Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe 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
Full text link“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
Full text linkWe 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

ABSTRAK
Keandalan sistem tenaga listrik dapat didefinisikan sebagai suatu kemampuan dari sistem tersebut untuk memberikan pasokan tenaga listrik yang cukup dengan kualitas yang memuaskan. Semakin meningkatnya kebutuhan tenaga listrik, maka tuntutan pada sistem tenaga listrik yang memiliki keandalan dalam penyediaan dan penyaluran daya pada jaringan distribusi. Indeks-indeks yang digunakan untuk mengetahui tingkat pada keandalan sistem distribusi antara lain adalah indeks SAIFI dan SAIDI. Penelitian ini bertujuan untuk mengevaluasi keandalan sistem jaringan distribusi PT. PLN Kota Tanjung Kalimantan Selatan melakukan upaya peningkatan indeks keandalan pada feeder TJ 02 Gardu Induk Tanjung. Metode yang dalam penelitian ini menggunakan Metode RNEA untuk menentukan indeks keandalan dengan pendekatan Ekuivalen menggunakan keandalan jaringan untuk menganalis sistem distribusi radial yang besar dan kompleks secara sederhana. Dengan menggunakan pendekatan berulang dan berurutan untuk mengevaluasi indeks keandalan per titik beban (load point). Penelitian pada feeder TJ 02 Gardu Induk Tanjung, mendapatkan hasil indeks SAIFI 3,396 (kali/pelanggan/tahun) dan SAIDI 9,936 (jam/pelanggan/tahun) sedangkan dengan Software ETAP mendapatkan hasil indeks SAIFI 3,492 (kali/pelanggan/tahun) dan SAIDI 10,074 (jam/pelanggan/tahun) Untuk meningkatkan keandalan dilakukan implementasi Recloser pada sistem dan diperoleh indeks keandalan SAIFI 3,167 (kali/pelanggan/tahun) dan SAIDI 7,791 (jam/pelanggan/tahun).

ABSTRACT
A reliability of electric power system can be defined as a system ability to provide sufficient electricity supply with satisfactory quality. The increasing demand for electricity requires electric power system that possess realibility of the supply and power distribution in the distribution network. While indices used to determine the level of distribution system reliability in this study are the SAIFI and SAIDI indices. This study aims to evaluate the reliability of the distribution network system of PT. PLN Tanjung City in South Kalimantan by improving the reliability index of the TJ 02 Tanjung Substation Feeder. Method applied in this study is the RNEA method to determine the reliability index with an equivalent approach using network reliability to analyze large and complex radial distribution systems in a simple way by using a repetitive and sequential approach to evaluate the reliability index per load point. Research on TJ 02 Tanjung Substation Feeder with the RNEA method obtains SAIFI index result of 3,396 (times/ customers/year) and SAIDI index result of 9,936 (hours/customers/year) whereas ETAP Software get SAIFI index result of 3,492 (times/customers/years) and SAIDI index result of 10,074 (hours/customers/year). To improve its reliability the recloser was implemented on the system and the SAIFI reliability index was obtained 3,167 (times/customers/years) and SAIDI 7,791 (hours/customers/years).
