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
Identify key virulence gene as a control target to mitigate Pierce’s disease of grape
No full textXylella fastidiosa (Xf) is an important phytopathogen that infects a number of economically important crops including citrus, almonds, coffee and olive. The Xf Temecula1 strain causes Pierce’s disease of grapevines, a devastating disease to the viticulture industry. We deleted the pilG in Xf (XfΔpliG) and found that the mutant strain was avirulent. Type IV pili of Xyella fastidiosa are regulated by pilG, a response regulator protein putatively involved in chemotaxis-like operon sensing stimuli through signal transduction pathways. Results demonstrated that XfΔpliG showed significant reduction in cell-matrix adherence and biofilm production compared with wild type X. fastidiosa. In planta experiments showed that no Pierce’s disease (PD) symptoms were observed in grapevines inoculated with XfΔpilG, whereas grapevines inoculated with the wild type X. fastidiosa and complemented strain XfΔpilG-C developed typical PD symptoms. These results suggest that pilG plays a key role in X. fastidiosa virulence. To develop a target-basis of therapeutic control of X. fastidiosa virulence, we evaluate the effect of putative anti-virulence molecules on the target gene. Our studies identified several small molecules that exhibit effective suppression on twitching motility and virulence traits under in vitro and in planta evaluation. This study facilitates the development of a novel target-basis strategy to mitigate the Pierce’s disease of grapevines
Principled and practical approaches to data flows in international commercial arbitration -case study of England and Singapore
No full textA web of data flows captured by the data protection legislation prompts the need to raise awareness for partakers of an international arbitration and their multiple roles and responsibilities attaching to them. This paper will explicate the data flow/roles among the stakeholders and across borders examining the legal implications of data flows in international commercial arbitration. Focusing on England and Singapore, an in-depth legal examination of the local regulatory duty and the scope of data protection exemptions will be carried out. It will address specifically the interaction of data protection law and arbitration administered by LCIA and the SIAC. To do so, firstly, the research starts with a general discussion on arbitrator’s liability. Secondly, it provides an analysis of the data flows and partakers’ role at the intersections between data protection and arbitration. Thirdly, the risks and requirements relating to data flows, the use of cloud service, and beyond are examined. Fourthly, the extra-territorial effects of data protection laws and their intersection with the limitation of exemptions is highlighted with a case study of the practice of LCIA and SIAC. Finally, the research concludes with the recommendations of data mapping, risk assessment and raising awareness of regulatory duties imposed by extra territorial reach of “local” data protection laws.
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
