Heraclitus Fragment B123 DK
No full textThis essay takes a simply stated but difficult to parse sentence from Heraclitus and works at extracting its meanings. For the Greeks, nature (phusis) is not a nature that pre-exists humans, but instead a widespread character of things, as applicable to a city as to a mountain. And even if the world becomes ever more visible to us, the nature of things is not on the surface, as phusis hides
Going Beyond Counting First Authors in Author Co-citation Analysis
No full textThe 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
How to Discern a Physical Effect from Background Noise: The Discovery of Weak Neutral Currents
No full textIn this paper I try to shed some light on how one discerns a physical effect or phenomenon from experimental background ‘noise’. To this end I revisit the discovery of Weak Neutral Currents (WNC), which has been right at the centre of discussion of some of the most influential available literature on this issue. Bogen and Woodward (1988) have claimed that the phenomenon of WNC was inferred from the data without higher level physical theory explaining this phenomenon (here: the Weinberg-Salam model of electroweak interactions) being involved in this process. Mayo (1994, 1996), in a similar vein, holds that the discovery of WNC was made on the basis of some piecemeal statistical techniques—again without the Salam-Weinberg model (predicting and explaining WNC) being involved in the process. Both Bogen & Woodward and Mayo have tried to back up their claims by referring to the historical work about the discovery of WNC by Galison (1983, 1987). Galison’s presentation of the historical facts, which can be described as realist, has however been challenged by Pickering (1984, 1988, 1989), who has drawn sociological-relativist conclusions from this historical case. Pickering’s conclusions, in turn, have recently come under attack by Miller and Bullock (1994), who delivered a defence of Galison’s realist account. In this paper I consider all of these historical studies in order to evaluate the philosophical claims that have been made on the basis of them. I conclude that—contrary to Bogen & Woodward (1988) and Mayo (1994)—statistical methods and other experimental inference procedures from the “bottom-up” (i.e. from the data to the phenomena) were insufficient for discerning WNC from their background noise. I also challenge Galison’s notion of the “end of experiments” and shall take the wind out of the sail of Miller and Bullock’s attack on some of Pickering’s claims, whilst rejecting Pickering’s sociological-relativist conclusions. Instead, I claim that an epistemic warrant from the ‘top down’ in the form of a theoretical postulate of the Weinberg-Salam model was necessary for “ending the experiments”, i.e. for the acceptance of WNC as a genuine phenomenon in the scientific community
Appropriate Similarity Measures for Author Cocitation Analysis
No full textWe 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
No full textWe 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
