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
Amartya Sen o prawach człowieka
No full textThe article discusses the idea of ‘human rights’ and the Amartya Sen’s reflections on that topic. By assumption, Sen does not present a catalogue of human rights, yet he claims that the language of human rights can be used to talk about the so-called human capabilities (the main concept of Sen’s theory). The aporia that exists in the current paradigm of human rights consists in the fact that it has been based on a few (liberal) foundations, while, on the other hand, it has been extended into a broad system of individual rights/entitlements conflicting with their foundation. Each of
those systems of rights entails a specific vision of social life. The liberal tradition postulates the existence of a minimal state, which guards freedom, life and property. In the leftist tradition, in contrast, there is postulated the existence of a welfare state, which satisfies people’s ever growing needs, based on an extensive bureaucracy and high taxes – under the patronage of the idea of social justice. Those social visions cannot be reconciled – they lead to conflicts. In this text, I present the problem of inconsistency and tension within the ‘human rights’, contrasting Amartya Sen’s theory with classical liberalism of John Locke. I claim that assessment of the contemporary ‘human rights’ theory should depend on whether a given theory is capable of proper
determination and – at least to some extent – solving the problem of incoherence and tensions present in the Western ‘human rights’ paradigm. It seems that Sen’s conception cannot meet that challenge
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
A portable VNA-based system for grid impedance measurements
No full textConducted emissions are strongly dependent on the grid and EUT impedance, to measure in live conditions. A portable system based on a low-cost VNA and two internal or external current probes is presented. It was verified in the lab against various calibration standards (50 Ω, mismatched termination, 150 Ω coupling-decoupling network and 100 pF capacitor) using a Agilent E5061B as reference. Results of calibration and the effects of probes non-linearity are provided, having considered both saturation (with an external bias circuit) and signal-to-noise ratio (by injecting external noise). The maximum observed spread of impedance magnitude is 1% for matched condition (50 Ω) and 10% in mismatched conditions. Performance can always be improved by using a more expensive and bulkier VNA
