    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

    This research analyzes the running of stocks in companies which have been doing Initial Public Offering (IPO) in Indonesia Bursary Effect during the period of 2010. Measuring the running of stocks is a way to relate the aim of the companies which is to get some fund used for expansion and the aim of the investors which is to get a high return value. This research aims to reveal how short term stocks (for 3 months) and long term stocks (for 24 months) are run in the companies which have been doing IPO during the period of 2010; and to analyze whether there is any difference between the running of short term stocks and the running of long term stocks. By employing descriptive method using historical data and comparative study, this research involves twenty three companies as the sample. The results of this research in which the data are examined by using one sample t-test show that the running of short term stocks is outperformed,proved by t-arithmetic (3,028)> t-table (2,074); and the running of long term stocks is underperformed, proved by t-arithmetic (2,818)> t-table (2,074). Meanwhile the data which are examined by F-test with sig (t) =0,000 <= 0,05 show significant differences between theshort term stocks running (for 3 months) and the long term stocks running (for 24 months) in the companies which have been doing IPO during the period of 2010

    Tujuan penelitian ini untuk mengetahui pengaruh faktor makro ekonomi yaitu Inflas, Kurs, SBI dan Jumlah Uang Beredar terhadap IHSG. Pada tahun 2017 tingkat inflasi meningkat seharusya IHSG cenderung turun pada kenyataannya IHSG meningkat. Jenis penelitian explanatory dengan pendekatan kuantitatif. Metode analisis data menggunakan analisis regresi linier berganda. Data yang digunakan dalam penelitian ini data time series periode 2016-2018. Hasil penelitian menunjukkan Variabel inflasi tidak berpengaruh signifikan terhadap IHSG. Variabel Jumlah Uang Beredar berpengaruh positif dan signifikan terhadap IHSG. Variabel kurs sebesar berpengaruh negatif dan signifikan terhadap IHSG. Variabel SBI berpengaruh negatif dan signifikan terhadap IHSG. Variabel Inflasi, Kurs, SBI dan Jumlah Uang Beredar berpengaruh secara Simultan terhadap IHSG. Variabel makro ekonomi yang digunakan di dalam penelitian ini dapat menjelaskan IHSG sebesar 91% sedangkan sisa nya dipengaruhi oleh variabel lainnya. Sebaiknya investor sebelum meutuskan untuk berinvestasi harus mempertimbangkan juga variabel makro ekonominya. Perbedaan penelitian ini dengan penelitian sebelumnya menambahkan variabel Jumlah Saham yang Beredar karena merupakan faktor makro ekonomi

    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

    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
