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
DAMPAK REUNI AKBAR 212 TERHADAP ABNORMAL RETURN SAHAM PADA KELOMPOK INDEKS SAHAM LQ-45
Get PDFABSTRAK
Sri Lindayani. Dampak Reuni Akbar 212 Terhadap Abnormal Return Saham Pada Kelompok Indeks Saham LQ-45. 2020.
Pengujian terhadap kandungan informasi pada peristiwa reuni akbar 212 tanggal 2 Desember 2019 terhadap aktivitas bursa efek ini dimaksudkan untuk melihat reaksi pasar terhadap reuni akbar 212 tanggal 2 Desember 2019 yang dapat diukur dengan abnormal return. Pengujian kandungan informasi dimaksudkan untuk melihat reaksi dari suatu peristiwa. Jika peristiwa tersebut terdapat kandungan informasi maka, diharapkan pasar dapat bereaksi pada waktu peristiwa tersebut diterima oleh pasar. Reaksi pasar ditunjukkan dengan adanya fluktuasi harga saham. Reaksi ini dapat diukur dengan menggunakan return sebagai nilai perubahan harga atau dengan menggunakan abnormal return. Jika menggunakan abnormal return maka dapat dikatakan bahwa suatu peristiwa yang mempunyai kandungan informasi akan memberikan abnormal return kepada pasar. Sebaliknya yang tidak mengandung informasi tidak akan memberikan abnormal return kepada pasar.
Metode dalam penelitian ini berbentuk metode penelitian kuantitatif. Sedangkan metode analisis data yang digunakan adalah analisis diskripsi data penelitian, uji normalitas, dan uji hipotesis.
Hasil penelitian ini membuktikan bahwa dari hasil pengujian Paired-Sample T Test terhadap abnormal return antara sebelum dan sesudah peristiwa Reuni Akbar 212 menunjukkan bahwa H0 diterima, karena hasil uji statistik menunjukkan probabilitas sebesar 0,371. Probabilitas yang diperoleh lebih besar dari 0,05.
Kesimpulan penelitian ini adalah tidak ada perbedaan yang signifikan abnormal return pada perusahaan LQ 45 yang terdaftar di Bursa Efek Indonesia antara sebelum dan sesudah peristiwa Reuni Akbar 212. Dengan demikian hipotesis yang menyatakan “terdapat pengaruh peristiwa Reuni Akbar 212 terhadap abnormal return saham pada kelompok indeks saham LQ-45” tidak dapat diterima kebenarannya.
Kata Kunci : Peristiwa Reuni Akbar 212, Abnormal Return Saham

ABSTRACT
Sri Lindayani. The Impact of the 212 Great Reunion on Abnormal Stock Returns on the LQ-45 Stock Index Group. Thesis. Tegal: Faculty of Economics and Business. Pancasakti University, Tegal. 2020
Testing of the information content of the 212 grand reunion event on 2 December 2019 on the activity of the stock exchange is intended to see the market reaction to the 212 grand reunion on 2 December 2019 that can be measured by abnormal return. Testing the information content is intended to see the reaction of an event. If the event contains information then it is expected that the market can react when the event is received by the market. Market reaction is indicated by fluctuations in stock prices. This reaction can be measured using returns as the value of price changes or by using abnormal returns. If you use abnormal returns, it can be said that an event that has information content will provide an abnormal return to the market. Conversely that does not contain information will not provide abnormal returns to the market.
The method in this research is quantitative research methods. While the data analysis method used is a research data analysis description, normality test, and hypothesis testing.
The results of this study prove that the results of the Paired-Sample T Test for abnormal returns between before and after the Great Reunion event 212 showed that H0 was accepted, because the statistical test results showed a probability of 0.371. The probability obtained is greater than 0.05.
The conclusion of this study is that there is no significant difference in abnormal return on LQ 45 companies listed on the Indonesia Stock Exchange between before and after the Great Reunion event 212. Thus the hypothesis stating "there is an influence of the Great Reunion event 212 on abnormal stock returns in the stock index group LQ-45 "cannot be accepted as correct.

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
