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
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
The effects of risk-taking tendency on risk choice and pre- and post-decisional information selection
No full textIdeally, people seek and select information about unfamiliar risks with which they are confronted, before they make a risk choice. This study investigated what happens when people do not have this opportunity. The main question was how risk-taking tendency influences intuitive risk decisions and how this impacts subsequent information search and subsequent choices. In the present study, participants had to make a choice about an unfamiliar risk, either before or after they had had the opportunity to search for (risk-promoting or risk-averse) information. In the condition where they could only seek for information after they had made a choice, they had to reconsider their first choice and make a second risk choice. We expected that (1) risk-taking tendency would impact people's risk choices, but only in the situation where they have little information. On the basis of cognitive dissonance theory, it was furthermore predicted that (2) risk-taking tendency and (3) initial risk choice would affect risk information selection. Furthermore, we predicted that (4) the first risk choice and (5) the risk information selected would influence the subsequent risk choice. The results suggest that if people make a first, intuitive decision about an unknown risk, risk-taking tendency has an effect on the choice, but that this does not happen when people can first select information. Risk-taking tendency did not influence information selection, but initial choice did (although in another way than we expected). Furthermore, both the first risk choice and the risk information selected affected subsequent risk choices. These findings suggest that people often make initial intuitive decisions that are influenced by personality characteristics, and that are subsequently difficult to change
Measuring an individual's tendency to take risks: the Risk Propensity Scale.
No full textA new, short, and easily administered Risk Propensity Scale (RPS) is introduced that measures general risk-taking tendencies. This paper investigates the reliability and discriminant validity of the RPS. The RPS provided scores that yielded a good internal reliability coefficient and adequate test-retest reliability, and the scores correlated moderately to well with those of the Everyday Risk Inventory and the short Sensation-Seeking Scale. The correlation with the scores from other scales (Need for Cognition scale, Need for Structure scale, and 2 self-esteem scales) was low to moderate, indicating good discriminant validity. The findings are discussed in relation to risk-perception research using gambling experiments and in relation to their usefulness for risky decision-making research
