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
PENGARUH SIKAP DISIPLIN TERHADAP HASIL BELAJAR KOGNITIF SISWA KELAS V SD ISLAM DARUL HUDA
Get PDFTujuan dari penelitian yaitu untuk mengetahui pengaruh sikap disiplin siswa terhadap hasil belajar pada kelas V Sekolah Dasar Islam Darul Huda Semarang. Penelitian ini menggunakan metode ex post facto dengan jenis penelitian kuantitatif. Populasi dalam penelitian adalah seluruh siswa kelas V V Sekolah Dasar Islam Darul Huda Semarang tahun pelajaran 2022/2023 yang berjumlah 40 siswa dan seluruh populasi menjadi sampel dalam penelitian. Pengumpulan data menggunakan angket dan dokumentasi. Variabel penelitian meliputi sikap disiplin sebagai variable independen dan hasil belajar sebagai variable dependen. Perhitungan pengujian hipotesis menggunakan bantuan program SPSS versi 25. Teknik pengujian hipotesis menggunakan analisis regresi, sebelum dilakukan uji analisis maka dilakukan uji prasyarat yaitu uji normalitas dengan cara uji Liliefors dan uji liniearitas. Pengujian hipotesis dengan taraf signifikansi 5% diperoleh hasil yang menunjukkan bahwa terdapat pengaruh sikap disiplin terhadap hasil belajar siswa. Ditunjukkan oleh hasil koefisien korelasi (R) sebesar 0,752 dan koefisien determinasi (R2) 56,5%. Nilai signifikansinya sebesar 0,000 lebih kecil dari 0,05 yaitu 0,000 < 0,05 maka dapat disimpulkan bahwa Ho ditolak dan Ha diterima. Hal ini menunjukkan bahwa 56,5% hasil belajar dipengaruhi oleh sikap disiplin siswa. Kesimpulan dari penelitian ada pengaruh yang signifikan sikap disiplin siswa terhadap hasil belajar siswa kelas V Sekolah Dasar Islam Darul Huda Semarang.

Studi Pengaruh Penambahan Mg pada Logam Al terhadap Kekuatan Tarik dan Tekan Paduan Al-Mg Menggunakan Simulasi Dinamika Molekuler
Get PDFAluminum (Al) is widely used in industry because it is lightweight and strong. Magnesium (Mg), which is also lightweight and strong, is often alloyed with Al to form AlMg alloys that have high mechanical strength for various engineering applications. Simulations were performed at room temperature (300 K) with varying Mg concentrations of 0%, 5%, 10%, 15%, and 20%. The simulations were performed using the LAMMPS software with the EAM (Embedded Atom Method) potential approach. The primary focus of this study was to investigate the alloy's response to tensile and compressive loads at the atomic level, as well as changes in its crystal structure. The tensile test simulation results showed the highest maximum stress value in pure Al at 8.02 GPa, elastic modulus of 50.62 GPa, and yield point of 1.29 GPa. In compression testing, the highest maximum stress value of 5.77 GPa was observed in pure Al, with a yield stress of 5.33 GPa and an elastic modulus of 77.02 GPa. From an atomic structure perspective, the addition of Mg causes changes in the crystal structure, particularly a decrease in the number of FCC (Face-Centered Cubic) structures and an increase in other structures such as HCP, BCC, and amorphous. This structural transformation affects the mechanical properties of the AlMg alloy
