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
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
The application of modern statistical approaches to identify consistent individual differences in the behaviour of wild postpartum female grey seals (Halichoerus grypus)
Get PDFConsistent individual differences (CIDs) in behaviour have been shown to occur in a large number of species. However, few studies have attempted to quantify CIDs in the behaviour of wild animals in their natural environment. Yet, in order to understand the ecological and evolutionary relevance of CIDs in behaviour, it is fundamentally important that we attempt to quantify them in wild animals, in situ.
In order to address this question, a three-step analytical approach was applied to data that were collected on wild postpartum female grey seals, which were part of a ‘hands-off’ observational study. Aspects of behaviour were highly repeatable across breeding seasons. The ‘alert’ behaviour in particular, remained highly repeatable irrespective of which individuals were included in the analyses. Furthermore, these robust repeatability estimates for the ‘alert’ behaviour persisted, despite controlling for social and environmental factors that are known to influence maternal behaviour.
Subsequently, the three-step analytical approach was applied to an independent dataset collected on postpartum female grey seals that are part of a long-term longitudinal study on reproductive variation. Similar patterns were observed in the results across the three steps, and once again, the ‘alert’ behaviour was one of the more repeatable behaviours. However, these highly repeatable behaviours did not explain any of the variation in commonly used proxies for short-term fitness. As a result, these preliminary findings add to the debate on whether or not CIDs in behaviour are adaptive or are a product of phenotypic and/or genotypic constraints. Consequently, the potential influence of CIDs in behaviour on fitness trade-offs, population dynamics and conservation and management practices shall be discussed.
The application of the three-step analytical approach to the independent dataset did raise some important methodological considerations, which shall be discussed in relation to developing guidelines for applying this approach to other datasets
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
RiCORE: risk-based consenting of offshore renewable energy projects.
