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
Combining valuable inventions: exploring the impact of prior invention value on the performance of subsequent inventions
No full textInnovation research widely acknowledges that most inventions are recombinations of existing ideas and technologies. Following this stream of research, this study analyses how the values of prior inventions used to develop a subsequent invention influence the value of the new invention. Building on evolutionary theory and research on technological search and technological paradigms, this article proposes a positive relationship between prior inventions’ value and subsequent invention value. The analysis of a large-scale patent data set of pharmaceutical and semiconductor firms largely confirms this notion; however, it also shows that the effect weakens when prior inventions are of “higher” value. Valuable prior inventions are also positively related to the likelihood that subsequent inventions are “breakthroughs”; however, while this effect also decreases when prior inventions hold higher values, the decreasing effect occurs only at particularly high levels of prior invention value. In contrast, combining valuable inventions limits the likelihood of generating poor invention outcomes value. In summary, while the results lend support to theories of evolutionary and cumulative technological progress, they also show that despite the recombination potential of technical knowledge, there are practical limits to the benefits of valuable inputs
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
Does it pay to stand on the shoulders of giants? An analysis of the inventions of star inventors in the biotechnology sector
No full textPrevious research has highlighted the importance of star inventors for invention success and firm performance. However, we have limited knowledge regarding the indirect influence of star inventors on knowledge generation and how the ideas of star inventors influence subsequent invention performance.Therefore, this study uses biotechnology patents to investigate the extent to which star inventors influence the value of subsequent inventions. It explores whether non-star inventors can build, just as successfully, on the ideas of star inventors as star inventors. The results show that having a star directly involved in the generation of an invention, and building upon other star invention/s, is positively related to invention performance. However, stars are not better than non-stars at building upon earlier star inventions, and in fact, stars building upon their own, previous, inventions negatively affects the out-come/s of their future inventions. Furthermore, these results hold true for both general and high-value inventions. Overall, this study highlights the importance of stars in cumulative knowledge generation,but also shows the limits of self-referencing and individual path-dependency
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
