Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe 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
STK31 contains a putative D-box motif.
No full text<p>(<b>A</b>) A putative D-box motif is located within the amino acids 643–651 of STK31. The conserved position, Arg643 (R643), within the D-box was shown. (<b>B</b>) Asynchronized (Asy), M phase, and G2 stage AZ521 cells with STK31-GFP or STK31-GFP/D-box mutant expression were collected to perform the IB analysis using anti-GFP antibody. Expression levels of STK31-GFP are displayed as ratios. Phospho-histone H3 serine 10 (P-H3/S10) is a marker for mitotic cells. GAPDH is a loading control.</p
Variations on the Author
Full text link“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
Full text linkWe 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
General ethical and legal aspects of the use of genetically modified organisms (GMOs) for the biosensing of explosives
No full textThe EU project D-BOX tackles the burning issue of anti-personnel landmines and cluster munitions remaining from armed conflicts. This will be achieved through the development of innovative solutions that will be interfaced and integrated in a comprehensive toolbox concept that is going to provide demining stakeholders the advice for and the access to the most appropriate tools, methods and procedures. Among other things D-BOX includes the development of highly-sensitive biosensors for the detection of explosives. The consortium pursues a new approach in which a common soil bacterium is genetically modified to produce red fluorescent proteins upon recognition of TNT-signatures. The aim of this report is first to analyse the public acceptance and possible ethical objections to the use of G MOs for the biosensing of explosives. We further recommend necessary technical and non-technical measurements to meet the security needs and ethical concerns of the public. To achieve this aim the following issues are covered in this report. A desktop research on the public acceptance as well as on ethical aspects of GMOs in general has been performed. A series of expert interviews have been performed to learn about the public acceptance of the D-BOX biosensor. The legal aspects (directives and regulations) of the use of genetically modified biosensors have been described. The approval procedure for the experimental release as well as for the placing on the market of the GM biosensor has been explained in detail
Dispelling the Myths Behind First-author Citation Counts
Full text linkWe 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
