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
Sintesis dan karakterisasi karbon nanodot (C-Dots) berbahan dasar batang pisang menggunakan metode pemanasan microwave
Get PDFTelah berhasil disintesis material C-Dots dari batang pisang menggunakan teknik pemanasan microwave selama 7 menit pada suhu dan daya maksimum, pada variasi konsentrasi urea sebesar 0-175%. Hasil penelitian menunjukkan bahwa penambahan jumlah urea yang berbeda telah menghasilkan karakteristik C-Dots yang berbeda. Suspensi yang dihasilkan berwarna kuning pekat hingga bening. Berdasarkan hasil uji sinar UV-Vis di bawah eksitasi 365 nm dan 254 nm, sampel menghasilkan warna hijau dan biru, secara berurutan. Hasil karakterisasi PL menunjukkan bahwa penambahan urea dapat meningkatkan intensitas emisi PL, serta mengakibatkan blueshift pada rentang panjang gelombang, dan juga disebabkan karena adanya efek kuantum. C-Dots 25% memiliki sifat fluoresensi terbaik dengan intensitas tertinggi. Puncak spektrum emisi PL di bawah eksitasi 365 nm berada pada panjang gelombang 420-480 nm dengan emisi ungu hingga biru. Berdasarkan nilai absorbansi dari hasil karakterisasi UV-Vis spektra C-Dots batang pisang pada penelitian ini digolongkan material semikonduktor karena nilai energi band gap yang didapat sebesar 2,72-2,83 eV dengan ukuran partikel 7,03 hingga 7,18 nm.
C-Dots material has been obtained from banana pseudo-stems using microwave-assisted synthesis for 7 minutes at maximum temperature and power, at a variation in urea concentration of 0-175%. The results showed that the addition of different amounts of urea has resulted in different characteristics of C-Dots. The resulting suspension is solid yellow to clear. Based on uv-vis light test results below 365 nm and 254 nm excitation, the sample produces green and blue colors, respectively. Pl characterization results show that the addition of urea can increase the intensity of PL emissions, as well as result in blueshift at wavelength ranges, and is also due to the quantum size effect. C-Dots 25% has the best fluorescence properties with the highest intensity. The peak of the PL emission spectrum under 365 nm excitation is at wavelengths of 420-480 nm with purple to blue emissions. Based on the absorbance value of the characterization of UV-Vis spectra C-Dots banana stem in this study classified semiconductor material because the energy value of band gap obtained by 2.72-2.83 eV with particle size 7.03 to 7.18 nm
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
