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
Comparative risk of serious infections and tuberculosis of vedolizumab and ustekinumab compared with anti-TNF-α agents: A nationwide population-based study of South Korean patients with inflammatory bowel disease
No full text연구배경: 베돌리주맙/우스테키누맙과 항TNF-α제제를 투여받은 염증성 장 질환(IBD) 환자에서 중증 감염과 활동성 결핵 발병 위험을 비교하고자 하였다.
연구방법: 국민 전체 인구의 97%를 차지하는 건강보험심사평가원 청구자료에서 2017년부터 2020년까지의 추적관찰 기간 동안 두 군 사이에 입원/응급실 방문을 요하는 중증 감염 또는 활동성 결핵 발생의 차이를 분석하였다.
연구결과: 각각 1.55 ± 1.05년과 0.84 ± 0.69년의 평균 추적기간동안, 항TNF-α제제 또는 베돌리주맙/우스테키누맙제제를 투여 받은 환자들의 중증 감염 발생률은 각각 100인년 당 9.43건과 6.87건이었다. 다변량분석결과, 베돌리주맙/우스테키누맙과 항TNF-α제제 사이의 중증 감염 발병에는 통계적으로 유의한 차이가 없었으며, 보정 후 상대위험도(RR)는 0.81(95% 신뢰구간 [CI], 0.46-1.44, P = 0.478)였다. 또한, 항TNF-α제제 또는 베돌리주맙/우스테키누맙을 투여 받은 환자들 중에서 활동성 결핵 발생률은 각각 100인년 당 0.87건과 0.37건이었으며, 베돌리주맙/우스테키누맙과 항-TNF-α제 사이의 RR은 0.31(95% CI, 0.07-1.26, P = 0.101)였다.
연구결론: 베돌리주맙/우스테키누맙 치료는 국내IBD 환자들에서 항TNF-α제제와 비교하여 중증 감염 또는 활동성 결핵 발생률이 유사하게 나타났다.Maste
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
