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

Istraživanje je obuhvatilo 87 ispitanika u mRNA skupini (prosječne dobi 35 god, udio žena 59% ) i 84 u vektorskoj skupini (prosječne dobi 44 godine, udio muškaraca 52%) kojima su određivani laboratorijski pokazatelji (TAT, F1+2, d-dimeri, IL-6, veliki ET-1, fibrinogen, VWF:Ac, CRP, KKS) prije, 7 i 14 dana nakon cijepljenja vektorskim, odnosno prije, 7 i 14 dana nakon 1. i 2. doze mRNA cjepiva.
Nakon cijepljenja zabilježen je porast vrijednosti d-dimera (P=0,004) i pad aktivnosti VWF-a u obje skupine (P<0,001 u) te porast CRP-a (P=0,006) u vektorskoj i velikog ET-1 (P<0,001) u mRNA grupi. Veći CRP (P=0,014) zabilježen je 7 dana nakon cijepljenja vektorskim cjepivom u odnosu na mRNA cjepivo. Kod svih ispitanika isključena je prisutnost protutijela na trombociti faktor 4.
Zaključno, statistički značajne razlike pokazatelja zgrušavanja i upale u našem istraživanju mogu se pripisati opće poznatoj i očekivanoj blagoj reakciji na cijepljenje SARS-CoV-2 cjepivima. Niti jedan ispitanik nije imao tromboembolijski incident u 6-mjesečnom periodu praćenja nakon cijepljenja.The main aim of our study was to investigate the effect of mRNA BNT162b2 and vector Ad26.CoV2.S vaccine against SARS-CoV-2 on the markers of hemostasis and inflammation.
The study included 87 subjects in the mRNA group (median age 35 years, 59% of women) and 84 (median age 44 years, 52% of men) in the vector group. All the laboratory parameters (TAT, F1+2, d-dimers, VWF:Ac, fibrinogen, big ET-1, CRP, CBC) were investigated before, 7 and 14 days after the vaccination in the vector group and before, 7 and 14 day after the 1st and 2nd dose in the mRNA group.
After vaccination with both vaccines higher levels of d-dimers (P=0.004) and lower levels of VWF:Ac (P<0,001) were noted. CRP levels were eleveted (P=0.006) in the vector group while in the mRNA group, higer levels of big ET-1 (P<0,001) were noted. Higher CRP levels (P=0.014) were present 7 days after the vector vaccine immunisation in comparisson with the mRNA vaccine. All the study participants tested negative for platelet factor 4 antibodies.
In conclusion, although statistically significant changes in the parameters of hemostatasis and inflammation have been obtained, they remained clinically irrelevant (no thromoembolic events have been noted in the 6-months surveillance period) and can be contributed to the wellknown reaction to the vaccination

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
