No full textThe Composition of Naïve Powers
No full textWhat this chapter labels "the naïve view of powers" roughly holds that there is a strict correspondence between powers, their bearers, manifestations and activations, on one hand, and causal processes and their causes and effects, on the other hand. The naïve view of powers seems to run afoul of the possibility that powers compose. Therefore, most power theorists are inclined to reject it. This chapter develops an account of the composition of powers that can actually preserve the naïve view of powers. First, the naïve view is introduced. Then five cases of composition are examined, and it is briefly shown how such cases have led many philosophers to reject the naïve view (or some relevant portion of it). This is followed by an account of the composition of powers. This account is grounded on a distinction between component and derivative powers and on certain dependence relations holding between the latter and the former. This account is able to deal with the cases of composition presented and preserve the naïve view of powers. Finally, some objections and replies are anticipated. This chapter deals with the threat of overdetermination and (briefly) with the distinction between component and resultant forces-which is orthogonal to that between component and derivative powers
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
How the Libet Tradition Can Contribute to Understanding Human Action Rather than Free Will
No full textExperimental findings on the neurobiological roots of free will, pioneered
by Benjamin Libet’s work in the 1980s, have been met with a mixture of acceptance
and controversy. Discussions in both philosophy and cognitive neuroscience have
indeed generated an active and at times polarized debate on whether such findings
successfully disprove free will, which is the issue that is customarily considered to be
at stake. In our view, this polarization often comes at the expense of genuine crossdisciplinary
fertilization, which may turn into a mere attempt at bringing others
round to one’s own positions. In this chapter, we argue for an alternative approach.
In the first place, we claim that, in themselves, these findings do not address the
problem of whether free will, as intended in the philosophical tradition, is illusory or
not. However, we also claim that they should be taken as a valuable asset within a
more comprehensive theory of human action, aiming to explain how individuals
navigate the environment by means of a wide repertoire of more or less complex,
flexible, and intelligent behaviors
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
