Going Beyond Counting First Authors in Author Co-citation Analysis
No full textThe 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
No full text“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
No full textWe 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
Dispelling the Myths Behind First-author Citation Counts
No full textWe 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

Pengaruh Frekuensi Rapat dan Partisipasi Dewan Direksi Terhadap Nilai Perusahaan
No full textABSTRACT
One way to measure the effectiveness of board of directors supervision activities is by evaluating the meeting activities periodically. This study seeks to broaden previous research that empirically investigates the influence of board meetings frequency, joint meeting with the board of commissioners and the level of board of directors participation in meetings on firm performance. The firm’s performance is measured through the firm’s profitability ratio and firm’s value. The model developed in this study also integrates control variable of firm characteristics. This study took 117 samples of companies that were listed on the Indonesia Stock Exchange during the period 2015-2018. The result of this study explain that the participation of the board of directors in joint meetings was not proven to have a significant effect on profitability, but by using the DAR and LnTA as control variable shows that only the participation of the board of directors at a joint meeting with the commissioner proved to have an effect on the firm’s profitability. This result shows that the strategic meeting between directors and commissioners has an influence on companies with relativily large asset values. Frequency of directors meetings and joint meetings with commissioners was not proven to have an impact on firm profitability. Meanwhile with the firm’s value, the frequency of joint meeting between the directors and commissioners has a significant influence on the firm’s value. Meanwhile, directors participation in meetings, both directors and joint meetings, does not affect the firm’s value.
ABSTRAK
Salah satu cara untuk mengukur efektivitas kegiatan pengarahan dan pengawasan oleh dewan direksi perusahaan adalah dengan mengevaluasi kegiatan rapat yang mereka lakukan secara periodik. Penelitian ini berupaya untuk memperluas penelitian sebelumnya yang menyelidiki secara empiris pengaruh dari frekuensi rapat dewan direksi, rapat gabungan direksi dengan dewan komisaris serta tingkat partisipasi dewan direksi dalam kegiatan rapat direksi dan rapat gabungan terhadap kinerja perusahaan. Kinerja perusahaan diukur melalui rasio profitabilitas perusahaan serta pengukuran atas nilai perusahaan. Model yang dikembangkan dalam penelitian ini juga mengintegrasikan variabel kontrol karakteristik perusahaan. Penelitian ini mengambil 117 sampel perusahaan yang menjadi emiten di Bursa Efek Indonesia sepanjang periode 2015 – 2018. Hasil penelitian ini menjelaskan bahwasanya partisipasi dewan direksi dalam rapat direksi dan rapat gabungan tidak terbukti memberikan pengaruh yang signifikan terhadap profitabilitas, namun dengan mengunakan variable control DAR dan LnTA menunjukan bahwa hanya partisipasi dewan direksi pada rapat gabungan dengan komisaris terbukti memberikan pengaruh terhadap profitabitas perusahaan. Ini menunjukkan bahwa rapat strategis antar direksi dan komisaris memberikan pengaruh pada perusahaan dengan nilai asset yang relative besar. Dan frekuensi rapat direksi dan rapat gabungan direksi dan komisaris tidak terbukti memberikan dampak pada profitabitas perusahaan. Sementara dengan nilai perusahaan, frekeuensi rapat gabungan antara direksi dan komisaris memberikan pengaruh yang signifikan terhadap nilai perusahaan. Sedangkan partisipasi direksi pada rapat baik rapat direksi maupun rapat gabungan tidak memberikan pengaruh terhadap nilai perusahaan
Reaksi Pasar Modal di Asia Tenggara Terhadap Pandemi Covid-19
No full textCovid 19 is global case in almost around the world. Early April 2020, Covid 19 cases reached 1 million in a number of countries and increased significantly. This pandemic caused a major impact on economic activity, and more than 100 countries carried out a full or partial lockdown which resulted in economic disruption in many sectors including the stock market. This study investigation impact that occurs on the stock market, especially in Southeast Asia (Malaysia, Indonesia, Thailand and Singapore). Change in the composite index from the capital market are used as a proxy to measure market reactions using the OLS panel data regression model. The natural log of GDP is used as a control variabel for differences between the four capital markets. In addition, to control for the effect of different transaction days, a dummy variable is included in the regression model. The result show that changes in the number of covid 19 infections have been shown to significantly affect index changes. The market response in this regard has moved in a negative direction. Meanwhile, the measurement of the effect to the death to covid 19 is not proven to significantly affect change in the composite stock market index.

Covid 19 menjadi kasus global dengan penyebaran yang sangat cepat hampir diseluruh belahan dunia. Awal April 2020 kasus Covid 19 menyentuh angka 1 juta penderita yang tersebar di sejumlah negara dan terus meningkat secara signifikan. Pandemi ini berpengaruh besar terhadap aktifitas perekonomian hampir di seluruh dunia. Puncaknya, akhir Maret 2020 lebih dari 100 negara melakukan Lockdown baik secara penuh maupun sebagian yang memberikan dampak terbatasnya aktifitas ekonomi di berbagai sektor seperti transportasi, pariwisata, perbankan, asuransi termasuk pasar modal. Penelitian ini berupaya melihat dampak yang terjadi di pasar modal khususnya di empat negara di Asia Tenggara (Malaysia, Indonesia, Thailand dan Singapura). Perubahan Indeks gabungan dari pasar modal dipergunakan sebagai proksi untuk mengukur reaksi pasar dengan menggunakan pendekatan model regresi data panel Ordinary Least Square (OLS). Untuk mengendalikan dampak yang mungkin muncul dari perbedaan yang mendasar dari keempat pasar modal tersebut, dipergunakan log natural PDB sebagai variabel kontrol. Selain itu, untuk mengontrol efek perbedaaan hari transaksi dimasukkan pula variabel dummy didalam model regresi. Hasil menunjukkan perubahan angka terinfeksi COVID-19 terbukti secara signifikan mempengaruhi perubahan indeks. Respon pasar terkait hal tersebut bergerak kearah negatif. Sementara pengukuran terhadap pengaruh angka maninggal dunia akibat COVID-19 tidak terbukti secara signifikan mempengaruhi perubahan indeks pasar saham gabunga
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
