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
Analyzing Speaking Performance Based On Drama Video From Syarifah Irnina Youtube Channel
Get PDFThis research aims to analyze the speaking performance of university students in short drama videos uploaded on the Syarifah Irnina YouTube channel. The research is conducted to answer two research questions: (1) How is the students’ speaking performance in the short drama videos? and (2) What are the strengths and weaknesses of the students’ speaking performance based on fluency, accuracy, pronunciation, and intonation? This study uses a qualitative approach with content analysis as the research method. The data were collected through observation and transcription of students’ dialogues from two short drama videos entitled Supporting Each Other and Beware of Stranger, performed by university students. The findings show that students demonstrate different levels of speaking performance across the four aspects. Fluency appears as a strength for several students who are able to speak smoothly with minimal hesitation, while others show interruptions caused by pauses and fillers. Accuracy is identified as a common weakness, particularly in sentence structure and word choice. Pronunciation is generally understandable, although minor errors occur in fast or spontaneous speech. Intonation varies among students, with some showing appropriate pitch patterns while others display limited variation. In conclusion, the strengths and weaknesses of students’ speaking performance are clearly reflected in the four assessed aspects, indicating uneven development of fluency, accuracy, pronunciation, and intonation among university student
Studi Antibodi Poliklonal Sebagai Kandidat Kit Deteksi African Swine Fever Berbasis Protein Rekombinan p22-ASFV Pada Hewan Coba Kelinci (Oryctolagus cuniculus)
Get PDFAfrican swine fever merupakan penyakit yang disebabkan oleh African swine fever
virus (ASFV) yang memiliki tingkat kematian yang tinggi pada babi. ASF menjadi
ancaman global karena kurangnya vaksin saat ini dan tidak tersedianya pengobatan untuk
penyakit yang memiliki angka morbiditas dan fatalitas kasus hingga 100% ketika strain
patogenik ASFV terlibat. Tujuan dari penelitian ini adalah untuk mempelajari karakter
poliklonal antibody hasil induksi protein spesifik p22-ASFV fragmen yang dikloning dan
diekspresikan pada media kultur sel bakteri E.coli BL21 pada kelinci jantan New Zealand
White (Oryctolagus cuniculus). Sampel protein rekombinan p22-ASFV yang digunakan
berasal dari PUSVETMA Surabaya. Lalu dilakukan purifikasi protein rekombinan p22
dengan metode elektroforesis SDS-PAGE dan dilanjutykan metode elektroelusi terhadap
protein dengan berat molekul 22 kDa. Imunisasi pada kelinci jantan New Zealand White
(Oryctolagus cuniculus) diberikan secara subkutan 800µl yang ditambah adjuvant CFA
(Complete Freund’s Adjuvant) dan IFA (Incomplate Freund’s Adjuvant). Metode indirect
ELISA dilakukan untuk mengukur titer antibodi dan melihat karakteristik antibodi
dilakukan dengan metode Western Blot. Uji imunogenisitas protein p22 menggunakan
metode indirect ELISA memiliki nilai titer antibodi tertinggi pada bleeding minggu ke-7
dengan nilai . Pada uji Western Blot menunjukkan bahwa antibodi anti-p22 dapat
mengenali antigen p22 pada berat molekul 21,93 kDa

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
