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
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
Challenges in the design of clinically useful brain-targeted drug nanocarriers
No full textAbstract: Nowadays, the delivery of drugs by means of intravenously administered nanosized drug carriers - polymer-drug conjugates, liposomes and micelles, is technically possible. These delivery systems are mainly designed for tumour therapy, and accumulate passively into tumours by means of the well known EPR effect. Targeted nanocarriers, that additionally contain ligands for receptors expressed on cell surfaces, are also widely studied but products of this kind are not marketed, and only a few are in clinical trial. Polymeric nanoparticles (Np) able to deliver drugs to the CNS were pioneered in 1995; a number of papers have been published dealing with brain-targeted drug delivery using polymeric Np able to cross the BBB, mainly for the treatment of brain tumours. At present, however, the translation potential of these Np seems to have been exceeded by targeted liposomes, a platform based on a well-known technology. This drug delivery system entered clinical trials soon after its discovery, while the challenges in formulation, characterization and manufacturing of brain-targeted polymeric Np and the cost/benefit ratio could be the factors that have prevented their development. A key issue is that it is virtually impossible to define the in vivo fate of polymers and especially in the brain, which is a regulatory requirement, and perhaps this is why no progress has been made. The most advanced Np for brain tumours treatment will be compared here with the published data available for those in clinical trial for tumours outside the CNS, to highlight the knowledge gaps that still penalise these delivery systems. At present, new approaches for brain tumour treatment are emerging, such as lipid Np or the use of monoclonal antibody (mAb)-drug conjugates, which avoid polymers. The possibility of success or failure in the approval of the polymeric Np currently in clinical trial will certainly affect the fate of brain-targeted Np. At present, the chances of their approval appear to be very low
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
