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
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
Persepsi Guru Matematika Terhadap Penggunaan Google Formulir Sebagai Alat Evaluasi Pembelajaran di Sekolah Dasar
Get PDFThe presence of advanced technology in the current era makes learning evaluation also comes with digital-based, for example, Google Forms. From previous research, Google Forms has many advantages and is effectively applied. However, behind these advantages, of course, there are shortcomings found in Google Forms as a learning evaluation tool. This study aims to determine the perceptions of mathematics teachers towards the use of Google Forms as a learning evaluation tool and to determine whether or not the use of evaluation through Google Forms in mathematics subjects is effective. The method in this research uses qualitative research. This research was conducted for one day, namely on 10 October 2023 and took place at SD IT Al-Furqan Palangka Raya. The research subject was 1 person, namely the fourth grade Maths Teacher. The instrument in this study was an interview guide. The results showed that the perception of mathematics teachers towards the use of Google Forms as a learning evaluation tool in elementary schools was not effective for their students. Because, when teachers give evaluations to students through Google Forms, they will be able to search first through Google
Pengaruh NIM, BOPO, dan CAR terhadap profitabilitas dengan NPF sebagai variabel moderasi: Studi pada bank umum syariah di Indonesia periode 2019-2023
Get PDFINDONESIA
Penelitian ini bertujuan untuk menganalisis dan mengetahui pengaruh Net Income Margin (NIM), Biaya Operasional terhadap Pendapatan Operasional (BOPO), dan Capital Adequacy Ratio (CAR) terhadap Return on Assets (ROA) pada bank umum syariah di Indonesia selama periode 2019-2023. Populasi penelitian ini terdiri dari 15 bank umum syariah yang terdaftar di Otoritas Jasa Keuangan (OJK). Pengambilan sampel dilakukan dengan menggunakan purposive sampling, sehingga diperoleh 10 bank syariah di Indonesia sebagai sampel. Data yang digunakan adalah data sekunder yang diperoleh dari laporan keuangan tahunan masing-masing bank syariah yang diakses melalui situs web resminya. Penelitian ini menggunakan analisis regresi data panel dan melakukan uji interaksi, yang dikenal dengan Moderated Regression Analysis (MRA). Hasil penelitian menunjukkan bahwa, secara parsial, NIM tidak berpengaruh signifikan terhadap ROA, BOPO berpengaruh negatif signifikan terhadap ROA, sedangkan CAR tidak berpengaruh signifikan terhadap ROA. Non-Performing Financing (NPF) terbukti memoderasi pengaruh NIM terhadap ROA, tetapi tidak memoderasi pengaruh BOPO dan CAR terhadap ROA. Penelitian ini terbatas pada sampel 10 bank dan periode 2019–2023, sehingga hasilnya belum sepenuhnya mencerminkan seluruh sektor perbankan syariah. Oleh karena itu, disarankan untuk melakukan penelitian lebih lanjut dengan menambahkan variabel lainnya, memperluas cakupan periode penelitian, serta meningkatkan jumlah sampel. Selain itu, penelitian dapat mempertimbangkan objek lain selain Bank Umum Syariah untuk mendapatkan perspektif yang lebih komprehensif.

This study aims to analyze and determine the effect of Net Income Margin (NIM), Operating Costs to Operating Income (BOPO), and Capital Adequacy Ratio (CAR) on Return on Assets (ROA) at Islamic commercial banks in Indonesia during the 2019-2023 period. The population of this study consisted of 15 Islamic commercial banks registered with the Financial Services Authority (OJK). Sampling was carried out using purposive sampling, so that 10 Islamic banks in Indonesia were obtained as samples. The data used is secondary data obtained from the annual financial statements of each Islamic bank accessed through its official website. This study uses panel data regression analysis and conducts interaction tests, known as Moderated Regression Analysis (MRA). The results showed that, partially, NIM has no significant effect on ROA, BOPO has a significant negative effect on ROA, while CAR has no significant effect on ROA. Non-Performing Financing (NPF) is proven to moderate the effect of NIM on ROA, but does not moderate the effect of BOPO and CAR on ROA. This research is limited to a sample of 10 banks and the period 2019-2023, so the results do not fully reflect the entire Islamic banking sector. Therefore, it is recommended to conduct further research by adding other variables, expanding the scope of the research period, and increasing the number of samples. In addition, research can consider other objects besides Islamic Commercial Banks to get a more comprehensive perspective.
