dialirkan akan terus-menerus. Semakin besar diameter pipa keluar, semakin kecil debit air yang dihasilkan. Leher angsa berfungsi untuk mencegah udara dari luar tidak masuk ke dalam tabung yang dapat menyebabkan kekosongan di dalam tabung. Untuk mengalirkan air pada beda tinggi 2 m, maka ukuran bak penampung adalah 120/120cm, dengan pipa masuk ½â€; pipa keluar ½â€
KAJIAN PENGENDALIAN BANJIR DI KECAMATAN ILIR TIMUR I PALEMBANG
Kota Palembang terletak 100 km dari muara Sungai Musi dan Kota Palembang sangat dominan dipengaruhi oleh pasang surut. Banyak daerah di Palembang dimana tinggi elevasinya berada di bawah elevasi rata-rata muka air laut, sehingga di musim hujan banyak daerah tersebut yang menjadi rawan banjir. Ini diakibatkan oleh pengaruh pasang surut di Sungai Musi. Sebagian besar kawasan di Palembang adalah di daerah depresi, sehingga tanpa sistem drainase yang tepat kawasan yang dikontrol mengalami genangan air yang disebabkan oleh curah hujan.Palembang merupakan kota pariwisata yang memiliki program untuk meningkatkan kinerja sebagai kota aman dan menarik. Sebuah kota tepi pantai yang indah untuk dikunjungi. Oleh karena itu perlu sistem drainase yang terrencana dan terintegrasi agar tidak terjadi banjir ataupun genangan. Maka dari itu diperlukan sistem pengendalian banjir di Kota Palembang dan dalam kajian kami terutama di Kecamatan Ilir Timur I Kota Palembang.Berdasarkan hasil kajian bahwa pengendalian banjir di Kecamatan Ilir Timur I Palembang ini dapat menggunakan sistem drainase. Metode yang dipakai dalam menentukan curah hujan maksimum dengan kala ulang 10 tahun untuk wilayah kecamatan Ilir Timur I adalah Metode Gumbel dan diperoleh R=167,1 mm. Berdasarkan  Metode  Mononobe  didapat  nilai  intensitas  curah  hujan  maksimum  di  titik  7-8   yaitu I = 590,3650 mm/jam. Debit air total yang terjadi diwilayah tersebut adalah 230,288 m3/det dengan panjang saluran 23833,54 m
Dispelling the Myths Behind First-author Citation Counts
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
koamabayili/VECTRON-author-checklist: VECTRON author checklist
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
