    Going Beyond Counting First Authors in Author Co-citation Analysis

    The 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

    “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

    We 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

    We 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

    Are visual skills unimportant to Chinese readers in primary-school level?

    PURPOSE: Despite the visual complexity of Chinese words increases across grades, it is surprising that visual skills accounted for significant variance in Chinese word reading for kindergarten readers (Ho & Byrant, 1999; Ho & Byrant, 1997, Mcbride-Chang and Ho, 2000) but not for primary school readers (Chen and Wong, 1991; Hu and Catts, 1998; Huang and Hanley, 1997). This study aimed at re-exploring visual word recognition of primary school readers by adding in an intermediate variable, the knowledge of radicals, which is the basic orthographic unit of Chinese language. METHODS AND RESULTS: Study 1 explored the relationships among visual skill, orthographic skill and word recognition for 384 readers from Primary One to Four. After partialling out the effects of age and IQ, orthographic skills accounted uniquely for 5% of the variance in word recognition. Visual skills did not predict word recognition, but accounted for 4% of the variance in orthographic skills. These findings showed that radical knowledge is important in word recognition. Visual skills are employed in decoding radicals, rather than decoding words as a whole. This difference further implies an implicit perceptual decomposition of words into radicals during visual processing. Study 2 compared 30 dyslexic, 30 chronological-age matched and 30 reading-level matched readers on a variety of visual and orthographic tasks. The dyslexic group performed significantly worse than the CA group on all the tasks. Combined with the results from Study 1, it is speculated that the word decoding difficulties of dyslexic readers might stem from poor understanding of radicals, which in turn is visually dependent. To further explore why the dyslexic group perform poorly on visual tasks, Study 3 employed the eye-tracking technique on a visual discrimination task for 10 dyslexic readers, 10 CA control and 5 RL control. Compared with the CA group, the dyslexic group had significantly more fixations and longer fixation duration on the target form, and exhibited more sequential comparisons between their chosen form and the distracters. It is speculated that the dyslexic readers need more cognitive resources on identifying features of a visual form, and are more prone to the interference of visually-similar distracters. CONCLUSION: Radicals play an important role in the visual recognition of Chinese words. Readers start with learning single characters made up of one or few radicals, and progress into compound characters of multiple radicals. This may account for the importance of visual skills in word reading for kindergarten readers, but not for primary school readers. Reading difficulties in Chinese readers may stem from inefficient visual processing of radicals and interference of visually-similar radicals. These further hinder the development of orthographic skills, such as recognizing the positional and functional regularity of radicals, and subsequently leads to poorer word decoding performance.The 16th Annual Meeting of the Society for the Scientific Studies of Reading (SSSR 2009), Boston, MA., 25-27 June 2009

    koamabayili/VECTRON-author-checklist: VECTRON author checklist

    No full text
    We 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
