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
Novel pH-responsive nanovectors for controlled release of ionisable drugs
No full textA family of novel ‘smart’ drug nanovectors based on 2-(methacryloyloxy)ethyl-3-chloro-4-hydroxybenzoate (MCH), a functional pH-responsive monomer, and poly(methoxy-ethylene glycol) methacrylate (PEGMA) block copolymers is presented. Modification of the monomers' relative ratios allowed facile switching from micellar (PEGMA11-b-MCH21) to polymersome-based (PEGMA11-b-MCH38) drug delivery nanocarriers. The ability of the latter to incorporate model anticancer drugs – tamoxifen, paclitaxel and doxorubicin hydrochloride – was investigated. High drug loading – up to 18 w/w% – was observed for tamoxifen, a hydrophobic drug which bears an amino group able to form ion pairs with MCH acidic functionalities. Non-loaded nanovectors were characterized (CAC, DLS and TEM), and were found to be very stable under physiological conditions (PBS pH 7.4, 37 °C), even in the presence of 10% plasma proteins for at least 48 h. Tamoxifen loaded nanocarriers showed slow drug release at pH 7.4 and faster release after exposure to weakly acidic environments, due to the loss of polymer/drug ionic interactions. Importantly, at pH 7.4 tamoxifen-loaded PEGMA11-b-MCH21 micelles were found to be less cytotoxic than free tamoxifen against MCF-7 cells, while under more acidic conditions, at pH 6.8, the opposite behaviour was observed, with a 10-fold increase in cytotoxicity for the micellar nanocarriers. The empty nanocarriers were found to be non-toxic in 48 h incubation time experiments. Pharmacokinetic studies proved the increased half-life and the slower clearance of tamoxifen after encapsulation in the micelles. These PEGMA-b-MCH based nanoassemblies could represent a novel promising delivery platform for low molecular weight ionisable drugs
A language-based approach to categorical analysis
Full text linkThesis (S.M.)--Massachusetts Institute of Technology, Program in Media Arts & Sciences, 2001.Includes bibliographical references (p. 79-81).With the digitization of media, computers can be employed to help us with the process of classification, both by learning from our behavior to perform the task for us and by exposing new ways for us to think about our information. Given that most of our media comes in the form of electronic text, research in this area focuses on building automatic text classification systems. The standard representation employed by these systems, known as the bag-of-words approach to information retrieval, represents documents as collections of words. As a byproduct of this model, automatic classifiers have difficulty distinguishing between different meanings of a single word. This research presents a new computational model of electronic text, called a synchronic imprint, which uses structural information to contextualize the meaning of words. Every concept in the body of a text is described by its relationships with other concepts in the same text, allowing classification systems to distinguish between alternative meanings of the same word. This representation is applied to both the standard problem of text classification and also to the task of enabling people to better identify large bodies of text. The latter is achieved through the development of a visualization tool named flux that models synchronic imprints as a spring network.by Cameron Alexander Marlow.S.M
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
